1949 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1951 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1952 check_SCRIPTS. Building the wrappers for `all' allows help2man
1953 to use them for the manpages.
1954 Report by Benoit Sigoure.
1956 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1958 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1960 Fix some write failure cases in Autotest.
1961 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
1962 upon write failures for --help, --version, --list.
1963 Guard against write failures for intermediate created scripts.
1964 <at_func_create_debugging_script>: Do not make the debugging
1965 script executable if it is not complete.
1967 2007-12-12 Eric Blake <ebb9@byu.net>
1969 Fix thinko in earlier patch - m4_join isn't defined yet.
1970 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1971 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1972 (m4_require): Use m4_do, not m4_join.
1974 Fix some whitespace tests on cygwin.
1975 * tests/tools.at (autom4te and whitespace in file names): Restore
1976 font-lock. Create $TMPDIR before it might be used.
1978 Fix spurious testsuite failure with M4 1.4.11.
1979 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1981 Optimize AC_REQUIRE.
1982 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1983 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1984 (m4_require): Avoid extra macro calls.
1986 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1988 * tests/torture.at (srcdir): Fix quoting.
1990 Do not pass top_srcdir to configure scripts in testsuite.
1991 * tests/autotest.at (srcdir propagation): Copy install-sh to
1992 source tree.
1993 (my only test): Drop setting of `top_srcdir'.
1994 * tests/base.at (Input/Output): Likewise.
1995 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1996 config.guess, and config.sub to test source tree.
1997 Drop AC_CONFIG_AUX_DIR setting.
1998 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1999 * tests/torture.at (Substitute a 2000-byte string): Drop
2000 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
2001 (Substitute a newline, datarootdir workaround): Likewise.
2002 (Define a newline): Adjust for linenumber changes in configure.ac.
2003 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
2005 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
2006 if `pwd` contains whitespace.
2008 Quote $abs_top_srcdir in tests.
2009 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
2010 * tests/tools.at (Syntax of the shell scripts): Likewise.
2012 * tests/m4sh.at (LINENO): Quote $0.
2014 Fix testsuite program wrapper for whitespace in `pwd`.
2015 The problem here is that the usual mantra is that command
2016 variables can contain arguments, thus we cannot just escape
2017 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
2018 $top_builddir/tests directory early in $PATH, so that the
2019 wrappers are found by their plain name.
2020 * tests/wrapper.as: Put $testdir early in $PATH.
2021 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
2023 Proper config.status --file/--header and $srcdir escaping.
2024 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
2025 characters in $ac_file_inputs.
2026 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
2027 accordingly.
2028 * tests/torture.at (datarootdir workaround): Adjust.
2029 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
2031 Fix Autotest for whitespace in `pwd`.
2032 * lib/autotest/general.m4 (AT_INIT)
2033 <at_func_create_debugging_script, Driver Loop>:
2034 Quote $at_group_dir.
2035 * tests/autotest.at (whitespace in absolute testdir): New test.
2037 * lib/autom4te.in: Quote @datadir@.
2039 Proper file name escaping in Autoconf programs and Perl modules.
2040 This includes escaping of characters special to the shell
2041 as well as special to Perl, e.g., leading `<' or `>'.
2042 For example, when $file starts with `>', `open ">$file"'
2043 wrongly tries to append to a different file.
2044 * bin/autoconf.as: Fix quoting for autom4te options.
2045 * lib/Autom4te/General.pm (shell_quote): New function, taken
2046 from coreutils, written by Jim Meyering.
2047 (mktmpdir): Use it.
2048 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
2049 and open_quote.
2050 * bin/autoreconf.in (parse_args): Likewise.
2051 * bin/autoscan.in (main): Likewise.
2052 * bin/autoupdate.in (main): Likewise.
2053 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
2054 * bin/ifnames.in: Likewise, XFile usage fixes.
2055 * tests/tools.at (autom4te and whitespace in file names): Extend
2056 test. Test twice, with special characters allowed on w32, and the
2057 rest. Test leading and trailing whitespace, for `open_quote'.
2058 (autotools and whitespace in file names): New, analogous test.
2059 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
2060 by Russ Allbery and Eric Blake.
2062 Sync from Automake.
2063 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
2064 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
2065 * lib/Autom4te/FileUtils.pm (open_quote): New function.
2066 (update_file, contents): Use it.
2068 * Makefile.am (autom4te-update): Rewrite for git.
2070 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2072 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
2074 Fix copyright years.
2075 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
2076 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
2078 2007-12-04 Eric Blake <ebb9@byu.net>
2080 Manually resync with gnulib, since 'make cvs-update' no longer works.
2081 * build-aux/config.guess: New upstream version.
2082 * build-aux/config.sub: Likewise.
2084 When using older automake, don't downgrade build-aux/texinfo.tex.
2085 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
2086 * doc/Makefile.am (TEXINFO_TEX): Add.
2088 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
2090 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
2091 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
2092 #undef as this runs afoul of our new way of creating config.h.
2093 Problem reported by Jim Meyering in
2094 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
2096 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2098 Fix autom4te for unusual characters in input file names.
2099 * bin/autom4te.in (files_to_options): Quote active characters
2100 for the shell.
2101 * tests/tools.at (autom4te and white space in file names):
2102 New test.
2104 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
2105 Document that Tru64 awk always splits $0.
2107 2007-11-24 Stepan Kasal <kasal@ucw.cz>
2109 * lib/autotest/general.m4 (AT_INIT): Do not extract the
2110 `#AT_STOP_...' line at the end of each test.
2112 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2114 * lib/autotest/general.m4 (AT_INIT): For awk line number
2115 extraction script, ensure `$at_group' has a defined value
2116 even for the empty set, and properly quote its usage inside
2117 the awk script.
2119 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2121 * doc/autoconf.texi (Shell Functions): New chapter. Document
2122 IRIX sh $0 issue in functions, move content from ...
2123 (Portable Shell): ... here.
2124 (Shell Script Compiler): Note that shell functions are not
2125 totally unportable any more.
2127 2007-11-22 Stepan Kasal <kasal@ucw.cz>
2128 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2130 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
2131 extracting the line numbers of the last needed test.
2133 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2135 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2136 Fix quoting.
2138 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2140 Fix IRIX testsuite debugging failures: $0 in functions.
2141 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
2142 Do not use $0 inside a function, as IRIX sh will set that to the
2143 function name rather than the script invocation name.
2145 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
2146 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2148 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
2149 to extract test scripts.
2150 (AT_INIT): Extract and cache test script line numbers.
2152 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2154 * lib/autotest/general.m4: Revert 2007-11-15 patch and
2155 subsequent fixups; the awk -> here-document conversion trashes
2156 performance too much with AIX sh.
2158 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2160 * tests/local.at: Do not test m4, perl with AT_TESTED.
2162 Diagnose and guard against write errors dealing with config.status.
2163 The general idea is this: all write failures from `configure'
2164 writing `config.status' are indicated by $ac_write_error, which
2165 is only checked at the end. This is safe because config.status
2166 code is not executed before the file is complete. Other write
2167 failures, be they inside config.status, or in sub shell/awk
2168 scripts spawned from configure or config.status, typically need
2169 earlier checking, as their results are used right afterwards.
2170 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
2171 before writing config.status, check afterwards.
2172 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
2173 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
2174 Set `ac_write_error' for write failures to config.status. Barf
2175 upon write failures to temporary files.
2176 Adjust note about closing and reopening the here-document.
2177 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
2178 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
2179 reopening the here-document.
2180 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2181 Ensure `ac_write_error' does not escape into config.status.
2182 Also, add a couple of code paths not yet exercised in the test
2183 suite: a config file with input from stdin, and a config header
2184 output to stdout.
2185 Suggestion for catching write errors by Bruno Haible.
2187 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2189 Avoid error with Tru64 awk and testsuite lines with many words.
2190 * lib/autotest/general.m4 (AT_INIT): In the awk script that
2191 reads the testsuite, set the field separator to an unusual value,
2192 in order to not run over the limit of 199 fields. Tru64 4.0D awk
2193 even splits the input if $i, i>0, was never accessed in the script.
2195 Revert 2007-10-17 change.
2196 * TODO: Multiline args in config files and headers mean something
2197 different and are not fixed, see
2198 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
2199 Report by Stepan Kasal.
2201 * doc/autoconf.texi (Generic Programs): Fix typo.
2203 2007-11-16 Stepan Kasal <kasal@ucw.cz>
2205 AC_*_TOOL does not canonicalize the prefix
2206 * doc/autoconf.texi (Generic Programs): Do not say that
2207 the *_TOOL macros canonicalize, they simply use the `host_alias'.
2209 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2211 Diagnose write errors in config.status instantiations.
2212 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
2213 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
2214 on write errors.
2215 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2216 Extend test to also check for some write error failures, using...
2217 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
2218 Report by Bruno Haible.
2220 Indentation fixups.
2221 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
2222 indentation.
2223 (_AT_CHECK): Use less indentation, to save space.
2225 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2227 Add witness macro for @top_build_prefix@ substitution.
2228 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
2229 (_AC_OUTPUT_FILE): Mention it here.
2231 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
2232 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2234 * lib/autotest/general.m4 (at_func_test): Remove.
2235 (AT_INIT): Pre-extract test groups into separate files.
2236 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
2237 Remove at-test-source files together with the $at_group_dir.
2238 * tests/autotest.at (Long test source lines): New test.
2240 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2242 Shell functions and variables may share a namespace.
2243 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
2244 limitation.
2246 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
2248 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
2249 gnulib.
2251 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2253 * lib/autoconf/status.m4: Fix a couple of comment typos.
2255 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
2257 2007-11-13 Jim Meyering <meyering@redhat.com>
2259 Clean up the rule to create "expr".
2260 * tests/Makefile.am (expr): Don't redirect directly to target.
2261 Redirect just once, not for each echo statement.
2262 Use $@, not literal "expr".
2264 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
2266 Don't worry about preprocessor when testing long long.
2267 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
2268 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
2269 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
2270 These no longer check for preprocessor flaws.
2271 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
2272 Do not check for preprocessor flaws.
2274 2007-11-13 Jim Meyering <meyering@redhat.com>
2276 Adapt dependencies, now that a version change doesn't modify configure.ac
2277 * GNUmakefile: Remove "make clean" kludge.
2278 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
2279 configure.ac.
2280 Don't redirect directly to target.
2281 Use $@, not literal "version.m4".
2283 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2285 * doc/autoconf.texi (Making testsuite Scripts): Document
2286 ":;{" shorthand as in previous patch.
2288 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
2290 * doc/autoconf.texi (Limitations of Builtins): Document problem
2291 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
2292 for the workaround.
2293 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
2294 Use ":;{" shorthand.
2295 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
2297 2007-11-12 Jim Meyering <meyering@redhat.com>
2299 Add more non-srcdir build support.
2300 * GNUmakefile (dummy): Split a long line.
2301 Add -v option to autoreconf invocation.
2303 Remove the autoreconf-provided INSTALL, so that we regenerate it.
2304 * GNUmakefile (dummy): Remove INSTALL.
2306 Remove racy commands to build scripts in bin/ and tests/.
2307 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
2308 are guaranteed to be built, remove the rules that tried to build
2309 them. Before, with a parallel build, these rules could lead to
2310 two processes writing tests/wrapper.in concurrently.
2312 Build in man/ only *after* building in bin/ and tests/.
2313 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
2314 in both bin/ and tests/.
2316 Accommodate non-srcdir build-from-checkout.
2317 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
2318 Use git's --git-dir=$srcdir/.git option.
2319 Add quotes, in case tarball_version_file contains shell meta-characters.
2320 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
2321 * configure.ac: Pass "." to git-version-gen.
2323 Avoid spurious test failures due to version skew.
2324 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
2326 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2328 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
2329 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
2330 Remove conftest.dSYM directory.
2331 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
2332 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
2333 Remove `conftest.*' recursively.
2334 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
2335 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2336 Likewise.
2337 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
2338 * THANKS: Update.
2339 Report and analysis by Jeff Squyres and Peter O'Gorman.
2341 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
2343 Fix typos in variable names.
2344 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
2346 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
2348 Document that $((expression)) is not portable.
2349 * doc/autoconf.texi (Shell Substitutions): Here.
2351 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2353 Ignore configure --help* errors due to LINENO-impaired shells.
2354 * tests/torture.at (Configuring subdirectories, Deep Package):
2355 In the --help* tests in read-only trees, make `.' temporarily
2356 writable again for the `stderr' file, and ignore errors due to
2357 the attempt to write configure.lineno.
2358 Report by Patrick Welche.
2360 2007-11-10 Jim Meyering <meyering@redhat.com>
2362 Generate package.m4 in build-dir, not srcdir.
2363 * tests/Makefile.am (package.m4): Adjust target.
2364 Don't redirect directly to $@.
2365 (CLEANFILES): Add package.m4.
2366 ($(TESTSUITE)): Depend on just-built package.m4, not the one
2367 in $(srcdir).
2368 When running $(AUTOTEST), search "." before searching $(srcdir).
2370 Avoid a race condition that would make parallel "distclean" fail.
2371 * tests/Makefile.am (distclean-generic): Replace the default,
2372 automake-provided rule with an identical one, but with an additional
2373 dependency on distclean-local. Simply adding the dependency would
2374 cause automake not to emit the rule at all.
2375 * BUGS: Building with -jN works, now.
2377 Distribute git-version-gen.
2378 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
2379 since GNUmakefile is distributed, and requires it for dist* rules.
2381 Remove two more generated files from version control.
2382 * INSTALL: Remove generated file.
2383 * lib/autoscan/autoscan.list: Remove generated file.
2385 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
2387 * GNUmakefile (PATH): Remove stray apostrophes; they become
2388 part of PATH, which isn't wanted here.
2390 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2392 New config files output variable `top_build_prefix'.
2393 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
2394 `top_build_prefix'.
2395 * doc/autoconf.texi (Preset Output Variables): Document it.
2396 * NEWS: Update.
2397 Report by Bob Friesenhahn.
2399 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
2400 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
2401 function, to parametrize arithmetic with expr vs. the shell.
2402 Use it where possible.
2403 Suggestion by Benoit Sigoure.
2405 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
2407 Adjust the documentation of autotest WRT atlocal.
2408 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
2409 when using Automake, to write a rule to produce atlocal, since it's
2410 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
2411 distributed, not atconfig.in.
2413 2007-11-04 Eric Blake <ebb9@byu.net>
2415 Update list information.
2416 * README: Mention new autoconf-commit list.

2512 Make inter-release --version output more useful.
2514 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
2515 which indicates that it is built using the 19th change set
2516 (in _some_ repository) following the "v2.61a" tag, and that 58dd
2517 is a prefix of the commit SHA1.
2518 * build-aux/git-version-gen: New file.

2528 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
2529 git-version-gen doesn't match $(VERSION), but only for dist targets.

2569 preprocessor.
2571 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
2573 Don't check for bug in HP-UX 11.00 cpp.
2574 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
2575 Use -1ull rather than -1u, since that causes problems with gnulib; see
2576 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

2598 unnecessarily. Do not try running `/bin/sh configure' with a
2599 configure script to be found in $PATH, if the shell does not do
2600 this resolution. Fixes test failure on FreeBSD.
2602 Fix config header generation with AIX awk.
2603 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
2604 script, use helper array D_is_set, as `" 0"' does not evaluate

3827 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
3828 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
3829 works but the latter doesn't, then it's a valid type.
3830 This lets people use function types and so forth.
3831 For C++ there doesn't seem to be a simple solution, so leave it alone.
3832 (AC_CHECK_SIZEOF): Allow argument to be a variable.
3833 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
3834 AC_CHECK_TYPE; that wasn't documented or necessary.
3836 2007-04-11 Stepan Kasal <kasal@ucw.cz>
3838 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

3892 (Limitations of Usual Tools): Also list \< and \>, and mention that
3893 HP-UX's grep, like the one from Solaris, does not support that syntax.
3895 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3897 * doc/autoconf.texi (Specifying Names): `--host' does not
3898 change the build type.
3900 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3902 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3903 suggests AC_CONFIG_HEADERS.

3922 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3923 Reindent for sanity's sake.
3925 2007-02-24 Eric Blake <ebb9@byu.net>
3927 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3928 copyright.

3936 status of rm so we know when it failed.
3937 If cleaning of test dir failed before running the test, warn.
3938 Output the line separator in verbose mode before the warning

3956 carriage return.
3957 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3958 with traditional Awk and begin.
3959 * tests/torture.at (Limitations of Builtins): Document the problem

4002 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4004 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
4005 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
4006 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
4007 substitution will still be done by the special code.
4008 Report by Jim Meyering.
4010 * doc/autoconf.texi (File System Conventions): Mention that
4011 $PATH_SEPARATOR is for the build system only.

4023 Report against Automake by Patrick Welche.
4025 2007-01-15 Stepan Kasal <kasal@ucw.cz>
4027 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
4029 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4031 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
4032 early on the reader side, drop stderr of the input to avoid
4033 `broken pipe' error output; this may happen even with shell
4034 builtin `echo' of some bash versions. Reports by Ian Macdonald
4035 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
4037 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4039 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
4040 separate items of `ac_user_opts', to avoid long lines.
4041 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
4043 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4045 * doc/autoconf.texi: Fix some typos.
4047 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
4049 Fix some wording problems noted by Paolo Bonzini in:
4050 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
4051 * doc/autoconf.texi (Signed Overflow Examples): Give more
4052 discussion about the allow_superuser_privileges example,
4053 and change it a bit to make things clearer.
4054 (Optimization and Wraparound): Clarify whether the compiler
4055 will generate an infinite loop for the example derived from
4056 Autoconf's mktime test.
4057 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
4058 Also, clarify unsigned multiplication overflow.
4060 2007-01-04 Eric Blake <ebb9@byu.net>
4062 * bin/Makefile.am (RELEASE_YEAR): New macro.
4063 (edit): Use it to supply correct copyright year to scripts.
4064 * bin/autoconf.as (version): Use it.
4065 * bin/autoheader.in ($version): Likewise.
4066 * bin/autom4te.in ($version): Likewise.
4067 * bin/autoreconf.in ($version): Likewise.
4068 * bin/autoscan.in ($version): Likewise.
4069 * bin/autoupdate.in ($version): Likewise.
4070 * bin/ifnames.in ($version): Likewise.
4072 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
4074 * doc/autoconf.texi (Integer Overflow): Revised based on today's
4075 feedback. The most important changes document what happens when
4076 you convert an out-of-range value to a signed integer type, and
4077 say that (sum < a) != (b < 0) reliably detects overflow when sum =
4078 a + b.
4080 * doc/autoconf.texi (Integer Overflow): Greatly expand and
4081 rewrite, taking notions from the recent discussion on the gcc and
4082 autoconf mailing lists; please see
4083 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
4084 and follow the many links.
4085 (Integer Overflow Basics, Signed Overflow Examples):
4086 (Optimization and Wraparound, Signed Overflow Advice):
4087 (Signed Integer Division): New sections.
4089 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
4091 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
4092 preprocessor macro arguments in traced name.
4093 * doc/autoconf.texi (Defining symbols): Document longstanding
4094 support for AC_DEFINE-ing macros with arguments, and document
4095 behavior when the same variable has multiple AC_DEFINEs.
4096 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
4097 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
4098 macros directly, giving much shorter and simpler code.
4100 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
4102 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
4103 space before "$ac_configure_args" to prevent a 'config.status
4104 --recheck' failure if ac_configure_args doesn't contain a leading
4105 space. This works around a problem with the XEmacs configure.ac,
4106 which uses the (undocumented) ac_configure_args variable
4107 inconsistently with Autoconf.
4109 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
4111 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
4112 Include <limits.h>, and use its INT_MAX to rewrite the
4113 j loop so that it does not overflow 'int'. Problem reported by
4114 Ralf Wildenhues in
4115 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
4116 Play it safe by shifting left by 1 rather than multiplying by 2,
4117 as GCC is less likely to optimize this away when the value
4118 is signed (when it assumes overflow leads to undefined behavior).
4119 Also, don't assume time_t uses two's complement.
4121 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4123 * tests/torture.at (Substitute a 2000-byte string): Avoid using
4124 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
4125 dumps core on it. Report by Tim Rice.
4127 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4129 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4130 --disable-option-checking to --help output even when
4131 AC_PRESERVE_HELP_ORDER is not used.
4132 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
4133 --with argument, rather than argument with [-.] replaced by
4134 underscores.
4135 * NEWS: Fix typo in previous change; the news was in the
4136 wrong section.
4138 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
4140 * NEWS: Warnings are now generated by default for unknown
4141 --enable-* and --with-* options.
4142 * doc/autoconf.texi (Option Checking): Renamed from
4143 (Configure Option Checking). Tighten up the wording a bit.
4144 (External Software, Package Options): Cross-reference to Option
4145 Checking, and use this to shorten our section.
4146 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
4147 "$x" to test "x$foo" != x.
4148 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
4149 Don't warn if $enable_option_checking is "no".
4150 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
4151 ac_unrecognized_opts to the empty string.
4152 Don't echo the unrecognized opts, as this might mishandle
4153 backslashes or leading -.
4154 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
4155 usage next to the other --disable-FEATURE options in the
4156 help string.
4158 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
4160 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
4161 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
4162 Print warning for unrecognized --with and --enable options
4163 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
4164 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
4165 Disable option checking when subdirs are configured.
4166 (AC_OUTPUT): If warnings are enabled, print warning about
4167 unrecognized --with and --enable options at the end of
4168 the configure output (as well as at the beginning).
4169 * doc/autoconf.texi (Option Checking): New node.
4170 Document new option warning functionality.
4172 2006-12-16 Eric Blake <ebb9@byu.net>
4174 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
4175 * NEWS: Start news for current version.
4177 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
4179 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4180 Define HAVE_GETMNTENT to 1, not to the empty string.
4181 Problem originally reported by Jochen Friedrich in
4182 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
4184 This change prompted by a problem report by Andrey Simonenko in
4185 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
4186 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
4187 object-like macros only, in the traditional portable character
4188 set.
4189 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
4190 Warn about attempts to define things that are not identifiers.
4191 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
4192 awful hack that AC_DEFINEd macro names containing parentheses.
4194 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
4196 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
4197 too drastic, even if Texinfo in theory requires it for info mode.
4199 (config.status Invocation): Renamed back from Recreating a
4200 Configuration).
4201 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
4202 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
4204 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4206 * NEWS: Version 2.61a.
4208 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
4209 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4211 * NEWS: Document changes with echo and printf, and the lack
4212 of limits on the total size of multi-line values of substituted
4213 variables, and the AC_FUNC_FSEEKO fix.
4215 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
4217 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
4218 Writing configure.ac.
4219 (Autoconf Input Layout): Renamed from configure.ac Layout.
4220 (Recreating a Configuration): Renamed from config.status Invocation.
4221 (Obsolete Recreation): Renamed from Obsolete config.status Use.
4222 (acconfig Header): Renamed from acconfig.h.
4223 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
4224 (Writing Testsuites): Renamed from Writing testsuite.at.
4225 (Autom4te Cache): Renamed from autom4te.cache.
4227 * BUGS: Remove mention of VPATH problem, since it's now documented
4228 not to be a bug in the Autoconf build procedure itself, but rather
4229 a problem with the proprietary `make' programs.
4231 * doc/autoconf.texi (Build Directories): Add a cross reference
4232 to VPATH and Make.
4234 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
4235 * doc/standards.texi: Sync from gnulib.
4237 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
4238 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
4239 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
4240 generated automatically.
4242 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
4244 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
4245 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
4246 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
4248 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4250 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
4251 `CEOF$ac_eof' special marker, the awk script cannot contain a
4252 line matching `^CEOF', so this is not needed any more.
4253 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
4254 special marker in the test.
4256 2006-12-06 Stepan Kasal <kasal@ucw.cz>
4258 * tests/tools.at (autom4te preselections): Use `find -newer';
4259 remove one of the sleeps.
4261 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
4262 more readable, using ...
4263 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
4265 * doc/autoconf.texi (autoheader Invocation): Do not double-
4266 quote the parameter of `AH_BOTTOM' in the example.
4268 2006-12-05 Stepan Kasal <kasal@ucw.cz>
4270 * doc/autoconf.texi (Configuration Headers): Remove the
4271 example with multiple input files.
4272 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
4273 multiple input files.
4275 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4277 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
4278 creating the awk substitution script, handle one input line at a
4279 time, so that the maximum length of a substituted (multi-line)
4280 value is not limited by the size of the sed pattern space.
4281 The trade-off is a slightly repetitive sed script.
4282 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
4283 can only have up to 7 characters, due to Solaris 10 /bin/sed.
4284 * tests/torture.at (Substitute a 2000-byte string): Increase the
4285 test with several long lines, they should not be caught by sed
4286 limits any more.
4288 * tests/tools.at (autom4te preselections): New test, to flag
4289 entries missing from autom4te.cfg.
4290 Report by David Byron <dbyron@hheld.com>.
4292 * tests/torture.at (Substitute a 2000-byte string): Actually use
4293 AC_PROG_AWK, so the last change works as intended.
4294 (Substitute and define special characters): Likewise.
4295 (Substitute a newline): Likewise.
4297 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
4298 instead of `awk' consistently.
4299 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
4300 * tests/torture.at (Torturing config.status): Test both the
4301 result of AC_PROG_AWK and plain awk.
4302 (Substitute a 2000-byte string): Likewise.
4303 (Substitute and define special characters): Likewise.
4304 (Substitute a newline): Likewise.
4306 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
4308 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
4309 can be assigned to a function pointer. Problem reported by
4310 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
4311 part of a patch by Ralf Wildenhues in that same bug report.
4313 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
4315 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4316 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
4318 2006-12-01 Eric Blake <ebb9@byu.net>
4320 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
4321 cross-compiling from cygwin to mingw.
4322 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
4323 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
4324 to lib/autoconf/c.m4.
4326 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4328 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4329 string for more reliable failure. Wrap the entire test that
4330 causes the broken Solaris printf to dump core, in a subshell,
4331 so the segmentation fault message is reliably suppressed.
4332 Fix shell expansion errors by using /usr/ucb/echo always;
4333 avoid an error on systems without it by another subshell.
4334 Avoid m4 expansion of `$1'. Set the zeroth argument of the
4335 subshell-$as_echo to `as_echo', for better error message.
4337 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4339 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
4340 `BASH_SOURCE' contain a newline, set them to empty, as they may
4341 not be unset.
4343 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
4345 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
4346 years and is too hard to maintain now. The last straw was
4347 reported by Jerker Baeck in
4348 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
4349 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
4350 * doc/autoconf.texi (Particular Functions): Move
4351 AC_FUNC_SETVBUF_REVERSED from here...
4352 (Obsolete Macros): ... to here. Say that it does nothing now.
4353 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
4354 Turn into (almost) a no-op.
4356 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4357 (AC_C_VOLATILE):
4358 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
4359 These macros are obsolescent and new applications shouldn't need them.
4360 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
4361 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
4362 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
4363 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4364 (AC_FUNC_VPRINTF): Likewise.
4365 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
4366 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
4367 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
4369 * doc/autoconf.texi (Setting Output Variables): Mention that
4370 @VAR1@VAR2 has unspecified behavior. Problem reported by
4371 Ralf Wildenhues.
4372 * NEWS: Mention this.
4374 * Makefile.am: Put only a single '#' into the copyright notice,
4375 so that it's also present in the output file. Standardize wording
4376 in makefile copyright notices to match GNU coding standards.
4377 * bin/Makefile.am: Likewise.
4378 * doc/Makefile.am: Likewise.
4379 * lib/Makefile.am: Likewise.
4380 * lib/freeze.mk: Likewise.
4381 * lib/autoconf/Makefile.am: Likewise.
4382 * lib/autoscan/Makefile.am: Likewise.
4383 * lib/autotest/Makefile.am: Likewise.
4384 * lib/m4sugar/Makefile.am: Likewise.
4385 * man/Makefile.am: Likewise.
4386 * tests/Makefile.am: Likewise.
4387 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
4388 one-line file.
4390 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4392 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
4393 in the sed script that mangles the awk script: delete up to the
4394 first exclamation mark only.
4395 * tests/torture.at (Substitute and define special characters):
4396 Test '!' too.
4398 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4400 Rewrite config files generation: avoid quadratic growth in
4401 the number of substituted variables by using awk instead of sed
4402 for the bulk of the substitutions.
4403 * NEWS: Mention this.
4404 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
4405 forbidden in the output (and thus input) file.
4406 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
4407 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
4408 generate just one large awk script for substitutions,
4409 eliminating much of the earlier complexity, while adding some
4410 new complexity. Only expand the substitution templates at
4411 configure time, for smaller configure script size. If
4412 _AC_SUBST_FILES are used, test 'awk' for working getline support
4413 at config.status time. If absent, interpolate through the
4414 shell. The awk script was written with much help
4415 from Paolo Bonzini and Paul Eggert.
4416 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
4417 (_AC_SED_FRAG_NUM): Likewise.
4418 (_AC_SUBST_CMDS): Renamed from...
4419 (_AC_SED_CMDS): ...this.
4420 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
4421 * tests/torture.at (Substitute a 2000-byte string): Also
4422 substitute a line with 1000 words, and a variable with several
4423 long lines.
4424 (Substitute and define special characters): Test awk special
4425 characters, and put substitution input strings `@foo@' in the
4426 output, to test that no recursion happens; test several other
4427 combinations from Paolo Bonzini.
4429 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
4431 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
4432 that replaced echo with AS_ECHO where this wasn't necessary.
4433 Problem reportd by Ralf Wildenhues.
4434 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
4435 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
4436 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
4438 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4440 * lib/freeze.mk (GREP): Removed, no need to initialize this.
4442 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
4444 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4445 that traditional Awk lacks 3-arg "split". It has it.
4446 Mention that FS must be a single character, and a few other
4447 99-byte limits of traditional Awk.
4448 Mention that if (i in a) doesn't work with traditional Awk.
4450 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
4452 * tests/autotest.at (BSx641-newline in command):
4453 (BS-BS-newline in command, BSx640-newline in command):
4454 (Newline-CODE-BS-newline in command):
4455 (Single-quote-BS-newline in command):
4456 (Single-quote-newline-BS-newline in command):
4457 Use printf '%s\n' instead of echo, for portability to hosts
4458 where echo interprets backslashes. This will break on hosts
4459 that lack printf, but for now let's assume all such hosts
4460 are dead (if not, we should get reports of test failures).
4462 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4464 'echo' has some portability problems, when given a first argument
4465 with a leading '-', or when given any argument containing '\'.
4466 Avoid using 'echo' in these cases.
4467 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
4468 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
4469 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4470 * lib/autotest/general.m4 (AT_INIT): Likewise.
4471 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
4472 argument might be unportable.

4491 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
4492 * bin/autoconf.as: Redo verbose flag implementation, as the old
4493 scheme wouldn't work with AS_ECHO.
4494 * lib/autotest/general.m4 (AT_INIT): Likewise.
4495 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
4496 Don't use ECHO_T, since ECHO_N is now reliable.
4497 * lib/autotest/general.m4 (AT_INIT): Likewise.
4498 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
4499 rather than using a here-document to put the script into a file.
4500 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
4501 use AS_ECHO.
4502 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
4503 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
4504 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
4505 bug, but we might as well stop using ECHO_N and ECHO_C internally.
4506 * lib/autotest/general.m4 (AT_SETUP): Likewise.
4507 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
4508 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4509 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
4510 operand, as AS_ECHO requires. Avoid double file name expansion.
4511 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
4512 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
4513 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
4514 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
4515 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
4516 Double-quote strings that would otherwise contain M4 comments.
4517 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
4519 * configure.ac (AC_INIT): Bump to 2.61a.
4520 * NEWS: Likewise.
4522 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
4524 Version 2.61.
4526 * configure.ac (AC_INIT): Bump to 2.61.
4527 * NEWS: Likewise.
4529 * tests/autotest.at (Macro with backslash in a test title):
4530 Comment out for now, as this tests neither fails nor passes
4531 reliably. Problem reported by Ralf Wildenhues.
4533 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4535 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
4536 in previous change, which caused test failures.
4538 2006-11-16 Stepan Kasal <kasal@ucw.cz>
4540 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
4541 code for --enable, --disable, --with, and --without to...
4542 (_AC_INIT_PARSE_ENABLE): ... a new macro.
4543 * doc/autoconf.texi (Package Options):
4544 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
4546 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
4548 Import these changes from config via gnulib:
4550 2006-11-15 Ben Elliston <bje@gnu.org>
4552 From Josselin Mouette <joss@debian.org>:

4583 Import these changes from texinfo via gnulib:
4585 2006-11-08 Karl Berry <karl@gnu.org>

4589 no further ado.
4591 2006-11-05 Karl Berry <karl@gnu.org>
4593 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

4605 first argument may also contain dots.
4607 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
4609 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
4610 benefit of platforms like Solaris+GCC where it is common to have a
4611 non-working g++ installation.
4613 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4614 and Joel E. Denny <jdenny@ces.clemson.edu>
4615 and Paul Eggert <eggert@cs.ucla.edu>
4617 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
4618 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
4619 ./micro-suite.
4621 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4623 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
4624 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
4625 Imported from a similar patch to gnulib by Bruno Haible.
4627 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4629 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

4637 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
4638 Matthew Woehlke.
4640 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4642 * tests/torture.at (Configuring subdirectories): Do not skip
4643 Automake 1.10 nor future Automake 11.1 (sic).
4645 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
4646 and Stepan Kasal <kasal@ucw.cz>
4648 Handle special characters in test case titles correctly.
4649 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
4650 properly.
4651 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
4652 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
4653 argument. Extend to check titles printed by ./micro-suite and
4654 ./micro-suite -l and the title in micro-suite.log.
4655 (Backquote in a test title,
4656 Single-quote in a test title,
4657 Double-quote in a test title): Don't expect failure anymore.
4658 (Backslash in a test title): Put a non-whitespace character after the
4659 backslash so that Bourne shells might actually see it as an escape
4660 sequence.
4661 (Brackets in a test title,
4662 Pound in a test title,
4663 Comma in a test title,
4664 Quoted Macro in a test title,
4665 Macro in a test title,
4666 Macro with single-quote in a test title): New tests.
4667 (Macro with backquote in a test title,
4668 Macro with double-quote in a test title,
4669 Macro with backslash in a test title): New tests expected to fail.
4670 * tests/torture.at (#define header templates): M4-quote this title in
4671 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
4672 The visible effect was a stray [] in the testsuite output.
4674 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4676 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
4677 `trap ... 0' inside a function, for AIX sh.
4679 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
4681 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
4682 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
4683 5363) simply issues a warning when dividing by zero at compile
4684 time. Problem reported by Elias Pipping.
4686 2006-10-26 Eric Blake <ebb9@byu.net>
4688 * THANKS: Update.
4689 * doc/autoconf.texi (Evaluation Macros): Improve the example to
4690 show effect on macros that expand with commas.
4691 Reported by Joel E. Denny.
4693 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
4694 Also work with M4 1.4.8.
4696 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
4698 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
4699 Jim Meyering.
4701 2006-10-25 Stepan Kasal <kasal@ucw.cz>
4703 * tests/tools.at (autom4te --force): New test, verifies that
4704 `--force' always rewrites the output file.
4706 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4708 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
4709 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
4711 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4713 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
4715 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
4717 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4718 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
4719 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
4720 reported by Nelson H. F. Beebe for Coreutils 6.4.
4722 * tests/tools.at (autoconf --trace: user macros): Remove test
4723 for tracing multiline macros, since m4 1.4.7a uses a different
4724 way to number lines. Problem reported by Ralf Wildenhues.
4726 2006-10-24 Stepan Kasal <kasal@ucw.cz>
4728 * bin/autom4te.in (handle_m4): Do not redirect stdin to
4729 /dev/null since the heuristics for interactive behaviour was
4730 fixed in CVS m4.
4732 * bin/autom4te.in: With --force, always refresh the output
4733 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
4735 * bin/autoconf.as: Fix the verbose message at the end.
4737 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

4752 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
4753 AC_CACHE_CHECK_INT, since it's no longer public.
4754 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
4755 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
4757 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4759 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
4761 2006-10-19 Eric Blake <ebb9@byu.net>

4783 2006-10-14 Stepan Kasal <kasal@ucw.cz>
4785 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
4786 looking for special shell characters.
4787 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
4788 macro defined by AS_VAR_PUSHDEF before passing it as a
4789 parameter.

4800 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4802 (Imported from Automake.)
4803 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
4804 which incorrectly sets the mode of an existing destination
4805 directory. In some cases the unpatched install-sh could do the
4806 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
4807 system. We hope this is rare in practice, but it's clearly worth
4808 fixing. Problem reported by Alex Unleashed in
4809 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
4810 Also, don't bother to check for -m bugs unless we're using -m;
4811 suggested by Stepan Kasal.
4813 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
4815 Import this change from Automake:
4817 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

4819 is enabled by default with gnu and gnits strictness.
4820 Report from Bruno Haible.
4822 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

4824 gnu and gnits modes.
4826 Import this change from Config:
4828 2006-09-20 Ben Elliston <bje@gnu.org>

4831 Import this change from Gnulib:
4833 2006-09-16 Karl Berry <karl@gnu.org>
4834 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,

4857 2006-10-13 Stepan Kasal <kasal@ucw.cz>
4859 * doc/autoconf.texi (Autoheader Macros): Warn that the text
4860 added to the template can get mangled.
4862 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4864 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
4865 include the default headers, and redefine obstack_chunk_alloc
4866 and obstack_chunk_free. Fixes false failure with glibc.
4868 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4870 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

4872 by Ralf Wildenhues.
4874 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4877 AC_PROG_CC.

4880 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4882 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
4883 the NonStop platform.
4884 * doc/autoconf.texi (Posix Variants): Likewise.
4885 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4887 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4888 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4889 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4890 Use a better substitute, by inspecting the output of "ls"
4891 rather than just using ":".
4892 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4893 rather than AS_EXECUTABLE_P, since we needn't worry about
4894 non-regular files here.
4896 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4897 due to configuration hassles with this. See Tonya Underwood's report
4898 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
4899 * doc/autoconf.texi (Special Shell Variables): Likewise.
4901 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

4905 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
4907 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4909 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4910 initialization which is not inherited through the environment
4911 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4912 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4914 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4916 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4917 problems with mkdir -p -m.
4919 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4921 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4922 comment about ac_cpp_err; it was incorrect, and anyway
4923 ac_cpp_err is being removed below.
4924 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4925 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4926 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4927 nobody uses it.
4928 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4929 with werror_flag and conftest.err and so forth. This is more
4930 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4931 and anyway the user shouldn't normally want to see this gorp logged.
4932 Problem reported by Ralf Wildenhues.
4933 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4934 empty, not 'no', since the rest of the code uses 'test -z'.
4936 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4938 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4939 Use a single call to AC_DO_TOKENS rather than multiple, for
4940 efficiency.
4941 (_AC_LINK_IFELSE): Test that resulting file is executable.
4942 Problem reported by mwoehlke in
4943 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4945 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4946 than creating a file to use with test -x; this is much faster.
4948 2006-10-02 Bruno Haible <bruno@clisp.org>
4950 * lib/autom4te.in (Automake-preselections): Add
4951 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4953 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4955 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4956 standard error, `experr' should be used, not `expout'.
4958 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4960 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4961 fseeko testing program twice; just use the earlier result.
4962 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4963 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4964 still doesn't let the program compile.
4965 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4966 failed.
4968 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4969 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4970 include it, without including anything else.
4971 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4972 expressions.
4973 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4975 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4977 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4978 `error.h', and include it, for a `error_at_line' prototype.
4979 Use a nonempty format string in the link test.
4980 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4981 for a declaration of wait3.
4983 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4985 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4986 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4987 can apply to constants too, and that it checks for macro defns.
4988 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4989 and simply cast the identifier to void. This handles structure
4990 values. Problem reported by Ralf Wildenhues.
4991 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4993 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4995 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
4996 structure, and function symbols.
4998 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5000 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
5001 member.

5013 warnings (uninitialized value).
5014 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
5015 present.
5016 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

5047 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
5048 --error-output, to avoid warnings with M4 2.0.
5050 2006-09-19 Stepan Kasal <kasal@ucw.cz>
5052 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

5063 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
5064 mistaken comment: the path has to be relative; do not use
5065 the path at runtime.
5067 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5069 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

5073 for both changes.
5074 * doc/autoconf.texi (Setting Output Variables): Fix example to
5075 not show `--silent' being passed to a `configure' re-run.

5079 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
5080 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
5081 for the existence of the directory at configure-time. That's
5082 too late, anyway. Problem reported by Stefan Seefeld.
5084 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
5085 7.1.4 /usr/bin/posix/sh described by Tim Rice in
5086 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
5088 2006-09-11 Stepan Kasal <kasal@ucw.cz>
5090 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
5091 works with GNU M4 1.4.3 again; make the normalized form
5092 match the current m4 message; fix the description.

5095 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
5097 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
5098 to catch glibc bug 2821
5099 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
5101 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
5102 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
5103 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
5104 assume C89.
5106 2006-09-08 Stepan Kasal <kasal@ucw.cz>
5108 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

5126 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
5127 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
5128 accept files with extension `.f'. For consistency, also prefer
5129 xlf over f77.
5130 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
5131 from last patch.

5151 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
5152 except the first two arguments are reversed.
5153 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
5154 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
5155 caches nor outputs a diagnostic. Suggested by Bruno Haible.
5156 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
5157 equivalent to the old AC_COMPUTE_INT.
5158 (AC_COMPUTE_INT): No longer caches or reports. New signature.
5159 All uses changed to AC_CACHE_CHECK_INT.
5160 * tests/base.at (AC_CACHE_CHECK_INT): New test.
5161 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
5163 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
5165 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
5166 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
5167 programs should use their Gnulib counterparts.

5170 obsolete macros with uses of non-obsolete macros.

5198 Fix Lex library problem reported to us by Julio Garvia.
5199 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
5200 for the default, which the user can override.
5201 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
5202 deal with LEXLIB.
5203 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
5204 didn't work if some values were cached but not others. Test for
5205 broken lex libraries like native ia64-hp-hpux11.22; see
5206 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
5207 work around the problem by preferring an empty LEXLIB to -lfl or
5208 -ll. Let the user set LEXLIB='' to indicate no library needed.
5210 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
5211 * README: Likewise.
5212 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

5271 (copyright-check): Use $() not ``.
5272 (maintainer-distcheck): Do not depend on changelog-check.
5273 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
5274 Also check for -Wpointer-arith.
5275 (WGET, WGETFLAGS, tgz-md5, tgz-sha1, bz2-md5, bz2-sha1):
5276 (xdelta-md5, xdelta-sha1, tgz-size, bz2-size, xd-size, rel-check):

5313 * doc/autoconf.texi (Particular Programs): Mention that
5314 @INSTALL@ and @MKDIR_P@ may vary for different output files.
5315 Reported by Alexandre Duret-Lutz.
5317 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
5319 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
5320 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
5321 Bill Northcott in
5322 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
5324 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
5326 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
5327 pacify insanely picky compilers. Problem reported by Eric Blake.

5330 longer supported by Sun.
5332 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
5334 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
5335 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
5336 -Wundef -Werror". Problem reported by David Fang in
5337 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
5338 * doc/autoconf.texi (Header Templates, Default Includes):
5339 (Particular Functions, Generic Functions, Header Portability):
5340 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
5341 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):
5342 (Present But Cannot Be Compiled, Preprocessor Symbol Index):
5343 Prefer #ifdef to #if.
5344 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prefer #ifdef to #if.

5347 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETVBUF_REVERSED, _AC_FUNC_VFORK):
5348 Likewise.
5349 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):

5351 * lib/autoconf/specific.m4 (AC_DECL_SYS_SYGLIST):
5352 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5353 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
5354 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
5355 this.
5357 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
5359 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
5360 problems with arg script text that doesn't end in newline, and
5361 with '-e a...'. Problems reported by Ralf Wildenhues.
5363 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
5365 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
5366 check for libXt by a check for libX11.
5368 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5371 to last change.
5373 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5375 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
5376 --help' should mention that `--version' outputs configuration
5377 settings. Report by Bruno Haible.
5379 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
5381 Fix test suite failures reported by Pierre in
5382 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
5383 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
5384 the compiler created a file "b.out" when it didn't create anything
5385 at all.
5386 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
5387 Discard stderr too, when invoking the test script.
5389 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
5391 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
5392 in the restoring of the werror flag.
5394 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5396 * doc/autoconf.texi (Volatile Objects): Be even a little
5397 less skeptical about "volatile", after discussion with
5398 Bruno Haible on bug-gnulib.
5399 (Limitations of Usual Tools): Warn about sed stripping
5400 leading white space from text. From Bruno Haible.
5402 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5404 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
5405 compiler complains about it, even if things works after the
5406 complaint. Problem reported by Peter O'Gorman.
5408 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
5409 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
5410 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
5412 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
5414 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
5415 after -R regardless of host. Patrick Welche reports that this
5416 fixes things on NetBSD 3.99.
5418 * NEWS: Recommend M4 1.4.5.
5419 * README: Likewise.
5420 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
5421 * tests/tools.at (autom4te cache): Update wording of diagnostic
5422 to match M4 1.4.5.
5424 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5426 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
5427 under AC_C_VOLATILE.
5428 (Volatile Objects): Be a little less skeptical about what
5429 "volatile" means. Derived from thoughts by Ben Pfaff in
5430 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
5432 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5434 * doc/autoconf.texi: Fix some typos.
5436 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
5438 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5439 more globally, since the 2006-06-30 patch didn't suffice. Problem
5440 reported by Keith Marshall. Also, don't bother with builddir2,
5441 since it shouldn't be needed any more.
5443 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
5445 * doc/autoconf.texi (Generic compiler characteristics):
5446 Document AC_COMPUTE_INT. Fix wrong statements on Default
5447 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
5449 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
5450 (_AC_COMPUTE_INT): Add obsoletion warnings.
5451 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
5452 AC_COMPUTE_INT.
5454 * NEWS: Document change.
5456 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
5458 * doc/autoconf.texi (Volatile Objects): New section.
5460 * NEWS: Document previous change.
5462 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
5464 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
5465 Require that long long int be at least 64 bits wide. C99 requires
5466 this and enough programs depend on it so we should check for it.
5467 Bruno Haible reports in
5468 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
5469 that long long int is 32 bits wide with some nonstandard compilers.
5470 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
5472 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
5474 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
5475 to a nonexistent file, so that we don't have to worry about
5476 a local site configuration that doesn't use /usr/local.
5477 Problem reported by Keith Marshall in
5478 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
5480 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
5482 * doc/autoconf.texi: Be more consistent about using @acronym with
5483 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
5484 quite right (it talked about "OSF/Tru64", even though the
5485 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
5486 and it even mentioned "OSF 4"!) and at this point there's little
5487 reason to talk about OSF any more, since it died in 1994.
5488 (Specific Compiler Characteristics): Simplify example of
5489 negative-size array.
5490 (File Descriptors): Reorder to make the text flow better.
5491 Remove joke about "appreciate the various levels"; I didn't get it.
5492 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
5493 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
5494 (File Descriptors, Limitations of Usual Tools):
5495 Tone down the advice against renaming or removing open files.
5496 (Limitations of Usual Tools): Add a new section, on 'rm'.
5498 2006-06-26 Stepan Kasal <kasal@ucw.cz>
5500 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
5501 -lXt in LIBS, idea from Karsten Hopp; this was due since
5502 this change:
5504 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5505 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5506 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5507 (which belong to Xt, not X itself). See Debian bug 327655.
5509 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5511 * configure.ac (AC_INIT): Bump to 2.60a.
5512 * NEWS: Update.
5514 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5520 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5522 * config/texinfo.tex: Sync from upstream.
5524 * bin/autom4te.in (handle_traces): Transform the `@S|@'
5525 quadrigraph correctly in traces.
5527 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
5528 Fix typos.
5530 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
5531 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
5532 not defined.
5533 * doc/autoconf.texi (Changed Directory Variables): New node,
5534 to document the whole `datarootdir' business a bit better.
5535 * NEWS: Update.
5536 * tests/torture.at (datarootdir workaround): Extend test.
5537 Prompted by report by Alexandre Julliard.
5539 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
5541 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
5542 when using default mode of IBM C 6 for AIX. Problem and two-line
5543 fix reported by Larry Jones.
5545 2006-06-22 Alexandre Julliard <julliard@winehq.org>
5547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
5548 about literal '${datarootdir}' if a definition is found in the
5549 output file.
5551 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
5553 * NEWS: Use "M4" rather than "m4" when appropriate.
5554 Problem reported by Eric Blake.
5555 * doc/autoconf.texi: Likewise.
5556 Use @acronym around BSD, GCC, and GNU when appropriate.
5557 (Why GNU M4): Renamed from "Why GNU m4".
5558 (Redefined M4 Macros): Mention that Posix
5559 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
5560 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
5561 to int.
5563 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5565 * bin/autom4te.in (handle_output): Do not forbid the empty
5566 pattern.
5567 * tests/tools.at (autoconf: the empty token): New test.
5569 2006-06-20 Stepan Kasal <kasal@ucw.cz>
5571 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
5572 calls, so that we do not care whether they are LIFO or FIFO;
5573 in the m4_wrap, do not check which diversion is the topmost
5574 one, just check that the stack is balanced at the end.
5575 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
5576 base diversion forever--pop the previous diversion before
5577 opening the new one; consequently, remove the m4_wrap call.
5578 * lib/autotest/general.m4 (AT_INIT): Likewise.
5579 * tests/m4sugar.at: Do not use
5580 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
5582 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5583 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5585 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
5586 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
5587 Rework example of m4wrap token-pasting trouble so that it doesn't
5588 care whether it's LIFO or FIFO.
5589 Fix some "contrary to"s that are awkward in English.
5591 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5593 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
5594 to `yes' instead of `int$1_t' if the type is found, for more
5595 consistent configure output (where $1 is the number of bits).
5596 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
5597 Suggested by Bruno Haible.
5599 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
5600 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
5601 with system headers. Report by Bruno Haible.
5603 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5605 * config/config.guess, config/config.sub: Sync from upstream.
5607 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
5608 in order to avoid picking up an older installed frozen m4sh.m4f.
5609 Besides an outdated shell startup, this could have been created
5610 by an earlier M4 version with incompatible frozen file format.
5612 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
5614 * README: Recommend m4 1.4.4 instead of 1.4.3..
5615 * doc/autoconf.texi: Likewise.
5616 (Special Chars in Names): Say that $(.FOO) is portable, as
5617 suggested by Stepan Kasal.
5618 (Installation Directory Variables, Build Directories):
5619 (Automatic Remaking, Subdirectories, Fortran Compiler):
5620 (Making testsuite Scripts, Defining Directories):
5621 Quote variable usages better.
5622 (Making testsuite Scripts): Add clean-local rule to makefile
5623 snippet, by Eric Blake.
5624 (Installation Directory Variables): Fix table item font.
5625 Reword slightly to clarify. Generalize advice about
5626 not using special characters to include all file-related
5627 vars, not just VPATH.
5628 (Special Chars in Variables): Warn about special characters in
5629 $(srcdir) too.
5630 (Assignments): Clarify default-value example as suggested by
5631 Ralf Wildenhues in
5632 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
5633 (Special Shell Variables): Note leading ./ or ../, as suggested
5634 by Eric Blake.
5635 (Limitations of Builtins): Under cd, warn about CDPATH.
5636 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
5637 Ralf Wildenhues.
5639 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5641 * doc/autoconf.texi (Configuration Actions): Remove duplicate
5642 `@var', for texi2html.
5643 (Systemology): Some more word wrapping, for DVI output.
5644 (autom4te Invocation): The short option for `--melt' is `-M',
5645 not `-m'.
5647 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
5649 * doc/autoconf.texi: More formatting and English tweaks,
5650 many suggested by Ralf Wildenhues.
5651 Reword to avoid "@code{...}'s" and the like, since it's ugly
5652 with Emacs info mode. discontents -> woes.
5653 Put a few "will"s back. time stamp -> timestamp.
5654 side-effect -> side effect.
5656 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
5658 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
5659 Warn about $@ not persisting. Problem reported by Julien Danjou in
5660 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
5661 (Special Chars in Names): Renamed from Leading _ in Macro Names.
5662 Mention other special chars, too.
5664 2006-06-14 Eric Blake <ebb9@byu.net>
5666 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
5668 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
5670 * doc/autoconf.texi: Some systematic minor improvements, as
5671 follows. Use "makefile" when talking about makefiles
5672 generally (which might be named "makefile" or "Makefile" or even
5673 "foo.mk"), "Makefile" when talking about a specific makefile
5674 called "Makefile". This unclutters the text from weird quotes
5675 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
5676 values" rather than "@var{foo}s" and similar constructs containing
5677 "}s". Use "Make rules" rather than "Makefile rules". Minor
5678 English-language improvements. Change the prefix "sub-" to "sub"
5679 and "re-" to "re".
5680 Put blank lines around examples more consistently.
5681 Avoid "rather" and "very" as intensifiers.
5682 Avoid "will" as an auxiliary.
5683 (Limitations of Make): Split this node into....
5684 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
5685 (Leading _ in Macro Names, Backslash-Newline-Newline):
5686 (Backslash-Newline Comments, Long Lines in Makefiles):
5687 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
5688 (obj/ and Make, make -k Status, VPATH and Make):
5689 (VPATH and Double-colon, $< in Explicit Rules):
5690 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
5691 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
5692 New nodes, resulting from splitup of Limitations of Make.
5693 All cross-references changed. Raise the top node from
5694 a section to a chapter, and all subnodes accordingly.
5695 Redo the introductory wording to match the new organization.
5696 (Installation Directory Variables): Use an example that is
5697 closer to what Autoconf actually does. Mention that VPATH's
5698 value should not contain metacharacters or white space.
5699 (Fortran Compiler): Fix a VPATH bug in an example.
5700 (Leading _ in Macro Names): Mention that this problem is no longer
5701 of practical concern.
5702 (VPATH and Make): Reword the advice to make it clearer
5703 that Autoconf and Automake support VPATH in non-GNU make, but
5704 many packages have bugs in this area.
5705 ($< in Explicit Rules): Refer to Build Directories rather
5706 than using a (non-VPATH-safe) example.
5707 (Automatic Rule Rewriting): Mention the sort of disaster that
5708 can ensue with Solaris-style rule rewriting with VPATH.
5710 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5712 * doc/install.texi (Compilers and Options): Weaken the
5713 suggestion to use GNU make for VPATH builds.
5715 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
5716 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
5718 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
5719 in regular expression.
5721 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5723 * doc/autoconf.texi (Installation Directory Variables):
5724 Drop extra @samp from `@table @samp' item.
5725 (Limitations of Usual Tools): Comment fix.
5726 Do not nest @samp just to point to other table items.
5727 (Writing testsuite.at) <AT_CHECK>: The second argument to
5728 `@dvar' is already @samp'ed.
5729 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
5730 do not use @var in the second argument.
5732 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5734 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
5735 $as_shell.exe too. Problem reported by Andreas Buening in
5736 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
5738 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5740 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
5741 `unused variable' compiler warning, for `-Wall -Werror'.
5742 Reported by Jaap Haitsma in
5743 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
5745 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
5747 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
5748 case the compiler dumps core. Problem reported for
5749 OpenServer 5.0.7 by Tim Rice in
5750 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
5751 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
5752 Likewise.
5754 2006-06-06 Tim Rice <tim@multitalents.net>.
5756 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
5757 "ERROR" only shows up in "make check" output if there is an
5758 error.
5760 2006-06-06 Eric Blake <ebb9@byu.net>
5762 * tests/tools.at (automatically allowed tokens): Fix typo.
5764 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5766 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
5768 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
5769 typically overflows on x86 CPUs, even though the C standard
5770 requires otherwise.
5772 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5774 * configure.ac (AC_INIT): Bump to 2.59e.
5775 * NEWS: Update.
5777 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5779 Version 2.59d.
5781 * config/texinfo.tex: Sync from upstream.
5783 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
5784 seen, invoke libtoolize with `--ltdl' argument.
5785 * lib/autom4te.in (Autoreconf-preselections): Adjust.
5786 * NEWS: Update.
5787 Suggested by Eric Blake.
5789 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5791 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
5792 reported by Ralf Wildenhues.
5793 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
5795 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5797 * THANKS: Update.
5799 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5801 * doc/autoconf.texi: Modernize some of the references to Solaris.
5803 2006-06-05 Stepan Kasal <kasal@ucw.cz>
5805 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
5806 message issued by AC_REQUIRE.
5807 * tests/m4sugar.at: Check m4_require's error message.
5808 * tests/base.at: Check AC_REQUIRE's error message.
5809 * tests/local.at (AT_CHECK_M4): New macro, almost identical
5810 to...
5811 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
5812 AT_CHECK_M4.
5813 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
5814 `expout' as the last parameter.
5815 * tests/tools.at: Adapt to the above change.
5817 2006-06-04 Stepan Kasal <kasal@ucw.cz>
5819 * doc/autoconf.texi (Limitations of Usual Tools): Correct
5820 information about race-free implementations of mkdir.
5822 2006-06-04 Eric Blake <ebb9@byu.net>
5824 * bin/autoreconf.in (help): Document M4 environment variable.
5825 * bin/autoconf.as (Usage): Likewise.
5826 * bin/autom4te.in (help): Likewise.
5827 * doc/autoconf.texi (autom4te Invocation): Likewise.
5829 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
5831 * NEWS: GNU make now recommended for VPATH builds.
5832 Mention that some macros are now documented to be obsolescent.
5833 * doc/autoconf.texi:
5834 Prefer "current" to "modern" to describe
5835 currently-used (albeit perhaps old-fashioned) hosts.
5836 Mention which ancient features no longer need to be worried about.
5837 setgid -> set-group-ID
5838 setuid -> set-user-ID (these are the Posix terms)
5839 Fix some misuses of "only".
5840 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
5841 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
5842 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
5843 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
5844 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
5845 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
5846 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
5847 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
5848 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
5849 Mention that these macros are obsolescent.
5850 (Installation Directory Variables): shall -> should
5851 (File Descriptors): Mention that 0, 1, 2 might get reopened.
5852 Mention that it's now safe to use 3 and 4.
5853 (Limitations of Usual Tools): cp -r is now specified by Posix.
5854 Omit longwinded and obsolescent discussion of cp -f.
5855 Modernize discussion of expr, ls.
5856 (Limitations of Make): Modernize discussion of VPATH builds.
5857 Mention $? as a workaround in some cases.
5858 * doc/install.texi (Basic Installation):
5859 Mention "./configure; make; make install" first. Be more
5860 specific about why this file is generic. Remove unnecessary
5861 parens. Remove misleading "only". Remove obsolete advice
5862 about csh. Don't say "configure" takes awhile; say it
5863 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
5864 and CC=c99 rather than CC=c89, as these are blessed by current
5865 Posix. Recommend GNU make if doing a VPATH build.
5867 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
5869 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
5870 examples involving shell prompts.
5872 2006-06-02 Stepan Kasal <kasal@ucw.cz>
5873 and Paul Eggert <eggert@cs.ucla.edu>
5875 * doc/autoconf.texi (Here-Documents): Add details about the
5876 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
5877 use "here-documents" instead of "here documents".
5879 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5881 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
5883 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
5885 * doc/autoconf.texi (File System Conventions): Warn about ":"
5886 anywhere in directory names.
5888 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5890 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5891 about quoting the case statement, just in case.
5892 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5893 was fixed in ksh93g; reported by Ralf Wildenhues.
5895 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5897 * doc/autoconf.texi (System Services): Do not document
5898 overriding EXEEXT via ac_cv_exeext=ext.
5899 (Particular Programs) <AC_PROG_MKDIR_P>:
5900 Document that ${MKDIR_P} understands --.
5901 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5902 comment.
5904 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5906 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5907 argument with leading hyphen. Problem reported by Paul Eggert.
5909 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5911 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5912 about quoting ac_try: quote all of it, if any of it seems suspicious.
5913 This means we don't have to worry about ${ or sed any more.
5914 Also, double-quote the case statement, to work around misuses via
5915 underquoting as reported by Ralf Wildenhues in
5916 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5917 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5918 undocumented and dangerous macro.
5919 Problem reported by Ralf Wildenhues in
5920 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5922 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5924 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5925 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5926 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5928 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5930 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5931 since evidently some packages rely on the old, broken behavior.
5932 Problem reported by Ralf Wildenhues in
5933 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5934 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5935 pre-2006-05-26 definitions, but leave in the comments that
5936 these macros are dangerous and should not be used.
5937 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5938 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5939 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5940 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5941 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5943 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5945 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5946 the use of 'tr', since this is our only use of 'tr'.
5948 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5949 and Paul Eggert <eggert@cs.ucla.edu>
5951 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5952 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5954 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5956 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5957 the output file in the `${datarootdir}' test.
5959 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5960 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5962 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5963 mention of `datarootdir' in the input file(s), but literal
5964 `${datarootdir}' in the output file, and we haven't warned yet,
5965 then warn as well: the user may have (erroneously) used
5966 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5967 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5968 * tests/torture.at (datarootdir workaround): Extend this test.
5969 * NEWS: Update.
5971 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5972 and Paul Eggert <eggert@cs.ucla.edu>
5974 * doc/autoconf.texi (autoheader Invocation): The first argument to
5975 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5976 alternatives and clear up the language a bit.
5978 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5980 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5981 ac_config_guess, ac_config_sub, ac_configure.
5982 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5983 Fix typo that prevented an unnecessary space from being removed.
5984 Problems reported by Ralf Wildenhues in:
5985 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5987 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5989 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5990 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5991 Don't use the term "thread-safe" to talk about mkdir race
5992 conditions, since the problem is more a process than a thread
5993 issue. Problem reported by Stepan Kasal in:
5994 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5995 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5996 the test for 'install' more closely. Look at MKDIR_P first.
5997 Look in the PATH, and at /opt/sfw/bin.
5998 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5999 Don't bother to try mkdir -p, since we already check mkdir --version;
6000 just look at the version number. (There's no easy way to check
6001 for race-free implementations.)
6002 * tests/tools.at (autoconf: subdirectories): Adjust to above
6003 changes, since MKDIR_P now might end in "/mkdir -p".
6005 * doc/autoconf.texi (autoheader Invocation): Mention that the
6006 first arg of AC_DEFINE_UNQUOTED must be a literal.
6007 Problem reported by Ben Pfaff in
6008 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
6010 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
6011 * doc/autoconf.texi (Special Chars in Variables): New section.
6012 (Preset Output Variables): Warn about special chars in CPPFLAGS.
6013 (Installation Directory Variables): Quote $(datadir) better.
6014 (Limitations of Builtins): Describe some of eval's trickiness.
6016 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
6017 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
6018 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
6019 in front of every arg, not just trailing args. Quote apostrophes.
6020 (_AC_EVAL_ECHO): New macro.
6021 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
6022 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
6023 removed.
6024 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
6025 exposed by quoting of eval argument. Put the command on line line
6026 so it logs better.
6027 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
6028 (_AC_PATH_X, AC_PATH_X): Quote more safely.
6029 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
6030 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
6031 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
6032 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
6033 Use eval more safely.
6034 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
6035 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
6036 to be replaced.
6037 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
6038 lines, exposed by quoting of eval argument.
6040 2006-05-26 Stepan Kasal <kasal@ucw.cz>
6041 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6043 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
6044 initialization of `ac_cv_exeext', do not override it if it was
6045 already set, unless it was set to `no', for compatibility with
6046 Autoconf-2.13, and comment this.
6047 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
6048 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
6049 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
6050 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
6051 Document that this test may be overridden by setting
6052 `ac_cv_exeext'.
6054 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6056 Revert these two patches:
6058 2006-04-06 Eric Blake <ebb9@byu.net>
6059 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6060 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6061 2006-04-01.
6063 2006-04-01 Stepan Kasal <kasal@ucw.cz>
6064 Clean up _AC_COMPILER_EXEEXT* macros.
6065 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6066 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6067 ac_file to the name of the default output file and call
6068 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6069 initial `rm' of the candidate files...
6070 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6071 the same list in subsequent `rm' calls, and for the temporary
6072 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6073 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6074 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6075 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6076 no longer needed) by libtool. Make it a cache check.
6077 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6078 copied here by mistake.
6079 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6080 _AC_COMPILER_EXEEXT.
6081 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
6082 _AC_COMPILER_OBJEXT directly.
6083 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6085 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6087 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
6088 Fix description of how the buggy `sed' works.
6090 2006-05-25 Noah Misch <noah@cs.caltech.edu>
6092 Sync from Automake:
6094 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
6095 ENOLCK. Only mention `make -j' when applicable. Only raise
6096 fatal errors when `make -j' is involved. Improve error message.
6098 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6100 * doc/autoconf.texi (Here-Documents): We now know more about
6101 the variable expansion in here documents bug.
6102 Thanks to Tim Rice and Stepan Kasal.
6104 * doc/autoconf.texi (Making testsuite Scripts): Add an example
6105 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
6107 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6109 * tests/autotest.at (Multiline command from M4 expansion):
6110 No failure to be expected if the shell quotes newlines in
6111 commands in the `set -x' output. Report by Tim Rice.
6112 * THANKS: Update.
6114 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6116 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
6117 expansion in the here-documents used by config.status, as that
6118 runs afoul of the Korn shell version M-12/28/93d bug described in
6119 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
6120 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
6121 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
6123 2006-05-23 Jim Meyering <jim@meyering.net>
6125 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
6126 Fix typo introduced with 2006-04-02 change. It reversed the sense
6127 of the test.
6129 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
6131 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
6132 ac_dB slightly, to save bytes in the script.
6133 Max out at 50 lines, rather than 96; this is more likely
6134 (though not guaranteed) to avoid obscure 'sed' failures.
6136 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6138 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
6139 `tr -d -' as bad option argument. Work around this by deleting
6140 an unrelated character.
6141 Report by Tim Rice <tim@multitalents.net>.
6143 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
6144 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
6145 Stepan Kasal <kasal@ucw.cz>
6147 * doc/autoconf.texi (Particular Programs): Do not promise that
6148 we always prefer the GNU version of the program, and that we
6149 search according to PATH; both rules can have exceptions.
6150 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
6151 AC_PROG_SED. Move descriptions of limitations
6152 to the Limitations of Usual Tools section.
6153 (Limitations of Usual Tools) <sed>: Mention script length
6154 limitations with Solaris /usr/ucb/sed.
6155 <grep>: Fix wording for empty alternative. Mention that -c and
6156 -l should not be combined, and that -E and -F should not be
6157 combined.
6159 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6160 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6162 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
6163 limits in Solaris 8 /usr/ucb/sed by testing a long script.
6165 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6167 * doc/autoconf.texi (Defining Symbols): Literal parameter of
6168 AC_DEFINE is now passed to m4_pattern_allow.
6169 * NEWS: Mention that; likewise for AC_SUBST.
6170 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
6171 the parameter to m4_pattern_allow.
6172 * tests/tools.at: Add a check for that.
6174 2006-05-22 Stepan Kasal <kasal@ucw.cz>
6176 * lib/autoconf/status.m4: Fix typos.
6178 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6180 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
6181 only the files that this macro generates.
6183 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6185 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
6186 the HP-UX sed limitation of 99 commands, labels do not count.
6187 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
6188 in the comment.
6189 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
6191 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
6193 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6194 Import the following fix from coreutils:
6196 2006-01-13 Jim Meyering <jim@meyering.net>
6198 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
6199 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
6200 not double-quote uses of that variable, to accommodate the rare
6201 case in which getmntent is available in none of the libraries
6202 checked. This happens at least on FreeBSD 5.0.
6204 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6206 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
6207 ac_config_guess, ac_config_sub, and ac_configure, since evidently
6208 some other programs unwisely rely on these undocumented vars.
6209 But put in warning comments about them.
6210 Problem reported by Ralf Wildenhues in
6211 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
6212 * NEWS: Document that these variables are intended to go away.
6214 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6216 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
6217 and set the language to C++ (analogous to the equivalent Fortran
6218 tests).
6220 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
6221 * doc/autoconf.texi (C++ Compiler): Document it.
6222 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
6223 * NEWS: Update.
6225 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6227 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
6228 that caused config.status to generate 100-command sed scripts; the
6229 portable limit is 99.
6231 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6233 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
6234 variable `ac_d' instead of `d' to avoid infringing namespace.
6235 Report by Ralf Menzel.
6237 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
6239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
6240 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
6241 * tests/tools.at (autoconf: subdirectories): New test, taken from
6242 the corresponding problem report by Ralf Wildenhues in:
6243 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
6245 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
6246 Quote some uses of shell variables if they might suffer unexpected
6247 globbing. This doesn't fix all instances of quoting problems that
6248 I found, just the easy ones that look safe.
6249 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
6250 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
6251 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
6252 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
6253 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
6254 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6255 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
6256 Likewise.
6257 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
6258 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
6260 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6262 * bin/autoreconf.in ($help): Reword according to the manual.
6263 Suggested by Olly Betts.
6265 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
6266 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6268 * bin/autoreconf.in: Pass the directory argument to
6269 `require_configure_ac'. Fix comment.
6270 * tests/torture.at (Configuring subdirectories): Expose this.
6271 Reported by Olly Betts.
6273 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6275 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
6276 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
6277 Automake as follows:
6279 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
6280 `$configure_in' instead of `configure.in', to preserve
6281 directory component.
6283 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6285 * config/config.guess, config/config.sub, config/texinfo.tex,
6286 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
6288 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6290 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
6291 test for C99 conformance; (bool) 0.5 is an integer constant
6292 expression, but (bool) -0.5 is not. Problem reported by Fedor
6293 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
6295 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6297 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
6298 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
6299 Warn about obsolete install-sh files. Remove stray sentence
6300 fragment and fix cross reference.
6301 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
6302 install -d; this undoes the 2006-05-10 change.
6303 (MKDIR_P): Mark with AN_MAKEVAR.
6304 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
6305 that we don't require $INSTALL to be thread-safe. Move comments
6306 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
6307 of AC_PROG_INSTALL. Output a message saying that we're checking
6308 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
6309 MKDIR_P instead of AC_SUBST.
6310 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
6311 Special magic for MKDIR_P, too.
6312 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
6313 a dnl.
6314 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
6316 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6318 Sync from Automake, as follows:
6320 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6321 * config/install-sh: Initialize IFS, so field splitting isn't
6322 turned off later.
6323 * config/mkinstalldirs: Likewise.
6324 * config/missing: Remove superfluous quotes. Replace all uses of
6325 `[' by `test', for consistency, and for..
6326 * config/missing (sed_minuso, sed_output): New variables.
6327 (autom4te, help2man, makeinfo): Use them. Unifies detection of
6328 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
6329 Fixes `missing' to detect `--output' for help2man. Fixes
6330 PR automake/483. Report by Dennis J. Linse.
6331 (autom4te): Document in `missing --help'.
6333 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6335 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
6336 * config/install-sh: Don't use 'path' to talk about file names,
6337 as per GNU coding standards. Close a race condition reported by Ralf
6338 Wildenhues and Stepan Kasal. There is still a race condition
6339 on hosts that predate Posix 1003.1-1992, but we can't help this.
6340 Don't mishandle weird characters like space on pre-Posix hosts.
6341 Invoke mkdir at most once per dir arg on pre-Posix hosts.
6342 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
6343 AC_PROG_MKDIR_P from AS_MKDIR_P.
6344 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
6345 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
6346 earlier editions are not (including Automake 1.8.3).
6347 Do not suggest mkinstalldirs for thread-safety.
6348 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
6349 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
6350 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
6351 presence of special characters and race conditions.
6352 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
6353 in Autoconf's name space.
6355 2006-05-10 Bruno Haible <bruno@clisp.org>
6356 and Paul Eggert <eggert@cs.ucla.edu>
6358 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
6359 from Automake with minor changes.
6360 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
6362 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
6364 * config/install-sh: Update to Automake CVS version, as follows:
6365 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6366 * lib/install-sh: Simplify the expr implementation of dirname.
6367 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
6368 * lib/install-sh: Handle --, and diagnose unknown options.
6370 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6372 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
6373 `./autom4te' to create `./testsuite', since the `all' target
6374 will ensure its presence, but `installcheck' should not create
6375 the uninstalled wrappers.
6377 * tests/torture.at (Unusual Automake input files): Skip if we
6378 detect automake < 1.8.
6380 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6382 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
6383 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
6384 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
6385 * NEWS: Update.
6387 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6389 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
6390 munge (multiple) white space and other oddities.
6391 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
6392 single quotes in variable assignment.
6393 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
6394 and similar failures by adding multiple spaces, tabs, and other
6395 special characters.
6396 Report and different test suggested by Francesco Romani
6397 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
6399 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
6400 single quotes, we only need to search for single quotes; this
6401 both simplifies the search pattern, and makes us less
6402 susceptible to `echo' variations for arguments not containing
6403 single quotes.
6404 (_AC_ARG_VAR_VALIDATE): Likewise.
6406 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6408 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
6409 `$*' and IFS concatenation issue with traditional shells and
6410 bash-2.04. Report by Seanster@Seanster.com.
6412 2006-05-03 Bruno Haible <bruno@clisp.org>
6414 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
6415 precisely which Mac OS X versions have the od problem.
6417 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6419 * doc/autoconf.texi: Use @option systematically.
6421 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
6422 and Bruno Haible <bruno@clisp.org>
6424 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
6425 about 'od'.
6426 (Integer Overflow): Mention the special case of integer division
6427 overflow.
6429 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6431 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
6432 traditional shells like the Solaris one that do not use the
6433 first IFS character for assembling `$*'.
6434 Prompted by a related report from autoconf_bug@nro.ca.
6436 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
6437 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6439 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
6440 Mention more problems with the -e option.
6442 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6444 * NEWS: Typo.
6445 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
6447 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
6448 in URLs to improve DVI formatted output (requires texinfo 4.6).
6449 (System Services, Systemology, Shellology): Likewise.
6450 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
6451 output.
6453 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
6454 continuous text.
6455 (Runtime): Fix macro argument names to match description:
6456 `action-if-found' -> `action-if-true' and similarly.
6457 (Obsolete Macros): Likewise.
6458 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
6459 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
6460 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
6462 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6464 * doc/autoconf.texi (Limitations of Make): Clean up markup.
6466 * ChangeLog: Typo.
6467 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
6468 DVI output.
6470 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6477 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
6479 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
6480 (Integer Overflow, Null Pointers, Buffer Overruns):
6481 (Floating Point Portability, Exiting Portably): New sections.
6482 (Writing Test Programs): Fix some langauge. Recommend exiting
6483 with status 1, not merely nonzero. Clarify exit declaration.
6484 (Run Time): Move C exit status stuff to new Exiting Portably section.
6485 (Systemology): Mention Posix and levenez. Update v7 reference.
6486 (Portable Shell): Mention the Posix shell.
6488 2006-04-25 Stepan Kasal <kasal@ucw.cz>
6490 * bin/autoconf.as (me): Replace by as_me.
6492 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6494 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
6495 since as_me isn't set yet.
6497 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6499 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
6500 a few minor bugs in this area.
6502 * doc/autoconf.texi (Programming in M4sh): Comment out the
6503 documentation of AS_BASENAME, for now.
6504 (Shell Substitutions): Do not use AS_DIRNAME in an example.

6508 (dir): Remove the unused variable.
6509 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
6510 AS_DETECT_REQUIRED. All uses changed.
6511 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
6512 All uses changed.
6513 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
6514 (AS_BASENAME): Use "basename --" to protect against leading "-".
6515 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
6516 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
6517 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
6518 (_AS_DIRNAME_PREPARE): Likewise.
6519 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
6520 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
6521 (AS_DIRNAME): Use "dirname --".
6523 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
6525 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
6526 of "run time" and "run-time" changed to "runtime", for consistency.
6527 * lib/autoconf/fortran.m4: Likewise (in comment).
6528 * lib/autoconf/functions.m4: Likewise.
6529 * lib/autoconf/general.m4: Likewise.
6530 * lib/autoconf/headers.m4: Likewise.
6532 * doc/autoconf.texi (Run Time): Document the exit status situation
6533 with more accuracy and detail.
6535 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6537 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
6538 Archive is not officially `GNU' any more. Update URL.
6539 (Defining Directories): Likewise
6540 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
6542 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6544 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
6545 newline from the `trap' code to finish `config.log'; the NetBSD
6546 /bin/sh resets the exit status after an empty command, as
6547 documented in doc/autoconf.texi.
6548 Reported by Dalibor Topic <robilad@kaffe.org>.
6550 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
6552 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
6553 Suggested by Bruno Haible.
6555 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
6557 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
6558 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
6559 Instead, just list the shells that we know work.
6560 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
6561 changed. Be more cautious about the _cv_ variable.
6562 * tests/tools.at (Syntax of the shell scripts): Check the
6563 _cv_ variable once, at first, to avoid an internal autoconf error
6564 when sh -n does not work.
6566 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6568 * lib/Autom4te/FileUtils.pm: Sync from Automake.
6570 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
6572 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
6573 use ">&-" since we're only 99.999% sure that this is portable,
6574 and since the MinGW bug is fixed in a different way.
6575 * lib/autotest/general.m4 (AT_INIT): Likewise.
6577 2006-04-16 Stepan Kasal <kasal@ucw.cz>
6579 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
6580 before opening config.log, to avoid hitting a bug on MinGW.
6582 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
6584 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
6585 AS_MESSAGE_LOG_FD before reopening it onto the log file.
6586 This works around a MinGW bug reported by Eric Paire.
6587 Make sure that all writes to the log file append to it,
6588 rather than possibly losing data.
6589 * lib/autotest/general.m4 (AT_INIT): Likewise.
6591 2006-04-14 Stepan Kasal <kasal@ucw.cz>
6593 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
6594 description.
6596 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6598 * NEWS: Update.
6600 * configure.ac (AC_INIT): Bump to 2.59d.
6602 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6604 Version 2.59c.
6606 * Makefile.maint (news-date-check): Do not require a leading `*'
6607 before the release date in NEWS.
6609 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6610 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6612 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
6613 the instantiated file do not contain the string 'datarootdir'
6614 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
6615 @mandir@, replace the reference '${datarootdir}' by the value.
6616 * tests/torture.at (datarootdir workaround): New test.
6617 * NEWS: Advertise this temporary fixup.
6618 Based on a patch by Bruno Haible, reported and analyzed by
6619 Paul Eggert and Noah Misch.
6621 2006-04-12 Eric Blake <ebb9@byu.net>
6623 * tests/autotest.at (Debugging a failed test): Fix comment.
6625 2006-04-12 Stepan Kasal <kasal@ucw.cz>
6627 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
6628 all the changes since 2006-04-07.
6630 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6632 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
6633 succeeded, but `ln -s file dir' failed, take care to remove the
6634 leftover target before the next test, to prevent its spurious
6635 failure; also make sure `ln file dir' works before selecting it.
6636 Thanks to Keith Marshall for pointing this out.
6637 * THANKS: Update.
6639 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
6640 assignments in `at_debug_args', so that we put them correctly
6641 in the `run' script.
6642 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
6643 Reported by Eric Blake.
6645 2006-04-11 Eric Blake <ebb9@byu.net>
6647 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
6648 top-level tests after micro-suite has been run. Used in...
6649 (Debugging a successful test, Debugging script and environment),
6650 (Debugging a failed test): ...these new tests. The first of these
6651 is fixed by...
6652 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
6653 macro, split out from...
6654 (AT_INIT): ...here, so that using -d also generates a run script.
6655 Document that -d inhibits top-level logging.
6656 * doc/autoconf.texi (testsuite Invocation): Document that -d only
6657 inhibits top-level logging; debug scripts are created.
6659 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
6660 check.
6661 * tests/autotest.at (Empty test, Empty check): New test to check it.
6663 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
6664 from gcc.
6666 2006-04-10 Stepan Kasal <kasal@ucw.cz>
6668 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
6669 the files if a problem appears. Make the empty *.at files
6670 read-only, too. Proposed by Ralf Wildenhues.
6672 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6674 * config/Makefile.am: Add comment to force updated Makefile.in.
6676 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
6677 space only patch to this file, this patch causes the Makefile.in
6678 files that include freeze.mk to be updated, and thus have a
6679 newer time stamp again, which in turn makes a pristine CVS
6680 checkout have correct time stamps.
6682 * Makefile.maint (cvs-sv): New macro, to be used..
6683 (config.guess-url_prefix, config.sub-url_prefix)
6684 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
6685 point to CVS text checkout of Gnulib files.
6686 (copyright-check): Bump current year.
6687 (announcement): Do not hard-wire `./announce-gen'.
6688 (cvs-update): Propagate failures of `cvs' and `move-if-change'
6689 correctly.
6690 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
6691 `chmod +x'.
6692 (wget_files): Update config.guess, config.sub, texinfo.tex by
6693 `wget-update', now that their URLs work again.
6695 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6697 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
6698 Problem noted by Paul D. Smith.
6700 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6702 * doc/autoconf.texi: Remove unused words from word list.
6703 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
6704 .x-sc_trailing_space: New files.
6706 * doc/standards.texi: Sync from gnulib.
6708 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
6709 `LIBOBJDIR' as experimental.
6711 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
6712 with a target directory; it's internally implemented as `cp'
6713 anyway, but since Autoconf advertises the possibility to use
6714 a target directory when LN_S is `ln -s', we need to find out.
6715 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
6716 analyzed by Keith Marshall <keith.marshall@total.com>.
6718 * THANKS: Update.
6720 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
6722 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
6723 confdefs.h as-is. In general, if it has backslash-newline or the
6724 like, then it doesn't work either to sort or to remove empty
6725 lines.
6727 2006-04-09 Stepan Kasal <kasal@ucw.cz>
6729 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
6731 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
6733 * lib/autom4te.in (Automake-preselections): Preselect
6734 _AM_SUBST_NOTMAKE.
6736 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6738 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
6739 apostrophe within a single-quoted string, as this is the usual
6740 tradition and is easier to read than '"'"'. Don't rely on the
6741 shell treating "$/" like '$/'. Use a more-consistent indenting
6742 style for the trap.
6744 2006-04-09 Eric Blake <ebb9@byu.net>
6746 * tests/autotest.at (Backquote command substitution),
6747 (Multiline backquote command substitution): Remove mistaken
6748 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
6749 applied...
6750 (Parenthetical command substitution, Multiline parenthetical
6751 command substitution): here.
6753 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
6755 Import macros from gnulib (often changing their name).
6757 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
6758 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
6759 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

6769 (Pointers): Add Gnulib URL.
6770 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
6771 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
6772 Gnulib section.
6773 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
6774 suggest a #define rather than a typedef for _Bool, and mention
6775 Gnulib rather than trying to substitute stdbool code.
6776 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
6777 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
6778 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
6779 AC_STRUCT_DIRENT_D_TYPE.
6780 (Particular Types): Mention stdint.h and inttypes.h as standard
6781 headers too.
6782 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
6783 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
6784 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
6785 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
6786 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
6787 (C Compiler): Move AC_C_LONG_DOUBLE to ...
6788 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
6789 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
6790 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
6791 (Coding Style). Don't mention m4_expand_once.
6792 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
6793 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
6794 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
6795 (AC_CHECK_FUNCS): Use it.
6796 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
6797 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
6798 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
6799 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
6800 (AC_HEADER_ASSERT): New macro.
6801 (AC_HEADER_STDBOOL): Don't assume "#error" works.
6802 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
6803 Catch a bug in an HP-UX C compiler.
6804 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
6805 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
6806 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
6807 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
6808 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
6809 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
6810 New macros.
6812 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
6813 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
6815 2006-04-08 Stepan Kasal <kasal@ucw.cz>
6817 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
6818 of the warning introduced by the 2001-08-28 change.
6820 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
6821 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6823 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
6824 variables shall be overriden by the cache.
6825 * tests/torture.at (AC_ARG_VAR): Test also with a first value
6826 that contains braces.
6828 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6830 Revert the patch from 2006-04-01 and only improve
6831 _AS_DETECT_BETTER_SHELL:
6833 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
6834 skip nonexistent directories.
6835 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
6836 only shell candidates which exist.
6837 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
6838 * lib/autotest/general.m4 (AT_INIT): No need to give three
6839 parameters to _AS_PATH_WALK.
6841 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
6842 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6844 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
6845 distinguish m4sugar macros.
6846 * tests/tools.at (autoupdating with aclocal and m4_include):
6847 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
6848 test case by Noah Misch <noah@cs.caltech.edu>.
6850 2006-04-07 Stepan Kasal <kasal@ucw.cz>
6852 Revert my change from 2006-03-17, in other words:
6853 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
6854 and DUALCASE=1.
6855 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
6856 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
6857 it is set.
6859 2006-04-07 Eric Blake <ebb9@byu.net>
6861 * doc/autoconf.texi (Programming in M4sh): Document that
6862 AS_MKDIR_P exits the script on failure.
6863 * lib/autotest/general.m4: Remove redundant AS_ERROR.
6865 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6867 * config/elisp-comp, config/install-sh, config/mdate-sh,
6868 config/missing, config/mkinstalldirs: Sync from Automake.
6870 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
6871 from Automake.
6873 * doc/make-stds.texi: Sync from gnulib.
6875 2006-04-06 Eric Blake <ebb9@byu.net>
6877 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
6878 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
6879 2006-04-01.
6881 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
6882 Eric Blake <ebb9@byu.net>,
6883 Paul Eggert <eggert@cs.ucla.edu>,
6884 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6886 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6887 whether `set' quotes correctly: redirect stderr of the tested
6888 `set', and use a subshell, for Ultrix; use `sed' instead of
6889 `grep' for zsh `set' which may write binary output; match only
6890 at the beginning of a line, to avoid false positives.
6891 In order to avoid false positives by unrelated variables with
6892 multiline content, put the dump algorithm in a subshell and
6893 unset all variables containing newlines (except some which are
6894 special to the shell). Warn about cache variables that are
6895 unset.
6897 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6899 * config/config.guess, config/config.sub, config/texinfo.tex:
6900 Sync from upstream.
6902 * tests/mktests.sh: Reword comments.
6904 * tests/mktests.sh: Only skip internal macros starting with
6905 `_AC_' or `__AC_'. Noted by Stepan Kasal.
6906 Update exclusion lists for the test suite to this end:
6907 (AC_ARG_VAR): Do test this now.
6908 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
6909 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
6910 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
6911 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
6913 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
6914 shell issue with double-quoted command substitutions of native
6915 commands.
6916 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
6917 Marshall.
6919 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
6920 no file matches the glob, discard the warning, set `nullglob'.
6921 (syntax-check): Likewise.
6922 (sc_cast_of_x_alloc_return_value): Likewise.
6923 (sc_cast_of_alloca_return_value, sc_error_exit_success)
6924 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
6925 (m4-check): Likewise.
6926 (sc_system_h_headers): Do not print rule on execution.
6927 (sc_tight_scope): Do not fail for non-existing `src' directory.
6928 (sc_changelog): Skip the Copyright footer.
6929 * lib/autoconf/lang.m4: Remove trailing space.
6931 * lib/autoconf/status.m4: More replacements to
6932 <tab><space> where this makes sense.
6934 2006-04-06 Stepan Kasal <kasal@ucw.cz>
6936 * tests/Makefile.am (maintainer-check-posix):
6937 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
6939 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
6940 ac_config_<foo>s again, sometimes normalized, sometimes not.
6941 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
6942 (AC_CONFIG_COMMANDS): Do not do so here.
6943 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6944 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6945 2005-07-25 rewrite. Noticed by Noah Misch.
6947 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

7101 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7102 initial `rm' of the candidate files...
7103 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7104 the same list in subsequent `rm' calls, and for the temporary

7107 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7108 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7109 no longer needed) by libtool. Make it a cache check.
7110 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
7111 copied here by mistake.
7112 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
7113 _AC_COMPILER_EXEEXT.
7114 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

7151 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
7152 * doc/autoconf.texi (autoreconf Invocation): Document it.

7241 checked for existence, so we don't barf over a nonexisting
7242 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
7244 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7866 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
7867 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
7868 code so that the most common case requires less forks.
7870 2005-10-20 Stepan Kasal <kasal@ucw.cz>
7872 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
7873 not portable; thanks to Paul Eggert and Alexandre.
7875 * NEWS: Fix an old typo.
7877 2005-10-20 Jim Meyering <jim@meyering.net>
7879 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
7880 the latter'', in two places.
7882 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
7884 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
7885 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7886 the inner workings of AC_LANG_FUNC_LINK_TRY.
7887 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7888 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7889 by the function rather than ignoring it.
7890 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7891 comparing its address. Intel's interprocedural optimization was
7892 outsmarting the old heuristic. Problem reported by
7893 Mikulas Patocka.
7895 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7897 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7899 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7901 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

7904 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7906 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7907 before removing it (chmod -R u+rwx); there are three instances of this.
7909 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7910 Stepan Kasal <kasal@ucw.cz>
7912 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7913 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7914 make its content writable before removing it. Remove an errorneous
7915 comment from the end, where the logs of the failed tests are copied
7916 to the main log file.
7918 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7920 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7921 in case the computer is too quick. Double quote the configure.ac
7922 snippets.
7924 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7925 problems if the testsuite were running too fast.
7927 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7929 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7930 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7931 (which belong to Xt, not X itself). See Debian bug 327655.
7932 * NEWS: Mention this.
7934 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7936 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7938 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7940 * config/move-if-change: Don't output "$2 is unchanged";
7941 suggested by Ben Elliston. Handle weird characters correctly.
7943 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7945 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7946 calls, so that the final expansion of this macro is shorter.
7947 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7948 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7949 the cleanup there. Use AS_VAR_* macros, to be more general.
7950 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7952 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7954 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7956 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7958 * doc/autoconf.texi (Configuration Headers): Add an index entry
7959 for AH_HEADER.
7961 2005-08-26 Pavel Roskin <proski@gnu.org>
7963 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7964 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7965 running xmkmf.
7967 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7969 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7970 The previous patch didn't work, so try a better one.
7972 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7974 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7975 in the example. Reported by Bruno Haible.
7976 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7977 "if $undefined_var;" succeeds with my shell.
7979 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7980 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7981 but change the m4_divert_text to m4_divert_once.
7983 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7985 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7986 Work around bug in Solaris /usr/xpg4/bin/awk.
7987 The bug is present in at least Solaris 8 through 10.
7989 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7991 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7992 some evil values and relying on the fact that $* concatenates the
7993 parameters by the first character from IFS.
7995 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7996 Stepan Kasal <kasal@ucw.cz>
7998 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7999 first header appears, define AH_HEADER.
8000 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
8001 Update limitations about when to call AC_CONFIG_HEADERS.
8002 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
8003 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
8004 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
8005 ``Configuration Actions''; fix their index entries.
8007 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
8008 options correctly. Process N-M as M-N if M is smaller than N.
8009 Process ranges correctly so that N-N will run only N.
8010 Sort and uniquify the tests that will be run. If there is more
8011 than one test, reinsert the banners for the tests.
8012 * tests/autotest.at (Keywords): Unmark XFAIL.
8014 2005-08-23 Stepan Kasal <kasal@ucw.cz>
8016 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
8017 before passing the macro name to AH_TEMPLATE.
8019 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
8020 now opens log after option processing; in particular, --version
8021 and --help do not touch config.log.
8023 * Makefile.maint: Revert the change from 2005-08-12.
8025 2005-08-22 Stepan Kasal <kasal@ucw.cz>
8027 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
8028 common code to...
8029 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
8031 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8033 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
8034 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
8035 Language cleanup.
8037 * doc/autoconf.texi (Defining Symbols, Changed Results):
8038 Prepend to LIBS, not append, in examples.
8040 2005-08-16 Stepan Kasal <kasal@ucw.cz>
8042 When building in place, set srcdir="."; suggested by Tim Van Holder.
8044 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
8045 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
8046 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
8047 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
8048 does not mean "no --srcdir option".
8050 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8052 * tests/autoscan.at (autoscan): New file.
8053 * tests/suite.at: Use it.
8054 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
8055 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
8057 * tests/autotest.at (Keywords): Test keywords combinations.
8059 2005-08-12 Stepan Kasal <kasal@ucw.cz>
8061 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
8062 add "2>&1"; gzip 1.2.4 prints help on stderr.
8064 2005-07-27 Stepan Kasal <kasal@ucw.cz>
8066 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
8067 was pushdef'ed twice while popped only once. Push it only once.
8068 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
8070 2005-07-26 Stepan Kasal <kasal@ucw.cz>
8072 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
8073 prefixed by mere "===", not "configure: === ".
8075 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
8077 * Makefile.maint: Update from Bison.
8079 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
8080 "<tab>" in comment, so that the point is understandable.
8082 2005-07-25 Stepan Kasal <kasal@ucw.cz>
8084 Rewrite substantial part of lib/autoconf/status.m4.
8085 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
8086 and CONFIG_COMMANDS are not processed in four separate loops.
8087 Instead, there is one main loop. This alows that the common code
8088 is expanded only once, thus config.status (and configure) is smaller.
8090 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
8091 the AC_LIST_FILES and cousins macros are no longer used.
8093 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
8094 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
8095 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
8096 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
8097 contain the initialization, nor the for loop, nor the associated
8098 commands; all these go to ...
8099 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
8100 _AC_OUTPUT_CONFIG_STATUS.
8101 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
8102 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
8103 (_AC_OUTPUT_FILE): The creation of the sed script ...
8104 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
8105 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
8106 _AC_OUTPUT_MAIN_LOOP.
8107 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
8108 _AC_CONFIG_COMMANDS): Use ...
8109 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
8110 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
8111 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
8112 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
8113 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
8114 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
8115 ... new macros.
8116 (_AC_CONFIG_UNIQUE): Update.
8117 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
8118 Replaced by this ...
8119 (_AC_LIST_TAGS): ... new common macro.
8120 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
8121 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
8122 (_AC_LIST_TAG_COMMANDS): ... new common macro.
8123 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
8124 this didn't belong to the `config commands' section.
8125 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
8126 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
8127 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
8128 to the `config commands' section either.
8129 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
8130 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
8132 ... and many changes to the comments nearby.
8134 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
8135 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
8136 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8137 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
8138 (#define header templates): The comment at the top of the generated
8139 header now includes the name(s) of the source file(s).
8141 Several unrelated small changes:
8143 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
8144 parameter to AC_DIAGNOSE.
8145 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
8146 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
8147 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
8148 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
8149 with AU::AC_OUTPUT.
8150 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
8151 in AC_OUTPUT doesn't double-quote it either.
8152 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
8153 parameters.
8155 2005-07-10 Stepan Kasal <kasal@ucw.cz>
8157 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
8158 versions of Portland Group compiler produce single- and double-quoted
8159 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
8160 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8162 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8164 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8165 This is a corrected version of yesterday's patch.
8167 2005-07-07 Stepan Kasal <kasal@ucw.cz>
8169 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
8170 path, too; insert a "===" to emphasize the line.
8172 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
8173 ac_cv_build_alias to ac_build_alias.
8174 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
8176 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
8177 change eliminates it. Problem reported by Alexandre Duret-Lutz.
8178 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
8179 (AC_ARG_VAR): ... here.
8180 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
8181 target_alias.
8183 Keep a list of all precious variables and process them with one simple
8184 for loop, instead of expanding all commands, or, OTOH, complicated
8185 processing of output of "set".
8186 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
8187 variable names in new macro...
8188 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
8189 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
8190 a loop to assign all ac_env_* and ac_cv_env_* variables.
8191 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
8192 to INIT_PREPARE.
8193 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
8194 its value to shell variable ac_precious_vars and call
8195 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
8196 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
8197 _AC_ARG_VAR_VALIDATE.
8199 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
8200 and the AC_SUBSTs ...
8201 (AC_INIT): ... here.
8203 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
8204 the ac_subst_files section in config.log.
8206 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
8208 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

8213 * tests/c.at (C keywords): Test AC_C_TYPEOF.
8215 Fix problems reported by Nicolas Joly.
8216 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
8217 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
8218 They are generated by the Tru64 v5.1B shell.
8220 2005-07-05 Stepan Kasal <kasal@ucw.cz>
8222 Fix my changes from 2005-07-01; reported by Noah Misch.
8223 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
8224 description, the macro now accepts only a single tag.
8225 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
8227 Fix cases when the varsions of Autoconf and Autotest don't match.
8228 Reported by Noah Misch.
8229 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
8230 at_top_builddir, for compatibility with older autotest.
8231 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
8232 is not set, use at_top_builddir, for compatibility with older
8233 versions of autoconf.
8235 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
8237 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
8238 Problem reported by Patrick Welche.
8240 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
8242 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
8243 sed substitution command, so that we allow | in program prefixes
8244 and program suffixes. (& is a problem anyway; we're not fixing
8245 that here.)
8246 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
8247 configure_input, top_builddir, srcdir, etc.
8248 * lib/autotest/general.m4 (AT_INIT): Likewise, for
8249 PATH_SEPARATOR in AUTOTEST_PATH.
8251 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
8253 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
8254 for loop over config.site files using `set', to allow
8255 directory names containing IFS characters.
8257 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
8259 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
8260 directories with weird names. Apparently some people like living
8261 on the edge. However, improve the test that "pwd" actually does
8262 report a name for the working directory.
8263 * NEWS: Remove the claim that we test for funny chars in dir names.
8265 2005-07-01 Stepan Kasal <kasal@ucw.cz>
8267 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
8268 replaced ...

8277 about #include <config.h>.
8278 (Generic Functions): Mention the Gnulib project.
8279 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
8281 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
8282 document to output the default config_* lists to config.status.
8283 Don't recognize option --file, if the functionality is not there.
8284 Likewise for --header; moreover, recognize --he and --h as shortcuts
8285 for --help in that case.
8287 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
8288 matches the order of execution. No code changed.
8290 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8292 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
8293 single-quoted -cmdline argument in Portland Group compiler.
8294 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
8296 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>

8303 descriptors to child processes; reported by Norman Gray.
8305 2005-06-29 Stepan Kasal <kasal@ucw.cz>
8307 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
8309 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
8310 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
8311 (AC_SUBST): Call it.
8312 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
8313 the directory specific variables; but don't call it for configure_input.
8315 2005-06-28 Derek Price <derek@ximbiot.com>
8317 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
8318 addition.
8320 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
8322 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
8323 directory have inherent problems with special characters like spaces,
8324 due to limitations in Make syntax. Problem reported by Alexandre
8325 Duret-Lutz.
8326 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
8327 Also, fix Tru64 porting problem with shell patterns,

8339 from Justace Clutter.
8340 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
8341 variable into diagnostic. Make the diagnostic an error, not a warning,
8342 because we really don't support spaces and suchlike in dir names.
8343 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
8344 Don't worry about backslashes in srcdir; it can't happen now.
8345 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
8346 Simplify ac_optarg handling.
8347 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

8355 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
8357 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
8358 that '\|' is not allowed in BREs; recommend using newline separated
8359 list of patterns instead of multiple -e options.
8361 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
8363 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

8369 2005-06-21 Stepan Kasal <kasal@ucw.cz>
8371 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
8372 b, t, r, w commands require single space, while : cannot have any.
8373 (Special Shell Variables): Fix sed code this in the example.
8374 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
8375 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
8377 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
8378 expand to the empty list. Don't use two pairs of m4_changequote,
8379 it's not necessary.
8381 2005-06-20 Derek Price <derek@ximbiot.com>
8383 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
8385 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
8387 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
8388 * doc/autoconf.texi:
8389 Don't mention Solaris versions so much, if a
8390 problem is common to all extant versions of Solaris. Say "SunOS
8391 4" instead of "SunOS" for SunOS 4.
8392 (awk): Mention more of the limitations of traditional Awk.
8393 (cat): Don't talk about cat -v.
8395 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
8397 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
8398 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
8399 but the implementation is entirely different and is designed
8400 to be compatible with glibc strverscmp.
8401 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
8403 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
8404 on Mac OS X 10.4 reported by Peter O'Gorman in:
8405 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
8406 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
8407 Use shell builtins rather than 'expr', to work around expr bug.
8409 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
8411 * doc/autoconf.texi: "filesystem" -> "file system".
8412 "behaviour" -> "behavior".
8413 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
8414 * lib/autoconf/general.m4: Omit blank after ":" sed command,
8415 as per POSIX.
8416 * lib/m4sugar/m4sh.m4: Likewise.
8417 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
8418 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
8420 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
8421 (.x.1): Ignore the time stamp in the .TH line when deciding whether
8422 to update the man page. That way, we don't have to check in new
8423 man pages every month.
8425 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
8426 quotes and backslashes. Patch from Derek Price.

8431 AS_TR_SH.
8433 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
8435 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
8436 -u, since it outputs chatter if the input files are the same.
8437 Problem reported by Ralf Menzel.
8439 2005-06-08 Derek Price <derek@ximbiot.com>
8441 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
8442 renaming them since they are about to be redefined anyhow.
8444 2005-06-08 Derek Price <derek@ximbiot.com>
8446 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
8447 redefined M4 macros to this node. Document m4_include & m4_sinclude.
8448 Move m4_undefine to alphabetical order.
8450 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
8452 * README: Recommend GNU M4 1.4.3 or later.
8453 * doc/autoconf.texi (Introduction): Likewise.
8454 Reword to avoid some formatting glitches.
8455 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
8456 Clarify explanation of HP compiler bug.
8457 Redo example output tp match current CVS snapshot.
8458 Use @example.org in email addresses when the examples
8459 might get inadvertently cut-and-pasted into user code.
8460 Remove example of autom4te usage that doesn't seem to work now.
8461 Use modern AC_INIT (except when the example is meant to be
8462 shown with Autoconf 2.13).
8463 Update ksh info for Solaris 9 and later.
8464 KB -> kB.
8465 Modernize description of Automake versions a bit.
8466 Don't claim a future version of Autoconf is near.

8469 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8471 * doc/autoconf.texi: Add [] to examples, so that the manual
8472 follows its own advice about quoting better.
8473 Reword to avoid some formatting glitches.
8474 * doc/installt.exi: Reword to avoid some formatting glitches.
8476 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
8477 Tru64 ksh pattern matching bug. Reported against Libtool by
8478 Albert Chin <libtool@mlists.thewrittenword.com> and
8479 Nicolas Joly <njoly@pasteur.fr>.
8481 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8483 m4_cdr of one-member list was [[]] (one-member list containing an
8484 empty string) instead of [] (an empty list. Callers were skewed to
8485 match this misbehaviour. As a consequence of this:
8486 - m4_foreach([x], [], [foo]) expanded to `foo', while
8487 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
8488 This bug has been fixed:
8490 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
8491 expand to an empty string; print error msg if called without
8492 an argument list.
8493 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
8494 misbehaviour; handle [] and [[]] correctly.
8496 2005-06-06 Stepan Kasal <kasal@ucw.cz>
8498 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

8500 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
8502 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
8504 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
8505 swallow records with more than 99 fields.
8506 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
8507 parse the long line.
8509 2005-06-04 Stepan Kasal <kasal@ucw.cz>
8511 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
8512 swallow literals longer than 399. Reported by Ralf Wildenhues.
8513 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
8514 to workaround this limitation.
8516 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
8518 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
8519 to gfortran, and make these the first two compiler names
8520 checked (following the general autoconf preference for gcc).
8522 2005-06-03 Stepan Kasal <kasal@ucw.cz>
8524 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
8525 (DISTCLEANFILES): Remove $(check_SCRIPTS).
8526 (testsuite): Make sure autotest.m4f is up-to-date before using it.
8528 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
8530 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
8531 expression of unbounded size when processing the --list
8532 option. This runs afoul of a limit of 399 bytes per regular
8533 expression on AIX. Problem reported by Ralf Wildenhues.
8535 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
8537 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
8538 * doc/autoconf.texi (Particular Headers): Reword example
8539 for multiline stdbool replacement.
8540 (Setting Output Variables): Reword text a bit. Don't
8541 give all the details about |#_!!_#|.
8542 Reword description of line replacement.
8544 2005-05-31 Dan Manthey <dan_manthey@partech.com>
8546 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
8547 now contain newlines, and substituted files must be referenced on
8548 a line alone; the sed scripts to substitute them are now very
8549 different.
8550 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
8551 commands can be put in a sed script portably.
8552 * doc/autoconf.texi (Setting Output Variables): Document above
8553 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
8554 use of multiline substitution.

8564 * tests/local.at: Don't attempt to check for negated character
8565 classes in shell scripts. The test was too brittle.
8567 2005-05-25 Stepan Kasal <kasal@ucw.cz>
8569 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
8570 * doc/autoconf.texi (Limitations of Builtins): Document this
8571 limitation.
8573 2005-05-24 Stepan Kasal <kasal@ucw.cz>
8575 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
8576 common code; used in many places in the tree.

8583 messages when ac_unique_file is not found.
8584 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
8585 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
8586 commands, for consistency with AC_MSG_ERROR and such.
8588 * bin/autoconf.as: Make more use of "shift 2" in option processing.

8598 2005-05-20 Stepan Kasal <kasal@ucw.cz>
8600 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
8601 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
8602 (ac_top_builddir): ... this ...
8603 (ac_top_build_prefix): ... to this; the old name is also kept, for
8604 backward compatibility.
8605 (ac_top_builddir_sub): New variable, without the trailing slash,
8606 always nonempty.
8607 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
8608 * doc/autoconf.texi (Configuration Actions): Rename
8609 ac_top_builddir to ac_top_build_prefix.
8610 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
8611 at_top_builddir to at_top_build_prefix.

8619 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8621 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
8622 argument to m4_foreach. I guess it was necessary in the past,
8623 but I think it's a no-op now.
8625 2005-05-17 Stepan Kasal <kasal@ucw.cz>
8627 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
8628 ``cat <<_ACEOF'' commands to one.
8629 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
8630 * lib/autoconf/status.m4: On various places, use expr instead of
8631 ``echo|sed.''
8632 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
8633 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
8634 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
8635 a range.
8636 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
8637 the wrong patterns between ``case'' and ``esac.'' The previous
8638 code had false positives.
8640 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
8642 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
8643 as on 2005-05-02.
8644 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

8707 quoting rules. Problems noted by Stepan Kasal.
8708 Also, throughout this document, be more careful about white space.
8709 "blank", "white space", and "space" all have different meanings
8710 and we should be careful to say what we mean.

8761 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
8762 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
8763 comment and reduce m4_default([foo], []) to [foo].
8764 (m4_strip): Update the explanation.
8766 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
8768 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
8769 Remove core.conftest.* too; it's generated by Tru64 5.1.
8770 Problem reported by Jennis Pruett.
8771 * lib/autoconf/functions.m4
8772 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8773 Don't bother to remove core files; AC_RUN_IFELSE should do that
8774 for you.
8776 2005-04-19 Stepan Kasal <kasal@ucw.cz>
8778 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

8795 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8797 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
8798 as well as configure.in. Problem reported by Gregorio Guidi.
8800 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
8802 * doc/autoconf.texi (Particular Functions): Use gnulib's current

8813 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
8815 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
8816 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
8818 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8820 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
8821 Merge `-z option' as well for the benefit of Solaris link flags. Pass
8822 whole-archive (-zallextract, -zdefaultextract) options in the hope of
8823 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
8824 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
8826 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
8828 * NEWS: The configure command now warns you if you attempt to use
8829 a directory whose name contains a special character like space,
8830 newline, or "\".
8831 * doc/autoconf.texi (Installation Directory Variables): Allow
8832 "," in file names. Do not use \@; it's not a portable regexp.
8833 * bin/Makefile.am (edit): Likewise.
8834 * lib/Makefile.am (edit): Likewise.
8835 * tests/Makefile.am (edit): Likewise.
8836 * tests/semantics.at: Likewise.

8840 * doc/autoconf.texi (File System Conventions): Warn about
8841 unportable file names.
8842 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
8843 (AC_INIT): Use it.
8844 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
8845 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
8846 ac_pwd, and quote srcdir.
8847 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
8849 * doc/autoconf.texi: Fix some systematic formatting problems.
8850 ".)" needs a following @: if not at the end of a sentence, and
8851 similarly for "!)". "etc." should be preceded by a comma.
8852 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
8854 2005-03-22 Bruno Haible <bruno@clisp.org>
8856 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
8857 argument is often called 'build-aux'.
8859 2005-03-07 Stepan Kasal <kasal@ucw.cz>
8861 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
8862 macro AC_TRY_LINK is obsolete.
8863 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
8864 `AC_CONFIG_FILES'.
8866 2005-02-24 Stepan Kasal <kasal@ucw.cz>
8868 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
8869 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
8870 from a Common Lisp's `cl'.
8871 (AC_PROG_CXX): Behave according to the documentation: don't
8872 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
8873 make the variable CCC precious; use `cl.exe', not `cl'.
8875 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8876 Alexandre Duret-Lutz <adl@gnu.org>
8878 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
8879 /dev/null, as "configure" shouldn't read stdin, and this insulates
8880 us from problems (e.g., when testing for "cl"). Also, do this
8881 redirection before invoking "hostname" or "uname", and keep the
8882 original input stream available via...
8883 (AS_ORIGINAL_STDIN_FD): ... this new macro.
8884 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
8885 bother with "</dev/null" since it's now done at the top of
8886 'configure'.
8887 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8888 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

8894 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8896 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8897 newline if neither \c nor -n work, as that would output two
8898 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8900 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8902 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8903 This causes that any required macros inside will get before the if.
8904 * doc/autoconf.texi (autom4te.cache): A typo.
8906 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8908 Undo previous change, except keep the change to
8909 lib/autoconf/programs.m4 that replaced grep with shell
8910 pattern-matching. This is because net-snmp configure reads stdin.
8911 Reported by Noah Misch.
8913 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8915 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8916 from /dev/null, as "configure" shouldn't read stdin, and this
8917 insulates us from problems (e.g., when testing for "cl").
8918 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8919 before invoking "hostname" or "uname".
8920 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8921 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8922 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8923 "</dev/null" since it's now done at the top of 'configure'.
8924 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8925 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8926 Also, replace grep with shell pattern-matching, to save a process.
8928 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8930 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8931 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8932 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8933 compiler.
8935 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8937 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8938 grep -q isn't portable. Improve grep -s explanation.
8939 Problem reported by Dan Manthey.
8941 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8943 * doc/autoconf.texi (Special Shell Variables): Clarify
8944 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8946 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8948 * doc/autoconf.texi: Use @acronym for DJGPP.
8949 Fix some @code's that should have been @env's, and vice versa.
8950 Sort environment variable names.
8951 Mention that shells no longer inherit IFS.
8952 Don't recommend PATH_SEPARATOR=';' so strongly.
8953 Mention that $RANDOM might expand to the empty string.
8954 "symlink" and "soft link" -> "symbolic link".
8955 Improve mktemp description (reported by Bruno Haible).
8957 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8959 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8960 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8961 Likewise.

8965 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8967 * NEWS: Mention AT_COPYRIGHT.
8969 * tests/local.at (AT_CMP): Use diff directly on input files rather
8970 than copying them.
8972 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8973 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8975 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8976 and Paul Eggert <eggert@cs.ucla.edu>

8986 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8987 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8988 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8989 (Standard regular expressions): New test.

8991 excess test name quoting.
8992 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8993 CPPFLAGS to `configure' instead of setting it in `configure'.
8995 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8996 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8997 on some platforms.
8999 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
9000 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

9028 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
9030 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
9031 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
9033 Try not to generated lines of unlimited length, as POSIX places a
9034 2047-byte limit on line length of portable text files.
9035 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
9036 Use newline as a separator, not space.

9045 are restored after function return.
9047 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
9049 * doc/autoconf.texi (Special Shell Variables): Mention _,
9050 BIN_SH, DUALCASE. Say that variables other than "status" are safe
9051 if they contain a lower-case letter. The DUALCASE problem was
9052 reported by Ralf Wildenhues.
9054 * bin/autoconf.as: Don't exit with status 0 after write failure
9055 with --help or --version.

9062 Unicos 9 sed limitations.
9063 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

9067 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
9069 * man/Makefile.am (.x.1): Go back to the simple solution, but take
9070 care to echo the commands, so the user knows what's going on.
9071 Modified from a suggestion by Stepan Kasal.
9073 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

9092 2005-01-29 Stepan Kasal <kasal@ucw.cz>
9094 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
9095 Update the long comment explaining it.
9097 m4_require no longer writes an ``is required by'' line to the
9098 execution stack. It contains only one bit of non-redundant
9099 information: that the macro was required, not called. And even
9100 this bit is useless in most situations: have you ever met a macro
9101 which both calls and requires the same macro?
9103 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
9104 (_m4_defun_pro_outer): ... only via this macro, for the outermost
9105 macro.
9106 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
9107 (m4_expansion_stack_pop): Remove the misplaced comment.
9108 (m4_require): Don't put the ``is required by'' line to the
9109 execution stack; slightly improve the out-of-a-defun error message.
9110 (_m4_divert_grow): New macro, counter for the temporary diversions.
9111 (_m4_require_call): Use it.
9112 * tests/m4sugar.at (m4_require): Expect output without the
9113 ``is required by'' messages.
9115 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
9117 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
9118 rather than x for expr.
9120 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
9121 this is safe.
9122 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

9134 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
9135 from masters, so that FileUtils.pm's update_file provide --force
9136 support.
9137 * bin/autoheader.in: Pass $force to update_file so that
9138 config.h.in is always recreated when --force.

9142 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
9144 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
9146 * doc/autoconf.texi (Limitations of Builtins): Clarify that
9147 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
9149 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
9151 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
9152 Warn about newline stripping in `` and $(). Update Solaris
9153 version to 9.
9154 (Limitations of Builtins): Use expr "X...", not expr "x...", as
9155 X insulates us from future changes to Posix.
9156 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
9157 stripping.
9159 2005-01-19 Stepan Kasal <kasal@ucw.cz>

9177 ulongval to be static, to avoid unwanted GCC warning. Problem
9178 reported by Michael Jennings via Daniel Reed; see
9179 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
9181 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
9183 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

9188 new variables.
9190 2005-01-04 Noah Misch <noah@cs.caltech.edu>

9193 not seem to work, assume it does set $(MAKE).
9194 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
9196 2005-01-03 Stepan Kasal <kasal@ucw.cz>
9198 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

9204 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
9205 (_m4_divert_n_stack): New macro; the expansion is
9206 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
9207 otherwise.

9523 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
9524 "char c = '\200';" rather than "char c = 0x80;" as the

9674 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
9675 texinfo.tex for now (done by hand now).
9676 * Makefile.maint (wget_files, cvs_files):
9677 Remove ansi2knr.c; nobody uses it.
9678 (ansi2knr.c-url_prefix): Remove.
9679 (cvs-update): Fix test for failure. I don't know why it ever
9680 worked...
9682 * doc/autoconf.texi: Update URLs, some of which went stale.
9683 Use @uref rather than @href.
9685 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
9686 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
9688 * config/config.guess, config/config.sub, config/elisp-comp,
9689 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
9690 doc/fdl.texi, doc/standards.texi: Sync with master copy.
9692 * NEWS, TODO, configure.ac, bin/autoscan.in,
9693 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,

9700 Use "file name" rather than "filename" or "path",
9701 to be consistent with the terminology of the GNU coding standards.
9703 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
9705 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
9706 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
9707 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
9708 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
9710 More fixes to support spaces in the name of the build directory.
9711 This isn't a complete fix but it's an improvement.
9713 * bin/autoconf.as (autom4te_options): New var.
9714 Use it instead of appending to AUTOM4TE, so that we can allow
9715 spaces in the build directory's absolute name.
9716 * bin/autoheader.in ($autoconf): Allow spaces in file names.
9717 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
9718 AT_CHECK_NOESCAPE): Likewise.
9719 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
9720 main program): Likewise.
9722 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
9724 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

9728 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
9730 * doc/autoconf.texi (Function Portability): Document isinf and
9731 and isnan. From a suggestion by Kevin Ryde.
9733 * lib/Autom4te/General.pm (END): Return correct exit status even
9734 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
9736 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
9738 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
9739 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
9740 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
9742 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
9744 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
9745 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
9746 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
9747 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
9748 * lib/autom4te.in (Automake-preselections): Preselect
9749 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
9751 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
9753 * lib/autom4te.in (Automake-preselections): Preselect
9754 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
9755 trace them.
9757 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
9759 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
9760 Tru64.
9761 * doc/autoconf.texi (Shellology): Mention BIN_SH.
9762 Document problem with "`""`" in pdksh POSIX mode.
9764 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
9766 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
9767 with pdksh, too. Problem reported by Patrick Welche via
9768 Gary V. Vaughan.
9769 * doc/autoconf.texi (Shellology): Note that set -o posix is
9770 useful for pkdsh, too.
9772 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
9774 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
9775 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
9776 Don't fail if ENV or BASH_ENV is readonly.
9777 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
9778 etc. are read only. Problem reported by Ludovic Courtes.
9780 2004-06-23 Noah Misch <noah@cs.caltech.edu>
9782 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
9783 zsh, disable GLOB_SUBST to avoid backslash handling problems.
9784 (trivial change)
9786 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
9788 * doc/autoconf.texi (File System Conventions): Warn about
9789 names like "aux". Problem reported by Eric Blake.
9791 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
9792 by zero instead of array size, so that we can use any arithmetic
9793 constant expression (instead of requiring an integer constant
9794 expression). This allows us to test expressions like DBL_MAX <
9795 LDBL_MAX, which didn't conform to the C standard using the old
9796 method.
9797 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
9798 now that we can do floating-point tests at compile time.
9800 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
9802 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
9803 and LDBL_EPSILON, as the resulting expression isn't an
9804 integer constant expression and violates the C standard.
9805 Problem reported by Nelson H. F. Beebe. Also, check
9806 for "L" suffix, and check that long double doesn't have
9807 worse range or precision than double, that mixed-mode
9808 arithmetic doesn't generate a diagnostic, that double
9809 constants fit in long double.
9811 2004-06-03 Kevin Ryde <user42@zip.com.au>
9813 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
9814 malloc(0) and realloc(NULL,size).
9816 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
9817 Bob Proulx.
9819 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
9821 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
9822 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
9823 by Jim Meyering.
9825 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9827 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
9828 can be rewritten using if-then-else. Suggested by Bruno Haible.
9830 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9832 * doc/autoconf.texi (testsuite Scripts): Fix typo.
9833 Problem reported by Stepan Kasal.
9835 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9837 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
9838 change). Patch reported by Ralf Wildenhues in
9839 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
9841 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
9842 function F exists if the compiler and linker let you compile an
9843 expression like (F != 0). Recent versions of GCC optimize away
9844 the reference to F in that case, since every function address must
9845 be nonzero, so the link succeeds even if F does not exist.
9846 Problem reported by Manu in
9847 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
9849 * doc/autoconf.texi (Systemology): Standardize on the spelling of
9850 "Unix". Many uses changed.
9851 (Limitations of Builtins): Explain better why the ! command isn't
9852 portable.
9854 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
9856 * lib/autom4te.in (Automake-preselections): Preselect
9857 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
9859 2004-05-19 Kevin Ryde <user42@zip.com.au>
9861 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
9862 referencing AC_FUNC_STRERROR_R.
9864 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
9865 note pessimistic assumption when cross compiling.
9867 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
9869 * doc/autoconf.texi (Limitations of Make): Note that BSD make
9870 (until 2004) invoked subcommands with sh -e, contra POSIX.
9871 Reported by Kevin Ryde.
9873 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
9875 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
9876 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
9877 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
9878 `test -f " /usr/bin/grep"', which _always_ failed.
9879 (AC_PROG_SED): Ditto bogus PATH fix.
9880 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
9881 requires that grep correctly supports _multiple_ `-e' options, rather
9882 than stating only that grep should accept `-e'.
9884 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9886 Port to C99, which requires that 'exit' be declared.
9888 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9889 to ensure that stdlib.h is included.
9890 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9891 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9892 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9893 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9894 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9895 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9896 when using 'exit' in a test; C99 requires that 'exit' be declared.
9898 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9900 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9901 now prefers 'grep' implementations that accept -e.
9902 (Limitations of Usual Tools): Describe problems of traditional
9903 egrep and fgrep with long input lines, and of traditional grep
9904 with -e.
9905 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9906 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9907 All callers changed. Append /usr/xpg4/bin to the PATH, for
9908 Solaris.
9909 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9910 the user with complaints about multiple -e options.
9911 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9912 Define it with AC_PROG_GREP.
9913 * configure.ac (AC_PROG_GREP): Add.
9914 * lib/freeze.mk (GREP): New macro.
9916 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9918 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9919 a possible candidate only after all others fail, rather than
9920 consulting it first. This improves backward compatibility by
9921 better reflecting the way shell selection occurred in previous
9922 versions of Autoconf, and should help to avoid triggering latent
9923 problems in other packages, such as the one in Automake where zsh
9924 is not handled robustly:
9925 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9926 Although it is not Autoconf's responsibility to work around
9927 problems in Automake, it nevertheless makes sense to avoid
9928 introducing unnecessary incompatibilites.
9930 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9931 Gary V. Vaughan <gary@gnu.org>
9933 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9934 how deeply nested we are when a suitable tool is found, set the
9935 ac_path_TOOL_found flag.
9936 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9937 nested we are in this macro. Break out of all 3 nested loops if
9938 ac_path_TOOL_found is set.
9940 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9942 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9943 of the _AS_PATH_WALK loop too if GNU flavor is found.
9945 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9947 * doc/autoconf.texi (Limitations of Make): Update documentation
9948 for `$<'. New entry `Long lines', based on a report from Simon
9949 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9950 paragraph about DJGPP, based on a mail from Richard Dawe.
9952 2004-04-20 Paul Eggert <eggert@twinsun.com>
9954 * tests/c.at (C keywords): Don't assume that GCC supports
9955 "restrict" and "inline", as sufficiently-old GCC versions do not
9956 (also, GCC configured to be in pedantic C89 mode does not).
9957 Problem reported by Sumit Pandya in:
9958 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9960 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9961 consider -g to work if it generates warnings when plain compiles
9962 don't. Problem reported by Braden McDaniel in:
9963 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9965 * doc/autoconf.texi (Slashes): New section, to document a problem
9966 reported by Jim Meyering in:
9967 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9969 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9970 linker output files before linking, to work around IRIX 6 linker bug.
9971 Problem reported by Rainer Orth in:
9972 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9974 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9976 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9977 best tool so far counter rely on the tool path variable name to
9978 avoid checks for one tool being affected by the results of running
9979 the length check on a previous tool.
9981 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9982 match expression argument, as different greps have different
9983 regular expression flavours.
9984 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9985 literals.
9986 (AC_PROG_EGREP): Pass 'EGREP$'.
9987 (AC_PROG_GREP): Pass 'GREP$'.
9989 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9991 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9992 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9994 2004-03-29 Paul Eggert <eggert@twinsun.com>
9996 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9997 Types, Specific Compiler Characteristics, System Services,
9998 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9999 etc. consistently instead of 'long', 'short', 'unsigned' etc.
10000 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
10001 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
10002 Likewise.
10003 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
10004 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
10005 AC_TYPE_OFF_T): Likewise.
10006 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
10007 Likewise.
10009 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
10010 pacify libtool 1.5.2. Fix quoting problems in sed command.
10012 2004-03-28 Paul Eggert <eggert@twinsun.com>
10014 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
10015 now defines HAVE_DECL_TZNAME if it is declared, when
10016 HAVE_STRUCT_TM_TM_ZONE is not defined.
10017 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
10018 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
10019 for HAVE_TZNAME.
10021 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
10023 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
10024 superfluous backslashing of quotes (") in sed expressions;
10025 thanks to Paul Eggert.
10027 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
10029 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
10030 Fortran compiler is ifort, also added pghpf; thanks to Nelson
10031 H. F. Beebe for the bug report.
10033 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
10035 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
10036 quoted -cmdline argument in Portland Group compiler (bug
10037 reported by Jeffrey J. Barteet).
10039 2004-03-25 Kevin Ryde <user42@zip.com.au>
10041 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
10042 (Run Time): ... here, where it's now mentioned.
10044 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
10046 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
10047 inherits from language Autoconf-without-aclocal-m4.
10048 (Customizing autom4te): Adjust example; the cache must now be
10049 disabled for language Autoconf-without-aclocal-m4.
10051 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
10052 Nathanael Nerode <neroden@twcny.rr.com>
10054 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
10055 AC_CHECK_TOOLS): Warn if a cross-tool is found without
10056 a prefix.
10057 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
10058 AC_CHECK_TARGET_TOOLS): New macros.
10059 * doc/autoconf.texi (Generic Programs): Document
10060 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
10061 AC_CHECK_TARGET_TOOLS, and warn for future changes
10062 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
10063 AC_CHECK_TOOLS.
10064 (Specifying Names): Document the reason for these future
10065 behavioral changes.
10066 * tests/mktests.sh: Do not generate tests for the
10067 new macros.
10068 * NEWS: Document these changes.
10070 * doc/autoconf.texi: Avoid macros with unbraced arguments,
10071 they make TeX hang up.
10073 2004-03-15 Paul Eggert <eggert@bogus.example.com>
10075 * NEWS: New macro AC_CHECK_ALIGNOF.
10076 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
10077 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
10078 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
10079 vowel.
10080 (AC_CHECK_ALIGNOF): New macro.
10081 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
10082 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
10083 those for sizeof.
10085 2004-03-03 Paul Eggert <eggert@twinsun.com>
10087 * bin/Makefile.am (edit): Don't use $< in a context where
10088 POSIX doesn't require support for it. Use $@.in instead.
10089 Problem reported by Anthony N. Frasso in
10090 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
10091 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
10093 2004-02-23 Gary V. Vaughan <gary@gnu.org>
10095 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
10096 from the next generation of Libtool.

10102 is not always thread-safe. Report from Nathanael Nerode.
10104 2004-02-18 Paul Eggert <eggert@twinsun.com>
10106 Fix a dependencies problem, stemming from a Autoconf 2.59 build
10107 problem on QNX reported by Stephen Rasku in
10108 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
10110 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
10111 $(m4sh_m4f_dependencies); this removes a FIXME.
10112 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
10113 (MAINTAINERCLEANFILES): Split into pieces,
10114 one per related section. Add $(srcdir)/wrapper.in.
10116 2004-02-09 Paul Eggert <eggert@twinsun.com>
10118 * doc/autoconf.texi (Setting Output Variables): Emphasize that
10119 AC_SUBST provides no portable way to escape literal newlines.
10121 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
10122 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
10123 Darwin uses -lcrt2.o and there's little point to cataloging all
10124 the system variants. Partial fix reported by Andreas Waechter in:
10125 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
10126 for bug reported by Nelson H. F. Beebe in:

10129 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
10131 * doc/autoconf.texi (AU_DEFUN): Fix English,
10132 suggested by Paul Eggert.
10133 * lib/autoconf/autoupdate.m4: Correct reference to
10134 acobsolete.m4, suggested by Alexandre Duret-Lutz.
10136 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
10138 * bin/autoupdate.in: Define __file__ so that warnings
10139 refer to the correct file.
10140 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
10141 the behavior of the third argument.
10142 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
10143 correctly the behavior of the third argument. Document
10144 what the three macros that AU_DEFUN defines do. Fix
10145 warning message when the third argument includes $0
10146 (reported by Alexandre Duret-Lutz).
10148 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10149 Eric Sunshine <sunshine@sunshineco.com>
10150 Paul Eggert <eggert@twinsun.com>
10152 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

10154 parameter. Expand _AS_SHELL_FN_SPY.
10155 (AS_INIT_WITH_SHELL_FN): Removed.
10156 (_AS_SHELL_FN_SPY): New macro.
10157 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
10158 macros.
10159 (AS_SHELL_SANITIZE): Remove loop to find better shell
10160 and documentation for the parameter.
10161 (_AS_DETECT_BETTER_SHELL): Move it here.
10162 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
10163 (_AS_RUN): Move it here, support testing with eval.
10164 (AS_REQUIRE_SHELL_FN): Require shell functions when
10165 it is used.
10166 (_AS_LINENO_WORKS): Put around braces, we do not
10167 trigger the bash bug anymore.
10168 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
10169 use AS_INIT_WITH_SHELL_FN.
10170 * bin/autoconf.in, tests/wrapper.in: Regenerated.
10172 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
10174 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
10175 * doc/autoconf.texi: Don't say that the third parameter
10176 is broken.
10177 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
10178 (AU_DEFUN): Honor the third parameter, create autoupdate
10179 macros with AU_DEFINE.
10180 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
10181 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
10182 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
10183 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
10184 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
10185 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
10186 AC_XENIX_DIR): Likewise.
10187 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
10188 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
10189 * lib/autoconf/status.m4: Remove FIXME.
10190 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
10191 that the macro is not present anymore in the updated
10192 configure.ac.
10193 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
10194 of autoupdate.
10196 2004-01-28 Paul Eggert <eggert@twinsun.com>
10198 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
10199 copyright years.
10200 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
10201 2003 (except 1997) to the list of copyright years. This undoes
10202 the 2003-05-22 change, which removed the older years from the list.
10203 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
10205 2004-01-27 Gary V. Vaughan <gary@gnu.org>
10206 Albert Chin-A-Young <china@thewrittenword.com>
10208 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
10209 grep or ggrep program in PATH that accepts as long lines as
10210 possible.
10211 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
10212 AC_PROG_GREP.
10213 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
10214 egrep and fgrep respectively if $GREP -E/-F don't work.
10215 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
10216 _AC_PROG_GREP, and AC_PROG_SED.
10217 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
10218 longest input length accepted by a command.
10219 (AC_PROG_SED): Use it.
10220 * doc/autoconf.texi (Particular Programs): Document the changes.
10221 * NEWS: Updated.
10223 2004-01-27 Paul Eggert <eggert@twinsun.com>
10225 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
10226 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10227 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
10228 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
10230 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
10231 bin/autoconf.in, config/Makefile.in, config/config.guess,
10232 config/config.sub, config/install-sh, config/mdate-sh,
10233 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,

10243 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
10244 tests/actypes.at: Regenerate and/or sync with original
10245 sources.
10247 2004-01-26 Paul Eggert <eggert@twinsun.com>
10249 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
10250 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
10251 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
10252 not <inttypes.h>. Problem reported by Tim Mooney in
10253 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
10254 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
10255 Likewise.
10257 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
10258 otherwise "make check" fails because it forbids cmp (I guess
10259 because cmp treats files as binary on DOS-like systems).
10261 * tests/mktests.sh: Update copyright date to 2004, since some tests
10262 have changed in 2004.
10264 2004-01-23 Gary V. Vaughan <gary@gnu.org>
10266 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
10267 non-truncating sed or gsed program in PATH.
10268 * tests/acprograms.at: Add it.
10269 * doc/autoconf.texi (Particular Programs): Document it.
10270 * NEWS: Updated.
10272 2004-01-15 Paul Eggert <eggert@twinsun.com>
10274 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
10275 -std1 disables some useful extensions on Tru64. Problem reported
10276 by N. Lichtmaier in
10277 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
10279 2004-01-14 Paul Eggert <eggert@twinsun.com>
10281 * doc/autoconf.texi (Programming in M4sh): Document that
10282 AS_MKDIR_P succeeds if the destination is a symbolic link
10283 to an existing directory.
10284 (Limitations of Usual Tools): Note that mkdir -p might not
10285 succeed on symlinks to directories.
10287 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
10289 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
10290 * bin/autoheader.in: Grammar fix in message.
10291 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
10292 Test for dir before calling mkdir -p. (trivial changes)
10294 2004-01-13 Eric Blake <ebb9@byu.net>
10296 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
10297 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
10299 2004-01-10 Jim Meyering <jim@meyering.net>
10301 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
10303 2004-01-09 Paul Eggert <eggert@twinsun.com>
10305 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
10306 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
10307 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
10308 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
10309 AC_COMPILE_IFELSE, since we now assume our caller invokes
10310 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
10311 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
10312 of AC_RUN_IFELSE; this avoids the warning mentioned above.
10313 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
10315 2004-01-07 Paul Eggert <eggert@twinsun.com>
10317 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
10318 `"'...'"`, as it's confusing (and I suspect it may not work on
10319 some platforms). The code was incorrect anyway, as it assumed
10320 that \$ evaluated to itself in that context. Reported by
10321 Alexandre Duret-Lutz.
10323 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
10325 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
10326 and _LT_AC_TAGCONFIG.
10328 2004-01-06 Paul Eggert <eggert@twinsun.com>
10330 * doc/autoconf.texi (One Macro Call): Fix an incorrect
10331 example, and add more examples. Reported by Eric Sunshine.
10333 2004-01-05 Paul Eggert <eggert@twinsun.com>
10335 * doc/autoconf.texi (Limitations of Usual Tools):
10336 Remove warning against "rm -fr" introduced yesterday; it
10337 was a false alarm.
10339 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
10340 autoscan, autoupdate, ifnames): Don't use chmod -w.
10341 * lib/Makefile.am (autom4te.cfg): Likewise.
10342 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
10343 "chmod -w".
10345 2004-01-04 Paul Eggert <eggert@twinsun.com>
10346 Paolo Bonzini <bonzini@gnu.org>
10348 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
10349 by doing lineno substitution only on lines containing "$LINENO".
10351 2004-01-04 Paul Eggert <eggert@twinsun.com>
10353 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
10354 Use "rm -f" to remove conftest.sed, not plain "rm".
10355 Bug reported by David Relson in
10356 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
10358 * Makefile.am (autom4te-update):
10359 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
10360 * Makefile.maint (my-distcheck, do-po-update): Likewise.
10361 * doc/autoconf.texi (Guidelines): Likewise.
10362 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
10363 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.
10364 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10365 * lib/autotest/general.m4 (AT_INIT): Likewise.
10366 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
10367 * tests/Makefile.am (clean-local): Likewise.
10368 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
10369 srcdir): Likewise.
10370 * doc/autoconf.texi (Limitations of Usual Tools):
10371 Warn against "rm -fr".
10373 2004-01-03 Paul Eggert <eggert@twinsun.com>
10375 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
10376 -c -o might not work. From a suggestion by Kevin Ryde.
10377 (C Compiler, Generating Sources, Limitations
10378 of Usual Tools, Limitations of Make, Making testsuite Scripts):
10379 Don't put '-o' after non-options, as POSIX doesn't allow this.
10380 Mention that cc's name might be gcc or c89 or whatever.
10382 2004-01-04 Kevin Ryde <user42@zip.com.au>
10384 * doc/autoconf.texi: Add various further index entries.
10386 2003-12-29 Paul Eggert <eggert@twinsun.com>
10388 * bin/autoreconf.in (autoreconf_current_directory):
10389 Fix typo: mkdir without umask arg.
10391 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
10393 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
10394 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
10395 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
10396 explanation clearer.
10398 2003-12-24 Andreas Schwab <schwab@suse.de>
10400 * doc/autoconf.texi (Default Includes): Fix misspelling of
10401 AC_INCLUDES_DEFAULT.
10403 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10405 * configure.ac: Test if sh -n works.
10406 * configure: Regenerate.
10407 * tests/atlocal.in: Store the result here.
10408 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
10409 tools.at, looking in atlocal's ac_cv_sh_n_works instead
10410 of explicitly testing.
10411 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
10412 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
10413 * tests/tools.at (Syntax of the shell scripts): Simplify
10414 using AT_CHECK_SHELL_SYNTAX.
10415 (Syntax of the Perl scripts): Remove definition of
10416 AT_CHECK_PERL_SYNTAX.
10418 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
10420 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
10421 stderr to /dev/null.

10427 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
10428 Extracted from AS_SHELL_SANITIZE.
10429 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
10430 macros.
10431 (AS_SHELL_SANITIZE): Move reinvocation code from
10432 _AS_LINENO_WORKS, use it to find out if shell
10433 functions work.
10434 (_AS_LINENO_WORKS): Don't find another shell if $LINENO

10447 * config/announce-gen (&print_locations, &print_signatures)
10448 (&sizes): New.
10449 Use them.
10450 No longer rely on Gnus to inline the list of signatures: compute
10451 them on the fly.
10453 2003-11-24 Akim Demaille <akim@epita.fr>
10455 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
10456 override some files.
10457 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
10458 From Debian Autoconf 2.58.
10460 2003-11-24 Akim Demaille <akim@epita.fr>
10462 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote $ac_popdir

10468 * TODO: Remove already done things. Update the part about finding
10469 tools for the target.

10473 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H, AC_DIR_HEADER):
10474 Make wording more consistent.
10475 * lib/autoconf/specific.m4 (AC_CYGWIN, AC_EMXOS2, AC_MINGW32):
10476 Explain the transition better.
10477 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS): Explain
10478 the transition better.
10480 2003-11-24 Paolo Bonzini <bonzini@gnu.org>
10482 * doc/autoconf.texi (Obsoleting Macros): Don't document the third
10483 parameter of AU_DEFUN.
10484 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
10485 (AU_DEFUN): Remove the third parameter, it was not used.
10486 Use AC_DEFUN directly, not AU_DEFINE.
10487 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
10488 the expanded body, consistently with other macros such as AC_USG.
10490 2003-11-17 Paul Eggert <eggert@twinsun.com>
10492 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
10493 into the initial confdefs.h, to work around a bug in NextStep 3.3
10494 patch 3 reported by Eric Sunshine.
10496 2003-11-15 Kevin Ryde <user42@zip.com.au>
10498 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
10499 than $target since the latter is not usual, add guidelines on when to
10500 use or not use the system type.
10502 2003-11-12 Derek Price <derek@ximbiot.com>
10504 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

10515 * configure.ac: Bump to 2.59a.
10516 Require 2.59.
10518 2003-11-06 Akim Demaille <akim@epita.fr>
10520 Version 2.59.
10522 2003-11-05 Alexandre Duret-Lutz <adl@gnu.org>
10524 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
10525 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,
10526 and ac_abs_top_srcdir are absolute paths.
10527 * lib/m4sugar/m4sh.m4 (AS_SET_CATFILE): Remove misleading comment.

10533 2003-11-05 Kevin Ryde <user42@zip.com.au>
10535 * doc/autoconf.texi (Using Autotest): Avoid @strong{Note: ...}, since
10536 it provokes a warning from makeinfo about looking like a cross
10537 reference in info output.

10665 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
10667 2003-10-10 Andreas Schwab <schwab@suse.de>
10669 * bin/autoheader.in: Avoid empty first line in --version and

10681 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
10682 -mGLOB_options_string stuff for Intel ifc, which can cause
10683 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
10684 pattern-matching instead of grep.

10704 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
10706 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
10707 cache variable instead of $G77 to decide whether to include -O2,
10708 since $G77 is specific to Fortran 77.

10717 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
10718 arguments so that it can be used with syntax identical to
10719 AC_PROG_F77, and so that we can more easily decide to
10720 remove/deprecate the DIALECT optional argument in the future if it
10721 proves troublesome.
10722 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
10723 non-freeform-supporting compilers. Document freeform flags.
10725 2003-10-03 Akim Demaille <akim@epita.fr>
10727 * configure.ac: Look for emacs, not macs.
10728 Reported by Eric Sunshine.
10730 2003-10-03 Akim Demaille <akim@epita.fr>
10732 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
10733 * bin/autoreconf.in (autoreconf_current_directory): Create the
10734 AUX_DIR if needed, for sake of automake --add-missing etc.
10735 Suggested by Alexandre Duret-Lutz.
10737 2003-10-03 Akim Demaille <akim@epita.fr>
10739 * configure.ac: Quotation and formatting changes.

10762 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
10764 2003-09-30 Akim Demaille <akim@epita.fr>
10766 * config/announce-gen (&print_news_deltas): Extracted from...
10767 (&print_changelog_deltas): here.

10769 (@news_file): this.
10771 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
10773 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
10774 have been created when invoking the compiler.

10787 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
10788 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
10789 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
10790 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
10792 2003-09-26 Akim Demaille <akim@epita.fr>
10794 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
10795 directory for AC_CONFIG_COMMANDS' first argument exists.
10796 This makes valid the invocation of _AC_SRCPATH that follows.
10797 Reported by Eric Sunshine.
10798 * doc/autoconf.texi (Configuration Commands): Adjust.
10800 2003-09-26 Akim Demaille <akim@epita.fr>
10802 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
10803 Reported by Ralf Corsepius.
10805 2003-09-26 Akim Demaille <akim@epita.fr>
10807 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
10808 arguments.

10810 From Bruno Haible.
10812 2003-09-26 Paul Eggert <eggert@twinsun.com>
10814 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

10819 2003-09-26 Akim Demaille <akim@epita.fr>
10821 The test suite are sometimes assigning timings incorrectly.
10822 Reported by Henk Krus.
10823 Diagnosed by Nicolas Joly.
10825 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
10826 AT_help_all.
10827 Instead of making AT_help a sequence of assignments to grow
10828 $at_help_all, just make AT_help_all be the growing contents of
10829 $at_help_all, and make a single assignment in...
10830 (AT_INIT): here.
10831 (at_times_skip): Flip the meaning and rename as...
10832 (at_times_p): this.
10833 (AT_INIT): When summarizing the test that ran, remove
10834 $at_times_file after use, and check it is present before trying to
10835 use it.
10837 2003-09-25 Akim Demaille <akim@epita.fr>
10839 Version 2.57d.
10841 * bin/Makefile.am (edit): Handle '@configure_input@'.
10842 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
10843 (ifnames): chmod -w.
10844 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
10845 executables, not bin/ executables! Otherwise all the magic needed
10846 to find non installed files is turned off. This caused a failure
10847 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
10848 as found in its environment (sent by tests/autoreconf): pointing
10849 to bin/autom4te that could not find its files.
10850 * tests/mktests.sh: Force the replacement of generated files, for
10851 the sake of "mv" program that are interactive when overwriting a
10852 -w file.
10853 * config/install-sh: Upgrade from CVS Automake.
10855 2003-09-23 Paul Eggert <eggert@twinsun.com>

10858 versus test -L issues.
10860 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
10861 Paul Eggert <eggert@twinsun.com>
10863 Trivial change to support GCC's configuration procedure.
10864 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
10865 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
10866 about inconsistency if the preprocessor is set to give errors for
10867 any warning.
10868 * doc/autoconf.texi (C Compiler Characteristics): Document this.
10870 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

10896 2003-09-10 Akim Demaille <akim@epita.fr>
10898 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10899 willing to edit the output files.
10901 2003-09-10 Akim Demaille <akim@epita.fr>
10903 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10904 and AC_FC_FREEFORM.
10905 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10906 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10908 2003-09-09 Akim Demaille <akim@epita.fr>

10921 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
10922 Improve the accuracy of the wording about obsolescence.
10923 From a suggestion by Ian Lance Taylor in
10924 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10926 2003-09-05 Paul Eggert <eggert@twinsun.com>
10928 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
10929 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
10931 2003-09-04 Akim Demaille <akim@epita.fr>
10933 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10934 AC_FUNC_WAIT3.
10936 2003-09-04 Akim Demaille <akim@epita.fr>
10938 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10939 (freeze): When exiting, use $exit_code.
10940 * lib/autoconf/fortran.m4: Comment changes.
10942 2003-09-04 Akim Demaille <akim@epita.fr>
10944 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10946 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10948 Add support for newer Fortran dialects. The F77 interface is
10949 unchanged, and continues to support Fortran 77. New FC macros
10950 correspond to all the old F77 macros, with output variables FC,
10951 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10952 available dialect, but older dialects can be specified. There are
10953 new macros AC_FC_SRCEXT to set the source extension, and
10954 AC_FC_FREEFORM to accept free-form source files.
10956 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10957 New macros.
10958 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10959 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10960 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),

10973 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10974 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10975 Rewrite in terms of the above.
10976 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10977 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

10981 2003-09-02 Paul Eggert <eggert@twinsun.com>
10983 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10984 Document problems with timestamp resolution that 'make', 'cp -p', and
10985 'touch -r' have.
10987 2003-08-27 Akim Demaille <akim@epita.fr>
10989 * tests/m4sugar.at (cross_warning): Make sure to enable the
10990 output, so that we can track spurious m4sugar output.
10991 * tests/local.at: Require 2.57.
10992 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10993 are defaulted by AT_CHECK anyway.
10994 Use AT_CHECK_AUTOM4TE.
10995 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10996 missing dnl.
10998 2003-08-27 Akim Demaille <akim@epita.fr>
11000 * bin/autoheader.in: Issue the "Using auxiliary..." message only
11001 when -Wobsolete is set.
11002 Set it on by default.
11003 Suggested by Klee Dienes.
11005 2003-08-27 Akim Demaille <akim@epita.fr>
11007 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
11008 documentation.
11009 From Guido Draheim.
11011 2003-08-26 Akim Demaille <akim@epita.fr>
11013 * doc/autoconf.texi (Output): Make clear that one can run code
11014 after AC_OUTPUT.
11016 2003-08-25 Akim Demaille <akim@epita.fr>
11018 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
11019 CVS Bison.
11021 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
11023 * bin/autoreconf.in (parse_args): Do not pass --no-force to
11024 Automake versions prior to 1.8.
11026 2003-08-25 Akim Demaille <akim@epita.fr>
11028 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.
11029 From Ville Karaila.
11031 2003-08-24 Akim Demaille <akim@epita.fr>
11033 * configure.ac: Bump to 2.57c.
11035 2003-08-22 Akim Demaille <akim@epita.fr>
11037 Version 2.57b.
11039 * Makefile.cfg (local-checks-to-skip): New.
11040 * Makefile.maint (local-check): Rename as...
11041 (local-checks-available): this.
11042 (local-check): New.
11044 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
11045 * configure.ac: Require Automake 1.7.6.
11047 2003-08-22 Akim Demaille <akim@epita.fr>
11049 Output stack traces in warnings.
11051 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
11052 Replace the former...
11053 (m4_warn): Pass the call stack to _m4_warn.
11054 * bin/autom4te.in: Adjust to output the call stack.
11055 * tests/m4sugar.at (m4@&t@_warn): Adjust.
11057 2003-08-22 Akim Demaille <akim@epita.fr>
11059 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
11060 * bin/autom4te.in: Adjust.
11062 2003-08-21 Akim Demaille <akim@epita.fr>
11064 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
11065 (&verbose): Remove.
11066 (&getopt): Adjust the note and verb channels, depending upon
11067 --verbose.
11068 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
11069 * bin/autoupdate.in: Adjust.
11070 Use &verb, not &verbose.
11072 2003-08-21 Akim Demaille <akim@epita.fr>
11074 * bin/autoheader.in (&parse_args): Use &parse_warnings and
11075 &parse_WARNINGS.
11076 ($help): Use Autom4te::ChannelDefs::usage.
11077 * bin/autoscan.in: Use Autom4te::ChannelDefs.
11078 * lib/Autom4te/General.pm: Don't export error: you don't own it.
11080 2003-08-21 Akim Demaille <akim@epita.fr>
11082 First stab at preserving warnings between calls to autom4te,
11083 including when the cache is used.
11085 There are still several issues: (i) there are too many runs of m4
11086 (one for include, one for warnings, and some more), (ii) warnings
11087 spreading on several lines are not handled gracefully, (iii) the
11088 code meant to have the call stack display for errors does not work
11089 (its handling should move from m4 to autom4te).
11091 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
11092 Use them.
11093 (@preselect): Add m4_warn.
11094 ($exit_status): Remove, use $exit_code.
11095 ($help): Use Autom4te::ChannelDefs::usage.
11096 (&handle_m4): No longer define the m4_warnings.
11097 At each run, extract and report the warnings.
11098 Always cache the result, including if the exit status is on
11099 failure, since if nothing changes, we should result in the same
11100 failure, hence we can use the cache.
11101 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
11102 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
11103 Remove.
11104 (m4_warn): Redefine as a do-nothing: it is its invocation that
11105 matters, as warnings are now reported via traces.
11106 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
11107 the contents of m4_warn: make it _call_ m4_warn, so that tracing
11108 the latter reveals calls to the former.
11110 Adjust the tests.
11112 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
11114 2003-08-21 Akim Demaille <akim@epita.fr>
11116 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
11117 Use them.
11119 2003-08-21 Akim Demaille <akim@epita.fr>
11121 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
11122 forward order.
11123 * lib/Autom4te/ChannelDefs.pm: Doc typos.
11124 (&parse_warnings): Accept a list of warning requests.
11125 (&usage): Return a string, not a side effect.
11126 (cross): New warning category.
11128 2003-08-21 Akim Demaille <akim@epita.fr>
11130 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
11131 (&require_configure_ac): Accept an optional directory argument.
11132 ($configure_ac): Remove.
11133 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
11134 (&catfile): Remove.
11135 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
11136 * bin/autoscan.in: Adjust.
11138 2003-08-20 Akim Demaille <akim@epita.fr>
11140 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
11141 Reported by Alexandre Duret-Lutz.
11143 2003-08-20 Akim Demaille <akim@epita.fr>
11145 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
11146 * bin/autom4te: Adjust.
11147 In particular, be Autoconf tools are really silent when properly
11148 working, bind the verbosity of the 'note' channel to $verbose.
11149 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
11150 (&xsystem, &contents): Remove, since they are exported by...
11151 * lib/Autom4te/FileUtils.pm: this.
11152 More perldoc.
11153 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
11154 * lib/Autom4te/FileUtils.pm: here.
11156 2003-08-20 Akim Demaille <akim@epita.fr>
11158 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
11159 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
11160 from CVS Automake.
11162 2003-08-20 Akim Demaille <akim@epita.fr>
11164 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
11165 (autom4te-update): New.
11166 * Makefile.cfg (update): Bind autom4te-update.
11168 2003-08-19 Derek Price <derek@ximbiot.com>
11170 * lib/autotest/general.m4: Comment various HELP_* diversions.
11171 (PARSE_ARGS_BEGIN): New section for option parsing related
11172 initialization.
11173 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
11174 package specific options and associated help.
11176 2003-08-19 Akim Demaille <akim@epita.fr>

11180 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
11182 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

11185 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
11186 and m4_sinclude.
11188 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
11190 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
11191 (Autoconf-without-aclocal-m4): ... this new language.
11192 * doc/autoconf.texi (autom4te Invocation): Mention
11193 Autoconf-without-aclocal-m4.
11195 2003-08-18 Derek Price <derek@ximbiot.com>
11197 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
11198 RUN-IF-PASS optional arguments.
11200 2003-08-18 Derek Price <derek@ximbiot.com>

11207 STDOUT & STDERR arguments.
11209 2003-08-14 Derek Price <derek@ximbiot.com>
11211 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
11212 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
11213 shorter column three. Add DESCRIPTION to log file content.
11215 2003-08-13 Derek Price <derek@ximbiot.com>
11217 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
11218 output.
11220 2003-08-12 Derek Price <derek@ximbiot.com>
11222 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
11223 (AT_CHECK_NOESCAPE): Move core functionality to...
11224 (_AT_CHECK): ...this new macro.
11226 2003-08-07 Derek Price <derek@ximbiot.com>
11228 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
11229 (AT_CHECK_NOESCAPE): ...to this new macro.
11231 2003-07-31 Paul Eggert <eggert@twinsun.com>
11233 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
11234 in Bash 2.01. Problem reported by Brian Gough in
11235 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
11237 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
11239 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
11240 -lcrt1.o, for OS X. (trivial change)
11242 2003-07-07 Paul Eggert <eggert@twinsun.com>
11244 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
11245 inside '#ifndef __cplusplus'. Problem reported by
11246 Bob Friesenhahn.
11248 2003-07-06 Bill Clarke <llib@computer.org>
11250 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
11251 'long', not 'int', for benefit of Sun's recent C++ compilers
11252 (trivial change). See:
11253 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
11254 (This really should be 'intptr_t', not 'long', but that would
11255 take more work.)
11257 2003-06-25 Akim Demaille <akim@epita.fr>
11259 * lib/Makefile.am (autom4te.cfg): Make it read only.
11260 Depend on Makefile since it contains substitutions.
11261 From Paolo Bonzini.
11262 * lib/autom4te.in (args): Add local.at? for Autotest args.
11263 This change was made on autom4te.cfg which is generated.
11264 Reported by Raja R. Harinath.
11266 2003-06-25 Akim Demaille <akim@epita.fr>
11268 * doc/autoconf.texi (Header Portability): sys/mount.h.
11269 From Gareth McCaughan.
11271 2003-06-23 Akim Demaille <akim@epita.fr>
11273 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
11274 not all of them. This fixes 1. the fact that when testing
11275 Autoconf there are many many config.log, 2. the incorrect use of
11276 top_srcdir to find config.log.
11277 Don't mix the detailed output of failed test with the summary of
11278 failures. Rather, append detailed log afterwards.
11280 2003-06-23 Akim Demaille <akim@epita.fr>
11282 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
11283 always run: output config.log on $at_group_log.
11285 2003-06-23 Akim Demaille <akim@epita.fr>
11287 * tests/torture.at (#define header templates): Don't use quotes in
11288 C++ comments as it puzzles Emacs' sh font-lock-mode.
11290 2003-06-23 Akim Demaille <akim@epita.fr>
11292 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
11293 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
11294 * tests/atspecific.m4: Rename as...
11295 * tests/local.at: This.
11296 * tests/suite.at: Move the globals into...
11297 * tests/local.at: here.
11298 * tests/Makefile.am: Adjust.
11299 * doc/autoconf.texi (testsuite Scripts): Adjust.
11301 2003-06-21 Kevin Ryde <user42@zip.com.au>
11303 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
11304 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
11305 ensuring we add -std1 for full-ANSI.
11307 * doc/autoconf.texi (hdrindex): New macro.
11308 Add index entries for portability of various standard header files.
11310 2003-06-20 Akim Demaille <akim@epita.fr>
11312 * configure.ac: Bump to 2.57b.
11314 2003-06-20 Akim Demaille <akim@epita.fr>
11316 Version 2.57a.
11318 2003-06-20 Akim Demaille <akim@epita.fr>
11320 * bin/autom4te.in: Don't rely on $HOME being defined.
11321 Reported by Marc Espie as PR/233.
11323 2003-06-20 Akim Demaille <akim@epita.fr>
11325 * lib/autotest/general.m4: Use at_times_file only if used.
11326 From Nicolas Joly.
11328 2003-06-20 Akim Demaille <akim@epita.fr>
11330 * config/config.guess, config/config.sub, config/elisp-comp,
11331 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
11332 Update from masters.
11334 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
11336 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
11337 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
11338 (TEST_SCRIPT): New diversion.
11339 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
11340 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
11341 (AT_INIT): Support for expected failures.
11343 2003-06-02 Akim Demaille <akim@epita.fr>
11345 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
11346 changes.
11347 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
11348 Autoconf nor Automake.
11349 (&contents): New, from Automake.
11350 PODify.
11352 2003-05-28 Paul Eggert <eggert@twinsun.com>
11354 * NEWS, doc/autoconf.texi (Particular Functions),
11355 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
11356 is the inverse of localtime.
11358 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
11360 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
11361 (handle_exec_errors): New function. Work around $! being
11362 altered by WEXITSTATUS.
11363 (xqx, xsystem): Use handle_exec_errors.
11365 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
11367 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
11368 Do not call `_exit()', simply modify `$?'.
11369 (xsystem): Reset $! before running system, and check it afterward.
11370 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
11371 63 for version mismatches.
11373 2003-05-23 Akim Demaille <akim@epita.fr>
11375 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
11376 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
11377 the middle of a line).
11378 * lib/m4sugar/m4sugar.m4: Likewise.
11379 Remove useless spaces in comments.
11381 2003-05-23 Akim Demaille <akim@epita.fr>
11383 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
11384 exit 63, so that we (or Automake's "missing") can tell the
11385 difference with a plain failure.
11386 * doc/autoconf.texi (Notices): Adjust.
11388 2003-05-23 Akim Demaille <akim@epita.fr>
11390 * Makefile.am, bin/Makefile.am, config/Makefile.am,
11391 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
11392 White spaces cleanup.
11394 2003-05-22 Jim Meyering <jim@meyering.net>
11395 Paul Eggert <eggert@twinsun.com>
11397 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
11398 Remove `#include <stdlib.h>' from the list; we should never
11399 make confdefs.h include <stdlib.h> or <cstdlib>, because the
11400 resulting namespace pollution would cause other tests to fail.
11401 Configure scripts run with some older versions of g++ and HP's
11402 aCC would fail due to such an #include. Problems reported by
11403 Matthew Mueller in <http://bugs.debian.org/120704> and by
11404 Keith Bostic in
11405 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
11406 In the test, use the test declaration before including <stdlib.h>,
11407 as that's closer to how it'll be used.
11409 2003-05-23 Akim Demaille <akim@epita.fr>
11411 * doc/autoconf.texi (Header Portability): ucred.h.
11412 From Ian Redfern.
11414 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11416 Overhaul Autotest's logging: generate separate log files
11417 in testsuite.dir/NNN/testsuite.log, and append them to
11418 testsuite.log instead of re-running the test verbosely.
11420 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
11421 file descriptor, write 0 to at_status_file instead of setting
11422 at_status=0, initialize some new variables (at_status_file,
11423 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
11424 to rerun the tests, instead append the at_group_log to the
11425 at_suite_log when a test fails.
11426 (AT_SETUP): pipe the test case's output into at_tee_pipe,
11427 with the AS_MESSAGE_LOG_FD redirected to stdout.
11428 (AT_CLEANUP): save the output status in $at_status_file
11429 and restore it, redirect the AS_MESSAGE_LOG_FD back to
11430 its original place.
11431 (AT_CHECK): since tests are run with a redirected stdout,
11432 and used to be re-run in verbose mode, turn some $at_verbose
11433 into echo, and don't redirect the output of testing stdout
11434 and stderr.
11436 * lib/autotest/autoconf.texi (testsuite Scripts): Update
11437 the name of the debugging directory and information about
11438 its contents.
11440 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
11442 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
11443 parameter.
11445 2003-05-22 Akim Demaille <akim@epita.fr>

11557 2003-05-06 Akim Demaille <akim@epita.fr>

11560 longer updates aclocal.m4 if useless, (ii) if a file m4_included
11561 by aclocal.m4 is changed it might require the importing of another
11562 m4 extension file, i.e., aclocal must be run.
11564 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
11565 (&parse_args): Use --force with aclocal if required and supported.

11583 (AT_CLEANUP): Add `;' to end of at_help_all.
11584 (AT_INIT): Allow --keywords to be specified more than once. When
11585 grepping $at_help_all for keywords, use the field and keyword
11586 seperators to ensure a complete keyword match. Alter at_prev handling

11591 * doc/autoconf.texi: Make the dir entries in the autoconf manual
11592 align better with others. I also made some of the individual

11665 * tests/torture.at (Configuring subdirectories): Require aclocal

11814 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
11815 innocuous variant befor including <limits.h> or <assert.h>. This
11816 works around a bug reported by Albert Chin: HP-UX 11i
11817 (and earlier versions) have a <limits.h> that declares
11818 gettimeofday and many other functions.
11820 2002-12-03 Paul Eggert <eggert@twinsun.com>

11832 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
11834 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
11835 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
11836 defined, to support freestanding compilers. This should fix the
11837 bug reported by Momchil Velkov in
11838 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
11840 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
11841 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

11876 * Makefile.maint: Sync with Bison, i.e.:
11877 (po-check): Scan .l and .y files instead of the
11878 .c and the .h files that they generate. This fixes the bug
11879 reported by Tim Van Holder in:
11880 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
11881 Look for N_ as well as for _. Try to avoid matching #define for

11902 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q

11938 2002-11-05 Akim Demaille <akim@epita.fr>
11940 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11941 Remove.
11942 We _have_ to stop using the old compatibility scheme that tried to
11943 avoid useless backslashes because Libtool 1.4.3 contains a
11944 AC_DEFINE([error_t], [int],
11945 [Define to a type to use for \`error_t' if it is not
11946 otherwise available.])
11947 We _have_ to quote the single quote and backslashes with \. The
11948 old compatibility scheme saw that ` was backslashed, and therefore
11949 did not quote the single quote. Hence before this patch, Autoconf
11950 was not compatible with Libtool.
11952 2002-11-04 Paul Eggert <eggert@twinsun.com>

12296 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

12341 Reported by Alexandre Duret-Lutz.
12343 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

12347 (&freeze): Use &error.
12348 (&up_to_date): If a file that was included according to the cache
12349 is no longer there, then the output is out dated.

12351 --force is given.

12361 that error messages can be easily located, and use GNU Make
12362 format, so that Emacs' compile mode understands us.
12363 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
12364 if some file was changed instead of `print'.
12365 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

12398 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
12399 file name to enable parallel executions.
12400 From Sam Varshavchik.
12402 2002-10-08 Akim Demaille <akim@epita.fr>
12404 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
12405 aclocal invocation, as Gettext macros might not be visible to
12406 aclocal.
12407 Instead of blindly running autopoint, scan configure.ac (not the

12409 Reported by Paul D. Smith.
12411 2002-10-08 Paul Eggert <eggert@twinsun.com>
12413 Work around problems found when POSIXLY_CORRECT=1 is set.
12414 None of this seems to have anything to do with POSIX, really,
12415 but it's how Perl getopt works.
12416 * bin/autom4te.in (parse_args): Configure GetOpt with
12417 "permute", too.
12418 * doc/autoconf.texi (Invoking autom4te):
12419 --warning -> --warnings.
12420 * lib/autom4te.in: --warning -> --warnings.
12422 2002-09-28 Akim Demaille <akim@epita.fr>
12424 * doc/autoconf.texi (autom4te.cache): New section.
12426 2002-09-28 Akim Demaille <akim@epita.fr>
12428 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
12429 (Automake-preselections): Update.
12430 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
12432 2002-09-28 Akim Demaille <akim@epita.fr>
12434 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
12435 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
12436 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12437 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
12439 2002-09-28 Akim Demaille <akim@epita.fr>
12441 * tests/torture.at (Configuring subdirectories): Be robust to
12442 users who use config.site to require for a cache: in this case,
12443 the two last configure runs, using two different sets of
12444 arguments, trigger a legitimate error.
12446 2002-09-28 Akim Demaille <akim@epita.fr>
12448 * tests/m4sh.at (Functions Support, Functions and return Support):
12449 New.
12451 2002-09-28 Akim Demaille <akim@epita.fr>
12453 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
12454 autoheader are Perl programs.
12455 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
12456 (autom4te): Specify that the sources are in the $srcdir.
12457 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12459 2002-09-28 Akim Demaille <akim@epita.fr>
12461 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
12462 (tm_zone): Move their rules to...
12463 * lib/autoconf/types.m4: here, using AN_ macros.
12464 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
12465 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
12466 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
12467 * lib/autoconf/programs.m4: here.
12468 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
12469 (ETAGS_FOR_AUTOCONF): New.
12470 Use it.
12472 2002-09-28 Akim Demaille <akim@epita.fr>
12474 * lib/autoconf/autoscan.m4: New file.
12475 * lib/autoconf/autoconf.m4: Include it.
12476 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
12477 that were listed in the original autoscan.list.
12478 * lib/autoconf/headers.m4: Similarly with headers.
12479 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
12480 (.m4.m4f): Don't pass --prepend-include, since that's done by
12481 tests/autom4te itself.
12482 * lib/autoscan/Makefile.am: Include freeze.mk.
12483 (autoscan.list): New target --this file is no longer a source.
12484 (autoscan.pre): New file.
12486 2002-09-28 Akim Demaille <akim@epita.fr>
12488 * bin/autoscan.in (@kinds): Make them singular.
12489 Adjust all uses.
12490 (&init_tables): When --debug, report the list of rules to ease
12491 tracking changes in autoscan.list.
12492 * lib/autoscan/autoscan.list (function): Strip comments, sort.
12494 2002-09-28 Akim Demaille <akim@epita.fr>
12496 * lib/autoscan/functions, lib/autoscan/headers,
12497 * lib/autoscan/identifiers, lib/autoscan/makevars,
12498 * lib/autoscan/programs: Merge into...
12499 * lib/autoscan/autoscan.list: this.
12500 * bin/autoscan.in (&init_tables): Adjust.
12502 2002-09-28 Akim Demaille <akim@epita.fr>
12504 * lib/autoscan/functions, lib/autoscan/headers,
12505 * lib/autoscan/identifiers, lib/autoscan/makevars,
12506 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
12507 `functions' line is now prefixed with `function:'.
12508 * bin/autoscan.in (&init_tables): Adjust.
12510 2002-09-28 Akim Demaille <akim@epita.fr>
12512 From now on, autoscan files must always map a macro name to a
12513 word: there is no `default' macro for autoscan.
12515 * bin/autoscan.in (&init_tables): Reject entries with no macro at
12516 all.
12517 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
12518 explicit.
12520 2002-09-28 Akim Demaille <akim@epita.fr>
12522 * bin/autoscan.in (%c_keywords): Remove.
12523 (&used): Keep only track of the words we might be interested in.
12524 (&output_kind): It is no longer needed to look for non active
12525 checks.
12527 2002-09-27 Akim Demaille <akim@epita.fr>
12529 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
12530 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
12531 * lib/autoscan/functions: Adjust.
12532 * doc/autoconf.texi (Particular Functions): Adjust.
12534 2002-09-27 Akim Demaille <akim@epita.fr>
12536 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
12537 from /tmp.
12538 Thanks to Bill Moseley and Paul Eggert.
12539 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
12540 the tmpdir must be created.
12541 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
12542 dir be in the build tree, instead of $TMPDIR.
12544 2002-09-27 Akim Demaille <akim@epita.fr>
12546 * bin/autoscan.in: Improve the comments.
12547 (&parse_args): Drop obsolete undocumented options.
12548 (&output_kind): Output warnings.
12549 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
12550 (getwd): Trigger a warning.
12552 2002-09-26 Akim Demaille <akim@epita.fr>
12554 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
12555 Reported by Ralf Corsepius.
12556 * doc/autoconf.texi (autoreconf Invocation): Likewise.
12558 2002-09-26 Akim Demaille <akim@epita.fr>
12560 Single suffix rules and seperated dependencies are not portable.
12562 * doc/autoconf.texi (Installation Directory Variables): Update.
12563 (Limitations of Make): Some about `Single Suffix Rules and
12564 Separated Dependencies'.
12565 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12566 (ifnames, autoscan, autom4te): Un-factor into several rules.
12568 2002-09-25 Paul Eggert <eggert@twinsun.com>
12570 * BUGS (Interoperability bugs): New section. Mention libtool
12571 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
12573 2002-09-24 Paul Eggert <eggert@twinsun.com>
12575 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
12576 make handles suffix-rules differently from GNU make.
12578 * bin/Makefile.am (SUFFIXES, .in): Remove.
12579 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
12580 Move the body of the old .in rule here.
12582 2002-09-16 Akim Demaille <akim@epita.fr>
12584 i960 compilers create `b.out' files by default.
12585 Reported by Ralf Corsepius.
12587 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
12588 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
12590 2002-09-13 Paul Eggert <eggert@twinsun.com>
12592 * doc/autoconf.texi (Particular Headers): Remove obsolete
12593 reference to `struct timezone' in the description of
12594 AC_HEADER_TIME.
12596 2002-09-13 Akim Demaille <akim@epita.fr>
12598 Version 2.54.
12600 * config/config.sub, config/config.guess: Update.
12601 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
12602 * Makefile.am: Adjust.
12604 2002-09-13 Akim Demaille <akim@epita.fr>
12606 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
12607 reading config.log when the compiler is rejected.
12608 Suggested by Guido Draheim.
12610 2002-09-13 Akim Demaille <akim@epita.fr>
12612 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
12613 (chdir_init) might hang when stat'ing mounted directories.
12614 Reported by Vance Shipley.
12616 2002-09-12 Akim Demaille <akim@epita.fr>
12618 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
12619 the lists.
12621 2002-09-12 Akim Demaille <akim@epita.fr>
12623 * doc/autoconf.texi (Defining Symbols): Present two different
12624 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
12625 difference between 1 argument calls, and 2-3 argument calls.
12627 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
12629 * doc/autoconf.texi: Review grammar and punctuation.
12631 2002-09-11 Paul Eggert <eggert@twinsun.com>
12633 * doc/autoconf.texi: Fix minor formatting, spelling, and
12634 grammatical typos.
12635 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
12636 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
12637 is obsolescent.
12639 2002-09-11 Akim Demaille <akim@epita.fr>
12641 * doc/autoconf.texi (Questions): Rename as...
12642 (FAQ): this.
12643 (Defining Directories): New.
12645 2002-09-09 Akim Demaille <akim@epita.fr>
12647 * doc/autoconf.texi (Making testsuite Scripts): Update.
12648 Suggested by Nishio Futoshi.
12650 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
12652 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
12653 plain `@' is wanted.
12655 2002-09-09 Akim Demaille <akim@epita.fr>
12657 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
12658 `duplicates', since the algorithm was too naive and could keep
12659 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
12660 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
12661 Reported by Ralf Corsepius.
12662 * tests/torture.at (Configuring subdirectories): Exercise these
12663 cases.
12665 2002-09-09 Akim Demaille <akim@epita.fr>
12667 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
12668 looking for a replacement file.
12669 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
12670 directory is relative.
12671 * doc/autoconf.texi (Generic Functions): Clarify the replacement
12672 directory definition.
12673 Reported by Andreas Schwab and Jim Meyering.
12675 2002-09-06 Akim Demaille <akim@epita.fr>
12677 * doc/autoconf.texi (Setting Output Variables): Clarify what
12678 precious variables are.
12679 Suggested by Pontus Skoeld.
12681 2002-09-05 Akim Demaille <akim@epita.fr>
12683 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
12684 (ifnames, autoscan, autom4te): Since we don't only depend on
12685 configure.ac variables (such as VERSION etc.), but also on prefix
12686 and so forth, depend on Makefile, not configure.ac.
12687 Reported by Alexandre Duret-Lutz.
12688 * doc/autoconf.texi (Installation Directory Variables): Adjust.
12690 2002-09-05 Kevin Ryde <user42@zip.com.au>
12692 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
12693 doesn't seem to be confined to ia64, just say "some versions".
12695 2002-09-04 Akim Demaille <akim@epita.fr>
12697 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
12698 Automake 1.6c.
12699 * Makefile.am (maintainer-clean-local): Remove.
12700 (MAINTAINERCLEANFILES): Remove COPYING.
12702 2002-09-03 Paul Eggert <eggert@twinsun.com>
12704 * doc/autoconf.texi (Configuration Commands): Remove obsolete
12705 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
12706 Brinkmann.
12708 2002-09-03 Akim Demaille <akim@epita.fr>
12710 * configure.ac: Bump to 2.53d.
12711 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
12712 as of today, on Automake's team suggestion.
12714 2002-09-03 Akim Demaille <akim@epita.fr>
12716 Version 2.53c.
12718 2002-09-02 Akim Demaille <akim@epita.fr>
12720 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
12721 SITE_MACRO_DIR.
12722 * configure.ac: Disable SITE_MACRO_DIR.
12724 2002-09-02 Jim Meyering <meyering@lucent.com>
12726 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
12727 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
12728 Also, tweak grammar: s/make sure to/be sure to/.
12730 2002-09-02 Paul Eggert <eggert@twinsun.com>
12732 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
12733 directory names are generally preferable to physical names.
12735 2002-09-02 Akim Demaille <akim@epita.fr>
12737 * lib/Autom4te/General.pm (&update_file): s/die/error/.
12738 Reported by Raja R. Harinath.
12739 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
12740 * bin/autoupdate.in: Use error instead of die.
12742 2002-09-01 Paul Eggert <eggert@twinsun.com>
12744 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
12745 ordinary shell concatenation rather than echo+tr+sed command that
12746 runs afoul of a long-line-related sed bug in Solaris 8.
12748 * bin/autoheader.in (parse_args): --warning -> --warnings.
12750 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
12751 stdout, as traditional "ls" does.
12752 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
12753 _AC_COMPILER_EXEEXT_O): Likewise.
12754 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
12756 * bin/autoconf.as: Add --prepend-include option. This patch was
12757 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
12758 but bin/autoconf.in is generated automatically from bin/autoconf.as.
12760 * bin/autoconf.in, configure: Regenerate.
12762 * doc/autoconf.texi (Special Shell Variables): Mention
12763 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
12765 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
12766 MAILPATH and set PS1, PS2, PS4 to default values, to work
12767 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
12768 For LC_ALL etc, first try to set to "C" as POSIX requires and as
12769 the Autoconf documentation specifies; fall back to "unset" only if
12770 this fails. Use a shell for-loop for this rather than an m4 loop,
12771 to shorten the output script.
12773 2002-08-30 Paul Eggert <eggert@twinsun.com>
12775 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
12776 1003.1-2001's requirements for CDPATH. Give a simpler workaround
12777 for the CDPATH problem. Document PWD.
12778 (Limitations of Builtins): Document the problem that "cd $foo" and
12779 "ls $foo" may refer to different directories in shells conforming
12780 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
12781 example, since the old example is now out of date.
12783 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
12784 FOO" and "ls FOO" talk about different directories; this catches
12785 problems when POSIX 1003.1-2001 "cd" fails due to symlink
12786 spaghetti.
12788 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
12789 of rolling our own unset.
12790 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
12791 in practice we needn't worry about CDPATH if unset doesn't work.
12793 * Makefile.in, aclocal.m4, bin/Makefile.in,
12794 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
12795 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
12796 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
12797 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
12798 tests/Makefile.in: Regenerate with Automake 1.6.3.
12800 * config/config.guess, config/config.sub, config/mkinstalldirs:
12801 Update.
12803 * configure: Regenerate with self.
12805 2002-08-30 Kevin Ryde <user42@zip.com.au>
12807 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
12808 default output.
12810 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
12812 * bin/autom4te.in (Request::load): Correctly test for "do" read
12813 failure.
12815 2002-08-29 Akim Demaille <akim@epita.fr>
12817 * lib/Autom4te/General.pm (&xqx): New.
12818 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
12819 hand, which is not portable.
12820 (&error): New.
12821 * bin/autom4te.in: Use them.
12822 Use &error instead of die.
12823 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
12824 Adjust.
12826 2002-08-17 Paul Eggert <eggert@twinsun.com>
12828 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
12829 default list of compilers to try, since it was long ago superseded
12830 by the ksh fc builtin. Suggested by Steven G. Johnson.
12832 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
12834 * doc/autoconf.texi (Invoking autom4te): End the option table,
12835 fixing a bug introduced by the previous patch.
12836 (Limitations of Make): Add a 'target lookup' subentry in the
12837 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
12839 2002-07-29 Mark D. Roth <roth@feep.net>
12841 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
12842 options and use $AUTOM4TE_PATH.
12843 * doc/autoconf.texi: Remove documentation of autom4te
12844 --include-envvar and --site-macro-subdir options and document
12845 use of $AUTOM4TE_PATH.
12846 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
12847 arguments from each language section.
12849 2002-07-29 Paul Eggert <eggert@twinsun.com>
12851 * doc/install.texi: Include copyright symbol in copyright notice.
12853 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
12854 Replace with:
12855 (AM_MAKEINFOFLAGS): New macro.
12856 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
12857 * Makefile.am (INSTALL): Use the new macros.
12858 Use -o rather than --output, since "missing" does not grok --output.
12860 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12862 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
12863 comments do not always work. Never trust the exit status of
12864 `make -k'.
12866 2002-07-24 Kevin Ryde <user42@zip.com.au>
12868 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
12869 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
12871 2002-07-23 Paul Eggert <eggert@twinsun.com>
12873 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
12874 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
12875 apparently treats PATH="nonexistent" as if it contained ".".

13014 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
13015 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
13016 so that we consistently test the just-built programs.
13017 * tests/wrappl.as: Likewise.

13037 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
13039 * bin/autom4te.in ($cache): Don't define using `$me', the name

13059 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
13060 AC_FUNC_FNMATCH_GNU.

13071 Suggested by Adam J. Richter.
13073 2002-06-07 Akim Demaille <akim@epita.fr>
13075 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
13076 ac_config_libobj_dir.
13077 (AC_CONFIG_LIBOBJ_DIR): New.
13078 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
13079 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
13080 Use ac_config_libobj_dir to find the replacement files.
13081 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

13086 * tests/mktests.sh (ac_exclude_list): Don't check

13100 Update from masters.
13102 2002-05-29 Paul Eggert <eggert@twinsun.com>

13114 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
13115 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
13117 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
13118 * doc/autoconf.texi (Particular Programs): Document them.

13125 * NEWS, doc/autoconf.texi (Particular Types): Document it.
13126 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
13127 instead of AC_MBSTATE_T, which never existed.
13129 2002-05-23 Akim Demaille <akim@epita.fr>
13131 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
13132 version of Autoconf that is discussed.
13134 2002-05-22 Paul Eggert <eggert@twinsun.com>
13136 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
13137 from the default list of compilers to try. Suggested by
13138 Kate Hedstrom.
13139 * NEWS: Document the above.
13140 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
13142 2002-05-17 Paul Eggert <eggert@twinsun.com>
13144 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
13145 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
13146 This improves on an earlier suggestion by H. Peter Anvin.
13148 2002-05-16 Paul Eggert <eggert@twinsun.com>
13150 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
13151 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
13152 Both macros now accept an optional source-dir arg.
13153 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
13155 * NEWS: Document this.
13156 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
13158 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
13159 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
13160 not for GNU extensions; this undoes part of the 2000-11-03 change,
13161 reverting to 2.13-compatible behavior.
13162 Add new optional argument DIR.
13163 (AC_FUNC_FNMATCH_GNU): New macro.
13165 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
13167 2002-05-08 Paul Eggert <eggert@twinsun.com>
13169 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
13170 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
13171 and it causes a 'test' syntax error if it fails.
13172 Bug reported by Stephen Gildea.
13174 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
13175 If prototypes are supported, use them to check this at compile-time,
13176 instead of trying to check it at run-time. If we must do a run-time
13177 check, assume that setvbuf is standard when cross-compiling, as
13178 nonstandard setvbuf occurs only on ancient and unlikely hosts.
13179 Bug reported by Paul D. Smith.
13181 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
13182 argument specifying location of getloadavg.c. This removes a
13183 FIXME. This idea was taken from Jim Meyering's implementation in
13184 textutils.
13185 * doc/autoconf.texi (Particular Functions): Document this.
13186 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
13187 that's what the code does; this fixes a bug reported by
13188 Paul D. Smith.
13190 2002-05-03 Akim Demaille <akim@epita.fr>
13192 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
13193 autopoint instead of gettextize.
13194 ($uses_alocal): Rename as...
13195 ($uses_aclocal): this.
13196 * doc/autoconf.texi (autoreconf Invocation): Adjust.
13197 Suggested by Bruno Haible.
13199 2002-05-03 Akim Demaille <akim@epita.fr>
13201 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
13203 2002-04-29 Paul Eggert <eggert@twinsun.com>
13205 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
13206 files to be 1 second older; just set them to be the same time.
13207 Also, sleep 1 second after the first aclocal, to work around
13208 problems with sub-second time stamps on the input files.
13210 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
13212 * doc/autoconf.texi: Mention "set -e -x" lossage
13213 under node "Limitations of Builtins".
13215 2002-04-29 Akim Demaille <akim@epita.fr>
13217 * doc/install.texi: Better wording for setting variables when
13218 running configure.
13219 From Christian Cornelssen.
13221 2002-04-29 Akim Demaille <akim@epita.fr>
13223 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
13224 of lack of $LINENO support, then the test will compare the $LINENO
13225 in testsuite vs. the lineno in the test file. This is wrong, of
13226 course.
13227 Be sure to protect it.
13228 Reported by Patrick Welche.
13230 2002-04-25 Akim Demaille <akim@epita.fr>
13232 * doc/autoconf.texi (Obsolete Macros): Typo.
13233 Reported by Vladimir Volovich.
13235 2002-04-25 Akim Demaille <akim@epita.fr>
13237 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
13238 than some of the input files, hence, on the second run of aclocal,
13239 if some of its input are younger, make them older.
13240 Suggested by Paul Eggert.
13242 2002-04-25 Akim Demaille <akim@epita.fr>
13244 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
13245 Thanks to Paul Eggert.
13247 2002-04-25 Akim Demaille <akim@epita.fr>
13249 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
13250 and ac_subst_vars be sh variables containing the list of
13251 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
13252 DEFAULT diversion.
13253 (_AC_INIT_PREPARE): Use them to log them.
13254 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
13255 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
13256 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
13257 _AC_SUBST_FILES and _AC_SUBST_VARS.
13258 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
13260 2002-04-24 Akim Demaille <akim@epita.fr>
13262 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
13263 autoheader, so that automake does not complain about a missing
13264 config.h.in that was to be created.
13266 2002-04-23 Akim Demaille <akim@epita.fr>
13268 * bin/autoheader.in (parse_args): --warning takes an argument.
13269 Fixes PR/220.
13271 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
13273 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

13288 Reported by Gregory Giannoni.
13290 2002-04-22 Akim Demaille <akim@epita.fr>
13292 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
13293 Fixes false failures on Darwin.

13320 * doc/autoconf.texi: Follow the outline suggested in the GNU
13321 Sample Texts sections of the Texinfo 4.2 manual. Most
13322 importantly, this makes sure that the copyright notices appear in
13323 all output formats. You probably need Texinfo 4.2 to generate

13362 workaround for ${1+"$@"}.
13363 * doc/autoconf.texi (Shell Substitutions): Explain it.
13364 From Oliver Kiddle and Peter Stephenson.
13366 Have M4sh perform minimal shell sanitizing.
13368 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
13369 part into...
13370 (_AS_PREPARE): this new macro.
13371 (AS_PREPARE): New.
13372 (AS_INIT): Invoke AS_SHELL_SANITIZE.
13373 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
13375 Adjust Autoconf and Autotest.
13377 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
13378 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
13379 * lib/autotest/general.m4 (AT_INIT): Likewise.
13380 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
13381 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
13382 AS_SHELL_SANITIZE.
13384 Use this M4sh to generate Autoconf's shell scripts.
13386 * tests/wrapsh.as: New, precursor of wrapsh.in.
13387 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
13388 on Autotest and M4sh.
13389 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
13390 (wrapsh.in): New target.
13391 * bin/autoconf.as: New, precursor of autoconf.in.
13392 (autoconf.in): New target.
13394 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
13396 * doc/autoconf.texi (Limitations of Make): Mention the issue
13397 with indented comments in rules.
13399 2002-04-09 Andreas Schwab <schwab@suse.de>
13401 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
13402 ac_top_builddir when setting ac_abs_top_builddir.
13404 2002-04-06 Kevin Ryde <user42@zip.com.au>
13406 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
13407 (Portable Shell): Cross reference to Systemology.

13413 Reported by Ezra Peisach.

13417 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
13418 contains no literal separators.
13420 2002-04-03 Akim Demaille <akim@epita.fr>
13422 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
13423 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
13424 Use dnl, not the KILL diversion.
13425 Extracted from...
13426 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
13427 (AC_CONFIG_LINKS): here.
13428 Adjust.
13429 Don't use the KILL diversion, as it kills spurious output, which
13430 results in failures being hidden.
13431 Use m4_defn where appropriate.
13432 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
13433 after the second argument.
13434 Use m4_defn.
13435 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
13436 syntax, as it is provided by M4sugar.
13437 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
13439 2002-04-03 Andreas Schwab <schwab@suse.de>

13454 Fixes Debian #138666.
13456 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
13458 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
13460 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
13461 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
13462 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
13463 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
13464 (AC_C_CONST): Same.

13476 2002-03-28 Kevin Ryde <user42@zip.com.au>
13478 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
13479 to avoid versions of HP C which don't allow that.
13481 2002-03-27 Paul Eggert <eggert@twinsun.com>
13483 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
13484 (AS_SHELL_SANITIZE): Invoke it.
13485 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
13487 2002-03-26 Akim Demaille <akim@epita.fr>
13489 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
13491 2002-03-26 Akim Demaille <akim@epita.fr>
13493 * doc/autoconf.texi (Introduction): The GNATS base moved.
13495 2002-03-25 Paul Eggert <eggert@twinsun.com>
13497 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
13498 as POSIX requires, as it doesn't work with Zsh.
13499 * doc/autoconf.texi (Assignments): Document the problem.
13501 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
13503 * doc/autoconf.texi (Limitations of Make): Mention more issue
13504 about VPATH, overriding of macros in sub-makes, and handling of
13505 SHELL.
13507 2002-03-21 Paul Eggert <eggert@twinsun.com>
13509 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
13510 problem with here-document buffer boundaries.
13512 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
13513 when reinvoking the shell, to work around problems with installers
13514 who put strange things like "cd" commands in their environments.
13516 2002-03-19 Akim Demaille <akim@epita.fr>
13518 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
13519 From Aaron Ucko.
13521 2002-03-19 Akim Demaille <akim@epita.fr>
13523 * bin/autoscan.in (scan_file): Specify the location in `&used'
13524 invocations.
13525 From Nicolas Joly.
13527 2002-03-19 Akim Demaille <akim@epita.fr>
13529 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
13530 From Nishio Futoshi.
13532 2002-03-19 Akim Demaille <akim@epita.fr>
13534 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
13536 2002-03-18 Paul Eggert <eggert@twinsun.com>
13538 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
13539 (Limitations of Usual Tools): Add mkdir section.
13541 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
13542 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
13543 back on AS_DIRNAME to compute prefixes otherwise; this is
13544 roughly what mkinstalldirs does. That way, we need not have
13545 our own filename disassembler. The old disassembler did not
13546 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
13548 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
13549 Create at_test_all by a series of assignments,
13550 not by a single assignment of a long string. The latter causes ksh
13551 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
13552 presumably because of a buffer overrun.
13554 2002-03-14 Paul Eggert <eggert@twinsun.com>
13556 * lib/autotest/general.m4 (at_times_skip):
13557 Renamed from at_times. Now a boolean.
13558 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
13559 says 'times: not found'.
13561 2002-03-14 Akim Demaille <akim@epita.fr>
13563 * bin/autoreconf.in (&study_gettextize): New.
13564 (&autoreconf): Handle newest gettextize.
13565 Rerun aclocal if needed.
13566 Suggested by Andreas Schwab.
13568 2002-03-13 Akim Demaille <akim@epita.fr>
13570 * doc/autoconf.texi (Special Shell Variables): More about IFS.
13572 2002-03-13 Akim Demaille <akim@epita.fr>
13574 * doc/autoconf.texi (Header Portability): New.
13575 Add information about stdint.h and inttypes.h from Paul Eggert.
13577 2002-03-13 Akim Demaille <akim@epita.fr>
13579 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
13580 -p'.
13581 From Bob Proulx.
13583 2002-03-12 Akim Demaille <akim@epita.fr>
13585 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
13586 m4_require.
13588 2002-03-11 Andreas Schwab <schwab@suse.de>
13590 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
13591 does not do it if --with-lispdir is given.
13593 2002-03-08 Akim Demaille <akim@epita.fr>
13595 Version 2.53.
13597 2002-03-08 Akim Demaille <akim@epita.fr>
13599 * doc/autoconf.texi (Subdirectories): Clarify that the
13600 subdirectory should exist.
13602 2002-03-08 Akim Demaille <akim@epita.fr>
13604 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
13606 2002-03-08 Akim Demaille <akim@epita.fr>
13608 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
13609 aliases the actual variables, and modifications of the former
13610 affect the latter.
13612 2002-03-08 Akim Demaille <akim@epita.fr>
13614 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
13615 because of C-c: have m4 output in tmp files, then mv them.
13617 2002-03-08 Akim Demaille <akim@epita.fr>
13619 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
13620 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
13621 * bin/ifnames.in: Copyright update.

13627 2002-03-05 Akim Demaille <akim@epita.fr>

13630 Kevin Ryde.
13632 2002-03-05 Akim Demaille <akim@epita.fr>
13634 Version 2.52i.
13636 2002-03-04 Akim Demaille <akim@epita.fr>
13638 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
13639 * lib/autoconf/general.m4 (AC_INIT): More informative error
13640 message for LIBOBJ.
13642 2002-03-04 Akim Demaille <akim@epita.fr>
13644 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
13645 parallel builds.
13647 2002-03-04 Akim Demaille <akim@epita.fr>
13649 * doc/autoconf.texi (Transforming Names): Equality between target
13650 and host is irrelevant.
13651 (Specifying Names, Canonicalizing): Remove all references to the
13652 backward compatibility hooks. Rather, collect them all into...
13653 (Hosts and Cross-Compilation): this new section.
13654 * doc/install.texi (System Type): Ditto.
13655 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
13656 that `--host' implies cross-compilation.
13658 2002-03-04 Akim Demaille <akim@epita.fr>
13660 * doc/autoconf.texi (Evaluation Macros): New.
13661 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
13662 useless.
13663 (_m4_foreach): Define the variant with immediate evaluation so
13664 that it contains exactly the items, not an expression which
13665 evaluation is the current item.
13666 (m4_re_string, m4_re_word): Don't over quote them.
13668 2002-03-04 Akim Demaille <akim@epita.fr>
13670 Instead of having stacking `shift's evaluated at the end, let
13671 `foreach' loops immediately evaluate them.
13673 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
13674 $*. This is the n-th time I change my mind, but hopefully this is
13675 the last...
13676 (m4_lquote): New.
13677 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
13678 efficient.
13679 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
13680 it was only a hack for m4_text_wrap.
13681 (m4_car2): Remove, replaced by...
13682 (m4_cdr): New.
13683 (_m4_foreach): Adjust.
13684 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
13685 m4_bpatsubst for clarification.

13729 Fix Autoconf PR/209.
13730 Also reported by Frank Denis.
13732 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
13734 2002-02-07 Akim Demaille <akim@epita.fr>

13778 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

13800 * bin/autom4te.in (&parse_args): Implement `frozen files are
13801 optional are the sum of the previous files on the command line'.
13802 Also, pass `--reload-state=' on them, so...
13803 (handle_m4): don't.
13804 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
13805 (M4sh): Rely on M4sugar.
13806 (Autotest, M4sh, M4sugar): Use frozen files.
13808 2002-01-31 Akim Demaille <akim@epita.fr>
13810 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
13811 * doc/autoconf.texi (Initializing configure): Adjust.
13813 2002-01-30 Akim Demaille <akim@epita.fr>
13815 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
13816 alphanumeric to `-' instead of `_'.
13818 2002-01-30 Akim Demaille <akim@epita.fr>
13820 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
13821 for plain code, the other for cross-compilation code. The latter
13822 is now run with GCC only.
13823 * doc/autoconf.texi (Compilers and Preprocessors): New.

13834 * tests/torture.at (Configuring subdirectories): Use configure.in,
13835 so that aclocal 1.4 works.
13836 Reported by Alexandre Duret-Lutz and Larry Schmitt.
13838 2002-01-28 Akim Demaille <akim@epita.fr>
13840 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
13841 needs an argument.
13843 2002-01-28 Akim Demaille <akim@epita.fr>
13845 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
13846 AUTOTEST_PATH *after* it was set.
13847 Don't put `.' in the PATH: the user should be precise and `./' if
13848 needed. In addition, given that the test suite does some `cd', if
13849 `.' is in the path, the `tested programs' sections will report
13850 programs found in the test suite's directory, while during the
13851 tests (performed in their own directory), these programs are no
13852 longer visible. In other words, the results is confusing and
13853 useless.
13854 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
13856 2002-01-24 Akim Demaille <akim@epita.fr>
13858 Version 2.52g.

13863 * doc/autoconf.texi: Finally add Akim as an author.
13865 2002-01-24 Akim Demaille <akim@epita.fr>
13867 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
13868 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
13869 Bourne. Use /bin/sh.
13870 From Andreas Buening.
13872 2002-01-24 Akim Demaille <akim@epita.fr>
13874 * config/config.guess, config/config.sub, config/texinfo.tex:

13883 * config/strip.m4: Remove, to ease sync'ing with any version of
13884 Automake.
13886 2002-01-24 Akim Demaille <akim@epita.fr>
13888 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13889 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13890 Reported by Geir Ove Myhr.
13892 2002-01-21 Akim Demaille <akim@epita.fr>
13894 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13896 2002-01-21 Akim Demaille <akim@epita.fr>
13898 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13899 message on invalid options.
13900 * bin/autom4te.in (parse_args): Don't use
13901 Autoconf::General::getopt with non valid options.
13903 2002-01-17 Jim Meyering <meyering@lucent.com>
13905 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13906 $ac_cv_exeext so we don't use an old, invalid, cached value.
13908 2002-01-11 Akim Demaille <akim@epita.fr>
13910 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

13919 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13920 package.m4, since is really depends upon configure.ac, not
13921 configure.
13922 * doc/autoconf.texi (testsuite Scripts): Adjust.
13923 * tests/Makefile.am (package.m4): New.
13924 EXTRA_DIST it since its a source.
13926 2002-01-06 Akim Demaille <akim@epita.fr>
13928 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13929 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13930 and PACKAGE_BUGREPORT from here...
13931 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13932 arguments.
13933 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13934 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13935 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13936 * tests/tools.at (autoheader): Adjust.
13937 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

13951 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13952 sometimes needing writable input.
13954 2001-12-17 Jim Meyering <meyering@lucent.com>
13956 * doc/autoconf.texi (New Macros): Tweak wording.
13958 2001-12-14 Akim Demaille <akim@epita.fr>
13960 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13961 trailing files, don't apply `-rf' to files which might not be
13962 created by configure (core, core.*, and *.core), but just `rm -f'.
13963 Suggested by Jonathan Kamens.
13965 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13967 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13969 2001-12-14 Akim Demaille <akim@epita.fr>
13971 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13973 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13975 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13976 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13977 abs_srcdir, top_srcpath to abs_top_srcdir.
13978 (_AC_OUTPUT_FILES): Adjust.
13979 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13980 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13981 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13983 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13985 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13986 C/Fortran linking on HP/UX, by extracting the Fortran library
13987 search path from the LPATH line in the $F77 -v output.
13989 2001-12-12 Kevin Ryde <user42@zip.com.au>
13991 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13992 forbidden file descriptors table.
13994 2001-11-26 Akim Demaille <akim@epita.fr>
13996 * bin/autoscan.in (%c_keywords): Build it at top level.
13997 Map to 1 in order to simplify its uses.
13999 2001-11-26 Akim Demaille <akim@epita.fr>
14001 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
14002 Remove $filepath, useless.
14003 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
14004 variables, they are really part of the tokens.
14005 Split the input line on spaces and then look for tokens.
14006 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
14007 because of `lex$U.$(OBJEXT)'.
14008 (&scan_files): Use "@list" instead of join.
14009 * doc/Makefile.am (CLEANFILES): Add *.fns.
14011 2001-11-26 Akim Demaille <akim@epita.fr>
14013 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
14014 Remove, replaced by...
14015 * tests/wrappl.in: Be common for all the Perl executables.
14016 In particular autoscan and autoheader want -I.
14017 * configure.ac: Adjust.
14018 * lib/autoscan/headers: errno.h is portable.
14020 2001-11-26 Akim Demaille <akim@epita.fr>
14022 * bin/autoscan.in (used): New.
14023 Use it.

14028 directives.
14029 (&scan_sh_file): Remove a duplicate pattern.
14030 (&check_configure_ac): Use long options.
14031 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
14033 2001-11-26 Akim Demaille <akim@epita.fr>
14035 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
14036 Before, having a line containing the opening of a multi line
14037 comment made the whole line be ignored.
14039 2001-11-26 Akim Demaille <akim@epita.fr>
14041 * doc/autoconf.texi (Using an Autotest Test Suite): New.
14042 (testsuite Scripts): Be one of its subsection.
14043 (Autotest Logs): New.
14045 2001-11-26 Akim Demaille <akim@epita.fr>
14047 Test groups are now run two directories deeper.
14049 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
14050 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
14051 at_top_builddir.
14052 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
14053 top_srcdir, builddir and top_builddir.
14054 Use `at_*dir' relatively to the directory containing the
14055 suite, use `*dir' when relatively to the current group dir.
14057 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
14059 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
14060 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
14061 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
14062 spelling errors.
14064 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14066 * doc/autoconf.texi (Using System Type): Add an example of `case
14067 $host' usage so people quit using `case $target' everywhere.
14069 2001-11-22 Akim Demaille <akim@epita.fr>
14071 * doc/autoconf.texi (Installation Directory Variables): Englishoes
14072 spotted by Jim Meyering.
14074 2001-11-16 Paul Eggert <eggert@twinsun.com>
14076 This patch implements a `long double' suggestion by Oliver Kiddle.
14078 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
14079 static, to catch errors if the value isn't known at compile-time
14080 and the compiler supports dynamic arrays. Change its name from
14081 `_array_' to `test_array' to avoid potential name clashes.
14082 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
14083 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
14084 better than double. Catch a bug in GCC 2.95.2 x86.
14085 * doc/autoconf.texi (C Compiler): Document the above.
14086 * NEWS: Likewise.
14088 2001-11-13 Akim Demaille <akim@epita.fr>
14090 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
14091 hand.
14092 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
14094 2001-11-13 Akim Demaille <akim@epita.fr>
14096 * lib/autotest/general.m4 (AT_INIT): After having run the test
14097 group, go back to the initial directory, not to at_suite_dir.
14099 2001-11-13 Akim Demaille <akim@epita.fr>
14101 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
14102 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
14103 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
14104 option.
14105 (AT_CHECK_CONFIGURE): Use absolute paths.
14106 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
14107 The problem is still the old one: there is no means in M4 (that I
14108 know about) to create a defining macro, because there is no means
14109 to create `$1' etc., therefore, the defining macro ``swallows''
14110 all the arguments meant to the defined macro.
14112 2001-11-13 Akim Demaille <akim@epita.fr>
14114 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
14115 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
14116 configure.ac.
14117 * tests/aclocal.m4: Remove, as it is no longer used.
14119 2001-11-13 Akim Demaille <akim@epita.fr>
14121 * lib/autotest/general.m4: Change `tests?' into `groups?' in
14122 variable names when referring to a single test group, or to
14123 `suite' when referring to the whole test suite.
14124 `at_last_test' is removed: m4 compute at_format itself.
14125 (at_stdout, at_stder1, at_stderr): New variables.
14126 (AT_CHECK): Use them.
14128 2001-11-13 Akim Demaille <akim@epita.fr>
14130 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
14131 in PATH.
14132 Create `testsuite.dir/003/run' instead of `testsuite.003'.
14133 Do it as soon as a test fails, don't wait till the end of the test
14134 suite.
14135 Don't remove $as_me.[0-9]*, since these files no longer exist.
14137 2001-11-13 Akim Demaille <akim@epita.fr>
14139 * tests/tools.at: Use absolute paths, since we are no longer run
14140 in place.
14142 2001-11-13 Akim Demaille <akim@epita.fr>
14144 Now that tests are running in their own private dir, there is no
14145 need to list the files to remove at the end of tests groups.
14147 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
14148 (AT_data_files, at_data_files): Remove.
14149 (AT_CLEANUP, AT_DATA): Simplify.
14150 (AT_INIT): Adjust.
14151 Remove the group dir if !debug && !failed.
14152 * tests/atspecific.m4: Adjust.
14154 2001-11-13 Akim Demaille <akim@epita.fr>
14156 Start a new layout for Autotest: `testsuite' creates
14157 `testsuite.dir' in which the at-check-line etc. files are to be
14158 found, and `testsuite.dir/003' where the test group 3 is run.
14160 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
14161 at_check_line_file, at_format, at_test_normalized, at_group_dir
14162 are new variables.
14163 Create the directories.
14164 Use absolute paths for at- files.
14165 (AT_CHECK): Adjust.
14167 2001-11-11 Michael Matz <matz@kde.org>
14169 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
14170 (m4_car2): New.
14171 (m4_car): Properly quote arguments.
14173 2001-11-13 Akim Demaille <akim@epita.fr>
14175 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
14176 with stricter rules on LIBOBJS.
14178 2001-11-12 Paul Eggert <eggert@twinsun.com>
14180 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
14181 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
14182 __PROTOTYPES too.
14184 2001-11-12 Akim Demaille <akim@epita.fr>
14186 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
14188 2001-11-12 Akim Demaille <akim@epita.fr>
14190 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
14191 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
14192 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14193 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
14194 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
14195 specify to what the macro should be defined (typically to 1).
14197 2001-11-12 Akim Demaille <akim@epita.fr>
14199 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
14200 From Jim Meyering.
14202 2001-11-12 Akim Demaille <akim@epita.fr>
14204 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14205 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
14206 definition used by Automake where LEX is +/- "${missing} lex" and
14207 `missing' itself contains variables.
14209 2001-11-12 Akim Demaille <akim@epita.fr>
14211 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
14212 Now that M4sh pushes BODY, the comments were output at the end of
14213 the test suites.
14215 2001-11-08 Akim Demaille <akim@epita.fr>
14217 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
14218 that we can trace macros from aclocal.m4.
14219 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
14220 obsoleted, and redirect to the former anyway.
14221 Reported by Ralf Corsepius.
14223 2001-11-08 Akim Demaille <akim@epita.fr>
14225 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
14226 processed only if present.
14227 * tests/torture.at (Configuring subdirectories): Use autoreconf
14228 instead of successive calls to autoconf.
14229 Add a nonexistent subdirectory to exercise the patch above.
14230 Reported by Ralf Corsepius.
14232 2001-11-08 Kevin Ryde <user42@zip.com.au>
14234 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
14235 doesn't accept .S files.
14237 2001-11-07 Akim Demaille <akim@epita.fr>
14239 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

14241 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
14242 * bin/autom4te.in (warn_forbidden): New.
14243 (handle_output): Use it.
14244 Read m4_pattern_forbid with messages.
14246 2001-11-05 Akim Demaille <akim@epita.fr>
14248 * bin/autom4te.in (--normalize): Remove.
14249 * lib/autom4te.in: Adjust.
14251 2001-11-05 Akim Demaille <akim@epita.fr>
14253 * tests/Makefile.am (testsuite): Rename this target as...
14254 ($(TESTSUITE)): this.
14255 From Nicolas Joly.
14257 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
14259 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
14260 the --prefix option, also remove it's argument.
14262 2001-11-05 Akim Demaille <akim@epita.fr>
14264 * doc/autoconf.texi (testsuite Invocation): Update.
14265 (Writing testsuite.at): Update.
14267 2001-11-03 Akim Demaille <akim@epita.fr>
14269 * doc/autoconf.texi: s/@code/@command/ where appropriate.
14271 2001-11-03 Akim Demaille <akim@epita.fr>
14273 * lib/Autom4te/General.pm: (&catfile, &canonfile)
14274 (&file_name_is_absolute): New, wrappers around routines from
14275 File::Spec.
14276 Use and export them.
14277 (&find_configure_ac): Optionally take a directory where to look at.
14278 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
14279 the arguments.
14280 Default @ARGV to `.', not find_configure_ac.
14281 (&autoreconf): Argument is a directory.
14282 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
14283 * doc/autoconf.texi (autoreconf Invocation): Update.
14285 2001-11-03 Akim Demaille <akim@epita.fr>
14287 * lib/Autom4te/General.pm (@export_vars, @export_subs)
14288 (@export_forward_subs): New.
14289 Add basename, dirname, and fileparse.
14290 (@EXPORT): Adjust.
14291 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
14292 Don't look for aclocal flags if we already know aclocal is not
14293 used.
14294 Move aclocal.m4t only if it exists.
14295 Reported by Ezra Peisach.
14297 2001-11-03 Akim Demaille <akim@epita.fr>
14299 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
14300 passed on command line, defaulting to ./configure.ac if present.
14301 (&maybe_autoreconf, File::Find): Remove, unused.
14302 (&autoreconf): If autoconf is not used, don't try to trace.
14304 2001-11-02 Akim Demaille <akim@epita.fr>
14306 * configure.ac: Bump to 2.52g.
14308 2001-11-02 Akim Demaille <akim@epita.fr>
14310 Version 2.52f.
14312 2001-11-02 Akim Demaille <akim@epita.fr>
14314 * config/config.guess, config/config.sub, doc/standards.texi:
14315 * config/lispdir.m4: Update from masters.
14316 * configure.ac: Bump to 2.52f.
14318 2001-11-02 Akim Demaille <akim@epita.fr>
14320 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
14321 Don't run aclocal when aclocal.m4 is not from aclocal.
14322 From Ezra Peisach.
14323 Don't run libtoolize and gettextize if --install is not given.
14325 2001-11-01 Paul Eggert <eggert@twinsun.com>
14327 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
14328 be invoked before _AS_LINENO_PREPARE.
14329 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
14330 than character ranges.
14332 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
14333 invoking AS_BASENAME. Set the locale variables to 'C' if
14334 possible, as POSIX requires this to get the traditional
14335 behavior.
14336 * doc/autoconf.texi (Special Shell Variables): Describe the above.
14338 2001-10-31 Paul Eggert <eggert@twinsun.com>
14340 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
14341 with {}, as that triggers a bug in Bash 2.05.
14343 (_AS_LINENO_PREPARE): Use Sed rather than
14344 Awk. Fix the sed prepass to work even if there are multiple
14345 instances of $LINENO on the same line. Do not substitute for
14346 other variables like $LINENOT. Do not check file dates; such a
14347 check is unreliable on sufficiently fast machines, and removing
14348 the check makes the code simpler and more reliable. Check for
14349 output and chmod failures.
14351 * doc/autoconf.texi (Special Shell Variables): Document
14352 the above.
14354 2001-10-31 Akim Demaille <akim@epita.fr>
14356 * tests/Makefile.am (atconfig): Remove this target, Automake
14357 handles it now.
14359 2001-10-31 Akim Demaille <akim@epita.fr>
14361 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
14362 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
14363 provided, while it is optional.
14364 * configure.ac: Adjust.
14366 2001-10-26 Paul Eggert <eggert@twinsun.com>
14368 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
14369 lib/Autom4te/Struct.pm:
14370 Require Perl 5.005_03 instead of just 5.005, as some tests fail
14371 with 5.005_02.
14373 * doc/autoconf.texi (Special Shell Variables): Document some
14374 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
14376 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
14377 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
14378 eval $LINENO is not portable in practice.
14380 2001-10-24 Akim Demaille <akim@epita.fr>
14382 * lib/Autom4te/General.pm (backname): New.
14384 2001-10-24 Akim Demaille <akim@epita.fr>
14386 * m4/: Remove, merged into...
14387 * config/: here.
14389 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
14391 * doc/autoconf.texi (Shellology): Mention the problems with bash
14392 2.05's use of ANSI quoting in its `set' builtin.
14394 2001-10-22 Paul Eggert <eggert@twinsun.com>
14396 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
14397 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
14398 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
14399 POSIX decided to standardize on the int flavor of strerror_r.
14400 Always do char* test, as there's no reason not to.
14401 Assign to a char* var, to catch strerror_r that returns int*.
14403 * doc/autoconf.texi (Particular Functions):
14404 Document the above changes. Also, document the fact that
14405 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
14407 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
14409 2001-10-20 Akim Demaille <akim@epita.fr>
14411 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
14412 the executable was missing from the log.

14416 * lib/Autom4te/General.pm (&update_file): If destination is
14417 unchanged, remove the source.
14418 (&up_to_date_p): Don't be verbose, be debug.
14419 * bin/autoreconf.in: No longer support --m4dir.
14420 (&autoreconf): Display the full path of the configure.ac we are
14421 studying.
14422 Trace it only once.
14423 Be sure to honor --force with gettextize.
14424 Always run aclocal.
14425 * doc/autoconf.texi: Adjust.
14427 2001-10-20 Akim Demaille <akim@epita.fr>
14429 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
14430 Remove, dead.
14431 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
14432 `intl' is already present, as it refuses unless --force.
14433 (&parse_args): Use -I, --include instead of the old Autoconf
14434 options.
14435 ($localdir, $autoconf_dir): Remove.
14436 (@include): New.
14437 (&maybe_autoreconf): New, to preserve $_ for File::Find.
14439 2001-10-19 Jens Petersen <petersen@redhat.com>
14441 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

14447 file in @configure_input@.
14448 Don't mention `automatically' in addition to `generated'.
14449 * tests/torture.at (#define header templates): Adjust.
14451 2001-10-19 Akim Demaille <akim@epita.fr>
14453 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
14454 comment, explain how to install automatic mode selection.
14455 From Russ Allbery.
14457 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
14459 * bin/autoreconf.in (autoreconf): Display the path to the
14460 configure.ac being studied.
14462 2001-10-18 Paul Eggert <eggert@twinsun.com>
14464 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
14465 long, to work around a bug in the HP C compiler version HP92453-01
14466 B.11.11.23709.GP.
14468 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
14469 (AS_BASENAME_EXPR): New macro.
14470 (AS_BASENAME_SED): Do not assume GNU sed semantics.
14471 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
14472 and fall back on 'sed' only if the other two fail. This makes
14473 AS_BASENAME act more like AS_DIRNAME.
14474 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
14475 contains white space.
14476 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
14477 Use AS_DIRNAME, since I think it's now DOS-friendly.
14478 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
14479 Allow "dirname //FOO" to return either / or //, as POSIX allows
14480 either behavior.
14482 2001-10-10 Akim Demaille <akim@epita.fr>
14484 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
14485 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
14486 From Eric Sharkey.
14488 2001-10-10 Akim Demaille <akim@epita.fr>
14490 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
14491 m4_define, since...

14530 bother with $force since...
14531 * lib/Autom4te/General.pm: does.
14533 2001-10-08 Akim Demaille <akim@epita.fr>
14535 * bin/autoreconf.in: Rewrite in Perl.
14536 * configure.ac: Adjust.

14609 * tests/tools.at (AT_DATA_FORBIDDEN): New.

14620 empty, and if we can find a shell that does support LINENO,
14621 then set CONFIG_SHELL to that shell and then re-execute
14622 ourselves with CONFIG_SHELL.
14624 2001-10-05 Paul Eggert <eggert@twinsun.com>
14626 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
14627 doesn't exist. Remove *.tmp, as a .tmp file is created during the
14628 build of $(TESTSUITE).
14630 2001-10-05 Akim Demaille <akim@epita.fr>
14632 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

14674 instead of exec'ing to preserve $0 and $@.
14676 2001-10-01 Akim Demaille <akim@epita.fr>
14678 * tests/testsuite (AT_INIT) <at_pass_list>: New.

14697 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
14698 Don't use nested parenthesization. This patch was originally
14699 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
14700 but somehow it didn't get incorporated then.
14701 * doc/autoconf.texi (Limitations of Usual Tools):
14702 Clarify remark about sed and nested parenthesization.
14704 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
14705 Report an error if the size cannot be determined even though
14706 the type exists.
14707 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14708 Check for `expr' arithmetic overflow, and for compilation failure,
14709 and invoke a new argument $4 if either is discovered.
14710 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
14711 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
14713 2001-09-28 Akim Demaille <akim@epita.fr>

14741 * tests/c.at (Extensions, C keywords)
14742 (Broken/missing compilers, AC_PROG_CPP with warnings)
14743 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
14744 (AC_PROG_CPP requires AC_PROG_CC): here and...
14745 * tests/fortran.at (GNU Fortran 77): there.
14746 * doc/autoconf.texi (autoconf Invocation): Fix the example:
14747 AC_TRY_RUN is about compilation, not shell commands.

14753 Raja R Harinath:
14754 Be sure to detect when $LINENO always returns the same value.
14755 Look for the original script, basename($0) is certainly not
14756 enough.

14807 * doc/autoconf.texi (Common Shell Constructs): Rename as...
14808 (Programming in M4sh): this.

14852 * tests/Makefile.am (package.m4): Remove.
14854 2001-09-22 Akim Demaille <akim@epita.fr>
14856 Rely on `$LINENO' when possible instead of `__oline__'.
14858 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
14859 `$LINENO' support replacement when not supported.
14860 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
14861 them explicitly to be sure they are not output before this section
14862 (via m4_require). Cosmetic only.
14863 * lib/autoconf/c.m4, lib/autoconf/general.m4,
14864 * lib/autoconf/programs.m4: Replace all the occurrences of

14870 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
14871 character (u: -> ue) in a code comment.
14872 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
14873 it works.
14875 2001-09-21 Akim Demaille <akim@epita.fr>
14877 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
14878 Suggested by Jim Meyering.
14880 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14882 * lib/autoconf/programs.m4: Use extensions listed in
14883 $ac_executable_extensions when looking for programs.

14887 * lib/autoconf/general.m4: Fix a small Englisho.

14890 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14892 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14895 PATH_SEPARATOR.
14896 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

14899 * lib/autotest/general.m4: Replace occurrences of ':' in
14900 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
14902 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14904 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14905 arguments. Fixed a typo.
14907 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14909 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

14912 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14914 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14915 * bin/autoupdate.in: Ditto.
14916 * bin/autoheader.in: Reworded a few comments.
14917 * bin/autoconf.in: Reworded help text for a few options.

14921 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14923 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14924 already have $file). Set output files to binary mode (helps avoid
14925 CR issues on DOSish systems).
14927 2001-09-19 Akim Demaille <akim@epita.fr>
14929 * lib/autotest/general.m4: Englishoes.
14930 From Tim Van Holder and Alexey Mahotkin.
14932 2001-09-18 Paul Eggert <eggert@twinsun.com>
14934 * doc/autoconf.texi (Common Shell Constructs): New node,
14935 documenting AS_DIRNAME.
14936 (Limitations of Usual Tools): Refer to it when discussing dirname.
14937 Also, update discussion of POSIX standard to reflect latest draft.
14939 * lib/autoconf/c.m4:
14940 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14942 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14943 Do not pass a first argument with leading '-'
14944 to expr, by parenthesizing initial integers that might be negative.
14946 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14947 now merely checks whether it is an error to pass an argument
14948 to getpgrp.
14950 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14951 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14952 whether it is a (compile-time) error to pass an argument to
14953 getpgrp. This simpler test supports the revised documentation,
14954 and is all that AC_FUNC_GETPGRP's users really need.
14956 2001-09-18 Akim Demaille <akim@epita.fr>
14958 * doc/autoconf.texi (Limitations of Make) <$<>: New.
14960 2001-09-18 Akim Demaille <akim@epita.fr>

14968 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14969 correctly.
14970 Add test for AS_BASENAME.
14971 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14972 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14973 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14974 * tests/base.at: Fixed the expected responses. The old ones were
14975 one line out...
14976 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14977 the documentation claims it should (and how it behaved in 2.13).
14979 2001-09-18 Akim Demaille <akim@epita.fr>
14981 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14982 the AC_CONFIG_COMMANDS invocation.
14983 This also solves the name clash problems.
14984 Don't set the package's ID.
14985 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14986 No longer to be shipped.
14987 (version.in): Remove.
14988 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14989 * lib/autoconf/status.m4: Adjust.
14990 Use `m4_PACKAGE_STRING'.
14991 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14992 the only optional argument is the name of the test suite.
14993 Expect `package.m4' to define the package signature.
14994 * lib/autom4te.in (Autotest): Add `package.m4?'.
14995 * tests/Makefile.am (package.m4): New.
14996 * tests/suite.at: ifnames is a victim.
14998 2001-09-18 Akim Demaille <akim@epita.fr>
15000 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
15001 AC_LIBSOURCE, AC_CONFIG_FILES.
15002 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
15003 program version string doesn't match the package's.
15004 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
15005 after `(cached)'.

15009 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15010 Allow expression to return any value that can fit into unsigned long
15011 (not int, as before). Check for output errors.
15013 2001-09-17 Bruno Haible <haible@ilog.fr>
15015 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
15016 Always include <stdio.h> and <stdlib.h>. Evaluate
15017 the expression in an extra function before these includes. Call
15018 fprintf "%d" only after ensuring the argument is of type 'int'.
15019 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
15021 2001-09-17 Paul Eggert <eggert@twinsun.com>
15023 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
15024 or CFLAGS=-O5. In that case, the linker has a relaxed view of
15025 fatal errors, and AC_CHECK_LIB causes it to include libraries even
15026 when they don't exist.
15028 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
15029 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
15030 need it.
15032 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
15033 version with the version used by fileutils 4.1, except use
15034 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
15035 we don't need it.
15037 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
15039 2001-09-13 Akim Demaille <akim@epita.fr>
15041 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
15042 _first_.
15043 Reported by Gerrit P. Haase.
15045 2001-09-13 Akim Demaille <akim@epita.fr>
15047 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
15048 m4_defn'ing is valid.

15062 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
15063 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
15064 Likewise.

15067 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
15068 AT_tests_all for consistency.

15070 (AT_VICTIMS): Similar to AT_KEYWORDS.
15071 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
15073 2001-09-13 Akim Demaille <akim@epita.fr>
15075 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
15077 2001-09-13 Akim Demaille <akim@epita.fr>
15079 * lib/autotest/general.m4 (AT_INIT): Create and remove
15080 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
15081 test suites can cohabit.
15083 2001-09-13 Akim Demaille <akim@epita.fr>
15085 * tests/mktests.sh: Don't output banners for empty test files.
15087 2001-09-13 Akim Demaille <akim@epita.fr>
15089 Test suites can be run independently of configure.

15104 (Syntax of the shell scripts): Don't check ifnames.
15105 (AT_CHECK_PERL_SYNTAX): New.

15130 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
15131 (m4_list_append): Remove.
15133 Spread a few keywords in the Autoconf test suite.
15135 2001-09-10 Akim Demaille <akim@epita.fr>
15137 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

15153 2001-09-07 Akim Demaille <akim@epita.fr>
15155 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
15156 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
15157 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
15158 related variables into `at_package_*'.

15168 Move toward possibly stand-alone test suites.
15170 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
15171 in addition, it introduces useless differences in logs.
15172 (AT_INIT): Let atconfig and atlocal be both optional.
15173 Adjust PATH computation.
15174 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

15178 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

15181 2001-09-05 Akim Demaille <akim@epita.fr>
15183 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
15184 to avoid GCC warnings.
15185 From Uwe Seimet.
15187 2001-09-05 Akim Demaille <akim@epita.fr>
15189 * bin/autom4te.in: --language is -l, not -s.
15191 2001-09-05 Akim Demaille <akim@epita.fr>
15193 Be ready to handle filenames as stupid as `dnl.at', for if even
15194 the maintainer is dumb enough to do that...
15196 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
15197 excellence in M4 quotation: consider `__file__' is active.
15199 And BTW, when invoking m4, pass the --include in the right order:
15200 the wrong one.
15202 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
15203 4m.
15205 2001-09-05 Akim Demaille <akim@epita.fr>
15207 * lib/Autom4te/XFile.pm: New lib file.
15208 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
15209 * bin/autoheader.in: Use it.
15211 2001-09-05 Akim Demaille <akim@epita.fr>
15213 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
15214 defined.

15221 * bin/autoscan.in: Use `getopt' and `find_files' etc.
15222 Add -I, --include support.
15223 * doc/autoconf.texi (autoscan Invocation): Adjust.
15225 2001-09-05 Akim Demaille <akim@epita.fr>
15227 CVS GNU M4 doesn't like `undefine(undefined)'.
15229 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
15230 New, extracted from main.
15231 Use IO::File wherever possible.
15232 (input.m4): Be constant, use -I instead of hard coding $tmp.
15233 Therefore be a quoted heredoc.
15234 Don't invoke `_au_disable', since ac was not loaded, but just
15235 `unm4.m4'.
15237 2001-08-31 Akim Demaille <akim@epita.fr>
15239 Version 2.52d.
15241 2001-08-31 Akim Demaille <akim@epita.fr>
15243 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
15244 previous patch.
15245 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
15247 2001-08-31 Akim Demaille <akim@epita.fr>
15249 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
15250 serious problems handling heredocs in heredocs.
15251 Reported by Nicolas Joly.
15253 2001-08-31 Akim Demaille <akim@epita.fr>
15255 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
15256 (Making testsuite Scripts): Update.
15258 2001-08-31 Akim Demaille <akim@epita.fr>
15260 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
15262 2001-08-31 Akim Demaille <akim@epita.fr>
15264 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
15265 (testsuite Scripts): There is no such thing as `atconfig.in'.
15266 And actually one diagram is missing: test suite runtime.
15268 2001-08-31 Akim Demaille <akim@epita.fr>
15270 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
15271 inverse order.
15273 2001-08-31 Akim Demaille <akim@epita.fr>
15275 * bin/autoupdate.in (@include): `installcheck' revealed the path
15276 to m4sugar was lacking!
15278 2001-08-31 Akim Demaille <akim@epita.fr>
15280 * man/Makefile.am (.x.1): We really have to pass
15281 autom4te_perllibdir.
15283 2001-08-31 Akim Demaille <akim@epita.fr>
15285 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
15286 debug scripts, in particular passing explicitly listed tests to
15287 run is stupid.
15289 2001-08-31 Akim Demaille <akim@epita.fr>
15291 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
15292 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
15293 Use directly autom4te, not autoconf.
15294 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
15296 2001-08-31 Akim Demaille <akim@epita.fr>
15298 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
15299 * bin/autoheader.in (%symbol): Strip arguments of macros.

15305 2001-08-31 Akim Demaille <akim@epita.fr>
15307 * bin/autom4te.in (&parse_args): Die on unknown languages.
15308 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
15309 need for autoconf.
15310 Promote --include over --macrodir and other obsolete options.
15312 2001-08-31 Akim Demaille <akim@epita.fr>
15314 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
15315 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
15316 * bin/autom4te.in ($autoconf): Pass --force.
15317 `print $out' doesn't print `$_' but `$out'.
15318 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
15319 (autoheader): Pass --force since the test suite goes too fast for
15320 the time stamps.
15321 Adjust to the new autoheader messages.
15323 2001-08-31 Akim Demaille <akim@epita.fr>
15325 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
15326 Check the completeness of the #template.
15327 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
15328 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
15329 invocation.
15331 2001-08-31 Akim Demaille <akim@epita.fr>
15333 * lib/Autom4te/General.pm (&find_file, &update_file): New.
15334 * bin/autoupdate.in, bin/autoheader.in: Adjust.
15335 Drop AC_MACRODIR dead for real.
15336 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
15337 `autoheader: `config.hin' is created'.
15338 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
15340 2001-08-31 Akim Demaille <akim@epita.fr>
15342 * bin/autoheader.in: Rewrite in Perl.
15343 * tests/autoheader: Adjust.
15345 2001-08-31 Akim Demaille <akim@epita.fr>
15347 * bin/autoconf.in (--include, -I): New option.
15348 Map --localdir, --autoconf-dir onto it.
15349 Forward autom4te's options instead of interpreting them.
15350 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
15351 There is no such envvar since the inception of autom4te.cfg.
15352 * bin/autom4te.in (&parse_args): Uniquify `@include'.
15353 * bin/autoupdate.in: Adjust, and perform more control.
15354 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
15355 * tests/autoconf: Dittowise.
15357 2001-08-31 Akim Demaille <akim@epita.fr>
15359 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
15360 * bin/autom4te.in (&find_file): Support `FILE?' standing for
15361 optionally `FILE'.
15362 Use -e, not -f, since /dev/null for instance is OK.
15363 (&parse_args): Adjust.
15364 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
15366 2001-08-31 Akim Demaille <akim@epita.fr>
15368 * configure.ac: Also find tested executables in bin.
15369 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
15370 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
15371 installed peer executables, only PATH is allowed to resolve it.
15372 Pass `autoconf_dir' via options, not via invisible envvars.
15373 * lib/Autom4te/General.pm (&find_peer): Remove.
15374 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
15375 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
15376 * man/Makefile.am: Let help2man rely on PATH instead of trying to
15377 find the executables for it.
15378 * tests/Makefile.am: Major cleanup. Too lazy to document...
15379 * tests/atlocal.in: Remove all the obscure envvar manipulations.
15380 We only need PERL.
15381 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
15382 indeed related to running the test suite, while passing
15383 --autoconf-dir and others is related to running non installed
15384 Autoconf executables. So don't do that, leave it to...
15385 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
15386 * tests/autoscan: New.
15387 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
15388 refer to library files: rely on --language.
15390 2001-08-29 Akim Demaille <akim@epita.fr>
15392 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
15393 s/--set/--language/.
15395 2001-08-29 Akim Demaille <akim@epita.fr>
15397 * doc/autoconf.texi: Strip the @nodes.
15398 Suggested by Paul Eggert.
15399 (Initializing configure): Typo.
15401 2001-08-29 Akim Demaille <akim@epita.fr>
15403 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
15404 Suggested by Paul Eggert.
15406 2001-08-29 Akim Demaille <akim@epita.fr>
15408 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
15409 download in a tmp dir.
15411 2001-08-29 Akim Demaille <akim@epita.fr>
15413 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
15414 case insensitive OSes out there :(
15415 From Tim Van Holder.
15417 2001-08-29 Akim Demaille <akim@epita.fr>
15419 * lib/autom4te.in: New.
15420 * lib/Makefile.am (edit, autom4te.cfg): New.
15421 * bin/autom4te.in (BEGIN): Simplify.
15422 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
15423 (&load_configuration): New. Use it.
15424 (&parse_args): Support --mode, --set, and --melt.
15425 * bin/autoconf.in: Simplify and adjust.
15426 * tests/Makefile.am (AUTOMAKE): Use --set.
15427 * tests/atlocal.in: Adjust.
15428 * BUGS: distcheck and check are weak.
15430 2001-08-29 Akim Demaille <akim@epita.fr>
15432 * lib/autotest/general.m4: Use
15433 foo=`(command) 2>/dev/null`
15434 not
15435 foo=`command` 2>/dev/null
15436 (at-devnull): Rename as...
15437 (AT-devnull): this.
15438 (--clean): Remove AT-* files too.
15439 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
15440 Reported by Nicolas Joly.
15442 2001-08-28 Akim Demaille <akim@epita.fr>
15444 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
15445 quotes inside single quotes.
15446 Reported by Nicolas Joly.
15448 2001-08-28 Kevin Ryde <user42@zip.com.au>
15450 * doc/autoconf.texi (Function Portability): Mention C right shifts.
15452 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
15454 * lib/autotest/general.m4: Reword some messages.
15455 (AT_INIT): Check for the `times' builtin before using it.
15456 Support test ranges as arguments to the testsuite.
15457 Have -e imply -d as the help text suggested.
15459 2001-08-27 Akim Demaille <akim@epita.fr>
15461 * Makefile.maint: Formatting changes.
15462 (do-po-update, po-update, cvs-update, update): New targets.
15463 (AMTAR): Remove.
15465 2001-08-27 Akim Demaille <akim@epita.fr>
15467 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

15474 * lib/autotest/general.m4 (AT_INIT): Log the command line.
15475 Support `VAR=VAL' as arguments.
15476 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
15477 may be set via the command line.
15479 2001-08-27 Akim Demaille <akim@epita.fr>
15481 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
15482 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
15483 first the build dirs, then the src dirs.

15486 2001-08-27 Akim Demaille <akim@epita.fr>
15488 * lib/autotest/general.m4 (AT_INIT): Output the definition of
15489 at_data_files earlier.

15493 2001-08-27 Akim Demaille <akim@epita.fr>
15495 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
15496 `ac_top_builddir' to mimic Automake's vocabulary, which much more
15497 readable.
15498 Adjust callers.
15499 * doc/autoconf.texi (Configuration Actions): Document the vars
15500 available in commands.
15501 Emphasize the risks of collisions in init-cmds.

15505 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
15506 (Initializing configure): this new node.
15508 2001-08-27 Akim Demaille <akim@epita.fr>

15521 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

15531 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
15532 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
15533 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
15534 -> ac_dir).
15535 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
15536 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
15538 2001-08-27 Akim Demaille <akim@epita.fr>

15563 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
15564 (AMTAR): Help automake define it.
15565 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
15566 needed, 1.5 can have a macro and a target with the same name.
15567 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
15568 * m4/strip.m4: New.

15581 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.
15582 Adjust callers.
15583 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
15584 the name of the directory they're in, instead of the filename,
15585 since version.m4 is now in m4sugar, but m4_acversion must not be
15586 classified as an Autoconf macro.
15587 ($input_m4): Don't qualify the path to m4sugar.
15588 Rather, pass autoconf_dir to m4.
15589 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
15590 * tests/suite.at: Require 2.52c.
15592 2001-08-27 Akim Demaille <akim@epita.fr>

15604 of config.log on traps.
15605 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
15606 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
15607 for config.status'.
15608 Open the log as soon as possible.
15609 Use the same log introduction as configure's.
15611 2001-08-22 Paul Eggert <eggert@twinsun.com>
15613 * doc/autoconf.texi (Indices): New node.
15614 Move indices out of the top level menu and into this submenu.
15616 2001-08-22 Akim Demaille <akim@epita.fr>
15618 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
15619 AC_TRY_COMMAND.

15673 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
15674 * NEWS, README, README-alpha, TODO, tests/README: This package is
15675 `Autoconf', not `autoconf' (the executable).
15677 2001-08-20 Akim Demaille <akim@epita.fr>
15679 Info readers seem to need `Index' in the index node title :(
15681 * doc/autoconf.texi: Reverse the 2001-08-15 change which
15682 simplified index node names.
15684 2001-08-20 Akim Demaille <akim@epita.fr>

15726 2001-08-20 Akim Demaille <akim@epita.fr>
15728 Huh!?!?! There are still some user EOF tags used, which prevents
15729 their use in AC_CONFIG_COMMANDS for instance...
15731 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
15732 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
15733 `_CSEOF', or `_ATEOF', as appropriate.

15793 2001-08-17 Akim Demaille <akim@epita.fr>
15795 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
15796 `$0.log' as for projects where testsuite is in src, we'd have
15797 testsuite.log created in src.

15811 2001-08-17 Akim Demaille <akim@epita.fr>
15813 * doc/autoconf.texi: Work around Texinfo buglets.
15814 (Transformation Rules): One example is enough, users are expected
15815 to have their brains on. And BTW, use DESTDIR.
15816 (dvar): New macro. Use it.
15818 2001-08-17 Akim Demaille <akim@epita.fr>
15820 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

15826 * bin/autom4te.in: --normalize is a new option.
15827 * bin/autoconf.in: Use it.

15839 2001-08-15 Akim Demaille <akim@epita.fr>
15841 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
15842 Use it.

15853 * doc/install.texi: Use @command.

15857 2001-08-15 Akim Demaille <akim@epita.fr>
15859 * doc/autoconf.texi (Function Portability): sprintf's return
15860 value.
15861 From Kevin Ryde.
15863 2001-08-15 Akim Demaille <akim@epita.fr>
15865 * Makefile.maint (CVS): New.
15866 (local-check): Run changelog-check. last.
15867 (alpha): Don't depend upon local-check, since...
15868 (cvs-dist): depends upon it.
15870 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
15872 * tests/Makefile.am: Use a clean-local rule to remove
15873 autom4te.cache (it's a directory, not a file.
15874 * Makefile.am: Ditto (but maintainer-clean-local).
15876 2001-08-15 Akim Demaille <akim@epita.fr>
15878 * bin/autom4te.in (@m4_warning): New.
15879 (&handle_m4): Use it.
15880 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
15881 warnings are issued at each run.
15882 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
15883 is in the src tree.
15885 2001-08-15 Akim Demaille <akim@epita.fr>
15887 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15888 don't waste time running `autoupdate --version' works.
15889 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15891 2001-08-13 Akim Demaille <akim@epita.fr>
15893 * doc/autoconf.texi (ma): Rename this index as...
15894 (ac): this.

15907 duration of the test suite.
15909 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15911 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
15912 endianness for comparison instead of relying on AT_CHECK_ENV.
15914 2001-08-11 Paul Eggert <eggert@twinsun.com>
15916 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
15917 to the INSTALL file.
15919 2001-08-11 Paul Eggert <eggert@twinsun.com>

15944 * tests/mktests.sh: Update year in copyright notice.
15946 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15948 * tests/semantics.at (AC_C_BIGENDIAN): New test.
15950 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15952 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15953 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15954 * doc/autoconf.texi (C Compiler Characteristics): Update
15955 documentation for AC_C_BIGENDIAN.
15957 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15959 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15960 magic values from an object file when cross-compiling.
15961 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15963 2001-08-10 Akim Demaille <akim@epita.fr>
15965 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15966 effects.
15967 Suggested by Russ Allbery.
15969 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15971 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15972 current $prefix to the sub-configures.
15974 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15976 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15977 extension (needed on BeOS). Reported by Guido van Rossum.
15979 2001-08-09 Akim Demaille <akim@epita.fr>
15981 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15983 2001-08-07 Akim Demaille <akim@epita.fr>
15985 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15986 removed.
15987 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15988 No need to remove the files before and after the each test, before
15989 each test and at the end of the suite is enough.
15990 Display only the children `times', not the shell's.
15991 If the test failed or was skipped, at-times is not available.
15993 2001-08-07 Akim Demaille <akim@epita.fr>
15995 Always produce testsuite.log, including when there are no
15996 failures. This helps getting information on skipped tests, and
15997 duration of the tests. Err, implement the latter btw.
15999 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
16000 Dump information on the first run of each test.
16001 (AT_CLEANUP): Create `at-times' containing the duration of the
16002 test group.
16004 2001-08-07 Akim Demaille <akim@epita.fr>
16006 The use of `dumpstat' revealed that `len' was used although it
16007 should not. m4_text_wrap was using it, but in the Autoconf world
16008 where it is legal. Hence (i) test M4sh in its own world, not
16009 Autoconf's, and (ii), ahem, fix the bug :)
16011 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
16012 does not like `' instead of [].
16013 (AT_INIT): Forbid `^_?AT_'.
16014 And don't output such tokens.
16015 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
16016 `script.as', and `autom4te.cache'.
16017 Remove `empty' and `macro' which are no longer used.
16018 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
16019 * tests/m4sugar.at: Use it.
16020 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
16022 2001-08-07 Akim Demaille <akim@epita.fr>
16024 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
16026 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
16028 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
16030 2001-08-04 Akim Demaille <akim@epita.fr>
16032 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
16033 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
16034 AC_TRY_LINK.
16035 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
16036 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
16037 (AC_F77_MAIN): Likewise.
16039 2001-08-04 Akim Demaille <akim@epita.fr>
16041 Don't rely on M4sugar outputting the patterns in files, since we
16042 might process the output _without_ running m4, hence without these
16043 files.
16045 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
16046 * bin/autom4te.in (@Request::includes): Remove, unused.
16047 (@Request::source): Rename as...
16048 (@Request::input): this.
16049 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
16050 (&handle_output): Fetch the patterns from the traces.
16051 `$forbidden' and `$allowed' are constant: use m//o.
16052 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
16053 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
16055 2001-08-04 Akim Demaille <akim@epita.fr>
16057 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
16058 autoconf', i.e., in addition to caching traces, cache the output.
16060 * bin/autom4te.in (Request::cache): Rename as...
16061 (Request::id): this.
16062 ($cache, $icache, $tcache, $ocache): New.
16063 (&handle_m4): Save M4 output in the cache instead of $tmp.
16064 (&handle_output): Adjust.
16065 (&up_to_date_p): Check that the output cache is up to date too.
16066 (top level): Run `&handle_m4' iff force or the cache is invalid.
16067 Run `&handle_output' if the output cache is more recent.
16069 2001-08-04 Akim Demaille <akim@epita.fr>
16071 * bin/autom4te.in ($force): New.
16072 (&parse_args, &print_usage): -f, --force is a new option.
16073 (&handle_output): CPP directives might have spaces after `#'.
16074 (&parse_args): The first file only can be frozen.
16076 2001-08-04 Akim Demaille <akim@epita.fr>
16078 Don't let autom4te compute the `include' traces several times:
16079 first check that the trace cache file is up to date, and then
16080 compare its timestamp with that of the output.
16082 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
16083 the preamble. Don't require 5.005 as Autom4te::General does it,
16084 and better yet (use `use', not `require'!).
16085 * lib/Autom4te/Struct.pm: Rename the last occurrences of
16086 Class::Struct as Autom4te::Struct.
16087 * lib/Autom4te/General.pm (File::stat): Use it.
16088 (&mtime): New, export it.
16089 * bin/autom4te.in: Use it.
16090 Declare `$req' is invalid if it is outdated.

16610 cross-language link tests can be performed successfully.
