1545 (func_sanitize_dir_name): New shell functions.
1546 * tests/tools.at (autom4te and whitespace in file names)
1547 (autotools and whitespace in file names): Use them.
1548 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1549 Cover more potentially problemtic file names. Use the new
1552 Properly handle funny file names for headers in config.status.
1553 The test suite did not cover this bug because the code was not
1554 quoting properly the arguments of `rm -f' (which "fails" silently)
1555 as well as the arguments of `diff' (whose output was redirected to
1556 /dev/null so we couldn't see its error message).
1557 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
1558 file names passed to `rm' and `diff'.
1559 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

1674 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1676 <DEFAULTS>: Delay computation of variables based on $at_dir...
1677 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1678 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1679 <PARSE_ARGS>: Parse new option.
1680 <HELP_TUNING>: Document it.
1681 * tests/autotest.at (Choosing where testsuite is run): New test

1696 * doc/autoconf.texi (Particular Programs): Do not mention the
1697 Autoconf version in which the AC_PROG_INSTALL change was done.

1700 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1702 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1703 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1704 mode, we change to the source directory, also set $ac_pwd so we
1705 do not go back to the build tree for the next config subdir.
1706 * tests/torture.at (Deep Package): Extend test to contain two
1707 config subdirs on the top level.

1768 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1770 Optimize AC_REQUIRE.
1771 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1772 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1773 (m4_require): Avoid extra macro calls.
1775 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1777 * tests/torture.at (srcdir): Fix quoting.
1779 Do not pass top_srcdir to configure scripts in testsuite.

1789 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1790 (Substitute a newline, datarootdir workaround): Likewise.
1791 (Define a newline): Adjust for linenumber changes in configure.ac.

1799 * tests/tools.at (Syntax of the shell scripts): Likewise.
1801 * tests/m4sh.at (LINENO): Quote $0.
1803 Fix testsuite program wrapper for whitespace in `pwd`.
1804 The problem here is that the usual mantra is that command
1805 variables can contain arguments, thus we cannot just escape
1806 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1807 $top_builddir/tests directory early in $PATH, so that the
1808 wrappers are found by their plain name.
1809 * tests/wrapper.as: Put $testdir early in $PATH.
1810 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1812 Proper config.status --file/--header and $srcdir escaping.

1823 Quote $at_group_dir.
1824 * tests/autotest.at (whitespace in absolute testdir): New test.
1826 * lib/autom4te.in: Quote @datadir@.
1828 Proper file name escaping in Autoconf programs and Perl modules.
1829 This includes escaping of characters special to the shell
1830 as well as special to Perl, e.g., leading `<' or `>'.
1831 For example, when $file starts with `>', `open ">$file"'
1832 wrongly tries to append to a different file.
1833 * bin/autoconf.as: Fix quoting for autom4te options.
1834 * lib/Autom4te/General.pm (shell_quote): New function, taken
1835 from coreutils, written by Jim Meyering.

1844 * tests/tools.at (autom4te and whitespace in file names): Extend
1845 test. Test twice, with special characters allowed on w32, and the
1846 rest. Test leading and trailing whitespace, for `open_quote'.
1847 (autotools and whitespace in file names): New, analogous test.
1848 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1849 by Russ Allbery and Eric Blake.

1853 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1854 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1855 (update_file, contents): Use it.
1857 * Makefile.am (autom4te-update): Rewrite for git.
1859 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1861 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1863 Fix copyright years.
1864 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1865 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1867 2007-12-04 Eric Blake <ebb9@byu.net>

1877 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1879 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1880 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1881 #undef as this runs afoul of our new way of creating config.h.
1882 Problem reported by Jim Meyering in
1883 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1899 `#AT_STOP_...' line at the end of each test.
1901 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1903 * lib/autotest/general.m4 (AT_INIT): For awk line number
1904 extraction script, ensure `$at_group' has a defined value
1905 even for the empty set, and properly quote its usage inside
1908 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1910 * doc/autoconf.texi (Shell Functions): New chapter. Document
1911 IRIX sh $0 issue in functions, move content from ...
1912 (Portable Shell): ... here.
1913 (Shell Script Compiler): Note that shell functions are not
1914 totally unportable any more.

1927 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1929 Fix IRIX testsuite debugging failures: $0 in functions.
1930 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1931 Do not use $0 inside a function, as IRIX sh will set that to the
1932 function name rather than the script invocation name.
1934 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1935 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1937 * lib/autotest/general.m4 (at_func_test): Use cached line numbers

1939 (AT_INIT): Extract and cache test script line numbers.
1941 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1943 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1944 subsequent fixups; the awk -> here-document conversion trashes
1945 performance too much with AIX sh.
1947 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1949 * tests/local.at: Do not test m4, perl with AT_TESTED.
1951 Diagnose and guard against write errors dealing with config.status.
1952 The general idea is this: all write failures from `configure'
1953 writing `config.status' are indicated by $ac_write_error, which
1954 is only checked at the end. This is safe because config.status
1955 code is not executed before the file is complete. Other write
1956 failures, be they inside config.status, or in sub shell/awk
1957 scripts spawned from configure or config.status, typically need
1958 earlier checking, as their results are used right afterwards.
1959 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1960 before writing config.status, check afterwards.
1961 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1962 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1963 Set `ac_write_error' for write failures to config.status. Barf
1964 upon write failures to temporary files.
1965 Adjust note about closing and reopening the here-document.
1966 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1967 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1968 reopening the here-document.
1969 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1970 Ensure `ac_write_error' does not escape into config.status.
1971 Also, add a couple of code paths not yet exercised in the test
1972 suite: a config file with input from stdin, and a config header
1974 Suggestion for catching write errors by Bruno Haible.
1976 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1978 Avoid error with Tru64 awk and testsuite lines with many words.
1979 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1980 reads the testsuite, set the field separator to an unusual value,
1981 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1982 even splits the input if $i, i>0, was never accessed in the script.
1984 Revert 2007-10-17 change.
1985 * TODO: Multiline args in config files and headers mean something
1986 different and are not fixed, see

2032 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2035 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2037 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2040 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2042 * lib/autoconf/status.m4: Fix a couple of comment typos.
2044 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2046 2007-11-13 Jim Meyering <meyering@redhat.com>
2048 Clean up the rule to create "expr".
2049 * tests/Makefile.am (expr): Don't redirect directly to target.
2050 Redirect just once, not for each echo statement.
2051 Use $@, not literal "expr".
2053 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2055 Don't worry about preprocessor when testing long long.
2056 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2057 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2058 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2059 These no longer check for preprocessor flaws.
2060 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2061 Do not check for preprocessor flaws.
2063 2007-11-13 Jim Meyering <meyering@redhat.com>
2065 Adapt dependencies, now that a version change doesn't modify configure.ac
2066 * GNUmakefile: Remove "make clean" kludge.
2067 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2069 Don't redirect directly to target.
2070 Use $@, not literal "version.m4".
2072 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2074 * doc/autoconf.texi (Making testsuite Scripts): Document
2075 ":;{" shorthand as in previous patch.
2077 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2079 * doc/autoconf.texi (Limitations of Builtins): Document problem
2080 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2082 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2083 Use ":;{" shorthand.
2084 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2086 2007-11-12 Jim Meyering <meyering@redhat.com>
2088 Add more non-srcdir build support.
2089 * GNUmakefile (dummy): Split a long line.
2090 Add -v option to autoreconf invocation.
2092 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2093 * GNUmakefile (dummy): Remove INSTALL.
2095 Remove racy commands to build scripts in bin/ and tests/.
2096 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2097 are guaranteed to be built, remove the rules that tried to build
2098 them. Before, with a parallel build, these rules could lead to
2099 two processes writing tests/wrapper.in concurrently.
2101 Build in man/ only *after* building in bin/ and tests/.
2102 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2103 in both bin/ and tests/.
2105 Accommodate non-srcdir build-from-checkout.
2106 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2107 Use git's --git-dir=$srcdir/.git option.
2108 Add quotes, in case tarball_version_file contains shell meta-characters.
2109 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2110 * configure.ac: Pass "." to git-version-gen.
2112 Avoid spurious test failures due to version skew.
2113 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2115 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2117 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2118 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2119 Remove conftest.dSYM directory.
2120 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2121 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2122 Remove `conftest.*' recursively.
2123 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2124 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2126 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2128 Report and analysis by Jeff Squyres and Peter O'Gorman.
2130 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2132 Fix typos in variable names.
2133 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2135 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2137 Document that $((expression)) is not portable.
2138 * doc/autoconf.texi (Shell Substitutions): Here.
2140 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2142 Ignore configure --help* errors due to LINENO-impaired shells.
2143 * tests/torture.at (Configuring subdirectories, Deep Package):
2144 In the --help* tests in read-only trees, make `.' temporarily
2145 writable again for the `stderr' file, and ignore errors due to
2146 the attempt to write configure.lineno.
2147 Report by Patrick Welche.
2149 2007-11-10 Jim Meyering <meyering@redhat.com>
2151 Generate package.m4 in build-dir, not srcdir.
2152 * tests/Makefile.am (package.m4): Adjust target.
2153 Don't redirect directly to $@.
2154 (CLEANFILES): Add package.m4.
2155 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2157 When running $(AUTOTEST), search "." before searching $(srcdir).
2159 Avoid a race condition that would make parallel "distclean" fail.
2160 * tests/Makefile.am (distclean-generic): Replace the default,
2161 automake-provided rule with an identical one, but with an additional
2162 dependency on distclean-local. Simply adding the dependency would
2163 cause automake not to emit the rule at all.
2164 * BUGS: Building with -jN works, now.
2166 Distribute git-version-gen.
2167 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2168 since GNUmakefile is distributed, and requires it for dist* rules.
2170 Remove two more generated files from version control.
2171 * INSTALL: Remove generated file.
2172 * lib/autoscan/autoscan.list: Remove generated file.
2174 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2176 * GNUmakefile (PATH): Remove stray apostrophes; they become
2177 part of PATH, which isn't wanted here.
2179 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2181 New config files output variable `top_build_prefix'.
2182 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2184 * doc/autoconf.texi (Preset Output Variables): Document it.
2186 Report by Bob Friesenhahn.
2188 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2189 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2190 function, to parametrize arithmetic with expr vs. the shell.
2191 Use it where possible.
2192 Suggestion by Benoit Sigoure.
2194 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2196 Adjust the documentation of autotest WRT atlocal.
2197 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2198 when using Automake, to write a rule to produce atlocal, since it's
2199 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2200 distributed, not atconfig.in.
2202 2007-11-04 Eric Blake <ebb9@byu.net>
2204 Update list information.
2205 * README: Mention new autoconf-commit list.
2206 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2208 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2210 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2212 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2214 * build-aux/.gitignore: Ignore mkinstalldirs.
2216 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2218 2007-11-03 Jim Meyering <meyering@redhat.com>
2220 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2221 * build-aux/git-version-gen: This syncs from coreutils.
2223 Adjust the build procedure so "make check" works reliably.
2224 * README-hacking: Include an extra step between "make" and
2225 "make check" to ensure that the latter passes.
2227 Use just-built tools, when possible.
2228 * GNUmakefile (PATH): Set and export here, ...
2229 (dummy): ... rather than here.
2231 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2232 and Andreas Schwab <schwab@suse.de>
2234 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2237 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2239 * configure.ac (AC_PREREQ): Require version 2.60, for
2240 AC_PROG_SED, AC_PROG_GREP.
2242 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2243 and Jim Meyering <meyering@redhat.com>
2244 and Andreas Schwab <schwab@suse.de>
2245 and Eric Blake <ebb9@byu.net>
2247 Document a bug in GNU Bash with compound commands and redirections.
2248 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2249 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2252 2007-11-03 Eric Blake <ebb9@byu.net>
2254 Support m4 1.4.5 in testsuite.
2255 * tests/torture.at (Define a newline): Exclude line numbers in
2257 Reported by Ralf Wildenhues.
2259 2007-11-03 Jim Meyering <meyering@redhat.com>
2261 Remove automake-provided files from version control.
2262 * build-aux/elisp-comp: Remove file.
2263 * build-aux/install-sh: Remove file.
2264 * build-aux/missing: Remove file.
2265 * build-aux/mdate-sh: Remove file.
2266 * build-aux/.gitignore: New file.
2267 Suggestion from Ralf Wildenhues.
2269 2007-11-03 Eric Blake <ebb9@byu.net>
2271 Adjust version comparison to account for git snapshot numbers.
2272 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2273 component separator.
2274 * doc/autoconf.texi (Number processing Macros)
2275 <m4_version_compare>: Document this change.
2276 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2278 2007-10-30 Bruno Haible <bruno@clisp.org>
2280 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2281 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2282 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2283 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2284 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2285 Suggested by Paul Eggert.
2287 2007-10-28 Jim Meyering <meyering@redhat.com>
2289 * README-hacking: Autoconf, Automake, and Perl are required to build.
2290 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2292 2007-10-28 Jim Meyering <meyering@redhat.com>
2294 README-hacking: Recommend running autoreconf -vi.
2295 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2296 so that we use just-built tools when they're available.
2297 Suggestions from Ralf Wildenhues.
2299 2007-10-28 Jim Meyering <meyering@redhat.com>
2301 Make inter-release --version output more useful.
2303 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2304 which indicates that it is built using the 19th change set
2305 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2306 is a prefix of the commit SHA1.
2307 * build-aux/git-version-gen: New file.
2308 * configure.ac: Run it to set the version.
2309 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2310 * Makefile.am (dist-hook): Arrange so that .version appears only
2311 in distribution tarballs, never in a checked-out repository.
2312 * .gitignore: Add .version here, too. Just in case.
2313 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2314 not configure.ac, now that the version number changes automatically.
2316 Ensure that $(VERSION) is up to date for dist-related targets.
2317 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2318 git-version-gen doesn't match $(VERSION), but only for dist targets.
2320 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2322 Fix `Deep Package' failure with a configure script early in PATH
2323 * tests/torture.at (Deep Package): Add `.' early in PATH.

2337 Improve corner case of m4_expand.
2338 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

2341 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
2344 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
2346 * doc/make-stds.texi: Update from gnulib.
2348 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2349 and Eric Blake <ebb9@byu.net>

2352 problem reported by Bruno Haible in
2353 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2355 2007-10-22 Eric Blake <ebb9@byu.net>
2357 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2360 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2362 Don't check for bug in HP-UX 11.00 cpp.
2363 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2364 Use -1ull rather than -1u, since that causes problems with gnulib; see
2365 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
2367 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2383 escaping of backslash in here-documents.
2385 Fix `Deep Package' test failure on FreeBSD.

2387 unnecessarily. Do not try running `/bin/sh configure' with a
2388 configure script to be found in $PATH, if the shell does not do
2389 this resolution. Fixes test failure on FreeBSD.
2391 Fix config header generation with AIX awk.
2392 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2393 script, use helper array D_is_set, as `" 0"' does not evaluate
2394 to true for AIX awk.
2396 2007-10-21 Eric Blake <ebb9@byu.net>

2431 * lib/autotest/general.m4 (BANNERS): New named diversion.
2432 (TESTS_END): Diversion no longer used.
2433 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
2434 shell function, which prints only as needed, using an associative
2435 array of banner text from a special diversion.
2436 <PARSE_ARGS_END>: No longer need awk to find banners.
2437 <TESTS>: Banners are no longer processed by main driver loop, so
2438 we no longer need case statement.
2439 (AT_BANNER): Rewrite to populate new diversion.
2440 (AT_SETUP): Each test invokes its own banner. No output is needed
2441 to the TESTS diversion.

2468 duplication bug by using new macro.
2469 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
2470 programs with stdin redirected, so programs that don't
2471 understand --version won't try to behave interactively.
2472 * tests/autotest.at (Tested programs): Catch this bug.
2473 * tests/m4sugar.at (m4@&t@_append): Test new macro.

2534 will not actually be needed. Still try removing files, in case

3534 renamed to "autoconf-invocation"
3536 * doc/autoconf.texi (Caching Results): The CACHE-ID variable
3537 in the examples should not use the internal "ac_" prefix.

3553 section titles and other comments; no code change.
3555 2007-05-01 Kevin Ryde <user42@zip.com.au>
3557 * doc/autoconf.texi (Particular Programs): Typo
3558 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
3560 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
3562 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
3563 'configure' will fail if the shell lacks proper support for shell
3564 functions. Suggested by RMS.
3566 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
3568 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
3569 about Solaris /bin/printf '%010000x' 123. Problem reported by
3572 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
3574 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3575 for a.* when searching for executables, as this prevents users
3576 from having files like a.c. Problem reported by Ralf Wildenhues in:

3588 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3589 AC_CHECK_TYPE, AC_CHECK_TYPES.
3590 * doc/autoconf.texi (Generic types): C types must be type-names
3591 (the C terminology), not type-ids (the C++ term). C++ types
3592 must not be anonymous.
3593 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3594 for C++; this drops support for anonymous struct and union types,
3595 which were problematic anyway.
3596 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3599 2007-04-12 Jim Meyering <jim@meyering.net>

3612 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3613 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3614 with objects too. Document the restrictions on its use.
3615 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3616 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3617 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3618 works but the latter doesn't, then it's a valid type.
3619 This lets people use function types and so forth.
3620 For C++ there doesn't seem to be a simple solution, so leave it alone.
3621 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3622 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3623 AC_CHECK_TYPE; that wasn't documented or necessary.
3625 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3627 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
3628 when cross-compiling.

3675 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3676 nonstandard grep R.E. escape sequences.
3678 2007-03-17 Jim Meyering <jim@meyering.net>
3680 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3681 (Limitations of Usual Tools): Also list \< and \>, and mention that
3682 HP-UX's grep, like the one from Solaris, does not support that syntax.
3684 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3686 * doc/autoconf.texi (Specifying Names): `--host' does not
3687 change the build type.

3724 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3725 status of rm so we know when it failed.
3726 If cleaning of test dir failed before running the test, warn.
3727 Output the line separator in verbose mode before the warning
3728 to make clear the warning belongs to the following test.

3793 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3794 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3795 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3796 substitution will still be done by the special code.

3820 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3821 early on the reader side, drop stderr of the input to avoid
3822 `broken pipe' error output; this may happen even with shell
3823 builtin `echo' of some bash versions. Reports by Ian Macdonald

3840 * doc/autoconf.texi (Signed Overflow Examples): Give more
3841 discussion about the allow_superuser_privileges example,
3842 and change it a bit to make things clearer.
3843 (Optimization and Wraparound): Clarify whether the compiler
3844 will generate an infinite loop for the example derived from
3845 Autoconf's mktime test.
3846 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3847 Also, clarify unsigned multiplication overflow.
3849 2007-01-04 Eric Blake <ebb9@byu.net>
3851 * bin/Makefile.am (RELEASE_YEAR): New macro.

3861 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3863 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3864 feedback. The most important changes document what happens when
3865 you convert an out-of-range value to a signed integer type, and
3866 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3869 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3870 rewrite, taking notions from the recent discussion on the gcc and
3871 autoconf mailing lists; please see
3872 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3873 and follow the many links.
3874 (Integer Overflow Basics, Signed Overflow Examples):

3876 (Signed Integer Division): New sections.
3878 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3880 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3881 preprocessor macro arguments in traced name.
3882 * doc/autoconf.texi (Defining symbols): Document longstanding
3883 support for AC_DEFINE-ing macros with arguments, and document
3884 behavior when the same variable has multiple AC_DEFINEs.
3885 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3886 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3887 macros directly, giving much shorter and simpler code.
3889 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3891 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3892 space before "$ac_configure_args" to prevent a 'config.status
3893 --recheck' failure if ac_configure_args doesn't contain a leading
3894 space. This works around a problem with the XEmacs configure.ac,
3895 which uses the (undocumented) ac_configure_args variable
3896 inconsistently with Autoconf.
3898 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3900 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3901 Include <limits.h>, and use its INT_MAX to rewrite the
3902 j loop so that it does not overflow 'int'. Problem reported by
3904 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3905 Play it safe by shifting left by 1 rather than multiplying by 2,
3906 as GCC is less likely to optimize this away when the value
3907 is signed (when it assumes overflow leads to undefined behavior).
3908 Also, don't assume time_t uses two's complement.
3910 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3912 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3913 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3914 dumps core on it. Report by Tim Rice.

3932 (Configure Option Checking). Tighten up the wording a bit.
3933 (External Software, Package Options): Cross-reference to Option
3934 Checking, and use this to shorten our section.
3935 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3936 "$x" to test "x$foo" != x.
3937 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3938 Don't warn if $enable_option_checking is "no".
3939 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3940 ac_unrecognized_opts to the empty string.
3941 Don't echo the unrecognized opts, as this might mishandle
3942 backslashes or leading -.

3944 usage next to the other --disable-FEATURE options in the

3949 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

3951 Print warning for unrecognized --with and --enable options
3952 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3953 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3954 Disable option checking when subdirs are configured.
3955 (AC_OUTPUT): If warnings are enabled, print warning about
3956 unrecognized --with and --enable options at the end of
3957 the configure output (as well as at the beginning).
3958 * doc/autoconf.texi (Option Checking): New node.
3959 Document new option warning functionality.
3961 2006-12-16 Eric Blake <ebb9@byu.net>

3966 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3968 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3969 Define HAVE_GETMNTENT to 1, not to the empty string.
3970 Problem originally reported by Jochen Friedrich in
3971 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3973 This change prompted by a problem report by Andrey Simonenko in
3974 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3975 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3976 object-like macros only, in the traditional portable character
3978 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3979 Warn about attempts to define things that are not identifiers.
3980 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3981 awful hack that AC_DEFINEd macro names containing parentheses.
3983 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3985 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3986 too drastic, even if Texinfo in theory requires it for info mode.
3988 (config.status Invocation): Renamed back from Recreating a
3990 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3991 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.

3997 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3998 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4000 * NEWS: Document changes with echo and printf, and the lack
4001 of limits on the total size of multi-line values of substituted
4002 variables, and the AC_FUNC_FSEEKO fix.
4004 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4006 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4007 Writing configure.ac.
4008 (Autoconf Input Layout): Renamed from configure.ac Layout.
4009 (Recreating a Configuration): Renamed from config.status Invocation.
4010 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4011 (acconfig Header): Renamed from acconfig.h.
4012 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4013 (Writing Testsuites): Renamed from Writing testsuite.at.
4014 (Autom4te Cache): Renamed from autom4te.cache.
4016 * BUGS: Remove mention of VPATH problem, since it's now documented
4017 not to be a bug in the Autoconf build procedure itself, but rather
4018 a problem with the proprietary `make' programs.
4020 * doc/autoconf.texi (Build Directories): Add a cross reference
4023 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4024 * doc/standards.texi: Sync from gnulib.
4026 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4027 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4028 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4029 generated automatically.
4031 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4033 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4034 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4035 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4037 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4039 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4040 `CEOF$ac_eof' special marker, the awk script cannot contain a
4041 line matching `^CEOF', so this is not needed any more.
4042 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4043 special marker in the test.
4045 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4047 * tests/tools.at (autom4te preselections): Use `find -newer';
4048 remove one of the sleeps.
4050 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4051 more readable, using ...
4052 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4054 * doc/autoconf.texi (autoheader Invocation): Do not double-
4055 quote the parameter of `AH_BOTTOM' in the example.
4057 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4059 * doc/autoconf.texi (Configuration Headers): Remove the
4060 example with multiple input files.
4061 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4062 multiple input files.
4064 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4066 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4067 creating the awk substitution script, handle one input line at a
4068 time, so that the maximum length of a substituted (multi-line)
4069 value is not limited by the size of the sed pattern space.
4070 The trade-off is a slightly repetitive sed script.
4071 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4072 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4073 * tests/torture.at (Substitute a 2000-byte string): Increase the
4074 test with several long lines, they should not be caught by sed
4077 * tests/tools.at (autom4te preselections): New test, to flag
4078 entries missing from autom4te.cfg.
4079 Report by David Byron <dbyron@hheld.com>.
4081 * tests/torture.at (Substitute a 2000-byte string): Actually use
4082 AC_PROG_AWK, so the last change works as intended.
4083 (Substitute and define special characters): Likewise.
4084 (Substitute a newline): Likewise.
4086 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4087 instead of `awk' consistently.
4088 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4089 * tests/torture.at (Torturing config.status): Test both the
4090 result of AC_PROG_AWK and plain awk.
4091 (Substitute a 2000-byte string): Likewise.
4092 (Substitute and define special characters): Likewise.
4093 (Substitute a newline): Likewise.
4095 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4097 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4098 can be assigned to a function pointer. Problem reported by
4099 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4100 part of a patch by Ralf Wildenhues in that same bug report.
4102 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4104 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4105 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4107 2006-12-01 Eric Blake <ebb9@byu.net>
4109 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4110 cross-compiling from cygwin to mingw.
4111 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4112 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4113 to lib/autoconf/c.m4.
4115 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4117 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4118 string for more reliable failure. Wrap the entire test that
4119 causes the broken Solaris printf to dump core, in a subshell,
4120 so the segmentation fault message is reliably suppressed.
4121 Fix shell expansion errors by using /usr/ucb/echo always;
4122 avoid an error on systems without it by another subshell.
4123 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4124 subshell-$as_echo to `as_echo', for better error message.
4126 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4128 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4129 `BASH_SOURCE' contain a newline, set them to empty, as they may
4132 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4134 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4135 years and is too hard to maintain now. The last straw was
4136 reported by Jerker Baeck in
4137 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4138 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4139 * doc/autoconf.texi (Particular Functions): Move
4140 AC_FUNC_SETVBUF_REVERSED from here...
4141 (Obsolete Macros): ... to here. Say that it does nothing now.
4142 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4143 Turn into (almost) a no-op.
4145 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4147 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4148 These macros are obsolescent and new applications shouldn't need them.
4149 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4150 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4151 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4152 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4153 (AC_FUNC_VPRINTF): Likewise.
4154 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4155 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4156 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4158 * doc/autoconf.texi (Setting Output Variables): Mention that
4159 @VAR1@VAR2 has unspecified behavior. Problem reported by
4161 * NEWS: Mention this.
4163 * Makefile.am: Put only a single '#' into the copyright notice,
4164 so that it's also present in the output file. Standardize wording
4165 in makefile copyright notices to match GNU coding standards.
4166 * bin/Makefile.am: Likewise.
4167 * doc/Makefile.am: Likewise.
4168 * lib/Makefile.am: Likewise.
4169 * lib/freeze.mk: Likewise.
4170 * lib/autoconf/Makefile.am: Likewise.
4171 * lib/autoscan/Makefile.am: Likewise.
4172 * lib/autotest/Makefile.am: Likewise.
4173 * lib/m4sugar/Makefile.am: Likewise.
4174 * man/Makefile.am: Likewise.
4175 * tests/Makefile.am: Likewise.
4176 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4179 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4181 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4182 in the sed script that mangles the awk script: delete up to the
4183 first exclamation mark only.
4184 * tests/torture.at (Substitute and define special characters):
4187 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4189 Rewrite config files generation: avoid quadratic growth in
4190 the number of substituted variables by using awk instead of sed
4191 for the bulk of the substitutions.
4192 * NEWS: Mention this.
4193 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4194 forbidden in the output (and thus input) file.
4195 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4196 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4197 generate just one large awk script for substitutions,
4198 eliminating much of the earlier complexity, while adding some
4199 new complexity. Only expand the substitution templates at
4200 configure time, for smaller configure script size. If
4201 _AC_SUBST_FILES are used, test 'awk' for working getline support
4202 at config.status time. If absent, interpolate through the
4203 shell. The awk script was written with much help
4204 from Paolo Bonzini and Paul Eggert.
4205 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4206 (_AC_SED_FRAG_NUM): Likewise.
4207 (_AC_SUBST_CMDS): Renamed from...
4208 (_AC_SED_CMDS): ...this.
4209 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4210 * tests/torture.at (Substitute a 2000-byte string): Also
4211 substitute a line with 1000 words, and a variable with several
4213 (Substitute and define special characters): Test awk special
4214 characters, and put substitution input strings `@foo@' in the
4215 output, to test that no recursion happens; test several other
4216 combinations from Paolo Bonzini.
4218 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4220 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4221 that replaced echo with AS_ECHO where this wasn't necessary.
4222 Problem reportd by Ralf Wildenhues.
4223 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4224 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4225 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4227 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4229 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4231 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4233 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4234 that traditional Awk lacks 3-arg "split". It has it.
4235 Mention that FS must be a single character, and a few other
4236 99-byte limits of traditional Awk.
4237 Mention that if (i in a) doesn't work with traditional Awk.
4239 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4241 * tests/autotest.at (BSx641-newline in command):
4242 (BS-BS-newline in command, BSx640-newline in command):
4243 (Newline-CODE-BS-newline in command):
4244 (Single-quote-BS-newline in command):
4245 (Single-quote-newline-BS-newline in command):
4246 Use printf '%s\n' instead of echo, for portability to hosts
4247 where echo interprets backslashes. This will break on hosts
4248 that lack printf, but for now let's assume all such hosts
4249 are dead (if not, we should get reports of test failures).
4251 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4253 'echo' has some portability problems, when given a first argument
4254 with a leading '-', or when given any argument containing '\'.
4255 Avoid using 'echo' in these cases.
4256 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4257 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4258 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4259 * lib/autotest/general.m4 (AT_INIT): Likewise.
4260 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4261 argument might be unportable.
4262 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
4263 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
4264 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
4265 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
4266 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
4267 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
4268 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
4269 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
4270 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
4271 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
4272 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
4273 (AC_PROG_MAKE_SET): Likewise.
4274 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
4275 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
4276 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
4277 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
4278 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
4279 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
4280 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4281 * bin/autoconf.as: Redo verbose flag implementation, as the old
4282 scheme wouldn't work with AS_ECHO.
4283 * lib/autotest/general.m4 (AT_INIT): Likewise.
4284 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4285 Don't use ECHO_T, since ECHO_N is now reliable.
4286 * lib/autotest/general.m4 (AT_INIT): Likewise.
4287 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4288 rather than using a here-document to put the script into a file.
4289 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4291 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4292 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4293 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4294 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4295 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4296 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4297 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4298 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4299 operand, as AS_ECHO requires. Avoid double file name expansion.
4300 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4301 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4302 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4303 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4304 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4305 Double-quote strings that would otherwise contain M4 comments.
4306 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4308 * configure.ac (AC_INIT): Bump to 2.61a.
4311 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4315 * configure.ac (AC_INIT): Bump to 2.61.
4318 * tests/autotest.at (Macro with backslash in a test title):
4319 Comment out for now, as this tests neither fails nor passes
4320 reliably. Problem reported by Ralf Wildenhues.
4322 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4324 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4325 in previous change, which caused test failures.
4327 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4329 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4330 code for --enable, --disable, --with, and --without to...
4331 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4332 * doc/autoconf.texi (Package Options):
4333 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4335 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4337 Import these changes from config via gnulib:

4394 first argument may also contain dots.
4396 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4398 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4399 benefit of platforms like Solaris+GCC where it is common to have a
4400 non-working g++ installation.

4407 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4410 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4412 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4413 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4414 Imported from a similar patch to gnulib by Bruno Haible.
4416 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4418 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
4419 * doc/autoconf.texi (C Compiler): Document them.
4420 * lib/autoconf/c.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS):

4431 * tests/torture.at (Configuring subdirectories): Do not skip
4432 Automake 1.10 nor future Automake 11.1 (sic).
4434 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4435 and Stepan Kasal <kasal@ucw.cz>
4437 Handle special characters in test case titles correctly.
4438 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4440 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4441 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST

4446 Double-quote in a test title): Don't expect failure anymore.
4447 (Backslash in a test title): Put a non-whitespace character after the
4448 backslash so that Bourne shells might actually see it as an escape
4450 (Brackets in a test title,

4456 (Macro with backquote in a test title,
4457 Macro with double-quote in a test title,
4458 Macro with backslash in a test title): New tests expected to fail.
4459 * tests/torture.at (#define header templates): M4-quote this title in
4460 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4461 The visible effect was a stray [] in the testsuite output.
4463 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4465 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4466 `trap ... 0' inside a function, for AIX sh.
4468 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4470 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4471 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4472 5363) simply issues a warning when dividing by zero at compile
4473 time. Problem reported by Elias Pipping.
4475 2006-10-26 Eric Blake <ebb9@byu.net>
4478 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4479 show effect on macros that expand with commas.

4504 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4506 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4507 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4508 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4509 reported by Nelson H. F. Beebe for Coreutils 6.4.
4511 * tests/tools.at (autoconf --trace: user macros): Remove test
4512 for tracing multiline macros, since m4 1.4.7a uses a different
4513 way to number lines. Problem reported by Ralf Wildenhues.
4515 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4517 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4518 /dev/null since the heuristics for interactive behaviour was

4540 * doc/autoconf.texi (Caching Results): Likewise.
4541 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4542 AC_CACHE_CHECK_INT, since it's no longer public.
4543 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4544 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4589 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4591 (Imported from Automake.)
4592 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4593 which incorrectly sets the mode of an existing destination
4594 directory. In some cases the unpatched install-sh could do the
4595 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4596 system. We hope this is rare in practice, but it's clearly worth
4597 fixing. Problem reported by Alex Unleashed in
4598 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4599 Also, don't bother to check for -m bugs unless we're using -m;
4600 suggested by Stepan Kasal.

4622 2006-09-16 Karl Berry <karl@gnu.org>
4623 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4624 to avoid sectioning errors.

4628 2006-10-04 Karl Berry <karl@gnu.org>
4629 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

4646 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4648 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4649 added to the template can get mangled.
4651 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4653 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4654 include the default headers, and redefine obstack_chunk_alloc
4655 and obstack_chunk_free. Fixes false failure with glibc.
4657 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4659 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

4672 the NonStop platform.
4673 * doc/autoconf.texi (Posix Variants): Likewise.
4674 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4676 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4677 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4678 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4679 Use a better substitute, by inspecting the output of "ls"
4680 rather than just using ":".
4681 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4682 rather than AS_EXECUTABLE_P, since we needn't worry about
4683 non-regular files here.
4685 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4686 due to configuration hassles with this. See Tonya Underwood's report
4687 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4698 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4699 initialization which is not inherited through the environment
4700 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4701 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

4706 problems with mkdir -p -m.
4708 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4710 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4711 comment about ac_cpp_err; it was incorrect, and anyway
4712 ac_cpp_err is being removed below.
4713 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4714 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4715 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4717 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4718 with werror_flag and conftest.err and so forth. This is more
4719 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4720 and anyway the user shouldn't normally want to see this gorp logged.
4721 Problem reported by Ralf Wildenhues.
4722 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4723 empty, not 'no', since the rest of the code uses 'test -z'.
4725 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4727 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4728 Use a single call to AC_DO_TOKENS rather than multiple, for
4730 (_AC_LINK_IFELSE): Test that resulting file is executable.
4731 Problem reported by mwoehlke in
4732 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4734 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4735 than creating a file to use with test -x; this is much faster.
4737 2006-10-02 Bruno Haible <bruno@clisp.org>
4739 * lib/autom4te.in (Automake-preselections): Add
4740 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4742 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4744 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4745 standard error, `experr' should be used, not `expout'.
4747 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4749 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4750 fseeko testing program twice; just use the earlier result.
4751 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4752 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4753 still doesn't let the program compile.
4754 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4757 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4758 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4759 include it, without including anything else.
4760 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4762 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4764 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4766 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4767 `error.h', and include it, for a `error_at_line' prototype.
4768 Use a nonempty format string in the link test.
4769 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4770 for a declaration of wait3.

4776 can apply to constants too, and that it checks for macro defns.
4777 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4778 and simply cast the identifier to void. This handles structure
4779 values. Problem reported by Ralf Wildenhues.

4937 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
4939 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
4940 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
4941 except the first two arguments are reversed.
4942 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
4943 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
4944 caches nor outputs a diagnostic. Suggested by Bruno Haible.

4993 didn't work if some values were cached but not others. Test for
4994 broken lex libraries like native ia64-hp-hpux11.22; see
4995 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4996 work around the problem by preferring an empty LEXLIB to -lfl or
4997 -ll. Let the user set LEXLIB='' to indicate no library needed.

5149 problems with arg script text that doesn't end in newline, and

5201 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5203 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

5227 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5228 more globally, since the 2006-06-30 patch didn't suffice. Problem
5229 reported by Keith Marshall. Also, don't bother with builddir2,
5230 since it shouldn't be needed any more.
5232 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

5251 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5253 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5254 Require that long long int be at least 64 bits wide. C99 requires
5255 this and enough programs depend on it so we should check for it.
5256 Bruno Haible reports in

5269 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5271 * doc/autoconf.texi: Be more consistent about using @acronym with
5272 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5273 quite right (it talked about "OSF/Tru64", even though the
5274 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5275 and it even mentioned "OSF 4"!) and at this point there's little
5276 reason to talk about OSF any more, since it died in 1994.
5277 (Specific Compiler Characteristics): Simplify example of
5278 negative-size array.
5279 (File Descriptors): Reorder to make the text flow better.
5280 Remove joke about "appreciate the various levels"; I didn't get it.

5282 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5283 (File Descriptors, Limitations of Usual Tools):
5284 Tone down the advice against renaming or removing open files.
5285 (Limitations of Usual Tools): Add a new section, on 'rm'.
5287 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5289 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5290 -lXt in LIBS, idea from Karsten Hopp; this was due since
5293 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5294 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5295 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5296 (which belong to Xt, not X itself). See Debian bug 327655.
5298 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5300 * configure.ac (AC_INIT): Bump to 2.60a.

5323 to document the whole `datarootdir' business a bit better.
5325 * tests/torture.at (datarootdir workaround): Extend test.
5326 Prompted by report by Alexandre Julliard.
5328 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5330 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5331 when using default mode of IBM C 6 for AIX. Problem and two-line
5332 fix reported by Larry Jones.
5334 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5336 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5337 about literal '${datarootdir}' if a definition is found in the
5340 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5342 * NEWS: Use "M4" rather than "m4" when appropriate.
5343 Problem reported by Eric Blake.
5344 * doc/autoconf.texi: Likewise.
5345 Use @acronym around BSD, GCC, and GNU when appropriate.
5346 (Why GNU M4): Renamed from "Why GNU m4".
5347 (Redefined M4 Macros): Mention that Posix
5348 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.

5352 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5354 * bin/autom4te.in (handle_output): Do not forbid the empty
5356 * tests/tools.at (autoconf: the empty token): New test.
5358 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5360 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5361 calls, so that we do not care whether they are LIFO or FIFO;
5362 in the m4_wrap, do not check which diversion is the topmost
5363 one, just check that the stack is balanced at the end.
5364 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5365 base diversion forever--pop the previous diversion before
5366 opening the new one; consequently, remove the m4_wrap call.
5367 * lib/autotest/general.m4 (AT_INIT): Likewise.
5368 * tests/m4sugar.at: Do not use
5369 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

5376 Rework example of m4wrap token-pasting trouble so that it doesn't
5377 care whether it's LIFO or FIFO.
5378 Fix some "contrary to"s that are awkward in English.
5380 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5382 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5383 to `yes' instead of `int$1_t' if the type is found, for more
5384 consistent configure output (where $1 is the number of bits).
5385 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5386 Suggested by Bruno Haible.
5388 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5389 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5390 with system headers. Report by Bruno Haible.
5392 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5394 * config/config.guess, config/config.sub: Sync from upstream.
5396 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5397 in order to avoid picking up an older installed frozen m4sh.m4f.
5398 Besides an outdated shell startup, this could have been created
5399 by an earlier M4 version with incompatible frozen file format.
5401 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5403 * README: Recommend m4 1.4.4 instead of 1.4.3..
5404 * doc/autoconf.texi: Likewise.
5405 (Special Chars in Names): Say that $(.FOO) is portable, as
5406 suggested by Stepan Kasal.
5407 (Installation Directory Variables, Build Directories):
5408 (Automatic Remaking, Subdirectories, Fortran Compiler):
5409 (Making testsuite Scripts, Defining Directories):
5410 Quote variable usages better.
5411 (Making testsuite Scripts): Add clean-local rule to makefile
5412 snippet, by Eric Blake.
5413 (Installation Directory Variables): Fix table item font.
5414 Reword slightly to clarify. Generalize advice about
5415 not using special characters to include all file-related
5416 vars, not just VPATH.
5417 (Special Chars in Variables): Warn about special characters in
5419 (Assignments): Clarify default-value example as suggested by
5421 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5422 (Special Shell Variables): Note leading ./ or ../, as suggested
5424 (Limitations of Builtins): Under cd, warn about CDPATH.
5425 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5428 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5430 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5431 `@var', for texi2html.
5432 (Systemology): Some more word wrapping, for DVI output.
5433 (autom4te Invocation): The short option for `--melt' is `-M',
5436 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5438 * doc/autoconf.texi: More formatting and English tweaks,
5439 many suggested by Ralf Wildenhues.
5440 Reword to avoid "@code{...}'s" and the like, since it's ugly
5441 with Emacs info mode. discontents -> woes.
5442 Put a few "will"s back. time stamp -> timestamp.
5443 side-effect -> side effect.
5445 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5447 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5448 Warn about $@ not persisting. Problem reported by Julien Danjou in
5449 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5450 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5451 Mention other special chars, too.
5453 2006-06-14 Eric Blake <ebb9@byu.net>
5455 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5457 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5459 * doc/autoconf.texi: Some systematic minor improvements, as
5460 follows. Use "makefile" when talking about makefiles
5461 generally (which might be named "makefile" or "Makefile" or even
5462 "foo.mk"), "Makefile" when talking about a specific makefile
5463 called "Makefile". This unclutters the text from weird quotes
5464 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5465 values" rather than "@var{foo}s" and similar constructs containing
5466 "}s". Use "Make rules" rather than "Makefile rules". Minor
5467 English-language improvements. Change the prefix "sub-" to "sub"
5469 Put blank lines around examples more consistently.
5470 Avoid "rather" and "very" as intensifiers.
5471 Avoid "will" as an auxiliary.
5472 (Limitations of Make): Split this node into....
5473 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5474 (Leading _ in Macro Names, Backslash-Newline-Newline):
5475 (Backslash-Newline Comments, Long Lines in Makefiles):
5476 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5477 (obj/ and Make, make -k Status, VPATH and Make):
5478 (VPATH and Double-colon, $< in Explicit Rules):
5479 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5480 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5481 New nodes, resulting from splitup of Limitations of Make.
5482 All cross-references changed. Raise the top node from
5483 a section to a chapter, and all subnodes accordingly.
5484 Redo the introductory wording to match the new organization.
5485 (Installation Directory Variables): Use an example that is
5486 closer to what Autoconf actually does. Mention that VPATH's
5487 value should not contain metacharacters or white space.
5488 (Fortran Compiler): Fix a VPATH bug in an example.
5489 (Leading _ in Macro Names): Mention that this problem is no longer
5490 of practical concern.
5491 (VPATH and Make): Reword the advice to make it clearer
5492 that Autoconf and Automake support VPATH in non-GNU make, but
5493 many packages have bugs in this area.
5494 ($< in Explicit Rules): Refer to Build Directories rather
5495 than using a (non-VPATH-safe) example.
5496 (Automatic Rule Rewriting): Mention the sort of disaster that
5497 can ensue with Solaris-style rule rewriting with VPATH.
5499 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5501 * doc/install.texi (Compilers and Options): Weaken the
5502 suggestion to use GNU make for VPATH builds.
5504 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5505 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5507 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5508 in regular expression.
5510 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5512 * doc/autoconf.texi (Installation Directory Variables):
5513 Drop extra @samp from `@table @samp' item.
5514 (Limitations of Usual Tools): Comment fix.
5515 Do not nest @samp just to point to other table items.
5516 (Writing testsuite.at) <AT_CHECK>: The second argument to
5517 `@dvar' is already @samp'ed.
5518 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5519 do not use @var in the second argument.
5521 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5523 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5524 $as_shell.exe too. Problem reported by Andreas Buening in
5525 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5527 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5529 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5530 `unused variable' compiler warning, for `-Wall -Werror'.
5531 Reported by Jaap Haitsma in
5532 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5534 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5536 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5537 case the compiler dumps core. Problem reported for
5538 OpenServer 5.0.7 by Tim Rice in
5539 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5540 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5543 2006-06-06 Tim Rice <tim@multitalents.net>.
5545 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5546 "ERROR" only shows up in "make check" output if there is an
5549 2006-06-06 Eric Blake <ebb9@byu.net>
5551 * tests/tools.at (automatically allowed tokens): Fix typo.
5553 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5555 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5557 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5558 typically overflows on x86 CPUs, even though the C standard
5561 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5563 * configure.ac (AC_INIT): Bump to 2.59e.
5566 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5570 * config/texinfo.tex: Sync from upstream.
5572 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5573 seen, invoke libtoolize with `--ltdl' argument.
5574 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5576 Suggested by Eric Blake.
5578 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5580 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5581 reported by Ralf Wildenhues.

5588 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5590 * doc/autoconf.texi: Modernize some of the references to Solaris.
5592 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5594 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5595 message issued by AC_REQUIRE.
5596 * tests/m4sugar.at: Check m4_require's error message.
5597 * tests/base.at: Check AC_REQUIRE's error message.
5598 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5600 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5602 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5603 `expout' as the last parameter.
5604 * tests/tools.at: Adapt to the above change.
5606 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5608 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5609 information about race-free implementations of mkdir.

5618 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5620 * NEWS: GNU make now recommended for VPATH builds.
5621 Mention that some macros are now documented to be obsolescent.
5622 * doc/autoconf.texi:
5623 Prefer "current" to "modern" to describe
5624 currently-used (albeit perhaps old-fashioned) hosts.
5625 Mention which ancient features no longer need to be worried about.
5626 setgid -> set-group-ID
5627 setuid -> set-user-ID (these are the Posix terms)
5628 Fix some misuses of "only".
5629 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5630 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5631 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

5638 Mention that these macros are obsolescent.
5639 (Installation Directory Variables): shall -> should
5640 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5641 Mention that it's now safe to use 3 and 4.
5642 (Limitations of Usual Tools): cp -r is now specified by Posix.
5643 Omit longwinded and obsolescent discussion of cp -f.
5644 Modernize discussion of expr, ls.
5645 (Limitations of Make): Modernize discussion of VPATH builds.
5646 Mention $? as a workaround in some cases.
5647 * doc/install.texi (Basic Installation):
5648 Mention "./configure; make; make install" first. Be more
5649 specific about why this file is generic. Remove unnecessary
5650 parens. Remove misleading "only". Remove obsolete advice
5651 about csh. Don't say "configure" takes awhile; say it
5652 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5653 and CC=c99 rather than CC=c89, as these are blessed by current
5654 Posix. Recommend GNU make if doing a VPATH build.
5656 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5658 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5659 examples involving shell prompts.

5662 and Paul Eggert <eggert@cs.ucla.edu>
5664 * doc/autoconf.texi (Here-Documents): Add details about the
5665 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5666 use "here-documents" instead of "here documents".

5675 anywhere in directory names.
5677 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5679 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5680 about quoting the case statement, just in case.
5681 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5682 was fixed in ksh93g; reported by Ralf Wildenhues.
5684 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5686 * doc/autoconf.texi (System Services): Do not document

5696 argument with leading hyphen. Problem reported by Paul Eggert.
5698 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5700 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5701 about quoting ac_try: quote all of it, if any of it seems suspicious.
5702 This means we don't have to worry about ${ or sed any more.
5703 Also, double-quote the case statement, to work around misuses via
5704 underquoting as reported by Ralf Wildenhues in
5705 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5706 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5707 undocumented and dangerous macro.

5721 Problem reported by Ralf Wildenhues in
5722 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5723 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5724 pre-2006-05-26 definitions, but leave in the comments that
5725 these macros are dangerous and should not be used.
5726 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5727 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5728 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5729 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5730 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5732 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5734 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5735 the use of 'tr', since this is our only use of 'tr'.
5737 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5738 and Paul Eggert <eggert@cs.ucla.edu>
5740 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5741 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5743 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5745 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5746 the output file in the `${datarootdir}' test.
5748 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5749 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5751 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5752 mention of `datarootdir' in the input file(s), but literal
5753 `${datarootdir}' in the output file, and we haven't warned yet,
5754 then warn as well: the user may have (erroneously) used
5755 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5756 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5757 * tests/torture.at (datarootdir workaround): Extend this test.
5760 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5761 and Paul Eggert <eggert@cs.ucla.edu>
5763 * doc/autoconf.texi (autoheader Invocation): The first argument to
5764 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5765 alternatives and clear up the language a bit.
5767 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5769 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5770 ac_config_guess, ac_config_sub, ac_configure.
5771 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5772 Fix typo that prevented an unnecessary space from being removed.
5773 Problems reported by Ralf Wildenhues in:
5774 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5776 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5778 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5779 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5780 Don't use the term "thread-safe" to talk about mkdir race
5781 conditions, since the problem is more a process than a thread
5782 issue. Problem reported by Stepan Kasal in:
5783 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5784 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5785 the test for 'install' more closely. Look at MKDIR_P first.
5786 Look in the PATH, and at /opt/sfw/bin.
5787 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5788 Don't bother to try mkdir -p, since we already check mkdir --version;
5789 just look at the version number. (There's no easy way to check
5790 for race-free implementations.)
5791 * tests/tools.at (autoconf: subdirectories): Adjust to above
5792 changes, since MKDIR_P now might end in "/mkdir -p".
5794 * doc/autoconf.texi (autoheader Invocation): Mention that the
5795 first arg of AC_DEFINE_UNQUOTED must be a literal.
5796 Problem reported by Ben Pfaff in
5797 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5799 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5800 * doc/autoconf.texi (Special Chars in Variables): New section.
5801 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5802 (Installation Directory Variables): Quote $(datadir) better.
5803 (Limitations of Builtins): Describe some of eval's trickiness.
5805 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5806 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5807 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5808 in front of every arg, not just trailing args. Quote apostrophes.
5809 (_AC_EVAL_ECHO): New macro.
5810 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5811 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5813 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5814 exposed by quoting of eval argument. Put the command on line line
5816 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5817 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5818 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5819 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5820 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5821 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5822 Use eval more safely.
5823 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5824 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5826 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5827 lines, exposed by quoting of eval argument.
5829 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5830 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5832 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5833 initialization of `ac_cv_exeext', do not override it if it was
5834 already set, unless it was set to `no', for compatibility with
5835 Autoconf-2.13, and comment this.
5836 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5837 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5838 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5839 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5840 Document that this test may be overridden by setting
5843 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5845 Revert these two patches:
5847 2006-04-06 Eric Blake <ebb9@byu.net>
5848 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5849 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5852 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5853 Clean up _AC_COMPILER_EXEEXT* macros.
5854 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5855 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5856 ac_file to the name of the default output file and call
5857 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5858 initial `rm' of the candidate files...
5859 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5860 the same list in subsequent `rm' calls, and for the temporary
5861 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5862 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5863 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5864 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5865 no longer needed) by libtool. Make it a cache check.
5866 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5867 copied here by mistake.
5868 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5869 _AC_COMPILER_EXEEXT.
5870 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5871 _AC_COMPILER_OBJEXT directly.
5872 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5874 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5876 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5877 Fix description of how the buggy `sed' works.
5879 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5883 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5884 ENOLCK. Only mention `make -j' when applicable. Only raise
5885 fatal errors when `make -j' is involved. Improve error message.
5887 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5889 * doc/autoconf.texi (Here-Documents): We now know more about
5890 the variable expansion in here documents bug.
5891 Thanks to Tim Rice and Stepan Kasal.
5893 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5894 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5896 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5898 * tests/autotest.at (Multiline command from M4 expansion):
5899 No failure to be expected if the shell quotes newlines in
5900 commands in the `set -x' output. Report by Tim Rice.
5903 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5905 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5906 expansion in the here-documents used by config.status, as that
5907 runs afoul of the Korn shell version M-12/28/93d bug described in
5908 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5909 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5910 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5912 2006-05-23 Jim Meyering <jim@meyering.net>
5914 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5915 Fix typo introduced with 2006-04-02 change. It reversed the sense
5918 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5920 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5921 ac_dB slightly, to save bytes in the script.
5922 Max out at 50 lines, rather than 96; this is more likely
5923 (though not guaranteed) to avoid obscure 'sed' failures.
5925 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5927 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5928 `tr -d -' as bad option argument. Work around this by deleting
5929 an unrelated character.
5930 Report by Tim Rice <tim@multitalents.net>.
5932 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5933 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5934 Stepan Kasal <kasal@ucw.cz>
5936 * doc/autoconf.texi (Particular Programs): Do not promise that
5937 we always prefer the GNU version of the program, and that we
5938 search according to PATH; both rules can have exceptions.
5939 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5940 AC_PROG_SED. Move descriptions of limitations
5941 to the Limitations of Usual Tools section.
5942 (Limitations of Usual Tools) <sed>: Mention script length
5943 limitations with Solaris /usr/ucb/sed.
5944 <grep>: Fix wording for empty alternative. Mention that -c and
5945 -l should not be combined, and that -E and -F should not be
5948 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5949 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5951 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5952 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5954 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5956 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5957 AC_DEFINE is now passed to m4_pattern_allow.
5958 * NEWS: Mention that; likewise for AC_SUBST.
5959 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5960 the parameter to m4_pattern_allow.
5961 * tests/tools.at: Add a check for that.
5963 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5965 * lib/autoconf/status.m4: Fix typos.
5967 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5969 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5970 only the files that this macro generates.
5972 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5974 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5975 the HP-UX sed limitation of 99 commands, labels do not count.
5976 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5978 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5980 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5982 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5983 Import the following fix from coreutils:
5985 2006-01-13 Jim Meyering <jim@meyering.net>
5987 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5988 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5989 not double-quote uses of that variable, to accommodate the rare
5990 case in which getmntent is available in none of the libraries
5991 checked. This happens at least on FreeBSD 5.0.
5993 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5995 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5996 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5997 some other programs unwisely rely on these undocumented vars.
5998 But put in warning comments about them.
5999 Problem reported by Ralf Wildenhues in
6000 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6001 * NEWS: Document that these variables are intended to go away.
6003 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6005 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6006 and set the language to C++ (analogous to the equivalent Fortran
6009 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6010 * doc/autoconf.texi (C++ Compiler): Document it.
6011 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6014 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6016 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6017 that caused config.status to generate 100-command sed scripts; the
6018 portable limit is 99.
6020 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6022 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6023 variable `ac_d' instead of `d' to avoid infringing namespace.
6024 Report by Ralf Menzel.
6026 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6028 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6029 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6030 * tests/tools.at (autoconf: subdirectories): New test, taken from
6031 the corresponding problem report by Ralf Wildenhues in:
6032 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6034 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6035 Quote some uses of shell variables if they might suffer unexpected
6036 globbing. This doesn't fix all instances of quoting problems that
6037 I found, just the easy ones that look safe.
6038 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6039 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6040 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6041 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6042 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6043 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6044 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6046 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6047 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6049 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6051 * bin/autoreconf.in ($help): Reword according to the manual.
6052 Suggested by Olly Betts.
6054 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6055 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6057 * bin/autoreconf.in: Pass the directory argument to
6058 `require_configure_ac'. Fix comment.
6059 * tests/torture.at (Configuring subdirectories): Expose this.
6060 Reported by Olly Betts.
6062 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6064 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6065 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6066 Automake as follows:
6068 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6069 `$configure_in' instead of `configure.in', to preserve
6070 directory component.
6072 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6074 * config/config.guess, config/config.sub, config/texinfo.tex,
6075 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6077 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6079 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6080 test for C99 conformance; (bool) 0.5 is an integer constant
6081 expression, but (bool) -0.5 is not. Problem reported by Fedor
6082 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6084 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6086 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6087 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6088 Warn about obsolete install-sh files. Remove stray sentence
6089 fragment and fix cross reference.
6090 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6091 install -d; this undoes the 2006-05-10 change.
6092 (MKDIR_P): Mark with AN_MAKEVAR.
6093 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6094 that we don't require $INSTALL to be thread-safe. Move comments
6095 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6096 of AC_PROG_INSTALL. Output a message saying that we're checking
6097 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6098 MKDIR_P instead of AC_SUBST.
6099 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6100 Special magic for MKDIR_P, too.
6101 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6103 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6105 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6107 Sync from Automake, as follows:
6109 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6110 * config/install-sh: Initialize IFS, so field splitting isn't
6112 * config/mkinstalldirs: Likewise.
6113 * config/missing: Remove superfluous quotes. Replace all uses of
6114 `[' by `test', for consistency, and for..
6115 * config/missing (sed_minuso, sed_output): New variables.
6116 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6117 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6118 Fixes `missing' to detect `--output' for help2man. Fixes
6119 PR automake/483. Report by Dennis J. Linse.
6120 (autom4te): Document in `missing --help'.
6122 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6124 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6125 * config/install-sh: Don't use 'path' to talk about file names,
6126 as per GNU coding standards. Close a race condition reported by Ralf
6127 Wildenhues and Stepan Kasal. There is still a race condition
6128 on hosts that predate Posix 1003.1-1992, but we can't help this.
6129 Don't mishandle weird characters like space on pre-Posix hosts.
6130 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6131 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6132 AC_PROG_MKDIR_P from AS_MKDIR_P.
6133 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6134 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6135 earlier editions are not (including Automake 1.8.3).
6136 Do not suggest mkinstalldirs for thread-safety.
6137 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6138 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6139 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6140 presence of special characters and race conditions.
6141 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6142 in Autoconf's name space.
6144 2006-05-10 Bruno Haible <bruno@clisp.org>
6145 and Paul Eggert <eggert@cs.ucla.edu>
6147 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6148 from Automake with minor changes.
6149 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6151 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6153 * config/install-sh: Update to Automake CVS version, as follows:
6154 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6155 * lib/install-sh: Simplify the expr implementation of dirname.
6156 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6157 * lib/install-sh: Handle --, and diagnose unknown options.
6159 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6161 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6162 `./autom4te' to create `./testsuite', since the `all' target
6163 will ensure its presence, but `installcheck' should not create
6164 the uninstalled wrappers.
6166 * tests/torture.at (Unusual Automake input files): Skip if we
6167 detect automake < 1.8.
6169 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6171 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6172 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6173 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6176 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6178 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6179 munge (multiple) white space and other oddities.
6180 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6181 single quotes in variable assignment.
6182 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6183 and similar failures by adding multiple spaces, tabs, and other
6185 Report and different test suggested by Francesco Romani
6186 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6188 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6189 single quotes, we only need to search for single quotes; this
6190 both simplifies the search pattern, and makes us less
6191 susceptible to `echo' variations for arguments not containing
6193 (_AC_ARG_VAR_VALIDATE): Likewise.
6195 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6197 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6198 `$*' and IFS concatenation issue with traditional shells and
6199 bash-2.04. Report by Seanster@Seanster.com.
6201 2006-05-03 Bruno Haible <bruno@clisp.org>
6203 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6204 precisely which Mac OS X versions have the od problem.
6206 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6208 * doc/autoconf.texi: Use @option systematically.
6210 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6211 and Bruno Haible <bruno@clisp.org>
6213 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6215 (Integer Overflow): Mention the special case of integer division
6218 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6220 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6221 traditional shells like the Solaris one that do not use the
6222 first IFS character for assembling `$*'.
6223 Prompted by a related report from autoconf_bug@nro.ca.
6225 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6226 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6228 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6229 Mention more problems with the -e option.
6231 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6234 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6236 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6237 in URLs to improve DVI formatted output (requires texinfo 4.6).
6238 (System Services, Systemology, Shellology): Likewise.
6239 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6242 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6244 (Runtime): Fix macro argument names to match description:
6245 `action-if-found' -> `action-if-true' and similarly.
6246 (Obsolete Macros): Likewise.
6247 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6248 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6249 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6251 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6253 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6256 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6259 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6261 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6262 /bin/sh set unsorted output.
6263 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

6268 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
6269 (Integer Overflow, Null Pointers, Buffer Overruns):
6270 (Floating Point Portability, Exiting Portably): New sections.
6271 (Writing Test Programs): Fix some langauge. Recommend exiting
6272 with status 1, not merely nonzero. Clarify exit declaration.
6273 (Run Time): Move C exit status stuff to new Exiting Portably section.

6275 (Portable Shell): Mention the Posix shell.
6277 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6279 * bin/autoconf.as (me): Replace by as_me.
6281 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6283 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6284 since as_me isn't set yet.
6286 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6288 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6289 a few minor bugs in this area.
6291 * doc/autoconf.texi (Programming in M4sh): Comment out the
6292 documentation of AS_BASENAME, for now.
6293 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6294 (Limitations of Builtins) <basename>: Do not refer to
6296 * bin/autoconf.as (me): Don't use AS_BASENAME.
6297 (dir): Remove the unused variable.
6298 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6299 AS_DETECT_REQUIRED. All uses changed.
6300 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6302 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6303 (AS_BASENAME): Use "basename --" to protect against leading "-".
6304 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
6305 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6306 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6307 (_AS_DIRNAME_PREPARE): Likewise.
6308 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6309 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6310 (AS_DIRNAME): Use "dirname --".
6312 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6314 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6315 of "run time" and "run-time" changed to "runtime", for consistency.
6316 * lib/autoconf/fortran.m4: Likewise (in comment).
6317 * lib/autoconf/functions.m4: Likewise.
6318 * lib/autoconf/general.m4: Likewise.
6319 * lib/autoconf/headers.m4: Likewise.
6321 * doc/autoconf.texi (Run Time): Document the exit status situation
6322 with more accuracy and detail.
6324 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6326 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6327 Archive is not officially `GNU' any more. Update URL.
6328 (Defining Directories): Likewise
6329 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6331 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6333 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6334 newline from the `trap' code to finish `config.log'; the NetBSD
6335 /bin/sh resets the exit status after an empty command, as
6336 documented in doc/autoconf.texi.
6337 Reported by Dalibor Topic <robilad@kaffe.org>.
6339 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6341 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6342 Suggested by Bruno Haible.
6344 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6346 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6347 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6348 Instead, just list the shells that we know work.
6349 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6350 changed. Be more cautious about the _cv_ variable.
6351 * tests/tools.at (Syntax of the shell scripts): Check the
6352 _cv_ variable once, at first, to avoid an internal autoconf error
6353 when sh -n does not work.
6355 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6357 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6359 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6361 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6362 use ">&-" since we're only 99.999% sure that this is portable,
6363 and since the MinGW bug is fixed in a different way.
6364 * lib/autotest/general.m4 (AT_INIT): Likewise.
6366 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6368 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6369 before opening config.log, to avoid hitting a bug on MinGW.
6371 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6373 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6374 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6375 This works around a MinGW bug reported by Eric Paire.
6376 Make sure that all writes to the log file append to it,
6377 rather than possibly losing data.
6378 * lib/autotest/general.m4 (AT_INIT): Likewise.
6380 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6382 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6385 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6389 * configure.ac (AC_INIT): Bump to 2.59d.
6391 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6395 * Makefile.maint (news-date-check): Do not require a leading `*'
6396 before the release date in NEWS.
6398 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6399 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6401 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6402 the instantiated file do not contain the string 'datarootdir'
6403 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6404 @mandir@, replace the reference '${datarootdir}' by the value.
6405 * tests/torture.at (datarootdir workaround): New test.
6406 * NEWS: Advertise this temporary fixup.
6407 Based on a patch by Bruno Haible, reported and analyzed by
6408 Paul Eggert and Noah Misch.
6410 2006-04-12 Eric Blake <ebb9@byu.net>
6412 * tests/autotest.at (Debugging a failed test): Fix comment.
6414 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6416 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6417 all the changes since 2006-04-07.
6419 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6421 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6422 succeeded, but `ln -s file dir' failed, take care to remove the
6423 leftover target before the next test, to prevent its spurious
6424 failure; also make sure `ln file dir' works before selecting it.
6425 Thanks to Keith Marshall for pointing this out.
6428 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6429 assignments in `at_debug_args', so that we put them correctly
6430 in the `run' script.
6431 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6432 Reported by Eric Blake.
6434 2006-04-11 Eric Blake <ebb9@byu.net>
6436 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6437 top-level tests after micro-suite has been run. Used in...
6438 (Debugging a successful test, Debugging script and environment),
6439 (Debugging a failed test): ...these new tests. The first of these
6441 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6442 macro, split out from...
6443 (AT_INIT): ...here, so that using -d also generates a run script.
6444 Document that -d inhibits top-level logging.
6445 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6446 inhibits top-level logging; debug scripts are created.
6448 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6450 * tests/autotest.at (Empty test, Empty check): New test to check it.
6452 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6455 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6457 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6458 the files if a problem appears. Make the empty *.at files
6459 read-only, too. Proposed by Ralf Wildenhues.
6461 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6463 * config/Makefile.am: Add comment to force updated Makefile.in.
6465 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6466 space only patch to this file, this patch causes the Makefile.in
6467 files that include freeze.mk to be updated, and thus have a
6468 newer time stamp again, which in turn makes a pristine CVS
6469 checkout have correct time stamps.
6471 * Makefile.maint (cvs-sv): New macro, to be used..
6472 (config.guess-url_prefix, config.sub-url_prefix)
6473 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6474 point to CVS text checkout of Gnulib files.
6475 (copyright-check): Bump current year.
6476 (announcement): Do not hard-wire `./announce-gen'.
6477 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6479 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6481 (wget_files): Update config.guess, config.sub, texinfo.tex by
6482 `wget-update', now that their URLs work again.
6484 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6486 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6487 Problem noted by Paul D. Smith.
6489 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6491 * doc/autoconf.texi: Remove unused words from word list.
6492 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6493 .x-sc_trailing_space: New files.
6495 * doc/standards.texi: Sync from gnulib.
6497 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6498 `LIBOBJDIR' as experimental.
6500 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6501 with a target directory; it's internally implemented as `cp'
6502 anyway, but since Autoconf advertises the possibility to use
6503 a target directory when LN_S is `ln -s', we need to find out.
6504 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6505 analyzed by Keith Marshall <keith.marshall@total.com>.
6509 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6511 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6512 confdefs.h as-is. In general, if it has backslash-newline or the
6513 like, then it doesn't work either to sort or to remove empty
6516 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6518 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6520 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6522 * lib/autom4te.in (Automake-preselections): Preselect
6525 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6527 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6528 apostrophe within a single-quoted string, as this is the usual
6529 tradition and is easier to read than '"'"'. Don't rely on the
6530 shell treating "$/" like '$/'. Use a more-consistent indenting
6533 2006-04-09 Eric Blake <ebb9@byu.net>
6535 * tests/autotest.at (Backquote command substitution),
6536 (Multiline backquote command substitution): Remove mistaken
6537 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6539 (Parenthetical command substitution, Multiline parenthetical
6540 command substitution): here.
6542 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6544 Import macros from gnulib (often changing their name).

6573 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6574 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6575 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6576 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6577 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6578 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6579 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6580 (Coding Style). Don't mention m4_expand_once.

6601 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6602 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6604 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6606 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6607 of the warning introduced by the 2001-08-28 change.
6609 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6610 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6612 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6613 variables shall be overriden by the cache.

6617 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6619 Revert the patch from 2006-04-01 and only improve
6620 _AS_DETECT_BETTER_SHELL:
6622 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6623 skip nonexistent directories.
6624 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6625 only shell candidates which exist.
6626 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6627 * lib/autotest/general.m4 (AT_INIT): No need to give three
6628 parameters to _AS_PATH_WALK.
6630 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6631 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6633 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6634 distinguish m4sugar macros.
6635 * tests/tools.at (autoupdating with aclocal and m4_include):
6636 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6637 test case by Noah Misch <noah@cs.caltech.edu>.
6639 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6641 Revert my change from 2006-03-17, in other words:
6642 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6644 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6645 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6648 2006-04-07 Eric Blake <ebb9@byu.net>
6650 * doc/autoconf.texi (Programming in M4sh): Document that
6651 AS_MKDIR_P exits the script on failure.
6652 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6654 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6656 * config/elisp-comp, config/install-sh, config/mdate-sh,
6657 config/missing, config/mkinstalldirs: Sync from Automake.

6672 Paul Eggert <eggert@cs.ucla.edu>,
6673 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6675 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6676 whether `set' quotes correctly: redirect stderr of the tested
6677 `set', and use a subshell, for Ultrix; use `sed' instead of
6678 `grep' for zsh `set' which may write binary output; match only
6679 at the beginning of a line, to avoid false positives.
6680 In order to avoid false positives by unrelated variables with
6681 multiline content, put the dump algorithm in a subshell and
6682 unset all variables containing newlines (except some which are
6683 special to the shell). Warn about cache variables that are
6686 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6688 * config/config.guess, config/config.sub, config/texinfo.tex:
6691 * tests/mktests.sh: Reword comments.
6693 * tests/mktests.sh: Only skip internal macros starting with
6694 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6695 Update exclusion lists for the test suite to this end:
6696 (AC_ARG_VAR): Do test this now.
6697 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6698 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6699 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6700 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6702 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6703 shell issue with double-quoted command substitutions of native
6705 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6708 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

6721 <tab><space> where this makes sense.
6723 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6725 * tests/Makefile.am (maintainer-check-posix):
6726 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6728 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6729 ac_config_<foo>s again, sometimes normalized, sometimes not.
6730 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6731 (AC_CONFIG_COMMANDS): Do not do so here.
6732 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6733 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6734 2005-07-25 rewrite. Noticed by Noah Misch.

7680 comparing its address. Intel's interprocedural optimization was
7681 outsmarting the old heuristic. Problem reported by
7684 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7686 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7688 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7690 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7691 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7693 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7695 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7696 before removing it (chmod -R u+rwx); there are three instances of this.
7698 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7699 Stepan Kasal <kasal@ucw.cz>
7701 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7702 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7703 make its content writable before removing it. Remove an errorneous
7704 comment from the end, where the logs of the failed tests are copied
7705 to the main log file.
7707 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7709 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7710 in case the computer is too quick. Double quote the configure.ac
7713 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7714 problems if the testsuite were running too fast.
7716 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7718 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7719 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7720 (which belong to Xt, not X itself). See Debian bug 327655.
7721 * NEWS: Mention this.
7723 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7725 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7727 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7729 * config/move-if-change: Don't output "$2 is unchanged";
7730 suggested by Ben Elliston. Handle weird characters correctly.
7732 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7734 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7735 calls, so that the final expansion of this macro is shorter.
7736 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7737 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7738 the cleanup there. Use AS_VAR_* macros, to be more general.
7739 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7741 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7743 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7745 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7747 * doc/autoconf.texi (Configuration Headers): Add an index entry
7750 2005-08-26 Pavel Roskin <proski@gnu.org>
7752 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7753 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7756 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7758 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7759 The previous patch didn't work, so try a better one.
7761 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7763 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7764 in the example. Reported by Bruno Haible.
7765 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7766 "if $undefined_var;" succeeds with my shell.
7768 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7769 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7770 but change the m4_divert_text to m4_divert_once.
7772 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7774 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7775 Work around bug in Solaris /usr/xpg4/bin/awk.
7776 The bug is present in at least Solaris 8 through 10.
7778 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7780 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7781 some evil values and relying on the fact that $* concatenates the
7782 parameters by the first character from IFS.
7784 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7785 Stepan Kasal <kasal@ucw.cz>
7787 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7788 first header appears, define AH_HEADER.
7789 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7790 Update limitations about when to call AC_CONFIG_HEADERS.
7791 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7792 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7793 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7794 ``Configuration Actions''; fix their index entries.
7796 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7797 options correctly. Process N-M as M-N if M is smaller than N.
7798 Process ranges correctly so that N-N will run only N.
7799 Sort and uniquify the tests that will be run. If there is more
7800 than one test, reinsert the banners for the tests.
7801 * tests/autotest.at (Keywords): Unmark XFAIL.
7803 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7805 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7806 before passing the macro name to AH_TEMPLATE.
7808 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7809 now opens log after option processing; in particular, --version
7810 and --help do not touch config.log.
7812 * Makefile.maint: Revert the change from 2005-08-12.
7814 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7816 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7818 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7820 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7822 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7823 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7826 * doc/autoconf.texi (Defining Symbols, Changed Results):
7827 Prepend to LIBS, not append, in examples.
7829 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7831 When building in place, set srcdir="."; suggested by Tim Van Holder.
7833 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7834 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7835 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7836 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7837 does not mean "no --srcdir option".
7839 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7841 * tests/autoscan.at (autoscan): New file.
7842 * tests/suite.at: Use it.
7843 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7844 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7846 * tests/autotest.at (Keywords): Test keywords combinations.
7848 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7850 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7851 add "2>&1"; gzip 1.2.4 prints help on stderr.
7853 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7855 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7856 was pushdef'ed twice while popped only once. Push it only once.
7857 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7859 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7861 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7862 prefixed by mere "===", not "configure: === ".
7864 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7866 * Makefile.maint: Update from Bison.
7868 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7869 "<tab>" in comment, so that the point is understandable.
7871 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7873 Rewrite substantial part of lib/autoconf/status.m4.
7874 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7875 and CONFIG_COMMANDS are not processed in four separate loops.
7876 Instead, there is one main loop. This alows that the common code
7877 is expanded only once, thus config.status (and configure) is smaller.
7879 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7880 the AC_LIST_FILES and cousins macros are no longer used.
7882 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7883 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7884 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7885 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7886 contain the initialization, nor the for loop, nor the associated
7887 commands; all these go to ...
7888 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7889 _AC_OUTPUT_CONFIG_STATUS.
7890 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7891 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7892 (_AC_OUTPUT_FILE): The creation of the sed script ...
7893 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7894 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7895 _AC_OUTPUT_MAIN_LOOP.
7896 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7897 _AC_CONFIG_COMMANDS): Use ...
7898 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7899 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7900 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7901 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7902 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7903 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7905 (_AC_CONFIG_UNIQUE): Update.
7906 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7907 Replaced by this ...
7908 (_AC_LIST_TAGS): ... new common macro.
7909 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7910 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7911 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7912 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7913 this didn't belong to the `config commands' section.
7914 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7915 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7916 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7917 to the `config commands' section either.
7918 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7919 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7921 ... and many changes to the comments nearby.
7923 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7924 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7925 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7926 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7927 (#define header templates): The comment at the top of the generated
7928 header now includes the name(s) of the source file(s).
7930 Several unrelated small changes:
7932 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7933 parameter to AC_DIAGNOSE.
7934 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7935 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7936 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7937 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7939 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7940 in AC_OUTPUT doesn't double-quote it either.
7941 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7944 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7946 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7947 versions of Portland Group compiler produce single- and double-quoted
7948 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7949 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7951 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7953 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7954 This is a corrected version of yesterday's patch.
7956 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7958 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7959 path, too; insert a "===" to emphasize the line.
7961 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7962 ac_cv_build_alias to ac_build_alias.
7963 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7965 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7966 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7967 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7968 (AC_ARG_VAR): ... here.
7969 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7972 Keep a list of all precious variables and process them with one simple
7973 for loop, instead of expanding all commands, or, OTOH, complicated
7974 processing of output of "set".
7975 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7976 variable names in new macro...
7977 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7978 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7979 a loop to assign all ac_env_* and ac_cv_env_* variables.
7980 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7982 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7983 its value to shell variable ac_precious_vars and call
7984 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7985 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7986 _AC_ARG_VAR_VALIDATE.
7988 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7989 and the AC_SUBSTs ...

7993 the ac_subst_files section in config.log.

8006 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8007 They are generated by the Tru64 v5.1B shell.

8011 Fix my changes from 2005-07-01; reported by Noah Misch.
8012 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8013 description, the macro now accepts only a single tag.

8016 Fix cases when the varsions of Autoconf and Autotest don't match.
8017 Reported by Noah Misch.
8018 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
8019 at_top_builddir, for compatibility with older autotest.
8020 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
8021 is not set, use at_top_builddir, for compatibility with older
8022 versions of autoconf.
8024 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8026 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
8027 Problem reported by Patrick Welche.
8029 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8031 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8032 sed substitution command, so that we allow | in program prefixes
8033 and program suffixes. (& is a problem anyway; we're not fixing
8035 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8036 configure_input, top_builddir, srcdir, etc.
8037 * lib/autotest/general.m4 (AT_INIT): Likewise, for
8038 PATH_SEPARATOR in AUTOTEST_PATH.
8040 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
8042 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
8043 for loop over config.site files using `set', to allow
8044 directory names containing IFS characters.
8046 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
8048 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
8049 directories with weird names. Apparently some people like living
8050 on the edge. However, improve the test that "pwd" actually does
8051 report a name for the working directory.
8052 * NEWS: Remove the claim that we test for funny chars in dir names.
8054 2005-07-01 Stepan Kasal <kasal@ucw.cz>

8070 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
8071 document to output the default config_* lists to config.status.
8072 Don't recognize option --file, if the functionality is not there.
8073 Likewise for --header; moreover, recognize --he and --h as shortcuts
8074 for --help in that case.
8076 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8077 matches the order of execution. No code changed.

8098 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
8099 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8100 (AC_SUBST): Call it.
8101 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8102 the directory specific variables; but don't call it for configure_input.
8104 2005-06-28 Derek Price <derek@ximbiot.com>
8106 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8109 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8111 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
8112 directory have inherent problems with special characters like spaces,
8113 due to limitations in Make syntax. Problem reported by Alexandre
8115 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
8116 Also, fix Tru64 porting problem with shell patterns,
8117 reported by Ralf Wildenhues.

8127 Fix some more shell quoting problems. Prompted by a bug report
8128 from Justace Clutter.
8129 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8130 variable into diagnostic. Make the diagnostic an error, not a warning,
8131 because we really don't support spaces and suchlike in dir names.
8132 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8133 Don't worry about backslashes in srcdir; it can't happen now.
8134 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8135 Simplify ac_optarg handling.
8136 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8162 (Special Shell Variables): Fix sed code this in the example.
8163 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8164 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8166 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

8172 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8174 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8176 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8177 * doc/autoconf.texi:
8178 Don't mention Solaris versions so much, if a
8179 problem is common to all extant versions of Solaris. Say "SunOS
8180 4" instead of "SunOS" for SunOS 4.
8181 (awk): Mention more of the limitations of traditional Awk.

8192 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8193 on Mac OS X 10.4 reported by Peter O'Gorman in:

8224 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8225 -u, since it outputs chatter if the input files are the same.
8226 Problem reported by Ralf Menzel.
8228 2005-06-08 Derek Price <derek@ximbiot.com>
8230 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8231 renaming them since they are about to be redefined anyhow.
8233 2005-06-08 Derek Price <derek@ximbiot.com>
8235 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8236 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8237 Move m4_undefine to alphabetical order.
8239 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8241 * README: Recommend GNU M4 1.4.3 or later.
8242 * doc/autoconf.texi (Introduction): Likewise.
8243 Reword to avoid some formatting glitches.
8244 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8245 Clarify explanation of HP compiler bug.
8246 Redo example output tp match current CVS snapshot.
8247 Use @example.org in email addresses when the examples
8248 might get inadvertently cut-and-pasted into user code.
8249 Remove example of autom4te usage that doesn't seem to work now.
8250 Use modern AC_INIT (except when the example is meant to be
8251 shown with Autoconf 2.13).
8252 Update ksh info for Solaris 9 and later.
8254 Modernize description of Automake versions a bit.
8255 Don't claim a future version of Autoconf is near.

8261 follows its own advice about quoting better.
8262 Reword to avoid some formatting glitches.
8263 * doc/installt.exi: Reword to avoid some formatting glitches.
8265 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8266 Tru64 ksh pattern matching bug. Reported against Libtool by
8267 Albert Chin <libtool@mlists.thewrittenword.com> and
8268 Nicolas Joly <njoly@pasteur.fr>.
8270 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8272 m4_cdr of one-member list was [[]] (one-member list containing an
8273 empty string) instead of [] (an empty list. Callers were skewed to
8274 match this misbehaviour. As a consequence of this:
8275 - m4_foreach([x], [], [foo]) expanded to `foo', while
8276 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8277 This bug has been fixed:
8279 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8280 expand to an empty string; print error msg if called without
8282 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8283 misbehaviour; handle [] and [[]] correctly.
8285 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8287 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

8289 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8291 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8293 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8294 swallow records with more than 99 fields.
8295 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8296 parse the long line.
8298 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8300 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8301 swallow literals longer than 399. Reported by Ralf Wildenhues.
8302 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8303 to workaround this limitation.
8305 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8307 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8308 to gfortran, and make these the first two compiler names
8309 checked (following the general autoconf preference for gcc).

8313 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8314 (DISTCLEANFILES): Remove $(check_SCRIPTS).

8319 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8320 expression of unbounded size when processing the --list
8321 option. This runs afoul of a limit of 399 bytes per regular
8322 expression on AIX. Problem reported by Ralf Wildenhues.
8324 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

8327 * doc/autoconf.texi (Particular Headers): Reword example
8328 for multiline stdbool replacement.

8330 give all the details about |#_!!_#|.
8331 Reword description of line replacement.
8333 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8335 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8336 now contain newlines, and substituted files must be referenced on
8337 a line alone; the sed scripts to substitute them are now very
8339 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8340 commands can be put in a sed script portably.
8341 * doc/autoconf.texi (Setting Output Variables): Document above
8342 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8343 use of multiline substitution.

8354 classes in shell scripts. The test was too brittle.
8356 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8358 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8359 * doc/autoconf.texi (Limitations of Builtins): Document this
8362 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8364 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8365 common code; used in many places in the tree.
8366 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
8367 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8369 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

8372 messages when ac_unique_file is not found.
8373 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8374 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8375 commands, for consistency with AC_MSG_ERROR and such.
8377 * bin/autoconf.as: Make more use of "shift 2" in option processing.

8390 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8391 (ac_top_builddir): ... this ...
8392 (ac_top_build_prefix): ... to this; the old name is also kept, for
8393 backward compatibility.
8394 (ac_top_builddir_sub): New variable, without the trailing slash,
8396 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

8410 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8411 argument to m4_foreach. I guess it was necessary in the past,
8412 but I think it's a no-op now.

8416 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8417 ``cat <<_ACEOF'' commands to one.

8550 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8551 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8552 comment and reduce m4_default([foo], []) to [foo].
8553 (m4_strip): Update the explanation.
8555 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8557 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8558 Remove core.conftest.* too; it's generated by Tru64 5.1.
8559 Problem reported by Jennis Pruett.
8560 * lib/autoconf/functions.m4
8561 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8562 Don't bother to remove core files; AC_RUN_IFELSE should do that

8607 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8609 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8610 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8611 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8612 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8613 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

8617 * NEWS: The configure command now warns you if you attempt to use
8618 a directory whose name contains a special character like space,

8633 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8634 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8635 ac_pwd, and quote srcdir.
8636 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8638 * doc/autoconf.texi: Fix some systematic formatting problems.
8639 ".)" needs a following @: if not at the end of a sentence, and
8640 similarly for "!)". "etc." should be preceded by a comma.
8641 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8643 2005-03-22 Bruno Haible <bruno@clisp.org>
8645 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

8657 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8658 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8659 from a Common Lisp's `cl'.
8660 (AC_PROG_CXX): Behave according to the documentation: don't
8661 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8662 make the variable CCC precious; use `cl.exe', not `cl'.

8665 Alexandre Duret-Lutz <adl@gnu.org>
8667 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8668 /dev/null, as "configure" shouldn't read stdin, and this insulates
8669 us from problems (e.g., when testing for "cl"). Also, do this
8670 redirection before invoking "hostname" or "uname", and keep the
8671 original input stream available via...
8672 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8673 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

8685 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8686 newline if neither \c nor -n work, as that would output two
8687 newlines. Prefer -n to \c. Reported by Stepan Kasal.

8691 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

8695 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8697 Undo previous change, except keep the change to
8698 lib/autoconf/programs.m4 that replaced grep with shell
8699 pattern-matching. This is because net-snmp configure reads stdin.
8700 Reported by Noah Misch.

8704 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8705 from /dev/null, as "configure" shouldn't read stdin, and this
8706 insulates us from problems (e.g., when testing for "cl").
8707 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8708 before invoking "hostname" or "uname".
8709 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8710 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.

8712 "</dev/null" since it's now done at the top of 'configure'.
8713 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8714 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8715 Also, replace grep with shell pattern-matching, to save a process.

8719 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,

8738 Fix some @code's that should have been @env's, and vice versa.
8739 Sort environment variable names.
8740 Mention that shells no longer inherit IFS.
8741 Don't recommend PATH_SEPARATOR=';' so strongly.
8742 Mention that $RANDOM might expand to the empty string.
8743 "symlink" and "soft link" -> "symbolic link".

8820 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

8883 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8884 Update the long comment explaining it.
8886 m4_require no longer writes an ``is required by'' line to the
8887 execution stack. It contains only one bit of non-redundant
8888 information: that the macro was required, not called. And even
8889 this bit is useless in most situations: have you ever met a macro
8890 which both calls and requires the same macro?
8892 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8893 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8898 execution stack; slightly improve the out-of-a-defun error message.
8899 (_m4_divert_grow): New macro, counter for the temporary diversions.
8900 (_m4_require_call): Use it.
8901 * tests/m4sugar.at (m4_require): Expect output without the
8902 ``is required by'' messages.

8940 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8941 Warn about newline stripping in `` and $(). Update Solaris
8943 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8944 X insulates us from future changes to Posix.
8945 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

8993 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
8994 (_m4_divert_n_stack): New macro; the expansion is
8995 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
8997 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
8998 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8999 stored in _m4_divert_diversion or _m4_divert_dump.
9000 (m4_divert_pop): When the parameter is given, compare the symbolic
9001 name with the last diversion pushed on the stack. Previously, the
9002 current diversion was compared with the numeric value of the
9003 diversion given as the parameter.
9004 (m4_require): If the macro hasn't been expanded yet, call ...
9005 (_m4_require_call): this new macro.

9038 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
9039 signals that the package uses Automake; a `Makefile.am' is typical but
9040 not essential. Reported by Magnus Therning.

9523 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9525 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9527 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9528 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9529 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9531 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9533 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9534 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9535 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9536 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9537 * lib/autom4te.in (Automake-preselections): Preselect
9538 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9540 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9542 * lib/autom4te.in (Automake-preselections): Preselect
9543 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9546 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9548 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9550 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9551 Document problem with "`""`" in pdksh POSIX mode.
9553 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9555 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9556 with pdksh, too. Problem reported by Patrick Welche via
9558 * doc/autoconf.texi (Shellology): Note that set -o posix is
9559 useful for pkdsh, too.
9561 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9563 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9564 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9565 Don't fail if ENV or BASH_ENV is readonly.
9566 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9567 etc. are read only. Problem reported by Ludovic Courtes.
9569 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9571 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9572 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9575 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9577 * doc/autoconf.texi (File System Conventions): Warn about
9578 names like "aux". Problem reported by Eric Blake.
9580 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9581 by zero instead of array size, so that we can use any arithmetic
9582 constant expression (instead of requiring an integer constant
9583 expression). This allows us to test expressions like DBL_MAX <
9584 LDBL_MAX, which didn't conform to the C standard using the old
9586 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9587 now that we can do floating-point tests at compile time.
9589 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9591 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9592 and LDBL_EPSILON, as the resulting expression isn't an
9593 integer constant expression and violates the C standard.
9594 Problem reported by Nelson H. F. Beebe. Also, check
9595 for "L" suffix, and check that long double doesn't have
9596 worse range or precision than double, that mixed-mode
9597 arithmetic doesn't generate a diagnostic, that double
9598 constants fit in long double.
9600 2004-06-03 Kevin Ryde <user42@zip.com.au>
9602 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9603 malloc(0) and realloc(NULL,size).
9605 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9608 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9610 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9611 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9614 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9616 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9617 can be rewritten using if-then-else. Suggested by Bruno Haible.
9619 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9621 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9622 Problem reported by Stepan Kasal.
9624 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9626 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9627 change). Patch reported by Ralf Wildenhues in
9628 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9630 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9631 function F exists if the compiler and linker let you compile an
9632 expression like (F != 0). Recent versions of GCC optimize away
9633 the reference to F in that case, since every function address must
9634 be nonzero, so the link succeeds even if F does not exist.
9635 Problem reported by Manu in
9636 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9638 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9639 "Unix". Many uses changed.
9640 (Limitations of Builtins): Explain better why the ! command isn't
9643 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9645 * lib/autom4te.in (Automake-preselections): Preselect
9646 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9648 2004-05-19 Kevin Ryde <user42@zip.com.au>
9650 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9651 referencing AC_FUNC_STRERROR_R.
9653 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9654 note pessimistic assumption when cross compiling.
9656 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9658 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9659 (until 2004) invoked subcommands with sh -e, contra POSIX.
9660 Reported by Kevin Ryde.
9662 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9664 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9665 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9666 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9667 `test -f " /usr/bin/grep"', which _always_ failed.
9668 (AC_PROG_SED): Ditto bogus PATH fix.
9669 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9670 requires that grep correctly supports _multiple_ `-e' options, rather
9671 than stating only that grep should accept `-e'.
9673 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9675 Port to C99, which requires that 'exit' be declared.
9677 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9678 to ensure that stdlib.h is included.
9679 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9680 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9681 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9682 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9683 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9684 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9685 when using 'exit' in a test; C99 requires that 'exit' be declared.
9687 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9689 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9690 now prefers 'grep' implementations that accept -e.
9691 (Limitations of Usual Tools): Describe problems of traditional
9692 egrep and fgrep with long input lines, and of traditional grep
9694 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9695 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9696 All callers changed. Append /usr/xpg4/bin to the PATH, for
9698 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9699 the user with complaints about multiple -e options.
9700 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9701 Define it with AC_PROG_GREP.
9702 * configure.ac (AC_PROG_GREP): Add.
9703 * lib/freeze.mk (GREP): New macro.
9705 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9707 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9708 a possible candidate only after all others fail, rather than
9709 consulting it first. This improves backward compatibility by
9710 better reflecting the way shell selection occurred in previous
9711 versions of Autoconf, and should help to avoid triggering latent
9712 problems in other packages, such as the one in Automake where zsh
9713 is not handled robustly:
9714 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9715 Although it is not Autoconf's responsibility to work around
9716 problems in Automake, it nevertheless makes sense to avoid
9717 introducing unnecessary incompatibilites.
9719 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9720 Gary V. Vaughan <gary@gnu.org>
9722 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9723 how deeply nested we are when a suitable tool is found, set the
9724 ac_path_TOOL_found flag.
9725 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9726 nested we are in this macro. Break out of all 3 nested loops if
9727 ac_path_TOOL_found is set.
9729 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9731 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9732 of the _AS_PATH_WALK loop too if GNU flavor is found.
9734 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9736 * doc/autoconf.texi (Limitations of Make): Update documentation
9737 for `$<'. New entry `Long lines', based on a report from Simon
9738 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9739 paragraph about DJGPP, based on a mail from Richard Dawe.
9741 2004-04-20 Paul Eggert <eggert@twinsun.com>
9743 * tests/c.at (C keywords): Don't assume that GCC supports
9744 "restrict" and "inline", as sufficiently-old GCC versions do not
9745 (also, GCC configured to be in pedantic C89 mode does not).
9746 Problem reported by Sumit Pandya in:
9747 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9749 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9750 consider -g to work if it generates warnings when plain compiles
9751 don't. Problem reported by Braden McDaniel in:
9752 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9754 * doc/autoconf.texi (Slashes): New section, to document a problem
9755 reported by Jim Meyering in:
9756 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9758 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9759 linker output files before linking, to work around IRIX 6 linker bug.
9760 Problem reported by Rainer Orth in:
9761 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9763 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9765 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9766 best tool so far counter rely on the tool path variable name to
9767 avoid checks for one tool being affected by the results of running
9768 the length check on a previous tool.
9770 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9771 match expression argument, as different greps have different
9772 regular expression flavours.
9773 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9775 (AC_PROG_EGREP): Pass 'EGREP$'.
9776 (AC_PROG_GREP): Pass 'GREP$'.
9778 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9780 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9781 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9783 2004-03-29 Paul Eggert <eggert@twinsun.com>
9785 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9786 Types, Specific Compiler Characteristics, System Services,
9787 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9788 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9789 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9790 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9792 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

9803 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9804 now defines HAVE_DECL_TZNAME if it is declared, when
9805 HAVE_STRUCT_TM_TM_ZONE is not defined.
9806 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9807 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

9818 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9819 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9820 H. F. Beebe for the bug report.
9822 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9824 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9825 quoted -cmdline argument in Portland Group compiler (bug
9826 reported by Jeffrey J. Barteet).

9870 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9871 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9874 2004-03-03 Paul Eggert <eggert@twinsun.com>
9876 * bin/Makefile.am (edit): Don't use $< in a context where
9877 POSIX doesn't require support for it. Use $@.in instead.
9878 Problem reported by Anthony N. Frasso in
9879 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

9908 AC_SUBST provides no portable way to escape literal newlines.
9910 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9911 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9912 Darwin uses -lcrt2.o and there's little point to cataloging all
9913 the system variants. Partial fix reported by Andreas Waechter in:

9989 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9990 2003 (except 1997) to the list of copyright years. This undoes
9991 the 2003-05-22 change, which removed the older years from the list.
9992 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

9998 grep or ggrep program in PATH that accepts as long lines as
10000 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

10003 egrep and fgrep respectively if $GREP -E/-F don't work.
10004 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10005 _AC_PROG_GREP, and AC_PROG_SED.
10006 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10007 longest input length accepted by a command.
10008 (AC_PROG_SED): Use it.
10009 * doc/autoconf.texi (Particular Programs): Document the changes.
10012 2004-01-27 Paul Eggert <eggert@twinsun.com>
10014 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
10015 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10016 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
10017 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
10019 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
10020 bin/autoconf.in, config/Makefile.in, config/config.guess,

10036 2004-01-26 Paul Eggert <eggert@twinsun.com>
10038 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10039 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10040 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10041 not <inttypes.h>. Problem reported by Tim Mooney in
10042 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10043 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10046 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10047 otherwise "make check" fails because it forbids cmp (I guess
10048 because cmp treats files as binary on DOS-like systems).
10050 * tests/mktests.sh: Update copyright date to 2004, since some tests
10051 have changed in 2004.
10053 2004-01-23 Gary V. Vaughan <gary@gnu.org>

10056 non-truncating sed or gsed program in PATH.
10057 * tests/acprograms.at: Add it.

10061 2004-01-15 Paul Eggert <eggert@twinsun.com>
10063 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10064 -std1 disables some useful extensions on Tru64. Problem reported
10065 by N. Lichtmaier in
10066 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10068 2004-01-14 Paul Eggert <eggert@twinsun.com>
10070 * doc/autoconf.texi (Programming in M4sh): Document that
10071 AS_MKDIR_P succeeds if the destination is a symbolic link
10072 to an existing directory.
10073 (Limitations of Usual Tools): Note that mkdir -p might not
10074 succeed on symlinks to directories.
10076 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10078 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10079 * bin/autoheader.in: Grammar fix in message.
10080 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10081 Test for dir before calling mkdir -p. (trivial changes)
10083 2004-01-13 Eric Blake <ebb9@byu.net>
10085 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10086 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10088 2004-01-10 Jim Meyering <jim@meyering.net>
10090 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10092 2004-01-09 Paul Eggert <eggert@twinsun.com>
10094 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10095 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10096 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10097 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10098 AC_COMPILE_IFELSE, since we now assume our caller invokes
10099 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10100 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10101 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10102 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10104 2004-01-07 Paul Eggert <eggert@twinsun.com>
10106 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10107 `"'...'"`, as it's confusing (and I suspect it may not work on
10108 some platforms). The code was incorrect anyway, as it assumed
10109 that \$ evaluated to itself in that context. Reported by
10110 Alexandre Duret-Lutz.
10112 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10114 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10115 and _LT_AC_TAGCONFIG.

10142 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10143 Use "rm -f" to remove conftest.sed, not plain "rm".
10144 Bug reported by David Relson in
10145 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10147 * Makefile.am (autom4te-update):
10148 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10149 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10150 * doc/autoconf.texi (Guidelines): Likewise.

10164 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10165 -c -o might not work. From a suggestion by Kevin Ryde.
10166 (C Compiler, Generating Sources, Limitations
10167 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10168 Don't put '-o' after non-options, as POSIX doesn't allow this.
10169 Mention that cc's name might be gcc or c89 or whatever.
10171 2004-01-04 Kevin Ryde <user42@zip.com.au>
10173 * doc/autoconf.texi: Add various further index entries.

10180 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10182 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10183 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10184 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10185 explanation clearer.
10187 2003-12-24 Andreas Schwab <schwab@suse.de>
10189 * doc/autoconf.texi (Default Includes): Fix misspelling of

10195 * configure: Regenerate.
10196 * tests/atlocal.in: Store the result here.

10199 of explicitly testing.
10200 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10201 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10202 * tests/tools.at (Syntax of the shell scripts): Simplify

10279 2003-11-17 Paul Eggert <eggert@twinsun.com>
10281 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
10282 into the initial confdefs.h, to work around a bug in NextStep 3.3

10287 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10288 than $target since the latter is not usual, add guidelines on when to
10289 use or not use the system type.

10438 (Shell Substitutions): Warn about $((...)).
10439 (Parentheses): New section.
10441 2003-10-15 Kevin Ryde <user42@zip.com.au>
10443 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
10444 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
10446 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
10448 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
10451 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
10453 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
10454 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10456 2003-10-10 Andreas Schwab <schwab@suse.de>
10458 * bin/autoheader.in: Avoid empty first line in --version and
10460 * bin/ifnames.in: Likewise.
10462 2003-10-09 Paul Eggert <eggert@twinsun.com>
10464 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
10465 Issue a more-informative diagnostic.
10466 Problems reported by Eric Sunshine.
10468 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
10470 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10471 -mGLOB_options_string stuff for Intel ifc, which can cause
10472 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10473 pattern-matching instead of grep.
10475 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
10477 * doc/autoconf.texi: Document new FC Fortran macros.
10479 2003-10-08 Gary V. Vaughan <gary@gnu.org>
10481 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
10482 that future autopoint/aclocal/automake/autoreconf will be able
10483 to trace to find where to install local m4 macros.
10484 * doc/autoconf.texi (Input): Document it.
10487 2003-10-06 Gary V. Vaughan <gary@gnu.org>
10489 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
10490 -lcrtbegin.o to list of ignored flags and fix underquoting of
10493 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10495 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10496 cache variable instead of $G77 to decide whether to include -O2,
10497 since $G77 is specific to Fortran 77.
10499 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10501 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10502 free" flag. Re-order flags tested into rough order of popularity.
10504 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10506 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10507 arguments so that it can be used with syntax identical to
10508 AC_PROG_F77, and so that we can more easily decide to
10509 remove/deprecate the DIALECT optional argument in the future if it
10510 proves troublesome.
10511 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10512 non-freeform-supporting compilers. Document freeform flags.
10514 2003-10-03 Akim Demaille <akim@epita.fr>
10516 * configure.ac: Look for emacs, not macs.
10517 Reported by Eric Sunshine.
10519 2003-10-03 Akim Demaille <akim@epita.fr>
10521 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10522 * bin/autoreconf.in (autoreconf_current_directory): Create the
10523 AUX_DIR if needed, for sake of automake --add-missing etc.
10524 Suggested by Alexandre Duret-Lutz.
10526 2003-10-03 Akim Demaille <akim@epita.fr>
10528 * configure.ac: Quotation and formatting changes.
10529 (EMACS): Don't set it if it is not recent enough to support

10562 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10563 have been created when invoking the compiler.

10575 Problem reported by Lars J. Aas in
10576 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10577 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10578 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10579 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10581 2003-09-26 Akim Demaille <akim@epita.fr>
10583 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10584 directory for AC_CONFIG_COMMANDS' first argument exists.
10585 This makes valid the invocation of _AC_SRCPATH that follows.
10586 Reported by Eric Sunshine.
10587 * doc/autoconf.texi (Configuration Commands): Adjust.
10589 2003-09-26 Akim Demaille <akim@epita.fr>
10591 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10592 Reported by Ralf Corsepius.
10594 2003-09-26 Akim Demaille <akim@epita.fr>
10596 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10598 Actually, use AU_ALIAS.
10601 2003-09-26 Paul Eggert <eggert@twinsun.com>
10603 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
10604 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
10605 Problem reported by Eric Sunshine in:

10610 The test suite are sometimes assigning timings incorrectly.
10611 Reported by Henk Krus.
10612 Diagnosed by Nicolas Joly.
10614 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10616 Instead of making AT_help a sequence of assignments to grow
10617 $at_help_all, just make AT_help_all be the growing contents of
10618 $at_help_all, and make a single assignment in...
10620 (at_times_skip): Flip the meaning and rename as...
10621 (at_times_p): this.
10622 (AT_INIT): When summarizing the test that ran, remove
10623 $at_times_file after use, and check it is present before trying to
10626 2003-09-25 Akim Demaille <akim@epita.fr>
10630 * bin/Makefile.am (edit): Handle '@configure_input@'.
10631 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10632 (ifnames): chmod -w.
10633 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10634 executables, not bin/ executables! Otherwise all the magic needed
10635 to find non installed files is turned off. This caused a failure
10636 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10637 as found in its environment (sent by tests/autoreconf): pointing
10638 to bin/autom4te that could not find its files.
10639 * tests/mktests.sh: Force the replacement of generated files, for
10640 the sake of "mv" program that are interactive when overwriting a
10642 * config/install-sh: Upgrade from CVS Automake.
10644 2003-09-23 Paul Eggert <eggert@twinsun.com>
10646 * doc/autoconf.texi (Limitations of Builtins): Document test -h
10647 versus test -L issues.
10649 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10650 Paul Eggert <eggert@twinsun.com>
10652 Trivial change to support GCC's configuration procedure.
10653 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10654 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10655 about inconsistency if the preprocessor is set to give errors for

10688 willing to edit the output files.
10690 2003-09-10 Akim Demaille <akim@epita.fr>
10692 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10693 and AC_FC_FREEFORM.
10694 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10695 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

10731 2003-09-04 Akim Demaille <akim@epita.fr>
10733 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10735 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10737 Add support for newer Fortran dialects. The F77 interface is
10738 unchanged, and continues to support Fortran 77. New FC macros
10739 correspond to all the old F77 macros, with output variables FC,
10740 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10741 available dialect, but older dialects can be specified. There are
10742 new macros AC_FC_SRCEXT to set the source extension, and
10743 AC_FC_FREEFORM to accept free-form source files.
10745 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10747 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

10764 Rewrite in terms of the above.
10765 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10766 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

10778 * tests/m4sugar.at (cross_warning): Make sure to enable the

10780 * tests/local.at: Require 2.57.
10781 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10782 are defaulted by AT_CHECK anyway.
10783 Use AT_CHECK_AUTOM4TE.
10784 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10787 2003-08-27 Akim Demaille <akim@epita.fr>

10843 * bin/autom4te.in: Adjust to output the call stack.

10859 Use &verb, not &verbose.
10861 2003-08-21 Akim Demaille <akim@epita.fr>
10863 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10865 ($help): Use Autom4te::ChannelDefs::usage.
10866 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10867 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10869 2003-08-21 Akim Demaille <akim@epita.fr>
10871 First stab at preserving warnings between calls to autom4te,
10872 including when the cache is used.
10874 There are still several issues: (i) there are too many runs of m4
10875 (one for include, one for warnings, and some more), (ii) warnings
10876 spreading on several lines are not handled gracefully, (iii) the
10877 code meant to have the call stack display for errors does not work
10878 (its handling should move from m4 to autom4te).
10880 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10882 (@preselect): Add m4_warn.
10883 ($exit_status): Remove, use $exit_code.
10884 ($help): Use Autom4te::ChannelDefs::usage.
10885 (&handle_m4): No longer define the m4_warnings.
10886 At each run, extract and report the warnings.
10887 Always cache the result, including if the exit status is on
10888 failure, since if nothing changes, we should result in the same
10889 failure, hence we can use the cache.
10890 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10891 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10893 (m4_warn): Redefine as a do-nothing: it is its invocation that
10894 matters, as warnings are now reported via traces.
10895 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10896 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10897 the latter reveals calls to the former.
10901 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

10939 (&xsystem, &contents): Remove, since they are exported by...

11029 -lcrt1.o, for OS X. (trivial change)

11033 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
11034 inside '#ifndef __cplusplus'. Problem reported by

11040 'long', not 'int', for benefit of Sun's recent C++ compilers
11041 (trivial change). See:
11042 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

11058 From Gareth McCaughan.
11060 2003-06-23 Akim Demaille <akim@epita.fr>
11062 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11063 not all of them. This fixes 1. the fact that when testing
11064 Autoconf there are many many config.log, 2. the incorrect use of
11065 top_srcdir to find config.log.
11066 Don't mix the detailed output of failed test with the summary of
11067 failures. Rather, append detailed log afterwards.
11069 2003-06-23 Akim Demaille <akim@epita.fr>
11071 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11072 always run: output config.log on $at_group_log.

11076 * tests/torture.at (#define header templates): Don't use quotes in

11129 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11130 (AT_INIT): Support for expected failures.
11132 2003-06-02 Akim Demaille <akim@epita.fr>

11141 2003-05-28 Paul Eggert <eggert@twinsun.com>
11143 * NEWS, doc/autoconf.texi (Particular Functions),

11145 is the inverse of localtime.

11149 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11150 (handle_exec_errors): New function. Work around $! being
11151 altered by WEXITSTATUS.
11152 (xqx, xsystem): Use handle_exec_errors.
11154 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11156 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11157 Do not call `_exit()', simply modify `$?'.
11158 (xsystem): Reset $! before running system, and check it afterward.
11159 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11160 63 for version mismatches.
11162 2003-05-23 Akim Demaille <akim@epita.fr>
11164 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11165 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11166 the middle of a line).
11167 * lib/m4sugar/m4sugar.m4: Likewise.
11168 Remove useless spaces in comments.
11170 2003-05-23 Akim Demaille <akim@epita.fr>
11172 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11173 exit 63, so that we (or Automake's "missing") can tell the
11174 difference with a plain failure.
11175 * doc/autoconf.texi (Notices): Adjust.
11177 2003-05-23 Akim Demaille <akim@epita.fr>

11184 Paul Eggert <eggert@twinsun.com>
11186 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11187 Remove `#include <stdlib.h>' from the list; we should never
11188 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11189 resulting namespace pollution would cause other tests to fail.
11190 Configure scripts run with some older versions of g++ and HP's
11191 aCC would fail due to such an #include. Problems reported by
11192 Matthew Mueller in <http://bugs.debian.org/120704> and by
11194 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11195 In the test, use the test declaration before including <stdlib.h>,
11196 as that's closer to how it'll be used.
11198 2003-05-23 Akim Demaille <akim@epita.fr>
11200 * doc/autoconf.texi (Header Portability): ucred.h.
11203 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11205 Overhaul Autotest's logging: generate separate log files
11206 in testsuite.dir/NNN/testsuite.log, and append them to
11207 testsuite.log instead of re-running the test verbosely.
11209 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11210 file descriptor, write 0 to at_status_file instead of setting
11211 at_status=0, initialize some new variables (at_status_file,
11212 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11213 to rerun the tests, instead append the at_group_log to the
11214 at_suite_log when a test fails.
11215 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11216 with the AS_MESSAGE_LOG_FD redirected to stdout.
11217 (AT_CLEANUP): save the output status in $at_status_file
11218 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11219 its original place.
11220 (AT_CHECK): since tests are run with a redirected stdout,
11221 and used to be re-run in verbose mode, turn some $at_verbose
11222 into echo, and don't redirect the output of testing stdout
11225 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11226 the name of the debugging directory and information about
11229 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

11343 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
11346 2003-05-06 Akim Demaille <akim@epita.fr>
11348 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11349 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11350 by aclocal.m4 is changed it might require the importing of another
11351 m4 extension file, i.e., aclocal must be run.
11353 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11354 (&parse_args): Use --force with aclocal if required and supported.
11355 (&autoreconf_current_directory): Use &run_aclocal.

11364 open during the whole autom4te run.
11365 ($icache_file): New.

11368 2003-04-29 Derek Price <derek@ximbiot.com>
11370 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11371 seperator with m4_append_uniq(). It doesn't work.
11372 (AT_CLEANUP): Add `;' to end of at_help_all.
11373 (AT_INIT): Allow --keywords to be specified more than once. When
11374 grepping $at_help_all for keywords, use the field and keyword
11375 seperators to ensure a complete keyword match. Alter at_prev handling
11376 to support the new --keywords behavior.
11378 2003-04-27 Karl Berry <karl@freefriends.org>
11380 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11381 align better with others. I also made some of the individual
11382 entries on one line, for brevity and to make it easier for me to
11383 sort my dir-example file in the Texinfo distribution :).

11448 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
11449 reading the section "Present But Cannot Be Compiled" when the
11450 header causes problems.
11452 2003-03-28 Akim Demaille <akim@epita.fr>
11454 * tests/torture.at (Configuring subdirectories): Require aclocal
11455 1.4, otherwise the test fails, as it does support configure.ac.
11456 This fixes the "test 40 failed" bug reports.
11458 2003-03-28 Akim Demaille <akim@epita.fr>
11460 * doc/autoconf.texi (C Compiler): `#line' portability.

11474 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
11476 2003-03-26 Derek Price <derek@ximbiot.com>
11478 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
11479 obsolete AC_HELP_STRING.
11480 (AC_HELP_STRING): AU_DEFUN to...
11481 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
11482 * tests/m4sh.at (AS_HELP_STRING): New test.
11484 * tests/acgeneral.at: Regenerated.
11486 2003-03-26 Derek Price <derek@ximbiot.com>
11488 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
11489 sense. Verbosify the diversion definitions comment.

11514 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): Normalize
11515 file name for the m4 program, when it has an "exe" file extension.
11516 DJGPP's error messages include the error code in brackets -

11527 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
11528 Tru64 make in the "target lookup" section.
11529 (Automake): Automake 1.5+ no longer requires special tools to be
11530 present on the developer's host.
11532 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
11534 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
11535 to a shell that can handle redirection or quoting correctly.
11536 Override SHELL with the shell detected by configure.
11537 Use of $^O suggested by Tim van Holder.
11538 * bin/autom4te.in (BEGIN): Likewise.
11539 * bin/autoreconf.in (BEGIN): Likewise.
11540 * bin/autoscan.in (BEGIN): Likewise.
11541 * bin/autoupdate.in (BEGIN): Likewise.
11542 * bin/ifnames.in (BEGIN): Likewise.
11544 * bin/ifnames.in: Add final newline to help and version messages.
11546 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
11547 to cope with DOS-style absolute paths, when constructing
11550 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11551 When constructing paths with IFS=:, quote the path. If we're
11552 constructing a DOS-style absolute path, we don't want to split it
11555 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11558 2003-02-25 Pavel Roskin <proski@gnu.org>
11560 * bin/autoheader.in: Add missing newline when printing

11566 2002-09-01 patch by replacing "test -n" with "test -z".
11567 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
11568 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
11570 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11571 to fix a mismatch between example and discussion.
11573 2003-02-24 Kevin Ryde <user42@zip.com.au>
11575 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11576 format starting with "-".
11578 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11580 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11581 is not portable inside Makefile.
11583 2003-02-20 Akim Demaille <akim@epita.fr>
11585 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11586 compiler says yeah, but preproc says nope, compiler is right.
11587 Conversely, prompt the reader to send a bug report to the
11588 maintainers of the package, not of Autoconf.
11590 2003-02-20 Klee Dienes <kdienes@apple.com>
11592 * bin/autoreconf.in (autoreconf_current_directory): Properly
11593 handle an empty aclocal.m4.

11598 $ac_prefix_program.
11601 2002-12-23 Paul Eggert <eggert@twinsun.com>
11603 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11604 innocuous variant befor including <limits.h> or <assert.h>. This
11605 works around a bug reported by Albert Chin: HP-UX 11i
11606 (and earlier versions) have a <limits.h> that declares
11607 gettimeofday and many other functions.
11609 2002-12-03 Paul Eggert <eggert@twinsun.com>
11613 * NEWS, configure.ac: Update version.
11615 * doc/fdl.texi: Upgrade to FDL version 1.2.
11617 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11618 nontrivially in main's body, so that f's external declaration is
11619 not optimized away in AIX. This should fix the bug reported by
11621 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11623 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11624 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11625 defined, to support freestanding compilers. This should fix the
11626 bug reported by Momchil Velkov in
11627 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11629 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11630 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11631 obsolete AC_CHECK_TYPE. The missing empty arg was reported

11633 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11635 * Makefile.maint (www-gnu): New macro.
11636 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11637 the location has moved.

11641 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11642 \(.*\) match is too long and there is something more to be checked.
11643 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11645 2002-11-15 Akim Demaille <akim@epita.fr>

11661 Update from masters.
11663 2002-11-14 Akim Demaille <akim@epita.fr>
11665 * Makefile.maint: Sync with Bison, i.e.:
11666 (po-check): Scan .l and .y files instead of the
11667 .c and the .h files that they generate. This fixes the bug
11668 reported by Tim Van Holder in:
11669 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11670 Look for N_ as well as for _. Try to avoid matching #define for
11674 2002-11-14 Akim Demaille <akim@epita.fr>
11676 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11677 From Paul Eggert and Albert Chin-A-Young.
11679 2002-11-14 Akim Demaille <akim@epita.fr>
11681 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11682 From Paul Eggert and Albert Chin-A-Young.
11684 2002-11-14 Kevin Ryde <user42@zip.com.au>
11686 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11687 than assigning in main, to avoid HP cc +O3 optimizing it away.
11689 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11691 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11692 option. Process --recheck after parsing all options. Pass -q
11693 option to configure on --recheck.
11694 (AC_OUTPUT): Pass -q from configure to config.status.
11695 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11696 arguments to record.
11697 * doc/autoconf.texi (config.status Invocation): Document
11698 config.status -q option.
11700 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11702 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11703 Makefile.in if Makefile.am exists.
11704 (output): Strip `.am' from Makefiles. Don't
11705 output AC_CONFIG_FILES if no Makefiles were found.

11725 Reported by Ezra Peisach.
11727 2002-11-05 Akim Demaille <akim@epita.fr>
11729 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11731 We _have_ to stop using the old compatibility scheme that tried to
11732 avoid useless backslashes because Libtool 1.4.3 contains a
11733 AC_DEFINE([error_t], [int],
11734 [Define to a type to use for \`error_t' if it is not
11735 otherwise available.])
11736 We _have_ to quote the single quote and backslashes with \. The
11737 old compatibility scheme saw that ` was backslashed, and therefore
11738 did not quote the single quote. Hence before this patch, Autoconf
11739 was not compatible with Libtool.
11741 2002-11-04 Paul Eggert <eggert@twinsun.com>
11743 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11758 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
11760 (&autoreconf): here.
11761 ($help, $make, &parse_args, &autoreconf_current_directory):
11763 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11765 2002-10-31 Bruno Haible <bruno@clisp.org>
11767 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

11781 2002-10-31 Akim Demaille <akim@epita.fr>
11783 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
11784 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
11785 Make variable, not a shell variable.
11786 Suggested by Bruno Haible.
11788 2002-10-31 Akim Demaille <akim@epita.fr>
11790 * bin/autom4te.in (load_configuration): Reject #args out of any
11793 2002-10-31 Akim Demaille <akim@epita.fr>
11795 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
11796 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
11797 (_AC_RUN_IFELSE): Use it.
11798 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

11807 Suggested by Tim van Holder.
11809 2002-10-29 Paul Eggert <eggert@twinsun.com>
11811 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
11812 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
11813 Problem reported by Bruno Haible.
11815 2002-10-29 Akim Demaille <akim@epita.fr>
11817 * doc/autoconf.texi (Header Templates): Put also in words what the
11818 pictures says to assist free style readers.
11819 (Customizing autom4te): s/--cache=/--cache /.
11821 2002-10-29 Akim Demaille <akim@epita.fr>
11823 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
11825 sparc_address_test returns void.
11826 Use it with an argument, as prototyped.
11829 2002-10-29 Akim Demaille <akim@epita.fr>
11831 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

12193 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12194 aclocal invocation, as Gettext macros might not be visible to

12198 Reported by Paul D. Smith.
12200 2002-10-08 Paul Eggert <eggert@twinsun.com>

12399 2002-09-13 Akim Demaille <akim@epita.fr>
12401 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12402 (chdir_init) might hang when stat'ing mounted directories.
12403 Reported by Vance Shipley.
12405 2002-09-12 Akim Demaille <akim@epita.fr>
12407 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12410 2002-09-12 Akim Demaille <akim@epita.fr>
12412 * doc/autoconf.texi (Defining Symbols): Present two different
12413 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12414 difference between 1 argument calls, and 2-3 argument calls.
12416 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12418 * doc/autoconf.texi: Review grammar and punctuation.
12420 2002-09-11 Paul Eggert <eggert@twinsun.com>
12422 * doc/autoconf.texi: Fix minor formatting, spelling, and
12424 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12425 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12428 2002-09-11 Akim Demaille <akim@epita.fr>
12430 * doc/autoconf.texi (Questions): Rename as...
12432 (Defining Directories): New.
12434 2002-09-09 Akim Demaille <akim@epita.fr>
12436 * doc/autoconf.texi (Making testsuite Scripts): Update.
12437 Suggested by Nishio Futoshi.
12439 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12441 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12442 plain `@' is wanted.
12444 2002-09-09 Akim Demaille <akim@epita.fr>
12446 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12447 `duplicates', since the algorithm was too naive and could keep
12448 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12449 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12450 Reported by Ralf Corsepius.
12451 * tests/torture.at (Configuring subdirectories): Exercise these
12454 2002-09-09 Akim Demaille <akim@epita.fr>
12456 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12457 looking for a replacement file.
12458 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12459 directory is relative.
12460 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12461 directory definition.
12462 Reported by Andreas Schwab and Jim Meyering.
12464 2002-09-06 Akim Demaille <akim@epita.fr>
12466 * doc/autoconf.texi (Setting Output Variables): Clarify what
12467 precious variables are.
12468 Suggested by Pontus Skoeld.
12470 2002-09-05 Akim Demaille <akim@epita.fr>
12472 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12473 (ifnames, autoscan, autom4te): Since we don't only depend on
12474 configure.ac variables (such as VERSION etc.), but also on prefix
12475 and so forth, depend on Makefile, not configure.ac.
12476 Reported by Alexandre Duret-Lutz.
12477 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12479 2002-09-05 Kevin Ryde <user42@zip.com.au>
12481 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12482 doesn't seem to be confined to ia64, just say "some versions".
12484 2002-09-04 Akim Demaille <akim@epita.fr>
12486 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12488 * Makefile.am (maintainer-clean-local): Remove.
12489 (MAINTAINERCLEANFILES): Remove COPYING.
12491 2002-09-03 Paul Eggert <eggert@twinsun.com>
12493 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12494 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12497 2002-09-03 Akim Demaille <akim@epita.fr>
12499 * configure.ac: Bump to 2.53d.
12500 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12501 as of today, on Automake's team suggestion.
12503 2002-09-03 Akim Demaille <akim@epita.fr>
12507 2002-09-02 Akim Demaille <akim@epita.fr>
12509 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12511 * configure.ac: Disable SITE_MACRO_DIR.
12513 2002-09-02 Jim Meyering <meyering@lucent.com>
12515 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12516 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12517 Also, tweak grammar: s/make sure to/be sure to/.
12519 2002-09-02 Paul Eggert <eggert@twinsun.com>
12521 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12522 directory names are generally preferable to physical names.
12524 2002-09-02 Akim Demaille <akim@epita.fr>
12526 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12527 Reported by Raja R. Harinath.
12528 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12529 * bin/autoupdate.in: Use error instead of die.
12531 2002-09-01 Paul Eggert <eggert@twinsun.com>
12533 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12534 ordinary shell concatenation rather than echo+tr+sed command that
12535 runs afoul of a long-line-related sed bug in Solaris 8.
12537 * bin/autoheader.in (parse_args): --warning -> --warnings.
12539 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12540 stdout, as traditional "ls" does.
12541 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12542 _AC_COMPILER_EXEEXT_O): Likewise.
12543 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12545 * bin/autoconf.as: Add --prepend-include option. This patch was
12546 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12547 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12549 * bin/autoconf.in, configure: Regenerate.
12551 * doc/autoconf.texi (Special Shell Variables): Mention
12552 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12554 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12555 MAILPATH and set PS1, PS2, PS4 to default values, to work
12556 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12557 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12558 the Autoconf documentation specifies; fall back to "unset" only if
12559 this fails. Use a shell for-loop for this rather than an m4 loop,
12560 to shorten the output script.
12562 2002-08-30 Paul Eggert <eggert@twinsun.com>
12564 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12565 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12566 for the CDPATH problem. Document PWD.
12567 (Limitations of Builtins): Document the problem that "cd $foo" and
12568 "ls $foo" may refer to different directories in shells conforming
12569 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12570 example, since the old example is now out of date.
12572 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12573 FOO" and "ls FOO" talk about different directories; this catches
12574 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12577 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12578 of rolling our own unset.
12579 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12580 in practice we needn't worry about CDPATH if unset doesn't work.
12582 * Makefile.in, aclocal.m4, bin/Makefile.in,
12583 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12584 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12585 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12586 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12587 tests/Makefile.in: Regenerate with Automake 1.6.3.
12589 * config/config.guess, config/config.sub, config/mkinstalldirs:
12592 * configure: Regenerate with self.
12594 2002-08-30 Kevin Ryde <user42@zip.com.au>

12604 2002-08-29 Akim Demaille <akim@epita.fr>
12606 * lib/Autom4te/General.pm (&xqx): New.
12607 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12608 hand, which is not portable.
12610 * bin/autom4te.in: Use them.
12611 Use &error instead of die.
12612 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12615 2002-08-17 Paul Eggert <eggert@twinsun.com>
12617 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12618 default list of compilers to try, since it was long ago superseded
12619 by the ksh fc builtin. Suggested by Steven G. Johnson.
12621 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12623 * doc/autoconf.texi (Invoking autom4te): End the option table,
12624 fixing a bug introduced by the previous patch.
12625 (Limitations of Make): Add a 'target lookup' subentry in the
12626 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12628 2002-07-29 Mark D. Roth <roth@feep.net>
12630 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12631 options and use $AUTOM4TE_PATH.
12632 * doc/autoconf.texi: Remove documentation of autom4te
12633 --include-envvar and --site-macro-subdir options and document
12634 use of $AUTOM4TE_PATH.
12635 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12636 arguments from each language section.
12638 2002-07-29 Paul Eggert <eggert@twinsun.com>
12640 * doc/install.texi: Include copyright symbol in copyright notice.
12642 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12644 (AM_MAKEINFOFLAGS): New macro.
12645 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12646 * Makefile.am (INSTALL): Use the new macros.
12647 Use -o rather than --output, since "missing" does not grok --output.
12649 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12651 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12652 comments do not always work. Never trust the exit status of
12655 2002-07-24 Kevin Ryde <user42@zip.com.au>
12657 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12658 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12660 2002-07-23 Paul Eggert <eggert@twinsun.com>
12662 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12663 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12664 apparently treats PATH="nonexistent" as if it contained ".".
12665 Bug reported by Stefan `Sec' Zehl.
12667 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12669 * doc/autoconf.texi (Limitations of Make): Mention the special

12717 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12718 latter was not run.

12886 2002-06-05 Paul Eggert <eggert@twinsun.com>
12888 * config/config.guess, config/config.sub, config/texinfo.tex:
12889 Update from masters.
12891 2002-05-29 Paul Eggert <eggert@twinsun.com>

12921 version of Autoconf that is discussed.
12923 2002-05-22 Paul Eggert <eggert@twinsun.com>
12925 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12926 from the default list of compilers to try. Suggested by
12928 * NEWS: Document the above.
12929 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
12931 2002-05-17 Paul Eggert <eggert@twinsun.com>
12933 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12934 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12935 This improves on an earlier suggestion by H. Peter Anvin.
12937 2002-05-16 Paul Eggert <eggert@twinsun.com>
12939 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12940 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12941 Both macros now accept an optional source-dir arg.
12942 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12944 * NEWS: Document this.
12945 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12947 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12948 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12949 not for GNU extensions; this undoes part of the 2000-11-03 change,
12950 reverting to 2.13-compatible behavior.
12951 Add new optional argument DIR.
12952 (AC_FUNC_FNMATCH_GNU): New macro.
12954 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12956 2002-05-08 Paul Eggert <eggert@twinsun.com>
12958 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12959 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12960 and it causes a 'test' syntax error if it fails.
12961 Bug reported by Stephen Gildea.
12963 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12964 If prototypes are supported, use them to check this at compile-time,
12965 instead of trying to check it at run-time. If we must do a run-time
12966 check, assume that setvbuf is standard when cross-compiling, as
12967 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12968 Bug reported by Paul D. Smith.
12970 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12971 argument specifying location of getloadavg.c. This removes a
12972 FIXME. This idea was taken from Jim Meyering's implementation in
12974 * doc/autoconf.texi (Particular Functions): Document this.
12975 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12976 that's what the code does; this fixes a bug reported by
12979 2002-05-03 Akim Demaille <akim@epita.fr>
12981 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12982 autopoint instead of gettextize.
12983 ($uses_alocal): Rename as...
12984 ($uses_aclocal): this.
12985 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12986 Suggested by Bruno Haible.
12988 2002-05-03 Akim Demaille <akim@epita.fr>
12990 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12992 2002-04-29 Paul Eggert <eggert@twinsun.com>
12994 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12995 files to be 1 second older; just set them to be the same time.
12996 Also, sleep 1 second after the first aclocal, to work around
12997 problems with sub-second time stamps on the input files.
12999 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13001 * doc/autoconf.texi: Mention "set -e -x" lossage
13002 under node "Limitations of Builtins".
13004 2002-04-29 Akim Demaille <akim@epita.fr>
13006 * doc/install.texi: Better wording for setting variables when
13008 From Christian Cornelssen.
13010 2002-04-29 Akim Demaille <akim@epita.fr>
13012 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13013 of lack of $LINENO support, then the test will compare the $LINENO
13014 in testsuite vs. the lineno in the test file. This is wrong, of
13016 Be sure to protect it.
13017 Reported by Patrick Welche.
13019 2002-04-25 Akim Demaille <akim@epita.fr>
13021 * doc/autoconf.texi (Obsolete Macros): Typo.
13022 Reported by Vladimir Volovich.
13024 2002-04-25 Akim Demaille <akim@epita.fr>
13026 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13027 than some of the input files, hence, on the second run of aclocal,
13028 if some of its input are younger, make them older.
13029 Suggested by Paul Eggert.
13031 2002-04-25 Akim Demaille <akim@epita.fr>
13033 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

13038 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
13039 and ac_subst_vars be sh variables containing the list of
13040 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13042 (_AC_INIT_PREPARE): Use them to log them.
13043 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13044 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13045 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13046 _AC_SUBST_FILES and _AC_SUBST_VARS.
13047 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13049 2002-04-24 Akim Demaille <akim@epita.fr>
13051 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13052 autoheader, so that automake does not complain about a missing
13053 config.h.in that was to be created.
13055 2002-04-23 Akim Demaille <akim@epita.fr>
13057 * bin/autoheader.in (parse_args): --warning takes an argument.

13107 Minor spelling and grammar fixes.
13109 * doc/autoconf.texi: Follow the outline suggested in the GNU
13110 Sample Texts sections of the Texinfo 4.2 manual. Most
13111 importantly, this makes sure that the copyright notices appear in
13112 all output formats. You probably need Texinfo 4.2 to generate

13151 workaround for ${1+"$@"}.
13152 * doc/autoconf.texi (Shell Substitutions): Explain it.
13153 From Oliver Kiddle and Peter Stephenson.
13155 Have M4sh perform minimal shell sanitizing.
13157 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13159 (_AS_PREPARE): this new macro.
13161 (AS_INIT): Invoke AS_SHELL_SANITIZE.

13164 Adjust Autoconf and Autotest.
13166 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
13167 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
13168 * lib/autotest/general.m4 (AT_INIT): Likewise.
13169 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
13170 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
13173 Use this M4sh to generate Autoconf's shell scripts.
13175 * tests/wrapsh.as: New, precursor of wrapsh.in.
13176 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13177 on Autotest and M4sh.
13178 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13179 (wrapsh.in): New target.

13195 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
13196 (Portable Shell): Cross reference to Systemology.
13198 2002-04-05 Akim Demaille <akim@epita.fr>
13200 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
13201 directories when descending in a SUBDIRS.
13202 Reported by Ezra Peisach.
13204 2002-04-04 Andreas Schwab <schwab@suse.de>
13206 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13207 contains no literal separators.
13209 2002-04-03 Akim Demaille <akim@epita.fr>
13211 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13212 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13213 Use dnl, not the KILL diversion.
13215 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13216 (AC_CONFIG_LINKS): here.
13218 Don't use the KILL diversion, as it kills spurious output, which
13219 results in failures being hidden.
13220 Use m4_defn where appropriate.
13221 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13222 after the second argument.
13224 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13225 syntax, as it is provided by M4sugar.

13247 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

13265 2002-03-28 Kevin Ryde <user42@zip.com.au>
13267 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,

13270 2002-03-27 Paul Eggert <eggert@twinsun.com>
13272 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

13286 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13287 as POSIX requires, as it doesn't work with Zsh.
13288 * doc/autoconf.texi (Assignments): Document the problem.
13290 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13292 * doc/autoconf.texi (Limitations of Make): Mention more issue
13293 about VPATH, overriding of macros in sub-makes, and handling of
13296 2002-03-21 Paul Eggert <eggert@twinsun.com>
13298 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13299 problem with here-document buffer boundaries.
13301 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13302 when reinvoking the shell, to work around problems with installers
13303 who put strange things like "cd" commands in their environments.

13327 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13328 (Limitations of Usual Tools): Add mkdir section.
13330 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13331 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13332 back on AS_DIRNAME to compute prefixes otherwise; this is
13333 roughly what mkinstalldirs does. That way, we need not have
13334 our own filename disassembler. The old disassembler did not
13335 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13337 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13338 Create at_test_all by a series of assignments,
13339 not by a single assignment of a long string. The latter causes ksh
13340 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13341 presumably because of a buffer overrun.
13343 2002-03-14 Paul Eggert <eggert@twinsun.com>
13345 * lib/autotest/general.m4 (at_times_skip):
13346 Renamed from at_times. Now a boolean.
13347 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13348 says 'times: not found'.

13442 (Hosts and Cross-Compilation): this new section.
13443 * doc/install.texi (System Type): Ditto.
13444 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

13457 2002-03-04 Akim Demaille <akim@epita.fr>

13462 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13463 $*. This is the n-th time I change my mind, but hopefully this is
13466 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13468 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13469 it was only a hack for m4_text_wrap.
13470 (m4_car2): Remove, replaced by...
13472 (_m4_foreach): Adjust.
13473 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

13634 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13635 AUTOTEST_PATH *after* it was set.
13636 Don't put `.' in the PATH: the user should be precise and `./' if
13637 needed. In addition, given that the test suite does some `cd', if
13638 `.' is in the path, the `tested programs' sections will report
13639 programs found in the test suite's directory, while during the
13640 tests (performed in their own directory), these programs are no
13641 longer visible. In other words, the results is confusing and

13718 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13719 and PACKAGE_BUGREPORT from here...
13720 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13722 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13723 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

13865 This patch implements a `long double' suggestion by Oliver Kiddle.
13867 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13868 static, to catch errors if the value isn't known at compile-time
13869 and the compiler supports dynamic arrays. Change its name from
13870 `_array_' to `test_array' to avoid potential name clashes.
13871 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13872 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13873 better than double. Catch a bug in GCC 2.95.2 x86.

13881 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13883 2001-11-13 Akim Demaille <akim@epita.fr>
13885 * lib/autotest/general.m4 (AT_INIT): After having run the test
13886 group, go back to the initial directory, not to at_suite_dir.
13888 2001-11-13 Akim Demaille <akim@epita.fr>
13890 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13891 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13892 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13894 (AT_CHECK_CONFIGURE): Use absolute paths.
13895 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13896 The problem is still the old one: there is no means in M4 (that I
13897 know about) to create a defining macro, because there is no means
13898 to create `$1' etc., therefore, the defining macro ``swallows''
13899 all the arguments meant to the defined macro.
13901 2001-11-13 Akim Demaille <akim@epita.fr>
13903 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13904 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13906 * tests/aclocal.m4: Remove, as it is no longer used.
13908 2001-11-13 Akim Demaille <akim@epita.fr>
13910 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13911 variable names when referring to a single test group, or to
13912 `suite' when referring to the whole test suite.
13913 `at_last_test' is removed: m4 compute at_format itself.
13914 (at_stdout, at_stder1, at_stderr): New variables.
13915 (AT_CHECK): Use them.
13917 2001-11-13 Akim Demaille <akim@epita.fr>
13919 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13921 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13922 Do it as soon as a test fails, don't wait till the end of the test
13924 Don't remove $as_me.[0-9]*, since these files no longer exist.
13926 2001-11-13 Akim Demaille <akim@epita.fr>
13928 * tests/tools.at: Use absolute paths, since we are no longer run
13931 2001-11-13 Akim Demaille <akim@epita.fr>
13933 Now that tests are running in their own private dir, there is no
13934 need to list the files to remove at the end of tests groups.
13936 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13937 (AT_data_files, at_data_files): Remove.
13938 (AT_CLEANUP, AT_DATA): Simplify.
13940 Remove the group dir if !debug && !failed.
13941 * tests/atspecific.m4: Adjust.
13943 2001-11-13 Akim Demaille <akim@epita.fr>
13945 Start a new layout for Autotest: `testsuite' creates
13946 `testsuite.dir' in which the at-check-line etc. files are to be
13947 found, and `testsuite.dir/003' where the test group 3 is run.
13949 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13950 at_check_line_file, at_format, at_test_normalized, at_group_dir
13952 Create the directories.
13953 Use absolute paths for at- files.
13954 (AT_CHECK): Adjust.
13956 2001-11-11 Michael Matz <matz@kde.org>
13958 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13960 (m4_car): Properly quote arguments.
13962 2001-11-13 Akim Demaille <akim@epita.fr>
13964 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13965 with stricter rules on LIBOBJS.
13967 2001-11-12 Paul Eggert <eggert@twinsun.com>
13969 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13970 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13973 2001-11-12 Akim Demaille <akim@epita.fr>
13975 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13977 2001-11-12 Akim Demaille <akim@epita.fr>
13979 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13980 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13981 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13982 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13983 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13984 specify to what the macro should be defined (typically to 1).
13986 2001-11-12 Akim Demaille <akim@epita.fr>
13988 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13991 2001-11-12 Akim Demaille <akim@epita.fr>
13993 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13994 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13995 definition used by Automake where LEX is +/- "${missing} lex" and
13996 `missing' itself contains variables.
13998 2001-11-12 Akim Demaille <akim@epita.fr>
14000 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14001 Now that M4sh pushes BODY, the comments were output at the end of
14004 2001-11-08 Akim Demaille <akim@epita.fr>
14006 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14007 that we can trace macros from aclocal.m4.
14008 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14009 obsoleted, and redirect to the former anyway.
14010 Reported by Ralf Corsepius.
14012 2001-11-08 Akim Demaille <akim@epita.fr>
14014 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14015 processed only if present.
14016 * tests/torture.at (Configuring subdirectories): Use autoreconf
14017 instead of successive calls to autoconf.
14018 Add a nonexistent subdirectory to exercise the patch above.
14019 Reported by Ralf Corsepius.
14021 2001-11-08 Kevin Ryde <user42@zip.com.au>
14023 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14024 doesn't accept .S files.
14026 2001-11-07 Akim Demaille <akim@epita.fr>
14028 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14029 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14030 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14031 * bin/autom4te.in (warn_forbidden): New.
14032 (handle_output): Use it.
14033 Read m4_pattern_forbid with messages.
14035 2001-11-05 Akim Demaille <akim@epita.fr>
14037 * bin/autom4te.in (--normalize): Remove.
14038 * lib/autom4te.in: Adjust.
14040 2001-11-05 Akim Demaille <akim@epita.fr>
14042 * tests/Makefile.am (testsuite): Rename this target as...
14043 ($(TESTSUITE)): this.
14046 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14048 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14049 the --prefix option, also remove it's argument.
14051 2001-11-05 Akim Demaille <akim@epita.fr>
14053 * doc/autoconf.texi (testsuite Invocation): Update.
14054 (Writing testsuite.at): Update.
14056 2001-11-03 Akim Demaille <akim@epita.fr>
14058 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14060 2001-11-03 Akim Demaille <akim@epita.fr>
14062 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14063 (&file_name_is_absolute): New, wrappers around routines from
14065 Use and export them.
14066 (&find_configure_ac): Optionally take a directory where to look at.
14067 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14069 Default @ARGV to `.', not find_configure_ac.
14070 (&autoreconf): Argument is a directory.
14071 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14072 * doc/autoconf.texi (autoreconf Invocation): Update.
14074 2001-11-03 Akim Demaille <akim@epita.fr>
14076 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14077 (@export_forward_subs): New.
14078 Add basename, dirname, and fileparse.
14080 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14081 Don't look for aclocal flags if we already know aclocal is not
14083 Move aclocal.m4t only if it exists.
14084 Reported by Ezra Peisach.
14086 2001-11-03 Akim Demaille <akim@epita.fr>
14088 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14089 passed on command line, defaulting to ./configure.ac if present.
14090 (&maybe_autoreconf, File::Find): Remove, unused.
14091 (&autoreconf): If autoconf is not used, don't try to trace.
14093 2001-11-02 Akim Demaille <akim@epita.fr>
14095 * configure.ac: Bump to 2.52g.
14097 2001-11-02 Akim Demaille <akim@epita.fr>
14101 2001-11-02 Akim Demaille <akim@epita.fr>
14103 * config/config.guess, config/config.sub, doc/standards.texi:
14104 * config/lispdir.m4: Update from masters.
14105 * configure.ac: Bump to 2.52f.
14107 2001-11-02 Akim Demaille <akim@epita.fr>
14109 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14110 Don't run aclocal when aclocal.m4 is not from aclocal.
14112 Don't run libtoolize and gettextize if --install is not given.
14114 2001-11-01 Paul Eggert <eggert@twinsun.com>
14116 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14117 be invoked before _AS_LINENO_PREPARE.
14118 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14119 than character ranges.
14121 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14122 invoking AS_BASENAME. Set the locale variables to 'C' if
14123 possible, as POSIX requires this to get the traditional
14125 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14127 2001-10-31 Paul Eggert <eggert@twinsun.com>
14129 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14130 with {}, as that triggers a bug in Bash 2.05.
14132 (_AS_LINENO_PREPARE): Use Sed rather than
14133 Awk. Fix the sed prepass to work even if there are multiple
14134 instances of $LINENO on the same line. Do not substitute for
14135 other variables like $LINENOT. Do not check file dates; such a
14136 check is unreliable on sufficiently fast machines, and removing
14137 the check makes the code simpler and more reliable. Check for
14138 output and chmod failures.
14140 * doc/autoconf.texi (Special Shell Variables): Document
14143 2001-10-31 Akim Demaille <akim@epita.fr>
14145 * tests/Makefile.am (atconfig): Remove this target, Automake
14148 2001-10-31 Akim Demaille <akim@epita.fr>
14150 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14151 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14152 provided, while it is optional.
14153 * configure.ac: Adjust.
14155 2001-10-26 Paul Eggert <eggert@twinsun.com>
14157 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14158 lib/Autom4te/Struct.pm:
14159 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14162 * doc/autoconf.texi (Special Shell Variables): Document some
14163 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14165 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14166 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14167 eval $LINENO is not portable in practice.
14169 2001-10-24 Akim Demaille <akim@epita.fr>
14171 * lib/Autom4te/General.pm (backname): New.
14173 2001-10-24 Akim Demaille <akim@epita.fr>
14175 * m4/: Remove, merged into...
14178 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14180 * doc/autoconf.texi (Shellology): Mention the problems with bash
14181 2.05's use of ANSI quoting in its `set' builtin.
14183 2001-10-22 Paul Eggert <eggert@twinsun.com>
14185 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14186 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14187 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14188 POSIX decided to standardize on the int flavor of strerror_r.
14189 Always do char* test, as there's no reason not to.
14190 Assign to a char* var, to catch strerror_r that returns int*.
14192 * doc/autoconf.texi (Particular Functions):
14193 Document the above changes. Also, document the fact that
14194 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14196 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14198 2001-10-20 Akim Demaille <akim@epita.fr>
14200 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14201 the executable was missing from the log.
14203 2001-10-20 Akim Demaille <akim@epita.fr>
14205 * lib/Autom4te/General.pm (&update_file): If destination is
14206 unchanged, remove the source.
14207 (&up_to_date_p): Don't be verbose, be debug.
14208 * bin/autoreconf.in: No longer support --m4dir.
14209 (&autoreconf): Display the full path of the configure.ac we are
14211 Trace it only once.
14212 Be sure to honor --force with gettextize.
14213 Always run aclocal.
14214 * doc/autoconf.texi: Adjust.
14216 2001-10-20 Akim Demaille <akim@epita.fr>
14218 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14220 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14221 `intl' is already present, as it refuses unless --force.
14222 (&parse_args): Use -I, --include instead of the old Autoconf
14224 ($localdir, $autoconf_dir): Remove.
14226 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14228 2001-10-19 Jens Petersen <petersen@redhat.com>
14230 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

14237 Don't mention `automatically' in addition to `generated'.
14238 * tests/torture.at (#define header templates): Adjust.
14240 2001-10-19 Akim Demaille <akim@epita.fr>
14242 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
14243 comment, explain how to install automatic mode selection.
14246 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14248 * bin/autoreconf.in (autoreconf): Display the path to the
14249 configure.ac being studied.
14251 2001-10-18 Paul Eggert <eggert@twinsun.com>
14253 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14254 long, to work around a bug in the HP C compiler version HP92453-01
14257 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14258 (AS_BASENAME_EXPR): New macro.
14259 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14260 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14261 and fall back on 'sed' only if the other two fail. This makes
14262 AS_BASENAME act more like AS_DIRNAME.
14263 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14264 contains white space.
14265 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14266 Use AS_DIRNAME, since I think it's now DOS-friendly.
14267 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14268 Allow "dirname //FOO" to return either / or //, as POSIX allows
14271 2001-10-10 Akim Demaille <akim@epita.fr>
14273 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

14277 2001-10-10 Akim Demaille <akim@epita.fr>
14279 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14280 m4_define, since...
14281 (_AS_ECHO_N): AS_REQUIREs it.
14283 2001-10-10 Akim Demaille <akim@epita.fr>
14285 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

14316 * tests/tools.at (AT_CHECK_PERL_SYNTAX): Check autoreconf.
14317 (Syntax of the shell scripts): Don't.

14372 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
14374 2001-10-08 Akim Demaille <akim@epita.fr>
14376 Use `add-log-current-defun-function' for ChangeLog creation.
14377 Suggested by Tom Tromey.
14379 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
14380 (autotest-mode): Adjust.
14381 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

14409 empty, and if we can find a shell that does support LINENO,
14410 then set CONFIG_SHELL to that shell and then re-execute
14411 ourselves with CONFIG_SHELL.
14413 2001-10-05 Paul Eggert <eggert@twinsun.com>
14415 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
14416 doesn't exist. Remove *.tmp, as a .tmp file is created during the
14417 build of $(TESTSUITE).
14419 2001-10-05 Akim Demaille <akim@epita.fr>

14458 compatibility with POSIX shells.

14486 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
14487 Don't use nested parenthesization. This patch was originally

14489 but somehow it didn't get incorporated then.
14490 * doc/autoconf.texi (Limitations of Usual Tools):

14497 Check for `expr' arithmetic overflow, and for compilation failure,
14498 and invoke a new argument $4 if either is discovered.
14499 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14500 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

14533 (AC_PROG_CPP requires AC_PROG_CC): here and...
14534 * tests/fortran.at (GNU Fortran 77): there.
14535 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14536 AC_TRY_RUN is about compilation, not shell commands.

14564 2001-09-23 Akim Demaille <akim@epita.fr>
14566 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
14567 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

14578 * lib/autotest/general.m4: Do not reset AT_victims.
14579 Don't compute at_srcdir nor at_top_srcdir.
14581 * tests/tools.at: Hence use top_srcdir.
14583 * tests/Makefile.am, tests/autoconf, tests/autoheader,
14584 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14586 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,

14638 2001-09-22 Akim Demaille <akim@epita.fr>
14640 * lib/autoconf/autotest.m4: Create `package.m4'.
14641 * tests/Makefile.am (package.m4): Remove.
14643 2001-09-22 Akim Demaille <akim@epita.fr>
14645 Rely on `$LINENO' when possible instead of `__oline__'.
14647 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14648 `$LINENO' support replacement when not supported.
14649 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

14651 (via m4_require). Cosmetic only.

14653 * lib/autoconf/programs.m4: Replace all the occurrences of
14654 `__oline__' with `$LINENO'.
14655 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
14657 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14659 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14660 character (u: -> ue) in a code comment.
14661 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14664 2001-09-21 Akim Demaille <akim@epita.fr>
14666 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14667 Suggested by Jim Meyering.
14669 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14671 * lib/autoconf/programs.m4: Use extensions listed in
14672 $ac_executable_extensions when looking for programs.
14674 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14676 * lib/autoconf/general.m4: Fix a small Englisho.

14679 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14681 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14685 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14686 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14687 be used instead of ':'.
14688 * lib/autotest/general.m4: Replace occurrences of ':' in
14689 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14691 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14693 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14694 arguments. Fixed a typo.
14696 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14698 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14699 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14701 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14703 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14704 * bin/autoupdate.in: Ditto.
14705 * bin/autoheader.in: Reworded a few comments.

14710 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14712 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14713 already have $file). Set output files to binary mode (helps avoid
14714 CR issues on DOSish systems).
14716 2001-09-19 Akim Demaille <akim@epita.fr>
14718 * lib/autotest/general.m4: Englishoes.
14719 From Tim Van Holder and Alexey Mahotkin.
14721 2001-09-18 Paul Eggert <eggert@twinsun.com>
14723 * doc/autoconf.texi (Common Shell Constructs): New node,
14724 documenting AS_DIRNAME.
14725 (Limitations of Usual Tools): Refer to it when discussing dirname.
14726 Also, update discussion of POSIX standard to reflect latest draft.
14728 * lib/autoconf/c.m4:
14729 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14731 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14732 Do not pass a first argument with leading '-'
14733 to expr, by parenthesizing initial integers that might be negative.
14735 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14736 now merely checks whether it is an error to pass an argument
14739 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14740 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14741 whether it is a (compile-time) error to pass an argument to
14742 getpgrp. This simpler test supports the revised documentation,
14743 and is all that AC_FUNC_GETPGRP's users really need.
14745 2001-09-18 Akim Demaille <akim@epita.fr>
14747 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14749 2001-09-18 Akim Demaille <akim@epita.fr>
14751 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
14753 * lib/autotest/general.m4 (AT_INIT): Adjust.
14755 2001-09-18 Paul Wagland <paul@wagland.net>
14757 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14759 Add test for AS_BASENAME.
14760 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14761 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14762 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14763 * tests/base.at: Fixed the expected responses. The old ones were
14765 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14766 the documentation claims it should (and how it behaved in 2.13).
14768 2001-09-18 Akim Demaille <akim@epita.fr>
14770 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14771 the AC_CONFIG_COMMANDS invocation.
14772 This also solves the name clash problems.
14773 Don't set the package's ID.
14774 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14775 No longer to be shipped.
14776 (version.in): Remove.
14777 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14778 * lib/autoconf/status.m4: Adjust.
14779 Use `m4_PACKAGE_STRING'.
14780 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14781 the only optional argument is the name of the test suite.
14782 Expect `package.m4' to define the package signature.
14783 * lib/autom4te.in (Autotest): Add `package.m4?'.
14784 * tests/Makefile.am (package.m4): New.
14785 * tests/suite.at: ifnames is a victim.
14787 2001-09-18 Akim Demaille <akim@epita.fr>
14789 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14790 AC_LIBSOURCE, AC_CONFIG_FILES.
14791 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14792 program version string doesn't match the package's.
14793 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14796 2001-09-17 Paul Eggert <eggert@twinsun.com>
14798 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14799 Allow expression to return any value that can fit into unsigned long
14800 (not int, as before). Check for output errors.
14802 2001-09-17 Bruno Haible <haible@ilog.fr>
14804 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14805 Always include <stdio.h> and <stdlib.h>. Evaluate
14806 the expression in an extra function before these includes. Call
14807 fprintf "%d" only after ensuring the argument is of type 'int'.
14808 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14810 2001-09-17 Paul Eggert <eggert@twinsun.com>
14812 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14813 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14814 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14815 when they don't exist.
14817 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14818 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14821 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14822 version with the version used by fileutils 4.1, except use

15170 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15171 indeed related to running the test suite, while passing

15752 2001-08-10 Akim Demaille <akim@epita.fr>
15754 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15756 Suggested by Russ Allbery.
15758 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15760 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15761 current $prefix to the sub-configures.
15763 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15765 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15766 extension (needed on BeOS). Reported by Guido van Rossum.
15768 2001-08-09 Akim Demaille <akim@epita.fr>
15770 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15772 2001-08-07 Akim Demaille <akim@epita.fr>
15774 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15776 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15777 No need to remove the files before and after the each test, before
15778 each test and at the end of the suite is enough.
15779 Display only the children `times', not the shell's.
15780 If the test failed or was skipped, at-times is not available.
15782 2001-08-07 Akim Demaille <akim@epita.fr>
15784 Always produce testsuite.log, including when there are no
15785 failures. This helps getting information on skipped tests, and
15786 duration of the tests. Err, implement the latter btw.
15788 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15789 Dump information on the first run of each test.
15790 (AT_CLEANUP): Create `at-times' containing the duration of the
15793 2001-08-07 Akim Demaille <akim@epita.fr>
15795 The use of `dumpstat' revealed that `len' was used although it
15796 should not. m4_text_wrap was using it, but in the Autoconf world
15797 where it is legal. Hence (i) test M4sh in its own world, not
15798 Autoconf's, and (ii), ahem, fix the bug :)
15800 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15801 does not like `' instead of [].
15802 (AT_INIT): Forbid `^_?AT_'.
15803 And don't output such tokens.
15804 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15805 `script.as', and `autom4te.cache'.
15806 Remove `empty' and `macro' which are no longer used.
15807 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15808 * tests/m4sugar.at: Use it.
15809 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15811 2001-08-07 Akim Demaille <akim@epita.fr>

15817 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15819 2001-08-04 Akim Demaille <akim@epita.fr>
15821 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15822 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15824 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15825 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15826 (AC_F77_MAIN): Likewise.
15828 2001-08-04 Akim Demaille <akim@epita.fr>
15830 Don't rely on M4sugar outputting the patterns in files, since we
15831 might process the output _without_ running m4, hence without these
15834 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15835 * bin/autom4te.in (@Request::includes): Remove, unused.
15836 (@Request::source): Rename as...
15837 (@Request::input): this.

15842 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15844 2001-08-04 Akim Demaille <akim@epita.fr>
15846 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15847 autoconf', i.e., in addition to caching traces, cache the output.
15849 * bin/autom4te.in (Request::cache): Rename as...
15850 (Request::id): this.
15851 ($cache, $icache, $tcache, $ocache): New.

15860 * bin/autom4te.in ($force): New.
15861 (&parse_args, &print_usage): -f, --force is a new option.
15862 (&handle_output): CPP directives might have spaces after `#'.
15863 (&parse_args): The first file only can be frozen.
15865 2001-08-04 Akim Demaille <akim@epita.fr>
15867 Don't let autom4te compute the `include' traces several times:
15868 first check that the trace cache file is up to date, and then
15869 compare its timestamp with that of the output.
15871 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15872 the preamble. Don't require 5.005 as Autom4te::General does it,
15873 and better yet (use `use', not `require'!).
15874 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15875 Class::Struct as Autom4te::Struct.
15876 * lib/Autom4te/General.pm (File::stat): Use it.
15877 (&mtime): New, export it.
15878 * bin/autom4te.in: Use it.
15879 Declare `$req' is invalid if it is outdated.

15885 must be proposed to the users.

15930 (m4_divert_pop): Dump the whole diversion stack when a diversion
15932 * bin/autom4te.in (&handle_output): Remember of the first
15933 occurrence of a possibly undefined macro, not the last.

15937 * tests/tools.at (autoconf: forbidden tokens, basic)
15938 (autoconf: forbidden tokens, exceptions): No longer sort
15939 autoconf's stderr, as it is now deterministic.
15940 Check that `dnl' is caught.

15963 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15964 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
