151 docs: more details about make VPATH rewriting woes
152 * doc/autoconf.texi (Automatic Rule Rewriting): Solaris make
153 VPATH rewriting applies to any whitespace-separated word in a
154 rule, so it might apply also to shell variables, functions
155 and keywords (and automake has already tripped on this once);
156 document this, with an example. Since we are at it, do some
157 minor reformatting of existing text.

173 AC_C_CONST: don't reject gcc -Werror -Wall
174 * lib/autoconf/c.m4 (AC_C_CONST): Don't reject gcc when it is used
175 with -Werror -Wall during configuring. It's unwise to use GCC
176 that way, but apparently enough people do it nowadays that it's an
177 issue. These days nobody uses the old compilers that the old
178 tests reject, so we can't test this fix against them, but it's
179 more important to work with modern GCC (even when misused) than to
180 work with no-longer-used compilers. Problem reported by Shevek in
181 <http://lists.gnu.org/archive/html/bug-autoconf/2008-11/msg00007.html>

513 autoconf: tune long long tests, particularly for c99
515 This change is imported from gnulib.
516 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Don't bother compiling
517 or running anything if c99, or if unsigned long long int does not
518 work. In either case, we know the answer without further tests.
519 Do not compile _AC_TYPE_LONG_LONG_SNIPPET twice. Instead, compile
520 it at most once, and use its results for both long long int and
521 unsigned long long int. This is more likely to be efficient in
522 the common case where the program wants to check for both long
523 long int and unsigned long long int.
524 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Don't bother compiling if c99,
525 since the answer is already known.

1049 fortran: always avoid AC_LANG_CONFTEST warning
1050 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST()): Make the default

1064 New test, that $tmp is available but not essential.
1066 docs: avoid use of $tmp outside of config.status use
1067 * doc/autoconf.texi (Polymorphic Variables, Shell Substitutions):
1068 Use $var or $t instead.
1069 (Limitations of Usual Tools): Use $dir instead.
1070 (Initialization Macros) <AS_TMPDIR>: Make good on the NEWS
1071 regarding AS_TMPDIR being documented as consuming $tmp.
1072 Suggested by Ralf Wildenhues.
1074 2010-08-29 Paul Eggert <eggert@cs.ucla.edu>
1076 AC_PROG_YACC: fix comment re what "yacc" stands for

1092 Try to update config.cache atomically; respect symlinks.
1093 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use `mv -f' to update
1094 the cache file if it is a regular file and not a symlink. Move
1095 first to temporary name in the target directory if not in the
1096 current directory for atomicity across mount points.
1097 * tests/base.at (AC_CACHE_CHECK): Try symlinked cache file.
1098 * doc/autoconf.texi (Cache Files): Leftover temporary cache
1099 files may be deleted by the user.
1102 2010-08-27 Eric Blake <eblake@redhat.com>
1104 m4sh: protect LINENO against stray macro
1105 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Double quote entire
1106 sed script, to avoid issue uncovered by automake testsuite where
1107 'b' was an m4 macro that broke execution on dash.
1108 Reported by Stefano Lattarini.
1110 m4sh: assume ${a:-b} support
1111 * tests/m4sh.at (Null variable substitution): New test.

1145 Reported by Ralf Wildenhues.
1147 docs: mention another issue with variable expansion
1148 In particular, see http://austingroupbugs.net/view.php?id=221

1152 <${var=literal}>: Tweak wording. Add mention of an ambiguity
1154 * tests/torture.at (Substitute and define special characters):
1155 Make test more robust; here, the outer "" is in a here-doc, and
1156 does not violate the quoting rules of thumb just documented.

1168 m4sh: reduce size of AS_VAR_TEST_SET
1169 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Make more compact.
1171 tests: improve some shell assumption testing

1205 Report from Rainer Tammer.
1207 2010-08-24 Paul Eggert <eggert@cs.ucla.edu>
1209 AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
1210 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
1211 &s;" test into the main program, as C99 might plausibly be
1212 interpreted as not requiring support for this construction in
1213 static initializers. Remove the "#if defined __xlc__" stuff, as
1214 the bug is not present in recent xlc implementations, and they
1215 reject the test for other (valid) reasons. People using ancient
1216 xlc versions, if any, are suggested to update to fixed versions.

1231 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Drop gcc (and by
1232 extension clang) check in favor of a gnulib test. Force failure,
1233 rather than merely testing for a compiler extension.
1235 Reported by Anders Kaseorg.
1237 2010-08-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2849 Work around DJGPP shell function return bug with command substitutions.
2850 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
2851 shell function which also contains a command substitution causes
2852 the shell to barf. For more details and a fix see:
2853 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>

2883 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
2884 and both `conftest' and `conftest.exe' with `-o conftest', but not

7959 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
7960 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7961 (m4_require): Use m4_do, not m4_join.
7963 Fix some whitespace tests on cygwin.
7964 * tests/tools.at (autom4te and whitespace in file names): Restore
7965 font-lock. Create $TMPDIR before it might be used.
7967 Fix spurious testsuite failure with M4 1.4.11.
7968 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
7970 Optimize AC_REQUIRE.
7971 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
7972 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7973 (m4_require): Avoid extra macro calls.
7975 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7977 * tests/torture.at (srcdir): Fix quoting.
7979 Do not pass top_srcdir to configure scripts in testsuite.
7980 * tests/autotest.at (srcdir propagation): Copy install-sh to
7982 (my only test): Drop setting of `top_srcdir'.
7983 * tests/base.at (Input/Output): Likewise.
7984 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
7985 config.guess, and config.sub to test source tree.
7986 Drop AC_CONFIG_AUX_DIR setting.
7987 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
7988 * tests/torture.at (Substitute a 2000-byte string): Drop
7989 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
7990 (Substitute a newline, datarootdir workaround): Likewise.
7991 (Define a newline): Adjust for linenumber changes in configure.ac.
7992 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
7994 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
7995 if `pwd` contains whitespace.
7997 Quote $abs_top_srcdir in tests.
7998 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
7999 * tests/tools.at (Syntax of the shell scripts): Likewise.
8001 * tests/m4sh.at (LINENO): Quote $0.
8003 Fix testsuite program wrapper for whitespace in `pwd`.
8004 The problem here is that the usual mantra is that command
8005 variables can contain arguments, thus we cannot just escape
8006 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
8007 $top_builddir/tests directory early in $PATH, so that the
8008 wrappers are found by their plain name.
8009 * tests/wrapper.as: Put $testdir early in $PATH.
8010 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
8012 Proper config.status --file/--header and $srcdir escaping.
8013 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
8014 characters in $ac_file_inputs.
8015 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
8017 * tests/torture.at (datarootdir workaround): Adjust.
8018 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
8020 Fix Autotest for whitespace in `pwd`.
8021 * lib/autotest/general.m4 (AT_INIT)
8022 <at_func_create_debugging_script, Driver Loop>:
8023 Quote $at_group_dir.
8024 * tests/autotest.at (whitespace in absolute testdir): New test.
8026 * lib/autom4te.in: Quote @datadir@.
8028 Proper file name escaping in Autoconf programs and Perl modules.
8029 This includes escaping of characters special to the shell
8030 as well as special to Perl, e.g., leading `<' or `>'.
8031 For example, when $file starts with `>', `open ">$file"'
8032 wrongly tries to append to a different file.
8033 * bin/autoconf.as: Fix quoting for autom4te options.
8034 * lib/Autom4te/General.pm (shell_quote): New function, taken
8035 from coreutils, written by Jim Meyering.
8037 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
8039 * bin/autoreconf.in (parse_args): Likewise.
8040 * bin/autoscan.in (main): Likewise.
8041 * bin/autoupdate.in (main): Likewise.
8042 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
8043 * bin/ifnames.in: Likewise, XFile usage fixes.
8044 * tests/tools.at (autom4te and whitespace in file names): Extend
8045 test. Test twice, with special characters allowed on w32, and the
8046 rest. Test leading and trailing whitespace, for `open_quote'.
8047 (autotools and whitespace in file names): New, analogous test.
8048 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
8049 by Russ Allbery and Eric Blake.
8052 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
8053 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
8054 * lib/Autom4te/FileUtils.pm (open_quote): New function.
8055 (update_file, contents): Use it.
8057 * Makefile.am (autom4te-update): Rewrite for git.
8059 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8061 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
8063 Fix copyright years.
8064 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
8065 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
8067 2007-12-04 Eric Blake <ebb9@byu.net>
8069 Manually resync with gnulib, since 'make cvs-update' no longer works.
8070 * build-aux/config.guess: New upstream version.
8071 * build-aux/config.sub: Likewise.
8073 When using older automake, don't downgrade build-aux/texinfo.tex.
8074 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
8075 * doc/Makefile.am (TEXINFO_TEX): Add.
8077 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
8079 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
8080 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
8081 #undef as this runs afoul of our new way of creating config.h.
8082 Problem reported by Jim Meyering in
8083 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
8085 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8087 Fix autom4te for unusual characters in input file names.
8088 * bin/autom4te.in (files_to_options): Quote active characters
8090 * tests/tools.at (autom4te and white space in file names):
8093 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
8094 Document that Tru64 awk always splits $0.
8096 2007-11-24 Stepan Kasal <kasal@ucw.cz>
8098 * lib/autotest/general.m4 (AT_INIT): Do not extract the
8099 `#AT_STOP_...' line at the end of each test.
8101 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8103 * lib/autotest/general.m4 (AT_INIT): For awk line number
8104 extraction script, ensure `$at_group' has a defined value
8105 even for the empty set, and properly quote its usage inside
8108 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8110 * doc/autoconf.texi (Shell Functions): New chapter. Document
8111 IRIX sh $0 issue in functions, move content from ...
8112 (Portable Shell): ... here.
8113 (Shell Script Compiler): Note that shell functions are not
8114 totally unportable any more.
8116 2007-11-22 Stepan Kasal <kasal@ucw.cz>
8117 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8119 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
8120 extracting the line numbers of the last needed test.
8122 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8124 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
8127 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8129 Fix IRIX testsuite debugging failures: $0 in functions.
8130 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
8131 Do not use $0 inside a function, as IRIX sh will set that to the
8132 function name rather than the script invocation name.
8134 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
8135 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8137 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
8138 to extract test scripts.
8139 (AT_INIT): Extract and cache test script line numbers.
8141 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8143 * lib/autotest/general.m4: Revert 2007-11-15 patch and
8144 subsequent fixups; the awk -> here-document conversion trashes
8145 performance too much with AIX sh.
8147 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8149 * tests/local.at: Do not test m4, perl with AT_TESTED.
8151 Diagnose and guard against write errors dealing with config.status.
8152 The general idea is this: all write failures from `configure'
8153 writing `config.status' are indicated by $ac_write_error, which
8154 is only checked at the end. This is safe because config.status
8155 code is not executed before the file is complete. Other write
8156 failures, be they inside config.status, or in sub shell/awk
8157 scripts spawned from configure or config.status, typically need
8158 earlier checking, as their results are used right afterwards.
8159 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
8160 before writing config.status, check afterwards.
8161 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
8162 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
8163 Set `ac_write_error' for write failures to config.status. Barf
8164 upon write failures to temporary files.
8165 Adjust note about closing and reopening the here-document.
8166 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
8167 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
8168 reopening the here-document.
8169 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8170 Ensure `ac_write_error' does not escape into config.status.
8171 Also, add a couple of code paths not yet exercised in the test
8172 suite: a config file with input from stdin, and a config header
8174 Suggestion for catching write errors by Bruno Haible.
8176 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8178 Avoid error with Tru64 awk and testsuite lines with many words.
8179 * lib/autotest/general.m4 (AT_INIT): In the awk script that
8180 reads the testsuite, set the field separator to an unusual value,
8181 in order to not run over the limit of 199 fields. Tru64 4.0D awk
8182 even splits the input if $i, i>0, was never accessed in the script.
8184 Revert 2007-10-17 change.
8185 * TODO: Multiline args in config files and headers mean something
8186 different and are not fixed, see
8187 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
8188 Report by Stepan Kasal.
8190 * doc/autoconf.texi (Generic Programs): Fix typo.
8192 2007-11-16 Stepan Kasal <kasal@ucw.cz>
8194 AC_*_TOOL does not canonicalize the prefix
8195 * doc/autoconf.texi (Generic Programs): Do not say that
8196 the *_TOOL macros canonicalize, they simply use the `host_alias'.
8198 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8200 Diagnose write errors in config.status instantiations.
8201 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
8202 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
8204 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
8205 Extend test to also check for some write error failures, using...
8206 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
8207 Report by Bruno Haible.
8210 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
8212 (_AT_CHECK): Use less indentation, to save space.
8214 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8216 Add witness macro for @top_build_prefix@ substitution.
8217 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
8218 (_AC_OUTPUT_FILE): Mention it here.
8220 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
8221 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8223 * lib/autotest/general.m4 (at_func_test): Remove.
8224 (AT_INIT): Pre-extract test groups into separate files.
8225 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
8226 Remove at-test-source files together with the $at_group_dir.
8227 * tests/autotest.at (Long test source lines): New test.
8229 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8231 Shell functions and variables may share a namespace.
8232 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
8235 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
8237 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
8240 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8242 * lib/autoconf/status.m4: Fix a couple of comment typos.
8244 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
8246 2007-11-13 Jim Meyering <meyering@redhat.com>
8248 Clean up the rule to create "expr".
8249 * tests/Makefile.am (expr): Don't redirect directly to target.
8250 Redirect just once, not for each echo statement.
8251 Use $@, not literal "expr".
8253 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
8255 Don't worry about preprocessor when testing long long.
8256 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
8257 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
8258 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
8259 These no longer check for preprocessor flaws.
8260 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
8261 Do not check for preprocessor flaws.
8263 2007-11-13 Jim Meyering <meyering@redhat.com>
8265 Adapt dependencies, now that a version change doesn't modify configure.ac
8266 * GNUmakefile: Remove "make clean" kludge.
8267 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
8269 Don't redirect directly to target.
8270 Use $@, not literal "version.m4".
8272 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8274 * doc/autoconf.texi (Making testsuite Scripts): Document
8275 ":;{" shorthand as in previous patch.
8277 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
8279 * doc/autoconf.texi (Limitations of Builtins): Document problem
8280 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
8282 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
8283 Use ":;{" shorthand.
8284 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
8286 2007-11-12 Jim Meyering <meyering@redhat.com>
8288 Add more non-srcdir build support.
8289 * GNUmakefile (dummy): Split a long line.
8290 Add -v option to autoreconf invocation.
8292 Remove the autoreconf-provided INSTALL, so that we regenerate it.
8293 * GNUmakefile (dummy): Remove INSTALL.
8295 Remove racy commands to build scripts in bin/ and tests/.
8296 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
8297 are guaranteed to be built, remove the rules that tried to build
8298 them. Before, with a parallel build, these rules could lead to
8299 two processes writing tests/wrapper.in concurrently.
8301 Build in man/ only *after* building in bin/ and tests/.
8302 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
8303 in both bin/ and tests/.
8305 Accommodate non-srcdir build-from-checkout.
8306 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
8307 Use git's --git-dir=$srcdir/.git option.
8308 Add quotes, in case tarball_version_file contains shell meta-characters.
8309 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
8310 * configure.ac: Pass "." to git-version-gen.
8312 Avoid spurious test failures due to version skew.
8313 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
8315 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8317 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
8318 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
8319 Remove conftest.dSYM directory.
8320 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
8321 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
8322 Remove `conftest.*' recursively.
8323 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
8324 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8326 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
8328 Report and analysis by Jeff Squyres and Peter O'Gorman.
8330 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
8332 Fix typos in variable names.
8333 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
8335 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
8337 Document that $((expression)) is not portable.
8338 * doc/autoconf.texi (Shell Substitutions): Here.
8340 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8342 Ignore configure --help* errors due to LINENO-impaired shells.
8343 * tests/torture.at (Configuring subdirectories, Deep Package):
8344 In the --help* tests in read-only trees, make `.' temporarily
8345 writable again for the `stderr' file, and ignore errors due to
8346 the attempt to write configure.lineno.
8347 Report by Patrick Welche.
8349 2007-11-10 Jim Meyering <meyering@redhat.com>
8351 Generate package.m4 in build-dir, not srcdir.
8352 * tests/Makefile.am (package.m4): Adjust target.
8353 Don't redirect directly to $@.
8354 (CLEANFILES): Add package.m4.
8355 ($(TESTSUITE)): Depend on just-built package.m4, not the one
8357 When running $(AUTOTEST), search "." before searching $(srcdir).
8359 Avoid a race condition that would make parallel "distclean" fail.
8360 * tests/Makefile.am (distclean-generic): Replace the default,
8361 automake-provided rule with an identical one, but with an additional
8362 dependency on distclean-local. Simply adding the dependency would
8363 cause automake not to emit the rule at all.
8364 * BUGS: Building with -jN works, now.
8366 Distribute git-version-gen.
8367 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
8368 since GNUmakefile is distributed, and requires it for dist* rules.
8370 Remove two more generated files from version control.
8371 * INSTALL: Remove generated file.
8372 * lib/autoscan/autoscan.list: Remove generated file.
8374 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
8376 * GNUmakefile (PATH): Remove stray apostrophes; they become
8377 part of PATH, which isn't wanted here.
8379 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8381 New config files output variable `top_build_prefix'.
8382 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
8384 * doc/autoconf.texi (Preset Output Variables): Document it.
8386 Report by Bob Friesenhahn.
8388 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
8389 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
8390 function, to parametrize arithmetic with expr vs. the shell.
8391 Use it where possible.
8392 Suggestion by Benoit Sigoure.
8394 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
8396 Adjust the documentation of autotest WRT atlocal.
8397 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
8398 when using Automake, to write a rule to produce atlocal, since it's
8399 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
8400 distributed, not atconfig.in.
8402 2007-11-04 Eric Blake <ebb9@byu.net>
8404 Update list information.
8405 * README: Mention new autoconf-commit list.
8406 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
8408 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8410 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
8412 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
8414 * build-aux/.gitignore: Ignore mkinstalldirs.
8416 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
8418 2007-11-03 Jim Meyering <meyering@redhat.com>
8420 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
8421 * build-aux/git-version-gen: This syncs from coreutils.
8423 Adjust the build procedure so "make check" works reliably.
8424 * README-hacking: Include an extra step between "make" and
8425 "make check" to ensure that the latter passes.
8427 Use just-built tools, when possible.
8428 * GNUmakefile (PATH): Set and export here, ...
8429 (dummy): ... rather than here.
8431 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8432 and Andreas Schwab <schwab@suse.de>

8437 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8439 * configure.ac (AC_PREREQ): Require version 2.60, for
8440 AC_PROG_SED, AC_PROG_GREP.
8442 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>

8501 Make inter-release --version output more useful.
8503 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
8504 which indicates that it is built using the 19th change set
8505 (in _some_ repository) following the "v2.61a" tag, and that 58dd
8506 is a prefix of the commit SHA1.
8507 * build-aux/git-version-gen: New file.
8508 * configure.ac: Run it to set the version.
8509 (AM_INIT_AUTOMAKE): Don't check NEWS here.

8514 not configure.ac, now that the version number changes automatically.
8516 Ensure that $(VERSION) is up to date for dist-related targets.
8517 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
8518 git-version-gen doesn't match $(VERSION), but only for dist targets.

8591 Fix config header generation with AIX awk.
8592 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk

9924 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
9925 status of rm so we know when it failed.
9926 If cleaning of test dir failed before running the test, warn.
9927 Output the line separator in verbose mode before the warning
9928 to make clear the warning belongs to the following test.
9930 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
9932 * doc/autoconf.texi (Parentheses): Mention problem with (( in
9935 2007-02-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9936 and Paul Eggert <eggert@cs.ucla.edu>
9938 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix quoting
9939 errors introduced in last change.
9941 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
9943 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
9944 an actual carriage return. Use "ac_cr" to contain the actual
9946 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
9947 with traditional Awk and begin.
9948 * tests/torture.at (Limitations of Builtins): Document the problem
9949 with Bash 2.03 printf.
9950 (Substitute and define special characters):
9951 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
9953 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
9955 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
9956 input from /dev/null in awk test, so even Solaris /usr/bin/awk
9957 will not wait for input with a script containing only a BEGIN
9960 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
9962 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
9966 2007-02-02 Eric Blake <ebb9@byu.net>
9968 * NEWS: Update copyright.
9970 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
9972 * configure.ac: Update error message.
9973 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

9987 Add a new section for problems with @{#var} etc. Problem noted
9988 by Ralf Wildenhues. See:

9991 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9993 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
9994 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
9995 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
9996 substitution will still be done by the special code.
9997 Report by Jim Meyering.
9999 * doc/autoconf.texi (File System Conventions): Mention that
10000 $PATH_SEPARATOR is for the build system only.
10001 Report by Keith Marshall.
10003 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

10016 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
10018 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10020 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
10021 early on the reader side, drop stderr of the input to avoid
10022 `broken pipe' error output; this may happen even with shell
10023 builtin `echo' of some bash versions. Reports by Ian Macdonald
10024 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
10026 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10028 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
10029 separate items of `ac_user_opts', to avoid long lines.
10030 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
10032 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10034 * doc/autoconf.texi: Fix some typos.
10036 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
10038 Fix some wording problems noted by Paolo Bonzini in:
10039 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
10040 * doc/autoconf.texi (Signed Overflow Examples): Give more
10041 discussion about the allow_superuser_privileges example,
10042 and change it a bit to make things clearer.
10043 (Optimization and Wraparound): Clarify whether the compiler
10044 will generate an infinite loop for the example derived from
10045 Autoconf's mktime test.
10046 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
10047 Also, clarify unsigned multiplication overflow.
10049 2007-01-04 Eric Blake <ebb9@byu.net>
10051 * bin/Makefile.am (RELEASE_YEAR): New macro.
10052 (edit): Use it to supply correct copyright year to scripts.
10053 * bin/autoconf.as (version): Use it.
10054 * bin/autoheader.in ($version): Likewise.
10055 * bin/autom4te.in ($version): Likewise.
10056 * bin/autoreconf.in ($version): Likewise.
10057 * bin/autoscan.in ($version): Likewise.
10058 * bin/autoupdate.in ($version): Likewise.
10059 * bin/ifnames.in ($version): Likewise.
10061 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
10063 * doc/autoconf.texi (Integer Overflow): Revised based on today's
10064 feedback. The most important changes document what happens when
10065 you convert an out-of-range value to a signed integer type, and
10066 say that (sum < a) != (b < 0) reliably detects overflow when sum =
10069 * doc/autoconf.texi (Integer Overflow): Greatly expand and
10070 rewrite, taking notions from the recent discussion on the gcc and
10071 autoconf mailing lists; please see
10072 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
10073 and follow the many links.
10074 (Integer Overflow Basics, Signed Overflow Examples):
10075 (Optimization and Wraparound, Signed Overflow Advice):
10076 (Signed Integer Division): New sections.
10078 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
10080 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
10081 preprocessor macro arguments in traced name.
10082 * doc/autoconf.texi (Defining symbols): Document longstanding
10083 support for AC_DEFINE-ing macros with arguments, and document
10084 behavior when the same variable has multiple AC_DEFINEs.
10085 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
10086 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
10087 macros directly, giving much shorter and simpler code.
10089 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
10091 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
10092 space before "$ac_configure_args" to prevent a 'config.status
10093 --recheck' failure if ac_configure_args doesn't contain a leading
10094 space. This works around a problem with the XEmacs configure.ac,
10095 which uses the (undocumented) ac_configure_args variable
10096 inconsistently with Autoconf.
10098 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
10100 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
10101 Include <limits.h>, and use its INT_MAX to rewrite the
10102 j loop so that it does not overflow 'int'. Problem reported by
10104 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
10105 Play it safe by shifting left by 1 rather than multiplying by 2,
10106 as GCC is less likely to optimize this away when the value
10107 is signed (when it assumes overflow leads to undefined behavior).
10108 Also, don't assume time_t uses two's complement.
10110 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10112 * tests/torture.at (Substitute a 2000-byte string): Avoid using
10113 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
10114 dumps core on it. Report by Tim Rice.
10116 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
10118 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
10119 --disable-option-checking to --help output even when
10120 AC_PRESERVE_HELP_ORDER is not used.
10121 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
10122 --with argument, rather than argument with [-.] replaced by
10124 * NEWS: Fix typo in previous change; the news was in the
10127 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
10129 * NEWS: Warnings are now generated by default for unknown
10130 --enable-* and --with-* options.
10131 * doc/autoconf.texi (Option Checking): Renamed from
10132 (Configure Option Checking). Tighten up the wording a bit.
10133 (External Software, Package Options): Cross-reference to Option
10134 Checking, and use this to shorten our section.
10135 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
10136 "$x" to test "x$foo" != x.
10137 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
10138 Don't warn if $enable_option_checking is "no".
10139 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
10140 ac_unrecognized_opts to the empty string.
10141 Don't echo the unrecognized opts, as this might mishandle
10142 backslashes or leading -.
10143 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
10144 usage next to the other --disable-FEATURE options in the
10147 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
10149 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
10150 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
10151 Print warning for unrecognized --with and --enable options
10152 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
10153 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
10154 Disable option checking when subdirs are configured.
10155 (AC_OUTPUT): If warnings are enabled, print warning about
10156 unrecognized --with and --enable options at the end of
10157 the configure output (as well as at the beginning).
10158 * doc/autoconf.texi (Option Checking): New node.
10159 Document new option warning functionality.
10161 2006-12-16 Eric Blake <ebb9@byu.net>
10163 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
10164 * NEWS: Start news for current version.
10166 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
10168 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10169 Define HAVE_GETMNTENT to 1, not to the empty string.
10170 Problem originally reported by Jochen Friedrich in
10171 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
10173 This change prompted by a problem report by Andrey Simonenko in
10174 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
10175 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
10176 object-like macros only, in the traditional portable character
10178 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
10179 Warn about attempts to define things that are not identifiers.
10180 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
10181 awful hack that AC_DEFINEd macro names containing parentheses.
10183 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
10185 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
10186 too drastic, even if Texinfo in theory requires it for info mode.
10188 (config.status Invocation): Renamed back from Recreating a
10190 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
10191 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
10193 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
10195 * NEWS: Version 2.61a.
10197 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
10198 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10200 * NEWS: Document changes with echo and printf, and the lack
10201 of limits on the total size of multi-line values of substituted
10202 variables, and the AC_FUNC_FSEEKO fix.
10204 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
10206 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
10207 Writing configure.ac.
10208 (Autoconf Input Layout): Renamed from configure.ac Layout.
10209 (Recreating a Configuration): Renamed from config.status Invocation.
10210 (Obsolete Recreation): Renamed from Obsolete config.status Use.
10211 (acconfig Header): Renamed from acconfig.h.
10212 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
10213 (Writing Testsuites): Renamed from Writing testsuite.at.
10214 (Autom4te Cache): Renamed from autom4te.cache.
10216 * BUGS: Remove mention of VPATH problem, since it's now documented
10217 not to be a bug in the Autoconf build procedure itself, but rather
10218 a problem with the proprietary `make' programs.
10220 * doc/autoconf.texi (Build Directories): Add a cross reference
10223 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
10224 * doc/standards.texi: Sync from gnulib.
10226 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
10227 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
10228 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
10229 generated automatically.
10231 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
10233 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
10234 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
10235 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
10237 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
10240 `CEOF$ac_eof' special marker, the awk script cannot contain a
10241 line matching `^CEOF', so this is not needed any more.
10242 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
10243 special marker in the test.
10245 2006-12-06 Stepan Kasal <kasal@ucw.cz>
10247 * tests/tools.at (autom4te preselections): Use `find -newer';
10248 remove one of the sleeps.
10250 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
10251 more readable, using ...
10252 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
10254 * doc/autoconf.texi (autoheader Invocation): Do not double-
10255 quote the parameter of `AH_BOTTOM' in the example.
10257 2006-12-05 Stepan Kasal <kasal@ucw.cz>
10259 * doc/autoconf.texi (Configuration Headers): Remove the
10260 example with multiple input files.
10261 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
10262 multiple input files.
10264 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10266 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
10267 creating the awk substitution script, handle one input line at a
10268 time, so that the maximum length of a substituted (multi-line)
10269 value is not limited by the size of the sed pattern space.
10270 The trade-off is a slightly repetitive sed script.
10271 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
10272 can only have up to 7 characters, due to Solaris 10 /bin/sed.
10273 * tests/torture.at (Substitute a 2000-byte string): Increase the
10274 test with several long lines, they should not be caught by sed
10277 * tests/tools.at (autom4te preselections): New test, to flag
10278 entries missing from autom4te.cfg.
10279 Report by David Byron <dbyron@hheld.com>.
10281 * tests/torture.at (Substitute a 2000-byte string): Actually use
10282 AC_PROG_AWK, so the last change works as intended.
10283 (Substitute and define special characters): Likewise.
10284 (Substitute a newline): Likewise.
10286 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
10287 instead of `awk' consistently.
10288 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
10289 * tests/torture.at (Torturing config.status): Test both the
10290 result of AC_PROG_AWK and plain awk.
10291 (Substitute a 2000-byte string): Likewise.
10292 (Substitute and define special characters): Likewise.
10293 (Substitute a newline): Likewise.
10295 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
10297 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
10298 can be assigned to a function pointer. Problem reported by
10299 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
10300 part of a patch by Ralf Wildenhues in that same bug report.
10302 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
10304 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
10305 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
10307 2006-12-01 Eric Blake <ebb9@byu.net>
10309 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
10310 cross-compiling from cygwin to mingw.
10311 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
10312 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
10313 to lib/autoconf/c.m4.
10315 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10317 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
10318 string for more reliable failure. Wrap the entire test that
10319 causes the broken Solaris printf to dump core, in a subshell,
10320 so the segmentation fault message is reliably suppressed.
10321 Fix shell expansion errors by using /usr/ucb/echo always;
10322 avoid an error on systems without it by another subshell.
10323 Avoid m4 expansion of `$1'. Set the zeroth argument of the
10324 subshell-$as_echo to `as_echo', for better error message.
10326 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10328 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
10329 `BASH_SOURCE' contain a newline, set them to empty, as they may
10332 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
10334 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
10335 years and is too hard to maintain now. The last straw was
10336 reported by Jerker Baeck in
10337 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
10338 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
10339 * doc/autoconf.texi (Particular Functions): Move
10340 AC_FUNC_SETVBUF_REVERSED from here...
10341 (Obsolete Macros): ... to here. Say that it does nothing now.
10342 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10343 Turn into (almost) a no-op.
10345 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
10347 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
10348 These macros are obsolescent and new applications shouldn't need them.
10349 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):

10353 (AC_FUNC_VPRINTF): Likewise.
10354 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
10355 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
10356 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
10358 * doc/autoconf.texi (Setting Output Variables): Mention that
10359 @VAR1@VAR2 has unspecified behavior. Problem reported by
10361 * NEWS: Mention this.
10363 * Makefile.am: Put only a single '#' into the copyright notice,
10364 so that it's also present in the output file. Standardize wording
10365 in makefile copyright notices to match GNU coding standards.
10366 * bin/Makefile.am: Likewise.

10381 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
10382 in the sed script that mangles the awk script: delete up to the
10383 first exclamation mark only.
10384 * tests/torture.at (Substitute and define special characters):
10387 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10389 Rewrite config files generation: avoid quadratic growth in
10390 the number of substituted variables by using awk instead of sed
10391 for the bulk of the substitutions.
10392 * NEWS: Mention this.
10393 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
10394 forbidden in the output (and thus input) file.
10395 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
10396 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
10397 generate just one large awk script for substitutions,
10398 eliminating much of the earlier complexity, while adding some
10399 new complexity. Only expand the substitution templates at
10400 configure time, for smaller configure script size. If
10401 _AC_SUBST_FILES are used, test 'awk' for working getline support
10402 at config.status time. If absent, interpolate through the
10403 shell. The awk script was written with much help
10404 from Paolo Bonzini and Paul Eggert.
10405 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.

10409 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
10410 * tests/torture.at (Substitute a 2000-byte string): Also
10411 substitute a line with 1000 words, and a variable with several
10413 (Substitute and define special characters): Test awk special
10414 characters, and put substitution input strings `@foo@' in the
10415 output, to test that no recursion happens; test several other
10416 combinations from Paolo Bonzini.
10418 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
10420 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
10421 that replaced echo with AS_ECHO where this wasn't necessary.
10422 Problem reportd by Ralf Wildenhues.
10423 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
10424 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
10425 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
10427 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10429 * lib/freeze.mk (GREP): Removed, no need to initialize this.
10431 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
10433 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
10434 that traditional Awk lacks 3-arg "split". It has it.
10435 Mention that FS must be a single character, and a few other
10436 99-byte limits of traditional Awk.
10437 Mention that if (i in a) doesn't work with traditional Awk.

10445 (Single-quote-newline-BS-newline in command):
10446 Use printf '%s\n' instead of echo, for portability to hosts
10447 where echo interprets backslashes. This will break on hosts
10448 that lack printf, but for now let's assume all such hosts
10449 are dead (if not, we should get reports of test failures).
10451 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
10453 'echo' has some portability problems, when given a first argument
10454 with a leading '-', or when given any argument containing '\'.
10455 Avoid using 'echo' in these cases.

10481 * bin/autoconf.as: Redo verbose flag implementation, as the old
10482 scheme wouldn't work with AS_ECHO.

10484 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

10486 * lib/autotest/general.m4 (AT_INIT): Likewise.
10487 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
10488 rather than using a here-document to put the script into a file.

10491 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
10492 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
10493 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

10500 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
10501 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
10502 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
10503 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
10504 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
10505 Double-quote strings that would otherwise contain M4 comments.
10506 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
10508 * configure.ac (AC_INIT): Bump to 2.61a.
10511 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
10515 * configure.ac (AC_INIT): Bump to 2.61.

10519 Comment out for now, as this tests neither fails nor passes
10520 reliably. Problem reported by Ralf Wildenhues.
10522 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
10524 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
10525 in previous change, which caused test failures.

10529 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
10530 code for --enable, --disable, --with, and --without to...

10537 Import these changes from config via gnulib:
10539 2006-11-15 Ben Elliston <bje@gnu.org>

10599 benefit of platforms like Solaris+GCC where it is common to have a
10600 non-working g++ installation.

10613 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
10614 Imported from a similar patch to gnulib by Bruno Haible.
10616 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

10632 Automake 1.10 nor future Automake 11.1 (sic).
10634 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
10635 and Stepan Kasal <kasal@ucw.cz>
10637 Handle special characters in test case titles correctly.
10638 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
10640 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
10641 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
10642 argument. Extend to check titles printed by ./micro-suite and
10643 ./micro-suite -l and the title in micro-suite.log.
10644 (Backquote in a test title,
10645 Single-quote in a test title,
10646 Double-quote in a test title): Don't expect failure anymore.
10647 (Backslash in a test title): Put a non-whitespace character after the
10648 backslash so that Bourne shells might actually see it as an escape
10650 (Brackets in a test title,
10651 Pound in a test title,
10652 Comma in a test title,

10660 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
10661 The visible effect was a stray [] in the testsuite output.
10663 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10665 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

10668 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
10670 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
10671 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
10672 5363) simply issues a warning when dividing by zero at compile
10673 time. Problem reported by Elias Pipping.
10675 2006-10-26 Eric Blake <ebb9@byu.net>
10678 * doc/autoconf.texi (Evaluation Macros): Improve the example to
10679 show effect on macros that expand with commas.
10680 Reported by Joel E. Denny.
10682 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

10707 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
10708 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
10709 reported by Nelson H. F. Beebe for Coreutils 6.4.
10711 * tests/tools.at (autoconf --trace: user macros): Remove test
10712 for tracing multiline macros, since m4 1.4.7a uses a different
10713 way to number lines. Problem reported by Ralf Wildenhues.
10715 2006-10-24 Stepan Kasal <kasal@ucw.cz>
10717 * bin/autom4te.in (handle_m4): Do not redirect stdin to
10718 /dev/null since the heuristics for interactive behaviour was
10721 * bin/autom4te.in: With --force, always refresh the output
10722 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
10724 * bin/autoconf.as: Fix the verbose message at the end.
10726 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>
10728 * configure.ac (AC_INIT): Bump to 2.60c.

10743 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
10744 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
10746 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10748 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.

10791 (Imported from Automake.)
10792 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
10793 which incorrectly sets the mode of an existing destination
10794 directory. In some cases the unpatched install-sh could do the
10795 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
10796 system. We hope this is rare in practice, but it's clearly worth
10797 fixing. Problem reported by Alex Unleashed in
10798 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
10799 Also, don't bother to check for -m bugs unless we're using -m;
10800 suggested by Stepan Kasal.

10876 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
10877 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
10878 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
10879 Use a better substitute, by inspecting the output of "ls"
10880 rather than just using ":".
10881 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
10882 rather than AS_EXECUTABLE_P, since we needn't worry about
10883 non-regular files here.
10885 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
10886 due to configuration hassles with this. See Tonya Underwood's report
10887 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

10910 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
10911 comment about ac_cpp_err; it was incorrect, and anyway

10913 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
10914 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
10915 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
10917 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
10918 with werror_flag and conftest.err and so forth. This is more
10919 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
10920 and anyway the user shouldn't normally want to see this gorp logged.
10921 Problem reported by Ralf Wildenhues.
10922 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
10923 empty, not 'no', since the rest of the code uses 'test -z'.
10925 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
10927 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10928 Use a single call to AC_DO_TOKENS rather than multiple, for
10930 (_AC_LINK_IFELSE): Test that resulting file is executable.
10931 Problem reported by mwoehlke in
10932 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
10934 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
10935 than creating a file to use with test -x; this is much faster.
10937 2006-10-02 Bruno Haible <bruno@clisp.org>
10939 * lib/autom4te.in (Automake-preselections): Add
10940 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
10942 2006-09-27 Stepan Kasal <kasal@ucw.cz>
10944 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

10949 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

10957 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
10958 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
10959 include it, without including anything else.
10960 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
10962 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

10976 can apply to constants too, and that it checks for macro defns.
10977 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
10978 and simply cast the identifier to void. This handles structure
10979 values. Problem reported by Ralf Wildenhues.

11069 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
11070 for the existence of the directory at configure-time. That's
11071 too late, anyway. Problem reported by Stefan Seefeld.

11074 7.1.4 /usr/bin/posix/sh described by Tim Rice in

11087 to catch glibc bug 2821
11088 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.

11195 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

11302 * doc/autoconf.texi (Particular Programs): Mention that
11303 @INSTALL@ and @MKDIR_P@ may vary for different output files.
11304 Reported by Alexandre Duret-Lutz.
11306 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
11308 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
11309 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by

11319 longer supported by Sun.
11321 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
11323 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
11324 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
11325 -Wundef -Werror". Problem reported by David Fang in

11346 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
11348 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
11349 problems with arg script text that doesn't end in newline, and
11350 with '-e a...'. Problems reported by Ralf Wildenhues.
11352 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
11354 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
11355 check for libXt by a check for libX11.
11357 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11359 * doc/autoconf.texi (config.status Invocation): Adjust according
11362 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11364 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
11365 --help' should mention that `--version' outputs configuration
11366 settings. Report by Bruno Haible.
11368 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
11370 Fix test suite failures reported by Pierre in

11386 less skeptical about "volatile", after discussion with
11387 Bruno Haible on bug-gnulib.
11388 (Limitations of Usual Tools): Warn about sed stripping
11389 leading white space from text. From Bruno Haible.
11391 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
11393 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
11394 compiler complains about it, even if things works after the
11395 complaint. Problem reported by Peter O'Gorman.
11397 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
11398 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
11399 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
11401 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
11403 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
11404 after -R regardless of host. Patrick Welche reports that this

11415 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
11416 under AC_C_VOLATILE.
11417 (Volatile Objects): Be a little less skeptical about what
11418 "volatile" means. Derived from thoughts by Ben Pfaff in
11419 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
11421 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11423 * doc/autoconf.texi: Fix some typos.
11425 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
11427 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
11428 more globally, since the 2006-06-30 patch didn't suffice. Problem
11429 reported by Keith Marshall. Also, don't bother with builddir2,
11430 since it shouldn't be needed any more.
11432 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
11434 * doc/autoconf.texi (Generic compiler characteristics):
11435 Document AC_COMPUTE_INT. Fix wrong statements on Default

11443 * NEWS: Document change.
11445 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
11447 * doc/autoconf.texi (Volatile Objects): New section.
11449 * NEWS: Document previous change.
11451 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
11453 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
11454 Require that long long int be at least 64 bits wide. C99 requires
11455 this and enough programs depend on it so we should check for it.
11456 Bruno Haible reports in
11457 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
11458 that long long int is 32 bits wide with some nonstandard compilers.
11459 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
11461 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
11463 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
11464 to a nonexistent file, so that we don't have to worry about
11465 a local site configuration that doesn't use /usr/local.
11466 Problem reported by Keith Marshall in
11467 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
11469 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
11471 * doc/autoconf.texi: Be more consistent about using @acronym with
11472 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
11473 quite right (it talked about "OSF/Tru64", even though the
11474 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
11475 and it even mentioned "OSF 4"!) and at this point there's little
11476 reason to talk about OSF any more, since it died in 1994.
11477 (Specific Compiler Characteristics): Simplify example of
11478 negative-size array.
11479 (File Descriptors): Reorder to make the text flow better.
11480 Remove joke about "appreciate the various levels"; I didn't get it.
11481 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
11482 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
11483 (File Descriptors, Limitations of Usual Tools):
11484 Tone down the advice against renaming or removing open files.
11485 (Limitations of Usual Tools): Add a new section, on 'rm'.
11487 2006-06-26 Stepan Kasal <kasal@ucw.cz>
11489 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
11490 -lXt in LIBS, idea from Karsten Hopp; this was due since
11493 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
11494 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
11495 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
11496 (which belong to Xt, not X itself). See Debian bug 327655.
11498 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11500 * configure.ac (AC_INIT): Bump to 2.60a.
11503 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11507 * configure.ac, NEWS: Update.
11509 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11511 * config/texinfo.tex: Sync from upstream.
11513 * bin/autom4te.in (handle_traces): Transform the `@S|@'
11514 quadrigraph correctly in traces.
11516 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
11519 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
11520 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
11522 * doc/autoconf.texi (Changed Directory Variables): New node,
11523 to document the whole `datarootdir' business a bit better.
11525 * tests/torture.at (datarootdir workaround): Extend test.
11526 Prompted by report by Alexandre Julliard.
11528 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
11530 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
11531 when using default mode of IBM C 6 for AIX. Problem and two-line
11532 fix reported by Larry Jones.
11534 2006-06-22 Alexandre Julliard <julliard@winehq.org>
11536 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
11537 about literal '${datarootdir}' if a definition is found in the
11540 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
11542 * NEWS: Use "M4" rather than "m4" when appropriate.
11543 Problem reported by Eric Blake.
11544 * doc/autoconf.texi: Likewise.
11545 Use @acronym around BSD, GCC, and GNU when appropriate.
11546 (Why GNU M4): Renamed from "Why GNU m4".
11547 (Redefined M4 Macros): Mention that Posix
11548 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
11549 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
11552 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11554 * bin/autom4te.in (handle_output): Do not forbid the empty
11556 * tests/tools.at (autoconf: the empty token): New test.
11558 2006-06-20 Stepan Kasal <kasal@ucw.cz>
11560 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
11561 calls, so that we do not care whether they are LIFO or FIFO;
11562 in the m4_wrap, do not check which diversion is the topmost
11563 one, just check that the stack is balanced at the end.
11564 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
11565 base diversion forever--pop the previous diversion before
11566 opening the new one; consequently, remove the m4_wrap call.
11567 * lib/autotest/general.m4 (AT_INIT): Likewise.
11568 * tests/m4sugar.at: Do not use
11569 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
11571 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
11572 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11574 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
11575 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
11576 Rework example of m4wrap token-pasting trouble so that it doesn't
11577 care whether it's LIFO or FIFO.
11578 Fix some "contrary to"s that are awkward in English.
11580 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11582 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
11583 to `yes' instead of `int$1_t' if the type is found, for more
11584 consistent configure output (where $1 is the number of bits).
11585 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
11586 Suggested by Bruno Haible.
11588 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
11589 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
11590 with system headers. Report by Bruno Haible.
11592 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11594 * config/config.guess, config/config.sub: Sync from upstream.
11596 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
11597 in order to avoid picking up an older installed frozen m4sh.m4f.
11598 Besides an outdated shell startup, this could have been created
11599 by an earlier M4 version with incompatible frozen file format.
11601 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
11603 * README: Recommend m4 1.4.4 instead of 1.4.3..
11604 * doc/autoconf.texi: Likewise.
11605 (Special Chars in Names): Say that $(.FOO) is portable, as
11606 suggested by Stepan Kasal.
11607 (Installation Directory Variables, Build Directories):
11608 (Automatic Remaking, Subdirectories, Fortran Compiler):
11609 (Making testsuite Scripts, Defining Directories):
11610 Quote variable usages better.
11611 (Making testsuite Scripts): Add clean-local rule to makefile
11612 snippet, by Eric Blake.
11613 (Installation Directory Variables): Fix table item font.
11614 Reword slightly to clarify. Generalize advice about
11615 not using special characters to include all file-related
11616 vars, not just VPATH.
11617 (Special Chars in Variables): Warn about special characters in
11619 (Assignments): Clarify default-value example as suggested by
11621 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
11622 (Special Shell Variables): Note leading ./ or ../, as suggested
11624 (Limitations of Builtins): Under cd, warn about CDPATH.
11625 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
11628 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11630 * doc/autoconf.texi (Configuration Actions): Remove duplicate
11631 `@var', for texi2html.
11632 (Systemology): Some more word wrapping, for DVI output.
11633 (autom4te Invocation): The short option for `--melt' is `-M',
11636 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
11638 * doc/autoconf.texi: More formatting and English tweaks,
11639 many suggested by Ralf Wildenhues.
11640 Reword to avoid "@code{...}'s" and the like, since it's ugly
11641 with Emacs info mode. discontents -> woes.
11642 Put a few "will"s back. time stamp -> timestamp.
11643 side-effect -> side effect.
11645 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
11647 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
11648 Warn about $@ not persisting. Problem reported by Julien Danjou in
11649 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
11650 (Special Chars in Names): Renamed from Leading _ in Macro Names.
11651 Mention other special chars, too.
11653 2006-06-14 Eric Blake <ebb9@byu.net>
11655 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
11657 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
11659 * doc/autoconf.texi: Some systematic minor improvements, as
11660 follows. Use "makefile" when talking about makefiles
11661 generally (which might be named "makefile" or "Makefile" or even
11662 "foo.mk"), "Makefile" when talking about a specific makefile
11663 called "Makefile". This unclutters the text from weird quotes
11664 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
11665 values" rather than "@var{foo}s" and similar constructs containing
11666 "}s". Use "Make rules" rather than "Makefile rules". Minor
11667 English-language improvements. Change the prefix "sub-" to "sub"
11669 Put blank lines around examples more consistently.
11670 Avoid "rather" and "very" as intensifiers.
11671 Avoid "will" as an auxiliary.
11672 (Limitations of Make): Split this node into....
11673 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
11674 (Leading _ in Macro Names, Backslash-Newline-Newline):
11675 (Backslash-Newline Comments, Long Lines in Makefiles):
11676 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
11677 (obj/ and Make, make -k Status, VPATH and Make):
11678 (VPATH and Double-colon, $< in Explicit Rules):
11679 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
11680 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
11681 New nodes, resulting from splitup of Limitations of Make.
11682 All cross-references changed. Raise the top node from
11683 a section to a chapter, and all subnodes accordingly.
11684 Redo the introductory wording to match the new organization.
11685 (Installation Directory Variables): Use an example that is
11686 closer to what Autoconf actually does. Mention that VPATH's
11687 value should not contain metacharacters or white space.
11688 (Fortran Compiler): Fix a VPATH bug in an example.
11689 (Leading _ in Macro Names): Mention that this problem is no longer
11690 of practical concern.
11691 (VPATH and Make): Reword the advice to make it clearer
11692 that Autoconf and Automake support VPATH in non-GNU make, but
11693 many packages have bugs in this area.
11694 ($< in Explicit Rules): Refer to Build Directories rather
11695 than using a (non-VPATH-safe) example.
11696 (Automatic Rule Rewriting): Mention the sort of disaster that
11697 can ensue with Solaris-style rule rewriting with VPATH.
11699 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11701 * doc/install.texi (Compilers and Options): Weaken the
11702 suggestion to use GNU make for VPATH builds.
11704 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
11705 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
11707 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
11708 in regular expression.
11710 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11712 * doc/autoconf.texi (Installation Directory Variables):
11713 Drop extra @samp from `@table @samp' item.
11714 (Limitations of Usual Tools): Comment fix.
11715 Do not nest @samp just to point to other table items.
11716 (Writing testsuite.at) <AT_CHECK>: The second argument to
11717 `@dvar' is already @samp'ed.
11718 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
11719 do not use @var in the second argument.
11721 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
11723 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
11724 $as_shell.exe too. Problem reported by Andreas Buening in
11725 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
11727 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11729 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
11730 `unused variable' compiler warning, for `-Wall -Werror'.
11731 Reported by Jaap Haitsma in
11732 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
11734 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
11736 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
11737 case the compiler dumps core. Problem reported for
11738 OpenServer 5.0.7 by Tim Rice in
11739 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
11740 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
11743 2006-06-06 Tim Rice <tim@multitalents.net>.
11745 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
11746 "ERROR" only shows up in "make check" output if there is an
11749 2006-06-06 Eric Blake <ebb9@byu.net>
11751 * tests/tools.at (automatically allowed tokens): Fix typo.
11753 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
11755 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
11757 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
11758 typically overflows on x86 CPUs, even though the C standard
11759 requires otherwise.
11761 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11763 * configure.ac (AC_INIT): Bump to 2.59e.
11766 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11770 * config/texinfo.tex: Sync from upstream.
11772 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
11773 seen, invoke libtoolize with `--ltdl' argument.
11774 * lib/autom4te.in (Autoreconf-preselections): Adjust.
11776 Suggested by Eric Blake.
11778 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
11780 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
11781 reported by Ralf Wildenhues.

11790 * doc/autoconf.texi: Modernize some of the references to Solaris.
11792 2006-06-05 Stepan Kasal <kasal@ucw.cz>
11794 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
11795 message issued by AC_REQUIRE.
11796 * tests/m4sugar.at: Check m4_require's error message.
11797 * tests/base.at: Check AC_REQUIRE's error message.
11798 * tests/local.at (AT_CHECK_M4): New macro, almost identical
11800 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
11802 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
11803 `expout' as the last parameter.
11804 * tests/tools.at: Adapt to the above change.
11806 2006-06-04 Stepan Kasal <kasal@ucw.cz>
11808 * doc/autoconf.texi (Limitations of Usual Tools): Correct
11809 information about race-free implementations of mkdir.
11811 2006-06-04 Eric Blake <ebb9@byu.net>
11813 * bin/autoreconf.in (help): Document M4 environment variable.
11814 * bin/autoconf.as (Usage): Likewise.
11815 * bin/autom4te.in (help): Likewise.

11818 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
11820 * NEWS: GNU make now recommended for VPATH builds.
11821 Mention that some macros are now documented to be obsolescent.
11822 * doc/autoconf.texi:
11823 Prefer "current" to "modern" to describe
11824 currently-used (albeit perhaps old-fashioned) hosts.
11825 Mention which ancient features no longer need to be worried about.
11826 setgid -> set-group-ID
11827 setuid -> set-user-ID (these are the Posix terms)
11828 Fix some misuses of "only".
11829 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
11830 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
11831 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
11832 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
11833 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

11836 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
11837 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
11838 Mention that these macros are obsolescent.
11839 (Installation Directory Variables): shall -> should
11840 (File Descriptors): Mention that 0, 1, 2 might get reopened.
11841 Mention that it's now safe to use 3 and 4.
11842 (Limitations of Usual Tools): cp -r is now specified by Posix.
11843 Omit longwinded and obsolescent discussion of cp -f.
11844 Modernize discussion of expr, ls.
11845 (Limitations of Make): Modernize discussion of VPATH builds.
11846 Mention $? as a workaround in some cases.
11847 * doc/install.texi (Basic Installation):
11848 Mention "./configure; make; make install" first. Be more
11849 specific about why this file is generic. Remove unnecessary
11850 parens. Remove misleading "only". Remove obsolete advice
11851 about csh. Don't say "configure" takes awhile; say it
11852 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
11853 and CC=c99 rather than CC=c89, as these are blessed by current
11854 Posix. Recommend GNU make if doing a VPATH build.
11856 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
11858 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
11859 examples involving shell prompts.
11861 2006-06-02 Stepan Kasal <kasal@ucw.cz>
11862 and Paul Eggert <eggert@cs.ucla.edu>
11864 * doc/autoconf.texi (Here-Documents): Add details about the
11865 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
11866 use "here-documents" instead of "here documents".
11868 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11870 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

11875 anywhere in directory names.
11877 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
11879 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
11880 about quoting the case statement, just in case.
11881 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
11882 was fixed in ksh93g; reported by Ralf Wildenhues.
11884 2006-05-31 Stepan Kasal <kasal@ucw.cz>
11886 * doc/autoconf.texi (System Services): Do not document
11887 overriding EXEEXT via ac_cv_exeext=ext.
11888 (Particular Programs) <AC_PROG_MKDIR_P>:
11889 Document that ${MKDIR_P} understands --.

11893 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11895 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
11896 argument with leading hyphen. Problem reported by Paul Eggert.
11898 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11900 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
11901 about quoting ac_try: quote all of it, if any of it seems suspicious.
11902 This means we don't have to worry about ${ or sed any more.
11903 Also, double-quote the case statement, to work around misuses via
11904 underquoting as reported by Ralf Wildenhues in
11905 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
11906 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
11907 undocumented and dangerous macro.
11908 Problem reported by Ralf Wildenhues in
11909 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

11917 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11919 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
11920 since evidently some packages rely on the old, broken behavior.
11921 Problem reported by Ralf Wildenhues in
11922 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
11923 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
11924 pre-2006-05-26 definitions, but leave in the comments that
11925 these macros are dangerous and should not be used.
11926 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
11927 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
11928 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
11929 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
11930 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
11932 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
11934 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
11935 the use of 'tr', since this is our only use of 'tr'.

11938 and Paul Eggert <eggert@cs.ucla.edu>
11940 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
11941 Don't assume 'grep' works on long lines, since AIX grep doesn't.
11943 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11945 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
11946 the output file in the `${datarootdir}' test.
11948 2005-05-28 Stepan Kasal <kasal@ucw.cz>
11949 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11951 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
11952 mention of `datarootdir' in the input file(s), but literal
11953 `${datarootdir}' in the output file, and we haven't warned yet,
11954 then warn as well: the user may have (erroneously) used
11955 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
11956 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
11957 * tests/torture.at (datarootdir workaround): Extend this test.
11960 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11961 and Paul Eggert <eggert@cs.ucla.edu>
11963 * doc/autoconf.texi (autoheader Invocation): The first argument to
11964 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
11965 alternatives and clear up the language a bit.
11967 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
11969 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
11970 ac_config_guess, ac_config_sub, ac_configure.
11971 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11972 Fix typo that prevented an unnecessary space from being removed.
11973 Problems reported by Ralf Wildenhues in:
11974 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
11976 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
11978 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
11979 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
11980 Don't use the term "thread-safe" to talk about mkdir race
11981 conditions, since the problem is more a process than a thread
11982 issue. Problem reported by Stepan Kasal in:
11983 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
11984 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
11985 the test for 'install' more closely. Look at MKDIR_P first.
11986 Look in the PATH, and at /opt/sfw/bin.
11987 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
11988 Don't bother to try mkdir -p, since we already check mkdir --version;
11989 just look at the version number. (There's no easy way to check
11990 for race-free implementations.)
11991 * tests/tools.at (autoconf: subdirectories): Adjust to above
11992 changes, since MKDIR_P now might end in "/mkdir -p".
11994 * doc/autoconf.texi (autoheader Invocation): Mention that the
11995 first arg of AC_DEFINE_UNQUOTED must be a literal.
11996 Problem reported by Ben Pfaff in
11997 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
11999 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
12000 * doc/autoconf.texi (Special Chars in Variables): New section.
12001 (Preset Output Variables): Warn about special chars in CPPFLAGS.
12002 (Installation Directory Variables): Quote $(datadir) better.
12003 (Limitations of Builtins): Describe some of eval's trickiness.
12005 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
12006 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
12007 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
12008 in front of every arg, not just trailing args. Quote apostrophes.
12009 (_AC_EVAL_ECHO): New macro.
12010 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
12011 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
12013 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
12014 exposed by quoting of eval argument. Put the command on line line
12016 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
12017 (_AC_PATH_X, AC_PATH_X): Quote more safely.
12018 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
12019 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
12020 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
12021 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
12022 Use eval more safely.
12023 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
12024 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
12026 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
12027 lines, exposed by quoting of eval argument.
12029 2006-05-26 Stepan Kasal <kasal@ucw.cz>
12030 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12032 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
12033 initialization of `ac_cv_exeext', do not override it if it was
12034 already set, unless it was set to `no', for compatibility with
12035 Autoconf-2.13, and comment this.
12036 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
12037 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
12038 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
12039 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
12040 Document that this test may be overridden by setting
12043 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12045 Revert these two patches:
12047 2006-04-06 Eric Blake <ebb9@byu.net>
12048 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
12049 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
12052 2006-04-01 Stepan Kasal <kasal@ucw.cz>
12053 Clean up _AC_COMPILER_EXEEXT* macros.
12054 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
12055 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
12056 ac_file to the name of the default output file and call
12057 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
12058 initial `rm' of the candidate files...
12059 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
12060 the same list in subsequent `rm' calls, and for the temporary
12061 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
12062 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
12063 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
12064 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
12065 no longer needed) by libtool. Make it a cache check.
12066 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
12067 copied here by mistake.
12068 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
12069 _AC_COMPILER_EXEEXT.
12070 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
12071 _AC_COMPILER_OBJEXT directly.
12072 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12074 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12076 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
12077 Fix description of how the buggy `sed' works.
12079 2006-05-25 Noah Misch <noah@cs.caltech.edu>
12081 Sync from Automake:
12083 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
12084 ENOLCK. Only mention `make -j' when applicable. Only raise
12085 fatal errors when `make -j' is involved. Improve error message.
12087 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12089 * doc/autoconf.texi (Here-Documents): We now know more about
12090 the variable expansion in here documents bug.
12091 Thanks to Tim Rice and Stepan Kasal.
12093 * doc/autoconf.texi (Making testsuite Scripts): Add an example
12094 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
12096 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12098 * tests/autotest.at (Multiline command from M4 expansion):
12099 No failure to be expected if the shell quotes newlines in
12100 commands in the `set -x' output. Report by Tim Rice.
12103 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
12105 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
12106 expansion in the here-documents used by config.status, as that
12107 runs afoul of the Korn shell version M-12/28/93d bug described in
12108 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
12109 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
12110 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
12112 2006-05-23 Jim Meyering <jim@meyering.net>
12114 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
12115 Fix typo introduced with 2006-04-02 change. It reversed the sense
12118 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
12120 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
12121 ac_dB slightly, to save bytes in the script.
12122 Max out at 50 lines, rather than 96; this is more likely
12123 (though not guaranteed) to avoid obscure 'sed' failures.
12125 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12127 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
12128 `tr -d -' as bad option argument. Work around this by deleting
12129 an unrelated character.
12130 Report by Tim Rice <tim@multitalents.net>.
12132 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
12133 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12134 Stepan Kasal <kasal@ucw.cz>
12136 * doc/autoconf.texi (Particular Programs): Do not promise that
12137 we always prefer the GNU version of the program, and that we
12138 search according to PATH; both rules can have exceptions.
12139 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
12140 AC_PROG_SED. Move descriptions of limitations
12141 to the Limitations of Usual Tools section.
12142 (Limitations of Usual Tools) <sed>: Mention script length
12143 limitations with Solaris /usr/ucb/sed.
12144 <grep>: Fix wording for empty alternative. Mention that -c and
12145 -l should not be combined, and that -E and -F should not be
12148 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
12149 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12151 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
12152 limits in Solaris 8 /usr/ucb/sed by testing a long script.
12154 2006-05-22 Stepan Kasal <kasal@ucw.cz>
12156 * doc/autoconf.texi (Defining Symbols): Literal parameter of
12157 AC_DEFINE is now passed to m4_pattern_allow.
12158 * NEWS: Mention that; likewise for AC_SUBST.
12159 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
12160 the parameter to m4_pattern_allow.
12161 * tests/tools.at: Add a check for that.
12163 2006-05-22 Stepan Kasal <kasal@ucw.cz>
12165 * lib/autoconf/status.m4: Fix typos.
12167 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12169 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
12170 only the files that this macro generates.
12172 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
12174 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
12175 the HP-UX sed limitation of 99 commands, labels do not count.
12176 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
12178 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
12180 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
12182 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
12183 Import the following fix from coreutils:
12185 2006-01-13 Jim Meyering <jim@meyering.net>
12187 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
12188 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
12189 not double-quote uses of that variable, to accommodate the rare
12190 case in which getmntent is available in none of the libraries
12191 checked. This happens at least on FreeBSD 5.0.
12193 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
12195 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
12196 ac_config_guess, ac_config_sub, and ac_configure, since evidently
12197 some other programs unwisely rely on these undocumented vars.
12198 But put in warning comments about them.
12199 Problem reported by Ralf Wildenhues in
12200 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
12201 * NEWS: Document that these variables are intended to go away.
12203 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12205 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
12206 and set the language to C++ (analogous to the equivalent Fortran
12209 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
12210 * doc/autoconf.texi (C++ Compiler): Document it.
12211 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
12214 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
12216 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
12217 that caused config.status to generate 100-command sed scripts; the
12218 portable limit is 99.
12220 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12222 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
12223 variable `ac_d' instead of `d' to avoid infringing namespace.
12224 Report by Ralf Menzel.
12226 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
12228 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
12229 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
12230 * tests/tools.at (autoconf: subdirectories): New test, taken from
12231 the corresponding problem report by Ralf Wildenhues in:
12232 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
12234 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
12235 Quote some uses of shell variables if they might suffer unexpected
12236 globbing. This doesn't fix all instances of quoting problems that
12237 I found, just the easy ones that look safe.
12238 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
12239 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
12240 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
12241 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
12242 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

12249 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12251 * bin/autoreconf.in ($help): Reword according to the manual.
12252 Suggested by Olly Betts.
12254 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
12255 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12257 * bin/autoreconf.in: Pass the directory argument to
12258 `require_configure_ac'. Fix comment.
12259 * tests/torture.at (Configuring subdirectories): Expose this.
12260 Reported by Olly Betts.
12262 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12264 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
12265 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
12266 Automake as follows:
12268 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
12269 `$configure_in' instead of `configure.in', to preserve
12270 directory component.
12272 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12274 * config/config.guess, config/config.sub, config/texinfo.tex,
12275 doc/make-stds.texi, doc/standards.texi: Sync from upstream.

12279 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
12280 test for C99 conformance; (bool) 0.5 is an integer constant
12281 expression, but (bool) -0.5 is not. Problem reported by Fedor
12282 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
12284 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
12286 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
12287 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
12288 Warn about obsolete install-sh files. Remove stray sentence
12289 fragment and fix cross reference.
12290 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
12291 install -d; this undoes the 2006-05-10 change.
12292 (MKDIR_P): Mark with AN_MAKEVAR.
12293 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
12294 that we don't require $INSTALL to be thread-safe. Move comments
12295 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
12296 of AC_PROG_INSTALL. Output a message saying that we're checking
12297 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
12298 MKDIR_P instead of AC_SUBST.
12299 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
12300 Special magic for MKDIR_P, too.
12301 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
12303 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
12305 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
12307 Sync from Automake, as follows:
12309 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12310 * config/install-sh: Initialize IFS, so field splitting isn't
12312 * config/mkinstalldirs: Likewise.
12313 * config/missing: Remove superfluous quotes. Replace all uses of
12314 `[' by `test', for consistency, and for..
12315 * config/missing (sed_minuso, sed_output): New variables.
12316 (autom4te, help2man, makeinfo): Use them. Unifies detection of
12317 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
12318 Fixes `missing' to detect `--output' for help2man. Fixes
12319 PR automake/483. Report by Dennis J. Linse.
12320 (autom4te): Document in `missing --help'.
12322 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
12324 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
12325 * config/install-sh: Don't use 'path' to talk about file names,
12326 as per GNU coding standards. Close a race condition reported by Ralf
12327 Wildenhues and Stepan Kasal. There is still a race condition
12328 on hosts that predate Posix 1003.1-1992, but we can't help this.
12329 Don't mishandle weird characters like space on pre-Posix hosts.
12330 Invoke mkdir at most once per dir arg on pre-Posix hosts.
12331 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
12332 AC_PROG_MKDIR_P from AS_MKDIR_P.
12333 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
12334 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
12335 earlier editions are not (including Automake 1.8.3).
12336 Do not suggest mkinstalldirs for thread-safety.
12337 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
12338 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
12339 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
12340 presence of special characters and race conditions.
12341 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
12342 in Autoconf's name space.
12344 2006-05-10 Bruno Haible <bruno@clisp.org>
12345 and Paul Eggert <eggert@cs.ucla.edu>

12348 from Automake with minor changes.
12349 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
12351 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
12353 * config/install-sh: Update to Automake CVS version, as follows:
12354 2006-04-25 Stepan Kasal <kasal@ucw.cz>
12355 * lib/install-sh: Simplify the expr implementation of dirname.
12356 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
12357 * lib/install-sh: Handle --, and diagnose unknown options.
12359 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12361 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
12362 `./autom4te' to create `./testsuite', since the `all' target
12363 will ensure its presence, but `installcheck' should not create
12364 the uninstalled wrappers.
12366 * tests/torture.at (Unusual Automake input files): Skip if we
12367 detect automake < 1.8.
12369 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12371 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
12372 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
12373 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
12376 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12378 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
12379 munge (multiple) white space and other oddities.
12380 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
12381 single quotes in variable assignment.
12382 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
12383 and similar failures by adding multiple spaces, tabs, and other
12384 special characters.
12385 Report and different test suggested by Francesco Romani
12386 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
12388 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
12389 single quotes, we only need to search for single quotes; this
12390 both simplifies the search pattern, and makes us less
12391 susceptible to `echo' variations for arguments not containing
12393 (_AC_ARG_VAR_VALIDATE): Likewise.
12395 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12397 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
12398 `$*' and IFS concatenation issue with traditional shells and
12399 bash-2.04. Report by Seanster@Seanster.com.
12401 2006-05-03 Bruno Haible <bruno@clisp.org>
12403 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
12404 precisely which Mac OS X versions have the od problem.
12406 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
12408 * doc/autoconf.texi: Use @option systematically.
12410 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
12411 and Bruno Haible <bruno@clisp.org>
12413 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
12415 (Integer Overflow): Mention the special case of integer division
12418 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12420 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
12421 traditional shells like the Solaris one that do not use the
12422 first IFS character for assembling `$*'.
12423 Prompted by a related report from autoconf_bug@nro.ca.
12425 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
12426 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12428 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
12429 Mention more problems with the -e option.
12431 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12434 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
12436 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
12437 in URLs to improve DVI formatted output (requires texinfo 4.6).
12438 (System Services, Systemology, Shellology): Likewise.
12439 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
12442 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
12444 (Runtime): Fix macro argument names to match description:
12445 `action-if-found' -> `action-if-true' and similarly.
12446 (Obsolete Macros): Likewise.
12447 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
12448 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
12449 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
12451 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12453 * doc/autoconf.texi (Limitations of Make): Clean up markup.
12456 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

12468 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
12469 (Integer Overflow, Null Pointers, Buffer Overruns):
12470 (Floating Point Portability, Exiting Portably): New sections.
12471 (Writing Test Programs): Fix some langauge. Recommend exiting
12472 with status 1, not merely nonzero. Clarify exit declaration.

12477 2006-04-25 Stepan Kasal <kasal@ucw.cz>
12479 * bin/autoconf.as (me): Replace by as_me.
12481 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
12483 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
12484 since as_me isn't set yet.
12486 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
12488 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
12489 a few minor bugs in this area.
12491 * doc/autoconf.texi (Programming in M4sh): Comment out the
12492 documentation of AS_BASENAME, for now.
12493 (Shell Substitutions): Do not use AS_DIRNAME in an example.

12496 * bin/autoconf.as (me): Don't use AS_BASENAME.
12497 (dir): Remove the unused variable.
12498 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
12499 AS_DETECT_REQUIRED. All uses changed.
12500 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
12502 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

12512 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
12514 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
12515 of "run time" and "run-time" changed to "runtime", for consistency.

12524 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12526 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
12527 Archive is not officially `GNU' any more. Update URL.
12528 (Defining Directories): Likewise
12529 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
12531 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12533 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
12534 newline from the `trap' code to finish `config.log'; the NetBSD
12535 /bin/sh resets the exit status after an empty command, as
12536 documented in doc/autoconf.texi.
12537 Reported by Dalibor Topic <robilad@kaffe.org>.
12539 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
12541 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
12542 Suggested by Bruno Haible.
12544 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
12546 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
12547 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
12548 Instead, just list the shells that we know work.
12549 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
12550 changed. Be more cautious about the _cv_ variable.
12551 * tests/tools.at (Syntax of the shell scripts): Check the
12552 _cv_ variable once, at first, to avoid an internal autoconf error
12553 when sh -n does not work.
12555 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12557 * lib/Autom4te/FileUtils.pm: Sync from Automake.
12559 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
12561 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
12562 use ">&-" since we're only 99.999% sure that this is portable,
12563 and since the MinGW bug is fixed in a different way.
12564 * lib/autotest/general.m4 (AT_INIT): Likewise.
12566 2006-04-16 Stepan Kasal <kasal@ucw.cz>
12568 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
12569 before opening config.log, to avoid hitting a bug on MinGW.
12571 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
12573 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
12574 AS_MESSAGE_LOG_FD before reopening it onto the log file.
12575 This works around a MinGW bug reported by Eric Paire.
12576 Make sure that all writes to the log file append to it,
12577 rather than possibly losing data.
12578 * lib/autotest/general.m4 (AT_INIT): Likewise.
12580 2006-04-14 Stepan Kasal <kasal@ucw.cz>
12582 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
12585 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12589 * configure.ac (AC_INIT): Bump to 2.59d.
12591 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12595 * Makefile.maint (news-date-check): Do not require a leading `*'
12596 before the release date in NEWS.
12598 2006-04-12 Stepan Kasal <kasal@ucw.cz>
12599 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12601 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
12602 the instantiated file do not contain the string 'datarootdir'
12603 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
12604 @mandir@, replace the reference '${datarootdir}' by the value.
12605 * tests/torture.at (datarootdir workaround): New test.
12606 * NEWS: Advertise this temporary fixup.
12607 Based on a patch by Bruno Haible, reported and analyzed by
12608 Paul Eggert and Noah Misch.
12610 2006-04-12 Eric Blake <ebb9@byu.net>
12612 * tests/autotest.at (Debugging a failed test): Fix comment.
12614 2006-04-12 Stepan Kasal <kasal@ucw.cz>
12616 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
12617 all the changes since 2006-04-07.
12619 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12621 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
12622 succeeded, but `ln -s file dir' failed, take care to remove the
12623 leftover target before the next test, to prevent its spurious
12624 failure; also make sure `ln file dir' works before selecting it.
12625 Thanks to Keith Marshall for pointing this out.
12628 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
12629 assignments in `at_debug_args', so that we put them correctly
12630 in the `run' script.
12631 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
12632 Reported by Eric Blake.
12634 2006-04-11 Eric Blake <ebb9@byu.net>
12636 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
12637 top-level tests after micro-suite has been run. Used in...
12638 (Debugging a successful test, Debugging script and environment),
12639 (Debugging a failed test): ...these new tests. The first of these
12641 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
12642 macro, split out from...
12643 (AT_INIT): ...here, so that using -d also generates a run script.
12644 Document that -d inhibits top-level logging.
12645 * doc/autoconf.texi (testsuite Invocation): Document that -d only
12646 inhibits top-level logging; debug scripts are created.
12648 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
12650 * tests/autotest.at (Empty test, Empty check): New test to check it.
12652 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
12655 2006-04-10 Stepan Kasal <kasal@ucw.cz>
12657 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
12658 the files if a problem appears. Make the empty *.at files
12659 read-only, too. Proposed by Ralf Wildenhues.
12661 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12663 * config/Makefile.am: Add comment to force updated Makefile.in.
12665 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
12666 space only patch to this file, this patch causes the Makefile.in
12667 files that include freeze.mk to be updated, and thus have a
12668 newer time stamp again, which in turn makes a pristine CVS
12669 checkout have correct time stamps.
12671 * Makefile.maint (cvs-sv): New macro, to be used..
12672 (config.guess-url_prefix, config.sub-url_prefix)
12673 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
12674 point to CVS text checkout of Gnulib files.
12675 (copyright-check): Bump current year.
12676 (announcement): Do not hard-wire `./announce-gen'.
12677 (cvs-update): Propagate failures of `cvs' and `move-if-change'
12679 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
12681 (wget_files): Update config.guess, config.sub, texinfo.tex by
12682 `wget-update', now that their URLs work again.
12684 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
12686 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
12687 Problem noted by Paul D. Smith.
12689 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12691 * doc/autoconf.texi: Remove unused words from word list.
12692 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
12693 .x-sc_trailing_space: New files.
12695 * doc/standards.texi: Sync from gnulib.
12697 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
12698 `LIBOBJDIR' as experimental.
12700 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
12701 with a target directory; it's internally implemented as `cp'
12702 anyway, but since Autoconf advertises the possibility to use
12703 a target directory when LN_S is `ln -s', we need to find out.
12704 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
12705 analyzed by Keith Marshall <keith.marshall@total.com>.
12709 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
12711 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
12712 confdefs.h as-is. In general, if it has backslash-newline or the
12713 like, then it doesn't work either to sort or to remove empty
12716 2006-04-09 Stepan Kasal <kasal@ucw.cz>
12718 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
12720 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
12722 * lib/autom4te.in (Automake-preselections): Preselect
12725 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
12727 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
12728 apostrophe within a single-quoted string, as this is the usual
12729 tradition and is easier to read than '"'"'. Don't rely on the
12730 shell treating "$/" like '$/'. Use a more-consistent indenting
12731 style for the trap.
12733 2006-04-09 Eric Blake <ebb9@byu.net>
12735 * tests/autotest.at (Backquote command substitution),
12736 (Multiline backquote command substitution): Remove mistaken
12737 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
12739 (Parenthetical command substitution, Multiline parenthetical
12740 command substitution): here.
12742 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
12744 Import macros from gnulib (often changing their name).
12746 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

12766 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
12767 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

12771 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
12772 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
12773 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
12774 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
12775 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
12776 (C Compiler): Move AC_C_LONG_DOUBLE to ...
12777 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
12778 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
12779 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
12780 (Coding Style). Don't mention m4_expand_once.
12781 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

12789 (AC_HEADER_ASSERT): New macro.
12790 (AC_HEADER_STDBOOL): Don't assume "#error" works.
12791 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
12792 Catch a bug in an HP-UX C compiler.
12793 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
12794 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

12801 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
12802 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
12804 2006-04-08 Stepan Kasal <kasal@ucw.cz>
12806 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
12807 of the warning introduced by the 2001-08-28 change.
12809 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
12810 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12812 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
12813 variables shall be overriden by the cache.
12814 * tests/torture.at (AC_ARG_VAR): Test also with a first value
12815 that contains braces.
12817 2006-04-07 Stepan Kasal <kasal@ucw.cz>
12819 Revert the patch from 2006-04-01 and only improve
12820 _AS_DETECT_BETTER_SHELL:
12822 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
12823 skip nonexistent directories.
12824 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
12825 only shell candidates which exist.
12826 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
12827 * lib/autotest/general.m4 (AT_INIT): No need to give three
12828 parameters to _AS_PATH_WALK.
12830 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
12831 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12833 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
12834 distinguish m4sugar macros.
12835 * tests/tools.at (autoupdating with aclocal and m4_include):
12836 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
12837 test case by Noah Misch <noah@cs.caltech.edu>.
12839 2006-04-07 Stepan Kasal <kasal@ucw.cz>
12841 Revert my change from 2006-03-17, in other words:
12842 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
12844 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
12845 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
12848 2006-04-07 Eric Blake <ebb9@byu.net>
12850 * doc/autoconf.texi (Programming in M4sh): Document that
12851 AS_MKDIR_P exits the script on failure.
12852 * lib/autotest/general.m4: Remove redundant AS_ERROR.
12854 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12856 * config/elisp-comp, config/install-sh, config/mdate-sh,
12857 config/missing, config/mkinstalldirs: Sync from Automake.
12859 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
12862 * doc/make-stds.texi: Sync from gnulib.

12866 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
12867 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
12870 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
12871 Eric Blake <ebb9@byu.net>,
12872 Paul Eggert <eggert@cs.ucla.edu>,
12873 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12875 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
12876 whether `set' quotes correctly: redirect stderr of the tested
12877 `set', and use a subshell, for Ultrix; use `sed' instead of
12878 `grep' for zsh `set' which may write binary output; match only
12879 at the beginning of a line, to avoid false positives.
12880 In order to avoid false positives by unrelated variables with
12881 multiline content, put the dump algorithm in a subshell and
12882 unset all variables containing newlines (except some which are
12883 special to the shell). Warn about cache variables that are
12886 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12888 * config/config.guess, config/config.sub, config/texinfo.tex:
12889 Sync from upstream.
12891 * tests/mktests.sh: Reword comments.
12893 * tests/mktests.sh: Only skip internal macros starting with
12894 `_AC_' or `__AC_'. Noted by Stepan Kasal.
12895 Update exclusion lists for the test suite to this end:
12896 (AC_ARG_VAR): Do test this now.
12897 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
12898 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
12899 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
12900 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
12902 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
12903 shell issue with double-quoted command substitutions of native
12905 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
12908 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

12914 (m4-check): Likewise.
12915 (sc_system_h_headers): Do not print rule on execution.
12916 (sc_tight_scope): Do not fail for non-existing `src' directory.
12917 (sc_changelog): Skip the Copyright footer.
12918 * lib/autoconf/lang.m4: Remove trailing space.
12920 * lib/autoconf/status.m4: More replacements to
12921 <tab><space> where this makes sense.
12923 2006-04-06 Stepan Kasal <kasal@ucw.cz>
12925 * tests/Makefile.am (maintainer-check-posix):
12926 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
12928 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
12929 ac_config_<foo>s again, sometimes normalized, sometimes not.
12930 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
12931 (AC_CONFIG_COMMANDS): Do not do so here.
12932 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
12933 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
12934 2005-07-25 rewrite. Noticed by Noah Misch.
12936 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
12937 _AC_PRESERVE_HELP_ORDER, ...
12938 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
12940 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
12941 inside m4_expand_once; it is redundant.
12943 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
12944 for --help from Cygnus `configure.'
12946 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
12948 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
12949 on a patch proposed by Ralf Wildenhues.
12951 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
12953 * lib/autoconf/status.m4: Replace <space>''<tab> with
12954 <tab><space> where this makes sense.
12956 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
12957 Noah Misch <noah@cs.caltech.edu>
12959 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
12960 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
12961 * doc/autoconf.texi (Help Formatting): New node.
12962 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
12964 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12966 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
12967 lib/autoconf/specific.m4, lib/autoconf/status.m4,
12968 lib/autoconf/types.m4, lib/autotest/general.m4,
12969 tests/mktests.sh, tests/torture.at: White space cleanup:
12970 remove some SPACE before TAB, or add quoting ('' or @&t@).
12972 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
12974 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
12976 2006-04-05 Eric Blake <ebb9@byu.net>
12978 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
12979 empty test suite works.
12980 * tests/autotest.at (Empty test suite): Remove xfail.
12982 2006-04-05 Noah Misch <noah@cs.caltech.edu>
12984 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
12985 TAGS to ac_config_<foo>s.
12986 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
12987 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
12988 normalizing it, consistent it with previous releases.
12989 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
12991 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
12993 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
12994 Use simplified args that Eric Blake originally suggested.
12996 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
12998 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
12999 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
13000 Use 'comm' rather than N instances of grep; this also fixes a bug
13001 whereby substrings were incorrectly matched, causing us to not

13003 (exclude_list): Exclude empty macros.
13004 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

13910 in case the computer is too quick. Double quote the configure.ac
13913 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
13914 problems if the testsuite were running too fast.
13916 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
13918 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
13919 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
13920 (which belong to Xt, not X itself). See Debian bug 327655.
13921 * NEWS: Mention this.
13923 2005-09-07 Stepan Kasal <kasal@ucw.cz>
13925 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
13927 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
13929 * config/move-if-change: Don't output "$2 is unchanged";
13930 suggested by Ben Elliston. Handle weird characters correctly.
13932 2005-09-06 Stepan Kasal <kasal@ucw.cz>
13934 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
13935 calls, so that the final expansion of this macro is shorter.
13936 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
13937 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
13938 the cleanup there. Use AS_VAR_* macros, to be more general.
13939 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
13941 * lib/autoconf/general.m4: Use AS_IF where appropriate.
13943 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
13945 2005-09-01 Stepan Kasal <kasal@ucw.cz>
13947 * doc/autoconf.texi (Configuration Headers): Add an index entry
13950 2005-08-26 Pavel Roskin <proski@gnu.org>
13952 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
13953 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
13956 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
13958 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13959 The previous patch didn't work, so try a better one.
13961 2005-08-26 Stepan Kasal <kasal@ucw.cz>
13963 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
13964 in the example. Reported by Bruno Haible.
13965 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
13966 "if $undefined_var;" succeeds with my shell.
13968 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
13969 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
13970 but change the m4_divert_text to m4_divert_once.
13972 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
13974 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13975 Work around bug in Solaris /usr/xpg4/bin/awk.
13976 The bug is present in at least Solaris 8 through 10.
13978 2005-08-24 Stepan Kasal <kasal@ucw.cz>
13980 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
13981 some evil values and relying on the fact that $* concatenates the
13982 parameters by the first character from IFS.
13984 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
13985 Stepan Kasal <kasal@ucw.cz>
13987 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
13988 first header appears, define AH_HEADER.
13989 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
13990 Update limitations about when to call AC_CONFIG_HEADERS.
13991 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
13992 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
13993 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
13994 ``Configuration Actions''; fix their index entries.
13996 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
13997 options correctly. Process N-M as M-N if M is smaller than N.
13998 Process ranges correctly so that N-N will run only N.
13999 Sort and uniquify the tests that will be run. If there is more
14000 than one test, reinsert the banners for the tests.
14001 * tests/autotest.at (Keywords): Unmark XFAIL.
14003 2005-08-23 Stepan Kasal <kasal@ucw.cz>
14005 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
14006 before passing the macro name to AH_TEMPLATE.
14008 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
14009 now opens log after option processing; in particular, --version
14010 and --help do not touch config.log.
14012 * Makefile.maint: Revert the change from 2005-08-12.
14014 2005-08-22 Stepan Kasal <kasal@ucw.cz>
14016 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
14018 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

14022 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
14023 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
14026 * doc/autoconf.texi (Defining Symbols, Changed Results):
14027 Prepend to LIBS, not append, in examples.
14029 2005-08-16 Stepan Kasal <kasal@ucw.cz>
14031 When building in place, set srcdir="."; suggested by Tim Van Holder.
14033 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
14034 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
14035 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
14036 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
14037 does not mean "no --srcdir option".
14039 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14041 * tests/autoscan.at (autoscan): New file.
14042 * tests/suite.at: Use it.
14043 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
14044 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
14046 * tests/autotest.at (Keywords): Test keywords combinations.
14048 2005-08-12 Stepan Kasal <kasal@ucw.cz>
14050 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
14051 add "2>&1"; gzip 1.2.4 prints help on stderr.
14053 2005-07-27 Stepan Kasal <kasal@ucw.cz>
14055 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
14056 was pushdef'ed twice while popped only once. Push it only once.
14057 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
14059 2005-07-26 Stepan Kasal <kasal@ucw.cz>
14061 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

14066 * Makefile.maint: Update from Bison.
14068 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
14069 "<tab>" in comment, so that the point is understandable.
14071 2005-07-25 Stepan Kasal <kasal@ucw.cz>
14073 Rewrite substantial part of lib/autoconf/status.m4.
14074 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
14075 and CONFIG_COMMANDS are not processed in four separate loops.
14076 Instead, there is one main loop. This alows that the common code
14077 is expanded only once, thus config.status (and configure) is smaller.
14079 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
14080 the AC_LIST_FILES and cousins macros are no longer used.
14082 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
14083 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
14084 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
14085 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
14086 contain the initialization, nor the for loop, nor the associated
14087 commands; all these go to ...
14088 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
14089 _AC_OUTPUT_CONFIG_STATUS.
14090 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
14091 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
14092 (_AC_OUTPUT_FILE): The creation of the sed script ...
14093 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
14094 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
14095 _AC_OUTPUT_MAIN_LOOP.
14096 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
14097 _AC_CONFIG_COMMANDS): Use ...
14098 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
14099 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
14100 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
14101 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
14102 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
14103 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
14105 (_AC_CONFIG_UNIQUE): Update.
14106 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
14107 Replaced by this ...
14108 (_AC_LIST_TAGS): ... new common macro.
14109 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
14110 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
14111 (_AC_LIST_TAG_COMMANDS): ... new common macro.
14112 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
14113 this didn't belong to the `config commands' section.
14114 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
14115 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
14116 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
14117 to the `config commands' section either.
14118 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
14119 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
14121 ... and many changes to the comments nearby.
14123 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
14124 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
14125 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
14126 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
14127 (#define header templates): The comment at the top of the generated
14128 header now includes the name(s) of the source file(s).
14130 Several unrelated small changes:
14132 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
14133 parameter to AC_DIAGNOSE.
14134 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
14135 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
14136 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
14137 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
14138 with AU::AC_OUTPUT.
14139 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
14140 in AC_OUTPUT doesn't double-quote it either.
14141 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
14144 2005-07-10 Stepan Kasal <kasal@ucw.cz>
14146 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
14147 versions of Portland Group compiler produce single- and double-quoted
14148 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
14149 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
14151 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
14153 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
14154 This is a corrected version of yesterday's patch.
14156 2005-07-07 Stepan Kasal <kasal@ucw.cz>
14158 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
14159 path, too; insert a "===" to emphasize the line.
14161 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
14162 ac_cv_build_alias to ac_build_alias.
14163 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
14165 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
14166 change eliminates it. Problem reported by Alexandre Duret-Lutz.
14167 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
14168 (AC_ARG_VAR): ... here.
14169 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
14172 Keep a list of all precious variables and process them with one simple
14173 for loop, instead of expanding all commands, or, OTOH, complicated
14174 processing of output of "set".
14175 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
14176 variable names in new macro...
14177 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
14178 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
14179 a loop to assign all ac_env_* and ac_cv_env_* variables.
14180 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
14182 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
14183 its value to shell variable ac_precious_vars and call
14184 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
14185 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
14186 _AC_ARG_VAR_VALIDATE.
14188 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
14189 and the AC_SUBSTs ...

14200 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.
14201 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.

14207 They are generated by the Tru64 v5.1B shell.
14209 2005-07-05 Stepan Kasal <kasal@ucw.cz>
14211 Fix my changes from 2005-07-01; reported by Noah Misch.
14212 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
14213 description, the macro now accepts only a single tag.
14214 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
14216 Fix cases when the varsions of Autoconf and Autotest don't match.
14217 Reported by Noah Misch.
14218 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
14219 at_top_builddir, for compatibility with older autotest.
14220 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
14221 is not set, use at_top_builddir, for compatibility with older
14222 versions of autoconf.
14224 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
14226 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
14227 Problem reported by Patrick Welche.
14229 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
14231 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
14232 sed substitution command, so that we allow | in program prefixes
14233 and program suffixes. (& is a problem anyway; we're not fixing
14235 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
14236 configure_input, top_builddir, srcdir, etc.
14237 * lib/autotest/general.m4 (AT_INIT): Likewise, for
14238 PATH_SEPARATOR in AUTOTEST_PATH.
14240 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
14242 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
14243 for loop over config.site files using `set', to allow
14244 directory names containing IFS characters.
14246 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
14248 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
14249 directories with weird names. Apparently some people like living
14250 on the edge. However, improve the test that "pwd" actually does
14251 report a name for the working directory.
14252 * NEWS: Remove the claim that we test for funny chars in dir names.
14254 2005-07-01 Stepan Kasal <kasal@ucw.cz>
14256 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
14258 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
14259 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):

14266 about #include <config.h>.
14267 (Generic Functions): Mention the Gnulib project.
14268 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
14270 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
14271 document to output the default config_* lists to config.status.
14272 Don't recognize option --file, if the functionality is not there.
14273 Likewise for --header; moreover, recognize --he and --h as shortcuts
14274 for --help in that case.
14276 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
14277 matches the order of execution. No code changed.
14279 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14281 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
14282 single-quoted -cmdline argument in Portland Group compiler.
14283 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.

14287 * lib/autom4te.in (Automake-preselections): Preselect AC_SUBST_TRACE.
14289 2005-06-29 Stepan Kasal <kasal@ucw.cz>
14291 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
14292 descriptors to child processes; reported by Norman Gray.
14294 2005-06-29 Stepan Kasal <kasal@ucw.cz>
14296 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
14298 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
14299 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
14300 (AC_SUBST): Call it.
14301 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
14302 the directory specific variables; but don't call it for configure_input.
14304 2005-06-28 Derek Price <derek@ximbiot.com>
14306 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
14309 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
14311 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
14312 directory have inherent problems with special characters like spaces,
14313 due to limitations in Make syntax. Problem reported by Alexandre
14315 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
14316 Also, fix Tru64 porting problem with shell patterns,
14317 reported by Ralf Wildenhues.

14327 Fix some more shell quoting problems. Prompted by a bug report
14328 from Justace Clutter.
14329 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
14330 variable into diagnostic. Make the diagnostic an error, not a warning,
14331 because we really don't support spaces and suchlike in dir names.
14332 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
14333 Don't worry about backslashes in srcdir; it can't happen now.
14334 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
14335 Simplify ac_optarg handling.
14336 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

14343 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
14344 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
14346 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
14347 that '\|' is not allowed in BREs; recommend using newline separated
14348 list of patterns instead of multiple -e options.

14356 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
14358 2005-06-21 Stepan Kasal <kasal@ucw.cz>
14360 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
14361 b, t, r, w commands require single space, while : cannot have any.
14362 (Special Shell Variables): Fix sed code this in the example.
14363 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
14364 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
14366 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
14367 expand to the empty list. Don't use two pairs of m4_changequote,
14368 it's not necessary.
14370 2005-06-20 Derek Price <derek@ximbiot.com>
14372 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
14374 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
14376 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
14377 * doc/autoconf.texi:
14378 Don't mention Solaris versions so much, if a
14379 problem is common to all extant versions of Solaris. Say "SunOS
14380 4" instead of "SunOS" for SunOS 4.
14381 (awk): Mention more of the limitations of traditional Awk.
14382 (cat): Don't talk about cat -v.
14384 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
14386 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
14387 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
14388 but the implementation is entirely different and is designed
14389 to be compatible with glibc strverscmp.
14390 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
14392 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
14393 on Mac OS X 10.4 reported by Peter O'Gorman in:
14394 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
14395 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
14396 Use shell builtins rather than 'expr', to work around expr bug.
14398 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
14400 * doc/autoconf.texi: "filesystem" -> "file system".
14401 "behaviour" -> "behavior".

14406 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
14407 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
14409 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
14410 (.x.1): Ignore the time stamp in the .TH line when deciding whether
14411 to update the man page. That way, we don't have to check in new
14412 man pages every month.
14414 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
14415 quotes and backslashes. Patch from Derek Price.

14424 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
14425 -u, since it outputs chatter if the input files are the same.
14426 Problem reported by Ralf Menzel.
14428 2005-06-08 Derek Price <derek@ximbiot.com>
14430 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
14431 renaming them since they are about to be redefined anyhow.
14433 2005-06-08 Derek Price <derek@ximbiot.com>
14435 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
14436 redefined M4 macros to this node. Document m4_include & m4_sinclude.
14437 Move m4_undefine to alphabetical order.
14439 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
14441 * README: Recommend GNU M4 1.4.3 or later.
14442 * doc/autoconf.texi (Introduction): Likewise.
14443 Reword to avoid some formatting glitches.
14444 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
14445 Clarify explanation of HP compiler bug.
14446 Redo example output tp match current CVS snapshot.
14447 Use @example.org in email addresses when the examples
14448 might get inadvertently cut-and-pasted into user code.
14449 Remove example of autom4te usage that doesn't seem to work now.
14450 Use modern AC_INIT (except when the example is meant to be
14451 shown with Autoconf 2.13).
14452 Update ksh info for Solaris 9 and later.
14454 Modernize description of Automake versions a bit.
14455 Don't claim a future version of Autoconf is near.
14456 * doc/install.texi: Reword to avoid some formatting glitches.
14458 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14460 * doc/autoconf.texi: Add [] to examples, so that the manual
14461 follows its own advice about quoting better.
14462 Reword to avoid some formatting glitches.
14463 * doc/installt.exi: Reword to avoid some formatting glitches.
14465 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
14466 Tru64 ksh pattern matching bug. Reported against Libtool by
14467 Albert Chin <libtool@mlists.thewrittenword.com> and
14468 Nicolas Joly <njoly@pasteur.fr>.
14470 2005-06-06 Stepan Kasal <kasal@ucw.cz>
14472 m4_cdr of one-member list was [[]] (one-member list containing an
14473 empty string) instead of [] (an empty list. Callers were skewed to
14474 match this misbehaviour. As a consequence of this:
14475 - m4_foreach([x], [], [foo]) expanded to `foo', while
14476 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
14477 This bug has been fixed:
14479 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
14480 expand to an empty string; print error msg if called without
14482 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
14483 misbehaviour; handle [] and [[]] correctly.
14485 2005-06-06 Stepan Kasal <kasal@ucw.cz>
14487 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
14488 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
14489 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
14491 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
14493 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
14494 swallow records with more than 99 fields.
14495 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
14496 parse the long line.
14498 2005-06-04 Stepan Kasal <kasal@ucw.cz>
14500 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
14501 swallow literals longer than 399. Reported by Ralf Wildenhues.
14502 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
14503 to workaround this limitation.
14505 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
14507 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
14508 to gfortran, and make these the first two compiler names
14509 checked (following the general autoconf preference for gcc).
14511 2005-06-03 Stepan Kasal <kasal@ucw.cz>
14513 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
14514 (DISTCLEANFILES): Remove $(check_SCRIPTS).
14515 (testsuite): Make sure autotest.m4f is up-to-date before using it.
14517 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
14519 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
14520 expression of unbounded size when processing the --list
14521 option. This runs afoul of a limit of 399 bytes per regular
14522 expression on AIX. Problem reported by Ralf Wildenhues.
14524 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
14526 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
14527 * doc/autoconf.texi (Particular Headers): Reword example
14528 for multiline stdbool replacement.
14529 (Setting Output Variables): Reword text a bit. Don't
14530 give all the details about |#_!!_#|.
14531 Reword description of line replacement.
14533 2005-05-31 Dan Manthey <dan_manthey@partech.com>
14535 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
14536 now contain newlines, and substituted files must be referenced on
14537 a line alone; the sed scripts to substitute them are now very
14539 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
14540 commands can be put in a sed script portably.
14541 * doc/autoconf.texi (Setting Output Variables): Document above
14542 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
14543 use of multiline substitution.
14544 * tests/torture.at: No longer expect substitution of newline to fail.

14553 * tests/local.at: Don't attempt to check for negated character
14554 classes in shell scripts. The test was too brittle.
14556 2005-05-25 Stepan Kasal <kasal@ucw.cz>
14558 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
14559 * doc/autoconf.texi (Limitations of Builtins): Document this
14562 2005-05-24 Stepan Kasal <kasal@ucw.cz>
14564 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
14565 common code; used in many places in the tree.

14567 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
14569 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
14571 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
14572 messages when ac_unique_file is not found.
14573 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
14574 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
14575 commands, for consistency with AC_MSG_ERROR and such.
14577 * bin/autoconf.as: Make more use of "shift 2" in option processing.
14579 * bin/Makefile.am: Merge the two rules for creating scripts.

14587 2005-05-20 Stepan Kasal <kasal@ucw.cz>
14589 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
14590 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
14591 (ac_top_builddir): ... this ...
14592 (ac_top_build_prefix): ... to this; the old name is also kept, for
14593 backward compatibility.
14594 (ac_top_builddir_sub): New variable, without the trailing slash,
14596 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
14597 * doc/autoconf.texi (Configuration Actions): Rename
14598 ac_top_builddir to ac_top_build_prefix.
14599 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

14610 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
14611 argument to m4_foreach. I guess it was necessary in the past,
14612 but I think it's a no-op now.
14614 2005-05-17 Stepan Kasal <kasal@ucw.cz>
14616 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
14617 ``cat <<_ACEOF'' commands to one.
14618 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
14619 * lib/autoconf/status.m4: On various places, use expr instead of
14621 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
14622 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
14623 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
14625 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
14626 the wrong patterns between ``case'' and ``esac.'' The previous
14627 code had false positives.
14629 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
14631 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

14696 quoting rules. Problems noted by Stepan Kasal.
14697 Also, throughout this document, be more careful about white space.
14698 "blank", "white space", and "space" all have different meanings
14699 and we should be careful to say what we mean.
14701 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
14703 Fix C++ related problems reported by Werner Lemberg.
14704 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

14749 processed correctly in AS_HELP_STRING; avoid this in the examples.
14750 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
14751 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
14752 comment and reduce m4_default([foo], []) to [foo].
14753 (m4_strip): Update the explanation.
14755 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
14757 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

14759 Problem reported by Jennis Pruett.
14760 * lib/autoconf/functions.m4
14761 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
14762 Don't bother to remove core files; AC_RUN_IFELSE should do that

14809 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
14810 Merge `-z option' as well for the benefit of Solaris link flags. Pass
14811 whole-archive (-zallextract, -zdefaultextract) options in the hope of
14812 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported

14818 a directory whose name contains a special character like space,

14835 ac_pwd, and quote srcdir.
14836 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
14838 * doc/autoconf.texi: Fix some systematic formatting problems.
14839 ".)" needs a following @: if not at the end of a sentence, and
14840 similarly for "!)". "etc." should be preceded by a comma.
14841 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.

14845 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

14857 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
14858 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
14859 from a Common Lisp's `cl'.
14860 (AC_PROG_CXX): Behave according to the documentation: don't
14861 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
14862 make the variable CCC precious; use `cl.exe', not `cl'.

14865 Alexandre Duret-Lutz <adl@gnu.org>
14867 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
14868 /dev/null, as "configure" shouldn't read stdin, and this insulates
14869 us from problems (e.g., when testing for "cl"). Also, do this
14870 redirection before invoking "hostname" or "uname", and keep the
14871 original input stream available via...
14872 (AS_ORIGINAL_STDIN_FD): ... this new macro.
14873 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

14885 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
14886 newline if neither \c nor -n work, as that would output two
14887 newlines. Prefer -n to \c. Reported by Stepan Kasal.

14891 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

14897 Undo previous change, except keep the change to
14898 lib/autoconf/programs.m4 that replaced grep with shell
14899 pattern-matching. This is because net-snmp configure reads stdin.
14900 Reported by Noah Misch.

14904 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
14905 from /dev/null, as "configure" shouldn't read stdin, and this
14906 insulates us from problems (e.g., when testing for "cl").
14907 Suggested by Alexandre Duret-Lutz. Also, do this redirection
14908 before invoking "hostname" or "uname".
14909 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14910 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.

14914 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
14915 Also, replace grep with shell pattern-matching, to save a process.

14941 Don't recommend PATH_SEPARATOR=';' so strongly.
14942 Mention that $RANDOM might expand to the empty string.
14943 "symlink" and "soft link" -> "symbolic link".

15083 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
15084 Update the long comment explaining it.
15086 m4_require no longer writes an ``is required by'' line to the
15087 execution stack. It contains only one bit of non-redundant
15088 information: that the macro was required, not called. And even
15089 this bit is useless in most situations: have you ever met a macro
15090 which both calls and requires the same macro?
15092 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
15093 (_m4_defun_pro_outer): ... only via this macro, for the outermost

15140 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
15141 Warn about newline stripping in `` and $(). Update Solaris
15143 (Limitations of Builtins): Use expr "X...", not expr "x...", as

15194 (_m4_divert_n_stack): New macro; the expansion is
15195 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
15197 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
15198 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
15199 stored in _m4_divert_diversion or _m4_divert_dump.
15200 (m4_divert_pop): When the parameter is given, compare the symbolic
15201 name with the last diversion pushed on the stack. Previously, the
15202 current diversion was compared with the numeric value of the
15203 diversion given as the parameter.
15204 (m4_require): If the macro hasn't been expanded yet, call ...

15512 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
15513 "char c = '\200';" rather than "char c = 0x80;" as the

15694 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
15695 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
15696 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
15697 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
15699 More fixes to support spaces in the name of the build directory.
15700 This isn't a complete fix but it's an improvement.
15702 * bin/autoconf.as (autom4te_options): New var.
15703 Use it instead of appending to AUTOM4TE, so that we can allow
15704 spaces in the build directory's absolute name.
15705 * bin/autoheader.in ($autoconf): Allow spaces in file names.

15759 useful for pkdsh, too.
15761 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
15763 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
15764 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
15765 Don't fail if ENV or BASH_ENV is readonly.
15766 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
15767 etc. are read only. Problem reported by Ludovic Courtes.
15769 2004-06-23 Noah Misch <noah@cs.caltech.edu>

15777 * doc/autoconf.texi (File System Conventions): Warn about
15778 names like "aux". Problem reported by Eric Blake.
15780 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
15781 by zero instead of array size, so that we can use any arithmetic
15782 constant expression (instead of requiring an integer constant
15783 expression). This allows us to test expressions like DBL_MAX <
15784 LDBL_MAX, which didn't conform to the C standard using the old
15786 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
15787 now that we can do floating-point tests at compile time.
15789 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
15791 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
15792 and LDBL_EPSILON, as the resulting expression isn't an
15793 integer constant expression and violates the C standard.
15794 Problem reported by Nelson H. F. Beebe. Also, check
15795 for "L" suffix, and check that long double doesn't have
15796 worse range or precision than double, that mixed-mode
15797 arithmetic doesn't generate a diagnostic, that double
15798 constants fit in long double.

15827 change). Patch reported by Ralf Wildenhues in
15828 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
15830 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
15831 function F exists if the compiler and linker let you compile an
15832 expression like (F != 0). Recent versions of GCC optimize away
15833 the reference to F in that case, since every function address must
15834 be nonzero, so the link succeeds even if F does not exist.
15835 Problem reported by Manu in
15836 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.

15850 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
15851 referencing AC_FUNC_STRERROR_R.
15853 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
15854 note pessimistic assumption when cross compiling.
15856 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
15858 * doc/autoconf.texi (Limitations of Make): Note that BSD make
15859 (until 2004) invoked subcommands with sh -e, contra POSIX.
15860 Reported by Kevin Ryde.
15862 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
15864 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
15865 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
15866 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
15867 `test -f " /usr/bin/grep"', which _always_ failed.
15868 (AC_PROG_SED): Ditto bogus PATH fix.
15869 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
15870 requires that grep correctly supports _multiple_ `-e' options, rather
15871 than stating only that grep should accept `-e'.
15873 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
15875 Port to C99, which requires that 'exit' be declared.
15877 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
15878 to ensure that stdlib.h is included.
15879 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
15880 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
15881 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
15882 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
15883 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
15884 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
15885 when using 'exit' in a test; C99 requires that 'exit' be declared.
15887 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
15889 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
15890 now prefers 'grep' implementations that accept -e.
15891 (Limitations of Usual Tools): Describe problems of traditional
15892 egrep and fgrep with long input lines, and of traditional grep
15894 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
15895 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
15896 All callers changed. Append /usr/xpg4/bin to the PATH, for
15898 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
15899 the user with complaints about multiple -e options.
15900 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
15901 Define it with AC_PROG_GREP.
15902 * configure.ac (AC_PROG_GREP): Add.
15903 * lib/freeze.mk (GREP): New macro.
15905 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
15907 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
15908 a possible candidate only after all others fail, rather than
15909 consulting it first. This improves backward compatibility by
15910 better reflecting the way shell selection occurred in previous
15911 versions of Autoconf, and should help to avoid triggering latent
15912 problems in other packages, such as the one in Automake where zsh
15913 is not handled robustly:
15914 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
15915 Although it is not Autoconf's responsibility to work around
15916 problems in Automake, it nevertheless makes sense to avoid
15917 introducing unnecessary incompatibilites.
15919 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
15920 Gary V. Vaughan <gary@gnu.org>
15922 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
15923 how deeply nested we are when a suitable tool is found, set the
15924 ac_path_TOOL_found flag.
15925 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
15926 nested we are in this macro. Break out of all 3 nested loops if
15927 ac_path_TOOL_found is set.
15929 2004-04-21 Gary V. Vaughan <gary@gnu.org>
15931 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
15932 of the _AS_PATH_WALK loop too if GNU flavor is found.
15934 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
15936 * doc/autoconf.texi (Limitations of Make): Update documentation
15937 for `$<'. New entry `Long lines', based on a report from Simon
15938 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
15939 paragraph about DJGPP, based on a mail from Richard Dawe.
15941 2004-04-20 Paul Eggert <eggert@twinsun.com>
15943 * tests/c.at (C keywords): Don't assume that GCC supports
15944 "restrict" and "inline", as sufficiently-old GCC versions do not
15945 (also, GCC configured to be in pedantic C89 mode does not).
15946 Problem reported by Sumit Pandya in:
15947 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
15949 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
15950 consider -g to work if it generates warnings when plain compiles
15951 don't. Problem reported by Braden McDaniel in:
15952 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

15955 reported by Jim Meyering in:
15956 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
15958 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
15959 linker output files before linking, to work around IRIX 6 linker bug.
15960 Problem reported by Rainer Orth in:

15963 2004-04-20 Gary V. Vaughan <gary@gnu.org>
15965 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
15966 best tool so far counter rely on the tool path variable name to
15967 avoid checks for one tool being affected by the results of running
15968 the length check on a previous tool.
15970 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
15971 match expression argument, as different greps have different
15972 regular expression flavours.
15973 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
15975 (AC_PROG_EGREP): Pass 'EGREP$'.
15976 (AC_PROG_GREP): Pass 'GREP$'.
15978 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
15980 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
15981 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
15983 2004-03-29 Paul Eggert <eggert@twinsun.com>
15985 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
15986 Types, Specific Compiler Characteristics, System Services,
15987 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
15988 etc. consistently instead of 'long', 'short', 'unsigned' etc.
15989 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

16003 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
16004 now defines HAVE_DECL_TZNAME if it is declared, when
16005 HAVE_STRUCT_TM_TM_ZONE is not defined.
16006 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
16007 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
16010 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
16012 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
16013 superfluous backslashing of quotes (") in sed expressions;
16014 thanks to Paul Eggert.
16016 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
16018 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
16019 Fortran compiler is ifort, also added pghpf; thanks to Nelson
16020 H. F. Beebe for the bug report.
16022 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
16024 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for

16065 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
16066 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
16067 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
16069 (AC_CHECK_ALIGNOF): New macro.
16070 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

16074 2004-03-03 Paul Eggert <eggert@twinsun.com>
16076 * bin/Makefile.am (edit): Don't use $< in a context where
16077 POSIX doesn't require support for it. Use $@.in instead.
16078 Problem reported by Anthony N. Frasso in
16079 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

16108 AC_SUBST provides no portable way to escape literal newlines.
16110 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
16111 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
16112 Darwin uses -lcrt2.o and there's little point to cataloging all

16138 Eric Sunshine <sunshine@sunshineco.com>
16139 Paul Eggert <eggert@twinsun.com>
16141 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
16142 (AS_INIT): Output shell initialization there. Removed optional
16143 parameter. Expand _AS_SHELL_FN_SPY.

16152 (_AS_RUN): Move it here, support testing with eval.
16153 (AS_REQUIRE_SHELL_FN): Require shell functions when
16155 (_AS_LINENO_WORKS): Put around braces, we do not

16168 macros with AU_DEFINE.
16169 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
16170 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

16173 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

16189 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

16191 the 2003-05-22 change, which removed the older years from the list.
16192 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
16194 2004-01-27 Gary V. Vaughan <gary@gnu.org>

16203 egrep and fgrep respectively if $GREP -E/-F don't work.
16204 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
16205 _AC_PROG_GREP, and AC_PROG_SED.
16206 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
16207 longest input length accepted by a command.

16209 * doc/autoconf.texi (Particular Programs): Document the changes.
16212 2004-01-27 Paul Eggert <eggert@twinsun.com>
16214 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
16215 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
16216 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
16217 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
16219 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
16220 bin/autoconf.in, config/Makefile.in, config/config.guess,
16221 config/config.sub, config/install-sh, config/mdate-sh,

16238 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
16239 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
16240 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
16241 not <inttypes.h>. Problem reported by Tim Mooney in
16242 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
16243 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
16246 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
16247 otherwise "make check" fails because it forbids cmp (I guess
16248 because cmp treats files as binary on DOS-like systems).
16250 * tests/mktests.sh: Update copyright date to 2004, since some tests
16251 have changed in 2004.
16253 2004-01-23 Gary V. Vaughan <gary@gnu.org>
16255 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
16256 non-truncating sed or gsed program in PATH.
16257 * tests/acprograms.at: Add it.
16258 * doc/autoconf.texi (Particular Programs): Document it.
16261 2004-01-15 Paul Eggert <eggert@twinsun.com>
16263 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
16264 -std1 disables some useful extensions on Tru64. Problem reported
16265 by N. Lichtmaier in
16266 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
16268 2004-01-14 Paul Eggert <eggert@twinsun.com>
16270 * doc/autoconf.texi (Programming in M4sh): Document that
16271 AS_MKDIR_P succeeds if the destination is a symbolic link
16272 to an existing directory.
16273 (Limitations of Usual Tools): Note that mkdir -p might not
16274 succeed on symlinks to directories.
16276 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
16278 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
16279 * bin/autoheader.in: Grammar fix in message.
16280 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
16281 Test for dir before calling mkdir -p. (trivial changes)
16283 2004-01-13 Eric Blake <ebb9@byu.net>
16285 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
16286 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
16288 2004-01-10 Jim Meyering <jim@meyering.net>
16290 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
16292 2004-01-09 Paul Eggert <eggert@twinsun.com>
16294 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
16295 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
16296 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
16297 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
16298 AC_COMPILE_IFELSE, since we now assume our caller invokes
16299 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
16300 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
16301 of AC_RUN_IFELSE; this avoids the warning mentioned above.
16302 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
16304 2004-01-07 Paul Eggert <eggert@twinsun.com>
16306 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
16307 `"'...'"`, as it's confusing (and I suspect it may not work on
16308 some platforms). The code was incorrect anyway, as it assumed
16309 that \$ evaluated to itself in that context. Reported by
16310 Alexandre Duret-Lutz.
16312 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
16314 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
16315 and _LT_AC_TAGCONFIG.

16320 example, and add more examples. Reported by Eric Sunshine.

16324 * doc/autoconf.texi (Limitations of Usual Tools):
16325 Remove warning against "rm -fr" introduced yesterday; it
16328 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
16329 autoscan, autoupdate, ifnames): Don't use chmod -w.
16330 * lib/Makefile.am (autom4te.cfg): Likewise.
16331 * doc/autoconf.texi (Limitations of Usual Tools): Warn against

16337 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
16338 by doing lineno substitution only on lines containing "$LINENO".

16342 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
16343 Use "rm -f" to remove conftest.sed, not plain "rm".
16344 Bug reported by David Relson in
16345 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
16347 * Makefile.am (autom4te-update):
16348 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
16349 * Makefile.maint (my-distcheck, do-po-update): Likewise.
16350 * doc/autoconf.texi (Guidelines): Likewise.
16351 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

16357 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
16359 * doc/autoconf.texi (Limitations of Usual Tools):

16364 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
16365 -c -o might not work. From a suggestion by Kevin Ryde.
16366 (C Compiler, Generating Sources, Limitations
16367 of Usual Tools, Limitations of Make, Making testsuite Scripts):
16368 Don't put '-o' after non-options, as POSIX doesn't allow this.
16369 Mention that cc's name might be gcc or c89 or whatever.
16371 2004-01-04 Kevin Ryde <user42@zip.com.au>
16373 * doc/autoconf.texi: Add various further index entries.
16375 2003-12-29 Paul Eggert <eggert@twinsun.com>
16377 * bin/autoreconf.in (autoreconf_current_directory):
16378 Fix typo: mkdir without umask arg.
16380 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
16382 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
16383 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
16384 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
16385 explanation clearer.
16387 2003-12-24 Andreas Schwab <schwab@suse.de>
16389 * doc/autoconf.texi (Default Includes): Fix misspelling of

16396 * tests/atlocal.in: Store the result here.
16397 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

16401 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
16402 * tests/tools.at (Syntax of the shell scripts): Simplify

16421 _AS_LINENO_WORKS, use it to find out if shell
16423 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
16425 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

16472 parameter of AU_DEFUN.

16476 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
16477 the expanded body, consistently with other macros such as AC_USG.
16479 2003-11-17 Paul Eggert <eggert@twinsun.com>
16481 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
16482 into the initial confdefs.h, to work around a bug in NextStep 3.3
16483 patch 3 reported by Eric Sunshine.
16485 2003-11-15 Kevin Ryde <user42@zip.com.au>
16487 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
16488 than $target since the latter is not usual, add guidelines on when to
16489 use or not use the system type.

16493 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
16494 typo misrepaired by an auto-spellcheck.

16666 Problems reported by Eric Sunshine.
16668 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
16670 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
16671 -mGLOB_options_string stuff for Intel ifc, which can cause

16695 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
16696 cache variable instead of $G77 to decide whether to include -O2,
16697 since $G77 is specific to Fortran 77.

16701 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
16702 free" flag. Re-order flags tested into rough order of popularity.
16704 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
16706 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
16707 arguments so that it can be used with syntax identical to
16708 AC_PROG_F77, and so that we can more easily decide to
16709 remove/deprecate the DIALECT optional argument in the future if it
16710 proves troublesome.
16711 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
16712 non-freeform-supporting compilers. Document freeform flags.
16714 2003-10-03 Akim Demaille <akim@epita.fr>

16776 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
16777 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
16778 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
16779 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
16781 2003-09-26 Akim Demaille <akim@epita.fr>
16783 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
16784 directory for AC_CONFIG_COMMANDS' first argument exists.
16785 This makes valid the invocation of _AC_SRCPATH that follows.
16786 Reported by Eric Sunshine.
16787 * doc/autoconf.texi (Configuration Commands): Adjust.
16789 2003-09-26 Akim Demaille <akim@epita.fr>

16810 The test suite are sometimes assigning timings incorrectly.
16811 Reported by Henk Krus.
16812 Diagnosed by Nicolas Joly.
16814 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
16816 Instead of making AT_help a sequence of assignments to grow
16817 $at_help_all, just make AT_help_all be the growing contents of
16818 $at_help_all, and make a single assignment in...
16820 (at_times_skip): Flip the meaning and rename as...
16821 (at_times_p): this.
16822 (AT_INIT): When summarizing the test that ran, remove

16832 (ifnames): chmod -w.
16833 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
16834 executables, not bin/ executables! Otherwise all the magic needed
16835 to find non installed files is turned off. This caused a failure
16836 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
16837 as found in its environment (sent by tests/autoreconf): pointing
16838 to bin/autom4te that could not find its files.
16839 * tests/mktests.sh: Force the replacement of generated files, for
16840 the sake of "mv" program that are interactive when overwriting a

16849 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
16850 Paul Eggert <eggert@twinsun.com>
16852 Trivial change to support GCC's configuration procedure.

16888 willing to edit the output files.
16890 2003-09-10 Akim Demaille <akim@epita.fr>
16892 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
16893 and AC_FC_FREEFORM.
16894 * tests/mktests.sh: Skip AC_FC_SRCEXT.
16895 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

16917 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

16935 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
16937 Add support for newer Fortran dialects. The F77 interface is
16938 unchanged, and continues to support Fortran 77. New FC macros
16939 correspond to all the old F77 macros, with output variables FC,
16940 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
16941 available dialect, but older dialects can be specified. There are
16942 new macros AC_FC_SRCEXT to set the source extension, and
16943 AC_FC_FREEFORM to accept free-form source files.
16945 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

16981 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
16982 are defaulted by AT_CHECK anyway.
16983 Use AT_CHECK_AUTOM4TE.

17048 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
17049 * bin/autom4te.in: Adjust.
17051 2003-08-21 Akim Demaille <akim@epita.fr>
17053 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
17054 (&verbose): Remove.
17055 (&getopt): Adjust the note and verb channels, depending upon
17057 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
17058 * bin/autoupdate.in: Adjust.
17059 Use &verb, not &verbose.
17061 2003-08-21 Akim Demaille <akim@epita.fr>
17063 * bin/autoheader.in (&parse_args): Use &parse_warnings and
17065 ($help): Use Autom4te::ChannelDefs::usage.
17066 * bin/autoscan.in: Use Autom4te::ChannelDefs.
17067 * lib/Autom4te/General.pm: Don't export error: you don't own it.
17069 2003-08-21 Akim Demaille <akim@epita.fr>
17071 First stab at preserving warnings between calls to autom4te,
17072 including when the cache is used.
17074 There are still several issues: (i) there are too many runs of m4
17075 (one for include, one for warnings, and some more), (ii) warnings
17076 spreading on several lines are not handled gracefully, (iii) the
17077 code meant to have the call stack display for errors does not work
17078 (its handling should move from m4 to autom4te).
17080 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
17082 (@preselect): Add m4_warn.
17083 ($exit_status): Remove, use $exit_code.
17084 ($help): Use Autom4te::ChannelDefs::usage.
17085 (&handle_m4): No longer define the m4_warnings.
17086 At each run, extract and report the warnings.
17087 Always cache the result, including if the exit status is on
17088 failure, since if nothing changes, we should result in the same
17089 failure, hence we can use the cache.
17090 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
17091 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
17093 (m4_warn): Redefine as a do-nothing: it is its invocation that
17094 matters, as warnings are now reported via traces.
17095 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
17096 the contents of m4_warn: make it _call_ m4_warn, so that tracing
17097 the latter reveals calls to the former.
17101 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
17103 2003-08-21 Akim Demaille <akim@epita.fr>

17113 (&parse_warnings): Accept a list of warning requests.
17114 (&usage): Return a string, not a side effect.
17115 (cross): New warning category.
17117 2003-08-21 Akim Demaille <akim@epita.fr>
17119 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
17120 (&require_configure_ac): Accept an optional directory argument.
17121 ($configure_ac): Remove.
17122 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
17123 (&catfile): Remove.
17124 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
17125 * bin/autoscan.in: Adjust.
17127 2003-08-20 Akim Demaille <akim@epita.fr>
17129 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
17130 Reported by Alexandre Duret-Lutz.
17132 2003-08-20 Akim Demaille <akim@epita.fr>
17134 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
17135 * bin/autom4te: Adjust.
17136 In particular, be Autoconf tools are really silent when properly
17137 working, bind the verbosity of the 'note' channel to $verbose.
17138 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
17139 (&xsystem, &contents): Remove, since they are exported by...
17140 * lib/Autom4te/FileUtils.pm: this.
17142 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
17143 * lib/Autom4te/FileUtils.pm: here.
17145 2003-08-20 Akim Demaille <akim@epita.fr>
17147 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
17148 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

17201 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
17202 shorter column three. Add DESCRIPTION to log file content.
17204 2003-08-13 Derek Price <derek@ximbiot.com>
17206 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
17209 2003-08-12 Derek Price <derek@ximbiot.com>
17211 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
17212 (AT_CHECK_NOESCAPE): Move core functionality to...
17213 (_AT_CHECK): ...this new macro.
17215 2003-08-07 Derek Price <derek@ximbiot.com>
17217 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...

17222 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
17223 in Bash 2.01. Problem reported by Brian Gough in

17228 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
17229 -lcrt1.o, for OS X. (trivial change)
17231 2003-07-07 Paul Eggert <eggert@twinsun.com>
17233 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
17234 inside '#ifndef __cplusplus'. Problem reported by
17237 2003-07-06 Bill Clarke <llib@computer.org>
17239 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
17240 'long', not 'int', for benefit of Sun's recent C++ compilers
17241 (trivial change). See:
17242 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

17248 * lib/Makefile.am (autom4te.cfg): Make it read only.
17249 Depend on Makefile since it contains substitutions.
17250 From Paolo Bonzini.
17251 * lib/autom4te.in (args): Add local.at? for Autotest args.
17252 This change was made on autom4te.cfg which is generated.
17253 Reported by Raja R. Harinath.
17255 2003-06-25 Akim Demaille <akim@epita.fr>
17257 * doc/autoconf.texi (Header Portability): sys/mount.h.
17258 From Gareth McCaughan.
17260 2003-06-23 Akim Demaille <akim@epita.fr>
17262 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
17263 not all of them. This fixes 1. the fact that when testing
17264 Autoconf there are many many config.log, 2. the incorrect use of
17265 top_srcdir to find config.log.
17266 Don't mix the detailed output of failed test with the summary of
17267 failures. Rather, append detailed log afterwards.
17269 2003-06-23 Akim Demaille <akim@epita.fr>
17271 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
17272 always run: output config.log on $at_group_log.
17274 2003-06-23 Akim Demaille <akim@epita.fr>
17276 * tests/torture.at (#define header templates): Don't use quotes in
17277 C++ comments as it puzzles Emacs' sh font-lock-mode.

17281 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.

17292 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
17293 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
17294 ensuring we add -std1 for full-ANSI.
17296 * doc/autoconf.texi (hdrindex): New macro.
17297 Add index entries for portability of various standard header files.
17299 2003-06-20 Akim Demaille <akim@epita.fr>

17326 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
17327 (TEST_SCRIPT): New diversion.
17328 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
17329 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
17330 (AT_INIT): Support for expected failures.
17332 2003-06-02 Akim Demaille <akim@epita.fr>
17334 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

17337 Autoconf nor Automake.
17338 (&contents): New, from Automake.
17341 2003-05-28 Paul Eggert <eggert@twinsun.com>
17343 * NEWS, doc/autoconf.texi (Particular Functions),
17344 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
17345 is the inverse of localtime.
17347 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
17349 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
17350 (handle_exec_errors): New function. Work around $! being
17351 altered by WEXITSTATUS.
17352 (xqx, xsystem): Use handle_exec_errors.
17354 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
17356 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
17357 Do not call `_exit()', simply modify `$?'.
17358 (xsystem): Reset $! before running system, and check it afterward.
17359 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
17360 63 for version mismatches.
17362 2003-05-23 Akim Demaille <akim@epita.fr>
17364 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
17365 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
17366 the middle of a line).
17367 * lib/m4sugar/m4sugar.m4: Likewise.
17368 Remove useless spaces in comments.
17370 2003-05-23 Akim Demaille <akim@epita.fr>
17372 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
17373 exit 63, so that we (or Automake's "missing") can tell the
17374 difference with a plain failure.
17375 * doc/autoconf.texi (Notices): Adjust.

17384 Paul Eggert <eggert@twinsun.com>
17386 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
17387 Remove `#include <stdlib.h>' from the list; we should never
17388 make confdefs.h include <stdlib.h> or <cstdlib>, because the
17389 resulting namespace pollution would cause other tests to fail.
17390 Configure scripts run with some older versions of g++ and HP's
17391 aCC would fail due to such an #include. Problems reported by
17392 Matthew Mueller in <http://bugs.debian.org/120704> and by
17394 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
17395 In the test, use the test declaration before including <stdlib.h>,
17396 as that's closer to how it'll be used.
17398 2003-05-23 Akim Demaille <akim@epita.fr>
17400 * doc/autoconf.texi (Header Portability): ucred.h.
17403 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
17405 Overhaul Autotest's logging: generate separate log files
17406 in testsuite.dir/NNN/testsuite.log, and append them to
17407 testsuite.log instead of re-running the test verbosely.
17409 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
17410 file descriptor, write 0 to at_status_file instead of setting
17411 at_status=0, initialize some new variables (at_status_file,
17412 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
17413 to rerun the tests, instead append the at_group_log to the
17414 at_suite_log when a test fails.
17415 (AT_SETUP): pipe the test case's output into at_tee_pipe,
17416 with the AS_MESSAGE_LOG_FD redirected to stdout.
17417 (AT_CLEANUP): save the output status in $at_status_file
17418 and restore it, redirect the AS_MESSAGE_LOG_FD back to
17419 its original place.
17420 (AT_CHECK): since tests are run with a redirected stdout,
17421 and used to be re-run in verbose mode, turn some $at_verbose
17422 into echo, and don't redirect the output of testing stdout
17425 * lib/autotest/autoconf.texi (testsuite Scripts): Update
17426 the name of the debugging directory and information about
17429 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

17461 Reported by Jim Meyering.
17463 2003-05-22 Akim Demaille <akim@epita.fr>
17465 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
17466 Add AC_HELP_STRING to the obsolete macros section.
17468 Use '@.' for sentences that ended in a capital letter.

17501 memcmp be declared before being tested.
17502 Reported by Sander Niemeijer.
17503 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

17505 AC_INCLUDES_DEFAULT.
17507 2003-05-17 Akim Demaille <akim@epita.fr>
17509 * lib/autoconf/specific.m4: Include signal.h and unistd.h.

17546 2003-05-06 Akim Demaille <akim@epita.fr>
17548 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
17549 longer updates aclocal.m4 if useless, (ii) if a file m4_included
17550 by aclocal.m4 is changed it might require the importing of another
17551 m4 extension file, i.e., aclocal must be run.
17553 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
17554 (&parse_args): Use --force with aclocal if required and supported.

17566 (&freeze): Lock the $icache_file.
17568 2003-04-29 Derek Price <derek@ximbiot.com>
17570 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
17571 seperator with m4_append_uniq(). It doesn't work.
17572 (AT_CLEANUP): Add `;' to end of at_help_all.
17573 (AT_INIT): Allow --keywords to be specified more than once. When
17574 grepping $at_help_all for keywords, use the field and keyword
17575 seperators to ensure a complete keyword match. Alter at_prev handling
17576 to support the new --keywords behavior.

17580 * doc/autoconf.texi: Make the dir entries in the autoconf manual
17581 align better with others. I also made some of the individual
17582 entries on one line, for brevity and to make it easier for me to
17583 sort my dir-example file in the Texinfo distribution :).

17650 header causes problems.
17652 2003-03-28 Akim Demaille <akim@epita.fr>
17654 * tests/torture.at (Configuring subdirectories): Require aclocal
17655 1.4, otherwise the test fails, as it does support configure.ac.
17656 This fixes the "test 40 failed" bug reports.
17658 2003-03-28 Akim Demaille <akim@epita.fr>
17660 * doc/autoconf.texi (C Compiler): `#line' portability.

17678 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
17679 obsolete AC_HELP_STRING.
17680 (AC_HELP_STRING): AU_DEFUN to...
17681 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
17682 * tests/m4sh.at (AS_HELP_STRING): New test.

17686 2003-03-26 Derek Price <derek@ximbiot.com>
17688 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
17689 sense. Verbosify the diversion definitions comment.

17729 (Automake): Automake 1.5+ no longer requires special tools to be
17730 present on the developer's host.

17734 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
17735 to a shell that can handle redirection or quoting correctly.

17741 * bin/autoupdate.in (BEGIN): Likewise.
17742 * bin/ifnames.in (BEGIN): Likewise.
17744 * bin/ifnames.in: Add final newline to help and version messages.
17746 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
17747 to cope with DOS-style absolute paths, when constructing
17750 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
17751 When constructing paths with IFS=:, quote the path. If we're
17752 constructing a DOS-style absolute path, we don't want to split it
17755 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
17758 2003-02-25 Pavel Roskin <proski@gnu.org>

17766 2002-09-01 patch by replacing "test -n" with "test -z".
17767 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
17768 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
17770 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
17771 to fix a mismatch between example and discussion.

17775 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
17776 format starting with "-".
17778 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
17780 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
17781 is not portable inside Makefile.
17783 2003-02-20 Akim Demaille <akim@epita.fr>
17785 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
17786 compiler says yeah, but preproc says nope, compiler is right.
17787 Conversely, prompt the reader to send a bug report to the
17788 maintainers of the package, not of Autoconf.

17792 * bin/autoreconf.in (autoreconf_current_directory): Properly
17793 handle an empty aclocal.m4.

17798 $ac_prefix_program.
17801 2002-12-23 Paul Eggert <eggert@twinsun.com>
17803 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
17804 innocuous variant befor including <limits.h> or <assert.h>. This
17805 works around a bug reported by Albert Chin: HP-UX 11i
17806 (and earlier versions) have a <limits.h> that declares
17807 gettimeofday and many other functions.
17809 2002-12-03 Paul Eggert <eggert@twinsun.com>
17813 * NEWS, configure.ac: Update version.
17815 * doc/fdl.texi: Upgrade to FDL version 1.2.
17817 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
17818 nontrivially in main's body, so that f's external declaration is
17819 not optimized away in AIX. This should fix the bug reported by
17821 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
17823 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
17824 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
17825 defined, to support freestanding compilers. This should fix the
17826 bug reported by Momchil Velkov in
17827 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
17829 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
17830 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
17831 obsolete AC_CHECK_TYPE. The missing empty arg was reported

17833 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
17835 * Makefile.maint (www-gnu): New macro.
17836 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
17837 the location has moved.
17839 2002-12-02 Martin Frydl <martin@systinet.com>
17841 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
17842 \(.*\) match is too long and there is something more to be checked.
17843 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
17845 2002-11-15 Akim Demaille <akim@epita.fr>

17861 Update from masters.
17863 2002-11-14 Akim Demaille <akim@epita.fr>
17865 * Makefile.maint: Sync with Bison, i.e.:
17866 (po-check): Scan .l and .y files instead of the
17867 .c and the .h files that they generate. This fixes the bug
17868 reported by Tim Van Holder in:
17869 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
17870 Look for N_ as well as for _. Try to avoid matching #define for
17874 2002-11-14 Akim Demaille <akim@epita.fr>
17876 * doc/autoconf.texi (C Compiler): Compiling several files at once.
17877 From Paul Eggert and Albert Chin-A-Young.
17879 2002-11-14 Akim Demaille <akim@epita.fr>
17881 * doc/autoconf.texi (C Compiler): Solitary backslashes.
17882 From Paul Eggert and Albert Chin-A-Young.
17884 2002-11-14 Kevin Ryde <user42@zip.com.au>
17886 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
17887 than assigning in main, to avoid HP cc +O3 optimizing it away.
17889 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
17891 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
17892 option. Process --recheck after parsing all options. Pass -q
17893 option to configure on --recheck.
17894 (AC_OUTPUT): Pass -q from configure to config.status.
17895 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
17896 arguments to record.
17897 * doc/autoconf.texi (config.status Invocation): Document
17898 config.status -q option.
17900 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
17902 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
17903 Makefile.in if Makefile.am exists.
17904 (output): Strip `.am' from Makefiles. Don't
17905 output AC_CONFIG_FILES if no Makefiles were found.
17907 2002-11-07 Akim Demaille <akim@epita.fr>
17909 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
17910 (local_updates): New.
17911 * Makefile.maint: Update, from CVS Bison.
17912 (local_updates): New.
17914 2002-11-06 Akim Demaille <akim@epita.fr>
17916 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
17917 declaration in extern "C" too.

17925 Reported by Ezra Peisach.
17927 2002-11-05 Akim Demaille <akim@epita.fr>
17929 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
17931 We _have_ to stop using the old compatibility scheme that tried to
17932 avoid useless backslashes because Libtool 1.4.3 contains a
17933 AC_DEFINE([error_t], [int],
17934 [Define to a type to use for \`error_t' if it is not
17935 otherwise available.])
17936 We _have_ to quote the single quote and backslashes with \. The
17937 old compatibility scheme saw that ` was backslashed, and therefore
17938 did not quote the single quote. Hence before this patch, Autoconf
17939 was not compatible with Libtool.
17941 2002-11-04 Paul Eggert <eggert@twinsun.com>
17943 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

17960 (&autoreconf): here.
17961 ($help, $make, &parse_args, &autoreconf_current_directory):
17963 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17965 2002-10-31 Bruno Haible <bruno@clisp.org>

17979 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
17981 2002-10-31 Akim Demaille <akim@epita.fr>
17983 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
17984 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
17985 Make variable, not a shell variable.
17986 Suggested by Bruno Haible.
17988 2002-10-31 Akim Demaille <akim@epita.fr>
17990 * bin/autom4te.in (load_configuration): Reject #args out of any
17993 2002-10-31 Akim Demaille <akim@epita.fr>
17995 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
17996 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
17997 (_AC_RUN_IFELSE): Use it.
17998 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

18006 * doc/autoconf.texi (autom4te Invocation): Adjust.
18007 Suggested by Tim van Holder.
18009 2002-10-29 Paul Eggert <eggert@twinsun.com>
18011 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
18012 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
18013 Problem reported by Bruno Haible.
18015 2002-10-29 Akim Demaille <akim@epita.fr>
18017 * doc/autoconf.texi (Header Templates): Put also in words what the
18018 pictures says to assist free style readers.

18330 Reported by Alexandre Duret-Lutz.
18332 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

18337 (&up_to_date): If a file that was included according to the cache

18352 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
18353 if some file was changed instead of `print'.
18354 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

18388 file name to enable parallel executions.
18389 From Sam Varshavchik.
18391 2002-10-08 Akim Demaille <akim@epita.fr>
18393 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
18394 aclocal invocation, as Gettext macros might not be visible to
18396 Instead of blindly running autopoint, scan configure.ac (not the
18397 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
18398 Reported by Paul D. Smith.
18400 2002-10-08 Paul Eggert <eggert@twinsun.com>
18402 Work around problems found when POSIXLY_CORRECT=1 is set.
18403 None of this seems to have anything to do with POSIX, really,
18404 but it's how Perl getopt works.
18405 * bin/autom4te.in (parse_args): Configure GetOpt with
18407 * doc/autoconf.texi (Invoking autom4te):
18408 --warning -> --warnings.

18430 * tests/torture.at (Configuring subdirectories): Be robust to
18431 users who use config.site to require for a cache: in this case,
18432 the two last configure runs, using two different sets of
18433 arguments, trigger a legitimate error.
18435 2002-09-28 Akim Demaille <akim@epita.fr>

18470 tests/autom4te itself.

18472 (autoscan.list): New target --this file is no longer a source.

18477 * bin/autoscan.in (@kinds): Make them singular.
18479 (&init_tables): When --debug, report the list of rules to ease
18480 tracking changes in autoscan.list.
18481 * lib/autoscan/autoscan.list (function): Strip comments, sort.
18483 2002-09-28 Akim Demaille <akim@epita.fr>

18497 * bin/autoscan.in (&init_tables): Adjust.
18499 2002-09-28 Akim Demaille <akim@epita.fr>
18501 From now on, autoscan files must always map a macro name to a
18502 word: there is no `default' macro for autoscan.
18504 * bin/autoscan.in (&init_tables): Reject entries with no macro at
18506 * lib/autoscan/functions, lib/autoscan/headers: Make the macro

18529 the tmpdir must be created.
18530 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
18531 dir be in the build tree, instead of $TMPDIR.
18533 2002-09-27 Akim Demaille <akim@epita.fr>
18535 * bin/autoscan.in: Improve the comments.

18557 2002-09-25 Paul Eggert <eggert@twinsun.com>
18559 * BUGS (Interoperability bugs): New section. Mention libtool
18560 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
18562 2002-09-24 Paul Eggert <eggert@twinsun.com>
18564 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
18565 make handles suffix-rules differently from GNU make.
18567 * bin/Makefile.am (SUFFIXES, .in): Remove.
18568 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
18569 Move the body of the old .in rule here.
18571 2002-09-16 Akim Demaille <akim@epita.fr>
18573 i960 compilers create `b.out' files by default.
18574 Reported by Ralf Corsepius.
18576 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
18577 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
18579 2002-09-13 Paul Eggert <eggert@twinsun.com>
18581 * doc/autoconf.texi (Particular Headers): Remove obsolete
18582 reference to `struct timezone' in the description of

18593 2002-09-13 Akim Demaille <akim@epita.fr>
18595 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
18596 reading config.log when the compiler is rejected.
18597 Suggested by Guido Draheim.
18599 2002-09-13 Akim Demaille <akim@epita.fr>
18601 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
18602 (chdir_init) might hang when stat'ing mounted directories.
18603 Reported by Vance Shipley.
18605 2002-09-12 Akim Demaille <akim@epita.fr>
18607 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
18610 2002-09-12 Akim Demaille <akim@epita.fr>
18612 * doc/autoconf.texi (Defining Symbols): Present two different
18613 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
18614 difference between 1 argument calls, and 2-3 argument calls.
18616 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
18618 * doc/autoconf.texi: Review grammar and punctuation.
18620 2002-09-11 Paul Eggert <eggert@twinsun.com>
18622 * doc/autoconf.texi: Fix minor formatting, spelling, and
18624 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
18625 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
18628 2002-09-11 Akim Demaille <akim@epita.fr>
18630 * doc/autoconf.texi (Questions): Rename as...
18632 (Defining Directories): New.
18634 2002-09-09 Akim Demaille <akim@epita.fr>
18636 * doc/autoconf.texi (Making testsuite Scripts): Update.
18637 Suggested by Nishio Futoshi.
18639 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
18641 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
18642 plain `@' is wanted.
18644 2002-09-09 Akim Demaille <akim@epita.fr>
18646 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
18647 `duplicates', since the algorithm was too naive and could keep
18648 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
18649 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
18650 Reported by Ralf Corsepius.
18651 * tests/torture.at (Configuring subdirectories): Exercise these
18654 2002-09-09 Akim Demaille <akim@epita.fr>
18656 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
18657 looking for a replacement file.
18658 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
18659 directory is relative.
18660 * doc/autoconf.texi (Generic Functions): Clarify the replacement
18661 directory definition.
18662 Reported by Andreas Schwab and Jim Meyering.
18664 2002-09-06 Akim Demaille <akim@epita.fr>
18666 * doc/autoconf.texi (Setting Output Variables): Clarify what
18667 precious variables are.
18668 Suggested by Pontus Skoeld.
18670 2002-09-05 Akim Demaille <akim@epita.fr>
18672 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
18673 (ifnames, autoscan, autom4te): Since we don't only depend on
18674 configure.ac variables (such as VERSION etc.), but also on prefix
18675 and so forth, depend on Makefile, not configure.ac.
18676 Reported by Alexandre Duret-Lutz.
18677 * doc/autoconf.texi (Installation Directory Variables): Adjust.
18679 2002-09-05 Kevin Ryde <user42@zip.com.au>
18681 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
18682 doesn't seem to be confined to ia64, just say "some versions".
18684 2002-09-04 Akim Demaille <akim@epita.fr>
18686 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
18688 * Makefile.am (maintainer-clean-local): Remove.

18691 2002-09-03 Paul Eggert <eggert@twinsun.com>
18693 * doc/autoconf.texi (Configuration Commands): Remove obsolete
18694 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
18697 2002-09-03 Akim Demaille <akim@epita.fr>
18699 * configure.ac: Bump to 2.53d.
18700 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
18701 as of today, on Automake's team suggestion.
18703 2002-09-03 Akim Demaille <akim@epita.fr>
18707 2002-09-02 Akim Demaille <akim@epita.fr>
18709 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
18711 * configure.ac: Disable SITE_MACRO_DIR.
18713 2002-09-02 Jim Meyering <meyering@lucent.com>
18715 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
18716 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
18717 Also, tweak grammar: s/make sure to/be sure to/.
18719 2002-09-02 Paul Eggert <eggert@twinsun.com>
18721 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
18722 directory names are generally preferable to physical names.
18724 2002-09-02 Akim Demaille <akim@epita.fr>
18726 * lib/Autom4te/General.pm (&update_file): s/die/error/.
18727 Reported by Raja R. Harinath.
18728 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
18729 * bin/autoupdate.in: Use error instead of die.
18731 2002-09-01 Paul Eggert <eggert@twinsun.com>
18733 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
18734 ordinary shell concatenation rather than echo+tr+sed command that
18735 runs afoul of a long-line-related sed bug in Solaris 8.
18737 * bin/autoheader.in (parse_args): --warning -> --warnings.
18739 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
18740 stdout, as traditional "ls" does.
18741 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
18742 _AC_COMPILER_EXEEXT_O): Likewise.
18743 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
18745 * bin/autoconf.as: Add --prepend-include option. This patch was
18746 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
18747 but bin/autoconf.in is generated automatically from bin/autoconf.as.
18749 * bin/autoconf.in, configure: Regenerate.
18751 * doc/autoconf.texi (Special Shell Variables): Mention
18752 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
18754 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
18755 MAILPATH and set PS1, PS2, PS4 to default values, to work
18756 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
18757 For LC_ALL etc, first try to set to "C" as POSIX requires and as
18758 the Autoconf documentation specifies; fall back to "unset" only if
18759 this fails. Use a shell for-loop for this rather than an m4 loop,
18760 to shorten the output script.
18762 2002-08-30 Paul Eggert <eggert@twinsun.com>
18764 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
18765 1003.1-2001's requirements for CDPATH. Give a simpler workaround
18766 for the CDPATH problem. Document PWD.
18767 (Limitations of Builtins): Document the problem that "cd $foo" and
18768 "ls $foo" may refer to different directories in shells conforming
18769 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
18770 example, since the old example is now out of date.
18772 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
18773 FOO" and "ls FOO" talk about different directories; this catches
18774 problems when POSIX 1003.1-2001 "cd" fails due to symlink
18777 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
18778 of rolling our own unset.
18779 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
18780 in practice we needn't worry about CDPATH if unset doesn't work.
18782 * Makefile.in, aclocal.m4, bin/Makefile.in,
18783 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
18784 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
18785 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
18786 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
18787 tests/Makefile.in: Regenerate with Automake 1.6.3.
18789 * config/config.guess, config/config.sub, config/mkinstalldirs:
18792 * configure: Regenerate with self.
18794 2002-08-30 Kevin Ryde <user42@zip.com.au>

18804 2002-08-29 Akim Demaille <akim@epita.fr>
18806 * lib/Autom4te/General.pm (&xqx): New.
18807 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
18808 hand, which is not portable.
18810 * bin/autom4te.in: Use them.
18811 Use &error instead of die.
18812 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
18815 2002-08-17 Paul Eggert <eggert@twinsun.com>
18817 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
18818 default list of compilers to try, since it was long ago superseded
18819 by the ksh fc builtin. Suggested by Steven G. Johnson.
18821 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
18823 * doc/autoconf.texi (Invoking autom4te): End the option table,
18824 fixing a bug introduced by the previous patch.
18825 (Limitations of Make): Add a 'target lookup' subentry in the
18826 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
18828 2002-07-29 Mark D. Roth <roth@feep.net>
18830 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
18831 options and use $AUTOM4TE_PATH.
18832 * doc/autoconf.texi: Remove documentation of autom4te
18833 --include-envvar and --site-macro-subdir options and document
18834 use of $AUTOM4TE_PATH.
18835 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
18836 arguments from each language section.
18838 2002-07-29 Paul Eggert <eggert@twinsun.com>
18840 * doc/install.texi: Include copyright symbol in copyright notice.
18842 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
18844 (AM_MAKEINFOFLAGS): New macro.
18845 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
18846 * Makefile.am (INSTALL): Use the new macros.
18847 Use -o rather than --output, since "missing" does not grok --output.
18849 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18851 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
18852 comments do not always work. Never trust the exit status of
18855 2002-07-24 Kevin Ryde <user42@zip.com.au>
18857 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
18858 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
18860 2002-07-23 Paul Eggert <eggert@twinsun.com>
18862 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
18863 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
18864 apparently treats PATH="nonexistent" as if it contained ".".
18865 Bug reported by Stefan `Sec' Zehl.
18867 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18869 * doc/autoconf.texi (Limitations of Make): Mention the special
18870 handling of the obj/ directory by BSD make.

18917 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
18918 latter was not run.

19135 This improves on an earlier suggestion by H. Peter Anvin.
19137 2002-05-16 Paul Eggert <eggert@twinsun.com>
19139 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
19140 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
19141 Both macros now accept an optional source-dir arg.
19142 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
19144 * NEWS: Document this.
19145 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
19147 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
19148 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
19149 not for GNU extensions; this undoes part of the 2000-11-03 change,
19150 reverting to 2.13-compatible behavior.

19158 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
19159 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
19160 and it causes a 'test' syntax error if it fails.
19161 Bug reported by Stephen Gildea.
19163 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
19164 If prototypes are supported, use them to check this at compile-time,
19165 instead of trying to check it at run-time. If we must do a run-time
19166 check, assume that setvbuf is standard when cross-compiling, as
19167 nonstandard setvbuf occurs only on ancient and unlikely hosts.
19168 Bug reported by Paul D. Smith.
19170 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
19171 argument specifying location of getloadavg.c. This removes a
19172 FIXME. This idea was taken from Jim Meyering's implementation in
19174 * doc/autoconf.texi (Particular Functions): Document this.
19175 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
19176 that's what the code does; this fixes a bug reported by

19181 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
19182 autopoint instead of gettextize.
19183 ($uses_alocal): Rename as...
19184 ($uses_aclocal): this.
19185 * doc/autoconf.texi (autoreconf Invocation): Adjust.
19186 Suggested by Bruno Haible.

19192 2002-04-29 Paul Eggert <eggert@twinsun.com>
19194 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
19195 files to be 1 second older; just set them to be the same time.
19196 Also, sleep 1 second after the first aclocal, to work around
19197 problems with sub-second time stamps on the input files.
19199 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
19201 * doc/autoconf.texi: Mention "set -e -x" lossage

19208 From Christian Cornelssen.
19210 2002-04-29 Akim Demaille <akim@epita.fr>
19212 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
19213 of lack of $LINENO support, then the test will compare the $LINENO
19214 in testsuite vs. the lineno in the test file. This is wrong, of
19216 Be sure to protect it.
19217 Reported by Patrick Welche.
19219 2002-04-25 Akim Demaille <akim@epita.fr>
19221 * doc/autoconf.texi (Obsolete Macros): Typo.
19222 Reported by Vladimir Volovich.
19224 2002-04-25 Akim Demaille <akim@epita.fr>
19226 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
19227 than some of the input files, hence, on the second run of aclocal,
19228 if some of its input are younger, make them older.
19229 Suggested by Paul Eggert.
19231 2002-04-25 Akim Demaille <akim@epita.fr>
19233 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

19242 (_AC_INIT_PREPARE): Use them to log them.
19243 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
19244 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
19245 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
19246 _AC_SUBST_FILES and _AC_SUBST_VARS.
19247 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
19249 2002-04-24 Akim Demaille <akim@epita.fr>
19251 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
19252 autoheader, so that automake does not complain about a missing

19488 * doc/autoconf.texi (Assignments): Document the problem.
19490 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
19492 * doc/autoconf.texi (Limitations of Make): Mention more issue
19493 about VPATH, overriding of macros in sub-makes, and handling of
19496 2002-03-21 Paul Eggert <eggert@twinsun.com>
19498 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
19499 problem with here-document buffer boundaries.
19501 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
19502 when reinvoking the shell, to work around problems with installers
19503 who put strange things like "cd" commands in their environments.
19505 2002-03-19 Akim Demaille <akim@epita.fr>
19507 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
19510 2002-03-19 Akim Demaille <akim@epita.fr>
19512 * bin/autoscan.in (scan_file): Specify the location in `&used'
19516 2002-03-19 Akim Demaille <akim@epita.fr>

19519 From Nishio Futoshi.
19521 2002-03-19 Akim Demaille <akim@epita.fr>
19523 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
19525 2002-03-18 Paul Eggert <eggert@twinsun.com>
19527 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
19528 (Limitations of Usual Tools): Add mkdir section.
19530 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
19531 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
19532 back on AS_DIRNAME to compute prefixes otherwise; this is
19533 roughly what mkinstalldirs does. That way, we need not have
19534 our own filename disassembler. The old disassembler did not
19535 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
19537 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
19538 Create at_test_all by a series of assignments,
19539 not by a single assignment of a long string. The latter causes ksh
19540 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
19541 presumably because of a buffer overrun.
19543 2002-03-14 Paul Eggert <eggert@twinsun.com>
19545 * lib/autotest/general.m4 (at_times_skip):
19546 Renamed from at_times. Now a boolean.
19547 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
19548 says 'times: not found'.

19552 * bin/autoreconf.in (&study_gettextize): New.
19553 (&autoreconf): Handle newest gettextize.

19577 2002-03-11 Andreas Schwab <schwab@suse.de>

19591 2002-03-08 Akim Demaille <akim@epita.fr>
19593 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
19595 2002-03-08 Akim Demaille <akim@epita.fr>
19597 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
19598 aliases the actual variables, and modifications of the former
19601 2002-03-08 Akim Demaille <akim@epita.fr>
19603 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
19604 because of C-c: have m4 output in tmp files, then mv them.

19627 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
19628 * lib/autoconf/general.m4 (AC_INIT): More informative error
19629 message for LIBOBJ.
19631 2002-03-04 Akim Demaille <akim@epita.fr>

19636 2002-03-04 Akim Demaille <akim@epita.fr>
19638 * doc/autoconf.texi (Transforming Names): Equality between target
19639 and host is irrelevant.
19640 (Specifying Names, Canonicalizing): Remove all references to the
19641 backward compatibility hooks. Rather, collect them all into...
19642 (Hosts and Cross-Compilation): this new section.
19643 * doc/install.texi (System Type): Ditto.
19644 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
19645 that `--host' implies cross-compilation.
19647 2002-03-04 Akim Demaille <akim@epita.fr>
19649 * doc/autoconf.texi (Evaluation Macros): New.
19650 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
19652 (_m4_foreach): Define the variant with immediate evaluation so
19653 that it contains exactly the items, not an expression which
19654 evaluation is the current item.
19655 (m4_re_string, m4_re_word): Don't over quote them.
19657 2002-03-04 Akim Demaille <akim@epita.fr>
19659 Instead of having stacking `shift's evaluated at the end, let
19660 `foreach' loops immediately evaluate them.
19662 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
19663 $*. This is the n-th time I change my mind, but hopefully this is
19666 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
19668 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
19669 it was only a hack for m4_text_wrap.
19670 (m4_car2): Remove, replaced by...
19672 (_m4_foreach): Adjust.
19673 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
19674 m4_bpatsubst for clarification.

19726 AC_PREFIX_PROGRAM fails with dashed program names
19728 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

19765 2002-02-05 Akim Demaille <akim@epita.fr>
19767 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

19790 optional are the sum of the previous files on the command line'.
19791 Also, pass `--reload-state=' on them, so...
19792 (handle_m4): don't.

19794 (M4sh): Rely on M4sugar.

19832 2002-01-28 Akim Demaille <akim@epita.fr>
19834 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
19835 AUTOTEST_PATH *after* it was set.
19836 Don't put `.' in the PATH: the user should be precise and `./' if
19837 needed. In addition, given that the test suite does some `cd', if
19838 `.' is in the path, the `tested programs' sections will report
19839 programs found in the test suite's directory, while during the
19840 tests (performed in their own directory), these programs are no
19841 longer visible. In other words, the results is confusing and
19843 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

19890 Autoconf::General::getopt with non valid options.

19894 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

19912 * tests/Makefile.am (package.m4): New.
19913 EXTRA_DIST it since its a source.
19915 2002-01-06 Akim Demaille <akim@epita.fr>

19918 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
19919 and PACKAGE_BUGREPORT from here...
19920 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
19922 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
19923 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
19924 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
19925 * tests/tools.at (autoheader): Adjust.

19947 2001-12-14 Akim Demaille <akim@epita.fr>
19949 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
19950 trailing files, don't apply `-rf' to files which might not be
19951 created by configure (core, core.*, and *.core), but just `rm -f'.
19952 Suggested by Jonathan Kamens.
19954 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

20002 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
20003 Remove, replaced by...
20004 * tests/wrappl.in: Be common for all the Perl executables.
20005 In particular autoscan and autoheader want -I.
20006 * configure.ac: Adjust.
20007 * lib/autoscan/headers: errno.h is portable.
20009 2001-11-26 Akim Demaille <akim@epita.fr>
20011 * bin/autoscan.in (used): New.
20014 2001-11-26 Akim Demaille <akim@epita.fr>
20016 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
20018 (&scan_sh_file): Remove a duplicate pattern.
20019 (&check_configure_ac): Use long options.
20020 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
20022 2001-11-26 Akim Demaille <akim@epita.fr>
20024 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
20025 Before, having a line containing the opening of a multi line
20026 comment made the whole line be ignored.
20028 2001-11-26 Akim Demaille <akim@epita.fr>
20030 * doc/autoconf.texi (Using an Autotest Test Suite): New.
20031 (testsuite Scripts): Be one of its subsection.
20032 (Autotest Logs): New.
20034 2001-11-26 Akim Demaille <akim@epita.fr>
20036 Test groups are now run two directories deeper.
20038 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
20039 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
20041 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
20042 top_srcdir, builddir and top_builddir.
20043 Use `at_*dir' relatively to the directory containing the
20044 suite, use `*dir' when relatively to the current group dir.
20046 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
20048 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
20049 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
20050 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
20053 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
20055 * doc/autoconf.texi (Using System Type): Add an example of `case
20056 $host' usage so people quit using `case $target' everywhere.
20058 2001-11-22 Akim Demaille <akim@epita.fr>
20060 * doc/autoconf.texi (Installation Directory Variables): Englishoes
20061 spotted by Jim Meyering.
20063 2001-11-16 Paul Eggert <eggert@twinsun.com>
20065 This patch implements a `long double' suggestion by Oliver Kiddle.
20067 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
20068 static, to catch errors if the value isn't known at compile-time
20069 and the compiler supports dynamic arrays. Change its name from
20070 `_array_' to `test_array' to avoid potential name clashes.
20071 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
20072 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
20073 better than double. Catch a bug in GCC 2.95.2 x86.
20074 * doc/autoconf.texi (C Compiler): Document the above.
20077 2001-11-13 Akim Demaille <akim@epita.fr>
20079 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
20081 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
20083 2001-11-13 Akim Demaille <akim@epita.fr>
20085 * lib/autotest/general.m4 (AT_INIT): After having run the test
20086 group, go back to the initial directory, not to at_suite_dir.
20088 2001-11-13 Akim Demaille <akim@epita.fr>
20090 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
20091 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
20092 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
20094 (AT_CHECK_CONFIGURE): Use absolute paths.
20095 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
20096 The problem is still the old one: there is no means in M4 (that I
20097 know about) to create a defining macro, because there is no means
20098 to create `$1' etc., therefore, the defining macro ``swallows''
20099 all the arguments meant to the defined macro.
20101 2001-11-13 Akim Demaille <akim@epita.fr>
20103 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
20104 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
20106 * tests/aclocal.m4: Remove, as it is no longer used.
20108 2001-11-13 Akim Demaille <akim@epita.fr>
20110 * lib/autotest/general.m4: Change `tests?' into `groups?' in
20111 variable names when referring to a single test group, or to
20112 `suite' when referring to the whole test suite.
20113 `at_last_test' is removed: m4 compute at_format itself.
20114 (at_stdout, at_stder1, at_stderr): New variables.
20115 (AT_CHECK): Use them.
20117 2001-11-13 Akim Demaille <akim@epita.fr>
20119 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
20121 Create `testsuite.dir/003/run' instead of `testsuite.003'.
20122 Do it as soon as a test fails, don't wait till the end of the test
20124 Don't remove $as_me.[0-9]*, since these files no longer exist.
20126 2001-11-13 Akim Demaille <akim@epita.fr>
20128 * tests/tools.at: Use absolute paths, since we are no longer run
20131 2001-11-13 Akim Demaille <akim@epita.fr>
20133 Now that tests are running in their own private dir, there is no
20134 need to list the files to remove at the end of tests groups.
20136 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
20137 (AT_data_files, at_data_files): Remove.
20138 (AT_CLEANUP, AT_DATA): Simplify.
20140 Remove the group dir if !debug && !failed.
20141 * tests/atspecific.m4: Adjust.
20143 2001-11-13 Akim Demaille <akim@epita.fr>
20145 Start a new layout for Autotest: `testsuite' creates
20146 `testsuite.dir' in which the at-check-line etc. files are to be
20147 found, and `testsuite.dir/003' where the test group 3 is run.
20149 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
20150 at_check_line_file, at_format, at_test_normalized, at_group_dir
20152 Create the directories.
20153 Use absolute paths for at- files.
20154 (AT_CHECK): Adjust.
20156 2001-11-11 Michael Matz <matz@kde.org>
20158 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
20160 (m4_car): Properly quote arguments.
20162 2001-11-13 Akim Demaille <akim@epita.fr>
20164 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
20165 with stricter rules on LIBOBJS.
20167 2001-11-12 Paul Eggert <eggert@twinsun.com>
20169 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
20170 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
20173 2001-11-12 Akim Demaille <akim@epita.fr>
20175 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
20177 2001-11-12 Akim Demaille <akim@epita.fr>
20179 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
20180 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
20181 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
20182 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
20183 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
20184 specify to what the macro should be defined (typically to 1).
20186 2001-11-12 Akim Demaille <akim@epita.fr>
20188 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
20191 2001-11-12 Akim Demaille <akim@epita.fr>
20193 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
20194 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
20195 definition used by Automake where LEX is +/- "${missing} lex" and
20196 `missing' itself contains variables.
20198 2001-11-12 Akim Demaille <akim@epita.fr>
20200 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
20201 Now that M4sh pushes BODY, the comments were output at the end of
20204 2001-11-08 Akim Demaille <akim@epita.fr>
20206 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
20207 that we can trace macros from aclocal.m4.
20208 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
20209 obsoleted, and redirect to the former anyway.
20210 Reported by Ralf Corsepius.
20212 2001-11-08 Akim Demaille <akim@epita.fr>
20214 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
20215 processed only if present.
20216 * tests/torture.at (Configuring subdirectories): Use autoreconf
20217 instead of successive calls to autoconf.
20218 Add a nonexistent subdirectory to exercise the patch above.
20219 Reported by Ralf Corsepius.
20221 2001-11-08 Kevin Ryde <user42@zip.com.au>
20223 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
20224 doesn't accept .S files.
20226 2001-11-07 Akim Demaille <akim@epita.fr>
20228 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
20229 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
20230 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
20231 * bin/autom4te.in (warn_forbidden): New.
20232 (handle_output): Use it.
20233 Read m4_pattern_forbid with messages.
20235 2001-11-05 Akim Demaille <akim@epita.fr>
20237 * bin/autom4te.in (--normalize): Remove.
20238 * lib/autom4te.in: Adjust.
20240 2001-11-05 Akim Demaille <akim@epita.fr>
20242 * tests/Makefile.am (testsuite): Rename this target as...
20243 ($(TESTSUITE)): this.
20246 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
20248 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
20249 the --prefix option, also remove it's argument.
20251 2001-11-05 Akim Demaille <akim@epita.fr>
20253 * doc/autoconf.texi (testsuite Invocation): Update.
20254 (Writing testsuite.at): Update.
20256 2001-11-03 Akim Demaille <akim@epita.fr>
20258 * doc/autoconf.texi: s/@code/@command/ where appropriate.
20260 2001-11-03 Akim Demaille <akim@epita.fr>
20262 * lib/Autom4te/General.pm: (&catfile, &canonfile)
20263 (&file_name_is_absolute): New, wrappers around routines from
20265 Use and export them.
20266 (&find_configure_ac): Optionally take a directory where to look at.
20267 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
20269 Default @ARGV to `.', not find_configure_ac.
20270 (&autoreconf): Argument is a directory.
20271 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
20272 * doc/autoconf.texi (autoreconf Invocation): Update.
20274 2001-11-03 Akim Demaille <akim@epita.fr>
20276 * lib/Autom4te/General.pm (@export_vars, @export_subs)
20277 (@export_forward_subs): New.
20278 Add basename, dirname, and fileparse.
20280 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
20281 Don't look for aclocal flags if we already know aclocal is not
20283 Move aclocal.m4t only if it exists.
20284 Reported by Ezra Peisach.
20286 2001-11-03 Akim Demaille <akim@epita.fr>
20288 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
20289 passed on command line, defaulting to ./configure.ac if present.
20290 (&maybe_autoreconf, File::Find): Remove, unused.
20291 (&autoreconf): If autoconf is not used, don't try to trace.
20293 2001-11-02 Akim Demaille <akim@epita.fr>
20295 * configure.ac: Bump to 2.52g.
20297 2001-11-02 Akim Demaille <akim@epita.fr>
20301 2001-11-02 Akim Demaille <akim@epita.fr>
20303 * config/config.guess, config/config.sub, doc/standards.texi:
20304 * config/lispdir.m4: Update from masters.
20305 * configure.ac: Bump to 2.52f.
20307 2001-11-02 Akim Demaille <akim@epita.fr>
20309 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
20310 Don't run aclocal when aclocal.m4 is not from aclocal.
20312 Don't run libtoolize and gettextize if --install is not given.
20314 2001-11-01 Paul Eggert <eggert@twinsun.com>
20316 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
20317 be invoked before _AS_LINENO_PREPARE.
20318 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
20319 than character ranges.
20321 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
20322 invoking AS_BASENAME. Set the locale variables to 'C' if
20323 possible, as POSIX requires this to get the traditional
20325 * doc/autoconf.texi (Special Shell Variables): Describe the above.
20327 2001-10-31 Paul Eggert <eggert@twinsun.com>
20329 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
20330 with {}, as that triggers a bug in Bash 2.05.
20332 (_AS_LINENO_PREPARE): Use Sed rather than
20333 Awk. Fix the sed prepass to work even if there are multiple
20334 instances of $LINENO on the same line. Do not substitute for
20335 other variables like $LINENOT. Do not check file dates; such a
20336 check is unreliable on sufficiently fast machines, and removing
20337 the check makes the code simpler and more reliable. Check for
20338 output and chmod failures.
20340 * doc/autoconf.texi (Special Shell Variables): Document
20343 2001-10-31 Akim Demaille <akim@epita.fr>
20345 * tests/Makefile.am (atconfig): Remove this target, Automake
20348 2001-10-31 Akim Demaille <akim@epita.fr>
20350 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
20351 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
20352 provided, while it is optional.
20353 * configure.ac: Adjust.
20355 2001-10-26 Paul Eggert <eggert@twinsun.com>
20357 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
20358 lib/Autom4te/Struct.pm:
20359 Require Perl 5.005_03 instead of just 5.005, as some tests fail
20362 * doc/autoconf.texi (Special Shell Variables): Document some
20363 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
20365 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
20366 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
20367 eval $LINENO is not portable in practice.
20369 2001-10-24 Akim Demaille <akim@epita.fr>
20371 * lib/Autom4te/General.pm (backname): New.
20373 2001-10-24 Akim Demaille <akim@epita.fr>
20375 * m4/: Remove, merged into...
20378 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
20380 * doc/autoconf.texi (Shellology): Mention the problems with bash
20381 2.05's use of ANSI quoting in its `set' builtin.
20383 2001-10-22 Paul Eggert <eggert@twinsun.com>
20385 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
20386 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
20387 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
20388 POSIX decided to standardize on the int flavor of strerror_r.
20389 Always do char* test, as there's no reason not to.
20390 Assign to a char* var, to catch strerror_r that returns int*.
20392 * doc/autoconf.texi (Particular Functions):
20393 Document the above changes. Also, document the fact that
20394 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
20396 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
20398 2001-10-20 Akim Demaille <akim@epita.fr>
20400 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
20401 the executable was missing from the log.
20403 2001-10-20 Akim Demaille <akim@epita.fr>
20405 * lib/Autom4te/General.pm (&update_file): If destination is
20406 unchanged, remove the source.
20407 (&up_to_date_p): Don't be verbose, be debug.
20408 * bin/autoreconf.in: No longer support --m4dir.
20409 (&autoreconf): Display the full path of the configure.ac we are
20411 Trace it only once.
20412 Be sure to honor --force with gettextize.
20413 Always run aclocal.
20414 * doc/autoconf.texi: Adjust.
20416 2001-10-20 Akim Demaille <akim@epita.fr>
20418 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
20420 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
20421 `intl' is already present, as it refuses unless --force.
20422 (&parse_args): Use -I, --include instead of the old Autoconf
20424 ($localdir, $autoconf_dir): Remove.
20426 (&maybe_autoreconf): New, to preserve $_ for File::Find.
20428 2001-10-19 Jens Petersen <petersen@redhat.com>
20430 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
20431 * doc/autoconf.texi (Particular Programs): Likewise.
20433 2001-10-19 Akim Demaille <akim@epita.fr>
20435 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
20436 file in @configure_input@.
20437 Don't mention `automatically' in addition to `generated'.
20438 * tests/torture.at (#define header templates): Adjust.
20440 2001-10-19 Akim Demaille <akim@epita.fr>
20442 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
20443 comment, explain how to install automatic mode selection.
20446 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
20448 * bin/autoreconf.in (autoreconf): Display the path to the
20449 configure.ac being studied.
20451 2001-10-18 Paul Eggert <eggert@twinsun.com>
20453 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
20454 long, to work around a bug in the HP C compiler version HP92453-01
20457 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
20458 (AS_BASENAME_EXPR): New macro.
20459 (AS_BASENAME_SED): Do not assume GNU sed semantics.
20460 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
20461 and fall back on 'sed' only if the other two fail. This makes
20462 AS_BASENAME act more like AS_DIRNAME.
20463 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
20464 contains white space.
20465 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
20466 Use AS_DIRNAME, since I think it's now DOS-friendly.
20467 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
20468 Allow "dirname //FOO" to return either / or //, as POSIX allows
20471 2001-10-10 Akim Demaille <akim@epita.fr>
20473 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
20474 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
20477 2001-10-10 Akim Demaille <akim@epita.fr>
20479 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
20480 m4_define, since...
20481 (_AS_ECHO_N): AS_REQUIREs it.
20483 2001-10-10 Akim Demaille <akim@epita.fr>
20485 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
20486 (AC_INCLUDES_DEFAULT): Move to...
20487 * lib/autoconf/headers.m4: here.
20488 * lib/autoconf/types.m4: Comment changes.
20489 * doc/autoconf.texi: Specify where the default includes are used
20490 in the macro prototypes.

20957 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
20959 Add test for AS_BASENAME.
20960 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
20961 added test. It now correctly handles /1/2/3/, returning '3' not ''.
20962 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
20963 * tests/base.at: Fixed the expected responses. The old ones were
20965 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
20966 the documentation claims it should (and how it behaved in 2.13).
20968 2001-09-18 Akim Demaille <akim@epita.fr>
20970 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
20971 the AC_CONFIG_COMMANDS invocation.
20972 This also solves the name clash problems.
20973 Don't set the package's ID.
20974 * lib/m4sugar/Makefile.am (version.m4): Revamp.
20975 No longer to be shipped.
20976 (version.in): Remove.
20977 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
20978 * lib/autoconf/status.m4: Adjust.
20979 Use `m4_PACKAGE_STRING'.
20980 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
20981 the only optional argument is the name of the test suite.
20982 Expect `package.m4' to define the package signature.
20983 * lib/autom4te.in (Autotest): Add `package.m4?'.
20984 * tests/Makefile.am (package.m4): New.
20985 * tests/suite.at: ifnames is a victim.
20987 2001-09-18 Akim Demaille <akim@epita.fr>
20989 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
20990 AC_LIBSOURCE, AC_CONFIG_FILES.

20998 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
20999 Allow expression to return any value that can fit into unsigned long
21000 (not int, as before). Check for output errors.
21002 2001-09-17 Bruno Haible <haible@ilog.fr>
21004 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
21005 Always include <stdio.h> and <stdlib.h>. Evaluate
21006 the expression in an extra function before these includes. Call
21007 fprintf "%d" only after ensuring the argument is of type 'int'.
21008 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
21010 2001-09-17 Paul Eggert <eggert@twinsun.com>
21012 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
21013 or CFLAGS=-O5. In that case, the linker has a relaxed view of
21014 fatal errors, and AC_CHECK_LIB causes it to include libraries even
21015 when they don't exist.
21017 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
21018 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
21021 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
21022 version with the version used by fileutils 4.1, except use
21023 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

21028 2001-09-13 Akim Demaille <akim@epita.fr>

21068 * lib/autotest/general.m4 (AT_INIT): Create and remove
21069 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
21070 test suites can cohabit.
21072 2001-09-13 Akim Demaille <akim@epita.fr>
21074 * tests/mktests.sh: Don't output banners for empty test files.

21126 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

21129 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

21142 2001-09-07 Akim Demaille <akim@epita.fr>
21144 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5

21173 to avoid GCC warnings.
21176 2001-09-05 Akim Demaille <akim@epita.fr>
21178 * bin/autom4te.in: --language is -l, not -s.
21180 2001-09-05 Akim Demaille <akim@epita.fr>
21182 Be ready to handle filenames as stupid as `dnl.at', for if even
21183 the maintainer is dumb enough to do that...
21185 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
21186 excellence in M4 quotation: consider `__file__' is active.
21188 And BTW, when invoking m4, pass the --include in the right order:
21191 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

21219 New, extracted from main.
21220 Use IO::File wherever possible.
21221 (input.m4): Be constant, use -I instead of hard coding $tmp.
21222 Therefore be a quoted heredoc.
21223 Don't invoke `_au_disable', since ac was not loaded, but just

21251 2001-08-31 Akim Demaille <akim@epita.fr>
21253 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
21254 (testsuite Scripts): There is no such thing as `atconfig.in'.
21255 And actually one diagram is missing: test suite runtime.
21257 2001-08-31 Akim Demaille <akim@epita.fr>
21259 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
21262 2001-08-31 Akim Demaille <akim@epita.fr>
21264 * bin/autoupdate.in (@include): `installcheck' revealed the path
21265 to m4sugar was lacking!
21267 2001-08-31 Akim Demaille <akim@epita.fr>
21269 * man/Makefile.am (.x.1): We really have to pass
21270 autom4te_perllibdir.
21272 2001-08-31 Akim Demaille <akim@epita.fr>
21274 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
21275 debug scripts, in particular passing explicitly listed tests to

21280 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
21281 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
21282 Use directly autom4te, not autoconf.

21323 * bin/autoupdate.in, bin/autoheader.in: Adjust.
21324 Drop AC_MACRODIR dead for real.
21325 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
21326 `autoheader: `config.hin' is created'.
21327 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
21329 2001-08-31 Akim Demaille <akim@epita.fr>
21331 * bin/autoheader.in: Rewrite in Perl.

21334 2001-08-31 Akim Demaille <akim@epita.fr>
21336 * bin/autoconf.in (--include, -I): New option.
21337 Map --localdir, --autoconf-dir onto it.
21338 Forward autom4te's options instead of interpreting them.
21339 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
21340 There is no such envvar since the inception of autom4te.cfg.
21341 * bin/autom4te.in (&parse_args): Uniquify `@include'.
21342 * bin/autoupdate.in: Adjust, and perform more control.

21344 * tests/autoconf: Dittowise.
21346 2001-08-31 Akim Demaille <akim@epita.fr>

21353 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
21355 2001-08-31 Akim Demaille <akim@epita.fr>

21358 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
21359 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
21360 installed peer executables, only PATH is allowed to resolve it.
21361 Pass `autoconf_dir' via options, not via invisible envvars.
21362 * lib/Autom4te/General.pm (&find_peer): Remove.
21363 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
21364 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
21365 * man/Makefile.am: Let help2man rely on PATH instead of trying to
21366 find the executables for it.
21367 * tests/Makefile.am: Major cleanup. Too lazy to document...
21368 * tests/atlocal.in: Remove all the obscure envvar manipulations.
21370 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
21371 indeed related to running the test suite, while passing
21372 --autoconf-dir and others is related to running non installed
21373 Autoconf executables. So don't do that, leave it to...
21374 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
21375 * tests/autoscan: New.
21376 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

21392 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
21393 Suggested by Paul Eggert.
21395 2001-08-29 Akim Demaille <akim@epita.fr>
21397 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
21398 download in a tmp dir.
21400 2001-08-29 Akim Demaille <akim@epita.fr>
21402 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

21414 * bin/autoconf.in: Simplify and adjust.
21415 * tests/Makefile.am (AUTOMAKE): Use --set.
21416 * tests/atlocal.in: Adjust.
21417 * BUGS: distcheck and check are weak.
21419 2001-08-29 Akim Demaille <akim@epita.fr>

21876 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
21877 don't waste time running `autoupdate --version' works.

21939 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
21941 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
21942 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
21943 * doc/autoconf.texi (C Compiler Characteristics): Update
21944 documentation for AC_C_BIGENDIAN.
21946 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
21948 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
21949 magic values from an object file when cross-compiling.
21950 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
21952 2001-08-10 Akim Demaille <akim@epita.fr>
21954 * bin/autom4te.in (&handle_output): Don't use `grep' with side
21956 Suggested by Russ Allbery.
21958 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
21960 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
21961 current $prefix to the sub-configures.
21963 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
21965 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
21966 extension (needed on BeOS). Reported by Guido van Rossum.
21968 2001-08-09 Akim Demaille <akim@epita.fr>
21970 * bin/autom4te.in ($icache): Load it only if older than autom4te.
21972 2001-08-07 Akim Demaille <akim@epita.fr>
21974 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
21976 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
21977 No need to remove the files before and after the each test, before
21978 each test and at the end of the suite is enough.
21979 Display only the children `times', not the shell's.
21980 If the test failed or was skipped, at-times is not available.
21982 2001-08-07 Akim Demaille <akim@epita.fr>
21984 Always produce testsuite.log, including when there are no
21985 failures. This helps getting information on skipped tests, and
21986 duration of the tests. Err, implement the latter btw.
21988 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
21989 Dump information on the first run of each test.
21990 (AT_CLEANUP): Create `at-times' containing the duration of the
21993 2001-08-07 Akim Demaille <akim@epita.fr>
21995 The use of `dumpstat' revealed that `len' was used although it
21996 should not. m4_text_wrap was using it, but in the Autoconf world
21997 where it is legal. Hence (i) test M4sh in its own world, not
21998 Autoconf's, and (ii), ahem, fix the bug :)
22000 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
22001 does not like `' instead of [].
22002 (AT_INIT): Forbid `^_?AT_'.
22003 And don't output such tokens.
22004 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
22005 `script.as', and `autom4te.cache'.
22006 Remove `empty' and `macro' which are no longer used.
22007 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
22008 * tests/m4sugar.at: Use it.
22009 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
22011 2001-08-07 Akim Demaille <akim@epita.fr>
22013 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
22015 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
22017 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
22019 2001-08-04 Akim Demaille <akim@epita.fr>
22021 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
22022 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
22024 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
22025 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
22026 (AC_F77_MAIN): Likewise.
22028 2001-08-04 Akim Demaille <akim@epita.fr>
22030 Don't rely on M4sugar outputting the patterns in files, since we
22031 might process the output _without_ running m4, hence without these
22034 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
22035 * bin/autom4te.in (@Request::includes): Remove, unused.
22036 (@Request::source): Rename as...
22037 (@Request::input): this.
22038 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
22039 (&handle_output): Fetch the patterns from the traces.
22040 `$forbidden' and `$allowed' are constant: use m//o.
22041 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
22042 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
22044 2001-08-04 Akim Demaille <akim@epita.fr>
22046 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
22047 autoconf', i.e., in addition to caching traces, cache the output.
22049 * bin/autom4te.in (Request::cache): Rename as...
22050 (Request::id): this.
22051 ($cache, $icache, $tcache, $ocache): New.
22052 (&handle_m4): Save M4 output in the cache instead of $tmp.
22053 (&handle_output): Adjust.
22054 (&up_to_date_p): Check that the output cache is up to date too.
22055 (top level): Run `&handle_m4' iff force or the cache is invalid.
22056 Run `&handle_output' if the output cache is more recent.
22058 2001-08-04 Akim Demaille <akim@epita.fr>
22060 * bin/autom4te.in ($force): New.
22061 (&parse_args, &print_usage): -f, --force is a new option.
22062 (&handle_output): CPP directives might have spaces after `#'.
22063 (&parse_args): The first file only can be frozen.
22065 2001-08-04 Akim Demaille <akim@epita.fr>
22067 Don't let autom4te compute the `include' traces several times:
22068 first check that the trace cache file is up to date, and then
22069 compare its timestamp with that of the output.
22071 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
22072 the preamble. Don't require 5.005 as Autom4te::General does it,
22073 and better yet (use `use', not `require'!).
22074 * lib/Autom4te/Struct.pm: Rename the last occurrences of
22075 Class::Struct as Autom4te::Struct.
22076 * lib/Autom4te/General.pm (File::stat): Use it.
22077 (&mtime): New, export it.
22078 * bin/autom4te.in: Use it.
22079 Declare `$req' is invalid if it is outdated.
22080 Don't declare it valid before saving it if something went wrong.
22082 2001-08-04 Akim Demaille <akim@epita.fr>
22084 Autom4te shall not encode Autoconf data, and preselecting traces
22085 must be proposed to the users.
22087 * bin/autom4te.in (@required_trace): Remove.
22089 (&parse_args, &print_usage): -p, --preselect is a new option.
22090 (&up_to_date_p): Adjust.
22091 * bin/autoconf.in: Preselect some Autoconf macros.
22093 2001-08-04 Akim Demaille <akim@epita.fr>
22095 * tests/tools.at (autoconf --trace: user macros): Check traces on
22096 macros invoked without arguments, and macros invoked with multiple
22099 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
22101 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
22104 2001-08-03 Akim Demaille <akim@epita.fr>
22106 * bin/autoconf.in ($@): Work around the usual sh bug.
22109 2001-08-03 Akim Demaille <akim@epita.fr>
22111 Clean up the handling of the M4 builtins tracing exception.
22113 * bin/autom4te.in (Request::request): Don't complete M4 builtins

22116 (@m4_builtin): this.
22117 (%m4_builtin_alternate_name): New.
22118 (&parse_args): Complete the trace requests with alternate names.

22130 (m4_divert_pop): Dump the whole diversion stack when a diversion
22132 * bin/autom4te.in (&handle_output): Remember of the first
22133 occurrence of a possibly undefined macro, not the last.
22134 Complain about the possibly undefined macros in the same order as
22135 the appear in the output.
22136 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
22137 * tests/tools.at (autoconf: forbidden tokens, basic)
22138 (autoconf: forbidden tokens, exceptions): No longer sort
22139 autoconf's stderr, as it is now deterministic.
22140 Check that `dnl' is caught.
22142 2001-08-01 Akim Demaille <akim@epita.fr>
22144 * configure.ac: Bump to 2.52c.

22161 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
22162 `END', as `Autom4te::General::END' will be triggered.
22163 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
22164 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
22165 system to run `mv', `rm', and `cmp'.
22167 2001-08-01 Akim Demaille <akim@epita.fr>
22169 * lib/Autom4te/General.pm (&unique): New.
