1617 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1619 <DEFAULTS>: Delay computation of variables based on $at_dir...
1620 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1621 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1622 <PARSE_ARGS>: Parse new option.

1624 * tests/autotest.at (Choosing where testsuite is run): New test

1639 * doc/autoconf.texi (Particular Programs): Do not mention the
1640 Autoconf version in which the AC_PROG_INSTALL change was done.

1643 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1645 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1646 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1647 mode, we change to the source directory, also set $ac_pwd so we
1648 do not go back to the build tree for the next config subdir.
1649 * tests/torture.at (Deep Package): Extend test to contain two
1650 config subdirs on the top level.
1652 Fix parallel `maintainer-check'.
1653 * Makefile.am (maintainer-check-tests): Depend on `all'.

1706 Fix some whitespace tests on cygwin.
1707 * tests/tools.at (autom4te and whitespace in file names): Restore
1708 font-lock. Create $TMPDIR before it might be used.

1711 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1713 Optimize AC_REQUIRE.
1714 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1715 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1716 (m4_require): Avoid extra macro calls.
1718 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1720 * tests/torture.at (srcdir): Fix quoting.
1722 Do not pass top_srcdir to configure scripts in testsuite.
1723 * tests/autotest.at (srcdir propagation): Copy install-sh to
1725 (my only test): Drop setting of `top_srcdir'.
1726 * tests/base.at (Input/Output): Likewise.
1727 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1728 config.guess, and config.sub to test source tree.
1729 Drop AC_CONFIG_AUX_DIR setting.
1730 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1731 * tests/torture.at (Substitute a 2000-byte string): Drop
1732 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1733 (Substitute a newline, datarootdir workaround): Likewise.
1734 (Define a newline): Adjust for linenumber changes in configure.ac.
1735 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1737 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1738 if `pwd` contains whitespace.

1741 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1742 * tests/tools.at (Syntax of the shell scripts): Likewise.
1744 * tests/m4sh.at (LINENO): Quote $0.
1746 Fix testsuite program wrapper for whitespace in `pwd`.
1747 The problem here is that the usual mantra is that command
1748 variables can contain arguments, thus we cannot just escape
1749 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1750 $top_builddir/tests directory early in $PATH, so that the
1751 wrappers are found by their plain name.
1752 * tests/wrapper.as: Put $testdir early in $PATH.
1753 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1755 Proper config.status --file/--header and $srcdir escaping.

1766 Quote $at_group_dir.
1767 * tests/autotest.at (whitespace in absolute testdir): New test.
1769 * lib/autom4te.in: Quote @datadir@.
1771 Proper file name escaping in Autoconf programs and Perl modules.
1772 This includes escaping of characters special to the shell
1773 as well as special to Perl, e.g., leading `<' or `>'.
1774 For example, when $file starts with `>', `open ">$file"'
1775 wrongly tries to append to a different file.
1776 * bin/autoconf.as: Fix quoting for autom4te options.
1777 * lib/Autom4te/General.pm (shell_quote): New function, taken
1778 from coreutils, written by Jim Meyering.
1780 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1782 * bin/autoreconf.in (parse_args): Likewise.
1783 * bin/autoscan.in (main): Likewise.

1786 * bin/ifnames.in: Likewise, XFile usage fixes.
1787 * tests/tools.at (autom4te and whitespace in file names): Extend
1788 test. Test twice, with special characters allowed on w32, and the
1789 rest. Test leading and trailing whitespace, for `open_quote'.
1790 (autotools and whitespace in file names): New, analogous test.
1791 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1792 by Russ Allbery and Eric Blake.
1795 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1796 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1797 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1798 (update_file, contents): Use it.
1800 * Makefile.am (autom4te-update): Rewrite for git.
1802 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1804 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1806 Fix copyright years.
1807 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1808 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1810 2007-12-04 Eric Blake <ebb9@byu.net>
1812 Manually resync with gnulib, since 'make cvs-update' no longer works.
1813 * build-aux/config.guess: New upstream version.

1816 When using older automake, don't downgrade build-aux/texinfo.tex.
1817 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1818 * doc/Makefile.am (TEXINFO_TEX): Add.
1820 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1822 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1823 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1824 #undef as this runs afoul of our new way of creating config.h.
1825 Problem reported by Jim Meyering in
1826 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1828 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1830 Fix autom4te for unusual characters in input file names.
1831 * bin/autom4te.in (files_to_options): Quote active characters
1833 * tests/tools.at (autom4te and white space in file names):
1836 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1837 Document that Tru64 awk always splits $0.
1839 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1841 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1842 `#AT_STOP_...' line at the end of each test.
1844 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1846 * lib/autotest/general.m4 (AT_INIT): For awk line number
1847 extraction script, ensure `$at_group' has a defined value
1848 even for the empty set, and properly quote its usage inside
1851 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1853 * doc/autoconf.texi (Shell Functions): New chapter. Document
1854 IRIX sh $0 issue in functions, move content from ...
1855 (Portable Shell): ... here.
1856 (Shell Script Compiler): Note that shell functions are not
1857 totally unportable any more.
1859 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1860 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1862 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1863 extracting the line numbers of the last needed test.
1865 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1867 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1870 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1872 Fix IRIX testsuite debugging failures: $0 in functions.
1873 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1874 Do not use $0 inside a function, as IRIX sh will set that to the
1875 function name rather than the script invocation name.
1877 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1878 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1880 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1881 to extract test scripts.
1882 (AT_INIT): Extract and cache test script line numbers.
1884 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1886 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1887 subsequent fixups; the awk -> here-document conversion trashes
1888 performance too much with AIX sh.
1890 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1892 * tests/local.at: Do not test m4, perl with AT_TESTED.
1894 Diagnose and guard against write errors dealing with config.status.
1895 The general idea is this: all write failures from `configure'
1896 writing `config.status' are indicated by $ac_write_error, which
1897 is only checked at the end. This is safe because config.status
1898 code is not executed before the file is complete. Other write
1899 failures, be they inside config.status, or in sub shell/awk
1900 scripts spawned from configure or config.status, typically need
1901 earlier checking, as their results are used right afterwards.
1902 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1903 before writing config.status, check afterwards.
1904 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1905 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1906 Set `ac_write_error' for write failures to config.status. Barf
1907 upon write failures to temporary files.
1908 Adjust note about closing and reopening the here-document.
1909 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1910 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1911 reopening the here-document.
1912 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1913 Ensure `ac_write_error' does not escape into config.status.
1914 Also, add a couple of code paths not yet exercised in the test
1915 suite: a config file with input from stdin, and a config header
1917 Suggestion for catching write errors by Bruno Haible.
1919 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1921 Avoid error with Tru64 awk and testsuite lines with many words.
1922 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1923 reads the testsuite, set the field separator to an unusual value,
1924 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1925 even splits the input if $i, i>0, was never accessed in the script.
1927 Revert 2007-10-17 change.
1928 * TODO: Multiline args in config files and headers mean something
1929 different and are not fixed, see
1930 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1931 Report by Stepan Kasal.

1935 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1937 AC_*_TOOL does not canonicalize the prefix
1938 * doc/autoconf.texi (Generic Programs): Do not say that
1939 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1941 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1943 Diagnose write errors in config.status instantiations.
1944 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

1947 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1991 Clean up the rule to create "expr".
1992 * tests/Makefile.am (expr): Don't redirect directly to target.

2002 These no longer check for preprocessor flaws.
2003 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2004 Do not check for preprocessor flaws.
2006 2007-11-13 Jim Meyering <meyering@redhat.com>
2008 Adapt dependencies, now that a version change doesn't modify configure.ac
2009 * GNUmakefile: Remove "make clean" kludge.

2033 Add -v option to autoreconf invocation.
2035 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2036 * GNUmakefile (dummy): Remove INSTALL.
2038 Remove racy commands to build scripts in bin/ and tests/.
2039 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2040 are guaranteed to be built, remove the rules that tried to build
2041 them. Before, with a parallel build, these rules could lead to
2042 two processes writing tests/wrapper.in concurrently.
2044 Build in man/ only *after* building in bin/ and tests/.
2045 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2046 in both bin/ and tests/.
2048 Accommodate non-srcdir build-from-checkout.
2049 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2050 Use git's --git-dir=$srcdir/.git option.
2051 Add quotes, in case tarball_version_file contains shell meta-characters.
2052 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2053 * configure.ac: Pass "." to git-version-gen.
2055 Avoid spurious test failures due to version skew.
2056 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2058 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2060 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2061 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2062 Remove conftest.dSYM directory.
2063 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2064 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2065 Remove `conftest.*' recursively.
2066 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.

2073 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2075 Fix typos in variable names.
2076 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2078 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2080 Document that $((expression)) is not portable.
2081 * doc/autoconf.texi (Shell Substitutions): Here.
2083 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2085 Ignore configure --help* errors due to LINENO-impaired shells.
2086 * tests/torture.at (Configuring subdirectories, Deep Package):
2087 In the --help* tests in read-only trees, make `.' temporarily
2088 writable again for the `stderr' file, and ignore errors due to
2089 the attempt to write configure.lineno.
2090 Report by Patrick Welche.
2092 2007-11-10 Jim Meyering <meyering@redhat.com>
2094 Generate package.m4 in build-dir, not srcdir.
2095 * tests/Makefile.am (package.m4): Adjust target.
2096 Don't redirect directly to $@.
2097 (CLEANFILES): Add package.m4.
2098 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2100 When running $(AUTOTEST), search "." before searching $(srcdir).
2102 Avoid a race condition that would make parallel "distclean" fail.
2103 * tests/Makefile.am (distclean-generic): Replace the default,
2104 automake-provided rule with an identical one, but with an additional
2105 dependency on distclean-local. Simply adding the dependency would
2106 cause automake not to emit the rule at all.
2107 * BUGS: Building with -jN works, now.
2109 Distribute git-version-gen.
2110 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2111 since GNUmakefile is distributed, and requires it for dist* rules.
2113 Remove two more generated files from version control.
2114 * INSTALL: Remove generated file.
2115 * lib/autoscan/autoscan.list: Remove generated file.
2117 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2119 * GNUmakefile (PATH): Remove stray apostrophes; they become
2120 part of PATH, which isn't wanted here.
2122 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2124 New config files output variable `top_build_prefix'.
2125 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2127 * doc/autoconf.texi (Preset Output Variables): Document it.
2129 Report by Bob Friesenhahn.
2131 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2132 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2133 function, to parametrize arithmetic with expr vs. the shell.
2134 Use it where possible.
2135 Suggestion by Benoit Sigoure.
2137 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2139 Adjust the documentation of autotest WRT atlocal.
2140 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2141 when using Automake, to write a rule to produce atlocal, since it's
2142 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2143 distributed, not atconfig.in.
2145 2007-11-04 Eric Blake <ebb9@byu.net>
2147 Update list information.
2148 * README: Mention new autoconf-commit list.

2151 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2153 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2155 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2157 * build-aux/.gitignore: Ignore mkinstalldirs.
2159 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2161 2007-11-03 Jim Meyering <meyering@redhat.com>
2163 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2164 * build-aux/git-version-gen: This syncs from coreutils.
2166 Adjust the build procedure so "make check" works reliably.
2167 * README-hacking: Include an extra step between "make" and
2168 "make check" to ensure that the latter passes.
2170 Use just-built tools, when possible.
2171 * GNUmakefile (PATH): Set and export here, ...
2172 (dummy): ... rather than here.
2174 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2175 and Andreas Schwab <schwab@suse.de>
2177 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2180 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2182 * configure.ac (AC_PREREQ): Require version 2.60, for
2183 AC_PROG_SED, AC_PROG_GREP.
2185 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>

2190 Document a bug in GNU Bash with compound commands and redirections.
2191 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2192 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2195 2007-11-03 Eric Blake <ebb9@byu.net>
2197 Support m4 1.4.5 in testsuite.
2198 * tests/torture.at (Define a newline): Exclude line numbers in
2200 Reported by Ralf Wildenhues.
2202 2007-11-03 Jim Meyering <meyering@redhat.com>
2204 Remove automake-provided files from version control.
2205 * build-aux/elisp-comp: Remove file.
2206 * build-aux/install-sh: Remove file.
2207 * build-aux/missing: Remove file.
2208 * build-aux/mdate-sh: Remove file.
2209 * build-aux/.gitignore: New file.
2210 Suggestion from Ralf Wildenhues.
2212 2007-11-03 Eric Blake <ebb9@byu.net>
2214 Adjust version comparison to account for git snapshot numbers.
2215 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

2221 2007-10-30 Bruno Haible <bruno@clisp.org>
2223 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2224 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2225 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2226 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2227 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2228 Suggested by Paul Eggert.
2230 2007-10-28 Jim Meyering <meyering@redhat.com>
2232 * README-hacking: Autoconf, Automake, and Perl are required to build.
2233 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2235 2007-10-28 Jim Meyering <meyering@redhat.com>
2237 README-hacking: Recommend running autoreconf -vi.
2238 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2239 so that we use just-built tools when they're available.
2240 Suggestions from Ralf Wildenhues.
2242 2007-10-28 Jim Meyering <meyering@redhat.com>
2244 Make inter-release --version output more useful.
2246 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2247 which indicates that it is built using the 19th change set
2248 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2249 is a prefix of the commit SHA1.
2250 * build-aux/git-version-gen: New file.
2251 * configure.ac: Run it to set the version.
2252 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2253 * Makefile.am (dist-hook): Arrange so that .version appears only
2254 in distribution tarballs, never in a checked-out repository.
2255 * .gitignore: Add .version here, too. Just in case.
2256 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2257 not configure.ac, now that the version number changes automatically.
2259 Ensure that $(VERSION) is up to date for dist-related targets.
2260 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2261 git-version-gen doesn't match $(VERSION), but only for dist targets.
2263 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2265 Fix `Deep Package' failure with a configure script early in PATH
2266 * tests/torture.at (Deep Package): Add `.' early in PATH.

2291 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2292 and Eric Blake <ebb9@byu.net>
2294 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
2295 problem reported by Bruno Haible in
2296 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2298 2007-10-22 Eric Blake <ebb9@byu.net>
2300 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2303 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2305 Don't check for bug in HP-UX 11.00 cpp.
2306 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2307 Use -1ull rather than -1u, since that causes problems with gnulib; see
2308 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

2326 escaping of backslash in here-documents.
2328 Fix `Deep Package' test failure on FreeBSD.
2329 * tests/torture.at (Deep Package): Do not add `.' to $PATH
2330 unnecessarily. Do not try running `/bin/sh configure' with a
2331 configure script to be found in $PATH, if the shell does not do
2332 this resolution. Fixes test failure on FreeBSD.
2334 Fix config header generation with AIX awk.
2335 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2336 script, use helper array D_is_set, as `" 0"' does not evaluate
2337 to true for AIX awk.
2339 2007-10-21 Eric Blake <ebb9@byu.net>

2374 * lib/autotest/general.m4 (BANNERS): New named diversion.
2375 (TESTS_END): Diversion no longer used.
2376 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
2377 shell function, which prints only as needed, using an associative
2378 array of banner text from a special diversion.
2379 <PARSE_ARGS_END>: No longer need awk to find banners.
2380 <TESTS>: Banners are no longer processed by main driver loop, so
2381 we no longer need case statement.
2382 (AT_BANNER): Rewrite to populate new diversion.
2383 (AT_SETUP): Each test invokes its own banner. No output is needed
2384 to the TESTS diversion.

2410 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Fix
2411 duplication bug by using new macro.
2412 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
2413 programs with stdin redirected, so programs that don't
2414 understand --version won't try to behave interactively.
2415 * tests/autotest.at (Tested programs): Catch this bug.
2416 * tests/m4sugar.at (m4@&t@_append): Test new macro.

2476 is not writable, use 'cp -p' in this case, in the hope that it
2477 will not actually be needed. Still try removing files, in case
2478 of other write errors.
2479 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
2480 use $as_myself, not $0.
2481 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
2482 exist, try again in the the source tree. This change assumes
2483 that the subpackage configure script is capable of running
2484 --help=recursive in the source tree.

2507 (m4_echo, m4_make_list): New documented macros.
2508 (_m4_quote, _m4_shift2): New helper macros.

3518 for a.* when searching for executables, as this prevents users
3519 from having files like a.c. Problem reported by Ralf Wildenhues in:
3520 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3521 This fixes a problem introduced on 2000-12-19.

3525 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
3526 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
3529 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
3531 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3532 AC_CHECK_TYPE, AC_CHECK_TYPES.
3533 * doc/autoconf.texi (Generic types): C types must be type-names
3534 (the C terminology), not type-ids (the C++ term). C++ types
3535 must not be anonymous.
3536 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3537 for C++; this drops support for anonymous struct and union types,
3538 which were problematic anyway.
3539 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3542 2007-04-12 Jim Meyering <jim@meyering.net>
3544 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

3554 * doc/autoconf.texi (Generic Types): Document the restrictions
3555 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3556 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3557 with objects too. Document the restrictions on its use.
3558 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3559 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3560 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3561 works but the latter doesn't, then it's a valid type.
3562 This lets people use function types and so forth.
3563 For C++ there doesn't seem to be a simple solution, so leave it alone.
3564 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3565 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3566 AC_CHECK_TYPE; that wasn't documented or necessary.
3568 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3570 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
3571 when cross-compiling.

3591 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
3592 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
3593 default still has the problem. Problem reported by Bruce Korb.

3614 checks for unsigned long long int.
3616 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3618 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3619 nonstandard grep R.E. escape sequences.
3621 2007-03-17 Jim Meyering <jim@meyering.net>
3623 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3624 (Limitations of Usual Tools): Also list \< and \>, and mention that
3625 HP-UX's grep, like the one from Solaris, does not support that syntax.
3627 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3629 * doc/autoconf.texi (Specifying Names): `--host' does not
3630 change the build type.
3632 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3634 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3635 suggests AC_CONFIG_HEADERS.

3646 universal binaries. Problem reported by Elias Pipping.
3648 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3650 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3651 * doc/autoconf.texi (C Compiler): Document this. There is a new
3652 extra argument ACTION-IF-UNIVERSAL.
3653 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3654 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3655 Reindent for sanity's sake.
3657 2007-02-24 Eric Blake <ebb9@byu.net>

3667 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3668 status of rm so we know when it failed.
3669 If cleaning of test dir failed before running the test, warn.
3670 Output the line separator in verbose mode before the warning
3671 to make clear the warning belongs to the following test.

3698 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3699 input from /dev/null in awk test, so even Solaris /usr/bin/awk

3736 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3737 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3738 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3739 substitution will still be done by the special code.

3761 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3763 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3764 early on the reader side, drop stderr of the input to avoid
3765 `broken pipe' error output; this may happen even with shell
3766 builtin `echo' of some bash versions. Reports by Ian Macdonald
3767 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3769 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3782 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3783 * doc/autoconf.texi (Signed Overflow Examples): Give more
3784 discussion about the allow_superuser_privileges example,
3785 and change it a bit to make things clearer.
3786 (Optimization and Wraparound): Clarify whether the compiler
3787 will generate an infinite loop for the example derived from
3788 Autoconf's mktime test.
3789 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3790 Also, clarify unsigned multiplication overflow.
3792 2007-01-04 Eric Blake <ebb9@byu.net>
3794 * bin/Makefile.am (RELEASE_YEAR): New macro.
3795 (edit): Use it to supply correct copyright year to scripts.
3796 * bin/autoconf.as (version): Use it.
3797 * bin/autoheader.in ($version): Likewise.
3798 * bin/autom4te.in ($version): Likewise.
3799 * bin/autoreconf.in ($version): Likewise.
3800 * bin/autoscan.in ($version): Likewise.

3804 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3806 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3807 feedback. The most important changes document what happens when
3808 you convert an out-of-range value to a signed integer type, and
3809 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3812 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3813 rewrite, taking notions from the recent discussion on the gcc and
3814 autoconf mailing lists; please see
3815 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3816 and follow the many links.
3817 (Integer Overflow Basics, Signed Overflow Examples):

3819 (Signed Integer Division): New sections.
3821 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3823 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3824 preprocessor macro arguments in traced name.
3825 * doc/autoconf.texi (Defining symbols): Document longstanding
3826 support for AC_DEFINE-ing macros with arguments, and document
3827 behavior when the same variable has multiple AC_DEFINEs.
3828 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3829 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3830 macros directly, giving much shorter and simpler code.
3832 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3834 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3835 space before "$ac_configure_args" to prevent a 'config.status
3836 --recheck' failure if ac_configure_args doesn't contain a leading
3837 space. This works around a problem with the XEmacs configure.ac,
3838 which uses the (undocumented) ac_configure_args variable
3839 inconsistently with Autoconf.
3841 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3843 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3844 Include <limits.h>, and use its INT_MAX to rewrite the
3845 j loop so that it does not overflow 'int'. Problem reported by
3847 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3848 Play it safe by shifting left by 1 rather than multiplying by 2,
3849 as GCC is less likely to optimize this away when the value
3850 is signed (when it assumes overflow leads to undefined behavior).
3851 Also, don't assume time_t uses two's complement.
3853 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3855 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3856 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3857 dumps core on it. Report by Tim Rice.
3859 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3861 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3862 --disable-option-checking to --help output even when
3863 AC_PRESERVE_HELP_ORDER is not used.
3864 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3865 --with argument, rather than argument with [-.] replaced by
3867 * NEWS: Fix typo in previous change; the news was in the
3870 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3872 * NEWS: Warnings are now generated by default for unknown
3873 --enable-* and --with-* options.
3874 * doc/autoconf.texi (Option Checking): Renamed from
3875 (Configure Option Checking). Tighten up the wording a bit.
3876 (External Software, Package Options): Cross-reference to Option
3877 Checking, and use this to shorten our section.
3878 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3879 "$x" to test "x$foo" != x.
3880 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3881 Don't warn if $enable_option_checking is "no".
3882 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3883 ac_unrecognized_opts to the empty string.
3884 Don't echo the unrecognized opts, as this might mishandle
3885 backslashes or leading -.

3887 usage next to the other --disable-FEATURE options in the

3892 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3893 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3894 Print warning for unrecognized --with and --enable options
3895 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3896 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3897 Disable option checking when subdirs are configured.
3898 (AC_OUTPUT): If warnings are enabled, print warning about
3899 unrecognized --with and --enable options at the end of
3900 the configure output (as well as at the beginning).
3901 * doc/autoconf.texi (Option Checking): New node.
3902 Document new option warning functionality.
3904 2006-12-16 Eric Blake <ebb9@byu.net>
3906 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3907 * NEWS: Start news for current version.
3909 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3911 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3912 Define HAVE_GETMNTENT to 1, not to the empty string.
3913 Problem originally reported by Jochen Friedrich in
3914 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3916 This change prompted by a problem report by Andrey Simonenko in
3917 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3918 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3919 object-like macros only, in the traditional portable character
3921 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3922 Warn about attempts to define things that are not identifiers.
3923 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3924 awful hack that AC_DEFINEd macro names containing parentheses.
3926 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3928 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3929 too drastic, even if Texinfo in theory requires it for info mode.
3931 (config.status Invocation): Renamed back from Recreating a
3933 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3934 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3936 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3938 * NEWS: Version 2.61a.
3940 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3941 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3943 * NEWS: Document changes with echo and printf, and the lack
3944 of limits on the total size of multi-line values of substituted
3945 variables, and the AC_FUNC_FSEEKO fix.
3947 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3949 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3950 Writing configure.ac.
3951 (Autoconf Input Layout): Renamed from configure.ac Layout.
3952 (Recreating a Configuration): Renamed from config.status Invocation.
3953 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3954 (acconfig Header): Renamed from acconfig.h.
3955 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3956 (Writing Testsuites): Renamed from Writing testsuite.at.
3957 (Autom4te Cache): Renamed from autom4te.cache.
3959 * BUGS: Remove mention of VPATH problem, since it's now documented
3960 not to be a bug in the Autoconf build procedure itself, but rather
3961 a problem with the proprietary `make' programs.
3963 * doc/autoconf.texi (Build Directories): Add a cross reference
3966 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3967 * doc/standards.texi: Sync from gnulib.

3972 generated automatically.
3974 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3976 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3977 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3978 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3980 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3982 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3983 `CEOF$ac_eof' special marker, the awk script cannot contain a
3984 line matching `^CEOF', so this is not needed any more.
3985 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3986 special marker in the test.
3988 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3990 * tests/tools.at (autom4te preselections): Use `find -newer';
3991 remove one of the sleeps.
3993 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3994 more readable, using ...
3995 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3997 * doc/autoconf.texi (autoheader Invocation): Do not double-
3998 quote the parameter of `AH_BOTTOM' in the example.
4000 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4002 * doc/autoconf.texi (Configuration Headers): Remove the
4003 example with multiple input files.
4004 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4005 multiple input files.
4007 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4009 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4010 creating the awk substitution script, handle one input line at a
4011 time, so that the maximum length of a substituted (multi-line)
4012 value is not limited by the size of the sed pattern space.
4013 The trade-off is a slightly repetitive sed script.
4014 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4015 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4016 * tests/torture.at (Substitute a 2000-byte string): Increase the
4017 test with several long lines, they should not be caught by sed
4020 * tests/tools.at (autom4te preselections): New test, to flag
4021 entries missing from autom4te.cfg.
4022 Report by David Byron <dbyron@hheld.com>.
4024 * tests/torture.at (Substitute a 2000-byte string): Actually use
4025 AC_PROG_AWK, so the last change works as intended.
4026 (Substitute and define special characters): Likewise.
4027 (Substitute a newline): Likewise.
4029 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4030 instead of `awk' consistently.
4031 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4032 * tests/torture.at (Torturing config.status): Test both the
4033 result of AC_PROG_AWK and plain awk.
4034 (Substitute a 2000-byte string): Likewise.
4035 (Substitute and define special characters): Likewise.
4036 (Substitute a newline): Likewise.
4038 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4040 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4041 can be assigned to a function pointer. Problem reported by
4042 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4043 part of a patch by Ralf Wildenhues in that same bug report.
4045 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4047 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4048 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4050 2006-12-01 Eric Blake <ebb9@byu.net>
4052 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4053 cross-compiling from cygwin to mingw.
4054 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4055 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4056 to lib/autoconf/c.m4.
4058 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4060 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4061 string for more reliable failure. Wrap the entire test that
4062 causes the broken Solaris printf to dump core, in a subshell,
4063 so the segmentation fault message is reliably suppressed.
4064 Fix shell expansion errors by using /usr/ucb/echo always;
4065 avoid an error on systems without it by another subshell.
4066 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4067 subshell-$as_echo to `as_echo', for better error message.
4069 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4071 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4072 `BASH_SOURCE' contain a newline, set them to empty, as they may
4075 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4077 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4078 years and is too hard to maintain now. The last straw was
4079 reported by Jerker Baeck in
4080 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4081 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4082 * doc/autoconf.texi (Particular Functions): Move
4083 AC_FUNC_SETVBUF_REVERSED from here...
4084 (Obsolete Macros): ... to here. Say that it does nothing now.
4085 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4086 Turn into (almost) a no-op.
4088 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4090 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4091 These macros are obsolescent and new applications shouldn't need them.
4092 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):

4098 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4099 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4101 * doc/autoconf.texi (Setting Output Variables): Mention that
4102 @VAR1@VAR2 has unspecified behavior. Problem reported by
4104 * NEWS: Mention this.
4106 * Makefile.am: Put only a single '#' into the copyright notice,
4107 so that it's also present in the output file. Standardize wording
4108 in makefile copyright notices to match GNU coding standards.
4109 * bin/Makefile.am: Likewise.

4122 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4124 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4125 in the sed script that mangles the awk script: delete up to the
4126 first exclamation mark only.
4127 * tests/torture.at (Substitute and define special characters):
4130 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4132 Rewrite config files generation: avoid quadratic growth in
4133 the number of substituted variables by using awk instead of sed
4134 for the bulk of the substitutions.
4135 * NEWS: Mention this.
4136 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4137 forbidden in the output (and thus input) file.
4138 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4139 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4140 generate just one large awk script for substitutions,
4141 eliminating much of the earlier complexity, while adding some
4142 new complexity. Only expand the substitution templates at
4143 configure time, for smaller configure script size. If
4144 _AC_SUBST_FILES are used, test 'awk' for working getline support
4145 at config.status time. If absent, interpolate through the
4146 shell. The awk script was written with much help
4147 from Paolo Bonzini and Paul Eggert.
4148 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4149 (_AC_SED_FRAG_NUM): Likewise.
4150 (_AC_SUBST_CMDS): Renamed from...
4151 (_AC_SED_CMDS): ...this.
4152 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4153 * tests/torture.at (Substitute a 2000-byte string): Also
4154 substitute a line with 1000 words, and a variable with several
4156 (Substitute and define special characters): Test awk special
4157 characters, and put substitution input strings `@foo@' in the
4158 output, to test that no recursion happens; test several other
4159 combinations from Paolo Bonzini.
4161 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4163 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4164 that replaced echo with AS_ECHO where this wasn't necessary.
4165 Problem reportd by Ralf Wildenhues.
4166 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4167 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4168 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4170 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4172 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4174 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4176 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4177 that traditional Awk lacks 3-arg "split". It has it.
4178 Mention that FS must be a single character, and a few other
4179 99-byte limits of traditional Awk.
4180 Mention that if (i in a) doesn't work with traditional Awk.
4182 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4184 * tests/autotest.at (BSx641-newline in command):

4186 (Newline-CODE-BS-newline in command):
4187 (Single-quote-BS-newline in command):
4188 (Single-quote-newline-BS-newline in command):
4189 Use printf '%s\n' instead of echo, for portability to hosts
4190 where echo interprets backslashes. This will break on hosts
4191 that lack printf, but for now let's assume all such hosts
4192 are dead (if not, we should get reports of test failures).
4194 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4196 'echo' has some portability problems, when given a first argument
4197 with a leading '-', or when given any argument containing '\'.
4198 Avoid using 'echo' in these cases.
4199 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

4227 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4228 Don't use ECHO_T, since ECHO_N is now reliable.
4229 * lib/autotest/general.m4 (AT_INIT): Likewise.
4230 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4231 rather than using a here-document to put the script into a file.
4232 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4234 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4235 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4236 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4237 bug, but we might as well stop using ECHO_N and ECHO_C internally.

4240 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

4242 operand, as AS_ECHO requires. Avoid double file name expansion.
4243 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4244 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4245 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4246 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4247 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4248 Double-quote strings that would otherwise contain M4 comments.

4251 * configure.ac (AC_INIT): Bump to 2.61a.
4254 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4258 * configure.ac (AC_INIT): Bump to 2.61.
4261 * tests/autotest.at (Macro with backslash in a test title):
4262 Comment out for now, as this tests neither fails nor passes
4263 reliably. Problem reported by Ralf Wildenhues.

4280 Import these changes from config via gnulib:
4282 2006-11-15 Ben Elliston <bje@gnu.org>
4284 From Josselin Mouette <joss@debian.org>:

4355 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4356 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4357 Imported from a similar patch to gnulib by Bruno Haible.
4359 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4361 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4378 and Stepan Kasal <kasal@ucw.cz>
4380 Handle special characters in test case titles correctly.
4381 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4383 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4384 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4385 argument. Extend to check titles printed by ./micro-suite and
4386 ./micro-suite -l and the title in micro-suite.log.
4387 (Backquote in a test title,
4388 Single-quote in a test title,
4389 Double-quote in a test title): Don't expect failure anymore.
4390 (Backslash in a test title): Put a non-whitespace character after the
4391 backslash so that Bourne shells might actually see it as an escape
4393 (Brackets in a test title,
4394 Pound in a test title,
4395 Comma in a test title,

4402 * tests/torture.at (#define header templates): M4-quote this title in
4403 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4404 The visible effect was a stray [] in the testsuite output.
4406 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4408 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

4411 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4413 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4414 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4415 5363) simply issues a warning when dividing by zero at compile
4416 time. Problem reported by Elias Pipping.
4418 2006-10-26 Eric Blake <ebb9@byu.net>
4421 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4422 show effect on macros that expand with commas.

4449 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4450 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4451 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4452 reported by Nelson H. F. Beebe for Coreutils 6.4.
4454 * tests/tools.at (autoconf --trace: user macros): Remove test
4455 for tracing multiline macros, since m4 1.4.7a uses a different
4456 way to number lines. Problem reported by Ralf Wildenhues.

4534 (Imported from Automake.)
4535 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4536 which incorrectly sets the mode of an existing destination
4537 directory. In some cases the unpatched install-sh could do the
4538 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4539 system. We hope this is rare in practice, but it's clearly worth
4540 fixing. Problem reported by Alex Unleashed in
4541 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4542 Also, don't bother to check for -m bugs unless we're using -m;

4592 added to the template can get mangled.
4594 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4596 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4597 include the default headers, and redefine obstack_chunk_alloc
4598 and obstack_chunk_free. Fixes false failure with glibc.

4615 the NonStop platform.
4616 * doc/autoconf.texi (Posix Variants): Likewise.
4617 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4619 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4620 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4621 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4622 Use a better substitute, by inspecting the output of "ls"
4623 rather than just using ":".
4624 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4625 rather than AS_EXECUTABLE_P, since we needn't worry about
4626 non-regular files here.
4628 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4629 due to configuration hassles with this. See Tonya Underwood's report

4642 initialization which is not inherited through the environment
4643 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

4649 problems with mkdir -p -m.
4651 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4653 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4654 comment about ac_cpp_err; it was incorrect, and anyway
4655 ac_cpp_err is being removed below.
4656 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4657 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4658 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4660 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4661 with werror_flag and conftest.err and so forth. This is more
4662 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4663 and anyway the user shouldn't normally want to see this gorp logged.
4664 Problem reported by Ralf Wildenhues.
4665 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4666 empty, not 'no', since the rest of the code uses 'test -z'.
4668 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4670 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4671 Use a single call to AC_DO_TOKENS rather than multiple, for
4673 (_AC_LINK_IFELSE): Test that resulting file is executable.
4674 Problem reported by mwoehlke in
4675 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4677 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4678 than creating a file to use with test -x; this is much faster.
4680 2006-10-02 Bruno Haible <bruno@clisp.org>
4682 * lib/autom4te.in (Automake-preselections): Add
4683 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4685 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4687 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4688 standard error, `experr' should be used, not `expout'.

4692 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4693 fseeko testing program twice; just use the earlier result.
4694 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4695 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4696 still doesn't let the program compile.
4697 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4700 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4701 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4702 include it, without including anything else.
4703 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4705 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

4710 `error.h', and include it, for a `error_at_line' prototype.
4711 Use a nonempty format string in the link test.
4712 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4713 for a declaration of wait3.

4719 can apply to constants too, and that it checks for macro defns.
4720 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

4722 values. Problem reported by Ralf Wildenhues.

4884 except the first two arguments are reversed.

4935 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4936 didn't work if some values were cached but not others. Test for
4937 broken lex libraries like native ia64-hp-hpux11.22; see
4938 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4939 work around the problem by preferring an empty LEXLIB to -lfl or
4940 -ll. Let the user set LEXLIB='' to indicate no library needed.

5067 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
5068 -Wundef -Werror". Problem reported by David Fang in
5069 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

5091 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
5092 problems with arg script text that doesn't end in newline, and

5129 less skeptical about "volatile", after discussion with
5130 Bruno Haible on bug-gnulib.

5141 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5142 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5144 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5146 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5147 after -R regardless of host. Patrick Welche reports that this
5148 fixes things on NetBSD 3.99.

5158 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5159 under AC_C_VOLATILE.
5160 (Volatile Objects): Be a little less skeptical about what
5161 "volatile" means. Derived from thoughts by Ben Pfaff in
5162 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5164 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5168 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5170 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5171 more globally, since the 2006-06-30 patch didn't suffice. Problem
5172 reported by Keith Marshall. Also, don't bother with builddir2,
5173 since it shouldn't be needed any more.
5175 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5177 * doc/autoconf.texi (Generic compiler characteristics):
5178 Document AC_COMPUTE_INT. Fix wrong statements on Default
5179 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

5192 * NEWS: Document previous change.
5194 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5196 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5197 Require that long long int be at least 64 bits wide. C99 requires
5198 this and enough programs depend on it so we should check for it.
5199 Bruno Haible reports in
5200 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5201 that long long int is 32 bits wide with some nonstandard compilers.
5202 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.

5206 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5207 to a nonexistent file, so that we don't have to worry about
5208 a local site configuration that doesn't use /usr/local.
5209 Problem reported by Keith Marshall in
5210 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5212 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5214 * doc/autoconf.texi: Be more consistent about using @acronym with
5215 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5216 quite right (it talked about "OSF/Tru64", even though the
5217 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5218 and it even mentioned "OSF 4"!) and at this point there's little
5219 reason to talk about OSF any more, since it died in 1994.
5220 (Specific Compiler Characteristics): Simplify example of
5221 negative-size array.
5222 (File Descriptors): Reorder to make the text flow better.
5223 Remove joke about "appreciate the various levels"; I didn't get it.
5224 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5225 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5226 (File Descriptors, Limitations of Usual Tools):
5227 Tone down the advice against renaming or removing open files.
5228 (Limitations of Usual Tools): Add a new section, on 'rm'.
5230 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5232 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5233 -lXt in LIBS, idea from Karsten Hopp; this was due since
5236 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5237 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5238 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5239 (which belong to Xt, not X itself). See Debian bug 327655.
5241 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5243 * configure.ac (AC_INIT): Bump to 2.60a.
5246 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5250 * configure.ac, NEWS: Update.

5257 quadrigraph correctly in traces.
5259 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5262 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5263 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5265 * doc/autoconf.texi (Changed Directory Variables): New node,
5266 to document the whole `datarootdir' business a bit better.
5268 * tests/torture.at (datarootdir workaround): Extend test.
5269 Prompted by report by Alexandre Julliard.
5271 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5273 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5274 when using default mode of IBM C 6 for AIX. Problem and two-line
5275 fix reported by Larry Jones.
5277 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5279 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5280 about literal '${datarootdir}' if a definition is found in the
5283 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5285 * NEWS: Use "M4" rather than "m4" when appropriate.
5286 Problem reported by Eric Blake.
5287 * doc/autoconf.texi: Likewise.
5288 Use @acronym around BSD, GCC, and GNU when appropriate.
5289 (Why GNU M4): Renamed from "Why GNU m4".
5290 (Redefined M4 Macros): Mention that Posix
5291 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5292 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5295 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5297 * bin/autom4te.in (handle_output): Do not forbid the empty
5299 * tests/tools.at (autoconf: the empty token): New test.
5301 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5303 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5304 calls, so that we do not care whether they are LIFO or FIFO;
5305 in the m4_wrap, do not check which diversion is the topmost
5306 one, just check that the stack is balanced at the end.
5307 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5308 base diversion forever--pop the previous diversion before
5309 opening the new one; consequently, remove the m4_wrap call.
5310 * lib/autotest/general.m4 (AT_INIT): Likewise.
5311 * tests/m4sugar.at: Do not use
5312 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5314 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5315 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5317 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5318 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5319 Rework example of m4wrap token-pasting trouble so that it doesn't
5320 care whether it's LIFO or FIFO.
5321 Fix some "contrary to"s that are awkward in English.
5323 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5325 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5326 to `yes' instead of `int$1_t' if the type is found, for more
5327 consistent configure output (where $1 is the number of bits).
5328 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5329 Suggested by Bruno Haible.
5331 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5332 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5333 with system headers. Report by Bruno Haible.
5335 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5337 * config/config.guess, config/config.sub: Sync from upstream.
5339 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5340 in order to avoid picking up an older installed frozen m4sh.m4f.
5341 Besides an outdated shell startup, this could have been created
5342 by an earlier M4 version with incompatible frozen file format.
5344 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5346 * README: Recommend m4 1.4.4 instead of 1.4.3..
5347 * doc/autoconf.texi: Likewise.
5348 (Special Chars in Names): Say that $(.FOO) is portable, as
5349 suggested by Stepan Kasal.
5350 (Installation Directory Variables, Build Directories):
5351 (Automatic Remaking, Subdirectories, Fortran Compiler):
5352 (Making testsuite Scripts, Defining Directories):
5353 Quote variable usages better.
5354 (Making testsuite Scripts): Add clean-local rule to makefile
5355 snippet, by Eric Blake.
5356 (Installation Directory Variables): Fix table item font.
5357 Reword slightly to clarify. Generalize advice about
5358 not using special characters to include all file-related
5359 vars, not just VPATH.
5360 (Special Chars in Variables): Warn about special characters in
5362 (Assignments): Clarify default-value example as suggested by
5364 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5365 (Special Shell Variables): Note leading ./ or ../, as suggested
5367 (Limitations of Builtins): Under cd, warn about CDPATH.
5368 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5371 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5373 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5374 `@var', for texi2html.
5375 (Systemology): Some more word wrapping, for DVI output.
5376 (autom4te Invocation): The short option for `--melt' is `-M',
5379 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5381 * doc/autoconf.texi: More formatting and English tweaks,
5382 many suggested by Ralf Wildenhues.
5383 Reword to avoid "@code{...}'s" and the like, since it's ugly
5384 with Emacs info mode. discontents -> woes.
5385 Put a few "will"s back. time stamp -> timestamp.
5386 side-effect -> side effect.
5388 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5390 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5391 Warn about $@ not persisting. Problem reported by Julien Danjou in
5392 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5393 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5394 Mention other special chars, too.
5396 2006-06-14 Eric Blake <ebb9@byu.net>
5398 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5400 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5402 * doc/autoconf.texi: Some systematic minor improvements, as
5403 follows. Use "makefile" when talking about makefiles
5404 generally (which might be named "makefile" or "Makefile" or even
5405 "foo.mk"), "Makefile" when talking about a specific makefile
5406 called "Makefile". This unclutters the text from weird quotes
5407 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5408 values" rather than "@var{foo}s" and similar constructs containing
5409 "}s". Use "Make rules" rather than "Makefile rules". Minor
5410 English-language improvements. Change the prefix "sub-" to "sub"
5412 Put blank lines around examples more consistently.
5413 Avoid "rather" and "very" as intensifiers.
5414 Avoid "will" as an auxiliary.
5415 (Limitations of Make): Split this node into....
5416 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5417 (Leading _ in Macro Names, Backslash-Newline-Newline):
5418 (Backslash-Newline Comments, Long Lines in Makefiles):
5419 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5420 (obj/ and Make, make -k Status, VPATH and Make):
5421 (VPATH and Double-colon, $< in Explicit Rules):
5422 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5423 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5424 New nodes, resulting from splitup of Limitations of Make.
5425 All cross-references changed. Raise the top node from
5426 a section to a chapter, and all subnodes accordingly.
5427 Redo the introductory wording to match the new organization.
5428 (Installation Directory Variables): Use an example that is
5429 closer to what Autoconf actually does. Mention that VPATH's
5430 value should not contain metacharacters or white space.
5431 (Fortran Compiler): Fix a VPATH bug in an example.
5432 (Leading _ in Macro Names): Mention that this problem is no longer
5433 of practical concern.
5434 (VPATH and Make): Reword the advice to make it clearer
5435 that Autoconf and Automake support VPATH in non-GNU make, but
5436 many packages have bugs in this area.
5437 ($< in Explicit Rules): Refer to Build Directories rather
5438 than using a (non-VPATH-safe) example.
5439 (Automatic Rule Rewriting): Mention the sort of disaster that
5440 can ensue with Solaris-style rule rewriting with VPATH.
5442 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5444 * doc/install.texi (Compilers and Options): Weaken the
5445 suggestion to use GNU make for VPATH builds.
5447 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5448 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5450 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5451 in regular expression.
5453 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5455 * doc/autoconf.texi (Installation Directory Variables):
5456 Drop extra @samp from `@table @samp' item.
5457 (Limitations of Usual Tools): Comment fix.
5458 Do not nest @samp just to point to other table items.
5459 (Writing testsuite.at) <AT_CHECK>: The second argument to
5460 `@dvar' is already @samp'ed.
5461 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5462 do not use @var in the second argument.
5464 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5466 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5467 $as_shell.exe too. Problem reported by Andreas Buening in
5468 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5470 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5472 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5473 `unused variable' compiler warning, for `-Wall -Werror'.
5474 Reported by Jaap Haitsma in
5475 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5477 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5479 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5480 case the compiler dumps core. Problem reported for
5481 OpenServer 5.0.7 by Tim Rice in
5482 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

5486 2006-06-06 Tim Rice <tim@multitalents.net>.
5488 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5489 "ERROR" only shows up in "make check" output if there is an

5513 * config/texinfo.tex: Sync from upstream.
5515 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5516 seen, invoke libtoolize with `--ltdl' argument.
5517 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5519 Suggested by Eric Blake.
5521 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5523 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5524 reported by Ralf Wildenhues.

5531 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5533 * doc/autoconf.texi: Modernize some of the references to Solaris.
5535 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5537 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5538 message issued by AC_REQUIRE.
5539 * tests/m4sugar.at: Check m4_require's error message.
5540 * tests/base.at: Check AC_REQUIRE's error message.
5541 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5543 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5545 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5546 `expout' as the last parameter.
5547 * tests/tools.at: Adapt to the above change.
5549 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5551 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5552 information about race-free implementations of mkdir.
5554 2006-06-04 Eric Blake <ebb9@byu.net>
5556 * bin/autoreconf.in (help): Document M4 environment variable.

5559 * doc/autoconf.texi (autom4te Invocation): Likewise.
5561 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5563 * NEWS: GNU make now recommended for VPATH builds.
5564 Mention that some macros are now documented to be obsolescent.
5565 * doc/autoconf.texi:
5566 Prefer "current" to "modern" to describe
5567 currently-used (albeit perhaps old-fashioned) hosts.
5568 Mention which ancient features no longer need to be worried about.
5569 setgid -> set-group-ID
5570 setuid -> set-user-ID (these are the Posix terms)
5571 Fix some misuses of "only".
5572 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5573 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5574 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

5581 Mention that these macros are obsolescent.
5582 (Installation Directory Variables): shall -> should
5583 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5584 Mention that it's now safe to use 3 and 4.
5585 (Limitations of Usual Tools): cp -r is now specified by Posix.
5586 Omit longwinded and obsolescent discussion of cp -f.
5587 Modernize discussion of expr, ls.
5588 (Limitations of Make): Modernize discussion of VPATH builds.
5589 Mention $? as a workaround in some cases.
5590 * doc/install.texi (Basic Installation):
5591 Mention "./configure; make; make install" first. Be more
5592 specific about why this file is generic. Remove unnecessary
5593 parens. Remove misleading "only". Remove obsolete advice
5594 about csh. Don't say "configure" takes awhile; say it
5595 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5596 and CC=c99 rather than CC=c89, as these are blessed by current
5597 Posix. Recommend GNU make if doing a VPATH build.
5599 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5601 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5602 examples involving shell prompts.
5604 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5605 and Paul Eggert <eggert@cs.ucla.edu>
5607 * doc/autoconf.texi (Here-Documents): Add details about the
5608 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5609 use "here-documents" instead of "here documents".
5611 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5613 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

5617 * doc/autoconf.texi (File System Conventions): Warn about ":"
5618 anywhere in directory names.
5620 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5622 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5623 about quoting the case statement, just in case.
5624 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5625 was fixed in ksh93g; reported by Ralf Wildenhues.
5627 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5629 * doc/autoconf.texi (System Services): Do not document
5630 overriding EXEEXT via ac_cv_exeext=ext.
5631 (Particular Programs) <AC_PROG_MKDIR_P>:

5639 argument with leading hyphen. Problem reported by Paul Eggert.
5641 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5643 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5644 about quoting ac_try: quote all of it, if any of it seems suspicious.
5645 This means we don't have to worry about ${ or sed any more.
5646 Also, double-quote the case statement, to work around misuses via
5647 underquoting as reported by Ralf Wildenhues in
5648 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5649 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5650 undocumented and dangerous macro.

5662 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5663 since evidently some packages rely on the old, broken behavior.
5664 Problem reported by Ralf Wildenhues in
5665 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5666 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5667 pre-2006-05-26 definitions, but leave in the comments that
5668 these macros are dangerous and should not be used.
5669 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5670 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5671 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5672 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5673 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5675 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5677 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5678 the use of 'tr', since this is our only use of 'tr'.
5680 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5681 and Paul Eggert <eggert@cs.ucla.edu>
5683 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5684 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5686 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5688 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5689 the output file in the `${datarootdir}' test.
5691 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5692 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5694 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5695 mention of `datarootdir' in the input file(s), but literal
5696 `${datarootdir}' in the output file, and we haven't warned yet,
5697 then warn as well: the user may have (erroneously) used
5698 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5699 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5700 * tests/torture.at (datarootdir workaround): Extend this test.
5703 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5704 and Paul Eggert <eggert@cs.ucla.edu>
5706 * doc/autoconf.texi (autoheader Invocation): The first argument to
5707 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5708 alternatives and clear up the language a bit.
5710 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5712 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5713 ac_config_guess, ac_config_sub, ac_configure.
5714 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5715 Fix typo that prevented an unnecessary space from being removed.
5716 Problems reported by Ralf Wildenhues in:
5717 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5719 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5721 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5722 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5723 Don't use the term "thread-safe" to talk about mkdir race
5724 conditions, since the problem is more a process than a thread
5725 issue. Problem reported by Stepan Kasal in:
5726 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5727 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5728 the test for 'install' more closely. Look at MKDIR_P first.
5729 Look in the PATH, and at /opt/sfw/bin.
5730 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5731 Don't bother to try mkdir -p, since we already check mkdir --version;
5732 just look at the version number. (There's no easy way to check
5733 for race-free implementations.)
5734 * tests/tools.at (autoconf: subdirectories): Adjust to above
5735 changes, since MKDIR_P now might end in "/mkdir -p".
5737 * doc/autoconf.texi (autoheader Invocation): Mention that the
5738 first arg of AC_DEFINE_UNQUOTED must be a literal.
5739 Problem reported by Ben Pfaff in
5740 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5742 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5743 * doc/autoconf.texi (Special Chars in Variables): New section.
5744 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5745 (Installation Directory Variables): Quote $(datadir) better.
5746 (Limitations of Builtins): Describe some of eval's trickiness.
5748 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5749 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5750 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5751 in front of every arg, not just trailing args. Quote apostrophes.
5752 (_AC_EVAL_ECHO): New macro.
5753 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5754 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5756 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5757 exposed by quoting of eval argument. Put the command on line line
5759 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5760 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5761 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5762 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5763 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5764 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5765 Use eval more safely.
5766 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5767 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5769 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5770 lines, exposed by quoting of eval argument.
5772 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5773 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5775 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5776 initialization of `ac_cv_exeext', do not override it if it was
5777 already set, unless it was set to `no', for compatibility with
5778 Autoconf-2.13, and comment this.
5779 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5780 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5781 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5782 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5783 Document that this test may be overridden by setting
5786 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5788 Revert these two patches:
5790 2006-04-06 Eric Blake <ebb9@byu.net>
5791 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5792 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5795 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5796 Clean up _AC_COMPILER_EXEEXT* macros.
5797 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5798 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5799 ac_file to the name of the default output file and call
5800 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5801 initial `rm' of the candidate files...
5802 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5803 the same list in subsequent `rm' calls, and for the temporary
5804 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5805 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5806 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5807 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5808 no longer needed) by libtool. Make it a cache check.
5809 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5810 copied here by mistake.
5811 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5812 _AC_COMPILER_EXEEXT.
5813 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5814 _AC_COMPILER_OBJEXT directly.
5815 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5817 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5819 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5820 Fix description of how the buggy `sed' works.
5822 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5826 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5827 ENOLCK. Only mention `make -j' when applicable. Only raise
5828 fatal errors when `make -j' is involved. Improve error message.
5830 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5832 * doc/autoconf.texi (Here-Documents): We now know more about
5833 the variable expansion in here documents bug.
5834 Thanks to Tim Rice and Stepan Kasal.
5836 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5837 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5839 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5841 * tests/autotest.at (Multiline command from M4 expansion):
5842 No failure to be expected if the shell quotes newlines in
5843 commands in the `set -x' output. Report by Tim Rice.
5846 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5848 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5849 expansion in the here-documents used by config.status, as that
5850 runs afoul of the Korn shell version M-12/28/93d bug described in
5851 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5852 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5853 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5855 2006-05-23 Jim Meyering <jim@meyering.net>
5857 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5858 Fix typo introduced with 2006-04-02 change. It reversed the sense
5861 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5863 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5864 ac_dB slightly, to save bytes in the script.
5865 Max out at 50 lines, rather than 96; this is more likely
5866 (though not guaranteed) to avoid obscure 'sed' failures.
5868 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5870 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5871 `tr -d -' as bad option argument. Work around this by deleting
5872 an unrelated character.
5873 Report by Tim Rice <tim@multitalents.net>.
5875 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5876 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5877 Stepan Kasal <kasal@ucw.cz>
5879 * doc/autoconf.texi (Particular Programs): Do not promise that
5880 we always prefer the GNU version of the program, and that we
5881 search according to PATH; both rules can have exceptions.
5882 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5883 AC_PROG_SED. Move descriptions of limitations
5884 to the Limitations of Usual Tools section.
5885 (Limitations of Usual Tools) <sed>: Mention script length
5886 limitations with Solaris /usr/ucb/sed.
5887 <grep>: Fix wording for empty alternative. Mention that -c and
5888 -l should not be combined, and that -E and -F should not be
5891 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5892 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5894 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5895 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5897 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5899 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5900 AC_DEFINE is now passed to m4_pattern_allow.
5901 * NEWS: Mention that; likewise for AC_SUBST.
5902 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5903 the parameter to m4_pattern_allow.
5904 * tests/tools.at: Add a check for that.
5906 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5908 * lib/autoconf/status.m4: Fix typos.
5910 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5912 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5913 only the files that this macro generates.
5915 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5917 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5918 the HP-UX sed limitation of 99 commands, labels do not count.
5919 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5921 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5923 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5925 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5926 Import the following fix from coreutils:
5928 2006-01-13 Jim Meyering <jim@meyering.net>
5930 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5931 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5932 not double-quote uses of that variable, to accommodate the rare
5933 case in which getmntent is available in none of the libraries
5934 checked. This happens at least on FreeBSD 5.0.
5936 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5938 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5939 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5940 some other programs unwisely rely on these undocumented vars.
5941 But put in warning comments about them.
5942 Problem reported by Ralf Wildenhues in
5943 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5944 * NEWS: Document that these variables are intended to go away.
5946 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5948 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5949 and set the language to C++ (analogous to the equivalent Fortran
5952 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5953 * doc/autoconf.texi (C++ Compiler): Document it.
5954 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5957 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5959 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5960 that caused config.status to generate 100-command sed scripts; the
5961 portable limit is 99.
5963 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5965 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5966 variable `ac_d' instead of `d' to avoid infringing namespace.
5967 Report by Ralf Menzel.
5969 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5971 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5972 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5973 * tests/tools.at (autoconf: subdirectories): New test, taken from
5974 the corresponding problem report by Ralf Wildenhues in:
5975 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5977 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5978 Quote some uses of shell variables if they might suffer unexpected
5979 globbing. This doesn't fix all instances of quoting problems that
5980 I found, just the easy ones that look safe.
5981 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5982 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5983 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5984 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5985 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5986 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5987 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5989 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5990 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5992 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5994 * bin/autoreconf.in ($help): Reword according to the manual.
5995 Suggested by Olly Betts.
5997 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5998 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6000 * bin/autoreconf.in: Pass the directory argument to
6001 `require_configure_ac'. Fix comment.
6002 * tests/torture.at (Configuring subdirectories): Expose this.
6003 Reported by Olly Betts.
6005 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6007 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6008 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6009 Automake as follows:
6011 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6012 `$configure_in' instead of `configure.in', to preserve
6013 directory component.
6015 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6017 * config/config.guess, config/config.sub, config/texinfo.tex,
6018 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6020 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6022 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6023 test for C99 conformance; (bool) 0.5 is an integer constant
6024 expression, but (bool) -0.5 is not. Problem reported by Fedor
6025 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6027 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6029 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6030 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6031 Warn about obsolete install-sh files. Remove stray sentence
6032 fragment and fix cross reference.
6033 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6034 install -d; this undoes the 2006-05-10 change.
6035 (MKDIR_P): Mark with AN_MAKEVAR.
6036 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6037 that we don't require $INSTALL to be thread-safe. Move comments
6038 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6039 of AC_PROG_INSTALL. Output a message saying that we're checking
6040 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6041 MKDIR_P instead of AC_SUBST.
6042 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6043 Special magic for MKDIR_P, too.
6044 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6046 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6048 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6050 Sync from Automake, as follows:
6052 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6053 * config/install-sh: Initialize IFS, so field splitting isn't
6055 * config/mkinstalldirs: Likewise.
6056 * config/missing: Remove superfluous quotes. Replace all uses of
6057 `[' by `test', for consistency, and for..
6058 * config/missing (sed_minuso, sed_output): New variables.
6059 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6060 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6061 Fixes `missing' to detect `--output' for help2man. Fixes
6062 PR automake/483. Report by Dennis J. Linse.
6063 (autom4te): Document in `missing --help'.
6065 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6067 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6068 * config/install-sh: Don't use 'path' to talk about file names,
6069 as per GNU coding standards. Close a race condition reported by Ralf
6070 Wildenhues and Stepan Kasal. There is still a race condition
6071 on hosts that predate Posix 1003.1-1992, but we can't help this.
6072 Don't mishandle weird characters like space on pre-Posix hosts.
6073 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6074 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6075 AC_PROG_MKDIR_P from AS_MKDIR_P.
6076 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6077 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6078 earlier editions are not (including Automake 1.8.3).
6079 Do not suggest mkinstalldirs for thread-safety.
6080 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6081 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6082 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6083 presence of special characters and race conditions.
6084 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6085 in Autoconf's name space.
6087 2006-05-10 Bruno Haible <bruno@clisp.org>
6088 and Paul Eggert <eggert@cs.ucla.edu>
6090 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6091 from Automake with minor changes.
6092 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6094 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6096 * config/install-sh: Update to Automake CVS version, as follows:
6097 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6098 * lib/install-sh: Simplify the expr implementation of dirname.
6099 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6100 * lib/install-sh: Handle --, and diagnose unknown options.
6102 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6104 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6105 `./autom4te' to create `./testsuite', since the `all' target
6106 will ensure its presence, but `installcheck' should not create
6107 the uninstalled wrappers.
6109 * tests/torture.at (Unusual Automake input files): Skip if we
6110 detect automake < 1.8.
6112 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6114 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6115 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6116 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6119 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6121 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6122 munge (multiple) white space and other oddities.
6123 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6124 single quotes in variable assignment.
6125 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6126 and similar failures by adding multiple spaces, tabs, and other
6128 Report and different test suggested by Francesco Romani
6129 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6131 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6132 single quotes, we only need to search for single quotes; this
6133 both simplifies the search pattern, and makes us less
6134 susceptible to `echo' variations for arguments not containing
6136 (_AC_ARG_VAR_VALIDATE): Likewise.
6138 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6140 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6141 `$*' and IFS concatenation issue with traditional shells and
6142 bash-2.04. Report by Seanster@Seanster.com.
6144 2006-05-03 Bruno Haible <bruno@clisp.org>
6146 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6147 precisely which Mac OS X versions have the od problem.
6149 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6151 * doc/autoconf.texi: Use @option systematically.
6153 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6154 and Bruno Haible <bruno@clisp.org>
6156 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6158 (Integer Overflow): Mention the special case of integer division
6161 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6163 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6164 traditional shells like the Solaris one that do not use the
6165 first IFS character for assembling `$*'.
6166 Prompted by a related report from autoconf_bug@nro.ca.
6168 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6169 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6171 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6172 Mention more problems with the -e option.
6174 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6177 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6179 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6180 in URLs to improve DVI formatted output (requires texinfo 4.6).
6181 (System Services, Systemology, Shellology): Likewise.
6182 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6185 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6187 (Runtime): Fix macro argument names to match description:
6188 `action-if-found' -> `action-if-true' and similarly.
6189 (Obsolete Macros): Likewise.
6190 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6191 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6192 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6194 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6196 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6199 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

6226 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6227 since as_me isn't set yet.
6229 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6231 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6232 a few minor bugs in this area.
6234 * doc/autoconf.texi (Programming in M4sh): Comment out the
6235 documentation of AS_BASENAME, for now.

6271 (Defining Directories): Likewise
6272 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6274 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6276 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6277 newline from the `trap' code to finish `config.log'; the NetBSD
6278 /bin/sh resets the exit status after an empty command, as
6279 documented in doc/autoconf.texi.
6280 Reported by Dalibor Topic <robilad@kaffe.org>.
6282 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6284 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6285 Suggested by Bruno Haible.
6287 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6289 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6290 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6291 Instead, just list the shells that we know work.
6292 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6293 changed. Be more cautious about the _cv_ variable.
6294 * tests/tools.at (Syntax of the shell scripts): Check the
6295 _cv_ variable once, at first, to avoid an internal autoconf error
6296 when sh -n does not work.
6298 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6300 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6302 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6304 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6305 use ">&-" since we're only 99.999% sure that this is portable,
6306 and since the MinGW bug is fixed in a different way.
6307 * lib/autotest/general.m4 (AT_INIT): Likewise.
6309 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6311 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6312 before opening config.log, to avoid hitting a bug on MinGW.
6314 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6316 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6317 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6318 This works around a MinGW bug reported by Eric Paire.
6319 Make sure that all writes to the log file append to it,
6320 rather than possibly losing data.
6321 * lib/autotest/general.m4 (AT_INIT): Likewise.
6323 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6325 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6328 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6332 * configure.ac (AC_INIT): Bump to 2.59d.
6334 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6338 * Makefile.maint (news-date-check): Do not require a leading `*'
6339 before the release date in NEWS.
6341 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6342 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6345 the instantiated file do not contain the string 'datarootdir'
6346 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6347 @mandir@, replace the reference '${datarootdir}' by the value.
6348 * tests/torture.at (datarootdir workaround): New test.
6349 * NEWS: Advertise this temporary fixup.
6350 Based on a patch by Bruno Haible, reported and analyzed by
6351 Paul Eggert and Noah Misch.
6353 2006-04-12 Eric Blake <ebb9@byu.net>
6355 * tests/autotest.at (Debugging a failed test): Fix comment.
6357 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6359 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6360 all the changes since 2006-04-07.
6362 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6364 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6365 succeeded, but `ln -s file dir' failed, take care to remove the
6366 leftover target before the next test, to prevent its spurious
6367 failure; also make sure `ln file dir' works before selecting it.
6368 Thanks to Keith Marshall for pointing this out.
6371 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6372 assignments in `at_debug_args', so that we put them correctly
6373 in the `run' script.
6374 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6375 Reported by Eric Blake.
6377 2006-04-11 Eric Blake <ebb9@byu.net>
6379 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6380 top-level tests after micro-suite has been run. Used in...
6381 (Debugging a successful test, Debugging script and environment),
6382 (Debugging a failed test): ...these new tests. The first of these
6384 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6385 macro, split out from...
6386 (AT_INIT): ...here, so that using -d also generates a run script.
6387 Document that -d inhibits top-level logging.
6388 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6389 inhibits top-level logging; debug scripts are created.
6391 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6393 * tests/autotest.at (Empty test, Empty check): New test to check it.
6395 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6398 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6400 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6401 the files if a problem appears. Make the empty *.at files
6402 read-only, too. Proposed by Ralf Wildenhues.
6404 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6406 * config/Makefile.am: Add comment to force updated Makefile.in.
6408 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6409 space only patch to this file, this patch causes the Makefile.in
6410 files that include freeze.mk to be updated, and thus have a
6411 newer time stamp again, which in turn makes a pristine CVS
6412 checkout have correct time stamps.
6414 * Makefile.maint (cvs-sv): New macro, to be used..
6415 (config.guess-url_prefix, config.sub-url_prefix)
6416 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6417 point to CVS text checkout of Gnulib files.
6418 (copyright-check): Bump current year.
6419 (announcement): Do not hard-wire `./announce-gen'.
6420 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6422 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6424 (wget_files): Update config.guess, config.sub, texinfo.tex by
6425 `wget-update', now that their URLs work again.
6427 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6429 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6430 Problem noted by Paul D. Smith.
6432 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6434 * doc/autoconf.texi: Remove unused words from word list.
6435 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6436 .x-sc_trailing_space: New files.
6438 * doc/standards.texi: Sync from gnulib.
6440 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6441 `LIBOBJDIR' as experimental.
6443 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6444 with a target directory; it's internally implemented as `cp'
6445 anyway, but since Autoconf advertises the possibility to use
6446 a target directory when LN_S is `ln -s', we need to find out.
6447 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6448 analyzed by Keith Marshall <keith.marshall@total.com>.
6452 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6454 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6455 confdefs.h as-is. In general, if it has backslash-newline or the
6456 like, then it doesn't work either to sort or to remove empty
6459 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6461 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6463 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6465 * lib/autom4te.in (Automake-preselections): Preselect
6468 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6470 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6471 apostrophe within a single-quoted string, as this is the usual
6472 tradition and is easier to read than '"'"'. Don't rely on the
6473 shell treating "$/" like '$/'. Use a more-consistent indenting
6476 2006-04-09 Eric Blake <ebb9@byu.net>
6478 * tests/autotest.at (Backquote command substitution),
6479 (Multiline backquote command substitution): Remove mistaken
6480 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6482 (Parenthetical command substitution, Multiline parenthetical
6483 command substitution): here.
6485 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6487 Import macros from gnulib (often changing their name).

6518 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6519 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6520 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6521 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6522 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6523 (Coding Style). Don't mention m4_expand_once.

6545 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6547 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6549 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6550 of the warning introduced by the 2001-08-28 change.

6560 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6562 Revert the patch from 2006-04-01 and only improve
6563 _AS_DETECT_BETTER_SHELL:
6565 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6566 skip nonexistent directories.
6567 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6568 only shell candidates which exist.
6569 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6570 * lib/autotest/general.m4 (AT_INIT): No need to give three
6571 parameters to _AS_PATH_WALK.
6573 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6574 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6576 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6577 distinguish m4sugar macros.
6578 * tests/tools.at (autoupdating with aclocal and m4_include):
6579 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6580 test case by Noah Misch <noah@cs.caltech.edu>.
6582 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6584 Revert my change from 2006-03-17, in other words:
6585 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6587 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

6593 * doc/autoconf.texi (Programming in M4sh): Document that
6594 AS_MKDIR_P exits the script on failure.
6595 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6597 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6599 * config/elisp-comp, config/install-sh, config/mdate-sh,
6600 config/missing, config/mkinstalldirs: Sync from Automake.

6616 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6618 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6619 whether `set' quotes correctly: redirect stderr of the tested
6620 `set', and use a subshell, for Ultrix; use `sed' instead of
6621 `grep' for zsh `set' which may write binary output; match only
6622 at the beginning of a line, to avoid false positives.
6623 In order to avoid false positives by unrelated variables with
6624 multiline content, put the dump algorithm in a subshell and
6625 unset all variables containing newlines (except some which are
6626 special to the shell). Warn about cache variables that are
6629 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6631 * config/config.guess, config/config.sub, config/texinfo.tex:
6634 * tests/mktests.sh: Reword comments.

6640 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6641 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6642 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6643 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6645 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6646 shell issue with double-quoted command substitutions of native
6648 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith

6666 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6668 * tests/Makefile.am (maintainer-check-posix):
6669 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6671 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6672 ac_config_<foo>s again, sometimes normalized, sometimes not.
6673 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6674 (AC_CONFIG_COMMANDS): Do not do so here.
6675 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6676 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6677 2005-07-25 rewrite. Noticed by Noah Misch.
6679 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6680 _AC_PRESERVE_HELP_ORDER, ...
6681 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6683 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6684 inside m4_expand_once; it is redundant.

6687 for --help from Cygnus `configure.'
6689 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6700 Noah Misch <noah@cs.caltech.edu>
6702 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
6703 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
6704 * doc/autoconf.texi (Help Formatting): New node.
6705 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
6707 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6728 TAGS to ac_config_<foo>s.
6729 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.

6742 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6743 Use 'comm' rather than N instances of grep; this also fixes a bug
6744 whereby substrings were incorrectly matched, causing us to not
6745 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6746 (exclude_list): Exclude empty macros.
6747 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

6752 Switch from grep to awk syntax.
6753 (ac_exclude_script): Renamed from ac_exclude_egrep.

6920 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
6921 switch all of them on and of when necessary. Fixes the bug when

7180 newline for portability.
7181 * tests/torture.at (Torturing config.status): Also test 100

7678 calls, so that the final expansion of this macro is shorter.
7679 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7680 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7681 the cleanup there. Use AS_VAR_* macros, to be more general.
7682 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7684 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7686 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7688 2005-09-01 Stepan Kasal <kasal@ucw.cz>

7704 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7706 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7707 in the example. Reported by Bruno Haible.
7708 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7709 "if $undefined_var;" succeeds with my shell.
7711 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7712 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7713 but change the m4_divert_text to m4_divert_once.
7715 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7717 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7718 Work around bug in Solaris /usr/xpg4/bin/awk.
7719 The bug is present in at least Solaris 8 through 10.
7721 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7723 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7724 some evil values and relying on the fact that $* concatenates the
7725 parameters by the first character from IFS.
7727 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7728 Stepan Kasal <kasal@ucw.cz>

7731 first header appears, define AH_HEADER.
7732 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7733 Update limitations about when to call AC_CONFIG_HEADERS.
7734 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7735 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7736 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7737 ``Configuration Actions''; fix their index entries.
7739 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7740 options correctly. Process N-M as M-N if M is smaller than N.
7741 Process ranges correctly so that N-N will run only N.
7742 Sort and uniquify the tests that will be run. If there is more
7743 than one test, reinsert the banners for the tests.
7744 * tests/autotest.at (Keywords): Unmark XFAIL.
7746 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7748 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7749 before passing the macro name to AH_TEMPLATE.
7751 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7752 now opens log after option processing; in particular, --version
7753 and --help do not touch config.log.

7765 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7766 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7769 * doc/autoconf.texi (Defining Symbols, Changed Results):
7770 Prepend to LIBS, not append, in examples.
7772 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7774 When building in place, set srcdir="."; suggested by Tim Van Holder.
7776 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7777 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7778 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7779 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7780 does not mean "no --srcdir option".
7782 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7784 * tests/autoscan.at (autoscan): New file.
7785 * tests/suite.at: Use it.

7793 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7794 add "2>&1"; gzip 1.2.4 prints help on stderr.
7796 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7798 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7799 was pushdef'ed twice while popped only once. Push it only once.
7800 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7802 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7804 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

7809 * Makefile.maint: Update from Bison.
7811 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7812 "<tab>" in comment, so that the point is understandable.
7814 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7816 Rewrite substantial part of lib/autoconf/status.m4.
7817 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7818 and CONFIG_COMMANDS are not processed in four separate loops.
7819 Instead, there is one main loop. This alows that the common code
7820 is expanded only once, thus config.status (and configure) is smaller.
7822 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7823 the AC_LIST_FILES and cousins macros are no longer used.
7825 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7826 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7827 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7828 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7829 contain the initialization, nor the for loop, nor the associated
7830 commands; all these go to ...
7831 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7832 _AC_OUTPUT_CONFIG_STATUS.
7833 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7834 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7835 (_AC_OUTPUT_FILE): The creation of the sed script ...
7836 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7837 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7838 _AC_OUTPUT_MAIN_LOOP.
7839 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7840 _AC_CONFIG_COMMANDS): Use ...
7841 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7842 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7843 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7844 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7845 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7846 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7848 (_AC_CONFIG_UNIQUE): Update.
7849 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7850 Replaced by this ...
7851 (_AC_LIST_TAGS): ... new common macro.
7852 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7853 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7854 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7855 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7856 this didn't belong to the `config commands' section.
7857 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7858 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7859 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7860 to the `config commands' section either.
7861 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7862 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7864 ... and many changes to the comments nearby.
7866 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7867 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7868 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7869 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7870 (#define header templates): The comment at the top of the generated
7871 header now includes the name(s) of the source file(s).
7873 Several unrelated small changes:
7875 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7876 parameter to AC_DIAGNOSE.
7877 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7878 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7879 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7880 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7882 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7883 in AC_OUTPUT doesn't double-quote it either.
7884 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7887 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7889 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7890 versions of Portland Group compiler produce single- and double-quoted
7891 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7892 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7894 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7896 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7897 This is a corrected version of yesterday's patch.
7899 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7901 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

7905 ac_cv_build_alias to ac_build_alias.
7906 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7908 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7909 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7910 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7911 (AC_ARG_VAR): ... here.
7912 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7915 Keep a list of all precious variables and process them with one simple
7916 for loop, instead of expanding all commands, or, OTOH, complicated
7917 processing of output of "set".
7918 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7919 variable names in new macro...
7920 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7921 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7922 a loop to assign all ac_env_* and ac_cv_env_* variables.
7923 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7925 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7926 its value to shell variable ac_precious_vars and call
7927 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7928 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7929 _AC_ARG_VAR_VALIDATE.
7931 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

7959 Fix cases when the varsions of Autoconf and Autotest don't match.
7960 Reported by Noah Misch.
7961 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7962 at_top_builddir, for compatibility with older autotest.
7963 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7964 is not set, use at_top_builddir, for compatibility with older
7965 versions of autoconf.
7967 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7969 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7970 Problem reported by Patrick Welche.
7972 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7974 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7975 sed substitution command, so that we allow | in program prefixes
7976 and program suffixes. (& is a problem anyway; we're not fixing
7978 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7979 configure_input, top_builddir, srcdir, etc.
7980 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7981 PATH_SEPARATOR in AUTOTEST_PATH.
7983 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7985 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7986 for loop over config.site files using `set', to allow
7987 directory names containing IFS characters.
7989 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7991 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7992 directories with weird names. Apparently some people like living
7993 on the edge. However, improve the test that "pwd" actually does
7994 report a name for the working directory.

8014 document to output the default config_* lists to config.status.
8015 Don't recognize option --file, if the functionality is not there.
8016 Likewise for --header; moreover, recognize --he and --h as shortcuts
8017 for --help in that case.
8019 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8020 matches the order of execution. No code changed.

8042 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8043 (AC_SUBST): Call it.
8044 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8045 the directory specific variables; but don't call it for configure_input.
8047 2005-06-28 Derek Price <derek@ximbiot.com>
8049 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8052 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8054 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

8075 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8076 Don't worry about backslashes in srcdir; it can't happen now.

8120 * doc/autoconf.texi:
8121 Don't mention Solaris versions so much, if a
8122 problem is common to all extant versions of Solaris. Say "SunOS
8123 4" instead of "SunOS" for SunOS 4.
8124 (awk): Mention more of the limitations of traditional Awk.
8125 (cat): Don't talk about cat -v.
8127 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
8129 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
8130 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

8137 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
8138 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8139 Use shell builtins rather than 'expr', to work around expr bug.
8141 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8143 * doc/autoconf.texi: "filesystem" -> "file system".
8144 "behaviour" -> "behavior".
8145 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8146 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8148 * lib/m4sugar/m4sh.m4: Likewise.
8149 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8150 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8152 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8153 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8154 to update the man page. That way, we don't have to check in new
8155 man pages every month.
8157 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8158 quotes and backslashes. Patch from Derek Price.
8160 2005-06-10 Derek Price <derek@ximbiot.com>
8162 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
8165 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8167 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8168 -u, since it outputs chatter if the input files are the same.
8169 Problem reported by Ralf Menzel.
8171 2005-06-08 Derek Price <derek@ximbiot.com>
8173 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8174 renaming them since they are about to be redefined anyhow.
8176 2005-06-08 Derek Price <derek@ximbiot.com>
8178 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8179 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8180 Move m4_undefine to alphabetical order.
8182 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8184 * README: Recommend GNU M4 1.4.3 or later.
8185 * doc/autoconf.texi (Introduction): Likewise.
8186 Reword to avoid some formatting glitches.
8187 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8188 Clarify explanation of HP compiler bug.
8189 Redo example output tp match current CVS snapshot.
8190 Use @example.org in email addresses when the examples
8191 might get inadvertently cut-and-pasted into user code.
8192 Remove example of autom4te usage that doesn't seem to work now.
8193 Use modern AC_INIT (except when the example is meant to be
8194 shown with Autoconf 2.13).
8195 Update ksh info for Solaris 9 and later.
8197 Modernize description of Automake versions a bit.
8198 Don't claim a future version of Autoconf is near.
8199 * doc/install.texi: Reword to avoid some formatting glitches.
8201 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8203 * doc/autoconf.texi: Add [] to examples, so that the manual
8204 follows its own advice about quoting better.
8205 Reword to avoid some formatting glitches.
8206 * doc/installt.exi: Reword to avoid some formatting glitches.
8208 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8209 Tru64 ksh pattern matching bug. Reported against Libtool by
8210 Albert Chin <libtool@mlists.thewrittenword.com> and
8211 Nicolas Joly <njoly@pasteur.fr>.
8213 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8215 m4_cdr of one-member list was [[]] (one-member list containing an
8216 empty string) instead of [] (an empty list. Callers were skewed to
8217 match this misbehaviour. As a consequence of this:
8218 - m4_foreach([x], [], [foo]) expanded to `foo', while
8219 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8220 This bug has been fixed:
8222 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8223 expand to an empty string; print error msg if called without
8225 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8226 misbehaviour; handle [] and [[]] correctly.
8228 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8230 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
8231 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
8232 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8234 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8236 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8237 swallow records with more than 99 fields.
8238 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8239 parse the long line.
8241 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8243 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8244 swallow literals longer than 399. Reported by Ralf Wildenhues.
8245 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8246 to workaround this limitation.
8248 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8250 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8251 to gfortran, and make these the first two compiler names
8252 checked (following the general autoconf preference for gcc).
8254 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8256 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8257 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8258 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8260 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8262 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8263 expression of unbounded size when processing the --list
8264 option. This runs afoul of a limit of 399 bytes per regular
8265 expression on AIX. Problem reported by Ralf Wildenhues.
8267 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
8269 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
8270 * doc/autoconf.texi (Particular Headers): Reword example
8271 for multiline stdbool replacement.
8272 (Setting Output Variables): Reword text a bit. Don't
8273 give all the details about |#_!!_#|.
8274 Reword description of line replacement.
8276 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8278 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8279 now contain newlines, and substituted files must be referenced on
8280 a line alone; the sed scripts to substitute them are now very
8282 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8283 commands can be put in a sed script portably.
8284 * doc/autoconf.texi (Setting Output Variables): Document above
8285 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8286 use of multiline substitution.
8287 * tests/torture.at: No longer expect substitution of newline to fail.
8289 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>

8292 From Ralf Menzel (trivial change).
8294 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8296 * tests/local.at: Don't attempt to check for negated character
8297 classes in shell scripts. The test was too brittle.
8299 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8301 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8302 * doc/autoconf.texi (Limitations of Builtins): Document this
8305 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8307 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8308 common code; used in many places in the tree.
8309 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
8310 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8312 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
8314 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
8315 messages when ac_unique_file is not found.
8316 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8317 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8318 commands, for consistency with AC_MSG_ERROR and such.
8320 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8322 * bin/Makefile.am: Merge the two rules for creating scripts.
8324 2005-05-23 Stepan Kasal <kasal@ucw.cz>

8328 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
8330 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8332 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8333 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8334 (ac_top_builddir): ... this ...
8335 (ac_top_build_prefix): ... to this; the old name is also kept, for
8336 backward compatibility.
8337 (ac_top_builddir_sub): New variable, without the trailing slash,
8339 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8340 * doc/autoconf.texi (Configuration Actions): Rename
8341 ac_top_builddir to ac_top_build_prefix.
8342 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8343 at_top_builddir to at_top_build_prefix.

8348 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
8351 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8353 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8354 argument to m4_foreach. I guess it was necessary in the past,
8355 but I think it's a no-op now.
8357 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8359 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8360 ``cat <<_ACEOF'' commands to one.
8361 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8362 * lib/autoconf/status.m4: On various places, use expr instead of
8364 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8365 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8366 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8368 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8369 the wrong patterns between ``case'' and ``esac.'' The previous
8370 code had false positives.

8439 quoting rules. Problems noted by Stepan Kasal.
8440 Also, throughout this document, be more careful about white space.
8441 "blank", "white space", and "space" all have different meanings
8442 and we should be careful to say what we mean.
8444 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

8463 set by latest automake.
8465 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8467 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"

8485 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8487 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8489 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8491 * doc/autoconf.texi (External Software): Quadrigraphs are not
8492 processed correctly in AS_HELP_STRING; avoid this in the examples.
8493 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8494 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8495 comment and reduce m4_default([foo], []) to [foo].
8496 (m4_strip): Update the explanation.
8498 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8500 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8501 Remove core.conftest.* too; it's generated by Tru64 5.1.
8502 Problem reported by Jennis Pruett.
8503 * lib/autoconf/functions.m4
8504 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8505 Don't bother to remove core files; AC_RUN_IFELSE should do that
8508 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8510 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8555 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8556 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8558 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8560 * NEWS: The configure command now warns you if you attempt to use
8561 a directory whose name contains a special character like space,
8563 * doc/autoconf.texi (Installation Directory Variables): Allow
8564 "," in file names. Do not use \@; it's not a portable regexp.

8579 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8581 * doc/autoconf.texi: Fix some systematic formatting problems.
8582 ".)" needs a following @: if not at the end of a sentence, and
8583 similarly for "!)". "etc." should be preceded by a comma.
8584 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8586 2005-03-22 Bruno Haible <bruno@clisp.org>
8588 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8589 argument is often called 'build-aux'.
8591 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8593 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8594 macro AC_TRY_LINK is obsolete.
8595 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8598 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8600 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8601 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8602 from a Common Lisp's `cl'.
8603 (AC_PROG_CXX): Behave according to the documentation: don't
8604 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8605 make the variable CCC precious; use `cl.exe', not `cl'.
8607 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8608 Alexandre Duret-Lutz <adl@gnu.org>
8610 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8611 /dev/null, as "configure" shouldn't read stdin, and this insulates
8612 us from problems (e.g., when testing for "cl"). Also, do this
8613 redirection before invoking "hostname" or "uname", and keep the
8614 original input stream available via...
8615 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8616 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8617 bother with "</dev/null" since it's now done at the top of
8619 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8620 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

8626 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8628 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8629 newline if neither \c nor -n work, as that would output two
8630 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8632 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8634 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8635 This causes that any required macros inside will get before the if.
8636 * doc/autoconf.texi (autom4te.cache): A typo.
8638 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8640 Undo previous change, except keep the change to
8641 lib/autoconf/programs.m4 that replaced grep with shell
8642 pattern-matching. This is because net-snmp configure reads stdin.
8643 Reported by Noah Misch.
8645 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8647 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8648 from /dev/null, as "configure" shouldn't read stdin, and this
8649 insulates us from problems (e.g., when testing for "cl").
8650 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8651 before invoking "hostname" or "uname".
8652 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8653 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8654 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8655 "</dev/null" since it's now done at the top of 'configure'.
8656 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8657 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8658 Also, replace grep with shell pattern-matching, to save a process.
8660 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8662 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8663 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8664 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8667 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8669 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8670 grep -q isn't portable. Improve grep -s explanation.
8671 Problem reported by Dan Manthey.
8673 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8675 * doc/autoconf.texi (Special Shell Variables): Clarify
8676 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8678 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8680 * doc/autoconf.texi: Use @acronym for DJGPP.
8681 Fix some @code's that should have been @env's, and vice versa.
8682 Sort environment variable names.
8683 Mention that shells no longer inherit IFS.
8684 Don't recommend PATH_SEPARATOR=';' so strongly.
8685 Mention that $RANDOM might expand to the empty string.
8686 "symlink" and "soft link" -> "symbolic link".
8687 Improve mktemp description (reported by Bruno Haible).

8763 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8765 Try not to generated lines of unlimited length, as POSIX places a
8766 2047-byte limit on line length of portable text files.
8767 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8768 Use newline as a separator, not space.

8826 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8827 Update the long comment explaining it.
8829 m4_require no longer writes an ``is required by'' line to the
8830 execution stack. It contains only one bit of non-redundant
8831 information: that the macro was required, not called. And even
8832 this bit is useless in most situations: have you ever met a macro
8833 which both calls and requires the same macro?
8835 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8836 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8841 execution stack; slightly improve the out-of-a-defun error message.
8842 (_m4_divert_grow): New macro, counter for the temporary diversions.
8843 (_m4_require_call): Use it.
8844 * tests/m4sugar.at (m4_require): Expect output without the
8845 ``is required by'' messages.
8847 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8849 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8850 rather than x for expr.

8881 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8883 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8884 Warn about newline stripping in `` and $(). Update Solaris
8886 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8887 X insulates us from future changes to Posix.
8888 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8891 2005-01-19 Stepan Kasal <kasal@ucw.cz>
8893 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

8913 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
8915 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

8936 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
8937 (_m4_divert_n_stack): New macro; the expansion is
8938 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8940 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8941 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8942 stored in _m4_divert_diversion or _m4_divert_dump.
8943 (m4_divert_pop): When the parameter is given, compare the symbolic
8944 name with the last diversion pushed on the stack. Previously, the
8945 current diversion was compared with the numeric value of the
8946 diversion given as the parameter.
8947 (m4_require): If the macro hasn't been expanded yet, call ...
8948 (_m4_require_call): this new macro.

8981 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
8982 signals that the package uses Automake; a `Makefile.am' is typical but
8983 not essential. Reported by Magnus Therning.

9034 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
9035 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are
9036 no longer part of the macro, quote the occurrence of ``$tmp''.

9514 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9515 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9518 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9520 * doc/autoconf.texi (File System Conventions): Warn about
9521 names like "aux". Problem reported by Eric Blake.
9523 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9524 by zero instead of array size, so that we can use any arithmetic
9525 constant expression (instead of requiring an integer constant
9526 expression). This allows us to test expressions like DBL_MAX <
9527 LDBL_MAX, which didn't conform to the C standard using the old
9529 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9530 now that we can do floating-point tests at compile time.
9532 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9534 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9535 and LDBL_EPSILON, as the resulting expression isn't an
9536 integer constant expression and violates the C standard.
9537 Problem reported by Nelson H. F. Beebe. Also, check
9538 for "L" suffix, and check that long double doesn't have
9539 worse range or precision than double, that mixed-mode
9540 arithmetic doesn't generate a diagnostic, that double
9541 constants fit in long double.
9543 2004-06-03 Kevin Ryde <user42@zip.com.au>
9545 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9546 malloc(0) and realloc(NULL,size).
9548 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9551 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9553 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9554 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9557 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9559 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9560 can be rewritten using if-then-else. Suggested by Bruno Haible.
9562 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9564 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9565 Problem reported by Stepan Kasal.
9567 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9569 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9570 change). Patch reported by Ralf Wildenhues in
9571 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9573 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9574 function F exists if the compiler and linker let you compile an
9575 expression like (F != 0). Recent versions of GCC optimize away
9576 the reference to F in that case, since every function address must
9577 be nonzero, so the link succeeds even if F does not exist.
9578 Problem reported by Manu in
9579 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9581 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9582 "Unix". Many uses changed.
9583 (Limitations of Builtins): Explain better why the ! command isn't
9586 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9588 * lib/autom4te.in (Automake-preselections): Preselect
9589 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9591 2004-05-19 Kevin Ryde <user42@zip.com.au>
9593 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9594 referencing AC_FUNC_STRERROR_R.
9596 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9597 note pessimistic assumption when cross compiling.
9599 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9601 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9602 (until 2004) invoked subcommands with sh -e, contra POSIX.
9603 Reported by Kevin Ryde.
9605 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9607 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9608 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9609 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9610 `test -f " /usr/bin/grep"', which _always_ failed.
9611 (AC_PROG_SED): Ditto bogus PATH fix.
9612 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9613 requires that grep correctly supports _multiple_ `-e' options, rather
9614 than stating only that grep should accept `-e'.
9616 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9618 Port to C99, which requires that 'exit' be declared.
9620 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9621 to ensure that stdlib.h is included.
9622 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9623 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9624 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9625 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9626 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9627 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9628 when using 'exit' in a test; C99 requires that 'exit' be declared.
9630 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9632 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9633 now prefers 'grep' implementations that accept -e.
9634 (Limitations of Usual Tools): Describe problems of traditional
9635 egrep and fgrep with long input lines, and of traditional grep
9637 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9638 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9639 All callers changed. Append /usr/xpg4/bin to the PATH, for
9641 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9642 the user with complaints about multiple -e options.
9643 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9644 Define it with AC_PROG_GREP.
9645 * configure.ac (AC_PROG_GREP): Add.
9646 * lib/freeze.mk (GREP): New macro.
9648 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9650 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9651 a possible candidate only after all others fail, rather than
9652 consulting it first. This improves backward compatibility by
9653 better reflecting the way shell selection occurred in previous
9654 versions of Autoconf, and should help to avoid triggering latent
9655 problems in other packages, such as the one in Automake where zsh
9656 is not handled robustly:
9657 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9658 Although it is not Autoconf's responsibility to work around
9659 problems in Automake, it nevertheless makes sense to avoid
9660 introducing unnecessary incompatibilites.
9662 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9663 Gary V. Vaughan <gary@gnu.org>
9665 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9666 how deeply nested we are when a suitable tool is found, set the
9667 ac_path_TOOL_found flag.
9668 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9669 nested we are in this macro. Break out of all 3 nested loops if
9670 ac_path_TOOL_found is set.
9672 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9674 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9675 of the _AS_PATH_WALK loop too if GNU flavor is found.
9677 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9679 * doc/autoconf.texi (Limitations of Make): Update documentation
9680 for `$<'. New entry `Long lines', based on a report from Simon
9681 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9682 paragraph about DJGPP, based on a mail from Richard Dawe.
9684 2004-04-20 Paul Eggert <eggert@twinsun.com>
9686 * tests/c.at (C keywords): Don't assume that GCC supports
9687 "restrict" and "inline", as sufficiently-old GCC versions do not
9688 (also, GCC configured to be in pedantic C89 mode does not).
9689 Problem reported by Sumit Pandya in:
9690 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9692 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9693 consider -g to work if it generates warnings when plain compiles
9694 don't. Problem reported by Braden McDaniel in:
9695 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9697 * doc/autoconf.texi (Slashes): New section, to document a problem
9698 reported by Jim Meyering in:
9699 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9701 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9702 linker output files before linking, to work around IRIX 6 linker bug.
9703 Problem reported by Rainer Orth in:
9704 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9706 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9708 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9709 best tool so far counter rely on the tool path variable name to
9710 avoid checks for one tool being affected by the results of running
9711 the length check on a previous tool.
9713 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9714 match expression argument, as different greps have different
9715 regular expression flavours.
9716 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9718 (AC_PROG_EGREP): Pass 'EGREP$'.
9719 (AC_PROG_GREP): Pass 'GREP$'.
9721 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9723 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9724 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9726 2004-03-29 Paul Eggert <eggert@twinsun.com>
9728 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9729 Types, Specific Compiler Characteristics, System Services,
9730 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9731 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9732 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9733 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9735 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

9746 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9747 now defines HAVE_DECL_TZNAME if it is declared, when
9748 HAVE_STRUCT_TM_TM_ZONE is not defined.
9749 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9750 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

9819 * bin/Makefile.am (edit): Don't use $< in a context where
9820 POSIX doesn't require support for it. Use $@.in instead.
9821 Problem reported by Anthony N. Frasso in
9822 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

9855 Darwin uses -lcrt2.o and there's little point to cataloging all
9856 the system variants. Partial fix reported by Andreas Waechter in:

9979 2004-01-26 Paul Eggert <eggert@twinsun.com>
9981 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9982 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9983 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9984 not <inttypes.h>. Problem reported by Tim Mooney in
9985 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9986 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9989 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9990 otherwise "make check" fails because it forbids cmp (I guess
9991 because cmp treats files as binary on DOS-like systems).
9993 * tests/mktests.sh: Update copyright date to 2004, since some tests
9994 have changed in 2004.
9996 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9998 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9999 non-truncating sed or gsed program in PATH.
10000 * tests/acprograms.at: Add it.
10001 * doc/autoconf.texi (Particular Programs): Document it.
10004 2004-01-15 Paul Eggert <eggert@twinsun.com>
10006 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10007 -std1 disables some useful extensions on Tru64. Problem reported
10008 by N. Lichtmaier in
10009 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10011 2004-01-14 Paul Eggert <eggert@twinsun.com>
10013 * doc/autoconf.texi (Programming in M4sh): Document that
10014 AS_MKDIR_P succeeds if the destination is a symbolic link
10015 to an existing directory.
10016 (Limitations of Usual Tools): Note that mkdir -p might not
10017 succeed on symlinks to directories.
10019 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10021 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

10031 2004-01-10 Jim Meyering <jim@meyering.net>
10033 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10035 2004-01-09 Paul Eggert <eggert@twinsun.com>
10037 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10038 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10039 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10040 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10041 AC_COMPILE_IFELSE, since we now assume our caller invokes
10042 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10043 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10044 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10045 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10047 2004-01-07 Paul Eggert <eggert@twinsun.com>
10049 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10050 `"'...'"`, as it's confusing (and I suspect it may not work on
10051 some platforms). The code was incorrect anyway, as it assumed
10052 that \$ evaluated to itself in that context. Reported by
10053 Alexandre Duret-Lutz.
10055 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10057 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10058 and _LT_AC_TAGCONFIG.

10062 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10063 example, and add more examples. Reported by Eric Sunshine.

10081 by doing lineno substitution only on lines containing "$LINENO".
10083 2004-01-04 Paul Eggert <eggert@twinsun.com>
10085 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10086 Use "rm -f" to remove conftest.sed, not plain "rm".
10087 Bug reported by David Relson in
10088 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10090 * Makefile.am (autom4te-update):
10091 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10092 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10093 * doc/autoconf.texi (Guidelines): Likewise.

10103 Warn against "rm -fr".
10105 2004-01-03 Paul Eggert <eggert@twinsun.com>
10107 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10108 -c -o might not work. From a suggestion by Kevin Ryde.
10109 (C Compiler, Generating Sources, Limitations
10110 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10111 Don't put '-o' after non-options, as POSIX doesn't allow this.
10112 Mention that cc's name might be gcc or c89 or whatever.
10114 2004-01-04 Kevin Ryde <user42@zip.com.au>
10116 * doc/autoconf.texi: Add various further index entries.

10120 * bin/autoreconf.in (autoreconf_current_directory):
10121 Fix typo: mkdir without umask arg.
10123 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10125 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10126 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10127 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10128 explanation clearer.
10130 2003-12-24 Andreas Schwab <schwab@suse.de>
10132 * doc/autoconf.texi (Default Includes): Fix misspelling of

10138 * configure: Regenerate.
10139 * tests/atlocal.in: Store the result here.
10140 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

10142 of explicitly testing.
10143 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10144 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10145 * tests/tools.at (Syntax of the shell scripts): Simplify
10146 using AT_CHECK_SHELL_SYNTAX.

10148 AT_CHECK_PERL_SYNTAX.

10230 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10231 than $target since the latter is not usual, add guidelines on when to
10232 use or not use the system type.

10236 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

10439 cache variable instead of $G77 to decide whether to include -O2,
10440 since $G77 is specific to Fortran 77.
10442 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10444 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10445 free" flag. Re-order flags tested into rough order of popularity.
10447 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10449 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10450 arguments so that it can be used with syntax identical to
10451 AC_PROG_F77, and so that we can more easily decide to
10452 remove/deprecate the DIALECT optional argument in the future if it
10453 proves troublesome.
10454 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10455 non-freeform-supporting compilers. Document freeform flags.
10457 2003-10-03 Akim Demaille <akim@epita.fr>
10459 * configure.ac: Look for emacs, not macs.
10460 Reported by Eric Sunshine.
10462 2003-10-03 Akim Demaille <akim@epita.fr>
10464 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10465 * bin/autoreconf.in (autoreconf_current_directory): Create the
10466 AUX_DIR if needed, for sake of automake --add-missing etc.
10467 Suggested by Alexandre Duret-Lutz.
10469 2003-10-03 Akim Demaille <akim@epita.fr>
10471 * configure.ac: Quotation and formatting changes.
10472 (EMACS): Don't set it if it is not recent enough to support

10518 Problem reported by Lars J. Aas in
10519 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10520 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10521 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10522 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10524 2003-09-26 Akim Demaille <akim@epita.fr>
10526 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10527 directory for AC_CONFIG_COMMANDS' first argument exists.
10528 This makes valid the invocation of _AC_SRCPATH that follows.
10529 Reported by Eric Sunshine.
10530 * doc/autoconf.texi (Configuration Commands): Adjust.
10532 2003-09-26 Akim Demaille <akim@epita.fr>

10539 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10541 Actually, use AU_ALIAS.

10553 The test suite are sometimes assigning timings incorrectly.
10554 Reported by Henk Krus.
10555 Diagnosed by Nicolas Joly.
10557 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10559 Instead of making AT_help a sequence of assignments to grow
10560 $at_help_all, just make AT_help_all be the growing contents of
10561 $at_help_all, and make a single assignment in...
10563 (at_times_skip): Flip the meaning and rename as...
10564 (at_times_p): this.
10565 (AT_INIT): When summarizing the test that ran, remove
10566 $at_times_file after use, and check it is present before trying to
10569 2003-09-25 Akim Demaille <akim@epita.fr>
10573 * bin/Makefile.am (edit): Handle '@configure_input@'.
10574 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10575 (ifnames): chmod -w.
10576 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10577 executables, not bin/ executables! Otherwise all the magic needed
10578 to find non installed files is turned off. This caused a failure
10579 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10580 as found in its environment (sent by tests/autoreconf): pointing
10581 to bin/autom4te that could not find its files.
10582 * tests/mktests.sh: Force the replacement of generated files, for
10583 the sake of "mv" program that are interactive when overwriting a
10585 * config/install-sh: Upgrade from CVS Automake.
10587 2003-09-23 Paul Eggert <eggert@twinsun.com>

10592 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10593 Paul Eggert <eggert@twinsun.com>
10595 Trivial change to support GCC's configuration procedure.
10596 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

10598 about inconsistency if the preprocessor is set to give errors for

10631 willing to edit the output files.
10633 2003-09-10 Akim Demaille <akim@epita.fr>
10635 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10636 and AC_FC_FREEFORM.

10674 2003-09-04 Akim Demaille <akim@epita.fr>
10676 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10678 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10680 Add support for newer Fortran dialects. The F77 interface is
10681 unchanged, and continues to support Fortran 77. New FC macros
10682 correspond to all the old F77 macros, with output variables FC,
10683 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10684 available dialect, but older dialects can be specified. There are
10685 new macros AC_FC_SRCEXT to set the source extension, and
10686 AC_FC_FREEFORM to accept free-form source files.
10688 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

10724 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10725 are defaulted by AT_CHECK anyway.
10726 Use AT_CHECK_AUTOM4TE.

10804 2003-08-21 Akim Demaille <akim@epita.fr>
10806 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10808 ($help): Use Autom4te::ChannelDefs::usage.
10809 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10810 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10812 2003-08-21 Akim Demaille <akim@epita.fr>
10814 First stab at preserving warnings between calls to autom4te,
10815 including when the cache is used.
10817 There are still several issues: (i) there are too many runs of m4
10818 (one for include, one for warnings, and some more), (ii) warnings
10819 spreading on several lines are not handled gracefully, (iii) the
10820 code meant to have the call stack display for errors does not work
10821 (its handling should move from m4 to autom4te).
10823 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10825 (@preselect): Add m4_warn.
10826 ($exit_status): Remove, use $exit_code.
10827 ($help): Use Autom4te::ChannelDefs::usage.
10828 (&handle_m4): No longer define the m4_warnings.
10829 At each run, extract and report the warnings.
10830 Always cache the result, including if the exit status is on
10831 failure, since if nothing changes, we should result in the same
10832 failure, hence we can use the cache.
10833 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10834 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10836 (m4_warn): Redefine as a do-nothing: it is its invocation that
10837 matters, as warnings are now reported via traces.
10838 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10839 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10840 the latter reveals calls to the former.
10844 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

10873 Reported by Alexandre Duret-Lutz.

10877 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10878 * bin/autom4te: Adjust.
10879 In particular, be Autoconf tools are really silent when properly
10880 working, bind the verbosity of the 'note' channel to $verbose.
10881 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10882 (&xsystem, &contents): Remove, since they are exported by...

10954 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10955 (AT_CHECK_NOESCAPE): Move core functionality to...
10956 (_AT_CHECK): ...this new macro.
10958 2003-08-07 Derek Price <derek@ximbiot.com>
10960 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10961 (AT_CHECK_NOESCAPE): ...to this new macro.
10963 2003-07-31 Paul Eggert <eggert@twinsun.com>
10965 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10966 in Bash 2.01. Problem reported by Brian Gough in
10967 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10969 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10971 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10972 -lcrt1.o, for OS X. (trivial change)
10974 2003-07-07 Paul Eggert <eggert@twinsun.com>
10976 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10977 inside '#ifndef __cplusplus'. Problem reported by
10980 2003-07-06 Bill Clarke <llib@computer.org>
10982 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10983 'long', not 'int', for benefit of Sun's recent C++ compilers
10984 (trivial change). See:
10985 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

10991 * lib/Makefile.am (autom4te.cfg): Make it read only.
10992 Depend on Makefile since it contains substitutions.
10993 From Paolo Bonzini.
10994 * lib/autom4te.in (args): Add local.at? for Autotest args.
10995 This change was made on autom4te.cfg which is generated.

11000 * doc/autoconf.texi (Header Portability): sys/mount.h.
11001 From Gareth McCaughan.
11003 2003-06-23 Akim Demaille <akim@epita.fr>
11005 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11006 not all of them. This fixes 1. the fact that when testing
11007 Autoconf there are many many config.log, 2. the incorrect use of
11008 top_srcdir to find config.log.
11009 Don't mix the detailed output of failed test with the summary of
11010 failures. Rather, append detailed log afterwards.
11012 2003-06-23 Akim Demaille <akim@epita.fr>
11014 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11015 always run: output config.log on $at_group_log.
11017 2003-06-23 Akim Demaille <akim@epita.fr>
11019 * tests/torture.at (#define header templates): Don't use quotes in
11020 C++ comments as it puzzles Emacs' sh font-lock-mode.
11022 2003-06-23 Akim Demaille <akim@epita.fr>
11024 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
11025 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
11026 * tests/atspecific.m4: Rename as...

11035 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
11036 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
11037 ensuring we add -std1 for full-ANSI.
11039 * doc/autoconf.texi (hdrindex): New macro.
11040 Add index entries for portability of various standard header files.
11042 2003-06-20 Akim Demaille <akim@epita.fr>

11050 2003-06-20 Akim Demaille <akim@epita.fr>

11068 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
11069 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.

11072 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11073 (AT_INIT): Support for expected failures.
11075 2003-06-02 Akim Demaille <akim@epita.fr>
11077 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

11080 Autoconf nor Automake.
11081 (&contents): New, from Automake.
11084 2003-05-28 Paul Eggert <eggert@twinsun.com>
11086 * NEWS, doc/autoconf.texi (Particular Functions),

11088 is the inverse of localtime.

11092 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11093 (handle_exec_errors): New function. Work around $! being
11094 altered by WEXITSTATUS.
11095 (xqx, xsystem): Use handle_exec_errors.
11097 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11099 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11100 Do not call `_exit()', simply modify `$?'.
11101 (xsystem): Reset $! before running system, and check it afterward.
11102 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11103 63 for version mismatches.
11105 2003-05-23 Akim Demaille <akim@epita.fr>
11107 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11108 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11109 the middle of a line).
11110 * lib/m4sugar/m4sugar.m4: Likewise.
11111 Remove useless spaces in comments.
11113 2003-05-23 Akim Demaille <akim@epita.fr>
11115 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11116 exit 63, so that we (or Automake's "missing") can tell the
11117 difference with a plain failure.
11118 * doc/autoconf.texi (Notices): Adjust.
11120 2003-05-23 Akim Demaille <akim@epita.fr>
11122 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11123 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
11124 White spaces cleanup.
11126 2003-05-22 Jim Meyering <jim@meyering.net>
11127 Paul Eggert <eggert@twinsun.com>
11129 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11130 Remove `#include <stdlib.h>' from the list; we should never
11131 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11132 resulting namespace pollution would cause other tests to fail.
11133 Configure scripts run with some older versions of g++ and HP's
11134 aCC would fail due to such an #include. Problems reported by
11135 Matthew Mueller in <http://bugs.debian.org/120704> and by
11137 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11138 In the test, use the test declaration before including <stdlib.h>,
11139 as that's closer to how it'll be used.
11141 2003-05-23 Akim Demaille <akim@epita.fr>
11143 * doc/autoconf.texi (Header Portability): ucred.h.
11146 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11148 Overhaul Autotest's logging: generate separate log files
11149 in testsuite.dir/NNN/testsuite.log, and append them to
11150 testsuite.log instead of re-running the test verbosely.
11152 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11153 file descriptor, write 0 to at_status_file instead of setting
11154 at_status=0, initialize some new variables (at_status_file,
11155 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11156 to rerun the tests, instead append the at_group_log to the
11157 at_suite_log when a test fails.
11158 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11159 with the AS_MESSAGE_LOG_FD redirected to stdout.
11160 (AT_CLEANUP): save the output status in $at_status_file
11161 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11162 its original place.
11163 (AT_CHECK): since tests are run with a redirected stdout,
11164 and used to be re-run in verbose mode, turn some $at_verbose
11165 into echo, and don't redirect the output of testing stdout
11168 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11169 the name of the debugging directory and information about

11286 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
11289 2003-05-06 Akim Demaille <akim@epita.fr>
11291 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11292 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11293 by aclocal.m4 is changed it might require the importing of another
11294 m4 extension file, i.e., aclocal must be run.
11296 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11297 (&parse_args): Use --force with aclocal if required and supported.
11298 (&autoreconf_current_directory): Use &run_aclocal.

11311 2003-04-29 Derek Price <derek@ximbiot.com>
11313 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11314 seperator with m4_append_uniq(). It doesn't work.
11315 (AT_CLEANUP): Add `;' to end of at_help_all.
11316 (AT_INIT): Allow --keywords to be specified more than once. When
11317 grepping $at_help_all for keywords, use the field and keyword
11318 seperators to ensure a complete keyword match. Alter at_prev handling
11319 to support the new --keywords behavior.
11321 2003-04-27 Karl Berry <karl@freefriends.org>
11323 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11324 align better with others. I also made some of the individual
11325 entries on one line, for brevity and to make it easier for me to
11326 sort my dir-example file in the Texinfo distribution :).

11393 header causes problems.
11395 2003-03-28 Akim Demaille <akim@epita.fr>
11397 * tests/torture.at (Configuring subdirectories): Require aclocal
11398 1.4, otherwise the test fails, as it does support configure.ac.

11489 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
11490 to cope with DOS-style absolute paths, when constructing
11493 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11494 When constructing paths with IFS=:, quote the path. If we're
11495 constructing a DOS-style absolute path, we don't want to split it
11498 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo

11518 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11519 format starting with "-".
11521 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11523 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11524 is not portable inside Makefile.
11526 2003-02-20 Akim Demaille <akim@epita.fr>
11528 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

11546 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11547 innocuous variant befor including <limits.h> or <assert.h>. This
11548 works around a bug reported by Albert Chin: HP-UX 11i
11549 (and earlier versions) have a <limits.h> that declares
11550 gettimeofday and many other functions.
11552 2002-12-03 Paul Eggert <eggert@twinsun.com>
11556 * NEWS, configure.ac: Update version.
11558 * doc/fdl.texi: Upgrade to FDL version 1.2.
11560 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11561 nontrivially in main's body, so that f's external declaration is
11562 not optimized away in AIX. This should fix the bug reported by
11564 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11566 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11567 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11568 defined, to support freestanding compilers. This should fix the
11569 bug reported by Momchil Velkov in
11570 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11572 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11573 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11604 Update from masters.
11606 2002-11-14 Akim Demaille <akim@epita.fr>
11608 * Makefile.maint: Sync with Bison, i.e.:
11609 (po-check): Scan .l and .y files instead of the
11610 .c and the .h files that they generate. This fixes the bug
11611 reported by Tim Van Holder in:
11612 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11613 Look for N_ as well as for _. Try to avoid matching #define for
11617 2002-11-14 Akim Demaille <akim@epita.fr>
11619 * doc/autoconf.texi (C Compiler): Compiling several files at once.

11629 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11630 than assigning in main, to avoid HP cc +O3 optimizing it away.

11634 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11635 option. Process --recheck after parsing all options. Pass -q
11636 option to configure on --recheck.
11637 (AC_OUTPUT): Pass -q from configure to config.status.
11638 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11639 arguments to record.
11640 * doc/autoconf.texi (config.status Invocation): Document
11641 config.status -q option.
11643 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11645 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11646 Makefile.in if Makefile.am exists.
11647 (output): Strip `.am' from Makefiles. Don't
11648 output AC_CONFIG_FILES if no Makefiles were found.

11668 Reported by Ezra Peisach.
11670 2002-11-05 Akim Demaille <akim@epita.fr>
11672 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11674 We _have_ to stop using the old compatibility scheme that tried to
11675 avoid useless backslashes because Libtool 1.4.3 contains a
11676 AC_DEFINE([error_t], [int],
11677 [Define to a type to use for \`error_t' if it is not
11678 otherwise available.])
11679 We _have_ to quote the single quote and backslashes with \. The
11680 old compatibility scheme saw that ` was backslashed, and therefore
11681 did not quote the single quote. Hence before this patch, Autoconf
11682 was not compatible with Libtool.
11684 2002-11-04 Paul Eggert <eggert@twinsun.com>
11686 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11706 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11708 2002-10-31 Bruno Haible <bruno@clisp.org>

11726 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11727 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11728 Make variable, not a shell variable.
11729 Suggested by Bruno Haible.
11731 2002-10-31 Akim Demaille <akim@epita.fr>
11733 * bin/autom4te.in (load_configuration): Reject #args out of any
11736 2002-10-31 Akim Demaille <akim@epita.fr>
11738 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

11752 2002-10-29 Paul Eggert <eggert@twinsun.com>

11755 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11756 Problem reported by Bruno Haible.
11758 2002-10-29 Akim Demaille <akim@epita.fr>
11760 * doc/autoconf.texi (Header Templates): Put also in words what the
11761 pictures says to assist free style readers.
11762 (Customizing autom4te): s/--cache=/--cache /.
11764 2002-10-29 Akim Demaille <akim@epita.fr>
11766 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
11768 sparc_address_test returns void.
11769 Use it with an argument, as prototyped.
11772 2002-10-29 Akim Demaille <akim@epita.fr>

12073 Reported by Alexandre Duret-Lutz.
12075 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12132 From Sam Varshavchik.
12134 2002-10-08 Akim Demaille <akim@epita.fr>
12136 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12137 aclocal invocation, as Gettext macros might not be visible to
12139 Instead of blindly running autopoint, scan configure.ac (not the
12140 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12141 Reported by Paul D. Smith.
12143 2002-10-08 Paul Eggert <eggert@twinsun.com>

12173 * tests/torture.at (Configuring subdirectories): Be robust to

12399 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12400 looking for a replacement file.
12401 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12402 directory is relative.
12403 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12404 directory definition.
12405 Reported by Andreas Schwab and Jim Meyering.

12409 * doc/autoconf.texi (Setting Output Variables): Clarify what
12410 precious variables are.
12411 Suggested by Pontus Skoeld.
12413 2002-09-05 Akim Demaille <akim@epita.fr>
12415 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12416 (ifnames, autoscan, autom4te): Since we don't only depend on
12417 configure.ac variables (such as VERSION etc.), but also on prefix
12418 and so forth, depend on Makefile, not configure.ac.
12419 Reported by Alexandre Duret-Lutz.
12420 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12422 2002-09-05 Kevin Ryde <user42@zip.com.au>
12424 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12425 doesn't seem to be confined to ia64, just say "some versions".
12427 2002-09-04 Akim Demaille <akim@epita.fr>
12429 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12431 * Makefile.am (maintainer-clean-local): Remove.
12432 (MAINTAINERCLEANFILES): Remove COPYING.
12434 2002-09-03 Paul Eggert <eggert@twinsun.com>
12436 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12437 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12440 2002-09-03 Akim Demaille <akim@epita.fr>
12442 * configure.ac: Bump to 2.53d.
12443 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12444 as of today, on Automake's team suggestion.
12446 2002-09-03 Akim Demaille <akim@epita.fr>
12450 2002-09-02 Akim Demaille <akim@epita.fr>
12452 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12454 * configure.ac: Disable SITE_MACRO_DIR.
12456 2002-09-02 Jim Meyering <meyering@lucent.com>
12458 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12459 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12460 Also, tweak grammar: s/make sure to/be sure to/.
12462 2002-09-02 Paul Eggert <eggert@twinsun.com>
12464 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12465 directory names are generally preferable to physical names.
12467 2002-09-02 Akim Demaille <akim@epita.fr>
12469 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12470 Reported by Raja R. Harinath.
12471 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12472 * bin/autoupdate.in: Use error instead of die.
12474 2002-09-01 Paul Eggert <eggert@twinsun.com>
12476 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12477 ordinary shell concatenation rather than echo+tr+sed command that
12478 runs afoul of a long-line-related sed bug in Solaris 8.
12480 * bin/autoheader.in (parse_args): --warning -> --warnings.
12482 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12483 stdout, as traditional "ls" does.
12484 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12485 _AC_COMPILER_EXEEXT_O): Likewise.
12486 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12488 * bin/autoconf.as: Add --prepend-include option. This patch was
12489 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12490 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12492 * bin/autoconf.in, configure: Regenerate.
12494 * doc/autoconf.texi (Special Shell Variables): Mention
12495 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12497 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12498 MAILPATH and set PS1, PS2, PS4 to default values, to work
12499 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12500 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12501 the Autoconf documentation specifies; fall back to "unset" only if
12502 this fails. Use a shell for-loop for this rather than an m4 loop,
12503 to shorten the output script.
12505 2002-08-30 Paul Eggert <eggert@twinsun.com>
12507 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12508 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12509 for the CDPATH problem. Document PWD.
12510 (Limitations of Builtins): Document the problem that "cd $foo" and
12511 "ls $foo" may refer to different directories in shells conforming
12512 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12513 example, since the old example is now out of date.
12515 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12516 FOO" and "ls FOO" talk about different directories; this catches
12517 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12520 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12521 of rolling our own unset.
12522 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12523 in practice we needn't worry about CDPATH if unset doesn't work.
12525 * Makefile.in, aclocal.m4, bin/Makefile.in,
12526 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12527 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12528 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12529 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12530 tests/Makefile.in: Regenerate with Automake 1.6.3.
12532 * config/config.guess, config/config.sub, config/mkinstalldirs:
12535 * configure: Regenerate with self.
12537 2002-08-30 Kevin Ryde <user42@zip.com.au>

12547 2002-08-29 Akim Demaille <akim@epita.fr>
12549 * lib/Autom4te/General.pm (&xqx): New.
12550 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12551 hand, which is not portable.
12553 * bin/autom4te.in: Use them.
12554 Use &error instead of die.
12555 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12558 2002-08-17 Paul Eggert <eggert@twinsun.com>
12560 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12561 default list of compilers to try, since it was long ago superseded
12562 by the ksh fc builtin. Suggested by Steven G. Johnson.
12564 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12566 * doc/autoconf.texi (Invoking autom4te): End the option table,
12567 fixing a bug introduced by the previous patch.
12568 (Limitations of Make): Add a 'target lookup' subentry in the
12569 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12571 2002-07-29 Mark D. Roth <roth@feep.net>
12573 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12574 options and use $AUTOM4TE_PATH.
12575 * doc/autoconf.texi: Remove documentation of autom4te
12576 --include-envvar and --site-macro-subdir options and document
12577 use of $AUTOM4TE_PATH.
12578 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12579 arguments from each language section.
12581 2002-07-29 Paul Eggert <eggert@twinsun.com>
12583 * doc/install.texi: Include copyright symbol in copyright notice.
12585 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12587 (AM_MAKEINFOFLAGS): New macro.
12588 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12589 * Makefile.am (INSTALL): Use the new macros.
12590 Use -o rather than --output, since "missing" does not grok --output.
12592 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12594 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12595 comments do not always work. Never trust the exit status of
12598 2002-07-24 Kevin Ryde <user42@zip.com.au>
12600 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12601 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12603 2002-07-23 Paul Eggert <eggert@twinsun.com>
12605 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12606 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12607 apparently treats PATH="nonexistent" as if it contained ".".
12608 Bug reported by Stefan `Sec' Zehl.
12610 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12612 * doc/autoconf.texi (Limitations of Make): Mention the special

12872 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12874 2002-05-17 Paul Eggert <eggert@twinsun.com>
12876 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12877 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12878 This improves on an earlier suggestion by H. Peter Anvin.
12880 2002-05-16 Paul Eggert <eggert@twinsun.com>
12882 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12883 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12884 Both macros now accept an optional source-dir arg.
12885 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12887 * NEWS: Document this.
12888 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12890 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12891 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12892 not for GNU extensions; this undoes part of the 2000-11-03 change,
12893 reverting to 2.13-compatible behavior.
12894 Add new optional argument DIR.
12895 (AC_FUNC_FNMATCH_GNU): New macro.
12897 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12899 2002-05-08 Paul Eggert <eggert@twinsun.com>
12901 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12902 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12903 and it causes a 'test' syntax error if it fails.
12904 Bug reported by Stephen Gildea.
12906 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12907 If prototypes are supported, use them to check this at compile-time,
12908 instead of trying to check it at run-time. If we must do a run-time
12909 check, assume that setvbuf is standard when cross-compiling, as
12910 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12911 Bug reported by Paul D. Smith.
12913 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12914 argument specifying location of getloadavg.c. This removes a
12915 FIXME. This idea was taken from Jim Meyering's implementation in
12917 * doc/autoconf.texi (Particular Functions): Document this.
12918 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12919 that's what the code does; this fixes a bug reported by
12922 2002-05-03 Akim Demaille <akim@epita.fr>
12924 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12925 autopoint instead of gettextize.
12926 ($uses_alocal): Rename as...
12927 ($uses_aclocal): this.
12928 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12929 Suggested by Bruno Haible.
12931 2002-05-03 Akim Demaille <akim@epita.fr>
12933 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12935 2002-04-29 Paul Eggert <eggert@twinsun.com>
12937 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12938 files to be 1 second older; just set them to be the same time.
12939 Also, sleep 1 second after the first aclocal, to work around
12940 problems with sub-second time stamps on the input files.
12942 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12944 * doc/autoconf.texi: Mention "set -e -x" lossage
12945 under node "Limitations of Builtins".
12947 2002-04-29 Akim Demaille <akim@epita.fr>
12949 * doc/install.texi: Better wording for setting variables when
12951 From Christian Cornelssen.
12953 2002-04-29 Akim Demaille <akim@epita.fr>
12955 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12956 of lack of $LINENO support, then the test will compare the $LINENO
12957 in testsuite vs. the lineno in the test file. This is wrong, of
12959 Be sure to protect it.
12960 Reported by Patrick Welche.
12962 2002-04-25 Akim Demaille <akim@epita.fr>
12964 * doc/autoconf.texi (Obsolete Macros): Typo.
12965 Reported by Vladimir Volovich.
12967 2002-04-25 Akim Demaille <akim@epita.fr>
12969 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12970 than some of the input files, hence, on the second run of aclocal,
12971 if some of its input are younger, make them older.
12972 Suggested by Paul Eggert.
12974 2002-04-25 Akim Demaille <akim@epita.fr>
12976 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12977 Thanks to Paul Eggert.
12979 2002-04-25 Akim Demaille <akim@epita.fr>
12981 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12982 and ac_subst_vars be sh variables containing the list of
12983 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12985 (_AC_INIT_PREPARE): Use them to log them.
12986 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12987 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12988 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12989 _AC_SUBST_FILES and _AC_SUBST_VARS.
12990 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12992 2002-04-24 Akim Demaille <akim@epita.fr>
12994 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12995 autoheader, so that automake does not complain about a missing
12996 config.h.in that was to be created.
12998 2002-04-23 Akim Demaille <akim@epita.fr>
13000 * bin/autoheader.in (parse_args): --warning takes an argument.
13003 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
13005 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

13050 Minor spelling and grammar fixes.
13052 * doc/autoconf.texi: Follow the outline suggested in the GNU
13053 Sample Texts sections of the Texinfo 4.2 manual. Most
13054 importantly, this makes sure that the copyright notices appear in
13055 all output formats. You probably need Texinfo 4.2 to generate

13095 * doc/autoconf.texi (Shell Substitutions): Explain it.
13096 From Oliver Kiddle and Peter Stephenson.
13098 Have M4sh perform minimal shell sanitizing.
13100 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13102 (_AS_PREPARE): this new macro.
13104 (AS_INIT): Invoke AS_SHELL_SANITIZE.
13105 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
13107 Adjust Autoconf and Autotest.
13109 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
13110 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.

13118 * tests/wrapsh.as: New, precursor of wrapsh.in.
13119 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13120 on Autotest and M4sh.
13121 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13122 (wrapsh.in): New target.

13141 2002-04-05 Akim Demaille <akim@epita.fr>
13143 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
13144 directories when descending in a SUBDIRS.

13147 2002-04-04 Andreas Schwab <schwab@suse.de>

13156 Use dnl, not the KILL diversion.
13158 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13159 (AC_CONFIG_LINKS): here.
13161 Don't use the KILL diversion, as it kills spurious output, which
13162 results in failures being hidden.
13163 Use m4_defn where appropriate.
13164 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13165 after the second argument.
13167 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13168 syntax, as it is provided by M4sugar.

13210 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13211 to avoid versions of HP C which don't allow that.
13213 2002-03-27 Paul Eggert <eggert@twinsun.com>
13215 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

13229 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13230 as POSIX requires, as it doesn't work with Zsh.
13231 * doc/autoconf.texi (Assignments): Document the problem.
13233 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13235 * doc/autoconf.texi (Limitations of Make): Mention more issue
13236 about VPATH, overriding of macros in sub-makes, and handling of
13239 2002-03-21 Paul Eggert <eggert@twinsun.com>
13241 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13242 problem with here-document buffer boundaries.
13244 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13245 when reinvoking the shell, to work around problems with installers
13246 who put strange things like "cd" commands in their environments.

13270 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13271 (Limitations of Usual Tools): Add mkdir section.
13273 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13274 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13275 back on AS_DIRNAME to compute prefixes otherwise; this is
13276 roughly what mkinstalldirs does. That way, we need not have
13277 our own filename disassembler. The old disassembler did not
13278 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13280 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13281 Create at_test_all by a series of assignments,
13282 not by a single assignment of a long string. The latter causes ksh
13283 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13284 presumably because of a buffer overrun.
13286 2002-03-14 Paul Eggert <eggert@twinsun.com>
13288 * lib/autotest/general.m4 (at_times_skip):
13289 Renamed from at_times. Now a boolean.
13290 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13291 says 'times: not found'.

13336 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13338 2002-03-08 Akim Demaille <akim@epita.fr>
13340 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13341 aliases the actual variables, and modifications of the former
13344 2002-03-08 Akim Demaille <akim@epita.fr>
13346 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

13374 2002-03-04 Akim Demaille <akim@epita.fr>
13376 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13379 2002-03-04 Akim Demaille <akim@epita.fr>
13381 * doc/autoconf.texi (Transforming Names): Equality between target
13382 and host is irrelevant.
13383 (Specifying Names, Canonicalizing): Remove all references to the
13384 backward compatibility hooks. Rather, collect them all into...
13385 (Hosts and Cross-Compilation): this new section.
13386 * doc/install.texi (System Type): Ditto.
13387 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13388 that `--host' implies cross-compilation.
13390 2002-03-04 Akim Demaille <akim@epita.fr>
13392 * doc/autoconf.texi (Evaluation Macros): New.
13393 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13395 (_m4_foreach): Define the variant with immediate evaluation so
13396 that it contains exactly the items, not an expression which
13397 evaluation is the current item.
13398 (m4_re_string, m4_re_word): Don't over quote them.
13400 2002-03-04 Akim Demaille <akim@epita.fr>
13402 Instead of having stacking `shift's evaluated at the end, let
13403 `foreach' loops immediately evaluate them.
13405 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13406 $*. This is the n-th time I change my mind, but hopefully this is
13409 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13411 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13412 it was only a hack for m4_text_wrap.
13413 (m4_car2): Remove, replaced by...
13415 (_m4_foreach): Adjust.
13416 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13417 m4_bpatsubst for clarification.

13469 AC_PREFIX_PROGRAM fails with dashed program names
13471 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13472 variable when looking for the prefix program.
13473 Now it also works for shell variables.

13490 sure not to introduce newlines in at_groups.

13501 Describe HP-UX cc bug workaround more accurately.

13504 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13505 cross-compilers, too. This undoes some of the most recent change
13508 2002-02-05 Akim Demaille <akim@epita.fr>
13510 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13511 to make sure they are up to date when `check' is run.
13513 2002-02-05 Akim Demaille <akim@epita.fr>
13515 * doc/autoconf.texi (Making testsuite Scripts): Document
13518 2002-02-05 Akim Demaille <akim@epita.fr>

13527 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13528 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13530 2002-02-05 Akim Demaille <akim@epita.fr>
13532 * bin/autom4te.in (&parse_args): Implement `frozen files are
13533 optional are the sum of the previous files on the command line'.
13534 Also, pass `--reload-state=' on them, so...
13535 (handle_m4): don't.
13536 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13537 (M4sh): Rely on M4sugar.
13538 (Autotest, M4sh, M4sugar): Use frozen files.

13550 2002-01-30 Akim Demaille <akim@epita.fr>

13572 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13575 2002-01-28 Akim Demaille <akim@epita.fr>
13577 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13578 AUTOTEST_PATH *after* it was set.
13579 Don't put `.' in the PATH: the user should be precise and `./' if
13580 needed. In addition, given that the test suite does some `cd', if
13581 `.' is in the path, the `tested programs' sections will report
13582 programs found in the test suite's directory, while during the
13583 tests (performed in their own directory), these programs are no
13584 longer visible. In other words, the results is confusing and
13586 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

13597 2002-01-24 Akim Demaille <akim@epita.fr>
13599 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13600 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13601 Bourne. Use /bin/sh.
13602 From Andreas Buening.

13630 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13631 message on invalid options.
13632 * bin/autom4te.in (parse_args): Don't use
13633 Autoconf::General::getopt with non valid options.
13635 2002-01-17 Jim Meyering <meyering@lucent.com>
13637 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13638 $ac_cv_exeext so we don't use an old, invalid, cached value.
13640 2002-01-11 Akim Demaille <akim@epita.fr>

13652 package.m4, since is really depends upon configure.ac, not
13654 * doc/autoconf.texi (testsuite Scripts): Adjust.
13655 * tests/Makefile.am (package.m4): New.
13656 EXTRA_DIST it since its a source.
13658 2002-01-06 Akim Demaille <akim@epita.fr>
13660 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13661 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13662 and PACKAGE_BUGREPORT from here...
13663 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13665 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13666 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13667 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13668 * tests/tools.at (autoheader): Adjust.
13669 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

13688 * doc/autoconf.texi (New Macros): Tweak wording.
13690 2001-12-14 Akim Demaille <akim@epita.fr>
13692 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13693 trailing files, don't apply `-rf' to files which might not be
13694 created by configure (core, core.*, and *.core), but just `rm -f'.
13695 Suggested by Jonathan Kamens.
13697 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13699 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

13721 2001-12-12 Kevin Ryde <user42@zip.com.au>

13724 forbidden file descriptors table.
13726 2001-11-26 Akim Demaille <akim@epita.fr>
13728 * bin/autoscan.in (%c_keywords): Build it at top level.
13729 Map to 1 in order to simplify its uses.
13731 2001-11-26 Akim Demaille <akim@epita.fr>
13733 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13734 Remove $filepath, useless.
13735 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13736 variables, they are really part of the tokens.
13737 Split the input line on spaces and then look for tokens.
13738 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13739 because of `lex$U.$(OBJEXT)'.
13740 (&scan_files): Use "@list" instead of join.
13741 * doc/Makefile.am (CLEANFILES): Add *.fns.

13746 Remove, replaced by...
13747 * tests/wrappl.in: Be common for all the Perl executables.
13748 In particular autoscan and autoheader want -I.
13749 * configure.ac: Adjust.
13750 * lib/autoscan/headers: errno.h is portable.
13752 2001-11-26 Akim Demaille <akim@epita.fr>
13754 * bin/autoscan.in (used): New.
13757 2001-11-26 Akim Demaille <akim@epita.fr>

13779 Test groups are now run two directories deeper.
13781 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13782 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13784 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13785 top_srcdir, builddir and top_builddir.
13786 Use `at_*dir' relatively to the directory containing the
13787 suite, use `*dir' when relatively to the current group dir.

13796 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13798 * doc/autoconf.texi (Using System Type): Add an example of `case
13799 $host' usage so people quit using `case $target' everywhere.
13801 2001-11-22 Akim Demaille <akim@epita.fr>
13803 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13804 spotted by Jim Meyering.
13806 2001-11-16 Paul Eggert <eggert@twinsun.com>
13808 This patch implements a `long double' suggestion by Oliver Kiddle.
13810 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13811 static, to catch errors if the value isn't known at compile-time
13812 and the compiler supports dynamic arrays. Change its name from
13813 `_array_' to `test_array' to avoid potential name clashes.
13814 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13815 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13816 better than double. Catch a bug in GCC 2.95.2 x86.
13817 * doc/autoconf.texi (C Compiler): Document the above.
13820 2001-11-13 Akim Demaille <akim@epita.fr>
13822 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by

13826 2001-11-13 Akim Demaille <akim@epita.fr>
13828 * lib/autotest/general.m4 (AT_INIT): After having run the test
13829 group, go back to the initial directory, not to at_suite_dir.
13831 2001-11-13 Akim Demaille <akim@epita.fr>
13833 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13834 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13835 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13837 (AT_CHECK_CONFIGURE): Use absolute paths.
13838 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13839 The problem is still the old one: there is no means in M4 (that I
13840 know about) to create a defining macro, because there is no means
13841 to create `$1' etc., therefore, the defining macro ``swallows''
13842 all the arguments meant to the defined macro.
13844 2001-11-13 Akim Demaille <akim@epita.fr>
13846 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.

13853 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13854 variable names when referring to a single test group, or to
13855 `suite' when referring to the whole test suite.
13856 `at_last_test' is removed: m4 compute at_format itself.
13857 (at_stdout, at_stder1, at_stderr): New variables.
13858 (AT_CHECK): Use them.
13860 2001-11-13 Akim Demaille <akim@epita.fr>
13862 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13864 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13865 Do it as soon as a test fails, don't wait till the end of the test
13867 Don't remove $as_me.[0-9]*, since these files no longer exist.
13869 2001-11-13 Akim Demaille <akim@epita.fr>
13871 * tests/tools.at: Use absolute paths, since we are no longer run
13874 2001-11-13 Akim Demaille <akim@epita.fr>
13876 Now that tests are running in their own private dir, there is no
13877 need to list the files to remove at the end of tests groups.
13879 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13880 (AT_data_files, at_data_files): Remove.
13881 (AT_CLEANUP, AT_DATA): Simplify.
13883 Remove the group dir if !debug && !failed.
13884 * tests/atspecific.m4: Adjust.
13886 2001-11-13 Akim Demaille <akim@epita.fr>
13888 Start a new layout for Autotest: `testsuite' creates
13889 `testsuite.dir' in which the at-check-line etc. files are to be
13890 found, and `testsuite.dir/003' where the test group 3 is run.
13892 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13893 at_check_line_file, at_format, at_test_normalized, at_group_dir
13895 Create the directories.
13896 Use absolute paths for at- files.
13897 (AT_CHECK): Adjust.
13899 2001-11-11 Michael Matz <matz@kde.org>
13901 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13903 (m4_car): Properly quote arguments.
13905 2001-11-13 Akim Demaille <akim@epita.fr>
13907 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13908 with stricter rules on LIBOBJS.
13910 2001-11-12 Paul Eggert <eggert@twinsun.com>
13912 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13913 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13916 2001-11-12 Akim Demaille <akim@epita.fr>
13918 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13920 2001-11-12 Akim Demaille <akim@epita.fr>

13925 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13926 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13927 specify to what the macro should be defined (typically to 1).
13929 2001-11-12 Akim Demaille <akim@epita.fr>
13931 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13934 2001-11-12 Akim Demaille <akim@epita.fr>
13936 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13937 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13938 definition used by Automake where LEX is +/- "${missing} lex" and
13939 `missing' itself contains variables.
13941 2001-11-12 Akim Demaille <akim@epita.fr>
13943 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13944 Now that M4sh pushes BODY, the comments were output at the end of
13947 2001-11-08 Akim Demaille <akim@epita.fr>
13949 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13950 that we can trace macros from aclocal.m4.
13951 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13952 obsoleted, and redirect to the former anyway.
13953 Reported by Ralf Corsepius.
13955 2001-11-08 Akim Demaille <akim@epita.fr>
13957 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13958 processed only if present.
13959 * tests/torture.at (Configuring subdirectories): Use autoreconf
13960 instead of successive calls to autoconf.
13961 Add a nonexistent subdirectory to exercise the patch above.
13962 Reported by Ralf Corsepius.
13964 2001-11-08 Kevin Ryde <user42@zip.com.au>
13966 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13967 doesn't accept .S files.

13973 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13974 * bin/autom4te.in (warn_forbidden): New.
13975 (handle_output): Use it.
13976 Read m4_pattern_forbid with messages.
13978 2001-11-05 Akim Demaille <akim@epita.fr>
13980 * bin/autom4te.in (--normalize): Remove.
13981 * lib/autom4te.in: Adjust.
13983 2001-11-05 Akim Demaille <akim@epita.fr>
13985 * tests/Makefile.am (testsuite): Rename this target as...
13986 ($(TESTSUITE)): this.
13989 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13991 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13992 the --prefix option, also remove it's argument.
13994 2001-11-05 Akim Demaille <akim@epita.fr>
13996 * doc/autoconf.texi (testsuite Invocation): Update.
13997 (Writing testsuite.at): Update.
13999 2001-11-03 Akim Demaille <akim@epita.fr>
14001 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14003 2001-11-03 Akim Demaille <akim@epita.fr>
14005 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14006 (&file_name_is_absolute): New, wrappers around routines from
14008 Use and export them.
14009 (&find_configure_ac): Optionally take a directory where to look at.
14010 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14012 Default @ARGV to `.', not find_configure_ac.
14013 (&autoreconf): Argument is a directory.
14014 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14015 * doc/autoconf.texi (autoreconf Invocation): Update.
14017 2001-11-03 Akim Demaille <akim@epita.fr>
14019 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14020 (@export_forward_subs): New.
14021 Add basename, dirname, and fileparse.
14023 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14024 Don't look for aclocal flags if we already know aclocal is not
14026 Move aclocal.m4t only if it exists.
14027 Reported by Ezra Peisach.
14029 2001-11-03 Akim Demaille <akim@epita.fr>
14031 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14032 passed on command line, defaulting to ./configure.ac if present.
14033 (&maybe_autoreconf, File::Find): Remove, unused.
14034 (&autoreconf): If autoconf is not used, don't try to trace.
14036 2001-11-02 Akim Demaille <akim@epita.fr>
14038 * configure.ac: Bump to 2.52g.
14040 2001-11-02 Akim Demaille <akim@epita.fr>
14044 2001-11-02 Akim Demaille <akim@epita.fr>
14046 * config/config.guess, config/config.sub, doc/standards.texi:
14047 * config/lispdir.m4: Update from masters.
14048 * configure.ac: Bump to 2.52f.
14050 2001-11-02 Akim Demaille <akim@epita.fr>
14052 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14053 Don't run aclocal when aclocal.m4 is not from aclocal.
14055 Don't run libtoolize and gettextize if --install is not given.
14057 2001-11-01 Paul Eggert <eggert@twinsun.com>
14059 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14060 be invoked before _AS_LINENO_PREPARE.
14061 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14062 than character ranges.
14064 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14065 invoking AS_BASENAME. Set the locale variables to 'C' if
14066 possible, as POSIX requires this to get the traditional
14068 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14070 2001-10-31 Paul Eggert <eggert@twinsun.com>
14072 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14073 with {}, as that triggers a bug in Bash 2.05.
14075 (_AS_LINENO_PREPARE): Use Sed rather than
14076 Awk. Fix the sed prepass to work even if there are multiple
14077 instances of $LINENO on the same line. Do not substitute for
14078 other variables like $LINENOT. Do not check file dates; such a
14079 check is unreliable on sufficiently fast machines, and removing
14080 the check makes the code simpler and more reliable. Check for
14081 output and chmod failures.
14083 * doc/autoconf.texi (Special Shell Variables): Document
14086 2001-10-31 Akim Demaille <akim@epita.fr>
14088 * tests/Makefile.am (atconfig): Remove this target, Automake
14091 2001-10-31 Akim Demaille <akim@epita.fr>
14093 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14094 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14095 provided, while it is optional.
14096 * configure.ac: Adjust.
14098 2001-10-26 Paul Eggert <eggert@twinsun.com>
14100 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14101 lib/Autom4te/Struct.pm:
14102 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14105 * doc/autoconf.texi (Special Shell Variables): Document some
14106 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14108 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14109 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14110 eval $LINENO is not portable in practice.
14112 2001-10-24 Akim Demaille <akim@epita.fr>
14114 * lib/Autom4te/General.pm (backname): New.
14116 2001-10-24 Akim Demaille <akim@epita.fr>
14118 * m4/: Remove, merged into...
14121 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14123 * doc/autoconf.texi (Shellology): Mention the problems with bash
14124 2.05's use of ANSI quoting in its `set' builtin.
14126 2001-10-22 Paul Eggert <eggert@twinsun.com>
14128 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14129 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14130 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14131 POSIX decided to standardize on the int flavor of strerror_r.
14132 Always do char* test, as there's no reason not to.
14133 Assign to a char* var, to catch strerror_r that returns int*.
14135 * doc/autoconf.texi (Particular Functions):
14136 Document the above changes. Also, document the fact that
14137 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14139 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14141 2001-10-20 Akim Demaille <akim@epita.fr>
14143 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

14146 2001-10-20 Akim Demaille <akim@epita.fr>
14148 * lib/Autom4te/General.pm (&update_file): If destination is
14149 unchanged, remove the source.
14150 (&up_to_date_p): Don't be verbose, be debug.
14151 * bin/autoreconf.in: No longer support --m4dir.
14152 (&autoreconf): Display the full path of the configure.ac we are
14154 Trace it only once.
14155 Be sure to honor --force with gettextize.
14156 Always run aclocal.
14157 * doc/autoconf.texi: Adjust.
14159 2001-10-20 Akim Demaille <akim@epita.fr>
14161 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14163 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14164 `intl' is already present, as it refuses unless --force.
14165 (&parse_args): Use -I, --include instead of the old Autoconf
14167 ($localdir, $autoconf_dir): Remove.
14169 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14171 2001-10-19 Jens Petersen <petersen@redhat.com>
14173 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

14183 2001-10-19 Akim Demaille <akim@epita.fr>

14189 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14191 * bin/autoreconf.in (autoreconf): Display the path to the
14192 configure.ac being studied.
14194 2001-10-18 Paul Eggert <eggert@twinsun.com>
14196 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14197 long, to work around a bug in the HP C compiler version HP92453-01
14200 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14201 (AS_BASENAME_EXPR): New macro.
14202 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14203 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14204 and fall back on 'sed' only if the other two fail. This makes
14205 AS_BASENAME act more like AS_DIRNAME.
14206 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14207 contains white space.
14208 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14209 Use AS_DIRNAME, since I think it's now DOS-friendly.
14210 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14211 Allow "dirname //FOO" to return either / or //, as POSIX allows
14214 2001-10-10 Akim Demaille <akim@epita.fr>
14216 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

14222 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14223 m4_define, since...

14260 (Syntax of the shell scripts): Don't.

14351 shell does not support LINENO, and if CONFIG_SHELL is unset or
14352 empty, and if we can find a shell that does support LINENO,
14353 then set CONFIG_SHELL to that shell and then re-execute
14354 ourselves with CONFIG_SHELL.

14358 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

14401 compatibility with POSIX shells.

14440 Check for `expr' arithmetic overflow, and for compilation failure,
14441 and invoke a new argument $4 if either is discovered.
14442 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14443 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

14477 * tests/fortran.at (GNU Fortran 77): there.
14478 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14479 AC_TRY_RUN is about compilation, not shell commands.

14522 Don't compute at_srcdir nor at_top_srcdir.
14524 * tests/tools.at: Hence use top_srcdir.
14526 * tests/Makefile.am, tests/autoconf, tests/autoheader,

14584 * tests/Makefile.am (package.m4): Remove.
14586 2001-09-22 Akim Demaille <akim@epita.fr>
14588 Rely on `$LINENO' when possible instead of `__oline__'.

14607 2001-09-21 Akim Demaille <akim@epita.fr>
14609 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14610 Suggested by Jim Meyering.
14612 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14614 * lib/autoconf/programs.m4: Use extensions listed in

14644 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14646 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14653 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14655 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14656 already have $file). Set output files to binary mode (helps avoid
14657 CR issues on DOSish systems).
14659 2001-09-19 Akim Demaille <akim@epita.fr>
14661 * lib/autotest/general.m4: Englishoes.
14662 From Tim Van Holder and Alexey Mahotkin.
14664 2001-09-18 Paul Eggert <eggert@twinsun.com>
14666 * doc/autoconf.texi (Common Shell Constructs): New node,
14667 documenting AS_DIRNAME.
14668 (Limitations of Usual Tools): Refer to it when discussing dirname.
14669 Also, update discussion of POSIX standard to reflect latest draft.
14671 * lib/autoconf/c.m4:
14672 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14674 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14675 Do not pass a first argument with leading '-'
14676 to expr, by parenthesizing initial integers that might be negative.
14678 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14679 now merely checks whether it is an error to pass an argument
14682 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14683 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14684 whether it is a (compile-time) error to pass an argument to
14685 getpgrp. This simpler test supports the revised documentation,
14686 and is all that AC_FUNC_GETPGRP's users really need.
14688 2001-09-18 Akim Demaille <akim@epita.fr>
14690 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14700 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14702 Add test for AS_BASENAME.
14703 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14704 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14705 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14706 * tests/base.at: Fixed the expected responses. The old ones were
14708 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14709 the documentation claims it should (and how it behaved in 2.13).
14711 2001-09-18 Akim Demaille <akim@epita.fr>
14713 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14714 the AC_CONFIG_COMMANDS invocation.
14715 This also solves the name clash problems.
14716 Don't set the package's ID.
14717 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14718 No longer to be shipped.
14719 (version.in): Remove.
14720 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14721 * lib/autoconf/status.m4: Adjust.
14722 Use `m4_PACKAGE_STRING'.
14723 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14724 the only optional argument is the name of the test suite.
14725 Expect `package.m4' to define the package signature.
14726 * lib/autom4te.in (Autotest): Add `package.m4?'.
14727 * tests/Makefile.am (package.m4): New.
14728 * tests/suite.at: ifnames is a victim.
14730 2001-09-18 Akim Demaille <akim@epita.fr>
14732 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14733 AC_LIBSOURCE, AC_CONFIG_FILES.
14734 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14735 program version string doesn't match the package's.
14736 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14739 2001-09-17 Paul Eggert <eggert@twinsun.com>
14741 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14742 Allow expression to return any value that can fit into unsigned long
14743 (not int, as before). Check for output errors.
14745 2001-09-17 Bruno Haible <haible@ilog.fr>
14747 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14748 Always include <stdio.h> and <stdlib.h>. Evaluate
14749 the expression in an extra function before these includes. Call
14750 fprintf "%d" only after ensuring the argument is of type 'int'.
14751 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14753 2001-09-17 Paul Eggert <eggert@twinsun.com>
14755 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14756 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14757 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14758 when they don't exist.
14760 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14761 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14764 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14765 version with the version used by fileutils 4.1, except use
14766 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14769 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14771 2001-09-13 Akim Demaille <akim@epita.fr>

14795 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14797 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
14798 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
14799 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14800 AT_tests_all for consistency.
14802 (AT_VICTIMS): Similar to AT_KEYWORDS.

14807 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14809 2001-09-13 Akim Demaille <akim@epita.fr>
14811 * lib/autotest/general.m4 (AT_INIT): Create and remove
14812 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14813 test suites can cohabit.
14815 2001-09-13 Akim Demaille <akim@epita.fr>

14926 the maintainer is dumb enough to do that...
14928 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14929 excellence in M4 quotation: consider `__file__' is active.

15109 find the executables for it.

15111 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15113 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15114 indeed related to running the test suite, while passing
15115 --autoconf-dir and others is related to running non installed

15118 * tests/autoscan: New.
15119 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

15138 2001-08-29 Akim Demaille <akim@epita.fr>

15296 (AMTAR): Help automake define it.
15297 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
15298 needed, 1.5 can have a macro and a target with the same name.

15527 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

15545 * doc/autoconf.texi: Work around Texinfo buglets.
15546 (Transformation Rules): One example is enough, users are expected

15552 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15605 autom4te.cache (it's a directory, not a file.
15606 * Makefile.am: Ditto (but maintainer-clean-local).
15608 2001-08-15 Akim Demaille <akim@epita.fr>
15610 * bin/autom4te.in (@m4_warning): New.
15611 (&handle_m4): Use it.
15612 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

15684 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15685 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15686 * doc/autoconf.texi (C Compiler Characteristics): Update
15687 documentation for AC_C_BIGENDIAN.
15689 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15691 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15692 magic values from an object file when cross-compiling.
15693 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15695 2001-08-10 Akim Demaille <akim@epita.fr>
15697 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15699 Suggested by Russ Allbery.
15701 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15703 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15704 current $prefix to the sub-configures.
15706 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15708 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15709 extension (needed on BeOS). Reported by Guido van Rossum.
15711 2001-08-09 Akim Demaille <akim@epita.fr>
15713 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15715 2001-08-07 Akim Demaille <akim@epita.fr>
15717 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15719 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15720 No need to remove the files before and after the each test, before
15721 each test and at the end of the suite is enough.
15722 Display only the children `times', not the shell's.
15723 If the test failed or was skipped, at-times is not available.
15725 2001-08-07 Akim Demaille <akim@epita.fr>
15727 Always produce testsuite.log, including when there are no
15728 failures. This helps getting information on skipped tests, and
15729 duration of the tests. Err, implement the latter btw.
15731 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15732 Dump information on the first run of each test.
15733 (AT_CLEANUP): Create `at-times' containing the duration of the
15736 2001-08-07 Akim Demaille <akim@epita.fr>
15738 The use of `dumpstat' revealed that `len' was used although it
15739 should not. m4_text_wrap was using it, but in the Autoconf world
15740 where it is legal. Hence (i) test M4sh in its own world, not
15741 Autoconf's, and (ii), ahem, fix the bug :)
15743 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15744 does not like `' instead of [].
