1509 Fix regression in handling VAR=VALUE arguments to testsuite.
1510 * lib/autotest/general.m4 (AT_INIT) <PARSE_ARGS_END>: Detect

1514 regression in sourcing files.
1515 * tests/autotest.at (Using atlocal): New test to catch this.

1530 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1531 detection...

1533 argument.
1534 <DEFAULTS>: Delay computation of variables based on $at_dir...

1536 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1537 <PARSE_ARGS>: Parse new option.

1539 * tests/autotest.at (Choosing where testsuite is run): New test
1540 for this feature.
1541 (Keywords and ranges): Add test for missing -k argument.
1542 * NEWS: Document this.
1543 * doc/autoconf.texi (testsuite Invocation): Likewise.
1545 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1547 * build-aux/config.guess, build-aux/config.sub,
1548 build-aux/texinfo.tex: Sync from gnulib.
1549 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
1550 Likewise.
1552 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1554 * doc/autoconf.texi (Particular Programs): Do not mention the
1555 Autoconf version in which the AC_PROG_INSTALL change was done.
1556 Suggested by Paul Eggert.
1558 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1560 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1561 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1562 mode, we change to the source directory, also set $ac_pwd so we
1563 do not go back to the build tree for the next config subdir.
1564 * tests/torture.at (Deep Package): Extend test to contain two
1565 config subdirs on the top level.
1567 Fix parallel `maintainer-check'.
1568 * Makefile.am (maintainer-check-tests): Depend on `all'.

1598 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1599 check_SCRIPTS. Building the wrappers for `all' allows help2man
1600 to use them for the manpages.
1601 Report by Benoit Sigoure.
1603 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.

1616 Fix thinko in earlier patch - m4_join isn't defined yet.
1617 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1618 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1619 (m4_require): Use m4_do, not m4_join.
1621 Fix some whitespace tests on cygwin.
1622 * tests/tools.at (autom4te and whitespace in file names): Restore
1623 font-lock. Create $TMPDIR before it might be used.
1625 Fix spurious testsuite failure with M4 1.4.11.
1626 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1628 Optimize AC_REQUIRE.
1629 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1630 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1631 (m4_require): Avoid extra macro calls.
1633 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1635 * tests/torture.at (srcdir): Fix quoting.
1637 Do not pass top_srcdir to configure scripts in testsuite.
1638 * tests/autotest.at (srcdir propagation): Copy install-sh to
1639 source tree.
1640 (my only test): Drop setting of `top_srcdir'.
1641 * tests/base.at (Input/Output): Likewise.
1642 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1643 config.guess, and config.sub to test source tree.
1644 Drop AC_CONFIG_AUX_DIR setting.
1645 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1646 * tests/torture.at (Substitute a 2000-byte string): Drop
1647 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1648 (Substitute a newline, datarootdir workaround): Likewise.
1649 (Define a newline): Adjust for linenumber changes in configure.ac.
1650 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1652 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1653 if `pwd` contains whitespace.
1655 Quote $abs_top_srcdir in tests.
1656 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1657 * tests/tools.at (Syntax of the shell scripts): Likewise.
1659 * tests/m4sh.at (LINENO): Quote $0.
1661 Fix testsuite program wrapper for whitespace in `pwd`.
1662 The problem here is that the usual mantra is that command
1663 variables can contain arguments, thus we cannot just escape
1664 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1665 $top_builddir/tests directory early in $PATH, so that the
1666 wrappers are found by their plain name.
1667 * tests/wrapper.as: Put $testdir early in $PATH.
1668 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1670 Proper config.status --file/--header and $srcdir escaping.
1671 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1672 characters in $ac_file_inputs.
1673 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1674 accordingly.

1676 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1678 Fix Autotest for whitespace in `pwd`.
1679 * lib/autotest/general.m4 (AT_INIT)
1680 <at_func_create_debugging_script, Driver Loop>:
1681 Quote $at_group_dir.
1682 * tests/autotest.at (whitespace in absolute testdir): New test.
1684 * lib/autom4te.in: Quote @datadir@.
1686 Proper file name escaping in Autoconf programs and Perl modules.
1687 This includes escaping of characters special to the shell
1688 as well as special to Perl, e.g., leading `<' or `>'.
1689 For example, when $file starts with `>', `open ">$file"'
1690 wrongly tries to append to a different file.
1691 * bin/autoconf.as: Fix quoting for autom4te options.
1692 * lib/Autom4te/General.pm (shell_quote): New function, taken
1693 from coreutils, written by Jim Meyering.
1694 (mktmpdir): Use it.
1695 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1696 and open_quote.
1697 * bin/autoreconf.in (parse_args): Likewise.
1698 * bin/autoscan.in (main): Likewise.
1699 * bin/autoupdate.in (main): Likewise.
1700 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1701 * bin/ifnames.in: Likewise, XFile usage fixes.
1702 * tests/tools.at (autom4te and whitespace in file names): Extend
1703 test. Test twice, with special characters allowed on w32, and the
1704 rest. Test leading and trailing whitespace, for `open_quote'.
1705 (autotools and whitespace in file names): New, analogous test.
1706 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1707 by Russ Allbery and Eric Blake.
1709 Sync from Automake.
1710 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1711 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1712 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1713 (update_file, contents): Use it.
1715 * Makefile.am (autom4te-update): Rewrite for git.
1717 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1719 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1721 Fix copyright years.
1722 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1723 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1725 2007-12-04 Eric Blake <ebb9@byu.net>
1727 Manually resync with gnulib, since 'make cvs-update' no longer works.
1728 * build-aux/config.guess: New upstream version.
1729 * build-aux/config.sub: Likewise.
1731 When using older automake, don't downgrade build-aux/texinfo.tex.
1732 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1733 * doc/Makefile.am (TEXINFO_TEX): Add.
1735 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1737 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1738 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1739 #undef as this runs afoul of our new way of creating config.h.
1740 Problem reported by Jim Meyering in
1741 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1743 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1745 Fix autom4te for unusual characters in input file names.
1746 * bin/autom4te.in (files_to_options): Quote active characters
1747 for the shell.
1748 * tests/tools.at (autom4te and white space in file names):
1749 New test.
1751 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1752 Document that Tru64 awk always splits $0.
1754 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1756 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1757 `#AT_STOP_...' line at the end of each test.
1759 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1761 * lib/autotest/general.m4 (AT_INIT): For awk line number
1762 extraction script, ensure `$at_group' has a defined value
1763 even for the empty set, and properly quote its usage inside
1764 the awk script.
1766 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1768 * doc/autoconf.texi (Shell Functions): New chapter. Document
1769 IRIX sh $0 issue in functions, move content from ...
1770 (Portable Shell): ... here.
1771 (Shell Script Compiler): Note that shell functions are not
1772 totally unportable any more.
1774 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1775 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1777 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1778 extracting the line numbers of the last needed test.
1780 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1782 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1783 Fix quoting.
1785 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1787 Fix IRIX testsuite debugging failures: $0 in functions.
1788 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1789 Do not use $0 inside a function, as IRIX sh will set that to the
1790 function name rather than the script invocation name.
1792 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1793 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1795 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1796 to extract test scripts.
1797 (AT_INIT): Extract and cache test script line numbers.
1799 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1801 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1802 subsequent fixups; the awk -> here-document conversion trashes
1803 performance too much with AIX sh.
1805 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1807 * tests/local.at: Do not test m4, perl with AT_TESTED.
1809 Diagnose and guard against write errors dealing with config.status.
1810 The general idea is this: all write failures from `configure'
1811 writing `config.status' are indicated by $ac_write_error, which
1812 is only checked at the end. This is safe because config.status
1813 code is not executed before the file is complete. Other write
1814 failures, be they inside config.status, or in sub shell/awk
1815 scripts spawned from configure or config.status, typically need
1816 earlier checking, as their results are used right afterwards.
1817 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1818 before writing config.status, check afterwards.
1819 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1820 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1821 Set `ac_write_error' for write failures to config.status. Barf
1822 upon write failures to temporary files.
1823 Adjust note about closing and reopening the here-document.
1824 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1825 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1826 reopening the here-document.
1827 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1828 Ensure `ac_write_error' does not escape into config.status.
1829 Also, add a couple of code paths not yet exercised in the test
1830 suite: a config file with input from stdin, and a config header
1831 output to stdout.
1832 Suggestion for catching write errors by Bruno Haible.
1834 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1836 Avoid error with Tru64 awk and testsuite lines with many words.
1837 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1838 reads the testsuite, set the field separator to an unusual value,
1839 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1840 even splits the input if $i, i>0, was never accessed in the script.
1842 Revert 2007-10-17 change.
1843 * TODO: Multiline args in config files and headers mean something
1844 different and are not fixed, see
1845 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1846 Report by Stepan Kasal.

1850 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1852 AC_*_TOOL does not canonicalize the prefix
1853 * doc/autoconf.texi (Generic Programs): Do not say that
1854 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1856 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1858 Diagnose write errors in config.status instantiations.
1859 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

1861 on write errors.
1862 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1904 2007-11-13 Jim Meyering <meyering@redhat.com>
1906 Clean up the rule to create "expr".
1907 * tests/Makefile.am (expr): Don't redirect directly to target.

1925 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1926 configure.ac.

1955 are guaranteed to be built, remove the rules that tried to build
1956 them. Before, with a parallel build, these rules could lead to
1957 two processes writing tests/wrapper.in concurrently.
1959 Build in man/ only *after* building in bin/ and tests/.
1960 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1961 in both bin/ and tests/.
1963 Accommodate non-srcdir build-from-checkout.
1964 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1965 Use git's --git-dir=$srcdir/.git option.
1966 Add quotes, in case tarball_version_file contains shell meta-characters.
1967 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1968 * configure.ac: Pass "." to git-version-gen.
1970 Avoid spurious test failures due to version skew.
1971 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1973 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1975 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1976 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1977 Remove conftest.dSYM directory.
1978 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1979 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1980 Remove `conftest.*' recursively.
1981 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
1982 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1983 Likewise.
1984 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
1985 * THANKS: Update.
1986 Report and analysis by Jeff Squyres and Peter O'Gorman.
1988 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
1990 Fix typos in variable names.
1991 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
1993 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
1995 Document that $((expression)) is not portable.
1996 * doc/autoconf.texi (Shell Substitutions): Here.
1998 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2000 Ignore configure --help* errors due to LINENO-impaired shells.
2001 * tests/torture.at (Configuring subdirectories, Deep Package):
2002 In the --help* tests in read-only trees, make `.' temporarily
2003 writable again for the `stderr' file, and ignore errors due to
2004 the attempt to write configure.lineno.
2005 Report by Patrick Welche.
2007 2007-11-10 Jim Meyering <meyering@redhat.com>
2009 Generate package.m4 in build-dir, not srcdir.
2010 * tests/Makefile.am (package.m4): Adjust target.
2011 Don't redirect directly to $@.
2012 (CLEANFILES): Add package.m4.
2013 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2014 in $(srcdir).
2015 When running $(AUTOTEST), search "." before searching $(srcdir).
2017 Avoid a race condition that would make parallel "distclean" fail.
2018 * tests/Makefile.am (distclean-generic): Replace the default,
2019 automake-provided rule with an identical one, but with an additional
2020 dependency on distclean-local. Simply adding the dependency would
2021 cause automake not to emit the rule at all.
2022 * BUGS: Building with -jN works, now.
2024 Distribute git-version-gen.
2025 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2026 since GNUmakefile is distributed, and requires it for dist* rules.
2028 Remove two more generated files from version control.
2029 * INSTALL: Remove generated file.
2030 * lib/autoscan/autoscan.list: Remove generated file.
2032 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2034 * GNUmakefile (PATH): Remove stray apostrophes; they become
2035 part of PATH, which isn't wanted here.
2037 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2039 New config files output variable `top_build_prefix'.
2040 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2041 `top_build_prefix'.
2042 * doc/autoconf.texi (Preset Output Variables): Document it.
2043 * NEWS: Update.
2044 Report by Bob Friesenhahn.
2046 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2047 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2048 function, to parametrize arithmetic with expr vs. the shell.
2049 Use it where possible.
2050 Suggestion by Benoit Sigoure.
2052 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2054 Adjust the documentation of autotest WRT atlocal.
2055 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2056 when using Automake, to write a rule to produce atlocal, since it's
2057 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2058 distributed, not atconfig.in.
2060 2007-11-04 Eric Blake <ebb9@byu.net>
2062 Update list information.
2063 * README: Mention new autoconf-commit list.
2064 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.

2070 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2072 * build-aux/.gitignore: Ignore mkinstalldirs.
2074 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2076 2007-11-03 Jim Meyering <meyering@redhat.com>
2078 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2079 * build-aux/git-version-gen: This syncs from coreutils.
2081 Adjust the build procedure so "make check" works reliably.
2082 * README-hacking: Include an extra step between "make" and
2083 "make check" to ensure that the latter passes.
2085 Use just-built tools, when possible.
2086 * GNUmakefile (PATH): Set and export here, ...
2087 (dummy): ... rather than here.
2089 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2090 and Andreas Schwab <schwab@suse.de>
2092 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2093 exit status bug.
2095 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2097 * configure.ac (AC_PREREQ): Require version 2.60, for
2098 AC_PROG_SED, AC_PROG_GREP.
2100 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2101 and Jim Meyering <meyering@redhat.com>
2102 and Andreas Schwab <schwab@suse.de>
2103 and Eric Blake <ebb9@byu.net>
2105 Document a bug in GNU Bash with compound commands and redirections.
2106 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2107 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2108 workaround.
2110 2007-11-03 Eric Blake <ebb9@byu.net>
2112 Support m4 1.4.5 in testsuite.
2113 * tests/torture.at (Define a newline): Exclude line numbers in
2114 error message.
2115 Reported by Ralf Wildenhues.
2117 2007-11-03 Jim Meyering <meyering@redhat.com>
2119 Remove automake-provided files from version control.

2122 * build-aux/missing: Remove file.
2123 * build-aux/mdate-sh: Remove file.
2124 * build-aux/.gitignore: New file.
2125 Suggestion from Ralf Wildenhues.
2127 2007-11-03 Eric Blake <ebb9@byu.net>
2129 Adjust version comparison to account for git snapshot numbers.
2130 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2131 component separator.
2132 * doc/autoconf.texi (Number processing Macros)
2133 <m4_version_compare>: Document this change.
2134 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2136 2007-10-30 Bruno Haible <bruno@clisp.org>
2138 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2139 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2140 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2141 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2142 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2143 Suggested by Paul Eggert.
2145 2007-10-28 Jim Meyering <meyering@redhat.com>
2147 * README-hacking: Autoconf, Automake, and Perl are required to build.
2148 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2150 2007-10-28 Jim Meyering <meyering@redhat.com>
2152 README-hacking: Recommend running autoreconf -vi.
2153 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2154 so that we use just-built tools when they're available.
2155 Suggestions from Ralf Wildenhues.
2157 2007-10-28 Jim Meyering <meyering@redhat.com>
2159 Make inter-release --version output more useful.
2161 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2162 which indicates that it is built using the 19th change set
2163 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2164 is a prefix of the commit SHA1.
2165 * build-aux/git-version-gen: New file.
2166 * configure.ac: Run it to set the version.
2167 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2168 * Makefile.am (dist-hook): Arrange so that .version appears only
2169 in distribution tarballs, never in a checked-out repository.
2170 * .gitignore: Add .version here, too. Just in case.
2171 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2172 not configure.ac, now that the version number changes automatically.
2174 Ensure that $(VERSION) is up to date for dist-related targets.
2175 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2176 git-version-gen doesn't match $(VERSION), but only for dist targets.
2178 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2180 Fix `Deep Package' failure with a configure script early in PATH
2181 * tests/torture.at (Deep Package): Add `.' early in PATH.

2199 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
2200 documentation.
2202 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
2204 * doc/make-stds.texi: Update from gnulib.
2206 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2207 and Eric Blake <ebb9@byu.net>
2209 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
2210 problem reported by Bruno Haible in
2211 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2213 2007-10-22 Eric Blake <ebb9@byu.net>
2215 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2216 preprocessor.
2218 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2220 Don't check for bug in HP-UX 11.00 cpp.
2221 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2222 Use -1ull rather than -1u, since that causes problems with gnulib; see
2223 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
2225 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2227 * tests/autotest.at (Backquote command substitution)
2228 (Multiline backquote command substitution)
2229 (Parenthetical command substitution)
2230 (Multiline parenthetical command substitution): Fix typos in
2231 test names.
2233 2007-10-21 Eric Blake <ebb9@byu.net>
2235 * configure: Regenerate.

2241 escaping of backslash in here-documents.
2243 Fix `Deep Package' test failure on FreeBSD.
2244 * tests/torture.at (Deep Package): Do not add `.' to $PATH
2245 unnecessarily. Do not try running `/bin/sh configure' with a
2246 configure script to be found in $PATH, if the shell does not do
2247 this resolution. Fixes test failure on FreeBSD.
2249 Fix config header generation with AIX awk.
2250 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2251 script, use helper array D_is_set, as `" 0"' does not evaluate
2252 to true for AIX awk.
2254 2007-10-21 Eric Blake <ebb9@byu.net>
2256 * tests/autotest.at (Banners): Reinstate test, with typo

2289 * lib/autotest/general.m4 (BANNERS): New named diversion.
2290 (TESTS_END): Diversion no longer used.
2291 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
2292 shell function, which prints only as needed, using an associative
2293 array of banner text from a special diversion.
2294 <PARSE_ARGS_END>: No longer need awk to find banners.
2295 <TESTS>: Banners are no longer processed by main driver loop, so
2296 we no longer need case statement.
2297 (AT_BANNER): Rewrite to populate new diversion.
2298 (AT_SETUP): Each test invokes its own banner. No output is needed
2299 to the TESTS diversion.
2300 * doc/autoconf.texi (Writing Testsuites): Document slight
2301 semantics change.
2302 * tests/autotest.at (AT_BANNERS): Enhance test.

2323 (_m4_append_uniq): New helper macro.
2324 (m4_append_uniq_w): New macro.
2325 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Fix
2326 duplication bug by using new macro.

2328 programs with stdin redirected, so programs that don't
2329 understand --version won't try to behave interactively.
2330 * tests/autotest.at (Tested programs): Catch this bug.
2331 * tests/m4sugar.at (m4@&t@_append): Test new macro.

2345 --version. Format functions consistently, trying to fit in 80
2346 columns.
2347 (TEST_FUNCTIONS): Based on recent changes, rename...
2348 (TEST_GROUPS): ...to this.
2350 Reject FreeBSD m4.
2351 * m4/m4.m4 (AC_PROG_GNU_M4): Also check for frozen file support.

2365 Autotest: do not use shell functions for individual tests.
2366 * lib/autotest/general.m4 (AT_INIT) <at_func_test>: Merely
2367 extract the source test source, do not invoke it.

2390 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Avoid errors when `.'
2391 is not writable, use 'cp -p' in this case, in the hope that it
2392 will not actually be needed. Still try removing files, in case
2393 of other write errors.
2394 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
2395 use $as_myself, not $0.
2396 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
2397 exist, try again in the the source tree. This change assumes
2398 that the subpackage configure script is capable of running
2399 --help=recursive in the source tree.
2400 * tests/torture.at (Configuring subdirectories, Deep Package):
2401 Adjust tests to expose both issues, also try invocation as
2402 `sh configure ...' and plain `configure ...' with PATH adjusted.

3392 renamed to "autoconf-invocation"
3394 * doc/autoconf.texi (Caching Results): The CACHE-ID variable
3395 in the examples should not use the internal "ac_" prefix.

3409 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
3410 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
3411 section titles and other comments; no code change.
3413 2007-05-01 Kevin Ryde <user42@zip.com.au>
3415 * doc/autoconf.texi (Particular Programs): Typo
3416 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
3418 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
3420 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
3421 'configure' will fail if the shell lacks proper support for shell
3422 functions. Suggested by RMS.
3424 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
3426 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
3427 about Solaris /bin/printf '%010000x' 123. Problem reported by
3428 Bruno Haible.
3430 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
3432 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3433 for a.* when searching for executables, as this prevents users
3434 from having files like a.c. Problem reported by Ralf Wildenhues in:
3435 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3436 This fixes a problem introduced on 2000-12-19.

3440 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
3441 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
3442 via Bruno Haible.

3446 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3447 AC_CHECK_TYPE, AC_CHECK_TYPES.
3448 * doc/autoconf.texi (Generic types): C types must be type-names
3449 (the C terminology), not type-ids (the C++ term). C++ types
3450 must not be anonymous.
3451 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3452 for C++; this drops support for anonymous struct and union types,
3453 which were problematic anyway.
3454 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3455 for C++.
3457 2007-04-12 Jim Meyering <jim@meyering.net>

3469 * doc/autoconf.texi (Generic Types): Document the restrictions
3470 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3471 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3472 with objects too. Document the restrictions on its use.
3473 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3474 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3475 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3476 works but the latter doesn't, then it's a valid type.
3477 This lets people use function types and so forth.
3478 For C++ there doesn't seem to be a simple solution, so leave it alone.
3479 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3480 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3481 AC_CHECK_TYPE; that wasn't documented or necessary.
3483 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3485 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3501 obsolescent. Suggested by Bruno Haible.
3502 * NEWS: Document this.
3504 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
3506 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
3507 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
3508 default still has the problem. Problem reported by Bruce Korb.

3528 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3529 checks for unsigned long long int.
3531 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3533 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3534 nonstandard grep R.E. escape sequences.
3536 2007-03-17 Jim Meyering <jim@meyering.net>
3538 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3539 (Limitations of Usual Tools): Also list \< and \>, and mention that
3540 HP-UX's grep, like the one from Solaris, does not support that syntax.
3542 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3544 * doc/autoconf.texi (Specifying Names): `--host' does not
3545 change the build type.
3547 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3549 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3550 suggests AC_CONFIG_HEADERS.

3557 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
3558 Problem reported by Paolo Bonzini in:
3559 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
3560 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3561 universal binaries. Problem reported by Elias Pipping.
3563 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3565 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3566 * doc/autoconf.texi (C Compiler): Document this. There is a new
3567 extra argument ACTION-IF-UNIVERSAL.
3568 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3569 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3570 Reindent for sanity's sake.
3572 2007-02-24 Eric Blake <ebb9@byu.net>
3574 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3575 copyright.

3580 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3582 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3583 status of rm so we know when it failed.
3584 If cleaning of test dir failed before running the test, warn.
3585 Output the line separator in verbose mode before the warning
3586 to make clear the warning belongs to the following test.
3588 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

3603 carriage return.
3604 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3605 with traditional Awk and begin.
3606 * tests/torture.at (Limitations of Builtins): Document the problem

3613 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3614 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3615 will not wait for input with a script containing only a BEGIN
3616 rule.
3618 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>

3640 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3642 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3643 latest version.
3644 (Shell Substitutions): Note problems with @{var:=value} etc.
3645 Add a new section for problems with @{#var} etc. Problem noted
3646 by Ralf Wildenhues. See:

3649 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3651 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3652 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3653 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3654 substitution will still be done by the special code.
3655 Report by Jim Meyering.
3657 * doc/autoconf.texi (File System Conventions): Mention that
3658 $PATH_SEPARATOR is for the build system only.

3674 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3676 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3678 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3679 early on the reader side, drop stderr of the input to avoid
3680 `broken pipe' error output; this may happen even with shell
3681 builtin `echo' of some bash versions. Reports by Ian Macdonald
3682 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3684 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3686 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

3696 Fix some wording problems noted by Paolo Bonzini in:
3697 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3698 * doc/autoconf.texi (Signed Overflow Examples): Give more
3699 discussion about the allow_superuser_privileges example,
3700 and change it a bit to make things clearer.
3701 (Optimization and Wraparound): Clarify whether the compiler
3702 will generate an infinite loop for the example derived from
3703 Autoconf's mktime test.
3704 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3705 Also, clarify unsigned multiplication overflow.
3707 2007-01-04 Eric Blake <ebb9@byu.net>
3709 * bin/Makefile.am (RELEASE_YEAR): New macro.
3710 (edit): Use it to supply correct copyright year to scripts.
3711 * bin/autoconf.as (version): Use it.
3712 * bin/autoheader.in ($version): Likewise.
3713 * bin/autom4te.in ($version): Likewise.
3714 * bin/autoreconf.in ($version): Likewise.
3715 * bin/autoscan.in ($version): Likewise.
3716 * bin/autoupdate.in ($version): Likewise.
3717 * bin/ifnames.in ($version): Likewise.
3719 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3721 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3722 feedback. The most important changes document what happens when
3723 you convert an out-of-range value to a signed integer type, and
3724 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3725 a + b.
3727 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3728 rewrite, taking notions from the recent discussion on the gcc and
3729 autoconf mailing lists; please see
3730 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3731 and follow the many links.
3732 (Integer Overflow Basics, Signed Overflow Examples):
3733 (Optimization and Wraparound, Signed Overflow Advice):
3734 (Signed Integer Division): New sections.
3736 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3738 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3739 preprocessor macro arguments in traced name.
3740 * doc/autoconf.texi (Defining symbols): Document longstanding
3741 support for AC_DEFINE-ing macros with arguments, and document
3742 behavior when the same variable has multiple AC_DEFINEs.
3743 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3744 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3745 macros directly, giving much shorter and simpler code.
3747 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3749 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3750 space before "$ac_configure_args" to prevent a 'config.status
3751 --recheck' failure if ac_configure_args doesn't contain a leading
3752 space. This works around a problem with the XEmacs configure.ac,
3753 which uses the (undocumented) ac_configure_args variable
3754 inconsistently with Autoconf.
3756 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3758 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3759 Include <limits.h>, and use its INT_MAX to rewrite the
3760 j loop so that it does not overflow 'int'. Problem reported by
3761 Ralf Wildenhues in
3762 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3763 Play it safe by shifting left by 1 rather than multiplying by 2,
3764 as GCC is less likely to optimize this away when the value
3765 is signed (when it assumes overflow leads to undefined behavior).
3766 Also, don't assume time_t uses two's complement.
3768 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3770 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3771 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3772 dumps core on it. Report by Tim Rice.
3774 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3776 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3777 --disable-option-checking to --help output even when
3778 AC_PRESERVE_HELP_ORDER is not used.
3779 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3780 --with argument, rather than argument with [-.] replaced by
3781 underscores.
3782 * NEWS: Fix typo in previous change; the news was in the
3783 wrong section.
3785 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3787 * NEWS: Warnings are now generated by default for unknown
3788 --enable-* and --with-* options.
3789 * doc/autoconf.texi (Option Checking): Renamed from
3790 (Configure Option Checking). Tighten up the wording a bit.
3791 (External Software, Package Options): Cross-reference to Option
3792 Checking, and use this to shorten our section.
3793 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3794 "$x" to test "x$foo" != x.
3795 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3796 Don't warn if $enable_option_checking is "no".
3797 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3798 ac_unrecognized_opts to the empty string.
3799 Don't echo the unrecognized opts, as this might mishandle
3800 backslashes or leading -.
3801 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3802 usage next to the other --disable-FEATURE options in the
3803 help string.
3805 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3807 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3808 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3809 Print warning for unrecognized --with and --enable options
3810 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3811 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3812 Disable option checking when subdirs are configured.
3813 (AC_OUTPUT): If warnings are enabled, print warning about
3814 unrecognized --with and --enable options at the end of
3815 the configure output (as well as at the beginning).
3816 * doc/autoconf.texi (Option Checking): New node.
3817 Document new option warning functionality.
3819 2006-12-16 Eric Blake <ebb9@byu.net>
3821 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3822 * NEWS: Start news for current version.
3824 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3826 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3827 Define HAVE_GETMNTENT to 1, not to the empty string.
3828 Problem originally reported by Jochen Friedrich in
3829 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3831 This change prompted by a problem report by Andrey Simonenko in
3832 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3833 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3834 object-like macros only, in the traditional portable character
3835 set.
3836 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3837 Warn about attempts to define things that are not identifiers.
3838 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3839 awful hack that AC_DEFINEd macro names containing parentheses.
3841 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3843 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3844 too drastic, even if Texinfo in theory requires it for info mode.
3846 (config.status Invocation): Renamed back from Recreating a
3847 Configuration).
3848 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3849 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3851 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3853 * NEWS: Version 2.61a.
3855 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3856 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3858 * NEWS: Document changes with echo and printf, and the lack
3859 of limits on the total size of multi-line values of substituted
3860 variables, and the AC_FUNC_FSEEKO fix.
3862 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3864 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3865 Writing configure.ac.
3866 (Autoconf Input Layout): Renamed from configure.ac Layout.
3867 (Recreating a Configuration): Renamed from config.status Invocation.
3868 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3869 (acconfig Header): Renamed from acconfig.h.
3870 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3871 (Writing Testsuites): Renamed from Writing testsuite.at.
3872 (Autom4te Cache): Renamed from autom4te.cache.
3874 * BUGS: Remove mention of VPATH problem, since it's now documented
3875 not to be a bug in the Autoconf build procedure itself, but rather
3876 a problem with the proprietary `make' programs.
3878 * doc/autoconf.texi (Build Directories): Add a cross reference
3879 to VPATH and Make.
3881 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3882 * doc/standards.texi: Sync from gnulib.
3884 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3885 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3886 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3887 generated automatically.
3889 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3891 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3892 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3893 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3895 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3897 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3898 `CEOF$ac_eof' special marker, the awk script cannot contain a
3899 line matching `^CEOF', so this is not needed any more.
3900 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3901 special marker in the test.
3903 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3905 * tests/tools.at (autom4te preselections): Use `find -newer';
3906 remove one of the sleeps.
3908 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3909 more readable, using ...
3910 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3912 * doc/autoconf.texi (autoheader Invocation): Do not double-
3913 quote the parameter of `AH_BOTTOM' in the example.
3915 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3917 * doc/autoconf.texi (Configuration Headers): Remove the
3918 example with multiple input files.
3919 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3920 multiple input files.
3922 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3924 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3925 creating the awk substitution script, handle one input line at a
3926 time, so that the maximum length of a substituted (multi-line)
3927 value is not limited by the size of the sed pattern space.
3928 The trade-off is a slightly repetitive sed script.
3929 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3930 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3931 * tests/torture.at (Substitute a 2000-byte string): Increase the
3932 test with several long lines, they should not be caught by sed
3933 limits any more.
3935 * tests/tools.at (autom4te preselections): New test, to flag
3936 entries missing from autom4te.cfg.
3937 Report by David Byron <dbyron@hheld.com>.
3939 * tests/torture.at (Substitute a 2000-byte string): Actually use
3940 AC_PROG_AWK, so the last change works as intended.
3941 (Substitute and define special characters): Likewise.
3942 (Substitute a newline): Likewise.
3944 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3945 instead of `awk' consistently.
3946 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3947 * tests/torture.at (Torturing config.status): Test both the
3948 result of AC_PROG_AWK and plain awk.
3949 (Substitute a 2000-byte string): Likewise.
3950 (Substitute and define special characters): Likewise.
3951 (Substitute a newline): Likewise.
3953 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3955 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3956 can be assigned to a function pointer. Problem reported by
3957 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3958 part of a patch by Ralf Wildenhues in that same bug report.
3960 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3962 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3963 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3965 2006-12-01 Eric Blake <ebb9@byu.net>
3967 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3968 cross-compiling from cygwin to mingw.
3969 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3970 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3971 to lib/autoconf/c.m4.
3973 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3975 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3976 string for more reliable failure. Wrap the entire test that
3977 causes the broken Solaris printf to dump core, in a subshell,
3978 so the segmentation fault message is reliably suppressed.
3979 Fix shell expansion errors by using /usr/ucb/echo always;
3980 avoid an error on systems without it by another subshell.
3981 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3982 subshell-$as_echo to `as_echo', for better error message.
3984 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3986 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3987 `BASH_SOURCE' contain a newline, set them to empty, as they may
3988 not be unset.
3990 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3992 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3993 years and is too hard to maintain now. The last straw was
3994 reported by Jerker Baeck in
3995 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3996 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3997 * doc/autoconf.texi (Particular Functions): Move
3998 AC_FUNC_SETVBUF_REVERSED from here...
3999 (Obsolete Macros): ... to here. Say that it does nothing now.
4000 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4001 Turn into (almost) a no-op.
4003 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4004 (AC_C_VOLATILE):
4005 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4006 These macros are obsolescent and new applications shouldn't need them.
4007 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4008 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4009 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4010 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4011 (AC_FUNC_VPRINTF): Likewise.
4012 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4013 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4014 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4016 * doc/autoconf.texi (Setting Output Variables): Mention that
4017 @VAR1@VAR2 has unspecified behavior. Problem reported by
4018 Ralf Wildenhues.
4019 * NEWS: Mention this.
4021 * Makefile.am: Put only a single '#' into the copyright notice,
4022 so that it's also present in the output file. Standardize wording
4023 in makefile copyright notices to match GNU coding standards.
4024 * bin/Makefile.am: Likewise.
4025 * doc/Makefile.am: Likewise.
4026 * lib/Makefile.am: Likewise.
4027 * lib/freeze.mk: Likewise.
4028 * lib/autoconf/Makefile.am: Likewise.
4029 * lib/autoscan/Makefile.am: Likewise.
4030 * lib/autotest/Makefile.am: Likewise.
4031 * lib/m4sugar/Makefile.am: Likewise.
4032 * man/Makefile.am: Likewise.
4033 * tests/Makefile.am: Likewise.
4034 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4035 one-line file.
4037 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4039 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4040 in the sed script that mangles the awk script: delete up to the
4041 first exclamation mark only.
4042 * tests/torture.at (Substitute and define special characters):
4043 Test '!' too.
4045 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4047 Rewrite config files generation: avoid quadratic growth in
4048 the number of substituted variables by using awk instead of sed
4049 for the bulk of the substitutions.
4050 * NEWS: Mention this.
4051 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4052 forbidden in the output (and thus input) file.
4053 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4054 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4055 generate just one large awk script for substitutions,
4056 eliminating much of the earlier complexity, while adding some
4057 new complexity. Only expand the substitution templates at
4058 configure time, for smaller configure script size. If
4059 _AC_SUBST_FILES are used, test 'awk' for working getline support
4060 at config.status time. If absent, interpolate through the
4061 shell. The awk script was written with much help
4062 from Paolo Bonzini and Paul Eggert.
4063 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4064 (_AC_SED_FRAG_NUM): Likewise.
4065 (_AC_SUBST_CMDS): Renamed from...
4066 (_AC_SED_CMDS): ...this.
4067 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4068 * tests/torture.at (Substitute a 2000-byte string): Also
4069 substitute a line with 1000 words, and a variable with several
4070 long lines.
4071 (Substitute and define special characters): Test awk special
4072 characters, and put substitution input strings `@foo@' in the
4073 output, to test that no recursion happens; test several other
4074 combinations from Paolo Bonzini.
4076 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4078 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4079 that replaced echo with AS_ECHO where this wasn't necessary.
4080 Problem reportd by Ralf Wildenhues.
4081 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4082 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4083 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4085 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4087 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4089 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4091 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4092 that traditional Awk lacks 3-arg "split". It has it.
4093 Mention that FS must be a single character, and a few other
4094 99-byte limits of traditional Awk.
4095 Mention that if (i in a) doesn't work with traditional Awk.
4097 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4099 * tests/autotest.at (BSx641-newline in command):
4100 (BS-BS-newline in command, BSx640-newline in command):
4101 (Newline-CODE-BS-newline in command):
4102 (Single-quote-BS-newline in command):
4103 (Single-quote-newline-BS-newline in command):
4104 Use printf '%s\n' instead of echo, for portability to hosts
4105 where echo interprets backslashes. This will break on hosts
4106 that lack printf, but for now let's assume all such hosts
4107 are dead (if not, we should get reports of test failures).
4109 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4111 'echo' has some portability problems, when given a first argument
4112 with a leading '-', or when given any argument containing '\'.
4113 Avoid using 'echo' in these cases.
4114 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4115 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4116 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4117 * lib/autotest/general.m4 (AT_INIT): Likewise.
4118 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4119 argument might be unportable.
4120 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
4121 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

4123 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
4124 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
4125 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
4126 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
4127 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
4128 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

4134 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
4135 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.

4137 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
4138 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4139 * bin/autoconf.as: Redo verbose flag implementation, as the old
4140 scheme wouldn't work with AS_ECHO.
4141 * lib/autotest/general.m4 (AT_INIT): Likewise.
4142 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4143 Don't use ECHO_T, since ECHO_N is now reliable.
4144 * lib/autotest/general.m4 (AT_INIT): Likewise.
4145 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4146 rather than using a here-document to put the script into a file.
4147 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4148 use AS_ECHO.
4149 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4150 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4151 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4152 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4153 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4154 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4155 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4156 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4157 operand, as AS_ECHO requires. Avoid double file name expansion.
4158 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4159 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4160 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4161 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4162 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4163 Double-quote strings that would otherwise contain M4 comments.
4164 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4166 * configure.ac (AC_INIT): Bump to 2.61a.
4167 * NEWS: Likewise.
4169 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4171 Version 2.61.
4173 * configure.ac (AC_INIT): Bump to 2.61.
4174 * NEWS: Likewise.
4176 * tests/autotest.at (Macro with backslash in a test title):
4177 Comment out for now, as this tests neither fails nor passes
4178 reliably. Problem reported by Ralf Wildenhues.
4180 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4182 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4183 in previous change, which caused test failures.
4185 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4187 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4188 code for --enable, --disable, --with, and --without to...
4189 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4190 * doc/autoconf.texi (Package Options):
4191 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4193 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4195 Import these changes from config via gnulib:
4197 2006-11-15 Ben Elliston <bje@gnu.org>
4199 From Josselin Mouette <joss@debian.org>:

4230 Import these changes from texinfo via gnulib:
4232 2006-11-08 Karl Berry <karl@gnu.org>
4234 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
4235 as well as pdf images, since they are supported in pdftex with
4236 no further ado.
4238 2006-11-05 Karl Berry <karl@gnu.org>
4240 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

4252 first argument may also contain dots.
4254 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4256 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4257 benefit of platforms like Solaris+GCC where it is common to have a
4258 non-working g++ installation.
4260 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4261 and Joel E. Denny <jdenny@ces.clemson.edu>
4262 and Paul Eggert <eggert@cs.ucla.edu>
4264 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4265 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4266 ./micro-suite.
4268 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4270 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4271 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4272 Imported from a similar patch to gnulib by Bruno Haible.
4274 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

4293 and Stepan Kasal <kasal@ucw.cz>
4295 Handle special characters in test case titles correctly.
4296 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4297 properly.
4298 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4299 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4300 argument. Extend to check titles printed by ./micro-suite and
4301 ./micro-suite -l and the title in micro-suite.log.
4302 (Backquote in a test title,
4303 Single-quote in a test title,
4304 Double-quote in a test title): Don't expect failure anymore.
4305 (Backslash in a test title): Put a non-whitespace character after the
4306 backslash so that Bourne shells might actually see it as an escape
4307 sequence.
4308 (Brackets in a test title,
4309 Pound in a test title,
4310 Comma in a test title,
4311 Quoted Macro in a test title,
4312 Macro in a test title,

4315 Macro with double-quote in a test title,
4316 Macro with backslash in a test title): New tests expected to fail.
4317 * tests/torture.at (#define header templates): M4-quote this title in
4318 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4319 The visible effect was a stray [] in the testsuite output.
4321 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4323 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4324 `trap ... 0' inside a function, for AIX sh.
4326 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4328 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4329 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4330 5363) simply issues a warning when dividing by zero at compile
4331 time. Problem reported by Elias Pipping.
4333 2006-10-26 Eric Blake <ebb9@byu.net>
4335 * THANKS: Update.
4336 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4337 show effect on macros that expand with commas.
4338 Reported by Joel E. Denny.
4340 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

4362 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4364 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4365 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4366 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4367 reported by Nelson H. F. Beebe for Coreutils 6.4.
4369 * tests/tools.at (autoconf --trace: user macros): Remove test
4370 for tracing multiline macros, since m4 1.4.7a uses a different
4371 way to number lines. Problem reported by Ralf Wildenhues.
4373 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4375 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4376 /dev/null since the heuristics for interactive behaviour was
4377 fixed in CVS m4.
4379 * bin/autom4te.in: With --force, always refresh the output
4380 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4382 * bin/autoconf.as: Fix the verbose message at the end.
4384 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4401 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4402 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4404 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4406 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.

4433 looking for special shell characters.
4434 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4435 macro defined by AS_VAR_PUSHDEF before passing it as a
4436 parameter.

4447 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4449 (Imported from Automake.)
4450 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4451 which incorrectly sets the mode of an existing destination
4452 directory. In some cases the unpatched install-sh could do the
4453 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4454 system. We hope this is rare in practice, but it's clearly worth
4455 fixing. Problem reported by Alex Unleashed in
4456 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4457 Also, don't bother to check for -m bugs unless we're using -m;
4458 suggested by Stepan Kasal.
4460 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

4466 is enabled by default with gnu and gnits strictness.
4467 Report from Bruno Haible.
4469 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4470 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4471 gnu and gnits modes.
4473 Import this change from Config:
4475 2006-09-20 Ben Elliston <bje@gnu.org>

4478 Import this change from Gnulib:
4480 2006-09-16 Karl Berry <karl@gnu.org>
4481 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4482 to avoid sectioning errors.

4495 * build-aux/texinfo.tex (\textdegree): New command.
4497 2006-08-12 Karl Berry <karl@gnu.org>

4502 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4504 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4506 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4507 added to the template can get mangled.
4509 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4511 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4512 include the default headers, and redefine obstack_chunk_alloc
4513 and obstack_chunk_free. Fixes false failure with glibc.
4515 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4517 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4518 for backward compatibility with Libtool 1.5.22. Problem reported
4519 by Ralf Wildenhues.
4521 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4523 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4524 AC_PROG_CC.

4527 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

4532 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4534 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4535 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4536 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4537 Use a better substitute, by inspecting the output of "ls"
4538 rather than just using ":".
4539 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4540 rather than AS_EXECUTABLE_P, since we needn't worry about
4541 non-regular files here.
4543 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4544 due to configuration hassles with this. See Tonya Underwood's report
4545 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4546 * doc/autoconf.texi (Special Shell Variables): Likewise.

4554 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4556 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4557 initialization which is not inherited through the environment
4558 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4559 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4561 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4563 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4564 problems with mkdir -p -m.
4566 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4568 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4569 comment about ac_cpp_err; it was incorrect, and anyway
4570 ac_cpp_err is being removed below.
4571 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4572 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4573 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4574 nobody uses it.
4575 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4576 with werror_flag and conftest.err and so forth. This is more
4577 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4578 and anyway the user shouldn't normally want to see this gorp logged.
4579 Problem reported by Ralf Wildenhues.
4580 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4581 empty, not 'no', since the rest of the code uses 'test -z'.
4583 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4585 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4586 Use a single call to AC_DO_TOKENS rather than multiple, for
4587 efficiency.
4588 (_AC_LINK_IFELSE): Test that resulting file is executable.
4589 Problem reported by mwoehlke in
4590 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4592 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4593 than creating a file to use with test -x; this is much faster.
4595 2006-10-02 Bruno Haible <bruno@clisp.org>
4597 * lib/autom4te.in (Automake-preselections): Add
4598 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4600 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4602 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4603 standard error, `experr' should be used, not `expout'.
4605 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4607 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4608 fseeko testing program twice; just use the earlier result.
4609 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4610 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4611 still doesn't let the program compile.
4612 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4613 failed.
4615 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4616 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4617 include it, without including anything else.
4618 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4619 expressions.
4620 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4622 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4624 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4625 `error.h', and include it, for a `error_at_line' prototype.
4626 Use a nonempty format string in the link test.
4627 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4628 for a declaration of wait3.

4632 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4633 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4634 can apply to constants too, and that it checks for macro defns.
4635 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4636 and simply cast the identifier to void. This handles structure
4637 values. Problem reported by Ralf Wildenhues.
4638 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4640 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4695 --error-output, to avoid warnings with M4 2.0.
4697 2006-09-19 Stepan Kasal <kasal@ucw.cz>

4729 too late, anyway. Problem reported by Stefan Seefeld.
4731 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4732 7.1.4 /usr/bin/posix/sh described by Tim Rice in

4737 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4738 works with GNU M4 1.4.3 again; make the normalized form
4739 match the current m4 message; fix the description.
4740 * test/tools.at (autom4te cache): Adapt to the change.
4742 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
4744 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
4745 to catch glibc bug 2821
4746 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4748 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4749 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4750 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4751 assume C89.
4753 2006-09-08 Stepan Kasal <kasal@ucw.cz>
4755 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

4763 AM_ENABLE_MULTILIB.
4765 2006-09-05 Paul Eggert <eggert@cs.ucla.edu>
4767 * doc/autoconf.texi (Preset Output Variables): srcdir and
4768 top_srcdir are not necessarily relative. Problem reported
4769 by Dries Kimpe.
4771 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4773 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
4774 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
4775 accept files with extension `.f'. For consistency, also prefer
4776 xlf over f77.
4777 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
4778 from last patch.
4780 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

4793 before AC_PROG_FC, due to a bug in Autoconf.
4795 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
4797 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
4798 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
4799 except the first two arguments are reversed.
4800 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
4801 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
4802 caches nor outputs a diagnostic. Suggested by Bruno Haible.
4803 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
4804 equivalent to the old AC_COMPUTE_INT.
4805 (AC_COMPUTE_INT): No longer caches or reports. New signature.
4806 All uses changed to AC_CACHE_CHECK_INT.
4807 * tests/base.at (AC_CACHE_CHECK_INT): New test.
4808 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
4810 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
4812 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
4813 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
4814 programs should use their Gnulib counterparts.
4815 * doc/autoconf.texi (Particular Functions): Likewise.
4816 (Macro Names, testsuite Invocation): Replace uses of these
4817 obsolete macros with uses of non-obsolete macros.

4826 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Fix logic that was
4827 mistakenly swapped on 2006-08-15.
4829 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
4831 * NEWS: Version 2.60a.
4833 2006-08-25 Stepan Kasal <kasal@ucw.cz>
4835 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Remove the IPA/IPO
4836 file created by the PGI compiler.

4840 * lib/Autom4te/General.pm (END): Use `File::Path::rmtree' to
4841 simplify the code.
4843 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
4845 Fix Lex library problem reported to us by Julio Garvia.
4846 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
4847 for the default, which the user can override.
4848 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
4849 deal with LEXLIB.
4850 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4851 didn't work if some values were cached but not others. Test for
4852 broken lex libraries like native ia64-hp-hpux11.22; see
4853 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4854 work around the problem by preferring an empty LEXLIB to -lfl or
4855 -ll. Let the user set LEXLIB='' to indicate no library needed.
4857 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4858 * README: Likewise.
4859 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
4861 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>

4958 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4960 * doc/autoconf.texi (Particular Programs): Mention that
4961 @INSTALL@ and @MKDIR_P@ may vary for different output files.
4962 Reported by Alexandre Duret-Lutz.
4964 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
4966 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
4967 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
4968 Bill Northcott in
4969 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
4971 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>

4977 longer supported by Sun.
4979 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>

4982 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
4983 -Wundef -Werror". Problem reported by David Fang in
4984 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
4985 * doc/autoconf.texi (Header Templates, Default Includes):
4986 (Particular Functions, Generic Functions, Header Portability):
4987 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
4988 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

4992 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, _AC_FUNC_MALLOC_IF):
4993 (AC_FUNC_MKTIME, AC_FUNC_MMAP, _AC_FUNC_REALLOC_IF):
4994 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETVBUF_REVERSED, _AC_FUNC_VFORK):

4999 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5000 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
5001 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
5002 this.
5004 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
5006 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
5007 problems with arg script text that doesn't end in newline, and

5018 to last change.
5020 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5022 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
5023 --help' should mention that `--version' outputs configuration
5024 settings. Report by Bruno Haible.
5026 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
5028 Fix test suite failures reported by Pierre in
5029 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
5030 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
5031 the compiler created a file "b.out" when it didn't create anything
5032 at all.
5033 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
5034 Discard stderr too, when invoking the test script.

5044 less skeptical about "volatile", after discussion with
5045 Bruno Haible on bug-gnulib.
5046 (Limitations of Usual Tools): Warn about sed stripping
5047 leading white space from text. From Bruno Haible.
5049 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5051 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5052 compiler complains about it, even if things works after the
5053 complaint. Problem reported by Peter O'Gorman.
5055 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5056 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5057 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5059 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5061 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5062 after -R regardless of host. Patrick Welche reports that this
5063 fixes things on NetBSD 3.99.
5065 * NEWS: Recommend M4 1.4.5.
5066 * README: Likewise.
5067 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

5069 to match M4 1.4.5.
5071 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5073 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5074 under AC_C_VOLATILE.
5075 (Volatile Objects): Be a little less skeptical about what
5076 "volatile" means. Derived from thoughts by Ben Pfaff in
5077 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5079 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5081 * doc/autoconf.texi: Fix some typos.
5083 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5085 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5086 more globally, since the 2006-06-30 patch didn't suffice. Problem
5087 reported by Keith Marshall. Also, don't bother with builddir2,
5088 since it shouldn't be needed any more.
5090 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5092 * doc/autoconf.texi (Generic compiler characteristics):
5093 Document AC_COMPUTE_INT. Fix wrong statements on Default
5094 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

5107 * NEWS: Document previous change.
5109 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5111 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5112 Require that long long int be at least 64 bits wide. C99 requires
5113 this and enough programs depend on it so we should check for it.
5114 Bruno Haible reports in
5115 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5116 that long long int is 32 bits wide with some nonstandard compilers.
5117 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5119 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5121 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5122 to a nonexistent file, so that we don't have to worry about
5123 a local site configuration that doesn't use /usr/local.
5124 Problem reported by Keith Marshall in
5125 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5127 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5129 * doc/autoconf.texi: Be more consistent about using @acronym with
5130 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5131 quite right (it talked about "OSF/Tru64", even though the
5132 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5133 and it even mentioned "OSF 4"!) and at this point there's little
5134 reason to talk about OSF any more, since it died in 1994.
5135 (Specific Compiler Characteristics): Simplify example of
5136 negative-size array.
5137 (File Descriptors): Reorder to make the text flow better.
5138 Remove joke about "appreciate the various levels"; I didn't get it.
5139 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5140 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5141 (File Descriptors, Limitations of Usual Tools):
5142 Tone down the advice against renaming or removing open files.
5143 (Limitations of Usual Tools): Add a new section, on 'rm'.
5145 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5147 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5148 -lXt in LIBS, idea from Karsten Hopp; this was due since
5149 this change:
5151 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5152 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5153 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5154 (which belong to Xt, not X itself). See Debian bug 327655.
5156 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5158 * configure.ac (AC_INIT): Bump to 2.60a.
5159 * NEWS: Update.

5167 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5169 * config/texinfo.tex: Sync from upstream.
5171 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5172 quadrigraph correctly in traces.
5174 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5175 Fix typos.
5177 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5178 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5179 not defined.
5180 * doc/autoconf.texi (Changed Directory Variables): New node,
5181 to document the whole `datarootdir' business a bit better.
5182 * NEWS: Update.
5183 * tests/torture.at (datarootdir workaround): Extend test.
5184 Prompted by report by Alexandre Julliard.
5186 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5188 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5189 when using default mode of IBM C 6 for AIX. Problem and two-line
5190 fix reported by Larry Jones.
5192 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5194 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5195 about literal '${datarootdir}' if a definition is found in the
5196 output file.
5198 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5200 * NEWS: Use "M4" rather than "m4" when appropriate.
5201 Problem reported by Eric Blake.
5202 * doc/autoconf.texi: Likewise.
5203 Use @acronym around BSD, GCC, and GNU when appropriate.
5204 (Why GNU M4): Renamed from "Why GNU m4".
5205 (Redefined M4 Macros): Mention that Posix
5206 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5207 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5208 to int.
5210 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5212 * bin/autom4te.in (handle_output): Do not forbid the empty
5213 pattern.
5214 * tests/tools.at (autoconf: the empty token): New test.
5216 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5218 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5219 calls, so that we do not care whether they are LIFO or FIFO;
5220 in the m4_wrap, do not check which diversion is the topmost
5221 one, just check that the stack is balanced at the end.
5222 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5223 base diversion forever--pop the previous diversion before
5224 opening the new one; consequently, remove the m4_wrap call.
5225 * lib/autotest/general.m4 (AT_INIT): Likewise.
5226 * tests/m4sugar.at: Do not use
5227 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5229 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5230 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5232 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5233 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5234 Rework example of m4wrap token-pasting trouble so that it doesn't
5235 care whether it's LIFO or FIFO.
5236 Fix some "contrary to"s that are awkward in English.
5238 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5240 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5241 to `yes' instead of `int$1_t' if the type is found, for more
5242 consistent configure output (where $1 is the number of bits).
5243 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5244 Suggested by Bruno Haible.
5246 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5247 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5248 with system headers. Report by Bruno Haible.
5250 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5252 * config/config.guess, config/config.sub: Sync from upstream.
5254 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5255 in order to avoid picking up an older installed frozen m4sh.m4f.
5256 Besides an outdated shell startup, this could have been created
5257 by an earlier M4 version with incompatible frozen file format.
5259 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5261 * README: Recommend m4 1.4.4 instead of 1.4.3..
5262 * doc/autoconf.texi: Likewise.
5263 (Special Chars in Names): Say that $(.FOO) is portable, as
5264 suggested by Stepan Kasal.
5265 (Installation Directory Variables, Build Directories):
5266 (Automatic Remaking, Subdirectories, Fortran Compiler):
5267 (Making testsuite Scripts, Defining Directories):
5268 Quote variable usages better.
5269 (Making testsuite Scripts): Add clean-local rule to makefile
5270 snippet, by Eric Blake.
5271 (Installation Directory Variables): Fix table item font.
5272 Reword slightly to clarify. Generalize advice about
5273 not using special characters to include all file-related
5274 vars, not just VPATH.
5275 (Special Chars in Variables): Warn about special characters in
5276 $(srcdir) too.
5277 (Assignments): Clarify default-value example as suggested by
5278 Ralf Wildenhues in
5279 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5280 (Special Shell Variables): Note leading ./ or ../, as suggested
5281 by Eric Blake.
5282 (Limitations of Builtins): Under cd, warn about CDPATH.
5283 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5284 Ralf Wildenhues.
5286 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5288 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5289 `@var', for texi2html.
5290 (Systemology): Some more word wrapping, for DVI output.
5291 (autom4te Invocation): The short option for `--melt' is `-M',
5292 not `-m'.
5294 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5296 * doc/autoconf.texi: More formatting and English tweaks,
5297 many suggested by Ralf Wildenhues.
5298 Reword to avoid "@code{...}'s" and the like, since it's ugly
5299 with Emacs info mode. discontents -> woes.
5300 Put a few "will"s back. time stamp -> timestamp.
5301 side-effect -> side effect.
5303 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5305 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5306 Warn about $@ not persisting. Problem reported by Julien Danjou in
5307 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5308 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5309 Mention other special chars, too.
5311 2006-06-14 Eric Blake <ebb9@byu.net>
5313 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5315 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5317 * doc/autoconf.texi: Some systematic minor improvements, as
5318 follows. Use "makefile" when talking about makefiles
5319 generally (which might be named "makefile" or "Makefile" or even
5320 "foo.mk"), "Makefile" when talking about a specific makefile
5321 called "Makefile". This unclutters the text from weird quotes
5322 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5323 values" rather than "@var{foo}s" and similar constructs containing
5324 "}s". Use "Make rules" rather than "Makefile rules". Minor
5325 English-language improvements. Change the prefix "sub-" to "sub"
5326 and "re-" to "re".
5327 Put blank lines around examples more consistently.
5328 Avoid "rather" and "very" as intensifiers.
5329 Avoid "will" as an auxiliary.
5330 (Limitations of Make): Split this node into....
5331 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5332 (Leading _ in Macro Names, Backslash-Newline-Newline):
5333 (Backslash-Newline Comments, Long Lines in Makefiles):
5334 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5335 (obj/ and Make, make -k Status, VPATH and Make):
5336 (VPATH and Double-colon, $< in Explicit Rules):
5337 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5338 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5339 New nodes, resulting from splitup of Limitations of Make.
5340 All cross-references changed. Raise the top node from
5341 a section to a chapter, and all subnodes accordingly.
5342 Redo the introductory wording to match the new organization.
5343 (Installation Directory Variables): Use an example that is
5344 closer to what Autoconf actually does. Mention that VPATH's
5345 value should not contain metacharacters or white space.
5346 (Fortran Compiler): Fix a VPATH bug in an example.
5347 (Leading _ in Macro Names): Mention that this problem is no longer
5348 of practical concern.
5349 (VPATH and Make): Reword the advice to make it clearer
5350 that Autoconf and Automake support VPATH in non-GNU make, but
5351 many packages have bugs in this area.
5352 ($< in Explicit Rules): Refer to Build Directories rather
5353 than using a (non-VPATH-safe) example.
5354 (Automatic Rule Rewriting): Mention the sort of disaster that
5355 can ensue with Solaris-style rule rewriting with VPATH.
5357 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5359 * doc/install.texi (Compilers and Options): Weaken the
5360 suggestion to use GNU make for VPATH builds.
5362 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5363 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5365 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5366 in regular expression.
5368 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5370 * doc/autoconf.texi (Installation Directory Variables):
5371 Drop extra @samp from `@table @samp' item.
5372 (Limitations of Usual Tools): Comment fix.
5373 Do not nest @samp just to point to other table items.
5374 (Writing testsuite.at) <AT_CHECK>: The second argument to
5375 `@dvar' is already @samp'ed.
5376 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5377 do not use @var in the second argument.
5379 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5381 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5382 $as_shell.exe too. Problem reported by Andreas Buening in
5383 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5385 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5387 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5388 `unused variable' compiler warning, for `-Wall -Werror'.
5389 Reported by Jaap Haitsma in
5390 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5392 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5394 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5395 case the compiler dumps core. Problem reported for
5396 OpenServer 5.0.7 by Tim Rice in
5397 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5398 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5399 Likewise.
5401 2006-06-06 Tim Rice <tim@multitalents.net>.
5403 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5404 "ERROR" only shows up in "make check" output if there is an
5405 error.
5407 2006-06-06 Eric Blake <ebb9@byu.net>
5409 * tests/tools.at (automatically allowed tokens): Fix typo.
5411 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5413 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5415 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5416 typically overflows on x86 CPUs, even though the C standard
5417 requires otherwise.
5419 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5421 * configure.ac (AC_INIT): Bump to 2.59e.
5422 * NEWS: Update.
5424 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5426 Version 2.59d.
5428 * config/texinfo.tex: Sync from upstream.
5430 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5431 seen, invoke libtoolize with `--ltdl' argument.
5432 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5433 * NEWS: Update.
5434 Suggested by Eric Blake.
5436 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5438 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5439 reported by Ralf Wildenhues.

5455 * tests/base.at: Check AC_REQUIRE's error message.
5456 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5457 to...
5458 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5459 AT_CHECK_M4.
5460 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5461 `expout' as the last parameter.
5462 * tests/tools.at: Adapt to the above change.
5464 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5466 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5467 information about race-free implementations of mkdir.
5469 2006-06-04 Eric Blake <ebb9@byu.net>
5471 * bin/autoreconf.in (help): Document M4 environment variable.
5472 * bin/autoconf.as (Usage): Likewise.
5473 * bin/autom4te.in (help): Likewise.
5474 * doc/autoconf.texi (autom4te Invocation): Likewise.
5476 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5478 * NEWS: GNU make now recommended for VPATH builds.
5479 Mention that some macros are now documented to be obsolescent.
5480 * doc/autoconf.texi:
5481 Prefer "current" to "modern" to describe
5482 currently-used (albeit perhaps old-fashioned) hosts.
5483 Mention which ancient features no longer need to be worried about.
5484 setgid -> set-group-ID
5485 setuid -> set-user-ID (these are the Posix terms)
5486 Fix some misuses of "only".
5487 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5488 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5489 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5490 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5491 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5492 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5493 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5494 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5495 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5496 Mention that these macros are obsolescent.
5497 (Installation Directory Variables): shall -> should
5498 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5499 Mention that it's now safe to use 3 and 4.
5500 (Limitations of Usual Tools): cp -r is now specified by Posix.
5501 Omit longwinded and obsolescent discussion of cp -f.
5502 Modernize discussion of expr, ls.
5503 (Limitations of Make): Modernize discussion of VPATH builds.
5504 Mention $? as a workaround in some cases.
5505 * doc/install.texi (Basic Installation):
5506 Mention "./configure; make; make install" first. Be more
5507 specific about why this file is generic. Remove unnecessary
5508 parens. Remove misleading "only". Remove obsolete advice
5509 about csh. Don't say "configure" takes awhile; say it
5510 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5511 and CC=c99 rather than CC=c89, as these are blessed by current
5512 Posix. Recommend GNU make if doing a VPATH build.
5514 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5516 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5517 examples involving shell prompts.
5519 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5520 and Paul Eggert <eggert@cs.ucla.edu>
5522 * doc/autoconf.texi (Here-Documents): Add details about the
5523 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5524 use "here-documents" instead of "here documents".
5526 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5528 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5530 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5532 * doc/autoconf.texi (File System Conventions): Warn about ":"
5533 anywhere in directory names.
5535 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5537 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5538 about quoting the case statement, just in case.
5539 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5540 was fixed in ksh93g; reported by Ralf Wildenhues.
5542 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5544 * doc/autoconf.texi (System Services): Do not document
5545 overriding EXEEXT via ac_cv_exeext=ext.

5547 Document that ${MKDIR_P} understands --.
5548 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5549 comment.
5551 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5553 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5554 argument with leading hyphen. Problem reported by Paul Eggert.
5556 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5558 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5559 about quoting ac_try: quote all of it, if any of it seems suspicious.
5560 This means we don't have to worry about ${ or sed any more.
5561 Also, double-quote the case statement, to work around misuses via
5562 underquoting as reported by Ralf Wildenhues in
5563 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5564 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5565 undocumented and dangerous macro.
5566 Problem reported by Ralf Wildenhues in
5567 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5569 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5573 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5575 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5577 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5578 since evidently some packages rely on the old, broken behavior.
5579 Problem reported by Ralf Wildenhues in
5580 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5581 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5582 pre-2006-05-26 definitions, but leave in the comments that
5583 these macros are dangerous and should not be used.
5584 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5585 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5586 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5587 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5588 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5590 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5592 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5593 the use of 'tr', since this is our only use of 'tr'.
5595 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5596 and Paul Eggert <eggert@cs.ucla.edu>
5598 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5599 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5601 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5603 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5604 the output file in the `${datarootdir}' test.
5606 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5607 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5609 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5610 mention of `datarootdir' in the input file(s), but literal
5611 `${datarootdir}' in the output file, and we haven't warned yet,
5612 then warn as well: the user may have (erroneously) used
5613 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5614 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5615 * tests/torture.at (datarootdir workaround): Extend this test.
5616 * NEWS: Update.
5618 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5619 and Paul Eggert <eggert@cs.ucla.edu>
5621 * doc/autoconf.texi (autoheader Invocation): The first argument to
5622 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5623 alternatives and clear up the language a bit.
5625 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5627 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5628 ac_config_guess, ac_config_sub, ac_configure.
5629 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5630 Fix typo that prevented an unnecessary space from being removed.
5631 Problems reported by Ralf Wildenhues in:
5632 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5634 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5636 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5637 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5638 Don't use the term "thread-safe" to talk about mkdir race
5639 conditions, since the problem is more a process than a thread
5640 issue. Problem reported by Stepan Kasal in:
5641 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5642 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5643 the test for 'install' more closely. Look at MKDIR_P first.
5644 Look in the PATH, and at /opt/sfw/bin.
5645 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5646 Don't bother to try mkdir -p, since we already check mkdir --version;
5647 just look at the version number. (There's no easy way to check
5648 for race-free implementations.)
5649 * tests/tools.at (autoconf: subdirectories): Adjust to above
5650 changes, since MKDIR_P now might end in "/mkdir -p".
5652 * doc/autoconf.texi (autoheader Invocation): Mention that the
5653 first arg of AC_DEFINE_UNQUOTED must be a literal.
5654 Problem reported by Ben Pfaff in
5655 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5657 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5658 * doc/autoconf.texi (Special Chars in Variables): New section.
5659 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5660 (Installation Directory Variables): Quote $(datadir) better.
5661 (Limitations of Builtins): Describe some of eval's trickiness.
5663 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5664 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5665 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5666 in front of every arg, not just trailing args. Quote apostrophes.
5667 (_AC_EVAL_ECHO): New macro.
5668 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5669 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5670 removed.
5671 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5672 exposed by quoting of eval argument. Put the command on line line
5673 so it logs better.
5674 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5675 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5676 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5677 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5678 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5679 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5680 Use eval more safely.
5681 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5682 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5683 to be replaced.
5684 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5685 lines, exposed by quoting of eval argument.
5687 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5688 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5690 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5691 initialization of `ac_cv_exeext', do not override it if it was
5692 already set, unless it was set to `no', for compatibility with
5693 Autoconf-2.13, and comment this.
5694 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5695 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5696 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5697 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5698 Document that this test may be overridden by setting
5699 `ac_cv_exeext'.
5701 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5703 Revert these two patches:
5705 2006-04-06 Eric Blake <ebb9@byu.net>
5706 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5707 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5708 2006-04-01.
5710 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5711 Clean up _AC_COMPILER_EXEEXT* macros.
5712 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5713 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5714 ac_file to the name of the default output file and call
5715 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5716 initial `rm' of the candidate files...
5717 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5718 the same list in subsequent `rm' calls, and for the temporary
5719 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5720 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5721 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5722 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5723 no longer needed) by libtool. Make it a cache check.
5724 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5725 copied here by mistake.
5726 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5727 _AC_COMPILER_EXEEXT.
5728 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5729 _AC_COMPILER_OBJEXT directly.
5730 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5732 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5734 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5735 Fix description of how the buggy `sed' works.
5737 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5739 Sync from Automake:
5741 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5742 ENOLCK. Only mention `make -j' when applicable. Only raise
5743 fatal errors when `make -j' is involved. Improve error message.
5745 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5747 * doc/autoconf.texi (Here-Documents): We now know more about
5748 the variable expansion in here documents bug.
5749 Thanks to Tim Rice and Stepan Kasal.
5751 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5752 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5754 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5756 * tests/autotest.at (Multiline command from M4 expansion):
5757 No failure to be expected if the shell quotes newlines in
5758 commands in the `set -x' output. Report by Tim Rice.
5759 * THANKS: Update.
5761 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5763 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5764 expansion in the here-documents used by config.status, as that
5765 runs afoul of the Korn shell version M-12/28/93d bug described in
5766 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5767 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5768 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5770 2006-05-23 Jim Meyering <jim@meyering.net>
5772 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5773 Fix typo introduced with 2006-04-02 change. It reversed the sense
5774 of the test.
5776 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5778 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5779 ac_dB slightly, to save bytes in the script.
5780 Max out at 50 lines, rather than 96; this is more likely
5781 (though not guaranteed) to avoid obscure 'sed' failures.
5783 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5785 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5786 `tr -d -' as bad option argument. Work around this by deleting
5787 an unrelated character.
5788 Report by Tim Rice <tim@multitalents.net>.
5790 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5791 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5792 Stepan Kasal <kasal@ucw.cz>
5794 * doc/autoconf.texi (Particular Programs): Do not promise that
5795 we always prefer the GNU version of the program, and that we
5796 search according to PATH; both rules can have exceptions.
5797 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5798 AC_PROG_SED. Move descriptions of limitations
5799 to the Limitations of Usual Tools section.
5800 (Limitations of Usual Tools) <sed>: Mention script length
5801 limitations with Solaris /usr/ucb/sed.
5802 <grep>: Fix wording for empty alternative. Mention that -c and
5803 -l should not be combined, and that -E and -F should not be
5804 combined.
5806 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5807 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5809 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5810 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5812 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5814 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5815 AC_DEFINE is now passed to m4_pattern_allow.
5816 * NEWS: Mention that; likewise for AC_SUBST.
5817 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5818 the parameter to m4_pattern_allow.
5819 * tests/tools.at: Add a check for that.
5821 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5823 * lib/autoconf/status.m4: Fix typos.
5825 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5827 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5828 only the files that this macro generates.
5830 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5832 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5833 the HP-UX sed limitation of 99 commands, labels do not count.
5834 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5835 in the comment.
5836 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5838 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5840 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5841 Import the following fix from coreutils:
5843 2006-01-13 Jim Meyering <jim@meyering.net>
5845 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5846 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5847 not double-quote uses of that variable, to accommodate the rare
5848 case in which getmntent is available in none of the libraries
5849 checked. This happens at least on FreeBSD 5.0.
5851 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5853 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5854 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5855 some other programs unwisely rely on these undocumented vars.
5856 But put in warning comments about them.
5857 Problem reported by Ralf Wildenhues in
5858 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5859 * NEWS: Document that these variables are intended to go away.
5861 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5863 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5864 and set the language to C++ (analogous to the equivalent Fortran
5865 tests).
5867 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5868 * doc/autoconf.texi (C++ Compiler): Document it.
5869 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5870 * NEWS: Update.
5872 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5874 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5875 that caused config.status to generate 100-command sed scripts; the
5876 portable limit is 99.
5878 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5880 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5881 variable `ac_d' instead of `d' to avoid infringing namespace.
5882 Report by Ralf Menzel.
5884 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5886 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5887 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5888 * tests/tools.at (autoconf: subdirectories): New test, taken from
5889 the corresponding problem report by Ralf Wildenhues in:
5890 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5892 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5893 Quote some uses of shell variables if they might suffer unexpected
5894 globbing. This doesn't fix all instances of quoting problems that
5895 I found, just the easy ones that look safe.
5896 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5897 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5898 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5899 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5900 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5901 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5902 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5903 Likewise.
5904 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5905 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5907 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5909 * bin/autoreconf.in ($help): Reword according to the manual.
5910 Suggested by Olly Betts.
5912 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5913 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5915 * bin/autoreconf.in: Pass the directory argument to
5916 `require_configure_ac'. Fix comment.
5917 * tests/torture.at (Configuring subdirectories): Expose this.
5918 Reported by Olly Betts.
5920 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5922 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5923 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5924 Automake as follows:
5926 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5927 `$configure_in' instead of `configure.in', to preserve
5928 directory component.
5930 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5932 * config/config.guess, config/config.sub, config/texinfo.tex,
5933 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5935 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5937 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5938 test for C99 conformance; (bool) 0.5 is an integer constant
5939 expression, but (bool) -0.5 is not. Problem reported by Fedor
5940 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5942 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5944 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5945 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5946 Warn about obsolete install-sh files. Remove stray sentence
5947 fragment and fix cross reference.
5948 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5949 install -d; this undoes the 2006-05-10 change.
5950 (MKDIR_P): Mark with AN_MAKEVAR.
5951 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5952 that we don't require $INSTALL to be thread-safe. Move comments
5953 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5954 of AC_PROG_INSTALL. Output a message saying that we're checking
5955 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5956 MKDIR_P instead of AC_SUBST.
5957 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5958 Special magic for MKDIR_P, too.
5959 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5960 a dnl.
5961 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5963 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5965 Sync from Automake, as follows:
5967 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5968 * config/install-sh: Initialize IFS, so field splitting isn't
5969 turned off later.
5970 * config/mkinstalldirs: Likewise.
5971 * config/missing: Remove superfluous quotes. Replace all uses of
5972 `[' by `test', for consistency, and for..
5973 * config/missing (sed_minuso, sed_output): New variables.
5974 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5975 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5976 Fixes `missing' to detect `--output' for help2man. Fixes
5977 PR automake/483. Report by Dennis J. Linse.
5978 (autom4te): Document in `missing --help'.
5980 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5982 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5983 * config/install-sh: Don't use 'path' to talk about file names,
5984 as per GNU coding standards. Close a race condition reported by Ralf
5985 Wildenhues and Stepan Kasal. There is still a race condition
5986 on hosts that predate Posix 1003.1-1992, but we can't help this.
5987 Don't mishandle weird characters like space on pre-Posix hosts.
5988 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5989 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5990 AC_PROG_MKDIR_P from AS_MKDIR_P.
5991 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5992 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5993 earlier editions are not (including Automake 1.8.3).
5994 Do not suggest mkinstalldirs for thread-safety.
5995 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5996 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5997 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5998 presence of special characters and race conditions.
5999 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6000 in Autoconf's name space.
6002 2006-05-10 Bruno Haible <bruno@clisp.org>
6003 and Paul Eggert <eggert@cs.ucla.edu>
6005 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6006 from Automake with minor changes.
6007 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6009 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6011 * config/install-sh: Update to Automake CVS version, as follows:
6012 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6013 * lib/install-sh: Simplify the expr implementation of dirname.
6014 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6015 * lib/install-sh: Handle --, and diagnose unknown options.
6017 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6019 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6020 `./autom4te' to create `./testsuite', since the `all' target
6021 will ensure its presence, but `installcheck' should not create
6022 the uninstalled wrappers.
6024 * tests/torture.at (Unusual Automake input files): Skip if we
6025 detect automake < 1.8.
6027 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6029 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6030 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6031 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6032 * NEWS: Update.
6034 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6036 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6037 munge (multiple) white space and other oddities.
6038 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6039 single quotes in variable assignment.
6040 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6041 and similar failures by adding multiple spaces, tabs, and other
6042 special characters.
6043 Report and different test suggested by Francesco Romani
6044 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6046 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6047 single quotes, we only need to search for single quotes; this
6048 both simplifies the search pattern, and makes us less
6049 susceptible to `echo' variations for arguments not containing
6050 single quotes.
6051 (_AC_ARG_VAR_VALIDATE): Likewise.
6053 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6055 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6056 `$*' and IFS concatenation issue with traditional shells and

6069 and Bruno Haible <bruno@clisp.org>
6071 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6072 about 'od'.

6074 overflow.
6076 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6078 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6079 traditional shells like the Solaris one that do not use the
6080 first IFS character for assembling `$*'.
6081 Prompted by a related report from autoconf_bug@nro.ca.
6083 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6084 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6086 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):

6127 (Integer Overflow, Null Pointers, Buffer Overruns):
6128 (Floating Point Portability, Exiting Portably): New sections.
6129 (Writing Test Programs): Fix some langauge. Recommend exiting
6130 with status 1, not merely nonzero. Clarify exit declaration.
6131 (Run Time): Move C exit status stuff to new Exiting Portably section.
6132 (Systemology): Mention Posix and levenez. Update v7 reference.
6133 (Portable Shell): Mention the Posix shell.
6135 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6137 * bin/autoconf.as (me): Replace by as_me.
6139 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6141 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6142 since as_me isn't set yet.
6144 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6146 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6147 a few minor bugs in this area.
6149 * doc/autoconf.texi (Programming in M4sh): Comment out the
6150 documentation of AS_BASENAME, for now.
6151 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6152 (Limitations of Builtins) <basename>: Do not refer to
6153 AS_BASENAME.
6154 * bin/autoconf.as (me): Don't use AS_BASENAME.
6155 (dir): Remove the unused variable.
6156 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

6176 * lib/autoconf/general.m4: Likewise.
6177 * lib/autoconf/headers.m4: Likewise.
6179 * doc/autoconf.texi (Run Time): Document the exit status situation
6180 with more accuracy and detail.
6182 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6184 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6185 Archive is not officially `GNU' any more. Update URL.
6186 (Defining Directories): Likewise
6187 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6189 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6191 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6192 newline from the `trap' code to finish `config.log'; the NetBSD
6193 /bin/sh resets the exit status after an empty command, as
6194 documented in doc/autoconf.texi.
6195 Reported by Dalibor Topic <robilad@kaffe.org>.
6197 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6199 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6200 Suggested by Bruno Haible.
6202 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6204 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6205 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6206 Instead, just list the shells that we know work.
6207 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6208 changed. Be more cautious about the _cv_ variable.
6209 * tests/tools.at (Syntax of the shell scripts): Check the
6210 _cv_ variable once, at first, to avoid an internal autoconf error
6211 when sh -n does not work.
6213 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6215 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6217 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6219 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6220 use ">&-" since we're only 99.999% sure that this is portable,
6221 and since the MinGW bug is fixed in a different way.
6222 * lib/autotest/general.m4 (AT_INIT): Likewise.
6224 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6226 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6227 before opening config.log, to avoid hitting a bug on MinGW.
6229 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6231 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6232 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6233 This works around a MinGW bug reported by Eric Paire.
6234 Make sure that all writes to the log file append to it,
6235 rather than possibly losing data.
6236 * lib/autotest/general.m4 (AT_INIT): Likewise.
6238 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6240 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6241 description.
6243 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6245 * NEWS: Update.
6247 * configure.ac (AC_INIT): Bump to 2.59d.
6249 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6251 Version 2.59c.
6253 * Makefile.maint (news-date-check): Do not require a leading `*'
6254 before the release date in NEWS.
6256 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6257 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6260 the instantiated file do not contain the string 'datarootdir'
6261 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6262 @mandir@, replace the reference '${datarootdir}' by the value.
6263 * tests/torture.at (datarootdir workaround): New test.
6264 * NEWS: Advertise this temporary fixup.
6265 Based on a patch by Bruno Haible, reported and analyzed by
6266 Paul Eggert and Noah Misch.
6268 2006-04-12 Eric Blake <ebb9@byu.net>
6270 * tests/autotest.at (Debugging a failed test): Fix comment.
6272 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6274 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6275 all the changes since 2006-04-07.
6277 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6279 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6280 succeeded, but `ln -s file dir' failed, take care to remove the
6281 leftover target before the next test, to prevent its spurious
6282 failure; also make sure `ln file dir' works before selecting it.
6283 Thanks to Keith Marshall for pointing this out.
6284 * THANKS: Update.
6286 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6287 assignments in `at_debug_args', so that we put them correctly
6288 in the `run' script.
6289 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6290 Reported by Eric Blake.
6292 2006-04-11 Eric Blake <ebb9@byu.net>
6294 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6295 top-level tests after micro-suite has been run. Used in...
6296 (Debugging a successful test, Debugging script and environment),
6297 (Debugging a failed test): ...these new tests. The first of these
6298 is fixed by...
6299 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6300 macro, split out from...
6301 (AT_INIT): ...here, so that using -d also generates a run script.
6302 Document that -d inhibits top-level logging.
6303 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6304 inhibits top-level logging; debug scripts are created.
6306 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6307 check.
6308 * tests/autotest.at (Empty test, Empty check): New test to check it.
6310 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6311 from gcc.
6313 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6315 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6316 the files if a problem appears. Make the empty *.at files
6317 read-only, too. Proposed by Ralf Wildenhues.
6319 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6321 * config/Makefile.am: Add comment to force updated Makefile.in.
6323 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6324 space only patch to this file, this patch causes the Makefile.in
6325 files that include freeze.mk to be updated, and thus have a
6326 newer time stamp again, which in turn makes a pristine CVS
6327 checkout have correct time stamps.
6329 * Makefile.maint (cvs-sv): New macro, to be used..
6330 (config.guess-url_prefix, config.sub-url_prefix)
6331 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6332 point to CVS text checkout of Gnulib files.
6333 (copyright-check): Bump current year.
6334 (announcement): Do not hard-wire `./announce-gen'.
6335 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6336 correctly.
6337 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6338 `chmod +x'.
6339 (wget_files): Update config.guess, config.sub, texinfo.tex by
6340 `wget-update', now that their URLs work again.
6342 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6344 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6345 Problem noted by Paul D. Smith.
6347 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6349 * doc/autoconf.texi: Remove unused words from word list.
6350 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6351 .x-sc_trailing_space: New files.
6353 * doc/standards.texi: Sync from gnulib.
6355 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6356 `LIBOBJDIR' as experimental.
6358 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6359 with a target directory; it's internally implemented as `cp'
6360 anyway, but since Autoconf advertises the possibility to use
6361 a target directory when LN_S is `ln -s', we need to find out.
6362 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6363 analyzed by Keith Marshall <keith.marshall@total.com>.
6365 * THANKS: Update.
6367 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6369 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6370 confdefs.h as-is. In general, if it has backslash-newline or the
6371 like, then it doesn't work either to sort or to remove empty
6372 lines.
6374 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6376 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6378 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6380 * lib/autom4te.in (Automake-preselections): Preselect
6381 _AM_SUBST_NOTMAKE.
6383 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6385 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6386 apostrophe within a single-quoted string, as this is the usual
6387 tradition and is easier to read than '"'"'. Don't rely on the
6388 shell treating "$/" like '$/'. Use a more-consistent indenting
6389 style for the trap.
6391 2006-04-09 Eric Blake <ebb9@byu.net>
6393 * tests/autotest.at (Backquote command substitution),
6394 (Multiline backquote command substitution): Remove mistaken
6395 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6396 applied...
6397 (Parenthetical command substitution, Multiline parenthetical
6398 command substitution): here.
6400 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6402 Import macros from gnulib (often changing their name).

6416 (Pointers): Add Gnulib URL.
6417 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6418 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6419 Gnulib section.
6420 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6421 suggest a #define rather than a typedef for _Bool, and mention
6422 Gnulib rather than trying to substitute stdbool code.
6423 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6424 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6425 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

6428 headers too.
6429 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6430 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6431 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6432 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6433 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6434 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6435 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6436 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6437 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6438 (Coding Style). Don't mention m4_expand_once.

6440 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6441 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6442 (AC_CHECK_FUNCS): Use it.
6443 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.

6446 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
6447 (AC_HEADER_ASSERT): New macro.
6448 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6449 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6450 Catch a bug in an HP-UX C compiler.
6451 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6452 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6453 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

6456 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6457 New macros.
6459 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6460 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6462 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6464 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6465 of the warning introduced by the 2001-08-28 change.
6467 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6468 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6470 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6471 variables shall be overriden by the cache.
6472 * tests/torture.at (AC_ARG_VAR): Test also with a first value
6473 that contains braces.
6475 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6477 Revert the patch from 2006-04-01 and only improve
6478 _AS_DETECT_BETTER_SHELL:
6480 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6481 skip nonexistent directories.
6482 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6483 only shell candidates which exist.
6484 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6485 * lib/autotest/general.m4 (AT_INIT): No need to give three
6486 parameters to _AS_PATH_WALK.
6488 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6489 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6491 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6492 distinguish m4sugar macros.
6493 * tests/tools.at (autoupdating with aclocal and m4_include):
6494 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6495 test case by Noah Misch <noah@cs.caltech.edu>.
6497 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6499 Revert my change from 2006-03-17, in other words:
6500 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6501 and DUALCASE=1.
6502 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6503 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6504 it is set.
6506 2006-04-07 Eric Blake <ebb9@byu.net>
6508 * doc/autoconf.texi (Programming in M4sh): Document that
6509 AS_MKDIR_P exits the script on failure.
6510 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6512 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6514 * config/elisp-comp, config/install-sh, config/mdate-sh,
6515 config/missing, config/mkinstalldirs: Sync from Automake.
6517 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6518 from Automake.
6520 * doc/make-stds.texi: Sync from gnulib.
6522 2006-04-06 Eric Blake <ebb9@byu.net>
6524 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6525 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6526 2006-04-01.
6528 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6529 Eric Blake <ebb9@byu.net>,
6530 Paul Eggert <eggert@cs.ucla.edu>,
6531 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6533 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6534 whether `set' quotes correctly: redirect stderr of the tested
6535 `set', and use a subshell, for Ultrix; use `sed' instead of
6536 `grep' for zsh `set' which may write binary output; match only
6537 at the beginning of a line, to avoid false positives.
6538 In order to avoid false positives by unrelated variables with
6539 multiline content, put the dump algorithm in a subshell and
6540 unset all variables containing newlines (except some which are
6541 special to the shell). Warn about cache variables that are
6542 unset.
6544 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6546 * config/config.guess, config/config.sub, config/texinfo.tex:
6547 Sync from upstream.
6549 * tests/mktests.sh: Reword comments.
6551 * tests/mktests.sh: Only skip internal macros starting with
6552 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6553 Update exclusion lists for the test suite to this end:
6554 (AC_ARG_VAR): Do test this now.
6555 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6556 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6557 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6558 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6560 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6561 shell issue with double-quoted command substitutions of native
6562 commands.
6563 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6564 Marshall.
6566 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
6567 no file matches the glob, discard the warning, set `nullglob'.
6568 (syntax-check): Likewise.
6569 (sc_cast_of_x_alloc_return_value): Likewise.
6570 (sc_cast_of_alloca_return_value, sc_error_exit_success)

6578 * lib/autoconf/status.m4: More replacements to
6579 <tab><space> where this makes sense.
6581 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6583 * tests/Makefile.am (maintainer-check-posix):
6584 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6586 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6587 ac_config_<foo>s again, sometimes normalized, sometimes not.
6588 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6589 (AC_CONFIG_COMMANDS): Do not do so here.
6590 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6591 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6592 2005-07-25 rewrite. Noticed by Noah Misch.
6594 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6595 _AC_PRESERVE_HELP_ORDER, ...
6596 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6598 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6599 inside m4_expand_once; it is redundant.
6601 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6602 for --help from Cygnus `configure.'
6604 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
6606 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
6607 on a patch proposed by Ralf Wildenhues.
6609 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6611 * lib/autoconf/status.m4: Replace <space>''<tab> with
6612 <tab><space> where this makes sense.
6614 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
6615 Noah Misch <noah@cs.caltech.edu>
6617 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6618 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6619 * doc/autoconf.texi (Help Formatting): New node.
6620 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6622 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6624 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6625 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6626 lib/autoconf/types.m4, lib/autotest/general.m4,
6627 tests/mktests.sh, tests/torture.at: White space cleanup:
6628 remove some SPACE before TAB, or add quoting ('' or @&t@).
6630 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6632 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
6634 2006-04-05 Eric Blake <ebb9@byu.net>
6636 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
6637 empty test suite works.
6638 * tests/autotest.at (Empty test suite): Remove xfail.
6640 2006-04-05 Noah Misch <noah@cs.caltech.edu>
6642 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
6643 TAGS to ac_config_<foo>s.
6644 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
6645 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
6646 normalizing it, consistent it with previous releases.
6647 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
6649 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6651 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
6652 Use simplified args that Eric Blake originally suggested.
6654 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6656 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6657 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6658 Use 'comm' rather than N instances of grep; this also fixes a bug
6659 whereby substrings were incorrectly matched, causing us to not
6660 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6661 (exclude_list): Exclude empty macros.
6662 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6664 Use awk rather than grep -E or egrep, to avoid
6665 portability problems with regular expressions containing newlines.

6667 Switch from grep to awk syntax.
6668 (ac_exclude_script): Renamed from ac_exclude_egrep.
6669 (au_exclude_script): Renamed from au_exclude_egrep.
6671 2006-04-04 Noah Misch <noah@cs.caltech.edu>
6673 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
6674 a subdirectory subject to Cygnus `configure'.
6675 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
6677 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
6678 report request when we have no AC_PACKAGE_BUGREPORT.
6680 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6682 * THANKS: Update.

6685 generated files.
6687 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
6688 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
6689 typedef'ed restricted pointer, to catch a compiler bug on
6690 HP-UX 11.x, and fix warnings so it passes with -Werror.
6691 (_AC_PROG_CC_C99): Likewise.
6692 Reported by Albert Chin <china@thewrittenword.com>.

6708 * THANKS: Add myself.
6710 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6712 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
6713 to log, point to testsuite output tree.
6715 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
6717 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
6718 * doc/autoconf.texi (Function Portability): Mention that C++
6719 has trouble with 'exit'.
6720 (Guidelines): Test programs shouldn't use 'exit'.
6721 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6722 Remove; all uses removed.
6723 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

6743 Clean up _AC_COMPILER_EXEEXT* macros.
6745 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6746 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6747 ac_file to the name of the default output file and call
6748 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6749 initial `rm' of the candidate files...
6750 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6751 the same list in subsequent `rm' calls, and for the temporary
6752 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6753 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6754 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6755 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6756 no longer needed) by libtool. Make it a cache check.
6757 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6758 copied here by mistake.
6759 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6760 _AC_COMPILER_EXEEXT.
6761 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6762 _AC_COMPILER_OBJEXT directly.

6789 and fix some typos.
6791 2006-04-01 Noah Misch <noah@cs.caltech.edu>
6793 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
6794 Autoconf version number despite a zero- or one-argument AC_INIT.
6796 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
6797 subordinate tools.
6798 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6799 * doc/autoconf.texi (autoreconf Invocation): Document it.
6801 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
6802 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.
6804 2006-04-01 Eric Blake <ebb9@byu.net>
6806 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Allow use in shell lists.
6807 * lib/autotest/general.m4: Be tolerant of existing directory when
6808 rm failed to remove it.
6810 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6812 * bin/autoupdate.in: Redefine m4_location so that warnings print
6813 the correct lines of the input file by subtracting..
6814 (_au__first_line): ..this new definition.
6816 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
6817 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
6818 Remove stray newline in output.
6819 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
6820 AC_DEFUN this for autoconf, including the obsoletion diagnose.
6821 Fixes autoupdating of code where the replacement output contains
6822 m4sugar macros.
6823 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
6824 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

6826 * tests/tools.at: Several new tests for all of this.
6827 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
6828 hairy details.
6829 The AC_LANG_SAVE issue was reported against Libtool by
6830 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
6831 Kristian Kvilekval <kris@cs.ucsb.edu>.
6833 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6835 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6836 switch all of them on and of when necessary. Fixes the bug when
6837 m4sugar macros (e.g., m4_define) were expanded after the first
6838 automatic update (e.g., after AC_PREREQ or AC_INIT).
6840 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

6862 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
6864 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
6865 aclocal cannot be given on the command line.
6867 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
6869 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
6870 Give an example for AS_DIRNAME instead of referring to Posix..
6871 (File System Conventions): Put discussion of // versus / here, and
6872 modernize it a bit.
6873 (Limitations of Usual Tools): Add basename. Remove verbiage
6874 after dirname, since it got moved to the above sections.
6875 All this was inspired by a patch proposed earlier by Eric Blake.
6877 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6883 `$0', $as_me.
6885 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6887 * bin/autoscan.in: The value of find_configure_ac should be
6888 checked for existence, so we don't barf over a nonexisting
6889 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
6891 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6893 * bin/autoupdate.in: Fix some typos.
6895 2006-03-21 Stepan Kasal <kasal@ucw.cz>
6897 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
6899 * lib/autoscan/autoscan.list: Refreshed.

7412 2005-12-31 Stepan Kasal <kasal@ucw.cz>
7414 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
7415 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
7417 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>

7450 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7452 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
7453 CONFIG_SHELL in the environment of the configure rerun.
7454 * doc/autoconf.texi (Here-Documents, config.status Invocation):
7455 Suggest passing CONFIG_SHELL absolute, and in the environment
7456 rather than as option.

7472 ac_clean_files and LIBOBJS.
7474 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7476 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
7477 Factor functionality to..
7478 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7479 `AC_SUBST($1)' in the public version.
7480 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7481 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
7482 ac_pt_* variables.

7496 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7498 2005-10-25 Stepan Kasal <kasal@ucw.cz>
7500 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
7501 conftst2.$ac_objext.
7502 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7504 2005-10-24 Stepan Kasal <kasal@ucw.cz>
7506 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7507 conftest.o, to see whether the compiler really obeys; rm the object
7508 file before and after the test and register it with ac_clean_files.
7509 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7511 2005-10-21 Stepan Kasal <kasal@ucw.cz>
7513 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
7514 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
7515 code so that the most common case requires less forks.
7517 2005-10-20 Stepan Kasal <kasal@ucw.cz>
7519 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is

7527 the latter'', in two places.
7529 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7531 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7532 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7533 the inner workings of AC_LANG_FUNC_LINK_TRY.
7534 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7535 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7536 by the function rather than ignoring it.
7537 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7538 comparing its address. Intel's interprocedural optimization was
7539 outsmarting the old heuristic. Problem reported by
7540 Mikulas Patocka.
7542 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7544 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

7551 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7553 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7554 before removing it (chmod -R u+rwx); there are three instances of this.
7556 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7557 Stepan Kasal <kasal@ucw.cz>
7559 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7560 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7561 make its content writable before removing it. Remove an errorneous
7562 comment from the end, where the logs of the failed tests are copied
7563 to the main log file.
7565 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7567 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7568 in case the computer is too quick. Double quote the configure.ac
7569 snippets.
7571 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7572 problems if the testsuite were running too fast.
7574 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7576 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7577 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7578 (which belong to Xt, not X itself). See Debian bug 327655.
7579 * NEWS: Mention this.
7581 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7583 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7585 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7587 * config/move-if-change: Don't output "$2 is unchanged";
7588 suggested by Ben Elliston. Handle weird characters correctly.
7590 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7592 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7593 calls, so that the final expansion of this macro is shorter.
7594 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7595 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7596 the cleanup there. Use AS_VAR_* macros, to be more general.
7597 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7599 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7601 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7603 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7605 * doc/autoconf.texi (Configuration Headers): Add an index entry
7606 for AH_HEADER.
7608 2005-08-26 Pavel Roskin <proski@gnu.org>
7610 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7611 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7612 running xmkmf.
7614 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7616 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7617 The previous patch didn't work, so try a better one.
7619 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7621 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7622 in the example. Reported by Bruno Haible.
7623 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7624 "if $undefined_var;" succeeds with my shell.
7626 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7627 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7628 but change the m4_divert_text to m4_divert_once.
7630 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7632 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7633 Work around bug in Solaris /usr/xpg4/bin/awk.
7634 The bug is present in at least Solaris 8 through 10.
7636 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7638 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7639 some evil values and relying on the fact that $* concatenates the
7640 parameters by the first character from IFS.
7642 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7643 Stepan Kasal <kasal@ucw.cz>
7645 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7646 first header appears, define AH_HEADER.
7647 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7648 Update limitations about when to call AC_CONFIG_HEADERS.
7649 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7650 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7651 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7652 ``Configuration Actions''; fix their index entries.
7654 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7655 options correctly. Process N-M as M-N if M is smaller than N.
7656 Process ranges correctly so that N-N will run only N.
7657 Sort and uniquify the tests that will be run. If there is more
7658 than one test, reinsert the banners for the tests.
7659 * tests/autotest.at (Keywords): Unmark XFAIL.
7661 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7663 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7664 before passing the macro name to AH_TEMPLATE.
7666 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7667 now opens log after option processing; in particular, --version
7668 and --help do not touch config.log.
7670 * Makefile.maint: Revert the change from 2005-08-12.
7672 2005-08-22 Stepan Kasal <kasal@ucw.cz>

7680 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7681 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7682 Language cleanup.
7684 * doc/autoconf.texi (Defining Symbols, Changed Results):
7685 Prepend to LIBS, not append, in examples.
7687 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7689 When building in place, set srcdir="."; suggested by Tim Van Holder.
7691 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7692 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7693 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7694 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7695 does not mean "no --srcdir option".
7697 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7699 * tests/autoscan.at (autoscan): New file.
7700 * tests/suite.at: Use it.
7701 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7702 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7704 * tests/autotest.at (Keywords): Test keywords combinations.
7706 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7708 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7709 add "2>&1"; gzip 1.2.4 prints help on stderr.
7711 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7713 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7714 was pushdef'ed twice while popped only once. Push it only once.
7715 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7717 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7719 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7720 prefixed by mere "===", not "configure: === ".

7724 * Makefile.maint: Update from Bison.
7726 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7727 "<tab>" in comment, so that the point is understandable.
7729 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7731 Rewrite substantial part of lib/autoconf/status.m4.
7732 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7733 and CONFIG_COMMANDS are not processed in four separate loops.
7734 Instead, there is one main loop. This alows that the common code
7735 is expanded only once, thus config.status (and configure) is smaller.
7737 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7738 the AC_LIST_FILES and cousins macros are no longer used.
7740 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7741 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7742 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7743 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7744 contain the initialization, nor the for loop, nor the associated
7745 commands; all these go to ...
7746 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7747 _AC_OUTPUT_CONFIG_STATUS.
7748 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7749 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7750 (_AC_OUTPUT_FILE): The creation of the sed script ...
7751 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7752 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7753 _AC_OUTPUT_MAIN_LOOP.
7754 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7755 _AC_CONFIG_COMMANDS): Use ...
7756 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7757 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7758 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7759 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7760 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7761 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7762 ... new macros.
7763 (_AC_CONFIG_UNIQUE): Update.
7764 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7765 Replaced by this ...
7766 (_AC_LIST_TAGS): ... new common macro.
7767 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7768 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7769 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7770 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7771 this didn't belong to the `config commands' section.
7772 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7773 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7774 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7775 to the `config commands' section either.
7776 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7777 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7779 ... and many changes to the comments nearby.
7781 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7782 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7783 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7784 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7785 (#define header templates): The comment at the top of the generated
7786 header now includes the name(s) of the source file(s).
7788 Several unrelated small changes:
7790 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7791 parameter to AC_DIAGNOSE.
7792 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7793 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7794 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7795 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7796 with AU::AC_OUTPUT.
7797 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7798 in AC_OUTPUT doesn't double-quote it either.
7799 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7800 parameters.
7802 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7804 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7805 versions of Portland Group compiler produce single- and double-quoted
7806 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7807 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7809 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7811 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7812 This is a corrected version of yesterday's patch.
7814 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7816 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7817 path, too; insert a "===" to emphasize the line.
7819 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7820 ac_cv_build_alias to ac_build_alias.
7821 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7823 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7824 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7825 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7826 (AC_ARG_VAR): ... here.
7827 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7828 target_alias.
7830 Keep a list of all precious variables and process them with one simple
7831 for loop, instead of expanding all commands, or, OTOH, complicated
7832 processing of output of "set".
7833 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7834 variable names in new macro...
7835 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7836 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7837 a loop to assign all ac_env_* and ac_cv_env_* variables.
7838 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7839 to INIT_PREPARE.
7840 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7841 its value to shell variable ac_precious_vars and call
7842 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7843 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7844 _AC_ARG_VAR_VALIDATE.
7846 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7847 and the AC_SUBSTs ...
7848 (AC_INIT): ... here.
7850 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
7851 the ac_subst_files section in config.log.
7853 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
7855 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

7865 They are generated by the Tru64 v5.1B shell.
7867 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7869 Fix my changes from 2005-07-01; reported by Noah Misch.
7870 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7871 description, the macro now accepts only a single tag.

7879 is not set, use at_top_builddir, for compatibility with older
7880 versions of autoconf.
7882 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7884 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7885 Problem reported by Patrick Welche.
7887 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7889 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7890 sed substitution command, so that we allow | in program prefixes
7891 and program suffixes. (& is a problem anyway; we're not fixing
7892 that here.)

7894 configure_input, top_builddir, srcdir, etc.
7895 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7896 PATH_SEPARATOR in AUTOTEST_PATH.
7898 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7900 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

7906 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

7924 about #include <config.h>.
7925 (Generic Functions): Mention the Gnulib project.
7926 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
7928 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7929 document to output the default config_* lists to config.status.
7930 Don't recognize option --file, if the functionality is not there.
7931 Likewise for --header; moreover, recognize --he and --h as shortcuts
7932 for --help in that case.
7934 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7935 matches the order of execution. No code changed.

7957 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7958 (AC_SUBST): Call it.
7959 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7960 the directory specific variables; but don't call it for configure_input.
7962 2005-06-28 Derek Price <derek@ximbiot.com>
7964 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7965 addition.
7967 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7969 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7970 directory have inherent problems with special characters like spaces,
7971 due to limitations in Make syntax. Problem reported by Alexandre
7972 Duret-Lutz.
7973 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
7974 Also, fix Tru64 porting problem with shell patterns,

7986 from Justace Clutter.
7987 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7988 variable into diagnostic. Make the diagnostic an error, not a warning,
7989 because we really don't support spaces and suchlike in dir names.
7990 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7991 Don't worry about backslashes in srcdir; it can't happen now.
7992 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
7993 Simplify ac_optarg handling.
7994 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8004 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8005 that '\|' is not allowed in BREs; recommend using newline separated
8006 list of patterns instead of multiple -e options.
8008 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8010 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8016 2005-06-21 Stepan Kasal <kasal@ucw.cz>
8018 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8019 b, t, r, w commands require single space, while : cannot have any.
8020 (Special Shell Variables): Fix sed code this in the example.
8021 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8022 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8024 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
8025 expand to the empty list. Don't use two pairs of m4_changequote,
8026 it's not necessary.
8028 2005-06-20 Derek Price <derek@ximbiot.com>
8030 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8032 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8034 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8035 * doc/autoconf.texi:
8036 Don't mention Solaris versions so much, if a
8037 problem is common to all extant versions of Solaris. Say "SunOS
8038 4" instead of "SunOS" for SunOS 4.
8039 (awk): Mention more of the limitations of traditional Awk.
8040 (cat): Don't talk about cat -v.
8042 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

8047 to be compatible with glibc strverscmp.
8048 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
8050 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8051 on Mac OS X 10.4 reported by Peter O'Gorman in:
8052 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
8053 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8054 Use shell builtins rather than 'expr', to work around expr bug.
8056 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8058 * doc/autoconf.texi: "filesystem" -> "file system".
8059 "behaviour" -> "behavior".
8060 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8061 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8062 as per POSIX.
8063 * lib/m4sugar/m4sh.m4: Likewise.
8064 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8065 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8067 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8068 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8069 to update the man page. That way, we don't have to check in new
8070 man pages every month.
8072 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8073 quotes and backslashes. Patch from Derek Price.

8078 AS_TR_SH.
8080 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8082 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8083 -u, since it outputs chatter if the input files are the same.
8084 Problem reported by Ralf Menzel.
8086 2005-06-08 Derek Price <derek@ximbiot.com>
8088 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8089 renaming them since they are about to be redefined anyhow.
8091 2005-06-08 Derek Price <derek@ximbiot.com>
8093 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8094 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8095 Move m4_undefine to alphabetical order.
8097 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8099 * README: Recommend GNU M4 1.4.3 or later.
8100 * doc/autoconf.texi (Introduction): Likewise.
8101 Reword to avoid some formatting glitches.
8102 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8103 Clarify explanation of HP compiler bug.
8104 Redo example output tp match current CVS snapshot.
8105 Use @example.org in email addresses when the examples
8106 might get inadvertently cut-and-pasted into user code.
8107 Remove example of autom4te usage that doesn't seem to work now.
8108 Use modern AC_INIT (except when the example is meant to be
8109 shown with Autoconf 2.13).
8110 Update ksh info for Solaris 9 and later.
8111 KB -> kB.
8112 Modernize description of Automake versions a bit.
8113 Don't claim a future version of Autoconf is near.
8114 * doc/install.texi: Reword to avoid some formatting glitches.
8116 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8118 * doc/autoconf.texi: Add [] to examples, so that the manual
8119 follows its own advice about quoting better.
8120 Reword to avoid some formatting glitches.
8121 * doc/installt.exi: Reword to avoid some formatting glitches.
8123 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8124 Tru64 ksh pattern matching bug. Reported against Libtool by
8125 Albert Chin <libtool@mlists.thewrittenword.com> and
8126 Nicolas Joly <njoly@pasteur.fr>.
8128 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8130 m4_cdr of one-member list was [[]] (one-member list containing an
8131 empty string) instead of [] (an empty list. Callers were skewed to
8132 match this misbehaviour. As a consequence of this:
8133 - m4_foreach([x], [], [foo]) expanded to `foo', while
8134 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8135 This bug has been fixed:
8137 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8138 expand to an empty string; print error msg if called without
8139 an argument list.
8140 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8141 misbehaviour; handle [] and [[]] correctly.
8143 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8145 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

8147 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8149 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8151 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8152 swallow records with more than 99 fields.
8153 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8154 parse the long line.
8156 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8158 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8159 swallow literals longer than 399. Reported by Ralf Wildenhues.
8160 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8161 to workaround this limitation.
8163 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8165 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8166 to gfortran, and make these the first two compiler names
8167 checked (following the general autoconf preference for gcc).
8169 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8171 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8172 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8173 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8175 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8177 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8178 expression of unbounded size when processing the --list
8179 option. This runs afoul of a limit of 399 bytes per regular
8180 expression on AIX. Problem reported by Ralf Wildenhues.
8182 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

8185 * doc/autoconf.texi (Particular Headers): Reword example
8186 for multiline stdbool replacement.
8187 (Setting Output Variables): Reword text a bit. Don't
8188 give all the details about |#_!!_#|.
8189 Reword description of line replacement.
8191 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8193 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8194 now contain newlines, and substituted files must be referenced on
8195 a line alone; the sed scripts to substitute them are now very
8196 different.
8197 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8198 commands can be put in a sed script portably.
8199 * doc/autoconf.texi (Setting Output Variables): Document above
8200 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8201 use of multiline substitution.

8211 * tests/local.at: Don't attempt to check for negated character
8212 classes in shell scripts. The test was too brittle.
8214 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8216 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8217 * doc/autoconf.texi (Limitations of Builtins): Document this
8218 limitation.
8220 2005-05-24 Stepan Kasal <kasal@ucw.cz>

8230 messages when ac_unique_file is not found.
8231 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8232 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8233 commands, for consistency with AC_MSG_ERROR and such.
8235 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8237 * bin/Makefile.am: Merge the two rules for creating scripts.

8247 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8248 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8249 (ac_top_builddir): ... this ...
8250 (ac_top_build_prefix): ... to this; the old name is also kept, for
8251 backward compatibility.
8252 (ac_top_builddir_sub): New variable, without the trailing slash,
8253 always nonempty.
8254 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8255 * doc/autoconf.texi (Configuration Actions): Rename
8256 ac_top_builddir to ac_top_build_prefix.
8257 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

8264 of confdefs.h .
8266 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8268 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8269 argument to m4_foreach. I guess it was necessary in the past,
8270 but I think it's a no-op now.
8272 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8274 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8275 ``cat <<_ACEOF'' commands to one.
8276 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8277 * lib/autoconf/status.m4: On various places, use expr instead of
8278 ``echo|sed.''
8279 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8280 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8281 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8282 a range.
8283 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8284 the wrong patterns between ``case'' and ``esac.'' The previous
8285 code had false positives.
8287 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8289 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8290 as on 2005-05-02.
8291 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8292 Mention LIBOBJDIR.

8332 2005-05-13 Stepan Kasal <kasal@ucw.cz>
8334 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
8335 check.
8336 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
8337 enough arguments, similarly as in m4_bpatsubsts.
8339 2005-05-12 Stepan Kasal <kasal@ucw.cz>
8341 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

8346 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
8347 for absolute directory names in one loop.
8348 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
8349 abbreviations of --version and --debug.
8351 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
8353 * doc/autoconf.texi (Autoconf Language): Be more precise about
8354 quoting rules. Problems noted by Stepan Kasal.
8355 Also, throughout this document, be more careful about white space.
8356 "blank", "white space", and "space" all have different meanings
8357 and we should be careful to say what we mean.
8359 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8361 Fix C++ related problems reported by Werner Lemberg.
8362 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
8363 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
8364 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
8365 avoid problems with C++ and throw.
8366 * tests/compile.at: .cpp, not .cc.
8368 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8370 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8372 * doc/autoconf.texi (Generic Functions): Typos.
8374 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8376 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8377 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8378 set by latest automake.
8380 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8382 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8383 outputs 0 on GNU/Linux these days.
8385 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
8387 * doc/autoconf.texi (Autoconf Language): Add more description
8388 about quoting heuristics.
8389 (Limitations of Builtins): Describe "set -" problems.
8391 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8393 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8394 not newline.
8396 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8397 by AC_DEFINE; it was a mistake.
8398 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8400 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8402 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8404 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8406 * doc/autoconf.texi (External Software): Quadrigraphs are not
8407 processed correctly in AS_HELP_STRING; avoid this in the examples.
8408 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8409 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8410 comment and reduce m4_default([foo], []) to [foo].
8411 (m4_strip): Update the explanation.
8413 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8415 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8416 Remove core.conftest.* too; it's generated by Tru64 5.1.
8417 Problem reported by Jennis Pruett.
8418 * lib/autoconf/functions.m4
8419 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8420 Don't bother to remove core files; AC_RUN_IFELSE should do that
8421 for you.
8423 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8425 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
8427 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

8435 the comment.
8437 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
8439 * doc/autoconf.texi (External Software, Package Options): Add
8440 examples showing how to implement --with-* and --enable-* options.
8442 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8444 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8445 as well as configure.in. Problem reported by Gregorio Guidi.
8447 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8449 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8450 pattern for alloca snippet.

8460 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8462 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8463 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8465 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8467 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8468 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8469 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8470 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8471 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8473 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8475 * NEWS: The configure command now warns you if you attempt to use
8476 a directory whose name contains a special character like space,
8477 newline, or "\".
8478 * doc/autoconf.texi (Installation Directory Variables): Allow
8479 "," in file names. Do not use \@; it's not a portable regexp.
8480 * bin/Makefile.am (edit): Likewise.
8481 * lib/Makefile.am (edit): Likewise.
8482 * tests/Makefile.am (edit): Likewise.
8483 * tests/semantics.at: Likewise.
8484 * tests/torture.at: Likewise.
8485 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8486 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8487 * doc/autoconf.texi (File System Conventions): Warn about
8488 unportable file names.
8489 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8490 (AC_INIT): Use it.
8491 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8492 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8493 ac_pwd, and quote srcdir.
8494 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8496 * doc/autoconf.texi: Fix some systematic formatting problems.
8497 ".)" needs a following @: if not at the end of a sentence, and
8498 similarly for "!)". "etc." should be preceded by a comma.
8499 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8501 2005-03-22 Bruno Haible <bruno@clisp.org>
8503 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8504 argument is often called 'build-aux'.
8506 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8508 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8509 macro AC_TRY_LINK is obsolete.
8510 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8511 `AC_CONFIG_FILES'.
8513 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8515 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8516 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8517 from a Common Lisp's `cl'.
8518 (AC_PROG_CXX): Behave according to the documentation: don't
8519 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8520 make the variable CCC precious; use `cl.exe', not `cl'.
8522 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8523 Alexandre Duret-Lutz <adl@gnu.org>
8525 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8526 /dev/null, as "configure" shouldn't read stdin, and this insulates
8527 us from problems (e.g., when testing for "cl"). Also, do this
8528 redirection before invoking "hostname" or "uname", and keep the
8529 original input stream available via...
8530 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8531 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8532 bother with "</dev/null" since it's now done at the top of
8533 'configure'.
8534 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8535 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8536 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8537 * doc/autoconf.texi (File Descriptor Macros): New section.
8538 (Printing Messages): Mention it.
8539 * tests/base.at (Input/Output): New test.
8541 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8543 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8544 newline if neither \c nor -n work, as that would output two
8545 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8547 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8549 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8550 This causes that any required macros inside will get before the if.
8551 * doc/autoconf.texi (autom4te.cache): A typo.
8553 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8555 Undo previous change, except keep the change to
8556 lib/autoconf/programs.m4 that replaced grep with shell
8557 pattern-matching. This is because net-snmp configure reads stdin.
8558 Reported by Noah Misch.
8560 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8562 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8563 from /dev/null, as "configure" shouldn't read stdin, and this
8564 insulates us from problems (e.g., when testing for "cl").
8565 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8566 before invoking "hostname" or "uname".
8567 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8568 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8569 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8570 "</dev/null" since it's now done at the top of 'configure'.
8571 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8572 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8573 Also, replace grep with shell pattern-matching, to save a process.
8575 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8577 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8578 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8579 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8580 compiler.
8582 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8584 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8585 grep -q isn't portable. Improve grep -s explanation.
8586 Problem reported by Dan Manthey.
8588 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8590 * doc/autoconf.texi (Special Shell Variables): Clarify
8591 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8593 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8595 * doc/autoconf.texi: Use @acronym for DJGPP.
8596 Fix some @code's that should have been @env's, and vice versa.
8597 Sort environment variable names.
8598 Mention that shells no longer inherit IFS.
8599 Don't recommend PATH_SEPARATOR=';' so strongly.
8600 Mention that $RANDOM might expand to the empty string.
8601 "symlink" and "soft link" -> "symbolic link".
8602 Improve mktemp description (reported by Bruno Haible).
8604 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8606 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8607 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8608 Likewise.
8609 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8610 Likewise.
8612 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8614 * NEWS: Mention AT_COPYRIGHT.
8616 * tests/local.at (AT_CMP): Use diff directly on input files rather
8617 than copying them.
8619 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8620 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8622 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8623 and Paul Eggert <eggert@cs.ucla.edu>
8625 * tests/autotest.at (Empty test suite): New test.
8626 * tests/torture.at (Substitute and define special characters)
8627 (Substitute a 2000-byte string, Define to a 2000-byte string)
8628 (Substitute a newline, Define a newline): New tests.
8630 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8632 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8633 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8634 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8635 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8636 (Standard regular expressions): New test.
8637 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8638 excess test name quoting.
8639 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8640 CPPFLAGS to `configure' instead of setting it in `configure'.
8642 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8643 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8644 on some platforms.
8646 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8647 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8649 * tests/local.at (AT_CMP): New macro.
8650 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8651 (AC_SAVE_STATE): Move environment grep...
8652 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8653 (AT_CONFIG_CMP): New macro.
8654 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8655 * tests/c.at (Extensions): Do not exit early.
8656 * tests/atlocal.in: Inherit $GREP.
8658 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8659 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8661 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8662 (AC_COPYRIGHT): Factor header comment portion out and move into...
8663 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8664 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8665 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8666 --version output.
8667 * tests/local.at: Add Autoconf test suite copyright notice.
8668 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8670 2005-02-04 Bruno Haible <bruno@clisp.org>
8671 and Paul Eggert <eggert@cs.ucla.edu>
8673 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
8675 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8677 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8678 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8680 Try not to generated lines of unlimited length, as POSIX places a
8681 2047-byte limit on line length of portable text files.
8682 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8683 Use newline as a separator, not space.
8684 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8685 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8686 space.
8688 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8690 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8691 as_func_*. Add test to check whether positional parameters
8692 are restored after function return.
8694 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8696 * doc/autoconf.texi (Special Shell Variables): Mention _,
8697 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8698 if they contain a lower-case letter. The DUALCASE problem was
8699 reported by Ralf Wildenhues.
8701 * bin/autoconf.as: Don't exit with status 0 after write failure
8702 with --help or --version.
8703 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
8704 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
8706 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8708 * doc/autoconf.texi (Limitations of Usual Tools):
8709 Unicos 9 sed limitations.
8710 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
8711 to get the option-enhanced interface on older Crays. Try ftn for
8712 Fortran 95 (newer Crays).
8714 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
8716 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8717 care to echo the commands, so the user knows what's going on.
8718 Modified from a suggestion by Stepan Kasal.
8720 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
8721 with a cross reference. Derived from a suggestion by Bruce Korb.
8723 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
8725 * doc/autoconf.texi (config.status Invocation): Warn about
8726 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
8727 * doc/install.texi (Defining Variables): Likewise.
8728 Based on a proposed patch by Ralf Wildenhues.
8730 * man/Makefile.am (.x.1): Make sure the required generated files
8731 are up to date. Problem and original solution proposed by Stepan Kasal.
8732 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
8733 implicit-man-prerequisites): New rules, used by the above.
8735 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
8736 * config/config.guess, config/config.sub, config/install-sh: Likewise.
8737 * config/missing, config/texinfo.tex: Likewise.
8739 2005-01-29 Stepan Kasal <kasal@ucw.cz>
8741 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8742 Update the long comment explaining it.
8744 m4_require no longer writes an ``is required by'' line to the
8745 execution stack. It contains only one bit of non-redundant
8746 information: that the macro was required, not called. And even
8747 this bit is useless in most situations: have you ever met a macro
8748 which both calls and requires the same macro?
8750 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...

9170 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9171 "char c = '\200';" rather than "char c = 0x80;" as the

9212 2004-11-23 Stepan Kasal <kasal@ucw.cz>
9214 * doc/autoconf.texi (Pretty Help Strings): Fix quoting issues
9215 with the examples; fix the bug in MY_ARG_WITH example reported
9216 by Alexandre Duret-Lutz.
9217 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_ENABLE): Enable
9218 expansion of $1 in the comment emitted to configure.

9228 * doc/autoconf.texi (Autoconf Language): Explain that
9229 ``descriptions'' may not be double quotes.
9230 (Quotation Rule Of Thumb): Likewise.
9231 (Pretty Help Strings): Likewise; remove the wrong comment;
9232 simplify the examples and improve their quoting.
9234 2004-11-13 Stepan Kasal <kasal@ucw.cz>
9236 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9237 the $1_found variable, don't test whether the file is executable;
9238 Both things are checked ...
9239 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
9240 the former ``test -f''.
9241 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
9243 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
9245 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
9246 use cp -R instead.
9248 2004-11-10 Derek R. Price <derek@ximbiot.com>
9250 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
9251 limitations. Reorder paragraphs for clarity.
9253 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
9255 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9256 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9257 variants", "Unix", and some related minor wording fixups.
9259 (Shellology, Special Shell Variables): Document that the Zsh
9260 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9261 to Alexandre Duret-Lutz for this info.

9272 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
9274 * doc/autoconf.texi (auindex): New macro.
9275 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9276 Problem reported by Stepan Kasal.
9278 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
9280 Fix problems reported by Andreas Buening in:
9281 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
9282 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9283 in test makefile.
9284 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9285 readable; it's not true in OS/2-emx.
9287 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9289 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9290 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9291 (trivial change). Problem and patch reported by Andrew Church in:
9292 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9294 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
9296 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
9297 three args in examples. Problem reported by Frederik Fouvry in:
9298 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
9299 Also, fix some minor spacing and punctuation bugs.
9301 2004-09-02 Akim Demaille <akim@epita.fr>
9303 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
9304 "case" to restore ordering.
9305 Reported by Stepan Kasal.
9307 2004-08-26 Akim Demaille <akim@epita.fr>
9309 * doc/autoconf.texi: Minor typos and stylos.

9315 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
9317 Version 2.59b.
9319 * README: Add advice about m4 1.4.2.
9321 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9322 texinfo.tex for now (done by hand now).
9323 * Makefile.maint (wget_files, cvs_files):
9324 Remove ansi2knr.c; nobody uses it.
9325 (ansi2knr.c-url_prefix): Remove.
9326 (cvs-update): Fix test for failure. I don't know why it ever
9327 worked...
9329 * doc/autoconf.texi: Update URLs, some of which went stale.
9330 Use @uref rather than @href.
9332 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9333 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9335 * config/config.guess, config/config.sub, config/elisp-comp,
9336 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9337 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9339 * NEWS, TODO, configure.ac, bin/autoscan.in,
9340 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
9341 doc/install.texi, lib/Autom4te/Configure_ac.pm,

9345 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9346 tests/tools.at, tests/torture.at:
9347 Use "file name" rather than "filename" or "path",
9348 to be consistent with the terminology of the GNU coding standards.
9350 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9352 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9353 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9354 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9355 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9357 More fixes to support spaces in the name of the build directory.
9358 This isn't a complete fix but it's an improvement.
9360 * bin/autoconf.as (autom4te_options): New var.
9361 Use it instead of appending to AUTOM4TE, so that we can allow
9362 spaces in the build directory's absolute name.
9363 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9364 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9365 AT_CHECK_NOESCAPE): Likewise.
9366 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9367 main program): Likewise.
9369 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9371 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
9372 From Ralf Corsepius in:
9373 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
9375 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
9377 * doc/autoconf.texi (Function Portability): Document isinf and
9378 and isnan. From a suggestion by Kevin Ryde.
9380 * lib/Autom4te/General.pm (END): Return correct exit status even
9381 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9383 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9385 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9386 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9387 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9389 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9391 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9392 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9393 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9394 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9395 * lib/autom4te.in (Automake-preselections): Preselect
9396 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9398 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9400 * lib/autom4te.in (Automake-preselections): Preselect
9401 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9402 trace them.
9404 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9406 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9407 Tru64.
9408 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9409 Document problem with "`""`" in pdksh POSIX mode.
9411 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9413 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9414 with pdksh, too. Problem reported by Patrick Welche via
9415 Gary V. Vaughan.
9416 * doc/autoconf.texi (Shellology): Note that set -o posix is
9417 useful for pkdsh, too.
9419 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9421 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9422 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9423 Don't fail if ENV or BASH_ENV is readonly.
9424 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9425 etc. are read only. Problem reported by Ludovic Courtes.
9427 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9429 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9430 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9431 (trivial change)
9433 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9435 * doc/autoconf.texi (File System Conventions): Warn about
9436 names like "aux". Problem reported by Eric Blake.
9438 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9439 by zero instead of array size, so that we can use any arithmetic
9440 constant expression (instead of requiring an integer constant
9441 expression). This allows us to test expressions like DBL_MAX <
9442 LDBL_MAX, which didn't conform to the C standard using the old
9443 method.
9444 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9445 now that we can do floating-point tests at compile time.
9447 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9449 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9450 and LDBL_EPSILON, as the resulting expression isn't an
9451 integer constant expression and violates the C standard.
9452 Problem reported by Nelson H. F. Beebe. Also, check
9453 for "L" suffix, and check that long double doesn't have
9454 worse range or precision than double, that mixed-mode
9455 arithmetic doesn't generate a diagnostic, that double
9456 constants fit in long double.
9458 2004-06-03 Kevin Ryde <user42@zip.com.au>
9460 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9461 malloc(0) and realloc(NULL,size).
9463 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9464 Bob Proulx.
9466 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9468 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9469 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9470 by Jim Meyering.
9472 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9474 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9475 can be rewritten using if-then-else. Suggested by Bruno Haible.
9477 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9479 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9480 Problem reported by Stepan Kasal.
9482 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9484 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9485 change). Patch reported by Ralf Wildenhues in
9486 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9488 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9489 function F exists if the compiler and linker let you compile an
9490 expression like (F != 0). Recent versions of GCC optimize away
9491 the reference to F in that case, since every function address must
9492 be nonzero, so the link succeeds even if F does not exist.
9493 Problem reported by Manu in
9494 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9496 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9497 "Unix". Many uses changed.
9498 (Limitations of Builtins): Explain better why the ! command isn't
9499 portable.
9501 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9503 * lib/autom4te.in (Automake-preselections): Preselect
9504 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9506 2004-05-19 Kevin Ryde <user42@zip.com.au>
9508 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9509 referencing AC_FUNC_STRERROR_R.
9511 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9512 note pessimistic assumption when cross compiling.
9514 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9516 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9517 (until 2004) invoked subcommands with sh -e, contra POSIX.
9518 Reported by Kevin Ryde.
9520 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9522 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9523 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9524 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9525 `test -f " /usr/bin/grep"', which _always_ failed.
9526 (AC_PROG_SED): Ditto bogus PATH fix.
9527 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9528 requires that grep correctly supports _multiple_ `-e' options, rather
9529 than stating only that grep should accept `-e'.
9531 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9533 Port to C99, which requires that 'exit' be declared.
9535 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9536 to ensure that stdlib.h is included.
9537 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9538 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9539 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9540 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9541 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9542 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9543 when using 'exit' in a test; C99 requires that 'exit' be declared.
9545 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9547 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9548 now prefers 'grep' implementations that accept -e.
9549 (Limitations of Usual Tools): Describe problems of traditional
9550 egrep and fgrep with long input lines, and of traditional grep
9551 with -e.
9552 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9553 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9554 All callers changed. Append /usr/xpg4/bin to the PATH, for
9555 Solaris.
9556 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9557 the user with complaints about multiple -e options.
9558 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9559 Define it with AC_PROG_GREP.
9560 * configure.ac (AC_PROG_GREP): Add.
9561 * lib/freeze.mk (GREP): New macro.
9563 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9565 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9566 a possible candidate only after all others fail, rather than
9567 consulting it first. This improves backward compatibility by
9568 better reflecting the way shell selection occurred in previous
9569 versions of Autoconf, and should help to avoid triggering latent
9570 problems in other packages, such as the one in Automake where zsh
9571 is not handled robustly:
9572 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9573 Although it is not Autoconf's responsibility to work around
9574 problems in Automake, it nevertheless makes sense to avoid
9575 introducing unnecessary incompatibilites.
9577 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9578 Gary V. Vaughan <gary@gnu.org>
9580 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9581 how deeply nested we are when a suitable tool is found, set the
9582 ac_path_TOOL_found flag.
9583 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9584 nested we are in this macro. Break out of all 3 nested loops if
9585 ac_path_TOOL_found is set.
9587 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9589 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9590 of the _AS_PATH_WALK loop too if GNU flavor is found.
9592 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9594 * doc/autoconf.texi (Limitations of Make): Update documentation
9595 for `$<'. New entry `Long lines', based on a report from Simon
9596 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9597 paragraph about DJGPP, based on a mail from Richard Dawe.
9599 2004-04-20 Paul Eggert <eggert@twinsun.com>
9601 * tests/c.at (C keywords): Don't assume that GCC supports
9602 "restrict" and "inline", as sufficiently-old GCC versions do not
9603 (also, GCC configured to be in pedantic C89 mode does not).
9604 Problem reported by Sumit Pandya in:
9605 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9607 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9608 consider -g to work if it generates warnings when plain compiles
9609 don't. Problem reported by Braden McDaniel in:
9610 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9612 * doc/autoconf.texi (Slashes): New section, to document a problem
9613 reported by Jim Meyering in:
9614 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9616 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9617 linker output files before linking, to work around IRIX 6 linker bug.
9618 Problem reported by Rainer Orth in:
9619 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9621 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9623 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9624 best tool so far counter rely on the tool path variable name to
9625 avoid checks for one tool being affected by the results of running
9626 the length check on a previous tool.
9628 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9629 match expression argument, as different greps have different
9630 regular expression flavours.
9631 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9632 literals.
9633 (AC_PROG_EGREP): Pass 'EGREP$'.
9634 (AC_PROG_GREP): Pass 'GREP$'.
9636 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9638 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9639 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9641 2004-03-29 Paul Eggert <eggert@twinsun.com>
9643 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9644 Types, Specific Compiler Characteristics, System Services,
9645 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9646 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9647 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9648 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9649 Likewise.
9650 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9651 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9652 AC_TYPE_OFF_T): Likewise.
9653 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9654 Likewise.
9656 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to

9663 HAVE_STRUCT_TM_TM_ZONE is not defined.
9664 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9665 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9666 for HAVE_TZNAME.

9714 new macros.
9715 * NEWS: Document these changes.
9717 * doc/autoconf.texi: Avoid macros with unbraced arguments,

9723 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9724 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

9742 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9743 from the next generation of Libtool.
9744 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9746 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9748 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9749 is not always thread-safe. Report from Nathanael Nerode.
9751 2004-02-18 Paul Eggert <eggert@twinsun.com>
9753 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9754 problem on QNX reported by Stephen Rasku in
9755 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9757 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9758 $(m4sh_m4f_dependencies); this removes a FIXME.
9759 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9760 (MAINTAINERCLEANFILES): Split into pieces,
9761 one per related section. Add $(srcdir)/wrapper.in.

9766 AC_SUBST provides no portable way to escape literal newlines.
9768 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9769 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9770 Darwin uses -lcrt2.o and there's little point to cataloging all
9771 the system variants. Partial fix reported by Andreas Waechter in:
9772 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9773 for bug reported by Nelson H. F. Beebe in:

9796 Eric Sunshine <sunshine@sunshineco.com>
9797 Paul Eggert <eggert@twinsun.com>
9799 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

9801 parameter. Expand _AS_SHELL_FN_SPY.
9802 (AS_INIT_WITH_SHELL_FN): Removed.
9803 (_AS_SHELL_FN_SPY): New macro.
9804 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9805 macros.
9806 (AS_SHELL_SANITIZE): Remove loop to find better shell
9807 and documentation for the parameter.

9811 (AS_REQUIRE_SHELL_FN): Require shell functions when
9812 it is used.
9813 (_AS_LINENO_WORKS): Put around braces, we do not
9814 trigger the bash bug anymore.
9815 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9816 use AS_INIT_WITH_SHELL_FN.
9817 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9819 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

9825 (AU_DEFUN): Honor the third parameter, create autoupdate
9826 macros with AU_DEFINE.
9827 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9828 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

9847 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9848 2003 (except 1997) to the list of copyright years. This undoes
9849 the 2003-05-22 change, which removed the older years from the list.
9850 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9852 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9853 Albert Chin-A-Young <china@thewrittenword.com>

9859 AC_PROG_GREP.

9863 _AC_PROG_GREP, and AC_PROG_SED.
9864 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9865 longest input length accepted by a command.
9866 (AC_PROG_SED): Use it.

9877 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9878 bin/autoconf.in, config/Makefile.in, config/config.guess,

9892 sources.
9894 2004-01-26 Paul Eggert <eggert@twinsun.com>
9896 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9897 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9898 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9899 not <inttypes.h>. Problem reported by Tim Mooney in
9900 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9901 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9902 Likewise.
9904 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9905 otherwise "make check" fails because it forbids cmp (I guess
9906 because cmp treats files as binary on DOS-like systems).
9908 * tests/mktests.sh: Update copyright date to 2004, since some tests
9909 have changed in 2004.
9911 2004-01-23 Gary V. Vaughan <gary@gnu.org>

9914 non-truncating sed or gsed program in PATH.
9915 * tests/acprograms.at: Add it.
9916 * doc/autoconf.texi (Particular Programs): Document it.
9917 * NEWS: Updated.
9919 2004-01-15 Paul Eggert <eggert@twinsun.com>
9921 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9922 -std1 disables some useful extensions on Tru64. Problem reported
9923 by N. Lichtmaier in
9924 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9926 2004-01-14 Paul Eggert <eggert@twinsun.com>
9928 * doc/autoconf.texi (Programming in M4sh): Document that
9929 AS_MKDIR_P succeeds if the destination is a symbolic link
9930 to an existing directory.
9931 (Limitations of Usual Tools): Note that mkdir -p might not
9932 succeed on symlinks to directories.
9934 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9936 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9937 * bin/autoheader.in: Grammar fix in message.
9938 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9939 Test for dir before calling mkdir -p. (trivial changes)
9941 2004-01-13 Eric Blake <ebb9@byu.net>
9943 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9944 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9946 2004-01-10 Jim Meyering <jim@meyering.net>
9948 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9950 2004-01-09 Paul Eggert <eggert@twinsun.com>
9952 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9953 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9954 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9955 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9956 AC_COMPILE_IFELSE, since we now assume our caller invokes
9957 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9958 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9959 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9960 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9962 2004-01-07 Paul Eggert <eggert@twinsun.com>
9964 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9965 `"'...'"`, as it's confusing (and I suspect it may not work on
9966 some platforms). The code was incorrect anyway, as it assumed
9967 that \$ evaluated to itself in that context. Reported by
9968 Alexandre Duret-Lutz.
9970 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9972 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9973 and _LT_AC_TAGCONFIG.
9975 2004-01-06 Paul Eggert <eggert@twinsun.com>
9977 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9978 example, and add more examples. Reported by Eric Sunshine.
9980 2004-01-05 Paul Eggert <eggert@twinsun.com>
9982 * doc/autoconf.texi (Limitations of Usual Tools):
9983 Remove warning against "rm -fr" introduced yesterday; it
9984 was a false alarm.
9986 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9987 autoscan, autoupdate, ifnames): Don't use chmod -w.
9988 * lib/Makefile.am (autom4te.cfg): Likewise.
9989 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9990 "chmod -w".
9992 2004-01-04 Paul Eggert <eggert@twinsun.com>
9993 Paolo Bonzini <bonzini@gnu.org>
9995 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9996 by doing lineno substitution only on lines containing "$LINENO".
9998 2004-01-04 Paul Eggert <eggert@twinsun.com>
10000 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10001 Use "rm -f" to remove conftest.sed, not plain "rm".
10002 Bug reported by David Relson in
10003 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10005 * Makefile.am (autom4te-update):
10006 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10007 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10008 * doc/autoconf.texi (Guidelines): Likewise.
10009 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

10018 Warn against "rm -fr".
10020 2004-01-03 Paul Eggert <eggert@twinsun.com>
10022 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10023 -c -o might not work. From a suggestion by Kevin Ryde.
10024 (C Compiler, Generating Sources, Limitations
10025 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10026 Don't put '-o' after non-options, as POSIX doesn't allow this.
10027 Mention that cc's name might be gcc or c89 or whatever.
10029 2004-01-04 Kevin Ryde <user42@zip.com.au>
10031 * doc/autoconf.texi: Add various further index entries.
10033 2003-12-29 Paul Eggert <eggert@twinsun.com>
10035 * bin/autoreconf.in (autoreconf_current_directory):
10036 Fix typo: mkdir without umask arg.
10038 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10040 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10041 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10042 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10043 explanation clearer.
10045 2003-12-24 Andreas Schwab <schwab@suse.de>
10047 * doc/autoconf.texi (Default Includes): Fix misspelling of

10053 * configure: Regenerate.
10054 * tests/atlocal.in: Store the result here.
10055 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
10056 tools.at, looking in atlocal's ac_cv_sh_n_works instead
10057 of explicitly testing.
10058 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10059 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10060 * tests/tools.at (Syntax of the shell scripts): Simplify
10061 using AT_CHECK_SHELL_SYNTAX.
10062 (Syntax of the Perl scripts): Remove definition of
10063 AT_CHECK_PERL_SYNTAX.
10065 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10067 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect

10075 Extracted from AS_SHELL_SANITIZE.
10076 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
10077 macros.
10078 (AS_SHELL_SANITIZE): Move reinvocation code from
10079 _AS_LINENO_WORKS, use it to find out if shell
10080 functions work.
10081 (_AS_LINENO_WORKS): Don't find another shell if $LINENO

10097 No longer rely on Gnus to inline the list of signatures: compute

10102 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

10151 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

10171 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

10180 2003-11-05 Kevin Ryde <user42@zip.com.au>

10312 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10314 2003-10-10 Andreas Schwab <schwab@suse.de>
10316 * bin/autoheader.in: Avoid empty first line in --version and
10317 --help output.

10328 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10329 -mGLOB_options_string stuff for Intel ifc, which can cause
10330 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10331 pattern-matching instead of grep.
10333 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>

10343 * NEWS: Updated.

10351 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10353 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10354 cache variable instead of $G77 to decide whether to include -O2,
10355 since $G77 is specific to Fortran 77.

10359 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

10365 arguments so that it can be used with syntax identical to
10366 AC_PROG_F77, and so that we can more easily decide to
10367 remove/deprecate the DIALECT optional argument in the future if it
10368 proves troublesome.
10369 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10370 non-freeform-supporting compilers. Document freeform flags.
10372 2003-10-03 Akim Demaille <akim@epita.fr>
10374 * configure.ac: Look for emacs, not macs.
10375 Reported by Eric Sunshine.
10377 2003-10-03 Akim Demaille <akim@epita.fr>
10379 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10380 * bin/autoreconf.in (autoreconf_current_directory): Create the
10381 AUX_DIR if needed, for sake of automake --add-missing etc.
10382 Suggested by Alexandre Duret-Lutz.
10384 2003-10-03 Akim Demaille <akim@epita.fr>
10386 * configure.ac: Quotation and formatting changes.

10409 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.

10436 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10437 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10439 2003-09-26 Akim Demaille <akim@epita.fr>
10441 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10442 directory for AC_CONFIG_COMMANDS' first argument exists.
10443 This makes valid the invocation of _AC_SRCPATH that follows.
10444 Reported by Eric Sunshine.
10445 * doc/autoconf.texi (Configuration Commands): Adjust.
10447 2003-09-26 Akim Demaille <akim@epita.fr>

10450 Reported by Ralf Corsepius.
10452 2003-09-26 Akim Demaille <akim@epita.fr>
10454 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the

10468 The test suite are sometimes assigning timings incorrectly.
10469 Reported by Henk Krus.
10470 Diagnosed by Nicolas Joly.
10472 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10473 AT_help_all.
10474 Instead of making AT_help a sequence of assignments to grow
10475 $at_help_all, just make AT_help_all be the growing contents of
10476 $at_help_all, and make a single assignment in...
10477 (AT_INIT): here.
10478 (at_times_skip): Flip the meaning and rename as...
10479 (at_times_p): this.
10480 (AT_INIT): When summarizing the test that ran, remove
10481 $at_times_file after use, and check it is present before trying to
10482 use it.

10490 (ifnames): chmod -w.
10491 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10492 executables, not bin/ executables! Otherwise all the magic needed
10493 to find non installed files is turned off. This caused a failure
10494 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10495 as found in its environment (sent by tests/autoreconf): pointing
10496 to bin/autom4te that could not find its files.
10497 * tests/mktests.sh: Force the replacement of generated files, for
10498 the sake of "mv" program that are interactive when overwriting a
10499 -w file.
10500 * config/install-sh: Upgrade from CVS Automake.

10514 any warning.

10548 2003-09-10 Akim Demaille <akim@epita.fr>
10550 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10551 and AC_FC_FREEFORM.

10573 2003-09-05 Paul Eggert <eggert@twinsun.com>
10575 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10576 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10578 2003-09-04 Akim Demaille <akim@epita.fr>
10580 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10581 AC_FUNC_WAIT3.
10583 2003-09-04 Akim Demaille <akim@epita.fr>
10585 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10586 (freeze): When exiting, use $exit_code.
10587 * lib/autoconf/fortran.m4: Comment changes.
10589 2003-09-04 Akim Demaille <akim@epita.fr>
10591 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10593 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10595 Add support for newer Fortran dialects. The F77 interface is
10596 unchanged, and continues to support Fortran 77. New FC macros
10597 correspond to all the old F77 macros, with output variables FC,
10598 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10599 available dialect, but older dialects can be specified. There are
10600 new macros AC_FC_SRCEXT to set the source extension, and
10601 AC_FC_FREEFORM to accept free-form source files.
10603 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10604 New macros.

10608 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),
10609 AC_LANG_PROGRAM(Fortran), AC_LANG_CALL(Fortran),
10610 AC_LANG_PREPROC(Fortran), AC_LANG_COMPILER(Fortran),
10611 _AC_FC_DIALECT_YEAR, _AC_F95_FC, _AC_F90_FC, _AC_F77_FC,

10616 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
10617 AC_FC_SRCEXT, AC_FC_FREEFORM):
10618 New macros.
10619 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
10620 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10621 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10622 Rewrite in terms of the above.
10623 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10624 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
10625 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
10626 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
10628 2003-09-02 Paul Eggert <eggert@twinsun.com>
10630 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10631 Document problems with timestamp resolution that 'make', 'cp -p', and
10632 'touch -r' have.
10634 2003-08-27 Akim Demaille <akim@epita.fr>
10636 * tests/m4sugar.at (cross_warning): Make sure to enable the
10637 output, so that we can track spurious m4sugar output.
10638 * tests/local.at: Require 2.57.
10639 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10640 are defaulted by AT_CHECK anyway.
10641 Use AT_CHECK_AUTOM4TE.
10642 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10643 missing dnl.
10645 2003-08-27 Akim Demaille <akim@epita.fr>
10647 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10648 when -Wobsolete is set.
10649 Set it on by default.
10650 Suggested by Klee Dienes.
10652 2003-08-27 Akim Demaille <akim@epita.fr>

10655 documentation.
10656 From Guido Draheim.
10658 2003-08-26 Akim Demaille <akim@epita.fr>
10660 * doc/autoconf.texi (Output): Make clear that one can run code
10661 after AC_OUTPUT.
10663 2003-08-25 Akim Demaille <akim@epita.fr>
10665 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
10666 CVS Bison.
10668 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>

10671 Automake versions prior to 1.8.
10673 2003-08-25 Akim Demaille <akim@epita.fr>
10675 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.

10694 2003-08-22 Akim Demaille <akim@epita.fr>
10696 Output stack traces in warnings.
10698 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10699 Replace the former...
10700 (m4_warn): Pass the call stack to _m4_warn.
10701 * bin/autom4te.in: Adjust to output the call stack.
10702 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10704 2003-08-22 Akim Demaille <akim@epita.fr>
10706 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

10709 2003-08-21 Akim Demaille <akim@epita.fr>
10711 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10712 (&verbose): Remove.
10713 (&getopt): Adjust the note and verb channels, depending upon
10714 --verbose.
10715 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10716 * bin/autoupdate.in: Adjust.
10717 Use &verb, not &verbose.
10719 2003-08-21 Akim Demaille <akim@epita.fr>
10721 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10722 &parse_WARNINGS.
10723 ($help): Use Autom4te::ChannelDefs::usage.
10724 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10725 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10727 2003-08-21 Akim Demaille <akim@epita.fr>
10729 First stab at preserving warnings between calls to autom4te,
10730 including when the cache is used.
10732 There are still several issues: (i) there are too many runs of m4
10733 (one for include, one for warnings, and some more), (ii) warnings
10734 spreading on several lines are not handled gracefully, (iii) the
10735 code meant to have the call stack display for errors does not work
10736 (its handling should move from m4 to autom4te).
10738 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10739 Use them.
10740 (@preselect): Add m4_warn.
10741 ($exit_status): Remove, use $exit_code.
10742 ($help): Use Autom4te::ChannelDefs::usage.
10743 (&handle_m4): No longer define the m4_warnings.
10744 At each run, extract and report the warnings.
10745 Always cache the result, including if the exit status is on
10746 failure, since if nothing changes, we should result in the same
10747 failure, hence we can use the cache.
10748 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10749 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10750 Remove.
10751 (m4_warn): Redefine as a do-nothing: it is its invocation that
10752 matters, as warnings are now reported via traces.
10753 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10754 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10755 the latter reveals calls to the former.
10757 Adjust the tests.
10759 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10761 2003-08-21 Akim Demaille <akim@epita.fr>
10763 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10764 Use them.
10766 2003-08-21 Akim Demaille <akim@epita.fr>
10768 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10769 forward order.
10770 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10771 (&parse_warnings): Accept a list of warning requests.
10772 (&usage): Return a string, not a side effect.
10773 (cross): New warning category.
10775 2003-08-21 Akim Demaille <akim@epita.fr>
10777 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10778 (&require_configure_ac): Accept an optional directory argument.
10779 ($configure_ac): Remove.
10780 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10781 (&catfile): Remove.
10782 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10783 * bin/autoscan.in: Adjust.
10785 2003-08-20 Akim Demaille <akim@epita.fr>
10787 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10788 Reported by Alexandre Duret-Lutz.
10790 2003-08-20 Akim Demaille <akim@epita.fr>
10792 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10793 * bin/autom4te: Adjust.
10794 In particular, be Autoconf tools are really silent when properly
10795 working, bind the verbosity of the 'note' channel to $verbose.
10796 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10797 (&xsystem, &contents): Remove, since they are exported by...
10798 * lib/Autom4te/FileUtils.pm: this.
10799 More perldoc.
10800 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10801 * lib/Autom4te/FileUtils.pm: here.
10803 2003-08-20 Akim Demaille <akim@epita.fr>
10805 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10806 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10807 from CVS Automake.
10809 2003-08-20 Akim Demaille <akim@epita.fr>
10811 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10812 (autom4te-update): New.
10813 * Makefile.cfg (update): Bind autom4te-update.
10815 2003-08-19 Derek Price <derek@ximbiot.com>
10817 * lib/autotest/general.m4: Comment various HELP_* diversions.

10854 STDOUT & STDERR arguments.
10856 2003-08-14 Derek Price <derek@ximbiot.com>
10858 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10859 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10860 shorter column three. Add DESCRIPTION to log file content.
10862 2003-08-13 Derek Price <derek@ximbiot.com>
10864 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10865 output.

10869 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10870 (AT_CHECK_NOESCAPE): Move core functionality to...
10871 (_AT_CHECK): ...this new macro.
10873 2003-08-07 Derek Price <derek@ximbiot.com>

10876 (AT_CHECK_NOESCAPE): ...to this new macro.
10878 2003-07-31 Paul Eggert <eggert@twinsun.com>
10880 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10881 in Bash 2.01. Problem reported by Brian Gough in
10882 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10884 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>

10892 inside '#ifndef __cplusplus'. Problem reported by
10893 Bob Friesenhahn.
10895 2003-07-06 Bill Clarke <llib@computer.org>
10897 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10898 'long', not 'int', for benefit of Sun's recent C++ compilers
10899 (trivial change). See:
10900 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10901 (This really should be 'intptr_t', not 'long', but that would
10902 take more work.)
10904 2003-06-25 Akim Demaille <akim@epita.fr>
10906 * lib/Makefile.am (autom4te.cfg): Make it read only.
10907 Depend on Makefile since it contains substitutions.
10908 From Paolo Bonzini.

10920 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10921 not all of them. This fixes 1. the fact that when testing
10922 Autoconf there are many many config.log, 2. the incorrect use of
10923 top_srcdir to find config.log.
10924 Don't mix the detailed output of failed test with the summary of
10925 failures. Rather, append detailed log afterwards.
10927 2003-06-23 Akim Demaille <akim@epita.fr>
10929 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10939 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10940 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10941 * tests/atspecific.m4: Rename as...

10950 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10951 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10952 ensuring we add -std1 for full-ANSI.
10954 * doc/autoconf.texi (hdrindex): New macro.
10955 Add index entries for portability of various standard header files.
10957 2003-06-20 Akim Demaille <akim@epita.fr>
10959 * configure.ac: Bump to 2.57b.
10961 2003-06-20 Akim Demaille <akim@epita.fr>

10972 * lib/autotest/general.m4: Use at_times_file only if used.
10973 From Nicolas Joly.
10975 2003-06-20 Akim Demaille <akim@epita.fr>
10977 * config/config.guess, config/config.sub, config/elisp-comp,
10978 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
10979 Update from masters.
10981 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10983 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10984 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10985 (TEST_SCRIPT): New diversion.
10986 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10987 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10988 (AT_INIT): Support for expected failures.
10990 2003-06-02 Akim Demaille <akim@epita.fr>

10993 changes.
10994 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10995 Autoconf nor Automake.
10996 (&contents): New, from Automake.
10997 PODify.
10999 2003-05-28 Paul Eggert <eggert@twinsun.com>
11001 * NEWS, doc/autoconf.texi (Particular Functions),
11002 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11003 is the inverse of localtime.
11005 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
11007 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11008 (handle_exec_errors): New function. Work around $! being
11009 altered by WEXITSTATUS.
11010 (xqx, xsystem): Use handle_exec_errors.
11012 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11014 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11015 Do not call `_exit()', simply modify `$?'.
11016 (xsystem): Reset $! before running system, and check it afterward.
11017 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11018 63 for version mismatches.
11020 2003-05-23 Akim Demaille <akim@epita.fr>
11022 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11023 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11024 the middle of a line).
11025 * lib/m4sugar/m4sugar.m4: Likewise.
11026 Remove useless spaces in comments.
11028 2003-05-23 Akim Demaille <akim@epita.fr>
11030 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11031 exit 63, so that we (or Automake's "missing") can tell the
11032 difference with a plain failure.
11033 * doc/autoconf.texi (Notices): Adjust.
11035 2003-05-23 Akim Demaille <akim@epita.fr>
11037 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11038 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:

11042 Paul Eggert <eggert@twinsun.com>
11044 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11045 Remove `#include <stdlib.h>' from the list; we should never
11046 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11047 resulting namespace pollution would cause other tests to fail.
11048 Configure scripts run with some older versions of g++ and HP's
11049 aCC would fail due to such an #include. Problems reported by
11050 Matthew Mueller in <http://bugs.debian.org/120704> and by
11051 Keith Bostic in
11052 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11053 In the test, use the test declaration before including <stdlib.h>,
11054 as that's closer to how it'll be used.
11056 2003-05-23 Akim Demaille <akim@epita.fr>
11058 * doc/autoconf.texi (Header Portability): ucred.h.
11059 From Ian Redfern.
11061 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11063 Overhaul Autotest's logging: generate separate log files
11064 in testsuite.dir/NNN/testsuite.log, and append them to
11065 testsuite.log instead of re-running the test verbosely.
11067 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11068 file descriptor, write 0 to at_status_file instead of setting
11069 at_status=0, initialize some new variables (at_status_file,
11070 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11071 to rerun the tests, instead append the at_group_log to the
11072 at_suite_log when a test fails.
11073 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11074 with the AS_MESSAGE_LOG_FD redirected to stdout.
11075 (AT_CLEANUP): save the output status in $at_status_file
11076 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11077 its original place.
11078 (AT_CHECK): since tests are run with a redirected stdout,
11079 and used to be re-run in verbose mode, turn some $at_verbose
11080 into echo, and don't redirect the output of testing stdout
11081 and stderr.
11083 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11084 the name of the debugging directory and information about
11085 its contents.
11087 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11089 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

11204 2003-05-06 Akim Demaille <akim@epita.fr>
11206 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11207 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11208 by aclocal.m4 is changed it might require the importing of another
11209 m4 extension file, i.e., aclocal must be run.
11211 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11212 (&parse_args): Use --force with aclocal if required and supported.
11213 (&autoreconf_current_directory): Use &run_aclocal.

11220 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
11221 argument instead of a file name, so that the request file remains
11222 open during the whole autom4te run.
11223 ($icache_file): New.
11224 (&freeze): Lock the $icache_file.
11226 2003-04-29 Derek Price <derek@ximbiot.com>
11228 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11229 seperator with m4_append_uniq(). It doesn't work.
11230 (AT_CLEANUP): Add `;' to end of at_help_all.
11231 (AT_INIT): Allow --keywords to be specified more than once. When
11232 grepping $at_help_all for keywords, use the field and keyword
11233 seperators to ensure a complete keyword match. Alter at_prev handling
11234 to support the new --keywords behavior.
11236 2003-04-27 Karl Berry <karl@freefriends.org>
11238 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11239 align better with others. I also made some of the individual
11240 entries on one line, for brevity and to make it easier for me to
11241 sort my dir-example file in the Texinfo distribution :).

11282 Use them.
11283 * doc/Makefile.am (CLEANFILES): Adjust.
11284 (TEXI2DVI): Make it --batch.
11286 2003-03-31 Derek Price <derek@ximbiot.com>
11288 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
11289 which removed the main loop.
11290 Thanks to Akim Demaille.
11292 2003-03-29 Akim Demaille <akim@epita.fr>
11294 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,

11296 From Ilya Zakharevich.
11298 2003-03-29 Akim Demaille <akim@epita.fr>

11308 header causes problems.
11310 2003-03-28 Akim Demaille <akim@epita.fr>
11312 * tests/torture.at (Configuring subdirectories): Require aclocal
11313 1.4, otherwise the test fails, as it does support configure.ac.
11314 This fixes the "test 40 failed" bug reports.
11316 2003-03-28 Akim Demaille <akim@epita.fr>
11318 * doc/autoconf.texi (C Compiler): `#line' portability.

11346 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
11347 sense. Verbosify the diversion definitions comment.
11349 2003-03-26 Derek Price <derek@ximbiot.com>
11351 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

11373 file name for the m4 program, when it has an "exe" file extension.
11374 DJGPP's error messages include the error code in brackets -
11375 remove the error code during normalization.

11383 * doc/autoconf.texi (Limitations of Make): Remove the section
11384 about `$<' in inference rules, it was a bogus interpretation of
11385 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
11386 Tru64 make in the "target lookup" section.
11387 (Automake): Automake 1.5+ no longer requires special tools to be
11388 present on the developer's host.
11390 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
11392 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

11406 ${ac_make}.
11408 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11409 When constructing paths with IFS=:, quote the path. If we're
11410 constructing a DOS-style absolute path, we don't want to split it
11411 on the colon.

11428 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11429 to fix a mismatch between example and discussion.
11431 2003-02-24 Kevin Ryde <user42@zip.com.au>
11433 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11434 format starting with "-".

11439 is not portable inside Makefile.
11441 2003-02-20 Akim Demaille <akim@epita.fr>
11443 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11444 compiler says yeah, but preproc says nope, compiler is right.
11445 Conversely, prompt the reader to send a bug report to the
11446 maintainers of the package, not of Autoconf.
11448 2003-02-20 Klee Dienes <kdienes@apple.com>
11450 * bin/autoreconf.in (autoreconf_current_directory): Properly
11451 handle an empty aclocal.m4.

11457 From Larry Jones.
11459 2002-12-23 Paul Eggert <eggert@twinsun.com>
11461 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11462 innocuous variant befor including <limits.h> or <assert.h>. This
11463 works around a bug reported by Albert Chin: HP-UX 11i
11464 (and earlier versions) have a <limits.h> that declares
11465 gettimeofday and many other functions.
11467 2002-12-03 Paul Eggert <eggert@twinsun.com>
11469 Version 2.57.
11471 * NEWS, configure.ac: Update version.
11473 * doc/fdl.texi: Upgrade to FDL version 1.2.
11475 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11476 nontrivially in main's body, so that f's external declaration is
11477 not optimized away in AIX. This should fix the bug reported by
11478 Martin Frydl in
11479 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11481 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11482 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11483 defined, to support freestanding compilers. This should fix the
11484 bug reported by Momchil Velkov in
11485 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11487 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11488 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11489 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11490 by Simon Josefsson in

11523 * Makefile.maint: Sync with Bison, i.e.:
11524 (po-check): Scan .l and .y files instead of the
11525 .c and the .h files that they generate. This fixes the bug
11526 reported by Tim Van Holder in:
11527 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11528 Look for N_ as well as for _. Try to avoid matching #define for

11540 From Paul Eggert and Albert Chin-A-Young.
11542 2002-11-14 Kevin Ryde <user42@zip.com.au>
11544 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11545 than assigning in main, to avoid HP cc +O3 optimizing it away.

11549 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q

11551 option to configure on --recheck.
11552 (AC_OUTPUT): Pass -q from configure to config.status.

11558 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11560 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11561 Makefile.in if Makefile.am exists.

11585 2002-11-05 Akim Demaille <akim@epita.fr>
11587 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11588 Remove.
11589 We _have_ to stop using the old compatibility scheme that tried to
11590 avoid useless backslashes because Libtool 1.4.3 contains a
11591 AC_DEFINE([error_t], [int],
11592 [Define to a type to use for \`error_t' if it is not
11593 otherwise available.])
11594 We _have_ to quote the single quote and backslashes with \. The
11595 old compatibility scheme saw that ` was backslashed, and therefore
11596 did not quote the single quote. Hence before this patch, Autoconf
11597 was not compatible with Libtool.
11599 2002-11-04 Paul Eggert <eggert@twinsun.com>
11601 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11639 2002-10-31 Akim Demaille <akim@epita.fr>
11641 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11642 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11643 Make variable, not a shell variable.
11644 Suggested by Bruno Haible.
11646 2002-10-31 Akim Demaille <akim@epita.fr>
11648 * bin/autom4te.in (load_configuration): Reject #args out of any

11669 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11670 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11671 Problem reported by Bruno Haible.
11673 2002-10-29 Akim Demaille <akim@epita.fr>
11675 * doc/autoconf.texi (Header Templates): Put also in words what the

11969 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
11970 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
11971 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
11972 /dev/null.
11973 Reported months ago by H. Merijn Brand.
11975 2002-10-17 Akim Demaille <akim@epita.fr>
11977 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
11979 2002-10-16 Paul Eggert <eggert@twinsun.com>
11981 * Makefile.maint (wget_files): Remove ansi2knr.c.
11982 (ansi2knr.c-url_prefix): Remove.
11984 2002-10-16 Akim Demaille <akim@epita.fr>
11986 Because of caching, some files that no longer exist and are no
11987 longer required can still cause errors.
11988 Reported by Alexandre Duret-Lutz.
11990 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
11991 to frozen files in @ARGV, as @ARGV must remain being a list of
11992 files. Rather, at M4 call sites, use this...
11993 (&files_to_options): New function.
11994 (&freeze): Use &error.
11995 (&up_to_date): If a file that was included according to the cache
11996 is no longer there, then the output is out dated.
11997 (&main): Don't even check whether a file is up to date is anyway
11998 --force is given.
11999 * tests/tools.at (autom4te cache): New.
12001 2002-10-16 Akim Demaille <akim@epita.fr>
12003 * bin/autoconf.as: Kill dead options.
12004 * bin/autoupdate.in (&parse_args): Kill old options.
12005 * bin/autoreconf.in (&parse_args): Remove dead options.
12006 Factor some code.
12007 (&autoreconf): Report the directories we enter *and leave*, so
12008 that error messages can be easily located, and use GNU Make
12009 format, so that Emacs' compile mode understands us.
12010 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12011 if some file was changed instead of `print'.
12012 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
12013 (&parse_args): Remove the dead options.
12014 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
12015 autoheader's quiet mode.
12016 (AT_CHECK_AUTOUPDATE): Likewise.
12017 * tests/tools.at (autoupdate): Adjust.
12018 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12020 2002-10-11 Akim Demaille <akim@epita.fr>
12022 No longer use CPP to check for the existing of headers: use CC to
12023 check for compilability.
12025 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
12026 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
12027 (_AC_CHECK_HEADER_NEW): Rename as...
12028 (AC_CHECK_HEADER): this.
12030 * lib/autotest/general.m4 (AT_INIT): Include the failed test
12031 numbers in the Subject suggestion.
12033 2002-10-11 Akim Demaille <akim@epita.fr>
12035 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
12036 Suggest using AC_CHECK_DECLS instead.
12038 2002-10-11 Akim Demaille <akim@epita.fr>
12040 * tests/torture.at (AC_ARG_VAR): Have configure report the value
12041 of `precious'.
12043 2002-10-11 Akim Demaille <akim@epita.fr>
12045 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
12046 file name to enable parallel executions.
12047 From Sam Varshavchik.
12049 2002-10-08 Akim Demaille <akim@epita.fr>
12051 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12052 aclocal invocation, as Gettext macros might not be visible to
12053 aclocal.
12054 Instead of blindly running autopoint, scan configure.ac (not the
12055 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12056 Reported by Paul D. Smith.
12058 2002-10-08 Paul Eggert <eggert@twinsun.com>
12060 Work around problems found when POSIXLY_CORRECT=1 is set.
12061 None of this seems to have anything to do with POSIX, really,
12062 but it's how Perl getopt works.
12063 * bin/autom4te.in (parse_args): Configure GetOpt with
12064 "permute", too.
12065 * doc/autoconf.texi (Invoking autom4te):
12066 --warning -> --warnings.
12067 * lib/autom4te.in: --warning -> --warnings.
12069 2002-09-28 Akim Demaille <akim@epita.fr>
12071 * doc/autoconf.texi (autom4te.cache): New section.
12073 2002-09-28 Akim Demaille <akim@epita.fr>
12075 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
12076 (Automake-preselections): Update.
12077 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
12079 2002-09-28 Akim Demaille <akim@epita.fr>
12081 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
12082 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
12083 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12084 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12086 2002-09-28 Akim Demaille <akim@epita.fr>
12088 * tests/torture.at (Configuring subdirectories): Be robust to
12089 users who use config.site to require for a cache: in this case,
12090 the two last configure runs, using two different sets of
12091 arguments, trigger a legitimate error.
12093 2002-09-28 Akim Demaille <akim@epita.fr>
12095 * tests/m4sh.at (Functions Support, Functions and return Support):
12096 New.
12098 2002-09-28 Akim Demaille <akim@epita.fr>
12100 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12101 autoheader are Perl programs.
12102 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12103 (autom4te): Specify that the sources are in the $srcdir.
12104 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12106 2002-09-28 Akim Demaille <akim@epita.fr>
12108 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
12109 (tm_zone): Move their rules to...
12110 * lib/autoconf/types.m4: here, using AN_ macros.
12111 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12112 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12113 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
12114 * lib/autoconf/programs.m4: here.
12115 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
12116 (ETAGS_FOR_AUTOCONF): New.
12117 Use it.
12119 2002-09-28 Akim Demaille <akim@epita.fr>
12121 * lib/autoconf/autoscan.m4: New file.
12122 * lib/autoconf/autoconf.m4: Include it.
12123 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12124 that were listed in the original autoscan.list.
12125 * lib/autoconf/headers.m4: Similarly with headers.
12126 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12127 (.m4.m4f): Don't pass --prepend-include, since that's done by
12128 tests/autom4te itself.
12129 * lib/autoscan/Makefile.am: Include freeze.mk.
12130 (autoscan.list): New target --this file is no longer a source.
12131 (autoscan.pre): New file.
12133 2002-09-28 Akim Demaille <akim@epita.fr>
12135 * bin/autoscan.in (@kinds): Make them singular.
12136 Adjust all uses.
12137 (&init_tables): When --debug, report the list of rules to ease
12138 tracking changes in autoscan.list.
12139 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12141 2002-09-28 Akim Demaille <akim@epita.fr>
12143 * lib/autoscan/functions, lib/autoscan/headers,
12144 * lib/autoscan/identifiers, lib/autoscan/makevars,
12145 * lib/autoscan/programs: Merge into...
12146 * lib/autoscan/autoscan.list: this.
12147 * bin/autoscan.in (&init_tables): Adjust.
12149 2002-09-28 Akim Demaille <akim@epita.fr>
12151 * lib/autoscan/functions, lib/autoscan/headers,
12152 * lib/autoscan/identifiers, lib/autoscan/makevars,
12153 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12154 `functions' line is now prefixed with `function:'.
12155 * bin/autoscan.in (&init_tables): Adjust.
12157 2002-09-28 Akim Demaille <akim@epita.fr>
12159 From now on, autoscan files must always map a macro name to a
12160 word: there is no `default' macro for autoscan.
12162 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12163 all.
12164 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12165 explicit.
12167 2002-09-28 Akim Demaille <akim@epita.fr>
12169 * bin/autoscan.in (%c_keywords): Remove.
12170 (&used): Keep only track of the words we might be interested in.
12171 (&output_kind): It is no longer needed to look for non active
12172 checks.
12174 2002-09-27 Akim Demaille <akim@epita.fr>
12176 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12177 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12178 * lib/autoscan/functions: Adjust.
12179 * doc/autoconf.texi (Particular Functions): Adjust.
12181 2002-09-27 Akim Demaille <akim@epita.fr>
12183 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
12184 from /tmp.
12185 Thanks to Bill Moseley and Paul Eggert.
12186 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12187 the tmpdir must be created.
12188 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12189 dir be in the build tree, instead of $TMPDIR.
12191 2002-09-27 Akim Demaille <akim@epita.fr>
12193 * bin/autoscan.in: Improve the comments.
12194 (&parse_args): Drop obsolete undocumented options.
12195 (&output_kind): Output warnings.
12196 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
12197 (getwd): Trigger a warning.
12199 2002-09-26 Akim Demaille <akim@epita.fr>
12201 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12202 Reported by Ralf Corsepius.
12203 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12205 2002-09-26 Akim Demaille <akim@epita.fr>
12207 Single suffix rules and seperated dependencies are not portable.
12209 * doc/autoconf.texi (Installation Directory Variables): Update.
12210 (Limitations of Make): Some about `Single Suffix Rules and
12211 Separated Dependencies'.
12212 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12213 (ifnames, autoscan, autom4te): Un-factor into several rules.
12215 2002-09-25 Paul Eggert <eggert@twinsun.com>
12217 * BUGS (Interoperability bugs): New section. Mention libtool
12218 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12220 2002-09-24 Paul Eggert <eggert@twinsun.com>
12222 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12223 make handles suffix-rules differently from GNU make.
12225 * bin/Makefile.am (SUFFIXES, .in): Remove.
12226 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12227 Move the body of the old .in rule here.
12229 2002-09-16 Akim Demaille <akim@epita.fr>
12231 i960 compilers create `b.out' files by default.
12232 Reported by Ralf Corsepius.
12234 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12235 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12237 2002-09-13 Paul Eggert <eggert@twinsun.com>
12239 * doc/autoconf.texi (Particular Headers): Remove obsolete
12240 reference to `struct timezone' in the description of
12241 AC_HEADER_TIME.
12243 2002-09-13 Akim Demaille <akim@epita.fr>
12245 Version 2.54.
12247 * config/config.sub, config/config.guess: Update.
12248 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12249 * Makefile.am: Adjust.
12251 2002-09-13 Akim Demaille <akim@epita.fr>
12253 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12254 reading config.log when the compiler is rejected.
12255 Suggested by Guido Draheim.
12257 2002-09-13 Akim Demaille <akim@epita.fr>
12259 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12260 (chdir_init) might hang when stat'ing mounted directories.
12261 Reported by Vance Shipley.
12263 2002-09-12 Akim Demaille <akim@epita.fr>
12265 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12266 the lists.
12268 2002-09-12 Akim Demaille <akim@epita.fr>
12270 * doc/autoconf.texi (Defining Symbols): Present two different
12271 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12272 difference between 1 argument calls, and 2-3 argument calls.
12274 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12276 * doc/autoconf.texi: Review grammar and punctuation.
12278 2002-09-11 Paul Eggert <eggert@twinsun.com>
12280 * doc/autoconf.texi: Fix minor formatting, spelling, and
12281 grammatical typos.
12282 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12283 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12284 is obsolescent.
12286 2002-09-11 Akim Demaille <akim@epita.fr>
12288 * doc/autoconf.texi (Questions): Rename as...
12289 (FAQ): this.
12290 (Defining Directories): New.
12292 2002-09-09 Akim Demaille <akim@epita.fr>
12294 * doc/autoconf.texi (Making testsuite Scripts): Update.
12295 Suggested by Nishio Futoshi.
12297 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12299 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12300 plain `@' is wanted.
12302 2002-09-09 Akim Demaille <akim@epita.fr>
12304 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12305 `duplicates', since the algorithm was too naive and could keep
12306 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12307 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12308 Reported by Ralf Corsepius.
12309 * tests/torture.at (Configuring subdirectories): Exercise these
12310 cases.
12312 2002-09-09 Akim Demaille <akim@epita.fr>
12314 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12315 looking for a replacement file.
12316 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12317 directory is relative.
12318 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12319 directory definition.
12320 Reported by Andreas Schwab and Jim Meyering.
12322 2002-09-06 Akim Demaille <akim@epita.fr>
12324 * doc/autoconf.texi (Setting Output Variables): Clarify what
12325 precious variables are.
12326 Suggested by Pontus Skoeld.
12328 2002-09-05 Akim Demaille <akim@epita.fr>
12330 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12331 (ifnames, autoscan, autom4te): Since we don't only depend on
12332 configure.ac variables (such as VERSION etc.), but also on prefix
12333 and so forth, depend on Makefile, not configure.ac.
12334 Reported by Alexandre Duret-Lutz.
12335 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12337 2002-09-05 Kevin Ryde <user42@zip.com.au>
12339 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12340 doesn't seem to be confined to ia64, just say "some versions".
12342 2002-09-04 Akim Demaille <akim@epita.fr>
12344 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12345 Automake 1.6c.
12346 * Makefile.am (maintainer-clean-local): Remove.
12347 (MAINTAINERCLEANFILES): Remove COPYING.
12349 2002-09-03 Paul Eggert <eggert@twinsun.com>
12351 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12352 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12353 Brinkmann.
12355 2002-09-03 Akim Demaille <akim@epita.fr>
12357 * configure.ac: Bump to 2.53d.
12358 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12359 as of today, on Automake's team suggestion.
12361 2002-09-03 Akim Demaille <akim@epita.fr>
12363 Version 2.53c.
12365 2002-09-02 Akim Demaille <akim@epita.fr>
12367 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12368 SITE_MACRO_DIR.
12369 * configure.ac: Disable SITE_MACRO_DIR.
12371 2002-09-02 Jim Meyering <meyering@lucent.com>
12373 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12374 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12375 Also, tweak grammar: s/make sure to/be sure to/.
12377 2002-09-02 Paul Eggert <eggert@twinsun.com>
12379 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12380 directory names are generally preferable to physical names.
12382 2002-09-02 Akim Demaille <akim@epita.fr>
12384 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12385 Reported by Raja R. Harinath.
12386 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12387 * bin/autoupdate.in: Use error instead of die.
12389 2002-09-01 Paul Eggert <eggert@twinsun.com>
12391 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12392 ordinary shell concatenation rather than echo+tr+sed command that
12393 runs afoul of a long-line-related sed bug in Solaris 8.
12395 * bin/autoheader.in (parse_args): --warning -> --warnings.
12397 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12398 stdout, as traditional "ls" does.
12399 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12400 _AC_COMPILER_EXEEXT_O): Likewise.
12401 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12403 * bin/autoconf.as: Add --prepend-include option. This patch was
12404 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12405 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12407 * bin/autoconf.in, configure: Regenerate.
12409 * doc/autoconf.texi (Special Shell Variables): Mention
12410 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12412 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12413 MAILPATH and set PS1, PS2, PS4 to default values, to work
12414 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12415 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12416 the Autoconf documentation specifies; fall back to "unset" only if
12417 this fails. Use a shell for-loop for this rather than an m4 loop,
12418 to shorten the output script.
12420 2002-08-30 Paul Eggert <eggert@twinsun.com>
12422 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12423 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12424 for the CDPATH problem. Document PWD.
12425 (Limitations of Builtins): Document the problem that "cd $foo" and
12426 "ls $foo" may refer to different directories in shells conforming
12427 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12428 example, since the old example is now out of date.
12430 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12431 FOO" and "ls FOO" talk about different directories; this catches
12432 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12433 spaghetti.
12435 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12436 of rolling our own unset.
12437 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12438 in practice we needn't worry about CDPATH if unset doesn't work.
12440 * Makefile.in, aclocal.m4, bin/Makefile.in,
12441 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,

12448 Update.
12450 * configure: Regenerate with self.

12460 failure.
12462 2002-08-29 Akim Demaille <akim@epita.fr>
12464 * lib/Autom4te/General.pm (&xqx): New.
12465 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12466 hand, which is not portable.
12467 (&error): New.
12468 * bin/autom4te.in: Use them.
12469 Use &error instead of die.
12470 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12471 Adjust.
12473 2002-08-17 Paul Eggert <eggert@twinsun.com>
12475 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12476 default list of compilers to try, since it was long ago superseded
12477 by the ksh fc builtin. Suggested by Steven G. Johnson.
12479 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12481 * doc/autoconf.texi (Invoking autom4te): End the option table,
12482 fixing a bug introduced by the previous patch.
12483 (Limitations of Make): Add a 'target lookup' subentry in the
12484 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12486 2002-07-29 Mark D. Roth <roth@feep.net>
12488 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12489 options and use $AUTOM4TE_PATH.

12498 * doc/install.texi: Include copyright symbol in copyright notice.
12500 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12501 Replace with:
12502 (AM_MAKEINFOFLAGS): New macro.
12503 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12504 * Makefile.am (INSTALL): Use the new macros.
12505 Use -o rather than --output, since "missing" does not grok --output.
12507 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12509 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12510 comments do not always work. Never trust the exit status of
12511 `make -k'.
12513 2002-07-24 Kevin Ryde <user42@zip.com.au>
12515 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12516 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

12520 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12521 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12522 apparently treats PATH="nonexistent" as if it contained ".".

12525 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12527 * doc/autoconf.texi (Limitations of Make): Mention the special

12647 so that Emacs setups GNU style for perl-mode and cperl-mode.
12649 2002-06-27 Paul Eggert <eggert@twinsun.com>
12651 * config/install-sh: Quote $src. Prefer || to test's -o option,
12652 as per "Limitations of Builtins".
12653 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
12654 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12656 * tests/mktests.sh: Use grep instead of fgrep, as per
12657 "Limitations of Builtins".
12659 2002-06-15 Paul Eggert <eggert@twinsun.com>
12661 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12662 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12663 so that we consistently test the just-built programs.
12664 * tests/wrappl.as: Likewise.
12666 2002-06-12 Paul Eggert <eggert@twinsun.com>
12668 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

12672 * bin/autoreconf.in (autoconf, autoheader): Likewise.
12673 * bin/autoscan.in (autom4te): Likewise.
12674 * bin/autoupdate.in (autom4te): Likewise.
12676 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
12677 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
12678 on Solaris 2.5.1.
12680 2002-06-11 Andreas Schwab <schwab@suse.de>
12682 * doc/autoconf.texi: Add more dir entries.
12684 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
12686 * bin/autom4te.in ($cache): Don't define using `$me', the name
12687 of the cache should not depend on the name under which autom4te
12688 was installed.
12690 2002-06-07 Akim Demaille <akim@epita.fr>
12692 * tests/tools.at (autoconf: forbidden tokens, basic)

12704 rename as...
12705 (AC_REPLACE_FNMATCH): this.
12706 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
12707 AC_FUNC_FNMATCH_GNU.
12709 2002-06-07 Akim Demaille <akim@epita.fr>
12711 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
12712 Rosetta Stone for Unix.
12714 2002-06-07 Akim Demaille <akim@epita.fr>
12716 * bin/autom4te.in (warn_forbidden): When rejecting a token,
12717 suggest m4_pattern_allow.
12718 Suggested by Adam J. Richter.
12720 2002-06-07 Akim Demaille <akim@epita.fr>
12722 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
12723 ac_config_libobj_dir.
12724 (AC_CONFIG_LIBOBJ_DIR): New.
12725 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
12726 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
12727 Use ac_config_libobj_dir to find the replacement files.
12728 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
12729 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
12730 (AC_REPLACE_FNMATCH_GNU): these.
12731 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
12732 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
12733 * tests/mktests.sh (ac_exclude_list): Don't check
12734 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
12736 2002-06-06 Paul Eggert <eggert@twinsun.com>
12738 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
12739 if ln doesn't work.
12740 * NEWS: Likewise.
12741 * doc/autoconf.texi (Configuration Links): Likewise.

12744 2002-06-05 Paul Eggert <eggert@twinsun.com>
12746 * config/config.guess, config/config.sub, config/texinfo.tex:
12747 Update from masters.
12749 2002-05-29 Paul Eggert <eggert@twinsun.com>
12751 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
12752 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.

12761 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
12762 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
12764 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
12765 * doc/autoconf.texi (Particular Programs): Document them.

12769 2002-05-27 Paul Eggert <eggert@twinsun.com>

12772 * NEWS, doc/autoconf.texi (Particular Types): Document it.
12773 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
12774 instead of AC_MBSTATE_T, which never existed.
12776 2002-05-23 Akim Demaille <akim@epita.fr>
12778 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
12779 version of Autoconf that is discussed.
12781 2002-05-22 Paul Eggert <eggert@twinsun.com>
12783 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12784 from the default list of compilers to try. Suggested by
12785 Kate Hedstrom.
12786 * NEWS: Document the above.
12787 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12789 2002-05-17 Paul Eggert <eggert@twinsun.com>
12791 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12792 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12793 This improves on an earlier suggestion by H. Peter Anvin.
12795 2002-05-16 Paul Eggert <eggert@twinsun.com>
12797 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12798 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12799 Both macros now accept an optional source-dir arg.
12800 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12802 * NEWS: Document this.
12803 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12805 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12806 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12807 not for GNU extensions; this undoes part of the 2000-11-03 change,
12808 reverting to 2.13-compatible behavior.
12809 Add new optional argument DIR.
12810 (AC_FUNC_FNMATCH_GNU): New macro.
12812 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12814 2002-05-08 Paul Eggert <eggert@twinsun.com>
12816 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12817 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12818 and it causes a 'test' syntax error if it fails.
12819 Bug reported by Stephen Gildea.
12821 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12822 If prototypes are supported, use them to check this at compile-time,
12823 instead of trying to check it at run-time. If we must do a run-time
12824 check, assume that setvbuf is standard when cross-compiling, as
12825 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12826 Bug reported by Paul D. Smith.
12828 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12829 argument specifying location of getloadavg.c. This removes a
12830 FIXME. This idea was taken from Jim Meyering's implementation in
12831 textutils.
12832 * doc/autoconf.texi (Particular Functions): Document this.
12833 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12834 that's what the code does; this fixes a bug reported by
12835 Paul D. Smith.
12837 2002-05-03 Akim Demaille <akim@epita.fr>
12839 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12840 autopoint instead of gettextize.
12841 ($uses_alocal): Rename as...
12842 ($uses_aclocal): this.
12843 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12844 Suggested by Bruno Haible.
12846 2002-05-03 Akim Demaille <akim@epita.fr>
12848 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12850 2002-04-29 Paul Eggert <eggert@twinsun.com>
12852 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12853 files to be 1 second older; just set them to be the same time.
12854 Also, sleep 1 second after the first aclocal, to work around
12855 problems with sub-second time stamps on the input files.
12857 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12859 * doc/autoconf.texi: Mention "set -e -x" lossage
12860 under node "Limitations of Builtins".
12862 2002-04-29 Akim Demaille <akim@epita.fr>
12864 * doc/install.texi: Better wording for setting variables when
12865 running configure.
12866 From Christian Cornelssen.
12868 2002-04-29 Akim Demaille <akim@epita.fr>
12870 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12871 of lack of $LINENO support, then the test will compare the $LINENO
12872 in testsuite vs. the lineno in the test file. This is wrong, of
12873 course.
12874 Be sure to protect it.
12875 Reported by Patrick Welche.
12877 2002-04-25 Akim Demaille <akim@epita.fr>
12879 * doc/autoconf.texi (Obsolete Macros): Typo.
12880 Reported by Vladimir Volovich.
12882 2002-04-25 Akim Demaille <akim@epita.fr>
12884 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12885 than some of the input files, hence, on the second run of aclocal,
12886 if some of its input are younger, make them older.
12887 Suggested by Paul Eggert.
12889 2002-04-25 Akim Demaille <akim@epita.fr>
12891 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12892 Thanks to Paul Eggert.
12894 2002-04-25 Akim Demaille <akim@epita.fr>
12896 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12897 and ac_subst_vars be sh variables containing the list of
12898 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12899 DEFAULT diversion.
12900 (_AC_INIT_PREPARE): Use them to log them.
12901 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12902 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the

12909 * bin/autoreconf.in (autoreconf): Run automake after autoconf and

12915 * bin/autoheader.in (parse_args): --warning takes an argument.

12965 Minor spelling and grammar fixes.
12967 * doc/autoconf.texi: Follow the outline suggested in the GNU
12968 Sample Texts sections of the Texinfo 4.2 manual. Most
12969 importantly, this makes sure that the copyright notices appear in
12970 all output formats. You probably need Texinfo 4.2 to generate
12971 the manual now.
12973 Fix some bugs when using "$@" when there might be zero positional
12974 arguments in cases where this matters.

13009 workaround for ${1+"$@"}.
13010 * doc/autoconf.texi (Shell Substitutions): Explain it.
13011 From Oliver Kiddle and Peter Stephenson.
13013 Have M4sh perform minimal shell sanitizing.
13015 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13016 part into...
13017 (_AS_PREPARE): this new macro.
13018 (AS_PREPARE): New.
13019 (AS_INIT): Invoke AS_SHELL_SANITIZE.
13020 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
13022 Adjust Autoconf and Autotest.
13024 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
13025 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
13026 * lib/autotest/general.m4 (AT_INIT): Likewise.
13027 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
13028 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
13029 AS_SHELL_SANITIZE.
13031 Use this M4sh to generate Autoconf's shell scripts.
13033 * tests/wrapsh.as: New, precursor of wrapsh.in.
13034 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13035 on Autotest and M4sh.
13036 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13037 (wrapsh.in): New target.
13038 * bin/autoconf.as: New, precursor of autoconf.in.
13039 (autoconf.in): New target.
13041 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

13044 with indented comments in rules.
13046 2002-04-09 Andreas Schwab <schwab@suse.de>
13048 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
13049 ac_top_builddir when setting ac_abs_top_builddir.
13051 2002-04-06 Kevin Ryde <user42@zip.com.au>
13053 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
13054 (Portable Shell): Cross reference to Systemology.
13056 2002-04-05 Akim Demaille <akim@epita.fr>
13058 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
13059 directories when descending in a SUBDIRS.

13069 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13070 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13071 Use dnl, not the KILL diversion.
13072 Extracted from...
13073 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13074 (AC_CONFIG_LINKS): here.
13075 Adjust.
13076 Don't use the KILL diversion, as it kills spurious output, which
13077 results in failures being hidden.
13078 Use m4_defn where appropriate.
13079 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13080 after the second argument.
13081 Use m4_defn.
13082 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13083 syntax, as it is provided by M4sugar.
13084 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13086 2002-04-03 Andreas Schwab <schwab@suse.de>
13088 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

13092 aclocal.

13100 (_AC_COMPILER_OBJEXT): Use them.
13101 Fixes Debian #138666.
13103 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13105 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

13108 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13109 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13110 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13111 (AC_C_CONST): Same.
13112 (AC_C_INLINE): Same.
13113 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
13114 * doc/autoconf.texi, NEWS: Document.
13115 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
13116 AC_C_CROSS.

13123 2002-03-28 Kevin Ryde <user42@zip.com.au>
13125 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13126 to avoid versions of HP C which don't allow that.
13128 2002-03-27 Paul Eggert <eggert@twinsun.com>
13130 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13131 (AS_SHELL_SANITIZE): Invoke it.
13132 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
13134 2002-03-26 Akim Demaille <akim@epita.fr>
13136 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13138 2002-03-26 Akim Demaille <akim@epita.fr>
13140 * doc/autoconf.texi (Introduction): The GNATS base moved.
13142 2002-03-25 Paul Eggert <eggert@twinsun.com>
13144 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13145 as POSIX requires, as it doesn't work with Zsh.
13146 * doc/autoconf.texi (Assignments): Document the problem.
13148 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13150 * doc/autoconf.texi (Limitations of Make): Mention more issue
13151 about VPATH, overriding of macros in sub-makes, and handling of
13152 SHELL.
13154 2002-03-21 Paul Eggert <eggert@twinsun.com>
13156 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13157 problem with here-document buffer boundaries.
13159 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13160 when reinvoking the shell, to work around problems with installers
13161 who put strange things like "cd" commands in their environments.
13163 2002-03-19 Akim Demaille <akim@epita.fr>
13165 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13166 From Aaron Ucko.
13168 2002-03-19 Akim Demaille <akim@epita.fr>
13170 * bin/autoscan.in (scan_file): Specify the location in `&used'
13171 invocations.
13172 From Nicolas Joly.
13174 2002-03-19 Akim Demaille <akim@epita.fr>
13176 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13177 From Nishio Futoshi.
13179 2002-03-19 Akim Demaille <akim@epita.fr>
13181 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

13185 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13186 (Limitations of Usual Tools): Add mkdir section.
13188 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13189 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13190 back on AS_DIRNAME to compute prefixes otherwise; this is
13191 roughly what mkinstalldirs does. That way, we need not have
13192 our own filename disassembler. The old disassembler did not
13193 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13195 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13196 Create at_test_all by a series of assignments,
13197 not by a single assignment of a long string. The latter causes ksh
13198 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13199 presumably because of a buffer overrun.
13201 2002-03-14 Paul Eggert <eggert@twinsun.com>
13203 * lib/autotest/general.m4 (at_times_skip):
13204 Renamed from at_times. Now a boolean.
13205 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13206 says 'times: not found'.
13208 2002-03-14 Akim Demaille <akim@epita.fr>
13210 * bin/autoreconf.in (&study_gettextize): New.
13211 (&autoreconf): Handle newest gettextize.
13212 Rerun aclocal if needed.
13213 Suggested by Andreas Schwab.
13215 2002-03-13 Akim Demaille <akim@epita.fr>
13217 * doc/autoconf.texi (Special Shell Variables): More about IFS.

13222 Add information about stdint.h and inttypes.h from Paul Eggert.
13224 2002-03-13 Akim Demaille <akim@epita.fr>
13226 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13227 -p'.
13228 From Bob Proulx.
13230 2002-03-12 Akim Demaille <akim@epita.fr>
13232 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13233 m4_require.
13235 2002-03-11 Andreas Schwab <schwab@suse.de>
13237 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13238 does not do it if --with-lispdir is given.
13240 2002-03-08 Akim Demaille <akim@epita.fr>
13242 Version 2.53.
13244 2002-03-08 Akim Demaille <akim@epita.fr>
13246 * doc/autoconf.texi (Subdirectories): Clarify that the
13247 subdirectory should exist.
13249 2002-03-08 Akim Demaille <akim@epita.fr>
13251 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13253 2002-03-08 Akim Demaille <akim@epita.fr>
13255 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13256 aliases the actual variables, and modifications of the former
13257 affect the latter.
13259 2002-03-08 Akim Demaille <akim@epita.fr>
13261 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13262 because of C-c: have m4 output in tmp files, then mv them.
13264 2002-03-08 Akim Demaille <akim@epita.fr>
13266 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

13276 * doc/autoconf.texi (Specifying Names): Clarification suggested by
13277 Kevin Ryde.
13279 2002-03-05 Akim Demaille <akim@epita.fr>
13281 Version 2.52i.
13283 2002-03-04 Akim Demaille <akim@epita.fr>
13285 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13286 * lib/autoconf/general.m4 (AC_INIT): More informative error
13287 message for LIBOBJ.
13289 2002-03-04 Akim Demaille <akim@epita.fr>
13291 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13292 parallel builds.
13294 2002-03-04 Akim Demaille <akim@epita.fr>
13296 * doc/autoconf.texi (Transforming Names): Equality between target
13297 and host is irrelevant.
13298 (Specifying Names, Canonicalizing): Remove all references to the
13299 backward compatibility hooks. Rather, collect them all into...
13300 (Hosts and Cross-Compilation): this new section.
13301 * doc/install.texi (System Type): Ditto.
13302 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13303 that `--host' implies cross-compilation.
13305 2002-03-04 Akim Demaille <akim@epita.fr>
13307 * doc/autoconf.texi (Evaluation Macros): New.
13308 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13309 useless.
13310 (_m4_foreach): Define the variant with immediate evaluation so
13311 that it contains exactly the items, not an expression which
13312 evaluation is the current item.
13313 (m4_re_string, m4_re_word): Don't over quote them.
13315 2002-03-04 Akim Demaille <akim@epita.fr>
13317 Instead of having stacking `shift's evaluated at the end, let
13318 `foreach' loops immediately evaluate them.
13320 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13321 $*. This is the n-th time I change my mind, but hopefully this is
13322 the last...
13323 (m4_lquote): New.
13324 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13325 efficient.
13326 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13327 it was only a hack for m4_text_wrap.
13328 (m4_car2): Remove, replaced by...
13329 (m4_cdr): New.
13330 (_m4_foreach): Adjust.
13331 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13332 m4_bpatsubst for clarification.

13381 2002-02-07 Akim Demaille <akim@epita.fr>

13386 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13387 variable when looking for the prefix program.
13388 Now it also works for shell variables.
13390 2002-02-07 Akim Demaille <akim@epita.fr>
13392 * doc/autoconf.texi (Limitations of Builtins): More about
13393 case/esac.
13395 2002-02-06 Akim Demaille <akim@epita.fr>
13397 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
13398 case/esac, some shells don't support it.
13399 Reported by Zack Weinberg.
13400 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
13402 2002-02-06 Akim Demaille <akim@epita.fr>
13404 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
13405 sure not to introduce newlines in at_groups.
13406 * lib/autotest/Makefile.am (autotest.m4f): Typo.
13408 2002-02-06 Akim Demaille <akim@epita.fr>
13410 * tests/torture.at (Configuring subdirectories): Skip if aclocal
13411 is not available.
13413 2002-02-05 Paul Eggert <eggert@twinsun.com>
13415 * doc/autoconf.texi (Specific Compiler Characteristics):
13416 Describe HP-UX cc bug workaround more accurately.
13417 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13418 not unsigned long.
13419 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13420 cross-compilers, too. This undoes some of the most recent change
13421 to this file.
13423 2002-02-05 Akim Demaille <akim@epita.fr>
13425 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13426 to make sure they are up to date when `check' is run.
13428 2002-02-05 Akim Demaille <akim@epita.fr>
13430 * doc/autoconf.texi (Making testsuite Scripts): Document
13431 package.m4.
13433 2002-02-05 Akim Demaille <akim@epita.fr>
13435 * lib/freeze.mk: New.
13437 2002-02-05 Akim Demaille <akim@epita.fr>
13439 Implement `autom4te --freeze'.
13441 * bin/autom4te.in (&freeze): New.
13442 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13443 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13445 2002-02-05 Akim Demaille <akim@epita.fr>
13447 * bin/autom4te.in (&parse_args): Implement `frozen files are
13448 optional are the sum of the previous files on the command line'.
13449 Also, pass `--reload-state=' on them, so...
13450 (handle_m4): don't.
13451 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13452 (M4sh): Rely on M4sugar.
13453 (Autotest, M4sh, M4sugar): Use frozen files.
13455 2002-01-31 Akim Demaille <akim@epita.fr>
13457 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13458 * doc/autoconf.texi (Initializing configure): Adjust.
13460 2002-01-30 Akim Demaille <akim@epita.fr>
13462 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13463 alphanumeric to `-' instead of `_'.
13465 2002-01-30 Akim Demaille <akim@epita.fr>
13467 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13468 for plain code, the other for cross-compilation code. The latter
13469 is now run with GCC only.
13470 * doc/autoconf.texi (Compilers and Preprocessors): New.
13472 2002-01-30 Akim Demaille <akim@epita.fr>
13474 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13475 values.
13476 * doc/autoconf.texi (Initializing configure): Explain how to
13477 change AC_INIT default values.
13479 2002-01-29 Akim Demaille <akim@epita.fr>
13481 * tests/torture.at (Configuring subdirectories): Use configure.in,
13482 so that aclocal 1.4 works.
13483 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13485 2002-01-28 Akim Demaille <akim@epita.fr>
13487 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13488 needs an argument.
13490 2002-01-28 Akim Demaille <akim@epita.fr>
13492 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13493 AUTOTEST_PATH *after* it was set.
13494 Don't put `.' in the PATH: the user should be precise and `./' if
13495 needed. In addition, given that the test suite does some `cd', if
13496 `.' is in the path, the `tested programs' sections will report
13497 programs found in the test suite's directory, while during the
13498 tests (performed in their own directory), these programs are no
13499 longer visible. In other words, the results is confusing and
13500 useless.
13501 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13503 2002-01-24 Akim Demaille <akim@epita.fr>
13505 Version 2.52g.
13507 2002-01-24 Akim Demaille <akim@epita.fr>
13509 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
13510 * doc/autoconf.texi: Finally add Akim as an author.
13512 2002-01-24 Akim Demaille <akim@epita.fr>
13514 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13515 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13516 Bourne. Use /bin/sh.
13517 From Andreas Buening.
13519 2002-01-24 Akim Demaille <akim@epita.fr>
13521 * config/config.guess, config/config.sub, config/texinfo.tex:

13529 * config/missing.m4, config/sanity.m4, config/select.m4,
13530 * config/strip.m4: Remove, to ease sync'ing with any version of
13531 Automake.
13533 2002-01-24 Akim Demaille <akim@epita.fr>
13535 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13536 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13537 Reported by Geir Ove Myhr.
13539 2002-01-21 Akim Demaille <akim@epita.fr>
13541 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13543 2002-01-21 Akim Demaille <akim@epita.fr>
13545 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13546 message on invalid options.
13547 * bin/autom4te.in (parse_args): Don't use
13548 Autoconf::General::getopt with non valid options.
13550 2002-01-17 Jim Meyering <meyering@lucent.com>
13552 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13553 $ac_cv_exeext so we don't use an old, invalid, cached value.
13555 2002-01-11 Akim Demaille <akim@epita.fr>
13557 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13558 Meyering.

13560 limitation.

13564 2002-01-06 Akim Demaille <akim@epita.fr>
13566 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13567 package.m4, since is really depends upon configure.ac, not
13568 configure.
13569 * doc/autoconf.texi (testsuite Scripts): Adjust.
13570 * tests/Makefile.am (package.m4): New.
13571 EXTRA_DIST it since its a source.
13573 2002-01-06 Akim Demaille <akim@epita.fr>
13575 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13576 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13577 and PACKAGE_BUGREPORT from here...
13578 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13579 arguments.
13580 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13581 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13582 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13583 * tests/tools.at (autoheader): Adjust.
13584 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13586 2002-01-06 Akim Demaille <akim@epita.fr>

13594 From Olly Betts.
13596 2001-12-18 Kevin Ryde <user42@zip.com.au>
13598 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13599 sometimes needing writable input.
13601 2001-12-17 Jim Meyering <meyering@lucent.com>
13603 * doc/autoconf.texi (New Macros): Tweak wording.
13605 2001-12-14 Akim Demaille <akim@epita.fr>
13607 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13608 trailing files, don't apply `-rf' to files which might not be
13609 created by configure (core, core.*, and *.core), but just `rm -f'.
13610 Suggested by Jonathan Kamens.
13612 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13614 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13616 2001-12-14 Akim Demaille <akim@epita.fr>
13618 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13620 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13622 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13623 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13624 abs_srcdir, top_srcpath to abs_top_srcdir.
13625 (_AC_OUTPUT_FILES): Adjust.
13626 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13627 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13628 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13630 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13632 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13633 C/Fortran linking on HP/UX, by extracting the Fortran library
13634 search path from the LPATH line in the $F77 -v output.
13636 2001-12-12 Kevin Ryde <user42@zip.com.au>
13638 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13639 forbidden file descriptors table.
13641 2001-11-26 Akim Demaille <akim@epita.fr>
13643 * bin/autoscan.in (%c_keywords): Build it at top level.
13644 Map to 1 in order to simplify its uses.
13646 2001-11-26 Akim Demaille <akim@epita.fr>
13648 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13649 Remove $filepath, useless.
13650 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13651 variables, they are really part of the tokens.
13652 Split the input line on spaces and then look for tokens.
13653 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13654 because of `lex$U.$(OBJEXT)'.
13655 (&scan_files): Use "@list" instead of join.
13656 * doc/Makefile.am (CLEANFILES): Add *.fns.
13658 2001-11-26 Akim Demaille <akim@epita.fr>
13660 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13661 Remove, replaced by...
13662 * tests/wrappl.in: Be common for all the Perl executables.
13663 In particular autoscan and autoheader want -I.
13664 * configure.ac: Adjust.
13665 * lib/autoscan/headers: errno.h is portable.
13667 2001-11-26 Akim Demaille <akim@epita.fr>
13669 * bin/autoscan.in (used): New.
13670 Use it.

13674 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13675 directives.
13676 (&scan_sh_file): Remove a duplicate pattern.
13677 (&check_configure_ac): Use long options.
13678 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13680 2001-11-26 Akim Demaille <akim@epita.fr>
13682 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13683 Before, having a line containing the opening of a multi line
13684 comment made the whole line be ignored.
13686 2001-11-26 Akim Demaille <akim@epita.fr>
13688 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13689 (testsuite Scripts): Be one of its subsection.
13690 (Autotest Logs): New.
13692 2001-11-26 Akim Demaille <akim@epita.fr>
13694 Test groups are now run two directories deeper.
13696 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13697 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13698 at_top_builddir.
13699 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13700 top_srcdir, builddir and top_builddir.
13701 Use `at_*dir' relatively to the directory containing the
13702 suite, use `*dir' when relatively to the current group dir.
13704 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13706 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13707 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13708 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13709 spelling errors.
13711 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13713 * doc/autoconf.texi (Using System Type): Add an example of `case
13714 $host' usage so people quit using `case $target' everywhere.
13716 2001-11-22 Akim Demaille <akim@epita.fr>
13718 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13719 spotted by Jim Meyering.
13721 2001-11-16 Paul Eggert <eggert@twinsun.com>
13723 This patch implements a `long double' suggestion by Oliver Kiddle.
13725 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13726 static, to catch errors if the value isn't known at compile-time
13727 and the compiler supports dynamic arrays. Change its name from
13728 `_array_' to `test_array' to avoid potential name clashes.
13729 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13730 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13731 better than double. Catch a bug in GCC 2.95.2 x86.
13732 * doc/autoconf.texi (C Compiler): Document the above.
13733 * NEWS: Likewise.
13735 2001-11-13 Akim Demaille <akim@epita.fr>
13737 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13738 hand.
13739 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13741 2001-11-13 Akim Demaille <akim@epita.fr>
13743 * lib/autotest/general.m4 (AT_INIT): After having run the test
13744 group, go back to the initial directory, not to at_suite_dir.
13746 2001-11-13 Akim Demaille <akim@epita.fr>
13748 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13749 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13750 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13751 option.
13752 (AT_CHECK_CONFIGURE): Use absolute paths.
13753 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13754 The problem is still the old one: there is no means in M4 (that I
13755 know about) to create a defining macro, because there is no means
13756 to create `$1' etc., therefore, the defining macro ``swallows''
13757 all the arguments meant to the defined macro.
13759 2001-11-13 Akim Demaille <akim@epita.fr>
13761 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13762 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13763 configure.ac.
13764 * tests/aclocal.m4: Remove, as it is no longer used.
13766 2001-11-13 Akim Demaille <akim@epita.fr>
13768 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13769 variable names when referring to a single test group, or to
13770 `suite' when referring to the whole test suite.
13771 `at_last_test' is removed: m4 compute at_format itself.
13772 (at_stdout, at_stder1, at_stderr): New variables.
13773 (AT_CHECK): Use them.
13775 2001-11-13 Akim Demaille <akim@epita.fr>
13777 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13778 in PATH.
13779 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13780 Do it as soon as a test fails, don't wait till the end of the test
13781 suite.
13782 Don't remove $as_me.[0-9]*, since these files no longer exist.
13784 2001-11-13 Akim Demaille <akim@epita.fr>
13786 * tests/tools.at: Use absolute paths, since we are no longer run
13787 in place.
13789 2001-11-13 Akim Demaille <akim@epita.fr>
13791 Now that tests are running in their own private dir, there is no
13792 need to list the files to remove at the end of tests groups.
13794 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13795 (AT_data_files, at_data_files): Remove.
13796 (AT_CLEANUP, AT_DATA): Simplify.
13797 (AT_INIT): Adjust.
13798 Remove the group dir if !debug && !failed.
13799 * tests/atspecific.m4: Adjust.
13801 2001-11-13 Akim Demaille <akim@epita.fr>
13803 Start a new layout for Autotest: `testsuite' creates
13804 `testsuite.dir' in which the at-check-line etc. files are to be
13805 found, and `testsuite.dir/003' where the test group 3 is run.
13807 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13808 at_check_line_file, at_format, at_test_normalized, at_group_dir
13809 are new variables.
13810 Create the directories.
13811 Use absolute paths for at- files.
13812 (AT_CHECK): Adjust.
13814 2001-11-11 Michael Matz <matz@kde.org>
13816 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13817 (m4_car2): New.
13818 (m4_car): Properly quote arguments.
13820 2001-11-13 Akim Demaille <akim@epita.fr>
13822 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13823 with stricter rules on LIBOBJS.
13825 2001-11-12 Paul Eggert <eggert@twinsun.com>
13827 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13828 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13829 __PROTOTYPES too.
13831 2001-11-12 Akim Demaille <akim@epita.fr>
13833 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13835 2001-11-12 Akim Demaille <akim@epita.fr>
13837 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13838 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13839 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13840 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13841 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13842 specify to what the macro should be defined (typically to 1).
13844 2001-11-12 Akim Demaille <akim@epita.fr>
13846 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13847 From Jim Meyering.
13849 2001-11-12 Akim Demaille <akim@epita.fr>
13851 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13852 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the

13860 the test suites.
13862 2001-11-08 Akim Demaille <akim@epita.fr>
13864 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13865 that we can trace macros from aclocal.m4.
13866 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13867 obsoleted, and redirect to the former anyway.
13868 Reported by Ralf Corsepius.
13870 2001-11-08 Akim Demaille <akim@epita.fr>
13872 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13873 processed only if present.
13874 * tests/torture.at (Configuring subdirectories): Use autoreconf
13875 instead of successive calls to autoconf.
13876 Add a nonexistent subdirectory to exercise the patch above.
13877 Reported by Ralf Corsepius.
13879 2001-11-08 Kevin Ryde <user42@zip.com.au>

13891 Read m4_pattern_forbid with messages.
13893 2001-11-05 Akim Demaille <akim@epita.fr>
13895 * bin/autom4te.in (--normalize): Remove.

13902 From Nicolas Joly.
13904 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13906 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

13938 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13939 Don't look for aclocal flags if we already know aclocal is not
13940 used.
13941 Move aclocal.m4t only if it exists.
13942 Reported by Ezra Peisach.
13944 2001-11-03 Akim Demaille <akim@epita.fr>
13946 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13947 passed on command line, defaulting to ./configure.ac if present.
13948 (&maybe_autoreconf, File::Find): Remove, unused.
13949 (&autoreconf): If autoconf is not used, don't try to trace.
13951 2001-11-02 Akim Demaille <akim@epita.fr>
13953 * configure.ac: Bump to 2.52g.
13955 2001-11-02 Akim Demaille <akim@epita.fr>
13957 Version 2.52f.
13959 2001-11-02 Akim Demaille <akim@epita.fr>
13961 * config/config.guess, config/config.sub, doc/standards.texi:
13962 * config/lispdir.m4: Update from masters.
13963 * configure.ac: Bump to 2.52f.
13965 2001-11-02 Akim Demaille <akim@epita.fr>
13967 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13968 Don't run aclocal when aclocal.m4 is not from aclocal.
13969 From Ezra Peisach.
13970 Don't run libtoolize and gettextize if --install is not given.
13972 2001-11-01 Paul Eggert <eggert@twinsun.com>
13974 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13975 be invoked before _AS_LINENO_PREPARE.
13976 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13977 than character ranges.
13979 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13980 invoking AS_BASENAME. Set the locale variables to 'C' if
13981 possible, as POSIX requires this to get the traditional
13982 behavior.
13983 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13985 2001-10-31 Paul Eggert <eggert@twinsun.com>
13987 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13988 with {}, as that triggers a bug in Bash 2.05.
13990 (_AS_LINENO_PREPARE): Use Sed rather than
13991 Awk. Fix the sed prepass to work even if there are multiple
13992 instances of $LINENO on the same line. Do not substitute for
13993 other variables like $LINENOT. Do not check file dates; such a
13994 check is unreliable on sufficiently fast machines, and removing
13995 the check makes the code simpler and more reliable. Check for
13996 output and chmod failures.
13998 * doc/autoconf.texi (Special Shell Variables): Document
13999 the above.
14001 2001-10-31 Akim Demaille <akim@epita.fr>
14003 * tests/Makefile.am (atconfig): Remove this target, Automake
14004 handles it now.
14006 2001-10-31 Akim Demaille <akim@epita.fr>
14008 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14009 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14010 provided, while it is optional.
14011 * configure.ac: Adjust.
14013 2001-10-26 Paul Eggert <eggert@twinsun.com>
14015 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14016 lib/Autom4te/Struct.pm:
14017 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14018 with 5.005_02.
14020 * doc/autoconf.texi (Special Shell Variables): Document some
14021 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14023 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14024 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14025 eval $LINENO is not portable in practice.
14027 2001-10-24 Akim Demaille <akim@epita.fr>
14029 * lib/Autom4te/General.pm (backname): New.
14031 2001-10-24 Akim Demaille <akim@epita.fr>
14033 * m4/: Remove, merged into...
14034 * config/: here.
14036 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14038 * doc/autoconf.texi (Shellology): Mention the problems with bash
14039 2.05's use of ANSI quoting in its `set' builtin.
14041 2001-10-22 Paul Eggert <eggert@twinsun.com>
14043 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14044 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14045 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14046 POSIX decided to standardize on the int flavor of strerror_r.
14047 Always do char* test, as there's no reason not to.
14048 Assign to a char* var, to catch strerror_r that returns int*.
14050 * doc/autoconf.texi (Particular Functions):
14051 Document the above changes. Also, document the fact that
14052 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14054 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14056 2001-10-20 Akim Demaille <akim@epita.fr>
14058 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14059 the executable was missing from the log.

14063 * lib/Autom4te/General.pm (&update_file): If destination is
14064 unchanged, remove the source.
14065 (&up_to_date_p): Don't be verbose, be debug.
14066 * bin/autoreconf.in: No longer support --m4dir.
14067 (&autoreconf): Display the full path of the configure.ac we are
14068 studying.
14069 Trace it only once.
14070 Be sure to honor --force with gettextize.
14071 Always run aclocal.
14072 * doc/autoconf.texi: Adjust.
14074 2001-10-20 Akim Demaille <akim@epita.fr>
14076 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14077 Remove, dead.
14078 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14079 `intl' is already present, as it refuses unless --force.
14080 (&parse_args): Use -I, --include instead of the old Autoconf
14081 options.
14082 ($localdir, $autoconf_dir): Remove.
14083 (@include): New.
14084 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14086 2001-10-19 Jens Petersen <petersen@redhat.com>

14094 file in @configure_input@.
14095 Don't mention `automatically' in addition to `generated'.
14096 * tests/torture.at (#define header templates): Adjust.
14098 2001-10-19 Akim Demaille <akim@epita.fr>
14100 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
14101 comment, explain how to install automatic mode selection.
14102 From Russ Allbery.
14104 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14106 * bin/autoreconf.in (autoreconf): Display the path to the
14107 configure.ac being studied.
14109 2001-10-18 Paul Eggert <eggert@twinsun.com>
14111 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14112 long, to work around a bug in the HP C compiler version HP92453-01
14113 B.11.11.23709.GP.
14115 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14116 (AS_BASENAME_EXPR): New macro.
14117 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14118 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14119 and fall back on 'sed' only if the other two fail. This makes
14120 AS_BASENAME act more like AS_DIRNAME.
14121 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14122 contains white space.
14123 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14124 Use AS_DIRNAME, since I think it's now DOS-friendly.
14125 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14126 Allow "dirname //FOO" to return either / or //, as POSIX allows
14127 either behavior.
14129 2001-10-10 Akim Demaille <akim@epita.fr>
14131 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
14132 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
14133 From Eric Sharkey.

14137 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14138 m4_define, since...

14256 * tests/tools.at (AT_DATA_FORBIDDEN): New.

14262 * doc/autoconf.texi (config.status Invocation):
14263 CONFIG_SHELL defaults to a shell that supports LINENO if available.

14267 empty, and if we can find a shell that does support LINENO,
14268 then set CONFIG_SHELL to that shell and then re-execute
14269 ourselves with CONFIG_SHELL.
14271 2001-10-05 Paul Eggert <eggert@twinsun.com>
14273 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

14277 2001-10-05 Akim Demaille <akim@epita.fr>
14279 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

14313 somewhat-incorrect example involving "." and "/".
14315 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
14316 compatibility with POSIX shells.
14318 2001-10-02 Akim Demaille <akim@epita.fr>
14320 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
14321 instead of exec'ing to preserve $0 and $@.
14323 2001-10-01 Akim Demaille <akim@epita.fr>
14325 * tests/testsuite (AT_INIT) <at_pass_list>: New.
14326 Don't run twice the same test.
14328 2001-10-01 Akim Demaille <akim@epita.fr>
14330 * lib/autotest/general.m4 (AT_INIT) <--help>: Catch up with reality.
14331 No longer output the list of tests.

14333 <--full-help>: Remove.
14334 Complete the short/long options duality.
14335 Various small adjustments.
14337 2001-10-01 Akim Demaille <akim@epita.fr>
14339 * doc/autoconf.texi: Use @kbd for user input.

14342 2001-09-30 Paul Eggert <eggert@twinsun.com>
14344 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
14345 Don't use nested parenthesization. This patch was originally
14346 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
14347 but somehow it didn't get incorporated then.
14348 * doc/autoconf.texi (Limitations of Usual Tools):
14349 Clarify remark about sed and nested parenthesization.
14351 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
14352 Report an error if the size cannot be determined even though
14353 the type exists.
14354 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14355 Check for `expr' arithmetic overflow, and for compilation failure,
14356 and invoke a new argument $4 if either is discovered.
14357 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14358 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
14360 2001-09-28 Akim Demaille <akim@epita.fr>

14368 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
14369 (AT_TESTED): this.
14370 (AT_INIT): More the wrapped section to where it will be expanded.
14371 Output `AT_tested' only when existing.
14372 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
14374 2001-09-27 Akim Demaille <akim@epita.fr>
14376 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
14377 generates too many bug reports.
14379 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
14380 status when executing the ACTION-IF-FALSE.
14381 * tests/base.at (AC_TRY_*): Rename as...

14387 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
14388 * tests/c.at (Extensions, C keywords)
14389 (Broken/missing compilers, AC_PROG_CPP with warnings)
14390 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
14391 (AC_PROG_CPP requires AC_PROG_CC): here and...
14392 * tests/fortran.at (GNU Fortran 77): there.
14393 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14394 AC_TRY_RUN is about compilation, not shell commands.
14395 (Test Programs): AC_TRY_RUN works as used to be advertised.
14397 2001-09-27 Akim Demaille <akim@epita.fr>
14399 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
14400 Raja R Harinath:
14401 Be sure to detect when $LINENO always returns the same value.
14402 Look for the original script, basename($0) is certainly not
14403 enough.
14404 Pass the CLI arguments to `$as_me.lineno'.
14406 2001-09-25 Akim Demaille <akim@epita.fr>
14408 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

14416 of --language now.
14418 2001-09-23 Akim Demaille <akim@epita.fr>
14420 * doc/autoconf.texi (Top): Wrap in @ifnottex.
14422 2001-09-23 Akim Demaille <akim@epita.fr>
14424 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
14425 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
14426 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
14427 builddir, buildpath, top_builddir, and top_buildpath.
14428 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
14429 the current directory.
14430 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
14431 variables *before* changing the current directory.
14432 Skip nonexistent dirs.

14434 variables.
14436 * lib/autotest/general.m4: Do not reset AT_victims.
14437 Don't compute at_srcdir nor at_top_srcdir.
14439 * tests/tools.at: Hence use top_srcdir.
14441 * tests/Makefile.am, tests/autoconf, tests/autoheader,
14442 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14443 Remove.
14444 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
14445 * tests/wrapsh.in, tests/autoupdate.in: New.
14446 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
14447 * configure.ac: Build the position independent wrappers.
14449 * man/Makefile.am: Now that test wrappers are position
14450 independent, use them and drop dark envvar magic.
14452 2001-09-23 Akim Demaille <akim@epita.fr>
14454 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14455 (Programming in M4sh): this.
14456 Promote to @section.
14458 2001-09-23 Akim Demaille <akim@epita.fr>
14460 * lib/autotest/general.m4 (AT_INIT): Dump config.log last.

14472 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix shell
14473 over-escaping.

14485 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
14487 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

14496 2001-09-22 Akim Demaille <akim@epita.fr>
14498 * lib/autoconf/autotest.m4: Create `package.m4'.
14499 * tests/Makefile.am (package.m4): Remove.
14501 2001-09-22 Akim Demaille <akim@epita.fr>
14503 Rely on `$LINENO' when possible instead of `__oline__'.
14505 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14506 `$LINENO' support replacement when not supported.
14507 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14508 them explicitly to be sure they are not output before this section
14509 (via m4_require). Cosmetic only.
14510 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14511 * lib/autoconf/programs.m4: Replace all the occurrences of
14512 `__oline__' with `$LINENO'.
14513 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
14515 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14517 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14518 character (u: -> ue) in a code comment.
14519 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14520 it works.
14522 2001-09-21 Akim Demaille <akim@epita.fr>
14524 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14525 Suggested by Jim Meyering.
14527 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14529 * lib/autoconf/programs.m4: Use extensions listed in
14530 $ac_executable_extensions when looking for programs.
14532 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14534 * lib/autoconf/general.m4: Fix a small Englisho.
14535 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
14536 setting up ac_dir_suffix and ac_top_builddir.
14537 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14539 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14541 * doc/autoconf.texi (File System Conventions): Clarify the use of
14542 PATH_SEPARATOR.
14543 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14544 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14545 be used instead of ':'.
14546 * lib/autotest/general.m4: Replace occurrences of ':' in
14547 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14549 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14551 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14552 arguments. Fixed a typo.
14554 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14556 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14557 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14559 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14561 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14562 * bin/autoupdate.in: Ditto.
14563 * bin/autoheader.in: Reworded a few comments.
14564 * bin/autoconf.in: Reworded help text for a few options.
14565 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14566 * bin/autoscan.in, bin/autoupdate.in: Ditto.
14568 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14570 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14571 already have $file). Set output files to binary mode (helps avoid
14572 CR issues on DOSish systems).
14574 2001-09-19 Akim Demaille <akim@epita.fr>
14576 * lib/autotest/general.m4: Englishoes.
14577 From Tim Van Holder and Alexey Mahotkin.
14579 2001-09-18 Paul Eggert <eggert@twinsun.com>
14581 * doc/autoconf.texi (Common Shell Constructs): New node,
14582 documenting AS_DIRNAME.
14583 (Limitations of Usual Tools): Refer to it when discussing dirname.
14584 Also, update discussion of POSIX standard to reflect latest draft.
14586 * lib/autoconf/c.m4:
14587 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14589 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14590 Do not pass a first argument with leading '-'
14591 to expr, by parenthesizing initial integers that might be negative.
14593 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14594 now merely checks whether it is an error to pass an argument
14595 to getpgrp.
14597 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14598 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14599 whether it is a (compile-time) error to pass an argument to
14600 getpgrp. This simpler test supports the revised documentation,
14601 and is all that AC_FUNC_GETPGRP's users really need.
14603 2001-09-18 Akim Demaille <akim@epita.fr>
14605 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14607 2001-09-18 Akim Demaille <akim@epita.fr>
14609 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
14610 `{}'.
14611 * lib/autotest/general.m4 (AT_INIT): Adjust.
14613 2001-09-18 Paul Wagland <paul@wagland.net>
14615 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14616 correctly.
14617 Add test for AS_BASENAME.
14618 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14619 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14620 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14621 * tests/base.at: Fixed the expected responses. The old ones were
14622 one line out...
14623 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14624 the documentation claims it should (and how it behaved in 2.13).
14626 2001-09-18 Akim Demaille <akim@epita.fr>
14628 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14629 the AC_CONFIG_COMMANDS invocation.
14630 This also solves the name clash problems.
14631 Don't set the package's ID.
14632 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14633 No longer to be shipped.
14634 (version.in): Remove.
14635 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14636 * lib/autoconf/status.m4: Adjust.
14637 Use `m4_PACKAGE_STRING'.
14638 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14639 the only optional argument is the name of the test suite.
14640 Expect `package.m4' to define the package signature.
14641 * lib/autom4te.in (Autotest): Add `package.m4?'.
14642 * tests/Makefile.am (package.m4): New.
14643 * tests/suite.at: ifnames is a victim.
14645 2001-09-18 Akim Demaille <akim@epita.fr>
14647 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14648 AC_LIBSOURCE, AC_CONFIG_FILES.
14649 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14650 program version string doesn't match the package's.
14651 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14652 after `(cached)'.
14654 2001-09-17 Paul Eggert <eggert@twinsun.com>
14656 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14657 Allow expression to return any value that can fit into unsigned long
14658 (not int, as before). Check for output errors.
14660 2001-09-17 Bruno Haible <haible@ilog.fr>
14662 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14663 Always include <stdio.h> and <stdlib.h>. Evaluate
14664 the expression in an extra function before these includes. Call
14665 fprintf "%d" only after ensuring the argument is of type 'int'.
14666 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14668 2001-09-17 Paul Eggert <eggert@twinsun.com>
14670 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14671 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14672 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14673 when they don't exist.
14675 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14676 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14677 need it.
14679 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14680 version with the version used by fileutils 4.1, except use
14681 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14682 we don't need it.
14684 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14686 2001-09-13 Akim Demaille <akim@epita.fr>
14688 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14689 _first_.
14690 Reported by Gerrit P. Haase.
14692 2001-09-13 Akim Demaille <akim@epita.fr>
14694 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
14695 m4_defn'ing is valid.
14697 2001-09-13 Akim Demaille <akim@epita.fr>
14699 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
14700 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
14701 Use it.
14703 2001-09-13 Akim Demaille <akim@epita.fr>
14705 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
14706 m4_match.
14707 (m4_re_escape): New.
14708 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
14709 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
14710 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14711 Likewise.
14712 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14713 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14714 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14715 AT_tests_all for consistency.
14716 Set at_victims.
14717 (AT_VICTIMS): Similar to AT_KEYWORDS.
14718 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14720 2001-09-13 Akim Demaille <akim@epita.fr>
14722 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14724 2001-09-13 Akim Demaille <akim@epita.fr>
14726 * lib/autotest/general.m4 (AT_INIT): Create and remove
14727 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14728 test suites can cohabit.
14730 2001-09-13 Akim Demaille <akim@epita.fr>
14732 * tests/mktests.sh: Don't output banners for empty test files.
14734 2001-09-13 Akim Demaille <akim@epita.fr>
14736 Test suites can be run independently of configure.
14738 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
14739 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.
14740 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust: AC_SUBST
14741 ECHO_N etc.

14744 * lib/autotest/general.m4: Use ECHO_*.
14746 2001-09-13 Akim Demaille <akim@epita.fr>
14748 * bin/ifnames.in: Rewrite in Perl.
14749 * configure.ac: Don't look for AWK.
14750 * tests/tools.at (AWK portability): Remove.
14751 (Syntax of the shell scripts): Don't check ifnames.
14752 (AT_CHECK_PERL_SYNTAX): New.
14753 (Syntax of the Perl scripts): Check ifnames.
14754 * tests/ifnames: New.
14756 2001-09-13 Akim Demaille <akim@epita.fr>
14758 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
14759 test group titles.
14760 * tests/atspecific.m4 (AT_CHECK_AU_MACRO): AT_KEYWORDS(autoupdate).

14800 2001-09-07 Akim Demaille <akim@epita.fr>
14802 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
14803 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
14804 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
14805 related variables into `at_package_*'.

14817 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

14836 * bin/autom4te.in: --language is -l, not -s.
14838 2001-09-05 Akim Demaille <akim@epita.fr>
14840 Be ready to handle filenames as stupid as `dnl.at', for if even
14841 the maintainer is dumb enough to do that...
14843 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14844 excellence in M4 quotation: consider `__file__' is active.
14846 And BTW, when invoking m4, pass the --include in the right order:
14847 the wrong one.
14849 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14850 4m.
14852 2001-09-05 Akim Demaille <akim@epita.fr>
14854 * lib/Autom4te/XFile.pm: New lib file.
14855 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
14856 * bin/autoheader.in: Use it.
14858 2001-09-05 Akim Demaille <akim@epita.fr>
14860 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

14872 2001-09-05 Akim Demaille <akim@epita.fr>
14874 CVS GNU M4 doesn't like `undefine(undefined)'.
14876 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14877 New, extracted from main.
14878 Use IO::File wherever possible.
14879 (input.m4): Be constant, use -I instead of hard coding $tmp.
14880 Therefore be a quoted heredoc.
14881 Don't invoke `_au_disable', since ac was not loaded, but just
14882 `unm4.m4'.
14884 2001-08-31 Akim Demaille <akim@epita.fr>
14886 Version 2.52d.
14888 2001-08-31 Akim Demaille <akim@epita.fr>

14909 2001-08-31 Akim Demaille <akim@epita.fr>
14911 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14912 (testsuite Scripts): There is no such thing as `atconfig.in'.
14913 And actually one diagram is missing: test suite runtime.
14915 2001-08-31 Akim Demaille <akim@epita.fr>
14917 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14918 inverse order.
14920 2001-08-31 Akim Demaille <akim@epita.fr>
14922 * bin/autoupdate.in (@include): `installcheck' revealed the path
14923 to m4sugar was lacking!
14925 2001-08-31 Akim Demaille <akim@epita.fr>
14927 * man/Makefile.am (.x.1): We really have to pass
14928 autom4te_perllibdir.
14930 2001-08-31 Akim Demaille <akim@epita.fr>
14932 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14933 debug scripts, in particular passing explicitly listed tests to
14934 run is stupid.
14936 2001-08-31 Akim Demaille <akim@epita.fr>
14938 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14939 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14940 Use directly autom4te, not autoconf.
14941 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
14943 2001-08-31 Akim Demaille <akim@epita.fr>
14945 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

14954 * bin/autom4te.in (&parse_args): Die on unknown languages.
14955 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14956 need for autoconf.
14957 Promote --include over --macrodir and other obsolete options.
14959 2001-08-31 Akim Demaille <akim@epita.fr>
14961 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

14963 * bin/autom4te.in ($autoconf): Pass --force.
14964 `print $out' doesn't print `$_' but `$out'.
14965 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14966 (autoheader): Pass --force since the test suite goes too fast for
14967 the time stamps.
14968 Adjust to the new autoheader messages.
14970 2001-08-31 Akim Demaille <akim@epita.fr>
14972 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14973 Check the completeness of the #template.
14974 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.

14981 * bin/autoupdate.in, bin/autoheader.in: Adjust.
14982 Drop AC_MACRODIR dead for real.
14983 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14984 `autoheader: `config.hin' is created'.
14985 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14987 2001-08-31 Akim Demaille <akim@epita.fr>
14989 * bin/autoheader.in: Rewrite in Perl.
14990 * tests/autoheader: Adjust.
14992 2001-08-31 Akim Demaille <akim@epita.fr>
14994 * bin/autoconf.in (--include, -I): New option.
14995 Map --localdir, --autoconf-dir onto it.
14996 Forward autom4te's options instead of interpreting them.
14997 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14998 There is no such envvar since the inception of autom4te.cfg.
14999 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15000 * bin/autoupdate.in: Adjust, and perform more control.
15001 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15002 * tests/autoconf: Dittowise.
15004 2001-08-31 Akim Demaille <akim@epita.fr>
15006 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15007 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15008 optionally `FILE'.
15009 Use -e, not -f, since /dev/null for instance is OK.
15010 (&parse_args): Adjust.
15011 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15013 2001-08-31 Akim Demaille <akim@epita.fr>
15015 * configure.ac: Also find tested executables in bin.
15016 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
15017 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
15018 installed peer executables, only PATH is allowed to resolve it.
15019 Pass `autoconf_dir' via options, not via invisible envvars.
15020 * lib/Autom4te/General.pm (&find_peer): Remove.
15021 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15022 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15023 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15024 find the executables for it.
15025 * tests/Makefile.am: Major cleanup. Too lazy to document...
15026 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15027 We only need PERL.
15028 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15029 indeed related to running the test suite, while passing
15030 --autoconf-dir and others is related to running non installed
15031 Autoconf executables. So don't do that, leave it to...
15032 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15033 * tests/autoscan: New.
15034 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15035 refer to library files: rely on --language.
15037 2001-08-29 Akim Demaille <akim@epita.fr>
15039 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
15040 s/--set/--language/.
15042 2001-08-29 Akim Demaille <akim@epita.fr>
15044 * doc/autoconf.texi: Strip the @nodes.
15045 Suggested by Paul Eggert.
15046 (Initializing configure): Typo.
15048 2001-08-29 Akim Demaille <akim@epita.fr>
15050 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15051 Suggested by Paul Eggert.
15053 2001-08-29 Akim Demaille <akim@epita.fr>
15055 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15056 download in a tmp dir.
15058 2001-08-29 Akim Demaille <akim@epita.fr>
15060 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
15061 case insensitive OSes out there :(

15071 (&parse_args): Support --mode, --set, and --melt.
15072 * bin/autoconf.in: Simplify and adjust.
15073 * tests/Makefile.am (AUTOMAKE): Use --set.
15074 * tests/atlocal.in: Adjust.
15075 * BUGS: distcheck and check are weak.
15077 2001-08-29 Akim Demaille <akim@epita.fr>
15079 * lib/autotest/general.m4: Use
15080 foo=`(command) 2>/dev/null`
15081 not
15082 foo=`command` 2>/dev/null
15083 (at-devnull): Rename as...
15084 (AT-devnull): this.
15085 (--clean): Remove AT-* files too.
15086 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
15087 Reported by Nicolas Joly.
15089 2001-08-28 Akim Demaille <akim@epita.fr>
15091 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

15097 * doc/autoconf.texi (Function Portability): Mention C right shifts.

15121 * lib/autotest/general.m4 (AT_INIT): Log the command line.
15122 Support `VAR=VAL' as arguments.

15142 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
15143 `ac_top_builddir' to mimic Automake's vocabulary, which much more
15144 readable.
15145 Adjust callers.
15146 * doc/autoconf.texi (Configuration Actions): Document the vars
15147 available in commands.
15148 Emphasize the risks of collisions in init-cmds.

15179 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
15180 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
15181 -> ac_dir).
15182 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
15183 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
15185 2001-08-27 Akim Demaille <akim@epita.fr>

15212 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
15213 needed, 1.5 can have a macro and a target with the same name.
15214 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
15215 * m4/strip.m4: New.
15216 * m4/init.m4, m4/sanity.m4: Update.
15217 * doc/Makefile.am (CLEANFILES): 1.5 knows the texi2dvi files.

15228 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.

15230 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15231 the name of the directory they're in, instead of the filename,
15232 since version.m4 is now in m4sugar, but m4_acversion must not be
15233 classified as an Autoconf macro.
15234 ($input_m4): Don't qualify the path to m4sugar.
15235 Rather, pass autoconf_dir to m4.
15236 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

15253 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
15254 for config.status'.
15255 Open the log as soon as possible.
15256 Use the same log introduction as configure's.

15320 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
15321 * NEWS, README, README-alpha, TODO, tests/README: This package is
15322 `Autoconf', not `autoconf' (the executable).
15324 2001-08-20 Akim Demaille <akim@epita.fr>
15326 Info readers seem to need `Index' in the index node title :(
15328 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15329 simplified index node names.

15373 2001-08-20 Akim Demaille <akim@epita.fr>
15375 Huh!?!?! There are still some user EOF tags used, which prevents
15376 their use in AC_CONFIG_COMMANDS for instance...
15378 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15379 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

15442 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
15443 `$0.log' as for projects where testsuite is in src, we'd have

15458 2001-08-17 Akim Demaille <akim@epita.fr>
15460 * doc/autoconf.texi: Work around Texinfo buglets.
15461 (Transformation Rules): One example is enough, users are expected
15462 to have their brains on. And BTW, use DESTDIR.
15463 (dvar): New macro. Use it.
15465 2001-08-17 Akim Demaille <akim@epita.fr>
15467 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15473 * bin/autom4te.in: --normalize is a new option.
15474 * bin/autoconf.in: Use it.

15504 2001-08-15 Akim Demaille <akim@epita.fr>

15507 value.

15515 (cvs-dist): depends upon it.
15517 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15519 * tests/Makefile.am: Use a clean-local rule to remove
15520 autom4te.cache (it's a directory, not a file.
15521 * Makefile.am: Ditto (but maintainer-clean-local).
15523 2001-08-15 Akim Demaille <akim@epita.fr>
15525 * bin/autom4te.in (@m4_warning): New.
15526 (&handle_m4): Use it.
15527 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15528 warnings are issued at each run.
15529 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15530 is in the src tree.
15532 2001-08-15 Akim Demaille <akim@epita.fr>
15534 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15535 don't waste time running `autoupdate --version' works.
15536 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15538 2001-08-13 Akim Demaille <akim@epita.fr>
15540 * doc/autoconf.texi (ma): Rename this index as...

15591 * tests/mktests.sh: Update year in copyright notice.
15593 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15595 * tests/semantics.at (AC_C_BIGENDIAN): New test.
15597 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15599 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15600 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15601 * doc/autoconf.texi (C Compiler Characteristics): Update
15602 documentation for AC_C_BIGENDIAN.
15604 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15606 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15607 magic values from an object file when cross-compiling.
15608 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15610 2001-08-10 Akim Demaille <akim@epita.fr>
15612 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15613 effects.
15614 Suggested by Russ Allbery.
15616 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15618 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15619 current $prefix to the sub-configures.
15621 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15623 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15624 extension (needed on BeOS). Reported by Guido van Rossum.
15626 2001-08-09 Akim Demaille <akim@epita.fr>
15628 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15630 2001-08-07 Akim Demaille <akim@epita.fr>
15632 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15633 removed.
15634 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15635 No need to remove the files before and after the each test, before
15636 each test and at the end of the suite is enough.
15637 Display only the children `times', not the shell's.
15638 If the test failed or was skipped, at-times is not available.
15640 2001-08-07 Akim Demaille <akim@epita.fr>
15642 Always produce testsuite.log, including when there are no
15643 failures. This helps getting information on skipped tests, and
15644 duration of the tests. Err, implement the latter btw.
15646 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15647 Dump information on the first run of each test.
15648 (AT_CLEANUP): Create `at-times' containing the duration of the
15649 test group.
15651 2001-08-07 Akim Demaille <akim@epita.fr>
15653 The use of `dumpstat' revealed that `len' was used although it
15654 should not. m4_text_wrap was using it, but in the Autoconf world
15655 where it is legal. Hence (i) test M4sh in its own world, not
15656 Autoconf's, and (ii), ahem, fix the bug :)
15658 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15659 does not like `' instead of [].

16254 provide an alternate 'main' function name, using the 'main' from
16255 the Fortran libraries.
16256 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
16257 cross-language link tests can be performed successfully.
16258 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
16259 after $LIBS, for consistency; this should be the general rule since
