3 Adjust the documentation of autotest WRT atlocal.
4 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
5 when using Automake, to write a rule to produce atlocal, since it's

32 "make check" to ensure that the latter passes.
34 Use just-built tools, when possible.
35 * GNUmakefile (PATH): Set and export here, ...

104 Suggestions from Ralf Wildenhues.
106 2007-10-28 Jim Meyering <meyering@redhat.com>
108 Make inter-release --version output more useful.
110 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
111 which indicates that it is built using the 19th change set
112 (in _some_ repository) following the "v2.61a" tag, and that 58dd
113 is a prefix of the commit SHA1.
114 * build-aux/git-version-gen: New file.

120 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
121 not configure.ac, now that the version number changes automatically.
123 Ensure that $(VERSION) is up to date for dist-related targets.
124 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
125 git-version-gen doesn't match $(VERSION), but only for dist targets.

170 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
171 Use -1ull rather than -1u, since that causes problems with gnulib; see

198 Fix config header generation with AIX awk.
199 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
200 script, use helper array D_is_set, as `" 0"' does not evaluate

1422 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
1423 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1424 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1425 works but the latter doesn't, then it's a valid type.
1426 This lets people use function types and so forth.
1427 For C++ there doesn't seem to be a simple solution, so leave it alone.
1428 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1429 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
1430 AC_CHECK_TYPE; that wasn't documented or necessary.

1489 HP-UX's grep, like the one from Solaris, does not support that syntax.
1491 2007-03-09 Stepan Kasal <kasal@ucw.cz>
1493 * doc/autoconf.texi (Specifying Names): `--host' does not
1494 change the build type.
1496 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
1498 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
1499 suggests AC_CONFIG_HEADERS.

1598 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1600 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1601 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1602 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1603 substitution will still be done by the special code.
1604 Report by Jim Meyering.

1621 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1623 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1625 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1627 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1628 early on the reader side, drop stderr of the input to avoid
1629 `broken pipe' error output; this may happen even with shell
1630 builtin `echo' of some bash versions. Reports by Ian Macdonald
1631 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1633 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1635 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

1643 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1645 Fix some wording problems noted by Paolo Bonzini in:
1646 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1647 * doc/autoconf.texi (Signed Overflow Examples): Give more
1648 discussion about the allow_superuser_privileges example,
1649 and change it a bit to make things clearer.
1650 (Optimization and Wraparound): Clarify whether the compiler
1651 will generate an infinite loop for the example derived from
1652 Autoconf's mktime test.
1653 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1654 Also, clarify unsigned multiplication overflow.
1656 2007-01-04 Eric Blake <ebb9@byu.net>
1658 * bin/Makefile.am (RELEASE_YEAR): New macro.
1659 (edit): Use it to supply correct copyright year to scripts.
1660 * bin/autoconf.as (version): Use it.
1661 * bin/autoheader.in ($version): Likewise.
1662 * bin/autom4te.in ($version): Likewise.
1663 * bin/autoreconf.in ($version): Likewise.
1664 * bin/autoscan.in ($version): Likewise.
1665 * bin/autoupdate.in ($version): Likewise.
1666 * bin/ifnames.in ($version): Likewise.
1668 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1670 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1671 feedback. The most important changes document what happens when
1672 you convert an out-of-range value to a signed integer type, and
1673 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1674 a + b.
1676 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1677 rewrite, taking notions from the recent discussion on the gcc and
1678 autoconf mailing lists; please see
1679 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1680 and follow the many links.
1681 (Integer Overflow Basics, Signed Overflow Examples):
1682 (Optimization and Wraparound, Signed Overflow Advice):
1683 (Signed Integer Division): New sections.
1685 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1687 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1688 preprocessor macro arguments in traced name.
1689 * doc/autoconf.texi (Defining symbols): Document longstanding
1690 support for AC_DEFINE-ing macros with arguments, and document
1691 behavior when the same variable has multiple AC_DEFINEs.
1692 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1693 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1694 macros directly, giving much shorter and simpler code.
1696 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1698 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1699 space before "$ac_configure_args" to prevent a 'config.status
1700 --recheck' failure if ac_configure_args doesn't contain a leading
1701 space. This works around a problem with the XEmacs configure.ac,
1702 which uses the (undocumented) ac_configure_args variable
1703 inconsistently with Autoconf.
1705 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1707 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1708 Include <limits.h>, and use its INT_MAX to rewrite the
1709 j loop so that it does not overflow 'int'. Problem reported by
1710 Ralf Wildenhues in
1711 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1712 Play it safe by shifting left by 1 rather than multiplying by 2,
1713 as GCC is less likely to optimize this away when the value
1714 is signed (when it assumes overflow leads to undefined behavior).
1715 Also, don't assume time_t uses two's complement.
1717 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1719 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1720 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1721 dumps core on it. Report by Tim Rice.
1723 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1725 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1726 --disable-option-checking to --help output even when
1727 AC_PRESERVE_HELP_ORDER is not used.
1728 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1729 --with argument, rather than argument with [-.] replaced by
1730 underscores.
1731 * NEWS: Fix typo in previous change; the news was in the
1732 wrong section.
1734 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1736 * NEWS: Warnings are now generated by default for unknown
1737 --enable-* and --with-* options.
1738 * doc/autoconf.texi (Option Checking): Renamed from
1739 (Configure Option Checking). Tighten up the wording a bit.
1740 (External Software, Package Options): Cross-reference to Option
1741 Checking, and use this to shorten our section.
1742 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1743 "$x" to test "x$foo" != x.
1744 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1745 Don't warn if $enable_option_checking is "no".
1746 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1747 ac_unrecognized_opts to the empty string.
1748 Don't echo the unrecognized opts, as this might mishandle
1749 backslashes or leading -.
1750 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1751 usage next to the other --disable-FEATURE options in the
1752 help string.
1754 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1756 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1757 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1758 Print warning for unrecognized --with and --enable options
1759 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1760 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1761 Disable option checking when subdirs are configured.
1762 (AC_OUTPUT): If warnings are enabled, print warning about
1763 unrecognized --with and --enable options at the end of
1764 the configure output (as well as at the beginning).
1765 * doc/autoconf.texi (Option Checking): New node.
1766 Document new option warning functionality.
1768 2006-12-16 Eric Blake <ebb9@byu.net>
1770 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1771 * NEWS: Start news for current version.
1773 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1775 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1776 Define HAVE_GETMNTENT to 1, not to the empty string.
1777 Problem originally reported by Jochen Friedrich in
1778 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1780 This change prompted by a problem report by Andrey Simonenko in
1781 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1782 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1783 object-like macros only, in the traditional portable character
1784 set.
1785 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1786 Warn about attempts to define things that are not identifiers.
1787 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1788 awful hack that AC_DEFINEd macro names containing parentheses.
1790 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1792 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1793 too drastic, even if Texinfo in theory requires it for info mode.
1795 (config.status Invocation): Renamed back from Recreating a
1796 Configuration).
1797 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1798 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1800 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1802 * NEWS: Version 2.61a.
1804 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1805 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1807 * NEWS: Document changes with echo and printf, and the lack
1808 of limits on the total size of multi-line values of substituted
1809 variables, and the AC_FUNC_FSEEKO fix.
1811 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1813 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1814 Writing configure.ac.
1815 (Autoconf Input Layout): Renamed from configure.ac Layout.
1816 (Recreating a Configuration): Renamed from config.status Invocation.
1817 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1818 (acconfig Header): Renamed from acconfig.h.
1819 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1820 (Writing Testsuites): Renamed from Writing testsuite.at.
1821 (Autom4te Cache): Renamed from autom4te.cache.
1823 * BUGS: Remove mention of VPATH problem, since it's now documented
1824 not to be a bug in the Autoconf build procedure itself, but rather
1825 a problem with the proprietary `make' programs.
1827 * doc/autoconf.texi (Build Directories): Add a cross reference
1828 to VPATH and Make.
1830 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1831 * doc/standards.texi: Sync from gnulib.
1833 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1834 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1835 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1836 generated automatically.
1838 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1840 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1841 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1842 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1844 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1846 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1847 `CEOF$ac_eof' special marker, the awk script cannot contain a
1848 line matching `^CEOF', so this is not needed any more.
1849 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1850 special marker in the test.
1852 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1854 * tests/tools.at (autom4te preselections): Use `find -newer';
1855 remove one of the sleeps.
1857 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1858 more readable, using ...
1859 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1861 * doc/autoconf.texi (autoheader Invocation): Do not double-
1862 quote the parameter of `AH_BOTTOM' in the example.
1864 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1866 * doc/autoconf.texi (Configuration Headers): Remove the
1867 example with multiple input files.
1868 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1869 multiple input files.
1871 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1873 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1874 creating the awk substitution script, handle one input line at a
1875 time, so that the maximum length of a substituted (multi-line)
1876 value is not limited by the size of the sed pattern space.
1877 The trade-off is a slightly repetitive sed script.
1878 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1879 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1880 * tests/torture.at (Substitute a 2000-byte string): Increase the
1881 test with several long lines, they should not be caught by sed
1882 limits any more.
1884 * tests/tools.at (autom4te preselections): New test, to flag
1885 entries missing from autom4te.cfg.
1886 Report by David Byron <dbyron@hheld.com>.
1888 * tests/torture.at (Substitute a 2000-byte string): Actually use
1889 AC_PROG_AWK, so the last change works as intended.
1890 (Substitute and define special characters): Likewise.
1891 (Substitute a newline): Likewise.
1893 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1894 instead of `awk' consistently.
1895 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1896 * tests/torture.at (Torturing config.status): Test both the
1897 result of AC_PROG_AWK and plain awk.
1898 (Substitute a 2000-byte string): Likewise.
1899 (Substitute and define special characters): Likewise.
1900 (Substitute a newline): Likewise.
1902 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1904 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1905 can be assigned to a function pointer. Problem reported by
1906 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1907 part of a patch by Ralf Wildenhues in that same bug report.
1909 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1911 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1912 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1914 2006-12-01 Eric Blake <ebb9@byu.net>
1916 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1917 cross-compiling from cygwin to mingw.
1918 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1919 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1920 to lib/autoconf/c.m4.
1922 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1924 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1925 string for more reliable failure. Wrap the entire test that
1926 causes the broken Solaris printf to dump core, in a subshell,
1927 so the segmentation fault message is reliably suppressed.
1928 Fix shell expansion errors by using /usr/ucb/echo always;
1929 avoid an error on systems without it by another subshell.
1930 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1931 subshell-$as_echo to `as_echo', for better error message.
1933 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1935 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1936 `BASH_SOURCE' contain a newline, set them to empty, as they may
1937 not be unset.
1939 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1941 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1942 years and is too hard to maintain now. The last straw was
1943 reported by Jerker Baeck in
1944 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1945 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1946 * doc/autoconf.texi (Particular Functions): Move
1947 AC_FUNC_SETVBUF_REVERSED from here...
1948 (Obsolete Macros): ... to here. Say that it does nothing now.
1949 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1950 Turn into (almost) a no-op.
1952 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1953 (AC_C_VOLATILE):
1954 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1955 These macros are obsolescent and new applications shouldn't need them.
1956 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1957 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1958 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1959 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1960 (AC_FUNC_VPRINTF): Likewise.
1961 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1962 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1963 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1965 * doc/autoconf.texi (Setting Output Variables): Mention that
1966 @VAR1@VAR2 has unspecified behavior. Problem reported by
1967 Ralf Wildenhues.
1968 * NEWS: Mention this.
1970 * Makefile.am: Put only a single '#' into the copyright notice,
1971 so that it's also present in the output file. Standardize wording
1972 in makefile copyright notices to match GNU coding standards.
1973 * bin/Makefile.am: Likewise.
1974 * doc/Makefile.am: Likewise.
1975 * lib/Makefile.am: Likewise.

1981 * man/Makefile.am: Likewise.
1982 * tests/Makefile.am: Likewise.
1983 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
1984 one-line file.
1986 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1988 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1989 in the sed script that mangles the awk script: delete up to the
1990 first exclamation mark only.
1991 * tests/torture.at (Substitute and define special characters):
1992 Test '!' too.
1994 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1996 Rewrite config files generation: avoid quadratic growth in
1997 the number of substituted variables by using awk instead of sed
1998 for the bulk of the substitutions.
1999 * NEWS: Mention this.
2000 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2001 forbidden in the output (and thus input) file.
2002 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2003 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2004 generate just one large awk script for substitutions,
2005 eliminating much of the earlier complexity, while adding some
2006 new complexity. Only expand the substitution templates at
2007 configure time, for smaller configure script size. If
2008 _AC_SUBST_FILES are used, test 'awk' for working getline support
2009 at config.status time. If absent, interpolate through the
2010 shell. The awk script was written with much help
2011 from Paolo Bonzini and Paul Eggert.
2012 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2013 (_AC_SED_FRAG_NUM): Likewise.
2014 (_AC_SUBST_CMDS): Renamed from...
2015 (_AC_SED_CMDS): ...this.
2016 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2017 * tests/torture.at (Substitute a 2000-byte string): Also
2018 substitute a line with 1000 words, and a variable with several
2019 long lines.
2020 (Substitute and define special characters): Test awk special
2021 characters, and put substitution input strings `@foo@' in the
2022 output, to test that no recursion happens; test several other
2023 combinations from Paolo Bonzini.
2025 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2027 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2028 that replaced echo with AS_ECHO where this wasn't necessary.
2029 Problem reportd by Ralf Wildenhues.
2030 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2031 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2032 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2034 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2036 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2038 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2040 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2041 that traditional Awk lacks 3-arg "split". It has it.
2042 Mention that FS must be a single character, and a few other
2043 99-byte limits of traditional Awk.
2044 Mention that if (i in a) doesn't work with traditional Awk.
2046 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2048 * tests/autotest.at (BSx641-newline in command):
2049 (BS-BS-newline in command, BSx640-newline in command):
2050 (Newline-CODE-BS-newline in command):
2051 (Single-quote-BS-newline in command):
2052 (Single-quote-newline-BS-newline in command):
2053 Use printf '%s\n' instead of echo, for portability to hosts
2054 where echo interprets backslashes. This will break on hosts
2055 that lack printf, but for now let's assume all such hosts
2056 are dead (if not, we should get reports of test failures).
2058 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2060 'echo' has some portability problems, when given a first argument
2061 with a leading '-', or when given any argument containing '\'.
2062 Avoid using 'echo' in these cases.
2063 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
2064 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.

2087 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
2088 * bin/autoconf.as: Redo verbose flag implementation, as the old
2089 scheme wouldn't work with AS_ECHO.
2090 * lib/autotest/general.m4 (AT_INIT): Likewise.
2091 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
2092 Don't use ECHO_T, since ECHO_N is now reliable.
2093 * lib/autotest/general.m4 (AT_INIT): Likewise.
2094 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
2095 rather than using a here-document to put the script into a file.
2096 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
2097 use AS_ECHO.
2098 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
2099 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
2100 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
2101 bug, but we might as well stop using ECHO_N and ECHO_C internally.
2102 * lib/autotest/general.m4 (AT_SETUP): Likewise.
2103 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
2104 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2105 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
2106 operand, as AS_ECHO requires. Avoid double file name expansion.
2107 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
2108 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
2109 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
2110 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
2111 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
2112 Double-quote strings that would otherwise contain M4 comments.
2113 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
2115 * configure.ac (AC_INIT): Bump to 2.61a.
2116 * NEWS: Likewise.
2118 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2120 Version 2.61.
2122 * configure.ac (AC_INIT): Bump to 2.61.
2123 * NEWS: Likewise.
2125 * tests/autotest.at (Macro with backslash in a test title):
2126 Comment out for now, as this tests neither fails nor passes
2127 reliably. Problem reported by Ralf Wildenhues.
2129 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2131 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
2132 in previous change, which caused test failures.

2140 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
2142 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
2144 Import these changes from config via gnulib:
2146 2006-11-15 Ben Elliston <bje@gnu.org>
2148 From Josselin Mouette <joss@debian.org>:

2203 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
2205 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
2206 benefit of platforms like Solaris+GCC where it is common to have a
2207 non-working g++ installation.
2209 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2210 and Joel E. Denny <jdenny@ces.clemson.edu>

2219 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2220 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2221 Imported from a similar patch to gnulib by Bruno Haible.
2223 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

2239 Automake 1.10 nor future Automake 11.1 (sic).
2241 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
2242 and Stepan Kasal <kasal@ucw.cz>
2244 Handle special characters in test case titles correctly.
2245 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all

2252 Single-quote in a test title,
2253 Double-quote in a test title): Don't expect failure anymore.
2254 (Backslash in a test title): Put a non-whitespace character after the
2255 backslash so that Bourne shells might actually see it as an escape
2256 sequence.
2257 (Brackets in a test title,
2258 Pound in a test title,
2259 Comma in a test title,
2260 Quoted Macro in a test title,

2275 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2277 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2278 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2279 5363) simply issues a warning when dividing by zero at compile
2280 time. Problem reported by Elias Pipping.
2282 2006-10-26 Eric Blake <ebb9@byu.net>
2284 * THANKS: Update.
2285 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2286 show effect on macros that expand with commas.

2316 reported by Nelson H. F. Beebe for Coreutils 6.4.
2318 * tests/tools.at (autoconf --trace: user macros): Remove test
2319 for tracing multiline macros, since m4 1.4.7a uses a different
2320 way to number lines. Problem reported by Ralf Wildenhues.
2322 2006-10-24 Stepan Kasal <kasal@ucw.cz>
2324 * bin/autom4te.in (handle_m4): Do not redirect stdin to
2325 /dev/null since the heuristics for interactive behaviour was
2326 fixed in CVS m4.
2328 * bin/autom4te.in: With --force, always refresh the output
2329 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

2379 2006-10-14 Stepan Kasal <kasal@ucw.cz>
2381 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
2382 looking for special shell characters.
2383 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
2384 macro defined by AS_VAR_PUSHDEF before passing it as a
2385 parameter.
2386 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
2387 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

2396 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2398 (Imported from Automake.)
2399 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2400 which incorrectly sets the mode of an existing destination
2401 directory. In some cases the unpatched install-sh could do the
2402 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2403 system. We hope this is rare in practice, but it's clearly worth
2404 fixing. Problem reported by Alex Unleashed in
2405 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2406 Also, don't bother to check for -m bugs unless we're using -m;
2407 suggested by Stepan Kasal.
2409 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2411 Import this change from Automake:
2413 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

2415 is enabled by default with gnu and gnits strictness.
2416 Report from Bruno Haible.
2418 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
2419 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
2420 gnu and gnits modes.
2422 Import this change from Config:
2424 2006-09-20 Ben Elliston <bje@gnu.org>

2427 Import this change from Gnulib:
2429 2006-09-16 Karl Berry <karl@gnu.org>
2430 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
2431 to avoid sectioning errors.

2436 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
2437 (\quoteexpand): rename to \rquoteexpand.
2438 (\codequoteleft): new def, to look for @set codequotebacktick.
2439 (\lquoteexpand, \quoteexpand): new defs.
2440 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
2441 (\code): must use new \...Char values, since now ` is active.
2443 2006-08-26 Karl Berry <karl@gnu.org>
2444 * build-aux/texinfo.tex (\textdegree): New command.
2446 2006-08-12 Karl Berry <karl@gnu.org>

2453 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2455 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2456 added to the template can get mangled.
2458 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2460 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2461 include the default headers, and redefine obstack_chunk_alloc
2462 and obstack_chunk_free. Fixes false failure with glibc.
2464 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
2466 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
2467 for backward compatibility with Libtool 1.5.22. Problem reported
2468 by Ralf Wildenhues.

2481 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
2483 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
2484 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
2485 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
2486 Use a better substitute, by inspecting the output of "ls"
2487 rather than just using ":".
2488 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2489 rather than AS_EXECUTABLE_P, since we needn't worry about
2490 non-regular files here.
2492 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2493 due to configuration hassles with this. See Tonya Underwood's report
2494 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

2501 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
2503 2006-10-11 Stepan Kasal <kasal@ucw.cz>
2505 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
2506 initialization which is not inherited through the environment
2507 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
2508 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
2510 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
2512 * doc/autoconf.texi (Limitations of Usual Tools): Describe
2513 problems with mkdir -p -m.
2515 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
2517 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
2518 comment about ac_cpp_err; it was incorrect, and anyway
2519 ac_cpp_err is being removed below.
2520 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2521 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2522 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2523 nobody uses it.
2524 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2525 with werror_flag and conftest.err and so forth. This is more
2526 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2527 and anyway the user shouldn't normally want to see this gorp logged.
2528 Problem reported by Ralf Wildenhues.
2529 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2530 empty, not 'no', since the rest of the code uses 'test -z'.
2532 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2534 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2535 Use a single call to AC_DO_TOKENS rather than multiple, for
2536 efficiency.
2537 (_AC_LINK_IFELSE): Test that resulting file is executable.
2538 Problem reported by mwoehlke in
2539 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2541 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2542 than creating a file to use with test -x; this is much faster.
2544 2006-10-02 Bruno Haible <bruno@clisp.org>
2546 * lib/autom4te.in (Automake-preselections): Add
2547 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2549 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2551 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2552 standard error, `experr' should be used, not `expout'.
2554 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2556 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2557 fseeko testing program twice; just use the earlier result.
2558 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2559 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2560 still doesn't let the program compile.
2561 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2562 failed.
2564 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2565 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2566 include it, without including anything else.
2567 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2568 expressions.
2569 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2571 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2573 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2574 `error.h', and include it, for a `error_at_line' prototype.
2575 Use a nonempty format string in the link test.
2576 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2577 for a declaration of wait3.
2579 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2581 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
2582 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2583 can apply to constants too, and that it checks for macro defns.
2584 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2585 and simply cast the identifier to void. This handles structure
2586 values. Problem reported by Ralf Wildenhues.
2587 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
2589 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2591 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,

2659 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2660 mistaken comment: the path has to be relative; do not use
2661 the path at runtime.
2663 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2665 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2675 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2676 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2677 for the existence of the directory at configure-time. That's
2678 too late, anyway. Problem reported by Stefan Seefeld.
2680 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2681 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2682 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2684 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2686 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2687 works with GNU M4 1.4.3 again; make the normalized form
2688 match the current m4 message; fix the description.
2689 * test/tools.at (autom4te cache): Adapt to the change.
2691 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2693 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2694 to catch glibc bug 2821
2695 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2697 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2698 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2699 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2700 assume C89.
2702 2006-09-08 Stepan Kasal <kasal@ucw.cz>
2704 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

2720 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2722 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2723 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2724 accept files with extension `.f'. For consistency, also prefer
2725 xlf over f77.
2726 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2727 from last patch.

2748 except the first two arguments are reversed.
2749 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2750 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
2751 caches nor outputs a diagnostic. Suggested by Bruno Haible.
2752 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
2753 equivalent to the old AC_COMPUTE_INT.
2754 (AC_COMPUTE_INT): No longer caches or reports. New signature.
2755 All uses changed to AC_CACHE_CHECK_INT.
2756 * tests/base.at (AC_CACHE_CHECK_INT): New test.
2757 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
2759 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
2761 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
2762 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
2763 programs should use their Gnulib counterparts.
2764 * doc/autoconf.texi (Particular Functions): Likewise.

2766 obsolete macros with uses of non-obsolete macros.

2794 Fix Lex library problem reported to us by Julio Garvia.
2795 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
2796 for the default, which the user can override.
2797 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2798 deal with LEXLIB.
2799 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2800 didn't work if some values were cached but not others. Test for
2801 broken lex libraries like native ia64-hp-hpux11.22; see
2802 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2803 work around the problem by preferring an empty LEXLIB to -lfl or
2804 -ll. Let the user set LEXLIB='' to indicate no library needed.
2806 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.

2917 Bill Northcott in
2918 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

2931 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
2932 -Wundef -Werror". Problem reported by David Fang in
2933 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

2949 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
2950 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
2951 this.

2955 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
2956 problems with arg script text that doesn't end in newline, and

2959 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
2961 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
2962 check for libXt by a check for libX11.
2964 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2971 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
2972 --help' should mention that `--version' outputs configuration
2973 settings. Report by Bruno Haible.
2975 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2977 Fix test suite failures reported by Pierre in
2978 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
2979 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
2980 the compiler created a file "b.out" when it didn't create anything
2981 at all.

2983 Discard stderr too, when invoking the test script.

2987 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
2988 in the restoring of the werror flag.
2990 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>

2993 less skeptical about "volatile", after discussion with
2994 Bruno Haible on bug-gnulib.
2995 (Limitations of Usual Tools): Warn about sed stripping
2996 leading white space from text. From Bruno Haible.
2998 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3000 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
3001 compiler complains about it, even if things works after the
3002 complaint. Problem reported by Peter O'Gorman.
3004 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
3005 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3006 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3008 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3010 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

3020 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3022 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3023 under AC_C_VOLATILE.
3024 (Volatile Objects): Be a little less skeptical about what
3025 "volatile" means. Derived from thoughts by Ben Pfaff in
3026 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3028 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3030 * doc/autoconf.texi: Fix some typos.
3032 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3034 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3035 more globally, since the 2006-06-30 patch didn't suffice. Problem
3036 reported by Keith Marshall. Also, don't bother with builddir2,
3037 since it shouldn't be needed any more.
3039 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3041 * doc/autoconf.texi (Generic compiler characteristics):
3042 Document AC_COMPUTE_INT. Fix wrong statements on Default

3056 * NEWS: Document previous change.
3058 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3060 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3061 Require that long long int be at least 64 bits wide. C99 requires
3062 this and enough programs depend on it so we should check for it.
3063 Bruno Haible reports in
3064 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3065 that long long int is 32 bits wide with some nonstandard compilers.
3066 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3068 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3070 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3071 to a nonexistent file, so that we don't have to worry about
3072 a local site configuration that doesn't use /usr/local.
3073 Problem reported by Keith Marshall in
3074 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3076 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3078 * doc/autoconf.texi: Be more consistent about using @acronym with
3079 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3080 quite right (it talked about "OSF/Tru64", even though the
3081 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3082 and it even mentioned "OSF 4"!) and at this point there's little
3083 reason to talk about OSF any more, since it died in 1994.
3084 (Specific Compiler Characteristics): Simplify example of
3085 negative-size array.
3086 (File Descriptors): Reorder to make the text flow better.
3087 Remove joke about "appreciate the various levels"; I didn't get it.
3088 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3089 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3090 (File Descriptors, Limitations of Usual Tools):
3091 Tone down the advice against renaming or removing open files.
3092 (Limitations of Usual Tools): Add a new section, on 'rm'.
3094 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3096 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3097 -lXt in LIBS, idea from Karsten Hopp; this was due since
3098 this change:
3100 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3101 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3102 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3103 (which belong to Xt, not X itself). See Debian bug 327655.
3105 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3107 * configure.ac (AC_INIT): Bump to 2.60a.

3118 * config/texinfo.tex: Sync from upstream.
3120 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3121 quadrigraph correctly in traces.
3123 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3124 Fix typos.
3126 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3127 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3128 not defined.
3129 * doc/autoconf.texi (Changed Directory Variables): New node,
3130 to document the whole `datarootdir' business a bit better.
3131 * NEWS: Update.
3132 * tests/torture.at (datarootdir workaround): Extend test.
3133 Prompted by report by Alexandre Julliard.
3135 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3137 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3138 when using default mode of IBM C 6 for AIX. Problem and two-line
3139 fix reported by Larry Jones.
3141 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3143 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3144 about literal '${datarootdir}' if a definition is found in the
3145 output file.
3147 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3149 * NEWS: Use "M4" rather than "m4" when appropriate.
3150 Problem reported by Eric Blake.
3151 * doc/autoconf.texi: Likewise.
3152 Use @acronym around BSD, GCC, and GNU when appropriate.
3153 (Why GNU M4): Renamed from "Why GNU m4".
3154 (Redefined M4 Macros): Mention that Posix
3155 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3156 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3157 to int.
3159 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3161 * bin/autom4te.in (handle_output): Do not forbid the empty
3162 pattern.
3163 * tests/tools.at (autoconf: the empty token): New test.
3165 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3167 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3168 calls, so that we do not care whether they are LIFO or FIFO;
3169 in the m4_wrap, do not check which diversion is the topmost
3170 one, just check that the stack is balanced at the end.
3171 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3172 base diversion forever--pop the previous diversion before
3173 opening the new one; consequently, remove the m4_wrap call.
3174 * lib/autotest/general.m4 (AT_INIT): Likewise.
3175 * tests/m4sugar.at: Do not use
3176 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3178 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3179 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3181 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3182 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3183 Rework example of m4wrap token-pasting trouble so that it doesn't
3184 care whether it's LIFO or FIFO.
3185 Fix some "contrary to"s that are awkward in English.
3187 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3189 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3190 to `yes' instead of `int$1_t' if the type is found, for more
3191 consistent configure output (where $1 is the number of bits).
3192 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3193 Suggested by Bruno Haible.
3195 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3196 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3197 with system headers. Report by Bruno Haible.
3199 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3201 * config/config.guess, config/config.sub: Sync from upstream.
3203 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3204 in order to avoid picking up an older installed frozen m4sh.m4f.
3205 Besides an outdated shell startup, this could have been created
3206 by an earlier M4 version with incompatible frozen file format.
3208 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3210 * README: Recommend m4 1.4.4 instead of 1.4.3..
3211 * doc/autoconf.texi: Likewise.
3212 (Special Chars in Names): Say that $(.FOO) is portable, as
3213 suggested by Stepan Kasal.
3214 (Installation Directory Variables, Build Directories):
3215 (Automatic Remaking, Subdirectories, Fortran Compiler):
3216 (Making testsuite Scripts, Defining Directories):
3217 Quote variable usages better.
3218 (Making testsuite Scripts): Add clean-local rule to makefile
3219 snippet, by Eric Blake.
3220 (Installation Directory Variables): Fix table item font.
3221 Reword slightly to clarify. Generalize advice about
3222 not using special characters to include all file-related
3223 vars, not just VPATH.
3224 (Special Chars in Variables): Warn about special characters in
3225 $(srcdir) too.
3226 (Assignments): Clarify default-value example as suggested by
3227 Ralf Wildenhues in
3228 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3229 (Special Shell Variables): Note leading ./ or ../, as suggested
3230 by Eric Blake.
3231 (Limitations of Builtins): Under cd, warn about CDPATH.
3232 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3233 Ralf Wildenhues.
3235 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3237 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3238 `@var', for texi2html.
3239 (Systemology): Some more word wrapping, for DVI output.
3240 (autom4te Invocation): The short option for `--melt' is `-M',
3241 not `-m'.
3243 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3245 * doc/autoconf.texi: More formatting and English tweaks,
3246 many suggested by Ralf Wildenhues.
3247 Reword to avoid "@code{...}'s" and the like, since it's ugly
3248 with Emacs info mode. discontents -> woes.
3249 Put a few "will"s back. time stamp -> timestamp.
3250 side-effect -> side effect.
3252 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3254 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3255 Warn about $@ not persisting. Problem reported by Julien Danjou in
3256 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3257 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3258 Mention other special chars, too.
3260 2006-06-14 Eric Blake <ebb9@byu.net>
3262 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3264 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3266 * doc/autoconf.texi: Some systematic minor improvements, as
3267 follows. Use "makefile" when talking about makefiles
3268 generally (which might be named "makefile" or "Makefile" or even
3269 "foo.mk"), "Makefile" when talking about a specific makefile
3270 called "Makefile". This unclutters the text from weird quotes
3271 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3272 values" rather than "@var{foo}s" and similar constructs containing
3273 "}s". Use "Make rules" rather than "Makefile rules". Minor
3274 English-language improvements. Change the prefix "sub-" to "sub"
3275 and "re-" to "re".
3276 Put blank lines around examples more consistently.
3277 Avoid "rather" and "very" as intensifiers.
3278 Avoid "will" as an auxiliary.
3279 (Limitations of Make): Split this node into....
3280 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3281 (Leading _ in Macro Names, Backslash-Newline-Newline):
3282 (Backslash-Newline Comments, Long Lines in Makefiles):
3283 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3284 (obj/ and Make, make -k Status, VPATH and Make):
3285 (VPATH and Double-colon, $< in Explicit Rules):
3286 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3287 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3288 New nodes, resulting from splitup of Limitations of Make.
3289 All cross-references changed. Raise the top node from
3290 a section to a chapter, and all subnodes accordingly.
3291 Redo the introductory wording to match the new organization.
3292 (Installation Directory Variables): Use an example that is
3293 closer to what Autoconf actually does. Mention that VPATH's
3294 value should not contain metacharacters or white space.
3295 (Fortran Compiler): Fix a VPATH bug in an example.
3296 (Leading _ in Macro Names): Mention that this problem is no longer
3297 of practical concern.
3298 (VPATH and Make): Reword the advice to make it clearer
3299 that Autoconf and Automake support VPATH in non-GNU make, but
3300 many packages have bugs in this area.
3301 ($< in Explicit Rules): Refer to Build Directories rather
3302 than using a (non-VPATH-safe) example.
3303 (Automatic Rule Rewriting): Mention the sort of disaster that
3304 can ensue with Solaris-style rule rewriting with VPATH.
3306 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3308 * doc/install.texi (Compilers and Options): Weaken the
3309 suggestion to use GNU make for VPATH builds.
3311 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3312 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3314 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3315 in regular expression.
3317 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3319 * doc/autoconf.texi (Installation Directory Variables):
3320 Drop extra @samp from `@table @samp' item.
3321 (Limitations of Usual Tools): Comment fix.
3322 Do not nest @samp just to point to other table items.
3323 (Writing testsuite.at) <AT_CHECK>: The second argument to
3324 `@dvar' is already @samp'ed.
3325 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3326 do not use @var in the second argument.
3328 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3330 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3331 $as_shell.exe too. Problem reported by Andreas Buening in
3332 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3334 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3336 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3337 `unused variable' compiler warning, for `-Wall -Werror'.
3338 Reported by Jaap Haitsma in
3339 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3341 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3343 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3344 case the compiler dumps core. Problem reported for
3345 OpenServer 5.0.7 by Tim Rice in
3346 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3347 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3348 Likewise.
3350 2006-06-06 Tim Rice <tim@multitalents.net>.
3352 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3353 "ERROR" only shows up in "make check" output if there is an
3354 error.
3356 2006-06-06 Eric Blake <ebb9@byu.net>
3358 * tests/tools.at (automatically allowed tokens): Fix typo.
3360 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3362 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3364 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
3365 typically overflows on x86 CPUs, even though the C standard
3366 requires otherwise.
3368 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3370 * configure.ac (AC_INIT): Bump to 2.59e.
3371 * NEWS: Update.
3373 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3375 Version 2.59d.
3377 * config/texinfo.tex: Sync from upstream.
3379 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3380 seen, invoke libtoolize with `--ltdl' argument.
3381 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3382 * NEWS: Update.
3383 Suggested by Eric Blake.
3385 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3387 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3388 reported by Ralf Wildenhues.
3389 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
3391 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3393 * THANKS: Update.
3395 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3397 * doc/autoconf.texi: Modernize some of the references to Solaris.
3399 2006-06-05 Stepan Kasal <kasal@ucw.cz>
3401 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
3402 message issued by AC_REQUIRE.
3403 * tests/m4sugar.at: Check m4_require's error message.
3404 * tests/base.at: Check AC_REQUIRE's error message.
3405 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3406 to...
3407 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3408 AT_CHECK_M4.
3409 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3410 `expout' as the last parameter.
3411 * tests/tools.at: Adapt to the above change.
3413 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3415 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3416 information about race-free implementations of mkdir.

3421 * bin/autoconf.as (Usage): Likewise.
3422 * bin/autom4te.in (help): Likewise.
3423 * doc/autoconf.texi (autom4te Invocation): Likewise.
3425 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
3427 * NEWS: GNU make now recommended for VPATH builds.
3428 Mention that some macros are now documented to be obsolescent.
3429 * doc/autoconf.texi:
3430 Prefer "current" to "modern" to describe
3431 currently-used (albeit perhaps old-fashioned) hosts.
3432 Mention which ancient features no longer need to be worried about.
3433 setgid -> set-group-ID
3434 setuid -> set-user-ID (these are the Posix terms)
3435 Fix some misuses of "only".
3436 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3437 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3438 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
3439 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
3440 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
3441 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
3442 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
3443 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
3444 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
3445 Mention that these macros are obsolescent.
3446 (Installation Directory Variables): shall -> should
3447 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3448 Mention that it's now safe to use 3 and 4.
3449 (Limitations of Usual Tools): cp -r is now specified by Posix.
3450 Omit longwinded and obsolescent discussion of cp -f.
3451 Modernize discussion of expr, ls.
3452 (Limitations of Make): Modernize discussion of VPATH builds.
3453 Mention $? as a workaround in some cases.
3454 * doc/install.texi (Basic Installation):
3455 Mention "./configure; make; make install" first. Be more
3456 specific about why this file is generic. Remove unnecessary
3457 parens. Remove misleading "only". Remove obsolete advice
3458 about csh. Don't say "configure" takes awhile; say it
3459 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3460 and CC=c99 rather than CC=c89, as these are blessed by current
3461 Posix. Recommend GNU make if doing a VPATH build.
3463 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3465 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3466 examples involving shell prompts.
3468 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3469 and Paul Eggert <eggert@cs.ucla.edu>
3471 * doc/autoconf.texi (Here-Documents): Add details about the
3472 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3473 use "here-documents" instead of "here documents".
3475 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3477 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3479 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3481 * doc/autoconf.texi (File System Conventions): Warn about ":"
3482 anywhere in directory names.
3484 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3486 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3487 about quoting the case statement, just in case.
3488 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3489 was fixed in ksh93g; reported by Ralf Wildenhues.
3491 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3493 * doc/autoconf.texi (System Services): Do not document
3494 overriding EXEEXT via ac_cv_exeext=ext.
3495 (Particular Programs) <AC_PROG_MKDIR_P>:
3496 Document that ${MKDIR_P} understands --.
3497 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3498 comment.
3500 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3502 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3503 argument with leading hyphen. Problem reported by Paul Eggert.
3505 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3507 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3508 about quoting ac_try: quote all of it, if any of it seems suspicious.
3509 This means we don't have to worry about ${ or sed any more.
3510 Also, double-quote the case statement, to work around misuses via
3511 underquoting as reported by Ralf Wildenhues in
3512 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3513 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3514 undocumented and dangerous macro.
3515 Problem reported by Ralf Wildenhues in
3516 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3518 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3520 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3521 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3522 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3524 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3526 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3527 since evidently some packages rely on the old, broken behavior.
3528 Problem reported by Ralf Wildenhues in
3529 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3530 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3531 pre-2006-05-26 definitions, but leave in the comments that
3532 these macros are dangerous and should not be used.
3533 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3534 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3535 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3536 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3537 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3539 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3541 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3542 the use of 'tr', since this is our only use of 'tr'.
3544 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3545 and Paul Eggert <eggert@cs.ucla.edu>
3547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3548 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3550 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3552 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3553 the output file in the `${datarootdir}' test.
3555 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3556 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3558 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3559 mention of `datarootdir' in the input file(s), but literal
3560 `${datarootdir}' in the output file, and we haven't warned yet,
3561 then warn as well: the user may have (erroneously) used
3562 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3563 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3564 * tests/torture.at (datarootdir workaround): Extend this test.
3565 * NEWS: Update.
3567 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3568 and Paul Eggert <eggert@cs.ucla.edu>
3570 * doc/autoconf.texi (autoheader Invocation): The first argument to
3571 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3572 alternatives and clear up the language a bit.
3574 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3576 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3577 ac_config_guess, ac_config_sub, ac_configure.
3578 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3579 Fix typo that prevented an unnecessary space from being removed.
3580 Problems reported by Ralf Wildenhues in:
3581 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3583 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3585 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3586 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3587 Don't use the term "thread-safe" to talk about mkdir race
3588 conditions, since the problem is more a process than a thread
3589 issue. Problem reported by Stepan Kasal in:
3590 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3591 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3592 the test for 'install' more closely. Look at MKDIR_P first.
3593 Look in the PATH, and at /opt/sfw/bin.
3594 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3595 Don't bother to try mkdir -p, since we already check mkdir --version;
3596 just look at the version number. (There's no easy way to check
3597 for race-free implementations.)
3598 * tests/tools.at (autoconf: subdirectories): Adjust to above
3599 changes, since MKDIR_P now might end in "/mkdir -p".
3601 * doc/autoconf.texi (autoheader Invocation): Mention that the
3602 first arg of AC_DEFINE_UNQUOTED must be a literal.
3603 Problem reported by Ben Pfaff in
3604 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3606 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3607 * doc/autoconf.texi (Special Chars in Variables): New section.
3608 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3609 (Installation Directory Variables): Quote $(datadir) better.
3610 (Limitations of Builtins): Describe some of eval's trickiness.
3612 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3613 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3614 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3615 in front of every arg, not just trailing args. Quote apostrophes.
3616 (_AC_EVAL_ECHO): New macro.
3617 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3618 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3619 removed.
3620 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3621 exposed by quoting of eval argument. Put the command on line line
3622 so it logs better.
3623 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3624 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3625 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3626 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3627 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3628 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3629 Use eval more safely.
3630 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3631 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3632 to be replaced.
3633 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3634 lines, exposed by quoting of eval argument.
3636 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3637 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3639 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3640 initialization of `ac_cv_exeext', do not override it if it was
3641 already set, unless it was set to `no', for compatibility with
3642 Autoconf-2.13, and comment this.
3643 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3644 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3645 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3646 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3647 Document that this test may be overridden by setting
3648 `ac_cv_exeext'.
3650 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3652 Revert these two patches:
3654 2006-04-06 Eric Blake <ebb9@byu.net>
3655 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3656 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3657 2006-04-01.
3659 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3660 Clean up _AC_COMPILER_EXEEXT* macros.
3661 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3662 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3663 ac_file to the name of the default output file and call
3664 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3665 initial `rm' of the candidate files...
3666 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3667 the same list in subsequent `rm' calls, and for the temporary
3668 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3669 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3670 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3671 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3672 no longer needed) by libtool. Make it a cache check.
3673 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3674 copied here by mistake.
3675 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3676 _AC_COMPILER_EXEEXT.
3677 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3678 _AC_COMPILER_OBJEXT directly.
3679 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3681 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3683 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3684 Fix description of how the buggy `sed' works.
3686 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3688 Sync from Automake:
3690 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3691 ENOLCK. Only mention `make -j' when applicable. Only raise
3692 fatal errors when `make -j' is involved. Improve error message.
3694 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3696 * doc/autoconf.texi (Here-Documents): We now know more about
3697 the variable expansion in here documents bug.
3698 Thanks to Tim Rice and Stepan Kasal.
3700 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3701 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3703 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3705 * tests/autotest.at (Multiline command from M4 expansion):
3706 No failure to be expected if the shell quotes newlines in
3707 commands in the `set -x' output. Report by Tim Rice.
3708 * THANKS: Update.
3710 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3712 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3713 expansion in the here-documents used by config.status, as that
3714 runs afoul of the Korn shell version M-12/28/93d bug described in
3715 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3716 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3717 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3719 2006-05-23 Jim Meyering <jim@meyering.net>
3721 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3722 Fix typo introduced with 2006-04-02 change. It reversed the sense
3723 of the test.
3725 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3727 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3728 ac_dB slightly, to save bytes in the script.
3729 Max out at 50 lines, rather than 96; this is more likely
3730 (though not guaranteed) to avoid obscure 'sed' failures.
3732 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3734 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3735 `tr -d -' as bad option argument. Work around this by deleting
3736 an unrelated character.
3737 Report by Tim Rice <tim@multitalents.net>.
3739 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3740 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3741 Stepan Kasal <kasal@ucw.cz>
3743 * doc/autoconf.texi (Particular Programs): Do not promise that
3744 we always prefer the GNU version of the program, and that we
3745 search according to PATH; both rules can have exceptions.
3746 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3747 AC_PROG_SED. Move descriptions of limitations
3748 to the Limitations of Usual Tools section.
3749 (Limitations of Usual Tools) <sed>: Mention script length
3750 limitations with Solaris /usr/ucb/sed.
3751 <grep>: Fix wording for empty alternative. Mention that -c and
3752 -l should not be combined, and that -E and -F should not be
3753 combined.
3755 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3756 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3758 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3759 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3761 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3763 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3764 AC_DEFINE is now passed to m4_pattern_allow.
3765 * NEWS: Mention that; likewise for AC_SUBST.
3766 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3767 the parameter to m4_pattern_allow.
3768 * tests/tools.at: Add a check for that.
3770 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3772 * lib/autoconf/status.m4: Fix typos.
3774 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3776 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3777 only the files that this macro generates.
3779 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3781 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3782 the HP-UX sed limitation of 99 commands, labels do not count.
3783 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3784 in the comment.
3785 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3787 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3789 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3790 Import the following fix from coreutils:
3792 2006-01-13 Jim Meyering <jim@meyering.net>
3794 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3795 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3796 not double-quote uses of that variable, to accommodate the rare
3797 case in which getmntent is available in none of the libraries
3798 checked. This happens at least on FreeBSD 5.0.
3800 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3802 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3803 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3804 some other programs unwisely rely on these undocumented vars.
3805 But put in warning comments about them.
3806 Problem reported by Ralf Wildenhues in
3807 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3808 * NEWS: Document that these variables are intended to go away.
3810 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3812 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3813 and set the language to C++ (analogous to the equivalent Fortran
3814 tests).
3816 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3817 * doc/autoconf.texi (C++ Compiler): Document it.
3818 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3819 * NEWS: Update.
3821 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3823 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3824 that caused config.status to generate 100-command sed scripts; the
3825 portable limit is 99.
3827 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3829 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3830 variable `ac_d' instead of `d' to avoid infringing namespace.
3831 Report by Ralf Menzel.
3833 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3835 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3836 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3837 * tests/tools.at (autoconf: subdirectories): New test, taken from
3838 the corresponding problem report by Ralf Wildenhues in:
3839 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3841 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3842 Quote some uses of shell variables if they might suffer unexpected
3843 globbing. This doesn't fix all instances of quoting problems that
3844 I found, just the easy ones that look safe.
3845 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3846 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3847 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3848 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3849 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3850 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3851 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3852 Likewise.
3853 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3854 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3856 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3858 * bin/autoreconf.in ($help): Reword according to the manual.
3859 Suggested by Olly Betts.
3861 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3862 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3864 * bin/autoreconf.in: Pass the directory argument to
3865 `require_configure_ac'. Fix comment.
3866 * tests/torture.at (Configuring subdirectories): Expose this.
3867 Reported by Olly Betts.
3869 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3871 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3872 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3873 Automake as follows:
3875 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3876 `$configure_in' instead of `configure.in', to preserve
3877 directory component.
3879 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3881 * config/config.guess, config/config.sub, config/texinfo.tex,
3882 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3884 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3886 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3887 test for C99 conformance; (bool) 0.5 is an integer constant
3888 expression, but (bool) -0.5 is not. Problem reported by Fedor
3889 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3891 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3893 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3894 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3895 Warn about obsolete install-sh files. Remove stray sentence
3896 fragment and fix cross reference.
3897 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3898 install -d; this undoes the 2006-05-10 change.
3899 (MKDIR_P): Mark with AN_MAKEVAR.
3900 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3901 that we don't require $INSTALL to be thread-safe. Move comments
3902 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3903 of AC_PROG_INSTALL. Output a message saying that we're checking
3904 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3905 MKDIR_P instead of AC_SUBST.
3906 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3907 Special magic for MKDIR_P, too.
3908 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3909 a dnl.
3910 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3912 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3914 Sync from Automake, as follows:
3916 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3917 * config/install-sh: Initialize IFS, so field splitting isn't
3918 turned off later.
3919 * config/mkinstalldirs: Likewise.
3920 * config/missing: Remove superfluous quotes. Replace all uses of
3921 `[' by `test', for consistency, and for..
3922 * config/missing (sed_minuso, sed_output): New variables.
3923 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3924 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3925 Fixes `missing' to detect `--output' for help2man. Fixes
3926 PR automake/483. Report by Dennis J. Linse.
3927 (autom4te): Document in `missing --help'.
3929 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3931 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3932 * config/install-sh: Don't use 'path' to talk about file names,
3933 as per GNU coding standards. Close a race condition reported by Ralf
3934 Wildenhues and Stepan Kasal. There is still a race condition
3935 on hosts that predate Posix 1003.1-1992, but we can't help this.
3936 Don't mishandle weird characters like space on pre-Posix hosts.
3937 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3938 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3939 AC_PROG_MKDIR_P from AS_MKDIR_P.
3940 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3941 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3942 earlier editions are not (including Automake 1.8.3).
3943 Do not suggest mkinstalldirs for thread-safety.
3944 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3945 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3946 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3947 presence of special characters and race conditions.
3948 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3949 in Autoconf's name space.
3951 2006-05-10 Bruno Haible <bruno@clisp.org>
3952 and Paul Eggert <eggert@cs.ucla.edu>
3954 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3955 from Automake with minor changes.
3956 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3958 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3960 * config/install-sh: Update to Automake CVS version, as follows:
3961 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3962 * lib/install-sh: Simplify the expr implementation of dirname.
3963 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3964 * lib/install-sh: Handle --, and diagnose unknown options.
3966 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3968 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3969 `./autom4te' to create `./testsuite', since the `all' target
3970 will ensure its presence, but `installcheck' should not create
3971 the uninstalled wrappers.
3973 * tests/torture.at (Unusual Automake input files): Skip if we
3974 detect automake < 1.8.
3976 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3978 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3979 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3980 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3981 * NEWS: Update.
3983 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3985 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3986 munge (multiple) white space and other oddities.
3987 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3988 single quotes in variable assignment.
3989 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3990 and similar failures by adding multiple spaces, tabs, and other
3991 special characters.
3992 Report and different test suggested by Francesco Romani
3993 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3995 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3996 single quotes, we only need to search for single quotes; this
3997 both simplifies the search pattern, and makes us less
3998 susceptible to `echo' variations for arguments not containing
3999 single quotes.
4000 (_AC_ARG_VAR_VALIDATE): Likewise.
4002 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4004 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4005 `$*' and IFS concatenation issue with traditional shells and
4006 bash-2.04. Report by Seanster@Seanster.com.
4008 2006-05-03 Bruno Haible <bruno@clisp.org>
4010 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4011 precisely which Mac OS X versions have the od problem.
4013 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4015 * doc/autoconf.texi: Use @option systematically.
4017 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4018 and Bruno Haible <bruno@clisp.org>
4020 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4021 about 'od'.
4022 (Integer Overflow): Mention the special case of integer division
4023 overflow.
4025 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4027 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4028 traditional shells like the Solaris one that do not use the
4029 first IFS character for assembling `$*'.
4030 Prompted by a related report from autoconf_bug@nro.ca.
4032 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4033 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4035 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4036 Mention more problems with the -e option.
4038 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4040 * NEWS: Typo.
4041 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4043 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4044 in URLs to improve DVI formatted output (requires texinfo 4.6).
4045 (System Services, Systemology, Shellology): Likewise.
4046 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4047 output.
4049 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4050 continuous text.
4051 (Runtime): Fix macro argument names to match description:
4052 `action-if-found' -> `action-if-true' and similarly.
4053 (Obsolete Macros): Likewise.
4054 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4055 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4056 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4058 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4060 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4062 * ChangeLog: Typo.
4063 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
4064 DVI output.

4077 (Floating Point Portability, Exiting Portably): New sections.
4078 (Writing Test Programs): Fix some langauge. Recommend exiting
4079 with status 1, not merely nonzero. Clarify exit declaration.
4080 (Run Time): Move C exit status stuff to new Exiting Portably section.
4081 (Systemology): Mention Posix and levenez. Update v7 reference.
4082 (Portable Shell): Mention the Posix shell.
4084 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4086 * bin/autoconf.as (me): Replace by as_me.
4088 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4090 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4091 since as_me isn't set yet.
4093 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4095 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix

4135 (Defining Directories): Likewise
4136 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4138 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4140 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4141 newline from the `trap' code to finish `config.log'; the NetBSD
4142 /bin/sh resets the exit status after an empty command, as
4143 documented in doc/autoconf.texi.
4144 Reported by Dalibor Topic <robilad@kaffe.org>.
4146 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4148 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4149 Suggested by Bruno Haible.
4151 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4153 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4154 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4155 Instead, just list the shells that we know work.
4156 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4157 changed. Be more cautious about the _cv_ variable.
4158 * tests/tools.at (Syntax of the shell scripts): Check the
4159 _cv_ variable once, at first, to avoid an internal autoconf error
4160 when sh -n does not work.
4162 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4164 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4166 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4168 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4169 use ">&-" since we're only 99.999% sure that this is portable,
4170 and since the MinGW bug is fixed in a different way.
4171 * lib/autotest/general.m4 (AT_INIT): Likewise.
4173 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4175 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4176 before opening config.log, to avoid hitting a bug on MinGW.
4178 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4180 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4181 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4182 This works around a MinGW bug reported by Eric Paire.
4183 Make sure that all writes to the log file append to it,
4184 rather than possibly losing data.
4185 * lib/autotest/general.m4 (AT_INIT): Likewise.
4187 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4189 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4190 description.
4192 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4194 * NEWS: Update.
4196 * configure.ac (AC_INIT): Bump to 2.59d.
4198 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4200 Version 2.59c.
4202 * Makefile.maint (news-date-check): Do not require a leading `*'
4203 before the release date in NEWS.
4205 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4206 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4208 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4209 the instantiated file do not contain the string 'datarootdir'
4210 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4211 @mandir@, replace the reference '${datarootdir}' by the value.
4212 * tests/torture.at (datarootdir workaround): New test.
4213 * NEWS: Advertise this temporary fixup.
4214 Based on a patch by Bruno Haible, reported and analyzed by
4215 Paul Eggert and Noah Misch.
4217 2006-04-12 Eric Blake <ebb9@byu.net>
4219 * tests/autotest.at (Debugging a failed test): Fix comment.
4221 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4223 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4224 all the changes since 2006-04-07.
4226 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4228 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4229 succeeded, but `ln -s file dir' failed, take care to remove the
4230 leftover target before the next test, to prevent its spurious
4231 failure; also make sure `ln file dir' works before selecting it.
4232 Thanks to Keith Marshall for pointing this out.
4233 * THANKS: Update.
4235 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4236 assignments in `at_debug_args', so that we put them correctly
4237 in the `run' script.
4238 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4239 Reported by Eric Blake.
4241 2006-04-11 Eric Blake <ebb9@byu.net>
4243 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4244 top-level tests after micro-suite has been run. Used in...
4245 (Debugging a successful test, Debugging script and environment),
4246 (Debugging a failed test): ...these new tests. The first of these
4247 is fixed by...
4248 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4249 macro, split out from...
4250 (AT_INIT): ...here, so that using -d also generates a run script.
4251 Document that -d inhibits top-level logging.
4252 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4253 inhibits top-level logging; debug scripts are created.
4255 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4256 check.
4257 * tests/autotest.at (Empty test, Empty check): New test to check it.
4259 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4260 from gcc.
4262 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4264 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4265 the files if a problem appears. Make the empty *.at files
4266 read-only, too. Proposed by Ralf Wildenhues.
4268 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4270 * config/Makefile.am: Add comment to force updated Makefile.in.
4272 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4273 space only patch to this file, this patch causes the Makefile.in
4274 files that include freeze.mk to be updated, and thus have a
4275 newer time stamp again, which in turn makes a pristine CVS
4276 checkout have correct time stamps.
4278 * Makefile.maint (cvs-sv): New macro, to be used..
4279 (config.guess-url_prefix, config.sub-url_prefix)
4280 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4281 point to CVS text checkout of Gnulib files.
4282 (copyright-check): Bump current year.
4283 (announcement): Do not hard-wire `./announce-gen'.
4284 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4285 correctly.
4286 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4287 `chmod +x'.
4288 (wget_files): Update config.guess, config.sub, texinfo.tex by
4289 `wget-update', now that their URLs work again.
4291 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4293 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4294 Problem noted by Paul D. Smith.
4296 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4298 * doc/autoconf.texi: Remove unused words from word list.
4299 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4300 .x-sc_trailing_space: New files.
4302 * doc/standards.texi: Sync from gnulib.
4304 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4305 `LIBOBJDIR' as experimental.
4307 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4308 with a target directory; it's internally implemented as `cp'
4309 anyway, but since Autoconf advertises the possibility to use
4310 a target directory when LN_S is `ln -s', we need to find out.
4311 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4312 analyzed by Keith Marshall <keith.marshall@total.com>.
4314 * THANKS: Update.
4316 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4318 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4319 confdefs.h as-is. In general, if it has backslash-newline or the
4320 like, then it doesn't work either to sort or to remove empty
4321 lines.
4323 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4325 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4327 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4329 * lib/autom4te.in (Automake-preselections): Preselect
4330 _AM_SUBST_NOTMAKE.
4332 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4334 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4335 apostrophe within a single-quoted string, as this is the usual
4336 tradition and is easier to read than '"'"'. Don't rely on the
4337 shell treating "$/" like '$/'. Use a more-consistent indenting
4338 style for the trap.
4340 2006-04-09 Eric Blake <ebb9@byu.net>
4342 * tests/autotest.at (Backquote command substitution),
4343 (Multiline backquote command substitution): Remove mistaken
4344 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4345 applied...
4346 (Parenthetical command substitution, Multiline parenthetical
4347 command substitution): here.
4349 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4351 Import macros from gnulib (often changing their name).

4365 (Pointers): Add Gnulib URL.
4366 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
4367 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
4368 Gnulib section.
4369 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

4371 Gnulib rather than trying to substitute stdbool code.
4372 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
4373 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
4374 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

4377 headers too.
4378 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
4379 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
4380 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
4381 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
4382 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4383 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4384 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
4385 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
4386 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
4387 (Coding Style). Don't mention m4_expand_once.
4388 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
4389 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
4390 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
4391 (AC_CHECK_FUNCS): Use it.
4392 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.

4395 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
4396 (AC_HEADER_ASSERT): New macro.
4397 (AC_HEADER_STDBOOL): Don't assume "#error" works.
4398 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
4399 Catch a bug in an HP-UX C compiler.
4400 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
4401 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
4402 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
4403 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
4404 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
4405 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
4406 New macros.
4408 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
4409 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
4411 2006-04-08 Stepan Kasal <kasal@ucw.cz>
4413 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4414 of the warning introduced by the 2001-08-28 change.
4416 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
4417 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4419 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
4420 variables shall be overriden by the cache.
4421 * tests/torture.at (AC_ARG_VAR): Test also with a first value
4422 that contains braces.
4424 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4426 Revert the patch from 2006-04-01 and only improve
4427 _AS_DETECT_BETTER_SHELL:
4429 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4430 skip nonexistent directories.
4431 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4432 only shell candidates which exist.
4433 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4434 * lib/autotest/general.m4 (AT_INIT): No need to give three
4435 parameters to _AS_PATH_WALK.
4437 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4438 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4440 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4441 distinguish m4sugar macros.
4442 * tests/tools.at (autoupdating with aclocal and m4_include):
4443 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4444 test case by Noah Misch <noah@cs.caltech.edu>.
4446 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4448 Revert my change from 2006-03-17, in other words:
4449 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
4450 and DUALCASE=1.
4451 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
4452 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
4453 it is set.
4455 2006-04-07 Eric Blake <ebb9@byu.net>
4457 * doc/autoconf.texi (Programming in M4sh): Document that
4458 AS_MKDIR_P exits the script on failure.
4459 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4461 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4463 * config/elisp-comp, config/install-sh, config/mdate-sh,
4464 config/missing, config/mkinstalldirs: Sync from Automake.
4466 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
4467 from Automake.
4469 * doc/make-stds.texi: Sync from gnulib.

4473 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4474 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4475 2006-04-01.
4477 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
4478 Eric Blake <ebb9@byu.net>,
4479 Paul Eggert <eggert@cs.ucla.edu>,
4480 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4482 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4483 whether `set' quotes correctly: redirect stderr of the tested
4484 `set', and use a subshell, for Ultrix; use `sed' instead of
4485 `grep' for zsh `set' which may write binary output; match only
4486 at the beginning of a line, to avoid false positives.
4487 In order to avoid false positives by unrelated variables with
4488 multiline content, put the dump algorithm in a subshell and
4489 unset all variables containing newlines (except some which are
4490 special to the shell). Warn about cache variables that are
4491 unset.
4493 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4495 * config/config.guess, config/config.sub, config/texinfo.tex:
4496 Sync from upstream.
4498 * tests/mktests.sh: Reword comments.
4500 * tests/mktests.sh: Only skip internal macros starting with
4501 `_AC_' or `__AC_'. Noted by Stepan Kasal.
4502 Update exclusion lists for the test suite to this end:
4503 (AC_ARG_VAR): Do test this now.
4504 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
4505 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
4506 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
4507 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
4509 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
4510 shell issue with double-quoted command substitutions of native
4511 commands.
4512 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
4513 Marshall.
4515 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
4516 no file matches the glob, discard the warning, set `nullglob'.
4517 (syntax-check): Likewise.
4518 (sc_cast_of_x_alloc_return_value): Likewise.
4519 (sc_cast_of_alloca_return_value, sc_error_exit_success)

4521 (m4-check): Likewise.
4522 (sc_system_h_headers): Do not print rule on execution.
4523 (sc_tight_scope): Do not fail for non-existing `src' directory.
4524 (sc_changelog): Skip the Copyright footer.
4525 * lib/autoconf/lang.m4: Remove trailing space.
4527 * lib/autoconf/status.m4: More replacements to
4528 <tab><space> where this makes sense.
4530 2006-04-06 Stepan Kasal <kasal@ucw.cz>
4532 * tests/Makefile.am (maintainer-check-posix):
4533 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4535 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4536 ac_config_<foo>s again, sometimes normalized, sometimes not.
4537 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4538 (AC_CONFIG_COMMANDS): Do not do so here.
4539 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4540 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4541 2005-07-25 rewrite. Noticed by Noah Misch.
4543 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4544 _AC_PRESERVE_HELP_ORDER, ...
4545 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
4547 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
4548 inside m4_expand_once; it is redundant.
4550 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
4551 for --help from Cygnus `configure.'
4553 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
4555 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
4556 on a patch proposed by Ralf Wildenhues.
4558 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4560 * lib/autoconf/status.m4: Replace <space>''<tab> with
4561 <tab><space> where this makes sense.
4563 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
4564 Noah Misch <noah@cs.caltech.edu>
4566 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
4567 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
4568 * doc/autoconf.texi (Help Formatting): New node.
4569 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
4571 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4573 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
4574 lib/autoconf/specific.m4, lib/autoconf/status.m4,
4575 lib/autoconf/types.m4, lib/autotest/general.m4,
4576 tests/mktests.sh, tests/torture.at: White space cleanup:
4577 remove some SPACE before TAB, or add quoting ('' or @&t@).
4579 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
4581 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
4583 2006-04-05 Eric Blake <ebb9@byu.net>
4585 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
4586 empty test suite works.
4587 * tests/autotest.at (Empty test suite): Remove xfail.
4589 2006-04-05 Noah Misch <noah@cs.caltech.edu>
4591 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
4592 TAGS to ac_config_<foo>s.
4593 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
4594 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
4595 normalizing it, consistent it with previous releases.

4603 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
4605 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
4606 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4607 Use 'comm' rather than N instances of grep; this also fixes a bug
4608 whereby substrings were incorrectly matched, causing us to not
4609 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4610 (exclude_list): Exclude empty macros.
4611 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

4616 Switch from grep to awk syntax.
4617 (ac_exclude_script): Renamed from ac_exclude_egrep.
4618 (au_exclude_script): Renamed from au_exclude_egrep.
4620 2006-04-04 Noah Misch <noah@cs.caltech.edu>

4638 typedef'ed restricted pointer, to catch a compiler bug on
4639 HP-UX 11.x, and fix warnings so it passes with -Werror.
4640 (_AC_PROG_CC_C99): Likewise.
4641 Reported by Albert Chin <china@thewrittenword.com>.

4661 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
4662 to log, point to testsuite output tree.

4692 Clean up _AC_COMPILER_EXEEXT* macros.
4694 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4695 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4696 ac_file to the name of the default output file and call
4697 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4698 initial `rm' of the candidate files...
4699 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4700 the same list in subsequent `rm' calls, and for the temporary
4701 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4702 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4703 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4704 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4705 no longer needed) by libtool. Make it a cache check.
4706 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4707 copied here by mistake.
4708 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4709 _AC_COMPILER_EXEEXT.
4710 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4711 _AC_COMPILER_OBJEXT directly.

4743 Autoconf version number despite a zero- or one-argument AC_INIT.
4745 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
4746 subordinate tools.
4747 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
4748 * doc/autoconf.texi (autoreconf Invocation): Document it.
4750 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

4762 the correct lines of the input file by subtracting..
4763 (_au__first_line): ..this new definition.
4765 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
4766 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
4767 Remove stray newline in output.
4768 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also

4779 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
4780 Kristian Kvilekval <kris@cs.ucsb.edu>.
4782 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4784 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4785 switch all of them on and of when necessary. Fixes the bug when
4786 m4sugar macros (e.g., m4_define) were expanded after the first
4787 automatic update (e.g., after AC_PREREQ or AC_INIT).
4789 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>
4791 * doc/autoconf.texi (Programming in M4sh): Sharpen the descriptions

4820 (File System Conventions): Put discussion of // versus / here, and
4821 modernize it a bit.

4836 * bin/autoscan.in: The value of find_configure_ac should be
4837 checked for existence, so we don't barf over a nonexisting
4838 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
4840 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4903 that the same works when cross-compiling.
4904 * tests/semantics.at (AC_CHECK_ALIGNOF, AC_CHECK_ALIGNOF struct):
4905 (AC_CHECK_SIZEOF, AC_CHECK_SIZEOF struct): Use it.

4983 nor C89 mode, set `$ac_cv_prog_cc_stdc' to `no' instead of
4984 trying to execute the command `no'.
4986 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not
4987 m4_define, so that the requirements of `AC_INCLUDES_DEFAULT' are
4988 expanded outside.

5022 the obsolescent AC_HEADER_STDC.
5023 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

5498 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
5500 2005-10-04 Stepan Kasal <kasal@ucw.cz>
5502 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
5503 before removing it (chmod -R u+rwx); there are three instances of this.
5505 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5506 Stepan Kasal <kasal@ucw.cz>
5508 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5509 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5510 make its content writable before removing it. Remove an errorneous
5511 comment from the end, where the logs of the failed tests are copied
5512 to the main log file.
5514 2005-09-27 Stepan Kasal <kasal@ucw.cz>
5516 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
5517 in case the computer is too quick. Double quote the configure.ac
5518 snippets.
5520 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
5521 problems if the testsuite were running too fast.
5523 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5525 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5526 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5527 (which belong to Xt, not X itself). See Debian bug 327655.
5528 * NEWS: Mention this.
5530 2005-09-07 Stepan Kasal <kasal@ucw.cz>
5532 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
5534 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
5536 * config/move-if-change: Don't output "$2 is unchanged";
5537 suggested by Ben Elliston. Handle weird characters correctly.
5539 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5541 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5542 calls, so that the final expansion of this macro is shorter.
5543 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5544 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5545 the cleanup there. Use AS_VAR_* macros, to be more general.
5546 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5548 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5550 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
5552 2005-09-01 Stepan Kasal <kasal@ucw.cz>
5554 * doc/autoconf.texi (Configuration Headers): Add an index entry
5555 for AH_HEADER.
5557 2005-08-26 Pavel Roskin <proski@gnu.org>
5559 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
5560 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
5561 running xmkmf.
5563 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
5565 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5566 The previous patch didn't work, so try a better one.
5568 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5570 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5571 in the example. Reported by Bruno Haible.
5572 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5573 "if $undefined_var;" succeeds with my shell.
5575 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5576 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5577 but change the m4_divert_text to m4_divert_once.
5579 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5581 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5582 Work around bug in Solaris /usr/xpg4/bin/awk.
5583 The bug is present in at least Solaris 8 through 10.
5585 2005-08-24 Stepan Kasal <kasal@ucw.cz>
5587 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5588 some evil values and relying on the fact that $* concatenates the
5589 parameters by the first character from IFS.
5591 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5592 Stepan Kasal <kasal@ucw.cz>
5594 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
5595 first header appears, define AH_HEADER.
5596 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
5597 Update limitations about when to call AC_CONFIG_HEADERS.
5598 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5599 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5600 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5601 ``Configuration Actions''; fix their index entries.
5603 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5604 options correctly. Process N-M as M-N if M is smaller than N.
5605 Process ranges correctly so that N-N will run only N.
5606 Sort and uniquify the tests that will be run. If there is more
5607 than one test, reinsert the banners for the tests.
5608 * tests/autotest.at (Keywords): Unmark XFAIL.
5610 2005-08-23 Stepan Kasal <kasal@ucw.cz>
5612 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
5613 before passing the macro name to AH_TEMPLATE.
5615 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5616 now opens log after option processing; in particular, --version
5617 and --help do not touch config.log.
5619 * Makefile.maint: Revert the change from 2005-08-12.
5621 2005-08-22 Stepan Kasal <kasal@ucw.cz>
5623 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
5624 common code to...
5625 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
5627 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5629 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
5630 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
5631 Language cleanup.
5633 * doc/autoconf.texi (Defining Symbols, Changed Results):
5634 Prepend to LIBS, not append, in examples.
5636 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5638 When building in place, set srcdir="."; suggested by Tim Van Holder.
5640 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5641 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5642 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5643 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
5644 does not mean "no --srcdir option".
5646 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5648 * tests/autoscan.at (autoscan): New file.
5649 * tests/suite.at: Use it.

5651 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
5653 * tests/autotest.at (Keywords): Test keywords combinations.
5655 2005-08-12 Stepan Kasal <kasal@ucw.cz>
5657 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
5658 add "2>&1"; gzip 1.2.4 prints help on stderr.
5660 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5662 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
5663 was pushdef'ed twice while popped only once. Push it only once.
5664 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
5666 2005-07-26 Stepan Kasal <kasal@ucw.cz>
5668 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
5669 prefixed by mere "===", not "configure: === ".

5673 * Makefile.maint: Update from Bison.
5675 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5676 "<tab>" in comment, so that the point is understandable.
5678 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5680 Rewrite substantial part of lib/autoconf/status.m4.
5681 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5682 and CONFIG_COMMANDS are not processed in four separate loops.
5683 Instead, there is one main loop. This alows that the common code
5684 is expanded only once, thus config.status (and configure) is smaller.
5686 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5687 the AC_LIST_FILES and cousins macros are no longer used.
5689 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5690 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5691 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5692 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5693 contain the initialization, nor the for loop, nor the associated
5694 commands; all these go to ...
5695 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5696 _AC_OUTPUT_CONFIG_STATUS.
5697 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5698 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5699 (_AC_OUTPUT_FILE): The creation of the sed script ...
5700 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5701 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5702 _AC_OUTPUT_MAIN_LOOP.
5703 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5704 _AC_CONFIG_COMMANDS): Use ...
5705 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5706 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5707 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5708 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5709 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5710 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5711 ... new macros.
5712 (_AC_CONFIG_UNIQUE): Update.
5713 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5714 Replaced by this ...
5715 (_AC_LIST_TAGS): ... new common macro.
5716 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5717 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5718 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5719 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5720 this didn't belong to the `config commands' section.
5721 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5722 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5723 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5724 to the `config commands' section either.
5725 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5726 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5728 ... and many changes to the comments nearby.
5730 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5731 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5732 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5733 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5734 (#define header templates): The comment at the top of the generated
5735 header now includes the name(s) of the source file(s).
5737 Several unrelated small changes:
5739 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5740 parameter to AC_DIAGNOSE.
5741 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5742 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5743 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5744 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5745 with AU::AC_OUTPUT.
5746 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5747 in AC_OUTPUT doesn't double-quote it either.
5748 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5749 parameters.
5751 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5753 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5754 versions of Portland Group compiler produce single- and double-quoted
5755 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5756 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5758 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5760 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5761 This is a corrected version of yesterday's patch.
5763 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5765 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5766 path, too; insert a "===" to emphasize the line.
5768 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5769 ac_cv_build_alias to ac_build_alias.
5770 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5772 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5773 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5774 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5775 (AC_ARG_VAR): ... here.
5776 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5777 target_alias.
5779 Keep a list of all precious variables and process them with one simple
5780 for loop, instead of expanding all commands, or, OTOH, complicated
5781 processing of output of "set".
5782 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5783 variable names in new macro...
5784 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5785 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5786 a loop to assign all ac_env_* and ac_cv_env_* variables.
5787 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5788 to INIT_PREPARE.
5789 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5790 its value to shell variable ac_precious_vars and call
5791 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5792 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5793 _AC_ARG_VAR_VALIDATE.
5795 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5796 and the AC_SUBSTs ...
5797 (AC_INIT): ... here.
5799 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5800 the ac_subst_files section in config.log.
5802 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
5804 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
5806 * NEWS: New macro AC_C_TYPEOF.

5811 Fix problems reported by Nicolas Joly.
5812 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5813 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5814 They are generated by the Tru64 v5.1B shell.
5816 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5818 Fix my changes from 2005-07-01; reported by Noah Misch.
5819 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5820 description, the macro now accepts only a single tag.
5821 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5823 Fix cases when the varsions of Autoconf and Autotest don't match.
5824 Reported by Noah Misch.
5825 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5826 at_top_builddir, for compatibility with older autotest.
5827 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5828 is not set, use at_top_builddir, for compatibility with older
5829 versions of autoconf.
5831 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5833 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5834 Problem reported by Patrick Welche.
5836 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5838 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5839 sed substitution command, so that we allow | in program prefixes
5840 and program suffixes. (& is a problem anyway; we're not fixing
5841 that here.)
5842 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5843 configure_input, top_builddir, srcdir, etc.
5844 * lib/autotest/general.m4 (AT_INIT): Likewise, for
5845 PATH_SEPARATOR in AUTOTEST_PATH.
5847 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5849 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5850 for loop over config.site files using `set', to allow
5851 directory names containing IFS characters.
5853 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
5855 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5856 directories with weird names. Apparently some people like living
5857 on the edge. However, improve the test that "pwd" actually does
5858 report a name for the working directory.
5859 * NEWS: Remove the claim that we test for funny chars in dir names.
5861 2005-07-01 Stepan Kasal <kasal@ucw.cz>
5863 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

5873 about #include <config.h>.
5874 (Generic Functions): Mention the Gnulib project.
5875 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
5877 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5878 document to output the default config_* lists to config.status.
5879 Don't recognize option --file, if the functionality is not there.
5880 Likewise for --header; moreover, recognize --he and --h as shortcuts
5881 for --help in that case.
5883 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5884 matches the order of execution. No code changed.
5886 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5888 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
5889 single-quoted -cmdline argument in Portland Group compiler.

5903 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
5905 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
5906 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5907 (AC_SUBST): Call it.
5908 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5909 the directory specific variables; but don't call it for configure_input.
5911 2005-06-28 Derek Price <derek@ximbiot.com>
5913 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5914 addition.
5916 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5918 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5919 directory have inherent problems with special characters like spaces,
5920 due to limitations in Make syntax. Problem reported by Alexandre
5921 Duret-Lutz.
5922 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
5923 Also, fix Tru64 porting problem with shell patterns,

5932 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
5934 Fix some more shell quoting problems. Prompted by a bug report
5935 from Justace Clutter.
5936 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
5937 variable into diagnostic. Make the diagnostic an error, not a warning,
5938 because we really don't support spaces and suchlike in dir names.
5939 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5940 Don't worry about backslashes in srcdir; it can't happen now.
5941 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
5942 Simplify ac_optarg handling.
5943 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
5945 2005-06-22 Stepan Kasal <kasal@ucw.cz>

5971 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5973 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5974 expand to the empty list. Don't use two pairs of m4_changequote,
5975 it's not necessary.

5984 * doc/autoconf.texi:
5985 Don't mention Solaris versions so much, if a
5986 problem is common to all extant versions of Solaris. Say "SunOS
5987 4" instead of "SunOS" for SunOS 4.
5988 (awk): Mention more of the limitations of traditional Awk.

6033 Problem reported by Ralf Menzel.
6035 2005-06-08 Derek Price <derek@ximbiot.com>
6037 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6038 renaming them since they are about to be redefined anyhow.
6040 2005-06-08 Derek Price <derek@ximbiot.com>
6042 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6043 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6044 Move m4_undefine to alphabetical order.
6046 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
6048 * README: Recommend GNU M4 1.4.3 or later.
6049 * doc/autoconf.texi (Introduction): Likewise.
6050 Reword to avoid some formatting glitches.

6053 Redo example output tp match current CVS snapshot.
6054 Use @example.org in email addresses when the examples
6055 might get inadvertently cut-and-pasted into user code.

6068 follows its own advice about quoting better.
6069 Reword to avoid some formatting glitches.
6070 * doc/installt.exi: Reword to avoid some formatting glitches.
6072 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6073 Tru64 ksh pattern matching bug. Reported against Libtool by
6074 Albert Chin <libtool@mlists.thewrittenword.com> and
6075 Nicolas Joly <njoly@pasteur.fr>.
6077 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6079 m4_cdr of one-member list was [[]] (one-member list containing an
6080 empty string) instead of [] (an empty list. Callers were skewed to
6081 match this misbehaviour. As a consequence of this:
6082 - m4_foreach([x], [], [foo]) expanded to `foo', while
6083 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6084 This bug has been fixed:
6086 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6087 expand to an empty string; print error msg if called without
6088 an argument list.
6089 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6090 misbehaviour; handle [] and [[]] correctly.

6098 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6100 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6101 swallow records with more than 99 fields.
6102 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6103 parse the long line.
6105 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6107 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6108 swallow literals longer than 399. Reported by Ralf Wildenhues.
6109 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

6116 checked (following the general autoconf preference for gcc).
6118 2005-06-03 Stepan Kasal <kasal@ucw.cz>
6120 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
6121 (DISTCLEANFILES): Remove $(check_SCRIPTS).
6122 (testsuite): Make sure autotest.m4f is up-to-date before using it.

6126 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6127 expression of unbounded size when processing the --list
6128 option. This runs afoul of a limit of 399 bytes per regular
6129 expression on AIX. Problem reported by Ralf Wildenhues.
6131 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

6137 give all the details about |#_!!_#|.
6138 Reword description of line replacement.
6140 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6142 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6143 now contain newlines, and substituted files must be referenced on
6144 a line alone; the sed scripts to substitute them are now very
6145 different.
6146 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6147 commands can be put in a sed script portably.
6148 * doc/autoconf.texi (Setting Output Variables): Document above
6149 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

6161 classes in shell scripts. The test was too brittle.
6163 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6165 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6166 * doc/autoconf.texi (Limitations of Builtins): Document this
6167 limitation.
6169 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6171 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6172 common code; used in many places in the tree.

6179 messages when ac_unique_file is not found.
6180 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6181 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6182 commands, for consistency with AC_MSG_ERROR and such.
6184 * bin/autoconf.as: Make more use of "shift 2" in option processing.

6196 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6197 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6198 (ac_top_builddir): ... this ...
6199 (ac_top_build_prefix): ... to this; the old name is also kept, for
6200 backward compatibility.
6201 (ac_top_builddir_sub): New variable, without the trailing slash,
6202 always nonempty.
6203 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6204 * doc/autoconf.texi (Configuration Actions): Rename

6215 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6217 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6218 argument to m4_foreach. I guess it was necessary in the past,
6219 but I think it's a no-op now.
6221 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6223 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6224 ``cat <<_ACEOF'' commands to one.
6225 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6226 * lib/autoconf/status.m4: On various places, use expr instead of
6227 ``echo|sed.''
6228 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6229 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

6231 a range.
6232 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

6238 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
6239 as on 2005-05-02.

6304 Also, throughout this document, be more careful about white space.
6305 "blank", "white space", and "space" all have different meanings
6306 and we should be careful to say what we mean.

6360 (m4_strip): Update the explanation.
6362 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6364 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

6396 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6398 * doc/autoconf.texi (Particular Functions): Use gnulib's current
6399 pattern for alloca snippet.
6401 2005-04-04 Stepan Kasal <kasal@ucw.cz>
6403 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

6409 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
6411 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6412 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6414 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6416 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6417 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6418 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6419 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6420 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6422 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6424 * NEWS: The configure command now warns you if you attempt to use
6425 a directory whose name contains a special character like space,
6426 newline, or "\".
6427 * doc/autoconf.texi (Installation Directory Variables): Allow
6428 "," in file names. Do not use \@; it's not a portable regexp.
6429 * bin/Makefile.am (edit): Likewise.
6430 * lib/Makefile.am (edit): Likewise.
6431 * tests/Makefile.am (edit): Likewise.
6432 * tests/semantics.at: Likewise.

6436 * doc/autoconf.texi (File System Conventions): Warn about
6437 unportable file names.
6438 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6439 (AC_INIT): Use it.
6440 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6441 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6442 ac_pwd, and quote srcdir.
6443 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6445 * doc/autoconf.texi: Fix some systematic formatting problems.
6446 ".)" needs a following @: if not at the end of a sentence, and
6447 similarly for "!)". "etc." should be preceded by a comma.
6448 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6450 2005-03-22 Bruno Haible <bruno@clisp.org>
6452 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6453 argument is often called 'build-aux'.
6455 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6457 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6458 macro AC_TRY_LINK is obsolete.
6459 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6460 `AC_CONFIG_FILES'.
6462 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6464 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6465 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6466 from a Common Lisp's `cl'.
6467 (AC_PROG_CXX): Behave according to the documentation: don't
6468 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6469 make the variable CCC precious; use `cl.exe', not `cl'.
6471 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6472 Alexandre Duret-Lutz <adl@gnu.org>
6474 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6475 /dev/null, as "configure" shouldn't read stdin, and this insulates
6476 us from problems (e.g., when testing for "cl"). Also, do this
6477 redirection before invoking "hostname" or "uname", and keep the
6478 original input stream available via...
6479 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6480 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6481 bother with "</dev/null" since it's now done at the top of
6482 'configure'.
6483 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6484 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

6490 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6492 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6493 newline if neither \c nor -n work, as that would output two
6494 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6496 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6498 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6499 This causes that any required macros inside will get before the if.
6500 * doc/autoconf.texi (autom4te.cache): A typo.
6502 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6504 Undo previous change, except keep the change to
6505 lib/autoconf/programs.m4 that replaced grep with shell
6506 pattern-matching. This is because net-snmp configure reads stdin.
6507 Reported by Noah Misch.
6509 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6511 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6512 from /dev/null, as "configure" shouldn't read stdin, and this
6513 insulates us from problems (e.g., when testing for "cl").
6514 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6515 before invoking "hostname" or "uname".
6516 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6517 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6518 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6519 "</dev/null" since it's now done at the top of 'configure'.
6520 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6521 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6522 Also, replace grep with shell pattern-matching, to save a process.
6524 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6526 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6527 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6528 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6529 compiler.
6531 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6533 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6534 grep -q isn't portable. Improve grep -s explanation.
6535 Problem reported by Dan Manthey.
6537 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6539 * doc/autoconf.texi (Special Shell Variables): Clarify
6540 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6542 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6544 * doc/autoconf.texi: Use @acronym for DJGPP.
6545 Fix some @code's that should have been @env's, and vice versa.
6546 Sort environment variable names.
6547 Mention that shells no longer inherit IFS.
6548 Don't recommend PATH_SEPARATOR=';' so strongly.
6549 Mention that $RANDOM might expand to the empty string.
6550 "symlink" and "soft link" -> "symbolic link".
6551 Improve mktemp description (reported by Bruno Haible).
6553 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6555 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6556 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6557 Likewise.
6558 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6559 Likewise.
6561 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6563 * NEWS: Mention AT_COPYRIGHT.
6565 * tests/local.at (AT_CMP): Use diff directly on input files rather
6566 than copying them.
6568 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6569 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6571 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6572 and Paul Eggert <eggert@cs.ucla.edu>
6574 * tests/autotest.at (Empty test suite): New test.

6579 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6581 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6582 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6583 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6584 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6585 (Standard regular expressions): New test.
6586 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6587 excess test name quoting.
6588 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6589 CPPFLAGS to `configure' instead of setting it in `configure'.
6591 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6592 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6593 on some platforms.
6595 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6596 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
6598 * tests/local.at (AT_CMP): New macro.
6599 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

6624 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
6626 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
6627 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6629 Try not to generated lines of unlimited length, as POSIX places a
6630 2047-byte limit on line length of portable text files.
6631 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6632 Use newline as a separator, not space.
6633 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
6634 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
6635 space.
6637 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6639 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
6640 as_func_*. Add test to check whether positional parameters
6641 are restored after function return.
6643 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
6645 * doc/autoconf.texi (Special Shell Variables): Mention _,
6646 BIN_SH, DUALCASE. Say that variables other than "status" are safe
6647 if they contain a lower-case letter. The DUALCASE problem was
6648 reported by Ralf Wildenhues.
6650 * bin/autoconf.as: Don't exit with status 0 after write failure
6651 with --help or --version.
6652 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

6658 Unicos 9 sed limitations.
6659 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
6660 to get the option-enhanced interface on older Crays. Try ftn for
6661 Fortran 95 (newer Crays).
6663 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
6665 * man/Makefile.am (.x.1): Go back to the simple solution, but take
6666 care to echo the commands, so the user knows what's going on.
6667 Modified from a suggestion by Stepan Kasal.
6669 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

6676 * doc/install.texi (Defining Variables): Likewise.
6677 Based on a proposed patch by Ralf Wildenhues.
6679 * man/Makefile.am (.x.1): Make sure the required generated files
6680 are up to date. Problem and original solution proposed by Stepan Kasal.
6681 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
6682 implicit-man-prerequisites): New rules, used by the above.

6688 2005-01-29 Stepan Kasal <kasal@ucw.cz>
6690 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6691 Update the long comment explaining it.
6693 m4_require no longer writes an ``is required by'' line to the
6694 execution stack. It contains only one bit of non-redundant
6695 information: that the macro was required, not called. And even
6696 this bit is useless in most situations: have you ever met a macro
6697 which both calls and requires the same macro?
6699 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6700 (_m4_defun_pro_outer): ... only via this macro, for the outermost
6701 macro.
6702 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
6703 (m4_expansion_stack_pop): Remove the misplaced comment.
6704 (m4_require): Don't put the ``is required by'' line to the
6705 execution stack; slightly improve the out-of-a-defun error message.
6706 (_m4_divert_grow): New macro, counter for the temporary diversions.
6707 (_m4_require_call): Use it.
6708 * tests/m4sugar.at (m4_require): Expect output without the
6709 ``is required by'' messages.
6711 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6713 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6714 rather than x for expr.
6716 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6717 this is safe.
6718 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6719 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6729 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
6730 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
6731 from masters, so that FileUtils.pm's update_file provide --force
6732 support.
6733 * bin/autoheader.in: Pass $force to update_file so that
6734 config.h.in is always recreated when --force.
6736 2005-01-24 Stepan Kasal <kasal@ucw.cz>
6738 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
6740 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6742 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6743 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6745 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6747 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6748 Warn about newline stripping in `` and $(). Update Solaris
6749 version to 9.
6750 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6751 X insulates us from future changes to Posix.
6752 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6753 stripping.
6755 2005-01-19 Stepan Kasal <kasal@ucw.cz>
6757 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
6758 you cannot use AC_DEFINE to define macros containing `[' or `]'.
6760 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
6762 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
6763 in Solaris 8 join. Problem reported by Tomohiro Suzuki on

6773 ulongval to be static, to avoid unwanted GCC warning. Problem
6774 reported by Michael Jennings via Daniel Reed; see
6775 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6777 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6779 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
6780 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
6781 datadir, infodir, and mandir. Adjust argument parsing code.
6782 (_AC_INIT_HELP): Update help text.

6784 new variables.
6786 2005-01-04 Noah Misch <noah@cs.caltech.edu>
6788 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
6789 not seem to work, assume it does set $(MAKE).
6790 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
6792 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6794 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
6796 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6798 A cleanup of the diversion support in m4sugar.
6800 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
6801 (_m4_divert_n_stack): New macro; the expansion is
6802 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
6803 otherwise.
6804 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6805 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6806 stored in _m4_divert_diversion or _m4_divert_dump.
6807 (m4_divert_pop): When the parameter is given, compare the symbolic
6808 name with the last diversion pushed on the stack. Previously, the
6809 current diversion was compared with the numeric value of the
6810 diversion given as the parameter.
6811 (m4_require): If the macro hasn't been expanded yet, call ...
6812 (_m4_require_call): this new macro.
6814 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6816 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

6830 Patch from Roger Leigh (with some minor changes) as follows:
6831 * NEWS: New macros AC_PROG_CC_C89, AC_PROG_CC_C99.
6832 Resurrect AC_PROG_CC_STDC.
6833 * doc/autoconf.texi (C Compiler): Add AC_PROG_CC_STDC,

7119 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

7238 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

7301 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7302 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7303 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7304 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7306 More fixes to support spaces in the name of the build directory.
7307 This isn't a complete fix but it's an improvement.
7309 * bin/autoconf.as (autom4te_options): New var.
7310 Use it instead of appending to AUTOM4TE, so that we can allow
7311 spaces in the build directory's absolute name.
7312 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7313 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
7314 AT_CHECK_NOESCAPE): Likewise.
7315 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
7316 main program): Likewise.
7318 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
7320 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
7321 From Ralf Corsepius in:
7322 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
7324 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
7326 * doc/autoconf.texi (Function Portability): Document isinf and
7327 and isnan. From a suggestion by Kevin Ryde.
7329 * lib/Autom4te/General.pm (END): Return correct exit status even
7330 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7332 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7334 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7335 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7336 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7338 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7340 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7341 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7342 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7343 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7344 * lib/autom4te.in (Automake-preselections): Preselect
7345 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7347 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7349 * lib/autom4te.in (Automake-preselections): Preselect
7350 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7351 trace them.
7353 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7355 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7356 Tru64.
7357 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7358 Document problem with "`""`" in pdksh POSIX mode.
7360 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7362 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7363 with pdksh, too. Problem reported by Patrick Welche via
7364 Gary V. Vaughan.
7365 * doc/autoconf.texi (Shellology): Note that set -o posix is
7366 useful for pkdsh, too.
7368 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7370 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7371 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7372 Don't fail if ENV or BASH_ENV is readonly.
7373 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7374 etc. are read only. Problem reported by Ludovic Courtes.
7376 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7378 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7379 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7380 (trivial change)
7382 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7384 * doc/autoconf.texi (File System Conventions): Warn about
7385 names like "aux". Problem reported by Eric Blake.
7387 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7388 by zero instead of array size, so that we can use any arithmetic
7389 constant expression (instead of requiring an integer constant
7390 expression). This allows us to test expressions like DBL_MAX <
7391 LDBL_MAX, which didn't conform to the C standard using the old
7392 method.
7393 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7394 now that we can do floating-point tests at compile time.
7396 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7398 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7399 and LDBL_EPSILON, as the resulting expression isn't an
7400 integer constant expression and violates the C standard.
7401 Problem reported by Nelson H. F. Beebe. Also, check
7402 for "L" suffix, and check that long double doesn't have
7403 worse range or precision than double, that mixed-mode
7404 arithmetic doesn't generate a diagnostic, that double
7405 constants fit in long double.
7407 2004-06-03 Kevin Ryde <user42@zip.com.au>
7409 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7410 malloc(0) and realloc(NULL,size).
7412 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7413 Bob Proulx.
7415 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7417 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7418 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7419 by Jim Meyering.
7421 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7423 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7424 can be rewritten using if-then-else. Suggested by Bruno Haible.
7426 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7428 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7429 Problem reported by Stepan Kasal.
7431 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7433 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7434 change). Patch reported by Ralf Wildenhues in
7435 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7437 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7438 function F exists if the compiler and linker let you compile an
7439 expression like (F != 0). Recent versions of GCC optimize away
7440 the reference to F in that case, since every function address must
7441 be nonzero, so the link succeeds even if F does not exist.
7442 Problem reported by Manu in
7443 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7445 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7446 "Unix". Many uses changed.
7447 (Limitations of Builtins): Explain better why the ! command isn't
7448 portable.
7450 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7452 * lib/autom4te.in (Automake-preselections): Preselect
7453 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7455 2004-05-19 Kevin Ryde <user42@zip.com.au>
7457 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7458 referencing AC_FUNC_STRERROR_R.
7460 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7461 note pessimistic assumption when cross compiling.
7463 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7465 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7466 (until 2004) invoked subcommands with sh -e, contra POSIX.
7467 Reported by Kevin Ryde.
7469 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7471 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7472 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7473 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7474 `test -f " /usr/bin/grep"', which _always_ failed.
7475 (AC_PROG_SED): Ditto bogus PATH fix.
7476 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7477 requires that grep correctly supports _multiple_ `-e' options, rather
7478 than stating only that grep should accept `-e'.
7480 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7482 Port to C99, which requires that 'exit' be declared.
7484 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7485 to ensure that stdlib.h is included.
7486 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7487 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7488 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7489 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7490 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7491 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7492 when using 'exit' in a test; C99 requires that 'exit' be declared.
7494 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7496 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7497 now prefers 'grep' implementations that accept -e.
7498 (Limitations of Usual Tools): Describe problems of traditional
7499 egrep and fgrep with long input lines, and of traditional grep
7500 with -e.
7501 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7502 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7503 All callers changed. Append /usr/xpg4/bin to the PATH, for
7504 Solaris.
7505 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7506 the user with complaints about multiple -e options.
7507 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7508 Define it with AC_PROG_GREP.
7509 * configure.ac (AC_PROG_GREP): Add.
7510 * lib/freeze.mk (GREP): New macro.
7512 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7514 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7515 a possible candidate only after all others fail, rather than
7516 consulting it first. This improves backward compatibility by
7517 better reflecting the way shell selection occurred in previous
7518 versions of Autoconf, and should help to avoid triggering latent
7519 problems in other packages, such as the one in Automake where zsh
7520 is not handled robustly:
7521 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7522 Although it is not Autoconf's responsibility to work around
7523 problems in Automake, it nevertheless makes sense to avoid
7524 introducing unnecessary incompatibilites.
7526 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7527 Gary V. Vaughan <gary@gnu.org>
7529 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7530 how deeply nested we are when a suitable tool is found, set the
7531 ac_path_TOOL_found flag.
7532 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7533 nested we are in this macro. Break out of all 3 nested loops if
7534 ac_path_TOOL_found is set.
7536 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7538 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7539 of the _AS_PATH_WALK loop too if GNU flavor is found.
7541 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7543 * doc/autoconf.texi (Limitations of Make): Update documentation
7544 for `$<'. New entry `Long lines', based on a report from Simon
7545 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7546 paragraph about DJGPP, based on a mail from Richard Dawe.
7548 2004-04-20 Paul Eggert <eggert@twinsun.com>
7550 * tests/c.at (C keywords): Don't assume that GCC supports
7551 "restrict" and "inline", as sufficiently-old GCC versions do not
7552 (also, GCC configured to be in pedantic C89 mode does not).
7553 Problem reported by Sumit Pandya in:
7554 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7556 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7557 consider -g to work if it generates warnings when plain compiles
7558 don't. Problem reported by Braden McDaniel in:
7559 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7561 * doc/autoconf.texi (Slashes): New section, to document a problem
7562 reported by Jim Meyering in:
7563 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7565 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7566 linker output files before linking, to work around IRIX 6 linker bug.
7567 Problem reported by Rainer Orth in:
7568 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7570 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7572 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7573 best tool so far counter rely on the tool path variable name to
7574 avoid checks for one tool being affected by the results of running
7575 the length check on a previous tool.
7577 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7578 match expression argument, as different greps have different
7579 regular expression flavours.
7580 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7581 literals.
7582 (AC_PROG_EGREP): Pass 'EGREP$'.
7583 (AC_PROG_GREP): Pass 'GREP$'.
7585 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7587 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7588 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7590 2004-03-29 Paul Eggert <eggert@twinsun.com>
7592 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7593 Types, Specific Compiler Characteristics, System Services,
7594 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7595 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7596 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7597 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7598 Likewise.
7599 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7600 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7601 AC_TYPE_OFF_T): Likewise.
7602 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7603 Likewise.
7605 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7606 pacify libtool 1.5.2. Fix quoting problems in sed command.
7608 2004-03-28 Paul Eggert <eggert@twinsun.com>
7610 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7611 now defines HAVE_DECL_TZNAME if it is declared, when
7612 HAVE_STRUCT_TM_TM_ZONE is not defined.
7613 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7614 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7615 for HAVE_TZNAME.
7617 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7619 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7620 superfluous backslashing of quotes (") in sed expressions;
7621 thanks to Paul Eggert.
7623 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7625 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7626 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7627 H. F. Beebe for the bug report.
7629 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7631 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7632 quoted -cmdline argument in Portland Group compiler (bug
7633 reported by Jeffrey J. Barteet).
7635 2004-03-25 Kevin Ryde <user42@zip.com.au>
7637 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7638 (Run Time): ... here, where it's now mentioned.
7640 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7642 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7643 inherits from language Autoconf-without-aclocal-m4.
7644 (Customizing autom4te): Adjust example; the cache must now be
7645 disabled for language Autoconf-without-aclocal-m4.
7647 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7648 Nathanael Nerode <neroden@twcny.rr.com>
7650 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
7651 AC_CHECK_TOOLS): Warn if a cross-tool is found without
7652 a prefix.
7653 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7654 AC_CHECK_TARGET_TOOLS): New macros.
7655 * doc/autoconf.texi (Generic Programs): Document
7656 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
7657 AC_CHECK_TARGET_TOOLS, and warn for future changes
7658 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
7659 AC_CHECK_TOOLS.
7660 (Specifying Names): Document the reason for these future
7661 behavioral changes.
7662 * tests/mktests.sh: Do not generate tests for the
7663 new macros.
7664 * NEWS: Document these changes.
7666 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7667 they make TeX hang up.
7669 2004-03-15 Paul Eggert <eggert@bogus.example.com>
7671 * NEWS: New macro AC_CHECK_ALIGNOF.
7672 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7673 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7674 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7675 vowel.
7676 (AC_CHECK_ALIGNOF): New macro.
7677 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7678 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7679 those for sizeof.
7681 2004-03-03 Paul Eggert <eggert@twinsun.com>
7683 * bin/Makefile.am (edit): Don't use $< in a context where
7684 POSIX doesn't require support for it. Use $@.in instead.
7685 Problem reported by Anthony N. Frasso in
7686 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7687 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7689 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7691 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7692 from the next generation of Libtool.
7693 * lib/autom4te.in (Autoreconf-preselections): Ditto.
7695 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7697 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
7698 is not always thread-safe. Report from Nathanael Nerode.
7700 2004-02-18 Paul Eggert <eggert@twinsun.com>
7702 Fix a dependencies problem, stemming from a Autoconf 2.59 build
7703 problem on QNX reported by Stephen Rasku in
7704 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
7706 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
7707 $(m4sh_m4f_dependencies); this removes a FIXME.
7708 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
7709 (MAINTAINERCLEANFILES): Split into pieces,
7710 one per related section. Add $(srcdir)/wrapper.in.
7712 2004-02-09 Paul Eggert <eggert@twinsun.com>
7714 * doc/autoconf.texi (Setting Output Variables): Emphasize that
7715 AC_SUBST provides no portable way to escape literal newlines.
7717 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7718 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7719 Darwin uses -lcrt2.o and there's little point to cataloging all
7720 the system variants. Partial fix reported by Andreas Waechter in:
7721 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7722 for bug reported by Nelson H. F. Beebe in:
7723 http://mail.gnu.org/archive/html/bug-autoconf/2003-12/msg00090.html
7725 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
7727 * doc/autoconf.texi (AU_DEFUN): Fix English,
7728 suggested by Paul Eggert.
7729 * lib/autoconf/autoupdate.m4: Correct reference to
7730 acobsolete.m4, suggested by Alexandre Duret-Lutz.
7732 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
7734 * bin/autoupdate.in: Define __file__ so that warnings
7735 refer to the correct file.
7736 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7737 the behavior of the third argument.
7738 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7739 correctly the behavior of the third argument. Document
7740 what the three macros that AU_DEFUN defines do. Fix

7760 (AS_REQUIRE_SHELL_FN): Require shell functions when
7761 it is used.
7762 (_AS_LINENO_WORKS): Put around braces, we do not

7774 (AU_DEFUN): Honor the third parameter, create autoupdate
7775 macros with AU_DEFINE.
7776 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
7777 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

7796 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

7798 the 2003-05-22 change, which removed the older years from the list.
7799 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7801 2004-01-27 Gary V. Vaughan <gary@gnu.org>

7819 2004-01-27 Paul Eggert <eggert@twinsun.com>
7821 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

7823 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7824 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7826 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7827 bin/autoconf.in, config/Makefile.in, config/config.guess,
7828 config/config.sub, config/install-sh, config/mdate-sh,

7843 2004-01-26 Paul Eggert <eggert@twinsun.com>
7845 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7846 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7847 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7848 not <inttypes.h>. Problem reported by Tim Mooney in
7849 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7850 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7851 Likewise.
7853 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7854 otherwise "make check" fails because it forbids cmp (I guess
7855 because cmp treats files as binary on DOS-like systems).
7857 * tests/mktests.sh: Update copyright date to 2004, since some tests
7858 have changed in 2004.
7860 2004-01-23 Gary V. Vaughan <gary@gnu.org>

7863 non-truncating sed or gsed program in PATH.
7864 * tests/acprograms.at: Add it.
7865 * doc/autoconf.texi (Particular Programs): Document it.
7866 * NEWS: Updated.
7868 2004-01-15 Paul Eggert <eggert@twinsun.com>
7870 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7871 -std1 disables some useful extensions on Tru64. Problem reported
7872 by N. Lichtmaier in
7873 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7875 2004-01-14 Paul Eggert <eggert@twinsun.com>
7877 * doc/autoconf.texi (Programming in M4sh): Document that
7878 AS_MKDIR_P succeeds if the destination is a symbolic link
7879 to an existing directory.
7880 (Limitations of Usual Tools): Note that mkdir -p might not
7881 succeed on symlinks to directories.
7883 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7885 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7886 * bin/autoheader.in: Grammar fix in message.
7887 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7888 Test for dir before calling mkdir -p. (trivial changes)
7890 2004-01-13 Eric Blake <ebb9@byu.net>
7892 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7893 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7895 2004-01-10 Jim Meyering <jim@meyering.net>
7897 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7899 2004-01-09 Paul Eggert <eggert@twinsun.com>
7901 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7902 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7903 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7904 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7905 AC_COMPILE_IFELSE, since we now assume our caller invokes
7906 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7907 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7908 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7909 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7911 2004-01-07 Paul Eggert <eggert@twinsun.com>
7913 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7914 `"'...'"`, as it's confusing (and I suspect it may not work on
7915 some platforms). The code was incorrect anyway, as it assumed
7916 that \$ evaluated to itself in that context. Reported by
7917 Alexandre Duret-Lutz.
7919 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7921 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

7927 example, and add more examples. Reported by Eric Sunshine.
7929 2004-01-05 Paul Eggert <eggert@twinsun.com>
7931 * doc/autoconf.texi (Limitations of Usual Tools):
7932 Remove warning against "rm -fr" introduced yesterday; it
7933 was a false alarm.
7935 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7936 autoscan, autoupdate, ifnames): Don't use chmod -w.
7937 * lib/Makefile.am (autom4te.cfg): Likewise.
7938 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7939 "chmod -w".

7944 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
7945 by doing lineno substitution only on lines containing "$LINENO".
7947 2004-01-04 Paul Eggert <eggert@twinsun.com>
7949 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
7950 Use "rm -f" to remove conftest.sed, not plain "rm".
7951 Bug reported by David Relson in
7952 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
7954 * Makefile.am (autom4te-update):
7955 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
7956 * Makefile.maint (my-distcheck, do-po-update): Likewise.
7957 * doc/autoconf.texi (Guidelines): Likewise.
7958 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

7963 * tests/Makefile.am (clean-local): Likewise.
7964 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
7965 srcdir): Likewise.
7966 * doc/autoconf.texi (Limitations of Usual Tools):
7967 Warn against "rm -fr".
7969 2004-01-03 Paul Eggert <eggert@twinsun.com>
7971 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7972 -c -o might not work. From a suggestion by Kevin Ryde.
7973 (C Compiler, Generating Sources, Limitations
7974 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7975 Don't put '-o' after non-options, as POSIX doesn't allow this.
7976 Mention that cc's name might be gcc or c89 or whatever.
7978 2004-01-04 Kevin Ryde <user42@zip.com.au>
7980 * doc/autoconf.texi: Add various further index entries.
7982 2003-12-29 Paul Eggert <eggert@twinsun.com>
7984 * bin/autoreconf.in (autoreconf_current_directory):
7985 Fix typo: mkdir without umask arg.
7987 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7989 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7990 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
7991 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
7992 explanation clearer.
7994 2003-12-24 Andreas Schwab <schwab@suse.de>
7996 * doc/autoconf.texi (Default Includes): Fix misspelling of

8001 * configure.ac: Test if sh -n works.
8002 * configure: Regenerate.
8003 * tests/atlocal.in: Store the result here.
8004 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
8005 tools.at, looking in atlocal's ac_cv_sh_n_works instead
8006 of explicitly testing.
8007 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
8008 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
8009 * tests/tools.at (Syntax of the shell scripts): Simplify
8010 using AT_CHECK_SHELL_SYNTAX.

8023 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
8024 Extracted from AS_SHELL_SANITIZE.
8025 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
8026 macros.
8027 (AS_SHELL_SANITIZE): Move reinvocation code from
8028 _AS_LINENO_WORKS, use it to find out if shell
8029 functions work.
8030 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
8031 does not work.
8032 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
8033 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

8047 them on the fly.
8049 2003-11-24 Akim Demaille <akim@epita.fr>
8051 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

8079 parameter of AU_DEFUN.

8084 the expanded body, consistently with other macros such as AC_USG.
8086 2003-11-17 Paul Eggert <eggert@twinsun.com>
8088 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

8090 patch 3 reported by Eric Sunshine.
8092 2003-11-15 Kevin Ryde <user42@zip.com.au>
8094 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
8095 than $target since the latter is not usual, add guidelines on when to
8096 use or not use the system type.
8098 2003-11-12 Derek Price <derek@ximbiot.com>
8100 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
8101 typo misrepaired by an auto-spellcheck.
8103 2003-11-12 Akim Demaille <akim@epita.fr>

8173 * bin/autom4te.in (&freeze): Use a less likely warning separator
8174 than `\n\n', so that `\n\n\n' is valid in warnings.
8175 Reported by Steve Huston.
8177 2003-10-28 Akim Demaille <akim@epita.fr>
8179 * Makefile.cfg (local_updates, executable-update): Tweak to be

8255 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
8256 cross test.
8258 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
8260 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official

8271 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
8272 Issue a more-informative diagnostic.
8273 Problems reported by Eric Sunshine.
8275 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8277 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
8278 -mGLOB_options_string stuff for Intel ifc, which can cause

8298 -lcrt[01].o.
8300 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
8302 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8303 cache variable instead of $G77 to decide whether to include -O2,
8304 since $G77 is specific to Fortran 77.
8306 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8308 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
8309 free" flag. Re-order flags tested into rough order of popularity.
8311 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8313 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
8314 arguments so that it can be used with syntax identical to
8315 AC_PROG_F77, and so that we can more easily decide to
8316 remove/deprecate the DIALECT optional argument in the future if it
8317 proves troublesome.
8318 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
8319 non-freeform-supporting compilers. Document freeform flags.
8321 2003-10-03 Akim Demaille <akim@epita.fr>
8323 * configure.ac: Look for emacs, not macs.
8324 Reported by Eric Sunshine.
8326 2003-10-03 Akim Demaille <akim@epita.fr>
8328 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
8329 * bin/autoreconf.in (autoreconf_current_directory): Create the
8330 AUX_DIR if needed, for sake of automake --add-missing etc.
8331 Suggested by Alexandre Duret-Lutz.
8333 2003-10-03 Akim Demaille <akim@epita.fr>
8335 * configure.ac: Quotation and formatting changes.
8336 (EMACS): Don't set it if it is not recent enough to support

8358 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
8360 2003-09-30 Akim Demaille <akim@epita.fr>
8362 * config/announce-gen (&print_news_deltas): Extracted from...
8363 (&print_changelog_deltas): here.
8364 (&news_file): Rename as...
8365 (@news_file): this.

8382 Problem reported by Lars J. Aas in
8383 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
8384 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8385 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
8386 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
8388 2003-09-26 Akim Demaille <akim@epita.fr>
8390 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8391 directory for AC_CONFIG_COMMANDS' first argument exists.
8392 This makes valid the invocation of _AC_SRCPATH that follows.
8393 Reported by Eric Sunshine.
8394 * doc/autoconf.texi (Configuration Commands): Adjust.
8396 2003-09-26 Akim Demaille <akim@epita.fr>
8398 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
8399 Reported by Ralf Corsepius.
8401 2003-09-26 Akim Demaille <akim@epita.fr>
8403 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
8404 arguments.
8405 Actually, use AU_ALIAS.
8406 From Bruno Haible.
8408 2003-09-26 Paul Eggert <eggert@twinsun.com>
8410 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
8411 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

8415 2003-09-26 Akim Demaille <akim@epita.fr>
8417 The test suite are sometimes assigning timings incorrectly.
8418 Reported by Henk Krus.
8419 Diagnosed by Nicolas Joly.
8421 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8422 AT_help_all.
8423 Instead of making AT_help a sequence of assignments to grow
8424 $at_help_all, just make AT_help_all be the growing contents of
8425 $at_help_all, and make a single assignment in...
8426 (AT_INIT): here.
8427 (at_times_skip): Flip the meaning and rename as...
8428 (at_times_p): this.
8429 (AT_INIT): When summarizing the test that ran, remove
8430 $at_times_file after use, and check it is present before trying to
8431 use it.
8433 2003-09-25 Akim Demaille <akim@epita.fr>
8435 Version 2.57d.
8437 * bin/Makefile.am (edit): Handle '@configure_input@'.

8439 (ifnames): chmod -w.
8440 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8441 executables, not bin/ executables! Otherwise all the magic needed
8442 to find non installed files is turned off. This caused a failure
8443 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8444 as found in its environment (sent by tests/autoreconf): pointing
8445 to bin/autom4te that could not find its files.
8446 * tests/mktests.sh: Force the replacement of generated files, for
8447 the sake of "mv" program that are interactive when overwriting a
8448 -w file.
8449 * config/install-sh: Upgrade from CVS Automake.
8451 2003-09-23 Paul Eggert <eggert@twinsun.com>

8454 versus test -L issues.
8456 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
8457 Paul Eggert <eggert@twinsun.com>
8459 Trivial change to support GCC's configuration procedure.
8460 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
8461 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
8462 about inconsistency if the preprocessor is set to give errors for
8463 any warning.
8464 * doc/autoconf.texi (C Compiler Characteristics): Document this.
8466 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
8468 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
8469 and XFile.pm from Automake.

8484 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
8485 not asm/types.h.
8487 2003-09-11 Akim Demaille <akim@epita.fr>
8489 * doc/autoconf.texi (Header Portability): linux/random.h.
8490 From Peter Hendrickson.
8492 2003-09-10 Akim Demaille <akim@epita.fr>
8494 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8495 willing to edit the output files.
8497 2003-09-10 Akim Demaille <akim@epita.fr>
8499 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
8500 and AC_FC_FREEFORM.
8501 * tests/mktests.sh: Skip AC_FC_SRCEXT.
8502 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
8504 2003-09-09 Akim Demaille <akim@epita.fr>
8506 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
8507 Reported by Gary Vaughan.

8512 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
8513 trailing files.

8517 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
8518 Improve the accuracy of the wording about obsolescence.
8519 From a suggestion by Ian Lance Taylor in
8520 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8522 2003-09-05 Paul Eggert <eggert@twinsun.com>
8524 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8525 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8527 2003-09-04 Akim Demaille <akim@epita.fr>
8529 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8530 AC_FUNC_WAIT3.
8532 2003-09-04 Akim Demaille <akim@epita.fr>
8534 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8535 (freeze): When exiting, use $exit_code.
8536 * lib/autoconf/fortran.m4: Comment changes.
8538 2003-09-04 Akim Demaille <akim@epita.fr>
8540 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8542 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8544 Add support for newer Fortran dialects. The F77 interface is
8545 unchanged, and continues to support Fortran 77. New FC macros
8546 correspond to all the old F77 macros, with output variables FC,
8547 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8548 available dialect, but older dialects can be specified. There are
8549 new macros AC_FC_SRCEXT to set the source extension, and
8550 AC_FC_FREEFORM to accept free-form source files.
8552 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8553 New macros.
8554 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

8570 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8571 Rewrite in terms of the above.
8572 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8573 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

8579 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8580 Document problems with timestamp resolution that 'make', 'cp -p', and
8581 'touch -r' have.
8583 2003-08-27 Akim Demaille <akim@epita.fr>
8585 * tests/m4sugar.at (cross_warning): Make sure to enable the

8588 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8589 are defaulted by AT_CHECK anyway.
8590 Use AT_CHECK_AUTOM4TE.
8591 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8592 missing dnl.
8594 2003-08-27 Akim Demaille <akim@epita.fr>
8596 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8597 when -Wobsolete is set.

8674 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8676 2003-08-21 Akim Demaille <akim@epita.fr>
8678 First stab at preserving warnings between calls to autom4te,
8679 including when the cache is used.
8681 There are still several issues: (i) there are too many runs of m4
8682 (one for include, one for warnings, and some more), (ii) warnings
8683 spreading on several lines are not handled gracefully, (iii) the
8684 code meant to have the call stack display for errors does not work
8685 (its handling should move from m4 to autom4te).
8687 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8688 Use them.
8689 (@preselect): Add m4_warn.
8690 ($exit_status): Remove, use $exit_code.
8691 ($help): Use Autom4te::ChannelDefs::usage.
8692 (&handle_m4): No longer define the m4_warnings.
8693 At each run, extract and report the warnings.
8694 Always cache the result, including if the exit status is on
8695 failure, since if nothing changes, we should result in the same
8696 failure, hence we can use the cache.
8697 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8698 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8699 Remove.
8700 (m4_warn): Redefine as a do-nothing: it is its invocation that
8701 matters, as warnings are now reported via traces.
8702 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8703 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8704 the latter reveals calls to the former.
8706 Adjust the tests.
8708 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8710 2003-08-21 Akim Demaille <akim@epita.fr>
8712 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8713 Use them.
8715 2003-08-21 Akim Demaille <akim@epita.fr>
8717 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8718 forward order.
8719 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8720 (&parse_warnings): Accept a list of warning requests.
8721 (&usage): Return a string, not a side effect.
8722 (cross): New warning category.
8724 2003-08-21 Akim Demaille <akim@epita.fr>
8726 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8727 (&require_configure_ac): Accept an optional directory argument.
8728 ($configure_ac): Remove.
8729 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8730 (&catfile): Remove.
8731 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8732 * bin/autoscan.in: Adjust.
8734 2003-08-20 Akim Demaille <akim@epita.fr>
8736 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
8737 Reported by Alexandre Duret-Lutz.
8739 2003-08-20 Akim Demaille <akim@epita.fr>
8741 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
8742 * bin/autom4te: Adjust.
8743 In particular, be Autoconf tools are really silent when properly
8744 working, bind the verbosity of the 'note' channel to $verbose.
8745 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8746 (&xsystem, &contents): Remove, since they are exported by...
8747 * lib/Autom4te/FileUtils.pm: this.
8748 More perldoc.
8749 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
8750 * lib/Autom4te/FileUtils.pm: here.
8752 2003-08-20 Akim Demaille <akim@epita.fr>
8754 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
8755 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
8756 from CVS Automake.
8758 2003-08-20 Akim Demaille <akim@epita.fr>

8761 (autom4te-update): New.
8762 * Makefile.cfg (update): Bind autom4te-update.
8764 2003-08-19 Derek Price <derek@ximbiot.com>

8780 * lib/autom4te.in (Automake-preselections): Preselect
8781 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
8782 and m4_sinclude.
8784 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
8786 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

8807 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
8808 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8809 shorter column three. Add DESCRIPTION to log file content.
8811 2003-08-13 Derek Price <derek@ximbiot.com>
8813 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8814 output.
8816 2003-08-12 Derek Price <derek@ximbiot.com>
8818 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8819 (AT_CHECK_NOESCAPE): Move core functionality to...
8820 (_AT_CHECK): ...this new macro.
8822 2003-08-07 Derek Price <derek@ximbiot.com>
8824 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8825 (AT_CHECK_NOESCAPE): ...to this new macro.
8827 2003-07-31 Paul Eggert <eggert@twinsun.com>
8829 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8830 in Bash 2.01. Problem reported by Brian Gough in
8831 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8833 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8835 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8836 -lcrt1.o, for OS X. (trivial change)
8838 2003-07-07 Paul Eggert <eggert@twinsun.com>
8840 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8841 inside '#ifndef __cplusplus'. Problem reported by
8842 Bob Friesenhahn.
8844 2003-07-06 Bill Clarke <llib@computer.org>
8846 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8847 'long', not 'int', for benefit of Sun's recent C++ compilers
8848 (trivial change). See:
8849 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8850 (This really should be 'intptr_t', not 'long', but that would
8851 take more work.)
8853 2003-06-25 Akim Demaille <akim@epita.fr>
8855 * lib/Makefile.am (autom4te.cfg): Make it read only.
8856 Depend on Makefile since it contains substitutions.
8857 From Paolo Bonzini.

8859 This change was made on autom4te.cfg which is generated.
8860 Reported by Raja R. Harinath.
8862 2003-06-25 Akim Demaille <akim@epita.fr>
8864 * doc/autoconf.texi (Header Portability): sys/mount.h.
8865 From Gareth McCaughan.
8867 2003-06-23 Akim Demaille <akim@epita.fr>
8869 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8870 not all of them. This fixes 1. the fact that when testing
8871 Autoconf there are many many config.log, 2. the incorrect use of
8872 top_srcdir to find config.log.
8873 Don't mix the detailed output of failed test with the summary of
8874 failures. Rather, append detailed log afterwards.
8876 2003-06-23 Akim Demaille <akim@epita.fr>
8878 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8879 always run: output config.log on $at_group_log.
8881 2003-06-23 Akim Demaille <akim@epita.fr>
8883 * tests/torture.at (#define header templates): Don't use quotes in
8884 C++ comments as it puzzles Emacs' sh font-lock-mode.
8886 2003-06-23 Akim Demaille <akim@epita.fr>
8888 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8889 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8890 * tests/atspecific.m4: Rename as...

8893 * tests/local.at: here.
8894 * tests/Makefile.am: Adjust.
8895 * doc/autoconf.texi (testsuite Scripts): Adjust.
8897 2003-06-21 Kevin Ryde <user42@zip.com.au>
8899 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8900 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8901 ensuring we add -std1 for full-ANSI.
8903 * doc/autoconf.texi (hdrindex): New macro.
8904 Add index entries for portability of various standard header files.
8906 2003-06-20 Akim Demaille <akim@epita.fr>
8908 * configure.ac: Bump to 2.57b.
8910 2003-06-20 Akim Demaille <akim@epita.fr>
8912 Version 2.57a.
8914 2003-06-20 Akim Demaille <akim@epita.fr>
8916 * bin/autom4te.in: Don't rely on $HOME being defined.
8917 Reported by Marc Espie as PR/233.
8919 2003-06-20 Akim Demaille <akim@epita.fr>
8921 * lib/autotest/general.m4: Use at_times_file only if used.

8926 * config/config.guess, config/config.sub, config/elisp-comp,

8930 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8932 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8933 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8934 (TEST_SCRIPT): New diversion.
8935 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8936 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8937 (AT_INIT): Support for expected failures.
8939 2003-06-02 Akim Demaille <akim@epita.fr>
8941 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8942 changes.
8943 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8944 Autoconf nor Automake.
8945 (&contents): New, from Automake.
8946 PODify.
8948 2003-05-28 Paul Eggert <eggert@twinsun.com>
8950 * NEWS, doc/autoconf.texi (Particular Functions),
8951 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8952 is the inverse of localtime.
8954 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8956 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8957 (handle_exec_errors): New function. Work around $! being
8958 altered by WEXITSTATUS.
8959 (xqx, xsystem): Use handle_exec_errors.
8961 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8963 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8964 Do not call `_exit()', simply modify `$?'.
8965 (xsystem): Reset $! before running system, and check it afterward.
8966 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8967 63 for version mismatches.
8969 2003-05-23 Akim Demaille <akim@epita.fr>
8971 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8972 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8973 the middle of a line).
8974 * lib/m4sugar/m4sugar.m4: Likewise.
8975 Remove useless spaces in comments.
8977 2003-05-23 Akim Demaille <akim@epita.fr>
8979 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8980 exit 63, so that we (or Automake's "missing") can tell the
8981 difference with a plain failure.
8982 * doc/autoconf.texi (Notices): Adjust.
8984 2003-05-23 Akim Demaille <akim@epita.fr>
8986 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8987 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8988 White spaces cleanup.
8990 2003-05-22 Jim Meyering <jim@meyering.net>
8991 Paul Eggert <eggert@twinsun.com>
8993 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8994 Remove `#include <stdlib.h>' from the list; we should never
8995 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8996 resulting namespace pollution would cause other tests to fail.
8997 Configure scripts run with some older versions of g++ and HP's
8998 aCC would fail due to such an #include. Problems reported by
8999 Matthew Mueller in <http://bugs.debian.org/120704> and by
9000 Keith Bostic in
9001 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9002 In the test, use the test declaration before including <stdlib.h>,
9003 as that's closer to how it'll be used.
9005 2003-05-23 Akim Demaille <akim@epita.fr>
9007 * doc/autoconf.texi (Header Portability): ucred.h.
9008 From Ian Redfern.
9010 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9012 Overhaul Autotest's logging: generate separate log files
9013 in testsuite.dir/NNN/testsuite.log, and append them to
9014 testsuite.log instead of re-running the test verbosely.
9016 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9017 file descriptor, write 0 to at_status_file instead of setting
9018 at_status=0, initialize some new variables (at_status_file,
9019 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9020 to rerun the tests, instead append the at_group_log to the
9021 at_suite_log when a test fails.
9022 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9023 with the AS_MESSAGE_LOG_FD redirected to stdout.
9024 (AT_CLEANUP): save the output status in $at_status_file
9025 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9026 its original place.
9027 (AT_CHECK): since tests are run with a redirected stdout,
9028 and used to be re-run in verbose mode, turn some $at_verbose
9029 into echo, and don't redirect the output of testing stdout
9030 and stderr.
9032 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9033 the name of the debugging directory and information about
9034 its contents.
9036 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9038 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
9039 parameter.

9112 AC_INCLUDES_DEFAULT.
9114 2003-05-17 Akim Demaille <akim@epita.fr>
9116 * lib/autoconf/specific.m4: Include signal.h and unistd.h.

9118 Reported by Werner LEMBERG and Debian Bug 190886.
9120 2003-05-16 Akim Demaille <akim@epita.fr>
9122 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
9123 user name space clashes.
9124 Reported by Bruno Haible.
9126 2003-05-16 Akim Demaille <akim@epita.fr>
9128 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9129 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make

9131 Reported by Martin Mokrejs.

9151 and truncate.
9153 2003-05-06 Akim Demaille <akim@epita.fr>
9155 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9156 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9157 by aclocal.m4 is changed it might require the importing of another
9158 m4 extension file, i.e., aclocal must be run.
9160 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9161 (&parse_args): Use --force with aclocal if required and supported.

9169 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9170 argument instead of a file name, so that the request file remains
9171 open during the whole autom4te run.
9172 ($icache_file): New.
9173 (&freeze): Lock the $icache_file.
9175 2003-04-29 Derek Price <derek@ximbiot.com>
9177 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the

9179 (AT_CLEANUP): Add `;' to end of at_help_all.
9180 (AT_INIT): Allow --keywords to be specified more than once. When
9181 grepping $at_help_all for keywords, use the field and keyword
9182 seperators to ensure a complete keyword match. Alter at_prev handling
9183 to support the new --keywords behavior.
9185 2003-04-27 Karl Berry <karl@freefriends.org>
9187 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9188 align better with others. I also made some of the individual
9189 entries on one line, for brevity and to make it easier for me to

9286 obsolete AC_HELP_STRING.
9287 (AC_HELP_STRING): AU_DEFUN to...
9288 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
9289 * tests/m4sh.at (AS_HELP_STRING): New test.
9291 * tests/acgeneral.at: Regenerated.
9293 2003-03-26 Derek Price <derek@ximbiot.com>
9295 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
9296 sense. Verbosify the diversion definitions comment.

9334 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
9335 Tru64 make in the "target lookup" section.
9336 (Automake): Automake 1.5+ no longer requires special tools to be
9337 present on the developer's host.
9339 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
9341 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
9342 to a shell that can handle redirection or quoting correctly.

9346 * bin/autoreconf.in (BEGIN): Likewise.
9347 * bin/autoscan.in (BEGIN): Likewise.
9348 * bin/autoupdate.in (BEGIN): Likewise.

9353 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
9354 to cope with DOS-style absolute paths, when constructing
9355 ${ac_make}.
9357 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
9358 When constructing paths with IFS=:, quote the path. If we're
9359 constructing a DOS-style absolute path, we don't want to split it
9360 on the colon.
9362 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
9363 in description.
9365 2003-02-25 Pavel Roskin <proski@gnu.org>

9377 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
9378 to fix a mismatch between example and discussion.
9380 2003-02-24 Kevin Ryde <user42@zip.com.au>
9382 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
9383 format starting with "-".
9385 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9387 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
9388 is not portable inside Makefile.
9390 2003-02-20 Akim Demaille <akim@epita.fr>
9392 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9393 compiler says yeah, but preproc says nope, compiler is right.
9394 Conversely, prompt the reader to send a bug report to the
9395 maintainers of the package, not of Autoconf.
9397 2003-02-20 Klee Dienes <kdienes@apple.com>
9399 * bin/autoreconf.in (autoreconf_current_directory): Properly

9405 $ac_prefix_program.
9406 From Larry Jones.
9408 2002-12-23 Paul Eggert <eggert@twinsun.com>
9410 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9411 innocuous variant befor including <limits.h> or <assert.h>. This
9412 works around a bug reported by Albert Chin: HP-UX 11i
9413 (and earlier versions) have a <limits.h> that declares
9414 gettimeofday and many other functions.
9416 2002-12-03 Paul Eggert <eggert@twinsun.com>
9418 Version 2.57.
9420 * NEWS, configure.ac: Update version.
9422 * doc/fdl.texi: Upgrade to FDL version 1.2.
9424 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9425 nontrivially in main's body, so that f's external declaration is
9426 not optimized away in AIX. This should fix the bug reported by
9427 Martin Frydl in
9428 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9430 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9431 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9432 defined, to support freestanding compilers. This should fix the
9433 bug reported by Momchil Velkov in
9434 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9436 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9437 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
9438 obsolete AC_CHECK_TYPE. The missing empty arg was reported

9442 * Makefile.maint (www-gnu): New macro.
9443 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
9444 the location has moved.
9446 2002-12-02 Martin Frydl <martin@systinet.com>
9448 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9449 \(.*\) match is too long and there is something more to be checked.
9450 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
9452 2002-11-15 Akim Demaille <akim@epita.fr>

9458 * config/move-if-change: Indenting changes.
9459 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
9460 * configure.ac (AM_INIT_AUTOMAKE): here.
9461 Require 1.7.1.
9463 2002-11-14 Akim Demaille <akim@epita.fr>
9465 Version 2.55.
9467 * config/config.guess, config/config.sub, config/install-sh:
9468 Update from masters.
9470 2002-11-14 Akim Demaille <akim@epita.fr>
9472 * Makefile.maint: Sync with Bison, i.e.:
9473 (po-check): Scan .l and .y files instead of the
9474 .c and the .h files that they generate. This fixes the bug
9475 reported by Tim Van Holder in:
9476 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9477 Look for N_ as well as for _. Try to avoid matching #define for
9478 N_ and _.
9479 From Paul Eggert.
9481 2002-11-14 Akim Demaille <akim@epita.fr>
9483 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9484 From Paul Eggert and Albert Chin-A-Young.
9486 2002-11-14 Akim Demaille <akim@epita.fr>
9488 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9489 From Paul Eggert and Albert Chin-A-Young.
9491 2002-11-14 Kevin Ryde <user42@zip.com.au>
9493 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9494 than assigning in main, to avoid HP cc +O3 optimizing it away.
9496 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9498 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9499 option. Process --recheck after parsing all options. Pass -q
9500 option to configure on --recheck.
9501 (AC_OUTPUT): Pass -q from configure to config.status.
9502 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9503 arguments to record.
9504 * doc/autoconf.texi (config.status Invocation): Document
9505 config.status -q option.
9507 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9509 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
9510 Makefile.in if Makefile.am exists.
9511 (output): Strip `.am' from Makefiles. Don't
9512 output AC_CONFIG_FILES if no Makefiles were found.
9514 2002-11-07 Akim Demaille <akim@epita.fr>
9516 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
9517 (local_updates): New.
9518 * Makefile.maint: Update, from CVS Bison.
9519 (local_updates): New.
9521 2002-11-06 Akim Demaille <akim@epita.fr>
9523 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9524 declaration in extern "C" too.
9525 Reported by Roberto Bagnara.
9527 2002-11-06 Akim Demaille <akim@epita.fr>
9529 * tests/torture.at (Configuring subdirectories): Don't use grep
9530 -w.
9531 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9532 Reported by Ezra Peisach.
9534 2002-11-05 Akim Demaille <akim@epita.fr>
9536 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9537 Remove.
9538 We _have_ to stop using the old compatibility scheme that tried to
9539 avoid useless backslashes because Libtool 1.4.3 contains a
9540 AC_DEFINE([error_t], [int],
9541 [Define to a type to use for \`error_t' if it is not
9542 otherwise available.])
9543 We _have_ to quote the single quote and backslashes with \. The
9544 old compatibility scheme saw that ` was backslashed, and therefore
9545 did not quote the single quote. Hence before this patch, Autoconf
9546 was not compatible with Libtool.
9548 2002-11-04 Paul Eggert <eggert@twinsun.com>
9550 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

9555 2002-11-04 Akim Demaille <akim@epita.fr>
9557 Version 2.54c.
9559 * Makefile.maint (update, cvs-update, po-update, do-po-update):
9560 New.
9561 * config/texinfo.tex: Update.
9563 2002-11-03 Akim Demaille <akim@epita.fr>
9565 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9566 from...
9567 (&autoreconf): here.
9568 ($help, $make, &parse_args, &autoreconf_current_directory):
9569 Support -m/--make.
9570 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9572 2002-10-31 Bruno Haible <bruno@clisp.org>

9585 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
9586 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
9588 2002-10-31 Akim Demaille <akim@epita.fr>
9590 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
9591 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
9592 Make variable, not a shell variable.
9593 Suggested by Bruno Haible.
9595 2002-10-31 Akim Demaille <akim@epita.fr>
9597 * bin/autom4te.in (load_configuration): Reject #args out of any
9598 language.
9600 2002-10-31 Akim Demaille <akim@epita.fr>
9602 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
9603 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
9604 (_AC_RUN_IFELSE): Use it.
9605 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
9606 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
9607 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
9608 inline it.

9614 Suggested by Tim van Holder.
9616 2002-10-29 Paul Eggert <eggert@twinsun.com>
9618 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
9619 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
9620 Problem reported by Bruno Haible.
9622 2002-10-29 Akim Demaille <akim@epita.fr>
9624 * doc/autoconf.texi (Header Templates): Put also in words what the
9625 pictures says to assist free style readers.
9626 (Customizing autom4te): s/--cache=/--cache /.
9628 2002-10-29 Akim Demaille <akim@epita.fr>
9630 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
9631 sys/wait.h.
9632 sparc_address_test returns void.
9633 Use it with an argument, as prototyped.
9634 From Bruno Haible.
9636 2002-10-29 Akim Demaille <akim@epita.fr>
9638 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

9644 * tests/torture.at (Deep Package): New test.

9650 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
9651 * doc/autoconf.texi (Invoking autom4te): Rename as...

9878 2002-10-22 Akim Demaille <akim@epita.fr>
9880 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

9883 Quote for Perl '' strings, not "".
9884 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
9885 strings.
9887 2002-10-22 Akim Demaille <akim@epita.fr>
9889 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

9933 2002-10-16 Akim Demaille <akim@epita.fr>
9935 Because of caching, some files that no longer exist and are no
9936 longer required can still cause errors.
9937 Reported by Alexandre Duret-Lutz.
9939 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9940 to frozen files in @ARGV, as @ARGV must remain being a list of
9941 files. Rather, at M4 call sites, use this...
9942 (&files_to_options): New function.
9943 (&freeze): Use &error.
9944 (&up_to_date): If a file that was included according to the cache
9945 is no longer there, then the output is out dated.
9946 (&main): Don't even check whether a file is up to date is anyway
9947 --force is given.
9948 * tests/tools.at (autom4te cache): New.
9950 2002-10-16 Akim Demaille <akim@epita.fr>

9953 * bin/autoupdate.in (&parse_args): Kill old options.
9954 * bin/autoreconf.in (&parse_args): Remove dead options.
9955 Factor some code.
9956 (&autoreconf): Report the directories we enter *and leave*, so
9957 that error messages can be easily located, and use GNU Make
9958 format, so that Emacs' compile mode understands us.
9959 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9960 if some file was changed instead of `print'.
9961 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
9962 (&parse_args): Remove the dead options.

9994 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
9995 file name to enable parallel executions.
9996 From Sam Varshavchik.
9998 2002-10-08 Akim Demaille <akim@epita.fr>
10000 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10001 aclocal invocation, as Gettext macros might not be visible to
10002 aclocal.
10003 Instead of blindly running autopoint, scan configure.ac (not the
10004 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10005 Reported by Paul D. Smith.
10007 2002-10-08 Paul Eggert <eggert@twinsun.com>
10009 Work around problems found when POSIXLY_CORRECT=1 is set.
10010 None of this seems to have anything to do with POSIX, really,
10011 but it's how Perl getopt works.
10012 * bin/autom4te.in (parse_args): Configure GetOpt with
10013 "permute", too.
10014 * doc/autoconf.texi (Invoking autom4te):

10035 2002-09-28 Akim Demaille <akim@epita.fr>
10037 * tests/torture.at (Configuring subdirectories): Be robust to
10038 users who use config.site to require for a cache: in this case,
10039 the two last configure runs, using two different sets of
10040 arguments, trigger a legitimate error.
10042 2002-09-28 Akim Demaille <akim@epita.fr>
10044 * tests/m4sh.at (Functions Support, Functions and return Support):
10045 New.

10052 (autom4te): Specify that the sources are in the $srcdir.
10053 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10055 2002-09-28 Akim Demaille <akim@epita.fr>
10057 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
10058 (tm_zone): Move their rules to...
10059 * lib/autoconf/types.m4: here, using AN_ macros.
10060 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
10061 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
10062 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
10063 * lib/autoconf/programs.m4: here.

10071 * lib/autoconf/autoconf.m4: Include it.
10072 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
10073 that were listed in the original autoscan.list.
10074 * lib/autoconf/headers.m4: Similarly with headers.
10075 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10076 (.m4.m4f): Don't pass --prepend-include, since that's done by
10077 tests/autom4te itself.
10078 * lib/autoscan/Makefile.am: Include freeze.mk.
10079 (autoscan.list): New target --this file is no longer a source.
10080 (autoscan.pre): New file.
10082 2002-09-28 Akim Demaille <akim@epita.fr>
10084 * bin/autoscan.in (@kinds): Make them singular.
10085 Adjust all uses.
10086 (&init_tables): When --debug, report the list of rules to ease
10087 tracking changes in autoscan.list.
10088 * lib/autoscan/autoscan.list (function): Strip comments, sort.
10090 2002-09-28 Akim Demaille <akim@epita.fr>

10096 * bin/autoscan.in (&init_tables): Adjust.
10098 2002-09-28 Akim Demaille <akim@epita.fr>
10100 * lib/autoscan/functions, lib/autoscan/headers,
10101 * lib/autoscan/identifiers, lib/autoscan/makevars,
10102 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10103 `functions' line is now prefixed with `function:'.
10104 * bin/autoscan.in (&init_tables): Adjust.
10106 2002-09-28 Akim Demaille <akim@epita.fr>
10108 From now on, autoscan files must always map a macro name to a
10109 word: there is no `default' macro for autoscan.
10111 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10112 all.
10113 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10114 explicit.
10116 2002-09-28 Akim Demaille <akim@epita.fr>
10118 * bin/autoscan.in (%c_keywords): Remove.
10119 (&used): Keep only track of the words we might be interested in.

10121 checks.

10135 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
10136 the tmpdir must be created.
10137 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
10138 dir be in the build tree, instead of $TMPDIR.
10140 2002-09-27 Akim Demaille <akim@epita.fr>
10142 * bin/autoscan.in: Improve the comments.

10148 2002-09-26 Akim Demaille <akim@epita.fr>
10150 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
10151 Reported by Ralf Corsepius.
10152 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10154 2002-09-26 Akim Demaille <akim@epita.fr>

10159 (Limitations of Make): Some about `Single Suffix Rules and
10160 Separated Dependencies'.
10161 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10162 (ifnames, autoscan, autom4te): Un-factor into several rules.
10164 2002-09-25 Paul Eggert <eggert@twinsun.com>
10166 * BUGS (Interoperability bugs): New section. Mention libtool
10167 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10169 2002-09-24 Paul Eggert <eggert@twinsun.com>
10171 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10172 make handles suffix-rules differently from GNU make.
10174 * bin/Makefile.am (SUFFIXES, .in): Remove.
10175 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
10176 Move the body of the old .in rule here.
10178 2002-09-16 Akim Demaille <akim@epita.fr>
10180 i960 compilers create `b.out' files by default.
10181 Reported by Ralf Corsepius.
10183 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10184 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10186 2002-09-13 Paul Eggert <eggert@twinsun.com>
10188 * doc/autoconf.texi (Particular Headers): Remove obsolete
10189 reference to `struct timezone' in the description of
10190 AC_HEADER_TIME.
10192 2002-09-13 Akim Demaille <akim@epita.fr>
10194 Version 2.54.
10196 * config/config.sub, config/config.guess: Update.
10197 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10198 * Makefile.am: Adjust.
10200 2002-09-13 Akim Demaille <akim@epita.fr>
10202 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10203 reading config.log when the compiler is rejected.
10204 Suggested by Guido Draheim.
10206 2002-09-13 Akim Demaille <akim@epita.fr>
10208 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10209 (chdir_init) might hang when stat'ing mounted directories.
10210 Reported by Vance Shipley.
10212 2002-09-12 Akim Demaille <akim@epita.fr>
10214 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10215 the lists.
10217 2002-09-12 Akim Demaille <akim@epita.fr>
10219 * doc/autoconf.texi (Defining Symbols): Present two different
10220 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10221 difference between 1 argument calls, and 2-3 argument calls.
10223 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10225 * doc/autoconf.texi: Review grammar and punctuation.
10227 2002-09-11 Paul Eggert <eggert@twinsun.com>
10229 * doc/autoconf.texi: Fix minor formatting, spelling, and
10230 grammatical typos.
10231 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10232 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10233 is obsolescent.
10235 2002-09-11 Akim Demaille <akim@epita.fr>
10237 * doc/autoconf.texi (Questions): Rename as...
10238 (FAQ): this.
10239 (Defining Directories): New.
10241 2002-09-09 Akim Demaille <akim@epita.fr>
10243 * doc/autoconf.texi (Making testsuite Scripts): Update.
10244 Suggested by Nishio Futoshi.
10246 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10248 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10249 plain `@' is wanted.
10251 2002-09-09 Akim Demaille <akim@epita.fr>
10253 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10254 `duplicates', since the algorithm was too naive and could keep
10255 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10256 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10257 Reported by Ralf Corsepius.
10258 * tests/torture.at (Configuring subdirectories): Exercise these
10259 cases.
10261 2002-09-09 Akim Demaille <akim@epita.fr>
10263 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10264 looking for a replacement file.
10265 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10266 directory is relative.
10267 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10268 directory definition.
10269 Reported by Andreas Schwab and Jim Meyering.
10271 2002-09-06 Akim Demaille <akim@epita.fr>
10273 * doc/autoconf.texi (Setting Output Variables): Clarify what
10274 precious variables are.
10275 Suggested by Pontus Skoeld.
10277 2002-09-05 Akim Demaille <akim@epita.fr>
10279 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10280 (ifnames, autoscan, autom4te): Since we don't only depend on
10281 configure.ac variables (such as VERSION etc.), but also on prefix
10282 and so forth, depend on Makefile, not configure.ac.
10283 Reported by Alexandre Duret-Lutz.
10284 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10286 2002-09-05 Kevin Ryde <user42@zip.com.au>
10288 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10289 doesn't seem to be confined to ia64, just say "some versions".
10291 2002-09-04 Akim Demaille <akim@epita.fr>
10293 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10294 Automake 1.6c.
10295 * Makefile.am (maintainer-clean-local): Remove.
10296 (MAINTAINERCLEANFILES): Remove COPYING.
10298 2002-09-03 Paul Eggert <eggert@twinsun.com>
10300 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10301 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10302 Brinkmann.
10304 2002-09-03 Akim Demaille <akim@epita.fr>
10306 * configure.ac: Bump to 2.53d.
10307 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10308 as of today, on Automake's team suggestion.
10310 2002-09-03 Akim Demaille <akim@epita.fr>
10312 Version 2.53c.
10314 2002-09-02 Akim Demaille <akim@epita.fr>
10316 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10317 SITE_MACRO_DIR.
10318 * configure.ac: Disable SITE_MACRO_DIR.
10320 2002-09-02 Jim Meyering <meyering@lucent.com>
10322 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10323 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10324 Also, tweak grammar: s/make sure to/be sure to/.
10326 2002-09-02 Paul Eggert <eggert@twinsun.com>
10328 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10329 directory names are generally preferable to physical names.
10331 2002-09-02 Akim Demaille <akim@epita.fr>
10333 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10334 Reported by Raja R. Harinath.
10335 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10336 * bin/autoupdate.in: Use error instead of die.
10338 2002-09-01 Paul Eggert <eggert@twinsun.com>
10340 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10341 ordinary shell concatenation rather than echo+tr+sed command that
10342 runs afoul of a long-line-related sed bug in Solaris 8.
10344 * bin/autoheader.in (parse_args): --warning -> --warnings.
10346 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10347 stdout, as traditional "ls" does.
10348 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10349 _AC_COMPILER_EXEEXT_O): Likewise.
10350 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10352 * bin/autoconf.as: Add --prepend-include option. This patch was
10353 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10354 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10356 * bin/autoconf.in, configure: Regenerate.
10358 * doc/autoconf.texi (Special Shell Variables): Mention
10359 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10361 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10362 MAILPATH and set PS1, PS2, PS4 to default values, to work
10363 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10364 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10365 the Autoconf documentation specifies; fall back to "unset" only if
10366 this fails. Use a shell for-loop for this rather than an m4 loop,
10367 to shorten the output script.
10369 2002-08-30 Paul Eggert <eggert@twinsun.com>
10371 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10372 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10373 for the CDPATH problem. Document PWD.
10374 (Limitations of Builtins): Document the problem that "cd $foo" and
10375 "ls $foo" may refer to different directories in shells conforming
10376 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10377 example, since the old example is now out of date.
10379 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10380 FOO" and "ls FOO" talk about different directories; this catches
10381 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10382 spaghetti.
10384 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10385 of rolling our own unset.
10386 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10387 in practice we needn't worry about CDPATH if unset doesn't work.
10389 * Makefile.in, aclocal.m4, bin/Makefile.in,
10390 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10391 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10392 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10393 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10394 tests/Makefile.in: Regenerate with Automake 1.6.3.
10396 * config/config.guess, config/config.sub, config/mkinstalldirs:
10397 Update.
10399 * configure: Regenerate with self.
10401 2002-08-30 Kevin Ryde <user42@zip.com.au>
10403 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10404 default output.
10406 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10408 * bin/autom4te.in (Request::load): Correctly test for "do" read
10409 failure.
10411 2002-08-29 Akim Demaille <akim@epita.fr>
10413 * lib/Autom4te/General.pm (&xqx): New.
10414 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10415 hand, which is not portable.
10416 (&error): New.
10417 * bin/autom4te.in: Use them.
10418 Use &error instead of die.
10419 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10420 Adjust.
10422 2002-08-17 Paul Eggert <eggert@twinsun.com>
10424 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10425 default list of compilers to try, since it was long ago superseded
10426 by the ksh fc builtin. Suggested by Steven G. Johnson.
10428 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10430 * doc/autoconf.texi (Invoking autom4te): End the option table,
10431 fixing a bug introduced by the previous patch.
10432 (Limitations of Make): Add a 'target lookup' subentry in the
10433 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10435 2002-07-29 Mark D. Roth <roth@feep.net>
10437 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10438 options and use $AUTOM4TE_PATH.
10439 * doc/autoconf.texi: Remove documentation of autom4te
10440 --include-envvar and --site-macro-subdir options and document
10441 use of $AUTOM4TE_PATH.
10442 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10443 arguments from each language section.
10445 2002-07-29 Paul Eggert <eggert@twinsun.com>
10447 * doc/install.texi: Include copyright symbol in copyright notice.
10449 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10450 Replace with:
10451 (AM_MAKEINFOFLAGS): New macro.
10452 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10453 * Makefile.am (INSTALL): Use the new macros.
10454 Use -o rather than --output, since "missing" does not grok --output.
10456 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10458 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10459 comments do not always work. Never trust the exit status of
10460 `make -k'.
10462 2002-07-24 Kevin Ryde <user42@zip.com.au>
10464 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10465 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10467 2002-07-23 Paul Eggert <eggert@twinsun.com>
10469 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10470 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10471 apparently treats PATH="nonexistent" as if it contained ".".
10472 Bug reported by Stefan `Sec' Zehl.
10474 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10476 * doc/autoconf.texi (Limitations of Make): Mention the special
10477 handling of the obj/ directory by BSD make.
10479 2002-07-20 Kevin Ryde <user42@zip.com.au>
10481 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

10489 2002-07-19 Akim Demaille <akim@epita.fr>
10491 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
10493 2002-07-18 Akim Demaille <akim@epita.fr>
10495 Version 2.53b.
10497 2002-07-18 Akim Demaille <akim@epita.fr>
10499 * config/config.guess, config/config.sub: Update.

10503 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
10504 Automake's parts.
10506 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
10507 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
10508 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
10510 2002-07-18 Akim Demaille <akim@epita.fr>,

10523 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10524 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10525 latter was not run.
10527 2002-07-17 Akim Demaille <akim@epita.fr>
10529 * lib/Autom4te/General.pm (find_file): Browse the directories in
10530 the order they are given.
10532 2002-07-17 Akim Demaille <akim@epita.fr>

10550 macro directory, remove note that include path directories are

10552 * lib/autom4te.in: Use --prepend-include instead of --include.
10553 * tests/wrapsh.in: Use --prepend-include instead of --include.
10555 2002-07-17 Akim Demaille <akim@epita.fr>

10598 2002-06-27 Paul Eggert <eggert@twinsun.com>
10600 * config/install-sh: Quote $src. Prefer || to test's -o option,
10601 as per "Limitations of Builtins".
10602 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
10603 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
10605 * tests/mktests.sh: Use grep instead of fgrep, as per

10611 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
10612 so that we consistently test the just-built programs.
10613 * tests/wrappl.as: Likewise.
10615 2002-06-12 Paul Eggert <eggert@twinsun.com>
10617 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

10631 * doc/autoconf.texi: Add more dir entries.
10633 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10635 * bin/autom4te.in ($cache): Don't define using `$me', the name
10636 of the cache should not depend on the name under which autom4te
10637 was installed.
10639 2002-06-07 Akim Demaille <akim@epita.fr>

10656 AC_FUNC_FNMATCH_GNU.
10658 2002-06-07 Akim Demaille <akim@epita.fr>
10660 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
10661 Rosetta Stone for Unix.
10663 2002-06-07 Akim Demaille <akim@epita.fr>
10665 * bin/autom4te.in (warn_forbidden): When rejecting a token,
10666 suggest m4_pattern_allow.
10667 Suggested by Adam J. Richter.
10669 2002-06-07 Akim Demaille <akim@epita.fr>
10671 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
10672 ac_config_libobj_dir.
10673 (AC_CONFIG_LIBOBJ_DIR): New.
10674 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
10675 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.

10681 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
10682 * tests/mktests.sh (ac_exclude_list): Don't check
10683 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
10685 2002-06-06 Paul Eggert <eggert@twinsun.com>

10732 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10733 from the default list of compilers to try. Suggested by
10734 Kate Hedstrom.
10735 * NEWS: Document the above.
10736 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10738 2002-05-17 Paul Eggert <eggert@twinsun.com>
10740 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10741 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10742 This improves on an earlier suggestion by H. Peter Anvin.
10744 2002-05-16 Paul Eggert <eggert@twinsun.com>
10746 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10747 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10748 Both macros now accept an optional source-dir arg.
10749 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10751 * NEWS: Document this.
10752 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10754 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10755 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10756 not for GNU extensions; this undoes part of the 2000-11-03 change,
10757 reverting to 2.13-compatible behavior.
10758 Add new optional argument DIR.
10759 (AC_FUNC_FNMATCH_GNU): New macro.
10761 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10763 2002-05-08 Paul Eggert <eggert@twinsun.com>
10765 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10766 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10767 and it causes a 'test' syntax error if it fails.
10768 Bug reported by Stephen Gildea.
10770 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10771 If prototypes are supported, use them to check this at compile-time,
10772 instead of trying to check it at run-time. If we must do a run-time
10773 check, assume that setvbuf is standard when cross-compiling, as
10774 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10775 Bug reported by Paul D. Smith.
10777 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10778 argument specifying location of getloadavg.c. This removes a
10779 FIXME. This idea was taken from Jim Meyering's implementation in
10780 textutils.
10781 * doc/autoconf.texi (Particular Functions): Document this.
10782 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10783 that's what the code does; this fixes a bug reported by
10784 Paul D. Smith.
10786 2002-05-03 Akim Demaille <akim@epita.fr>
10788 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10789 autopoint instead of gettextize.
10790 ($uses_alocal): Rename as...
10791 ($uses_aclocal): this.
10792 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10793 Suggested by Bruno Haible.
10795 2002-05-03 Akim Demaille <akim@epita.fr>
10797 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10799 2002-04-29 Paul Eggert <eggert@twinsun.com>
10801 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10802 files to be 1 second older; just set them to be the same time.
10803 Also, sleep 1 second after the first aclocal, to work around
10804 problems with sub-second time stamps on the input files.
10806 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10808 * doc/autoconf.texi: Mention "set -e -x" lossage
10809 under node "Limitations of Builtins".
10811 2002-04-29 Akim Demaille <akim@epita.fr>
10813 * doc/install.texi: Better wording for setting variables when
10814 running configure.
10815 From Christian Cornelssen.
10817 2002-04-29 Akim Demaille <akim@epita.fr>
10819 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10820 of lack of $LINENO support, then the test will compare the $LINENO
10821 in testsuite vs. the lineno in the test file. This is wrong, of
10822 course.
10823 Be sure to protect it.
10824 Reported by Patrick Welche.
10826 2002-04-25 Akim Demaille <akim@epita.fr>
10828 * doc/autoconf.texi (Obsolete Macros): Typo.
10829 Reported by Vladimir Volovich.
10831 2002-04-25 Akim Demaille <akim@epita.fr>
10833 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10834 than some of the input files, hence, on the second run of aclocal,
10835 if some of its input are younger, make them older.
10836 Suggested by Paul Eggert.
10838 2002-04-25 Akim Demaille <akim@epita.fr>
10840 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10841 Thanks to Paul Eggert.
10843 2002-04-25 Akim Demaille <akim@epita.fr>
10845 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10846 and ac_subst_vars be sh variables containing the list of
10847 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10848 DEFAULT diversion.
10849 (_AC_INIT_PREPARE): Use them to log them.
10850 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10851 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10852 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10853 _AC_SUBST_FILES and _AC_SUBST_VARS.
10854 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10856 2002-04-24 Akim Demaille <akim@epita.fr>
10858 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10859 autoheader, so that automake does not complain about a missing
10860 config.h.in that was to be created.
10862 2002-04-23 Akim Demaille <akim@epita.fr>
10864 * bin/autoheader.in (parse_args): --warning takes an argument.
10865 Fixes PR/220.
10867 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10869 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
10870 and bb.out when cleaning up.

10888 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10889 Fixes false failures on Darwin.

10916 * doc/autoconf.texi: Follow the outline suggested in the GNU
10917 Sample Texts sections of the Texinfo 4.2 manual. Most
10918 importantly, this makes sure that the copyright notices appear in
10919 all output formats. You probably need Texinfo 4.2 to generate
10920 the manual now.
10922 Fix some bugs when using "$@" when there might be zero positional
10923 arguments in cases where this matters.

10971 Adjust Autoconf and Autotest.

10974 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10975 * lib/autotest/general.m4 (AT_INIT): Likewise.
10976 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

11023 (AC_CONFIG_LINKS): here.
11024 Adjust.
11025 Don't use the KILL diversion, as it kills spurious output, which
11026 results in failures being hidden.
11027 Use m4_defn where appropriate.
11028 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11029 after the second argument.
11030 Use m4_defn.
11031 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning

11072 2002-03-28 Kevin Ryde <user42@zip.com.au>
11074 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11075 to avoid versions of HP C which don't allow that.
11077 2002-03-27 Paul Eggert <eggert@twinsun.com>
11079 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
11080 (AS_SHELL_SANITIZE): Invoke it.
11081 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
11083 2002-03-26 Akim Demaille <akim@epita.fr>
11085 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
11087 2002-03-26 Akim Demaille <akim@epita.fr>
11089 * doc/autoconf.texi (Introduction): The GNATS base moved.
11091 2002-03-25 Paul Eggert <eggert@twinsun.com>
11093 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11094 as POSIX requires, as it doesn't work with Zsh.
11095 * doc/autoconf.texi (Assignments): Document the problem.
11097 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11099 * doc/autoconf.texi (Limitations of Make): Mention more issue
11100 about VPATH, overriding of macros in sub-makes, and handling of
11101 SHELL.
11103 2002-03-21 Paul Eggert <eggert@twinsun.com>
11105 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11106 problem with here-document buffer boundaries.
11108 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11109 when reinvoking the shell, to work around problems with installers
11110 who put strange things like "cd" commands in their environments.
11112 2002-03-19 Akim Demaille <akim@epita.fr>
11114 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
11115 From Aaron Ucko.
11117 2002-03-19 Akim Demaille <akim@epita.fr>
11119 * bin/autoscan.in (scan_file): Specify the location in `&used'
11120 invocations.
11121 From Nicolas Joly.
11123 2002-03-19 Akim Demaille <akim@epita.fr>
11125 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
11126 From Nishio Futoshi.
11128 2002-03-19 Akim Demaille <akim@epita.fr>
11130 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
11132 2002-03-18 Paul Eggert <eggert@twinsun.com>
11134 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11135 (Limitations of Usual Tools): Add mkdir section.
11137 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11138 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11139 back on AS_DIRNAME to compute prefixes otherwise; this is
11140 roughly what mkinstalldirs does. That way, we need not have
11141 our own filename disassembler. The old disassembler did not
11142 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11144 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11145 Create at_test_all by a series of assignments,
11146 not by a single assignment of a long string. The latter causes ksh
11147 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11148 presumably because of a buffer overrun.
11150 2002-03-14 Paul Eggert <eggert@twinsun.com>
11152 * lib/autotest/general.m4 (at_times_skip):
11153 Renamed from at_times. Now a boolean.
11154 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11155 says 'times: not found'.
11157 2002-03-14 Akim Demaille <akim@epita.fr>
11159 * bin/autoreconf.in (&study_gettextize): New.
11160 (&autoreconf): Handle newest gettextize.
11161 Rerun aclocal if needed.
11162 Suggested by Andreas Schwab.
11164 2002-03-13 Akim Demaille <akim@epita.fr>
11166 * doc/autoconf.texi (Special Shell Variables): More about IFS.
11168 2002-03-13 Akim Demaille <akim@epita.fr>
11170 * doc/autoconf.texi (Header Portability): New.
11171 Add information about stdint.h and inttypes.h from Paul Eggert.
11173 2002-03-13 Akim Demaille <akim@epita.fr>
11175 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
11176 -p'.
11177 From Bob Proulx.
11179 2002-03-12 Akim Demaille <akim@epita.fr>
11181 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
11182 m4_require.
11184 2002-03-11 Andreas Schwab <schwab@suse.de>
11186 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11187 does not do it if --with-lispdir is given.
11189 2002-03-08 Akim Demaille <akim@epita.fr>
11191 Version 2.53.
11193 2002-03-08 Akim Demaille <akim@epita.fr>
11195 * doc/autoconf.texi (Subdirectories): Clarify that the
11196 subdirectory should exist.
11198 2002-03-08 Akim Demaille <akim@epita.fr>
11200 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11202 2002-03-08 Akim Demaille <akim@epita.fr>
11204 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11205 aliases the actual variables, and modifications of the former
11206 affect the latter.
11208 2002-03-08 Akim Demaille <akim@epita.fr>
11210 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11211 because of C-c: have m4 output in tmp files, then mv them.
11213 2002-03-08 Akim Demaille <akim@epita.fr>
11215 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
11216 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
11217 * bin/ifnames.in: Copyright update.
11219 2002-03-08 Akim Demaille <akim@epita.fr>
11221 * doc/autoconf.texi (Invoking autom4te): New.
11223 2002-03-05 Akim Demaille <akim@epita.fr>
11225 * doc/autoconf.texi (Specifying Names): Clarification suggested by
11226 Kevin Ryde.
11228 2002-03-05 Akim Demaille <akim@epita.fr>
11230 Version 2.52i.
11232 2002-03-04 Akim Demaille <akim@epita.fr>
11234 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11235 * lib/autoconf/general.m4 (AC_INIT): More informative error
11236 message for LIBOBJ.
11238 2002-03-04 Akim Demaille <akim@epita.fr>
11240 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11241 parallel builds.
11243 2002-03-04 Akim Demaille <akim@epita.fr>
11245 * doc/autoconf.texi (Transforming Names): Equality between target
11246 and host is irrelevant.
11247 (Specifying Names, Canonicalizing): Remove all references to the
11248 backward compatibility hooks. Rather, collect them all into...
11249 (Hosts and Cross-Compilation): this new section.
11250 * doc/install.texi (System Type): Ditto.
11251 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11252 that `--host' implies cross-compilation.
11254 2002-03-04 Akim Demaille <akim@epita.fr>
11256 * doc/autoconf.texi (Evaluation Macros): New.
11257 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11258 useless.
11259 (_m4_foreach): Define the variant with immediate evaluation so
11260 that it contains exactly the items, not an expression which
11261 evaluation is the current item.
11262 (m4_re_string, m4_re_word): Don't over quote them.
11264 2002-03-04 Akim Demaille <akim@epita.fr>
11266 Instead of having stacking `shift's evaluated at the end, let
11267 `foreach' loops immediately evaluate them.
11269 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11270 $*. This is the n-th time I change my mind, but hopefully this is
11271 the last...
11272 (m4_lquote): New.
11273 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11274 efficient.
11275 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11276 it was only a hack for m4_text_wrap.
11277 (m4_car2): Remove, replaced by...
11278 (m4_cdr): New.
11279 (_m4_foreach): Adjust.
11280 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11281 m4_bpatsubst for clarification.
11283 2002-03-04 Akim Demaille <akim@epita.fr>
11285 * doc/autoconf.texi (Changequote is Evil): New.
11287 2002-03-03 Kevin Ryde <user42@zip.com.au>
11289 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
11290 on old systems like SunOS.
11292 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
11294 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

11298 of messages.
11300 2002-02-28 Akim Demaille <akim@epita.fr>
11302 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
11303 message to be sent.

11312 From Akinori Musha.
11314 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
11316 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
11317 translate \r\n to \n.
11319 2002-02-07 Akim Demaille <akim@epita.fr>
11321 Version 2.52h.
11323 2002-02-07 Akim Demaille <akim@epita.fr>
11325 Fix Autoconf PR/209.
11326 Also reported by Frank Denis.
11328 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
11330 2002-02-07 Akim Demaille <akim@epita.fr>
11332 Fix Autoconf PR/207:
11333 AC_PREFIX_PROGRAM fails with dashed program names
11335 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11336 variable when looking for the prefix program.
11337 Now it also works for shell variables.
11339 2002-02-07 Akim Demaille <akim@epita.fr>
11341 * doc/autoconf.texi (Limitations of Builtins): More about
11342 case/esac.
11344 2002-02-06 Akim Demaille <akim@epita.fr>
11346 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
11347 case/esac, some shells don't support it.
11348 Reported by Zack Weinberg.
11349 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
11351 2002-02-06 Akim Demaille <akim@epita.fr>
11353 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
11354 sure not to introduce newlines in at_groups.
11355 * lib/autotest/Makefile.am (autotest.m4f): Typo.
11357 2002-02-06 Akim Demaille <akim@epita.fr>
11359 * tests/torture.at (Configuring subdirectories): Skip if aclocal
11360 is not available.
11362 2002-02-05 Paul Eggert <eggert@twinsun.com>
11364 * doc/autoconf.texi (Specific Compiler Characteristics):
11365 Describe HP-UX cc bug workaround more accurately.
11366 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
11367 not unsigned long.
11368 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
11369 cross-compilers, too. This undoes some of the most recent change
11370 to this file.
11372 2002-02-05 Akim Demaille <akim@epita.fr>
11374 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
11375 to make sure they are up to date when `check' is run.
11377 2002-02-05 Akim Demaille <akim@epita.fr>
11379 * doc/autoconf.texi (Making testsuite Scripts): Document
11380 package.m4.
11382 2002-02-05 Akim Demaille <akim@epita.fr>
11384 * lib/freeze.mk: New.
11386 2002-02-05 Akim Demaille <akim@epita.fr>
11388 Implement `autom4te --freeze'.
11390 * bin/autom4te.in (&freeze): New.
11391 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
11392 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
11394 2002-02-05 Akim Demaille <akim@epita.fr>
11396 * bin/autom4te.in (&parse_args): Implement `frozen files are
11397 optional are the sum of the previous files on the command line'.
11398 Also, pass `--reload-state=' on them, so...
11399 (handle_m4): don't.
11400 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11401 (M4sh): Rely on M4sugar.
11402 (Autotest, M4sh, M4sugar): Use frozen files.
11404 2002-01-31 Akim Demaille <akim@epita.fr>
11406 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
11407 * doc/autoconf.texi (Initializing configure): Adjust.
11409 2002-01-30 Akim Demaille <akim@epita.fr>
11411 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
11412 alphanumeric to `-' instead of `_'.
11414 2002-01-30 Akim Demaille <akim@epita.fr>
11416 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
11417 for plain code, the other for cross-compilation code. The latter
11418 is now run with GCC only.
11419 * doc/autoconf.texi (Compilers and Preprocessors): New.
11421 2002-01-30 Akim Demaille <akim@epita.fr>
11423 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
11424 values.
11425 * doc/autoconf.texi (Initializing configure): Explain how to
11426 change AC_INIT default values.
11428 2002-01-29 Akim Demaille <akim@epita.fr>
11430 * tests/torture.at (Configuring subdirectories): Use configure.in,
11431 so that aclocal 1.4 works.
11432 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11434 2002-01-28 Akim Demaille <akim@epita.fr>
11436 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11437 needs an argument.
11439 2002-01-28 Akim Demaille <akim@epita.fr>
11441 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11442 AUTOTEST_PATH *after* it was set.
11443 Don't put `.' in the PATH: the user should be precise and `./' if
11444 needed. In addition, given that the test suite does some `cd', if
11445 `.' is in the path, the `tested programs' sections will report
11446 programs found in the test suite's directory, while during the
11447 tests (performed in their own directory), these programs are no
11448 longer visible. In other words, the results is confusing and
11449 useless.
11450 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
11452 2002-01-24 Akim Demaille <akim@epita.fr>

11461 2002-01-24 Akim Demaille <akim@epita.fr>
11463 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
11464 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
11465 Bourne. Use /bin/sh.
11466 From Andreas Buening.
11468 2002-01-24 Akim Demaille <akim@epita.fr>
11470 * config/config.guess, config/config.sub, config/texinfo.tex:

11480 Automake.
11482 2002-01-24 Akim Demaille <akim@epita.fr>
11484 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
11485 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.

11488 2002-01-21 Akim Demaille <akim@epita.fr>
11490 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
11492 2002-01-21 Akim Demaille <akim@epita.fr>
11494 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
11495 message on invalid options.
11496 * bin/autom4te.in (parse_args): Don't use
11497 Autoconf::General::getopt with non valid options.
11499 2002-01-17 Jim Meyering <meyering@lucent.com>
11501 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
11502 $ac_cv_exeext so we don't use an old, invalid, cached value.
11504 2002-01-11 Akim Demaille <akim@epita.fr>
11506 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
11507 Meyering.

11509 limitation.
11510 (Particular Functions): Document AC_FUNC_STRNLEN.
11511 * lib/autoscan/functions: Adjust.
11513 2002-01-06 Akim Demaille <akim@epita.fr>
11515 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
11516 package.m4, since is really depends upon configure.ac, not
11517 configure.
11518 * doc/autoconf.texi (testsuite Scripts): Adjust.
11519 * tests/Makefile.am (package.m4): New.
11520 EXTRA_DIST it since its a source.
11522 2002-01-06 Akim Demaille <akim@epita.fr>
11524 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11525 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11526 and PACKAGE_BUGREPORT from here...
11527 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11528 arguments.
11529 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11530 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
11531 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
11532 * tests/tools.at (autoheader): Adjust.
11533 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
11535 2002-01-06 Akim Demaille <akim@epita.fr>

11548 sometimes needing writable input.
11550 2001-12-17 Jim Meyering <meyering@lucent.com>
11552 * doc/autoconf.texi (New Macros): Tweak wording.
11554 2001-12-14 Akim Demaille <akim@epita.fr>
11556 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11557 trailing files, don't apply `-rf' to files which might not be
11558 created by configure (core, core.*, and *.core), but just `rm -f'.
11559 Suggested by Jonathan Kamens.

11563 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11565 2001-12-14 Akim Demaille <akim@epita.fr>
11567 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11569 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11571 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11572 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11573 abs_srcdir, top_srcpath to abs_top_srcdir.
11574 (_AC_OUTPUT_FILES): Adjust.
11575 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
11576 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
11577 * tests/wrappl.in, tests/wrapsh.in: Adjust.
11579 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
11581 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
11582 C/Fortran linking on HP/UX, by extracting the Fortran library
11583 search path from the LPATH line in the $F77 -v output.
11585 2001-12-12 Kevin Ryde <user42@zip.com.au>
11587 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
11588 forbidden file descriptors table.
11590 2001-11-26 Akim Demaille <akim@epita.fr>
11592 * bin/autoscan.in (%c_keywords): Build it at top level.
11593 Map to 1 in order to simplify its uses.
11595 2001-11-26 Akim Demaille <akim@epita.fr>
11597 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
11598 Remove $filepath, useless.
11599 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11600 variables, they are really part of the tokens.
11601 Split the input line on spaces and then look for tokens.
11602 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11603 because of `lex$U.$(OBJEXT)'.
11604 (&scan_files): Use "@list" instead of join.
11605 * doc/Makefile.am (CLEANFILES): Add *.fns.
11607 2001-11-26 Akim Demaille <akim@epita.fr>
11609 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11610 Remove, replaced by...
11611 * tests/wrappl.in: Be common for all the Perl executables.
11612 In particular autoscan and autoheader want -I.
11613 * configure.ac: Adjust.
11614 * lib/autoscan/headers: errno.h is portable.
11616 2001-11-26 Akim Demaille <akim@epita.fr>
11618 * bin/autoscan.in (used): New.
11619 Use it.
11621 2001-11-26 Akim Demaille <akim@epita.fr>
11623 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
11624 directives.
11625 (&scan_sh_file): Remove a duplicate pattern.
11626 (&check_configure_ac): Use long options.
11627 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
11629 2001-11-26 Akim Demaille <akim@epita.fr>
11631 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
11632 Before, having a line containing the opening of a multi line
11633 comment made the whole line be ignored.
11635 2001-11-26 Akim Demaille <akim@epita.fr>
11637 * doc/autoconf.texi (Using an Autotest Test Suite): New.
11638 (testsuite Scripts): Be one of its subsection.
11639 (Autotest Logs): New.
11641 2001-11-26 Akim Demaille <akim@epita.fr>
11643 Test groups are now run two directories deeper.
11645 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
11646 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
11647 at_top_builddir.
11648 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11649 top_srcdir, builddir and top_builddir.
11650 Use `at_*dir' relatively to the directory containing the
11651 suite, use `*dir' when relatively to the current group dir.
11653 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11655 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11656 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11657 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11658 spelling errors.
11660 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11662 * doc/autoconf.texi (Using System Type): Add an example of `case
11663 $host' usage so people quit using `case $target' everywhere.
11665 2001-11-22 Akim Demaille <akim@epita.fr>
11667 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11668 spotted by Jim Meyering.
11670 2001-11-16 Paul Eggert <eggert@twinsun.com>
11672 This patch implements a `long double' suggestion by Oliver Kiddle.
11674 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11675 static, to catch errors if the value isn't known at compile-time
11676 and the compiler supports dynamic arrays. Change its name from
11677 `_array_' to `test_array' to avoid potential name clashes.
11678 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11679 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11680 better than double. Catch a bug in GCC 2.95.2 x86.
11681 * doc/autoconf.texi (C Compiler): Document the above.
11682 * NEWS: Likewise.
11684 2001-11-13 Akim Demaille <akim@epita.fr>
11686 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11687 hand.
11688 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11690 2001-11-13 Akim Demaille <akim@epita.fr>
11692 * lib/autotest/general.m4 (AT_INIT): After having run the test
11693 group, go back to the initial directory, not to at_suite_dir.
11695 2001-11-13 Akim Demaille <akim@epita.fr>
11697 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11698 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11699 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11700 option.
11701 (AT_CHECK_CONFIGURE): Use absolute paths.
11702 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11703 The problem is still the old one: there is no means in M4 (that I
11704 know about) to create a defining macro, because there is no means
11705 to create `$1' etc., therefore, the defining macro ``swallows''
11706 all the arguments meant to the defined macro.
11708 2001-11-13 Akim Demaille <akim@epita.fr>
11710 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11711 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11712 configure.ac.
11713 * tests/aclocal.m4: Remove, as it is no longer used.
11715 2001-11-13 Akim Demaille <akim@epita.fr>
11717 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11718 variable names when referring to a single test group, or to
11719 `suite' when referring to the whole test suite.
11720 `at_last_test' is removed: m4 compute at_format itself.
11721 (at_stdout, at_stder1, at_stderr): New variables.
11722 (AT_CHECK): Use them.
11724 2001-11-13 Akim Demaille <akim@epita.fr>
11726 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11727 in PATH.
11728 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11729 Do it as soon as a test fails, don't wait till the end of the test
11730 suite.
11731 Don't remove $as_me.[0-9]*, since these files no longer exist.
11733 2001-11-13 Akim Demaille <akim@epita.fr>
11735 * tests/tools.at: Use absolute paths, since we are no longer run
11736 in place.
11738 2001-11-13 Akim Demaille <akim@epita.fr>
11740 Now that tests are running in their own private dir, there is no
11741 need to list the files to remove at the end of tests groups.
11743 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11744 (AT_data_files, at_data_files): Remove.
11745 (AT_CLEANUP, AT_DATA): Simplify.
11746 (AT_INIT): Adjust.
11747 Remove the group dir if !debug && !failed.
11748 * tests/atspecific.m4: Adjust.
11750 2001-11-13 Akim Demaille <akim@epita.fr>
11752 Start a new layout for Autotest: `testsuite' creates
11753 `testsuite.dir' in which the at-check-line etc. files are to be
11754 found, and `testsuite.dir/003' where the test group 3 is run.
11756 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11757 at_check_line_file, at_format, at_test_normalized, at_group_dir
11758 are new variables.
11759 Create the directories.
11760 Use absolute paths for at- files.
11761 (AT_CHECK): Adjust.
11763 2001-11-11 Michael Matz <matz@kde.org>
11765 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11766 (m4_car2): New.
11767 (m4_car): Properly quote arguments.
11769 2001-11-13 Akim Demaille <akim@epita.fr>
11771 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11772 with stricter rules on LIBOBJS.
11774 2001-11-12 Paul Eggert <eggert@twinsun.com>
11776 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11777 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11778 __PROTOTYPES too.
11780 2001-11-12 Akim Demaille <akim@epita.fr>
11782 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11784 2001-11-12 Akim Demaille <akim@epita.fr>
11786 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11787 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11788 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11789 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11790 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11791 specify to what the macro should be defined (typically to 1).
11793 2001-11-12 Akim Demaille <akim@epita.fr>
11795 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11796 From Jim Meyering.
11798 2001-11-12 Akim Demaille <akim@epita.fr>
11800 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11801 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11802 definition used by Automake where LEX is +/- "${missing} lex" and
11803 `missing' itself contains variables.
11805 2001-11-12 Akim Demaille <akim@epita.fr>
11807 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11808 Now that M4sh pushes BODY, the comments were output at the end of
11809 the test suites.
11811 2001-11-08 Akim Demaille <akim@epita.fr>
11813 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11814 that we can trace macros from aclocal.m4.
11815 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11816 obsoleted, and redirect to the former anyway.
11817 Reported by Ralf Corsepius.
11819 2001-11-08 Akim Demaille <akim@epita.fr>
11821 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11822 processed only if present.
11823 * tests/torture.at (Configuring subdirectories): Use autoreconf
11824 instead of successive calls to autoconf.
11825 Add a nonexistent subdirectory to exercise the patch above.
11826 Reported by Ralf Corsepius.
11828 2001-11-08 Kevin Ryde <user42@zip.com.au>
11830 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11831 doesn't accept .S files.
11833 2001-11-07 Akim Demaille <akim@epita.fr>
11835 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11836 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11837 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11838 * bin/autom4te.in (warn_forbidden): New.
11839 (handle_output): Use it.
11840 Read m4_pattern_forbid with messages.
11842 2001-11-05 Akim Demaille <akim@epita.fr>
11844 * bin/autom4te.in (--normalize): Remove.
11845 * lib/autom4te.in: Adjust.
11847 2001-11-05 Akim Demaille <akim@epita.fr>
11849 * tests/Makefile.am (testsuite): Rename this target as...
11850 ($(TESTSUITE)): this.
11851 From Nicolas Joly.
11853 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11855 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11856 the --prefix option, also remove it's argument.
11858 2001-11-05 Akim Demaille <akim@epita.fr>
11860 * doc/autoconf.texi (testsuite Invocation): Update.
11861 (Writing testsuite.at): Update.
11863 2001-11-03 Akim Demaille <akim@epita.fr>
11865 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11867 2001-11-03 Akim Demaille <akim@epita.fr>
11869 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11870 (&file_name_is_absolute): New, wrappers around routines from
11871 File::Spec.
11872 Use and export them.
11873 (&find_configure_ac): Optionally take a directory where to look at.
11874 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11875 the arguments.
11876 Default @ARGV to `.', not find_configure_ac.
11877 (&autoreconf): Argument is a directory.
11878 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11879 * doc/autoconf.texi (autoreconf Invocation): Update.
11881 2001-11-03 Akim Demaille <akim@epita.fr>
11883 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11884 (@export_forward_subs): New.
11885 Add basename, dirname, and fileparse.
11886 (@EXPORT): Adjust.
11887 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11888 Don't look for aclocal flags if we already know aclocal is not
11889 used.
11890 Move aclocal.m4t only if it exists.
11891 Reported by Ezra Peisach.
11893 2001-11-03 Akim Demaille <akim@epita.fr>
11895 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11896 passed on command line, defaulting to ./configure.ac if present.
11897 (&maybe_autoreconf, File::Find): Remove, unused.
11898 (&autoreconf): If autoconf is not used, don't try to trace.
11900 2001-11-02 Akim Demaille <akim@epita.fr>
11902 * configure.ac: Bump to 2.52g.
11904 2001-11-02 Akim Demaille <akim@epita.fr>
11906 Version 2.52f.
11908 2001-11-02 Akim Demaille <akim@epita.fr>
11910 * config/config.guess, config/config.sub, doc/standards.texi:
11911 * config/lispdir.m4: Update from masters.
11912 * configure.ac: Bump to 2.52f.
11914 2001-11-02 Akim Demaille <akim@epita.fr>
11916 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11917 Don't run aclocal when aclocal.m4 is not from aclocal.
11918 From Ezra Peisach.
11919 Don't run libtoolize and gettextize if --install is not given.
11921 2001-11-01 Paul Eggert <eggert@twinsun.com>
11923 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11924 be invoked before _AS_LINENO_PREPARE.
11925 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11926 than character ranges.
11928 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11929 invoking AS_BASENAME. Set the locale variables to 'C' if
11930 possible, as POSIX requires this to get the traditional
11931 behavior.
11932 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11934 2001-10-31 Paul Eggert <eggert@twinsun.com>
11936 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11937 with {}, as that triggers a bug in Bash 2.05.
11939 (_AS_LINENO_PREPARE): Use Sed rather than
11940 Awk. Fix the sed prepass to work even if there are multiple
11941 instances of $LINENO on the same line. Do not substitute for
11942 other variables like $LINENOT. Do not check file dates; such a
11943 check is unreliable on sufficiently fast machines, and removing
11944 the check makes the code simpler and more reliable. Check for
11945 output and chmod failures.
11947 * doc/autoconf.texi (Special Shell Variables): Document
11948 the above.
11950 2001-10-31 Akim Demaille <akim@epita.fr>
11952 * tests/Makefile.am (atconfig): Remove this target, Automake
11953 handles it now.
11955 2001-10-31 Akim Demaille <akim@epita.fr>
11957 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11958 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11959 provided, while it is optional.
11960 * configure.ac: Adjust.
11962 2001-10-26 Paul Eggert <eggert@twinsun.com>
11964 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11965 lib/Autom4te/Struct.pm:
11966 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11967 with 5.005_02.
11969 * doc/autoconf.texi (Special Shell Variables): Document some
11970 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11972 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11973 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11974 eval $LINENO is not portable in practice.
11976 2001-10-24 Akim Demaille <akim@epita.fr>
11978 * lib/Autom4te/General.pm (backname): New.
11980 2001-10-24 Akim Demaille <akim@epita.fr>
11982 * m4/: Remove, merged into...
11983 * config/: here.
11985 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11987 * doc/autoconf.texi (Shellology): Mention the problems with bash
11988 2.05's use of ANSI quoting in its `set' builtin.
11990 2001-10-22 Paul Eggert <eggert@twinsun.com>
11992 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11993 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11994 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11995 POSIX decided to standardize on the int flavor of strerror_r.
11996 Always do char* test, as there's no reason not to.
11997 Assign to a char* var, to catch strerror_r that returns int*.
11999 * doc/autoconf.texi (Particular Functions):
12000 Document the above changes. Also, document the fact that
12001 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
12003 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
12005 2001-10-20 Akim Demaille <akim@epita.fr>
12007 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
12008 the executable was missing from the log.
12010 2001-10-20 Akim Demaille <akim@epita.fr>
12012 * lib/Autom4te/General.pm (&update_file): If destination is
12013 unchanged, remove the source.
12014 (&up_to_date_p): Don't be verbose, be debug.
12015 * bin/autoreconf.in: No longer support --m4dir.
12016 (&autoreconf): Display the full path of the configure.ac we are
12017 studying.
12018 Trace it only once.
12019 Be sure to honor --force with gettextize.
12020 Always run aclocal.
12021 * doc/autoconf.texi: Adjust.
12023 2001-10-20 Akim Demaille <akim@epita.fr>
12025 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12026 Remove, dead.
12027 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12028 `intl' is already present, as it refuses unless --force.

12307 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

12478 * lib/autoconf/programs.m4: Use extensions listed in
12479 $ac_executable_extensions when looking for programs.
12481 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12483 * lib/autoconf/general.m4: Fix a small Englisho.
12484 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
12485 setting up ac_dir_suffix and ac_top_builddir.
12486 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
12488 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12490 * doc/autoconf.texi (File System Conventions): Clarify the use of
12491 PATH_SEPARATOR.
12492 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
12493 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
12494 be used instead of ':'.
12495 * lib/autotest/general.m4: Replace occurrences of ':' in
12496 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
12498 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12500 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
12501 arguments. Fixed a typo.
12503 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12505 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12506 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12508 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12510 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12511 * bin/autoupdate.in: Ditto.
12512 * bin/autoheader.in: Reworded a few comments.
12513 * bin/autoconf.in: Reworded help text for a few options.
12514 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12515 * bin/autoscan.in, bin/autoupdate.in: Ditto.
12517 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12519 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12520 already have $file). Set output files to binary mode (helps avoid
12521 CR issues on DOSish systems).
12523 2001-09-19 Akim Demaille <akim@epita.fr>
12525 * lib/autotest/general.m4: Englishoes.
12526 From Tim Van Holder and Alexey Mahotkin.
12528 2001-09-18 Paul Eggert <eggert@twinsun.com>
12530 * doc/autoconf.texi (Common Shell Constructs): New node,
12531 documenting AS_DIRNAME.
12532 (Limitations of Usual Tools): Refer to it when discussing dirname.
12533 Also, update discussion of POSIX standard to reflect latest draft.
12535 * lib/autoconf/c.m4:
12536 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12538 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12539 Do not pass a first argument with leading '-'
12540 to expr, by parenthesizing initial integers that might be negative.
12542 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12543 now merely checks whether it is an error to pass an argument
12544 to getpgrp.
12546 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12547 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12548 whether it is a (compile-time) error to pass an argument to
12549 getpgrp. This simpler test supports the revised documentation,
12550 and is all that AC_FUNC_GETPGRP's users really need.
12552 2001-09-18 Akim Demaille <akim@epita.fr>
12554 * doc/autoconf.texi (Limitations of Make) <$<>: New.
12556 2001-09-18 Akim Demaille <akim@epita.fr>
12558 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
12559 `{}'.
12560 * lib/autotest/general.m4 (AT_INIT): Adjust.
12562 2001-09-18 Paul Wagland <paul@wagland.net>
12564 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12565 correctly.
12566 Add test for AS_BASENAME.
12567 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12568 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12569 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12570 * tests/base.at: Fixed the expected responses. The old ones were
12571 one line out...
12572 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12573 the documentation claims it should (and how it behaved in 2.13).
12575 2001-09-18 Akim Demaille <akim@epita.fr>
12577 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12578 the AC_CONFIG_COMMANDS invocation.
12579 This also solves the name clash problems.
12580 Don't set the package's ID.
12581 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12582 No longer to be shipped.
12583 (version.in): Remove.
12584 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12585 * lib/autoconf/status.m4: Adjust.
12586 Use `m4_PACKAGE_STRING'.
12587 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12588 the only optional argument is the name of the test suite.
12589 Expect `package.m4' to define the package signature.
12590 * lib/autom4te.in (Autotest): Add `package.m4?'.
12591 * tests/Makefile.am (package.m4): New.
12592 * tests/suite.at: ifnames is a victim.
12594 2001-09-18 Akim Demaille <akim@epita.fr>
12596 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12597 AC_LIBSOURCE, AC_CONFIG_FILES.
12598 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12599 program version string doesn't match the package's.
12600 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12601 after `(cached)'.
12603 2001-09-17 Paul Eggert <eggert@twinsun.com>
12605 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12606 Allow expression to return any value that can fit into unsigned long
12607 (not int, as before). Check for output errors.
12609 2001-09-17 Bruno Haible <haible@ilog.fr>
12611 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12612 Always include <stdio.h> and <stdlib.h>. Evaluate
12613 the expression in an extra function before these includes. Call
12614 fprintf "%d" only after ensuring the argument is of type 'int'.
12615 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12617 2001-09-17 Paul Eggert <eggert@twinsun.com>
12619 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12620 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12621 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12622 when they don't exist.
12624 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12625 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12626 need it.
12628 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12629 version with the version used by fileutils 4.1, except use
12630 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12631 we don't need it.
12633 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12635 2001-09-13 Akim Demaille <akim@epita.fr>
12637 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12638 _first_.
12639 Reported by Gerrit P. Haase.
12641 2001-09-13 Akim Demaille <akim@epita.fr>
12643 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

12650 Use it.

12664 AT_tests_all for consistency.
12665 Set at_victims.
12666 (AT_VICTIMS): Similar to AT_KEYWORDS.
12667 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12669 2001-09-13 Akim Demaille <akim@epita.fr>
12671 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12673 2001-09-13 Akim Demaille <akim@epita.fr>
12675 * lib/autotest/general.m4 (AT_INIT): Create and remove
12676 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12677 test suites can cohabit.
12679 2001-09-13 Akim Demaille <akim@epita.fr>
12681 * tests/mktests.sh: Don't output banners for empty test files.
12683 2001-09-13 Akim Demaille <akim@epita.fr>
12685 Test suites can be run independently of configure.

12787 2001-09-05 Akim Demaille <akim@epita.fr>

12790 the maintainer is dumb enough to do that...
12792 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12793 excellence in M4 quotation: consider `__file__' is active.

12826 New, extracted from main.
12827 Use IO::File wherever possible.
12828 (input.m4): Be constant, use -I instead of hard coding $tmp.

12830 Don't invoke `_au_disable', since ac was not loaded, but just

12833 2001-08-31 Akim Demaille <akim@epita.fr>

12860 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12861 (testsuite Scripts): There is no such thing as `atconfig.in'.

12866 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

12881 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12882 debug scripts, in particular passing explicitly listed tests to
12883 run is stupid.
12885 2001-08-31 Akim Demaille <akim@epita.fr>
12887 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12888 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12889 Use directly autom4te, not autoconf.

12914 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12915 (autoheader): Pass --force since the test suite goes too fast for
12916 the time stamps.

12932 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12933 `autoheader: `config.hin' is created'.
12934 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12936 2001-08-31 Akim Demaille <akim@epita.fr>
12938 * bin/autoheader.in: Rewrite in Perl.
12939 * tests/autoheader: Adjust.
12941 2001-08-31 Akim Demaille <akim@epita.fr>
12943 * bin/autoconf.in (--include, -I): New option.
12944 Map --localdir, --autoconf-dir onto it.
12945 Forward autom4te's options instead of interpreting them.
12946 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12947 There is no such envvar since the inception of autom4te.cfg.
12948 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12949 * bin/autoupdate.in: Adjust, and perform more control.
12950 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12951 * tests/autoconf: Dittowise.
12953 2001-08-31 Akim Demaille <akim@epita.fr>
12955 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
12956 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12957 optionally `FILE'.
12958 Use -e, not -f, since /dev/null for instance is OK.
12959 (&parse_args): Adjust.
12960 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12962 2001-08-31 Akim Demaille <akim@epita.fr>
12964 * configure.ac: Also find tested executables in bin.
12965 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12966 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12967 installed peer executables, only PATH is allowed to resolve it.
12968 Pass `autoconf_dir' via options, not via invisible envvars.
12969 * lib/Autom4te/General.pm (&find_peer): Remove.
12970 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12971 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12972 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12973 find the executables for it.
12974 * tests/Makefile.am: Major cleanup. Too lazy to document...
12975 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12976 We only need PERL.
12977 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12978 indeed related to running the test suite, while passing
12979 --autoconf-dir and others is related to running non installed
12980 Autoconf executables. So don't do that, leave it to...
12981 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12982 * tests/autoscan: New.
12983 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12984 refer to library files: rely on --language.
12986 2001-08-29 Akim Demaille <akim@epita.fr>
12988 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
12989 s/--set/--language/.
12991 2001-08-29 Akim Demaille <akim@epita.fr>
12993 * doc/autoconf.texi: Strip the @nodes.
12994 Suggested by Paul Eggert.
12995 (Initializing configure): Typo.
12997 2001-08-29 Akim Demaille <akim@epita.fr>
12999 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
13000 Suggested by Paul Eggert.
13002 2001-08-29 Akim Demaille <akim@epita.fr>
13004 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
13005 download in a tmp dir.
13007 2001-08-29 Akim Demaille <akim@epita.fr>
13009 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
13010 case insensitive OSes out there :(

13013 2001-08-29 Akim Demaille <akim@epita.fr>
13015 * lib/autom4te.in: New.

13020 (&parse_args): Support --mode, --set, and --melt.
13021 * bin/autoconf.in: Simplify and adjust.
13022 * tests/Makefile.am (AUTOMAKE): Use --set.
13023 * tests/atlocal.in: Adjust.
13024 * BUGS: distcheck and check are weak.
13026 2001-08-29 Akim Demaille <akim@epita.fr>
13028 * lib/autotest/general.m4: Use
13029 foo=`(command) 2>/dev/null`
13030 not
13031 foo=`command` 2>/dev/null
13032 (at-devnull): Rename as...
13033 (AT-devnull): this.
13034 (--clean): Remove AT-* files too.
13035 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
13036 Reported by Nicolas Joly.

13040 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

13046 * doc/autoconf.texi (Function Portability): Mention C right shifts.
13048 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
13050 * lib/autotest/general.m4: Reword some messages.
13051 (AT_INIT): Check for the `times' builtin before using it.
13052 Support test ranges as arguments to the testsuite.
13053 Have -e imply -d as the help text suggested.
13055 2001-08-27 Akim Demaille <akim@epita.fr>
13057 * Makefile.maint: Formatting changes.
13058 (do-po-update, po-update, cvs-update, update): New targets.

13070 * lib/autotest/general.m4 (AT_INIT): Log the command line.
13071 Support `VAR=VAL' as arguments.

13073 may be set via the command line.
13075 2001-08-27 Akim Demaille <akim@epita.fr>
13077 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
13078 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
13079 first the build dirs, then the src dirs.

13082 2001-08-27 Akim Demaille <akim@epita.fr>
13084 * lib/autotest/general.m4 (AT_INIT): Output the definition of
13085 at_data_files earlier.
13086 (--clean, -c): New option.
13087 * tests/Makefile.am: Use this option.
13089 2001-08-27 Akim Demaille <akim@epita.fr>
13091 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
13092 `ac_top_builddir' to mimic Automake's vocabulary, which much more
13093 readable.
13094 Adjust callers.
13095 * doc/autoconf.texi (Configuration Actions): Document the vars
13096 available in commands.
13097 Emphasize the risks of collisions in init-cmds.

13102 (Initializing configure): this new node.
13104 2001-08-27 Akim Demaille <akim@epita.fr>

13128 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
13129 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
13130 -> ac_dir).
13131 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
13132 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

13160 (AMTAR): Help automake define it.

13162 needed, 1.5 can have a macro and a target with the same name.
13163 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
13164 * m4/strip.m4: New.

13177 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
13178 Adjust callers.
13179 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
13180 the name of the directory they're in, instead of the filename,
13181 since version.m4 is now in m4sugar, but m4_acversion must not be
13182 classified as an Autoconf macro.
13183 ($input_m4): Don't qualify the path to m4sugar.
13184 Rather, pass autoconf_dir to m4.
13185 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
13186 * tests/suite.at: Require 2.52c.
13188 2001-08-27 Akim Demaille <akim@epita.fr>

13200 of config.log on traps.

13202 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
13203 for config.status'.
13204 Open the log as soon as possible.
13205 Use the same log introduction as configure's.
13207 2001-08-22 Paul Eggert <eggert@twinsun.com>
13209 * doc/autoconf.texi (Indices): New node.
13210 Move indices out of the top level menu and into this submenu.
13212 2001-08-22 Akim Demaille <akim@epita.fr>
13214 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13215 AC_TRY_COMMAND.
13216 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.

13263 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
13264 program with AC_LANG_PROGRAM before feeding it to
13265 AC_COMPILE_IFELSE. Cleanup grep usage.
13267 2001-08-20 Akim Demaille <akim@epita.fr>
13269 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
13270 * NEWS, README, README-alpha, TODO, tests/README: This package is
13271 `Autoconf', not `autoconf' (the executable).
13273 2001-08-20 Akim Demaille <akim@epita.fr>
13275 Info readers seem to need `Index' in the index node title :(
13277 * doc/autoconf.texi: Reverse the 2001-08-15 change which
13278 simplified index node names.
13280 2001-08-20 Akim Demaille <akim@epita.fr>
13282 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
13283 arguments are not literals.
13284 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
13285 Specify the output variables, and macros defined.
13287 2001-08-20 Akim Demaille <akim@epita.fr>
13289 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
13290 (Examining Syntax) <AC_TRY_COMPILE>
13291 (Examining Libraries) <AC_TRY_LINK>
13292 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
13293 their arguments.
13294 Reported by Werner Lemberg.
13296 2001-08-20 Akim Demaille <akim@epita.fr>

13313 * lib/autoconf/general.m4 (_AC_OUTPUT_COMMANDS): Say what you do.

13315 test suite lives.
13316 Create `atconfig' automagically.

13322 2001-08-20 Akim Demaille <akim@epita.fr>
13324 Huh!?!?! There are still some user EOF tags used, which prevents
13325 their use in AC_CONFIG_COMMANDS for instance...
13327 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
13328 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
13329 `_CSEOF', or `_ATEOF', as appropriate.
13330 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,
13331 * lib/autotest/Makefile.am (check-local): Enforce this constraint.

13391 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

13409 * doc/autoconf.texi: Work around Texinfo buglets.
13410 (Transformation Rules): One example is enough, users are expected
13411 to have their brains on. And BTW, use DESTDIR.
13412 (dvar): New macro. Use it.

13464 (cvs-dist): depends upon it.
13466 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
13468 * tests/Makefile.am: Use a clean-local rule to remove
13469 autom4te.cache (it's a directory, not a file.
13470 * Makefile.am: Ditto (but maintainer-clean-local).
13472 2001-08-15 Akim Demaille <akim@epita.fr>
13474 * bin/autom4te.in (@m4_warning): New.
13475 (&handle_m4): Use it.
13476 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
13477 warnings are issued at each run.
13478 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
13479 is in the src tree.
13481 2001-08-15 Akim Demaille <akim@epita.fr>
13483 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
13484 don't waste time running `autoupdate --version' works.
13485 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
13487 2001-08-13 Akim Demaille <akim@epita.fr>
13489 * doc/autoconf.texi (ma): Rename this index as...

13546 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13548 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13549 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13550 * doc/autoconf.texi (C Compiler Characteristics): Update
13551 documentation for AC_C_BIGENDIAN.
13553 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13555 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13556 magic values from an object file when cross-compiling.
13557 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13559 2001-08-10 Akim Demaille <akim@epita.fr>
13561 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13562 effects.
13563 Suggested by Russ Allbery.
13565 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13567 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13568 current $prefix to the sub-configures.
13570 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13572 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13573 extension (needed on BeOS). Reported by Guido van Rossum.
13575 2001-08-09 Akim Demaille <akim@epita.fr>
13577 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13579 2001-08-07 Akim Demaille <akim@epita.fr>
13581 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13582 removed.
13583 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13584 No need to remove the files before and after the each test, before
13585 each test and at the end of the suite is enough.
13586 Display only the children `times', not the shell's.
13587 If the test failed or was skipped, at-times is not available.
13589 2001-08-07 Akim Demaille <akim@epita.fr>
13591 Always produce testsuite.log, including when there are no
13592 failures. This helps getting information on skipped tests, and
13593 duration of the tests. Err, implement the latter btw.
13595 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13596 Dump information on the first run of each test.
13597 (AT_CLEANUP): Create `at-times' containing the duration of the
13598 test group.
13600 2001-08-07 Akim Demaille <akim@epita.fr>
13602 The use of `dumpstat' revealed that `len' was used although it
13603 should not. m4_text_wrap was using it, but in the Autoconf world
13604 where it is legal. Hence (i) test M4sh in its own world, not
13605 Autoconf's, and (ii), ahem, fix the bug :)
13607 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13608 does not like `' instead of [].
13609 (AT_INIT): Forbid `^_?AT_'.
13610 And don't output such tokens.
13611 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13612 `script.as', and `autom4te.cache'.
13613 Remove `empty' and `macro' which are no longer used.
13614 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13615 * tests/m4sugar.at: Use it.
13616 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13618 2001-08-07 Akim Demaille <akim@epita.fr>
13620 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13622 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13624 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13626 2001-08-04 Akim Demaille <akim@epita.fr>
13628 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13629 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13630 AC_TRY_LINK.
13631 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13632 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13633 (AC_F77_MAIN): Likewise.
13635 2001-08-04 Akim Demaille <akim@epita.fr>
13637 Don't rely on M4sugar outputting the patterns in files, since we
13638 might process the output _without_ running m4, hence without these
13639 files.
13641 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13642 * bin/autom4te.in (@Request::includes): Remove, unused.
13643 (@Request::source): Rename as...
13644 (@Request::input): this.
13645 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13646 (&handle_output): Fetch the patterns from the traces.
13647 `$forbidden' and `$allowed' are constant: use m//o.
13648 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13649 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13651 2001-08-04 Akim Demaille <akim@epita.fr>
13653 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13654 autoconf', i.e., in addition to caching traces, cache the output.
13656 * bin/autom4te.in (Request::cache): Rename as...
13657 (Request::id): this.
13658 ($cache, $icache, $tcache, $ocache): New.
13659 (&handle_m4): Save M4 output in the cache instead of $tmp.
13660 (&handle_output): Adjust.
13661 (&up_to_date_p): Check that the output cache is up to date too.
13662 (top level): Run `&handle_m4' iff force or the cache is invalid.
13663 Run `&handle_output' if the output cache is more recent.
13665 2001-08-04 Akim Demaille <akim@epita.fr>
13667 * bin/autom4te.in ($force): New.
13668 (&parse_args, &print_usage): -f, --force is a new option.
13669 (&handle_output): CPP directives might have spaces after `#'.
13670 (&parse_args): The first file only can be frozen.
13672 2001-08-04 Akim Demaille <akim@epita.fr>
13674 Don't let autom4te compute the `include' traces several times:
13675 first check that the trace cache file is up to date, and then
13676 compare its timestamp with that of the output.
13678 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13679 the preamble. Don't require 5.005 as Autom4te::General does it,
13680 and better yet (use `use', not `require'!).
13681 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13682 Class::Struct as Autom4te::Struct.
13683 * lib/Autom4te/General.pm (File::stat): Use it.
13684 (&mtime): New, export it.
13685 * bin/autom4te.in: Use it.
13686 Declare `$req' is invalid if it is outdated.
13687 Don't declare it valid before saving it if something went wrong.
13689 2001-08-04 Akim Demaille <akim@epita.fr>
13691 Autom4te shall not encode Autoconf data, and preselecting traces
13692 must be proposed to the users.
13694 * bin/autom4te.in (@required_trace): Remove.
13695 (@preselect): New.
13696 (&parse_args, &print_usage): -p, --preselect is a new option.
13697 (&up_to_date_p): Adjust.
13698 * bin/autoconf.in: Preselect some Autoconf macros.
13700 2001-08-04 Akim Demaille <akim@epita.fr>
13702 * tests/tools.at (autoconf --trace: user macros): Check traces on
13703 macros invoked without arguments, and macros invoked with multiple
13704 lines arguments.
13706 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13708 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13709 arguments.
13711 2001-08-03 Akim Demaille <akim@epita.fr>
13713 * bin/autoconf.in ($@): Work around the usual sh bug.
13714 From Nicolas Joly.
13716 2001-08-03 Akim Demaille <akim@epita.fr>
13718 Clean up the handling of the M4 builtins tracing exception.
13720 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13721 trace requests.

13723 (@m4_builtin): this.
13724 (%m4_builtin_alternate_name): New.
13725 (&parse_args): Complete the trace requests with alternate names.
13726 (&handle_traces): Hence no longer do it here.
13727 (&trace_requests): Remove, unused.
13729 2001-08-03 Akim Demaille <akim@epita.fr>
13731 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13732 m4_if, and m4_wrap.
13734 2001-08-03 Akim Demaille <akim@epita.fr>
13736 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13737 (m4_divert_pop): Dump the whole diversion stack when a diversion
13738 mismatch happens.
13739 * bin/autom4te.in (&handle_output): Remember of the first
13740 occurrence of a possibly undefined macro, not the last.
13741 Complain about the possibly undefined macros in the same order as
13742 the appear in the output.
13743 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13744 * tests/tools.at (autoconf: forbidden tokens, basic)
13745 (autoconf: forbidden tokens, exceptions): No longer sort
13746 autoconf's stderr, as it is now deterministic.
13747 Check that `dnl' is caught.
13749 2001-08-01 Akim Demaille <akim@epita.fr>
13751 * configure.ac: Bump to 2.52c.

13766 `die'.
13767 (&END): New.
13768 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
13769 `END', as `Autom4te::General::END' will be triggered.
13770 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
13771 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

14163 compiler, not the preprocessor.
14164 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use

14166 the right thing.
14167 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
14168 earlier if there are.
14170 2001-07-03 Akim Demaille <akim@epita.fr>

14199 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
14200 dummy alternate main is required even if the user provides her own
14201 'main'.
14202 (AC_F77_MAIN): New macro to detect whether it is possible to
14203 provide an alternate 'main' function name, using the 'main' from
14204 the Fortran libraries.
14205 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
14206 cross-language link tests can be performed successfully.
14207 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
14208 after $LIBS, for consistency; this should be the general rule since
14209 the user may want to link to Fortran libraries that require $FLIBS.
14210 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
14212 2001-06-29 Pavel Roskin <proski@gnu.org>
14214 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
14215 at-stdout and at-stderr instead of removing the newline
14216 from the echo output, which is not guaranteed to work.
14218 2001-06-28 Jens Petersen <petersen@redhat.com>
14220 * aclang.m4 (_AC_PROG_CXX_EXIT_DECLARATION): Only add declaration to

14252 explicit macros is mapped to the default macro.
14253 (&print_unique): Remove, inlined in...
14254 (&output_kind): here.
14255 (File::Basename): Use it.

14263 characteristics in the logs.
14264 Suggested by Mo DeJong.
14266 2001-06-24 Akim Demaille <akim@epita.fr>

14277 2001-06-23 Akim Demaille <akim@epita.fr>
14279 * tests/torture.at (AC_ARG_VAR): Make it a single test instead of
14280 three as failures are unlikely, and speed matters.
14282 2001-06-23 Akim Demaille <akim@epita.fr>
14284 * doc/autoconf.texi (Redefined M4 Macros): New.
14286 2001-06-23 Akim Demaille <akim@epita.fr>
14288 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider
