1690 Cover more potentially problemtic file names. Use the new
1693 Properly handle funny file names for headers in config.status.
1694 The test suite did not cover this bug because the code was not
1695 quoting properly the arguments of `rm -f' (which "fails" silently)
1696 as well as the arguments of `diff' (whose output was redirected to
1697 /dev/null so we couldn't see its error message).

1815 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1817 <DEFAULTS>: Delay computation of variables based on $at_dir...
1818 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1819 <TESTS>: Re-invoke via absolute name, since -C may be in effect.

1837 * doc/autoconf.texi (Particular Programs): Do not mention the
1838 Autoconf version in which the AC_PROG_INSTALL change was done.

1843 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1844 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1845 mode, we change to the source directory, also set $ac_pwd so we
1846 do not go back to the build tree for the next config subdir.
1847 * tests/torture.at (Deep Package): Extend test to contain two
1848 config subdirs on the top level.
1850 Fix parallel `maintainer-check'.
1851 * Makefile.am (maintainer-check-tests): Depend on `all'.
1852 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

1879 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1881 * tests/Makefile.am (noinst_SCRIPTS): Renamed from

1902 (m4_require): Use m4_do, not m4_join.
1904 Fix some whitespace tests on cygwin.

1930 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1931 (Substitute a newline, datarootdir workaround): Likewise.
1932 (Define a newline): Adjust for linenumber changes in configure.ac.
1933 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1942 * tests/m4sh.at (LINENO): Quote $0.
1944 Fix testsuite program wrapper for whitespace in `pwd`.
1945 The problem here is that the usual mantra is that command
1946 variables can contain arguments, thus we cannot just escape
1947 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1948 $top_builddir/tests directory early in $PATH, so that the
1949 wrappers are found by their plain name.
1950 * tests/wrapper.as: Put $testdir early in $PATH.

1963 <at_func_create_debugging_script, Driver Loop>:
1964 Quote $at_group_dir.
1965 * tests/autotest.at (whitespace in absolute testdir): New test.
1967 * lib/autom4te.in: Quote @datadir@.
1969 Proper file name escaping in Autoconf programs and Perl modules.
1970 This includes escaping of characters special to the shell
1971 as well as special to Perl, e.g., leading `<' or `>'.
1972 For example, when $file starts with `>', `open ">$file"'
1973 wrongly tries to append to a different file.
1974 * bin/autoconf.as: Fix quoting for autom4te options.
1975 * lib/Autom4te/General.pm (shell_quote): New function, taken
1976 from coreutils, written by Jim Meyering.

1980 * bin/autoreconf.in (parse_args): Likewise.

1984 * bin/ifnames.in: Likewise, XFile usage fixes.
1985 * tests/tools.at (autom4te and whitespace in file names): Extend
1986 test. Test twice, with special characters allowed on w32, and the
1987 rest. Test leading and trailing whitespace, for `open_quote'.
1988 (autotools and whitespace in file names): New, analogous test.

1990 by Russ Allbery and Eric Blake.

1996 (update_file, contents): Use it.
1998 * Makefile.am (autom4te-update): Rewrite for git.
2000 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2002 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
2004 Fix copyright years.
2005 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
2006 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

2018 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2020 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2021 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2022 #undef as this runs afoul of our new way of creating config.h.
2023 Problem reported by Jim Meyering in
2024 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2026 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2028 Fix autom4te for unusual characters in input file names.
2029 * bin/autom4te.in (files_to_options): Quote active characters
2031 * tests/tools.at (autom4te and white space in file names):
2034 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2035 Document that Tru64 awk always splits $0.
2037 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2039 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2040 `#AT_STOP_...' line at the end of each test.
2042 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2044 * lib/autotest/general.m4 (AT_INIT): For awk line number
2045 extraction script, ensure `$at_group' has a defined value
2046 even for the empty set, and properly quote its usage inside
2049 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2051 * doc/autoconf.texi (Shell Functions): New chapter. Document
2052 IRIX sh $0 issue in functions, move content from ...
2053 (Portable Shell): ... here.
2054 (Shell Script Compiler): Note that shell functions are not
2055 totally unportable any more.
2057 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2058 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2060 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2061 extracting the line numbers of the last needed test.
2063 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2065 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2068 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2070 Fix IRIX testsuite debugging failures: $0 in functions.
2071 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2072 Do not use $0 inside a function, as IRIX sh will set that to the
2073 function name rather than the script invocation name.
2075 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2076 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2078 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2079 to extract test scripts.
2080 (AT_INIT): Extract and cache test script line numbers.
2082 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2084 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2085 subsequent fixups; the awk -> here-document conversion trashes
2086 performance too much with AIX sh.
2088 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2090 * tests/local.at: Do not test m4, perl with AT_TESTED.
2092 Diagnose and guard against write errors dealing with config.status.
2093 The general idea is this: all write failures from `configure'
2094 writing `config.status' are indicated by $ac_write_error, which
2095 is only checked at the end. This is safe because config.status
2096 code is not executed before the file is complete. Other write
2097 failures, be they inside config.status, or in sub shell/awk
2098 scripts spawned from configure or config.status, typically need
2099 earlier checking, as their results are used right afterwards.
2100 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2101 before writing config.status, check afterwards.
2102 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2103 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2104 Set `ac_write_error' for write failures to config.status. Barf
2105 upon write failures to temporary files.
2106 Adjust note about closing and reopening the here-document.
2107 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2108 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2109 reopening the here-document.
2110 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2111 Ensure `ac_write_error' does not escape into config.status.
2112 Also, add a couple of code paths not yet exercised in the test
2113 suite: a config file with input from stdin, and a config header
2115 Suggestion for catching write errors by Bruno Haible.
2117 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2119 Avoid error with Tru64 awk and testsuite lines with many words.
2120 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2121 reads the testsuite, set the field separator to an unusual value,
2122 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2123 even splits the input if $i, i>0, was never accessed in the script.
2125 Revert 2007-10-17 change.
2126 * TODO: Multiline args in config files and headers mean something
2127 different and are not fixed, see
2128 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2129 Report by Stepan Kasal.
2131 * doc/autoconf.texi (Generic Programs): Fix typo.
2133 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2135 AC_*_TOOL does not canonicalize the prefix
2136 * doc/autoconf.texi (Generic Programs): Do not say that
2137 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2139 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2141 Diagnose write errors in config.status instantiations.
2142 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2143 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2145 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2146 Extend test to also check for some write error failures, using...
2147 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2148 Report by Bruno Haible.
2151 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2153 (_AT_CHECK): Use less indentation, to save space.
2155 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2157 Add witness macro for @top_build_prefix@ substitution.
2158 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2159 (_AC_OUTPUT_FILE): Mention it here.
2161 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2162 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2164 * lib/autotest/general.m4 (at_func_test): Remove.
2165 (AT_INIT): Pre-extract test groups into separate files.
2166 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2167 Remove at-test-source files together with the $at_group_dir.
2168 * tests/autotest.at (Long test source lines): New test.
2170 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2172 Shell functions and variables may share a namespace.
2173 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2176 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2178 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2181 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2183 * lib/autoconf/status.m4: Fix a couple of comment typos.
2185 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2187 2007-11-13 Jim Meyering <meyering@redhat.com>
2189 Clean up the rule to create "expr".
2190 * tests/Makefile.am (expr): Don't redirect directly to target.
2191 Redirect just once, not for each echo statement.
2192 Use $@, not literal "expr".
2194 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2196 Don't worry about preprocessor when testing long long.
2197 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2198 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2199 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2200 These no longer check for preprocessor flaws.
2201 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2202 Do not check for preprocessor flaws.
2204 2007-11-13 Jim Meyering <meyering@redhat.com>
2206 Adapt dependencies, now that a version change doesn't modify configure.ac
2207 * GNUmakefile: Remove "make clean" kludge.
2208 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2210 Don't redirect directly to target.
2211 Use $@, not literal "version.m4".
2213 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2215 * doc/autoconf.texi (Making testsuite Scripts): Document
2216 ":;{" shorthand as in previous patch.
2218 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2220 * doc/autoconf.texi (Limitations of Builtins): Document problem
2221 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2223 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2224 Use ":;{" shorthand.
2225 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2227 2007-11-12 Jim Meyering <meyering@redhat.com>
2229 Add more non-srcdir build support.
2230 * GNUmakefile (dummy): Split a long line.
2231 Add -v option to autoreconf invocation.
2233 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2234 * GNUmakefile (dummy): Remove INSTALL.
2236 Remove racy commands to build scripts in bin/ and tests/.
2237 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2238 are guaranteed to be built, remove the rules that tried to build
2239 them. Before, with a parallel build, these rules could lead to
2240 two processes writing tests/wrapper.in concurrently.
2242 Build in man/ only *after* building in bin/ and tests/.
2243 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2244 in both bin/ and tests/.
2246 Accommodate non-srcdir build-from-checkout.
2247 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2248 Use git's --git-dir=$srcdir/.git option.
2249 Add quotes, in case tarball_version_file contains shell meta-characters.
2250 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2251 * configure.ac: Pass "." to git-version-gen.
2253 Avoid spurious test failures due to version skew.
2254 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2256 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2258 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2259 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2260 Remove conftest.dSYM directory.
2261 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2262 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2263 Remove `conftest.*' recursively.
2264 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2265 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2267 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2269 Report and analysis by Jeff Squyres and Peter O'Gorman.
2271 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2273 Fix typos in variable names.
2274 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2276 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2278 Document that $((expression)) is not portable.
2279 * doc/autoconf.texi (Shell Substitutions): Here.
2281 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2283 Ignore configure --help* errors due to LINENO-impaired shells.
2284 * tests/torture.at (Configuring subdirectories, Deep Package):
2285 In the --help* tests in read-only trees, make `.' temporarily
2286 writable again for the `stderr' file, and ignore errors due to
2287 the attempt to write configure.lineno.
2288 Report by Patrick Welche.
2290 2007-11-10 Jim Meyering <meyering@redhat.com>
2292 Generate package.m4 in build-dir, not srcdir.
2293 * tests/Makefile.am (package.m4): Adjust target.
2294 Don't redirect directly to $@.
2295 (CLEANFILES): Add package.m4.
2296 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2298 When running $(AUTOTEST), search "." before searching $(srcdir).
2300 Avoid a race condition that would make parallel "distclean" fail.
2301 * tests/Makefile.am (distclean-generic): Replace the default,
2302 automake-provided rule with an identical one, but with an additional
2303 dependency on distclean-local. Simply adding the dependency would
2304 cause automake not to emit the rule at all.
2305 * BUGS: Building with -jN works, now.
2307 Distribute git-version-gen.
2308 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2309 since GNUmakefile is distributed, and requires it for dist* rules.
2311 Remove two more generated files from version control.
2312 * INSTALL: Remove generated file.
2313 * lib/autoscan/autoscan.list: Remove generated file.
2315 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2317 * GNUmakefile (PATH): Remove stray apostrophes; they become
2318 part of PATH, which isn't wanted here.
2320 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2322 New config files output variable `top_build_prefix'.
2323 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2325 * doc/autoconf.texi (Preset Output Variables): Document it.
2327 Report by Bob Friesenhahn.
2329 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2330 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2331 function, to parametrize arithmetic with expr vs. the shell.
2332 Use it where possible.
2333 Suggestion by Benoit Sigoure.
2335 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2337 Adjust the documentation of autotest WRT atlocal.
2338 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2339 when using Automake, to write a rule to produce atlocal, since it's
2340 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2341 distributed, not atconfig.in.
2343 2007-11-04 Eric Blake <ebb9@byu.net>
2345 Update list information.
2346 * README: Mention new autoconf-commit list.
2347 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2349 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2351 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2353 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2355 * build-aux/.gitignore: Ignore mkinstalldirs.
2357 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2359 2007-11-03 Jim Meyering <meyering@redhat.com>
2361 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2362 * build-aux/git-version-gen: This syncs from coreutils.
2364 Adjust the build procedure so "make check" works reliably.
2365 * README-hacking: Include an extra step between "make" and
2366 "make check" to ensure that the latter passes.
2368 Use just-built tools, when possible.
2369 * GNUmakefile (PATH): Set and export here, ...
2370 (dummy): ... rather than here.
2372 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2373 and Andreas Schwab <schwab@suse.de>
2375 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2378 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2380 * configure.ac (AC_PREREQ): Require version 2.60, for
2381 AC_PROG_SED, AC_PROG_GREP.
2383 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2384 and Jim Meyering <meyering@redhat.com>
2385 and Andreas Schwab <schwab@suse.de>
2386 and Eric Blake <ebb9@byu.net>
2388 Document a bug in GNU Bash with compound commands and redirections.
2389 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2390 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2393 2007-11-03 Eric Blake <ebb9@byu.net>
2395 Support m4 1.4.5 in testsuite.
2396 * tests/torture.at (Define a newline): Exclude line numbers in
2398 Reported by Ralf Wildenhues.
2400 2007-11-03 Jim Meyering <meyering@redhat.com>
2402 Remove automake-provided files from version control.
2403 * build-aux/elisp-comp: Remove file.
2404 * build-aux/install-sh: Remove file.
2405 * build-aux/missing: Remove file.
2406 * build-aux/mdate-sh: Remove file.
2407 * build-aux/.gitignore: New file.
2408 Suggestion from Ralf Wildenhues.
2410 2007-11-03 Eric Blake <ebb9@byu.net>
2412 Adjust version comparison to account for git snapshot numbers.
2413 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2414 component separator.
2415 * doc/autoconf.texi (Number processing Macros)
2416 <m4_version_compare>: Document this change.
2417 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2419 2007-10-30 Bruno Haible <bruno@clisp.org>
2421 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2422 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2423 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2424 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2425 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2426 Suggested by Paul Eggert.
2428 2007-10-28 Jim Meyering <meyering@redhat.com>
2430 * README-hacking: Autoconf, Automake, and Perl are required to build.
2431 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2433 2007-10-28 Jim Meyering <meyering@redhat.com>
2435 README-hacking: Recommend running autoreconf -vi.
2436 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2437 so that we use just-built tools when they're available.
2438 Suggestions from Ralf Wildenhues.
2440 2007-10-28 Jim Meyering <meyering@redhat.com>
2442 Make inter-release --version output more useful.
2444 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2445 which indicates that it is built using the 19th change set
2446 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2447 is a prefix of the commit SHA1.
2448 * build-aux/git-version-gen: New file.
2449 * configure.ac: Run it to set the version.
2450 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2451 * Makefile.am (dist-hook): Arrange so that .version appears only
2452 in distribution tarballs, never in a checked-out repository.
2453 * .gitignore: Add .version here, too. Just in case.
2454 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2455 not configure.ac, now that the version number changes automatically.
2457 Ensure that $(VERSION) is up to date for dist-related targets.
2458 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2459 git-version-gen doesn't match $(VERSION), but only for dist targets.
2461 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2463 Fix `Deep Package' failure with a configure script early in PATH
2464 * tests/torture.at (Deep Package): Add `.' early in PATH.
2465 Report by Jim Meyering.
2467 2007-10-27 Jim Meyering <meyering@redhat.com>
2469 Remove all generated files from version control.
2470 * aclocal.m4: Remove.
2471 * configure: Remove.
2472 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
2473 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
2474 * README-hacking: New file: how to build from just-checked-out sources.
2476 2007-10-23 Eric Blake <ebb9@byu.net>
2478 Improve corner case of m4_expand.
2479 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
2481 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
2482 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
2485 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
2487 * doc/make-stds.texi: Update from gnulib.
2489 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2490 and Eric Blake <ebb9@byu.net>
2492 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
2493 problem reported by Bruno Haible in
2494 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
2496 2007-10-22 Eric Blake <ebb9@byu.net>
2498 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2501 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2503 Don't check for bug in HP-UX 11.00 cpp.
2504 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2505 Use -1ull rather than -1u, since that causes problems with gnulib; see
2506 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
2508 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2510 * tests/autotest.at (Backquote command substitution)
2511 (Multiline backquote command substitution)
2512 (Parenthetical command substitution)
2513 (Multiline parenthetical command substitution): Fix typos in
2516 2007-10-21 Eric Blake <ebb9@byu.net>
2518 * configure: Regenerate.

3730 AC_CHECK_TYPE, AC_CHECK_TYPES.
3731 * doc/autoconf.texi (Generic types): C types must be type-names

3733 must not be anonymous.

3735 for C++; this drops support for anonymous struct and union types,
3736 which were problematic anyway.

3756 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3757 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3758 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3759 works but the latter doesn't, then it's a valid type.
3760 This lets people use function types and so forth.
3761 For C++ there doesn't seem to be a simple solution, so leave it alone.
3762 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3763 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3764 AC_CHECK_TYPE; that wasn't documented or necessary.

3821 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3822 (Limitations of Usual Tools): Also list \< and \>, and mention that

3825 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3827 * doc/autoconf.texi (Specifying Names): `--host' does not
3828 change the build type.

4002 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4004 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4005 feedback. The most important changes document what happens when
4006 you convert an out-of-range value to a signed integer type, and
4007 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4010 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4011 rewrite, taking notions from the recent discussion on the gcc and
4012 autoconf mailing lists; please see
4013 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4014 and follow the many links.
4015 (Integer Overflow Basics, Signed Overflow Examples):
4016 (Optimization and Wraparound, Signed Overflow Advice):
4017 (Signed Integer Division): New sections.
4019 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4021 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4022 preprocessor macro arguments in traced name.
4023 * doc/autoconf.texi (Defining symbols): Document longstanding
4024 support for AC_DEFINE-ing macros with arguments, and document
4025 behavior when the same variable has multiple AC_DEFINEs.
4026 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4027 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4028 macros directly, giving much shorter and simpler code.
4030 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4032 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4033 space before "$ac_configure_args" to prevent a 'config.status
4034 --recheck' failure if ac_configure_args doesn't contain a leading
4035 space. This works around a problem with the XEmacs configure.ac,
4036 which uses the (undocumented) ac_configure_args variable
4037 inconsistently with Autoconf.
4039 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4041 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4042 Include <limits.h>, and use its INT_MAX to rewrite the
4043 j loop so that it does not overflow 'int'. Problem reported by
4045 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4046 Play it safe by shifting left by 1 rather than multiplying by 2,
4047 as GCC is less likely to optimize this away when the value
4048 is signed (when it assumes overflow leads to undefined behavior).
4049 Also, don't assume time_t uses two's complement.
4051 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4053 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4054 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4055 dumps core on it. Report by Tim Rice.
4057 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4059 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4060 --disable-option-checking to --help output even when
4061 AC_PRESERVE_HELP_ORDER is not used.
4062 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4063 --with argument, rather than argument with [-.] replaced by
4065 * NEWS: Fix typo in previous change; the news was in the
4068 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4070 * NEWS: Warnings are now generated by default for unknown
4071 --enable-* and --with-* options.
4072 * doc/autoconf.texi (Option Checking): Renamed from
4073 (Configure Option Checking). Tighten up the wording a bit.
4074 (External Software, Package Options): Cross-reference to Option
4075 Checking, and use this to shorten our section.
4076 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4077 "$x" to test "x$foo" != x.
4078 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4079 Don't warn if $enable_option_checking is "no".
4080 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4081 ac_unrecognized_opts to the empty string.
4082 Don't echo the unrecognized opts, as this might mishandle
4083 backslashes or leading -.
4084 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4085 usage next to the other --disable-FEATURE options in the
4088 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4090 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4091 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4092 Print warning for unrecognized --with and --enable options
4093 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4094 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4095 Disable option checking when subdirs are configured.
4096 (AC_OUTPUT): If warnings are enabled, print warning about
4097 unrecognized --with and --enable options at the end of
4098 the configure output (as well as at the beginning).
4099 * doc/autoconf.texi (Option Checking): New node.
4100 Document new option warning functionality.
4102 2006-12-16 Eric Blake <ebb9@byu.net>
4104 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4105 * NEWS: Start news for current version.
4107 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4109 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4110 Define HAVE_GETMNTENT to 1, not to the empty string.
4111 Problem originally reported by Jochen Friedrich in
4112 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4114 This change prompted by a problem report by Andrey Simonenko in
4115 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4116 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4117 object-like macros only, in the traditional portable character
4119 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4120 Warn about attempts to define things that are not identifiers.
4121 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4122 awful hack that AC_DEFINEd macro names containing parentheses.
4124 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4126 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4127 too drastic, even if Texinfo in theory requires it for info mode.
4129 (config.status Invocation): Renamed back from Recreating a
4131 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4132 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4134 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4136 * NEWS: Version 2.61a.
4138 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4139 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4141 * NEWS: Document changes with echo and printf, and the lack
4142 of limits on the total size of multi-line values of substituted
4143 variables, and the AC_FUNC_FSEEKO fix.
4145 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4147 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4148 Writing configure.ac.
4149 (Autoconf Input Layout): Renamed from configure.ac Layout.
4150 (Recreating a Configuration): Renamed from config.status Invocation.
4151 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4152 (acconfig Header): Renamed from acconfig.h.
4153 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4154 (Writing Testsuites): Renamed from Writing testsuite.at.
4155 (Autom4te Cache): Renamed from autom4te.cache.
4157 * BUGS: Remove mention of VPATH problem, since it's now documented
4158 not to be a bug in the Autoconf build procedure itself, but rather
4159 a problem with the proprietary `make' programs.
4161 * doc/autoconf.texi (Build Directories): Add a cross reference
4164 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4165 * doc/standards.texi: Sync from gnulib.
4167 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4168 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4169 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4170 generated automatically.
4172 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4174 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4175 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4176 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4178 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4180 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4181 `CEOF$ac_eof' special marker, the awk script cannot contain a
4182 line matching `^CEOF', so this is not needed any more.
4183 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4184 special marker in the test.
4186 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4188 * tests/tools.at (autom4te preselections): Use `find -newer';
4189 remove one of the sleeps.
4191 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4192 more readable, using ...
4193 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4195 * doc/autoconf.texi (autoheader Invocation): Do not double-
4196 quote the parameter of `AH_BOTTOM' in the example.
4198 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4200 * doc/autoconf.texi (Configuration Headers): Remove the
4201 example with multiple input files.
4202 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4203 multiple input files.
4205 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4207 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4208 creating the awk substitution script, handle one input line at a
4209 time, so that the maximum length of a substituted (multi-line)
4210 value is not limited by the size of the sed pattern space.
4211 The trade-off is a slightly repetitive sed script.
4212 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4213 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4214 * tests/torture.at (Substitute a 2000-byte string): Increase the
4215 test with several long lines, they should not be caught by sed
4218 * tests/tools.at (autom4te preselections): New test, to flag
4219 entries missing from autom4te.cfg.
4220 Report by David Byron <dbyron@hheld.com>.
4222 * tests/torture.at (Substitute a 2000-byte string): Actually use
4223 AC_PROG_AWK, so the last change works as intended.
4224 (Substitute and define special characters): Likewise.
4225 (Substitute a newline): Likewise.
4227 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4228 instead of `awk' consistently.
4229 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4230 * tests/torture.at (Torturing config.status): Test both the
4231 result of AC_PROG_AWK and plain awk.
4232 (Substitute a 2000-byte string): Likewise.
4233 (Substitute and define special characters): Likewise.
4234 (Substitute a newline): Likewise.
4236 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4238 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4239 can be assigned to a function pointer. Problem reported by
4240 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4241 part of a patch by Ralf Wildenhues in that same bug report.
4243 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4245 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4246 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4248 2006-12-01 Eric Blake <ebb9@byu.net>
4250 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4251 cross-compiling from cygwin to mingw.
4252 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4253 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4254 to lib/autoconf/c.m4.
4256 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4258 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4259 string for more reliable failure. Wrap the entire test that
4260 causes the broken Solaris printf to dump core, in a subshell,
4261 so the segmentation fault message is reliably suppressed.
4262 Fix shell expansion errors by using /usr/ucb/echo always;
4263 avoid an error on systems without it by another subshell.
4264 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4265 subshell-$as_echo to `as_echo', for better error message.
4267 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4269 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4270 `BASH_SOURCE' contain a newline, set them to empty, as they may
4273 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4275 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4276 years and is too hard to maintain now. The last straw was
4277 reported by Jerker Baeck in
4278 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4279 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4280 * doc/autoconf.texi (Particular Functions): Move
4281 AC_FUNC_SETVBUF_REVERSED from here...
4282 (Obsolete Macros): ... to here. Say that it does nothing now.
4283 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4284 Turn into (almost) a no-op.
4286 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4288 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4289 These macros are obsolescent and new applications shouldn't need them.
4290 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4291 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4292 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):

4297 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4299 * doc/autoconf.texi (Setting Output Variables): Mention that
4300 @VAR1@VAR2 has unspecified behavior. Problem reported by
4302 * NEWS: Mention this.
4304 * Makefile.am: Put only a single '#' into the copyright notice,
4305 so that it's also present in the output file. Standardize wording
4306 in makefile copyright notices to match GNU coding standards.
4307 * bin/Makefile.am: Likewise.

4320 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4322 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4323 in the sed script that mangles the awk script: delete up to the
4324 first exclamation mark only.
4325 * tests/torture.at (Substitute and define special characters):
4328 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4330 Rewrite config files generation: avoid quadratic growth in
4331 the number of substituted variables by using awk instead of sed
4332 for the bulk of the substitutions.
4333 * NEWS: Mention this.
4334 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4335 forbidden in the output (and thus input) file.
4336 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4337 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4338 generate just one large awk script for substitutions,
4339 eliminating much of the earlier complexity, while adding some
4340 new complexity. Only expand the substitution templates at
4341 configure time, for smaller configure script size. If
4342 _AC_SUBST_FILES are used, test 'awk' for working getline support
4343 at config.status time. If absent, interpolate through the
4344 shell. The awk script was written with much help
4345 from Paolo Bonzini and Paul Eggert.
4346 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4347 (_AC_SED_FRAG_NUM): Likewise.
4348 (_AC_SUBST_CMDS): Renamed from...
4349 (_AC_SED_CMDS): ...this.
4350 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4351 * tests/torture.at (Substitute a 2000-byte string): Also
4352 substitute a line with 1000 words, and a variable with several
4354 (Substitute and define special characters): Test awk special
4355 characters, and put substitution input strings `@foo@' in the
4356 output, to test that no recursion happens; test several other
4357 combinations from Paolo Bonzini.
4359 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4361 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4362 that replaced echo with AS_ECHO where this wasn't necessary.
4363 Problem reportd by Ralf Wildenhues.
4364 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4365 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4366 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4368 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4370 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4372 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4374 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4375 that traditional Awk lacks 3-arg "split". It has it.
4376 Mention that FS must be a single character, and a few other
4377 99-byte limits of traditional Awk.
4378 Mention that if (i in a) doesn't work with traditional Awk.
4380 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4382 * tests/autotest.at (BSx641-newline in command):
4383 (BS-BS-newline in command, BSx640-newline in command):
4384 (Newline-CODE-BS-newline in command):
4385 (Single-quote-BS-newline in command):
4386 (Single-quote-newline-BS-newline in command):
4387 Use printf '%s\n' instead of echo, for portability to hosts
4388 where echo interprets backslashes. This will break on hosts
4389 that lack printf, but for now let's assume all such hosts
4390 are dead (if not, we should get reports of test failures).
4392 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4394 'echo' has some portability problems, when given a first argument
4395 with a leading '-', or when given any argument containing '\'.
4396 Avoid using 'echo' in these cases.

4400 * lib/autotest/general.m4 (AT_INIT): Likewise.
4401 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the

4425 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4426 Don't use ECHO_T, since ECHO_N is now reliable.
4427 * lib/autotest/general.m4 (AT_INIT): Likewise.
4428 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4429 rather than using a here-document to put the script into a file.

4433 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4434 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4435 bug, but we might as well stop using ECHO_N and ECHO_C internally.

4440 operand, as AS_ECHO requires. Avoid double file name expansion.
4441 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4442 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

4444 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.

4446 Double-quote strings that would otherwise contain M4 comments.
4447 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4449 * configure.ac (AC_INIT): Bump to 2.61a.
4452 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4456 * configure.ac (AC_INIT): Bump to 2.61.
4459 * tests/autotest.at (Macro with backslash in a test title):
4460 Comment out for now, as this tests neither fails nor passes
4461 reliably. Problem reported by Ralf Wildenhues.
4463 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4465 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

4540 benefit of platforms like Solaris+GCC where it is common to have a
4541 non-working g++ installation.

4548 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4551 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4553 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4554 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4555 Imported from a similar patch to gnulib by Bruno Haible.
4557 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4559 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4576 and Stepan Kasal <kasal@ucw.cz>
4578 Handle special characters in test case titles correctly.

4581 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4582 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4583 argument. Extend to check titles printed by ./micro-suite and

4586 Single-quote in a test title,
4587 Double-quote in a test title): Don't expect failure anymore.
4588 (Backslash in a test title): Put a non-whitespace character after the
4589 backslash so that Bourne shells might actually see it as an escape
4591 (Brackets in a test title,
4592 Pound in a test title,
4593 Comma in a test title,
4594 Quoted Macro in a test title,
4595 Macro in a test title,

4597 (Macro with backquote in a test title,
4598 Macro with double-quote in a test title,
4599 Macro with backslash in a test title): New tests expected to fail.
4600 * tests/torture.at (#define header templates): M4-quote this title in
4601 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4602 The visible effect was a stray [] in the testsuite output.
4604 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4606 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4607 `trap ... 0' inside a function, for AIX sh.
4609 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4611 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4612 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4613 5363) simply issues a warning when dividing by zero at compile
4614 time. Problem reported by Elias Pipping.
4616 2006-10-26 Eric Blake <ebb9@byu.net>
4619 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4620 show effect on macros that expand with commas.

4645 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4647 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4648 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4649 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4650 reported by Nelson H. F. Beebe for Coreutils 6.4.
4652 * tests/tools.at (autoconf --trace: user macros): Remove test
4653 for tracing multiline macros, since m4 1.4.7a uses a different
4654 way to number lines. Problem reported by Ralf Wildenhues.

4681 * doc/autoconf.texi (Caching Results): Likewise.
4682 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4683 AC_CACHE_CHECK_INT, since it's no longer public.
4684 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4685 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4715 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4716 looking for special shell characters.
4717 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4718 macro defined by AS_VAR_PUSHDEF before passing it as a

4730 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4732 (Imported from Automake.)
4733 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4734 which incorrectly sets the mode of an existing destination
4735 directory. In some cases the unpatched install-sh could do the
4736 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4737 system. We hope this is rare in practice, but it's clearly worth
4738 fixing. Problem reported by Alex Unleashed in
4739 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4740 Also, don't bother to check for -m bugs unless we're using -m;
4741 suggested by Stepan Kasal.

4749 is enabled by default with gnu and gnits strictness.
4750 Report from Bruno Haible.
4752 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4761 Import this change from Gnulib:
4763 2006-09-16 Karl Berry <karl@gnu.org>
4764 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4765 to avoid sectioning errors.

4774 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4775 (\code): must use new \...Char values, since now ` is active.
4777 2006-08-26 Karl Berry <karl@gnu.org>
4778 * build-aux/texinfo.tex (\textdegree): New command.
4780 2006-08-12 Karl Berry <karl@gnu.org>

4785 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4787 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4789 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4790 added to the template can get mangled.
4792 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4794 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4795 include the default headers, and redefine obstack_chunk_alloc
4796 and obstack_chunk_free. Fixes false failure with glibc.
4798 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4800 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

4815 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4817 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4818 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4819 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4820 Use a better substitute, by inspecting the output of "ls"
4821 rather than just using ":".
4822 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4823 rather than AS_EXECUTABLE_P, since we needn't worry about
4824 non-regular files here.
4826 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4827 due to configuration hassles with this. See Tonya Underwood's report
4828 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4835 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4837 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4839 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4840 initialization which is not inherited through the environment
4841 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4842 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

4847 problems with mkdir -p -m.

4851 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4852 comment about ac_cpp_err; it was incorrect, and anyway
4853 ac_cpp_err is being removed below.
4854 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4855 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4856 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4858 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4859 with werror_flag and conftest.err and so forth. This is more
4860 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4861 and anyway the user shouldn't normally want to see this gorp logged.
4862 Problem reported by Ralf Wildenhues.
4863 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4864 empty, not 'no', since the rest of the code uses 'test -z'.
4866 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4868 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4869 Use a single call to AC_DO_TOKENS rather than multiple, for
4871 (_AC_LINK_IFELSE): Test that resulting file is executable.
4872 Problem reported by mwoehlke in
4873 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4875 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4876 than creating a file to use with test -x; this is much faster.
4878 2006-10-02 Bruno Haible <bruno@clisp.org>
4880 * lib/autom4te.in (Automake-preselections): Add
4881 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4883 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4885 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4886 standard error, `experr' should be used, not `expout'.
4888 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4890 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4891 fseeko testing program twice; just use the earlier result.
4892 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4893 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4894 still doesn't let the program compile.
4895 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4898 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4899 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4900 include it, without including anything else.
4901 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4903 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4905 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4907 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4908 `error.h', and include it, for a `error_at_line' prototype.
4909 Use a nonempty format string in the link test.
4910 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4911 for a declaration of wait3.

5369 more globally, since the 2006-06-30 patch didn't suffice. Problem
5370 reported by Keith Marshall. Also, don't bother with builddir2,
5371 since it shouldn't be needed any more.
5373 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5375 * doc/autoconf.texi (Generic compiler characteristics):
5376 Document AC_COMPUTE_INT. Fix wrong statements on Default
5377 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5379 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
5380 (_AC_COMPUTE_INT): Add obsoletion warnings.
5381 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
5384 * NEWS: Document change.
5386 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5388 * doc/autoconf.texi (Volatile Objects): New section.
5390 * NEWS: Document previous change.
5392 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5394 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5395 Require that long long int be at least 64 bits wide. C99 requires
5396 this and enough programs depend on it so we should check for it.
5397 Bruno Haible reports in
5398 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5399 that long long int is 32 bits wide with some nonstandard compilers.
5400 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5402 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5404 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5405 to a nonexistent file, so that we don't have to worry about
5406 a local site configuration that doesn't use /usr/local.
5407 Problem reported by Keith Marshall in
5408 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5410 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5412 * doc/autoconf.texi: Be more consistent about using @acronym with
5413 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5414 quite right (it talked about "OSF/Tru64", even though the
5415 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5416 and it even mentioned "OSF 4"!) and at this point there's little
5417 reason to talk about OSF any more, since it died in 1994.
5418 (Specific Compiler Characteristics): Simplify example of
5419 negative-size array.
5420 (File Descriptors): Reorder to make the text flow better.
5421 Remove joke about "appreciate the various levels"; I didn't get it.
5422 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5423 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5424 (File Descriptors, Limitations of Usual Tools):
5425 Tone down the advice against renaming or removing open files.
5426 (Limitations of Usual Tools): Add a new section, on 'rm'.
5428 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5430 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5431 -lXt in LIBS, idea from Karsten Hopp; this was due since
5434 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5435 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5436 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5437 (which belong to Xt, not X itself). See Debian bug 327655.
5439 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5441 * configure.ac (AC_INIT): Bump to 2.60a.
5444 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5448 * configure.ac, NEWS: Update.
5450 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5452 * config/texinfo.tex: Sync from upstream.
5454 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5455 quadrigraph correctly in traces.
5457 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5460 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5461 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5463 * doc/autoconf.texi (Changed Directory Variables): New node,
5464 to document the whole `datarootdir' business a bit better.
5466 * tests/torture.at (datarootdir workaround): Extend test.
5467 Prompted by report by Alexandre Julliard.
5469 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5471 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5472 when using default mode of IBM C 6 for AIX. Problem and two-line
5473 fix reported by Larry Jones.
5475 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5477 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5478 about literal '${datarootdir}' if a definition is found in the
5481 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5483 * NEWS: Use "M4" rather than "m4" when appropriate.
5484 Problem reported by Eric Blake.
5485 * doc/autoconf.texi: Likewise.
5486 Use @acronym around BSD, GCC, and GNU when appropriate.
5487 (Why GNU M4): Renamed from "Why GNU m4".
5488 (Redefined M4 Macros): Mention that Posix
5489 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5490 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5493 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5495 * bin/autom4te.in (handle_output): Do not forbid the empty
5497 * tests/tools.at (autoconf: the empty token): New test.
5499 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5501 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5502 calls, so that we do not care whether they are LIFO or FIFO;
5503 in the m4_wrap, do not check which diversion is the topmost
5504 one, just check that the stack is balanced at the end.
5505 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5506 base diversion forever--pop the previous diversion before
5507 opening the new one; consequently, remove the m4_wrap call.
5508 * lib/autotest/general.m4 (AT_INIT): Likewise.
5509 * tests/m4sugar.at: Do not use
5510 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5512 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5513 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5515 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5516 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5517 Rework example of m4wrap token-pasting trouble so that it doesn't
5518 care whether it's LIFO or FIFO.
5519 Fix some "contrary to"s that are awkward in English.
5521 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5523 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5524 to `yes' instead of `int$1_t' if the type is found, for more
5525 consistent configure output (where $1 is the number of bits).
5526 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5527 Suggested by Bruno Haible.
5529 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5530 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5531 with system headers. Report by Bruno Haible.
5533 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5535 * config/config.guess, config/config.sub: Sync from upstream.
5537 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5538 in order to avoid picking up an older installed frozen m4sh.m4f.
5539 Besides an outdated shell startup, this could have been created
5540 by an earlier M4 version with incompatible frozen file format.
5542 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5544 * README: Recommend m4 1.4.4 instead of 1.4.3..
5545 * doc/autoconf.texi: Likewise.
5546 (Special Chars in Names): Say that $(.FOO) is portable, as
5547 suggested by Stepan Kasal.
5548 (Installation Directory Variables, Build Directories):
5549 (Automatic Remaking, Subdirectories, Fortran Compiler):
5550 (Making testsuite Scripts, Defining Directories):
5551 Quote variable usages better.
5552 (Making testsuite Scripts): Add clean-local rule to makefile
5553 snippet, by Eric Blake.
5554 (Installation Directory Variables): Fix table item font.
5555 Reword slightly to clarify. Generalize advice about
5556 not using special characters to include all file-related
5557 vars, not just VPATH.
5558 (Special Chars in Variables): Warn about special characters in
5560 (Assignments): Clarify default-value example as suggested by
5562 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5563 (Special Shell Variables): Note leading ./ or ../, as suggested
5565 (Limitations of Builtins): Under cd, warn about CDPATH.
5566 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5569 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5571 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5572 `@var', for texi2html.
5573 (Systemology): Some more word wrapping, for DVI output.
5574 (autom4te Invocation): The short option for `--melt' is `-M',
5577 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5579 * doc/autoconf.texi: More formatting and English tweaks,
5580 many suggested by Ralf Wildenhues.
5581 Reword to avoid "@code{...}'s" and the like, since it's ugly
5582 with Emacs info mode. discontents -> woes.
5583 Put a few "will"s back. time stamp -> timestamp.
5584 side-effect -> side effect.
5586 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5588 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5589 Warn about $@ not persisting. Problem reported by Julien Danjou in
5590 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5591 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5592 Mention other special chars, too.
5594 2006-06-14 Eric Blake <ebb9@byu.net>
5596 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5598 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5600 * doc/autoconf.texi: Some systematic minor improvements, as
5601 follows. Use "makefile" when talking about makefiles
5602 generally (which might be named "makefile" or "Makefile" or even
5603 "foo.mk"), "Makefile" when talking about a specific makefile
5604 called "Makefile". This unclutters the text from weird quotes
5605 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5606 values" rather than "@var{foo}s" and similar constructs containing
5607 "}s". Use "Make rules" rather than "Makefile rules". Minor
5608 English-language improvements. Change the prefix "sub-" to "sub"
5610 Put blank lines around examples more consistently.
5611 Avoid "rather" and "very" as intensifiers.
5612 Avoid "will" as an auxiliary.
5613 (Limitations of Make): Split this node into....
5614 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5615 (Leading _ in Macro Names, Backslash-Newline-Newline):
5616 (Backslash-Newline Comments, Long Lines in Makefiles):
5617 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5618 (obj/ and Make, make -k Status, VPATH and Make):
5619 (VPATH and Double-colon, $< in Explicit Rules):
5620 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5621 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5622 New nodes, resulting from splitup of Limitations of Make.
5623 All cross-references changed. Raise the top node from
5624 a section to a chapter, and all subnodes accordingly.
5625 Redo the introductory wording to match the new organization.
5626 (Installation Directory Variables): Use an example that is
5627 closer to what Autoconf actually does. Mention that VPATH's
5628 value should not contain metacharacters or white space.
5629 (Fortran Compiler): Fix a VPATH bug in an example.
5630 (Leading _ in Macro Names): Mention that this problem is no longer
5631 of practical concern.
5632 (VPATH and Make): Reword the advice to make it clearer
5633 that Autoconf and Automake support VPATH in non-GNU make, but
5634 many packages have bugs in this area.
5635 ($< in Explicit Rules): Refer to Build Directories rather
5636 than using a (non-VPATH-safe) example.
5637 (Automatic Rule Rewriting): Mention the sort of disaster that
5638 can ensue with Solaris-style rule rewriting with VPATH.
5640 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5642 * doc/install.texi (Compilers and Options): Weaken the
5643 suggestion to use GNU make for VPATH builds.
5645 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5646 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5648 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5649 in regular expression.
5651 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5653 * doc/autoconf.texi (Installation Directory Variables):
5654 Drop extra @samp from `@table @samp' item.
5655 (Limitations of Usual Tools): Comment fix.
5656 Do not nest @samp just to point to other table items.
5657 (Writing testsuite.at) <AT_CHECK>: The second argument to
5658 `@dvar' is already @samp'ed.
5659 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5660 do not use @var in the second argument.
5662 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5664 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5665 $as_shell.exe too. Problem reported by Andreas Buening in
5666 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5668 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5670 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5671 `unused variable' compiler warning, for `-Wall -Werror'.
5672 Reported by Jaap Haitsma in
5673 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5675 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5677 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5678 case the compiler dumps core. Problem reported for
5679 OpenServer 5.0.7 by Tim Rice in
5680 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5681 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5684 2006-06-06 Tim Rice <tim@multitalents.net>.
5686 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5687 "ERROR" only shows up in "make check" output if there is an
5690 2006-06-06 Eric Blake <ebb9@byu.net>
5692 * tests/tools.at (automatically allowed tokens): Fix typo.
5694 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5696 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5698 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5699 typically overflows on x86 CPUs, even though the C standard
5702 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5704 * configure.ac (AC_INIT): Bump to 2.59e.
5707 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5711 * config/texinfo.tex: Sync from upstream.
5713 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5714 seen, invoke libtoolize with `--ltdl' argument.
5715 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5717 Suggested by Eric Blake.
5719 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5721 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5722 reported by Ralf Wildenhues.

5725 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5729 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5731 * doc/autoconf.texi: Modernize some of the references to Solaris.
5733 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5735 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5736 message issued by AC_REQUIRE.
5737 * tests/m4sugar.at: Check m4_require's error message.
5738 * tests/base.at: Check AC_REQUIRE's error message.
5739 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5741 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5743 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5744 `expout' as the last parameter.
5745 * tests/tools.at: Adapt to the above change.
5747 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5749 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5750 information about race-free implementations of mkdir.

5759 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5761 * NEWS: GNU make now recommended for VPATH builds.
5762 Mention that some macros are now documented to be obsolescent.
5763 * doc/autoconf.texi:
5764 Prefer "current" to "modern" to describe
5765 currently-used (albeit perhaps old-fashioned) hosts.
5766 Mention which ancient features no longer need to be worried about.
5767 setgid -> set-group-ID
5768 setuid -> set-user-ID (these are the Posix terms)
5769 Fix some misuses of "only".
5770 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):

5781 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5782 Mention that it's now safe to use 3 and 4.
5783 (Limitations of Usual Tools): cp -r is now specified by Posix.
5784 Omit longwinded and obsolescent discussion of cp -f.
5785 Modernize discussion of expr, ls.
5786 (Limitations of Make): Modernize discussion of VPATH builds.
5787 Mention $? as a workaround in some cases.
5788 * doc/install.texi (Basic Installation):
5789 Mention "./configure; make; make install" first. Be more
5790 specific about why this file is generic. Remove unnecessary
5791 parens. Remove misleading "only". Remove obsolete advice
5792 about csh. Don't say "configure" takes awhile; say it
5793 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5794 and CC=c99 rather than CC=c89, as these are blessed by current
5795 Posix. Recommend GNU make if doing a VPATH build.
5797 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5799 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5800 examples involving shell prompts.

5803 and Paul Eggert <eggert@cs.ucla.edu>
5805 * doc/autoconf.texi (Here-Documents): Add details about the
5806 pre-ksh93g bug. Reword slightly to make it clearer. Consistently

5816 anywhere in directory names.
5818 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5820 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5821 about quoting the case statement, just in case.

5837 argument with leading hyphen. Problem reported by Paul Eggert.
5839 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5841 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5842 about quoting ac_try: quote all of it, if any of it seems suspicious.
5843 This means we don't have to worry about ${ or sed any more.
5844 Also, double-quote the case statement, to work around misuses via
5845 underquoting as reported by Ralf Wildenhues in
5846 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5847 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5848 undocumented and dangerous macro.
5849 Problem reported by Ralf Wildenhues in
5850 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5852 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5854 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5855 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5856 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5858 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5860 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5861 since evidently some packages rely on the old, broken behavior.
5862 Problem reported by Ralf Wildenhues in
5863 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5864 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5865 pre-2006-05-26 definitions, but leave in the comments that
5866 these macros are dangerous and should not be used.
5867 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5868 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5869 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5870 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5871 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5873 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5875 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5876 the use of 'tr', since this is our only use of 'tr'.
5878 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5879 and Paul Eggert <eggert@cs.ucla.edu>
5881 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5882 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5884 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5886 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5887 the output file in the `${datarootdir}' test.
5889 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5890 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5892 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5893 mention of `datarootdir' in the input file(s), but literal
5894 `${datarootdir}' in the output file, and we haven't warned yet,
5895 then warn as well: the user may have (erroneously) used
5896 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5897 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5898 * tests/torture.at (datarootdir workaround): Extend this test.
5901 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5902 and Paul Eggert <eggert@cs.ucla.edu>
5904 * doc/autoconf.texi (autoheader Invocation): The first argument to
5905 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5906 alternatives and clear up the language a bit.
5908 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5910 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5911 ac_config_guess, ac_config_sub, ac_configure.
5912 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5913 Fix typo that prevented an unnecessary space from being removed.
5914 Problems reported by Ralf Wildenhues in:
5915 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5917 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5919 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5920 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5921 Don't use the term "thread-safe" to talk about mkdir race
5922 conditions, since the problem is more a process than a thread
5923 issue. Problem reported by Stepan Kasal in:
5924 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5925 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5926 the test for 'install' more closely. Look at MKDIR_P first.
5927 Look in the PATH, and at /opt/sfw/bin.
5928 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5929 Don't bother to try mkdir -p, since we already check mkdir --version;
5930 just look at the version number. (There's no easy way to check
5931 for race-free implementations.)
5932 * tests/tools.at (autoconf: subdirectories): Adjust to above
5933 changes, since MKDIR_P now might end in "/mkdir -p".
5935 * doc/autoconf.texi (autoheader Invocation): Mention that the
5936 first arg of AC_DEFINE_UNQUOTED must be a literal.
5937 Problem reported by Ben Pfaff in
5938 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5940 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5941 * doc/autoconf.texi (Special Chars in Variables): New section.
5942 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5943 (Installation Directory Variables): Quote $(datadir) better.
5944 (Limitations of Builtins): Describe some of eval's trickiness.
5946 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5947 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5948 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5949 in front of every arg, not just trailing args. Quote apostrophes.
5950 (_AC_EVAL_ECHO): New macro.
5951 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5952 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5954 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5955 exposed by quoting of eval argument. Put the command on line line
5957 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5958 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5959 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5960 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5961 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5962 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5963 Use eval more safely.
5964 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5965 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5967 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5968 lines, exposed by quoting of eval argument.
5970 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5971 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5973 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5974 initialization of `ac_cv_exeext', do not override it if it was
5975 already set, unless it was set to `no', for compatibility with
5976 Autoconf-2.13, and comment this.
5977 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5978 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5979 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5980 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5981 Document that this test may be overridden by setting
5984 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5986 Revert these two patches:
5988 2006-04-06 Eric Blake <ebb9@byu.net>
5989 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5990 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5993 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5994 Clean up _AC_COMPILER_EXEEXT* macros.
5995 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5996 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5997 ac_file to the name of the default output file and call
5998 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5999 initial `rm' of the candidate files...
6000 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6001 the same list in subsequent `rm' calls, and for the temporary
6002 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6003 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6004 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6005 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6006 no longer needed) by libtool. Make it a cache check.
6007 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6008 copied here by mistake.
6009 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6010 _AC_COMPILER_EXEEXT.
6011 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6012 _AC_COMPILER_OBJEXT directly.
6013 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6015 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6017 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6018 Fix description of how the buggy `sed' works.
6020 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6024 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6025 ENOLCK. Only mention `make -j' when applicable. Only raise
6026 fatal errors when `make -j' is involved. Improve error message.
6028 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6030 * doc/autoconf.texi (Here-Documents): We now know more about
6031 the variable expansion in here documents bug.
6032 Thanks to Tim Rice and Stepan Kasal.
6034 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6035 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6037 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6039 * tests/autotest.at (Multiline command from M4 expansion):
6040 No failure to be expected if the shell quotes newlines in
6041 commands in the `set -x' output. Report by Tim Rice.
6044 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6046 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6047 expansion in the here-documents used by config.status, as that
6048 runs afoul of the Korn shell version M-12/28/93d bug described in
6049 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6050 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6051 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6053 2006-05-23 Jim Meyering <jim@meyering.net>
6055 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6056 Fix typo introduced with 2006-04-02 change. It reversed the sense
6059 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6061 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6062 ac_dB slightly, to save bytes in the script.
6063 Max out at 50 lines, rather than 96; this is more likely
6064 (though not guaranteed) to avoid obscure 'sed' failures.
6066 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6068 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6069 `tr -d -' as bad option argument. Work around this by deleting
6070 an unrelated character.
6071 Report by Tim Rice <tim@multitalents.net>.
6073 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6074 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6075 Stepan Kasal <kasal@ucw.cz>
6077 * doc/autoconf.texi (Particular Programs): Do not promise that
6078 we always prefer the GNU version of the program, and that we
6079 search according to PATH; both rules can have exceptions.
6080 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6081 AC_PROG_SED. Move descriptions of limitations
6082 to the Limitations of Usual Tools section.
6083 (Limitations of Usual Tools) <sed>: Mention script length
6084 limitations with Solaris /usr/ucb/sed.
6085 <grep>: Fix wording for empty alternative. Mention that -c and
6086 -l should not be combined, and that -E and -F should not be
6089 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6090 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6092 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6093 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6095 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6097 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6098 AC_DEFINE is now passed to m4_pattern_allow.
6099 * NEWS: Mention that; likewise for AC_SUBST.
6100 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6101 the parameter to m4_pattern_allow.
6102 * tests/tools.at: Add a check for that.
6104 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6106 * lib/autoconf/status.m4: Fix typos.
6108 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6110 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6111 only the files that this macro generates.
6113 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6115 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6116 the HP-UX sed limitation of 99 commands, labels do not count.
6117 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6119 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6121 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6123 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6124 Import the following fix from coreutils:
6126 2006-01-13 Jim Meyering <jim@meyering.net>
6128 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6129 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6130 not double-quote uses of that variable, to accommodate the rare
6131 case in which getmntent is available in none of the libraries
6132 checked. This happens at least on FreeBSD 5.0.
6134 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6136 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6137 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6138 some other programs unwisely rely on these undocumented vars.
6139 But put in warning comments about them.
6140 Problem reported by Ralf Wildenhues in
6141 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6142 * NEWS: Document that these variables are intended to go away.
6144 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6146 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6147 and set the language to C++ (analogous to the equivalent Fortran
6150 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6151 * doc/autoconf.texi (C++ Compiler): Document it.
6152 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6155 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6157 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6158 that caused config.status to generate 100-command sed scripts; the
6159 portable limit is 99.
6161 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6163 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6164 variable `ac_d' instead of `d' to avoid infringing namespace.
6165 Report by Ralf Menzel.
6167 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6169 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6170 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6171 * tests/tools.at (autoconf: subdirectories): New test, taken from
6172 the corresponding problem report by Ralf Wildenhues in:
6173 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6175 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6176 Quote some uses of shell variables if they might suffer unexpected
6177 globbing. This doesn't fix all instances of quoting problems that
6178 I found, just the easy ones that look safe.
6179 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6180 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6181 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6182 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6183 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6184 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6185 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6187 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6188 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6190 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6192 * bin/autoreconf.in ($help): Reword according to the manual.
6193 Suggested by Olly Betts.
6195 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6196 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6198 * bin/autoreconf.in: Pass the directory argument to
6199 `require_configure_ac'. Fix comment.
6200 * tests/torture.at (Configuring subdirectories): Expose this.
6201 Reported by Olly Betts.
6203 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6205 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6206 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6207 Automake as follows:
6209 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6210 `$configure_in' instead of `configure.in', to preserve
6211 directory component.
6213 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6215 * config/config.guess, config/config.sub, config/texinfo.tex,
6216 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6218 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6220 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6221 test for C99 conformance; (bool) 0.5 is an integer constant
6222 expression, but (bool) -0.5 is not. Problem reported by Fedor
6223 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6225 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6227 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6228 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6229 Warn about obsolete install-sh files. Remove stray sentence
6230 fragment and fix cross reference.
6231 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6232 install -d; this undoes the 2006-05-10 change.
6233 (MKDIR_P): Mark with AN_MAKEVAR.
6234 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6235 that we don't require $INSTALL to be thread-safe. Move comments
6236 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6237 of AC_PROG_INSTALL. Output a message saying that we're checking
6238 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6239 MKDIR_P instead of AC_SUBST.
6240 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6241 Special magic for MKDIR_P, too.
6242 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6244 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6246 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6248 Sync from Automake, as follows:
6250 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6251 * config/install-sh: Initialize IFS, so field splitting isn't
6253 * config/mkinstalldirs: Likewise.
6254 * config/missing: Remove superfluous quotes. Replace all uses of
6255 `[' by `test', for consistency, and for..
6256 * config/missing (sed_minuso, sed_output): New variables.
6257 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6258 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6259 Fixes `missing' to detect `--output' for help2man. Fixes
6260 PR automake/483. Report by Dennis J. Linse.
6261 (autom4te): Document in `missing --help'.
6263 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6265 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6266 * config/install-sh: Don't use 'path' to talk about file names,
6267 as per GNU coding standards. Close a race condition reported by Ralf
6268 Wildenhues and Stepan Kasal. There is still a race condition
6269 on hosts that predate Posix 1003.1-1992, but we can't help this.
6270 Don't mishandle weird characters like space on pre-Posix hosts.
6271 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6272 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6273 AC_PROG_MKDIR_P from AS_MKDIR_P.
6274 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6275 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6276 earlier editions are not (including Automake 1.8.3).
6277 Do not suggest mkinstalldirs for thread-safety.
6278 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6279 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6280 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6281 presence of special characters and race conditions.
6282 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6283 in Autoconf's name space.
6285 2006-05-10 Bruno Haible <bruno@clisp.org>
6286 and Paul Eggert <eggert@cs.ucla.edu>
6288 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6289 from Automake with minor changes.
6290 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6292 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6294 * config/install-sh: Update to Automake CVS version, as follows:
6295 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6296 * lib/install-sh: Simplify the expr implementation of dirname.
6297 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6298 * lib/install-sh: Handle --, and diagnose unknown options.
6300 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6302 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6303 `./autom4te' to create `./testsuite', since the `all' target
6304 will ensure its presence, but `installcheck' should not create
6305 the uninstalled wrappers.
6307 * tests/torture.at (Unusual Automake input files): Skip if we
6308 detect automake < 1.8.
6310 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6312 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6313 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6314 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6317 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6319 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6320 munge (multiple) white space and other oddities.
6321 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6322 single quotes in variable assignment.
6323 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6324 and similar failures by adding multiple spaces, tabs, and other
6326 Report and different test suggested by Francesco Romani
6327 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6329 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6330 single quotes, we only need to search for single quotes; this
6331 both simplifies the search pattern, and makes us less
6332 susceptible to `echo' variations for arguments not containing
6334 (_AC_ARG_VAR_VALIDATE): Likewise.
6336 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6338 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6339 `$*' and IFS concatenation issue with traditional shells and
6340 bash-2.04. Report by Seanster@Seanster.com.
6342 2006-05-03 Bruno Haible <bruno@clisp.org>
6344 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6345 precisely which Mac OS X versions have the od problem.
6347 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6349 * doc/autoconf.texi: Use @option systematically.
6351 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6352 and Bruno Haible <bruno@clisp.org>
6354 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6356 (Integer Overflow): Mention the special case of integer division
6359 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6361 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6362 traditional shells like the Solaris one that do not use the
6363 first IFS character for assembling `$*'.
6364 Prompted by a related report from autoconf_bug@nro.ca.
6366 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6367 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6375 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6377 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6378 in URLs to improve DVI formatted output (requires texinfo 4.6).

6386 `action-if-found' -> `action-if-true' and similarly.
6387 (Obsolete Macros): Likewise.
6388 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6389 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6390 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6392 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6394 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6397 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6400 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6402 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6403 /bin/sh set unsorted output.

6410 (Integer Overflow, Null Pointers, Buffer Overruns):
6411 (Floating Point Portability, Exiting Portably): New sections.
6412 (Writing Test Programs): Fix some langauge. Recommend exiting
6413 with status 1, not merely nonzero. Clarify exit declaration.
6414 (Run Time): Move C exit status stuff to new Exiting Portably section.
6415 (Systemology): Mention Posix and levenez. Update v7 reference.
6416 (Portable Shell): Mention the Posix shell.
6418 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6420 * bin/autoconf.as (me): Replace by as_me.
6422 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6424 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6425 since as_me isn't set yet.
6427 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6429 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6430 a few minor bugs in this area.
6432 * doc/autoconf.texi (Programming in M4sh): Comment out the
6433 documentation of AS_BASENAME, for now.
6434 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6435 (Limitations of Builtins) <basename>: Do not refer to
6437 * bin/autoconf.as (me): Don't use AS_BASENAME.
6438 (dir): Remove the unused variable.
6439 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6440 AS_DETECT_REQUIRED. All uses changed.
6441 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6443 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6444 (AS_BASENAME): Use "basename --" to protect against leading "-".

6446 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6447 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6448 (_AS_DIRNAME_PREPARE): Likewise.
6449 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6450 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6451 (AS_DIRNAME): Use "dirname --".
6453 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6455 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6456 of "run time" and "run-time" changed to "runtime", for consistency.
6457 * lib/autoconf/fortran.m4: Likewise (in comment).
6458 * lib/autoconf/functions.m4: Likewise.
6459 * lib/autoconf/general.m4: Likewise.
6460 * lib/autoconf/headers.m4: Likewise.
6462 * doc/autoconf.texi (Run Time): Document the exit status situation
6463 with more accuracy and detail.
6465 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6467 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6468 Archive is not officially `GNU' any more. Update URL.
6469 (Defining Directories): Likewise
6470 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6472 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6474 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6475 newline from the `trap' code to finish `config.log'; the NetBSD
6476 /bin/sh resets the exit status after an empty command, as
6477 documented in doc/autoconf.texi.
6478 Reported by Dalibor Topic <robilad@kaffe.org>.
6480 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6482 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6483 Suggested by Bruno Haible.
6485 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6487 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6488 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6489 Instead, just list the shells that we know work.
6490 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6491 changed. Be more cautious about the _cv_ variable.
6492 * tests/tools.at (Syntax of the shell scripts): Check the
6493 _cv_ variable once, at first, to avoid an internal autoconf error
6494 when sh -n does not work.
6496 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6498 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6500 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6502 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6503 use ">&-" since we're only 99.999% sure that this is portable,
6504 and since the MinGW bug is fixed in a different way.
6505 * lib/autotest/general.m4 (AT_INIT): Likewise.
6507 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6509 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6510 before opening config.log, to avoid hitting a bug on MinGW.
6512 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6514 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6515 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6516 This works around a MinGW bug reported by Eric Paire.
6517 Make sure that all writes to the log file append to it,
6518 rather than possibly losing data.
6519 * lib/autotest/general.m4 (AT_INIT): Likewise.
6521 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6523 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6526 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6530 * configure.ac (AC_INIT): Bump to 2.59d.
6532 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6536 * Makefile.maint (news-date-check): Do not require a leading `*'
6537 before the release date in NEWS.
6539 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6540 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6542 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6543 the instantiated file do not contain the string 'datarootdir'
6544 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6545 @mandir@, replace the reference '${datarootdir}' by the value.
6546 * tests/torture.at (datarootdir workaround): New test.
6547 * NEWS: Advertise this temporary fixup.
6548 Based on a patch by Bruno Haible, reported and analyzed by
6549 Paul Eggert and Noah Misch.
6551 2006-04-12 Eric Blake <ebb9@byu.net>
6553 * tests/autotest.at (Debugging a failed test): Fix comment.
6555 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6557 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6558 all the changes since 2006-04-07.
6560 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6562 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6563 succeeded, but `ln -s file dir' failed, take care to remove the
6564 leftover target before the next test, to prevent its spurious
6565 failure; also make sure `ln file dir' works before selecting it.
6566 Thanks to Keith Marshall for pointing this out.
6569 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6570 assignments in `at_debug_args', so that we put them correctly
6571 in the `run' script.
6572 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6573 Reported by Eric Blake.
6575 2006-04-11 Eric Blake <ebb9@byu.net>
6577 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6578 top-level tests after micro-suite has been run. Used in...
6579 (Debugging a successful test, Debugging script and environment),
6580 (Debugging a failed test): ...these new tests. The first of these
6582 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6583 macro, split out from...
6584 (AT_INIT): ...here, so that using -d also generates a run script.
6585 Document that -d inhibits top-level logging.
6586 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6587 inhibits top-level logging; debug scripts are created.
6589 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6591 * tests/autotest.at (Empty test, Empty check): New test to check it.
6593 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6596 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6598 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6599 the files if a problem appears. Make the empty *.at files
6600 read-only, too. Proposed by Ralf Wildenhues.
6602 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6604 * config/Makefile.am: Add comment to force updated Makefile.in.
6606 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6607 space only patch to this file, this patch causes the Makefile.in
6608 files that include freeze.mk to be updated, and thus have a
6609 newer time stamp again, which in turn makes a pristine CVS
6610 checkout have correct time stamps.
6612 * Makefile.maint (cvs-sv): New macro, to be used..
6613 (config.guess-url_prefix, config.sub-url_prefix)
6614 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6615 point to CVS text checkout of Gnulib files.
6616 (copyright-check): Bump current year.
6617 (announcement): Do not hard-wire `./announce-gen'.
6618 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6620 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6622 (wget_files): Update config.guess, config.sub, texinfo.tex by
6623 `wget-update', now that their URLs work again.
6625 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6627 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6628 Problem noted by Paul D. Smith.
6630 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6632 * doc/autoconf.texi: Remove unused words from word list.
6633 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6634 .x-sc_trailing_space: New files.
6636 * doc/standards.texi: Sync from gnulib.
6638 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6639 `LIBOBJDIR' as experimental.
6641 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6642 with a target directory; it's internally implemented as `cp'
6643 anyway, but since Autoconf advertises the possibility to use
6644 a target directory when LN_S is `ln -s', we need to find out.
6645 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6646 analyzed by Keith Marshall <keith.marshall@total.com>.
6650 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6652 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6653 confdefs.h as-is. In general, if it has backslash-newline or the
6654 like, then it doesn't work either to sort or to remove empty
6657 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6659 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6661 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6663 * lib/autom4te.in (Automake-preselections): Preselect
6666 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6668 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6669 apostrophe within a single-quoted string, as this is the usual
6670 tradition and is easier to read than '"'"'. Don't rely on the
6671 shell treating "$/" like '$/'. Use a more-consistent indenting
6674 2006-04-09 Eric Blake <ebb9@byu.net>
6676 * tests/autotest.at (Backquote command substitution),
6677 (Multiline backquote command substitution): Remove mistaken
6678 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6680 (Parenthetical command substitution, Multiline parenthetical
6681 command substitution): here.
6683 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6685 Import macros from gnulib (often changing their name).
6687 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6688 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

6701 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6703 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6704 suggest a #define rather than a typedef for _Bool, and mention

6715 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6716 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6717 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6718 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6719 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6720 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6721 (Coding Style). Don't mention m4_expand_once.
6722 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6723 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6724 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

6761 _AS_DETECT_BETTER_SHELL:
6763 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

6775 distinguish m4sugar macros.
6776 * tests/tools.at (autoupdating with aclocal and m4_include):
6777 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6778 test case by Noah Misch <noah@cs.caltech.edu>.

6791 * doc/autoconf.texi (Programming in M4sh): Document that
6792 AS_MKDIR_P exits the script on failure.
6793 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6795 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6814 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6816 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6817 whether `set' quotes correctly: redirect stderr of the tested
6818 `set', and use a subshell, for Ultrix; use `sed' instead of
6819 `grep' for zsh `set' which may write binary output; match only
6820 at the beginning of a line, to avoid false positives.
6821 In order to avoid false positives by unrelated variables with
6822 multiline content, put the dump algorithm in a subshell and
6823 unset all variables containing newlines (except some which are
6824 special to the shell). Warn about cache variables that are

6870 ac_config_<foo>s again, sometimes normalized, sometimes not.
6871 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

6873 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6874 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6875 2005-07-25 rewrite. Noticed by Noah Misch.
6877 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6878 _AC_PRESERVE_HELP_ORDER, ...

6885 for --help from Cygnus `configure.'
6887 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

7031 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7032 initial `rm' of the candidate files...

7039 no longer needed) by libtool. Make it a cache check.

7760 Factor functionality to..
7761 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7762 `AC_SUBST($1)' in the public version.
7763 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7764 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

7789 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7790 conftest.o, to see whether the compiler really obeys; rm the object
7791 file before and after the test and register it with ac_clean_files.

7817 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7818 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7819 by the function rather than ignoring it.
7820 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7821 comparing its address. Intel's interprocedural optimization was
7822 outsmarting the old heuristic. Problem reported by
7825 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7827 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7829 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7831 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

7834 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7836 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7837 before removing it (chmod -R u+rwx); there are three instances of this.
7839 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7840 Stepan Kasal <kasal@ucw.cz>
7842 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7843 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7844 make its content writable before removing it. Remove an errorneous
7845 comment from the end, where the logs of the failed tests are copied
7846 to the main log file.
7848 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7850 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7851 in case the computer is too quick. Double quote the configure.ac
7854 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7855 problems if the testsuite were running too fast.
7857 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7859 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7860 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7861 (which belong to Xt, not X itself). See Debian bug 327655.
7862 * NEWS: Mention this.
7864 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7866 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7868 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7870 * config/move-if-change: Don't output "$2 is unchanged";
7871 suggested by Ben Elliston. Handle weird characters correctly.
7873 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7875 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7876 calls, so that the final expansion of this macro is shorter.
7877 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7878 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7879 the cleanup there. Use AS_VAR_* macros, to be more general.
7880 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7882 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7884 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7886 2005-09-01 Stepan Kasal <kasal@ucw.cz>

7899 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7900 The previous patch didn't work, so try a better one.
7902 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7904 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7905 in the example. Reported by Bruno Haible.
7906 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7907 "if $undefined_var;" succeeds with my shell.
7909 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7910 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7911 but change the m4_divert_text to m4_divert_once.
7913 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7915 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7916 Work around bug in Solaris /usr/xpg4/bin/awk.
7917 The bug is present in at least Solaris 8 through 10.
7919 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7921 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7922 some evil values and relying on the fact that $* concatenates the
7923 parameters by the first character from IFS.
7925 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7926 Stepan Kasal <kasal@ucw.cz>
7928 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7929 first header appears, define AH_HEADER.
7930 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7931 Update limitations about when to call AC_CONFIG_HEADERS.
7932 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7933 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7934 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7935 ``Configuration Actions''; fix their index entries.
7937 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7938 options correctly. Process N-M as M-N if M is smaller than N.
7939 Process ranges correctly so that N-N will run only N.
7940 Sort and uniquify the tests that will be run. If there is more
7941 than one test, reinsert the banners for the tests.
7942 * tests/autotest.at (Keywords): Unmark XFAIL.
7944 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7946 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7947 before passing the macro name to AH_TEMPLATE.
7949 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7950 now opens log after option processing; in particular, --version
7951 and --help do not touch config.log.

7955 2005-08-22 Stepan Kasal <kasal@ucw.cz>

7963 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7964 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7967 * doc/autoconf.texi (Defining Symbols, Changed Results):
7968 Prepend to LIBS, not append, in examples.
7970 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7972 When building in place, set srcdir="."; suggested by Tim Van Holder.
7974 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7975 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7976 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7977 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7978 does not mean "no --srcdir option".
7980 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7982 * tests/autoscan.at (autoscan): New file.
7983 * tests/suite.at: Use it.
7984 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7985 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7987 * tests/autotest.at (Keywords): Test keywords combinations.
7989 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7991 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7992 add "2>&1"; gzip 1.2.4 prints help on stderr.
7994 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7996 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7997 was pushdef'ed twice while popped only once. Push it only once.
7998 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8000 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8002 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
8003 prefixed by mere "===", not "configure: === ".
8005 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
8007 * Makefile.maint: Update from Bison.
8009 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8010 "<tab>" in comment, so that the point is understandable.
8012 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8014 Rewrite substantial part of lib/autoconf/status.m4.
8015 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8016 and CONFIG_COMMANDS are not processed in four separate loops.
8017 Instead, there is one main loop. This alows that the common code
8018 is expanded only once, thus config.status (and configure) is smaller.
8020 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8021 the AC_LIST_FILES and cousins macros are no longer used.
8023 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8024 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8025 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8026 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8027 contain the initialization, nor the for loop, nor the associated
8028 commands; all these go to ...
8029 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8030 _AC_OUTPUT_CONFIG_STATUS.
8031 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8032 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8033 (_AC_OUTPUT_FILE): The creation of the sed script ...
8034 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8035 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8036 _AC_OUTPUT_MAIN_LOOP.
8037 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8038 _AC_CONFIG_COMMANDS): Use ...
8039 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8040 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8041 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8042 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8043 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8044 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8046 (_AC_CONFIG_UNIQUE): Update.
8047 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8048 Replaced by this ...
8049 (_AC_LIST_TAGS): ... new common macro.
8050 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8051 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8052 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8053 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8054 this didn't belong to the `config commands' section.
8055 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8056 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8057 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8058 to the `config commands' section either.
8059 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8060 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8062 ... and many changes to the comments nearby.
8064 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8065 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8066 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8067 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8068 (#define header templates): The comment at the top of the generated
8069 header now includes the name(s) of the source file(s).
8071 Several unrelated small changes:
8073 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8074 parameter to AC_DIAGNOSE.
8075 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8076 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8077 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8078 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8080 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8081 in AC_OUTPUT doesn't double-quote it either.
8082 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8085 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8087 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8088 versions of Portland Group compiler produce single- and double-quoted
8089 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8090 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8092 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8094 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8095 This is a corrected version of yesterday's patch.
8097 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8099 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8100 path, too; insert a "===" to emphasize the line.
8102 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8103 ac_cv_build_alias to ac_build_alias.
8104 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8106 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8107 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8108 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8109 (AC_ARG_VAR): ... here.
8110 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8113 Keep a list of all precious variables and process them with one simple
8114 for loop, instead of expanding all commands, or, OTOH, complicated
8115 processing of output of "set".
8116 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8117 variable names in new macro...
8118 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8119 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8120 a loop to assign all ac_env_* and ac_cv_env_* variables.
8121 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8123 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8124 its value to shell variable ac_precious_vars and call
8125 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8126 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
8127 _AC_ARG_VAR_VALIDATE.
8129 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
8130 and the AC_SUBSTs ...
8131 (AC_INIT): ... here.
8133 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
8134 the ac_subst_files section in config.log.

8148 They are generated by the Tru64 v5.1B shell.
8150 2005-07-05 Stepan Kasal <kasal@ucw.cz>
8152 Fix my changes from 2005-07-01; reported by Noah Misch.
8153 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8154 description, the macro now accepts only a single tag.

8163 versions of autoconf.
8165 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8167 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

8170 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8172 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8173 sed substitution command, so that we allow | in program prefixes
8174 and program suffixes. (& is a problem anyway; we're not fixing
8176 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8177 configure_input, top_builddir, srcdir, etc.
8178 * lib/autotest/general.m4 (AT_INIT): Likewise, for

8240 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8241 (AC_SUBST): Call it.
8242 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8243 the directory specific variables; but don't call it for configure_input.

8247 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8250 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8252 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
8253 directory have inherent problems with special characters like spaces,
8254 due to limitations in Make syntax. Problem reported by Alexandre
8256 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

8269 from Justace Clutter.
8270 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8271 variable into diagnostic. Make the diagnostic an error, not a warning,
8272 because we really don't support spaces and suchlike in dir names.
8273 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8274 Don't worry about backslashes in srcdir; it can't happen now.

8285 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
8287 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8288 that '\|' is not allowed in BREs; recommend using newline separated

8291 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8293 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8301 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8302 b, t, r, w commands require single space, while : cannot have any.
8303 (Special Shell Variables): Fix sed code this in the example.
8304 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8305 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8307 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

8315 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8317 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8318 * doc/autoconf.texi:
8319 Don't mention Solaris versions so much, if a
8320 problem is common to all extant versions of Solaris. Say "SunOS
8321 4" instead of "SunOS" for SunOS 4.
8322 (awk): Mention more of the limitations of traditional Awk.
8323 (cat): Don't talk about cat -v.

8339 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8341 * doc/autoconf.texi: "filesystem" -> "file system".
8342 "behaviour" -> "behavior".
8343 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8344 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8346 * lib/m4sugar/m4sh.m4: Likewise.
8347 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8348 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8350 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.

8363 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8365 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8366 -u, since it outputs chatter if the input files are the same.
8367 Problem reported by Ralf Menzel.
8369 2005-06-08 Derek Price <derek@ximbiot.com>
8371 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8372 renaming them since they are about to be redefined anyhow.
8374 2005-06-08 Derek Price <derek@ximbiot.com>
8376 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8377 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8378 Move m4_undefine to alphabetical order.
8380 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8382 * README: Recommend GNU M4 1.4.3 or later.
8383 * doc/autoconf.texi (Introduction): Likewise.
8384 Reword to avoid some formatting glitches.
8385 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8386 Clarify explanation of HP compiler bug.
8387 Redo example output tp match current CVS snapshot.
8388 Use @example.org in email addresses when the examples
8389 might get inadvertently cut-and-pasted into user code.
8390 Remove example of autom4te usage that doesn't seem to work now.
8391 Use modern AC_INIT (except when the example is meant to be
8392 shown with Autoconf 2.13).
8393 Update ksh info for Solaris 9 and later.
8395 Modernize description of Automake versions a bit.
8396 Don't claim a future version of Autoconf is near.

8402 follows its own advice about quoting better.
8403 Reword to avoid some formatting glitches.
8404 * doc/installt.exi: Reword to avoid some formatting glitches.
8406 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8407 Tru64 ksh pattern matching bug. Reported against Libtool by
8408 Albert Chin <libtool@mlists.thewrittenword.com> and
8409 Nicolas Joly <njoly@pasteur.fr>.
8411 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8413 m4_cdr of one-member list was [[]] (one-member list containing an
8414 empty string) instead of [] (an empty list. Callers were skewed to
8415 match this misbehaviour. As a consequence of this:
8416 - m4_foreach([x], [], [foo]) expanded to `foo', while
8417 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8418 This bug has been fixed:
8420 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8421 expand to an empty string; print error msg if called without
8423 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8424 misbehaviour; handle [] and [[]] correctly.
8426 2005-06-06 Stepan Kasal <kasal@ucw.cz>

8432 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8434 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8435 swallow records with more than 99 fields.
8436 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8437 parse the long line.
8439 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8441 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8442 swallow literals longer than 399. Reported by Ralf Wildenhues.
8443 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

8446 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8448 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8449 to gfortran, and make these the first two compiler names
8450 checked (following the general autoconf preference for gcc).

8454 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8455 (DISTCLEANFILES): Remove $(check_SCRIPTS).

8460 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8461 expression of unbounded size when processing the --list
8462 option. This runs afoul of a limit of 399 bytes per regular
8463 expression on AIX. Problem reported by Ralf Wildenhues.
8465 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

8468 * doc/autoconf.texi (Particular Headers): Reword example
8469 for multiline stdbool replacement.
8470 (Setting Output Variables): Reword text a bit. Don't
8471 give all the details about |#_!!_#|.
8472 Reword description of line replacement.

8476 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8477 now contain newlines, and substituted files must be referenced on
8478 a line alone; the sed scripts to substitute them are now very
8480 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8481 commands can be put in a sed script portably.
8482 * doc/autoconf.texi (Setting Output Variables): Document above
8483 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8484 use of multiline substitution.

8495 classes in shell scripts. The test was too brittle.
8497 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8499 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8500 * doc/autoconf.texi (Limitations of Builtins): Document this
8503 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8505 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8506 common code; used in many places in the tree.

8513 messages when ac_unique_file is not found.
8514 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8515 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8516 commands, for consistency with AC_MSG_ERROR and such.

8531 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8532 (ac_top_builddir): ... this ...
8533 (ac_top_build_prefix): ... to this; the old name is also kept, for
8534 backward compatibility.

8551 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8552 argument to m4_foreach. I guess it was necessary in the past,
8553 but I think it's a no-op now.

8557 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8558 ``cat <<_ACEOF'' commands to one.

8564 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8566 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8567 the wrong patterns between ``case'' and ``esac.'' The previous

8636 * doc/autoconf.texi (Autoconf Language): Be more precise about
8637 quoting rules. Problems noted by Stepan Kasal.
8638 Also, throughout this document, be more careful about white space.
8639 "blank", "white space", and "space" all have different meanings
8640 and we should be careful to say what we mean.

8661 set by latest automake.
8663 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8665 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"

8679 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8680 by AC_DEFINE; it was a mistake.
8681 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8683 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8685 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8687 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8689 * doc/autoconf.texi (External Software): Quadrigraphs are not
8690 processed correctly in AS_HELP_STRING; avoid this in the examples.
8691 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8692 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8693 comment and reduce m4_default([foo], []) to [foo].
8694 (m4_strip): Update the explanation.
8696 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8698 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

8700 Problem reported by Jennis Pruett.
8701 * lib/autoconf/functions.m4
8702 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

8752 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8753 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8754 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8756 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8758 * NEWS: The configure command now warns you if you attempt to use
8759 a directory whose name contains a special character like space,
8761 * doc/autoconf.texi (Installation Directory Variables): Allow
8762 "," in file names. Do not use \@; it's not a portable regexp.

8774 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8775 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8776 ac_pwd, and quote srcdir.
8777 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8779 * doc/autoconf.texi: Fix some systematic formatting problems.
8780 ".)" needs a following @: if not at the end of a sentence, and
8781 similarly for "!)". "etc." should be preceded by a comma.
8782 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8784 2005-03-22 Bruno Haible <bruno@clisp.org>
8786 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8787 argument is often called 'build-aux'.
8789 2005-03-07 Stepan Kasal <kasal@ucw.cz>

8798 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8799 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8800 from a Common Lisp's `cl'.
8801 (AC_PROG_CXX): Behave according to the documentation: don't
8802 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8803 make the variable CCC precious; use `cl.exe', not `cl'.
8805 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8806 Alexandre Duret-Lutz <adl@gnu.org>
8808 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8809 /dev/null, as "configure" shouldn't read stdin, and this insulates
8810 us from problems (e.g., when testing for "cl"). Also, do this
8811 redirection before invoking "hostname" or "uname", and keep the
8812 original input stream available via...
8813 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8814 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

8826 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8827 newline if neither \c nor -n work, as that would output two
8828 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8830 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8832 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

8836 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8838 Undo previous change, except keep the change to
8839 lib/autoconf/programs.m4 that replaced grep with shell
8840 pattern-matching. This is because net-snmp configure reads stdin.
8841 Reported by Noah Misch.

8845 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8846 from /dev/null, as "configure" shouldn't read stdin, and this
8847 insulates us from problems (e.g., when testing for "cl").
8848 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8849 before invoking "hostname" or "uname".
8850 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8851 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8852 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8853 "</dev/null" since it's now done at the top of 'configure'.
8854 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8855 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8856 Also, replace grep with shell pattern-matching, to save a process.
8858 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8860 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8861 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8862 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8865 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8867 * doc/autoconf.texi (Limitations of Usual Tools): Document that

8869 Problem reported by Dan Manthey.
8871 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8873 * doc/autoconf.texi (Special Shell Variables): Clarify
8874 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8876 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8878 * doc/autoconf.texi: Use @acronym for DJGPP.
8879 Fix some @code's that should have been @env's, and vice versa.
8880 Sort environment variable names.
8881 Mention that shells no longer inherit IFS.
8882 Don't recommend PATH_SEPARATOR=';' so strongly.
8883 Mention that $RANDOM might expand to the empty string.
8884 "symlink" and "soft link" -> "symbolic link".
8885 Improve mktemp description (reported by Bruno Haible).

8961 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

9024 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9025 Update the long comment explaining it.
9027 m4_require no longer writes an ``is required by'' line to the
9028 execution stack. It contains only one bit of non-redundant
9029 information: that the macro was required, not called. And even
9030 this bit is useless in most situations: have you ever met a macro
9031 which both calls and requires the same macro?
9033 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9034 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9036 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9037 (m4_expansion_stack_pop): Remove the misplaced comment.
9038 (m4_require): Don't put the ``is required by'' line to the
9039 execution stack; slightly improve the out-of-a-defun error message.
9040 (_m4_divert_grow): New macro, counter for the temporary diversions.
9041 (_m4_require_call): Use it.
9042 * tests/m4sugar.at (m4_require): Expect output without the
9043 ``is required by'' messages.
9045 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9047 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

9453 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9454 "char c = '\200';" rather than "char c = 0x80;" as the

9520 the $1_found variable, don't test whether the file is executable;
9521 Both things are checked ...
9522 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
9523 the former ``test -f''.
9524 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
9526 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

9534 limitations. Reorder paragraphs for clarity.
9536 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
9538 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9539 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9540 variants", "Unix", and some related minor wording fixups.
9542 (Shellology, Special Shell Variables): Document that the Zsh
9543 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9544 to Alexandre Duret-Lutz for this info.
9546 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>

9565 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9567 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9568 readable; it's not true in OS/2-emx.
9570 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9572 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9573 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9574 (trivial change). Problem and patch reported by Andrew Church in:
9575 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

9604 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9605 texinfo.tex for now (done by hand now).
9606 * Makefile.maint (wget_files, cvs_files):
9607 Remove ansi2knr.c; nobody uses it.
9608 (ansi2knr.c-url_prefix): Remove.
9609 (cvs-update): Fix test for failure. I don't know why it ever
9612 * doc/autoconf.texi: Update URLs, some of which went stale.
9613 Use @uref rather than @href.
9615 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9616 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9618 * config/config.guess, config/config.sub, config/elisp-comp,
9619 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9620 doc/fdl.texi, doc/standards.texi: Sync with master copy.

9630 Use "file name" rather than "filename" or "path",
9631 to be consistent with the terminology of the GNU coding standards.
9633 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9635 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9636 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9637 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9638 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9640 More fixes to support spaces in the name of the build directory.
9641 This isn't a complete fix but it's an improvement.
9643 * bin/autoconf.as (autom4te_options): New var.
9644 Use it instead of appending to AUTOM4TE, so that we can allow
9645 spaces in the build directory's absolute name.
9646 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9647 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9648 AT_CHECK_NOESCAPE): Likewise.
9649 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

9661 and isnan. From a suggestion by Kevin Ryde.
9663 * lib/Autom4te/General.pm (END): Return correct exit status even
9664 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9666 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9668 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9669 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9670 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9672 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9674 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9675 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9676 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9677 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9678 * lib/autom4te.in (Automake-preselections): Preselect
9679 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9681 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9683 * lib/autom4te.in (Automake-preselections): Preselect
9684 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9687 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

9694 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9696 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9697 with pdksh, too. Problem reported by Patrick Welche via
9699 * doc/autoconf.texi (Shellology): Note that set -o posix is
9700 useful for pkdsh, too.
9702 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9704 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9705 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9706 Don't fail if ENV or BASH_ENV is readonly.
9707 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9708 etc. are read only. Problem reported by Ludovic Courtes.
9710 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9712 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9713 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9716 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9718 * doc/autoconf.texi (File System Conventions): Warn about
9719 names like "aux". Problem reported by Eric Blake.
9721 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9722 by zero instead of array size, so that we can use any arithmetic
9723 constant expression (instead of requiring an integer constant
9724 expression). This allows us to test expressions like DBL_MAX <
9725 LDBL_MAX, which didn't conform to the C standard using the old
9727 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9728 now that we can do floating-point tests at compile time.
9730 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9732 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9733 and LDBL_EPSILON, as the resulting expression isn't an
9734 integer constant expression and violates the C standard.
9735 Problem reported by Nelson H. F. Beebe. Also, check
9736 for "L" suffix, and check that long double doesn't have
9737 worse range or precision than double, that mixed-mode
9738 arithmetic doesn't generate a diagnostic, that double
9739 constants fit in long double.
9741 2004-06-03 Kevin Ryde <user42@zip.com.au>
9743 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9744 malloc(0) and realloc(NULL,size).
9746 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9749 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9751 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9752 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9755 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9757 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9758 can be rewritten using if-then-else. Suggested by Bruno Haible.
9760 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9762 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9763 Problem reported by Stepan Kasal.
9765 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9767 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9768 change). Patch reported by Ralf Wildenhues in
9769 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9771 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9772 function F exists if the compiler and linker let you compile an
9773 expression like (F != 0). Recent versions of GCC optimize away
9774 the reference to F in that case, since every function address must
9775 be nonzero, so the link succeeds even if F does not exist.
9776 Problem reported by Manu in
9777 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9779 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9780 "Unix". Many uses changed.
9781 (Limitations of Builtins): Explain better why the ! command isn't
9784 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9786 * lib/autom4te.in (Automake-preselections): Preselect
9787 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9789 2004-05-19 Kevin Ryde <user42@zip.com.au>
9791 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9792 referencing AC_FUNC_STRERROR_R.
9794 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9795 note pessimistic assumption when cross compiling.
9797 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9799 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9800 (until 2004) invoked subcommands with sh -e, contra POSIX.
9801 Reported by Kevin Ryde.
9803 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9805 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9806 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9807 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9808 `test -f " /usr/bin/grep"', which _always_ failed.
9809 (AC_PROG_SED): Ditto bogus PATH fix.
9810 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9811 requires that grep correctly supports _multiple_ `-e' options, rather
9812 than stating only that grep should accept `-e'.
9814 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9816 Port to C99, which requires that 'exit' be declared.
9818 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9819 to ensure that stdlib.h is included.
9820 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9821 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9822 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9823 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9824 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9825 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9826 when using 'exit' in a test; C99 requires that 'exit' be declared.
9828 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9830 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9831 now prefers 'grep' implementations that accept -e.
9832 (Limitations of Usual Tools): Describe problems of traditional
9833 egrep and fgrep with long input lines, and of traditional grep
9835 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9836 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9837 All callers changed. Append /usr/xpg4/bin to the PATH, for
9839 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9840 the user with complaints about multiple -e options.
9841 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9842 Define it with AC_PROG_GREP.
9843 * configure.ac (AC_PROG_GREP): Add.
9844 * lib/freeze.mk (GREP): New macro.
9846 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9848 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9849 a possible candidate only after all others fail, rather than
9850 consulting it first. This improves backward compatibility by
9851 better reflecting the way shell selection occurred in previous
9852 versions of Autoconf, and should help to avoid triggering latent
9853 problems in other packages, such as the one in Automake where zsh
9854 is not handled robustly:
9855 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9856 Although it is not Autoconf's responsibility to work around
9857 problems in Automake, it nevertheless makes sense to avoid
9858 introducing unnecessary incompatibilites.
9860 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9861 Gary V. Vaughan <gary@gnu.org>
9863 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9864 how deeply nested we are when a suitable tool is found, set the
9865 ac_path_TOOL_found flag.
9866 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9867 nested we are in this macro. Break out of all 3 nested loops if
9868 ac_path_TOOL_found is set.
9870 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9872 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9873 of the _AS_PATH_WALK loop too if GNU flavor is found.
9875 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9877 * doc/autoconf.texi (Limitations of Make): Update documentation
9878 for `$<'. New entry `Long lines', based on a report from Simon
9879 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9880 paragraph about DJGPP, based on a mail from Richard Dawe.
9882 2004-04-20 Paul Eggert <eggert@twinsun.com>
9884 * tests/c.at (C keywords): Don't assume that GCC supports
9885 "restrict" and "inline", as sufficiently-old GCC versions do not
9886 (also, GCC configured to be in pedantic C89 mode does not).
9887 Problem reported by Sumit Pandya in:
9888 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9890 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9891 consider -g to work if it generates warnings when plain compiles
9892 don't. Problem reported by Braden McDaniel in:
9893 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9895 * doc/autoconf.texi (Slashes): New section, to document a problem
9896 reported by Jim Meyering in:
9897 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9899 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9900 linker output files before linking, to work around IRIX 6 linker bug.
9901 Problem reported by Rainer Orth in:
9902 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9904 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9906 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9907 best tool so far counter rely on the tool path variable name to
9908 avoid checks for one tool being affected by the results of running
9909 the length check on a previous tool.
9911 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9912 match expression argument, as different greps have different
9913 regular expression flavours.
9914 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9916 (AC_PROG_EGREP): Pass 'EGREP$'.
9917 (AC_PROG_GREP): Pass 'GREP$'.
9919 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9921 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9922 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9924 2004-03-29 Paul Eggert <eggert@twinsun.com>
9926 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9927 Types, Specific Compiler Characteristics, System Services,
9928 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9929 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9930 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9931 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9933 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9934 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9935 AC_TYPE_OFF_T): Likewise.
9936 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):

9942 2004-03-28 Paul Eggert <eggert@twinsun.com>
9944 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9945 now defines HAVE_DECL_TZNAME if it is declared, when
9946 HAVE_STRUCT_TM_TM_ZONE is not defined.
9947 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9948 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

9953 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9954 superfluous backslashing of quotes (") in sed expressions;
9955 thanks to Paul Eggert.
9957 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9959 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9960 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9961 H. F. Beebe for the bug report.
9963 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9965 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9966 quoted -cmdline argument in Portland Group compiler (bug
9967 reported by Jeffrey J. Barteet).
9969 2004-03-25 Kevin Ryde <user42@zip.com.au>
9971 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

10000 * doc/autoconf.texi: Avoid macros with unbraced arguments,

10017 * bin/Makefile.am (edit): Don't use $< in a context where
10018 POSIX doesn't require support for it. Use $@.in instead.

10036 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10037 problem on QNX reported by Stephen Rasku in

10040 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10041 $(m4sh_m4f_dependencies); this removes a FIXME.
10042 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.

10044 one per related section. Add $(srcdir)/wrapper.in.

10049 AC_SUBST provides no portable way to escape literal newlines.
10051 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10052 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10053 Darwin uses -lcrt2.o and there's little point to cataloging all
10054 the system variants. Partial fix reported by Andreas Waechter in:

10097 trigger the bash bug anymore.
10098 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10099 use AS_INIT_WITH_SHELL_FN.
10100 * bin/autoconf.in, tests/wrapper.in: Regenerated.

10130 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

10132 the 2003-05-22 change, which removed the older years from the list.
10133 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

10144 egrep and fgrep respectively if $GREP -E/-F don't work.
10145 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10146 _AC_PROG_GREP, and AC_PROG_SED.
10147 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10148 longest input length accepted by a command.

10179 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10180 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10181 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10182 not <inttypes.h>. Problem reported by Tim Mooney in
10183 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10184 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10187 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10188 otherwise "make check" fails because it forbids cmp (I guess
10189 because cmp treats files as binary on DOS-like systems).
10191 * tests/mktests.sh: Update copyright date to 2004, since some tests
10192 have changed in 2004.
10194 2004-01-23 Gary V. Vaughan <gary@gnu.org>

10197 non-truncating sed or gsed program in PATH.

10202 2004-01-15 Paul Eggert <eggert@twinsun.com>
10204 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10205 -std1 disables some useful extensions on Tru64. Problem reported
10206 by N. Lichtmaier in

10211 * doc/autoconf.texi (Programming in M4sh): Document that
10212 AS_MKDIR_P succeeds if the destination is a symbolic link
10213 to an existing directory.
10214 (Limitations of Usual Tools): Note that mkdir -p might not
10215 succeed on symlinks to directories.
10217 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10219 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10220 * bin/autoheader.in: Grammar fix in message.
10221 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10222 Test for dir before calling mkdir -p. (trivial changes)

10233 2004-01-09 Paul Eggert <eggert@twinsun.com>
10235 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10236 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10237 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10238 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10239 AC_COMPILE_IFELSE, since we now assume our caller invokes
10240 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10241 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10242 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10243 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10245 2004-01-07 Paul Eggert <eggert@twinsun.com>
10247 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10248 `"'...'"`, as it's confusing (and I suspect it may not work on
10249 some platforms). The code was incorrect anyway, as it assumed
10250 that \$ evaluated to itself in that context. Reported by
10251 Alexandre Duret-Lutz.
10253 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10255 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10256 and _LT_AC_TAGCONFIG.

10281 2004-01-04 Paul Eggert <eggert@twinsun.com>
10283 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10284 Use "rm -f" to remove conftest.sed, not plain "rm".
10285 Bug reported by David Relson in
10286 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10288 * Makefile.am (autom4te-update):
10289 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

10306 -c -o might not work. From a suggestion by Kevin Ryde.
10307 (C Compiler, Generating Sources, Limitations
10308 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10309 Don't put '-o' after non-options, as POSIX doesn't allow this.
10310 Mention that cc's name might be gcc or c89 or whatever.
10312 2004-01-04 Kevin Ryde <user42@zip.com.au>
10314 * doc/autoconf.texi: Add various further index entries.

10323 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10324 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

10326 explanation clearer.

10337 * tests/atlocal.in: Store the result here.
10338 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

10340 of explicitly testing.
10341 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10342 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10343 * tests/tools.at (Syntax of the shell scripts): Simplify

10428 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10429 than $target since the latter is not usual, add guidelines on when to

10611 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10612 -mGLOB_options_string stuff for Intel ifc, which can cause

10636 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10637 cache variable instead of $G77 to decide whether to include -O2,
10638 since $G77 is specific to Fortran 77.

10642 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
10643 free" flag. Re-order flags tested into rough order of popularity.
10645 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10647 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10648 arguments so that it can be used with syntax identical to
10649 AC_PROG_F77, and so that we can more easily decide to
10650 remove/deprecate the DIALECT optional argument in the future if it
10651 proves troublesome.
10652 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10653 non-freeform-supporting compilers. Document freeform flags.
10655 2003-10-03 Akim Demaille <akim@epita.fr>

10717 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10718 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10719 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

10724 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10725 directory for AC_CONFIG_COMMANDS' first argument exists.
10726 This makes valid the invocation of _AC_SRCPATH that follows.
10727 Reported by Eric Sunshine.

10751 The test suite are sometimes assigning timings incorrectly.
10752 Reported by Henk Krus.
10753 Diagnosed by Nicolas Joly.
10755 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10757 Instead of making AT_help a sequence of assignments to grow
10758 $at_help_all, just make AT_help_all be the growing contents of
10759 $at_help_all, and make a single assignment in...
10761 (at_times_skip): Flip the meaning and rename as...
10762 (at_times_p): this.
10763 (AT_INIT): When summarizing the test that ran, remove

10773 (ifnames): chmod -w.
10774 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10775 executables, not bin/ executables! Otherwise all the magic needed
10776 to find non installed files is turned off. This caused a failure
10777 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10778 as found in its environment (sent by tests/autoreconf): pointing
10779 to bin/autom4te that could not find its files.
10780 * tests/mktests.sh: Force the replacement of generated files, for
10781 the sake of "mv" program that are interactive when overwriting a

10790 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10791 Paul Eggert <eggert@twinsun.com>
10793 Trivial change to support GCC's configuration procedure.

10829 willing to edit the output files.
10831 2003-09-10 Akim Demaille <akim@epita.fr>

10834 and AC_FC_FREEFORM.
10835 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10836 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

10876 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10878 Add support for newer Fortran dialects. The F77 interface is
10879 unchanged, and continues to support Fortran 77. New FC macros
10880 correspond to all the old F77 macros, with output variables FC,
10881 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10882 available dialect, but older dialects can be specified. There are
10883 new macros AC_FC_SRCEXT to set the source extension, and
10884 AC_FC_FREEFORM to accept free-form source files.
10886 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

11010 2003-08-21 Akim Demaille <akim@epita.fr>
11012 First stab at preserving warnings between calls to autom4te,
11013 including when the cache is used.
11015 There are still several issues: (i) there are too many runs of m4
11016 (one for include, one for warnings, and some more), (ii) warnings
11017 spreading on several lines are not handled gracefully, (iii) the
11018 code meant to have the call stack display for errors does not work
11019 (its handling should move from m4 to autom4te).
11021 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11023 (@preselect): Add m4_warn.
11024 ($exit_status): Remove, use $exit_code.
11025 ($help): Use Autom4te::ChannelDefs::usage.
11026 (&handle_m4): No longer define the m4_warnings.
11027 At each run, extract and report the warnings.
11028 Always cache the result, including if the exit status is on
11029 failure, since if nothing changes, we should result in the same
11030 failure, hence we can use the cache.
11031 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11032 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11034 (m4_warn): Redefine as a do-nothing: it is its invocation that
11035 matters, as warnings are now reported via traces.
11036 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11037 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11038 the latter reveals calls to the former.
11042 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

11075 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11076 * bin/autom4te: Adjust.
11077 In particular, be Autoconf tools are really silent when properly
11078 working, bind the verbosity of the 'note' channel to $verbose.
11079 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

11203 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11204 not all of them. This fixes 1. the fact that when testing
11205 Autoconf there are many many config.log, 2. the incorrect use of
11206 top_srcdir to find config.log.
11207 Don't mix the detailed output of failed test with the summary of
11208 failures. Rather, append detailed log afterwards.
11210 2003-06-23 Akim Demaille <akim@epita.fr>
11212 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

11327 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11328 Remove `#include <stdlib.h>' from the list; we should never
11329 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11330 resulting namespace pollution would cause other tests to fail.
11331 Configure scripts run with some older versions of g++ and HP's
11332 aCC would fail due to such an #include. Problems reported by
11333 Matthew Mueller in <http://bugs.debian.org/120704> and by
11335 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11336 In the test, use the test declaration before including <stdlib.h>,
11337 as that's closer to how it'll be used.

11344 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11346 Overhaul Autotest's logging: generate separate log files
11347 in testsuite.dir/NNN/testsuite.log, and append them to
11348 testsuite.log instead of re-running the test verbosely.
11350 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11351 file descriptor, write 0 to at_status_file instead of setting
11352 at_status=0, initialize some new variables (at_status_file,
11353 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11354 to rerun the tests, instead append the at_group_log to the
11355 at_suite_log when a test fails.
11356 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11357 with the AS_MESSAGE_LOG_FD redirected to stdout.
11358 (AT_CLEANUP): save the output status in $at_status_file
11359 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11360 its original place.
11361 (AT_CHECK): since tests are run with a redirected stdout,
11362 and used to be re-run in verbose mode, turn some $at_verbose
11363 into echo, and don't redirect the output of testing stdout

11487 2003-05-06 Akim Demaille <akim@epita.fr>
11489 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11490 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11491 by aclocal.m4 is changed it might require the importing of another
11492 m4 extension file, i.e., aclocal must be run.

11748 gettimeofday and many other functions.

11765 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11766 defined, to support freestanding compilers. This should fix the
11767 bug reported by Momchil Velkov in

11770 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

11806 * Makefile.maint: Sync with Bison, i.e.:
11807 (po-check): Scan .l and .y files instead of the

11811 Look for N_ as well as for _. Try to avoid matching #define for

11828 than assigning in main, to avoid HP cc +O3 optimizing it away.
11830 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11832 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11833 option. Process --recheck after parsing all options. Pass -q

11870 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11872 We _have_ to stop using the old compatibility scheme that tried to
11873 avoid useless backslashes because Libtool 1.4.3 contains a
11874 AC_DEFINE([error_t], [int],
11875 [Define to a type to use for \`error_t' if it is not
11876 otherwise available.])
11877 We _have_ to quote the single quote and backslashes with \. The
11878 old compatibility scheme saw that ` was backslashed, and therefore
11879 did not quote the single quote. Hence before this patch, Autoconf
11880 was not compatible with Libtool.

12271 Reported by Alexandre Duret-Lutz.
12273 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12277 (&freeze): Use &error.
12278 (&up_to_date): If a file that was included according to the cache
12279 is no longer there, then the output is out dated.

12293 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12294 if some file was changed instead of `print'.
12295 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

12329 file name to enable parallel executions.
12330 From Sam Varshavchik.
12332 2002-10-08 Akim Demaille <akim@epita.fr>
12334 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12335 aclocal invocation, as Gettext macros might not be visible to
12337 Instead of blindly running autopoint, scan configure.ac (not the
12338 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12339 Reported by Paul D. Smith.
12341 2002-10-08 Paul Eggert <eggert@twinsun.com>
12343 Work around problems found when POSIXLY_CORRECT=1 is set.
12344 None of this seems to have anything to do with POSIX, really,
12345 but it's how Perl getopt works.
12346 * bin/autom4te.in (parse_args): Configure GetOpt with
12348 * doc/autoconf.texi (Invoking autom4te):
12349 --warning -> --warnings.

12371 * tests/torture.at (Configuring subdirectories): Be robust to
12372 users who use config.site to require for a cache: in this case,
12373 the two last configure runs, using two different sets of
12374 arguments, trigger a legitimate error.
12376 2002-09-28 Akim Demaille <akim@epita.fr>
12378 * tests/m4sh.at (Functions Support, Functions and return Support):
12381 2002-09-28 Akim Demaille <akim@epita.fr>
12383 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12384 autoheader are Perl programs.

12409 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12410 (.m4.m4f): Don't pass --prepend-include, since that's done by
12411 tests/autom4te itself.
12412 * lib/autoscan/Makefile.am: Include freeze.mk.
12413 (autoscan.list): New target --this file is no longer a source.
12414 (autoscan.pre): New file.
12416 2002-09-28 Akim Demaille <akim@epita.fr>
12418 * bin/autoscan.in (@kinds): Make them singular.
12420 (&init_tables): When --debug, report the list of rules to ease
12421 tracking changes in autoscan.list.
12422 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12424 2002-09-28 Akim Demaille <akim@epita.fr>

12434 * lib/autoscan/functions, lib/autoscan/headers,
12435 * lib/autoscan/identifiers, lib/autoscan/makevars,
12436 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12437 `functions' line is now prefixed with `function:'.
12438 * bin/autoscan.in (&init_tables): Adjust.
12440 2002-09-28 Akim Demaille <akim@epita.fr>
12442 From now on, autoscan files must always map a macro name to a
12443 word: there is no `default' macro for autoscan.
12445 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12447 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12450 2002-09-28 Akim Demaille <akim@epita.fr>
12452 * bin/autoscan.in (%c_keywords): Remove.
12453 (&used): Keep only track of the words we might be interested in.
12454 (&output_kind): It is no longer needed to look for non active

12468 Thanks to Bill Moseley and Paul Eggert.
12469 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12470 the tmpdir must be created.
12471 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12472 dir be in the build tree, instead of $TMPDIR.
12474 2002-09-27 Akim Demaille <akim@epita.fr>
12476 * bin/autoscan.in: Improve the comments.
12477 (&parse_args): Drop obsolete undocumented options.

12485 Reported by Ralf Corsepius.
12486 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12488 2002-09-26 Akim Demaille <akim@epita.fr>
12490 Single suffix rules and seperated dependencies are not portable.
12492 * doc/autoconf.texi (Installation Directory Variables): Update.
12493 (Limitations of Make): Some about `Single Suffix Rules and
12494 Separated Dependencies'.
12495 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12496 (ifnames, autoscan, autom4te): Un-factor into several rules.
12498 2002-09-25 Paul Eggert <eggert@twinsun.com>
12500 * BUGS (Interoperability bugs): New section. Mention libtool
12501 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12503 2002-09-24 Paul Eggert <eggert@twinsun.com>
12505 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12506 make handles suffix-rules differently from GNU make.
12508 * bin/Makefile.am (SUFFIXES, .in): Remove.
12509 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12510 Move the body of the old .in rule here.
12512 2002-09-16 Akim Demaille <akim@epita.fr>
12514 i960 compilers create `b.out' files by default.
12515 Reported by Ralf Corsepius.
12517 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12518 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12520 2002-09-13 Paul Eggert <eggert@twinsun.com>
12522 * doc/autoconf.texi (Particular Headers): Remove obsolete
12523 reference to `struct timezone' in the description of

12534 2002-09-13 Akim Demaille <akim@epita.fr>
12536 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12537 reading config.log when the compiler is rejected.
12538 Suggested by Guido Draheim.
12540 2002-09-13 Akim Demaille <akim@epita.fr>
12542 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12543 (chdir_init) might hang when stat'ing mounted directories.
12544 Reported by Vance Shipley.
12546 2002-09-12 Akim Demaille <akim@epita.fr>
12548 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12551 2002-09-12 Akim Demaille <akim@epita.fr>
12553 * doc/autoconf.texi (Defining Symbols): Present two different
12554 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12555 difference between 1 argument calls, and 2-3 argument calls.
12557 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12559 * doc/autoconf.texi: Review grammar and punctuation.
12561 2002-09-11 Paul Eggert <eggert@twinsun.com>
12563 * doc/autoconf.texi: Fix minor formatting, spelling, and
12565 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12566 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12569 2002-09-11 Akim Demaille <akim@epita.fr>
12571 * doc/autoconf.texi (Questions): Rename as...
12573 (Defining Directories): New.
12575 2002-09-09 Akim Demaille <akim@epita.fr>
12577 * doc/autoconf.texi (Making testsuite Scripts): Update.
12578 Suggested by Nishio Futoshi.
12580 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12582 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12583 plain `@' is wanted.
12585 2002-09-09 Akim Demaille <akim@epita.fr>
12587 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12588 `duplicates', since the algorithm was too naive and could keep
12589 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12590 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12591 Reported by Ralf Corsepius.
12592 * tests/torture.at (Configuring subdirectories): Exercise these
12595 2002-09-09 Akim Demaille <akim@epita.fr>
12597 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12598 looking for a replacement file.
12599 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12600 directory is relative.
12601 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12602 directory definition.
12603 Reported by Andreas Schwab and Jim Meyering.
12605 2002-09-06 Akim Demaille <akim@epita.fr>
12607 * doc/autoconf.texi (Setting Output Variables): Clarify what
12608 precious variables are.
12609 Suggested by Pontus Skoeld.
12611 2002-09-05 Akim Demaille <akim@epita.fr>
12613 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12614 (ifnames, autoscan, autom4te): Since we don't only depend on
12615 configure.ac variables (such as VERSION etc.), but also on prefix
12616 and so forth, depend on Makefile, not configure.ac.
12617 Reported by Alexandre Duret-Lutz.
12618 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12620 2002-09-05 Kevin Ryde <user42@zip.com.au>
12622 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12623 doesn't seem to be confined to ia64, just say "some versions".
12625 2002-09-04 Akim Demaille <akim@epita.fr>
12627 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12629 * Makefile.am (maintainer-clean-local): Remove.
12630 (MAINTAINERCLEANFILES): Remove COPYING.
12632 2002-09-03 Paul Eggert <eggert@twinsun.com>
12634 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12635 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12638 2002-09-03 Akim Demaille <akim@epita.fr>
12640 * configure.ac: Bump to 2.53d.
12641 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12642 as of today, on Automake's team suggestion.
12644 2002-09-03 Akim Demaille <akim@epita.fr>
12648 2002-09-02 Akim Demaille <akim@epita.fr>
12650 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12652 * configure.ac: Disable SITE_MACRO_DIR.
12654 2002-09-02 Jim Meyering <meyering@lucent.com>
12656 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12657 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12658 Also, tweak grammar: s/make sure to/be sure to/.
12660 2002-09-02 Paul Eggert <eggert@twinsun.com>
12662 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12663 directory names are generally preferable to physical names.
12665 2002-09-02 Akim Demaille <akim@epita.fr>
12667 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12668 Reported by Raja R. Harinath.
12669 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12670 * bin/autoupdate.in: Use error instead of die.
12672 2002-09-01 Paul Eggert <eggert@twinsun.com>
12674 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12675 ordinary shell concatenation rather than echo+tr+sed command that
12676 runs afoul of a long-line-related sed bug in Solaris 8.
12678 * bin/autoheader.in (parse_args): --warning -> --warnings.
12680 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12681 stdout, as traditional "ls" does.
12682 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12683 _AC_COMPILER_EXEEXT_O): Likewise.
12684 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12686 * bin/autoconf.as: Add --prepend-include option. This patch was
12687 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12688 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12690 * bin/autoconf.in, configure: Regenerate.
12692 * doc/autoconf.texi (Special Shell Variables): Mention
12693 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12695 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12696 MAILPATH and set PS1, PS2, PS4 to default values, to work
12697 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12698 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12699 the Autoconf documentation specifies; fall back to "unset" only if
12700 this fails. Use a shell for-loop for this rather than an m4 loop,
12701 to shorten the output script.
12703 2002-08-30 Paul Eggert <eggert@twinsun.com>
12705 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12706 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12707 for the CDPATH problem. Document PWD.
12708 (Limitations of Builtins): Document the problem that "cd $foo" and
12709 "ls $foo" may refer to different directories in shells conforming
12710 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12711 example, since the old example is now out of date.
12713 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12714 FOO" and "ls FOO" talk about different directories; this catches
12715 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12718 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12719 of rolling our own unset.
12720 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12721 in practice we needn't worry about CDPATH if unset doesn't work.
12723 * Makefile.in, aclocal.m4, bin/Makefile.in,
12724 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12725 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12726 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12727 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12728 tests/Makefile.in: Regenerate with Automake 1.6.3.
12730 * config/config.guess, config/config.sub, config/mkinstalldirs:
12733 * configure: Regenerate with self.
12735 2002-08-30 Kevin Ryde <user42@zip.com.au>

12745 2002-08-29 Akim Demaille <akim@epita.fr>
12747 * lib/Autom4te/General.pm (&xqx): New.
12748 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12749 hand, which is not portable.
12751 * bin/autom4te.in: Use them.
12752 Use &error instead of die.
12753 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12756 2002-08-17 Paul Eggert <eggert@twinsun.com>
12758 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12759 default list of compilers to try, since it was long ago superseded
12760 by the ksh fc builtin. Suggested by Steven G. Johnson.
12762 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12764 * doc/autoconf.texi (Invoking autom4te): End the option table,
12765 fixing a bug introduced by the previous patch.
12766 (Limitations of Make): Add a 'target lookup' subentry in the
12767 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12769 2002-07-29 Mark D. Roth <roth@feep.net>
12771 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12772 options and use $AUTOM4TE_PATH.
12773 * doc/autoconf.texi: Remove documentation of autom4te
12774 --include-envvar and --site-macro-subdir options and document
12775 use of $AUTOM4TE_PATH.
12776 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12777 arguments from each language section.
12779 2002-07-29 Paul Eggert <eggert@twinsun.com>
12781 * doc/install.texi: Include copyright symbol in copyright notice.
12783 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12785 (AM_MAKEINFOFLAGS): New macro.
12786 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12787 * Makefile.am (INSTALL): Use the new macros.
12788 Use -o rather than --output, since "missing" does not grok --output.
12790 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12792 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12793 comments do not always work. Never trust the exit status of
12796 2002-07-24 Kevin Ryde <user42@zip.com.au>
12798 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12799 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12801 2002-07-23 Paul Eggert <eggert@twinsun.com>
12803 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12804 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12805 apparently treats PATH="nonexistent" as if it contained ".".
12806 Bug reported by Stefan `Sec' Zehl.
12808 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12810 * doc/autoconf.texi (Limitations of Make): Mention the special
12811 handling of the obj/ directory by BSD make.
12813 2002-07-20 Kevin Ryde <user42@zip.com.au>

12845 Alexandre Duret-Lutz <duret_g@epita.fr>
12847 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

12853 description of the tarname default.
12855 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
12857 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
12858 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
12859 latter was not run.
12861 2002-07-17 Akim Demaille <akim@epita.fr>
12863 * lib/Autom4te/General.pm (find_file): Browse the directories in
12864 the order they are given.

13080 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13081 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13082 Both macros now accept an optional source-dir arg.
13083 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13085 * NEWS: Document this.
13086 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13088 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13089 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13090 not for GNU extensions; this undoes part of the 2000-11-03 change,
13091 reverting to 2.13-compatible behavior.

13099 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13100 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13101 and it causes a 'test' syntax error if it fails.
13102 Bug reported by Stephen Gildea.
13104 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13105 If prototypes are supported, use them to check this at compile-time,
13106 instead of trying to check it at run-time. If we must do a run-time
13107 check, assume that setvbuf is standard when cross-compiling, as
13108 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13109 Bug reported by Paul D. Smith.
13111 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13112 argument specifying location of getloadavg.c. This removes a
13113 FIXME. This idea was taken from Jim Meyering's implementation in
13115 * doc/autoconf.texi (Particular Functions): Document this.
13116 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13117 that's what the code does; this fixes a bug reported by

13122 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13123 autopoint instead of gettextize.
13124 ($uses_alocal): Rename as...
13125 ($uses_aclocal): this.
13126 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13127 Suggested by Bruno Haible.

13131 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13133 2002-04-29 Paul Eggert <eggert@twinsun.com>
13135 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13136 files to be 1 second older; just set them to be the same time.
13137 Also, sleep 1 second after the first aclocal, to work around
13138 problems with sub-second time stamps on the input files.
13140 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13142 * doc/autoconf.texi: Mention "set -e -x" lossage

13149 From Christian Cornelssen.
13151 2002-04-29 Akim Demaille <akim@epita.fr>
13153 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13154 of lack of $LINENO support, then the test will compare the $LINENO
13155 in testsuite vs. the lineno in the test file. This is wrong, of
13157 Be sure to protect it.
13158 Reported by Patrick Welche.
13160 2002-04-25 Akim Demaille <akim@epita.fr>
13162 * doc/autoconf.texi (Obsolete Macros): Typo.
13163 Reported by Vladimir Volovich.
13165 2002-04-25 Akim Demaille <akim@epita.fr>
13167 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13168 than some of the input files, hence, on the second run of aclocal,
13169 if some of its input are younger, make them older.
13170 Suggested by Paul Eggert.
13172 2002-04-25 Akim Demaille <akim@epita.fr>
13174 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

13180 and ac_subst_vars be sh variables containing the list of
13181 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13183 (_AC_INIT_PREPARE): Use them to log them.
13184 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13185 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13186 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13187 _AC_SUBST_FILES and _AC_SUBST_VARS.
13188 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13190 2002-04-24 Akim Demaille <akim@epita.fr>
13192 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13193 autoheader, so that automake does not complain about a missing
13194 config.h.in that was to be created.
13196 2002-04-23 Akim Demaille <akim@epita.fr>

13347 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13348 contains no literal separators.
13350 2002-04-03 Akim Demaille <akim@epita.fr>
13352 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13353 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13354 Use dnl, not the KILL diversion.
13356 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13357 (AC_CONFIG_LINKS): here.
13359 Don't use the KILL diversion, as it kills spurious output, which
13360 results in failures being hidden.
13361 Use m4_defn where appropriate.
13362 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13363 after the second argument.
13365 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13366 syntax, as it is provided by M4sugar.
13367 * tests/torture.at (Multiple AC_CONFIG_FILES): New.

13383 (_AC_COMPILER_OBJEXT): Use them.
13384 Fixes Debian #138666.
13386 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13388 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13390 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13391 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13392 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

13394 (AC_C_CONST): Same.

13408 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13409 to avoid versions of HP C which don't allow that.
13411 2002-03-27 Paul Eggert <eggert@twinsun.com>
13413 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

13425 2002-03-25 Paul Eggert <eggert@twinsun.com>
13427 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13428 as POSIX requires, as it doesn't work with Zsh.
13429 * doc/autoconf.texi (Assignments): Document the problem.
13431 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13433 * doc/autoconf.texi (Limitations of Make): Mention more issue
13434 about VPATH, overriding of macros in sub-makes, and handling of

13439 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13440 problem with here-document buffer boundaries.
13442 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13443 when reinvoking the shell, to work around problems with installers
13444 who put strange things like "cd" commands in their environments.

13469 (Limitations of Usual Tools): Add mkdir section.
13471 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13472 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13473 back on AS_DIRNAME to compute prefixes otherwise; this is
13474 roughly what mkinstalldirs does. That way, we need not have
13475 our own filename disassembler. The old disassembler did not
13476 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13478 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13479 Create at_test_all by a series of assignments,
13480 not by a single assignment of a long string. The latter causes ksh
13481 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13482 presumably because of a buffer overrun.
13484 2002-03-14 Paul Eggert <eggert@twinsun.com>
13486 * lib/autotest/general.m4 (at_times_skip):
13487 Renamed from at_times. Now a boolean.
13488 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13489 says 'times: not found'.

13493 * bin/autoreconf.in (&study_gettextize): New.
13494 (&autoreconf): Handle newest gettextize.

13518 2002-03-11 Andreas Schwab <schwab@suse.de>

13521 does not do it if --with-lispdir is given.

13534 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13536 2002-03-08 Akim Demaille <akim@epita.fr>
13538 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13539 aliases the actual variables, and modifications of the former
13542 2002-03-08 Akim Demaille <akim@epita.fr>
13544 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13545 because of C-c: have m4 output in tmp files, then mv them.

13568 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13569 * lib/autoconf/general.m4 (AC_INIT): More informative error
13570 message for LIBOBJ.

13579 * doc/autoconf.texi (Transforming Names): Equality between target
13580 and host is irrelevant.
13581 (Specifying Names, Canonicalizing): Remove all references to the
13582 backward compatibility hooks. Rather, collect them all into...
13583 (Hosts and Cross-Compilation): this new section.
13584 * doc/install.texi (System Type): Ditto.
13585 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13586 that `--host' implies cross-compilation.
13588 2002-03-04 Akim Demaille <akim@epita.fr>
13590 * doc/autoconf.texi (Evaluation Macros): New.
13591 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13593 (_m4_foreach): Define the variant with immediate evaluation so
13594 that it contains exactly the items, not an expression which
13595 evaluation is the current item.
13596 (m4_re_string, m4_re_word): Don't over quote them.
13598 2002-03-04 Akim Demaille <akim@epita.fr>
13600 Instead of having stacking `shift's evaluated at the end, let
13601 `foreach' loops immediately evaluate them.
13603 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13604 $*. This is the n-th time I change my mind, but hopefully this is
13607 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13609 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13610 it was only a hack for m4_text_wrap.
13611 (m4_car2): Remove, replaced by...
13613 (_m4_foreach): Adjust.
13614 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13615 m4_bpatsubst for clarification.

13706 2002-02-05 Akim Demaille <akim@epita.fr>
13708 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13732 Also, pass `--reload-state=' on them, so...
13733 (handle_m4): don't.

13735 (M4sh): Rely on M4sugar.

13773 2002-01-28 Akim Demaille <akim@epita.fr>
13775 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13776 AUTOTEST_PATH *after* it was set.
13777 Don't put `.' in the PATH: the user should be precise and `./' if
13778 needed. In addition, given that the test suite does some `cd', if
13779 `.' is in the path, the `tested programs' sections will report
13780 programs found in the test suite's directory, while during the
13781 tests (performed in their own directory), these programs are no
13782 longer visible. In other words, the results is confusing and

13860 and PACKAGE_BUGREPORT from here...
13861 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13863 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13864 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13865 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13866 * tests/tools.at (autoheader): Adjust.
13867 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13869 2002-01-06 Akim Demaille <akim@epita.fr>
13871 * bin/autoscan.in (scan_file): Use `&used'.
13873 2002-01-03 Akim Demaille <akim@epita.fr>
13875 * doc/autoconf.texi (Output): Improved wording regarding use of
13879 2001-12-18 Kevin Ryde <user42@zip.com.au>
13881 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13882 sometimes needing writable input.
13884 2001-12-17 Jim Meyering <meyering@lucent.com>
13886 * doc/autoconf.texi (New Macros): Tweak wording.
13888 2001-12-14 Akim Demaille <akim@epita.fr>
13890 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13891 trailing files, don't apply `-rf' to files which might not be
13892 created by configure (core, core.*, and *.core), but just `rm -f'.
13893 Suggested by Jonathan Kamens.
13895 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13897 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13899 2001-12-14 Akim Demaille <akim@epita.fr>
13901 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13903 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13905 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13906 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13907 abs_srcdir, top_srcpath to abs_top_srcdir.
13908 (_AC_OUTPUT_FILES): Adjust.
13909 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13910 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13911 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13913 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13915 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13916 C/Fortran linking on HP/UX, by extracting the Fortran library
13917 search path from the LPATH line in the $F77 -v output.
13919 2001-12-12 Kevin Ryde <user42@zip.com.au>
13921 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13922 forbidden file descriptors table.
13924 2001-11-26 Akim Demaille <akim@epita.fr>
13926 * bin/autoscan.in (%c_keywords): Build it at top level.
13927 Map to 1 in order to simplify its uses.
13929 2001-11-26 Akim Demaille <akim@epita.fr>
13931 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13932 Remove $filepath, useless.
13933 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13934 variables, they are really part of the tokens.
13935 Split the input line on spaces and then look for tokens.
13936 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13937 because of `lex$U.$(OBJEXT)'.
13938 (&scan_files): Use "@list" instead of join.
13939 * doc/Makefile.am (CLEANFILES): Add *.fns.
13941 2001-11-26 Akim Demaille <akim@epita.fr>
13943 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13944 Remove, replaced by...
13945 * tests/wrappl.in: Be common for all the Perl executables.
13946 In particular autoscan and autoheader want -I.
13947 * configure.ac: Adjust.
13948 * lib/autoscan/headers: errno.h is portable.
13950 2001-11-26 Akim Demaille <akim@epita.fr>
13952 * bin/autoscan.in (used): New.
13955 2001-11-26 Akim Demaille <akim@epita.fr>
13957 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13959 (&scan_sh_file): Remove a duplicate pattern.
13960 (&check_configure_ac): Use long options.
13961 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13963 2001-11-26 Akim Demaille <akim@epita.fr>
13965 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13966 Before, having a line containing the opening of a multi line
13967 comment made the whole line be ignored.
13969 2001-11-26 Akim Demaille <akim@epita.fr>
13971 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13972 (testsuite Scripts): Be one of its subsection.
13973 (Autotest Logs): New.
13975 2001-11-26 Akim Demaille <akim@epita.fr>
13977 Test groups are now run two directories deeper.
13979 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13980 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13982 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13983 top_srcdir, builddir and top_builddir.
13984 Use `at_*dir' relatively to the directory containing the
13985 suite, use `*dir' when relatively to the current group dir.
13987 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13989 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13990 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13991 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13994 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13996 * doc/autoconf.texi (Using System Type): Add an example of `case
13997 $host' usage so people quit using `case $target' everywhere.
13999 2001-11-22 Akim Demaille <akim@epita.fr>
14001 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14002 spotted by Jim Meyering.
14004 2001-11-16 Paul Eggert <eggert@twinsun.com>
14006 This patch implements a `long double' suggestion by Oliver Kiddle.
14008 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14009 static, to catch errors if the value isn't known at compile-time
14010 and the compiler supports dynamic arrays. Change its name from
14011 `_array_' to `test_array' to avoid potential name clashes.
14012 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14013 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14014 better than double. Catch a bug in GCC 2.95.2 x86.
14015 * doc/autoconf.texi (C Compiler): Document the above.
14018 2001-11-13 Akim Demaille <akim@epita.fr>
14020 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14022 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14024 2001-11-13 Akim Demaille <akim@epita.fr>
14026 * lib/autotest/general.m4 (AT_INIT): After having run the test
14027 group, go back to the initial directory, not to at_suite_dir.
14029 2001-11-13 Akim Demaille <akim@epita.fr>
14031 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14032 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14033 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14035 (AT_CHECK_CONFIGURE): Use absolute paths.
14036 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14037 The problem is still the old one: there is no means in M4 (that I
14038 know about) to create a defining macro, because there is no means
14039 to create `$1' etc., therefore, the defining macro ``swallows''
14040 all the arguments meant to the defined macro.
14042 2001-11-13 Akim Demaille <akim@epita.fr>
14044 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14045 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14047 * tests/aclocal.m4: Remove, as it is no longer used.
14049 2001-11-13 Akim Demaille <akim@epita.fr>
14051 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14052 variable names when referring to a single test group, or to
14053 `suite' when referring to the whole test suite.
14054 `at_last_test' is removed: m4 compute at_format itself.
14055 (at_stdout, at_stder1, at_stderr): New variables.
14056 (AT_CHECK): Use them.
14058 2001-11-13 Akim Demaille <akim@epita.fr>
14060 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14062 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14063 Do it as soon as a test fails, don't wait till the end of the test
14065 Don't remove $as_me.[0-9]*, since these files no longer exist.
14067 2001-11-13 Akim Demaille <akim@epita.fr>
14069 * tests/tools.at: Use absolute paths, since we are no longer run
14072 2001-11-13 Akim Demaille <akim@epita.fr>
14074 Now that tests are running in their own private dir, there is no
14075 need to list the files to remove at the end of tests groups.
14077 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14078 (AT_data_files, at_data_files): Remove.
14079 (AT_CLEANUP, AT_DATA): Simplify.
14081 Remove the group dir if !debug && !failed.
14082 * tests/atspecific.m4: Adjust.
14084 2001-11-13 Akim Demaille <akim@epita.fr>
14086 Start a new layout for Autotest: `testsuite' creates
14087 `testsuite.dir' in which the at-check-line etc. files are to be
14088 found, and `testsuite.dir/003' where the test group 3 is run.
14090 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14091 at_check_line_file, at_format, at_test_normalized, at_group_dir
14093 Create the directories.
14094 Use absolute paths for at- files.
14095 (AT_CHECK): Adjust.
14097 2001-11-11 Michael Matz <matz@kde.org>
14099 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14101 (m4_car): Properly quote arguments.
14103 2001-11-13 Akim Demaille <akim@epita.fr>
14105 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14106 with stricter rules on LIBOBJS.
14108 2001-11-12 Paul Eggert <eggert@twinsun.com>
14110 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14111 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14114 2001-11-12 Akim Demaille <akim@epita.fr>
14116 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14118 2001-11-12 Akim Demaille <akim@epita.fr>
14120 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14121 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14122 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14123 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14124 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14125 specify to what the macro should be defined (typically to 1).
14127 2001-11-12 Akim Demaille <akim@epita.fr>
14129 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14132 2001-11-12 Akim Demaille <akim@epita.fr>
14134 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14135 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14136 definition used by Automake where LEX is +/- "${missing} lex" and
14137 `missing' itself contains variables.
14139 2001-11-12 Akim Demaille <akim@epita.fr>
14141 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14142 Now that M4sh pushes BODY, the comments were output at the end of
14145 2001-11-08 Akim Demaille <akim@epita.fr>
14147 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14148 that we can trace macros from aclocal.m4.
14149 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14150 obsoleted, and redirect to the former anyway.
14151 Reported by Ralf Corsepius.
14153 2001-11-08 Akim Demaille <akim@epita.fr>
14155 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14156 processed only if present.
14157 * tests/torture.at (Configuring subdirectories): Use autoreconf
14158 instead of successive calls to autoconf.
14159 Add a nonexistent subdirectory to exercise the patch above.
14160 Reported by Ralf Corsepius.
14162 2001-11-08 Kevin Ryde <user42@zip.com.au>
14164 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14165 doesn't accept .S files.
14167 2001-11-07 Akim Demaille <akim@epita.fr>
14169 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14170 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14171 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14172 * bin/autom4te.in (warn_forbidden): New.
14173 (handle_output): Use it.
14174 Read m4_pattern_forbid with messages.
14176 2001-11-05 Akim Demaille <akim@epita.fr>
14178 * bin/autom4te.in (--normalize): Remove.
14179 * lib/autom4te.in: Adjust.
14181 2001-11-05 Akim Demaille <akim@epita.fr>
14183 * tests/Makefile.am (testsuite): Rename this target as...
14184 ($(TESTSUITE)): this.
14187 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14189 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14190 the --prefix option, also remove it's argument.
14192 2001-11-05 Akim Demaille <akim@epita.fr>
14194 * doc/autoconf.texi (testsuite Invocation): Update.
14195 (Writing testsuite.at): Update.
14197 2001-11-03 Akim Demaille <akim@epita.fr>
14199 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14201 2001-11-03 Akim Demaille <akim@epita.fr>
14203 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14204 (&file_name_is_absolute): New, wrappers around routines from
14206 Use and export them.
14207 (&find_configure_ac): Optionally take a directory where to look at.
14208 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14210 Default @ARGV to `.', not find_configure_ac.
14211 (&autoreconf): Argument is a directory.
14212 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14213 * doc/autoconf.texi (autoreconf Invocation): Update.
14215 2001-11-03 Akim Demaille <akim@epita.fr>
14217 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14218 (@export_forward_subs): New.
14219 Add basename, dirname, and fileparse.
14221 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14222 Don't look for aclocal flags if we already know aclocal is not
14224 Move aclocal.m4t only if it exists.
14225 Reported by Ezra Peisach.
14227 2001-11-03 Akim Demaille <akim@epita.fr>
14229 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14230 passed on command line, defaulting to ./configure.ac if present.
14231 (&maybe_autoreconf, File::Find): Remove, unused.
14232 (&autoreconf): If autoconf is not used, don't try to trace.
14234 2001-11-02 Akim Demaille <akim@epita.fr>
14236 * configure.ac: Bump to 2.52g.
14238 2001-11-02 Akim Demaille <akim@epita.fr>
14242 2001-11-02 Akim Demaille <akim@epita.fr>
14244 * config/config.guess, config/config.sub, doc/standards.texi:
14245 * config/lispdir.m4: Update from masters.
14246 * configure.ac: Bump to 2.52f.
14248 2001-11-02 Akim Demaille <akim@epita.fr>
14250 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14251 Don't run aclocal when aclocal.m4 is not from aclocal.
14253 Don't run libtoolize and gettextize if --install is not given.
14255 2001-11-01 Paul Eggert <eggert@twinsun.com>
14257 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14258 be invoked before _AS_LINENO_PREPARE.
14259 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14260 than character ranges.
14262 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14263 invoking AS_BASENAME. Set the locale variables to 'C' if
14264 possible, as POSIX requires this to get the traditional
14266 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14268 2001-10-31 Paul Eggert <eggert@twinsun.com>
14270 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14271 with {}, as that triggers a bug in Bash 2.05.
14273 (_AS_LINENO_PREPARE): Use Sed rather than
14274 Awk. Fix the sed prepass to work even if there are multiple
14275 instances of $LINENO on the same line. Do not substitute for
14276 other variables like $LINENOT. Do not check file dates; such a
14277 check is unreliable on sufficiently fast machines, and removing
14278 the check makes the code simpler and more reliable. Check for
14279 output and chmod failures.
14281 * doc/autoconf.texi (Special Shell Variables): Document
14284 2001-10-31 Akim Demaille <akim@epita.fr>
14286 * tests/Makefile.am (atconfig): Remove this target, Automake
14289 2001-10-31 Akim Demaille <akim@epita.fr>
14291 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14292 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14293 provided, while it is optional.
14294 * configure.ac: Adjust.
14296 2001-10-26 Paul Eggert <eggert@twinsun.com>
14298 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14299 lib/Autom4te/Struct.pm:
14300 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14303 * doc/autoconf.texi (Special Shell Variables): Document some
14304 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14306 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14307 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14308 eval $LINENO is not portable in practice.
14310 2001-10-24 Akim Demaille <akim@epita.fr>
14312 * lib/Autom4te/General.pm (backname): New.
14314 2001-10-24 Akim Demaille <akim@epita.fr>
14316 * m4/: Remove, merged into...
14319 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14321 * doc/autoconf.texi (Shellology): Mention the problems with bash
14322 2.05's use of ANSI quoting in its `set' builtin.
14324 2001-10-22 Paul Eggert <eggert@twinsun.com>
14326 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14327 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14328 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14329 POSIX decided to standardize on the int flavor of strerror_r.
14330 Always do char* test, as there's no reason not to.
14331 Assign to a char* var, to catch strerror_r that returns int*.
14333 * doc/autoconf.texi (Particular Functions):
14334 Document the above changes. Also, document the fact that
14335 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14337 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14339 2001-10-20 Akim Demaille <akim@epita.fr>
14341 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14342 the executable was missing from the log.
14344 2001-10-20 Akim Demaille <akim@epita.fr>
14346 * lib/Autom4te/General.pm (&update_file): If destination is
14347 unchanged, remove the source.
14348 (&up_to_date_p): Don't be verbose, be debug.
14349 * bin/autoreconf.in: No longer support --m4dir.

14820 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14822 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14826 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14827 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14828 be used instead of ':'.
14829 * lib/autotest/general.m4: Replace occurrences of ':' in
14830 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14832 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14834 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14835 arguments. Fixed a typo.
14837 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14839 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14840 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14842 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14844 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14846 * bin/autoheader.in: Reworded a few comments.
14847 * bin/autoconf.in: Reworded help text for a few options.

14851 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14853 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14854 already have $file). Set output files to binary mode (helps avoid
14855 CR issues on DOSish systems).
14857 2001-09-19 Akim Demaille <akim@epita.fr>
14859 * lib/autotest/general.m4: Englishoes.
14860 From Tim Van Holder and Alexey Mahotkin.
14862 2001-09-18 Paul Eggert <eggert@twinsun.com>
14864 * doc/autoconf.texi (Common Shell Constructs): New node,
14865 documenting AS_DIRNAME.
14866 (Limitations of Usual Tools): Refer to it when discussing dirname.
14867 Also, update discussion of POSIX standard to reflect latest draft.
14869 * lib/autoconf/c.m4:
14870 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14872 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14873 Do not pass a first argument with leading '-'
14874 to expr, by parenthesizing initial integers that might be negative.
14876 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14877 now merely checks whether it is an error to pass an argument
14880 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14881 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14882 whether it is a (compile-time) error to pass an argument to
14883 getpgrp. This simpler test supports the revised documentation,
14884 and is all that AC_FUNC_GETPGRP's users really need.
14886 2001-09-18 Akim Demaille <akim@epita.fr>
14888 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14896 2001-09-18 Paul Wagland <paul@wagland.net>
14898 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14900 Add test for AS_BASENAME.
14901 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14902 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14903 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14904 * tests/base.at: Fixed the expected responses. The old ones were
14906 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14907 the documentation claims it should (and how it behaved in 2.13).
14909 2001-09-18 Akim Demaille <akim@epita.fr>
14911 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14912 the AC_CONFIG_COMMANDS invocation.
14913 This also solves the name clash problems.
14914 Don't set the package's ID.
14915 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14916 No longer to be shipped.
14917 (version.in): Remove.
14918 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14919 * lib/autoconf/status.m4: Adjust.
14920 Use `m4_PACKAGE_STRING'.
14921 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14922 the only optional argument is the name of the test suite.
14923 Expect `package.m4' to define the package signature.
14924 * lib/autom4te.in (Autotest): Add `package.m4?'.
14925 * tests/Makefile.am (package.m4): New.
14926 * tests/suite.at: ifnames is a victim.
14928 2001-09-18 Akim Demaille <akim@epita.fr>
14930 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14931 AC_LIBSOURCE, AC_CONFIG_FILES.
14932 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14933 program version string doesn't match the package's.
14934 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14937 2001-09-17 Paul Eggert <eggert@twinsun.com>
14939 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14940 Allow expression to return any value that can fit into unsigned long
14941 (not int, as before). Check for output errors.
14943 2001-09-17 Bruno Haible <haible@ilog.fr>
14945 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14946 Always include <stdio.h> and <stdlib.h>. Evaluate
14947 the expression in an extra function before these includes. Call
14948 fprintf "%d" only after ensuring the argument is of type 'int'.
14949 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14951 2001-09-17 Paul Eggert <eggert@twinsun.com>
14953 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14954 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14955 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14956 when they don't exist.
14958 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14959 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14962 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14963 version with the version used by fileutils 4.1, except use
14964 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14967 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14969 2001-09-13 Akim Demaille <akim@epita.fr>

15009 * lib/autotest/general.m4 (AT_INIT): Create and remove
15010 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15011 test suites can cohabit.
15013 2001-09-13 Akim Demaille <akim@epita.fr>
15015 * tests/mktests.sh: Don't output banners for empty test files.

15124 the maintainer is dumb enough to do that...
15126 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15127 excellence in M4 quotation: consider `__file__' is active.
15129 And BTW, when invoking m4, pass the --include in the right order:

15289 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15290 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15292 Use -e, not -f, since /dev/null for instance is OK.
15293 (&parse_args): Adjust.
15294 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

15304 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

15306 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15307 find the executables for it.

15309 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15311 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15312 indeed related to running the test suite, while passing
15313 --autoconf-dir and others is related to running non installed
15314 Autoconf executables. So don't do that, leave it to...
15315 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15316 * tests/autoscan: New.
15317 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

15336 2001-08-29 Akim Demaille <akim@epita.fr>

15803 autom4te.cache (it's a directory, not a file.
15804 * Makefile.am: Ditto (but maintainer-clean-local).
15806 2001-08-15 Akim Demaille <akim@epita.fr>
15808 * bin/autom4te.in (@m4_warning): New.
15809 (&handle_m4): Use it.
15810 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

15883 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15884 * doc/autoconf.texi (C Compiler Characteristics): Update

15890 magic values from an object file when cross-compiling.
15891 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15893 2001-08-10 Akim Demaille <akim@epita.fr>
15895 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15897 Suggested by Russ Allbery.
15899 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15901 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15902 current $prefix to the sub-configures.
15904 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15906 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15907 extension (needed on BeOS). Reported by Guido van Rossum.
15909 2001-08-09 Akim Demaille <akim@epita.fr>
15911 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15913 2001-08-07 Akim Demaille <akim@epita.fr>
15915 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15917 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15918 No need to remove the files before and after the each test, before
15919 each test and at the end of the suite is enough.
15920 Display only the children `times', not the shell's.
15921 If the test failed or was skipped, at-times is not available.
15923 2001-08-07 Akim Demaille <akim@epita.fr>
15925 Always produce testsuite.log, including when there are no
15926 failures. This helps getting information on skipped tests, and
15927 duration of the tests. Err, implement the latter btw.
15929 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15930 Dump information on the first run of each test.
15931 (AT_CLEANUP): Create `at-times' containing the duration of the
15934 2001-08-07 Akim Demaille <akim@epita.fr>
15936 The use of `dumpstat' revealed that `len' was used although it
15937 should not. m4_text_wrap was using it, but in the Autoconf world
15938 where it is legal. Hence (i) test M4sh in its own world, not
15939 Autoconf's, and (ii), ahem, fix the bug :)
15941 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15942 does not like `' instead of [].
15943 (AT_INIT): Forbid `^_?AT_'.
15944 And don't output such tokens.
15945 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15946 `script.as', and `autom4te.cache'.
15947 Remove `empty' and `macro' which are no longer used.
15948 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15949 * tests/m4sugar.at: Use it.
15950 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15952 2001-08-07 Akim Demaille <akim@epita.fr>
15954 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15956 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15958 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15960 2001-08-04 Akim Demaille <akim@epita.fr>
15962 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15963 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15965 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15966 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15967 (AC_F77_MAIN): Likewise.
15969 2001-08-04 Akim Demaille <akim@epita.fr>
15971 Don't rely on M4sugar outputting the patterns in files, since we
15972 might process the output _without_ running m4, hence without these
15975 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15976 * bin/autom4te.in (@Request::includes): Remove, unused.
15977 (@Request::source): Rename as...
15978 (@Request::input): this.
15979 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15980 (&handle_output): Fetch the patterns from the traces.
15981 `$forbidden' and `$allowed' are constant: use m//o.
15982 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15983 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15985 2001-08-04 Akim Demaille <akim@epita.fr>
15987 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15988 autoconf', i.e., in addition to caching traces, cache the output.
15990 * bin/autom4te.in (Request::cache): Rename as...
15991 (Request::id): this.
15992 ($cache, $icache, $tcache, $ocache): New.
15993 (&handle_m4): Save M4 output in the cache instead of $tmp.
15994 (&handle_output): Adjust.
15995 (&up_to_date_p): Check that the output cache is up to date too.
15996 (top level): Run `&handle_m4' iff force or the cache is invalid.
15997 Run `&handle_output' if the output cache is more recent.
15999 2001-08-04 Akim Demaille <akim@epita.fr>
16001 * bin/autom4te.in ($force): New.
16002 (&parse_args, &print_usage): -f, --force is a new option.
16003 (&handle_output): CPP directives might have spaces after `#'.
16004 (&parse_args): The first file only can be frozen.
16006 2001-08-04 Akim Demaille <akim@epita.fr>
16008 Don't let autom4te compute the `include' traces several times:
16009 first check that the trace cache file is up to date, and then
16010 compare its timestamp with that of the output.
16012 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16013 the preamble. Don't require 5.005 as Autom4te::General does it,
16014 and better yet (use `use', not `require'!).
16015 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16016 Class::Struct as Autom4te::Struct.
16017 * lib/Autom4te/General.pm (File::stat): Use it.
16018 (&mtime): New, export it.
16019 * bin/autom4te.in: Use it.
16020 Declare `$req' is invalid if it is outdated.
16021 Don't declare it valid before saving it if something went wrong.
16023 2001-08-04 Akim Demaille <akim@epita.fr>
16025 Autom4te shall not encode Autoconf data, and preselecting traces
16026 must be proposed to the users.
16028 * bin/autom4te.in (@required_trace): Remove.
16030 (&parse_args, &print_usage): -p, --preselect is a new option.
16031 (&up_to_date_p): Adjust.
16032 * bin/autoconf.in: Preselect some Autoconf macros.
16034 2001-08-04 Akim Demaille <akim@epita.fr>
16036 * tests/tools.at (autoconf --trace: user macros): Check traces on
16037 macros invoked without arguments, and macros invoked with multiple

16045 2001-08-03 Akim Demaille <akim@epita.fr>
16047 * bin/autoconf.in ($@): Work around the usual sh bug.
16050 2001-08-03 Akim Demaille <akim@epita.fr>
16052 Clean up the handling of the M4 builtins tracing exception.
16054 * bin/autom4te.in (Request::request): Don't complete M4 builtins

16057 (@m4_builtin): this.
16058 (%m4_builtin_alternate_name): New.
16059 (&parse_args): Complete the trace requests with alternate names.

16065 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
16066 m4_if, and m4_wrap.
16068 2001-08-03 Akim Demaille <akim@epita.fr>
16070 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
16071 (m4_divert_pop): Dump the whole diversion stack when a diversion
16073 * bin/autom4te.in (&handle_output): Remember of the first
16074 occurrence of a possibly undefined macro, not the last.
16075 Complain about the possibly undefined macros in the same order as
16076 the appear in the output.
16077 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16078 * tests/tools.at (autoconf: forbidden tokens, basic)
16079 (autoconf: forbidden tokens, exceptions): No longer sort
16080 autoconf's stderr, as it is now deterministic.
16081 Check that `dnl' is caught.
16083 2001-08-01 Akim Demaille <akim@epita.fr>
16085 * configure.ac: Bump to 2.52c.

16102 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
16103 `END', as `Autom4te::General::END' will be triggered.
16104 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
16105 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
16106 system to run `mv', `rm', and `cmp'.
