1947 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1948 check_SCRIPTS. Building the wrappers for `all' allows help2man
1949 to use them for the manpages.
1950 Report by Benoit Sigoure.
1952 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1954 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1956 Fix some write failure cases in Autotest.
1957 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
1958 upon write failures for --help, --version, --list.
1959 Guard against write failures for intermediate created scripts.
1960 <at_func_create_debugging_script>: Do not make the debugging
1961 script executable if it is not complete.
1963 2007-12-12 Eric Blake <ebb9@byu.net>
1965 Fix thinko in earlier patch - m4_join isn't defined yet.
1966 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1967 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1968 (m4_require): Use m4_do, not m4_join.
1970 Fix some whitespace tests on cygwin.
1971 * tests/tools.at (autom4te and whitespace in file names): Restore
1972 font-lock. Create $TMPDIR before it might be used.
1974 Fix spurious testsuite failure with M4 1.4.11.
1975 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1977 Optimize AC_REQUIRE.
1978 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1979 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1980 (m4_require): Avoid extra macro calls.
1982 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1984 * tests/torture.at (srcdir): Fix quoting.
1986 Do not pass top_srcdir to configure scripts in testsuite.
1987 * tests/autotest.at (srcdir propagation): Copy install-sh to
1988 source tree.
1989 (my only test): Drop setting of `top_srcdir'.
1990 * tests/base.at (Input/Output): Likewise.
1991 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1992 config.guess, and config.sub to test source tree.
1993 Drop AC_CONFIG_AUX_DIR setting.
1994 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1995 * tests/torture.at (Substitute a 2000-byte string): Drop
1996 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1997 (Substitute a newline, datarootdir workaround): Likewise.
1998 (Define a newline): Adjust for linenumber changes in configure.ac.
1999 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
2001 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
2002 if `pwd` contains whitespace.
2004 Quote $abs_top_srcdir in tests.
2005 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
2006 * tests/tools.at (Syntax of the shell scripts): Likewise.
2008 * tests/m4sh.at (LINENO): Quote $0.
2010 Fix testsuite program wrapper for whitespace in `pwd`.
2011 The problem here is that the usual mantra is that command
2012 variables can contain arguments, thus we cannot just escape
2013 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
2014 $top_builddir/tests directory early in $PATH, so that the
2015 wrappers are found by their plain name.
2016 * tests/wrapper.as: Put $testdir early in $PATH.
2017 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
2019 Proper config.status --file/--header and $srcdir escaping.
2020 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
2021 characters in $ac_file_inputs.
2022 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
2023 accordingly.
2024 * tests/torture.at (datarootdir workaround): Adjust.
2025 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
2027 Fix Autotest for whitespace in `pwd`.
2028 * lib/autotest/general.m4 (AT_INIT)
2029 <at_func_create_debugging_script, Driver Loop>:
2030 Quote $at_group_dir.
2031 * tests/autotest.at (whitespace in absolute testdir): New test.
2033 * lib/autom4te.in: Quote @datadir@.
2035 Proper file name escaping in Autoconf programs and Perl modules.
2036 This includes escaping of characters special to the shell
2037 as well as special to Perl, e.g., leading `<' or `>'.
2038 For example, when $file starts with `>', `open ">$file"'
2039 wrongly tries to append to a different file.
2040 * bin/autoconf.as: Fix quoting for autom4te options.
2041 * lib/Autom4te/General.pm (shell_quote): New function, taken
2042 from coreutils, written by Jim Meyering.
2043 (mktmpdir): Use it.
2044 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
2045 and open_quote.
2046 * bin/autoreconf.in (parse_args): Likewise.
2047 * bin/autoscan.in (main): Likewise.
2048 * bin/autoupdate.in (main): Likewise.
2049 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
2050 * bin/ifnames.in: Likewise, XFile usage fixes.
2051 * tests/tools.at (autom4te and whitespace in file names): Extend
2052 test. Test twice, with special characters allowed on w32, and the
2053 rest. Test leading and trailing whitespace, for `open_quote'.
2054 (autotools and whitespace in file names): New, analogous test.
2055 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
2056 by Russ Allbery and Eric Blake.
2058 Sync from Automake.
2059 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
2060 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
2061 * lib/Autom4te/FileUtils.pm (open_quote): New function.
2062 (update_file, contents): Use it.
2064 * Makefile.am (autom4te-update): Rewrite for git.
2066 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2068 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
2070 Fix copyright years.
2071 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
2072 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
2074 2007-12-04 Eric Blake <ebb9@byu.net>
2076 Manually resync with gnulib, since 'make cvs-update' no longer works.
2077 * build-aux/config.guess: New upstream version.
2078 * build-aux/config.sub: Likewise.
2080 When using older automake, don't downgrade build-aux/texinfo.tex.
2081 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
2082 * doc/Makefile.am (TEXINFO_TEX): Add.
2084 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2086 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2087 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2088 #undef as this runs afoul of our new way of creating config.h.
2089 Problem reported by Jim Meyering in
2090 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2092 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2094 Fix autom4te for unusual characters in input file names.
2095 * bin/autom4te.in (files_to_options): Quote active characters
2096 for the shell.
2097 * tests/tools.at (autom4te and white space in file names):
2098 New test.
2100 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2101 Document that Tru64 awk always splits $0.
2103 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2105 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2106 `#AT_STOP_...' line at the end of each test.
2108 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2110 * lib/autotest/general.m4 (AT_INIT): For awk line number
2111 extraction script, ensure `$at_group' has a defined value
2112 even for the empty set, and properly quote its usage inside
2113 the awk script.
2115 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2117 * doc/autoconf.texi (Shell Functions): New chapter. Document
2118 IRIX sh $0 issue in functions, move content from ...
2119 (Portable Shell): ... here.
2120 (Shell Script Compiler): Note that shell functions are not
2121 totally unportable any more.
2123 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2124 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2126 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2127 extracting the line numbers of the last needed test.
2129 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2131 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2132 Fix quoting.
2134 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2136 Fix IRIX testsuite debugging failures: $0 in functions.
2137 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2138 Do not use $0 inside a function, as IRIX sh will set that to the
2139 function name rather than the script invocation name.
2141 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2142 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2144 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2145 to extract test scripts.
2146 (AT_INIT): Extract and cache test script line numbers.
2148 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2150 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2151 subsequent fixups; the awk -> here-document conversion trashes
2152 performance too much with AIX sh.
2154 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2156 * tests/local.at: Do not test m4, perl with AT_TESTED.
2158 Diagnose and guard against write errors dealing with config.status.
2159 The general idea is this: all write failures from `configure'
2160 writing `config.status' are indicated by $ac_write_error, which
2161 is only checked at the end. This is safe because config.status
2162 code is not executed before the file is complete. Other write
2163 failures, be they inside config.status, or in sub shell/awk
2164 scripts spawned from configure or config.status, typically need
2165 earlier checking, as their results are used right afterwards.
2166 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2167 before writing config.status, check afterwards.
2168 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2169 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2170 Set `ac_write_error' for write failures to config.status. Barf
2171 upon write failures to temporary files.
2172 Adjust note about closing and reopening the here-document.
2173 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2174 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2175 reopening the here-document.
2176 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2177 Ensure `ac_write_error' does not escape into config.status.
2178 Also, add a couple of code paths not yet exercised in the test
2179 suite: a config file with input from stdin, and a config header
2180 output to stdout.
2181 Suggestion for catching write errors by Bruno Haible.
2183 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2185 Avoid error with Tru64 awk and testsuite lines with many words.
2186 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2187 reads the testsuite, set the field separator to an unusual value,
2188 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2189 even splits the input if $i, i>0, was never accessed in the script.
2191 Revert 2007-10-17 change.
2192 * TODO: Multiline args in config files and headers mean something
2193 different and are not fixed, see
2194 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2195 Report by Stepan Kasal.
2197 * doc/autoconf.texi (Generic Programs): Fix typo.
2199 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2201 AC_*_TOOL does not canonicalize the prefix
2202 * doc/autoconf.texi (Generic Programs): Do not say that
2203 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2205 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2207 Diagnose write errors in config.status instantiations.
2208 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2209 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2210 on write errors.
2211 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2212 Extend test to also check for some write error failures, using...
2213 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2214 Report by Bruno Haible.
2216 Indentation fixups.
2217 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2218 indentation.
2219 (_AT_CHECK): Use less indentation, to save space.
2221 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2223 Add witness macro for @top_build_prefix@ substitution.
2224 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2225 (_AC_OUTPUT_FILE): Mention it here.
2227 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2228 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2230 * lib/autotest/general.m4 (at_func_test): Remove.
2231 (AT_INIT): Pre-extract test groups into separate files.
2232 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2233 Remove at-test-source files together with the $at_group_dir.
2234 * tests/autotest.at (Long test source lines): New test.
2236 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2238 Shell functions and variables may share a namespace.
2239 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2240 limitation.
2242 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2244 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2245 gnulib.
2247 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2249 * lib/autoconf/status.m4: Fix a couple of comment typos.
2251 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2253 2007-11-13 Jim Meyering <meyering@redhat.com>
2255 Clean up the rule to create "expr".
2256 * tests/Makefile.am (expr): Don't redirect directly to target.
2257 Redirect just once, not for each echo statement.
2258 Use $@, not literal "expr".
2260 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2262 Don't worry about preprocessor when testing long long.
2263 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2264 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2265 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2266 These no longer check for preprocessor flaws.
2267 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2268 Do not check for preprocessor flaws.
2270 2007-11-13 Jim Meyering <meyering@redhat.com>
2272 Adapt dependencies, now that a version change doesn't modify configure.ac
2273 * GNUmakefile: Remove "make clean" kludge.
2274 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2275 configure.ac.
2276 Don't redirect directly to target.
2277 Use $@, not literal "version.m4".
2279 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2281 * doc/autoconf.texi (Making testsuite Scripts): Document
2282 ":;{" shorthand as in previous patch.
2284 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2286 * doc/autoconf.texi (Limitations of Builtins): Document problem
2287 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2288 for the workaround.
2289 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2290 Use ":;{" shorthand.
2291 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2293 2007-11-12 Jim Meyering <meyering@redhat.com>
2295 Add more non-srcdir build support.
2296 * GNUmakefile (dummy): Split a long line.
2297 Add -v option to autoreconf invocation.
2299 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2300 * GNUmakefile (dummy): Remove INSTALL.
2302 Remove racy commands to build scripts in bin/ and tests/.
2303 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2304 are guaranteed to be built, remove the rules that tried to build
2305 them. Before, with a parallel build, these rules could lead to
2306 two processes writing tests/wrapper.in concurrently.
2308 Build in man/ only *after* building in bin/ and tests/.
2309 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2310 in both bin/ and tests/.
2312 Accommodate non-srcdir build-from-checkout.
2313 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2314 Use git's --git-dir=$srcdir/.git option.
2315 Add quotes, in case tarball_version_file contains shell meta-characters.
2316 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2317 * configure.ac: Pass "." to git-version-gen.
2319 Avoid spurious test failures due to version skew.
2320 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2322 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2324 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2325 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):

2327 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2328 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):

2331 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2332 Likewise.
2333 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.

2347 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2349 Ignore configure --help* errors due to LINENO-impaired shells.
2350 * tests/torture.at (Configuring subdirectories, Deep Package):
2351 In the --help* tests in read-only trees, make `.' temporarily
2352 writable again for the `stderr' file, and ignore errors due to
2353 the attempt to write configure.lineno.
2354 Report by Patrick Welche.
2356 2007-11-10 Jim Meyering <meyering@redhat.com>
2358 Generate package.m4 in build-dir, not srcdir.
2359 * tests/Makefile.am (package.m4): Adjust target.
2360 Don't redirect directly to $@.
2361 (CLEANFILES): Add package.m4.
2362 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2363 in $(srcdir).
2364 When running $(AUTOTEST), search "." before searching $(srcdir).
2366 Avoid a race condition that would make parallel "distclean" fail.
2367 * tests/Makefile.am (distclean-generic): Replace the default,
2368 automake-provided rule with an identical one, but with an additional
2369 dependency on distclean-local. Simply adding the dependency would
2370 cause automake not to emit the rule at all.
2371 * BUGS: Building with -jN works, now.
2373 Distribute git-version-gen.
2374 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2375 since GNUmakefile is distributed, and requires it for dist* rules.
2377 Remove two more generated files from version control.
2378 * INSTALL: Remove generated file.
2379 * lib/autoscan/autoscan.list: Remove generated file.
2381 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2383 * GNUmakefile (PATH): Remove stray apostrophes; they become
2384 part of PATH, which isn't wanted here.
2386 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2388 New config files output variable `top_build_prefix'.
2389 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2390 `top_build_prefix'.
2391 * doc/autoconf.texi (Preset Output Variables): Document it.
2392 * NEWS: Update.
2393 Report by Bob Friesenhahn.
2395 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2396 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2397 function, to parametrize arithmetic with expr vs. the shell.
2398 Use it where possible.
2399 Suggestion by Benoit Sigoure.
2401 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2403 Adjust the documentation of autotest WRT atlocal.
2404 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2405 when using Automake, to write a rule to produce atlocal, since it's
2406 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2407 distributed, not atconfig.in.
2409 2007-11-04 Eric Blake <ebb9@byu.net>
2411 Update list information.
2412 * README: Mention new autoconf-commit list.

2508 Make inter-release --version output more useful.
2510 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2511 which indicates that it is built using the 19th change set
2512 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2513 is a prefix of the commit SHA1.
2514 * build-aux/git-version-gen: New file.

2595 configure script to be found in $PATH, if the shell does not do
2596 this resolution. Fixes test failure on FreeBSD.
2598 Fix config header generation with AIX awk.
2599 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk

3781 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

3801 for C++; this drops support for anonymous struct and union types,
3802 which were problematic anyway.
3803 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even

3819 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
3820 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
3821 with objects too. Document the restrictions on its use.
3822 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3823 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3824 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3825 works but the latter doesn't, then it's a valid type.
3826 This lets people use function types and so forth.
3827 For C++ there doesn't seem to be a simple solution, so leave it alone.
3828 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3829 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3830 AC_CHECK_TYPE; that wasn't documented or necessary.
3832 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3834 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3889 HP-UX's grep, like the one from Solaris, does not support that syntax.
3891 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3893 * doc/autoconf.texi (Specifying Names): `--host' does not
3894 change the build type.
3896 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3898 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3899 suggests AC_CONFIG_HEADERS.

3998 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4000 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
4001 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
4002 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
4003 substitution will still be done by the special code.
4004 Report by Jim Meyering.

4021 2007-01-15 Stepan Kasal <kasal@ucw.cz>
4023 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
4025 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4027 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
4028 early on the reader side, drop stderr of the input to avoid
4029 `broken pipe' error output; this may happen even with shell
4030 builtin `echo' of some bash versions. Reports by Ian Macdonald
4031 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
4033 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4035 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
4036 separate items of `ac_user_opts', to avoid long lines.
4037 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.

4043 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
4045 Fix some wording problems noted by Paolo Bonzini in:
4046 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
4047 * doc/autoconf.texi (Signed Overflow Examples): Give more
4048 discussion about the allow_superuser_privileges example,
4049 and change it a bit to make things clearer.
4050 (Optimization and Wraparound): Clarify whether the compiler
4051 will generate an infinite loop for the example derived from
4052 Autoconf's mktime test.
4053 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
4054 Also, clarify unsigned multiplication overflow.
4056 2007-01-04 Eric Blake <ebb9@byu.net>
4058 * bin/Makefile.am (RELEASE_YEAR): New macro.
4059 (edit): Use it to supply correct copyright year to scripts.
4060 * bin/autoconf.as (version): Use it.
4061 * bin/autoheader.in ($version): Likewise.
4062 * bin/autom4te.in ($version): Likewise.
4063 * bin/autoreconf.in ($version): Likewise.
4064 * bin/autoscan.in ($version): Likewise.
4065 * bin/autoupdate.in ($version): Likewise.
4066 * bin/ifnames.in ($version): Likewise.
4068 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4070 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4071 feedback. The most important changes document what happens when
4072 you convert an out-of-range value to a signed integer type, and
4073 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4074 a + b.
4076 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4077 rewrite, taking notions from the recent discussion on the gcc and
4078 autoconf mailing lists; please see
4079 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4080 and follow the many links.
4081 (Integer Overflow Basics, Signed Overflow Examples):
4082 (Optimization and Wraparound, Signed Overflow Advice):
4083 (Signed Integer Division): New sections.
4085 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4087 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4088 preprocessor macro arguments in traced name.
4089 * doc/autoconf.texi (Defining symbols): Document longstanding
4090 support for AC_DEFINE-ing macros with arguments, and document
4091 behavior when the same variable has multiple AC_DEFINEs.
4092 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4093 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4094 macros directly, giving much shorter and simpler code.
4096 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4098 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4099 space before "$ac_configure_args" to prevent a 'config.status
4100 --recheck' failure if ac_configure_args doesn't contain a leading
4101 space. This works around a problem with the XEmacs configure.ac,
4102 which uses the (undocumented) ac_configure_args variable
4103 inconsistently with Autoconf.
4105 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4107 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4108 Include <limits.h>, and use its INT_MAX to rewrite the
4109 j loop so that it does not overflow 'int'. Problem reported by
4110 Ralf Wildenhues in
4111 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4112 Play it safe by shifting left by 1 rather than multiplying by 2,
4113 as GCC is less likely to optimize this away when the value
4114 is signed (when it assumes overflow leads to undefined behavior).
4115 Also, don't assume time_t uses two's complement.
4117 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4119 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4120 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4121 dumps core on it. Report by Tim Rice.
4123 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4125 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4126 --disable-option-checking to --help output even when
4127 AC_PRESERVE_HELP_ORDER is not used.
4128 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4129 --with argument, rather than argument with [-.] replaced by
4130 underscores.
4131 * NEWS: Fix typo in previous change; the news was in the
4132 wrong section.
4134 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4136 * NEWS: Warnings are now generated by default for unknown
4137 --enable-* and --with-* options.
4138 * doc/autoconf.texi (Option Checking): Renamed from
4139 (Configure Option Checking). Tighten up the wording a bit.
4140 (External Software, Package Options): Cross-reference to Option
4141 Checking, and use this to shorten our section.
4142 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4143 "$x" to test "x$foo" != x.
4144 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4145 Don't warn if $enable_option_checking is "no".
4146 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4147 ac_unrecognized_opts to the empty string.
4148 Don't echo the unrecognized opts, as this might mishandle
4149 backslashes or leading -.
4150 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4151 usage next to the other --disable-FEATURE options in the
4152 help string.
4154 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4156 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4157 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4158 Print warning for unrecognized --with and --enable options
4159 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4160 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4161 Disable option checking when subdirs are configured.
4162 (AC_OUTPUT): If warnings are enabled, print warning about
4163 unrecognized --with and --enable options at the end of
4164 the configure output (as well as at the beginning).
4165 * doc/autoconf.texi (Option Checking): New node.
4166 Document new option warning functionality.
4168 2006-12-16 Eric Blake <ebb9@byu.net>
4170 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4171 * NEWS: Start news for current version.
4173 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4175 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4176 Define HAVE_GETMNTENT to 1, not to the empty string.
4177 Problem originally reported by Jochen Friedrich in
4178 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4180 This change prompted by a problem report by Andrey Simonenko in
4181 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4182 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4183 object-like macros only, in the traditional portable character
4184 set.
4185 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4186 Warn about attempts to define things that are not identifiers.
4187 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4188 awful hack that AC_DEFINEd macro names containing parentheses.
4190 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4192 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4193 too drastic, even if Texinfo in theory requires it for info mode.
4195 (config.status Invocation): Renamed back from Recreating a
4196 Configuration).
4197 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4198 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4200 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4202 * NEWS: Version 2.61a.
4204 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4205 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4207 * NEWS: Document changes with echo and printf, and the lack
4208 of limits on the total size of multi-line values of substituted
4209 variables, and the AC_FUNC_FSEEKO fix.
4211 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4213 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4214 Writing configure.ac.
4215 (Autoconf Input Layout): Renamed from configure.ac Layout.
4216 (Recreating a Configuration): Renamed from config.status Invocation.
4217 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4218 (acconfig Header): Renamed from acconfig.h.
4219 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4220 (Writing Testsuites): Renamed from Writing testsuite.at.
4221 (Autom4te Cache): Renamed from autom4te.cache.
4223 * BUGS: Remove mention of VPATH problem, since it's now documented
4224 not to be a bug in the Autoconf build procedure itself, but rather
4225 a problem with the proprietary `make' programs.
4227 * doc/autoconf.texi (Build Directories): Add a cross reference
4228 to VPATH and Make.
4230 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4231 * doc/standards.texi: Sync from gnulib.
4233 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4234 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4235 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4236 generated automatically.
4238 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4240 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4241 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4242 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4244 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4246 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4247 `CEOF$ac_eof' special marker, the awk script cannot contain a
4248 line matching `^CEOF', so this is not needed any more.
4249 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4250 special marker in the test.
4252 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4254 * tests/tools.at (autom4te preselections): Use `find -newer';
4255 remove one of the sleeps.
4257 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4258 more readable, using ...
4259 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4261 * doc/autoconf.texi (autoheader Invocation): Do not double-
4262 quote the parameter of `AH_BOTTOM' in the example.
4264 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4266 * doc/autoconf.texi (Configuration Headers): Remove the
4267 example with multiple input files.
4268 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4269 multiple input files.
4271 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4273 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4274 creating the awk substitution script, handle one input line at a
4275 time, so that the maximum length of a substituted (multi-line)
4276 value is not limited by the size of the sed pattern space.
4277 The trade-off is a slightly repetitive sed script.
4278 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4279 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4280 * tests/torture.at (Substitute a 2000-byte string): Increase the
4281 test with several long lines, they should not be caught by sed
4282 limits any more.
4284 * tests/tools.at (autom4te preselections): New test, to flag
4285 entries missing from autom4te.cfg.
4286 Report by David Byron <dbyron@hheld.com>.
4288 * tests/torture.at (Substitute a 2000-byte string): Actually use
4289 AC_PROG_AWK, so the last change works as intended.
4290 (Substitute and define special characters): Likewise.
4291 (Substitute a newline): Likewise.
4293 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4294 instead of `awk' consistently.
4295 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4296 * tests/torture.at (Torturing config.status): Test both the
4297 result of AC_PROG_AWK and plain awk.
4298 (Substitute a 2000-byte string): Likewise.
4299 (Substitute and define special characters): Likewise.
4300 (Substitute a newline): Likewise.
4302 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4304 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4305 can be assigned to a function pointer. Problem reported by
4306 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4307 part of a patch by Ralf Wildenhues in that same bug report.
4309 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4311 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4312 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4314 2006-12-01 Eric Blake <ebb9@byu.net>
4316 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4317 cross-compiling from cygwin to mingw.
4318 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4319 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4320 to lib/autoconf/c.m4.
4322 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4324 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4325 string for more reliable failure. Wrap the entire test that
4326 causes the broken Solaris printf to dump core, in a subshell,
4327 so the segmentation fault message is reliably suppressed.
4328 Fix shell expansion errors by using /usr/ucb/echo always;
4329 avoid an error on systems without it by another subshell.
4330 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4331 subshell-$as_echo to `as_echo', for better error message.
4333 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4335 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4336 `BASH_SOURCE' contain a newline, set them to empty, as they may
4337 not be unset.
4339 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4341 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4342 years and is too hard to maintain now. The last straw was
4343 reported by Jerker Baeck in
4344 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4345 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4346 * doc/autoconf.texi (Particular Functions): Move
4347 AC_FUNC_SETVBUF_REVERSED from here...
4348 (Obsolete Macros): ... to here. Say that it does nothing now.
4349 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4350 Turn into (almost) a no-op.
4352 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4353 (AC_C_VOLATILE):
4354 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4355 These macros are obsolescent and new applications shouldn't need them.
4356 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4357 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4358 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4359 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4360 (AC_FUNC_VPRINTF): Likewise.
4361 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4362 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4363 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4365 * doc/autoconf.texi (Setting Output Variables): Mention that
4366 @VAR1@VAR2 has unspecified behavior. Problem reported by
4367 Ralf Wildenhues.
4368 * NEWS: Mention this.
4370 * Makefile.am: Put only a single '#' into the copyright notice,
4371 so that it's also present in the output file. Standardize wording
4372 in makefile copyright notices to match GNU coding standards.
4373 * bin/Makefile.am: Likewise.
4374 * doc/Makefile.am: Likewise.
4375 * lib/Makefile.am: Likewise.
4376 * lib/freeze.mk: Likewise.
4377 * lib/autoconf/Makefile.am: Likewise.
4378 * lib/autoscan/Makefile.am: Likewise.
4379 * lib/autotest/Makefile.am: Likewise.
4380 * lib/m4sugar/Makefile.am: Likewise.
4381 * man/Makefile.am: Likewise.
4382 * tests/Makefile.am: Likewise.
4383 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4384 one-line file.
4386 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4388 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4389 in the sed script that mangles the awk script: delete up to the
4390 first exclamation mark only.
4391 * tests/torture.at (Substitute and define special characters):
4392 Test '!' too.
4394 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4396 Rewrite config files generation: avoid quadratic growth in
4397 the number of substituted variables by using awk instead of sed
4398 for the bulk of the substitutions.
4399 * NEWS: Mention this.
4400 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4401 forbidden in the output (and thus input) file.
4402 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4403 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4404 generate just one large awk script for substitutions,
4405 eliminating much of the earlier complexity, while adding some
4406 new complexity. Only expand the substitution templates at
4407 configure time, for smaller configure script size. If
4408 _AC_SUBST_FILES are used, test 'awk' for working getline support
4409 at config.status time. If absent, interpolate through the
4410 shell. The awk script was written with much help
4411 from Paolo Bonzini and Paul Eggert.
4412 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4413 (_AC_SED_FRAG_NUM): Likewise.
4414 (_AC_SUBST_CMDS): Renamed from...
4415 (_AC_SED_CMDS): ...this.
4416 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4417 * tests/torture.at (Substitute a 2000-byte string): Also
4418 substitute a line with 1000 words, and a variable with several
4419 long lines.
4420 (Substitute and define special characters): Test awk special
4421 characters, and put substitution input strings `@foo@' in the
4422 output, to test that no recursion happens; test several other
4423 combinations from Paolo Bonzini.
4425 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4427 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4428 that replaced echo with AS_ECHO where this wasn't necessary.
4429 Problem reportd by Ralf Wildenhues.
4430 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4431 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4432 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4434 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4436 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4438 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4440 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4441 that traditional Awk lacks 3-arg "split". It has it.
4442 Mention that FS must be a single character, and a few other
4443 99-byte limits of traditional Awk.
4444 Mention that if (i in a) doesn't work with traditional Awk.
4446 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4448 * tests/autotest.at (BSx641-newline in command):
4449 (BS-BS-newline in command, BSx640-newline in command):
4450 (Newline-CODE-BS-newline in command):
4451 (Single-quote-BS-newline in command):
4452 (Single-quote-newline-BS-newline in command):
4453 Use printf '%s\n' instead of echo, for portability to hosts
4454 where echo interprets backslashes. This will break on hosts
4455 that lack printf, but for now let's assume all such hosts
4456 are dead (if not, we should get reports of test failures).
4458 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4460 'echo' has some portability problems, when given a first argument
4461 with a leading '-', or when given any argument containing '\'.
4462 Avoid using 'echo' in these cases.
4463 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4464 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4465 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4466 * lib/autotest/general.m4 (AT_INIT): Likewise.
4467 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4468 argument might be unportable.

4470 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

4474 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):

4487 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4488 * bin/autoconf.as: Redo verbose flag implementation, as the old
4489 scheme wouldn't work with AS_ECHO.
4490 * lib/autotest/general.m4 (AT_INIT): Likewise.
4491 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4492 Don't use ECHO_T, since ECHO_N is now reliable.
4493 * lib/autotest/general.m4 (AT_INIT): Likewise.
4494 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4495 rather than using a here-document to put the script into a file.
4496 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4497 use AS_ECHO.
4498 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4499 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4500 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4501 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4502 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4503 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4504 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4505 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4506 operand, as AS_ECHO requires. Avoid double file name expansion.
4507 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4508 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4509 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4510 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4511 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4512 Double-quote strings that would otherwise contain M4 comments.
4513 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4515 * configure.ac (AC_INIT): Bump to 2.61a.
4516 * NEWS: Likewise.
4518 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4520 Version 2.61.
4522 * configure.ac (AC_INIT): Bump to 2.61.
4523 * NEWS: Likewise.
4525 * tests/autotest.at (Macro with backslash in a test title):
4526 Comment out for now, as this tests neither fails nor passes
4527 reliably. Problem reported by Ralf Wildenhues.
4529 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4531 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4532 in previous change, which caused test failures.
4534 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4536 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4537 code for --enable, --disable, --with, and --without to...
4538 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4539 * doc/autoconf.texi (Package Options):
4540 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4542 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4544 Import these changes from config via gnulib:
4546 2006-11-15 Ben Elliston <bje@gnu.org>
4548 From Josselin Mouette <joss@debian.org>:

4576 Both of these suggestions from Eugene Y. Vasserman.
4579 Import these changes from texinfo via gnulib:
4581 2006-11-08 Karl Berry <karl@gnu.org>
4583 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and

4585 no further ado.
4587 2006-11-05 Karl Berry <karl@gnu.org>
4589 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

4601 first argument may also contain dots.
4603 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4605 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4606 benefit of platforms like Solaris+GCC where it is common to have a
4607 non-working g++ installation.
4609 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4610 and Joel E. Denny <jdenny@ces.clemson.edu>
4611 and Paul Eggert <eggert@cs.ucla.edu>
4613 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4614 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4615 ./micro-suite.
4617 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4619 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4620 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4621 Imported from a similar patch to gnulib by Bruno Haible.
4623 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4625 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4633 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
4634 Matthew Woehlke.
4636 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4638 * tests/torture.at (Configuring subdirectories): Do not skip
4639 Automake 1.10 nor future Automake 11.1 (sic).
4641 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4642 and Stepan Kasal <kasal@ucw.cz>
4644 Handle special characters in test case titles correctly.
4645 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4646 properly.
4647 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4648 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4649 argument. Extend to check titles printed by ./micro-suite and
4650 ./micro-suite -l and the title in micro-suite.log.
4651 (Backquote in a test title,
4652 Single-quote in a test title,
4653 Double-quote in a test title): Don't expect failure anymore.
4654 (Backslash in a test title): Put a non-whitespace character after the
4655 backslash so that Bourne shells might actually see it as an escape
4656 sequence.
4657 (Brackets in a test title,
4658 Pound in a test title,
4659 Comma in a test title,
4660 Quoted Macro in a test title,
4661 Macro in a test title,
4662 Macro with single-quote in a test title): New tests.
4663 (Macro with backquote in a test title,
4664 Macro with double-quote in a test title,
4665 Macro with backslash in a test title): New tests expected to fail.
4666 * tests/torture.at (#define header templates): M4-quote this title in
4667 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4668 The visible effect was a stray [] in the testsuite output.
4670 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4672 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4673 `trap ... 0' inside a function, for AIX sh.
4675 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4677 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4678 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4679 5363) simply issues a warning when dividing by zero at compile
4680 time. Problem reported by Elias Pipping.
4682 2006-10-26 Eric Blake <ebb9@byu.net>
4684 * THANKS: Update.
4685 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4686 show effect on macros that expand with commas.
4687 Reported by Joel E. Denny.
4689 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
4690 Also work with M4 1.4.8.
4692 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
4694 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
4695 Jim Meyering.
4697 2006-10-25 Stepan Kasal <kasal@ucw.cz>
4699 * tests/tools.at (autom4te --force): New test, verifies that
4700 `--force' always rewrites the output file.
4702 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4704 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
4705 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
4707 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4709 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
4711 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4713 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4714 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4715 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4716 reported by Nelson H. F. Beebe for Coreutils 6.4.
4718 * tests/tools.at (autoconf --trace: user macros): Remove test
4719 for tracing multiline macros, since m4 1.4.7a uses a different
4720 way to number lines. Problem reported by Ralf Wildenhues.
4722 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4724 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4725 /dev/null since the heuristics for interactive behaviour was
4726 fixed in CVS m4.
4728 * bin/autom4te.in: With --force, always refresh the output
4729 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4731 * bin/autoconf.as: Fix the verbose message at the end.
4733 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4748 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4749 AC_CACHE_CHECK_INT, since it's no longer public.
4750 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4751 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4753 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4755 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
4757 2006-10-19 Eric Blake <ebb9@byu.net>

4779 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4781 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4782 looking for special shell characters.
4783 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4784 macro defined by AS_VAR_PUSHDEF before passing it as a
4785 parameter.
4786 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
4787 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

4796 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4798 (Imported from Automake.)
4799 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4800 which incorrectly sets the mode of an existing destination
4801 directory. In some cases the unpatched install-sh could do the
4802 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4803 system. We hope this is rare in practice, but it's clearly worth
4804 fixing. Problem reported by Alex Unleashed in
4805 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4806 Also, don't bother to check for -m bugs unless we're using -m;
4807 suggested by Stepan Kasal.
4809 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4811 Import this change from Automake:
4813 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

4815 is enabled by default with gnu and gnits strictness.
4816 Report from Bruno Haible.
4818 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4820 gnu and gnits modes.
4822 Import this change from Config:
4824 2006-09-20 Ben Elliston <bje@gnu.org>

4827 Import this change from Gnulib:
4829 2006-09-16 Karl Berry <karl@gnu.org>
4830 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,

4853 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4855 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4856 added to the template can get mangled.
4858 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4860 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4861 include the default headers, and redefine obstack_chunk_alloc
4862 and obstack_chunk_free. Fixes false failure with glibc.
4864 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4866 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

4868 by Ralf Wildenhues.
4870 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4872 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4873 AC_PROG_CC.

4876 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4878 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4879 the NonStop platform.
4880 * doc/autoconf.texi (Posix Variants): Likewise.
4881 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4883 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4884 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4885 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4886 Use a better substitute, by inspecting the output of "ls"
4887 rather than just using ":".
4888 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4889 rather than AS_EXECUTABLE_P, since we needn't worry about
4890 non-regular files here.
4892 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4893 due to configuration hassles with this. See Tonya Underwood's report
4894 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4895 * doc/autoconf.texi (Special Shell Variables): Likewise.
4897 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

4901 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4903 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4905 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4906 initialization which is not inherited through the environment
4907 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4908 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4910 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4912 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4913 problems with mkdir -p -m.
4915 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4917 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4918 comment about ac_cpp_err; it was incorrect, and anyway
4919 ac_cpp_err is being removed below.
4920 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4921 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4922 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4923 nobody uses it.
4924 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4925 with werror_flag and conftest.err and so forth. This is more
4926 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4927 and anyway the user shouldn't normally want to see this gorp logged.
4928 Problem reported by Ralf Wildenhues.
4929 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4930 empty, not 'no', since the rest of the code uses 'test -z'.
4932 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4934 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4935 Use a single call to AC_DO_TOKENS rather than multiple, for
4936 efficiency.
4937 (_AC_LINK_IFELSE): Test that resulting file is executable.
4938 Problem reported by mwoehlke in
4939 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4941 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4942 than creating a file to use with test -x; this is much faster.
4944 2006-10-02 Bruno Haible <bruno@clisp.org>
4946 * lib/autom4te.in (Automake-preselections): Add
4947 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4949 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4951 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4952 standard error, `experr' should be used, not `expout'.
4954 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4956 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4957 fseeko testing program twice; just use the earlier result.
4958 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4959 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4960 still doesn't let the program compile.
4961 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4962 failed.
4964 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4965 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4966 include it, without including anything else.
4967 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4968 expressions.
4969 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4971 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4973 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4974 `error.h', and include it, for a `error_at_line' prototype.
4975 Use a nonempty format string in the link test.
4976 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4977 for a declaration of wait3.
4979 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4981 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4982 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4983 can apply to constants too, and that it checks for macro defns.
4984 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4985 and simply cast the identifier to void. This handles structure
4986 values. Problem reported by Ralf Wildenhues.
4987 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4989 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4991 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
4992 structure, and function symbols.
4994 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4996 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
4997 member.

5009 warnings (uninitialized value).
5010 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
5011 present.
5012 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

5042 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
5043 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
5044 --error-output, to avoid warnings with M4 2.0.
5046 2006-09-19 Stepan Kasal <kasal@ucw.cz>
5048 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
5049 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
5050 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.

5059 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
5060 mistaken comment: the path has to be relative; do not use
5061 the path at runtime.
5063 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5065 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

5069 for both changes.
5070 * doc/autoconf.texi (Setting Output Variables): Fix example to
5071 not show `--silent' being passed to a `configure' re-run.
5073 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5075 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
5076 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
5077 for the existence of the directory at configure-time. That's
5078 too late, anyway. Problem reported by Stefan Seefeld.
5080 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
5081 7.1.4 /usr/bin/posix/sh described by Tim Rice in
5082 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
5084 2006-09-11 Stepan Kasal <kasal@ucw.cz>
5086 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
5087 works with GNU M4 1.4.3 again; make the normalized form
5088 match the current m4 message; fix the description.
5089 * test/tools.at (autom4te cache): Adapt to the change.
5091 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
5093 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
5094 to catch glibc bug 2821
5095 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
5097 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
5098 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
5099 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
5100 assume C89.
5102 2006-09-08 Stepan Kasal <kasal@ucw.cz>
5104 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

5122 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
5123 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
5124 accept files with extension `.f'. For consistency, also prefer
5125 xlf over f77.
5126 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
5127 from last patch.

5147 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
5148 except the first two arguments are reversed.
5149 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
5150 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
5151 caches nor outputs a diagnostic. Suggested by Bruno Haible.
5152 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
5153 equivalent to the old AC_COMPUTE_INT.
5154 (AC_COMPUTE_INT): No longer caches or reports. New signature.
5155 All uses changed to AC_CACHE_CHECK_INT.
5156 * tests/base.at (AC_CACHE_CHECK_INT): New test.
5157 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
5159 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
5161 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
5162 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
5163 programs should use their Gnulib counterparts.
5164 * doc/autoconf.texi (Particular Functions): Likewise.
5165 (Macro Names, testsuite Invocation): Replace uses of these
5166 obsolete macros with uses of non-obsolete macros.

5197 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
5198 deal with LEXLIB.
5199 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
5200 didn't work if some values were cached but not others. Test for
5201 broken lex libraries like native ia64-hp-hpux11.22; see
5202 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
5203 work around the problem by preferring an empty LEXLIB to -lfl or
5204 -ll. Let the user set LEXLIB='' to indicate no library needed.
5206 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
5207 * README: Likewise.
5208 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

5309 * doc/autoconf.texi (Particular Programs): Mention that
5310 @INSTALL@ and @MKDIR_P@ may vary for different output files.
5311 Reported by Alexandre Duret-Lutz.
5313 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
5315 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
5316 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
5317 Bill Northcott in
5318 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
5320 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>

5331 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
5332 -Wundef -Werror". Problem reported by David Fang in
5333 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
5334 * doc/autoconf.texi (Header Templates, Default Includes):

5349 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
5350 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
5351 this.
5353 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
5355 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
5356 problems with arg script text that doesn't end in newline, and
5357 with '-e a...'. Problems reported by Ralf Wildenhues.
5359 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
5361 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
5362 check for libXt by a check for libX11.
5364 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5367 to last change.
5369 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5371 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
5372 --help' should mention that `--version' outputs configuration
5373 settings. Report by Bruno Haible.
5375 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
5377 Fix test suite failures reported by Pierre in
5378 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
5379 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
5380 the compiler created a file "b.out" when it didn't create anything
5381 at all.
5382 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
5383 Discard stderr too, when invoking the test script.
5385 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
5387 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
5388 in the restoring of the werror flag.
5390 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5392 * doc/autoconf.texi (Volatile Objects): Be even a little
5393 less skeptical about "volatile", after discussion with
5394 Bruno Haible on bug-gnulib.
5395 (Limitations of Usual Tools): Warn about sed stripping
5396 leading white space from text. From Bruno Haible.
5398 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5400 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5401 compiler complains about it, even if things works after the
5402 complaint. Problem reported by Peter O'Gorman.
5404 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5405 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5406 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5408 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5410 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5411 after -R regardless of host. Patrick Welche reports that this
5412 fixes things on NetBSD 3.99.
5414 * NEWS: Recommend M4 1.4.5.
5415 * README: Likewise.
5416 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
5417 * tests/tools.at (autom4te cache): Update wording of diagnostic
5418 to match M4 1.4.5.
5420 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5422 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5423 under AC_C_VOLATILE.
5424 (Volatile Objects): Be a little less skeptical about what
5425 "volatile" means. Derived from thoughts by Ben Pfaff in
5426 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5428 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5430 * doc/autoconf.texi: Fix some typos.
5432 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5434 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5435 more globally, since the 2006-06-30 patch didn't suffice. Problem
5436 reported by Keith Marshall. Also, don't bother with builddir2,
5437 since it shouldn't be needed any more.
5439 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5441 * doc/autoconf.texi (Generic compiler characteristics):
5442 Document AC_COMPUTE_INT. Fix wrong statements on Default
5443 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5445 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

5448 AC_COMPUTE_INT.
5450 * NEWS: Document change.
5452 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5454 * doc/autoconf.texi (Volatile Objects): New section.
5456 * NEWS: Document previous change.
5458 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5460 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5461 Require that long long int be at least 64 bits wide. C99 requires
5462 this and enough programs depend on it so we should check for it.
5463 Bruno Haible reports in
5464 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5465 that long long int is 32 bits wide with some nonstandard compilers.
5466 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5468 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5470 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5471 to a nonexistent file, so that we don't have to worry about
5472 a local site configuration that doesn't use /usr/local.
5473 Problem reported by Keith Marshall in
5474 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5476 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5478 * doc/autoconf.texi: Be more consistent about using @acronym with
5479 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5480 quite right (it talked about "OSF/Tru64", even though the
5481 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5482 and it even mentioned "OSF 4"!) and at this point there's little
5483 reason to talk about OSF any more, since it died in 1994.
5484 (Specific Compiler Characteristics): Simplify example of
5485 negative-size array.
5486 (File Descriptors): Reorder to make the text flow better.
5487 Remove joke about "appreciate the various levels"; I didn't get it.
5488 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5489 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5490 (File Descriptors, Limitations of Usual Tools):
5491 Tone down the advice against renaming or removing open files.
5492 (Limitations of Usual Tools): Add a new section, on 'rm'.
5494 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5496 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5497 -lXt in LIBS, idea from Karsten Hopp; this was due since
5498 this change:
5500 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5501 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5502 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5503 (which belong to Xt, not X itself). See Debian bug 327655.
5505 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5507 * configure.ac (AC_INIT): Bump to 2.60a.
5508 * NEWS: Update.
5510 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5512 Version 2.60.

5516 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5518 * config/texinfo.tex: Sync from upstream.
5520 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5521 quadrigraph correctly in traces.
5523 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5524 Fix typos.
5526 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5527 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5528 not defined.
5529 * doc/autoconf.texi (Changed Directory Variables): New node,
5530 to document the whole `datarootdir' business a bit better.
5531 * NEWS: Update.
5532 * tests/torture.at (datarootdir workaround): Extend test.
5533 Prompted by report by Alexandre Julliard.
5535 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5537 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5538 when using default mode of IBM C 6 for AIX. Problem and two-line
5539 fix reported by Larry Jones.
5541 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5543 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5544 about literal '${datarootdir}' if a definition is found in the
5545 output file.
5547 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5549 * NEWS: Use "M4" rather than "m4" when appropriate.
5550 Problem reported by Eric Blake.
5551 * doc/autoconf.texi: Likewise.
5552 Use @acronym around BSD, GCC, and GNU when appropriate.
5553 (Why GNU M4): Renamed from "Why GNU m4".
5554 (Redefined M4 Macros): Mention that Posix
5555 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5556 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5557 to int.
5559 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5561 * bin/autom4te.in (handle_output): Do not forbid the empty
5562 pattern.
5563 * tests/tools.at (autoconf: the empty token): New test.
5565 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5567 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5568 calls, so that we do not care whether they are LIFO or FIFO;
5569 in the m4_wrap, do not check which diversion is the topmost
5570 one, just check that the stack is balanced at the end.
5571 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5572 base diversion forever--pop the previous diversion before
5573 opening the new one; consequently, remove the m4_wrap call.
5574 * lib/autotest/general.m4 (AT_INIT): Likewise.
5575 * tests/m4sugar.at: Do not use
5576 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5578 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5579 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5581 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5582 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5583 Rework example of m4wrap token-pasting trouble so that it doesn't
5584 care whether it's LIFO or FIFO.
5585 Fix some "contrary to"s that are awkward in English.
5587 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5589 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5590 to `yes' instead of `int$1_t' if the type is found, for more
5591 consistent configure output (where $1 is the number of bits).
5592 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5593 Suggested by Bruno Haible.
5595 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5596 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5597 with system headers. Report by Bruno Haible.
5599 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5601 * config/config.guess, config/config.sub: Sync from upstream.
5603 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5604 in order to avoid picking up an older installed frozen m4sh.m4f.
5605 Besides an outdated shell startup, this could have been created
5606 by an earlier M4 version with incompatible frozen file format.
5608 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5610 * README: Recommend m4 1.4.4 instead of 1.4.3..
5611 * doc/autoconf.texi: Likewise.
5612 (Special Chars in Names): Say that $(.FOO) is portable, as
5613 suggested by Stepan Kasal.
5614 (Installation Directory Variables, Build Directories):
5615 (Automatic Remaking, Subdirectories, Fortran Compiler):
5616 (Making testsuite Scripts, Defining Directories):
5617 Quote variable usages better.
5618 (Making testsuite Scripts): Add clean-local rule to makefile
5619 snippet, by Eric Blake.
5620 (Installation Directory Variables): Fix table item font.
5621 Reword slightly to clarify. Generalize advice about
5622 not using special characters to include all file-related
5623 vars, not just VPATH.
5624 (Special Chars in Variables): Warn about special characters in
5625 $(srcdir) too.
5626 (Assignments): Clarify default-value example as suggested by
5627 Ralf Wildenhues in
5628 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5629 (Special Shell Variables): Note leading ./ or ../, as suggested
5630 by Eric Blake.
5631 (Limitations of Builtins): Under cd, warn about CDPATH.
5632 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5633 Ralf Wildenhues.
5635 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5637 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5638 `@var', for texi2html.
5639 (Systemology): Some more word wrapping, for DVI output.
5640 (autom4te Invocation): The short option for `--melt' is `-M',
5641 not `-m'.
5643 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5645 * doc/autoconf.texi: More formatting and English tweaks,
5646 many suggested by Ralf Wildenhues.
5647 Reword to avoid "@code{...}'s" and the like, since it's ugly
5648 with Emacs info mode. discontents -> woes.
5649 Put a few "will"s back. time stamp -> timestamp.
5650 side-effect -> side effect.
5652 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5654 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5655 Warn about $@ not persisting. Problem reported by Julien Danjou in
5656 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5657 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5658 Mention other special chars, too.
5660 2006-06-14 Eric Blake <ebb9@byu.net>
5662 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5664 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5666 * doc/autoconf.texi: Some systematic minor improvements, as
5667 follows. Use "makefile" when talking about makefiles
5668 generally (which might be named "makefile" or "Makefile" or even
5669 "foo.mk"), "Makefile" when talking about a specific makefile
5670 called "Makefile". This unclutters the text from weird quotes
5671 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5672 values" rather than "@var{foo}s" and similar constructs containing
5673 "}s". Use "Make rules" rather than "Makefile rules". Minor
5674 English-language improvements. Change the prefix "sub-" to "sub"
5675 and "re-" to "re".
5676 Put blank lines around examples more consistently.
5677 Avoid "rather" and "very" as intensifiers.
5678 Avoid "will" as an auxiliary.
5679 (Limitations of Make): Split this node into....
5680 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5681 (Leading _ in Macro Names, Backslash-Newline-Newline):
5682 (Backslash-Newline Comments, Long Lines in Makefiles):
5683 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5684 (obj/ and Make, make -k Status, VPATH and Make):
5685 (VPATH and Double-colon, $< in Explicit Rules):
5686 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5687 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5688 New nodes, resulting from splitup of Limitations of Make.
5689 All cross-references changed. Raise the top node from
5690 a section to a chapter, and all subnodes accordingly.
5691 Redo the introductory wording to match the new organization.
5692 (Installation Directory Variables): Use an example that is
5693 closer to what Autoconf actually does. Mention that VPATH's
5694 value should not contain metacharacters or white space.
5695 (Fortran Compiler): Fix a VPATH bug in an example.
5696 (Leading _ in Macro Names): Mention that this problem is no longer
5697 of practical concern.
5698 (VPATH and Make): Reword the advice to make it clearer
5699 that Autoconf and Automake support VPATH in non-GNU make, but
5700 many packages have bugs in this area.
5701 ($< in Explicit Rules): Refer to Build Directories rather
5702 than using a (non-VPATH-safe) example.
5703 (Automatic Rule Rewriting): Mention the sort of disaster that
5704 can ensue with Solaris-style rule rewriting with VPATH.
5706 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5708 * doc/install.texi (Compilers and Options): Weaken the
5709 suggestion to use GNU make for VPATH builds.
5711 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5712 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5714 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5715 in regular expression.
5717 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5719 * doc/autoconf.texi (Installation Directory Variables):
5720 Drop extra @samp from `@table @samp' item.
5721 (Limitations of Usual Tools): Comment fix.
5722 Do not nest @samp just to point to other table items.
5723 (Writing testsuite.at) <AT_CHECK>: The second argument to
5724 `@dvar' is already @samp'ed.
5725 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5726 do not use @var in the second argument.
5728 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5730 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5731 $as_shell.exe too. Problem reported by Andreas Buening in
5732 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5734 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5736 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5737 `unused variable' compiler warning, for `-Wall -Werror'.
5738 Reported by Jaap Haitsma in
5739 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5741 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5743 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5744 case the compiler dumps core. Problem reported for
5745 OpenServer 5.0.7 by Tim Rice in
5746 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5747 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5748 Likewise.
5750 2006-06-06 Tim Rice <tim@multitalents.net>.
5752 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5753 "ERROR" only shows up in "make check" output if there is an
5754 error.
5756 2006-06-06 Eric Blake <ebb9@byu.net>
5758 * tests/tools.at (automatically allowed tokens): Fix typo.
5760 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5762 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5764 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5765 typically overflows on x86 CPUs, even though the C standard
5766 requires otherwise.
5768 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5770 * configure.ac (AC_INIT): Bump to 2.59e.
5771 * NEWS: Update.
5773 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5775 Version 2.59d.
5777 * config/texinfo.tex: Sync from upstream.
5779 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5780 seen, invoke libtoolize with `--ltdl' argument.
5781 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5782 * NEWS: Update.
5783 Suggested by Eric Blake.
5785 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5787 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5788 reported by Ralf Wildenhues.
5789 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5791 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5793 * THANKS: Update.
5795 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5797 * doc/autoconf.texi: Modernize some of the references to Solaris.
5799 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5801 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5802 message issued by AC_REQUIRE.
5803 * tests/m4sugar.at: Check m4_require's error message.
5804 * tests/base.at: Check AC_REQUIRE's error message.
5805 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5806 to...
5807 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5808 AT_CHECK_M4.
5809 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5810 `expout' as the last parameter.
5811 * tests/tools.at: Adapt to the above change.
5813 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5815 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5816 information about race-free implementations of mkdir.
5818 2006-06-04 Eric Blake <ebb9@byu.net>
5820 * bin/autoreconf.in (help): Document M4 environment variable.
5821 * bin/autoconf.as (Usage): Likewise.
5822 * bin/autom4te.in (help): Likewise.
5823 * doc/autoconf.texi (autom4te Invocation): Likewise.
5825 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5827 * NEWS: GNU make now recommended for VPATH builds.
5828 Mention that some macros are now documented to be obsolescent.
5829 * doc/autoconf.texi:
5830 Prefer "current" to "modern" to describe
5831 currently-used (albeit perhaps old-fashioned) hosts.
5832 Mention which ancient features no longer need to be worried about.
5833 setgid -> set-group-ID
5834 setuid -> set-user-ID (these are the Posix terms)
5835 Fix some misuses of "only".
5836 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5837 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5838 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5839 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5840 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5841 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5842 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5843 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5844 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5845 Mention that these macros are obsolescent.
5846 (Installation Directory Variables): shall -> should
5847 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5848 Mention that it's now safe to use 3 and 4.
5849 (Limitations of Usual Tools): cp -r is now specified by Posix.
5850 Omit longwinded and obsolescent discussion of cp -f.
5851 Modernize discussion of expr, ls.
5852 (Limitations of Make): Modernize discussion of VPATH builds.
5853 Mention $? as a workaround in some cases.
5854 * doc/install.texi (Basic Installation):
5855 Mention "./configure; make; make install" first. Be more
5856 specific about why this file is generic. Remove unnecessary
5857 parens. Remove misleading "only". Remove obsolete advice
5858 about csh. Don't say "configure" takes awhile; say it
5859 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5860 and CC=c99 rather than CC=c89, as these are blessed by current
5861 Posix. Recommend GNU make if doing a VPATH build.
5863 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5865 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5866 examples involving shell prompts.
5868 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5869 and Paul Eggert <eggert@cs.ucla.edu>
5871 * doc/autoconf.texi (Here-Documents): Add details about the
5872 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5873 use "here-documents" instead of "here documents".
5875 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5877 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5879 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5881 * doc/autoconf.texi (File System Conventions): Warn about ":"
5882 anywhere in directory names.
5884 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5886 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5887 about quoting the case statement, just in case.
5888 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5889 was fixed in ksh93g; reported by Ralf Wildenhues.
5891 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5893 * doc/autoconf.texi (System Services): Do not document
5894 overriding EXEEXT via ac_cv_exeext=ext.
5895 (Particular Programs) <AC_PROG_MKDIR_P>:
5896 Document that ${MKDIR_P} understands --.
5897 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5898 comment.
5900 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5902 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5903 argument with leading hyphen. Problem reported by Paul Eggert.
5905 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5907 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5908 about quoting ac_try: quote all of it, if any of it seems suspicious.
5909 This means we don't have to worry about ${ or sed any more.
5910 Also, double-quote the case statement, to work around misuses via
5911 underquoting as reported by Ralf Wildenhues in
5912 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5913 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5914 undocumented and dangerous macro.
5915 Problem reported by Ralf Wildenhues in
5916 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5918 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5920 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5921 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5922 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5924 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5926 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5927 since evidently some packages rely on the old, broken behavior.
5928 Problem reported by Ralf Wildenhues in
5929 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5930 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5931 pre-2006-05-26 definitions, but leave in the comments that
5932 these macros are dangerous and should not be used.
5933 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5934 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5935 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5936 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5937 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5939 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5941 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5942 the use of 'tr', since this is our only use of 'tr'.
5944 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5945 and Paul Eggert <eggert@cs.ucla.edu>
5947 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5948 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5950 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5952 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5953 the output file in the `${datarootdir}' test.
5955 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5956 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5958 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5959 mention of `datarootdir' in the input file(s), but literal
5960 `${datarootdir}' in the output file, and we haven't warned yet,
5961 then warn as well: the user may have (erroneously) used
5962 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5963 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5964 * tests/torture.at (datarootdir workaround): Extend this test.
5965 * NEWS: Update.
5967 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5968 and Paul Eggert <eggert@cs.ucla.edu>
5970 * doc/autoconf.texi (autoheader Invocation): The first argument to
5971 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5972 alternatives and clear up the language a bit.
5974 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5976 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5977 ac_config_guess, ac_config_sub, ac_configure.
5978 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5979 Fix typo that prevented an unnecessary space from being removed.
5980 Problems reported by Ralf Wildenhues in:
5981 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5983 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5985 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5986 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5987 Don't use the term "thread-safe" to talk about mkdir race
5988 conditions, since the problem is more a process than a thread
5989 issue. Problem reported by Stepan Kasal in:
5990 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5991 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5992 the test for 'install' more closely. Look at MKDIR_P first.
5993 Look in the PATH, and at /opt/sfw/bin.
5994 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5995 Don't bother to try mkdir -p, since we already check mkdir --version;
5996 just look at the version number. (There's no easy way to check
5997 for race-free implementations.)
5998 * tests/tools.at (autoconf: subdirectories): Adjust to above
5999 changes, since MKDIR_P now might end in "/mkdir -p".
6001 * doc/autoconf.texi (autoheader Invocation): Mention that the
6002 first arg of AC_DEFINE_UNQUOTED must be a literal.
6003 Problem reported by Ben Pfaff in
6004 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
6006 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
6007 * doc/autoconf.texi (Special Chars in Variables): New section.
6008 (Preset Output Variables): Warn about special chars in CPPFLAGS.
6009 (Installation Directory Variables): Quote $(datadir) better.
6010 (Limitations of Builtins): Describe some of eval's trickiness.
6012 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
6013 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
6014 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
6015 in front of every arg, not just trailing args. Quote apostrophes.
6016 (_AC_EVAL_ECHO): New macro.
6017 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
6018 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
6019 removed.
6020 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
6021 exposed by quoting of eval argument. Put the command on line line
6022 so it logs better.
6023 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
6024 (_AC_PATH_X, AC_PATH_X): Quote more safely.
6025 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
6026 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
6027 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
6028 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
6029 Use eval more safely.
6030 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
6031 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
6032 to be replaced.
6033 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
6034 lines, exposed by quoting of eval argument.
6036 2006-05-26 Stepan Kasal <kasal@ucw.cz>
6037 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6039 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
6040 initialization of `ac_cv_exeext', do not override it if it was
6041 already set, unless it was set to `no', for compatibility with
6042 Autoconf-2.13, and comment this.
6043 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
6044 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
6045 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
6046 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
6047 Document that this test may be overridden by setting
6048 `ac_cv_exeext'.
6050 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6052 Revert these two patches:
6054 2006-04-06 Eric Blake <ebb9@byu.net>
6055 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6056 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6057 2006-04-01.
6059 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6060 Clean up _AC_COMPILER_EXEEXT* macros.
6061 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6062 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6063 ac_file to the name of the default output file and call
6064 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6065 initial `rm' of the candidate files...
6066 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6067 the same list in subsequent `rm' calls, and for the temporary
6068 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6069 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6070 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6071 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6072 no longer needed) by libtool. Make it a cache check.
6073 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6074 copied here by mistake.
6075 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6076 _AC_COMPILER_EXEEXT.
6077 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6078 _AC_COMPILER_OBJEXT directly.
6079 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6081 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6083 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6084 Fix description of how the buggy `sed' works.
6086 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6088 Sync from Automake:
6090 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6091 ENOLCK. Only mention `make -j' when applicable. Only raise
6092 fatal errors when `make -j' is involved. Improve error message.
6094 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6096 * doc/autoconf.texi (Here-Documents): We now know more about
6097 the variable expansion in here documents bug.
6098 Thanks to Tim Rice and Stepan Kasal.
6100 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6101 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6103 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6105 * tests/autotest.at (Multiline command from M4 expansion):
6106 No failure to be expected if the shell quotes newlines in
6107 commands in the `set -x' output. Report by Tim Rice.
6108 * THANKS: Update.
6110 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6112 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6113 expansion in the here-documents used by config.status, as that
6114 runs afoul of the Korn shell version M-12/28/93d bug described in
6115 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6116 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6117 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6119 2006-05-23 Jim Meyering <jim@meyering.net>
6121 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6122 Fix typo introduced with 2006-04-02 change. It reversed the sense
6123 of the test.
6125 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6127 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6128 ac_dB slightly, to save bytes in the script.
6129 Max out at 50 lines, rather than 96; this is more likely
6130 (though not guaranteed) to avoid obscure 'sed' failures.
6132 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6134 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6135 `tr -d -' as bad option argument. Work around this by deleting
6136 an unrelated character.
6137 Report by Tim Rice <tim@multitalents.net>.
6139 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6140 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6141 Stepan Kasal <kasal@ucw.cz>
6143 * doc/autoconf.texi (Particular Programs): Do not promise that
6144 we always prefer the GNU version of the program, and that we
6145 search according to PATH; both rules can have exceptions.
6146 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6147 AC_PROG_SED. Move descriptions of limitations
6148 to the Limitations of Usual Tools section.
6149 (Limitations of Usual Tools) <sed>: Mention script length
6150 limitations with Solaris /usr/ucb/sed.
6151 <grep>: Fix wording for empty alternative. Mention that -c and
6152 -l should not be combined, and that -E and -F should not be
6153 combined.
6155 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6156 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6158 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6159 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6161 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6163 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6164 AC_DEFINE is now passed to m4_pattern_allow.
6165 * NEWS: Mention that; likewise for AC_SUBST.
6166 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6167 the parameter to m4_pattern_allow.
6168 * tests/tools.at: Add a check for that.
6170 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6172 * lib/autoconf/status.m4: Fix typos.
6174 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6176 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6177 only the files that this macro generates.
6179 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6181 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6182 the HP-UX sed limitation of 99 commands, labels do not count.
6183 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6184 in the comment.
6185 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6187 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6189 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6190 Import the following fix from coreutils:
6192 2006-01-13 Jim Meyering <jim@meyering.net>
6194 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6195 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6196 not double-quote uses of that variable, to accommodate the rare
6197 case in which getmntent is available in none of the libraries
6198 checked. This happens at least on FreeBSD 5.0.
6200 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6202 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6203 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6204 some other programs unwisely rely on these undocumented vars.
6205 But put in warning comments about them.
6206 Problem reported by Ralf Wildenhues in
6207 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6208 * NEWS: Document that these variables are intended to go away.
6210 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6212 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6213 and set the language to C++ (analogous to the equivalent Fortran
6214 tests).
6216 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6217 * doc/autoconf.texi (C++ Compiler): Document it.
6218 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6219 * NEWS: Update.
6221 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6223 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6224 that caused config.status to generate 100-command sed scripts; the
6225 portable limit is 99.
6227 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6229 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6230 variable `ac_d' instead of `d' to avoid infringing namespace.
6231 Report by Ralf Menzel.
6233 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6235 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6236 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6237 * tests/tools.at (autoconf: subdirectories): New test, taken from
6238 the corresponding problem report by Ralf Wildenhues in:
6239 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6241 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6242 Quote some uses of shell variables if they might suffer unexpected
6243 globbing. This doesn't fix all instances of quoting problems that
6244 I found, just the easy ones that look safe.
6245 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6246 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6247 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6248 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6249 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6250 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6251 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6252 Likewise.
6253 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6254 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6256 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6258 * bin/autoreconf.in ($help): Reword according to the manual.
6259 Suggested by Olly Betts.
6261 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6262 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6264 * bin/autoreconf.in: Pass the directory argument to
6265 `require_configure_ac'. Fix comment.
6266 * tests/torture.at (Configuring subdirectories): Expose this.
6267 Reported by Olly Betts.
6269 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6271 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6272 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6273 Automake as follows:
6275 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6276 `$configure_in' instead of `configure.in', to preserve
6277 directory component.
6279 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6281 * config/config.guess, config/config.sub, config/texinfo.tex,
6282 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6284 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6286 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6287 test for C99 conformance; (bool) 0.5 is an integer constant
6288 expression, but (bool) -0.5 is not. Problem reported by Fedor
6289 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6291 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6293 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6294 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6295 Warn about obsolete install-sh files. Remove stray sentence
6296 fragment and fix cross reference.
6297 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6298 install -d; this undoes the 2006-05-10 change.
6299 (MKDIR_P): Mark with AN_MAKEVAR.
6300 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6301 that we don't require $INSTALL to be thread-safe. Move comments
6302 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6303 of AC_PROG_INSTALL. Output a message saying that we're checking
6304 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6305 MKDIR_P instead of AC_SUBST.
6306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6307 Special magic for MKDIR_P, too.
6308 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6309 a dnl.
6310 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6312 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6314 Sync from Automake, as follows:
6316 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6317 * config/install-sh: Initialize IFS, so field splitting isn't
6318 turned off later.
6319 * config/mkinstalldirs: Likewise.
6320 * config/missing: Remove superfluous quotes. Replace all uses of
6321 `[' by `test', for consistency, and for..
6322 * config/missing (sed_minuso, sed_output): New variables.
6323 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6324 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6325 Fixes `missing' to detect `--output' for help2man. Fixes
6326 PR automake/483. Report by Dennis J. Linse.
6327 (autom4te): Document in `missing --help'.
6329 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6331 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6332 * config/install-sh: Don't use 'path' to talk about file names,
6333 as per GNU coding standards. Close a race condition reported by Ralf
6334 Wildenhues and Stepan Kasal. There is still a race condition
6335 on hosts that predate Posix 1003.1-1992, but we can't help this.
6336 Don't mishandle weird characters like space on pre-Posix hosts.
6337 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6338 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6339 AC_PROG_MKDIR_P from AS_MKDIR_P.
6340 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6341 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6342 earlier editions are not (including Automake 1.8.3).
6343 Do not suggest mkinstalldirs for thread-safety.
6344 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6345 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6346 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6347 presence of special characters and race conditions.
6348 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6349 in Autoconf's name space.
6351 2006-05-10 Bruno Haible <bruno@clisp.org>
6352 and Paul Eggert <eggert@cs.ucla.edu>
6354 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6355 from Automake with minor changes.
6356 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6358 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6360 * config/install-sh: Update to Automake CVS version, as follows:
6361 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6362 * lib/install-sh: Simplify the expr implementation of dirname.
6363 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6364 * lib/install-sh: Handle --, and diagnose unknown options.
6366 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6368 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6369 `./autom4te' to create `./testsuite', since the `all' target
6370 will ensure its presence, but `installcheck' should not create
6371 the uninstalled wrappers.
6373 * tests/torture.at (Unusual Automake input files): Skip if we
6374 detect automake < 1.8.
6376 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6378 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6379 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6380 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6381 * NEWS: Update.
6383 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6385 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6386 munge (multiple) white space and other oddities.
6387 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6388 single quotes in variable assignment.
6389 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6390 and similar failures by adding multiple spaces, tabs, and other
6391 special characters.
6392 Report and different test suggested by Francesco Romani
6393 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6395 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6396 single quotes, we only need to search for single quotes; this
6397 both simplifies the search pattern, and makes us less
6398 susceptible to `echo' variations for arguments not containing
6399 single quotes.
6400 (_AC_ARG_VAR_VALIDATE): Likewise.
6402 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6404 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6405 `$*' and IFS concatenation issue with traditional shells and
6406 bash-2.04. Report by Seanster@Seanster.com.
6408 2006-05-03 Bruno Haible <bruno@clisp.org>
6410 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6411 precisely which Mac OS X versions have the od problem.
6413 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6415 * doc/autoconf.texi: Use @option systematically.
6417 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6418 and Bruno Haible <bruno@clisp.org>
6420 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6421 about 'od'.
6422 (Integer Overflow): Mention the special case of integer division
6423 overflow.
6425 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6427 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6428 traditional shells like the Solaris one that do not use the
6429 first IFS character for assembling `$*'.
6430 Prompted by a related report from autoconf_bug@nro.ca.
6432 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6433 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6435 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6436 Mention more problems with the -e option.
6438 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6440 * NEWS: Typo.
6441 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6443 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6444 in URLs to improve DVI formatted output (requires texinfo 4.6).
6445 (System Services, Systemology, Shellology): Likewise.
6446 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6447 output.
6449 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6450 continuous text.
6451 (Runtime): Fix macro argument names to match description:
6452 `action-if-found' -> `action-if-true' and similarly.
6453 (Obsolete Macros): Likewise.
6454 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6455 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6456 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6458 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6460 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6462 * ChangeLog: Typo.
6463 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6464 DVI output.
6466 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6475 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
6476 (Integer Overflow, Null Pointers, Buffer Overruns):
6477 (Floating Point Portability, Exiting Portably): New sections.
6478 (Writing Test Programs): Fix some langauge. Recommend exiting
6479 with status 1, not merely nonzero. Clarify exit declaration.
6480 (Run Time): Move C exit status stuff to new Exiting Portably section.
6481 (Systemology): Mention Posix and levenez. Update v7 reference.
6482 (Portable Shell): Mention the Posix shell.
6484 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6486 * bin/autoconf.as (me): Replace by as_me.
6488 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6490 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6491 since as_me isn't set yet.
6493 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6495 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6496 a few minor bugs in this area.
6498 * doc/autoconf.texi (Programming in M4sh): Comment out the
6499 documentation of AS_BASENAME, for now.
6500 (Shell Substitutions): Do not use AS_DIRNAME in an example.

6505 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6506 AS_DETECT_REQUIRED. All uses changed.
6507 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6508 All uses changed.
6509 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6510 (AS_BASENAME): Use "basename --" to protect against leading "-".
6511 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
6512 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6513 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6514 (_AS_DIRNAME_PREPARE): Likewise.
6515 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6516 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6517 (AS_DIRNAME): Use "dirname --".
6519 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6521 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6522 of "run time" and "run-time" changed to "runtime", for consistency.
6523 * lib/autoconf/fortran.m4: Likewise (in comment).
6524 * lib/autoconf/functions.m4: Likewise.
6525 * lib/autoconf/general.m4: Likewise.
6526 * lib/autoconf/headers.m4: Likewise.
6528 * doc/autoconf.texi (Run Time): Document the exit status situation
6529 with more accuracy and detail.
6531 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6533 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6534 Archive is not officially `GNU' any more. Update URL.
6535 (Defining Directories): Likewise
6536 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6538 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6540 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6541 newline from the `trap' code to finish `config.log'; the NetBSD
6542 /bin/sh resets the exit status after an empty command, as
6543 documented in doc/autoconf.texi.
6544 Reported by Dalibor Topic <robilad@kaffe.org>.
6546 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6548 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6549 Suggested by Bruno Haible.
6551 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6553 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6554 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6555 Instead, just list the shells that we know work.
6556 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6557 changed. Be more cautious about the _cv_ variable.
6558 * tests/tools.at (Syntax of the shell scripts): Check the
6559 _cv_ variable once, at first, to avoid an internal autoconf error
6560 when sh -n does not work.
6562 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6564 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6566 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6568 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6569 use ">&-" since we're only 99.999% sure that this is portable,
6570 and since the MinGW bug is fixed in a different way.
6571 * lib/autotest/general.m4 (AT_INIT): Likewise.
6573 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6575 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6576 before opening config.log, to avoid hitting a bug on MinGW.
6578 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6580 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6581 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6582 This works around a MinGW bug reported by Eric Paire.
6583 Make sure that all writes to the log file append to it,
6584 rather than possibly losing data.
6585 * lib/autotest/general.m4 (AT_INIT): Likewise.
6587 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6589 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6590 description.
6592 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6594 * NEWS: Update.
6596 * configure.ac (AC_INIT): Bump to 2.59d.
6598 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6600 Version 2.59c.
6602 * Makefile.maint (news-date-check): Do not require a leading `*'
6603 before the release date in NEWS.
6605 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6606 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6608 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6609 the instantiated file do not contain the string 'datarootdir'
6610 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6611 @mandir@, replace the reference '${datarootdir}' by the value.
6612 * tests/torture.at (datarootdir workaround): New test.
6613 * NEWS: Advertise this temporary fixup.
6614 Based on a patch by Bruno Haible, reported and analyzed by
6615 Paul Eggert and Noah Misch.
6617 2006-04-12 Eric Blake <ebb9@byu.net>
6619 * tests/autotest.at (Debugging a failed test): Fix comment.
6621 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6623 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6624 all the changes since 2006-04-07.
6626 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6628 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6629 succeeded, but `ln -s file dir' failed, take care to remove the
6630 leftover target before the next test, to prevent its spurious
6631 failure; also make sure `ln file dir' works before selecting it.
6632 Thanks to Keith Marshall for pointing this out.
6633 * THANKS: Update.
6635 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6636 assignments in `at_debug_args', so that we put them correctly
6637 in the `run' script.
6638 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6639 Reported by Eric Blake.
6641 2006-04-11 Eric Blake <ebb9@byu.net>
6643 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6644 top-level tests after micro-suite has been run. Used in...
6645 (Debugging a successful test, Debugging script and environment),
6646 (Debugging a failed test): ...these new tests. The first of these
6647 is fixed by...
6648 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6649 macro, split out from...
6650 (AT_INIT): ...here, so that using -d also generates a run script.
6651 Document that -d inhibits top-level logging.
6652 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6653 inhibits top-level logging; debug scripts are created.
6655 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6656 check.
6657 * tests/autotest.at (Empty test, Empty check): New test to check it.
6659 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6660 from gcc.
6662 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6664 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6665 the files if a problem appears. Make the empty *.at files
6666 read-only, too. Proposed by Ralf Wildenhues.
6668 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6670 * config/Makefile.am: Add comment to force updated Makefile.in.
6672 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6673 space only patch to this file, this patch causes the Makefile.in
6674 files that include freeze.mk to be updated, and thus have a
6675 newer time stamp again, which in turn makes a pristine CVS
6676 checkout have correct time stamps.
6678 * Makefile.maint (cvs-sv): New macro, to be used..
6679 (config.guess-url_prefix, config.sub-url_prefix)
6680 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6681 point to CVS text checkout of Gnulib files.
6682 (copyright-check): Bump current year.
6683 (announcement): Do not hard-wire `./announce-gen'.
6684 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6685 correctly.
6686 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6687 `chmod +x'.
6688 (wget_files): Update config.guess, config.sub, texinfo.tex by
6689 `wget-update', now that their URLs work again.
6691 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6693 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6694 Problem noted by Paul D. Smith.
6696 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6698 * doc/autoconf.texi: Remove unused words from word list.
6699 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6700 .x-sc_trailing_space: New files.
6702 * doc/standards.texi: Sync from gnulib.
6704 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6705 `LIBOBJDIR' as experimental.
6707 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6708 with a target directory; it's internally implemented as `cp'
6709 anyway, but since Autoconf advertises the possibility to use
6710 a target directory when LN_S is `ln -s', we need to find out.
6711 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6712 analyzed by Keith Marshall <keith.marshall@total.com>.
6714 * THANKS: Update.
6716 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6718 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6719 confdefs.h as-is. In general, if it has backslash-newline or the
6720 like, then it doesn't work either to sort or to remove empty
6721 lines.
6723 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6725 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6727 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6729 * lib/autom4te.in (Automake-preselections): Preselect
6730 _AM_SUBST_NOTMAKE.
6732 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6734 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6735 apostrophe within a single-quoted string, as this is the usual
6736 tradition and is easier to read than '"'"'. Don't rely on the
6737 shell treating "$/" like '$/'. Use a more-consistent indenting
6738 style for the trap.
6740 2006-04-09 Eric Blake <ebb9@byu.net>
6742 * tests/autotest.at (Backquote command substitution),
6743 (Multiline backquote command substitution): Remove mistaken
6744 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6745 applied...
6746 (Parenthetical command substitution, Multiline parenthetical
6747 command substitution): here.
6749 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6751 Import macros from gnulib (often changing their name).

6765 (Pointers): Add Gnulib URL.
6766 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6767 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6768 Gnulib section.
6769 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6770 suggest a #define rather than a typedef for _Bool, and mention
6771 Gnulib rather than trying to substitute stdbool code.
6772 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6773 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6774 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

6777 headers too.
6778 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6779 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6780 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6781 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6782 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6783 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6784 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6785 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6786 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6787 (Coding Style). Don't mention m4_expand_once.
6788 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6789 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6790 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6791 (AC_CHECK_FUNCS): Use it.
6792 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
6793 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".

6795 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
6796 (AC_HEADER_ASSERT): New macro.
6797 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6798 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6799 Catch a bug in an HP-UX C compiler.
6800 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6801 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6802 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

6805 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6806 New macros.
6808 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6809 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6811 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6813 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6814 of the warning introduced by the 2001-08-28 change.
6816 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6817 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6819 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6820 variables shall be overriden by the cache.
6821 * tests/torture.at (AC_ARG_VAR): Test also with a first value
6822 that contains braces.
6824 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6826 Revert the patch from 2006-04-01 and only improve
6827 _AS_DETECT_BETTER_SHELL:
6829 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6830 skip nonexistent directories.
6831 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6832 only shell candidates which exist.
6833 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6834 * lib/autotest/general.m4 (AT_INIT): No need to give three
6835 parameters to _AS_PATH_WALK.
6837 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6838 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6840 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6841 distinguish m4sugar macros.
6842 * tests/tools.at (autoupdating with aclocal and m4_include):
6843 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6844 test case by Noah Misch <noah@cs.caltech.edu>.
6846 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6848 Revert my change from 2006-03-17, in other words:
6849 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6850 and DUALCASE=1.
6851 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6852 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6853 it is set.
6855 2006-04-07 Eric Blake <ebb9@byu.net>
6857 * doc/autoconf.texi (Programming in M4sh): Document that
6858 AS_MKDIR_P exits the script on failure.
6859 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6861 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6863 * config/elisp-comp, config/install-sh, config/mdate-sh,
6864 config/missing, config/mkinstalldirs: Sync from Automake.
6866 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6867 from Automake.
6869 * doc/make-stds.texi: Sync from gnulib.
6871 2006-04-06 Eric Blake <ebb9@byu.net>
6873 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6874 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6875 2006-04-01.
6877 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6878 Eric Blake <ebb9@byu.net>,
6879 Paul Eggert <eggert@cs.ucla.edu>,
6880 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6882 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6883 whether `set' quotes correctly: redirect stderr of the tested
6884 `set', and use a subshell, for Ultrix; use `sed' instead of
6885 `grep' for zsh `set' which may write binary output; match only
6886 at the beginning of a line, to avoid false positives.
6887 In order to avoid false positives by unrelated variables with
6888 multiline content, put the dump algorithm in a subshell and
6889 unset all variables containing newlines (except some which are
6890 special to the shell). Warn about cache variables that are
6891 unset.
6893 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6895 * config/config.guess, config/config.sub, config/texinfo.tex:
6896 Sync from upstream.
6898 * tests/mktests.sh: Reword comments.
6900 * tests/mktests.sh: Only skip internal macros starting with
6901 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6902 Update exclusion lists for the test suite to this end:
6903 (AC_ARG_VAR): Do test this now.
6904 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6905 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6906 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6907 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6909 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6910 shell issue with double-quoted command substitutions of native
6911 commands.
6912 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6913 Marshall.
6915 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
6916 no file matches the glob, discard the warning, set `nullglob'.
6917 (syntax-check): Likewise.
6918 (sc_cast_of_x_alloc_return_value): Likewise.
6919 (sc_cast_of_alloca_return_value, sc_error_exit_success)
6920 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
6921 (m4-check): Likewise.
6922 (sc_system_h_headers): Do not print rule on execution.
6923 (sc_tight_scope): Do not fail for non-existing `src' directory.
6924 (sc_changelog): Skip the Copyright footer.
6925 * lib/autoconf/lang.m4: Remove trailing space.
6927 * lib/autoconf/status.m4: More replacements to
6928 <tab><space> where this makes sense.
6930 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6932 * tests/Makefile.am (maintainer-check-posix):
6933 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6935 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6936 ac_config_<foo>s again, sometimes normalized, sometimes not.
6937 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6938 (AC_CONFIG_COMMANDS): Do not do so here.
6939 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6940 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6941 2005-07-25 rewrite. Noticed by Noah Misch.
6943 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

6951 for --help from Cygnus `configure.'
6953 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

7009 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
7010 (exclude_list): Exclude empty macros.

7094 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to

7096 ac_file to the name of the default output file and call
7097 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7098 initial `rm' of the candidate files...
7099 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7100 the same list in subsequent `rm' calls, and for the temporary

7102 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
7103 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7104 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7105 no longer needed) by libtool. Make it a cache check.
7106 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
7107 copied here by mistake.
7108 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
7109 _AC_COMPILER_EXEEXT.
7110 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

7146 subordinate tools.
7147 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
7148 * doc/autoconf.texi (autoreconf Invocation): Document it.
7150 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

7182 2006-04-01 Stepan Kasal <kasal@ucw.cz>
7184 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
7185 switch all of them on and of when necessary. Fixes the bug when
7186 m4sugar macros (e.g., m4_define) were expanded after the first
7187 automatic update (e.g., after AC_PREREQ or AC_INIT).
7189 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

7237 checked for existence, so we don't barf over a nonexisting
7238 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
7240 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7305 (AC_CHECK_SIZEOF, AC_CHECK_SIZEOF struct): Use it.

7364 keywords, keywords taken from AT_SETUP arguments, and numeric

7384 trying to execute the command `no'.
7386 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not

7862 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
7863 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
7864 code so that the most common case requires less forks.
7866 2005-10-20 Stepan Kasal <kasal@ucw.cz>
7868 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
7869 not portable; thanks to Paul Eggert and Alexandre.
7871 * NEWS: Fix an old typo.
7873 2005-10-20 Jim Meyering <jim@meyering.net>
7875 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
7876 the latter'', in two places.
7878 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7880 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7881 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7882 the inner workings of AC_LANG_FUNC_LINK_TRY.
7883 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7884 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7885 by the function rather than ignoring it.
7886 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7887 comparing its address. Intel's interprocedural optimization was
7888 outsmarting the old heuristic. Problem reported by
7889 Mikulas Patocka.
7891 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7893 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7895 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7897 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

7900 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7902 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7903 before removing it (chmod -R u+rwx); there are three instances of this.
7905 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7906 Stepan Kasal <kasal@ucw.cz>
7908 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7909 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7910 make its content writable before removing it. Remove an errorneous
7911 comment from the end, where the logs of the failed tests are copied
7912 to the main log file.
7914 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7916 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7917 in case the computer is too quick. Double quote the configure.ac
7918 snippets.
7920 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7921 problems if the testsuite were running too fast.
7923 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7925 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7926 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7927 (which belong to Xt, not X itself). See Debian bug 327655.
7928 * NEWS: Mention this.
7930 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7932 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7934 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7936 * config/move-if-change: Don't output "$2 is unchanged";
7937 suggested by Ben Elliston. Handle weird characters correctly.
7939 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7941 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7942 calls, so that the final expansion of this macro is shorter.
7943 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7944 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7945 the cleanup there. Use AS_VAR_* macros, to be more general.
7946 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7948 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7950 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7952 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7954 * doc/autoconf.texi (Configuration Headers): Add an index entry
7955 for AH_HEADER.
7957 2005-08-26 Pavel Roskin <proski@gnu.org>
7959 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7960 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7961 running xmkmf.
7963 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7965 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7966 The previous patch didn't work, so try a better one.
7968 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7970 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7971 in the example. Reported by Bruno Haible.
7972 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7973 "if $undefined_var;" succeeds with my shell.
7975 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7976 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7977 but change the m4_divert_text to m4_divert_once.
7979 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7981 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7982 Work around bug in Solaris /usr/xpg4/bin/awk.
7983 The bug is present in at least Solaris 8 through 10.
7985 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7987 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7988 some evil values and relying on the fact that $* concatenates the
7989 parameters by the first character from IFS.
7991 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7992 Stepan Kasal <kasal@ucw.cz>
7994 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7995 first header appears, define AH_HEADER.
7996 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7997 Update limitations about when to call AC_CONFIG_HEADERS.
7998 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7999 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
8000 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
8001 ``Configuration Actions''; fix their index entries.
8003 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
8004 options correctly. Process N-M as M-N if M is smaller than N.
8005 Process ranges correctly so that N-N will run only N.
8006 Sort and uniquify the tests that will be run. If there is more
8007 than one test, reinsert the banners for the tests.
8008 * tests/autotest.at (Keywords): Unmark XFAIL.
8010 2005-08-23 Stepan Kasal <kasal@ucw.cz>
8012 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
8013 before passing the macro name to AH_TEMPLATE.
8015 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
8016 now opens log after option processing; in particular, --version
8017 and --help do not touch config.log.
8019 * Makefile.maint: Revert the change from 2005-08-12.
8021 2005-08-22 Stepan Kasal <kasal@ucw.cz>
8023 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
8024 common code to...
8025 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
8027 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8029 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
8030 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
8031 Language cleanup.
8033 * doc/autoconf.texi (Defining Symbols, Changed Results):
8034 Prepend to LIBS, not append, in examples.
8036 2005-08-16 Stepan Kasal <kasal@ucw.cz>
8038 When building in place, set srcdir="."; suggested by Tim Van Holder.
8040 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
8041 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
8042 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
8043 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
8044 does not mean "no --srcdir option".
8046 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8048 * tests/autoscan.at (autoscan): New file.
8049 * tests/suite.at: Use it.
8050 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
8051 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
8053 * tests/autotest.at (Keywords): Test keywords combinations.
8055 2005-08-12 Stepan Kasal <kasal@ucw.cz>
8057 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8058 add "2>&1"; gzip 1.2.4 prints help on stderr.
8060 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8062 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8063 was pushdef'ed twice while popped only once. Push it only once.
8064 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8066 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8068 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

8073 * Makefile.maint: Update from Bison.
8075 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8076 "<tab>" in comment, so that the point is understandable.
8078 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8080 Rewrite substantial part of lib/autoconf/status.m4.
8081 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8082 and CONFIG_COMMANDS are not processed in four separate loops.
8083 Instead, there is one main loop. This alows that the common code
8084 is expanded only once, thus config.status (and configure) is smaller.
8086 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8087 the AC_LIST_FILES and cousins macros are no longer used.
8089 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8090 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8091 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8092 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8093 contain the initialization, nor the for loop, nor the associated
8094 commands; all these go to ...
8095 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8096 _AC_OUTPUT_CONFIG_STATUS.
8097 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8098 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8099 (_AC_OUTPUT_FILE): The creation of the sed script ...
8100 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8101 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8102 _AC_OUTPUT_MAIN_LOOP.
8103 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8104 _AC_CONFIG_COMMANDS): Use ...
8105 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8106 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8107 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8108 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8109 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8110 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8111 ... new macros.
8112 (_AC_CONFIG_UNIQUE): Update.
8113 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8114 Replaced by this ...
8115 (_AC_LIST_TAGS): ... new common macro.
8116 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8117 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8118 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8119 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8120 this didn't belong to the `config commands' section.
8121 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8122 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8123 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8124 to the `config commands' section either.
8125 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8126 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8128 ... and many changes to the comments nearby.
8130 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8131 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8132 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8133 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8134 (#define header templates): The comment at the top of the generated
8135 header now includes the name(s) of the source file(s).
8137 Several unrelated small changes:
8139 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8140 parameter to AC_DIAGNOSE.
8141 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8142 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8143 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8144 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8145 with AU::AC_OUTPUT.
8146 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8147 in AC_OUTPUT doesn't double-quote it either.
8148 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8149 parameters.
8151 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8153 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8154 versions of Portland Group compiler produce single- and double-quoted
8155 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8156 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8158 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8160 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8161 This is a corrected version of yesterday's patch.
8163 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8165 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8166 path, too; insert a "===" to emphasize the line.
8168 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8169 ac_cv_build_alias to ac_build_alias.
8170 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8172 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8173 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8174 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8175 (AC_ARG_VAR): ... here.
8176 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8177 target_alias.
8179 Keep a list of all precious variables and process them with one simple
8180 for loop, instead of expanding all commands, or, OTOH, complicated
8181 processing of output of "set".
8182 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8183 variable names in new macro...
8184 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8185 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8186 a loop to assign all ac_env_* and ac_cv_env_* variables.
8187 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8188 to INIT_PREPARE.
8189 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8190 its value to shell variable ac_precious_vars and call
8191 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8192 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
8193 _AC_ARG_VAR_VALIDATE.
8195 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
8196 and the AC_SUBSTs ...
8197 (AC_INIT): ... here.
8199 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
8200 the ac_subst_files section in config.log.
8202 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
8204 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

8209 * tests/c.at (C keywords): Test AC_C_TYPEOF.
8211 Fix problems reported by Nicolas Joly.
8212 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
8213 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8214 They are generated by the Tru64 v5.1B shell.
8216 2005-07-05 Stepan Kasal <kasal@ucw.cz>
8218 Fix my changes from 2005-07-01; reported by Noah Misch.
8219 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8220 description, the macro now accepts only a single tag.
8221 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
8223 Fix cases when the varsions of Autoconf and Autotest don't match.
8224 Reported by Noah Misch.
8225 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
8226 at_top_builddir, for compatibility with older autotest.
8227 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
8228 is not set, use at_top_builddir, for compatibility with older
8229 versions of autoconf.
8231 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8233 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
8234 Problem reported by Patrick Welche.
8236 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8238 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8239 sed substitution command, so that we allow | in program prefixes
8240 and program suffixes. (& is a problem anyway; we're not fixing
8241 that here.)
8242 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8243 configure_input, top_builddir, srcdir, etc.
8244 * lib/autotest/general.m4 (AT_INIT): Likewise, for
8245 PATH_SEPARATOR in AUTOTEST_PATH.
8247 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
8249 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
8250 for loop over config.site files using `set', to allow
8251 directory names containing IFS characters.
8253 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
8255 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
8256 directories with weird names. Apparently some people like living
8257 on the edge. However, improve the test that "pwd" actually does
8258 report a name for the working directory.
8259 * NEWS: Remove the claim that we test for funny chars in dir names.
8261 2005-07-01 Stepan Kasal <kasal@ucw.cz>
8263 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
8264 replaced ...

8273 about #include <config.h>.
8274 (Generic Functions): Mention the Gnulib project.
8275 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
8277 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
8278 document to output the default config_* lists to config.status.
8279 Don't recognize option --file, if the functionality is not there.
8280 Likewise for --header; moreover, recognize --he and --h as shortcuts
8281 for --help in that case.
8283 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8284 matches the order of execution. No code changed.
8286 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8288 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
8289 single-quoted -cmdline argument in Portland Group compiler.
8290 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8292 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>

8299 descriptors to child processes; reported by Norman Gray.
8301 2005-06-29 Stepan Kasal <kasal@ucw.cz>
8303 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
8305 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
8306 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8307 (AC_SUBST): Call it.
8308 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8309 the directory specific variables; but don't call it for configure_input.
8311 2005-06-28 Derek Price <derek@ximbiot.com>
8313 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8314 addition.
8316 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8318 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
8319 directory have inherent problems with special characters like spaces,
8320 due to limitations in Make syntax. Problem reported by Alexandre
8321 Duret-Lutz.
8322 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
8323 Also, fix Tru64 porting problem with shell patterns,

8335 from Justace Clutter.
8336 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8337 variable into diagnostic. Make the diagnostic an error, not a warning,
8338 because we really don't support spaces and suchlike in dir names.
8339 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8340 Don't worry about backslashes in srcdir; it can't happen now.
8341 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8342 Simplify ac_optarg handling.
8343 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8351 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
8353 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8354 that '\|' is not allowed in BREs; recommend using newline separated
8355 list of patterns instead of multiple -e options.
8357 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8359 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8365 2005-06-21 Stepan Kasal <kasal@ucw.cz>
8367 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8368 b, t, r, w commands require single space, while : cannot have any.
8369 (Special Shell Variables): Fix sed code this in the example.
8370 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8371 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8373 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
8374 expand to the empty list. Don't use two pairs of m4_changequote,
8375 it's not necessary.
8377 2005-06-20 Derek Price <derek@ximbiot.com>
8379 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8381 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8383 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8384 * doc/autoconf.texi:
8385 Don't mention Solaris versions so much, if a
8386 problem is common to all extant versions of Solaris. Say "SunOS
8387 4" instead of "SunOS" for SunOS 4.
8388 (awk): Mention more of the limitations of traditional Awk.
8389 (cat): Don't talk about cat -v.
8391 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
8393 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
8394 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
8395 but the implementation is entirely different and is designed
8396 to be compatible with glibc strverscmp.
8397 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
8399 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8400 on Mac OS X 10.4 reported by Peter O'Gorman in:
8401 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
8402 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8403 Use shell builtins rather than 'expr', to work around expr bug.
8405 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8407 * doc/autoconf.texi: "filesystem" -> "file system".
8408 "behaviour" -> "behavior".
8409 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8410 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8411 as per POSIX.
8412 * lib/m4sugar/m4sh.m4: Likewise.
8413 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8414 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8416 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8417 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8418 to update the man page. That way, we don't have to check in new
8419 man pages every month.
8421 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8422 quotes and backslashes. Patch from Derek Price.

8427 AS_TR_SH.
8429 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8431 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8432 -u, since it outputs chatter if the input files are the same.
8433 Problem reported by Ralf Menzel.
8435 2005-06-08 Derek Price <derek@ximbiot.com>
8437 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8438 renaming them since they are about to be redefined anyhow.
8440 2005-06-08 Derek Price <derek@ximbiot.com>
8442 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8443 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8444 Move m4_undefine to alphabetical order.
8446 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8448 * README: Recommend GNU M4 1.4.3 or later.
8449 * doc/autoconf.texi (Introduction): Likewise.
8450 Reword to avoid some formatting glitches.
8451 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8452 Clarify explanation of HP compiler bug.
8453 Redo example output tp match current CVS snapshot.
8454 Use @example.org in email addresses when the examples
8455 might get inadvertently cut-and-pasted into user code.
8456 Remove example of autom4te usage that doesn't seem to work now.
8457 Use modern AC_INIT (except when the example is meant to be
8458 shown with Autoconf 2.13).
8459 Update ksh info for Solaris 9 and later.
8460 KB -> kB.
8461 Modernize description of Automake versions a bit.
8462 Don't claim a future version of Autoconf is near.

8465 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8467 * doc/autoconf.texi: Add [] to examples, so that the manual
8468 follows its own advice about quoting better.
8469 Reword to avoid some formatting glitches.
8470 * doc/installt.exi: Reword to avoid some formatting glitches.
8472 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8473 Tru64 ksh pattern matching bug. Reported against Libtool by
8474 Albert Chin <libtool@mlists.thewrittenword.com> and
8475 Nicolas Joly <njoly@pasteur.fr>.
8477 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8479 m4_cdr of one-member list was [[]] (one-member list containing an
8480 empty string) instead of [] (an empty list. Callers were skewed to
8481 match this misbehaviour. As a consequence of this:
8482 - m4_foreach([x], [], [foo]) expanded to `foo', while
8483 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8484 This bug has been fixed:
8486 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8487 expand to an empty string; print error msg if called without
8488 an argument list.
8489 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8490 misbehaviour; handle [] and [[]] correctly.
8492 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8494 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

8496 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8498 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8500 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8501 swallow records with more than 99 fields.
8502 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8503 parse the long line.
8505 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8507 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8508 swallow literals longer than 399. Reported by Ralf Wildenhues.
8509 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8510 to workaround this limitation.
8512 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8514 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8515 to gfortran, and make these the first two compiler names
8516 checked (following the general autoconf preference for gcc).
8518 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8520 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8521 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8522 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8524 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8526 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8527 expression of unbounded size when processing the --list
8528 option. This runs afoul of a limit of 399 bytes per regular
8529 expression on AIX. Problem reported by Ralf Wildenhues.
8531 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
8533 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
8534 * doc/autoconf.texi (Particular Headers): Reword example
8535 for multiline stdbool replacement.
8536 (Setting Output Variables): Reword text a bit. Don't
8537 give all the details about |#_!!_#|.
8538 Reword description of line replacement.
8540 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8542 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8543 now contain newlines, and substituted files must be referenced on
8544 a line alone; the sed scripts to substitute them are now very
8545 different.
8546 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8547 commands can be put in a sed script portably.
8548 * doc/autoconf.texi (Setting Output Variables): Document above
8549 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8550 use of multiline substitution.

8560 * tests/local.at: Don't attempt to check for negated character
8561 classes in shell scripts. The test was too brittle.
8563 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8565 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8566 * doc/autoconf.texi (Limitations of Builtins): Document this
8567 limitation.
8569 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8571 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8572 common code; used in many places in the tree.

8579 messages when ac_unique_file is not found.
8580 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8581 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8582 commands, for consistency with AC_MSG_ERROR and such.
8584 * bin/autoconf.as: Make more use of "shift 2" in option processing.

8594 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8596 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8597 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8598 (ac_top_builddir): ... this ...
8599 (ac_top_build_prefix): ... to this; the old name is also kept, for
8600 backward compatibility.
8601 (ac_top_builddir_sub): New variable, without the trailing slash,
8602 always nonempty.
8603 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8604 * doc/autoconf.texi (Configuration Actions): Rename
8605 ac_top_builddir to ac_top_build_prefix.
8606 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8607 at_top_builddir to at_top_build_prefix.

8615 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8617 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8618 argument to m4_foreach. I guess it was necessary in the past,
8619 but I think it's a no-op now.
8621 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8623 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8624 ``cat <<_ACEOF'' commands to one.
8625 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8626 * lib/autoconf/status.m4: On various places, use expr instead of
8627 ``echo|sed.''
8628 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8629 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8630 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8631 a range.
8632 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8633 the wrong patterns between ``case'' and ``esac.'' The previous
8634 code had false positives.
8636 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8638 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8639 as on 2005-05-02.
8640 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

8703 quoting rules. Problems noted by Stepan Kasal.
8704 Also, throughout this document, be more careful about white space.
8705 "blank", "white space", and "space" all have different meanings
8706 and we should be careful to say what we mean.

8757 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8758 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8759 comment and reduce m4_default([foo], []) to [foo].
8760 (m4_strip): Update the explanation.
8762 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8764 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8765 Remove core.conftest.* too; it's generated by Tru64 5.1.
8766 Problem reported by Jennis Pruett.
8767 * lib/autoconf/functions.m4
8768 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8769 Don't bother to remove core files; AC_RUN_IFELSE should do that
8770 for you.
8772 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8774 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8783 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
8784 the comment.
8786 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>

8791 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8793 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8794 as well as configure.in. Problem reported by Gregorio Guidi.
8796 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8798 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8799 pattern for alloca snippet.

8809 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8811 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8812 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8814 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8816 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8817 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8818 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8819 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8820 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8822 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8824 * NEWS: The configure command now warns you if you attempt to use
8825 a directory whose name contains a special character like space,
8826 newline, or "\".
8827 * doc/autoconf.texi (Installation Directory Variables): Allow
8828 "," in file names. Do not use \@; it's not a portable regexp.
8829 * bin/Makefile.am (edit): Likewise.
8830 * lib/Makefile.am (edit): Likewise.
8831 * tests/Makefile.am (edit): Likewise.
8832 * tests/semantics.at: Likewise.

8836 * doc/autoconf.texi (File System Conventions): Warn about
8837 unportable file names.
8838 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8839 (AC_INIT): Use it.
8840 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8841 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8842 ac_pwd, and quote srcdir.
8843 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8845 * doc/autoconf.texi: Fix some systematic formatting problems.
8846 ".)" needs a following @: if not at the end of a sentence, and
8847 similarly for "!)". "etc." should be preceded by a comma.
8848 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8850 2005-03-22 Bruno Haible <bruno@clisp.org>
8852 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8853 argument is often called 'build-aux'.
8855 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8857 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8858 macro AC_TRY_LINK is obsolete.
8859 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8860 `AC_CONFIG_FILES'.
8862 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8864 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8865 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8866 from a Common Lisp's `cl'.
8867 (AC_PROG_CXX): Behave according to the documentation: don't
8868 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8869 make the variable CCC precious; use `cl.exe', not `cl'.
8871 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8872 Alexandre Duret-Lutz <adl@gnu.org>
8874 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8875 /dev/null, as "configure" shouldn't read stdin, and this insulates
8876 us from problems (e.g., when testing for "cl"). Also, do this
8877 redirection before invoking "hostname" or "uname", and keep the
8878 original input stream available via...
8879 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8880 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8881 bother with "</dev/null" since it's now done at the top of
8882 'configure'.
8883 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8884 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

8888 * tests/base.at (Input/Output): New test.
8890 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8892 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8893 newline if neither \c nor -n work, as that would output two
8894 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8896 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8898 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8899 This causes that any required macros inside will get before the if.
8900 * doc/autoconf.texi (autom4te.cache): A typo.
8902 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8904 Undo previous change, except keep the change to
8905 lib/autoconf/programs.m4 that replaced grep with shell
8906 pattern-matching. This is because net-snmp configure reads stdin.
8907 Reported by Noah Misch.
8909 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8911 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8912 from /dev/null, as "configure" shouldn't read stdin, and this
8913 insulates us from problems (e.g., when testing for "cl").
8914 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8915 before invoking "hostname" or "uname".
8916 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8917 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8918 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8919 "</dev/null" since it's now done at the top of 'configure'.
8920 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8921 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8922 Also, replace grep with shell pattern-matching, to save a process.
8924 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8926 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8927 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8928 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8929 compiler.
8931 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8933 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8934 grep -q isn't portable. Improve grep -s explanation.
8935 Problem reported by Dan Manthey.
8937 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8939 * doc/autoconf.texi (Special Shell Variables): Clarify
8940 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8942 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8944 * doc/autoconf.texi: Use @acronym for DJGPP.
8945 Fix some @code's that should have been @env's, and vice versa.
8946 Sort environment variable names.
8947 Mention that shells no longer inherit IFS.
8948 Don't recommend PATH_SEPARATOR=';' so strongly.
8949 Mention that $RANDOM might expand to the empty string.
8950 "symlink" and "soft link" -> "symbolic link".
8951 Improve mktemp description (reported by Bruno Haible).
8953 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8955 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8956 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8957 Likewise.
8958 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8959 Likewise.
8961 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8963 * NEWS: Mention AT_COPYRIGHT.
8965 * tests/local.at (AT_CMP): Use diff directly on input files rather
8966 than copying them.
8968 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8969 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8971 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8972 and Paul Eggert <eggert@cs.ucla.edu>
8974 * tests/autotest.at (Empty test suite): New test.

8981 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8982 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8983 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8984 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8985 (Standard regular expressions): New test.
8986 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8987 excess test name quoting.
8988 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8989 CPPFLAGS to `configure' instead of setting it in `configure'.
8991 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8992 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8993 on some platforms.
8995 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8996 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

9004 * tests/c.at (Extensions): Do not exit early.

9024 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
9026 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
9027 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
9029 Try not to generated lines of unlimited length, as POSIX places a
9030 2047-byte limit on line length of portable text files.
9031 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
9032 Use newline as a separator, not space.

9035 space.

9039 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
9040 as_func_*. Add test to check whether positional parameters
9041 are restored after function return.
9043 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
9045 * doc/autoconf.texi (Special Shell Variables): Mention _,
9046 BIN_SH, DUALCASE. Say that variables other than "status" are safe
9047 if they contain a lower-case letter. The DUALCASE problem was
9048 reported by Ralf Wildenhues.
9050 * bin/autoconf.as: Don't exit with status 0 after write failure
9051 with --help or --version.
9052 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

9058 Unicos 9 sed limitations.
9059 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

9061 Fortran 95 (newer Crays).
9063 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
9065 * man/Makefile.am (.x.1): Go back to the simple solution, but take
9066 care to echo the commands, so the user knows what's going on.
9067 Modified from a suggestion by Stepan Kasal.
9069 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

9076 * doc/install.texi (Defining Variables): Likewise.
9077 Based on a proposed patch by Ralf Wildenhues.
9079 * man/Makefile.am (.x.1): Make sure the required generated files
9080 are up to date. Problem and original solution proposed by Stepan Kasal.
9081 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
9082 implicit-man-prerequisites): New rules, used by the above.

9088 2005-01-29 Stepan Kasal <kasal@ucw.cz>
9090 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9091 Update the long comment explaining it.
9093 m4_require no longer writes an ``is required by'' line to the
9094 execution stack. It contains only one bit of non-redundant
9095 information: that the macro was required, not called. And even
9096 this bit is useless in most situations: have you ever met a macro
9097 which both calls and requires the same macro?
9099 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9100 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9101 macro.
9102 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9103 (m4_expansion_stack_pop): Remove the misplaced comment.
9104 (m4_require): Don't put the ``is required by'' line to the
9105 execution stack; slightly improve the out-of-a-defun error message.
9106 (_m4_divert_grow): New macro, counter for the temporary diversions.
9107 (_m4_require_call): Use it.
9108 * tests/m4sugar.at (m4_require): Expect output without the
9109 ``is required by'' messages.
9111 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9113 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
9114 rather than x for expr.
9116 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
9117 this is safe.
9118 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

9130 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
9131 from masters, so that FileUtils.pm's update_file provide --force
9132 support.
9133 * bin/autoheader.in: Pass $force to update_file so that
9134 config.h.in is always recreated when --force.
9136 2005-01-24 Stepan Kasal <kasal@ucw.cz>
9138 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
9140 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9142 * doc/autoconf.texi (Limitations of Builtins): Clarify that
9143 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
9145 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
9147 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
9148 Warn about newline stripping in `` and $(). Update Solaris
9149 version to 9.
9150 (Limitations of Builtins): Use expr "X...", not expr "x...", as
9151 X insulates us from future changes to Posix.
9152 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
9153 stripping.
9155 2005-01-19 Stepan Kasal <kasal@ucw.cz>
9157 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

9173 ulongval to be static, to avoid unwanted GCC warning. Problem
9174 reported by Michael Jennings via Daniel Reed; see
9175 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
9177 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
9179 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

9184 new variables.
9186 2005-01-04 Noah Misch <noah@cs.caltech.edu>
9188 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
9189 not seem to work, assume it does set $(MAKE).
9190 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
9192 2005-01-03 Stepan Kasal <kasal@ucw.cz>
9194 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

9200 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
9201 (_m4_divert_n_stack): New macro; the expansion is
9202 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
9203 otherwise.

9519 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9520 "char c = '\200';" rather than "char c = 0x80;" as the

9670 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9671 texinfo.tex for now (done by hand now).
9672 * Makefile.maint (wget_files, cvs_files):
9673 Remove ansi2knr.c; nobody uses it.
9674 (ansi2knr.c-url_prefix): Remove.
9675 (cvs-update): Fix test for failure. I don't know why it ever
9676 worked...
9678 * doc/autoconf.texi: Update URLs, some of which went stale.
9679 Use @uref rather than @href.
9681 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9682 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9684 * config/config.guess, config/config.sub, config/elisp-comp,
9685 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9686 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9688 * NEWS, TODO, configure.ac, bin/autoscan.in,
9689 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
9690 doc/install.texi, lib/Autom4te/Configure_ac.pm,

9694 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
9695 tests/tools.at, tests/torture.at:
9696 Use "file name" rather than "filename" or "path",
9697 to be consistent with the terminology of the GNU coding standards.
9699 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9701 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9702 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9703 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9704 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9706 More fixes to support spaces in the name of the build directory.
9707 This isn't a complete fix but it's an improvement.
9709 * bin/autoconf.as (autom4te_options): New var.
9710 Use it instead of appending to AUTOM4TE, so that we can allow
9711 spaces in the build directory's absolute name.
9712 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9713 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9714 AT_CHECK_NOESCAPE): Likewise.
9715 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9716 main program): Likewise.
9718 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9720 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
9721 From Ralf Corsepius in:
9722 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
9724 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
9726 * doc/autoconf.texi (Function Portability): Document isinf and
9727 and isnan. From a suggestion by Kevin Ryde.
9729 * lib/Autom4te/General.pm (END): Return correct exit status even
9730 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9732 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9734 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9735 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9736 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9738 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9740 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9741 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9742 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9743 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9744 * lib/autom4te.in (Automake-preselections): Preselect
9745 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9747 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9749 * lib/autom4te.in (Automake-preselections): Preselect
9750 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9751 trace them.
9753 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9755 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9756 Tru64.
9757 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9758 Document problem with "`""`" in pdksh POSIX mode.
9760 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9762 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9763 with pdksh, too. Problem reported by Patrick Welche via
9764 Gary V. Vaughan.
9765 * doc/autoconf.texi (Shellology): Note that set -o posix is
9766 useful for pkdsh, too.
9768 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9770 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9771 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9772 Don't fail if ENV or BASH_ENV is readonly.
9773 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9774 etc. are read only. Problem reported by Ludovic Courtes.
9776 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9778 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9779 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9780 (trivial change)
9782 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9784 * doc/autoconf.texi (File System Conventions): Warn about
9785 names like "aux". Problem reported by Eric Blake.
9787 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9788 by zero instead of array size, so that we can use any arithmetic
9789 constant expression (instead of requiring an integer constant
9790 expression). This allows us to test expressions like DBL_MAX <
9791 LDBL_MAX, which didn't conform to the C standard using the old
9792 method.
9793 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9794 now that we can do floating-point tests at compile time.
9796 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9798 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9799 and LDBL_EPSILON, as the resulting expression isn't an
9800 integer constant expression and violates the C standard.
9801 Problem reported by Nelson H. F. Beebe. Also, check
9802 for "L" suffix, and check that long double doesn't have
9803 worse range or precision than double, that mixed-mode
9804 arithmetic doesn't generate a diagnostic, that double
9805 constants fit in long double.
9807 2004-06-03 Kevin Ryde <user42@zip.com.au>
9809 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9810 malloc(0) and realloc(NULL,size).
9812 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9813 Bob Proulx.
9815 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9817 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9818 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9819 by Jim Meyering.
9821 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9823 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9824 can be rewritten using if-then-else. Suggested by Bruno Haible.
9826 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9828 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9829 Problem reported by Stepan Kasal.
9831 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9833 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9834 change). Patch reported by Ralf Wildenhues in
9835 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9837 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9838 function F exists if the compiler and linker let you compile an
9839 expression like (F != 0). Recent versions of GCC optimize away
9840 the reference to F in that case, since every function address must
9841 be nonzero, so the link succeeds even if F does not exist.
9842 Problem reported by Manu in
9843 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9845 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9846 "Unix". Many uses changed.
9847 (Limitations of Builtins): Explain better why the ! command isn't
9848 portable.
9850 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9852 * lib/autom4te.in (Automake-preselections): Preselect
9853 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9855 2004-05-19 Kevin Ryde <user42@zip.com.au>
9857 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9858 referencing AC_FUNC_STRERROR_R.
9860 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9861 note pessimistic assumption when cross compiling.
9863 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9865 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9866 (until 2004) invoked subcommands with sh -e, contra POSIX.
9867 Reported by Kevin Ryde.
9869 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9871 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9872 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9873 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9874 `test -f " /usr/bin/grep"', which _always_ failed.
9875 (AC_PROG_SED): Ditto bogus PATH fix.
9876 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9877 requires that grep correctly supports _multiple_ `-e' options, rather
9878 than stating only that grep should accept `-e'.
9880 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9882 Port to C99, which requires that 'exit' be declared.
9884 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9885 to ensure that stdlib.h is included.
9886 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9887 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9888 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9889 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9890 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9891 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9892 when using 'exit' in a test; C99 requires that 'exit' be declared.
9894 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9896 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9897 now prefers 'grep' implementations that accept -e.
9898 (Limitations of Usual Tools): Describe problems of traditional
9899 egrep and fgrep with long input lines, and of traditional grep
9900 with -e.
9901 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9902 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9903 All callers changed. Append /usr/xpg4/bin to the PATH, for
9904 Solaris.
9905 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9906 the user with complaints about multiple -e options.
9907 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9908 Define it with AC_PROG_GREP.
9909 * configure.ac (AC_PROG_GREP): Add.
9910 * lib/freeze.mk (GREP): New macro.
9912 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9914 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9915 a possible candidate only after all others fail, rather than
9916 consulting it first. This improves backward compatibility by
9917 better reflecting the way shell selection occurred in previous
9918 versions of Autoconf, and should help to avoid triggering latent
9919 problems in other packages, such as the one in Automake where zsh
9920 is not handled robustly:
9921 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9922 Although it is not Autoconf's responsibility to work around
9923 problems in Automake, it nevertheless makes sense to avoid
9924 introducing unnecessary incompatibilites.
9926 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9927 Gary V. Vaughan <gary@gnu.org>
9929 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9930 how deeply nested we are when a suitable tool is found, set the
9931 ac_path_TOOL_found flag.
9932 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9933 nested we are in this macro. Break out of all 3 nested loops if
9934 ac_path_TOOL_found is set.
9936 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9938 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9939 of the _AS_PATH_WALK loop too if GNU flavor is found.
9941 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9943 * doc/autoconf.texi (Limitations of Make): Update documentation
9944 for `$<'. New entry `Long lines', based on a report from Simon
9945 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9946 paragraph about DJGPP, based on a mail from Richard Dawe.
9948 2004-04-20 Paul Eggert <eggert@twinsun.com>
9950 * tests/c.at (C keywords): Don't assume that GCC supports
9951 "restrict" and "inline", as sufficiently-old GCC versions do not
9952 (also, GCC configured to be in pedantic C89 mode does not).
9953 Problem reported by Sumit Pandya in:
9954 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9956 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9957 consider -g to work if it generates warnings when plain compiles
9958 don't. Problem reported by Braden McDaniel in:
9959 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9961 * doc/autoconf.texi (Slashes): New section, to document a problem
9962 reported by Jim Meyering in:
9963 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9965 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9966 linker output files before linking, to work around IRIX 6 linker bug.
9967 Problem reported by Rainer Orth in:
9968 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9970 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9972 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9973 best tool so far counter rely on the tool path variable name to
9974 avoid checks for one tool being affected by the results of running
9975 the length check on a previous tool.
9977 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9978 match expression argument, as different greps have different
9979 regular expression flavours.
9980 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9981 literals.
9982 (AC_PROG_EGREP): Pass 'EGREP$'.
9983 (AC_PROG_GREP): Pass 'GREP$'.
9985 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9987 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9988 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9990 2004-03-29 Paul Eggert <eggert@twinsun.com>
9992 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9993 Types, Specific Compiler Characteristics, System Services,
9994 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9995 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9996 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9997 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9998 Likewise.
9999 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
10000 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
10001 AC_TYPE_OFF_T): Likewise.
10002 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
10003 Likewise.
10005 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
10006 pacify libtool 1.5.2. Fix quoting problems in sed command.
10008 2004-03-28 Paul Eggert <eggert@twinsun.com>
10010 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
10011 now defines HAVE_DECL_TZNAME if it is declared, when
10012 HAVE_STRUCT_TM_TM_ZONE is not defined.
10013 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
10014 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
10015 for HAVE_TZNAME.
10017 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
10019 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
10020 superfluous backslashing of quotes (") in sed expressions;
10021 thanks to Paul Eggert.
10023 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
10025 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
10026 Fortran compiler is ifort, also added pghpf; thanks to Nelson
10027 H. F. Beebe for the bug report.
10029 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
10031 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
10032 quoted -cmdline argument in Portland Group compiler (bug
10033 reported by Jeffrey J. Barteet).
10035 2004-03-25 Kevin Ryde <user42@zip.com.au>
10037 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
10038 (Run Time): ... here, where it's now mentioned.
10040 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
10042 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
10043 inherits from language Autoconf-without-aclocal-m4.
10044 (Customizing autom4te): Adjust example; the cache must now be
10045 disabled for language Autoconf-without-aclocal-m4.
10047 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
10048 Nathanael Nerode <neroden@twcny.rr.com>
10050 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
10051 AC_CHECK_TOOLS): Warn if a cross-tool is found without
10052 a prefix.
10053 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
10054 AC_CHECK_TARGET_TOOLS): New macros.
10055 * doc/autoconf.texi (Generic Programs): Document
10056 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
10057 AC_CHECK_TARGET_TOOLS, and warn for future changes
10058 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
10059 AC_CHECK_TOOLS.
10060 (Specifying Names): Document the reason for these future
10061 behavioral changes.
10062 * tests/mktests.sh: Do not generate tests for the
10063 new macros.
10064 * NEWS: Document these changes.
10066 * doc/autoconf.texi: Avoid macros with unbraced arguments,
10067 they make TeX hang up.
10069 2004-03-15 Paul Eggert <eggert@bogus.example.com>
10071 * NEWS: New macro AC_CHECK_ALIGNOF.
10072 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
10073 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
10074 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
10075 vowel.
10076 (AC_CHECK_ALIGNOF): New macro.
10077 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
10078 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
10079 those for sizeof.
10081 2004-03-03 Paul Eggert <eggert@twinsun.com>
10083 * bin/Makefile.am (edit): Don't use $< in a context where
10084 POSIX doesn't require support for it. Use $@.in instead.
10085 Problem reported by Anthony N. Frasso in
10086 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
10087 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
10089 2004-02-23 Gary V. Vaughan <gary@gnu.org>
10091 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
10092 from the next generation of Libtool.

10095 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
10097 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
10098 is not always thread-safe. Report from Nathanael Nerode.
10100 2004-02-18 Paul Eggert <eggert@twinsun.com>
10102 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10103 problem on QNX reported by Stephen Rasku in
10104 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
10106 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10107 $(m4sh_m4f_dependencies); this removes a FIXME.
10108 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10109 (MAINTAINERCLEANFILES): Split into pieces,
10110 one per related section. Add $(srcdir)/wrapper.in.
10112 2004-02-09 Paul Eggert <eggert@twinsun.com>
10114 * doc/autoconf.texi (Setting Output Variables): Emphasize that
10115 AC_SUBST provides no portable way to escape literal newlines.
10117 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10118 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10119 Darwin uses -lcrt2.o and there's little point to cataloging all
10120 the system variants. Partial fix reported by Andreas Waechter in:
10121 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
10122 for bug reported by Nelson H. F. Beebe in:

10125 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
10127 * doc/autoconf.texi (AU_DEFUN): Fix English,
10128 suggested by Paul Eggert.
10129 * lib/autoconf/autoupdate.m4: Correct reference to
10130 acobsolete.m4, suggested by Alexandre Duret-Lutz.
10132 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
10134 * bin/autoupdate.in: Define __file__ so that warnings
10135 refer to the correct file.
10136 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
10137 the behavior of the third argument.
10138 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
10139 correctly the behavior of the third argument. Document
10140 what the three macros that AU_DEFUN defines do. Fix
10141 warning message when the third argument includes $0
10142 (reported by Alexandre Duret-Lutz).
10144 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10145 Eric Sunshine <sunshine@sunshineco.com>
10146 Paul Eggert <eggert@twinsun.com>
10148 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

10150 parameter. Expand _AS_SHELL_FN_SPY.
10151 (AS_INIT_WITH_SHELL_FN): Removed.
10152 (_AS_SHELL_FN_SPY): New macro.
10153 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
10154 macros.
10155 (AS_SHELL_SANITIZE): Remove loop to find better shell
10156 and documentation for the parameter.
10157 (_AS_DETECT_BETTER_SHELL): Move it here.
10158 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
10159 (_AS_RUN): Move it here, support testing with eval.
10160 (AS_REQUIRE_SHELL_FN): Require shell functions when
10161 it is used.
10162 (_AS_LINENO_WORKS): Put around braces, we do not
10163 trigger the bash bug anymore.
10164 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10165 use AS_INIT_WITH_SHELL_FN.
10166 * bin/autoconf.in, tests/wrapper.in: Regenerated.
10168 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10170 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
10171 * doc/autoconf.texi: Don't say that the third parameter
10172 is broken.
10173 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
10174 (AU_DEFUN): Honor the third parameter, create autoupdate
10175 macros with AU_DEFINE.
10176 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
10177 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
10178 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
10179 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
10180 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
10181 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
10182 AC_XENIX_DIR): Likewise.
10183 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
10184 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
10185 * lib/autoconf/status.m4: Remove FIXME.
10186 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
10187 that the macro is not present anymore in the updated
10188 configure.ac.
10189 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
10190 of autoupdate.
10192 2004-01-28 Paul Eggert <eggert@twinsun.com>
10194 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
10195 copyright years.
10196 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
10197 2003 (except 1997) to the list of copyright years. This undoes
10198 the 2003-05-22 change, which removed the older years from the list.
10199 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
10201 2004-01-27 Gary V. Vaughan <gary@gnu.org>
10202 Albert Chin-A-Young <china@thewrittenword.com>
10204 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
10205 grep or ggrep program in PATH that accepts as long lines as
10206 possible.
10207 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
10208 AC_PROG_GREP.
10209 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
10210 egrep and fgrep respectively if $GREP -E/-F don't work.
10211 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10212 _AC_PROG_GREP, and AC_PROG_SED.
10213 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10214 longest input length accepted by a command.
10215 (AC_PROG_SED): Use it.
10216 * doc/autoconf.texi (Particular Programs): Document the changes.
10217 * NEWS: Updated.
10219 2004-01-27 Paul Eggert <eggert@twinsun.com>
10221 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
10222 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10223 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
10224 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
10226 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
10227 bin/autoconf.in, config/Makefile.in, config/config.guess,
10228 config/config.sub, config/install-sh, config/mdate-sh,
10229 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,

10239 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
10240 tests/actypes.at: Regenerate and/or sync with original
10241 sources.
10243 2004-01-26 Paul Eggert <eggert@twinsun.com>
10245 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10246 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10247 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10248 not <inttypes.h>. Problem reported by Tim Mooney in
10249 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10250 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10251 Likewise.
10253 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10254 otherwise "make check" fails because it forbids cmp (I guess
10255 because cmp treats files as binary on DOS-like systems).
10257 * tests/mktests.sh: Update copyright date to 2004, since some tests
10258 have changed in 2004.
10260 2004-01-23 Gary V. Vaughan <gary@gnu.org>
10262 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
10263 non-truncating sed or gsed program in PATH.
10264 * tests/acprograms.at: Add it.
10265 * doc/autoconf.texi (Particular Programs): Document it.
10266 * NEWS: Updated.
10268 2004-01-15 Paul Eggert <eggert@twinsun.com>
10270 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10271 -std1 disables some useful extensions on Tru64. Problem reported
10272 by N. Lichtmaier in
10273 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10275 2004-01-14 Paul Eggert <eggert@twinsun.com>
10277 * doc/autoconf.texi (Programming in M4sh): Document that
10278 AS_MKDIR_P succeeds if the destination is a symbolic link
10279 to an existing directory.
10280 (Limitations of Usual Tools): Note that mkdir -p might not
10281 succeed on symlinks to directories.
10283 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10285 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10286 * bin/autoheader.in: Grammar fix in message.
10287 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10288 Test for dir before calling mkdir -p. (trivial changes)
10290 2004-01-13 Eric Blake <ebb9@byu.net>
10292 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10293 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10295 2004-01-10 Jim Meyering <jim@meyering.net>
10297 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10299 2004-01-09 Paul Eggert <eggert@twinsun.com>
10301 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10302 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10303 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10304 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10305 AC_COMPILE_IFELSE, since we now assume our caller invokes
10306 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10307 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10308 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10309 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10311 2004-01-07 Paul Eggert <eggert@twinsun.com>
10313 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10314 `"'...'"`, as it's confusing (and I suspect it may not work on
10315 some platforms). The code was incorrect anyway, as it assumed
10316 that \$ evaluated to itself in that context. Reported by
10317 Alexandre Duret-Lutz.
10319 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10321 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10322 and _LT_AC_TAGCONFIG.
10324 2004-01-06 Paul Eggert <eggert@twinsun.com>
10326 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10327 example, and add more examples. Reported by Eric Sunshine.
10329 2004-01-05 Paul Eggert <eggert@twinsun.com>
10331 * doc/autoconf.texi (Limitations of Usual Tools):
10332 Remove warning against "rm -fr" introduced yesterday; it
10333 was a false alarm.
10335 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
10336 autoscan, autoupdate, ifnames): Don't use chmod -w.
10337 * lib/Makefile.am (autom4te.cfg): Likewise.
10338 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
10339 "chmod -w".
10341 2004-01-04 Paul Eggert <eggert@twinsun.com>
10342 Paolo Bonzini <bonzini@gnu.org>
10344 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
10345 by doing lineno substitution only on lines containing "$LINENO".
10347 2004-01-04 Paul Eggert <eggert@twinsun.com>
10349 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10350 Use "rm -f" to remove conftest.sed, not plain "rm".
10351 Bug reported by David Relson in
10352 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10354 * Makefile.am (autom4te-update):
10355 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10356 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10357 * doc/autoconf.texi (Guidelines): Likewise.
10358 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
10359 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.
10360 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10361 * lib/autotest/general.m4 (AT_INIT): Likewise.
10362 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
10363 * tests/Makefile.am (clean-local): Likewise.
10364 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
10365 srcdir): Likewise.
10366 * doc/autoconf.texi (Limitations of Usual Tools):
10367 Warn against "rm -fr".
10369 2004-01-03 Paul Eggert <eggert@twinsun.com>
10371 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10372 -c -o might not work. From a suggestion by Kevin Ryde.
10373 (C Compiler, Generating Sources, Limitations
10374 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10375 Don't put '-o' after non-options, as POSIX doesn't allow this.
10376 Mention that cc's name might be gcc or c89 or whatever.
10378 2004-01-04 Kevin Ryde <user42@zip.com.au>
10380 * doc/autoconf.texi: Add various further index entries.
10382 2003-12-29 Paul Eggert <eggert@twinsun.com>
10384 * bin/autoreconf.in (autoreconf_current_directory):
10385 Fix typo: mkdir without umask arg.
10387 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10389 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10390 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10391 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10392 explanation clearer.
10394 2003-12-24 Andreas Schwab <schwab@suse.de>
10396 * doc/autoconf.texi (Default Includes): Fix misspelling of
10397 AC_INCLUDES_DEFAULT.
10399 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10401 * configure.ac: Test if sh -n works.
10402 * configure: Regenerate.
10403 * tests/atlocal.in: Store the result here.
10404 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
10405 tools.at, looking in atlocal's ac_cv_sh_n_works instead
10406 of explicitly testing.
10407 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10408 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10409 * tests/tools.at (Syntax of the shell scripts): Simplify
10410 using AT_CHECK_SHELL_SYNTAX.
10411 (Syntax of the Perl scripts): Remove definition of
10412 AT_CHECK_PERL_SYNTAX.
10414 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10416 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
10417 stderr to /dev/null.

10423 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
10424 Extracted from AS_SHELL_SANITIZE.
10425 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
10426 macros.
10427 (AS_SHELL_SANITIZE): Move reinvocation code from
10428 _AS_LINENO_WORKS, use it to find out if shell
10429 functions work.
10430 (_AS_LINENO_WORKS): Don't find another shell if $LINENO

10443 * config/announce-gen (&print_locations, &print_signatures)
10444 (&sizes): New.
10445 Use them.
10446 No longer rely on Gnus to inline the list of signatures: compute
10447 them on the fly.
10449 2003-11-24 Akim Demaille <akim@epita.fr>
10451 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
10452 override some files.
10453 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
10454 From Debian Autoconf 2.58.
10456 2003-11-24 Akim Demaille <akim@epita.fr>
10458 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote $ac_popdir

10464 * TODO: Remove already done things. Update the part about finding
10465 tools for the target.

10469 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H, AC_DIR_HEADER):
10470 Make wording more consistent.
10471 * lib/autoconf/specific.m4 (AC_CYGWIN, AC_EMXOS2, AC_MINGW32):
10472 Explain the transition better.
10473 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS): Explain
10474 the transition better.
10476 2003-11-24 Paolo Bonzini <bonzini@gnu.org>
10478 * doc/autoconf.texi (Obsoleting Macros): Don't document the third
10479 parameter of AU_DEFUN.
10480 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
10481 (AU_DEFUN): Remove the third parameter, it was not used.
10482 Use AC_DEFUN directly, not AU_DEFINE.
10483 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
10484 the expanded body, consistently with other macros such as AC_USG.
10486 2003-11-17 Paul Eggert <eggert@twinsun.com>
10488 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
10489 into the initial confdefs.h, to work around a bug in NextStep 3.3
10490 patch 3 reported by Eric Sunshine.
10492 2003-11-15 Kevin Ryde <user42@zip.com.au>
10494 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10495 than $target since the latter is not usual, add guidelines on when to
10496 use or not use the system type.
10498 2003-11-12 Derek Price <derek@ximbiot.com>
10500 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

10511 * configure.ac: Bump to 2.59a.
10512 Require 2.59.
10514 2003-11-06 Akim Demaille <akim@epita.fr>
10516 Version 2.59.
10518 2003-11-05 Alexandre Duret-Lutz <adl@gnu.org>
10520 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
10521 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
10522 and ac_abs_top_srcdir are absolute paths.
10523 * lib/m4sugar/m4sh.m4 (AS_SET_CATFILE): Remove misleading comment.

10529 2003-11-05 Kevin Ryde <user42@zip.com.au>
10531 * doc/autoconf.texi (Using Autotest): Avoid @strong{Note: ...}, since
10532 it provokes a warning from makeinfo about looking like a cross
10533 reference in info output.

10661 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10663 2003-10-10 Andreas Schwab <schwab@suse.de>
10665 * bin/autoheader.in: Avoid empty first line in --version and

10677 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10678 -mGLOB_options_string stuff for Intel ifc, which can cause
10679 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10680 pattern-matching instead of grep.

10700 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10702 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10703 cache variable instead of $G77 to decide whether to include -O2,
10704 since $G77 is specific to Fortran 77.

10713 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10714 arguments so that it can be used with syntax identical to
10715 AC_PROG_F77, and so that we can more easily decide to
10716 remove/deprecate the DIALECT optional argument in the future if it
10717 proves troublesome.
10718 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10719 non-freeform-supporting compilers. Document freeform flags.
10721 2003-10-03 Akim Demaille <akim@epita.fr>
10723 * configure.ac: Look for emacs, not macs.
10724 Reported by Eric Sunshine.
10726 2003-10-03 Akim Demaille <akim@epita.fr>
10728 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10729 * bin/autoreconf.in (autoreconf_current_directory): Create the
10730 AUX_DIR if needed, for sake of automake --add-missing etc.
10731 Suggested by Alexandre Duret-Lutz.
10733 2003-10-03 Akim Demaille <akim@epita.fr>
10735 * configure.ac: Quotation and formatting changes.

10758 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
10760 2003-09-30 Akim Demaille <akim@epita.fr>
10762 * config/announce-gen (&print_news_deltas): Extracted from...
10763 (&print_changelog_deltas): here.
10764 (&news_file): Rename as...
10765 (@news_file): this.
10767 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
10769 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10770 have been created when invoking the compiler.

10783 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10784 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10785 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10786 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10788 2003-09-26 Akim Demaille <akim@epita.fr>
10790 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10791 directory for AC_CONFIG_COMMANDS' first argument exists.
10792 This makes valid the invocation of _AC_SRCPATH that follows.
10793 Reported by Eric Sunshine.
10794 * doc/autoconf.texi (Configuration Commands): Adjust.
10796 2003-09-26 Akim Demaille <akim@epita.fr>
10798 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10799 Reported by Ralf Corsepius.
10801 2003-09-26 Akim Demaille <akim@epita.fr>
10803 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10804 arguments.

10806 From Bruno Haible.
10808 2003-09-26 Paul Eggert <eggert@twinsun.com>
10810 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

10813 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
10815 2003-09-26 Akim Demaille <akim@epita.fr>
10817 The test suite are sometimes assigning timings incorrectly.
10818 Reported by Henk Krus.
10819 Diagnosed by Nicolas Joly.
10821 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10822 AT_help_all.
10823 Instead of making AT_help a sequence of assignments to grow
10824 $at_help_all, just make AT_help_all be the growing contents of
10825 $at_help_all, and make a single assignment in...
10826 (AT_INIT): here.
10827 (at_times_skip): Flip the meaning and rename as...
10828 (at_times_p): this.
10829 (AT_INIT): When summarizing the test that ran, remove
10830 $at_times_file after use, and check it is present before trying to
10831 use it.
10833 2003-09-25 Akim Demaille <akim@epita.fr>
10835 Version 2.57d.
10837 * bin/Makefile.am (edit): Handle '@configure_input@'.
10838 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10839 (ifnames): chmod -w.
10840 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10841 executables, not bin/ executables! Otherwise all the magic needed
10842 to find non installed files is turned off. This caused a failure
10843 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10844 as found in its environment (sent by tests/autoreconf): pointing
10845 to bin/autom4te that could not find its files.
10846 * tests/mktests.sh: Force the replacement of generated files, for
10847 the sake of "mv" program that are interactive when overwriting a
10848 -w file.
10849 * config/install-sh: Upgrade from CVS Automake.
10851 2003-09-23 Paul Eggert <eggert@twinsun.com>

10854 versus test -L issues.
10856 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10857 Paul Eggert <eggert@twinsun.com>
10859 Trivial change to support GCC's configuration procedure.
10860 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10861 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10862 about inconsistency if the preprocessor is set to give errors for
10863 any warning.
10864 * doc/autoconf.texi (C Compiler Characteristics): Document this.
10866 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

10892 2003-09-10 Akim Demaille <akim@epita.fr>
10894 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10895 willing to edit the output files.
10897 2003-09-10 Akim Demaille <akim@epita.fr>
10899 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10900 and AC_FC_FREEFORM.
10901 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10902 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10904 2003-09-09 Akim Demaille <akim@epita.fr>

10917 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10918 Improve the accuracy of the wording about obsolescence.
10919 From a suggestion by Ian Lance Taylor in
10920 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10922 2003-09-05 Paul Eggert <eggert@twinsun.com>
10924 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10925 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10927 2003-09-04 Akim Demaille <akim@epita.fr>
10929 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10930 AC_FUNC_WAIT3.
10932 2003-09-04 Akim Demaille <akim@epita.fr>
10934 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10935 (freeze): When exiting, use $exit_code.
10936 * lib/autoconf/fortran.m4: Comment changes.
10938 2003-09-04 Akim Demaille <akim@epita.fr>
10940 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10942 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10944 Add support for newer Fortran dialects. The F77 interface is
10945 unchanged, and continues to support Fortran 77. New FC macros
10946 correspond to all the old F77 macros, with output variables FC,
10947 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10948 available dialect, but older dialects can be specified. There are
10949 new macros AC_FC_SRCEXT to set the source extension, and
10950 AC_FC_FREEFORM to accept free-form source files.
10952 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10953 New macros.
10954 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10955 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10956 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),

10969 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10970 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10971 Rewrite in terms of the above.
10972 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10973 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

10975 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
10977 2003-09-02 Paul Eggert <eggert@twinsun.com>
10979 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10980 Document problems with timestamp resolution that 'make', 'cp -p', and
10981 'touch -r' have.
10983 2003-08-27 Akim Demaille <akim@epita.fr>

10986 output, so that we can track spurious m4sugar output.
10987 * tests/local.at: Require 2.57.
10988 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10989 are defaulted by AT_CHECK anyway.
10990 Use AT_CHECK_AUTOM4TE.
10991 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10992 missing dnl.
10994 2003-08-27 Akim Demaille <akim@epita.fr>
10996 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10997 when -Wobsolete is set.
10998 Set it on by default.
10999 Suggested by Klee Dienes.
11001 2003-08-27 Akim Demaille <akim@epita.fr>
11003 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
11004 documentation.
11005 From Guido Draheim.
11007 2003-08-26 Akim Demaille <akim@epita.fr>
11009 * doc/autoconf.texi (Output): Make clear that one can run code
11010 after AC_OUTPUT.
11012 2003-08-25 Akim Demaille <akim@epita.fr>
11014 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
11015 CVS Bison.
11017 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
11019 * bin/autoreconf.in (parse_args): Do not pass --no-force to
11020 Automake versions prior to 1.8.
11022 2003-08-25 Akim Demaille <akim@epita.fr>
11024 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.
11025 From Ville Karaila.
11027 2003-08-24 Akim Demaille <akim@epita.fr>
11029 * configure.ac: Bump to 2.57c.
11031 2003-08-22 Akim Demaille <akim@epita.fr>
11033 Version 2.57b.
11035 * Makefile.cfg (local-checks-to-skip): New.
11036 * Makefile.maint (local-check): Rename as...
11037 (local-checks-available): this.
11038 (local-check): New.
11040 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
11041 * configure.ac: Require Automake 1.7.6.
11043 2003-08-22 Akim Demaille <akim@epita.fr>
11045 Output stack traces in warnings.
11047 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
11048 Replace the former...
11049 (m4_warn): Pass the call stack to _m4_warn.
11050 * bin/autom4te.in: Adjust to output the call stack.
11051 * tests/m4sugar.at (m4@&t@_warn): Adjust.
11053 2003-08-22 Akim Demaille <akim@epita.fr>
11055 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
11056 * bin/autom4te.in: Adjust.
11058 2003-08-21 Akim Demaille <akim@epita.fr>
11060 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
11061 (&verbose): Remove.
11062 (&getopt): Adjust the note and verb channels, depending upon
11063 --verbose.
11064 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
11065 * bin/autoupdate.in: Adjust.
11066 Use &verb, not &verbose.
11068 2003-08-21 Akim Demaille <akim@epita.fr>
11070 * bin/autoheader.in (&parse_args): Use &parse_warnings and
11071 &parse_WARNINGS.
11072 ($help): Use Autom4te::ChannelDefs::usage.
11073 * bin/autoscan.in: Use Autom4te::ChannelDefs.
11074 * lib/Autom4te/General.pm: Don't export error: you don't own it.
11076 2003-08-21 Akim Demaille <akim@epita.fr>
11078 First stab at preserving warnings between calls to autom4te,
11079 including when the cache is used.
11081 There are still several issues: (i) there are too many runs of m4
11082 (one for include, one for warnings, and some more), (ii) warnings
11083 spreading on several lines are not handled gracefully, (iii) the
11084 code meant to have the call stack display for errors does not work
11085 (its handling should move from m4 to autom4te).
11087 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11088 Use them.
11089 (@preselect): Add m4_warn.
11090 ($exit_status): Remove, use $exit_code.
11091 ($help): Use Autom4te::ChannelDefs::usage.
11092 (&handle_m4): No longer define the m4_warnings.
11093 At each run, extract and report the warnings.
11094 Always cache the result, including if the exit status is on
11095 failure, since if nothing changes, we should result in the same
11096 failure, hence we can use the cache.
11097 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11098 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11099 Remove.
11100 (m4_warn): Redefine as a do-nothing: it is its invocation that
11101 matters, as warnings are now reported via traces.
11102 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11103 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11104 the latter reveals calls to the former.
11106 Adjust the tests.
11108 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
11110 2003-08-21 Akim Demaille <akim@epita.fr>
11112 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
11113 Use them.
11115 2003-08-21 Akim Demaille <akim@epita.fr>
11117 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
11118 forward order.
11119 * lib/Autom4te/ChannelDefs.pm: Doc typos.
11120 (&parse_warnings): Accept a list of warning requests.
11121 (&usage): Return a string, not a side effect.
11122 (cross): New warning category.
11124 2003-08-21 Akim Demaille <akim@epita.fr>
11126 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
11127 (&require_configure_ac): Accept an optional directory argument.
11128 ($configure_ac): Remove.
11129 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
11130 (&catfile): Remove.
11131 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
11132 * bin/autoscan.in: Adjust.
11134 2003-08-20 Akim Demaille <akim@epita.fr>
11136 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
11137 Reported by Alexandre Duret-Lutz.
11139 2003-08-20 Akim Demaille <akim@epita.fr>
11141 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11142 * bin/autom4te: Adjust.
11143 In particular, be Autoconf tools are really silent when properly
11144 working, bind the verbosity of the 'note' channel to $verbose.
11145 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11146 (&xsystem, &contents): Remove, since they are exported by...
11147 * lib/Autom4te/FileUtils.pm: this.
11148 More perldoc.
11149 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
11150 * lib/Autom4te/FileUtils.pm: here.
11152 2003-08-20 Akim Demaille <akim@epita.fr>
11154 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
11155 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
11156 from CVS Automake.
11158 2003-08-20 Akim Demaille <akim@epita.fr>
11160 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
11161 (autom4te-update): New.
11162 * Makefile.cfg (update): Bind autom4te-update.
11164 2003-08-19 Derek Price <derek@ximbiot.com>
11166 * lib/autotest/general.m4: Comment various HELP_* diversions.
11167 (PARSE_ARGS_BEGIN): New section for option parsing related
11168 initialization.
11169 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
11170 package specific options and associated help.
11172 2003-08-19 Akim Demaille <akim@epita.fr>
11174 * config/announce-gen, Makefile.cfg: New.
11175 * Makefile.am: Adjust.
11176 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
11178 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
11180 * lib/autom4te.in (Automake-preselections): Preselect
11181 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
11182 and m4_sinclude.
11184 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
11186 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
11187 (Autoconf-without-aclocal-m4): ... this new language.
11188 * doc/autoconf.texi (autom4te Invocation): Mention
11189 Autoconf-without-aclocal-m4.
11191 2003-08-18 Derek Price <derek@ximbiot.com>
11193 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
11194 RUN-IF-PASS optional arguments.
11196 2003-08-18 Derek Price <derek@ximbiot.com>

11202 * doc/autoconf.texi (Writing testsuite.at): Document defaults for
11203 STDOUT & STDERR arguments.
11205 2003-08-14 Derek Price <derek@ximbiot.com>
11207 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
11208 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
11209 shorter column three. Add DESCRIPTION to log file content.
11211 2003-08-13 Derek Price <derek@ximbiot.com>
11213 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
11214 output.
11216 2003-08-12 Derek Price <derek@ximbiot.com>
11218 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
11219 (AT_CHECK_NOESCAPE): Move core functionality to...
11220 (_AT_CHECK): ...this new macro.
11222 2003-08-07 Derek Price <derek@ximbiot.com>
11224 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
11225 (AT_CHECK_NOESCAPE): ...to this new macro.
11227 2003-07-31 Paul Eggert <eggert@twinsun.com>
11229 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
11230 in Bash 2.01. Problem reported by Brian Gough in
11231 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
11233 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
11235 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
11236 -lcrt1.o, for OS X. (trivial change)
11238 2003-07-07 Paul Eggert <eggert@twinsun.com>
11240 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
11241 inside '#ifndef __cplusplus'. Problem reported by
11242 Bob Friesenhahn.
11244 2003-07-06 Bill Clarke <llib@computer.org>
11246 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
11247 'long', not 'int', for benefit of Sun's recent C++ compilers
11248 (trivial change). See:
11249 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
11250 (This really should be 'intptr_t', not 'long', but that would
11251 take more work.)
11253 2003-06-25 Akim Demaille <akim@epita.fr>
11255 * lib/Makefile.am (autom4te.cfg): Make it read only.
11256 Depend on Makefile since it contains substitutions.
11257 From Paolo Bonzini.
11258 * lib/autom4te.in (args): Add local.at? for Autotest args.
11259 This change was made on autom4te.cfg which is generated.
11260 Reported by Raja R. Harinath.
11262 2003-06-25 Akim Demaille <akim@epita.fr>
11264 * doc/autoconf.texi (Header Portability): sys/mount.h.
11265 From Gareth McCaughan.
11267 2003-06-23 Akim Demaille <akim@epita.fr>
11269 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11270 not all of them. This fixes 1. the fact that when testing
11271 Autoconf there are many many config.log, 2. the incorrect use of
11272 top_srcdir to find config.log.
11273 Don't mix the detailed output of failed test with the summary of
11274 failures. Rather, append detailed log afterwards.
11276 2003-06-23 Akim Demaille <akim@epita.fr>
11278 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11279 always run: output config.log on $at_group_log.
11281 2003-06-23 Akim Demaille <akim@epita.fr>
11283 * tests/torture.at (#define header templates): Don't use quotes in
11284 C++ comments as it puzzles Emacs' sh font-lock-mode.
11286 2003-06-23 Akim Demaille <akim@epita.fr>
11288 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
11289 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
11290 * tests/atspecific.m4: Rename as...
11291 * tests/local.at: This.
11292 * tests/suite.at: Move the globals into...
11293 * tests/local.at: here.
11294 * tests/Makefile.am: Adjust.
11295 * doc/autoconf.texi (testsuite Scripts): Adjust.
11297 2003-06-21 Kevin Ryde <user42@zip.com.au>
11299 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
11300 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
11301 ensuring we add -std1 for full-ANSI.
11303 * doc/autoconf.texi (hdrindex): New macro.
11304 Add index entries for portability of various standard header files.
11306 2003-06-20 Akim Demaille <akim@epita.fr>
11308 * configure.ac: Bump to 2.57b.
11310 2003-06-20 Akim Demaille <akim@epita.fr>
11312 Version 2.57a.
11314 2003-06-20 Akim Demaille <akim@epita.fr>
11316 * bin/autom4te.in: Don't rely on $HOME being defined.
11317 Reported by Marc Espie as PR/233.
11319 2003-06-20 Akim Demaille <akim@epita.fr>
11321 * lib/autotest/general.m4: Use at_times_file only if used.
11322 From Nicolas Joly.
11324 2003-06-20 Akim Demaille <akim@epita.fr>
11326 * config/config.guess, config/config.sub, config/elisp-comp,
11327 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
11328 Update from masters.
11330 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
11332 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
11333 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
11334 (TEST_SCRIPT): New diversion.
11335 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
11336 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11337 (AT_INIT): Support for expected failures.
11339 2003-06-02 Akim Demaille <akim@epita.fr>
11341 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
11342 changes.
11343 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
11344 Autoconf nor Automake.
11345 (&contents): New, from Automake.
11346 PODify.
11348 2003-05-28 Paul Eggert <eggert@twinsun.com>
11350 * NEWS, doc/autoconf.texi (Particular Functions),
11351 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11352 is the inverse of localtime.
11354 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
11356 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11357 (handle_exec_errors): New function. Work around $! being
11358 altered by WEXITSTATUS.
11359 (xqx, xsystem): Use handle_exec_errors.
11361 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11363 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11364 Do not call `_exit()', simply modify `$?'.
11365 (xsystem): Reset $! before running system, and check it afterward.
11366 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11367 63 for version mismatches.
11369 2003-05-23 Akim Demaille <akim@epita.fr>
11371 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11372 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11373 the middle of a line).
11374 * lib/m4sugar/m4sugar.m4: Likewise.
11375 Remove useless spaces in comments.
11377 2003-05-23 Akim Demaille <akim@epita.fr>
11379 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11380 exit 63, so that we (or Automake's "missing") can tell the
11381 difference with a plain failure.
11382 * doc/autoconf.texi (Notices): Adjust.
11384 2003-05-23 Akim Demaille <akim@epita.fr>
11386 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11387 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
11388 White spaces cleanup.
11390 2003-05-22 Jim Meyering <jim@meyering.net>
11391 Paul Eggert <eggert@twinsun.com>
11393 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11394 Remove `#include <stdlib.h>' from the list; we should never
11395 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11396 resulting namespace pollution would cause other tests to fail.
11397 Configure scripts run with some older versions of g++ and HP's
11398 aCC would fail due to such an #include. Problems reported by
11399 Matthew Mueller in <http://bugs.debian.org/120704> and by
11400 Keith Bostic in
11401 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11402 In the test, use the test declaration before including <stdlib.h>,
11403 as that's closer to how it'll be used.
11405 2003-05-23 Akim Demaille <akim@epita.fr>
11407 * doc/autoconf.texi (Header Portability): ucred.h.
11408 From Ian Redfern.
11410 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11412 Overhaul Autotest's logging: generate separate log files
11413 in testsuite.dir/NNN/testsuite.log, and append them to
11414 testsuite.log instead of re-running the test verbosely.
11416 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11417 file descriptor, write 0 to at_status_file instead of setting
11418 at_status=0, initialize some new variables (at_status_file,
11419 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11420 to rerun the tests, instead append the at_group_log to the
11421 at_suite_log when a test fails.
11422 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11423 with the AS_MESSAGE_LOG_FD redirected to stdout.
11424 (AT_CLEANUP): save the output status in $at_status_file
11425 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11426 its original place.
11427 (AT_CHECK): since tests are run with a redirected stdout,
11428 and used to be re-run in verbose mode, turn some $at_verbose
11429 into echo, and don't redirect the output of testing stdout
11430 and stderr.
11432 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11433 the name of the debugging directory and information about
11434 its contents.
11436 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11438 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
11439 parameter.
11441 2003-05-22 Akim Demaille <akim@epita.fr>

11553 2003-05-06 Akim Demaille <akim@epita.fr>

11556 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11557 by aclocal.m4 is changed it might require the importing of another
11558 m4 extension file, i.e., aclocal must be run.
11560 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11561 (&parse_args): Use --force with aclocal if required and supported.

11579 (AT_CLEANUP): Add `;' to end of at_help_all.
11580 (AT_INIT): Allow --keywords to be specified more than once. When
11581 grepping $at_help_all for keywords, use the field and keyword
11582 seperators to ensure a complete keyword match. Alter at_prev handling

11587 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11588 align better with others. I also made some of the individual

11661 * tests/torture.at (Configuring subdirectories): Require aclocal

11810 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11811 innocuous variant befor including <limits.h> or <assert.h>. This
11812 works around a bug reported by Albert Chin: HP-UX 11i
11813 (and earlier versions) have a <limits.h> that declares
11814 gettimeofday and many other functions.
11816 2002-12-03 Paul Eggert <eggert@twinsun.com>

11826 not optimized away in AIX. This should fix the bug reported by
11827 Martin Frydl in
11828 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11830 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11831 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11832 defined, to support freestanding compilers. This should fix the
11833 bug reported by Momchil Velkov in
11834 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11836 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11837 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11872 * Makefile.maint: Sync with Bison, i.e.:
11873 (po-check): Scan .l and .y files instead of the
11874 .c and the .h files that they generate. This fixes the bug
11875 reported by Tim Van Holder in:
11876 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11877 Look for N_ as well as for _. Try to avoid matching #define for

11898 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q

11934 2002-11-05 Akim Demaille <akim@epita.fr>
11936 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11937 Remove.
11938 We _have_ to stop using the old compatibility scheme that tried to
11939 avoid useless backslashes because Libtool 1.4.3 contains a
11940 AC_DEFINE([error_t], [int],
11941 [Define to a type to use for \`error_t' if it is not
11942 otherwise available.])
11943 We _have_ to quote the single quote and backslashes with \. The
11944 old compatibility scheme saw that ` was backslashed, and therefore
11945 did not quote the single quote. Hence before this patch, Autoconf
11946 was not compatible with Libtool.
11948 2002-11-04 Paul Eggert <eggert@twinsun.com>

12337 Reported by Alexandre Duret-Lutz.
12339 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12343 (&freeze): Use &error.
12344 (&up_to_date): If a file that was included according to the cache
12345 is no longer there, then the output is out dated.

12359 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12360 if some file was changed instead of `print'.
12361 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

12394 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
12395 file name to enable parallel executions.
12396 From Sam Varshavchik.
12398 2002-10-08 Akim Demaille <akim@epita.fr>
12400 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12401 aclocal invocation, as Gettext macros might not be visible to
12402 aclocal.
12403 Instead of blindly running autopoint, scan configure.ac (not the

12405 Reported by Paul D. Smith.
12407 2002-10-08 Paul Eggert <eggert@twinsun.com>
12409 Work around problems found when POSIXLY_CORRECT=1 is set.
12410 None of this seems to have anything to do with POSIX, really,
12411 but it's how Perl getopt works.
12412 * bin/autom4te.in (parse_args): Configure GetOpt with
12413 "permute", too.
12414 * doc/autoconf.texi (Invoking autom4te):
12415 --warning -> --warnings.
12416 * lib/autom4te.in: --warning -> --warnings.
12418 2002-09-28 Akim Demaille <akim@epita.fr>
12420 * doc/autoconf.texi (autom4te.cache): New section.
12422 2002-09-28 Akim Demaille <akim@epita.fr>
12424 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
12425 (Automake-preselections): Update.
12426 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
12428 2002-09-28 Akim Demaille <akim@epita.fr>
12430 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
12431 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
12432 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12433 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12435 2002-09-28 Akim Demaille <akim@epita.fr>
12437 * tests/torture.at (Configuring subdirectories): Be robust to
12438 users who use config.site to require for a cache: in this case,
12439 the two last configure runs, using two different sets of
12440 arguments, trigger a legitimate error.
12442 2002-09-28 Akim Demaille <akim@epita.fr>
12444 * tests/m4sh.at (Functions Support, Functions and return Support):
12445 New.
12447 2002-09-28 Akim Demaille <akim@epita.fr>
12449 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12450 autoheader are Perl programs.
12451 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12452 (autom4te): Specify that the sources are in the $srcdir.
12453 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12455 2002-09-28 Akim Demaille <akim@epita.fr>
12457 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
12458 (tm_zone): Move their rules to...
12459 * lib/autoconf/types.m4: here, using AN_ macros.
12460 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12461 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12462 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
12463 * lib/autoconf/programs.m4: here.
12464 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
12465 (ETAGS_FOR_AUTOCONF): New.
12466 Use it.
12468 2002-09-28 Akim Demaille <akim@epita.fr>
12470 * lib/autoconf/autoscan.m4: New file.
12471 * lib/autoconf/autoconf.m4: Include it.
12472 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12473 that were listed in the original autoscan.list.
12474 * lib/autoconf/headers.m4: Similarly with headers.
12475 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12476 (.m4.m4f): Don't pass --prepend-include, since that's done by
12477 tests/autom4te itself.
12478 * lib/autoscan/Makefile.am: Include freeze.mk.
12479 (autoscan.list): New target --this file is no longer a source.
12480 (autoscan.pre): New file.
12482 2002-09-28 Akim Demaille <akim@epita.fr>
12484 * bin/autoscan.in (@kinds): Make them singular.
12485 Adjust all uses.
12486 (&init_tables): When --debug, report the list of rules to ease
12487 tracking changes in autoscan.list.
12488 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12490 2002-09-28 Akim Demaille <akim@epita.fr>
12492 * lib/autoscan/functions, lib/autoscan/headers,
12493 * lib/autoscan/identifiers, lib/autoscan/makevars,
12494 * lib/autoscan/programs: Merge into...
12495 * lib/autoscan/autoscan.list: this.
12496 * bin/autoscan.in (&init_tables): Adjust.
12498 2002-09-28 Akim Demaille <akim@epita.fr>
12500 * lib/autoscan/functions, lib/autoscan/headers,
12501 * lib/autoscan/identifiers, lib/autoscan/makevars,
12502 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12503 `functions' line is now prefixed with `function:'.
12504 * bin/autoscan.in (&init_tables): Adjust.
12506 2002-09-28 Akim Demaille <akim@epita.fr>
12508 From now on, autoscan files must always map a macro name to a
12509 word: there is no `default' macro for autoscan.
12511 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12512 all.
12513 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12514 explicit.
12516 2002-09-28 Akim Demaille <akim@epita.fr>
12518 * bin/autoscan.in (%c_keywords): Remove.
12519 (&used): Keep only track of the words we might be interested in.
12520 (&output_kind): It is no longer needed to look for non active
12521 checks.
12523 2002-09-27 Akim Demaille <akim@epita.fr>
12525 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12526 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12527 * lib/autoscan/functions: Adjust.
12528 * doc/autoconf.texi (Particular Functions): Adjust.
12530 2002-09-27 Akim Demaille <akim@epita.fr>
12532 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
12533 from /tmp.
12534 Thanks to Bill Moseley and Paul Eggert.
12535 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12536 the tmpdir must be created.
12537 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12538 dir be in the build tree, instead of $TMPDIR.
12540 2002-09-27 Akim Demaille <akim@epita.fr>
12542 * bin/autoscan.in: Improve the comments.
12543 (&parse_args): Drop obsolete undocumented options.
12544 (&output_kind): Output warnings.
12545 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
12546 (getwd): Trigger a warning.
12548 2002-09-26 Akim Demaille <akim@epita.fr>
12550 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12551 Reported by Ralf Corsepius.
12552 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12554 2002-09-26 Akim Demaille <akim@epita.fr>
12556 Single suffix rules and seperated dependencies are not portable.
12558 * doc/autoconf.texi (Installation Directory Variables): Update.
12559 (Limitations of Make): Some about `Single Suffix Rules and
12560 Separated Dependencies'.
12561 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12562 (ifnames, autoscan, autom4te): Un-factor into several rules.
12564 2002-09-25 Paul Eggert <eggert@twinsun.com>
12566 * BUGS (Interoperability bugs): New section. Mention libtool
12567 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12569 2002-09-24 Paul Eggert <eggert@twinsun.com>
12571 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12572 make handles suffix-rules differently from GNU make.
12574 * bin/Makefile.am (SUFFIXES, .in): Remove.
12575 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12576 Move the body of the old .in rule here.
12578 2002-09-16 Akim Demaille <akim@epita.fr>
12580 i960 compilers create `b.out' files by default.
12581 Reported by Ralf Corsepius.
12583 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12584 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12586 2002-09-13 Paul Eggert <eggert@twinsun.com>
12588 * doc/autoconf.texi (Particular Headers): Remove obsolete
12589 reference to `struct timezone' in the description of
12590 AC_HEADER_TIME.
12592 2002-09-13 Akim Demaille <akim@epita.fr>
12594 Version 2.54.
12596 * config/config.sub, config/config.guess: Update.
12597 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12598 * Makefile.am: Adjust.
12600 2002-09-13 Akim Demaille <akim@epita.fr>
12602 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12603 reading config.log when the compiler is rejected.
12604 Suggested by Guido Draheim.
12606 2002-09-13 Akim Demaille <akim@epita.fr>
12608 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12609 (chdir_init) might hang when stat'ing mounted directories.
12610 Reported by Vance Shipley.
12612 2002-09-12 Akim Demaille <akim@epita.fr>
12614 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12615 the lists.
12617 2002-09-12 Akim Demaille <akim@epita.fr>
12619 * doc/autoconf.texi (Defining Symbols): Present two different
12620 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12621 difference between 1 argument calls, and 2-3 argument calls.
12623 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12625 * doc/autoconf.texi: Review grammar and punctuation.
12627 2002-09-11 Paul Eggert <eggert@twinsun.com>
12629 * doc/autoconf.texi: Fix minor formatting, spelling, and
12630 grammatical typos.
12631 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12632 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12633 is obsolescent.
12635 2002-09-11 Akim Demaille <akim@epita.fr>
12637 * doc/autoconf.texi (Questions): Rename as...
12638 (FAQ): this.
12639 (Defining Directories): New.
12641 2002-09-09 Akim Demaille <akim@epita.fr>
12643 * doc/autoconf.texi (Making testsuite Scripts): Update.
12644 Suggested by Nishio Futoshi.
12646 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12648 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12649 plain `@' is wanted.
12651 2002-09-09 Akim Demaille <akim@epita.fr>
12653 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12654 `duplicates', since the algorithm was too naive and could keep
12655 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12656 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12657 Reported by Ralf Corsepius.
12658 * tests/torture.at (Configuring subdirectories): Exercise these
12659 cases.
12661 2002-09-09 Akim Demaille <akim@epita.fr>
12663 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12664 looking for a replacement file.
12665 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12666 directory is relative.
12667 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12668 directory definition.
12669 Reported by Andreas Schwab and Jim Meyering.
12671 2002-09-06 Akim Demaille <akim@epita.fr>
12673 * doc/autoconf.texi (Setting Output Variables): Clarify what
12674 precious variables are.
12675 Suggested by Pontus Skoeld.
12677 2002-09-05 Akim Demaille <akim@epita.fr>
12679 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12680 (ifnames, autoscan, autom4te): Since we don't only depend on
12681 configure.ac variables (such as VERSION etc.), but also on prefix
12682 and so forth, depend on Makefile, not configure.ac.
12683 Reported by Alexandre Duret-Lutz.
12684 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12686 2002-09-05 Kevin Ryde <user42@zip.com.au>
12688 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12689 doesn't seem to be confined to ia64, just say "some versions".
12691 2002-09-04 Akim Demaille <akim@epita.fr>
12693 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12694 Automake 1.6c.
12695 * Makefile.am (maintainer-clean-local): Remove.
12696 (MAINTAINERCLEANFILES): Remove COPYING.
12698 2002-09-03 Paul Eggert <eggert@twinsun.com>
12700 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12701 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12702 Brinkmann.
12704 2002-09-03 Akim Demaille <akim@epita.fr>
12706 * configure.ac: Bump to 2.53d.
12707 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12708 as of today, on Automake's team suggestion.
12710 2002-09-03 Akim Demaille <akim@epita.fr>
12712 Version 2.53c.
12714 2002-09-02 Akim Demaille <akim@epita.fr>
12716 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12717 SITE_MACRO_DIR.
12718 * configure.ac: Disable SITE_MACRO_DIR.
12720 2002-09-02 Jim Meyering <meyering@lucent.com>
12722 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12723 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12724 Also, tweak grammar: s/make sure to/be sure to/.
12726 2002-09-02 Paul Eggert <eggert@twinsun.com>
12728 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12729 directory names are generally preferable to physical names.
12731 2002-09-02 Akim Demaille <akim@epita.fr>
12733 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12734 Reported by Raja R. Harinath.
12735 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12736 * bin/autoupdate.in: Use error instead of die.
12738 2002-09-01 Paul Eggert <eggert@twinsun.com>
12740 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12741 ordinary shell concatenation rather than echo+tr+sed command that
12742 runs afoul of a long-line-related sed bug in Solaris 8.
12744 * bin/autoheader.in (parse_args): --warning -> --warnings.
12746 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12747 stdout, as traditional "ls" does.
12748 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12749 _AC_COMPILER_EXEEXT_O): Likewise.
12750 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12752 * bin/autoconf.as: Add --prepend-include option. This patch was
12753 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12754 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12756 * bin/autoconf.in, configure: Regenerate.
12758 * doc/autoconf.texi (Special Shell Variables): Mention
12759 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12761 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12762 MAILPATH and set PS1, PS2, PS4 to default values, to work
12763 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12764 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12765 the Autoconf documentation specifies; fall back to "unset" only if
12766 this fails. Use a shell for-loop for this rather than an m4 loop,
12767 to shorten the output script.
12769 2002-08-30 Paul Eggert <eggert@twinsun.com>
12771 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12772 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12773 for the CDPATH problem. Document PWD.
12774 (Limitations of Builtins): Document the problem that "cd $foo" and
12775 "ls $foo" may refer to different directories in shells conforming
12776 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12777 example, since the old example is now out of date.
12779 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12780 FOO" and "ls FOO" talk about different directories; this catches
12781 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12782 spaghetti.
12784 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12785 of rolling our own unset.
12786 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12787 in practice we needn't worry about CDPATH if unset doesn't work.
12789 * Makefile.in, aclocal.m4, bin/Makefile.in,
12790 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12791 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12792 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12793 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12794 tests/Makefile.in: Regenerate with Automake 1.6.3.
12796 * config/config.guess, config/config.sub, config/mkinstalldirs:
12797 Update.
12799 * configure: Regenerate with self.
12801 2002-08-30 Kevin Ryde <user42@zip.com.au>
12803 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12804 default output.
12806 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12808 * bin/autom4te.in (Request::load): Correctly test for "do" read
12809 failure.
12811 2002-08-29 Akim Demaille <akim@epita.fr>
12813 * lib/Autom4te/General.pm (&xqx): New.
12814 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12815 hand, which is not portable.
12816 (&error): New.
12817 * bin/autom4te.in: Use them.
12818 Use &error instead of die.
12819 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12820 Adjust.
12822 2002-08-17 Paul Eggert <eggert@twinsun.com>
12824 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12825 default list of compilers to try, since it was long ago superseded
12826 by the ksh fc builtin. Suggested by Steven G. Johnson.
12828 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12830 * doc/autoconf.texi (Invoking autom4te): End the option table,
12831 fixing a bug introduced by the previous patch.
12832 (Limitations of Make): Add a 'target lookup' subentry in the
12833 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12835 2002-07-29 Mark D. Roth <roth@feep.net>
12837 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12838 options and use $AUTOM4TE_PATH.
12839 * doc/autoconf.texi: Remove documentation of autom4te
12840 --include-envvar and --site-macro-subdir options and document
12841 use of $AUTOM4TE_PATH.
12842 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12843 arguments from each language section.
12845 2002-07-29 Paul Eggert <eggert@twinsun.com>
12847 * doc/install.texi: Include copyright symbol in copyright notice.
12849 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12850 Replace with:
12851 (AM_MAKEINFOFLAGS): New macro.
12852 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12853 * Makefile.am (INSTALL): Use the new macros.
12854 Use -o rather than --output, since "missing" does not grok --output.
12856 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12858 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12859 comments do not always work. Never trust the exit status of
12860 `make -k'.
12862 2002-07-24 Kevin Ryde <user42@zip.com.au>
12864 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12865 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12867 2002-07-23 Paul Eggert <eggert@twinsun.com>
12869 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12870 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12871 apparently treats PATH="nonexistent" as if it contained ".".

13010 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
13011 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
13012 so that we consistently test the just-built programs.
13013 * tests/wrappl.as: Likewise.

13033 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
13035 * bin/autom4te.in ($cache): Don't define using `$me', the name

13055 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
13056 AC_FUNC_FNMATCH_GNU.

13067 Suggested by Adam J. Richter.
13069 2002-06-07 Akim Demaille <akim@epita.fr>
13071 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
13072 ac_config_libobj_dir.
13073 (AC_CONFIG_LIBOBJ_DIR): New.
13074 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
13075 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
13076 Use ac_config_libobj_dir to find the replacement files.
13077 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

13082 * tests/mktests.sh (ac_exclude_list): Don't check

13096 Update from masters.
13098 2002-05-29 Paul Eggert <eggert@twinsun.com>

13121 * NEWS, doc/autoconf.texi (Particular Types): Document it.
13122 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
13123 instead of AC_MBSTATE_T, which never existed.
13125 2002-05-23 Akim Demaille <akim@epita.fr>
13127 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
13128 version of Autoconf that is discussed.
13130 2002-05-22 Paul Eggert <eggert@twinsun.com>
13132 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
13133 from the default list of compilers to try. Suggested by
13134 Kate Hedstrom.
13135 * NEWS: Document the above.
13136 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
13138 2002-05-17 Paul Eggert <eggert@twinsun.com>
13140 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
13141 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
13142 This improves on an earlier suggestion by H. Peter Anvin.
13144 2002-05-16 Paul Eggert <eggert@twinsun.com>
13146 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13147 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13148 Both macros now accept an optional source-dir arg.
13149 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13151 * NEWS: Document this.
13152 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13154 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13155 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13156 not for GNU extensions; this undoes part of the 2000-11-03 change,
13157 reverting to 2.13-compatible behavior.
13158 Add new optional argument DIR.
13159 (AC_FUNC_FNMATCH_GNU): New macro.
13161 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
13163 2002-05-08 Paul Eggert <eggert@twinsun.com>
13165 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13166 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13167 and it causes a 'test' syntax error if it fails.
13168 Bug reported by Stephen Gildea.
13170 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13171 If prototypes are supported, use them to check this at compile-time,
13172 instead of trying to check it at run-time. If we must do a run-time
13173 check, assume that setvbuf is standard when cross-compiling, as
13174 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13175 Bug reported by Paul D. Smith.
13177 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13178 argument specifying location of getloadavg.c. This removes a
13179 FIXME. This idea was taken from Jim Meyering's implementation in
13180 textutils.
13181 * doc/autoconf.texi (Particular Functions): Document this.
13182 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13183 that's what the code does; this fixes a bug reported by
13184 Paul D. Smith.
13186 2002-05-03 Akim Demaille <akim@epita.fr>
13188 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13189 autopoint instead of gettextize.
13190 ($uses_alocal): Rename as...
13191 ($uses_aclocal): this.
13192 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13193 Suggested by Bruno Haible.
13195 2002-05-03 Akim Demaille <akim@epita.fr>
13197 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13199 2002-04-29 Paul Eggert <eggert@twinsun.com>
13201 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13202 files to be 1 second older; just set them to be the same time.
13203 Also, sleep 1 second after the first aclocal, to work around
13204 problems with sub-second time stamps on the input files.
13206 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13208 * doc/autoconf.texi: Mention "set -e -x" lossage
13209 under node "Limitations of Builtins".
13211 2002-04-29 Akim Demaille <akim@epita.fr>
13213 * doc/install.texi: Better wording for setting variables when
13214 running configure.
13215 From Christian Cornelssen.
13217 2002-04-29 Akim Demaille <akim@epita.fr>
13219 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13220 of lack of $LINENO support, then the test will compare the $LINENO
13221 in testsuite vs. the lineno in the test file. This is wrong, of
13222 course.
13223 Be sure to protect it.
13224 Reported by Patrick Welche.
13226 2002-04-25 Akim Demaille <akim@epita.fr>
13228 * doc/autoconf.texi (Obsolete Macros): Typo.
13229 Reported by Vladimir Volovich.
13231 2002-04-25 Akim Demaille <akim@epita.fr>
13233 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13234 than some of the input files, hence, on the second run of aclocal,
13235 if some of its input are younger, make them older.
13236 Suggested by Paul Eggert.
13238 2002-04-25 Akim Demaille <akim@epita.fr>
13240 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
13241 Thanks to Paul Eggert.
13243 2002-04-25 Akim Demaille <akim@epita.fr>
13245 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
13246 and ac_subst_vars be sh variables containing the list of
13247 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13248 DEFAULT diversion.
13249 (_AC_INIT_PREPARE): Use them to log them.
13250 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13251 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13252 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13253 _AC_SUBST_FILES and _AC_SUBST_VARS.
13254 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13256 2002-04-24 Akim Demaille <akim@epita.fr>
13258 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13259 autoheader, so that automake does not complain about a missing
13260 config.h.in that was to be created.
13262 2002-04-23 Akim Demaille <akim@epita.fr>
13264 * bin/autoheader.in (parse_args): --warning takes an argument.
13265 Fixes PR/220.
13267 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
13269 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

13283 comma.
13284 Reported by Gregory Giannoni.
13286 2002-04-22 Akim Demaille <akim@epita.fr>
13288 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
13289 Fixes false failures on Darwin.

13316 * doc/autoconf.texi: Follow the outline suggested in the GNU
13317 Sample Texts sections of the Texinfo 4.2 manual. Most
13318 importantly, this makes sure that the copyright notices appear in
13319 all output formats. You probably need Texinfo 4.2 to generate
13320 the manual now.

13358 workaround for ${1+"$@"}.
13359 * doc/autoconf.texi (Shell Substitutions): Explain it.
13360 From Oliver Kiddle and Peter Stephenson.
13362 Have M4sh perform minimal shell sanitizing.
13364 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13365 part into...
13366 (_AS_PREPARE): this new macro.
13367 (AS_PREPARE): New.
13368 (AS_INIT): Invoke AS_SHELL_SANITIZE.
13369 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
13371 Adjust Autoconf and Autotest.
13373 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
13374 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
13375 * lib/autotest/general.m4 (AT_INIT): Likewise.
13376 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
13377 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
13378 AS_SHELL_SANITIZE.
13380 Use this M4sh to generate Autoconf's shell scripts.
13382 * tests/wrapsh.as: New, precursor of wrapsh.in.
13383 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13384 on Autotest and M4sh.
13385 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13386 (wrapsh.in): New target.
13387 * bin/autoconf.as: New, precursor of autoconf.in.
13388 (autoconf.in): New target.
13390 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
13392 * doc/autoconf.texi (Limitations of Make): Mention the issue
13393 with indented comments in rules.
13395 2002-04-09 Andreas Schwab <schwab@suse.de>
13397 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
13398 ac_top_builddir when setting ac_abs_top_builddir.
13400 2002-04-06 Kevin Ryde <user42@zip.com.au>
13402 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.

13408 directories when descending in a SUBDIRS.
13409 Reported by Ezra Peisach.
13411 2002-04-04 Andreas Schwab <schwab@suse.de>
13413 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13414 contains no literal separators.
13416 2002-04-03 Akim Demaille <akim@epita.fr>
13418 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13419 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13420 Use dnl, not the KILL diversion.
13421 Extracted from...
13422 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13423 (AC_CONFIG_LINKS): here.
13424 Adjust.
13425 Don't use the KILL diversion, as it kills spurious output, which
13426 results in failures being hidden.
13427 Use m4_defn where appropriate.
13428 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13429 after the second argument.
13430 Use m4_defn.
13431 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13432 syntax, as it is provided by M4sugar.
13433 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13435 2002-04-03 Andreas Schwab <schwab@suse.de>
13437 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

13450 Fixes Debian #138666.
13452 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13454 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13456 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13457 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13458 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13459 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13460 (AC_C_CONST): Same.

13472 2002-03-28 Kevin Ryde <user42@zip.com.au>
13474 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13475 to avoid versions of HP C which don't allow that.
13477 2002-03-27 Paul Eggert <eggert@twinsun.com>
13479 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13480 (AS_SHELL_SANITIZE): Invoke it.
13481 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
13483 2002-03-26 Akim Demaille <akim@epita.fr>
13485 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13487 2002-03-26 Akim Demaille <akim@epita.fr>
13489 * doc/autoconf.texi (Introduction): The GNATS base moved.
13491 2002-03-25 Paul Eggert <eggert@twinsun.com>
13493 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13494 as POSIX requires, as it doesn't work with Zsh.
13495 * doc/autoconf.texi (Assignments): Document the problem.
13497 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13499 * doc/autoconf.texi (Limitations of Make): Mention more issue
13500 about VPATH, overriding of macros in sub-makes, and handling of
13501 SHELL.
13503 2002-03-21 Paul Eggert <eggert@twinsun.com>
13505 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13506 problem with here-document buffer boundaries.
13508 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13509 when reinvoking the shell, to work around problems with installers
13510 who put strange things like "cd" commands in their environments.
13512 2002-03-19 Akim Demaille <akim@epita.fr>
13514 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13515 From Aaron Ucko.
13517 2002-03-19 Akim Demaille <akim@epita.fr>
13519 * bin/autoscan.in (scan_file): Specify the location in `&used'
13520 invocations.
13521 From Nicolas Joly.
13523 2002-03-19 Akim Demaille <akim@epita.fr>
13525 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13526 From Nishio Futoshi.
13528 2002-03-19 Akim Demaille <akim@epita.fr>
13530 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
13532 2002-03-18 Paul Eggert <eggert@twinsun.com>
13534 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13535 (Limitations of Usual Tools): Add mkdir section.
13537 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13538 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13539 back on AS_DIRNAME to compute prefixes otherwise; this is
13540 roughly what mkinstalldirs does. That way, we need not have
13541 our own filename disassembler. The old disassembler did not
13542 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13544 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13545 Create at_test_all by a series of assignments,
13546 not by a single assignment of a long string. The latter causes ksh
13547 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13548 presumably because of a buffer overrun.
13550 2002-03-14 Paul Eggert <eggert@twinsun.com>
13552 * lib/autotest/general.m4 (at_times_skip):
13553 Renamed from at_times. Now a boolean.
13554 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13555 says 'times: not found'.
13557 2002-03-14 Akim Demaille <akim@epita.fr>
13559 * bin/autoreconf.in (&study_gettextize): New.
13560 (&autoreconf): Handle newest gettextize.
13561 Rerun aclocal if needed.
13562 Suggested by Andreas Schwab.
13564 2002-03-13 Akim Demaille <akim@epita.fr>
13566 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13568 2002-03-13 Akim Demaille <akim@epita.fr>
13570 * doc/autoconf.texi (Header Portability): New.
13571 Add information about stdint.h and inttypes.h from Paul Eggert.
13573 2002-03-13 Akim Demaille <akim@epita.fr>
13575 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13576 -p'.
13577 From Bob Proulx.
13579 2002-03-12 Akim Demaille <akim@epita.fr>
13581 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13582 m4_require.
13584 2002-03-11 Andreas Schwab <schwab@suse.de>
13586 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13587 does not do it if --with-lispdir is given.
13589 2002-03-08 Akim Demaille <akim@epita.fr>
13591 Version 2.53.
13593 2002-03-08 Akim Demaille <akim@epita.fr>
13595 * doc/autoconf.texi (Subdirectories): Clarify that the
13596 subdirectory should exist.
13598 2002-03-08 Akim Demaille <akim@epita.fr>
13600 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13602 2002-03-08 Akim Demaille <akim@epita.fr>
13604 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13605 aliases the actual variables, and modifications of the former
13606 affect the latter.
13608 2002-03-08 Akim Demaille <akim@epita.fr>
13610 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13611 because of C-c: have m4 output in tmp files, then mv them.
13613 2002-03-08 Akim Demaille <akim@epita.fr>
13615 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13616 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13617 * bin/ifnames.in: Copyright update.
13619 2002-03-08 Akim Demaille <akim@epita.fr>
13621 * doc/autoconf.texi (Invoking autom4te): New.
13623 2002-03-05 Akim Demaille <akim@epita.fr>

13626 Kevin Ryde.
13628 2002-03-05 Akim Demaille <akim@epita.fr>
13630 Version 2.52i.
13632 2002-03-04 Akim Demaille <akim@epita.fr>
13634 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13635 * lib/autoconf/general.m4 (AC_INIT): More informative error
13636 message for LIBOBJ.
13638 2002-03-04 Akim Demaille <akim@epita.fr>
13640 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13641 parallel builds.
13643 2002-03-04 Akim Demaille <akim@epita.fr>
13645 * doc/autoconf.texi (Transforming Names): Equality between target
13646 and host is irrelevant.
13647 (Specifying Names, Canonicalizing): Remove all references to the
13648 backward compatibility hooks. Rather, collect them all into...
13649 (Hosts and Cross-Compilation): this new section.
13650 * doc/install.texi (System Type): Ditto.
13651 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13652 that `--host' implies cross-compilation.
13654 2002-03-04 Akim Demaille <akim@epita.fr>
13656 * doc/autoconf.texi (Evaluation Macros): New.
13657 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13658 useless.
13659 (_m4_foreach): Define the variant with immediate evaluation so
13660 that it contains exactly the items, not an expression which
13661 evaluation is the current item.
13662 (m4_re_string, m4_re_word): Don't over quote them.
13664 2002-03-04 Akim Demaille <akim@epita.fr>
13666 Instead of having stacking `shift's evaluated at the end, let
13667 `foreach' loops immediately evaluate them.
13669 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13670 $*. This is the n-th time I change my mind, but hopefully this is
13671 the last...
13672 (m4_lquote): New.
13673 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13674 efficient.
13675 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13676 it was only a hack for m4_text_wrap.
13677 (m4_car2): Remove, replaced by...
13678 (m4_cdr): New.
13679 (_m4_foreach): Adjust.
13680 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13681 m4_bpatsubst for clarification.

13725 Fix Autoconf PR/209.
13726 Also reported by Frank Denis.
13728 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13730 2002-02-07 Akim Demaille <akim@epita.fr>

13733 AC_PREFIX_PROGRAM fails with dashed program names
13735 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

13774 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13796 * bin/autom4te.in (&parse_args): Implement `frozen files are
13797 optional are the sum of the previous files on the command line'.
13798 Also, pass `--reload-state=' on them, so...
13799 (handle_m4): don't.
13800 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13801 (M4sh): Rely on M4sugar.
13802 (Autotest, M4sh, M4sugar): Use frozen files.
13804 2002-01-31 Akim Demaille <akim@epita.fr>
13806 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13807 * doc/autoconf.texi (Initializing configure): Adjust.
13809 2002-01-30 Akim Demaille <akim@epita.fr>
13811 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13812 alphanumeric to `-' instead of `_'.
13814 2002-01-30 Akim Demaille <akim@epita.fr>
13816 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13817 for plain code, the other for cross-compilation code. The latter
13818 is now run with GCC only.
13819 * doc/autoconf.texi (Compilers and Preprocessors): New.

13830 * tests/torture.at (Configuring subdirectories): Use configure.in,
13831 so that aclocal 1.4 works.
13832 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13834 2002-01-28 Akim Demaille <akim@epita.fr>
13836 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13837 needs an argument.
13839 2002-01-28 Akim Demaille <akim@epita.fr>
13841 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13842 AUTOTEST_PATH *after* it was set.
13843 Don't put `.' in the PATH: the user should be precise and `./' if
13844 needed. In addition, given that the test suite does some `cd', if
13845 `.' is in the path, the `tested programs' sections will report
13846 programs found in the test suite's directory, while during the
13847 tests (performed in their own directory), these programs are no
13848 longer visible. In other words, the results is confusing and
13849 useless.
13850 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13852 2002-01-24 Akim Demaille <akim@epita.fr>
13854 Version 2.52g.

13859 * doc/autoconf.texi: Finally add Akim as an author.
13861 2002-01-24 Akim Demaille <akim@epita.fr>
13863 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13864 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13865 Bourne. Use /bin/sh.
13866 From Andreas Buening.
13868 2002-01-24 Akim Demaille <akim@epita.fr>
13870 * config/config.guess, config/config.sub, config/texinfo.tex:

13880 Automake.
13882 2002-01-24 Akim Demaille <akim@epita.fr>
13884 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13885 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13886 Reported by Geir Ove Myhr.
13888 2002-01-21 Akim Demaille <akim@epita.fr>
13890 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13892 2002-01-21 Akim Demaille <akim@epita.fr>
13894 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13895 message on invalid options.
13896 * bin/autom4te.in (parse_args): Don't use
13897 Autoconf::General::getopt with non valid options.
13899 2002-01-17 Jim Meyering <meyering@lucent.com>
13901 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13902 $ac_cv_exeext so we don't use an old, invalid, cached value.
13904 2002-01-11 Akim Demaille <akim@epita.fr>
13906 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

13915 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13916 package.m4, since is really depends upon configure.ac, not
13917 configure.
13918 * doc/autoconf.texi (testsuite Scripts): Adjust.
13919 * tests/Makefile.am (package.m4): New.
13920 EXTRA_DIST it since its a source.
13922 2002-01-06 Akim Demaille <akim@epita.fr>
13924 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13925 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13926 and PACKAGE_BUGREPORT from here...
13927 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13928 arguments.
13929 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13930 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13931 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13932 * tests/tools.at (autoheader): Adjust.
13933 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

13947 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13948 sometimes needing writable input.
13950 2001-12-17 Jim Meyering <meyering@lucent.com>
13952 * doc/autoconf.texi (New Macros): Tweak wording.
13954 2001-12-14 Akim Demaille <akim@epita.fr>
13956 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13957 trailing files, don't apply `-rf' to files which might not be
13958 created by configure (core, core.*, and *.core), but just `rm -f'.
13959 Suggested by Jonathan Kamens.
13961 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13963 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13965 2001-12-14 Akim Demaille <akim@epita.fr>
13967 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13969 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13971 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13972 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13973 abs_srcdir, top_srcpath to abs_top_srcdir.
13974 (_AC_OUTPUT_FILES): Adjust.
13975 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13976 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13977 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13979 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13981 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13982 C/Fortran linking on HP/UX, by extracting the Fortran library
13983 search path from the LPATH line in the $F77 -v output.
13985 2001-12-12 Kevin Ryde <user42@zip.com.au>
13987 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13988 forbidden file descriptors table.
13990 2001-11-26 Akim Demaille <akim@epita.fr>
13992 * bin/autoscan.in (%c_keywords): Build it at top level.
13993 Map to 1 in order to simplify its uses.
13995 2001-11-26 Akim Demaille <akim@epita.fr>
13997 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13998 Remove $filepath, useless.
13999 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
14000 variables, they are really part of the tokens.
14001 Split the input line on spaces and then look for tokens.
14002 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
14003 because of `lex$U.$(OBJEXT)'.
14004 (&scan_files): Use "@list" instead of join.
14005 * doc/Makefile.am (CLEANFILES): Add *.fns.
14007 2001-11-26 Akim Demaille <akim@epita.fr>
14009 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
14010 Remove, replaced by...
14011 * tests/wrappl.in: Be common for all the Perl executables.
14012 In particular autoscan and autoheader want -I.
14013 * configure.ac: Adjust.
14014 * lib/autoscan/headers: errno.h is portable.
14016 2001-11-26 Akim Demaille <akim@epita.fr>
14018 * bin/autoscan.in (used): New.
14019 Use it.

14025 (&scan_sh_file): Remove a duplicate pattern.
14026 (&check_configure_ac): Use long options.
14027 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
14029 2001-11-26 Akim Demaille <akim@epita.fr>
14031 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
14032 Before, having a line containing the opening of a multi line
14033 comment made the whole line be ignored.
14035 2001-11-26 Akim Demaille <akim@epita.fr>
14037 * doc/autoconf.texi (Using an Autotest Test Suite): New.
14038 (testsuite Scripts): Be one of its subsection.
14039 (Autotest Logs): New.
14041 2001-11-26 Akim Demaille <akim@epita.fr>
14043 Test groups are now run two directories deeper.
14045 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
14046 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
14047 at_top_builddir.
14048 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
14049 top_srcdir, builddir and top_builddir.
14050 Use `at_*dir' relatively to the directory containing the
14051 suite, use `*dir' when relatively to the current group dir.
14053 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14055 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14056 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14057 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14058 spelling errors.
14060 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14062 * doc/autoconf.texi (Using System Type): Add an example of `case
14063 $host' usage so people quit using `case $target' everywhere.
14065 2001-11-22 Akim Demaille <akim@epita.fr>
14067 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14068 spotted by Jim Meyering.
14070 2001-11-16 Paul Eggert <eggert@twinsun.com>
14072 This patch implements a `long double' suggestion by Oliver Kiddle.
14074 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14075 static, to catch errors if the value isn't known at compile-time
14076 and the compiler supports dynamic arrays. Change its name from
14077 `_array_' to `test_array' to avoid potential name clashes.
14078 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14079 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14080 better than double. Catch a bug in GCC 2.95.2 x86.
14081 * doc/autoconf.texi (C Compiler): Document the above.
14082 * NEWS: Likewise.
14084 2001-11-13 Akim Demaille <akim@epita.fr>
14086 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14087 hand.
14088 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14090 2001-11-13 Akim Demaille <akim@epita.fr>
14092 * lib/autotest/general.m4 (AT_INIT): After having run the test
14093 group, go back to the initial directory, not to at_suite_dir.
14095 2001-11-13 Akim Demaille <akim@epita.fr>
14097 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14098 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14099 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14100 option.
14101 (AT_CHECK_CONFIGURE): Use absolute paths.
14102 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14103 The problem is still the old one: there is no means in M4 (that I
14104 know about) to create a defining macro, because there is no means
14105 to create `$1' etc., therefore, the defining macro ``swallows''
14106 all the arguments meant to the defined macro.
14108 2001-11-13 Akim Demaille <akim@epita.fr>
14110 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14111 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14112 configure.ac.
14113 * tests/aclocal.m4: Remove, as it is no longer used.
14115 2001-11-13 Akim Demaille <akim@epita.fr>
14117 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14118 variable names when referring to a single test group, or to
14119 `suite' when referring to the whole test suite.
14120 `at_last_test' is removed: m4 compute at_format itself.
14121 (at_stdout, at_stder1, at_stderr): New variables.
14122 (AT_CHECK): Use them.
14124 2001-11-13 Akim Demaille <akim@epita.fr>
14126 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14127 in PATH.
14128 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14129 Do it as soon as a test fails, don't wait till the end of the test
14130 suite.
14131 Don't remove $as_me.[0-9]*, since these files no longer exist.
14133 2001-11-13 Akim Demaille <akim@epita.fr>
14135 * tests/tools.at: Use absolute paths, since we are no longer run
14136 in place.
14138 2001-11-13 Akim Demaille <akim@epita.fr>
14140 Now that tests are running in their own private dir, there is no
14141 need to list the files to remove at the end of tests groups.
14143 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14144 (AT_data_files, at_data_files): Remove.
14145 (AT_CLEANUP, AT_DATA): Simplify.
14146 (AT_INIT): Adjust.
14147 Remove the group dir if !debug && !failed.
14148 * tests/atspecific.m4: Adjust.
14150 2001-11-13 Akim Demaille <akim@epita.fr>
14152 Start a new layout for Autotest: `testsuite' creates
14153 `testsuite.dir' in which the at-check-line etc. files are to be
14154 found, and `testsuite.dir/003' where the test group 3 is run.
14156 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14157 at_check_line_file, at_format, at_test_normalized, at_group_dir
14158 are new variables.
14159 Create the directories.
14160 Use absolute paths for at- files.
14161 (AT_CHECK): Adjust.
14163 2001-11-11 Michael Matz <matz@kde.org>
14165 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14166 (m4_car2): New.
14167 (m4_car): Properly quote arguments.
14169 2001-11-13 Akim Demaille <akim@epita.fr>
14171 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14172 with stricter rules on LIBOBJS.
14174 2001-11-12 Paul Eggert <eggert@twinsun.com>
14176 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14177 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14178 __PROTOTYPES too.
14180 2001-11-12 Akim Demaille <akim@epita.fr>
14182 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14184 2001-11-12 Akim Demaille <akim@epita.fr>
14186 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14187 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14188 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14189 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14190 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14191 specify to what the macro should be defined (typically to 1).
14193 2001-11-12 Akim Demaille <akim@epita.fr>
14195 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14196 From Jim Meyering.
14198 2001-11-12 Akim Demaille <akim@epita.fr>
14200 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14201 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14202 definition used by Automake where LEX is +/- "${missing} lex" and
14203 `missing' itself contains variables.
14205 2001-11-12 Akim Demaille <akim@epita.fr>
14207 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14208 Now that M4sh pushes BODY, the comments were output at the end of
14209 the test suites.
14211 2001-11-08 Akim Demaille <akim@epita.fr>
14213 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14214 that we can trace macros from aclocal.m4.
14215 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14216 obsoleted, and redirect to the former anyway.
14217 Reported by Ralf Corsepius.
14219 2001-11-08 Akim Demaille <akim@epita.fr>
14221 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14222 processed only if present.
14223 * tests/torture.at (Configuring subdirectories): Use autoreconf
14224 instead of successive calls to autoconf.
14225 Add a nonexistent subdirectory to exercise the patch above.
14226 Reported by Ralf Corsepius.
14228 2001-11-08 Kevin Ryde <user42@zip.com.au>
14230 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14231 doesn't accept .S files.
14233 2001-11-07 Akim Demaille <akim@epita.fr>
14235 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

14237 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14238 * bin/autom4te.in (warn_forbidden): New.
14239 (handle_output): Use it.
14240 Read m4_pattern_forbid with messages.
14242 2001-11-05 Akim Demaille <akim@epita.fr>
14244 * bin/autom4te.in (--normalize): Remove.
14245 * lib/autom4te.in: Adjust.
14247 2001-11-05 Akim Demaille <akim@epita.fr>
14249 * tests/Makefile.am (testsuite): Rename this target as...
14250 ($(TESTSUITE)): this.
14251 From Nicolas Joly.
14253 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14255 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14256 the --prefix option, also remove it's argument.
14258 2001-11-05 Akim Demaille <akim@epita.fr>
14260 * doc/autoconf.texi (testsuite Invocation): Update.
14261 (Writing testsuite.at): Update.
14263 2001-11-03 Akim Demaille <akim@epita.fr>
14265 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14267 2001-11-03 Akim Demaille <akim@epita.fr>
14269 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14270 (&file_name_is_absolute): New, wrappers around routines from
14271 File::Spec.
14272 Use and export them.
14273 (&find_configure_ac): Optionally take a directory where to look at.
14274 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14275 the arguments.
14276 Default @ARGV to `.', not find_configure_ac.
14277 (&autoreconf): Argument is a directory.
14278 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14279 * doc/autoconf.texi (autoreconf Invocation): Update.
14281 2001-11-03 Akim Demaille <akim@epita.fr>
14283 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14284 (@export_forward_subs): New.
14285 Add basename, dirname, and fileparse.
14286 (@EXPORT): Adjust.
14287 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14288 Don't look for aclocal flags if we already know aclocal is not
14289 used.
14290 Move aclocal.m4t only if it exists.
14291 Reported by Ezra Peisach.
14293 2001-11-03 Akim Demaille <akim@epita.fr>
14295 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14296 passed on command line, defaulting to ./configure.ac if present.
14297 (&maybe_autoreconf, File::Find): Remove, unused.
14298 (&autoreconf): If autoconf is not used, don't try to trace.
14300 2001-11-02 Akim Demaille <akim@epita.fr>
14302 * configure.ac: Bump to 2.52g.
14304 2001-11-02 Akim Demaille <akim@epita.fr>
14306 Version 2.52f.
14308 2001-11-02 Akim Demaille <akim@epita.fr>
14310 * config/config.guess, config/config.sub, doc/standards.texi:
14311 * config/lispdir.m4: Update from masters.
14312 * configure.ac: Bump to 2.52f.
14314 2001-11-02 Akim Demaille <akim@epita.fr>
14316 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14317 Don't run aclocal when aclocal.m4 is not from aclocal.
14318 From Ezra Peisach.
14319 Don't run libtoolize and gettextize if --install is not given.
14321 2001-11-01 Paul Eggert <eggert@twinsun.com>
14323 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14324 be invoked before _AS_LINENO_PREPARE.
14325 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14326 than character ranges.
14328 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14329 invoking AS_BASENAME. Set the locale variables to 'C' if
14330 possible, as POSIX requires this to get the traditional
14331 behavior.
14332 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14334 2001-10-31 Paul Eggert <eggert@twinsun.com>
14336 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14337 with {}, as that triggers a bug in Bash 2.05.
14339 (_AS_LINENO_PREPARE): Use Sed rather than
14340 Awk. Fix the sed prepass to work even if there are multiple
14341 instances of $LINENO on the same line. Do not substitute for
14342 other variables like $LINENOT. Do not check file dates; such a
14343 check is unreliable on sufficiently fast machines, and removing
14344 the check makes the code simpler and more reliable. Check for
14345 output and chmod failures.
14347 * doc/autoconf.texi (Special Shell Variables): Document
14348 the above.
14350 2001-10-31 Akim Demaille <akim@epita.fr>
14352 * tests/Makefile.am (atconfig): Remove this target, Automake
14353 handles it now.
14355 2001-10-31 Akim Demaille <akim@epita.fr>
14357 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14358 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14359 provided, while it is optional.
14360 * configure.ac: Adjust.
14362 2001-10-26 Paul Eggert <eggert@twinsun.com>
14364 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14365 lib/Autom4te/Struct.pm:
14366 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14367 with 5.005_02.
14369 * doc/autoconf.texi (Special Shell Variables): Document some
14370 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14372 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14373 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14374 eval $LINENO is not portable in practice.
14376 2001-10-24 Akim Demaille <akim@epita.fr>
14378 * lib/Autom4te/General.pm (backname): New.
14380 2001-10-24 Akim Demaille <akim@epita.fr>
14382 * m4/: Remove, merged into...
14383 * config/: here.
14385 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14387 * doc/autoconf.texi (Shellology): Mention the problems with bash
14388 2.05's use of ANSI quoting in its `set' builtin.
14390 2001-10-22 Paul Eggert <eggert@twinsun.com>
14392 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14393 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14394 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14395 POSIX decided to standardize on the int flavor of strerror_r.
14396 Always do char* test, as there's no reason not to.
14397 Assign to a char* var, to catch strerror_r that returns int*.
14399 * doc/autoconf.texi (Particular Functions):
14400 Document the above changes. Also, document the fact that
14401 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14403 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14405 2001-10-20 Akim Demaille <akim@epita.fr>
14407 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14408 the executable was missing from the log.

14412 * lib/Autom4te/General.pm (&update_file): If destination is
14413 unchanged, remove the source.
14414 (&up_to_date_p): Don't be verbose, be debug.
14415 * bin/autoreconf.in: No longer support --m4dir.
14416 (&autoreconf): Display the full path of the configure.ac we are
14417 studying.
14418 Trace it only once.
14419 Be sure to honor --force with gettextize.
14420 Always run aclocal.
14421 * doc/autoconf.texi: Adjust.
14423 2001-10-20 Akim Demaille <akim@epita.fr>
14425 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14426 Remove, dead.
14427 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14428 `intl' is already present, as it refuses unless --force.
14429 (&parse_args): Use -I, --include instead of the old Autoconf
14430 options.
14431 ($localdir, $autoconf_dir): Remove.
14432 (@include): New.
14433 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14435 2001-10-19 Jens Petersen <petersen@redhat.com>
14437 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

14442 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
14443 file in @configure_input@.
14444 Don't mention `automatically' in addition to `generated'.
14445 * tests/torture.at (#define header templates): Adjust.
14447 2001-10-19 Akim Demaille <akim@epita.fr>
14449 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
14450 comment, explain how to install automatic mode selection.
14451 From Russ Allbery.
14453 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14455 * bin/autoreconf.in (autoreconf): Display the path to the
14456 configure.ac being studied.
14458 2001-10-18 Paul Eggert <eggert@twinsun.com>
14460 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14461 long, to work around a bug in the HP C compiler version HP92453-01
14462 B.11.11.23709.GP.
14464 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14465 (AS_BASENAME_EXPR): New macro.
14466 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14467 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14468 and fall back on 'sed' only if the other two fail. This makes
14469 AS_BASENAME act more like AS_DIRNAME.
14470 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14471 contains white space.
14472 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14473 Use AS_DIRNAME, since I think it's now DOS-friendly.
14474 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14475 Allow "dirname //FOO" to return either / or //, as POSIX allows
14476 either behavior.
14478 2001-10-10 Akim Demaille <akim@epita.fr>
14480 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
14481 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
14482 From Eric Sharkey.
14484 2001-10-10 Akim Demaille <akim@epita.fr>
14486 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14487 m4_define, since...
14488 (_AS_ECHO_N): AS_REQUIREs it.
14490 2001-10-10 Akim Demaille <akim@epita.fr>

14526 bother with $force since...
14527 * lib/Autom4te/General.pm: does.
14529 2001-10-08 Akim Demaille <akim@epita.fr>
14531 * bin/autoreconf.in: Rewrite in Perl.
14532 * configure.ac: Adjust.

14583 Use `add-log-current-defun-function' for ChangeLog creation.

14605 * tests/tools.at (AT_DATA_FORBIDDEN): New.

14616 empty, and if we can find a shell that does support LINENO,
14617 then set CONFIG_SHELL to that shell and then re-execute
14618 ourselves with CONFIG_SHELL.
14620 2001-10-05 Paul Eggert <eggert@twinsun.com>
14622 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
14623 doesn't exist. Remove *.tmp, as a .tmp file is created during the
14624 build of $(TESTSUITE).
14626 2001-10-05 Akim Demaille <akim@epita.fr>
14628 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

14670 instead of exec'ing to preserve $0 and $@.
14672 2001-10-01 Akim Demaille <akim@epita.fr>
14674 * tests/testsuite (AT_INIT) <at_pass_list>: New.

14693 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
14694 Don't use nested parenthesization. This patch was originally
14695 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
14696 but somehow it didn't get incorporated then.
14697 * doc/autoconf.texi (Limitations of Usual Tools):
14698 Clarify remark about sed and nested parenthesization.
14700 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
14701 Report an error if the size cannot be determined even though
14702 the type exists.
14703 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14704 Check for `expr' arithmetic overflow, and for compilation failure,
14705 and invoke a new argument $4 if either is discovered.
14706 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14707 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
14709 2001-09-28 Akim Demaille <akim@epita.fr>

14723 2001-09-27 Akim Demaille <akim@epita.fr>
14725 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that

14729 status when executing the ACTION-IF-FALSE.

14737 * tests/c.at (Extensions, C keywords)
14738 (Broken/missing compilers, AC_PROG_CPP with warnings)
14739 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
14740 (AC_PROG_CPP requires AC_PROG_CC): here and...
14741 * tests/fortran.at (GNU Fortran 77): there.
14742 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14743 AC_TRY_RUN is about compilation, not shell commands.

14748 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
14749 Raja R Harinath:
14750 Be sure to detect when $LINENO always returns the same value.
14751 Look for the original script, basename($0) is certainly not
14752 enough.

14848 * tests/Makefile.am (package.m4): Remove.
14850 2001-09-22 Akim Demaille <akim@epita.fr>
14852 Rely on `$LINENO' when possible instead of `__oline__'.
14854 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14855 `$LINENO' support replacement when not supported.
14856 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14857 them explicitly to be sure they are not output before this section
14858 (via m4_require). Cosmetic only.
14859 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14860 * lib/autoconf/programs.m4: Replace all the occurrences of

14866 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14867 character (u: -> ue) in a code comment.
14868 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14869 it works.
14871 2001-09-21 Akim Demaille <akim@epita.fr>
14873 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14874 Suggested by Jim Meyering.
14876 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14878 * lib/autoconf/programs.m4: Use extensions listed in
14879 $ac_executable_extensions when looking for programs.

14883 * lib/autoconf/general.m4: Fix a small Englisho.

14891 PATH_SEPARATOR.
14892 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

14895 * lib/autotest/general.m4: Replace occurrences of ':' in
14896 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14898 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14900 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14901 arguments. Fixed a typo.
14903 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14905 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
14906 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
14908 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14910 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14911 * bin/autoupdate.in: Ditto.
14912 * bin/autoheader.in: Reworded a few comments.
14913 * bin/autoconf.in: Reworded help text for a few options.

14917 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14919 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14920 already have $file). Set output files to binary mode (helps avoid
14921 CR issues on DOSish systems).
14923 2001-09-19 Akim Demaille <akim@epita.fr>
14925 * lib/autotest/general.m4: Englishoes.
14926 From Tim Van Holder and Alexey Mahotkin.
14928 2001-09-18 Paul Eggert <eggert@twinsun.com>
14930 * doc/autoconf.texi (Common Shell Constructs): New node,
14931 documenting AS_DIRNAME.
14932 (Limitations of Usual Tools): Refer to it when discussing dirname.
14933 Also, update discussion of POSIX standard to reflect latest draft.
14935 * lib/autoconf/c.m4:
14936 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14938 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14939 Do not pass a first argument with leading '-'
14940 to expr, by parenthesizing initial integers that might be negative.
14942 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14943 now merely checks whether it is an error to pass an argument
14944 to getpgrp.
14946 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14947 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14948 whether it is a (compile-time) error to pass an argument to
14949 getpgrp. This simpler test supports the revised documentation,
14950 and is all that AC_FUNC_GETPGRP's users really need.
14952 2001-09-18 Akim Demaille <akim@epita.fr>
14954 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14956 2001-09-18 Akim Demaille <akim@epita.fr>

14964 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14965 correctly.
14966 Add test for AS_BASENAME.
14967 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14968 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14969 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14970 * tests/base.at: Fixed the expected responses. The old ones were
14971 one line out...
14972 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14973 the documentation claims it should (and how it behaved in 2.13).
14975 2001-09-18 Akim Demaille <akim@epita.fr>
14977 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14978 the AC_CONFIG_COMMANDS invocation.
14979 This also solves the name clash problems.
14980 Don't set the package's ID.
14981 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14982 No longer to be shipped.
14983 (version.in): Remove.
14984 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14985 * lib/autoconf/status.m4: Adjust.
14986 Use `m4_PACKAGE_STRING'.
14987 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14988 the only optional argument is the name of the test suite.
14989 Expect `package.m4' to define the package signature.
14990 * lib/autom4te.in (Autotest): Add `package.m4?'.
14991 * tests/Makefile.am (package.m4): New.
14992 * tests/suite.at: ifnames is a victim.
14994 2001-09-18 Akim Demaille <akim@epita.fr>
14996 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14997 AC_LIBSOURCE, AC_CONFIG_FILES.
14998 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14999 program version string doesn't match the package's.
15000 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
15001 after `(cached)'.

15005 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15006 Allow expression to return any value that can fit into unsigned long
15007 (not int, as before). Check for output errors.
15009 2001-09-17 Bruno Haible <haible@ilog.fr>
15011 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15012 Always include <stdio.h> and <stdlib.h>. Evaluate
15013 the expression in an extra function before these includes. Call
15014 fprintf "%d" only after ensuring the argument is of type 'int'.
15015 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
15017 2001-09-17 Paul Eggert <eggert@twinsun.com>
15019 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
15020 or CFLAGS=-O5. In that case, the linker has a relaxed view of
15021 fatal errors, and AC_CHECK_LIB causes it to include libraries even
15022 when they don't exist.
15024 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
15025 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
15026 need it.
15028 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
15029 version with the version used by fileutils 4.1, except use
15030 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
15031 we don't need it.
15033 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
15035 2001-09-13 Akim Demaille <akim@epita.fr>
15037 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
15038 _first_.
15039 Reported by Gerrit P. Haase.
15041 2001-09-13 Akim Demaille <akim@epita.fr>
15043 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
15044 m4_defn'ing is valid.

15059 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
15060 Likewise.

15063 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
15064 AT_tests_all for consistency.

15066 (AT_VICTIMS): Similar to AT_KEYWORDS.
15067 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
15069 2001-09-13 Akim Demaille <akim@epita.fr>
15071 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
15073 2001-09-13 Akim Demaille <akim@epita.fr>
15075 * lib/autotest/general.m4 (AT_INIT): Create and remove
15076 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15077 test suites can cohabit.
15079 2001-09-13 Akim Demaille <akim@epita.fr>
15081 * tests/mktests.sh: Don't output banners for empty test files.
15083 2001-09-13 Akim Demaille <akim@epita.fr>
15085 Test suites can be run independently of configure.

15100 (Syntax of the shell scripts): Don't check ifnames.
15101 (AT_CHECK_PERL_SYNTAX): New.
15102 (Syntax of the Perl scripts): Check ifnames.
15103 * tests/ifnames: New.

15131 2001-09-10 Akim Demaille <akim@epita.fr>
15133 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

15149 2001-09-07 Akim Demaille <akim@epita.fr>
15151 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
15152 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
15153 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
15154 related variables into `at_package_*'.

15164 Move toward possibly stand-alone test suites.
15166 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
15167 in addition, it introduces useless differences in logs.
15168 (AT_INIT): Let atconfig and atlocal be both optional.
15169 Adjust PATH computation.
15170 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

15174 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

15177 2001-09-05 Akim Demaille <akim@epita.fr>
15179 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
15180 to avoid GCC warnings.
15181 From Uwe Seimet.
15183 2001-09-05 Akim Demaille <akim@epita.fr>
15185 * bin/autom4te.in: --language is -l, not -s.
15187 2001-09-05 Akim Demaille <akim@epita.fr>
15189 Be ready to handle filenames as stupid as `dnl.at', for if even
15190 the maintainer is dumb enough to do that...
15192 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15193 excellence in M4 quotation: consider `__file__' is active.
15195 And BTW, when invoking m4, pass the --include in the right order:
15196 the wrong one.
15198 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
15199 4m.
15201 2001-09-05 Akim Demaille <akim@epita.fr>
15203 * lib/Autom4te/XFile.pm: New lib file.
15204 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
15205 * bin/autoheader.in: Use it.
15207 2001-09-05 Akim Demaille <akim@epita.fr>
15209 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
15210 defined.

15215 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust.
15217 * bin/autoscan.in: Use `getopt' and `find_files' etc.
15218 Add -I, --include support.
15219 * doc/autoconf.texi (autoscan Invocation): Adjust.
15221 2001-09-05 Akim Demaille <akim@epita.fr>
15223 CVS GNU M4 doesn't like `undefine(undefined)'.
15225 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
15226 New, extracted from main.
15227 Use IO::File wherever possible.
15228 (input.m4): Be constant, use -I instead of hard coding $tmp.
15229 Therefore be a quoted heredoc.
15230 Don't invoke `_au_disable', since ac was not loaded, but just
15231 `unm4.m4'.
15233 2001-08-31 Akim Demaille <akim@epita.fr>
15235 Version 2.52d.
15237 2001-08-31 Akim Demaille <akim@epita.fr>
15239 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
15240 previous patch.
15241 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
15243 2001-08-31 Akim Demaille <akim@epita.fr>
15245 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
15246 serious problems handling heredocs in heredocs.
15247 Reported by Nicolas Joly.
15249 2001-08-31 Akim Demaille <akim@epita.fr>
15251 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
15252 (Making testsuite Scripts): Update.
15254 2001-08-31 Akim Demaille <akim@epita.fr>
15256 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
15258 2001-08-31 Akim Demaille <akim@epita.fr>
15260 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
15261 (testsuite Scripts): There is no such thing as `atconfig.in'.
15262 And actually one diagram is missing: test suite runtime.
15264 2001-08-31 Akim Demaille <akim@epita.fr>
15266 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
15267 inverse order.
15269 2001-08-31 Akim Demaille <akim@epita.fr>
15271 * bin/autoupdate.in (@include): `installcheck' revealed the path
15272 to m4sugar was lacking!
15274 2001-08-31 Akim Demaille <akim@epita.fr>
15276 * man/Makefile.am (.x.1): We really have to pass
15277 autom4te_perllibdir.
15279 2001-08-31 Akim Demaille <akim@epita.fr>
15281 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
15282 debug scripts, in particular passing explicitly listed tests to
15283 run is stupid.
15285 2001-08-31 Akim Demaille <akim@epita.fr>
15287 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
15288 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
15289 Use directly autom4te, not autoconf.
15290 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
15292 2001-08-31 Akim Demaille <akim@epita.fr>
15294 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
15295 * bin/autoheader.in (%symbol): Strip arguments of macros.

15301 2001-08-31 Akim Demaille <akim@epita.fr>
15303 * bin/autom4te.in (&parse_args): Die on unknown languages.
15304 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
15305 need for autoconf.
15306 Promote --include over --macrodir and other obsolete options.
15308 2001-08-31 Akim Demaille <akim@epita.fr>
15310 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
15311 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
15312 * bin/autom4te.in ($autoconf): Pass --force.
15313 `print $out' doesn't print `$_' but `$out'.
15314 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
15315 (autoheader): Pass --force since the test suite goes too fast for
15316 the time stamps.
15317 Adjust to the new autoheader messages.
15319 2001-08-31 Akim Demaille <akim@epita.fr>
15321 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
15322 Check the completeness of the #template.
15323 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
15324 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
15325 invocation.
15327 2001-08-31 Akim Demaille <akim@epita.fr>
15329 * lib/Autom4te/General.pm (&find_file, &update_file): New.
15330 * bin/autoupdate.in, bin/autoheader.in: Adjust.
15331 Drop AC_MACRODIR dead for real.
15332 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15333 `autoheader: `config.hin' is created'.
15334 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15336 2001-08-31 Akim Demaille <akim@epita.fr>
15338 * bin/autoheader.in: Rewrite in Perl.
15339 * tests/autoheader: Adjust.
15341 2001-08-31 Akim Demaille <akim@epita.fr>
15343 * bin/autoconf.in (--include, -I): New option.
15344 Map --localdir, --autoconf-dir onto it.
15345 Forward autom4te's options instead of interpreting them.
15346 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15347 There is no such envvar since the inception of autom4te.cfg.
15348 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15349 * bin/autoupdate.in: Adjust, and perform more control.
15350 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15351 * tests/autoconf: Dittowise.
15353 2001-08-31 Akim Demaille <akim@epita.fr>
15355 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15356 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15357 optionally `FILE'.
15358 Use -e, not -f, since /dev/null for instance is OK.
15359 (&parse_args): Adjust.
15360 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15362 2001-08-31 Akim Demaille <akim@epita.fr>
15364 * configure.ac: Also find tested executables in bin.
15365 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
15366 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
15367 installed peer executables, only PATH is allowed to resolve it.
15368 Pass `autoconf_dir' via options, not via invisible envvars.
15369 * lib/Autom4te/General.pm (&find_peer): Remove.
15370 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15371 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15372 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15373 find the executables for it.
15374 * tests/Makefile.am: Major cleanup. Too lazy to document...
15375 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15376 We only need PERL.
15377 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15378 indeed related to running the test suite, while passing
15379 --autoconf-dir and others is related to running non installed
15380 Autoconf executables. So don't do that, leave it to...
15381 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15382 * tests/autoscan: New.
15383 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15384 refer to library files: rely on --language.
15386 2001-08-29 Akim Demaille <akim@epita.fr>
15388 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
15389 s/--set/--language/.
15391 2001-08-29 Akim Demaille <akim@epita.fr>
15393 * doc/autoconf.texi: Strip the @nodes.
15394 Suggested by Paul Eggert.
15395 (Initializing configure): Typo.
15397 2001-08-29 Akim Demaille <akim@epita.fr>
15399 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15400 Suggested by Paul Eggert.
15402 2001-08-29 Akim Demaille <akim@epita.fr>
15404 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15405 download in a tmp dir.
15407 2001-08-29 Akim Demaille <akim@epita.fr>
15409 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
15410 case insensitive OSes out there :(
15411 From Tim Van Holder.
15413 2001-08-29 Akim Demaille <akim@epita.fr>
15415 * lib/autom4te.in: New.
15416 * lib/Makefile.am (edit, autom4te.cfg): New.
15417 * bin/autom4te.in (BEGIN): Simplify.
15418 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
15419 (&load_configuration): New. Use it.
15420 (&parse_args): Support --mode, --set, and --melt.
15421 * bin/autoconf.in: Simplify and adjust.
15422 * tests/Makefile.am (AUTOMAKE): Use --set.
15423 * tests/atlocal.in: Adjust.
15424 * BUGS: distcheck and check are weak.
15426 2001-08-29 Akim Demaille <akim@epita.fr>
15428 * lib/autotest/general.m4: Use
15429 foo=`(command) 2>/dev/null`
15430 not
15431 foo=`command` 2>/dev/null
15432 (at-devnull): Rename as...
15433 (AT-devnull): this.
15434 (--clean): Remove AT-* files too.
15435 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
15436 Reported by Nicolas Joly.
15438 2001-08-28 Akim Demaille <akim@epita.fr>
15440 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
15441 quotes inside single quotes.
15442 Reported by Nicolas Joly.
15444 2001-08-28 Kevin Ryde <user42@zip.com.au>
15446 * doc/autoconf.texi (Function Portability): Mention C right shifts.
15448 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
15450 * lib/autotest/general.m4: Reword some messages.
15451 (AT_INIT): Check for the `times' builtin before using it.
15452 Support test ranges as arguments to the testsuite.
15453 Have -e imply -d as the help text suggested.
15455 2001-08-27 Akim Demaille <akim@epita.fr>
15457 * Makefile.maint: Formatting changes.
15458 (do-po-update, po-update, cvs-update, update): New targets.
15459 (AMTAR): Remove.
15461 2001-08-27 Akim Demaille <akim@epita.fr>
15463 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

15470 * lib/autotest/general.m4 (AT_INIT): Log the command line.
15471 Support `VAR=VAL' as arguments.
15472 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
15473 may be set via the command line.
15475 2001-08-27 Akim Demaille <akim@epita.fr>
15477 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
15478 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
15479 first the build dirs, then the src dirs.

15482 2001-08-27 Akim Demaille <akim@epita.fr>
15484 * lib/autotest/general.m4 (AT_INIT): Output the definition of
15485 at_data_files earlier.

15489 2001-08-27 Akim Demaille <akim@epita.fr>
15491 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
15492 `ac_top_builddir' to mimic Automake's vocabulary, which much more
15493 readable.
15494 Adjust callers.
15495 * doc/autoconf.texi (Configuration Actions): Document the vars
15496 available in commands.
15497 Emphasize the risks of collisions in init-cmds.

15502 (Initializing configure): this new node.
15504 2001-08-27 Akim Demaille <akim@epita.fr>

15517 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

15527 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
15528 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
15529 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
15530 -> ac_dir).
15531 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
15532 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
15534 2001-08-27 Akim Demaille <akim@epita.fr>

15559 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
15560 (AMTAR): Help automake define it.
15561 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
15562 needed, 1.5 can have a macro and a target with the same name.
15563 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
15564 * m4/strip.m4: New.

15577 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
15578 Adjust callers.
15579 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15580 the name of the directory they're in, instead of the filename,
15581 since version.m4 is now in m4sugar, but m4_acversion must not be
15582 classified as an Autoconf macro.
15583 ($input_m4): Don't qualify the path to m4sugar.
15584 Rather, pass autoconf_dir to m4.
15585 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
15586 * tests/suite.at: Require 2.52c.
15588 2001-08-27 Akim Demaille <akim@epita.fr>

15600 of config.log on traps.
15601 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
15602 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
15603 for config.status'.
15604 Open the log as soon as possible.
15605 Use the same log introduction as configure's.
15607 2001-08-22 Paul Eggert <eggert@twinsun.com>
15609 * doc/autoconf.texi (Indices): New node.
15610 Move indices out of the top level menu and into this submenu.
15612 2001-08-22 Akim Demaille <akim@epita.fr>
15614 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
15615 AC_TRY_COMMAND.

15669 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
15670 * NEWS, README, README-alpha, TODO, tests/README: This package is
15671 `Autoconf', not `autoconf' (the executable).
15673 2001-08-20 Akim Demaille <akim@epita.fr>
15675 Info readers seem to need `Index' in the index node title :(
15677 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15678 simplified index node names.
15680 2001-08-20 Akim Demaille <akim@epita.fr>

15722 2001-08-20 Akim Demaille <akim@epita.fr>
15724 Huh!?!?! There are still some user EOF tags used, which prevents
15725 their use in AC_CONFIG_COMMANDS for instance...
15727 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15728 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
15729 `_CSEOF', or `_ATEOF', as appropriate.

15789 2001-08-17 Akim Demaille <akim@epita.fr>
15791 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
15792 `$0.log' as for projects where testsuite is in src, we'd have
15793 testsuite.log created in src.

15807 2001-08-17 Akim Demaille <akim@epita.fr>
15809 * doc/autoconf.texi: Work around Texinfo buglets.
15810 (Transformation Rules): One example is enough, users are expected
15811 to have their brains on. And BTW, use DESTDIR.
15812 (dvar): New macro. Use it.
15814 2001-08-17 Akim Demaille <akim@epita.fr>
15816 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15822 * bin/autom4te.in: --normalize is a new option.
15823 * bin/autoconf.in: Use it.

15832 * doc/autoconf.texi, doc/install.texi: Put copyright notice at

15835 2001-08-15 Akim Demaille <akim@epita.fr>
15837 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
15838 Use it.
15840 2001-08-15 Akim Demaille <akim@epita.fr>

15849 * doc/install.texi: Use @command.

15853 2001-08-15 Akim Demaille <akim@epita.fr>
15855 * doc/autoconf.texi (Function Portability): sprintf's return
15856 value.
15857 From Kevin Ryde.
15859 2001-08-15 Akim Demaille <akim@epita.fr>
15861 * Makefile.maint (CVS): New.
15862 (local-check): Run changelog-check. last.
15863 (alpha): Don't depend upon local-check, since...
15864 (cvs-dist): depends upon it.
15866 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15868 * tests/Makefile.am: Use a clean-local rule to remove
15869 autom4te.cache (it's a directory, not a file.
15870 * Makefile.am: Ditto (but maintainer-clean-local).
15872 2001-08-15 Akim Demaille <akim@epita.fr>
15874 * bin/autom4te.in (@m4_warning): New.
15875 (&handle_m4): Use it.
15876 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15877 warnings are issued at each run.
15878 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15879 is in the src tree.
15881 2001-08-15 Akim Demaille <akim@epita.fr>
15883 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15884 don't waste time running `autoupdate --version' works.
15885 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15887 2001-08-13 Akim Demaille <akim@epita.fr>
15889 * doc/autoconf.texi (ma): Rename this index as...

15903 duration of the test suite.
15905 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15907 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
15908 endianness for comparison instead of relying on AT_CHECK_ENV.
15910 2001-08-11 Paul Eggert <eggert@twinsun.com>
15912 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
15913 to the INSTALL file.
15915 2001-08-11 Paul Eggert <eggert@twinsun.com>

15940 * tests/mktests.sh: Update year in copyright notice.
15942 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15944 * tests/semantics.at (AC_C_BIGENDIAN): New test.
15946 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15948 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15949 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15950 * doc/autoconf.texi (C Compiler Characteristics): Update
15951 documentation for AC_C_BIGENDIAN.
15953 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15955 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15956 magic values from an object file when cross-compiling.
15957 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15959 2001-08-10 Akim Demaille <akim@epita.fr>
15961 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15962 effects.
15963 Suggested by Russ Allbery.
15965 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15967 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15968 current $prefix to the sub-configures.
15970 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15972 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15973 extension (needed on BeOS). Reported by Guido van Rossum.
15975 2001-08-09 Akim Demaille <akim@epita.fr>
15977 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15979 2001-08-07 Akim Demaille <akim@epita.fr>
15981 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15982 removed.
15983 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15984 No need to remove the files before and after the each test, before
15985 each test and at the end of the suite is enough.
15986 Display only the children `times', not the shell's.
15987 If the test failed or was skipped, at-times is not available.
15989 2001-08-07 Akim Demaille <akim@epita.fr>
15991 Always produce testsuite.log, including when there are no
15992 failures. This helps getting information on skipped tests, and
15993 duration of the tests. Err, implement the latter btw.
15995 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15996 Dump information on the first run of each test.
15997 (AT_CLEANUP): Create `at-times' containing the duration of the
15998 test group.
16000 2001-08-07 Akim Demaille <akim@epita.fr>
16002 The use of `dumpstat' revealed that `len' was used although it
16003 should not. m4_text_wrap was using it, but in the Autoconf world
16004 where it is legal. Hence (i) test M4sh in its own world, not
16005 Autoconf's, and (ii), ahem, fix the bug :)
16007 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
16008 does not like `' instead of [].
16009 (AT_INIT): Forbid `^_?AT_'.
16010 And don't output such tokens.
16011 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
16012 `script.as', and `autom4te.cache'.
16013 Remove `empty' and `macro' which are no longer used.
16014 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
16015 * tests/m4sugar.at: Use it.
16016 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
16018 2001-08-07 Akim Demaille <akim@epita.fr>
16020 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
16022 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
16024 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
16026 2001-08-04 Akim Demaille <akim@epita.fr>
16028 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
16029 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
16030 AC_TRY_LINK.
16031 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
16032 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
16033 (AC_F77_MAIN): Likewise.
16035 2001-08-04 Akim Demaille <akim@epita.fr>
16037 Don't rely on M4sugar outputting the patterns in files, since we
16038 might process the output _without_ running m4, hence without these
16039 files.
16041 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
16042 * bin/autom4te.in (@Request::includes): Remove, unused.
16043 (@Request::source): Rename as...
16044 (@Request::input): this.
16045 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
16046 (&handle_output): Fetch the patterns from the traces.
16047 `$forbidden' and `$allowed' are constant: use m//o.
16048 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
16049 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
16051 2001-08-04 Akim Demaille <akim@epita.fr>
16053 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
16054 autoconf', i.e., in addition to caching traces, cache the output.
16056 * bin/autom4te.in (Request::cache): Rename as...
16057 (Request::id): this.
16058 ($cache, $icache, $tcache, $ocache): New.
16059 (&handle_m4): Save M4 output in the cache instead of $tmp.
16060 (&handle_output): Adjust.
16061 (&up_to_date_p): Check that the output cache is up to date too.
16062 (top level): Run `&handle_m4' iff force or the cache is invalid.
16063 Run `&handle_output' if the output cache is more recent.
16065 2001-08-04 Akim Demaille <akim@epita.fr>
16067 * bin/autom4te.in ($force): New.
16068 (&parse_args, &print_usage): -f, --force is a new option.
16069 (&handle_output): CPP directives might have spaces after `#'.
16070 (&parse_args): The first file only can be frozen.
16072 2001-08-04 Akim Demaille <akim@epita.fr>
16074 Don't let autom4te compute the `include' traces several times:
16075 first check that the trace cache file is up to date, and then
16076 compare its timestamp with that of the output.
16078 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16079 the preamble. Don't require 5.005 as Autom4te::General does it,
16080 and better yet (use `use', not `require'!).
16081 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16082 Class::Struct as Autom4te::Struct.
16083 * lib/Autom4te/General.pm (File::stat): Use it.
16084 (&mtime): New, export it.
16085 * bin/autom4te.in: Use it.
16086 Declare `$req' is invalid if it is outdated.

16568 earlier if there are.
16570 2001-07-03 Akim Demaille <akim@epita.fr>

16603 provide an alternate 'main' function name, using the 'main' from

16606 cross-language link tests can be performed successfully.
16607 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
16608 after $LIBS, for consistency; this should be the general rule since
