1120 Work around DJGPP shell function return bug with command substitutions.
1121 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
1122 shell function which also contains a command substitution causes
1123 the shell to barf. For more details and a fix see:
1124 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
1125 Possible workaround include putting the `return' in a subshell
1126 or calling another function to set the status.
1127 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE_BODY)
1128 (_AC_COMPILE_IFELSE_BODY, _AC_LINK_IFELSE_BODY)

1151 2009-09-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1153 DJGPP fix: remove both conftest and conftest.exe.
1154 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1155 and both `conftest' and `conftest.exe' with `-o conftest', but not
1156 with `-o conftest.exe'.
1157 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
1158 `conftest' without $ac_exeext suffix.
1160 DJGPP fix: do not try to source /dev/null as cache or site file.
1161 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
1162 load the cache or site file if it is `/dev/null', as DJGPP treats
1163 it as a regular file, but the shell then warns about it later.
1164 Fixes several test suite failures on DJGPP.

5980 Documentation improvements.
5981 * doc/autoconf.texi (Looping constructs): s/recurses/repeats/.
5982 (Evaluation Macros): Drop `1' suffix from metasyntax variable name
5983 that preceeds @dots. Improve wording.
5984 (Text processing Macros): Drop `1' suffix from metasyntax variable
5985 name that preceeds @dots.
5986 (Number processing Macros): Drop `1' suffix from metasyntax
5987 variable name that preceeds @dots. Improve wording.
5988 * lib/m4sugar/m4sugar.m4 (m4_cmp): Comment wording fix.
5989 Suggested by Ralf Wildenhues.
5991 2008-03-02 Jim Meyering <meyering@redhat.com>
5993 Don't infloop upon "make dist".
5994 * GNUmakefile: Merge from coreutils.
5995 * Makefile.am (dist-hook): Inject .tarball-version into tarball,
5997 * configure.ac (AC_INIT): Use .tarball-version, not .version.

6020 Cover more potentially problemtic file names. Use the new
6023 Properly handle funny file names for headers in config.status.
6024 The test suite did not cover this bug because the code was not
6025 quoting properly the arguments of `rm -f' (which "fails" silently)
6026 as well as the arguments of `diff' (whose output was redirected to
6027 /dev/null so we couldn't see its error message).
6028 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
6029 file names passed to `rm' and `diff'.
6030 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6031 Add a regression test.
6033 2008-03-01 Benoit Sigoure <tsuna@lrde.epita.fr>
6034 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6036 Properly expand @configure_input@ in config.status.
6037 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_MAIN_LOOP):
6038 Escape the backslashes and ampersands in $configure_input before
6039 using it in the sed replacement string to expand @configure_input@.
6040 Report by Eric Blake and Patrick Welche.
6042 2008-03-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6044 Ignore errors from ./run on w32.
6045 * tests/autotest.at (whitespace in absolute testdir):
6046 Ignore stderr for `./run' which fails to remove the
6047 busy test directory on w32.
6049 2008-02-22 Eric Blake <ebb9@byu.net>

6110 More corner cases in testsuite VAR=VALUE handling.
6111 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS): Fix quoting

6122 Fix regression in handling VAR=VALUE arguments to testsuite.
6123 * lib/autotest/general.m4 (AT_INIT) <PARSE_ARGS_END>: Detect

6140 not just when atconfig was located.
6142 Add 'testsuite -C dir'.
6143 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6145 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6147 <DEFAULTS>: Delay computation of variables based on $at_dir...
6148 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6149 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6150 <PARSE_ARGS>: Parse new option.
6151 <HELP_TUNING>: Document it.
6152 * tests/autotest.at (Choosing where testsuite is run): New test
6154 (Keywords and ranges): Add test for missing -k argument.
6155 * NEWS: Document this.
6156 * doc/autoconf.texi (testsuite Invocation): Likewise.
6158 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6160 * build-aux/config.guess, build-aux/config.sub,
6161 build-aux/texinfo.tex: Sync from gnulib.
6162 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
6165 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6167 * doc/autoconf.texi (Particular Programs): Do not mention the
6168 Autoconf version in which the AC_PROG_INSTALL change was done.
6169 Suggested by Paul Eggert.
6171 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6173 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6174 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6175 mode, we change to the source directory, also set $ac_pwd so we
6176 do not go back to the build tree for the next config subdir.
6177 * tests/torture.at (Deep Package): Extend test to contain two
6178 config subdirs on the top level.
6180 Fix parallel `maintainer-check'.
6181 * Makefile.am (maintainer-check-tests): Depend on `all'.
6182 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
6183 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
6185 (maintainer-check): Serialize the testsuite runs.
6187 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'

6209 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6211 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
6212 check_SCRIPTS. Building the wrappers for `all' allows help2man
6213 to use them for the manpages.
6214 Report by Benoit Sigoure.
6216 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
6218 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6220 Fix some write failure cases in Autotest.

6225 script executable if it is not complete.
6227 2007-12-12 Eric Blake <ebb9@byu.net>
6229 Fix thinko in earlier patch - m4_join isn't defined yet.
6230 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6231 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6232 (m4_require): Use m4_do, not m4_join.
6234 Fix some whitespace tests on cygwin.
6235 * tests/tools.at (autom4te and whitespace in file names): Restore
6236 font-lock. Create $TMPDIR before it might be used.
6238 Fix spurious testsuite failure with M4 1.4.11.
6239 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6241 Optimize AC_REQUIRE.
6242 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6243 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6244 (m4_require): Avoid extra macro calls.
6246 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6248 * tests/torture.at (srcdir): Fix quoting.
6250 Do not pass top_srcdir to configure scripts in testsuite.
6251 * tests/autotest.at (srcdir propagation): Copy install-sh to
6253 (my only test): Drop setting of `top_srcdir'.
6254 * tests/base.at (Input/Output): Likewise.
6255 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6256 config.guess, and config.sub to test source tree.
6257 Drop AC_CONFIG_AUX_DIR setting.
6258 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6259 * tests/torture.at (Substitute a 2000-byte string): Drop
6260 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6261 (Substitute a newline, datarootdir workaround): Likewise.
6262 (Define a newline): Adjust for linenumber changes in configure.ac.
6263 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6265 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6266 if `pwd` contains whitespace.
6268 Quote $abs_top_srcdir in tests.
6269 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
6270 * tests/tools.at (Syntax of the shell scripts): Likewise.
6272 * tests/m4sh.at (LINENO): Quote $0.
6274 Fix testsuite program wrapper for whitespace in `pwd`.
6275 The problem here is that the usual mantra is that command
6276 variables can contain arguments, thus we cannot just escape
6277 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6278 $top_builddir/tests directory early in $PATH, so that the
6279 wrappers are found by their plain name.
6280 * tests/wrapper.as: Put $testdir early in $PATH.
6281 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6283 Proper config.status --file/--header and $srcdir escaping.
6284 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
6285 characters in $ac_file_inputs.
6286 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
6288 * tests/torture.at (datarootdir workaround): Adjust.
6289 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
6291 Fix Autotest for whitespace in `pwd`.
6292 * lib/autotest/general.m4 (AT_INIT)
6293 <at_func_create_debugging_script, Driver Loop>:
6294 Quote $at_group_dir.
6295 * tests/autotest.at (whitespace in absolute testdir): New test.
6297 * lib/autom4te.in: Quote @datadir@.
6299 Proper file name escaping in Autoconf programs and Perl modules.
6300 This includes escaping of characters special to the shell
6301 as well as special to Perl, e.g., leading `<' or `>'.
6302 For example, when $file starts with `>', `open ">$file"'
6303 wrongly tries to append to a different file.
6304 * bin/autoconf.as: Fix quoting for autom4te options.
6305 * lib/Autom4te/General.pm (shell_quote): New function, taken
6306 from coreutils, written by Jim Meyering.
6308 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6310 * bin/autoreconf.in (parse_args): Likewise.
6311 * bin/autoscan.in (main): Likewise.
6312 * bin/autoupdate.in (main): Likewise.
6313 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
6314 * bin/ifnames.in: Likewise, XFile usage fixes.
6315 * tests/tools.at (autom4te and whitespace in file names): Extend
6316 test. Test twice, with special characters allowed on w32, and the
6317 rest. Test leading and trailing whitespace, for `open_quote'.
6318 (autotools and whitespace in file names): New, analogous test.
6319 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6320 by Russ Allbery and Eric Blake.
6323 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6324 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6325 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6326 (update_file, contents): Use it.
6328 * Makefile.am (autom4te-update): Rewrite for git.
6330 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6332 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6334 Fix copyright years.
6335 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6336 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6338 2007-12-04 Eric Blake <ebb9@byu.net>
6340 Manually resync with gnulib, since 'make cvs-update' no longer works.
6341 * build-aux/config.guess: New upstream version.
6342 * build-aux/config.sub: Likewise.
6344 When using older automake, don't downgrade build-aux/texinfo.tex.
6345 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
6346 * doc/Makefile.am (TEXINFO_TEX): Add.
6348 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6350 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6351 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6352 #undef as this runs afoul of our new way of creating config.h.
6353 Problem reported by Jim Meyering in
6354 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6356 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6358 Fix autom4te for unusual characters in input file names.
6359 * bin/autom4te.in (files_to_options): Quote active characters
6361 * tests/tools.at (autom4te and white space in file names):
6364 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6365 Document that Tru64 awk always splits $0.
6367 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6369 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6370 `#AT_STOP_...' line at the end of each test.
6372 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6374 * lib/autotest/general.m4 (AT_INIT): For awk line number
6375 extraction script, ensure `$at_group' has a defined value
6376 even for the empty set, and properly quote its usage inside
6379 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6381 * doc/autoconf.texi (Shell Functions): New chapter. Document
6382 IRIX sh $0 issue in functions, move content from ...
6383 (Portable Shell): ... here.
6384 (Shell Script Compiler): Note that shell functions are not
6385 totally unportable any more.
6387 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6388 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6390 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
6391 extracting the line numbers of the last needed test.
6393 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6395 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6398 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6400 Fix IRIX testsuite debugging failures: $0 in functions.
6401 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6402 Do not use $0 inside a function, as IRIX sh will set that to the
6403 function name rather than the script invocation name.
6405 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6406 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6408 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6409 to extract test scripts.
6410 (AT_INIT): Extract and cache test script line numbers.
6412 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6414 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6415 subsequent fixups; the awk -> here-document conversion trashes
6416 performance too much with AIX sh.
6418 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6420 * tests/local.at: Do not test m4, perl with AT_TESTED.
6422 Diagnose and guard against write errors dealing with config.status.
6423 The general idea is this: all write failures from `configure'
6424 writing `config.status' are indicated by $ac_write_error, which
6425 is only checked at the end. This is safe because config.status
6426 code is not executed before the file is complete. Other write
6427 failures, be they inside config.status, or in sub shell/awk
6428 scripts spawned from configure or config.status, typically need
6429 earlier checking, as their results are used right afterwards.
6430 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6431 before writing config.status, check afterwards.
6432 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6433 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6434 Set `ac_write_error' for write failures to config.status. Barf
6435 upon write failures to temporary files.
6436 Adjust note about closing and reopening the here-document.
6437 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6438 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6439 reopening the here-document.
6440 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6441 Ensure `ac_write_error' does not escape into config.status.
6442 Also, add a couple of code paths not yet exercised in the test
6443 suite: a config file with input from stdin, and a config header
6445 Suggestion for catching write errors by Bruno Haible.
6447 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6449 Avoid error with Tru64 awk and testsuite lines with many words.
6450 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6451 reads the testsuite, set the field separator to an unusual value,
6452 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6453 even splits the input if $i, i>0, was never accessed in the script.
6455 Revert 2007-10-17 change.
6456 * TODO: Multiline args in config files and headers mean something
6457 different and are not fixed, see
6458 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
6459 Report by Stepan Kasal.
6461 * doc/autoconf.texi (Generic Programs): Fix typo.
6463 2007-11-16 Stepan Kasal <kasal@ucw.cz>
6465 AC_*_TOOL does not canonicalize the prefix
6466 * doc/autoconf.texi (Generic Programs): Do not say that
6467 the *_TOOL macros canonicalize, they simply use the `host_alias'.

6471 Diagnose write errors in config.status instantiations.
6472 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
6473 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
6475 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6476 Extend test to also check for some write error failures, using...
6477 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
6478 Report by Bruno Haible.
6481 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

6485 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6487 Add witness macro for @top_build_prefix@ substitution.
6488 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
6489 (_AC_OUTPUT_FILE): Mention it here.
6491 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
6492 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6494 * lib/autotest/general.m4 (at_func_test): Remove.
6495 (AT_INIT): Pre-extract test groups into separate files.
6496 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
6497 Remove at-test-source files together with the $at_group_dir.
6498 * tests/autotest.at (Long test source lines): New test.
6500 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6502 Shell functions and variables may share a namespace.
6503 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
6506 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
6508 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
6511 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6513 * lib/autoconf/status.m4: Fix a couple of comment typos.
6515 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
6517 2007-11-13 Jim Meyering <meyering@redhat.com>
6519 Clean up the rule to create "expr".
6520 * tests/Makefile.am (expr): Don't redirect directly to target.
6521 Redirect just once, not for each echo statement.
6522 Use $@, not literal "expr".
6524 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
6526 Don't worry about preprocessor when testing long long.
6527 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
6528 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
6529 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6530 These no longer check for preprocessor flaws.
6531 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6532 Do not check for preprocessor flaws.
6534 2007-11-13 Jim Meyering <meyering@redhat.com>
6536 Adapt dependencies, now that a version change doesn't modify configure.ac
6537 * GNUmakefile: Remove "make clean" kludge.
6538 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
6540 Don't redirect directly to target.
6541 Use $@, not literal "version.m4".
6543 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6545 * doc/autoconf.texi (Making testsuite Scripts): Document
6546 ":;{" shorthand as in previous patch.
6548 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
6550 * doc/autoconf.texi (Limitations of Builtins): Document problem
6551 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
6553 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
6554 Use ":;{" shorthand.
6555 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6557 2007-11-12 Jim Meyering <meyering@redhat.com>
6559 Add more non-srcdir build support.
6560 * GNUmakefile (dummy): Split a long line.
6561 Add -v option to autoreconf invocation.
6563 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6564 * GNUmakefile (dummy): Remove INSTALL.
6566 Remove racy commands to build scripts in bin/ and tests/.
6567 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6568 are guaranteed to be built, remove the rules that tried to build
6569 them. Before, with a parallel build, these rules could lead to
6570 two processes writing tests/wrapper.in concurrently.
6572 Build in man/ only *after* building in bin/ and tests/.
6573 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6574 in both bin/ and tests/.
6576 Accommodate non-srcdir build-from-checkout.
6577 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6578 Use git's --git-dir=$srcdir/.git option.
6579 Add quotes, in case tarball_version_file contains shell meta-characters.
6580 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6581 * configure.ac: Pass "." to git-version-gen.
6583 Avoid spurious test failures due to version skew.
6584 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
6586 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6588 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
6589 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
6590 Remove conftest.dSYM directory.
6591 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
6592 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
6593 Remove `conftest.*' recursively.
6594 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
6595 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6597 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
6599 Report and analysis by Jeff Squyres and Peter O'Gorman.
6601 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
6603 Fix typos in variable names.
6604 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
6606 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
6608 Document that $((expression)) is not portable.
6609 * doc/autoconf.texi (Shell Substitutions): Here.
6611 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6613 Ignore configure --help* errors due to LINENO-impaired shells.
6614 * tests/torture.at (Configuring subdirectories, Deep Package):
6615 In the --help* tests in read-only trees, make `.' temporarily
6616 writable again for the `stderr' file, and ignore errors due to
6617 the attempt to write configure.lineno.
6618 Report by Patrick Welche.
6620 2007-11-10 Jim Meyering <meyering@redhat.com>
6622 Generate package.m4 in build-dir, not srcdir.
6623 * tests/Makefile.am (package.m4): Adjust target.
6624 Don't redirect directly to $@.
6625 (CLEANFILES): Add package.m4.
6626 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6628 When running $(AUTOTEST), search "." before searching $(srcdir).
6630 Avoid a race condition that would make parallel "distclean" fail.
6631 * tests/Makefile.am (distclean-generic): Replace the default,
6632 automake-provided rule with an identical one, but with an additional
6633 dependency on distclean-local. Simply adding the dependency would
6634 cause automake not to emit the rule at all.
6635 * BUGS: Building with -jN works, now.
6637 Distribute git-version-gen.
6638 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6639 since GNUmakefile is distributed, and requires it for dist* rules.
6641 Remove two more generated files from version control.
6642 * INSTALL: Remove generated file.
6643 * lib/autoscan/autoscan.list: Remove generated file.
6645 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6647 * GNUmakefile (PATH): Remove stray apostrophes; they become
6648 part of PATH, which isn't wanted here.
6650 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6652 New config files output variable `top_build_prefix'.
6653 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6655 * doc/autoconf.texi (Preset Output Variables): Document it.
6657 Report by Bob Friesenhahn.
6659 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6660 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6661 function, to parametrize arithmetic with expr vs. the shell.
6662 Use it where possible.
6663 Suggestion by Benoit Sigoure.
6665 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6667 Adjust the documentation of autotest WRT atlocal.
6668 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6669 when using Automake, to write a rule to produce atlocal, since it's
6670 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6671 distributed, not atconfig.in.
6673 2007-11-04 Eric Blake <ebb9@byu.net>
6675 Update list information.
6676 * README: Mention new autoconf-commit list.
6677 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
6679 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6681 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
6683 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6685 * build-aux/.gitignore: Ignore mkinstalldirs.
6687 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6689 2007-11-03 Jim Meyering <meyering@redhat.com>
6691 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6692 * build-aux/git-version-gen: This syncs from coreutils.
6694 Adjust the build procedure so "make check" works reliably.
6695 * README-hacking: Include an extra step between "make" and
6696 "make check" to ensure that the latter passes.
6698 Use just-built tools, when possible.
6699 * GNUmakefile (PATH): Set and export here, ...
6700 (dummy): ... rather than here.
6702 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6703 and Andreas Schwab <schwab@suse.de>
6705 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6708 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6710 * configure.ac (AC_PREREQ): Require version 2.60, for
6711 AC_PROG_SED, AC_PROG_GREP.
6713 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
6714 and Jim Meyering <meyering@redhat.com>
6715 and Andreas Schwab <schwab@suse.de>
6716 and Eric Blake <ebb9@byu.net>
6718 Document a bug in GNU Bash with compound commands and redirections.
6719 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
6720 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
6723 2007-11-03 Eric Blake <ebb9@byu.net>
6725 Support m4 1.4.5 in testsuite.
6726 * tests/torture.at (Define a newline): Exclude line numbers in
6728 Reported by Ralf Wildenhues.
6730 2007-11-03 Jim Meyering <meyering@redhat.com>
6732 Remove automake-provided files from version control.
6733 * build-aux/elisp-comp: Remove file.
6734 * build-aux/install-sh: Remove file.
6735 * build-aux/missing: Remove file.
6736 * build-aux/mdate-sh: Remove file.
6737 * build-aux/.gitignore: New file.
6738 Suggestion from Ralf Wildenhues.
6740 2007-11-03 Eric Blake <ebb9@byu.net>
6742 Adjust version comparison to account for git snapshot numbers.
6743 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
6744 component separator.
6745 * doc/autoconf.texi (Number processing Macros)
6746 <m4_version_compare>: Document this change.
6747 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6749 2007-10-30 Bruno Haible <bruno@clisp.org>
6751 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6752 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6753 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6754 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6755 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6756 Suggested by Paul Eggert.
6758 2007-10-28 Jim Meyering <meyering@redhat.com>
6760 * README-hacking: Autoconf, Automake, and Perl are required to build.
6761 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6763 2007-10-28 Jim Meyering <meyering@redhat.com>
6765 README-hacking: Recommend running autoreconf -vi.
6766 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6767 so that we use just-built tools when they're available.
6768 Suggestions from Ralf Wildenhues.
6770 2007-10-28 Jim Meyering <meyering@redhat.com>
6772 Make inter-release --version output more useful.
6774 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6775 which indicates that it is built using the 19th change set
6776 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6777 is a prefix of the commit SHA1.
6778 * build-aux/git-version-gen: New file.
6779 * configure.ac: Run it to set the version.
6780 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6781 * Makefile.am (dist-hook): Arrange so that .version appears only
6782 in distribution tarballs, never in a checked-out repository.
6783 * .gitignore: Add .version here, too. Just in case.
6784 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6785 not configure.ac, now that the version number changes automatically.
6787 Ensure that $(VERSION) is up to date for dist-related targets.
6788 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6789 git-version-gen doesn't match $(VERSION), but only for dist targets.
6791 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6793 Fix `Deep Package' failure with a configure script early in PATH
6794 * tests/torture.at (Deep Package): Add `.' early in PATH.
6795 Report by Jim Meyering.

6804 * README-hacking: New file: how to build from just-checked-out sources.
6806 2007-10-23 Eric Blake <ebb9@byu.net>
6808 Improve corner case of m4_expand.
6809 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

6812 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
6815 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
6817 * doc/make-stds.texi: Update from gnulib.
6819 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6820 and Eric Blake <ebb9@byu.net>
6822 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
6823 problem reported by Bruno Haible in
6824 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
6826 2007-10-22 Eric Blake <ebb9@byu.net>
6828 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6831 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6833 Don't check for bug in HP-UX 11.00 cpp.
6834 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6835 Use -1ull rather than -1u, since that causes problems with gnulib; see
6836 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
6838 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6854 escaping of backslash in here-documents.
6856 Fix `Deep Package' test failure on FreeBSD.
6857 * tests/torture.at (Deep Package): Do not add `.' to $PATH
6858 unnecessarily. Do not try running `/bin/sh configure' with a
6859 configure script to be found in $PATH, if the shell does not do
6860 this resolution. Fixes test failure on FreeBSD.
6862 Fix config header generation with AIX awk.
6863 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6864 script, use helper array D_is_set, as `" 0"' does not evaluate
6865 to true for AIX awk.
6867 2007-10-21 Eric Blake <ebb9@byu.net>

6902 * lib/autotest/general.m4 (BANNERS): New named diversion.
6903 (TESTS_END): Diversion no longer used.
6904 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
6905 shell function, which prints only as needed, using an associative
6906 array of banner text from a special diversion.
6907 <PARSE_ARGS_END>: No longer need awk to find banners.
6908 <TESTS>: Banners are no longer processed by main driver loop, so
6909 we no longer need case statement.
6910 (AT_BANNER): Rewrite to populate new diversion.
6911 (AT_SETUP): Each test invokes its own banner. No output is needed
6912 to the TESTS diversion.

6938 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Fix
6939 duplication bug by using new macro.
6940 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
6941 programs with stdin redirected, so programs that don't
6942 understand --version won't try to behave interactively.
6943 * tests/autotest.at (Tested programs): Catch this bug.
6944 * tests/m4sugar.at (m4@&t@_append): Test new macro.

8029 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
8031 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
8033 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
8034 'configure' will fail if the shell lacks proper support for shell

8045 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
8046 for a.* when searching for executables, as this prevents users
8047 from having files like a.c. Problem reported by Ralf Wildenhues in:

8059 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
8060 AC_CHECK_TYPE, AC_CHECK_TYPES.
8061 * doc/autoconf.texi (Generic types): C types must be type-names
8062 (the C terminology), not type-ids (the C++ term). C++ types
8063 must not be anonymous.
8064 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
8065 for C++; this drops support for anonymous struct and union types,
8066 which were problematic anyway.

8085 with objects too. Document the restrictions on its use.
8086 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8087 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8088 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8089 works but the latter doesn't, then it's a valid type.
8090 This lets people use function types and so forth.
8091 For C++ there doesn't seem to be a simple solution, so leave it alone.
8092 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8093 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8094 AC_CHECK_TYPE; that wasn't documented or necessary.
8096 2007-04-11 Stepan Kasal <kasal@ucw.cz>
8098 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

8149 2007-03-17 Jim Meyering <jim@meyering.net>
8151 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
8152 (Limitations of Usual Tools): Also list \< and \>, and mention that
8153 HP-UX's grep, like the one from Solaris, does not support that syntax.
8155 2007-03-09 Stepan Kasal <kasal@ucw.cz>
8157 * doc/autoconf.texi (Specifying Names): `--host' does not
8158 change the build type.

8264 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8265 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8266 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8267 substitution will still be done by the special code.

8291 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8292 early on the reader side, drop stderr of the input to avoid
8293 `broken pipe' error output; this may happen even with shell
8294 builtin `echo' of some bash versions. Reports by Ian Macdonald

8312 discussion about the allow_superuser_privileges example,
8313 and change it a bit to make things clearer.
8314 (Optimization and Wraparound): Clarify whether the compiler
8315 will generate an infinite loop for the example derived from
8316 Autoconf's mktime test.
8317 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8318 Also, clarify unsigned multiplication overflow.
8320 2007-01-04 Eric Blake <ebb9@byu.net>
8322 * bin/Makefile.am (RELEASE_YEAR): New macro.
8323 (edit): Use it to supply correct copyright year to scripts.

8334 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8335 feedback. The most important changes document what happens when
8336 you convert an out-of-range value to a signed integer type, and
8337 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8340 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8341 rewrite, taking notions from the recent discussion on the gcc and
8342 autoconf mailing lists; please see
8343 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8344 and follow the many links.

8347 (Signed Integer Division): New sections.
8349 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8351 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8352 preprocessor macro arguments in traced name.
8353 * doc/autoconf.texi (Defining symbols): Document longstanding
8354 support for AC_DEFINE-ing macros with arguments, and document
8355 behavior when the same variable has multiple AC_DEFINEs.
8356 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8357 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8358 macros directly, giving much shorter and simpler code.
8360 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8362 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8363 space before "$ac_configure_args" to prevent a 'config.status
8364 --recheck' failure if ac_configure_args doesn't contain a leading
8365 space. This works around a problem with the XEmacs configure.ac,
8366 which uses the (undocumented) ac_configure_args variable
8367 inconsistently with Autoconf.
8369 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8371 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8372 Include <limits.h>, and use its INT_MAX to rewrite the
8373 j loop so that it does not overflow 'int'. Problem reported by
8375 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8376 Play it safe by shifting left by 1 rather than multiplying by 2,
8377 as GCC is less likely to optimize this away when the value
8378 is signed (when it assumes overflow leads to undefined behavior).
8379 Also, don't assume time_t uses two's complement.
8381 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8383 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8384 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8385 dumps core on it. Report by Tim Rice.

8404 (External Software, Package Options): Cross-reference to Option
8405 Checking, and use this to shorten our section.
8406 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8407 "$x" to test "x$foo" != x.

8409 Don't warn if $enable_option_checking is "no".
8410 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8411 ac_unrecognized_opts to the empty string.
8412 Don't echo the unrecognized opts, as this might mishandle
8413 backslashes or leading -.

8415 usage next to the other --disable-FEATURE options in the

8420 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

8422 Print warning for unrecognized --with and --enable options
8423 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8424 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8425 Disable option checking when subdirs are configured.

8427 unrecognized --with and --enable options at the end of
8428 the configure output (as well as at the beginning).
8429 * doc/autoconf.texi (Option Checking): New node.
8430 Document new option warning functionality.

8437 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8439 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8440 Define HAVE_GETMNTENT to 1, not to the empty string.
8441 Problem originally reported by Jochen Friedrich in
8442 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8444 This change prompted by a problem report by Andrey Simonenko in
8445 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8446 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8447 object-like macros only, in the traditional portable character
8449 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8450 Warn about attempts to define things that are not identifiers.
8451 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8452 awful hack that AC_DEFINEd macro names containing parentheses.
8454 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8456 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8457 too drastic, even if Texinfo in theory requires it for info mode.
8459 (config.status Invocation): Renamed back from Recreating a
8461 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8462 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8464 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8466 * NEWS: Version 2.61a.
8468 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8469 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8471 * NEWS: Document changes with echo and printf, and the lack
8472 of limits on the total size of multi-line values of substituted
8473 variables, and the AC_FUNC_FSEEKO fix.
8475 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8477 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8478 Writing configure.ac.
8479 (Autoconf Input Layout): Renamed from configure.ac Layout.
8480 (Recreating a Configuration): Renamed from config.status Invocation.
8481 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8482 (acconfig Header): Renamed from acconfig.h.
8483 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8484 (Writing Testsuites): Renamed from Writing testsuite.at.
8485 (Autom4te Cache): Renamed from autom4te.cache.
8487 * BUGS: Remove mention of VPATH problem, since it's now documented
8488 not to be a bug in the Autoconf build procedure itself, but rather
8489 a problem with the proprietary `make' programs.
8491 * doc/autoconf.texi (Build Directories): Add a cross reference
8494 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8495 * doc/standards.texi: Sync from gnulib.
8497 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8498 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8499 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8500 generated automatically.
8502 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8504 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8505 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8506 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8508 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8510 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8511 `CEOF$ac_eof' special marker, the awk script cannot contain a
8512 line matching `^CEOF', so this is not needed any more.
8513 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8514 special marker in the test.
8516 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8518 * tests/tools.at (autom4te preselections): Use `find -newer';
8519 remove one of the sleeps.
8521 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8522 more readable, using ...
8523 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8525 * doc/autoconf.texi (autoheader Invocation): Do not double-
8526 quote the parameter of `AH_BOTTOM' in the example.
8528 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8530 * doc/autoconf.texi (Configuration Headers): Remove the
8531 example with multiple input files.
8532 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8533 multiple input files.
8535 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8537 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8538 creating the awk substitution script, handle one input line at a
8539 time, so that the maximum length of a substituted (multi-line)
8540 value is not limited by the size of the sed pattern space.
8541 The trade-off is a slightly repetitive sed script.
8542 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8543 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8544 * tests/torture.at (Substitute a 2000-byte string): Increase the
8545 test with several long lines, they should not be caught by sed
8548 * tests/tools.at (autom4te preselections): New test, to flag
8549 entries missing from autom4te.cfg.
8550 Report by David Byron <dbyron@hheld.com>.
8552 * tests/torture.at (Substitute a 2000-byte string): Actually use
8553 AC_PROG_AWK, so the last change works as intended.
8554 (Substitute and define special characters): Likewise.
8555 (Substitute a newline): Likewise.
8557 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8558 instead of `awk' consistently.
8559 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8560 * tests/torture.at (Torturing config.status): Test both the
8561 result of AC_PROG_AWK and plain awk.
8562 (Substitute a 2000-byte string): Likewise.
8563 (Substitute and define special characters): Likewise.
8564 (Substitute a newline): Likewise.
8566 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8568 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8569 can be assigned to a function pointer. Problem reported by
8570 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8571 part of a patch by Ralf Wildenhues in that same bug report.
8573 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8575 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8576 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8578 2006-12-01 Eric Blake <ebb9@byu.net>
8580 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8581 cross-compiling from cygwin to mingw.
8582 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8583 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8584 to lib/autoconf/c.m4.
8586 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8588 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8589 string for more reliable failure. Wrap the entire test that
8590 causes the broken Solaris printf to dump core, in a subshell,
8591 so the segmentation fault message is reliably suppressed.
8592 Fix shell expansion errors by using /usr/ucb/echo always;
8593 avoid an error on systems without it by another subshell.
8594 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8595 subshell-$as_echo to `as_echo', for better error message.
8597 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8599 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8600 `BASH_SOURCE' contain a newline, set them to empty, as they may
8603 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8605 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8606 years and is too hard to maintain now. The last straw was
8607 reported by Jerker Baeck in
8608 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8609 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8610 * doc/autoconf.texi (Particular Functions): Move
8611 AC_FUNC_SETVBUF_REVERSED from here...
8612 (Obsolete Macros): ... to here. Say that it does nothing now.
8613 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8614 Turn into (almost) a no-op.
8616 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8618 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8619 These macros are obsolescent and new applications shouldn't need them.
8620 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8621 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
8622 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
8623 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8624 (AC_FUNC_VPRINTF): Likewise.
8625 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
8626 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
8627 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8629 * doc/autoconf.texi (Setting Output Variables): Mention that
8630 @VAR1@VAR2 has unspecified behavior. Problem reported by
8632 * NEWS: Mention this.
8634 * Makefile.am: Put only a single '#' into the copyright notice,
8635 so that it's also present in the output file. Standardize wording
8636 in makefile copyright notices to match GNU coding standards.
8637 * bin/Makefile.am: Likewise.
8638 * doc/Makefile.am: Likewise.
8639 * lib/Makefile.am: Likewise.
8640 * lib/freeze.mk: Likewise.
8641 * lib/autoconf/Makefile.am: Likewise.
8642 * lib/autoscan/Makefile.am: Likewise.
8643 * lib/autotest/Makefile.am: Likewise.
8644 * lib/m4sugar/Makefile.am: Likewise.
8645 * man/Makefile.am: Likewise.
8646 * tests/Makefile.am: Likewise.
8647 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
8650 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8652 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8653 in the sed script that mangles the awk script: delete up to the
8654 first exclamation mark only.
8655 * tests/torture.at (Substitute and define special characters):
8658 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8660 Rewrite config files generation: avoid quadratic growth in
8661 the number of substituted variables by using awk instead of sed
8662 for the bulk of the substitutions.
8663 * NEWS: Mention this.
8664 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8665 forbidden in the output (and thus input) file.
8666 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8667 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8668 generate just one large awk script for substitutions,
8669 eliminating much of the earlier complexity, while adding some
8670 new complexity. Only expand the substitution templates at
8671 configure time, for smaller configure script size. If
8672 _AC_SUBST_FILES are used, test 'awk' for working getline support
8673 at config.status time. If absent, interpolate through the
8674 shell. The awk script was written with much help
8675 from Paolo Bonzini and Paul Eggert.
8676 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8677 (_AC_SED_FRAG_NUM): Likewise.
8678 (_AC_SUBST_CMDS): Renamed from...
8679 (_AC_SED_CMDS): ...this.
8680 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8681 * tests/torture.at (Substitute a 2000-byte string): Also
8682 substitute a line with 1000 words, and a variable with several
8684 (Substitute and define special characters): Test awk special
8685 characters, and put substitution input strings `@foo@' in the
8686 output, to test that no recursion happens; test several other
8687 combinations from Paolo Bonzini.
8689 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8691 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8692 that replaced echo with AS_ECHO where this wasn't necessary.
8693 Problem reportd by Ralf Wildenhues.
8694 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8695 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8696 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8698 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8700 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8702 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8704 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8705 that traditional Awk lacks 3-arg "split". It has it.
8706 Mention that FS must be a single character, and a few other
8707 99-byte limits of traditional Awk.
8708 Mention that if (i in a) doesn't work with traditional Awk.
8710 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
8712 * tests/autotest.at (BSx641-newline in command):
8713 (BS-BS-newline in command, BSx640-newline in command):
8714 (Newline-CODE-BS-newline in command):
8715 (Single-quote-BS-newline in command):
8716 (Single-quote-newline-BS-newline in command):
8717 Use printf '%s\n' instead of echo, for portability to hosts
8718 where echo interprets backslashes. This will break on hosts
8719 that lack printf, but for now let's assume all such hosts
8720 are dead (if not, we should get reports of test failures).
8722 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8724 'echo' has some portability problems, when given a first argument
8725 with a leading '-', or when given any argument containing '\'.
8726 Avoid using 'echo' in these cases.
8727 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
8728 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
8729 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8730 * lib/autotest/general.m4 (AT_INIT): Likewise.
8731 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
8732 argument might be unportable.
8733 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
8734 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
8735 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
8736 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
8737 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
8738 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
8739 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
8740 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
8741 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
8742 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
8743 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
8744 (AC_PROG_MAKE_SET): Likewise.
8745 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
8746 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
8747 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
8748 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
8749 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
8750 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
8751 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
8752 * bin/autoconf.as: Redo verbose flag implementation, as the old
8753 scheme wouldn't work with AS_ECHO.
8754 * lib/autotest/general.m4 (AT_INIT): Likewise.
8755 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8756 Don't use ECHO_T, since ECHO_N is now reliable.
8757 * lib/autotest/general.m4 (AT_INIT): Likewise.
8758 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8759 rather than using a here-document to put the script into a file.
8760 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8762 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8763 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8764 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8765 bug, but we might as well stop using ECHO_N and ECHO_C internally.
8766 * lib/autotest/general.m4 (AT_SETUP): Likewise.
8767 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
8768 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8769 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
8770 operand, as AS_ECHO requires. Avoid double file name expansion.
8771 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8772 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8773 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8774 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8775 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8776 Double-quote strings that would otherwise contain M4 comments.
8777 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8779 * configure.ac (AC_INIT): Bump to 2.61a.
8782 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8786 * configure.ac (AC_INIT): Bump to 2.61.
8789 * tests/autotest.at (Macro with backslash in a test title):
8790 Comment out for now, as this tests neither fails nor passes
8791 reliably. Problem reported by Ralf Wildenhues.
8793 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8795 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8796 in previous change, which caused test failures.
8798 2006-11-16 Stepan Kasal <kasal@ucw.cz>
8800 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
8801 code for --enable, --disable, --with, and --without to...
8802 (_AC_INIT_PARSE_ENABLE): ... a new macro.
8803 * doc/autoconf.texi (Package Options):
8804 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
8806 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8808 Import these changes from config via gnulib:
8810 2006-11-15 Ben Elliston <bje@gnu.org>

8835 2006-11-15 Karl Berry <karl@gnu.org>
8837 * standards.texi: core -> memory, throughout.
8838 (CPU Portability): show correct example of calling write
8839 on a char value; thanks to Paul Eggert for the code.
8840 Both of these suggestions from Eugene Y. Vasserman.
8843 Import these changes from texinfo via gnulib:
8845 2006-11-08 Karl Berry <karl@gnu.org>

8855 2006-11-13 Paul Eggert <eggert@cs.ucla.edu>
8857 * NEWS: Document the AC_ARG_WITH change.
8859 2006-11-13 Bruno Haible <bruno@clisp.org>
8861 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): For --with, --without
8862 options, transliterate also dots to underscores.

8865 first argument may also contain dots.
8867 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
8869 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
8870 benefit of platforms like Solaris+GCC where it is common to have a
8871 non-working g++ installation.
8873 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8874 and Joel E. Denny <jdenny@ces.clemson.edu>
8875 and Paul Eggert <eggert@cs.ucla.edu>

8878 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
8881 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8883 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set

8906 and Stepan Kasal <kasal@ucw.cz>
8908 Handle special characters in test case titles correctly.
8909 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
8911 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
8912 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
8913 argument. Extend to check titles printed by ./micro-suite and
8914 ./micro-suite -l and the title in micro-suite.log.
8915 (Backquote in a test title,
8916 Single-quote in a test title,
8917 Double-quote in a test title): Don't expect failure anymore.
8918 (Backslash in a test title): Put a non-whitespace character after the
8919 backslash so that Bourne shells might actually see it as an escape
8921 (Brackets in a test title,
8922 Pound in a test title,
8923 Comma in a test title,
8924 Quoted Macro in a test title,

8928 Macro with double-quote in a test title,
8929 Macro with backslash in a test title): New tests expected to fail.
8930 * tests/torture.at (#define header templates): M4-quote this title in
8931 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
8932 The visible effect was a stray [] in the testsuite output.
8934 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8936 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8937 `trap ... 0' inside a function, for AIX sh.
8939 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8941 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8942 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8943 5363) simply issues a warning when dividing by zero at compile
8944 time. Problem reported by Elias Pipping.
8946 2006-10-26 Eric Blake <ebb9@byu.net>
8949 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8950 show effect on macros that expand with commas.

8978 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8979 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8980 reported by Nelson H. F. Beebe for Coreutils 6.4.
8982 * tests/tools.at (autoconf --trace: user macros): Remove test
8983 for tracing multiline macros, since m4 1.4.7a uses a different
8984 way to number lines. Problem reported by Ralf Wildenhues.
8986 2006-10-24 Stepan Kasal <kasal@ucw.cz>

9060 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9062 (Imported from Automake.)
9063 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9064 which incorrectly sets the mode of an existing destination
9065 directory. In some cases the unpatched install-sh could do the
9066 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9067 system. We hope this is rare in practice, but it's clearly worth
9068 fixing. Problem reported by Alex Unleashed in
9069 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9070 Also, don't bother to check for -m bugs unless we're using -m;
9071 suggested by Stepan Kasal.

9120 added to the template can get mangled.
9122 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9124 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9125 include the default headers, and redefine obstack_chunk_alloc
9126 and obstack_chunk_free. Fixes false failure with glibc.

9145 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9147 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9148 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9149 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9150 Use a better substitute, by inspecting the output of "ls"
9151 rather than just using ":".
9152 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9153 rather than AS_EXECUTABLE_P, since we needn't worry about
9154 non-regular files here.
9156 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9157 due to configuration hassles with this. See Tonya Underwood's report

9170 initialization which is not inherited through the environment
9171 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

9181 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9182 comment about ac_cpp_err; it was incorrect, and anyway
9183 ac_cpp_err is being removed below.
9184 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9185 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9186 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9188 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9189 with werror_flag and conftest.err and so forth. This is more
9190 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9191 and anyway the user shouldn't normally want to see this gorp logged.
9192 Problem reported by Ralf Wildenhues.
9193 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9194 empty, not 'no', since the rest of the code uses 'test -z'.

9198 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9199 Use a single call to AC_DO_TOKENS rather than multiple, for
9201 (_AC_LINK_IFELSE): Test that resulting file is executable.
9202 Problem reported by mwoehlke in
9203 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9205 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9206 than creating a file to use with test -x; this is much faster.
9208 2006-10-02 Bruno Haible <bruno@clisp.org>
9210 * lib/autom4te.in (Automake-preselections): Add
9211 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9213 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9215 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

9220 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

9222 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9223 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9224 still doesn't let the program compile.
9225 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9228 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9229 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9230 include it, without including anything else.
9231 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9233 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

9250 values. Problem reported by Ralf Wildenhues.

9412 except the first two arguments are reversed.
9413 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

9464 didn't work if some values were cached but not others. Test for
9465 broken lex libraries like native ia64-hp-hpux11.22; see
9466 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
9467 work around the problem by preferring an empty LEXLIB to -lfl or

9698 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9699 more globally, since the 2006-06-30 patch didn't suffice. Problem
9700 reported by Keith Marshall. Also, don't bother with builddir2,
9701 since it shouldn't be needed any more.
9703 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

9724 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9725 Require that long long int be at least 64 bits wide. C99 requires
9726 this and enough programs depend on it so we should check for it.

9740 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9742 * doc/autoconf.texi: Be more consistent about using @acronym with
9743 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9744 quite right (it talked about "OSF/Tru64", even though the
9745 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9746 and it even mentioned "OSF 4"!) and at this point there's little
9747 reason to talk about OSF any more, since it died in 1994.
9748 (Specific Compiler Characteristics): Simplify example of
9749 negative-size array.
9750 (File Descriptors): Reorder to make the text flow better.
9751 Remove joke about "appreciate the various levels"; I didn't get it.

9755 Tone down the advice against renaming or removing open files.
9756 (Limitations of Usual Tools): Add a new section, on 'rm'.
9758 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9760 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9761 -lXt in LIBS, idea from Karsten Hopp; this was due since
9764 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9765 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9766 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9767 (which belong to Xt, not X itself). See Debian bug 327655.

9816 Use @acronym around BSD, GCC, and GNU when appropriate.
9817 (Why GNU M4): Renamed from "Why GNU m4".
9818 (Redefined M4 Macros): Mention that Posix
9819 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9820 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9823 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9825 * bin/autom4te.in (handle_output): Do not forbid the empty
9827 * tests/tools.at (autoconf: the empty token): New test.
9829 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9831 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9832 calls, so that we do not care whether they are LIFO or FIFO;
9833 in the m4_wrap, do not check which diversion is the topmost
9834 one, just check that the stack is balanced at the end.
9835 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9836 base diversion forever--pop the previous diversion before
9837 opening the new one; consequently, remove the m4_wrap call.
9838 * lib/autotest/general.m4 (AT_INIT): Likewise.
9839 * tests/m4sugar.at: Do not use
9840 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
9842 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
9843 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9845 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9846 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9847 Rework example of m4wrap token-pasting trouble so that it doesn't
9848 care whether it's LIFO or FIFO.
9849 Fix some "contrary to"s that are awkward in English.
9851 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9853 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9854 to `yes' instead of `int$1_t' if the type is found, for more
9855 consistent configure output (where $1 is the number of bits).
9856 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9857 Suggested by Bruno Haible.
9859 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9860 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9861 with system headers. Report by Bruno Haible.
9863 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9865 * config/config.guess, config/config.sub: Sync from upstream.
9867 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9868 in order to avoid picking up an older installed frozen m4sh.m4f.
9869 Besides an outdated shell startup, this could have been created
9870 by an earlier M4 version with incompatible frozen file format.
9872 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9874 * README: Recommend m4 1.4.4 instead of 1.4.3..
9875 * doc/autoconf.texi: Likewise.
9876 (Special Chars in Names): Say that $(.FOO) is portable, as
9877 suggested by Stepan Kasal.
9878 (Installation Directory Variables, Build Directories):
9879 (Automatic Remaking, Subdirectories, Fortran Compiler):
9880 (Making testsuite Scripts, Defining Directories):
9881 Quote variable usages better.
9882 (Making testsuite Scripts): Add clean-local rule to makefile
9883 snippet, by Eric Blake.
9884 (Installation Directory Variables): Fix table item font.
9885 Reword slightly to clarify. Generalize advice about
9886 not using special characters to include all file-related
9887 vars, not just VPATH.
9888 (Special Chars in Variables): Warn about special characters in
9890 (Assignments): Clarify default-value example as suggested by
9892 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9893 (Special Shell Variables): Note leading ./ or ../, as suggested
9895 (Limitations of Builtins): Under cd, warn about CDPATH.
9896 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9899 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9901 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9902 `@var', for texi2html.
9903 (Systemology): Some more word wrapping, for DVI output.
9904 (autom4te Invocation): The short option for `--melt' is `-M',
9907 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9909 * doc/autoconf.texi: More formatting and English tweaks,
9910 many suggested by Ralf Wildenhues.
9911 Reword to avoid "@code{...}'s" and the like, since it's ugly
9912 with Emacs info mode. discontents -> woes.
9913 Put a few "will"s back. time stamp -> timestamp.
9914 side-effect -> side effect.
9916 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9918 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9919 Warn about $@ not persisting. Problem reported by Julien Danjou in
9920 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9921 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9922 Mention other special chars, too.
9924 2006-06-14 Eric Blake <ebb9@byu.net>
9926 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9928 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9930 * doc/autoconf.texi: Some systematic minor improvements, as
9931 follows. Use "makefile" when talking about makefiles
9932 generally (which might be named "makefile" or "Makefile" or even
9933 "foo.mk"), "Makefile" when talking about a specific makefile
9934 called "Makefile". This unclutters the text from weird quotes
9935 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9936 values" rather than "@var{foo}s" and similar constructs containing
9937 "}s". Use "Make rules" rather than "Makefile rules". Minor
9938 English-language improvements. Change the prefix "sub-" to "sub"
9940 Put blank lines around examples more consistently.
9941 Avoid "rather" and "very" as intensifiers.
9942 Avoid "will" as an auxiliary.
9943 (Limitations of Make): Split this node into....
9944 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9945 (Leading _ in Macro Names, Backslash-Newline-Newline):
9946 (Backslash-Newline Comments, Long Lines in Makefiles):
9947 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9948 (obj/ and Make, make -k Status, VPATH and Make):
9949 (VPATH and Double-colon, $< in Explicit Rules):
9950 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9951 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9952 New nodes, resulting from splitup of Limitations of Make.
9953 All cross-references changed. Raise the top node from
9954 a section to a chapter, and all subnodes accordingly.
9955 Redo the introductory wording to match the new organization.
9956 (Installation Directory Variables): Use an example that is
9957 closer to what Autoconf actually does. Mention that VPATH's
9958 value should not contain metacharacters or white space.
9959 (Fortran Compiler): Fix a VPATH bug in an example.
9960 (Leading _ in Macro Names): Mention that this problem is no longer
9961 of practical concern.
9962 (VPATH and Make): Reword the advice to make it clearer
9963 that Autoconf and Automake support VPATH in non-GNU make, but
9964 many packages have bugs in this area.
9965 ($< in Explicit Rules): Refer to Build Directories rather
9966 than using a (non-VPATH-safe) example.
9967 (Automatic Rule Rewriting): Mention the sort of disaster that
9968 can ensue with Solaris-style rule rewriting with VPATH.
9970 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9972 * doc/install.texi (Compilers and Options): Weaken the
9973 suggestion to use GNU make for VPATH builds.
9975 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9976 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9978 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9979 in regular expression.
9981 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9983 * doc/autoconf.texi (Installation Directory Variables):
9984 Drop extra @samp from `@table @samp' item.
9985 (Limitations of Usual Tools): Comment fix.
9986 Do not nest @samp just to point to other table items.
9987 (Writing testsuite.at) <AT_CHECK>: The second argument to
9988 `@dvar' is already @samp'ed.
9989 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9990 do not use @var in the second argument.
9992 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9994 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9995 $as_shell.exe too. Problem reported by Andreas Buening in
9996 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9998 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10000 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10001 `unused variable' compiler warning, for `-Wall -Werror'.
10002 Reported by Jaap Haitsma in
10003 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10005 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10007 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10008 case the compiler dumps core. Problem reported for
10009 OpenServer 5.0.7 by Tim Rice in
10010 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10011 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10014 2006-06-06 Tim Rice <tim@multitalents.net>.
10016 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10017 "ERROR" only shows up in "make check" output if there is an
10020 2006-06-06 Eric Blake <ebb9@byu.net>
10022 * tests/tools.at (automatically allowed tokens): Fix typo.
10024 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10026 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10028 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10029 typically overflows on x86 CPUs, even though the C standard
10030 requires otherwise.
10032 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10034 * configure.ac (AC_INIT): Bump to 2.59e.
10037 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10041 * config/texinfo.tex: Sync from upstream.
10043 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10044 seen, invoke libtoolize with `--ltdl' argument.
10045 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10047 Suggested by Eric Blake.
10049 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10051 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10052 reported by Ralf Wildenhues.

10061 * doc/autoconf.texi: Modernize some of the references to Solaris.
10063 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10065 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10066 message issued by AC_REQUIRE.
10067 * tests/m4sugar.at: Check m4_require's error message.
10068 * tests/base.at: Check AC_REQUIRE's error message.
10069 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10071 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10073 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10074 `expout' as the last parameter.
10075 * tests/tools.at: Adapt to the above change.
10077 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10079 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10080 information about race-free implementations of mkdir.
10082 2006-06-04 Eric Blake <ebb9@byu.net>
10084 * bin/autoreconf.in (help): Document M4 environment variable.
10085 * bin/autoconf.as (Usage): Likewise.

10089 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10091 * NEWS: GNU make now recommended for VPATH builds.
10092 Mention that some macros are now documented to be obsolescent.
10093 * doc/autoconf.texi:
10094 Prefer "current" to "modern" to describe
10095 currently-used (albeit perhaps old-fashioned) hosts.
10096 Mention which ancient features no longer need to be worried about.
10097 setgid -> set-group-ID
10098 setuid -> set-user-ID (these are the Posix terms)
10099 Fix some misuses of "only".
10100 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10101 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10102 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

10109 Mention that these macros are obsolescent.
10110 (Installation Directory Variables): shall -> should
10111 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10112 Mention that it's now safe to use 3 and 4.
10113 (Limitations of Usual Tools): cp -r is now specified by Posix.
10114 Omit longwinded and obsolescent discussion of cp -f.
10115 Modernize discussion of expr, ls.
10116 (Limitations of Make): Modernize discussion of VPATH builds.
10117 Mention $? as a workaround in some cases.
10118 * doc/install.texi (Basic Installation):
10119 Mention "./configure; make; make install" first. Be more
10120 specific about why this file is generic. Remove unnecessary
10121 parens. Remove misleading "only". Remove obsolete advice
10122 about csh. Don't say "configure" takes awhile; say it
10123 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10124 and CC=c99 rather than CC=c89, as these are blessed by current
10125 Posix. Recommend GNU make if doing a VPATH build.
10127 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10129 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10130 examples involving shell prompts.

10133 and Paul Eggert <eggert@cs.ucla.edu>
10135 * doc/autoconf.texi (Here-Documents): Add details about the
10136 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10137 use "here-documents" instead of "here documents".
10139 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10141 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
10143 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>

10148 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10150 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10151 about quoting the case statement, just in case.
10152 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10153 was fixed in ksh93g; reported by Ralf Wildenhues.
10155 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10157 * doc/autoconf.texi (System Services): Do not document

10159 (Particular Programs) <AC_PROG_MKDIR_P>:
10160 Document that ${MKDIR_P} understands --.

10167 argument with leading hyphen. Problem reported by Paul Eggert.
10169 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10171 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10172 about quoting ac_try: quote all of it, if any of it seems suspicious.
10173 This means we don't have to worry about ${ or sed any more.
10174 Also, double-quote the case statement, to work around misuses via
10175 underquoting as reported by Ralf Wildenhues in
10176 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10177 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10178 undocumented and dangerous macro.

10186 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10188 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10190 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10191 since evidently some packages rely on the old, broken behavior.
10192 Problem reported by Ralf Wildenhues in
10193 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10194 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10195 pre-2006-05-26 definitions, but leave in the comments that
10196 these macros are dangerous and should not be used.
10197 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10198 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10199 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10200 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10201 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10203 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10205 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10206 the use of 'tr', since this is our only use of 'tr'.
10208 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10209 and Paul Eggert <eggert@cs.ucla.edu>
10211 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10212 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10214 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10216 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10217 the output file in the `${datarootdir}' test.
10219 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10220 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10222 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10223 mention of `datarootdir' in the input file(s), but literal
10224 `${datarootdir}' in the output file, and we haven't warned yet,
10225 then warn as well: the user may have (erroneously) used
10226 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10227 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10228 * tests/torture.at (datarootdir workaround): Extend this test.
10231 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10232 and Paul Eggert <eggert@cs.ucla.edu>
10234 * doc/autoconf.texi (autoheader Invocation): The first argument to
10235 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10236 alternatives and clear up the language a bit.
10238 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10240 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10241 ac_config_guess, ac_config_sub, ac_configure.
10242 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10243 Fix typo that prevented an unnecessary space from being removed.
10244 Problems reported by Ralf Wildenhues in:
10245 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10247 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10249 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10250 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10251 Don't use the term "thread-safe" to talk about mkdir race
10252 conditions, since the problem is more a process than a thread
10253 issue. Problem reported by Stepan Kasal in:
10254 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10255 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10256 the test for 'install' more closely. Look at MKDIR_P first.
10257 Look in the PATH, and at /opt/sfw/bin.
10258 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10259 Don't bother to try mkdir -p, since we already check mkdir --version;
10260 just look at the version number. (There's no easy way to check
10261 for race-free implementations.)
10262 * tests/tools.at (autoconf: subdirectories): Adjust to above
10263 changes, since MKDIR_P now might end in "/mkdir -p".
10265 * doc/autoconf.texi (autoheader Invocation): Mention that the
10266 first arg of AC_DEFINE_UNQUOTED must be a literal.
10267 Problem reported by Ben Pfaff in
10268 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10270 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10271 * doc/autoconf.texi (Special Chars in Variables): New section.
10272 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10273 (Installation Directory Variables): Quote $(datadir) better.
10274 (Limitations of Builtins): Describe some of eval's trickiness.
10276 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10277 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10278 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10279 in front of every arg, not just trailing args. Quote apostrophes.
10280 (_AC_EVAL_ECHO): New macro.
10281 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10282 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10284 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10285 exposed by quoting of eval argument. Put the command on line line
10287 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10288 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10289 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10290 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10291 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10292 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10293 Use eval more safely.
10294 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10295 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10297 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10298 lines, exposed by quoting of eval argument.
10300 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10301 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10303 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10304 initialization of `ac_cv_exeext', do not override it if it was
10305 already set, unless it was set to `no', for compatibility with
10306 Autoconf-2.13, and comment this.
10307 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10308 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10309 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10310 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10311 Document that this test may be overridden by setting
10314 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10316 Revert these two patches:
10318 2006-04-06 Eric Blake <ebb9@byu.net>
10319 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10320 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10323 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10324 Clean up _AC_COMPILER_EXEEXT* macros.
10325 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10326 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10327 ac_file to the name of the default output file and call
10328 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10329 initial `rm' of the candidate files...
10330 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10331 the same list in subsequent `rm' calls, and for the temporary
10332 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10333 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10334 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10335 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10336 no longer needed) by libtool. Make it a cache check.
10337 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10338 copied here by mistake.
10339 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10340 _AC_COMPILER_EXEEXT.
10341 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10342 _AC_COMPILER_OBJEXT directly.
10343 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10345 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10347 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10348 Fix description of how the buggy `sed' works.
10350 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10352 Sync from Automake:
10354 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10355 ENOLCK. Only mention `make -j' when applicable. Only raise
10356 fatal errors when `make -j' is involved. Improve error message.
10358 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10360 * doc/autoconf.texi (Here-Documents): We now know more about
10361 the variable expansion in here documents bug.
10362 Thanks to Tim Rice and Stepan Kasal.
10364 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10365 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10367 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10369 * tests/autotest.at (Multiline command from M4 expansion):
10370 No failure to be expected if the shell quotes newlines in
10371 commands in the `set -x' output. Report by Tim Rice.
10374 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10376 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10377 expansion in the here-documents used by config.status, as that
10378 runs afoul of the Korn shell version M-12/28/93d bug described in
10379 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10380 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10381 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10383 2006-05-23 Jim Meyering <jim@meyering.net>
10385 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10386 Fix typo introduced with 2006-04-02 change. It reversed the sense
10389 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10391 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10392 ac_dB slightly, to save bytes in the script.
10393 Max out at 50 lines, rather than 96; this is more likely
10394 (though not guaranteed) to avoid obscure 'sed' failures.
10396 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10398 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10399 `tr -d -' as bad option argument. Work around this by deleting
10400 an unrelated character.
10401 Report by Tim Rice <tim@multitalents.net>.
10403 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10404 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10405 Stepan Kasal <kasal@ucw.cz>
10407 * doc/autoconf.texi (Particular Programs): Do not promise that
10408 we always prefer the GNU version of the program, and that we
10409 search according to PATH; both rules can have exceptions.
10410 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10411 AC_PROG_SED. Move descriptions of limitations
10412 to the Limitations of Usual Tools section.
10413 (Limitations of Usual Tools) <sed>: Mention script length
10414 limitations with Solaris /usr/ucb/sed.
10415 <grep>: Fix wording for empty alternative. Mention that -c and
10416 -l should not be combined, and that -E and -F should not be
10419 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10420 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10422 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10423 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10425 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10427 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10428 AC_DEFINE is now passed to m4_pattern_allow.
10429 * NEWS: Mention that; likewise for AC_SUBST.
10430 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10431 the parameter to m4_pattern_allow.
10432 * tests/tools.at: Add a check for that.
10434 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10436 * lib/autoconf/status.m4: Fix typos.
10438 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10440 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10441 only the files that this macro generates.
10443 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10445 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10446 the HP-UX sed limitation of 99 commands, labels do not count.
10447 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10449 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10451 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10453 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10454 Import the following fix from coreutils:
10456 2006-01-13 Jim Meyering <jim@meyering.net>
10458 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10459 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10460 not double-quote uses of that variable, to accommodate the rare
10461 case in which getmntent is available in none of the libraries
10462 checked. This happens at least on FreeBSD 5.0.
10464 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10466 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10467 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10468 some other programs unwisely rely on these undocumented vars.
10469 But put in warning comments about them.
10470 Problem reported by Ralf Wildenhues in
10471 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10472 * NEWS: Document that these variables are intended to go away.
10474 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10476 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10477 and set the language to C++ (analogous to the equivalent Fortran
10480 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10481 * doc/autoconf.texi (C++ Compiler): Document it.
10482 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10485 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10487 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10488 that caused config.status to generate 100-command sed scripts; the
10489 portable limit is 99.
10491 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10493 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10494 variable `ac_d' instead of `d' to avoid infringing namespace.
10495 Report by Ralf Menzel.
10497 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10499 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10500 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10501 * tests/tools.at (autoconf: subdirectories): New test, taken from
10502 the corresponding problem report by Ralf Wildenhues in:
10503 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10505 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10506 Quote some uses of shell variables if they might suffer unexpected
10507 globbing. This doesn't fix all instances of quoting problems that
10508 I found, just the easy ones that look safe.
10509 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10510 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10511 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10512 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10513 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10514 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10515 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10517 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10518 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10520 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10522 * bin/autoreconf.in ($help): Reword according to the manual.
10523 Suggested by Olly Betts.
10525 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10526 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10528 * bin/autoreconf.in: Pass the directory argument to
10529 `require_configure_ac'. Fix comment.
10530 * tests/torture.at (Configuring subdirectories): Expose this.
10531 Reported by Olly Betts.
10533 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10535 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10536 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10537 Automake as follows:
10539 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10540 `$configure_in' instead of `configure.in', to preserve
10541 directory component.
10543 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10545 * config/config.guess, config/config.sub, config/texinfo.tex,
10546 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10548 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10550 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10551 test for C99 conformance; (bool) 0.5 is an integer constant
10552 expression, but (bool) -0.5 is not. Problem reported by Fedor
10553 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10555 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10557 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10558 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10559 Warn about obsolete install-sh files. Remove stray sentence
10560 fragment and fix cross reference.
10561 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10562 install -d; this undoes the 2006-05-10 change.
10563 (MKDIR_P): Mark with AN_MAKEVAR.
10564 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10565 that we don't require $INSTALL to be thread-safe. Move comments
10566 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10567 of AC_PROG_INSTALL. Output a message saying that we're checking
10568 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10569 MKDIR_P instead of AC_SUBST.
10570 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10571 Special magic for MKDIR_P, too.
10572 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10574 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10576 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10578 Sync from Automake, as follows:
10580 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10581 * config/install-sh: Initialize IFS, so field splitting isn't
10583 * config/mkinstalldirs: Likewise.
10584 * config/missing: Remove superfluous quotes. Replace all uses of
10585 `[' by `test', for consistency, and for..
10586 * config/missing (sed_minuso, sed_output): New variables.
10587 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10588 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10589 Fixes `missing' to detect `--output' for help2man. Fixes
10590 PR automake/483. Report by Dennis J. Linse.
10591 (autom4te): Document in `missing --help'.
10593 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10595 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10596 * config/install-sh: Don't use 'path' to talk about file names,
10597 as per GNU coding standards. Close a race condition reported by Ralf
10598 Wildenhues and Stepan Kasal. There is still a race condition
10599 on hosts that predate Posix 1003.1-1992, but we can't help this.
10600 Don't mishandle weird characters like space on pre-Posix hosts.
10601 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10602 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10603 AC_PROG_MKDIR_P from AS_MKDIR_P.
10604 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10605 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10606 earlier editions are not (including Automake 1.8.3).
10607 Do not suggest mkinstalldirs for thread-safety.
10608 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10609 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10610 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10611 presence of special characters and race conditions.
10612 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10613 in Autoconf's name space.
10615 2006-05-10 Bruno Haible <bruno@clisp.org>
10616 and Paul Eggert <eggert@cs.ucla.edu>
10618 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10619 from Automake with minor changes.
10620 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10622 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10624 * config/install-sh: Update to Automake CVS version, as follows:
10625 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10626 * lib/install-sh: Simplify the expr implementation of dirname.
10627 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10628 * lib/install-sh: Handle --, and diagnose unknown options.
10630 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10632 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10633 `./autom4te' to create `./testsuite', since the `all' target
10634 will ensure its presence, but `installcheck' should not create
10635 the uninstalled wrappers.
10637 * tests/torture.at (Unusual Automake input files): Skip if we
10638 detect automake < 1.8.
10640 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10642 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10643 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10644 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10647 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10649 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10650 munge (multiple) white space and other oddities.
10651 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10652 single quotes in variable assignment.
10653 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10654 and similar failures by adding multiple spaces, tabs, and other
10655 special characters.
10656 Report and different test suggested by Francesco Romani
10657 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10659 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10660 single quotes, we only need to search for single quotes; this
10661 both simplifies the search pattern, and makes us less
10662 susceptible to `echo' variations for arguments not containing
10664 (_AC_ARG_VAR_VALIDATE): Likewise.
10666 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10668 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10669 `$*' and IFS concatenation issue with traditional shells and
10670 bash-2.04. Report by Seanster@Seanster.com.
10672 2006-05-03 Bruno Haible <bruno@clisp.org>

10692 traditional shells like the Solaris one that do not use the
10693 first IFS character for assembling `$*'.
10694 Prompted by a related report from autoconf_bug@nro.ca.
10696 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>

10752 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10754 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10755 since as_me isn't set yet.
10757 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10759 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10760 a few minor bugs in this area.
10762 * doc/autoconf.texi (Programming in M4sh): Comment out the
10763 documentation of AS_BASENAME, for now.
10764 (Shell Substitutions): Do not use AS_DIRNAME in an example.
10765 (Limitations of Builtins) <basename>: Do not refer to
10767 * bin/autoconf.as (me): Don't use AS_BASENAME.
10768 (dir): Remove the unused variable.
10769 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10770 AS_DETECT_REQUIRED. All uses changed.

10789 * lib/autoconf/general.m4: Likewise.
10790 * lib/autoconf/headers.m4: Likewise.
10792 * doc/autoconf.texi (Run Time): Document the exit status situation
10793 with more accuracy and detail.
10795 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10797 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10798 Archive is not officially `GNU' any more. Update URL.
10799 (Defining Directories): Likewise
10800 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10802 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10804 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10805 newline from the `trap' code to finish `config.log'; the NetBSD
10806 /bin/sh resets the exit status after an empty command, as
10807 documented in doc/autoconf.texi.
10808 Reported by Dalibor Topic <robilad@kaffe.org>.
10810 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10812 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10813 Suggested by Bruno Haible.
10815 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10817 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10818 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10819 Instead, just list the shells that we know work.
10820 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10821 changed. Be more cautious about the _cv_ variable.
10822 * tests/tools.at (Syntax of the shell scripts): Check the
10823 _cv_ variable once, at first, to avoid an internal autoconf error
10824 when sh -n does not work.
10826 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10828 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10830 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10832 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10833 use ">&-" since we're only 99.999% sure that this is portable,
10834 and since the MinGW bug is fixed in a different way.
10835 * lib/autotest/general.m4 (AT_INIT): Likewise.
10837 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10839 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10840 before opening config.log, to avoid hitting a bug on MinGW.
10842 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10844 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10845 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10846 This works around a MinGW bug reported by Eric Paire.
10847 Make sure that all writes to the log file append to it,
10848 rather than possibly losing data.
10849 * lib/autotest/general.m4 (AT_INIT): Likewise.
10851 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10853 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10856 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10860 * configure.ac (AC_INIT): Bump to 2.59d.
10862 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10866 * Makefile.maint (news-date-check): Do not require a leading `*'
10867 before the release date in NEWS.
10869 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10870 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10872 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10873 the instantiated file do not contain the string 'datarootdir'
10874 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10875 @mandir@, replace the reference '${datarootdir}' by the value.
10876 * tests/torture.at (datarootdir workaround): New test.
10877 * NEWS: Advertise this temporary fixup.
10878 Based on a patch by Bruno Haible, reported and analyzed by
10879 Paul Eggert and Noah Misch.
10881 2006-04-12 Eric Blake <ebb9@byu.net>
10883 * tests/autotest.at (Debugging a failed test): Fix comment.
10885 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10887 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10888 all the changes since 2006-04-07.
10890 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10892 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10893 succeeded, but `ln -s file dir' failed, take care to remove the
10894 leftover target before the next test, to prevent its spurious
10895 failure; also make sure `ln file dir' works before selecting it.
10896 Thanks to Keith Marshall for pointing this out.
10899 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10900 assignments in `at_debug_args', so that we put them correctly
10901 in the `run' script.
10902 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10903 Reported by Eric Blake.
10905 2006-04-11 Eric Blake <ebb9@byu.net>
10907 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10908 top-level tests after micro-suite has been run. Used in...
10909 (Debugging a successful test, Debugging script and environment),
10910 (Debugging a failed test): ...these new tests. The first of these
10912 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10913 macro, split out from...
10914 (AT_INIT): ...here, so that using -d also generates a run script.
10915 Document that -d inhibits top-level logging.
10916 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10917 inhibits top-level logging; debug scripts are created.
10919 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10921 * tests/autotest.at (Empty test, Empty check): New test to check it.
10923 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10926 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10928 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10929 the files if a problem appears. Make the empty *.at files
10930 read-only, too. Proposed by Ralf Wildenhues.
10932 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10934 * config/Makefile.am: Add comment to force updated Makefile.in.
10936 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10937 space only patch to this file, this patch causes the Makefile.in
10938 files that include freeze.mk to be updated, and thus have a
10939 newer time stamp again, which in turn makes a pristine CVS
10940 checkout have correct time stamps.
10942 * Makefile.maint (cvs-sv): New macro, to be used..
10943 (config.guess-url_prefix, config.sub-url_prefix)
10944 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10945 point to CVS text checkout of Gnulib files.
10946 (copyright-check): Bump current year.
10947 (announcement): Do not hard-wire `./announce-gen'.
10948 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10950 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10952 (wget_files): Update config.guess, config.sub, texinfo.tex by
10953 `wget-update', now that their URLs work again.
10955 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10957 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10958 Problem noted by Paul D. Smith.
10960 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10962 * doc/autoconf.texi: Remove unused words from word list.
10963 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10964 .x-sc_trailing_space: New files.
10966 * doc/standards.texi: Sync from gnulib.
10968 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10969 `LIBOBJDIR' as experimental.
10971 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10972 with a target directory; it's internally implemented as `cp'
10973 anyway, but since Autoconf advertises the possibility to use
10974 a target directory when LN_S is `ln -s', we need to find out.
10975 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10976 analyzed by Keith Marshall <keith.marshall@total.com>.
10980 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10982 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10983 confdefs.h as-is. In general, if it has backslash-newline or the
10984 like, then it doesn't work either to sort or to remove empty
10987 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10989 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10991 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10993 * lib/autom4te.in (Automake-preselections): Preselect
10996 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10998 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10999 apostrophe within a single-quoted string, as this is the usual
11000 tradition and is easier to read than '"'"'. Don't rely on the
11001 shell treating "$/" like '$/'. Use a more-consistent indenting
11002 style for the trap.
11004 2006-04-09 Eric Blake <ebb9@byu.net>
11006 * tests/autotest.at (Backquote command substitution),
11007 (Multiline backquote command substitution): Remove mistaken
11008 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11010 (Parenthetical command substitution, Multiline parenthetical
11011 command substitution): here.
11013 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11015 Import macros from gnulib (often changing their name).

11031 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
11033 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

11037 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
11038 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

11043 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11044 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11045 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11046 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11047 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11048 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11049 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11050 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11051 (Coding Style). Don't mention m4_expand_once.
11052 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

11059 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
11060 (AC_HEADER_ASSERT): New macro.
11061 (AC_HEADER_STDBOOL): Don't assume "#error" works.
11062 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
11063 Catch a bug in an HP-UX C compiler.
11064 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

11072 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11073 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11075 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11077 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11078 of the warning introduced by the 2001-08-28 change.
11080 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11081 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11083 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11084 variables shall be overriden by the cache.
11085 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11086 that contains braces.
11088 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11090 Revert the patch from 2006-04-01 and only improve
11091 _AS_DETECT_BETTER_SHELL:
11093 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11094 skip nonexistent directories.
11095 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11096 only shell candidates which exist.
11097 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11098 * lib/autotest/general.m4 (AT_INIT): No need to give three

11110 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11112 Revert my change from 2006-03-17, in other words:
11113 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11115 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11116 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that

11146 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11147 whether `set' quotes correctly: redirect stderr of the tested
11148 `set', and use a subshell, for Ultrix; use `sed' instead of
11149 `grep' for zsh `set' which may write binary output; match only
11150 at the beginning of a line, to avoid false positives.
11151 In order to avoid false positives by unrelated variables with
11152 multiline content, put the dump algorithm in a subshell and
11153 unset all variables containing newlines (except some which are
11154 special to the shell). Warn about cache variables that are

11160 Sync from upstream.
11162 * tests/mktests.sh: Reword comments.
11164 * tests/mktests.sh: Only skip internal macros starting with
11165 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11166 Update exclusion lists for the test suite to this end:
11167 (AC_ARG_VAR): Do test this now.

11201 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11202 (AC_CONFIG_COMMANDS): Do not do so here.
11203 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11204 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
11205 2005-07-25 rewrite. Noticed by Noah Misch.
11207 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

11259 normalizing it, consistent it with previous releases.
11260 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.

11270 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11271 Use 'comm' rather than N instances of grep; this also fixes a bug
11272 whereby substrings were incorrectly matched, causing us to not
11273 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
11274 (exclude_list): Exclude empty macros.

11362 initial `rm' of the candidate files...
11363 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11364 the same list in subsequent `rm' calls, and for the temporary
11365 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11366 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11367 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11368 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11369 no longer needed) by libtool. Make it a cache check.
11370 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11371 copied here by mistake.

12030 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
12032 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced

12066 CONFIG_SHELL in the environment of the configure rerun.
12067 * doc/autoconf.texi (Here-Documents, config.status Invocation):
12068 Suggest passing CONFIG_SHELL absolute, and in the environment
12069 rather than as option.

12073 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

12089 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
12090 Factor functionality to..
12091 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
12092 `AC_SUBST($1)' in the public version.
12093 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
12094 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
12097 2005-11-01 Stepan Kasal <kasal@ucw.cz>
12099 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3

12114 conftst2.$ac_objext.
12115 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12117 2005-10-24 Stepan Kasal <kasal@ucw.cz>
12119 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
12120 conftest.o, to see whether the compiler really obeys; rm the object
12121 file before and after the test and register it with ac_clean_files.
12122 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12124 2005-10-21 Stepan Kasal <kasal@ucw.cz>
12126 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
12127 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the

12142 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
12144 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
12145 AC_LANG_PROGRAM, fixing a typo. Don't give details about
12146 the inner workings of AC_LANG_FUNC_LINK_TRY.
12147 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12148 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12149 by the function rather than ignoring it.
12150 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12151 comparing its address. Intel's interprocedural optimization was
12152 outsmarting the old heuristic. Problem reported by
12155 2005-10-19 Stepan Kasal <kasal@ucw.cz>
12157 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

12164 2005-10-04 Stepan Kasal <kasal@ucw.cz>
12166 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
12167 before removing it (chmod -R u+rwx); there are three instances of this.
12169 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12170 Stepan Kasal <kasal@ucw.cz>
12172 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12173 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12174 make its content writable before removing it. Remove an errorneous
12175 comment from the end, where the logs of the failed tests are copied
12176 to the main log file.
12178 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12180 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12181 in case the computer is too quick. Double quote the configure.ac
12184 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12185 problems if the testsuite were running too fast.
12187 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12189 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12190 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12191 (which belong to Xt, not X itself). See Debian bug 327655.
12192 * NEWS: Mention this.
12194 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12196 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12198 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12200 * config/move-if-change: Don't output "$2 is unchanged";
12201 suggested by Ben Elliston. Handle weird characters correctly.
12203 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12205 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12206 calls, so that the final expansion of this macro is shorter.
12207 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12208 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12209 the cleanup there. Use AS_VAR_* macros, to be more general.
12210 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12212 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12214 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12216 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12218 * doc/autoconf.texi (Configuration Headers): Add an index entry
12221 2005-08-26 Pavel Roskin <proski@gnu.org>
12223 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable

12227 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12229 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12230 The previous patch didn't work, so try a better one.
12232 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12234 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12235 in the example. Reported by Bruno Haible.
12236 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12237 "if $undefined_var;" succeeds with my shell.
12239 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12240 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12241 but change the m4_divert_text to m4_divert_once.
12243 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12245 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12246 Work around bug in Solaris /usr/xpg4/bin/awk.
12247 The bug is present in at least Solaris 8 through 10.
12249 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12251 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12252 some evil values and relying on the fact that $* concatenates the
12253 parameters by the first character from IFS.
12255 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12256 Stepan Kasal <kasal@ucw.cz>
12258 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12259 first header appears, define AH_HEADER.
12260 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12261 Update limitations about when to call AC_CONFIG_HEADERS.
12262 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12263 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12264 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12265 ``Configuration Actions''; fix their index entries.
12267 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12268 options correctly. Process N-M as M-N if M is smaller than N.
12269 Process ranges correctly so that N-N will run only N.
12270 Sort and uniquify the tests that will be run. If there is more
12271 than one test, reinsert the banners for the tests.
12272 * tests/autotest.at (Keywords): Unmark XFAIL.
12274 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12276 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12277 before passing the macro name to AH_TEMPLATE.
12279 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12280 now opens log after option processing; in particular, --version
12281 and --help do not touch config.log.
12283 * Makefile.maint: Revert the change from 2005-08-12.
12285 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12287 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
12289 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

12293 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
12294 (Autotest Logs, Writing testsuite.at, testsuite Invocation):

12298 Prepend to LIBS, not append, in examples.
12300 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12302 When building in place, set srcdir="."; suggested by Tim Van Holder.
12304 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12305 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12306 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12307 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12308 does not mean "no --srcdir option".
12310 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12312 * tests/autoscan.at (autoscan): New file.
12313 * tests/suite.at: Use it.
12314 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12315 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12317 * tests/autotest.at (Keywords): Test keywords combinations.
12319 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12321 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12322 add "2>&1"; gzip 1.2.4 prints help on stderr.
12324 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12326 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12327 was pushdef'ed twice while popped only once. Push it only once.
12328 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12330 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12332 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
12333 prefixed by mere "===", not "configure: === ".
12335 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12337 * Makefile.maint: Update from Bison.
12339 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12340 "<tab>" in comment, so that the point is understandable.
12342 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12344 Rewrite substantial part of lib/autoconf/status.m4.
12345 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12346 and CONFIG_COMMANDS are not processed in four separate loops.
12347 Instead, there is one main loop. This alows that the common code
12348 is expanded only once, thus config.status (and configure) is smaller.
12350 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12351 the AC_LIST_FILES and cousins macros are no longer used.
12353 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12354 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12355 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12356 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12357 contain the initialization, nor the for loop, nor the associated
12358 commands; all these go to ...
12359 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12360 _AC_OUTPUT_CONFIG_STATUS.
12361 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12362 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12363 (_AC_OUTPUT_FILE): The creation of the sed script ...
12364 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12365 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12366 _AC_OUTPUT_MAIN_LOOP.
12367 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12368 _AC_CONFIG_COMMANDS): Use ...
12369 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12370 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12371 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12372 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12373 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12374 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12376 (_AC_CONFIG_UNIQUE): Update.
12377 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12378 Replaced by this ...
12379 (_AC_LIST_TAGS): ... new common macro.
12380 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12381 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12382 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12383 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12384 this didn't belong to the `config commands' section.
12385 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12386 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12387 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12388 to the `config commands' section either.
12389 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12390 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12392 ... and many changes to the comments nearby.
12394 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12395 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12396 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12397 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12398 (#define header templates): The comment at the top of the generated
12399 header now includes the name(s) of the source file(s).
12401 Several unrelated small changes:
12403 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12404 parameter to AC_DIAGNOSE.
12405 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12406 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12407 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12408 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12409 with AU::AC_OUTPUT.
12410 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12411 in AC_OUTPUT doesn't double-quote it either.
12412 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12415 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12417 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12418 versions of Portland Group compiler produce single- and double-quoted
12419 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12420 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12422 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12424 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12425 This is a corrected version of yesterday's patch.
12427 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12429 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12430 path, too; insert a "===" to emphasize the line.
12432 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12433 ac_cv_build_alias to ac_build_alias.
12434 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12436 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12437 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12438 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12439 (AC_ARG_VAR): ... here.
12440 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12443 Keep a list of all precious variables and process them with one simple
12444 for loop, instead of expanding all commands, or, OTOH, complicated
12445 processing of output of "set".
12446 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12447 variable names in new macro...
12448 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12449 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12450 a loop to assign all ac_env_* and ac_cv_env_* variables.
12451 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12453 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12454 its value to shell variable ac_precious_vars and call
12455 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12456 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12457 _AC_ARG_VAR_VALIDATE.
12459 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12460 and the AC_SUBSTs ...

12478 They are generated by the Tru64 v5.1B shell.
12480 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12482 Fix my changes from 2005-07-01; reported by Noah Misch.
12483 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12484 description, the macro now accepts only a single tag.
12485 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12487 Fix cases when the varsions of Autoconf and Autotest don't match.
12488 Reported by Noah Misch.
12489 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12490 at_top_builddir, for compatibility with older autotest.
12491 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12492 is not set, use at_top_builddir, for compatibility with older
12493 versions of autoconf.

12497 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12498 Problem reported by Patrick Welche.
12500 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12502 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12503 sed substitution command, so that we allow | in program prefixes
12504 and program suffixes. (& is a problem anyway; we're not fixing

12507 configure_input, top_builddir, srcdir, etc.
12508 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12509 PATH_SEPARATOR in AUTOTEST_PATH.
12511 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12513 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12514 for loop over config.site files using `set', to allow
12515 directory names containing IFS characters.
12517 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12519 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12520 directories with weird names. Apparently some people like living

12522 report a name for the working directory.
12523 * NEWS: Remove the claim that we test for funny chars in dir names.
12525 2005-07-01 Stepan Kasal <kasal@ucw.cz>

12539 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12541 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12542 document to output the default config_* lists to config.status.
12543 Don't recognize option --file, if the functionality is not there.
12544 Likewise for --header; moreover, recognize --he and --h as shortcuts
12545 for --help in that case.
12547 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12548 matches the order of execution. No code changed.
12550 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12552 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
12553 single-quoted -cmdline argument in Portland Group compiler.

12567 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12569 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12570 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12571 (AC_SUBST): Call it.
12572 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12573 the directory specific variables; but don't call it for configure_input.
12575 2005-06-28 Derek Price <derek@ximbiot.com>
12577 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12580 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12582 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12583 directory have inherent problems with special characters like spaces,
12584 due to limitations in Make syntax. Problem reported by Alexandre
12586 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12587 Also, fix Tru64 porting problem with shell patterns,
12588 reported by Ralf Wildenhues.

12598 Fix some more shell quoting problems. Prompted by a bug report
12599 from Justace Clutter.
12600 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12601 variable into diagnostic. Make the diagnostic an error, not a warning,
12602 because we really don't support spaces and suchlike in dir names.
12603 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12604 Don't worry about backslashes in srcdir; it can't happen now.
12605 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
12606 Simplify ac_optarg handling.
12607 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

12614 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
12615 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12617 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12618 that '\|' is not allowed in BREs; recommend using newline separated
12619 list of patterns instead of multiple -e options.
12621 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
12623 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

12627 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
12629 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12631 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12632 b, t, r, w commands require single space, while : cannot have any.
12633 (Special Shell Variables): Fix sed code this in the example.
12634 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12635 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12637 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12638 expand to the empty list. Don't use two pairs of m4_changequote,
12639 it's not necessary.
12641 2005-06-20 Derek Price <derek@ximbiot.com>
12643 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12645 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12647 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12648 * doc/autoconf.texi:
12649 Don't mention Solaris versions so much, if a
12650 problem is common to all extant versions of Solaris. Say "SunOS
12651 4" instead of "SunOS" for SunOS 4.
12652 (awk): Mention more of the limitations of traditional Awk.
12653 (cat): Don't talk about cat -v.
12655 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12657 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12658 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
12659 but the implementation is entirely different and is designed
12660 to be compatible with glibc strverscmp.
12661 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12663 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

12666 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12667 Use shell builtins rather than 'expr', to work around expr bug.
12669 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12671 * doc/autoconf.texi: "filesystem" -> "file system".
12672 "behaviour" -> "behavior".
12673 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
12674 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12676 * lib/m4sugar/m4sh.m4: Likewise.
12677 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12678 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
12680 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
12681 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12682 to update the man page. That way, we don't have to check in new
12683 man pages every month.
12685 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12686 quotes and backslashes. Patch from Derek Price.

12695 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12696 -u, since it outputs chatter if the input files are the same.
12697 Problem reported by Ralf Menzel.
12699 2005-06-08 Derek Price <derek@ximbiot.com>
12701 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12702 renaming them since they are about to be redefined anyhow.
12704 2005-06-08 Derek Price <derek@ximbiot.com>
12706 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12707 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12708 Move m4_undefine to alphabetical order.
12710 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12712 * README: Recommend GNU M4 1.4.3 or later.
12713 * doc/autoconf.texi (Introduction): Likewise.
12714 Reword to avoid some formatting glitches.
12715 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12716 Clarify explanation of HP compiler bug.
12717 Redo example output tp match current CVS snapshot.
12718 Use @example.org in email addresses when the examples
12719 might get inadvertently cut-and-pasted into user code.
12720 Remove example of autom4te usage that doesn't seem to work now.
12721 Use modern AC_INIT (except when the example is meant to be
12722 shown with Autoconf 2.13).
12723 Update ksh info for Solaris 9 and later.
12725 Modernize description of Automake versions a bit.
12726 Don't claim a future version of Autoconf is near.
12727 * doc/install.texi: Reword to avoid some formatting glitches.
12729 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12731 * doc/autoconf.texi: Add [] to examples, so that the manual
12732 follows its own advice about quoting better.
12733 Reword to avoid some formatting glitches.
12734 * doc/installt.exi: Reword to avoid some formatting glitches.
12736 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12737 Tru64 ksh pattern matching bug. Reported against Libtool by
12738 Albert Chin <libtool@mlists.thewrittenword.com> and
12739 Nicolas Joly <njoly@pasteur.fr>.
12741 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12743 m4_cdr of one-member list was [[]] (one-member list containing an
12744 empty string) instead of [] (an empty list. Callers were skewed to
12745 match this misbehaviour. As a consequence of this:
12746 - m4_foreach([x], [], [foo]) expanded to `foo', while
12747 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12748 This bug has been fixed:
12750 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12751 expand to an empty string; print error msg if called without
12753 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12754 misbehaviour; handle [] and [[]] correctly.
12756 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12758 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12759 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12760 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12762 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12764 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12765 swallow records with more than 99 fields.
12766 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12767 parse the long line.
12769 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12771 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12772 swallow literals longer than 399. Reported by Ralf Wildenhues.
12773 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12774 to workaround this limitation.
12776 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12778 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12779 to gfortran, and make these the first two compiler names
12780 checked (following the general autoconf preference for gcc).
12782 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12784 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12785 (DISTCLEANFILES): Remove $(check_SCRIPTS).

12788 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12790 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12791 expression of unbounded size when processing the --list
12792 option. This runs afoul of a limit of 399 bytes per regular
12793 expression on AIX. Problem reported by Ralf Wildenhues.
12795 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

12798 * doc/autoconf.texi (Particular Headers): Reword example
12799 for multiline stdbool replacement.
12800 (Setting Output Variables): Reword text a bit. Don't
12801 give all the details about |#_!!_#|.
12802 Reword description of line replacement.
12804 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12806 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12807 now contain newlines, and substituted files must be referenced on
12808 a line alone; the sed scripts to substitute them are now very
12810 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12811 commands can be put in a sed script portably.
12812 * doc/autoconf.texi (Setting Output Variables): Document above
12813 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12814 use of multiline substitution.

12820 From Ralf Menzel (trivial change).
12822 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12824 * tests/local.at: Don't attempt to check for negated character
12825 classes in shell scripts. The test was too brittle.
12827 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12829 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12830 * doc/autoconf.texi (Limitations of Builtins): Document this
12833 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12835 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
12836 common code; used in many places in the tree.

12840 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12842 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12843 messages when ac_unique_file is not found.
12844 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12845 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12846 commands, for consistency with AC_MSG_ERROR and such.
12848 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12850 * bin/Makefile.am: Merge the two rules for creating scripts.

12858 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12860 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12861 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12862 (ac_top_builddir): ... this ...
12863 (ac_top_build_prefix): ... to this; the old name is also kept, for
12864 backward compatibility.
12865 (ac_top_builddir_sub): New variable, without the trailing slash,
12867 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12868 * doc/autoconf.texi (Configuration Actions): Rename

12881 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12882 argument to m4_foreach. I guess it was necessary in the past,
12883 but I think it's a no-op now.
12885 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12887 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12888 ``cat <<_ACEOF'' commands to one.
12889 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12890 * lib/autoconf/status.m4: On various places, use expr instead of
12892 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):

12896 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12897 the wrong patterns between ``case'' and ``esac.'' The previous
12898 code had false positives.

12962 abbreviations of --version and --debug.
12964 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
12966 * doc/autoconf.texi (Autoconf Language): Be more precise about
12967 quoting rules. Problems noted by Stepan Kasal.
12968 Also, throughout this document, be more careful about white space.
12969 "blank", "white space", and "space" all have different meanings
12970 and we should be careful to say what we mean.
12972 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

12989 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
12990 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
12991 set by latest automake.
12993 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12995 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
12996 outputs 0 on GNU/Linux these days.
12998 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13000 * doc/autoconf.texi (Autoconf Language): Add more description
13001 about quoting heuristics.
13002 (Limitations of Builtins): Describe "set -" problems.
13004 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13006 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13009 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13010 by AC_DEFINE; it was a mistake.
13011 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13013 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13015 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13017 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13019 * doc/autoconf.texi (External Software): Quadrigraphs are not
13020 processed correctly in AS_HELP_STRING; avoid this in the examples.
13021 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13022 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13023 comment and reduce m4_default([foo], []) to [foo].
13024 (m4_strip): Update the explanation.
13026 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13028 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13029 Remove core.conftest.* too; it's generated by Tru64 5.1.
13030 Problem reported by Jennis Pruett.
13031 * lib/autoconf/functions.m4
13032 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13033 Don't bother to remove core files; AC_RUN_IFELSE should do that
13036 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13038 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

13052 * doc/autoconf.texi (External Software, Package Options): Add
13053 examples showing how to implement --with-* and --enable-* options.
13055 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13057 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13058 as well as configure.in. Problem reported by Gregorio Guidi.
13060 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13062 * doc/autoconf.texi (Particular Functions): Use gnulib's current

13076 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13078 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13080 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13081 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13082 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13083 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13084 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13086 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13088 * NEWS: The configure command now warns you if you attempt to use
13089 a directory whose name contains a special character like space,
13091 * doc/autoconf.texi (Installation Directory Variables): Allow
13092 "," in file names. Do not use \@; it's not a portable regexp.
13093 * bin/Makefile.am (edit): Likewise.
13094 * lib/Makefile.am (edit): Likewise.
13095 * tests/Makefile.am (edit): Likewise.
13096 * tests/semantics.at: Likewise.

13099 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
13100 * doc/autoconf.texi (File System Conventions): Warn about
13101 unportable file names.
13102 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13104 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13105 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13106 ac_pwd, and quote srcdir.
13107 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13109 * doc/autoconf.texi: Fix some systematic formatting problems.
13110 ".)" needs a following @: if not at the end of a sentence, and
13111 similarly for "!)". "etc." should be preceded by a comma.
13112 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13114 2005-03-22 Bruno Haible <bruno@clisp.org>
13116 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13117 argument is often called 'build-aux'.
13119 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13121 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13122 macro AC_TRY_LINK is obsolete.
13123 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13126 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13128 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13129 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13130 from a Common Lisp's `cl'.
13131 (AC_PROG_CXX): Behave according to the documentation: don't
13132 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13133 make the variable CCC precious; use `cl.exe', not `cl'.
13135 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13136 Alexandre Duret-Lutz <adl@gnu.org>
13138 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13139 /dev/null, as "configure" shouldn't read stdin, and this insulates
13140 us from problems (e.g., when testing for "cl"). Also, do this
13141 redirection before invoking "hostname" or "uname", and keep the
13142 original input stream available via...
13143 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13144 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13145 bother with "</dev/null" since it's now done at the top of
13147 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
13148 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

13154 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13156 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13157 newline if neither \c nor -n work, as that would output two
13158 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13160 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13162 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13163 This causes that any required macros inside will get before the if.
13164 * doc/autoconf.texi (autom4te.cache): A typo.
13166 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13168 Undo previous change, except keep the change to
13169 lib/autoconf/programs.m4 that replaced grep with shell
13170 pattern-matching. This is because net-snmp configure reads stdin.
13171 Reported by Noah Misch.
13173 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13175 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13176 from /dev/null, as "configure" shouldn't read stdin, and this
13177 insulates us from problems (e.g., when testing for "cl").
13178 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13179 before invoking "hostname" or "uname".
13180 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13181 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13182 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13183 "</dev/null" since it's now done at the top of 'configure'.
13184 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13185 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13186 Also, replace grep with shell pattern-matching, to save a process.
13188 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13190 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13191 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13192 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13195 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13197 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13198 grep -q isn't portable. Improve grep -s explanation.
13199 Problem reported by Dan Manthey.
13201 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13203 * doc/autoconf.texi (Special Shell Variables): Clarify
13204 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13206 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13208 * doc/autoconf.texi: Use @acronym for DJGPP.
13209 Fix some @code's that should have been @env's, and vice versa.
13210 Sort environment variable names.
13211 Mention that shells no longer inherit IFS.
13212 Don't recommend PATH_SEPARATOR=';' so strongly.
13213 Mention that $RANDOM might expand to the empty string.
13214 "symlink" and "soft link" -> "symbolic link".
13215 Improve mktemp description (reported by Bruno Haible).
13217 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13219 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13220 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13222 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13225 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13227 * NEWS: Mention AT_COPYRIGHT.
13229 * tests/local.at (AT_CMP): Use diff directly on input files rather
13232 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13233 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
13235 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13236 and Paul Eggert <eggert@cs.ucla.edu>
13238 * tests/autotest.at (Empty test suite): New test.
13239 * tests/torture.at (Substitute and define special characters)
13240 (Substitute a 2000-byte string, Define to a 2000-byte string)
13241 (Substitute a newline, Define a newline): New tests.
13243 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13245 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13246 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13247 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

13251 excess test name quoting.
13252 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
13253 CPPFLAGS to `configure' instead of setting it in `configure'.
13255 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
13256 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
13259 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
13260 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
13262 * tests/local.at (AT_CMP): New macro.
13263 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
13264 (AC_SAVE_STATE): Move environment grep...
13265 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
13266 (AT_CONFIG_CMP): New macro.
13267 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
13268 * tests/c.at (Extensions): Do not exit early.

13271 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
13272 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
13274 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
13275 (AC_COPYRIGHT): Factor header comment portion out and move into...

13288 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
13290 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
13291 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
13293 Try not to generated lines of unlimited length, as POSIX places a
13294 2047-byte limit on line length of portable text files.
13295 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
13296 Use newline as a separator, not space.

13304 as_func_*. Add test to check whether positional parameters
13305 are restored after function return.
13307 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
13309 * doc/autoconf.texi (Special Shell Variables): Mention _,
13310 BIN_SH, DUALCASE. Say that variables other than "status" are safe
13311 if they contain a lower-case letter. The DUALCASE problem was
13312 reported by Ralf Wildenhues.
13314 * bin/autoconf.as: Don't exit with status 0 after write failure
13315 with --help or --version.
13316 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

13321 * doc/autoconf.texi (Limitations of Usual Tools):
13322 Unicos 9 sed limitations.
13323 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
13324 to get the option-enhanced interface on older Crays. Try ftn for
13325 Fortran 95 (newer Crays).
13327 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
13329 * man/Makefile.am (.x.1): Go back to the simple solution, but take
13330 care to echo the commands, so the user knows what's going on.
13331 Modified from a suggestion by Stepan Kasal.
13333 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
13334 with a cross reference. Derived from a suggestion by Bruce Korb.

13343 * man/Makefile.am (.x.1): Make sure the required generated files
13344 are up to date. Problem and original solution proposed by Stepan Kasal.
13345 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
13346 implicit-man-prerequisites): New rules, used by the above.

13354 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13355 Update the long comment explaining it.
13357 m4_require no longer writes an ``is required by'' line to the
13358 execution stack. It contains only one bit of non-redundant
13359 information: that the macro was required, not called. And even
13360 this bit is useless in most situations: have you ever met a macro
13361 which both calls and requires the same macro?
13363 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13364 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13367 (m4_expansion_stack_pop): Remove the misplaced comment.
13368 (m4_require): Don't put the ``is required by'' line to the
13369 execution stack; slightly improve the out-of-a-defun error message.
13370 (_m4_divert_grow): New macro, counter for the temporary diversions.
13371 (_m4_require_call): Use it.
13372 * tests/m4sugar.at (m4_require): Expect output without the
13373 ``is required by'' messages.
13375 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
13377 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
13378 rather than x for expr.

13409 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
13411 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.

13468 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
13469 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
13470 stored in _m4_divert_diversion or _m4_divert_dump.
13471 (m4_divert_pop): When the parameter is given, compare the symbolic
13472 name with the last diversion pushed on the stack. Previously, the
13473 current diversion was compared with the numeric value of the
13474 diversion given as the parameter.
13475 (m4_require): If the macro hasn't been expanded yet, call ...

13758 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
13759 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
13760 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
13762 2004-12-07 Stepan Kasal <kasal@ucw.cz>
13764 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

13779 with exactly one parameter.
13781 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
13783 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13784 "char c = '\200';" rather than "char c = 0x80;" as the
13785 latter doesn't conform to the strict C standard due to
13786 overflow on signed char hosts.
13788 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
13789 to -qlanglvl=ansi. We don't want to disable extensions.
13791 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>

13902 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
13903 "/usr/include", clear ac_x_includes instead of leaving it as "no"
13904 (trivial change). Problem and patch reported by Andrew Church in:
13905 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

13937 Remove ansi2knr.c; nobody uses it.
13938 (ansi2knr.c-url_prefix): Remove.
13939 (cvs-update): Fix test for failure. I don't know why it ever
13942 * doc/autoconf.texi: Update URLs, some of which went stale.
13943 Use @uref rather than @href.
13945 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
13946 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
13948 * config/config.guess, config/config.sub, config/elisp-comp,
13949 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

13960 Use "file name" rather than "filename" or "path",
13961 to be consistent with the terminology of the GNU coding standards.
13963 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13965 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13966 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13967 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13968 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13970 More fixes to support spaces in the name of the build directory.
13971 This isn't a complete fix but it's an improvement.
13973 * bin/autoconf.as (autom4te_options): New var.
13974 Use it instead of appending to AUTOM4TE, so that we can allow
13975 spaces in the build directory's absolute name.
13976 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13977 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13978 AT_CHECK_NOESCAPE): Likewise.
13979 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

13990 * doc/autoconf.texi (Function Portability): Document isinf and
13991 and isnan. From a suggestion by Kevin Ryde.
13993 * lib/Autom4te/General.pm (END): Return correct exit status even
13994 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13996 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13998 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13999 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14000 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
14002 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
14004 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
14005 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
14006 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
14007 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
14008 * lib/autom4te.in (Automake-preselections): Preselect
14009 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14011 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14013 * lib/autom4te.in (Automake-preselections): Preselect
14014 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14017 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

14022 Document problem with "`""`" in pdksh POSIX mode.
14024 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14026 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14027 with pdksh, too. Problem reported by Patrick Welche via
14029 * doc/autoconf.texi (Shellology): Note that set -o posix is
14030 useful for pkdsh, too.
14032 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14034 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14035 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14036 Don't fail if ENV or BASH_ENV is readonly.
14037 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14038 etc. are read only. Problem reported by Ludovic Courtes.
14040 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14042 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14043 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14046 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14048 * doc/autoconf.texi (File System Conventions): Warn about
14049 names like "aux". Problem reported by Eric Blake.
14051 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14052 by zero instead of array size, so that we can use any arithmetic
14053 constant expression (instead of requiring an integer constant
14054 expression). This allows us to test expressions like DBL_MAX <
14055 LDBL_MAX, which didn't conform to the C standard using the old
14057 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14058 now that we can do floating-point tests at compile time.
14060 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14062 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14063 and LDBL_EPSILON, as the resulting expression isn't an
14064 integer constant expression and violates the C standard.
14065 Problem reported by Nelson H. F. Beebe. Also, check
14066 for "L" suffix, and check that long double doesn't have
14067 worse range or precision than double, that mixed-mode
14068 arithmetic doesn't generate a diagnostic, that double
14069 constants fit in long double.
14071 2004-06-03 Kevin Ryde <user42@zip.com.au>
14073 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14074 malloc(0) and realloc(NULL,size).
14076 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14079 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14081 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14082 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14085 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14087 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14088 can be rewritten using if-then-else. Suggested by Bruno Haible.
14090 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14092 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14093 Problem reported by Stepan Kasal.
14095 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14097 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14098 change). Patch reported by Ralf Wildenhues in
14099 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14101 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14102 function F exists if the compiler and linker let you compile an
14103 expression like (F != 0). Recent versions of GCC optimize away
14104 the reference to F in that case, since every function address must
14105 be nonzero, so the link succeeds even if F does not exist.
14106 Problem reported by Manu in
14107 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14109 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14110 "Unix". Many uses changed.
14111 (Limitations of Builtins): Explain better why the ! command isn't
14114 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14116 * lib/autom4te.in (Automake-preselections): Preselect
14117 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14119 2004-05-19 Kevin Ryde <user42@zip.com.au>
14121 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14122 referencing AC_FUNC_STRERROR_R.
14124 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14125 note pessimistic assumption when cross compiling.
14127 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14129 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14130 (until 2004) invoked subcommands with sh -e, contra POSIX.
14131 Reported by Kevin Ryde.
14133 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14135 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14136 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14137 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14138 `test -f " /usr/bin/grep"', which _always_ failed.
14139 (AC_PROG_SED): Ditto bogus PATH fix.
14140 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14141 requires that grep correctly supports _multiple_ `-e' options, rather
14142 than stating only that grep should accept `-e'.
14144 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14146 Port to C99, which requires that 'exit' be declared.
14148 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14149 to ensure that stdlib.h is included.
14150 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14151 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14152 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14153 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14154 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14155 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14156 when using 'exit' in a test; C99 requires that 'exit' be declared.
14158 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14160 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14161 now prefers 'grep' implementations that accept -e.
14162 (Limitations of Usual Tools): Describe problems of traditional
14163 egrep and fgrep with long input lines, and of traditional grep
14165 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14166 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14167 All callers changed. Append /usr/xpg4/bin to the PATH, for
14169 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14170 the user with complaints about multiple -e options.
14171 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14172 Define it with AC_PROG_GREP.
14173 * configure.ac (AC_PROG_GREP): Add.
14174 * lib/freeze.mk (GREP): New macro.
14176 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14178 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14179 a possible candidate only after all others fail, rather than
14180 consulting it first. This improves backward compatibility by
14181 better reflecting the way shell selection occurred in previous
14182 versions of Autoconf, and should help to avoid triggering latent
14183 problems in other packages, such as the one in Automake where zsh
14184 is not handled robustly:
14185 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14186 Although it is not Autoconf's responsibility to work around
14187 problems in Automake, it nevertheless makes sense to avoid
14188 introducing unnecessary incompatibilites.
14190 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14191 Gary V. Vaughan <gary@gnu.org>
14193 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14194 how deeply nested we are when a suitable tool is found, set the
14195 ac_path_TOOL_found flag.
14196 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14197 nested we are in this macro. Break out of all 3 nested loops if
14198 ac_path_TOOL_found is set.
14200 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14202 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14203 of the _AS_PATH_WALK loop too if GNU flavor is found.
14205 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14207 * doc/autoconf.texi (Limitations of Make): Update documentation
14208 for `$<'. New entry `Long lines', based on a report from Simon
14209 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14210 paragraph about DJGPP, based on a mail from Richard Dawe.
14212 2004-04-20 Paul Eggert <eggert@twinsun.com>
14214 * tests/c.at (C keywords): Don't assume that GCC supports
14215 "restrict" and "inline", as sufficiently-old GCC versions do not
14216 (also, GCC configured to be in pedantic C89 mode does not).
14217 Problem reported by Sumit Pandya in:
14218 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14220 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14221 consider -g to work if it generates warnings when plain compiles
14222 don't. Problem reported by Braden McDaniel in:
14223 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14225 * doc/autoconf.texi (Slashes): New section, to document a problem
14226 reported by Jim Meyering in:
14227 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14229 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14230 linker output files before linking, to work around IRIX 6 linker bug.
14231 Problem reported by Rainer Orth in:
14232 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14234 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14236 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14237 best tool so far counter rely on the tool path variable name to
14238 avoid checks for one tool being affected by the results of running
14239 the length check on a previous tool.
14241 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14242 match expression argument, as different greps have different

14347 * bin/Makefile.am (edit): Don't use $< in a context where
14348 POSIX doesn't require support for it. Use $@.in instead.
14349 Problem reported by Anthony N. Frasso in
14350 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

14366 Fix a dependencies problem, stemming from a Autoconf 2.59 build
14367 problem on QNX reported by Stephen Rasku in

14370 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
14371 $(m4sh_m4f_dependencies); this removes a FIXME.
14372 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.

14374 one per related section. Add $(srcdir)/wrapper.in.

14379 AC_SUBST provides no portable way to escape literal newlines.
14381 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14382 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14383 Darwin uses -lcrt2.o and there's little point to cataloging all
14384 the system variants. Partial fix reported by Andreas Waechter in:
14385 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

14409 Eric Sunshine <sunshine@sunshineco.com>
14410 Paul Eggert <eggert@twinsun.com>
14412 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14413 (AS_INIT): Output shell initialization there. Removed optional
14414 parameter. Expand _AS_SHELL_FN_SPY.

14427 trigger the bash bug anymore.
14428 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
14429 use AS_INIT_WITH_SHELL_FN.
14430 * bin/autoconf.in, tests/wrapper.in: Regenerated.
14432 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

14439 macros with AU_DEFINE.

14460 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

14462 the 2003-05-22 change, which removed the older years from the list.
14463 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

14474 egrep and fgrep respectively if $GREP -E/-F don't work.
14475 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
14476 _AC_PROG_GREP, and AC_PROG_SED.
14477 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14478 longest input length accepted by a command.

14507 2004-01-26 Paul Eggert <eggert@twinsun.com>
14509 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14510 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14511 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14512 not <inttypes.h>. Problem reported by Tim Mooney in
14513 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14514 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14517 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14518 otherwise "make check" fails because it forbids cmp (I guess
14519 because cmp treats files as binary on DOS-like systems).
14521 * tests/mktests.sh: Update copyright date to 2004, since some tests
14522 have changed in 2004.
14524 2004-01-23 Gary V. Vaughan <gary@gnu.org>
14526 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
14527 non-truncating sed or gsed program in PATH.
14528 * tests/acprograms.at: Add it.
14529 * doc/autoconf.texi (Particular Programs): Document it.
14532 2004-01-15 Paul Eggert <eggert@twinsun.com>
14534 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14535 -std1 disables some useful extensions on Tru64. Problem reported
14536 by N. Lichtmaier in
14537 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14539 2004-01-14 Paul Eggert <eggert@twinsun.com>
14541 * doc/autoconf.texi (Programming in M4sh): Document that
14542 AS_MKDIR_P succeeds if the destination is a symbolic link
14543 to an existing directory.
14544 (Limitations of Usual Tools): Note that mkdir -p might not
14545 succeed on symlinks to directories.
14547 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14549 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14550 * bin/autoheader.in: Grammar fix in message.
14551 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14552 Test for dir before calling mkdir -p. (trivial changes)

14559 2004-01-10 Jim Meyering <jim@meyering.net>
14561 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
14563 2004-01-09 Paul Eggert <eggert@twinsun.com>
14565 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14566 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14567 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14568 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14569 AC_COMPILE_IFELSE, since we now assume our caller invokes
14570 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14571 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14572 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14573 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14575 2004-01-07 Paul Eggert <eggert@twinsun.com>
14577 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14578 `"'...'"`, as it's confusing (and I suspect it may not work on
14579 some platforms). The code was incorrect anyway, as it assumed
14580 that \$ evaluated to itself in that context. Reported by
14581 Alexandre Duret-Lutz.
14583 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14585 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14586 and _LT_AC_TAGCONFIG.
14588 2004-01-06 Paul Eggert <eggert@twinsun.com>
14590 * doc/autoconf.texi (One Macro Call): Fix an incorrect
14591 example, and add more examples. Reported by Eric Sunshine.

14609 by doing lineno substitution only on lines containing "$LINENO".
14611 2004-01-04 Paul Eggert <eggert@twinsun.com>
14613 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14614 Use "rm -f" to remove conftest.sed, not plain "rm".
14615 Bug reported by David Relson in
14616 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14618 * Makefile.am (autom4te-update):
14619 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

14633 2004-01-03 Paul Eggert <eggert@twinsun.com>
14635 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14636 -c -o might not work. From a suggestion by Kevin Ryde.
14637 (C Compiler, Generating Sources, Limitations
14638 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14639 Don't put '-o' after non-options, as POSIX doesn't allow this.
14640 Mention that cc's name might be gcc or c89 or whatever.
14642 2004-01-04 Kevin Ryde <user42@zip.com.au>
14644 * doc/autoconf.texi: Add various further index entries.
14646 2003-12-29 Paul Eggert <eggert@twinsun.com>
14648 * bin/autoreconf.in (autoreconf_current_directory):
14649 Fix typo: mkdir without umask arg.
14651 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14653 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14654 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
14655 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
14656 explanation clearer.
14658 2003-12-24 Andreas Schwab <schwab@suse.de>
14660 * doc/autoconf.texi (Default Includes): Fix misspelling of

14666 * configure: Regenerate.
14667 * tests/atlocal.in: Store the result here.
14668 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
14669 tools.at, looking in atlocal's ac_cv_sh_n_works instead
14670 of explicitly testing.

14967 cache variable instead of $G77 to decide whether to include -O2,

14978 arguments so that it can be used with syntax identical to

14980 remove/deprecate the DIALECT optional argument in the future if it
14981 proves troublesome.
14982 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

15054 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15055 directory for AC_CONFIG_COMMANDS' first argument exists.
15056 This makes valid the invocation of _AC_SRCPATH that follows.
15057 Reported by Eric Sunshine.

15081 The test suite are sometimes assigning timings incorrectly.
15082 Reported by Henk Krus.
15083 Diagnosed by Nicolas Joly.
15085 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15087 Instead of making AT_help a sequence of assignments to grow

15089 $at_help_all, and make a single assignment in...
15091 (at_times_skip): Flip the meaning and rename as...

15105 executables, not bin/ executables! Otherwise all the magic needed
15106 to find non installed files is turned off. This caused a failure
15107 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15108 as found in its environment (sent by tests/autoreconf): pointing
15109 to bin/autom4te that could not find its files.
15110 * tests/mktests.sh: Force the replacement of generated files, for
15111 the sake of "mv" program that are interactive when overwriting a

15340 2003-08-21 Akim Demaille <akim@epita.fr>
15342 First stab at preserving warnings between calls to autom4te,
15343 including when the cache is used.
15345 There are still several issues: (i) there are too many runs of m4
15346 (one for include, one for warnings, and some more), (ii) warnings
15347 spreading on several lines are not handled gracefully, (iii) the
15348 code meant to have the call stack display for errors does not work
15349 (its handling should move from m4 to autom4te).
15351 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15353 (@preselect): Add m4_warn.
15354 ($exit_status): Remove, use $exit_code.
15355 ($help): Use Autom4te::ChannelDefs::usage.
15356 (&handle_m4): No longer define the m4_warnings.
15357 At each run, extract and report the warnings.
15358 Always cache the result, including if the exit status is on
15359 failure, since if nothing changes, we should result in the same
15360 failure, hence we can use the cache.
15361 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15362 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15364 (m4_warn): Redefine as a do-nothing: it is its invocation that
15365 matters, as warnings are now reported via traces.
15366 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15367 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15368 the latter reveals calls to the former.
15372 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

15394 (&catfile): Remove.
15395 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,

15401 Reported by Alexandre Duret-Lutz.

15405 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15406 * bin/autom4te: Adjust.
15407 In particular, be Autoconf tools are really silent when properly
15408 working, bind the verbosity of the 'note' channel to $verbose.
15409 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

15537 Don't mix the detailed output of failed test with the summary of

15650 * Makefile.am, bin/Makefile.am, config/Makefile.am,
15651 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:

15655 Paul Eggert <eggert@twinsun.com>
15657 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15658 Remove `#include <stdlib.h>' from the list; we should never
15659 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15660 resulting namespace pollution would cause other tests to fail.
15661 Configure scripts run with some older versions of g++ and HP's
15662 aCC would fail due to such an #include. Problems reported by
15663 Matthew Mueller in <http://bugs.debian.org/120704> and by
15665 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15666 In the test, use the test declaration before including <stdlib.h>,
15667 as that's closer to how it'll be used.
15669 2003-05-23 Akim Demaille <akim@epita.fr>
15671 * doc/autoconf.texi (Header Portability): ucred.h.
15674 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15676 Overhaul Autotest's logging: generate separate log files
15677 in testsuite.dir/NNN/testsuite.log, and append them to
15678 testsuite.log instead of re-running the test verbosely.
15680 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15681 file descriptor, write 0 to at_status_file instead of setting
15682 at_status=0, initialize some new variables (at_status_file,
15683 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15684 to rerun the tests, instead append the at_group_log to the
15685 at_suite_log when a test fails.
15686 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15687 with the AS_MESSAGE_LOG_FD redirected to stdout.
15688 (AT_CLEANUP): save the output status in $at_status_file
15689 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15690 its original place.
15691 (AT_CHECK): since tests are run with a redirected stdout,
15692 and used to be re-run in verbose mode, turn some $at_verbose
15693 into echo, and don't redirect the output of testing stdout
15696 * lib/autotest/autoconf.texi (testsuite Scripts): Update
15697 the name of the debugging directory and information about

15817 2003-05-06 Akim Demaille <akim@epita.fr>
15819 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15820 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15821 by aclocal.m4 is changed it might require the importing of another
15822 m4 extension file, i.e., aclocal must be run.
15824 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15825 (&parse_args): Use --force with aclocal if required and supported.

15839 2003-04-29 Derek Price <derek@ximbiot.com>
15841 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15842 seperator with m4_append_uniq(). It doesn't work.
15843 (AT_CLEANUP): Add `;' to end of at_help_all.
15844 (AT_INIT): Allow --keywords to be specified more than once. When
15845 grepping $at_help_all for keywords, use the field and keyword
15846 seperators to ensure a complete keyword match. Alter at_prev handling
15847 to support the new --keywords behavior.
15849 2003-04-27 Karl Berry <karl@freefriends.org>
15851 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15852 align better with others. I also made some of the individual
15853 entries on one line, for brevity and to make it easier for me to
15854 sort my dir-example file in the Texinfo distribution :).

15925 * tests/torture.at (Configuring subdirectories): Require aclocal
15926 1.4, otherwise the test fails, as it does support configure.ac.

16074 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16075 innocuous variant befor including <limits.h> or <assert.h>. This

16077 (and earlier versions) have a <limits.h> that declares
16078 gettimeofday and many other functions.
16080 2002-12-03 Paul Eggert <eggert@twinsun.com>

16094 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16095 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16096 defined, to support freestanding compilers. This should fix the
16097 bug reported by Momchil Velkov in
16098 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16100 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16101 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16136 * Makefile.maint: Sync with Bison, i.e.:
16137 (po-check): Scan .l and .y files instead of the
16138 .c and the .h files that they generate. This fixes the bug
16139 reported by Tim Van Holder in:
16140 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16141 Look for N_ as well as for _. Try to avoid matching #define for
16145 2002-11-14 Akim Demaille <akim@epita.fr>

16155 2002-11-14 Kevin Ryde <user42@zip.com.au>
16157 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16158 than assigning in main, to avoid HP cc +O3 optimizing it away.
16160 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16162 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16163 option. Process --recheck after parsing all options. Pass -q
16164 option to configure on --recheck.
16165 (AC_OUTPUT): Pass -q from configure to config.status.
16166 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16167 arguments to record.
16168 * doc/autoconf.texi (config.status Invocation): Document
16169 config.status -q option.
16171 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

16196 Reported by Ezra Peisach.
16198 2002-11-05 Akim Demaille <akim@epita.fr>
16200 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16202 We _have_ to stop using the old compatibility scheme that tried to
16203 avoid useless backslashes because Libtool 1.4.3 contains a
16204 AC_DEFINE([error_t], [int],
16205 [Define to a type to use for \`error_t' if it is not
16206 otherwise available.])
16207 We _have_ to quote the single quote and backslashes with \. The
16208 old compatibility scheme saw that ` was backslashed, and therefore
16209 did not quote the single quote. Hence before this patch, Autoconf
16210 was not compatible with Libtool.

16234 * doc/autoconf.texi (autoreconf Invocation): Adjust.

16256 Make variable, not a shell variable.
16257 Suggested by Bruno Haible.

16283 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
16284 Problem reported by Bruno Haible.

16601 Reported by Alexandre Duret-Lutz.
16603 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16631 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
16633 2002-10-11 Akim Demaille <akim@epita.fr>
16635 No longer use CPP to check for the existing of headers: use CC to
16636 check for compilability.
16638 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
16639 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
16640 (_AC_CHECK_HEADER_NEW): Rename as...
16641 (AC_CHECK_HEADER): this.
16643 * lib/autotest/general.m4 (AT_INIT): Include the failed test
16644 numbers in the Subject suggestion.
16646 2002-10-11 Akim Demaille <akim@epita.fr>
16648 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
16649 Suggest using AC_CHECK_DECLS instead.
16651 2002-10-11 Akim Demaille <akim@epita.fr>
16653 * tests/torture.at (AC_ARG_VAR): Have configure report the value
16656 2002-10-11 Akim Demaille <akim@epita.fr>
16658 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
16659 file name to enable parallel executions.
16660 From Sam Varshavchik.
16662 2002-10-08 Akim Demaille <akim@epita.fr>
16664 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16665 aclocal invocation, as Gettext macros might not be visible to
16667 Instead of blindly running autopoint, scan configure.ac (not the
16668 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16669 Reported by Paul D. Smith.
16671 2002-10-08 Paul Eggert <eggert@twinsun.com>
16673 Work around problems found when POSIXLY_CORRECT=1 is set.
16674 None of this seems to have anything to do with POSIX, really,
16675 but it's how Perl getopt works.
16676 * bin/autom4te.in (parse_args): Configure GetOpt with
16678 * doc/autoconf.texi (Invoking autom4te):
16679 --warning -> --warnings.
16680 * lib/autom4te.in: --warning -> --warnings.
16682 2002-09-28 Akim Demaille <akim@epita.fr>
16684 * doc/autoconf.texi (autom4te.cache): New section.
16686 2002-09-28 Akim Demaille <akim@epita.fr>
16688 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
16689 (Automake-preselections): Update.

16692 2002-09-28 Akim Demaille <akim@epita.fr>
16694 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
16695 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
16696 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16697 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
16699 2002-09-28 Akim Demaille <akim@epita.fr>
16701 * tests/torture.at (Configuring subdirectories): Be robust to
16702 users who use config.site to require for a cache: in this case,
16703 the two last configure runs, using two different sets of
16704 arguments, trigger a legitimate error.
16706 2002-09-28 Akim Demaille <akim@epita.fr>
16708 * tests/m4sh.at (Functions Support, Functions and return Support):
16711 2002-09-28 Akim Demaille <akim@epita.fr>
16713 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
16714 autoheader are Perl programs.
16715 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
16716 (autom4te): Specify that the sources are in the $srcdir.

16724 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
16725 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
16726 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
16727 * lib/autoconf/programs.m4: here.

16737 that were listed in the original autoscan.list.
16738 * lib/autoconf/headers.m4: Similarly with headers.
16739 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
16740 (.m4.m4f): Don't pass --prepend-include, since that's done by
16741 tests/autom4te itself.
16742 * lib/autoscan/Makefile.am: Include freeze.mk.
16743 (autoscan.list): New target --this file is no longer a source.
16744 (autoscan.pre): New file.
16746 2002-09-28 Akim Demaille <akim@epita.fr>
16748 * bin/autoscan.in (@kinds): Make them singular.
16750 (&init_tables): When --debug, report the list of rules to ease
16751 tracking changes in autoscan.list.
16752 * lib/autoscan/autoscan.list (function): Strip comments, sort.
16754 2002-09-28 Akim Demaille <akim@epita.fr>
16756 * lib/autoscan/functions, lib/autoscan/headers,
16757 * lib/autoscan/identifiers, lib/autoscan/makevars,
16758 * lib/autoscan/programs: Merge into...
16759 * lib/autoscan/autoscan.list: this.
16760 * bin/autoscan.in (&init_tables): Adjust.
16762 2002-09-28 Akim Demaille <akim@epita.fr>
16764 * lib/autoscan/functions, lib/autoscan/headers,
16765 * lib/autoscan/identifiers, lib/autoscan/makevars,
16766 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
16767 `functions' line is now prefixed with `function:'.
16768 * bin/autoscan.in (&init_tables): Adjust.
16770 2002-09-28 Akim Demaille <akim@epita.fr>
16772 From now on, autoscan files must always map a macro name to a
16773 word: there is no `default' macro for autoscan.
16775 * bin/autoscan.in (&init_tables): Reject entries with no macro at
16777 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
16780 2002-09-28 Akim Demaille <akim@epita.fr>
16782 * bin/autoscan.in (%c_keywords): Remove.
16783 (&used): Keep only track of the words we might be interested in.
16784 (&output_kind): It is no longer needed to look for non active
16787 2002-09-27 Akim Demaille <akim@epita.fr>
16789 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
16790 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
16791 * lib/autoscan/functions: Adjust.
16792 * doc/autoconf.texi (Particular Functions): Adjust.
16794 2002-09-27 Akim Demaille <akim@epita.fr>

16798 Thanks to Bill Moseley and Paul Eggert.
16799 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
16800 the tmpdir must be created.
16801 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
16802 dir be in the build tree, instead of $TMPDIR.
16804 2002-09-27 Akim Demaille <akim@epita.fr>
16806 * bin/autoscan.in: Improve the comments.
16807 (&parse_args): Drop obsolete undocumented options.
16808 (&output_kind): Output warnings.
16809 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

16812 2002-09-26 Akim Demaille <akim@epita.fr>
16814 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
16815 Reported by Ralf Corsepius.
16816 * doc/autoconf.texi (autoreconf Invocation): Likewise.
16818 2002-09-26 Akim Demaille <akim@epita.fr>
16820 Single suffix rules and seperated dependencies are not portable.
16822 * doc/autoconf.texi (Installation Directory Variables): Update.
16823 (Limitations of Make): Some about `Single Suffix Rules and
16824 Separated Dependencies'.
16825 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16826 (ifnames, autoscan, autom4te): Un-factor into several rules.
16828 2002-09-25 Paul Eggert <eggert@twinsun.com>
16830 * BUGS (Interoperability bugs): New section. Mention libtool
16831 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16833 2002-09-24 Paul Eggert <eggert@twinsun.com>
16835 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16836 make handles suffix-rules differently from GNU make.
16838 * bin/Makefile.am (SUFFIXES, .in): Remove.
16839 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16840 Move the body of the old .in rule here.
16842 2002-09-16 Akim Demaille <akim@epita.fr>
16844 i960 compilers create `b.out' files by default.
16845 Reported by Ralf Corsepius.
16847 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16848 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16850 2002-09-13 Paul Eggert <eggert@twinsun.com>
16852 * doc/autoconf.texi (Particular Headers): Remove obsolete
16853 reference to `struct timezone' in the description of
16856 2002-09-13 Akim Demaille <akim@epita.fr>
16860 * config/config.sub, config/config.guess: Update.
16861 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
16862 * Makefile.am: Adjust.
16864 2002-09-13 Akim Demaille <akim@epita.fr>
16866 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16867 reading config.log when the compiler is rejected.
16868 Suggested by Guido Draheim.
16870 2002-09-13 Akim Demaille <akim@epita.fr>
16872 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16873 (chdir_init) might hang when stat'ing mounted directories.
16874 Reported by Vance Shipley.
16876 2002-09-12 Akim Demaille <akim@epita.fr>
16878 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16881 2002-09-12 Akim Demaille <akim@epita.fr>
16883 * doc/autoconf.texi (Defining Symbols): Present two different
16884 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16885 difference between 1 argument calls, and 2-3 argument calls.
16887 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16889 * doc/autoconf.texi: Review grammar and punctuation.
16891 2002-09-11 Paul Eggert <eggert@twinsun.com>
16893 * doc/autoconf.texi: Fix minor formatting, spelling, and
16895 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16896 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16899 2002-09-11 Akim Demaille <akim@epita.fr>
16901 * doc/autoconf.texi (Questions): Rename as...
16903 (Defining Directories): New.
16905 2002-09-09 Akim Demaille <akim@epita.fr>
16907 * doc/autoconf.texi (Making testsuite Scripts): Update.
16908 Suggested by Nishio Futoshi.
16910 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16912 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16913 plain `@' is wanted.
16915 2002-09-09 Akim Demaille <akim@epita.fr>
16917 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16918 `duplicates', since the algorithm was too naive and could keep
16919 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16920 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16921 Reported by Ralf Corsepius.
16922 * tests/torture.at (Configuring subdirectories): Exercise these
16925 2002-09-09 Akim Demaille <akim@epita.fr>
16927 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16928 looking for a replacement file.
16929 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16930 directory is relative.
16931 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16932 directory definition.
16933 Reported by Andreas Schwab and Jim Meyering.
16935 2002-09-06 Akim Demaille <akim@epita.fr>
16937 * doc/autoconf.texi (Setting Output Variables): Clarify what
16938 precious variables are.
16939 Suggested by Pontus Skoeld.
16941 2002-09-05 Akim Demaille <akim@epita.fr>
16943 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16944 (ifnames, autoscan, autom4te): Since we don't only depend on
16945 configure.ac variables (such as VERSION etc.), but also on prefix
16946 and so forth, depend on Makefile, not configure.ac.
16947 Reported by Alexandre Duret-Lutz.
16948 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16950 2002-09-05 Kevin Ryde <user42@zip.com.au>
16952 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16953 doesn't seem to be confined to ia64, just say "some versions".
16955 2002-09-04 Akim Demaille <akim@epita.fr>
16957 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16959 * Makefile.am (maintainer-clean-local): Remove.
16960 (MAINTAINERCLEANFILES): Remove COPYING.
16962 2002-09-03 Paul Eggert <eggert@twinsun.com>
16964 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16965 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16968 2002-09-03 Akim Demaille <akim@epita.fr>
16970 * configure.ac: Bump to 2.53d.
16971 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16972 as of today, on Automake's team suggestion.
16974 2002-09-03 Akim Demaille <akim@epita.fr>
16978 2002-09-02 Akim Demaille <akim@epita.fr>
16980 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16982 * configure.ac: Disable SITE_MACRO_DIR.
16984 2002-09-02 Jim Meyering <meyering@lucent.com>
16986 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16987 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16988 Also, tweak grammar: s/make sure to/be sure to/.
16990 2002-09-02 Paul Eggert <eggert@twinsun.com>
16992 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16993 directory names are generally preferable to physical names.
16995 2002-09-02 Akim Demaille <akim@epita.fr>
16997 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16998 Reported by Raja R. Harinath.
16999 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17000 * bin/autoupdate.in: Use error instead of die.
17002 2002-09-01 Paul Eggert <eggert@twinsun.com>
17004 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17005 ordinary shell concatenation rather than echo+tr+sed command that
17006 runs afoul of a long-line-related sed bug in Solaris 8.
17008 * bin/autoheader.in (parse_args): --warning -> --warnings.
17010 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17011 stdout, as traditional "ls" does.
17012 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17013 _AC_COMPILER_EXEEXT_O): Likewise.
17014 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17016 * bin/autoconf.as: Add --prepend-include option. This patch was
17017 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17018 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17020 * bin/autoconf.in, configure: Regenerate.
17022 * doc/autoconf.texi (Special Shell Variables): Mention
17023 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17025 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17026 MAILPATH and set PS1, PS2, PS4 to default values, to work
17027 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17028 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17029 the Autoconf documentation specifies; fall back to "unset" only if
17030 this fails. Use a shell for-loop for this rather than an m4 loop,
17031 to shorten the output script.
17033 2002-08-30 Paul Eggert <eggert@twinsun.com>
17035 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17036 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17037 for the CDPATH problem. Document PWD.
17038 (Limitations of Builtins): Document the problem that "cd $foo" and
17039 "ls $foo" may refer to different directories in shells conforming
17040 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17041 example, since the old example is now out of date.
17043 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17044 FOO" and "ls FOO" talk about different directories; this catches
17045 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17048 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17049 of rolling our own unset.
17050 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17051 in practice we needn't worry about CDPATH if unset doesn't work.
17053 * Makefile.in, aclocal.m4, bin/Makefile.in,
17054 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17055 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17056 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17057 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17058 tests/Makefile.in: Regenerate with Automake 1.6.3.
17060 * config/config.guess, config/config.sub, config/mkinstalldirs:
17063 * configure: Regenerate with self.
17065 2002-08-30 Kevin Ryde <user42@zip.com.au>
17067 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17070 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17072 * bin/autom4te.in (Request::load): Correctly test for "do" read
17075 2002-08-29 Akim Demaille <akim@epita.fr>
17077 * lib/Autom4te/General.pm (&xqx): New.
17078 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17079 hand, which is not portable.
17081 * bin/autom4te.in: Use them.
17082 Use &error instead of die.
17083 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17086 2002-08-17 Paul Eggert <eggert@twinsun.com>
17088 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17089 default list of compilers to try, since it was long ago superseded
17090 by the ksh fc builtin. Suggested by Steven G. Johnson.
17092 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17094 * doc/autoconf.texi (Invoking autom4te): End the option table,
17095 fixing a bug introduced by the previous patch.
17096 (Limitations of Make): Add a 'target lookup' subentry in the
17097 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17099 2002-07-29 Mark D. Roth <roth@feep.net>
17101 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17102 options and use $AUTOM4TE_PATH.
17103 * doc/autoconf.texi: Remove documentation of autom4te
17104 --include-envvar and --site-macro-subdir options and document
17105 use of $AUTOM4TE_PATH.
17106 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17107 arguments from each language section.
17109 2002-07-29 Paul Eggert <eggert@twinsun.com>
17111 * doc/install.texi: Include copyright symbol in copyright notice.
17113 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17115 (AM_MAKEINFOFLAGS): New macro.
17116 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17117 * Makefile.am (INSTALL): Use the new macros.
17118 Use -o rather than --output, since "missing" does not grok --output.

17406 This improves on an earlier suggestion by H. Peter Anvin.
17408 2002-05-16 Paul Eggert <eggert@twinsun.com>
17410 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17411 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17412 Both macros now accept an optional source-dir arg.
17413 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17415 * NEWS: Document this.
17416 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17418 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17419 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17420 not for GNU extensions; this undoes part of the 2000-11-03 change,
17421 reverting to 2.13-compatible behavior.
17422 Add new optional argument DIR.
17423 (AC_FUNC_FNMATCH_GNU): New macro.

17429 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17430 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
17431 and it causes a 'test' syntax error if it fails.
17432 Bug reported by Stephen Gildea.
17434 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17435 If prototypes are supported, use them to check this at compile-time,
17436 instead of trying to check it at run-time. If we must do a run-time
17437 check, assume that setvbuf is standard when cross-compiling, as
17438 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17439 Bug reported by Paul D. Smith.
17441 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17442 argument specifying location of getloadavg.c. This removes a
17443 FIXME. This idea was taken from Jim Meyering's implementation in
17445 * doc/autoconf.texi (Particular Functions): Document this.
17446 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17447 that's what the code does; this fixes a bug reported by

17452 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
17453 autopoint instead of gettextize.
17454 ($uses_alocal): Rename as...
17455 ($uses_aclocal): this.
17456 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17457 Suggested by Bruno Haible.
17459 2002-05-03 Akim Demaille <akim@epita.fr>
17461 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
17463 2002-04-29 Paul Eggert <eggert@twinsun.com>
17465 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17466 files to be 1 second older; just set them to be the same time.
17467 Also, sleep 1 second after the first aclocal, to work around
17468 problems with sub-second time stamps on the input files.
17470 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17472 * doc/autoconf.texi: Mention "set -e -x" lossage
17473 under node "Limitations of Builtins".

17479 From Christian Cornelssen.
17481 2002-04-29 Akim Demaille <akim@epita.fr>
17483 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17484 of lack of $LINENO support, then the test will compare the $LINENO
17485 in testsuite vs. the lineno in the test file. This is wrong, of
17487 Be sure to protect it.
17488 Reported by Patrick Welche.
17490 2002-04-25 Akim Demaille <akim@epita.fr>
17492 * doc/autoconf.texi (Obsolete Macros): Typo.
17493 Reported by Vladimir Volovich.
17495 2002-04-25 Akim Demaille <akim@epita.fr>
17497 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17498 than some of the input files, hence, on the second run of aclocal,
17499 if some of its input are younger, make them older.
17500 Suggested by Paul Eggert.
17502 2002-04-25 Akim Demaille <akim@epita.fr>
17504 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17510 and ac_subst_vars be sh variables containing the list of
17511 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17513 (_AC_INIT_PREPARE): Use them to log them.
17514 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17515 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17516 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17517 _AC_SUBST_FILES and _AC_SUBST_VARS.
17518 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17520 2002-04-24 Akim Demaille <akim@epita.fr>
17522 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17523 autoheader, so that automake does not complain about a missing
17524 config.h.in that was to be created.
17526 2002-04-23 Akim Demaille <akim@epita.fr>

17608 that is not portable to Zsh.
17610 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
17612 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
17613 from aclocal.m4 too.
17615 2002-04-12 Akim Demaille <akim@epita.fr>
17617 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
17619 2002-04-10 Akim Demaille <akim@epita.fr>
17621 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
17622 workaround for ${1+"$@"}.
17623 * doc/autoconf.texi (Shell Substitutions): Explain it.
17624 From Oliver Kiddle and Peter Stephenson.
17626 Have M4sh perform minimal shell sanitizing.
17628 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
17630 (_AS_PREPARE): this new macro.
17632 (AS_INIT): Invoke AS_SHELL_SANITIZE.
17633 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
17635 Adjust Autoconf and Autotest.
17637 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
17638 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
17639 * lib/autotest/general.m4 (AT_INIT): Likewise.
17640 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
17641 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
17644 Use this M4sh to generate Autoconf's shell scripts.
17646 * tests/wrapsh.as: New, precursor of wrapsh.in.
17647 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
17648 on Autotest and M4sh.
17649 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
17650 (wrapsh.in): New target.
17651 * bin/autoconf.as: New, precursor of autoconf.in.
17652 (autoconf.in): New target.
17654 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

17657 with indented comments in rules.

17672 directories when descending in a SUBDIRS.
17673 Reported by Ezra Peisach.
17675 2002-04-04 Andreas Schwab <schwab@suse.de>
17677 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
17678 contains no literal separators.
17680 2002-04-03 Akim Demaille <akim@epita.fr>
17682 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
17683 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
17684 Use dnl, not the KILL diversion.
17686 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
17687 (AC_CONFIG_LINKS): here.
17689 Don't use the KILL diversion, as it kills spurious output, which
17690 results in failures being hidden.
17691 Use m4_defn where appropriate.
17692 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
17693 after the second argument.
17695 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
17696 syntax, as it is provided by M4sugar.
17697 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
17699 2002-04-03 Andreas Schwab <schwab@suse.de>

17713 (_AC_COMPILER_OBJEXT): Use them.
17714 Fixes Debian #138666.
17716 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
17718 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
17720 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
17721 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
17722 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
17723 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
17724 (AC_C_CONST): Same.
17725 (AC_C_INLINE): Same.

17738 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
17739 to avoid versions of HP C which don't allow that.
17741 2002-03-27 Paul Eggert <eggert@twinsun.com>
17743 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
17744 (AS_SHELL_SANITIZE): Invoke it.
17745 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

17751 2002-03-26 Akim Demaille <akim@epita.fr>
17753 * doc/autoconf.texi (Introduction): The GNATS base moved.
17755 2002-03-25 Paul Eggert <eggert@twinsun.com>
17757 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
17758 as POSIX requires, as it doesn't work with Zsh.
17759 * doc/autoconf.texi (Assignments): Document the problem.
17761 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17763 * doc/autoconf.texi (Limitations of Make): Mention more issue
17764 about VPATH, overriding of macros in sub-makes, and handling of
17767 2002-03-21 Paul Eggert <eggert@twinsun.com>
17769 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17770 problem with here-document buffer boundaries.
17772 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17773 when reinvoking the shell, to work around problems with installers
17774 who put strange things like "cd" commands in their environments.
17776 2002-03-19 Akim Demaille <akim@epita.fr>
17778 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

17790 From Nishio Futoshi.
17792 2002-03-19 Akim Demaille <akim@epita.fr>
17794 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

17798 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17799 (Limitations of Usual Tools): Add mkdir section.
17801 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17802 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17803 back on AS_DIRNAME to compute prefixes otherwise; this is
17804 roughly what mkinstalldirs does. That way, we need not have
17805 our own filename disassembler. The old disassembler did not
17806 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17808 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17809 Create at_test_all by a series of assignments,
17810 not by a single assignment of a long string. The latter causes ksh
17811 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17812 presumably because of a buffer overrun.
17814 2002-03-14 Paul Eggert <eggert@twinsun.com>
17816 * lib/autotest/general.m4 (at_times_skip):
17817 Renamed from at_times. Now a boolean.
17818 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17819 says 'times: not found'.
17821 2002-03-14 Akim Demaille <akim@epita.fr>
17823 * bin/autoreconf.in (&study_gettextize): New.
17824 (&autoreconf): Handle newest gettextize.

17848 2002-03-11 Andreas Schwab <schwab@suse.de>
17850 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
17851 does not do it if --with-lispdir is given.

17860 subdirectory should exist.
17862 2002-03-08 Akim Demaille <akim@epita.fr>
17864 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17866 2002-03-08 Akim Demaille <akim@epita.fr>
17868 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17869 aliases the actual variables, and modifications of the former
17872 2002-03-08 Akim Demaille <akim@epita.fr>
17874 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17875 because of C-c: have m4 output in tmp files, then mv them.
17877 2002-03-08 Akim Demaille <akim@epita.fr>

17898 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17899 * lib/autoconf/general.m4 (AC_INIT): More informative error
17900 message for LIBOBJ.
17902 2002-03-04 Akim Demaille <akim@epita.fr>
17904 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
17907 2002-03-04 Akim Demaille <akim@epita.fr>
17909 * doc/autoconf.texi (Transforming Names): Equality between target
17910 and host is irrelevant.
17911 (Specifying Names, Canonicalizing): Remove all references to the
17912 backward compatibility hooks. Rather, collect them all into...
17913 (Hosts and Cross-Compilation): this new section.
17914 * doc/install.texi (System Type): Ditto.
17915 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17916 that `--host' implies cross-compilation.
17918 2002-03-04 Akim Demaille <akim@epita.fr>
17920 * doc/autoconf.texi (Evaluation Macros): New.
17921 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17923 (_m4_foreach): Define the variant with immediate evaluation so
17924 that it contains exactly the items, not an expression which
17925 evaluation is the current item.
17926 (m4_re_string, m4_re_word): Don't over quote them.
17928 2002-03-04 Akim Demaille <akim@epita.fr>
17930 Instead of having stacking `shift's evaluated at the end, let
17931 `foreach' loops immediately evaluate them.
17933 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17934 $*. This is the n-th time I change my mind, but hopefully this is
17937 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17939 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17940 it was only a hack for m4_text_wrap.
17941 (m4_car2): Remove, replaced by...
17943 (_m4_foreach): Adjust.
17944 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17945 m4_bpatsubst for clarification.

17996 Fix Autoconf PR/207:
17997 AC_PREFIX_PROGRAM fails with dashed program names
17999 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
18000 variable when looking for the prefix program.
18001 Now it also works for shell variables.

18036 2002-02-05 Akim Demaille <akim@epita.fr>
18038 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

18055 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

18058 2002-02-05 Akim Demaille <akim@epita.fr>
18060 * bin/autom4te.in (&parse_args): Implement `frozen files are
18061 optional are the sum of the previous files on the command line'.
18062 Also, pass `--reload-state=' on them, so...
18063 (handle_m4): don't.
18064 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18065 (M4sh): Rely on M4sugar.
18066 (Autotest, M4sh, M4sugar): Use frozen files.
18068 2002-01-31 Akim Demaille <akim@epita.fr>
18070 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

18076 alphanumeric to `-' instead of `_'.
18078 2002-01-30 Akim Demaille <akim@epita.fr>
18080 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one

18082 is now run with GCC only.
18083 * doc/autoconf.texi (Compilers and Preprocessors): New.

18092 2002-01-29 Akim Demaille <akim@epita.fr>
18094 * tests/torture.at (Configuring subdirectories): Use configure.in,
18095 so that aclocal 1.4 works.
18096 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18098 2002-01-28 Akim Demaille <akim@epita.fr>
18100 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18103 2002-01-28 Akim Demaille <akim@epita.fr>
18105 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18106 AUTOTEST_PATH *after* it was set.
18107 Don't put `.' in the PATH: the user should be precise and `./' if
18108 needed. In addition, given that the test suite does some `cd', if
18109 `.' is in the path, the `tested programs' sections will report
18110 programs found in the test suite's directory, while during the
18111 tests (performed in their own directory), these programs are no

18179 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
18180 package.m4, since is really depends upon configure.ac, not
18182 * doc/autoconf.texi (testsuite Scripts): Adjust.
18183 * tests/Makefile.am (package.m4): New.
18184 EXTRA_DIST it since its a source.
18186 2002-01-06 Akim Demaille <akim@epita.fr>
18188 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18189 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18190 and PACKAGE_BUGREPORT from here...
18191 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18193 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18194 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

18218 2001-12-14 Akim Demaille <akim@epita.fr>
18220 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18221 trailing files, don't apply `-rf' to files which might not be
18222 created by configure (core, core.*, and *.core), but just `rm -f'.
18223 Suggested by Jonathan Kamens.
18225 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18227 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

18236 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18237 abs_srcdir, top_srcpath to abs_top_srcdir.
18238 (_AC_OUTPUT_FILES): Adjust.
18239 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,

18249 2001-12-12 Kevin Ryde <user42@zip.com.au>
18251 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18252 forbidden file descriptors table.
18254 2001-11-26 Akim Demaille <akim@epita.fr>
18256 * bin/autoscan.in (%c_keywords): Build it at top level.

18261 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18262 Remove $filepath, useless.
18263 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18264 variables, they are really part of the tokens.
18265 Split the input line on spaces and then look for tokens.
18266 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18267 because of `lex$U.$(OBJEXT)'.
18268 (&scan_files): Use "@list" instead of join.
18269 * doc/Makefile.am (CLEANFILES): Add *.fns.

18274 Remove, replaced by...
18275 * tests/wrappl.in: Be common for all the Perl executables.
18276 In particular autoscan and autoheader want -I.
18277 * configure.ac: Adjust.
18278 * lib/autoscan/headers: errno.h is portable.
18280 2001-11-26 Akim Demaille <akim@epita.fr>
18282 * bin/autoscan.in (used): New.
18285 2001-11-26 Akim Demaille <akim@epita.fr>
18287 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18289 (&scan_sh_file): Remove a duplicate pattern.

18296 Before, having a line containing the opening of a multi line
18297 comment made the whole line be ignored.
18299 2001-11-26 Akim Demaille <akim@epita.fr>
18301 * doc/autoconf.texi (Using an Autotest Test Suite): New.

18307 Test groups are now run two directories deeper.
18309 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18310 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18312 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18313 top_srcdir, builddir and top_builddir.
18314 Use `at_*dir' relatively to the directory containing the
18315 suite, use `*dir' when relatively to the current group dir.
18317 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18319 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18320 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18321 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18324 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18326 * doc/autoconf.texi (Using System Type): Add an example of `case
18327 $host' usage so people quit using `case $target' everywhere.
18329 2001-11-22 Akim Demaille <akim@epita.fr>
18331 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18332 spotted by Jim Meyering.
18334 2001-11-16 Paul Eggert <eggert@twinsun.com>
18336 This patch implements a `long double' suggestion by Oliver Kiddle.
18338 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18339 static, to catch errors if the value isn't known at compile-time
18340 and the compiler supports dynamic arrays. Change its name from
18341 `_array_' to `test_array' to avoid potential name clashes.
18342 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18343 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18344 better than double. Catch a bug in GCC 2.95.2 x86.
18345 * doc/autoconf.texi (C Compiler): Document the above.
18348 2001-11-13 Akim Demaille <akim@epita.fr>
18350 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18352 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18354 2001-11-13 Akim Demaille <akim@epita.fr>
18356 * lib/autotest/general.m4 (AT_INIT): After having run the test
18357 group, go back to the initial directory, not to at_suite_dir.
18359 2001-11-13 Akim Demaille <akim@epita.fr>
18361 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18362 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18363 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18365 (AT_CHECK_CONFIGURE): Use absolute paths.
18366 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18367 The problem is still the old one: there is no means in M4 (that I
18368 know about) to create a defining macro, because there is no means
18369 to create `$1' etc., therefore, the defining macro ``swallows''
18370 all the arguments meant to the defined macro.
18372 2001-11-13 Akim Demaille <akim@epita.fr>
18374 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18375 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18377 * tests/aclocal.m4: Remove, as it is no longer used.
18379 2001-11-13 Akim Demaille <akim@epita.fr>
18381 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18382 variable names when referring to a single test group, or to
18383 `suite' when referring to the whole test suite.
18384 `at_last_test' is removed: m4 compute at_format itself.
18385 (at_stdout, at_stder1, at_stderr): New variables.
18386 (AT_CHECK): Use them.
18388 2001-11-13 Akim Demaille <akim@epita.fr>
18390 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18392 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18393 Do it as soon as a test fails, don't wait till the end of the test
18395 Don't remove $as_me.[0-9]*, since these files no longer exist.
18397 2001-11-13 Akim Demaille <akim@epita.fr>
18399 * tests/tools.at: Use absolute paths, since we are no longer run
18402 2001-11-13 Akim Demaille <akim@epita.fr>
18404 Now that tests are running in their own private dir, there is no
18405 need to list the files to remove at the end of tests groups.
18407 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18408 (AT_data_files, at_data_files): Remove.
18409 (AT_CLEANUP, AT_DATA): Simplify.
18411 Remove the group dir if !debug && !failed.
18412 * tests/atspecific.m4: Adjust.
18414 2001-11-13 Akim Demaille <akim@epita.fr>
18416 Start a new layout for Autotest: `testsuite' creates
18417 `testsuite.dir' in which the at-check-line etc. files are to be
18418 found, and `testsuite.dir/003' where the test group 3 is run.
18420 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18421 at_check_line_file, at_format, at_test_normalized, at_group_dir
18423 Create the directories.
18424 Use absolute paths for at- files.
18425 (AT_CHECK): Adjust.
18427 2001-11-11 Michael Matz <matz@kde.org>
18429 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18431 (m4_car): Properly quote arguments.
18433 2001-11-13 Akim Demaille <akim@epita.fr>
18435 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18436 with stricter rules on LIBOBJS.
18438 2001-11-12 Paul Eggert <eggert@twinsun.com>
18440 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18441 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18444 2001-11-12 Akim Demaille <akim@epita.fr>
18446 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18448 2001-11-12 Akim Demaille <akim@epita.fr>

18451 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18452 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18453 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18454 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18455 specify to what the macro should be defined (typically to 1).
18457 2001-11-12 Akim Demaille <akim@epita.fr>
18459 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18462 2001-11-12 Akim Demaille <akim@epita.fr>
18464 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18465 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18466 definition used by Automake where LEX is +/- "${missing} lex" and
18467 `missing' itself contains variables.
18469 2001-11-12 Akim Demaille <akim@epita.fr>
18471 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18472 Now that M4sh pushes BODY, the comments were output at the end of
18475 2001-11-08 Akim Demaille <akim@epita.fr>
18477 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18478 that we can trace macros from aclocal.m4.
18479 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18480 obsoleted, and redirect to the former anyway.
18481 Reported by Ralf Corsepius.
18483 2001-11-08 Akim Demaille <akim@epita.fr>
18485 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18486 processed only if present.
18487 * tests/torture.at (Configuring subdirectories): Use autoreconf
18488 instead of successive calls to autoconf.
18489 Add a nonexistent subdirectory to exercise the patch above.
18490 Reported by Ralf Corsepius.
18492 2001-11-08 Kevin Ryde <user42@zip.com.au>
18494 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18495 doesn't accept .S files.

18503 (handle_output): Use it.
18504 Read m4_pattern_forbid with messages.

18508 * bin/autom4te.in (--normalize): Remove.
18509 * lib/autom4te.in: Adjust.
18511 2001-11-05 Akim Demaille <akim@epita.fr>
18513 * tests/Makefile.am (testsuite): Rename this target as...
18514 ($(TESTSUITE)): this.
18517 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18519 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18520 the --prefix option, also remove it's argument.
18522 2001-11-05 Akim Demaille <akim@epita.fr>
18524 * doc/autoconf.texi (testsuite Invocation): Update.
18525 (Writing testsuite.at): Update.

18534 (&file_name_is_absolute): New, wrappers around routines from
18536 Use and export them.
18537 (&find_configure_ac): Optionally take a directory where to look at.
18538 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18540 Default @ARGV to `.', not find_configure_ac.
18541 (&autoreconf): Argument is a directory.
18542 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18543 * doc/autoconf.texi (autoreconf Invocation): Update.
18545 2001-11-03 Akim Demaille <akim@epita.fr>

18549 Add basename, dirname, and fileparse.
18551 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18552 Don't look for aclocal flags if we already know aclocal is not
18554 Move aclocal.m4t only if it exists.
18555 Reported by Ezra Peisach.
18557 2001-11-03 Akim Demaille <akim@epita.fr>
18559 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18560 passed on command line, defaulting to ./configure.ac if present.
18561 (&maybe_autoreconf, File::Find): Remove, unused.
18562 (&autoreconf): If autoconf is not used, don't try to trace.
18564 2001-11-02 Akim Demaille <akim@epita.fr>

18581 Don't run aclocal when aclocal.m4 is not from aclocal.
18583 Don't run libtoolize and gettextize if --install is not given.
18585 2001-11-01 Paul Eggert <eggert@twinsun.com>
18587 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18588 be invoked before _AS_LINENO_PREPARE.
18589 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18590 than character ranges.
18592 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18593 invoking AS_BASENAME. Set the locale variables to 'C' if
18594 possible, as POSIX requires this to get the traditional

18598 2001-10-31 Paul Eggert <eggert@twinsun.com>
18600 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18601 with {}, as that triggers a bug in Bash 2.05.
18603 (_AS_LINENO_PREPARE): Use Sed rather than
18604 Awk. Fix the sed prepass to work even if there are multiple
18605 instances of $LINENO on the same line. Do not substitute for
18606 other variables like $LINENOT. Do not check file dates; such a
18607 check is unreliable on sufficiently fast machines, and removing
18608 the check makes the code simpler and more reliable. Check for
18609 output and chmod failures.
18611 * doc/autoconf.texi (Special Shell Variables): Document
18614 2001-10-31 Akim Demaille <akim@epita.fr>

18626 2001-10-26 Paul Eggert <eggert@twinsun.com>
18628 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
18629 lib/Autom4te/Struct.pm:
18630 Require Perl 5.005_03 instead of just 5.005, as some tests fail

18634 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18636 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18637 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

18657 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18658 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18659 POSIX decided to standardize on the int flavor of strerror_r.
18660 Always do char* test, as there's no reason not to.
18661 Assign to a char* var, to catch strerror_r that returns int*.
18663 * doc/autoconf.texi (Particular Functions):
18664 Document the above changes. Also, document the fact that
18665 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

18689 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
18691 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
18692 `intl' is already present, as it refuses unless --force.
18693 (&parse_args): Use -I, --include instead of the old Autoconf
18695 ($localdir, $autoconf_dir): Remove.
18697 (&maybe_autoreconf): New, to preserve $_ for File::Find.
18699 2001-10-19 Jens Petersen <petersen@redhat.com>

18720 configure.ac being studied.
18722 2001-10-18 Paul Eggert <eggert@twinsun.com>
18724 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

18729 (AS_BASENAME_EXPR): New macro.
18730 (AS_BASENAME_SED): Do not assume GNU sed semantics.
18731 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
18732 and fall back on 'sed' only if the other two fail. This makes
18733 AS_BASENAME act more like AS_DIRNAME.
18734 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
18735 contains white space.
18736 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

18793 2001-10-08 Akim Demaille <akim@epita.fr>

18886 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

18971 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

19112 * tests/Makefile.am (package.m4): Remove.
19114 2001-09-22 Akim Demaille <akim@epita.fr>
19116 Rely on `$LINENO' when possible instead of `__oline__'.

19119 `$LINENO' support replacement when not supported.
19120 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

19165 arguments. Fixed a typo.
19167 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19169 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
19170 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
19172 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19174 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

19183 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
19184 already have $file). Set output files to binary mode (helps avoid
19185 CR issues on DOSish systems).
19187 2001-09-19 Akim Demaille <akim@epita.fr>
19189 * lib/autotest/general.m4: Englishoes.
19190 From Tim Van Holder and Alexey Mahotkin.
19192 2001-09-18 Paul Eggert <eggert@twinsun.com>
19194 * doc/autoconf.texi (Common Shell Constructs): New node,
19195 documenting AS_DIRNAME.
19196 (Limitations of Usual Tools): Refer to it when discussing dirname.
19197 Also, update discussion of POSIX standard to reflect latest draft.
19199 * lib/autoconf/c.m4:
19200 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19202 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19203 Do not pass a first argument with leading '-'
19204 to expr, by parenthesizing initial integers that might be negative.
19206 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19207 now merely checks whether it is an error to pass an argument
19210 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19211 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19212 whether it is a (compile-time) error to pass an argument to
19213 getpgrp. This simpler test supports the revised documentation,
19214 and is all that AC_FUNC_GETPGRP's users really need.
19216 2001-09-18 Akim Demaille <akim@epita.fr>
19218 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19228 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19230 Add test for AS_BASENAME.
19231 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19232 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19233 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19234 * tests/base.at: Fixed the expected responses. The old ones were
19236 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19237 the documentation claims it should (and how it behaved in 2.13).
19239 2001-09-18 Akim Demaille <akim@epita.fr>
19241 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19242 the AC_CONFIG_COMMANDS invocation.
19243 This also solves the name clash problems.
19244 Don't set the package's ID.
19245 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19246 No longer to be shipped.
19247 (version.in): Remove.
19248 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
19249 * lib/autoconf/status.m4: Adjust.
19250 Use `m4_PACKAGE_STRING'.
19251 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19252 the only optional argument is the name of the test suite.
19253 Expect `package.m4' to define the package signature.
19254 * lib/autom4te.in (Autotest): Add `package.m4?'.
19255 * tests/Makefile.am (package.m4): New.
19256 * tests/suite.at: ifnames is a victim.
19258 2001-09-18 Akim Demaille <akim@epita.fr>
19260 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19261 AC_LIBSOURCE, AC_CONFIG_FILES.
19262 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
19263 program version string doesn't match the package's.
19264 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

19275 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19276 Always include <stdio.h> and <stdlib.h>. Evaluate
19277 the expression in an extra function before these includes. Call
19278 fprintf "%d" only after ensuring the argument is of type 'int'.
19279 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19281 2001-09-17 Paul Eggert <eggert@twinsun.com>
19283 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19284 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19285 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19286 when they don't exist.
19288 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19289 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19292 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19293 version with the version used by fileutils 4.1, except use
19294 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19297 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
19299 2001-09-13 Akim Demaille <akim@epita.fr>

19339 * lib/autotest/general.m4 (AT_INIT): Create and remove
19340 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19341 test suites can cohabit.
19343 2001-09-13 Akim Demaille <akim@epita.fr>
19345 * tests/mktests.sh: Don't output banners for empty test files.

19397 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

19400 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

19451 2001-09-05 Akim Demaille <akim@epita.fr>
19453 Be ready to handle filenames as stupid as `dnl.at', for if even
19454 the maintainer is dumb enough to do that...
19456 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19457 excellence in M4 quotation: consider `__file__' is active.
19459 And BTW, when invoking m4, pass the --include in the right order:
19462 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

19490 New, extracted from main.
19491 Use IO::File wherever possible.

19528 2001-08-31 Akim Demaille <akim@epita.fr>
19530 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

19536 to m4sugar was lacking!
19538 2001-08-31 Akim Demaille <akim@epita.fr>
19540 * man/Makefile.am (.x.1): We really have to pass
19541 autom4te_perllibdir.
19543 2001-08-31 Akim Demaille <akim@epita.fr>
19545 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

19608 Map --localdir, --autoconf-dir onto it.
19609 Forward autom4te's options instead of interpreting them.

19611 There is no such envvar since the inception of autom4te.cfg.

19639 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19641 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19642 indeed related to running the test suite, while passing

19644 Autoconf executables. So don't do that, leave it to...

19646 * tests/autoscan: New.
19647 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19666 2001-08-29 Akim Demaille <akim@epita.fr>

19693 foo=`(command) 2>/dev/null`

19934 * NEWS, README, README-alpha, TODO, tests/README: This package is
19935 `Autoconf', not `autoconf' (the executable).

19991 * lib/autoconf/general.m4, lib/autoconf/specific.m4,

20136 2001-08-15 Akim Demaille <akim@epita.fr>
20138 * bin/autom4te.in (@m4_warning): New.

20210 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20212 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20213 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20214 * doc/autoconf.texi (C Compiler Characteristics): Update

20220 magic values from an object file when cross-compiling.
20221 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20223 2001-08-10 Akim Demaille <akim@epita.fr>
20225 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20227 Suggested by Russ Allbery.
20229 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20231 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20232 current $prefix to the sub-configures.
20234 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20236 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20237 extension (needed on BeOS). Reported by Guido van Rossum.
20239 2001-08-09 Akim Demaille <akim@epita.fr>
20241 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20243 2001-08-07 Akim Demaille <akim@epita.fr>
20245 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20247 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20248 No need to remove the files before and after the each test, before
20249 each test and at the end of the suite is enough.
20250 Display only the children `times', not the shell's.
20251 If the test failed or was skipped, at-times is not available.
20253 2001-08-07 Akim Demaille <akim@epita.fr>
20255 Always produce testsuite.log, including when there are no
20256 failures. This helps getting information on skipped tests, and
20257 duration of the tests. Err, implement the latter btw.
20259 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20260 Dump information on the first run of each test.
20261 (AT_CLEANUP): Create `at-times' containing the duration of the
20264 2001-08-07 Akim Demaille <akim@epita.fr>
20266 The use of `dumpstat' revealed that `len' was used although it
20267 should not. m4_text_wrap was using it, but in the Autoconf world
20268 where it is legal. Hence (i) test M4sh in its own world, not
20269 Autoconf's, and (ii), ahem, fix the bug :)
20271 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20272 does not like `' instead of [].
20273 (AT_INIT): Forbid `^_?AT_'.
20274 And don't output such tokens.
20275 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20276 `script.as', and `autom4te.cache'.
20277 Remove `empty' and `macro' which are no longer used.
20278 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20279 * tests/m4sugar.at: Use it.
20280 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20282 2001-08-07 Akim Demaille <akim@epita.fr>

20286 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20288 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20290 2001-08-04 Akim Demaille <akim@epita.fr>
20292 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20293 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20295 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20296 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20297 (AC_F77_MAIN): Likewise.
20299 2001-08-04 Akim Demaille <akim@epita.fr>
20301 Don't rely on M4sugar outputting the patterns in files, since we
20302 might process the output _without_ running m4, hence without these
20305 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20306 * bin/autom4te.in (@Request::includes): Remove, unused.
20307 (@Request::source): Rename as...
20308 (@Request::input): this.

20313 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20315 2001-08-04 Akim Demaille <akim@epita.fr>
20317 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20318 autoconf', i.e., in addition to caching traces, cache the output.
20320 * bin/autom4te.in (Request::cache): Rename as...
20321 (Request::id): this.
20322 ($cache, $icache, $tcache, $ocache): New.

20325 (&up_to_date_p): Check that the output cache is up to date too.
20326 (top level): Run `&handle_m4' iff force or the cache is invalid.

20329 2001-08-04 Akim Demaille <akim@epita.fr>
20331 * bin/autom4te.in ($force): New.
20332 (&parse_args, &print_usage): -f, --force is a new option.
20333 (&handle_output): CPP directives might have spaces after `#'.
20334 (&parse_args): The first file only can be frozen.
20336 2001-08-04 Akim Demaille <akim@epita.fr>
20338 Don't let autom4te compute the `include' traces several times:
20339 first check that the trace cache file is up to date, and then
20340 compare its timestamp with that of the output.
20342 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20343 the preamble. Don't require 5.005 as Autom4te::General does it,
20344 and better yet (use `use', not `require'!).
20345 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20346 Class::Struct as Autom4te::Struct.
20347 * lib/Autom4te/General.pm (File::stat): Use it.
20348 (&mtime): New, export it.
20349 * bin/autom4te.in: Use it.
20350 Declare `$req' is invalid if it is outdated.
20351 Don't declare it valid before saving it if something went wrong.
20353 2001-08-04 Akim Demaille <akim@epita.fr>

20356 must be proposed to the users.
20358 * bin/autom4te.in (@required_trace): Remove.
20360 (&parse_args, &print_usage): -p, --preselect is a new option.

20377 * bin/autoconf.in ($@): Work around the usual sh bug.
20380 2001-08-03 Akim Demaille <akim@epita.fr>
20382 Clean up the handling of the M4 builtins tracing exception.
20384 * bin/autom4te.in (Request::request): Don't complete M4 builtins

20401 (m4_divert_pop): Dump the whole diversion stack when a diversion
20403 * bin/autom4te.in (&handle_output): Remember of the first
20404 occurrence of a possibly undefined macro, not the last.
20405 Complain about the possibly undefined macros in the same order as
20406 the appear in the output.
20407 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20408 * tests/tools.at (autoconf: forbidden tokens, basic)
20409 (autoconf: forbidden tokens, exceptions): No longer sort
20410 autoconf's stderr, as it is now deterministic.
20411 Check that `dnl' is caught.

20433 `END', as `Autom4te::General::END' will be triggered.
20434 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20435 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
