1742 Cover more potentially problemtic file names. Use the new

1746 The test suite did not cover this bug because the code was not
1747 quoting properly the arguments of `rm -f' (which "fails" silently)
1748 as well as the arguments of `diff' (whose output was redirected to
1749 /dev/null so we couldn't see its error message).

1947 script executable if it is not complete.
1949 2007-12-12 Eric Blake <ebb9@byu.net>
1951 Fix thinko in earlier patch - m4_join isn't defined yet.
1952 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1953 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1954 (m4_require): Use m4_do, not m4_join.
1956 Fix some whitespace tests on cygwin.
1957 * tests/tools.at (autom4te and whitespace in file names): Restore
1958 font-lock. Create $TMPDIR before it might be used.
1960 Fix spurious testsuite failure with M4 1.4.11.
1961 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1963 Optimize AC_REQUIRE.
1964 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1965 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1966 (m4_require): Avoid extra macro calls.
1968 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1970 * tests/torture.at (srcdir): Fix quoting.
1972 Do not pass top_srcdir to configure scripts in testsuite.
1973 * tests/autotest.at (srcdir propagation): Copy install-sh to
1974 source tree.
1975 (my only test): Drop setting of `top_srcdir'.
1976 * tests/base.at (Input/Output): Likewise.
1977 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1978 config.guess, and config.sub to test source tree.
1979 Drop AC_CONFIG_AUX_DIR setting.
1980 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1981 * tests/torture.at (Substitute a 2000-byte string): Drop
1982 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1983 (Substitute a newline, datarootdir workaround): Likewise.
1984 (Define a newline): Adjust for linenumber changes in configure.ac.
1985 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1987 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1988 if `pwd` contains whitespace.
1990 Quote $abs_top_srcdir in tests.
1991 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1992 * tests/tools.at (Syntax of the shell scripts): Likewise.
1994 * tests/m4sh.at (LINENO): Quote $0.
1996 Fix testsuite program wrapper for whitespace in `pwd`.
1997 The problem here is that the usual mantra is that command
1998 variables can contain arguments, thus we cannot just escape
1999 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
2000 $top_builddir/tests directory early in $PATH, so that the
2001 wrappers are found by their plain name.
2002 * tests/wrapper.as: Put $testdir early in $PATH.
2003 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
2005 Proper config.status --file/--header and $srcdir escaping.
2006 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
2007 characters in $ac_file_inputs.
2008 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
2009 accordingly.
2010 * tests/torture.at (datarootdir workaround): Adjust.
2011 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
2013 Fix Autotest for whitespace in `pwd`.
2014 * lib/autotest/general.m4 (AT_INIT)
2015 <at_func_create_debugging_script, Driver Loop>:
2016 Quote $at_group_dir.
2017 * tests/autotest.at (whitespace in absolute testdir): New test.
2019 * lib/autom4te.in: Quote @datadir@.
2021 Proper file name escaping in Autoconf programs and Perl modules.
2022 This includes escaping of characters special to the shell
2023 as well as special to Perl, e.g., leading `<' or `>'.
2024 For example, when $file starts with `>', `open ">$file"'
2025 wrongly tries to append to a different file.
2026 * bin/autoconf.as: Fix quoting for autom4te options.
2027 * lib/Autom4te/General.pm (shell_quote): New function, taken
2028 from coreutils, written by Jim Meyering.
2029 (mktmpdir): Use it.
2030 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
2031 and open_quote.
2032 * bin/autoreconf.in (parse_args): Likewise.
2033 * bin/autoscan.in (main): Likewise.
2034 * bin/autoupdate.in (main): Likewise.
2035 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
2036 * bin/ifnames.in: Likewise, XFile usage fixes.
2037 * tests/tools.at (autom4te and whitespace in file names): Extend
2038 test. Test twice, with special characters allowed on w32, and the
2039 rest. Test leading and trailing whitespace, for `open_quote'.
2040 (autotools and whitespace in file names): New, analogous test.
2041 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
2042 by Russ Allbery and Eric Blake.
2044 Sync from Automake.
2045 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
2046 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
2047 * lib/Autom4te/FileUtils.pm (open_quote): New function.
2048 (update_file, contents): Use it.
2050 * Makefile.am (autom4te-update): Rewrite for git.
2052 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2054 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
2056 Fix copyright years.
2057 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
2058 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
2060 2007-12-04 Eric Blake <ebb9@byu.net>
2062 Manually resync with gnulib, since 'make cvs-update' no longer works.
2063 * build-aux/config.guess: New upstream version.
2064 * build-aux/config.sub: Likewise.
2066 When using older automake, don't downgrade build-aux/texinfo.tex.
2067 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
2068 * doc/Makefile.am (TEXINFO_TEX): Add.
2070 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2072 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2073 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2074 #undef as this runs afoul of our new way of creating config.h.
2075 Problem reported by Jim Meyering in
2076 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2078 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2080 Fix autom4te for unusual characters in input file names.
2081 * bin/autom4te.in (files_to_options): Quote active characters
2082 for the shell.
2083 * tests/tools.at (autom4te and white space in file names):
2084 New test.
2086 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2087 Document that Tru64 awk always splits $0.
2089 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2091 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2092 `#AT_STOP_...' line at the end of each test.
2094 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2096 * lib/autotest/general.m4 (AT_INIT): For awk line number
2097 extraction script, ensure `$at_group' has a defined value
2098 even for the empty set, and properly quote its usage inside
2099 the awk script.
2101 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2103 * doc/autoconf.texi (Shell Functions): New chapter. Document
2104 IRIX sh $0 issue in functions, move content from ...
2105 (Portable Shell): ... here.
2106 (Shell Script Compiler): Note that shell functions are not
2107 totally unportable any more.
2109 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2110 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2112 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2113 extracting the line numbers of the last needed test.
2115 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2117 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2118 Fix quoting.
2120 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2122 Fix IRIX testsuite debugging failures: $0 in functions.
2123 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2124 Do not use $0 inside a function, as IRIX sh will set that to the
2125 function name rather than the script invocation name.
2127 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2128 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2130 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2131 to extract test scripts.
2132 (AT_INIT): Extract and cache test script line numbers.
2134 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2136 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2137 subsequent fixups; the awk -> here-document conversion trashes
2138 performance too much with AIX sh.
2140 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2142 * tests/local.at: Do not test m4, perl with AT_TESTED.
2144 Diagnose and guard against write errors dealing with config.status.
2145 The general idea is this: all write failures from `configure'
2146 writing `config.status' are indicated by $ac_write_error, which
2147 is only checked at the end. This is safe because config.status
2148 code is not executed before the file is complete. Other write
2149 failures, be they inside config.status, or in sub shell/awk
2150 scripts spawned from configure or config.status, typically need
2151 earlier checking, as their results are used right afterwards.
2152 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2153 before writing config.status, check afterwards.
2154 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2155 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2156 Set `ac_write_error' for write failures to config.status. Barf
2157 upon write failures to temporary files.
2158 Adjust note about closing and reopening the here-document.
2159 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2160 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2161 reopening the here-document.
2162 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2163 Ensure `ac_write_error' does not escape into config.status.
2164 Also, add a couple of code paths not yet exercised in the test
2165 suite: a config file with input from stdin, and a config header
2166 output to stdout.
2167 Suggestion for catching write errors by Bruno Haible.
2169 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2171 Avoid error with Tru64 awk and testsuite lines with many words.
2172 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2173 reads the testsuite, set the field separator to an unusual value,
2174 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2175 even splits the input if $i, i>0, was never accessed in the script.
2177 Revert 2007-10-17 change.
2178 * TODO: Multiline args in config files and headers mean something
2179 different and are not fixed, see
2180 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2181 Report by Stepan Kasal.
2183 * doc/autoconf.texi (Generic Programs): Fix typo.
2185 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2187 AC_*_TOOL does not canonicalize the prefix
2188 * doc/autoconf.texi (Generic Programs): Do not say that
2189 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2191 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2193 Diagnose write errors in config.status instantiations.
2194 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2195 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2196 on write errors.
2197 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2198 Extend test to also check for some write error failures, using...
2199 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2200 Report by Bruno Haible.
2202 Indentation fixups.
2203 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2204 indentation.
2205 (_AT_CHECK): Use less indentation, to save space.
2207 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2209 Add witness macro for @top_build_prefix@ substitution.
2210 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2211 (_AC_OUTPUT_FILE): Mention it here.
2213 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2214 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2216 * lib/autotest/general.m4 (at_func_test): Remove.
2217 (AT_INIT): Pre-extract test groups into separate files.
2218 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2219 Remove at-test-source files together with the $at_group_dir.
2220 * tests/autotest.at (Long test source lines): New test.
2222 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2224 Shell functions and variables may share a namespace.
2225 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2226 limitation.
2228 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2230 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2231 gnulib.
2233 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2235 * lib/autoconf/status.m4: Fix a couple of comment typos.
2237 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2239 2007-11-13 Jim Meyering <meyering@redhat.com>
2241 Clean up the rule to create "expr".
2242 * tests/Makefile.am (expr): Don't redirect directly to target.
2243 Redirect just once, not for each echo statement.
2244 Use $@, not literal "expr".
2246 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2248 Don't worry about preprocessor when testing long long.
2249 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2250 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2251 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2252 These no longer check for preprocessor flaws.
2253 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2254 Do not check for preprocessor flaws.
2256 2007-11-13 Jim Meyering <meyering@redhat.com>
2258 Adapt dependencies, now that a version change doesn't modify configure.ac
2259 * GNUmakefile: Remove "make clean" kludge.
2260 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2261 configure.ac.
2262 Don't redirect directly to target.
2263 Use $@, not literal "version.m4".
2265 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2267 * doc/autoconf.texi (Making testsuite Scripts): Document
2268 ":;{" shorthand as in previous patch.
2270 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2272 * doc/autoconf.texi (Limitations of Builtins): Document problem
2273 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2274 for the workaround.
2275 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2276 Use ":;{" shorthand.
2277 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2279 2007-11-12 Jim Meyering <meyering@redhat.com>
2281 Add more non-srcdir build support.
2282 * GNUmakefile (dummy): Split a long line.
2283 Add -v option to autoreconf invocation.
2285 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2286 * GNUmakefile (dummy): Remove INSTALL.
2288 Remove racy commands to build scripts in bin/ and tests/.
2289 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2290 are guaranteed to be built, remove the rules that tried to build
2291 them. Before, with a parallel build, these rules could lead to
2292 two processes writing tests/wrapper.in concurrently.
2294 Build in man/ only *after* building in bin/ and tests/.
2295 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2296 in both bin/ and tests/.
2298 Accommodate non-srcdir build-from-checkout.
2299 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2300 Use git's --git-dir=$srcdir/.git option.
2301 Add quotes, in case tarball_version_file contains shell meta-characters.
2302 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2303 * configure.ac: Pass "." to git-version-gen.
2305 Avoid spurious test failures due to version skew.
2306 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2308 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2310 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2311 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2312 Remove conftest.dSYM directory.
2313 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2314 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2315 Remove `conftest.*' recursively.
2316 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2317 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2318 Likewise.
2319 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2320 * THANKS: Update.
2321 Report and analysis by Jeff Squyres and Peter O'Gorman.
2323 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2325 Fix typos in variable names.
2326 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2328 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2330 Document that $((expression)) is not portable.
2331 * doc/autoconf.texi (Shell Substitutions): Here.
2333 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2335 Ignore configure --help* errors due to LINENO-impaired shells.
2336 * tests/torture.at (Configuring subdirectories, Deep Package):
2337 In the --help* tests in read-only trees, make `.' temporarily
2338 writable again for the `stderr' file, and ignore errors due to
2339 the attempt to write configure.lineno.
2340 Report by Patrick Welche.
2342 2007-11-10 Jim Meyering <meyering@redhat.com>
2344 Generate package.m4 in build-dir, not srcdir.
2345 * tests/Makefile.am (package.m4): Adjust target.
2346 Don't redirect directly to $@.
2347 (CLEANFILES): Add package.m4.
2348 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2349 in $(srcdir).
2350 When running $(AUTOTEST), search "." before searching $(srcdir).
2352 Avoid a race condition that would make parallel "distclean" fail.
2353 * tests/Makefile.am (distclean-generic): Replace the default,
2354 automake-provided rule with an identical one, but with an additional
2355 dependency on distclean-local. Simply adding the dependency would
2356 cause automake not to emit the rule at all.
2357 * BUGS: Building with -jN works, now.
2359 Distribute git-version-gen.
2360 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2361 since GNUmakefile is distributed, and requires it for dist* rules.
2363 Remove two more generated files from version control.
2364 * INSTALL: Remove generated file.
2365 * lib/autoscan/autoscan.list: Remove generated file.
2367 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2369 * GNUmakefile (PATH): Remove stray apostrophes; they become
2370 part of PATH, which isn't wanted here.
2372 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2374 New config files output variable `top_build_prefix'.
2375 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2376 `top_build_prefix'.
2377 * doc/autoconf.texi (Preset Output Variables): Document it.
2378 * NEWS: Update.
2379 Report by Bob Friesenhahn.
2381 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2382 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2383 function, to parametrize arithmetic with expr vs. the shell.
2384 Use it where possible.
2385 Suggestion by Benoit Sigoure.
2387 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2389 Adjust the documentation of autotest WRT atlocal.
2390 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2391 when using Automake, to write a rule to produce atlocal, since it's
2392 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2393 distributed, not atconfig.in.
2395 2007-11-04 Eric Blake <ebb9@byu.net>
2397 Update list information.
2398 * README: Mention new autoconf-commit list.
2399 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
2401 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2403 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
2405 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
2407 * build-aux/.gitignore: Ignore mkinstalldirs.
2409 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
2411 2007-11-03 Jim Meyering <meyering@redhat.com>
2413 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
2414 * build-aux/git-version-gen: This syncs from coreutils.
2416 Adjust the build procedure so "make check" works reliably.
2417 * README-hacking: Include an extra step between "make" and
2418 "make check" to ensure that the latter passes.

2494 Make inter-release --version output more useful.
2496 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2497 which indicates that it is built using the 19th change set
2498 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2499 is a prefix of the commit SHA1.
2500 * build-aux/git-version-gen: New file.

2511 git-version-gen doesn't match $(VERSION), but only for dist targets.

2553 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2555 Don't check for bug in HP-UX 11.00 cpp.
2556 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2557 Use -1ull rather than -1u, since that causes problems with gnulib; see

2581 configure script to be found in $PATH, if the shell does not do
2582 this resolution. Fixes test failure on FreeBSD.
2584 Fix config header generation with AIX awk.
2585 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2586 script, use helper array D_is_set, as `" 0"' does not evaluate

3767 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look

3783 * doc/autoconf.texi (Generic types): C types must be type-names
3784 (the C terminology), not type-ids (the C++ term). C++ types
3785 must not be anonymous.
3786 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
3787 for C++; this drops support for anonymous struct and union types,
3788 which were problematic anyway.
3789 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even

3807 with objects too. Document the restrictions on its use.
3808 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
3809 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3810 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3811 works but the latter doesn't, then it's a valid type.
3812 This lets people use function types and so forth.
3813 For C++ there doesn't seem to be a simple solution, so leave it alone.
3814 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3815 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3816 AC_CHECK_TYPE; that wasn't documented or necessary.

3877 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3879 * doc/autoconf.texi (Specifying Names): `--host' does not
3880 change the build type.
3882 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3884 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3885 suggests AC_CONFIG_HEADERS.

3986 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3987 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3988 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3989 substitution will still be done by the special code.
3990 Report by Jim Meyering.

4009 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
4011 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4013 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
4014 early on the reader side, drop stderr of the input to avoid
4015 `broken pipe' error output; this may happen even with shell
4016 builtin `echo' of some bash versions. Reports by Ian Macdonald
4017 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
4019 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4021 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
4022 separate items of `ac_user_opts', to avoid long lines.
4023 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.

4029 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
4031 Fix some wording problems noted by Paolo Bonzini in:
4032 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
4033 * doc/autoconf.texi (Signed Overflow Examples): Give more
4034 discussion about the allow_superuser_privileges example,
4035 and change it a bit to make things clearer.
4036 (Optimization and Wraparound): Clarify whether the compiler
4037 will generate an infinite loop for the example derived from
4038 Autoconf's mktime test.
4039 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
4040 Also, clarify unsigned multiplication overflow.
4042 2007-01-04 Eric Blake <ebb9@byu.net>
4044 * bin/Makefile.am (RELEASE_YEAR): New macro.
4045 (edit): Use it to supply correct copyright year to scripts.
4046 * bin/autoconf.as (version): Use it.
4047 * bin/autoheader.in ($version): Likewise.
4048 * bin/autom4te.in ($version): Likewise.
4049 * bin/autoreconf.in ($version): Likewise.
4050 * bin/autoscan.in ($version): Likewise.
4051 * bin/autoupdate.in ($version): Likewise.
4052 * bin/ifnames.in ($version): Likewise.
4054 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4056 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4057 feedback. The most important changes document what happens when
4058 you convert an out-of-range value to a signed integer type, and
4059 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4060 a + b.
4062 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4063 rewrite, taking notions from the recent discussion on the gcc and
4064 autoconf mailing lists; please see
4065 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4066 and follow the many links.
4067 (Integer Overflow Basics, Signed Overflow Examples):
4068 (Optimization and Wraparound, Signed Overflow Advice):
4069 (Signed Integer Division): New sections.
4071 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4073 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4074 preprocessor macro arguments in traced name.
4075 * doc/autoconf.texi (Defining symbols): Document longstanding
4076 support for AC_DEFINE-ing macros with arguments, and document
4077 behavior when the same variable has multiple AC_DEFINEs.
4078 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4079 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4080 macros directly, giving much shorter and simpler code.
4082 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4084 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4085 space before "$ac_configure_args" to prevent a 'config.status
4086 --recheck' failure if ac_configure_args doesn't contain a leading
4087 space. This works around a problem with the XEmacs configure.ac,
4088 which uses the (undocumented) ac_configure_args variable
4089 inconsistently with Autoconf.
4091 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4093 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4094 Include <limits.h>, and use its INT_MAX to rewrite the
4095 j loop so that it does not overflow 'int'. Problem reported by
4096 Ralf Wildenhues in
4097 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4098 Play it safe by shifting left by 1 rather than multiplying by 2,
4099 as GCC is less likely to optimize this away when the value
4100 is signed (when it assumes overflow leads to undefined behavior).
4101 Also, don't assume time_t uses two's complement.
4103 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4105 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4106 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4107 dumps core on it. Report by Tim Rice.
4109 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4111 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4112 --disable-option-checking to --help output even when
4113 AC_PRESERVE_HELP_ORDER is not used.
4114 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4115 --with argument, rather than argument with [-.] replaced by
4116 underscores.
4117 * NEWS: Fix typo in previous change; the news was in the
4118 wrong section.
4120 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4122 * NEWS: Warnings are now generated by default for unknown
4123 --enable-* and --with-* options.
4124 * doc/autoconf.texi (Option Checking): Renamed from
4125 (Configure Option Checking). Tighten up the wording a bit.
4126 (External Software, Package Options): Cross-reference to Option
4127 Checking, and use this to shorten our section.
4128 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4129 "$x" to test "x$foo" != x.
4130 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4131 Don't warn if $enable_option_checking is "no".
4132 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4133 ac_unrecognized_opts to the empty string.
4134 Don't echo the unrecognized opts, as this might mishandle
4135 backslashes or leading -.
4136 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4137 usage next to the other --disable-FEATURE options in the
4138 help string.
4140 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4142 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4143 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4144 Print warning for unrecognized --with and --enable options
4145 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4146 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4147 Disable option checking when subdirs are configured.
4148 (AC_OUTPUT): If warnings are enabled, print warning about
4149 unrecognized --with and --enable options at the end of
4150 the configure output (as well as at the beginning).
4151 * doc/autoconf.texi (Option Checking): New node.
4152 Document new option warning functionality.
4154 2006-12-16 Eric Blake <ebb9@byu.net>
4156 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4157 * NEWS: Start news for current version.
4159 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4161 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4162 Define HAVE_GETMNTENT to 1, not to the empty string.
4163 Problem originally reported by Jochen Friedrich in
4164 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4166 This change prompted by a problem report by Andrey Simonenko in
4167 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4168 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4169 object-like macros only, in the traditional portable character
4170 set.
4171 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4172 Warn about attempts to define things that are not identifiers.
4173 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4174 awful hack that AC_DEFINEd macro names containing parentheses.
4176 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4178 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4179 too drastic, even if Texinfo in theory requires it for info mode.
4181 (config.status Invocation): Renamed back from Recreating a
4182 Configuration).
4183 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4184 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4186 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4188 * NEWS: Version 2.61a.
4190 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4191 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4193 * NEWS: Document changes with echo and printf, and the lack
4194 of limits on the total size of multi-line values of substituted
4195 variables, and the AC_FUNC_FSEEKO fix.
4197 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4199 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4200 Writing configure.ac.
4201 (Autoconf Input Layout): Renamed from configure.ac Layout.
4202 (Recreating a Configuration): Renamed from config.status Invocation.
4203 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4204 (acconfig Header): Renamed from acconfig.h.
4205 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4206 (Writing Testsuites): Renamed from Writing testsuite.at.
4207 (Autom4te Cache): Renamed from autom4te.cache.
4209 * BUGS: Remove mention of VPATH problem, since it's now documented
4210 not to be a bug in the Autoconf build procedure itself, but rather
4211 a problem with the proprietary `make' programs.
4213 * doc/autoconf.texi (Build Directories): Add a cross reference
4214 to VPATH and Make.
4216 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4217 * doc/standards.texi: Sync from gnulib.
4219 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4220 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4221 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4222 generated automatically.
4224 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4226 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4227 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4228 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4230 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4232 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4233 `CEOF$ac_eof' special marker, the awk script cannot contain a
4234 line matching `^CEOF', so this is not needed any more.
4235 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4236 special marker in the test.
4238 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4240 * tests/tools.at (autom4te preselections): Use `find -newer';
4241 remove one of the sleeps.
4243 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4244 more readable, using ...
4245 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4247 * doc/autoconf.texi (autoheader Invocation): Do not double-
4248 quote the parameter of `AH_BOTTOM' in the example.
4250 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4252 * doc/autoconf.texi (Configuration Headers): Remove the
4253 example with multiple input files.
4254 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4255 multiple input files.
4257 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4260 creating the awk substitution script, handle one input line at a
4261 time, so that the maximum length of a substituted (multi-line)
4262 value is not limited by the size of the sed pattern space.
4263 The trade-off is a slightly repetitive sed script.
4264 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4265 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4266 * tests/torture.at (Substitute a 2000-byte string): Increase the
4267 test with several long lines, they should not be caught by sed
4268 limits any more.
4270 * tests/tools.at (autom4te preselections): New test, to flag
4271 entries missing from autom4te.cfg.
4272 Report by David Byron <dbyron@hheld.com>.
4274 * tests/torture.at (Substitute a 2000-byte string): Actually use
4275 AC_PROG_AWK, so the last change works as intended.
4276 (Substitute and define special characters): Likewise.
4277 (Substitute a newline): Likewise.
4279 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4280 instead of `awk' consistently.
4281 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4282 * tests/torture.at (Torturing config.status): Test both the
4283 result of AC_PROG_AWK and plain awk.
4284 (Substitute a 2000-byte string): Likewise.
4285 (Substitute and define special characters): Likewise.
4286 (Substitute a newline): Likewise.
4288 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4290 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4291 can be assigned to a function pointer. Problem reported by
4292 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4293 part of a patch by Ralf Wildenhues in that same bug report.
4295 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4297 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4298 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4300 2006-12-01 Eric Blake <ebb9@byu.net>
4302 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4303 cross-compiling from cygwin to mingw.
4304 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4305 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4306 to lib/autoconf/c.m4.
4308 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4310 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4311 string for more reliable failure. Wrap the entire test that
4312 causes the broken Solaris printf to dump core, in a subshell,
4313 so the segmentation fault message is reliably suppressed.
4314 Fix shell expansion errors by using /usr/ucb/echo always;
4315 avoid an error on systems without it by another subshell.
4316 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4317 subshell-$as_echo to `as_echo', for better error message.
4319 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4321 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4322 `BASH_SOURCE' contain a newline, set them to empty, as they may
4323 not be unset.
4325 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4327 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4328 years and is too hard to maintain now. The last straw was
4329 reported by Jerker Baeck in
4330 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4331 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4332 * doc/autoconf.texi (Particular Functions): Move
4333 AC_FUNC_SETVBUF_REVERSED from here...
4334 (Obsolete Macros): ... to here. Say that it does nothing now.
4335 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4336 Turn into (almost) a no-op.
4338 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4339 (AC_C_VOLATILE):
4340 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4341 These macros are obsolescent and new applications shouldn't need them.
4342 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4343 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4344 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4345 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4346 (AC_FUNC_VPRINTF): Likewise.
4347 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4348 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4349 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4351 * doc/autoconf.texi (Setting Output Variables): Mention that
4352 @VAR1@VAR2 has unspecified behavior. Problem reported by
4353 Ralf Wildenhues.
4354 * NEWS: Mention this.
4356 * Makefile.am: Put only a single '#' into the copyright notice,
4357 so that it's also present in the output file. Standardize wording
4358 in makefile copyright notices to match GNU coding standards.
4359 * bin/Makefile.am: Likewise.
4360 * doc/Makefile.am: Likewise.
4361 * lib/Makefile.am: Likewise.
4362 * lib/freeze.mk: Likewise.
4363 * lib/autoconf/Makefile.am: Likewise.
4364 * lib/autoscan/Makefile.am: Likewise.
4365 * lib/autotest/Makefile.am: Likewise.
4366 * lib/m4sugar/Makefile.am: Likewise.
4367 * man/Makefile.am: Likewise.
4368 * tests/Makefile.am: Likewise.
4369 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4370 one-line file.
4372 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4374 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4375 in the sed script that mangles the awk script: delete up to the
4376 first exclamation mark only.
4377 * tests/torture.at (Substitute and define special characters):
4378 Test '!' too.
4380 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4382 Rewrite config files generation: avoid quadratic growth in
4383 the number of substituted variables by using awk instead of sed
4384 for the bulk of the substitutions.
4385 * NEWS: Mention this.
4386 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4387 forbidden in the output (and thus input) file.
4388 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4389 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4390 generate just one large awk script for substitutions,
4391 eliminating much of the earlier complexity, while adding some
4392 new complexity. Only expand the substitution templates at
4393 configure time, for smaller configure script size. If
4394 _AC_SUBST_FILES are used, test 'awk' for working getline support
4395 at config.status time. If absent, interpolate through the
4396 shell. The awk script was written with much help
4397 from Paolo Bonzini and Paul Eggert.
4398 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4399 (_AC_SED_FRAG_NUM): Likewise.
4400 (_AC_SUBST_CMDS): Renamed from...
4401 (_AC_SED_CMDS): ...this.
4402 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4403 * tests/torture.at (Substitute a 2000-byte string): Also
4404 substitute a line with 1000 words, and a variable with several
4405 long lines.
4406 (Substitute and define special characters): Test awk special
4407 characters, and put substitution input strings `@foo@' in the
4408 output, to test that no recursion happens; test several other
4409 combinations from Paolo Bonzini.
4411 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4413 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4414 that replaced echo with AS_ECHO where this wasn't necessary.
4415 Problem reportd by Ralf Wildenhues.
4416 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4417 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4418 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4420 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4422 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4424 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4426 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4427 that traditional Awk lacks 3-arg "split". It has it.
4428 Mention that FS must be a single character, and a few other
4429 99-byte limits of traditional Awk.
4430 Mention that if (i in a) doesn't work with traditional Awk.
4432 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4434 * tests/autotest.at (BSx641-newline in command):
4435 (BS-BS-newline in command, BSx640-newline in command):
4436 (Newline-CODE-BS-newline in command):
4437 (Single-quote-BS-newline in command):
4438 (Single-quote-newline-BS-newline in command):
4439 Use printf '%s\n' instead of echo, for portability to hosts
4440 where echo interprets backslashes. This will break on hosts
4441 that lack printf, but for now let's assume all such hosts
4442 are dead (if not, we should get reports of test failures).
4444 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4446 'echo' has some portability problems, when given a first argument
4447 with a leading '-', or when given any argument containing '\'.
4448 Avoid using 'echo' in these cases.
4449 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4450 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4451 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4452 * lib/autotest/general.m4 (AT_INIT): Likewise.
4453 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4454 argument might be unportable.
4455 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
4456 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

4458 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
4459 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
4460 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):

4469 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
4470 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.

4473 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4474 * bin/autoconf.as: Redo verbose flag implementation, as the old
4475 scheme wouldn't work with AS_ECHO.
4476 * lib/autotest/general.m4 (AT_INIT): Likewise.
4477 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4478 Don't use ECHO_T, since ECHO_N is now reliable.
4479 * lib/autotest/general.m4 (AT_INIT): Likewise.
4480 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4481 rather than using a here-document to put the script into a file.
4482 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4483 use AS_ECHO.
4484 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4485 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4486 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4487 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4488 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4489 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4490 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4491 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4492 operand, as AS_ECHO requires. Avoid double file name expansion.
4493 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4494 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4495 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4496 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4497 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4498 Double-quote strings that would otherwise contain M4 comments.
4499 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4501 * configure.ac (AC_INIT): Bump to 2.61a.
4502 * NEWS: Likewise.
4504 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4506 Version 2.61.
4508 * configure.ac (AC_INIT): Bump to 2.61.
4509 * NEWS: Likewise.
4511 * tests/autotest.at (Macro with backslash in a test title):
4512 Comment out for now, as this tests neither fails nor passes
4513 reliably. Problem reported by Ralf Wildenhues.
4515 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4517 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4518 in previous change, which caused test failures.
4520 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4522 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4523 code for --enable, --disable, --with, and --without to...
4524 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4525 * doc/autoconf.texi (Package Options):
4526 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4528 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4530 Import these changes from config via gnulib:
4532 2006-11-15 Ben Elliston <bje@gnu.org>
4534 From Josselin Mouette <joss@debian.org>:

4565 Import these changes from texinfo via gnulib:
4567 2006-11-08 Karl Berry <karl@gnu.org>
4569 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
4570 as well as pdf images, since they are supported in pdftex with
4571 no further ado.
4573 2006-11-05 Karl Berry <karl@gnu.org>
4575 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

4587 first argument may also contain dots.
4589 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4591 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4592 benefit of platforms like Solaris+GCC where it is common to have a
4593 non-working g++ installation.
4595 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4596 and Joel E. Denny <jdenny@ces.clemson.edu>
4597 and Paul Eggert <eggert@cs.ucla.edu>
4599 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4600 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4601 ./micro-suite.
4603 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4605 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4606 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4607 Imported from a similar patch to gnulib by Bruno Haible.
4609 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4611 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4619 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
4620 Matthew Woehlke.
4622 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4624 * tests/torture.at (Configuring subdirectories): Do not skip
4625 Automake 1.10 nor future Automake 11.1 (sic).
4627 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4628 and Stepan Kasal <kasal@ucw.cz>
4630 Handle special characters in test case titles correctly.
4631 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4632 properly.
4633 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4634 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4635 argument. Extend to check titles printed by ./micro-suite and
4636 ./micro-suite -l and the title in micro-suite.log.
4637 (Backquote in a test title,
4638 Single-quote in a test title,
4639 Double-quote in a test title): Don't expect failure anymore.
4640 (Backslash in a test title): Put a non-whitespace character after the
4641 backslash so that Bourne shells might actually see it as an escape
4642 sequence.
4643 (Brackets in a test title,
4644 Pound in a test title,
4645 Comma in a test title,
4646 Quoted Macro in a test title,
4647 Macro in a test title,
4648 Macro with single-quote in a test title): New tests.
4649 (Macro with backquote in a test title,
4650 Macro with double-quote in a test title,
4651 Macro with backslash in a test title): New tests expected to fail.
4652 * tests/torture.at (#define header templates): M4-quote this title in
4653 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4654 The visible effect was a stray [] in the testsuite output.
4656 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4658 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4659 `trap ... 0' inside a function, for AIX sh.
4661 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4663 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4664 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4665 5363) simply issues a warning when dividing by zero at compile
4666 time. Problem reported by Elias Pipping.
4668 2006-10-26 Eric Blake <ebb9@byu.net>
4670 * THANKS: Update.
4671 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4672 show effect on macros that expand with commas.
4673 Reported by Joel E. Denny.
4675 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
4676 Also work with M4 1.4.8.
4678 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
4680 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
4681 Jim Meyering.
4683 2006-10-25 Stepan Kasal <kasal@ucw.cz>
4685 * tests/tools.at (autom4te --force): New test, verifies that
4686 `--force' always rewrites the output file.
4688 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4690 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
4691 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
4693 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4695 * tools/trace.at (autoconf --trace: user macros): Test `$%'.

4699 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4700 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4701 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4702 reported by Nelson H. F. Beebe for Coreutils 6.4.
4704 * tests/tools.at (autoconf --trace: user macros): Remove test
4705 for tracing multiline macros, since m4 1.4.7a uses a different
4706 way to number lines. Problem reported by Ralf Wildenhues.
4708 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4710 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4711 /dev/null since the heuristics for interactive behaviour was
4712 fixed in CVS m4.
4714 * bin/autom4te.in: With --force, always refresh the output
4715 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4717 * bin/autoconf.as: Fix the verbose message at the end.
4719 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4736 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4737 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

4750 * NEWS: Likewise.
4752 2006-10-16 Eric Blake <ebb9@byu.net>
4754 * doc/autoconf.texi (Setting Output Variables): Fix typo.
4756 * bin/autoconf.as (version): Reword to match GNU Coding
4757 Standards.

4765 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4767 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4768 looking for special shell characters.
4769 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4770 macro defined by AS_VAR_PUSHDEF before passing it as a
4771 parameter.
4772 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
4773 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):
4774 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW, AC_CHECK_MEMBER):
4775 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL):
4776 (_AC_CHECK_HEADER_NEW, _AC_CHECK_HEADER_OLD, _AC_CHECK_HEADER_DIRENT):
4777 Likewise.

4782 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4784 (Imported from Automake.)
4785 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4786 which incorrectly sets the mode of an existing destination
4787 directory. In some cases the unpatched install-sh could do the
4788 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4789 system. We hope this is rare in practice, but it's clearly worth
4790 fixing. Problem reported by Alex Unleashed in
4791 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4792 Also, don't bother to check for -m bugs unless we're using -m;
4793 suggested by Stepan Kasal.
4795 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4797 Import this change from Automake:
4799 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
4800 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
4801 is enabled by default with gnu and gnits strictness.
4802 Report from Bruno Haible.
4804 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
4805 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
4806 gnu and gnits modes.
4808 Import this change from Config:
4810 2006-09-20 Ben Elliston <bje@gnu.org>
4811 * build-aux/config.sub (score, score-*): New.
4813 Import this change from Gnulib:
4815 2006-09-16 Karl Berry <karl@gnu.org>
4816 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
4817 to avoid sectioning errors.
4819 Import these changes from Texinfo:
4821 2006-10-04 Karl Berry <karl@gnu.org>
4822 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
4823 (\quoteexpand): rename to \rquoteexpand.
4824 (\codequoteleft): new def, to look for @set codequotebacktick.
4825 (\lquoteexpand, \quoteexpand): new defs.
4826 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
4827 (\code): must use new \...Char values, since now ` is active.
4829 2006-08-26 Karl Berry <karl@gnu.org>
4830 * build-aux/texinfo.tex (\textdegree): New command.
4832 2006-08-12 Karl Berry <karl@gnu.org>
4833 * build-aux/texinfo.tex (error \box0): smaller font.
4835 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4837 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
4839 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4841 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4842 added to the template can get mangled.
4844 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4846 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4847 include the default headers, and redefine obstack_chunk_alloc
4848 and obstack_chunk_free. Fixes false failure with glibc.
4850 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4852 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
4853 for backward compatibility with Libtool 1.5.22. Problem reported
4854 by Ralf Wildenhues.
4856 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4858 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
4859 AC_PROG_CC.

4862 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4864 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4865 the NonStop platform.
4866 * doc/autoconf.texi (Posix Variants): Likewise.
4867 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4869 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4870 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4871 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4872 Use a better substitute, by inspecting the output of "ls"
4873 rather than just using ":".
4874 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4875 rather than AS_EXECUTABLE_P, since we needn't worry about
4876 non-regular files here.
4878 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4879 due to configuration hassles with this. See Tonya Underwood's report
4880 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4884 Stepan Kasal <kasal@ucw.cz>
4886 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
4887 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4889 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4891 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4892 initialization which is not inherited through the environment
4893 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4894 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4896 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4898 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4899 problems with mkdir -p -m.
4901 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4903 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4904 comment about ac_cpp_err; it was incorrect, and anyway
4905 ac_cpp_err is being removed below.
4906 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4907 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4908 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4909 nobody uses it.
4910 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4911 with werror_flag and conftest.err and so forth. This is more
4912 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4913 and anyway the user shouldn't normally want to see this gorp logged.
4914 Problem reported by Ralf Wildenhues.
4915 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4916 empty, not 'no', since the rest of the code uses 'test -z'.
4918 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4920 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4921 Use a single call to AC_DO_TOKENS rather than multiple, for
4922 efficiency.
4923 (_AC_LINK_IFELSE): Test that resulting file is executable.
4924 Problem reported by mwoehlke in
4925 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4927 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4928 than creating a file to use with test -x; this is much faster.
4930 2006-10-02 Bruno Haible <bruno@clisp.org>
4932 * lib/autom4te.in (Automake-preselections): Add
4933 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4935 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4937 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4938 standard error, `experr' should be used, not `expout'.
4940 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4942 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4943 fseeko testing program twice; just use the earlier result.
4944 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4945 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4946 still doesn't let the program compile.
4947 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4948 failed.
4950 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4951 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4952 include it, without including anything else.
4953 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4954 expressions.
4955 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4957 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4959 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4960 `error.h', and include it, for a `error_at_line' prototype.
4961 Use a nonempty format string in the link test.
4962 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4963 for a declaration of wait3.
4965 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4967 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4968 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4969 can apply to constants too, and that it checks for macro defns.
4970 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4971 and simply cast the identifier to void. This handles structure
4972 values. Problem reported by Ralf Wildenhues.
4973 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4975 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4977 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
4978 structure, and function symbols.
4980 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4982 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
4983 member.

4996 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
4997 present.
4998 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add
4999 parentheses.

5007 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.
5008 Report by Olly Betts.

5028 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
5029 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
5030 --error-output, to avoid warnings with M4 2.0.
5032 2006-09-19 Stepan Kasal <kasal@ucw.cz>
5034 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
5035 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
5036 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
5038 2006-09-15 Stepan Kasal <kasal@ucw.cz>

5041 expansion of AC_CHECK_FUNCS.
5043 2006-09-14 Stepan Kasal <kasal@ucw.cz>
5045 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
5046 mistaken comment: the path has to be relative; do not use
5047 the path at runtime.
5049 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5051 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the
5052 argument to `--prefix' for sub-configure scripts.
5053 Pass `--silent' to sub-configure scripts.
5054 * tests/torture.at (Configuring subdirectories): Add tests
5055 for both changes.
5056 * doc/autoconf.texi (Setting Output Variables): Fix example to
5057 not show `--silent' being passed to a `configure' re-run.
5059 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
5061 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
5062 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
5063 for the existence of the directory at configure-time. That's
5064 too late, anyway. Problem reported by Stefan Seefeld.
5066 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
5067 7.1.4 /usr/bin/posix/sh described by Tim Rice in
5068 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
5070 2006-09-11 Stepan Kasal <kasal@ucw.cz>
5072 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
5073 works with GNU M4 1.4.3 again; make the normalized form
5074 match the current m4 message; fix the description.
5075 * test/tools.at (autom4te cache): Adapt to the change.
5077 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
5079 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
5080 to catch glibc bug 2821
5081 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
5083 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
5084 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
5085 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
5086 assume C89.
5088 2006-09-08 Stepan Kasal <kasal@ucw.cz>
5090 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

5104 by Dries Kimpe.
5106 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5108 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
5109 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
5110 accept files with extension `.f'. For consistency, also prefer
5111 xlf over f77.
5112 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
5113 from last patch.
5115 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

5128 before AC_PROG_FC, due to a bug in Autoconf.
5130 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
5132 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
5133 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
5134 except the first two arguments are reversed.
5135 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
5136 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
5137 caches nor outputs a diagnostic. Suggested by Bruno Haible.
5138 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
5139 equivalent to the old AC_COMPUTE_INT.
5140 (AC_COMPUTE_INT): No longer caches or reports. New signature.
5141 All uses changed to AC_CACHE_CHECK_INT.
5142 * tests/base.at (AC_CACHE_CHECK_INT): New test.
5143 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
5145 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
5147 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
5148 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
5149 programs should use their Gnulib counterparts.
5150 * doc/autoconf.texi (Particular Functions): Likewise.
5151 (Macro Names, testsuite Invocation): Replace uses of these
5152 obsolete macros with uses of non-obsolete macros.
5154 2006-08-29 Eric Blake <ebb9@byu.net>
5156 * configure.ac (AC_INIT): Bump to 2.60b.

5178 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
5180 Fix Lex library problem reported to us by Julio Garvia.
5181 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
5182 for the default, which the user can override.
5183 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
5184 deal with LEXLIB.
5185 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
5186 didn't work if some values were cached but not others. Test for
5187 broken lex libraries like native ia64-hp-hpux11.22; see
5188 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
5189 work around the problem by preferring an empty LEXLIB to -lfl or
5190 -ll. Let the user set LEXLIB='' to indicate no library needed.

5302 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
5303 Bill Northcott in
5304 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.

5318 -Wundef -Werror". Problem reported by David Fang in
5319 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
5320 * doc/autoconf.texi (Header Templates, Default Includes):

5335 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
5336 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
5337 this.
5339 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
5341 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
5342 problems with arg script text that doesn't end in newline, and
5343 with '-e a...'. Problems reported by Ralf Wildenhues.
5345 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
5347 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

5357 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
5358 --help' should mention that `--version' outputs configuration
5359 settings. Report by Bruno Haible.
5361 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
5363 Fix test suite failures reported by Pierre in
5364 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
5365 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
5366 the compiler created a file "b.out" when it didn't create anything
5367 at all.

5369 Discard stderr too, when invoking the test script.

5379 less skeptical about "volatile", after discussion with
5380 Bruno Haible on bug-gnulib.
5381 (Limitations of Usual Tools): Warn about sed stripping
5382 leading white space from text. From Bruno Haible.
5384 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5386 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5387 compiler complains about it, even if things works after the
5388 complaint. Problem reported by Peter O'Gorman.
5390 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5391 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5392 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5394 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5396 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

5400 * NEWS: Recommend M4 1.4.5.
5401 * README: Likewise.
5402 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
5403 * tests/tools.at (autom4te cache): Update wording of diagnostic
5404 to match M4 1.4.5.
5406 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5408 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5409 under AC_C_VOLATILE.
5410 (Volatile Objects): Be a little less skeptical about what
5411 "volatile" means. Derived from thoughts by Ben Pfaff in
5412 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5414 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5416 * doc/autoconf.texi: Fix some typos.
5418 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5420 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5421 more globally, since the 2006-06-30 patch didn't suffice. Problem
5422 reported by Keith Marshall. Also, don't bother with builddir2,
5423 since it shouldn't be needed any more.
5425 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5427 * doc/autoconf.texi (Generic compiler characteristics):
5428 Document AC_COMPUTE_INT. Fix wrong statements on Default
5429 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

5434 AC_COMPUTE_INT.
5436 * NEWS: Document change.
5438 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5440 * doc/autoconf.texi (Volatile Objects): New section.
5442 * NEWS: Document previous change.
5444 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5446 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5447 Require that long long int be at least 64 bits wide. C99 requires
5448 this and enough programs depend on it so we should check for it.
5449 Bruno Haible reports in
5450 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5451 that long long int is 32 bits wide with some nonstandard compilers.
5452 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5454 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5456 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5457 to a nonexistent file, so that we don't have to worry about
5458 a local site configuration that doesn't use /usr/local.
5459 Problem reported by Keith Marshall in
5460 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5462 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5464 * doc/autoconf.texi: Be more consistent about using @acronym with
5465 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5466 quite right (it talked about "OSF/Tru64", even though the
5467 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5468 and it even mentioned "OSF 4"!) and at this point there's little
5469 reason to talk about OSF any more, since it died in 1994.
5470 (Specific Compiler Characteristics): Simplify example of
5471 negative-size array.
5472 (File Descriptors): Reorder to make the text flow better.
5473 Remove joke about "appreciate the various levels"; I didn't get it.
5474 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5475 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5476 (File Descriptors, Limitations of Usual Tools):
5477 Tone down the advice against renaming or removing open files.
5478 (Limitations of Usual Tools): Add a new section, on 'rm'.
5480 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5482 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5483 -lXt in LIBS, idea from Karsten Hopp; this was due since
5484 this change:
5486 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5487 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5488 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5489 (which belong to Xt, not X itself). See Debian bug 327655.
5491 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5493 * configure.ac (AC_INIT): Bump to 2.60a.
5494 * NEWS: Update.

5502 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5504 * config/texinfo.tex: Sync from upstream.
5506 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5507 quadrigraph correctly in traces.
5509 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5510 Fix typos.
5512 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5513 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5514 not defined.
5515 * doc/autoconf.texi (Changed Directory Variables): New node,
5516 to document the whole `datarootdir' business a bit better.
5517 * NEWS: Update.
5518 * tests/torture.at (datarootdir workaround): Extend test.
5519 Prompted by report by Alexandre Julliard.
5521 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5523 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5524 when using default mode of IBM C 6 for AIX. Problem and two-line
5525 fix reported by Larry Jones.
5527 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5529 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5530 about literal '${datarootdir}' if a definition is found in the
5531 output file.
5533 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5535 * NEWS: Use "M4" rather than "m4" when appropriate.
5536 Problem reported by Eric Blake.
5537 * doc/autoconf.texi: Likewise.
5538 Use @acronym around BSD, GCC, and GNU when appropriate.
5539 (Why GNU M4): Renamed from "Why GNU m4".
5540 (Redefined M4 Macros): Mention that Posix
5541 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5542 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5543 to int.
5545 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5547 * bin/autom4te.in (handle_output): Do not forbid the empty
5548 pattern.
5549 * tests/tools.at (autoconf: the empty token): New test.
5551 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5553 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5554 calls, so that we do not care whether they are LIFO or FIFO;
5555 in the m4_wrap, do not check which diversion is the topmost
5556 one, just check that the stack is balanced at the end.
5557 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5558 base diversion forever--pop the previous diversion before
5559 opening the new one; consequently, remove the m4_wrap call.
5560 * lib/autotest/general.m4 (AT_INIT): Likewise.
5561 * tests/m4sugar.at: Do not use
5562 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5564 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5565 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5567 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5568 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5569 Rework example of m4wrap token-pasting trouble so that it doesn't
5570 care whether it's LIFO or FIFO.
5571 Fix some "contrary to"s that are awkward in English.
5573 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5575 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5576 to `yes' instead of `int$1_t' if the type is found, for more
5577 consistent configure output (where $1 is the number of bits).
5578 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5579 Suggested by Bruno Haible.
5581 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5582 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5583 with system headers. Report by Bruno Haible.
5585 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5587 * config/config.guess, config/config.sub: Sync from upstream.
5589 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5590 in order to avoid picking up an older installed frozen m4sh.m4f.
5591 Besides an outdated shell startup, this could have been created
5592 by an earlier M4 version with incompatible frozen file format.
5594 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5596 * README: Recommend m4 1.4.4 instead of 1.4.3..
5597 * doc/autoconf.texi: Likewise.
5598 (Special Chars in Names): Say that $(.FOO) is portable, as
5599 suggested by Stepan Kasal.
5600 (Installation Directory Variables, Build Directories):
5601 (Automatic Remaking, Subdirectories, Fortran Compiler):
5602 (Making testsuite Scripts, Defining Directories):
5603 Quote variable usages better.
5604 (Making testsuite Scripts): Add clean-local rule to makefile
5605 snippet, by Eric Blake.
5606 (Installation Directory Variables): Fix table item font.
5607 Reword slightly to clarify. Generalize advice about
5608 not using special characters to include all file-related
5609 vars, not just VPATH.
5610 (Special Chars in Variables): Warn about special characters in
5611 $(srcdir) too.
5612 (Assignments): Clarify default-value example as suggested by
5613 Ralf Wildenhues in
5614 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5615 (Special Shell Variables): Note leading ./ or ../, as suggested
5616 by Eric Blake.
5617 (Limitations of Builtins): Under cd, warn about CDPATH.
5618 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5619 Ralf Wildenhues.
5621 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5623 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5624 `@var', for texi2html.
5625 (Systemology): Some more word wrapping, for DVI output.
5626 (autom4te Invocation): The short option for `--melt' is `-M',
5627 not `-m'.
5629 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5631 * doc/autoconf.texi: More formatting and English tweaks,
5632 many suggested by Ralf Wildenhues.
5633 Reword to avoid "@code{...}'s" and the like, since it's ugly
5634 with Emacs info mode. discontents -> woes.
5635 Put a few "will"s back. time stamp -> timestamp.
5636 side-effect -> side effect.
5638 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5640 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5641 Warn about $@ not persisting. Problem reported by Julien Danjou in
5642 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5643 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5644 Mention other special chars, too.
5646 2006-06-14 Eric Blake <ebb9@byu.net>
5648 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5650 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5652 * doc/autoconf.texi: Some systematic minor improvements, as
5653 follows. Use "makefile" when talking about makefiles
5654 generally (which might be named "makefile" or "Makefile" or even
5655 "foo.mk"), "Makefile" when talking about a specific makefile
5656 called "Makefile". This unclutters the text from weird quotes
5657 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5658 values" rather than "@var{foo}s" and similar constructs containing
5659 "}s". Use "Make rules" rather than "Makefile rules". Minor
5660 English-language improvements. Change the prefix "sub-" to "sub"
5661 and "re-" to "re".
5662 Put blank lines around examples more consistently.
5663 Avoid "rather" and "very" as intensifiers.
5664 Avoid "will" as an auxiliary.
5665 (Limitations of Make): Split this node into....
5666 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5667 (Leading _ in Macro Names, Backslash-Newline-Newline):
5668 (Backslash-Newline Comments, Long Lines in Makefiles):
5669 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5670 (obj/ and Make, make -k Status, VPATH and Make):
5671 (VPATH and Double-colon, $< in Explicit Rules):
5672 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5673 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5674 New nodes, resulting from splitup of Limitations of Make.
5675 All cross-references changed. Raise the top node from
5676 a section to a chapter, and all subnodes accordingly.
5677 Redo the introductory wording to match the new organization.
5678 (Installation Directory Variables): Use an example that is
5679 closer to what Autoconf actually does. Mention that VPATH's
5680 value should not contain metacharacters or white space.
5681 (Fortran Compiler): Fix a VPATH bug in an example.
5682 (Leading _ in Macro Names): Mention that this problem is no longer
5683 of practical concern.
5684 (VPATH and Make): Reword the advice to make it clearer
5685 that Autoconf and Automake support VPATH in non-GNU make, but
5686 many packages have bugs in this area.
5687 ($< in Explicit Rules): Refer to Build Directories rather
5688 than using a (non-VPATH-safe) example.
5689 (Automatic Rule Rewriting): Mention the sort of disaster that
5690 can ensue with Solaris-style rule rewriting with VPATH.
5692 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5694 * doc/install.texi (Compilers and Options): Weaken the
5695 suggestion to use GNU make for VPATH builds.
5697 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5698 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5700 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5701 in regular expression.
5703 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5705 * doc/autoconf.texi (Installation Directory Variables):
5706 Drop extra @samp from `@table @samp' item.
5707 (Limitations of Usual Tools): Comment fix.
5708 Do not nest @samp just to point to other table items.
5709 (Writing testsuite.at) <AT_CHECK>: The second argument to
5710 `@dvar' is already @samp'ed.
5711 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5712 do not use @var in the second argument.
5714 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5716 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5717 $as_shell.exe too. Problem reported by Andreas Buening in
5718 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5720 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5722 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5723 `unused variable' compiler warning, for `-Wall -Werror'.
5724 Reported by Jaap Haitsma in
5725 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5727 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5729 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5730 case the compiler dumps core. Problem reported for
5731 OpenServer 5.0.7 by Tim Rice in
5732 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5733 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5734 Likewise.
5736 2006-06-06 Tim Rice <tim@multitalents.net>.
5738 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5739 "ERROR" only shows up in "make check" output if there is an
5740 error.
5742 2006-06-06 Eric Blake <ebb9@byu.net>
5744 * tests/tools.at (automatically allowed tokens): Fix typo.
5746 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5748 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5750 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5751 typically overflows on x86 CPUs, even though the C standard
5752 requires otherwise.
5754 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5756 * configure.ac (AC_INIT): Bump to 2.59e.
5757 * NEWS: Update.
5759 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5761 Version 2.59d.
5763 * config/texinfo.tex: Sync from upstream.
5765 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5766 seen, invoke libtoolize with `--ltdl' argument.
5767 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5768 * NEWS: Update.
5769 Suggested by Eric Blake.
5771 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5773 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5774 reported by Ralf Wildenhues.
5775 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5777 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5779 * THANKS: Update.
5781 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5783 * doc/autoconf.texi: Modernize some of the references to Solaris.
5785 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5787 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5788 message issued by AC_REQUIRE.
5789 * tests/m4sugar.at: Check m4_require's error message.
5790 * tests/base.at: Check AC_REQUIRE's error message.
5791 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5792 to...
5793 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5794 AT_CHECK_M4.
5795 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5796 `expout' as the last parameter.
5797 * tests/tools.at: Adapt to the above change.
5799 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5801 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5802 information about race-free implementations of mkdir.
5804 2006-06-04 Eric Blake <ebb9@byu.net>
5806 * bin/autoreconf.in (help): Document M4 environment variable.
5807 * bin/autoconf.as (Usage): Likewise.
5808 * bin/autom4te.in (help): Likewise.
5809 * doc/autoconf.texi (autom4te Invocation): Likewise.
5811 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5813 * NEWS: GNU make now recommended for VPATH builds.
5814 Mention that some macros are now documented to be obsolescent.
5815 * doc/autoconf.texi:
5816 Prefer "current" to "modern" to describe
5817 currently-used (albeit perhaps old-fashioned) hosts.
5818 Mention which ancient features no longer need to be worried about.
5819 setgid -> set-group-ID
5820 setuid -> set-user-ID (these are the Posix terms)
5821 Fix some misuses of "only".
5822 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5823 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5824 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5825 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5826 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5827 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5828 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5829 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5830 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5831 Mention that these macros are obsolescent.
5832 (Installation Directory Variables): shall -> should
5833 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5834 Mention that it's now safe to use 3 and 4.
5835 (Limitations of Usual Tools): cp -r is now specified by Posix.
5836 Omit longwinded and obsolescent discussion of cp -f.
5837 Modernize discussion of expr, ls.
5838 (Limitations of Make): Modernize discussion of VPATH builds.
5839 Mention $? as a workaround in some cases.
5840 * doc/install.texi (Basic Installation):
5841 Mention "./configure; make; make install" first. Be more
5842 specific about why this file is generic. Remove unnecessary
5843 parens. Remove misleading "only". Remove obsolete advice
5844 about csh. Don't say "configure" takes awhile; say it
5845 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5846 and CC=c99 rather than CC=c89, as these are blessed by current
5847 Posix. Recommend GNU make if doing a VPATH build.
5849 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5851 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5852 examples involving shell prompts.
5854 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5855 and Paul Eggert <eggert@cs.ucla.edu>
5857 * doc/autoconf.texi (Here-Documents): Add details about the
5858 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5859 use "here-documents" instead of "here documents".
5861 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5863 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5865 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5867 * doc/autoconf.texi (File System Conventions): Warn about ":"
5868 anywhere in directory names.
5870 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5872 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5873 about quoting the case statement, just in case.
5874 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5875 was fixed in ksh93g; reported by Ralf Wildenhues.
5877 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5879 * doc/autoconf.texi (System Services): Do not document
5880 overriding EXEEXT via ac_cv_exeext=ext.
5881 (Particular Programs) <AC_PROG_MKDIR_P>:
5882 Document that ${MKDIR_P} understands --.
5883 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5884 comment.
5886 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5888 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5889 argument with leading hyphen. Problem reported by Paul Eggert.
5891 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5893 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5894 about quoting ac_try: quote all of it, if any of it seems suspicious.
5895 This means we don't have to worry about ${ or sed any more.
5896 Also, double-quote the case statement, to work around misuses via
5897 underquoting as reported by Ralf Wildenhues in
5898 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5899 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5900 undocumented and dangerous macro.
5901 Problem reported by Ralf Wildenhues in
5902 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5904 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5906 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5907 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5908 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5910 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5912 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5913 since evidently some packages rely on the old, broken behavior.
5914 Problem reported by Ralf Wildenhues in
5915 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5916 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5917 pre-2006-05-26 definitions, but leave in the comments that
5918 these macros are dangerous and should not be used.
5919 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5920 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5921 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5922 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5923 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5925 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5927 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5928 the use of 'tr', since this is our only use of 'tr'.
5930 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5931 and Paul Eggert <eggert@cs.ucla.edu>
5933 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5934 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5936 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5938 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5939 the output file in the `${datarootdir}' test.
5941 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5942 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5944 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5945 mention of `datarootdir' in the input file(s), but literal
5946 `${datarootdir}' in the output file, and we haven't warned yet,
5947 then warn as well: the user may have (erroneously) used
5948 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5949 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5950 * tests/torture.at (datarootdir workaround): Extend this test.
5951 * NEWS: Update.
5953 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5954 and Paul Eggert <eggert@cs.ucla.edu>
5956 * doc/autoconf.texi (autoheader Invocation): The first argument to
5957 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5958 alternatives and clear up the language a bit.
5960 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5962 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5963 ac_config_guess, ac_config_sub, ac_configure.
5964 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5965 Fix typo that prevented an unnecessary space from being removed.
5966 Problems reported by Ralf Wildenhues in:
5967 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5969 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5971 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5972 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5973 Don't use the term "thread-safe" to talk about mkdir race
5974 conditions, since the problem is more a process than a thread
5975 issue. Problem reported by Stepan Kasal in:
5976 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5977 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5978 the test for 'install' more closely. Look at MKDIR_P first.
5979 Look in the PATH, and at /opt/sfw/bin.
5980 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5981 Don't bother to try mkdir -p, since we already check mkdir --version;
5982 just look at the version number. (There's no easy way to check
5983 for race-free implementations.)
5984 * tests/tools.at (autoconf: subdirectories): Adjust to above
5985 changes, since MKDIR_P now might end in "/mkdir -p".
5987 * doc/autoconf.texi (autoheader Invocation): Mention that the
5988 first arg of AC_DEFINE_UNQUOTED must be a literal.
5989 Problem reported by Ben Pfaff in
5990 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5992 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5993 * doc/autoconf.texi (Special Chars in Variables): New section.
5994 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5995 (Installation Directory Variables): Quote $(datadir) better.
5996 (Limitations of Builtins): Describe some of eval's trickiness.
5998 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5999 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
6000 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
6001 in front of every arg, not just trailing args. Quote apostrophes.
6002 (_AC_EVAL_ECHO): New macro.
6003 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
6004 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
6005 removed.
6006 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
6007 exposed by quoting of eval argument. Put the command on line line
6008 so it logs better.
6009 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
6010 (_AC_PATH_X, AC_PATH_X): Quote more safely.
6011 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
6012 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
6013 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
6014 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
6015 Use eval more safely.
6016 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
6017 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
6018 to be replaced.
6019 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
6020 lines, exposed by quoting of eval argument.
6022 2006-05-26 Stepan Kasal <kasal@ucw.cz>
6023 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6025 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
6026 initialization of `ac_cv_exeext', do not override it if it was
6027 already set, unless it was set to `no', for compatibility with
6028 Autoconf-2.13, and comment this.
6029 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
6030 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
6031 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
6032 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
6033 Document that this test may be overridden by setting
6034 `ac_cv_exeext'.
6036 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6038 Revert these two patches:
6040 2006-04-06 Eric Blake <ebb9@byu.net>
6041 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6042 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6043 2006-04-01.
6045 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6046 Clean up _AC_COMPILER_EXEEXT* macros.
6047 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6048 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6049 ac_file to the name of the default output file and call
6050 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6051 initial `rm' of the candidate files...
6052 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6053 the same list in subsequent `rm' calls, and for the temporary
6054 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6055 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6056 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6057 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6058 no longer needed) by libtool. Make it a cache check.
6059 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6060 copied here by mistake.
6061 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6062 _AC_COMPILER_EXEEXT.
6063 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6064 _AC_COMPILER_OBJEXT directly.
6065 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6067 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6069 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6070 Fix description of how the buggy `sed' works.
6072 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6074 Sync from Automake:
6076 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6077 ENOLCK. Only mention `make -j' when applicable. Only raise
6078 fatal errors when `make -j' is involved. Improve error message.
6080 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6082 * doc/autoconf.texi (Here-Documents): We now know more about
6083 the variable expansion in here documents bug.
6084 Thanks to Tim Rice and Stepan Kasal.
6086 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6087 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6089 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6091 * tests/autotest.at (Multiline command from M4 expansion):
6092 No failure to be expected if the shell quotes newlines in
6093 commands in the `set -x' output. Report by Tim Rice.
6094 * THANKS: Update.
6096 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6098 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6099 expansion in the here-documents used by config.status, as that
6100 runs afoul of the Korn shell version M-12/28/93d bug described in
6101 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6102 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6103 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6105 2006-05-23 Jim Meyering <jim@meyering.net>
6107 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6108 Fix typo introduced with 2006-04-02 change. It reversed the sense
6109 of the test.
6111 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6113 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6114 ac_dB slightly, to save bytes in the script.
6115 Max out at 50 lines, rather than 96; this is more likely
6116 (though not guaranteed) to avoid obscure 'sed' failures.
6118 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6120 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6121 `tr -d -' as bad option argument. Work around this by deleting
6122 an unrelated character.
6123 Report by Tim Rice <tim@multitalents.net>.
6125 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6126 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6127 Stepan Kasal <kasal@ucw.cz>
6129 * doc/autoconf.texi (Particular Programs): Do not promise that
6130 we always prefer the GNU version of the program, and that we
6131 search according to PATH; both rules can have exceptions.
6132 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6133 AC_PROG_SED. Move descriptions of limitations
6134 to the Limitations of Usual Tools section.
6135 (Limitations of Usual Tools) <sed>: Mention script length
6136 limitations with Solaris /usr/ucb/sed.
6137 <grep>: Fix wording for empty alternative. Mention that -c and
6138 -l should not be combined, and that -E and -F should not be
6139 combined.
6141 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6142 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6144 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6145 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6147 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6149 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6150 AC_DEFINE is now passed to m4_pattern_allow.
6151 * NEWS: Mention that; likewise for AC_SUBST.
6152 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6153 the parameter to m4_pattern_allow.
6154 * tests/tools.at: Add a check for that.
6156 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6158 * lib/autoconf/status.m4: Fix typos.
6160 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6162 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6163 only the files that this macro generates.
6165 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6167 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6168 the HP-UX sed limitation of 99 commands, labels do not count.
6169 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6170 in the comment.
6171 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6173 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6175 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6176 Import the following fix from coreutils:
6178 2006-01-13 Jim Meyering <jim@meyering.net>
6180 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6181 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6182 not double-quote uses of that variable, to accommodate the rare
6183 case in which getmntent is available in none of the libraries
6184 checked. This happens at least on FreeBSD 5.0.
6186 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6188 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6189 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6190 some other programs unwisely rely on these undocumented vars.
6191 But put in warning comments about them.
6192 Problem reported by Ralf Wildenhues in
6193 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6194 * NEWS: Document that these variables are intended to go away.
6196 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6198 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6199 and set the language to C++ (analogous to the equivalent Fortran
6200 tests).
6202 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6203 * doc/autoconf.texi (C++ Compiler): Document it.
6204 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6205 * NEWS: Update.
6207 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6209 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6210 that caused config.status to generate 100-command sed scripts; the
6211 portable limit is 99.
6213 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6215 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6216 variable `ac_d' instead of `d' to avoid infringing namespace.
6217 Report by Ralf Menzel.
6219 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6221 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6222 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6223 * tests/tools.at (autoconf: subdirectories): New test, taken from
6224 the corresponding problem report by Ralf Wildenhues in:
6225 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6227 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6228 Quote some uses of shell variables if they might suffer unexpected
6229 globbing. This doesn't fix all instances of quoting problems that
6230 I found, just the easy ones that look safe.
6231 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6232 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6233 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6234 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6235 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6236 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6237 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6238 Likewise.
6239 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6240 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6242 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6244 * bin/autoreconf.in ($help): Reword according to the manual.
6245 Suggested by Olly Betts.
6247 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6248 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6250 * bin/autoreconf.in: Pass the directory argument to
6251 `require_configure_ac'. Fix comment.
6252 * tests/torture.at (Configuring subdirectories): Expose this.
6253 Reported by Olly Betts.
6255 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6257 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6258 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6259 Automake as follows:
6261 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6262 `$configure_in' instead of `configure.in', to preserve
6263 directory component.
6265 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6267 * config/config.guess, config/config.sub, config/texinfo.tex,
6268 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6270 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6272 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6273 test for C99 conformance; (bool) 0.5 is an integer constant
6274 expression, but (bool) -0.5 is not. Problem reported by Fedor
6275 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6277 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6279 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6280 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6281 Warn about obsolete install-sh files. Remove stray sentence
6282 fragment and fix cross reference.
6283 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6284 install -d; this undoes the 2006-05-10 change.
6285 (MKDIR_P): Mark with AN_MAKEVAR.
6286 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6287 that we don't require $INSTALL to be thread-safe. Move comments
6288 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6289 of AC_PROG_INSTALL. Output a message saying that we're checking
6290 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6291 MKDIR_P instead of AC_SUBST.
6292 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6293 Special magic for MKDIR_P, too.
6294 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6295 a dnl.
6296 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6298 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6300 Sync from Automake, as follows:
6302 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6303 * config/install-sh: Initialize IFS, so field splitting isn't
6304 turned off later.
6305 * config/mkinstalldirs: Likewise.
6306 * config/missing: Remove superfluous quotes. Replace all uses of
6307 `[' by `test', for consistency, and for..
6308 * config/missing (sed_minuso, sed_output): New variables.
6309 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6310 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6311 Fixes `missing' to detect `--output' for help2man. Fixes
6312 PR automake/483. Report by Dennis J. Linse.
6313 (autom4te): Document in `missing --help'.
6315 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6317 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6318 * config/install-sh: Don't use 'path' to talk about file names,
6319 as per GNU coding standards. Close a race condition reported by Ralf
6320 Wildenhues and Stepan Kasal. There is still a race condition
6321 on hosts that predate Posix 1003.1-1992, but we can't help this.
6322 Don't mishandle weird characters like space on pre-Posix hosts.
6323 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6324 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6325 AC_PROG_MKDIR_P from AS_MKDIR_P.
6326 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6327 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6328 earlier editions are not (including Automake 1.8.3).
6329 Do not suggest mkinstalldirs for thread-safety.
6330 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6331 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6332 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6333 presence of special characters and race conditions.
6334 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6335 in Autoconf's name space.
6337 2006-05-10 Bruno Haible <bruno@clisp.org>
6338 and Paul Eggert <eggert@cs.ucla.edu>
6340 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6341 from Automake with minor changes.
6342 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6344 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6346 * config/install-sh: Update to Automake CVS version, as follows:
6347 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6348 * lib/install-sh: Simplify the expr implementation of dirname.
6349 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6350 * lib/install-sh: Handle --, and diagnose unknown options.
6352 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6354 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6355 `./autom4te' to create `./testsuite', since the `all' target
6356 will ensure its presence, but `installcheck' should not create
6357 the uninstalled wrappers.
6359 * tests/torture.at (Unusual Automake input files): Skip if we
6360 detect automake < 1.8.
6362 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6364 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6365 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6366 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6367 * NEWS: Update.
6369 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6371 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6372 munge (multiple) white space and other oddities.
6373 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6374 single quotes in variable assignment.
6375 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6376 and similar failures by adding multiple spaces, tabs, and other
6377 special characters.
6378 Report and different test suggested by Francesco Romani
6379 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6381 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6382 single quotes, we only need to search for single quotes; this
6383 both simplifies the search pattern, and makes us less
6384 susceptible to `echo' variations for arguments not containing
6385 single quotes.
6386 (_AC_ARG_VAR_VALIDATE): Likewise.
6388 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6390 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6391 `$*' and IFS concatenation issue with traditional shells and
6392 bash-2.04. Report by Seanster@Seanster.com.
6394 2006-05-03 Bruno Haible <bruno@clisp.org>
6396 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6397 precisely which Mac OS X versions have the od problem.
6399 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6401 * doc/autoconf.texi: Use @option systematically.
6403 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6404 and Bruno Haible <bruno@clisp.org>
6406 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6407 about 'od'.
6408 (Integer Overflow): Mention the special case of integer division
6409 overflow.
6411 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6413 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6414 traditional shells like the Solaris one that do not use the
6415 first IFS character for assembling `$*'.
6416 Prompted by a related report from autoconf_bug@nro.ca.
6418 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6419 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6421 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6422 Mention more problems with the -e option.
6424 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6426 * NEWS: Typo.
6427 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6429 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6430 in URLs to improve DVI formatted output (requires texinfo 4.6).
6431 (System Services, Systemology, Shellology): Likewise.
6432 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6433 output.
6435 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6436 continuous text.
6437 (Runtime): Fix macro argument names to match description:
6438 `action-if-found' -> `action-if-true' and similarly.
6439 (Obsolete Macros): Likewise.
6440 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6441 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6442 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6444 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6446 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6448 * ChangeLog: Typo.
6449 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6450 DVI output.
6452 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6461 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
6462 (Integer Overflow, Null Pointers, Buffer Overruns):
6463 (Floating Point Portability, Exiting Portably): New sections.
6464 (Writing Test Programs): Fix some langauge. Recommend exiting
6465 with status 1, not merely nonzero. Clarify exit declaration.
6466 (Run Time): Move C exit status stuff to new Exiting Portably section.
6467 (Systemology): Mention Posix and levenez. Update v7 reference.
6468 (Portable Shell): Mention the Posix shell.
6470 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6472 * bin/autoconf.as (me): Replace by as_me.
6474 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6476 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6477 since as_me isn't set yet.
6479 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6481 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6482 a few minor bugs in this area.
6484 * doc/autoconf.texi (Programming in M4sh): Comment out the
6485 documentation of AS_BASENAME, for now.
6486 (Shell Substitutions): Do not use AS_DIRNAME in an example.

6501 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6502 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6503 (AS_DIRNAME): Use "dirname --".
6505 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6507 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6508 of "run time" and "run-time" changed to "runtime", for consistency.
6509 * lib/autoconf/fortran.m4: Likewise (in comment).
6510 * lib/autoconf/functions.m4: Likewise.
6511 * lib/autoconf/general.m4: Likewise.
6512 * lib/autoconf/headers.m4: Likewise.
6514 * doc/autoconf.texi (Run Time): Document the exit status situation
6515 with more accuracy and detail.
6517 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6519 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6520 Archive is not officially `GNU' any more. Update URL.
6521 (Defining Directories): Likewise
6522 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6524 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6526 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6527 newline from the `trap' code to finish `config.log'; the NetBSD
6528 /bin/sh resets the exit status after an empty command, as
6529 documented in doc/autoconf.texi.
6530 Reported by Dalibor Topic <robilad@kaffe.org>.
6532 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6534 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6535 Suggested by Bruno Haible.
6537 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6539 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6540 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6541 Instead, just list the shells that we know work.
6542 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6543 changed. Be more cautious about the _cv_ variable.
6544 * tests/tools.at (Syntax of the shell scripts): Check the
6545 _cv_ variable once, at first, to avoid an internal autoconf error
6546 when sh -n does not work.
6548 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6550 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6552 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6554 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6555 use ">&-" since we're only 99.999% sure that this is portable,
6556 and since the MinGW bug is fixed in a different way.
6557 * lib/autotest/general.m4 (AT_INIT): Likewise.
6559 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6561 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6562 before opening config.log, to avoid hitting a bug on MinGW.
6564 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6566 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6567 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6568 This works around a MinGW bug reported by Eric Paire.
6569 Make sure that all writes to the log file append to it,
6570 rather than possibly losing data.
6571 * lib/autotest/general.m4 (AT_INIT): Likewise.
6573 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6575 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6576 description.
6578 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6580 * NEWS: Update.
6582 * configure.ac (AC_INIT): Bump to 2.59d.
6584 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6586 Version 2.59c.
6588 * Makefile.maint (news-date-check): Do not require a leading `*'
6589 before the release date in NEWS.
6591 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6592 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6594 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6595 the instantiated file do not contain the string 'datarootdir'
6596 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6597 @mandir@, replace the reference '${datarootdir}' by the value.
6598 * tests/torture.at (datarootdir workaround): New test.
6599 * NEWS: Advertise this temporary fixup.
6600 Based on a patch by Bruno Haible, reported and analyzed by
6601 Paul Eggert and Noah Misch.
6603 2006-04-12 Eric Blake <ebb9@byu.net>
6605 * tests/autotest.at (Debugging a failed test): Fix comment.
6607 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6609 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6610 all the changes since 2006-04-07.
6612 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6614 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6615 succeeded, but `ln -s file dir' failed, take care to remove the
6616 leftover target before the next test, to prevent its spurious
6617 failure; also make sure `ln file dir' works before selecting it.
6618 Thanks to Keith Marshall for pointing this out.
6619 * THANKS: Update.
6621 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6622 assignments in `at_debug_args', so that we put them correctly
6623 in the `run' script.
6624 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6625 Reported by Eric Blake.
6627 2006-04-11 Eric Blake <ebb9@byu.net>
6629 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6630 top-level tests after micro-suite has been run. Used in...
6631 (Debugging a successful test, Debugging script and environment),
6632 (Debugging a failed test): ...these new tests. The first of these
6633 is fixed by...
6634 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6635 macro, split out from...
6636 (AT_INIT): ...here, so that using -d also generates a run script.
6637 Document that -d inhibits top-level logging.
6638 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6639 inhibits top-level logging; debug scripts are created.
6641 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6642 check.
6643 * tests/autotest.at (Empty test, Empty check): New test to check it.
6645 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6646 from gcc.
6648 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6650 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6651 the files if a problem appears. Make the empty *.at files
6652 read-only, too. Proposed by Ralf Wildenhues.
6654 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6656 * config/Makefile.am: Add comment to force updated Makefile.in.
6658 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6659 space only patch to this file, this patch causes the Makefile.in
6660 files that include freeze.mk to be updated, and thus have a
6661 newer time stamp again, which in turn makes a pristine CVS
6662 checkout have correct time stamps.
6664 * Makefile.maint (cvs-sv): New macro, to be used..
6665 (config.guess-url_prefix, config.sub-url_prefix)
6666 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6667 point to CVS text checkout of Gnulib files.
6668 (copyright-check): Bump current year.
6669 (announcement): Do not hard-wire `./announce-gen'.
6670 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6671 correctly.
6672 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6673 `chmod +x'.
6674 (wget_files): Update config.guess, config.sub, texinfo.tex by
6675 `wget-update', now that their URLs work again.
6677 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6679 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6680 Problem noted by Paul D. Smith.
6682 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6684 * doc/autoconf.texi: Remove unused words from word list.
6685 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6686 .x-sc_trailing_space: New files.
6688 * doc/standards.texi: Sync from gnulib.
6690 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6691 `LIBOBJDIR' as experimental.
6693 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6694 with a target directory; it's internally implemented as `cp'
6695 anyway, but since Autoconf advertises the possibility to use
6696 a target directory when LN_S is `ln -s', we need to find out.
6697 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6698 analyzed by Keith Marshall <keith.marshall@total.com>.
6700 * THANKS: Update.
6702 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6704 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6705 confdefs.h as-is. In general, if it has backslash-newline or the
6706 like, then it doesn't work either to sort or to remove empty
6707 lines.
6709 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6711 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6713 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6715 * lib/autom4te.in (Automake-preselections): Preselect
6716 _AM_SUBST_NOTMAKE.
6718 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6720 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6721 apostrophe within a single-quoted string, as this is the usual
6722 tradition and is easier to read than '"'"'. Don't rely on the
6723 shell treating "$/" like '$/'. Use a more-consistent indenting
6724 style for the trap.
6726 2006-04-09 Eric Blake <ebb9@byu.net>
6728 * tests/autotest.at (Backquote command substitution),
6729 (Multiline backquote command substitution): Remove mistaken
6730 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6731 applied...
6732 (Parenthetical command substitution, Multiline parenthetical
6733 command substitution): here.
6735 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6737 Import macros from gnulib (often changing their name).
6739 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6740 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
6741 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

6744 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6745 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
6746 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
6747 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
6748 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
6749 The manual mentions Gnulib more prominently.
6750 * doc/autoconf.texi (Gnulib): New node.
6751 (Pointers): Add Gnulib URL.
6752 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6753 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6754 Gnulib section.
6755 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6756 suggest a #define rather than a typedef for _Bool, and mention
6757 Gnulib rather than trying to substitute stdbool code.
6758 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6759 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6760 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6761 AC_STRUCT_DIRENT_D_TYPE.
6762 (Particular Types): Mention stdint.h and inttypes.h as standard
6763 headers too.
6764 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6765 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6766 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6767 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6768 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6769 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6770 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6771 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6772 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6773 (Coding Style). Don't mention m4_expand_once.
6774 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6775 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6776 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6777 (AC_CHECK_FUNCS): Use it.
6778 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
6779 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
6780 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
6781 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
6782 (AC_HEADER_ASSERT): New macro.
6783 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6784 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6785 Catch a bug in an HP-UX C compiler.
6786 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6787 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6788 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
6789 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
6790 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
6791 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6792 New macros.
6794 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6795 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6797 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6799 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6800 of the warning introduced by the 2001-08-28 change.
6802 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6803 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6805 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6806 variables shall be overriden by the cache.
6807 * tests/torture.at (AC_ARG_VAR): Test also with a first value
6808 that contains braces.
6810 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6812 Revert the patch from 2006-04-01 and only improve
6813 _AS_DETECT_BETTER_SHELL:
6815 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6816 skip nonexistent directories.
6817 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6818 only shell candidates which exist.
6819 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6820 * lib/autotest/general.m4 (AT_INIT): No need to give three
6821 parameters to _AS_PATH_WALK.
6823 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6824 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6826 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6827 distinguish m4sugar macros.
6828 * tests/tools.at (autoupdating with aclocal and m4_include):
6829 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6830 test case by Noah Misch <noah@cs.caltech.edu>.
6832 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6834 Revert my change from 2006-03-17, in other words:
6835 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6836 and DUALCASE=1.
6837 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6838 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6839 it is set.
6841 2006-04-07 Eric Blake <ebb9@byu.net>
6843 * doc/autoconf.texi (Programming in M4sh): Document that
6844 AS_MKDIR_P exits the script on failure.
6845 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6847 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6849 * config/elisp-comp, config/install-sh, config/mdate-sh,
6850 config/missing, config/mkinstalldirs: Sync from Automake.
6852 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6853 from Automake.
6855 * doc/make-stds.texi: Sync from gnulib.
6857 2006-04-06 Eric Blake <ebb9@byu.net>
6859 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6860 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6861 2006-04-01.
6863 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6864 Eric Blake <ebb9@byu.net>,
6865 Paul Eggert <eggert@cs.ucla.edu>,
6866 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6868 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6869 whether `set' quotes correctly: redirect stderr of the tested
6870 `set', and use a subshell, for Ultrix; use `sed' instead of
6871 `grep' for zsh `set' which may write binary output; match only
6872 at the beginning of a line, to avoid false positives.
6873 In order to avoid false positives by unrelated variables with
6874 multiline content, put the dump algorithm in a subshell and
6875 unset all variables containing newlines (except some which are
6876 special to the shell). Warn about cache variables that are
6877 unset.
6879 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6881 * config/config.guess, config/config.sub, config/texinfo.tex:
6882 Sync from upstream.
6884 * tests/mktests.sh: Reword comments.
6886 * tests/mktests.sh: Only skip internal macros starting with
6887 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6888 Update exclusion lists for the test suite to this end:
6889 (AC_ARG_VAR): Do test this now.
6890 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6891 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6892 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6893 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6895 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6896 shell issue with double-quoted command substitutions of native
6897 commands.
6898 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6899 Marshall.
6901 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
6902 no file matches the glob, discard the warning, set `nullglob'.
6903 (syntax-check): Likewise.
6904 (sc_cast_of_x_alloc_return_value): Likewise.
6905 (sc_cast_of_alloca_return_value, sc_error_exit_success)
6906 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
6907 (m4-check): Likewise.
6908 (sc_system_h_headers): Do not print rule on execution.
6909 (sc_tight_scope): Do not fail for non-existing `src' directory.
6910 (sc_changelog): Skip the Copyright footer.
6911 * lib/autoconf/lang.m4: Remove trailing space.
6913 * lib/autoconf/status.m4: More replacements to
6914 <tab><space> where this makes sense.
6916 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6918 * tests/Makefile.am (maintainer-check-posix):
6919 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6921 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6922 ac_config_<foo>s again, sometimes normalized, sometimes not.
6923 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6924 (AC_CONFIG_COMMANDS): Do not do so here.
6925 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6926 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6927 2005-07-25 rewrite. Noticed by Noah Misch.
6929 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6930 _AC_PRESERVE_HELP_ORDER, ...
6931 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
6933 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
6934 inside m4_expand_once; it is redundant.
6936 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
6937 for --help from Cygnus `configure.'
6939 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
6941 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
6942 on a patch proposed by Ralf Wildenhues.
6944 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
6946 * lib/autoconf/status.m4: Replace <space>''<tab> with

6957 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6959 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
6960 lib/autoconf/specific.m4, lib/autoconf/status.m4,
6961 lib/autoconf/types.m4, lib/autotest/general.m4,
6962 tests/mktests.sh, tests/torture.at: White space cleanup:

6965 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
6967 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.

6995 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
6996 (exclude_list): Exclude empty macros.

7080 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
7081 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
7082 ac_file to the name of the default output file and call
7083 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7084 initial `rm' of the candidate files...
7085 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7086 the same list in subsequent `rm' calls, and for the temporary
7087 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
7088 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
7089 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7090 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7091 no longer needed) by libtool. Make it a cache check.
7092 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
7093 copied here by mistake.
7094 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
7095 _AC_COMPILER_EXEEXT.
7096 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

7132 subordinate tools.
7133 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
7134 * doc/autoconf.texi (autoreconf Invocation): Document it.
7136 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

7168 2006-04-01 Stepan Kasal <kasal@ucw.cz>
7170 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
7171 switch all of them on and of when necessary. Fixes the bug when
7172 m4sugar macros (e.g., m4_define) were expanded after the first
7173 automatic update (e.g., after AC_PREREQ or AC_INIT).
7175 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

7223 checked for existence, so we don't barf over a nonexisting
7224 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
7226 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7291 (AC_CHECK_SIZEOF, AC_CHECK_SIZEOF struct): Use it.

7350 keywords, keywords taken from AT_SETUP arguments, and numeric

7370 trying to execute the command `no'.
7372 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not

7866 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7867 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7868 the inner workings of AC_LANG_FUNC_LINK_TRY.
7869 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7870 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7871 by the function rather than ignoring it.
7872 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7873 comparing its address. Intel's interprocedural optimization was
7874 outsmarting the old heuristic. Problem reported by
7875 Mikulas Patocka.
7877 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7879 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7881 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7883 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
7884 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
7886 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7888 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7889 before removing it (chmod -R u+rwx); there are three instances of this.
7891 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7892 Stepan Kasal <kasal@ucw.cz>
7894 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7895 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7896 make its content writable before removing it. Remove an errorneous
7897 comment from the end, where the logs of the failed tests are copied
7898 to the main log file.
7900 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7902 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7903 in case the computer is too quick. Double quote the configure.ac
7904 snippets.
7906 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7907 problems if the testsuite were running too fast.
7909 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7911 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7912 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7913 (which belong to Xt, not X itself). See Debian bug 327655.
7914 * NEWS: Mention this.
7916 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7918 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7920 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7922 * config/move-if-change: Don't output "$2 is unchanged";
7923 suggested by Ben Elliston. Handle weird characters correctly.
7925 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7927 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7928 calls, so that the final expansion of this macro is shorter.
7929 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7930 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7931 the cleanup there. Use AS_VAR_* macros, to be more general.
7932 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7934 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7936 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7938 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7940 * doc/autoconf.texi (Configuration Headers): Add an index entry
7941 for AH_HEADER.
7943 2005-08-26 Pavel Roskin <proski@gnu.org>
7945 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7946 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7947 running xmkmf.
7949 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7951 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7952 The previous patch didn't work, so try a better one.
7954 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7956 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7957 in the example. Reported by Bruno Haible.
7958 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7959 "if $undefined_var;" succeeds with my shell.
7961 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7962 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7963 but change the m4_divert_text to m4_divert_once.
7965 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7967 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7968 Work around bug in Solaris /usr/xpg4/bin/awk.
7969 The bug is present in at least Solaris 8 through 10.
7971 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7973 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7974 some evil values and relying on the fact that $* concatenates the
7975 parameters by the first character from IFS.
7977 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7978 Stepan Kasal <kasal@ucw.cz>
7980 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7981 first header appears, define AH_HEADER.
7982 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7983 Update limitations about when to call AC_CONFIG_HEADERS.
7984 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7985 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7986 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7987 ``Configuration Actions''; fix their index entries.
7989 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7990 options correctly. Process N-M as M-N if M is smaller than N.
7991 Process ranges correctly so that N-N will run only N.
7992 Sort and uniquify the tests that will be run. If there is more
7993 than one test, reinsert the banners for the tests.
7994 * tests/autotest.at (Keywords): Unmark XFAIL.
7996 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7998 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7999 before passing the macro name to AH_TEMPLATE.
8001 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
8002 now opens log after option processing; in particular, --version
8003 and --help do not touch config.log.
8005 * Makefile.maint: Revert the change from 2005-08-12.
8007 2005-08-22 Stepan Kasal <kasal@ucw.cz>
8009 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
8010 common code to...
8011 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
8013 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8015 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
8016 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
8017 Language cleanup.
8019 * doc/autoconf.texi (Defining Symbols, Changed Results):
8020 Prepend to LIBS, not append, in examples.
8022 2005-08-16 Stepan Kasal <kasal@ucw.cz>
8024 When building in place, set srcdir="."; suggested by Tim Van Holder.
8026 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
8027 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
8028 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
8029 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
8030 does not mean "no --srcdir option".
8032 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8034 * tests/autoscan.at (autoscan): New file.
8035 * tests/suite.at: Use it.
8036 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
8037 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
8039 * tests/autotest.at (Keywords): Test keywords combinations.
8041 2005-08-12 Stepan Kasal <kasal@ucw.cz>
8043 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8044 add "2>&1"; gzip 1.2.4 prints help on stderr.
8046 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8048 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8049 was pushdef'ed twice while popped only once. Push it only once.
8050 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8052 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8054 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
8055 prefixed by mere "===", not "configure: === ".
8057 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
8059 * Makefile.maint: Update from Bison.
8061 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8062 "<tab>" in comment, so that the point is understandable.
8064 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8066 Rewrite substantial part of lib/autoconf/status.m4.
8067 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8068 and CONFIG_COMMANDS are not processed in four separate loops.
8069 Instead, there is one main loop. This alows that the common code
8070 is expanded only once, thus config.status (and configure) is smaller.
8072 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8073 the AC_LIST_FILES and cousins macros are no longer used.
8075 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8076 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8077 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8078 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8079 contain the initialization, nor the for loop, nor the associated
8080 commands; all these go to ...
8081 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8082 _AC_OUTPUT_CONFIG_STATUS.
8083 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8084 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8085 (_AC_OUTPUT_FILE): The creation of the sed script ...
8086 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8087 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8088 _AC_OUTPUT_MAIN_LOOP.
8089 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8090 _AC_CONFIG_COMMANDS): Use ...
8091 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8092 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8093 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8094 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8095 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8096 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8097 ... new macros.
8098 (_AC_CONFIG_UNIQUE): Update.
8099 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8100 Replaced by this ...
8101 (_AC_LIST_TAGS): ... new common macro.
8102 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8103 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8104 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8105 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8106 this didn't belong to the `config commands' section.
8107 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8108 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8109 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8110 to the `config commands' section either.
8111 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8112 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8114 ... and many changes to the comments nearby.
8116 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8117 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8118 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8119 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8120 (#define header templates): The comment at the top of the generated
8121 header now includes the name(s) of the source file(s).
8123 Several unrelated small changes:
8125 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8126 parameter to AC_DIAGNOSE.
8127 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8128 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8129 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8130 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8131 with AU::AC_OUTPUT.
8132 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8133 in AC_OUTPUT doesn't double-quote it either.
8134 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8135 parameters.
8137 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8139 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8140 versions of Portland Group compiler produce single- and double-quoted
8141 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8142 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8144 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8146 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8147 This is a corrected version of yesterday's patch.
8149 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8151 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8152 path, too; insert a "===" to emphasize the line.
8154 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8155 ac_cv_build_alias to ac_build_alias.
8156 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8158 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8159 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8160 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8161 (AC_ARG_VAR): ... here.
8162 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8163 target_alias.
8165 Keep a list of all precious variables and process them with one simple
8166 for loop, instead of expanding all commands, or, OTOH, complicated
8167 processing of output of "set".
8168 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8169 variable names in new macro...
8170 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8171 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8172 a loop to assign all ac_env_* and ac_cv_env_* variables.
8173 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8174 to INIT_PREPARE.
8175 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8176 its value to shell variable ac_precious_vars and call
8177 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8178 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
8179 _AC_ARG_VAR_VALIDATE.
8181 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
8182 and the AC_SUBSTs ...
8183 (AC_INIT): ... here.
8185 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
8186 the ac_subst_files section in config.log.
8188 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
8190 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
8192 * NEWS: New macro AC_C_TYPEOF.

8197 Fix problems reported by Nicolas Joly.
8198 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
8199 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8200 They are generated by the Tru64 v5.1B shell.
8202 2005-07-05 Stepan Kasal <kasal@ucw.cz>
8204 Fix my changes from 2005-07-01; reported by Noah Misch.
8205 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8206 description, the macro now accepts only a single tag.
8207 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
8209 Fix cases when the varsions of Autoconf and Autotest don't match.
8210 Reported by Noah Misch.
8211 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
8212 at_top_builddir, for compatibility with older autotest.
8213 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
8214 is not set, use at_top_builddir, for compatibility with older
8215 versions of autoconf.
8217 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8219 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
8220 Problem reported by Patrick Welche.
8222 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8224 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8225 sed substitution command, so that we allow | in program prefixes
8226 and program suffixes. (& is a problem anyway; we're not fixing
8227 that here.)
8228 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8229 configure_input, top_builddir, srcdir, etc.
8230 * lib/autotest/general.m4 (AT_INIT): Likewise, for
8231 PATH_SEPARATOR in AUTOTEST_PATH.
8233 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
8235 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
8236 for loop over config.site files using `set', to allow
8237 directory names containing IFS characters.
8239 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
8241 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
8242 directories with weird names. Apparently some people like living
8243 on the edge. However, improve the test that "pwd" actually does
8244 report a name for the working directory.
8245 * NEWS: Remove the claim that we test for funny chars in dir names.
8247 2005-07-01 Stepan Kasal <kasal@ucw.cz>
8249 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
8250 replaced ...

8259 about #include <config.h>.
8260 (Generic Functions): Mention the Gnulib project.
8261 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
8263 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
8264 document to output the default config_* lists to config.status.
8265 Don't recognize option --file, if the functionality is not there.
8266 Likewise for --header; moreover, recognize --he and --h as shortcuts
8267 for --help in that case.
8269 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8270 matches the order of execution. No code changed.
8272 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8274 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
8275 single-quoted -cmdline argument in Portland Group compiler.
8276 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8278 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>
8280 * lib/autom4te.in (Automake-preselections): Preselect AC_SUBST_TRACE.
8282 2005-06-29 Stepan Kasal <kasal@ucw.cz>
8284 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
8285 descriptors to child processes; reported by Norman Gray.
8287 2005-06-29 Stepan Kasal <kasal@ucw.cz>
8289 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
8291 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
8292 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8293 (AC_SUBST): Call it.
8294 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8295 the directory specific variables; but don't call it for configure_input.
8297 2005-06-28 Derek Price <derek@ximbiot.com>
8299 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8300 addition.
8302 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8304 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
8305 directory have inherent problems with special characters like spaces,
8306 due to limitations in Make syntax. Problem reported by Alexandre
8307 Duret-Lutz.
8308 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
8309 Also, fix Tru64 porting problem with shell patterns,
8310 reported by Ralf Wildenhues.
8312 2005-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8314 * doc/autoconf.texi (Subdirectories): Fix markup typos.
8316 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8318 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
8320 Fix some more shell quoting problems. Prompted by a bug report
8321 from Justace Clutter.
8322 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8323 variable into diagnostic. Make the diagnostic an error, not a warning,
8324 because we really don't support spaces and suchlike in dir names.
8325 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8326 Don't worry about backslashes in srcdir; it can't happen now.
8327 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8328 Simplify ac_optarg handling.
8329 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8337 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
8339 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8340 that '\|' is not allowed in BREs; recommend using newline separated
8341 list of patterns instead of multiple -e options.
8343 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8345 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8349 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
8351 2005-06-21 Stepan Kasal <kasal@ucw.cz>
8353 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8354 b, t, r, w commands require single space, while : cannot have any.
8355 (Special Shell Variables): Fix sed code this in the example.
8356 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8357 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8359 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
8360 expand to the empty list. Don't use two pairs of m4_changequote,
8361 it's not necessary.
8363 2005-06-20 Derek Price <derek@ximbiot.com>
8365 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8367 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8369 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8370 * doc/autoconf.texi:
8371 Don't mention Solaris versions so much, if a
8372 problem is common to all extant versions of Solaris. Say "SunOS
8373 4" instead of "SunOS" for SunOS 4.
8374 (awk): Mention more of the limitations of traditional Awk.
8375 (cat): Don't talk about cat -v.
8377 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
8379 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
8380 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

8382 to be compatible with glibc strverscmp.
8383 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
8385 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8386 on Mac OS X 10.4 reported by Peter O'Gorman in:
8387 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
8388 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8389 Use shell builtins rather than 'expr', to work around expr bug.
8391 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8393 * doc/autoconf.texi: "filesystem" -> "file system".
8394 "behaviour" -> "behavior".
8395 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8396 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8397 as per POSIX.
8398 * lib/m4sugar/m4sh.m4: Likewise.
8399 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8400 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8402 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8403 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8404 to update the man page. That way, we don't have to check in new
8405 man pages every month.
8407 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8408 quotes and backslashes. Patch from Derek Price.

8413 AS_TR_SH.
8415 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8417 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8418 -u, since it outputs chatter if the input files are the same.
8419 Problem reported by Ralf Menzel.
8421 2005-06-08 Derek Price <derek@ximbiot.com>
8423 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8424 renaming them since they are about to be redefined anyhow.
8426 2005-06-08 Derek Price <derek@ximbiot.com>
8428 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8429 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8430 Move m4_undefine to alphabetical order.
8432 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8434 * README: Recommend GNU M4 1.4.3 or later.
8435 * doc/autoconf.texi (Introduction): Likewise.
8436 Reword to avoid some formatting glitches.
8437 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8438 Clarify explanation of HP compiler bug.
8439 Redo example output tp match current CVS snapshot.
8440 Use @example.org in email addresses when the examples
8441 might get inadvertently cut-and-pasted into user code.
8442 Remove example of autom4te usage that doesn't seem to work now.
8443 Use modern AC_INIT (except when the example is meant to be
8444 shown with Autoconf 2.13).
8445 Update ksh info for Solaris 9 and later.
8446 KB -> kB.
8447 Modernize description of Automake versions a bit.
8448 Don't claim a future version of Autoconf is near.
8449 * doc/install.texi: Reword to avoid some formatting glitches.
8451 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8453 * doc/autoconf.texi: Add [] to examples, so that the manual
8454 follows its own advice about quoting better.
8455 Reword to avoid some formatting glitches.
8456 * doc/installt.exi: Reword to avoid some formatting glitches.
8458 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8459 Tru64 ksh pattern matching bug. Reported against Libtool by
8460 Albert Chin <libtool@mlists.thewrittenword.com> and
8461 Nicolas Joly <njoly@pasteur.fr>.
8463 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8465 m4_cdr of one-member list was [[]] (one-member list containing an
8466 empty string) instead of [] (an empty list. Callers were skewed to
8467 match this misbehaviour. As a consequence of this:
8468 - m4_foreach([x], [], [foo]) expanded to `foo', while
8469 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8470 This bug has been fixed:
8472 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8473 expand to an empty string; print error msg if called without
8474 an argument list.
8475 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8476 misbehaviour; handle [] and [[]] correctly.
8478 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8480 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
8481 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
8482 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8484 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8486 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8487 swallow records with more than 99 fields.
8488 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8489 parse the long line.
8491 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8493 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8494 swallow literals longer than 399. Reported by Ralf Wildenhues.
8495 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8496 to workaround this limitation.
8498 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8500 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8501 to gfortran, and make these the first two compiler names
8502 checked (following the general autoconf preference for gcc).
8504 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8506 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8507 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8508 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8510 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8512 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8513 expression of unbounded size when processing the --list
8514 option. This runs afoul of a limit of 399 bytes per regular
8515 expression on AIX. Problem reported by Ralf Wildenhues.
8517 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
8519 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
8520 * doc/autoconf.texi (Particular Headers): Reword example
8521 for multiline stdbool replacement.
8522 (Setting Output Variables): Reword text a bit. Don't
8523 give all the details about |#_!!_#|.
8524 Reword description of line replacement.
8526 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8528 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8529 now contain newlines, and substituted files must be referenced on
8530 a line alone; the sed scripts to substitute them are now very
8531 different.
8532 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8533 commands can be put in a sed script portably.
8534 * doc/autoconf.texi (Setting Output Variables): Document above
8535 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8536 use of multiline substitution.
8537 * tests/torture.at: No longer expect substitution of newline to fail.
8539 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>

8542 From Ralf Menzel (trivial change).
8544 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8546 * tests/local.at: Don't attempt to check for negated character
8547 classes in shell scripts. The test was too brittle.
8549 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8551 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8552 * doc/autoconf.texi (Limitations of Builtins): Document this
8553 limitation.
8555 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8557 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8558 common code; used in many places in the tree.
8559 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
8560 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
8562 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
8564 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
8565 messages when ac_unique_file is not found.
8566 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8567 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8568 commands, for consistency with AC_MSG_ERROR and such.
8570 * bin/autoconf.as: Make more use of "shift 2" in option processing.
8572 * bin/Makefile.am: Merge the two rules for creating scripts.
8574 2005-05-23 Stepan Kasal <kasal@ucw.cz>

8580 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8582 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8583 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8584 (ac_top_builddir): ... this ...
8585 (ac_top_build_prefix): ... to this; the old name is also kept, for
8586 backward compatibility.
8587 (ac_top_builddir_sub): New variable, without the trailing slash,
8588 always nonempty.
8589 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8590 * doc/autoconf.texi (Configuration Actions): Rename
8591 ac_top_builddir to ac_top_build_prefix.
8592 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8593 at_top_builddir to at_top_build_prefix.

8596 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8598 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
8599 of confdefs.h .
8601 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8603 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8604 argument to m4_foreach. I guess it was necessary in the past,
8605 but I think it's a no-op now.
8607 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8609 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8610 ``cat <<_ACEOF'' commands to one.
8611 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8612 * lib/autoconf/status.m4: On various places, use expr instead of
8613 ``echo|sed.''
8614 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8615 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8616 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8617 a range.
8618 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8619 the wrong patterns between ``case'' and ``esac.'' The previous
8620 code had false positives.
8622 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8624 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8625 as on 2005-05-02.
8626 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
8627 Mention LIBOBJDIR.

8688 * doc/autoconf.texi (Autoconf Language): Be more precise about
8689 quoting rules. Problems noted by Stepan Kasal.
8690 Also, throughout this document, be more careful about white space.
8691 "blank", "white space", and "space" all have different meanings
8692 and we should be careful to say what we mean.
8694 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
8696 Fix C++ related problems reported by Werner Lemberg.
8697 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

8729 not newline.
8731 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
8732 by AC_DEFINE; it was a mistake.
8733 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
8735 2005-04-25 Stepan Kasal <kasal@ucw.cz>

8743 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8744 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8745 comment and reduce m4_default([foo], []) to [foo].
8746 (m4_strip): Update the explanation.
8748 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8750 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8751 Remove core.conftest.* too; it's generated by Tru64 5.1.
8752 Problem reported by Jennis Pruett.
8753 * lib/autoconf/functions.m4
8754 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8755 Don't bother to remove core files; AC_RUN_IFELSE should do that
8756 for you.

8777 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8779 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8780 as well as configure.in. Problem reported by Gregorio Guidi.
8782 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8784 * doc/autoconf.texi (Particular Functions): Use gnulib's current
8785 pattern for alloca snippet.

8797 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8798 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8800 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8802 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8803 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8804 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8805 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8806 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8808 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8810 * NEWS: The configure command now warns you if you attempt to use
8811 a directory whose name contains a special character like space,
8812 newline, or "\".
8813 * doc/autoconf.texi (Installation Directory Variables): Allow
8814 "," in file names. Do not use \@; it's not a portable regexp.
8815 * bin/Makefile.am (edit): Likewise.
8816 * lib/Makefile.am (edit): Likewise.
8817 * tests/Makefile.am (edit): Likewise.

8822 * doc/autoconf.texi (File System Conventions): Warn about
8823 unportable file names.
8824 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8825 (AC_INIT): Use it.
8826 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8827 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8828 ac_pwd, and quote srcdir.
8829 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8831 * doc/autoconf.texi: Fix some systematic formatting problems.
8832 ".)" needs a following @: if not at the end of a sentence, and
8833 similarly for "!)". "etc." should be preceded by a comma.
8834 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8836 2005-03-22 Bruno Haible <bruno@clisp.org>
8838 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8839 argument is often called 'build-aux'.
8841 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8843 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8844 macro AC_TRY_LINK is obsolete.
8845 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8846 `AC_CONFIG_FILES'.
8848 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8850 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8851 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8852 from a Common Lisp's `cl'.
8853 (AC_PROG_CXX): Behave according to the documentation: don't
8854 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8855 make the variable CCC precious; use `cl.exe', not `cl'.
8857 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8858 Alexandre Duret-Lutz <adl@gnu.org>
8860 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8861 /dev/null, as "configure" shouldn't read stdin, and this insulates
8862 us from problems (e.g., when testing for "cl"). Also, do this
8863 redirection before invoking "hostname" or "uname", and keep the
8864 original input stream available via...
8865 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8866 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8867 bother with "</dev/null" since it's now done at the top of
8868 'configure'.
8869 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8870 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

8876 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8878 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8879 newline if neither \c nor -n work, as that would output two
8880 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8882 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8884 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8885 This causes that any required macros inside will get before the if.
8886 * doc/autoconf.texi (autom4te.cache): A typo.
8888 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8890 Undo previous change, except keep the change to
8891 lib/autoconf/programs.m4 that replaced grep with shell
8892 pattern-matching. This is because net-snmp configure reads stdin.
8893 Reported by Noah Misch.
8895 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8897 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8898 from /dev/null, as "configure" shouldn't read stdin, and this
8899 insulates us from problems (e.g., when testing for "cl").
8900 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8901 before invoking "hostname" or "uname".
8902 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8903 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8904 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8905 "</dev/null" since it's now done at the top of 'configure'.
8906 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8907 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8908 Also, replace grep with shell pattern-matching, to save a process.
8910 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8912 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8913 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8914 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8915 compiler.
8917 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8919 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8920 grep -q isn't portable. Improve grep -s explanation.
8921 Problem reported by Dan Manthey.
8923 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8925 * doc/autoconf.texi (Special Shell Variables): Clarify
8926 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8928 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8930 * doc/autoconf.texi: Use @acronym for DJGPP.
8931 Fix some @code's that should have been @env's, and vice versa.
8932 Sort environment variable names.
8933 Mention that shells no longer inherit IFS.
8934 Don't recommend PATH_SEPARATOR=';' so strongly.
8935 Mention that $RANDOM might expand to the empty string.
8936 "symlink" and "soft link" -> "symbolic link".
8937 Improve mktemp description (reported by Bruno Haible).
8939 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8941 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8942 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8943 Likewise.

8949 * NEWS: Mention AT_COPYRIGHT.
8951 * tests/local.at (AT_CMP): Use diff directly on input files rather
8952 than copying them.
8954 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8955 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8957 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8958 and Paul Eggert <eggert@cs.ucla.edu>

8967 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8968 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8969 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8970 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8971 (Standard regular expressions): New test.

8973 excess test name quoting.
8974 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8975 CPPFLAGS to `configure' instead of setting it in `configure'.
8977 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8978 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8979 on some platforms.
8981 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8982 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

9010 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
9012 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
9013 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
9015 Try not to generated lines of unlimited length, as POSIX places a
9016 2047-byte limit on line length of portable text files.
9017 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
9018 Use newline as a separator, not space.
9019 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
9020 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
9021 space.
9023 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9025 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
9026 as_func_*. Add test to check whether positional parameters
9027 are restored after function return.
9029 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
9031 * doc/autoconf.texi (Special Shell Variables): Mention _,
9032 BIN_SH, DUALCASE. Say that variables other than "status" are safe
9033 if they contain a lower-case letter. The DUALCASE problem was
9034 reported by Ralf Wildenhues.
9036 * bin/autoconf.as: Don't exit with status 0 after write failure
9037 with --help or --version.

9044 Unicos 9 sed limitations.
9045 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

9049 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
9051 * man/Makefile.am (.x.1): Go back to the simple solution, but take
9052 care to echo the commands, so the user knows what's going on.
9053 Modified from a suggestion by Stepan Kasal.
9055 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

9074 2005-01-29 Stepan Kasal <kasal@ucw.cz>
9076 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9077 Update the long comment explaining it.
9079 m4_require no longer writes an ``is required by'' line to the
9080 execution stack. It contains only one bit of non-redundant
9081 information: that the macro was required, not called. And even
9082 this bit is useless in most situations: have you ever met a macro
9083 which both calls and requires the same macro?
9085 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9086 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9087 macro.
9088 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9089 (m4_expansion_stack_pop): Remove the misplaced comment.
9090 (m4_require): Don't put the ``is required by'' line to the
9091 execution stack; slightly improve the out-of-a-defun error message.
9092 (_m4_divert_grow): New macro, counter for the temporary diversions.
9093 (_m4_require_call): Use it.
9094 * tests/m4sugar.at (m4_require): Expect output without the
9095 ``is required by'' messages.
9097 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9099 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
9100 rather than x for expr.
9102 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
9103 this is safe.
9104 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
9105 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

9116 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
9117 from masters, so that FileUtils.pm's update_file provide --force
9118 support.
9119 * bin/autoheader.in: Pass $force to update_file so that
9120 config.h.in is always recreated when --force.

9124 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
9126 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9128 * doc/autoconf.texi (Limitations of Builtins): Clarify that
9129 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
9131 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
9133 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
9134 Warn about newline stripping in `` and $(). Update Solaris
9135 version to 9.
9136 (Limitations of Builtins): Use expr "X...", not expr "x...", as
9137 X insulates us from future changes to Posix.
9138 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
9139 stripping.
9141 2005-01-19 Stepan Kasal <kasal@ucw.cz>

9159 ulongval to be static, to avoid unwanted GCC warning. Problem
9160 reported by Michael Jennings via Daniel Reed; see
9161 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
9163 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
9165 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

9170 new variables.
9172 2005-01-04 Noah Misch <noah@cs.caltech.edu>
9174 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
9175 not seem to work, assume it does set $(MAKE).

9178 2005-01-03 Stepan Kasal <kasal@ucw.cz>
9180 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

9186 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
9187 (_m4_divert_n_stack): New macro; the expansion is
9188 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
9189 otherwise.
9190 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
9191 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
9192 stored in _m4_divert_diversion or _m4_divert_dump.
9193 (m4_divert_pop): When the parameter is given, compare the symbolic
9194 name with the last diversion pushed on the stack. Previously, the
9195 current diversion was compared with the numeric value of the
9196 diversion given as the parameter.
9197 (m4_require): If the macro hasn't been expanded yet, call ...
9198 (_m4_require_call): this new macro.
9200 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9505 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9506 "char c = '\200';" rather than "char c = 0x80;" as the

9508 overflow on signed char hosts.

9624 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

9685 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9687 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9688 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9689 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9690 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9692 More fixes to support spaces in the name of the build directory.
9693 This isn't a complete fix but it's an improvement.
9695 * bin/autoconf.as (autom4te_options): New var.
9696 Use it instead of appending to AUTOM4TE, so that we can allow
9697 spaces in the build directory's absolute name.
9698 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9699 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9700 AT_CHECK_NOESCAPE): Likewise.
9701 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

9713 and isnan. From a suggestion by Kevin Ryde.
9715 * lib/Autom4te/General.pm (END): Return correct exit status even
9716 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9718 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9720 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9721 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9722 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9724 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9726 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9727 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9728 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9729 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9730 * lib/autom4te.in (Automake-preselections): Preselect
9731 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9733 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9735 * lib/autom4te.in (Automake-preselections): Preselect
9736 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9737 trace them.
9739 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9741 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9742 Tru64.

9744 Document problem with "`""`" in pdksh POSIX mode.
9746 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9748 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9749 with pdksh, too. Problem reported by Patrick Welche via
9750 Gary V. Vaughan.
9751 * doc/autoconf.texi (Shellology): Note that set -o posix is
9752 useful for pkdsh, too.
9754 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9756 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9757 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9758 Don't fail if ENV or BASH_ENV is readonly.
9759 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9760 etc. are read only. Problem reported by Ludovic Courtes.
9762 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9764 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9765 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9766 (trivial change)
9768 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9770 * doc/autoconf.texi (File System Conventions): Warn about
9771 names like "aux". Problem reported by Eric Blake.
9773 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9774 by zero instead of array size, so that we can use any arithmetic
9775 constant expression (instead of requiring an integer constant
9776 expression). This allows us to test expressions like DBL_MAX <
9777 LDBL_MAX, which didn't conform to the C standard using the old
9778 method.
9779 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9780 now that we can do floating-point tests at compile time.
9782 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9784 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9785 and LDBL_EPSILON, as the resulting expression isn't an
9786 integer constant expression and violates the C standard.
9787 Problem reported by Nelson H. F. Beebe. Also, check
9788 for "L" suffix, and check that long double doesn't have
9789 worse range or precision than double, that mixed-mode
9790 arithmetic doesn't generate a diagnostic, that double
9791 constants fit in long double.
9793 2004-06-03 Kevin Ryde <user42@zip.com.au>
9795 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9796 malloc(0) and realloc(NULL,size).
9798 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9799 Bob Proulx.
9801 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9803 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9804 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9805 by Jim Meyering.
9807 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9809 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9810 can be rewritten using if-then-else. Suggested by Bruno Haible.
9812 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9814 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9815 Problem reported by Stepan Kasal.
9817 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9819 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9820 change). Patch reported by Ralf Wildenhues in
9821 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9823 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9824 function F exists if the compiler and linker let you compile an
9825 expression like (F != 0). Recent versions of GCC optimize away
9826 the reference to F in that case, since every function address must
9827 be nonzero, so the link succeeds even if F does not exist.
9828 Problem reported by Manu in
9829 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9831 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9832 "Unix". Many uses changed.
9833 (Limitations of Builtins): Explain better why the ! command isn't
9834 portable.
9836 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9838 * lib/autom4te.in (Automake-preselections): Preselect
9839 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9841 2004-05-19 Kevin Ryde <user42@zip.com.au>
9843 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9844 referencing AC_FUNC_STRERROR_R.
9846 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9847 note pessimistic assumption when cross compiling.
9849 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9851 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9852 (until 2004) invoked subcommands with sh -e, contra POSIX.
9853 Reported by Kevin Ryde.
9855 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9857 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9858 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9859 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9860 `test -f " /usr/bin/grep"', which _always_ failed.
9861 (AC_PROG_SED): Ditto bogus PATH fix.
9862 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9863 requires that grep correctly supports _multiple_ `-e' options, rather
9864 than stating only that grep should accept `-e'.
9866 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9868 Port to C99, which requires that 'exit' be declared.
9870 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9871 to ensure that stdlib.h is included.
9872 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9873 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9874 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9875 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9876 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9877 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9878 when using 'exit' in a test; C99 requires that 'exit' be declared.
9880 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9882 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9883 now prefers 'grep' implementations that accept -e.
9884 (Limitations of Usual Tools): Describe problems of traditional
9885 egrep and fgrep with long input lines, and of traditional grep
9886 with -e.
9887 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9888 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9889 All callers changed. Append /usr/xpg4/bin to the PATH, for
9890 Solaris.
9891 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9892 the user with complaints about multiple -e options.
9893 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9894 Define it with AC_PROG_GREP.
9895 * configure.ac (AC_PROG_GREP): Add.
9896 * lib/freeze.mk (GREP): New macro.
9898 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9900 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9901 a possible candidate only after all others fail, rather than
9902 consulting it first. This improves backward compatibility by
9903 better reflecting the way shell selection occurred in previous
9904 versions of Autoconf, and should help to avoid triggering latent
9905 problems in other packages, such as the one in Automake where zsh
9906 is not handled robustly:
9907 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9908 Although it is not Autoconf's responsibility to work around
9909 problems in Automake, it nevertheless makes sense to avoid
9910 introducing unnecessary incompatibilites.
9912 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9913 Gary V. Vaughan <gary@gnu.org>
9915 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9916 how deeply nested we are when a suitable tool is found, set the
9917 ac_path_TOOL_found flag.
9918 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9919 nested we are in this macro. Break out of all 3 nested loops if
9920 ac_path_TOOL_found is set.
9922 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9924 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9925 of the _AS_PATH_WALK loop too if GNU flavor is found.
9927 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9929 * doc/autoconf.texi (Limitations of Make): Update documentation
9930 for `$<'. New entry `Long lines', based on a report from Simon
9931 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9932 paragraph about DJGPP, based on a mail from Richard Dawe.
9934 2004-04-20 Paul Eggert <eggert@twinsun.com>
9936 * tests/c.at (C keywords): Don't assume that GCC supports
9937 "restrict" and "inline", as sufficiently-old GCC versions do not
9938 (also, GCC configured to be in pedantic C89 mode does not).
9939 Problem reported by Sumit Pandya in:
9940 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9942 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9943 consider -g to work if it generates warnings when plain compiles
9944 don't. Problem reported by Braden McDaniel in:
9945 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9947 * doc/autoconf.texi (Slashes): New section, to document a problem
9948 reported by Jim Meyering in:
9949 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9951 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9952 linker output files before linking, to work around IRIX 6 linker bug.
9953 Problem reported by Rainer Orth in:
9954 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9956 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9958 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9959 best tool so far counter rely on the tool path variable name to
9960 avoid checks for one tool being affected by the results of running
9961 the length check on a previous tool.
9963 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9964 match expression argument, as different greps have different
9965 regular expression flavours.
9966 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9967 literals.
9968 (AC_PROG_EGREP): Pass 'EGREP$'.
9969 (AC_PROG_GREP): Pass 'GREP$'.
9971 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9973 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9974 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9976 2004-03-29 Paul Eggert <eggert@twinsun.com>
9978 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9979 Types, Specific Compiler Characteristics, System Services,
9980 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9981 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9982 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9983 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9984 Likewise.
9985 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9986 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9987 AC_TYPE_OFF_T): Likewise.
9988 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9989 Likewise.
9991 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9992 pacify libtool 1.5.2. Fix quoting problems in sed command.
9994 2004-03-28 Paul Eggert <eggert@twinsun.com>
9996 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9997 now defines HAVE_DECL_TZNAME if it is declared, when
9998 HAVE_STRUCT_TM_TM_ZONE is not defined.
9999 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
10000 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
10001 for HAVE_TZNAME.
10003 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
10005 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
10006 superfluous backslashing of quotes (") in sed expressions;
10007 thanks to Paul Eggert.
10009 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
10011 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
10012 Fortran compiler is ifort, also added pghpf; thanks to Nelson
10013 H. F. Beebe for the bug report.
10015 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
10017 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
10018 quoted -cmdline argument in Portland Group compiler (bug
10019 reported by Jeffrey J. Barteet).
10021 2004-03-25 Kevin Ryde <user42@zip.com.au>
10023 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
10024 (Run Time): ... here, where it's now mentioned.
10026 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
10028 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
10029 inherits from language Autoconf-without-aclocal-m4.
10030 (Customizing autom4te): Adjust example; the cache must now be
10031 disabled for language Autoconf-without-aclocal-m4.
10033 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
10034 Nathanael Nerode <neroden@twcny.rr.com>
10036 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
10037 AC_CHECK_TOOLS): Warn if a cross-tool is found without
10038 a prefix.
10039 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
10040 AC_CHECK_TARGET_TOOLS): New macros.
10041 * doc/autoconf.texi (Generic Programs): Document
10042 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
10043 AC_CHECK_TARGET_TOOLS, and warn for future changes
10044 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
10045 AC_CHECK_TOOLS.
10046 (Specifying Names): Document the reason for these future
10047 behavioral changes.
10048 * tests/mktests.sh: Do not generate tests for the
10049 new macros.
10050 * NEWS: Document these changes.
10052 * doc/autoconf.texi: Avoid macros with unbraced arguments,
10053 they make TeX hang up.
10055 2004-03-15 Paul Eggert <eggert@bogus.example.com>
10057 * NEWS: New macro AC_CHECK_ALIGNOF.
10058 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
10059 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
10060 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
10061 vowel.
10062 (AC_CHECK_ALIGNOF): New macro.
10063 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
10064 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
10065 those for sizeof.
10067 2004-03-03 Paul Eggert <eggert@twinsun.com>
10069 * bin/Makefile.am (edit): Don't use $< in a context where
10070 POSIX doesn't require support for it. Use $@.in instead.
10071 Problem reported by Anthony N. Frasso in
10072 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
10073 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
10075 2004-02-23 Gary V. Vaughan <gary@gnu.org>
10077 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
10078 from the next generation of Libtool.

10084 is not always thread-safe. Report from Nathanael Nerode.
10086 2004-02-18 Paul Eggert <eggert@twinsun.com>
10088 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10089 problem on QNX reported by Stephen Rasku in
10090 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
10092 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10093 $(m4sh_m4f_dependencies); this removes a FIXME.
10094 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10095 (MAINTAINERCLEANFILES): Split into pieces,
10096 one per related section. Add $(srcdir)/wrapper.in.
10098 2004-02-09 Paul Eggert <eggert@twinsun.com>
10100 * doc/autoconf.texi (Setting Output Variables): Emphasize that
10101 AC_SUBST provides no portable way to escape literal newlines.
10103 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10104 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10105 Darwin uses -lcrt2.o and there's little point to cataloging all
10106 the system variants. Partial fix reported by Andreas Waechter in:

10122 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
10123 the behavior of the third argument.
10124 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
10125 correctly the behavior of the third argument. Document
10126 what the three macros that AU_DEFUN defines do. Fix
10127 warning message when the third argument includes $0
10128 (reported by Alexandre Duret-Lutz).

10131 Eric Sunshine <sunshine@sunshineco.com>
10132 Paul Eggert <eggert@twinsun.com>
10134 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

10138 (_AS_SHELL_FN_SPY): New macro.
10139 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
10140 macros.
10141 (AS_SHELL_SANITIZE): Remove loop to find better shell
10142 and documentation for the parameter.
10143 (_AS_DETECT_BETTER_SHELL): Move it here.
10144 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
10145 (_AS_RUN): Move it here, support testing with eval.
10146 (AS_REQUIRE_SHELL_FN): Require shell functions when
10147 it is used.
10148 (_AS_LINENO_WORKS): Put around braces, we do not
10149 trigger the bash bug anymore.
10150 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10151 use AS_INIT_WITH_SHELL_FN.
10152 * bin/autoconf.in, tests/wrapper.in: Regenerated.
10154 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10156 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
10157 * doc/autoconf.texi: Don't say that the third parameter
10158 is broken.
10159 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
10160 (AU_DEFUN): Honor the third parameter, create autoupdate
10161 macros with AU_DEFINE.
10162 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
10163 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
10164 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
10165 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
10166 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
10167 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
10168 AC_XENIX_DIR): Likewise.

10170 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
10171 * lib/autoconf/status.m4: Remove FIXME.

10174 configure.ac.
10175 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
10176 of autoupdate.
10178 2004-01-28 Paul Eggert <eggert@twinsun.com>
10180 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
10181 copyright years.
10182 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
10183 2003 (except 1997) to the list of copyright years. This undoes
10184 the 2003-05-22 change, which removed the older years from the list.
10185 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
10187 2004-01-27 Gary V. Vaughan <gary@gnu.org>
10188 Albert Chin-A-Young <china@thewrittenword.com>
10190 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
10191 grep or ggrep program in PATH that accepts as long lines as
10192 possible.
10193 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
10194 AC_PROG_GREP.
10195 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
10196 egrep and fgrep respectively if $GREP -E/-F don't work.
10197 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10198 _AC_PROG_GREP, and AC_PROG_SED.
10199 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10200 longest input length accepted by a command.
10201 (AC_PROG_SED): Use it.
10202 * doc/autoconf.texi (Particular Programs): Document the changes.
10203 * NEWS: Updated.
10205 2004-01-27 Paul Eggert <eggert@twinsun.com>
10207 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
10208 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10209 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
10210 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
10212 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
10213 bin/autoconf.in, config/Makefile.in, config/config.guess,
10214 config/config.sub, config/install-sh, config/mdate-sh,
10215 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,
10216 lib/Makefile.in, lib/Autom4te/Makefile.in,
10217 lib/autoconf/Makefile.in, lib/autoscan/Makefile.in,
10218 lib/autotest/Makefile.in, lib/emacs/Makefile.in,
10219 lib/m4sugar/Makefile.in, man/Makefile.in, man/autoconf.1,
10220 man/autoheader.1, man/autom4te.1, man/autoreconf.1,
10221 man/autoscan.1, man/autoupdate.1, man/config.guess.1,
10222 man/config.sub.1, man/ifnames.1, tests/Makefile.in,
10223 tests/acc.at, tests/acfortran.at, tests/acfunctions.at,
10224 tests/acgeneral.at, tests/acheaders.at, tests/aclang.at,
10225 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
10226 tests/actypes.at: Regenerate and/or sync with original
10227 sources.
10229 2004-01-26 Paul Eggert <eggert@twinsun.com>
10231 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10232 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10233 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10234 not <inttypes.h>. Problem reported by Tim Mooney in
10235 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10236 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10237 Likewise.
10239 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10240 otherwise "make check" fails because it forbids cmp (I guess
10241 because cmp treats files as binary on DOS-like systems).
10243 * tests/mktests.sh: Update copyright date to 2004, since some tests
10244 have changed in 2004.
10246 2004-01-23 Gary V. Vaughan <gary@gnu.org>
10248 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
10249 non-truncating sed or gsed program in PATH.
10250 * tests/acprograms.at: Add it.
10251 * doc/autoconf.texi (Particular Programs): Document it.
10252 * NEWS: Updated.
10254 2004-01-15 Paul Eggert <eggert@twinsun.com>
10256 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10257 -std1 disables some useful extensions on Tru64. Problem reported
10258 by N. Lichtmaier in
10259 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10261 2004-01-14 Paul Eggert <eggert@twinsun.com>
10263 * doc/autoconf.texi (Programming in M4sh): Document that
10264 AS_MKDIR_P succeeds if the destination is a symbolic link
10265 to an existing directory.
10266 (Limitations of Usual Tools): Note that mkdir -p might not
10267 succeed on symlinks to directories.
10269 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10271 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10272 * bin/autoheader.in: Grammar fix in message.
10273 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10274 Test for dir before calling mkdir -p. (trivial changes)
10276 2004-01-13 Eric Blake <ebb9@byu.net>
10278 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10279 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10281 2004-01-10 Jim Meyering <jim@meyering.net>
10283 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10285 2004-01-09 Paul Eggert <eggert@twinsun.com>
10287 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10288 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10289 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10290 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10291 AC_COMPILE_IFELSE, since we now assume our caller invokes
10292 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10293 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10294 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10295 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10297 2004-01-07 Paul Eggert <eggert@twinsun.com>
10299 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10300 `"'...'"`, as it's confusing (and I suspect it may not work on
10301 some platforms). The code was incorrect anyway, as it assumed
10302 that \$ evaluated to itself in that context. Reported by
10303 Alexandre Duret-Lutz.
10305 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10307 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10308 and _LT_AC_TAGCONFIG.
10310 2004-01-06 Paul Eggert <eggert@twinsun.com>
10312 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10313 example, and add more examples. Reported by Eric Sunshine.
10315 2004-01-05 Paul Eggert <eggert@twinsun.com>
10317 * doc/autoconf.texi (Limitations of Usual Tools):
10318 Remove warning against "rm -fr" introduced yesterday; it
10319 was a false alarm.
10321 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
10322 autoscan, autoupdate, ifnames): Don't use chmod -w.
10323 * lib/Makefile.am (autom4te.cfg): Likewise.
10324 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
10325 "chmod -w".
10327 2004-01-04 Paul Eggert <eggert@twinsun.com>
10328 Paolo Bonzini <bonzini@gnu.org>
10330 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
10331 by doing lineno substitution only on lines containing "$LINENO".
10333 2004-01-04 Paul Eggert <eggert@twinsun.com>
10335 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10336 Use "rm -f" to remove conftest.sed, not plain "rm".
10337 Bug reported by David Relson in
10338 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10340 * Makefile.am (autom4te-update):
10341 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10342 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10343 * doc/autoconf.texi (Guidelines): Likewise.
10344 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
10345 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.
10346 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10347 * lib/autotest/general.m4 (AT_INIT): Likewise.
10348 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
10349 * tests/Makefile.am (clean-local): Likewise.
10350 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
10351 srcdir): Likewise.
10352 * doc/autoconf.texi (Limitations of Usual Tools):
10353 Warn against "rm -fr".
10355 2004-01-03 Paul Eggert <eggert@twinsun.com>
10357 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10358 -c -o might not work. From a suggestion by Kevin Ryde.
10359 (C Compiler, Generating Sources, Limitations
10360 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10361 Don't put '-o' after non-options, as POSIX doesn't allow this.
10362 Mention that cc's name might be gcc or c89 or whatever.
10364 2004-01-04 Kevin Ryde <user42@zip.com.au>
10366 * doc/autoconf.texi: Add various further index entries.
10368 2003-12-29 Paul Eggert <eggert@twinsun.com>
10370 * bin/autoreconf.in (autoreconf_current_directory):
10371 Fix typo: mkdir without umask arg.
10373 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10375 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10376 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10377 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10378 explanation clearer.
10380 2003-12-24 Andreas Schwab <schwab@suse.de>
10382 * doc/autoconf.texi (Default Includes): Fix misspelling of
10383 AC_INCLUDES_DEFAULT.
10385 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10387 * configure.ac: Test if sh -n works.
10388 * configure: Regenerate.
10389 * tests/atlocal.in: Store the result here.
10390 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
10391 tools.at, looking in atlocal's ac_cv_sh_n_works instead
10392 of explicitly testing.
10393 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10394 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10395 * tests/tools.at (Syntax of the shell scripts): Simplify
10396 using AT_CHECK_SHELL_SYNTAX.
10397 (Syntax of the Perl scripts): Remove definition of
10398 AT_CHECK_PERL_SYNTAX.
10400 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10402 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
10403 stderr to /dev/null.
10404 * bin/autoconf.in: Regenerate.
10405 * bin/wrapper.in: Regenerate.
10407 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
10409 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
10410 Extracted from AS_SHELL_SANITIZE.
10411 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
10412 macros.
10413 (AS_SHELL_SANITIZE): Move reinvocation code from
10414 _AS_LINENO_WORKS, use it to find out if shell
10415 functions work.
10416 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
10417 does not work.

10429 * config/announce-gen (&print_locations, &print_signatures)
10430 (&sizes): New.
10431 Use them.
10432 No longer rely on Gnus to inline the list of signatures: compute
10433 them on the fly.
10435 2003-11-24 Akim Demaille <akim@epita.fr>
10437 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
10438 override some files.
10439 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
10440 From Debian Autoconf 2.58.
10442 2003-11-24 Akim Demaille <akim@epita.fr>
10444 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote $ac_popdir

10450 * TODO: Remove already done things. Update the part about finding
10451 tools for the target.

10455 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H, AC_DIR_HEADER):
10456 Make wording more consistent.
10457 * lib/autoconf/specific.m4 (AC_CYGWIN, AC_EMXOS2, AC_MINGW32):
10458 Explain the transition better.
10459 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS): Explain
10460 the transition better.
10462 2003-11-24 Paolo Bonzini <bonzini@gnu.org>
10464 * doc/autoconf.texi (Obsoleting Macros): Don't document the third
10465 parameter of AU_DEFUN.
10466 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
10467 (AU_DEFUN): Remove the third parameter, it was not used.
10468 Use AC_DEFUN directly, not AU_DEFINE.
10469 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
10470 the expanded body, consistently with other macros such as AC_USG.
10472 2003-11-17 Paul Eggert <eggert@twinsun.com>
10474 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
10475 into the initial confdefs.h, to work around a bug in NextStep 3.3
10476 patch 3 reported by Eric Sunshine.
10478 2003-11-15 Kevin Ryde <user42@zip.com.au>
10480 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10481 than $target since the latter is not usual, add guidelines on when to
10482 use or not use the system type.
10484 2003-11-12 Derek Price <derek@ximbiot.com>
10486 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

10495 2003-11-12 Akim Demaille <akim@epita.fr>
10497 * configure.ac: Bump to 2.59a.
10498 Require 2.59.
10500 2003-11-06 Akim Demaille <akim@epita.fr>
10502 Version 2.59.
10504 2003-11-05 Alexandre Duret-Lutz <adl@gnu.org>
10506 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
10507 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
10508 and ac_abs_top_srcdir are absolute paths.
10509 * lib/m4sugar/m4sh.m4 (AS_SET_CATFILE): Remove misleading comment.

10515 2003-11-05 Kevin Ryde <user42@zip.com.au>

10533 AC_CONFIG_FILE([d1/foo:d2/foo]) triggers error messages when
10534 computing the absolute path to d1 in the source hierarchy: it may
10535 not exist at all. So don't cd into it.
10536 From Alexandre Duret-Lutz.
10537 http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00205.html

10647 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10649 2003-10-10 Andreas Schwab <schwab@suse.de>
10651 * bin/autoheader.in: Avoid empty first line in --version and

10663 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10664 -mGLOB_options_string stuff for Intel ifc, which can cause
10665 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10666 pattern-matching instead of grep.
10668 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>

10678 * NEWS: Updated.

10686 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10688 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10689 cache variable instead of $G77 to decide whether to include -O2,
10690 since $G77 is specific to Fortran 77.

10694 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

10699 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10700 arguments so that it can be used with syntax identical to
10701 AC_PROG_F77, and so that we can more easily decide to
10702 remove/deprecate the DIALECT optional argument in the future if it
10703 proves troublesome.
10704 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10705 non-freeform-supporting compilers. Document freeform flags.
10707 2003-10-03 Akim Demaille <akim@epita.fr>
10709 * configure.ac: Look for emacs, not macs.
10710 Reported by Eric Sunshine.
10712 2003-10-03 Akim Demaille <akim@epita.fr>
10714 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10715 * bin/autoreconf.in (autoreconf_current_directory): Create the
10716 AUX_DIR if needed, for sake of automake --add-missing etc.
10717 Suggested by Alexandre Duret-Lutz.
10719 2003-10-03 Akim Demaille <akim@epita.fr>
10721 * configure.ac: Quotation and formatting changes.

10751 (@news_file): this.
10753 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
10755 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10756 have been created when invoking the compiler.

10768 Problem reported by Lars J. Aas in
10769 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10770 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10771 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10772 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10774 2003-09-26 Akim Demaille <akim@epita.fr>
10776 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10777 directory for AC_CONFIG_COMMANDS' first argument exists.
10778 This makes valid the invocation of _AC_SRCPATH that follows.
10779 Reported by Eric Sunshine.
10780 * doc/autoconf.texi (Configuration Commands): Adjust.
10782 2003-09-26 Akim Demaille <akim@epita.fr>
10784 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10785 Reported by Ralf Corsepius.
10787 2003-09-26 Akim Demaille <akim@epita.fr>
10789 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10790 arguments.

10792 From Bruno Haible.
10794 2003-09-26 Paul Eggert <eggert@twinsun.com>
10796 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

10801 2003-09-26 Akim Demaille <akim@epita.fr>
10803 The test suite are sometimes assigning timings incorrectly.
10804 Reported by Henk Krus.
10805 Diagnosed by Nicolas Joly.
10807 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10808 AT_help_all.
10809 Instead of making AT_help a sequence of assignments to grow
10810 $at_help_all, just make AT_help_all be the growing contents of
10811 $at_help_all, and make a single assignment in...
10812 (AT_INIT): here.
10813 (at_times_skip): Flip the meaning and rename as...
10814 (at_times_p): this.
10815 (AT_INIT): When summarizing the test that ran, remove
10816 $at_times_file after use, and check it is present before trying to
10817 use it.
10819 2003-09-25 Akim Demaille <akim@epita.fr>
10821 Version 2.57d.
10823 * bin/Makefile.am (edit): Handle '@configure_input@'.
10824 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10825 (ifnames): chmod -w.
10826 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10827 executables, not bin/ executables! Otherwise all the magic needed
10828 to find non installed files is turned off. This caused a failure
10829 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10830 as found in its environment (sent by tests/autoreconf): pointing
10831 to bin/autom4te that could not find its files.
10832 * tests/mktests.sh: Force the replacement of generated files, for
10833 the sake of "mv" program that are interactive when overwriting a
10834 -w file.
10835 * config/install-sh: Upgrade from CVS Automake.
10837 2003-09-23 Paul Eggert <eggert@twinsun.com>

10842 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10843 Paul Eggert <eggert@twinsun.com>
10845 Trivial change to support GCC's configuration procedure.
10846 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10847 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10848 about inconsistency if the preprocessor is set to give errors for
10849 any warning.

10878 2003-09-10 Akim Demaille <akim@epita.fr>
10880 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10881 willing to edit the output files.
10883 2003-09-10 Akim Demaille <akim@epita.fr>
10885 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10886 and AC_FC_FREEFORM.
10887 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10888 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10890 2003-09-09 Akim Demaille <akim@epita.fr>

10903 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10904 Improve the accuracy of the wording about obsolescence.
10905 From a suggestion by Ian Lance Taylor in
10906 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10908 2003-09-05 Paul Eggert <eggert@twinsun.com>
10910 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10911 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10913 2003-09-04 Akim Demaille <akim@epita.fr>
10915 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10916 AC_FUNC_WAIT3.
10918 2003-09-04 Akim Demaille <akim@epita.fr>
10920 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10921 (freeze): When exiting, use $exit_code.
10922 * lib/autoconf/fortran.m4: Comment changes.
10924 2003-09-04 Akim Demaille <akim@epita.fr>
10926 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10928 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10930 Add support for newer Fortran dialects. The F77 interface is
10931 unchanged, and continues to support Fortran 77. New FC macros
10932 correspond to all the old F77 macros, with output variables FC,
10933 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10934 available dialect, but older dialects can be specified. There are
10935 new macros AC_FC_SRCEXT to set the source extension, and
10936 AC_FC_FREEFORM to accept free-form source files.
10938 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10939 New macros.
10940 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10941 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10942 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),

10955 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10956 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10957 Rewrite in terms of the above.
10958 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10959 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
10960 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
10961 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
10963 2003-09-02 Paul Eggert <eggert@twinsun.com>
10965 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10966 Document problems with timestamp resolution that 'make', 'cp -p', and
10967 'touch -r' have.
10969 2003-08-27 Akim Demaille <akim@epita.fr>
10971 * tests/m4sugar.at (cross_warning): Make sure to enable the
10972 output, so that we can track spurious m4sugar output.
10973 * tests/local.at: Require 2.57.
10974 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10975 are defaulted by AT_CHECK anyway.
10976 Use AT_CHECK_AUTOM4TE.
10977 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10978 missing dnl.
10980 2003-08-27 Akim Demaille <akim@epita.fr>
10982 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10983 when -Wobsolete is set.

11003 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
11005 * bin/autoreconf.in (parse_args): Do not pass --no-force to
11006 Automake versions prior to 1.8.

11019 Version 2.57b.
11021 * Makefile.cfg (local-checks-to-skip): New.
11022 * Makefile.maint (local-check): Rename as...
11023 (local-checks-available): this.
11024 (local-check): New.
11026 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
11027 * configure.ac: Require Automake 1.7.6.
11029 2003-08-22 Akim Demaille <akim@epita.fr>
11031 Output stack traces in warnings.
11033 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
11034 Replace the former...
11035 (m4_warn): Pass the call stack to _m4_warn.
11036 * bin/autom4te.in: Adjust to output the call stack.
11037 * tests/m4sugar.at (m4@&t@_warn): Adjust.
11039 2003-08-22 Akim Demaille <akim@epita.fr>
11041 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
11042 * bin/autom4te.in: Adjust.
11044 2003-08-21 Akim Demaille <akim@epita.fr>
11046 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
11047 (&verbose): Remove.
11048 (&getopt): Adjust the note and verb channels, depending upon
11049 --verbose.
11050 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
11051 * bin/autoupdate.in: Adjust.
11052 Use &verb, not &verbose.
11054 2003-08-21 Akim Demaille <akim@epita.fr>
11056 * bin/autoheader.in (&parse_args): Use &parse_warnings and
11057 &parse_WARNINGS.
11058 ($help): Use Autom4te::ChannelDefs::usage.
11059 * bin/autoscan.in: Use Autom4te::ChannelDefs.
11060 * lib/Autom4te/General.pm: Don't export error: you don't own it.
11062 2003-08-21 Akim Demaille <akim@epita.fr>
11064 First stab at preserving warnings between calls to autom4te,
11065 including when the cache is used.
11067 There are still several issues: (i) there are too many runs of m4
11068 (one for include, one for warnings, and some more), (ii) warnings
11069 spreading on several lines are not handled gracefully, (iii) the
11070 code meant to have the call stack display for errors does not work
11071 (its handling should move from m4 to autom4te).
11073 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11074 Use them.
11075 (@preselect): Add m4_warn.
11076 ($exit_status): Remove, use $exit_code.
11077 ($help): Use Autom4te::ChannelDefs::usage.
11078 (&handle_m4): No longer define the m4_warnings.
11079 At each run, extract and report the warnings.
11080 Always cache the result, including if the exit status is on
11081 failure, since if nothing changes, we should result in the same
11082 failure, hence we can use the cache.
11083 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11084 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11085 Remove.
11086 (m4_warn): Redefine as a do-nothing: it is its invocation that
11087 matters, as warnings are now reported via traces.
11088 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11089 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11090 the latter reveals calls to the former.
11092 Adjust the tests.
11094 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
11096 2003-08-21 Akim Demaille <akim@epita.fr>
11098 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
11099 Use them.
11101 2003-08-21 Akim Demaille <akim@epita.fr>
11103 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
11104 forward order.
11105 * lib/Autom4te/ChannelDefs.pm: Doc typos.
11106 (&parse_warnings): Accept a list of warning requests.
11107 (&usage): Return a string, not a side effect.
11108 (cross): New warning category.
11110 2003-08-21 Akim Demaille <akim@epita.fr>
11112 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
11113 (&require_configure_ac): Accept an optional directory argument.
11114 ($configure_ac): Remove.
11115 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
11116 (&catfile): Remove.
11117 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
11118 * bin/autoscan.in: Adjust.
11120 2003-08-20 Akim Demaille <akim@epita.fr>
11122 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
11123 Reported by Alexandre Duret-Lutz.
11125 2003-08-20 Akim Demaille <akim@epita.fr>
11127 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11128 * bin/autom4te: Adjust.
11129 In particular, be Autoconf tools are really silent when properly
11130 working, bind the verbosity of the 'note' channel to $verbose.
11131 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11132 (&xsystem, &contents): Remove, since they are exported by...
11133 * lib/Autom4te/FileUtils.pm: this.
11134 More perldoc.
11135 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
11136 * lib/Autom4te/FileUtils.pm: here.
11138 2003-08-20 Akim Demaille <akim@epita.fr>
11140 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
11141 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
11142 from CVS Automake.
11144 2003-08-20 Akim Demaille <akim@epita.fr>
11146 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
11147 (autom4te-update): New.
11148 * Makefile.cfg (update): Bind autom4te-update.
11150 2003-08-19 Derek Price <derek@ximbiot.com>
11152 * lib/autotest/general.m4: Comment various HELP_* diversions.
11153 (PARSE_ARGS_BEGIN): New section for option parsing related
11154 initialization.

11156 package specific options and associated help.

11170 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
11172 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

11174 * doc/autoconf.texi (autom4te Invocation): Mention
11175 Autoconf-without-aclocal-m4.
11177 2003-08-18 Derek Price <derek@ximbiot.com>
11179 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
11180 RUN-IF-PASS optional arguments.

11189 STDOUT & STDERR arguments.
11191 2003-08-14 Derek Price <derek@ximbiot.com>
11193 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
11194 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
11195 shorter column three. Add DESCRIPTION to log file content.
11197 2003-08-13 Derek Price <derek@ximbiot.com>
11199 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
11200 output.
11202 2003-08-12 Derek Price <derek@ximbiot.com>
11204 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
11205 (AT_CHECK_NOESCAPE): Move core functionality to...
11206 (_AT_CHECK): ...this new macro.
11208 2003-08-07 Derek Price <derek@ximbiot.com>
11210 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
11211 (AT_CHECK_NOESCAPE): ...to this new macro.
11213 2003-07-31 Paul Eggert <eggert@twinsun.com>
11215 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
11216 in Bash 2.01. Problem reported by Brian Gough in
11217 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
11219 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
11221 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
11222 -lcrt1.o, for OS X. (trivial change)
11224 2003-07-07 Paul Eggert <eggert@twinsun.com>
11226 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
11227 inside '#ifndef __cplusplus'. Problem reported by
11228 Bob Friesenhahn.
11230 2003-07-06 Bill Clarke <llib@computer.org>
11232 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
11233 'long', not 'int', for benefit of Sun's recent C++ compilers
11234 (trivial change). See:
11235 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
11236 (This really should be 'intptr_t', not 'long', but that would
11237 take more work.)
11239 2003-06-25 Akim Demaille <akim@epita.fr>
11241 * lib/Makefile.am (autom4te.cfg): Make it read only.
11242 Depend on Makefile since it contains substitutions.
11243 From Paolo Bonzini.
11244 * lib/autom4te.in (args): Add local.at? for Autotest args.
11245 This change was made on autom4te.cfg which is generated.
11246 Reported by Raja R. Harinath.
11248 2003-06-25 Akim Demaille <akim@epita.fr>
11250 * doc/autoconf.texi (Header Portability): sys/mount.h.
11251 From Gareth McCaughan.
11253 2003-06-23 Akim Demaille <akim@epita.fr>
11255 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11256 not all of them. This fixes 1. the fact that when testing
11257 Autoconf there are many many config.log, 2. the incorrect use of
11258 top_srcdir to find config.log.
11259 Don't mix the detailed output of failed test with the summary of
11260 failures. Rather, append detailed log afterwards.
11262 2003-06-23 Akim Demaille <akim@epita.fr>
11264 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11265 always run: output config.log on $at_group_log.
11267 2003-06-23 Akim Demaille <akim@epita.fr>
11269 * tests/torture.at (#define header templates): Don't use quotes in
11270 C++ comments as it puzzles Emacs' sh font-lock-mode.
11272 2003-06-23 Akim Demaille <akim@epita.fr>
11274 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
11275 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
11276 * tests/atspecific.m4: Rename as...
11277 * tests/local.at: This.
11278 * tests/suite.at: Move the globals into...
11279 * tests/local.at: here.
11280 * tests/Makefile.am: Adjust.
11281 * doc/autoconf.texi (testsuite Scripts): Adjust.
11283 2003-06-21 Kevin Ryde <user42@zip.com.au>
11285 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
11286 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
11287 ensuring we add -std1 for full-ANSI.
11289 * doc/autoconf.texi (hdrindex): New macro.
11290 Add index entries for portability of various standard header files.
11292 2003-06-20 Akim Demaille <akim@epita.fr>
11294 * configure.ac: Bump to 2.57b.
11296 2003-06-20 Akim Demaille <akim@epita.fr>
11298 Version 2.57a.
11300 2003-06-20 Akim Demaille <akim@epita.fr>
11302 * bin/autom4te.in: Don't rely on $HOME being defined.
11303 Reported by Marc Espie as PR/233.
11305 2003-06-20 Akim Demaille <akim@epita.fr>
11307 * lib/autotest/general.m4: Use at_times_file only if used.
11308 From Nicolas Joly.
11310 2003-06-20 Akim Demaille <akim@epita.fr>
11312 * config/config.guess, config/config.sub, config/elisp-comp,
11313 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
11314 Update from masters.
11316 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
11318 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
11319 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
11320 (TEST_SCRIPT): New diversion.
11321 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
11322 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11323 (AT_INIT): Support for expected failures.
11325 2003-06-02 Akim Demaille <akim@epita.fr>
11327 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
11328 changes.
11329 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
11330 Autoconf nor Automake.
11331 (&contents): New, from Automake.
11332 PODify.
11334 2003-05-28 Paul Eggert <eggert@twinsun.com>
11336 * NEWS, doc/autoconf.texi (Particular Functions),
11337 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11338 is the inverse of localtime.
11340 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
11342 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11343 (handle_exec_errors): New function. Work around $! being
11344 altered by WEXITSTATUS.
11345 (xqx, xsystem): Use handle_exec_errors.
11347 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11349 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11350 Do not call `_exit()', simply modify `$?'.
11351 (xsystem): Reset $! before running system, and check it afterward.
11352 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11353 63 for version mismatches.
11355 2003-05-23 Akim Demaille <akim@epita.fr>
11357 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11358 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11359 the middle of a line).
11360 * lib/m4sugar/m4sugar.m4: Likewise.
11361 Remove useless spaces in comments.
11363 2003-05-23 Akim Demaille <akim@epita.fr>
11365 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11366 exit 63, so that we (or Automake's "missing") can tell the
11367 difference with a plain failure.
11368 * doc/autoconf.texi (Notices): Adjust.
11370 2003-05-23 Akim Demaille <akim@epita.fr>
11372 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11373 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
11374 White spaces cleanup.
11376 2003-05-22 Jim Meyering <jim@meyering.net>
11377 Paul Eggert <eggert@twinsun.com>
11379 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11380 Remove `#include <stdlib.h>' from the list; we should never
11381 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11382 resulting namespace pollution would cause other tests to fail.
11383 Configure scripts run with some older versions of g++ and HP's
11384 aCC would fail due to such an #include. Problems reported by
11385 Matthew Mueller in <http://bugs.debian.org/120704> and by
11386 Keith Bostic in
11387 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11388 In the test, use the test declaration before including <stdlib.h>,
11389 as that's closer to how it'll be used.
11391 2003-05-23 Akim Demaille <akim@epita.fr>
11393 * doc/autoconf.texi (Header Portability): ucred.h.
11394 From Ian Redfern.
11396 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11398 Overhaul Autotest's logging: generate separate log files
11399 in testsuite.dir/NNN/testsuite.log, and append them to
11400 testsuite.log instead of re-running the test verbosely.
11402 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11403 file descriptor, write 0 to at_status_file instead of setting
11404 at_status=0, initialize some new variables (at_status_file,
11405 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11406 to rerun the tests, instead append the at_group_log to the
11407 at_suite_log when a test fails.
11408 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11409 with the AS_MESSAGE_LOG_FD redirected to stdout.
11410 (AT_CLEANUP): save the output status in $at_status_file
11411 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11412 its original place.
11413 (AT_CHECK): since tests are run with a redirected stdout,
11414 and used to be re-run in verbose mode, turn some $at_verbose
11415 into echo, and don't redirect the output of testing stdout
11416 and stderr.
11418 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11419 the name of the debugging directory and information about
11420 its contents.
11422 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11424 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
11425 parameter.

11454 Reported by Jim Meyering.
11456 2003-05-22 Akim Demaille <akim@epita.fr>
11458 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

11539 2003-05-06 Akim Demaille <akim@epita.fr>
11541 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
11542 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11543 by aclocal.m4 is changed it might require the importing of another
11544 m4 extension file, i.e., aclocal must be run.
11546 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11547 (&parse_args): Use --force with aclocal if required and supported.

11561 2003-04-29 Derek Price <derek@ximbiot.com>
11563 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
11564 seperator with m4_append_uniq(). It doesn't work.
11565 (AT_CLEANUP): Add `;' to end of at_help_all.
11566 (AT_INIT): Allow --keywords to be specified more than once. When
11567 grepping $at_help_all for keywords, use the field and keyword
11568 seperators to ensure a complete keyword match. Alter at_prev handling
11569 to support the new --keywords behavior.
11571 2003-04-27 Karl Berry <karl@freefriends.org>
11573 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11574 align better with others. I also made some of the individual
11575 entries on one line, for brevity and to make it easier for me to
11576 sort my dir-example file in the Texinfo distribution :).

11647 * tests/torture.at (Configuring subdirectories): Require aclocal
11648 1.4, otherwise the test fails, as it does support configure.ac.

11681 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
11682 sense. Verbosify the diversion definitions comment.
11684 2003-03-26 Derek Price <derek@ximbiot.com>
11686 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

11722 (Automake): Automake 1.5+ no longer requires special tools to be
11723 present on the developer's host.

11741 ${ac_make}.
11743 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
11744 When constructing paths with IFS=:, quote the path. If we're
11745 constructing a DOS-style absolute path, we don't want to split it
11746 on the colon.
11748 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
11749 in description.
11751 2003-02-25 Pavel Roskin <proski@gnu.org>
11753 * bin/autoheader.in: Add missing newline when printing
11754 suggestion how change AC_DEFINE call.
11756 2003-02-24 Paul Eggert <eggert@twinsun.com>
11758 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix typo in
11759 2002-09-01 patch by replacing "test -n" with "test -z".

11763 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
11764 to fix a mismatch between example and discussion.
11766 2003-02-24 Kevin Ryde <user42@zip.com.au>
11768 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
11769 format starting with "-".
11771 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11773 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
11774 is not portable inside Makefile.
11776 2003-02-20 Akim Demaille <akim@epita.fr>
11778 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
11779 compiler says yeah, but preproc says nope, compiler is right.
11780 Conversely, prompt the reader to send a bug report to the
11781 maintainers of the package, not of Autoconf.
11783 2003-02-20 Klee Dienes <kdienes@apple.com>
11785 * bin/autoreconf.in (autoreconf_current_directory): Properly

11796 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11797 innocuous variant befor including <limits.h> or <assert.h>. This
11798 works around a bug reported by Albert Chin: HP-UX 11i
11799 (and earlier versions) have a <limits.h> that declares
11800 gettimeofday and many other functions.
11802 2002-12-03 Paul Eggert <eggert@twinsun.com>
11804 Version 2.57.
11806 * NEWS, configure.ac: Update version.
11808 * doc/fdl.texi: Upgrade to FDL version 1.2.
11810 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
11811 nontrivially in main's body, so that f's external declaration is
11812 not optimized away in AIX. This should fix the bug reported by
11813 Martin Frydl in
11814 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11816 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11817 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11818 defined, to support freestanding compilers. This should fix the
11819 bug reported by Momchil Velkov in
11820 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11822 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11823 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
11824 obsolete AC_CHECK_TYPE. The missing empty arg was reported
11825 by Simon Josefsson in
11826 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
11828 * Makefile.maint (www-gnu): New macro.
11829 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
11830 the location has moved.
11832 2002-12-02 Martin Frydl <martin@systinet.com>
11834 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
11835 \(.*\) match is too long and there is something more to be checked.
11836 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
11838 2002-11-15 Akim Demaille <akim@epita.fr>
11840 Version 2.56.
11842 * config/install-sh: chmod +x.
11843 From Paul Eggert.
11844 * config/move-if-change: Indenting changes.
11845 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
11846 * configure.ac (AM_INIT_AUTOMAKE): here.
11847 Require 1.7.1.
11849 2002-11-14 Akim Demaille <akim@epita.fr>
11851 Version 2.55.
11853 * config/config.guess, config/config.sub, config/install-sh:
11854 Update from masters.
11856 2002-11-14 Akim Demaille <akim@epita.fr>
11858 * Makefile.maint: Sync with Bison, i.e.:
11859 (po-check): Scan .l and .y files instead of the
11860 .c and the .h files that they generate. This fixes the bug
11861 reported by Tim Van Holder in:
11862 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11863 Look for N_ as well as for _. Try to avoid matching #define for
11864 N_ and _.
11865 From Paul Eggert.
11867 2002-11-14 Akim Demaille <akim@epita.fr>
11869 * doc/autoconf.texi (C Compiler): Compiling several files at once.

11872 2002-11-14 Akim Demaille <akim@epita.fr>

11875 From Paul Eggert and Albert Chin-A-Young.
11877 2002-11-14 Kevin Ryde <user42@zip.com.au>
11879 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
11880 than assigning in main, to avoid HP cc +O3 optimizing it away.
11882 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
11884 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11885 option. Process --recheck after parsing all options. Pass -q
11886 option to configure on --recheck.
11887 (AC_OUTPUT): Pass -q from configure to config.status.
11888 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
11889 arguments to record.
11890 * doc/autoconf.texi (config.status Invocation): Document
11891 config.status -q option.
11893 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
11895 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
11896 Makefile.in if Makefile.am exists.
11897 (output): Strip `.am' from Makefiles. Don't
11898 output AC_CONFIG_FILES if no Makefiles were found.
11900 2002-11-07 Akim Demaille <akim@epita.fr>
11902 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

11907 2002-11-06 Akim Demaille <akim@epita.fr>
11909 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
11910 declaration in extern "C" too.
11911 Reported by Roberto Bagnara.
11913 2002-11-06 Akim Demaille <akim@epita.fr>
11915 * tests/torture.at (Configuring subdirectories): Don't use grep
11916 -w.
11917 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
11918 Reported by Ezra Peisach.
11920 2002-11-05 Akim Demaille <akim@epita.fr>
11922 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11923 Remove.
11924 We _have_ to stop using the old compatibility scheme that tried to
11925 avoid useless backslashes because Libtool 1.4.3 contains a
11926 AC_DEFINE([error_t], [int],
11927 [Define to a type to use for \`error_t' if it is not
11928 otherwise available.])
11929 We _have_ to quote the single quote and backslashes with \. The
11930 old compatibility scheme saw that ` was backslashed, and therefore
11931 did not quote the single quote. Hence before this patch, Autoconf
11932 was not compatible with Libtool.
11934 2002-11-04 Paul Eggert <eggert@twinsun.com>
11936 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

12323 Reported by Alexandre Duret-Lutz.
12325 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12329 (&freeze): Use &error.
12330 (&up_to_date): If a file that was included according to the cache
12331 is no longer there, then the output is out dated.

12344 format, so that Emacs' compile mode understands us.
12345 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12346 if some file was changed instead of `print'.
12347 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

12386 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12387 aclocal invocation, as Gettext macros might not be visible to
12388 aclocal.
12389 Instead of blindly running autopoint, scan configure.ac (not the
12390 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
12391 Reported by Paul D. Smith.
12393 2002-10-08 Paul Eggert <eggert@twinsun.com>
12395 Work around problems found when POSIXLY_CORRECT=1 is set.
12396 None of this seems to have anything to do with POSIX, really,
12397 but it's how Perl getopt works.

12399 "permute", too.

12414 2002-09-28 Akim Demaille <akim@epita.fr>
12416 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
12417 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
12418 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12419 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12421 2002-09-28 Akim Demaille <akim@epita.fr>
12423 * tests/torture.at (Configuring subdirectories): Be robust to
12424 users who use config.site to require for a cache: in this case,
12425 the two last configure runs, using two different sets of
12426 arguments, trigger a legitimate error.
12428 2002-09-28 Akim Demaille <akim@epita.fr>
12430 * tests/m4sh.at (Functions Support, Functions and return Support):
12431 New.
12433 2002-09-28 Akim Demaille <akim@epita.fr>
12435 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12436 autoheader are Perl programs.
12437 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12438 (autom4te): Specify that the sources are in the $srcdir.
12439 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12441 2002-09-28 Akim Demaille <akim@epita.fr>

12444 (tm_zone): Move their rules to...
12445 * lib/autoconf/types.m4: here, using AN_ macros.
12446 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12447 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12448 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
12449 * lib/autoconf/programs.m4: here.
12450 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
12451 (ETAGS_FOR_AUTOCONF): New.
12452 Use it.
12454 2002-09-28 Akim Demaille <akim@epita.fr>
12456 * lib/autoconf/autoscan.m4: New file.
12457 * lib/autoconf/autoconf.m4: Include it.
12458 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12459 that were listed in the original autoscan.list.
12460 * lib/autoconf/headers.m4: Similarly with headers.
12461 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12462 (.m4.m4f): Don't pass --prepend-include, since that's done by
12463 tests/autom4te itself.
12464 * lib/autoscan/Makefile.am: Include freeze.mk.
12465 (autoscan.list): New target --this file is no longer a source.
12466 (autoscan.pre): New file.
12468 2002-09-28 Akim Demaille <akim@epita.fr>
12470 * bin/autoscan.in (@kinds): Make them singular.
12471 Adjust all uses.
12472 (&init_tables): When --debug, report the list of rules to ease
12473 tracking changes in autoscan.list.
12474 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12476 2002-09-28 Akim Demaille <akim@epita.fr>
12478 * lib/autoscan/functions, lib/autoscan/headers,
12479 * lib/autoscan/identifiers, lib/autoscan/makevars,
12480 * lib/autoscan/programs: Merge into...
12481 * lib/autoscan/autoscan.list: this.
12482 * bin/autoscan.in (&init_tables): Adjust.
12484 2002-09-28 Akim Demaille <akim@epita.fr>
12486 * lib/autoscan/functions, lib/autoscan/headers,
12487 * lib/autoscan/identifiers, lib/autoscan/makevars,
12488 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12489 `functions' line is now prefixed with `function:'.
12490 * bin/autoscan.in (&init_tables): Adjust.
12492 2002-09-28 Akim Demaille <akim@epita.fr>
12494 From now on, autoscan files must always map a macro name to a
12495 word: there is no `default' macro for autoscan.
12497 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12498 all.
12499 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12500 explicit.
12502 2002-09-28 Akim Demaille <akim@epita.fr>
12504 * bin/autoscan.in (%c_keywords): Remove.
12505 (&used): Keep only track of the words we might be interested in.
12506 (&output_kind): It is no longer needed to look for non active
12507 checks.
12509 2002-09-27 Akim Demaille <akim@epita.fr>
12511 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12512 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12513 * lib/autoscan/functions: Adjust.
12514 * doc/autoconf.texi (Particular Functions): Adjust.
12516 2002-09-27 Akim Demaille <akim@epita.fr>
12518 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
12519 from /tmp.
12520 Thanks to Bill Moseley and Paul Eggert.
12521 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12522 the tmpdir must be created.
12523 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12524 dir be in the build tree, instead of $TMPDIR.
12526 2002-09-27 Akim Demaille <akim@epita.fr>
12528 * bin/autoscan.in: Improve the comments.
12529 (&parse_args): Drop obsolete undocumented options.
12530 (&output_kind): Output warnings.
12531 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
12532 (getwd): Trigger a warning.
12534 2002-09-26 Akim Demaille <akim@epita.fr>
12536 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12537 Reported by Ralf Corsepius.
12538 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12540 2002-09-26 Akim Demaille <akim@epita.fr>
12542 Single suffix rules and seperated dependencies are not portable.
12544 * doc/autoconf.texi (Installation Directory Variables): Update.
12545 (Limitations of Make): Some about `Single Suffix Rules and
12546 Separated Dependencies'.
12547 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12548 (ifnames, autoscan, autom4te): Un-factor into several rules.
12550 2002-09-25 Paul Eggert <eggert@twinsun.com>
12552 * BUGS (Interoperability bugs): New section. Mention libtool
12553 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12555 2002-09-24 Paul Eggert <eggert@twinsun.com>
12557 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12558 make handles suffix-rules differently from GNU make.
12560 * bin/Makefile.am (SUFFIXES, .in): Remove.
12561 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12562 Move the body of the old .in rule here.
12564 2002-09-16 Akim Demaille <akim@epita.fr>
12566 i960 compilers create `b.out' files by default.
12567 Reported by Ralf Corsepius.
12569 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12570 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12572 2002-09-13 Paul Eggert <eggert@twinsun.com>
12574 * doc/autoconf.texi (Particular Headers): Remove obsolete
12575 reference to `struct timezone' in the description of
12576 AC_HEADER_TIME.
12578 2002-09-13 Akim Demaille <akim@epita.fr>
12580 Version 2.54.
12582 * config/config.sub, config/config.guess: Update.
12583 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12584 * Makefile.am: Adjust.
12586 2002-09-13 Akim Demaille <akim@epita.fr>
12588 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12589 reading config.log when the compiler is rejected.
12590 Suggested by Guido Draheim.
12592 2002-09-13 Akim Demaille <akim@epita.fr>
12594 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12595 (chdir_init) might hang when stat'ing mounted directories.
12596 Reported by Vance Shipley.
12598 2002-09-12 Akim Demaille <akim@epita.fr>
12600 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12601 the lists.
12603 2002-09-12 Akim Demaille <akim@epita.fr>
12605 * doc/autoconf.texi (Defining Symbols): Present two different
12606 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12607 difference between 1 argument calls, and 2-3 argument calls.
12609 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12611 * doc/autoconf.texi: Review grammar and punctuation.
12613 2002-09-11 Paul Eggert <eggert@twinsun.com>
12615 * doc/autoconf.texi: Fix minor formatting, spelling, and
12616 grammatical typos.
12617 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12618 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12619 is obsolescent.
12621 2002-09-11 Akim Demaille <akim@epita.fr>
12623 * doc/autoconf.texi (Questions): Rename as...
12624 (FAQ): this.
12625 (Defining Directories): New.
12627 2002-09-09 Akim Demaille <akim@epita.fr>
12629 * doc/autoconf.texi (Making testsuite Scripts): Update.
12630 Suggested by Nishio Futoshi.
12632 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12634 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12635 plain `@' is wanted.
12637 2002-09-09 Akim Demaille <akim@epita.fr>
12639 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12640 `duplicates', since the algorithm was too naive and could keep
12641 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12642 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12643 Reported by Ralf Corsepius.
12644 * tests/torture.at (Configuring subdirectories): Exercise these
12645 cases.
12647 2002-09-09 Akim Demaille <akim@epita.fr>
12649 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12650 looking for a replacement file.
12651 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12652 directory is relative.
12653 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12654 directory definition.
12655 Reported by Andreas Schwab and Jim Meyering.
12657 2002-09-06 Akim Demaille <akim@epita.fr>
12659 * doc/autoconf.texi (Setting Output Variables): Clarify what
12660 precious variables are.
12661 Suggested by Pontus Skoeld.
12663 2002-09-05 Akim Demaille <akim@epita.fr>
12665 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12666 (ifnames, autoscan, autom4te): Since we don't only depend on
12667 configure.ac variables (such as VERSION etc.), but also on prefix
12668 and so forth, depend on Makefile, not configure.ac.
12669 Reported by Alexandre Duret-Lutz.
12670 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12672 2002-09-05 Kevin Ryde <user42@zip.com.au>
12674 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12675 doesn't seem to be confined to ia64, just say "some versions".
12677 2002-09-04 Akim Demaille <akim@epita.fr>
12679 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12680 Automake 1.6c.
12681 * Makefile.am (maintainer-clean-local): Remove.
12682 (MAINTAINERCLEANFILES): Remove COPYING.
12684 2002-09-03 Paul Eggert <eggert@twinsun.com>
12686 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12687 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12688 Brinkmann.
12690 2002-09-03 Akim Demaille <akim@epita.fr>
12692 * configure.ac: Bump to 2.53d.
12693 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12694 as of today, on Automake's team suggestion.
12696 2002-09-03 Akim Demaille <akim@epita.fr>
12698 Version 2.53c.
12700 2002-09-02 Akim Demaille <akim@epita.fr>
12702 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12703 SITE_MACRO_DIR.
12704 * configure.ac: Disable SITE_MACRO_DIR.
12706 2002-09-02 Jim Meyering <meyering@lucent.com>
12708 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12709 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12710 Also, tweak grammar: s/make sure to/be sure to/.
12712 2002-09-02 Paul Eggert <eggert@twinsun.com>
12714 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12715 directory names are generally preferable to physical names.
12717 2002-09-02 Akim Demaille <akim@epita.fr>
12719 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12720 Reported by Raja R. Harinath.
12721 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12722 * bin/autoupdate.in: Use error instead of die.
12724 2002-09-01 Paul Eggert <eggert@twinsun.com>
12726 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12727 ordinary shell concatenation rather than echo+tr+sed command that
12728 runs afoul of a long-line-related sed bug in Solaris 8.
12730 * bin/autoheader.in (parse_args): --warning -> --warnings.
12732 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12733 stdout, as traditional "ls" does.
12734 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12735 _AC_COMPILER_EXEEXT_O): Likewise.
12736 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12738 * bin/autoconf.as: Add --prepend-include option. This patch was
12739 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12740 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12742 * bin/autoconf.in, configure: Regenerate.
12744 * doc/autoconf.texi (Special Shell Variables): Mention
12745 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12747 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12748 MAILPATH and set PS1, PS2, PS4 to default values, to work
12749 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12750 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12751 the Autoconf documentation specifies; fall back to "unset" only if
12752 this fails. Use a shell for-loop for this rather than an m4 loop,
12753 to shorten the output script.
12755 2002-08-30 Paul Eggert <eggert@twinsun.com>
12757 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12758 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12759 for the CDPATH problem. Document PWD.
12760 (Limitations of Builtins): Document the problem that "cd $foo" and
12761 "ls $foo" may refer to different directories in shells conforming
12762 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12763 example, since the old example is now out of date.
12765 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12766 FOO" and "ls FOO" talk about different directories; this catches
12767 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12768 spaghetti.
12770 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12771 of rolling our own unset.
12772 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12773 in practice we needn't worry about CDPATH if unset doesn't work.
12775 * Makefile.in, aclocal.m4, bin/Makefile.in,
12776 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12777 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12778 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12779 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12780 tests/Makefile.in: Regenerate with Automake 1.6.3.
12782 * config/config.guess, config/config.sub, config/mkinstalldirs:
12783 Update.
12785 * configure: Regenerate with self.
12787 2002-08-30 Kevin Ryde <user42@zip.com.au>
12789 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12790 default output.
12792 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12794 * bin/autom4te.in (Request::load): Correctly test for "do" read
12795 failure.
12797 2002-08-29 Akim Demaille <akim@epita.fr>
12799 * lib/Autom4te/General.pm (&xqx): New.
12800 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12801 hand, which is not portable.
12802 (&error): New.
12803 * bin/autom4te.in: Use them.
12804 Use &error instead of die.
12805 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12806 Adjust.
12808 2002-08-17 Paul Eggert <eggert@twinsun.com>
12810 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12811 default list of compilers to try, since it was long ago superseded
12812 by the ksh fc builtin. Suggested by Steven G. Johnson.
12814 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12816 * doc/autoconf.texi (Invoking autom4te): End the option table,
12817 fixing a bug introduced by the previous patch.
12818 (Limitations of Make): Add a 'target lookup' subentry in the
12819 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12821 2002-07-29 Mark D. Roth <roth@feep.net>
12823 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12824 options and use $AUTOM4TE_PATH.
12825 * doc/autoconf.texi: Remove documentation of autom4te
12826 --include-envvar and --site-macro-subdir options and document
12827 use of $AUTOM4TE_PATH.
12828 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12829 arguments from each language section.
12831 2002-07-29 Paul Eggert <eggert@twinsun.com>
12833 * doc/install.texi: Include copyright symbol in copyright notice.
12835 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12836 Replace with:
12837 (AM_MAKEINFOFLAGS): New macro.
12838 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12839 * Makefile.am (INSTALL): Use the new macros.
12840 Use -o rather than --output, since "missing" does not grok --output.
12842 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12844 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12845 comments do not always work. Never trust the exit status of
12846 `make -k'.
12848 2002-07-24 Kevin Ryde <user42@zip.com.au>
12850 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12851 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12853 2002-07-23 Paul Eggert <eggert@twinsun.com>
12855 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12856 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12857 apparently treats PATH="nonexistent" as if it contained ".".
12858 Bug reported by Stefan `Sec' Zehl.
12860 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12862 * doc/autoconf.texi (Limitations of Make): Mention the special
12863 handling of the obj/ directory by BSD make.
12865 2002-07-20 Kevin Ryde <user42@zip.com.au>
12867 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
12868 backslashes.
12870 2002-07-19 Akim Demaille <akim@epita.fr>
12872 * doc/autoconf.texi (Function Portability): `exit'.
12873 (Programming in M4sh): Ethymology of M4sh.
12875 2002-07-19 Akim Demaille <akim@epita.fr>
12877 * doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): More about $U.
12879 2002-07-18 Akim Demaille <akim@epita.fr>
12881 Version 2.53b.

12989 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
12991 * tests/mktests.sh: Use grep instead of fgrep, as per
12992 "Limitations of Builtins".
12994 2002-06-15 Paul Eggert <eggert@twinsun.com>
12996 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
12997 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
12998 so that we consistently test the just-built programs.
12999 * tests/wrappl.as: Likewise.

13019 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
13021 * bin/autom4te.in ($cache): Don't define using `$me', the name

13053 Suggested by Adam J. Richter.
13055 2002-06-07 Akim Demaille <akim@epita.fr>
13057 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
13058 ac_config_libobj_dir.
13059 (AC_CONFIG_LIBOBJ_DIR): New.
13060 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
13061 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.

13068 * tests/mktests.sh (ac_exclude_list): Don't check

13107 * NEWS, doc/autoconf.texi (Particular Types): Document it.
13108 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it

13114 version of Autoconf that is discussed.
13116 2002-05-22 Paul Eggert <eggert@twinsun.com>
13118 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
13119 from the default list of compilers to try. Suggested by
13120 Kate Hedstrom.
13121 * NEWS: Document the above.
13122 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
13124 2002-05-17 Paul Eggert <eggert@twinsun.com>
13126 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
13127 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
13128 This improves on an earlier suggestion by H. Peter Anvin.
13130 2002-05-16 Paul Eggert <eggert@twinsun.com>
13132 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13133 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13134 Both macros now accept an optional source-dir arg.
13135 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13137 * NEWS: Document this.
13138 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13140 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13141 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13142 not for GNU extensions; this undoes part of the 2000-11-03 change,
13143 reverting to 2.13-compatible behavior.
13144 Add new optional argument DIR.
13145 (AC_FUNC_FNMATCH_GNU): New macro.
13147 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
13149 2002-05-08 Paul Eggert <eggert@twinsun.com>
13151 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13152 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13153 and it causes a 'test' syntax error if it fails.
13154 Bug reported by Stephen Gildea.
13156 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13157 If prototypes are supported, use them to check this at compile-time,
13158 instead of trying to check it at run-time. If we must do a run-time
13159 check, assume that setvbuf is standard when cross-compiling, as
13160 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13161 Bug reported by Paul D. Smith.
13163 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13164 argument specifying location of getloadavg.c. This removes a
13165 FIXME. This idea was taken from Jim Meyering's implementation in
13166 textutils.
13167 * doc/autoconf.texi (Particular Functions): Document this.
13168 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13169 that's what the code does; this fixes a bug reported by
13170 Paul D. Smith.
13172 2002-05-03 Akim Demaille <akim@epita.fr>
13174 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13175 autopoint instead of gettextize.
13176 ($uses_alocal): Rename as...
13177 ($uses_aclocal): this.
13178 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13179 Suggested by Bruno Haible.
13181 2002-05-03 Akim Demaille <akim@epita.fr>
13183 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13185 2002-04-29 Paul Eggert <eggert@twinsun.com>
13187 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13188 files to be 1 second older; just set them to be the same time.
13189 Also, sleep 1 second after the first aclocal, to work around
13190 problems with sub-second time stamps on the input files.
13192 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13194 * doc/autoconf.texi: Mention "set -e -x" lossage
13195 under node "Limitations of Builtins".
13197 2002-04-29 Akim Demaille <akim@epita.fr>
13199 * doc/install.texi: Better wording for setting variables when
13200 running configure.
13201 From Christian Cornelssen.
13203 2002-04-29 Akim Demaille <akim@epita.fr>
13205 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13206 of lack of $LINENO support, then the test will compare the $LINENO
13207 in testsuite vs. the lineno in the test file. This is wrong, of
13208 course.
13209 Be sure to protect it.
13210 Reported by Patrick Welche.
13212 2002-04-25 Akim Demaille <akim@epita.fr>
13214 * doc/autoconf.texi (Obsolete Macros): Typo.
13215 Reported by Vladimir Volovich.
13217 2002-04-25 Akim Demaille <akim@epita.fr>
13219 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13220 than some of the input files, hence, on the second run of aclocal,
13221 if some of its input are younger, make them older.
13222 Suggested by Paul Eggert.
13224 2002-04-25 Akim Demaille <akim@epita.fr>
13226 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
13227 Thanks to Paul Eggert.
13229 2002-04-25 Akim Demaille <akim@epita.fr>
13231 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
13232 and ac_subst_vars be sh variables containing the list of
13233 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13234 DEFAULT diversion.
13235 (_AC_INIT_PREPARE): Use them to log them.
13236 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13237 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13238 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13239 _AC_SUBST_FILES and _AC_SUBST_VARS.
13240 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13242 2002-04-24 Akim Demaille <akim@epita.fr>
13244 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13245 autoheader, so that automake does not complain about a missing
13246 config.h.in that was to be created.
13248 2002-04-23 Akim Demaille <akim@epita.fr>
13250 * bin/autoheader.in (parse_args): --warning takes an argument.
13251 Fixes PR/220.
13253 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
13255 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

13272 2002-04-22 Akim Demaille <akim@epita.fr>
13274 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
13275 Fixes false failures on Darwin.

13300 Minor spelling and grammar fixes.
13302 * doc/autoconf.texi: Follow the outline suggested in the GNU
13303 Sample Texts sections of the Texinfo 4.2 manual. Most
13304 importantly, this makes sure that the copyright notices appear in
13305 all output formats. You probably need Texinfo 4.2 to generate
13306 the manual now.

13345 * doc/autoconf.texi (Shell Substitutions): Explain it.
13346 From Oliver Kiddle and Peter Stephenson.
13348 Have M4sh perform minimal shell sanitizing.
13350 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13351 part into...
13352 (_AS_PREPARE): this new macro.
13353 (AS_PREPARE): New.
13354 (AS_INIT): Invoke AS_SHELL_SANITIZE.
13355 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
13357 Adjust Autoconf and Autotest.
13359 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
13360 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
13361 * lib/autotest/general.m4 (AT_INIT): Likewise.
13362 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
13363 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
13364 AS_SHELL_SANITIZE.
13366 Use this M4sh to generate Autoconf's shell scripts.
13368 * tests/wrapsh.as: New, precursor of wrapsh.in.
13369 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13370 on Autotest and M4sh.
13371 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13372 (wrapsh.in): New target.
13373 * bin/autoconf.as: New, precursor of autoconf.in.
13374 (autoconf.in): New target.
13376 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
13378 * doc/autoconf.texi (Limitations of Make): Mention the issue
13379 with indented comments in rules.
13381 2002-04-09 Andreas Schwab <schwab@suse.de>
13383 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
13384 ac_top_builddir when setting ac_abs_top_builddir.
13386 2002-04-06 Kevin Ryde <user42@zip.com.au>
13388 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
13389 (Portable Shell): Cross reference to Systemology.
13391 2002-04-05 Akim Demaille <akim@epita.fr>
13393 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
13394 directories when descending in a SUBDIRS.
13395 Reported by Ezra Peisach.
13397 2002-04-04 Andreas Schwab <schwab@suse.de>
13399 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13400 contains no literal separators.
13402 2002-04-03 Akim Demaille <akim@epita.fr>
13404 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13405 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13406 Use dnl, not the KILL diversion.
13407 Extracted from...
13408 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13409 (AC_CONFIG_LINKS): here.
13410 Adjust.
13411 Don't use the KILL diversion, as it kills spurious output, which
13412 results in failures being hidden.
13413 Use m4_defn where appropriate.
13414 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13415 after the second argument.
13416 Use m4_defn.
13417 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13418 syntax, as it is provided by M4sugar.
13419 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13421 2002-04-03 Andreas Schwab <schwab@suse.de>
13423 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
13424 expanded if $# <= 2.

13431 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
13432 (_AC_COMPILER_EXEEXT_REJECT): New.
13433 Also recognize *.bb and *.bbg as compilation byproducts.
13434 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
13435 (_AC_COMPILER_OBJEXT): Use them.
13436 Fixes Debian #138666.
13438 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13440 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13442 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13443 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13444 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13445 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13446 (AC_C_CONST): Same.
13447 (AC_C_INLINE): Same.
13448 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
13449 * doc/autoconf.texi, NEWS: Document.
13450 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
13451 AC_C_CROSS.

13455 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
13456 _AS_MKDIR_P_PREPARE.
13458 2002-03-28 Kevin Ryde <user42@zip.com.au>
13460 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13461 to avoid versions of HP C which don't allow that.
13463 2002-03-27 Paul Eggert <eggert@twinsun.com>
13465 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13466 (AS_SHELL_SANITIZE): Invoke it.
13467 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
13469 2002-03-26 Akim Demaille <akim@epita.fr>
13471 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13473 2002-03-26 Akim Demaille <akim@epita.fr>
13475 * doc/autoconf.texi (Introduction): The GNATS base moved.
13477 2002-03-25 Paul Eggert <eggert@twinsun.com>
13479 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13480 as POSIX requires, as it doesn't work with Zsh.
13481 * doc/autoconf.texi (Assignments): Document the problem.
13483 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13485 * doc/autoconf.texi (Limitations of Make): Mention more issue
13486 about VPATH, overriding of macros in sub-makes, and handling of
13487 SHELL.
13489 2002-03-21 Paul Eggert <eggert@twinsun.com>
13491 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13492 problem with here-document buffer boundaries.
13494 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13495 when reinvoking the shell, to work around problems with installers
13496 who put strange things like "cd" commands in their environments.
13498 2002-03-19 Akim Demaille <akim@epita.fr>
13500 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13501 From Aaron Ucko.
13503 2002-03-19 Akim Demaille <akim@epita.fr>
13505 * bin/autoscan.in (scan_file): Specify the location in `&used'
13506 invocations.
13507 From Nicolas Joly.
13509 2002-03-19 Akim Demaille <akim@epita.fr>
13511 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13512 From Nishio Futoshi.
13514 2002-03-19 Akim Demaille <akim@epita.fr>
13516 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
13518 2002-03-18 Paul Eggert <eggert@twinsun.com>
13520 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13521 (Limitations of Usual Tools): Add mkdir section.
13523 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13524 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13525 back on AS_DIRNAME to compute prefixes otherwise; this is
13526 roughly what mkinstalldirs does. That way, we need not have
13527 our own filename disassembler. The old disassembler did not
13528 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13530 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13531 Create at_test_all by a series of assignments,
13532 not by a single assignment of a long string. The latter causes ksh
13533 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13534 presumably because of a buffer overrun.
13536 2002-03-14 Paul Eggert <eggert@twinsun.com>
13538 * lib/autotest/general.m4 (at_times_skip):
13539 Renamed from at_times. Now a boolean.
13540 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13541 says 'times: not found'.
13543 2002-03-14 Akim Demaille <akim@epita.fr>
13545 * bin/autoreconf.in (&study_gettextize): New.
13546 (&autoreconf): Handle newest gettextize.
13547 Rerun aclocal if needed.
13548 Suggested by Andreas Schwab.
13550 2002-03-13 Akim Demaille <akim@epita.fr>
13552 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13554 2002-03-13 Akim Demaille <akim@epita.fr>
13556 * doc/autoconf.texi (Header Portability): New.
13557 Add information about stdint.h and inttypes.h from Paul Eggert.
13559 2002-03-13 Akim Demaille <akim@epita.fr>
13561 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13562 -p'.
13563 From Bob Proulx.
13565 2002-03-12 Akim Demaille <akim@epita.fr>
13567 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13568 m4_require.
13570 2002-03-11 Andreas Schwab <schwab@suse.de>
13572 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13573 does not do it if --with-lispdir is given.
13575 2002-03-08 Akim Demaille <akim@epita.fr>
13577 Version 2.53.
13579 2002-03-08 Akim Demaille <akim@epita.fr>
13581 * doc/autoconf.texi (Subdirectories): Clarify that the
13582 subdirectory should exist.
13584 2002-03-08 Akim Demaille <akim@epita.fr>
13586 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13588 2002-03-08 Akim Demaille <akim@epita.fr>
13590 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13591 aliases the actual variables, and modifications of the former
13592 affect the latter.
13594 2002-03-08 Akim Demaille <akim@epita.fr>
13596 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13597 because of C-c: have m4 output in tmp files, then mv them.
13599 2002-03-08 Akim Demaille <akim@epita.fr>
13601 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13602 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13603 * bin/ifnames.in: Copyright update.
13605 2002-03-08 Akim Demaille <akim@epita.fr>
13607 * doc/autoconf.texi (Invoking autom4te): New.
13609 2002-03-05 Akim Demaille <akim@epita.fr>
13611 * doc/autoconf.texi (Specifying Names): Clarification suggested by
13612 Kevin Ryde.
13614 2002-03-05 Akim Demaille <akim@epita.fr>
13616 Version 2.52i.
13618 2002-03-04 Akim Demaille <akim@epita.fr>
13620 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13621 * lib/autoconf/general.m4 (AC_INIT): More informative error
13622 message for LIBOBJ.
13624 2002-03-04 Akim Demaille <akim@epita.fr>
13626 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13627 parallel builds.
13629 2002-03-04 Akim Demaille <akim@epita.fr>
13631 * doc/autoconf.texi (Transforming Names): Equality between target
13632 and host is irrelevant.
13633 (Specifying Names, Canonicalizing): Remove all references to the
13634 backward compatibility hooks. Rather, collect them all into...
13635 (Hosts and Cross-Compilation): this new section.
13636 * doc/install.texi (System Type): Ditto.
13637 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13638 that `--host' implies cross-compilation.
13640 2002-03-04 Akim Demaille <akim@epita.fr>
13642 * doc/autoconf.texi (Evaluation Macros): New.
13643 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13644 useless.
13645 (_m4_foreach): Define the variant with immediate evaluation so
13646 that it contains exactly the items, not an expression which
13647 evaluation is the current item.
13648 (m4_re_string, m4_re_word): Don't over quote them.
13650 2002-03-04 Akim Demaille <akim@epita.fr>
13652 Instead of having stacking `shift's evaluated at the end, let
13653 `foreach' loops immediately evaluate them.
13655 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13656 $*. This is the n-th time I change my mind, but hopefully this is
13657 the last...
13658 (m4_lquote): New.
13659 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13660 efficient.
13661 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13662 it was only a hack for m4_text_wrap.
13663 (m4_car2): Remove, replaced by...
13664 (m4_cdr): New.
13665 (_m4_foreach): Adjust.
13666 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13667 m4_bpatsubst for clarification.
13669 2002-03-04 Akim Demaille <akim@epita.fr>
13671 * doc/autoconf.texi (Changequote is Evil): New.
13673 2002-03-03 Kevin Ryde <user42@zip.com.au>
13675 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
13676 on old systems like SunOS.

13684 of messages.
13686 2002-02-28 Akim Demaille <akim@epita.fr>
13688 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
13689 message to be sent.

13698 From Akinori Musha.
13700 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
13702 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
13703 translate \r\n to \n.
13705 2002-02-07 Akim Demaille <akim@epita.fr>
13707 Version 2.52h.
13709 2002-02-07 Akim Demaille <akim@epita.fr>
13711 Fix Autoconf PR/209.
13712 Also reported by Frank Denis.
13714 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13716 2002-02-07 Akim Demaille <akim@epita.fr>
13718 Fix Autoconf PR/207:
13719 AC_PREFIX_PROGRAM fails with dashed program names
13721 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
13722 variable when looking for the prefix program.
13723 Now it also works for shell variables.
13725 2002-02-07 Akim Demaille <akim@epita.fr>
13727 * doc/autoconf.texi (Limitations of Builtins): More about
13728 case/esac.
13730 2002-02-06 Akim Demaille <akim@epita.fr>
13732 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
13733 case/esac, some shells don't support it.
13734 Reported by Zack Weinberg.
13735 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
13737 2002-02-06 Akim Demaille <akim@epita.fr>
13739 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
13740 sure not to introduce newlines in at_groups.
13741 * lib/autotest/Makefile.am (autotest.m4f): Typo.
13743 2002-02-06 Akim Demaille <akim@epita.fr>
13745 * tests/torture.at (Configuring subdirectories): Skip if aclocal
13746 is not available.
13748 2002-02-05 Paul Eggert <eggert@twinsun.com>
13750 * doc/autoconf.texi (Specific Compiler Characteristics):
13751 Describe HP-UX cc bug workaround more accurately.
13752 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
13753 not unsigned long.
13754 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
13755 cross-compilers, too. This undoes some of the most recent change
13756 to this file.
13758 2002-02-05 Akim Demaille <akim@epita.fr>
13760 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
13761 to make sure they are up to date when `check' is run.
13763 2002-02-05 Akim Demaille <akim@epita.fr>
13765 * doc/autoconf.texi (Making testsuite Scripts): Document
13766 package.m4.
13768 2002-02-05 Akim Demaille <akim@epita.fr>
13770 * lib/freeze.mk: New.
13772 2002-02-05 Akim Demaille <akim@epita.fr>
13774 Implement `autom4te --freeze'.
13776 * bin/autom4te.in (&freeze): New.
13777 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
13778 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
13780 2002-02-05 Akim Demaille <akim@epita.fr>
13782 * bin/autom4te.in (&parse_args): Implement `frozen files are
13783 optional are the sum of the previous files on the command line'.
13784 Also, pass `--reload-state=' on them, so...
13785 (handle_m4): don't.
13786 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13787 (M4sh): Rely on M4sugar.
13788 (Autotest, M4sh, M4sugar): Use frozen files.
13790 2002-01-31 Akim Demaille <akim@epita.fr>
13792 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13793 * doc/autoconf.texi (Initializing configure): Adjust.
13795 2002-01-30 Akim Demaille <akim@epita.fr>
13797 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13798 alphanumeric to `-' instead of `_'.
13800 2002-01-30 Akim Demaille <akim@epita.fr>
13802 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13803 for plain code, the other for cross-compilation code. The latter
13804 is now run with GCC only.
13805 * doc/autoconf.texi (Compilers and Preprocessors): New.
13807 2002-01-30 Akim Demaille <akim@epita.fr>
13809 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
13810 values.
13811 * doc/autoconf.texi (Initializing configure): Explain how to
13812 change AC_INIT default values.
13814 2002-01-29 Akim Demaille <akim@epita.fr>
13816 * tests/torture.at (Configuring subdirectories): Use configure.in,
13817 so that aclocal 1.4 works.
13818 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13820 2002-01-28 Akim Demaille <akim@epita.fr>
13822 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13823 needs an argument.
13825 2002-01-28 Akim Demaille <akim@epita.fr>
13827 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13828 AUTOTEST_PATH *after* it was set.
13829 Don't put `.' in the PATH: the user should be precise and `./' if
13830 needed. In addition, given that the test suite does some `cd', if
13831 `.' is in the path, the `tested programs' sections will report
13832 programs found in the test suite's directory, while during the
13833 tests (performed in their own directory), these programs are no
13834 longer visible. In other words, the results is confusing and
13835 useless.
13836 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13838 2002-01-24 Akim Demaille <akim@epita.fr>

13880 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13881 message on invalid options.

13885 2002-01-17 Jim Meyering <meyering@lucent.com>
13887 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

13903 configure.

13905 * tests/Makefile.am (package.m4): New.
13906 EXTRA_DIST it since its a source.
13908 2002-01-06 Akim Demaille <akim@epita.fr>
13910 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13911 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13912 and PACKAGE_BUGREPORT from here...
13913 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13914 arguments.
13915 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13916 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

13918 * tests/tools.at (autoheader): Adjust.

13940 2001-12-14 Akim Demaille <akim@epita.fr>
13942 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13943 trailing files, don't apply `-rf' to files which might not be
13944 created by configure (core, core.*, and *.core), but just `rm -f'.
13945 Suggested by Jonathan Kamens.
13947 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13949 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13951 2001-12-14 Akim Demaille <akim@epita.fr>
13953 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13955 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

13958 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13959 abs_srcdir, top_srcpath to abs_top_srcdir.

13962 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13963 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13965 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13967 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13968 C/Fortran linking on HP/UX, by extracting the Fortran library
13969 search path from the LPATH line in the $F77 -v output.
13971 2001-12-12 Kevin Ryde <user42@zip.com.au>
13973 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13974 forbidden file descriptors table.
13976 2001-11-26 Akim Demaille <akim@epita.fr>
13978 * bin/autoscan.in (%c_keywords): Build it at top level.
13979 Map to 1 in order to simplify its uses.
13981 2001-11-26 Akim Demaille <akim@epita.fr>
13983 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13984 Remove $filepath, useless.
13985 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13986 variables, they are really part of the tokens.
13987 Split the input line on spaces and then look for tokens.
13988 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13989 because of `lex$U.$(OBJEXT)'.
13990 (&scan_files): Use "@list" instead of join.
13991 * doc/Makefile.am (CLEANFILES): Add *.fns.
13993 2001-11-26 Akim Demaille <akim@epita.fr>
13995 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13996 Remove, replaced by...
13997 * tests/wrappl.in: Be common for all the Perl executables.
13998 In particular autoscan and autoheader want -I.
13999 * configure.ac: Adjust.

14002 2001-11-26 Akim Demaille <akim@epita.fr>

14012 (&check_configure_ac): Use long options.
14013 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
14015 2001-11-26 Akim Demaille <akim@epita.fr>
14017 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
14018 Before, having a line containing the opening of a multi line
14019 comment made the whole line be ignored.
14021 2001-11-26 Akim Demaille <akim@epita.fr>
14023 * doc/autoconf.texi (Using an Autotest Test Suite): New.
14024 (testsuite Scripts): Be one of its subsection.
14025 (Autotest Logs): New.
14027 2001-11-26 Akim Demaille <akim@epita.fr>
14029 Test groups are now run two directories deeper.
14031 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
14032 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
14033 at_top_builddir.
14034 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
14035 top_srcdir, builddir and top_builddir.
14036 Use `at_*dir' relatively to the directory containing the
14037 suite, use `*dir' when relatively to the current group dir.
14039 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14041 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14042 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14043 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14044 spelling errors.
14046 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14048 * doc/autoconf.texi (Using System Type): Add an example of `case
14049 $host' usage so people quit using `case $target' everywhere.
14051 2001-11-22 Akim Demaille <akim@epita.fr>
14053 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14054 spotted by Jim Meyering.
14056 2001-11-16 Paul Eggert <eggert@twinsun.com>
14058 This patch implements a `long double' suggestion by Oliver Kiddle.
14060 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14061 static, to catch errors if the value isn't known at compile-time
14062 and the compiler supports dynamic arrays. Change its name from
14063 `_array_' to `test_array' to avoid potential name clashes.
14064 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14065 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14066 better than double. Catch a bug in GCC 2.95.2 x86.
14067 * doc/autoconf.texi (C Compiler): Document the above.
14068 * NEWS: Likewise.
14070 2001-11-13 Akim Demaille <akim@epita.fr>
14072 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14073 hand.
14074 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14076 2001-11-13 Akim Demaille <akim@epita.fr>
14078 * lib/autotest/general.m4 (AT_INIT): After having run the test
14079 group, go back to the initial directory, not to at_suite_dir.
14081 2001-11-13 Akim Demaille <akim@epita.fr>
14083 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14084 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14085 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14086 option.
14087 (AT_CHECK_CONFIGURE): Use absolute paths.
14088 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14089 The problem is still the old one: there is no means in M4 (that I
14090 know about) to create a defining macro, because there is no means
14091 to create `$1' etc., therefore, the defining macro ``swallows''
14092 all the arguments meant to the defined macro.
14094 2001-11-13 Akim Demaille <akim@epita.fr>
14096 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14097 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14098 configure.ac.
14099 * tests/aclocal.m4: Remove, as it is no longer used.
14101 2001-11-13 Akim Demaille <akim@epita.fr>
14103 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14104 variable names when referring to a single test group, or to
14105 `suite' when referring to the whole test suite.
14106 `at_last_test' is removed: m4 compute at_format itself.
14107 (at_stdout, at_stder1, at_stderr): New variables.
14108 (AT_CHECK): Use them.
14110 2001-11-13 Akim Demaille <akim@epita.fr>
14112 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14113 in PATH.
14114 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14115 Do it as soon as a test fails, don't wait till the end of the test
14116 suite.
14117 Don't remove $as_me.[0-9]*, since these files no longer exist.
14119 2001-11-13 Akim Demaille <akim@epita.fr>
14121 * tests/tools.at: Use absolute paths, since we are no longer run
14122 in place.
14124 2001-11-13 Akim Demaille <akim@epita.fr>
14126 Now that tests are running in their own private dir, there is no
14127 need to list the files to remove at the end of tests groups.
14129 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14130 (AT_data_files, at_data_files): Remove.
14131 (AT_CLEANUP, AT_DATA): Simplify.
14132 (AT_INIT): Adjust.
14133 Remove the group dir if !debug && !failed.
14134 * tests/atspecific.m4: Adjust.
14136 2001-11-13 Akim Demaille <akim@epita.fr>
14138 Start a new layout for Autotest: `testsuite' creates
14139 `testsuite.dir' in which the at-check-line etc. files are to be
14140 found, and `testsuite.dir/003' where the test group 3 is run.
14142 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14143 at_check_line_file, at_format, at_test_normalized, at_group_dir
14144 are new variables.
14145 Create the directories.
14146 Use absolute paths for at- files.
14147 (AT_CHECK): Adjust.
14149 2001-11-11 Michael Matz <matz@kde.org>
14151 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14152 (m4_car2): New.
14153 (m4_car): Properly quote arguments.
14155 2001-11-13 Akim Demaille <akim@epita.fr>
14157 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14158 with stricter rules on LIBOBJS.
14160 2001-11-12 Paul Eggert <eggert@twinsun.com>
14162 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14163 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14164 __PROTOTYPES too.
14166 2001-11-12 Akim Demaille <akim@epita.fr>
14168 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14170 2001-11-12 Akim Demaille <akim@epita.fr>
14172 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14173 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14174 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14175 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14176 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14177 specify to what the macro should be defined (typically to 1).
14179 2001-11-12 Akim Demaille <akim@epita.fr>
14181 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14182 From Jim Meyering.
14184 2001-11-12 Akim Demaille <akim@epita.fr>
14186 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14187 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14188 definition used by Automake where LEX is +/- "${missing} lex" and
14189 `missing' itself contains variables.
14191 2001-11-12 Akim Demaille <akim@epita.fr>
14193 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14194 Now that M4sh pushes BODY, the comments were output at the end of
14195 the test suites.
14197 2001-11-08 Akim Demaille <akim@epita.fr>
14199 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14200 that we can trace macros from aclocal.m4.
14201 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14202 obsoleted, and redirect to the former anyway.
14203 Reported by Ralf Corsepius.
14205 2001-11-08 Akim Demaille <akim@epita.fr>
14207 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14208 processed only if present.
14209 * tests/torture.at (Configuring subdirectories): Use autoreconf
14210 instead of successive calls to autoconf.
14211 Add a nonexistent subdirectory to exercise the patch above.
14212 Reported by Ralf Corsepius.
14214 2001-11-08 Kevin Ryde <user42@zip.com.au>
14216 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14217 doesn't accept .S files.
14219 2001-11-07 Akim Demaille <akim@epita.fr>
14221 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

14223 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14224 * bin/autom4te.in (warn_forbidden): New.
14225 (handle_output): Use it.
14226 Read m4_pattern_forbid with messages.
14228 2001-11-05 Akim Demaille <akim@epita.fr>
14230 * bin/autom4te.in (--normalize): Remove.
14231 * lib/autom4te.in: Adjust.
14233 2001-11-05 Akim Demaille <akim@epita.fr>
14235 * tests/Makefile.am (testsuite): Rename this target as...
14236 ($(TESTSUITE)): this.
14237 From Nicolas Joly.
14239 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14241 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14242 the --prefix option, also remove it's argument.
14244 2001-11-05 Akim Demaille <akim@epita.fr>
14246 * doc/autoconf.texi (testsuite Invocation): Update.
14247 (Writing testsuite.at): Update.
14249 2001-11-03 Akim Demaille <akim@epita.fr>
14251 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14253 2001-11-03 Akim Demaille <akim@epita.fr>
14255 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14256 (&file_name_is_absolute): New, wrappers around routines from
14257 File::Spec.
14258 Use and export them.
14259 (&find_configure_ac): Optionally take a directory where to look at.
14260 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14261 the arguments.
14262 Default @ARGV to `.', not find_configure_ac.
14263 (&autoreconf): Argument is a directory.

14270 (@export_forward_subs): New.
14271 Add basename, dirname, and fileparse.
14272 (@EXPORT): Adjust.
14273 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14274 Don't look for aclocal flags if we already know aclocal is not
14275 used.
14276 Move aclocal.m4t only if it exists.
14277 Reported by Ezra Peisach.
14279 2001-11-03 Akim Demaille <akim@epita.fr>
14281 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14282 passed on command line, defaulting to ./configure.ac if present.
14283 (&maybe_autoreconf, File::Find): Remove, unused.
14284 (&autoreconf): If autoconf is not used, don't try to trace.
14286 2001-11-02 Akim Demaille <akim@epita.fr>
14288 * configure.ac: Bump to 2.52g.
14290 2001-11-02 Akim Demaille <akim@epita.fr>
14292 Version 2.52f.
14294 2001-11-02 Akim Demaille <akim@epita.fr>

14302 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14303 Don't run aclocal when aclocal.m4 is not from aclocal.
14304 From Ezra Peisach.
14305 Don't run libtoolize and gettextize if --install is not given.
14307 2001-11-01 Paul Eggert <eggert@twinsun.com>
14309 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14310 be invoked before _AS_LINENO_PREPARE.
14311 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14312 than character ranges.
14314 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14315 invoking AS_BASENAME. Set the locale variables to 'C' if
14316 possible, as POSIX requires this to get the traditional
14317 behavior.
14318 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14320 2001-10-31 Paul Eggert <eggert@twinsun.com>
14322 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14323 with {}, as that triggers a bug in Bash 2.05.
14325 (_AS_LINENO_PREPARE): Use Sed rather than
14326 Awk. Fix the sed prepass to work even if there are multiple
14327 instances of $LINENO on the same line. Do not substitute for
14328 other variables like $LINENOT. Do not check file dates; such a
14329 check is unreliable on sufficiently fast machines, and removing
14330 the check makes the code simpler and more reliable. Check for
14331 output and chmod failures.
14333 * doc/autoconf.texi (Special Shell Variables): Document
14334 the above.
14336 2001-10-31 Akim Demaille <akim@epita.fr>
14338 * tests/Makefile.am (atconfig): Remove this target, Automake
14339 handles it now.
14341 2001-10-31 Akim Demaille <akim@epita.fr>
14343 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14344 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14345 provided, while it is optional.
14346 * configure.ac: Adjust.
14348 2001-10-26 Paul Eggert <eggert@twinsun.com>
14350 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14351 lib/Autom4te/Struct.pm:
14352 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14353 with 5.005_02.
14355 * doc/autoconf.texi (Special Shell Variables): Document some
14356 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14358 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14359 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14360 eval $LINENO is not portable in practice.
14362 2001-10-24 Akim Demaille <akim@epita.fr>
14364 * lib/Autom4te/General.pm (backname): New.
14366 2001-10-24 Akim Demaille <akim@epita.fr>
14368 * m4/: Remove, merged into...
14369 * config/: here.
14371 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14373 * doc/autoconf.texi (Shellology): Mention the problems with bash
14374 2.05's use of ANSI quoting in its `set' builtin.
14376 2001-10-22 Paul Eggert <eggert@twinsun.com>
14378 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14379 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14380 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14381 POSIX decided to standardize on the int flavor of strerror_r.
14382 Always do char* test, as there's no reason not to.
14383 Assign to a char* var, to catch strerror_r that returns int*.
14385 * doc/autoconf.texi (Particular Functions):
14386 Document the above changes. Also, document the fact that
14387 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14389 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14391 2001-10-20 Akim Demaille <akim@epita.fr>
14393 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14394 the executable was missing from the log.

14398 * lib/Autom4te/General.pm (&update_file): If destination is
14399 unchanged, remove the source.
14400 (&up_to_date_p): Don't be verbose, be debug.
14401 * bin/autoreconf.in: No longer support --m4dir.
14402 (&autoreconf): Display the full path of the configure.ac we are
14403 studying.
14404 Trace it only once.
14405 Be sure to honor --force with gettextize.
14406 Always run aclocal.
14407 * doc/autoconf.texi: Adjust.
14409 2001-10-20 Akim Demaille <akim@epita.fr>
14411 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14412 Remove, dead.
14413 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14414 `intl' is already present, as it refuses unless --force.
14415 (&parse_args): Use -I, --include instead of the old Autoconf
14416 options.
14417 ($localdir, $autoconf_dir): Remove.
14418 (@include): New.
14419 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14421 2001-10-19 Jens Petersen <petersen@redhat.com>

14429 file in @configure_input@.
14430 Don't mention `automatically' in addition to `generated'.
14431 * tests/torture.at (#define header templates): Adjust.
14433 2001-10-19 Akim Demaille <akim@epita.fr>
14435 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
14436 comment, explain how to install automatic mode selection.
14437 From Russ Allbery.
14439 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14441 * bin/autoreconf.in (autoreconf): Display the path to the
14442 configure.ac being studied.
14444 2001-10-18 Paul Eggert <eggert@twinsun.com>
14446 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14447 long, to work around a bug in the HP C compiler version HP92453-01
14448 B.11.11.23709.GP.
14450 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14451 (AS_BASENAME_EXPR): New macro.
14452 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14453 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14454 and fall back on 'sed' only if the other two fail. This makes
14455 AS_BASENAME act more like AS_DIRNAME.
14456 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14457 contains white space.
14458 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14459 Use AS_DIRNAME, since I think it's now DOS-friendly.
14460 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14461 Allow "dirname //FOO" to return either / or //, as POSIX allows
14462 either behavior.
14464 2001-10-10 Akim Demaille <akim@epita.fr>
14466 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
14467 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
14468 From Eric Sharkey.
14470 2001-10-10 Akim Demaille <akim@epita.fr>
14472 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14473 m4_define, since...

14512 bother with $force since...
14513 * lib/Autom4te/General.pm: does.
14515 2001-10-08 Akim Demaille <akim@epita.fr>
14517 * bin/autoreconf.in: Rewrite in Perl.
14518 * configure.ac: Adjust.

14591 * tests/tools.at (AT_DATA_FORBIDDEN): New.

14604 ourselves with CONFIG_SHELL.
14606 2001-10-05 Paul Eggert <eggert@twinsun.com>
14608 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
14609 doesn't exist. Remove *.tmp, as a .tmp file is created during the
14610 build of $(TESTSUITE).
14612 2001-10-05 Akim Demaille <akim@epita.fr>
14614 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

14656 instead of exec'ing to preserve $0 and $@.
14658 2001-10-01 Akim Demaille <akim@epita.fr>
14660 * tests/testsuite (AT_INIT) <at_pass_list>: New.

14679 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
14680 Don't use nested parenthesization. This patch was originally
14681 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
14682 but somehow it didn't get incorporated then.
14683 * doc/autoconf.texi (Limitations of Usual Tools):
14684 Clarify remark about sed and nested parenthesization.
14686 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
14687 Report an error if the size cannot be determined even though
14688 the type exists.
14689 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14690 Check for `expr' arithmetic overflow, and for compilation failure,
14691 and invoke a new argument $4 if either is discovered.
14692 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14693 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
14695 2001-09-28 Akim Demaille <akim@epita.fr>

14725 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
14726 (AC_PROG_CPP requires AC_PROG_CC): here and...
14727 * tests/fortran.at (GNU Fortran 77): there.
14728 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14729 AC_TRY_RUN is about compilation, not shell commands.

14734 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
14735 Raja R Harinath:
14736 Be sure to detect when $LINENO always returns the same value.
14737 Look for the original script, basename($0) is certainly not
14738 enough.
14739 Pass the CLI arguments to `$as_me.lineno'.
14741 2001-09-25 Akim Demaille <akim@epita.fr>
14743 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

14836 2001-09-22 Akim Demaille <akim@epita.fr>
14838 Rely on `$LINENO' when possible instead of `__oline__'.
14840 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14841 `$LINENO' support replacement when not supported.
14842 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14843 them explicitly to be sure they are not output before this section

14853 character (u: -> ue) in a code comment.

14884 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14887 arguments. Fixed a typo.
14889 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14891 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

14903 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14905 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14906 already have $file). Set output files to binary mode (helps avoid
14907 CR issues on DOSish systems).
14909 2001-09-19 Akim Demaille <akim@epita.fr>
14911 * lib/autotest/general.m4: Englishoes.
14912 From Tim Van Holder and Alexey Mahotkin.
14914 2001-09-18 Paul Eggert <eggert@twinsun.com>
14916 * doc/autoconf.texi (Common Shell Constructs): New node,
14917 documenting AS_DIRNAME.
14918 (Limitations of Usual Tools): Refer to it when discussing dirname.
14919 Also, update discussion of POSIX standard to reflect latest draft.
14921 * lib/autoconf/c.m4:
14922 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14924 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14925 Do not pass a first argument with leading '-'
14926 to expr, by parenthesizing initial integers that might be negative.
14928 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14929 now merely checks whether it is an error to pass an argument
14930 to getpgrp.
14932 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14933 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14934 whether it is a (compile-time) error to pass an argument to
14935 getpgrp. This simpler test supports the revised documentation,
14936 and is all that AC_FUNC_GETPGRP's users really need.
14938 2001-09-18 Akim Demaille <akim@epita.fr>
14940 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14950 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14951 correctly.
14952 Add test for AS_BASENAME.
14953 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14954 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14955 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14956 * tests/base.at: Fixed the expected responses. The old ones were
14957 one line out...
14958 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14959 the documentation claims it should (and how it behaved in 2.13).
14961 2001-09-18 Akim Demaille <akim@epita.fr>
14963 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14964 the AC_CONFIG_COMMANDS invocation.
14965 This also solves the name clash problems.
14966 Don't set the package's ID.
14967 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14968 No longer to be shipped.
14969 (version.in): Remove.
14970 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14971 * lib/autoconf/status.m4: Adjust.
14972 Use `m4_PACKAGE_STRING'.
14973 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14974 the only optional argument is the name of the test suite.
14975 Expect `package.m4' to define the package signature.
14976 * lib/autom4te.in (Autotest): Add `package.m4?'.
14977 * tests/Makefile.am (package.m4): New.
14978 * tests/suite.at: ifnames is a victim.
14980 2001-09-18 Akim Demaille <akim@epita.fr>
14982 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14983 AC_LIBSOURCE, AC_CONFIG_FILES.
14984 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14985 program version string doesn't match the package's.
14986 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14987 after `(cached)'.

14991 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14992 Allow expression to return any value that can fit into unsigned long
14993 (not int, as before). Check for output errors.
14995 2001-09-17 Bruno Haible <haible@ilog.fr>
14997 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14998 Always include <stdio.h> and <stdlib.h>. Evaluate
14999 the expression in an extra function before these includes. Call
15000 fprintf "%d" only after ensuring the argument is of type 'int'.
15001 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
15003 2001-09-17 Paul Eggert <eggert@twinsun.com>
15005 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
15006 or CFLAGS=-O5. In that case, the linker has a relaxed view of
15007 fatal errors, and AC_CHECK_LIB causes it to include libraries even
15008 when they don't exist.
15010 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
15011 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
15012 need it.
15014 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
15015 version with the version used by fileutils 4.1, except use
15016 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
15017 we don't need it.
15019 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
15021 2001-09-13 Akim Demaille <akim@epita.fr>
15023 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
15024 _first_.
15025 Reported by Gerrit P. Haase.

15029 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

15057 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
15059 2001-09-13 Akim Demaille <akim@epita.fr>
15061 * lib/autotest/general.m4 (AT_INIT): Create and remove
15062 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15063 test suites can cohabit.
15065 2001-09-13 Akim Demaille <akim@epita.fr>
15067 * tests/mktests.sh: Don't output banners for empty test files.
15069 2001-09-13 Akim Demaille <akim@epita.fr>

15119 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

15135 2001-09-07 Akim Demaille <akim@epita.fr>
15137 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
15138 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
15139 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
15140 related variables into `at_package_*'.

15152 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
15153 in addition, it introduces useless differences in logs.
15154 (AT_INIT): Let atconfig and atlocal be both optional.
15155 Adjust PATH computation.

15163 2001-09-05 Akim Demaille <akim@epita.fr>
15165 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
15166 to avoid GCC warnings.
15167 From Uwe Seimet.
15169 2001-09-05 Akim Demaille <akim@epita.fr>
15171 * bin/autom4te.in: --language is -l, not -s.
15173 2001-09-05 Akim Demaille <akim@epita.fr>
15175 Be ready to handle filenames as stupid as `dnl.at', for if even
15176 the maintainer is dumb enough to do that...
15178 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15179 excellence in M4 quotation: consider `__file__' is active.
15181 And BTW, when invoking m4, pass the --include in the right order:

15203 * bin/autoscan.in: Use `getopt' and `find_files' etc.
15204 Add -I, --include support.
15205 * doc/autoconf.texi (autoscan Invocation): Adjust.
15207 2001-09-05 Akim Demaille <akim@epita.fr>
15209 CVS GNU M4 doesn't like `undefine(undefined)'.
15211 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
15212 New, extracted from main.
15213 Use IO::File wherever possible.
15214 (input.m4): Be constant, use -I instead of hard coding $tmp.
15215 Therefore be a quoted heredoc.
15216 Don't invoke `_au_disable', since ac was not loaded, but just
15217 `unm4.m4'.
15219 2001-08-31 Akim Demaille <akim@epita.fr>
15221 Version 2.52d.
15223 2001-08-31 Akim Demaille <akim@epita.fr>
15225 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
15226 previous patch.
15227 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
15229 2001-08-31 Akim Demaille <akim@epita.fr>
15231 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
15232 serious problems handling heredocs in heredocs.
15233 Reported by Nicolas Joly.
15235 2001-08-31 Akim Demaille <akim@epita.fr>
15237 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
15238 (Making testsuite Scripts): Update.
15240 2001-08-31 Akim Demaille <akim@epita.fr>
15242 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
15244 2001-08-31 Akim Demaille <akim@epita.fr>
15246 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
15247 (testsuite Scripts): There is no such thing as `atconfig.in'.
15248 And actually one diagram is missing: test suite runtime.
15250 2001-08-31 Akim Demaille <akim@epita.fr>
15252 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
15253 inverse order.
15255 2001-08-31 Akim Demaille <akim@epita.fr>
15257 * bin/autoupdate.in (@include): `installcheck' revealed the path
15258 to m4sugar was lacking!
15260 2001-08-31 Akim Demaille <akim@epita.fr>
15262 * man/Makefile.am (.x.1): We really have to pass
15263 autom4te_perllibdir.
15265 2001-08-31 Akim Demaille <akim@epita.fr>
15267 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
15268 debug scripts, in particular passing explicitly listed tests to
15269 run is stupid.
15271 2001-08-31 Akim Demaille <akim@epita.fr>
15273 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
15274 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
15275 Use directly autom4te, not autoconf.
15276 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
15278 2001-08-31 Akim Demaille <akim@epita.fr>
15280 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
15281 * bin/autoheader.in (%symbol): Strip arguments of macros.
15283 2001-08-31 Akim Demaille <akim@epita.fr>

15287 2001-08-31 Akim Demaille <akim@epita.fr>
15289 * bin/autom4te.in (&parse_args): Die on unknown languages.
15290 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
15291 need for autoconf.
15292 Promote --include over --macrodir and other obsolete options.
15294 2001-08-31 Akim Demaille <akim@epita.fr>
15296 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
15297 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
15298 * bin/autom4te.in ($autoconf): Pass --force.
15299 `print $out' doesn't print `$_' but `$out'.
15300 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
15301 (autoheader): Pass --force since the test suite goes too fast for
15302 the time stamps.
15303 Adjust to the new autoheader messages.
15305 2001-08-31 Akim Demaille <akim@epita.fr>
15307 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
15308 Check the completeness of the #template.
15309 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
15310 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
15311 invocation.
15313 2001-08-31 Akim Demaille <akim@epita.fr>
15315 * lib/Autom4te/General.pm (&find_file, &update_file): New.
15316 * bin/autoupdate.in, bin/autoheader.in: Adjust.
15317 Drop AC_MACRODIR dead for real.
15318 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15319 `autoheader: `config.hin' is created'.
15320 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15322 2001-08-31 Akim Demaille <akim@epita.fr>
15324 * bin/autoheader.in: Rewrite in Perl.
15325 * tests/autoheader: Adjust.
15327 2001-08-31 Akim Demaille <akim@epita.fr>
15329 * bin/autoconf.in (--include, -I): New option.
15330 Map --localdir, --autoconf-dir onto it.
15331 Forward autom4te's options instead of interpreting them.
15332 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15333 There is no such envvar since the inception of autom4te.cfg.
15334 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15335 * bin/autoupdate.in: Adjust, and perform more control.
15336 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15337 * tests/autoconf: Dittowise.
15339 2001-08-31 Akim Demaille <akim@epita.fr>
15341 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15342 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15343 optionally `FILE'.
15344 Use -e, not -f, since /dev/null for instance is OK.
15345 (&parse_args): Adjust.
15346 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15348 2001-08-31 Akim Demaille <akim@epita.fr>
15350 * configure.ac: Also find tested executables in bin.
15351 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
15352 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
15353 installed peer executables, only PATH is allowed to resolve it.
15354 Pass `autoconf_dir' via options, not via invisible envvars.
15355 * lib/Autom4te/General.pm (&find_peer): Remove.
15356 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15357 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15358 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15359 find the executables for it.
15360 * tests/Makefile.am: Major cleanup. Too lazy to document...
15361 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15362 We only need PERL.
15363 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15364 indeed related to running the test suite, while passing
15365 --autoconf-dir and others is related to running non installed
15366 Autoconf executables. So don't do that, leave it to...
15367 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15368 * tests/autoscan: New.
15369 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15370 refer to library files: rely on --language.
15372 2001-08-29 Akim Demaille <akim@epita.fr>
15374 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
15375 s/--set/--language/.
15377 2001-08-29 Akim Demaille <akim@epita.fr>
15379 * doc/autoconf.texi: Strip the @nodes.
15380 Suggested by Paul Eggert.
15381 (Initializing configure): Typo.
15383 2001-08-29 Akim Demaille <akim@epita.fr>
15385 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15386 Suggested by Paul Eggert.
15388 2001-08-29 Akim Demaille <akim@epita.fr>
15390 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15391 download in a tmp dir.
15393 2001-08-29 Akim Demaille <akim@epita.fr>
15395 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
15396 case insensitive OSes out there :(
15397 From Tim Van Holder.
15399 2001-08-29 Akim Demaille <akim@epita.fr>
15401 * lib/autom4te.in: New.
15402 * lib/Makefile.am (edit, autom4te.cfg): New.
15403 * bin/autom4te.in (BEGIN): Simplify.
15404 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
15405 (&load_configuration): New. Use it.
15406 (&parse_args): Support --mode, --set, and --melt.
15407 * bin/autoconf.in: Simplify and adjust.
15408 * tests/Makefile.am (AUTOMAKE): Use --set.
15409 * tests/atlocal.in: Adjust.
15410 * BUGS: distcheck and check are weak.
15412 2001-08-29 Akim Demaille <akim@epita.fr>
15414 * lib/autotest/general.m4: Use
15415 foo=`(command) 2>/dev/null`
15416 not
15417 foo=`command` 2>/dev/null
15418 (at-devnull): Rename as...
15419 (AT-devnull): this.
15420 (--clean): Remove AT-* files too.
15421 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
15422 Reported by Nicolas Joly.
15424 2001-08-28 Akim Demaille <akim@epita.fr>
15426 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

15432 * doc/autoconf.texi (Function Portability): Mention C right shifts.
15434 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
15436 * lib/autotest/general.m4: Reword some messages.
15437 (AT_INIT): Check for the `times' builtin before using it.
15438 Support test ranges as arguments to the testsuite.
15439 Have -e imply -d as the help text suggested.
15441 2001-08-27 Akim Demaille <akim@epita.fr>
15443 * Makefile.maint: Formatting changes.
15444 (do-po-update, po-update, cvs-update, update): New targets.

15456 * lib/autotest/general.m4 (AT_INIT): Log the command line.
15457 Support `VAR=VAL' as arguments.
15458 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
15459 may be set via the command line.
15461 2001-08-27 Akim Demaille <akim@epita.fr>
15463 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
15464 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
15465 first the build dirs, then the src dirs.

15477 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
15478 `ac_top_builddir' to mimic Automake's vocabulary, which much more
15479 readable.
15480 Adjust callers.
15481 * doc/autoconf.texi (Configuration Actions): Document the vars
15482 available in commands.
15483 Emphasize the risks of collisions in init-cmds.

15488 (Initializing configure): this new node.
15490 2001-08-27 Akim Demaille <akim@epita.fr>

15503 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

15513 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
15514 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
15515 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
15516 -> ac_dir).
15517 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
15518 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
15520 2001-08-27 Akim Demaille <akim@epita.fr>

15546 (AMTAR): Help automake define it.
15547 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
15548 needed, 1.5 can have a macro and a target with the same name.

15550 * m4/strip.m4: New.

15565 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15566 the name of the directory they're in, instead of the filename,
15567 since version.m4 is now in m4sugar, but m4_acversion must not be
15568 classified as an Autoconf macro.
15569 ($input_m4): Don't qualify the path to m4sugar.
15570 Rather, pass autoconf_dir to m4.
15571 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
15572 * tests/suite.at: Require 2.52c.
15574 2001-08-27 Akim Demaille <akim@epita.fr>

15586 of config.log on traps.
15587 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
15588 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
15589 for config.status'.
15590 Open the log as soon as possible.
15591 Use the same log introduction as configure's.
15593 2001-08-22 Paul Eggert <eggert@twinsun.com>
15595 * doc/autoconf.texi (Indices): New node.
15596 Move indices out of the top level menu and into this submenu.
15598 2001-08-22 Akim Demaille <akim@epita.fr>
15600 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use

15653 2001-08-20 Akim Demaille <akim@epita.fr>
15655 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
15656 * NEWS, README, README-alpha, TODO, tests/README: This package is
15657 `Autoconf', not `autoconf' (the executable).
15659 2001-08-20 Akim Demaille <akim@epita.fr>
15661 Info readers seem to need `Index' in the index node title :(
15663 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15664 simplified index node names.
15666 2001-08-20 Akim Demaille <akim@epita.fr>

15706 * tests/Makefile.am: Adjust.
15708 2001-08-20 Akim Demaille <akim@epita.fr>
15710 Huh!?!?! There are still some user EOF tags used, which prevents
15711 their use in AC_CONFIG_COMMANDS for instance...
15713 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15714 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
15715 `_CSEOF', or `_ATEOF', as appropriate.

15725 2001-08-20 Akim Demaille <akim@epita.fr>
15727 Autotest invokes M4sh's initialization.
15729 * lib/autotest/general.m4: Adjust the diversion names.

15775 2001-08-17 Akim Demaille <akim@epita.fr>
15777 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
15778 `$0.log' as for projects where testsuite is in src, we'd have
15779 testsuite.log created in src.

15783 * bin/autom4te.in (&parse_args): Recognize --normalize.

15791 (AC_CHECK_HEADER): Use them.
15793 2001-08-17 Akim Demaille <akim@epita.fr>
15795 * doc/autoconf.texi: Work around Texinfo buglets.
15796 (Transformation Rules): One example is enough, users are expected
15797 to have their brains on. And BTW, use DESTDIR.
15798 (dvar): New macro. Use it.
15800 2001-08-17 Akim Demaille <akim@epita.fr>
15802 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15804 looking for ChangeLogs.
15806 2001-08-17 Akim Demaille <akim@epita.fr>
15808 * bin/autom4te.in: --normalize is a new option.
15809 * bin/autoconf.in: Use it.
15811 2001-08-17 Akim Demaille <akim@epita.fr>
15813 * bin/Makefile.am, lib/Autom4te/Makefile.am, lib/autoconf/Makefile.am

15821 2001-08-15 Akim Demaille <akim@epita.fr>
15823 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
15824 Use it.
15826 2001-08-15 Akim Demaille <akim@epita.fr>
15828 * doc/autoconf.texi (pr): New index.
15829 (prindex, findex): Use, merge, and output them.
15830 (Environment Variable Index, Output Variable Index)

15834 (Autoconf Macros, M4 Macros, Autotest Macros): these.
15835 * doc/install.texi: Use @command.
15836 (Environment Variables): Rename as...
15837 (Defining Variables): this.
15839 2001-08-15 Akim Demaille <akim@epita.fr>
15841 * doc/autoconf.texi (Function Portability): sprintf's return
15842 value.
15843 From Kevin Ryde.
15845 2001-08-15 Akim Demaille <akim@epita.fr>
15847 * Makefile.maint (CVS): New.
15848 (local-check): Run changelog-check. last.
15849 (alpha): Don't depend upon local-check, since...
15850 (cvs-dist): depends upon it.
15852 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15854 * tests/Makefile.am: Use a clean-local rule to remove
15855 autom4te.cache (it's a directory, not a file.
15856 * Makefile.am: Ditto (but maintainer-clean-local).
15858 2001-08-15 Akim Demaille <akim@epita.fr>
15860 * bin/autom4te.in (@m4_warning): New.
15861 (&handle_m4): Use it.
15862 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15863 warnings are issued at each run.
15864 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15865 is in the src tree.
15867 2001-08-15 Akim Demaille <akim@epita.fr>
15869 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15870 don't waste time running `autoupdate --version' works.
15871 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15873 2001-08-13 Akim Demaille <akim@epita.fr>
15875 * doc/autoconf.texi (ma): Rename this index as...
15876 (ac): this.

15889 duration of the test suite.
15891 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15893 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
15894 endianness for comparison instead of relying on AT_CHECK_ENV.
15896 2001-08-11 Paul Eggert <eggert@twinsun.com>
15898 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
15899 to the INSTALL file.
15901 2001-08-11 Paul Eggert <eggert@twinsun.com>

15926 * tests/mktests.sh: Update year in copyright notice.
15928 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15930 * tests/semantics.at (AC_C_BIGENDIAN): New test.
15932 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15934 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15935 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15936 * doc/autoconf.texi (C Compiler Characteristics): Update
15937 documentation for AC_C_BIGENDIAN.
15939 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15941 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15942 magic values from an object file when cross-compiling.
15943 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15945 2001-08-10 Akim Demaille <akim@epita.fr>
15947 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15948 effects.
15949 Suggested by Russ Allbery.
15951 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15953 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15954 current $prefix to the sub-configures.
15956 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15958 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15959 extension (needed on BeOS). Reported by Guido van Rossum.
15961 2001-08-09 Akim Demaille <akim@epita.fr>
15963 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15965 2001-08-07 Akim Demaille <akim@epita.fr>
15967 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15968 removed.
15969 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15970 No need to remove the files before and after the each test, before
15971 each test and at the end of the suite is enough.
15972 Display only the children `times', not the shell's.
15973 If the test failed or was skipped, at-times is not available.
15975 2001-08-07 Akim Demaille <akim@epita.fr>
15977 Always produce testsuite.log, including when there are no
15978 failures. This helps getting information on skipped tests, and
15979 duration of the tests. Err, implement the latter btw.
15981 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15982 Dump information on the first run of each test.
15983 (AT_CLEANUP): Create `at-times' containing the duration of the
15984 test group.
15986 2001-08-07 Akim Demaille <akim@epita.fr>
15988 The use of `dumpstat' revealed that `len' was used although it
15989 should not. m4_text_wrap was using it, but in the Autoconf world
15990 where it is legal. Hence (i) test M4sh in its own world, not
15991 Autoconf's, and (ii), ahem, fix the bug :)
15993 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15994 does not like `' instead of [].
15995 (AT_INIT): Forbid `^_?AT_'.
15996 And don't output such tokens.
15997 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15998 `script.as', and `autom4te.cache'.
15999 Remove `empty' and `macro' which are no longer used.
16000 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
16001 * tests/m4sugar.at: Use it.
16002 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
16004 2001-08-07 Akim Demaille <akim@epita.fr>
16006 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
16008 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
16010 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
16012 2001-08-04 Akim Demaille <akim@epita.fr>
16014 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
16015 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
16016 AC_TRY_LINK.
16017 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
16018 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
16019 (AC_F77_MAIN): Likewise.
16021 2001-08-04 Akim Demaille <akim@epita.fr>
16023 Don't rely on M4sugar outputting the patterns in files, since we
16024 might process the output _without_ running m4, hence without these
16025 files.
16027 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
16028 * bin/autom4te.in (@Request::includes): Remove, unused.
16029 (@Request::source): Rename as...
16030 (@Request::input): this.
16031 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
16032 (&handle_output): Fetch the patterns from the traces.
16033 `$forbidden' and `$allowed' are constant: use m//o.
16034 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
16035 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
16037 2001-08-04 Akim Demaille <akim@epita.fr>
16039 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
16040 autoconf', i.e., in addition to caching traces, cache the output.
16042 * bin/autom4te.in (Request::cache): Rename as...
16043 (Request::id): this.
16044 ($cache, $icache, $tcache, $ocache): New.
16045 (&handle_m4): Save M4 output in the cache instead of $tmp.
16046 (&handle_output): Adjust.
16047 (&up_to_date_p): Check that the output cache is up to date too.
16048 (top level): Run `&handle_m4' iff force or the cache is invalid.
16049 Run `&handle_output' if the output cache is more recent.
16051 2001-08-04 Akim Demaille <akim@epita.fr>
16053 * bin/autom4te.in ($force): New.
16054 (&parse_args, &print_usage): -f, --force is a new option.
16055 (&handle_output): CPP directives might have spaces after `#'.
16056 (&parse_args): The first file only can be frozen.
16058 2001-08-04 Akim Demaille <akim@epita.fr>
16060 Don't let autom4te compute the `include' traces several times:
16061 first check that the trace cache file is up to date, and then
16062 compare its timestamp with that of the output.
16064 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16065 the preamble. Don't require 5.005 as Autom4te::General does it,
16066 and better yet (use `use', not `require'!).
16067 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16068 Class::Struct as Autom4te::Struct.
16069 * lib/Autom4te/General.pm (File::stat): Use it.
16070 (&mtime): New, export it.
16071 * bin/autom4te.in: Use it.
16072 Declare `$req' is invalid if it is outdated.
16073 Don't declare it valid before saving it if something went wrong.
16075 2001-08-04 Akim Demaille <akim@epita.fr>
16077 Autom4te shall not encode Autoconf data, and preselecting traces
16078 must be proposed to the users.
16080 * bin/autom4te.in (@required_trace): Remove.
16081 (@preselect): New.
16082 (&parse_args, &print_usage): -p, --preselect is a new option.
16083 (&up_to_date_p): Adjust.
16084 * bin/autoconf.in: Preselect some Autoconf macros.
16086 2001-08-04 Akim Demaille <akim@epita.fr>
16088 * tests/tools.at (autoconf --trace: user macros): Check traces on
16089 macros invoked without arguments, and macros invoked with multiple
16090 lines arguments.
16092 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
16094 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
