1677 Cover more potentially problemtic file names. Use the new
1680 Properly handle funny file names for headers in config.status.
1681 The test suite did not cover this bug because the code was not
1682 quoting properly the arguments of `rm -f' (which "fails" silently)
1683 as well as the arguments of `diff' (whose output was redirected to
1684 /dev/null so we couldn't see its error message).

1802 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1804 <DEFAULTS>: Delay computation of variables based on $at_dir...
1805 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1806 <TESTS>: Re-invoke via absolute name, since -C may be in effect.

1830 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1831 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1832 mode, we change to the source directory, also set $ac_pwd so we

1834 * tests/torture.at (Deep Package): Extend test to contain two
1835 config subdirs on the top level.

1889 (m4_require): Use m4_do, not m4_join.
1891 Fix some whitespace tests on cygwin.
1892 * tests/tools.at (autom4te and whitespace in file names): Restore

1896 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1898 Optimize AC_REQUIRE.

1911 * tests/base.at (Input/Output): Likewise.
1912 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1913 config.guess, and config.sub to test source tree.

1929 * tests/m4sh.at (LINENO): Quote $0.
1931 Fix testsuite program wrapper for whitespace in `pwd`.
1932 The problem here is that the usual mantra is that command
1933 variables can contain arguments, thus we cannot just escape
1934 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1935 $top_builddir/tests directory early in $PATH, so that the
1936 wrappers are found by their plain name.
1937 * tests/wrapper.as: Put $testdir early in $PATH.

1950 <at_func_create_debugging_script, Driver Loop>:
1951 Quote $at_group_dir.
1952 * tests/autotest.at (whitespace in absolute testdir): New test.
1954 * lib/autom4te.in: Quote @datadir@.
1956 Proper file name escaping in Autoconf programs and Perl modules.
1957 This includes escaping of characters special to the shell
1958 as well as special to Perl, e.g., leading `<' or `>'.
1959 For example, when $file starts with `>', `open ">$file"'
1960 wrongly tries to append to a different file.
1961 * bin/autoconf.as: Fix quoting for autom4te options.
1962 * lib/Autom4te/General.pm (shell_quote): New function, taken
1963 from coreutils, written by Jim Meyering.

1967 * bin/autoreconf.in (parse_args): Likewise.
1968 * bin/autoscan.in (main): Likewise.
1969 * bin/autoupdate.in (main): Likewise.
1970 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1971 * bin/ifnames.in: Likewise, XFile usage fixes.
1972 * tests/tools.at (autom4te and whitespace in file names): Extend
1973 test. Test twice, with special characters allowed on w32, and the
1974 rest. Test leading and trailing whitespace, for `open_quote'.
1975 (autotools and whitespace in file names): New, analogous test.
1976 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1977 by Russ Allbery and Eric Blake.
1980 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1981 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1982 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1983 (update_file, contents): Use it.
1985 * Makefile.am (autom4te-update): Rewrite for git.
1987 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1989 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1991 Fix copyright years.
1992 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1993 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

2005 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2007 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2008 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2009 #undef as this runs afoul of our new way of creating config.h.
2010 Problem reported by Jim Meyering in
2011 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2013 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2015 Fix autom4te for unusual characters in input file names.
2016 * bin/autom4te.in (files_to_options): Quote active characters
2018 * tests/tools.at (autom4te and white space in file names):
2021 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:

2024 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2026 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2027 `#AT_STOP_...' line at the end of each test.
2029 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2031 * lib/autotest/general.m4 (AT_INIT): For awk line number
2032 extraction script, ensure `$at_group' has a defined value
2033 even for the empty set, and properly quote its usage inside
2036 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2038 * doc/autoconf.texi (Shell Functions): New chapter. Document
2039 IRIX sh $0 issue in functions, move content from ...
2040 (Portable Shell): ... here.
2041 (Shell Script Compiler): Note that shell functions are not
2042 totally unportable any more.
2044 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2045 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2047 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2048 extracting the line numbers of the last needed test.
2050 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2052 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2055 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2057 Fix IRIX testsuite debugging failures: $0 in functions.
2058 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2059 Do not use $0 inside a function, as IRIX sh will set that to the
2060 function name rather than the script invocation name.
2062 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2063 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2065 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2066 to extract test scripts.
2067 (AT_INIT): Extract and cache test script line numbers.
2069 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2071 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2072 subsequent fixups; the awk -> here-document conversion trashes
2073 performance too much with AIX sh.
2075 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2077 * tests/local.at: Do not test m4, perl with AT_TESTED.
2079 Diagnose and guard against write errors dealing with config.status.
2080 The general idea is this: all write failures from `configure'
2081 writing `config.status' are indicated by $ac_write_error, which
2082 is only checked at the end. This is safe because config.status
2083 code is not executed before the file is complete. Other write
2084 failures, be they inside config.status, or in sub shell/awk
2085 scripts spawned from configure or config.status, typically need
2086 earlier checking, as their results are used right afterwards.
2087 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2088 before writing config.status, check afterwards.
2089 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2090 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2091 Set `ac_write_error' for write failures to config.status. Barf
2092 upon write failures to temporary files.
2093 Adjust note about closing and reopening the here-document.
2094 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2095 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2096 reopening the here-document.
2097 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2098 Ensure `ac_write_error' does not escape into config.status.
2099 Also, add a couple of code paths not yet exercised in the test
2100 suite: a config file with input from stdin, and a config header
2102 Suggestion for catching write errors by Bruno Haible.
2104 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2106 Avoid error with Tru64 awk and testsuite lines with many words.
2107 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2108 reads the testsuite, set the field separator to an unusual value,
2109 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2110 even splits the input if $i, i>0, was never accessed in the script.
2112 Revert 2007-10-17 change.
2113 * TODO: Multiline args in config files and headers mean something
2114 different and are not fixed, see
2115 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2116 Report by Stepan Kasal.
2118 * doc/autoconf.texi (Generic Programs): Fix typo.
2120 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2122 AC_*_TOOL does not canonicalize the prefix
2123 * doc/autoconf.texi (Generic Programs): Do not say that
2124 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2126 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2128 Diagnose write errors in config.status instantiations.
2129 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2130 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2132 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2133 Extend test to also check for some write error failures, using...
2134 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2135 Report by Bruno Haible.
2138 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2140 (_AT_CHECK): Use less indentation, to save space.
2142 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2144 Add witness macro for @top_build_prefix@ substitution.
2145 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2146 (_AC_OUTPUT_FILE): Mention it here.
2148 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2149 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2151 * lib/autotest/general.m4 (at_func_test): Remove.
2152 (AT_INIT): Pre-extract test groups into separate files.
2153 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2154 Remove at-test-source files together with the $at_group_dir.
2155 * tests/autotest.at (Long test source lines): New test.
2157 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2159 Shell functions and variables may share a namespace.
2160 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2163 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2165 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2168 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2170 * lib/autoconf/status.m4: Fix a couple of comment typos.
2172 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2174 2007-11-13 Jim Meyering <meyering@redhat.com>
2176 Clean up the rule to create "expr".
2177 * tests/Makefile.am (expr): Don't redirect directly to target.
2178 Redirect just once, not for each echo statement.
2179 Use $@, not literal "expr".
2181 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2183 Don't worry about preprocessor when testing long long.
2184 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2185 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2186 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2187 These no longer check for preprocessor flaws.
2188 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2189 Do not check for preprocessor flaws.
2191 2007-11-13 Jim Meyering <meyering@redhat.com>
2193 Adapt dependencies, now that a version change doesn't modify configure.ac
2194 * GNUmakefile: Remove "make clean" kludge.
2195 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2197 Don't redirect directly to target.
2198 Use $@, not literal "version.m4".
2200 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2202 * doc/autoconf.texi (Making testsuite Scripts): Document
2203 ":;{" shorthand as in previous patch.
2205 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2207 * doc/autoconf.texi (Limitations of Builtins): Document problem
2208 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2210 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2211 Use ":;{" shorthand.
2212 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2214 2007-11-12 Jim Meyering <meyering@redhat.com>
2216 Add more non-srcdir build support.
2217 * GNUmakefile (dummy): Split a long line.
2218 Add -v option to autoreconf invocation.
2220 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2221 * GNUmakefile (dummy): Remove INSTALL.
2223 Remove racy commands to build scripts in bin/ and tests/.
2224 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2225 are guaranteed to be built, remove the rules that tried to build
2226 them. Before, with a parallel build, these rules could lead to
2227 two processes writing tests/wrapper.in concurrently.
2229 Build in man/ only *after* building in bin/ and tests/.
2230 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2231 in both bin/ and tests/.
2233 Accommodate non-srcdir build-from-checkout.
2234 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2235 Use git's --git-dir=$srcdir/.git option.
2236 Add quotes, in case tarball_version_file contains shell meta-characters.
2237 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2238 * configure.ac: Pass "." to git-version-gen.
2240 Avoid spurious test failures due to version skew.
2241 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2243 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2245 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2246 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2247 Remove conftest.dSYM directory.
2248 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2249 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2250 Remove `conftest.*' recursively.
2251 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2252 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2254 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2256 Report and analysis by Jeff Squyres and Peter O'Gorman.
2258 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2260 Fix typos in variable names.
2261 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2263 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2265 Document that $((expression)) is not portable.
2266 * doc/autoconf.texi (Shell Substitutions): Here.
2268 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2270 Ignore configure --help* errors due to LINENO-impaired shells.
2271 * tests/torture.at (Configuring subdirectories, Deep Package):
2272 In the --help* tests in read-only trees, make `.' temporarily
2273 writable again for the `stderr' file, and ignore errors due to
2274 the attempt to write configure.lineno.
2275 Report by Patrick Welche.
2277 2007-11-10 Jim Meyering <meyering@redhat.com>
2279 Generate package.m4 in build-dir, not srcdir.
2280 * tests/Makefile.am (package.m4): Adjust target.
2281 Don't redirect directly to $@.
2282 (CLEANFILES): Add package.m4.
2283 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2285 When running $(AUTOTEST), search "." before searching $(srcdir).
2287 Avoid a race condition that would make parallel "distclean" fail.
2288 * tests/Makefile.am (distclean-generic): Replace the default,
2289 automake-provided rule with an identical one, but with an additional
2290 dependency on distclean-local. Simply adding the dependency would
2291 cause automake not to emit the rule at all.
2292 * BUGS: Building with -jN works, now.
2294 Distribute git-version-gen.
2295 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2296 since GNUmakefile is distributed, and requires it for dist* rules.
2298 Remove two more generated files from version control.
2299 * INSTALL: Remove generated file.
2300 * lib/autoscan/autoscan.list: Remove generated file.
2302 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2304 * GNUmakefile (PATH): Remove stray apostrophes; they become
2305 part of PATH, which isn't wanted here.
2307 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2309 New config files output variable `top_build_prefix'.
2310 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2312 * doc/autoconf.texi (Preset Output Variables): Document it.
2314 Report by Bob Friesenhahn.
2316 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2317 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2318 function, to parametrize arithmetic with expr vs. the shell.
2319 Use it where possible.
2320 Suggestion by Benoit Sigoure.
2322 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2324 Adjust the documentation of autotest WRT atlocal.
2325 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2326 when using Automake, to write a rule to produce atlocal, since it's
2327 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2328 distributed, not atconfig.in.
2330 2007-11-04 Eric Blake <ebb9@byu.net>
2332 Update list information.
2333 * README: Mention new autoconf-commit list.
2334 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2336 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2338 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2340 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2342 * build-aux/.gitignore: Ignore mkinstalldirs.
2344 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2346 2007-11-03 Jim Meyering <meyering@redhat.com>
2348 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2349 * build-aux/git-version-gen: This syncs from coreutils.
2351 Adjust the build procedure so "make check" works reliably.
2352 * README-hacking: Include an extra step between "make" and
2353 "make check" to ensure that the latter passes.
2355 Use just-built tools, when possible.
2356 * GNUmakefile (PATH): Set and export here, ...
2357 (dummy): ... rather than here.
2359 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2360 and Andreas Schwab <schwab@suse.de>
2362 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2365 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2367 * configure.ac (AC_PREREQ): Require version 2.60, for
2368 AC_PROG_SED, AC_PROG_GREP.
2370 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2371 and Jim Meyering <meyering@redhat.com>
2372 and Andreas Schwab <schwab@suse.de>
2373 and Eric Blake <ebb9@byu.net>
2375 Document a bug in GNU Bash with compound commands and redirections.
2376 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2377 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2380 2007-11-03 Eric Blake <ebb9@byu.net>
2382 Support m4 1.4.5 in testsuite.
2383 * tests/torture.at (Define a newline): Exclude line numbers in
2385 Reported by Ralf Wildenhues.
2387 2007-11-03 Jim Meyering <meyering@redhat.com>
2389 Remove automake-provided files from version control.
2390 * build-aux/elisp-comp: Remove file.
2391 * build-aux/install-sh: Remove file.
2392 * build-aux/missing: Remove file.
2393 * build-aux/mdate-sh: Remove file.
2394 * build-aux/.gitignore: New file.
2395 Suggestion from Ralf Wildenhues.
2397 2007-11-03 Eric Blake <ebb9@byu.net>
2399 Adjust version comparison to account for git snapshot numbers.
2400 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2401 component separator.
2402 * doc/autoconf.texi (Number processing Macros)
2403 <m4_version_compare>: Document this change.
2404 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2406 2007-10-30 Bruno Haible <bruno@clisp.org>
2408 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2409 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2410 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2411 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2412 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2413 Suggested by Paul Eggert.
2415 2007-10-28 Jim Meyering <meyering@redhat.com>
2417 * README-hacking: Autoconf, Automake, and Perl are required to build.
2418 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2420 2007-10-28 Jim Meyering <meyering@redhat.com>
2422 README-hacking: Recommend running autoreconf -vi.
2423 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2424 so that we use just-built tools when they're available.
2425 Suggestions from Ralf Wildenhues.
2427 2007-10-28 Jim Meyering <meyering@redhat.com>
2429 Make inter-release --version output more useful.
2431 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2432 which indicates that it is built using the 19th change set
2433 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2434 is a prefix of the commit SHA1.
2435 * build-aux/git-version-gen: New file.
2436 * configure.ac: Run it to set the version.
2437 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2438 * Makefile.am (dist-hook): Arrange so that .version appears only
2439 in distribution tarballs, never in a checked-out repository.
2440 * .gitignore: Add .version here, too. Just in case.
2441 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2442 not configure.ac, now that the version number changes automatically.
2444 Ensure that $(VERSION) is up to date for dist-related targets.
2445 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2446 git-version-gen doesn't match $(VERSION), but only for dist targets.
2448 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2450 Fix `Deep Package' failure with a configure script early in PATH

2452 Report by Jim Meyering.
2454 2007-10-27 Jim Meyering <meyering@redhat.com>
2456 Remove all generated files from version control.
2457 * aclocal.m4: Remove.
2458 * configure: Remove.
2459 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
2460 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
2461 * README-hacking: New file: how to build from just-checked-out sources.
2463 2007-10-23 Eric Blake <ebb9@byu.net>
2465 Improve corner case of m4_expand.
2466 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
2468 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
2469 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
2472 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
2474 * doc/make-stds.texi: Update from gnulib.
2476 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2477 and Eric Blake <ebb9@byu.net>
2479 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
2480 problem reported by Bruno Haible in
2481 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2483 2007-10-22 Eric Blake <ebb9@byu.net>
2485 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2488 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2490 Don't check for bug in HP-UX 11.00 cpp.
2491 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2492 Use -1ull rather than -1u, since that causes problems with gnulib; see
2493 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
2495 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2500 (Multiline parenthetical command substitution): Fix typos in
2503 2007-10-21 Eric Blake <ebb9@byu.net>
2505 * configure: Regenerate.
2507 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2509 Fix config status generation with Tru64 ksh.
2510 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix
2511 escaping of backslash in here-documents.
2513 Fix `Deep Package' test failure on FreeBSD.
2514 * tests/torture.at (Deep Package): Do not add `.' to $PATH
2515 unnecessarily. Do not try running `/bin/sh configure' with a
2516 configure script to be found in $PATH, if the shell does not do
2517 this resolution. Fixes test failure on FreeBSD.
2519 Fix config header generation with AIX awk.
2520 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2521 script, use helper array D_is_set, as `" 0"' does not evaluate

3553 * lib/autotest/general.m4 (AT_INIT): Don't set PATH to the empty

3702 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
3703 for a.* when searching for executables, as this prevents users

3717 AC_CHECK_TYPE, AC_CHECK_TYPES.
3718 * doc/autoconf.texi (Generic types): C types must be type-names
3719 (the C terminology), not type-ids (the C++ term). C++ types
3720 must not be anonymous.
3721 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3722 for C++; this drops support for anonymous struct and union types,
3723 which were problematic anyway.
3724 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even

3743 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3744 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3745 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3746 works but the latter doesn't, then it's a valid type.
3747 This lets people use function types and so forth.
3748 For C++ there doesn't seem to be a simple solution, so leave it alone.
3749 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3750 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3751 AC_CHECK_TYPE; that wasn't documented or necessary.

3804 nonstandard grep R.E. escape sequences.
3806 2007-03-17 Jim Meyering <jim@meyering.net>
3808 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3809 (Limitations of Usual Tools): Also list \< and \>, and mention that
3810 HP-UX's grep, like the one from Solaris, does not support that syntax.
3812 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3814 * doc/autoconf.texi (Specifying Names): `--host' does not
3815 change the build type.

3921 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3922 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3923 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3924 substitution will still be done by the special code.
3925 Report by Jim Meyering.
3927 * doc/autoconf.texi (File System Conventions): Mention that
3928 $PATH_SEPARATOR is for the build system only.

3998 rewrite, taking notions from the recent discussion on the gcc and
3999 autoconf mailing lists; please see
4000 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4001 and follow the many links.
4002 (Integer Overflow Basics, Signed Overflow Examples):
4003 (Optimization and Wraparound, Signed Overflow Advice):
4004 (Signed Integer Division): New sections.
4006 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4008 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4009 preprocessor macro arguments in traced name.
4010 * doc/autoconf.texi (Defining symbols): Document longstanding
4011 support for AC_DEFINE-ing macros with arguments, and document
4012 behavior when the same variable has multiple AC_DEFINEs.
4013 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4014 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4015 macros directly, giving much shorter and simpler code.
4017 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4019 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4020 space before "$ac_configure_args" to prevent a 'config.status
4021 --recheck' failure if ac_configure_args doesn't contain a leading
4022 space. This works around a problem with the XEmacs configure.ac,
4023 which uses the (undocumented) ac_configure_args variable
4024 inconsistently with Autoconf.
4026 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4028 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4029 Include <limits.h>, and use its INT_MAX to rewrite the
4030 j loop so that it does not overflow 'int'. Problem reported by
4032 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4033 Play it safe by shifting left by 1 rather than multiplying by 2,
4034 as GCC is less likely to optimize this away when the value
4035 is signed (when it assumes overflow leads to undefined behavior).
4036 Also, don't assume time_t uses two's complement.
4038 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4040 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4041 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4042 dumps core on it. Report by Tim Rice.
4044 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4046 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4047 --disable-option-checking to --help output even when
4048 AC_PRESERVE_HELP_ORDER is not used.
4049 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4050 --with argument, rather than argument with [-.] replaced by
4052 * NEWS: Fix typo in previous change; the news was in the
4055 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4057 * NEWS: Warnings are now generated by default for unknown
4058 --enable-* and --with-* options.
4059 * doc/autoconf.texi (Option Checking): Renamed from
4060 (Configure Option Checking). Tighten up the wording a bit.
4061 (External Software, Package Options): Cross-reference to Option
4062 Checking, and use this to shorten our section.
4063 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4064 "$x" to test "x$foo" != x.
4065 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4066 Don't warn if $enable_option_checking is "no".
4067 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4068 ac_unrecognized_opts to the empty string.
4069 Don't echo the unrecognized opts, as this might mishandle
4070 backslashes or leading -.
4071 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4072 usage next to the other --disable-FEATURE options in the
4075 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4077 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4078 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4079 Print warning for unrecognized --with and --enable options
4080 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4081 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4082 Disable option checking when subdirs are configured.
4083 (AC_OUTPUT): If warnings are enabled, print warning about
4084 unrecognized --with and --enable options at the end of
4085 the configure output (as well as at the beginning).
4086 * doc/autoconf.texi (Option Checking): New node.
4087 Document new option warning functionality.
4089 2006-12-16 Eric Blake <ebb9@byu.net>
4091 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4092 * NEWS: Start news for current version.
4094 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4096 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4097 Define HAVE_GETMNTENT to 1, not to the empty string.
4098 Problem originally reported by Jochen Friedrich in
4099 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4101 This change prompted by a problem report by Andrey Simonenko in
4102 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4103 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4104 object-like macros only, in the traditional portable character
4106 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4107 Warn about attempts to define things that are not identifiers.
4108 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4109 awful hack that AC_DEFINEd macro names containing parentheses.
4111 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4113 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4114 too drastic, even if Texinfo in theory requires it for info mode.
4116 (config.status Invocation): Renamed back from Recreating a
4118 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4119 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4121 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4123 * NEWS: Version 2.61a.
4125 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4126 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4128 * NEWS: Document changes with echo and printf, and the lack
4129 of limits on the total size of multi-line values of substituted
4130 variables, and the AC_FUNC_FSEEKO fix.
4132 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4134 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4135 Writing configure.ac.
4136 (Autoconf Input Layout): Renamed from configure.ac Layout.
4137 (Recreating a Configuration): Renamed from config.status Invocation.
4138 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4139 (acconfig Header): Renamed from acconfig.h.
4140 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4141 (Writing Testsuites): Renamed from Writing testsuite.at.
4142 (Autom4te Cache): Renamed from autom4te.cache.
4144 * BUGS: Remove mention of VPATH problem, since it's now documented
4145 not to be a bug in the Autoconf build procedure itself, but rather
4146 a problem with the proprietary `make' programs.
4148 * doc/autoconf.texi (Build Directories): Add a cross reference
4151 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4152 * doc/standards.texi: Sync from gnulib.
4154 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4155 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4156 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4157 generated automatically.
4159 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4161 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4162 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4163 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4165 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4167 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4168 `CEOF$ac_eof' special marker, the awk script cannot contain a
4169 line matching `^CEOF', so this is not needed any more.
4170 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4171 special marker in the test.
4173 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4175 * tests/tools.at (autom4te preselections): Use `find -newer';
4176 remove one of the sleeps.
4178 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4179 more readable, using ...
4180 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4182 * doc/autoconf.texi (autoheader Invocation): Do not double-
4183 quote the parameter of `AH_BOTTOM' in the example.
4185 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4187 * doc/autoconf.texi (Configuration Headers): Remove the
4188 example with multiple input files.
4189 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4190 multiple input files.
4192 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4194 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4195 creating the awk substitution script, handle one input line at a
4196 time, so that the maximum length of a substituted (multi-line)
4197 value is not limited by the size of the sed pattern space.
4198 The trade-off is a slightly repetitive sed script.
4199 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4200 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4201 * tests/torture.at (Substitute a 2000-byte string): Increase the
4202 test with several long lines, they should not be caught by sed
4205 * tests/tools.at (autom4te preselections): New test, to flag
4206 entries missing from autom4te.cfg.
4207 Report by David Byron <dbyron@hheld.com>.
4209 * tests/torture.at (Substitute a 2000-byte string): Actually use
4210 AC_PROG_AWK, so the last change works as intended.
4211 (Substitute and define special characters): Likewise.
4212 (Substitute a newline): Likewise.
4214 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4215 instead of `awk' consistently.
4216 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4217 * tests/torture.at (Torturing config.status): Test both the
4218 result of AC_PROG_AWK and plain awk.
4219 (Substitute a 2000-byte string): Likewise.
4220 (Substitute and define special characters): Likewise.
4221 (Substitute a newline): Likewise.
4223 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4225 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4226 can be assigned to a function pointer. Problem reported by
4227 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4228 part of a patch by Ralf Wildenhues in that same bug report.
4230 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4232 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4233 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4235 2006-12-01 Eric Blake <ebb9@byu.net>
4237 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4238 cross-compiling from cygwin to mingw.
4239 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4240 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4241 to lib/autoconf/c.m4.
4243 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4245 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4246 string for more reliable failure. Wrap the entire test that
4247 causes the broken Solaris printf to dump core, in a subshell,
4248 so the segmentation fault message is reliably suppressed.
4249 Fix shell expansion errors by using /usr/ucb/echo always;
4250 avoid an error on systems without it by another subshell.
4251 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4252 subshell-$as_echo to `as_echo', for better error message.
4254 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4256 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4257 `BASH_SOURCE' contain a newline, set them to empty, as they may
4260 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4262 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4263 years and is too hard to maintain now. The last straw was
4264 reported by Jerker Baeck in
4265 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4266 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4267 * doc/autoconf.texi (Particular Functions): Move
4268 AC_FUNC_SETVBUF_REVERSED from here...
4269 (Obsolete Macros): ... to here. Say that it does nothing now.
4270 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4271 Turn into (almost) a no-op.
4273 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4275 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4276 These macros are obsolescent and new applications shouldn't need them.
4277 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4278 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4279 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4280 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4281 (AC_FUNC_VPRINTF): Likewise.
4282 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4283 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4284 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4286 * doc/autoconf.texi (Setting Output Variables): Mention that
4287 @VAR1@VAR2 has unspecified behavior. Problem reported by
4289 * NEWS: Mention this.
4291 * Makefile.am: Put only a single '#' into the copyright notice,
4292 so that it's also present in the output file. Standardize wording
4293 in makefile copyright notices to match GNU coding standards.
4294 * bin/Makefile.am: Likewise.
4295 * doc/Makefile.am: Likewise.
4296 * lib/Makefile.am: Likewise.
4297 * lib/freeze.mk: Likewise.
4298 * lib/autoconf/Makefile.am: Likewise.
4299 * lib/autoscan/Makefile.am: Likewise.
4300 * lib/autotest/Makefile.am: Likewise.
4301 * lib/m4sugar/Makefile.am: Likewise.
4302 * man/Makefile.am: Likewise.
4303 * tests/Makefile.am: Likewise.
4304 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4307 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4309 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4310 in the sed script that mangles the awk script: delete up to the
4311 first exclamation mark only.
4312 * tests/torture.at (Substitute and define special characters):
4315 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4317 Rewrite config files generation: avoid quadratic growth in
4318 the number of substituted variables by using awk instead of sed
4319 for the bulk of the substitutions.
4320 * NEWS: Mention this.
4321 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4322 forbidden in the output (and thus input) file.
4323 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4324 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4325 generate just one large awk script for substitutions,
4326 eliminating much of the earlier complexity, while adding some
4327 new complexity. Only expand the substitution templates at
4328 configure time, for smaller configure script size. If
4329 _AC_SUBST_FILES are used, test 'awk' for working getline support
4330 at config.status time. If absent, interpolate through the
4331 shell. The awk script was written with much help
4332 from Paolo Bonzini and Paul Eggert.
4333 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4334 (_AC_SED_FRAG_NUM): Likewise.
4335 (_AC_SUBST_CMDS): Renamed from...
4336 (_AC_SED_CMDS): ...this.
4337 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4338 * tests/torture.at (Substitute a 2000-byte string): Also
4339 substitute a line with 1000 words, and a variable with several
4341 (Substitute and define special characters): Test awk special
4342 characters, and put substitution input strings `@foo@' in the
4343 output, to test that no recursion happens; test several other
4344 combinations from Paolo Bonzini.
4346 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4348 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4349 that replaced echo with AS_ECHO where this wasn't necessary.
4350 Problem reportd by Ralf Wildenhues.
4351 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4352 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4353 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4355 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4357 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4359 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4361 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4362 that traditional Awk lacks 3-arg "split". It has it.
4363 Mention that FS must be a single character, and a few other
4364 99-byte limits of traditional Awk.
4365 Mention that if (i in a) doesn't work with traditional Awk.
4367 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4369 * tests/autotest.at (BSx641-newline in command):
4370 (BS-BS-newline in command, BSx640-newline in command):
4371 (Newline-CODE-BS-newline in command):
4372 (Single-quote-BS-newline in command):
4373 (Single-quote-newline-BS-newline in command):
4374 Use printf '%s\n' instead of echo, for portability to hosts
4375 where echo interprets backslashes. This will break on hosts
4376 that lack printf, but for now let's assume all such hosts
4377 are dead (if not, we should get reports of test failures).
4379 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4381 'echo' has some portability problems, when given a first argument
4382 with a leading '-', or when given any argument containing '\'.
4383 Avoid using 'echo' in these cases.
4384 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4385 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4386 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4387 * lib/autotest/general.m4 (AT_INIT): Likewise.
4388 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4389 argument might be unportable.
4390 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
4391 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
4392 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
4393 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
4394 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
4395 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
4396 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
4397 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
4398 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
4399 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
4400 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
4401 (AC_PROG_MAKE_SET): Likewise.
4402 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
4403 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
4404 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
4405 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
4406 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
4407 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
4408 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4409 * bin/autoconf.as: Redo verbose flag implementation, as the old
4410 scheme wouldn't work with AS_ECHO.
4411 * lib/autotest/general.m4 (AT_INIT): Likewise.
4412 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4413 Don't use ECHO_T, since ECHO_N is now reliable.
4414 * lib/autotest/general.m4 (AT_INIT): Likewise.
4415 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4416 rather than using a here-document to put the script into a file.
4417 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4419 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4420 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4421 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4422 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4423 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4424 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4425 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4426 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4427 operand, as AS_ECHO requires. Avoid double file name expansion.
4428 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.

4535 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4538 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4540 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4541 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4542 Imported from a similar patch to gnulib by Bruno Haible.

4563 and Stepan Kasal <kasal@ucw.cz>
4565 Handle special characters in test case titles correctly.

4568 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.

4573 Single-quote in a test title,
4574 Double-quote in a test title): Don't expect failure anymore.
4575 (Backslash in a test title): Put a non-whitespace character after the
4576 backslash so that Bourne shells might actually see it as an escape
4578 (Brackets in a test title,
4579 Pound in a test title,
4580 Comma in a test title,
4581 Quoted Macro in a test title,
4582 Macro in a test title,

4585 Macro with double-quote in a test title,
4586 Macro with backslash in a test title): New tests expected to fail.
4587 * tests/torture.at (#define header templates): M4-quote this title in
4588 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4589 The visible effect was a stray [] in the testsuite output.
4591 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4593 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4594 `trap ... 0' inside a function, for AIX sh.
4596 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4598 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4599 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4600 5363) simply issues a warning when dividing by zero at compile
4601 time. Problem reported by Elias Pipping.
4603 2006-10-26 Eric Blake <ebb9@byu.net>
4606 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4607 show effect on macros that expand with commas.

4632 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4634 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4635 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4636 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4637 reported by Nelson H. F. Beebe for Coreutils 6.4.
4639 * tests/tools.at (autoconf --trace: user macros): Remove test
4640 for tracing multiline macros, since m4 1.4.7a uses a different
4641 way to number lines. Problem reported by Ralf Wildenhues.
4643 2006-10-24 Stepan Kasal <kasal@ucw.cz>

4668 * doc/autoconf.texi (Caching Results): Likewise.
4669 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4670 AC_CACHE_CHECK_INT, since it's no longer public.
4671 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4672 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4700 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4702 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4703 looking for special shell characters.
4704 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4705 macro defined by AS_VAR_PUSHDEF before passing it as a

4717 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4719 (Imported from Automake.)
4720 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4721 which incorrectly sets the mode of an existing destination
4722 directory. In some cases the unpatched install-sh could do the
4723 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4724 system. We hope this is rare in practice, but it's clearly worth
4725 fixing. Problem reported by Alex Unleashed in
4726 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4727 Also, don't bother to check for -m bugs unless we're using -m;
4728 suggested by Stepan Kasal.

4732 Import this change from Automake:
4734 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4735 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4736 is enabled by default with gnu and gnits strictness.
4737 Report from Bruno Haible.
4739 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4748 Import this change from Gnulib:
4750 2006-09-16 Karl Berry <karl@gnu.org>
4751 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4752 to avoid sectioning errors.
4754 Import these changes from Texinfo:
4756 2006-10-04 Karl Berry <karl@gnu.org>
4757 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

4765 * build-aux/texinfo.tex (\textdegree): New command.
4767 2006-08-12 Karl Berry <karl@gnu.org>

4772 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4774 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4776 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4777 added to the template can get mangled.
4779 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4781 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4782 include the default headers, and redefine obstack_chunk_alloc
4783 and obstack_chunk_free. Fixes false failure with glibc.
4785 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4787 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

4800 the NonStop platform.
4801 * doc/autoconf.texi (Posix Variants): Likewise.
4802 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4804 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4805 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4806 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4807 Use a better substitute, by inspecting the output of "ls"
4808 rather than just using ":".
4809 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4810 rather than AS_EXECUTABLE_P, since we needn't worry about
4811 non-regular files here.
4813 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4814 due to configuration hassles with this. See Tonya Underwood's report
4815 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4816 * doc/autoconf.texi (Special Shell Variables): Likewise.

4824 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4826 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4827 initialization which is not inherited through the environment
4828 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4829 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4831 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

4834 problems with mkdir -p -m.
4836 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4838 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4839 comment about ac_cpp_err; it was incorrect, and anyway
4840 ac_cpp_err is being removed below.
4841 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4842 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4843 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4845 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4846 with werror_flag and conftest.err and so forth. This is more
4847 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4848 and anyway the user shouldn't normally want to see this gorp logged.
4849 Problem reported by Ralf Wildenhues.
4850 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4851 empty, not 'no', since the rest of the code uses 'test -z'.
4853 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4855 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4856 Use a single call to AC_DO_TOKENS rather than multiple, for
4858 (_AC_LINK_IFELSE): Test that resulting file is executable.
4859 Problem reported by mwoehlke in
4860 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4862 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4863 than creating a file to use with test -x; this is much faster.
4865 2006-10-02 Bruno Haible <bruno@clisp.org>
4867 * lib/autom4te.in (Automake-preselections): Add
4868 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4870 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4872 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4873 standard error, `experr' should be used, not `expout'.
4875 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4877 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4878 fseeko testing program twice; just use the earlier result.
4879 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4880 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4881 still doesn't let the program compile.
4882 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4885 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4886 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4887 include it, without including anything else.
4888 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4890 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4892 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4894 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4895 `error.h', and include it, for a `error_at_line' prototype.
4896 Use a nonempty format string in the link test.
4897 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4898 for a declaration of wait3.
4900 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4902 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4903 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4904 can apply to constants too, and that it checks for macro defns.
4905 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4906 and simply cast the identifier to void. This handles structure
4907 values. Problem reported by Ralf Wildenhues.
4908 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.

5373 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5375 * doc/autoconf.texi (Volatile Objects): New section.
5377 * NEWS: Document previous change.
5379 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5381 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5382 Require that long long int be at least 64 bits wide. C99 requires
5383 this and enough programs depend on it so we should check for it.
5384 Bruno Haible reports in
5385 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5386 that long long int is 32 bits wide with some nonstandard compilers.
5387 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5389 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5391 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5392 to a nonexistent file, so that we don't have to worry about
5393 a local site configuration that doesn't use /usr/local.
5394 Problem reported by Keith Marshall in
5395 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5397 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5399 * doc/autoconf.texi: Be more consistent about using @acronym with
5400 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5401 quite right (it talked about "OSF/Tru64", even though the
5402 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5403 and it even mentioned "OSF 4"!) and at this point there's little
5404 reason to talk about OSF any more, since it died in 1994.
5405 (Specific Compiler Characteristics): Simplify example of
5406 negative-size array.
5407 (File Descriptors): Reorder to make the text flow better.
5408 Remove joke about "appreciate the various levels"; I didn't get it.
5409 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5410 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5411 (File Descriptors, Limitations of Usual Tools):
5412 Tone down the advice against renaming or removing open files.
5413 (Limitations of Usual Tools): Add a new section, on 'rm'.
5415 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5417 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5418 -lXt in LIBS, idea from Karsten Hopp; this was due since
5421 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5422 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5423 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5424 (which belong to Xt, not X itself). See Debian bug 327655.
5426 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5428 * configure.ac (AC_INIT): Bump to 2.60a.
5431 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5435 * configure.ac, NEWS: Update.
5437 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5439 * config/texinfo.tex: Sync from upstream.
5441 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5442 quadrigraph correctly in traces.
5444 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5447 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5448 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5450 * doc/autoconf.texi (Changed Directory Variables): New node,
5451 to document the whole `datarootdir' business a bit better.
5453 * tests/torture.at (datarootdir workaround): Extend test.
5454 Prompted by report by Alexandre Julliard.
5456 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5458 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5459 when using default mode of IBM C 6 for AIX. Problem and two-line
5460 fix reported by Larry Jones.
5462 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5464 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5465 about literal '${datarootdir}' if a definition is found in the
5468 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5470 * NEWS: Use "M4" rather than "m4" when appropriate.
5471 Problem reported by Eric Blake.
5472 * doc/autoconf.texi: Likewise.
5473 Use @acronym around BSD, GCC, and GNU when appropriate.
5474 (Why GNU M4): Renamed from "Why GNU m4".
5475 (Redefined M4 Macros): Mention that Posix
5476 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5477 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5480 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5482 * bin/autom4te.in (handle_output): Do not forbid the empty
5484 * tests/tools.at (autoconf: the empty token): New test.
5486 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5488 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5489 calls, so that we do not care whether they are LIFO or FIFO;
5490 in the m4_wrap, do not check which diversion is the topmost
5491 one, just check that the stack is balanced at the end.
5492 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5493 base diversion forever--pop the previous diversion before
5494 opening the new one; consequently, remove the m4_wrap call.
5495 * lib/autotest/general.m4 (AT_INIT): Likewise.
5496 * tests/m4sugar.at: Do not use
5497 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5499 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5500 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5502 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5503 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5504 Rework example of m4wrap token-pasting trouble so that it doesn't
5505 care whether it's LIFO or FIFO.
5506 Fix some "contrary to"s that are awkward in English.
5508 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5510 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5511 to `yes' instead of `int$1_t' if the type is found, for more
5512 consistent configure output (where $1 is the number of bits).
5513 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5514 Suggested by Bruno Haible.
5516 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5517 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5518 with system headers. Report by Bruno Haible.
5520 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5522 * config/config.guess, config/config.sub: Sync from upstream.
5524 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5525 in order to avoid picking up an older installed frozen m4sh.m4f.
5526 Besides an outdated shell startup, this could have been created
5527 by an earlier M4 version with incompatible frozen file format.
5529 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5531 * README: Recommend m4 1.4.4 instead of 1.4.3..
5532 * doc/autoconf.texi: Likewise.
5533 (Special Chars in Names): Say that $(.FOO) is portable, as
5534 suggested by Stepan Kasal.
5535 (Installation Directory Variables, Build Directories):
5536 (Automatic Remaking, Subdirectories, Fortran Compiler):
5537 (Making testsuite Scripts, Defining Directories):
5538 Quote variable usages better.
5539 (Making testsuite Scripts): Add clean-local rule to makefile
5540 snippet, by Eric Blake.
5541 (Installation Directory Variables): Fix table item font.
5542 Reword slightly to clarify. Generalize advice about
5543 not using special characters to include all file-related
5544 vars, not just VPATH.
5545 (Special Chars in Variables): Warn about special characters in
5547 (Assignments): Clarify default-value example as suggested by
5549 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5550 (Special Shell Variables): Note leading ./ or ../, as suggested
5552 (Limitations of Builtins): Under cd, warn about CDPATH.
5553 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5556 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5558 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5559 `@var', for texi2html.
5560 (Systemology): Some more word wrapping, for DVI output.
5561 (autom4te Invocation): The short option for `--melt' is `-M',
5564 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5566 * doc/autoconf.texi: More formatting and English tweaks,
5567 many suggested by Ralf Wildenhues.
5568 Reword to avoid "@code{...}'s" and the like, since it's ugly
5569 with Emacs info mode. discontents -> woes.
5570 Put a few "will"s back. time stamp -> timestamp.
5571 side-effect -> side effect.
5573 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5575 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5576 Warn about $@ not persisting. Problem reported by Julien Danjou in
5577 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5578 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5579 Mention other special chars, too.
5581 2006-06-14 Eric Blake <ebb9@byu.net>
5583 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5585 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5587 * doc/autoconf.texi: Some systematic minor improvements, as
5588 follows. Use "makefile" when talking about makefiles
5589 generally (which might be named "makefile" or "Makefile" or even
5590 "foo.mk"), "Makefile" when talking about a specific makefile
5591 called "Makefile". This unclutters the text from weird quotes
5592 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5593 values" rather than "@var{foo}s" and similar constructs containing
5594 "}s". Use "Make rules" rather than "Makefile rules". Minor
5595 English-language improvements. Change the prefix "sub-" to "sub"
5597 Put blank lines around examples more consistently.
5598 Avoid "rather" and "very" as intensifiers.
5599 Avoid "will" as an auxiliary.
5600 (Limitations of Make): Split this node into....
5601 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5602 (Leading _ in Macro Names, Backslash-Newline-Newline):
5603 (Backslash-Newline Comments, Long Lines in Makefiles):
5604 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5605 (obj/ and Make, make -k Status, VPATH and Make):
5606 (VPATH and Double-colon, $< in Explicit Rules):
5607 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5608 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5609 New nodes, resulting from splitup of Limitations of Make.
5610 All cross-references changed. Raise the top node from
5611 a section to a chapter, and all subnodes accordingly.
5612 Redo the introductory wording to match the new organization.
5613 (Installation Directory Variables): Use an example that is
5614 closer to what Autoconf actually does. Mention that VPATH's
5615 value should not contain metacharacters or white space.
5616 (Fortran Compiler): Fix a VPATH bug in an example.
5617 (Leading _ in Macro Names): Mention that this problem is no longer
5618 of practical concern.
5619 (VPATH and Make): Reword the advice to make it clearer
5620 that Autoconf and Automake support VPATH in non-GNU make, but
5621 many packages have bugs in this area.
5622 ($< in Explicit Rules): Refer to Build Directories rather
5623 than using a (non-VPATH-safe) example.
5624 (Automatic Rule Rewriting): Mention the sort of disaster that
5625 can ensue with Solaris-style rule rewriting with VPATH.
5627 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5629 * doc/install.texi (Compilers and Options): Weaken the
5630 suggestion to use GNU make for VPATH builds.
5632 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5633 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5635 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5636 in regular expression.
5638 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5640 * doc/autoconf.texi (Installation Directory Variables):
5641 Drop extra @samp from `@table @samp' item.
5642 (Limitations of Usual Tools): Comment fix.
5643 Do not nest @samp just to point to other table items.
5644 (Writing testsuite.at) <AT_CHECK>: The second argument to
5645 `@dvar' is already @samp'ed.
5646 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5647 do not use @var in the second argument.
5649 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5651 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5652 $as_shell.exe too. Problem reported by Andreas Buening in
5653 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5655 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5657 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5658 `unused variable' compiler warning, for `-Wall -Werror'.
5659 Reported by Jaap Haitsma in
5660 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5662 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5664 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5665 case the compiler dumps core. Problem reported for
5666 OpenServer 5.0.7 by Tim Rice in
5667 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5668 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5671 2006-06-06 Tim Rice <tim@multitalents.net>.
5673 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5674 "ERROR" only shows up in "make check" output if there is an

5679 * tests/tools.at (automatically allowed tokens): Fix typo.
5681 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5683 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5685 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5686 typically overflows on x86 CPUs, even though the C standard
5689 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5691 * configure.ac (AC_INIT): Bump to 2.59e.

5698 * config/texinfo.tex: Sync from upstream.
5700 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5701 seen, invoke libtoolize with `--ltdl' argument.
5702 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5704 Suggested by Eric Blake.
5706 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5708 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

5723 message issued by AC_REQUIRE.
5724 * tests/m4sugar.at: Check m4_require's error message.
5725 * tests/base.at: Check AC_REQUIRE's error message.
5726 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5728 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5730 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5731 `expout' as the last parameter.
5732 * tests/tools.at: Adapt to the above change.
5734 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5736 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5737 information about race-free implementations of mkdir.

5746 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5748 * NEWS: GNU make now recommended for VPATH builds.
5749 Mention that some macros are now documented to be obsolescent.
5750 * doc/autoconf.texi:
5751 Prefer "current" to "modern" to describe
5752 currently-used (albeit perhaps old-fashioned) hosts.
5753 Mention which ancient features no longer need to be worried about.
5754 setgid -> set-group-ID
5755 setuid -> set-user-ID (these are the Posix terms)
5756 Fix some misuses of "only".
5757 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):

5771 Omit longwinded and obsolescent discussion of cp -f.
5772 Modernize discussion of expr, ls.
5773 (Limitations of Make): Modernize discussion of VPATH builds.
5774 Mention $? as a workaround in some cases.
5775 * doc/install.texi (Basic Installation):
5776 Mention "./configure; make; make install" first. Be more
5777 specific about why this file is generic. Remove unnecessary
5778 parens. Remove misleading "only". Remove obsolete advice
5779 about csh. Don't say "configure" takes awhile; say it
5780 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5781 and CC=c99 rather than CC=c89, as these are blessed by current
5782 Posix. Recommend GNU make if doing a VPATH build.
5784 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5786 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5787 examples involving shell prompts.

5805 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5807 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5808 about quoting the case statement, just in case.

5826 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5828 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5829 about quoting ac_try: quote all of it, if any of it seems suspicious.
5830 This means we don't have to worry about ${ or sed any more.
5831 Also, double-quote the case statement, to work around misuses via
5832 underquoting as reported by Ralf Wildenhues in
5833 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.

5845 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5847 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5848 since evidently some packages rely on the old, broken behavior.
5849 Problem reported by Ralf Wildenhues in
5850 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5851 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5852 pre-2006-05-26 definitions, but leave in the comments that
5853 these macros are dangerous and should not be used.
5854 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5855 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5856 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5857 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5858 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5860 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5862 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5863 the use of 'tr', since this is our only use of 'tr'.
5865 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5866 and Paul Eggert <eggert@cs.ucla.edu>
5868 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5869 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5871 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5873 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5874 the output file in the `${datarootdir}' test.
5876 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5877 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5879 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5880 mention of `datarootdir' in the input file(s), but literal
5881 `${datarootdir}' in the output file, and we haven't warned yet,
5882 then warn as well: the user may have (erroneously) used
5883 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5884 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5885 * tests/torture.at (datarootdir workaround): Extend this test.
5888 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5889 and Paul Eggert <eggert@cs.ucla.edu>
5891 * doc/autoconf.texi (autoheader Invocation): The first argument to
5892 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5893 alternatives and clear up the language a bit.
5895 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5897 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5898 ac_config_guess, ac_config_sub, ac_configure.
5899 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5900 Fix typo that prevented an unnecessary space from being removed.
5901 Problems reported by Ralf Wildenhues in:
5902 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5904 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5906 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5907 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5908 Don't use the term "thread-safe" to talk about mkdir race
5909 conditions, since the problem is more a process than a thread
5910 issue. Problem reported by Stepan Kasal in:
5911 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5912 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5913 the test for 'install' more closely. Look at MKDIR_P first.
5914 Look in the PATH, and at /opt/sfw/bin.
5915 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5916 Don't bother to try mkdir -p, since we already check mkdir --version;
5917 just look at the version number. (There's no easy way to check
5918 for race-free implementations.)
5919 * tests/tools.at (autoconf: subdirectories): Adjust to above
5920 changes, since MKDIR_P now might end in "/mkdir -p".
5922 * doc/autoconf.texi (autoheader Invocation): Mention that the
5923 first arg of AC_DEFINE_UNQUOTED must be a literal.
5924 Problem reported by Ben Pfaff in
5925 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5927 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5928 * doc/autoconf.texi (Special Chars in Variables): New section.
5929 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5930 (Installation Directory Variables): Quote $(datadir) better.
5931 (Limitations of Builtins): Describe some of eval's trickiness.
5933 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5934 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5935 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5936 in front of every arg, not just trailing args. Quote apostrophes.
5937 (_AC_EVAL_ECHO): New macro.
5938 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5939 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5941 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5942 exposed by quoting of eval argument. Put the command on line line
5944 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5945 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5946 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5947 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5948 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5949 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5950 Use eval more safely.
5951 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5952 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5954 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5955 lines, exposed by quoting of eval argument.
5957 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5958 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5960 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5961 initialization of `ac_cv_exeext', do not override it if it was
5962 already set, unless it was set to `no', for compatibility with
5963 Autoconf-2.13, and comment this.
5964 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5965 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5966 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5967 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5968 Document that this test may be overridden by setting
5971 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5973 Revert these two patches:
5975 2006-04-06 Eric Blake <ebb9@byu.net>
5976 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5977 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5980 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5981 Clean up _AC_COMPILER_EXEEXT* macros.
5982 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5983 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5984 ac_file to the name of the default output file and call
5985 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5986 initial `rm' of the candidate files...
5987 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5988 the same list in subsequent `rm' calls, and for the temporary
5989 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5990 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5991 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5992 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5993 no longer needed) by libtool. Make it a cache check.
5994 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5995 copied here by mistake.
5996 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5997 _AC_COMPILER_EXEEXT.
5998 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5999 _AC_COMPILER_OBJEXT directly.
6000 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6002 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6004 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6005 Fix description of how the buggy `sed' works.
6007 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6011 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6012 ENOLCK. Only mention `make -j' when applicable. Only raise
6013 fatal errors when `make -j' is involved. Improve error message.
6015 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6017 * doc/autoconf.texi (Here-Documents): We now know more about
6018 the variable expansion in here documents bug.
6019 Thanks to Tim Rice and Stepan Kasal.
6021 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6022 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6024 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6026 * tests/autotest.at (Multiline command from M4 expansion):
6027 No failure to be expected if the shell quotes newlines in
6028 commands in the `set -x' output. Report by Tim Rice.
6031 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6033 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6034 expansion in the here-documents used by config.status, as that
6035 runs afoul of the Korn shell version M-12/28/93d bug described in
6036 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6037 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6038 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6040 2006-05-23 Jim Meyering <jim@meyering.net>
6042 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6043 Fix typo introduced with 2006-04-02 change. It reversed the sense
6046 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6048 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6049 ac_dB slightly, to save bytes in the script.
6050 Max out at 50 lines, rather than 96; this is more likely
6051 (though not guaranteed) to avoid obscure 'sed' failures.
6053 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6055 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6056 `tr -d -' as bad option argument. Work around this by deleting
6057 an unrelated character.
6058 Report by Tim Rice <tim@multitalents.net>.
6060 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6061 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6062 Stepan Kasal <kasal@ucw.cz>
6064 * doc/autoconf.texi (Particular Programs): Do not promise that
6065 we always prefer the GNU version of the program, and that we
6066 search according to PATH; both rules can have exceptions.
6067 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6068 AC_PROG_SED. Move descriptions of limitations
6069 to the Limitations of Usual Tools section.
6070 (Limitations of Usual Tools) <sed>: Mention script length
6071 limitations with Solaris /usr/ucb/sed.
6072 <grep>: Fix wording for empty alternative. Mention that -c and
6073 -l should not be combined, and that -E and -F should not be
6076 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6077 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6079 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6080 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6082 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6084 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6085 AC_DEFINE is now passed to m4_pattern_allow.
6086 * NEWS: Mention that; likewise for AC_SUBST.
6087 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6088 the parameter to m4_pattern_allow.
6089 * tests/tools.at: Add a check for that.
6091 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6093 * lib/autoconf/status.m4: Fix typos.
6095 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6097 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6098 only the files that this macro generates.
6100 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6102 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6103 the HP-UX sed limitation of 99 commands, labels do not count.
6104 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6106 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6108 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6110 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6111 Import the following fix from coreutils:
6113 2006-01-13 Jim Meyering <jim@meyering.net>
6115 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6116 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6117 not double-quote uses of that variable, to accommodate the rare
6118 case in which getmntent is available in none of the libraries
6119 checked. This happens at least on FreeBSD 5.0.
6121 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6123 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6124 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6125 some other programs unwisely rely on these undocumented vars.
6126 But put in warning comments about them.
6127 Problem reported by Ralf Wildenhues in
6128 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6129 * NEWS: Document that these variables are intended to go away.
6131 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6133 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6134 and set the language to C++ (analogous to the equivalent Fortran
6137 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6138 * doc/autoconf.texi (C++ Compiler): Document it.
6139 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6142 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6144 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6145 that caused config.status to generate 100-command sed scripts; the
6146 portable limit is 99.
6148 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6150 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6151 variable `ac_d' instead of `d' to avoid infringing namespace.
6152 Report by Ralf Menzel.
6154 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6156 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6157 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6158 * tests/tools.at (autoconf: subdirectories): New test, taken from
6159 the corresponding problem report by Ralf Wildenhues in:
6160 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6162 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6163 Quote some uses of shell variables if they might suffer unexpected
6164 globbing. This doesn't fix all instances of quoting problems that
6165 I found, just the easy ones that look safe.
6166 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6167 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6168 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6169 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6170 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6171 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6172 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6174 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6175 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6177 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6179 * bin/autoreconf.in ($help): Reword according to the manual.
6180 Suggested by Olly Betts.
6182 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6183 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6185 * bin/autoreconf.in: Pass the directory argument to
6186 `require_configure_ac'. Fix comment.
6187 * tests/torture.at (Configuring subdirectories): Expose this.
6188 Reported by Olly Betts.
6190 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6192 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6193 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6194 Automake as follows:
6196 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6197 `$configure_in' instead of `configure.in', to preserve
6198 directory component.
6200 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6202 * config/config.guess, config/config.sub, config/texinfo.tex,
6203 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6205 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6207 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6208 test for C99 conformance; (bool) 0.5 is an integer constant
6209 expression, but (bool) -0.5 is not. Problem reported by Fedor
6210 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6212 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6214 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6215 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6216 Warn about obsolete install-sh files. Remove stray sentence
6217 fragment and fix cross reference.
6218 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6219 install -d; this undoes the 2006-05-10 change.
6220 (MKDIR_P): Mark with AN_MAKEVAR.
6221 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6222 that we don't require $INSTALL to be thread-safe. Move comments
6223 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6224 of AC_PROG_INSTALL. Output a message saying that we're checking
6225 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6226 MKDIR_P instead of AC_SUBST.
6227 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6228 Special magic for MKDIR_P, too.
6229 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6231 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6233 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6235 Sync from Automake, as follows:
6237 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6238 * config/install-sh: Initialize IFS, so field splitting isn't
6240 * config/mkinstalldirs: Likewise.
6241 * config/missing: Remove superfluous quotes. Replace all uses of
6242 `[' by `test', for consistency, and for..
6243 * config/missing (sed_minuso, sed_output): New variables.
6244 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6245 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6246 Fixes `missing' to detect `--output' for help2man. Fixes
6247 PR automake/483. Report by Dennis J. Linse.
6248 (autom4te): Document in `missing --help'.
6250 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6252 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6253 * config/install-sh: Don't use 'path' to talk about file names,
6254 as per GNU coding standards. Close a race condition reported by Ralf
6255 Wildenhues and Stepan Kasal. There is still a race condition
6256 on hosts that predate Posix 1003.1-1992, but we can't help this.
6257 Don't mishandle weird characters like space on pre-Posix hosts.
6258 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6259 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6260 AC_PROG_MKDIR_P from AS_MKDIR_P.
6261 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6262 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6263 earlier editions are not (including Automake 1.8.3).
6264 Do not suggest mkinstalldirs for thread-safety.
6265 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6266 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6267 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6268 presence of special characters and race conditions.
6269 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6270 in Autoconf's name space.
6272 2006-05-10 Bruno Haible <bruno@clisp.org>
6273 and Paul Eggert <eggert@cs.ucla.edu>
6275 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6276 from Automake with minor changes.
6277 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6279 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6281 * config/install-sh: Update to Automake CVS version, as follows:
6282 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6283 * lib/install-sh: Simplify the expr implementation of dirname.
6284 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6285 * lib/install-sh: Handle --, and diagnose unknown options.
6287 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6289 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6290 `./autom4te' to create `./testsuite', since the `all' target
6291 will ensure its presence, but `installcheck' should not create
6292 the uninstalled wrappers.
6294 * tests/torture.at (Unusual Automake input files): Skip if we
6295 detect automake < 1.8.
6297 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6299 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6300 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6301 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6304 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6306 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6307 munge (multiple) white space and other oddities.
6308 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6309 single quotes in variable assignment.
6310 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6311 and similar failures by adding multiple spaces, tabs, and other
6313 Report and different test suggested by Francesco Romani
6314 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6316 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6317 single quotes, we only need to search for single quotes; this
6318 both simplifies the search pattern, and makes us less
6319 susceptible to `echo' variations for arguments not containing
6321 (_AC_ARG_VAR_VALIDATE): Likewise.
6323 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6325 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6326 `$*' and IFS concatenation issue with traditional shells and
6327 bash-2.04. Report by Seanster@Seanster.com.

6331 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6332 precisely which Mac OS X versions have the od problem.
6334 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6336 * doc/autoconf.texi: Use @option systematically.
6338 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>

6341 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6343 (Integer Overflow): Mention the special case of integer division
6346 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6348 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6349 traditional shells like the Solaris one that do not use the
6350 first IFS character for assembling `$*'.
6351 Prompted by a related report from autoconf_bug@nro.ca.
6353 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6354 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6375 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6376 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6377 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6379 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6381 * doc/autoconf.texi (Limitations of Make): Clean up markup.

6387 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6389 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6390 /bin/sh set unsorted output.

6399 (Writing Test Programs): Fix some langauge. Recommend exiting
6400 with status 1, not merely nonzero. Clarify exit declaration.
6401 (Run Time): Move C exit status stuff to new Exiting Portably section.
6402 (Systemology): Mention Posix and levenez. Update v7 reference.
6403 (Portable Shell): Mention the Posix shell.
6405 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6407 * bin/autoconf.as (me): Replace by as_me.
6409 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6411 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6412 since as_me isn't set yet.
6414 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6416 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6417 a few minor bugs in this area.
6419 * doc/autoconf.texi (Programming in M4sh): Comment out the
6420 documentation of AS_BASENAME, for now.
6421 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6422 (Limitations of Builtins) <basename>: Do not refer to
6424 * bin/autoconf.as (me): Don't use AS_BASENAME.
6425 (dir): Remove the unused variable.
6426 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6427 AS_DETECT_REQUIRED. All uses changed.

6435 (_AS_DIRNAME_PREPARE): Likewise.
6436 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6437 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6438 (AS_DIRNAME): Use "dirname --".
6440 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6442 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6443 of "run time" and "run-time" changed to "runtime", for consistency.
6444 * lib/autoconf/fortran.m4: Likewise (in comment).
6445 * lib/autoconf/functions.m4: Likewise.
6446 * lib/autoconf/general.m4: Likewise.
6447 * lib/autoconf/headers.m4: Likewise.
6449 * doc/autoconf.texi (Run Time): Document the exit status situation
6450 with more accuracy and detail.
6452 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6454 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6455 Archive is not officially `GNU' any more. Update URL.
6456 (Defining Directories): Likewise
6457 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6459 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6461 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6462 newline from the `trap' code to finish `config.log'; the NetBSD
6463 /bin/sh resets the exit status after an empty command, as
6464 documented in doc/autoconf.texi.
6465 Reported by Dalibor Topic <robilad@kaffe.org>.
6467 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6469 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6470 Suggested by Bruno Haible.
6472 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6474 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6475 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6476 Instead, just list the shells that we know work.
6477 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6478 changed. Be more cautious about the _cv_ variable.
6479 * tests/tools.at (Syntax of the shell scripts): Check the
6480 _cv_ variable once, at first, to avoid an internal autoconf error
6481 when sh -n does not work.
6483 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6485 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6487 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6489 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6490 use ">&-" since we're only 99.999% sure that this is portable,
6491 and since the MinGW bug is fixed in a different way.
6492 * lib/autotest/general.m4 (AT_INIT): Likewise.
6494 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6496 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6497 before opening config.log, to avoid hitting a bug on MinGW.
6499 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6501 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6502 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6503 This works around a MinGW bug reported by Eric Paire.
6504 Make sure that all writes to the log file append to it,
6505 rather than possibly losing data.
6506 * lib/autotest/general.m4 (AT_INIT): Likewise.
6508 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6510 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6513 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6517 * configure.ac (AC_INIT): Bump to 2.59d.
6519 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6523 * Makefile.maint (news-date-check): Do not require a leading `*'
6524 before the release date in NEWS.
6526 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6527 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6529 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6530 the instantiated file do not contain the string 'datarootdir'
6531 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6532 @mandir@, replace the reference '${datarootdir}' by the value.
6533 * tests/torture.at (datarootdir workaround): New test.
6534 * NEWS: Advertise this temporary fixup.
6535 Based on a patch by Bruno Haible, reported and analyzed by
6536 Paul Eggert and Noah Misch.
6538 2006-04-12 Eric Blake <ebb9@byu.net>
6540 * tests/autotest.at (Debugging a failed test): Fix comment.
6542 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6544 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6545 all the changes since 2006-04-07.
6547 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6549 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6550 succeeded, but `ln -s file dir' failed, take care to remove the
6551 leftover target before the next test, to prevent its spurious
6552 failure; also make sure `ln file dir' works before selecting it.
6553 Thanks to Keith Marshall for pointing this out.
6556 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6557 assignments in `at_debug_args', so that we put them correctly
6558 in the `run' script.
6559 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6560 Reported by Eric Blake.
6562 2006-04-11 Eric Blake <ebb9@byu.net>
6564 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6565 top-level tests after micro-suite has been run. Used in...
6566 (Debugging a successful test, Debugging script and environment),
6567 (Debugging a failed test): ...these new tests. The first of these
6569 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6570 macro, split out from...
6571 (AT_INIT): ...here, so that using -d also generates a run script.
6572 Document that -d inhibits top-level logging.
6573 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6574 inhibits top-level logging; debug scripts are created.
6576 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6578 * tests/autotest.at (Empty test, Empty check): New test to check it.
6580 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6583 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6585 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6586 the files if a problem appears. Make the empty *.at files
6587 read-only, too. Proposed by Ralf Wildenhues.
6589 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6591 * config/Makefile.am: Add comment to force updated Makefile.in.
6593 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6594 space only patch to this file, this patch causes the Makefile.in
6595 files that include freeze.mk to be updated, and thus have a
6596 newer time stamp again, which in turn makes a pristine CVS
6597 checkout have correct time stamps.
6599 * Makefile.maint (cvs-sv): New macro, to be used..
6600 (config.guess-url_prefix, config.sub-url_prefix)
6601 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6602 point to CVS text checkout of Gnulib files.
6603 (copyright-check): Bump current year.
6604 (announcement): Do not hard-wire `./announce-gen'.
6605 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6607 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6609 (wget_files): Update config.guess, config.sub, texinfo.tex by
6610 `wget-update', now that their URLs work again.
6612 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6614 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6615 Problem noted by Paul D. Smith.
6617 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6619 * doc/autoconf.texi: Remove unused words from word list.
6620 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6621 .x-sc_trailing_space: New files.
6623 * doc/standards.texi: Sync from gnulib.
6625 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6626 `LIBOBJDIR' as experimental.
6628 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6629 with a target directory; it's internally implemented as `cp'
6630 anyway, but since Autoconf advertises the possibility to use
6631 a target directory when LN_S is `ln -s', we need to find out.
6632 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6633 analyzed by Keith Marshall <keith.marshall@total.com>.
6637 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6639 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6640 confdefs.h as-is. In general, if it has backslash-newline or the
6641 like, then it doesn't work either to sort or to remove empty
6644 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6646 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6648 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6650 * lib/autom4te.in (Automake-preselections): Preselect
6653 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6655 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6656 apostrophe within a single-quoted string, as this is the usual
6657 tradition and is easier to read than '"'"'. Don't rely on the
6658 shell treating "$/" like '$/'. Use a more-consistent indenting
6661 2006-04-09 Eric Blake <ebb9@byu.net>
6663 * tests/autotest.at (Backquote command substitution),
6664 (Multiline backquote command substitution): Remove mistaken
6665 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6667 (Parenthetical command substitution, Multiline parenthetical
6668 command substitution): here.
6670 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6672 Import macros from gnulib (often changing their name).

6703 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6704 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6705 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6706 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6707 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6708 (Coding Style). Don't mention m4_expand_once.

6747 Revert the patch from 2006-04-01 and only improve
6748 _AS_DETECT_BETTER_SHELL:
6750 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6751 skip nonexistent directories.
6752 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6753 only shell candidates which exist.
6754 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6755 * lib/autotest/general.m4 (AT_INIT): No need to give three
6756 parameters to _AS_PATH_WALK.
6758 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6759 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6761 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6762 distinguish m4sugar macros.
6763 * tests/tools.at (autoupdating with aclocal and m4_include):
6764 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6765 test case by Noah Misch <noah@cs.caltech.edu>.
6767 2006-04-07 Stepan Kasal <kasal@ucw.cz>

6778 * doc/autoconf.texi (Programming in M4sh): Document that
6779 AS_MKDIR_P exits the script on failure.
6780 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6782 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6801 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6803 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6804 whether `set' quotes correctly: redirect stderr of the tested
6805 `set', and use a subshell, for Ultrix; use `sed' instead of
6806 `grep' for zsh `set' which may write binary output; match only
6807 at the beginning of a line, to avoid false positives.
6808 In order to avoid false positives by unrelated variables with
6809 multiline content, put the dump algorithm in a subshell and
6810 unset all variables containing newlines (except some which are
6811 special to the shell). Warn about cache variables that are

6856 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6857 ac_config_<foo>s again, sometimes normalized, sometimes not.
6858 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6859 (AC_CONFIG_COMMANDS): Do not do so here.
6860 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6861 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6862 2005-07-25 rewrite. Noticed by Noah Misch.
6864 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6865 _AC_PRESERVE_HELP_ORDER, ...

6868 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

6872 for --help from Cygnus `configure.'
6874 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6922 Use simplified args that Eric Blake originally suggested.
6924 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6926 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6927 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
6928 Use 'comm' rather than N instances of grep; this also fixes a bug

6931 (exclude_list): Exclude empty macros.
6932 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

7018 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7019 initial `rm' of the candidate files...
7020 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7021 the same list in subsequent `rm' calls, and for the temporary

7026 no longer needed) by libtool. Make it a cache check.

7028 copied here by mistake.

7723 CONFIG_SHELL in the environment of the configure rerun.
7724 * doc/autoconf.texi (Here-Documents, config.status Invocation):

7746 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
7747 Factor functionality to..
7748 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7749 `AC_SUBST($1)' in the public version.
7750 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7751 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

7776 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7777 conftest.o, to see whether the compiler really obeys; rm the object
7778 file before and after the test and register it with ac_clean_files.

7804 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7805 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7806 by the function rather than ignoring it.
7807 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7808 comparing its address. Intel's interprocedural optimization was
7809 outsmarting the old heuristic. Problem reported by
7812 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7814 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

7821 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7823 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7824 before removing it (chmod -R u+rwx); there are three instances of this.
7826 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7827 Stepan Kasal <kasal@ucw.cz>
7829 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7830 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7831 make its content writable before removing it. Remove an errorneous
7832 comment from the end, where the logs of the failed tests are copied
7833 to the main log file.
7835 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7837 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7838 in case the computer is too quick. Double quote the configure.ac
7841 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7842 problems if the testsuite were running too fast.
7844 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7846 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7847 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7848 (which belong to Xt, not X itself). See Debian bug 327655.
7849 * NEWS: Mention this.
7851 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7853 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7855 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7857 * config/move-if-change: Don't output "$2 is unchanged";
7858 suggested by Ben Elliston. Handle weird characters correctly.
7860 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7862 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7863 calls, so that the final expansion of this macro is shorter.
7864 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7865 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7866 the cleanup there. Use AS_VAR_* macros, to be more general.
7867 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7869 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7871 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7873 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7875 * doc/autoconf.texi (Configuration Headers): Add an index entry
7878 2005-08-26 Pavel Roskin <proski@gnu.org>

7881 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7884 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7886 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7887 The previous patch didn't work, so try a better one.
7889 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7891 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7892 in the example. Reported by Bruno Haible.
7893 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7894 "if $undefined_var;" succeeds with my shell.
7896 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7897 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7898 but change the m4_divert_text to m4_divert_once.
7900 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7902 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7903 Work around bug in Solaris /usr/xpg4/bin/awk.
7904 The bug is present in at least Solaris 8 through 10.
7906 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7908 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7909 some evil values and relying on the fact that $* concatenates the
7910 parameters by the first character from IFS.
7912 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7913 Stepan Kasal <kasal@ucw.cz>
7915 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7916 first header appears, define AH_HEADER.
7917 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7918 Update limitations about when to call AC_CONFIG_HEADERS.
7919 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7920 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7921 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7922 ``Configuration Actions''; fix their index entries.
7924 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7925 options correctly. Process N-M as M-N if M is smaller than N.
7926 Process ranges correctly so that N-N will run only N.
7927 Sort and uniquify the tests that will be run. If there is more
7928 than one test, reinsert the banners for the tests.
7929 * tests/autotest.at (Keywords): Unmark XFAIL.
7931 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7933 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7934 before passing the macro name to AH_TEMPLATE.
7936 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7937 now opens log after option processing; in particular, --version
7938 and --help do not touch config.log.
7940 * Makefile.maint: Revert the change from 2005-08-12.
7942 2005-08-22 Stepan Kasal <kasal@ucw.cz>

7950 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7951 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7954 * doc/autoconf.texi (Defining Symbols, Changed Results):
7955 Prepend to LIBS, not append, in examples.
7957 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7959 When building in place, set srcdir="."; suggested by Tim Van Holder.
7961 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7962 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7963 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7964 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7965 does not mean "no --srcdir option".
7967 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7969 * tests/autoscan.at (autoscan): New file.

7978 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7979 add "2>&1"; gzip 1.2.4 prints help on stderr.
7981 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7983 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7984 was pushdef'ed twice while popped only once. Push it only once.
7985 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7987 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7989 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

7999 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8001 Rewrite substantial part of lib/autoconf/status.m4.
8002 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8003 and CONFIG_COMMANDS are not processed in four separate loops.
8004 Instead, there is one main loop. This alows that the common code
8005 is expanded only once, thus config.status (and configure) is smaller.
8007 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8008 the AC_LIST_FILES and cousins macros are no longer used.
8010 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8011 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8012 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8013 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8014 contain the initialization, nor the for loop, nor the associated
8015 commands; all these go to ...
8016 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8017 _AC_OUTPUT_CONFIG_STATUS.
8018 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8019 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8020 (_AC_OUTPUT_FILE): The creation of the sed script ...
8021 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8022 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8023 _AC_OUTPUT_MAIN_LOOP.
8024 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8025 _AC_CONFIG_COMMANDS): Use ...
8026 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8027 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8028 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8029 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8030 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8031 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8033 (_AC_CONFIG_UNIQUE): Update.
8034 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8035 Replaced by this ...
8036 (_AC_LIST_TAGS): ... new common macro.
8037 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8038 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8039 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8040 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8041 this didn't belong to the `config commands' section.
8042 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8043 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8044 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8045 to the `config commands' section either.
8046 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8047 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8049 ... and many changes to the comments nearby.
8051 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8052 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8053 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8054 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8055 (#define header templates): The comment at the top of the generated
8056 header now includes the name(s) of the source file(s).
8058 Several unrelated small changes:
8060 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8061 parameter to AC_DIAGNOSE.
8062 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8063 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8064 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8065 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8067 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8068 in AC_OUTPUT doesn't double-quote it either.
8069 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8072 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8074 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8075 versions of Portland Group compiler produce single- and double-quoted
8076 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8077 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8079 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8081 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8082 This is a corrected version of yesterday's patch.
8084 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8086 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8087 path, too; insert a "===" to emphasize the line.
8089 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8090 ac_cv_build_alias to ac_build_alias.
8091 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8093 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8094 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8095 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8096 (AC_ARG_VAR): ... here.
8097 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8100 Keep a list of all precious variables and process them with one simple
8101 for loop, instead of expanding all commands, or, OTOH, complicated
8102 processing of output of "set".
8103 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8104 variable names in new macro...
8105 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8106 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8107 a loop to assign all ac_env_* and ac_cv_env_* variables.
8108 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8110 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8111 its value to shell variable ac_precious_vars and call
8112 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8113 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
8114 _AC_ARG_VAR_VALIDATE.
8116 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
8117 and the AC_SUBSTs ...

8137 2005-07-05 Stepan Kasal <kasal@ucw.cz>
8139 Fix my changes from 2005-07-01; reported by Noah Misch.
8140 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8141 description, the macro now accepts only a single tag.

8147 at_top_builddir, for compatibility with older autotest.
8148 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
8149 is not set, use at_top_builddir, for compatibility with older
8150 versions of autoconf.
8152 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8154 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
8155 Problem reported by Patrick Welche.
8157 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8159 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8160 sed substitution command, so that we allow | in program prefixes
8161 and program suffixes. (& is a problem anyway; we're not fixing
8163 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8164 configure_input, top_builddir, srcdir, etc.
8165 * lib/autotest/general.m4 (AT_INIT): Likewise, for
8166 PATH_SEPARATOR in AUTOTEST_PATH.

8176 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

8198 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
8199 document to output the default config_* lists to config.status.
8200 Don't recognize option --file, if the functionality is not there.
8201 Likewise for --header; moreover, recognize --he and --h as shortcuts
8202 for --help in that case.
8204 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8205 matches the order of execution. No code changed.

8220 descriptors to child processes; reported by Norman Gray.
8222 2005-06-29 Stepan Kasal <kasal@ucw.cz>
8224 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
8226 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
8227 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8228 (AC_SUBST): Call it.
8229 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8230 the directory specific variables; but don't call it for configure_input.
8232 2005-06-28 Derek Price <derek@ximbiot.com>
8234 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8237 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8239 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

8241 due to limitations in Make syntax. Problem reported by Alexandre
8243 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

8256 from Justace Clutter.
8257 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8258 variable into diagnostic. Make the diagnostic an error, not a warning,
8259 because we really don't support spaces and suchlike in dir names.
8260 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8261 Don't worry about backslashes in srcdir; it can't happen now.
8262 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8263 Simplify ac_optarg handling.
8264 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8272 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
8274 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8275 that '\|' is not allowed in BREs; recommend using newline separated
8276 list of patterns instead of multiple -e options.
8278 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8280 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8288 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8289 b, t, r, w commands require single space, while : cannot have any.
8290 (Special Shell Variables): Fix sed code this in the example.
8291 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8292 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8294 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

8300 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8302 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8304 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8305 * doc/autoconf.texi:
8306 Don't mention Solaris versions so much, if a
8307 problem is common to all extant versions of Solaris. Say "SunOS
8308 4" instead of "SunOS" for SunOS 4.
8309 (awk): Mention more of the limitations of traditional Awk.
8310 (cat): Don't talk about cat -v.

8326 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8328 * doc/autoconf.texi: "filesystem" -> "file system".
8329 "behaviour" -> "behavior".
8330 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8331 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8333 * lib/m4sugar/m4sh.m4: Likewise.
8334 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8335 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8337 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8338 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8339 to update the man page. That way, we don't have to check in new

8350 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8352 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8353 -u, since it outputs chatter if the input files are the same.
8354 Problem reported by Ralf Menzel.
8356 2005-06-08 Derek Price <derek@ximbiot.com>
8358 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8359 renaming them since they are about to be redefined anyhow.
8361 2005-06-08 Derek Price <derek@ximbiot.com>
8363 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8364 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8365 Move m4_undefine to alphabetical order.
8367 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8369 * README: Recommend GNU M4 1.4.3 or later.
8370 * doc/autoconf.texi (Introduction): Likewise.
8371 Reword to avoid some formatting glitches.
8372 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8373 Clarify explanation of HP compiler bug.
8374 Redo example output tp match current CVS snapshot.
8375 Use @example.org in email addresses when the examples
8376 might get inadvertently cut-and-pasted into user code.
8377 Remove example of autom4te usage that doesn't seem to work now.
8378 Use modern AC_INIT (except when the example is meant to be
8379 shown with Autoconf 2.13).
8380 Update ksh info for Solaris 9 and later.
8382 Modernize description of Automake versions a bit.
8383 Don't claim a future version of Autoconf is near.

8389 follows its own advice about quoting better.
8390 Reword to avoid some formatting glitches.
8391 * doc/installt.exi: Reword to avoid some formatting glitches.
8393 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8394 Tru64 ksh pattern matching bug. Reported against Libtool by
8395 Albert Chin <libtool@mlists.thewrittenword.com> and
8396 Nicolas Joly <njoly@pasteur.fr>.
8398 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8400 m4_cdr of one-member list was [[]] (one-member list containing an
8401 empty string) instead of [] (an empty list. Callers were skewed to
8402 match this misbehaviour. As a consequence of this:
8403 - m4_foreach([x], [], [foo]) expanded to `foo', while
8404 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8405 This bug has been fixed:
8407 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8408 expand to an empty string; print error msg if called without
8410 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8411 misbehaviour; handle [] and [[]] correctly.
8413 2005-06-06 Stepan Kasal <kasal@ucw.cz>

8419 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8421 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8422 swallow records with more than 99 fields.
8423 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8424 parse the long line.
8426 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8428 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8429 swallow literals longer than 399. Reported by Ralf Wildenhues.
8430 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8431 to workaround this limitation.
8433 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8435 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8436 to gfortran, and make these the first two compiler names
8437 checked (following the general autoconf preference for gcc).

8441 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8442 (DISTCLEANFILES): Remove $(check_SCRIPTS).

8447 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8448 expression of unbounded size when processing the --list
8449 option. This runs afoul of a limit of 399 bytes per regular
8450 expression on AIX. Problem reported by Ralf Wildenhues.
8452 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

8455 * doc/autoconf.texi (Particular Headers): Reword example
8456 for multiline stdbool replacement.
8457 (Setting Output Variables): Reword text a bit. Don't
8458 give all the details about |#_!!_#|.
8459 Reword description of line replacement.
8461 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8463 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8464 now contain newlines, and substituted files must be referenced on
8465 a line alone; the sed scripts to substitute them are now very
8467 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8468 commands can be put in a sed script portably.
8469 * doc/autoconf.texi (Setting Output Variables): Document above
8470 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8471 use of multiline substitution.

8482 classes in shell scripts. The test was too brittle.
8484 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8486 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8487 * doc/autoconf.texi (Limitations of Builtins): Document this
8490 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8492 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8493 common code; used in many places in the tree.

8495 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8497 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.

8500 messages when ac_unique_file is not found.
8501 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8502 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8503 commands, for consistency with AC_MSG_ERROR and such.
8505 * bin/autoconf.as: Make more use of "shift 2" in option processing.

8518 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8519 (ac_top_builddir): ... this ...
8520 (ac_top_build_prefix): ... to this; the old name is also kept, for
8521 backward compatibility.
8522 (ac_top_builddir_sub): New variable, without the trailing slash,
8524 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

8538 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8539 argument to m4_foreach. I guess it was necessary in the past,
8540 but I think it's a no-op now.

8544 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8545 ``cat <<_ACEOF'' commands to one.

8551 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8553 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8554 the wrong patterns between ``case'' and ``esac.'' The previous
8555 code had false positives.

8624 quoting rules. Problems noted by Stepan Kasal.
8625 Also, throughout this document, be more careful about white space.
8626 "blank", "white space", and "space" all have different meanings
8627 and we should be careful to say what we mean.

8647 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8648 set by latest automake.
8650 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8652 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8653 outputs 0 on GNU/Linux these days.

8666 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8667 by AC_DEFINE; it was a mistake.
8668 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8670 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8672 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8674 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8676 * doc/autoconf.texi (External Software): Quadrigraphs are not
8677 processed correctly in AS_HELP_STRING; avoid this in the examples.
8678 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8679 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8680 comment and reduce m4_default([foo], []) to [foo].
8681 (m4_strip): Update the explanation.
8683 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8685 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

8687 Problem reported by Jennis Pruett.
8688 * lib/autoconf/functions.m4
8689 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

8739 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8740 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8741 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8743 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8745 * NEWS: The configure command now warns you if you attempt to use
8746 a directory whose name contains a special character like space,
8748 * doc/autoconf.texi (Installation Directory Variables): Allow
8749 "," in file names. Do not use \@; it's not a portable regexp.

8761 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8762 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8763 ac_pwd, and quote srcdir.
8764 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8766 * doc/autoconf.texi: Fix some systematic formatting problems.
8767 ".)" needs a following @: if not at the end of a sentence, and
8768 similarly for "!)". "etc." should be preceded by a comma.
8769 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8771 2005-03-22 Bruno Haible <bruno@clisp.org>
8773 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8774 argument is often called 'build-aux'.
8776 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8778 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8779 macro AC_TRY_LINK is obsolete.
8780 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8783 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8785 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8786 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8787 from a Common Lisp's `cl'.
8788 (AC_PROG_CXX): Behave according to the documentation: don't
8789 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8790 make the variable CCC precious; use `cl.exe', not `cl'.
8792 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8793 Alexandre Duret-Lutz <adl@gnu.org>
8795 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8796 /dev/null, as "configure" shouldn't read stdin, and this insulates
8797 us from problems (e.g., when testing for "cl"). Also, do this
8798 redirection before invoking "hostname" or "uname", and keep the
8799 original input stream available via...
8800 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8801 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

8813 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8814 newline if neither \c nor -n work, as that would output two
8815 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8817 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8819 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8820 This causes that any required macros inside will get before the if.
8821 * doc/autoconf.texi (autom4te.cache): A typo.
8823 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8825 Undo previous change, except keep the change to
8826 lib/autoconf/programs.m4 that replaced grep with shell
8827 pattern-matching. This is because net-snmp configure reads stdin.
8828 Reported by Noah Misch.
8830 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8832 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8833 from /dev/null, as "configure" shouldn't read stdin, and this
8834 insulates us from problems (e.g., when testing for "cl").
8835 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8836 before invoking "hostname" or "uname".
8837 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8838 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8839 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8840 "</dev/null" since it's now done at the top of 'configure'.
8841 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8842 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8843 Also, replace grep with shell pattern-matching, to save a process.
8845 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8847 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8848 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8849 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8852 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8854 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8855 grep -q isn't portable. Improve grep -s explanation.
8856 Problem reported by Dan Manthey.
8858 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8860 * doc/autoconf.texi (Special Shell Variables): Clarify
8861 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8863 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8865 * doc/autoconf.texi: Use @acronym for DJGPP.
8866 Fix some @code's that should have been @env's, and vice versa.
8867 Sort environment variable names.
8868 Mention that shells no longer inherit IFS.
8869 Don't recommend PATH_SEPARATOR=';' so strongly.
8870 Mention that $RANDOM might expand to the empty string.
8871 "symlink" and "soft link" -> "symbolic link".
8872 Improve mktemp description (reported by Bruno Haible).
8874 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8876 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8877 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8879 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):

8886 * tests/local.at (AT_CMP): Use diff directly on input files rather
8889 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in

8893 and Paul Eggert <eggert@cs.ucla.edu>

8905 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8906 (Standard regular expressions): New test.
8907 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8908 excess test name quoting.
8909 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass

8912 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not

8948 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

8951 2047-byte limit on line length of portable text files.
8952 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):

9011 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9012 Update the long comment explaining it.
9014 m4_require no longer writes an ``is required by'' line to the
9015 execution stack. It contains only one bit of non-redundant
9016 information: that the macro was required, not called. And even
9017 this bit is useless in most situations: have you ever met a macro
9018 which both calls and requires the same macro?
9020 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9021 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9023 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9024 (m4_expansion_stack_pop): Remove the misplaced comment.
9025 (m4_require): Don't put the ``is required by'' line to the
9026 execution stack; slightly improve the out-of-a-defun error message.
9027 (_m4_divert_grow): New macro, counter for the temporary diversions.
9028 (_m4_require_call): Use it.
9029 * tests/m4sugar.at (m4_require): Expect output without the

9440 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

9520 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
9521 limitations. Reorder paragraphs for clarity.
9523 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
9525 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9526 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9527 variants", "Unix", and some related minor wording fixups.
9529 (Shellology, Special Shell Variables): Document that the Zsh
9530 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9531 to Alexandre Duret-Lutz for this info.
9533 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>
9535 * doc/autoconf.texi (One-Shot Macros): New node.
9537 2004-09-28 Paul Eggert <eggert@cs.ucla.edu>
9539 * doc/autoconf.texi (Function Portability): Fix misdescription
9540 of putenv. Problem reported by Michael Wardle.
9542 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
9544 * doc/autoconf.texi (auindex): New macro.
9545 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9546 Problem reported by Stepan Kasal.

9550 Fix problems reported by Andreas Buening in:
9551 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
9552 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9554 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9555 readable; it's not true in OS/2-emx.
9557 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9559 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9560 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9561 (trivial change). Problem and patch reported by Andrew Church in:
9562 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9564 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
9566 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
9567 three args in examples. Problem reported by Frederik Fouvry in:

9585 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
9589 * README: Add advice about m4 1.4.2.
9591 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9592 texinfo.tex for now (done by hand now).
9593 * Makefile.maint (wget_files, cvs_files):
9594 Remove ansi2knr.c; nobody uses it.
9595 (ansi2knr.c-url_prefix): Remove.
9596 (cvs-update): Fix test for failure. I don't know why it ever
9599 * doc/autoconf.texi: Update URLs, some of which went stale.
9600 Use @uref rather than @href.
9602 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9603 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9605 * config/config.guess, config/config.sub, config/elisp-comp,
9606 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9607 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9609 * NEWS, TODO, configure.ac, bin/autoscan.in,
9610 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
9611 doc/install.texi, lib/Autom4te/Configure_ac.pm,

9615 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9616 tests/tools.at, tests/torture.at:
9617 Use "file name" rather than "filename" or "path",
9618 to be consistent with the terminology of the GNU coding standards.
9620 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9622 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9623 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9624 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9625 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9627 More fixes to support spaces in the name of the build directory.
9628 This isn't a complete fix but it's an improvement.
9630 * bin/autoconf.as (autom4te_options): New var.
9631 Use it instead of appending to AUTOM4TE, so that we can allow
9632 spaces in the build directory's absolute name.
9633 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9634 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9635 AT_CHECK_NOESCAPE): Likewise.
9636 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9637 main program): Likewise.
9639 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9641 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

9647 * doc/autoconf.texi (Function Portability): Document isinf and
9648 and isnan. From a suggestion by Kevin Ryde.
9650 * lib/Autom4te/General.pm (END): Return correct exit status even
9651 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9653 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9655 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9656 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9657 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9659 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9661 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9662 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9663 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9664 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9665 * lib/autom4te.in (Automake-preselections): Preselect
9666 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9668 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9670 * lib/autom4te.in (Automake-preselections): Preselect
9671 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9674 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9676 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9678 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9679 Document problem with "`""`" in pdksh POSIX mode.
9681 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9683 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9684 with pdksh, too. Problem reported by Patrick Welche via
9686 * doc/autoconf.texi (Shellology): Note that set -o posix is
9687 useful for pkdsh, too.
9689 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9691 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9692 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9693 Don't fail if ENV or BASH_ENV is readonly.
9694 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9695 etc. are read only. Problem reported by Ludovic Courtes.
9697 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9699 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9700 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9703 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9705 * doc/autoconf.texi (File System Conventions): Warn about
9706 names like "aux". Problem reported by Eric Blake.
9708 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9709 by zero instead of array size, so that we can use any arithmetic
9710 constant expression (instead of requiring an integer constant
9711 expression). This allows us to test expressions like DBL_MAX <
9712 LDBL_MAX, which didn't conform to the C standard using the old
9714 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9715 now that we can do floating-point tests at compile time.
9717 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9719 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9720 and LDBL_EPSILON, as the resulting expression isn't an
9721 integer constant expression and violates the C standard.
9722 Problem reported by Nelson H. F. Beebe. Also, check
9723 for "L" suffix, and check that long double doesn't have
9724 worse range or precision than double, that mixed-mode
9725 arithmetic doesn't generate a diagnostic, that double
9726 constants fit in long double.
9728 2004-06-03 Kevin Ryde <user42@zip.com.au>
9730 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9731 malloc(0) and realloc(NULL,size).
9733 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9736 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9738 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9739 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9742 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9744 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9745 can be rewritten using if-then-else. Suggested by Bruno Haible.
9747 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9749 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9750 Problem reported by Stepan Kasal.
9752 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9754 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9755 change). Patch reported by Ralf Wildenhues in
9756 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9758 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9759 function F exists if the compiler and linker let you compile an
9760 expression like (F != 0). Recent versions of GCC optimize away
9761 the reference to F in that case, since every function address must
9762 be nonzero, so the link succeeds even if F does not exist.
9763 Problem reported by Manu in
9764 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9766 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9767 "Unix". Many uses changed.
9768 (Limitations of Builtins): Explain better why the ! command isn't
9771 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9773 * lib/autom4te.in (Automake-preselections): Preselect
9774 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9776 2004-05-19 Kevin Ryde <user42@zip.com.au>
9778 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9779 referencing AC_FUNC_STRERROR_R.
9781 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9782 note pessimistic assumption when cross compiling.
9784 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9786 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9787 (until 2004) invoked subcommands with sh -e, contra POSIX.
9788 Reported by Kevin Ryde.
9790 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9792 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9793 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9794 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9795 `test -f " /usr/bin/grep"', which _always_ failed.
9796 (AC_PROG_SED): Ditto bogus PATH fix.
9797 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9798 requires that grep correctly supports _multiple_ `-e' options, rather
9799 than stating only that grep should accept `-e'.
9801 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9803 Port to C99, which requires that 'exit' be declared.
9805 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9806 to ensure that stdlib.h is included.
9807 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9808 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9809 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9810 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9811 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9812 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9813 when using 'exit' in a test; C99 requires that 'exit' be declared.
9815 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9817 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9818 now prefers 'grep' implementations that accept -e.
9819 (Limitations of Usual Tools): Describe problems of traditional
9820 egrep and fgrep with long input lines, and of traditional grep
9822 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9823 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9824 All callers changed. Append /usr/xpg4/bin to the PATH, for
9826 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9827 the user with complaints about multiple -e options.
9828 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9829 Define it with AC_PROG_GREP.
9830 * configure.ac (AC_PROG_GREP): Add.
9831 * lib/freeze.mk (GREP): New macro.
9833 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9835 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9836 a possible candidate only after all others fail, rather than
9837 consulting it first. This improves backward compatibility by
9838 better reflecting the way shell selection occurred in previous
9839 versions of Autoconf, and should help to avoid triggering latent
9840 problems in other packages, such as the one in Automake where zsh
9841 is not handled robustly:
9842 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9843 Although it is not Autoconf's responsibility to work around
9844 problems in Automake, it nevertheless makes sense to avoid
9845 introducing unnecessary incompatibilites.
9847 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9848 Gary V. Vaughan <gary@gnu.org>
9850 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9851 how deeply nested we are when a suitable tool is found, set the
9852 ac_path_TOOL_found flag.
9853 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9854 nested we are in this macro. Break out of all 3 nested loops if
9855 ac_path_TOOL_found is set.
9857 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9859 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9860 of the _AS_PATH_WALK loop too if GNU flavor is found.
9862 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9864 * doc/autoconf.texi (Limitations of Make): Update documentation
9865 for `$<'. New entry `Long lines', based on a report from Simon
9866 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9867 paragraph about DJGPP, based on a mail from Richard Dawe.
9869 2004-04-20 Paul Eggert <eggert@twinsun.com>
9871 * tests/c.at (C keywords): Don't assume that GCC supports
9872 "restrict" and "inline", as sufficiently-old GCC versions do not
9873 (also, GCC configured to be in pedantic C89 mode does not).
9874 Problem reported by Sumit Pandya in:
9875 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9877 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9878 consider -g to work if it generates warnings when plain compiles
9879 don't. Problem reported by Braden McDaniel in:
9880 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9882 * doc/autoconf.texi (Slashes): New section, to document a problem
9883 reported by Jim Meyering in:
9884 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9886 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9887 linker output files before linking, to work around IRIX 6 linker bug.
9888 Problem reported by Rainer Orth in:
9889 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9891 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9893 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9894 best tool so far counter rely on the tool path variable name to
9895 avoid checks for one tool being affected by the results of running
9896 the length check on a previous tool.
9898 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9899 match expression argument, as different greps have different
9900 regular expression flavours.
9901 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9903 (AC_PROG_EGREP): Pass 'EGREP$'.
9904 (AC_PROG_GREP): Pass 'GREP$'.
9906 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9908 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9909 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9911 2004-03-29 Paul Eggert <eggert@twinsun.com>
9913 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9914 Types, Specific Compiler Characteristics, System Services,
9915 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9916 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9917 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9918 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9920 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9921 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9922 AC_TYPE_OFF_T): Likewise.
9923 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):

9929 2004-03-28 Paul Eggert <eggert@twinsun.com>
9931 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9932 now defines HAVE_DECL_TZNAME if it is declared, when
9933 HAVE_STRUCT_TM_TM_ZONE is not defined.
9934 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9935 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

9940 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9941 superfluous backslashing of quotes (") in sed expressions;
9942 thanks to Paul Eggert.
9944 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9946 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9947 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9948 H. F. Beebe for the bug report.
9950 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9952 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9953 quoted -cmdline argument in Portland Group compiler (bug
9954 reported by Jeffrey J. Barteet).
9956 2004-03-25 Kevin Ryde <user42@zip.com.au>
9958 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9959 (Run Time): ... here, where it's now mentioned.

10004 * bin/Makefile.am (edit): Don't use $< in a context where
10005 POSIX doesn't require support for it. Use $@.in instead.

10023 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10024 problem on QNX reported by Stephen Rasku in
10025 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
10027 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

10036 AC_SUBST provides no portable way to escape literal newlines.
10038 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10039 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10040 Darwin uses -lcrt2.o and there's little point to cataloging all
10041 the system variants. Partial fix reported by Andreas Waechter in:

10067 Paul Eggert <eggert@twinsun.com>
10069 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
10070 (AS_INIT): Output shell initialization there. Removed optional
10071 parameter. Expand _AS_SHELL_FN_SPY.

10084 trigger the bash bug anymore.
10085 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10086 use AS_INIT_WITH_SHELL_FN.
10087 * bin/autoconf.in, tests/wrapper.in: Regenerated.

10117 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

10119 the 2003-05-22 change, which removed the older years from the list.
10120 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

10128 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

10131 egrep and fgrep respectively if $GREP -E/-F don't work.
10132 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10133 _AC_PROG_GREP, and AC_PROG_SED.
10134 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10135 longest input length accepted by a command.

10164 2004-01-26 Paul Eggert <eggert@twinsun.com>
10166 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10167 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10168 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10169 not <inttypes.h>. Problem reported by Tim Mooney in
10170 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10171 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10174 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10175 otherwise "make check" fails because it forbids cmp (I guess
10176 because cmp treats files as binary on DOS-like systems).
10178 * tests/mktests.sh: Update copyright date to 2004, since some tests
10179 have changed in 2004.
10181 2004-01-23 Gary V. Vaughan <gary@gnu.org>

10184 non-truncating sed or gsed program in PATH.

10189 2004-01-15 Paul Eggert <eggert@twinsun.com>
10191 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10192 -std1 disables some useful extensions on Tru64. Problem reported
10193 by N. Lichtmaier in
10194 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10196 2004-01-14 Paul Eggert <eggert@twinsun.com>
10198 * doc/autoconf.texi (Programming in M4sh): Document that
10199 AS_MKDIR_P succeeds if the destination is a symbolic link
10200 to an existing directory.
10201 (Limitations of Usual Tools): Note that mkdir -p might not
10202 succeed on symlinks to directories.
10204 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10206 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10207 * bin/autoheader.in: Grammar fix in message.
10208 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10209 Test for dir before calling mkdir -p. (trivial changes)

10216 2004-01-10 Jim Meyering <jim@meyering.net>
10218 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10220 2004-01-09 Paul Eggert <eggert@twinsun.com>
10222 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10223 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10224 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10225 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10226 AC_COMPILE_IFELSE, since we now assume our caller invokes
10227 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10228 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10229 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10230 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10232 2004-01-07 Paul Eggert <eggert@twinsun.com>
10234 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10235 `"'...'"`, as it's confusing (and I suspect it may not work on
10236 some platforms). The code was incorrect anyway, as it assumed
10237 that \$ evaluated to itself in that context. Reported by
10238 Alexandre Duret-Lutz.
10240 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10242 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10243 and _LT_AC_TAGCONFIG.

10270 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10271 Use "rm -f" to remove conftest.sed, not plain "rm".
10272 Bug reported by David Relson in
10273 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10275 * Makefile.am (autom4te-update):
10276 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

10293 -c -o might not work. From a suggestion by Kevin Ryde.
10294 (C Compiler, Generating Sources, Limitations
10295 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10296 Don't put '-o' after non-options, as POSIX doesn't allow this.
10297 Mention that cc's name might be gcc or c89 or whatever.
10299 2004-01-04 Kevin Ryde <user42@zip.com.au>
10301 * doc/autoconf.texi: Add various further index entries.

10310 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10311 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

10313 explanation clearer.

10324 * tests/atlocal.in: Store the result here.

10329 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10330 * tests/tools.at (Syntax of the shell scripts): Simplify

10405 the expanded body, consistently with other macros such as AC_USG.
10407 2003-11-17 Paul Eggert <eggert@twinsun.com>

10598 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

10623 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10624 cache variable instead of $G77 to decide whether to include -O2,
10625 since $G77 is specific to Fortran 77.

10629 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10630 free" flag. Re-order flags tested into rough order of popularity.
10632 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10634 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10635 arguments so that it can be used with syntax identical to
10636 AC_PROG_F77, and so that we can more easily decide to
10637 remove/deprecate the DIALECT optional argument in the future if it
10638 proves troublesome.
10639 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10640 non-freeform-supporting compilers. Document freeform flags.
10642 2003-10-03 Akim Demaille <akim@epita.fr>

10705 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10706 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

10711 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10712 directory for AC_CONFIG_COMMANDS' first argument exists.
10713 This makes valid the invocation of _AC_SRCPATH that follows.
10714 Reported by Eric Sunshine.

10738 The test suite are sometimes assigning timings incorrectly.
10739 Reported by Henk Krus.
10740 Diagnosed by Nicolas Joly.
10742 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10744 Instead of making AT_help a sequence of assignments to grow
10745 $at_help_all, just make AT_help_all be the growing contents of
10746 $at_help_all, and make a single assignment in...
10748 (at_times_skip): Flip the meaning and rename as...
10749 (at_times_p): this.
10750 (AT_INIT): When summarizing the test that ran, remove

10760 (ifnames): chmod -w.
10761 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10762 executables, not bin/ executables! Otherwise all the magic needed
10763 to find non installed files is turned off. This caused a failure
10764 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10765 as found in its environment (sent by tests/autoreconf): pointing
10766 to bin/autom4te that could not find its files.
10767 * tests/mktests.sh: Force the replacement of generated files, for
10768 the sake of "mv" program that are interactive when overwriting a

10821 and AC_FC_FREEFORM.

10863 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10865 Add support for newer Fortran dialects. The F77 interface is
10866 unchanged, and continues to support Fortran 77. New FC macros
10867 correspond to all the old F77 macros, with output variables FC,
10868 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10869 available dialect, but older dialects can be specified. There are
10870 new macros AC_FC_SRCEXT to set the source extension, and
10871 AC_FC_FREEFORM to accept free-form source files.
10873 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

10966 Output stack traces in warnings.
10968 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10969 Replace the former...
10970 (m4_warn): Pass the call stack to _m4_warn.
10971 * bin/autom4te.in: Adjust to output the call stack.
10972 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10974 2003-08-22 Akim Demaille <akim@epita.fr>

10981 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10982 (&verbose): Remove.

10985 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10986 * bin/autoupdate.in: Adjust.
10987 Use &verb, not &verbose.

10997 2003-08-21 Akim Demaille <akim@epita.fr>
10999 First stab at preserving warnings between calls to autom4te,
11000 including when the cache is used.
11002 There are still several issues: (i) there are too many runs of m4
11003 (one for include, one for warnings, and some more), (ii) warnings
11004 spreading on several lines are not handled gracefully, (iii) the
11005 code meant to have the call stack display for errors does not work
11006 (its handling should move from m4 to autom4te).
11008 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11010 (@preselect): Add m4_warn.
11011 ($exit_status): Remove, use $exit_code.
11012 ($help): Use Autom4te::ChannelDefs::usage.
11013 (&handle_m4): No longer define the m4_warnings.
11014 At each run, extract and report the warnings.
11015 Always cache the result, including if the exit status is on
11016 failure, since if nothing changes, we should result in the same
11017 failure, hence we can use the cache.
11018 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11019 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11021 (m4_warn): Redefine as a do-nothing: it is its invocation that
11022 matters, as warnings are now reported via traces.
11023 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11024 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11025 the latter reveals calls to the former.
11029 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

11051 (&catfile): Remove.
11052 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
11053 * bin/autoscan.in: Adjust.
11055 2003-08-20 Akim Demaille <akim@epita.fr>

11058 Reported by Alexandre Duret-Lutz.
11060 2003-08-20 Akim Demaille <akim@epita.fr>
11062 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11063 * bin/autom4te: Adjust.
11064 In particular, be Autoconf tools are really silent when properly
11065 working, bind the verbosity of the 'note' channel to $verbose.
11066 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11067 (&xsystem, &contents): Remove, since they are exported by...
11068 * lib/Autom4te/FileUtils.pm: this.

11071 * lib/Autom4te/FileUtils.pm: here.

11188 2003-06-23 Akim Demaille <akim@epita.fr>
11190 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11191 not all of them. This fixes 1. the fact that when testing
11192 Autoconf there are many many config.log, 2. the incorrect use of
11193 top_srcdir to find config.log.
11194 Don't mix the detailed output of failed test with the summary of
11195 failures. Rather, append detailed log afterwards.
11197 2003-06-23 Akim Demaille <akim@epita.fr>
11199 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

11282 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11284 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11285 Do not call `_exit()', simply modify `$?'.
11286 (xsystem): Reset $! before running system, and check it afterward.
11287 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11288 63 for version mismatches.
11290 2003-05-23 Akim Demaille <akim@epita.fr>
11292 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of

11314 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11315 Remove `#include <stdlib.h>' from the list; we should never
11316 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11317 resulting namespace pollution would cause other tests to fail.
11318 Configure scripts run with some older versions of g++ and HP's
11319 aCC would fail due to such an #include. Problems reported by
11320 Matthew Mueller in <http://bugs.debian.org/120704> and by
11322 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11323 In the test, use the test declaration before including <stdlib.h>,
11324 as that's closer to how it'll be used.

11328 * doc/autoconf.texi (Header Portability): ucred.h.
11331 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11333 Overhaul Autotest's logging: generate separate log files
11334 in testsuite.dir/NNN/testsuite.log, and append them to
11335 testsuite.log instead of re-running the test verbosely.
11337 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11338 file descriptor, write 0 to at_status_file instead of setting
11339 at_status=0, initialize some new variables (at_status_file,
11340 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11341 to rerun the tests, instead append the at_group_log to the
11342 at_suite_log when a test fails.
11343 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11344 with the AS_MESSAGE_LOG_FD redirected to stdout.
11345 (AT_CLEANUP): save the output status in $at_status_file
11346 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11347 its original place.
11348 (AT_CHECK): since tests are run with a redirected stdout,
11349 and used to be re-run in verbose mode, turn some $at_verbose
11350 into echo, and don't redirect the output of testing stdout
11353 * lib/autotest/autoconf.texi (testsuite Scripts): Update

11474 2003-05-06 Akim Demaille <akim@epita.fr>
11476 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11477 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11478 by aclocal.m4 is changed it might require the importing of another
11479 m4 extension file, i.e., aclocal must be run.

11482 (&parse_args): Use --force with aclocal if required and supported.

11496 2003-04-29 Derek Price <derek@ximbiot.com>
11498 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11499 seperator with m4_append_uniq(). It doesn't work.
11500 (AT_CLEANUP): Add `;' to end of at_help_all.
11501 (AT_INIT): Allow --keywords to be specified more than once. When
11502 grepping $at_help_all for keywords, use the field and keyword

11582 * tests/torture.at (Configuring subdirectories): Require aclocal
11583 1.4, otherwise the test fails, as it does support configure.ac.

11672 * bin/ifnames.in: Add final newline to help and version messages.
11674 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
11675 to cope with DOS-style absolute paths, when constructing
11678 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11679 When constructing paths with IFS=:, quote the path. If we're
11680 constructing a DOS-style absolute path, we don't want to split it
11683 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11686 2003-02-25 Pavel Roskin <proski@gnu.org>

11698 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,

11703 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11704 format starting with "-".
11706 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11708 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11709 is not portable inside Makefile.
11711 2003-02-20 Akim Demaille <akim@epita.fr>
11713 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11714 compiler says yeah, but preproc says nope, compiler is right.
11715 Conversely, prompt the reader to send a bug report to the
11716 maintainers of the package, not of Autoconf.

11720 * bin/autoreconf.in (autoreconf_current_directory): Properly
11721 handle an empty aclocal.m4.

11726 $ac_prefix_program.
11729 2002-12-23 Paul Eggert <eggert@twinsun.com>
11731 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11732 innocuous variant befor including <limits.h> or <assert.h>. This
11733 works around a bug reported by Albert Chin: HP-UX 11i
11734 (and earlier versions) have a <limits.h> that declares
11735 gettimeofday and many other functions.
11737 2002-12-03 Paul Eggert <eggert@twinsun.com>
11741 * NEWS, configure.ac: Update version.
11743 * doc/fdl.texi: Upgrade to FDL version 1.2.
11745 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11746 nontrivially in main's body, so that f's external declaration is
11747 not optimized away in AIX. This should fix the bug reported by
11749 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11751 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11752 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11753 defined, to support freestanding compilers. This should fix the
11754 bug reported by Momchil Velkov in
11755 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11757 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11758 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11769 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11770 \(.*\) match is too long and there is something more to be checked.
11771 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

11789 Update from masters.
11791 2002-11-14 Akim Demaille <akim@epita.fr>
11793 * Makefile.maint: Sync with Bison, i.e.:
11794 (po-check): Scan .l and .y files instead of the
11795 .c and the .h files that they generate. This fixes the bug
11796 reported by Tim Van Holder in:
11797 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11798 Look for N_ as well as for _. Try to avoid matching #define for
11802 2002-11-14 Akim Demaille <akim@epita.fr>
11804 * doc/autoconf.texi (C Compiler): Compiling several files at once.

11807 2002-11-14 Akim Demaille <akim@epita.fr>
11809 * doc/autoconf.texi (C Compiler): Solitary backslashes.
11810 From Paul Eggert and Albert Chin-A-Young.
11812 2002-11-14 Kevin Ryde <user42@zip.com.au>
11814 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11815 than assigning in main, to avoid HP cc +O3 optimizing it away.
11817 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11819 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11820 option. Process --recheck after parsing all options. Pass -q
11821 option to configure on --recheck.
11822 (AC_OUTPUT): Pass -q from configure to config.status.
11823 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11824 arguments to record.
11825 * doc/autoconf.texi (config.status Invocation): Document
11826 config.status -q option.
11828 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11830 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11831 Makefile.in if Makefile.am exists.
11832 (output): Strip `.am' from Makefiles. Don't
11833 output AC_CONFIG_FILES if no Makefiles were found.
11835 2002-11-07 Akim Demaille <akim@epita.fr>
11837 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
11838 (local_updates): New.
11839 * Makefile.maint: Update, from CVS Bison.
11840 (local_updates): New.
11842 2002-11-06 Akim Demaille <akim@epita.fr>
11844 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11845 declaration in extern "C" too.
11846 Reported by Roberto Bagnara.
11848 2002-11-06 Akim Demaille <akim@epita.fr>
11850 * tests/torture.at (Configuring subdirectories): Don't use grep
11852 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
11853 Reported by Ezra Peisach.
11855 2002-11-05 Akim Demaille <akim@epita.fr>
11857 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11859 We _have_ to stop using the old compatibility scheme that tried to
11860 avoid useless backslashes because Libtool 1.4.3 contains a
11861 AC_DEFINE([error_t], [int],
11862 [Define to a type to use for \`error_t' if it is not
11863 otherwise available.])
11864 We _have_ to quote the single quote and backslashes with \. The
11865 old compatibility scheme saw that ` was backslashed, and therefore
11866 did not quote the single quote. Hence before this patch, Autoconf
11867 was not compatible with Libtool.
11869 2002-11-04 Paul Eggert <eggert@twinsun.com>
11871 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

11876 2002-11-04 Akim Demaille <akim@epita.fr>

12258 Reported by Alexandre Duret-Lutz.
12260 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12280 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12281 if some file was changed instead of `print'.
12282 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

12317 From Sam Varshavchik.
12319 2002-10-08 Akim Demaille <akim@epita.fr>
12321 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12322 aclocal invocation, as Gettext macros might not be visible to
12324 Instead of blindly running autopoint, scan configure.ac (not the
12325 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12326 Reported by Paul D. Smith.
12328 2002-10-08 Paul Eggert <eggert@twinsun.com>

12358 * tests/torture.at (Configuring subdirectories): Be robust to

12360 the two last configure runs, using two different sets of
12361 arguments, trigger a legitimate error.

12396 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12397 (.m4.m4f): Don't pass --prepend-include, since that's done by
12398 tests/autom4te itself.
12399 * lib/autoscan/Makefile.am: Include freeze.mk.
12400 (autoscan.list): New target --this file is no longer a source.
12401 (autoscan.pre): New file.
12403 2002-09-28 Akim Demaille <akim@epita.fr>
12405 * bin/autoscan.in (@kinds): Make them singular.
12407 (&init_tables): When --debug, report the list of rules to ease
12408 tracking changes in autoscan.list.
12409 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12411 2002-09-28 Akim Demaille <akim@epita.fr>
12413 * lib/autoscan/functions, lib/autoscan/headers,

12417 * bin/autoscan.in (&init_tables): Adjust.
12419 2002-09-28 Akim Demaille <akim@epita.fr>
12421 * lib/autoscan/functions, lib/autoscan/headers,
12422 * lib/autoscan/identifiers, lib/autoscan/makevars,
12423 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12424 `functions' line is now prefixed with `function:'.
12425 * bin/autoscan.in (&init_tables): Adjust.
12427 2002-09-28 Akim Demaille <akim@epita.fr>
12429 From now on, autoscan files must always map a macro name to a
12430 word: there is no `default' macro for autoscan.
12432 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12434 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12437 2002-09-28 Akim Demaille <akim@epita.fr>
12439 * bin/autoscan.in (%c_keywords): Remove.
12440 (&used): Keep only track of the words we might be interested in.
12441 (&output_kind): It is no longer needed to look for non active
12444 2002-09-27 Akim Demaille <akim@epita.fr>

12455 Thanks to Bill Moseley and Paul Eggert.
12456 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12457 the tmpdir must be created.
12458 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12459 dir be in the build tree, instead of $TMPDIR.
12461 2002-09-27 Akim Demaille <akim@epita.fr>
12463 * bin/autoscan.in: Improve the comments.
12464 (&parse_args): Drop obsolete undocumented options.

12472 Reported by Ralf Corsepius.
12473 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12475 2002-09-26 Akim Demaille <akim@epita.fr>
12477 Single suffix rules and seperated dependencies are not portable.
12479 * doc/autoconf.texi (Installation Directory Variables): Update.
12480 (Limitations of Make): Some about `Single Suffix Rules and
12481 Separated Dependencies'.
12482 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12483 (ifnames, autoscan, autom4te): Un-factor into several rules.
12485 2002-09-25 Paul Eggert <eggert@twinsun.com>
12487 * BUGS (Interoperability bugs): New section. Mention libtool
12488 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12490 2002-09-24 Paul Eggert <eggert@twinsun.com>
12492 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12493 make handles suffix-rules differently from GNU make.
12495 * bin/Makefile.am (SUFFIXES, .in): Remove.
12496 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12497 Move the body of the old .in rule here.
12499 2002-09-16 Akim Demaille <akim@epita.fr>
12501 i960 compilers create `b.out' files by default.
12502 Reported by Ralf Corsepius.
12504 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12505 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12507 2002-09-13 Paul Eggert <eggert@twinsun.com>
12509 * doc/autoconf.texi (Particular Headers): Remove obsolete
12510 reference to `struct timezone' in the description of
12513 2002-09-13 Akim Demaille <akim@epita.fr>
12517 * config/config.sub, config/config.guess: Update.
12518 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12519 * Makefile.am: Adjust.
12521 2002-09-13 Akim Demaille <akim@epita.fr>
12523 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12524 reading config.log when the compiler is rejected.
12525 Suggested by Guido Draheim.
12527 2002-09-13 Akim Demaille <akim@epita.fr>
12529 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12530 (chdir_init) might hang when stat'ing mounted directories.
12531 Reported by Vance Shipley.
12533 2002-09-12 Akim Demaille <akim@epita.fr>
12535 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12538 2002-09-12 Akim Demaille <akim@epita.fr>
12540 * doc/autoconf.texi (Defining Symbols): Present two different
12541 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12542 difference between 1 argument calls, and 2-3 argument calls.
12544 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12546 * doc/autoconf.texi: Review grammar and punctuation.
12548 2002-09-11 Paul Eggert <eggert@twinsun.com>
12550 * doc/autoconf.texi: Fix minor formatting, spelling, and
12552 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12553 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12556 2002-09-11 Akim Demaille <akim@epita.fr>
12558 * doc/autoconf.texi (Questions): Rename as...
12560 (Defining Directories): New.
12562 2002-09-09 Akim Demaille <akim@epita.fr>
12564 * doc/autoconf.texi (Making testsuite Scripts): Update.
12565 Suggested by Nishio Futoshi.
12567 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12569 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12570 plain `@' is wanted.
12572 2002-09-09 Akim Demaille <akim@epita.fr>
12574 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12575 `duplicates', since the algorithm was too naive and could keep
12576 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12577 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12578 Reported by Ralf Corsepius.
12579 * tests/torture.at (Configuring subdirectories): Exercise these
12582 2002-09-09 Akim Demaille <akim@epita.fr>
12584 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12585 looking for a replacement file.
12586 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12587 directory is relative.
12588 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12589 directory definition.
12590 Reported by Andreas Schwab and Jim Meyering.
12592 2002-09-06 Akim Demaille <akim@epita.fr>
12594 * doc/autoconf.texi (Setting Output Variables): Clarify what
12595 precious variables are.
12596 Suggested by Pontus Skoeld.
12598 2002-09-05 Akim Demaille <akim@epita.fr>
12600 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12601 (ifnames, autoscan, autom4te): Since we don't only depend on
12602 configure.ac variables (such as VERSION etc.), but also on prefix
12603 and so forth, depend on Makefile, not configure.ac.
12604 Reported by Alexandre Duret-Lutz.
12605 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12607 2002-09-05 Kevin Ryde <user42@zip.com.au>
12609 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12610 doesn't seem to be confined to ia64, just say "some versions".
12612 2002-09-04 Akim Demaille <akim@epita.fr>
12614 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12616 * Makefile.am (maintainer-clean-local): Remove.
12617 (MAINTAINERCLEANFILES): Remove COPYING.
12619 2002-09-03 Paul Eggert <eggert@twinsun.com>
12621 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12622 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12625 2002-09-03 Akim Demaille <akim@epita.fr>
12627 * configure.ac: Bump to 2.53d.
12628 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12629 as of today, on Automake's team suggestion.
12631 2002-09-03 Akim Demaille <akim@epita.fr>
12635 2002-09-02 Akim Demaille <akim@epita.fr>
12637 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12639 * configure.ac: Disable SITE_MACRO_DIR.
12641 2002-09-02 Jim Meyering <meyering@lucent.com>
12643 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12644 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12645 Also, tweak grammar: s/make sure to/be sure to/.
12647 2002-09-02 Paul Eggert <eggert@twinsun.com>
12649 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12650 directory names are generally preferable to physical names.
12652 2002-09-02 Akim Demaille <akim@epita.fr>
12654 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12655 Reported by Raja R. Harinath.
12656 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12657 * bin/autoupdate.in: Use error instead of die.
12659 2002-09-01 Paul Eggert <eggert@twinsun.com>
12661 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12662 ordinary shell concatenation rather than echo+tr+sed command that
12663 runs afoul of a long-line-related sed bug in Solaris 8.
12665 * bin/autoheader.in (parse_args): --warning -> --warnings.
12667 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12668 stdout, as traditional "ls" does.
12669 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12670 _AC_COMPILER_EXEEXT_O): Likewise.
12671 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12673 * bin/autoconf.as: Add --prepend-include option. This patch was
12674 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12675 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12677 * bin/autoconf.in, configure: Regenerate.
12679 * doc/autoconf.texi (Special Shell Variables): Mention
12680 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12682 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12683 MAILPATH and set PS1, PS2, PS4 to default values, to work
12684 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12685 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12686 the Autoconf documentation specifies; fall back to "unset" only if
12687 this fails. Use a shell for-loop for this rather than an m4 loop,
12688 to shorten the output script.
12690 2002-08-30 Paul Eggert <eggert@twinsun.com>
12692 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12693 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12694 for the CDPATH problem. Document PWD.
12695 (Limitations of Builtins): Document the problem that "cd $foo" and
12696 "ls $foo" may refer to different directories in shells conforming
12697 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12698 example, since the old example is now out of date.
12700 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12701 FOO" and "ls FOO" talk about different directories; this catches
12702 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12705 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12706 of rolling our own unset.
12707 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12708 in practice we needn't worry about CDPATH if unset doesn't work.
12710 * Makefile.in, aclocal.m4, bin/Makefile.in,
12711 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12712 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12713 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12714 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12715 tests/Makefile.in: Regenerate with Automake 1.6.3.
12717 * config/config.guess, config/config.sub, config/mkinstalldirs:
12720 * configure: Regenerate with self.
12722 2002-08-30 Kevin Ryde <user42@zip.com.au>
12724 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12727 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12729 * bin/autom4te.in (Request::load): Correctly test for "do" read
12732 2002-08-29 Akim Demaille <akim@epita.fr>
12734 * lib/Autom4te/General.pm (&xqx): New.
12735 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12736 hand, which is not portable.
12738 * bin/autom4te.in: Use them.
12739 Use &error instead of die.
12740 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12743 2002-08-17 Paul Eggert <eggert@twinsun.com>
12745 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12746 default list of compilers to try, since it was long ago superseded
12747 by the ksh fc builtin. Suggested by Steven G. Johnson.
12749 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12751 * doc/autoconf.texi (Invoking autom4te): End the option table,
12752 fixing a bug introduced by the previous patch.
12753 (Limitations of Make): Add a 'target lookup' subentry in the
12754 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12756 2002-07-29 Mark D. Roth <roth@feep.net>
12758 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12759 options and use $AUTOM4TE_PATH.
12760 * doc/autoconf.texi: Remove documentation of autom4te
12761 --include-envvar and --site-macro-subdir options and document
12762 use of $AUTOM4TE_PATH.
12763 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12764 arguments from each language section.
12766 2002-07-29 Paul Eggert <eggert@twinsun.com>
12768 * doc/install.texi: Include copyright symbol in copyright notice.
12770 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12772 (AM_MAKEINFOFLAGS): New macro.
12773 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12774 * Makefile.am (INSTALL): Use the new macros.
12775 Use -o rather than --output, since "missing" does not grok --output.
12777 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12779 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12780 comments do not always work. Never trust the exit status of
12783 2002-07-24 Kevin Ryde <user42@zip.com.au>
12785 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12786 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12788 2002-07-23 Paul Eggert <eggert@twinsun.com>
12790 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12791 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12792 apparently treats PATH="nonexistent" as if it contained ".".
12793 Bug reported by Stefan `Sec' Zehl.
12795 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12797 * doc/autoconf.texi (Limitations of Make): Mention the special
12798 handling of the obj/ directory by BSD make.
12800 2002-07-20 Kevin Ryde <user42@zip.com.au>
12802 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

12818 2002-07-18 Akim Demaille <akim@epita.fr>
12820 * config/config.guess, config/config.sub: Update.
12822 2002-07-18 Akim Demaille <akim@epita.fr>
12824 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

12831 2002-07-18 Akim Demaille <akim@epita.fr>,
12832 Alexandre Duret-Lutz <duret_g@epita.fr>
12834 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
12835 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
12837 2002-07-17 Russ Allbery <rra@stanford.edu>

12840 description of the tarname default.
12842 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
12844 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12845 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12846 latter was not run.
12848 2002-07-17 Akim Demaille <akim@epita.fr>
12850 * lib/Autom4te/General.pm (find_file): Browse the directories in
12851 the order they are given.
12853 2002-07-17 Akim Demaille <akim@epita.fr>
12855 * tests/wrapsh.as, tests/wrappl.as: Merge into...
12856 * tests/wrapper.as: this.
12857 * tests/Makefile.am, configure.ac: Adjust.
12859 2002-07-17 Mark D. Roth <roth@feep.net>
12861 * configure.ac: Add --enable-site-macro-dir option.
12862 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
12863 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
12864 --site-macro-subdir options.
12865 * bin/autoconf.in: Add --prepend-include option.
12866 * bin/autoheader.in: Add --prepend-include option.

13063 This improves on an earlier suggestion by H. Peter Anvin.
13065 2002-05-16 Paul Eggert <eggert@twinsun.com>
13067 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13068 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13069 Both macros now accept an optional source-dir arg.
13070 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13072 * NEWS: Document this.
13073 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13075 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13076 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13077 not for GNU extensions; this undoes part of the 2000-11-03 change,
13078 reverting to 2.13-compatible behavior.

13086 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13087 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13088 and it causes a 'test' syntax error if it fails.
13089 Bug reported by Stephen Gildea.
13091 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13092 If prototypes are supported, use them to check this at compile-time,
13093 instead of trying to check it at run-time. If we must do a run-time
13094 check, assume that setvbuf is standard when cross-compiling, as
13095 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13096 Bug reported by Paul D. Smith.
13098 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13099 argument specifying location of getloadavg.c. This removes a
13100 FIXME. This idea was taken from Jim Meyering's implementation in
13102 * doc/autoconf.texi (Particular Functions): Document this.
13103 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13104 that's what the code does; this fixes a bug reported by

13109 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13110 autopoint instead of gettextize.
13111 ($uses_alocal): Rename as...
13112 ($uses_aclocal): this.
13113 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13114 Suggested by Bruno Haible.
13116 2002-05-03 Akim Demaille <akim@epita.fr>
13118 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13120 2002-04-29 Paul Eggert <eggert@twinsun.com>
13122 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13123 files to be 1 second older; just set them to be the same time.
13124 Also, sleep 1 second after the first aclocal, to work around
13125 problems with sub-second time stamps on the input files.
13127 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13129 * doc/autoconf.texi: Mention "set -e -x" lossage
13130 under node "Limitations of Builtins".

13136 From Christian Cornelssen.
13138 2002-04-29 Akim Demaille <akim@epita.fr>
13140 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13141 of lack of $LINENO support, then the test will compare the $LINENO
13142 in testsuite vs. the lineno in the test file. This is wrong, of
13144 Be sure to protect it.
13145 Reported by Patrick Welche.
13147 2002-04-25 Akim Demaille <akim@epita.fr>
13149 * doc/autoconf.texi (Obsolete Macros): Typo.
13150 Reported by Vladimir Volovich.
13152 2002-04-25 Akim Demaille <akim@epita.fr>
13154 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13155 than some of the input files, hence, on the second run of aclocal,
13156 if some of its input are younger, make them older.
13157 Suggested by Paul Eggert.
13159 2002-04-25 Akim Demaille <akim@epita.fr>
13161 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

13167 and ac_subst_vars be sh variables containing the list of
13168 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13170 (_AC_INIT_PREPARE): Use them to log them.
13171 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13172 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13173 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13174 _AC_SUBST_FILES and _AC_SUBST_VARS.
13175 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13177 2002-04-24 Akim Demaille <akim@epita.fr>
13179 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13180 autoheader, so that automake does not complain about a missing
13181 config.h.in that was to be created.
13183 2002-04-23 Akim Demaille <akim@epita.fr>

13239 importantly, this makes sure that the copyright notices appear in

13352 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13353 syntax, as it is provided by M4sugar.
13354 * tests/torture.at (Multiple AC_CONFIG_FILES): New.

13370 (_AC_COMPILER_OBJEXT): Use them.
13371 Fixes Debian #138666.
13373 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13375 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13377 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13378 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13379 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

13395 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13396 to avoid versions of HP C which don't allow that.
13398 2002-03-27 Paul Eggert <eggert@twinsun.com>

13412 2002-03-25 Paul Eggert <eggert@twinsun.com>
13414 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13415 as POSIX requires, as it doesn't work with Zsh.
13416 * doc/autoconf.texi (Assignments): Document the problem.
13418 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

13421 about VPATH, overriding of macros in sub-makes, and handling of

13426 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13427 problem with here-document buffer boundaries.
13429 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13430 when reinvoking the shell, to work around problems with installers
13431 who put strange things like "cd" commands in their environments.

13456 (Limitations of Usual Tools): Add mkdir section.
13458 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13459 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13460 back on AS_DIRNAME to compute prefixes otherwise; this is
13461 roughly what mkinstalldirs does. That way, we need not have
13462 our own filename disassembler. The old disassembler did not
13463 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13465 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13466 Create at_test_all by a series of assignments,
13467 not by a single assignment of a long string. The latter causes ksh
13468 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13469 presumably because of a buffer overrun.
13471 2002-03-14 Paul Eggert <eggert@twinsun.com>
13473 * lib/autotest/general.m4 (at_times_skip):
13474 Renamed from at_times. Now a boolean.
13475 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13476 says 'times: not found'.

13480 * bin/autoreconf.in (&study_gettextize): New.
13481 (&autoreconf): Handle newest gettextize.

13505 2002-03-11 Andreas Schwab <schwab@suse.de>

13508 does not do it if --with-lispdir is given.

13519 2002-03-08 Akim Demaille <akim@epita.fr>
13521 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13523 2002-03-08 Akim Demaille <akim@epita.fr>
13525 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13526 aliases the actual variables, and modifications of the former
13529 2002-03-08 Akim Demaille <akim@epita.fr>
13531 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13532 because of C-c: have m4 output in tmp files, then mv them.
13534 2002-03-08 Akim Demaille <akim@epita.fr>

13555 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13556 * lib/autoconf/general.m4 (AC_INIT): More informative error
13557 message for LIBOBJ.
13559 2002-03-04 Akim Demaille <akim@epita.fr>

13564 2002-03-04 Akim Demaille <akim@epita.fr>
13566 * doc/autoconf.texi (Transforming Names): Equality between target
13567 and host is irrelevant.
13568 (Specifying Names, Canonicalizing): Remove all references to the
13569 backward compatibility hooks. Rather, collect them all into...
13570 (Hosts and Cross-Compilation): this new section.
13571 * doc/install.texi (System Type): Ditto.
13572 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13573 that `--host' implies cross-compilation.
13575 2002-03-04 Akim Demaille <akim@epita.fr>
13577 * doc/autoconf.texi (Evaluation Macros): New.
13578 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13580 (_m4_foreach): Define the variant with immediate evaluation so
13581 that it contains exactly the items, not an expression which
13582 evaluation is the current item.
13583 (m4_re_string, m4_re_word): Don't over quote them.
13585 2002-03-04 Akim Demaille <akim@epita.fr>
13587 Instead of having stacking `shift's evaluated at the end, let
13588 `foreach' loops immediately evaluate them.
13590 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13591 $*. This is the n-th time I change my mind, but hopefully this is
13594 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13596 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13597 it was only a hack for m4_text_wrap.
13598 (m4_car2): Remove, replaced by...
13600 (_m4_foreach): Adjust.
13601 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13602 m4_bpatsubst for clarification.

13654 AC_PREFIX_PROGRAM fails with dashed program names
13656 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

13693 2002-02-05 Akim Demaille <akim@epita.fr>
13695 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13718 optional are the sum of the previous files on the command line'.
13719 Also, pass `--reload-state=' on them, so...
13720 (handle_m4): don't.

13722 (M4sh): Rely on M4sugar.

13760 2002-01-28 Akim Demaille <akim@epita.fr>
13762 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13763 AUTOTEST_PATH *after* it was set.
13764 Don't put `.' in the PATH: the user should be precise and `./' if
13765 needed. In addition, given that the test suite does some `cd', if
13766 `.' is in the path, the `tested programs' sections will report
13767 programs found in the test suite's directory, while during the
13768 tests (performed in their own directory), these programs are no
13769 longer visible. In other words, the results is confusing and

13846 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13847 and PACKAGE_BUGREPORT from here...
13848 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the

13866 2001-12-18 Kevin Ryde <user42@zip.com.au>
13868 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13869 sometimes needing writable input.
13871 2001-12-17 Jim Meyering <meyering@lucent.com>
13873 * doc/autoconf.texi (New Macros): Tweak wording.
13875 2001-12-14 Akim Demaille <akim@epita.fr>
13877 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13878 trailing files, don't apply `-rf' to files which might not be
13879 created by configure (core, core.*, and *.core), but just `rm -f'.
13880 Suggested by Jonathan Kamens.
13882 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13884 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13886 2001-12-14 Akim Demaille <akim@epita.fr>
13888 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13890 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13892 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13893 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13894 abs_srcdir, top_srcpath to abs_top_srcdir.
13895 (_AC_OUTPUT_FILES): Adjust.
13896 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13897 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13898 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13900 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13902 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13903 C/Fortran linking on HP/UX, by extracting the Fortran library
13904 search path from the LPATH line in the $F77 -v output.
13906 2001-12-12 Kevin Ryde <user42@zip.com.au>
13908 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13909 forbidden file descriptors table.
13911 2001-11-26 Akim Demaille <akim@epita.fr>
13913 * bin/autoscan.in (%c_keywords): Build it at top level.
13914 Map to 1 in order to simplify its uses.
13916 2001-11-26 Akim Demaille <akim@epita.fr>
13918 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13919 Remove $filepath, useless.
13920 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13921 variables, they are really part of the tokens.
13922 Split the input line on spaces and then look for tokens.
13923 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13924 because of `lex$U.$(OBJEXT)'.
13925 (&scan_files): Use "@list" instead of join.
13926 * doc/Makefile.am (CLEANFILES): Add *.fns.
13928 2001-11-26 Akim Demaille <akim@epita.fr>
13930 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13931 Remove, replaced by...
13932 * tests/wrappl.in: Be common for all the Perl executables.
13933 In particular autoscan and autoheader want -I.
13934 * configure.ac: Adjust.
13935 * lib/autoscan/headers: errno.h is portable.
13937 2001-11-26 Akim Demaille <akim@epita.fr>
13939 * bin/autoscan.in (used): New.
13942 2001-11-26 Akim Demaille <akim@epita.fr>
13944 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13946 (&scan_sh_file): Remove a duplicate pattern.
13947 (&check_configure_ac): Use long options.
13948 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13950 2001-11-26 Akim Demaille <akim@epita.fr>
13952 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13953 Before, having a line containing the opening of a multi line
13954 comment made the whole line be ignored.
13956 2001-11-26 Akim Demaille <akim@epita.fr>
13958 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13959 (testsuite Scripts): Be one of its subsection.
13960 (Autotest Logs): New.
13962 2001-11-26 Akim Demaille <akim@epita.fr>
13964 Test groups are now run two directories deeper.
13966 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13967 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13969 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13970 top_srcdir, builddir and top_builddir.
13971 Use `at_*dir' relatively to the directory containing the
13972 suite, use `*dir' when relatively to the current group dir.
13974 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13976 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13977 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13978 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13981 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13983 * doc/autoconf.texi (Using System Type): Add an example of `case
13984 $host' usage so people quit using `case $target' everywhere.
13986 2001-11-22 Akim Demaille <akim@epita.fr>
13988 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13989 spotted by Jim Meyering.
13991 2001-11-16 Paul Eggert <eggert@twinsun.com>
13993 This patch implements a `long double' suggestion by Oliver Kiddle.
13995 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13996 static, to catch errors if the value isn't known at compile-time
13997 and the compiler supports dynamic arrays. Change its name from
13998 `_array_' to `test_array' to avoid potential name clashes.
13999 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14000 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14001 better than double. Catch a bug in GCC 2.95.2 x86.
14002 * doc/autoconf.texi (C Compiler): Document the above.
14005 2001-11-13 Akim Demaille <akim@epita.fr>
14007 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14009 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14011 2001-11-13 Akim Demaille <akim@epita.fr>
14013 * lib/autotest/general.m4 (AT_INIT): After having run the test
14014 group, go back to the initial directory, not to at_suite_dir.
14016 2001-11-13 Akim Demaille <akim@epita.fr>
14018 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14019 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14020 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14022 (AT_CHECK_CONFIGURE): Use absolute paths.
14023 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14024 The problem is still the old one: there is no means in M4 (that I
14025 know about) to create a defining macro, because there is no means
14026 to create `$1' etc., therefore, the defining macro ``swallows''
14027 all the arguments meant to the defined macro.
14029 2001-11-13 Akim Demaille <akim@epita.fr>
14031 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14032 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14034 * tests/aclocal.m4: Remove, as it is no longer used.
14036 2001-11-13 Akim Demaille <akim@epita.fr>
14038 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14039 variable names when referring to a single test group, or to
14040 `suite' when referring to the whole test suite.
14041 `at_last_test' is removed: m4 compute at_format itself.
14042 (at_stdout, at_stder1, at_stderr): New variables.
14043 (AT_CHECK): Use them.
14045 2001-11-13 Akim Demaille <akim@epita.fr>
14047 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14049 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14050 Do it as soon as a test fails, don't wait till the end of the test
14052 Don't remove $as_me.[0-9]*, since these files no longer exist.
14054 2001-11-13 Akim Demaille <akim@epita.fr>
14056 * tests/tools.at: Use absolute paths, since we are no longer run
14059 2001-11-13 Akim Demaille <akim@epita.fr>
14061 Now that tests are running in their own private dir, there is no
14062 need to list the files to remove at the end of tests groups.
14064 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14065 (AT_data_files, at_data_files): Remove.
14066 (AT_CLEANUP, AT_DATA): Simplify.
14068 Remove the group dir if !debug && !failed.
14069 * tests/atspecific.m4: Adjust.
14071 2001-11-13 Akim Demaille <akim@epita.fr>
14073 Start a new layout for Autotest: `testsuite' creates
14074 `testsuite.dir' in which the at-check-line etc. files are to be
14075 found, and `testsuite.dir/003' where the test group 3 is run.
14077 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14078 at_check_line_file, at_format, at_test_normalized, at_group_dir
14080 Create the directories.
14081 Use absolute paths for at- files.
14082 (AT_CHECK): Adjust.
14084 2001-11-11 Michael Matz <matz@kde.org>
14086 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14088 (m4_car): Properly quote arguments.
14090 2001-11-13 Akim Demaille <akim@epita.fr>
14092 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14093 with stricter rules on LIBOBJS.
14095 2001-11-12 Paul Eggert <eggert@twinsun.com>
14097 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14098 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14101 2001-11-12 Akim Demaille <akim@epita.fr>
14103 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14105 2001-11-12 Akim Demaille <akim@epita.fr>
14107 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14108 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14109 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14110 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14111 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14112 specify to what the macro should be defined (typically to 1).
14114 2001-11-12 Akim Demaille <akim@epita.fr>
14116 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14119 2001-11-12 Akim Demaille <akim@epita.fr>
14121 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14122 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14123 definition used by Automake where LEX is +/- "${missing} lex" and
14124 `missing' itself contains variables.
14126 2001-11-12 Akim Demaille <akim@epita.fr>
14128 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14129 Now that M4sh pushes BODY, the comments were output at the end of
14132 2001-11-08 Akim Demaille <akim@epita.fr>
14134 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14135 that we can trace macros from aclocal.m4.
14136 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14137 obsoleted, and redirect to the former anyway.
14138 Reported by Ralf Corsepius.
14140 2001-11-08 Akim Demaille <akim@epita.fr>
14142 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14143 processed only if present.
14144 * tests/torture.at (Configuring subdirectories): Use autoreconf
14145 instead of successive calls to autoconf.
14146 Add a nonexistent subdirectory to exercise the patch above.
14147 Reported by Ralf Corsepius.
14149 2001-11-08 Kevin Ryde <user42@zip.com.au>
14151 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14152 doesn't accept .S files.
14154 2001-11-07 Akim Demaille <akim@epita.fr>
14156 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14157 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14158 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14159 * bin/autom4te.in (warn_forbidden): New.
14160 (handle_output): Use it.
14161 Read m4_pattern_forbid with messages.
14163 2001-11-05 Akim Demaille <akim@epita.fr>
14165 * bin/autom4te.in (--normalize): Remove.
14166 * lib/autom4te.in: Adjust.
14168 2001-11-05 Akim Demaille <akim@epita.fr>
14170 * tests/Makefile.am (testsuite): Rename this target as...
14171 ($(TESTSUITE)): this.
14174 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14176 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14177 the --prefix option, also remove it's argument.
14179 2001-11-05 Akim Demaille <akim@epita.fr>
14181 * doc/autoconf.texi (testsuite Invocation): Update.
14182 (Writing testsuite.at): Update.
14184 2001-11-03 Akim Demaille <akim@epita.fr>
14186 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14188 2001-11-03 Akim Demaille <akim@epita.fr>
14190 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14191 (&file_name_is_absolute): New, wrappers around routines from
14193 Use and export them.
14194 (&find_configure_ac): Optionally take a directory where to look at.
14195 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14197 Default @ARGV to `.', not find_configure_ac.
14198 (&autoreconf): Argument is a directory.
14199 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14200 * doc/autoconf.texi (autoreconf Invocation): Update.
14202 2001-11-03 Akim Demaille <akim@epita.fr>
14204 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14205 (@export_forward_subs): New.
14206 Add basename, dirname, and fileparse.
14208 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14209 Don't look for aclocal flags if we already know aclocal is not
14211 Move aclocal.m4t only if it exists.
14212 Reported by Ezra Peisach.
14214 2001-11-03 Akim Demaille <akim@epita.fr>
14216 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14217 passed on command line, defaulting to ./configure.ac if present.
14218 (&maybe_autoreconf, File::Find): Remove, unused.
14219 (&autoreconf): If autoconf is not used, don't try to trace.
14221 2001-11-02 Akim Demaille <akim@epita.fr>
14223 * configure.ac: Bump to 2.52g.
14225 2001-11-02 Akim Demaille <akim@epita.fr>
14229 2001-11-02 Akim Demaille <akim@epita.fr>
14231 * config/config.guess, config/config.sub, doc/standards.texi:
14232 * config/lispdir.m4: Update from masters.
14233 * configure.ac: Bump to 2.52f.
14235 2001-11-02 Akim Demaille <akim@epita.fr>
14237 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14238 Don't run aclocal when aclocal.m4 is not from aclocal.
14240 Don't run libtoolize and gettextize if --install is not given.
14242 2001-11-01 Paul Eggert <eggert@twinsun.com>
14244 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14245 be invoked before _AS_LINENO_PREPARE.
14246 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14247 than character ranges.
14249 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14250 invoking AS_BASENAME. Set the locale variables to 'C' if
14251 possible, as POSIX requires this to get the traditional
14253 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14255 2001-10-31 Paul Eggert <eggert@twinsun.com>
14257 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14258 with {}, as that triggers a bug in Bash 2.05.
14260 (_AS_LINENO_PREPARE): Use Sed rather than
14261 Awk. Fix the sed prepass to work even if there are multiple
14262 instances of $LINENO on the same line. Do not substitute for
14263 other variables like $LINENOT. Do not check file dates; such a
14264 check is unreliable on sufficiently fast machines, and removing
14265 the check makes the code simpler and more reliable. Check for
14266 output and chmod failures.
14268 * doc/autoconf.texi (Special Shell Variables): Document
14271 2001-10-31 Akim Demaille <akim@epita.fr>
14273 * tests/Makefile.am (atconfig): Remove this target, Automake
14276 2001-10-31 Akim Demaille <akim@epita.fr>
14278 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14279 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14280 provided, while it is optional.
14281 * configure.ac: Adjust.
14283 2001-10-26 Paul Eggert <eggert@twinsun.com>
14285 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14286 lib/Autom4te/Struct.pm:
14287 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14290 * doc/autoconf.texi (Special Shell Variables): Document some
14291 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14293 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14294 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14295 eval $LINENO is not portable in practice.
14297 2001-10-24 Akim Demaille <akim@epita.fr>
14299 * lib/Autom4te/General.pm (backname): New.
14301 2001-10-24 Akim Demaille <akim@epita.fr>
14303 * m4/: Remove, merged into...
14306 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14308 * doc/autoconf.texi (Shellology): Mention the problems with bash
14309 2.05's use of ANSI quoting in its `set' builtin.
14311 2001-10-22 Paul Eggert <eggert@twinsun.com>
14313 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14314 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14315 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14316 POSIX decided to standardize on the int flavor of strerror_r.
14317 Always do char* test, as there's no reason not to.
14318 Assign to a char* var, to catch strerror_r that returns int*.
14320 * doc/autoconf.texi (Particular Functions):
14321 Document the above changes. Also, document the fact that
14322 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14324 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14326 2001-10-20 Akim Demaille <akim@epita.fr>
14328 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14329 the executable was missing from the log.
14331 2001-10-20 Akim Demaille <akim@epita.fr>
14333 * lib/Autom4te/General.pm (&update_file): If destination is
14334 unchanged, remove the source.
14335 (&up_to_date_p): Don't be verbose, be debug.
14336 * bin/autoreconf.in: No longer support --m4dir.
14337 (&autoreconf): Display the full path of the configure.ac we are
14339 Trace it only once.
14340 Be sure to honor --force with gettextize.
14341 Always run aclocal.
14342 * doc/autoconf.texi: Adjust.
14344 2001-10-20 Akim Demaille <akim@epita.fr>
14346 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14348 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14349 `intl' is already present, as it refuses unless --force.
14350 (&parse_args): Use -I, --include instead of the old Autoconf
14352 ($localdir, $autoconf_dir): Remove.
14354 (&maybe_autoreconf): New, to preserve $_ for File::Find.

14821 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14822 arguments. Fixed a typo.
14824 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14826 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14827 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14829 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14831 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14833 * bin/autoheader.in: Reworded a few comments.
14834 * bin/autoconf.in: Reworded help text for a few options.

14838 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14840 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14841 already have $file). Set output files to binary mode (helps avoid
14842 CR issues on DOSish systems).
14844 2001-09-19 Akim Demaille <akim@epita.fr>
14846 * lib/autotest/general.m4: Englishoes.
14847 From Tim Van Holder and Alexey Mahotkin.
14849 2001-09-18 Paul Eggert <eggert@twinsun.com>
14851 * doc/autoconf.texi (Common Shell Constructs): New node,
14852 documenting AS_DIRNAME.
14853 (Limitations of Usual Tools): Refer to it when discussing dirname.
14854 Also, update discussion of POSIX standard to reflect latest draft.
14856 * lib/autoconf/c.m4:
14857 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14859 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14860 Do not pass a first argument with leading '-'
14861 to expr, by parenthesizing initial integers that might be negative.
14863 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14864 now merely checks whether it is an error to pass an argument
14867 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14868 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14869 whether it is a (compile-time) error to pass an argument to
14870 getpgrp. This simpler test supports the revised documentation,
14871 and is all that AC_FUNC_GETPGRP's users really need.
14873 2001-09-18 Akim Demaille <akim@epita.fr>
14875 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14885 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14887 Add test for AS_BASENAME.
14888 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14889 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14890 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14891 * tests/base.at: Fixed the expected responses. The old ones were
14893 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14894 the documentation claims it should (and how it behaved in 2.13).
14896 2001-09-18 Akim Demaille <akim@epita.fr>
14898 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14899 the AC_CONFIG_COMMANDS invocation.
14900 This also solves the name clash problems.
14901 Don't set the package's ID.
14902 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14903 No longer to be shipped.
14904 (version.in): Remove.

14907 Use `m4_PACKAGE_STRING'.
14908 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14909 the only optional argument is the name of the test suite.
14910 Expect `package.m4' to define the package signature.
14911 * lib/autom4te.in (Autotest): Add `package.m4?'.
14912 * tests/Makefile.am (package.m4): New.
14913 * tests/suite.at: ifnames is a victim.

14917 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14918 AC_LIBSOURCE, AC_CONFIG_FILES.
14919 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14920 program version string doesn't match the package's.
14921 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14924 2001-09-17 Paul Eggert <eggert@twinsun.com>
14926 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14927 Allow expression to return any value that can fit into unsigned long
14928 (not int, as before). Check for output errors.
14930 2001-09-17 Bruno Haible <haible@ilog.fr>
14932 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14933 Always include <stdio.h> and <stdlib.h>. Evaluate
14934 the expression in an extra function before these includes. Call
14935 fprintf "%d" only after ensuring the argument is of type 'int'.
14936 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14938 2001-09-17 Paul Eggert <eggert@twinsun.com>
14940 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14941 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14942 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14943 when they don't exist.
14945 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14946 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14949 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14950 version with the version used by fileutils 4.1, except use
14951 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14954 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14956 2001-09-13 Akim Demaille <akim@epita.fr>

14996 * lib/autotest/general.m4 (AT_INIT): Create and remove
14997 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14998 test suites can cohabit.

15002 * tests/mktests.sh: Don't output banners for empty test files.

15111 the maintainer is dumb enough to do that...
15113 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15114 excellence in M4 quotation: consider `__file__' is active.

15290 * lib/Autom4te/General.pm (&find_peer): Remove.
15291 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

15294 find the executables for it.

15298 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15299 indeed related to running the test suite, while passing

15301 Autoconf executables. So don't do that, leave it to...
15302 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15303 * tests/autoscan: New.
15304 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

15790 autom4te.cache (it's a directory, not a file.
15791 * Makefile.am: Ditto (but maintainer-clean-local).
15793 2001-08-15 Akim Demaille <akim@epita.fr>
15795 * bin/autom4te.in (@m4_warning): New.
15796 (&handle_m4): Use it.
15797 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

15800 is in the src tree.
15802 2001-08-15 Akim Demaille <akim@epita.fr>

15870 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15871 * doc/autoconf.texi (C Compiler Characteristics): Update

15876 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15877 magic values from an object file when cross-compiling.
15878 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15880 2001-08-10 Akim Demaille <akim@epita.fr>
15882 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15884 Suggested by Russ Allbery.
15886 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15888 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15889 current $prefix to the sub-configures.
15891 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15893 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15894 extension (needed on BeOS). Reported by Guido van Rossum.
15896 2001-08-09 Akim Demaille <akim@epita.fr>
15898 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15900 2001-08-07 Akim Demaille <akim@epita.fr>
15902 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15904 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15905 No need to remove the files before and after the each test, before
15906 each test and at the end of the suite is enough.
15907 Display only the children `times', not the shell's.
15908 If the test failed or was skipped, at-times is not available.
15910 2001-08-07 Akim Demaille <akim@epita.fr>
15912 Always produce testsuite.log, including when there are no
15913 failures. This helps getting information on skipped tests, and
15914 duration of the tests. Err, implement the latter btw.
15916 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15917 Dump information on the first run of each test.
15918 (AT_CLEANUP): Create `at-times' containing the duration of the
15921 2001-08-07 Akim Demaille <akim@epita.fr>
15923 The use of `dumpstat' revealed that `len' was used although it
15924 should not. m4_text_wrap was using it, but in the Autoconf world
15925 where it is legal. Hence (i) test M4sh in its own world, not
15926 Autoconf's, and (ii), ahem, fix the bug :)
15928 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15929 does not like `' instead of [].
15930 (AT_INIT): Forbid `^_?AT_'.
15931 And don't output such tokens.
15932 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15933 `script.as', and `autom4te.cache'.
15934 Remove `empty' and `macro' which are no longer used.
15935 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15936 * tests/m4sugar.at: Use it.
15937 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15939 2001-08-07 Akim Demaille <akim@epita.fr>
15941 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15943 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15945 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15947 2001-08-04 Akim Demaille <akim@epita.fr>
15949 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15950 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15952 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15953 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15954 (AC_F77_MAIN): Likewise.
15956 2001-08-04 Akim Demaille <akim@epita.fr>
15958 Don't rely on M4sugar outputting the patterns in files, since we
15959 might process the output _without_ running m4, hence without these
15962 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15963 * bin/autom4te.in (@Request::includes): Remove, unused.
15964 (@Request::source): Rename as...
15965 (@Request::input): this.
15966 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15967 (&handle_output): Fetch the patterns from the traces.
15968 `$forbidden' and `$allowed' are constant: use m//o.
15969 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15970 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15972 2001-08-04 Akim Demaille <akim@epita.fr>
15974 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15975 autoconf', i.e., in addition to caching traces, cache the output.
15977 * bin/autom4te.in (Request::cache): Rename as...
15978 (Request::id): this.
15979 ($cache, $icache, $tcache, $ocache): New.
15980 (&handle_m4): Save M4 output in the cache instead of $tmp.
15981 (&handle_output): Adjust.
15982 (&up_to_date_p): Check that the output cache is up to date too.
15983 (top level): Run `&handle_m4' iff force or the cache is invalid.
15984 Run `&handle_output' if the output cache is more recent.
15986 2001-08-04 Akim Demaille <akim@epita.fr>
15988 * bin/autom4te.in ($force): New.
15989 (&parse_args, &print_usage): -f, --force is a new option.
15990 (&handle_output): CPP directives might have spaces after `#'.
15991 (&parse_args): The first file only can be frozen.
15993 2001-08-04 Akim Demaille <akim@epita.fr>
15995 Don't let autom4te compute the `include' traces several times:
15996 first check that the trace cache file is up to date, and then
15997 compare its timestamp with that of the output.
15999 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16000 the preamble. Don't require 5.005 as Autom4te::General does it,
16001 and better yet (use `use', not `require'!).
16002 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16003 Class::Struct as Autom4te::Struct.
16004 * lib/Autom4te/General.pm (File::stat): Use it.
16005 (&mtime): New, export it.
16006 * bin/autom4te.in: Use it.
16007 Declare `$req' is invalid if it is outdated.
16008 Don't declare it valid before saving it if something went wrong.
16010 2001-08-04 Akim Demaille <akim@epita.fr>
16012 Autom4te shall not encode Autoconf data, and preselecting traces
16013 must be proposed to the users.
16015 * bin/autom4te.in (@required_trace): Remove.
16017 (&parse_args, &print_usage): -p, --preselect is a new option.
16018 (&up_to_date_p): Adjust.

16023 * tests/tools.at (autoconf --trace: user macros): Check traces on
16024 macros invoked without arguments, and macros invoked with multiple

16032 2001-08-03 Akim Demaille <akim@epita.fr>
16034 * bin/autoconf.in ($@): Work around the usual sh bug.
16037 2001-08-03 Akim Demaille <akim@epita.fr>
16039 Clean up the handling of the M4 builtins tracing exception.
16041 * bin/autom4te.in (Request::request): Don't complete M4 builtins

16044 (@m4_builtin): this.
16045 (%m4_builtin_alternate_name): New.
16046 (&parse_args): Complete the trace requests with alternate names.

16052 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
16053 m4_if, and m4_wrap.
16055 2001-08-03 Akim Demaille <akim@epita.fr>
16057 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
16058 (m4_divert_pop): Dump the whole diversion stack when a diversion
16060 * bin/autom4te.in (&handle_output): Remember of the first
16061 occurrence of a possibly undefined macro, not the last.
16062 Complain about the possibly undefined macros in the same order as
16063 the appear in the output.
16064 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16065 * tests/tools.at (autoconf: forbidden tokens, basic)
16066 (autoconf: forbidden tokens, exceptions): No longer sort
16067 autoconf's stderr, as it is now deterministic.
16068 Check that `dnl' is caught.
16070 2001-08-01 Akim Demaille <akim@epita.fr>
16072 * configure.ac: Bump to 2.52c.
16074 2001-08-01 Akim Demaille <akim@epita.fr>

16089 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
16090 `END', as `Autom4te::General::END' will be triggered.
16091 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
16092 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
16093 system to run `mv', `rm', and `cmp'.

16097 * lib/Autom4te/General.pm (&unique): New.
