1946 (Keywords and ranges): Add test for missing -k argument.
1947 * NEWS: Document this.
1948 * doc/autoconf.texi (testsuite Invocation): Likewise.
1950 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1952 * build-aux/config.guess, build-aux/config.sub,
1953 build-aux/texinfo.tex: Sync from gnulib.
1954 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
1955 Likewise.
1957 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1959 * doc/autoconf.texi (Particular Programs): Do not mention the
1960 Autoconf version in which the AC_PROG_INSTALL change was done.
1961 Suggested by Paul Eggert.
1963 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1965 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1966 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1967 mode, we change to the source directory, also set $ac_pwd so we
1968 do not go back to the build tree for the next config subdir.
1969 * tests/torture.at (Deep Package): Extend test to contain two
1970 config subdirs on the top level.
1972 Fix parallel `maintainer-check'.
1973 * Makefile.am (maintainer-check-tests): Depend on `all'.
1974 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1975 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1976 Likewise.
1977 (maintainer-check): Serialize the testsuite runs.
1979 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
1980 in feature string for --enable/--with. Convert to underscore
1981 for variable name.
1983 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
1984 `install -c file1 file2 dir' works.
1985 * doc/autoconf.texi (Particular Programs): Document this.
1986 * NEWS: Update.

1995 Reported by Reuben Thomas.
1997 2008-01-15 Eric Blake <ebb9@byu.net>
1999 * lib/m4sugar/m4sugar.m4 (m4_qlen): Use fewer macros.
2001 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2003 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
2004 check_SCRIPTS. Building the wrappers for `all' allows help2man
2005 to use them for the manpages.
2006 Report by Benoit Sigoure.
2008 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
2010 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2012 Fix some write failure cases in Autotest.
2013 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
2014 upon write failures for --help, --version, --list.
2015 Guard against write failures for intermediate created scripts.
2016 <at_func_create_debugging_script>: Do not make the debugging
2017 script executable if it is not complete.
2019 2007-12-12 Eric Blake <ebb9@byu.net>
2021 Fix thinko in earlier patch - m4_join isn't defined yet.
2022 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
2023 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
2024 (m4_require): Use m4_do, not m4_join.
2026 Fix some whitespace tests on cygwin.
2027 * tests/tools.at (autom4te and whitespace in file names): Restore
2028 font-lock. Create $TMPDIR before it might be used.
2030 Fix spurious testsuite failure with M4 1.4.11.
2031 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
2033 Optimize AC_REQUIRE.
2034 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
2035 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
2036 (m4_require): Avoid extra macro calls.
2038 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2040 * tests/torture.at (srcdir): Fix quoting.
2042 Do not pass top_srcdir to configure scripts in testsuite.
2043 * tests/autotest.at (srcdir propagation): Copy install-sh to
2044 source tree.
2045 (my only test): Drop setting of `top_srcdir'.
2046 * tests/base.at (Input/Output): Likewise.
2047 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
2048 config.guess, and config.sub to test source tree.
2049 Drop AC_CONFIG_AUX_DIR setting.
2050 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
2051 * tests/torture.at (Substitute a 2000-byte string): Drop
2052 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
2053 (Substitute a newline, datarootdir workaround): Likewise.
2054 (Define a newline): Adjust for linenumber changes in configure.ac.
2055 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
2057 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
2058 if `pwd` contains whitespace.
2060 Quote $abs_top_srcdir in tests.
2061 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
2062 * tests/tools.at (Syntax of the shell scripts): Likewise.
2064 * tests/m4sh.at (LINENO): Quote $0.
2066 Fix testsuite program wrapper for whitespace in `pwd`.
2067 The problem here is that the usual mantra is that command
2068 variables can contain arguments, thus we cannot just escape
2069 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
2070 $top_builddir/tests directory early in $PATH, so that the
2071 wrappers are found by their plain name.
2072 * tests/wrapper.as: Put $testdir early in $PATH.
2073 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
2075 Proper config.status --file/--header and $srcdir escaping.
2076 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
2077 characters in $ac_file_inputs.
2078 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
2079 accordingly.
2080 * tests/torture.at (datarootdir workaround): Adjust.
2081 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
2083 Fix Autotest for whitespace in `pwd`.
2084 * lib/autotest/general.m4 (AT_INIT)
2085 <at_func_create_debugging_script, Driver Loop>:
2086 Quote $at_group_dir.
2087 * tests/autotest.at (whitespace in absolute testdir): New test.
2089 * lib/autom4te.in: Quote @datadir@.
2091 Proper file name escaping in Autoconf programs and Perl modules.
2092 This includes escaping of characters special to the shell
2093 as well as special to Perl, e.g., leading `<' or `>'.
2094 For example, when $file starts with `>', `open ">$file"'
2095 wrongly tries to append to a different file.
2096 * bin/autoconf.as: Fix quoting for autom4te options.
2097 * lib/Autom4te/General.pm (shell_quote): New function, taken
2098 from coreutils, written by Jim Meyering.
2099 (mktmpdir): Use it.
2100 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
2101 and open_quote.
2102 * bin/autoreconf.in (parse_args): Likewise.
2103 * bin/autoscan.in (main): Likewise.
2104 * bin/autoupdate.in (main): Likewise.
2105 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
2106 * bin/ifnames.in: Likewise, XFile usage fixes.
2107 * tests/tools.at (autom4te and whitespace in file names): Extend
2108 test. Test twice, with special characters allowed on w32, and the
2109 rest. Test leading and trailing whitespace, for `open_quote'.
2110 (autotools and whitespace in file names): New, analogous test.
2111 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
2112 by Russ Allbery and Eric Blake.
2114 Sync from Automake.
2115 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
2116 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
2117 * lib/Autom4te/FileUtils.pm (open_quote): New function.
2118 (update_file, contents): Use it.
2120 * Makefile.am (autom4te-update): Rewrite for git.
2122 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2124 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
2126 Fix copyright years.
2127 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
2128 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
2130 2007-12-04 Eric Blake <ebb9@byu.net>
2132 Manually resync with gnulib, since 'make cvs-update' no longer works.
2133 * build-aux/config.guess: New upstream version.
2134 * build-aux/config.sub: Likewise.
2136 When using older automake, don't downgrade build-aux/texinfo.tex.
2137 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
2138 * doc/Makefile.am (TEXINFO_TEX): Add.
2140 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2142 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2143 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2144 #undef as this runs afoul of our new way of creating config.h.
2145 Problem reported by Jim Meyering in
2146 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2148 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2150 Fix autom4te for unusual characters in input file names.
2151 * bin/autom4te.in (files_to_options): Quote active characters
2152 for the shell.
2153 * tests/tools.at (autom4te and white space in file names):
2154 New test.
2156 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2157 Document that Tru64 awk always splits $0.
2159 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2161 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2162 `#AT_STOP_...' line at the end of each test.
2164 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2166 * lib/autotest/general.m4 (AT_INIT): For awk line number
2167 extraction script, ensure `$at_group' has a defined value
2168 even for the empty set, and properly quote its usage inside
2169 the awk script.
2171 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2173 * doc/autoconf.texi (Shell Functions): New chapter. Document
2174 IRIX sh $0 issue in functions, move content from ...
2175 (Portable Shell): ... here.
2176 (Shell Script Compiler): Note that shell functions are not
2177 totally unportable any more.
2179 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2180 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2182 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2183 extracting the line numbers of the last needed test.
2185 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2187 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2188 Fix quoting.
2190 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2192 Fix IRIX testsuite debugging failures: $0 in functions.
2193 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2194 Do not use $0 inside a function, as IRIX sh will set that to the
2195 function name rather than the script invocation name.
2197 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2198 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2200 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2201 to extract test scripts.
2202 (AT_INIT): Extract and cache test script line numbers.
2204 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2206 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2207 subsequent fixups; the awk -> here-document conversion trashes
2208 performance too much with AIX sh.
2210 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2212 * tests/local.at: Do not test m4, perl with AT_TESTED.
2214 Diagnose and guard against write errors dealing with config.status.
2215 The general idea is this: all write failures from `configure'
2216 writing `config.status' are indicated by $ac_write_error, which
2217 is only checked at the end. This is safe because config.status
2218 code is not executed before the file is complete. Other write
2219 failures, be they inside config.status, or in sub shell/awk
2220 scripts spawned from configure or config.status, typically need
2221 earlier checking, as their results are used right afterwards.
2222 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2223 before writing config.status, check afterwards.
2224 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2225 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2226 Set `ac_write_error' for write failures to config.status. Barf
2227 upon write failures to temporary files.
2228 Adjust note about closing and reopening the here-document.
2229 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2230 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2231 reopening the here-document.
2232 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2233 Ensure `ac_write_error' does not escape into config.status.
2234 Also, add a couple of code paths not yet exercised in the test
2235 suite: a config file with input from stdin, and a config header
2236 output to stdout.
2237 Suggestion for catching write errors by Bruno Haible.
2239 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2241 Avoid error with Tru64 awk and testsuite lines with many words.
2242 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2243 reads the testsuite, set the field separator to an unusual value,
2244 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2245 even splits the input if $i, i>0, was never accessed in the script.
2247 Revert 2007-10-17 change.
2248 * TODO: Multiline args in config files and headers mean something
2249 different and are not fixed, see
2250 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2251 Report by Stepan Kasal.
2253 * doc/autoconf.texi (Generic Programs): Fix typo.
2255 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2257 AC_*_TOOL does not canonicalize the prefix
2258 * doc/autoconf.texi (Generic Programs): Do not say that
2259 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2261 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2263 Diagnose write errors in config.status instantiations.
2264 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2265 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2266 on write errors.
2267 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2268 Extend test to also check for some write error failures, using...
2269 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2270 Report by Bruno Haible.
2272 Indentation fixups.
2273 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

2283 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2284 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2286 * lib/autotest/general.m4 (at_func_test): Remove.
2287 (AT_INIT): Pre-extract test groups into separate files.
2288 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.

2290 * tests/autotest.at (Long test source lines): New test.
2292 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2294 Shell functions and variables may share a namespace.
2295 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2296 limitation.
2298 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2300 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2301 gnulib.

2305 * lib/autoconf/status.m4: Fix a couple of comment typos.
2307 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2309 2007-11-13 Jim Meyering <meyering@redhat.com>
2311 Clean up the rule to create "expr".
2312 * tests/Makefile.am (expr): Don't redirect directly to target.
2313 Redirect just once, not for each echo statement.
2314 Use $@, not literal "expr".
2316 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2318 Don't worry about preprocessor when testing long long.
2319 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2320 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2321 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2322 These no longer check for preprocessor flaws.
2323 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2324 Do not check for preprocessor flaws.
2326 2007-11-13 Jim Meyering <meyering@redhat.com>
2328 Adapt dependencies, now that a version change doesn't modify configure.ac
2329 * GNUmakefile: Remove "make clean" kludge.
2330 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2331 configure.ac.
2332 Don't redirect directly to target.
2333 Use $@, not literal "version.m4".
2335 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2337 * doc/autoconf.texi (Making testsuite Scripts): Document
2338 ":;{" shorthand as in previous patch.
2340 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2342 * doc/autoconf.texi (Limitations of Builtins): Document problem
2343 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2344 for the workaround.
2345 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2346 Use ":;{" shorthand.
2347 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2349 2007-11-12 Jim Meyering <meyering@redhat.com>
2351 Add more non-srcdir build support.

2355 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2356 * GNUmakefile (dummy): Remove INSTALL.
2358 Remove racy commands to build scripts in bin/ and tests/.
2359 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2360 are guaranteed to be built, remove the rules that tried to build
2361 them. Before, with a parallel build, these rules could lead to
2362 two processes writing tests/wrapper.in concurrently.
2364 Build in man/ only *after* building in bin/ and tests/.
2365 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2366 in both bin/ and tests/.
2368 Accommodate non-srcdir build-from-checkout.
2369 * build-aux/git-version-gen: Require an additional parameter: $srcdir.

2375 Avoid spurious test failures due to version skew.
2376 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

2408 writable again for the `stderr' file, and ignore errors due to
2409 the attempt to write configure.lineno.
2410 Report by Patrick Welche.
2412 2007-11-10 Jim Meyering <meyering@redhat.com>
2414 Generate package.m4 in build-dir, not srcdir.
2415 * tests/Makefile.am (package.m4): Adjust target.
2416 Don't redirect directly to $@.
2417 (CLEANFILES): Add package.m4.
2418 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2419 in $(srcdir).
2420 When running $(AUTOTEST), search "." before searching $(srcdir).
2422 Avoid a race condition that would make parallel "distclean" fail.
2423 * tests/Makefile.am (distclean-generic): Replace the default,
2424 automake-provided rule with an identical one, but with an additional
2425 dependency on distclean-local. Simply adding the dependency would
2426 cause automake not to emit the rule at all.
2427 * BUGS: Building with -jN works, now.
2429 Distribute git-version-gen.
2430 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2431 since GNUmakefile is distributed, and requires it for dist* rules.
2433 Remove two more generated files from version control.
2434 * INSTALL: Remove generated file.
2435 * lib/autoscan/autoscan.list: Remove generated file.
2437 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2439 * GNUmakefile (PATH): Remove stray apostrophes; they become
2440 part of PATH, which isn't wanted here.
2442 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2444 New config files output variable `top_build_prefix'.
2445 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2446 `top_build_prefix'.
2447 * doc/autoconf.texi (Preset Output Variables): Document it.
2448 * NEWS: Update.
2449 Report by Bob Friesenhahn.
2451 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2452 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2453 function, to parametrize arithmetic with expr vs. the shell.
2454 Use it where possible.
2455 Suggestion by Benoit Sigoure.
2457 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2459 Adjust the documentation of autotest WRT atlocal.
2460 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2461 when using Automake, to write a rule to produce atlocal, since it's
2462 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2463 distributed, not atconfig.in.
2465 2007-11-04 Eric Blake <ebb9@byu.net>
2467 Update list information.
2468 * README: Mention new autoconf-commit list.

2475 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2477 * build-aux/.gitignore: Ignore mkinstalldirs.
2479 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2481 2007-11-03 Jim Meyering <meyering@redhat.com>
2483 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2484 * build-aux/git-version-gen: This syncs from coreutils.
2486 Adjust the build procedure so "make check" works reliably.
2487 * README-hacking: Include an extra step between "make" and
2488 "make check" to ensure that the latter passes.
2490 Use just-built tools, when possible.
2491 * GNUmakefile (PATH): Set and export here, ...
2492 (dummy): ... rather than here.
2494 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2495 and Andreas Schwab <schwab@suse.de>
2497 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
2498 exit status bug.
2500 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2502 * configure.ac (AC_PREREQ): Require version 2.60, for
2503 AC_PROG_SED, AC_PROG_GREP.
2505 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
2506 and Jim Meyering <meyering@redhat.com>
2507 and Andreas Schwab <schwab@suse.de>
2508 and Eric Blake <ebb9@byu.net>
2510 Document a bug in GNU Bash with compound commands and redirections.
2511 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
2512 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
2513 workaround.
2515 2007-11-03 Eric Blake <ebb9@byu.net>
2517 Support m4 1.4.5 in testsuite.
2518 * tests/torture.at (Define a newline): Exclude line numbers in
2519 error message.
2520 Reported by Ralf Wildenhues.
2522 2007-11-03 Jim Meyering <meyering@redhat.com>

2530 Suggestion from Ralf Wildenhues.
2532 2007-11-03 Eric Blake <ebb9@byu.net>

2538 <m4_version_compare>: Document this change.
2539 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
2541 2007-10-30 Bruno Haible <bruno@clisp.org>
2543 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
2544 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
2545 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
2546 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
2547 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
2548 Suggested by Paul Eggert.
2550 2007-10-28 Jim Meyering <meyering@redhat.com>
2552 * README-hacking: Autoconf, Automake, and Perl are required to build.
2553 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
2555 2007-10-28 Jim Meyering <meyering@redhat.com>
2557 README-hacking: Recommend running autoreconf -vi.
2558 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
2559 so that we use just-built tools when they're available.
2560 Suggestions from Ralf Wildenhues.
2562 2007-10-28 Jim Meyering <meyering@redhat.com>
2564 Make inter-release --version output more useful.
2566 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2567 which indicates that it is built using the 19th change set
2568 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2569 is a prefix of the commit SHA1.
2570 * build-aux/git-version-gen: New file.
2571 * configure.ac: Run it to set the version.
2572 (AM_INIT_AUTOMAKE): Don't check NEWS here.
2573 * Makefile.am (dist-hook): Arrange so that .version appears only
2574 in distribution tarballs, never in a checked-out repository.
2575 * .gitignore: Add .version here, too. Just in case.
2576 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
2577 not configure.ac, now that the version number changes automatically.
2579 Ensure that $(VERSION) is up to date for dist-related targets.
2580 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2581 git-version-gen doesn't match $(VERSION), but only for dist targets.
2583 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2585 Fix `Deep Package' failure with a configure script early in PATH

2615 problem reported by Bruno Haible in
2616 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.

2620 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
2621 preprocessor.
2623 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2625 Don't check for bug in HP-UX 11.00 cpp.
2626 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2627 Use -1ull rather than -1u, since that causes problems with gnulib; see
2628 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
2630 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2636 test names.
2638 2007-10-21 Eric Blake <ebb9@byu.net>

2646 escaping of backslash in here-documents.
2648 Fix `Deep Package' test failure on FreeBSD.
2649 * tests/torture.at (Deep Package): Do not add `.' to $PATH
2650 unnecessarily. Do not try running `/bin/sh configure' with a
2651 configure script to be found in $PATH, if the shell does not do
2652 this resolution. Fixes test failure on FreeBSD.
2654 Fix config header generation with AIX awk.
2655 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2656 script, use helper array D_is_set, as `" 0"' does not evaluate

2698 array of banner text from a special diversion.
2699 <PARSE_ARGS_END>: No longer need awk to find banners.
2700 <TESTS>: Banners are no longer processed by main driver loop, so
2701 we no longer need case statement.
2702 (AT_BANNER): Rewrite to populate new diversion.
2703 (AT_SETUP): Each test invokes its own banner. No output is needed
2704 to the TESTS diversion.
2705 * doc/autoconf.texi (Writing Testsuites): Document slight
2706 semantics change.
2707 * tests/autotest.at (AT_BANNERS): Enhance test.

2751 columns.
2752 (TEST_FUNCTIONS): Based on recent changes, rename...
2753 (TEST_GROUPS): ...to this.
2755 Reject FreeBSD m4.

2798 of other write errors.
2799 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
2800 use $as_myself, not $0.
2801 (_AC_INIT_HELP): For --help=recursive, if the subdir does not

3840 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
3841 This fixes a problem introduced on 2000-12-19.
3843 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
3845 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
3846 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
3847 via Bruno Haible.
3849 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
3851 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
3852 AC_CHECK_TYPE, AC_CHECK_TYPES.
3853 * doc/autoconf.texi (Generic types): C types must be type-names
3854 (the C terminology), not type-ids (the C++ term). C++ types
3855 must not be anonymous.
3856 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3857 for C++; this drops support for anonymous struct and union types,
3858 which were problematic anyway.
3859 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
3860 for C++.
3862 2007-04-12 Jim Meyering <jim@meyering.net>
3864 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

3868 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK): Fix AC_CONFIG_LINKS
3869 to prefer a link source from the build tree, if it exists.
3870 Report by Pallav Gupta <pallavgupta@gmail.com>.
3872 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
3874 * doc/autoconf.texi (Generic Types): Document the restrictions
3875 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3876 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3877 with objects too. Document the restrictions on its use.
3878 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3879 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3880 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3881 works but the latter doesn't, then it's a valid type.
3882 This lets people use function types and so forth.
3883 For C++ there doesn't seem to be a simple solution, so leave it alone.
3884 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3885 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3886 AC_CHECK_TYPE; that wasn't documented or necessary.
3888 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3890 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
3891 when cross-compiling.

3911 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
3912 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
3913 default still has the problem. Problem reported by Bruce Korb.

3929 more pitfalls.
3931 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
3933 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
3934 checks for unsigned long long int.
3936 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3938 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3939 nonstandard grep R.E. escape sequences.
3941 2007-03-17 Jim Meyering <jim@meyering.net>
3943 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3944 (Limitations of Usual Tools): Also list \< and \>, and mention that
3945 HP-UX's grep, like the one from Solaris, does not support that syntax.
3947 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3949 * doc/autoconf.texi (Specifying Names): `--host' does not
3950 change the build type.
3952 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3954 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3955 suggests AC_CONFIG_HEADERS.
3956 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

3965 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3966 universal binaries. Problem reported by Elias Pipping.
3968 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3970 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3971 * doc/autoconf.texi (C Compiler): Document this. There is a new
3972 extra argument ACTION-IF-UNIVERSAL.
3973 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3974 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3975 Reindent for sanity's sake.
3977 2007-02-24 Eric Blake <ebb9@byu.net>
3979 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3980 copyright.

3988 status of rm so we know when it failed.
3989 If cleaning of test dir failed before running the test, warn.
3990 Output the line separator in verbose mode before the warning
3991 to make clear the warning belongs to the following test.
3993 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

4008 carriage return.
4009 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
4010 with traditional Awk and begin.
4011 * tests/torture.at (Limitations of Builtins): Document the problem

4045 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
4047 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
4048 latest version.
4049 (Shell Substitutions): Note problems with @{var:=value} etc.
4050 Add a new section for problems with @{#var} etc. Problem noted

4054 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4056 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
4057 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
4058 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
4059 substitution will still be done by the special code.
4060 Report by Jim Meyering.

4079 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
4081 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4083 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
4084 early on the reader side, drop stderr of the input to avoid
4085 `broken pipe' error output; this may happen even with shell
4086 builtin `echo' of some bash versions. Reports by Ian Macdonald
4087 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
4089 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4091 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

4099 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
4101 Fix some wording problems noted by Paolo Bonzini in:
4102 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
4103 * doc/autoconf.texi (Signed Overflow Examples): Give more
4104 discussion about the allow_superuser_privileges example,
4105 and change it a bit to make things clearer.
4106 (Optimization and Wraparound): Clarify whether the compiler
4107 will generate an infinite loop for the example derived from
4108 Autoconf's mktime test.
4109 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
4110 Also, clarify unsigned multiplication overflow.
4112 2007-01-04 Eric Blake <ebb9@byu.net>
4114 * bin/Makefile.am (RELEASE_YEAR): New macro.
4115 (edit): Use it to supply correct copyright year to scripts.
4116 * bin/autoconf.as (version): Use it.
4117 * bin/autoheader.in ($version): Likewise.
4118 * bin/autom4te.in ($version): Likewise.
4119 * bin/autoreconf.in ($version): Likewise.
4120 * bin/autoscan.in ($version): Likewise.
4121 * bin/autoupdate.in ($version): Likewise.
4122 * bin/ifnames.in ($version): Likewise.
4124 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4126 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4127 feedback. The most important changes document what happens when
4128 you convert an out-of-range value to a signed integer type, and
4129 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4130 a + b.
4132 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4133 rewrite, taking notions from the recent discussion on the gcc and
4134 autoconf mailing lists; please see
4135 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4136 and follow the many links.
4137 (Integer Overflow Basics, Signed Overflow Examples):
4138 (Optimization and Wraparound, Signed Overflow Advice):
4139 (Signed Integer Division): New sections.
4141 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4143 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4144 preprocessor macro arguments in traced name.
4145 * doc/autoconf.texi (Defining symbols): Document longstanding
4146 support for AC_DEFINE-ing macros with arguments, and document
4147 behavior when the same variable has multiple AC_DEFINEs.
4148 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4149 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4150 macros directly, giving much shorter and simpler code.
4152 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4154 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4155 space before "$ac_configure_args" to prevent a 'config.status
4156 --recheck' failure if ac_configure_args doesn't contain a leading
4157 space. This works around a problem with the XEmacs configure.ac,
4158 which uses the (undocumented) ac_configure_args variable
4159 inconsistently with Autoconf.
4161 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4163 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4164 Include <limits.h>, and use its INT_MAX to rewrite the
4165 j loop so that it does not overflow 'int'. Problem reported by
4166 Ralf Wildenhues in
4167 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4168 Play it safe by shifting left by 1 rather than multiplying by 2,
4169 as GCC is less likely to optimize this away when the value
4170 is signed (when it assumes overflow leads to undefined behavior).
4171 Also, don't assume time_t uses two's complement.
4173 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4175 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4176 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4177 dumps core on it. Report by Tim Rice.
4179 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4181 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4182 --disable-option-checking to --help output even when
4183 AC_PRESERVE_HELP_ORDER is not used.
4184 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4185 --with argument, rather than argument with [-.] replaced by
4186 underscores.
4187 * NEWS: Fix typo in previous change; the news was in the
4188 wrong section.
4190 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4192 * NEWS: Warnings are now generated by default for unknown
4193 --enable-* and --with-* options.
4194 * doc/autoconf.texi (Option Checking): Renamed from
4195 (Configure Option Checking). Tighten up the wording a bit.
4196 (External Software, Package Options): Cross-reference to Option
4197 Checking, and use this to shorten our section.
4198 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4199 "$x" to test "x$foo" != x.
4200 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4201 Don't warn if $enable_option_checking is "no".
4202 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4203 ac_unrecognized_opts to the empty string.
4204 Don't echo the unrecognized opts, as this might mishandle
4205 backslashes or leading -.
4206 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4207 usage next to the other --disable-FEATURE options in the
4208 help string.
4210 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4212 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4213 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4214 Print warning for unrecognized --with and --enable options
4215 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4216 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4217 Disable option checking when subdirs are configured.
4218 (AC_OUTPUT): If warnings are enabled, print warning about
4219 unrecognized --with and --enable options at the end of
4220 the configure output (as well as at the beginning).
4221 * doc/autoconf.texi (Option Checking): New node.
4222 Document new option warning functionality.
4224 2006-12-16 Eric Blake <ebb9@byu.net>
4226 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4227 * NEWS: Start news for current version.
4229 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4231 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4232 Define HAVE_GETMNTENT to 1, not to the empty string.
4233 Problem originally reported by Jochen Friedrich in
4234 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4236 This change prompted by a problem report by Andrey Simonenko in
4237 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4238 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4239 object-like macros only, in the traditional portable character
4240 set.
4241 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4242 Warn about attempts to define things that are not identifiers.
4243 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4244 awful hack that AC_DEFINEd macro names containing parentheses.
4246 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4248 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4249 too drastic, even if Texinfo in theory requires it for info mode.
4251 (config.status Invocation): Renamed back from Recreating a
4252 Configuration).
4253 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4254 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4256 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4258 * NEWS: Version 2.61a.
4260 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4261 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4263 * NEWS: Document changes with echo and printf, and the lack
4264 of limits on the total size of multi-line values of substituted
4265 variables, and the AC_FUNC_FSEEKO fix.
4267 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4269 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4270 Writing configure.ac.
4271 (Autoconf Input Layout): Renamed from configure.ac Layout.
4272 (Recreating a Configuration): Renamed from config.status Invocation.

4274 (acconfig Header): Renamed from acconfig.h.
4275 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4276 (Writing Testsuites): Renamed from Writing testsuite.at.
4277 (Autom4te Cache): Renamed from autom4te.cache.
4279 * BUGS: Remove mention of VPATH problem, since it's now documented
4280 not to be a bug in the Autoconf build procedure itself, but rather
4281 a problem with the proprietary `make' programs.
4283 * doc/autoconf.texi (Build Directories): Add a cross reference
4284 to VPATH and Make.
4286 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4287 * doc/standards.texi: Sync from gnulib.
4289 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4290 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4291 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4292 generated automatically.
4294 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4296 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4297 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4298 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4300 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4302 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4303 `CEOF$ac_eof' special marker, the awk script cannot contain a
4304 line matching `^CEOF', so this is not needed any more.
4305 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4306 special marker in the test.
4308 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4310 * tests/tools.at (autom4te preselections): Use `find -newer';
4311 remove one of the sleeps.
4313 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4314 more readable, using ...
4315 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4317 * doc/autoconf.texi (autoheader Invocation): Do not double-
4318 quote the parameter of `AH_BOTTOM' in the example.
4320 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4322 * doc/autoconf.texi (Configuration Headers): Remove the
4323 example with multiple input files.
4324 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4325 multiple input files.
4327 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4329 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4330 creating the awk substitution script, handle one input line at a
4331 time, so that the maximum length of a substituted (multi-line)
4332 value is not limited by the size of the sed pattern space.
4333 The trade-off is a slightly repetitive sed script.
4334 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4335 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4336 * tests/torture.at (Substitute a 2000-byte string): Increase the
4337 test with several long lines, they should not be caught by sed
4338 limits any more.
4340 * tests/tools.at (autom4te preselections): New test, to flag
4341 entries missing from autom4te.cfg.
4342 Report by David Byron <dbyron@hheld.com>.
4344 * tests/torture.at (Substitute a 2000-byte string): Actually use
4345 AC_PROG_AWK, so the last change works as intended.
4346 (Substitute and define special characters): Likewise.
4347 (Substitute a newline): Likewise.
4349 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4350 instead of `awk' consistently.
4351 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4352 * tests/torture.at (Torturing config.status): Test both the
4353 result of AC_PROG_AWK and plain awk.
4354 (Substitute a 2000-byte string): Likewise.
4355 (Substitute and define special characters): Likewise.
4356 (Substitute a newline): Likewise.
4358 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4360 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4361 can be assigned to a function pointer. Problem reported by
4362 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4363 part of a patch by Ralf Wildenhues in that same bug report.
4365 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4367 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4368 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4370 2006-12-01 Eric Blake <ebb9@byu.net>
4372 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4373 cross-compiling from cygwin to mingw.
4374 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4375 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4376 to lib/autoconf/c.m4.
4378 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4380 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4381 string for more reliable failure. Wrap the entire test that
4382 causes the broken Solaris printf to dump core, in a subshell,
4383 so the segmentation fault message is reliably suppressed.
4384 Fix shell expansion errors by using /usr/ucb/echo always;
4385 avoid an error on systems without it by another subshell.
4386 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4387 subshell-$as_echo to `as_echo', for better error message.
4389 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4391 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4392 `BASH_SOURCE' contain a newline, set them to empty, as they may
4393 not be unset.
4395 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4397 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4398 years and is too hard to maintain now. The last straw was
4399 reported by Jerker Baeck in
4400 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4401 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4402 * doc/autoconf.texi (Particular Functions): Move
4403 AC_FUNC_SETVBUF_REVERSED from here...
4404 (Obsolete Macros): ... to here. Say that it does nothing now.
4405 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4406 Turn into (almost) a no-op.
4408 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4409 (AC_C_VOLATILE):
4410 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4411 These macros are obsolescent and new applications shouldn't need them.
4412 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4413 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4414 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4415 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4416 (AC_FUNC_VPRINTF): Likewise.
4417 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4418 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4419 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4421 * doc/autoconf.texi (Setting Output Variables): Mention that
4422 @VAR1@VAR2 has unspecified behavior. Problem reported by
4423 Ralf Wildenhues.
4424 * NEWS: Mention this.
4426 * Makefile.am: Put only a single '#' into the copyright notice,
4427 so that it's also present in the output file. Standardize wording
4428 in makefile copyright notices to match GNU coding standards.
4429 * bin/Makefile.am: Likewise.
4430 * doc/Makefile.am: Likewise.
4431 * lib/Makefile.am: Likewise.
4432 * lib/freeze.mk: Likewise.
4433 * lib/autoconf/Makefile.am: Likewise.
4434 * lib/autoscan/Makefile.am: Likewise.
4435 * lib/autotest/Makefile.am: Likewise.
4436 * lib/m4sugar/Makefile.am: Likewise.
4437 * man/Makefile.am: Likewise.
4438 * tests/Makefile.am: Likewise.
4439 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4440 one-line file.
4442 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4444 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4445 in the sed script that mangles the awk script: delete up to the
4446 first exclamation mark only.
4447 * tests/torture.at (Substitute and define special characters):
4448 Test '!' too.
4450 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4452 Rewrite config files generation: avoid quadratic growth in
4453 the number of substituted variables by using awk instead of sed
4454 for the bulk of the substitutions.
4455 * NEWS: Mention this.
4456 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4457 forbidden in the output (and thus input) file.
4458 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4459 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4460 generate just one large awk script for substitutions,
4461 eliminating much of the earlier complexity, while adding some
4462 new complexity. Only expand the substitution templates at
4463 configure time, for smaller configure script size. If
4464 _AC_SUBST_FILES are used, test 'awk' for working getline support
4465 at config.status time. If absent, interpolate through the
4466 shell. The awk script was written with much help
4467 from Paolo Bonzini and Paul Eggert.
4468 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4469 (_AC_SED_FRAG_NUM): Likewise.
4470 (_AC_SUBST_CMDS): Renamed from...
4471 (_AC_SED_CMDS): ...this.
4472 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4473 * tests/torture.at (Substitute a 2000-byte string): Also
4474 substitute a line with 1000 words, and a variable with several
4475 long lines.
4476 (Substitute and define special characters): Test awk special
4477 characters, and put substitution input strings `@foo@' in the
4478 output, to test that no recursion happens; test several other
4479 combinations from Paolo Bonzini.
4481 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4483 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4484 that replaced echo with AS_ECHO where this wasn't necessary.
4485 Problem reportd by Ralf Wildenhues.
4486 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4487 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4488 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4490 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4492 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4494 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4496 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4497 that traditional Awk lacks 3-arg "split". It has it.
4498 Mention that FS must be a single character, and a few other
4499 99-byte limits of traditional Awk.
4500 Mention that if (i in a) doesn't work with traditional Awk.
4502 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4504 * tests/autotest.at (BSx641-newline in command):
4505 (BS-BS-newline in command, BSx640-newline in command):
4506 (Newline-CODE-BS-newline in command):
4507 (Single-quote-BS-newline in command):
4508 (Single-quote-newline-BS-newline in command):
4509 Use printf '%s\n' instead of echo, for portability to hosts
4510 where echo interprets backslashes. This will break on hosts
4511 that lack printf, but for now let's assume all such hosts
4512 are dead (if not, we should get reports of test failures).
4514 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4516 'echo' has some portability problems, when given a first argument
4517 with a leading '-', or when given any argument containing '\'.
4518 Avoid using 'echo' in these cases.
4519 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4520 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4521 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4522 * lib/autotest/general.m4 (AT_INIT): Likewise.
4523 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4524 argument might be unportable.

4526 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

4543 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4544 * bin/autoconf.as: Redo verbose flag implementation, as the old
4545 scheme wouldn't work with AS_ECHO.
4546 * lib/autotest/general.m4 (AT_INIT): Likewise.
4547 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4548 Don't use ECHO_T, since ECHO_N is now reliable.
4549 * lib/autotest/general.m4 (AT_INIT): Likewise.
4550 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4551 rather than using a here-document to put the script into a file.
4552 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4553 use AS_ECHO.
4554 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4555 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4556 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4557 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4558 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4559 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4560 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4561 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4562 operand, as AS_ECHO requires. Avoid double file name expansion.
4563 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4564 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4565 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4566 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4567 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4568 Double-quote strings that would otherwise contain M4 comments.
4569 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4571 * configure.ac (AC_INIT): Bump to 2.61a.
4572 * NEWS: Likewise.
4574 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4576 Version 2.61.
4578 * configure.ac (AC_INIT): Bump to 2.61.
4579 * NEWS: Likewise.
4581 * tests/autotest.at (Macro with backslash in a test title):
4582 Comment out for now, as this tests neither fails nor passes
4583 reliably. Problem reported by Ralf Wildenhues.
4585 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4587 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4588 in previous change, which caused test failures.
4590 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4592 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4593 code for --enable, --disable, --with, and --without to...
4594 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4595 * doc/autoconf.texi (Package Options):
4596 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4598 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4600 Import these changes from config via gnulib:
4602 2006-11-15 Ben Elliston <bje@gnu.org>
4604 From Josselin Mouette <joss@debian.org>:

4657 first argument may also contain dots.
4659 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4661 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4662 benefit of platforms like Solaris+GCC where it is common to have a
4663 non-working g++ installation.
4665 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4666 and Joel E. Denny <jdenny@ces.clemson.edu>
4667 and Paul Eggert <eggert@cs.ucla.edu>
4669 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4670 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4671 ./micro-suite.
4673 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4675 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4676 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4677 Imported from a similar patch to gnulib by Bruno Haible.
4679 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4681 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4688 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
4689 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
4690 Matthew Woehlke.
4692 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4694 * tests/torture.at (Configuring subdirectories): Do not skip
4695 Automake 1.10 nor future Automake 11.1 (sic).
4697 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4698 and Stepan Kasal <kasal@ucw.cz>
4700 Handle special characters in test case titles correctly.
4701 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4702 properly.
4703 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4704 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4705 argument. Extend to check titles printed by ./micro-suite and
4706 ./micro-suite -l and the title in micro-suite.log.
4707 (Backquote in a test title,
4708 Single-quote in a test title,
4709 Double-quote in a test title): Don't expect failure anymore.
4710 (Backslash in a test title): Put a non-whitespace character after the
4711 backslash so that Bourne shells might actually see it as an escape
4712 sequence.
4713 (Brackets in a test title,
4714 Pound in a test title,
4715 Comma in a test title,
4716 Quoted Macro in a test title,
4717 Macro in a test title,
4718 Macro with single-quote in a test title): New tests.
4719 (Macro with backquote in a test title,
4720 Macro with double-quote in a test title,
4721 Macro with backslash in a test title): New tests expected to fail.
4722 * tests/torture.at (#define header templates): M4-quote this title in
4723 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4724 The visible effect was a stray [] in the testsuite output.
4726 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4728 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4729 `trap ... 0' inside a function, for AIX sh.
4731 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4733 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4734 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4735 5363) simply issues a warning when dividing by zero at compile
4736 time. Problem reported by Elias Pipping.
4738 2006-10-26 Eric Blake <ebb9@byu.net>
4740 * THANKS: Update.
4741 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4742 show effect on macros that expand with commas.
4743 Reported by Joel E. Denny.
4745 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

4751 Jim Meyering.
4753 2006-10-25 Stepan Kasal <kasal@ucw.cz>

4770 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4771 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4772 reported by Nelson H. F. Beebe for Coreutils 6.4.
4774 * tests/tools.at (autoconf --trace: user macros): Remove test
4775 for tracing multiline macros, since m4 1.4.7a uses a different
4776 way to number lines. Problem reported by Ralf Wildenhues.
4778 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4780 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4781 /dev/null since the heuristics for interactive behaviour was
4782 fixed in CVS m4.
4784 * bin/autom4te.in: With --force, always refresh the output
4785 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

4804 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4805 AC_CACHE_CHECK_INT, since it's no longer public.
4806 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4807 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4809 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4838 looking for special shell characters.
4839 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4840 macro defined by AS_VAR_PUSHDEF before passing it as a
4841 parameter.

4852 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4854 (Imported from Automake.)
4855 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4856 which incorrectly sets the mode of an existing destination
4857 directory. In some cases the unpatched install-sh could do the
4858 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4859 system. We hope this is rare in practice, but it's clearly worth
4860 fixing. Problem reported by Alex Unleashed in
4861 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4862 Also, don't bother to check for -m bugs unless we're using -m;
4863 suggested by Stepan Kasal.

4871 is enabled by default with gnu and gnits strictness.
4872 Report from Bruno Haible.
4874 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4876 gnu and gnits modes.
4878 Import this change from Config:
4880 2006-09-20 Ben Elliston <bje@gnu.org>

4883 Import this change from Gnulib:
4885 2006-09-16 Karl Berry <karl@gnu.org>
4886 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4887 to avoid sectioning errors.
4889 Import these changes from Texinfo:
4891 2006-10-04 Karl Berry <karl@gnu.org>
4892 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

4896 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4897 (\code): must use new \...Char values, since now ` is active.

4900 * build-aux/texinfo.tex (\textdegree): New command.
4902 2006-08-12 Karl Berry <karl@gnu.org>

4907 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4909 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4911 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4912 added to the template can get mangled.
4914 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4916 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4917 include the default headers, and redefine obstack_chunk_alloc
4918 and obstack_chunk_free. Fixes false failure with glibc.
4920 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4922 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4923 for backward compatibility with Libtool 1.5.22. Problem reported
4924 by Ralf Wildenhues.
4926 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4928 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4929 AC_PROG_CC.
4930 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
4932 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4934 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4935 the NonStop platform.
4936 * doc/autoconf.texi (Posix Variants): Likewise.
4937 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4939 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4940 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4941 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4942 Use a better substitute, by inspecting the output of "ls"
4943 rather than just using ":".
4944 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4945 rather than AS_EXECUTABLE_P, since we needn't worry about
4946 non-regular files here.
4948 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4949 due to configuration hassles with this. See Tonya Underwood's report
4950 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4959 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4961 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4962 initialization which is not inherited through the environment
4963 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4964 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4966 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4968 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4969 problems with mkdir -p -m.
4971 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4973 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4974 comment about ac_cpp_err; it was incorrect, and anyway
4975 ac_cpp_err is being removed below.
4976 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4977 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4978 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4979 nobody uses it.
4980 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4981 with werror_flag and conftest.err and so forth. This is more
4982 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4983 and anyway the user shouldn't normally want to see this gorp logged.
4984 Problem reported by Ralf Wildenhues.
4985 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4986 empty, not 'no', since the rest of the code uses 'test -z'.
4988 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4990 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4991 Use a single call to AC_DO_TOKENS rather than multiple, for
4992 efficiency.
4993 (_AC_LINK_IFELSE): Test that resulting file is executable.
4994 Problem reported by mwoehlke in
4995 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4997 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4998 than creating a file to use with test -x; this is much faster.
5000 2006-10-02 Bruno Haible <bruno@clisp.org>
5002 * lib/autom4te.in (Automake-preselections): Add
5003 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
5005 2006-09-27 Stepan Kasal <kasal@ucw.cz>
5007 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
5008 standard error, `experr' should be used, not `expout'.
5010 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
5012 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
5013 fseeko testing program twice; just use the earlier result.
5014 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
5015 Set cache var to 'unknown' (not 'no') if leaving the macro unset
5016 still doesn't let the program compile.
5017 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
5018 failed.
5020 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
5021 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
5022 include it, without including anything else.
5023 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
5024 expressions.
5025 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
5027 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5029 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
5030 `error.h', and include it, for a `error_at_line' prototype.
5031 Use a nonempty format string in the link test.
5032 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
5033 for a declaration of wait3.
5035 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
5037 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
5038 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
5039 can apply to constants too, and that it checks for macro defns.
5040 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
5041 and simply cast the identifier to void. This handles structure
5042 values. Problem reported by Ralf Wildenhues.
5043 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
5045 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5047 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,

5100 --error-output, to avoid warnings with M4 2.0.
5102 2006-09-19 Stepan Kasal <kasal@ucw.cz>
5104 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

5117 the path at runtime.
5119 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5121 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

5125 for both changes.
5126 * doc/autoconf.texi (Setting Output Variables): Fix example to

5129 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5131 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
5132 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
5133 for the existence of the directory at configure-time. That's
5134 too late, anyway. Problem reported by Stefan Seefeld.
5136 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
5137 7.1.4 /usr/bin/posix/sh described by Tim Rice in
5138 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
5140 2006-09-11 Stepan Kasal <kasal@ucw.cz>
5142 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
5143 works with GNU M4 1.4.3 again; make the normalized form
5144 match the current m4 message; fix the description.

5147 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
5149 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
5150 to catch glibc bug 2821
5151 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
5153 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
5154 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
5155 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
5156 assume C89.
5158 2006-09-08 Stepan Kasal <kasal@ucw.cz>

5178 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over

5180 accept files with extension `.f'. For consistency, also prefer
5181 xlf over f77.
5182 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
5183 from last patch.

5204 except the first two arguments are reversed.
5205 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
5206 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
5207 caches nor outputs a diagnostic. Suggested by Bruno Haible.
5208 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
5209 equivalent to the old AC_COMPUTE_INT.
5210 (AC_COMPUTE_INT): No longer caches or reports. New signature.

5215 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
5217 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
5218 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
5219 programs should use their Gnulib counterparts.
5220 * doc/autoconf.texi (Particular Functions): Likewise.
5221 (Macro Names, testsuite Invocation): Replace uses of these
5222 obsolete macros with uses of non-obsolete macros.

5246 simplify the code.
5248 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
5250 Fix Lex library problem reported to us by Julio Garvia.
5251 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
5252 for the default, which the user can override.
5253 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
5254 deal with LEXLIB.
5255 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
5256 didn't work if some values were cached but not others. Test for
5257 broken lex libraries like native ia64-hp-hpux11.22; see
5258 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
5259 work around the problem by preferring an empty LEXLIB to -lfl or
5260 -ll. Let the user set LEXLIB='' to indicate no library needed.
5262 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
5263 * README: Likewise.
5264 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

5389 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
5390 * doc/autoconf.texi (Header Templates, Default Includes):

5405 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
5406 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
5407 this.

5411 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
5412 problems with arg script text that doesn't end in newline, and

5427 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
5428 --help' should mention that `--version' outputs configuration
5429 settings. Report by Bruno Haible.
5431 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
5433 Fix test suite failures reported by Pierre in

5449 less skeptical about "volatile", after discussion with
5450 Bruno Haible on bug-gnulib.
5451 (Limitations of Usual Tools): Warn about sed stripping
5452 leading white space from text. From Bruno Haible.
5454 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5456 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5457 compiler complains about it, even if things works after the
5458 complaint. Problem reported by Peter O'Gorman.
5460 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5461 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5462 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5464 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5466 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

5474 to match M4 1.4.5.
5476 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5478 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5479 under AC_C_VOLATILE.
5480 (Volatile Objects): Be a little less skeptical about what
5481 "volatile" means. Derived from thoughts by Ben Pfaff in
5482 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5484 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5486 * doc/autoconf.texi: Fix some typos.
5488 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5490 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5491 more globally, since the 2006-06-30 patch didn't suffice. Problem
5492 reported by Keith Marshall. Also, don't bother with builddir2,
5493 since it shouldn't be needed any more.
5495 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5497 * doc/autoconf.texi (Generic compiler characteristics):
5498 Document AC_COMPUTE_INT. Fix wrong statements on Default

5512 * NEWS: Document previous change.
5514 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5516 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5517 Require that long long int be at least 64 bits wide. C99 requires
5518 this and enough programs depend on it so we should check for it.
5519 Bruno Haible reports in
5520 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5521 that long long int is 32 bits wide with some nonstandard compilers.
5522 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5524 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5526 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5527 to a nonexistent file, so that we don't have to worry about
5528 a local site configuration that doesn't use /usr/local.
5529 Problem reported by Keith Marshall in
5530 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5532 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5534 * doc/autoconf.texi: Be more consistent about using @acronym with
5535 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5536 quite right (it talked about "OSF/Tru64", even though the
5537 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5538 and it even mentioned "OSF 4"!) and at this point there's little
5539 reason to talk about OSF any more, since it died in 1994.
5540 (Specific Compiler Characteristics): Simplify example of
5541 negative-size array.
5542 (File Descriptors): Reorder to make the text flow better.
5543 Remove joke about "appreciate the various levels"; I didn't get it.
5544 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5545 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5546 (File Descriptors, Limitations of Usual Tools):
5547 Tone down the advice against renaming or removing open files.
5548 (Limitations of Usual Tools): Add a new section, on 'rm'.
5550 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5552 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5553 -lXt in LIBS, idea from Karsten Hopp; this was due since
5554 this change:
5556 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5557 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5558 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5559 (which belong to Xt, not X itself). See Debian bug 327655.
5561 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5563 * configure.ac (AC_INIT): Bump to 2.60a.

5577 quadrigraph correctly in traces.
5579 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5580 Fix typos.
5582 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5583 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5584 not defined.
5585 * doc/autoconf.texi (Changed Directory Variables): New node,
5586 to document the whole `datarootdir' business a bit better.
5587 * NEWS: Update.
5588 * tests/torture.at (datarootdir workaround): Extend test.
5589 Prompted by report by Alexandre Julliard.
5591 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5593 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

5595 fix reported by Larry Jones.
5597 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5599 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5600 about literal '${datarootdir}' if a definition is found in the
5601 output file.
5603 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5605 * NEWS: Use "M4" rather than "m4" when appropriate.
5606 Problem reported by Eric Blake.
5607 * doc/autoconf.texi: Likewise.
5608 Use @acronym around BSD, GCC, and GNU when appropriate.
5609 (Why GNU M4): Renamed from "Why GNU m4".
5610 (Redefined M4 Macros): Mention that Posix
5611 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5612 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5613 to int.
5615 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5617 * bin/autom4te.in (handle_output): Do not forbid the empty
5618 pattern.
5619 * tests/tools.at (autoconf: the empty token): New test.
5621 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5623 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5624 calls, so that we do not care whether they are LIFO or FIFO;
5625 in the m4_wrap, do not check which diversion is the topmost
5626 one, just check that the stack is balanced at the end.
5627 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5628 base diversion forever--pop the previous diversion before
5629 opening the new one; consequently, remove the m4_wrap call.
5630 * lib/autotest/general.m4 (AT_INIT): Likewise.
5631 * tests/m4sugar.at: Do not use
5632 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5634 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5635 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5637 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5638 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5639 Rework example of m4wrap token-pasting trouble so that it doesn't
5640 care whether it's LIFO or FIFO.
5641 Fix some "contrary to"s that are awkward in English.
5643 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5645 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5646 to `yes' instead of `int$1_t' if the type is found, for more
5647 consistent configure output (where $1 is the number of bits).
5648 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5649 Suggested by Bruno Haible.
5651 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5652 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5653 with system headers. Report by Bruno Haible.
5655 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5657 * config/config.guess, config/config.sub: Sync from upstream.
5659 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5660 in order to avoid picking up an older installed frozen m4sh.m4f.
5661 Besides an outdated shell startup, this could have been created
5662 by an earlier M4 version with incompatible frozen file format.
5664 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5666 * README: Recommend m4 1.4.4 instead of 1.4.3..
5667 * doc/autoconf.texi: Likewise.
5668 (Special Chars in Names): Say that $(.FOO) is portable, as
5669 suggested by Stepan Kasal.
5670 (Installation Directory Variables, Build Directories):
5671 (Automatic Remaking, Subdirectories, Fortran Compiler):
5672 (Making testsuite Scripts, Defining Directories):
5673 Quote variable usages better.
5674 (Making testsuite Scripts): Add clean-local rule to makefile
5675 snippet, by Eric Blake.
5676 (Installation Directory Variables): Fix table item font.
5677 Reword slightly to clarify. Generalize advice about
5678 not using special characters to include all file-related
5679 vars, not just VPATH.
5680 (Special Chars in Variables): Warn about special characters in
5681 $(srcdir) too.
5682 (Assignments): Clarify default-value example as suggested by
5683 Ralf Wildenhues in
5684 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5685 (Special Shell Variables): Note leading ./ or ../, as suggested
5686 by Eric Blake.
5687 (Limitations of Builtins): Under cd, warn about CDPATH.
5688 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5689 Ralf Wildenhues.
5691 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5693 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5694 `@var', for texi2html.
5695 (Systemology): Some more word wrapping, for DVI output.
5696 (autom4te Invocation): The short option for `--melt' is `-M',
5697 not `-m'.
5699 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5701 * doc/autoconf.texi: More formatting and English tweaks,
5702 many suggested by Ralf Wildenhues.
5703 Reword to avoid "@code{...}'s" and the like, since it's ugly
5704 with Emacs info mode. discontents -> woes.
5705 Put a few "will"s back. time stamp -> timestamp.
5706 side-effect -> side effect.
5708 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5710 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5711 Warn about $@ not persisting. Problem reported by Julien Danjou in
5712 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5713 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5714 Mention other special chars, too.
5716 2006-06-14 Eric Blake <ebb9@byu.net>
5718 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5720 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5722 * doc/autoconf.texi: Some systematic minor improvements, as
5723 follows. Use "makefile" when talking about makefiles
5724 generally (which might be named "makefile" or "Makefile" or even
5725 "foo.mk"), "Makefile" when talking about a specific makefile
5726 called "Makefile". This unclutters the text from weird quotes
5727 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5728 values" rather than "@var{foo}s" and similar constructs containing
5729 "}s". Use "Make rules" rather than "Makefile rules". Minor
5730 English-language improvements. Change the prefix "sub-" to "sub"
5731 and "re-" to "re".
5732 Put blank lines around examples more consistently.
5733 Avoid "rather" and "very" as intensifiers.
5734 Avoid "will" as an auxiliary.
5735 (Limitations of Make): Split this node into....
5736 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5737 (Leading _ in Macro Names, Backslash-Newline-Newline):
5738 (Backslash-Newline Comments, Long Lines in Makefiles):
5739 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5740 (obj/ and Make, make -k Status, VPATH and Make):
5741 (VPATH and Double-colon, $< in Explicit Rules):
5742 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5743 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5744 New nodes, resulting from splitup of Limitations of Make.
5745 All cross-references changed. Raise the top node from
5746 a section to a chapter, and all subnodes accordingly.
5747 Redo the introductory wording to match the new organization.
5748 (Installation Directory Variables): Use an example that is
5749 closer to what Autoconf actually does. Mention that VPATH's
5750 value should not contain metacharacters or white space.
5751 (Fortran Compiler): Fix a VPATH bug in an example.
5752 (Leading _ in Macro Names): Mention that this problem is no longer
5753 of practical concern.
5754 (VPATH and Make): Reword the advice to make it clearer
5755 that Autoconf and Automake support VPATH in non-GNU make, but
5756 many packages have bugs in this area.
5757 ($< in Explicit Rules): Refer to Build Directories rather
5758 than using a (non-VPATH-safe) example.
5759 (Automatic Rule Rewriting): Mention the sort of disaster that
5760 can ensue with Solaris-style rule rewriting with VPATH.
5762 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5764 * doc/install.texi (Compilers and Options): Weaken the
5765 suggestion to use GNU make for VPATH builds.
5767 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5768 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5770 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5771 in regular expression.
5773 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5775 * doc/autoconf.texi (Installation Directory Variables):
5776 Drop extra @samp from `@table @samp' item.
5777 (Limitations of Usual Tools): Comment fix.
5778 Do not nest @samp just to point to other table items.
5779 (Writing testsuite.at) <AT_CHECK>: The second argument to
5780 `@dvar' is already @samp'ed.
5781 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5782 do not use @var in the second argument.
5784 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5786 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5787 $as_shell.exe too. Problem reported by Andreas Buening in
5788 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5790 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5792 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5793 `unused variable' compiler warning, for `-Wall -Werror'.
5794 Reported by Jaap Haitsma in
5795 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5797 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5799 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5800 case the compiler dumps core. Problem reported for
5801 OpenServer 5.0.7 by Tim Rice in
5802 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5803 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5804 Likewise.
5806 2006-06-06 Tim Rice <tim@multitalents.net>.
5808 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5809 "ERROR" only shows up in "make check" output if there is an
5810 error.
5812 2006-06-06 Eric Blake <ebb9@byu.net>
5814 * tests/tools.at (automatically allowed tokens): Fix typo.
5816 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5818 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5820 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5821 typically overflows on x86 CPUs, even though the C standard
5822 requires otherwise.
5824 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5826 * configure.ac (AC_INIT): Bump to 2.59e.
5827 * NEWS: Update.
5829 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5831 Version 2.59d.
5833 * config/texinfo.tex: Sync from upstream.
5835 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5836 seen, invoke libtoolize with `--ltdl' argument.
5837 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5838 * NEWS: Update.
5839 Suggested by Eric Blake.
5841 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5843 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5844 reported by Ralf Wildenhues.
5845 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5847 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5849 * THANKS: Update.
5851 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5853 * doc/autoconf.texi: Modernize some of the references to Solaris.
5855 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5857 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5858 message issued by AC_REQUIRE.
5859 * tests/m4sugar.at: Check m4_require's error message.
5860 * tests/base.at: Check AC_REQUIRE's error message.
5861 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5862 to...
5863 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5864 AT_CHECK_M4.
5865 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5866 `expout' as the last parameter.
5867 * tests/tools.at: Adapt to the above change.
5869 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5871 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5872 information about race-free implementations of mkdir.
5874 2006-06-04 Eric Blake <ebb9@byu.net>
5876 * bin/autoreconf.in (help): Document M4 environment variable.
5877 * bin/autoconf.as (Usage): Likewise.
5878 * bin/autom4te.in (help): Likewise.
5879 * doc/autoconf.texi (autom4te Invocation): Likewise.
5881 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5883 * NEWS: GNU make now recommended for VPATH builds.
5884 Mention that some macros are now documented to be obsolescent.
5885 * doc/autoconf.texi:
5886 Prefer "current" to "modern" to describe
5887 currently-used (albeit perhaps old-fashioned) hosts.
5888 Mention which ancient features no longer need to be worried about.
5889 setgid -> set-group-ID
5890 setuid -> set-user-ID (these are the Posix terms)
5891 Fix some misuses of "only".
5892 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5893 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5894 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5895 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5896 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5897 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5898 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5899 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5900 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5901 Mention that these macros are obsolescent.
5902 (Installation Directory Variables): shall -> should
5903 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5904 Mention that it's now safe to use 3 and 4.
5905 (Limitations of Usual Tools): cp -r is now specified by Posix.
5906 Omit longwinded and obsolescent discussion of cp -f.
5907 Modernize discussion of expr, ls.
5908 (Limitations of Make): Modernize discussion of VPATH builds.
5909 Mention $? as a workaround in some cases.
5910 * doc/install.texi (Basic Installation):
5911 Mention "./configure; make; make install" first. Be more
5912 specific about why this file is generic. Remove unnecessary
5913 parens. Remove misleading "only". Remove obsolete advice
5914 about csh. Don't say "configure" takes awhile; say it
5915 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5916 and CC=c99 rather than CC=c89, as these are blessed by current
5917 Posix. Recommend GNU make if doing a VPATH build.
5919 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5921 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5922 examples involving shell prompts.
5924 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5925 and Paul Eggert <eggert@cs.ucla.edu>
5927 * doc/autoconf.texi (Here-Documents): Add details about the
5928 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5929 use "here-documents" instead of "here documents".
5931 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5933 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5935 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5937 * doc/autoconf.texi (File System Conventions): Warn about ":"
5938 anywhere in directory names.
5940 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5942 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5943 about quoting the case statement, just in case.
5944 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5945 was fixed in ksh93g; reported by Ralf Wildenhues.
5947 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5949 * doc/autoconf.texi (System Services): Do not document
5950 overriding EXEEXT via ac_cv_exeext=ext.
5951 (Particular Programs) <AC_PROG_MKDIR_P>:
5952 Document that ${MKDIR_P} understands --.
5953 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5954 comment.
5956 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5958 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5959 argument with leading hyphen. Problem reported by Paul Eggert.
5961 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5963 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5964 about quoting ac_try: quote all of it, if any of it seems suspicious.
5965 This means we don't have to worry about ${ or sed any more.
5966 Also, double-quote the case statement, to work around misuses via
5967 underquoting as reported by Ralf Wildenhues in
5968 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5969 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5970 undocumented and dangerous macro.
5971 Problem reported by Ralf Wildenhues in
5972 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5974 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5976 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5977 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5978 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5980 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5982 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5983 since evidently some packages rely on the old, broken behavior.
5984 Problem reported by Ralf Wildenhues in
5985 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5986 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5987 pre-2006-05-26 definitions, but leave in the comments that
5988 these macros are dangerous and should not be used.
5989 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5990 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5991 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5992 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5993 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5995 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5997 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5998 the use of 'tr', since this is our only use of 'tr'.
6000 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6001 and Paul Eggert <eggert@cs.ucla.edu>
6003 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
6004 Don't assume 'grep' works on long lines, since AIX grep doesn't.
6006 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6008 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
6009 the output file in the `${datarootdir}' test.
6011 2005-05-28 Stepan Kasal <kasal@ucw.cz>
6012 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6014 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
6015 mention of `datarootdir' in the input file(s), but literal
6016 `${datarootdir}' in the output file, and we haven't warned yet,
6017 then warn as well: the user may have (erroneously) used
6018 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
6019 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
6020 * tests/torture.at (datarootdir workaround): Extend this test.
6021 * NEWS: Update.
6023 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6024 and Paul Eggert <eggert@cs.ucla.edu>
6026 * doc/autoconf.texi (autoheader Invocation): The first argument to
6027 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
6028 alternatives and clear up the language a bit.
6030 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
6032 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
6033 ac_config_guess, ac_config_sub, ac_configure.
6034 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6035 Fix typo that prevented an unnecessary space from being removed.
6036 Problems reported by Ralf Wildenhues in:
6037 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
6039 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
6041 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
6042 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
6043 Don't use the term "thread-safe" to talk about mkdir race
6044 conditions, since the problem is more a process than a thread
6045 issue. Problem reported by Stepan Kasal in:
6046 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
6047 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
6048 the test for 'install' more closely. Look at MKDIR_P first.
6049 Look in the PATH, and at /opt/sfw/bin.
6050 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
6051 Don't bother to try mkdir -p, since we already check mkdir --version;
6052 just look at the version number. (There's no easy way to check
6053 for race-free implementations.)
6054 * tests/tools.at (autoconf: subdirectories): Adjust to above
6055 changes, since MKDIR_P now might end in "/mkdir -p".
6057 * doc/autoconf.texi (autoheader Invocation): Mention that the
6058 first arg of AC_DEFINE_UNQUOTED must be a literal.
6059 Problem reported by Ben Pfaff in
6060 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
6062 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
6063 * doc/autoconf.texi (Special Chars in Variables): New section.
6064 (Preset Output Variables): Warn about special chars in CPPFLAGS.
6065 (Installation Directory Variables): Quote $(datadir) better.
6066 (Limitations of Builtins): Describe some of eval's trickiness.
6068 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
6069 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
6070 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
6071 in front of every arg, not just trailing args. Quote apostrophes.
6072 (_AC_EVAL_ECHO): New macro.
6073 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
6074 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
6075 removed.
6076 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
6077 exposed by quoting of eval argument. Put the command on line line
6078 so it logs better.
6079 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
6080 (_AC_PATH_X, AC_PATH_X): Quote more safely.
6081 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
6082 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
6083 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
6084 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
6085 Use eval more safely.
6086 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
6087 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
6088 to be replaced.
6089 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
6090 lines, exposed by quoting of eval argument.
6092 2006-05-26 Stepan Kasal <kasal@ucw.cz>
6093 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6095 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
6096 initialization of `ac_cv_exeext', do not override it if it was
6097 already set, unless it was set to `no', for compatibility with
6098 Autoconf-2.13, and comment this.
6099 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
6100 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
6101 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
6102 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
6103 Document that this test may be overridden by setting
6104 `ac_cv_exeext'.
6106 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6108 Revert these two patches:
6110 2006-04-06 Eric Blake <ebb9@byu.net>
6111 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6112 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6113 2006-04-01.
6115 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6116 Clean up _AC_COMPILER_EXEEXT* macros.
6117 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6118 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6119 ac_file to the name of the default output file and call
6120 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6121 initial `rm' of the candidate files...
6122 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6123 the same list in subsequent `rm' calls, and for the temporary
6124 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6125 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6126 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6127 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6128 no longer needed) by libtool. Make it a cache check.
6129 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6130 copied here by mistake.
6131 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6132 _AC_COMPILER_EXEEXT.
6133 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6134 _AC_COMPILER_OBJEXT directly.
6135 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6137 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6139 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6140 Fix description of how the buggy `sed' works.
6142 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6144 Sync from Automake:
6146 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6147 ENOLCK. Only mention `make -j' when applicable. Only raise
6148 fatal errors when `make -j' is involved. Improve error message.
6150 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6152 * doc/autoconf.texi (Here-Documents): We now know more about
6153 the variable expansion in here documents bug.
6154 Thanks to Tim Rice and Stepan Kasal.
6156 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6157 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6159 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6161 * tests/autotest.at (Multiline command from M4 expansion):
6162 No failure to be expected if the shell quotes newlines in
6163 commands in the `set -x' output. Report by Tim Rice.
6164 * THANKS: Update.
6166 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6168 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6169 expansion in the here-documents used by config.status, as that
6170 runs afoul of the Korn shell version M-12/28/93d bug described in
6171 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6172 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6173 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6175 2006-05-23 Jim Meyering <jim@meyering.net>
6177 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6178 Fix typo introduced with 2006-04-02 change. It reversed the sense
6179 of the test.
6181 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6183 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6184 ac_dB slightly, to save bytes in the script.
6185 Max out at 50 lines, rather than 96; this is more likely
6186 (though not guaranteed) to avoid obscure 'sed' failures.
6188 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6190 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6191 `tr -d -' as bad option argument. Work around this by deleting
6192 an unrelated character.
6193 Report by Tim Rice <tim@multitalents.net>.
6195 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6196 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6197 Stepan Kasal <kasal@ucw.cz>
6199 * doc/autoconf.texi (Particular Programs): Do not promise that
6200 we always prefer the GNU version of the program, and that we
6201 search according to PATH; both rules can have exceptions.
6202 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6203 AC_PROG_SED. Move descriptions of limitations
6204 to the Limitations of Usual Tools section.
6205 (Limitations of Usual Tools) <sed>: Mention script length
6206 limitations with Solaris /usr/ucb/sed.
6207 <grep>: Fix wording for empty alternative. Mention that -c and
6208 -l should not be combined, and that -E and -F should not be
6209 combined.
6211 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6212 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6214 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6215 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6217 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6219 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6220 AC_DEFINE is now passed to m4_pattern_allow.
6221 * NEWS: Mention that; likewise for AC_SUBST.
6222 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6223 the parameter to m4_pattern_allow.
6224 * tests/tools.at: Add a check for that.
6226 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6228 * lib/autoconf/status.m4: Fix typos.
6230 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6232 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6233 only the files that this macro generates.
6235 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6237 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6238 the HP-UX sed limitation of 99 commands, labels do not count.
6239 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6240 in the comment.
6241 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6243 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6245 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6246 Import the following fix from coreutils:
6248 2006-01-13 Jim Meyering <jim@meyering.net>
6250 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6251 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6252 not double-quote uses of that variable, to accommodate the rare
6253 case in which getmntent is available in none of the libraries
6254 checked. This happens at least on FreeBSD 5.0.
6256 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6258 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6259 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6260 some other programs unwisely rely on these undocumented vars.
6261 But put in warning comments about them.
6262 Problem reported by Ralf Wildenhues in
6263 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6264 * NEWS: Document that these variables are intended to go away.
6266 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6268 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6269 and set the language to C++ (analogous to the equivalent Fortran
6270 tests).
6272 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6273 * doc/autoconf.texi (C++ Compiler): Document it.
6274 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6275 * NEWS: Update.
6277 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6279 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6280 that caused config.status to generate 100-command sed scripts; the
6281 portable limit is 99.
6283 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6285 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6286 variable `ac_d' instead of `d' to avoid infringing namespace.
6287 Report by Ralf Menzel.
6289 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6291 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6292 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6293 * tests/tools.at (autoconf: subdirectories): New test, taken from
6294 the corresponding problem report by Ralf Wildenhues in:
6295 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6297 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6298 Quote some uses of shell variables if they might suffer unexpected
6299 globbing. This doesn't fix all instances of quoting problems that
6300 I found, just the easy ones that look safe.
6301 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6302 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6303 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6304 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6305 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6306 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6307 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6308 Likewise.
6309 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6310 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6312 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6314 * bin/autoreconf.in ($help): Reword according to the manual.
6315 Suggested by Olly Betts.
6317 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6318 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6320 * bin/autoreconf.in: Pass the directory argument to
6321 `require_configure_ac'. Fix comment.
6322 * tests/torture.at (Configuring subdirectories): Expose this.
6323 Reported by Olly Betts.
6325 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6327 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6328 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6329 Automake as follows:
6331 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6332 `$configure_in' instead of `configure.in', to preserve
6333 directory component.
6335 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6337 * config/config.guess, config/config.sub, config/texinfo.tex,
6338 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6340 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6342 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6343 test for C99 conformance; (bool) 0.5 is an integer constant
6344 expression, but (bool) -0.5 is not. Problem reported by Fedor
6345 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6347 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6349 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6350 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6351 Warn about obsolete install-sh files. Remove stray sentence
6352 fragment and fix cross reference.
6353 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6354 install -d; this undoes the 2006-05-10 change.
6355 (MKDIR_P): Mark with AN_MAKEVAR.
6356 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6357 that we don't require $INSTALL to be thread-safe. Move comments
6358 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6359 of AC_PROG_INSTALL. Output a message saying that we're checking
6360 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6361 MKDIR_P instead of AC_SUBST.
6362 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6363 Special magic for MKDIR_P, too.
6364 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6365 a dnl.
6366 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6368 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6370 Sync from Automake, as follows:
6372 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6373 * config/install-sh: Initialize IFS, so field splitting isn't
6374 turned off later.
6375 * config/mkinstalldirs: Likewise.
6376 * config/missing: Remove superfluous quotes. Replace all uses of
6377 `[' by `test', for consistency, and for..
6378 * config/missing (sed_minuso, sed_output): New variables.
6379 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6380 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6381 Fixes `missing' to detect `--output' for help2man. Fixes
6382 PR automake/483. Report by Dennis J. Linse.
6383 (autom4te): Document in `missing --help'.
6385 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6387 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6388 * config/install-sh: Don't use 'path' to talk about file names,
6389 as per GNU coding standards. Close a race condition reported by Ralf
6390 Wildenhues and Stepan Kasal. There is still a race condition
6391 on hosts that predate Posix 1003.1-1992, but we can't help this.
6392 Don't mishandle weird characters like space on pre-Posix hosts.
6393 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6394 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6395 AC_PROG_MKDIR_P from AS_MKDIR_P.
6396 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6397 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6398 earlier editions are not (including Automake 1.8.3).
6399 Do not suggest mkinstalldirs for thread-safety.
6400 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6401 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6402 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6403 presence of special characters and race conditions.
6404 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6405 in Autoconf's name space.
6407 2006-05-10 Bruno Haible <bruno@clisp.org>
6408 and Paul Eggert <eggert@cs.ucla.edu>
6410 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6411 from Automake with minor changes.
6412 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6414 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6416 * config/install-sh: Update to Automake CVS version, as follows:
6417 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6418 * lib/install-sh: Simplify the expr implementation of dirname.
6419 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6420 * lib/install-sh: Handle --, and diagnose unknown options.
6422 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6424 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6425 `./autom4te' to create `./testsuite', since the `all' target
6426 will ensure its presence, but `installcheck' should not create
6427 the uninstalled wrappers.
6429 * tests/torture.at (Unusual Automake input files): Skip if we
6430 detect automake < 1.8.
6432 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6434 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6435 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6436 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6437 * NEWS: Update.
6439 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6441 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6442 munge (multiple) white space and other oddities.
6443 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6444 single quotes in variable assignment.
6445 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6446 and similar failures by adding multiple spaces, tabs, and other
6447 special characters.
6448 Report and different test suggested by Francesco Romani
6449 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6451 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6452 single quotes, we only need to search for single quotes; this
6453 both simplifies the search pattern, and makes us less
6454 susceptible to `echo' variations for arguments not containing
6455 single quotes.
6456 (_AC_ARG_VAR_VALIDATE): Likewise.
6458 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6460 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6461 `$*' and IFS concatenation issue with traditional shells and
6462 bash-2.04. Report by Seanster@Seanster.com.
6464 2006-05-03 Bruno Haible <bruno@clisp.org>
6466 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6467 precisely which Mac OS X versions have the od problem.
6469 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6471 * doc/autoconf.texi: Use @option systematically.
6473 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6474 and Bruno Haible <bruno@clisp.org>
6476 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6477 about 'od'.
6478 (Integer Overflow): Mention the special case of integer division
6479 overflow.
6481 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6483 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6484 traditional shells like the Solaris one that do not use the
6485 first IFS character for assembling `$*'.
6486 Prompted by a related report from autoconf_bug@nro.ca.
6488 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6489 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6491 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6492 Mention more problems with the -e option.
6494 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6496 * NEWS: Typo.
6497 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6499 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6500 in URLs to improve DVI formatted output (requires texinfo 4.6).
6501 (System Services, Systemology, Shellology): Likewise.
6502 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6503 output.
6505 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6506 continuous text.
6507 (Runtime): Fix macro argument names to match description:
6508 `action-if-found' -> `action-if-true' and similarly.
6509 (Obsolete Macros): Likewise.

6511 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6512 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6514 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6516 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6518 * ChangeLog: Typo.
6519 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6520 DVI output.
6522 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6524 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
6525 /bin/sh set unsorted output.
6526 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
6527 * tests/local.at: Likewise.
6529 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
6531 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
6532 (Integer Overflow, Null Pointers, Buffer Overruns):
6533 (Floating Point Portability, Exiting Portably): New sections.
6534 (Writing Test Programs): Fix some langauge. Recommend exiting
6535 with status 1, not merely nonzero. Clarify exit declaration.
6536 (Run Time): Move C exit status stuff to new Exiting Portably section.
6537 (Systemology): Mention Posix and levenez. Update v7 reference.
6538 (Portable Shell): Mention the Posix shell.
6540 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6542 * bin/autoconf.as (me): Replace by as_me.
6544 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6546 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6547 since as_me isn't set yet.
6549 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6551 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6552 a few minor bugs in this area.
6554 * doc/autoconf.texi (Programming in M4sh): Comment out the
6555 documentation of AS_BASENAME, for now.
6556 (Shell Substitutions): Do not use AS_DIRNAME in an example.
6557 (Limitations of Builtins) <basename>: Do not refer to
6558 AS_BASENAME.
6559 * bin/autoconf.as (me): Don't use AS_BASENAME.
6560 (dir): Remove the unused variable.
6561 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6562 AS_DETECT_REQUIRED. All uses changed.
6563 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6564 All uses changed.
6565 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6566 (AS_BASENAME): Use "basename --" to protect against leading "-".
6567 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
6568 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6569 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".

6572 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6573 (AS_DIRNAME): Use "dirname --".
6575 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6577 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6578 of "run time" and "run-time" changed to "runtime", for consistency.
6579 * lib/autoconf/fortran.m4: Likewise (in comment).
6580 * lib/autoconf/functions.m4: Likewise.
6581 * lib/autoconf/general.m4: Likewise.
6582 * lib/autoconf/headers.m4: Likewise.
6584 * doc/autoconf.texi (Run Time): Document the exit status situation
6585 with more accuracy and detail.
6587 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6589 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6590 Archive is not officially `GNU' any more. Update URL.
6591 (Defining Directories): Likewise
6592 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6594 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6596 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6597 newline from the `trap' code to finish `config.log'; the NetBSD
6598 /bin/sh resets the exit status after an empty command, as
6599 documented in doc/autoconf.texi.
6600 Reported by Dalibor Topic <robilad@kaffe.org>.
6602 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6604 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6605 Suggested by Bruno Haible.
6607 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6609 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6610 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6611 Instead, just list the shells that we know work.
6612 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6613 changed. Be more cautious about the _cv_ variable.
6614 * tests/tools.at (Syntax of the shell scripts): Check the
6615 _cv_ variable once, at first, to avoid an internal autoconf error
6616 when sh -n does not work.
6618 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6620 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6622 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6624 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6625 use ">&-" since we're only 99.999% sure that this is portable,
6626 and since the MinGW bug is fixed in a different way.
6627 * lib/autotest/general.m4 (AT_INIT): Likewise.
6629 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6631 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6632 before opening config.log, to avoid hitting a bug on MinGW.
6634 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6636 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6637 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6638 This works around a MinGW bug reported by Eric Paire.
6639 Make sure that all writes to the log file append to it,
6640 rather than possibly losing data.
6641 * lib/autotest/general.m4 (AT_INIT): Likewise.
6643 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6645 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6646 description.
6648 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6650 * NEWS: Update.
6652 * configure.ac (AC_INIT): Bump to 2.59d.
6654 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6656 Version 2.59c.
6658 * Makefile.maint (news-date-check): Do not require a leading `*'
6659 before the release date in NEWS.
6661 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6662 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6664 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6665 the instantiated file do not contain the string 'datarootdir'
6666 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6667 @mandir@, replace the reference '${datarootdir}' by the value.
6668 * tests/torture.at (datarootdir workaround): New test.
6669 * NEWS: Advertise this temporary fixup.
6670 Based on a patch by Bruno Haible, reported and analyzed by
6671 Paul Eggert and Noah Misch.
6673 2006-04-12 Eric Blake <ebb9@byu.net>
6675 * tests/autotest.at (Debugging a failed test): Fix comment.
6677 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6679 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6680 all the changes since 2006-04-07.
6682 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6684 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6685 succeeded, but `ln -s file dir' failed, take care to remove the
6686 leftover target before the next test, to prevent its spurious
6687 failure; also make sure `ln file dir' works before selecting it.
6688 Thanks to Keith Marshall for pointing this out.
6689 * THANKS: Update.
6691 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6692 assignments in `at_debug_args', so that we put them correctly
6693 in the `run' script.
6694 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6695 Reported by Eric Blake.
6697 2006-04-11 Eric Blake <ebb9@byu.net>
6699 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6700 top-level tests after micro-suite has been run. Used in...
6701 (Debugging a successful test, Debugging script and environment),
6702 (Debugging a failed test): ...these new tests. The first of these
6703 is fixed by...
6704 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6705 macro, split out from...
6706 (AT_INIT): ...here, so that using -d also generates a run script.
6707 Document that -d inhibits top-level logging.
6708 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6709 inhibits top-level logging; debug scripts are created.
6711 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6712 check.
6713 * tests/autotest.at (Empty test, Empty check): New test to check it.
6715 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6716 from gcc.
6718 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6720 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6721 the files if a problem appears. Make the empty *.at files
6722 read-only, too. Proposed by Ralf Wildenhues.
6724 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6726 * config/Makefile.am: Add comment to force updated Makefile.in.
6728 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6729 space only patch to this file, this patch causes the Makefile.in
6730 files that include freeze.mk to be updated, and thus have a
6731 newer time stamp again, which in turn makes a pristine CVS
6732 checkout have correct time stamps.
6734 * Makefile.maint (cvs-sv): New macro, to be used..
6735 (config.guess-url_prefix, config.sub-url_prefix)
6736 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6737 point to CVS text checkout of Gnulib files.
6738 (copyright-check): Bump current year.
6739 (announcement): Do not hard-wire `./announce-gen'.
6740 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6741 correctly.
6742 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6743 `chmod +x'.
6744 (wget_files): Update config.guess, config.sub, texinfo.tex by
6745 `wget-update', now that their URLs work again.
6747 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6749 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6750 Problem noted by Paul D. Smith.
6752 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6754 * doc/autoconf.texi: Remove unused words from word list.
6755 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6756 .x-sc_trailing_space: New files.
6758 * doc/standards.texi: Sync from gnulib.
6760 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6761 `LIBOBJDIR' as experimental.
6763 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6764 with a target directory; it's internally implemented as `cp'
6765 anyway, but since Autoconf advertises the possibility to use
6766 a target directory when LN_S is `ln -s', we need to find out.
6767 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6768 analyzed by Keith Marshall <keith.marshall@total.com>.
6770 * THANKS: Update.
6772 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6774 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6775 confdefs.h as-is. In general, if it has backslash-newline or the
6776 like, then it doesn't work either to sort or to remove empty
6777 lines.
6779 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6781 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6783 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6785 * lib/autom4te.in (Automake-preselections): Preselect
6786 _AM_SUBST_NOTMAKE.
6788 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6790 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6791 apostrophe within a single-quoted string, as this is the usual
6792 tradition and is easier to read than '"'"'. Don't rely on the
6793 shell treating "$/" like '$/'. Use a more-consistent indenting
6794 style for the trap.
6796 2006-04-09 Eric Blake <ebb9@byu.net>
6798 * tests/autotest.at (Backquote command substitution),
6799 (Multiline backquote command substitution): Remove mistaken
6800 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6801 applied...
6802 (Parenthetical command substitution, Multiline parenthetical
6803 command substitution): here.
6805 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6807 Import macros from gnulib (often changing their name).
6809 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6810 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
6811 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

6813 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
6814 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6815 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
6816 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
6817 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6818 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6819 The manual mentions Gnulib more prominently.
6820 * doc/autoconf.texi (Gnulib): New node.
6821 (Pointers): Add Gnulib URL.
6822 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6823 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6824 Gnulib section.
6825 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6826 suggest a #define rather than a typedef for _Bool, and mention
6827 Gnulib rather than trying to substitute stdbool code.
6828 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6829 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6830 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6831 AC_STRUCT_DIRENT_D_TYPE.
6832 (Particular Types): Mention stdint.h and inttypes.h as standard
6833 headers too.
6834 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6835 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6836 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6837 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6838 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6839 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6840 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6841 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6842 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6843 (Coding Style). Don't mention m4_expand_once.
6844 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6845 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6846 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6847 (AC_CHECK_FUNCS): Use it.
6848 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
6849 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
6850 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
6851 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
6852 (AC_HEADER_ASSERT): New macro.
6853 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6854 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6855 Catch a bug in an HP-UX C compiler.
6856 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6857 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6858 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
6859 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
6860 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
6861 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6862 New macros.
6864 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6865 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6867 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6869 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6870 of the warning introduced by the 2001-08-28 change.
6872 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6873 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6875 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6876 variables shall be overriden by the cache.
6877 * tests/torture.at (AC_ARG_VAR): Test also with a first value
6878 that contains braces.
6880 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6882 Revert the patch from 2006-04-01 and only improve
6883 _AS_DETECT_BETTER_SHELL:
6885 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6886 skip nonexistent directories.
6887 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6888 only shell candidates which exist.
6889 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6890 * lib/autotest/general.m4 (AT_INIT): No need to give three
6891 parameters to _AS_PATH_WALK.
6893 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6894 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6896 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6897 distinguish m4sugar macros.
6898 * tests/tools.at (autoupdating with aclocal and m4_include):
6899 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6900 test case by Noah Misch <noah@cs.caltech.edu>.
6902 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6904 Revert my change from 2006-03-17, in other words:
6905 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6906 and DUALCASE=1.
6907 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6908 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6909 it is set.
6911 2006-04-07 Eric Blake <ebb9@byu.net>
6913 * doc/autoconf.texi (Programming in M4sh): Document that
6914 AS_MKDIR_P exits the script on failure.
6915 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6917 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6919 * config/elisp-comp, config/install-sh, config/mdate-sh,
6920 config/missing, config/mkinstalldirs: Sync from Automake.
6922 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6923 from Automake.
6925 * doc/make-stds.texi: Sync from gnulib.
6927 2006-04-06 Eric Blake <ebb9@byu.net>
6929 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6930 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6931 2006-04-01.
6933 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6934 Eric Blake <ebb9@byu.net>,
6935 Paul Eggert <eggert@cs.ucla.edu>,
6936 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6938 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6939 whether `set' quotes correctly: redirect stderr of the tested
6940 `set', and use a subshell, for Ultrix; use `sed' instead of
6941 `grep' for zsh `set' which may write binary output; match only
6942 at the beginning of a line, to avoid false positives.
6943 In order to avoid false positives by unrelated variables with
6944 multiline content, put the dump algorithm in a subshell and
6945 unset all variables containing newlines (except some which are
6946 special to the shell). Warn about cache variables that are
6947 unset.
6949 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6951 * config/config.guess, config/config.sub, config/texinfo.tex:
6952 Sync from upstream.
6954 * tests/mktests.sh: Reword comments.
6956 * tests/mktests.sh: Only skip internal macros starting with

7150 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
7151 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
7152 ac_file to the name of the default output file and call
7153 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7154 initial `rm' of the candidate files...
7155 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7156 the same list in subsequent `rm' calls, and for the temporary
7157 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
7158 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
7159 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7160 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7161 no longer needed) by libtool. Make it a cache check.
7162 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
7163 copied here by mistake.
7164 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
7165 _AC_COMPILER_EXEEXT.

7202 subordinate tools.
7203 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
7204 * doc/autoconf.texi (autoreconf Invocation): Document it.
7206 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

7294 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
7296 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7871 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize
7872 `tmp' to avoid file removal race.
7874 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7876 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7877 ac_clean_files and LIBOBJS.
7879 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7881 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
7882 Factor functionality to..
7883 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
7884 `AC_SUBST($1)' in the public version.
7885 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
7886 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
7887 ac_pt_* variables.
7889 2005-11-01 Stepan Kasal <kasal@ucw.cz>
7891 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
7892 filesystems.
7894 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7896 * NEWS: Move AH_HEADER mention to right place.
7898 2005-10-27 Stepan Kasal <kasal@ucw.cz>
7900 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
7901 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7903 2005-10-25 Stepan Kasal <kasal@ucw.cz>
7905 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
7906 conftst2.$ac_objext.
7907 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7909 2005-10-24 Stepan Kasal <kasal@ucw.cz>
7911 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
7912 conftest.o, to see whether the compiler really obeys; rm the object
7913 file before and after the test and register it with ac_clean_files.
7914 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
7916 2005-10-21 Stepan Kasal <kasal@ucw.cz>
7918 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
7919 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
7920 code so that the most common case requires less forks.
7922 2005-10-20 Stepan Kasal <kasal@ucw.cz>
7924 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
7925 not portable; thanks to Paul Eggert and Alexandre.
7927 * NEWS: Fix an old typo.
7929 2005-10-20 Jim Meyering <jim@meyering.net>
7931 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
7932 the latter'', in two places.
7934 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7936 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7937 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7938 the inner workings of AC_LANG_FUNC_LINK_TRY.
7939 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7940 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7941 by the function rather than ignoring it.
7942 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7943 comparing its address. Intel's interprocedural optimization was
7944 outsmarting the old heuristic. Problem reported by
7945 Mikulas Patocka.
7947 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7949 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

7956 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7958 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7959 before removing it (chmod -R u+rwx); there are three instances of this.
7961 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7962 Stepan Kasal <kasal@ucw.cz>
7964 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7965 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7966 make its content writable before removing it. Remove an errorneous
7967 comment from the end, where the logs of the failed tests are copied
7968 to the main log file.
7970 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7972 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7973 in case the computer is too quick. Double quote the configure.ac
7974 snippets.
7976 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7977 problems if the testsuite were running too fast.
7979 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7981 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7982 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7983 (which belong to Xt, not X itself). See Debian bug 327655.
7984 * NEWS: Mention this.
7986 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7988 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7990 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7992 * config/move-if-change: Don't output "$2 is unchanged";
7993 suggested by Ben Elliston. Handle weird characters correctly.
7995 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7997 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7998 calls, so that the final expansion of this macro is shorter.
7999 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
8000 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
8001 the cleanup there. Use AS_VAR_* macros, to be more general.
8002 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
8004 * lib/autoconf/general.m4: Use AS_IF where appropriate.
8006 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
8008 2005-09-01 Stepan Kasal <kasal@ucw.cz>
8010 * doc/autoconf.texi (Configuration Headers): Add an index entry
8011 for AH_HEADER.
8013 2005-08-26 Pavel Roskin <proski@gnu.org>
8015 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
8016 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
8017 running xmkmf.
8019 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
8021 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
8022 The previous patch didn't work, so try a better one.
8024 2005-08-26 Stepan Kasal <kasal@ucw.cz>
8026 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
8027 in the example. Reported by Bruno Haible.
8028 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
8029 "if $undefined_var;" succeeds with my shell.
8031 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
8032 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
8033 but change the m4_divert_text to m4_divert_once.
8035 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
8037 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
8038 Work around bug in Solaris /usr/xpg4/bin/awk.
8039 The bug is present in at least Solaris 8 through 10.
8041 2005-08-24 Stepan Kasal <kasal@ucw.cz>
8043 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
8044 some evil values and relying on the fact that $* concatenates the
8045 parameters by the first character from IFS.
8047 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8048 Stepan Kasal <kasal@ucw.cz>
8050 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
8051 first header appears, define AH_HEADER.
8052 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
8053 Update limitations about when to call AC_CONFIG_HEADERS.
8054 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
8055 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
8056 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
8057 ``Configuration Actions''; fix their index entries.
8059 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
8060 options correctly. Process N-M as M-N if M is smaller than N.
8061 Process ranges correctly so that N-N will run only N.
8062 Sort and uniquify the tests that will be run. If there is more
8063 than one test, reinsert the banners for the tests.
8064 * tests/autotest.at (Keywords): Unmark XFAIL.
8066 2005-08-23 Stepan Kasal <kasal@ucw.cz>
8068 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
8069 before passing the macro name to AH_TEMPLATE.
8071 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
8072 now opens log after option processing; in particular, --version
8073 and --help do not touch config.log.
8075 * Makefile.maint: Revert the change from 2005-08-12.
8077 2005-08-22 Stepan Kasal <kasal@ucw.cz>
8079 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
8080 common code to...

8085 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
8086 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
8087 Language cleanup.
8089 * doc/autoconf.texi (Defining Symbols, Changed Results):
8090 Prepend to LIBS, not append, in examples.
8092 2005-08-16 Stepan Kasal <kasal@ucw.cz>
8094 When building in place, set srcdir="."; suggested by Tim Van Holder.
8096 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
8097 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
8098 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
8099 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
8100 does not mean "no --srcdir option".
8102 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8104 * tests/autoscan.at (autoscan): New file.
8105 * tests/suite.at: Use it.
8106 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
8107 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
8109 * tests/autotest.at (Keywords): Test keywords combinations.
8111 2005-08-12 Stepan Kasal <kasal@ucw.cz>
8113 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8114 add "2>&1"; gzip 1.2.4 prints help on stderr.
8116 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8118 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8119 was pushdef'ed twice while popped only once. Push it only once.
8120 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8122 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8124 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

8129 * Makefile.maint: Update from Bison.
8131 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8132 "<tab>" in comment, so that the point is understandable.
8134 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8136 Rewrite substantial part of lib/autoconf/status.m4.
8137 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8138 and CONFIG_COMMANDS are not processed in four separate loops.
8139 Instead, there is one main loop. This alows that the common code
8140 is expanded only once, thus config.status (and configure) is smaller.
8142 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8143 the AC_LIST_FILES and cousins macros are no longer used.
8145 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8146 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8147 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8148 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8149 contain the initialization, nor the for loop, nor the associated
8150 commands; all these go to ...
8151 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8152 _AC_OUTPUT_CONFIG_STATUS.
8153 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8154 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8155 (_AC_OUTPUT_FILE): The creation of the sed script ...
8156 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8157 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8158 _AC_OUTPUT_MAIN_LOOP.
8159 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8160 _AC_CONFIG_COMMANDS): Use ...
8161 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8162 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8163 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8164 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8165 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8166 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8167 ... new macros.
8168 (_AC_CONFIG_UNIQUE): Update.
8169 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8170 Replaced by this ...
8171 (_AC_LIST_TAGS): ... new common macro.
8172 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8173 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8174 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8175 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8176 this didn't belong to the `config commands' section.
8177 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8178 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8179 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8180 to the `config commands' section either.
8181 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8182 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8184 ... and many changes to the comments nearby.
8186 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8187 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8188 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8189 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8190 (#define header templates): The comment at the top of the generated
8191 header now includes the name(s) of the source file(s).
8193 Several unrelated small changes:
8195 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8196 parameter to AC_DIAGNOSE.
8197 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8198 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8199 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8200 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8201 with AU::AC_OUTPUT.
8202 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8203 in AC_OUTPUT doesn't double-quote it either.
8204 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8205 parameters.
8207 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8209 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8210 versions of Portland Group compiler produce single- and double-quoted
8211 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8212 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8214 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8216 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8217 This is a corrected version of yesterday's patch.
8219 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8221 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8222 path, too; insert a "===" to emphasize the line.
8224 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8225 ac_cv_build_alias to ac_build_alias.
8226 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8228 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8229 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8230 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8231 (AC_ARG_VAR): ... here.
8232 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8233 target_alias.
8235 Keep a list of all precious variables and process them with one simple
8236 for loop, instead of expanding all commands, or, OTOH, complicated
8237 processing of output of "set".
8238 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8239 variable names in new macro...
8240 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8241 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8242 a loop to assign all ac_env_* and ac_cv_env_* variables.
8243 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8244 to INIT_PREPARE.
8245 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8246 its value to shell variable ac_precious_vars and call
8247 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8248 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
8249 _AC_ARG_VAR_VALIDATE.
8251 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
8252 and the AC_SUBSTs ...
8253 (AC_INIT): ... here.
8255 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
8256 the ac_subst_files section in config.log.
8258 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
8260 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

8265 * tests/c.at (C keywords): Test AC_C_TYPEOF.
8267 Fix problems reported by Nicolas Joly.
8268 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
8269 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8270 They are generated by the Tru64 v5.1B shell.
8272 2005-07-05 Stepan Kasal <kasal@ucw.cz>
8274 Fix my changes from 2005-07-01; reported by Noah Misch.
8275 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8276 description, the macro now accepts only a single tag.
8277 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
8279 Fix cases when the varsions of Autoconf and Autotest don't match.
8280 Reported by Noah Misch.
8281 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
8282 at_top_builddir, for compatibility with older autotest.
8283 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
8284 is not set, use at_top_builddir, for compatibility with older
8285 versions of autoconf.
8287 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8289 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
8290 Problem reported by Patrick Welche.
8292 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8294 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8295 sed substitution command, so that we allow | in program prefixes
8296 and program suffixes. (& is a problem anyway; we're not fixing
8297 that here.)
8298 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8299 configure_input, top_builddir, srcdir, etc.
8300 * lib/autotest/general.m4 (AT_INIT): Likewise, for
8301 PATH_SEPARATOR in AUTOTEST_PATH.
8303 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
8305 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
8306 for loop over config.site files using `set', to allow
8307 directory names containing IFS characters.
8309 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
8311 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
8312 directories with weird names. Apparently some people like living
8313 on the edge. However, improve the test that "pwd" actually does
8314 report a name for the working directory.
8315 * NEWS: Remove the claim that we test for funny chars in dir names.
8317 2005-07-01 Stepan Kasal <kasal@ucw.cz>
8319 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
8320 replaced ...

8329 about #include <config.h>.
8330 (Generic Functions): Mention the Gnulib project.
8331 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
8333 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
8334 document to output the default config_* lists to config.status.
8335 Don't recognize option --file, if the functionality is not there.
8336 Likewise for --header; moreover, recognize --he and --h as shortcuts
8337 for --help in that case.
8339 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8340 matches the order of execution. No code changed.

8362 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8363 (AC_SUBST): Call it.
8364 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8365 the directory specific variables; but don't call it for configure_input.
8367 2005-06-28 Derek Price <derek@ximbiot.com>
8369 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8370 addition.
8372 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8374 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
8375 directory have inherent problems with special characters like spaces,
8376 due to limitations in Make syntax. Problem reported by Alexandre
8377 Duret-Lutz.
8378 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
8379 Also, fix Tru64 porting problem with shell patterns,

8391 from Justace Clutter.
8392 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8393 variable into diagnostic. Make the diagnostic an error, not a warning,
8394 because we really don't support spaces and suchlike in dir names.
8395 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8396 Don't worry about backslashes in srcdir; it can't happen now.
8397 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8398 Simplify ac_optarg handling.
8399 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8409 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8410 that '\|' is not allowed in BREs; recommend using newline separated
8411 list of patterns instead of multiple -e options.
8413 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8415 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8419 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
8421 2005-06-21 Stepan Kasal <kasal@ucw.cz>
8423 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8424 b, t, r, w commands require single space, while : cannot have any.
8425 (Special Shell Variables): Fix sed code this in the example.
8426 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8427 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8429 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
8430 expand to the empty list. Don't use two pairs of m4_changequote,
8431 it's not necessary.
8433 2005-06-20 Derek Price <derek@ximbiot.com>
8435 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8437 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8439 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8440 * doc/autoconf.texi:
8441 Don't mention Solaris versions so much, if a
8442 problem is common to all extant versions of Solaris. Say "SunOS
8443 4" instead of "SunOS" for SunOS 4.
8444 (awk): Mention more of the limitations of traditional Awk.
8445 (cat): Don't talk about cat -v.
8447 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
8449 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
8450 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

8452 to be compatible with glibc strverscmp.
8453 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
8455 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8456 on Mac OS X 10.4 reported by Peter O'Gorman in:
8457 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
8458 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8459 Use shell builtins rather than 'expr', to work around expr bug.
8461 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8463 * doc/autoconf.texi: "filesystem" -> "file system".
8464 "behaviour" -> "behavior".

8466 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8467 as per POSIX.
8468 * lib/m4sugar/m4sh.m4: Likewise.
8469 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8470 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8472 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8473 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8474 to update the man page. That way, we don't have to check in new
8475 man pages every month.
8477 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8478 quotes and backslashes. Patch from Derek Price.

8482 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
8483 AS_TR_SH.
8485 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8487 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8488 -u, since it outputs chatter if the input files are the same.
8489 Problem reported by Ralf Menzel.
8491 2005-06-08 Derek Price <derek@ximbiot.com>
8493 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8494 renaming them since they are about to be redefined anyhow.
8496 2005-06-08 Derek Price <derek@ximbiot.com>
8498 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8499 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8500 Move m4_undefine to alphabetical order.
8502 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8504 * README: Recommend GNU M4 1.4.3 or later.
8505 * doc/autoconf.texi (Introduction): Likewise.
8506 Reword to avoid some formatting glitches.
8507 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8508 Clarify explanation of HP compiler bug.
8509 Redo example output tp match current CVS snapshot.
8510 Use @example.org in email addresses when the examples
8511 might get inadvertently cut-and-pasted into user code.
8512 Remove example of autom4te usage that doesn't seem to work now.
8513 Use modern AC_INIT (except when the example is meant to be
8514 shown with Autoconf 2.13).
8515 Update ksh info for Solaris 9 and later.
8516 KB -> kB.
8517 Modernize description of Automake versions a bit.
8518 Don't claim a future version of Autoconf is near.
8519 * doc/install.texi: Reword to avoid some formatting glitches.
8521 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8523 * doc/autoconf.texi: Add [] to examples, so that the manual
8524 follows its own advice about quoting better.
8525 Reword to avoid some formatting glitches.
8526 * doc/installt.exi: Reword to avoid some formatting glitches.
8528 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8529 Tru64 ksh pattern matching bug. Reported against Libtool by
8530 Albert Chin <libtool@mlists.thewrittenword.com> and
8531 Nicolas Joly <njoly@pasteur.fr>.
8533 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8535 m4_cdr of one-member list was [[]] (one-member list containing an
8536 empty string) instead of [] (an empty list. Callers were skewed to
8537 match this misbehaviour. As a consequence of this:
8538 - m4_foreach([x], [], [foo]) expanded to `foo', while
8539 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8540 This bug has been fixed:
8542 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8543 expand to an empty string; print error msg if called without
8544 an argument list.
8545 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8546 misbehaviour; handle [] and [[]] correctly.
8548 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8550 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

8552 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8554 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8556 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8557 swallow records with more than 99 fields.
8558 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8559 parse the long line.
8561 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8563 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8564 swallow literals longer than 399. Reported by Ralf Wildenhues.
8565 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8566 to workaround this limitation.
8568 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8570 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8571 to gfortran, and make these the first two compiler names
8572 checked (following the general autoconf preference for gcc).
8574 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8576 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8577 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8578 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8580 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8582 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8583 expression of unbounded size when processing the --list
8584 option. This runs afoul of a limit of 399 bytes per regular
8585 expression on AIX. Problem reported by Ralf Wildenhues.
8587 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
8589 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
8590 * doc/autoconf.texi (Particular Headers): Reword example
8591 for multiline stdbool replacement.
8592 (Setting Output Variables): Reword text a bit. Don't
8593 give all the details about |#_!!_#|.
8594 Reword description of line replacement.
8596 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8598 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8599 now contain newlines, and substituted files must be referenced on
8600 a line alone; the sed scripts to substitute them are now very
8601 different.
8602 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8603 commands can be put in a sed script portably.
8604 * doc/autoconf.texi (Setting Output Variables): Document above
8605 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8606 use of multiline substitution.

8616 * tests/local.at: Don't attempt to check for negated character
8617 classes in shell scripts. The test was too brittle.
8619 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8621 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8622 * doc/autoconf.texi (Limitations of Builtins): Document this
8623 limitation.
8625 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8627 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8628 common code; used in many places in the tree.

8630 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8632 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
8634 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
8635 messages when ac_unique_file is not found.
8636 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8637 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8638 commands, for consistency with AC_MSG_ERROR and such.
8640 * bin/autoconf.as: Make more use of "shift 2" in option processing.

8650 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8652 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8653 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8654 (ac_top_builddir): ... this ...
8655 (ac_top_build_prefix): ... to this; the old name is also kept, for
8656 backward compatibility.
8657 (ac_top_builddir_sub): New variable, without the trailing slash,
8658 always nonempty.
8659 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8660 * doc/autoconf.texi (Configuration Actions): Rename
8661 ac_top_builddir to ac_top_build_prefix.
8662 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8663 at_top_builddir to at_top_build_prefix.

8671 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8673 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8674 argument to m4_foreach. I guess it was necessary in the past,
8675 but I think it's a no-op now.
8677 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8679 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8680 ``cat <<_ACEOF'' commands to one.
8681 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8682 * lib/autoconf/status.m4: On various places, use expr instead of
8683 ``echo|sed.''
8684 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8685 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8686 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8687 a range.
8688 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8689 the wrong patterns between ``case'' and ``esac.'' The previous
8690 code had false positives.
8692 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8694 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8695 as on 2005-05-02.
8696 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8697 Mention LIBOBJDIR.

8758 * doc/autoconf.texi (Autoconf Language): Be more precise about
8759 quoting rules. Problems noted by Stepan Kasal.
8760 Also, throughout this document, be more careful about white space.
8761 "blank", "white space", and "space" all have different meanings
8762 and we should be careful to say what we mean.

8769 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
8770 avoid problems with C++ and throw.
8771 * tests/compile.at: .cpp, not .cc.
8773 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
8775 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8777 * doc/autoconf.texi (Generic Functions): Typos.
8779 2005-05-02 Gary V. Vaughan <gary@gnu.org>
8781 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
8782 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
8783 set by latest automake.
8785 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8787 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
8788 outputs 0 on GNU/Linux these days.
8790 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
8792 * doc/autoconf.texi (Autoconf Language): Add more description
8793 about quoting heuristics.
8794 (Limitations of Builtins): Describe "set -" problems.
8796 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8798 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
8799 not newline.
8801 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8802 by AC_DEFINE; it was a mistake.
8803 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8805 2005-04-25 Stepan Kasal <kasal@ucw.cz>
8807 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
8809 2005-04-22 Stepan Kasal <kasal@ucw.cz>
8811 * doc/autoconf.texi (External Software): Quadrigraphs are not
8812 processed correctly in AS_HELP_STRING; avoid this in the examples.
8813 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8814 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8815 comment and reduce m4_default([foo], []) to [foo].
8816 (m4_strip): Update the explanation.
8818 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8820 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8821 Remove core.conftest.* too; it's generated by Tru64 5.1.
8822 Problem reported by Jennis Pruett.
8823 * lib/autoconf/functions.m4
8824 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8825 Don't bother to remove core files; AC_RUN_IFELSE should do that
8826 for you.
8828 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8830 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8847 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8849 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8850 as well as configure.in. Problem reported by Gregorio Guidi.
8852 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8854 * doc/autoconf.texi (Particular Functions): Use gnulib's current

8870 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8872 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8873 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8874 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8875 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8876 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8878 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8880 * NEWS: The configure command now warns you if you attempt to use
8881 a directory whose name contains a special character like space,
8882 newline, or "\".
8883 * doc/autoconf.texi (Installation Directory Variables): Allow
8884 "," in file names. Do not use \@; it's not a portable regexp.
8885 * bin/Makefile.am (edit): Likewise.
8886 * lib/Makefile.am (edit): Likewise.
8887 * tests/Makefile.am (edit): Likewise.
8888 * tests/semantics.at: Likewise.
8889 * tests/torture.at: Likewise.
8890 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
8891 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
8892 * doc/autoconf.texi (File System Conventions): Warn about
8893 unportable file names.
8894 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8895 (AC_INIT): Use it.
8896 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8897 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8898 ac_pwd, and quote srcdir.
8899 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8901 * doc/autoconf.texi: Fix some systematic formatting problems.
8902 ".)" needs a following @: if not at the end of a sentence, and
8903 similarly for "!)". "etc." should be preceded by a comma.
8904 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8906 2005-03-22 Bruno Haible <bruno@clisp.org>
8908 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8909 argument is often called 'build-aux'.
8911 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8913 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8914 macro AC_TRY_LINK is obsolete.
8915 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8916 `AC_CONFIG_FILES'.
8918 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8920 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8921 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8922 from a Common Lisp's `cl'.
8923 (AC_PROG_CXX): Behave according to the documentation: don't
8924 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8925 make the variable CCC precious; use `cl.exe', not `cl'.
8927 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8928 Alexandre Duret-Lutz <adl@gnu.org>
8930 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8931 /dev/null, as "configure" shouldn't read stdin, and this insulates
8932 us from problems (e.g., when testing for "cl"). Also, do this
8933 redirection before invoking "hostname" or "uname", and keep the
8934 original input stream available via...
8935 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8936 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8937 bother with "</dev/null" since it's now done at the top of
8938 'configure'.
8939 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8940 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8941 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8942 * doc/autoconf.texi (File Descriptor Macros): New section.
8943 (Printing Messages): Mention it.
8944 * tests/base.at (Input/Output): New test.
8946 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8948 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8949 newline if neither \c nor -n work, as that would output two
8950 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8952 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8954 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8955 This causes that any required macros inside will get before the if.
8956 * doc/autoconf.texi (autom4te.cache): A typo.
8958 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8960 Undo previous change, except keep the change to
8961 lib/autoconf/programs.m4 that replaced grep with shell
8962 pattern-matching. This is because net-snmp configure reads stdin.
8963 Reported by Noah Misch.
8965 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8967 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8968 from /dev/null, as "configure" shouldn't read stdin, and this
8969 insulates us from problems (e.g., when testing for "cl").
8970 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8971 before invoking "hostname" or "uname".
8972 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8973 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8974 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8975 "</dev/null" since it's now done at the top of 'configure'.
8976 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8977 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8978 Also, replace grep with shell pattern-matching, to save a process.
8980 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8982 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8983 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8984 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8985 compiler.
8987 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8989 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8990 grep -q isn't portable. Improve grep -s explanation.
8991 Problem reported by Dan Manthey.
8993 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8995 * doc/autoconf.texi (Special Shell Variables): Clarify
8996 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8998 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
9000 * doc/autoconf.texi: Use @acronym for DJGPP.
9001 Fix some @code's that should have been @env's, and vice versa.
9002 Sort environment variable names.
9003 Mention that shells no longer inherit IFS.
9004 Don't recommend PATH_SEPARATOR=';' so strongly.
9005 Mention that $RANDOM might expand to the empty string.
9006 "symlink" and "soft link" -> "symbolic link".
9007 Improve mktemp description (reported by Bruno Haible).
9009 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
9011 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
9012 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
9013 Likewise.
9014 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
9015 Likewise.
9017 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
9019 * NEWS: Mention AT_COPYRIGHT.
9021 * tests/local.at (AT_CMP): Use diff directly on input files rather
9022 than copying them.
9024 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
9025 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
9027 2005-02-04 Noah Misch <noah@cs.caltech.edu>
9028 and Paul Eggert <eggert@cs.ucla.edu>
9030 * tests/autotest.at (Empty test suite): New test.
9031 * tests/torture.at (Substitute and define special characters)
9032 (Substitute a 2000-byte string, Define to a 2000-byte string)
9033 (Substitute a newline, Define a newline): New tests.
9035 2005-02-04 Noah Misch <noah@cs.caltech.edu>
9037 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
9038 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
9039 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
9040 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
9041 (Standard regular expressions): New test.
9042 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
9043 excess test name quoting.
9044 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
9045 CPPFLAGS to `configure' instead of setting it in `configure'.
9047 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
9048 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
9049 on some platforms.
9051 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
9052 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
9054 * tests/local.at (AT_CMP): New macro.
9055 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
9056 (AC_SAVE_STATE): Move environment grep...
9057 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
9058 (AT_CONFIG_CMP): New macro.
9059 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
9060 * tests/c.at (Extensions): Do not exit early.
9061 * tests/atlocal.in: Inherit $GREP.
9063 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
9064 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
9066 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
9067 (AC_COPYRIGHT): Factor header comment portion out and move into...
9068 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
9069 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
9070 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
9071 --version output.
9072 * tests/local.at: Add Autoconf test suite copyright notice.
9073 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
9075 2005-02-04 Bruno Haible <bruno@clisp.org>
9076 and Paul Eggert <eggert@cs.ucla.edu>
9078 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
9080 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
9082 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
9083 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
9085 Try not to generated lines of unlimited length, as POSIX places a
9086 2047-byte limit on line length of portable text files.
9087 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
9088 Use newline as a separator, not space.
9089 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
9090 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
9091 space.
9093 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9095 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
9096 as_func_*. Add test to check whether positional parameters
9097 are restored after function return.
9099 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
9101 * doc/autoconf.texi (Special Shell Variables): Mention _,
9102 BIN_SH, DUALCASE. Say that variables other than "status" are safe
9103 if they contain a lower-case letter. The DUALCASE problem was
9104 reported by Ralf Wildenhues.
9106 * bin/autoconf.as: Don't exit with status 0 after write failure
9107 with --help or --version.
9108 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
9109 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
9111 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9113 * doc/autoconf.texi (Limitations of Usual Tools):
9114 Unicos 9 sed limitations.
9115 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
9116 to get the option-enhanced interface on older Crays. Try ftn for
9117 Fortran 95 (newer Crays).
9119 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
9121 * man/Makefile.am (.x.1): Go back to the simple solution, but take
9122 care to echo the commands, so the user knows what's going on.
9123 Modified from a suggestion by Stepan Kasal.
9125 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
9126 with a cross reference. Derived from a suggestion by Bruce Korb.
9128 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
9130 * doc/autoconf.texi (config.status Invocation): Warn about
9131 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
9132 * doc/install.texi (Defining Variables): Likewise.
9133 Based on a proposed patch by Ralf Wildenhues.
9135 * man/Makefile.am (.x.1): Make sure the required generated files
9136 are up to date. Problem and original solution proposed by Stepan Kasal.
9137 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
9138 implicit-man-prerequisites): New rules, used by the above.
9140 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
9141 * config/config.guess, config/config.sub, config/install-sh: Likewise.
9142 * config/missing, config/texinfo.tex: Likewise.
9144 2005-01-29 Stepan Kasal <kasal@ucw.cz>
9146 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9147 Update the long comment explaining it.
9149 m4_require no longer writes an ``is required by'' line to the
9150 execution stack. It contains only one bit of non-redundant
9151 information: that the macro was required, not called. And even
9152 this bit is useless in most situations: have you ever met a macro
9153 which both calls and requires the same macro?
9155 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9156 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9157 macro.
9158 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9159 (m4_expansion_stack_pop): Remove the misplaced comment.
9160 (m4_require): Don't put the ``is required by'' line to the
9161 execution stack; slightly improve the out-of-a-defun error message.
9162 (_m4_divert_grow): New macro, counter for the temporary diversions.
9163 (_m4_require_call): Use it.
9164 * tests/m4sugar.at (m4_require): Expect output without the
9165 ``is required by'' messages.
9167 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9169 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
9170 rather than x for expr.
9172 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
9173 this is safe.
9174 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
9175 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9176 * lib/autotest/general.m4 (AT_INIT): Likewise.
9177 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Likewise.
9178 * tests/mktests.sh: Likewise.
9180 2005-01-27 Akim Demaille <akim@epita.fr>
9182 Have autoheader honor --force.
9184 * doc/make-stds.texi, doc/standards.texi: Update from masters.
9185 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
9186 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
9187 from masters, so that FileUtils.pm's update_file provide --force
9188 support.
9189 * bin/autoheader.in: Pass $force to update_file so that
9190 config.h.in is always recreated when --force.
9192 2005-01-24 Stepan Kasal <kasal@ucw.cz>
9194 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
9196 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9198 * doc/autoconf.texi (Limitations of Builtins): Clarify that
9199 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
9201 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
9203 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
9204 Warn about newline stripping in `` and $(). Update Solaris
9205 version to 9.
9206 (Limitations of Builtins): Use expr "X...", not expr "x...", as
9207 X insulates us from future changes to Posix.
9208 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
9209 stripping.
9211 2005-01-19 Stepan Kasal <kasal@ucw.cz>
9213 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

9575 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9576 "char c = '\200';" rather than "char c = 0x80;" as the

9680 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
9681 Problem reported by Stepan Kasal.
9683 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
9685 Fix problems reported by Andreas Buening in:
9686 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
9687 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
9688 in test makefile.
9689 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
9690 readable; it's not true in OS/2-emx.
9692 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
9694 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
9695 "/usr/include", clear ac_x_includes instead of leaving it as "no"
9696 (trivial change). Problem and patch reported by Andrew Church in:
9697 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
9699 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
9701 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
9702 three args in examples. Problem reported by Frederik Fouvry in:
9703 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
9704 Also, fix some minor spacing and punctuation bugs.
9706 2004-09-02 Akim Demaille <akim@epita.fr>
9708 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
9709 "case" to restore ordering.
9710 Reported by Stepan Kasal.
9712 2004-08-26 Akim Demaille <akim@epita.fr>
9714 * doc/autoconf.texi: Minor typos and stylos.

9726 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9727 texinfo.tex for now (done by hand now).
9728 * Makefile.maint (wget_files, cvs_files):
9729 Remove ansi2knr.c; nobody uses it.
9730 (ansi2knr.c-url_prefix): Remove.
9731 (cvs-update): Fix test for failure. I don't know why it ever
9732 worked...
9734 * doc/autoconf.texi: Update URLs, some of which went stale.
9735 Use @uref rather than @href.
9737 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9738 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9740 * config/config.guess, config/config.sub, config/elisp-comp,
9741 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9742 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9744 * NEWS, TODO, configure.ac, bin/autoscan.in,
9745 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
9746 doc/install.texi, lib/Autom4te/Configure_ac.pm,

9750 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9751 tests/tools.at, tests/torture.at:
9752 Use "file name" rather than "filename" or "path",
9753 to be consistent with the terminology of the GNU coding standards.
9755 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9757 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9758 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9759 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9760 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9762 More fixes to support spaces in the name of the build directory.
9763 This isn't a complete fix but it's an improvement.
9765 * bin/autoconf.as (autom4te_options): New var.
9766 Use it instead of appending to AUTOM4TE, so that we can allow
9767 spaces in the build directory's absolute name.
9768 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9769 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9770 AT_CHECK_NOESCAPE): Likewise.
9771 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9772 main program): Likewise.
9774 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9776 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
9777 From Ralf Corsepius in:
9778 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
9780 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
9782 * doc/autoconf.texi (Function Portability): Document isinf and
9783 and isnan. From a suggestion by Kevin Ryde.
9785 * lib/Autom4te/General.pm (END): Return correct exit status even
9786 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9788 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9790 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9791 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9792 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9794 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9796 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9797 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9798 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9799 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9800 * lib/autom4te.in (Automake-preselections): Preselect
9801 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9803 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9805 * lib/autom4te.in (Automake-preselections): Preselect
9806 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9807 trace them.
9809 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9811 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9812 Tru64.
9813 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9814 Document problem with "`""`" in pdksh POSIX mode.
9816 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9818 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9819 with pdksh, too. Problem reported by Patrick Welche via
9820 Gary V. Vaughan.
9821 * doc/autoconf.texi (Shellology): Note that set -o posix is
9822 useful for pkdsh, too.
9824 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9826 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9827 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9828 Don't fail if ENV or BASH_ENV is readonly.
9829 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9830 etc. are read only. Problem reported by Ludovic Courtes.
9832 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9834 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9835 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9836 (trivial change)
9838 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9840 * doc/autoconf.texi (File System Conventions): Warn about
9841 names like "aux". Problem reported by Eric Blake.
9843 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9844 by zero instead of array size, so that we can use any arithmetic
9845 constant expression (instead of requiring an integer constant
9846 expression). This allows us to test expressions like DBL_MAX <
9847 LDBL_MAX, which didn't conform to the C standard using the old
9848 method.
9849 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9850 now that we can do floating-point tests at compile time.
9852 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9854 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9855 and LDBL_EPSILON, as the resulting expression isn't an
9856 integer constant expression and violates the C standard.
9857 Problem reported by Nelson H. F. Beebe. Also, check
9858 for "L" suffix, and check that long double doesn't have
9859 worse range or precision than double, that mixed-mode
9860 arithmetic doesn't generate a diagnostic, that double
9861 constants fit in long double.
9863 2004-06-03 Kevin Ryde <user42@zip.com.au>
9865 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9866 malloc(0) and realloc(NULL,size).
9868 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9869 Bob Proulx.
9871 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9873 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9874 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9875 by Jim Meyering.
9877 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9879 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9880 can be rewritten using if-then-else. Suggested by Bruno Haible.
9882 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9884 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9885 Problem reported by Stepan Kasal.
9887 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9889 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9890 change). Patch reported by Ralf Wildenhues in
9891 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9893 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9894 function F exists if the compiler and linker let you compile an
9895 expression like (F != 0). Recent versions of GCC optimize away
9896 the reference to F in that case, since every function address must
9897 be nonzero, so the link succeeds even if F does not exist.
9898 Problem reported by Manu in
9899 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9901 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9902 "Unix". Many uses changed.
9903 (Limitations of Builtins): Explain better why the ! command isn't
9904 portable.
9906 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9908 * lib/autom4te.in (Automake-preselections): Preselect
9909 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9911 2004-05-19 Kevin Ryde <user42@zip.com.au>
9913 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9914 referencing AC_FUNC_STRERROR_R.
9916 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9917 note pessimistic assumption when cross compiling.
9919 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9921 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9922 (until 2004) invoked subcommands with sh -e, contra POSIX.
9923 Reported by Kevin Ryde.
9925 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9927 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9928 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9929 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9930 `test -f " /usr/bin/grep"', which _always_ failed.
9931 (AC_PROG_SED): Ditto bogus PATH fix.
9932 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9933 requires that grep correctly supports _multiple_ `-e' options, rather
9934 than stating only that grep should accept `-e'.
9936 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9938 Port to C99, which requires that 'exit' be declared.
9940 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9941 to ensure that stdlib.h is included.
9942 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9943 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9944 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9945 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9946 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9947 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9948 when using 'exit' in a test; C99 requires that 'exit' be declared.
9950 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9952 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9953 now prefers 'grep' implementations that accept -e.
9954 (Limitations of Usual Tools): Describe problems of traditional
9955 egrep and fgrep with long input lines, and of traditional grep
9956 with -e.
9957 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9958 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9959 All callers changed. Append /usr/xpg4/bin to the PATH, for
9960 Solaris.
9961 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9962 the user with complaints about multiple -e options.
9963 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9964 Define it with AC_PROG_GREP.
9965 * configure.ac (AC_PROG_GREP): Add.
9966 * lib/freeze.mk (GREP): New macro.
9968 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9970 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9971 a possible candidate only after all others fail, rather than
9972 consulting it first. This improves backward compatibility by
9973 better reflecting the way shell selection occurred in previous
9974 versions of Autoconf, and should help to avoid triggering latent
9975 problems in other packages, such as the one in Automake where zsh
9976 is not handled robustly:
9977 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9978 Although it is not Autoconf's responsibility to work around
9979 problems in Automake, it nevertheless makes sense to avoid
9980 introducing unnecessary incompatibilites.
9982 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9983 Gary V. Vaughan <gary@gnu.org>
9985 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9986 how deeply nested we are when a suitable tool is found, set the
9987 ac_path_TOOL_found flag.
9988 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9989 nested we are in this macro. Break out of all 3 nested loops if
9990 ac_path_TOOL_found is set.
9992 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9994 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9995 of the _AS_PATH_WALK loop too if GNU flavor is found.
9997 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9999 * doc/autoconf.texi (Limitations of Make): Update documentation
10000 for `$<'. New entry `Long lines', based on a report from Simon
10001 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
10002 paragraph about DJGPP, based on a mail from Richard Dawe.
10004 2004-04-20 Paul Eggert <eggert@twinsun.com>
10006 * tests/c.at (C keywords): Don't assume that GCC supports
10007 "restrict" and "inline", as sufficiently-old GCC versions do not
10008 (also, GCC configured to be in pedantic C89 mode does not).
10009 Problem reported by Sumit Pandya in:
10010 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
10012 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
10013 consider -g to work if it generates warnings when plain compiles
10014 don't. Problem reported by Braden McDaniel in:
10015 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
10017 * doc/autoconf.texi (Slashes): New section, to document a problem
10018 reported by Jim Meyering in:
10019 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
10021 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
10022 linker output files before linking, to work around IRIX 6 linker bug.
10023 Problem reported by Rainer Orth in:
10024 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
10026 2004-04-20 Gary V. Vaughan <gary@gnu.org>
10028 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
10029 best tool so far counter rely on the tool path variable name to
10030 avoid checks for one tool being affected by the results of running
10031 the length check on a previous tool.
10033 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
10034 match expression argument, as different greps have different
10035 regular expression flavours.
10036 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
10037 literals.
10038 (AC_PROG_EGREP): Pass 'EGREP$'.
10039 (AC_PROG_GREP): Pass 'GREP$'.
10041 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
10043 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
10044 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
10046 2004-03-29 Paul Eggert <eggert@twinsun.com>
10048 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
10049 Types, Specific Compiler Characteristics, System Services,
10050 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
10051 etc. consistently instead of 'long', 'short', 'unsigned' etc.
10052 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
10053 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
10054 Likewise.
10055 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
10056 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
10057 AC_TYPE_OFF_T): Likewise.
10058 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
10059 Likewise.
10061 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
10062 pacify libtool 1.5.2. Fix quoting problems in sed command.
10064 2004-03-28 Paul Eggert <eggert@twinsun.com>
10066 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
10067 now defines HAVE_DECL_TZNAME if it is declared, when
10068 HAVE_STRUCT_TM_TM_ZONE is not defined.
10069 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
10070 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
10071 for HAVE_TZNAME.
10073 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
10075 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
10076 superfluous backslashing of quotes (") in sed expressions;
10077 thanks to Paul Eggert.
10079 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
10081 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
10082 Fortran compiler is ifort, also added pghpf; thanks to Nelson
10083 H. F. Beebe for the bug report.
10085 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
10087 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
10088 quoted -cmdline argument in Portland Group compiler (bug
10089 reported by Jeffrey J. Barteet).
10091 2004-03-25 Kevin Ryde <user42@zip.com.au>
10093 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
10094 (Run Time): ... here, where it's now mentioned.
10096 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
10098 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
10099 inherits from language Autoconf-without-aclocal-m4.
10100 (Customizing autom4te): Adjust example; the cache must now be
10101 disabled for language Autoconf-without-aclocal-m4.
10103 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
10104 Nathanael Nerode <neroden@twcny.rr.com>
10106 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
10107 AC_CHECK_TOOLS): Warn if a cross-tool is found without
10108 a prefix.
10109 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
10110 AC_CHECK_TARGET_TOOLS): New macros.
10111 * doc/autoconf.texi (Generic Programs): Document
10112 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
10113 AC_CHECK_TARGET_TOOLS, and warn for future changes
10114 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
10115 AC_CHECK_TOOLS.
10116 (Specifying Names): Document the reason for these future
10117 behavioral changes.
10118 * tests/mktests.sh: Do not generate tests for the
10119 new macros.
10120 * NEWS: Document these changes.
10122 * doc/autoconf.texi: Avoid macros with unbraced arguments,
10123 they make TeX hang up.
10125 2004-03-15 Paul Eggert <eggert@bogus.example.com>
10127 * NEWS: New macro AC_CHECK_ALIGNOF.
10128 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
10129 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
10130 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
10131 vowel.
10132 (AC_CHECK_ALIGNOF): New macro.
10133 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
10134 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
10135 those for sizeof.
10137 2004-03-03 Paul Eggert <eggert@twinsun.com>
10139 * bin/Makefile.am (edit): Don't use $< in a context where
10140 POSIX doesn't require support for it. Use $@.in instead.
10141 Problem reported by Anthony N. Frasso in
10142 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
10143 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

10148 from the next generation of Libtool.
10149 * lib/autom4te.in (Autoreconf-preselections): Ditto.
10151 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10153 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
10154 is not always thread-safe. Report from Nathanael Nerode.
10156 2004-02-18 Paul Eggert <eggert@twinsun.com>
10158 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10159 problem on QNX reported by Stephen Rasku in
10160 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
10162 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10163 $(m4sh_m4f_dependencies); this removes a FIXME.
10164 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10165 (MAINTAINERCLEANFILES): Split into pieces,
10166 one per related section. Add $(srcdir)/wrapper.in.
10168 2004-02-09 Paul Eggert <eggert@twinsun.com>
10170 * doc/autoconf.texi (Setting Output Variables): Emphasize that
10171 AC_SUBST provides no portable way to escape literal newlines.
10173 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10174 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10175 Darwin uses -lcrt2.o and there's little point to cataloging all
10176 the system variants. Partial fix reported by Andreas Waechter in:
10177 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
10178 for bug reported by Nelson H. F. Beebe in:
10179 http://mail.gnu.org/archive/html/bug-autoconf/2003-12/msg00090.html
10181 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
10183 * doc/autoconf.texi (AU_DEFUN): Fix English,
10184 suggested by Paul Eggert.
10185 * lib/autoconf/autoupdate.m4: Correct reference to
10186 acobsolete.m4, suggested by Alexandre Duret-Lutz.
10188 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
10190 * bin/autoupdate.in: Define __file__ so that warnings
10191 refer to the correct file.
10192 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
10193 the behavior of the third argument.
10194 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
10195 correctly the behavior of the third argument. Document
10196 what the three macros that AU_DEFUN defines do. Fix
10197 warning message when the third argument includes $0
10198 (reported by Alexandre Duret-Lutz).
10200 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10201 Eric Sunshine <sunshine@sunshineco.com>
10202 Paul Eggert <eggert@twinsun.com>
10204 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

10206 parameter. Expand _AS_SHELL_FN_SPY.
10207 (AS_INIT_WITH_SHELL_FN): Removed.
10208 (_AS_SHELL_FN_SPY): New macro.
10209 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
10210 macros.
10211 (AS_SHELL_SANITIZE): Remove loop to find better shell
10212 and documentation for the parameter.
10213 (_AS_DETECT_BETTER_SHELL): Move it here.
10214 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
10215 (_AS_RUN): Move it here, support testing with eval.
10216 (AS_REQUIRE_SHELL_FN): Require shell functions when
10217 it is used.
10218 (_AS_LINENO_WORKS): Put around braces, we do not
10219 trigger the bash bug anymore.
10220 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10221 use AS_INIT_WITH_SHELL_FN.
10222 * bin/autoconf.in, tests/wrapper.in: Regenerated.
10224 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10226 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
10227 * doc/autoconf.texi: Don't say that the third parameter
10228 is broken.
10229 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
10230 (AU_DEFUN): Honor the third parameter, create autoupdate
10231 macros with AU_DEFINE.
10232 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
10233 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
10234 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
10235 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
10236 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
10237 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
10238 AC_XENIX_DIR): Likewise.
10239 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
10240 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
10241 * lib/autoconf/status.m4: Remove FIXME.
10242 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
10243 that the macro is not present anymore in the updated
10244 configure.ac.
10245 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
10246 of autoupdate.
10248 2004-01-28 Paul Eggert <eggert@twinsun.com>
10250 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
10251 copyright years.
10252 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
10253 2003 (except 1997) to the list of copyright years. This undoes
10254 the 2003-05-22 change, which removed the older years from the list.
10255 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
10257 2004-01-27 Gary V. Vaughan <gary@gnu.org>
10258 Albert Chin-A-Young <china@thewrittenword.com>
10260 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
10261 grep or ggrep program in PATH that accepts as long lines as
10262 possible.
10263 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
10264 AC_PROG_GREP.
10265 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
10266 egrep and fgrep respectively if $GREP -E/-F don't work.
10267 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10268 _AC_PROG_GREP, and AC_PROG_SED.
10269 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10270 longest input length accepted by a command.
10271 (AC_PROG_SED): Use it.
10272 * doc/autoconf.texi (Particular Programs): Document the changes.
10273 * NEWS: Updated.
10275 2004-01-27 Paul Eggert <eggert@twinsun.com>
10277 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
10278 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10279 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
10280 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
10282 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
10283 bin/autoconf.in, config/Makefile.in, config/config.guess,
10284 config/config.sub, config/install-sh, config/mdate-sh,
10285 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,
10286 lib/Makefile.in, lib/Autom4te/Makefile.in,
10287 lib/autoconf/Makefile.in, lib/autoscan/Makefile.in,

10295 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
10296 tests/actypes.at: Regenerate and/or sync with original
10297 sources.
10299 2004-01-26 Paul Eggert <eggert@twinsun.com>
10301 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10302 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10303 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10304 not <inttypes.h>. Problem reported by Tim Mooney in
10305 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10306 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10307 Likewise.
10309 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10310 otherwise "make check" fails because it forbids cmp (I guess
10311 because cmp treats files as binary on DOS-like systems).
10313 * tests/mktests.sh: Update copyright date to 2004, since some tests
10314 have changed in 2004.
10316 2004-01-23 Gary V. Vaughan <gary@gnu.org>
10318 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
10319 non-truncating sed or gsed program in PATH.
10320 * tests/acprograms.at: Add it.
10321 * doc/autoconf.texi (Particular Programs): Document it.
10322 * NEWS: Updated.
10324 2004-01-15 Paul Eggert <eggert@twinsun.com>
10326 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10327 -std1 disables some useful extensions on Tru64. Problem reported
10328 by N. Lichtmaier in
10329 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10331 2004-01-14 Paul Eggert <eggert@twinsun.com>
10333 * doc/autoconf.texi (Programming in M4sh): Document that
10334 AS_MKDIR_P succeeds if the destination is a symbolic link
10335 to an existing directory.
10336 (Limitations of Usual Tools): Note that mkdir -p might not
10337 succeed on symlinks to directories.
10339 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10341 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10342 * bin/autoheader.in: Grammar fix in message.
10343 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10344 Test for dir before calling mkdir -p. (trivial changes)
10346 2004-01-13 Eric Blake <ebb9@byu.net>
10348 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10349 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10351 2004-01-10 Jim Meyering <jim@meyering.net>
10353 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10355 2004-01-09 Paul Eggert <eggert@twinsun.com>
10357 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10358 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10359 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10360 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10361 AC_COMPILE_IFELSE, since we now assume our caller invokes
10362 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10363 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10364 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10365 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10367 2004-01-07 Paul Eggert <eggert@twinsun.com>
10369 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10370 `"'...'"`, as it's confusing (and I suspect it may not work on
10371 some platforms). The code was incorrect anyway, as it assumed
10372 that \$ evaluated to itself in that context. Reported by
10373 Alexandre Duret-Lutz.
10375 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10377 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10378 and _LT_AC_TAGCONFIG.
10380 2004-01-06 Paul Eggert <eggert@twinsun.com>
10382 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10383 example, and add more examples. Reported by Eric Sunshine.
10385 2004-01-05 Paul Eggert <eggert@twinsun.com>
10387 * doc/autoconf.texi (Limitations of Usual Tools):
10388 Remove warning against "rm -fr" introduced yesterday; it
10389 was a false alarm.
10391 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
10392 autoscan, autoupdate, ifnames): Don't use chmod -w.
10393 * lib/Makefile.am (autom4te.cfg): Likewise.
10394 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
10395 "chmod -w".
10397 2004-01-04 Paul Eggert <eggert@twinsun.com>
10398 Paolo Bonzini <bonzini@gnu.org>
10400 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
10401 by doing lineno substitution only on lines containing "$LINENO".
10403 2004-01-04 Paul Eggert <eggert@twinsun.com>
10405 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10406 Use "rm -f" to remove conftest.sed, not plain "rm".
10407 Bug reported by David Relson in
10408 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10410 * Makefile.am (autom4te-update):
10411 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10412 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10413 * doc/autoconf.texi (Guidelines): Likewise.
10414 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
10415 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.
10416 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10417 * lib/autotest/general.m4 (AT_INIT): Likewise.
10418 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
10419 * tests/Makefile.am (clean-local): Likewise.
10420 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
10421 srcdir): Likewise.
10422 * doc/autoconf.texi (Limitations of Usual Tools):
10423 Warn against "rm -fr".
10425 2004-01-03 Paul Eggert <eggert@twinsun.com>
10427 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10428 -c -o might not work. From a suggestion by Kevin Ryde.
10429 (C Compiler, Generating Sources, Limitations
10430 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10431 Don't put '-o' after non-options, as POSIX doesn't allow this.
10432 Mention that cc's name might be gcc or c89 or whatever.
10434 2004-01-04 Kevin Ryde <user42@zip.com.au>
10436 * doc/autoconf.texi: Add various further index entries.
10438 2003-12-29 Paul Eggert <eggert@twinsun.com>
10440 * bin/autoreconf.in (autoreconf_current_directory):
10441 Fix typo: mkdir without umask arg.
10443 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10445 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10446 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10447 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10448 explanation clearer.
10450 2003-12-24 Andreas Schwab <schwab@suse.de>
10452 * doc/autoconf.texi (Default Includes): Fix misspelling of
10453 AC_INCLUDES_DEFAULT.
10455 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10457 * configure.ac: Test if sh -n works.
10458 * configure: Regenerate.
10459 * tests/atlocal.in: Store the result here.
10460 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
10461 tools.at, looking in atlocal's ac_cv_sh_n_works instead
10462 of explicitly testing.
10463 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10464 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10465 * tests/tools.at (Syntax of the shell scripts): Simplify
10466 using AT_CHECK_SHELL_SYNTAX.
10467 (Syntax of the Perl scripts): Remove definition of
10468 AT_CHECK_PERL_SYNTAX.
10470 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10472 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
10473 stderr to /dev/null.

10475 * bin/wrapper.in: Regenerate.
10477 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
10479 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
10480 Extracted from AS_SHELL_SANITIZE.
10481 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
10482 macros.
10483 (AS_SHELL_SANITIZE): Move reinvocation code from
10484 _AS_LINENO_WORKS, use it to find out if shell
10485 functions work.
10486 (_AS_LINENO_WORKS): Don't find another shell if $LINENO

10495 and tests/testsuite.
10497 2003-11-24 Akim Demaille <akim@epita.fr>
10499 * config/announce-gen (&print_locations, &print_signatures)
10500 (&sizes): New.
10501 Use them.
10502 No longer rely on Gnus to inline the list of signatures: compute
10503 them on the fly.
10505 2003-11-24 Akim Demaille <akim@epita.fr>
10507 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
10508 override some files.
10509 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
10510 From Debian Autoconf 2.58.
10512 2003-11-24 Akim Demaille <akim@epita.fr>
10514 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote $ac_popdir
10515 uses.
10516 From Debian Autoconf 2.58.
10518 2003-11-24 Paolo Bonzini <bonzini@gnu.org>
10520 * TODO: Remove already done things. Update the part about finding
10521 tools for the target.
10523 2003-11-24 Paolo Bonzini <bonzini@gnu.org>
10525 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H, AC_DIR_HEADER):
10526 Make wording more consistent.
10527 * lib/autoconf/specific.m4 (AC_CYGWIN, AC_EMXOS2, AC_MINGW32):
10528 Explain the transition better.
10529 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS): Explain
10530 the transition better.
10532 2003-11-24 Paolo Bonzini <bonzini@gnu.org>
10534 * doc/autoconf.texi (Obsoleting Macros): Don't document the third
10535 parameter of AU_DEFUN.
10536 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
10537 (AU_DEFUN): Remove the third parameter, it was not used.
10538 Use AC_DEFUN directly, not AU_DEFINE.
10539 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into

10717 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10719 2003-10-10 Andreas Schwab <schwab@suse.de>
10721 * bin/autoheader.in: Avoid empty first line in --version and
10722 --help output.

10733 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10734 -mGLOB_options_string stuff for Intel ifc, which can cause
10735 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10736 pattern-matching instead of grep.
10738 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>

10748 * NEWS: Updated.

10756 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10758 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10759 cache variable instead of $G77 to decide whether to include -O2,
10760 since $G77 is specific to Fortran 77.
10762 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
10764 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

10769 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10770 arguments so that it can be used with syntax identical to
10771 AC_PROG_F77, and so that we can more easily decide to
10772 remove/deprecate the DIALECT optional argument in the future if it
10773 proves troublesome.
10774 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10775 non-freeform-supporting compilers. Document freeform flags.
10777 2003-10-03 Akim Demaille <akim@epita.fr>
10779 * configure.ac: Look for emacs, not macs.
10780 Reported by Eric Sunshine.
10782 2003-10-03 Akim Demaille <akim@epita.fr>
10784 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10785 * bin/autoreconf.in (autoreconf_current_directory): Create the
10786 AUX_DIR if needed, for sake of automake --add-missing etc.
10787 Suggested by Alexandre Duret-Lutz.
10789 2003-10-03 Akim Demaille <akim@epita.fr>
10791 * configure.ac: Quotation and formatting changes.

10814 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
10816 2003-09-30 Akim Demaille <akim@epita.fr>
10818 * config/announce-gen (&print_news_deltas): Extracted from...
10819 (&print_changelog_deltas): here.
10820 (&news_file): Rename as...
10821 (@news_file): this.
10823 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
10825 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10826 have been created when invoking the compiler.
10827 * tests/fortran.at (GNU Fortran 77): Quote $G77.

10838 Problem reported by Lars J. Aas in
10839 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10840 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10841 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10842 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10844 2003-09-26 Akim Demaille <akim@epita.fr>
10846 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10847 directory for AC_CONFIG_COMMANDS' first argument exists.
10848 This makes valid the invocation of _AC_SRCPATH that follows.
10849 Reported by Eric Sunshine.
10850 * doc/autoconf.texi (Configuration Commands): Adjust.
10852 2003-09-26 Akim Demaille <akim@epita.fr>
10854 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10855 Reported by Ralf Corsepius.
10857 2003-09-26 Akim Demaille <akim@epita.fr>
10859 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10860 arguments.

10862 From Bruno Haible.
10864 2003-09-26 Paul Eggert <eggert@twinsun.com>
10866 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

10871 2003-09-26 Akim Demaille <akim@epita.fr>
10873 The test suite are sometimes assigning timings incorrectly.
10874 Reported by Henk Krus.
10875 Diagnosed by Nicolas Joly.
10877 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10878 AT_help_all.
10879 Instead of making AT_help a sequence of assignments to grow
10880 $at_help_all, just make AT_help_all be the growing contents of
10881 $at_help_all, and make a single assignment in...
10882 (AT_INIT): here.
10883 (at_times_skip): Flip the meaning and rename as...
10884 (at_times_p): this.
10885 (AT_INIT): When summarizing the test that ran, remove
10886 $at_times_file after use, and check it is present before trying to
10887 use it.
10889 2003-09-25 Akim Demaille <akim@epita.fr>
10891 Version 2.57d.
10893 * bin/Makefile.am (edit): Handle '@configure_input@'.
10894 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10895 (ifnames): chmod -w.
10896 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10897 executables, not bin/ executables! Otherwise all the magic needed
10898 to find non installed files is turned off. This caused a failure
10899 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10900 as found in its environment (sent by tests/autoreconf): pointing
10901 to bin/autom4te that could not find its files.
10902 * tests/mktests.sh: Force the replacement of generated files, for
10903 the sake of "mv" program that are interactive when overwriting a
10904 -w file.
10905 * config/install-sh: Upgrade from CVS Automake.
10907 2003-09-23 Paul Eggert <eggert@twinsun.com>

10912 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10913 Paul Eggert <eggert@twinsun.com>
10915 Trivial change to support GCC's configuration procedure.

10917 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10918 about inconsistency if the preprocessor is set to give errors for
10919 any warning.

10948 2003-09-10 Akim Demaille <akim@epita.fr>
10950 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10951 willing to edit the output files.
10953 2003-09-10 Akim Demaille <akim@epita.fr>
10955 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10956 and AC_FC_FREEFORM.
10957 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10958 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10960 2003-09-09 Akim Demaille <akim@epita.fr>

10973 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10974 Improve the accuracy of the wording about obsolescence.
10975 From a suggestion by Ian Lance Taylor in
10976 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10978 2003-09-05 Paul Eggert <eggert@twinsun.com>
10980 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10981 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10983 2003-09-04 Akim Demaille <akim@epita.fr>
10985 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10986 AC_FUNC_WAIT3.
10988 2003-09-04 Akim Demaille <akim@epita.fr>
10990 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10991 (freeze): When exiting, use $exit_code.
10992 * lib/autoconf/fortran.m4: Comment changes.
10994 2003-09-04 Akim Demaille <akim@epita.fr>
10996 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10998 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
11000 Add support for newer Fortran dialects. The F77 interface is
11001 unchanged, and continues to support Fortran 77. New FC macros
11002 correspond to all the old F77 macros, with output variables FC,
11003 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
11004 available dialect, but older dialects can be specified. There are
11005 new macros AC_FC_SRCEXT to set the source extension, and
11006 AC_FC_FREEFORM to accept free-form source files.
11008 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
11009 New macros.
11010 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
11011 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

11043 * tests/local.at: Require 2.57.
11044 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
11045 are defaulted by AT_CHECK anyway.
11046 Use AT_CHECK_AUTOM4TE.
11047 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
11048 missing dnl.

11096 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
11097 * configure.ac: Require Automake 1.7.6.
11099 2003-08-22 Akim Demaille <akim@epita.fr>
11101 Output stack traces in warnings.
11103 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
11104 Replace the former...
11105 (m4_warn): Pass the call stack to _m4_warn.
11106 * bin/autom4te.in: Adjust to output the call stack.
11107 * tests/m4sugar.at (m4@&t@_warn): Adjust.
11109 2003-08-22 Akim Demaille <akim@epita.fr>
11111 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
11112 * bin/autom4te.in: Adjust.
11114 2003-08-21 Akim Demaille <akim@epita.fr>
11116 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
11117 (&verbose): Remove.
11118 (&getopt): Adjust the note and verb channels, depending upon
11119 --verbose.
11120 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
11121 * bin/autoupdate.in: Adjust.
11122 Use &verb, not &verbose.
11124 2003-08-21 Akim Demaille <akim@epita.fr>
11126 * bin/autoheader.in (&parse_args): Use &parse_warnings and
11127 &parse_WARNINGS.
11128 ($help): Use Autom4te::ChannelDefs::usage.
11129 * bin/autoscan.in: Use Autom4te::ChannelDefs.
11130 * lib/Autom4te/General.pm: Don't export error: you don't own it.
11132 2003-08-21 Akim Demaille <akim@epita.fr>
11134 First stab at preserving warnings between calls to autom4te,
11135 including when the cache is used.
11137 There are still several issues: (i) there are too many runs of m4
11138 (one for include, one for warnings, and some more), (ii) warnings
11139 spreading on several lines are not handled gracefully, (iii) the
11140 code meant to have the call stack display for errors does not work
11141 (its handling should move from m4 to autom4te).
11143 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11144 Use them.
11145 (@preselect): Add m4_warn.
11146 ($exit_status): Remove, use $exit_code.
11147 ($help): Use Autom4te::ChannelDefs::usage.
11148 (&handle_m4): No longer define the m4_warnings.
11149 At each run, extract and report the warnings.
11150 Always cache the result, including if the exit status is on
11151 failure, since if nothing changes, we should result in the same
11152 failure, hence we can use the cache.
11153 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11154 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11155 Remove.
11156 (m4_warn): Redefine as a do-nothing: it is its invocation that
11157 matters, as warnings are now reported via traces.
11158 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11159 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11160 the latter reveals calls to the former.
11162 Adjust the tests.
11164 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
11166 2003-08-21 Akim Demaille <akim@epita.fr>
11168 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
11169 Use them.
11171 2003-08-21 Akim Demaille <akim@epita.fr>
11173 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
11174 forward order.
11175 * lib/Autom4te/ChannelDefs.pm: Doc typos.
11176 (&parse_warnings): Accept a list of warning requests.
11177 (&usage): Return a string, not a side effect.
11178 (cross): New warning category.
11180 2003-08-21 Akim Demaille <akim@epita.fr>
11182 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
11183 (&require_configure_ac): Accept an optional directory argument.
11184 ($configure_ac): Remove.
11185 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
11186 (&catfile): Remove.
11187 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
11188 * bin/autoscan.in: Adjust.
11190 2003-08-20 Akim Demaille <akim@epita.fr>
11192 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
11193 Reported by Alexandre Duret-Lutz.
11195 2003-08-20 Akim Demaille <akim@epita.fr>
11197 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11198 * bin/autom4te: Adjust.
11199 In particular, be Autoconf tools are really silent when properly
11200 working, bind the verbosity of the 'note' channel to $verbose.
11201 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11202 (&xsystem, &contents): Remove, since they are exported by...
11203 * lib/Autom4te/FileUtils.pm: this.
11204 More perldoc.
11205 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
11206 * lib/Autom4te/FileUtils.pm: here.
11208 2003-08-20 Akim Demaille <akim@epita.fr>
11210 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
11211 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
11212 from CVS Automake.
11214 2003-08-20 Akim Demaille <akim@epita.fr>
11216 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
11217 (autom4te-update): New.
11218 * Makefile.cfg (update): Bind autom4te-update.
11220 2003-08-19 Derek Price <derek@ximbiot.com>
11222 * lib/autotest/general.m4: Comment various HELP_* diversions.
11223 (PARSE_ARGS_BEGIN): New section for option parsing related
11224 initialization.

11226 package specific options and associated help.
11228 2003-08-19 Akim Demaille <akim@epita.fr>

11234 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
11236 * lib/autom4te.in (Automake-preselections): Preselect
11237 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
11238 and m4_sinclude.
11240 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
11242 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
11243 (Autoconf-without-aclocal-m4): ... this new language.
11244 * doc/autoconf.texi (autom4te Invocation): Mention
11245 Autoconf-without-aclocal-m4.
11247 2003-08-18 Derek Price <derek@ximbiot.com>
11249 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
11250 RUN-IF-PASS optional arguments.

11259 STDOUT & STDERR arguments.
11261 2003-08-14 Derek Price <derek@ximbiot.com>
11263 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
11264 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
11265 shorter column three. Add DESCRIPTION to log file content.
11267 2003-08-13 Derek Price <derek@ximbiot.com>
11269 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
11270 output.
11272 2003-08-12 Derek Price <derek@ximbiot.com>
11274 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
11275 (AT_CHECK_NOESCAPE): Move core functionality to...
11276 (_AT_CHECK): ...this new macro.
11278 2003-08-07 Derek Price <derek@ximbiot.com>
11280 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
11281 (AT_CHECK_NOESCAPE): ...to this new macro.
11283 2003-07-31 Paul Eggert <eggert@twinsun.com>
11285 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
11286 in Bash 2.01. Problem reported by Brian Gough in
11287 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
11289 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
11291 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
11292 -lcrt1.o, for OS X. (trivial change)
11294 2003-07-07 Paul Eggert <eggert@twinsun.com>
11296 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
11297 inside '#ifndef __cplusplus'. Problem reported by
11298 Bob Friesenhahn.
11300 2003-07-06 Bill Clarke <llib@computer.org>
11302 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
11303 'long', not 'int', for benefit of Sun's recent C++ compilers
11304 (trivial change). See:
11305 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
11306 (This really should be 'intptr_t', not 'long', but that would
11307 take more work.)
11309 2003-06-25 Akim Demaille <akim@epita.fr>
11311 * lib/Makefile.am (autom4te.cfg): Make it read only.
11312 Depend on Makefile since it contains substitutions.
11313 From Paolo Bonzini.
11314 * lib/autom4te.in (args): Add local.at? for Autotest args.
11315 This change was made on autom4te.cfg which is generated.
11316 Reported by Raja R. Harinath.
11318 2003-06-25 Akim Demaille <akim@epita.fr>
11320 * doc/autoconf.texi (Header Portability): sys/mount.h.
11321 From Gareth McCaughan.
11323 2003-06-23 Akim Demaille <akim@epita.fr>
11325 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11326 not all of them. This fixes 1. the fact that when testing
11327 Autoconf there are many many config.log, 2. the incorrect use of
11328 top_srcdir to find config.log.
11329 Don't mix the detailed output of failed test with the summary of
11330 failures. Rather, append detailed log afterwards.
11332 2003-06-23 Akim Demaille <akim@epita.fr>
11334 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11335 always run: output config.log on $at_group_log.
11337 2003-06-23 Akim Demaille <akim@epita.fr>
11339 * tests/torture.at (#define header templates): Don't use quotes in
11340 C++ comments as it puzzles Emacs' sh font-lock-mode.
11342 2003-06-23 Akim Demaille <akim@epita.fr>
11344 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
11345 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
11346 * tests/atspecific.m4: Rename as...
11347 * tests/local.at: This.
11348 * tests/suite.at: Move the globals into...
11349 * tests/local.at: here.
11350 * tests/Makefile.am: Adjust.
11351 * doc/autoconf.texi (testsuite Scripts): Adjust.
11353 2003-06-21 Kevin Ryde <user42@zip.com.au>
11355 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
11356 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
11357 ensuring we add -std1 for full-ANSI.
11359 * doc/autoconf.texi (hdrindex): New macro.
11360 Add index entries for portability of various standard header files.
11362 2003-06-20 Akim Demaille <akim@epita.fr>
11364 * configure.ac: Bump to 2.57b.
11366 2003-06-20 Akim Demaille <akim@epita.fr>
11368 Version 2.57a.
11370 2003-06-20 Akim Demaille <akim@epita.fr>
11372 * bin/autom4te.in: Don't rely on $HOME being defined.
11373 Reported by Marc Espie as PR/233.
11375 2003-06-20 Akim Demaille <akim@epita.fr>
11377 * lib/autotest/general.m4: Use at_times_file only if used.
11378 From Nicolas Joly.
11380 2003-06-20 Akim Demaille <akim@epita.fr>
11382 * config/config.guess, config/config.sub, config/elisp-comp,
11383 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
11384 Update from masters.
11386 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
11388 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
11389 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
11390 (TEST_SCRIPT): New diversion.
11391 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
11392 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11393 (AT_INIT): Support for expected failures.
11395 2003-06-02 Akim Demaille <akim@epita.fr>
11397 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
11398 changes.
11399 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
11400 Autoconf nor Automake.
11401 (&contents): New, from Automake.
11402 PODify.
11404 2003-05-28 Paul Eggert <eggert@twinsun.com>
11406 * NEWS, doc/autoconf.texi (Particular Functions),
11407 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11408 is the inverse of localtime.
11410 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
11412 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11413 (handle_exec_errors): New function. Work around $! being
11414 altered by WEXITSTATUS.
11415 (xqx, xsystem): Use handle_exec_errors.
11417 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11419 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11420 Do not call `_exit()', simply modify `$?'.
11421 (xsystem): Reset $! before running system, and check it afterward.
11422 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11423 63 for version mismatches.
11425 2003-05-23 Akim Demaille <akim@epita.fr>
11427 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11428 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11429 the middle of a line).
11430 * lib/m4sugar/m4sugar.m4: Likewise.
11431 Remove useless spaces in comments.
11433 2003-05-23 Akim Demaille <akim@epita.fr>
11435 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11436 exit 63, so that we (or Automake's "missing") can tell the
11437 difference with a plain failure.
11438 * doc/autoconf.texi (Notices): Adjust.
11440 2003-05-23 Akim Demaille <akim@epita.fr>
11442 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11443 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
11444 White spaces cleanup.
11446 2003-05-22 Jim Meyering <jim@meyering.net>
11447 Paul Eggert <eggert@twinsun.com>
11449 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11450 Remove `#include <stdlib.h>' from the list; we should never
11451 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11452 resulting namespace pollution would cause other tests to fail.
11453 Configure scripts run with some older versions of g++ and HP's
11454 aCC would fail due to such an #include. Problems reported by
11455 Matthew Mueller in <http://bugs.debian.org/120704> and by
11456 Keith Bostic in
11457 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11458 In the test, use the test declaration before including <stdlib.h>,
11459 as that's closer to how it'll be used.
11461 2003-05-23 Akim Demaille <akim@epita.fr>
11463 * doc/autoconf.texi (Header Portability): ucred.h.
11464 From Ian Redfern.
11466 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11468 Overhaul Autotest's logging: generate separate log files
11469 in testsuite.dir/NNN/testsuite.log, and append them to
11470 testsuite.log instead of re-running the test verbosely.
11472 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11473 file descriptor, write 0 to at_status_file instead of setting
11474 at_status=0, initialize some new variables (at_status_file,
11475 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11476 to rerun the tests, instead append the at_group_log to the
11477 at_suite_log when a test fails.
11478 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11479 with the AS_MESSAGE_LOG_FD redirected to stdout.
11480 (AT_CLEANUP): save the output status in $at_status_file
11481 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11482 its original place.
11483 (AT_CHECK): since tests are run with a redirected stdout,
11484 and used to be re-run in verbose mode, turn some $at_verbose
11485 into echo, and don't redirect the output of testing stdout
11486 and stderr.
11488 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11489 the name of the debugging directory and information about
11490 its contents.

11609 2003-05-06 Akim Demaille <akim@epita.fr>
11611 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11612 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11613 by aclocal.m4 is changed it might require the importing of another
11614 m4 extension file, i.e., aclocal must be run.
11616 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11617 (&parse_args): Use --force with aclocal if required and supported.

11631 2003-04-29 Derek Price <derek@ximbiot.com>
11633 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11634 seperator with m4_append_uniq(). It doesn't work.
11635 (AT_CLEANUP): Add `;' to end of at_help_all.
11636 (AT_INIT): Allow --keywords to be specified more than once. When
11637 grepping $at_help_all for keywords, use the field and keyword
11638 seperators to ensure a complete keyword match. Alter at_prev handling
11639 to support the new --keywords behavior.
11641 2003-04-27 Karl Berry <karl@freefriends.org>
11643 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11644 align better with others. I also made some of the individual

11691 2003-03-31 Derek Price <derek@ximbiot.com>

11717 * tests/torture.at (Configuring subdirectories): Require aclocal
11718 1.4, otherwise the test fails, as it does support configure.ac.

11846 2003-02-20 Akim Demaille <akim@epita.fr>
11848 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

11866 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11867 innocuous variant befor including <limits.h> or <assert.h>. This
11868 works around a bug reported by Albert Chin: HP-UX 11i
11869 (and earlier versions) have a <limits.h> that declares
11870 gettimeofday and many other functions.
11872 2002-12-03 Paul Eggert <eggert@twinsun.com>

11881 nontrivially in main's body, so that f's external declaration is
11882 not optimized away in AIX. This should fix the bug reported by
11883 Martin Frydl in
11884 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11886 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11887 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11888 defined, to support freestanding compilers. This should fix the
11889 bug reported by Momchil Velkov in
11890 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11892 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11893 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11894 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11895 by Simon Josefsson in
11896 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11898 * Makefile.maint (www-gnu): New macro.

11924 Update from masters.
11926 2002-11-14 Akim Demaille <akim@epita.fr>
11928 * Makefile.maint: Sync with Bison, i.e.:
11929 (po-check): Scan .l and .y files instead of the
11930 .c and the .h files that they generate. This fixes the bug
11931 reported by Tim Van Holder in:
11932 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11933 Look for N_ as well as for _. Try to avoid matching #define for
11934 N_ and _.
11935 From Paul Eggert.

11950 than assigning in main, to avoid HP cc +O3 optimizing it away.

11992 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11993 Remove.
11994 We _have_ to stop using the old compatibility scheme that tried to
11995 avoid useless backslashes because Libtool 1.4.3 contains a
11996 AC_DEFINE([error_t], [int],
11997 [Define to a type to use for \`error_t' if it is not
11998 otherwise available.])
11999 We _have_ to quote the single quote and backslashes with \. The
12000 old compatibility scheme saw that ` was backslashed, and therefore
12001 did not quote the single quote. Hence before this patch, Autoconf
12002 was not compatible with Libtool.
12004 2002-11-04 Paul Eggert <eggert@twinsun.com>

12048 Make variable, not a shell variable.
12049 Suggested by Bruno Haible.
12051 2002-10-31 Akim Demaille <akim@epita.fr>

12076 Problem reported by Bruno Haible.
12078 2002-10-29 Akim Demaille <akim@epita.fr>

12414 format, so that Emacs' compile mode understands us.
12415 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12416 if some file was changed instead of `print'.
12417 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
12418 (&parse_args): Remove the dead options.
12419 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
12420 autoheader's quiet mode.
12421 (AT_CHECK_AUTOUPDATE): Likewise.
12422 * tests/tools.at (autoupdate): Adjust.
12423 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12425 2002-10-11 Akim Demaille <akim@epita.fr>
12427 No longer use CPP to check for the existing of headers: use CC to
12428 check for compilability.
12430 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
12431 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
12432 (_AC_CHECK_HEADER_NEW): Rename as...
12433 (AC_CHECK_HEADER): this.
12435 * lib/autotest/general.m4 (AT_INIT): Include the failed test
12436 numbers in the Subject suggestion.
12438 2002-10-11 Akim Demaille <akim@epita.fr>
12440 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
12441 Suggest using AC_CHECK_DECLS instead.
12443 2002-10-11 Akim Demaille <akim@epita.fr>
12445 * tests/torture.at (AC_ARG_VAR): Have configure report the value
12446 of `precious'.
12448 2002-10-11 Akim Demaille <akim@epita.fr>
12450 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
12451 file name to enable parallel executions.
12452 From Sam Varshavchik.
12454 2002-10-08 Akim Demaille <akim@epita.fr>
12456 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12457 aclocal invocation, as Gettext macros might not be visible to
12458 aclocal.
12459 Instead of blindly running autopoint, scan configure.ac (not the
12460 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12461 Reported by Paul D. Smith.
12463 2002-10-08 Paul Eggert <eggert@twinsun.com>
12465 Work around problems found when POSIXLY_CORRECT=1 is set.
12466 None of this seems to have anything to do with POSIX, really,
12467 but it's how Perl getopt works.
12468 * bin/autom4te.in (parse_args): Configure GetOpt with
12469 "permute", too.
12470 * doc/autoconf.texi (Invoking autom4te):
12471 --warning -> --warnings.
12472 * lib/autom4te.in: --warning -> --warnings.
12474 2002-09-28 Akim Demaille <akim@epita.fr>
12476 * doc/autoconf.texi (autom4te.cache): New section.
12478 2002-09-28 Akim Demaille <akim@epita.fr>
12480 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
12481 (Automake-preselections): Update.
12482 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
12484 2002-09-28 Akim Demaille <akim@epita.fr>
12486 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
12487 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
12488 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12489 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12491 2002-09-28 Akim Demaille <akim@epita.fr>
12493 * tests/torture.at (Configuring subdirectories): Be robust to
12494 users who use config.site to require for a cache: in this case,
12495 the two last configure runs, using two different sets of
12496 arguments, trigger a legitimate error.
12498 2002-09-28 Akim Demaille <akim@epita.fr>
12500 * tests/m4sh.at (Functions Support, Functions and return Support):
12501 New.
12503 2002-09-28 Akim Demaille <akim@epita.fr>
12505 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12506 autoheader are Perl programs.
12507 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12508 (autom4te): Specify that the sources are in the $srcdir.
12509 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12511 2002-09-28 Akim Demaille <akim@epita.fr>
12513 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
12514 (tm_zone): Move their rules to...
12515 * lib/autoconf/types.m4: here, using AN_ macros.
12516 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12517 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12518 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
12519 * lib/autoconf/programs.m4: here.
12520 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
12521 (ETAGS_FOR_AUTOCONF): New.
12522 Use it.
12524 2002-09-28 Akim Demaille <akim@epita.fr>
12526 * lib/autoconf/autoscan.m4: New file.
12527 * lib/autoconf/autoconf.m4: Include it.
12528 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12529 that were listed in the original autoscan.list.
12530 * lib/autoconf/headers.m4: Similarly with headers.
12531 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12532 (.m4.m4f): Don't pass --prepend-include, since that's done by
12533 tests/autom4te itself.
12534 * lib/autoscan/Makefile.am: Include freeze.mk.
12535 (autoscan.list): New target --this file is no longer a source.
12536 (autoscan.pre): New file.
12538 2002-09-28 Akim Demaille <akim@epita.fr>
12540 * bin/autoscan.in (@kinds): Make them singular.
12541 Adjust all uses.
12542 (&init_tables): When --debug, report the list of rules to ease
12543 tracking changes in autoscan.list.
12544 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12546 2002-09-28 Akim Demaille <akim@epita.fr>
12548 * lib/autoscan/functions, lib/autoscan/headers,
12549 * lib/autoscan/identifiers, lib/autoscan/makevars,
12550 * lib/autoscan/programs: Merge into...
12551 * lib/autoscan/autoscan.list: this.
12552 * bin/autoscan.in (&init_tables): Adjust.
12554 2002-09-28 Akim Demaille <akim@epita.fr>
12556 * lib/autoscan/functions, lib/autoscan/headers,
12557 * lib/autoscan/identifiers, lib/autoscan/makevars,
12558 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12559 `functions' line is now prefixed with `function:'.
12560 * bin/autoscan.in (&init_tables): Adjust.
12562 2002-09-28 Akim Demaille <akim@epita.fr>
12564 From now on, autoscan files must always map a macro name to a
12565 word: there is no `default' macro for autoscan.
12567 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12568 all.
12569 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12570 explicit.
12572 2002-09-28 Akim Demaille <akim@epita.fr>
12574 * bin/autoscan.in (%c_keywords): Remove.
12575 (&used): Keep only track of the words we might be interested in.
12576 (&output_kind): It is no longer needed to look for non active
12577 checks.
12579 2002-09-27 Akim Demaille <akim@epita.fr>
12581 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12582 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12583 * lib/autoscan/functions: Adjust.
12584 * doc/autoconf.texi (Particular Functions): Adjust.
12586 2002-09-27 Akim Demaille <akim@epita.fr>
12588 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
12589 from /tmp.
12590 Thanks to Bill Moseley and Paul Eggert.
12591 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12592 the tmpdir must be created.
12593 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12594 dir be in the build tree, instead of $TMPDIR.
12596 2002-09-27 Akim Demaille <akim@epita.fr>
12598 * bin/autoscan.in: Improve the comments.
12599 (&parse_args): Drop obsolete undocumented options.
12600 (&output_kind): Output warnings.
12601 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
12602 (getwd): Trigger a warning.
12604 2002-09-26 Akim Demaille <akim@epita.fr>
12606 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12607 Reported by Ralf Corsepius.
12608 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12610 2002-09-26 Akim Demaille <akim@epita.fr>
12612 Single suffix rules and seperated dependencies are not portable.
12614 * doc/autoconf.texi (Installation Directory Variables): Update.
12615 (Limitations of Make): Some about `Single Suffix Rules and
12616 Separated Dependencies'.
12617 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12618 (ifnames, autoscan, autom4te): Un-factor into several rules.
12620 2002-09-25 Paul Eggert <eggert@twinsun.com>
12622 * BUGS (Interoperability bugs): New section. Mention libtool
12623 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12625 2002-09-24 Paul Eggert <eggert@twinsun.com>
12627 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12628 make handles suffix-rules differently from GNU make.
12630 * bin/Makefile.am (SUFFIXES, .in): Remove.
12631 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12632 Move the body of the old .in rule here.
12634 2002-09-16 Akim Demaille <akim@epita.fr>
12636 i960 compilers create `b.out' files by default.
12637 Reported by Ralf Corsepius.
12639 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12640 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12642 2002-09-13 Paul Eggert <eggert@twinsun.com>
12644 * doc/autoconf.texi (Particular Headers): Remove obsolete
12645 reference to `struct timezone' in the description of
12646 AC_HEADER_TIME.
12648 2002-09-13 Akim Demaille <akim@epita.fr>
12650 Version 2.54.
12652 * config/config.sub, config/config.guess: Update.
12653 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12654 * Makefile.am: Adjust.
12656 2002-09-13 Akim Demaille <akim@epita.fr>
12658 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12659 reading config.log when the compiler is rejected.
12660 Suggested by Guido Draheim.
12662 2002-09-13 Akim Demaille <akim@epita.fr>
12664 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12665 (chdir_init) might hang when stat'ing mounted directories.
12666 Reported by Vance Shipley.
12668 2002-09-12 Akim Demaille <akim@epita.fr>
12670 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12671 the lists.
12673 2002-09-12 Akim Demaille <akim@epita.fr>
12675 * doc/autoconf.texi (Defining Symbols): Present two different
12676 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12677 difference between 1 argument calls, and 2-3 argument calls.
12679 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12681 * doc/autoconf.texi: Review grammar and punctuation.
12683 2002-09-11 Paul Eggert <eggert@twinsun.com>
12685 * doc/autoconf.texi: Fix minor formatting, spelling, and
12686 grammatical typos.
12687 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12688 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12689 is obsolescent.
12691 2002-09-11 Akim Demaille <akim@epita.fr>
12693 * doc/autoconf.texi (Questions): Rename as...
12694 (FAQ): this.
12695 (Defining Directories): New.
12697 2002-09-09 Akim Demaille <akim@epita.fr>
12699 * doc/autoconf.texi (Making testsuite Scripts): Update.
12700 Suggested by Nishio Futoshi.
12702 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12704 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12705 plain `@' is wanted.
12707 2002-09-09 Akim Demaille <akim@epita.fr>
12709 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12710 `duplicates', since the algorithm was too naive and could keep
12711 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12712 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12713 Reported by Ralf Corsepius.
12714 * tests/torture.at (Configuring subdirectories): Exercise these
12715 cases.
12717 2002-09-09 Akim Demaille <akim@epita.fr>
12719 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12720 looking for a replacement file.
12721 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12722 directory is relative.
12723 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12724 directory definition.
12725 Reported by Andreas Schwab and Jim Meyering.
12727 2002-09-06 Akim Demaille <akim@epita.fr>
12729 * doc/autoconf.texi (Setting Output Variables): Clarify what
12730 precious variables are.
12731 Suggested by Pontus Skoeld.
12733 2002-09-05 Akim Demaille <akim@epita.fr>
12735 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12736 (ifnames, autoscan, autom4te): Since we don't only depend on
12737 configure.ac variables (such as VERSION etc.), but also on prefix
12738 and so forth, depend on Makefile, not configure.ac.
12739 Reported by Alexandre Duret-Lutz.
12740 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12742 2002-09-05 Kevin Ryde <user42@zip.com.au>
12744 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12745 doesn't seem to be confined to ia64, just say "some versions".
12747 2002-09-04 Akim Demaille <akim@epita.fr>
12749 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12750 Automake 1.6c.
12751 * Makefile.am (maintainer-clean-local): Remove.
12752 (MAINTAINERCLEANFILES): Remove COPYING.
12754 2002-09-03 Paul Eggert <eggert@twinsun.com>
12756 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12757 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12758 Brinkmann.
12760 2002-09-03 Akim Demaille <akim@epita.fr>
12762 * configure.ac: Bump to 2.53d.
12763 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12764 as of today, on Automake's team suggestion.
12766 2002-09-03 Akim Demaille <akim@epita.fr>
12768 Version 2.53c.
12770 2002-09-02 Akim Demaille <akim@epita.fr>
12772 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12773 SITE_MACRO_DIR.
12774 * configure.ac: Disable SITE_MACRO_DIR.
12776 2002-09-02 Jim Meyering <meyering@lucent.com>
12778 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12779 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12780 Also, tweak grammar: s/make sure to/be sure to/.
12782 2002-09-02 Paul Eggert <eggert@twinsun.com>
12784 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12785 directory names are generally preferable to physical names.
12787 2002-09-02 Akim Demaille <akim@epita.fr>
12789 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12790 Reported by Raja R. Harinath.
12791 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12792 * bin/autoupdate.in: Use error instead of die.
12794 2002-09-01 Paul Eggert <eggert@twinsun.com>
12796 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12797 ordinary shell concatenation rather than echo+tr+sed command that
12798 runs afoul of a long-line-related sed bug in Solaris 8.
12800 * bin/autoheader.in (parse_args): --warning -> --warnings.
12802 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12803 stdout, as traditional "ls" does.
12804 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12805 _AC_COMPILER_EXEEXT_O): Likewise.
12806 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12808 * bin/autoconf.as: Add --prepend-include option. This patch was
12809 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12810 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12812 * bin/autoconf.in, configure: Regenerate.
12814 * doc/autoconf.texi (Special Shell Variables): Mention
12815 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12817 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12818 MAILPATH and set PS1, PS2, PS4 to default values, to work
12819 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12820 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12821 the Autoconf documentation specifies; fall back to "unset" only if
12822 this fails. Use a shell for-loop for this rather than an m4 loop,
12823 to shorten the output script.
12825 2002-08-30 Paul Eggert <eggert@twinsun.com>
12827 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12828 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12829 for the CDPATH problem. Document PWD.
12830 (Limitations of Builtins): Document the problem that "cd $foo" and
12831 "ls $foo" may refer to different directories in shells conforming
12832 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12833 example, since the old example is now out of date.
12835 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12836 FOO" and "ls FOO" talk about different directories; this catches
12837 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12838 spaghetti.
12840 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12841 of rolling our own unset.
12842 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12843 in practice we needn't worry about CDPATH if unset doesn't work.
12845 * Makefile.in, aclocal.m4, bin/Makefile.in,
12846 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12847 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12848 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12849 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12850 tests/Makefile.in: Regenerate with Automake 1.6.3.
12852 * config/config.guess, config/config.sub, config/mkinstalldirs:
12853 Update.
12855 * configure: Regenerate with self.
12857 2002-08-30 Kevin Ryde <user42@zip.com.au>
12859 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12860 default output.
12862 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12864 * bin/autom4te.in (Request::load): Correctly test for "do" read
12865 failure.
12867 2002-08-29 Akim Demaille <akim@epita.fr>
12869 * lib/Autom4te/General.pm (&xqx): New.
12870 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12871 hand, which is not portable.
12872 (&error): New.
12873 * bin/autom4te.in: Use them.
12874 Use &error instead of die.
12875 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12876 Adjust.
12878 2002-08-17 Paul Eggert <eggert@twinsun.com>
12880 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12881 default list of compilers to try, since it was long ago superseded
12882 by the ksh fc builtin. Suggested by Steven G. Johnson.
12884 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12886 * doc/autoconf.texi (Invoking autom4te): End the option table,
12887 fixing a bug introduced by the previous patch.
12888 (Limitations of Make): Add a 'target lookup' subentry in the
12889 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12891 2002-07-29 Mark D. Roth <roth@feep.net>
12893 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12894 options and use $AUTOM4TE_PATH.

12905 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12906 Replace with:
12907 (AM_MAKEINFOFLAGS): New macro.
12908 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12909 * Makefile.am (INSTALL): Use the new macros.
12910 Use -o rather than --output, since "missing" does not grok --output.
12912 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12914 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12915 comments do not always work. Never trust the exit status of
12916 `make -k'.
12918 2002-07-24 Kevin Ryde <user42@zip.com.au>
12920 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12921 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

12925 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12926 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12927 apparently treats PATH="nonexistent" as if it contained ".".
12928 Bug reported by Stefan `Sec' Zehl.
12930 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12932 * doc/autoconf.texi (Limitations of Make): Mention the special

13045 * doc/autoconf.texi: Use @enddots{} or @dots{} where appropriate.
13047 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
13049 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
13050 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,

13052 so that Emacs setups GNU style for perl-mode and cperl-mode.
13054 2002-06-27 Paul Eggert <eggert@twinsun.com>
13056 * config/install-sh: Quote $src. Prefer || to test's -o option,
13057 as per "Limitations of Builtins".
13058 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
13059 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
13061 * tests/mktests.sh: Use grep instead of fgrep, as per
13062 "Limitations of Builtins".
13064 2002-06-15 Paul Eggert <eggert@twinsun.com>
13066 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
13067 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
13068 so that we consistently test the just-built programs.
13069 * tests/wrappl.as: Likewise.
13071 2002-06-12 Paul Eggert <eggert@twinsun.com>
13073 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

13077 * bin/autoreconf.in (autoconf, autoheader): Likewise.
13078 * bin/autoscan.in (autom4te): Likewise.
13079 * bin/autoupdate.in (autom4te): Likewise.
13081 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for

13083 on Solaris 2.5.1.
13085 2002-06-11 Andreas Schwab <schwab@suse.de>
13087 * doc/autoconf.texi: Add more dir entries.
13089 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
13091 * bin/autom4te.in ($cache): Don't define using `$me', the name
13092 of the cache should not depend on the name under which autom4te
13093 was installed.
13095 2002-06-07 Akim Demaille <akim@epita.fr>
13097 * tests/tools.at (autoconf: forbidden tokens, basic)

13109 rename as...
13110 (AC_REPLACE_FNMATCH): this.
13111 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
13112 AC_FUNC_FNMATCH_GNU.
13114 2002-06-07 Akim Demaille <akim@epita.fr>
13116 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the

13119 2002-06-07 Akim Demaille <akim@epita.fr>
13121 * bin/autom4te.in (warn_forbidden): When rejecting a token,
13122 suggest m4_pattern_allow.
13123 Suggested by Adam J. Richter.
13125 2002-06-07 Akim Demaille <akim@epita.fr>
13127 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
13128 ac_config_libobj_dir.
13129 (AC_CONFIG_LIBOBJ_DIR): New.
13130 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
13131 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
13132 Use ac_config_libobj_dir to find the replacement files.
13133 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
13134 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
13135 (AC_REPLACE_FNMATCH_GNU): these.
13136 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
13137 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
13138 * tests/mktests.sh (ac_exclude_list): Don't check

13141 2002-06-06 Paul Eggert <eggert@twinsun.com>
13143 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
13144 if ln doesn't work.
13145 * NEWS: Likewise.
13146 * doc/autoconf.texi (Configuration Links): Likewise.

13149 2002-06-05 Paul Eggert <eggert@twinsun.com>
13151 * config/config.guess, config/config.sub, config/texinfo.tex:
13152 Update from masters.
13154 2002-05-29 Paul Eggert <eggert@twinsun.com>
13156 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
13157 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.

13177 * NEWS, doc/autoconf.texi (Particular Types): Document it.
13178 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
13179 instead of AC_MBSTATE_T, which never existed.
13181 2002-05-23 Akim Demaille <akim@epita.fr>
13183 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
13184 version of Autoconf that is discussed.
13186 2002-05-22 Paul Eggert <eggert@twinsun.com>
13188 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
13189 from the default list of compilers to try. Suggested by
13190 Kate Hedstrom.
13191 * NEWS: Document the above.
13192 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
13194 2002-05-17 Paul Eggert <eggert@twinsun.com>
13196 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
13197 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
13198 This improves on an earlier suggestion by H. Peter Anvin.
13200 2002-05-16 Paul Eggert <eggert@twinsun.com>
13202 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13203 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13204 Both macros now accept an optional source-dir arg.
13205 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13207 * NEWS: Document this.
13208 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13210 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13211 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13212 not for GNU extensions; this undoes part of the 2000-11-03 change,
13213 reverting to 2.13-compatible behavior.
13214 Add new optional argument DIR.
13215 (AC_FUNC_FNMATCH_GNU): New macro.
13217 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
13219 2002-05-08 Paul Eggert <eggert@twinsun.com>
13221 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13222 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13223 and it causes a 'test' syntax error if it fails.
13224 Bug reported by Stephen Gildea.
13226 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13227 If prototypes are supported, use them to check this at compile-time,
13228 instead of trying to check it at run-time. If we must do a run-time
13229 check, assume that setvbuf is standard when cross-compiling, as
13230 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13231 Bug reported by Paul D. Smith.
13233 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13234 argument specifying location of getloadavg.c. This removes a
13235 FIXME. This idea was taken from Jim Meyering's implementation in
13236 textutils.
13237 * doc/autoconf.texi (Particular Functions): Document this.
13238 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13239 that's what the code does; this fixes a bug reported by
13240 Paul D. Smith.
13242 2002-05-03 Akim Demaille <akim@epita.fr>
13244 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13245 autopoint instead of gettextize.
13246 ($uses_alocal): Rename as...
13247 ($uses_aclocal): this.
13248 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13249 Suggested by Bruno Haible.
13251 2002-05-03 Akim Demaille <akim@epita.fr>
13253 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13255 2002-04-29 Paul Eggert <eggert@twinsun.com>
13257 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13258 files to be 1 second older; just set them to be the same time.
13259 Also, sleep 1 second after the first aclocal, to work around
13260 problems with sub-second time stamps on the input files.
13262 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13264 * doc/autoconf.texi: Mention "set -e -x" lossage
13265 under node "Limitations of Builtins".
13267 2002-04-29 Akim Demaille <akim@epita.fr>
13269 * doc/install.texi: Better wording for setting variables when
13270 running configure.
13271 From Christian Cornelssen.
13273 2002-04-29 Akim Demaille <akim@epita.fr>
13275 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13276 of lack of $LINENO support, then the test will compare the $LINENO
13277 in testsuite vs. the lineno in the test file. This is wrong, of
13278 course.
13279 Be sure to protect it.
13280 Reported by Patrick Welche.
13282 2002-04-25 Akim Demaille <akim@epita.fr>
13284 * doc/autoconf.texi (Obsolete Macros): Typo.
13285 Reported by Vladimir Volovich.
13287 2002-04-25 Akim Demaille <akim@epita.fr>
13289 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13290 than some of the input files, hence, on the second run of aclocal,
13291 if some of its input are younger, make them older.
13292 Suggested by Paul Eggert.
13294 2002-04-25 Akim Demaille <akim@epita.fr>
13296 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
13297 Thanks to Paul Eggert.
13299 2002-04-25 Akim Demaille <akim@epita.fr>
13301 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
13302 and ac_subst_vars be sh variables containing the list of
13303 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13304 DEFAULT diversion.
13305 (_AC_INIT_PREPARE): Use them to log them.
13306 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13307 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13308 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13309 _AC_SUBST_FILES and _AC_SUBST_VARS.
13310 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13312 2002-04-24 Akim Demaille <akim@epita.fr>
13314 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13315 autoheader, so that automake does not complain about a missing
13316 config.h.in that was to be created.
13318 2002-04-23 Akim Demaille <akim@epita.fr>
13320 * bin/autoheader.in (parse_args): --warning takes an argument.
13321 Fixes PR/220.
13323 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
13325 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

13339 comma.
13340 Reported by Gregory Giannoni.
13342 2002-04-22 Akim Demaille <akim@epita.fr>
13344 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
13345 Fixes false failures on Darwin.
13347 2002-04-21 Paul Eggert <eggert@twinsun.com>

13354 2002-04-20 Paul Eggert <eggert@twinsun.com>
13356 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
13357 ZSH_VERSION fixes. Bug reported by Raja R Harinath.
13358 * lib/autotest/general.m4 (AT_INIT): Likewise.

13370 Minor spelling and grammar fixes.
13372 * doc/autoconf.texi: Follow the outline suggested in the GNU
13373 Sample Texts sections of the Texinfo 4.2 manual. Most
13374 importantly, this makes sure that the copyright notices appear in
13375 all output formats. You probably need Texinfo 4.2 to generate
13376 the manual now.
13378 Fix some bugs when using "$@" when there might be zero positional
13379 arguments in cases where this matters.
13381 * bin/autoconf.as: Rewrite so that the problem does not come up.

13397 * tests/atgeneral.m4 (AT_INIT): Likewise.
13399 * tests/c.at: We can't have zero arguments, so remove workaround
13400 that is not portable to Zsh.
13402 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
13404 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

13411 2002-04-10 Akim Demaille <akim@epita.fr>
13413 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
13414 workaround for ${1+"$@"}.
13415 * doc/autoconf.texi (Shell Substitutions): Explain it.
13416 From Oliver Kiddle and Peter Stephenson.
13418 Have M4sh perform minimal shell sanitizing.
13420 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13421 part into...
13422 (_AS_PREPARE): this new macro.
13423 (AS_PREPARE): New.
13424 (AS_INIT): Invoke AS_SHELL_SANITIZE.
13425 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
13427 Adjust Autoconf and Autotest.
13429 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
13430 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
13431 * lib/autotest/general.m4 (AT_INIT): Likewise.
13432 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
13433 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
13434 AS_SHELL_SANITIZE.
13436 Use this M4sh to generate Autoconf's shell scripts.
13438 * tests/wrapsh.as: New, precursor of wrapsh.in.
13439 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13440 on Autotest and M4sh.
13441 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13442 (wrapsh.in): New target.
13443 * bin/autoconf.as: New, precursor of autoconf.in.
13444 (autoconf.in): New target.
13446 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

13449 with indented comments in rules.
13451 2002-04-09 Andreas Schwab <schwab@suse.de>
13453 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
13454 ac_top_builddir when setting ac_abs_top_builddir.
13456 2002-04-06 Kevin Ryde <user42@zip.com.au>
13458 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
13459 (Portable Shell): Cross reference to Systemology.
13461 2002-04-05 Akim Demaille <akim@epita.fr>
13463 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
13464 directories when descending in a SUBDIRS.
13465 Reported by Ezra Peisach.
13467 2002-04-04 Andreas Schwab <schwab@suse.de>
13469 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13470 contains no literal separators.
13472 2002-04-03 Akim Demaille <akim@epita.fr>
13474 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13475 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13476 Use dnl, not the KILL diversion.
13477 Extracted from...
13478 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13479 (AC_CONFIG_LINKS): here.
13480 Adjust.
13481 Don't use the KILL diversion, as it kills spurious output, which
13482 results in failures being hidden.
13483 Use m4_defn where appropriate.
13484 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13485 after the second argument.
13486 Use m4_defn.
13487 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13488 syntax, as it is provided by M4sugar.
13489 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13491 2002-04-03 Andreas Schwab <schwab@suse.de>
13493 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
13494 expanded if $# <= 2.
13496 * bin/autoreconf.in (autoreconf): Run automake after rerunning
13497 aclocal.
13499 2002-04-03 Akim Demaille <akim@epita.fr>

13502 (_AC_COMPILER_EXEEXT_REJECT): New.
13503 Also recognize *.bb and *.bbg as compilation byproducts.
13504 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
13505 (_AC_COMPILER_OBJEXT): Use them.
13506 Fixes Debian #138666.
13508 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13510 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13512 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13513 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13514 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13515 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13516 (AC_C_CONST): Same.
13517 (AC_C_INLINE): Same.
13518 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
13519 * doc/autoconf.texi, NEWS: Document.
13520 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
13521 AC_C_CROSS.

13526 _AS_MKDIR_P_PREPARE.
13528 2002-03-28 Kevin Ryde <user42@zip.com.au>
13530 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13531 to avoid versions of HP C which don't allow that.
13533 2002-03-27 Paul Eggert <eggert@twinsun.com>
13535 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13536 (AS_SHELL_SANITIZE): Invoke it.
13537 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
13539 2002-03-26 Akim Demaille <akim@epita.fr>
13541 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13543 2002-03-26 Akim Demaille <akim@epita.fr>
13545 * doc/autoconf.texi (Introduction): The GNATS base moved.
13547 2002-03-25 Paul Eggert <eggert@twinsun.com>
13549 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13550 as POSIX requires, as it doesn't work with Zsh.
13551 * doc/autoconf.texi (Assignments): Document the problem.
13553 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13555 * doc/autoconf.texi (Limitations of Make): Mention more issue
13556 about VPATH, overriding of macros in sub-makes, and handling of
13557 SHELL.
13559 2002-03-21 Paul Eggert <eggert@twinsun.com>
13561 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13562 problem with here-document buffer boundaries.
13564 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13565 when reinvoking the shell, to work around problems with installers
13566 who put strange things like "cd" commands in their environments.
13568 2002-03-19 Akim Demaille <akim@epita.fr>
13570 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13571 From Aaron Ucko.
13573 2002-03-19 Akim Demaille <akim@epita.fr>
13575 * bin/autoscan.in (scan_file): Specify the location in `&used'
13576 invocations.
13577 From Nicolas Joly.
13579 2002-03-19 Akim Demaille <akim@epita.fr>
13581 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13582 From Nishio Futoshi.
13584 2002-03-19 Akim Demaille <akim@epita.fr>
13586 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
13588 2002-03-18 Paul Eggert <eggert@twinsun.com>
13590 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13591 (Limitations of Usual Tools): Add mkdir section.
13593 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13594 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13595 back on AS_DIRNAME to compute prefixes otherwise; this is
13596 roughly what mkinstalldirs does. That way, we need not have
13597 our own filename disassembler. The old disassembler did not
13598 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13600 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13601 Create at_test_all by a series of assignments,
13602 not by a single assignment of a long string. The latter causes ksh
13603 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13604 presumably because of a buffer overrun.
13606 2002-03-14 Paul Eggert <eggert@twinsun.com>
13608 * lib/autotest/general.m4 (at_times_skip):
13609 Renamed from at_times. Now a boolean.
13610 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13611 says 'times: not found'.
13613 2002-03-14 Akim Demaille <akim@epita.fr>
13615 * bin/autoreconf.in (&study_gettextize): New.
13616 (&autoreconf): Handle newest gettextize.
13617 Rerun aclocal if needed.
13618 Suggested by Andreas Schwab.
13620 2002-03-13 Akim Demaille <akim@epita.fr>
13622 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13624 2002-03-13 Akim Demaille <akim@epita.fr>
13626 * doc/autoconf.texi (Header Portability): New.
13627 Add information about stdint.h and inttypes.h from Paul Eggert.
13629 2002-03-13 Akim Demaille <akim@epita.fr>
13631 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13632 -p'.
13633 From Bob Proulx.
13635 2002-03-12 Akim Demaille <akim@epita.fr>
13637 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13638 m4_require.
13640 2002-03-11 Andreas Schwab <schwab@suse.de>
13642 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13643 does not do it if --with-lispdir is given.
13645 2002-03-08 Akim Demaille <akim@epita.fr>
13647 Version 2.53.
13649 2002-03-08 Akim Demaille <akim@epita.fr>
13651 * doc/autoconf.texi (Subdirectories): Clarify that the
13652 subdirectory should exist.
13654 2002-03-08 Akim Demaille <akim@epita.fr>
13656 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13658 2002-03-08 Akim Demaille <akim@epita.fr>
13660 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13661 aliases the actual variables, and modifications of the former
13662 affect the latter.
13664 2002-03-08 Akim Demaille <akim@epita.fr>
13666 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13667 because of C-c: have m4 output in tmp files, then mv them.
13669 2002-03-08 Akim Demaille <akim@epita.fr>
13671 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13672 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13673 * bin/ifnames.in: Copyright update.

13677 * doc/autoconf.texi (Invoking autom4te): New.
13679 2002-03-05 Akim Demaille <akim@epita.fr>
13681 * doc/autoconf.texi (Specifying Names): Clarification suggested by
13682 Kevin Ryde.
13684 2002-03-05 Akim Demaille <akim@epita.fr>
13686 Version 2.52i.
13688 2002-03-04 Akim Demaille <akim@epita.fr>
13690 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13691 * lib/autoconf/general.m4 (AC_INIT): More informative error
13692 message for LIBOBJ.
13694 2002-03-04 Akim Demaille <akim@epita.fr>
13696 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13697 parallel builds.
13699 2002-03-04 Akim Demaille <akim@epita.fr>
13701 * doc/autoconf.texi (Transforming Names): Equality between target
13702 and host is irrelevant.
13703 (Specifying Names, Canonicalizing): Remove all references to the
13704 backward compatibility hooks. Rather, collect them all into...
13705 (Hosts and Cross-Compilation): this new section.
13706 * doc/install.texi (System Type): Ditto.
13707 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13708 that `--host' implies cross-compilation.
13710 2002-03-04 Akim Demaille <akim@epita.fr>
13712 * doc/autoconf.texi (Evaluation Macros): New.
13713 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13714 useless.
13715 (_m4_foreach): Define the variant with immediate evaluation so
13716 that it contains exactly the items, not an expression which
13717 evaluation is the current item.
13718 (m4_re_string, m4_re_word): Don't over quote them.
13720 2002-03-04 Akim Demaille <akim@epita.fr>
13722 Instead of having stacking `shift's evaluated at the end, let
13723 `foreach' loops immediately evaluate them.
13725 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13726 $*. This is the n-th time I change my mind, but hopefully this is
13727 the last...
13728 (m4_lquote): New.
13729 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13730 efficient.
13731 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13732 it was only a hack for m4_text_wrap.
13733 (m4_car2): Remove, replaced by...
13734 (m4_cdr): New.
13735 (_m4_foreach): Adjust.
13736 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13737 m4_bpatsubst for clarification.
13739 2002-03-04 Akim Demaille <akim@epita.fr>

13777 Version 2.52h.
13779 2002-02-07 Akim Demaille <akim@epita.fr>
13781 Fix Autoconf PR/209.
13782 Also reported by Frank Denis.
13784 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13786 2002-02-07 Akim Demaille <akim@epita.fr>
13788 Fix Autoconf PR/207:
13789 AC_PREFIX_PROGRAM fails with dashed program names
13791 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13792 variable when looking for the prefix program.
13793 Now it also works for shell variables.
13795 2002-02-07 Akim Demaille <akim@epita.fr>

13803 case/esac, some shells don't support it.
13804 Reported by Zack Weinberg.
13805 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
13807 2002-02-06 Akim Demaille <akim@epita.fr>

13816 is not available.

13821 Describe HP-UX cc bug workaround more accurately.
13822 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13823 not unsigned long.
13824 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13825 cross-compilers, too. This undoes some of the most recent change
13826 to this file.
13828 2002-02-05 Akim Demaille <akim@epita.fr>
13830 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13831 to make sure they are up to date when `check' is run.
13833 2002-02-05 Akim Demaille <akim@epita.fr>
13835 * doc/autoconf.texi (Making testsuite Scripts): Document
13836 package.m4.
13838 2002-02-05 Akim Demaille <akim@epita.fr>
13840 * lib/freeze.mk: New.
13842 2002-02-05 Akim Demaille <akim@epita.fr>
13844 Implement `autom4te --freeze'.
13846 * bin/autom4te.in (&freeze): New.
13847 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13848 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13850 2002-02-05 Akim Demaille <akim@epita.fr>
13852 * bin/autom4te.in (&parse_args): Implement `frozen files are
13853 optional are the sum of the previous files on the command line'.
13854 Also, pass `--reload-state=' on them, so...
13855 (handle_m4): don't.
13856 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13857 (M4sh): Rely on M4sugar.
13858 (Autotest, M4sh, M4sugar): Use frozen files.
13860 2002-01-31 Akim Demaille <akim@epita.fr>
13862 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13863 * doc/autoconf.texi (Initializing configure): Adjust.
13865 2002-01-30 Akim Demaille <akim@epita.fr>
13867 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13868 alphanumeric to `-' instead of `_'.
13870 2002-01-30 Akim Demaille <akim@epita.fr>
13872 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13873 for plain code, the other for cross-compilation code. The latter
13874 is now run with GCC only.
13875 * doc/autoconf.texi (Compilers and Preprocessors): New.
13877 2002-01-30 Akim Demaille <akim@epita.fr>
13879 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13880 values.
13881 * doc/autoconf.texi (Initializing configure): Explain how to
13882 change AC_INIT default values.
13884 2002-01-29 Akim Demaille <akim@epita.fr>
13886 * tests/torture.at (Configuring subdirectories): Use configure.in,
13887 so that aclocal 1.4 works.
13888 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13890 2002-01-28 Akim Demaille <akim@epita.fr>
13892 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13893 needs an argument.
13895 2002-01-28 Akim Demaille <akim@epita.fr>
13897 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13898 AUTOTEST_PATH *after* it was set.
13899 Don't put `.' in the PATH: the user should be precise and `./' if
13900 needed. In addition, given that the test suite does some `cd', if
13901 `.' is in the path, the `tested programs' sections will report
13902 programs found in the test suite's directory, while during the
13903 tests (performed in their own directory), these programs are no
13904 longer visible. In other words, the results is confusing and
13905 useless.
13906 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13908 2002-01-24 Akim Demaille <akim@epita.fr>
13910 Version 2.52g.
13912 2002-01-24 Akim Demaille <akim@epita.fr>
13914 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
13915 * doc/autoconf.texi: Finally add Akim as an author.
13917 2002-01-24 Akim Demaille <akim@epita.fr>
13919 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13920 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13921 Bourne. Use /bin/sh.
13922 From Andreas Buening.
13924 2002-01-24 Akim Demaille <akim@epita.fr>
13926 * config/config.guess, config/config.sub, config/texinfo.tex:
13927 Update from masters.
13929 2002-01-24 Akim Demaille <akim@epita.fr>

13932 * config/auxdir.m4, config/cond.m4, config/depend.m4,
13933 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
13934 * config/missing.m4, config/sanity.m4, config/select.m4,
13935 * config/strip.m4: Remove, to ease sync'ing with any version of
13936 Automake.
13938 2002-01-24 Akim Demaille <akim@epita.fr>
13940 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13941 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13942 Reported by Geir Ove Myhr.
13944 2002-01-21 Akim Demaille <akim@epita.fr>
13946 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13948 2002-01-21 Akim Demaille <akim@epita.fr>
13950 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13951 message on invalid options.
13952 * bin/autom4te.in (parse_args): Don't use
13953 Autoconf::General::getopt with non valid options.
13955 2002-01-17 Jim Meyering <meyering@lucent.com>
13957 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13958 $ac_cv_exeext so we don't use an old, invalid, cached value.
13960 2002-01-11 Akim Demaille <akim@epita.fr>
13962 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13963 Meyering.

13965 limitation.

13969 2002-01-06 Akim Demaille <akim@epita.fr>
13971 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13972 package.m4, since is really depends upon configure.ac, not
13973 configure.
13974 * doc/autoconf.texi (testsuite Scripts): Adjust.
13975 * tests/Makefile.am (package.m4): New.
13976 EXTRA_DIST it since its a source.
13978 2002-01-06 Akim Demaille <akim@epita.fr>
13980 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13981 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13982 and PACKAGE_BUGREPORT from here...
13983 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13984 arguments.
13985 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13986 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13987 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13988 * tests/tools.at (autoheader): Adjust.
13989 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
13991 2002-01-06 Akim Demaille <akim@epita.fr>

13995 2002-01-03 Akim Demaille <akim@epita.fr>
13997 * doc/autoconf.texi (Output): Improved wording regarding use of
13998 AC_OUTPUT.
13999 From Olly Betts.
14001 2001-12-18 Kevin Ryde <user42@zip.com.au>
14003 * doc/autoconf.texi (Function Portability): Add notes on sscanf
14004 sometimes needing writable input.
14006 2001-12-17 Jim Meyering <meyering@lucent.com>
14008 * doc/autoconf.texi (New Macros): Tweak wording.
14010 2001-12-14 Akim Demaille <akim@epita.fr>
14012 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
14013 trailing files, don't apply `-rf' to files which might not be
14014 created by configure (core, core.*, and *.core), but just `rm -f'.
14015 Suggested by Jonathan Kamens.
14017 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
14019 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
14021 2001-12-14 Akim Demaille <akim@epita.fr>
14023 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
14025 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
14027 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
14028 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
14029 abs_srcdir, top_srcpath to abs_top_srcdir.
14030 (_AC_OUTPUT_FILES): Adjust.
14031 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
14032 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
14033 * tests/wrappl.in, tests/wrapsh.in: Adjust.
14035 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
14037 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
14038 C/Fortran linking on HP/UX, by extracting the Fortran library
14039 search path from the LPATH line in the $F77 -v output.
14041 2001-12-12 Kevin Ryde <user42@zip.com.au>
14043 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
14044 forbidden file descriptors table.
14046 2001-11-26 Akim Demaille <akim@epita.fr>
14048 * bin/autoscan.in (%c_keywords): Build it at top level.
14049 Map to 1 in order to simplify its uses.
14051 2001-11-26 Akim Demaille <akim@epita.fr>
14053 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
14054 Remove $filepath, useless.
14055 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
14056 variables, they are really part of the tokens.
14057 Split the input line on spaces and then look for tokens.
14058 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
14059 because of `lex$U.$(OBJEXT)'.
14060 (&scan_files): Use "@list" instead of join.
14061 * doc/Makefile.am (CLEANFILES): Add *.fns.
14063 2001-11-26 Akim Demaille <akim@epita.fr>
14065 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
14066 Remove, replaced by...
14067 * tests/wrappl.in: Be common for all the Perl executables.
14068 In particular autoscan and autoheader want -I.
14069 * configure.ac: Adjust.
14070 * lib/autoscan/headers: errno.h is portable.
14072 2001-11-26 Akim Demaille <akim@epita.fr>
14074 * bin/autoscan.in (used): New.
14075 Use it.
14077 2001-11-26 Akim Demaille <akim@epita.fr>
14079 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
14080 directives.
14081 (&scan_sh_file): Remove a duplicate pattern.
14082 (&check_configure_ac): Use long options.
14083 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
14085 2001-11-26 Akim Demaille <akim@epita.fr>
14087 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
14088 Before, having a line containing the opening of a multi line
14089 comment made the whole line be ignored.
14091 2001-11-26 Akim Demaille <akim@epita.fr>
14093 * doc/autoconf.texi (Using an Autotest Test Suite): New.
14094 (testsuite Scripts): Be one of its subsection.
14095 (Autotest Logs): New.
14097 2001-11-26 Akim Demaille <akim@epita.fr>
14099 Test groups are now run two directories deeper.
14101 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
14102 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
14103 at_top_builddir.
14104 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
14105 top_srcdir, builddir and top_builddir.
14106 Use `at_*dir' relatively to the directory containing the
14107 suite, use `*dir' when relatively to the current group dir.
14109 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14111 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14112 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14113 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14114 spelling errors.
14116 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14118 * doc/autoconf.texi (Using System Type): Add an example of `case
14119 $host' usage so people quit using `case $target' everywhere.
14121 2001-11-22 Akim Demaille <akim@epita.fr>
14123 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14124 spotted by Jim Meyering.
14126 2001-11-16 Paul Eggert <eggert@twinsun.com>
14128 This patch implements a `long double' suggestion by Oliver Kiddle.
14130 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14131 static, to catch errors if the value isn't known at compile-time
14132 and the compiler supports dynamic arrays. Change its name from
14133 `_array_' to `test_array' to avoid potential name clashes.
14134 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14135 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14136 better than double. Catch a bug in GCC 2.95.2 x86.
14137 * doc/autoconf.texi (C Compiler): Document the above.
14138 * NEWS: Likewise.
14140 2001-11-13 Akim Demaille <akim@epita.fr>
14142 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14143 hand.
14144 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14146 2001-11-13 Akim Demaille <akim@epita.fr>
14148 * lib/autotest/general.m4 (AT_INIT): After having run the test
14149 group, go back to the initial directory, not to at_suite_dir.
14151 2001-11-13 Akim Demaille <akim@epita.fr>
14153 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14154 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14155 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14156 option.
14157 (AT_CHECK_CONFIGURE): Use absolute paths.
14158 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14159 The problem is still the old one: there is no means in M4 (that I
14160 know about) to create a defining macro, because there is no means
14161 to create `$1' etc., therefore, the defining macro ``swallows''
14162 all the arguments meant to the defined macro.
14164 2001-11-13 Akim Demaille <akim@epita.fr>
14166 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14167 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14168 configure.ac.
14169 * tests/aclocal.m4: Remove, as it is no longer used.
14171 2001-11-13 Akim Demaille <akim@epita.fr>
14173 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14174 variable names when referring to a single test group, or to
14175 `suite' when referring to the whole test suite.
14176 `at_last_test' is removed: m4 compute at_format itself.
14177 (at_stdout, at_stder1, at_stderr): New variables.
14178 (AT_CHECK): Use them.
14180 2001-11-13 Akim Demaille <akim@epita.fr>
14182 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14183 in PATH.
14184 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14185 Do it as soon as a test fails, don't wait till the end of the test
14186 suite.
14187 Don't remove $as_me.[0-9]*, since these files no longer exist.
14189 2001-11-13 Akim Demaille <akim@epita.fr>
14191 * tests/tools.at: Use absolute paths, since we are no longer run
14192 in place.
14194 2001-11-13 Akim Demaille <akim@epita.fr>
14196 Now that tests are running in their own private dir, there is no
14197 need to list the files to remove at the end of tests groups.
14199 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14200 (AT_data_files, at_data_files): Remove.
14201 (AT_CLEANUP, AT_DATA): Simplify.
14202 (AT_INIT): Adjust.
14203 Remove the group dir if !debug && !failed.
14204 * tests/atspecific.m4: Adjust.
14206 2001-11-13 Akim Demaille <akim@epita.fr>
14208 Start a new layout for Autotest: `testsuite' creates
14209 `testsuite.dir' in which the at-check-line etc. files are to be
14210 found, and `testsuite.dir/003' where the test group 3 is run.
14212 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14213 at_check_line_file, at_format, at_test_normalized, at_group_dir
14214 are new variables.
14215 Create the directories.
14216 Use absolute paths for at- files.
14217 (AT_CHECK): Adjust.
14219 2001-11-11 Michael Matz <matz@kde.org>
14221 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14222 (m4_car2): New.
14223 (m4_car): Properly quote arguments.
14225 2001-11-13 Akim Demaille <akim@epita.fr>
14227 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14228 with stricter rules on LIBOBJS.
14230 2001-11-12 Paul Eggert <eggert@twinsun.com>
14232 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14233 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14234 __PROTOTYPES too.
14236 2001-11-12 Akim Demaille <akim@epita.fr>
14238 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14240 2001-11-12 Akim Demaille <akim@epita.fr>
14242 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14243 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14244 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14245 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14246 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14247 specify to what the macro should be defined (typically to 1).
14249 2001-11-12 Akim Demaille <akim@epita.fr>
14251 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14252 From Jim Meyering.
14254 2001-11-12 Akim Demaille <akim@epita.fr>
14256 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14257 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14258 definition used by Automake where LEX is +/- "${missing} lex" and
14259 `missing' itself contains variables.
14261 2001-11-12 Akim Demaille <akim@epita.fr>
14263 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14264 Now that M4sh pushes BODY, the comments were output at the end of
14265 the test suites.
14267 2001-11-08 Akim Demaille <akim@epita.fr>
14269 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14270 that we can trace macros from aclocal.m4.
14271 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14272 obsoleted, and redirect to the former anyway.
14273 Reported by Ralf Corsepius.
14275 2001-11-08 Akim Demaille <akim@epita.fr>
14277 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14278 processed only if present.
14279 * tests/torture.at (Configuring subdirectories): Use autoreconf
14280 instead of successive calls to autoconf.
14281 Add a nonexistent subdirectory to exercise the patch above.
14282 Reported by Ralf Corsepius.
14284 2001-11-08 Kevin Ryde <user42@zip.com.au>
14286 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14287 doesn't accept .S files.
14289 2001-11-07 Akim Demaille <akim@epita.fr>
14291 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
14292 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
14293 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14294 * bin/autom4te.in (warn_forbidden): New.
14295 (handle_output): Use it.

14307 From Nicolas Joly.
14309 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14311 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

14328 Use and export them.
14329 (&find_configure_ac): Optionally take a directory where to look at.
14330 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of

14341 Add basename, dirname, and fileparse.
14342 (@EXPORT): Adjust.
14343 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14344 Don't look for aclocal flags if we already know aclocal is not
14345 used.
14346 Move aclocal.m4t only if it exists.
14347 Reported by Ezra Peisach.
14349 2001-11-03 Akim Demaille <akim@epita.fr>
14351 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14352 passed on command line, defaulting to ./configure.ac if present.
14353 (&maybe_autoreconf, File::Find): Remove, unused.
14354 (&autoreconf): If autoconf is not used, don't try to trace.
14356 2001-11-02 Akim Demaille <akim@epita.fr>
14358 * configure.ac: Bump to 2.52g.
14360 2001-11-02 Akim Demaille <akim@epita.fr>
14362 Version 2.52f.
14364 2001-11-02 Akim Demaille <akim@epita.fr>
14366 * config/config.guess, config/config.sub, doc/standards.texi:
14367 * config/lispdir.m4: Update from masters.
14368 * configure.ac: Bump to 2.52f.
14370 2001-11-02 Akim Demaille <akim@epita.fr>
14372 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14373 Don't run aclocal when aclocal.m4 is not from aclocal.
14374 From Ezra Peisach.
14375 Don't run libtoolize and gettextize if --install is not given.
14377 2001-11-01 Paul Eggert <eggert@twinsun.com>
14379 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14380 be invoked before _AS_LINENO_PREPARE.
14381 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14382 than character ranges.
14384 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14385 invoking AS_BASENAME. Set the locale variables to 'C' if
14386 possible, as POSIX requires this to get the traditional
14387 behavior.
14388 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14390 2001-10-31 Paul Eggert <eggert@twinsun.com>
14392 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14393 with {}, as that triggers a bug in Bash 2.05.
14395 (_AS_LINENO_PREPARE): Use Sed rather than
14396 Awk. Fix the sed prepass to work even if there are multiple
14397 instances of $LINENO on the same line. Do not substitute for
14398 other variables like $LINENOT. Do not check file dates; such a
14399 check is unreliable on sufficiently fast machines, and removing
14400 the check makes the code simpler and more reliable. Check for
14401 output and chmod failures.
14403 * doc/autoconf.texi (Special Shell Variables): Document
14404 the above.
14406 2001-10-31 Akim Demaille <akim@epita.fr>
14408 * tests/Makefile.am (atconfig): Remove this target, Automake
14409 handles it now.
14411 2001-10-31 Akim Demaille <akim@epita.fr>
14413 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14414 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14415 provided, while it is optional.
14416 * configure.ac: Adjust.
14418 2001-10-26 Paul Eggert <eggert@twinsun.com>
14420 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14421 lib/Autom4te/Struct.pm:
14422 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14423 with 5.005_02.
14425 * doc/autoconf.texi (Special Shell Variables): Document some
14426 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14428 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14429 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14430 eval $LINENO is not portable in practice.
14432 2001-10-24 Akim Demaille <akim@epita.fr>
14434 * lib/Autom4te/General.pm (backname): New.
14436 2001-10-24 Akim Demaille <akim@epita.fr>
14438 * m4/: Remove, merged into...
14439 * config/: here.
14441 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14443 * doc/autoconf.texi (Shellology): Mention the problems with bash
14444 2.05's use of ANSI quoting in its `set' builtin.
14446 2001-10-22 Paul Eggert <eggert@twinsun.com>
14448 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14449 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14450 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14451 POSIX decided to standardize on the int flavor of strerror_r.
14452 Always do char* test, as there's no reason not to.
14453 Assign to a char* var, to catch strerror_r that returns int*.
14455 * doc/autoconf.texi (Particular Functions):
14456 Document the above changes. Also, document the fact that
14457 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14459 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14461 2001-10-20 Akim Demaille <akim@epita.fr>
14463 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14464 the executable was missing from the log.

14468 * lib/Autom4te/General.pm (&update_file): If destination is
14469 unchanged, remove the source.
14470 (&up_to_date_p): Don't be verbose, be debug.
14471 * bin/autoreconf.in: No longer support --m4dir.
14472 (&autoreconf): Display the full path of the configure.ac we are
14473 studying.
14474 Trace it only once.
14475 Be sure to honor --force with gettextize.
14476 Always run aclocal.
14477 * doc/autoconf.texi: Adjust.
14479 2001-10-20 Akim Demaille <akim@epita.fr>
14481 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14482 Remove, dead.
14483 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14484 `intl' is already present, as it refuses unless --force.
14485 (&parse_args): Use -I, --include instead of the old Autoconf
14486 options.
14487 ($localdir, $autoconf_dir): Remove.
14488 (@include): New.
14489 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14491 2001-10-19 Jens Petersen <petersen@redhat.com>

14499 file in @configure_input@.
14500 Don't mention `automatically' in addition to `generated'.
14501 * tests/torture.at (#define header templates): Adjust.
14503 2001-10-19 Akim Demaille <akim@epita.fr>
14505 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
14506 comment, explain how to install automatic mode selection.
14507 From Russ Allbery.
14509 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14511 * bin/autoreconf.in (autoreconf): Display the path to the
14512 configure.ac being studied.
14514 2001-10-18 Paul Eggert <eggert@twinsun.com>
14516 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14517 long, to work around a bug in the HP C compiler version HP92453-01
14518 B.11.11.23709.GP.
14520 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14521 (AS_BASENAME_EXPR): New macro.
14522 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14523 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14524 and fall back on 'sed' only if the other two fail. This makes
14525 AS_BASENAME act more like AS_DIRNAME.
14526 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14527 contains white space.
14528 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14529 Use AS_DIRNAME, since I think it's now DOS-friendly.
14530 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14531 Allow "dirname //FOO" to return either / or //, as POSIX allows
14532 either behavior.
14534 2001-10-10 Akim Demaille <akim@epita.fr>
14536 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

14538 From Eric Sharkey.

14542 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14543 m4_define, since...

14582 bother with $force since...
14583 * lib/Autom4te/General.pm: does.
14585 2001-10-08 Akim Demaille <akim@epita.fr>
14587 * bin/autoreconf.in: Rewrite in Perl.

14661 * tests/tools.at (AT_DATA_FORBIDDEN): New.

14674 ourselves with CONFIG_SHELL.
14676 2001-10-05 Paul Eggert <eggert@twinsun.com>
14678 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

14682 2001-10-05 Akim Demaille <akim@epita.fr>
14684 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

14749 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
14750 Don't use nested parenthesization. This patch was originally
14751 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
14752 but somehow it didn't get incorporated then.
14753 * doc/autoconf.texi (Limitations of Usual Tools):
14754 Clarify remark about sed and nested parenthesization.

14757 Report an error if the size cannot be determined even though
14758 the type exists.
14759 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14760 Check for `expr' arithmetic overflow, and for compilation failure,
14761 and invoke a new argument $4 if either is discovered.
14762 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14763 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
14765 2001-09-28 Akim Demaille <akim@epita.fr>

14779 2001-09-27 Akim Demaille <akim@epita.fr>
14781 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
14782 generates too many bug reports.
14784 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
14785 status when executing the ACTION-IF-FALSE.
14786 * tests/base.at (AC_TRY_*): Rename as...

14804 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
14805 Raja R Harinath:
14806 Be sure to detect when $LINENO always returns the same value.
14807 Look for the original script, basename($0) is certainly not
14808 enough.
14809 Pass the CLI arguments to `$as_me.lineno'.

14830 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
14831 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
14832 builddir, buildpath, top_builddir, and top_buildpath.
14833 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
14834 the current directory.

14847 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
14848 Remove.

14859 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14860 (Programming in M4sh): this.

14904 * tests/Makefile.am (package.m4): Remove.
14906 2001-09-22 Akim Demaille <akim@epita.fr>
14908 Rely on `$LINENO' when possible instead of `__oline__'.
14910 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14911 `$LINENO' support replacement when not supported.
14912 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14913 them explicitly to be sure they are not output before this section
14914 (via m4_require). Cosmetic only.

14916 * lib/autoconf/programs.m4: Replace all the occurrences of

14920 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
14922 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14923 character (u: -> ue) in a code comment.
14924 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14925 it works.
14927 2001-09-21 Akim Demaille <akim@epita.fr>
14929 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14930 Suggested by Jim Meyering.
14932 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14934 * lib/autoconf/programs.m4: Use extensions listed in
14935 $ac_executable_extensions when looking for programs.
14937 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14939 * lib/autoconf/general.m4: Fix a small Englisho.

14947 PATH_SEPARATOR.
14948 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

14951 * lib/autotest/general.m4: Replace occurrences of ':' in
14952 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14954 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14956 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14957 arguments. Fixed a typo.
14959 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14961 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14962 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14964 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14966 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14967 * bin/autoupdate.in: Ditto.
14968 * bin/autoheader.in: Reworded a few comments.
14969 * bin/autoconf.in: Reworded help text for a few options.

14973 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14975 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14976 already have $file). Set output files to binary mode (helps avoid
14977 CR issues on DOSish systems).
14979 2001-09-19 Akim Demaille <akim@epita.fr>
14981 * lib/autotest/general.m4: Englishoes.
14982 From Tim Van Holder and Alexey Mahotkin.
14984 2001-09-18 Paul Eggert <eggert@twinsun.com>
14986 * doc/autoconf.texi (Common Shell Constructs): New node,
14987 documenting AS_DIRNAME.
14988 (Limitations of Usual Tools): Refer to it when discussing dirname.
14989 Also, update discussion of POSIX standard to reflect latest draft.
14991 * lib/autoconf/c.m4:
14992 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14994 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14995 Do not pass a first argument with leading '-'
14996 to expr, by parenthesizing initial integers that might be negative.
14998 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14999 now merely checks whether it is an error to pass an argument
15000 to getpgrp.
15002 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
15003 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
15004 whether it is a (compile-time) error to pass an argument to
15005 getpgrp. This simpler test supports the revised documentation,
15006 and is all that AC_FUNC_GETPGRP's users really need.
15008 2001-09-18 Akim Demaille <akim@epita.fr>
15010 * doc/autoconf.texi (Limitations of Make) <$<>: New.
15012 2001-09-18 Akim Demaille <akim@epita.fr>

15020 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
15021 correctly.
15022 Add test for AS_BASENAME.
15023 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
15024 added test. It now correctly handles /1/2/3/, returning '3' not ''.
15025 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
15026 * tests/base.at: Fixed the expected responses. The old ones were
15027 one line out...
15028 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
15029 the documentation claims it should (and how it behaved in 2.13).
15031 2001-09-18 Akim Demaille <akim@epita.fr>
15033 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
15034 the AC_CONFIG_COMMANDS invocation.
15035 This also solves the name clash problems.
15036 Don't set the package's ID.
15037 * lib/m4sugar/Makefile.am (version.m4): Revamp.
15038 No longer to be shipped.
15039 (version.in): Remove.
15040 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
15041 * lib/autoconf/status.m4: Adjust.
15042 Use `m4_PACKAGE_STRING'.
15043 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
15044 the only optional argument is the name of the test suite.
15045 Expect `package.m4' to define the package signature.
15046 * lib/autom4te.in (Autotest): Add `package.m4?'.
15047 * tests/Makefile.am (package.m4): New.
15048 * tests/suite.at: ifnames is a victim.
15050 2001-09-18 Akim Demaille <akim@epita.fr>
15052 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
15053 AC_LIBSOURCE, AC_CONFIG_FILES.
15054 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
15055 program version string doesn't match the package's.
15056 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
15057 after `(cached)'.

15061 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15062 Allow expression to return any value that can fit into unsigned long
15063 (not int, as before). Check for output errors.
15065 2001-09-17 Bruno Haible <haible@ilog.fr>
15067 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15068 Always include <stdio.h> and <stdlib.h>. Evaluate
15069 the expression in an extra function before these includes. Call
15070 fprintf "%d" only after ensuring the argument is of type 'int'.
15071 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
15073 2001-09-17 Paul Eggert <eggert@twinsun.com>
15075 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
15076 or CFLAGS=-O5. In that case, the linker has a relaxed view of
15077 fatal errors, and AC_CHECK_LIB causes it to include libraries even
15078 when they don't exist.
15080 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
15081 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
15082 need it.
15084 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
15085 version with the version used by fileutils 4.1, except use
15086 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
15087 we don't need it.
15089 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
15091 2001-09-13 Akim Demaille <akim@epita.fr>
15093 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
15094 _first_.
15095 Reported by Gerrit P. Haase.
15097 2001-09-13 Akim Demaille <akim@epita.fr>
15099 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

15112 (m4_re_escape): New.
15113 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
15114 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
15115 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
15116 Likewise.
15117 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
15118 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
15119 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
15120 AT_tests_all for consistency.
15121 Set at_victims.
15122 (AT_VICTIMS): Similar to AT_KEYWORDS.
15123 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
15125 2001-09-13 Akim Demaille <akim@epita.fr>
15127 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
15129 2001-09-13 Akim Demaille <akim@epita.fr>
15131 * lib/autotest/general.m4 (AT_INIT): Create and remove
15132 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15133 test suites can cohabit.
15135 2001-09-13 Akim Demaille <akim@epita.fr>
15137 * tests/mktests.sh: Don't output banners for empty test files.
15139 2001-09-13 Akim Demaille <akim@epita.fr>
15141 Test suites can be run independently of configure.
15143 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
15144 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

15156 (Syntax of the shell scripts): Don't check ifnames.
15157 (AT_CHECK_PERL_SYNTAX): New.

15178 (_AT_CLEANUP_FILE_IF): Simplify the regexp.
15179 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
15180 No longer fill the HELP diversion.
15181 (AT_CLEANUP): Use them.
15182 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
15183 (m4_list_append): Remove.
15185 Spread a few keywords in the Autoconf test suite.
15187 2001-09-10 Akim Demaille <akim@epita.fr>
15189 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

15202 * tests/semantics.at (AC_PATH_PROG & AC_PATH_PROGS)
15203 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
15205 2001-09-07 Akim Demaille <akim@epita.fr>
15207 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
15208 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
15209 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
15210 related variables into `at_package_*'.
15211 * lib/autotest/general.m4 (AT_VICTIMS): New.
15212 (AT_INIT): Adjust for stand-alone/embedded test suites.
15213 (AS_MESSAGE_LOG_FD): Define and use it.
15214 * tests/suite.at (AT_VICTIMS): Use it.
15215 * tests/tools.at (autoupdating AC_PREREQ): Don't depend upon
15216 at_version.
15218 2001-09-07 Akim Demaille <akim@epita.fr>
15220 Move toward possibly stand-alone test suites.
15222 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
15223 in addition, it introduces useless differences in logs.
15224 (AT_INIT): Let atconfig and atlocal be both optional.
15225 Adjust PATH computation.
15226 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
15228 2001-09-07 Akim Demaille <akim@epita.fr>
15230 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon
15231 m4sugar/version.m4.
15233 2001-09-05 Akim Demaille <akim@epita.fr>
15235 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

15237 From Uwe Seimet.
15239 2001-09-05 Akim Demaille <akim@epita.fr>
15241 * bin/autom4te.in: --language is -l, not -s.
15243 2001-09-05 Akim Demaille <akim@epita.fr>
15245 Be ready to handle filenames as stupid as `dnl.at', for if even
15246 the maintainer is dumb enough to do that...
15248 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15249 excellence in M4 quotation: consider `__file__' is active.
15251 And BTW, when invoking m4, pass the --include in the right order:
15252 the wrong one.
15254 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
15255 4m.
15257 2001-09-05 Akim Demaille <akim@epita.fr>
15259 * lib/Autom4te/XFile.pm: New lib file.
15260 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
15261 * bin/autoheader.in: Use it.
15263 2001-09-05 Akim Demaille <akim@epita.fr>
15265 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
15266 defined.
15268 2001-09-05 Akim Demaille <akim@epita.fr>
15270 * lib/Autom4te/General.pm (&getopt): Work around the `-' Getopt bug.
15271 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust.
15273 * bin/autoscan.in: Use `getopt' and `find_files' etc.
15274 Add -I, --include support.
15275 * doc/autoconf.texi (autoscan Invocation): Adjust.
15277 2001-09-05 Akim Demaille <akim@epita.fr>
15279 CVS GNU M4 doesn't like `undefine(undefined)'.
15281 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
15282 New, extracted from main.
15283 Use IO::File wherever possible.
15284 (input.m4): Be constant, use -I instead of hard coding $tmp.
15285 Therefore be a quoted heredoc.
15286 Don't invoke `_au_disable', since ac was not loaded, but just
15287 `unm4.m4'.
15289 2001-08-31 Akim Demaille <akim@epita.fr>
15291 Version 2.52d.
15293 2001-08-31 Akim Demaille <akim@epita.fr>
15295 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
15296 previous patch.
15297 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
15299 2001-08-31 Akim Demaille <akim@epita.fr>
15301 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
15302 serious problems handling heredocs in heredocs.
15303 Reported by Nicolas Joly.
15305 2001-08-31 Akim Demaille <akim@epita.fr>
15307 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
15308 (Making testsuite Scripts): Update.
15310 2001-08-31 Akim Demaille <akim@epita.fr>
15312 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
15314 2001-08-31 Akim Demaille <akim@epita.fr>
15316 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
15317 (testsuite Scripts): There is no such thing as `atconfig.in'.
15318 And actually one diagram is missing: test suite runtime.
15320 2001-08-31 Akim Demaille <akim@epita.fr>
15322 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
15323 inverse order.
15325 2001-08-31 Akim Demaille <akim@epita.fr>
15327 * bin/autoupdate.in (@include): `installcheck' revealed the path
15328 to m4sugar was lacking!
15330 2001-08-31 Akim Demaille <akim@epita.fr>
15332 * man/Makefile.am (.x.1): We really have to pass
15333 autom4te_perllibdir.
15335 2001-08-31 Akim Demaille <akim@epita.fr>
15337 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
15338 debug scripts, in particular passing explicitly listed tests to
15339 run is stupid.
15341 2001-08-31 Akim Demaille <akim@epita.fr>
15343 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
15344 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
15345 Use directly autom4te, not autoconf.
15346 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
15348 2001-08-31 Akim Demaille <akim@epita.fr>
15350 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
15351 * bin/autoheader.in (%symbol): Strip arguments of macros.

15357 2001-08-31 Akim Demaille <akim@epita.fr>
15359 * bin/autom4te.in (&parse_args): Die on unknown languages.
15360 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
15361 need for autoconf.
15362 Promote --include over --macrodir and other obsolete options.
15364 2001-08-31 Akim Demaille <akim@epita.fr>
15366 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
15367 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
15368 * bin/autom4te.in ($autoconf): Pass --force.
15369 `print $out' doesn't print `$_' but `$out'.
15370 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
15371 (autoheader): Pass --force since the test suite goes too fast for
15372 the time stamps.
15373 Adjust to the new autoheader messages.
15375 2001-08-31 Akim Demaille <akim@epita.fr>
15377 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
15378 Check the completeness of the #template.
15379 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
15380 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
15381 invocation.
15383 2001-08-31 Akim Demaille <akim@epita.fr>
15385 * lib/Autom4te/General.pm (&find_file, &update_file): New.
15386 * bin/autoupdate.in, bin/autoheader.in: Adjust.
15387 Drop AC_MACRODIR dead for real.
15388 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15389 `autoheader: `config.hin' is created'.
15390 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15392 2001-08-31 Akim Demaille <akim@epita.fr>
15394 * bin/autoheader.in: Rewrite in Perl.
15395 * tests/autoheader: Adjust.
15397 2001-08-31 Akim Demaille <akim@epita.fr>
15399 * bin/autoconf.in (--include, -I): New option.
15400 Map --localdir, --autoconf-dir onto it.
15401 Forward autom4te's options instead of interpreting them.
15402 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15403 There is no such envvar since the inception of autom4te.cfg.
15404 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15405 * bin/autoupdate.in: Adjust, and perform more control.
15406 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15407 * tests/autoconf: Dittowise.
15409 2001-08-31 Akim Demaille <akim@epita.fr>
15411 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15412 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15413 optionally `FILE'.
15414 Use -e, not -f, since /dev/null for instance is OK.
15415 (&parse_args): Adjust.
15416 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15418 2001-08-31 Akim Demaille <akim@epita.fr>
15420 * configure.ac: Also find tested executables in bin.
15421 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
15422 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
15423 installed peer executables, only PATH is allowed to resolve it.
15424 Pass `autoconf_dir' via options, not via invisible envvars.
15425 * lib/Autom4te/General.pm (&find_peer): Remove.
15426 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15427 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15428 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15429 find the executables for it.
15430 * tests/Makefile.am: Major cleanup. Too lazy to document...
15431 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15432 We only need PERL.
15433 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15434 indeed related to running the test suite, while passing
15435 --autoconf-dir and others is related to running non installed
15436 Autoconf executables. So don't do that, leave it to...
15437 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15438 * tests/autoscan: New.
15439 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15440 refer to library files: rely on --language.
15442 2001-08-29 Akim Demaille <akim@epita.fr>
15444 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
15445 s/--set/--language/.
15447 2001-08-29 Akim Demaille <akim@epita.fr>
15449 * doc/autoconf.texi: Strip the @nodes.
15450 Suggested by Paul Eggert.
15451 (Initializing configure): Typo.
15453 2001-08-29 Akim Demaille <akim@epita.fr>
15455 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15456 Suggested by Paul Eggert.
15458 2001-08-29 Akim Demaille <akim@epita.fr>
15460 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15461 download in a tmp dir.
15463 2001-08-29 Akim Demaille <akim@epita.fr>
15465 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
15466 case insensitive OSes out there :(
15467 From Tim Van Holder.
15469 2001-08-29 Akim Demaille <akim@epita.fr>
15471 * lib/autom4te.in: New.
15472 * lib/Makefile.am (edit, autom4te.cfg): New.
15473 * bin/autom4te.in (BEGIN): Simplify.
15474 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
15475 (&load_configuration): New. Use it.
15476 (&parse_args): Support --mode, --set, and --melt.
15477 * bin/autoconf.in: Simplify and adjust.
15478 * tests/Makefile.am (AUTOMAKE): Use --set.
15479 * tests/atlocal.in: Adjust.
15480 * BUGS: distcheck and check are weak.
15482 2001-08-29 Akim Demaille <akim@epita.fr>
15484 * lib/autotest/general.m4: Use
15485 foo=`(command) 2>/dev/null`
15486 not
15487 foo=`command` 2>/dev/null
15488 (at-devnull): Rename as...
15489 (AT-devnull): this.
15490 (--clean): Remove AT-* files too.
15491 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
15492 Reported by Nicolas Joly.
15494 2001-08-28 Akim Demaille <akim@epita.fr>
15496 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
15497 quotes inside single quotes.
15498 Reported by Nicolas Joly.
15500 2001-08-28 Kevin Ryde <user42@zip.com.au>
15502 * doc/autoconf.texi (Function Portability): Mention C right shifts.
15504 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
15506 * lib/autotest/general.m4: Reword some messages.
15507 (AT_INIT): Check for the `times' builtin before using it.
15508 Support test ranges as arguments to the testsuite.
15509 Have -e imply -d as the help text suggested.
15511 2001-08-27 Akim Demaille <akim@epita.fr>
15513 * Makefile.maint: Formatting changes.
15514 (do-po-update, po-update, cvs-update, update): New targets.
15515 (AMTAR): Remove.
15517 2001-08-27 Akim Demaille <akim@epita.fr>
15519 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

15524 2001-08-27 Akim Demaille <akim@epita.fr>
15526 * lib/autotest/general.m4 (AT_INIT): Log the command line.
15527 Support `VAR=VAL' as arguments.
15528 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
15529 may be set via the command line.
15531 2001-08-27 Akim Demaille <akim@epita.fr>
15533 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
15534 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
15535 first the build dirs, then the src dirs.
15536 * configure.ac (AC_CONFIG_TESTDIR): Adjust.
15538 2001-08-27 Akim Demaille <akim@epita.fr>
15540 * lib/autotest/general.m4 (AT_INIT): Output the definition of
15541 at_data_files earlier.

15545 2001-08-27 Akim Demaille <akim@epita.fr>
15547 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
15548 `ac_top_builddir' to mimic Automake's vocabulary, which much more
15549 readable.
15550 Adjust callers.
15551 * doc/autoconf.texi (Configuration Actions): Document the vars
15552 available in commands.
15553 Emphasize the risks of collisions in init-cmds.
15555 2001-08-27 Akim Demaille <akim@epita.fr>
15557 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
15558 (Initializing configure): this new node.
15560 2001-08-27 Akim Demaille <akim@epita.fr>
15562 * Makefile.am (EXTRA_DIST): INSTALL.txt is a dead hack.

15573 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move
15574 to...
15575 * lib/autoconf/autoheader.m4: this new file.
15576 * lib/autoconf/general.m4 (AH_OUTPUT, AH_VERBATIM)

15581 2001-08-27 Akim Demaille <akim@epita.fr>
15583 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
15584 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
15585 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
15586 -> ac_dir).
15587 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
15588 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
15590 2001-08-27 Akim Demaille <akim@epita.fr>
15592 * lib/autoconf/autoconf.m4 (AC_CONFIG_COMMANDS)

15615 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
15616 (AMTAR): Help automake define it.
15617 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
15618 needed, 1.5 can have a macro and a target with the same name.
15619 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
15620 * m4/strip.m4: New.

15633 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
15634 Adjust callers.
15635 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15636 the name of the directory they're in, instead of the filename,
15637 since version.m4 is now in m4sugar, but m4_acversion must not be
15638 classified as an Autoconf macro.
15639 ($input_m4): Don't qualify the path to m4sugar.
15640 Rather, pass autoconf_dir to m4.
15641 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
15642 * tests/suite.at: Require 2.52c.
15644 2001-08-27 Akim Demaille <akim@epita.fr>

15726 * NEWS, README, README-alpha, TODO, tests/README: This package is

15729 2001-08-20 Akim Demaille <akim@epita.fr>
15731 Info readers seem to need `Index' in the index node title :(
15733 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15734 simplified index node names.

15778 2001-08-20 Akim Demaille <akim@epita.fr>
15780 Huh!?!?! There are still some user EOF tags used, which prevents
15781 their use in AC_CONFIG_COMMANDS for instance...
15783 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15784 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

15847 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

15863 2001-08-17 Akim Demaille <akim@epita.fr>
15865 * doc/autoconf.texi: Work around Texinfo buglets.
15866 (Transformation Rules): One example is enough, users are expected
15867 to have their brains on. And BTW, use DESTDIR.
15868 (dvar): New macro. Use it.
15870 2001-08-17 Akim Demaille <akim@epita.fr>
15872 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15917 * Makefile.maint (CVS): New.
15918 (local-check): Run changelog-check. last.
15919 (alpha): Don't depend upon local-check, since...
15920 (cvs-dist): depends upon it.
15922 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15924 * tests/Makefile.am: Use a clean-local rule to remove
15925 autom4te.cache (it's a directory, not a file.
15926 * Makefile.am: Ditto (but maintainer-clean-local).
15928 2001-08-15 Akim Demaille <akim@epita.fr>
15930 * bin/autom4te.in (@m4_warning): New.
15931 (&handle_m4): Use it.
15932 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15933 warnings are issued at each run.
15934 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15935 is in the src tree.
15937 2001-08-15 Akim Demaille <akim@epita.fr>

15940 don't waste time running `autoupdate --version' works.
15941 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15943 2001-08-13 Akim Demaille <akim@epita.fr>
15945 * doc/autoconf.texi (ma): Rename this index as...
15946 (ac): this.

15968 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
15969 to the INSTALL file.

15996 * tests/mktests.sh: Update year in copyright notice.
15998 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
16000 * tests/semantics.at (AC_C_BIGENDIAN): New test.
16002 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
16004 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
16005 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
16006 * doc/autoconf.texi (C Compiler Characteristics): Update
16007 documentation for AC_C_BIGENDIAN.
16009 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
16011 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
16012 magic values from an object file when cross-compiling.
16013 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
16015 2001-08-10 Akim Demaille <akim@epita.fr>
16017 * bin/autom4te.in (&handle_output): Don't use `grep' with side
16018 effects.
16019 Suggested by Russ Allbery.
16021 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
16023 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
16024 current $prefix to the sub-configures.
16026 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
16028 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
16029 extension (needed on BeOS). Reported by Guido van Rossum.
16031 2001-08-09 Akim Demaille <akim@epita.fr>
16033 * bin/autom4te.in ($icache): Load it only if older than autom4te.
16035 2001-08-07 Akim Demaille <akim@epita.fr>
16037 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
16038 removed.
16039 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
16040 No need to remove the files before and after the each test, before
16041 each test and at the end of the suite is enough.
16042 Display only the children `times', not the shell's.
16043 If the test failed or was skipped, at-times is not available.
16045 2001-08-07 Akim Demaille <akim@epita.fr>
16047 Always produce testsuite.log, including when there are no
16048 failures. This helps getting information on skipped tests, and
16049 duration of the tests. Err, implement the latter btw.
16051 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
16052 Dump information on the first run of each test.
16053 (AT_CLEANUP): Create `at-times' containing the duration of the
16054 test group.
16056 2001-08-07 Akim Demaille <akim@epita.fr>
16058 The use of `dumpstat' revealed that `len' was used although it
16059 should not. m4_text_wrap was using it, but in the Autoconf world
16060 where it is legal. Hence (i) test M4sh in its own world, not
16061 Autoconf's, and (ii), ahem, fix the bug :)
16063 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
16064 does not like `' instead of [].
16065 (AT_INIT): Forbid `^_?AT_'.
16066 And don't output such tokens.
16067 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
16068 `script.as', and `autom4te.cache'.
16069 Remove `empty' and `macro' which are no longer used.
16070 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
16071 * tests/m4sugar.at: Use it.
16072 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
16074 2001-08-07 Akim Demaille <akim@epita.fr>
16076 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
16078 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
16080 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
16082 2001-08-04 Akim Demaille <akim@epita.fr>
16084 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
16085 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
16086 AC_TRY_LINK.
16087 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
16088 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
16089 (AC_F77_MAIN): Likewise.
16091 2001-08-04 Akim Demaille <akim@epita.fr>
16093 Don't rely on M4sugar outputting the patterns in files, since we
16094 might process the output _without_ running m4, hence without these
16095 files.
16097 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
16098 * bin/autom4te.in (@Request::includes): Remove, unused.
16099 (@Request::source): Rename as...

16662 cross-language link tests can be performed successfully.
