1720 Cover more potentially problemtic file names. Use the new
1723 Properly handle funny file names for headers in config.status.
1724 The test suite did not cover this bug because the code was not
1725 quoting properly the arguments of `rm -f' (which "fails" silently)
1726 as well as the arguments of `diff' (whose output was redirected to
1727 /dev/null so we couldn't see its error message).

1845 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
1847 <DEFAULTS>: Delay computation of variables based on $at_dir...
1848 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
1849 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
1850 <PARSE_ARGS>: Parse new option.
1851 <HELP_TUNING>: Document it.

1867 * doc/autoconf.texi (Particular Programs): Do not mention the
1868 Autoconf version in which the AC_PROG_INSTALL change was done.
1869 Suggested by Paul Eggert.
1871 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1873 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1874 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1875 mode, we change to the source directory, also set $ac_pwd so we
1876 do not go back to the build tree for the next config subdir.
1877 * tests/torture.at (Deep Package): Extend test to contain two
1878 config subdirs on the top level.
1880 Fix parallel `maintainer-check'.
1881 * Makefile.am (maintainer-check-tests): Depend on `all'.
1882 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

1909 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1911 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1912 check_SCRIPTS. Building the wrappers for `all' allows help2man
1913 to use them for the manpages.
1914 Report by Benoit Sigoure.
1916 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.

1920 Fix some write failure cases in Autotest.

1932 (m4_require): Use m4_do, not m4_join.
1934 Fix some whitespace tests on cygwin.

1939 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1941 Optimize AC_REQUIRE.

1948 * tests/torture.at (srcdir): Fix quoting.

1954 * tests/base.at (Input/Output): Likewise.
1955 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1956 config.guess, and config.sub to test source tree.
1957 Drop AC_CONFIG_AUX_DIR setting.

1959 * tests/torture.at (Substitute a 2000-byte string): Drop
1960 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1961 (Substitute a newline, datarootdir workaround): Likewise.
1962 (Define a newline): Adjust for linenumber changes in configure.ac.
1963 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

1970 * tests/tools.at (Syntax of the shell scripts): Likewise.
1972 * tests/m4sh.at (LINENO): Quote $0.
1974 Fix testsuite program wrapper for whitespace in `pwd`.
1975 The problem here is that the usual mantra is that command
1976 variables can contain arguments, thus we cannot just escape
1977 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1978 $top_builddir/tests directory early in $PATH, so that the
1979 wrappers are found by their plain name.
1980 * tests/wrapper.as: Put $testdir early in $PATH.

1993 <at_func_create_debugging_script, Driver Loop>:
1994 Quote $at_group_dir.
1995 * tests/autotest.at (whitespace in absolute testdir): New test.
1997 * lib/autom4te.in: Quote @datadir@.
1999 Proper file name escaping in Autoconf programs and Perl modules.
2000 This includes escaping of characters special to the shell
2001 as well as special to Perl, e.g., leading `<' or `>'.
2002 For example, when $file starts with `>', `open ">$file"'
2003 wrongly tries to append to a different file.
2004 * bin/autoconf.as: Fix quoting for autom4te options.
2005 * lib/Autom4te/General.pm (shell_quote): New function, taken
2006 from coreutils, written by Jim Meyering.
2008 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
2010 * bin/autoreconf.in (parse_args): Likewise.
2011 * bin/autoscan.in (main): Likewise.

2014 * bin/ifnames.in: Likewise, XFile usage fixes.
2015 * tests/tools.at (autom4te and whitespace in file names): Extend
2016 test. Test twice, with special characters allowed on w32, and the
2017 rest. Test leading and trailing whitespace, for `open_quote'.
2018 (autotools and whitespace in file names): New, analogous test.
2019 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
2020 by Russ Allbery and Eric Blake.

2038 2007-12-04 Eric Blake <ebb9@byu.net>
2040 Manually resync with gnulib, since 'make cvs-update' no longer works.
2041 * build-aux/config.guess: New upstream version.
2042 * build-aux/config.sub: Likewise.
2044 When using older automake, don't downgrade build-aux/texinfo.tex.

2048 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2050 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2051 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2052 #undef as this runs afoul of our new way of creating config.h.
2053 Problem reported by Jim Meyering in
2054 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2056 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2058 Fix autom4te for unusual characters in input file names.
2059 * bin/autom4te.in (files_to_options): Quote active characters
2061 * tests/tools.at (autom4te and white space in file names):
2064 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2065 Document that Tru64 awk always splits $0.
2067 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2069 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2070 `#AT_STOP_...' line at the end of each test.
2072 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2074 * lib/autotest/general.m4 (AT_INIT): For awk line number
2075 extraction script, ensure `$at_group' has a defined value
2076 even for the empty set, and properly quote its usage inside
2079 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2081 * doc/autoconf.texi (Shell Functions): New chapter. Document
2082 IRIX sh $0 issue in functions, move content from ...
2083 (Portable Shell): ... here.
2084 (Shell Script Compiler): Note that shell functions are not
2085 totally unportable any more.
2087 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2088 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2090 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2091 extracting the line numbers of the last needed test.
2093 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2095 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2098 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2100 Fix IRIX testsuite debugging failures: $0 in functions.
2101 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2102 Do not use $0 inside a function, as IRIX sh will set that to the
2103 function name rather than the script invocation name.
2105 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2106 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2108 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2109 to extract test scripts.
2110 (AT_INIT): Extract and cache test script line numbers.
2112 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2114 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2115 subsequent fixups; the awk -> here-document conversion trashes
2116 performance too much with AIX sh.
2118 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2120 * tests/local.at: Do not test m4, perl with AT_TESTED.
2122 Diagnose and guard against write errors dealing with config.status.
2123 The general idea is this: all write failures from `configure'
2124 writing `config.status' are indicated by $ac_write_error, which
2125 is only checked at the end. This is safe because config.status
2126 code is not executed before the file is complete. Other write
2127 failures, be they inside config.status, or in sub shell/awk
2128 scripts spawned from configure or config.status, typically need
2129 earlier checking, as their results are used right afterwards.
2130 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2131 before writing config.status, check afterwards.
2132 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2133 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2134 Set `ac_write_error' for write failures to config.status. Barf
2135 upon write failures to temporary files.
2136 Adjust note about closing and reopening the here-document.
2137 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2138 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2139 reopening the here-document.
2140 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2141 Ensure `ac_write_error' does not escape into config.status.
2142 Also, add a couple of code paths not yet exercised in the test
2143 suite: a config file with input from stdin, and a config header
2145 Suggestion for catching write errors by Bruno Haible.
2147 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2149 Avoid error with Tru64 awk and testsuite lines with many words.
2150 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2151 reads the testsuite, set the field separator to an unusual value,
2152 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2153 even splits the input if $i, i>0, was never accessed in the script.
2155 Revert 2007-10-17 change.
2156 * TODO: Multiline args in config files and headers mean something
2157 different and are not fixed, see
2158 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2159 Report by Stepan Kasal.
2161 * doc/autoconf.texi (Generic Programs): Fix typo.
2163 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2165 AC_*_TOOL does not canonicalize the prefix
2166 * doc/autoconf.texi (Generic Programs): Do not say that
2167 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2169 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2171 Diagnose write errors in config.status instantiations.
2172 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2173 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2175 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2176 Extend test to also check for some write error failures, using...
2177 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2178 Report by Bruno Haible.
2181 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2183 (_AT_CHECK): Use less indentation, to save space.
2185 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2187 Add witness macro for @top_build_prefix@ substitution.
2188 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2189 (_AC_OUTPUT_FILE): Mention it here.
2191 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2192 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2194 * lib/autotest/general.m4 (at_func_test): Remove.
2195 (AT_INIT): Pre-extract test groups into separate files.
2196 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2197 Remove at-test-source files together with the $at_group_dir.
2198 * tests/autotest.at (Long test source lines): New test.
2200 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2202 Shell functions and variables may share a namespace.
2203 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2206 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2208 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2211 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2213 * lib/autoconf/status.m4: Fix a couple of comment typos.
2215 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2217 2007-11-13 Jim Meyering <meyering@redhat.com>
2219 Clean up the rule to create "expr".
2220 * tests/Makefile.am (expr): Don't redirect directly to target.
2221 Redirect just once, not for each echo statement.
2222 Use $@, not literal "expr".
2224 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2226 Don't worry about preprocessor when testing long long.
2227 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2228 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2229 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2230 These no longer check for preprocessor flaws.
2231 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2232 Do not check for preprocessor flaws.
2234 2007-11-13 Jim Meyering <meyering@redhat.com>
2236 Adapt dependencies, now that a version change doesn't modify configure.ac
2237 * GNUmakefile: Remove "make clean" kludge.
2238 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2240 Don't redirect directly to target.
2241 Use $@, not literal "version.m4".
2243 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2245 * doc/autoconf.texi (Making testsuite Scripts): Document
2246 ":;{" shorthand as in previous patch.
2248 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2250 * doc/autoconf.texi (Limitations of Builtins): Document problem
2251 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2253 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2254 Use ":;{" shorthand.
2255 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2257 2007-11-12 Jim Meyering <meyering@redhat.com>
2259 Add more non-srcdir build support.
2260 * GNUmakefile (dummy): Split a long line.
2261 Add -v option to autoreconf invocation.
2263 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2264 * GNUmakefile (dummy): Remove INSTALL.
2266 Remove racy commands to build scripts in bin/ and tests/.
2267 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2268 are guaranteed to be built, remove the rules that tried to build
2269 them. Before, with a parallel build, these rules could lead to
2270 two processes writing tests/wrapper.in concurrently.
2272 Build in man/ only *after* building in bin/ and tests/.
2273 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2274 in both bin/ and tests/.
2276 Accommodate non-srcdir build-from-checkout.
2277 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2278 Use git's --git-dir=$srcdir/.git option.
2279 Add quotes, in case tarball_version_file contains shell meta-characters.
2280 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2281 * configure.ac: Pass "." to git-version-gen.
2283 Avoid spurious test failures due to version skew.
2284 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2286 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2288 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2289 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2290 Remove conftest.dSYM directory.
2291 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2292 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2293 Remove `conftest.*' recursively.
2294 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2295 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2297 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2299 Report and analysis by Jeff Squyres and Peter O'Gorman.
2301 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2303 Fix typos in variable names.
2304 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2306 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2308 Document that $((expression)) is not portable.
2309 * doc/autoconf.texi (Shell Substitutions): Here.
2311 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2313 Ignore configure --help* errors due to LINENO-impaired shells.
2314 * tests/torture.at (Configuring subdirectories, Deep Package):
2315 In the --help* tests in read-only trees, make `.' temporarily
2316 writable again for the `stderr' file, and ignore errors due to
2317 the attempt to write configure.lineno.
2318 Report by Patrick Welche.
2320 2007-11-10 Jim Meyering <meyering@redhat.com>
2322 Generate package.m4 in build-dir, not srcdir.
2323 * tests/Makefile.am (package.m4): Adjust target.
2324 Don't redirect directly to $@.
2325 (CLEANFILES): Add package.m4.
2326 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2328 When running $(AUTOTEST), search "." before searching $(srcdir).
2330 Avoid a race condition that would make parallel "distclean" fail.
2331 * tests/Makefile.am (distclean-generic): Replace the default,
2332 automake-provided rule with an identical one, but with an additional
2333 dependency on distclean-local. Simply adding the dependency would
2334 cause automake not to emit the rule at all.
2335 * BUGS: Building with -jN works, now.
2337 Distribute git-version-gen.
2338 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2339 since GNUmakefile is distributed, and requires it for dist* rules.
2341 Remove two more generated files from version control.
2342 * INSTALL: Remove generated file.
2343 * lib/autoscan/autoscan.list: Remove generated file.
2345 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2347 * GNUmakefile (PATH): Remove stray apostrophes; they become
2348 part of PATH, which isn't wanted here.
2350 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2352 New config files output variable `top_build_prefix'.
2353 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2355 * doc/autoconf.texi (Preset Output Variables): Document it.
2357 Report by Bob Friesenhahn.
2359 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2360 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2361 function, to parametrize arithmetic with expr vs. the shell.
2362 Use it where possible.
2363 Suggestion by Benoit Sigoure.
2365 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2367 Adjust the documentation of autotest WRT atlocal.
2368 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2369 when using Automake, to write a rule to produce atlocal, since it's
2370 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2371 distributed, not atconfig.in.
2373 2007-11-04 Eric Blake <ebb9@byu.net>
2375 Update list information.
2376 * README: Mention new autoconf-commit list.
2377 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2379 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2381 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2383 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2385 * build-aux/.gitignore: Ignore mkinstalldirs.
2387 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2389 2007-11-03 Jim Meyering <meyering@redhat.com>
2391 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2392 * build-aux/git-version-gen: This syncs from coreutils.
2394 Adjust the build procedure so "make check" works reliably.
2395 * README-hacking: Include an extra step between "make" and
2396 "make check" to ensure that the latter passes.
2398 Use just-built tools, when possible.
2399 * GNUmakefile (PATH): Set and export here, ...
2400 (dummy): ... rather than here.
2402 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2403 and Andreas Schwab <schwab@suse.de>
2405 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2408 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2410 * configure.ac (AC_PREREQ): Require version 2.60, for
2411 AC_PROG_SED, AC_PROG_GREP.
2413 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2414 and Jim Meyering <meyering@redhat.com>
2415 and Andreas Schwab <schwab@suse.de>
2416 and Eric Blake <ebb9@byu.net>
2418 Document a bug in GNU Bash with compound commands and redirections.
2419 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2420 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2423 2007-11-03 Eric Blake <ebb9@byu.net>
2425 Support m4 1.4.5 in testsuite.
2426 * tests/torture.at (Define a newline): Exclude line numbers in
2428 Reported by Ralf Wildenhues.
2430 2007-11-03 Jim Meyering <meyering@redhat.com>
2432 Remove automake-provided files from version control.
2433 * build-aux/elisp-comp: Remove file.
2434 * build-aux/install-sh: Remove file.
2435 * build-aux/missing: Remove file.
2436 * build-aux/mdate-sh: Remove file.
2437 * build-aux/.gitignore: New file.
2438 Suggestion from Ralf Wildenhues.
2440 2007-11-03 Eric Blake <ebb9@byu.net>
2442 Adjust version comparison to account for git snapshot numbers.
2443 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
2444 component separator.
2445 * doc/autoconf.texi (Number processing Macros)
2446 <m4_version_compare>: Document this change.
2447 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2449 2007-10-30 Bruno Haible <bruno@clisp.org>
2451 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2452 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2453 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2454 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2455 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2456 Suggested by Paul Eggert.
2458 2007-10-28 Jim Meyering <meyering@redhat.com>
2460 * README-hacking: Autoconf, Automake, and Perl are required to build.
2461 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2463 2007-10-28 Jim Meyering <meyering@redhat.com>
2465 README-hacking: Recommend running autoreconf -vi.
2466 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2467 so that we use just-built tools when they're available.
2468 Suggestions from Ralf Wildenhues.
2470 2007-10-28 Jim Meyering <meyering@redhat.com>
2472 Make inter-release --version output more useful.
2474 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2475 which indicates that it is built using the 19th change set
2476 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2477 is a prefix of the commit SHA1.
2478 * build-aux/git-version-gen: New file.
2479 * configure.ac: Run it to set the version.
2480 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2481 * Makefile.am (dist-hook): Arrange so that .version appears only
2482 in distribution tarballs, never in a checked-out repository.
2483 * .gitignore: Add .version here, too. Just in case.
2484 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2485 not configure.ac, now that the version number changes automatically.
2487 Ensure that $(VERSION) is up to date for dist-related targets.
2488 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2489 git-version-gen doesn't match $(VERSION), but only for dist targets.
2491 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2493 Fix `Deep Package' failure with a configure script early in PATH
2494 * tests/torture.at (Deep Package): Add `.' early in PATH.
2495 Report by Jim Meyering.
2497 2007-10-27 Jim Meyering <meyering@redhat.com>
2499 Remove all generated files from version control.
2500 * aclocal.m4: Remove.
2501 * configure: Remove.
2502 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
2503 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
2504 * README-hacking: New file: how to build from just-checked-out sources.
2506 2007-10-23 Eric Blake <ebb9@byu.net>
2508 Improve corner case of m4_expand.
2509 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
2511 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
2512 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
2515 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>

3787 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3788 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3789 works but the latter doesn't, then it's a valid type.

3791 For C++ there doesn't seem to be a simple solution, so leave it alone.
3792 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3793 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

3997 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3999 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
4000 separate items of `ac_user_opts', to avoid long lines.
4001 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
4003 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4005 * doc/autoconf.texi: Fix some typos.
4007 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
4009 Fix some wording problems noted by Paolo Bonzini in:
4010 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
4011 * doc/autoconf.texi (Signed Overflow Examples): Give more
4012 discussion about the allow_superuser_privileges example,
4013 and change it a bit to make things clearer.
4014 (Optimization and Wraparound): Clarify whether the compiler
4015 will generate an infinite loop for the example derived from
4016 Autoconf's mktime test.
4017 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
4018 Also, clarify unsigned multiplication overflow.
4020 2007-01-04 Eric Blake <ebb9@byu.net>
4022 * bin/Makefile.am (RELEASE_YEAR): New macro.
4023 (edit): Use it to supply correct copyright year to scripts.
4024 * bin/autoconf.as (version): Use it.
4025 * bin/autoheader.in ($version): Likewise.
4026 * bin/autom4te.in ($version): Likewise.
4027 * bin/autoreconf.in ($version): Likewise.
4028 * bin/autoscan.in ($version): Likewise.
4029 * bin/autoupdate.in ($version): Likewise.
4030 * bin/ifnames.in ($version): Likewise.
4032 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4034 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4035 feedback. The most important changes document what happens when
4036 you convert an out-of-range value to a signed integer type, and
4037 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4040 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4041 rewrite, taking notions from the recent discussion on the gcc and
4042 autoconf mailing lists; please see
4043 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4044 and follow the many links.
4045 (Integer Overflow Basics, Signed Overflow Examples):
4046 (Optimization and Wraparound, Signed Overflow Advice):
4047 (Signed Integer Division): New sections.
4049 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4051 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4052 preprocessor macro arguments in traced name.
4053 * doc/autoconf.texi (Defining symbols): Document longstanding
4054 support for AC_DEFINE-ing macros with arguments, and document
4055 behavior when the same variable has multiple AC_DEFINEs.
4056 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4057 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4058 macros directly, giving much shorter and simpler code.
4060 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4062 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4063 space before "$ac_configure_args" to prevent a 'config.status
4064 --recheck' failure if ac_configure_args doesn't contain a leading
4065 space. This works around a problem with the XEmacs configure.ac,
4066 which uses the (undocumented) ac_configure_args variable
4067 inconsistently with Autoconf.
4069 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4071 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4072 Include <limits.h>, and use its INT_MAX to rewrite the
4073 j loop so that it does not overflow 'int'. Problem reported by
4075 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4076 Play it safe by shifting left by 1 rather than multiplying by 2,
4077 as GCC is less likely to optimize this away when the value
4078 is signed (when it assumes overflow leads to undefined behavior).
4079 Also, don't assume time_t uses two's complement.
4081 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4083 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4084 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4085 dumps core on it. Report by Tim Rice.
4087 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4089 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4090 --disable-option-checking to --help output even when
4091 AC_PRESERVE_HELP_ORDER is not used.
4092 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4093 --with argument, rather than argument with [-.] replaced by
4095 * NEWS: Fix typo in previous change; the news was in the
4098 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4100 * NEWS: Warnings are now generated by default for unknown
4101 --enable-* and --with-* options.
4102 * doc/autoconf.texi (Option Checking): Renamed from
4103 (Configure Option Checking). Tighten up the wording a bit.
4104 (External Software, Package Options): Cross-reference to Option
4105 Checking, and use this to shorten our section.
4106 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4107 "$x" to test "x$foo" != x.
4108 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4109 Don't warn if $enable_option_checking is "no".
4110 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4111 ac_unrecognized_opts to the empty string.
4112 Don't echo the unrecognized opts, as this might mishandle
4113 backslashes or leading -.
4114 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4115 usage next to the other --disable-FEATURE options in the
4118 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4120 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4121 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4122 Print warning for unrecognized --with and --enable options
4123 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4124 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4125 Disable option checking when subdirs are configured.
4126 (AC_OUTPUT): If warnings are enabled, print warning about
4127 unrecognized --with and --enable options at the end of
4128 the configure output (as well as at the beginning).
4129 * doc/autoconf.texi (Option Checking): New node.
4130 Document new option warning functionality.
4132 2006-12-16 Eric Blake <ebb9@byu.net>
4134 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4135 * NEWS: Start news for current version.
4137 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4139 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4140 Define HAVE_GETMNTENT to 1, not to the empty string.
4141 Problem originally reported by Jochen Friedrich in
4142 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4144 This change prompted by a problem report by Andrey Simonenko in
4145 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4146 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4147 object-like macros only, in the traditional portable character
4149 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4150 Warn about attempts to define things that are not identifiers.
4151 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4152 awful hack that AC_DEFINEd macro names containing parentheses.
4154 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4156 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4157 too drastic, even if Texinfo in theory requires it for info mode.
4159 (config.status Invocation): Renamed back from Recreating a
4161 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4162 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4164 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4166 * NEWS: Version 2.61a.
4168 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4169 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4171 * NEWS: Document changes with echo and printf, and the lack
4172 of limits on the total size of multi-line values of substituted
4173 variables, and the AC_FUNC_FSEEKO fix.
4175 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4177 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4178 Writing configure.ac.
4179 (Autoconf Input Layout): Renamed from configure.ac Layout.
4180 (Recreating a Configuration): Renamed from config.status Invocation.
4181 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4182 (acconfig Header): Renamed from acconfig.h.
4183 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4184 (Writing Testsuites): Renamed from Writing testsuite.at.
4185 (Autom4te Cache): Renamed from autom4te.cache.
4187 * BUGS: Remove mention of VPATH problem, since it's now documented
4188 not to be a bug in the Autoconf build procedure itself, but rather
4189 a problem with the proprietary `make' programs.
4191 * doc/autoconf.texi (Build Directories): Add a cross reference
4194 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4195 * doc/standards.texi: Sync from gnulib.
4197 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4198 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4199 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4200 generated automatically.
4202 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4204 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4205 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4206 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4208 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4210 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4211 `CEOF$ac_eof' special marker, the awk script cannot contain a
4212 line matching `^CEOF', so this is not needed any more.
4213 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4214 special marker in the test.
4216 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4218 * tests/tools.at (autom4te preselections): Use `find -newer';
4219 remove one of the sleeps.
4221 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4222 more readable, using ...
4223 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4225 * doc/autoconf.texi (autoheader Invocation): Do not double-
4226 quote the parameter of `AH_BOTTOM' in the example.
4228 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4230 * doc/autoconf.texi (Configuration Headers): Remove the
4231 example with multiple input files.
4232 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4233 multiple input files.
4235 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4237 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4238 creating the awk substitution script, handle one input line at a
4239 time, so that the maximum length of a substituted (multi-line)
4240 value is not limited by the size of the sed pattern space.
4241 The trade-off is a slightly repetitive sed script.
4242 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4243 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4244 * tests/torture.at (Substitute a 2000-byte string): Increase the
4245 test with several long lines, they should not be caught by sed
4248 * tests/tools.at (autom4te preselections): New test, to flag
4249 entries missing from autom4te.cfg.
4250 Report by David Byron <dbyron@hheld.com>.
4252 * tests/torture.at (Substitute a 2000-byte string): Actually use
4253 AC_PROG_AWK, so the last change works as intended.
4254 (Substitute and define special characters): Likewise.
4255 (Substitute a newline): Likewise.
4257 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4258 instead of `awk' consistently.
4259 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4260 * tests/torture.at (Torturing config.status): Test both the
4261 result of AC_PROG_AWK and plain awk.
4262 (Substitute a 2000-byte string): Likewise.
4263 (Substitute and define special characters): Likewise.
4264 (Substitute a newline): Likewise.
4266 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4268 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4269 can be assigned to a function pointer. Problem reported by
4270 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4271 part of a patch by Ralf Wildenhues in that same bug report.
4273 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4275 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4276 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4278 2006-12-01 Eric Blake <ebb9@byu.net>
4280 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4281 cross-compiling from cygwin to mingw.
4282 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4283 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4284 to lib/autoconf/c.m4.
4286 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4288 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4289 string for more reliable failure. Wrap the entire test that
4290 causes the broken Solaris printf to dump core, in a subshell,
4291 so the segmentation fault message is reliably suppressed.
4292 Fix shell expansion errors by using /usr/ucb/echo always;
4293 avoid an error on systems without it by another subshell.
4294 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4295 subshell-$as_echo to `as_echo', for better error message.
4297 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4299 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4300 `BASH_SOURCE' contain a newline, set them to empty, as they may
4303 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4305 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4306 years and is too hard to maintain now. The last straw was
4307 reported by Jerker Baeck in
4308 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4309 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4310 * doc/autoconf.texi (Particular Functions): Move
4311 AC_FUNC_SETVBUF_REVERSED from here...
4312 (Obsolete Macros): ... to here. Say that it does nothing now.
4313 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4314 Turn into (almost) a no-op.
4316 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4318 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4319 These macros are obsolescent and new applications shouldn't need them.
4320 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4321 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4322 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):

4324 (AC_FUNC_VPRINTF): Likewise.
4325 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4326 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4327 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4329 * doc/autoconf.texi (Setting Output Variables): Mention that
4330 @VAR1@VAR2 has unspecified behavior. Problem reported by
4332 * NEWS: Mention this.
4334 * Makefile.am: Put only a single '#' into the copyright notice,
4335 so that it's also present in the output file. Standardize wording
4336 in makefile copyright notices to match GNU coding standards.
4337 * bin/Makefile.am: Likewise.

4346 * tests/Makefile.am: Likewise.
4347 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4350 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4352 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4353 in the sed script that mangles the awk script: delete up to the
4354 first exclamation mark only.
4355 * tests/torture.at (Substitute and define special characters):
4358 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4360 Rewrite config files generation: avoid quadratic growth in
4361 the number of substituted variables by using awk instead of sed
4362 for the bulk of the substitutions.
4363 * NEWS: Mention this.
4364 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4365 forbidden in the output (and thus input) file.
4366 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4367 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4368 generate just one large awk script for substitutions,
4369 eliminating much of the earlier complexity, while adding some
4370 new complexity. Only expand the substitution templates at
4371 configure time, for smaller configure script size. If
4372 _AC_SUBST_FILES are used, test 'awk' for working getline support
4373 at config.status time. If absent, interpolate through the
4374 shell. The awk script was written with much help
4375 from Paolo Bonzini and Paul Eggert.
4376 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4377 (_AC_SED_FRAG_NUM): Likewise.
4378 (_AC_SUBST_CMDS): Renamed from...
4379 (_AC_SED_CMDS): ...this.
4380 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4381 * tests/torture.at (Substitute a 2000-byte string): Also
4382 substitute a line with 1000 words, and a variable with several
4384 (Substitute and define special characters): Test awk special
4385 characters, and put substitution input strings `@foo@' in the
4386 output, to test that no recursion happens; test several other
4387 combinations from Paolo Bonzini.
4389 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4391 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4392 that replaced echo with AS_ECHO where this wasn't necessary.
4393 Problem reportd by Ralf Wildenhues.
4394 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4395 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4396 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4398 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4400 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4402 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4404 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4405 that traditional Awk lacks 3-arg "split". It has it.
4406 Mention that FS must be a single character, and a few other
4407 99-byte limits of traditional Awk.
4408 Mention that if (i in a) doesn't work with traditional Awk.
4410 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4412 * tests/autotest.at (BSx641-newline in command):
4413 (BS-BS-newline in command, BSx640-newline in command):
4414 (Newline-CODE-BS-newline in command):
4415 (Single-quote-BS-newline in command):
4416 (Single-quote-newline-BS-newline in command):
4417 Use printf '%s\n' instead of echo, for portability to hosts
4418 where echo interprets backslashes. This will break on hosts
4419 that lack printf, but for now let's assume all such hosts
4420 are dead (if not, we should get reports of test failures).
4422 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4424 'echo' has some portability problems, when given a first argument
4425 with a leading '-', or when given any argument containing '\'.
4426 Avoid using 'echo' in these cases.
4427 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

4429 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4430 * lib/autotest/general.m4 (AT_INIT): Likewise.
4431 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4432 argument might be unportable.

4451 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4452 * bin/autoconf.as: Redo verbose flag implementation, as the old
4453 scheme wouldn't work with AS_ECHO.

4455 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

4457 * lib/autotest/general.m4 (AT_INIT): Likewise.
4458 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"

4486 * configure.ac (AC_INIT): Bump to 2.61.
4489 * tests/autotest.at (Macro with backslash in a test title):

4575 and Paul Eggert <eggert@cs.ucla.edu>

4578 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4581 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4583 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4584 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4585 Imported from a similar patch to gnulib by Bruno Haible.
4587 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

4606 and Stepan Kasal <kasal@ucw.cz>
4608 Handle special characters in test case titles correctly.

4611 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.

4616 Single-quote in a test title,
4617 Double-quote in a test title): Don't expect failure anymore.
4618 (Backslash in a test title): Put a non-whitespace character after the
4619 backslash so that Bourne shells might actually see it as an escape
4621 (Brackets in a test title,
4622 Pound in a test title,
4623 Comma in a test title,
4624 Quoted Macro in a test title,
4625 Macro in a test title,

4628 Macro with double-quote in a test title,
4629 Macro with backslash in a test title): New tests expected to fail.
4630 * tests/torture.at (#define header templates): M4-quote this title in
4631 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4632 The visible effect was a stray [] in the testsuite output.
4634 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4636 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4637 `trap ... 0' inside a function, for AIX sh.
4639 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4641 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4642 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4643 5363) simply issues a warning when dividing by zero at compile
4644 time. Problem reported by Elias Pipping.
4646 2006-10-26 Eric Blake <ebb9@byu.net>
4649 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4650 show effect on macros that expand with commas.

4675 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4677 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4678 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4679 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4680 reported by Nelson H. F. Beebe for Coreutils 6.4.
4682 * tests/tools.at (autoconf --trace: user macros): Remove test
4683 for tracing multiline macros, since m4 1.4.7a uses a different
4684 way to number lines. Problem reported by Ralf Wildenhues.
4686 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4688 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4689 /dev/null since the heuristics for interactive behaviour was

4711 * doc/autoconf.texi (Caching Results): Likewise.
4712 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4713 AC_CACHE_CHECK_INT, since it's no longer public.
4714 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4715 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4743 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4745 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4746 looking for special shell characters.
4747 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4748 macro defined by AS_VAR_PUSHDEF before passing it as a

4760 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4762 (Imported from Automake.)
4763 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4764 which incorrectly sets the mode of an existing destination
4765 directory. In some cases the unpatched install-sh could do the
4766 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4767 system. We hope this is rare in practice, but it's clearly worth
4768 fixing. Problem reported by Alex Unleashed in
4769 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4770 Also, don't bother to check for -m bugs unless we're using -m;
4771 suggested by Stepan Kasal.
4773 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4775 Import this change from Automake:
4777 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4778 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4779 is enabled by default with gnu and gnits strictness.
4780 Report from Bruno Haible.
4782 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4783 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4784 gnu and gnits modes.
4786 Import this change from Config:
4788 2006-09-20 Ben Elliston <bje@gnu.org>

4791 Import this change from Gnulib:
4793 2006-09-16 Karl Berry <karl@gnu.org>
4794 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4795 to avoid sectioning errors.
4797 Import these changes from Texinfo:

4800 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4801 (\quoteexpand): rename to \rquoteexpand.
4802 (\codequoteleft): new def, to look for @set codequotebacktick.
4803 (\lquoteexpand, \quoteexpand): new defs.
4804 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4805 (\code): must use new \...Char values, since now ` is active.
4807 2006-08-26 Karl Berry <karl@gnu.org>
4808 * build-aux/texinfo.tex (\textdegree): New command.
4810 2006-08-12 Karl Berry <karl@gnu.org>

4815 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4817 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4819 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4820 added to the template can get mangled.
4822 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4824 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4825 include the default headers, and redefine obstack_chunk_alloc
4826 and obstack_chunk_free. Fixes false failure with glibc.
4828 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4830 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4831 for backward compatibility with Libtool 1.5.22. Problem reported
4834 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4836 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require

4840 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4842 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4843 the NonStop platform.
4844 * doc/autoconf.texi (Posix Variants): Likewise.
4845 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4847 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4848 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4849 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4850 Use a better substitute, by inspecting the output of "ls"
4851 rather than just using ":".
4852 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4853 rather than AS_EXECUTABLE_P, since we needn't worry about
4854 non-regular files here.
4856 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4857 due to configuration hassles with this. See Tonya Underwood's report
4858 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4862 Stepan Kasal <kasal@ucw.cz>
4864 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4865 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4867 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4869 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4870 initialization which is not inherited through the environment
4871 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4872 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4874 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

4877 problems with mkdir -p -m.
4879 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4881 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4882 comment about ac_cpp_err; it was incorrect, and anyway
4883 ac_cpp_err is being removed below.
4884 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4885 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4886 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4888 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4889 with werror_flag and conftest.err and so forth. This is more
4890 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4891 and anyway the user shouldn't normally want to see this gorp logged.
4892 Problem reported by Ralf Wildenhues.
4893 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4894 empty, not 'no', since the rest of the code uses 'test -z'.
4896 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4898 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4899 Use a single call to AC_DO_TOKENS rather than multiple, for
4901 (_AC_LINK_IFELSE): Test that resulting file is executable.
4902 Problem reported by mwoehlke in
4903 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4905 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4906 than creating a file to use with test -x; this is much faster.
4908 2006-10-02 Bruno Haible <bruno@clisp.org>
4910 * lib/autom4te.in (Automake-preselections): Add

5364 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5365 compiler complains about it, even if things works after the
5366 complaint. Problem reported by Peter O'Gorman.
5368 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5369 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5370 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5372 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5374 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5375 after -R regardless of host. Patrick Welche reports that this
5376 fixes things on NetBSD 3.99.
5378 * NEWS: Recommend M4 1.4.5.
5380 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
5381 * tests/tools.at (autom4te cache): Update wording of diagnostic
5384 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5386 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5387 under AC_C_VOLATILE.
5388 (Volatile Objects): Be a little less skeptical about what
5389 "volatile" means. Derived from thoughts by Ben Pfaff in
5390 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5392 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5394 * doc/autoconf.texi: Fix some typos.
5396 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5398 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5399 more globally, since the 2006-06-30 patch didn't suffice. Problem
5400 reported by Keith Marshall. Also, don't bother with builddir2,
5401 since it shouldn't be needed any more.
5403 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5405 * doc/autoconf.texi (Generic compiler characteristics):
5406 Document AC_COMPUTE_INT. Fix wrong statements on Default
5407 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5409 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
5410 (_AC_COMPUTE_INT): Add obsoletion warnings.
5411 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
5414 * NEWS: Document change.
5416 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5418 * doc/autoconf.texi (Volatile Objects): New section.
5420 * NEWS: Document previous change.
5422 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5424 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5425 Require that long long int be at least 64 bits wide. C99 requires
5426 this and enough programs depend on it so we should check for it.
5427 Bruno Haible reports in
5428 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5429 that long long int is 32 bits wide with some nonstandard compilers.
5430 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5432 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5434 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5435 to a nonexistent file, so that we don't have to worry about
5436 a local site configuration that doesn't use /usr/local.
5437 Problem reported by Keith Marshall in
5438 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5440 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5442 * doc/autoconf.texi: Be more consistent about using @acronym with
5443 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5444 quite right (it talked about "OSF/Tru64", even though the
5445 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5446 and it even mentioned "OSF 4"!) and at this point there's little
5447 reason to talk about OSF any more, since it died in 1994.
5448 (Specific Compiler Characteristics): Simplify example of
5449 negative-size array.
5450 (File Descriptors): Reorder to make the text flow better.
5451 Remove joke about "appreciate the various levels"; I didn't get it.
5452 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5453 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5454 (File Descriptors, Limitations of Usual Tools):
5455 Tone down the advice against renaming or removing open files.
5456 (Limitations of Usual Tools): Add a new section, on 'rm'.
5458 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5460 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5461 -lXt in LIBS, idea from Karsten Hopp; this was due since
5464 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5465 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5466 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5467 (which belong to Xt, not X itself). See Debian bug 327655.
5469 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5471 * configure.ac (AC_INIT): Bump to 2.60a.
5474 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5478 * configure.ac, NEWS: Update.
5480 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5482 * config/texinfo.tex: Sync from upstream.
5484 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5485 quadrigraph correctly in traces.
5487 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5490 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5491 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5493 * doc/autoconf.texi (Changed Directory Variables): New node,
5494 to document the whole `datarootdir' business a bit better.
5496 * tests/torture.at (datarootdir workaround): Extend test.
5497 Prompted by report by Alexandre Julliard.
5499 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5501 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5502 when using default mode of IBM C 6 for AIX. Problem and two-line
5503 fix reported by Larry Jones.
5505 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5507 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5508 about literal '${datarootdir}' if a definition is found in the
5511 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5513 * NEWS: Use "M4" rather than "m4" when appropriate.
5514 Problem reported by Eric Blake.
5515 * doc/autoconf.texi: Likewise.
5516 Use @acronym around BSD, GCC, and GNU when appropriate.
5517 (Why GNU M4): Renamed from "Why GNU m4".
5518 (Redefined M4 Macros): Mention that Posix
5519 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5520 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5523 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5525 * bin/autom4te.in (handle_output): Do not forbid the empty
5527 * tests/tools.at (autoconf: the empty token): New test.
5529 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5531 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5532 calls, so that we do not care whether they are LIFO or FIFO;
5533 in the m4_wrap, do not check which diversion is the topmost
5534 one, just check that the stack is balanced at the end.
5535 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5536 base diversion forever--pop the previous diversion before
5537 opening the new one; consequently, remove the m4_wrap call.
5538 * lib/autotest/general.m4 (AT_INIT): Likewise.
5539 * tests/m4sugar.at: Do not use
5540 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5542 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5543 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5545 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5546 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5547 Rework example of m4wrap token-pasting trouble so that it doesn't
5548 care whether it's LIFO or FIFO.
5549 Fix some "contrary to"s that are awkward in English.
5551 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5553 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5554 to `yes' instead of `int$1_t' if the type is found, for more
5555 consistent configure output (where $1 is the number of bits).
5556 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5557 Suggested by Bruno Haible.
5559 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5560 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5561 with system headers. Report by Bruno Haible.
5563 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5565 * config/config.guess, config/config.sub: Sync from upstream.
5567 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5568 in order to avoid picking up an older installed frozen m4sh.m4f.
5569 Besides an outdated shell startup, this could have been created
5570 by an earlier M4 version with incompatible frozen file format.
5572 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5574 * README: Recommend m4 1.4.4 instead of 1.4.3..
5575 * doc/autoconf.texi: Likewise.
5576 (Special Chars in Names): Say that $(.FOO) is portable, as
5577 suggested by Stepan Kasal.
5578 (Installation Directory Variables, Build Directories):
5579 (Automatic Remaking, Subdirectories, Fortran Compiler):
5580 (Making testsuite Scripts, Defining Directories):
5581 Quote variable usages better.
5582 (Making testsuite Scripts): Add clean-local rule to makefile
5583 snippet, by Eric Blake.
5584 (Installation Directory Variables): Fix table item font.
5585 Reword slightly to clarify. Generalize advice about
5586 not using special characters to include all file-related
5587 vars, not just VPATH.
5588 (Special Chars in Variables): Warn about special characters in
5590 (Assignments): Clarify default-value example as suggested by
5592 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5593 (Special Shell Variables): Note leading ./ or ../, as suggested
5595 (Limitations of Builtins): Under cd, warn about CDPATH.
5596 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5599 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5601 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5602 `@var', for texi2html.
5603 (Systemology): Some more word wrapping, for DVI output.
5604 (autom4te Invocation): The short option for `--melt' is `-M',
5607 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5609 * doc/autoconf.texi: More formatting and English tweaks,
5610 many suggested by Ralf Wildenhues.
5611 Reword to avoid "@code{...}'s" and the like, since it's ugly
5612 with Emacs info mode. discontents -> woes.
5613 Put a few "will"s back. time stamp -> timestamp.
5614 side-effect -> side effect.
5616 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5618 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5619 Warn about $@ not persisting. Problem reported by Julien Danjou in
5620 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5621 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5622 Mention other special chars, too.
5624 2006-06-14 Eric Blake <ebb9@byu.net>
5626 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5628 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5630 * doc/autoconf.texi: Some systematic minor improvements, as
5631 follows. Use "makefile" when talking about makefiles
5632 generally (which might be named "makefile" or "Makefile" or even
5633 "foo.mk"), "Makefile" when talking about a specific makefile
5634 called "Makefile". This unclutters the text from weird quotes
5635 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5636 values" rather than "@var{foo}s" and similar constructs containing
5637 "}s". Use "Make rules" rather than "Makefile rules". Minor
5638 English-language improvements. Change the prefix "sub-" to "sub"
5640 Put blank lines around examples more consistently.
5641 Avoid "rather" and "very" as intensifiers.
5642 Avoid "will" as an auxiliary.
5643 (Limitations of Make): Split this node into....
5644 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5645 (Leading _ in Macro Names, Backslash-Newline-Newline):
5646 (Backslash-Newline Comments, Long Lines in Makefiles):
5647 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5648 (obj/ and Make, make -k Status, VPATH and Make):
5649 (VPATH and Double-colon, $< in Explicit Rules):
5650 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5651 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5652 New nodes, resulting from splitup of Limitations of Make.
5653 All cross-references changed. Raise the top node from
5654 a section to a chapter, and all subnodes accordingly.
5655 Redo the introductory wording to match the new organization.
5656 (Installation Directory Variables): Use an example that is
5657 closer to what Autoconf actually does. Mention that VPATH's
5658 value should not contain metacharacters or white space.
5659 (Fortran Compiler): Fix a VPATH bug in an example.
5660 (Leading _ in Macro Names): Mention that this problem is no longer
5661 of practical concern.
5662 (VPATH and Make): Reword the advice to make it clearer
5663 that Autoconf and Automake support VPATH in non-GNU make, but
5664 many packages have bugs in this area.
5665 ($< in Explicit Rules): Refer to Build Directories rather
5666 than using a (non-VPATH-safe) example.
5667 (Automatic Rule Rewriting): Mention the sort of disaster that
5668 can ensue with Solaris-style rule rewriting with VPATH.
5670 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5672 * doc/install.texi (Compilers and Options): Weaken the
5673 suggestion to use GNU make for VPATH builds.
5675 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5676 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5678 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5679 in regular expression.
5681 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5683 * doc/autoconf.texi (Installation Directory Variables):
5684 Drop extra @samp from `@table @samp' item.
5685 (Limitations of Usual Tools): Comment fix.
5686 Do not nest @samp just to point to other table items.
5687 (Writing testsuite.at) <AT_CHECK>: The second argument to
5688 `@dvar' is already @samp'ed.
5689 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5690 do not use @var in the second argument.
5692 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5694 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5695 $as_shell.exe too. Problem reported by Andreas Buening in
5696 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5698 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5700 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5701 `unused variable' compiler warning, for `-Wall -Werror'.
5702 Reported by Jaap Haitsma in
5703 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5705 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5707 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5708 case the compiler dumps core. Problem reported for
5709 OpenServer 5.0.7 by Tim Rice in
5710 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5711 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5714 2006-06-06 Tim Rice <tim@multitalents.net>.

5717 "ERROR" only shows up in "make check" output if there is an
5720 2006-06-06 Eric Blake <ebb9@byu.net>
5722 * tests/tools.at (automatically allowed tokens): Fix typo.

5726 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5728 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5729 typically overflows on x86 CPUs, even though the C standard
5732 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5734 * configure.ac (AC_INIT): Bump to 2.59e.
5737 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5741 * config/texinfo.tex: Sync from upstream.
5743 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5744 seen, invoke libtoolize with `--ltdl' argument.
5745 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5747 Suggested by Eric Blake.
5749 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5751 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5752 reported by Ralf Wildenhues.

5768 * tests/base.at: Check AC_REQUIRE's error message.
5769 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5771 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5773 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5774 `expout' as the last parameter.
5775 * tests/tools.at: Adapt to the above change.
5777 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5779 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5780 information about race-free implementations of mkdir.

5789 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5791 * NEWS: GNU make now recommended for VPATH builds.
5792 Mention that some macros are now documented to be obsolescent.
5793 * doc/autoconf.texi:
5794 Prefer "current" to "modern" to describe
5795 currently-used (albeit perhaps old-fashioned) hosts.
5796 Mention which ancient features no longer need to be worried about.
5797 setgid -> set-group-ID
5798 setuid -> set-user-ID (these are the Posix terms)
5799 Fix some misuses of "only".

5814 Omit longwinded and obsolescent discussion of cp -f.
5815 Modernize discussion of expr, ls.
5816 (Limitations of Make): Modernize discussion of VPATH builds.
5817 Mention $? as a workaround in some cases.
5818 * doc/install.texi (Basic Installation):
5819 Mention "./configure; make; make install" first. Be more
5820 specific about why this file is generic. Remove unnecessary
5821 parens. Remove misleading "only". Remove obsolete advice
5822 about csh. Don't say "configure" takes awhile; say it
5823 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5824 and CC=c99 rather than CC=c89, as these are blessed by current
5825 Posix. Recommend GNU make if doing a VPATH build.
5827 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5829 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for

5843 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5845 * doc/autoconf.texi (File System Conventions): Warn about ":"
5846 anywhere in directory names.
5848 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5850 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5851 about quoting the case statement, just in case.
5852 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5853 was fixed in ksh93g; reported by Ralf Wildenhues.
5855 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5857 * doc/autoconf.texi (System Services): Do not document
5858 overriding EXEEXT via ac_cv_exeext=ext.
5859 (Particular Programs) <AC_PROG_MKDIR_P>:
5860 Document that ${MKDIR_P} understands --.
5861 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5864 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5866 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5867 argument with leading hyphen. Problem reported by Paul Eggert.
5869 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5871 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5872 about quoting ac_try: quote all of it, if any of it seems suspicious.
5873 This means we don't have to worry about ${ or sed any more.
5874 Also, double-quote the case statement, to work around misuses via
5875 underquoting as reported by Ralf Wildenhues in
5876 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5877 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5878 undocumented and dangerous macro.
5879 Problem reported by Ralf Wildenhues in
5880 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5882 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5884 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5885 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5886 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5888 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5890 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5891 since evidently some packages rely on the old, broken behavior.
5892 Problem reported by Ralf Wildenhues in
5893 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5894 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5895 pre-2006-05-26 definitions, but leave in the comments that
5896 these macros are dangerous and should not be used.
5897 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5898 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5899 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5900 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5901 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5903 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5905 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5906 the use of 'tr', since this is our only use of 'tr'.
5908 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5909 and Paul Eggert <eggert@cs.ucla.edu>
5911 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5912 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5914 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5916 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5917 the output file in the `${datarootdir}' test.
5919 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5920 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5922 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5923 mention of `datarootdir' in the input file(s), but literal
5924 `${datarootdir}' in the output file, and we haven't warned yet,
5925 then warn as well: the user may have (erroneously) used
5926 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5927 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5928 * tests/torture.at (datarootdir workaround): Extend this test.
5931 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5932 and Paul Eggert <eggert@cs.ucla.edu>
5934 * doc/autoconf.texi (autoheader Invocation): The first argument to
5935 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5936 alternatives and clear up the language a bit.
5938 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5940 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5941 ac_config_guess, ac_config_sub, ac_configure.
5942 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5943 Fix typo that prevented an unnecessary space from being removed.
5944 Problems reported by Ralf Wildenhues in:
5945 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5947 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5949 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5950 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5951 Don't use the term "thread-safe" to talk about mkdir race
5952 conditions, since the problem is more a process than a thread
5953 issue. Problem reported by Stepan Kasal in:
5954 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5955 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5956 the test for 'install' more closely. Look at MKDIR_P first.
5957 Look in the PATH, and at /opt/sfw/bin.
5958 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5959 Don't bother to try mkdir -p, since we already check mkdir --version;
5960 just look at the version number. (There's no easy way to check
5961 for race-free implementations.)
5962 * tests/tools.at (autoconf: subdirectories): Adjust to above
5963 changes, since MKDIR_P now might end in "/mkdir -p".
5965 * doc/autoconf.texi (autoheader Invocation): Mention that the
5966 first arg of AC_DEFINE_UNQUOTED must be a literal.
5967 Problem reported by Ben Pfaff in
5968 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5970 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5971 * doc/autoconf.texi (Special Chars in Variables): New section.
5972 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5973 (Installation Directory Variables): Quote $(datadir) better.
5974 (Limitations of Builtins): Describe some of eval's trickiness.
5976 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5977 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5978 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5979 in front of every arg, not just trailing args. Quote apostrophes.
5980 (_AC_EVAL_ECHO): New macro.
5981 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5982 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5984 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5985 exposed by quoting of eval argument. Put the command on line line
5987 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5988 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5989 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5990 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5991 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5992 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5993 Use eval more safely.
5994 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5995 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5997 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5998 lines, exposed by quoting of eval argument.
6000 2006-05-26 Stepan Kasal <kasal@ucw.cz>
6001 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6003 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
6004 initialization of `ac_cv_exeext', do not override it if it was
6005 already set, unless it was set to `no', for compatibility with
6006 Autoconf-2.13, and comment this.
6007 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
6008 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
6009 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
6010 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
6011 Document that this test may be overridden by setting
6014 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6016 Revert these two patches:
6018 2006-04-06 Eric Blake <ebb9@byu.net>
6019 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6020 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6023 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6024 Clean up _AC_COMPILER_EXEEXT* macros.
6025 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6026 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6027 ac_file to the name of the default output file and call
6028 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6029 initial `rm' of the candidate files...
6030 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6031 the same list in subsequent `rm' calls, and for the temporary
6032 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6033 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6034 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6035 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6036 no longer needed) by libtool. Make it a cache check.
6037 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6038 copied here by mistake.
6039 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6040 _AC_COMPILER_EXEEXT.
6041 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6042 _AC_COMPILER_OBJEXT directly.
6043 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6045 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6047 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6048 Fix description of how the buggy `sed' works.
6050 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6054 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6055 ENOLCK. Only mention `make -j' when applicable. Only raise
6056 fatal errors when `make -j' is involved. Improve error message.
6058 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6060 * doc/autoconf.texi (Here-Documents): We now know more about
6061 the variable expansion in here documents bug.
6062 Thanks to Tim Rice and Stepan Kasal.
6064 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6065 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6067 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6069 * tests/autotest.at (Multiline command from M4 expansion):
6070 No failure to be expected if the shell quotes newlines in
6071 commands in the `set -x' output. Report by Tim Rice.
6074 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6076 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6077 expansion in the here-documents used by config.status, as that
6078 runs afoul of the Korn shell version M-12/28/93d bug described in
6079 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6080 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6081 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6083 2006-05-23 Jim Meyering <jim@meyering.net>
6085 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6086 Fix typo introduced with 2006-04-02 change. It reversed the sense
6089 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6091 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6092 ac_dB slightly, to save bytes in the script.
6093 Max out at 50 lines, rather than 96; this is more likely
6094 (though not guaranteed) to avoid obscure 'sed' failures.
6096 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6098 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6099 `tr -d -' as bad option argument. Work around this by deleting
6100 an unrelated character.
6101 Report by Tim Rice <tim@multitalents.net>.
6103 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6104 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6105 Stepan Kasal <kasal@ucw.cz>
6107 * doc/autoconf.texi (Particular Programs): Do not promise that
6108 we always prefer the GNU version of the program, and that we
6109 search according to PATH; both rules can have exceptions.
6110 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6111 AC_PROG_SED. Move descriptions of limitations
6112 to the Limitations of Usual Tools section.
6113 (Limitations of Usual Tools) <sed>: Mention script length
6114 limitations with Solaris /usr/ucb/sed.
6115 <grep>: Fix wording for empty alternative. Mention that -c and
6116 -l should not be combined, and that -E and -F should not be
6119 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6120 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6122 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6123 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6125 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6127 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6128 AC_DEFINE is now passed to m4_pattern_allow.
6129 * NEWS: Mention that; likewise for AC_SUBST.
6130 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6131 the parameter to m4_pattern_allow.
6132 * tests/tools.at: Add a check for that.
6134 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6136 * lib/autoconf/status.m4: Fix typos.
6138 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6140 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6141 only the files that this macro generates.
6143 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6145 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6146 the HP-UX sed limitation of 99 commands, labels do not count.
6147 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6149 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6151 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6153 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6154 Import the following fix from coreutils:
6156 2006-01-13 Jim Meyering <jim@meyering.net>
6158 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6159 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6160 not double-quote uses of that variable, to accommodate the rare
6161 case in which getmntent is available in none of the libraries
6162 checked. This happens at least on FreeBSD 5.0.
6164 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6166 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6167 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6168 some other programs unwisely rely on these undocumented vars.
6169 But put in warning comments about them.
6170 Problem reported by Ralf Wildenhues in
6171 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6172 * NEWS: Document that these variables are intended to go away.
6174 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6176 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6177 and set the language to C++ (analogous to the equivalent Fortran
6180 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6181 * doc/autoconf.texi (C++ Compiler): Document it.
6182 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6185 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6187 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6188 that caused config.status to generate 100-command sed scripts; the
6189 portable limit is 99.
6191 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6193 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6194 variable `ac_d' instead of `d' to avoid infringing namespace.
6195 Report by Ralf Menzel.
6197 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6199 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6200 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6201 * tests/tools.at (autoconf: subdirectories): New test, taken from
6202 the corresponding problem report by Ralf Wildenhues in:
6203 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6205 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6206 Quote some uses of shell variables if they might suffer unexpected
6207 globbing. This doesn't fix all instances of quoting problems that
6208 I found, just the easy ones that look safe.
6209 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6210 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6211 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6212 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6213 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6214 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6215 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6217 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6218 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6220 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6222 * bin/autoreconf.in ($help): Reword according to the manual.
6223 Suggested by Olly Betts.
6225 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6226 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6228 * bin/autoreconf.in: Pass the directory argument to
6229 `require_configure_ac'. Fix comment.
6230 * tests/torture.at (Configuring subdirectories): Expose this.
6231 Reported by Olly Betts.
6233 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6235 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6236 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6237 Automake as follows:
6239 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6240 `$configure_in' instead of `configure.in', to preserve
6241 directory component.
6243 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6245 * config/config.guess, config/config.sub, config/texinfo.tex,
6246 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6248 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6250 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6251 test for C99 conformance; (bool) 0.5 is an integer constant
6252 expression, but (bool) -0.5 is not. Problem reported by Fedor
6253 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6255 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6257 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6258 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6259 Warn about obsolete install-sh files. Remove stray sentence
6260 fragment and fix cross reference.
6261 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6262 install -d; this undoes the 2006-05-10 change.
6263 (MKDIR_P): Mark with AN_MAKEVAR.
6264 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6265 that we don't require $INSTALL to be thread-safe. Move comments
6266 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6267 of AC_PROG_INSTALL. Output a message saying that we're checking
6268 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6269 MKDIR_P instead of AC_SUBST.
6270 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6271 Special magic for MKDIR_P, too.
6272 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6274 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6276 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6278 Sync from Automake, as follows:
6280 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6281 * config/install-sh: Initialize IFS, so field splitting isn't
6283 * config/mkinstalldirs: Likewise.
6284 * config/missing: Remove superfluous quotes. Replace all uses of
6285 `[' by `test', for consistency, and for..
6286 * config/missing (sed_minuso, sed_output): New variables.
6287 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6288 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6289 Fixes `missing' to detect `--output' for help2man. Fixes
6290 PR automake/483. Report by Dennis J. Linse.
6291 (autom4te): Document in `missing --help'.
6293 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6295 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6296 * config/install-sh: Don't use 'path' to talk about file names,
6297 as per GNU coding standards. Close a race condition reported by Ralf
6298 Wildenhues and Stepan Kasal. There is still a race condition
6299 on hosts that predate Posix 1003.1-1992, but we can't help this.
6300 Don't mishandle weird characters like space on pre-Posix hosts.
6301 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6302 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6303 AC_PROG_MKDIR_P from AS_MKDIR_P.
6304 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6305 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6306 earlier editions are not (including Automake 1.8.3).
6307 Do not suggest mkinstalldirs for thread-safety.
6308 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6309 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6310 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6311 presence of special characters and race conditions.
6312 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6313 in Autoconf's name space.
6315 2006-05-10 Bruno Haible <bruno@clisp.org>
6316 and Paul Eggert <eggert@cs.ucla.edu>
6318 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6319 from Automake with minor changes.
6320 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6322 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6324 * config/install-sh: Update to Automake CVS version, as follows:
6325 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6326 * lib/install-sh: Simplify the expr implementation of dirname.
6327 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6328 * lib/install-sh: Handle --, and diagnose unknown options.
6330 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6332 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6333 `./autom4te' to create `./testsuite', since the `all' target
6334 will ensure its presence, but `installcheck' should not create
6335 the uninstalled wrappers.
6337 * tests/torture.at (Unusual Automake input files): Skip if we
6338 detect automake < 1.8.
6340 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6342 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6343 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6344 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6347 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6349 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6350 munge (multiple) white space and other oddities.
6351 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6352 single quotes in variable assignment.
6353 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6354 and similar failures by adding multiple spaces, tabs, and other
6356 Report and different test suggested by Francesco Romani
6357 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6359 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6360 single quotes, we only need to search for single quotes; this
6361 both simplifies the search pattern, and makes us less
6362 susceptible to `echo' variations for arguments not containing
6364 (_AC_ARG_VAR_VALIDATE): Likewise.
6366 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6368 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6369 `$*' and IFS concatenation issue with traditional shells and
6370 bash-2.04. Report by Seanster@Seanster.com.
6372 2006-05-03 Bruno Haible <bruno@clisp.org>
6374 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6375 precisely which Mac OS X versions have the od problem.
6377 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6379 * doc/autoconf.texi: Use @option systematically.
6381 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6382 and Bruno Haible <bruno@clisp.org>
6384 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6386 (Integer Overflow): Mention the special case of integer division
6389 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6391 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6392 traditional shells like the Solaris one that do not use the
6393 first IFS character for assembling `$*'.
6394 Prompted by a related report from autoconf_bug@nro.ca.
6396 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6397 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6399 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6400 Mention more problems with the -e option.

6405 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6407 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6408 in URLs to improve DVI formatted output (requires texinfo 4.6).
6409 (System Services, Systemology, Shellology): Likewise.
6410 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6413 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6415 (Runtime): Fix macro argument names to match description:
6416 `action-if-found' -> `action-if-true' and similarly.
6417 (Obsolete Macros): Likewise.
6418 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6419 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6420 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6422 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6424 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6427 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6430 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6432 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6433 /bin/sh set unsorted output.

6440 (Integer Overflow, Null Pointers, Buffer Overruns):
6441 (Floating Point Portability, Exiting Portably): New sections.
6442 (Writing Test Programs): Fix some langauge. Recommend exiting
6443 with status 1, not merely nonzero. Clarify exit declaration.
6444 (Run Time): Move C exit status stuff to new Exiting Portably section.
6445 (Systemology): Mention Posix and levenez. Update v7 reference.
6446 (Portable Shell): Mention the Posix shell.
6448 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6450 * bin/autoconf.as (me): Replace by as_me.
6452 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6454 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6455 since as_me isn't set yet.
6457 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6459 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6460 a few minor bugs in this area.
6462 * doc/autoconf.texi (Programming in M4sh): Comment out the
6463 documentation of AS_BASENAME, for now.
6464 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6465 (Limitations of Builtins) <basename>: Do not refer to
6467 * bin/autoconf.as (me): Don't use AS_BASENAME.
6468 (dir): Remove the unused variable.
6469 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6470 AS_DETECT_REQUIRED. All uses changed.
6471 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6473 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6474 (AS_BASENAME): Use "basename --" to protect against leading "-".

6476 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6477 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6478 (_AS_DIRNAME_PREPARE): Likewise.
6479 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6480 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6481 (AS_DIRNAME): Use "dirname --".
6483 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6485 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6486 of "run time" and "run-time" changed to "runtime", for consistency.
6487 * lib/autoconf/fortran.m4: Likewise (in comment).
6488 * lib/autoconf/functions.m4: Likewise.
6489 * lib/autoconf/general.m4: Likewise.
6490 * lib/autoconf/headers.m4: Likewise.
6492 * doc/autoconf.texi (Run Time): Document the exit status situation
6493 with more accuracy and detail.
6495 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6497 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6498 Archive is not officially `GNU' any more. Update URL.
6499 (Defining Directories): Likewise
6500 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6502 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6504 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6505 newline from the `trap' code to finish `config.log'; the NetBSD
6506 /bin/sh resets the exit status after an empty command, as
6507 documented in doc/autoconf.texi.
6508 Reported by Dalibor Topic <robilad@kaffe.org>.
6510 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6512 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6513 Suggested by Bruno Haible.
6515 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6517 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6518 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6519 Instead, just list the shells that we know work.
6520 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6521 changed. Be more cautious about the _cv_ variable.
6522 * tests/tools.at (Syntax of the shell scripts): Check the
6523 _cv_ variable once, at first, to avoid an internal autoconf error
6524 when sh -n does not work.
6526 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6528 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6530 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6532 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6533 use ">&-" since we're only 99.999% sure that this is portable,
6534 and since the MinGW bug is fixed in a different way.
6535 * lib/autotest/general.m4 (AT_INIT): Likewise.
6537 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6539 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6540 before opening config.log, to avoid hitting a bug on MinGW.
6542 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6544 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6545 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6546 This works around a MinGW bug reported by Eric Paire.
6547 Make sure that all writes to the log file append to it,
6548 rather than possibly losing data.
6549 * lib/autotest/general.m4 (AT_INIT): Likewise.
6551 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6553 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6556 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6560 * configure.ac (AC_INIT): Bump to 2.59d.
6562 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6566 * Makefile.maint (news-date-check): Do not require a leading `*'
6567 before the release date in NEWS.
6569 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6570 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6572 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6573 the instantiated file do not contain the string 'datarootdir'
6574 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6575 @mandir@, replace the reference '${datarootdir}' by the value.
6576 * tests/torture.at (datarootdir workaround): New test.
6577 * NEWS: Advertise this temporary fixup.
6578 Based on a patch by Bruno Haible, reported and analyzed by
6579 Paul Eggert and Noah Misch.
6581 2006-04-12 Eric Blake <ebb9@byu.net>
6583 * tests/autotest.at (Debugging a failed test): Fix comment.
6585 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6587 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6588 all the changes since 2006-04-07.
6590 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6592 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6593 succeeded, but `ln -s file dir' failed, take care to remove the
6594 leftover target before the next test, to prevent its spurious
6595 failure; also make sure `ln file dir' works before selecting it.
6596 Thanks to Keith Marshall for pointing this out.
6599 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6600 assignments in `at_debug_args', so that we put them correctly
6601 in the `run' script.
6602 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6603 Reported by Eric Blake.
6605 2006-04-11 Eric Blake <ebb9@byu.net>
6607 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6608 top-level tests after micro-suite has been run. Used in...
6609 (Debugging a successful test, Debugging script and environment),
6610 (Debugging a failed test): ...these new tests. The first of these
6612 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6613 macro, split out from...
6614 (AT_INIT): ...here, so that using -d also generates a run script.
6615 Document that -d inhibits top-level logging.
6616 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6617 inhibits top-level logging; debug scripts are created.
6619 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6621 * tests/autotest.at (Empty test, Empty check): New test to check it.
6623 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6626 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6628 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6629 the files if a problem appears. Make the empty *.at files
6630 read-only, too. Proposed by Ralf Wildenhues.
6632 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6634 * config/Makefile.am: Add comment to force updated Makefile.in.
6636 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6637 space only patch to this file, this patch causes the Makefile.in
6638 files that include freeze.mk to be updated, and thus have a
6639 newer time stamp again, which in turn makes a pristine CVS
6640 checkout have correct time stamps.
6642 * Makefile.maint (cvs-sv): New macro, to be used..
6643 (config.guess-url_prefix, config.sub-url_prefix)
6644 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6645 point to CVS text checkout of Gnulib files.
6646 (copyright-check): Bump current year.
6647 (announcement): Do not hard-wire `./announce-gen'.
6648 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6650 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6652 (wget_files): Update config.guess, config.sub, texinfo.tex by
6653 `wget-update', now that their URLs work again.
6655 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6657 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6658 Problem noted by Paul D. Smith.
6660 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6662 * doc/autoconf.texi: Remove unused words from word list.
6663 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6664 .x-sc_trailing_space: New files.
6666 * doc/standards.texi: Sync from gnulib.
6668 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6669 `LIBOBJDIR' as experimental.
6671 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6672 with a target directory; it's internally implemented as `cp'
6673 anyway, but since Autoconf advertises the possibility to use
6674 a target directory when LN_S is `ln -s', we need to find out.
6675 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6676 analyzed by Keith Marshall <keith.marshall@total.com>.
6680 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6682 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6683 confdefs.h as-is. In general, if it has backslash-newline or the
6684 like, then it doesn't work either to sort or to remove empty
6687 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6689 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6691 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6693 * lib/autom4te.in (Automake-preselections): Preselect
6696 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6698 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6699 apostrophe within a single-quoted string, as this is the usual
6700 tradition and is easier to read than '"'"'. Don't rely on the
6701 shell treating "$/" like '$/'. Use a more-consistent indenting
6704 2006-04-09 Eric Blake <ebb9@byu.net>
6706 * tests/autotest.at (Backquote command substitution),
6707 (Multiline backquote command substitution): Remove mistaken
6708 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6710 (Parenthetical command substitution, Multiline parenthetical
6711 command substitution): here.
6713 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6715 Import macros from gnulib (often changing their name).
6717 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6718 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
6719 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

6725 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6726 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6727 The manual mentions Gnulib more prominently.
6728 * doc/autoconf.texi (Gnulib): New node.
6729 (Pointers): Add Gnulib URL.
6730 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6731 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6733 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6734 suggest a #define rather than a typedef for _Bool, and mention
6735 Gnulib rather than trying to substitute stdbool code.
6736 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6737 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6738 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6739 AC_STRUCT_DIRENT_D_TYPE.

6844 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6846 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6847 whether `set' quotes correctly: redirect stderr of the tested
6848 `set', and use a subshell, for Ultrix; use `sed' instead of
6849 `grep' for zsh `set' which may write binary output; match only
6850 at the beginning of a line, to avoid false positives.
6851 In order to avoid false positives by unrelated variables with
6852 multiline content, put the dump algorithm in a subshell and
6853 unset all variables containing newlines (except some which are
6854 special to the shell). Warn about cache variables that are

6903 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS

7847 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7848 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7849 by the function rather than ignoring it.
7850 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7851 comparing its address. Intel's interprocedural optimization was
7852 outsmarting the old heuristic. Problem reported by

7870 Stepan Kasal <kasal@ucw.cz>
7872 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7873 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7874 make its content writable before removing it. Remove an errorneous
7875 comment from the end, where the logs of the failed tests are copied
7876 to the main log file.
7878 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7880 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

7885 problems if the testsuite were running too fast.
7887 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7889 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7890 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7891 (which belong to Xt, not X itself). See Debian bug 327655.
7892 * NEWS: Mention this.
7894 2005-09-07 Stepan Kasal <kasal@ucw.cz>

7901 suggested by Ben Elliston. Handle weird characters correctly.
7903 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7905 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7906 calls, so that the final expansion of this macro is shorter.
7907 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7908 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7909 the cleanup there. Use AS_VAR_* macros, to be more general.
7910 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7912 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7914 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7932 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7934 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7935 in the example. Reported by Bruno Haible.
7936 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7937 "if $undefined_var;" succeeds with my shell.
7939 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7940 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7941 but change the m4_divert_text to m4_divert_once.
7943 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7945 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7946 Work around bug in Solaris /usr/xpg4/bin/awk.
7947 The bug is present in at least Solaris 8 through 10.
7949 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7951 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7952 some evil values and relying on the fact that $* concatenates the
7953 parameters by the first character from IFS.

7959 first header appears, define AH_HEADER.
7960 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7961 Update limitations about when to call AC_CONFIG_HEADERS.
7962 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7963 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7964 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7965 ``Configuration Actions''; fix their index entries.
7967 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7968 options correctly. Process N-M as M-N if M is smaller than N.
7969 Process ranges correctly so that N-N will run only N.
7970 Sort and uniquify the tests that will be run. If there is more
7971 than one test, reinsert the banners for the tests.
7972 * tests/autotest.at (Keywords): Unmark XFAIL.
7974 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7976 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7977 before passing the macro name to AH_TEMPLATE.
7979 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7980 now opens log after option processing; in particular, --version
7981 and --help do not touch config.log.

7998 Prepend to LIBS, not append, in examples.
8000 2005-08-16 Stepan Kasal <kasal@ucw.cz>
8002 When building in place, set srcdir="."; suggested by Tim Van Holder.
8004 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
8005 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
8006 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
8007 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
8008 does not mean "no --srcdir option".
8010 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8012 * tests/autoscan.at (autoscan): New file.
8013 * tests/suite.at: Use it.

8021 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8022 add "2>&1"; gzip 1.2.4 prints help on stderr.
8024 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8026 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8027 was pushdef'ed twice while popped only once. Push it only once.
8028 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8030 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8032 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

8037 * Makefile.maint: Update from Bison.
8039 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8040 "<tab>" in comment, so that the point is understandable.
8042 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8044 Rewrite substantial part of lib/autoconf/status.m4.
8045 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8046 and CONFIG_COMMANDS are not processed in four separate loops.
8047 Instead, there is one main loop. This alows that the common code
8048 is expanded only once, thus config.status (and configure) is smaller.
8050 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8051 the AC_LIST_FILES and cousins macros are no longer used.
8053 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8054 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8055 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8056 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8057 contain the initialization, nor the for loop, nor the associated
8058 commands; all these go to ...
8059 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8060 _AC_OUTPUT_CONFIG_STATUS.
8061 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8062 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8063 (_AC_OUTPUT_FILE): The creation of the sed script ...
8064 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8065 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8066 _AC_OUTPUT_MAIN_LOOP.
8067 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8068 _AC_CONFIG_COMMANDS): Use ...
8069 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8070 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8071 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8072 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8073 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8074 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8076 (_AC_CONFIG_UNIQUE): Update.
8077 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8078 Replaced by this ...
8079 (_AC_LIST_TAGS): ... new common macro.
8080 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8081 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8082 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8083 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8084 this didn't belong to the `config commands' section.
8085 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8086 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8087 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8088 to the `config commands' section either.
8089 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8090 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8092 ... and many changes to the comments nearby.
8094 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8095 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8096 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8097 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8098 (#define header templates): The comment at the top of the generated
8099 header now includes the name(s) of the source file(s).
8101 Several unrelated small changes:
8103 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8104 parameter to AC_DIAGNOSE.
8105 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8106 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8107 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8108 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8110 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8111 in AC_OUTPUT doesn't double-quote it either.
8112 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8115 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8117 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8118 versions of Portland Group compiler produce single- and double-quoted
8119 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8120 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8122 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8124 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8125 This is a corrected version of yesterday's patch.
8127 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8129 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8130 path, too; insert a "===" to emphasize the line.
8132 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8133 ac_cv_build_alias to ac_build_alias.
8134 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8136 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8137 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8138 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8139 (AC_ARG_VAR): ... here.
8140 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8143 Keep a list of all precious variables and process them with one simple
8144 for loop, instead of expanding all commands, or, OTOH, complicated
8145 processing of output of "set".
8146 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8147 variable names in new macro...
8148 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.

8207 configure_input, top_builddir, srcdir, etc.
8208 * lib/autotest/general.m4 (AT_INIT): Likewise, for

8272 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8273 the directory specific variables; but don't call it for configure_input.

8277 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8280 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8282 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

8300 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8301 variable into diagnostic. Make the diagnostic an error, not a warning,
8302 because we really don't support spaces and suchlike in dir names.
8303 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8304 Don't worry about backslashes in srcdir; it can't happen now.

8333 (Special Shell Variables): Fix sed code this in the example.
8334 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8335 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

8348 * doc/autoconf.texi:
8349 Don't mention Solaris versions so much, if a
8350 problem is common to all extant versions of Solaris. Say "SunOS
8351 4" instead of "SunOS" for SunOS 4.
8352 (awk): Mention more of the limitations of traditional Awk.

8395 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8396 -u, since it outputs chatter if the input files are the same.
8397 Problem reported by Ralf Menzel.
8399 2005-06-08 Derek Price <derek@ximbiot.com>
8401 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8402 renaming them since they are about to be redefined anyhow.
8404 2005-06-08 Derek Price <derek@ximbiot.com>
8406 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8407 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8408 Move m4_undefine to alphabetical order.

8413 * doc/autoconf.texi (Introduction): Likewise.
8414 Reword to avoid some formatting glitches.
8415 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

8417 Redo example output tp match current CVS snapshot.
8418 Use @example.org in email addresses when the examples
8419 might get inadvertently cut-and-pasted into user code.
8420 Remove example of autom4te usage that doesn't seem to work now.
8421 Use modern AC_INIT (except when the example is meant to be
8422 shown with Autoconf 2.13).
8423 Update ksh info for Solaris 9 and later.
8425 Modernize description of Automake versions a bit.
8426 Don't claim a future version of Autoconf is near.

8436 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8437 Tru64 ksh pattern matching bug. Reported against Libtool by
8438 Albert Chin <libtool@mlists.thewrittenword.com> and
8439 Nicolas Joly <njoly@pasteur.fr>.
8441 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8443 m4_cdr of one-member list was [[]] (one-member list containing an
8444 empty string) instead of [] (an empty list. Callers were skewed to
8445 match this misbehaviour. As a consequence of this:
8446 - m4_foreach([x], [], [foo]) expanded to `foo', while
8447 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8448 This bug has been fixed:
8450 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8451 expand to an empty string; print error msg if called without
8453 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8454 misbehaviour; handle [] and [[]] correctly.

8464 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8465 swallow records with more than 99 fields.
8466 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8467 parse the long line.
8469 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8471 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8472 swallow literals longer than 399. Reported by Ralf Wildenhues.

8484 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

8506 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may

8511 commands can be put in a sed script portably.

8561 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8562 (ac_top_builddir): ... this ...

8581 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8582 argument to m4_foreach. I guess it was necessary in the past,

8666 * doc/autoconf.texi (Autoconf Language): Be more precise about
8667 quoting rules. Problems noted by Stepan Kasal.
8668 Also, throughout this document, be more careful about white space.
8669 "blank", "white space", and "space" all have different meanings
8670 and we should be careful to say what we mean.

8681 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8683 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8685 * doc/autoconf.texi (Generic Functions): Typos.
8687 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8689 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8690 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8691 set by latest automake.
8693 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8695 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"

8706 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8709 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8710 by AC_DEFINE; it was a mistake.
8711 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8713 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8715 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8717 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8719 * doc/autoconf.texi (External Software): Quadrigraphs are not
8720 processed correctly in AS_HELP_STRING; avoid this in the examples.
8721 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8722 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8723 comment and reduce m4_default([foo], []) to [foo].
8724 (m4_strip): Update the explanation.
8726 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8728 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8729 Remove core.conftest.* too; it's generated by Tru64 5.1.
8730 Problem reported by Jennis Pruett.
8731 * lib/autoconf/functions.m4
8732 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8733 Don't bother to remove core files; AC_RUN_IFELSE should do that
8736 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8738 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8755 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8757 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8758 as well as configure.in. Problem reported by Gregorio Guidi.
8760 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8762 * doc/autoconf.texi (Particular Functions): Use gnulib's current

8778 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8780 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8781 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8782 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8783 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8784 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8786 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8788 * NEWS: The configure command now warns you if you attempt to use
8789 a directory whose name contains a special character like space,
8791 * doc/autoconf.texi (Installation Directory Variables): Allow
8792 "," in file names. Do not use \@; it's not a portable regexp.
8793 * bin/Makefile.am (edit): Likewise.
8794 * lib/Makefile.am (edit): Likewise.
8795 * tests/Makefile.am (edit): Likewise.
8796 * tests/semantics.at: Likewise.
8797 * tests/torture.at: Likewise.
8798 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8799 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8800 * doc/autoconf.texi (File System Conventions): Warn about
8801 unportable file names.
8802 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8804 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8805 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8806 ac_pwd, and quote srcdir.
8807 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8809 * doc/autoconf.texi: Fix some systematic formatting problems.
8810 ".)" needs a following @: if not at the end of a sentence, and
8811 similarly for "!)". "etc." should be preceded by a comma.
8812 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8814 2005-03-22 Bruno Haible <bruno@clisp.org>
8816 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8817 argument is often called 'build-aux'.
8819 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8821 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8822 macro AC_TRY_LINK is obsolete.
8823 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8826 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8828 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8829 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8830 from a Common Lisp's `cl'.
8831 (AC_PROG_CXX): Behave according to the documentation: don't
8832 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8833 make the variable CCC precious; use `cl.exe', not `cl'.
8835 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8836 Alexandre Duret-Lutz <adl@gnu.org>
8838 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8839 /dev/null, as "configure" shouldn't read stdin, and this insulates
8840 us from problems (e.g., when testing for "cl"). Also, do this
8841 redirection before invoking "hostname" or "uname", and keep the
8842 original input stream available via...
8843 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8844 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8845 bother with "</dev/null" since it's now done at the top of
8847 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8848 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8849 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

8854 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8856 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8857 newline if neither \c nor -n work, as that would output two
8858 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8860 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8862 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8863 This causes that any required macros inside will get before the if.
8864 * doc/autoconf.texi (autom4te.cache): A typo.
8866 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8868 Undo previous change, except keep the change to
8869 lib/autoconf/programs.m4 that replaced grep with shell
8870 pattern-matching. This is because net-snmp configure reads stdin.
8871 Reported by Noah Misch.
8873 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8875 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8876 from /dev/null, as "configure" shouldn't read stdin, and this
8877 insulates us from problems (e.g., when testing for "cl").
8878 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8879 before invoking "hostname" or "uname".
8880 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8881 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8882 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8883 "</dev/null" since it's now done at the top of 'configure'.
8884 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8885 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8886 Also, replace grep with shell pattern-matching, to save a process.
8888 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8890 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8891 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8892 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8895 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8897 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8898 grep -q isn't portable. Improve grep -s explanation.
8899 Problem reported by Dan Manthey.
8901 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8903 * doc/autoconf.texi (Special Shell Variables): Clarify
8904 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8906 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8908 * doc/autoconf.texi: Use @acronym for DJGPP.
8909 Fix some @code's that should have been @env's, and vice versa.
8910 Sort environment variable names.
8911 Mention that shells no longer inherit IFS.
8912 Don't recommend PATH_SEPARATOR=';' so strongly.
8913 Mention that $RANDOM might expand to the empty string.
8914 "symlink" and "soft link" -> "symbolic link".
8915 Improve mktemp description (reported by Bruno Haible).
8917 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8919 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8920 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8922 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8925 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8927 * NEWS: Mention AT_COPYRIGHT.
8929 * tests/local.at (AT_CMP): Use diff directly on input files rather
8932 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8933 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8935 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8936 and Paul Eggert <eggert@cs.ucla.edu>
8938 * tests/autotest.at (Empty test suite): New test.
8939 * tests/torture.at (Substitute and define special characters)
8940 (Substitute a 2000-byte string, Define to a 2000-byte string)
8941 (Substitute a newline, Define a newline): New tests.
8943 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8945 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8946 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8947 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8948 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8949 (Standard regular expressions): New test.
8950 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8951 excess test name quoting.
8952 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8953 CPPFLAGS to `configure' instead of setting it in `configure'.
8955 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8956 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8959 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8960 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

8965 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8966 (AT_CONFIG_CMP): New macro.
8967 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8968 * tests/c.at (Extensions): Do not exit early.
8969 * tests/atlocal.in: Inherit $GREP.
8971 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8972 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8974 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8975 (AC_COPYRIGHT): Factor header comment portion out and move into...

8988 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8990 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8991 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8993 Try not to generated lines of unlimited length, as POSIX places a
8994 2047-byte limit on line length of portable text files.
8995 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8996 Use newline as a separator, not space.

9005 are restored after function return.
9007 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
9009 * doc/autoconf.texi (Special Shell Variables): Mention _,
9010 BIN_SH, DUALCASE. Say that variables other than "status" are safe
9011 if they contain a lower-case letter. The DUALCASE problem was
9012 reported by Ralf Wildenhues.
9014 * bin/autoconf.as: Don't exit with status 0 after write failure
9015 with --help or --version.
9016 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

9021 * doc/autoconf.texi (Limitations of Usual Tools):
9022 Unicos 9 sed limitations.
9023 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
9024 to get the option-enhanced interface on older Crays. Try ftn for
9025 Fortran 95 (newer Crays).
9027 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
9029 * man/Makefile.am (.x.1): Go back to the simple solution, but take
9030 care to echo the commands, so the user knows what's going on.
9031 Modified from a suggestion by Stepan Kasal.
9033 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
9034 with a cross reference. Derived from a suggestion by Bruce Korb.
9036 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
9038 * doc/autoconf.texi (config.status Invocation): Warn about
9039 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
9040 * doc/install.texi (Defining Variables): Likewise.
9041 Based on a proposed patch by Ralf Wildenhues.
9043 * man/Makefile.am (.x.1): Make sure the required generated files
9044 are up to date. Problem and original solution proposed by Stepan Kasal.
9045 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
9046 implicit-man-prerequisites): New rules, used by the above.

9054 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9055 Update the long comment explaining it.
9057 m4_require no longer writes an ``is required by'' line to the
9058 execution stack. It contains only one bit of non-redundant
9059 information: that the macro was required, not called. And even
9060 this bit is useless in most situations: have you ever met a macro
9061 which both calls and requires the same macro?
9063 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9064 (_m4_defun_pro_outer): ... only via this macro, for the outermost

9069 execution stack; slightly improve the out-of-a-defun error message.
9070 (_m4_divert_grow): New macro, counter for the temporary diversions.
9071 (_m4_require_call): Use it.
9072 * tests/m4sugar.at (m4_require): Expect output without the
9073 ``is required by'' messages.
9075 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

9169 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
9170 stored in _m4_divert_diversion or _m4_divert_dump.
9171 (m4_divert_pop): When the parameter is given, compare the symbolic
9172 name with the last diversion pushed on the stack. Previously, the
9173 current diversion was compared with the numeric value of the
9174 diversion given as the parameter.
9175 (m4_require): If the macro hasn't been expanded yet, call ...
9176 (_m4_require_call): this new macro.

9481 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
9483 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9484 "char c = '\200';" rather than "char c = 0x80;" as the
9485 latter doesn't conform to the strict C standard due to
9486 overflow on signed char hosts.
9488 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
9489 to -qlanglvl=ansi. We don't want to disable extensions.
9491 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>

9549 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9550 the $1_found variable, don't test whether the file is executable;

9587 * doc/autoconf.texi (auindex): New macro.
9588 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.

9597 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9598 readable; it's not true in OS/2-emx.
9600 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9602 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9603 "/usr/include", clear ac_x_includes instead of leaving it as "no"

9634 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9635 texinfo.tex for now (done by hand now).
9636 * Makefile.maint (wget_files, cvs_files):
9637 Remove ansi2knr.c; nobody uses it.
9638 (ansi2knr.c-url_prefix): Remove.
9639 (cvs-update): Fix test for failure. I don't know why it ever
9642 * doc/autoconf.texi: Update URLs, some of which went stale.
9643 Use @uref rather than @href.
9645 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9646 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9648 * config/config.guess, config/config.sub, config/elisp-comp,
9649 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9650 doc/fdl.texi, doc/standards.texi: Sync with master copy.

9661 to be consistent with the terminology of the GNU coding standards.

9665 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9666 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9667 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9668 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9670 More fixes to support spaces in the name of the build directory.
9671 This isn't a complete fix but it's an improvement.
9673 * bin/autoconf.as (autom4te_options): New var.
9674 Use it instead of appending to AUTOM4TE, so that we can allow
9675 spaces in the build directory's absolute name.
9676 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9677 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9678 AT_CHECK_NOESCAPE): Likewise.
9679 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

9691 and isnan. From a suggestion by Kevin Ryde.
9693 * lib/Autom4te/General.pm (END): Return correct exit status even
9694 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9696 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9698 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9699 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9700 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9702 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9704 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9705 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9706 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9707 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9708 * lib/autom4te.in (Automake-preselections): Preselect
9709 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9711 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9713 * lib/autom4te.in (Automake-preselections): Preselect
9714 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

9727 with pdksh, too. Problem reported by Patrick Welche via
9729 * doc/autoconf.texi (Shellology): Note that set -o posix is
9730 useful for pkdsh, too.
9732 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9734 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9735 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9736 Don't fail if ENV or BASH_ENV is readonly.
9737 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9738 etc. are read only. Problem reported by Ludovic Courtes.
9740 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9742 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9743 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9746 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9748 * doc/autoconf.texi (File System Conventions): Warn about
9749 names like "aux". Problem reported by Eric Blake.
9751 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9752 by zero instead of array size, so that we can use any arithmetic
9753 constant expression (instead of requiring an integer constant
9754 expression). This allows us to test expressions like DBL_MAX <
9755 LDBL_MAX, which didn't conform to the C standard using the old
9757 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9758 now that we can do floating-point tests at compile time.
9760 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9762 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9763 and LDBL_EPSILON, as the resulting expression isn't an
9764 integer constant expression and violates the C standard.
9765 Problem reported by Nelson H. F. Beebe. Also, check
9766 for "L" suffix, and check that long double doesn't have
9767 worse range or precision than double, that mixed-mode
9768 arithmetic doesn't generate a diagnostic, that double
9769 constants fit in long double.
9771 2004-06-03 Kevin Ryde <user42@zip.com.au>
9773 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9774 malloc(0) and realloc(NULL,size).
9776 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9779 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9781 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9782 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9785 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9787 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9788 can be rewritten using if-then-else. Suggested by Bruno Haible.
9790 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9792 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9793 Problem reported by Stepan Kasal.
9795 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9797 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9798 change). Patch reported by Ralf Wildenhues in
9799 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9801 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9802 function F exists if the compiler and linker let you compile an
9803 expression like (F != 0). Recent versions of GCC optimize away
9804 the reference to F in that case, since every function address must
9805 be nonzero, so the link succeeds even if F does not exist.
9806 Problem reported by Manu in
9807 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.

9822 referencing AC_FUNC_STRERROR_R.
9824 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9825 note pessimistic assumption when cross compiling.
9827 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9829 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9830 (until 2004) invoked subcommands with sh -e, contra POSIX.
9831 Reported by Kevin Ryde.
9833 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9835 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9836 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9837 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9838 `test -f " /usr/bin/grep"', which _always_ failed.
9839 (AC_PROG_SED): Ditto bogus PATH fix.
9840 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9841 requires that grep correctly supports _multiple_ `-e' options, rather
9842 than stating only that grep should accept `-e'.
9844 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9846 Port to C99, which requires that 'exit' be declared.
9848 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9849 to ensure that stdlib.h is included.
9850 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9851 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9852 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9853 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9854 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9855 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9856 when using 'exit' in a test; C99 requires that 'exit' be declared.
9858 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9860 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9861 now prefers 'grep' implementations that accept -e.
9862 (Limitations of Usual Tools): Describe problems of traditional
9863 egrep and fgrep with long input lines, and of traditional grep
9865 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9866 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9867 All callers changed. Append /usr/xpg4/bin to the PATH, for
9869 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9870 the user with complaints about multiple -e options.
9871 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9872 Define it with AC_PROG_GREP.
9873 * configure.ac (AC_PROG_GREP): Add.
9874 * lib/freeze.mk (GREP): New macro.
9876 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9878 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9879 a possible candidate only after all others fail, rather than
9880 consulting it first. This improves backward compatibility by
9881 better reflecting the way shell selection occurred in previous
9882 versions of Autoconf, and should help to avoid triggering latent
9883 problems in other packages, such as the one in Automake where zsh
9884 is not handled robustly:
9885 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9886 Although it is not Autoconf's responsibility to work around
9887 problems in Automake, it nevertheless makes sense to avoid
9888 introducing unnecessary incompatibilites.
9890 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9891 Gary V. Vaughan <gary@gnu.org>
9893 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9894 how deeply nested we are when a suitable tool is found, set the
9895 ac_path_TOOL_found flag.
9896 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9897 nested we are in this macro. Break out of all 3 nested loops if
9898 ac_path_TOOL_found is set.
9900 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9902 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9903 of the _AS_PATH_WALK loop too if GNU flavor is found.
9905 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9907 * doc/autoconf.texi (Limitations of Make): Update documentation
9908 for `$<'. New entry `Long lines', based on a report from Simon
9909 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9910 paragraph about DJGPP, based on a mail from Richard Dawe.
9912 2004-04-20 Paul Eggert <eggert@twinsun.com>
9914 * tests/c.at (C keywords): Don't assume that GCC supports
9915 "restrict" and "inline", as sufficiently-old GCC versions do not
9916 (also, GCC configured to be in pedantic C89 mode does not).
9917 Problem reported by Sumit Pandya in:
9918 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9920 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9921 consider -g to work if it generates warnings when plain compiles
9922 don't. Problem reported by Braden McDaniel in:
9923 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

9926 reported by Jim Meyering in:
9927 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9929 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9930 linker output files before linking, to work around IRIX 6 linker bug.
9931 Problem reported by Rainer Orth in:
9932 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9934 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9936 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9937 best tool so far counter rely on the tool path variable name to
9938 avoid checks for one tool being affected by the results of running
9939 the length check on a previous tool.
9941 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9942 match expression argument, as different greps have different
9943 regular expression flavours.
9944 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9946 (AC_PROG_EGREP): Pass 'EGREP$'.
9947 (AC_PROG_GREP): Pass 'GREP$'.
9949 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9951 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9952 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9954 2004-03-29 Paul Eggert <eggert@twinsun.com>
9956 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9957 Types, Specific Compiler Characteristics, System Services,
9958 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9959 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9960 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9961 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

9975 now defines HAVE_DECL_TZNAME if it is declared, when
9976 HAVE_STRUCT_TM_TM_ZONE is not defined.
9977 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9978 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

10025 behavioral changes.
10026 * tests/mktests.sh: Do not generate tests for the
10028 * NEWS: Document these changes.
10030 * doc/autoconf.texi: Avoid macros with unbraced arguments,

10047 * bin/Makefile.am (edit): Don't use $< in a context where
10048 POSIX doesn't require support for it. Use $@.in instead.
10049 Problem reported by Anthony N. Frasso in
10050 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

10066 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10067 problem on QNX reported by Stephen Rasku in

10070 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10071 $(m4sh_m4f_dependencies); this removes a FIXME.
10072 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10073 (MAINTAINERCLEANFILES): Split into pieces,
10074 one per related section. Add $(srcdir)/wrapper.in.

10079 AC_SUBST provides no portable way to escape literal newlines.
10081 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10082 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10083 Darwin uses -lcrt2.o and there's little point to cataloging all
10084 the system variants. Partial fix reported by Andreas Waechter in:

10110 Paul Eggert <eggert@twinsun.com>
10112 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
10113 (AS_INIT): Output shell initialization there. Removed optional
10114 parameter. Expand _AS_SHELL_FN_SPY.

10127 trigger the bash bug anymore.
10128 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10129 use AS_INIT_WITH_SHELL_FN.
10130 * bin/autoconf.in, tests/wrapper.in: Regenerated.
10132 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

10160 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

10162 the 2003-05-22 change, which removed the older years from the list.
10163 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

10174 egrep and fgrep respectively if $GREP -E/-F don't work.
10175 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10176 _AC_PROG_GREP, and AC_PROG_SED.
10177 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10178 longest input length accepted by a command.

10207 2004-01-26 Paul Eggert <eggert@twinsun.com>
10209 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10210 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10211 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10212 not <inttypes.h>. Problem reported by Tim Mooney in
10213 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10214 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10217 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10218 otherwise "make check" fails because it forbids cmp (I guess
10219 because cmp treats files as binary on DOS-like systems).
10221 * tests/mktests.sh: Update copyright date to 2004, since some tests
10222 have changed in 2004.
10224 2004-01-23 Gary V. Vaughan <gary@gnu.org>

10227 non-truncating sed or gsed program in PATH.
10228 * tests/acprograms.at: Add it.

10232 2004-01-15 Paul Eggert <eggert@twinsun.com>
10234 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10235 -std1 disables some useful extensions on Tru64. Problem reported
10236 by N. Lichtmaier in
10237 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10239 2004-01-14 Paul Eggert <eggert@twinsun.com>
10241 * doc/autoconf.texi (Programming in M4sh): Document that
10242 AS_MKDIR_P succeeds if the destination is a symbolic link
10243 to an existing directory.
10244 (Limitations of Usual Tools): Note that mkdir -p might not
10245 succeed on symlinks to directories.
10247 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10249 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10250 * bin/autoheader.in: Grammar fix in message.
10251 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10252 Test for dir before calling mkdir -p. (trivial changes)

10259 2004-01-10 Jim Meyering <jim@meyering.net>
10261 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10263 2004-01-09 Paul Eggert <eggert@twinsun.com>
10265 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10266 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10267 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10268 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10269 AC_COMPILE_IFELSE, since we now assume our caller invokes
10270 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10271 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10272 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10273 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10275 2004-01-07 Paul Eggert <eggert@twinsun.com>
10277 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10278 `"'...'"`, as it's confusing (and I suspect it may not work on
10279 some platforms). The code was incorrect anyway, as it assumed
10280 that \$ evaluated to itself in that context. Reported by
10281 Alexandre Duret-Lutz.
10283 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10285 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10286 and _LT_AC_TAGCONFIG.
10288 2004-01-06 Paul Eggert <eggert@twinsun.com>
10290 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10291 example, and add more examples. Reported by Eric Sunshine.

10313 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10314 Use "rm -f" to remove conftest.sed, not plain "rm".
10315 Bug reported by David Relson in
10316 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10318 * Makefile.am (autom4te-update):
10319 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

10335 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10336 -c -o might not work. From a suggestion by Kevin Ryde.
10337 (C Compiler, Generating Sources, Limitations
10338 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10339 Don't put '-o' after non-options, as POSIX doesn't allow this.
10340 Mention that cc's name might be gcc or c89 or whatever.
10342 2004-01-04 Kevin Ryde <user42@zip.com.au>

10353 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10354 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

10356 explanation clearer.

10367 * tests/atlocal.in: Store the result here.
10368 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

10370 of explicitly testing.
10371 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10372 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10373 * tests/tools.at (Syntax of the shell scripts): Simplify

10458 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10459 than $target since the latter is not usual, add guidelines on when to

10641 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10642 -mGLOB_options_string stuff for Intel ifc, which can cause

10667 cache variable instead of $G77 to decide whether to include -O2,
10668 since $G77 is specific to Fortran 77.

10678 arguments so that it can be used with syntax identical to
10679 AC_PROG_F77, and so that we can more easily decide to
10680 remove/deprecate the DIALECT optional argument in the future if it
10681 proves troublesome.
10682 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10683 non-freeform-supporting compilers. Document freeform flags.
10685 2003-10-03 Akim Demaille <akim@epita.fr>

10748 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10749 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

10754 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10755 directory for AC_CONFIG_COMMANDS' first argument exists.
10756 This makes valid the invocation of _AC_SRCPATH that follows.
10757 Reported by Eric Sunshine.

10781 The test suite are sometimes assigning timings incorrectly.
10782 Reported by Henk Krus.
10783 Diagnosed by Nicolas Joly.
10785 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10787 Instead of making AT_help a sequence of assignments to grow
10788 $at_help_all, just make AT_help_all be the growing contents of
10789 $at_help_all, and make a single assignment in...
10791 (at_times_skip): Flip the meaning and rename as...
10792 (at_times_p): this.

10803 (ifnames): chmod -w.
10804 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10805 executables, not bin/ executables! Otherwise all the magic needed
10806 to find non installed files is turned off. This caused a failure
10807 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10808 as found in its environment (sent by tests/autoreconf): pointing
10809 to bin/autom4te that could not find its files.
10810 * tests/mktests.sh: Force the replacement of generated files, for
10811 the sake of "mv" program that are interactive when overwriting a

10864 and AC_FC_FREEFORM.

10906 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10908 Add support for newer Fortran dialects. The F77 interface is
10909 unchanged, and continues to support Fortran 77. New FC macros
10910 correspond to all the old F77 macros, with output variables FC,

11014 * bin/autom4te.in: Adjust to output the call stack.

11040 2003-08-21 Akim Demaille <akim@epita.fr>
11042 First stab at preserving warnings between calls to autom4te,
11043 including when the cache is used.
11045 There are still several issues: (i) there are too many runs of m4
11046 (one for include, one for warnings, and some more), (ii) warnings
11047 spreading on several lines are not handled gracefully, (iii) the
11048 code meant to have the call stack display for errors does not work
11049 (its handling should move from m4 to autom4te).
11051 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11053 (@preselect): Add m4_warn.
11054 ($exit_status): Remove, use $exit_code.
11055 ($help): Use Autom4te::ChannelDefs::usage.
11056 (&handle_m4): No longer define the m4_warnings.
11057 At each run, extract and report the warnings.
11058 Always cache the result, including if the exit status is on
11059 failure, since if nothing changes, we should result in the same
11060 failure, hence we can use the cache.
11061 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11062 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11064 (m4_warn): Redefine as a do-nothing: it is its invocation that
11065 matters, as warnings are now reported via traces.
11066 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11067 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11068 the latter reveals calls to the former.
11072 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

11094 (&catfile): Remove.
11095 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
11096 * bin/autoscan.in: Adjust.
11098 2003-08-20 Akim Demaille <akim@epita.fr>
11100 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
11101 Reported by Alexandre Duret-Lutz.
11103 2003-08-20 Akim Demaille <akim@epita.fr>
11105 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11106 * bin/autom4te: Adjust.
11107 In particular, be Autoconf tools are really silent when properly
11108 working, bind the verbosity of the 'note' channel to $verbose.
11109 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11110 (&xsystem, &contents): Remove, since they are exported by...
11111 * lib/Autom4te/FileUtils.pm: this.

11114 * lib/Autom4te/FileUtils.pm: here.

11231 2003-06-23 Akim Demaille <akim@epita.fr>
11233 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11234 not all of them. This fixes 1. the fact that when testing
11235 Autoconf there are many many config.log, 2. the incorrect use of
11236 top_srcdir to find config.log.
11237 Don't mix the detailed output of failed test with the summary of
11238 failures. Rather, append detailed log afterwards.
11240 2003-06-23 Akim Demaille <akim@epita.fr>
11242 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

11330 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11331 63 for version mismatches.
11333 2003-05-23 Akim Demaille <akim@epita.fr>
11335 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of

11355 Paul Eggert <eggert@twinsun.com>
11357 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11358 Remove `#include <stdlib.h>' from the list; we should never
11359 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11360 resulting namespace pollution would cause other tests to fail.
11361 Configure scripts run with some older versions of g++ and HP's
11362 aCC would fail due to such an #include. Problems reported by
11363 Matthew Mueller in <http://bugs.debian.org/120704> and by
11365 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11366 In the test, use the test declaration before including <stdlib.h>,
11367 as that's closer to how it'll be used.

11371 * doc/autoconf.texi (Header Portability): ucred.h.
11374 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11376 Overhaul Autotest's logging: generate separate log files
11377 in testsuite.dir/NNN/testsuite.log, and append them to
11378 testsuite.log instead of re-running the test verbosely.
11380 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11381 file descriptor, write 0 to at_status_file instead of setting
11382 at_status=0, initialize some new variables (at_status_file,
11383 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11384 to rerun the tests, instead append the at_group_log to the

11520 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11521 by aclocal.m4 is changed it might require the importing of another
11522 m4 extension file, i.e., aclocal must be run.

11795 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11796 defined, to support freestanding compilers. This should fix the
11797 bug reported by Momchil Velkov in

11800 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

11836 * Makefile.maint: Sync with Bison, i.e.:
11837 (po-check): Scan .l and .y files instead of the

11900 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11902 We _have_ to stop using the old compatibility scheme that tried to
11903 avoid useless backslashes because Libtool 1.4.3 contains a
11904 AC_DEFINE([error_t], [int],
11905 [Define to a type to use for \`error_t' if it is not
11906 otherwise available.])
11907 We _have_ to quote the single quote and backslashes with \. The
11908 old compatibility scheme saw that ` was backslashed, and therefore
11909 did not quote the single quote. Hence before this patch, Autoconf
11910 was not compatible with Libtool.

12301 Reported by Alexandre Duret-Lutz.
12303 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12308 (&up_to_date): If a file that was included according to the cache

12323 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report

12360 From Sam Varshavchik.
12362 2002-10-08 Akim Demaille <akim@epita.fr>
12364 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12365 aclocal invocation, as Gettext macros might not be visible to

12373 Work around problems found when POSIXLY_CORRECT=1 is set.
12374 None of this seems to have anything to do with POSIX, really,
12375 but it's how Perl getopt works.
12376 * bin/autom4te.in (parse_args): Configure GetOpt with
12378 * doc/autoconf.texi (Invoking autom4te):
12379 --warning -> --warnings.
12380 * lib/autom4te.in: --warning -> --warnings.
12382 2002-09-28 Akim Demaille <akim@epita.fr>
12384 * doc/autoconf.texi (autom4te.cache): New section.
12386 2002-09-28 Akim Demaille <akim@epita.fr>

12396 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12397 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12399 2002-09-28 Akim Demaille <akim@epita.fr>
12401 * tests/torture.at (Configuring subdirectories): Be robust to
12402 users who use config.site to require for a cache: in this case,
12403 the two last configure runs, using two different sets of
12404 arguments, trigger a legitimate error.
12406 2002-09-28 Akim Demaille <akim@epita.fr>
12408 * tests/m4sh.at (Functions Support, Functions and return Support):
12411 2002-09-28 Akim Demaille <akim@epita.fr>
12413 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12414 autoheader are Perl programs.
12415 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12416 (autom4te): Specify that the sources are in the $srcdir.

12424 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12425 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12426 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

12439 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12440 (.m4.m4f): Don't pass --prepend-include, since that's done by
12441 tests/autom4te itself.
12442 * lib/autoscan/Makefile.am: Include freeze.mk.
12443 (autoscan.list): New target --this file is no longer a source.
12444 (autoscan.pre): New file.
12446 2002-09-28 Akim Demaille <akim@epita.fr>
12448 * bin/autoscan.in (@kinds): Make them singular.
12450 (&init_tables): When --debug, report the list of rules to ease
12451 tracking changes in autoscan.list.
12452 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12454 2002-09-28 Akim Demaille <akim@epita.fr>
12456 * lib/autoscan/functions, lib/autoscan/headers,
12457 * lib/autoscan/identifiers, lib/autoscan/makevars,
12458 * lib/autoscan/programs: Merge into...
12459 * lib/autoscan/autoscan.list: this.
12460 * bin/autoscan.in (&init_tables): Adjust.
12462 2002-09-28 Akim Demaille <akim@epita.fr>
12464 * lib/autoscan/functions, lib/autoscan/headers,
12465 * lib/autoscan/identifiers, lib/autoscan/makevars,
12466 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12467 `functions' line is now prefixed with `function:'.
12468 * bin/autoscan.in (&init_tables): Adjust.
12470 2002-09-28 Akim Demaille <akim@epita.fr>
12472 From now on, autoscan files must always map a macro name to a
12473 word: there is no `default' macro for autoscan.
12475 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12477 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12480 2002-09-28 Akim Demaille <akim@epita.fr>
12482 * bin/autoscan.in (%c_keywords): Remove.
12483 (&used): Keep only track of the words we might be interested in.
12484 (&output_kind): It is no longer needed to look for non active
12487 2002-09-27 Akim Demaille <akim@epita.fr>
12489 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

12491 * lib/autoscan/functions: Adjust.
12492 * doc/autoconf.texi (Particular Functions): Adjust.
12494 2002-09-27 Akim Demaille <akim@epita.fr>

12498 Thanks to Bill Moseley and Paul Eggert.
12499 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12500 the tmpdir must be created.
12501 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12502 dir be in the build tree, instead of $TMPDIR.
12504 2002-09-27 Akim Demaille <akim@epita.fr>
12506 * bin/autoscan.in: Improve the comments.
12507 (&parse_args): Drop obsolete undocumented options.

12514 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12515 Reported by Ralf Corsepius.
12516 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12518 2002-09-26 Akim Demaille <akim@epita.fr>
12520 Single suffix rules and seperated dependencies are not portable.
12522 * doc/autoconf.texi (Installation Directory Variables): Update.
12523 (Limitations of Make): Some about `Single Suffix Rules and
12524 Separated Dependencies'.
12525 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12526 (ifnames, autoscan, autom4te): Un-factor into several rules.
12528 2002-09-25 Paul Eggert <eggert@twinsun.com>
12530 * BUGS (Interoperability bugs): New section. Mention libtool
12531 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12533 2002-09-24 Paul Eggert <eggert@twinsun.com>
12535 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12536 make handles suffix-rules differently from GNU make.
12538 * bin/Makefile.am (SUFFIXES, .in): Remove.
12539 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12540 Move the body of the old .in rule here.
12542 2002-09-16 Akim Demaille <akim@epita.fr>
12544 i960 compilers create `b.out' files by default.
12545 Reported by Ralf Corsepius.
12547 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12548 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12550 2002-09-13 Paul Eggert <eggert@twinsun.com>
12552 * doc/autoconf.texi (Particular Headers): Remove obsolete
12553 reference to `struct timezone' in the description of
12556 2002-09-13 Akim Demaille <akim@epita.fr>
12560 * config/config.sub, config/config.guess: Update.
12561 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12562 * Makefile.am: Adjust.
12564 2002-09-13 Akim Demaille <akim@epita.fr>
12566 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12567 reading config.log when the compiler is rejected.
12568 Suggested by Guido Draheim.
12570 2002-09-13 Akim Demaille <akim@epita.fr>
12572 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12573 (chdir_init) might hang when stat'ing mounted directories.
12574 Reported by Vance Shipley.
12576 2002-09-12 Akim Demaille <akim@epita.fr>
12578 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12581 2002-09-12 Akim Demaille <akim@epita.fr>
12583 * doc/autoconf.texi (Defining Symbols): Present two different
12584 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12585 difference between 1 argument calls, and 2-3 argument calls.
12587 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12589 * doc/autoconf.texi: Review grammar and punctuation.
12591 2002-09-11 Paul Eggert <eggert@twinsun.com>
12593 * doc/autoconf.texi: Fix minor formatting, spelling, and
12595 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12596 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12599 2002-09-11 Akim Demaille <akim@epita.fr>
12601 * doc/autoconf.texi (Questions): Rename as...
12603 (Defining Directories): New.
12605 2002-09-09 Akim Demaille <akim@epita.fr>
12607 * doc/autoconf.texi (Making testsuite Scripts): Update.
12608 Suggested by Nishio Futoshi.
12610 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12612 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12613 plain `@' is wanted.
12615 2002-09-09 Akim Demaille <akim@epita.fr>
12617 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12618 `duplicates', since the algorithm was too naive and could keep
12619 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12620 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12621 Reported by Ralf Corsepius.
12622 * tests/torture.at (Configuring subdirectories): Exercise these
12625 2002-09-09 Akim Demaille <akim@epita.fr>
12627 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12628 looking for a replacement file.
12629 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12630 directory is relative.
12631 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12632 directory definition.
12633 Reported by Andreas Schwab and Jim Meyering.
12635 2002-09-06 Akim Demaille <akim@epita.fr>
12637 * doc/autoconf.texi (Setting Output Variables): Clarify what
12638 precious variables are.
12639 Suggested by Pontus Skoeld.
12641 2002-09-05 Akim Demaille <akim@epita.fr>
12643 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12644 (ifnames, autoscan, autom4te): Since we don't only depend on
12645 configure.ac variables (such as VERSION etc.), but also on prefix
12646 and so forth, depend on Makefile, not configure.ac.
12647 Reported by Alexandre Duret-Lutz.
12648 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12650 2002-09-05 Kevin Ryde <user42@zip.com.au>
12652 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12653 doesn't seem to be confined to ia64, just say "some versions".
12655 2002-09-04 Akim Demaille <akim@epita.fr>
12657 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12659 * Makefile.am (maintainer-clean-local): Remove.
12660 (MAINTAINERCLEANFILES): Remove COPYING.
12662 2002-09-03 Paul Eggert <eggert@twinsun.com>
12664 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12665 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12668 2002-09-03 Akim Demaille <akim@epita.fr>
12670 * configure.ac: Bump to 2.53d.
12671 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12672 as of today, on Automake's team suggestion.
12674 2002-09-03 Akim Demaille <akim@epita.fr>
12678 2002-09-02 Akim Demaille <akim@epita.fr>
12680 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12682 * configure.ac: Disable SITE_MACRO_DIR.
12684 2002-09-02 Jim Meyering <meyering@lucent.com>
12686 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12687 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12688 Also, tweak grammar: s/make sure to/be sure to/.
12690 2002-09-02 Paul Eggert <eggert@twinsun.com>
12692 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12693 directory names are generally preferable to physical names.
12695 2002-09-02 Akim Demaille <akim@epita.fr>
12697 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12698 Reported by Raja R. Harinath.
12699 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12700 * bin/autoupdate.in: Use error instead of die.
12702 2002-09-01 Paul Eggert <eggert@twinsun.com>
12704 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12705 ordinary shell concatenation rather than echo+tr+sed command that
12706 runs afoul of a long-line-related sed bug in Solaris 8.
12708 * bin/autoheader.in (parse_args): --warning -> --warnings.
12710 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12711 stdout, as traditional "ls" does.
12712 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12713 _AC_COMPILER_EXEEXT_O): Likewise.
12714 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12716 * bin/autoconf.as: Add --prepend-include option. This patch was
12717 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12718 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12720 * bin/autoconf.in, configure: Regenerate.
12722 * doc/autoconf.texi (Special Shell Variables): Mention
12723 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12725 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12726 MAILPATH and set PS1, PS2, PS4 to default values, to work
12727 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12728 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12729 the Autoconf documentation specifies; fall back to "unset" only if
12730 this fails. Use a shell for-loop for this rather than an m4 loop,
12731 to shorten the output script.
12733 2002-08-30 Paul Eggert <eggert@twinsun.com>
12735 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12736 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12737 for the CDPATH problem. Document PWD.
12738 (Limitations of Builtins): Document the problem that "cd $foo" and
12739 "ls $foo" may refer to different directories in shells conforming
12740 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12741 example, since the old example is now out of date.
12743 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12744 FOO" and "ls FOO" talk about different directories; this catches
12745 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12748 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12749 of rolling our own unset.
12750 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12751 in practice we needn't worry about CDPATH if unset doesn't work.
12753 * Makefile.in, aclocal.m4, bin/Makefile.in,
12754 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12755 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12756 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12757 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12758 tests/Makefile.in: Regenerate with Automake 1.6.3.
12760 * config/config.guess, config/config.sub, config/mkinstalldirs:
12763 * configure: Regenerate with self.
12765 2002-08-30 Kevin Ryde <user42@zip.com.au>
12767 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12770 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12772 * bin/autom4te.in (Request::load): Correctly test for "do" read
12775 2002-08-29 Akim Demaille <akim@epita.fr>
12777 * lib/Autom4te/General.pm (&xqx): New.
12778 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12779 hand, which is not portable.
12781 * bin/autom4te.in: Use them.
12782 Use &error instead of die.
12783 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12786 2002-08-17 Paul Eggert <eggert@twinsun.com>
12788 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12789 default list of compilers to try, since it was long ago superseded
12790 by the ksh fc builtin. Suggested by Steven G. Johnson.
12792 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12794 * doc/autoconf.texi (Invoking autom4te): End the option table,
12795 fixing a bug introduced by the previous patch.
12796 (Limitations of Make): Add a 'target lookup' subentry in the
12797 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12799 2002-07-29 Mark D. Roth <roth@feep.net>
12801 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12802 options and use $AUTOM4TE_PATH.
12803 * doc/autoconf.texi: Remove documentation of autom4te
12804 --include-envvar and --site-macro-subdir options and document
12805 use of $AUTOM4TE_PATH.
12806 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12807 arguments from each language section.
12809 2002-07-29 Paul Eggert <eggert@twinsun.com>
12811 * doc/install.texi: Include copyright symbol in copyright notice.
12813 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12815 (AM_MAKEINFOFLAGS): New macro.
12816 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12817 * Makefile.am (INSTALL): Use the new macros.
12818 Use -o rather than --output, since "missing" does not grok --output.
12820 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12822 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12823 comments do not always work. Never trust the exit status of
12826 2002-07-24 Kevin Ryde <user42@zip.com.au>
12828 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12829 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12831 2002-07-23 Paul Eggert <eggert@twinsun.com>
12833 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12834 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12835 apparently treats PATH="nonexistent" as if it contained ".".
12836 Bug reported by Stefan `Sec' Zehl.
12838 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12840 * doc/autoconf.texi (Limitations of Make): Mention the special
12841 handling of the obj/ directory by BSD make.
12843 2002-07-20 Kevin Ryde <user42@zip.com.au>
12845 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
12848 2002-07-19 Akim Demaille <akim@epita.fr>
12850 * doc/autoconf.texi (Function Portability): `exit'.

12861 2002-07-18 Akim Demaille <akim@epita.fr>
12863 * config/config.guess, config/config.sub: Update.
12865 2002-07-18 Akim Demaille <akim@epita.fr>
12867 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

13106 This improves on an earlier suggestion by H. Peter Anvin.
13108 2002-05-16 Paul Eggert <eggert@twinsun.com>
13110 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13111 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13112 Both macros now accept an optional source-dir arg.
13113 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13115 * NEWS: Document this.
13116 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13118 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13119 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13120 not for GNU extensions; this undoes part of the 2000-11-03 change,
13121 reverting to 2.13-compatible behavior.

13129 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13130 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13131 and it causes a 'test' syntax error if it fails.
13132 Bug reported by Stephen Gildea.
13134 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13135 If prototypes are supported, use them to check this at compile-time,
13136 instead of trying to check it at run-time. If we must do a run-time
13137 check, assume that setvbuf is standard when cross-compiling, as
13138 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13139 Bug reported by Paul D. Smith.
13141 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13142 argument specifying location of getloadavg.c. This removes a
13143 FIXME. This idea was taken from Jim Meyering's implementation in
13145 * doc/autoconf.texi (Particular Functions): Document this.
13146 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13147 that's what the code does; this fixes a bug reported by

13152 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13153 autopoint instead of gettextize.
13154 ($uses_alocal): Rename as...
13155 ($uses_aclocal): this.
13156 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13157 Suggested by Bruno Haible.
13159 2002-05-03 Akim Demaille <akim@epita.fr>
13161 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13163 2002-04-29 Paul Eggert <eggert@twinsun.com>
13165 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13166 files to be 1 second older; just set them to be the same time.
13167 Also, sleep 1 second after the first aclocal, to work around
13168 problems with sub-second time stamps on the input files.
13170 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13172 * doc/autoconf.texi: Mention "set -e -x" lossage
13173 under node "Limitations of Builtins".

13179 From Christian Cornelssen.
13181 2002-04-29 Akim Demaille <akim@epita.fr>
13183 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13184 of lack of $LINENO support, then the test will compare the $LINENO
13185 in testsuite vs. the lineno in the test file. This is wrong, of
13187 Be sure to protect it.
13188 Reported by Patrick Welche.
13190 2002-04-25 Akim Demaille <akim@epita.fr>
13192 * doc/autoconf.texi (Obsolete Macros): Typo.
13193 Reported by Vladimir Volovich.
13195 2002-04-25 Akim Demaille <akim@epita.fr>
13197 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13198 than some of the input files, hence, on the second run of aclocal,
13199 if some of its input are younger, make them older.
13200 Suggested by Paul Eggert.
13202 2002-04-25 Akim Demaille <akim@epita.fr>
13204 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

13210 and ac_subst_vars be sh variables containing the list of
13211 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13213 (_AC_INIT_PREPARE): Use them to log them.
13214 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13215 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13216 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13217 _AC_SUBST_FILES and _AC_SUBST_VARS.
13218 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13220 2002-04-24 Akim Demaille <akim@epita.fr>
13222 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13223 autoheader, so that automake does not complain about a missing
13224 config.h.in that was to be created.
13226 2002-04-23 Akim Demaille <akim@epita.fr>

13347 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13348 on Autotest and M4sh.
13349 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13350 (wrapsh.in): New target.
13351 * bin/autoconf.as: New, precursor of autoconf.in.
13352 (autoconf.in): New target.
13354 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

13357 with indented comments in rules.

13373 Reported by Ezra Peisach.
13375 2002-04-04 Andreas Schwab <schwab@suse.de>
13377 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13378 contains no literal separators.
13380 2002-04-03 Akim Demaille <akim@epita.fr>
13382 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13383 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13384 Use dnl, not the KILL diversion.
13386 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13387 (AC_CONFIG_LINKS): here.
13389 Don't use the KILL diversion, as it kills spurious output, which
13390 results in failures being hidden.
13391 Use m4_defn where appropriate.
13392 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13393 after the second argument.
13395 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13396 syntax, as it is provided by M4sugar.
13397 * tests/torture.at (Multiple AC_CONFIG_FILES): New.

13402 expanded if $# <= 2.

13413 (_AC_COMPILER_OBJEXT): Use them.
13414 Fixes Debian #138666.
13416 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13418 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13420 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13421 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13422 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13423 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13424 (AC_C_CONST): Same.

13438 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13439 to avoid versions of HP C which don't allow that.
13441 2002-03-27 Paul Eggert <eggert@twinsun.com>
13443 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13444 (AS_SHELL_SANITIZE): Invoke it.

13451 2002-03-26 Akim Demaille <akim@epita.fr>
13453 * doc/autoconf.texi (Introduction): The GNATS base moved.
13455 2002-03-25 Paul Eggert <eggert@twinsun.com>
13457 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13458 as POSIX requires, as it doesn't work with Zsh.
13459 * doc/autoconf.texi (Assignments): Document the problem.
13461 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13463 * doc/autoconf.texi (Limitations of Make): Mention more issue
13464 about VPATH, overriding of macros in sub-makes, and handling of
13467 2002-03-21 Paul Eggert <eggert@twinsun.com>
13469 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13470 problem with here-document buffer boundaries.
13472 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13473 when reinvoking the shell, to work around problems with installers
13474 who put strange things like "cd" commands in their environments.
13476 2002-03-19 Akim Demaille <akim@epita.fr>

13494 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

13499 (Limitations of Usual Tools): Add mkdir section.
13501 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13502 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13503 back on AS_DIRNAME to compute prefixes otherwise; this is
13504 roughly what mkinstalldirs does. That way, we need not have
13505 our own filename disassembler. The old disassembler did not
13506 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13508 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13509 Create at_test_all by a series of assignments,
13510 not by a single assignment of a long string. The latter causes ksh
13511 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13512 presumably because of a buffer overrun.
13514 2002-03-14 Paul Eggert <eggert@twinsun.com>
13516 * lib/autotest/general.m4 (at_times_skip):
13517 Renamed from at_times. Now a boolean.
13518 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13519 says 'times: not found'.
13521 2002-03-14 Akim Demaille <akim@epita.fr>
13523 * bin/autoreconf.in (&study_gettextize): New.
13524 (&autoreconf): Handle newest gettextize.
13525 Rerun aclocal if needed.
13526 Suggested by Andreas Schwab.

13551 does not do it if --with-lispdir is given.

13560 subdirectory should exist.
13562 2002-03-08 Akim Demaille <akim@epita.fr>
13564 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13566 2002-03-08 Akim Demaille <akim@epita.fr>
13568 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13569 aliases the actual variables, and modifications of the former
13572 2002-03-08 Akim Demaille <akim@epita.fr>
13574 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13575 because of C-c: have m4 output in tmp files, then mv them.
13577 2002-03-08 Akim Demaille <akim@epita.fr>

13598 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13599 * lib/autoconf/general.m4 (AC_INIT): More informative error
13600 message for LIBOBJ.
13602 2002-03-04 Akim Demaille <akim@epita.fr>

13607 2002-03-04 Akim Demaille <akim@epita.fr>
13609 * doc/autoconf.texi (Transforming Names): Equality between target
13610 and host is irrelevant.
13611 (Specifying Names, Canonicalizing): Remove all references to the
13612 backward compatibility hooks. Rather, collect them all into...
13613 (Hosts and Cross-Compilation): this new section.
13614 * doc/install.texi (System Type): Ditto.
13615 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13616 that `--host' implies cross-compilation.
13618 2002-03-04 Akim Demaille <akim@epita.fr>
13620 * doc/autoconf.texi (Evaluation Macros): New.
13621 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13623 (_m4_foreach): Define the variant with immediate evaluation so
13624 that it contains exactly the items, not an expression which
13625 evaluation is the current item.
13626 (m4_re_string, m4_re_word): Don't over quote them.
13628 2002-03-04 Akim Demaille <akim@epita.fr>
13630 Instead of having stacking `shift's evaluated at the end, let
13631 `foreach' loops immediately evaluate them.
13633 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13634 $*. This is the n-th time I change my mind, but hopefully this is
13637 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13639 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13640 it was only a hack for m4_text_wrap.
13641 (m4_car2): Remove, replaced by...
13643 (_m4_foreach): Adjust.
13644 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13645 m4_bpatsubst for clarification.

13696 Fix Autoconf PR/207:
13697 AC_PREFIX_PROGRAM fails with dashed program names
13699 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

13736 2002-02-05 Akim Demaille <akim@epita.fr>
13738 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13761 optional are the sum of the previous files on the command line'.
13762 Also, pass `--reload-state=' on them, so...
13763 (handle_m4): don't.
13764 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13765 (M4sh): Rely on M4sugar.
13766 (Autotest, M4sh, M4sugar): Use frozen files.

13792 2002-01-29 Akim Demaille <akim@epita.fr>
13794 * tests/torture.at (Configuring subdirectories): Use configure.in,

13796 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13798 2002-01-28 Akim Demaille <akim@epita.fr>
13800 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13803 2002-01-28 Akim Demaille <akim@epita.fr>
13805 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13806 AUTOTEST_PATH *after* it was set.
13807 Don't put `.' in the PATH: the user should be precise and `./' if
13808 needed. In addition, given that the test suite does some `cd', if
13809 `.' is in the path, the `tested programs' sections will report
13810 programs found in the test suite's directory, while during the
13811 tests (performed in their own directory), these programs are no
13812 longer visible. In other words, the results is confusing and

13879 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13880 package.m4, since is really depends upon configure.ac, not
13882 * doc/autoconf.texi (testsuite Scripts): Adjust.
13883 * tests/Makefile.am (package.m4): New.
13884 EXTRA_DIST it since its a source.
13886 2002-01-06 Akim Demaille <akim@epita.fr>
13888 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13889 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13890 and PACKAGE_BUGREPORT from here...
13891 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13893 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13894 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13895 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13896 * tests/tools.at (autoheader): Adjust.
13897 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

13905 * doc/autoconf.texi (Output): Improved wording regarding use of
13909 2001-12-18 Kevin Ryde <user42@zip.com.au>
13911 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13912 sometimes needing writable input.
13914 2001-12-17 Jim Meyering <meyering@lucent.com>
13916 * doc/autoconf.texi (New Macros): Tweak wording.
13918 2001-12-14 Akim Demaille <akim@epita.fr>
13920 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13921 trailing files, don't apply `-rf' to files which might not be
13922 created by configure (core, core.*, and *.core), but just `rm -f'.
13923 Suggested by Jonathan Kamens.
13925 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13927 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13929 2001-12-14 Akim Demaille <akim@epita.fr>
13931 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13933 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13935 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13936 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13937 abs_srcdir, top_srcpath to abs_top_srcdir.
13938 (_AC_OUTPUT_FILES): Adjust.
13939 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13940 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13941 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13943 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13945 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13946 C/Fortran linking on HP/UX, by extracting the Fortran library
13947 search path from the LPATH line in the $F77 -v output.
13949 2001-12-12 Kevin Ryde <user42@zip.com.au>
13951 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13952 forbidden file descriptors table.
13954 2001-11-26 Akim Demaille <akim@epita.fr>
13956 * bin/autoscan.in (%c_keywords): Build it at top level.
13957 Map to 1 in order to simplify its uses.
13959 2001-11-26 Akim Demaille <akim@epita.fr>
13961 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13962 Remove $filepath, useless.
13963 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13964 variables, they are really part of the tokens.
13965 Split the input line on spaces and then look for tokens.
13966 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13967 because of `lex$U.$(OBJEXT)'.
13968 (&scan_files): Use "@list" instead of join.
13969 * doc/Makefile.am (CLEANFILES): Add *.fns.
13971 2001-11-26 Akim Demaille <akim@epita.fr>
13973 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13974 Remove, replaced by...
13975 * tests/wrappl.in: Be common for all the Perl executables.
13976 In particular autoscan and autoheader want -I.
13977 * configure.ac: Adjust.
13978 * lib/autoscan/headers: errno.h is portable.
13980 2001-11-26 Akim Demaille <akim@epita.fr>
13982 * bin/autoscan.in (used): New.
13985 2001-11-26 Akim Demaille <akim@epita.fr>
13987 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13989 (&scan_sh_file): Remove a duplicate pattern.
13990 (&check_configure_ac): Use long options.
13991 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13993 2001-11-26 Akim Demaille <akim@epita.fr>
13995 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13996 Before, having a line containing the opening of a multi line
13997 comment made the whole line be ignored.
13999 2001-11-26 Akim Demaille <akim@epita.fr>
14001 * doc/autoconf.texi (Using an Autotest Test Suite): New.
14002 (testsuite Scripts): Be one of its subsection.
14003 (Autotest Logs): New.
14005 2001-11-26 Akim Demaille <akim@epita.fr>
14007 Test groups are now run two directories deeper.
14009 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
14010 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
14012 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
14013 top_srcdir, builddir and top_builddir.
14014 Use `at_*dir' relatively to the directory containing the
14015 suite, use `*dir' when relatively to the current group dir.
14017 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14019 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14020 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14021 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14024 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14026 * doc/autoconf.texi (Using System Type): Add an example of `case
14027 $host' usage so people quit using `case $target' everywhere.
14029 2001-11-22 Akim Demaille <akim@epita.fr>
14031 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14032 spotted by Jim Meyering.
14034 2001-11-16 Paul Eggert <eggert@twinsun.com>
14036 This patch implements a `long double' suggestion by Oliver Kiddle.
14038 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14039 static, to catch errors if the value isn't known at compile-time
14040 and the compiler supports dynamic arrays. Change its name from
14041 `_array_' to `test_array' to avoid potential name clashes.
14042 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14043 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14044 better than double. Catch a bug in GCC 2.95.2 x86.
14045 * doc/autoconf.texi (C Compiler): Document the above.
14048 2001-11-13 Akim Demaille <akim@epita.fr>
14050 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14052 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14054 2001-11-13 Akim Demaille <akim@epita.fr>
14056 * lib/autotest/general.m4 (AT_INIT): After having run the test
14057 group, go back to the initial directory, not to at_suite_dir.
14059 2001-11-13 Akim Demaille <akim@epita.fr>
14061 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14062 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14063 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14065 (AT_CHECK_CONFIGURE): Use absolute paths.
14066 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14067 The problem is still the old one: there is no means in M4 (that I
14068 know about) to create a defining macro, because there is no means
14069 to create `$1' etc., therefore, the defining macro ``swallows''
14070 all the arguments meant to the defined macro.
14072 2001-11-13 Akim Demaille <akim@epita.fr>
14074 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14075 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14077 * tests/aclocal.m4: Remove, as it is no longer used.
14079 2001-11-13 Akim Demaille <akim@epita.fr>
14081 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14082 variable names when referring to a single test group, or to
14083 `suite' when referring to the whole test suite.
14084 `at_last_test' is removed: m4 compute at_format itself.
14085 (at_stdout, at_stder1, at_stderr): New variables.
14086 (AT_CHECK): Use them.
14088 2001-11-13 Akim Demaille <akim@epita.fr>
14090 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14092 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14093 Do it as soon as a test fails, don't wait till the end of the test
14095 Don't remove $as_me.[0-9]*, since these files no longer exist.
14097 2001-11-13 Akim Demaille <akim@epita.fr>
14099 * tests/tools.at: Use absolute paths, since we are no longer run
14102 2001-11-13 Akim Demaille <akim@epita.fr>
14104 Now that tests are running in their own private dir, there is no
14105 need to list the files to remove at the end of tests groups.
14107 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14108 (AT_data_files, at_data_files): Remove.
14109 (AT_CLEANUP, AT_DATA): Simplify.
14111 Remove the group dir if !debug && !failed.
14112 * tests/atspecific.m4: Adjust.
14114 2001-11-13 Akim Demaille <akim@epita.fr>
14116 Start a new layout for Autotest: `testsuite' creates
14117 `testsuite.dir' in which the at-check-line etc. files are to be
14118 found, and `testsuite.dir/003' where the test group 3 is run.
14120 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14121 at_check_line_file, at_format, at_test_normalized, at_group_dir
14123 Create the directories.
14124 Use absolute paths for at- files.
14125 (AT_CHECK): Adjust.
14127 2001-11-11 Michael Matz <matz@kde.org>
14129 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14131 (m4_car): Properly quote arguments.
14133 2001-11-13 Akim Demaille <akim@epita.fr>
14135 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14136 with stricter rules on LIBOBJS.
14138 2001-11-12 Paul Eggert <eggert@twinsun.com>
14140 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14141 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14144 2001-11-12 Akim Demaille <akim@epita.fr>
14146 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14148 2001-11-12 Akim Demaille <akim@epita.fr>
14150 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14151 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14152 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14153 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14154 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14155 specify to what the macro should be defined (typically to 1).
14157 2001-11-12 Akim Demaille <akim@epita.fr>
14159 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14162 2001-11-12 Akim Demaille <akim@epita.fr>
14164 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14165 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14166 definition used by Automake where LEX is +/- "${missing} lex" and
14167 `missing' itself contains variables.
14169 2001-11-12 Akim Demaille <akim@epita.fr>
14171 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14172 Now that M4sh pushes BODY, the comments were output at the end of
14175 2001-11-08 Akim Demaille <akim@epita.fr>
14177 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14178 that we can trace macros from aclocal.m4.
14179 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14180 obsoleted, and redirect to the former anyway.
14181 Reported by Ralf Corsepius.
14183 2001-11-08 Akim Demaille <akim@epita.fr>
14185 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14186 processed only if present.
14187 * tests/torture.at (Configuring subdirectories): Use autoreconf
14188 instead of successive calls to autoconf.
14189 Add a nonexistent subdirectory to exercise the patch above.
14190 Reported by Ralf Corsepius.
14192 2001-11-08 Kevin Ryde <user42@zip.com.au>
14194 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14195 doesn't accept .S files.
14197 2001-11-07 Akim Demaille <akim@epita.fr>
14199 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14200 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14201 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14202 * bin/autom4te.in (warn_forbidden): New.
14203 (handle_output): Use it.
14204 Read m4_pattern_forbid with messages.
14206 2001-11-05 Akim Demaille <akim@epita.fr>
14208 * bin/autom4te.in (--normalize): Remove.
14209 * lib/autom4te.in: Adjust.
14211 2001-11-05 Akim Demaille <akim@epita.fr>
14213 * tests/Makefile.am (testsuite): Rename this target as...
14214 ($(TESTSUITE)): this.
14217 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14219 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14220 the --prefix option, also remove it's argument.
14222 2001-11-05 Akim Demaille <akim@epita.fr>
14224 * doc/autoconf.texi (testsuite Invocation): Update.
14225 (Writing testsuite.at): Update.
14227 2001-11-03 Akim Demaille <akim@epita.fr>

14231 2001-11-03 Akim Demaille <akim@epita.fr>
14233 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14234 (&file_name_is_absolute): New, wrappers around routines from
14236 Use and export them.
14237 (&find_configure_ac): Optionally take a directory where to look at.
14238 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14240 Default @ARGV to `.', not find_configure_ac.
14241 (&autoreconf): Argument is a directory.
14242 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14243 * doc/autoconf.texi (autoreconf Invocation): Update.
14245 2001-11-03 Akim Demaille <akim@epita.fr>
14247 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14248 (@export_forward_subs): New.
14249 Add basename, dirname, and fileparse.
14251 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14252 Don't look for aclocal flags if we already know aclocal is not
14254 Move aclocal.m4t only if it exists.
14255 Reported by Ezra Peisach.
14257 2001-11-03 Akim Demaille <akim@epita.fr>
14259 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14260 passed on command line, defaulting to ./configure.ac if present.
14261 (&maybe_autoreconf, File::Find): Remove, unused.
14262 (&autoreconf): If autoconf is not used, don't try to trace.
14264 2001-11-02 Akim Demaille <akim@epita.fr>
14266 * configure.ac: Bump to 2.52g.
14268 2001-11-02 Akim Demaille <akim@epita.fr>
14272 2001-11-02 Akim Demaille <akim@epita.fr>
14274 * config/config.guess, config/config.sub, doc/standards.texi:
14275 * config/lispdir.m4: Update from masters.
14276 * configure.ac: Bump to 2.52f.
14278 2001-11-02 Akim Demaille <akim@epita.fr>
14280 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14281 Don't run aclocal when aclocal.m4 is not from aclocal.
14283 Don't run libtoolize and gettextize if --install is not given.
14285 2001-11-01 Paul Eggert <eggert@twinsun.com>
14287 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14288 be invoked before _AS_LINENO_PREPARE.
14289 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14290 than character ranges.
14292 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14293 invoking AS_BASENAME. Set the locale variables to 'C' if
14294 possible, as POSIX requires this to get the traditional
14296 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14298 2001-10-31 Paul Eggert <eggert@twinsun.com>
14300 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14301 with {}, as that triggers a bug in Bash 2.05.
14303 (_AS_LINENO_PREPARE): Use Sed rather than
14304 Awk. Fix the sed prepass to work even if there are multiple
14305 instances of $LINENO on the same line. Do not substitute for
14306 other variables like $LINENOT. Do not check file dates; such a
14307 check is unreliable on sufficiently fast machines, and removing
14308 the check makes the code simpler and more reliable. Check for
14309 output and chmod failures.
14311 * doc/autoconf.texi (Special Shell Variables): Document
14314 2001-10-31 Akim Demaille <akim@epita.fr>
14316 * tests/Makefile.am (atconfig): Remove this target, Automake
14319 2001-10-31 Akim Demaille <akim@epita.fr>
14321 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14322 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14323 provided, while it is optional.
14324 * configure.ac: Adjust.
14326 2001-10-26 Paul Eggert <eggert@twinsun.com>
14328 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14329 lib/Autom4te/Struct.pm:
14330 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14333 * doc/autoconf.texi (Special Shell Variables): Document some
14334 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14336 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14337 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14338 eval $LINENO is not portable in practice.
14340 2001-10-24 Akim Demaille <akim@epita.fr>
14342 * lib/Autom4te/General.pm (backname): New.
14344 2001-10-24 Akim Demaille <akim@epita.fr>
14346 * m4/: Remove, merged into...
14349 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14351 * doc/autoconf.texi (Shellology): Mention the problems with bash
14352 2.05's use of ANSI quoting in its `set' builtin.

14356 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14357 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14358 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14359 POSIX decided to standardize on the int flavor of strerror_r.
14360 Always do char* test, as there's no reason not to.
14361 Assign to a char* var, to catch strerror_r that returns int*.
14363 * doc/autoconf.texi (Particular Functions):
14364 Document the above changes. Also, document the fact that
14365 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

14856 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
14857 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
14858 be used instead of ':'.
14859 * lib/autotest/general.m4: Replace occurrences of ':' in
14860 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14862 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14864 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14865 arguments. Fixed a typo.
14867 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14869 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14870 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14872 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14874 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

14881 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14883 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14884 already have $file). Set output files to binary mode (helps avoid
14885 CR issues on DOSish systems).
14887 2001-09-19 Akim Demaille <akim@epita.fr>
14889 * lib/autotest/general.m4: Englishoes.
14890 From Tim Van Holder and Alexey Mahotkin.
14892 2001-09-18 Paul Eggert <eggert@twinsun.com>
14894 * doc/autoconf.texi (Common Shell Constructs): New node,
14895 documenting AS_DIRNAME.
14896 (Limitations of Usual Tools): Refer to it when discussing dirname.
14897 Also, update discussion of POSIX standard to reflect latest draft.
14899 * lib/autoconf/c.m4:
14900 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14902 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14903 Do not pass a first argument with leading '-'
14904 to expr, by parenthesizing initial integers that might be negative.
14906 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14907 now merely checks whether it is an error to pass an argument
14910 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14911 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14912 whether it is a (compile-time) error to pass an argument to
14913 getpgrp. This simpler test supports the revised documentation,
14914 and is all that AC_FUNC_GETPGRP's users really need.
14916 2001-09-18 Akim Demaille <akim@epita.fr>
14918 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14926 2001-09-18 Paul Wagland <paul@wagland.net>
14928 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14930 Add test for AS_BASENAME.
14931 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14932 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14933 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14934 * tests/base.at: Fixed the expected responses. The old ones were
14936 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14937 the documentation claims it should (and how it behaved in 2.13).
14939 2001-09-18 Akim Demaille <akim@epita.fr>
14941 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14942 the AC_CONFIG_COMMANDS invocation.
14943 This also solves the name clash problems.
14944 Don't set the package's ID.
14945 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14946 No longer to be shipped.
14947 (version.in): Remove.
14948 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14949 * lib/autoconf/status.m4: Adjust.
14950 Use `m4_PACKAGE_STRING'.
14951 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14952 the only optional argument is the name of the test suite.
14953 Expect `package.m4' to define the package signature.
14954 * lib/autom4te.in (Autotest): Add `package.m4?'.
14955 * tests/Makefile.am (package.m4): New.
14956 * tests/suite.at: ifnames is a victim.
14958 2001-09-18 Akim Demaille <akim@epita.fr>
14960 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14961 AC_LIBSOURCE, AC_CONFIG_FILES.
14962 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14963 program version string doesn't match the package's.
14964 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14967 2001-09-17 Paul Eggert <eggert@twinsun.com>
14969 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14970 Allow expression to return any value that can fit into unsigned long
14971 (not int, as before). Check for output errors.
14973 2001-09-17 Bruno Haible <haible@ilog.fr>
14975 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14976 Always include <stdio.h> and <stdlib.h>. Evaluate
14977 the expression in an extra function before these includes. Call
14978 fprintf "%d" only after ensuring the argument is of type 'int'.
14979 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14981 2001-09-17 Paul Eggert <eggert@twinsun.com>
14983 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14984 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14985 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14986 when they don't exist.
14988 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14989 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14992 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14993 version with the version used by fileutils 4.1, except use
14994 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14997 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14999 2001-09-13 Akim Demaille <akim@epita.fr>

15039 * lib/autotest/general.m4 (AT_INIT): Create and remove
15040 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15041 test suites can cohabit.
15043 2001-09-13 Akim Demaille <akim@epita.fr>
15045 * tests/mktests.sh: Don't output banners for empty test files.

15097 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

15100 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

15151 2001-09-05 Akim Demaille <akim@epita.fr>
15153 Be ready to handle filenames as stupid as `dnl.at', for if even
15154 the maintainer is dumb enough to do that...
15156 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15157 excellence in M4 quotation: consider `__file__' is active.
15159 And BTW, when invoking m4, pass the --include in the right order:

15240 * man/Makefile.am (.x.1): We really have to pass
15241 autom4te_perllibdir.

15245 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
15246 debug scripts, in particular passing explicitly listed tests to

15294 * bin/autoupdate.in, bin/autoheader.in: Adjust.
15295 Drop AC_MACRODIR dead for real.
15296 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15297 `autoheader: `config.hin' is created'.
15298 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15300 2001-08-31 Akim Demaille <akim@epita.fr>
15302 * bin/autoheader.in: Rewrite in Perl.

15307 * bin/autoconf.in (--include, -I): New option.
15308 Map --localdir, --autoconf-dir onto it.
15309 Forward autom4te's options instead of interpreting them.
15310 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15311 There is no such envvar since the inception of autom4te.cfg.
15312 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15313 * bin/autoupdate.in: Adjust, and perform more control.
15314 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15315 * tests/autoconf: Dittowise.
15317 2001-08-31 Akim Demaille <akim@epita.fr>

15323 (&parse_args): Adjust.
15324 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

15333 * lib/Autom4te/General.pm (&find_peer): Remove.
15334 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

15336 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15337 find the executables for it.
15338 * tests/Makefile.am: Major cleanup. Too lazy to document...
15339 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15341 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15342 indeed related to running the test suite, while passing
15343 --autoconf-dir and others is related to running non installed
15344 Autoconf executables. So don't do that, leave it to...

15346 * tests/autoscan: New.
15347 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

15364 Suggested by Paul Eggert.
15366 2001-08-29 Akim Demaille <akim@epita.fr>

15833 autom4te.cache (it's a directory, not a file.
15834 * Makefile.am: Ditto (but maintainer-clean-local).
15836 2001-08-15 Akim Demaille <akim@epita.fr>
15838 * bin/autom4te.in (@m4_warning): New.
15839 (&handle_m4): Use it.
15840 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15841 warnings are issued at each run.

15920 magic values from an object file when cross-compiling.
15921 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15923 2001-08-10 Akim Demaille <akim@epita.fr>
15925 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15927 Suggested by Russ Allbery.
15929 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15931 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15932 current $prefix to the sub-configures.
15934 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15936 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15937 extension (needed on BeOS). Reported by Guido van Rossum.
15939 2001-08-09 Akim Demaille <akim@epita.fr>
15941 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15943 2001-08-07 Akim Demaille <akim@epita.fr>
15945 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15947 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15948 No need to remove the files before and after the each test, before
15949 each test and at the end of the suite is enough.
15950 Display only the children `times', not the shell's.
15951 If the test failed or was skipped, at-times is not available.
15953 2001-08-07 Akim Demaille <akim@epita.fr>
15955 Always produce testsuite.log, including when there are no
15956 failures. This helps getting information on skipped tests, and
15957 duration of the tests. Err, implement the latter btw.
15959 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15960 Dump information on the first run of each test.
15961 (AT_CLEANUP): Create `at-times' containing the duration of the
15964 2001-08-07 Akim Demaille <akim@epita.fr>
15966 The use of `dumpstat' revealed that `len' was used although it
15967 should not. m4_text_wrap was using it, but in the Autoconf world
15968 where it is legal. Hence (i) test M4sh in its own world, not
15969 Autoconf's, and (ii), ahem, fix the bug :)
15971 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15972 does not like `' instead of [].
15973 (AT_INIT): Forbid `^_?AT_'.
15974 And don't output such tokens.
15975 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15976 `script.as', and `autom4te.cache'.
15977 Remove `empty' and `macro' which are no longer used.
15978 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15979 * tests/m4sugar.at: Use it.
15980 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15982 2001-08-07 Akim Demaille <akim@epita.fr>
15984 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15986 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15988 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15990 2001-08-04 Akim Demaille <akim@epita.fr>
15992 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15993 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15995 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15996 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15997 (AC_F77_MAIN): Likewise.
15999 2001-08-04 Akim Demaille <akim@epita.fr>
16001 Don't rely on M4sugar outputting the patterns in files, since we
16002 might process the output _without_ running m4, hence without these
16005 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
16006 * bin/autom4te.in (@Request::includes): Remove, unused.
16007 (@Request::source): Rename as...
16008 (@Request::input): this.
16009 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
16010 (&handle_output): Fetch the patterns from the traces.
16011 `$forbidden' and `$allowed' are constant: use m//o.
16012 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
16013 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
16015 2001-08-04 Akim Demaille <akim@epita.fr>
16017 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
16018 autoconf', i.e., in addition to caching traces, cache the output.
16020 * bin/autom4te.in (Request::cache): Rename as...
16021 (Request::id): this.
16022 ($cache, $icache, $tcache, $ocache): New.
16023 (&handle_m4): Save M4 output in the cache instead of $tmp.
16024 (&handle_output): Adjust.
16025 (&up_to_date_p): Check that the output cache is up to date too.
16026 (top level): Run `&handle_m4' iff force or the cache is invalid.
16027 Run `&handle_output' if the output cache is more recent.
16029 2001-08-04 Akim Demaille <akim@epita.fr>
16031 * bin/autom4te.in ($force): New.
16032 (&parse_args, &print_usage): -f, --force is a new option.
16033 (&handle_output): CPP directives might have spaces after `#'.
16034 (&parse_args): The first file only can be frozen.
16036 2001-08-04 Akim Demaille <akim@epita.fr>
16038 Don't let autom4te compute the `include' traces several times:
16039 first check that the trace cache file is up to date, and then
16040 compare its timestamp with that of the output.
16042 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16043 the preamble. Don't require 5.005 as Autom4te::General does it,
16044 and better yet (use `use', not `require'!).
16045 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16046 Class::Struct as Autom4te::Struct.
16047 * lib/Autom4te/General.pm (File::stat): Use it.
16048 (&mtime): New, export it.
16049 * bin/autom4te.in: Use it.
16050 Declare `$req' is invalid if it is outdated.
16051 Don't declare it valid before saving it if something went wrong.
16053 2001-08-04 Akim Demaille <akim@epita.fr>
16055 Autom4te shall not encode Autoconf data, and preselecting traces
16056 must be proposed to the users.
16058 * bin/autom4te.in (@required_trace): Remove.
16060 (&parse_args, &print_usage): -p, --preselect is a new option.
16061 (&up_to_date_p): Adjust.

16096 m4_if, and m4_wrap.

16101 (m4_divert_pop): Dump the whole diversion stack when a diversion
16103 * bin/autom4te.in (&handle_output): Remember of the first
16104 occurrence of a possibly undefined macro, not the last.
16105 Complain about the possibly undefined macros in the same order as
16106 the appear in the output.
16107 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16108 * tests/tools.at (autoconf: forbidden tokens, basic)
16109 (autoconf: forbidden tokens, exceptions): No longer sort
16110 autoconf's stderr, as it is now deterministic.
16111 Check that `dnl' is caught.
16113 2001-08-01 Akim Demaille <akim@epita.fr>

16135 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
