1670 Cover more potentially problemtic file names. Use the new
1673 Properly handle funny file names for headers in config.status.
1674 The test suite did not cover this bug because the code was not
1675 quoting properly the arguments of `rm -f' (which "fails" silently)
1676 as well as the arguments of `diff' (whose output was redirected to
1677 /dev/null so we couldn't see its error message).

1793 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
1795 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1797 <DEFAULTS>: Delay computation of variables based on $at_dir...
1798 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1799 <TESTS>: Re-invoke via absolute name, since -C may be in effect.

1823 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1824 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1825 mode, we change to the source directory, also set $ac_pwd so we
1826 do not go back to the build tree for the next config subdir.
1827 * tests/torture.at (Deep Package): Extend test to contain two
1828 config subdirs on the top level.

1859 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1861 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1862 check_SCRIPTS. Building the wrappers for `all' allows help2man

1882 (m4_require): Use m4_do, not m4_join.
1884 Fix some whitespace tests on cygwin.

1904 * tests/base.at (Input/Output): Likewise.
1905 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1906 config.guess, and config.sub to test source tree.

1908 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1909 * tests/torture.at (Substitute a 2000-byte string): Drop
1910 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1911 (Substitute a newline, datarootdir workaround): Likewise.
1912 (Define a newline): Adjust for linenumber changes in configure.ac.
1913 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1922 * tests/m4sh.at (LINENO): Quote $0.
1924 Fix testsuite program wrapper for whitespace in `pwd`.
1925 The problem here is that the usual mantra is that command
1926 variables can contain arguments, thus we cannot just escape
1927 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1928 $top_builddir/tests directory early in $PATH, so that the
1929 wrappers are found by their plain name.
1930 * tests/wrapper.as: Put $testdir early in $PATH.

1943 <at_func_create_debugging_script, Driver Loop>:
1944 Quote $at_group_dir.
1945 * tests/autotest.at (whitespace in absolute testdir): New test.
1947 * lib/autom4te.in: Quote @datadir@.
1949 Proper file name escaping in Autoconf programs and Perl modules.
1950 This includes escaping of characters special to the shell
1951 as well as special to Perl, e.g., leading `<' or `>'.
1952 For example, when $file starts with `>', `open ">$file"'
1953 wrongly tries to append to a different file.
1954 * bin/autoconf.as: Fix quoting for autom4te options.
1955 * lib/Autom4te/General.pm (shell_quote): New function, taken
1956 from coreutils, written by Jim Meyering.

1960 * bin/autoreconf.in (parse_args): Likewise.

1964 * bin/ifnames.in: Likewise, XFile usage fixes.
1965 * tests/tools.at (autom4te and whitespace in file names): Extend
1966 test. Test twice, with special characters allowed on w32, and the
1967 rest. Test leading and trailing whitespace, for `open_quote'.
1968 (autotools and whitespace in file names): New, analogous test.
1969 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1970 by Russ Allbery and Eric Blake.

1974 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.

1976 (update_file, contents): Use it.
1978 * Makefile.am (autom4te-update): Rewrite for git.
1980 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1982 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1984 Fix copyright years.
1985 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1986 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

1996 * doc/Makefile.am (TEXINFO_TEX): Add.
1998 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2000 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2001 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2002 #undef as this runs afoul of our new way of creating config.h.
2003 Problem reported by Jim Meyering in
2004 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

2009 * bin/autom4te.in (files_to_options): Quote active characters

2020 `#AT_STOP_...' line at the end of each test.
2022 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2024 * lib/autotest/general.m4 (AT_INIT): For awk line number
2025 extraction script, ensure `$at_group' has a defined value
2026 even for the empty set, and properly quote its usage inside
2029 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2031 * doc/autoconf.texi (Shell Functions): New chapter. Document
2032 IRIX sh $0 issue in functions, move content from ...
2033 (Portable Shell): ... here.
2034 (Shell Script Compiler): Note that shell functions are not
2035 totally unportable any more.
2037 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2038 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2040 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2041 extracting the line numbers of the last needed test.
2043 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2045 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2048 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2050 Fix IRIX testsuite debugging failures: $0 in functions.
2051 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2052 Do not use $0 inside a function, as IRIX sh will set that to the
2053 function name rather than the script invocation name.
2055 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2056 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2058 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2059 to extract test scripts.
2060 (AT_INIT): Extract and cache test script line numbers.
2062 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2064 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2065 subsequent fixups; the awk -> here-document conversion trashes
2066 performance too much with AIX sh.
2068 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2070 * tests/local.at: Do not test m4, perl with AT_TESTED.
2072 Diagnose and guard against write errors dealing with config.status.
2073 The general idea is this: all write failures from `configure'
2074 writing `config.status' are indicated by $ac_write_error, which
2075 is only checked at the end. This is safe because config.status
2076 code is not executed before the file is complete. Other write
2077 failures, be they inside config.status, or in sub shell/awk
2078 scripts spawned from configure or config.status, typically need
2079 earlier checking, as their results are used right afterwards.
2080 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2081 before writing config.status, check afterwards.
2082 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2083 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2084 Set `ac_write_error' for write failures to config.status. Barf
2085 upon write failures to temporary files.
2086 Adjust note about closing and reopening the here-document.
2087 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2088 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2089 reopening the here-document.
2090 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2091 Ensure `ac_write_error' does not escape into config.status.
2092 Also, add a couple of code paths not yet exercised in the test
2093 suite: a config file with input from stdin, and a config header
2095 Suggestion for catching write errors by Bruno Haible.
2097 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2099 Avoid error with Tru64 awk and testsuite lines with many words.
2100 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2101 reads the testsuite, set the field separator to an unusual value,
2102 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2103 even splits the input if $i, i>0, was never accessed in the script.
2105 Revert 2007-10-17 change.
2106 * TODO: Multiline args in config files and headers mean something
2107 different and are not fixed, see
2108 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2109 Report by Stepan Kasal.
2111 * doc/autoconf.texi (Generic Programs): Fix typo.
2113 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2115 AC_*_TOOL does not canonicalize the prefix
2116 * doc/autoconf.texi (Generic Programs): Do not say that
2117 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2119 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2121 Diagnose write errors in config.status instantiations.
2122 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2123 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2125 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2126 Extend test to also check for some write error failures, using...
2127 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2128 Report by Bruno Haible.
2131 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2133 (_AT_CHECK): Use less indentation, to save space.
2135 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2137 Add witness macro for @top_build_prefix@ substitution.
2138 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2139 (_AC_OUTPUT_FILE): Mention it here.
2141 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2142 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2144 * lib/autotest/general.m4 (at_func_test): Remove.
2145 (AT_INIT): Pre-extract test groups into separate files.
2146 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2147 Remove at-test-source files together with the $at_group_dir.
2148 * tests/autotest.at (Long test source lines): New test.
2150 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2152 Shell functions and variables may share a namespace.
2153 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2156 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2158 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2161 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2163 * lib/autoconf/status.m4: Fix a couple of comment typos.
2165 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2167 2007-11-13 Jim Meyering <meyering@redhat.com>
2169 Clean up the rule to create "expr".
2170 * tests/Makefile.am (expr): Don't redirect directly to target.
2171 Redirect just once, not for each echo statement.
2172 Use $@, not literal "expr".
2174 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2176 Don't worry about preprocessor when testing long long.
2177 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2178 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2179 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2180 These no longer check for preprocessor flaws.
2181 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2182 Do not check for preprocessor flaws.
2184 2007-11-13 Jim Meyering <meyering@redhat.com>
2186 Adapt dependencies, now that a version change doesn't modify configure.ac
2187 * GNUmakefile: Remove "make clean" kludge.
2188 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2190 Don't redirect directly to target.
2191 Use $@, not literal "version.m4".
2193 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2195 * doc/autoconf.texi (Making testsuite Scripts): Document
2196 ":;{" shorthand as in previous patch.
2198 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2200 * doc/autoconf.texi (Limitations of Builtins): Document problem
2201 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2203 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2204 Use ":;{" shorthand.
2205 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2207 2007-11-12 Jim Meyering <meyering@redhat.com>
2209 Add more non-srcdir build support.
2210 * GNUmakefile (dummy): Split a long line.
2211 Add -v option to autoreconf invocation.
2213 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2214 * GNUmakefile (dummy): Remove INSTALL.
2216 Remove racy commands to build scripts in bin/ and tests/.
2217 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2218 are guaranteed to be built, remove the rules that tried to build
2219 them. Before, with a parallel build, these rules could lead to
2220 two processes writing tests/wrapper.in concurrently.
2222 Build in man/ only *after* building in bin/ and tests/.
2223 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2224 in both bin/ and tests/.
2226 Accommodate non-srcdir build-from-checkout.
2227 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2228 Use git's --git-dir=$srcdir/.git option.
2229 Add quotes, in case tarball_version_file contains shell meta-characters.
2230 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2231 * configure.ac: Pass "." to git-version-gen.
2233 Avoid spurious test failures due to version skew.
2234 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2236 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2238 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2239 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2240 Remove conftest.dSYM directory.
2241 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2242 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2243 Remove `conftest.*' recursively.
2244 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2245 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2247 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2249 Report and analysis by Jeff Squyres and Peter O'Gorman.
2251 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2253 Fix typos in variable names.
2254 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2256 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2258 Document that $((expression)) is not portable.
2259 * doc/autoconf.texi (Shell Substitutions): Here.
2261 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2263 Ignore configure --help* errors due to LINENO-impaired shells.
2264 * tests/torture.at (Configuring subdirectories, Deep Package):
2265 In the --help* tests in read-only trees, make `.' temporarily
2266 writable again for the `stderr' file, and ignore errors due to
2267 the attempt to write configure.lineno.
2268 Report by Patrick Welche.
2270 2007-11-10 Jim Meyering <meyering@redhat.com>
2272 Generate package.m4 in build-dir, not srcdir.
2273 * tests/Makefile.am (package.m4): Adjust target.
2274 Don't redirect directly to $@.
2275 (CLEANFILES): Add package.m4.
2276 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2278 When running $(AUTOTEST), search "." before searching $(srcdir).
2280 Avoid a race condition that would make parallel "distclean" fail.
2281 * tests/Makefile.am (distclean-generic): Replace the default,
2282 automake-provided rule with an identical one, but with an additional
2283 dependency on distclean-local. Simply adding the dependency would
2284 cause automake not to emit the rule at all.
2285 * BUGS: Building with -jN works, now.
2287 Distribute git-version-gen.
2288 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2289 since GNUmakefile is distributed, and requires it for dist* rules.
2291 Remove two more generated files from version control.
2292 * INSTALL: Remove generated file.
2293 * lib/autoscan/autoscan.list: Remove generated file.
2295 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2297 * GNUmakefile (PATH): Remove stray apostrophes; they become
2298 part of PATH, which isn't wanted here.
2300 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2302 New config files output variable `top_build_prefix'.
2303 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2305 * doc/autoconf.texi (Preset Output Variables): Document it.
2307 Report by Bob Friesenhahn.
2309 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2310 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2311 function, to parametrize arithmetic with expr vs. the shell.
2312 Use it where possible.
2313 Suggestion by Benoit Sigoure.
2315 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2317 Adjust the documentation of autotest WRT atlocal.
2318 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2319 when using Automake, to write a rule to produce atlocal, since it's
2320 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2321 distributed, not atconfig.in.
2323 2007-11-04 Eric Blake <ebb9@byu.net>
2325 Update list information.
2326 * README: Mention new autoconf-commit list.
2327 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2329 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2331 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2333 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2335 * build-aux/.gitignore: Ignore mkinstalldirs.
2337 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2339 2007-11-03 Jim Meyering <meyering@redhat.com>
2341 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2342 * build-aux/git-version-gen: This syncs from coreutils.
2344 Adjust the build procedure so "make check" works reliably.
2345 * README-hacking: Include an extra step between "make" and
2346 "make check" to ensure that the latter passes.
2348 Use just-built tools, when possible.
2349 * GNUmakefile (PATH): Set and export here, ...
2350 (dummy): ... rather than here.
2352 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2353 and Andreas Schwab <schwab@suse.de>
2355 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2358 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2360 * configure.ac (AC_PREREQ): Require version 2.60, for
2361 AC_PROG_SED, AC_PROG_GREP.
2363 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2364 and Jim Meyering <meyering@redhat.com>
2365 and Andreas Schwab <schwab@suse.de>
2366 and Eric Blake <ebb9@byu.net>
2368 Document a bug in GNU Bash with compound commands and redirections.
2369 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2370 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2373 2007-11-03 Eric Blake <ebb9@byu.net>
2375 Support m4 1.4.5 in testsuite.
2376 * tests/torture.at (Define a newline): Exclude line numbers in
2378 Reported by Ralf Wildenhues.
2380 2007-11-03 Jim Meyering <meyering@redhat.com>
2382 Remove automake-provided files from version control.
2383 * build-aux/elisp-comp: Remove file.
2384 * build-aux/install-sh: Remove file.
2385 * build-aux/missing: Remove file.
2386 * build-aux/mdate-sh: Remove file.
2387 * build-aux/.gitignore: New file.
2388 Suggestion from Ralf Wildenhues.
2390 2007-11-03 Eric Blake <ebb9@byu.net>
2392 Adjust version comparison to account for git snapshot numbers.
2393 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2394 component separator.
2395 * doc/autoconf.texi (Number processing Macros)
2396 <m4_version_compare>: Document this change.
2397 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2399 2007-10-30 Bruno Haible <bruno@clisp.org>
2401 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2402 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2403 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2404 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2405 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2406 Suggested by Paul Eggert.
2408 2007-10-28 Jim Meyering <meyering@redhat.com>
2410 * README-hacking: Autoconf, Automake, and Perl are required to build.
2411 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2413 2007-10-28 Jim Meyering <meyering@redhat.com>
2415 README-hacking: Recommend running autoreconf -vi.
2416 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2417 so that we use just-built tools when they're available.
2418 Suggestions from Ralf Wildenhues.
2420 2007-10-28 Jim Meyering <meyering@redhat.com>
2422 Make inter-release --version output more useful.
2424 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2425 which indicates that it is built using the 19th change set
2426 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2427 is a prefix of the commit SHA1.
2428 * build-aux/git-version-gen: New file.
2429 * configure.ac: Run it to set the version.
2430 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2431 * Makefile.am (dist-hook): Arrange so that .version appears only
2432 in distribution tarballs, never in a checked-out repository.
2433 * .gitignore: Add .version here, too. Just in case.
2434 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2435 not configure.ac, now that the version number changes automatically.
2437 Ensure that $(VERSION) is up to date for dist-related targets.
2438 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2439 git-version-gen doesn't match $(VERSION), but only for dist targets.
2441 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2443 Fix `Deep Package' failure with a configure script early in PATH
2444 * tests/torture.at (Deep Package): Add `.' early in PATH.
2445 Report by Jim Meyering.
2447 2007-10-27 Jim Meyering <meyering@redhat.com>
2449 Remove all generated files from version control.
2450 * aclocal.m4: Remove.
2451 * configure: Remove.
2452 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
2453 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
2454 * README-hacking: New file: how to build from just-checked-out sources.
2456 2007-10-23 Eric Blake <ebb9@byu.net>
2458 Improve corner case of m4_expand.
2459 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
2461 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
2462 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
2465 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
2467 * doc/make-stds.texi: Update from gnulib.
2469 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2470 and Eric Blake <ebb9@byu.net>
2472 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
2473 problem reported by Bruno Haible in
2474 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2476 2007-10-22 Eric Blake <ebb9@byu.net>
2478 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2481 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2483 Don't check for bug in HP-UX 11.00 cpp.
2484 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2485 Use -1ull rather than -1u, since that causes problems with gnulib; see
2486 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
2488 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2490 * tests/autotest.at (Backquote command substitution)
2491 (Multiline backquote command substitution)
2492 (Parenthetical command substitution)
2493 (Multiline parenthetical command substitution): Fix typos in
2496 2007-10-21 Eric Blake <ebb9@byu.net>
2498 * configure: Regenerate.
2500 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2502 Fix config status generation with Tru64 ksh.
2503 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix
2504 escaping of backslash in here-documents.
2506 Fix `Deep Package' test failure on FreeBSD.
2507 * tests/torture.at (Deep Package): Do not add `.' to $PATH
2508 unnecessarily. Do not try running `/bin/sh configure' with a
2509 configure script to be found in $PATH, if the shell does not do
2510 this resolution. Fixes test failure on FreeBSD.
2512 Fix config header generation with AIX awk.
2513 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2514 script, use helper array D_is_set, as `" 0"' does not evaluate
2515 to true for AIX awk.
2517 2007-10-21 Eric Blake <ebb9@byu.net>

3590 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp

3695 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3696 for a.* when searching for executables, as this prevents users

3710 AC_CHECK_TYPE, AC_CHECK_TYPES.
3711 * doc/autoconf.texi (Generic types): C types must be type-names
3712 (the C terminology), not type-ids (the C++ term). C++ types
3713 must not be anonymous.
3714 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3715 for C++; this drops support for anonymous struct and union types,
3716 which were problematic anyway.

3736 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3737 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3738 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3739 works but the latter doesn't, then it's a valid type.
3740 This lets people use function types and so forth.
3741 For C++ there doesn't seem to be a simple solution, so leave it alone.
3742 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3743 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3744 AC_CHECK_TYPE; that wasn't documented or necessary.

3796 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3797 nonstandard grep R.E. escape sequences.
3799 2007-03-17 Jim Meyering <jim@meyering.net>
3801 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3802 (Limitations of Usual Tools): Also list \< and \>, and mention that
3803 HP-UX's grep, like the one from Solaris, does not support that syntax.
3805 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3807 * doc/autoconf.texi (Specifying Names): `--host' does not
3808 change the build type.

3914 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3915 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3916 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3917 substitution will still be done by the special code.
3918 Report by Jim Meyering.
3920 * doc/autoconf.texi (File System Conventions): Mention that
3921 $PATH_SEPARATOR is for the build system only.

3999 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4001 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4002 preprocessor macro arguments in traced name.
4003 * doc/autoconf.texi (Defining symbols): Document longstanding
4004 support for AC_DEFINE-ing macros with arguments, and document
4005 behavior when the same variable has multiple AC_DEFINEs.
4006 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4007 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4008 macros directly, giving much shorter and simpler code.
4010 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4012 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4013 space before "$ac_configure_args" to prevent a 'config.status
4014 --recheck' failure if ac_configure_args doesn't contain a leading
4015 space. This works around a problem with the XEmacs configure.ac,
4016 which uses the (undocumented) ac_configure_args variable
4017 inconsistently with Autoconf.
4019 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4021 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4022 Include <limits.h>, and use its INT_MAX to rewrite the
4023 j loop so that it does not overflow 'int'. Problem reported by
4025 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4026 Play it safe by shifting left by 1 rather than multiplying by 2,
4027 as GCC is less likely to optimize this away when the value
4028 is signed (when it assumes overflow leads to undefined behavior).
4029 Also, don't assume time_t uses two's complement.
4031 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4033 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4034 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4035 dumps core on it. Report by Tim Rice.
4037 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4039 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4040 --disable-option-checking to --help output even when
4041 AC_PRESERVE_HELP_ORDER is not used.
4042 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4043 --with argument, rather than argument with [-.] replaced by
4045 * NEWS: Fix typo in previous change; the news was in the
4048 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4050 * NEWS: Warnings are now generated by default for unknown
4051 --enable-* and --with-* options.
4052 * doc/autoconf.texi (Option Checking): Renamed from
4053 (Configure Option Checking). Tighten up the wording a bit.
4054 (External Software, Package Options): Cross-reference to Option
4055 Checking, and use this to shorten our section.
4056 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4057 "$x" to test "x$foo" != x.
4058 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4059 Don't warn if $enable_option_checking is "no".
4060 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4061 ac_unrecognized_opts to the empty string.
4062 Don't echo the unrecognized opts, as this might mishandle
4063 backslashes or leading -.
4064 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4065 usage next to the other --disable-FEATURE options in the
4068 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4070 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4071 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4072 Print warning for unrecognized --with and --enable options
4073 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4074 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4075 Disable option checking when subdirs are configured.
4076 (AC_OUTPUT): If warnings are enabled, print warning about
4077 unrecognized --with and --enable options at the end of
4078 the configure output (as well as at the beginning).
4079 * doc/autoconf.texi (Option Checking): New node.
4080 Document new option warning functionality.
4082 2006-12-16 Eric Blake <ebb9@byu.net>
4084 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4085 * NEWS: Start news for current version.
4087 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4089 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4090 Define HAVE_GETMNTENT to 1, not to the empty string.
4091 Problem originally reported by Jochen Friedrich in
4092 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4094 This change prompted by a problem report by Andrey Simonenko in
4095 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4096 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4097 object-like macros only, in the traditional portable character
4099 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4100 Warn about attempts to define things that are not identifiers.
4101 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4102 awful hack that AC_DEFINEd macro names containing parentheses.
4104 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4106 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4107 too drastic, even if Texinfo in theory requires it for info mode.
4109 (config.status Invocation): Renamed back from Recreating a
4111 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4112 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4114 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4116 * NEWS: Version 2.61a.
4118 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4119 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4121 * NEWS: Document changes with echo and printf, and the lack
4122 of limits on the total size of multi-line values of substituted
4123 variables, and the AC_FUNC_FSEEKO fix.
4125 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4127 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4128 Writing configure.ac.
4129 (Autoconf Input Layout): Renamed from configure.ac Layout.
4130 (Recreating a Configuration): Renamed from config.status Invocation.
4131 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4132 (acconfig Header): Renamed from acconfig.h.
4133 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4134 (Writing Testsuites): Renamed from Writing testsuite.at.
4135 (Autom4te Cache): Renamed from autom4te.cache.
4137 * BUGS: Remove mention of VPATH problem, since it's now documented
4138 not to be a bug in the Autoconf build procedure itself, but rather
4139 a problem with the proprietary `make' programs.
4141 * doc/autoconf.texi (Build Directories): Add a cross reference
4144 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4145 * doc/standards.texi: Sync from gnulib.
4147 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4148 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4149 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4150 generated automatically.
4152 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4154 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4155 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4156 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4158 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4160 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4161 `CEOF$ac_eof' special marker, the awk script cannot contain a
4162 line matching `^CEOF', so this is not needed any more.
4163 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4164 special marker in the test.
4166 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4168 * tests/tools.at (autom4te preselections): Use `find -newer';
4169 remove one of the sleeps.
4171 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4172 more readable, using ...
4173 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4175 * doc/autoconf.texi (autoheader Invocation): Do not double-
4176 quote the parameter of `AH_BOTTOM' in the example.
4178 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4180 * doc/autoconf.texi (Configuration Headers): Remove the
4181 example with multiple input files.
4182 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4183 multiple input files.
4185 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4187 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4188 creating the awk substitution script, handle one input line at a
4189 time, so that the maximum length of a substituted (multi-line)
4190 value is not limited by the size of the sed pattern space.
4191 The trade-off is a slightly repetitive sed script.
4192 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4193 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4194 * tests/torture.at (Substitute a 2000-byte string): Increase the
4195 test with several long lines, they should not be caught by sed
4198 * tests/tools.at (autom4te preselections): New test, to flag
4199 entries missing from autom4te.cfg.
4200 Report by David Byron <dbyron@hheld.com>.
4202 * tests/torture.at (Substitute a 2000-byte string): Actually use
4203 AC_PROG_AWK, so the last change works as intended.
4204 (Substitute and define special characters): Likewise.
4205 (Substitute a newline): Likewise.
4207 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4208 instead of `awk' consistently.
4209 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4210 * tests/torture.at (Torturing config.status): Test both the
4211 result of AC_PROG_AWK and plain awk.
4212 (Substitute a 2000-byte string): Likewise.
4213 (Substitute and define special characters): Likewise.
4214 (Substitute a newline): Likewise.
4216 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4218 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4219 can be assigned to a function pointer. Problem reported by
4220 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4221 part of a patch by Ralf Wildenhues in that same bug report.
4223 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4225 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4226 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4228 2006-12-01 Eric Blake <ebb9@byu.net>
4230 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4231 cross-compiling from cygwin to mingw.
4232 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4233 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4234 to lib/autoconf/c.m4.
4236 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4238 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4239 string for more reliable failure. Wrap the entire test that
4240 causes the broken Solaris printf to dump core, in a subshell,
4241 so the segmentation fault message is reliably suppressed.
4242 Fix shell expansion errors by using /usr/ucb/echo always;
4243 avoid an error on systems without it by another subshell.
4244 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4245 subshell-$as_echo to `as_echo', for better error message.
4247 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4249 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4250 `BASH_SOURCE' contain a newline, set them to empty, as they may
4253 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4255 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4256 years and is too hard to maintain now. The last straw was
4257 reported by Jerker Baeck in
4258 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4259 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4260 * doc/autoconf.texi (Particular Functions): Move
4261 AC_FUNC_SETVBUF_REVERSED from here...
4262 (Obsolete Macros): ... to here. Say that it does nothing now.
4263 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4264 Turn into (almost) a no-op.
4266 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4268 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4269 These macros are obsolescent and new applications shouldn't need them.
4270 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4271 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4272 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4273 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4274 (AC_FUNC_VPRINTF): Likewise.
4275 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4276 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4277 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4279 * doc/autoconf.texi (Setting Output Variables): Mention that
4280 @VAR1@VAR2 has unspecified behavior. Problem reported by
4282 * NEWS: Mention this.
4284 * Makefile.am: Put only a single '#' into the copyright notice,
4285 so that it's also present in the output file. Standardize wording
4286 in makefile copyright notices to match GNU coding standards.
4287 * bin/Makefile.am: Likewise.
4288 * doc/Makefile.am: Likewise.
4289 * lib/Makefile.am: Likewise.
4290 * lib/freeze.mk: Likewise.
4291 * lib/autoconf/Makefile.am: Likewise.
4292 * lib/autoscan/Makefile.am: Likewise.
4293 * lib/autotest/Makefile.am: Likewise.
4294 * lib/m4sugar/Makefile.am: Likewise.
4295 * man/Makefile.am: Likewise.
4296 * tests/Makefile.am: Likewise.
4297 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4300 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4302 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4303 in the sed script that mangles the awk script: delete up to the
4304 first exclamation mark only.
4305 * tests/torture.at (Substitute and define special characters):
4308 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4310 Rewrite config files generation: avoid quadratic growth in
4311 the number of substituted variables by using awk instead of sed
4312 for the bulk of the substitutions.
4313 * NEWS: Mention this.
4314 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4315 forbidden in the output (and thus input) file.
4316 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4317 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4318 generate just one large awk script for substitutions,
4319 eliminating much of the earlier complexity, while adding some
4320 new complexity. Only expand the substitution templates at
4321 configure time, for smaller configure script size. If
4322 _AC_SUBST_FILES are used, test 'awk' for working getline support
4323 at config.status time. If absent, interpolate through the
4324 shell. The awk script was written with much help
4325 from Paolo Bonzini and Paul Eggert.
4326 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4327 (_AC_SED_FRAG_NUM): Likewise.
4328 (_AC_SUBST_CMDS): Renamed from...
4329 (_AC_SED_CMDS): ...this.
4330 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4331 * tests/torture.at (Substitute a 2000-byte string): Also
4332 substitute a line with 1000 words, and a variable with several
4334 (Substitute and define special characters): Test awk special
4335 characters, and put substitution input strings `@foo@' in the
4336 output, to test that no recursion happens; test several other
4337 combinations from Paolo Bonzini.
4339 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4341 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4342 that replaced echo with AS_ECHO where this wasn't necessary.
4343 Problem reportd by Ralf Wildenhues.
4344 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4345 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4346 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4348 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4350 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4352 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4354 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4355 that traditional Awk lacks 3-arg "split". It has it.
4356 Mention that FS must be a single character, and a few other
4357 99-byte limits of traditional Awk.
4358 Mention that if (i in a) doesn't work with traditional Awk.
4360 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4362 * tests/autotest.at (BSx641-newline in command):
4363 (BS-BS-newline in command, BSx640-newline in command):
4364 (Newline-CODE-BS-newline in command):
4365 (Single-quote-BS-newline in command):
4366 (Single-quote-newline-BS-newline in command):
4367 Use printf '%s\n' instead of echo, for portability to hosts
4368 where echo interprets backslashes. This will break on hosts
4369 that lack printf, but for now let's assume all such hosts
4370 are dead (if not, we should get reports of test failures).
4372 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4374 'echo' has some portability problems, when given a first argument
4375 with a leading '-', or when given any argument containing '\'.
4376 Avoid using 'echo' in these cases.
4377 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4378 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4379 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4380 * lib/autotest/general.m4 (AT_INIT): Likewise.
4381 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4382 argument might be unportable.
4383 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
4384 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
4385 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
4386 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
4387 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
4388 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
4389 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
4390 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
4391 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
4392 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
4393 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):

4397 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
4398 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
4399 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
4400 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
4401 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4402 * bin/autoconf.as: Redo verbose flag implementation, as the old
4403 scheme wouldn't work with AS_ECHO.
4404 * lib/autotest/general.m4 (AT_INIT): Likewise.
4405 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4406 Don't use ECHO_T, since ECHO_N is now reliable.
4407 * lib/autotest/general.m4 (AT_INIT): Likewise.
4408 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4409 rather than using a here-document to put the script into a file.
4410 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4412 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4413 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4414 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4415 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4416 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4417 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4418 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4419 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4420 operand, as AS_ECHO requires. Avoid double file name expansion.
4421 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4422 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4423 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4424 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

4528 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4531 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4533 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4534 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4535 Imported from a similar patch to gnulib by Bruno Haible.

4561 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.

4566 Single-quote in a test title,
4567 Double-quote in a test title): Don't expect failure anymore.
4568 (Backslash in a test title): Put a non-whitespace character after the
4569 backslash so that Bourne shells might actually see it as an escape
4571 (Brackets in a test title,
4572 Pound in a test title,
4573 Comma in a test title,
4574 Quoted Macro in a test title,

4578 Macro with double-quote in a test title,
4579 Macro with backslash in a test title): New tests expected to fail.
4580 * tests/torture.at (#define header templates): M4-quote this title in
4581 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4582 The visible effect was a stray [] in the testsuite output.
4584 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4586 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4587 `trap ... 0' inside a function, for AIX sh.
4589 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4591 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4592 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4593 5363) simply issues a warning when dividing by zero at compile
4594 time. Problem reported by Elias Pipping.
4596 2006-10-26 Eric Blake <ebb9@byu.net>
4599 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4600 show effect on macros that expand with commas.

4625 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4627 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4628 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4629 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4630 reported by Nelson H. F. Beebe for Coreutils 6.4.
4632 * tests/tools.at (autoconf --trace: user macros): Remove test
4633 for tracing multiline macros, since m4 1.4.7a uses a different
4634 way to number lines. Problem reported by Ralf Wildenhues.
4636 2006-10-24 Stepan Kasal <kasal@ucw.cz>

4661 * doc/autoconf.texi (Caching Results): Likewise.
4662 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4663 AC_CACHE_CHECK_INT, since it's no longer public.
4664 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4665 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4696 looking for special shell characters.
4697 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4698 macro defined by AS_VAR_PUSHDEF before passing it as a

4710 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4712 (Imported from Automake.)
4713 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4714 which incorrectly sets the mode of an existing destination
4715 directory. In some cases the unpatched install-sh could do the
4716 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4717 system. We hope this is rare in practice, but it's clearly worth
4718 fixing. Problem reported by Alex Unleashed in
4719 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4720 Also, don't bother to check for -m bugs unless we're using -m;
4721 suggested by Stepan Kasal.

4729 is enabled by default with gnu and gnits strictness.
4730 Report from Bruno Haible.
4732 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4741 Import this change from Gnulib:
4743 2006-09-16 Karl Berry <karl@gnu.org>
4744 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4745 to avoid sectioning errors.
4747 Import these changes from Texinfo:
4749 2006-10-04 Karl Berry <karl@gnu.org>
4750 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

4758 * build-aux/texinfo.tex (\textdegree): New command.
4760 2006-08-12 Karl Berry <karl@gnu.org>

4765 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4767 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4769 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4770 added to the template can get mangled.
4772 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4774 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4775 include the default headers, and redefine obstack_chunk_alloc
4776 and obstack_chunk_free. Fixes false failure with glibc.
4778 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4780 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

4793 the NonStop platform.
4794 * doc/autoconf.texi (Posix Variants): Likewise.
4795 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4797 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4798 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4799 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4800 Use a better substitute, by inspecting the output of "ls"
4801 rather than just using ":".
4802 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4803 rather than AS_EXECUTABLE_P, since we needn't worry about
4804 non-regular files here.
4806 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4807 due to configuration hassles with this. See Tonya Underwood's report
4808 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4819 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4820 initialization which is not inherited through the environment
4821 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4822 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

4827 problems with mkdir -p -m.

4831 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4832 comment about ac_cpp_err; it was incorrect, and anyway
4833 ac_cpp_err is being removed below.
4834 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4835 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4836 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4838 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4839 with werror_flag and conftest.err and so forth. This is more
4840 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4841 and anyway the user shouldn't normally want to see this gorp logged.
4842 Problem reported by Ralf Wildenhues.
4843 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4844 empty, not 'no', since the rest of the code uses 'test -z'.
4846 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4848 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4849 Use a single call to AC_DO_TOKENS rather than multiple, for
4851 (_AC_LINK_IFELSE): Test that resulting file is executable.
4852 Problem reported by mwoehlke in
4853 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4855 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4856 than creating a file to use with test -x; this is much faster.
4858 2006-10-02 Bruno Haible <bruno@clisp.org>
4860 * lib/autom4te.in (Automake-preselections): Add
4861 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4863 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4865 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4866 standard error, `experr' should be used, not `expout'.
4868 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4870 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4871 fseeko testing program twice; just use the earlier result.
4872 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4873 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4874 still doesn't let the program compile.
4875 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4878 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4879 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4880 include it, without including anything else.
4881 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4883 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4885 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4887 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4888 `error.h', and include it, for a `error_at_line' prototype.
4889 Use a nonempty format string in the link test.
4890 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4891 for a declaration of wait3.

4897 can apply to constants too, and that it checks for macro defns.
4898 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4899 and simply cast the identifier to void. This handles structure
4900 values. Problem reported by Ralf Wildenhues.

5375 Require that long long int be at least 64 bits wide. C99 requires
5376 this and enough programs depend on it so we should check for it.
5377 Bruno Haible reports in
5378 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5379 that long long int is 32 bits wide with some nonstandard compilers.
5380 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5382 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5384 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5385 to a nonexistent file, so that we don't have to worry about
5386 a local site configuration that doesn't use /usr/local.
5387 Problem reported by Keith Marshall in
5388 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5390 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5392 * doc/autoconf.texi: Be more consistent about using @acronym with
5393 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5394 quite right (it talked about "OSF/Tru64", even though the
5395 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5396 and it even mentioned "OSF 4"!) and at this point there's little
5397 reason to talk about OSF any more, since it died in 1994.
5398 (Specific Compiler Characteristics): Simplify example of
5399 negative-size array.
5400 (File Descriptors): Reorder to make the text flow better.
5401 Remove joke about "appreciate the various levels"; I didn't get it.
5402 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5403 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5404 (File Descriptors, Limitations of Usual Tools):
5405 Tone down the advice against renaming or removing open files.
5406 (Limitations of Usual Tools): Add a new section, on 'rm'.
5408 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5410 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5411 -lXt in LIBS, idea from Karsten Hopp; this was due since
5414 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5415 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5416 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5417 (which belong to Xt, not X itself). See Debian bug 327655.
5419 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5421 * configure.ac (AC_INIT): Bump to 2.60a.
5424 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5428 * configure.ac, NEWS: Update.
5430 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5432 * config/texinfo.tex: Sync from upstream.
5434 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5435 quadrigraph correctly in traces.
5437 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5440 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5441 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5443 * doc/autoconf.texi (Changed Directory Variables): New node,
5444 to document the whole `datarootdir' business a bit better.
5446 * tests/torture.at (datarootdir workaround): Extend test.
5447 Prompted by report by Alexandre Julliard.
5449 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5451 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5452 when using default mode of IBM C 6 for AIX. Problem and two-line
5453 fix reported by Larry Jones.
5455 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5457 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5458 about literal '${datarootdir}' if a definition is found in the
5461 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5463 * NEWS: Use "M4" rather than "m4" when appropriate.
5464 Problem reported by Eric Blake.
5465 * doc/autoconf.texi: Likewise.
5466 Use @acronym around BSD, GCC, and GNU when appropriate.
5467 (Why GNU M4): Renamed from "Why GNU m4".
5468 (Redefined M4 Macros): Mention that Posix
5469 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5470 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5473 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5475 * bin/autom4te.in (handle_output): Do not forbid the empty
5477 * tests/tools.at (autoconf: the empty token): New test.
5479 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5481 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5482 calls, so that we do not care whether they are LIFO or FIFO;
5483 in the m4_wrap, do not check which diversion is the topmost
5484 one, just check that the stack is balanced at the end.
5485 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5486 base diversion forever--pop the previous diversion before
5487 opening the new one; consequently, remove the m4_wrap call.
5488 * lib/autotest/general.m4 (AT_INIT): Likewise.
5489 * tests/m4sugar.at: Do not use
5490 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5492 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5493 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5495 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5496 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5497 Rework example of m4wrap token-pasting trouble so that it doesn't
5498 care whether it's LIFO or FIFO.
5499 Fix some "contrary to"s that are awkward in English.
5501 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5503 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5504 to `yes' instead of `int$1_t' if the type is found, for more
5505 consistent configure output (where $1 is the number of bits).
5506 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5507 Suggested by Bruno Haible.
5509 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5510 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5511 with system headers. Report by Bruno Haible.
5513 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5515 * config/config.guess, config/config.sub: Sync from upstream.
5517 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5518 in order to avoid picking up an older installed frozen m4sh.m4f.
5519 Besides an outdated shell startup, this could have been created
5520 by an earlier M4 version with incompatible frozen file format.
5522 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5524 * README: Recommend m4 1.4.4 instead of 1.4.3..
5525 * doc/autoconf.texi: Likewise.
5526 (Special Chars in Names): Say that $(.FOO) is portable, as
5527 suggested by Stepan Kasal.
5528 (Installation Directory Variables, Build Directories):
5529 (Automatic Remaking, Subdirectories, Fortran Compiler):
5530 (Making testsuite Scripts, Defining Directories):
5531 Quote variable usages better.
5532 (Making testsuite Scripts): Add clean-local rule to makefile
5533 snippet, by Eric Blake.
5534 (Installation Directory Variables): Fix table item font.
5535 Reword slightly to clarify. Generalize advice about
5536 not using special characters to include all file-related
5537 vars, not just VPATH.
5538 (Special Chars in Variables): Warn about special characters in
5540 (Assignments): Clarify default-value example as suggested by
5542 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5543 (Special Shell Variables): Note leading ./ or ../, as suggested
5545 (Limitations of Builtins): Under cd, warn about CDPATH.
5546 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5549 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5551 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5552 `@var', for texi2html.
5553 (Systemology): Some more word wrapping, for DVI output.
5554 (autom4te Invocation): The short option for `--melt' is `-M',
5557 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5559 * doc/autoconf.texi: More formatting and English tweaks,
5560 many suggested by Ralf Wildenhues.
5561 Reword to avoid "@code{...}'s" and the like, since it's ugly
5562 with Emacs info mode. discontents -> woes.
5563 Put a few "will"s back. time stamp -> timestamp.
5564 side-effect -> side effect.
5566 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5568 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5569 Warn about $@ not persisting. Problem reported by Julien Danjou in
5570 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5571 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5572 Mention other special chars, too.
5574 2006-06-14 Eric Blake <ebb9@byu.net>
5576 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5578 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5580 * doc/autoconf.texi: Some systematic minor improvements, as
5581 follows. Use "makefile" when talking about makefiles
5582 generally (which might be named "makefile" or "Makefile" or even
5583 "foo.mk"), "Makefile" when talking about a specific makefile
5584 called "Makefile". This unclutters the text from weird quotes
5585 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5586 values" rather than "@var{foo}s" and similar constructs containing
5587 "}s". Use "Make rules" rather than "Makefile rules". Minor
5588 English-language improvements. Change the prefix "sub-" to "sub"
5590 Put blank lines around examples more consistently.
5591 Avoid "rather" and "very" as intensifiers.
5592 Avoid "will" as an auxiliary.
5593 (Limitations of Make): Split this node into....
5594 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5595 (Leading _ in Macro Names, Backslash-Newline-Newline):
5596 (Backslash-Newline Comments, Long Lines in Makefiles):
5597 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5598 (obj/ and Make, make -k Status, VPATH and Make):
5599 (VPATH and Double-colon, $< in Explicit Rules):
5600 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5601 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5602 New nodes, resulting from splitup of Limitations of Make.
5603 All cross-references changed. Raise the top node from
5604 a section to a chapter, and all subnodes accordingly.
5605 Redo the introductory wording to match the new organization.
5606 (Installation Directory Variables): Use an example that is
5607 closer to what Autoconf actually does. Mention that VPATH's
5608 value should not contain metacharacters or white space.
5609 (Fortran Compiler): Fix a VPATH bug in an example.
5610 (Leading _ in Macro Names): Mention that this problem is no longer
5611 of practical concern.
5612 (VPATH and Make): Reword the advice to make it clearer
5613 that Autoconf and Automake support VPATH in non-GNU make, but
5614 many packages have bugs in this area.
5615 ($< in Explicit Rules): Refer to Build Directories rather
5616 than using a (non-VPATH-safe) example.
5617 (Automatic Rule Rewriting): Mention the sort of disaster that
5618 can ensue with Solaris-style rule rewriting with VPATH.
5620 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5622 * doc/install.texi (Compilers and Options): Weaken the
5623 suggestion to use GNU make for VPATH builds.
5625 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5626 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5628 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5629 in regular expression.
5631 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5633 * doc/autoconf.texi (Installation Directory Variables):
5634 Drop extra @samp from `@table @samp' item.
5635 (Limitations of Usual Tools): Comment fix.
5636 Do not nest @samp just to point to other table items.
5637 (Writing testsuite.at) <AT_CHECK>: The second argument to
5638 `@dvar' is already @samp'ed.
5639 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5640 do not use @var in the second argument.
5642 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5644 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5645 $as_shell.exe too. Problem reported by Andreas Buening in
5646 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5648 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5650 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5651 `unused variable' compiler warning, for `-Wall -Werror'.
5652 Reported by Jaap Haitsma in
5653 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5655 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5657 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5658 case the compiler dumps core. Problem reported for
5659 OpenServer 5.0.7 by Tim Rice in
5660 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5661 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5664 2006-06-06 Tim Rice <tim@multitalents.net>.
5666 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5667 "ERROR" only shows up in "make check" output if there is an

5672 * tests/tools.at (automatically allowed tokens): Fix typo.
5674 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5676 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5678 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5679 typically overflows on x86 CPUs, even though the C standard
5682 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5684 * configure.ac (AC_INIT): Bump to 2.59e.

5691 * config/texinfo.tex: Sync from upstream.
5693 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5694 seen, invoke libtoolize with `--ltdl' argument.
5695 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5697 Suggested by Eric Blake.
5699 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5701 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5702 reported by Ralf Wildenhues.

5715 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5716 message issued by AC_REQUIRE.
5717 * tests/m4sugar.at: Check m4_require's error message.
5718 * tests/base.at: Check AC_REQUIRE's error message.
5719 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5721 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5723 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5724 `expout' as the last parameter.
5725 * tests/tools.at: Adapt to the above change.
5727 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5729 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5730 information about race-free implementations of mkdir.

5739 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5741 * NEWS: GNU make now recommended for VPATH builds.
5742 Mention that some macros are now documented to be obsolescent.
5743 * doc/autoconf.texi:
5744 Prefer "current" to "modern" to describe
5745 currently-used (albeit perhaps old-fashioned) hosts.
5746 Mention which ancient features no longer need to be worried about.
5747 setgid -> set-group-ID
5748 setuid -> set-user-ID (these are the Posix terms)
5749 Fix some misuses of "only".
5750 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5751 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

5761 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5762 Mention that it's now safe to use 3 and 4.
5763 (Limitations of Usual Tools): cp -r is now specified by Posix.
5764 Omit longwinded and obsolescent discussion of cp -f.
5765 Modernize discussion of expr, ls.
5766 (Limitations of Make): Modernize discussion of VPATH builds.
5767 Mention $? as a workaround in some cases.
5768 * doc/install.texi (Basic Installation):
5769 Mention "./configure; make; make install" first. Be more
5770 specific about why this file is generic. Remove unnecessary
5771 parens. Remove misleading "only". Remove obsolete advice
5772 about csh. Don't say "configure" takes awhile; say it
5773 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5774 and CC=c99 rather than CC=c89, as these are blessed by current
5775 Posix. Recommend GNU make if doing a VPATH build.
5777 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5779 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5780 examples involving shell prompts.

5798 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5800 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5801 about quoting the case statement, just in case.

5819 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5821 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5822 about quoting ac_try: quote all of it, if any of it seems suspicious.
5823 This means we don't have to worry about ${ or sed any more.
5824 Also, double-quote the case statement, to work around misuses via
5825 underquoting as reported by Ralf Wildenhues in
5826 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.

5841 since evidently some packages rely on the old, broken behavior.
5842 Problem reported by Ralf Wildenhues in
5843 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5844 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5845 pre-2006-05-26 definitions, but leave in the comments that
5846 these macros are dangerous and should not be used.
5847 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5848 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5849 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5850 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5851 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5853 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5855 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5856 the use of 'tr', since this is our only use of 'tr'.
5858 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5859 and Paul Eggert <eggert@cs.ucla.edu>
5861 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5862 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5864 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5866 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5867 the output file in the `${datarootdir}' test.
5869 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5870 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5872 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5873 mention of `datarootdir' in the input file(s), but literal
5874 `${datarootdir}' in the output file, and we haven't warned yet,
5875 then warn as well: the user may have (erroneously) used
5876 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5877 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5878 * tests/torture.at (datarootdir workaround): Extend this test.
5881 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5882 and Paul Eggert <eggert@cs.ucla.edu>
5884 * doc/autoconf.texi (autoheader Invocation): The first argument to
5885 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5886 alternatives and clear up the language a bit.
5888 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5890 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5891 ac_config_guess, ac_config_sub, ac_configure.
5892 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5893 Fix typo that prevented an unnecessary space from being removed.
5894 Problems reported by Ralf Wildenhues in:
5895 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5897 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5899 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5900 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5901 Don't use the term "thread-safe" to talk about mkdir race
5902 conditions, since the problem is more a process than a thread
5903 issue. Problem reported by Stepan Kasal in:
5904 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5905 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5906 the test for 'install' more closely. Look at MKDIR_P first.
5907 Look in the PATH, and at /opt/sfw/bin.
5908 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5909 Don't bother to try mkdir -p, since we already check mkdir --version;
5910 just look at the version number. (There's no easy way to check
5911 for race-free implementations.)
5912 * tests/tools.at (autoconf: subdirectories): Adjust to above
5913 changes, since MKDIR_P now might end in "/mkdir -p".
5915 * doc/autoconf.texi (autoheader Invocation): Mention that the
5916 first arg of AC_DEFINE_UNQUOTED must be a literal.
5917 Problem reported by Ben Pfaff in
5918 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5920 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5921 * doc/autoconf.texi (Special Chars in Variables): New section.
5922 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5923 (Installation Directory Variables): Quote $(datadir) better.
5924 (Limitations of Builtins): Describe some of eval's trickiness.
5926 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5927 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5928 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5929 in front of every arg, not just trailing args. Quote apostrophes.
5930 (_AC_EVAL_ECHO): New macro.
5931 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5932 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5934 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5935 exposed by quoting of eval argument. Put the command on line line
5937 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5938 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5939 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5940 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5941 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5942 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5943 Use eval more safely.
5944 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5945 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5947 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5948 lines, exposed by quoting of eval argument.
5950 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5951 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5953 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5954 initialization of `ac_cv_exeext', do not override it if it was
5955 already set, unless it was set to `no', for compatibility with
5956 Autoconf-2.13, and comment this.
5957 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5958 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5959 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5960 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5961 Document that this test may be overridden by setting
5964 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5966 Revert these two patches:
5968 2006-04-06 Eric Blake <ebb9@byu.net>
5969 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5970 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5973 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5974 Clean up _AC_COMPILER_EXEEXT* macros.
5975 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5976 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5977 ac_file to the name of the default output file and call
5978 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5979 initial `rm' of the candidate files...
5980 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5981 the same list in subsequent `rm' calls, and for the temporary
5982 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5983 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5984 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5985 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5986 no longer needed) by libtool. Make it a cache check.
5987 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5988 copied here by mistake.
5989 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5990 _AC_COMPILER_EXEEXT.
5991 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5992 _AC_COMPILER_OBJEXT directly.
5993 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5995 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5997 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5998 Fix description of how the buggy `sed' works.
6000 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6004 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6005 ENOLCK. Only mention `make -j' when applicable. Only raise
6006 fatal errors when `make -j' is involved. Improve error message.
6008 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6010 * doc/autoconf.texi (Here-Documents): We now know more about
6011 the variable expansion in here documents bug.
6012 Thanks to Tim Rice and Stepan Kasal.
6014 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6015 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6017 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6019 * tests/autotest.at (Multiline command from M4 expansion):
6020 No failure to be expected if the shell quotes newlines in
6021 commands in the `set -x' output. Report by Tim Rice.
6024 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6026 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6027 expansion in the here-documents used by config.status, as that
6028 runs afoul of the Korn shell version M-12/28/93d bug described in
6029 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6030 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6031 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6033 2006-05-23 Jim Meyering <jim@meyering.net>
6035 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6036 Fix typo introduced with 2006-04-02 change. It reversed the sense
6039 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6041 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6042 ac_dB slightly, to save bytes in the script.
6043 Max out at 50 lines, rather than 96; this is more likely
6044 (though not guaranteed) to avoid obscure 'sed' failures.
6046 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6048 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6049 `tr -d -' as bad option argument. Work around this by deleting
6050 an unrelated character.
6051 Report by Tim Rice <tim@multitalents.net>.
6053 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6054 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6055 Stepan Kasal <kasal@ucw.cz>
6057 * doc/autoconf.texi (Particular Programs): Do not promise that
6058 we always prefer the GNU version of the program, and that we
6059 search according to PATH; both rules can have exceptions.
6060 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6061 AC_PROG_SED. Move descriptions of limitations
6062 to the Limitations of Usual Tools section.
6063 (Limitations of Usual Tools) <sed>: Mention script length
6064 limitations with Solaris /usr/ucb/sed.
6065 <grep>: Fix wording for empty alternative. Mention that -c and
6066 -l should not be combined, and that -E and -F should not be
6069 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6070 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6072 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6073 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6075 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6077 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6078 AC_DEFINE is now passed to m4_pattern_allow.
6079 * NEWS: Mention that; likewise for AC_SUBST.
6080 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6081 the parameter to m4_pattern_allow.
6082 * tests/tools.at: Add a check for that.
6084 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6086 * lib/autoconf/status.m4: Fix typos.
6088 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6090 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6091 only the files that this macro generates.
6093 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6095 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6096 the HP-UX sed limitation of 99 commands, labels do not count.
6097 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6099 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6101 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6103 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6104 Import the following fix from coreutils:
6106 2006-01-13 Jim Meyering <jim@meyering.net>
6108 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6109 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6110 not double-quote uses of that variable, to accommodate the rare
6111 case in which getmntent is available in none of the libraries
6112 checked. This happens at least on FreeBSD 5.0.
6114 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6116 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6117 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6118 some other programs unwisely rely on these undocumented vars.
6119 But put in warning comments about them.
6120 Problem reported by Ralf Wildenhues in
6121 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6122 * NEWS: Document that these variables are intended to go away.
6124 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6126 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6127 and set the language to C++ (analogous to the equivalent Fortran
6130 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6131 * doc/autoconf.texi (C++ Compiler): Document it.
6132 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6135 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6137 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6138 that caused config.status to generate 100-command sed scripts; the
6139 portable limit is 99.
6141 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6143 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6144 variable `ac_d' instead of `d' to avoid infringing namespace.
6145 Report by Ralf Menzel.
6147 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6149 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6150 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6151 * tests/tools.at (autoconf: subdirectories): New test, taken from
6152 the corresponding problem report by Ralf Wildenhues in:
6153 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6155 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6156 Quote some uses of shell variables if they might suffer unexpected
6157 globbing. This doesn't fix all instances of quoting problems that
6158 I found, just the easy ones that look safe.
6159 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6160 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6161 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6162 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6163 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6164 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6165 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6167 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6168 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6170 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6172 * bin/autoreconf.in ($help): Reword according to the manual.
6173 Suggested by Olly Betts.
6175 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6176 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6178 * bin/autoreconf.in: Pass the directory argument to
6179 `require_configure_ac'. Fix comment.
6180 * tests/torture.at (Configuring subdirectories): Expose this.
6181 Reported by Olly Betts.
6183 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6185 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6186 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6187 Automake as follows:
6189 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6190 `$configure_in' instead of `configure.in', to preserve
6191 directory component.
6193 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6195 * config/config.guess, config/config.sub, config/texinfo.tex,
6196 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6198 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6200 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6201 test for C99 conformance; (bool) 0.5 is an integer constant
6202 expression, but (bool) -0.5 is not. Problem reported by Fedor
6203 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6205 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6207 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6208 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6209 Warn about obsolete install-sh files. Remove stray sentence
6210 fragment and fix cross reference.
6211 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6212 install -d; this undoes the 2006-05-10 change.
6213 (MKDIR_P): Mark with AN_MAKEVAR.
6214 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6215 that we don't require $INSTALL to be thread-safe. Move comments
6216 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6217 of AC_PROG_INSTALL. Output a message saying that we're checking
6218 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6219 MKDIR_P instead of AC_SUBST.
6220 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6221 Special magic for MKDIR_P, too.
6222 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6224 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6226 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6228 Sync from Automake, as follows:
6230 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6231 * config/install-sh: Initialize IFS, so field splitting isn't
6233 * config/mkinstalldirs: Likewise.
6234 * config/missing: Remove superfluous quotes. Replace all uses of
6235 `[' by `test', for consistency, and for..
6236 * config/missing (sed_minuso, sed_output): New variables.
6237 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6238 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6239 Fixes `missing' to detect `--output' for help2man. Fixes
6240 PR automake/483. Report by Dennis J. Linse.
6241 (autom4te): Document in `missing --help'.
6243 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6245 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6246 * config/install-sh: Don't use 'path' to talk about file names,
6247 as per GNU coding standards. Close a race condition reported by Ralf
6248 Wildenhues and Stepan Kasal. There is still a race condition
6249 on hosts that predate Posix 1003.1-1992, but we can't help this.
6250 Don't mishandle weird characters like space on pre-Posix hosts.
6251 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6252 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6253 AC_PROG_MKDIR_P from AS_MKDIR_P.
6254 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6255 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6256 earlier editions are not (including Automake 1.8.3).
6257 Do not suggest mkinstalldirs for thread-safety.
6258 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6259 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6260 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6261 presence of special characters and race conditions.
6262 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6263 in Autoconf's name space.

6266 and Paul Eggert <eggert@cs.ucla.edu>
6268 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6269 from Automake with minor changes.
6270 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6272 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6274 * config/install-sh: Update to Automake CVS version, as follows:
6275 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6276 * lib/install-sh: Simplify the expr implementation of dirname.
6277 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6278 * lib/install-sh: Handle --, and diagnose unknown options.
6280 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6282 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6283 `./autom4te' to create `./testsuite', since the `all' target
6284 will ensure its presence, but `installcheck' should not create
6285 the uninstalled wrappers.
6287 * tests/torture.at (Unusual Automake input files): Skip if we
6288 detect automake < 1.8.
6290 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6292 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6293 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6294 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6297 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6299 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6300 munge (multiple) white space and other oddities.
6301 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6302 single quotes in variable assignment.
6303 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6304 and similar failures by adding multiple spaces, tabs, and other
6306 Report and different test suggested by Francesco Romani
6307 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6309 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6310 single quotes, we only need to search for single quotes; this
6311 both simplifies the search pattern, and makes us less
6312 susceptible to `echo' variations for arguments not containing
6314 (_AC_ARG_VAR_VALIDATE): Likewise.
6316 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6318 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6319 `$*' and IFS concatenation issue with traditional shells and

6324 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6325 precisely which Mac OS X versions have the od problem.
6327 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6329 * doc/autoconf.texi: Use @option systematically.
6331 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6332 and Bruno Haible <bruno@clisp.org>
6334 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6336 (Integer Overflow): Mention the special case of integer division
6339 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6341 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6342 traditional shells like the Solaris one that do not use the
6343 first IFS character for assembling `$*'.
6344 Prompted by a related report from autoconf_bug@nro.ca.
6346 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6347 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6355 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6357 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6358 in URLs to improve DVI formatted output (requires texinfo 4.6).

6368 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6369 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6370 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6372 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6374 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6377 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6380 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6382 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6383 /bin/sh set unsorted output.

6390 (Integer Overflow, Null Pointers, Buffer Overruns):
6391 (Floating Point Portability, Exiting Portably): New sections.
6392 (Writing Test Programs): Fix some langauge. Recommend exiting
6393 with status 1, not merely nonzero. Clarify exit declaration.
6394 (Run Time): Move C exit status stuff to new Exiting Portably section.
6395 (Systemology): Mention Posix and levenez. Update v7 reference.
6396 (Portable Shell): Mention the Posix shell.
6398 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6400 * bin/autoconf.as (me): Replace by as_me.
6402 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6404 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6405 since as_me isn't set yet.
6407 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6409 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6410 a few minor bugs in this area.
6412 * doc/autoconf.texi (Programming in M4sh): Comment out the
6413 documentation of AS_BASENAME, for now.
6414 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6415 (Limitations of Builtins) <basename>: Do not refer to
6417 * bin/autoconf.as (me): Don't use AS_BASENAME.
6418 (dir): Remove the unused variable.
6419 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6420 AS_DETECT_REQUIRED. All uses changed.

6428 (_AS_DIRNAME_PREPARE): Likewise.
6429 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6430 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6431 (AS_DIRNAME): Use "dirname --".
6433 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6435 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6436 of "run time" and "run-time" changed to "runtime", for consistency.
6437 * lib/autoconf/fortran.m4: Likewise (in comment).
6438 * lib/autoconf/functions.m4: Likewise.
6439 * lib/autoconf/general.m4: Likewise.
6440 * lib/autoconf/headers.m4: Likewise.
6442 * doc/autoconf.texi (Run Time): Document the exit status situation
6443 with more accuracy and detail.
6445 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6447 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6448 Archive is not officially `GNU' any more. Update URL.
6449 (Defining Directories): Likewise
6450 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6452 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6454 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6455 newline from the `trap' code to finish `config.log'; the NetBSD
6456 /bin/sh resets the exit status after an empty command, as
6457 documented in doc/autoconf.texi.
6458 Reported by Dalibor Topic <robilad@kaffe.org>.
6460 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6462 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6463 Suggested by Bruno Haible.
6465 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6467 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6468 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6469 Instead, just list the shells that we know work.
6470 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6471 changed. Be more cautious about the _cv_ variable.
6472 * tests/tools.at (Syntax of the shell scripts): Check the
6473 _cv_ variable once, at first, to avoid an internal autoconf error
6474 when sh -n does not work.
6476 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6478 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6480 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6482 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6483 use ">&-" since we're only 99.999% sure that this is portable,
6484 and since the MinGW bug is fixed in a different way.
6485 * lib/autotest/general.m4 (AT_INIT): Likewise.
6487 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6489 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6490 before opening config.log, to avoid hitting a bug on MinGW.
6492 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6494 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6495 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6496 This works around a MinGW bug reported by Eric Paire.
6497 Make sure that all writes to the log file append to it,
6498 rather than possibly losing data.
6499 * lib/autotest/general.m4 (AT_INIT): Likewise.
6501 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6503 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6506 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6510 * configure.ac (AC_INIT): Bump to 2.59d.
6512 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6516 * Makefile.maint (news-date-check): Do not require a leading `*'
6517 before the release date in NEWS.
6519 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6520 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6522 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6523 the instantiated file do not contain the string 'datarootdir'
6524 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6525 @mandir@, replace the reference '${datarootdir}' by the value.
6526 * tests/torture.at (datarootdir workaround): New test.
6527 * NEWS: Advertise this temporary fixup.
6528 Based on a patch by Bruno Haible, reported and analyzed by
6529 Paul Eggert and Noah Misch.
6531 2006-04-12 Eric Blake <ebb9@byu.net>
6533 * tests/autotest.at (Debugging a failed test): Fix comment.
6535 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6537 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6538 all the changes since 2006-04-07.
6540 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6542 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6543 succeeded, but `ln -s file dir' failed, take care to remove the
6544 leftover target before the next test, to prevent its spurious
6545 failure; also make sure `ln file dir' works before selecting it.
6546 Thanks to Keith Marshall for pointing this out.
6549 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6550 assignments in `at_debug_args', so that we put them correctly
6551 in the `run' script.
6552 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6553 Reported by Eric Blake.
6555 2006-04-11 Eric Blake <ebb9@byu.net>
6557 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6558 top-level tests after micro-suite has been run. Used in...
6559 (Debugging a successful test, Debugging script and environment),
6560 (Debugging a failed test): ...these new tests. The first of these
6562 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6563 macro, split out from...
6564 (AT_INIT): ...here, so that using -d also generates a run script.
6565 Document that -d inhibits top-level logging.
6566 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6567 inhibits top-level logging; debug scripts are created.
6569 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6571 * tests/autotest.at (Empty test, Empty check): New test to check it.
6573 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6576 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6578 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6579 the files if a problem appears. Make the empty *.at files
6580 read-only, too. Proposed by Ralf Wildenhues.
6582 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6584 * config/Makefile.am: Add comment to force updated Makefile.in.
6586 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6587 space only patch to this file, this patch causes the Makefile.in
6588 files that include freeze.mk to be updated, and thus have a
6589 newer time stamp again, which in turn makes a pristine CVS
6590 checkout have correct time stamps.
6592 * Makefile.maint (cvs-sv): New macro, to be used..
6593 (config.guess-url_prefix, config.sub-url_prefix)
6594 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6595 point to CVS text checkout of Gnulib files.
6596 (copyright-check): Bump current year.
6597 (announcement): Do not hard-wire `./announce-gen'.
6598 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6600 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6602 (wget_files): Update config.guess, config.sub, texinfo.tex by
6603 `wget-update', now that their URLs work again.
6605 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6607 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6608 Problem noted by Paul D. Smith.
6610 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6612 * doc/autoconf.texi: Remove unused words from word list.
6613 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6614 .x-sc_trailing_space: New files.
6616 * doc/standards.texi: Sync from gnulib.
6618 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6619 `LIBOBJDIR' as experimental.
6621 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6622 with a target directory; it's internally implemented as `cp'
6623 anyway, but since Autoconf advertises the possibility to use
6624 a target directory when LN_S is `ln -s', we need to find out.
6625 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6626 analyzed by Keith Marshall <keith.marshall@total.com>.
6630 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6632 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6633 confdefs.h as-is. In general, if it has backslash-newline or the
6634 like, then it doesn't work either to sort or to remove empty
6637 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6639 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6641 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6643 * lib/autom4te.in (Automake-preselections): Preselect
6646 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6648 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6649 apostrophe within a single-quoted string, as this is the usual
6650 tradition and is easier to read than '"'"'. Don't rely on the
6651 shell treating "$/" like '$/'. Use a more-consistent indenting
6654 2006-04-09 Eric Blake <ebb9@byu.net>
6656 * tests/autotest.at (Backquote command substitution),
6657 (Multiline backquote command substitution): Remove mistaken
6658 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6660 (Parenthetical command substitution, Multiline parenthetical
6661 command substitution): here.
6663 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6665 Import macros from gnulib (often changing their name).

6696 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6697 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6698 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6699 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6700 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6701 (Coding Style). Don't mention m4_expand_once.

6741 _AS_DETECT_BETTER_SHELL:
6743 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6744 skip nonexistent directories.
6745 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6746 only shell candidates which exist.
6747 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6748 * lib/autotest/general.m4 (AT_INIT): No need to give three
6749 parameters to _AS_PATH_WALK.
6751 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6752 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6754 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6755 distinguish m4sugar macros.
6756 * tests/tools.at (autoupdating with aclocal and m4_include):
6757 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6758 test case by Noah Misch <noah@cs.caltech.edu>.
6760 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6762 Revert my change from 2006-03-17, in other words:

6769 2006-04-07 Eric Blake <ebb9@byu.net>
6771 * doc/autoconf.texi (Programming in M4sh): Document that
6772 AS_MKDIR_P exits the script on failure.
6773 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6775 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6794 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6796 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6797 whether `set' quotes correctly: redirect stderr of the tested
6798 `set', and use a subshell, for Ultrix; use `sed' instead of
6799 `grep' for zsh `set' which may write binary output; match only
6800 at the beginning of a line, to avoid false positives.
6801 In order to avoid false positives by unrelated variables with
6802 multiline content, put the dump algorithm in a subshell and
6803 unset all variables containing newlines (except some which are
6804 special to the shell). Warn about cache variables that are

6850 ac_config_<foo>s again, sometimes normalized, sometimes not.
6851 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6852 (AC_CONFIG_COMMANDS): Do not do so here.
6853 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6854 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6855 2005-07-25 rewrite. Noticed by Noah Misch.
6857 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6858 _AC_PRESERVE_HELP_ORDER, ...

6861 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

6864 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6865 for --help from Cygnus `configure.'
6867 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6909 normalizing it, consistent it with previous releases.
6910 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.

6915 Use simplified args that Eric Blake originally suggested.
6917 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6919 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6920 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6921 Use 'comm' rather than N instances of grep; this also fixes a bug
6922 whereby substrings were incorrectly matched, causing us to not
6923 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6924 (exclude_list): Exclude empty macros.
6925 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
6927 Use awk rather than grep -E or egrep, to avoid

7008 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
7009 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
7010 ac_file to the name of the default output file and call
7011 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7012 initial `rm' of the candidate files...
7013 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7014 the same list in subsequent `rm' calls, and for the temporary

7017 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7018 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7019 no longer needed) by libtool. Make it a cache check.

7021 copied here by mistake.

7716 CONFIG_SHELL in the environment of the configure rerun.
7717 * doc/autoconf.texi (Here-Documents, config.status Invocation):

7740 Factor functionality to..
7741 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7742 `AC_SUBST($1)' in the public version.
7743 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7744 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

7769 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7770 conftest.o, to see whether the compiler really obeys; rm the object
7771 file before and after the test and register it with ac_clean_files.

7794 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7795 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7796 the inner workings of AC_LANG_FUNC_LINK_TRY.
7797 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7798 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7799 by the function rather than ignoring it.
7800 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7801 comparing its address. Intel's interprocedural optimization was
7802 outsmarting the old heuristic. Problem reported by
7805 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7807 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7809 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7811 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7812 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7814 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7816 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7817 before removing it (chmod -R u+rwx); there are three instances of this.
7819 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7820 Stepan Kasal <kasal@ucw.cz>
7822 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7823 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7824 make its content writable before removing it. Remove an errorneous
7825 comment from the end, where the logs of the failed tests are copied
7826 to the main log file.
7828 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7830 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7831 in case the computer is too quick. Double quote the configure.ac
7834 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7835 problems if the testsuite were running too fast.
7837 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7839 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7840 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7841 (which belong to Xt, not X itself). See Debian bug 327655.
7842 * NEWS: Mention this.
7844 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7846 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7848 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7850 * config/move-if-change: Don't output "$2 is unchanged";
7851 suggested by Ben Elliston. Handle weird characters correctly.
7853 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7855 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7856 calls, so that the final expansion of this macro is shorter.
7857 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7858 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7859 the cleanup there. Use AS_VAR_* macros, to be more general.
7860 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7862 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7864 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7866 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7868 * doc/autoconf.texi (Configuration Headers): Add an index entry
7871 2005-08-26 Pavel Roskin <proski@gnu.org>
7873 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7874 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7877 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7879 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7880 The previous patch didn't work, so try a better one.
7882 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7884 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7885 in the example. Reported by Bruno Haible.
7886 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7887 "if $undefined_var;" succeeds with my shell.
7889 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7890 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7891 but change the m4_divert_text to m4_divert_once.
7893 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7895 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7896 Work around bug in Solaris /usr/xpg4/bin/awk.
7897 The bug is present in at least Solaris 8 through 10.
7899 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7901 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7902 some evil values and relying on the fact that $* concatenates the
7903 parameters by the first character from IFS.
7905 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7906 Stepan Kasal <kasal@ucw.cz>
7908 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7909 first header appears, define AH_HEADER.
7910 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7911 Update limitations about when to call AC_CONFIG_HEADERS.
7912 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7913 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7914 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7915 ``Configuration Actions''; fix their index entries.
7917 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7918 options correctly. Process N-M as M-N if M is smaller than N.
7919 Process ranges correctly so that N-N will run only N.
7920 Sort and uniquify the tests that will be run. If there is more
7921 than one test, reinsert the banners for the tests.
7922 * tests/autotest.at (Keywords): Unmark XFAIL.
7924 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7926 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7927 before passing the macro name to AH_TEMPLATE.
7929 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7930 now opens log after option processing; in particular, --version
7931 and --help do not touch config.log.
7933 * Makefile.maint: Revert the change from 2005-08-12.
7935 2005-08-22 Stepan Kasal <kasal@ucw.cz>

7941 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7943 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7944 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7947 * doc/autoconf.texi (Defining Symbols, Changed Results):
7948 Prepend to LIBS, not append, in examples.
7950 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7952 When building in place, set srcdir="."; suggested by Tim Van Holder.
7954 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7955 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7956 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7957 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7958 does not mean "no --srcdir option".
7960 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7962 * tests/autoscan.at (autoscan): New file.
7963 * tests/suite.at: Use it.
7964 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7965 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7967 * tests/autotest.at (Keywords): Test keywords combinations.
7969 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7971 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7972 add "2>&1"; gzip 1.2.4 prints help on stderr.
7974 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7976 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7977 was pushdef'ed twice while popped only once. Push it only once.
7978 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7980 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7982 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7983 prefixed by mere "===", not "configure: === ".
7985 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7987 * Makefile.maint: Update from Bison.
7989 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7990 "<tab>" in comment, so that the point is understandable.
7992 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7994 Rewrite substantial part of lib/autoconf/status.m4.
7995 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7996 and CONFIG_COMMANDS are not processed in four separate loops.
7997 Instead, there is one main loop. This alows that the common code
7998 is expanded only once, thus config.status (and configure) is smaller.
8000 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8001 the AC_LIST_FILES and cousins macros are no longer used.
8003 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8004 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8005 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8006 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8007 contain the initialization, nor the for loop, nor the associated
8008 commands; all these go to ...
8009 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8010 _AC_OUTPUT_CONFIG_STATUS.
8011 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8012 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8013 (_AC_OUTPUT_FILE): The creation of the sed script ...
8014 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8015 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8016 _AC_OUTPUT_MAIN_LOOP.
8017 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8018 _AC_CONFIG_COMMANDS): Use ...
8019 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8020 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8021 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8022 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8023 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8024 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8026 (_AC_CONFIG_UNIQUE): Update.
8027 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8028 Replaced by this ...
8029 (_AC_LIST_TAGS): ... new common macro.
8030 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8031 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8032 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8033 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8034 this didn't belong to the `config commands' section.
8035 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8036 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8037 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8038 to the `config commands' section either.
8039 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8040 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8042 ... and many changes to the comments nearby.
8044 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8045 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8046 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8047 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8048 (#define header templates): The comment at the top of the generated
8049 header now includes the name(s) of the source file(s).
8051 Several unrelated small changes:
8053 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8054 parameter to AC_DIAGNOSE.
8055 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8056 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8057 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8058 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8060 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8061 in AC_OUTPUT doesn't double-quote it either.
8062 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8065 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8067 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8068 versions of Portland Group compiler produce single- and double-quoted
8069 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8070 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8072 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8074 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8075 This is a corrected version of yesterday's patch.
8077 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8079 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8080 path, too; insert a "===" to emphasize the line.
8082 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8083 ac_cv_build_alias to ac_build_alias.
8084 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8086 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8087 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8088 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8089 (AC_ARG_VAR): ... here.
8090 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8093 Keep a list of all precious variables and process them with one simple
8094 for loop, instead of expanding all commands, or, OTOH, complicated
8095 processing of output of "set".
8096 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8097 variable names in new macro...
8098 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8099 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8100 a loop to assign all ac_env_* and ac_cv_env_* variables.
8101 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8103 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8104 its value to shell variable ac_precious_vars and call
8105 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8106 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
8107 _AC_ARG_VAR_VALIDATE.
8109 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
8110 and the AC_SUBSTs ...

8114 the ac_subst_files section in config.log.

8132 Fix my changes from 2005-07-01; reported by Noah Misch.
8133 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8134 description, the macro now accepts only a single tag.

8142 is not set, use at_top_builddir, for compatibility with older
8143 versions of autoconf.
8145 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8147 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
8148 Problem reported by Patrick Welche.
8150 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8152 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8153 sed substitution command, so that we allow | in program prefixes
8154 and program suffixes. (& is a problem anyway; we're not fixing
8156 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8157 configure_input, top_builddir, srcdir, etc.
8158 * lib/autotest/general.m4 (AT_INIT): Likewise, for
8159 PATH_SEPARATOR in AUTOTEST_PATH.

8169 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

8192 document to output the default config_* lists to config.status.
8193 Don't recognize option --file, if the functionality is not there.
8194 Likewise for --header; moreover, recognize --he and --h as shortcuts
8195 for --help in that case.
8197 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8198 matches the order of execution. No code changed.

8217 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
8219 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
8220 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8221 (AC_SUBST): Call it.
8222 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8223 the directory specific variables; but don't call it for configure_input.
8225 2005-06-28 Derek Price <derek@ximbiot.com>
8227 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8230 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8232 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

8234 due to limitations in Make syntax. Problem reported by Alexandre
8236 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

8249 from Justace Clutter.
8250 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8251 variable into diagnostic. Make the diagnostic an error, not a warning,
8252 because we really don't support spaces and suchlike in dir names.
8253 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8254 Don't worry about backslashes in srcdir; it can't happen now.
8255 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8256 Simplify ac_optarg handling.
8257 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8265 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
8267 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8268 that '\|' is not allowed in BREs; recommend using newline separated
8269 list of patterns instead of multiple -e options.
8271 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8273 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8281 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8282 b, t, r, w commands require single space, while : cannot have any.
8283 (Special Shell Variables): Fix sed code this in the example.
8284 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8285 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8287 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

8293 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8295 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8297 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8298 * doc/autoconf.texi:
8299 Don't mention Solaris versions so much, if a
8300 problem is common to all extant versions of Solaris. Say "SunOS
8301 4" instead of "SunOS" for SunOS 4.
8302 (awk): Mention more of the limitations of traditional Awk.
8303 (cat): Don't talk about cat -v.

8319 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8321 * doc/autoconf.texi: "filesystem" -> "file system".
8322 "behaviour" -> "behavior".
8323 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8324 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8326 * lib/m4sugar/m4sh.m4: Likewise.
8327 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8328 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8330 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8331 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8332 to update the man page. That way, we don't have to check in new

8343 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8345 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8346 -u, since it outputs chatter if the input files are the same.
8347 Problem reported by Ralf Menzel.
8349 2005-06-08 Derek Price <derek@ximbiot.com>
8351 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8352 renaming them since they are about to be redefined anyhow.
8354 2005-06-08 Derek Price <derek@ximbiot.com>
8356 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8357 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8358 Move m4_undefine to alphabetical order.
8360 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8362 * README: Recommend GNU M4 1.4.3 or later.
8363 * doc/autoconf.texi (Introduction): Likewise.
8364 Reword to avoid some formatting glitches.
8365 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8366 Clarify explanation of HP compiler bug.
8367 Redo example output tp match current CVS snapshot.
8368 Use @example.org in email addresses when the examples
8369 might get inadvertently cut-and-pasted into user code.
8370 Remove example of autom4te usage that doesn't seem to work now.
8371 Use modern AC_INIT (except when the example is meant to be
8372 shown with Autoconf 2.13).
8373 Update ksh info for Solaris 9 and later.
8375 Modernize description of Automake versions a bit.
8376 Don't claim a future version of Autoconf is near.

8382 follows its own advice about quoting better.
8383 Reword to avoid some formatting glitches.
8384 * doc/installt.exi: Reword to avoid some formatting glitches.
8386 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8387 Tru64 ksh pattern matching bug. Reported against Libtool by
8388 Albert Chin <libtool@mlists.thewrittenword.com> and
8389 Nicolas Joly <njoly@pasteur.fr>.
8391 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8393 m4_cdr of one-member list was [[]] (one-member list containing an
8394 empty string) instead of [] (an empty list. Callers were skewed to
8395 match this misbehaviour. As a consequence of this:
8396 - m4_foreach([x], [], [foo]) expanded to `foo', while
8397 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8398 This bug has been fixed:
8400 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8401 expand to an empty string; print error msg if called without
8403 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8404 misbehaviour; handle [] and [[]] correctly.
8406 2005-06-06 Stepan Kasal <kasal@ucw.cz>

8412 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8414 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8415 swallow records with more than 99 fields.
8416 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8417 parse the long line.
8419 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8421 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8422 swallow literals longer than 399. Reported by Ralf Wildenhues.
8423 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8424 to workaround this limitation.
8426 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8428 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8429 to gfortran, and make these the first two compiler names
8430 checked (following the general autoconf preference for gcc).

8434 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8435 (DISTCLEANFILES): Remove $(check_SCRIPTS).

8440 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8441 expression of unbounded size when processing the --list
8442 option. This runs afoul of a limit of 399 bytes per regular
8443 expression on AIX. Problem reported by Ralf Wildenhues.
8445 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

8448 * doc/autoconf.texi (Particular Headers): Reword example
8449 for multiline stdbool replacement.
8450 (Setting Output Variables): Reword text a bit. Don't
8451 give all the details about |#_!!_#|.
8452 Reword description of line replacement.
8454 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8456 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8457 now contain newlines, and substituted files must be referenced on
8458 a line alone; the sed scripts to substitute them are now very
8460 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8461 commands can be put in a sed script portably.
8462 * doc/autoconf.texi (Setting Output Variables): Document above
8463 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8464 use of multiline substitution.

8474 * tests/local.at: Don't attempt to check for negated character
8475 classes in shell scripts. The test was too brittle.
8477 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8479 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8480 * doc/autoconf.texi (Limitations of Builtins): Document this
8483 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8485 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8486 common code; used in many places in the tree.
8487 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
8488 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8490 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

8493 messages when ac_unique_file is not found.
8494 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8495 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8496 commands, for consistency with AC_MSG_ERROR and such.
8498 * bin/autoconf.as: Make more use of "shift 2" in option processing.

8511 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8512 (ac_top_builddir): ... this ...
8513 (ac_top_build_prefix): ... to this; the old name is also kept, for
8514 backward compatibility.
8515 (ac_top_builddir_sub): New variable, without the trailing slash,
8517 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

8531 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8532 argument to m4_foreach. I guess it was necessary in the past,
8533 but I think it's a no-op now.

8537 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8538 ``cat <<_ACEOF'' commands to one.

8544 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8546 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8547 the wrong patterns between ``case'' and ``esac.'' The previous
8548 code had false positives.

8616 * doc/autoconf.texi (Autoconf Language): Be more precise about
8617 quoting rules. Problems noted by Stepan Kasal.
8618 Also, throughout this document, be more careful about white space.
8619 "blank", "white space", and "space" all have different meanings
8620 and we should be careful to say what we mean.

8641 set by latest automake.
8643 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8645 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"

8659 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8660 by AC_DEFINE; it was a mistake.
8661 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8663 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8665 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8667 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8669 * doc/autoconf.texi (External Software): Quadrigraphs are not

8671 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8672 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the

8730 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8731 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8732 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8733 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8734 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8736 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8738 * NEWS: The configure command now warns you if you attempt to use
8739 a directory whose name contains a special character like space,
8741 * doc/autoconf.texi (Installation Directory Variables): Allow
8742 "," in file names. Do not use \@; it's not a portable regexp.

8754 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8755 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8756 ac_pwd, and quote srcdir.
8757 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8759 * doc/autoconf.texi: Fix some systematic formatting problems.
8760 ".)" needs a following @: if not at the end of a sentence, and
8761 similarly for "!)". "etc." should be preceded by a comma.
8762 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8764 2005-03-22 Bruno Haible <bruno@clisp.org>
8766 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8767 argument is often called 'build-aux'.
8769 2005-03-07 Stepan Kasal <kasal@ucw.cz>

8778 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8779 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8780 from a Common Lisp's `cl'.
8781 (AC_PROG_CXX): Behave according to the documentation: don't
8782 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8783 make the variable CCC precious; use `cl.exe', not `cl'.
8785 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8786 Alexandre Duret-Lutz <adl@gnu.org>
8788 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8789 /dev/null, as "configure" shouldn't read stdin, and this insulates
8790 us from problems (e.g., when testing for "cl"). Also, do this
8791 redirection before invoking "hostname" or "uname", and keep the
8792 original input stream available via...
8793 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8794 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

8806 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8807 newline if neither \c nor -n work, as that would output two
8808 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8810 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8812 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

8816 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8818 Undo previous change, except keep the change to
8819 lib/autoconf/programs.m4 that replaced grep with shell
8820 pattern-matching. This is because net-snmp configure reads stdin.
8821 Reported by Noah Misch.
8823 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8825 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8826 from /dev/null, as "configure" shouldn't read stdin, and this
8827 insulates us from problems (e.g., when testing for "cl").
8828 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8829 before invoking "hostname" or "uname".
8830 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8831 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8832 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8833 "</dev/null" since it's now done at the top of 'configure'.
8834 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8835 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8836 Also, replace grep with shell pattern-matching, to save a process.
8838 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8840 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8841 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8842 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8845 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8847 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8848 grep -q isn't portable. Improve grep -s explanation.
8849 Problem reported by Dan Manthey.
8851 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8853 * doc/autoconf.texi (Special Shell Variables): Clarify
8854 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8856 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8858 * doc/autoconf.texi: Use @acronym for DJGPP.
8859 Fix some @code's that should have been @env's, and vice versa.
8860 Sort environment variable names.
8861 Mention that shells no longer inherit IFS.
8862 Don't recommend PATH_SEPARATOR=';' so strongly.
8863 Mention that $RANDOM might expand to the empty string.
8864 "symlink" and "soft link" -> "symbolic link".
8865 Improve mktemp description (reported by Bruno Haible).

8941 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

8944 2047-byte limit on line length of portable text files.

9004 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9005 Update the long comment explaining it.
9007 m4_require no longer writes an ``is required by'' line to the
9008 execution stack. It contains only one bit of non-redundant
9009 information: that the macro was required, not called. And even
9010 this bit is useless in most situations: have you ever met a macro
9011 which both calls and requires the same macro?
9013 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9014 (_m4_defun_pro_outer): ... only via this macro, for the outermost

9017 (m4_expansion_stack_pop): Remove the misplaced comment.

9019 execution stack; slightly improve the out-of-a-defun error message.
9020 (_m4_divert_grow): New macro, counter for the temporary diversions.
9021 (_m4_require_call): Use it.
9022 * tests/m4sugar.at (m4_require): Expect output without the

9433 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9434 "char c = '\200';" rather than "char c = 0x80;" as the

9522 (Shellology, Special Shell Variables): Document that the Zsh
9523 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9524 to Alexandre Duret-Lutz for this info.

9552 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9553 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9554 (trivial change). Problem and patch reported by Andrew Church in:

9584 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9585 texinfo.tex for now (done by hand now).
9586 * Makefile.maint (wget_files, cvs_files):
9587 Remove ansi2knr.c; nobody uses it.
9588 (ansi2knr.c-url_prefix): Remove.
9589 (cvs-update): Fix test for failure. I don't know why it ever
9592 * doc/autoconf.texi: Update URLs, some of which went stale.
9593 Use @uref rather than @href.
9595 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9596 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9598 * config/config.guess, config/config.sub, config/elisp-comp,
9599 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9600 doc/fdl.texi, doc/standards.texi: Sync with master copy.

9610 Use "file name" rather than "filename" or "path",
9611 to be consistent with the terminology of the GNU coding standards.
9613 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9615 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9616 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9617 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9618 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9620 More fixes to support spaces in the name of the build directory.
9621 This isn't a complete fix but it's an improvement.
9623 * bin/autoconf.as (autom4te_options): New var.
9624 Use it instead of appending to AUTOM4TE, so that we can allow
9625 spaces in the build directory's absolute name.
9626 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9627 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9628 AT_CHECK_NOESCAPE): Likewise.
9629 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9630 main program): Likewise.

9641 and isnan. From a suggestion by Kevin Ryde.
9643 * lib/Autom4te/General.pm (END): Return correct exit status even
9644 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9646 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9648 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9649 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9650 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9652 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9654 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9655 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9656 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9657 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9658 * lib/autom4te.in (Automake-preselections): Preselect
9659 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9661 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9663 * lib/autom4te.in (Automake-preselections): Preselect
9664 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

9676 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9677 with pdksh, too. Problem reported by Patrick Welche via
9679 * doc/autoconf.texi (Shellology): Note that set -o posix is
9680 useful for pkdsh, too.
9682 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9684 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9685 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9686 Don't fail if ENV or BASH_ENV is readonly.
9687 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9688 etc. are read only. Problem reported by Ludovic Courtes.
9690 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9692 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9693 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9696 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9698 * doc/autoconf.texi (File System Conventions): Warn about
9699 names like "aux". Problem reported by Eric Blake.
9701 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9702 by zero instead of array size, so that we can use any arithmetic
9703 constant expression (instead of requiring an integer constant
9704 expression). This allows us to test expressions like DBL_MAX <
9705 LDBL_MAX, which didn't conform to the C standard using the old
9707 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9708 now that we can do floating-point tests at compile time.
9710 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9712 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9713 and LDBL_EPSILON, as the resulting expression isn't an
9714 integer constant expression and violates the C standard.
9715 Problem reported by Nelson H. F. Beebe. Also, check
9716 for "L" suffix, and check that long double doesn't have
9717 worse range or precision than double, that mixed-mode
9718 arithmetic doesn't generate a diagnostic, that double
9719 constants fit in long double.
9721 2004-06-03 Kevin Ryde <user42@zip.com.au>
9723 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9724 malloc(0) and realloc(NULL,size).
9726 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9729 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9731 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9732 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9735 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9737 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9738 can be rewritten using if-then-else. Suggested by Bruno Haible.
9740 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9742 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9743 Problem reported by Stepan Kasal.
9745 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9747 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9748 change). Patch reported by Ralf Wildenhues in
9749 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9751 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9752 function F exists if the compiler and linker let you compile an
9753 expression like (F != 0). Recent versions of GCC optimize away
9754 the reference to F in that case, since every function address must
9755 be nonzero, so the link succeeds even if F does not exist.
9756 Problem reported by Manu in
9757 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9759 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9760 "Unix". Many uses changed.
9761 (Limitations of Builtins): Explain better why the ! command isn't
9764 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9766 * lib/autom4te.in (Automake-preselections): Preselect
9767 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9769 2004-05-19 Kevin Ryde <user42@zip.com.au>
9771 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9772 referencing AC_FUNC_STRERROR_R.
9774 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9775 note pessimistic assumption when cross compiling.
9777 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9779 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9780 (until 2004) invoked subcommands with sh -e, contra POSIX.
9781 Reported by Kevin Ryde.
9783 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9785 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9786 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9787 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9788 `test -f " /usr/bin/grep"', which _always_ failed.
9789 (AC_PROG_SED): Ditto bogus PATH fix.
9790 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9791 requires that grep correctly supports _multiple_ `-e' options, rather
9792 than stating only that grep should accept `-e'.
9794 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9796 Port to C99, which requires that 'exit' be declared.
9798 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9799 to ensure that stdlib.h is included.
9800 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9801 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9802 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9803 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9804 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9805 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9806 when using 'exit' in a test; C99 requires that 'exit' be declared.
9808 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9810 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9811 now prefers 'grep' implementations that accept -e.
9812 (Limitations of Usual Tools): Describe problems of traditional
9813 egrep and fgrep with long input lines, and of traditional grep
9815 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9816 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9817 All callers changed. Append /usr/xpg4/bin to the PATH, for
9819 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9820 the user with complaints about multiple -e options.
9821 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9822 Define it with AC_PROG_GREP.
9823 * configure.ac (AC_PROG_GREP): Add.
9824 * lib/freeze.mk (GREP): New macro.
9826 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9828 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9829 a possible candidate only after all others fail, rather than
9830 consulting it first. This improves backward compatibility by
9831 better reflecting the way shell selection occurred in previous
9832 versions of Autoconf, and should help to avoid triggering latent
9833 problems in other packages, such as the one in Automake where zsh
9834 is not handled robustly:
9835 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9836 Although it is not Autoconf's responsibility to work around
9837 problems in Automake, it nevertheless makes sense to avoid
9838 introducing unnecessary incompatibilites.
9840 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9841 Gary V. Vaughan <gary@gnu.org>
9843 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9844 how deeply nested we are when a suitable tool is found, set the
9845 ac_path_TOOL_found flag.
9846 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9847 nested we are in this macro. Break out of all 3 nested loops if
9848 ac_path_TOOL_found is set.
9850 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9852 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9853 of the _AS_PATH_WALK loop too if GNU flavor is found.
9855 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9857 * doc/autoconf.texi (Limitations of Make): Update documentation
9858 for `$<'. New entry `Long lines', based on a report from Simon
9859 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9860 paragraph about DJGPP, based on a mail from Richard Dawe.
9862 2004-04-20 Paul Eggert <eggert@twinsun.com>
9864 * tests/c.at (C keywords): Don't assume that GCC supports
9865 "restrict" and "inline", as sufficiently-old GCC versions do not
9866 (also, GCC configured to be in pedantic C89 mode does not).
9867 Problem reported by Sumit Pandya in:
9868 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9870 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9871 consider -g to work if it generates warnings when plain compiles
9872 don't. Problem reported by Braden McDaniel in:
9873 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9875 * doc/autoconf.texi (Slashes): New section, to document a problem
9876 reported by Jim Meyering in:
9877 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9879 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9880 linker output files before linking, to work around IRIX 6 linker bug.
9881 Problem reported by Rainer Orth in:
9882 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9884 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9886 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9887 best tool so far counter rely on the tool path variable name to
9888 avoid checks for one tool being affected by the results of running
9889 the length check on a previous tool.
9891 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9892 match expression argument, as different greps have different
9893 regular expression flavours.
9894 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9896 (AC_PROG_EGREP): Pass 'EGREP$'.
9897 (AC_PROG_GREP): Pass 'GREP$'.
9899 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9901 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9902 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9904 2004-03-29 Paul Eggert <eggert@twinsun.com>
9906 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9907 Types, Specific Compiler Characteristics, System Services,
9908 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9909 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9910 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9911 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9913 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

9924 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9925 now defines HAVE_DECL_TZNAME if it is declared, when
9926 HAVE_STRUCT_TM_TM_ZONE is not defined.
9927 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9928 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

9937 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9939 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9940 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9941 H. F. Beebe for the bug report.
9943 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9945 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9946 quoted -cmdline argument in Portland Group compiler (bug
9947 reported by Jeffrey J. Barteet).
9949 2004-03-25 Kevin Ryde <user42@zip.com.au>

9986 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9987 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9988 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a

9991 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9992 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9995 2004-03-03 Paul Eggert <eggert@twinsun.com>
9997 * bin/Makefile.am (edit): Don't use $< in a context where
9998 POSIX doesn't require support for it. Use $@.in instead.
9999 Problem reported by Anthony N. Frasso in
10000 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
10001 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
10003 2004-02-23 Gary V. Vaughan <gary@gnu.org>
10005 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
10006 from the next generation of Libtool.
10007 * lib/autom4te.in (Autoreconf-preselections): Ditto.
10009 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10011 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
10012 is not always thread-safe. Report from Nathanael Nerode.
10014 2004-02-18 Paul Eggert <eggert@twinsun.com>
10016 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10017 problem on QNX reported by Stephen Rasku in
10018 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
10020 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10021 $(m4sh_m4f_dependencies); this removes a FIXME.
10022 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10023 (MAINTAINERCLEANFILES): Split into pieces,
10024 one per related section. Add $(srcdir)/wrapper.in.
10026 2004-02-09 Paul Eggert <eggert@twinsun.com>
10028 * doc/autoconf.texi (Setting Output Variables): Emphasize that
10029 AC_SUBST provides no portable way to escape literal newlines.
10031 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10032 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10033 Darwin uses -lcrt2.o and there's little point to cataloging all
10034 the system variants. Partial fix reported by Andreas Waechter in:

10049 refer to the correct file.
10050 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
10051 the behavior of the third argument.
10052 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
10053 correctly the behavior of the third argument. Document
10054 what the three macros that AU_DEFUN defines do. Fix
10055 warning message when the third argument includes $0

10059 Eric Sunshine <sunshine@sunshineco.com>
10060 Paul Eggert <eggert@twinsun.com>
10062 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
10063 (AS_INIT): Output shell initialization there. Removed optional
10064 parameter. Expand _AS_SHELL_FN_SPY.
10065 (AS_INIT_WITH_SHELL_FN): Removed.
10066 (_AS_SHELL_FN_SPY): New macro.
10067 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

10073 (_AS_RUN): Move it here, support testing with eval.
10074 (AS_REQUIRE_SHELL_FN): Require shell functions when
10076 (_AS_LINENO_WORKS): Put around braces, we do not
10077 trigger the bash bug anymore.
10078 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10079 use AS_INIT_WITH_SHELL_FN.
10080 * bin/autoconf.in, tests/wrapper.in: Regenerated.
10082 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

10088 (AU_DEFUN): Honor the third parameter, create autoupdate
10089 macros with AU_DEFINE.
10090 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
10091 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

10101 that the macro is not present anymore in the updated

10110 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
10111 2003 (except 1997) to the list of copyright years. This undoes
10112 the 2003-05-22 change, which removed the older years from the list.
10113 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

10119 grep or ggrep program in PATH that accepts as long lines as
10121 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
10123 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
10124 egrep and fgrep respectively if $GREP -E/-F don't work.
10125 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10126 _AC_PROG_GREP, and AC_PROG_SED.
10127 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10128 longest input length accepted by a command.
10129 (AC_PROG_SED): Use it.

10133 2004-01-27 Paul Eggert <eggert@twinsun.com>

10157 2004-01-26 Paul Eggert <eggert@twinsun.com>
10159 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10160 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10161 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10162 not <inttypes.h>. Problem reported by Tim Mooney in
10163 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10164 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10167 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10168 otherwise "make check" fails because it forbids cmp (I guess
10169 because cmp treats files as binary on DOS-like systems).
10171 * tests/mktests.sh: Update copyright date to 2004, since some tests
10172 have changed in 2004.
10174 2004-01-23 Gary V. Vaughan <gary@gnu.org>

10177 non-truncating sed or gsed program in PATH.
10178 * tests/acprograms.at: Add it.
10179 * doc/autoconf.texi (Particular Programs): Document it.
10182 2004-01-15 Paul Eggert <eggert@twinsun.com>
10184 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10185 -std1 disables some useful extensions on Tru64. Problem reported
10186 by N. Lichtmaier in
10187 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10189 2004-01-14 Paul Eggert <eggert@twinsun.com>
10191 * doc/autoconf.texi (Programming in M4sh): Document that
10192 AS_MKDIR_P succeeds if the destination is a symbolic link
10193 to an existing directory.
10194 (Limitations of Usual Tools): Note that mkdir -p might not
10195 succeed on symlinks to directories.
10197 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10199 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10200 * bin/autoheader.in: Grammar fix in message.
10201 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10202 Test for dir before calling mkdir -p. (trivial changes)
10204 2004-01-13 Eric Blake <ebb9@byu.net>
10206 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10207 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10209 2004-01-10 Jim Meyering <jim@meyering.net>
10211 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10213 2004-01-09 Paul Eggert <eggert@twinsun.com>
10215 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10216 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10217 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10218 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10219 AC_COMPILE_IFELSE, since we now assume our caller invokes
10220 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10221 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10222 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10223 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10225 2004-01-07 Paul Eggert <eggert@twinsun.com>
10227 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10228 `"'...'"`, as it's confusing (and I suspect it may not work on
10229 some platforms). The code was incorrect anyway, as it assumed
10230 that \$ evaluated to itself in that context. Reported by
10231 Alexandre Duret-Lutz.
10233 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10235 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10236 and _LT_AC_TAGCONFIG.

10240 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10241 example, and add more examples. Reported by Eric Sunshine.

10259 by doing lineno substitution only on lines containing "$LINENO".
10261 2004-01-04 Paul Eggert <eggert@twinsun.com>
10263 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10264 Use "rm -f" to remove conftest.sed, not plain "rm".
10265 Bug reported by David Relson in
10266 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10268 * Makefile.am (autom4te-update):
10269 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10270 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10271 * doc/autoconf.texi (Guidelines): Likewise.

10285 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10286 -c -o might not work. From a suggestion by Kevin Ryde.
10287 (C Compiler, Generating Sources, Limitations
10288 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10289 Don't put '-o' after non-options, as POSIX doesn't allow this.
10290 Mention that cc's name might be gcc or c89 or whatever.
10292 2004-01-04 Kevin Ryde <user42@zip.com.au>
10294 * doc/autoconf.texi: Add various further index entries.
10296 2003-12-29 Paul Eggert <eggert@twinsun.com>
10298 * bin/autoreconf.in (autoreconf_current_directory):
10299 Fix typo: mkdir without umask arg.
10301 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10303 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10304 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10305 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10306 explanation clearer.

10310 * doc/autoconf.texi (Default Includes): Fix misspelling of

10317 * tests/atlocal.in: Store the result here.
10318 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

10320 of explicitly testing.
10321 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10322 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10323 * tests/tools.at (Syntax of the shell scripts): Simplify
10324 using AT_CHECK_SHELL_SYNTAX.

10326 AT_CHECK_PERL_SYNTAX.

10393 parameter of AU_DEFUN.
10394 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

10396 Use AC_DEFUN directly, not AU_DEFINE.
10397 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
10398 the expanded body, consistently with other macros such as AC_USG.
10400 2003-11-17 Paul Eggert <eggert@twinsun.com>
10402 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
10403 into the initial confdefs.h, to work around a bug in NextStep 3.3
10404 patch 3 reported by Eric Sunshine.
10406 2003-11-15 Kevin Ryde <user42@zip.com.au>
10408 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10409 than $target since the latter is not usual, add guidelines on when to

10591 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10592 -mGLOB_options_string stuff for Intel ifc, which can cause

10616 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10617 cache variable instead of $G77 to decide whether to include -O2,
10618 since $G77 is specific to Fortran 77.

10622 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10623 free" flag. Re-order flags tested into rough order of popularity.
10625 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10627 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10628 arguments so that it can be used with syntax identical to
10629 AC_PROG_F77, and so that we can more easily decide to
10630 remove/deprecate the DIALECT optional argument in the future if it
10631 proves troublesome.
10632 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10633 non-freeform-supporting compilers. Document freeform flags.
10635 2003-10-03 Akim Demaille <akim@epita.fr>

10697 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10698 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10699 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

10704 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10705 directory for AC_CONFIG_COMMANDS' first argument exists.
10706 This makes valid the invocation of _AC_SRCPATH that follows.
10707 Reported by Eric Sunshine.

10731 The test suite are sometimes assigning timings incorrectly.
10732 Reported by Henk Krus.
10733 Diagnosed by Nicolas Joly.
10735 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10737 Instead of making AT_help a sequence of assignments to grow
10738 $at_help_all, just make AT_help_all be the growing contents of
10739 $at_help_all, and make a single assignment in...
10741 (at_times_skip): Flip the meaning and rename as...
10742 (at_times_p): this.
10743 (AT_INIT): When summarizing the test that ran, remove

10753 (ifnames): chmod -w.
10754 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10755 executables, not bin/ executables! Otherwise all the magic needed
10756 to find non installed files is turned off. This caused a failure
10757 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10758 as found in its environment (sent by tests/autoreconf): pointing
10759 to bin/autom4te that could not find its files.
10760 * tests/mktests.sh: Force the replacement of generated files, for
10761 the sake of "mv" program that are interactive when overwriting a

10856 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10858 Add support for newer Fortran dialects. The F77 interface is
10859 unchanged, and continues to support Fortran 77. New FC macros
10860 correspond to all the old F77 macros, with output variables FC,
10861 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10862 available dialect, but older dialects can be specified. There are
10863 new macros AC_FC_SRCEXT to set the source extension, and
10864 AC_FC_FREEFORM to accept free-form source files.

10901 * tests/local.at: Require 2.57.
10902 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10903 are defaulted by AT_CHECK anyway.
10904 Use AT_CHECK_AUTOM4TE.
10905 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10908 2003-08-27 Akim Demaille <akim@epita.fr>
10910 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10911 when -Wobsolete is set.
10912 Set it on by default.
10913 Suggested by Klee Dienes.
10915 2003-08-27 Akim Demaille <akim@epita.fr>

10949 * Makefile.cfg (local-checks-to-skip): New.
10950 * Makefile.maint (local-check): Rename as...
10951 (local-checks-available): this.
10952 (local-check): New.
10954 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
10955 * configure.ac: Require Automake 1.7.6.
10957 2003-08-22 Akim Demaille <akim@epita.fr>
10959 Output stack traces in warnings.
10961 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10962 Replace the former...
10963 (m4_warn): Pass the call stack to _m4_warn.
10964 * bin/autom4te.in: Adjust to output the call stack.
10965 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10967 2003-08-22 Akim Demaille <akim@epita.fr>
10969 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
10970 * bin/autom4te.in: Adjust.
10972 2003-08-21 Akim Demaille <akim@epita.fr>
10974 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10975 (&verbose): Remove.
10976 (&getopt): Adjust the note and verb channels, depending upon
10978 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10979 * bin/autoupdate.in: Adjust.
10980 Use &verb, not &verbose.
10982 2003-08-21 Akim Demaille <akim@epita.fr>
10984 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10986 ($help): Use Autom4te::ChannelDefs::usage.
10987 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10988 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10990 2003-08-21 Akim Demaille <akim@epita.fr>
10992 First stab at preserving warnings between calls to autom4te,
10993 including when the cache is used.
10995 There are still several issues: (i) there are too many runs of m4
10996 (one for include, one for warnings, and some more), (ii) warnings
10997 spreading on several lines are not handled gracefully, (iii) the
10998 code meant to have the call stack display for errors does not work
10999 (its handling should move from m4 to autom4te).
11001 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11003 (@preselect): Add m4_warn.
11004 ($exit_status): Remove, use $exit_code.
11005 ($help): Use Autom4te::ChannelDefs::usage.
11006 (&handle_m4): No longer define the m4_warnings.
11007 At each run, extract and report the warnings.
11008 Always cache the result, including if the exit status is on
11009 failure, since if nothing changes, we should result in the same
11010 failure, hence we can use the cache.
11011 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11012 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11014 (m4_warn): Redefine as a do-nothing: it is its invocation that
11015 matters, as warnings are now reported via traces.
11016 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11017 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11018 the latter reveals calls to the former.
11022 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
11024 2003-08-21 Akim Demaille <akim@epita.fr>

11034 (&parse_warnings): Accept a list of warning requests.
11035 (&usage): Return a string, not a side effect.
11036 (cross): New warning category.
11038 2003-08-21 Akim Demaille <akim@epita.fr>
11040 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
11041 (&require_configure_ac): Accept an optional directory argument.
11042 ($configure_ac): Remove.
11043 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
11044 (&catfile): Remove.
11045 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
11046 * bin/autoscan.in: Adjust.
11048 2003-08-20 Akim Demaille <akim@epita.fr>
11050 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
11051 Reported by Alexandre Duret-Lutz.
11053 2003-08-20 Akim Demaille <akim@epita.fr>
11055 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11056 * bin/autom4te: Adjust.
11057 In particular, be Autoconf tools are really silent when properly
11058 working, bind the verbosity of the 'note' channel to $verbose.
11059 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11060 (&xsystem, &contents): Remove, since they are exported by...
11061 * lib/Autom4te/FileUtils.pm: this.
11063 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
11064 * lib/Autom4te/FileUtils.pm: here.
11066 2003-08-20 Akim Demaille <akim@epita.fr>
11068 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
11069 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
11072 2003-08-20 Akim Demaille <akim@epita.fr>
11074 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
11075 (autom4te-update): New.
11076 * Makefile.cfg (update): Bind autom4te-update.
11078 2003-08-19 Derek Price <derek@ximbiot.com>
11080 * lib/autotest/general.m4: Comment various HELP_* diversions.
11081 (PARSE_ARGS_BEGIN): New section for option parsing related
11083 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define

11121 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
11122 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
11123 shorter column three. Add DESCRIPTION to log file content.
11125 2003-08-13 Derek Price <derek@ximbiot.com>
11127 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
11130 2003-08-12 Derek Price <derek@ximbiot.com>
11132 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
11133 (AT_CHECK_NOESCAPE): Move core functionality to...
11134 (_AT_CHECK): ...this new macro.
11136 2003-08-07 Derek Price <derek@ximbiot.com>
11138 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
11139 (AT_CHECK_NOESCAPE): ...to this new macro.
11141 2003-07-31 Paul Eggert <eggert@twinsun.com>
11143 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
11144 in Bash 2.01. Problem reported by Brian Gough in
11145 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

11149 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
11150 -lcrt1.o, for OS X. (trivial change)
11152 2003-07-07 Paul Eggert <eggert@twinsun.com>
11154 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
11155 inside '#ifndef __cplusplus'. Problem reported by
11158 2003-07-06 Bill Clarke <llib@computer.org>
11160 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
11161 'long', not 'int', for benefit of Sun's recent C++ compilers
11162 (trivial change). See:

11171 From Paolo Bonzini.
11172 * lib/autom4te.in (args): Add local.at? for Autotest args.
11173 This change was made on autom4te.cfg which is generated.

11181 2003-06-23 Akim Demaille <akim@epita.fr>
11183 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11184 not all of them. This fixes 1. the fact that when testing
11185 Autoconf there are many many config.log, 2. the incorrect use of
11186 top_srcdir to find config.log.
11187 Don't mix the detailed output of failed test with the summary of
11188 failures. Rather, append detailed log afterwards.
11190 2003-06-23 Akim Demaille <akim@epita.fr>
11192 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11193 always run: output config.log on $at_group_log.
11195 2003-06-23 Akim Demaille <akim@epita.fr>
11197 * tests/torture.at (#define header templates): Don't use quotes in

11213 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
11214 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
11215 ensuring we add -std1 for full-ANSI.
11217 * doc/autoconf.texi (hdrindex): New macro.
11218 Add index entries for portability of various standard header files.

11247 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
11248 (TEST_SCRIPT): New diversion.
11249 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
11250 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11251 (AT_INIT): Support for expected failures.

11258 Autoconf nor Automake.
11259 (&contents): New, from Automake.
11262 2003-05-28 Paul Eggert <eggert@twinsun.com>

11265 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11266 is the inverse of localtime.

11270 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11271 (handle_exec_errors): New function. Work around $! being
11272 altered by WEXITSTATUS.
11273 (xqx, xsystem): Use handle_exec_errors.
11275 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11277 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11278 Do not call `_exit()', simply modify `$?'.
11279 (xsystem): Reset $! before running system, and check it afterward.
11280 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11281 63 for version mismatches.
11283 2003-05-23 Akim Demaille <akim@epita.fr>
11285 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11286 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11287 the middle of a line).

11291 2003-05-23 Akim Demaille <akim@epita.fr>
11293 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

11295 difference with a plain failure.

11305 Paul Eggert <eggert@twinsun.com>
11307 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11308 Remove `#include <stdlib.h>' from the list; we should never
11309 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11310 resulting namespace pollution would cause other tests to fail.
11311 Configure scripts run with some older versions of g++ and HP's
11312 aCC would fail due to such an #include. Problems reported by
11313 Matthew Mueller in <http://bugs.debian.org/120704> and by
11315 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11316 In the test, use the test declaration before including <stdlib.h>,
11317 as that's closer to how it'll be used.
11319 2003-05-23 Akim Demaille <akim@epita.fr>
11321 * doc/autoconf.texi (Header Portability): ucred.h.
11324 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11326 Overhaul Autotest's logging: generate separate log files
11327 in testsuite.dir/NNN/testsuite.log, and append them to
11328 testsuite.log instead of re-running the test verbosely.
11330 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11331 file descriptor, write 0 to at_status_file instead of setting
11332 at_status=0, initialize some new variables (at_status_file,
11333 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11334 to rerun the tests, instead append the at_group_log to the
11335 at_suite_log when a test fails.
11336 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11337 with the AS_MESSAGE_LOG_FD redirected to stdout.
11338 (AT_CLEANUP): save the output status in $at_status_file
11339 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11340 its original place.
11341 (AT_CHECK): since tests are run with a redirected stdout,
11342 and used to be re-run in verbose mode, turn some $at_verbose
11343 into echo, and don't redirect the output of testing stdout
11346 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11347 the name of the debugging directory and information about

11467 2003-05-06 Akim Demaille <akim@epita.fr>
11469 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11470 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11471 by aclocal.m4 is changed it might require the importing of another
11472 m4 extension file, i.e., aclocal must be run.
11474 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11475 (&parse_args): Use --force with aclocal if required and supported.

11489 2003-04-29 Derek Price <derek@ximbiot.com>
11491 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11492 seperator with m4_append_uniq(). It doesn't work.
11493 (AT_CLEANUP): Add `;' to end of at_help_all.

11575 * tests/torture.at (Configuring subdirectories): Require aclocal
11576 1.4, otherwise the test fails, as it does support configure.ac.

11665 * bin/ifnames.in: Add final newline to help and version messages.
11667 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
11668 to cope with DOS-style absolute paths, when constructing
11671 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11672 When constructing paths with IFS=:, quote the path. If we're
11673 constructing a DOS-style absolute path, we don't want to split it
11676 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11679 2003-02-25 Pavel Roskin <proski@gnu.org>

11691 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,

11696 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11697 format starting with "-".
11699 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11701 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11702 is not portable inside Makefile.
11704 2003-02-20 Akim Demaille <akim@epita.fr>
11706 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11707 compiler says yeah, but preproc says nope, compiler is right.
11708 Conversely, prompt the reader to send a bug report to the
11709 maintainers of the package, not of Autoconf.
11711 2003-02-20 Klee Dienes <kdienes@apple.com>
11713 * bin/autoreconf.in (autoreconf_current_directory): Properly
11714 handle an empty aclocal.m4.

11719 $ac_prefix_program.
11722 2002-12-23 Paul Eggert <eggert@twinsun.com>
11724 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11725 innocuous variant befor including <limits.h> or <assert.h>. This
11726 works around a bug reported by Albert Chin: HP-UX 11i
11727 (and earlier versions) have a <limits.h> that declares
11728 gettimeofday and many other functions.
11730 2002-12-03 Paul Eggert <eggert@twinsun.com>
11734 * NEWS, configure.ac: Update version.
11736 * doc/fdl.texi: Upgrade to FDL version 1.2.
11738 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11739 nontrivially in main's body, so that f's external declaration is
11740 not optimized away in AIX. This should fix the bug reported by
11742 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11744 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11745 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11746 defined, to support freestanding compilers. This should fix the
11747 bug reported by Momchil Velkov in
11748 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11750 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11751 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11762 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11763 \(.*\) match is too long and there is something more to be checked.
11764 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

11782 Update from masters.
11784 2002-11-14 Akim Demaille <akim@epita.fr>
11786 * Makefile.maint: Sync with Bison, i.e.:
11787 (po-check): Scan .l and .y files instead of the
11788 .c and the .h files that they generate. This fixes the bug
11789 reported by Tim Van Holder in:
11790 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11791 Look for N_ as well as for _. Try to avoid matching #define for
11795 2002-11-14 Akim Demaille <akim@epita.fr>
11797 * doc/autoconf.texi (C Compiler): Compiling several files at once.
11798 From Paul Eggert and Albert Chin-A-Young.
11800 2002-11-14 Akim Demaille <akim@epita.fr>
11802 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11803 From Paul Eggert and Albert Chin-A-Young.
11805 2002-11-14 Kevin Ryde <user42@zip.com.au>
11807 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11808 than assigning in main, to avoid HP cc +O3 optimizing it away.
11810 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11812 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11813 option. Process --recheck after parsing all options. Pass -q
11814 option to configure on --recheck.
11815 (AC_OUTPUT): Pass -q from configure to config.status.
11816 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11817 arguments to record.
11818 * doc/autoconf.texi (config.status Invocation): Document
11819 config.status -q option.
11821 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11823 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11824 Makefile.in if Makefile.am exists.
11825 (output): Strip `.am' from Makefiles. Don't
11826 output AC_CONFIG_FILES if no Makefiles were found.
11828 2002-11-07 Akim Demaille <akim@epita.fr>
11830 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
11831 (local_updates): New.
11832 * Makefile.maint: Update, from CVS Bison.
11833 (local_updates): New.
11835 2002-11-06 Akim Demaille <akim@epita.fr>
11837 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11838 declaration in extern "C" too.
11839 Reported by Roberto Bagnara.
11841 2002-11-06 Akim Demaille <akim@epita.fr>
11843 * tests/torture.at (Configuring subdirectories): Don't use grep
11845 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
11846 Reported by Ezra Peisach.
11848 2002-11-05 Akim Demaille <akim@epita.fr>
11850 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11852 We _have_ to stop using the old compatibility scheme that tried to
11853 avoid useless backslashes because Libtool 1.4.3 contains a
11854 AC_DEFINE([error_t], [int],
11855 [Define to a type to use for \`error_t' if it is not
11856 otherwise available.])
11857 We _have_ to quote the single quote and backslashes with \. The
11858 old compatibility scheme saw that ` was backslashed, and therefore
11859 did not quote the single quote. Hence before this patch, Autoconf
11860 was not compatible with Libtool.
11862 2002-11-04 Paul Eggert <eggert@twinsun.com>
11864 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11869 2002-11-04 Akim Demaille <akim@epita.fr>
11873 * Makefile.maint (update, cvs-update, po-update, do-po-update):
11875 * config/texinfo.tex: Update.
11877 2002-11-03 Akim Demaille <akim@epita.fr>
11879 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
11881 (&autoreconf): here.
11882 ($help, $make, &parse_args, &autoreconf_current_directory):
11884 * doc/autoconf.texi (autoreconf Invocation): Adjust.

12251 Reported by Alexandre Duret-Lutz.
12253 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12258 (&up_to_date): If a file that was included according to the cache

12273 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12274 if some file was changed instead of `print'.
12275 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

12309 file name to enable parallel executions.
12310 From Sam Varshavchik.
12312 2002-10-08 Akim Demaille <akim@epita.fr>
12314 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12315 aclocal invocation, as Gettext macros might not be visible to
12317 Instead of blindly running autopoint, scan configure.ac (not the
12318 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12319 Reported by Paul D. Smith.
12321 2002-10-08 Paul Eggert <eggert@twinsun.com>
12323 Work around problems found when POSIXLY_CORRECT=1 is set.
12324 None of this seems to have anything to do with POSIX, really,
12325 but it's how Perl getopt works.
12326 * bin/autom4te.in (parse_args): Configure GetOpt with
12328 * doc/autoconf.texi (Invoking autom4te):
12329 --warning -> --warnings.

12351 * tests/torture.at (Configuring subdirectories): Be robust to
12352 users who use config.site to require for a cache: in this case,
12353 the two last configure runs, using two different sets of
12354 arguments, trigger a legitimate error.

12389 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12390 (.m4.m4f): Don't pass --prepend-include, since that's done by
12391 tests/autom4te itself.
12392 * lib/autoscan/Makefile.am: Include freeze.mk.
12393 (autoscan.list): New target --this file is no longer a source.
12394 (autoscan.pre): New file.
12396 2002-09-28 Akim Demaille <akim@epita.fr>
12398 * bin/autoscan.in (@kinds): Make them singular.
12400 (&init_tables): When --debug, report the list of rules to ease
12401 tracking changes in autoscan.list.
12402 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12404 2002-09-28 Akim Demaille <akim@epita.fr>

12412 2002-09-28 Akim Demaille <akim@epita.fr>
12414 * lib/autoscan/functions, lib/autoscan/headers,
12415 * lib/autoscan/identifiers, lib/autoscan/makevars,
12416 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12417 `functions' line is now prefixed with `function:'.
12418 * bin/autoscan.in (&init_tables): Adjust.
12420 2002-09-28 Akim Demaille <akim@epita.fr>
12422 From now on, autoscan files must always map a macro name to a
12423 word: there is no `default' macro for autoscan.
12425 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12427 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12430 2002-09-28 Akim Demaille <akim@epita.fr>
12432 * bin/autoscan.in (%c_keywords): Remove.
12433 (&used): Keep only track of the words we might be interested in.
12434 (&output_kind): It is no longer needed to look for non active

12448 Thanks to Bill Moseley and Paul Eggert.
12449 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12450 the tmpdir must be created.
12451 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12452 dir be in the build tree, instead of $TMPDIR.

12456 * bin/autoscan.in: Improve the comments.
12457 (&parse_args): Drop obsolete undocumented options.

12465 Reported by Ralf Corsepius.
12466 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12468 2002-09-26 Akim Demaille <akim@epita.fr>
12470 Single suffix rules and seperated dependencies are not portable.
12472 * doc/autoconf.texi (Installation Directory Variables): Update.
12473 (Limitations of Make): Some about `Single Suffix Rules and
12474 Separated Dependencies'.
12475 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12476 (ifnames, autoscan, autom4te): Un-factor into several rules.
12478 2002-09-25 Paul Eggert <eggert@twinsun.com>
12480 * BUGS (Interoperability bugs): New section. Mention libtool
12481 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12483 2002-09-24 Paul Eggert <eggert@twinsun.com>
12485 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12486 make handles suffix-rules differently from GNU make.
12488 * bin/Makefile.am (SUFFIXES, .in): Remove.
12489 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12490 Move the body of the old .in rule here.
12492 2002-09-16 Akim Demaille <akim@epita.fr>
12494 i960 compilers create `b.out' files by default.
12495 Reported by Ralf Corsepius.
12497 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12498 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12500 2002-09-13 Paul Eggert <eggert@twinsun.com>
12502 * doc/autoconf.texi (Particular Headers): Remove obsolete
12503 reference to `struct timezone' in the description of

12511 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12512 * Makefile.am: Adjust.
12514 2002-09-13 Akim Demaille <akim@epita.fr>
12516 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12517 reading config.log when the compiler is rejected.
12518 Suggested by Guido Draheim.
12520 2002-09-13 Akim Demaille <akim@epita.fr>
12522 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12523 (chdir_init) might hang when stat'ing mounted directories.
12524 Reported by Vance Shipley.
12526 2002-09-12 Akim Demaille <akim@epita.fr>
12528 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12531 2002-09-12 Akim Demaille <akim@epita.fr>
12533 * doc/autoconf.texi (Defining Symbols): Present two different
12534 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12535 difference between 1 argument calls, and 2-3 argument calls.
12537 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12539 * doc/autoconf.texi: Review grammar and punctuation.
12541 2002-09-11 Paul Eggert <eggert@twinsun.com>
12543 * doc/autoconf.texi: Fix minor formatting, spelling, and
12545 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12546 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12549 2002-09-11 Akim Demaille <akim@epita.fr>
12551 * doc/autoconf.texi (Questions): Rename as...
12553 (Defining Directories): New.
12555 2002-09-09 Akim Demaille <akim@epita.fr>
12557 * doc/autoconf.texi (Making testsuite Scripts): Update.
12558 Suggested by Nishio Futoshi.
12560 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12562 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12563 plain `@' is wanted.
12565 2002-09-09 Akim Demaille <akim@epita.fr>
12567 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12568 `duplicates', since the algorithm was too naive and could keep
12569 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12570 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12571 Reported by Ralf Corsepius.
12572 * tests/torture.at (Configuring subdirectories): Exercise these
12575 2002-09-09 Akim Demaille <akim@epita.fr>
12577 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12578 looking for a replacement file.
12579 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12580 directory is relative.
12581 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12582 directory definition.
12583 Reported by Andreas Schwab and Jim Meyering.
12585 2002-09-06 Akim Demaille <akim@epita.fr>
12587 * doc/autoconf.texi (Setting Output Variables): Clarify what
12588 precious variables are.
12589 Suggested by Pontus Skoeld.
12591 2002-09-05 Akim Demaille <akim@epita.fr>
12593 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12594 (ifnames, autoscan, autom4te): Since we don't only depend on
12595 configure.ac variables (such as VERSION etc.), but also on prefix
12596 and so forth, depend on Makefile, not configure.ac.
12597 Reported by Alexandre Duret-Lutz.
12598 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12600 2002-09-05 Kevin Ryde <user42@zip.com.au>
12602 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12603 doesn't seem to be confined to ia64, just say "some versions".
12605 2002-09-04 Akim Demaille <akim@epita.fr>
12607 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12609 * Makefile.am (maintainer-clean-local): Remove.
12610 (MAINTAINERCLEANFILES): Remove COPYING.
12612 2002-09-03 Paul Eggert <eggert@twinsun.com>
12614 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12615 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12618 2002-09-03 Akim Demaille <akim@epita.fr>
12620 * configure.ac: Bump to 2.53d.
12621 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12622 as of today, on Automake's team suggestion.
12624 2002-09-03 Akim Demaille <akim@epita.fr>
12628 2002-09-02 Akim Demaille <akim@epita.fr>
12630 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12632 * configure.ac: Disable SITE_MACRO_DIR.
12634 2002-09-02 Jim Meyering <meyering@lucent.com>
12636 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12637 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12638 Also, tweak grammar: s/make sure to/be sure to/.
12640 2002-09-02 Paul Eggert <eggert@twinsun.com>
12642 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12643 directory names are generally preferable to physical names.
12645 2002-09-02 Akim Demaille <akim@epita.fr>
12647 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12648 Reported by Raja R. Harinath.
12649 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12650 * bin/autoupdate.in: Use error instead of die.
12652 2002-09-01 Paul Eggert <eggert@twinsun.com>
12654 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12655 ordinary shell concatenation rather than echo+tr+sed command that
12656 runs afoul of a long-line-related sed bug in Solaris 8.
12658 * bin/autoheader.in (parse_args): --warning -> --warnings.
12660 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12661 stdout, as traditional "ls" does.
12662 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12663 _AC_COMPILER_EXEEXT_O): Likewise.
12664 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12666 * bin/autoconf.as: Add --prepend-include option. This patch was
12667 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12668 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12670 * bin/autoconf.in, configure: Regenerate.
12672 * doc/autoconf.texi (Special Shell Variables): Mention
12673 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12675 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12676 MAILPATH and set PS1, PS2, PS4 to default values, to work
12677 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12678 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12679 the Autoconf documentation specifies; fall back to "unset" only if
12680 this fails. Use a shell for-loop for this rather than an m4 loop,
12681 to shorten the output script.
12683 2002-08-30 Paul Eggert <eggert@twinsun.com>
12685 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12686 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12687 for the CDPATH problem. Document PWD.
12688 (Limitations of Builtins): Document the problem that "cd $foo" and
12689 "ls $foo" may refer to different directories in shells conforming
12690 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12691 example, since the old example is now out of date.
12693 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12694 FOO" and "ls FOO" talk about different directories; this catches
12695 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12698 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12699 of rolling our own unset.
12700 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12701 in practice we needn't worry about CDPATH if unset doesn't work.
12703 * Makefile.in, aclocal.m4, bin/Makefile.in,
12704 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12705 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12706 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12707 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12708 tests/Makefile.in: Regenerate with Automake 1.6.3.
12710 * config/config.guess, config/config.sub, config/mkinstalldirs:
12713 * configure: Regenerate with self.
12715 2002-08-30 Kevin Ryde <user42@zip.com.au>
12717 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12720 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12722 * bin/autom4te.in (Request::load): Correctly test for "do" read
12725 2002-08-29 Akim Demaille <akim@epita.fr>
12727 * lib/Autom4te/General.pm (&xqx): New.
12728 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12729 hand, which is not portable.
12731 * bin/autom4te.in: Use them.
12732 Use &error instead of die.
12733 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12736 2002-08-17 Paul Eggert <eggert@twinsun.com>
12738 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12739 default list of compilers to try, since it was long ago superseded
12740 by the ksh fc builtin. Suggested by Steven G. Johnson.
12742 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12744 * doc/autoconf.texi (Invoking autom4te): End the option table,
12745 fixing a bug introduced by the previous patch.
12746 (Limitations of Make): Add a 'target lookup' subentry in the
12747 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12749 2002-07-29 Mark D. Roth <roth@feep.net>
12751 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12752 options and use $AUTOM4TE_PATH.
12753 * doc/autoconf.texi: Remove documentation of autom4te
12754 --include-envvar and --site-macro-subdir options and document
12755 use of $AUTOM4TE_PATH.
12756 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12757 arguments from each language section.
12759 2002-07-29 Paul Eggert <eggert@twinsun.com>
12761 * doc/install.texi: Include copyright symbol in copyright notice.
12763 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12765 (AM_MAKEINFOFLAGS): New macro.
12766 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12767 * Makefile.am (INSTALL): Use the new macros.
12768 Use -o rather than --output, since "missing" does not grok --output.
12770 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12772 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12773 comments do not always work. Never trust the exit status of
12776 2002-07-24 Kevin Ryde <user42@zip.com.au>
12778 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12779 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12781 2002-07-23 Paul Eggert <eggert@twinsun.com>
12783 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12784 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12785 apparently treats PATH="nonexistent" as if it contained ".".
12786 Bug reported by Stefan `Sec' Zehl.
12788 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12790 * doc/autoconf.texi (Limitations of Make): Mention the special
12791 handling of the obj/ directory by BSD make.
12793 2002-07-20 Kevin Ryde <user42@zip.com.au>

12833 description of the tarname default.
12835 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
12837 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12838 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12839 latter was not run.
12841 2002-07-17 Akim Demaille <akim@epita.fr>
12843 * lib/Autom4te/General.pm (find_file): Browse the directories in
12844 the order they are given.

12852 2002-07-17 Mark D. Roth <roth@feep.net>
12854 * configure.ac: Add --enable-site-macro-dir option.

12856 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
12857 --site-macro-subdir options.
12858 * bin/autoconf.in: Add --prepend-include option.
12859 * bin/autoheader.in: Add --prepend-include option.

13056 This improves on an earlier suggestion by H. Peter Anvin.
13058 2002-05-16 Paul Eggert <eggert@twinsun.com>
13060 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13061 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13062 Both macros now accept an optional source-dir arg.
13063 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13065 * NEWS: Document this.
13066 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13068 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13069 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13070 not for GNU extensions; this undoes part of the 2000-11-03 change,
13071 reverting to 2.13-compatible behavior.

13079 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13080 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13081 and it causes a 'test' syntax error if it fails.
13082 Bug reported by Stephen Gildea.
13084 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13085 If prototypes are supported, use them to check this at compile-time,
13086 instead of trying to check it at run-time. If we must do a run-time
13087 check, assume that setvbuf is standard when cross-compiling, as
13088 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13089 Bug reported by Paul D. Smith.
13091 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13092 argument specifying location of getloadavg.c. This removes a
13093 FIXME. This idea was taken from Jim Meyering's implementation in
13095 * doc/autoconf.texi (Particular Functions): Document this.
13096 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13097 that's what the code does; this fixes a bug reported by

13102 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13103 autopoint instead of gettextize.
13104 ($uses_alocal): Rename as...
13105 ($uses_aclocal): this.
13106 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13107 Suggested by Bruno Haible.

13111 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13113 2002-04-29 Paul Eggert <eggert@twinsun.com>
13115 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13116 files to be 1 second older; just set them to be the same time.
13117 Also, sleep 1 second after the first aclocal, to work around
13118 problems with sub-second time stamps on the input files.
13120 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13122 * doc/autoconf.texi: Mention "set -e -x" lossage

13129 From Christian Cornelssen.
13131 2002-04-29 Akim Demaille <akim@epita.fr>
13133 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13134 of lack of $LINENO support, then the test will compare the $LINENO
13135 in testsuite vs. the lineno in the test file. This is wrong, of
13137 Be sure to protect it.
13138 Reported by Patrick Welche.
13140 2002-04-25 Akim Demaille <akim@epita.fr>
13142 * doc/autoconf.texi (Obsolete Macros): Typo.
13143 Reported by Vladimir Volovich.
13145 2002-04-25 Akim Demaille <akim@epita.fr>
13147 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13148 than some of the input files, hence, on the second run of aclocal,
13149 if some of its input are younger, make them older.
13150 Suggested by Paul Eggert.
13152 2002-04-25 Akim Demaille <akim@epita.fr>
13154 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

13163 (_AC_INIT_PREPARE): Use them to log them.
13164 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13165 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13166 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13167 _AC_SUBST_FILES and _AC_SUBST_VARS.
13168 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13170 2002-04-24 Akim Demaille <akim@epita.fr>
13172 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13173 autoheader, so that automake does not complain about a missing
13174 config.h.in that was to be created.
13176 2002-04-23 Akim Demaille <akim@epita.fr>

13362 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
13363 (_AC_COMPILER_OBJEXT): Use them.
13364 Fixes Debian #138666.
13366 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13368 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13370 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13371 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13372 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13373 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13374 (AC_C_CONST): Same.

13388 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,

13405 2002-03-25 Paul Eggert <eggert@twinsun.com>
13407 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13408 as POSIX requires, as it doesn't work with Zsh.
13409 * doc/autoconf.texi (Assignments): Document the problem.
13411 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

13414 about VPATH, overriding of macros in sub-makes, and handling of

13419 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13420 problem with here-document buffer boundaries.
13422 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13423 when reinvoking the shell, to work around problems with installers
13424 who put strange things like "cd" commands in their environments.

13449 (Limitations of Usual Tools): Add mkdir section.
13451 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13452 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13453 back on AS_DIRNAME to compute prefixes otherwise; this is
13454 roughly what mkinstalldirs does. That way, we need not have
13455 our own filename disassembler. The old disassembler did not
13456 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13458 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13459 Create at_test_all by a series of assignments,
13460 not by a single assignment of a long string. The latter causes ksh
13461 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13462 presumably because of a buffer overrun.
13464 2002-03-14 Paul Eggert <eggert@twinsun.com>
13466 * lib/autotest/general.m4 (at_times_skip):
13467 Renamed from at_times. Now a boolean.
13468 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13469 says 'times: not found'.
13471 2002-03-14 Akim Demaille <akim@epita.fr>
13473 * bin/autoreconf.in (&study_gettextize): New.
13474 (&autoreconf): Handle newest gettextize.

13498 2002-03-11 Andreas Schwab <schwab@suse.de>

13512 2002-03-08 Akim Demaille <akim@epita.fr>
13514 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13516 2002-03-08 Akim Demaille <akim@epita.fr>
13518 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13519 aliases the actual variables, and modifications of the former
13522 2002-03-08 Akim Demaille <akim@epita.fr>
13524 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13525 because of C-c: have m4 output in tmp files, then mv them.
13527 2002-03-08 Akim Demaille <akim@epita.fr>

13548 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13549 * lib/autoconf/general.m4 (AC_INIT): More informative error
13550 message for LIBOBJ.
13552 2002-03-04 Akim Demaille <akim@epita.fr>

13557 2002-03-04 Akim Demaille <akim@epita.fr>
13559 * doc/autoconf.texi (Transforming Names): Equality between target
13560 and host is irrelevant.
13561 (Specifying Names, Canonicalizing): Remove all references to the
13562 backward compatibility hooks. Rather, collect them all into...
13563 (Hosts and Cross-Compilation): this new section.
13564 * doc/install.texi (System Type): Ditto.
13565 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13566 that `--host' implies cross-compilation.
13568 2002-03-04 Akim Demaille <akim@epita.fr>
13570 * doc/autoconf.texi (Evaluation Macros): New.
13571 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13573 (_m4_foreach): Define the variant with immediate evaluation so
13574 that it contains exactly the items, not an expression which
13575 evaluation is the current item.
13576 (m4_re_string, m4_re_word): Don't over quote them.
13578 2002-03-04 Akim Demaille <akim@epita.fr>
13580 Instead of having stacking `shift's evaluated at the end, let
13581 `foreach' loops immediately evaluate them.
13583 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13584 $*. This is the n-th time I change my mind, but hopefully this is
13587 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13589 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13590 it was only a hack for m4_text_wrap.
13591 (m4_car2): Remove, replaced by...
13593 (_m4_foreach): Adjust.
13594 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13595 m4_bpatsubst for clarification.

13686 2002-02-05 Akim Demaille <akim@epita.fr>
13688 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13712 Also, pass `--reload-state=' on them, so...
13713 (handle_m4): don't.

13753 2002-01-28 Akim Demaille <akim@epita.fr>
13755 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13756 AUTOTEST_PATH *after* it was set.
13757 Don't put `.' in the PATH: the user should be precise and `./' if
13758 needed. In addition, given that the test suite does some `cd', if
13759 `.' is in the path, the `tested programs' sections will report
13760 programs found in the test suite's directory, while during the
13761 tests (performed in their own directory), these programs are no
13762 longer visible. In other words, the results is confusing and

13839 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13840 and PACKAGE_BUGREPORT from here...
13841 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the

13870 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13871 trailing files, don't apply `-rf' to files which might not be
13872 created by configure (core, core.*, and *.core), but just `rm -f'.
13873 Suggested by Jonathan Kamens.
13875 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13877 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13879 2001-12-14 Akim Demaille <akim@epita.fr>
13881 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13883 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13885 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13886 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13887 abs_srcdir, top_srcpath to abs_top_srcdir.
13888 (_AC_OUTPUT_FILES): Adjust.
13889 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13890 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13891 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13893 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13895 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13896 C/Fortran linking on HP/UX, by extracting the Fortran library
13897 search path from the LPATH line in the $F77 -v output.
13899 2001-12-12 Kevin Ryde <user42@zip.com.au>
13901 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13902 forbidden file descriptors table.
13904 2001-11-26 Akim Demaille <akim@epita.fr>
13906 * bin/autoscan.in (%c_keywords): Build it at top level.
13907 Map to 1 in order to simplify its uses.
13909 2001-11-26 Akim Demaille <akim@epita.fr>
13911 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13912 Remove $filepath, useless.
13913 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13914 variables, they are really part of the tokens.
13915 Split the input line on spaces and then look for tokens.
13916 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13917 because of `lex$U.$(OBJEXT)'.
13918 (&scan_files): Use "@list" instead of join.
13919 * doc/Makefile.am (CLEANFILES): Add *.fns.
13921 2001-11-26 Akim Demaille <akim@epita.fr>
13923 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13924 Remove, replaced by...
13925 * tests/wrappl.in: Be common for all the Perl executables.
13926 In particular autoscan and autoheader want -I.
13927 * configure.ac: Adjust.
13928 * lib/autoscan/headers: errno.h is portable.
13930 2001-11-26 Akim Demaille <akim@epita.fr>
13932 * bin/autoscan.in (used): New.
13935 2001-11-26 Akim Demaille <akim@epita.fr>
13937 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13939 (&scan_sh_file): Remove a duplicate pattern.
13940 (&check_configure_ac): Use long options.
13941 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13943 2001-11-26 Akim Demaille <akim@epita.fr>
13945 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13946 Before, having a line containing the opening of a multi line
13947 comment made the whole line be ignored.
13949 2001-11-26 Akim Demaille <akim@epita.fr>
13951 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13952 (testsuite Scripts): Be one of its subsection.
13953 (Autotest Logs): New.
13955 2001-11-26 Akim Demaille <akim@epita.fr>
13957 Test groups are now run two directories deeper.
13959 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13960 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13962 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13963 top_srcdir, builddir and top_builddir.
13964 Use `at_*dir' relatively to the directory containing the
13965 suite, use `*dir' when relatively to the current group dir.
13967 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13969 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13970 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13971 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13974 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13976 * doc/autoconf.texi (Using System Type): Add an example of `case
13977 $host' usage so people quit using `case $target' everywhere.
13979 2001-11-22 Akim Demaille <akim@epita.fr>
13981 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13982 spotted by Jim Meyering.
13984 2001-11-16 Paul Eggert <eggert@twinsun.com>
13986 This patch implements a `long double' suggestion by Oliver Kiddle.
13988 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13989 static, to catch errors if the value isn't known at compile-time
13990 and the compiler supports dynamic arrays. Change its name from
13991 `_array_' to `test_array' to avoid potential name clashes.
13992 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13993 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13994 better than double. Catch a bug in GCC 2.95.2 x86.
13995 * doc/autoconf.texi (C Compiler): Document the above.
13998 2001-11-13 Akim Demaille <akim@epita.fr>
14000 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14002 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14004 2001-11-13 Akim Demaille <akim@epita.fr>
14006 * lib/autotest/general.m4 (AT_INIT): After having run the test
14007 group, go back to the initial directory, not to at_suite_dir.
14009 2001-11-13 Akim Demaille <akim@epita.fr>
14011 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14012 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14013 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14015 (AT_CHECK_CONFIGURE): Use absolute paths.
14016 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14017 The problem is still the old one: there is no means in M4 (that I
14018 know about) to create a defining macro, because there is no means
14019 to create `$1' etc., therefore, the defining macro ``swallows''
14020 all the arguments meant to the defined macro.
14022 2001-11-13 Akim Demaille <akim@epita.fr>
14024 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14025 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14027 * tests/aclocal.m4: Remove, as it is no longer used.
14029 2001-11-13 Akim Demaille <akim@epita.fr>
14031 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14032 variable names when referring to a single test group, or to
14033 `suite' when referring to the whole test suite.
14034 `at_last_test' is removed: m4 compute at_format itself.
14035 (at_stdout, at_stder1, at_stderr): New variables.
14036 (AT_CHECK): Use them.
14038 2001-11-13 Akim Demaille <akim@epita.fr>
14040 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14042 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14043 Do it as soon as a test fails, don't wait till the end of the test
14045 Don't remove $as_me.[0-9]*, since these files no longer exist.
14047 2001-11-13 Akim Demaille <akim@epita.fr>
14049 * tests/tools.at: Use absolute paths, since we are no longer run
14052 2001-11-13 Akim Demaille <akim@epita.fr>
14054 Now that tests are running in their own private dir, there is no
14055 need to list the files to remove at the end of tests groups.
14057 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14058 (AT_data_files, at_data_files): Remove.
14059 (AT_CLEANUP, AT_DATA): Simplify.
14061 Remove the group dir if !debug && !failed.
14062 * tests/atspecific.m4: Adjust.
14064 2001-11-13 Akim Demaille <akim@epita.fr>
14066 Start a new layout for Autotest: `testsuite' creates
14067 `testsuite.dir' in which the at-check-line etc. files are to be
14068 found, and `testsuite.dir/003' where the test group 3 is run.
14070 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14071 at_check_line_file, at_format, at_test_normalized, at_group_dir
14073 Create the directories.
14074 Use absolute paths for at- files.
14075 (AT_CHECK): Adjust.
14077 2001-11-11 Michael Matz <matz@kde.org>
14079 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14081 (m4_car): Properly quote arguments.
14083 2001-11-13 Akim Demaille <akim@epita.fr>
14085 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14086 with stricter rules on LIBOBJS.
14088 2001-11-12 Paul Eggert <eggert@twinsun.com>
14090 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14091 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14094 2001-11-12 Akim Demaille <akim@epita.fr>
14096 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14098 2001-11-12 Akim Demaille <akim@epita.fr>
14100 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14101 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14102 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14103 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14104 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14105 specify to what the macro should be defined (typically to 1).
14107 2001-11-12 Akim Demaille <akim@epita.fr>
14109 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14112 2001-11-12 Akim Demaille <akim@epita.fr>
14114 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14115 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14116 definition used by Automake where LEX is +/- "${missing} lex" and
14117 `missing' itself contains variables.
14119 2001-11-12 Akim Demaille <akim@epita.fr>
14121 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14122 Now that M4sh pushes BODY, the comments were output at the end of
14125 2001-11-08 Akim Demaille <akim@epita.fr>
14127 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14128 that we can trace macros from aclocal.m4.
14129 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14130 obsoleted, and redirect to the former anyway.
14131 Reported by Ralf Corsepius.
14133 2001-11-08 Akim Demaille <akim@epita.fr>
14135 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14136 processed only if present.
14137 * tests/torture.at (Configuring subdirectories): Use autoreconf
14138 instead of successive calls to autoconf.
14139 Add a nonexistent subdirectory to exercise the patch above.
14140 Reported by Ralf Corsepius.
14142 2001-11-08 Kevin Ryde <user42@zip.com.au>
14144 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14145 doesn't accept .S files.
14147 2001-11-07 Akim Demaille <akim@epita.fr>
14149 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14150 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14151 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14152 * bin/autom4te.in (warn_forbidden): New.
14153 (handle_output): Use it.
14154 Read m4_pattern_forbid with messages.
14156 2001-11-05 Akim Demaille <akim@epita.fr>
14158 * bin/autom4te.in (--normalize): Remove.
14159 * lib/autom4te.in: Adjust.
14161 2001-11-05 Akim Demaille <akim@epita.fr>
14163 * tests/Makefile.am (testsuite): Rename this target as...
14164 ($(TESTSUITE)): this.
14167 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14169 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14170 the --prefix option, also remove it's argument.
14172 2001-11-05 Akim Demaille <akim@epita.fr>
14174 * doc/autoconf.texi (testsuite Invocation): Update.
14175 (Writing testsuite.at): Update.
14177 2001-11-03 Akim Demaille <akim@epita.fr>
14179 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14181 2001-11-03 Akim Demaille <akim@epita.fr>
14183 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14184 (&file_name_is_absolute): New, wrappers around routines from
14186 Use and export them.
14187 (&find_configure_ac): Optionally take a directory where to look at.
14188 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14190 Default @ARGV to `.', not find_configure_ac.
14191 (&autoreconf): Argument is a directory.
14192 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14193 * doc/autoconf.texi (autoreconf Invocation): Update.
14195 2001-11-03 Akim Demaille <akim@epita.fr>
14197 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14198 (@export_forward_subs): New.
14199 Add basename, dirname, and fileparse.
14201 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14202 Don't look for aclocal flags if we already know aclocal is not
14204 Move aclocal.m4t only if it exists.
14205 Reported by Ezra Peisach.
14207 2001-11-03 Akim Demaille <akim@epita.fr>
14209 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14210 passed on command line, defaulting to ./configure.ac if present.
14211 (&maybe_autoreconf, File::Find): Remove, unused.
14212 (&autoreconf): If autoconf is not used, don't try to trace.
14214 2001-11-02 Akim Demaille <akim@epita.fr>
14216 * configure.ac: Bump to 2.52g.
14218 2001-11-02 Akim Demaille <akim@epita.fr>
14222 2001-11-02 Akim Demaille <akim@epita.fr>
14224 * config/config.guess, config/config.sub, doc/standards.texi:
14225 * config/lispdir.m4: Update from masters.
14226 * configure.ac: Bump to 2.52f.
14228 2001-11-02 Akim Demaille <akim@epita.fr>
14230 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14231 Don't run aclocal when aclocal.m4 is not from aclocal.
14233 Don't run libtoolize and gettextize if --install is not given.
14235 2001-11-01 Paul Eggert <eggert@twinsun.com>
14237 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14238 be invoked before _AS_LINENO_PREPARE.
14239 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14240 than character ranges.
14242 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14243 invoking AS_BASENAME. Set the locale variables to 'C' if
14244 possible, as POSIX requires this to get the traditional
14246 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14248 2001-10-31 Paul Eggert <eggert@twinsun.com>
14250 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14251 with {}, as that triggers a bug in Bash 2.05.
14253 (_AS_LINENO_PREPARE): Use Sed rather than
14254 Awk. Fix the sed prepass to work even if there are multiple
14255 instances of $LINENO on the same line. Do not substitute for
14256 other variables like $LINENOT. Do not check file dates; such a
14257 check is unreliable on sufficiently fast machines, and removing
14258 the check makes the code simpler and more reliable. Check for
14259 output and chmod failures.
14261 * doc/autoconf.texi (Special Shell Variables): Document
14264 2001-10-31 Akim Demaille <akim@epita.fr>
14266 * tests/Makefile.am (atconfig): Remove this target, Automake
14269 2001-10-31 Akim Demaille <akim@epita.fr>
14271 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14272 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14273 provided, while it is optional.
14274 * configure.ac: Adjust.
14276 2001-10-26 Paul Eggert <eggert@twinsun.com>
14278 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14279 lib/Autom4te/Struct.pm:
14280 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14283 * doc/autoconf.texi (Special Shell Variables): Document some
14284 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14286 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14287 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14288 eval $LINENO is not portable in practice.
14290 2001-10-24 Akim Demaille <akim@epita.fr>
14292 * lib/Autom4te/General.pm (backname): New.
14294 2001-10-24 Akim Demaille <akim@epita.fr>
14296 * m4/: Remove, merged into...
14299 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14301 * doc/autoconf.texi (Shellology): Mention the problems with bash
14302 2.05's use of ANSI quoting in its `set' builtin.
14304 2001-10-22 Paul Eggert <eggert@twinsun.com>
14306 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14307 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14308 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14309 POSIX decided to standardize on the int flavor of strerror_r.
14310 Always do char* test, as there's no reason not to.
14311 Assign to a char* var, to catch strerror_r that returns int*.
14313 * doc/autoconf.texi (Particular Functions):
14314 Document the above changes. Also, document the fact that
14315 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14317 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14319 2001-10-20 Akim Demaille <akim@epita.fr>
14321 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14322 the executable was missing from the log.
14324 2001-10-20 Akim Demaille <akim@epita.fr>
14326 * lib/Autom4te/General.pm (&update_file): If destination is
14327 unchanged, remove the source.
14328 (&up_to_date_p): Don't be verbose, be debug.
14329 * bin/autoreconf.in: No longer support --m4dir.
14330 (&autoreconf): Display the full path of the configure.ac we are
14332 Trace it only once.
14333 Be sure to honor --force with gettextize.
14334 Always run aclocal.
14335 * doc/autoconf.texi: Adjust.
14337 2001-10-20 Akim Demaille <akim@epita.fr>
14339 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14341 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14342 `intl' is already present, as it refuses unless --force.
14343 (&parse_args): Use -I, --include instead of the old Autoconf
14345 ($localdir, $autoconf_dir): Remove.
14347 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14349 2001-10-19 Jens Petersen <petersen@redhat.com>
14351 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
14352 * doc/autoconf.texi (Particular Programs): Likewise.
14354 2001-10-19 Akim Demaille <akim@epita.fr>
14356 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
14357 file in @configure_input@.

14822 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14824 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14825 * bin/autoupdate.in: Ditto.
14826 * bin/autoheader.in: Reworded a few comments.
14827 * bin/autoconf.in: Reworded help text for a few options.
14828 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,

14831 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14833 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14834 already have $file). Set output files to binary mode (helps avoid
14835 CR issues on DOSish systems).
14837 2001-09-19 Akim Demaille <akim@epita.fr>
14839 * lib/autotest/general.m4: Englishoes.
14840 From Tim Van Holder and Alexey Mahotkin.
14842 2001-09-18 Paul Eggert <eggert@twinsun.com>
14844 * doc/autoconf.texi (Common Shell Constructs): New node,
14845 documenting AS_DIRNAME.
14846 (Limitations of Usual Tools): Refer to it when discussing dirname.
14847 Also, update discussion of POSIX standard to reflect latest draft.
14849 * lib/autoconf/c.m4:
14850 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14852 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14853 Do not pass a first argument with leading '-'
14854 to expr, by parenthesizing initial integers that might be negative.
14856 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14857 now merely checks whether it is an error to pass an argument
14860 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14861 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14862 whether it is a (compile-time) error to pass an argument to
14863 getpgrp. This simpler test supports the revised documentation,
14864 and is all that AC_FUNC_GETPGRP's users really need.
14866 2001-09-18 Akim Demaille <akim@epita.fr>
14868 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14876 2001-09-18 Paul Wagland <paul@wagland.net>
14878 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14880 Add test for AS_BASENAME.
14881 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14882 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14883 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14884 * tests/base.at: Fixed the expected responses. The old ones were
14886 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14887 the documentation claims it should (and how it behaved in 2.13).
14889 2001-09-18 Akim Demaille <akim@epita.fr>
14891 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14892 the AC_CONFIG_COMMANDS invocation.
14893 This also solves the name clash problems.
14894 Don't set the package's ID.
14895 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14896 No longer to be shipped.
14897 (version.in): Remove.
14898 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14899 * lib/autoconf/status.m4: Adjust.
14900 Use `m4_PACKAGE_STRING'.
14901 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14902 the only optional argument is the name of the test suite.
14903 Expect `package.m4' to define the package signature.
14904 * lib/autom4te.in (Autotest): Add `package.m4?'.
14905 * tests/Makefile.am (package.m4): New.
14906 * tests/suite.at: ifnames is a victim.
14908 2001-09-18 Akim Demaille <akim@epita.fr>
14910 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14911 AC_LIBSOURCE, AC_CONFIG_FILES.
14912 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14913 program version string doesn't match the package's.
14914 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14917 2001-09-17 Paul Eggert <eggert@twinsun.com>
14919 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14920 Allow expression to return any value that can fit into unsigned long
14921 (not int, as before). Check for output errors.
14923 2001-09-17 Bruno Haible <haible@ilog.fr>
14925 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14926 Always include <stdio.h> and <stdlib.h>. Evaluate
14927 the expression in an extra function before these includes. Call
14928 fprintf "%d" only after ensuring the argument is of type 'int'.
14929 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14931 2001-09-17 Paul Eggert <eggert@twinsun.com>
14933 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14934 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14935 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14936 when they don't exist.
14938 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14939 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14942 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14943 version with the version used by fileutils 4.1, except use
14944 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14947 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14949 2001-09-13 Akim Demaille <akim@epita.fr>

14989 * lib/autotest/general.m4 (AT_INIT): Create and remove
14990 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14991 test suites can cohabit.
14993 2001-09-13 Akim Demaille <akim@epita.fr>
14995 * tests/mktests.sh: Don't output banners for empty test files.

15047 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

15050 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

15094 to avoid GCC warnings.
15097 2001-09-05 Akim Demaille <akim@epita.fr>
15099 * bin/autom4te.in: --language is -l, not -s.
15101 2001-09-05 Akim Demaille <akim@epita.fr>
15103 Be ready to handle filenames as stupid as `dnl.at', for if even
15104 the maintainer is dumb enough to do that...
15106 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15107 excellence in M4 quotation: consider `__file__' is active.
15109 And BTW, when invoking m4, pass the --include in the right order:

15186 to m4sugar was lacking!
15188 2001-08-31 Akim Demaille <akim@epita.fr>
15190 * man/Makefile.am (.x.1): We really have to pass
15191 autom4te_perllibdir.

15195 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

15202 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
15203 Use directly autom4te, not autoconf.

15261 There is no such envvar since the inception of autom4te.cfg.

15283 * lib/Autom4te/General.pm (&find_peer): Remove.
15284 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15285 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15286 * man/Makefile.am: Let help2man rely on PATH instead of trying to

15786 2001-08-15 Akim Demaille <akim@epita.fr>
15788 * bin/autom4te.in (@m4_warning): New.
15789 (&handle_m4): Use it.
15790 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

15869 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15870 magic values from an object file when cross-compiling.
15871 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15873 2001-08-10 Akim Demaille <akim@epita.fr>
15875 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15877 Suggested by Russ Allbery.
15879 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15881 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15882 current $prefix to the sub-configures.
15884 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15886 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15887 extension (needed on BeOS). Reported by Guido van Rossum.
15889 2001-08-09 Akim Demaille <akim@epita.fr>
15891 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15893 2001-08-07 Akim Demaille <akim@epita.fr>
15895 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15897 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15898 No need to remove the files before and after the each test, before
15899 each test and at the end of the suite is enough.
15900 Display only the children `times', not the shell's.
15901 If the test failed or was skipped, at-times is not available.
15903 2001-08-07 Akim Demaille <akim@epita.fr>
15905 Always produce testsuite.log, including when there are no
15906 failures. This helps getting information on skipped tests, and
15907 duration of the tests. Err, implement the latter btw.
15909 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15910 Dump information on the first run of each test.
15911 (AT_CLEANUP): Create `at-times' containing the duration of the
15914 2001-08-07 Akim Demaille <akim@epita.fr>
15916 The use of `dumpstat' revealed that `len' was used although it
15917 should not. m4_text_wrap was using it, but in the Autoconf world
15918 where it is legal. Hence (i) test M4sh in its own world, not
15919 Autoconf's, and (ii), ahem, fix the bug :)
15921 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15922 does not like `' instead of [].
15923 (AT_INIT): Forbid `^_?AT_'.
15924 And don't output such tokens.
15925 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15926 `script.as', and `autom4te.cache'.
15927 Remove `empty' and `macro' which are no longer used.
15928 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15929 * tests/m4sugar.at: Use it.
15930 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15932 2001-08-07 Akim Demaille <akim@epita.fr>
15934 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15936 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15938 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15940 2001-08-04 Akim Demaille <akim@epita.fr>
15942 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15943 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15945 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15946 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15947 (AC_F77_MAIN): Likewise.
15949 2001-08-04 Akim Demaille <akim@epita.fr>
15951 Don't rely on M4sugar outputting the patterns in files, since we
15952 might process the output _without_ running m4, hence without these
15955 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15956 * bin/autom4te.in (@Request::includes): Remove, unused.
15957 (@Request::source): Rename as...
15958 (@Request::input): this.
15959 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15960 (&handle_output): Fetch the patterns from the traces.
15961 `$forbidden' and `$allowed' are constant: use m//o.
15962 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15963 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15965 2001-08-04 Akim Demaille <akim@epita.fr>
15967 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15968 autoconf', i.e., in addition to caching traces, cache the output.
15970 * bin/autom4te.in (Request::cache): Rename as...
15971 (Request::id): this.
15972 ($cache, $icache, $tcache, $ocache): New.
15973 (&handle_m4): Save M4 output in the cache instead of $tmp.
15974 (&handle_output): Adjust.
15975 (&up_to_date_p): Check that the output cache is up to date too.
15976 (top level): Run `&handle_m4' iff force or the cache is invalid.
15977 Run `&handle_output' if the output cache is more recent.
15979 2001-08-04 Akim Demaille <akim@epita.fr>
15981 * bin/autom4te.in ($force): New.
15982 (&parse_args, &print_usage): -f, --force is a new option.
15983 (&handle_output): CPP directives might have spaces after `#'.
15984 (&parse_args): The first file only can be frozen.
15986 2001-08-04 Akim Demaille <akim@epita.fr>
15988 Don't let autom4te compute the `include' traces several times:
15989 first check that the trace cache file is up to date, and then
15990 compare its timestamp with that of the output.
15992 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15993 the preamble. Don't require 5.005 as Autom4te::General does it,
15994 and better yet (use `use', not `require'!).
15995 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15996 Class::Struct as Autom4te::Struct.
15997 * lib/Autom4te/General.pm (File::stat): Use it.
15998 (&mtime): New, export it.
15999 * bin/autom4te.in: Use it.
16000 Declare `$req' is invalid if it is outdated.
16001 Don't declare it valid before saving it if something went wrong.
16003 2001-08-04 Akim Demaille <akim@epita.fr>

16006 must be proposed to the users.
16008 * bin/autom4te.in (@required_trace): Remove.
16010 (&parse_args, &print_usage): -p, --preselect is a new option.
16011 (&up_to_date_p): Adjust.

16016 * tests/tools.at (autoconf --trace: user macros): Check traces on
16017 macros invoked without arguments, and macros invoked with multiple
16020 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

16025 2001-08-03 Akim Demaille <akim@epita.fr>
16027 * bin/autoconf.in ($@): Work around the usual sh bug.
16030 2001-08-03 Akim Demaille <akim@epita.fr>
16032 Clean up the handling of the M4 builtins tracing exception.
16034 * bin/autom4te.in (Request::request): Don't complete M4 builtins

16037 (@m4_builtin): this.
16038 (%m4_builtin_alternate_name): New.
16039 (&parse_args): Complete the trace requests with alternate names.

16045 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
16046 m4_if, and m4_wrap.
16048 2001-08-03 Akim Demaille <akim@epita.fr>
16050 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
16051 (m4_divert_pop): Dump the whole diversion stack when a diversion
16053 * bin/autom4te.in (&handle_output): Remember of the first
16054 occurrence of a possibly undefined macro, not the last.
16055 Complain about the possibly undefined macros in the same order as
16056 the appear in the output.
16057 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16058 * tests/tools.at (autoconf: forbidden tokens, basic)
16059 (autoconf: forbidden tokens, exceptions): No longer sort
16060 autoconf's stderr, as it is now deterministic.
16061 Check that `dnl' is caught.
16063 2001-08-01 Akim Demaille <akim@epita.fr>
16065 * configure.ac: Bump to 2.52c.

16082 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
16083 `END', as `Autom4te::General::END' will be triggered.
16084 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
16085 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
16086 system to run `mv', `rm', and `cmp'.

16090 * lib/Autom4te/General.pm (&unique): New.
