2030 Fix thinko in earlier patch - m4_join isn't defined yet.
2031 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
2032 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
2033 (m4_require): Use m4_do, not m4_join.
2035 Fix some whitespace tests on cygwin.
2036 * tests/tools.at (autom4te and whitespace in file names): Restore
2037 font-lock. Create $TMPDIR before it might be used.
2039 Fix spurious testsuite failure with M4 1.4.11.
2040 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
2042 Optimize AC_REQUIRE.
2043 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
2044 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
2045 (m4_require): Avoid extra macro calls.
2047 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2049 * tests/torture.at (srcdir): Fix quoting.
2051 Do not pass top_srcdir to configure scripts in testsuite.
2052 * tests/autotest.at (srcdir propagation): Copy install-sh to
2054 (my only test): Drop setting of `top_srcdir'.
2055 * tests/base.at (Input/Output): Likewise.
2056 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
2057 config.guess, and config.sub to test source tree.
2058 Drop AC_CONFIG_AUX_DIR setting.
2059 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
2060 * tests/torture.at (Substitute a 2000-byte string): Drop
2061 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
2062 (Substitute a newline, datarootdir workaround): Likewise.
2063 (Define a newline): Adjust for linenumber changes in configure.ac.
2064 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
2066 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
2067 if `pwd` contains whitespace.
2069 Quote $abs_top_srcdir in tests.
2070 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
2071 * tests/tools.at (Syntax of the shell scripts): Likewise.
2073 * tests/m4sh.at (LINENO): Quote $0.
2075 Fix testsuite program wrapper for whitespace in `pwd`.
2076 The problem here is that the usual mantra is that command
2077 variables can contain arguments, thus we cannot just escape
2078 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
2079 $top_builddir/tests directory early in $PATH, so that the
2080 wrappers are found by their plain name.
2081 * tests/wrapper.as: Put $testdir early in $PATH.
2082 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
2084 Proper config.status --file/--header and $srcdir escaping.
2085 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
2086 characters in $ac_file_inputs.
2087 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
2089 * tests/torture.at (datarootdir workaround): Adjust.
2090 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
2092 Fix Autotest for whitespace in `pwd`.
2093 * lib/autotest/general.m4 (AT_INIT)
2094 <at_func_create_debugging_script, Driver Loop>:
2095 Quote $at_group_dir.
2096 * tests/autotest.at (whitespace in absolute testdir): New test.
2098 * lib/autom4te.in: Quote @datadir@.
2100 Proper file name escaping in Autoconf programs and Perl modules.
2101 This includes escaping of characters special to the shell
2102 as well as special to Perl, e.g., leading `<' or `>'.
2103 For example, when $file starts with `>', `open ">$file"'
2104 wrongly tries to append to a different file.
2105 * bin/autoconf.as: Fix quoting for autom4te options.
2106 * lib/Autom4te/General.pm (shell_quote): New function, taken
2107 from coreutils, written by Jim Meyering.
2109 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
2111 * bin/autoreconf.in (parse_args): Likewise.
2112 * bin/autoscan.in (main): Likewise.
2113 * bin/autoupdate.in (main): Likewise.
2114 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
2115 * bin/ifnames.in: Likewise, XFile usage fixes.
2116 * tests/tools.at (autom4te and whitespace in file names): Extend
2117 test. Test twice, with special characters allowed on w32, and the
2118 rest. Test leading and trailing whitespace, for `open_quote'.
2119 (autotools and whitespace in file names): New, analogous test.
2120 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
2121 by Russ Allbery and Eric Blake.
2124 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
2125 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
2126 * lib/Autom4te/FileUtils.pm (open_quote): New function.
2127 (update_file, contents): Use it.
2129 * Makefile.am (autom4te-update): Rewrite for git.
2131 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2133 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
2135 Fix copyright years.
2136 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
2137 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
2139 2007-12-04 Eric Blake <ebb9@byu.net>
2141 Manually resync with gnulib, since 'make cvs-update' no longer works.
2142 * build-aux/config.guess: New upstream version.
2143 * build-aux/config.sub: Likewise.
2145 When using older automake, don't downgrade build-aux/texinfo.tex.
2146 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
2147 * doc/Makefile.am (TEXINFO_TEX): Add.
2149 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2151 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2152 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2153 #undef as this runs afoul of our new way of creating config.h.
2154 Problem reported by Jim Meyering in
2155 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2157 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2159 Fix autom4te for unusual characters in input file names.
2160 * bin/autom4te.in (files_to_options): Quote active characters
2162 * tests/tools.at (autom4te and white space in file names):
2165 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2166 Document that Tru64 awk always splits $0.
2168 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2170 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2171 `#AT_STOP_...' line at the end of each test.
2173 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2175 * lib/autotest/general.m4 (AT_INIT): For awk line number
2176 extraction script, ensure `$at_group' has a defined value
2177 even for the empty set, and properly quote its usage inside
2180 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2182 * doc/autoconf.texi (Shell Functions): New chapter. Document
2183 IRIX sh $0 issue in functions, move content from ...
2184 (Portable Shell): ... here.
2185 (Shell Script Compiler): Note that shell functions are not
2186 totally unportable any more.
2188 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2189 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2191 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2192 extracting the line numbers of the last needed test.
2194 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2196 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2199 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2201 Fix IRIX testsuite debugging failures: $0 in functions.
2202 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2203 Do not use $0 inside a function, as IRIX sh will set that to the
2204 function name rather than the script invocation name.
2206 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2207 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2209 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2210 to extract test scripts.
2211 (AT_INIT): Extract and cache test script line numbers.
2213 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2215 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2216 subsequent fixups; the awk -> here-document conversion trashes
2217 performance too much with AIX sh.
2219 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2221 * tests/local.at: Do not test m4, perl with AT_TESTED.
2223 Diagnose and guard against write errors dealing with config.status.
2224 The general idea is this: all write failures from `configure'
2225 writing `config.status' are indicated by $ac_write_error, which
2226 is only checked at the end. This is safe because config.status
2227 code is not executed before the file is complete. Other write
2228 failures, be they inside config.status, or in sub shell/awk
2229 scripts spawned from configure or config.status, typically need
2230 earlier checking, as their results are used right afterwards.
2231 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2232 before writing config.status, check afterwards.
2233 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2234 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2235 Set `ac_write_error' for write failures to config.status. Barf
2236 upon write failures to temporary files.
2237 Adjust note about closing and reopening the here-document.
2238 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2239 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2240 reopening the here-document.
2241 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2242 Ensure `ac_write_error' does not escape into config.status.
2243 Also, add a couple of code paths not yet exercised in the test
2244 suite: a config file with input from stdin, and a config header
2246 Suggestion for catching write errors by Bruno Haible.
2248 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2250 Avoid error with Tru64 awk and testsuite lines with many words.
2251 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2252 reads the testsuite, set the field separator to an unusual value,
2253 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2254 even splits the input if $i, i>0, was never accessed in the script.
2256 Revert 2007-10-17 change.
2257 * TODO: Multiline args in config files and headers mean something
2258 different and are not fixed, see
2259 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2260 Report by Stepan Kasal.
2262 * doc/autoconf.texi (Generic Programs): Fix typo.
2264 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2266 AC_*_TOOL does not canonicalize the prefix
2267 * doc/autoconf.texi (Generic Programs): Do not say that
2268 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2270 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2272 Diagnose write errors in config.status instantiations.
2273 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2274 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2276 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2277 Extend test to also check for some write error failures, using...
2278 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2279 Report by Bruno Haible.
2282 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2284 (_AT_CHECK): Use less indentation, to save space.
2286 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2288 Add witness macro for @top_build_prefix@ substitution.
2289 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2290 (_AC_OUTPUT_FILE): Mention it here.
2292 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2293 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2295 * lib/autotest/general.m4 (at_func_test): Remove.
2296 (AT_INIT): Pre-extract test groups into separate files.
2297 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2298 Remove at-test-source files together with the $at_group_dir.
2299 * tests/autotest.at (Long test source lines): New test.
2301 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2303 Shell functions and variables may share a namespace.
2304 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2307 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2309 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2312 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2314 * lib/autoconf/status.m4: Fix a couple of comment typos.
2316 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2318 2007-11-13 Jim Meyering <meyering@redhat.com>
2320 Clean up the rule to create "expr".
2321 * tests/Makefile.am (expr): Don't redirect directly to target.
2322 Redirect just once, not for each echo statement.
2323 Use $@, not literal "expr".
2325 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2327 Don't worry about preprocessor when testing long long.
2328 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2329 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2330 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2331 These no longer check for preprocessor flaws.
2332 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2333 Do not check for preprocessor flaws.
2335 2007-11-13 Jim Meyering <meyering@redhat.com>
2337 Adapt dependencies, now that a version change doesn't modify configure.ac
2338 * GNUmakefile: Remove "make clean" kludge.
2339 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2341 Don't redirect directly to target.
2342 Use $@, not literal "version.m4".
2344 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2346 * doc/autoconf.texi (Making testsuite Scripts): Document
2347 ":;{" shorthand as in previous patch.
2349 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2351 * doc/autoconf.texi (Limitations of Builtins): Document problem
2352 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2354 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2355 Use ":;{" shorthand.
2356 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2358 2007-11-12 Jim Meyering <meyering@redhat.com>
2360 Add more non-srcdir build support.
2361 * GNUmakefile (dummy): Split a long line.
2362 Add -v option to autoreconf invocation.
2364 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2365 * GNUmakefile (dummy): Remove INSTALL.
2367 Remove racy commands to build scripts in bin/ and tests/.
2368 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2369 are guaranteed to be built, remove the rules that tried to build
2370 them. Before, with a parallel build, these rules could lead to
2371 two processes writing tests/wrapper.in concurrently.
2373 Build in man/ only *after* building in bin/ and tests/.
2374 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2375 in both bin/ and tests/.
2377 Accommodate non-srcdir build-from-checkout.
2378 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2379 Use git's --git-dir=$srcdir/.git option.
2380 Add quotes, in case tarball_version_file contains shell meta-characters.
2381 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2382 * configure.ac: Pass "." to git-version-gen.
2384 Avoid spurious test failures due to version skew.
2385 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2387 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2389 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2390 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2391 Remove conftest.dSYM directory.
2392 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2393 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2394 Remove `conftest.*' recursively.
2395 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2396 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2398 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2400 Report and analysis by Jeff Squyres and Peter O'Gorman.
2402 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2404 Fix typos in variable names.
2405 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2407 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2409 Document that $((expression)) is not portable.
2410 * doc/autoconf.texi (Shell Substitutions): Here.
2412 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2414 Ignore configure --help* errors due to LINENO-impaired shells.
2415 * tests/torture.at (Configuring subdirectories, Deep Package):
2416 In the --help* tests in read-only trees, make `.' temporarily
2417 writable again for the `stderr' file, and ignore errors due to
2418 the attempt to write configure.lineno.
2419 Report by Patrick Welche.
2421 2007-11-10 Jim Meyering <meyering@redhat.com>
2423 Generate package.m4 in build-dir, not srcdir.
2424 * tests/Makefile.am (package.m4): Adjust target.
2425 Don't redirect directly to $@.
2426 (CLEANFILES): Add package.m4.
2427 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2429 When running $(AUTOTEST), search "." before searching $(srcdir).
2431 Avoid a race condition that would make parallel "distclean" fail.
2432 * tests/Makefile.am (distclean-generic): Replace the default,
2433 automake-provided rule with an identical one, but with an additional
2434 dependency on distclean-local. Simply adding the dependency would
2435 cause automake not to emit the rule at all.
2436 * BUGS: Building with -jN works, now.
2438 Distribute git-version-gen.
2439 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2440 since GNUmakefile is distributed, and requires it for dist* rules.
2442 Remove two more generated files from version control.
2443 * INSTALL: Remove generated file.
2444 * lib/autoscan/autoscan.list: Remove generated file.
2446 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2448 * GNUmakefile (PATH): Remove stray apostrophes; they become
2449 part of PATH, which isn't wanted here.
2451 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2453 New config files output variable `top_build_prefix'.
2454 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2456 * doc/autoconf.texi (Preset Output Variables): Document it.
2458 Report by Bob Friesenhahn.
2460 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2461 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2462 function, to parametrize arithmetic with expr vs. the shell.
2463 Use it where possible.
2464 Suggestion by Benoit Sigoure.
2466 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2468 Adjust the documentation of autotest WRT atlocal.
2469 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2470 when using Automake, to write a rule to produce atlocal, since it's
2471 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2472 distributed, not atconfig.in.
2474 2007-11-04 Eric Blake <ebb9@byu.net>
2476 Update list information.
2477 * README: Mention new autoconf-commit list.
2478 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2480 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2482 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2484 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2486 * build-aux/.gitignore: Ignore mkinstalldirs.
2488 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2490 2007-11-03 Jim Meyering <meyering@redhat.com>
2492 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2493 * build-aux/git-version-gen: This syncs from coreutils.
2495 Adjust the build procedure so "make check" works reliably.
2496 * README-hacking: Include an extra step between "make" and
2497 "make check" to ensure that the latter passes.
2499 Use just-built tools, when possible.
2500 * GNUmakefile (PATH): Set and export here, ...
2501 (dummy): ... rather than here.
2503 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2504 and Andreas Schwab <schwab@suse.de>

2509 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2511 * configure.ac (AC_PREREQ): Require version 2.60, for

2573 Make inter-release --version output more useful.
2575 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2576 which indicates that it is built using the 19th change set
2577 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2578 is a prefix of the commit SHA1.
2579 * build-aux/git-version-gen: New file.

2589 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2590 git-version-gen doesn't match $(VERSION), but only for dist targets.

2663 Fix config header generation with AIX awk.
2664 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk

3996 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
3997 status of rm so we know when it failed.
3998 If cleaning of test dir failed before running the test, warn.
3999 Output the line separator in verbose mode before the warning
4000 to make clear the warning belongs to the following test.
4002 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
4004 * doc/autoconf.texi (Parentheses): Mention problem with (( in
4007 2007-02-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4008 and Paul Eggert <eggert@cs.ucla.edu>

4011 errors introduced in last change.
4013 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
4015 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
4016 an actual carriage return. Use "ac_cr" to contain the actual

4019 with traditional Awk and begin.
4020 * tests/torture.at (Limitations of Builtins): Document the problem
4021 with Bash 2.03 printf.
4022 (Substitute and define special characters):
4023 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
4025 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
4027 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
4028 input from /dev/null in awk test, so even Solaris /usr/bin/awk
4029 will not wait for input with a script containing only a BEGIN
4032 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
4034 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

4063 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4065 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
4066 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
4067 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
4068 substitution will still be done by the special code.

4083 Test all 8 bit non-NUL characters.
4084 Report against Automake by Patrick Welche.
4086 2007-01-15 Stepan Kasal <kasal@ucw.cz>
4088 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
4090 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4092 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
4093 early on the reader side, drop stderr of the input to avoid
4094 `broken pipe' error output; this may happen even with shell
4095 builtin `echo' of some bash versions. Reports by Ian Macdonald
4096 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
4098 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4100 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
4101 separate items of `ac_user_opts', to avoid long lines.
4102 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
4104 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4108 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
4110 Fix some wording problems noted by Paolo Bonzini in:
4111 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
4112 * doc/autoconf.texi (Signed Overflow Examples): Give more
4113 discussion about the allow_superuser_privileges example,
4114 and change it a bit to make things clearer.
4115 (Optimization and Wraparound): Clarify whether the compiler
4116 will generate an infinite loop for the example derived from
4117 Autoconf's mktime test.
4118 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
4119 Also, clarify unsigned multiplication overflow.
4121 2007-01-04 Eric Blake <ebb9@byu.net>
4123 * bin/Makefile.am (RELEASE_YEAR): New macro.
4124 (edit): Use it to supply correct copyright year to scripts.
4125 * bin/autoconf.as (version): Use it.
4126 * bin/autoheader.in ($version): Likewise.
4127 * bin/autom4te.in ($version): Likewise.
4128 * bin/autoreconf.in ($version): Likewise.
4129 * bin/autoscan.in ($version): Likewise.
4130 * bin/autoupdate.in ($version): Likewise.
4131 * bin/ifnames.in ($version): Likewise.
4133 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4135 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4136 feedback. The most important changes document what happens when
4137 you convert an out-of-range value to a signed integer type, and
4138 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4141 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4142 rewrite, taking notions from the recent discussion on the gcc and
4143 autoconf mailing lists; please see
4144 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4145 and follow the many links.
4146 (Integer Overflow Basics, Signed Overflow Examples):
4147 (Optimization and Wraparound, Signed Overflow Advice):
4148 (Signed Integer Division): New sections.
4150 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4152 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4153 preprocessor macro arguments in traced name.
4154 * doc/autoconf.texi (Defining symbols): Document longstanding
4155 support for AC_DEFINE-ing macros with arguments, and document
4156 behavior when the same variable has multiple AC_DEFINEs.
4157 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4158 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4159 macros directly, giving much shorter and simpler code.
4161 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4163 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4164 space before "$ac_configure_args" to prevent a 'config.status
4165 --recheck' failure if ac_configure_args doesn't contain a leading
4166 space. This works around a problem with the XEmacs configure.ac,
4167 which uses the (undocumented) ac_configure_args variable
4168 inconsistently with Autoconf.
4170 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4172 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4173 Include <limits.h>, and use its INT_MAX to rewrite the
4174 j loop so that it does not overflow 'int'. Problem reported by
4176 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4177 Play it safe by shifting left by 1 rather than multiplying by 2,
4178 as GCC is less likely to optimize this away when the value
4179 is signed (when it assumes overflow leads to undefined behavior).
4180 Also, don't assume time_t uses two's complement.
4182 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4184 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4185 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4186 dumps core on it. Report by Tim Rice.
4188 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4190 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4191 --disable-option-checking to --help output even when
4192 AC_PRESERVE_HELP_ORDER is not used.
4193 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4194 --with argument, rather than argument with [-.] replaced by
4196 * NEWS: Fix typo in previous change; the news was in the
4199 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4201 * NEWS: Warnings are now generated by default for unknown
4202 --enable-* and --with-* options.
4203 * doc/autoconf.texi (Option Checking): Renamed from
4204 (Configure Option Checking). Tighten up the wording a bit.
4205 (External Software, Package Options): Cross-reference to Option
4206 Checking, and use this to shorten our section.
4207 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4208 "$x" to test "x$foo" != x.
4209 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4210 Don't warn if $enable_option_checking is "no".
4211 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4212 ac_unrecognized_opts to the empty string.
4213 Don't echo the unrecognized opts, as this might mishandle
4214 backslashes or leading -.
4215 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4216 usage next to the other --disable-FEATURE options in the
4219 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4221 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4222 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4223 Print warning for unrecognized --with and --enable options
4224 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4225 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4226 Disable option checking when subdirs are configured.
4227 (AC_OUTPUT): If warnings are enabled, print warning about
4228 unrecognized --with and --enable options at the end of
4229 the configure output (as well as at the beginning).
4230 * doc/autoconf.texi (Option Checking): New node.
4231 Document new option warning functionality.
4233 2006-12-16 Eric Blake <ebb9@byu.net>
4235 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4236 * NEWS: Start news for current version.
4238 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4240 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4241 Define HAVE_GETMNTENT to 1, not to the empty string.
4242 Problem originally reported by Jochen Friedrich in
4243 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4245 This change prompted by a problem report by Andrey Simonenko in
4246 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4247 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4248 object-like macros only, in the traditional portable character
4250 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4251 Warn about attempts to define things that are not identifiers.
4252 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4253 awful hack that AC_DEFINEd macro names containing parentheses.
4255 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4257 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4258 too drastic, even if Texinfo in theory requires it for info mode.
4260 (config.status Invocation): Renamed back from Recreating a
4262 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4263 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4265 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4267 * NEWS: Version 2.61a.
4269 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4270 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4272 * NEWS: Document changes with echo and printf, and the lack
4273 of limits on the total size of multi-line values of substituted
4274 variables, and the AC_FUNC_FSEEKO fix.
4276 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4278 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4279 Writing configure.ac.
4280 (Autoconf Input Layout): Renamed from configure.ac Layout.
4281 (Recreating a Configuration): Renamed from config.status Invocation.
4282 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4283 (acconfig Header): Renamed from acconfig.h.
4284 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4285 (Writing Testsuites): Renamed from Writing testsuite.at.
4286 (Autom4te Cache): Renamed from autom4te.cache.
4288 * BUGS: Remove mention of VPATH problem, since it's now documented
4289 not to be a bug in the Autoconf build procedure itself, but rather
4290 a problem with the proprietary `make' programs.
4292 * doc/autoconf.texi (Build Directories): Add a cross reference
4295 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4296 * doc/standards.texi: Sync from gnulib.
4298 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4299 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4300 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4301 generated automatically.
4303 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4305 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4306 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4307 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4309 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4311 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4312 `CEOF$ac_eof' special marker, the awk script cannot contain a
4313 line matching `^CEOF', so this is not needed any more.
4314 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4315 special marker in the test.
4317 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4319 * tests/tools.at (autom4te preselections): Use `find -newer';
4320 remove one of the sleeps.
4322 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4323 more readable, using ...
4324 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4326 * doc/autoconf.texi (autoheader Invocation): Do not double-
4327 quote the parameter of `AH_BOTTOM' in the example.
4329 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4331 * doc/autoconf.texi (Configuration Headers): Remove the
4332 example with multiple input files.
4333 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4334 multiple input files.
4336 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4338 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4339 creating the awk substitution script, handle one input line at a
4340 time, so that the maximum length of a substituted (multi-line)
4341 value is not limited by the size of the sed pattern space.
4342 The trade-off is a slightly repetitive sed script.
4343 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4344 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4345 * tests/torture.at (Substitute a 2000-byte string): Increase the
4346 test with several long lines, they should not be caught by sed
4349 * tests/tools.at (autom4te preselections): New test, to flag
4350 entries missing from autom4te.cfg.
4351 Report by David Byron <dbyron@hheld.com>.
4353 * tests/torture.at (Substitute a 2000-byte string): Actually use
4354 AC_PROG_AWK, so the last change works as intended.
4355 (Substitute and define special characters): Likewise.
4356 (Substitute a newline): Likewise.
4358 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4359 instead of `awk' consistently.
4360 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4361 * tests/torture.at (Torturing config.status): Test both the
4362 result of AC_PROG_AWK and plain awk.
4363 (Substitute a 2000-byte string): Likewise.
4364 (Substitute and define special characters): Likewise.
4365 (Substitute a newline): Likewise.
4367 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4369 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4370 can be assigned to a function pointer. Problem reported by
4371 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4372 part of a patch by Ralf Wildenhues in that same bug report.
4374 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4376 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4377 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4379 2006-12-01 Eric Blake <ebb9@byu.net>
4381 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4382 cross-compiling from cygwin to mingw.
4383 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4384 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4385 to lib/autoconf/c.m4.
4387 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4389 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4390 string for more reliable failure. Wrap the entire test that
4391 causes the broken Solaris printf to dump core, in a subshell,
4392 so the segmentation fault message is reliably suppressed.
4393 Fix shell expansion errors by using /usr/ucb/echo always;
4394 avoid an error on systems without it by another subshell.
4395 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4396 subshell-$as_echo to `as_echo', for better error message.
4398 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4400 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4401 `BASH_SOURCE' contain a newline, set them to empty, as they may
4404 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4406 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4407 years and is too hard to maintain now. The last straw was
4408 reported by Jerker Baeck in
4409 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4410 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4411 * doc/autoconf.texi (Particular Functions): Move
4412 AC_FUNC_SETVBUF_REVERSED from here...
4413 (Obsolete Macros): ... to here. Say that it does nothing now.
4414 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4415 Turn into (almost) a no-op.
4417 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4419 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4420 These macros are obsolescent and new applications shouldn't need them.

4428 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4430 * doc/autoconf.texi (Setting Output Variables): Mention that
4431 @VAR1@VAR2 has unspecified behavior. Problem reported by
4433 * NEWS: Mention this.
4435 * Makefile.am: Put only a single '#' into the copyright notice,
4436 so that it's also present in the output file. Standardize wording
4437 in makefile copyright notices to match GNU coding standards.

4453 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4454 in the sed script that mangles the awk script: delete up to the
4455 first exclamation mark only.
4456 * tests/torture.at (Substitute and define special characters):

4461 Rewrite config files generation: avoid quadratic growth in
4462 the number of substituted variables by using awk instead of sed
4463 for the bulk of the substitutions.
4464 * NEWS: Mention this.
4465 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4466 forbidden in the output (and thus input) file.
4467 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4468 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4469 generate just one large awk script for substitutions,
4470 eliminating much of the earlier complexity, while adding some
4471 new complexity. Only expand the substitution templates at
4472 configure time, for smaller configure script size. If
4473 _AC_SUBST_FILES are used, test 'awk' for working getline support
4474 at config.status time. If absent, interpolate through the
4475 shell. The awk script was written with much help
4476 from Paolo Bonzini and Paul Eggert.
4477 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4478 (_AC_SED_FRAG_NUM): Likewise.
4479 (_AC_SUBST_CMDS): Renamed from...
4480 (_AC_SED_CMDS): ...this.
4481 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4482 * tests/torture.at (Substitute a 2000-byte string): Also
4483 substitute a line with 1000 words, and a variable with several
4485 (Substitute and define special characters): Test awk special
4486 characters, and put substitution input strings `@foo@' in the
4487 output, to test that no recursion happens; test several other
4488 combinations from Paolo Bonzini.
4490 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4492 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4493 that replaced echo with AS_ECHO where this wasn't necessary.
4494 Problem reportd by Ralf Wildenhues.
4495 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4496 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4497 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4499 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4501 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4503 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4505 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4506 that traditional Awk lacks 3-arg "split". It has it.
4507 Mention that FS must be a single character, and a few other
4508 99-byte limits of traditional Awk.
4509 Mention that if (i in a) doesn't work with traditional Awk.
4511 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4513 * tests/autotest.at (BSx641-newline in command):
4514 (BS-BS-newline in command, BSx640-newline in command):
4515 (Newline-CODE-BS-newline in command):
4516 (Single-quote-BS-newline in command):
4517 (Single-quote-newline-BS-newline in command):
4518 Use printf '%s\n' instead of echo, for portability to hosts
4519 where echo interprets backslashes. This will break on hosts
4520 that lack printf, but for now let's assume all such hosts
4521 are dead (if not, we should get reports of test failures).
4523 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4525 'echo' has some portability problems, when given a first argument
4526 with a leading '-', or when given any argument containing '\'.
4527 Avoid using 'echo' in these cases.
4528 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4529 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4530 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4531 * lib/autotest/general.m4 (AT_INIT): Likewise.
4532 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4533 argument might be unportable.
4534 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
4535 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

4551 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
4552 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4553 * bin/autoconf.as: Redo verbose flag implementation, as the old
4554 scheme wouldn't work with AS_ECHO.
4555 * lib/autotest/general.m4 (AT_INIT): Likewise.
4556 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4557 Don't use ECHO_T, since ECHO_N is now reliable.
4558 * lib/autotest/general.m4 (AT_INIT): Likewise.
4559 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4560 rather than using a here-document to put the script into a file.
4561 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4563 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4564 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4565 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4566 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4567 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4568 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4569 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4570 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4571 operand, as AS_ECHO requires. Avoid double file name expansion.
4572 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4573 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4574 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4575 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4576 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4577 Double-quote strings that would otherwise contain M4 comments.
4578 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4580 * configure.ac (AC_INIT): Bump to 2.61a.
4583 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4587 * configure.ac (AC_INIT): Bump to 2.61.
4590 * tests/autotest.at (Macro with backslash in a test title):
4591 Comment out for now, as this tests neither fails nor passes
4592 reliably. Problem reported by Ralf Wildenhues.
4594 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4596 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4597 in previous change, which caused test failures.
4599 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4601 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4602 code for --enable, --disable, --with, and --without to...
4603 (_AC_INIT_PARSE_ENABLE): ... a new macro.

4670 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4671 benefit of platforms like Solaris+GCC where it is common to have a
4672 non-working g++ installation.
4674 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4675 and Joel E. Denny <jdenny@ces.clemson.edu>
4676 and Paul Eggert <eggert@cs.ucla.edu>
4678 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4679 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4682 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4684 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4685 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4686 Imported from a similar patch to gnulib by Bruno Haible.
4688 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4690 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4701 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4703 * tests/torture.at (Configuring subdirectories): Do not skip
4704 Automake 1.10 nor future Automake 11.1 (sic).
4706 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4707 and Stepan Kasal <kasal@ucw.cz>
4709 Handle special characters in test case titles correctly.
4710 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4712 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4713 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4714 argument. Extend to check titles printed by ./micro-suite and
4715 ./micro-suite -l and the title in micro-suite.log.
4716 (Backquote in a test title,
4717 Single-quote in a test title,
4718 Double-quote in a test title): Don't expect failure anymore.
4719 (Backslash in a test title): Put a non-whitespace character after the
4720 backslash so that Bourne shells might actually see it as an escape
4722 (Brackets in a test title,
4723 Pound in a test title,
4724 Comma in a test title,
4725 Quoted Macro in a test title,
4726 Macro in a test title,

4728 (Macro with backquote in a test title,
4729 Macro with double-quote in a test title,
4730 Macro with backslash in a test title): New tests expected to fail.
4731 * tests/torture.at (#define header templates): M4-quote this title in
4732 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4733 The visible effect was a stray [] in the testsuite output.
4735 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4737 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4738 `trap ... 0' inside a function, for AIX sh.
4740 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4742 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4743 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4744 5363) simply issues a warning when dividing by zero at compile
4745 time. Problem reported by Elias Pipping.
4747 2006-10-26 Eric Blake <ebb9@byu.net>
4750 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4751 show effect on macros that expand with commas.

4765 `--force' always rewrites the output file.
4767 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4769 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
4770 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
4772 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4774 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
4776 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4778 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4779 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4780 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4781 reported by Nelson H. F. Beebe for Coreutils 6.4.
4783 * tests/tools.at (autoconf --trace: user macros): Remove test
4784 for tracing multiline macros, since m4 1.4.7a uses a different
4785 way to number lines. Problem reported by Ralf Wildenhues.
4787 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4789 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4790 /dev/null since the heuristics for interactive behaviour was
4793 * bin/autom4te.in: With --force, always refresh the output
4794 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4796 * bin/autoconf.as: Fix the verbose message at the end.
4798 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>
4800 * configure.ac (AC_INIT): Bump to 2.60c.

4815 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4816 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4844 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4846 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4847 looking for special shell characters.
4848 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4849 macro defined by AS_VAR_PUSHDEF before passing it as a

4861 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4863 (Imported from Automake.)
4864 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4865 which incorrectly sets the mode of an existing destination
4866 directory. In some cases the unpatched install-sh could do the
4867 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4868 system. We hope this is rare in practice, but it's clearly worth
4869 fixing. Problem reported by Alex Unleashed in
4870 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4871 Also, don't bother to check for -m bugs unless we're using -m;
4872 suggested by Stepan Kasal.

4880 is enabled by default with gnu and gnits strictness.
4881 Report from Bruno Haible.
4883 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4884 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4885 gnu and gnits modes.
4887 Import this change from Config:
4889 2006-09-20 Ben Elliston <bje@gnu.org>
4890 * build-aux/config.sub (score, score-*): New.
4892 Import this change from Gnulib:
4894 2006-09-16 Karl Berry <karl@gnu.org>
4895 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4896 to avoid sectioning errors.
4898 Import these changes from Texinfo:
4900 2006-10-04 Karl Berry <karl@gnu.org>
4901 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4902 (\quoteexpand): rename to \rquoteexpand.
4903 (\codequoteleft): new def, to look for @set codequotebacktick.
4904 (\lquoteexpand, \quoteexpand): new defs.
4905 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4906 (\code): must use new \...Char values, since now ` is active.
4908 2006-08-26 Karl Berry <karl@gnu.org>
4909 * build-aux/texinfo.tex (\textdegree): New command.
4911 2006-08-12 Karl Berry <karl@gnu.org>
4912 * build-aux/texinfo.tex (error \box0): smaller font.
4914 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4916 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4918 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4920 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4921 added to the template can get mangled.
4923 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4925 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4926 include the default headers, and redefine obstack_chunk_alloc

4949 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4950 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4951 Use a better substitute, by inspecting the output of "ls"
4952 rather than just using ":".
4953 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4954 rather than AS_EXECUTABLE_P, since we needn't worry about
4955 non-regular files here.
4957 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4958 due to configuration hassles with this. See Tonya Underwood's report
4959 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4986 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4987 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4989 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4990 with werror_flag and conftest.err and so forth. This is more
4991 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4992 and anyway the user shouldn't normally want to see this gorp logged.
4993 Problem reported by Ralf Wildenhues.
4994 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4995 empty, not 'no', since the rest of the code uses 'test -z'.

5006 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
5007 than creating a file to use with test -x; this is much faster.

5029 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
5030 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

5051 values. Problem reported by Ralf Wildenhues.

5266 broken lex libraries like native ia64-hp-hpux11.22; see
5267 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

5385 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
5387 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
5388 pacify insanely picky compilers. Problem reported by Eric Blake.

5391 longer supported by Sun.
5393 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
5395 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
5396 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
5397 -Wundef -Werror". Problem reported by David Fang in
5398 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
5399 * doc/autoconf.texi (Header Templates, Default Includes):

5401 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
5402 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

5414 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
5415 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
5418 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
5420 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
5421 problems with arg script text that doesn't end in newline, and
5422 with '-e a...'. Problems reported by Ralf Wildenhues.
5424 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
5426 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
5427 check for libXt by a check for libX11.
5429 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5431 * doc/autoconf.texi (config.status Invocation): Adjust according
5434 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5436 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
5437 --help' should mention that `--version' outputs configuration
5438 settings. Report by Bruno Haible.
5440 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
5442 Fix test suite failures reported by Pierre in
5443 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
5444 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
5445 the compiler created a file "b.out" when it didn't create anything
5447 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
5448 Discard stderr too, when invoking the test script.

5453 in the restoring of the werror flag.
5455 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5457 * doc/autoconf.texi (Volatile Objects): Be even a little
5458 less skeptical about "volatile", after discussion with
5459 Bruno Haible on bug-gnulib.
5460 (Limitations of Usual Tools): Warn about sed stripping
5461 leading white space from text. From Bruno Haible.
5463 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5465 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5466 compiler complains about it, even if things works after the
5467 complaint. Problem reported by Peter O'Gorman.
5469 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5470 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5471 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5473 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5475 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5476 after -R regardless of host. Patrick Welche reports that this
5477 fixes things on NetBSD 3.99.
5479 * NEWS: Recommend M4 1.4.5.

5487 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5488 under AC_C_VOLATILE.
5489 (Volatile Objects): Be a little less skeptical about what
5490 "volatile" means. Derived from thoughts by Ben Pfaff in
5491 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5493 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5495 * doc/autoconf.texi: Fix some typos.
5497 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5499 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5500 more globally, since the 2006-06-30 patch didn't suffice. Problem
5501 reported by Keith Marshall. Also, don't bother with builddir2,
5502 since it shouldn't be needed any more.
5504 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5506 * doc/autoconf.texi (Generic compiler characteristics):
5507 Document AC_COMPUTE_INT. Fix wrong statements on Default
5508 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5510 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

5521 * NEWS: Document previous change.
5523 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5525 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5526 Require that long long int be at least 64 bits wide. C99 requires
5527 this and enough programs depend on it so we should check for it.
5528 Bruno Haible reports in
5529 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5530 that long long int is 32 bits wide with some nonstandard compilers.
5531 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5533 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5535 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5536 to a nonexistent file, so that we don't have to worry about
5537 a local site configuration that doesn't use /usr/local.
5538 Problem reported by Keith Marshall in
5539 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5541 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5543 * doc/autoconf.texi: Be more consistent about using @acronym with
5544 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5545 quite right (it talked about "OSF/Tru64", even though the
5546 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5547 and it even mentioned "OSF 4"!) and at this point there's little
5548 reason to talk about OSF any more, since it died in 1994.
5549 (Specific Compiler Characteristics): Simplify example of
5550 negative-size array.
5551 (File Descriptors): Reorder to make the text flow better.
5552 Remove joke about "appreciate the various levels"; I didn't get it.
5553 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5554 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5555 (File Descriptors, Limitations of Usual Tools):
5556 Tone down the advice against renaming or removing open files.
5557 (Limitations of Usual Tools): Add a new section, on 'rm'.
5559 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5561 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5562 -lXt in LIBS, idea from Karsten Hopp; this was due since
5565 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5566 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5567 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5568 (which belong to Xt, not X itself). See Debian bug 327655.
5570 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5572 * configure.ac (AC_INIT): Bump to 2.60a.
5575 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5579 * configure.ac, NEWS: Update.
5581 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5583 * config/texinfo.tex: Sync from upstream.
5585 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5586 quadrigraph correctly in traces.
5588 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5592 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5594 * doc/autoconf.texi (Changed Directory Variables): New node,
5595 to document the whole `datarootdir' business a bit better.
5597 * tests/torture.at (datarootdir workaround): Extend test.
5598 Prompted by report by Alexandre Julliard.
5600 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5602 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5603 when using default mode of IBM C 6 for AIX. Problem and two-line
5604 fix reported by Larry Jones.
5606 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5608 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5609 about literal '${datarootdir}' if a definition is found in the
5612 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5614 * NEWS: Use "M4" rather than "m4" when appropriate.
5615 Problem reported by Eric Blake.
5616 * doc/autoconf.texi: Likewise.
5617 Use @acronym around BSD, GCC, and GNU when appropriate.
5618 (Why GNU M4): Renamed from "Why GNU m4".
5619 (Redefined M4 Macros): Mention that Posix
5620 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5621 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5624 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5626 * bin/autom4te.in (handle_output): Do not forbid the empty
5628 * tests/tools.at (autoconf: the empty token): New test.
5630 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5632 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5633 calls, so that we do not care whether they are LIFO or FIFO;
5634 in the m4_wrap, do not check which diversion is the topmost
5635 one, just check that the stack is balanced at the end.
5636 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5637 base diversion forever--pop the previous diversion before
5638 opening the new one; consequently, remove the m4_wrap call.
5639 * lib/autotest/general.m4 (AT_INIT): Likewise.
5640 * tests/m4sugar.at: Do not use
5641 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5643 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5644 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5646 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5647 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5648 Rework example of m4wrap token-pasting trouble so that it doesn't
5649 care whether it's LIFO or FIFO.
5650 Fix some "contrary to"s that are awkward in English.
5652 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5654 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5655 to `yes' instead of `int$1_t' if the type is found, for more
5656 consistent configure output (where $1 is the number of bits).
5657 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5658 Suggested by Bruno Haible.
5660 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5661 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5662 with system headers. Report by Bruno Haible.
5664 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5666 * config/config.guess, config/config.sub: Sync from upstream.
5668 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5669 in order to avoid picking up an older installed frozen m4sh.m4f.
5670 Besides an outdated shell startup, this could have been created
5671 by an earlier M4 version with incompatible frozen file format.
5673 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5675 * README: Recommend m4 1.4.4 instead of 1.4.3..
5676 * doc/autoconf.texi: Likewise.
5677 (Special Chars in Names): Say that $(.FOO) is portable, as
5678 suggested by Stepan Kasal.
5679 (Installation Directory Variables, Build Directories):
5680 (Automatic Remaking, Subdirectories, Fortran Compiler):
5681 (Making testsuite Scripts, Defining Directories):
5682 Quote variable usages better.
5683 (Making testsuite Scripts): Add clean-local rule to makefile
5684 snippet, by Eric Blake.
5685 (Installation Directory Variables): Fix table item font.
5686 Reword slightly to clarify. Generalize advice about
5687 not using special characters to include all file-related
5688 vars, not just VPATH.
5689 (Special Chars in Variables): Warn about special characters in
5691 (Assignments): Clarify default-value example as suggested by
5693 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5694 (Special Shell Variables): Note leading ./ or ../, as suggested
5696 (Limitations of Builtins): Under cd, warn about CDPATH.
5697 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5700 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5702 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5703 `@var', for texi2html.
5704 (Systemology): Some more word wrapping, for DVI output.
5705 (autom4te Invocation): The short option for `--melt' is `-M',
5708 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5710 * doc/autoconf.texi: More formatting and English tweaks,
5711 many suggested by Ralf Wildenhues.
5712 Reword to avoid "@code{...}'s" and the like, since it's ugly
5713 with Emacs info mode. discontents -> woes.
5714 Put a few "will"s back. time stamp -> timestamp.
5715 side-effect -> side effect.
5717 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5719 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5720 Warn about $@ not persisting. Problem reported by Julien Danjou in
5721 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5722 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5723 Mention other special chars, too.
5725 2006-06-14 Eric Blake <ebb9@byu.net>
5727 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5729 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5731 * doc/autoconf.texi: Some systematic minor improvements, as
5732 follows. Use "makefile" when talking about makefiles
5733 generally (which might be named "makefile" or "Makefile" or even
5734 "foo.mk"), "Makefile" when talking about a specific makefile
5735 called "Makefile". This unclutters the text from weird quotes
5736 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5737 values" rather than "@var{foo}s" and similar constructs containing
5738 "}s". Use "Make rules" rather than "Makefile rules". Minor
5739 English-language improvements. Change the prefix "sub-" to "sub"
5741 Put blank lines around examples more consistently.
5742 Avoid "rather" and "very" as intensifiers.
5743 Avoid "will" as an auxiliary.
5744 (Limitations of Make): Split this node into....
5745 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5746 (Leading _ in Macro Names, Backslash-Newline-Newline):
5747 (Backslash-Newline Comments, Long Lines in Makefiles):
5748 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5749 (obj/ and Make, make -k Status, VPATH and Make):
5750 (VPATH and Double-colon, $< in Explicit Rules):
5751 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5752 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5753 New nodes, resulting from splitup of Limitations of Make.
5754 All cross-references changed. Raise the top node from
5755 a section to a chapter, and all subnodes accordingly.
5756 Redo the introductory wording to match the new organization.
5757 (Installation Directory Variables): Use an example that is
5758 closer to what Autoconf actually does. Mention that VPATH's
5759 value should not contain metacharacters or white space.
5760 (Fortran Compiler): Fix a VPATH bug in an example.
5761 (Leading _ in Macro Names): Mention that this problem is no longer
5762 of practical concern.
5763 (VPATH and Make): Reword the advice to make it clearer
5764 that Autoconf and Automake support VPATH in non-GNU make, but
5765 many packages have bugs in this area.
5766 ($< in Explicit Rules): Refer to Build Directories rather
5767 than using a (non-VPATH-safe) example.
5768 (Automatic Rule Rewriting): Mention the sort of disaster that
5769 can ensue with Solaris-style rule rewriting with VPATH.
5771 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5773 * doc/install.texi (Compilers and Options): Weaken the
5774 suggestion to use GNU make for VPATH builds.
5776 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5777 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5779 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5780 in regular expression.
5782 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5784 * doc/autoconf.texi (Installation Directory Variables):
5785 Drop extra @samp from `@table @samp' item.
5786 (Limitations of Usual Tools): Comment fix.
5787 Do not nest @samp just to point to other table items.
5788 (Writing testsuite.at) <AT_CHECK>: The second argument to
5789 `@dvar' is already @samp'ed.
5790 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5791 do not use @var in the second argument.
5793 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5795 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5796 $as_shell.exe too. Problem reported by Andreas Buening in
5797 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5799 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5801 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5802 `unused variable' compiler warning, for `-Wall -Werror'.
5803 Reported by Jaap Haitsma in
5804 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5806 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5808 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5809 case the compiler dumps core. Problem reported for
5810 OpenServer 5.0.7 by Tim Rice in
5811 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5812 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5815 2006-06-06 Tim Rice <tim@multitalents.net>.
5817 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5818 "ERROR" only shows up in "make check" output if there is an

5823 * tests/tools.at (automatically allowed tokens): Fix typo.
5825 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5827 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5829 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5830 typically overflows on x86 CPUs, even though the C standard
5833 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5835 * configure.ac (AC_INIT): Bump to 2.59e.
5838 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5842 * config/texinfo.tex: Sync from upstream.
5844 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5845 seen, invoke libtoolize with `--ltdl' argument.
5846 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5848 Suggested by Eric Blake.

5852 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5853 reported by Ralf Wildenhues.
5854 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5856 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5860 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5862 * doc/autoconf.texi: Modernize some of the references to Solaris.
5864 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5866 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5867 message issued by AC_REQUIRE.
5868 * tests/m4sugar.at: Check m4_require's error message.
5869 * tests/base.at: Check AC_REQUIRE's error message.
5870 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5872 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5874 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5875 `expout' as the last parameter.
5876 * tests/tools.at: Adapt to the above change.
5878 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5880 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5881 information about race-free implementations of mkdir.
5883 2006-06-04 Eric Blake <ebb9@byu.net>
5885 * bin/autoreconf.in (help): Document M4 environment variable.
5886 * bin/autoconf.as (Usage): Likewise.

5890 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5892 * NEWS: GNU make now recommended for VPATH builds.
5893 Mention that some macros are now documented to be obsolescent.
5894 * doc/autoconf.texi:
5895 Prefer "current" to "modern" to describe
5896 currently-used (albeit perhaps old-fashioned) hosts.
5897 Mention which ancient features no longer need to be worried about.
5898 setgid -> set-group-ID
5899 setuid -> set-user-ID (these are the Posix terms)
5900 Fix some misuses of "only".
5901 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5902 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5903 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5904 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5905 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5906 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

5908 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5909 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5910 Mention that these macros are obsolescent.
5911 (Installation Directory Variables): shall -> should
5912 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5913 Mention that it's now safe to use 3 and 4.
5914 (Limitations of Usual Tools): cp -r is now specified by Posix.
5915 Omit longwinded and obsolescent discussion of cp -f.
5916 Modernize discussion of expr, ls.
5917 (Limitations of Make): Modernize discussion of VPATH builds.
5918 Mention $? as a workaround in some cases.
5919 * doc/install.texi (Basic Installation):
5920 Mention "./configure; make; make install" first. Be more
5921 specific about why this file is generic. Remove unnecessary
5922 parens. Remove misleading "only". Remove obsolete advice
5923 about csh. Don't say "configure" takes awhile; say it
5924 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5925 and CC=c99 rather than CC=c89, as these are blessed by current
5926 Posix. Recommend GNU make if doing a VPATH build.
5928 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5930 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5931 examples involving shell prompts.
5933 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5934 and Paul Eggert <eggert@cs.ucla.edu>
5936 * doc/autoconf.texi (Here-Documents): Add details about the
5937 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5938 use "here-documents" instead of "here documents".
5940 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5942 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5944 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5946 * doc/autoconf.texi (File System Conventions): Warn about ":"
5947 anywhere in directory names.
5949 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5951 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5952 about quoting the case statement, just in case.
5953 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5954 was fixed in ksh93g; reported by Ralf Wildenhues.
5956 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5958 * doc/autoconf.texi (System Services): Do not document
5959 overriding EXEEXT via ac_cv_exeext=ext.
5960 (Particular Programs) <AC_PROG_MKDIR_P>:
5961 Document that ${MKDIR_P} understands --.
5962 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5965 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5967 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5968 argument with leading hyphen. Problem reported by Paul Eggert.
5970 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5972 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5973 about quoting ac_try: quote all of it, if any of it seems suspicious.
5974 This means we don't have to worry about ${ or sed any more.
5975 Also, double-quote the case statement, to work around misuses via
5976 underquoting as reported by Ralf Wildenhues in
5977 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5978 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5979 undocumented and dangerous macro.
5980 Problem reported by Ralf Wildenhues in
5981 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5983 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5985 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5986 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5987 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5989 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5991 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5992 since evidently some packages rely on the old, broken behavior.
5993 Problem reported by Ralf Wildenhues in
5994 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5995 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5996 pre-2006-05-26 definitions, but leave in the comments that
5997 these macros are dangerous and should not be used.
5998 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5999 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
6000 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
6001 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
6002 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
6004 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
6006 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
6007 the use of 'tr', since this is our only use of 'tr'.
6009 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6010 and Paul Eggert <eggert@cs.ucla.edu>
6012 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
6013 Don't assume 'grep' works on long lines, since AIX grep doesn't.
6015 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6017 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
6018 the output file in the `${datarootdir}' test.
6020 2005-05-28 Stepan Kasal <kasal@ucw.cz>
6021 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6023 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
6024 mention of `datarootdir' in the input file(s), but literal
6025 `${datarootdir}' in the output file, and we haven't warned yet,
6026 then warn as well: the user may have (erroneously) used
6027 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
6028 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
6029 * tests/torture.at (datarootdir workaround): Extend this test.
6032 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6033 and Paul Eggert <eggert@cs.ucla.edu>
6035 * doc/autoconf.texi (autoheader Invocation): The first argument to
6036 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
6037 alternatives and clear up the language a bit.
6039 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
6041 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
6042 ac_config_guess, ac_config_sub, ac_configure.
6043 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6044 Fix typo that prevented an unnecessary space from being removed.
6045 Problems reported by Ralf Wildenhues in:
6046 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
6048 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6050 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
6051 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
6052 Don't use the term "thread-safe" to talk about mkdir race
6053 conditions, since the problem is more a process than a thread
6054 issue. Problem reported by Stepan Kasal in:
6055 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
6056 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
6057 the test for 'install' more closely. Look at MKDIR_P first.
6058 Look in the PATH, and at /opt/sfw/bin.
6059 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
6060 Don't bother to try mkdir -p, since we already check mkdir --version;
6061 just look at the version number. (There's no easy way to check
6062 for race-free implementations.)
6063 * tests/tools.at (autoconf: subdirectories): Adjust to above
6064 changes, since MKDIR_P now might end in "/mkdir -p".
6066 * doc/autoconf.texi (autoheader Invocation): Mention that the
6067 first arg of AC_DEFINE_UNQUOTED must be a literal.
6068 Problem reported by Ben Pfaff in
6069 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
6071 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
6072 * doc/autoconf.texi (Special Chars in Variables): New section.
6073 (Preset Output Variables): Warn about special chars in CPPFLAGS.
6074 (Installation Directory Variables): Quote $(datadir) better.
6075 (Limitations of Builtins): Describe some of eval's trickiness.
6077 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
6078 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
6079 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
6080 in front of every arg, not just trailing args. Quote apostrophes.
6081 (_AC_EVAL_ECHO): New macro.
6082 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
6083 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
6085 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
6086 exposed by quoting of eval argument. Put the command on line line
6088 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
6089 (_AC_PATH_X, AC_PATH_X): Quote more safely.
6090 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
6091 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
6092 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
6093 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
6094 Use eval more safely.
6095 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
6096 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
6098 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
6099 lines, exposed by quoting of eval argument.
6101 2006-05-26 Stepan Kasal <kasal@ucw.cz>
6102 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6104 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
6105 initialization of `ac_cv_exeext', do not override it if it was
6106 already set, unless it was set to `no', for compatibility with
6107 Autoconf-2.13, and comment this.
6108 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
6109 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
6110 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
6111 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
6112 Document that this test may be overridden by setting
6115 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6117 Revert these two patches:
6119 2006-04-06 Eric Blake <ebb9@byu.net>
6120 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6121 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6124 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6125 Clean up _AC_COMPILER_EXEEXT* macros.
6126 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6127 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6128 ac_file to the name of the default output file and call
6129 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6130 initial `rm' of the candidate files...
6131 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6132 the same list in subsequent `rm' calls, and for the temporary
6133 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6134 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6135 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6136 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6137 no longer needed) by libtool. Make it a cache check.
6138 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6139 copied here by mistake.
6140 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6141 _AC_COMPILER_EXEEXT.
6142 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6143 _AC_COMPILER_OBJEXT directly.
6144 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6146 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6148 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6149 Fix description of how the buggy `sed' works.
6151 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6155 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6156 ENOLCK. Only mention `make -j' when applicable. Only raise
6157 fatal errors when `make -j' is involved. Improve error message.
6159 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6161 * doc/autoconf.texi (Here-Documents): We now know more about
6162 the variable expansion in here documents bug.
6163 Thanks to Tim Rice and Stepan Kasal.
6165 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6166 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6168 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6170 * tests/autotest.at (Multiline command from M4 expansion):
6171 No failure to be expected if the shell quotes newlines in
6172 commands in the `set -x' output. Report by Tim Rice.
6175 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6177 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6178 expansion in the here-documents used by config.status, as that
6179 runs afoul of the Korn shell version M-12/28/93d bug described in
6180 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6181 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6182 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6184 2006-05-23 Jim Meyering <jim@meyering.net>
6186 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6187 Fix typo introduced with 2006-04-02 change. It reversed the sense
6190 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6192 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6193 ac_dB slightly, to save bytes in the script.
6194 Max out at 50 lines, rather than 96; this is more likely
6195 (though not guaranteed) to avoid obscure 'sed' failures.
6197 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6199 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6200 `tr -d -' as bad option argument. Work around this by deleting
6201 an unrelated character.
6202 Report by Tim Rice <tim@multitalents.net>.
6204 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6205 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6206 Stepan Kasal <kasal@ucw.cz>
6208 * doc/autoconf.texi (Particular Programs): Do not promise that
6209 we always prefer the GNU version of the program, and that we
6210 search according to PATH; both rules can have exceptions.
6211 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6212 AC_PROG_SED. Move descriptions of limitations
6213 to the Limitations of Usual Tools section.
6214 (Limitations of Usual Tools) <sed>: Mention script length
6215 limitations with Solaris /usr/ucb/sed.
6216 <grep>: Fix wording for empty alternative. Mention that -c and
6217 -l should not be combined, and that -E and -F should not be
6220 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6221 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6223 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6224 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6226 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6228 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6229 AC_DEFINE is now passed to m4_pattern_allow.
6230 * NEWS: Mention that; likewise for AC_SUBST.
6231 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6232 the parameter to m4_pattern_allow.
6233 * tests/tools.at: Add a check for that.
6235 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6237 * lib/autoconf/status.m4: Fix typos.
6239 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6241 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6242 only the files that this macro generates.
6244 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6246 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6247 the HP-UX sed limitation of 99 commands, labels do not count.
6248 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6250 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6252 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6254 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6255 Import the following fix from coreutils:
6257 2006-01-13 Jim Meyering <jim@meyering.net>
6259 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6260 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6261 not double-quote uses of that variable, to accommodate the rare
6262 case in which getmntent is available in none of the libraries
6263 checked. This happens at least on FreeBSD 5.0.
6265 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6267 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6268 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6269 some other programs unwisely rely on these undocumented vars.
6270 But put in warning comments about them.
6271 Problem reported by Ralf Wildenhues in
6272 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6273 * NEWS: Document that these variables are intended to go away.
6275 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6277 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6278 and set the language to C++ (analogous to the equivalent Fortran
6281 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6282 * doc/autoconf.texi (C++ Compiler): Document it.
6283 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6286 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6288 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6289 that caused config.status to generate 100-command sed scripts; the
6290 portable limit is 99.
6292 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6294 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6295 variable `ac_d' instead of `d' to avoid infringing namespace.
6296 Report by Ralf Menzel.
6298 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6300 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6301 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6302 * tests/tools.at (autoconf: subdirectories): New test, taken from
6303 the corresponding problem report by Ralf Wildenhues in:
6304 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6306 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6307 Quote some uses of shell variables if they might suffer unexpected
6308 globbing. This doesn't fix all instances of quoting problems that
6309 I found, just the easy ones that look safe.
6310 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6311 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6312 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6313 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6314 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

6318 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6319 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6321 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6323 * bin/autoreconf.in ($help): Reword according to the manual.
6324 Suggested by Olly Betts.
6326 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6327 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6329 * bin/autoreconf.in: Pass the directory argument to
6330 `require_configure_ac'. Fix comment.
6331 * tests/torture.at (Configuring subdirectories): Expose this.
6332 Reported by Olly Betts.
6334 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6336 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6337 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6338 Automake as follows:
6340 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6341 `$configure_in' instead of `configure.in', to preserve
6342 directory component.
6344 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6346 * config/config.guess, config/config.sub, config/texinfo.tex,
6347 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6349 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6351 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6352 test for C99 conformance; (bool) 0.5 is an integer constant
6353 expression, but (bool) -0.5 is not. Problem reported by Fedor
6354 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6356 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6358 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6359 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6360 Warn about obsolete install-sh files. Remove stray sentence
6361 fragment and fix cross reference.
6362 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6363 install -d; this undoes the 2006-05-10 change.
6364 (MKDIR_P): Mark with AN_MAKEVAR.
6365 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6366 that we don't require $INSTALL to be thread-safe. Move comments
6367 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6368 of AC_PROG_INSTALL. Output a message saying that we're checking
6369 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6370 MKDIR_P instead of AC_SUBST.
6371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6372 Special magic for MKDIR_P, too.
6373 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6375 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6377 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6379 Sync from Automake, as follows:
6381 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6382 * config/install-sh: Initialize IFS, so field splitting isn't
6384 * config/mkinstalldirs: Likewise.
6385 * config/missing: Remove superfluous quotes. Replace all uses of
6386 `[' by `test', for consistency, and for..
6387 * config/missing (sed_minuso, sed_output): New variables.
6388 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6389 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6390 Fixes `missing' to detect `--output' for help2man. Fixes
6391 PR automake/483. Report by Dennis J. Linse.
6392 (autom4te): Document in `missing --help'.
6394 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6396 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6397 * config/install-sh: Don't use 'path' to talk about file names,
6398 as per GNU coding standards. Close a race condition reported by Ralf
6399 Wildenhues and Stepan Kasal. There is still a race condition
6400 on hosts that predate Posix 1003.1-1992, but we can't help this.
6401 Don't mishandle weird characters like space on pre-Posix hosts.
6402 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6403 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6404 AC_PROG_MKDIR_P from AS_MKDIR_P.
6405 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6406 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6407 earlier editions are not (including Automake 1.8.3).
6408 Do not suggest mkinstalldirs for thread-safety.
6409 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6410 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6411 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6412 presence of special characters and race conditions.
6413 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6414 in Autoconf's name space.
6416 2006-05-10 Bruno Haible <bruno@clisp.org>
6417 and Paul Eggert <eggert@cs.ucla.edu>
6419 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6420 from Automake with minor changes.
6421 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6423 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6425 * config/install-sh: Update to Automake CVS version, as follows:
6426 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6427 * lib/install-sh: Simplify the expr implementation of dirname.
6428 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6429 * lib/install-sh: Handle --, and diagnose unknown options.
6431 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6433 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6434 `./autom4te' to create `./testsuite', since the `all' target
6435 will ensure its presence, but `installcheck' should not create
6436 the uninstalled wrappers.
6438 * tests/torture.at (Unusual Automake input files): Skip if we
6439 detect automake < 1.8.
6441 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6443 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6444 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6445 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6448 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6450 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6451 munge (multiple) white space and other oddities.
6452 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6453 single quotes in variable assignment.
6454 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6455 and similar failures by adding multiple spaces, tabs, and other
6457 Report and different test suggested by Francesco Romani
6458 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6460 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6461 single quotes, we only need to search for single quotes; this
6462 both simplifies the search pattern, and makes us less
6463 susceptible to `echo' variations for arguments not containing
6465 (_AC_ARG_VAR_VALIDATE): Likewise.
6467 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6469 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6470 `$*' and IFS concatenation issue with traditional shells and
6471 bash-2.04. Report by Seanster@Seanster.com.
6473 2006-05-03 Bruno Haible <bruno@clisp.org>
6475 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6476 precisely which Mac OS X versions have the od problem.
6478 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6480 * doc/autoconf.texi: Use @option systematically.
6482 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6483 and Bruno Haible <bruno@clisp.org>
6485 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6487 (Integer Overflow): Mention the special case of integer division
6490 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6492 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6493 traditional shells like the Solaris one that do not use the
6494 first IFS character for assembling `$*'.
6495 Prompted by a related report from autoconf_bug@nro.ca.
6497 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6498 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6500 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6501 Mention more problems with the -e option.
6503 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6506 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6508 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6509 in URLs to improve DVI formatted output (requires texinfo 4.6).
6510 (System Services, Systemology, Shellology): Likewise.
6511 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6514 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6516 (Runtime): Fix macro argument names to match description:
6517 `action-if-found' -> `action-if-true' and similarly.
6518 (Obsolete Macros): Likewise.
6519 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6520 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6521 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6523 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6525 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6528 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6531 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6533 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6534 /bin/sh set unsorted output.

6541 (Integer Overflow, Null Pointers, Buffer Overruns):
6542 (Floating Point Portability, Exiting Portably): New sections.
6543 (Writing Test Programs): Fix some langauge. Recommend exiting
6544 with status 1, not merely nonzero. Clarify exit declaration.
6545 (Run Time): Move C exit status stuff to new Exiting Portably section.
6546 (Systemology): Mention Posix and levenez. Update v7 reference.
6547 (Portable Shell): Mention the Posix shell.
6549 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6551 * bin/autoconf.as (me): Replace by as_me.
6553 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6555 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6556 since as_me isn't set yet.
6558 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6560 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6561 a few minor bugs in this area.
6563 * doc/autoconf.texi (Programming in M4sh): Comment out the
6564 documentation of AS_BASENAME, for now.
6565 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6566 (Limitations of Builtins) <basename>: Do not refer to
6568 * bin/autoconf.as (me): Don't use AS_BASENAME.
6569 (dir): Remove the unused variable.
6570 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6571 AS_DETECT_REQUIRED. All uses changed.
6572 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6574 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6575 (AS_BASENAME): Use "basename --" to protect against leading "-".

6577 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6578 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6579 (_AS_DIRNAME_PREPARE): Likewise.
6580 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6581 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6582 (AS_DIRNAME): Use "dirname --".
6584 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6586 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6587 of "run time" and "run-time" changed to "runtime", for consistency.
6588 * lib/autoconf/fortran.m4: Likewise (in comment).
6589 * lib/autoconf/functions.m4: Likewise.
6590 * lib/autoconf/general.m4: Likewise.
6591 * lib/autoconf/headers.m4: Likewise.
6593 * doc/autoconf.texi (Run Time): Document the exit status situation
6594 with more accuracy and detail.
6596 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6598 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6599 Archive is not officially `GNU' any more. Update URL.
6600 (Defining Directories): Likewise
6601 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6603 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6605 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6606 newline from the `trap' code to finish `config.log'; the NetBSD
6607 /bin/sh resets the exit status after an empty command, as
6608 documented in doc/autoconf.texi.
6609 Reported by Dalibor Topic <robilad@kaffe.org>.
6611 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6613 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6614 Suggested by Bruno Haible.
6616 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6618 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6619 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6620 Instead, just list the shells that we know work.
6621 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6622 changed. Be more cautious about the _cv_ variable.
6623 * tests/tools.at (Syntax of the shell scripts): Check the
6624 _cv_ variable once, at first, to avoid an internal autoconf error
6625 when sh -n does not work.
6627 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6629 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6631 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6633 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6634 use ">&-" since we're only 99.999% sure that this is portable,
6635 and since the MinGW bug is fixed in a different way.
6636 * lib/autotest/general.m4 (AT_INIT): Likewise.
6638 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6640 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6641 before opening config.log, to avoid hitting a bug on MinGW.
6643 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6645 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6646 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6647 This works around a MinGW bug reported by Eric Paire.
6648 Make sure that all writes to the log file append to it,
6649 rather than possibly losing data.
6650 * lib/autotest/general.m4 (AT_INIT): Likewise.
6652 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6654 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6657 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6661 * configure.ac (AC_INIT): Bump to 2.59d.
6663 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6667 * Makefile.maint (news-date-check): Do not require a leading `*'
6668 before the release date in NEWS.
6670 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6671 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6673 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6674 the instantiated file do not contain the string 'datarootdir'
6675 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6676 @mandir@, replace the reference '${datarootdir}' by the value.
6677 * tests/torture.at (datarootdir workaround): New test.
6678 * NEWS: Advertise this temporary fixup.
6679 Based on a patch by Bruno Haible, reported and analyzed by
6680 Paul Eggert and Noah Misch.
6682 2006-04-12 Eric Blake <ebb9@byu.net>
6684 * tests/autotest.at (Debugging a failed test): Fix comment.
6686 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6688 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6689 all the changes since 2006-04-07.
6691 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6693 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6694 succeeded, but `ln -s file dir' failed, take care to remove the
6695 leftover target before the next test, to prevent its spurious
6696 failure; also make sure `ln file dir' works before selecting it.
6697 Thanks to Keith Marshall for pointing this out.
6700 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6701 assignments in `at_debug_args', so that we put them correctly
6702 in the `run' script.
6703 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6704 Reported by Eric Blake.
6706 2006-04-11 Eric Blake <ebb9@byu.net>
6708 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6709 top-level tests after micro-suite has been run. Used in...
6710 (Debugging a successful test, Debugging script and environment),
6711 (Debugging a failed test): ...these new tests. The first of these
6713 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6714 macro, split out from...
6715 (AT_INIT): ...here, so that using -d also generates a run script.
6716 Document that -d inhibits top-level logging.
6717 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6718 inhibits top-level logging; debug scripts are created.
6720 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6722 * tests/autotest.at (Empty test, Empty check): New test to check it.
6724 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6727 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6729 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6730 the files if a problem appears. Make the empty *.at files
6731 read-only, too. Proposed by Ralf Wildenhues.
6733 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6735 * config/Makefile.am: Add comment to force updated Makefile.in.
6737 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6738 space only patch to this file, this patch causes the Makefile.in
6739 files that include freeze.mk to be updated, and thus have a
6740 newer time stamp again, which in turn makes a pristine CVS
6741 checkout have correct time stamps.
6743 * Makefile.maint (cvs-sv): New macro, to be used..
6744 (config.guess-url_prefix, config.sub-url_prefix)
6745 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6746 point to CVS text checkout of Gnulib files.
6747 (copyright-check): Bump current year.
6748 (announcement): Do not hard-wire `./announce-gen'.
6749 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6751 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6753 (wget_files): Update config.guess, config.sub, texinfo.tex by
6754 `wget-update', now that their URLs work again.
6756 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6758 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6759 Problem noted by Paul D. Smith.
6761 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6763 * doc/autoconf.texi: Remove unused words from word list.

6772 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6773 with a target directory; it's internally implemented as `cp'
6774 anyway, but since Autoconf advertises the possibility to use
6775 a target directory when LN_S is `ln -s', we need to find out.
6776 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6777 analyzed by Keith Marshall <keith.marshall@total.com>.

6799 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6800 apostrophe within a single-quoted string, as this is the usual
6801 tradition and is easier to read than '"'"'. Don't rely on the
6802 shell treating "$/" like '$/'. Use a more-consistent indenting
6805 2006-04-09 Eric Blake <ebb9@byu.net>

6891 Revert the patch from 2006-04-01 and only improve
6892 _AS_DETECT_BETTER_SHELL:
6894 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6895 skip nonexistent directories.
6896 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6897 only shell candidates which exist.
6898 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6899 * lib/autotest/general.m4 (AT_INIT): No need to give three
6900 parameters to _AS_PATH_WALK.

6908 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6909 test case by Noah Misch <noah@cs.caltech.edu>.

6922 * doc/autoconf.texi (Programming in M4sh): Document that
6923 AS_MKDIR_P exits the script on failure.
6924 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6926 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6945 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6947 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6948 whether `set' quotes correctly: redirect stderr of the tested
6949 `set', and use a subshell, for Ultrix; use `sed' instead of
6950 `grep' for zsh `set' which may write binary output; match only
6951 at the beginning of a line, to avoid false positives.
6952 In order to avoid false positives by unrelated variables with
6953 multiline content, put the dump algorithm in a subshell and
6954 unset all variables containing newlines (except some which are
6955 special to the shell). Warn about cache variables that are

7001 ac_config_<foo>s again, sometimes normalized, sometimes not.
7002 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

7004 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
7005 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
7006 2005-07-25 rewrite. Noticed by Noah Misch.
7008 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
7009 _AC_PRESERVE_HELP_ORDER, ...

7016 for --help from Cygnus `configure.'
7018 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

7063 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
7065 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
7066 Use simplified args that Eric Blake originally suggested.
7068 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
7070 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
7071 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
7072 Use 'comm' rather than N instances of grep; this also fixes a bug

7074 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
7075 (exclude_list): Exclude empty macros.
7076 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

7159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
7160 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
7161 ac_file to the name of the default output file and call
7162 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7163 initial `rm' of the candidate files...
7164 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7165 the same list in subsequent `rm' calls, and for the temporary
7166 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,

7168 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7169 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7170 no longer needed) by libtool. Make it a cache check.
7171 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
7172 copied here by mistake.

7948 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7949 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7950 by the function rather than ignoring it.
7951 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7952 comparing its address. Intel's interprocedural optimization was
7953 outsmarting the old heuristic. Problem reported by

7967 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7968 before removing it (chmod -R u+rwx); there are three instances of this.

7971 Stepan Kasal <kasal@ucw.cz>
7973 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7974 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7975 make its content writable before removing it. Remove an errorneous
7976 comment from the end, where the logs of the failed tests are copied
7977 to the main log file.
7979 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7981 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7982 in case the computer is too quick. Double quote the configure.ac

7986 problems if the testsuite were running too fast.
7988 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7990 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7991 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7992 (which belong to Xt, not X itself). See Debian bug 327655.
7993 * NEWS: Mention this.
7995 2005-09-07 Stepan Kasal <kasal@ucw.cz>

8002 suggested by Ben Elliston. Handle weird characters correctly.
8004 2005-09-06 Stepan Kasal <kasal@ucw.cz>
8006 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
8007 calls, so that the final expansion of this macro is shorter.
8008 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
8009 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
8010 the cleanup there. Use AS_VAR_* macros, to be more general.
8011 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
8013 * lib/autoconf/general.m4: Use AS_IF where appropriate.
8015 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
8017 2005-09-01 Stepan Kasal <kasal@ucw.cz>
8019 * doc/autoconf.texi (Configuration Headers): Add an index entry

8030 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
8031 The previous patch didn't work, so try a better one.
8033 2005-08-26 Stepan Kasal <kasal@ucw.cz>
8035 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
8036 in the example. Reported by Bruno Haible.
8037 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
8038 "if $undefined_var;" succeeds with my shell.
8040 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
8041 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
8042 but change the m4_divert_text to m4_divert_once.
8044 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
8046 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
8047 Work around bug in Solaris /usr/xpg4/bin/awk.
8048 The bug is present in at least Solaris 8 through 10.
8050 2005-08-24 Stepan Kasal <kasal@ucw.cz>
8052 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
8053 some evil values and relying on the fact that $* concatenates the
8054 parameters by the first character from IFS.
8056 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8057 Stepan Kasal <kasal@ucw.cz>

8060 first header appears, define AH_HEADER.
8061 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
8062 Update limitations about when to call AC_CONFIG_HEADERS.
8063 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
8064 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
8065 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
8066 ``Configuration Actions''; fix their index entries.
8068 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
8069 options correctly. Process N-M as M-N if M is smaller than N.
8070 Process ranges correctly so that N-N will run only N.
8071 Sort and uniquify the tests that will be run. If there is more
8072 than one test, reinsert the banners for the tests.
8073 * tests/autotest.at (Keywords): Unmark XFAIL.
8075 2005-08-23 Stepan Kasal <kasal@ucw.cz>
8077 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
8078 before passing the macro name to AH_TEMPLATE.
8080 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
8081 now opens log after option processing; in particular, --version
8082 and --help do not touch config.log.
8084 * Makefile.maint: Revert the change from 2005-08-12.
8086 2005-08-22 Stepan Kasal <kasal@ucw.cz>

8090 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
8092 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8094 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
8095 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
8098 * doc/autoconf.texi (Defining Symbols, Changed Results):
8099 Prepend to LIBS, not append, in examples.
8101 2005-08-16 Stepan Kasal <kasal@ucw.cz>
8103 When building in place, set srcdir="."; suggested by Tim Van Holder.
8105 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
8106 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
8107 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
8108 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
8109 does not mean "no --srcdir option".
8111 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8113 * tests/autoscan.at (autoscan): New file.
8114 * tests/suite.at: Use it.
8115 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
8116 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
8118 * tests/autotest.at (Keywords): Test keywords combinations.
8120 2005-08-12 Stepan Kasal <kasal@ucw.cz>
8122 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8123 add "2>&1"; gzip 1.2.4 prints help on stderr.
8125 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8127 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8128 was pushdef'ed twice while popped only once. Push it only once.
8129 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8131 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8133 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

8138 * Makefile.maint: Update from Bison.
8140 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8141 "<tab>" in comment, so that the point is understandable.
8143 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8145 Rewrite substantial part of lib/autoconf/status.m4.
8146 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8147 and CONFIG_COMMANDS are not processed in four separate loops.
8148 Instead, there is one main loop. This alows that the common code
8149 is expanded only once, thus config.status (and configure) is smaller.
8151 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8152 the AC_LIST_FILES and cousins macros are no longer used.
8154 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8155 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8156 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8157 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer

8187 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,

8205 parameter to AC_DIAGNOSE.
8206 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8207 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8208 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8209 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8211 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

8240 (AC_ARG_VAR): ... here.
8241 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and

8304 sed substitution command, so that we allow | in program prefixes
8305 and program suffixes. (& is a problem anyway; we're not fixing
8307 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8308 configure_input, top_builddir, srcdir, etc.
8309 * lib/autotest/general.m4 (AT_INIT): Likewise, for

8320 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

8371 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8372 (AC_SUBST): Call it.
8373 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8374 the directory specific variables; but don't call it for configure_input.

8378 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8381 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8383 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

8401 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8402 variable into diagnostic. Make the diagnostic an error, not a warning,
8403 because we really don't support spaces and suchlike in dir names.
8404 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8405 Don't worry about backslashes in srcdir; it can't happen now.

8434 (Special Shell Variables): Fix sed code this in the example.
8435 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8436 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

8449 * doc/autoconf.texi:
8450 Don't mention Solaris versions so much, if a
8451 problem is common to all extant versions of Solaris. Say "SunOS
8452 4" instead of "SunOS" for SunOS 4.
8453 (awk): Mention more of the limitations of traditional Awk.
8454 (cat): Don't talk about cat -v.

8496 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8497 -u, since it outputs chatter if the input files are the same.
8498 Problem reported by Ralf Menzel.
8500 2005-06-08 Derek Price <derek@ximbiot.com>
8502 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8503 renaming them since they are about to be redefined anyhow.
8505 2005-06-08 Derek Price <derek@ximbiot.com>
8507 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8508 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8509 Move m4_undefine to alphabetical order.

8514 * doc/autoconf.texi (Introduction): Likewise.
8515 Reword to avoid some formatting glitches.
8516 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

8518 Redo example output tp match current CVS snapshot.
8519 Use @example.org in email addresses when the examples
8520 might get inadvertently cut-and-pasted into user code.
8521 Remove example of autom4te usage that doesn't seem to work now.
8522 Use modern AC_INIT (except when the example is meant to be

8537 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8538 Tru64 ksh pattern matching bug. Reported against Libtool by
8539 Albert Chin <libtool@mlists.thewrittenword.com> and
8540 Nicolas Joly <njoly@pasteur.fr>.
8542 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8544 m4_cdr of one-member list was [[]] (one-member list containing an
8545 empty string) instead of [] (an empty list. Callers were skewed to
8546 match this misbehaviour. As a consequence of this:
8547 - m4_foreach([x], [], [foo]) expanded to `foo', while
8548 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8549 This bug has been fixed:
8551 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8552 expand to an empty string; print error msg if called without
8554 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8555 misbehaviour; handle [] and [[]] correctly.

8565 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8566 swallow records with more than 99 fields.
8567 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8568 parse the long line.
8570 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8572 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8573 swallow literals longer than 399. Reported by Ralf Wildenhues.
8574 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

8579 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition

8607 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8608 now contain newlines, and substituted files must be referenced on
8609 a line alone; the sed scripts to substitute them are now very

8612 commands can be put in a sed script portably.
8613 * doc/autoconf.texi (Setting Output Variables): Document above

8616 * tests/torture.at: No longer expect substitution of newline to fail.
8618 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
8620 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
8621 From Ralf Menzel (trivial change).
8623 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8625 * tests/local.at: Don't attempt to check for negated character
8626 classes in shell scripts. The test was too brittle.
8628 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8630 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8631 * doc/autoconf.texi (Limitations of Builtins): Document this
8634 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8636 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8637 common code; used in many places in the tree.
8638 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
8639 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8641 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
8643 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
8644 messages when ac_unique_file is not found.
8645 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8646 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8647 commands, for consistency with AC_MSG_ERROR and such.
8649 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8651 * bin/Makefile.am: Merge the two rules for creating scripts.
8653 2005-05-23 Stepan Kasal <kasal@ucw.cz>
8655 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
8656 obsolete; it was never documented.
8657 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
8659 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8661 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8662 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8663 (ac_top_builddir): ... this ...
8664 (ac_top_build_prefix): ... to this; the old name is also kept, for
8665 backward compatibility.
8666 (ac_top_builddir_sub): New variable, without the trailing slash,
8668 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8669 * doc/autoconf.texi (Configuration Actions): Rename
8670 ac_top_builddir to ac_top_build_prefix.
8671 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8672 at_top_builddir to at_top_build_prefix.
8673 * lib/autotest/general.m4 (AT_INIT): Likewise.
8675 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8677 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
8680 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8682 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8683 argument to m4_foreach. I guess it was necessary in the past,
8684 but I think it's a no-op now.
8686 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8688 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8689 ``cat <<_ACEOF'' commands to one.
8690 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8691 * lib/autoconf/status.m4: On various places, use expr instead of
8693 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8694 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8695 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8697 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8698 the wrong patterns between ``case'' and ``esac.'' The previous
8699 code had false positives.
8701 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8703 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8705 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

8746 2005-05-13 Stepan Kasal <kasal@ucw.cz>
8748 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
8750 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
8751 enough arguments, similarly as in m4_bpatsubsts.
8753 2005-05-12 Stepan Kasal <kasal@ucw.cz>
8755 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
8758 2005-05-11 Stepan Kasal <kasal@ucw.cz>
8760 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
8761 for absolute directory names in one loop.
8762 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
8763 abbreviations of --version and --debug.
8765 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
8767 * doc/autoconf.texi (Autoconf Language): Be more precise about
8768 quoting rules. Problems noted by Stepan Kasal.
8769 Also, throughout this document, be more careful about white space.
8770 "blank", "white space", and "space" all have different meanings
8771 and we should be careful to say what we mean.
8773 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8775 Fix C++ related problems reported by Werner Lemberg.
8776 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
8777 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
8778 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
8779 avoid problems with C++ and throw.
8780 * tests/compile.at: .cpp, not .cc.
8782 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8784 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8786 * doc/autoconf.texi (Generic Functions): Typos.
8788 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8790 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8791 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8792 set by latest automake.
8794 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8796 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8797 outputs 0 on GNU/Linux these days.
8799 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
8801 * doc/autoconf.texi (Autoconf Language): Add more description
8802 about quoting heuristics.
8803 (Limitations of Builtins): Describe "set -" problems.
8805 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8807 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8810 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8811 by AC_DEFINE; it was a mistake.
8812 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8814 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8816 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8818 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8820 * doc/autoconf.texi (External Software): Quadrigraphs are not
8821 processed correctly in AS_HELP_STRING; avoid this in the examples.
8822 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8823 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8824 comment and reduce m4_default([foo], []) to [foo].
8825 (m4_strip): Update the explanation.
8827 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8829 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8830 Remove core.conftest.* too; it's generated by Tru64 5.1.
8831 Problem reported by Jennis Pruett.
8832 * lib/autoconf/functions.m4
8833 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8834 Don't bother to remove core files; AC_RUN_IFELSE should do that
8837 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8839 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
8841 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
8843 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
8844 Report from Horst Wente.
8846 2005-04-15 Stepan Kasal <kasal@ucw.cz>
8848 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
8851 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
8853 * doc/autoconf.texi (External Software, Package Options): Add
8854 examples showing how to implement --with-* and --enable-* options.
8856 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8858 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8859 as well as configure.in. Problem reported by Gregorio Guidi.
8861 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8863 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8864 pattern for alloca snippet.
8866 2005-04-04 Stepan Kasal <kasal@ucw.cz>
8868 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

8874 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8876 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8877 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8879 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8881 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8882 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8883 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8884 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8885 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8887 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8889 * NEWS: The configure command now warns you if you attempt to use
8890 a directory whose name contains a special character like space,
8892 * doc/autoconf.texi (Installation Directory Variables): Allow
8893 "," in file names. Do not use \@; it's not a portable regexp.
8894 * bin/Makefile.am (edit): Likewise.
8895 * lib/Makefile.am (edit): Likewise.
8896 * tests/Makefile.am (edit): Likewise.
8897 * tests/semantics.at: Likewise.
8898 * tests/torture.at: Likewise.
8899 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8900 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8901 * doc/autoconf.texi (File System Conventions): Warn about
8902 unportable file names.
8903 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8905 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8906 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8907 ac_pwd, and quote srcdir.
8908 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8910 * doc/autoconf.texi: Fix some systematic formatting problems.
8911 ".)" needs a following @: if not at the end of a sentence, and
8912 similarly for "!)". "etc." should be preceded by a comma.
8913 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8915 2005-03-22 Bruno Haible <bruno@clisp.org>
8917 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8918 argument is often called 'build-aux'.
8920 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8922 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8923 macro AC_TRY_LINK is obsolete.
8924 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8927 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8929 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8930 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8931 from a Common Lisp's `cl'.
8932 (AC_PROG_CXX): Behave according to the documentation: don't
8933 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8934 make the variable CCC precious; use `cl.exe', not `cl'.
8936 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8937 Alexandre Duret-Lutz <adl@gnu.org>
8939 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8940 /dev/null, as "configure" shouldn't read stdin, and this insulates
8941 us from problems (e.g., when testing for "cl"). Also, do this
8942 redirection before invoking "hostname" or "uname", and keep the
8943 original input stream available via...
8944 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8945 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8946 bother with "</dev/null" since it's now done at the top of
8948 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8949 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8950 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8951 * doc/autoconf.texi (File Descriptor Macros): New section.
8952 (Printing Messages): Mention it.
8953 * tests/base.at (Input/Output): New test.
8955 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8957 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8958 newline if neither \c nor -n work, as that would output two
8959 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8961 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8963 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8964 This causes that any required macros inside will get before the if.
8965 * doc/autoconf.texi (autom4te.cache): A typo.
8967 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8969 Undo previous change, except keep the change to
8970 lib/autoconf/programs.m4 that replaced grep with shell
8971 pattern-matching. This is because net-snmp configure reads stdin.
8972 Reported by Noah Misch.
8974 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8976 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8977 from /dev/null, as "configure" shouldn't read stdin, and this
8978 insulates us from problems (e.g., when testing for "cl").
8979 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8980 before invoking "hostname" or "uname".
8981 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8982 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8983 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8984 "</dev/null" since it's now done at the top of 'configure'.
8985 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8986 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8987 Also, replace grep with shell pattern-matching, to save a process.
8989 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8991 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8992 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8993 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8996 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8998 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8999 grep -q isn't portable. Improve grep -s explanation.
9000 Problem reported by Dan Manthey.
9002 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
9004 * doc/autoconf.texi (Special Shell Variables): Clarify
9005 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
9007 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9009 * doc/autoconf.texi: Use @acronym for DJGPP.
9010 Fix some @code's that should have been @env's, and vice versa.
9011 Sort environment variable names.
9012 Mention that shells no longer inherit IFS.
9013 Don't recommend PATH_SEPARATOR=';' so strongly.
9014 Mention that $RANDOM might expand to the empty string.
9015 "symlink" and "soft link" -> "symbolic link".
9016 Improve mktemp description (reported by Bruno Haible).
9018 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
9020 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
9021 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
9023 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
9026 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
9028 * NEWS: Mention AT_COPYRIGHT.
9030 * tests/local.at (AT_CMP): Use diff directly on input files rather
9033 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
9034 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
9036 2005-02-04 Noah Misch <noah@cs.caltech.edu>
9037 and Paul Eggert <eggert@cs.ucla.edu>
9039 * tests/autotest.at (Empty test suite): New test.
9040 * tests/torture.at (Substitute and define special characters)
9041 (Substitute a 2000-byte string, Define to a 2000-byte string)
9042 (Substitute a newline, Define a newline): New tests.
9044 2005-02-04 Noah Misch <noah@cs.caltech.edu>
9046 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
9047 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
9048 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
9049 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
9050 (Standard regular expressions): New test.
9051 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
9052 excess test name quoting.
9053 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
9054 CPPFLAGS to `configure' instead of setting it in `configure'.
9056 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
9057 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
9060 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
9061 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

9155 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9156 Update the long comment explaining it.
9158 m4_require no longer writes an ``is required by'' line to the
9159 execution stack. It contains only one bit of non-redundant
9160 information: that the macro was required, not called. And even
9161 this bit is useless in most situations: have you ever met a macro
9162 which both calls and requires the same macro?
9164 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9165 (_m4_defun_pro_outer): ... only via this macro, for the outermost

9172 (_m4_require_call): Use it.
9173 * tests/m4sugar.at (m4_require): Expect output without the
9174 ``is required by'' messages.

9212 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
9213 Warn about newline stripping in `` and $(). Update Solaris
9215 (Limitations of Builtins): Use expr "X...", not expr "x...", as
9216 X insulates us from future changes to Posix.
9217 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

9270 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
9271 stored in _m4_divert_diversion or _m4_divert_dump.
9272 (m4_divert_pop): When the parameter is given, compare the symbolic
9273 name with the last diversion pushed on the stack. Previously, the
9274 current diversion was compared with the numeric value of the
9275 diversion given as the parameter.
9276 (m4_require): If the macro hasn't been expanded yet, call ...
9277 (_m4_require_call): this new macro.

9531 * configure.ac (test suite): Cease to generate wrapper scripts.
9532 * configure: Regenerate.
9533 * lib/freeze.mk (MY_AUTOM4TE): Wrap the uninstalled autom4te directly.
9534 (m4f_dependencies): Adjust accordingly.
9535 * tests/Makefile.am (Wrappers): Generate wrapper scripts.
9536 (wrapper.in): Generate it in the build directory.
9537 (MAINTAINERCLEANFILES): Delete wrapper.in.
9538 (CLEANFILES): Add wrapper.in.
9539 * tests/wrapper.as: Move AS_INIT to very top, preserving copyright in
9540 the output. Replace each $as_me with a @wrap_program@.
9541 * tests/wrapper.in: Delete it; we always build it.
9543 * bin/Makefile.am (autoconf.in): Generate it in the build directory.
9544 (EXTRA_DIST): Remove autoconf.in.
9545 (CLEANFILES): Add autoconf.in.
9546 (autoconf): Find autoconf.in in the build directory.
9547 * bin/autoconf.in: Delete it; we always build it.
9549 2004-12-08 Noah Misch <noah@cs.caltech.edu>
9551 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
9552 PATH members so as to not prepend an empty element. Move a comment.
9553 * Makefile.am (SUBDIRS): Build in `tests' last.
9554 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
9556 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9558 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
9559 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
9560 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
9561 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
9563 2004-12-07 Stepan Kasal <kasal@ucw.cz>
9565 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

9576 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
9577 out the common code to ...
9578 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
9579 value of the #define--default to 1, iff the macro was called
9580 with exactly one parameter.
9582 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
9584 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9585 "char c = '\200';" rather than "char c = 0x80;" as the
9586 latter doesn't conform to the strict C standard due to
9587 overflow on signed char hosts.
9589 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
9590 to -qlanglvl=ansi. We don't want to disable extensions.
9592 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
9594 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
9595 (Using Autotest, testsuite Scripts, Writing testsuite.at):
9596 Reword slightly to avoid some English-language problems noted

9642 * doc/autoconf.texi (Autoconf Language): Explain that
9643 ``descriptions'' may not be double quotes.
9644 (Quotation Rule Of Thumb): Likewise.
9645 (Pretty Help Strings): Likewise; remove the wrong comment;
9646 simplify the examples and improve their quoting.
9648 2004-11-13 Stepan Kasal <kasal@ucw.cz>
9650 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
9651 the $1_found variable, don't test whether the file is executable;
9652 Both things are checked ...
9653 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces

9665 limitations. Reorder paragraphs for clarity.
9667 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
9669 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
9670 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
9671 variants", "Unix", and some related minor wording fixups.
9673 (Shellology, Special Shell Variables): Document that the Zsh
9674 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
9675 to Alexandre Duret-Lutz for this info.

9686 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
9688 * doc/autoconf.texi (auindex): New macro.
9689 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9690 Problem reported by Stepan Kasal.
9692 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
9694 Fix problems reported by Andreas Buening in:

9696 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9698 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9699 readable; it's not true in OS/2-emx.
9701 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9703 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9704 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9705 (trivial change). Problem and patch reported by Andrew Church in:
9706 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9708 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
9710 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

9729 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
9733 * README: Add advice about m4 1.4.2.
9735 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9736 texinfo.tex for now (done by hand now).
9737 * Makefile.maint (wget_files, cvs_files):
9738 Remove ansi2knr.c; nobody uses it.
9739 (ansi2knr.c-url_prefix): Remove.
9740 (cvs-update): Fix test for failure. I don't know why it ever
9743 * doc/autoconf.texi: Update URLs, some of which went stale.
9744 Use @uref rather than @href.
9746 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9747 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9749 * config/config.guess, config/config.sub, config/elisp-comp,
9750 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9751 doc/fdl.texi, doc/standards.texi: Sync with master copy.

9761 Use "file name" rather than "filename" or "path",
9762 to be consistent with the terminology of the GNU coding standards.
9764 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9766 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9767 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9768 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9769 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9771 More fixes to support spaces in the name of the build directory.
9772 This isn't a complete fix but it's an improvement.
9774 * bin/autoconf.as (autom4te_options): New var.
9775 Use it instead of appending to AUTOM4TE, so that we can allow
9776 spaces in the build directory's absolute name.
9777 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9778 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9779 AT_CHECK_NOESCAPE): Likewise.
9780 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9781 main program): Likewise.

9792 and isnan. From a suggestion by Kevin Ryde.
9794 * lib/Autom4te/General.pm (END): Return correct exit status even
9795 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9797 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9799 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9800 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9801 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9803 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9805 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9806 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9807 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9808 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9809 * lib/autom4te.in (Automake-preselections): Preselect
9810 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9812 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9814 * lib/autom4te.in (Automake-preselections): Preselect
9815 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

9827 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9828 with pdksh, too. Problem reported by Patrick Welche via
9830 * doc/autoconf.texi (Shellology): Note that set -o posix is
9831 useful for pkdsh, too.
9833 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9835 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9836 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9837 Don't fail if ENV or BASH_ENV is readonly.
9838 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9839 etc. are read only. Problem reported by Ludovic Courtes.
9841 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9843 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9844 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9847 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9849 * doc/autoconf.texi (File System Conventions): Warn about
9850 names like "aux". Problem reported by Eric Blake.
9852 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9853 by zero instead of array size, so that we can use any arithmetic
9854 constant expression (instead of requiring an integer constant
9855 expression). This allows us to test expressions like DBL_MAX <
9856 LDBL_MAX, which didn't conform to the C standard using the old
9858 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9859 now that we can do floating-point tests at compile time.
9861 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9863 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9864 and LDBL_EPSILON, as the resulting expression isn't an
9865 integer constant expression and violates the C standard.
9866 Problem reported by Nelson H. F. Beebe. Also, check
9867 for "L" suffix, and check that long double doesn't have
9868 worse range or precision than double, that mixed-mode
9869 arithmetic doesn't generate a diagnostic, that double
9870 constants fit in long double.
9872 2004-06-03 Kevin Ryde <user42@zip.com.au>
9874 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9875 malloc(0) and realloc(NULL,size).
9877 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9880 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9882 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9883 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9886 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9888 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9889 can be rewritten using if-then-else. Suggested by Bruno Haible.
9891 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9893 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9894 Problem reported by Stepan Kasal.
9896 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9898 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9899 change). Patch reported by Ralf Wildenhues in
9900 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9902 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9903 function F exists if the compiler and linker let you compile an
9904 expression like (F != 0). Recent versions of GCC optimize away
9905 the reference to F in that case, since every function address must
9906 be nonzero, so the link succeeds even if F does not exist.
9907 Problem reported by Manu in
9908 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9910 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9911 "Unix". Many uses changed.

9922 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9923 referencing AC_FUNC_STRERROR_R.
9925 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9926 note pessimistic assumption when cross compiling.
9928 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9930 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9931 (until 2004) invoked subcommands with sh -e, contra POSIX.
9932 Reported by Kevin Ryde.
9934 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9936 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9937 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9938 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9939 `test -f " /usr/bin/grep"', which _always_ failed.
9940 (AC_PROG_SED): Ditto bogus PATH fix.
9941 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9942 requires that grep correctly supports _multiple_ `-e' options, rather
9943 than stating only that grep should accept `-e'.
9945 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9947 Port to C99, which requires that 'exit' be declared.
9949 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9950 to ensure that stdlib.h is included.
9951 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9952 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9953 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9954 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9955 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9956 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9957 when using 'exit' in a test; C99 requires that 'exit' be declared.
9959 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9961 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9962 now prefers 'grep' implementations that accept -e.
9963 (Limitations of Usual Tools): Describe problems of traditional
9964 egrep and fgrep with long input lines, and of traditional grep
9966 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9967 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9968 All callers changed. Append /usr/xpg4/bin to the PATH, for
9970 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9971 the user with complaints about multiple -e options.
9972 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9973 Define it with AC_PROG_GREP.
9974 * configure.ac (AC_PROG_GREP): Add.
9975 * lib/freeze.mk (GREP): New macro.
9977 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9979 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9980 a possible candidate only after all others fail, rather than
9981 consulting it first. This improves backward compatibility by
9982 better reflecting the way shell selection occurred in previous
9983 versions of Autoconf, and should help to avoid triggering latent
9984 problems in other packages, such as the one in Automake where zsh
9985 is not handled robustly:
9986 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9987 Although it is not Autoconf's responsibility to work around
9988 problems in Automake, it nevertheless makes sense to avoid
9989 introducing unnecessary incompatibilites.

10013 2004-04-20 Paul Eggert <eggert@twinsun.com>
10015 * tests/c.at (C keywords): Don't assume that GCC supports
10016 "restrict" and "inline", as sufficiently-old GCC versions do not
10017 (also, GCC configured to be in pedantic C89 mode does not).
10018 Problem reported by Sumit Pandya in:
10019 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
10021 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
10022 consider -g to work if it generates warnings when plain compiles

10037 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
10038 best tool so far counter rely on the tool path variable name to

10040 the length check on a previous tool.
10042 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
10043 match expression argument, as different greps have different

10075 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
10076 now defines HAVE_DECL_TZNAME if it is declared, when
10077 HAVE_STRUCT_TM_TM_ZONE is not defined.
10078 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.

10148 * bin/Makefile.am (edit): Don't use $< in a context where
10149 POSIX doesn't require support for it. Use $@.in instead.
10150 Problem reported by Anthony N. Frasso in
10151 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

10160 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10162 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
10163 is not always thread-safe. Report from Nathanael Nerode.

10167 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10168 problem on QNX reported by Stephen Rasku in
10169 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
10171 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10172 $(m4sh_m4f_dependencies); this removes a FIXME.
10173 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10174 (MAINTAINERCLEANFILES): Split into pieces,
10175 one per related section. Add $(srcdir)/wrapper.in.
10177 2004-02-09 Paul Eggert <eggert@twinsun.com>
10179 * doc/autoconf.texi (Setting Output Variables): Emphasize that
10180 AC_SUBST provides no portable way to escape literal newlines.
10182 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10183 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10184 Darwin uses -lcrt2.o and there's little point to cataloging all
10185 the system variants. Partial fix reported by Andreas Waechter in:
10186 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

10202 the behavior of the third argument.
10203 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
10204 correctly the behavior of the third argument. Document
10205 what the three macros that AU_DEFUN defines do. Fix

10211 Paul Eggert <eggert@twinsun.com>
10213 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
10214 (AS_INIT): Output shell initialization there. Removed optional
10215 parameter. Expand _AS_SHELL_FN_SPY.
10216 (AS_INIT_WITH_SHELL_FN): Removed.
10217 (_AS_SHELL_FN_SPY): New macro.

10224 (_AS_RUN): Move it here, support testing with eval.
10225 (AS_REQUIRE_SHELL_FN): Require shell functions when
10227 (_AS_LINENO_WORKS): Put around braces, we do not
10228 trigger the bash bug anymore.
10229 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10230 use AS_INIT_WITH_SHELL_FN.
10231 * bin/autoconf.in, tests/wrapper.in: Regenerated.
10233 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

10239 (AU_DEFUN): Honor the third parameter, create autoupdate
10240 macros with AU_DEFINE.
10241 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
10242 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

10261 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
10262 2003 (except 1997) to the list of copyright years. This undoes
10263 the 2003-05-22 change, which removed the older years from the list.
10264 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

10272 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
10274 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
10275 egrep and fgrep respectively if $GREP -E/-F don't work.
10276 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10277 _AC_PROG_GREP, and AC_PROG_SED.
10278 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10279 longest input length accepted by a command.

10308 2004-01-26 Paul Eggert <eggert@twinsun.com>
10310 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10311 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10312 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10313 not <inttypes.h>. Problem reported by Tim Mooney in
10314 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10315 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10318 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10319 otherwise "make check" fails because it forbids cmp (I guess
10320 because cmp treats files as binary on DOS-like systems).
10322 * tests/mktests.sh: Update copyright date to 2004, since some tests
10323 have changed in 2004.
10325 2004-01-23 Gary V. Vaughan <gary@gnu.org>
10327 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
10328 non-truncating sed or gsed program in PATH.
10329 * tests/acprograms.at: Add it.
10330 * doc/autoconf.texi (Particular Programs): Document it.
10333 2004-01-15 Paul Eggert <eggert@twinsun.com>
10335 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10336 -std1 disables some useful extensions on Tru64. Problem reported
10337 by N. Lichtmaier in
10338 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10340 2004-01-14 Paul Eggert <eggert@twinsun.com>
10342 * doc/autoconf.texi (Programming in M4sh): Document that
10343 AS_MKDIR_P succeeds if the destination is a symbolic link
10344 to an existing directory.
10345 (Limitations of Usual Tools): Note that mkdir -p might not
10346 succeed on symlinks to directories.
10348 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10350 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10351 * bin/autoheader.in: Grammar fix in message.
10352 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10353 Test for dir before calling mkdir -p. (trivial changes)
10355 2004-01-13 Eric Blake <ebb9@byu.net>
10357 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10358 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10360 2004-01-10 Jim Meyering <jim@meyering.net>
10362 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10364 2004-01-09 Paul Eggert <eggert@twinsun.com>
10366 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10367 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10368 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10369 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10370 AC_COMPILE_IFELSE, since we now assume our caller invokes
10371 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10372 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10373 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10374 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10376 2004-01-07 Paul Eggert <eggert@twinsun.com>
10378 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10379 `"'...'"`, as it's confusing (and I suspect it may not work on
10380 some platforms). The code was incorrect anyway, as it assumed
10381 that \$ evaluated to itself in that context. Reported by
10382 Alexandre Duret-Lutz.
10384 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10386 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10387 and _LT_AC_TAGCONFIG.
10389 2004-01-06 Paul Eggert <eggert@twinsun.com>
10391 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10392 example, and add more examples. Reported by Eric Sunshine.

10409 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
10410 by doing lineno substitution only on lines containing "$LINENO".
10412 2004-01-04 Paul Eggert <eggert@twinsun.com>
10414 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10415 Use "rm -f" to remove conftest.sed, not plain "rm".
10416 Bug reported by David Relson in
10417 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10419 * Makefile.am (autom4te-update):
10420 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

10559 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10560 than $target since the latter is not usual, add guidelines on when to

10742 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10743 -mGLOB_options_string stuff for Intel ifc, which can cause

10768 cache variable instead of $G77 to decide whether to include -O2,
10769 since $G77 is specific to Fortran 77.

10779 arguments so that it can be used with syntax identical to
10780 AC_PROG_F77, and so that we can more easily decide to
10781 remove/deprecate the DIALECT optional argument in the future if it
10782 proves troublesome.
10783 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10784 non-freeform-supporting compilers. Document freeform flags.
10786 2003-10-03 Akim Demaille <akim@epita.fr>

10848 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10849 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative

10853 2003-09-26 Akim Demaille <akim@epita.fr>
10855 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10856 directory for AC_CONFIG_COMMANDS' first argument exists.
10857 This makes valid the invocation of _AC_SRCPATH that follows.
10858 Reported by Eric Sunshine.
10859 * doc/autoconf.texi (Configuration Commands): Adjust.
10861 2003-09-26 Akim Demaille <akim@epita.fr>

10882 The test suite are sometimes assigning timings incorrectly.
10883 Reported by Henk Krus.
10884 Diagnosed by Nicolas Joly.
10886 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10888 Instead of making AT_help a sequence of assignments to grow
10889 $at_help_all, just make AT_help_all be the growing contents of
10890 $at_help_all, and make a single assignment in...
10892 (at_times_skip): Flip the meaning and rename as...
10893 (at_times_p): this.
10894 (AT_INIT): When summarizing the test that ran, remove

10904 (ifnames): chmod -w.
10905 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10906 executables, not bin/ executables! Otherwise all the magic needed
10907 to find non installed files is turned off. This caused a failure
10908 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10909 as found in its environment (sent by tests/autoreconf): pointing
10910 to bin/autom4te that could not find its files.

11141 2003-08-21 Akim Demaille <akim@epita.fr>
11143 First stab at preserving warnings between calls to autom4te,
11144 including when the cache is used.
11146 There are still several issues: (i) there are too many runs of m4
11147 (one for include, one for warnings, and some more), (ii) warnings
11148 spreading on several lines are not handled gracefully, (iii) the
11149 code meant to have the call stack display for errors does not work
11150 (its handling should move from m4 to autom4te).
11152 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11154 (@preselect): Add m4_warn.
11155 ($exit_status): Remove, use $exit_code.
11156 ($help): Use Autom4te::ChannelDefs::usage.
11157 (&handle_m4): No longer define the m4_warnings.
11158 At each run, extract and report the warnings.
11159 Always cache the result, including if the exit status is on
11160 failure, since if nothing changes, we should result in the same
11161 failure, hence we can use the cache.
11162 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11163 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11165 (m4_warn): Redefine as a do-nothing: it is its invocation that
11166 matters, as warnings are now reported via traces.
11167 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11168 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11169 the latter reveals calls to the former.
11173 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
11175 2003-08-21 Akim Demaille <akim@epita.fr>

11195 (&catfile): Remove.
11196 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
11197 * bin/autoscan.in: Adjust.
11199 2003-08-20 Akim Demaille <akim@epita.fr>
11201 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
11202 Reported by Alexandre Duret-Lutz.
11204 2003-08-20 Akim Demaille <akim@epita.fr>
11206 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11207 * bin/autom4te: Adjust.
11208 In particular, be Autoconf tools are really silent when properly
11209 working, bind the verbosity of the 'note' channel to $verbose.
11210 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11211 (&xsystem, &contents): Remove, since they are exported by...
11212 * lib/Autom4te/FileUtils.pm: this.

11215 * lib/Autom4te/FileUtils.pm: here.

11334 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11335 not all of them. This fixes 1. the fact that when testing
11336 Autoconf there are many many config.log, 2. the incorrect use of
11337 top_srcdir to find config.log.
11338 Don't mix the detailed output of failed test with the summary of
11339 failures. Rather, append detailed log afterwards.
11341 2003-06-23 Akim Demaille <akim@epita.fr>

11401 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11402 (AT_INIT): Support for expected failures.
11404 2003-06-02 Akim Demaille <akim@epita.fr>

11413 2003-05-28 Paul Eggert <eggert@twinsun.com>
11415 * NEWS, doc/autoconf.texi (Particular Functions),
11416 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11417 is the inverse of localtime.
11419 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
11421 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11422 (handle_exec_errors): New function. Work around $! being
11423 altered by WEXITSTATUS.
11424 (xqx, xsystem): Use handle_exec_errors.
11426 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11428 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11429 Do not call `_exit()', simply modify `$?'.
11430 (xsystem): Reset $! before running system, and check it afterward.
11431 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11432 63 for version mismatches.
11434 2003-05-23 Akim Demaille <akim@epita.fr>
11436 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11437 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11438 the middle of a line).
11439 * lib/m4sugar/m4sugar.m4: Likewise.
11440 Remove useless spaces in comments.
11442 2003-05-23 Akim Demaille <akim@epita.fr>
11444 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11445 exit 63, so that we (or Automake's "missing") can tell the
11446 difference with a plain failure.
11447 * doc/autoconf.texi (Notices): Adjust.

11456 Paul Eggert <eggert@twinsun.com>
11458 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11459 Remove `#include <stdlib.h>' from the list; we should never
11460 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11461 resulting namespace pollution would cause other tests to fail.
11462 Configure scripts run with some older versions of g++ and HP's
11463 aCC would fail due to such an #include. Problems reported by
11464 Matthew Mueller in <http://bugs.debian.org/120704> and by
11466 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11467 In the test, use the test declaration before including <stdlib.h>,
11468 as that's closer to how it'll be used.
11470 2003-05-23 Akim Demaille <akim@epita.fr>
11472 * doc/autoconf.texi (Header Portability): ucred.h.
11475 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11477 Overhaul Autotest's logging: generate separate log files
11478 in testsuite.dir/NNN/testsuite.log, and append them to
11479 testsuite.log instead of re-running the test verbosely.
11481 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11482 file descriptor, write 0 to at_status_file instead of setting
11483 at_status=0, initialize some new variables (at_status_file,
11484 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11485 to rerun the tests, instead append the at_group_log to the
11486 at_suite_log when a test fails.
11487 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11488 with the AS_MESSAGE_LOG_FD redirected to stdout.
11489 (AT_CLEANUP): save the output status in $at_status_file
11490 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11491 its original place.
11492 (AT_CHECK): since tests are run with a redirected stdout,
11493 and used to be re-run in verbose mode, turn some $at_verbose
11494 into echo, and don't redirect the output of testing stdout
11497 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11498 the name of the debugging directory and information about
11501 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

11618 2003-05-06 Akim Demaille <akim@epita.fr>
11620 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11621 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11622 by aclocal.m4 is changed it might require the importing of another
11623 m4 extension file, i.e., aclocal must be run.
11625 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11626 (&parse_args): Use --force with aclocal if required and supported.

11640 2003-04-29 Derek Price <derek@ximbiot.com>
11642 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11643 seperator with m4_append_uniq(). It doesn't work.
11644 (AT_CLEANUP): Add `;' to end of at_help_all.
11645 (AT_INIT): Allow --keywords to be specified more than once. When
11646 grepping $at_help_all for keywords, use the field and keyword

11648 to support the new --keywords behavior.
11650 2003-04-27 Karl Berry <karl@freefriends.org>
11652 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11653 align better with others. I also made some of the individual
11654 entries on one line, for brevity and to make it easier for me to

11878 (and earlier versions) have a <limits.h> that declares
11879 gettimeofday and many other functions.
11881 2002-12-03 Paul Eggert <eggert@twinsun.com>
11885 * NEWS, configure.ac: Update version.
11887 * doc/fdl.texi: Upgrade to FDL version 1.2.
11889 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11890 nontrivially in main's body, so that f's external declaration is
11891 not optimized away in AIX. This should fix the bug reported by
11893 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11895 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11896 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11897 defined, to support freestanding compilers. This should fix the
11898 bug reported by Momchil Velkov in
11899 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11901 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

11933 Update from masters.
11935 2002-11-14 Akim Demaille <akim@epita.fr>
11937 * Makefile.maint: Sync with Bison, i.e.:
11938 (po-check): Scan .l and .y files instead of the
11939 .c and the .h files that they generate. This fixes the bug
11940 reported by Tim Van Holder in:
11941 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11942 Look for N_ as well as for _. Try to avoid matching #define for

11958 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11959 than assigning in main, to avoid HP cc +O3 optimizing it away.

11963 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11964 option. Process --recheck after parsing all options. Pass -q
11965 option to configure on --recheck.

11970 config.status -q option.
11972 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11974 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11975 Makefile.in if Makefile.am exists.
11976 (output): Strip `.am' from Makefiles. Don't

11997 Reported by Ezra Peisach.
11999 2002-11-05 Akim Demaille <akim@epita.fr>
12001 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
12003 We _have_ to stop using the old compatibility scheme that tried to
12004 avoid useless backslashes because Libtool 1.4.3 contains a
12005 AC_DEFINE([error_t], [int],
12006 [Define to a type to use for \`error_t' if it is not
12007 otherwise available.])
12008 We _have_ to quote the single quote and backslashes with \. The
12009 old compatibility scheme saw that ` was backslashed, and therefore
12010 did not quote the single quote. Hence before this patch, Autoconf
12011 was not compatible with Libtool.
12013 2002-11-04 Paul Eggert <eggert@twinsun.com>
12015 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

12056 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
12057 Make variable, not a shell variable.
12058 Suggested by Bruno Haible.
12060 2002-10-31 Akim Demaille <akim@epita.fr>

12381 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
12382 * lib/freeze.mk (check-forbidden-patterns): New.
12383 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
12384 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
12385 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
12387 Reported months ago by H. Merijn Brand.
12389 2002-10-17 Akim Demaille <akim@epita.fr>
12391 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
12393 2002-10-16 Paul Eggert <eggert@twinsun.com>
12395 * Makefile.maint (wget_files): Remove ansi2knr.c.
12396 (ansi2knr.c-url_prefix): Remove.
12398 2002-10-16 Akim Demaille <akim@epita.fr>
12400 Because of caching, some files that no longer exist and are no
12401 longer required can still cause errors.
12402 Reported by Alexandre Duret-Lutz.
12404 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
12405 to frozen files in @ARGV, as @ARGV must remain being a list of
12406 files. Rather, at M4 call sites, use this...
12407 (&files_to_options): New function.
12408 (&freeze): Use &error.
12409 (&up_to_date): If a file that was included according to the cache
12410 is no longer there, then the output is out dated.
12411 (&main): Don't even check whether a file is up to date is anyway
12413 * tests/tools.at (autom4te cache): New.
12415 2002-10-16 Akim Demaille <akim@epita.fr>
12417 * bin/autoconf.as: Kill dead options.
12418 * bin/autoupdate.in (&parse_args): Kill old options.
12419 * bin/autoreconf.in (&parse_args): Remove dead options.
12421 (&autoreconf): Report the directories we enter *and leave*, so
12422 that error messages can be easily located, and use GNU Make
12423 format, so that Emacs' compile mode understands us.
12424 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12425 if some file was changed instead of `print'.
12426 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
12427 (&parse_args): Remove the dead options.
12428 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
12429 autoheader's quiet mode.
12430 (AT_CHECK_AUTOUPDATE): Likewise.
12431 * tests/tools.at (autoupdate): Adjust.
12432 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12434 2002-10-11 Akim Demaille <akim@epita.fr>
12436 No longer use CPP to check for the existing of headers: use CC to
12437 check for compilability.
12439 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
12440 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
12441 (_AC_CHECK_HEADER_NEW): Rename as...
12442 (AC_CHECK_HEADER): this.
12444 * lib/autotest/general.m4 (AT_INIT): Include the failed test
12445 numbers in the Subject suggestion.
12447 2002-10-11 Akim Demaille <akim@epita.fr>
12449 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
12450 Suggest using AC_CHECK_DECLS instead.
12452 2002-10-11 Akim Demaille <akim@epita.fr>
12454 * tests/torture.at (AC_ARG_VAR): Have configure report the value
12457 2002-10-11 Akim Demaille <akim@epita.fr>
12459 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
12460 file name to enable parallel executions.
12461 From Sam Varshavchik.
12463 2002-10-08 Akim Demaille <akim@epita.fr>
12465 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12466 aclocal invocation, as Gettext macros might not be visible to
12468 Instead of blindly running autopoint, scan configure.ac (not the
12469 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12470 Reported by Paul D. Smith.
12472 2002-10-08 Paul Eggert <eggert@twinsun.com>
12474 Work around problems found when POSIXLY_CORRECT=1 is set.
12475 None of this seems to have anything to do with POSIX, really,
12476 but it's how Perl getopt works.
12477 * bin/autom4te.in (parse_args): Configure GetOpt with
12479 * doc/autoconf.texi (Invoking autom4te):
12480 --warning -> --warnings.
12481 * lib/autom4te.in: --warning -> --warnings.
12483 2002-09-28 Akim Demaille <akim@epita.fr>
12485 * doc/autoconf.texi (autom4te.cache): New section.
12487 2002-09-28 Akim Demaille <akim@epita.fr>
12489 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
12490 (Automake-preselections): Update.
12491 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
12493 2002-09-28 Akim Demaille <akim@epita.fr>
12495 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
12496 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
12497 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12498 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12500 2002-09-28 Akim Demaille <akim@epita.fr>
12502 * tests/torture.at (Configuring subdirectories): Be robust to
12503 users who use config.site to require for a cache: in this case,
12504 the two last configure runs, using two different sets of
12505 arguments, trigger a legitimate error.
12507 2002-09-28 Akim Demaille <akim@epita.fr>
12509 * tests/m4sh.at (Functions Support, Functions and return Support):
12512 2002-09-28 Akim Demaille <akim@epita.fr>
12514 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12515 autoheader are Perl programs.
12516 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12517 (autom4te): Specify that the sources are in the $srcdir.
12518 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12520 2002-09-28 Akim Demaille <akim@epita.fr>

12523 (tm_zone): Move their rules to...
12524 * lib/autoconf/types.m4: here, using AN_ macros.
12525 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12526 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12527 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
12528 * lib/autoconf/programs.m4: here.

12537 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12538 that were listed in the original autoscan.list.
12539 * lib/autoconf/headers.m4: Similarly with headers.
12540 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12541 (.m4.m4f): Don't pass --prepend-include, since that's done by
12542 tests/autom4te itself.
12543 * lib/autoscan/Makefile.am: Include freeze.mk.
12544 (autoscan.list): New target --this file is no longer a source.
12545 (autoscan.pre): New file.
12547 2002-09-28 Akim Demaille <akim@epita.fr>
12549 * bin/autoscan.in (@kinds): Make them singular.
12551 (&init_tables): When --debug, report the list of rules to ease
12552 tracking changes in autoscan.list.
12553 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12555 2002-09-28 Akim Demaille <akim@epita.fr>
12557 * lib/autoscan/functions, lib/autoscan/headers,
12558 * lib/autoscan/identifiers, lib/autoscan/makevars,
12559 * lib/autoscan/programs: Merge into...
12560 * lib/autoscan/autoscan.list: this.
12561 * bin/autoscan.in (&init_tables): Adjust.
12563 2002-09-28 Akim Demaille <akim@epita.fr>
12565 * lib/autoscan/functions, lib/autoscan/headers,
12566 * lib/autoscan/identifiers, lib/autoscan/makevars,
12567 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12568 `functions' line is now prefixed with `function:'.
12569 * bin/autoscan.in (&init_tables): Adjust.
12571 2002-09-28 Akim Demaille <akim@epita.fr>
12573 From now on, autoscan files must always map a macro name to a
12574 word: there is no `default' macro for autoscan.
12576 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12578 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12581 2002-09-28 Akim Demaille <akim@epita.fr>
12583 * bin/autoscan.in (%c_keywords): Remove.
12584 (&used): Keep only track of the words we might be interested in.
12585 (&output_kind): It is no longer needed to look for non active
12588 2002-09-27 Akim Demaille <akim@epita.fr>
12590 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12591 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12592 * lib/autoscan/functions: Adjust.
12593 * doc/autoconf.texi (Particular Functions): Adjust.
12595 2002-09-27 Akim Demaille <akim@epita.fr>

12599 Thanks to Bill Moseley and Paul Eggert.
12600 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12601 the tmpdir must be created.
12602 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12603 dir be in the build tree, instead of $TMPDIR.
12605 2002-09-27 Akim Demaille <akim@epita.fr>
12607 * bin/autoscan.in: Improve the comments.
12608 (&parse_args): Drop obsolete undocumented options.
12609 (&output_kind): Output warnings.
12610 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

12615 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12616 Reported by Ralf Corsepius.
12617 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12619 2002-09-26 Akim Demaille <akim@epita.fr>
12621 Single suffix rules and seperated dependencies are not portable.
12623 * doc/autoconf.texi (Installation Directory Variables): Update.
12624 (Limitations of Make): Some about `Single Suffix Rules and
12625 Separated Dependencies'.
12626 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12627 (ifnames, autoscan, autom4te): Un-factor into several rules.
12629 2002-09-25 Paul Eggert <eggert@twinsun.com>
12631 * BUGS (Interoperability bugs): New section. Mention libtool
12632 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12634 2002-09-24 Paul Eggert <eggert@twinsun.com>
12636 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12637 make handles suffix-rules differently from GNU make.
12639 * bin/Makefile.am (SUFFIXES, .in): Remove.
12640 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12641 Move the body of the old .in rule here.
12643 2002-09-16 Akim Demaille <akim@epita.fr>
12645 i960 compilers create `b.out' files by default.
12646 Reported by Ralf Corsepius.
12648 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12649 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12651 2002-09-13 Paul Eggert <eggert@twinsun.com>
12653 * doc/autoconf.texi (Particular Headers): Remove obsolete
12654 reference to `struct timezone' in the description of
12657 2002-09-13 Akim Demaille <akim@epita.fr>
12661 * config/config.sub, config/config.guess: Update.
12662 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12663 * Makefile.am: Adjust.
12665 2002-09-13 Akim Demaille <akim@epita.fr>
12667 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12668 reading config.log when the compiler is rejected.
12669 Suggested by Guido Draheim.
12671 2002-09-13 Akim Demaille <akim@epita.fr>
12673 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12674 (chdir_init) might hang when stat'ing mounted directories.
12675 Reported by Vance Shipley.
12677 2002-09-12 Akim Demaille <akim@epita.fr>
12679 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12682 2002-09-12 Akim Demaille <akim@epita.fr>
12684 * doc/autoconf.texi (Defining Symbols): Present two different
12685 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12686 difference between 1 argument calls, and 2-3 argument calls.
12688 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12690 * doc/autoconf.texi: Review grammar and punctuation.
12692 2002-09-11 Paul Eggert <eggert@twinsun.com>
12694 * doc/autoconf.texi: Fix minor formatting, spelling, and
12696 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12697 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12700 2002-09-11 Akim Demaille <akim@epita.fr>
12702 * doc/autoconf.texi (Questions): Rename as...
12704 (Defining Directories): New.
12706 2002-09-09 Akim Demaille <akim@epita.fr>
12708 * doc/autoconf.texi (Making testsuite Scripts): Update.
12709 Suggested by Nishio Futoshi.
12711 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12713 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12714 plain `@' is wanted.
12716 2002-09-09 Akim Demaille <akim@epita.fr>
12718 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12719 `duplicates', since the algorithm was too naive and could keep
12720 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12721 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12722 Reported by Ralf Corsepius.
12723 * tests/torture.at (Configuring subdirectories): Exercise these
12726 2002-09-09 Akim Demaille <akim@epita.fr>
12728 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12729 looking for a replacement file.
12730 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12731 directory is relative.
12732 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12733 directory definition.
12734 Reported by Andreas Schwab and Jim Meyering.
12736 2002-09-06 Akim Demaille <akim@epita.fr>
12738 * doc/autoconf.texi (Setting Output Variables): Clarify what
12739 precious variables are.
12740 Suggested by Pontus Skoeld.
12742 2002-09-05 Akim Demaille <akim@epita.fr>
12744 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12745 (ifnames, autoscan, autom4te): Since we don't only depend on
12746 configure.ac variables (such as VERSION etc.), but also on prefix
12747 and so forth, depend on Makefile, not configure.ac.
12748 Reported by Alexandre Duret-Lutz.
12749 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12751 2002-09-05 Kevin Ryde <user42@zip.com.au>
12753 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12754 doesn't seem to be confined to ia64, just say "some versions".
12756 2002-09-04 Akim Demaille <akim@epita.fr>
12758 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12760 * Makefile.am (maintainer-clean-local): Remove.
12761 (MAINTAINERCLEANFILES): Remove COPYING.
12763 2002-09-03 Paul Eggert <eggert@twinsun.com>
12765 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12766 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12769 2002-09-03 Akim Demaille <akim@epita.fr>
12771 * configure.ac: Bump to 2.53d.
12772 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12773 as of today, on Automake's team suggestion.
12775 2002-09-03 Akim Demaille <akim@epita.fr>
12779 2002-09-02 Akim Demaille <akim@epita.fr>
12781 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12783 * configure.ac: Disable SITE_MACRO_DIR.
12785 2002-09-02 Jim Meyering <meyering@lucent.com>
12787 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12788 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12789 Also, tweak grammar: s/make sure to/be sure to/.
12791 2002-09-02 Paul Eggert <eggert@twinsun.com>
12793 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12794 directory names are generally preferable to physical names.
12796 2002-09-02 Akim Demaille <akim@epita.fr>
12798 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12799 Reported by Raja R. Harinath.
12800 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12801 * bin/autoupdate.in: Use error instead of die.
12803 2002-09-01 Paul Eggert <eggert@twinsun.com>
12805 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12806 ordinary shell concatenation rather than echo+tr+sed command that
12807 runs afoul of a long-line-related sed bug in Solaris 8.
12809 * bin/autoheader.in (parse_args): --warning -> --warnings.
12811 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12812 stdout, as traditional "ls" does.
12813 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12814 _AC_COMPILER_EXEEXT_O): Likewise.
12815 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12817 * bin/autoconf.as: Add --prepend-include option. This patch was
12818 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12819 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12821 * bin/autoconf.in, configure: Regenerate.
12823 * doc/autoconf.texi (Special Shell Variables): Mention
12824 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12826 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12827 MAILPATH and set PS1, PS2, PS4 to default values, to work
12828 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12829 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12830 the Autoconf documentation specifies; fall back to "unset" only if
12831 this fails. Use a shell for-loop for this rather than an m4 loop,
12832 to shorten the output script.
12834 2002-08-30 Paul Eggert <eggert@twinsun.com>
12836 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12837 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12838 for the CDPATH problem. Document PWD.
12839 (Limitations of Builtins): Document the problem that "cd $foo" and
12840 "ls $foo" may refer to different directories in shells conforming
12841 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12842 example, since the old example is now out of date.
12844 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12845 FOO" and "ls FOO" talk about different directories; this catches
12846 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12849 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12850 of rolling our own unset.
12851 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12852 in practice we needn't worry about CDPATH if unset doesn't work.
12854 * Makefile.in, aclocal.m4, bin/Makefile.in,
12855 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12856 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12857 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12858 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12859 tests/Makefile.in: Regenerate with Automake 1.6.3.

12878 * lib/Autom4te/General.pm (&xqx): New.
12879 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12880 hand, which is not portable.

12883 Use &error instead of die.

12889 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the

12895 * doc/autoconf.texi (Invoking autom4te): End the option table,

12917 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12918 * Makefile.am (INSTALL): Use the new macros.

13063 2002-06-27 Paul Eggert <eggert@twinsun.com>

13207 This improves on an earlier suggestion by H. Peter Anvin.
13209 2002-05-16 Paul Eggert <eggert@twinsun.com>
13211 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13212 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13213 Both macros now accept an optional source-dir arg.
13214 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13216 * NEWS: Document this.
13217 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13219 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13220 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13221 not for GNU extensions; this undoes part of the 2000-11-03 change,
13222 reverting to 2.13-compatible behavior.
13223 Add new optional argument DIR.
13224 (AC_FUNC_FNMATCH_GNU): New macro.
13226 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.

13230 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13231 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13232 and it causes a 'test' syntax error if it fails.
13233 Bug reported by Stephen Gildea.
13235 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13236 If prototypes are supported, use them to check this at compile-time,
13237 instead of trying to check it at run-time. If we must do a run-time
13238 check, assume that setvbuf is standard when cross-compiling, as
13239 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13240 Bug reported by Paul D. Smith.
13242 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13243 argument specifying location of getloadavg.c. This removes a
13244 FIXME. This idea was taken from Jim Meyering's implementation in
13246 * doc/autoconf.texi (Particular Functions): Document this.
13247 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13248 that's what the code does; this fixes a bug reported by

13253 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13254 autopoint instead of gettextize.
13255 ($uses_alocal): Rename as...
13256 ($uses_aclocal): this.
13257 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13258 Suggested by Bruno Haible.
13260 2002-05-03 Akim Demaille <akim@epita.fr>
13262 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13264 2002-04-29 Paul Eggert <eggert@twinsun.com>
13266 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13267 files to be 1 second older; just set them to be the same time.
13268 Also, sleep 1 second after the first aclocal, to work around
13269 problems with sub-second time stamps on the input files.
13271 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13273 * doc/autoconf.texi: Mention "set -e -x" lossage
13274 under node "Limitations of Builtins".
13276 2002-04-29 Akim Demaille <akim@epita.fr>
13278 * doc/install.texi: Better wording for setting variables when
13280 From Christian Cornelssen.
13282 2002-04-29 Akim Demaille <akim@epita.fr>
13284 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13285 of lack of $LINENO support, then the test will compare the $LINENO
13286 in testsuite vs. the lineno in the test file. This is wrong, of
13288 Be sure to protect it.
13289 Reported by Patrick Welche.
13291 2002-04-25 Akim Demaille <akim@epita.fr>
13293 * doc/autoconf.texi (Obsolete Macros): Typo.
13294 Reported by Vladimir Volovich.
13296 2002-04-25 Akim Demaille <akim@epita.fr>
13298 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13299 than some of the input files, hence, on the second run of aclocal,
13300 if some of its input are younger, make them older.
13301 Suggested by Paul Eggert.
13303 2002-04-25 Akim Demaille <akim@epita.fr>
13305 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

13312 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13314 (_AC_INIT_PREPARE): Use them to log them.
13315 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13316 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13317 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13318 _AC_SUBST_FILES and _AC_SUBST_VARS.
13319 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13321 2002-04-24 Akim Demaille <akim@epita.fr>
13323 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13324 autoheader, so that automake does not complain about a missing
13325 config.h.in that was to be created.
13327 2002-04-23 Akim Demaille <akim@epita.fr>
13329 * bin/autoheader.in (parse_args): --warning takes an argument.

13379 Minor spelling and grammar fixes.
13381 * doc/autoconf.texi: Follow the outline suggested in the GNU
13382 Sample Texts sections of the Texinfo 4.2 manual. Most
13383 importantly, this makes sure that the copyright notices appear in
13384 all output formats. You probably need Texinfo 4.2 to generate

13425 From Oliver Kiddle and Peter Stephenson.
13427 Have M4sh perform minimal shell sanitizing.
13429 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13431 (_AS_PREPARE): this new macro.

13436 Adjust Autoconf and Autotest.

13485 Use dnl, not the KILL diversion.
13487 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13488 (AC_CONFIG_LINKS): here.
13490 Don't use the KILL diversion, as it kills spurious output, which
13491 results in failures being hidden.
13492 Use m4_defn where appropriate.
13493 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13494 after the second argument.
13496 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13497 syntax, as it is provided by M4sugar.

13540 to avoid versions of HP C which don't allow that.

13558 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13559 as POSIX requires, as it doesn't work with Zsh.
13560 * doc/autoconf.texi (Assignments): Document the problem.
13562 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

13570 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13571 problem with here-document buffer boundaries.
13573 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13574 when reinvoking the shell, to work around problems with installers
13575 who put strange things like "cd" commands in their environments.

13600 (Limitations of Usual Tools): Add mkdir section.
13602 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13603 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13604 back on AS_DIRNAME to compute prefixes otherwise; this is
13605 roughly what mkinstalldirs does. That way, we need not have
13606 our own filename disassembler. The old disassembler did not
13607 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13609 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13610 Create at_test_all by a series of assignments,
13611 not by a single assignment of a long string. The latter causes ksh
13612 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13613 presumably because of a buffer overrun.
13615 2002-03-14 Paul Eggert <eggert@twinsun.com>
13617 * lib/autotest/general.m4 (at_times_skip):
13618 Renamed from at_times. Now a boolean.
13619 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13620 says 'times: not found'.

13665 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13667 2002-03-08 Akim Demaille <akim@epita.fr>
13669 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13670 aliases the actual variables, and modifications of the former
13673 2002-03-08 Akim Demaille <akim@epita.fr>
13675 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13676 because of C-c: have m4 output in tmp files, then mv them.

13710 * doc/autoconf.texi (Transforming Names): Equality between target
13711 and host is irrelevant.
13712 (Specifying Names, Canonicalizing): Remove all references to the
13713 backward compatibility hooks. Rather, collect them all into...
13714 (Hosts and Cross-Compilation): this new section.
13715 * doc/install.texi (System Type): Ditto.
13716 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13717 that `--host' implies cross-compilation.

13725 that it contains exactly the items, not an expression which
13726 evaluation is the current item.
13727 (m4_re_string, m4_re_word): Don't over quote them.
13729 2002-03-04 Akim Demaille <akim@epita.fr>
13731 Instead of having stacking `shift's evaluated at the end, let
13732 `foreach' loops immediately evaluate them.
13734 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13735 $*. This is the n-th time I change my mind, but hopefully this is
13738 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13740 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13741 it was only a hack for m4_text_wrap.
13742 (m4_car2): Remove, replaced by...
13744 (_m4_foreach): Adjust.
13745 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13746 m4_bpatsubst for clarification.

13862 optional are the sum of the previous files on the command line'.
13863 Also, pass `--reload-state=' on them, so...
13864 (handle_m4): don't.
13865 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13866 (M4sh): Rely on M4sugar.
13867 (Autotest, M4sh, M4sugar): Use frozen files.
13869 2002-01-31 Akim Demaille <akim@epita.fr>
13871 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13872 * doc/autoconf.texi (Initializing configure): Adjust.
13874 2002-01-30 Akim Demaille <akim@epita.fr>
13876 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13877 alphanumeric to `-' instead of `_'.
13879 2002-01-30 Akim Demaille <akim@epita.fr>
13881 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13882 for plain code, the other for cross-compilation code. The latter
13883 is now run with GCC only.
13884 * doc/autoconf.texi (Compilers and Preprocessors): New.
13886 2002-01-30 Akim Demaille <akim@epita.fr>
13888 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

13891 change AC_INIT default values.
13893 2002-01-29 Akim Demaille <akim@epita.fr>
13895 * tests/torture.at (Configuring subdirectories): Use configure.in,
13896 so that aclocal 1.4 works.
13897 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13899 2002-01-28 Akim Demaille <akim@epita.fr>
13901 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13904 2002-01-28 Akim Demaille <akim@epita.fr>
13906 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13907 AUTOTEST_PATH *after* it was set.
13908 Don't put `.' in the PATH: the user should be precise and `./' if
13909 needed. In addition, given that the test suite does some `cd', if
13910 `.' is in the path, the `tested programs' sections will report
13911 programs found in the test suite's directory, while during the
13912 tests (performed in their own directory), these programs are no
13913 longer visible. In other words, the results is confusing and
13915 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

13924 * doc/autoconf.texi: Finally add Akim as an author.
13926 2002-01-24 Akim Demaille <akim@epita.fr>
13928 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13929 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13930 Bourne. Use /bin/sh.
13931 From Andreas Buening.
13933 2002-01-24 Akim Demaille <akim@epita.fr>
13935 * config/config.guess, config/config.sub, config/texinfo.tex:
13936 Update from masters.

13959 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13960 message on invalid options.
13961 * bin/autom4te.in (parse_args): Don't use
13962 Autoconf::General::getopt with non valid options.
13964 2002-01-17 Jim Meyering <meyering@lucent.com>
13966 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13967 $ac_cv_exeext so we don't use an old, invalid, cached value.
13969 2002-01-11 Akim Demaille <akim@epita.fr>

13980 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13981 package.m4, since is really depends upon configure.ac, not
13983 * doc/autoconf.texi (testsuite Scripts): Adjust.
13984 * tests/Makefile.am (package.m4): New.
13985 EXTRA_DIST it since its a source.
13987 2002-01-06 Akim Demaille <akim@epita.fr>
13989 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13990 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13991 and PACKAGE_BUGREPORT from here...
13992 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13994 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13995 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13996 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13997 * tests/tools.at (autoheader): Adjust.
13998 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
14000 2002-01-06 Akim Demaille <akim@epita.fr>

14017 * doc/autoconf.texi (New Macros): Tweak wording.
14019 2001-12-14 Akim Demaille <akim@epita.fr>
14021 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
14022 trailing files, don't apply `-rf' to files which might not be
14023 created by configure (core, core.*, and *.core), but just `rm -f'.
14024 Suggested by Jonathan Kamens.
14026 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
14028 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
14030 2001-12-14 Akim Demaille <akim@epita.fr>
14032 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
14034 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
14036 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
14037 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
14038 abs_srcdir, top_srcpath to abs_top_srcdir.
14039 (_AC_OUTPUT_FILES): Adjust.
14040 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
14041 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
14042 * tests/wrappl.in, tests/wrapsh.in: Adjust.
14044 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

14050 2001-12-12 Kevin Ryde <user42@zip.com.au>
14052 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
14053 forbidden file descriptors table.
14055 2001-11-26 Akim Demaille <akim@epita.fr>
14057 * bin/autoscan.in (%c_keywords): Build it at top level.
14058 Map to 1 in order to simplify its uses.
14060 2001-11-26 Akim Demaille <akim@epita.fr>
14062 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
14063 Remove $filepath, useless.
14064 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
14065 variables, they are really part of the tokens.
14066 Split the input line on spaces and then look for tokens.
14067 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
14068 because of `lex$U.$(OBJEXT)'.
14069 (&scan_files): Use "@list" instead of join.
14070 * doc/Makefile.am (CLEANFILES): Add *.fns.

14075 Remove, replaced by...
14076 * tests/wrappl.in: Be common for all the Perl executables.
14077 In particular autoscan and autoheader want -I.
14078 * configure.ac: Adjust.
14079 * lib/autoscan/headers: errno.h is portable.
14081 2001-11-26 Akim Demaille <akim@epita.fr>
14083 * bin/autoscan.in (used): New.
14086 2001-11-26 Akim Demaille <akim@epita.fr>
14088 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
14090 (&scan_sh_file): Remove a duplicate pattern.
14091 (&check_configure_ac): Use long options.
14092 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

14097 Before, having a line containing the opening of a multi line
14098 comment made the whole line be ignored.
14100 2001-11-26 Akim Demaille <akim@epita.fr>
14102 * doc/autoconf.texi (Using an Autotest Test Suite): New.
14103 (testsuite Scripts): Be one of its subsection.
14104 (Autotest Logs): New.

14108 Test groups are now run two directories deeper.
14110 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
14111 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
14113 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
14114 top_srcdir, builddir and top_builddir.
14115 Use `at_*dir' relatively to the directory containing the
14116 suite, use `*dir' when relatively to the current group dir.
14118 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14120 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14121 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14122 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14125 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14127 * doc/autoconf.texi (Using System Type): Add an example of `case
14128 $host' usage so people quit using `case $target' everywhere.
14130 2001-11-22 Akim Demaille <akim@epita.fr>
14132 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14133 spotted by Jim Meyering.
14135 2001-11-16 Paul Eggert <eggert@twinsun.com>
14137 This patch implements a `long double' suggestion by Oliver Kiddle.
14139 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14140 static, to catch errors if the value isn't known at compile-time
14141 and the compiler supports dynamic arrays. Change its name from
14142 `_array_' to `test_array' to avoid potential name clashes.
14143 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14144 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14145 better than double. Catch a bug in GCC 2.95.2 x86.
14146 * doc/autoconf.texi (C Compiler): Document the above.
14149 2001-11-13 Akim Demaille <akim@epita.fr>
14151 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14153 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14155 2001-11-13 Akim Demaille <akim@epita.fr>
14157 * lib/autotest/general.m4 (AT_INIT): After having run the test
14158 group, go back to the initial directory, not to at_suite_dir.
14160 2001-11-13 Akim Demaille <akim@epita.fr>
14162 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14163 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14164 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14166 (AT_CHECK_CONFIGURE): Use absolute paths.
14167 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14168 The problem is still the old one: there is no means in M4 (that I
14169 know about) to create a defining macro, because there is no means
14170 to create `$1' etc., therefore, the defining macro ``swallows''
14171 all the arguments meant to the defined macro.
14173 2001-11-13 Akim Demaille <akim@epita.fr>
14175 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14176 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14178 * tests/aclocal.m4: Remove, as it is no longer used.
14180 2001-11-13 Akim Demaille <akim@epita.fr>
14182 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14183 variable names when referring to a single test group, or to
14184 `suite' when referring to the whole test suite.
14185 `at_last_test' is removed: m4 compute at_format itself.
14186 (at_stdout, at_stder1, at_stderr): New variables.
14187 (AT_CHECK): Use them.
14189 2001-11-13 Akim Demaille <akim@epita.fr>
14191 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14193 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14194 Do it as soon as a test fails, don't wait till the end of the test
14196 Don't remove $as_me.[0-9]*, since these files no longer exist.
14198 2001-11-13 Akim Demaille <akim@epita.fr>
14200 * tests/tools.at: Use absolute paths, since we are no longer run
14203 2001-11-13 Akim Demaille <akim@epita.fr>
14205 Now that tests are running in their own private dir, there is no
14206 need to list the files to remove at the end of tests groups.
14208 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14209 (AT_data_files, at_data_files): Remove.
14210 (AT_CLEANUP, AT_DATA): Simplify.
14212 Remove the group dir if !debug && !failed.
14213 * tests/atspecific.m4: Adjust.
14215 2001-11-13 Akim Demaille <akim@epita.fr>
14217 Start a new layout for Autotest: `testsuite' creates
14218 `testsuite.dir' in which the at-check-line etc. files are to be
14219 found, and `testsuite.dir/003' where the test group 3 is run.
14221 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14222 at_check_line_file, at_format, at_test_normalized, at_group_dir
14224 Create the directories.
14225 Use absolute paths for at- files.
14226 (AT_CHECK): Adjust.
14228 2001-11-11 Michael Matz <matz@kde.org>
14230 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14232 (m4_car): Properly quote arguments.
14234 2001-11-13 Akim Demaille <akim@epita.fr>
14236 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14237 with stricter rules on LIBOBJS.
14239 2001-11-12 Paul Eggert <eggert@twinsun.com>
14241 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14242 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14245 2001-11-12 Akim Demaille <akim@epita.fr>
14247 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14249 2001-11-12 Akim Demaille <akim@epita.fr>

14252 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14253 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14254 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14255 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14256 specify to what the macro should be defined (typically to 1).
14258 2001-11-12 Akim Demaille <akim@epita.fr>
14260 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14263 2001-11-12 Akim Demaille <akim@epita.fr>
14265 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14266 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14267 definition used by Automake where LEX is +/- "${missing} lex" and
14268 `missing' itself contains variables.
14270 2001-11-12 Akim Demaille <akim@epita.fr>
14272 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14273 Now that M4sh pushes BODY, the comments were output at the end of
14276 2001-11-08 Akim Demaille <akim@epita.fr>
14278 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14279 that we can trace macros from aclocal.m4.
14280 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14281 obsoleted, and redirect to the former anyway.
14282 Reported by Ralf Corsepius.
14284 2001-11-08 Akim Demaille <akim@epita.fr>
14286 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14287 processed only if present.
14288 * tests/torture.at (Configuring subdirectories): Use autoreconf
14289 instead of successive calls to autoconf.
14290 Add a nonexistent subdirectory to exercise the patch above.
14291 Reported by Ralf Corsepius.
14293 2001-11-08 Kevin Ryde <user42@zip.com.au>
14295 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14296 doesn't accept .S files.
14298 2001-11-07 Akim Demaille <akim@epita.fr>

14304 (handle_output): Use it.
14305 Read m4_pattern_forbid with messages.
14307 2001-11-05 Akim Demaille <akim@epita.fr>
14309 * bin/autom4te.in (--normalize): Remove.
14310 * lib/autom4te.in: Adjust.
14312 2001-11-05 Akim Demaille <akim@epita.fr>
14314 * tests/Makefile.am (testsuite): Rename this target as...
14315 ($(TESTSUITE)): this.
14318 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14320 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14321 the --prefix option, also remove it's argument.
14323 2001-11-05 Akim Demaille <akim@epita.fr>
14325 * doc/autoconf.texi (testsuite Invocation): Update.
14326 (Writing testsuite.at): Update.
14328 2001-11-03 Akim Demaille <akim@epita.fr>

14335 (&file_name_is_absolute): New, wrappers around routines from
14337 Use and export them.
14338 (&find_configure_ac): Optionally take a directory where to look at.
14339 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14341 Default @ARGV to `.', not find_configure_ac.
14342 (&autoreconf): Argument is a directory.
14343 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14344 * doc/autoconf.texi (autoreconf Invocation): Update.
14346 2001-11-03 Akim Demaille <akim@epita.fr>

14350 Add basename, dirname, and fileparse.
14352 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14353 Don't look for aclocal flags if we already know aclocal is not
14355 Move aclocal.m4t only if it exists.
14356 Reported by Ezra Peisach.
14358 2001-11-03 Akim Demaille <akim@epita.fr>
14360 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14361 passed on command line, defaulting to ./configure.ac if present.
14362 (&maybe_autoreconf, File::Find): Remove, unused.
14363 (&autoreconf): If autoconf is not used, don't try to trace.
14365 2001-11-02 Akim Demaille <akim@epita.fr>
14367 * configure.ac: Bump to 2.52g.
14369 2001-11-02 Akim Demaille <akim@epita.fr>
14373 2001-11-02 Akim Demaille <akim@epita.fr>
14375 * config/config.guess, config/config.sub, doc/standards.texi:
14376 * config/lispdir.m4: Update from masters.
14377 * configure.ac: Bump to 2.52f.
14379 2001-11-02 Akim Demaille <akim@epita.fr>
14381 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14382 Don't run aclocal when aclocal.m4 is not from aclocal.
14384 Don't run libtoolize and gettextize if --install is not given.
14386 2001-11-01 Paul Eggert <eggert@twinsun.com>
14388 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14389 be invoked before _AS_LINENO_PREPARE.
14390 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14391 than character ranges.
14393 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14394 invoking AS_BASENAME. Set the locale variables to 'C' if
14395 possible, as POSIX requires this to get the traditional
14397 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14399 2001-10-31 Paul Eggert <eggert@twinsun.com>
14401 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14402 with {}, as that triggers a bug in Bash 2.05.
14404 (_AS_LINENO_PREPARE): Use Sed rather than
14405 Awk. Fix the sed prepass to work even if there are multiple
14406 instances of $LINENO on the same line. Do not substitute for
14407 other variables like $LINENOT. Do not check file dates; such a
14408 check is unreliable on sufficiently fast machines, and removing
14409 the check makes the code simpler and more reliable. Check for
14410 output and chmod failures.
14412 * doc/autoconf.texi (Special Shell Variables): Document
14415 2001-10-31 Akim Demaille <akim@epita.fr>
14417 * tests/Makefile.am (atconfig): Remove this target, Automake
14420 2001-10-31 Akim Demaille <akim@epita.fr>
14422 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14423 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14424 provided, while it is optional.
14425 * configure.ac: Adjust.
14427 2001-10-26 Paul Eggert <eggert@twinsun.com>
14429 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14430 lib/Autom4te/Struct.pm:
14431 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14434 * doc/autoconf.texi (Special Shell Variables): Document some
14435 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14437 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14438 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14439 eval $LINENO is not portable in practice.
14441 2001-10-24 Akim Demaille <akim@epita.fr>
14443 * lib/Autom4te/General.pm (backname): New.
14445 2001-10-24 Akim Demaille <akim@epita.fr>

14453 2.05's use of ANSI quoting in its `set' builtin.
14455 2001-10-22 Paul Eggert <eggert@twinsun.com>
14457 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14458 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14459 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14460 POSIX decided to standardize on the int flavor of strerror_r.
14461 Always do char* test, as there's no reason not to.
14462 Assign to a char* var, to catch strerror_r that returns int*.
14464 * doc/autoconf.texi (Particular Functions):
14465 Document the above changes. Also, document the fact that
14466 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14468 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14470 2001-10-20 Akim Demaille <akim@epita.fr>
14472 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

14475 2001-10-20 Akim Demaille <akim@epita.fr>
14477 * lib/Autom4te/General.pm (&update_file): If destination is
14478 unchanged, remove the source.
14479 (&up_to_date_p): Don't be verbose, be debug.
14480 * bin/autoreconf.in: No longer support --m4dir.
14481 (&autoreconf): Display the full path of the configure.ac we are
14483 Trace it only once.
14484 Be sure to honor --force with gettextize.
14485 Always run aclocal.
14486 * doc/autoconf.texi: Adjust.
14488 2001-10-20 Akim Demaille <akim@epita.fr>
14490 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14492 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14493 `intl' is already present, as it refuses unless --force.
14494 (&parse_args): Use -I, --include instead of the old Autoconf
14496 ($localdir, $autoconf_dir): Remove.
14498 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14500 2001-10-19 Jens Petersen <petersen@redhat.com>
14502 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

14515 comment, explain how to install automatic mode selection.
14518 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14520 * bin/autoreconf.in (autoreconf): Display the path to the
14521 configure.ac being studied.
14523 2001-10-18 Paul Eggert <eggert@twinsun.com>
14525 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14526 long, to work around a bug in the HP C compiler version HP92453-01
14529 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14530 (AS_BASENAME_EXPR): New macro.
14531 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14532 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14533 and fall back on 'sed' only if the other two fail. This makes
14534 AS_BASENAME act more like AS_DIRNAME.
14535 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14536 contains white space.
14537 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14538 Use AS_DIRNAME, since I think it's now DOS-friendly.
14539 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14540 Allow "dirname //FOO" to return either / or //, as POSIX allows
14543 2001-10-10 Akim Demaille <akim@epita.fr>
14545 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
14546 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.

14551 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14552 m4_define, since...

14555 2001-10-10 Akim Demaille <akim@epita.fr>
14557 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

14589 (Syntax of the shell scripts): Don't.

14591 bother with $force since...
14592 * lib/Autom4te/General.pm: does.
14594 2001-10-08 Akim Demaille <akim@epita.fr>
14596 * bin/autoreconf.in: Rewrite in Perl.
14597 * configure.ac: Adjust.

14666 include handle the m4_pattern_*, no longer push the

14681 empty, and if we can find a shell that does support LINENO,
14682 then set CONFIG_SHELL to that shell and then re-execute
14683 ourselves with CONFIG_SHELL.
14685 2001-10-05 Paul Eggert <eggert@twinsun.com>
14687 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
14688 doesn't exist. Remove *.tmp, as a .tmp file is created during the

14758 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
14759 Don't use nested parenthesization. This patch was originally
14760 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
14761 but somehow it didn't get incorporated then.
14762 * doc/autoconf.texi (Limitations of Usual Tools):

14765 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
14766 Report an error if the size cannot be determined even though
14768 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14769 Check for `expr' arithmetic overflow, and for compilation failure,
14770 and invoke a new argument $4 if either is discovered.
14771 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14772 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
14774 2001-09-28 Akim Demaille <akim@epita.fr>
14776 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

14805 (AC_PROG_CPP requires AC_PROG_CC): here and...
14806 * tests/fortran.at (GNU Fortran 77): there.
14807 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14808 AC_TRY_RUN is about compilation, not shell commands.
14809 (Test Programs): AC_TRY_RUN works as used to be advertised.
14811 2001-09-27 Akim Demaille <akim@epita.fr>
14813 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by

14990 * lib/autotest/general.m4: Englishoes.
14991 From Tim Van Holder and Alexey Mahotkin.

14995 * doc/autoconf.texi (Common Shell Constructs): New node,
14996 documenting AS_DIRNAME.
14997 (Limitations of Usual Tools): Refer to it when discussing dirname.
14998 Also, update discussion of POSIX standard to reflect latest draft.

15001 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
15003 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
15004 Do not pass a first argument with leading '-'
15005 to expr, by parenthesizing initial integers that might be negative.
15007 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
15008 now merely checks whether it is an error to pass an argument
15011 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
15012 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
15013 whether it is a (compile-time) error to pass an argument to

15015 and is all that AC_FUNC_GETPGRP's users really need.
15017 2001-09-18 Akim Demaille <akim@epita.fr>

15031 Add test for AS_BASENAME.
15032 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
15033 added test. It now correctly handles /1/2/3/, returning '3' not ''.
15034 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
15035 * tests/base.at: Fixed the expected responses. The old ones were
15037 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
15038 the documentation claims it should (and how it behaved in 2.13).
15040 2001-09-18 Akim Demaille <akim@epita.fr>
15042 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
15043 the AC_CONFIG_COMMANDS invocation.
15044 This also solves the name clash problems.
15045 Don't set the package's ID.
15046 * lib/m4sugar/Makefile.am (version.m4): Revamp.
15047 No longer to be shipped.
15048 (version.in): Remove.

15051 Use `m4_PACKAGE_STRING'.
15052 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
15053 the only optional argument is the name of the test suite.
15054 Expect `package.m4' to define the package signature.
15055 * lib/autom4te.in (Autotest): Add `package.m4?'.
15056 * tests/Makefile.am (package.m4): New.
15057 * tests/suite.at: ifnames is a victim.

15062 AC_LIBSOURCE, AC_CONFIG_FILES.

15076 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15077 Always include <stdio.h> and <stdlib.h>. Evaluate
15078 the expression in an extra function before these includes. Call
15079 fprintf "%d" only after ensuring the argument is of type 'int'.
15080 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
15082 2001-09-17 Paul Eggert <eggert@twinsun.com>
15084 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
15085 or CFLAGS=-O5. In that case, the linker has a relaxed view of
15086 fatal errors, and AC_CHECK_LIB causes it to include libraries even
15087 when they don't exist.
15089 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
15090 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
15093 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
15094 version with the version used by fileutils 4.1, except use
15095 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
15098 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.

15140 * lib/autotest/general.m4 (AT_INIT): Create and remove
15141 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15142 test suites can cohabit.

15146 * tests/mktests.sh: Don't output banners for empty test files.

15252 2001-09-05 Akim Demaille <akim@epita.fr>
15254 Be ready to handle filenames as stupid as `dnl.at', for if even
15255 the maintainer is dumb enough to do that...
15257 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15258 excellence in M4 quotation: consider `__file__' is active.
15260 And BTW, when invoking m4, pass the --include in the right order:

15290 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
15291 New, extracted from main.
15292 Use IO::File wherever possible.
15293 (input.m4): Be constant, use -I instead of hard coding $tmp.
15294 Therefore be a quoted heredoc.
15295 Don't invoke `_au_disable', since ac was not loaded, but just

15312 Reported by Nicolas Joly.

15321 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
15323 2001-08-31 Akim Demaille <akim@epita.fr>
15325 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
15326 (testsuite Scripts): There is no such thing as `atconfig.in'.
15327 And actually one diagram is missing: test suite runtime.
15329 2001-08-31 Akim Demaille <akim@epita.fr>
15331 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
15334 2001-08-31 Akim Demaille <akim@epita.fr>
15336 * bin/autoupdate.in (@include): `installcheck' revealed the path
15337 to m4sugar was lacking!
15339 2001-08-31 Akim Demaille <akim@epita.fr>
15341 * man/Makefile.am (.x.1): We really have to pass
15342 autom4te_perllibdir.

15346 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

15352 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
15353 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
15354 Use directly autom4te, not autoconf.
15355 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
15357 2001-08-31 Akim Demaille <akim@epita.fr>
15359 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

15379 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
15380 (autoheader): Pass --force since the test suite goes too fast for
15382 Adjust to the new autoheader messages.
15384 2001-08-31 Akim Demaille <akim@epita.fr>
15386 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

15395 * bin/autoupdate.in, bin/autoheader.in: Adjust.
15396 Drop AC_MACRODIR dead for real.
15397 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15398 `autoheader: `config.hin' is created'.
15399 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15401 2001-08-31 Akim Demaille <akim@epita.fr>
15403 * bin/autoheader.in: Rewrite in Perl.
15404 * tests/autoheader: Adjust.
15406 2001-08-31 Akim Demaille <akim@epita.fr>
15408 * bin/autoconf.in (--include, -I): New option.
15409 Map --localdir, --autoconf-dir onto it.
15410 Forward autom4te's options instead of interpreting them.
15411 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15412 There is no such envvar since the inception of autom4te.cfg.
15413 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15414 * bin/autoupdate.in: Adjust, and perform more control.
15415 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15416 * tests/autoconf: Dittowise.
15418 2001-08-31 Akim Demaille <akim@epita.fr>
15420 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15421 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15423 Use -e, not -f, since /dev/null for instance is OK.
15424 (&parse_args): Adjust.
15425 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15427 2001-08-31 Akim Demaille <akim@epita.fr>

15430 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,

15432 installed peer executables, only PATH is allowed to resolve it.
15433 Pass `autoconf_dir' via options, not via invisible envvars.
15434 * lib/Autom4te/General.pm (&find_peer): Remove.
15435 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15436 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15437 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15438 find the executables for it.
15439 * tests/Makefile.am: Major cleanup. Too lazy to document...
15440 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15442 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15443 indeed related to running the test suite, while passing
15444 --autoconf-dir and others is related to running non installed
15445 Autoconf executables. So don't do that, leave it to...
15446 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15447 * tests/autoscan: New.
15448 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15449 refer to library files: rely on --language.

15453 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

15464 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15465 Suggested by Paul Eggert.
15467 2001-08-29 Akim Demaille <akim@epita.fr>
15469 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15470 download in a tmp dir.
15472 2001-08-29 Akim Demaille <akim@epita.fr>
15474 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
15475 case insensitive OSes out there :(

15494 foo=`(command) 2>/dev/null`

15644 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15645 the name of the directory they're in, instead of the filename,

15856 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

15874 * doc/autoconf.texi: Work around Texinfo buglets.
15875 (Transformation Rules): One example is enough, users are expected
15876 to have their brains on. And BTW, use DESTDIR.
15877 (dvar): New macro. Use it.
15879 2001-08-17 Akim Demaille <akim@epita.fr>
15881 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15934 autom4te.cache (it's a directory, not a file.
15935 * Makefile.am: Ditto (but maintainer-clean-local).
15937 2001-08-15 Akim Demaille <akim@epita.fr>
15939 * bin/autom4te.in (@m4_warning): New.
15940 (&handle_m4): Use it.
15941 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15942 warnings are issued at each run.
15943 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15944 is in the src tree.
15946 2001-08-15 Akim Demaille <akim@epita.fr>
15948 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15949 don't waste time running `autoupdate --version' works.
15950 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15952 2001-08-13 Akim Demaille <akim@epita.fr>

16011 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
16013 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
16014 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
16015 * doc/autoconf.texi (C Compiler Characteristics): Update
16016 documentation for AC_C_BIGENDIAN.
16018 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

16021 magic values from an object file when cross-compiling.
16022 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
16024 2001-08-10 Akim Demaille <akim@epita.fr>
16026 * bin/autom4te.in (&handle_output): Don't use `grep' with side
16028 Suggested by Russ Allbery.
16030 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
16032 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
16033 current $prefix to the sub-configures.
16035 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
16037 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
16038 extension (needed on BeOS). Reported by Guido van Rossum.
16040 2001-08-09 Akim Demaille <akim@epita.fr>
16042 * bin/autom4te.in ($icache): Load it only if older than autom4te.
16044 2001-08-07 Akim Demaille <akim@epita.fr>
16046 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
16048 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
16049 No need to remove the files before and after the each test, before
16050 each test and at the end of the suite is enough.
16051 Display only the children `times', not the shell's.
16052 If the test failed or was skipped, at-times is not available.
16054 2001-08-07 Akim Demaille <akim@epita.fr>
16056 Always produce testsuite.log, including when there are no
16057 failures. This helps getting information on skipped tests, and
16058 duration of the tests. Err, implement the latter btw.
16060 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
16061 Dump information on the first run of each test.
16062 (AT_CLEANUP): Create `at-times' containing the duration of the
16065 2001-08-07 Akim Demaille <akim@epita.fr>
16067 The use of `dumpstat' revealed that `len' was used although it
16068 should not. m4_text_wrap was using it, but in the Autoconf world
16069 where it is legal. Hence (i) test M4sh in its own world, not
16070 Autoconf's, and (ii), ahem, fix the bug :)
16072 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
16073 does not like `' instead of [].
16074 (AT_INIT): Forbid `^_?AT_'.
16075 And don't output such tokens.
16076 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
16077 `script.as', and `autom4te.cache'.
16078 Remove `empty' and `macro' which are no longer used.
16079 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
16080 * tests/m4sugar.at: Use it.
16081 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
16083 2001-08-07 Akim Demaille <akim@epita.fr>
16085 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
16087 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
16089 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
16091 2001-08-04 Akim Demaille <akim@epita.fr>
16093 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
16094 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
16096 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
16097 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
16098 (AC_F77_MAIN): Likewise.
16100 2001-08-04 Akim Demaille <akim@epita.fr>
16102 Don't rely on M4sugar outputting the patterns in files, since we
16103 might process the output _without_ running m4, hence without these
16106 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
16107 * bin/autom4te.in (@Request::includes): Remove, unused.
16108 (@Request::source): Rename as...
16109 (@Request::input): this.
16110 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
16111 (&handle_output): Fetch the patterns from the traces.
16112 `$forbidden' and `$allowed' are constant: use m//o.
16113 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
16114 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
16116 2001-08-04 Akim Demaille <akim@epita.fr>
16118 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
16119 autoconf', i.e., in addition to caching traces, cache the output.
16121 * bin/autom4te.in (Request::cache): Rename as...
16122 (Request::id): this.
16123 ($cache, $icache, $tcache, $ocache): New.
16124 (&handle_m4): Save M4 output in the cache instead of $tmp.
16125 (&handle_output): Adjust.
16126 (&up_to_date_p): Check that the output cache is up to date too.
16127 (top level): Run `&handle_m4' iff force or the cache is invalid.
16128 Run `&handle_output' if the output cache is more recent.
16130 2001-08-04 Akim Demaille <akim@epita.fr>
16132 * bin/autom4te.in ($force): New.
16133 (&parse_args, &print_usage): -f, --force is a new option.
16134 (&handle_output): CPP directives might have spaces after `#'.
16135 (&parse_args): The first file only can be frozen.
16137 2001-08-04 Akim Demaille <akim@epita.fr>
16139 Don't let autom4te compute the `include' traces several times:
16140 first check that the trace cache file is up to date, and then
16141 compare its timestamp with that of the output.
16143 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16144 the preamble. Don't require 5.005 as Autom4te::General does it,
16145 and better yet (use `use', not `require'!).
16146 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16147 Class::Struct as Autom4te::Struct.
16148 * lib/Autom4te/General.pm (File::stat): Use it.
16149 (&mtime): New, export it.
16150 * bin/autom4te.in: Use it.
16151 Declare `$req' is invalid if it is outdated.
16152 Don't declare it valid before saving it if something went wrong.
16154 2001-08-04 Akim Demaille <akim@epita.fr>
16156 Autom4te shall not encode Autoconf data, and preselecting traces
16157 must be proposed to the users.
16159 * bin/autom4te.in (@required_trace): Remove.
16161 (&parse_args, &print_usage): -p, --preselect is a new option.
16162 (&up_to_date_p): Adjust.

16167 * tests/tools.at (autoconf --trace: user macros): Check traces on
16168 macros invoked without arguments, and macros invoked with multiple

16176 2001-08-03 Akim Demaille <akim@epita.fr>
16178 * bin/autoconf.in ($@): Work around the usual sh bug.
16181 2001-08-03 Akim Demaille <akim@epita.fr>
16183 Clean up the handling of the M4 builtins tracing exception.
16185 * bin/autom4te.in (Request::request): Don't complete M4 builtins

16188 (@m4_builtin): this.
16189 (%m4_builtin_alternate_name): New.
16190 (&parse_args): Complete the trace requests with alternate names.
16191 (&handle_traces): Hence no longer do it here.

16196 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
16197 m4_if, and m4_wrap.
16199 2001-08-03 Akim Demaille <akim@epita.fr>
16201 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
16202 (m4_divert_pop): Dump the whole diversion stack when a diversion
16204 * bin/autom4te.in (&handle_output): Remember of the first
16205 occurrence of a possibly undefined macro, not the last.
16206 Complain about the possibly undefined macros in the same order as
16207 the appear in the output.
16208 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
16209 * tests/tools.at (autoconf: forbidden tokens, basic)
16210 (autoconf: forbidden tokens, exceptions): No longer sort
16211 autoconf's stderr, as it is now deterministic.
