1702 Cover more potentially problemtic file names. Use the new
1705 Properly handle funny file names for headers in config.status.
1706 The test suite did not cover this bug because the code was not
1707 quoting properly the arguments of `rm -f' (which "fails" silently)
1708 as well as the arguments of `diff' (whose output was redirected to
1709 /dev/null so we couldn't see its error message).

1827 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1829 <DEFAULTS>: Delay computation of variables based on $at_dir...
1830 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1831 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1832 <PARSE_ARGS>: Parse new option.
1833 <HELP_TUNING>: Document it.

1849 * doc/autoconf.texi (Particular Programs): Do not mention the
1850 Autoconf version in which the AC_PROG_INSTALL change was done.
1851 Suggested by Paul Eggert.

1855 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1856 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1857 mode, we change to the source directory, also set $ac_pwd so we

1859 * tests/torture.at (Deep Package): Extend test to contain two
1860 config subdirs on the top level.
1862 Fix parallel `maintainer-check'.
1863 * Makefile.am (maintainer-check-tests): Depend on `all'.

1891 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1893 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1894 check_SCRIPTS. Building the wrappers for `all' allows help2man

1914 (m4_require): Use m4_do, not m4_join.
1916 Fix some whitespace tests on cygwin.

1938 config.guess, and config.sub to test source tree.

1941 * tests/torture.at (Substitute a 2000-byte string): Drop
1942 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1943 (Substitute a newline, datarootdir workaround): Likewise.
1944 (Define a newline): Adjust for linenumber changes in configure.ac.
1945 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1954 * tests/m4sh.at (LINENO): Quote $0.
1956 Fix testsuite program wrapper for whitespace in `pwd`.
1957 The problem here is that the usual mantra is that command
1958 variables can contain arguments, thus we cannot just escape
1959 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1960 $top_builddir/tests directory early in $PATH, so that the
1961 wrappers are found by their plain name.
1962 * tests/wrapper.as: Put $testdir early in $PATH.

1975 <at_func_create_debugging_script, Driver Loop>:
1976 Quote $at_group_dir.
1977 * tests/autotest.at (whitespace in absolute testdir): New test.
1979 * lib/autom4te.in: Quote @datadir@.
1981 Proper file name escaping in Autoconf programs and Perl modules.
1982 This includes escaping of characters special to the shell
1983 as well as special to Perl, e.g., leading `<' or `>'.
1984 For example, when $file starts with `>', `open ">$file"'
1985 wrongly tries to append to a different file.
1986 * bin/autoconf.as: Fix quoting for autom4te options.
1987 * lib/Autom4te/General.pm (shell_quote): New function, taken
1988 from coreutils, written by Jim Meyering.

1998 test. Test twice, with special characters allowed on w32, and the
1999 rest. Test leading and trailing whitespace, for `open_quote'.
2000 (autotools and whitespace in file names): New, analogous test.

2008 (update_file, contents): Use it.
2010 * Makefile.am (autom4te-update): Rewrite for git.
2012 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2014 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
2016 Fix copyright years.
2017 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
2018 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

2026 When using older automake, don't downgrade build-aux/texinfo.tex.
2027 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
2028 * doc/Makefile.am (TEXINFO_TEX): Add.
2030 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2032 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2033 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2034 #undef as this runs afoul of our new way of creating config.h.
2035 Problem reported by Jim Meyering in
2036 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2038 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2040 Fix autom4te for unusual characters in input file names.
2041 * bin/autom4te.in (files_to_options): Quote active characters
2043 * tests/tools.at (autom4te and white space in file names):
2046 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2047 Document that Tru64 awk always splits $0.
2049 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2051 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2052 `#AT_STOP_...' line at the end of each test.
2054 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2056 * lib/autotest/general.m4 (AT_INIT): For awk line number
2057 extraction script, ensure `$at_group' has a defined value
2058 even for the empty set, and properly quote its usage inside
2061 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2063 * doc/autoconf.texi (Shell Functions): New chapter. Document
2064 IRIX sh $0 issue in functions, move content from ...
2065 (Portable Shell): ... here.
2066 (Shell Script Compiler): Note that shell functions are not
2067 totally unportable any more.
2069 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2070 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2072 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2073 extracting the line numbers of the last needed test.
2075 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2077 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2080 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2082 Fix IRIX testsuite debugging failures: $0 in functions.
2083 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2084 Do not use $0 inside a function, as IRIX sh will set that to the
2085 function name rather than the script invocation name.
2087 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2088 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2090 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2091 to extract test scripts.
2092 (AT_INIT): Extract and cache test script line numbers.
2094 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2096 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2097 subsequent fixups; the awk -> here-document conversion trashes
2098 performance too much with AIX sh.
2100 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2102 * tests/local.at: Do not test m4, perl with AT_TESTED.
2104 Diagnose and guard against write errors dealing with config.status.
2105 The general idea is this: all write failures from `configure'
2106 writing `config.status' are indicated by $ac_write_error, which
2107 is only checked at the end. This is safe because config.status
2108 code is not executed before the file is complete. Other write
2109 failures, be they inside config.status, or in sub shell/awk
2110 scripts spawned from configure or config.status, typically need
2111 earlier checking, as their results are used right afterwards.
2112 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2113 before writing config.status, check afterwards.
2114 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2115 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2116 Set `ac_write_error' for write failures to config.status. Barf
2117 upon write failures to temporary files.
2118 Adjust note about closing and reopening the here-document.
2119 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2120 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2121 reopening the here-document.
2122 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2123 Ensure `ac_write_error' does not escape into config.status.
2124 Also, add a couple of code paths not yet exercised in the test
2125 suite: a config file with input from stdin, and a config header
2127 Suggestion for catching write errors by Bruno Haible.
2129 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2131 Avoid error with Tru64 awk and testsuite lines with many words.
2132 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2133 reads the testsuite, set the field separator to an unusual value,
2134 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2135 even splits the input if $i, i>0, was never accessed in the script.
2137 Revert 2007-10-17 change.
2138 * TODO: Multiline args in config files and headers mean something
2139 different and are not fixed, see
2140 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2141 Report by Stepan Kasal.
2143 * doc/autoconf.texi (Generic Programs): Fix typo.
2145 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2147 AC_*_TOOL does not canonicalize the prefix
2148 * doc/autoconf.texi (Generic Programs): Do not say that
2149 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2151 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2153 Diagnose write errors in config.status instantiations.
2154 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2155 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2157 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2158 Extend test to also check for some write error failures, using...
2159 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2160 Report by Bruno Haible.
2163 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2165 (_AT_CHECK): Use less indentation, to save space.
2167 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2169 Add witness macro for @top_build_prefix@ substitution.
2170 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2171 (_AC_OUTPUT_FILE): Mention it here.
2173 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2174 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2176 * lib/autotest/general.m4 (at_func_test): Remove.
2177 (AT_INIT): Pre-extract test groups into separate files.
2178 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2179 Remove at-test-source files together with the $at_group_dir.
2180 * tests/autotest.at (Long test source lines): New test.
2182 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2184 Shell functions and variables may share a namespace.
2185 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2188 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2190 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2193 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2195 * lib/autoconf/status.m4: Fix a couple of comment typos.
2197 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2199 2007-11-13 Jim Meyering <meyering@redhat.com>
2201 Clean up the rule to create "expr".
2202 * tests/Makefile.am (expr): Don't redirect directly to target.
2203 Redirect just once, not for each echo statement.
2204 Use $@, not literal "expr".
2206 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2208 Don't worry about preprocessor when testing long long.
2209 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2210 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2211 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2212 These no longer check for preprocessor flaws.
2213 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2214 Do not check for preprocessor flaws.
2216 2007-11-13 Jim Meyering <meyering@redhat.com>
2218 Adapt dependencies, now that a version change doesn't modify configure.ac
2219 * GNUmakefile: Remove "make clean" kludge.
2220 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2222 Don't redirect directly to target.
2223 Use $@, not literal "version.m4".
2225 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2227 * doc/autoconf.texi (Making testsuite Scripts): Document
2228 ":;{" shorthand as in previous patch.
2230 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2232 * doc/autoconf.texi (Limitations of Builtins): Document problem
2233 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2235 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2236 Use ":;{" shorthand.
2237 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2239 2007-11-12 Jim Meyering <meyering@redhat.com>
2241 Add more non-srcdir build support.
2242 * GNUmakefile (dummy): Split a long line.
2243 Add -v option to autoreconf invocation.
2245 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2246 * GNUmakefile (dummy): Remove INSTALL.
2248 Remove racy commands to build scripts in bin/ and tests/.
2249 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2250 are guaranteed to be built, remove the rules that tried to build
2251 them. Before, with a parallel build, these rules could lead to
2252 two processes writing tests/wrapper.in concurrently.
2254 Build in man/ only *after* building in bin/ and tests/.
2255 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2256 in both bin/ and tests/.
2258 Accommodate non-srcdir build-from-checkout.
2259 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2260 Use git's --git-dir=$srcdir/.git option.
2261 Add quotes, in case tarball_version_file contains shell meta-characters.
2262 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2263 * configure.ac: Pass "." to git-version-gen.
2265 Avoid spurious test failures due to version skew.
2266 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2268 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2270 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2271 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2272 Remove conftest.dSYM directory.
2273 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2274 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2275 Remove `conftest.*' recursively.
2276 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2277 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2279 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2281 Report and analysis by Jeff Squyres and Peter O'Gorman.
2283 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2285 Fix typos in variable names.
2286 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2288 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2290 Document that $((expression)) is not portable.
2291 * doc/autoconf.texi (Shell Substitutions): Here.
2293 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2295 Ignore configure --help* errors due to LINENO-impaired shells.
2296 * tests/torture.at (Configuring subdirectories, Deep Package):
2297 In the --help* tests in read-only trees, make `.' temporarily
2298 writable again for the `stderr' file, and ignore errors due to
2299 the attempt to write configure.lineno.
2300 Report by Patrick Welche.
2302 2007-11-10 Jim Meyering <meyering@redhat.com>
2304 Generate package.m4 in build-dir, not srcdir.
2305 * tests/Makefile.am (package.m4): Adjust target.
2306 Don't redirect directly to $@.
2307 (CLEANFILES): Add package.m4.
2308 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2310 When running $(AUTOTEST), search "." before searching $(srcdir).
2312 Avoid a race condition that would make parallel "distclean" fail.
2313 * tests/Makefile.am (distclean-generic): Replace the default,
2314 automake-provided rule with an identical one, but with an additional
2315 dependency on distclean-local. Simply adding the dependency would
2316 cause automake not to emit the rule at all.
2317 * BUGS: Building with -jN works, now.
2319 Distribute git-version-gen.
2320 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2321 since GNUmakefile is distributed, and requires it for dist* rules.
2323 Remove two more generated files from version control.
2324 * INSTALL: Remove generated file.
2325 * lib/autoscan/autoscan.list: Remove generated file.
2327 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2329 * GNUmakefile (PATH): Remove stray apostrophes; they become
2330 part of PATH, which isn't wanted here.
2332 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2334 New config files output variable `top_build_prefix'.
2335 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2337 * doc/autoconf.texi (Preset Output Variables): Document it.
2339 Report by Bob Friesenhahn.
2341 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2342 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2343 function, to parametrize arithmetic with expr vs. the shell.
2344 Use it where possible.
2345 Suggestion by Benoit Sigoure.
2347 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2349 Adjust the documentation of autotest WRT atlocal.
2350 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2351 when using Automake, to write a rule to produce atlocal, since it's
2352 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2353 distributed, not atconfig.in.
2355 2007-11-04 Eric Blake <ebb9@byu.net>
2357 Update list information.
2358 * README: Mention new autoconf-commit list.
2359 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2361 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2363 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2365 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2367 * build-aux/.gitignore: Ignore mkinstalldirs.
2369 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2371 2007-11-03 Jim Meyering <meyering@redhat.com>
2373 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2374 * build-aux/git-version-gen: This syncs from coreutils.
2376 Adjust the build procedure so "make check" works reliably.
2377 * README-hacking: Include an extra step between "make" and
2378 "make check" to ensure that the latter passes.
2380 Use just-built tools, when possible.
2381 * GNUmakefile (PATH): Set and export here, ...
2382 (dummy): ... rather than here.
2384 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2385 and Andreas Schwab <schwab@suse.de>
2387 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2390 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2392 * configure.ac (AC_PREREQ): Require version 2.60, for
2393 AC_PROG_SED, AC_PROG_GREP.
2395 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2396 and Jim Meyering <meyering@redhat.com>
2397 and Andreas Schwab <schwab@suse.de>
2398 and Eric Blake <ebb9@byu.net>
2400 Document a bug in GNU Bash with compound commands and redirections.
2401 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2402 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2405 2007-11-03 Eric Blake <ebb9@byu.net>
2407 Support m4 1.4.5 in testsuite.
2408 * tests/torture.at (Define a newline): Exclude line numbers in
2410 Reported by Ralf Wildenhues.
2412 2007-11-03 Jim Meyering <meyering@redhat.com>
2414 Remove automake-provided files from version control.
2415 * build-aux/elisp-comp: Remove file.
2416 * build-aux/install-sh: Remove file.
2417 * build-aux/missing: Remove file.
2418 * build-aux/mdate-sh: Remove file.
2419 * build-aux/.gitignore: New file.
2420 Suggestion from Ralf Wildenhues.
2422 2007-11-03 Eric Blake <ebb9@byu.net>
2424 Adjust version comparison to account for git snapshot numbers.
2425 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2426 component separator.
2427 * doc/autoconf.texi (Number processing Macros)
2428 <m4_version_compare>: Document this change.
2429 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2431 2007-10-30 Bruno Haible <bruno@clisp.org>
2433 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2434 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2435 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2436 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2437 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2438 Suggested by Paul Eggert.
2440 2007-10-28 Jim Meyering <meyering@redhat.com>
2442 * README-hacking: Autoconf, Automake, and Perl are required to build.
2443 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2445 2007-10-28 Jim Meyering <meyering@redhat.com>
2447 README-hacking: Recommend running autoreconf -vi.
2448 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2449 so that we use just-built tools when they're available.
2450 Suggestions from Ralf Wildenhues.
2452 2007-10-28 Jim Meyering <meyering@redhat.com>
2454 Make inter-release --version output more useful.
2456 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2457 which indicates that it is built using the 19th change set
2458 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2459 is a prefix of the commit SHA1.
2460 * build-aux/git-version-gen: New file.
2461 * configure.ac: Run it to set the version.
2462 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2463 * Makefile.am (dist-hook): Arrange so that .version appears only
2464 in distribution tarballs, never in a checked-out repository.
2465 * .gitignore: Add .version here, too. Just in case.
2466 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2467 not configure.ac, now that the version number changes automatically.
2469 Ensure that $(VERSION) is up to date for dist-related targets.
2470 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2471 git-version-gen doesn't match $(VERSION), but only for dist targets.
2473 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2475 Fix `Deep Package' failure with a configure script early in PATH
2476 * tests/torture.at (Deep Package): Add `.' early in PATH.
2477 Report by Jim Meyering.
2479 2007-10-27 Jim Meyering <meyering@redhat.com>
2481 Remove all generated files from version control.
2482 * aclocal.m4: Remove.
2483 * configure: Remove.
2484 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
2485 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
2486 * README-hacking: New file: how to build from just-checked-out sources.
2488 2007-10-23 Eric Blake <ebb9@byu.net>
2490 Improve corner case of m4_expand.
2491 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
2493 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
2494 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
2497 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
2499 * doc/make-stds.texi: Update from gnulib.
2501 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2502 and Eric Blake <ebb9@byu.net>
2504 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
2505 problem reported by Bruno Haible in
2506 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2508 2007-10-22 Eric Blake <ebb9@byu.net>
2510 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2513 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2515 Don't check for bug in HP-UX 11.00 cpp.
2516 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):

3747 for C++; this drops support for anonymous struct and union types,
3748 which were problematic anyway.

3768 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3769 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3770 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3771 works but the latter doesn't, then it's a valid type.
3772 This lets people use function types and so forth.
3773 For C++ there doesn't seem to be a simple solution, so leave it alone.
3774 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3775 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

3997 will generate an infinite loop for the example derived from
3998 Autoconf's mktime test.
3999 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
4000 Also, clarify unsigned multiplication overflow.
4002 2007-01-04 Eric Blake <ebb9@byu.net>
4004 * bin/Makefile.am (RELEASE_YEAR): New macro.
4005 (edit): Use it to supply correct copyright year to scripts.
4006 * bin/autoconf.as (version): Use it.
4007 * bin/autoheader.in ($version): Likewise.
4008 * bin/autom4te.in ($version): Likewise.
4009 * bin/autoreconf.in ($version): Likewise.
4010 * bin/autoscan.in ($version): Likewise.
4011 * bin/autoupdate.in ($version): Likewise.
4012 * bin/ifnames.in ($version): Likewise.
4014 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4016 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4017 feedback. The most important changes document what happens when
4018 you convert an out-of-range value to a signed integer type, and
4019 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4022 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4023 rewrite, taking notions from the recent discussion on the gcc and
4024 autoconf mailing lists; please see
4025 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4026 and follow the many links.
4027 (Integer Overflow Basics, Signed Overflow Examples):
4028 (Optimization and Wraparound, Signed Overflow Advice):
4029 (Signed Integer Division): New sections.
4031 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4033 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4034 preprocessor macro arguments in traced name.
4035 * doc/autoconf.texi (Defining symbols): Document longstanding
4036 support for AC_DEFINE-ing macros with arguments, and document
4037 behavior when the same variable has multiple AC_DEFINEs.
4038 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4039 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4040 macros directly, giving much shorter and simpler code.
4042 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4044 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4045 space before "$ac_configure_args" to prevent a 'config.status
4046 --recheck' failure if ac_configure_args doesn't contain a leading
4047 space. This works around a problem with the XEmacs configure.ac,
4048 which uses the (undocumented) ac_configure_args variable
4049 inconsistently with Autoconf.
4051 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4053 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4054 Include <limits.h>, and use its INT_MAX to rewrite the
4055 j loop so that it does not overflow 'int'. Problem reported by
4057 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4058 Play it safe by shifting left by 1 rather than multiplying by 2,
4059 as GCC is less likely to optimize this away when the value
4060 is signed (when it assumes overflow leads to undefined behavior).
4061 Also, don't assume time_t uses two's complement.
4063 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4065 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4066 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4067 dumps core on it. Report by Tim Rice.
4069 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4071 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4072 --disable-option-checking to --help output even when
4073 AC_PRESERVE_HELP_ORDER is not used.
4074 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4075 --with argument, rather than argument with [-.] replaced by
4077 * NEWS: Fix typo in previous change; the news was in the
4080 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4082 * NEWS: Warnings are now generated by default for unknown
4083 --enable-* and --with-* options.
4084 * doc/autoconf.texi (Option Checking): Renamed from
4085 (Configure Option Checking). Tighten up the wording a bit.
4086 (External Software, Package Options): Cross-reference to Option
4087 Checking, and use this to shorten our section.
4088 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4089 "$x" to test "x$foo" != x.
4090 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4091 Don't warn if $enable_option_checking is "no".
4092 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4093 ac_unrecognized_opts to the empty string.
4094 Don't echo the unrecognized opts, as this might mishandle
4095 backslashes or leading -.
4096 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4097 usage next to the other --disable-FEATURE options in the
4100 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4102 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4103 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4104 Print warning for unrecognized --with and --enable options
4105 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4106 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4107 Disable option checking when subdirs are configured.
4108 (AC_OUTPUT): If warnings are enabled, print warning about
4109 unrecognized --with and --enable options at the end of
4110 the configure output (as well as at the beginning).
4111 * doc/autoconf.texi (Option Checking): New node.
4112 Document new option warning functionality.
4114 2006-12-16 Eric Blake <ebb9@byu.net>
4116 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4117 * NEWS: Start news for current version.
4119 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4121 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4122 Define HAVE_GETMNTENT to 1, not to the empty string.
4123 Problem originally reported by Jochen Friedrich in
4124 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4126 This change prompted by a problem report by Andrey Simonenko in
4127 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4128 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4129 object-like macros only, in the traditional portable character
4131 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4132 Warn about attempts to define things that are not identifiers.
4133 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4134 awful hack that AC_DEFINEd macro names containing parentheses.
4136 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4138 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4139 too drastic, even if Texinfo in theory requires it for info mode.
4141 (config.status Invocation): Renamed back from Recreating a
4143 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4144 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4146 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4148 * NEWS: Version 2.61a.
4150 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4151 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4153 * NEWS: Document changes with echo and printf, and the lack
4154 of limits on the total size of multi-line values of substituted
4155 variables, and the AC_FUNC_FSEEKO fix.
4157 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4159 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4160 Writing configure.ac.
4161 (Autoconf Input Layout): Renamed from configure.ac Layout.
4162 (Recreating a Configuration): Renamed from config.status Invocation.
4163 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4164 (acconfig Header): Renamed from acconfig.h.
4165 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4166 (Writing Testsuites): Renamed from Writing testsuite.at.
4167 (Autom4te Cache): Renamed from autom4te.cache.
4169 * BUGS: Remove mention of VPATH problem, since it's now documented
4170 not to be a bug in the Autoconf build procedure itself, but rather
4171 a problem with the proprietary `make' programs.
4173 * doc/autoconf.texi (Build Directories): Add a cross reference
4176 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4177 * doc/standards.texi: Sync from gnulib.
4179 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4180 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4181 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4182 generated automatically.
4184 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4186 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4187 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4188 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4190 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4192 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4193 `CEOF$ac_eof' special marker, the awk script cannot contain a
4194 line matching `^CEOF', so this is not needed any more.
4195 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4196 special marker in the test.
4198 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4200 * tests/tools.at (autom4te preselections): Use `find -newer';
4201 remove one of the sleeps.
4203 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4204 more readable, using ...
4205 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4207 * doc/autoconf.texi (autoheader Invocation): Do not double-
4208 quote the parameter of `AH_BOTTOM' in the example.
4210 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4212 * doc/autoconf.texi (Configuration Headers): Remove the
4213 example with multiple input files.
4214 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4215 multiple input files.
4217 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4219 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4220 creating the awk substitution script, handle one input line at a
4221 time, so that the maximum length of a substituted (multi-line)
4222 value is not limited by the size of the sed pattern space.
4223 The trade-off is a slightly repetitive sed script.
4224 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4225 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4226 * tests/torture.at (Substitute a 2000-byte string): Increase the
4227 test with several long lines, they should not be caught by sed
4230 * tests/tools.at (autom4te preselections): New test, to flag
4231 entries missing from autom4te.cfg.
4232 Report by David Byron <dbyron@hheld.com>.
4234 * tests/torture.at (Substitute a 2000-byte string): Actually use
4235 AC_PROG_AWK, so the last change works as intended.
4236 (Substitute and define special characters): Likewise.
4237 (Substitute a newline): Likewise.
4239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4240 instead of `awk' consistently.
4241 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4242 * tests/torture.at (Torturing config.status): Test both the
4243 result of AC_PROG_AWK and plain awk.
4244 (Substitute a 2000-byte string): Likewise.
4245 (Substitute and define special characters): Likewise.
4246 (Substitute a newline): Likewise.
4248 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4250 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4251 can be assigned to a function pointer. Problem reported by
4252 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4253 part of a patch by Ralf Wildenhues in that same bug report.
4255 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4257 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4258 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4260 2006-12-01 Eric Blake <ebb9@byu.net>
4262 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4263 cross-compiling from cygwin to mingw.
4264 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4265 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4266 to lib/autoconf/c.m4.
4268 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4270 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4271 string for more reliable failure. Wrap the entire test that
4272 causes the broken Solaris printf to dump core, in a subshell,
4273 so the segmentation fault message is reliably suppressed.
4274 Fix shell expansion errors by using /usr/ucb/echo always;
4275 avoid an error on systems without it by another subshell.
4276 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4277 subshell-$as_echo to `as_echo', for better error message.
4279 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4281 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4282 `BASH_SOURCE' contain a newline, set them to empty, as they may
4285 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4287 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4288 years and is too hard to maintain now. The last straw was
4289 reported by Jerker Baeck in
4290 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4291 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4292 * doc/autoconf.texi (Particular Functions): Move
4293 AC_FUNC_SETVBUF_REVERSED from here...
4294 (Obsolete Macros): ... to here. Say that it does nothing now.
4295 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4296 Turn into (almost) a no-op.
4298 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4300 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4301 These macros are obsolescent and new applications shouldn't need them.
4302 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4303 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4304 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4305 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4306 (AC_FUNC_VPRINTF): Likewise.
4307 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4308 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4309 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4311 * doc/autoconf.texi (Setting Output Variables): Mention that
4312 @VAR1@VAR2 has unspecified behavior. Problem reported by
4314 * NEWS: Mention this.
4316 * Makefile.am: Put only a single '#' into the copyright notice,
4317 so that it's also present in the output file. Standardize wording
4318 in makefile copyright notices to match GNU coding standards.
4319 * bin/Makefile.am: Likewise.

4332 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4334 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4335 in the sed script that mangles the awk script: delete up to the
4336 first exclamation mark only.
4337 * tests/torture.at (Substitute and define special characters):
4340 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4342 Rewrite config files generation: avoid quadratic growth in
4343 the number of substituted variables by using awk instead of sed
4344 for the bulk of the substitutions.
4345 * NEWS: Mention this.
4346 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4347 forbidden in the output (and thus input) file.
4348 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4349 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4350 generate just one large awk script for substitutions,
4351 eliminating much of the earlier complexity, while adding some
4352 new complexity. Only expand the substitution templates at
4353 configure time, for smaller configure script size. If
4354 _AC_SUBST_FILES are used, test 'awk' for working getline support
4355 at config.status time. If absent, interpolate through the
4356 shell. The awk script was written with much help
4357 from Paolo Bonzini and Paul Eggert.
4358 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4359 (_AC_SED_FRAG_NUM): Likewise.
4360 (_AC_SUBST_CMDS): Renamed from...
4361 (_AC_SED_CMDS): ...this.
4362 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4363 * tests/torture.at (Substitute a 2000-byte string): Also
4364 substitute a line with 1000 words, and a variable with several
4366 (Substitute and define special characters): Test awk special
4367 characters, and put substitution input strings `@foo@' in the
4368 output, to test that no recursion happens; test several other
4369 combinations from Paolo Bonzini.
4371 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4373 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4374 that replaced echo with AS_ECHO where this wasn't necessary.
4375 Problem reportd by Ralf Wildenhues.
4376 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4377 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4378 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4380 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4382 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4384 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4386 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4387 that traditional Awk lacks 3-arg "split". It has it.
4388 Mention that FS must be a single character, and a few other
4389 99-byte limits of traditional Awk.
4390 Mention that if (i in a) doesn't work with traditional Awk.
4392 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4394 * tests/autotest.at (BSx641-newline in command):
4395 (BS-BS-newline in command, BSx640-newline in command):
4396 (Newline-CODE-BS-newline in command):
4397 (Single-quote-BS-newline in command):
4398 (Single-quote-newline-BS-newline in command):
4399 Use printf '%s\n' instead of echo, for portability to hosts
4400 where echo interprets backslashes. This will break on hosts
4401 that lack printf, but for now let's assume all such hosts
4402 are dead (if not, we should get reports of test failures).
4404 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4406 'echo' has some portability problems, when given a first argument
4407 with a leading '-', or when given any argument containing '\'.
4408 Avoid using 'echo' in these cases.
4409 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

4412 * lib/autotest/general.m4 (AT_INIT): Likewise.
4413 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4414 argument might be unportable.

4435 scheme wouldn't work with AS_ECHO.
4436 * lib/autotest/general.m4 (AT_INIT): Likewise.
4437 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4438 Don't use ECHO_T, since ECHO_N is now reliable.
4439 * lib/autotest/general.m4 (AT_INIT): Likewise.
4440 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4441 rather than using a here-document to put the script into a file.

4445 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4446 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4447 bug, but we might as well stop using ECHO_N and ECHO_C internally.

4449 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4450 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

4452 operand, as AS_ECHO requires. Avoid double file name expansion.
4453 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4454 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4455 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4456 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4457 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4458 Double-quote strings that would otherwise contain M4 comments.
4459 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4461 * configure.ac (AC_INIT): Bump to 2.61a.
4464 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4468 * configure.ac (AC_INIT): Bump to 2.61.
4471 * tests/autotest.at (Macro with backslash in a test title):
4472 Comment out for now, as this tests neither fails nor passes
4473 reliably. Problem reported by Ralf Wildenhues.
4475 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4477 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

4551 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4552 benefit of platforms like Solaris+GCC where it is common to have a
4553 non-working g++ installation.
4555 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4556 and Joel E. Denny <jdenny@ces.clemson.edu>
4557 and Paul Eggert <eggert@cs.ucla.edu>
4559 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4560 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4563 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4565 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4566 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4567 Imported from a similar patch to gnulib by Bruno Haible.
4569 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4571 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4588 and Stepan Kasal <kasal@ucw.cz>
4590 Handle special characters in test case titles correctly.

4593 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4594 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4595 argument. Extend to check titles printed by ./micro-suite and

4597 (Backquote in a test title,
4598 Single-quote in a test title,
4599 Double-quote in a test title): Don't expect failure anymore.
4600 (Backslash in a test title): Put a non-whitespace character after the
4601 backslash so that Bourne shells might actually see it as an escape
4603 (Brackets in a test title,
4604 Pound in a test title,
4605 Comma in a test title,
4606 Quoted Macro in a test title,
4607 Macro in a test title,

4609 (Macro with backquote in a test title,
4610 Macro with double-quote in a test title,
4611 Macro with backslash in a test title): New tests expected to fail.
4612 * tests/torture.at (#define header templates): M4-quote this title in
4613 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4614 The visible effect was a stray [] in the testsuite output.
4616 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4618 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4619 `trap ... 0' inside a function, for AIX sh.
4621 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4623 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4624 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4625 5363) simply issues a warning when dividing by zero at compile
4626 time. Problem reported by Elias Pipping.
4628 2006-10-26 Eric Blake <ebb9@byu.net>
4631 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4632 show effect on macros that expand with commas.
4633 Reported by Joel E. Denny.

4657 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4659 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4660 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4661 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4662 reported by Nelson H. F. Beebe for Coreutils 6.4.
4664 * tests/tools.at (autoconf --trace: user macros): Remove test
4665 for tracing multiline macros, since m4 1.4.7a uses a different
4666 way to number lines. Problem reported by Ralf Wildenhues.
4668 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4670 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4671 /dev/null since the heuristics for interactive behaviour was

4675 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

4692 * NEWS: Remove AC_CACHE_CHECK_INT.
4693 * doc/autoconf.texi (Caching Results): Likewise.
4694 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4695 AC_CACHE_CHECK_INT, since it's no longer public.
4696 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4697 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4725 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4727 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4728 looking for special shell characters.
4729 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4730 macro defined by AS_VAR_PUSHDEF before passing it as a

4742 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4744 (Imported from Automake.)
4745 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4746 which incorrectly sets the mode of an existing destination
4747 directory. In some cases the unpatched install-sh could do the
4748 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4749 system. We hope this is rare in practice, but it's clearly worth
4750 fixing. Problem reported by Alex Unleashed in
4751 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4752 Also, don't bother to check for -m bugs unless we're using -m;
4753 suggested by Stepan Kasal.
4755 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4757 Import this change from Automake:
4759 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4760 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4761 is enabled by default with gnu and gnits strictness.
4762 Report from Bruno Haible.
4764 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4766 gnu and gnits modes.
4768 Import this change from Config:

4773 Import this change from Gnulib:
4775 2006-09-16 Karl Berry <karl@gnu.org>
4776 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4777 to avoid sectioning errors.
4779 Import these changes from Texinfo:
4781 2006-10-04 Karl Berry <karl@gnu.org>
4782 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4783 (\quoteexpand): rename to \rquoteexpand.
4784 (\codequoteleft): new def, to look for @set codequotebacktick.
4785 (\lquoteexpand, \quoteexpand): new defs.
4786 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4787 (\code): must use new \...Char values, since now ` is active.
4789 2006-08-26 Karl Berry <karl@gnu.org>
4790 * build-aux/texinfo.tex (\textdegree): New command.
4792 2006-08-12 Karl Berry <karl@gnu.org>

4797 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4799 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4801 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4802 added to the template can get mangled.
4804 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4806 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4807 include the default headers, and redefine obstack_chunk_alloc
4808 and obstack_chunk_free. Fixes false failure with glibc.
4810 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4812 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4813 for backward compatibility with Libtool 1.5.22. Problem reported
4816 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4818 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require

4825 the NonStop platform.
4826 * doc/autoconf.texi (Posix Variants): Likewise.
4827 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4829 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4830 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4831 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4832 Use a better substitute, by inspecting the output of "ls"
4833 rather than just using ":".
4834 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4835 rather than AS_EXECUTABLE_P, since we needn't worry about
4836 non-regular files here.
4838 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4839 due to configuration hassles with this. See Tonya Underwood's report
4840 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4841 * doc/autoconf.texi (Special Shell Variables): Likewise.

4844 Stepan Kasal <kasal@ucw.cz>
4846 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4847 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4849 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4851 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4852 initialization which is not inherited through the environment
4853 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4854 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4856 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

4859 problems with mkdir -p -m.
4861 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4863 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4864 comment about ac_cpp_err; it was incorrect, and anyway
4865 ac_cpp_err is being removed below.
4866 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4867 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4868 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4870 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4871 with werror_flag and conftest.err and so forth. This is more
4872 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4873 and anyway the user shouldn't normally want to see this gorp logged.
4874 Problem reported by Ralf Wildenhues.
4875 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4876 empty, not 'no', since the rest of the code uses 'test -z'.
4878 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4880 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4881 Use a single call to AC_DO_TOKENS rather than multiple, for
4883 (_AC_LINK_IFELSE): Test that resulting file is executable.
4884 Problem reported by mwoehlke in
4885 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4887 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4888 than creating a file to use with test -x; this is much faster.
4890 2006-10-02 Bruno Haible <bruno@clisp.org>
4892 * lib/autom4te.in (Automake-preselections): Add
4893 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4895 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4897 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4898 standard error, `experr' should be used, not `expout'.
4900 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4902 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4903 fseeko testing program twice; just use the earlier result.
4904 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4905 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4906 still doesn't let the program compile.
4907 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4910 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4911 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4912 include it, without including anything else.
4913 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant

5371 "volatile" means. Derived from thoughts by Ben Pfaff in
5372 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5374 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5376 * doc/autoconf.texi: Fix some typos.
5378 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5380 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5381 more globally, since the 2006-06-30 patch didn't suffice. Problem
5382 reported by Keith Marshall. Also, don't bother with builddir2,
5383 since it shouldn't be needed any more.
5385 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5387 * doc/autoconf.texi (Generic compiler characteristics):
5388 Document AC_COMPUTE_INT. Fix wrong statements on Default
5389 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5391 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
5392 (_AC_COMPUTE_INT): Add obsoletion warnings.
5393 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
5396 * NEWS: Document change.
5398 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5400 * doc/autoconf.texi (Volatile Objects): New section.
5402 * NEWS: Document previous change.
5404 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5406 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5407 Require that long long int be at least 64 bits wide. C99 requires
5408 this and enough programs depend on it so we should check for it.
5409 Bruno Haible reports in
5410 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5411 that long long int is 32 bits wide with some nonstandard compilers.
5412 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5414 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5416 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5417 to a nonexistent file, so that we don't have to worry about
5418 a local site configuration that doesn't use /usr/local.
5419 Problem reported by Keith Marshall in
5420 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5422 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5424 * doc/autoconf.texi: Be more consistent about using @acronym with
5425 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5426 quite right (it talked about "OSF/Tru64", even though the
5427 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5428 and it even mentioned "OSF 4"!) and at this point there's little
5429 reason to talk about OSF any more, since it died in 1994.
5430 (Specific Compiler Characteristics): Simplify example of
5431 negative-size array.
5432 (File Descriptors): Reorder to make the text flow better.
5433 Remove joke about "appreciate the various levels"; I didn't get it.
5434 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5435 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5436 (File Descriptors, Limitations of Usual Tools):
5437 Tone down the advice against renaming or removing open files.
5438 (Limitations of Usual Tools): Add a new section, on 'rm'.
5440 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5442 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5443 -lXt in LIBS, idea from Karsten Hopp; this was due since
5446 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5447 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5448 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5449 (which belong to Xt, not X itself). See Debian bug 327655.
5451 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5453 * configure.ac (AC_INIT): Bump to 2.60a.
5456 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5460 * configure.ac, NEWS: Update.
5462 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5464 * config/texinfo.tex: Sync from upstream.
5466 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5467 quadrigraph correctly in traces.
5469 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5472 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5473 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5475 * doc/autoconf.texi (Changed Directory Variables): New node,
5476 to document the whole `datarootdir' business a bit better.
5478 * tests/torture.at (datarootdir workaround): Extend test.
5479 Prompted by report by Alexandre Julliard.
5481 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5483 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5484 when using default mode of IBM C 6 for AIX. Problem and two-line
5485 fix reported by Larry Jones.
5487 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5489 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5490 about literal '${datarootdir}' if a definition is found in the
5493 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5495 * NEWS: Use "M4" rather than "m4" when appropriate.
5496 Problem reported by Eric Blake.
5497 * doc/autoconf.texi: Likewise.
5498 Use @acronym around BSD, GCC, and GNU when appropriate.
5499 (Why GNU M4): Renamed from "Why GNU m4".
5500 (Redefined M4 Macros): Mention that Posix
5501 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5502 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5505 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5507 * bin/autom4te.in (handle_output): Do not forbid the empty
5509 * tests/tools.at (autoconf: the empty token): New test.
5511 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5513 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5514 calls, so that we do not care whether they are LIFO or FIFO;
5515 in the m4_wrap, do not check which diversion is the topmost
5516 one, just check that the stack is balanced at the end.
5517 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5518 base diversion forever--pop the previous diversion before
5519 opening the new one; consequently, remove the m4_wrap call.
5520 * lib/autotest/general.m4 (AT_INIT): Likewise.
5521 * tests/m4sugar.at: Do not use
5522 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5524 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5525 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5527 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5528 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5529 Rework example of m4wrap token-pasting trouble so that it doesn't
5530 care whether it's LIFO or FIFO.
5531 Fix some "contrary to"s that are awkward in English.
5533 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5535 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5536 to `yes' instead of `int$1_t' if the type is found, for more
5537 consistent configure output (where $1 is the number of bits).
5538 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5539 Suggested by Bruno Haible.
5541 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5542 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5543 with system headers. Report by Bruno Haible.
5545 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5547 * config/config.guess, config/config.sub: Sync from upstream.
5549 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5550 in order to avoid picking up an older installed frozen m4sh.m4f.
5551 Besides an outdated shell startup, this could have been created
5552 by an earlier M4 version with incompatible frozen file format.
5554 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5556 * README: Recommend m4 1.4.4 instead of 1.4.3..
5557 * doc/autoconf.texi: Likewise.
5558 (Special Chars in Names): Say that $(.FOO) is portable, as
5559 suggested by Stepan Kasal.
5560 (Installation Directory Variables, Build Directories):
5561 (Automatic Remaking, Subdirectories, Fortran Compiler):
5562 (Making testsuite Scripts, Defining Directories):
5563 Quote variable usages better.
5564 (Making testsuite Scripts): Add clean-local rule to makefile
5565 snippet, by Eric Blake.
5566 (Installation Directory Variables): Fix table item font.
5567 Reword slightly to clarify. Generalize advice about
5568 not using special characters to include all file-related
5569 vars, not just VPATH.
5570 (Special Chars in Variables): Warn about special characters in
5572 (Assignments): Clarify default-value example as suggested by
5574 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5575 (Special Shell Variables): Note leading ./ or ../, as suggested
5577 (Limitations of Builtins): Under cd, warn about CDPATH.
5578 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5581 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5583 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5584 `@var', for texi2html.
5585 (Systemology): Some more word wrapping, for DVI output.
5586 (autom4te Invocation): The short option for `--melt' is `-M',
5589 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5591 * doc/autoconf.texi: More formatting and English tweaks,
5592 many suggested by Ralf Wildenhues.
5593 Reword to avoid "@code{...}'s" and the like, since it's ugly
5594 with Emacs info mode. discontents -> woes.
5595 Put a few "will"s back. time stamp -> timestamp.
5596 side-effect -> side effect.
5598 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5600 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5601 Warn about $@ not persisting. Problem reported by Julien Danjou in
5602 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5603 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5604 Mention other special chars, too.
5606 2006-06-14 Eric Blake <ebb9@byu.net>
5608 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5610 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5612 * doc/autoconf.texi: Some systematic minor improvements, as
5613 follows. Use "makefile" when talking about makefiles
5614 generally (which might be named "makefile" or "Makefile" or even
5615 "foo.mk"), "Makefile" when talking about a specific makefile
5616 called "Makefile". This unclutters the text from weird quotes
5617 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5618 values" rather than "@var{foo}s" and similar constructs containing
5619 "}s". Use "Make rules" rather than "Makefile rules". Minor
5620 English-language improvements. Change the prefix "sub-" to "sub"
5622 Put blank lines around examples more consistently.
5623 Avoid "rather" and "very" as intensifiers.
5624 Avoid "will" as an auxiliary.
5625 (Limitations of Make): Split this node into....
5626 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5627 (Leading _ in Macro Names, Backslash-Newline-Newline):
5628 (Backslash-Newline Comments, Long Lines in Makefiles):
5629 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5630 (obj/ and Make, make -k Status, VPATH and Make):
5631 (VPATH and Double-colon, $< in Explicit Rules):
5632 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5633 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5634 New nodes, resulting from splitup of Limitations of Make.
5635 All cross-references changed. Raise the top node from
5636 a section to a chapter, and all subnodes accordingly.
5637 Redo the introductory wording to match the new organization.
5638 (Installation Directory Variables): Use an example that is
5639 closer to what Autoconf actually does. Mention that VPATH's
5640 value should not contain metacharacters or white space.
5641 (Fortran Compiler): Fix a VPATH bug in an example.
5642 (Leading _ in Macro Names): Mention that this problem is no longer
5643 of practical concern.
5644 (VPATH and Make): Reword the advice to make it clearer
5645 that Autoconf and Automake support VPATH in non-GNU make, but
5646 many packages have bugs in this area.
5647 ($< in Explicit Rules): Refer to Build Directories rather
5648 than using a (non-VPATH-safe) example.
5649 (Automatic Rule Rewriting): Mention the sort of disaster that
5650 can ensue with Solaris-style rule rewriting with VPATH.
5652 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5654 * doc/install.texi (Compilers and Options): Weaken the
5655 suggestion to use GNU make for VPATH builds.
5657 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5658 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5660 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5661 in regular expression.
5663 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5665 * doc/autoconf.texi (Installation Directory Variables):
5666 Drop extra @samp from `@table @samp' item.
5667 (Limitations of Usual Tools): Comment fix.
5668 Do not nest @samp just to point to other table items.
5669 (Writing testsuite.at) <AT_CHECK>: The second argument to
5670 `@dvar' is already @samp'ed.
5671 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5672 do not use @var in the second argument.
5674 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5676 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5677 $as_shell.exe too. Problem reported by Andreas Buening in
5678 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5680 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5682 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5683 `unused variable' compiler warning, for `-Wall -Werror'.
5684 Reported by Jaap Haitsma in
5685 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5687 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5689 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5690 case the compiler dumps core. Problem reported for
5691 OpenServer 5.0.7 by Tim Rice in
5692 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5693 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5696 2006-06-06 Tim Rice <tim@multitalents.net>.
5698 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5699 "ERROR" only shows up in "make check" output if there is an
5702 2006-06-06 Eric Blake <ebb9@byu.net>
5704 * tests/tools.at (automatically allowed tokens): Fix typo.
5706 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5708 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5710 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5711 typically overflows on x86 CPUs, even though the C standard
5714 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5716 * configure.ac (AC_INIT): Bump to 2.59e.

5723 * config/texinfo.tex: Sync from upstream.
5725 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5726 seen, invoke libtoolize with `--ltdl' argument.
5727 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5729 Suggested by Eric Blake.
5731 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5733 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5734 reported by Ralf Wildenhues.

5750 * tests/base.at: Check AC_REQUIRE's error message.
5751 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5753 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5755 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5756 `expout' as the last parameter.
5757 * tests/tools.at: Adapt to the above change.
5759 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5761 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5762 information about race-free implementations of mkdir.

5771 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5773 * NEWS: GNU make now recommended for VPATH builds.
5774 Mention that some macros are now documented to be obsolescent.
5775 * doc/autoconf.texi:
5776 Prefer "current" to "modern" to describe
5777 currently-used (albeit perhaps old-fashioned) hosts.
5778 Mention which ancient features no longer need to be worried about.
5779 setgid -> set-group-ID
5780 setuid -> set-user-ID (these are the Posix terms)
5781 Fix some misuses of "only".

5796 Omit longwinded and obsolescent discussion of cp -f.
5797 Modernize discussion of expr, ls.
5798 (Limitations of Make): Modernize discussion of VPATH builds.
5799 Mention $? as a workaround in some cases.
5800 * doc/install.texi (Basic Installation):
5801 Mention "./configure; make; make install" first. Be more
5802 specific about why this file is generic. Remove unnecessary
5803 parens. Remove misleading "only". Remove obsolete advice
5804 about csh. Don't say "configure" takes awhile; say it
5805 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5806 and CC=c99 rather than CC=c89, as these are blessed by current
5807 Posix. Recommend GNU make if doing a VPATH build.
5809 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5811 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5812 examples involving shell prompts.

5851 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5853 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5854 about quoting ac_try: quote all of it, if any of it seems suspicious.
5855 This means we don't have to worry about ${ or sed any more.
5856 Also, double-quote the case statement, to work around misuses via
5857 underquoting as reported by Ralf Wildenhues in
5858 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5859 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5860 undocumented and dangerous macro.
5861 Problem reported by Ralf Wildenhues in
5862 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5864 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5866 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5867 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5868 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5870 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5872 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5873 since evidently some packages rely on the old, broken behavior.
5874 Problem reported by Ralf Wildenhues in
5875 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5876 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5877 pre-2006-05-26 definitions, but leave in the comments that
5878 these macros are dangerous and should not be used.
5879 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5880 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5881 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5882 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5883 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5885 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5887 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5888 the use of 'tr', since this is our only use of 'tr'.
5890 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5891 and Paul Eggert <eggert@cs.ucla.edu>
5893 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5894 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5896 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5898 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5899 the output file in the `${datarootdir}' test.
5901 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5902 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5904 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5905 mention of `datarootdir' in the input file(s), but literal
5906 `${datarootdir}' in the output file, and we haven't warned yet,
5907 then warn as well: the user may have (erroneously) used
5908 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5909 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5910 * tests/torture.at (datarootdir workaround): Extend this test.
5913 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5914 and Paul Eggert <eggert@cs.ucla.edu>
5916 * doc/autoconf.texi (autoheader Invocation): The first argument to
5917 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5918 alternatives and clear up the language a bit.
5920 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5922 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5923 ac_config_guess, ac_config_sub, ac_configure.
5924 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5925 Fix typo that prevented an unnecessary space from being removed.
5926 Problems reported by Ralf Wildenhues in:
5927 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5929 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5931 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5932 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5933 Don't use the term "thread-safe" to talk about mkdir race
5934 conditions, since the problem is more a process than a thread
5935 issue. Problem reported by Stepan Kasal in:
5936 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5937 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5938 the test for 'install' more closely. Look at MKDIR_P first.
5939 Look in the PATH, and at /opt/sfw/bin.
5940 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5941 Don't bother to try mkdir -p, since we already check mkdir --version;
5942 just look at the version number. (There's no easy way to check
5943 for race-free implementations.)
5944 * tests/tools.at (autoconf: subdirectories): Adjust to above
5945 changes, since MKDIR_P now might end in "/mkdir -p".
5947 * doc/autoconf.texi (autoheader Invocation): Mention that the
5948 first arg of AC_DEFINE_UNQUOTED must be a literal.
5949 Problem reported by Ben Pfaff in
5950 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5952 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5953 * doc/autoconf.texi (Special Chars in Variables): New section.
5954 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5955 (Installation Directory Variables): Quote $(datadir) better.
5956 (Limitations of Builtins): Describe some of eval's trickiness.
5958 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5959 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5960 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5961 in front of every arg, not just trailing args. Quote apostrophes.
5962 (_AC_EVAL_ECHO): New macro.
5963 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5964 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5966 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5967 exposed by quoting of eval argument. Put the command on line line
5969 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5970 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5971 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5972 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5973 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5974 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5975 Use eval more safely.
5976 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5977 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5979 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5980 lines, exposed by quoting of eval argument.
5982 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5983 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5985 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5986 initialization of `ac_cv_exeext', do not override it if it was
5987 already set, unless it was set to `no', for compatibility with
5988 Autoconf-2.13, and comment this.
5989 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5990 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5991 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5992 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5993 Document that this test may be overridden by setting
5996 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5998 Revert these two patches:
6000 2006-04-06 Eric Blake <ebb9@byu.net>
6001 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6002 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6005 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6006 Clean up _AC_COMPILER_EXEEXT* macros.
6007 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6008 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6009 ac_file to the name of the default output file and call
6010 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6011 initial `rm' of the candidate files...
6012 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6013 the same list in subsequent `rm' calls, and for the temporary
6014 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6015 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6016 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6017 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6018 no longer needed) by libtool. Make it a cache check.
6019 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6020 copied here by mistake.
6021 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6022 _AC_COMPILER_EXEEXT.
6023 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6024 _AC_COMPILER_OBJEXT directly.
6025 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6027 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6029 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6030 Fix description of how the buggy `sed' works.
6032 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6036 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6037 ENOLCK. Only mention `make -j' when applicable. Only raise
6038 fatal errors when `make -j' is involved. Improve error message.
6040 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6042 * doc/autoconf.texi (Here-Documents): We now know more about
6043 the variable expansion in here documents bug.
6044 Thanks to Tim Rice and Stepan Kasal.
6046 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6047 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6049 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6051 * tests/autotest.at (Multiline command from M4 expansion):
6052 No failure to be expected if the shell quotes newlines in
6053 commands in the `set -x' output. Report by Tim Rice.
6056 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6058 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6059 expansion in the here-documents used by config.status, as that
6060 runs afoul of the Korn shell version M-12/28/93d bug described in
6061 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6062 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6063 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6065 2006-05-23 Jim Meyering <jim@meyering.net>
6067 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6068 Fix typo introduced with 2006-04-02 change. It reversed the sense
6071 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6073 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6074 ac_dB slightly, to save bytes in the script.
6075 Max out at 50 lines, rather than 96; this is more likely
6076 (though not guaranteed) to avoid obscure 'sed' failures.
6078 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6080 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6081 `tr -d -' as bad option argument. Work around this by deleting
6082 an unrelated character.
6083 Report by Tim Rice <tim@multitalents.net>.
6085 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6086 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6087 Stepan Kasal <kasal@ucw.cz>
6089 * doc/autoconf.texi (Particular Programs): Do not promise that
6090 we always prefer the GNU version of the program, and that we
6091 search according to PATH; both rules can have exceptions.
6092 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6093 AC_PROG_SED. Move descriptions of limitations
6094 to the Limitations of Usual Tools section.
6095 (Limitations of Usual Tools) <sed>: Mention script length
6096 limitations with Solaris /usr/ucb/sed.
6097 <grep>: Fix wording for empty alternative. Mention that -c and
6098 -l should not be combined, and that -E and -F should not be
6101 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6102 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6104 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6105 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6107 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6109 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6110 AC_DEFINE is now passed to m4_pattern_allow.
6111 * NEWS: Mention that; likewise for AC_SUBST.
6112 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6113 the parameter to m4_pattern_allow.
6114 * tests/tools.at: Add a check for that.
6116 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6118 * lib/autoconf/status.m4: Fix typos.
6120 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6122 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6123 only the files that this macro generates.
6125 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6127 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6128 the HP-UX sed limitation of 99 commands, labels do not count.
6129 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6131 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6133 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6135 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6136 Import the following fix from coreutils:
6138 2006-01-13 Jim Meyering <jim@meyering.net>
6140 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6141 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6142 not double-quote uses of that variable, to accommodate the rare
6143 case in which getmntent is available in none of the libraries
6144 checked. This happens at least on FreeBSD 5.0.
6146 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6148 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6149 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6150 some other programs unwisely rely on these undocumented vars.
6151 But put in warning comments about them.
6152 Problem reported by Ralf Wildenhues in
6153 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6154 * NEWS: Document that these variables are intended to go away.
6156 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6158 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6159 and set the language to C++ (analogous to the equivalent Fortran
6162 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6163 * doc/autoconf.texi (C++ Compiler): Document it.
6164 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6167 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6169 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6170 that caused config.status to generate 100-command sed scripts; the
6171 portable limit is 99.
6173 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6175 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6176 variable `ac_d' instead of `d' to avoid infringing namespace.
6177 Report by Ralf Menzel.
6179 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6181 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6182 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6183 * tests/tools.at (autoconf: subdirectories): New test, taken from
6184 the corresponding problem report by Ralf Wildenhues in:
6185 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6187 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6188 Quote some uses of shell variables if they might suffer unexpected
6189 globbing. This doesn't fix all instances of quoting problems that
6190 I found, just the easy ones that look safe.
6191 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6192 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6193 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6194 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6195 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6196 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

6200 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6202 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6204 * bin/autoreconf.in ($help): Reword according to the manual.
6205 Suggested by Olly Betts.
6207 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6208 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6210 * bin/autoreconf.in: Pass the directory argument to
6211 `require_configure_ac'. Fix comment.
6212 * tests/torture.at (Configuring subdirectories): Expose this.
6213 Reported by Olly Betts.
6215 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6217 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6218 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6219 Automake as follows:
6221 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6222 `$configure_in' instead of `configure.in', to preserve
6223 directory component.
6225 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6227 * config/config.guess, config/config.sub, config/texinfo.tex,
6228 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6230 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6232 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6233 test for C99 conformance; (bool) 0.5 is an integer constant
6234 expression, but (bool) -0.5 is not. Problem reported by Fedor
6235 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6237 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6239 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6240 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6241 Warn about obsolete install-sh files. Remove stray sentence
6242 fragment and fix cross reference.
6243 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6244 install -d; this undoes the 2006-05-10 change.
6245 (MKDIR_P): Mark with AN_MAKEVAR.
6246 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6247 that we don't require $INSTALL to be thread-safe. Move comments
6248 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6249 of AC_PROG_INSTALL. Output a message saying that we're checking
6250 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6251 MKDIR_P instead of AC_SUBST.
6252 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6253 Special magic for MKDIR_P, too.
6254 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6256 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6258 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6260 Sync from Automake, as follows:
6262 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6263 * config/install-sh: Initialize IFS, so field splitting isn't
6265 * config/mkinstalldirs: Likewise.
6266 * config/missing: Remove superfluous quotes. Replace all uses of
6267 `[' by `test', for consistency, and for..
6268 * config/missing (sed_minuso, sed_output): New variables.
6269 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6270 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6271 Fixes `missing' to detect `--output' for help2man. Fixes
6272 PR automake/483. Report by Dennis J. Linse.
6273 (autom4te): Document in `missing --help'.

6277 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6278 * config/install-sh: Don't use 'path' to talk about file names,
6279 as per GNU coding standards. Close a race condition reported by Ralf
6280 Wildenhues and Stepan Kasal. There is still a race condition
6281 on hosts that predate Posix 1003.1-1992, but we can't help this.
6282 Don't mishandle weird characters like space on pre-Posix hosts.
6283 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6284 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6285 AC_PROG_MKDIR_P from AS_MKDIR_P.
6286 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6287 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6288 earlier editions are not (including Automake 1.8.3).
6289 Do not suggest mkinstalldirs for thread-safety.
6290 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6291 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6292 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6293 presence of special characters and race conditions.
6294 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6295 in Autoconf's name space.
6297 2006-05-10 Bruno Haible <bruno@clisp.org>
6298 and Paul Eggert <eggert@cs.ucla.edu>
6300 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6301 from Automake with minor changes.
6302 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6304 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6306 * config/install-sh: Update to Automake CVS version, as follows:
6307 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6308 * lib/install-sh: Simplify the expr implementation of dirname.
6309 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6310 * lib/install-sh: Handle --, and diagnose unknown options.
6312 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6314 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6315 `./autom4te' to create `./testsuite', since the `all' target
6316 will ensure its presence, but `installcheck' should not create
6317 the uninstalled wrappers.
6319 * tests/torture.at (Unusual Automake input files): Skip if we
6320 detect automake < 1.8.
6322 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6324 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6325 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6326 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6329 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6331 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6332 munge (multiple) white space and other oddities.
6333 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6334 single quotes in variable assignment.
6335 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6336 and similar failures by adding multiple spaces, tabs, and other
6338 Report and different test suggested by Francesco Romani
6339 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6341 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6342 single quotes, we only need to search for single quotes; this
6343 both simplifies the search pattern, and makes us less
6344 susceptible to `echo' variations for arguments not containing
6346 (_AC_ARG_VAR_VALIDATE): Likewise.
6348 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6350 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6351 `$*' and IFS concatenation issue with traditional shells and
6352 bash-2.04. Report by Seanster@Seanster.com.
6354 2006-05-03 Bruno Haible <bruno@clisp.org>
6356 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6357 precisely which Mac OS X versions have the od problem.
6359 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6361 * doc/autoconf.texi: Use @option systematically.
6363 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6364 and Bruno Haible <bruno@clisp.org>
6366 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6368 (Integer Overflow): Mention the special case of integer division
6371 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6373 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6374 traditional shells like the Solaris one that do not use the
6375 first IFS character for assembling `$*'.
6376 Prompted by a related report from autoconf_bug@nro.ca.
6378 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6379 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6381 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6382 Mention more problems with the -e option.
6384 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6387 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6389 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6390 in URLs to improve DVI formatted output (requires texinfo 4.6).
6391 (System Services, Systemology, Shellology): Likewise.
6392 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6395 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6397 (Runtime): Fix macro argument names to match description:
6398 `action-if-found' -> `action-if-true' and similarly.
6399 (Obsolete Macros): Likewise.
6400 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6401 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6402 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6404 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6406 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6409 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6412 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6414 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6415 /bin/sh set unsorted output.
6416 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

6421 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
6422 (Integer Overflow, Null Pointers, Buffer Overruns):
6423 (Floating Point Portability, Exiting Portably): New sections.
6424 (Writing Test Programs): Fix some langauge. Recommend exiting
6425 with status 1, not merely nonzero. Clarify exit declaration.
6426 (Run Time): Move C exit status stuff to new Exiting Portably section.
6427 (Systemology): Mention Posix and levenez. Update v7 reference.
6428 (Portable Shell): Mention the Posix shell.
6430 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6432 * bin/autoconf.as (me): Replace by as_me.
6434 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6436 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6437 since as_me isn't set yet.
6439 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6441 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6442 a few minor bugs in this area.
6444 * doc/autoconf.texi (Programming in M4sh): Comment out the
6445 documentation of AS_BASENAME, for now.
6446 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6447 (Limitations of Builtins) <basename>: Do not refer to
6449 * bin/autoconf.as (me): Don't use AS_BASENAME.
6450 (dir): Remove the unused variable.
6451 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6452 AS_DETECT_REQUIRED. All uses changed.
6453 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6455 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6456 (AS_BASENAME): Use "basename --" to protect against leading "-".
6457 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
6458 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6459 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6460 (_AS_DIRNAME_PREPARE): Likewise.
6461 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6462 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6463 (AS_DIRNAME): Use "dirname --".
6465 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6467 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6468 of "run time" and "run-time" changed to "runtime", for consistency.
6469 * lib/autoconf/fortran.m4: Likewise (in comment).
6470 * lib/autoconf/functions.m4: Likewise.
6471 * lib/autoconf/general.m4: Likewise.
6472 * lib/autoconf/headers.m4: Likewise.
6474 * doc/autoconf.texi (Run Time): Document the exit status situation
6475 with more accuracy and detail.
6477 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6479 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6480 Archive is not officially `GNU' any more. Update URL.
6481 (Defining Directories): Likewise
6482 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6484 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6486 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6487 newline from the `trap' code to finish `config.log'; the NetBSD
6488 /bin/sh resets the exit status after an empty command, as
6489 documented in doc/autoconf.texi.
6490 Reported by Dalibor Topic <robilad@kaffe.org>.
6492 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6494 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6495 Suggested by Bruno Haible.
6497 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6499 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6500 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6501 Instead, just list the shells that we know work.
6502 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6503 changed. Be more cautious about the _cv_ variable.
6504 * tests/tools.at (Syntax of the shell scripts): Check the
6505 _cv_ variable once, at first, to avoid an internal autoconf error
6506 when sh -n does not work.
6508 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6510 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6512 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6514 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6515 use ">&-" since we're only 99.999% sure that this is portable,
6516 and since the MinGW bug is fixed in a different way.
6517 * lib/autotest/general.m4 (AT_INIT): Likewise.
6519 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6521 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6522 before opening config.log, to avoid hitting a bug on MinGW.
6524 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6526 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6527 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6528 This works around a MinGW bug reported by Eric Paire.
6529 Make sure that all writes to the log file append to it,
6530 rather than possibly losing data.
6531 * lib/autotest/general.m4 (AT_INIT): Likewise.
6533 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6535 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6538 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6542 * configure.ac (AC_INIT): Bump to 2.59d.
6544 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6548 * Makefile.maint (news-date-check): Do not require a leading `*'
6549 before the release date in NEWS.
6551 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6552 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6554 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6555 the instantiated file do not contain the string 'datarootdir'
6556 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6557 @mandir@, replace the reference '${datarootdir}' by the value.
6558 * tests/torture.at (datarootdir workaround): New test.
6559 * NEWS: Advertise this temporary fixup.
6560 Based on a patch by Bruno Haible, reported and analyzed by
6561 Paul Eggert and Noah Misch.
6563 2006-04-12 Eric Blake <ebb9@byu.net>
6565 * tests/autotest.at (Debugging a failed test): Fix comment.
6567 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6569 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6570 all the changes since 2006-04-07.
6572 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6574 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6575 succeeded, but `ln -s file dir' failed, take care to remove the
6576 leftover target before the next test, to prevent its spurious
6577 failure; also make sure `ln file dir' works before selecting it.
6578 Thanks to Keith Marshall for pointing this out.
6581 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6582 assignments in `at_debug_args', so that we put them correctly
6583 in the `run' script.
6584 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6585 Reported by Eric Blake.
6587 2006-04-11 Eric Blake <ebb9@byu.net>
6589 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6590 top-level tests after micro-suite has been run. Used in...
6591 (Debugging a successful test, Debugging script and environment),
6592 (Debugging a failed test): ...these new tests. The first of these
6594 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6595 macro, split out from...
6596 (AT_INIT): ...here, so that using -d also generates a run script.
6597 Document that -d inhibits top-level logging.
6598 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6599 inhibits top-level logging; debug scripts are created.
6601 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6603 * tests/autotest.at (Empty test, Empty check): New test to check it.
6605 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6608 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6610 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6611 the files if a problem appears. Make the empty *.at files
6612 read-only, too. Proposed by Ralf Wildenhues.
6614 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6616 * config/Makefile.am: Add comment to force updated Makefile.in.
6618 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6619 space only patch to this file, this patch causes the Makefile.in
6620 files that include freeze.mk to be updated, and thus have a
6621 newer time stamp again, which in turn makes a pristine CVS
6622 checkout have correct time stamps.
6624 * Makefile.maint (cvs-sv): New macro, to be used..
6625 (config.guess-url_prefix, config.sub-url_prefix)
6626 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6627 point to CVS text checkout of Gnulib files.
6628 (copyright-check): Bump current year.
6629 (announcement): Do not hard-wire `./announce-gen'.
6630 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6632 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6634 (wget_files): Update config.guess, config.sub, texinfo.tex by
6635 `wget-update', now that their URLs work again.
6637 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6639 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6640 Problem noted by Paul D. Smith.
6642 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6644 * doc/autoconf.texi: Remove unused words from word list.
6645 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6646 .x-sc_trailing_space: New files.
6648 * doc/standards.texi: Sync from gnulib.
6650 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6651 `LIBOBJDIR' as experimental.
6653 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6654 with a target directory; it's internally implemented as `cp'
6655 anyway, but since Autoconf advertises the possibility to use
6656 a target directory when LN_S is `ln -s', we need to find out.
6657 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6658 analyzed by Keith Marshall <keith.marshall@total.com>.
6662 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6664 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6665 confdefs.h as-is. In general, if it has backslash-newline or the
6666 like, then it doesn't work either to sort or to remove empty
6669 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6671 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6673 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6675 * lib/autom4te.in (Automake-preselections): Preselect
6678 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6680 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6681 apostrophe within a single-quoted string, as this is the usual
6682 tradition and is easier to read than '"'"'. Don't rely on the
6683 shell treating "$/" like '$/'. Use a more-consistent indenting
6686 2006-04-09 Eric Blake <ebb9@byu.net>
6688 * tests/autotest.at (Backquote command substitution),
6689 (Multiline backquote command substitution): Remove mistaken
6690 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6692 (Parenthetical command substitution, Multiline parenthetical
6693 command substitution): here.
6695 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6697 Import macros from gnulib (often changing their name).
6699 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6700 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
6701 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

6707 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6708 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6709 The manual mentions Gnulib more prominently.
6710 * doc/autoconf.texi (Gnulib): New node.
6711 (Pointers): Add Gnulib URL.
6712 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6713 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6715 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6716 suggest a #define rather than a typedef for _Bool, and mention
6717 Gnulib rather than trying to substitute stdbool code.
6718 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6719 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6720 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6721 AC_STRUCT_DIRENT_D_TYPE.
6722 (Particular Types): Mention stdint.h and inttypes.h as standard
6724 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,

6726 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6727 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6728 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6729 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6730 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6731 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6732 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6733 (Coding Style). Don't mention m4_expand_once.
6734 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6735 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6736 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6737 (AC_CHECK_FUNCS): Use it.
6738 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.

6773 _AS_DETECT_BETTER_SHELL:
6775 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

6786 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6787 distinguish m4sugar macros.
6788 * tests/tools.at (autoupdating with aclocal and m4_include):
6789 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6790 test case by Noah Misch <noah@cs.caltech.edu>.
6792 2006-04-07 Stepan Kasal <kasal@ucw.cz>

6804 AS_MKDIR_P exits the script on failure.
6805 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6807 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6826 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6828 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6829 whether `set' quotes correctly: redirect stderr of the tested
6830 `set', and use a subshell, for Ultrix; use `sed' instead of
6831 `grep' for zsh `set' which may write binary output; match only
6832 at the beginning of a line, to avoid false positives.
6833 In order to avoid false positives by unrelated variables with
6834 multiline content, put the dump algorithm in a subshell and
6835 unset all variables containing newlines (except some which are
6836 special to the shell). Warn about cache variables that are

6882 ac_config_<foo>s again, sometimes normalized, sometimes not.
6883 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6884 (AC_CONFIG_COMMANDS): Do not do so here.
6885 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6886 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6887 2005-07-25 rewrite. Noticed by Noah Misch.
6889 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6890 _AC_PRESERVE_HELP_ORDER, ...

6951 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6952 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

7043 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7044 initial `rm' of the candidate files...

7051 no longer needed) by libtool. Make it a cache check.

7053 copied here by mistake.

7678 * doc/autoconf.texi (Installation Directory Variables): Use
7679 our own style advice re 's,a,b,' versus 's|a|b|'. Use "Sed"
7680 rather than "sed" when talking about Sed in general.
7681 (Particular Programs): Likewise.
7682 (Coding Style): y is like s with respect to / and ,.
7683 (Limitations of Usual Tools): Document the weird restrictions
7684 that Posix has about { }. Use better quoting.
7685 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
7686 Rewrite to conform to Posix rules about { } in sed scripts.
7687 * lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.

7705 shell from zsh to bash.
7707 2005-12-31 Stepan Kasal <kasal@ucw.cz>
7709 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
7710 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
7712 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
7714 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced

7748 CONFIG_SHELL in the environment of the configure rerun.
7749 * doc/autoconf.texi (Here-Documents, config.status Invocation):
7750 Suggest passing CONFIG_SHELL absolute, and in the environment
7751 rather than as option.

7769 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7771 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
7772 Factor functionality to..
7773 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7774 `AC_SUBST($1)' in the public version.
7775 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7776 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

7790 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
7791 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.

7795 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
7796 conftst2.$ac_objext.
7797 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7799 2005-10-24 Stepan Kasal <kasal@ucw.cz>
7801 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7802 conftest.o, to see whether the compiler really obeys; rm the object
7803 file before and after the test and register it with ac_clean_files.
7804 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7806 2005-10-21 Stepan Kasal <kasal@ucw.cz>
7808 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
7809 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
7810 code so that the most common case requires less forks.
7812 2005-10-20 Stepan Kasal <kasal@ucw.cz>

7822 the latter'', in two places.
7824 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7826 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7827 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7828 the inner workings of AC_LANG_FUNC_LINK_TRY.
7829 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7830 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7831 by the function rather than ignoring it.
7832 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7833 comparing its address. Intel's interprocedural optimization was
7834 outsmarting the old heuristic. Problem reported by
7837 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7839 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7841 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7843 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7844 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7846 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7848 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7849 before removing it (chmod -R u+rwx); there are three instances of this.
7851 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7852 Stepan Kasal <kasal@ucw.cz>
7854 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7855 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7856 make its content writable before removing it. Remove an errorneous
7857 comment from the end, where the logs of the failed tests are copied
7858 to the main log file.
7860 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7862 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7863 in case the computer is too quick. Double quote the configure.ac
7866 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7867 problems if the testsuite were running too fast.
7869 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7871 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7872 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7873 (which belong to Xt, not X itself). See Debian bug 327655.
7874 * NEWS: Mention this.
7876 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7878 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7880 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7882 * config/move-if-change: Don't output "$2 is unchanged";
7883 suggested by Ben Elliston. Handle weird characters correctly.
7885 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7887 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7888 calls, so that the final expansion of this macro is shorter.
7889 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7890 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7891 the cleanup there. Use AS_VAR_* macros, to be more general.
7892 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7894 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7896 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7898 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7900 * doc/autoconf.texi (Configuration Headers): Add an index entry
7903 2005-08-26 Pavel Roskin <proski@gnu.org>
7905 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7906 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7909 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7911 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7912 The previous patch didn't work, so try a better one.
7914 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7916 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7917 in the example. Reported by Bruno Haible.
7918 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7919 "if $undefined_var;" succeeds with my shell.
7921 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7922 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7923 but change the m4_divert_text to m4_divert_once.
7925 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7927 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7928 Work around bug in Solaris /usr/xpg4/bin/awk.
7929 The bug is present in at least Solaris 8 through 10.
7931 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7933 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7934 some evil values and relying on the fact that $* concatenates the
7935 parameters by the first character from IFS.
7937 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7938 Stepan Kasal <kasal@ucw.cz>
7940 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7941 first header appears, define AH_HEADER.
7942 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7943 Update limitations about when to call AC_CONFIG_HEADERS.
7944 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7945 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7946 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7947 ``Configuration Actions''; fix their index entries.
7949 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7950 options correctly. Process N-M as M-N if M is smaller than N.
7951 Process ranges correctly so that N-N will run only N.
7952 Sort and uniquify the tests that will be run. If there is more
7953 than one test, reinsert the banners for the tests.
7954 * tests/autotest.at (Keywords): Unmark XFAIL.
7956 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7958 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7959 before passing the macro name to AH_TEMPLATE.
7961 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7962 now opens log after option processing; in particular, --version
7963 and --help do not touch config.log.
7965 * Makefile.maint: Revert the change from 2005-08-12.
7967 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7969 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7971 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7973 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7975 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7976 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7979 * doc/autoconf.texi (Defining Symbols, Changed Results):
7980 Prepend to LIBS, not append, in examples.
7982 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7984 When building in place, set srcdir="."; suggested by Tim Van Holder.
7986 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7987 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7988 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7989 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7990 does not mean "no --srcdir option".
7992 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7994 * tests/autoscan.at (autoscan): New file.
7995 * tests/suite.at: Use it.
7996 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7997 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7999 * tests/autotest.at (Keywords): Test keywords combinations.
8001 2005-08-12 Stepan Kasal <kasal@ucw.cz>
8003 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8004 add "2>&1"; gzip 1.2.4 prints help on stderr.
8006 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8008 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8009 was pushdef'ed twice while popped only once. Push it only once.
8010 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8012 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8014 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
8015 prefixed by mere "===", not "configure: === ".
8017 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
8019 * Makefile.maint: Update from Bison.
8021 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8022 "<tab>" in comment, so that the point is understandable.
8024 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8026 Rewrite substantial part of lib/autoconf/status.m4.
8027 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8028 and CONFIG_COMMANDS are not processed in four separate loops.
8029 Instead, there is one main loop. This alows that the common code
8030 is expanded only once, thus config.status (and configure) is smaller.
8032 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8033 the AC_LIST_FILES and cousins macros are no longer used.
8035 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8036 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8037 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8038 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8039 contain the initialization, nor the for loop, nor the associated
8040 commands; all these go to ...
8041 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8042 _AC_OUTPUT_CONFIG_STATUS.
8043 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8044 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8045 (_AC_OUTPUT_FILE): The creation of the sed script ...
8046 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8047 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8048 _AC_OUTPUT_MAIN_LOOP.
8049 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8050 _AC_CONFIG_COMMANDS): Use ...
8051 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8052 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8053 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8054 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8055 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8056 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8058 (_AC_CONFIG_UNIQUE): Update.
8059 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8060 Replaced by this ...
8061 (_AC_LIST_TAGS): ... new common macro.
8062 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8063 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8064 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8065 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8066 this didn't belong to the `config commands' section.
8067 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8068 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8069 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8070 to the `config commands' section either.
8071 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8072 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8074 ... and many changes to the comments nearby.
8076 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8077 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8078 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8079 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8080 (#define header templates): The comment at the top of the generated
8081 header now includes the name(s) of the source file(s).
8083 Several unrelated small changes:
8085 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8086 parameter to AC_DIAGNOSE.
8087 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8088 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8089 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8090 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8092 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8093 in AC_OUTPUT doesn't double-quote it either.
8094 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8097 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8099 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8100 versions of Portland Group compiler produce single- and double-quoted
8101 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8102 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8104 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8106 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8107 This is a corrected version of yesterday's patch.
8109 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8111 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8112 path, too; insert a "===" to emphasize the line.
8114 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8115 ac_cv_build_alias to ac_build_alias.
8116 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8118 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8119 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8120 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8121 (AC_ARG_VAR): ... here.
8122 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8125 Keep a list of all precious variables and process them with one simple
8126 for loop, instead of expanding all commands, or, OTOH, complicated
8127 processing of output of "set".
8128 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8129 variable names in new macro...
8130 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8131 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8132 a loop to assign all ac_env_* and ac_cv_env_* variables.
8133 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8135 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8136 its value to shell variable ac_precious_vars and call
8137 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8138 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call

8185 sed substitution command, so that we allow | in program prefixes
8186 and program suffixes. (& is a problem anyway; we're not fixing

8189 configure_input, top_builddir, srcdir, etc.
8190 * lib/autotest/general.m4 (AT_INIT): Likewise, for

8262 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

8283 variable into diagnostic. Make the diagnostic an error, not a warning,
8284 because we really don't support spaces and suchlike in dir names.
8285 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8286 Don't worry about backslashes in srcdir; it can't happen now.

8305 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8315 (Special Shell Variables): Fix sed code this in the example.
8316 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8317 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

8329 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8330 * doc/autoconf.texi:
8331 Don't mention Solaris versions so much, if a
8332 problem is common to all extant versions of Solaris. Say "SunOS
8333 4" instead of "SunOS" for SunOS 4.
8334 (awk): Mention more of the limitations of traditional Awk.

8351 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8353 * doc/autoconf.texi: "filesystem" -> "file system".
8354 "behaviour" -> "behavior".
8355 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8356 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8358 * lib/m4sugar/m4sh.m4: Likewise.

8375 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8377 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8378 -u, since it outputs chatter if the input files are the same.
8379 Problem reported by Ralf Menzel.
8381 2005-06-08 Derek Price <derek@ximbiot.com>
8383 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8384 renaming them since they are about to be redefined anyhow.
8386 2005-06-08 Derek Price <derek@ximbiot.com>
8388 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8389 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8390 Move m4_undefine to alphabetical order.
8392 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8394 * README: Recommend GNU M4 1.4.3 or later.
8395 * doc/autoconf.texi (Introduction): Likewise.
8396 Reword to avoid some formatting glitches.
8397 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8398 Clarify explanation of HP compiler bug.
8399 Redo example output tp match current CVS snapshot.
8400 Use @example.org in email addresses when the examples
8401 might get inadvertently cut-and-pasted into user code.
8402 Remove example of autom4te usage that doesn't seem to work now.
8403 Use modern AC_INIT (except when the example is meant to be
8404 shown with Autoconf 2.13).
8405 Update ksh info for Solaris 9 and later.
8407 Modernize description of Automake versions a bit.
8408 Don't claim a future version of Autoconf is near.

8414 follows its own advice about quoting better.
8415 Reword to avoid some formatting glitches.
8416 * doc/installt.exi: Reword to avoid some formatting glitches.
8418 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8419 Tru64 ksh pattern matching bug. Reported against Libtool by
8420 Albert Chin <libtool@mlists.thewrittenword.com> and
8421 Nicolas Joly <njoly@pasteur.fr>.
8423 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8425 m4_cdr of one-member list was [[]] (one-member list containing an
8426 empty string) instead of [] (an empty list. Callers were skewed to
8427 match this misbehaviour. As a consequence of this:
8428 - m4_foreach([x], [], [foo]) expanded to `foo', while
8429 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8430 This bug has been fixed:
8432 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8433 expand to an empty string; print error msg if called without
8435 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8436 misbehaviour; handle [] and [[]] correctly.

8444 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8446 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8447 swallow records with more than 99 fields.
8448 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8449 parse the long line.
8451 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8453 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8454 swallow literals longer than 399. Reported by Ralf Wildenhues.
8455 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

8460 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8461 to gfortran, and make these the first two compiler names

8466 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8467 (DISTCLEANFILES): Remove $(check_SCRIPTS).

8474 option. This runs afoul of a limit of 399 bytes per regular
8475 expression on AIX. Problem reported by Ralf Wildenhues.

8488 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8489 now contain newlines, and substituted files must be referenced on
8490 a line alone; the sed scripts to substitute them are now very
8492 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8493 commands can be put in a sed script portably.
8494 * doc/autoconf.texi (Setting Output Variables): Document above

8507 classes in shell scripts. The test was too brittle.
8509 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8511 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

8515 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8517 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out

8525 messages when ac_unique_file is not found.
8526 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.

8543 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8544 (ac_top_builddir): ... this ...

8563 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8564 argument to m4_foreach. I guess it was necessary in the past,
8565 but I think it's a no-op now.

8569 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8570 ``cat <<_ACEOF'' commands to one.

8578 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

8648 * doc/autoconf.texi (Autoconf Language): Be more precise about
8649 quoting rules. Problems noted by Stepan Kasal.
8650 Also, throughout this document, be more careful about white space.
8651 "blank", "white space", and "space" all have different meanings
8652 and we should be careful to say what we mean.

8673 set by latest automake.
8675 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8677 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"

8688 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8691 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8692 by AC_DEFINE; it was a mistake.
8693 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8695 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8697 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8699 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8701 * doc/autoconf.texi (External Software): Quadrigraphs are not
8702 processed correctly in AS_HELP_STRING; avoid this in the examples.
8703 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8704 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8705 comment and reduce m4_default([foo], []) to [foo].
8706 (m4_strip): Update the explanation.
8708 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8710 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

8712 Problem reported by Jennis Pruett.
8713 * lib/autoconf/functions.m4
8714 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

8762 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8763 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8764 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8765 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8766 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8768 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8770 * NEWS: The configure command now warns you if you attempt to use
8771 a directory whose name contains a special character like space,
8773 * doc/autoconf.texi (Installation Directory Variables): Allow
8774 "," in file names. Do not use \@; it's not a portable regexp.

8783 unportable file names.
8784 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8786 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8787 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8788 ac_pwd, and quote srcdir.
8789 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8791 * doc/autoconf.texi: Fix some systematic formatting problems.
8792 ".)" needs a following @: if not at the end of a sentence, and
8793 similarly for "!)". "etc." should be preceded by a comma.
8794 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8796 2005-03-22 Bruno Haible <bruno@clisp.org>
8798 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8799 argument is often called 'build-aux'.
8801 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8803 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the

8810 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8811 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8812 from a Common Lisp's `cl'.
8813 (AC_PROG_CXX): Behave according to the documentation: don't
8814 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8815 make the variable CCC precious; use `cl.exe', not `cl'.
8817 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8818 Alexandre Duret-Lutz <adl@gnu.org>
8820 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8821 /dev/null, as "configure" shouldn't read stdin, and this insulates
8822 us from problems (e.g., when testing for "cl"). Also, do this
8823 redirection before invoking "hostname" or "uname", and keep the
8824 original input stream available via...
8825 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8826 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

8838 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8839 newline if neither \c nor -n work, as that would output two
8840 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8842 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8844 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8845 This causes that any required macros inside will get before the if.
8846 * doc/autoconf.texi (autom4te.cache): A typo.
8848 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8850 Undo previous change, except keep the change to
8851 lib/autoconf/programs.m4 that replaced grep with shell
8852 pattern-matching. This is because net-snmp configure reads stdin.
8853 Reported by Noah Misch.
8855 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8857 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8858 from /dev/null, as "configure" shouldn't read stdin, and this
8859 insulates us from problems (e.g., when testing for "cl").
8860 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8861 before invoking "hostname" or "uname".
8862 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8863 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8864 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8865 "</dev/null" since it's now done at the top of 'configure'.
8866 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8867 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8868 Also, replace grep with shell pattern-matching, to save a process.
8870 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8872 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8873 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8874 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8877 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8879 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8880 grep -q isn't portable. Improve grep -s explanation.
8881 Problem reported by Dan Manthey.
8883 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8885 * doc/autoconf.texi (Special Shell Variables): Clarify
8886 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8888 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8890 * doc/autoconf.texi: Use @acronym for DJGPP.
8891 Fix some @code's that should have been @env's, and vice versa.
8892 Sort environment variable names.
8893 Mention that shells no longer inherit IFS.
8894 Don't recommend PATH_SEPARATOR=';' so strongly.
8895 Mention that $RANDOM might expand to the empty string.
8896 "symlink" and "soft link" -> "symbolic link".
8897 Improve mktemp description (reported by Bruno Haible).
8899 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>

8973 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

9036 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9037 Update the long comment explaining it.
9039 m4_require no longer writes an ``is required by'' line to the
9040 execution stack. It contains only one bit of non-redundant
9041 information: that the macro was required, not called. And even
9042 this bit is useless in most situations: have you ever met a macro
9043 which both calls and requires the same macro?
9045 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9046 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9048 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9049 (m4_expansion_stack_pop): Remove the misplaced comment.
9050 (m4_require): Don't put the ``is required by'' line to the
9051 execution stack; slightly improve the out-of-a-defun error message.
9052 (_m4_divert_grow): New macro, counter for the temporary diversions.
9053 (_m4_require_call): Use it.

9465 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

9526 (Pretty Help Strings): Likewise; remove the wrong comment;
9527 simplify the examples and improve their quoting.
9529 2004-11-13 Stepan Kasal <kasal@ucw.cz>
9531 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9532 the $1_found variable, don't test whether the file is executable;
9533 Both things are checked ...
9534 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
9535 the former ``test -f''.
9536 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
9538 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

9545 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
9546 limitations. Reorder paragraphs for clarity.
9548 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
9550 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9551 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9552 variants", "Unix", and some related minor wording fixups.
9554 (Shellology, Special Shell Variables): Document that the Zsh
9555 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9556 to Alexandre Duret-Lutz for this info.
9558 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>

9567 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
9569 * doc/autoconf.texi (auindex): New macro.
9570 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.

9575 Fix problems reported by Andreas Buening in:
9576 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
9577 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9579 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9580 readable; it's not true in OS/2-emx.
9582 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9584 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9585 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9586 (trivial change). Problem and patch reported by Andrew Church in:
9587 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9589 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

9610 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
9614 * README: Add advice about m4 1.4.2.
9616 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9617 texinfo.tex for now (done by hand now).
9618 * Makefile.maint (wget_files, cvs_files):
9619 Remove ansi2knr.c; nobody uses it.
9620 (ansi2knr.c-url_prefix): Remove.
9621 (cvs-update): Fix test for failure. I don't know why it ever
9624 * doc/autoconf.texi: Update URLs, some of which went stale.
9625 Use @uref rather than @href.
9627 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9628 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9630 * config/config.guess, config/config.sub, config/elisp-comp,
9631 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9632 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9634 * NEWS, TODO, configure.ac, bin/autoscan.in,

9640 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9641 tests/tools.at, tests/torture.at:
9642 Use "file name" rather than "filename" or "path",
9643 to be consistent with the terminology of the GNU coding standards.
9645 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9647 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9648 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9649 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9650 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9652 More fixes to support spaces in the name of the build directory.
9653 This isn't a complete fix but it's an improvement.
9655 * bin/autoconf.as (autom4te_options): New var.
9656 Use it instead of appending to AUTOM4TE, so that we can allow
9657 spaces in the build directory's absolute name.
9658 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9659 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9660 AT_CHECK_NOESCAPE): Likewise.
9661 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9662 main program): Likewise.
9664 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9666 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

9672 * doc/autoconf.texi (Function Portability): Document isinf and
9673 and isnan. From a suggestion by Kevin Ryde.
9675 * lib/Autom4te/General.pm (END): Return correct exit status even
9676 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9678 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9680 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9681 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9682 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9684 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9686 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9687 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9688 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9689 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9690 * lib/autom4te.in (Automake-preselections): Preselect
9691 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9693 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9695 * lib/autom4te.in (Automake-preselections): Preselect
9696 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9699 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9701 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9703 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9704 Document problem with "`""`" in pdksh POSIX mode.
9706 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9708 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9709 with pdksh, too. Problem reported by Patrick Welche via
9711 * doc/autoconf.texi (Shellology): Note that set -o posix is
9712 useful for pkdsh, too.
9714 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9716 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9717 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9718 Don't fail if ENV or BASH_ENV is readonly.
9719 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9720 etc. are read only. Problem reported by Ludovic Courtes.
9722 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9724 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9725 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9728 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9730 * doc/autoconf.texi (File System Conventions): Warn about
9731 names like "aux". Problem reported by Eric Blake.
9733 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9734 by zero instead of array size, so that we can use any arithmetic
9735 constant expression (instead of requiring an integer constant
9736 expression). This allows us to test expressions like DBL_MAX <
9737 LDBL_MAX, which didn't conform to the C standard using the old
9739 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9740 now that we can do floating-point tests at compile time.
9742 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9744 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9745 and LDBL_EPSILON, as the resulting expression isn't an
9746 integer constant expression and violates the C standard.
9747 Problem reported by Nelson H. F. Beebe. Also, check
9748 for "L" suffix, and check that long double doesn't have
9749 worse range or precision than double, that mixed-mode
9750 arithmetic doesn't generate a diagnostic, that double
9751 constants fit in long double.
9753 2004-06-03 Kevin Ryde <user42@zip.com.au>
9755 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9756 malloc(0) and realloc(NULL,size).
9758 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9761 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9763 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9764 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9767 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9769 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9770 can be rewritten using if-then-else. Suggested by Bruno Haible.
9772 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9774 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9775 Problem reported by Stepan Kasal.
9777 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9779 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9780 change). Patch reported by Ralf Wildenhues in
9781 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9783 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9784 function F exists if the compiler and linker let you compile an
9785 expression like (F != 0). Recent versions of GCC optimize away
9786 the reference to F in that case, since every function address must
9787 be nonzero, so the link succeeds even if F does not exist.
9788 Problem reported by Manu in
9789 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9791 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9792 "Unix". Many uses changed.
9793 (Limitations of Builtins): Explain better why the ! command isn't
9796 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9798 * lib/autom4te.in (Automake-preselections): Preselect
9799 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9801 2004-05-19 Kevin Ryde <user42@zip.com.au>
9803 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9804 referencing AC_FUNC_STRERROR_R.
9806 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9807 note pessimistic assumption when cross compiling.
9809 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9811 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9812 (until 2004) invoked subcommands with sh -e, contra POSIX.
9813 Reported by Kevin Ryde.
9815 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9817 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9818 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9819 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9820 `test -f " /usr/bin/grep"', which _always_ failed.
9821 (AC_PROG_SED): Ditto bogus PATH fix.
9822 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9823 requires that grep correctly supports _multiple_ `-e' options, rather
9824 than stating only that grep should accept `-e'.
9826 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9828 Port to C99, which requires that 'exit' be declared.
9830 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9831 to ensure that stdlib.h is included.
9832 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9833 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9834 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9835 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9836 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9837 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9838 when using 'exit' in a test; C99 requires that 'exit' be declared.
9840 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9842 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9843 now prefers 'grep' implementations that accept -e.
9844 (Limitations of Usual Tools): Describe problems of traditional
9845 egrep and fgrep with long input lines, and of traditional grep
9847 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9848 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9849 All callers changed. Append /usr/xpg4/bin to the PATH, for
9851 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9852 the user with complaints about multiple -e options.
9853 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9854 Define it with AC_PROG_GREP.
9855 * configure.ac (AC_PROG_GREP): Add.
9856 * lib/freeze.mk (GREP): New macro.
9858 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9860 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9861 a possible candidate only after all others fail, rather than
9862 consulting it first. This improves backward compatibility by
9863 better reflecting the way shell selection occurred in previous
9864 versions of Autoconf, and should help to avoid triggering latent
9865 problems in other packages, such as the one in Automake where zsh
9866 is not handled robustly:
9867 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9868 Although it is not Autoconf's responsibility to work around
9869 problems in Automake, it nevertheless makes sense to avoid
9870 introducing unnecessary incompatibilites.
9872 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9873 Gary V. Vaughan <gary@gnu.org>
9875 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9876 how deeply nested we are when a suitable tool is found, set the
9877 ac_path_TOOL_found flag.
9878 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9879 nested we are in this macro. Break out of all 3 nested loops if
9880 ac_path_TOOL_found is set.
9882 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9884 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9885 of the _AS_PATH_WALK loop too if GNU flavor is found.
9887 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9889 * doc/autoconf.texi (Limitations of Make): Update documentation
9890 for `$<'. New entry `Long lines', based on a report from Simon
9891 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9892 paragraph about DJGPP, based on a mail from Richard Dawe.
9894 2004-04-20 Paul Eggert <eggert@twinsun.com>
9896 * tests/c.at (C keywords): Don't assume that GCC supports
9897 "restrict" and "inline", as sufficiently-old GCC versions do not
9898 (also, GCC configured to be in pedantic C89 mode does not).
9899 Problem reported by Sumit Pandya in:
9900 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9902 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9903 consider -g to work if it generates warnings when plain compiles
9904 don't. Problem reported by Braden McDaniel in:
9905 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9907 * doc/autoconf.texi (Slashes): New section, to document a problem
9908 reported by Jim Meyering in:
9909 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9911 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9912 linker output files before linking, to work around IRIX 6 linker bug.
9913 Problem reported by Rainer Orth in:
9914 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9916 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9918 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9919 best tool so far counter rely on the tool path variable name to
9920 avoid checks for one tool being affected by the results of running
9921 the length check on a previous tool.
9923 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9924 match expression argument, as different greps have different
9925 regular expression flavours.
9926 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9928 (AC_PROG_EGREP): Pass 'EGREP$'.
9929 (AC_PROG_GREP): Pass 'GREP$'.
9931 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9933 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9934 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9936 2004-03-29 Paul Eggert <eggert@twinsun.com>
9938 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9939 Types, Specific Compiler Characteristics, System Services,
9940 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9941 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9942 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9943 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9945 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9946 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9947 AC_TYPE_OFF_T): Likewise.
9948 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):

9952 pacify libtool 1.5.2. Fix quoting problems in sed command.
9954 2004-03-28 Paul Eggert <eggert@twinsun.com>
9956 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9957 now defines HAVE_DECL_TZNAME if it is declared, when
9958 HAVE_STRUCT_TM_TM_ZONE is not defined.
9959 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9960 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9963 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9965 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9966 superfluous backslashing of quotes (") in sed expressions;
9967 thanks to Paul Eggert.
9969 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9971 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9972 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9973 H. F. Beebe for the bug report.
9975 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9977 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9978 quoted -cmdline argument in Portland Group compiler (bug
9979 reported by Jeffrey J. Barteet).
9981 2004-03-25 Kevin Ryde <user42@zip.com.au>

10012 * doc/autoconf.texi: Avoid macros with unbraced arguments,

10029 * bin/Makefile.am (edit): Don't use $< in a context where
10030 POSIX doesn't require support for it. Use $@.in instead.

10048 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10049 problem on QNX reported by Stephen Rasku in

10052 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10053 $(m4sh_m4f_dependencies); this removes a FIXME.
10054 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.

10061 AC_SUBST provides no portable way to escape literal newlines.
10063 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10064 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10065 Darwin uses -lcrt2.o and there's little point to cataloging all
10066 the system variants. Partial fix reported by Andreas Waechter in:

10092 Paul Eggert <eggert@twinsun.com>
10094 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

10096 parameter. Expand _AS_SHELL_FN_SPY.

10109 trigger the bash bug anymore.
10110 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10111 use AS_INIT_WITH_SHELL_FN.
10112 * bin/autoconf.in, tests/wrapper.in: Regenerated.

10142 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

10144 the 2003-05-22 change, which removed the older years from the list.
10145 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

10158 _AC_PROG_GREP, and AC_PROG_SED.
10159 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10160 longest input length accepted by a command.

10191 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10192 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10193 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10194 not <inttypes.h>. Problem reported by Tim Mooney in
10195 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10196 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10199 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10200 otherwise "make check" fails because it forbids cmp (I guess
10201 because cmp treats files as binary on DOS-like systems).
10203 * tests/mktests.sh: Update copyright date to 2004, since some tests
10204 have changed in 2004.
10206 2004-01-23 Gary V. Vaughan <gary@gnu.org>

10214 2004-01-15 Paul Eggert <eggert@twinsun.com>
10216 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10217 -std1 disables some useful extensions on Tru64. Problem reported
10218 by N. Lichtmaier in

10221 2004-01-14 Paul Eggert <eggert@twinsun.com>
10223 * doc/autoconf.texi (Programming in M4sh): Document that
10224 AS_MKDIR_P succeeds if the destination is a symbolic link
10225 to an existing directory.
10226 (Limitations of Usual Tools): Note that mkdir -p might not
10227 succeed on symlinks to directories.
10229 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10231 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10232 * bin/autoheader.in: Grammar fix in message.
10233 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10234 Test for dir before calling mkdir -p. (trivial changes)

10241 2004-01-10 Jim Meyering <jim@meyering.net>

10245 2004-01-09 Paul Eggert <eggert@twinsun.com>
10247 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10248 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10249 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10250 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10251 AC_COMPILE_IFELSE, since we now assume our caller invokes
10252 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10253 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10254 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10255 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10257 2004-01-07 Paul Eggert <eggert@twinsun.com>
10259 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10260 `"'...'"`, as it's confusing (and I suspect it may not work on
10261 some platforms). The code was incorrect anyway, as it assumed
10262 that \$ evaluated to itself in that context. Reported by
10263 Alexandre Duret-Lutz.
10265 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10267 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10268 and _LT_AC_TAGCONFIG.

10295 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10296 Use "rm -f" to remove conftest.sed, not plain "rm".
10297 Bug reported by David Relson in
10298 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10300 * Makefile.am (autom4te-update):
10301 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

10317 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10318 -c -o might not work. From a suggestion by Kevin Ryde.
10319 (C Compiler, Generating Sources, Limitations
10320 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10321 Don't put '-o' after non-options, as POSIX doesn't allow this.
10322 Mention that cc's name might be gcc or c89 or whatever.
10324 2004-01-04 Kevin Ryde <user42@zip.com.au>
10326 * doc/autoconf.texi: Add various further index entries.

10335 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10336 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

10338 explanation clearer.

10349 * tests/atlocal.in: Store the result here.
10350 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

10352 of explicitly testing.
10353 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10354 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10355 * tests/tools.at (Syntax of the shell scripts): Simplify

10440 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10441 than $target since the latter is not usual, add guidelines on when to
10442 use or not use the system type.

10604 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
10606 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official

10619 Problems reported by Eric Sunshine.
10621 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
10623 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10624 -mGLOB_options_string stuff for Intel ifc, which can cause

10648 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10649 cache variable instead of $G77 to decide whether to include -O2,
10650 since $G77 is specific to Fortran 77.

10654 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10655 free" flag. Re-order flags tested into rough order of popularity.
10657 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10659 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10660 arguments so that it can be used with syntax identical to
10661 AC_PROG_F77, and so that we can more easily decide to
10662 remove/deprecate the DIALECT optional argument in the future if it
10663 proves troublesome.
10664 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10665 non-freeform-supporting compilers. Document freeform flags.
10667 2003-10-03 Akim Demaille <akim@epita.fr>

10729 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10730 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10731 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

10734 2003-09-26 Akim Demaille <akim@epita.fr>
10736 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10737 directory for AC_CONFIG_COMMANDS' first argument exists.
10738 This makes valid the invocation of _AC_SRCPATH that follows.
10739 Reported by Eric Sunshine.
10740 * doc/autoconf.texi (Configuration Commands): Adjust.
10742 2003-09-26 Akim Demaille <akim@epita.fr>

10763 The test suite are sometimes assigning timings incorrectly.
10764 Reported by Henk Krus.
10765 Diagnosed by Nicolas Joly.
10767 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10769 Instead of making AT_help a sequence of assignments to grow
10770 $at_help_all, just make AT_help_all be the growing contents of
10771 $at_help_all, and make a single assignment in...
10773 (at_times_skip): Flip the meaning and rename as...
10774 (at_times_p): this.
10775 (AT_INIT): When summarizing the test that ran, remove

10785 (ifnames): chmod -w.
10786 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10787 executables, not bin/ executables! Otherwise all the magic needed
10788 to find non installed files is turned off. This caused a failure
10789 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10790 as found in its environment (sent by tests/autoreconf): pointing
10791 to bin/autom4te that could not find its files.
10792 * tests/mktests.sh: Force the replacement of generated files, for
10793 the sake of "mv" program that are interactive when overwriting a
10795 * config/install-sh: Upgrade from CVS Automake.

10802 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10803 Paul Eggert <eggert@twinsun.com>
10805 Trivial change to support GCC's configuration procedure.

10841 willing to edit the output files.
10843 2003-09-10 Akim Demaille <akim@epita.fr>

10846 and AC_FC_FREEFORM.
10847 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10848 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

10888 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10890 Add support for newer Fortran dialects. The F77 interface is
10891 unchanged, and continues to support Fortran 77. New FC macros
10892 correspond to all the old F77 macros, with output variables FC,
10893 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10894 available dialect, but older dialects can be specified. There are
10895 new macros AC_FC_SRCEXT to set the source extension, and
10896 AC_FC_FREEFORM to accept free-form source files.
10898 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

11022 2003-08-21 Akim Demaille <akim@epita.fr>
11024 First stab at preserving warnings between calls to autom4te,
11025 including when the cache is used.
11027 There are still several issues: (i) there are too many runs of m4
11028 (one for include, one for warnings, and some more), (ii) warnings
11029 spreading on several lines are not handled gracefully, (iii) the
11030 code meant to have the call stack display for errors does not work
11031 (its handling should move from m4 to autom4te).
11033 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11035 (@preselect): Add m4_warn.
11036 ($exit_status): Remove, use $exit_code.
11037 ($help): Use Autom4te::ChannelDefs::usage.
11038 (&handle_m4): No longer define the m4_warnings.
11039 At each run, extract and report the warnings.
11040 Always cache the result, including if the exit status is on
11041 failure, since if nothing changes, we should result in the same
11042 failure, hence we can use the cache.
11043 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11044 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11046 (m4_warn): Redefine as a do-nothing: it is its invocation that
11047 matters, as warnings are now reported via traces.
11048 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11049 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11050 the latter reveals calls to the former.
11054 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

11083 Reported by Alexandre Duret-Lutz.

11087 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11088 * bin/autom4te: Adjust.
11089 In particular, be Autoconf tools are really silent when properly
11090 working, bind the verbosity of the 'note' channel to $verbose.
11091 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

11215 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11216 not all of them. This fixes 1. the fact that when testing
11217 Autoconf there are many many config.log, 2. the incorrect use of
11218 top_srcdir to find config.log.
11219 Don't mix the detailed output of failed test with the summary of
11220 failures. Rather, append detailed log afterwards.
11222 2003-06-23 Akim Demaille <akim@epita.fr>
11224 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

11339 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11340 Remove `#include <stdlib.h>' from the list; we should never
11341 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11342 resulting namespace pollution would cause other tests to fail.
11343 Configure scripts run with some older versions of g++ and HP's
11344 aCC would fail due to such an #include. Problems reported by
11345 Matthew Mueller in <http://bugs.debian.org/120704> and by
11347 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11348 In the test, use the test declaration before including <stdlib.h>,
11349 as that's closer to how it'll be used.

11356 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11358 Overhaul Autotest's logging: generate separate log files
11359 in testsuite.dir/NNN/testsuite.log, and append them to
11360 testsuite.log instead of re-running the test verbosely.
11362 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11363 file descriptor, write 0 to at_status_file instead of setting
11364 at_status=0, initialize some new variables (at_status_file,
11365 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11366 to rerun the tests, instead append the at_group_log to the
11367 at_suite_log when a test fails.
11368 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11369 with the AS_MESSAGE_LOG_FD redirected to stdout.
11370 (AT_CLEANUP): save the output status in $at_status_file
11371 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11372 its original place.
11373 (AT_CHECK): since tests are run with a redirected stdout,
11374 and used to be re-run in verbose mode, turn some $at_verbose
11375 into echo, and don't redirect the output of testing stdout
11378 * lib/autotest/autoconf.texi (testsuite Scripts): Update

11499 2003-05-06 Akim Demaille <akim@epita.fr>
11501 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11502 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11503 by aclocal.m4 is changed it might require the importing of another
11504 m4 extension file, i.e., aclocal must be run.

11777 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11778 defined, to support freestanding compilers. This should fix the
11779 bug reported by Momchil Velkov in

11782 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

11818 * Makefile.maint: Sync with Bison, i.e.:
11819 (po-check): Scan .l and .y files instead of the

11882 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11884 We _have_ to stop using the old compatibility scheme that tried to
11885 avoid useless backslashes because Libtool 1.4.3 contains a
11886 AC_DEFINE([error_t], [int],
11887 [Define to a type to use for \`error_t' if it is not
11888 otherwise available.])
11889 We _have_ to quote the single quote and backslashes with \. The
11890 old compatibility scheme saw that ` was backslashed, and therefore
11891 did not quote the single quote. Hence before this patch, Autoconf
11892 was not compatible with Libtool.

12346 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12347 aclocal invocation, as Gettext macros might not be visible to

12384 users who use config.site to require for a cache: in this case,
12385 the two last configure runs, using two different sets of
12386 arguments, trigger a legitimate error.
12388 2002-09-28 Akim Demaille <akim@epita.fr>
12390 * tests/m4sh.at (Functions Support, Functions and return Support):
12393 2002-09-28 Akim Demaille <akim@epita.fr>
12395 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12396 autoheader are Perl programs.
12397 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12398 (autom4te): Specify that the sources are in the $srcdir.

12404 (tm_zone): Move their rules to...
12405 * lib/autoconf/types.m4: here, using AN_ macros.
12406 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12407 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

12421 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12422 (.m4.m4f): Don't pass --prepend-include, since that's done by
12423 tests/autom4te itself.
12424 * lib/autoscan/Makefile.am: Include freeze.mk.
12425 (autoscan.list): New target --this file is no longer a source.
12426 (autoscan.pre): New file.
12428 2002-09-28 Akim Demaille <akim@epita.fr>
12430 * bin/autoscan.in (@kinds): Make them singular.
12432 (&init_tables): When --debug, report the list of rules to ease
12433 tracking changes in autoscan.list.
12434 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12436 2002-09-28 Akim Demaille <akim@epita.fr>
12438 * lib/autoscan/functions, lib/autoscan/headers,
12439 * lib/autoscan/identifiers, lib/autoscan/makevars,
12440 * lib/autoscan/programs: Merge into...
12441 * lib/autoscan/autoscan.list: this.
12442 * bin/autoscan.in (&init_tables): Adjust.
12444 2002-09-28 Akim Demaille <akim@epita.fr>
12446 * lib/autoscan/functions, lib/autoscan/headers,
12447 * lib/autoscan/identifiers, lib/autoscan/makevars,
12448 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12449 `functions' line is now prefixed with `function:'.
12450 * bin/autoscan.in (&init_tables): Adjust.
12452 2002-09-28 Akim Demaille <akim@epita.fr>
12454 From now on, autoscan files must always map a macro name to a
12455 word: there is no `default' macro for autoscan.
12457 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12459 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12462 2002-09-28 Akim Demaille <akim@epita.fr>
12464 * bin/autoscan.in (%c_keywords): Remove.
12465 (&used): Keep only track of the words we might be interested in.
12466 (&output_kind): It is no longer needed to look for non active
12469 2002-09-27 Akim Demaille <akim@epita.fr>
12471 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

12480 Thanks to Bill Moseley and Paul Eggert.
12481 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12482 the tmpdir must be created.
12483 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12484 dir be in the build tree, instead of $TMPDIR.
12486 2002-09-27 Akim Demaille <akim@epita.fr>
12488 * bin/autoscan.in: Improve the comments.
12489 (&parse_args): Drop obsolete undocumented options.

12497 Reported by Ralf Corsepius.
12498 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12500 2002-09-26 Akim Demaille <akim@epita.fr>
12502 Single suffix rules and seperated dependencies are not portable.
12504 * doc/autoconf.texi (Installation Directory Variables): Update.
12505 (Limitations of Make): Some about `Single Suffix Rules and
12506 Separated Dependencies'.
12507 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12508 (ifnames, autoscan, autom4te): Un-factor into several rules.
12510 2002-09-25 Paul Eggert <eggert@twinsun.com>
12512 * BUGS (Interoperability bugs): New section. Mention libtool
12513 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12515 2002-09-24 Paul Eggert <eggert@twinsun.com>
12517 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12518 make handles suffix-rules differently from GNU make.
12520 * bin/Makefile.am (SUFFIXES, .in): Remove.
12521 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12522 Move the body of the old .in rule here.
12524 2002-09-16 Akim Demaille <akim@epita.fr>
12526 i960 compilers create `b.out' files by default.
12527 Reported by Ralf Corsepius.
12529 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12530 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12532 2002-09-13 Paul Eggert <eggert@twinsun.com>
12534 * doc/autoconf.texi (Particular Headers): Remove obsolete
12535 reference to `struct timezone' in the description of
12538 2002-09-13 Akim Demaille <akim@epita.fr>
12542 * config/config.sub, config/config.guess: Update.
12543 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12544 * Makefile.am: Adjust.
12546 2002-09-13 Akim Demaille <akim@epita.fr>
12548 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12549 reading config.log when the compiler is rejected.
12550 Suggested by Guido Draheim.
12552 2002-09-13 Akim Demaille <akim@epita.fr>
12554 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12555 (chdir_init) might hang when stat'ing mounted directories.
12556 Reported by Vance Shipley.
12558 2002-09-12 Akim Demaille <akim@epita.fr>
12560 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12563 2002-09-12 Akim Demaille <akim@epita.fr>
12565 * doc/autoconf.texi (Defining Symbols): Present two different
12566 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12567 difference between 1 argument calls, and 2-3 argument calls.
12569 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12571 * doc/autoconf.texi: Review grammar and punctuation.
12573 2002-09-11 Paul Eggert <eggert@twinsun.com>
12575 * doc/autoconf.texi: Fix minor formatting, spelling, and
12577 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12578 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12581 2002-09-11 Akim Demaille <akim@epita.fr>
12583 * doc/autoconf.texi (Questions): Rename as...
12585 (Defining Directories): New.
12587 2002-09-09 Akim Demaille <akim@epita.fr>
12589 * doc/autoconf.texi (Making testsuite Scripts): Update.
12590 Suggested by Nishio Futoshi.
12592 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12594 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12595 plain `@' is wanted.
12597 2002-09-09 Akim Demaille <akim@epita.fr>
12599 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12600 `duplicates', since the algorithm was too naive and could keep
12601 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12602 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12603 Reported by Ralf Corsepius.
12604 * tests/torture.at (Configuring subdirectories): Exercise these
12607 2002-09-09 Akim Demaille <akim@epita.fr>
12609 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12610 looking for a replacement file.
12611 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12612 directory is relative.
12613 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12614 directory definition.
12615 Reported by Andreas Schwab and Jim Meyering.
12617 2002-09-06 Akim Demaille <akim@epita.fr>
12619 * doc/autoconf.texi (Setting Output Variables): Clarify what
12620 precious variables are.
12621 Suggested by Pontus Skoeld.
12623 2002-09-05 Akim Demaille <akim@epita.fr>
12625 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12626 (ifnames, autoscan, autom4te): Since we don't only depend on
12627 configure.ac variables (such as VERSION etc.), but also on prefix
12628 and so forth, depend on Makefile, not configure.ac.
12629 Reported by Alexandre Duret-Lutz.
12630 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12632 2002-09-05 Kevin Ryde <user42@zip.com.au>
12634 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12635 doesn't seem to be confined to ia64, just say "some versions".
12637 2002-09-04 Akim Demaille <akim@epita.fr>
12639 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12641 * Makefile.am (maintainer-clean-local): Remove.
12642 (MAINTAINERCLEANFILES): Remove COPYING.
12644 2002-09-03 Paul Eggert <eggert@twinsun.com>
12646 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12647 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12650 2002-09-03 Akim Demaille <akim@epita.fr>
12652 * configure.ac: Bump to 2.53d.
12653 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12654 as of today, on Automake's team suggestion.
12656 2002-09-03 Akim Demaille <akim@epita.fr>
12660 2002-09-02 Akim Demaille <akim@epita.fr>
12662 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12664 * configure.ac: Disable SITE_MACRO_DIR.
12666 2002-09-02 Jim Meyering <meyering@lucent.com>
12668 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12669 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12670 Also, tweak grammar: s/make sure to/be sure to/.
12672 2002-09-02 Paul Eggert <eggert@twinsun.com>
12674 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12675 directory names are generally preferable to physical names.
12677 2002-09-02 Akim Demaille <akim@epita.fr>
12679 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12680 Reported by Raja R. Harinath.
12681 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12682 * bin/autoupdate.in: Use error instead of die.
12684 2002-09-01 Paul Eggert <eggert@twinsun.com>
12686 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12687 ordinary shell concatenation rather than echo+tr+sed command that
12688 runs afoul of a long-line-related sed bug in Solaris 8.
12690 * bin/autoheader.in (parse_args): --warning -> --warnings.
12692 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12693 stdout, as traditional "ls" does.
12694 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12695 _AC_COMPILER_EXEEXT_O): Likewise.
12696 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12698 * bin/autoconf.as: Add --prepend-include option. This patch was
12699 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12700 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12702 * bin/autoconf.in, configure: Regenerate.
12704 * doc/autoconf.texi (Special Shell Variables): Mention
12705 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12707 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12708 MAILPATH and set PS1, PS2, PS4 to default values, to work
12709 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12710 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12711 the Autoconf documentation specifies; fall back to "unset" only if
12712 this fails. Use a shell for-loop for this rather than an m4 loop,
12713 to shorten the output script.
12715 2002-08-30 Paul Eggert <eggert@twinsun.com>
12717 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12718 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12719 for the CDPATH problem. Document PWD.
12720 (Limitations of Builtins): Document the problem that "cd $foo" and
12721 "ls $foo" may refer to different directories in shells conforming
12722 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12723 example, since the old example is now out of date.
12725 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12726 FOO" and "ls FOO" talk about different directories; this catches
12727 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12730 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12731 of rolling our own unset.
12732 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12733 in practice we needn't worry about CDPATH if unset doesn't work.
12735 * Makefile.in, aclocal.m4, bin/Makefile.in,
12736 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12737 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12738 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12739 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12740 tests/Makefile.in: Regenerate with Automake 1.6.3.
12742 * config/config.guess, config/config.sub, config/mkinstalldirs:
12745 * configure: Regenerate with self.
12747 2002-08-30 Kevin Ryde <user42@zip.com.au>
12749 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12752 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12754 * bin/autom4te.in (Request::load): Correctly test for "do" read
12757 2002-08-29 Akim Demaille <akim@epita.fr>
12759 * lib/Autom4te/General.pm (&xqx): New.
12760 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12761 hand, which is not portable.
12763 * bin/autom4te.in: Use them.
12764 Use &error instead of die.
12765 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12768 2002-08-17 Paul Eggert <eggert@twinsun.com>
12770 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12771 default list of compilers to try, since it was long ago superseded
12772 by the ksh fc builtin. Suggested by Steven G. Johnson.
12774 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12776 * doc/autoconf.texi (Invoking autom4te): End the option table,
12777 fixing a bug introduced by the previous patch.
12778 (Limitations of Make): Add a 'target lookup' subentry in the
12779 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12781 2002-07-29 Mark D. Roth <roth@feep.net>
12783 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12784 options and use $AUTOM4TE_PATH.
12785 * doc/autoconf.texi: Remove documentation of autom4te
12786 --include-envvar and --site-macro-subdir options and document
12787 use of $AUTOM4TE_PATH.
12788 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12789 arguments from each language section.
12791 2002-07-29 Paul Eggert <eggert@twinsun.com>
12793 * doc/install.texi: Include copyright symbol in copyright notice.
12795 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12797 (AM_MAKEINFOFLAGS): New macro.
12798 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12799 * Makefile.am (INSTALL): Use the new macros.
12800 Use -o rather than --output, since "missing" does not grok --output.
12802 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12804 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12805 comments do not always work. Never trust the exit status of
12808 2002-07-24 Kevin Ryde <user42@zip.com.au>
12810 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12811 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12813 2002-07-23 Paul Eggert <eggert@twinsun.com>
12815 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12816 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12817 apparently treats PATH="nonexistent" as if it contained ".".
12818 Bug reported by Stefan `Sec' Zehl.
12820 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12822 * doc/autoconf.texi (Limitations of Make): Mention the special
12823 handling of the obj/ directory by BSD make.
12825 2002-07-20 Kevin Ryde <user42@zip.com.au>
12827 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

12857 Alexandre Duret-Lutz <duret_g@epita.fr>
12859 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
12860 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
12862 2002-07-17 Russ Allbery <rra@stanford.edu>
12864 * doc/autoconf.texi (Initializing configure): Clarify the
12865 description of the tarname default.
12867 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
12869 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12870 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12871 latter was not run.
12873 2002-07-17 Akim Demaille <akim@epita.fr>
12875 * lib/Autom4te/General.pm (find_file): Browse the directories in

12944 2002-06-27 Paul Eggert <eggert@twinsun.com>
12946 * config/install-sh: Quote $src. Prefer || to test's -o option,
12947 as per "Limitations of Builtins".

13088 This improves on an earlier suggestion by H. Peter Anvin.
13090 2002-05-16 Paul Eggert <eggert@twinsun.com>
13092 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13093 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13094 Both macros now accept an optional source-dir arg.
13095 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13097 * NEWS: Document this.
13098 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13100 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13101 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13102 not for GNU extensions; this undoes part of the 2000-11-03 change,
13103 reverting to 2.13-compatible behavior.

13111 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13112 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13113 and it causes a 'test' syntax error if it fails.
13114 Bug reported by Stephen Gildea.
13116 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13117 If prototypes are supported, use them to check this at compile-time,
13118 instead of trying to check it at run-time. If we must do a run-time
13119 check, assume that setvbuf is standard when cross-compiling, as
13120 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13121 Bug reported by Paul D. Smith.
13123 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13124 argument specifying location of getloadavg.c. This removes a
13125 FIXME. This idea was taken from Jim Meyering's implementation in
13127 * doc/autoconf.texi (Particular Functions): Document this.
13128 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13129 that's what the code does; this fixes a bug reported by
13132 2002-05-03 Akim Demaille <akim@epita.fr>
13134 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13135 autopoint instead of gettextize.
13136 ($uses_alocal): Rename as...
13137 ($uses_aclocal): this.
13138 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13139 Suggested by Bruno Haible.
13141 2002-05-03 Akim Demaille <akim@epita.fr>
13143 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13145 2002-04-29 Paul Eggert <eggert@twinsun.com>
13147 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13148 files to be 1 second older; just set them to be the same time.
13149 Also, sleep 1 second after the first aclocal, to work around
13150 problems with sub-second time stamps on the input files.
13152 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13154 * doc/autoconf.texi: Mention "set -e -x" lossage
13155 under node "Limitations of Builtins".

13161 From Christian Cornelssen.
13163 2002-04-29 Akim Demaille <akim@epita.fr>
13165 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13166 of lack of $LINENO support, then the test will compare the $LINENO
13167 in testsuite vs. the lineno in the test file. This is wrong, of
13169 Be sure to protect it.
13170 Reported by Patrick Welche.
13172 2002-04-25 Akim Demaille <akim@epita.fr>
13174 * doc/autoconf.texi (Obsolete Macros): Typo.
13175 Reported by Vladimir Volovich.
13177 2002-04-25 Akim Demaille <akim@epita.fr>
13179 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13180 than some of the input files, hence, on the second run of aclocal,
13181 if some of its input are younger, make them older.
13182 Suggested by Paul Eggert.
13184 2002-04-25 Akim Demaille <akim@epita.fr>
13186 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

13192 and ac_subst_vars be sh variables containing the list of
13193 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13195 (_AC_INIT_PREPARE): Use them to log them.
13196 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13197 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13198 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13199 _AC_SUBST_FILES and _AC_SUBST_VARS.
13200 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13202 2002-04-24 Akim Demaille <akim@epita.fr>
13204 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13205 autoheader, so that automake does not complain about a missing
13206 config.h.in that was to be created.
13208 2002-04-23 Akim Demaille <akim@epita.fr>
13210 * bin/autoheader.in (parse_args): --warning takes an argument.

13355 Reported by Ezra Peisach.
13357 2002-04-04 Andreas Schwab <schwab@suse.de>
13359 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13360 contains no literal separators.
13362 2002-04-03 Akim Demaille <akim@epita.fr>
13364 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13365 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13366 Use dnl, not the KILL diversion.
13368 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13369 (AC_CONFIG_LINKS): here.
13371 Don't use the KILL diversion, as it kills spurious output, which
13372 results in failures being hidden.
13373 Use m4_defn where appropriate.
13374 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13375 after the second argument.
13377 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13378 syntax, as it is provided by M4sugar.
13379 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13381 2002-04-03 Andreas Schwab <schwab@suse.de>

13395 (_AC_COMPILER_OBJEXT): Use them.
13396 Fixes Debian #138666.
13398 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13400 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13402 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13403 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13404 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13405 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13406 (AC_C_CONST): Same.

13420 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13421 to avoid versions of HP C which don't allow that.
13423 2002-03-27 Paul Eggert <eggert@twinsun.com>
13425 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13426 (AS_SHELL_SANITIZE): Invoke it.

13435 * doc/autoconf.texi (Introduction): The GNATS base moved.
13437 2002-03-25 Paul Eggert <eggert@twinsun.com>
13439 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13440 as POSIX requires, as it doesn't work with Zsh.
13441 * doc/autoconf.texi (Assignments): Document the problem.
13443 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13445 * doc/autoconf.texi (Limitations of Make): Mention more issue
13446 about VPATH, overriding of macros in sub-makes, and handling of
13449 2002-03-21 Paul Eggert <eggert@twinsun.com>
13451 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13452 problem with here-document buffer boundaries.
13454 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13455 when reinvoking the shell, to work around problems with installers
13456 who put strange things like "cd" commands in their environments.
13458 2002-03-19 Akim Demaille <akim@epita.fr>

13476 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

13480 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13481 (Limitations of Usual Tools): Add mkdir section.
13483 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13484 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13485 back on AS_DIRNAME to compute prefixes otherwise; this is
13486 roughly what mkinstalldirs does. That way, we need not have
13487 our own filename disassembler. The old disassembler did not
13488 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13490 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13491 Create at_test_all by a series of assignments,
13492 not by a single assignment of a long string. The latter causes ksh
13493 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13494 presumably because of a buffer overrun.
13496 2002-03-14 Paul Eggert <eggert@twinsun.com>
13498 * lib/autotest/general.m4 (at_times_skip):
13499 Renamed from at_times. Now a boolean.
13500 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13501 says 'times: not found'.
13503 2002-03-14 Akim Demaille <akim@epita.fr>
13505 * bin/autoreconf.in (&study_gettextize): New.
13506 (&autoreconf): Handle newest gettextize.
13507 Rerun aclocal if needed.
13508 Suggested by Andreas Schwab.

13517 Add information about stdint.h and inttypes.h from Paul Eggert.
13519 2002-03-13 Akim Demaille <akim@epita.fr>

13530 2002-03-11 Andreas Schwab <schwab@suse.de>
13532 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13533 does not do it if --with-lispdir is given.

13542 subdirectory should exist.
13544 2002-03-08 Akim Demaille <akim@epita.fr>
13546 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13548 2002-03-08 Akim Demaille <akim@epita.fr>
13550 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13551 aliases the actual variables, and modifications of the former
13554 2002-03-08 Akim Demaille <akim@epita.fr>
13556 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13557 because of C-c: have m4 output in tmp files, then mv them.

13580 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13581 * lib/autoconf/general.m4 (AC_INIT): More informative error
13582 message for LIBOBJ.
13584 2002-03-04 Akim Demaille <akim@epita.fr>

13589 2002-03-04 Akim Demaille <akim@epita.fr>
13591 * doc/autoconf.texi (Transforming Names): Equality between target
13592 and host is irrelevant.
13593 (Specifying Names, Canonicalizing): Remove all references to the
13594 backward compatibility hooks. Rather, collect them all into...
13595 (Hosts and Cross-Compilation): this new section.
13596 * doc/install.texi (System Type): Ditto.
13597 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13598 that `--host' implies cross-compilation.
13600 2002-03-04 Akim Demaille <akim@epita.fr>
13602 * doc/autoconf.texi (Evaluation Macros): New.
13603 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13605 (_m4_foreach): Define the variant with immediate evaluation so
13606 that it contains exactly the items, not an expression which
13607 evaluation is the current item.
13608 (m4_re_string, m4_re_word): Don't over quote them.
13610 2002-03-04 Akim Demaille <akim@epita.fr>
13612 Instead of having stacking `shift's evaluated at the end, let
13613 `foreach' loops immediately evaluate them.
13615 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13616 $*. This is the n-th time I change my mind, but hopefully this is
13619 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13621 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13622 it was only a hack for m4_text_wrap.
13623 (m4_car2): Remove, replaced by...
13625 (_m4_foreach): Adjust.
13626 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13627 m4_bpatsubst for clarification.

13678 Fix Autoconf PR/207:
13679 AC_PREFIX_PROGRAM fails with dashed program names
13681 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

13718 2002-02-05 Akim Demaille <akim@epita.fr>
13720 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13743 optional are the sum of the previous files on the command line'.
13744 Also, pass `--reload-state=' on them, so...
13745 (handle_m4): don't.
13746 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13747 (M4sh): Rely on M4sugar.
13748 (Autotest, M4sh, M4sugar): Use frozen files.

13778 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13780 2002-01-28 Akim Demaille <akim@epita.fr>
13782 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13785 2002-01-28 Akim Demaille <akim@epita.fr>
13787 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13788 AUTOTEST_PATH *after* it was set.
13789 Don't put `.' in the PATH: the user should be precise and `./' if
13790 needed. In addition, given that the test suite does some `cd', if
13791 `.' is in the path, the `tested programs' sections will report
13792 programs found in the test suite's directory, while during the
13793 tests (performed in their own directory), these programs are no
13794 longer visible. In other words, the results is confusing and

13868 2002-01-06 Akim Demaille <akim@epita.fr>
13870 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13871 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13872 and PACKAGE_BUGREPORT from here...
13873 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13875 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13876 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13877 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13878 * tests/tools.at (autoheader): Adjust.
13879 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13881 2002-01-06 Akim Demaille <akim@epita.fr>
13883 * bin/autoscan.in (scan_file): Use `&used'.
13885 2002-01-03 Akim Demaille <akim@epita.fr>
13887 * doc/autoconf.texi (Output): Improved wording regarding use of
13891 2001-12-18 Kevin Ryde <user42@zip.com.au>
13893 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13894 sometimes needing writable input.
13896 2001-12-17 Jim Meyering <meyering@lucent.com>
13898 * doc/autoconf.texi (New Macros): Tweak wording.
13900 2001-12-14 Akim Demaille <akim@epita.fr>
13902 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13903 trailing files, don't apply `-rf' to files which might not be
13904 created by configure (core, core.*, and *.core), but just `rm -f'.
13905 Suggested by Jonathan Kamens.
13907 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13909 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13911 2001-12-14 Akim Demaille <akim@epita.fr>
13913 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13915 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13917 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13918 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13919 abs_srcdir, top_srcpath to abs_top_srcdir.
13920 (_AC_OUTPUT_FILES): Adjust.
13921 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13922 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13923 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13925 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13927 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13928 C/Fortran linking on HP/UX, by extracting the Fortran library
13929 search path from the LPATH line in the $F77 -v output.
13931 2001-12-12 Kevin Ryde <user42@zip.com.au>
13933 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13934 forbidden file descriptors table.
13936 2001-11-26 Akim Demaille <akim@epita.fr>
13938 * bin/autoscan.in (%c_keywords): Build it at top level.
13939 Map to 1 in order to simplify its uses.
13941 2001-11-26 Akim Demaille <akim@epita.fr>
13943 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13944 Remove $filepath, useless.
13945 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13946 variables, they are really part of the tokens.
13947 Split the input line on spaces and then look for tokens.
13948 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13949 because of `lex$U.$(OBJEXT)'.
13950 (&scan_files): Use "@list" instead of join.
13951 * doc/Makefile.am (CLEANFILES): Add *.fns.
13953 2001-11-26 Akim Demaille <akim@epita.fr>
13955 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13956 Remove, replaced by...
13957 * tests/wrappl.in: Be common for all the Perl executables.
13958 In particular autoscan and autoheader want -I.
13959 * configure.ac: Adjust.
13960 * lib/autoscan/headers: errno.h is portable.
13962 2001-11-26 Akim Demaille <akim@epita.fr>
13964 * bin/autoscan.in (used): New.
13967 2001-11-26 Akim Demaille <akim@epita.fr>
13969 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13971 (&scan_sh_file): Remove a duplicate pattern.
13972 (&check_configure_ac): Use long options.
13973 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13975 2001-11-26 Akim Demaille <akim@epita.fr>
13977 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13978 Before, having a line containing the opening of a multi line
13979 comment made the whole line be ignored.
13981 2001-11-26 Akim Demaille <akim@epita.fr>
13983 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13984 (testsuite Scripts): Be one of its subsection.
13985 (Autotest Logs): New.
13987 2001-11-26 Akim Demaille <akim@epita.fr>
13989 Test groups are now run two directories deeper.
13991 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13992 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13994 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13995 top_srcdir, builddir and top_builddir.
13996 Use `at_*dir' relatively to the directory containing the
13997 suite, use `*dir' when relatively to the current group dir.
13999 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14001 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14002 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14003 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14006 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14008 * doc/autoconf.texi (Using System Type): Add an example of `case
14009 $host' usage so people quit using `case $target' everywhere.
14011 2001-11-22 Akim Demaille <akim@epita.fr>
14013 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14014 spotted by Jim Meyering.
14016 2001-11-16 Paul Eggert <eggert@twinsun.com>
14018 This patch implements a `long double' suggestion by Oliver Kiddle.
14020 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14021 static, to catch errors if the value isn't known at compile-time
14022 and the compiler supports dynamic arrays. Change its name from
14023 `_array_' to `test_array' to avoid potential name clashes.
14024 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14025 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14026 better than double. Catch a bug in GCC 2.95.2 x86.
14027 * doc/autoconf.texi (C Compiler): Document the above.
14030 2001-11-13 Akim Demaille <akim@epita.fr>
14032 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14034 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14036 2001-11-13 Akim Demaille <akim@epita.fr>
14038 * lib/autotest/general.m4 (AT_INIT): After having run the test
14039 group, go back to the initial directory, not to at_suite_dir.
14041 2001-11-13 Akim Demaille <akim@epita.fr>
14043 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14044 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14045 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14047 (AT_CHECK_CONFIGURE): Use absolute paths.
14048 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14049 The problem is still the old one: there is no means in M4 (that I
14050 know about) to create a defining macro, because there is no means
14051 to create `$1' etc., therefore, the defining macro ``swallows''
14052 all the arguments meant to the defined macro.
14054 2001-11-13 Akim Demaille <akim@epita.fr>
14056 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14057 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14059 * tests/aclocal.m4: Remove, as it is no longer used.
14061 2001-11-13 Akim Demaille <akim@epita.fr>
14063 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14064 variable names when referring to a single test group, or to
14065 `suite' when referring to the whole test suite.
14066 `at_last_test' is removed: m4 compute at_format itself.
14067 (at_stdout, at_stder1, at_stderr): New variables.
14068 (AT_CHECK): Use them.
14070 2001-11-13 Akim Demaille <akim@epita.fr>
14072 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14074 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14075 Do it as soon as a test fails, don't wait till the end of the test
14077 Don't remove $as_me.[0-9]*, since these files no longer exist.
14079 2001-11-13 Akim Demaille <akim@epita.fr>
14081 * tests/tools.at: Use absolute paths, since we are no longer run
14084 2001-11-13 Akim Demaille <akim@epita.fr>
14086 Now that tests are running in their own private dir, there is no
14087 need to list the files to remove at the end of tests groups.
14089 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14090 (AT_data_files, at_data_files): Remove.
14091 (AT_CLEANUP, AT_DATA): Simplify.
14093 Remove the group dir if !debug && !failed.
14094 * tests/atspecific.m4: Adjust.
14096 2001-11-13 Akim Demaille <akim@epita.fr>
14098 Start a new layout for Autotest: `testsuite' creates
14099 `testsuite.dir' in which the at-check-line etc. files are to be
14100 found, and `testsuite.dir/003' where the test group 3 is run.
14102 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14103 at_check_line_file, at_format, at_test_normalized, at_group_dir
14105 Create the directories.
14106 Use absolute paths for at- files.
14107 (AT_CHECK): Adjust.
14109 2001-11-11 Michael Matz <matz@kde.org>
14111 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14113 (m4_car): Properly quote arguments.
14115 2001-11-13 Akim Demaille <akim@epita.fr>
14117 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14118 with stricter rules on LIBOBJS.
14120 2001-11-12 Paul Eggert <eggert@twinsun.com>
14122 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14123 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14126 2001-11-12 Akim Demaille <akim@epita.fr>
14128 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14130 2001-11-12 Akim Demaille <akim@epita.fr>
14132 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14133 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14134 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14135 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14136 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14137 specify to what the macro should be defined (typically to 1).
14139 2001-11-12 Akim Demaille <akim@epita.fr>
14141 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14144 2001-11-12 Akim Demaille <akim@epita.fr>
14146 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14147 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14148 definition used by Automake where LEX is +/- "${missing} lex" and
14149 `missing' itself contains variables.
14151 2001-11-12 Akim Demaille <akim@epita.fr>
14153 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14154 Now that M4sh pushes BODY, the comments were output at the end of
14157 2001-11-08 Akim Demaille <akim@epita.fr>
14159 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14160 that we can trace macros from aclocal.m4.
14161 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14162 obsoleted, and redirect to the former anyway.
14163 Reported by Ralf Corsepius.
14165 2001-11-08 Akim Demaille <akim@epita.fr>
14167 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14168 processed only if present.
14169 * tests/torture.at (Configuring subdirectories): Use autoreconf
14170 instead of successive calls to autoconf.
14171 Add a nonexistent subdirectory to exercise the patch above.
14172 Reported by Ralf Corsepius.
14174 2001-11-08 Kevin Ryde <user42@zip.com.au>
14176 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14177 doesn't accept .S files.
14179 2001-11-07 Akim Demaille <akim@epita.fr>
14181 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14182 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14183 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14184 * bin/autom4te.in (warn_forbidden): New.
14185 (handle_output): Use it.
14186 Read m4_pattern_forbid with messages.
14188 2001-11-05 Akim Demaille <akim@epita.fr>
14190 * bin/autom4te.in (--normalize): Remove.
14191 * lib/autom4te.in: Adjust.
14193 2001-11-05 Akim Demaille <akim@epita.fr>
14195 * tests/Makefile.am (testsuite): Rename this target as...
14196 ($(TESTSUITE)): this.
14199 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14201 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14202 the --prefix option, also remove it's argument.
14204 2001-11-05 Akim Demaille <akim@epita.fr>
14206 * doc/autoconf.texi (testsuite Invocation): Update.
14207 (Writing testsuite.at): Update.
14209 2001-11-03 Akim Demaille <akim@epita.fr>
14211 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14213 2001-11-03 Akim Demaille <akim@epita.fr>
14215 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14216 (&file_name_is_absolute): New, wrappers around routines from
14218 Use and export them.
14219 (&find_configure_ac): Optionally take a directory where to look at.
14220 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14222 Default @ARGV to `.', not find_configure_ac.
14223 (&autoreconf): Argument is a directory.
14224 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14225 * doc/autoconf.texi (autoreconf Invocation): Update.
14227 2001-11-03 Akim Demaille <akim@epita.fr>
14229 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14230 (@export_forward_subs): New.
14231 Add basename, dirname, and fileparse.
14233 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14234 Don't look for aclocal flags if we already know aclocal is not
14236 Move aclocal.m4t only if it exists.
14237 Reported by Ezra Peisach.
14239 2001-11-03 Akim Demaille <akim@epita.fr>
14241 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14242 passed on command line, defaulting to ./configure.ac if present.
14243 (&maybe_autoreconf, File::Find): Remove, unused.
14244 (&autoreconf): If autoconf is not used, don't try to trace.
14246 2001-11-02 Akim Demaille <akim@epita.fr>
14248 * configure.ac: Bump to 2.52g.
14250 2001-11-02 Akim Demaille <akim@epita.fr>
14254 2001-11-02 Akim Demaille <akim@epita.fr>
14256 * config/config.guess, config/config.sub, doc/standards.texi:
14257 * config/lispdir.m4: Update from masters.
14258 * configure.ac: Bump to 2.52f.
14260 2001-11-02 Akim Demaille <akim@epita.fr>
14262 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14263 Don't run aclocal when aclocal.m4 is not from aclocal.
14265 Don't run libtoolize and gettextize if --install is not given.
14267 2001-11-01 Paul Eggert <eggert@twinsun.com>
14269 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14270 be invoked before _AS_LINENO_PREPARE.
14271 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14272 than character ranges.
14274 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14275 invoking AS_BASENAME. Set the locale variables to 'C' if
14276 possible, as POSIX requires this to get the traditional
14278 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14280 2001-10-31 Paul Eggert <eggert@twinsun.com>
14282 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14283 with {}, as that triggers a bug in Bash 2.05.
14285 (_AS_LINENO_PREPARE): Use Sed rather than
14286 Awk. Fix the sed prepass to work even if there are multiple
14287 instances of $LINENO on the same line. Do not substitute for
14288 other variables like $LINENOT. Do not check file dates; such a
14289 check is unreliable on sufficiently fast machines, and removing
14290 the check makes the code simpler and more reliable. Check for
14291 output and chmod failures.
14293 * doc/autoconf.texi (Special Shell Variables): Document
14296 2001-10-31 Akim Demaille <akim@epita.fr>
14298 * tests/Makefile.am (atconfig): Remove this target, Automake
14301 2001-10-31 Akim Demaille <akim@epita.fr>
14303 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14304 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14305 provided, while it is optional.
14306 * configure.ac: Adjust.
14308 2001-10-26 Paul Eggert <eggert@twinsun.com>
14310 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14311 lib/Autom4te/Struct.pm:
14312 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14315 * doc/autoconf.texi (Special Shell Variables): Document some
14316 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14318 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14319 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14320 eval $LINENO is not portable in practice.
14322 2001-10-24 Akim Demaille <akim@epita.fr>
14324 * lib/Autom4te/General.pm (backname): New.
14326 2001-10-24 Akim Demaille <akim@epita.fr>
14328 * m4/: Remove, merged into...
14331 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14333 * doc/autoconf.texi (Shellology): Mention the problems with bash
14334 2.05's use of ANSI quoting in its `set' builtin.
14336 2001-10-22 Paul Eggert <eggert@twinsun.com>
14338 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14339 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14340 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14341 POSIX decided to standardize on the int flavor of strerror_r.
14342 Always do char* test, as there's no reason not to.
14343 Assign to a char* var, to catch strerror_r that returns int*.
14345 * doc/autoconf.texi (Particular Functions):
14346 Document the above changes. Also, document the fact that
14347 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14349 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14351 2001-10-20 Akim Demaille <akim@epita.fr>
14353 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14354 the executable was missing from the log.
14356 2001-10-20 Akim Demaille <akim@epita.fr>
14358 * lib/Autom4te/General.pm (&update_file): If destination is

14838 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14839 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14840 be used instead of ':'.
14841 * lib/autotest/general.m4: Replace occurrences of ':' in
14842 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14844 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14846 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14847 arguments. Fixed a typo.
14849 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14851 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14852 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14854 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14856 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14863 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14865 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14866 already have $file). Set output files to binary mode (helps avoid
14867 CR issues on DOSish systems).
14869 2001-09-19 Akim Demaille <akim@epita.fr>
14871 * lib/autotest/general.m4: Englishoes.
14872 From Tim Van Holder and Alexey Mahotkin.
14874 2001-09-18 Paul Eggert <eggert@twinsun.com>
14876 * doc/autoconf.texi (Common Shell Constructs): New node,
14877 documenting AS_DIRNAME.
14878 (Limitations of Usual Tools): Refer to it when discussing dirname.
14879 Also, update discussion of POSIX standard to reflect latest draft.
14881 * lib/autoconf/c.m4:
14882 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14884 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14885 Do not pass a first argument with leading '-'
14886 to expr, by parenthesizing initial integers that might be negative.
14888 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14889 now merely checks whether it is an error to pass an argument
14892 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14893 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14894 whether it is a (compile-time) error to pass an argument to
14895 getpgrp. This simpler test supports the revised documentation,
14896 and is all that AC_FUNC_GETPGRP's users really need.
14898 2001-09-18 Akim Demaille <akim@epita.fr>
14900 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14910 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14912 Add test for AS_BASENAME.
14913 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14914 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14915 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14916 * tests/base.at: Fixed the expected responses. The old ones were
14918 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14919 the documentation claims it should (and how it behaved in 2.13).
14921 2001-09-18 Akim Demaille <akim@epita.fr>
14923 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14924 the AC_CONFIG_COMMANDS invocation.
14925 This also solves the name clash problems.
14926 Don't set the package's ID.
14927 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14928 No longer to be shipped.
14929 (version.in): Remove.
14930 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14931 * lib/autoconf/status.m4: Adjust.
14932 Use `m4_PACKAGE_STRING'.
14933 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14934 the only optional argument is the name of the test suite.
14935 Expect `package.m4' to define the package signature.
14936 * lib/autom4te.in (Autotest): Add `package.m4?'.
14937 * tests/Makefile.am (package.m4): New.
14938 * tests/suite.at: ifnames is a victim.
14940 2001-09-18 Akim Demaille <akim@epita.fr>
14942 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14943 AC_LIBSOURCE, AC_CONFIG_FILES.
14944 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14945 program version string doesn't match the package's.
14946 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14949 2001-09-17 Paul Eggert <eggert@twinsun.com>
14951 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14952 Allow expression to return any value that can fit into unsigned long
14953 (not int, as before). Check for output errors.

14957 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14958 Always include <stdio.h> and <stdlib.h>. Evaluate
14959 the expression in an extra function before these includes. Call
14960 fprintf "%d" only after ensuring the argument is of type 'int'.
14961 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14963 2001-09-17 Paul Eggert <eggert@twinsun.com>
14965 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14966 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14967 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14968 when they don't exist.
14970 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14971 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14974 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14975 version with the version used by fileutils 4.1, except use
14976 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14979 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14981 2001-09-13 Akim Demaille <akim@epita.fr>

15021 * lib/autotest/general.m4 (AT_INIT): Create and remove
15022 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15023 test suites can cohabit.
15025 2001-09-13 Akim Demaille <akim@epita.fr>
15027 * tests/mktests.sh: Don't output banners for empty test files.

15133 2001-09-05 Akim Demaille <akim@epita.fr>
15135 Be ready to handle filenames as stupid as `dnl.at', for if even
15136 the maintainer is dumb enough to do that...
15138 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15139 excellence in M4 quotation: consider `__file__' is active.
15141 And BTW, when invoking m4, pass the --include in the right order:

15299 2001-08-31 Akim Demaille <akim@epita.fr>
15301 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15302 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15304 Use -e, not -f, since /dev/null for instance is OK.
15305 (&parse_args): Adjust.
15306 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

15316 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

15323 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15324 indeed related to running the test suite, while passing

15326 Autoconf executables. So don't do that, leave it to...

15328 * tests/autoscan: New.
15329 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

15815 autom4te.cache (it's a directory, not a file.
15816 * Makefile.am: Ditto (but maintainer-clean-local).
15818 2001-08-15 Akim Demaille <akim@epita.fr>
15820 * bin/autom4te.in (@m4_warning): New.
15821 (&handle_m4): Use it.
15822 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15823 warnings are issued at each run.
15824 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15825 is in the src tree.

15894 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15895 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15896 * doc/autoconf.texi (C Compiler Characteristics): Update
15897 documentation for AC_C_BIGENDIAN.
15899 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15901 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15902 magic values from an object file when cross-compiling.
15903 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15905 2001-08-10 Akim Demaille <akim@epita.fr>
15907 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15909 Suggested by Russ Allbery.
15911 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15913 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15914 current $prefix to the sub-configures.
15916 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15918 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15919 extension (needed on BeOS). Reported by Guido van Rossum.
15921 2001-08-09 Akim Demaille <akim@epita.fr>
15923 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15925 2001-08-07 Akim Demaille <akim@epita.fr>
15927 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15929 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15930 No need to remove the files before and after the each test, before
15931 each test and at the end of the suite is enough.
15932 Display only the children `times', not the shell's.
15933 If the test failed or was skipped, at-times is not available.
15935 2001-08-07 Akim Demaille <akim@epita.fr>
15937 Always produce testsuite.log, including when there are no
15938 failures. This helps getting information on skipped tests, and
15939 duration of the tests. Err, implement the latter btw.
15941 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15942 Dump information on the first run of each test.
15943 (AT_CLEANUP): Create `at-times' containing the duration of the
15946 2001-08-07 Akim Demaille <akim@epita.fr>
15948 The use of `dumpstat' revealed that `len' was used although it
15949 should not. m4_text_wrap was using it, but in the Autoconf world
15950 where it is legal. Hence (i) test M4sh in its own world, not
15951 Autoconf's, and (ii), ahem, fix the bug :)
15953 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15954 does not like `' instead of [].
15955 (AT_INIT): Forbid `^_?AT_'.
15956 And don't output such tokens.
15957 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15958 `script.as', and `autom4te.cache'.
15959 Remove `empty' and `macro' which are no longer used.
15960 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15961 * tests/m4sugar.at: Use it.
15962 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15964 2001-08-07 Akim Demaille <akim@epita.fr>
15966 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15968 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15970 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15972 2001-08-04 Akim Demaille <akim@epita.fr>
15974 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15975 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15977 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15978 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15979 (AC_F77_MAIN): Likewise.
15981 2001-08-04 Akim Demaille <akim@epita.fr>
15983 Don't rely on M4sugar outputting the patterns in files, since we
15984 might process the output _without_ running m4, hence without these
15987 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15988 * bin/autom4te.in (@Request::includes): Remove, unused.
15989 (@Request::source): Rename as...
15990 (@Request::input): this.
15991 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15992 (&handle_output): Fetch the patterns from the traces.
15993 `$forbidden' and `$allowed' are constant: use m//o.
15994 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15995 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15997 2001-08-04 Akim Demaille <akim@epita.fr>
15999 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
16000 autoconf', i.e., in addition to caching traces, cache the output.
16002 * bin/autom4te.in (Request::cache): Rename as...
16003 (Request::id): this.
16004 ($cache, $icache, $tcache, $ocache): New.
16005 (&handle_m4): Save M4 output in the cache instead of $tmp.
16006 (&handle_output): Adjust.
16007 (&up_to_date_p): Check that the output cache is up to date too.
16008 (top level): Run `&handle_m4' iff force or the cache is invalid.
16009 Run `&handle_output' if the output cache is more recent.
16011 2001-08-04 Akim Demaille <akim@epita.fr>
16013 * bin/autom4te.in ($force): New.
16014 (&parse_args, &print_usage): -f, --force is a new option.
16015 (&handle_output): CPP directives might have spaces after `#'.
16016 (&parse_args): The first file only can be frozen.
16018 2001-08-04 Akim Demaille <akim@epita.fr>
16020 Don't let autom4te compute the `include' traces several times:
16021 first check that the trace cache file is up to date, and then
16022 compare its timestamp with that of the output.
16024 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16025 the preamble. Don't require 5.005 as Autom4te::General does it,
16026 and better yet (use `use', not `require'!).
16027 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16028 Class::Struct as Autom4te::Struct.
16029 * lib/Autom4te/General.pm (File::stat): Use it.
16030 (&mtime): New, export it.
16031 * bin/autom4te.in: Use it.
16032 Declare `$req' is invalid if it is outdated.
16033 Don't declare it valid before saving it if something went wrong.
16035 2001-08-04 Akim Demaille <akim@epita.fr>
16037 Autom4te shall not encode Autoconf data, and preselecting traces
16038 must be proposed to the users.
16040 * bin/autom4te.in (@required_trace): Remove.
16042 (&parse_args, &print_usage): -p, --preselect is a new option.
16043 (&up_to_date_p): Adjust.
16044 * bin/autoconf.in: Preselect some Autoconf macros.
16046 2001-08-04 Akim Demaille <akim@epita.fr>
16048 * tests/tools.at (autoconf --trace: user macros): Check traces on
16049 macros invoked without arguments, and macros invoked with multiple
16052 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

16057 2001-08-03 Akim Demaille <akim@epita.fr>
16059 * bin/autoconf.in ($@): Work around the usual sh bug.
16062 2001-08-03 Akim Demaille <akim@epita.fr>
16064 Clean up the handling of the M4 builtins tracing exception.
16066 * bin/autom4te.in (Request::request): Don't complete M4 builtins
16068 (@m4_builtins): Rename as...
16069 (@m4_builtin): this.
16070 (%m4_builtin_alternate_name): New.
16071 (&parse_args): Complete the trace requests with alternate names.
16072 (&handle_traces): Hence no longer do it here.
16073 (&trace_requests): Remove, unused.
16075 2001-08-03 Akim Demaille <akim@epita.fr>
16077 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
16078 m4_if, and m4_wrap.
16080 2001-08-03 Akim Demaille <akim@epita.fr>
16082 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
16083 (m4_divert_pop): Dump the whole diversion stack when a diversion
16085 * bin/autom4te.in (&handle_output): Remember of the first
16086 occurrence of a possibly undefined macro, not the last.
16087 Complain about the possibly undefined macros in the same order as
16088 the appear in the output.
16089 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16090 * tests/tools.at (autoconf: forbidden tokens, basic)
16091 (autoconf: forbidden tokens, exceptions): No longer sort
16092 autoconf's stderr, as it is now deterministic.
16093 Check that `dnl' is caught.
16095 2001-08-01 Akim Demaille <akim@epita.fr>
16097 * configure.ac: Bump to 2.52c.

16114 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
16115 `END', as `Autom4te::General::END' will be triggered.
16116 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
16117 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
16118 system to run `mv', `rm', and `cmp'.

16122 * lib/Autom4te/General.pm (&unique): New.
