1727 Cover more potentially problemtic file names. Use the new
1730 Properly handle funny file names for headers in config.status.
1731 The test suite did not cover this bug because the code was not
1732 quoting properly the arguments of `rm -f' (which "fails" silently)
1733 as well as the arguments of `diff' (whose output was redirected to
1734 /dev/null so we couldn't see its error message).

1852 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1854 <DEFAULTS>: Delay computation of variables based on $at_dir...
1855 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1856 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1857 <PARSE_ARGS>: Parse new option.
1858 <HELP_TUNING>: Document it.

1874 * doc/autoconf.texi (Particular Programs): Do not mention the
1875 Autoconf version in which the AC_PROG_INSTALL change was done.
1876 Suggested by Paul Eggert.

1880 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1881 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1882 mode, we change to the source directory, also set $ac_pwd so we
1883 do not go back to the build tree for the next config subdir.
1884 * tests/torture.at (Deep Package): Extend test to contain two
1885 config subdirs on the top level.
1887 Fix parallel `maintainer-check'.
1888 * Makefile.am (maintainer-check-tests): Depend on `all'.
1889 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

1916 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1918 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1919 check_SCRIPTS. Building the wrappers for `all' allows help2man

1939 (m4_require): Use m4_do, not m4_join.
1941 Fix some whitespace tests on cygwin.

1946 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1948 Optimize AC_REQUIRE.

1951 (m4_require): Avoid extra macro calls.

1955 * tests/torture.at (srcdir): Fix quoting.

1958 * tests/autotest.at (srcdir propagation): Copy install-sh to

1961 * tests/base.at (Input/Output): Likewise.
1962 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1963 config.guess, and config.sub to test source tree.
1964 Drop AC_CONFIG_AUX_DIR setting.
1965 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1966 * tests/torture.at (Substitute a 2000-byte string): Drop
1967 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1968 (Substitute a newline, datarootdir workaround): Likewise.
1969 (Define a newline): Adjust for linenumber changes in configure.ac.
1970 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1977 * tests/tools.at (Syntax of the shell scripts): Likewise.
1979 * tests/m4sh.at (LINENO): Quote $0.
1981 Fix testsuite program wrapper for whitespace in `pwd`.
1982 The problem here is that the usual mantra is that command
1983 variables can contain arguments, thus we cannot just escape
1984 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1985 $top_builddir/tests directory early in $PATH, so that the
1986 wrappers are found by their plain name.
1987 * tests/wrapper.as: Put $testdir early in $PATH.

2000 <at_func_create_debugging_script, Driver Loop>:
2001 Quote $at_group_dir.
2002 * tests/autotest.at (whitespace in absolute testdir): New test.
2004 * lib/autom4te.in: Quote @datadir@.
2006 Proper file name escaping in Autoconf programs and Perl modules.
2007 This includes escaping of characters special to the shell
2008 as well as special to Perl, e.g., leading `<' or `>'.
2009 For example, when $file starts with `>', `open ">$file"'
2010 wrongly tries to append to a different file.
2011 * bin/autoconf.as: Fix quoting for autom4te options.
2012 * lib/Autom4te/General.pm (shell_quote): New function, taken
2013 from coreutils, written by Jim Meyering.
2015 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
2017 * bin/autoreconf.in (parse_args): Likewise.
2018 * bin/autoscan.in (main): Likewise.
2019 * bin/autoupdate.in (main): Likewise.
2020 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
2021 * bin/ifnames.in: Likewise, XFile usage fixes.
2022 * tests/tools.at (autom4te and whitespace in file names): Extend
2023 test. Test twice, with special characters allowed on w32, and the
2024 rest. Test leading and trailing whitespace, for `open_quote'.
2025 (autotools and whitespace in file names): New, analogous test.
2026 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
2027 by Russ Allbery and Eric Blake.
2030 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
2031 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.

2057 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2058 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2059 #undef as this runs afoul of our new way of creating config.h.
2060 Problem reported by Jim Meyering in
2061 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

2065 Fix autom4te for unusual characters in input file names.
2066 * bin/autom4te.in (files_to_options): Quote active characters
2068 * tests/tools.at (autom4te and white space in file names):
2071 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2072 Document that Tru64 awk always splits $0.
2074 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2076 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2077 `#AT_STOP_...' line at the end of each test.
2079 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2081 * lib/autotest/general.m4 (AT_INIT): For awk line number
2082 extraction script, ensure `$at_group' has a defined value
2083 even for the empty set, and properly quote its usage inside
2086 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2088 * doc/autoconf.texi (Shell Functions): New chapter. Document
2089 IRIX sh $0 issue in functions, move content from ...
2090 (Portable Shell): ... here.
2091 (Shell Script Compiler): Note that shell functions are not
2092 totally unportable any more.
2094 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2095 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2097 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2098 extracting the line numbers of the last needed test.
2100 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2102 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2105 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2107 Fix IRIX testsuite debugging failures: $0 in functions.
2108 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2109 Do not use $0 inside a function, as IRIX sh will set that to the
2110 function name rather than the script invocation name.
2112 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2113 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2115 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2116 to extract test scripts.
2117 (AT_INIT): Extract and cache test script line numbers.
2119 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2121 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2122 subsequent fixups; the awk -> here-document conversion trashes
2123 performance too much with AIX sh.
2125 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2127 * tests/local.at: Do not test m4, perl with AT_TESTED.
2129 Diagnose and guard against write errors dealing with config.status.
2130 The general idea is this: all write failures from `configure'
2131 writing `config.status' are indicated by $ac_write_error, which
2132 is only checked at the end. This is safe because config.status
2133 code is not executed before the file is complete. Other write
2134 failures, be they inside config.status, or in sub shell/awk
2135 scripts spawned from configure or config.status, typically need
2136 earlier checking, as their results are used right afterwards.
2137 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2138 before writing config.status, check afterwards.
2139 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2140 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2141 Set `ac_write_error' for write failures to config.status. Barf
2142 upon write failures to temporary files.
2143 Adjust note about closing and reopening the here-document.
2144 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2145 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2146 reopening the here-document.
2147 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2148 Ensure `ac_write_error' does not escape into config.status.
2149 Also, add a couple of code paths not yet exercised in the test
2150 suite: a config file with input from stdin, and a config header
2152 Suggestion for catching write errors by Bruno Haible.
2154 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2156 Avoid error with Tru64 awk and testsuite lines with many words.
2157 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2158 reads the testsuite, set the field separator to an unusual value,
2159 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2160 even splits the input if $i, i>0, was never accessed in the script.
2162 Revert 2007-10-17 change.
2163 * TODO: Multiline args in config files and headers mean something
2164 different and are not fixed, see
2165 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2166 Report by Stepan Kasal.
2168 * doc/autoconf.texi (Generic Programs): Fix typo.
2170 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2172 AC_*_TOOL does not canonicalize the prefix
2173 * doc/autoconf.texi (Generic Programs): Do not say that
2174 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2176 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2178 Diagnose write errors in config.status instantiations.
2179 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2180 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2182 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2183 Extend test to also check for some write error failures, using...
2184 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2185 Report by Bruno Haible.
2188 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2190 (_AT_CHECK): Use less indentation, to save space.
2192 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2194 Add witness macro for @top_build_prefix@ substitution.
2195 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2196 (_AC_OUTPUT_FILE): Mention it here.
2198 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2199 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2201 * lib/autotest/general.m4 (at_func_test): Remove.
2202 (AT_INIT): Pre-extract test groups into separate files.
2203 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2204 Remove at-test-source files together with the $at_group_dir.
2205 * tests/autotest.at (Long test source lines): New test.
2207 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2209 Shell functions and variables may share a namespace.
2210 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2213 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2215 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2218 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2220 * lib/autoconf/status.m4: Fix a couple of comment typos.
2222 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2224 2007-11-13 Jim Meyering <meyering@redhat.com>
2226 Clean up the rule to create "expr".
2227 * tests/Makefile.am (expr): Don't redirect directly to target.
2228 Redirect just once, not for each echo statement.
2229 Use $@, not literal "expr".
2231 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2233 Don't worry about preprocessor when testing long long.
2234 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2235 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2236 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2237 These no longer check for preprocessor flaws.
2238 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2239 Do not check for preprocessor flaws.
2241 2007-11-13 Jim Meyering <meyering@redhat.com>
2243 Adapt dependencies, now that a version change doesn't modify configure.ac
2244 * GNUmakefile: Remove "make clean" kludge.
2245 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2247 Don't redirect directly to target.
2248 Use $@, not literal "version.m4".
2250 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2252 * doc/autoconf.texi (Making testsuite Scripts): Document
2253 ":;{" shorthand as in previous patch.
2255 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2257 * doc/autoconf.texi (Limitations of Builtins): Document problem
2258 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2260 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2261 Use ":;{" shorthand.
2262 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2264 2007-11-12 Jim Meyering <meyering@redhat.com>
2266 Add more non-srcdir build support.
2267 * GNUmakefile (dummy): Split a long line.
2268 Add -v option to autoreconf invocation.
2270 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2271 * GNUmakefile (dummy): Remove INSTALL.
2273 Remove racy commands to build scripts in bin/ and tests/.
2274 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2275 are guaranteed to be built, remove the rules that tried to build
2276 them. Before, with a parallel build, these rules could lead to
2277 two processes writing tests/wrapper.in concurrently.
2279 Build in man/ only *after* building in bin/ and tests/.
2280 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2281 in both bin/ and tests/.
2283 Accommodate non-srcdir build-from-checkout.
2284 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2285 Use git's --git-dir=$srcdir/.git option.
2286 Add quotes, in case tarball_version_file contains shell meta-characters.
2287 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2288 * configure.ac: Pass "." to git-version-gen.
2290 Avoid spurious test failures due to version skew.
2291 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2293 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2295 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2296 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2297 Remove conftest.dSYM directory.
2298 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2299 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2300 Remove `conftest.*' recursively.
2301 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2302 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2304 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2306 Report and analysis by Jeff Squyres and Peter O'Gorman.
2308 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2310 Fix typos in variable names.
2311 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2313 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2315 Document that $((expression)) is not portable.
2316 * doc/autoconf.texi (Shell Substitutions): Here.
2318 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2320 Ignore configure --help* errors due to LINENO-impaired shells.
2321 * tests/torture.at (Configuring subdirectories, Deep Package):
2322 In the --help* tests in read-only trees, make `.' temporarily
2323 writable again for the `stderr' file, and ignore errors due to
2324 the attempt to write configure.lineno.
2325 Report by Patrick Welche.
2327 2007-11-10 Jim Meyering <meyering@redhat.com>
2329 Generate package.m4 in build-dir, not srcdir.
2330 * tests/Makefile.am (package.m4): Adjust target.
2331 Don't redirect directly to $@.
2332 (CLEANFILES): Add package.m4.
2333 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2335 When running $(AUTOTEST), search "." before searching $(srcdir).
2337 Avoid a race condition that would make parallel "distclean" fail.
2338 * tests/Makefile.am (distclean-generic): Replace the default,
2339 automake-provided rule with an identical one, but with an additional
2340 dependency on distclean-local. Simply adding the dependency would
2341 cause automake not to emit the rule at all.
2342 * BUGS: Building with -jN works, now.
2344 Distribute git-version-gen.
2345 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2346 since GNUmakefile is distributed, and requires it for dist* rules.
2348 Remove two more generated files from version control.
2349 * INSTALL: Remove generated file.
2350 * lib/autoscan/autoscan.list: Remove generated file.
2352 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2354 * GNUmakefile (PATH): Remove stray apostrophes; they become
2355 part of PATH, which isn't wanted here.
2357 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2359 New config files output variable `top_build_prefix'.
2360 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2362 * doc/autoconf.texi (Preset Output Variables): Document it.
2364 Report by Bob Friesenhahn.
2366 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2367 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2368 function, to parametrize arithmetic with expr vs. the shell.
2369 Use it where possible.
2370 Suggestion by Benoit Sigoure.
2372 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2374 Adjust the documentation of autotest WRT atlocal.
2375 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2376 when using Automake, to write a rule to produce atlocal, since it's
2377 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2378 distributed, not atconfig.in.
2380 2007-11-04 Eric Blake <ebb9@byu.net>
2382 Update list information.
2383 * README: Mention new autoconf-commit list.
2384 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2386 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2388 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2390 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2392 * build-aux/.gitignore: Ignore mkinstalldirs.
2394 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2396 2007-11-03 Jim Meyering <meyering@redhat.com>
2398 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2399 * build-aux/git-version-gen: This syncs from coreutils.
2401 Adjust the build procedure so "make check" works reliably.
2402 * README-hacking: Include an extra step between "make" and
2403 "make check" to ensure that the latter passes.
2405 Use just-built tools, when possible.
2406 * GNUmakefile (PATH): Set and export here, ...
2407 (dummy): ... rather than here.
2409 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2410 and Andreas Schwab <schwab@suse.de>

2415 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2417 * configure.ac (AC_PREREQ): Require version 2.60, for
2418 AC_PROG_SED, AC_PROG_GREP.
2420 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2421 and Jim Meyering <meyering@redhat.com>

2430 2007-11-03 Eric Blake <ebb9@byu.net>
2432 Support m4 1.4.5 in testsuite.
2433 * tests/torture.at (Define a newline): Exclude line numbers in
2435 Reported by Ralf Wildenhues.
2437 2007-11-03 Jim Meyering <meyering@redhat.com>
2439 Remove automake-provided files from version control.
2440 * build-aux/elisp-comp: Remove file.
2441 * build-aux/install-sh: Remove file.
2442 * build-aux/missing: Remove file.
2443 * build-aux/mdate-sh: Remove file.
2444 * build-aux/.gitignore: New file.
2445 Suggestion from Ralf Wildenhues.
2447 2007-11-03 Eric Blake <ebb9@byu.net>
2449 Adjust version comparison to account for git snapshot numbers.

2453 <m4_version_compare>: Document this change.
2454 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2456 2007-10-30 Bruno Haible <bruno@clisp.org>
2458 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2459 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2460 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2461 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2462 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2463 Suggested by Paul Eggert.
2465 2007-10-28 Jim Meyering <meyering@redhat.com>
2467 * README-hacking: Autoconf, Automake, and Perl are required to build.
2468 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2470 2007-10-28 Jim Meyering <meyering@redhat.com>
2472 README-hacking: Recommend running autoreconf -vi.
2473 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2474 so that we use just-built tools when they're available.
2475 Suggestions from Ralf Wildenhues.
2477 2007-10-28 Jim Meyering <meyering@redhat.com>
2479 Make inter-release --version output more useful.
2481 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2482 which indicates that it is built using the 19th change set
2483 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2484 is a prefix of the commit SHA1.
2485 * build-aux/git-version-gen: New file.
2486 * configure.ac: Run it to set the version.
2487 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2488 * Makefile.am (dist-hook): Arrange so that .version appears only
2489 in distribution tarballs, never in a checked-out repository.
2490 * .gitignore: Add .version here, too. Just in case.
2491 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2492 not configure.ac, now that the version number changes automatically.
2494 Ensure that $(VERSION) is up to date for dist-related targets.
2495 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2496 git-version-gen doesn't match $(VERSION), but only for dist targets.
2498 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2507 * aclocal.m4: Remove.
2508 * configure: Remove.
2509 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
2510 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
2511 * README-hacking: New file: how to build from just-checked-out sources.
2513 2007-10-23 Eric Blake <ebb9@byu.net>
2515 Improve corner case of m4_expand.
2516 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

3772 for C++; this drops support for anonymous struct and union types,
3773 which were problematic anyway.

3793 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3794 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3795 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3796 works but the latter doesn't, then it's a valid type.
3797 This lets people use function types and so forth.
3798 For C++ there doesn't seem to be a simple solution, so leave it alone.
3799 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3800 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3801 AC_CHECK_TYPE; that wasn't documented or necessary.

3856 2007-03-17 Jim Meyering <jim@meyering.net>
3858 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3859 (Limitations of Usual Tools): Also list \< and \>, and mention that

3862 2007-03-09 Stepan Kasal <kasal@ucw.cz>

3865 change the build type.

4001 builtin `echo' of some bash versions. Reports by Ian Macdonald
4002 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
4004 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4006 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
4007 separate items of `ac_user_opts', to avoid long lines.
4008 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
4010 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4012 * doc/autoconf.texi: Fix some typos.
4014 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
4016 Fix some wording problems noted by Paolo Bonzini in:
4017 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
4018 * doc/autoconf.texi (Signed Overflow Examples): Give more
4019 discussion about the allow_superuser_privileges example,
4020 and change it a bit to make things clearer.
4021 (Optimization and Wraparound): Clarify whether the compiler
4022 will generate an infinite loop for the example derived from
4023 Autoconf's mktime test.
4024 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
4025 Also, clarify unsigned multiplication overflow.
4027 2007-01-04 Eric Blake <ebb9@byu.net>
4029 * bin/Makefile.am (RELEASE_YEAR): New macro.
4030 (edit): Use it to supply correct copyright year to scripts.
4031 * bin/autoconf.as (version): Use it.
4032 * bin/autoheader.in ($version): Likewise.
4033 * bin/autom4te.in ($version): Likewise.
4034 * bin/autoreconf.in ($version): Likewise.
4035 * bin/autoscan.in ($version): Likewise.
4036 * bin/autoupdate.in ($version): Likewise.
4037 * bin/ifnames.in ($version): Likewise.
4039 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4041 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4042 feedback. The most important changes document what happens when
4043 you convert an out-of-range value to a signed integer type, and
4044 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4047 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4048 rewrite, taking notions from the recent discussion on the gcc and
4049 autoconf mailing lists; please see
4050 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4051 and follow the many links.
4052 (Integer Overflow Basics, Signed Overflow Examples):
4053 (Optimization and Wraparound, Signed Overflow Advice):
4054 (Signed Integer Division): New sections.
4056 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4058 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4059 preprocessor macro arguments in traced name.
4060 * doc/autoconf.texi (Defining symbols): Document longstanding
4061 support for AC_DEFINE-ing macros with arguments, and document
4062 behavior when the same variable has multiple AC_DEFINEs.
4063 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4064 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4065 macros directly, giving much shorter and simpler code.
4067 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4069 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4070 space before "$ac_configure_args" to prevent a 'config.status
4071 --recheck' failure if ac_configure_args doesn't contain a leading
4072 space. This works around a problem with the XEmacs configure.ac,
4073 which uses the (undocumented) ac_configure_args variable
4074 inconsistently with Autoconf.
4076 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4078 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4079 Include <limits.h>, and use its INT_MAX to rewrite the
4080 j loop so that it does not overflow 'int'. Problem reported by
4082 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4083 Play it safe by shifting left by 1 rather than multiplying by 2,
4084 as GCC is less likely to optimize this away when the value
4085 is signed (when it assumes overflow leads to undefined behavior).
4086 Also, don't assume time_t uses two's complement.
4088 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4090 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4091 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4092 dumps core on it. Report by Tim Rice.
4094 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4096 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4097 --disable-option-checking to --help output even when
4098 AC_PRESERVE_HELP_ORDER is not used.
4099 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4100 --with argument, rather than argument with [-.] replaced by
4102 * NEWS: Fix typo in previous change; the news was in the
4105 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4107 * NEWS: Warnings are now generated by default for unknown
4108 --enable-* and --with-* options.
4109 * doc/autoconf.texi (Option Checking): Renamed from
4110 (Configure Option Checking). Tighten up the wording a bit.
4111 (External Software, Package Options): Cross-reference to Option
4112 Checking, and use this to shorten our section.
4113 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4114 "$x" to test "x$foo" != x.
4115 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4116 Don't warn if $enable_option_checking is "no".
4117 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4118 ac_unrecognized_opts to the empty string.
4119 Don't echo the unrecognized opts, as this might mishandle
4120 backslashes or leading -.
4121 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4122 usage next to the other --disable-FEATURE options in the
4125 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4127 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4128 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4129 Print warning for unrecognized --with and --enable options
4130 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4131 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4132 Disable option checking when subdirs are configured.
4133 (AC_OUTPUT): If warnings are enabled, print warning about
4134 unrecognized --with and --enable options at the end of
4135 the configure output (as well as at the beginning).
4136 * doc/autoconf.texi (Option Checking): New node.
4137 Document new option warning functionality.
4139 2006-12-16 Eric Blake <ebb9@byu.net>
4141 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4142 * NEWS: Start news for current version.
4144 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4146 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4147 Define HAVE_GETMNTENT to 1, not to the empty string.
4148 Problem originally reported by Jochen Friedrich in
4149 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4151 This change prompted by a problem report by Andrey Simonenko in
4152 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4153 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4154 object-like macros only, in the traditional portable character
4156 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4157 Warn about attempts to define things that are not identifiers.
4158 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4159 awful hack that AC_DEFINEd macro names containing parentheses.
4161 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4163 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4164 too drastic, even if Texinfo in theory requires it for info mode.
4166 (config.status Invocation): Renamed back from Recreating a
4168 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4169 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4171 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4173 * NEWS: Version 2.61a.
4175 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4176 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4178 * NEWS: Document changes with echo and printf, and the lack
4179 of limits on the total size of multi-line values of substituted
4180 variables, and the AC_FUNC_FSEEKO fix.
4182 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4184 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4185 Writing configure.ac.
4186 (Autoconf Input Layout): Renamed from configure.ac Layout.
4187 (Recreating a Configuration): Renamed from config.status Invocation.
4188 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4189 (acconfig Header): Renamed from acconfig.h.
4190 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4191 (Writing Testsuites): Renamed from Writing testsuite.at.
4192 (Autom4te Cache): Renamed from autom4te.cache.
4194 * BUGS: Remove mention of VPATH problem, since it's now documented
4195 not to be a bug in the Autoconf build procedure itself, but rather
4196 a problem with the proprietary `make' programs.
4198 * doc/autoconf.texi (Build Directories): Add a cross reference
4201 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4202 * doc/standards.texi: Sync from gnulib.
4204 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4205 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4206 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4207 generated automatically.
4209 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4211 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4212 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4213 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4215 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4217 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4218 `CEOF$ac_eof' special marker, the awk script cannot contain a
4219 line matching `^CEOF', so this is not needed any more.
4220 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4221 special marker in the test.
4223 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4225 * tests/tools.at (autom4te preselections): Use `find -newer';
4226 remove one of the sleeps.
4228 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4229 more readable, using ...
4230 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4232 * doc/autoconf.texi (autoheader Invocation): Do not double-
4233 quote the parameter of `AH_BOTTOM' in the example.
4235 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4237 * doc/autoconf.texi (Configuration Headers): Remove the
4238 example with multiple input files.
4239 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4240 multiple input files.
4242 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4244 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4245 creating the awk substitution script, handle one input line at a
4246 time, so that the maximum length of a substituted (multi-line)
4247 value is not limited by the size of the sed pattern space.
4248 The trade-off is a slightly repetitive sed script.
4249 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4250 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4251 * tests/torture.at (Substitute a 2000-byte string): Increase the
4252 test with several long lines, they should not be caught by sed
4255 * tests/tools.at (autom4te preselections): New test, to flag
4256 entries missing from autom4te.cfg.
4257 Report by David Byron <dbyron@hheld.com>.
4259 * tests/torture.at (Substitute a 2000-byte string): Actually use
4260 AC_PROG_AWK, so the last change works as intended.
4261 (Substitute and define special characters): Likewise.
4262 (Substitute a newline): Likewise.
4264 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4265 instead of `awk' consistently.
4266 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4267 * tests/torture.at (Torturing config.status): Test both the
4268 result of AC_PROG_AWK and plain awk.
4269 (Substitute a 2000-byte string): Likewise.
4270 (Substitute and define special characters): Likewise.
4271 (Substitute a newline): Likewise.
4273 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4275 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4276 can be assigned to a function pointer. Problem reported by
4277 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4278 part of a patch by Ralf Wildenhues in that same bug report.
4280 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4282 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4283 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4285 2006-12-01 Eric Blake <ebb9@byu.net>
4287 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4288 cross-compiling from cygwin to mingw.
4289 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4290 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4291 to lib/autoconf/c.m4.
4293 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4295 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4296 string for more reliable failure. Wrap the entire test that
4297 causes the broken Solaris printf to dump core, in a subshell,
4298 so the segmentation fault message is reliably suppressed.
4299 Fix shell expansion errors by using /usr/ucb/echo always;
4300 avoid an error on systems without it by another subshell.
4301 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4302 subshell-$as_echo to `as_echo', for better error message.
4304 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4306 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4307 `BASH_SOURCE' contain a newline, set them to empty, as they may
4310 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4312 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4313 years and is too hard to maintain now. The last straw was
4314 reported by Jerker Baeck in
4315 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4316 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4317 * doc/autoconf.texi (Particular Functions): Move
4318 AC_FUNC_SETVBUF_REVERSED from here...
4319 (Obsolete Macros): ... to here. Say that it does nothing now.
4320 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4321 Turn into (almost) a no-op.
4323 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4325 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4326 These macros are obsolescent and new applications shouldn't need them.
4327 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4328 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

4332 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4333 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4334 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4336 * doc/autoconf.texi (Setting Output Variables): Mention that
4337 @VAR1@VAR2 has unspecified behavior. Problem reported by
4339 * NEWS: Mention this.
4341 * Makefile.am: Put only a single '#' into the copyright notice,
4342 so that it's also present in the output file. Standardize wording
4343 in makefile copyright notices to match GNU coding standards.
4344 * bin/Makefile.am: Likewise.

4357 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4359 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4360 in the sed script that mangles the awk script: delete up to the
4361 first exclamation mark only.
4362 * tests/torture.at (Substitute and define special characters):
4365 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4367 Rewrite config files generation: avoid quadratic growth in
4368 the number of substituted variables by using awk instead of sed
4369 for the bulk of the substitutions.
4370 * NEWS: Mention this.
4371 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4372 forbidden in the output (and thus input) file.
4373 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4374 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4375 generate just one large awk script for substitutions,
4376 eliminating much of the earlier complexity, while adding some
4377 new complexity. Only expand the substitution templates at
4378 configure time, for smaller configure script size. If
4379 _AC_SUBST_FILES are used, test 'awk' for working getline support
4380 at config.status time. If absent, interpolate through the
4381 shell. The awk script was written with much help
4382 from Paolo Bonzini and Paul Eggert.
4383 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4384 (_AC_SED_FRAG_NUM): Likewise.
4385 (_AC_SUBST_CMDS): Renamed from...
4386 (_AC_SED_CMDS): ...this.
4387 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4388 * tests/torture.at (Substitute a 2000-byte string): Also
4389 substitute a line with 1000 words, and a variable with several
4391 (Substitute and define special characters): Test awk special
4392 characters, and put substitution input strings `@foo@' in the
4393 output, to test that no recursion happens; test several other
4394 combinations from Paolo Bonzini.
4396 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4398 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4399 that replaced echo with AS_ECHO where this wasn't necessary.
4400 Problem reportd by Ralf Wildenhues.
4401 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4402 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4403 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4405 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4407 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4409 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4411 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4412 that traditional Awk lacks 3-arg "split". It has it.
4413 Mention that FS must be a single character, and a few other
4414 99-byte limits of traditional Awk.
4415 Mention that if (i in a) doesn't work with traditional Awk.
4417 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4419 * tests/autotest.at (BSx641-newline in command):
4420 (BS-BS-newline in command, BSx640-newline in command):
4421 (Newline-CODE-BS-newline in command):
4422 (Single-quote-BS-newline in command):
4423 (Single-quote-newline-BS-newline in command):
4424 Use printf '%s\n' instead of echo, for portability to hosts
4425 where echo interprets backslashes. This will break on hosts
4426 that lack printf, but for now let's assume all such hosts
4427 are dead (if not, we should get reports of test failures).
4429 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4431 'echo' has some portability problems, when given a first argument
4432 with a leading '-', or when given any argument containing '\'.
4433 Avoid using 'echo' in these cases.
4434 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

4436 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4437 * lib/autotest/general.m4 (AT_INIT): Likewise.
4438 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4439 argument might be unportable.

4462 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

4585 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4588 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4590 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4591 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4592 Imported from a similar patch to gnulib by Bruno Haible.

4623 Single-quote in a test title,
4624 Double-quote in a test title): Don't expect failure anymore.
4625 (Backslash in a test title): Put a non-whitespace character after the
4626 backslash so that Bourne shells might actually see it as an escape
4628 (Brackets in a test title,
4629 Pound in a test title,
4630 Comma in a test title,
4631 Quoted Macro in a test title,
4632 Macro in a test title,

4635 Macro with double-quote in a test title,
4636 Macro with backslash in a test title): New tests expected to fail.
4637 * tests/torture.at (#define header templates): M4-quote this title in
4638 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4639 The visible effect was a stray [] in the testsuite output.
4641 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4643 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4644 `trap ... 0' inside a function, for AIX sh.
4646 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4648 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4649 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4650 5363) simply issues a warning when dividing by zero at compile
4651 time. Problem reported by Elias Pipping.
4653 2006-10-26 Eric Blake <ebb9@byu.net>
4656 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4657 show effect on macros that expand with commas.

4682 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4684 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4685 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4686 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4687 reported by Nelson H. F. Beebe for Coreutils 6.4.
4689 * tests/tools.at (autoconf --trace: user macros): Remove test
4690 for tracing multiline macros, since m4 1.4.7a uses a different
4691 way to number lines. Problem reported by Ralf Wildenhues.
4693 2006-10-24 Stepan Kasal <kasal@ucw.cz>

4718 * doc/autoconf.texi (Caching Results): Likewise.
4719 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4720 AC_CACHE_CHECK_INT, since it's no longer public.
4721 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4722 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4750 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4752 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4753 looking for special shell characters.
4754 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4755 macro defined by AS_VAR_PUSHDEF before passing it as a

4767 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4769 (Imported from Automake.)
4770 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4771 which incorrectly sets the mode of an existing destination
4772 directory. In some cases the unpatched install-sh could do the
4773 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4774 system. We hope this is rare in practice, but it's clearly worth
4775 fixing. Problem reported by Alex Unleashed in
4776 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4777 Also, don't bother to check for -m bugs unless we're using -m;
4778 suggested by Stepan Kasal.
4780 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4782 Import this change from Automake:
4784 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4785 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4786 is enabled by default with gnu and gnits strictness.
4787 Report from Bruno Haible.
4789 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4791 gnu and gnits modes.
4793 Import this change from Config:

4798 Import this change from Gnulib:
4800 2006-09-16 Karl Berry <karl@gnu.org>
4801 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4802 to avoid sectioning errors.
4804 Import these changes from Texinfo:

4807 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

4811 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4812 (\code): must use new \...Char values, since now ` is active.
4814 2006-08-26 Karl Berry <karl@gnu.org>
4815 * build-aux/texinfo.tex (\textdegree): New command.
4817 2006-08-12 Karl Berry <karl@gnu.org>

4822 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4824 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4826 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4827 added to the template can get mangled.
4829 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4831 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4832 include the default headers, and redefine obstack_chunk_alloc
4833 and obstack_chunk_free. Fixes false failure with glibc.
4835 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4837 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4838 for backward compatibility with Libtool 1.5.22. Problem reported
4841 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4843 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require

4847 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4849 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4850 the NonStop platform.
4851 * doc/autoconf.texi (Posix Variants): Likewise.
4852 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4854 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4855 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4856 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4857 Use a better substitute, by inspecting the output of "ls"
4858 rather than just using ":".
4859 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4860 rather than AS_EXECUTABLE_P, since we needn't worry about
4861 non-regular files here.
4863 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4864 due to configuration hassles with this. See Tonya Underwood's report
4865 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4869 Stepan Kasal <kasal@ucw.cz>
4871 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4872 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4874 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4876 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4877 initialization which is not inherited through the environment
4878 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4879 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4881 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

4884 problems with mkdir -p -m.
4886 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4888 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4889 comment about ac_cpp_err; it was incorrect, and anyway
4890 ac_cpp_err is being removed below.
4891 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4892 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4893 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4895 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4896 with werror_flag and conftest.err and so forth. This is more
4897 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4898 and anyway the user shouldn't normally want to see this gorp logged.
4899 Problem reported by Ralf Wildenhues.
4900 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4901 empty, not 'no', since the rest of the code uses 'test -z'.
4903 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4905 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4906 Use a single call to AC_DO_TOKENS rather than multiple, for
4908 (_AC_LINK_IFELSE): Test that resulting file is executable.
4909 Problem reported by mwoehlke in
4910 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4912 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4913 than creating a file to use with test -x; this is much faster.
4915 2006-10-02 Bruno Haible <bruno@clisp.org>

5369 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5371 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5372 compiler complains about it, even if things works after the
5373 complaint. Problem reported by Peter O'Gorman.
5375 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5376 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5377 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5379 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5381 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5382 after -R regardless of host. Patrick Welche reports that this
5383 fixes things on NetBSD 3.99.
5385 * NEWS: Recommend M4 1.4.5.
5387 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
5388 * tests/tools.at (autom4te cache): Update wording of diagnostic
5391 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5393 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5394 under AC_C_VOLATILE.
5395 (Volatile Objects): Be a little less skeptical about what
5396 "volatile" means. Derived from thoughts by Ben Pfaff in
5397 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5399 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5401 * doc/autoconf.texi: Fix some typos.
5403 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5405 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5406 more globally, since the 2006-06-30 patch didn't suffice. Problem
5407 reported by Keith Marshall. Also, don't bother with builddir2,
5408 since it shouldn't be needed any more.
5410 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5412 * doc/autoconf.texi (Generic compiler characteristics):
5413 Document AC_COMPUTE_INT. Fix wrong statements on Default
5414 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5416 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
5417 (_AC_COMPUTE_INT): Add obsoletion warnings.
5418 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
5421 * NEWS: Document change.
5423 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5425 * doc/autoconf.texi (Volatile Objects): New section.
5427 * NEWS: Document previous change.
5429 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5431 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5432 Require that long long int be at least 64 bits wide. C99 requires
5433 this and enough programs depend on it so we should check for it.
5434 Bruno Haible reports in
5435 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5436 that long long int is 32 bits wide with some nonstandard compilers.
5437 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5439 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5441 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5442 to a nonexistent file, so that we don't have to worry about
5443 a local site configuration that doesn't use /usr/local.
5444 Problem reported by Keith Marshall in
5445 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5447 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5449 * doc/autoconf.texi: Be more consistent about using @acronym with
5450 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5451 quite right (it talked about "OSF/Tru64", even though the
5452 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5453 and it even mentioned "OSF 4"!) and at this point there's little
5454 reason to talk about OSF any more, since it died in 1994.
5455 (Specific Compiler Characteristics): Simplify example of
5456 negative-size array.
5457 (File Descriptors): Reorder to make the text flow better.
5458 Remove joke about "appreciate the various levels"; I didn't get it.
5459 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5460 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5461 (File Descriptors, Limitations of Usual Tools):
5462 Tone down the advice against renaming or removing open files.
5463 (Limitations of Usual Tools): Add a new section, on 'rm'.
5465 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5467 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5468 -lXt in LIBS, idea from Karsten Hopp; this was due since
5471 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5472 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5473 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5474 (which belong to Xt, not X itself). See Debian bug 327655.
5476 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5478 * configure.ac (AC_INIT): Bump to 2.60a.
5481 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5485 * configure.ac, NEWS: Update.
5487 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5489 * config/texinfo.tex: Sync from upstream.
5491 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5492 quadrigraph correctly in traces.
5494 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5497 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5498 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5500 * doc/autoconf.texi (Changed Directory Variables): New node,
5501 to document the whole `datarootdir' business a bit better.
5503 * tests/torture.at (datarootdir workaround): Extend test.
5504 Prompted by report by Alexandre Julliard.
5506 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5508 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5509 when using default mode of IBM C 6 for AIX. Problem and two-line
5510 fix reported by Larry Jones.
5512 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5514 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5515 about literal '${datarootdir}' if a definition is found in the
5518 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5520 * NEWS: Use "M4" rather than "m4" when appropriate.
5521 Problem reported by Eric Blake.
5522 * doc/autoconf.texi: Likewise.
5523 Use @acronym around BSD, GCC, and GNU when appropriate.
5524 (Why GNU M4): Renamed from "Why GNU m4".
5525 (Redefined M4 Macros): Mention that Posix
5526 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5527 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5530 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5532 * bin/autom4te.in (handle_output): Do not forbid the empty
5534 * tests/tools.at (autoconf: the empty token): New test.
5536 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5538 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5539 calls, so that we do not care whether they are LIFO or FIFO;
5540 in the m4_wrap, do not check which diversion is the topmost
5541 one, just check that the stack is balanced at the end.
5542 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5543 base diversion forever--pop the previous diversion before
5544 opening the new one; consequently, remove the m4_wrap call.
5545 * lib/autotest/general.m4 (AT_INIT): Likewise.
5546 * tests/m4sugar.at: Do not use
5547 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5549 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5550 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5552 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5553 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5554 Rework example of m4wrap token-pasting trouble so that it doesn't
5555 care whether it's LIFO or FIFO.
5556 Fix some "contrary to"s that are awkward in English.
5558 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5560 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5561 to `yes' instead of `int$1_t' if the type is found, for more
5562 consistent configure output (where $1 is the number of bits).
5563 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5564 Suggested by Bruno Haible.
5566 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5567 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5568 with system headers. Report by Bruno Haible.
5570 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5572 * config/config.guess, config/config.sub: Sync from upstream.
5574 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5575 in order to avoid picking up an older installed frozen m4sh.m4f.
5576 Besides an outdated shell startup, this could have been created
5577 by an earlier M4 version with incompatible frozen file format.
5579 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5581 * README: Recommend m4 1.4.4 instead of 1.4.3..
5582 * doc/autoconf.texi: Likewise.
5583 (Special Chars in Names): Say that $(.FOO) is portable, as
5584 suggested by Stepan Kasal.
5585 (Installation Directory Variables, Build Directories):
5586 (Automatic Remaking, Subdirectories, Fortran Compiler):
5587 (Making testsuite Scripts, Defining Directories):
5588 Quote variable usages better.
5589 (Making testsuite Scripts): Add clean-local rule to makefile
5590 snippet, by Eric Blake.
5591 (Installation Directory Variables): Fix table item font.
5592 Reword slightly to clarify. Generalize advice about
5593 not using special characters to include all file-related
5594 vars, not just VPATH.
5595 (Special Chars in Variables): Warn about special characters in
5597 (Assignments): Clarify default-value example as suggested by
5599 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5600 (Special Shell Variables): Note leading ./ or ../, as suggested
5602 (Limitations of Builtins): Under cd, warn about CDPATH.
5603 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5606 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5608 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5609 `@var', for texi2html.
5610 (Systemology): Some more word wrapping, for DVI output.
5611 (autom4te Invocation): The short option for `--melt' is `-M',
5614 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5616 * doc/autoconf.texi: More formatting and English tweaks,
5617 many suggested by Ralf Wildenhues.
5618 Reword to avoid "@code{...}'s" and the like, since it's ugly
5619 with Emacs info mode. discontents -> woes.
5620 Put a few "will"s back. time stamp -> timestamp.
5621 side-effect -> side effect.
5623 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5625 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5626 Warn about $@ not persisting. Problem reported by Julien Danjou in
5627 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5628 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5629 Mention other special chars, too.
5631 2006-06-14 Eric Blake <ebb9@byu.net>
5633 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5635 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5637 * doc/autoconf.texi: Some systematic minor improvements, as
5638 follows. Use "makefile" when talking about makefiles
5639 generally (which might be named "makefile" or "Makefile" or even
5640 "foo.mk"), "Makefile" when talking about a specific makefile
5641 called "Makefile". This unclutters the text from weird quotes
5642 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5643 values" rather than "@var{foo}s" and similar constructs containing
5644 "}s". Use "Make rules" rather than "Makefile rules". Minor
5645 English-language improvements. Change the prefix "sub-" to "sub"
5647 Put blank lines around examples more consistently.
5648 Avoid "rather" and "very" as intensifiers.
5649 Avoid "will" as an auxiliary.
5650 (Limitations of Make): Split this node into....
5651 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5652 (Leading _ in Macro Names, Backslash-Newline-Newline):
5653 (Backslash-Newline Comments, Long Lines in Makefiles):
5654 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5655 (obj/ and Make, make -k Status, VPATH and Make):
5656 (VPATH and Double-colon, $< in Explicit Rules):
5657 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5658 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5659 New nodes, resulting from splitup of Limitations of Make.
5660 All cross-references changed. Raise the top node from
5661 a section to a chapter, and all subnodes accordingly.
5662 Redo the introductory wording to match the new organization.
5663 (Installation Directory Variables): Use an example that is
5664 closer to what Autoconf actually does. Mention that VPATH's
5665 value should not contain metacharacters or white space.
5666 (Fortran Compiler): Fix a VPATH bug in an example.
5667 (Leading _ in Macro Names): Mention that this problem is no longer
5668 of practical concern.
5669 (VPATH and Make): Reword the advice to make it clearer
5670 that Autoconf and Automake support VPATH in non-GNU make, but
5671 many packages have bugs in this area.
5672 ($< in Explicit Rules): Refer to Build Directories rather
5673 than using a (non-VPATH-safe) example.
5674 (Automatic Rule Rewriting): Mention the sort of disaster that
5675 can ensue with Solaris-style rule rewriting with VPATH.
5677 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5679 * doc/install.texi (Compilers and Options): Weaken the
5680 suggestion to use GNU make for VPATH builds.
5682 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5683 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5685 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5686 in regular expression.
5688 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5690 * doc/autoconf.texi (Installation Directory Variables):
5691 Drop extra @samp from `@table @samp' item.
5692 (Limitations of Usual Tools): Comment fix.
5693 Do not nest @samp just to point to other table items.
5694 (Writing testsuite.at) <AT_CHECK>: The second argument to
5695 `@dvar' is already @samp'ed.
5696 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5697 do not use @var in the second argument.
5699 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5701 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5702 $as_shell.exe too. Problem reported by Andreas Buening in
5703 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5705 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5707 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5708 `unused variable' compiler warning, for `-Wall -Werror'.
5709 Reported by Jaap Haitsma in
5710 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5712 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5714 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5715 case the compiler dumps core. Problem reported for
5716 OpenServer 5.0.7 by Tim Rice in
5717 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5718 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5721 2006-06-06 Tim Rice <tim@multitalents.net>.
5723 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5724 "ERROR" only shows up in "make check" output if there is an
5727 2006-06-06 Eric Blake <ebb9@byu.net>
5729 * tests/tools.at (automatically allowed tokens): Fix typo.
5731 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5733 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5735 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5736 typically overflows on x86 CPUs, even though the C standard
5739 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5741 * configure.ac (AC_INIT): Bump to 2.59e.
5744 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5748 * config/texinfo.tex: Sync from upstream.
5750 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5751 seen, invoke libtoolize with `--ltdl' argument.
5752 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5754 Suggested by Eric Blake.
5756 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5758 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5759 reported by Ralf Wildenhues.

5773 message issued by AC_REQUIRE.
5774 * tests/m4sugar.at: Check m4_require's error message.
5775 * tests/base.at: Check AC_REQUIRE's error message.
5776 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5778 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5780 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5781 `expout' as the last parameter.
5782 * tests/tools.at: Adapt to the above change.
5784 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5786 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5787 information about race-free implementations of mkdir.

5796 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5798 * NEWS: GNU make now recommended for VPATH builds.
5799 Mention that some macros are now documented to be obsolescent.
5800 * doc/autoconf.texi:
5801 Prefer "current" to "modern" to describe
5802 currently-used (albeit perhaps old-fashioned) hosts.
5803 Mention which ancient features no longer need to be worried about.
5804 setgid -> set-group-ID
5805 setuid -> set-user-ID (these are the Posix terms)
5806 Fix some misuses of "only".
5807 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5808 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5809 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

5816 Mention that these macros are obsolescent.
5817 (Installation Directory Variables): shall -> should
5818 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5819 Mention that it's now safe to use 3 and 4.
5820 (Limitations of Usual Tools): cp -r is now specified by Posix.
5821 Omit longwinded and obsolescent discussion of cp -f.
5822 Modernize discussion of expr, ls.
5823 (Limitations of Make): Modernize discussion of VPATH builds.
5824 Mention $? as a workaround in some cases.
5825 * doc/install.texi (Basic Installation):
5826 Mention "./configure; make; make install" first. Be more
5827 specific about why this file is generic. Remove unnecessary
5828 parens. Remove misleading "only". Remove obsolete advice
5829 about csh. Don't say "configure" takes awhile; say it
5830 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5831 and CC=c99 rather than CC=c89, as these are blessed by current
5832 Posix. Recommend GNU make if doing a VPATH build.
5834 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5836 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5837 examples involving shell prompts.

5848 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5850 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5852 * doc/autoconf.texi (File System Conventions): Warn about ":"
5853 anywhere in directory names.
5855 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5857 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5858 about quoting the case statement, just in case.
5859 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5860 was fixed in ksh93g; reported by Ralf Wildenhues.
5862 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5864 * doc/autoconf.texi (System Services): Do not document
5865 overriding EXEEXT via ac_cv_exeext=ext.
5866 (Particular Programs) <AC_PROG_MKDIR_P>:
5867 Document that ${MKDIR_P} understands --.
5868 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5871 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5873 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5874 argument with leading hyphen. Problem reported by Paul Eggert.
5876 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5878 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5879 about quoting ac_try: quote all of it, if any of it seems suspicious.
5880 This means we don't have to worry about ${ or sed any more.
5881 Also, double-quote the case statement, to work around misuses via
5882 underquoting as reported by Ralf Wildenhues in
5883 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5884 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5885 undocumented and dangerous macro.
5886 Problem reported by Ralf Wildenhues in
5887 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5889 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5891 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5892 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5893 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5895 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5897 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5898 since evidently some packages rely on the old, broken behavior.
5899 Problem reported by Ralf Wildenhues in
5900 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5901 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5902 pre-2006-05-26 definitions, but leave in the comments that
5903 these macros are dangerous and should not be used.
5904 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5905 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5906 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5907 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5908 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5910 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5912 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5913 the use of 'tr', since this is our only use of 'tr'.
5915 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5916 and Paul Eggert <eggert@cs.ucla.edu>
5918 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5919 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5921 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5923 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5924 the output file in the `${datarootdir}' test.
5926 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5927 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5929 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5930 mention of `datarootdir' in the input file(s), but literal
5931 `${datarootdir}' in the output file, and we haven't warned yet,
5932 then warn as well: the user may have (erroneously) used
5933 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5934 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5935 * tests/torture.at (datarootdir workaround): Extend this test.
5938 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5939 and Paul Eggert <eggert@cs.ucla.edu>
5941 * doc/autoconf.texi (autoheader Invocation): The first argument to
5942 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5943 alternatives and clear up the language a bit.
5945 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5947 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5948 ac_config_guess, ac_config_sub, ac_configure.
5949 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5950 Fix typo that prevented an unnecessary space from being removed.
5951 Problems reported by Ralf Wildenhues in:
5952 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5954 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5956 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5957 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5958 Don't use the term "thread-safe" to talk about mkdir race
5959 conditions, since the problem is more a process than a thread
5960 issue. Problem reported by Stepan Kasal in:
5961 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5962 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5963 the test for 'install' more closely. Look at MKDIR_P first.
5964 Look in the PATH, and at /opt/sfw/bin.
5965 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5966 Don't bother to try mkdir -p, since we already check mkdir --version;
5967 just look at the version number. (There's no easy way to check
5968 for race-free implementations.)
5969 * tests/tools.at (autoconf: subdirectories): Adjust to above
5970 changes, since MKDIR_P now might end in "/mkdir -p".
5972 * doc/autoconf.texi (autoheader Invocation): Mention that the
5973 first arg of AC_DEFINE_UNQUOTED must be a literal.
5974 Problem reported by Ben Pfaff in
5975 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5977 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5978 * doc/autoconf.texi (Special Chars in Variables): New section.
5979 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5980 (Installation Directory Variables): Quote $(datadir) better.
5981 (Limitations of Builtins): Describe some of eval's trickiness.
5983 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5984 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5985 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5986 in front of every arg, not just trailing args. Quote apostrophes.
5987 (_AC_EVAL_ECHO): New macro.
5988 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5989 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5991 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5992 exposed by quoting of eval argument. Put the command on line line
5994 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5995 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5996 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5997 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5998 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5999 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
6000 Use eval more safely.
6001 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
6002 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
6004 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
6005 lines, exposed by quoting of eval argument.
6007 2006-05-26 Stepan Kasal <kasal@ucw.cz>
6008 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6010 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
6011 initialization of `ac_cv_exeext', do not override it if it was
6012 already set, unless it was set to `no', for compatibility with
6013 Autoconf-2.13, and comment this.
6014 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
6015 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
6016 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
6017 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
6018 Document that this test may be overridden by setting
6021 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6023 Revert these two patches:
6025 2006-04-06 Eric Blake <ebb9@byu.net>
6026 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6027 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6030 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6031 Clean up _AC_COMPILER_EXEEXT* macros.
6032 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6033 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6034 ac_file to the name of the default output file and call
6035 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6036 initial `rm' of the candidate files...
6037 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6038 the same list in subsequent `rm' calls, and for the temporary
6039 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6040 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6041 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6042 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6043 no longer needed) by libtool. Make it a cache check.
6044 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6045 copied here by mistake.
6046 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6047 _AC_COMPILER_EXEEXT.
6048 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6049 _AC_COMPILER_OBJEXT directly.
6050 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6052 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6054 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6055 Fix description of how the buggy `sed' works.
6057 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6061 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6062 ENOLCK. Only mention `make -j' when applicable. Only raise
6063 fatal errors when `make -j' is involved. Improve error message.
6065 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6067 * doc/autoconf.texi (Here-Documents): We now know more about
6068 the variable expansion in here documents bug.
6069 Thanks to Tim Rice and Stepan Kasal.
6071 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6072 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6074 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6076 * tests/autotest.at (Multiline command from M4 expansion):
6077 No failure to be expected if the shell quotes newlines in
6078 commands in the `set -x' output. Report by Tim Rice.
6081 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6083 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6084 expansion in the here-documents used by config.status, as that
6085 runs afoul of the Korn shell version M-12/28/93d bug described in
6086 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6087 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6088 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6090 2006-05-23 Jim Meyering <jim@meyering.net>
6092 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6093 Fix typo introduced with 2006-04-02 change. It reversed the sense
6096 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6098 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6099 ac_dB slightly, to save bytes in the script.
6100 Max out at 50 lines, rather than 96; this is more likely
6101 (though not guaranteed) to avoid obscure 'sed' failures.
6103 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6105 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6106 `tr -d -' as bad option argument. Work around this by deleting
6107 an unrelated character.
6108 Report by Tim Rice <tim@multitalents.net>.
6110 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6111 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6112 Stepan Kasal <kasal@ucw.cz>
6114 * doc/autoconf.texi (Particular Programs): Do not promise that
6115 we always prefer the GNU version of the program, and that we
6116 search according to PATH; both rules can have exceptions.
6117 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6118 AC_PROG_SED. Move descriptions of limitations
6119 to the Limitations of Usual Tools section.
6120 (Limitations of Usual Tools) <sed>: Mention script length
6121 limitations with Solaris /usr/ucb/sed.
6122 <grep>: Fix wording for empty alternative. Mention that -c and
6123 -l should not be combined, and that -E and -F should not be
6126 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6127 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6129 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6130 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6132 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6134 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6135 AC_DEFINE is now passed to m4_pattern_allow.
6136 * NEWS: Mention that; likewise for AC_SUBST.
6137 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6138 the parameter to m4_pattern_allow.
6139 * tests/tools.at: Add a check for that.
6141 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6143 * lib/autoconf/status.m4: Fix typos.
6145 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6147 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6148 only the files that this macro generates.
6150 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6152 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6153 the HP-UX sed limitation of 99 commands, labels do not count.
6154 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6156 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6158 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6160 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6161 Import the following fix from coreutils:
6163 2006-01-13 Jim Meyering <jim@meyering.net>
6165 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6166 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6167 not double-quote uses of that variable, to accommodate the rare
6168 case in which getmntent is available in none of the libraries
6169 checked. This happens at least on FreeBSD 5.0.
6171 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6173 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6174 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6175 some other programs unwisely rely on these undocumented vars.
6176 But put in warning comments about them.
6177 Problem reported by Ralf Wildenhues in
6178 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6179 * NEWS: Document that these variables are intended to go away.
6181 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6183 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6184 and set the language to C++ (analogous to the equivalent Fortran
6187 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6188 * doc/autoconf.texi (C++ Compiler): Document it.
6189 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6192 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6194 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6195 that caused config.status to generate 100-command sed scripts; the
6196 portable limit is 99.
6198 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6200 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6201 variable `ac_d' instead of `d' to avoid infringing namespace.
6202 Report by Ralf Menzel.
6204 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6206 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6207 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6208 * tests/tools.at (autoconf: subdirectories): New test, taken from
6209 the corresponding problem report by Ralf Wildenhues in:
6210 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6212 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6213 Quote some uses of shell variables if they might suffer unexpected
6214 globbing. This doesn't fix all instances of quoting problems that
6215 I found, just the easy ones that look safe.
6216 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6217 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6218 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6219 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6220 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6221 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6222 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6224 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6225 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6227 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6229 * bin/autoreconf.in ($help): Reword according to the manual.
6230 Suggested by Olly Betts.
6232 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6233 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6235 * bin/autoreconf.in: Pass the directory argument to
6236 `require_configure_ac'. Fix comment.
6237 * tests/torture.at (Configuring subdirectories): Expose this.
6238 Reported by Olly Betts.
6240 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6242 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6243 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6244 Automake as follows:
6246 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6247 `$configure_in' instead of `configure.in', to preserve
6248 directory component.
6250 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6252 * config/config.guess, config/config.sub, config/texinfo.tex,
6253 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6255 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6257 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6258 test for C99 conformance; (bool) 0.5 is an integer constant
6259 expression, but (bool) -0.5 is not. Problem reported by Fedor
6260 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6262 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6264 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6265 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6266 Warn about obsolete install-sh files. Remove stray sentence
6267 fragment and fix cross reference.
6268 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6269 install -d; this undoes the 2006-05-10 change.
6270 (MKDIR_P): Mark with AN_MAKEVAR.
6271 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6272 that we don't require $INSTALL to be thread-safe. Move comments
6273 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6274 of AC_PROG_INSTALL. Output a message saying that we're checking
6275 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6276 MKDIR_P instead of AC_SUBST.
6277 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6278 Special magic for MKDIR_P, too.
6279 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6281 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6283 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6285 Sync from Automake, as follows:
6287 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6288 * config/install-sh: Initialize IFS, so field splitting isn't
6290 * config/mkinstalldirs: Likewise.
6291 * config/missing: Remove superfluous quotes. Replace all uses of
6292 `[' by `test', for consistency, and for..
6293 * config/missing (sed_minuso, sed_output): New variables.
6294 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6295 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6296 Fixes `missing' to detect `--output' for help2man. Fixes
6297 PR automake/483. Report by Dennis J. Linse.
6298 (autom4te): Document in `missing --help'.
6300 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6302 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6303 * config/install-sh: Don't use 'path' to talk about file names,
6304 as per GNU coding standards. Close a race condition reported by Ralf
6305 Wildenhues and Stepan Kasal. There is still a race condition
6306 on hosts that predate Posix 1003.1-1992, but we can't help this.
6307 Don't mishandle weird characters like space on pre-Posix hosts.
6308 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6309 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6310 AC_PROG_MKDIR_P from AS_MKDIR_P.
6311 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6312 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6313 earlier editions are not (including Automake 1.8.3).
6314 Do not suggest mkinstalldirs for thread-safety.
6315 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6316 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6317 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6318 presence of special characters and race conditions.
6319 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6320 in Autoconf's name space.
6322 2006-05-10 Bruno Haible <bruno@clisp.org>
6323 and Paul Eggert <eggert@cs.ucla.edu>
6325 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6326 from Automake with minor changes.
6327 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6329 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6331 * config/install-sh: Update to Automake CVS version, as follows:
6332 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6333 * lib/install-sh: Simplify the expr implementation of dirname.
6334 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6335 * lib/install-sh: Handle --, and diagnose unknown options.
6337 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6339 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6340 `./autom4te' to create `./testsuite', since the `all' target
6341 will ensure its presence, but `installcheck' should not create
6342 the uninstalled wrappers.
6344 * tests/torture.at (Unusual Automake input files): Skip if we
6345 detect automake < 1.8.
6347 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6349 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6350 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6351 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6354 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6356 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6357 munge (multiple) white space and other oddities.
6358 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6359 single quotes in variable assignment.
6360 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6361 and similar failures by adding multiple spaces, tabs, and other
6363 Report and different test suggested by Francesco Romani
6364 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6366 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6367 single quotes, we only need to search for single quotes; this
6368 both simplifies the search pattern, and makes us less
6369 susceptible to `echo' variations for arguments not containing
6371 (_AC_ARG_VAR_VALIDATE): Likewise.
6373 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6375 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6376 `$*' and IFS concatenation issue with traditional shells and
6377 bash-2.04. Report by Seanster@Seanster.com.
6379 2006-05-03 Bruno Haible <bruno@clisp.org>
6381 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6382 precisely which Mac OS X versions have the od problem.
6384 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6386 * doc/autoconf.texi: Use @option systematically.
6388 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6389 and Bruno Haible <bruno@clisp.org>
6391 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6393 (Integer Overflow): Mention the special case of integer division
6396 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6398 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6399 traditional shells like the Solaris one that do not use the
6400 first IFS character for assembling `$*'.
6401 Prompted by a related report from autoconf_bug@nro.ca.
6403 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6404 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6406 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6407 Mention more problems with the -e option.
6409 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6412 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6414 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6415 in URLs to improve DVI formatted output (requires texinfo 4.6).
6416 (System Services, Systemology, Shellology): Likewise.
6417 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6420 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6422 (Runtime): Fix macro argument names to match description:
6423 `action-if-found' -> `action-if-true' and similarly.
6424 (Obsolete Macros): Likewise.
6425 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6426 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6427 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6429 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6431 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6434 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6437 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6439 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6440 /bin/sh set unsorted output.
6441 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

6447 (Integer Overflow, Null Pointers, Buffer Overruns):
6448 (Floating Point Portability, Exiting Portably): New sections.
6449 (Writing Test Programs): Fix some langauge. Recommend exiting
6450 with status 1, not merely nonzero. Clarify exit declaration.
6451 (Run Time): Move C exit status stuff to new Exiting Portably section.
6452 (Systemology): Mention Posix and levenez. Update v7 reference.
6453 (Portable Shell): Mention the Posix shell.
6455 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6457 * bin/autoconf.as (me): Replace by as_me.
6459 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6461 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6462 since as_me isn't set yet.
6464 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6466 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6467 a few minor bugs in this area.
6469 * doc/autoconf.texi (Programming in M4sh): Comment out the
6470 documentation of AS_BASENAME, for now.
6471 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6472 (Limitations of Builtins) <basename>: Do not refer to
6474 * bin/autoconf.as (me): Don't use AS_BASENAME.
6475 (dir): Remove the unused variable.
6476 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6477 AS_DETECT_REQUIRED. All uses changed.
6478 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6480 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6481 (AS_BASENAME): Use "basename --" to protect against leading "-".

6483 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6484 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6485 (_AS_DIRNAME_PREPARE): Likewise.
6486 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6487 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6488 (AS_DIRNAME): Use "dirname --".
6490 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6492 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6493 of "run time" and "run-time" changed to "runtime", for consistency.
6494 * lib/autoconf/fortran.m4: Likewise (in comment).
6495 * lib/autoconf/functions.m4: Likewise.
6496 * lib/autoconf/general.m4: Likewise.
6497 * lib/autoconf/headers.m4: Likewise.
6499 * doc/autoconf.texi (Run Time): Document the exit status situation
6500 with more accuracy and detail.
6502 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6504 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6505 Archive is not officially `GNU' any more. Update URL.
6506 (Defining Directories): Likewise
6507 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6509 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6511 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6512 newline from the `trap' code to finish `config.log'; the NetBSD
6513 /bin/sh resets the exit status after an empty command, as
6514 documented in doc/autoconf.texi.
6515 Reported by Dalibor Topic <robilad@kaffe.org>.
6517 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6519 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6520 Suggested by Bruno Haible.
6522 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6524 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6525 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6526 Instead, just list the shells that we know work.
6527 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6528 changed. Be more cautious about the _cv_ variable.
6529 * tests/tools.at (Syntax of the shell scripts): Check the
6530 _cv_ variable once, at first, to avoid an internal autoconf error
6531 when sh -n does not work.
6533 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6535 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6537 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6539 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6540 use ">&-" since we're only 99.999% sure that this is portable,
6541 and since the MinGW bug is fixed in a different way.
6542 * lib/autotest/general.m4 (AT_INIT): Likewise.
6544 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6546 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6547 before opening config.log, to avoid hitting a bug on MinGW.
6549 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6551 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6552 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6553 This works around a MinGW bug reported by Eric Paire.
6554 Make sure that all writes to the log file append to it,
6555 rather than possibly losing data.
6556 * lib/autotest/general.m4 (AT_INIT): Likewise.
6558 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6560 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6563 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6567 * configure.ac (AC_INIT): Bump to 2.59d.
6569 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6573 * Makefile.maint (news-date-check): Do not require a leading `*'
6574 before the release date in NEWS.
6576 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6577 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6579 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6580 the instantiated file do not contain the string 'datarootdir'
6581 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6582 @mandir@, replace the reference '${datarootdir}' by the value.
6583 * tests/torture.at (datarootdir workaround): New test.
6584 * NEWS: Advertise this temporary fixup.
6585 Based on a patch by Bruno Haible, reported and analyzed by
6586 Paul Eggert and Noah Misch.
6588 2006-04-12 Eric Blake <ebb9@byu.net>
6590 * tests/autotest.at (Debugging a failed test): Fix comment.
6592 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6594 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6595 all the changes since 2006-04-07.
6597 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6599 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6600 succeeded, but `ln -s file dir' failed, take care to remove the
6601 leftover target before the next test, to prevent its spurious
6602 failure; also make sure `ln file dir' works before selecting it.
6603 Thanks to Keith Marshall for pointing this out.
6606 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6607 assignments in `at_debug_args', so that we put them correctly
6608 in the `run' script.
6609 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6610 Reported by Eric Blake.
6612 2006-04-11 Eric Blake <ebb9@byu.net>
6614 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6615 top-level tests after micro-suite has been run. Used in...
6616 (Debugging a successful test, Debugging script and environment),
6617 (Debugging a failed test): ...these new tests. The first of these
6619 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6620 macro, split out from...
6621 (AT_INIT): ...here, so that using -d also generates a run script.
6622 Document that -d inhibits top-level logging.
6623 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6624 inhibits top-level logging; debug scripts are created.
6626 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6628 * tests/autotest.at (Empty test, Empty check): New test to check it.
6630 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6633 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6635 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6636 the files if a problem appears. Make the empty *.at files
6637 read-only, too. Proposed by Ralf Wildenhues.
6639 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6641 * config/Makefile.am: Add comment to force updated Makefile.in.
6643 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6644 space only patch to this file, this patch causes the Makefile.in
6645 files that include freeze.mk to be updated, and thus have a
6646 newer time stamp again, which in turn makes a pristine CVS
6647 checkout have correct time stamps.
6649 * Makefile.maint (cvs-sv): New macro, to be used..
6650 (config.guess-url_prefix, config.sub-url_prefix)
6651 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6652 point to CVS text checkout of Gnulib files.
6653 (copyright-check): Bump current year.
6654 (announcement): Do not hard-wire `./announce-gen'.
6655 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6657 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6659 (wget_files): Update config.guess, config.sub, texinfo.tex by
6660 `wget-update', now that their URLs work again.
6662 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6664 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6665 Problem noted by Paul D. Smith.
6667 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6669 * doc/autoconf.texi: Remove unused words from word list.
6670 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6671 .x-sc_trailing_space: New files.
6673 * doc/standards.texi: Sync from gnulib.
6675 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6676 `LIBOBJDIR' as experimental.
6678 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6679 with a target directory; it's internally implemented as `cp'
6680 anyway, but since Autoconf advertises the possibility to use
6681 a target directory when LN_S is `ln -s', we need to find out.
6682 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6683 analyzed by Keith Marshall <keith.marshall@total.com>.
6687 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6689 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6690 confdefs.h as-is. In general, if it has backslash-newline or the
6691 like, then it doesn't work either to sort or to remove empty
6694 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6696 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6698 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6700 * lib/autom4te.in (Automake-preselections): Preselect
6703 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6705 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6706 apostrophe within a single-quoted string, as this is the usual
6707 tradition and is easier to read than '"'"'. Don't rely on the
6708 shell treating "$/" like '$/'. Use a more-consistent indenting
6711 2006-04-09 Eric Blake <ebb9@byu.net>
6713 * tests/autotest.at (Backquote command substitution),
6714 (Multiline backquote command substitution): Remove mistaken
6715 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6717 (Parenthetical command substitution, Multiline parenthetical
6718 command substitution): here.
6720 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6722 Import macros from gnulib (often changing their name).
6724 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6725 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
6726 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

6731 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
6732 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6733 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6734 The manual mentions Gnulib more prominently.
6735 * doc/autoconf.texi (Gnulib): New node.
6736 (Pointers): Add Gnulib URL.
6737 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6738 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6740 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6741 suggest a #define rather than a typedef for _Bool, and mention
6742 Gnulib rather than trying to substitute stdbool code.
6743 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6744 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6745 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6746 AC_STRUCT_DIRENT_D_TYPE.

6851 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6853 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6854 whether `set' quotes correctly: redirect stderr of the tested
6855 `set', and use a subshell, for Ultrix; use `sed' instead of
6856 `grep' for zsh `set' which may write binary output; match only
6857 at the beginning of a line, to avoid false positives.
6858 In order to avoid false positives by unrelated variables with
6859 multiline content, put the dump algorithm in a subshell and
6860 unset all variables containing newlines (except some which are
6861 special to the shell). Warn about cache variables that are

6910 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6911 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

7076 no longer needed) by libtool. Make it a cache check.

7854 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7855 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7856 by the function rather than ignoring it.
7857 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7858 comparing its address. Intel's interprocedural optimization was
7859 outsmarting the old heuristic. Problem reported by

7877 Stepan Kasal <kasal@ucw.cz>
7879 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7880 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7881 make its content writable before removing it. Remove an errorneous
7882 comment from the end, where the logs of the failed tests are copied
7883 to the main log file.
7885 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7887 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

7892 problems if the testsuite were running too fast.
7894 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7896 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7897 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7898 (which belong to Xt, not X itself). See Debian bug 327655.
7899 * NEWS: Mention this.
7901 2005-09-07 Stepan Kasal <kasal@ucw.cz>

7908 suggested by Ben Elliston. Handle weird characters correctly.
7910 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7912 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7913 calls, so that the final expansion of this macro is shorter.
7914 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7915 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7916 the cleanup there. Use AS_VAR_* macros, to be more general.
7917 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7919 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7921 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7939 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7941 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7942 in the example. Reported by Bruno Haible.
7943 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7944 "if $undefined_var;" succeeds with my shell.
7946 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7947 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7948 but change the m4_divert_text to m4_divert_once.
7950 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7952 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7953 Work around bug in Solaris /usr/xpg4/bin/awk.
7954 The bug is present in at least Solaris 8 through 10.
7956 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7958 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7959 some evil values and relying on the fact that $* concatenates the
7960 parameters by the first character from IFS.

7966 first header appears, define AH_HEADER.
7967 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7968 Update limitations about when to call AC_CONFIG_HEADERS.
7969 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7970 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7971 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7972 ``Configuration Actions''; fix their index entries.
7974 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7975 options correctly. Process N-M as M-N if M is smaller than N.
7976 Process ranges correctly so that N-N will run only N.
7977 Sort and uniquify the tests that will be run. If there is more
7978 than one test, reinsert the banners for the tests.
7979 * tests/autotest.at (Keywords): Unmark XFAIL.
7981 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7983 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7984 before passing the macro name to AH_TEMPLATE.
7986 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7987 now opens log after option processing; in particular, --version
7988 and --help do not touch config.log.

8005 Prepend to LIBS, not append, in examples.
8007 2005-08-16 Stepan Kasal <kasal@ucw.cz>
8009 When building in place, set srcdir="."; suggested by Tim Van Holder.
8011 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
8012 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
8013 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
8014 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
8015 does not mean "no --srcdir option".
8017 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8019 * tests/autoscan.at (autoscan): New file.
8020 * tests/suite.at: Use it.

8028 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8029 add "2>&1"; gzip 1.2.4 prints help on stderr.
8031 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8033 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8034 was pushdef'ed twice while popped only once. Push it only once.
8035 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8037 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8039 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

8044 * Makefile.maint: Update from Bison.
8046 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8047 "<tab>" in comment, so that the point is understandable.
8049 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8051 Rewrite substantial part of lib/autoconf/status.m4.
8052 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8053 and CONFIG_COMMANDS are not processed in four separate loops.
8054 Instead, there is one main loop. This alows that the common code
8055 is expanded only once, thus config.status (and configure) is smaller.
8057 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8058 the AC_LIST_FILES and cousins macros are no longer used.
8060 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8061 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8062 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8063 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8064 contain the initialization, nor the for loop, nor the associated
8065 commands; all these go to ...
8066 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8067 _AC_OUTPUT_CONFIG_STATUS.
8068 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8069 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8070 (_AC_OUTPUT_FILE): The creation of the sed script ...
8071 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8072 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8073 _AC_OUTPUT_MAIN_LOOP.
8074 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8075 _AC_CONFIG_COMMANDS): Use ...
8076 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8077 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8078 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8079 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8080 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8081 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8083 (_AC_CONFIG_UNIQUE): Update.
8084 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8085 Replaced by this ...
8086 (_AC_LIST_TAGS): ... new common macro.
8087 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8088 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8089 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8090 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8091 this didn't belong to the `config commands' section.
8092 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8093 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8094 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8095 to the `config commands' section either.
8096 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8097 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8099 ... and many changes to the comments nearby.
8101 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8102 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8103 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8104 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8105 (#define header templates): The comment at the top of the generated
8106 header now includes the name(s) of the source file(s).
8108 Several unrelated small changes:
8110 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8111 parameter to AC_DIAGNOSE.
8112 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8113 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8114 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8115 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8117 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8118 in AC_OUTPUT doesn't double-quote it either.
8119 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8122 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8124 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8125 versions of Portland Group compiler produce single- and double-quoted
8126 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8127 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8129 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8131 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8132 This is a corrected version of yesterday's patch.
8134 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8136 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8137 path, too; insert a "===" to emphasize the line.
8139 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8140 ac_cv_build_alias to ac_build_alias.
8141 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8143 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8144 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8145 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8146 (AC_ARG_VAR): ... here.
8147 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and

8151 for loop, instead of expanding all commands, or, OTOH, complicated
8152 processing of output of "set".
8153 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8154 variable names in new macro...

8214 configure_input, top_builddir, srcdir, etc.
8215 * lib/autotest/general.m4 (AT_INIT): Likewise, for

8287 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

8307 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8308 variable into diagnostic. Make the diagnostic an error, not a warning,
8309 because we really don't support spaces and suchlike in dir names.
8310 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8311 Don't worry about backslashes in srcdir; it can't happen now.

8355 * doc/autoconf.texi:
8356 Don't mention Solaris versions so much, if a
8357 problem is common to all extant versions of Solaris. Say "SunOS
8358 4" instead of "SunOS" for SunOS 4.
8359 (awk): Mention more of the limitations of traditional Awk.

8402 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8403 -u, since it outputs chatter if the input files are the same.
8404 Problem reported by Ralf Menzel.
8406 2005-06-08 Derek Price <derek@ximbiot.com>
8408 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8409 renaming them since they are about to be redefined anyhow.
8411 2005-06-08 Derek Price <derek@ximbiot.com>
8413 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8414 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8415 Move m4_undefine to alphabetical order.

8420 * doc/autoconf.texi (Introduction): Likewise.
8421 Reword to avoid some formatting glitches.
8422 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

8424 Redo example output tp match current CVS snapshot.
8425 Use @example.org in email addresses when the examples
8426 might get inadvertently cut-and-pasted into user code.
8427 Remove example of autom4te usage that doesn't seem to work now.
8428 Use modern AC_INIT (except when the example is meant to be
8429 shown with Autoconf 2.13).
8430 Update ksh info for Solaris 9 and later.
8432 Modernize description of Automake versions a bit.

8443 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8444 Tru64 ksh pattern matching bug. Reported against Libtool by
8445 Albert Chin <libtool@mlists.thewrittenword.com> and
8446 Nicolas Joly <njoly@pasteur.fr>.
8448 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8450 m4_cdr of one-member list was [[]] (one-member list containing an
8451 empty string) instead of [] (an empty list. Callers were skewed to
8452 match this misbehaviour. As a consequence of this:
8453 - m4_foreach([x], [], [foo]) expanded to `foo', while
8454 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8455 This bug has been fixed:
8457 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8458 expand to an empty string; print error msg if called without
8460 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8461 misbehaviour; handle [] and [[]] correctly.

8471 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8472 swallow records with more than 99 fields.
8473 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8474 parse the long line.
8476 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8478 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

8513 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may

8518 commands can be put in a sed script portably.

8568 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8569 (ac_top_builddir): ... this ...

8588 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8589 argument to m4_foreach. I guess it was necessary in the past,

8673 * doc/autoconf.texi (Autoconf Language): Be more precise about
8674 quoting rules. Problems noted by Stepan Kasal.
8675 Also, throughout this document, be more careful about white space.
8676 "blank", "white space", and "space" all have different meanings
8677 and we should be careful to say what we mean.

8688 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8690 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8692 * doc/autoconf.texi (Generic Functions): Typos.
8694 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8696 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8697 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8698 set by latest automake.
8700 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8702 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"

8713 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8716 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8717 by AC_DEFINE; it was a mistake.
8718 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8720 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8722 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8724 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8726 * doc/autoconf.texi (External Software): Quadrigraphs are not
8727 processed correctly in AS_HELP_STRING; avoid this in the examples.
8728 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8729 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8730 comment and reduce m4_default([foo], []) to [foo].
8731 (m4_strip): Update the explanation.
8733 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8735 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8736 Remove core.conftest.* too; it's generated by Tru64 5.1.
8737 Problem reported by Jennis Pruett.
8738 * lib/autoconf/functions.m4
8739 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8740 Don't bother to remove core files; AC_RUN_IFELSE should do that

8762 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8764 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8765 as well as configure.in. Problem reported by Gregorio Guidi.
8767 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8769 * doc/autoconf.texi (Particular Functions): Use gnulib's current

8787 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8788 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8789 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8790 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8791 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8793 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8795 * NEWS: The configure command now warns you if you attempt to use
8796 a directory whose name contains a special character like space,
8798 * doc/autoconf.texi (Installation Directory Variables): Allow
8799 "," in file names. Do not use \@; it's not a portable regexp.
8800 * bin/Makefile.am (edit): Likewise.
8801 * lib/Makefile.am (edit): Likewise.
8802 * tests/Makefile.am (edit): Likewise.
8803 * tests/semantics.at: Likewise.
8804 * tests/torture.at: Likewise.
8805 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8806 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8807 * doc/autoconf.texi (File System Conventions): Warn about
8808 unportable file names.
8809 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8811 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8812 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8813 ac_pwd, and quote srcdir.
8814 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8816 * doc/autoconf.texi: Fix some systematic formatting problems.
8817 ".)" needs a following @: if not at the end of a sentence, and
8818 similarly for "!)". "etc." should be preceded by a comma.
8819 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8821 2005-03-22 Bruno Haible <bruno@clisp.org>
8823 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8824 argument is often called 'build-aux'.
8826 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8828 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8829 macro AC_TRY_LINK is obsolete.
8830 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8833 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8835 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8836 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8837 from a Common Lisp's `cl'.
8838 (AC_PROG_CXX): Behave according to the documentation: don't
8839 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8840 make the variable CCC precious; use `cl.exe', not `cl'.
8842 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8843 Alexandre Duret-Lutz <adl@gnu.org>
8845 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8846 /dev/null, as "configure" shouldn't read stdin, and this insulates
8847 us from problems (e.g., when testing for "cl"). Also, do this
8848 redirection before invoking "hostname" or "uname", and keep the
8849 original input stream available via...
8850 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8851 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8852 bother with "</dev/null" since it's now done at the top of
8854 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8855 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

8861 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8863 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8864 newline if neither \c nor -n work, as that would output two
8865 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8867 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8869 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8870 This causes that any required macros inside will get before the if.
8871 * doc/autoconf.texi (autom4te.cache): A typo.
8873 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8875 Undo previous change, except keep the change to
8876 lib/autoconf/programs.m4 that replaced grep with shell
8877 pattern-matching. This is because net-snmp configure reads stdin.
8878 Reported by Noah Misch.
8880 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8882 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8883 from /dev/null, as "configure" shouldn't read stdin, and this
8884 insulates us from problems (e.g., when testing for "cl").
8885 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8886 before invoking "hostname" or "uname".
8887 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8888 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8889 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8890 "</dev/null" since it's now done at the top of 'configure'.
8891 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8892 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8893 Also, replace grep with shell pattern-matching, to save a process.
8895 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8897 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8898 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8899 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8902 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8904 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8905 grep -q isn't portable. Improve grep -s explanation.
8906 Problem reported by Dan Manthey.
8908 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8910 * doc/autoconf.texi (Special Shell Variables): Clarify
8911 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8913 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8915 * doc/autoconf.texi: Use @acronym for DJGPP.
8916 Fix some @code's that should have been @env's, and vice versa.
8917 Sort environment variable names.
8918 Mention that shells no longer inherit IFS.
8919 Don't recommend PATH_SEPARATOR=';' so strongly.
8920 Mention that $RANDOM might expand to the empty string.
8921 "symlink" and "soft link" -> "symbolic link".
8922 Improve mktemp description (reported by Bruno Haible).
8924 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8926 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8927 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8929 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8932 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8934 * NEWS: Mention AT_COPYRIGHT.
8936 * tests/local.at (AT_CMP): Use diff directly on input files rather
8939 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8940 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8942 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8943 and Paul Eggert <eggert@cs.ucla.edu>
8945 * tests/autotest.at (Empty test suite): New test.
8946 * tests/torture.at (Substitute and define special characters)
8947 (Substitute a 2000-byte string, Define to a 2000-byte string)
8948 (Substitute a newline, Define a newline): New tests.
8950 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8952 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.

8955 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8956 (Standard regular expressions): New test.
8957 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8958 excess test name quoting.
8959 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8960 CPPFLAGS to `configure' instead of setting it in `configure'.
8962 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8963 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8966 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8967 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

8973 (AT_CONFIG_CMP): New macro.
8974 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8975 * tests/c.at (Extensions): Do not exit early.
8976 * tests/atlocal.in: Inherit $GREP.
8978 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8979 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8981 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8982 (AC_COPYRIGHT): Factor header comment portion out and move into...

8995 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8997 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8998 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
9000 Try not to generated lines of unlimited length, as POSIX places a
9001 2047-byte limit on line length of portable text files.
9002 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
9003 Use newline as a separator, not space.

9012 are restored after function return.
9014 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
9016 * doc/autoconf.texi (Special Shell Variables): Mention _,
9017 BIN_SH, DUALCASE. Say that variables other than "status" are safe
9018 if they contain a lower-case letter. The DUALCASE problem was
9019 reported by Ralf Wildenhues.
9021 * bin/autoconf.as: Don't exit with status 0 after write failure
9022 with --help or --version.
9023 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

9034 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
9036 * man/Makefile.am (.x.1): Go back to the simple solution, but take
9037 care to echo the commands, so the user knows what's going on.
9038 Modified from a suggestion by Stepan Kasal.
9040 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
9041 with a cross reference. Derived from a suggestion by Bruce Korb.

9048 Based on a proposed patch by Ralf Wildenhues.
9050 * man/Makefile.am (.x.1): Make sure the required generated files
9051 are up to date. Problem and original solution proposed by Stepan Kasal.
9052 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
9053 implicit-man-prerequisites): New rules, used by the above.

9061 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9062 Update the long comment explaining it.
9064 m4_require no longer writes an ``is required by'' line to the
9065 execution stack. It contains only one bit of non-redundant
9066 information: that the macro was required, not called. And even
9067 this bit is useless in most situations: have you ever met a macro
9068 which both calls and requires the same macro?
9070 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9071 (_m4_defun_pro_outer): ... only via this macro, for the outermost

9076 execution stack; slightly improve the out-of-a-defun error message.
9077 (_m4_divert_grow): New macro, counter for the temporary diversions.
9078 (_m4_require_call): Use it.
9079 * tests/m4sugar.at (m4_require): Expect output without the
9080 ``is required by'' messages.
9082 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

9176 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
9177 stored in _m4_divert_diversion or _m4_divert_dump.
9178 (m4_divert_pop): When the parameter is given, compare the symbolic
9179 name with the last diversion pushed on the stack. Previously, the
9180 current diversion was compared with the numeric value of the
9181 diversion given as the parameter.
9182 (m4_require): If the macro hasn't been expanded yet, call ...
9183 (_m4_require_call): this new macro.

9488 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
9490 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9491 "char c = '\200';" rather than "char c = 0x80;" as the
9492 latter doesn't conform to the strict C standard due to
9493 overflow on signed char hosts.
9495 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
9496 to -qlanglvl=ansi. We don't want to disable extensions.
9498 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>

9556 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9557 the $1_found variable, don't test whether the file is executable;

9594 * doc/autoconf.texi (auindex): New macro.
9595 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.

9604 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9605 readable; it's not true in OS/2-emx.

9609 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9610 "/usr/include", clear ac_x_includes instead of leaving it as "no"

9641 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9642 texinfo.tex for now (done by hand now).
9643 * Makefile.maint (wget_files, cvs_files):
9644 Remove ansi2knr.c; nobody uses it.
9645 (ansi2knr.c-url_prefix): Remove.

9649 * doc/autoconf.texi: Update URLs, some of which went stale.
9650 Use @uref rather than @href.
9652 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9653 handle "--" as per POSIX. Suggested by Paul Pogonyshev.

9656 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9657 doc/fdl.texi, doc/standards.texi: Sync with master copy.

9668 to be consistent with the terminology of the GNU coding standards.
9670 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9672 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9673 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9674 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9675 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9677 More fixes to support spaces in the name of the build directory.
9678 This isn't a complete fix but it's an improvement.
9680 * bin/autoconf.as (autom4te_options): New var.
9681 Use it instead of appending to AUTOM4TE, so that we can allow
9682 spaces in the build directory's absolute name.
9683 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9684 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9685 AT_CHECK_NOESCAPE): Likewise.
9686 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

9698 and isnan. From a suggestion by Kevin Ryde.
9700 * lib/Autom4te/General.pm (END): Return correct exit status even
9701 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9703 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9705 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9706 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9707 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9709 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9711 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9712 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9713 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9714 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9715 * lib/autom4te.in (Automake-preselections): Preselect
9716 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9718 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9720 * lib/autom4te.in (Automake-preselections): Preselect
9721 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

9734 with pdksh, too. Problem reported by Patrick Welche via
9736 * doc/autoconf.texi (Shellology): Note that set -o posix is
9737 useful for pkdsh, too.
9739 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9741 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9742 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9743 Don't fail if ENV or BASH_ENV is readonly.
9744 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9745 etc. are read only. Problem reported by Ludovic Courtes.
9747 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9749 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9750 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9753 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9755 * doc/autoconf.texi (File System Conventions): Warn about
9756 names like "aux". Problem reported by Eric Blake.
9758 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9759 by zero instead of array size, so that we can use any arithmetic
9760 constant expression (instead of requiring an integer constant
9761 expression). This allows us to test expressions like DBL_MAX <
9762 LDBL_MAX, which didn't conform to the C standard using the old
9764 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9765 now that we can do floating-point tests at compile time.
9767 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9769 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9770 and LDBL_EPSILON, as the resulting expression isn't an
9771 integer constant expression and violates the C standard.
9772 Problem reported by Nelson H. F. Beebe. Also, check
9773 for "L" suffix, and check that long double doesn't have
9774 worse range or precision than double, that mixed-mode
9775 arithmetic doesn't generate a diagnostic, that double
9776 constants fit in long double.
9778 2004-06-03 Kevin Ryde <user42@zip.com.au>
9780 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9781 malloc(0) and realloc(NULL,size).
9783 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9786 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9788 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9789 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9792 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9794 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9795 can be rewritten using if-then-else. Suggested by Bruno Haible.
9797 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9799 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9800 Problem reported by Stepan Kasal.
9802 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9804 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9805 change). Patch reported by Ralf Wildenhues in
9806 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9808 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9809 function F exists if the compiler and linker let you compile an
9810 expression like (F != 0). Recent versions of GCC optimize away
9811 the reference to F in that case, since every function address must
9812 be nonzero, so the link succeeds even if F does not exist.
9813 Problem reported by Manu in
9814 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9816 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9817 "Unix". Many uses changed.

9829 referencing AC_FUNC_STRERROR_R.
9831 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9832 note pessimistic assumption when cross compiling.
9834 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9836 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9837 (until 2004) invoked subcommands with sh -e, contra POSIX.
9838 Reported by Kevin Ryde.
9840 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9842 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9843 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9844 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9845 `test -f " /usr/bin/grep"', which _always_ failed.
9846 (AC_PROG_SED): Ditto bogus PATH fix.
9847 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9848 requires that grep correctly supports _multiple_ `-e' options, rather
9849 than stating only that grep should accept `-e'.
9851 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9853 Port to C99, which requires that 'exit' be declared.
9855 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9856 to ensure that stdlib.h is included.
9857 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9858 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9859 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9860 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9861 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9862 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9863 when using 'exit' in a test; C99 requires that 'exit' be declared.
9865 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9867 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9868 now prefers 'grep' implementations that accept -e.
9869 (Limitations of Usual Tools): Describe problems of traditional
9870 egrep and fgrep with long input lines, and of traditional grep
9872 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9873 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9874 All callers changed. Append /usr/xpg4/bin to the PATH, for
9876 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9877 the user with complaints about multiple -e options.
9878 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9879 Define it with AC_PROG_GREP.
9880 * configure.ac (AC_PROG_GREP): Add.
9881 * lib/freeze.mk (GREP): New macro.
9883 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9885 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9886 a possible candidate only after all others fail, rather than
9887 consulting it first. This improves backward compatibility by
9888 better reflecting the way shell selection occurred in previous
9889 versions of Autoconf, and should help to avoid triggering latent
9890 problems in other packages, such as the one in Automake where zsh
9891 is not handled robustly:
9892 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9893 Although it is not Autoconf's responsibility to work around
9894 problems in Automake, it nevertheless makes sense to avoid
9895 introducing unnecessary incompatibilites.
9897 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9898 Gary V. Vaughan <gary@gnu.org>
9900 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9901 how deeply nested we are when a suitable tool is found, set the
9902 ac_path_TOOL_found flag.
9903 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9904 nested we are in this macro. Break out of all 3 nested loops if
9905 ac_path_TOOL_found is set.
9907 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9909 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9910 of the _AS_PATH_WALK loop too if GNU flavor is found.
9912 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9914 * doc/autoconf.texi (Limitations of Make): Update documentation
9915 for `$<'. New entry `Long lines', based on a report from Simon
9916 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9917 paragraph about DJGPP, based on a mail from Richard Dawe.
9919 2004-04-20 Paul Eggert <eggert@twinsun.com>
9921 * tests/c.at (C keywords): Don't assume that GCC supports
9922 "restrict" and "inline", as sufficiently-old GCC versions do not
9923 (also, GCC configured to be in pedantic C89 mode does not).
9924 Problem reported by Sumit Pandya in:
9925 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9927 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9928 consider -g to work if it generates warnings when plain compiles
9929 don't. Problem reported by Braden McDaniel in:
9930 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9932 * doc/autoconf.texi (Slashes): New section, to document a problem
9933 reported by Jim Meyering in:
9934 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9936 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9937 linker output files before linking, to work around IRIX 6 linker bug.
9938 Problem reported by Rainer Orth in:
9939 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9941 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9943 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9944 best tool so far counter rely on the tool path variable name to
9945 avoid checks for one tool being affected by the results of running
9946 the length check on a previous tool.
9948 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9949 match expression argument, as different greps have different
9950 regular expression flavours.
9951 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9953 (AC_PROG_EGREP): Pass 'EGREP$'.
9954 (AC_PROG_GREP): Pass 'GREP$'.
9956 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9958 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9959 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9961 2004-03-29 Paul Eggert <eggert@twinsun.com>
9963 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9964 Types, Specific Compiler Characteristics, System Services,
9965 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9966 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9967 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9968 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

10035 * NEWS: Document these changes.
10037 * doc/autoconf.texi: Avoid macros with unbraced arguments,

10077 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10078 $(m4sh_m4f_dependencies); this removes a FIXME.
10079 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10080 (MAINTAINERCLEANFILES): Split into pieces,
10081 one per related section. Add $(srcdir)/wrapper.in.

10086 AC_SUBST provides no portable way to escape literal newlines.
10088 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10089 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10090 Darwin uses -lcrt2.o and there's little point to cataloging all
10091 the system variants. Partial fix reported by Andreas Waechter in:

10117 Paul Eggert <eggert@twinsun.com>
10119 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
10120 (AS_INIT): Output shell initialization there. Removed optional
10121 parameter. Expand _AS_SHELL_FN_SPY.

10134 trigger the bash bug anymore.
10135 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10136 use AS_INIT_WITH_SHELL_FN.
10137 * bin/autoconf.in, tests/wrapper.in: Regenerated.

10167 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

10169 the 2003-05-22 change, which removed the older years from the list.
10170 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

10183 _AC_PROG_GREP, and AC_PROG_SED.
10184 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10185 longest input length accepted by a command.

10214 2004-01-26 Paul Eggert <eggert@twinsun.com>
10216 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10217 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10218 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10219 not <inttypes.h>. Problem reported by Tim Mooney in
10220 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10221 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10224 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10225 otherwise "make check" fails because it forbids cmp (I guess
10226 because cmp treats files as binary on DOS-like systems).
10228 * tests/mktests.sh: Update copyright date to 2004, since some tests
10229 have changed in 2004.
10231 2004-01-23 Gary V. Vaughan <gary@gnu.org>

10234 non-truncating sed or gsed program in PATH.
10235 * tests/acprograms.at: Add it.

10239 2004-01-15 Paul Eggert <eggert@twinsun.com>
10241 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10242 -std1 disables some useful extensions on Tru64. Problem reported
10243 by N. Lichtmaier in
10244 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10246 2004-01-14 Paul Eggert <eggert@twinsun.com>
10248 * doc/autoconf.texi (Programming in M4sh): Document that
10249 AS_MKDIR_P succeeds if the destination is a symbolic link
10250 to an existing directory.
10251 (Limitations of Usual Tools): Note that mkdir -p might not
10252 succeed on symlinks to directories.
10254 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10256 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10257 * bin/autoheader.in: Grammar fix in message.
10258 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10259 Test for dir before calling mkdir -p. (trivial changes)

10266 2004-01-10 Jim Meyering <jim@meyering.net>
10268 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10270 2004-01-09 Paul Eggert <eggert@twinsun.com>
10272 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10273 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10274 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10275 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10276 AC_COMPILE_IFELSE, since we now assume our caller invokes
10277 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10278 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10279 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10280 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10282 2004-01-07 Paul Eggert <eggert@twinsun.com>
10284 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10285 `"'...'"`, as it's confusing (and I suspect it may not work on
10286 some platforms). The code was incorrect anyway, as it assumed
10287 that \$ evaluated to itself in that context. Reported by
10288 Alexandre Duret-Lutz.
10290 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10292 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10293 and _LT_AC_TAGCONFIG.
10295 2004-01-06 Paul Eggert <eggert@twinsun.com>
10297 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10298 example, and add more examples. Reported by Eric Sunshine.

10320 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10321 Use "rm -f" to remove conftest.sed, not plain "rm".
10322 Bug reported by David Relson in
10323 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10325 * Makefile.am (autom4te-update):
10326 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

10342 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10343 -c -o might not work. From a suggestion by Kevin Ryde.
10344 (C Compiler, Generating Sources, Limitations
10345 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10346 Don't put '-o' after non-options, as POSIX doesn't allow this.
10347 Mention that cc's name might be gcc or c89 or whatever.
10349 2004-01-04 Kevin Ryde <user42@zip.com.au>
10351 * doc/autoconf.texi: Add various further index entries.

10356 Fix typo: mkdir without umask arg.
10358 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10360 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10361 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

10363 explanation clearer.

10374 * tests/atlocal.in: Store the result here.
10375 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

10377 of explicitly testing.
10378 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10379 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10380 * tests/tools.at (Syntax of the shell scripts): Simplify

10465 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10466 than $target since the latter is not usual, add guidelines on when to

10648 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10649 -mGLOB_options_string stuff for Intel ifc, which can cause

10674 cache variable instead of $G77 to decide whether to include -O2,
10675 since $G77 is specific to Fortran 77.

10685 arguments so that it can be used with syntax identical to
10686 AC_PROG_F77, and so that we can more easily decide to
10687 remove/deprecate the DIALECT optional argument in the future if it
10688 proves troublesome.
10689 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10690 non-freeform-supporting compilers. Document freeform flags.
10692 2003-10-03 Akim Demaille <akim@epita.fr>

10755 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10756 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

10761 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10762 directory for AC_CONFIG_COMMANDS' first argument exists.
10763 This makes valid the invocation of _AC_SRCPATH that follows.
10764 Reported by Eric Sunshine.

10788 The test suite are sometimes assigning timings incorrectly.
10789 Reported by Henk Krus.
10790 Diagnosed by Nicolas Joly.
10792 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10794 Instead of making AT_help a sequence of assignments to grow
10795 $at_help_all, just make AT_help_all be the growing contents of
10796 $at_help_all, and make a single assignment in...
10798 (at_times_skip): Flip the meaning and rename as...
10799 (at_times_p): this.

10810 (ifnames): chmod -w.
10811 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10812 executables, not bin/ executables! Otherwise all the magic needed
10813 to find non installed files is turned off. This caused a failure
10814 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10815 as found in its environment (sent by tests/autoreconf): pointing
10816 to bin/autom4te that could not find its files.
10817 * tests/mktests.sh: Force the replacement of generated files, for
10818 the sake of "mv" program that are interactive when overwriting a

10871 and AC_FC_FREEFORM.

10913 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10915 Add support for newer Fortran dialects. The F77 interface is
10916 unchanged, and continues to support Fortran 77. New FC macros
10917 correspond to all the old F77 macros, with output variables FC,

11021 * bin/autom4te.in: Adjust to output the call stack.

11047 2003-08-21 Akim Demaille <akim@epita.fr>
11049 First stab at preserving warnings between calls to autom4te,
11050 including when the cache is used.
11052 There are still several issues: (i) there are too many runs of m4
11053 (one for include, one for warnings, and some more), (ii) warnings
11054 spreading on several lines are not handled gracefully, (iii) the
11055 code meant to have the call stack display for errors does not work
11056 (its handling should move from m4 to autom4te).
11058 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11060 (@preselect): Add m4_warn.
11061 ($exit_status): Remove, use $exit_code.
11062 ($help): Use Autom4te::ChannelDefs::usage.
11063 (&handle_m4): No longer define the m4_warnings.
11064 At each run, extract and report the warnings.
11065 Always cache the result, including if the exit status is on
11066 failure, since if nothing changes, we should result in the same
11067 failure, hence we can use the cache.
11068 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11069 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11071 (m4_warn): Redefine as a do-nothing: it is its invocation that
11072 matters, as warnings are now reported via traces.
11073 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11074 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11075 the latter reveals calls to the former.
11079 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

11101 (&catfile): Remove.
11102 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,

11108 Reported by Alexandre Duret-Lutz.

11112 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11113 * bin/autom4te: Adjust.
11114 In particular, be Autoconf tools are really silent when properly
11115 working, bind the verbosity of the 'note' channel to $verbose.
11116 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11117 (&xsystem, &contents): Remove, since they are exported by...

11238 2003-06-23 Akim Demaille <akim@epita.fr>
11240 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11241 not all of them. This fixes 1. the fact that when testing
11242 Autoconf there are many many config.log, 2. the incorrect use of
11243 top_srcdir to find config.log.
11244 Don't mix the detailed output of failed test with the summary of
11245 failures. Rather, append detailed log afterwards.
11247 2003-06-23 Akim Demaille <akim@epita.fr>
11249 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

11336 (xsystem): Reset $! before running system, and check it afterward.
11337 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11338 63 for version mismatches.
11340 2003-05-23 Akim Demaille <akim@epita.fr>
11342 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of

11362 Paul Eggert <eggert@twinsun.com>
11364 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11365 Remove `#include <stdlib.h>' from the list; we should never
11366 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11367 resulting namespace pollution would cause other tests to fail.
11368 Configure scripts run with some older versions of g++ and HP's
11369 aCC would fail due to such an #include. Problems reported by
11370 Matthew Mueller in <http://bugs.debian.org/120704> and by
11372 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11373 In the test, use the test declaration before including <stdlib.h>,
11374 as that's closer to how it'll be used.

11378 * doc/autoconf.texi (Header Portability): ucred.h.
11381 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11383 Overhaul Autotest's logging: generate separate log files
11384 in testsuite.dir/NNN/testsuite.log, and append them to
11385 testsuite.log instead of re-running the test verbosely.
11387 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11388 file descriptor, write 0 to at_status_file instead of setting
11389 at_status=0, initialize some new variables (at_status_file,
11390 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11391 to rerun the tests, instead append the at_group_log to the

11527 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11528 by aclocal.m4 is changed it might require the importing of another
11529 m4 extension file, i.e., aclocal must be run.

11802 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11803 defined, to support freestanding compilers. This should fix the
11804 bug reported by Momchil Velkov in

11807 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

11843 * Makefile.maint: Sync with Bison, i.e.:
11844 (po-check): Scan .l and .y files instead of the

11903 Reported by Ezra Peisach.
11905 2002-11-05 Akim Demaille <akim@epita.fr>
11907 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11909 We _have_ to stop using the old compatibility scheme that tried to
11910 avoid useless backslashes because Libtool 1.4.3 contains a
11911 AC_DEFINE([error_t], [int],
11912 [Define to a type to use for \`error_t' if it is not
11913 otherwise available.])
11914 We _have_ to quote the single quote and backslashes with \. The
11915 old compatibility scheme saw that ` was backslashed, and therefore
11916 did not quote the single quote. Hence before this patch, Autoconf
11917 was not compatible with Libtool.

12308 Reported by Alexandre Duret-Lutz.
12310 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12371 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12372 aclocal invocation, as Gettext macros might not be visible to

12380 Work around problems found when POSIXLY_CORRECT=1 is set.
12381 None of this seems to have anything to do with POSIX, really,
12382 but it's how Perl getopt works.
12383 * bin/autom4te.in (parse_args): Configure GetOpt with
12385 * doc/autoconf.texi (Invoking autom4te):
12386 --warning -> --warnings.
12387 * lib/autom4te.in: --warning -> --warnings.
12389 2002-09-28 Akim Demaille <akim@epita.fr>
12391 * doc/autoconf.texi (autom4te.cache): New section.
12393 2002-09-28 Akim Demaille <akim@epita.fr>

12403 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12404 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12406 2002-09-28 Akim Demaille <akim@epita.fr>
12408 * tests/torture.at (Configuring subdirectories): Be robust to
12409 users who use config.site to require for a cache: in this case,
12410 the two last configure runs, using two different sets of
12411 arguments, trigger a legitimate error.
12413 2002-09-28 Akim Demaille <akim@epita.fr>
12415 * tests/m4sh.at (Functions Support, Functions and return Support):
12418 2002-09-28 Akim Demaille <akim@epita.fr>
12420 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12421 autoheader are Perl programs.
12422 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12423 (autom4te): Specify that the sources are in the $srcdir.

12431 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12432 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12433 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

12446 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12447 (.m4.m4f): Don't pass --prepend-include, since that's done by
12448 tests/autom4te itself.
12449 * lib/autoscan/Makefile.am: Include freeze.mk.
12450 (autoscan.list): New target --this file is no longer a source.
12451 (autoscan.pre): New file.
12453 2002-09-28 Akim Demaille <akim@epita.fr>
12455 * bin/autoscan.in (@kinds): Make them singular.
12457 (&init_tables): When --debug, report the list of rules to ease
12458 tracking changes in autoscan.list.
12459 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12461 2002-09-28 Akim Demaille <akim@epita.fr>
12463 * lib/autoscan/functions, lib/autoscan/headers,
12464 * lib/autoscan/identifiers, lib/autoscan/makevars,
12465 * lib/autoscan/programs: Merge into...
12466 * lib/autoscan/autoscan.list: this.
12467 * bin/autoscan.in (&init_tables): Adjust.
12469 2002-09-28 Akim Demaille <akim@epita.fr>
12471 * lib/autoscan/functions, lib/autoscan/headers,
12472 * lib/autoscan/identifiers, lib/autoscan/makevars,
12473 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12474 `functions' line is now prefixed with `function:'.
12475 * bin/autoscan.in (&init_tables): Adjust.
12477 2002-09-28 Akim Demaille <akim@epita.fr>
12479 From now on, autoscan files must always map a macro name to a
12480 word: there is no `default' macro for autoscan.
12482 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12484 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12487 2002-09-28 Akim Demaille <akim@epita.fr>
12489 * bin/autoscan.in (%c_keywords): Remove.
12490 (&used): Keep only track of the words we might be interested in.
12491 (&output_kind): It is no longer needed to look for non active
12494 2002-09-27 Akim Demaille <akim@epita.fr>
12496 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

12498 * lib/autoscan/functions: Adjust.
12499 * doc/autoconf.texi (Particular Functions): Adjust.
12501 2002-09-27 Akim Demaille <akim@epita.fr>

12505 Thanks to Bill Moseley and Paul Eggert.
12506 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12507 the tmpdir must be created.
12508 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12509 dir be in the build tree, instead of $TMPDIR.
12511 2002-09-27 Akim Demaille <akim@epita.fr>
12513 * bin/autoscan.in: Improve the comments.
12514 (&parse_args): Drop obsolete undocumented options.

12521 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12522 Reported by Ralf Corsepius.
12523 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12525 2002-09-26 Akim Demaille <akim@epita.fr>
12527 Single suffix rules and seperated dependencies are not portable.
12529 * doc/autoconf.texi (Installation Directory Variables): Update.
12530 (Limitations of Make): Some about `Single Suffix Rules and
12531 Separated Dependencies'.
12532 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12533 (ifnames, autoscan, autom4te): Un-factor into several rules.
12535 2002-09-25 Paul Eggert <eggert@twinsun.com>
12537 * BUGS (Interoperability bugs): New section. Mention libtool
12538 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12540 2002-09-24 Paul Eggert <eggert@twinsun.com>
12542 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12543 make handles suffix-rules differently from GNU make.
12545 * bin/Makefile.am (SUFFIXES, .in): Remove.
12546 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12547 Move the body of the old .in rule here.
12549 2002-09-16 Akim Demaille <akim@epita.fr>
12551 i960 compilers create `b.out' files by default.
12552 Reported by Ralf Corsepius.
12554 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12555 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12557 2002-09-13 Paul Eggert <eggert@twinsun.com>
12559 * doc/autoconf.texi (Particular Headers): Remove obsolete
12560 reference to `struct timezone' in the description of
12563 2002-09-13 Akim Demaille <akim@epita.fr>
12567 * config/config.sub, config/config.guess: Update.
12568 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12569 * Makefile.am: Adjust.
12571 2002-09-13 Akim Demaille <akim@epita.fr>
12573 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12574 reading config.log when the compiler is rejected.
12575 Suggested by Guido Draheim.
12577 2002-09-13 Akim Demaille <akim@epita.fr>
12579 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12580 (chdir_init) might hang when stat'ing mounted directories.
12581 Reported by Vance Shipley.
12583 2002-09-12 Akim Demaille <akim@epita.fr>
12585 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12588 2002-09-12 Akim Demaille <akim@epita.fr>
12590 * doc/autoconf.texi (Defining Symbols): Present two different
12591 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12592 difference between 1 argument calls, and 2-3 argument calls.
12594 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12596 * doc/autoconf.texi: Review grammar and punctuation.
12598 2002-09-11 Paul Eggert <eggert@twinsun.com>
12600 * doc/autoconf.texi: Fix minor formatting, spelling, and
12602 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12603 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12606 2002-09-11 Akim Demaille <akim@epita.fr>
12608 * doc/autoconf.texi (Questions): Rename as...
12610 (Defining Directories): New.
12612 2002-09-09 Akim Demaille <akim@epita.fr>
12614 * doc/autoconf.texi (Making testsuite Scripts): Update.
12615 Suggested by Nishio Futoshi.
12617 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12619 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12620 plain `@' is wanted.
12622 2002-09-09 Akim Demaille <akim@epita.fr>
12624 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12625 `duplicates', since the algorithm was too naive and could keep
12626 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12627 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12628 Reported by Ralf Corsepius.
12629 * tests/torture.at (Configuring subdirectories): Exercise these
12632 2002-09-09 Akim Demaille <akim@epita.fr>
12634 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12635 looking for a replacement file.
12636 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12637 directory is relative.
12638 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12639 directory definition.
12640 Reported by Andreas Schwab and Jim Meyering.
12642 2002-09-06 Akim Demaille <akim@epita.fr>
12644 * doc/autoconf.texi (Setting Output Variables): Clarify what
12645 precious variables are.
12646 Suggested by Pontus Skoeld.
12648 2002-09-05 Akim Demaille <akim@epita.fr>
12650 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12651 (ifnames, autoscan, autom4te): Since we don't only depend on
12652 configure.ac variables (such as VERSION etc.), but also on prefix
12653 and so forth, depend on Makefile, not configure.ac.
12654 Reported by Alexandre Duret-Lutz.
12655 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12657 2002-09-05 Kevin Ryde <user42@zip.com.au>
12659 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12660 doesn't seem to be confined to ia64, just say "some versions".
12662 2002-09-04 Akim Demaille <akim@epita.fr>
12664 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12666 * Makefile.am (maintainer-clean-local): Remove.
12667 (MAINTAINERCLEANFILES): Remove COPYING.
12669 2002-09-03 Paul Eggert <eggert@twinsun.com>
12671 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12672 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12675 2002-09-03 Akim Demaille <akim@epita.fr>
12677 * configure.ac: Bump to 2.53d.
12678 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12679 as of today, on Automake's team suggestion.
12681 2002-09-03 Akim Demaille <akim@epita.fr>
12685 2002-09-02 Akim Demaille <akim@epita.fr>
12687 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12689 * configure.ac: Disable SITE_MACRO_DIR.
12691 2002-09-02 Jim Meyering <meyering@lucent.com>
12693 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12694 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12695 Also, tweak grammar: s/make sure to/be sure to/.
12697 2002-09-02 Paul Eggert <eggert@twinsun.com>
12699 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12700 directory names are generally preferable to physical names.
12702 2002-09-02 Akim Demaille <akim@epita.fr>
12704 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12705 Reported by Raja R. Harinath.
12706 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12707 * bin/autoupdate.in: Use error instead of die.
12709 2002-09-01 Paul Eggert <eggert@twinsun.com>
12711 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12712 ordinary shell concatenation rather than echo+tr+sed command that
12713 runs afoul of a long-line-related sed bug in Solaris 8.
12715 * bin/autoheader.in (parse_args): --warning -> --warnings.
12717 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12718 stdout, as traditional "ls" does.
12719 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12720 _AC_COMPILER_EXEEXT_O): Likewise.
12721 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12723 * bin/autoconf.as: Add --prepend-include option. This patch was
12724 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12725 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12727 * bin/autoconf.in, configure: Regenerate.
12729 * doc/autoconf.texi (Special Shell Variables): Mention
12730 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12732 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12733 MAILPATH and set PS1, PS2, PS4 to default values, to work
12734 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12735 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12736 the Autoconf documentation specifies; fall back to "unset" only if
12737 this fails. Use a shell for-loop for this rather than an m4 loop,
12738 to shorten the output script.
12740 2002-08-30 Paul Eggert <eggert@twinsun.com>
12742 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12743 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12744 for the CDPATH problem. Document PWD.
12745 (Limitations of Builtins): Document the problem that "cd $foo" and
12746 "ls $foo" may refer to different directories in shells conforming
12747 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12748 example, since the old example is now out of date.
12750 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12751 FOO" and "ls FOO" talk about different directories; this catches
12752 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12755 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12756 of rolling our own unset.
12757 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12758 in practice we needn't worry about CDPATH if unset doesn't work.
12760 * Makefile.in, aclocal.m4, bin/Makefile.in,
12761 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12762 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12763 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12764 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12765 tests/Makefile.in: Regenerate with Automake 1.6.3.
12767 * config/config.guess, config/config.sub, config/mkinstalldirs:
12770 * configure: Regenerate with self.
12772 2002-08-30 Kevin Ryde <user42@zip.com.au>
12774 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12777 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12779 * bin/autom4te.in (Request::load): Correctly test for "do" read
12782 2002-08-29 Akim Demaille <akim@epita.fr>
12784 * lib/Autom4te/General.pm (&xqx): New.
12785 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12786 hand, which is not portable.
12788 * bin/autom4te.in: Use them.
12789 Use &error instead of die.
12790 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12793 2002-08-17 Paul Eggert <eggert@twinsun.com>
12795 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12796 default list of compilers to try, since it was long ago superseded
12797 by the ksh fc builtin. Suggested by Steven G. Johnson.
12799 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12801 * doc/autoconf.texi (Invoking autom4te): End the option table,
12802 fixing a bug introduced by the previous patch.
12803 (Limitations of Make): Add a 'target lookup' subentry in the
12804 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12806 2002-07-29 Mark D. Roth <roth@feep.net>
12808 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12809 options and use $AUTOM4TE_PATH.
12810 * doc/autoconf.texi: Remove documentation of autom4te
12811 --include-envvar and --site-macro-subdir options and document
12812 use of $AUTOM4TE_PATH.
12813 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12814 arguments from each language section.
12816 2002-07-29 Paul Eggert <eggert@twinsun.com>
12818 * doc/install.texi: Include copyright symbol in copyright notice.
12820 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12822 (AM_MAKEINFOFLAGS): New macro.
12823 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12824 * Makefile.am (INSTALL): Use the new macros.
12825 Use -o rather than --output, since "missing" does not grok --output.
12827 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12829 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12830 comments do not always work. Never trust the exit status of
12833 2002-07-24 Kevin Ryde <user42@zip.com.au>
12835 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12836 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12838 2002-07-23 Paul Eggert <eggert@twinsun.com>
12840 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12841 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12842 apparently treats PATH="nonexistent" as if it contained ".".
12843 Bug reported by Stefan `Sec' Zehl.
12845 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12847 * doc/autoconf.texi (Limitations of Make): Mention the special
12848 handling of the obj/ directory by BSD make.
12850 2002-07-20 Kevin Ryde <user42@zip.com.au>
12852 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
12855 2002-07-19 Akim Demaille <akim@epita.fr>
12857 * doc/autoconf.texi (Function Portability): `exit'.

12868 2002-07-18 Akim Demaille <akim@epita.fr>
12870 * config/config.guess, config/config.sub: Update.
12872 2002-07-18 Akim Demaille <akim@epita.fr>
12874 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

13113 This improves on an earlier suggestion by H. Peter Anvin.
13115 2002-05-16 Paul Eggert <eggert@twinsun.com>
13117 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13118 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13119 Both macros now accept an optional source-dir arg.
13120 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13122 * NEWS: Document this.
13123 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13125 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13126 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13127 not for GNU extensions; this undoes part of the 2000-11-03 change,
13128 reverting to 2.13-compatible behavior.

13136 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13137 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13138 and it causes a 'test' syntax error if it fails.
13139 Bug reported by Stephen Gildea.
13141 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13142 If prototypes are supported, use them to check this at compile-time,
13143 instead of trying to check it at run-time. If we must do a run-time
13144 check, assume that setvbuf is standard when cross-compiling, as
13145 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13146 Bug reported by Paul D. Smith.
13148 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13149 argument specifying location of getloadavg.c. This removes a
13150 FIXME. This idea was taken from Jim Meyering's implementation in
13152 * doc/autoconf.texi (Particular Functions): Document this.
13153 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13154 that's what the code does; this fixes a bug reported by
13157 2002-05-03 Akim Demaille <akim@epita.fr>
13159 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13160 autopoint instead of gettextize.
13161 ($uses_alocal): Rename as...
13162 ($uses_aclocal): this.
13163 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13164 Suggested by Bruno Haible.
13166 2002-05-03 Akim Demaille <akim@epita.fr>
13168 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13170 2002-04-29 Paul Eggert <eggert@twinsun.com>
13172 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13173 files to be 1 second older; just set them to be the same time.
13174 Also, sleep 1 second after the first aclocal, to work around
13175 problems with sub-second time stamps on the input files.
13177 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13179 * doc/autoconf.texi: Mention "set -e -x" lossage
13180 under node "Limitations of Builtins".

13186 From Christian Cornelssen.
13188 2002-04-29 Akim Demaille <akim@epita.fr>
13190 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13191 of lack of $LINENO support, then the test will compare the $LINENO
13192 in testsuite vs. the lineno in the test file. This is wrong, of
13194 Be sure to protect it.
13195 Reported by Patrick Welche.
13197 2002-04-25 Akim Demaille <akim@epita.fr>
13199 * doc/autoconf.texi (Obsolete Macros): Typo.
13200 Reported by Vladimir Volovich.
13202 2002-04-25 Akim Demaille <akim@epita.fr>
13204 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13205 than some of the input files, hence, on the second run of aclocal,
13206 if some of its input are younger, make them older.
13207 Suggested by Paul Eggert.
13209 2002-04-25 Akim Demaille <akim@epita.fr>
13211 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

13217 and ac_subst_vars be sh variables containing the list of
13218 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13220 (_AC_INIT_PREPARE): Use them to log them.
13221 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13222 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13223 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13224 _AC_SUBST_FILES and _AC_SUBST_VARS.
13225 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13227 2002-04-24 Akim Demaille <akim@epita.fr>
13229 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13230 autoheader, so that automake does not complain about a missing
13231 config.h.in that was to be created.
13233 2002-04-23 Akim Demaille <akim@epita.fr>

13354 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13355 on Autotest and M4sh.
13356 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13357 (wrapsh.in): New target.
13358 * bin/autoconf.as: New, precursor of autoconf.in.
13359 (autoconf.in): New target.
13361 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

13364 with indented comments in rules.

13380 Reported by Ezra Peisach.
13382 2002-04-04 Andreas Schwab <schwab@suse.de>
13384 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13385 contains no literal separators.
13387 2002-04-03 Akim Demaille <akim@epita.fr>
13389 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13390 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13391 Use dnl, not the KILL diversion.
13393 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13394 (AC_CONFIG_LINKS): here.
13396 Don't use the KILL diversion, as it kills spurious output, which
13397 results in failures being hidden.
13398 Use m4_defn where appropriate.
13399 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13400 after the second argument.
13402 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13403 syntax, as it is provided by M4sugar.
13404 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13406 2002-04-03 Andreas Schwab <schwab@suse.de>

13409 expanded if $# <= 2.

13420 (_AC_COMPILER_OBJEXT): Use them.
13421 Fixes Debian #138666.
13423 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13425 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13427 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13428 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13429 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13430 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13431 (AC_C_CONST): Same.
13432 (AC_C_INLINE): Same.

13445 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13446 to avoid versions of HP C which don't allow that.
13448 2002-03-27 Paul Eggert <eggert@twinsun.com>
13450 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13451 (AS_SHELL_SANITIZE): Invoke it.
13452 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

13456 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13458 2002-03-26 Akim Demaille <akim@epita.fr>
13460 * doc/autoconf.texi (Introduction): The GNATS base moved.
13462 2002-03-25 Paul Eggert <eggert@twinsun.com>
13464 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13465 as POSIX requires, as it doesn't work with Zsh.
13466 * doc/autoconf.texi (Assignments): Document the problem.
13468 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13470 * doc/autoconf.texi (Limitations of Make): Mention more issue
13471 about VPATH, overriding of macros in sub-makes, and handling of
13474 2002-03-21 Paul Eggert <eggert@twinsun.com>
13476 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13477 problem with here-document buffer boundaries.
13479 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13480 when reinvoking the shell, to work around problems with installers
13481 who put strange things like "cd" commands in their environments.
13483 2002-03-19 Akim Demaille <akim@epita.fr>

13501 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

13505 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13506 (Limitations of Usual Tools): Add mkdir section.
13508 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13509 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13510 back on AS_DIRNAME to compute prefixes otherwise; this is
13511 roughly what mkinstalldirs does. That way, we need not have
13512 our own filename disassembler. The old disassembler did not
13513 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13515 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13516 Create at_test_all by a series of assignments,
13517 not by a single assignment of a long string. The latter causes ksh
13518 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13519 presumably because of a buffer overrun.
13521 2002-03-14 Paul Eggert <eggert@twinsun.com>
13523 * lib/autotest/general.m4 (at_times_skip):
13524 Renamed from at_times. Now a boolean.
13525 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13526 says 'times: not found'.
13528 2002-03-14 Akim Demaille <akim@epita.fr>
13530 * bin/autoreconf.in (&study_gettextize): New.
13531 (&autoreconf): Handle newest gettextize.
13532 Rerun aclocal if needed.
13533 Suggested by Andreas Schwab.

13555 2002-03-11 Andreas Schwab <schwab@suse.de>

13558 does not do it if --with-lispdir is given.

13567 subdirectory should exist.
13569 2002-03-08 Akim Demaille <akim@epita.fr>
13571 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13573 2002-03-08 Akim Demaille <akim@epita.fr>
13575 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13576 aliases the actual variables, and modifications of the former
13579 2002-03-08 Akim Demaille <akim@epita.fr>
13581 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13582 because of C-c: have m4 output in tmp files, then mv them.
13584 2002-03-08 Akim Demaille <akim@epita.fr>

13605 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13606 * lib/autoconf/general.m4 (AC_INIT): More informative error
13607 message for LIBOBJ.
13609 2002-03-04 Akim Demaille <akim@epita.fr>
13611 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13614 2002-03-04 Akim Demaille <akim@epita.fr>
13616 * doc/autoconf.texi (Transforming Names): Equality between target
13617 and host is irrelevant.
13618 (Specifying Names, Canonicalizing): Remove all references to the
13619 backward compatibility hooks. Rather, collect them all into...
13620 (Hosts and Cross-Compilation): this new section.
13621 * doc/install.texi (System Type): Ditto.
13622 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13623 that `--host' implies cross-compilation.
13625 2002-03-04 Akim Demaille <akim@epita.fr>
13627 * doc/autoconf.texi (Evaluation Macros): New.
13628 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13630 (_m4_foreach): Define the variant with immediate evaluation so
13631 that it contains exactly the items, not an expression which
13632 evaluation is the current item.
13633 (m4_re_string, m4_re_word): Don't over quote them.
13635 2002-03-04 Akim Demaille <akim@epita.fr>
13637 Instead of having stacking `shift's evaluated at the end, let
13638 `foreach' loops immediately evaluate them.
13640 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13641 $*. This is the n-th time I change my mind, but hopefully this is
13644 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13646 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13647 it was only a hack for m4_text_wrap.
13648 (m4_car2): Remove, replaced by...
13650 (_m4_foreach): Adjust.
13651 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13652 m4_bpatsubst for clarification.

13703 Fix Autoconf PR/207:
13704 AC_PREFIX_PROGRAM fails with dashed program names
13706 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13707 variable when looking for the prefix program.

13743 2002-02-05 Akim Demaille <akim@epita.fr>
13745 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13767 * bin/autom4te.in (&parse_args): Implement `frozen files are
13768 optional are the sum of the previous files on the command line'.
13769 Also, pass `--reload-state=' on them, so...
13770 (handle_m4): don't.
13771 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13772 (M4sh): Rely on M4sugar.
13773 (Autotest, M4sh, M4sugar): Use frozen files.
13775 2002-01-31 Akim Demaille <akim@epita.fr>

13799 2002-01-29 Akim Demaille <akim@epita.fr>
13801 * tests/torture.at (Configuring subdirectories): Use configure.in,

13803 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13805 2002-01-28 Akim Demaille <akim@epita.fr>
13807 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13810 2002-01-28 Akim Demaille <akim@epita.fr>
13812 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13813 AUTOTEST_PATH *after* it was set.
13814 Don't put `.' in the PATH: the user should be precise and `./' if
13815 needed. In addition, given that the test suite does some `cd', if
13816 `.' is in the path, the `tested programs' sections will report
13817 programs found in the test suite's directory, while during the
13818 tests (performed in their own directory), these programs are no
13819 longer visible. In other words, the results is confusing and

13886 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13887 package.m4, since is really depends upon configure.ac, not
13889 * doc/autoconf.texi (testsuite Scripts): Adjust.
13890 * tests/Makefile.am (package.m4): New.
13891 EXTRA_DIST it since its a source.
13893 2002-01-06 Akim Demaille <akim@epita.fr>
13895 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13896 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13897 and PACKAGE_BUGREPORT from here...
13898 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13900 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13901 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13902 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13903 * tests/tools.at (autoheader): Adjust.
13904 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13906 2002-01-06 Akim Demaille <akim@epita.fr>

13912 * doc/autoconf.texi (Output): Improved wording regarding use of
13916 2001-12-18 Kevin Ryde <user42@zip.com.au>
13918 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13919 sometimes needing writable input.
13921 2001-12-17 Jim Meyering <meyering@lucent.com>
13923 * doc/autoconf.texi (New Macros): Tweak wording.
13925 2001-12-14 Akim Demaille <akim@epita.fr>
13927 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13928 trailing files, don't apply `-rf' to files which might not be
13929 created by configure (core, core.*, and *.core), but just `rm -f'.
13930 Suggested by Jonathan Kamens.
13932 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13934 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13936 2001-12-14 Akim Demaille <akim@epita.fr>
13938 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13940 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13942 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13943 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13944 abs_srcdir, top_srcpath to abs_top_srcdir.
13945 (_AC_OUTPUT_FILES): Adjust.
13946 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13947 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13948 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13950 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13952 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13953 C/Fortran linking on HP/UX, by extracting the Fortran library
13954 search path from the LPATH line in the $F77 -v output.
13956 2001-12-12 Kevin Ryde <user42@zip.com.au>
13958 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13959 forbidden file descriptors table.
13961 2001-11-26 Akim Demaille <akim@epita.fr>
13963 * bin/autoscan.in (%c_keywords): Build it at top level.
13964 Map to 1 in order to simplify its uses.
13966 2001-11-26 Akim Demaille <akim@epita.fr>
13968 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13969 Remove $filepath, useless.
13970 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13971 variables, they are really part of the tokens.
13972 Split the input line on spaces and then look for tokens.
13973 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13974 because of `lex$U.$(OBJEXT)'.
13975 (&scan_files): Use "@list" instead of join.
13976 * doc/Makefile.am (CLEANFILES): Add *.fns.
13978 2001-11-26 Akim Demaille <akim@epita.fr>
13980 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13981 Remove, replaced by...
13982 * tests/wrappl.in: Be common for all the Perl executables.
13983 In particular autoscan and autoheader want -I.
13984 * configure.ac: Adjust.
13985 * lib/autoscan/headers: errno.h is portable.
13987 2001-11-26 Akim Demaille <akim@epita.fr>
13989 * bin/autoscan.in (used): New.
13992 2001-11-26 Akim Demaille <akim@epita.fr>
13994 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13996 (&scan_sh_file): Remove a duplicate pattern.
13997 (&check_configure_ac): Use long options.
13998 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
14000 2001-11-26 Akim Demaille <akim@epita.fr>
14002 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
14003 Before, having a line containing the opening of a multi line
14004 comment made the whole line be ignored.
14006 2001-11-26 Akim Demaille <akim@epita.fr>
14008 * doc/autoconf.texi (Using an Autotest Test Suite): New.
14009 (testsuite Scripts): Be one of its subsection.
14010 (Autotest Logs): New.
14012 2001-11-26 Akim Demaille <akim@epita.fr>
14014 Test groups are now run two directories deeper.
14016 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
14017 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
14019 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
14020 top_srcdir, builddir and top_builddir.
14021 Use `at_*dir' relatively to the directory containing the
14022 suite, use `*dir' when relatively to the current group dir.
14024 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14026 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14027 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14028 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14031 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14033 * doc/autoconf.texi (Using System Type): Add an example of `case
14034 $host' usage so people quit using `case $target' everywhere.
14036 2001-11-22 Akim Demaille <akim@epita.fr>
14038 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14039 spotted by Jim Meyering.
14041 2001-11-16 Paul Eggert <eggert@twinsun.com>
14043 This patch implements a `long double' suggestion by Oliver Kiddle.
14045 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14046 static, to catch errors if the value isn't known at compile-time
14047 and the compiler supports dynamic arrays. Change its name from
14048 `_array_' to `test_array' to avoid potential name clashes.
14049 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14050 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14051 better than double. Catch a bug in GCC 2.95.2 x86.
14052 * doc/autoconf.texi (C Compiler): Document the above.
14055 2001-11-13 Akim Demaille <akim@epita.fr>
14057 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14059 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14061 2001-11-13 Akim Demaille <akim@epita.fr>
14063 * lib/autotest/general.m4 (AT_INIT): After having run the test
14064 group, go back to the initial directory, not to at_suite_dir.
14066 2001-11-13 Akim Demaille <akim@epita.fr>
14068 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14069 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14070 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14072 (AT_CHECK_CONFIGURE): Use absolute paths.
14073 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14074 The problem is still the old one: there is no means in M4 (that I
14075 know about) to create a defining macro, because there is no means
14076 to create `$1' etc., therefore, the defining macro ``swallows''
14077 all the arguments meant to the defined macro.
14079 2001-11-13 Akim Demaille <akim@epita.fr>
14081 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14082 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14084 * tests/aclocal.m4: Remove, as it is no longer used.
14086 2001-11-13 Akim Demaille <akim@epita.fr>
14088 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14089 variable names when referring to a single test group, or to
14090 `suite' when referring to the whole test suite.
14091 `at_last_test' is removed: m4 compute at_format itself.
14092 (at_stdout, at_stder1, at_stderr): New variables.
14093 (AT_CHECK): Use them.
14095 2001-11-13 Akim Demaille <akim@epita.fr>
14097 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14099 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14100 Do it as soon as a test fails, don't wait till the end of the test
14102 Don't remove $as_me.[0-9]*, since these files no longer exist.
14104 2001-11-13 Akim Demaille <akim@epita.fr>
14106 * tests/tools.at: Use absolute paths, since we are no longer run
14109 2001-11-13 Akim Demaille <akim@epita.fr>
14111 Now that tests are running in their own private dir, there is no
14112 need to list the files to remove at the end of tests groups.
14114 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14115 (AT_data_files, at_data_files): Remove.
14116 (AT_CLEANUP, AT_DATA): Simplify.
14118 Remove the group dir if !debug && !failed.
14119 * tests/atspecific.m4: Adjust.
14121 2001-11-13 Akim Demaille <akim@epita.fr>
14123 Start a new layout for Autotest: `testsuite' creates
14124 `testsuite.dir' in which the at-check-line etc. files are to be
14125 found, and `testsuite.dir/003' where the test group 3 is run.
14127 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14128 at_check_line_file, at_format, at_test_normalized, at_group_dir
14130 Create the directories.
14131 Use absolute paths for at- files.
14132 (AT_CHECK): Adjust.
14134 2001-11-11 Michael Matz <matz@kde.org>
14136 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14138 (m4_car): Properly quote arguments.
14140 2001-11-13 Akim Demaille <akim@epita.fr>
14142 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14143 with stricter rules on LIBOBJS.
14145 2001-11-12 Paul Eggert <eggert@twinsun.com>
14147 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14148 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14151 2001-11-12 Akim Demaille <akim@epita.fr>
14153 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14155 2001-11-12 Akim Demaille <akim@epita.fr>
14157 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14158 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14159 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14160 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14161 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14162 specify to what the macro should be defined (typically to 1).
14164 2001-11-12 Akim Demaille <akim@epita.fr>
14166 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14169 2001-11-12 Akim Demaille <akim@epita.fr>
14171 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14172 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14173 definition used by Automake where LEX is +/- "${missing} lex" and
14174 `missing' itself contains variables.
14176 2001-11-12 Akim Demaille <akim@epita.fr>
14178 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14179 Now that M4sh pushes BODY, the comments were output at the end of
14182 2001-11-08 Akim Demaille <akim@epita.fr>
14184 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14185 that we can trace macros from aclocal.m4.
14186 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14187 obsoleted, and redirect to the former anyway.
14188 Reported by Ralf Corsepius.
14190 2001-11-08 Akim Demaille <akim@epita.fr>
14192 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14193 processed only if present.
14194 * tests/torture.at (Configuring subdirectories): Use autoreconf
14195 instead of successive calls to autoconf.
14196 Add a nonexistent subdirectory to exercise the patch above.
14197 Reported by Ralf Corsepius.
14199 2001-11-08 Kevin Ryde <user42@zip.com.au>
14201 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14202 doesn't accept .S files.
14204 2001-11-07 Akim Demaille <akim@epita.fr>
14206 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14207 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14208 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14209 * bin/autom4te.in (warn_forbidden): New.
14210 (handle_output): Use it.
14211 Read m4_pattern_forbid with messages.
14213 2001-11-05 Akim Demaille <akim@epita.fr>
14215 * bin/autom4te.in (--normalize): Remove.
14216 * lib/autom4te.in: Adjust.
14218 2001-11-05 Akim Demaille <akim@epita.fr>
14220 * tests/Makefile.am (testsuite): Rename this target as...
14221 ($(TESTSUITE)): this.
14224 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14226 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14227 the --prefix option, also remove it's argument.
14229 2001-11-05 Akim Demaille <akim@epita.fr>
14231 * doc/autoconf.texi (testsuite Invocation): Update.
14232 (Writing testsuite.at): Update.
14234 2001-11-03 Akim Demaille <akim@epita.fr>
14236 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14238 2001-11-03 Akim Demaille <akim@epita.fr>
14240 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14241 (&file_name_is_absolute): New, wrappers around routines from
14243 Use and export them.
14244 (&find_configure_ac): Optionally take a directory where to look at.
14245 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14247 Default @ARGV to `.', not find_configure_ac.
14248 (&autoreconf): Argument is a directory.
14249 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14250 * doc/autoconf.texi (autoreconf Invocation): Update.
14252 2001-11-03 Akim Demaille <akim@epita.fr>
14254 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14255 (@export_forward_subs): New.
14256 Add basename, dirname, and fileparse.
14258 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14259 Don't look for aclocal flags if we already know aclocal is not
14261 Move aclocal.m4t only if it exists.
14262 Reported by Ezra Peisach.
14264 2001-11-03 Akim Demaille <akim@epita.fr>
14266 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14267 passed on command line, defaulting to ./configure.ac if present.
14268 (&maybe_autoreconf, File::Find): Remove, unused.
14269 (&autoreconf): If autoconf is not used, don't try to trace.
14271 2001-11-02 Akim Demaille <akim@epita.fr>
14273 * configure.ac: Bump to 2.52g.
14275 2001-11-02 Akim Demaille <akim@epita.fr>
14279 2001-11-02 Akim Demaille <akim@epita.fr>
14281 * config/config.guess, config/config.sub, doc/standards.texi:
14282 * config/lispdir.m4: Update from masters.
14283 * configure.ac: Bump to 2.52f.
14285 2001-11-02 Akim Demaille <akim@epita.fr>
14287 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14288 Don't run aclocal when aclocal.m4 is not from aclocal.
14290 Don't run libtoolize and gettextize if --install is not given.
14292 2001-11-01 Paul Eggert <eggert@twinsun.com>
14294 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14295 be invoked before _AS_LINENO_PREPARE.
14296 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14297 than character ranges.
14299 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14300 invoking AS_BASENAME. Set the locale variables to 'C' if
14301 possible, as POSIX requires this to get the traditional
14303 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14305 2001-10-31 Paul Eggert <eggert@twinsun.com>
14307 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14308 with {}, as that triggers a bug in Bash 2.05.
14310 (_AS_LINENO_PREPARE): Use Sed rather than
14311 Awk. Fix the sed prepass to work even if there are multiple
14312 instances of $LINENO on the same line. Do not substitute for
14313 other variables like $LINENOT. Do not check file dates; such a
14314 check is unreliable on sufficiently fast machines, and removing
14315 the check makes the code simpler and more reliable. Check for
14316 output and chmod failures.
14318 * doc/autoconf.texi (Special Shell Variables): Document
14321 2001-10-31 Akim Demaille <akim@epita.fr>
14323 * tests/Makefile.am (atconfig): Remove this target, Automake
14326 2001-10-31 Akim Demaille <akim@epita.fr>
14328 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14329 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14330 provided, while it is optional.
14331 * configure.ac: Adjust.
14333 2001-10-26 Paul Eggert <eggert@twinsun.com>
14335 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14336 lib/Autom4te/Struct.pm:
14337 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14340 * doc/autoconf.texi (Special Shell Variables): Document some
14341 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14343 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14344 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14345 eval $LINENO is not portable in practice.
14347 2001-10-24 Akim Demaille <akim@epita.fr>
14349 * lib/Autom4te/General.pm (backname): New.
14351 2001-10-24 Akim Demaille <akim@epita.fr>
14353 * m4/: Remove, merged into...
14356 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14358 * doc/autoconf.texi (Shellology): Mention the problems with bash
14359 2.05's use of ANSI quoting in its `set' builtin.

14363 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14364 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14365 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14366 POSIX decided to standardize on the int flavor of strerror_r.
14367 Always do char* test, as there's no reason not to.
14368 Assign to a char* var, to catch strerror_r that returns int*.
14370 * doc/autoconf.texi (Particular Functions):
14371 Document the above changes. Also, document the fact that
14372 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

14863 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14864 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14865 be used instead of ':'.
14866 * lib/autotest/general.m4: Replace occurrences of ':' in
14867 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14869 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14872 arguments. Fixed a typo.
14874 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14876 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14877 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14879 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14881 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14890 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14891 already have $file). Set output files to binary mode (helps avoid
14892 CR issues on DOSish systems).
14894 2001-09-19 Akim Demaille <akim@epita.fr>
14896 * lib/autotest/general.m4: Englishoes.
14897 From Tim Van Holder and Alexey Mahotkin.
14899 2001-09-18 Paul Eggert <eggert@twinsun.com>
14901 * doc/autoconf.texi (Common Shell Constructs): New node,
14902 documenting AS_DIRNAME.
14903 (Limitations of Usual Tools): Refer to it when discussing dirname.
14904 Also, update discussion of POSIX standard to reflect latest draft.
14906 * lib/autoconf/c.m4:
14907 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14909 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14910 Do not pass a first argument with leading '-'
14911 to expr, by parenthesizing initial integers that might be negative.
14913 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14914 now merely checks whether it is an error to pass an argument
14917 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14918 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14919 whether it is a (compile-time) error to pass an argument to
14920 getpgrp. This simpler test supports the revised documentation,
14921 and is all that AC_FUNC_GETPGRP's users really need.
14923 2001-09-18 Akim Demaille <akim@epita.fr>
14925 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14933 2001-09-18 Paul Wagland <paul@wagland.net>
14935 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14937 Add test for AS_BASENAME.
14938 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14939 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14940 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14941 * tests/base.at: Fixed the expected responses. The old ones were
14943 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14944 the documentation claims it should (and how it behaved in 2.13).
14946 2001-09-18 Akim Demaille <akim@epita.fr>
14948 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14949 the AC_CONFIG_COMMANDS invocation.
14950 This also solves the name clash problems.
14951 Don't set the package's ID.
14952 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14953 No longer to be shipped.
14954 (version.in): Remove.
14955 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14956 * lib/autoconf/status.m4: Adjust.
14957 Use `m4_PACKAGE_STRING'.
14958 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14959 the only optional argument is the name of the test suite.
14960 Expect `package.m4' to define the package signature.
14961 * lib/autom4te.in (Autotest): Add `package.m4?'.
14962 * tests/Makefile.am (package.m4): New.
14963 * tests/suite.at: ifnames is a victim.
14965 2001-09-18 Akim Demaille <akim@epita.fr>
14967 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14968 AC_LIBSOURCE, AC_CONFIG_FILES.
14969 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14970 program version string doesn't match the package's.
14971 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14974 2001-09-17 Paul Eggert <eggert@twinsun.com>
14976 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14977 Allow expression to return any value that can fit into unsigned long
14978 (not int, as before). Check for output errors.
14980 2001-09-17 Bruno Haible <haible@ilog.fr>
14982 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14983 Always include <stdio.h> and <stdlib.h>. Evaluate
14984 the expression in an extra function before these includes. Call
14985 fprintf "%d" only after ensuring the argument is of type 'int'.
14986 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14988 2001-09-17 Paul Eggert <eggert@twinsun.com>
14990 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14991 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14992 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14993 when they don't exist.
14995 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14996 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14999 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
15000 version with the version used by fileutils 4.1, except use
15001 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
15004 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
15006 2001-09-13 Akim Demaille <akim@epita.fr>

15046 * lib/autotest/general.m4 (AT_INIT): Create and remove
15047 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15048 test suites can cohabit.
15050 2001-09-13 Akim Demaille <akim@epita.fr>
15052 * tests/mktests.sh: Don't output banners for empty test files.

15161 the maintainer is dumb enough to do that...
15163 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15164 excellence in M4 quotation: consider `__file__' is active.
15166 And BTW, when invoking m4, pass the --include in the right order:

15252 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

15301 * bin/autoupdate.in, bin/autoheader.in: Adjust.
15302 Drop AC_MACRODIR dead for real.
15303 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15304 `autoheader: `config.hin' is created'.
15305 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15307 2001-08-31 Akim Demaille <akim@epita.fr>
15309 * bin/autoheader.in: Rewrite in Perl.
15310 * tests/autoheader: Adjust.

15314 * bin/autoconf.in (--include, -I): New option.
15315 Map --localdir, --autoconf-dir onto it.
15316 Forward autom4te's options instead of interpreting them.
15317 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15318 There is no such envvar since the inception of autom4te.cfg.
15319 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15320 * bin/autoupdate.in: Adjust, and perform more control.
15321 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15322 * tests/autoconf: Dittowise.
15324 2001-08-31 Akim Demaille <akim@epita.fr>
15326 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.

15329 Use -e, not -f, since /dev/null for instance is OK.
15330 (&parse_args): Adjust.
15331 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15333 2001-08-31 Akim Demaille <akim@epita.fr>

15340 * lib/Autom4te/General.pm (&find_peer): Remove.
15341 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

15343 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15344 find the executables for it.
15345 * tests/Makefile.am: Major cleanup. Too lazy to document...
15346 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15348 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15349 indeed related to running the test suite, while passing
15350 --autoconf-dir and others is related to running non installed
15351 Autoconf executables. So don't do that, leave it to...
15352 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15353 * tests/autoscan: New.
15354 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

15371 Suggested by Paul Eggert.
15373 2001-08-29 Akim Demaille <akim@epita.fr>

15840 autom4te.cache (it's a directory, not a file.
15841 * Makefile.am: Ditto (but maintainer-clean-local).
15843 2001-08-15 Akim Demaille <akim@epita.fr>
15845 * bin/autom4te.in (@m4_warning): New.
15846 (&handle_m4): Use it.
15847 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15848 warnings are issued at each run.
15849 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15850 is in the src tree.

15927 magic values from an object file when cross-compiling.
15928 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15930 2001-08-10 Akim Demaille <akim@epita.fr>
15932 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15934 Suggested by Russ Allbery.
15936 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15938 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15939 current $prefix to the sub-configures.
15941 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15943 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15944 extension (needed on BeOS). Reported by Guido van Rossum.
15946 2001-08-09 Akim Demaille <akim@epita.fr>
15948 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15950 2001-08-07 Akim Demaille <akim@epita.fr>
15952 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15954 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15955 No need to remove the files before and after the each test, before
15956 each test and at the end of the suite is enough.
15957 Display only the children `times', not the shell's.
15958 If the test failed or was skipped, at-times is not available.
15960 2001-08-07 Akim Demaille <akim@epita.fr>
15962 Always produce testsuite.log, including when there are no
15963 failures. This helps getting information on skipped tests, and
15964 duration of the tests. Err, implement the latter btw.
15966 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15967 Dump information on the first run of each test.
15968 (AT_CLEANUP): Create `at-times' containing the duration of the
15971 2001-08-07 Akim Demaille <akim@epita.fr>
15973 The use of `dumpstat' revealed that `len' was used although it
15974 should not. m4_text_wrap was using it, but in the Autoconf world
15975 where it is legal. Hence (i) test M4sh in its own world, not
15976 Autoconf's, and (ii), ahem, fix the bug :)
15978 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15979 does not like `' instead of [].
15980 (AT_INIT): Forbid `^_?AT_'.
15981 And don't output such tokens.
15982 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15983 `script.as', and `autom4te.cache'.
15984 Remove `empty' and `macro' which are no longer used.
15985 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15986 * tests/m4sugar.at: Use it.
15987 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15989 2001-08-07 Akim Demaille <akim@epita.fr>
15991 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15993 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15995 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15997 2001-08-04 Akim Demaille <akim@epita.fr>
15999 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
16000 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
16002 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
16003 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
16004 (AC_F77_MAIN): Likewise.
16006 2001-08-04 Akim Demaille <akim@epita.fr>
16008 Don't rely on M4sugar outputting the patterns in files, since we
16009 might process the output _without_ running m4, hence without these
16012 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
16013 * bin/autom4te.in (@Request::includes): Remove, unused.
16014 (@Request::source): Rename as...
16015 (@Request::input): this.
16016 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
16017 (&handle_output): Fetch the patterns from the traces.
16018 `$forbidden' and `$allowed' are constant: use m//o.
16019 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
16020 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
16022 2001-08-04 Akim Demaille <akim@epita.fr>
16024 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
16025 autoconf', i.e., in addition to caching traces, cache the output.
16027 * bin/autom4te.in (Request::cache): Rename as...
16028 (Request::id): this.
16029 ($cache, $icache, $tcache, $ocache): New.
16030 (&handle_m4): Save M4 output in the cache instead of $tmp.
16031 (&handle_output): Adjust.
16032 (&up_to_date_p): Check that the output cache is up to date too.
16033 (top level): Run `&handle_m4' iff force or the cache is invalid.
16034 Run `&handle_output' if the output cache is more recent.
16036 2001-08-04 Akim Demaille <akim@epita.fr>
16038 * bin/autom4te.in ($force): New.
16039 (&parse_args, &print_usage): -f, --force is a new option.
16040 (&handle_output): CPP directives might have spaces after `#'.
16041 (&parse_args): The first file only can be frozen.
16043 2001-08-04 Akim Demaille <akim@epita.fr>
16045 Don't let autom4te compute the `include' traces several times:
16046 first check that the trace cache file is up to date, and then
16047 compare its timestamp with that of the output.
16049 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16050 the preamble. Don't require 5.005 as Autom4te::General does it,
16051 and better yet (use `use', not `require'!).
16052 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16053 Class::Struct as Autom4te::Struct.
16054 * lib/Autom4te/General.pm (File::stat): Use it.
16055 (&mtime): New, export it.
16056 * bin/autom4te.in: Use it.
16057 Declare `$req' is invalid if it is outdated.
16058 Don't declare it valid before saving it if something went wrong.
16060 2001-08-04 Akim Demaille <akim@epita.fr>
16062 Autom4te shall not encode Autoconf data, and preselecting traces
16063 must be proposed to the users.
16065 * bin/autom4te.in (@required_trace): Remove.
16067 (&parse_args, &print_usage): -p, --preselect is a new option.
16068 (&up_to_date_p): Adjust.

16071 2001-08-04 Akim Demaille <akim@epita.fr>
16073 * tests/tools.at (autoconf --trace: user macros): Check traces on
16074 macros invoked without arguments, and macros invoked with multiple

16094 (@m4_builtin): this.
16095 (%m4_builtin_alternate_name): New.
16096 (&parse_args): Complete the trace requests with alternate names.

16102 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
16103 m4_if, and m4_wrap.

16107 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
16108 (m4_divert_pop): Dump the whole diversion stack when a diversion
16110 * bin/autom4te.in (&handle_output): Remember of the first
16111 occurrence of a possibly undefined macro, not the last.
16112 Complain about the possibly undefined macros in the same order as
16113 the appear in the output.
16114 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16115 * tests/tools.at (autoconf: forbidden tokens, basic)
16116 (autoconf: forbidden tokens, exceptions): No longer sort
16117 autoconf's stderr, as it is now deterministic.
16118 Check that `dnl' is caught.
16120 2001-08-01 Akim Demaille <akim@epita.fr>

16140 `END', as `Autom4te::General::END' will be triggered.
16141 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
16142 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
