534 AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
535 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
536 &s;" test into the main program, as C99 might plausibly be
537 interpreted as not requiring support for this construction in
538 static initializers. Remove the "#if defined __xlc__" stuff, as
539 the bug is not present in recent xlc implementations, and they
540 reject the test for other (valid) reasons. People using ancient
541 xlc versions, if any, are suggested to update to fixed versions.

2174 Work around DJGPP shell function return bug with command substitutions.
2175 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
2176 shell function which also contains a command substitution causes
2177 the shell to barf. For more details and a fix see:
2178 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
2179 Possible workaround include putting the `return' in a subshell
2180 or calling another function to set the status.
2181 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE_BODY)
2182 (_AC_COMPILE_IFELSE_BODY, _AC_LINK_IFELSE_BODY)

2205 2009-09-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2207 DJGPP fix: remove both conftest and conftest.exe.
2208 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
2209 and both `conftest' and `conftest.exe' with `-o conftest', but not
2210 with `-o conftest.exe'.
2211 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
2212 `conftest' without $ac_exeext suffix.
2214 DJGPP fix: do not try to source /dev/null as cache or site file.
2215 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
2216 load the cache or site file if it is `/dev/null', as DJGPP treats
2217 it as a regular file, but the shell then warns about it later.
2218 Fixes several test suite failures on DJGPP.

2235 * bin/autoupdate.in: Fix typos in comments.
2237 Improve autotest testsuite summary message.
2238 * lib/autotest/general.m4 (AT_INIT): Hint at the toplevel log
2239 only if not $at_debug_p. Always hint at the per-test output.
2241 Four new autoupdate tests, expected failures.

6985 2008-03-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6987 On MinGW, substitution of CR and 0xFF fails.
6988 * tests/torture.at (Substitute and define special characters):
6989 MinGW awk cannot handle 0xFF, and on MinGW, the test does the

6994 Pull in recent maintainer improvements from coreutils.
6995 * GNUmakefile (_is-dist-target): 'make distclean' should not
6997 (_dummy): Change directories before removing autom4te.cache.
6998 (check dist distcheck install) [!_have-Makefile]: Provide nicer
7000 * configure.ac (AC_CONFIG_LINKS): Copy GNUmakefile into VPATH
7001 builds, after initial bootstrap.

7045 2008-03-02 Jim Meyering <meyering@redhat.com>
7047 Don't infloop upon "make dist".
7048 * GNUmakefile: Merge from coreutils.
7049 * Makefile.am (dist-hook): Inject .tarball-version into tarball,
7051 * configure.ac (AC_INIT): Use .tarball-version, not .version.

7068 Be nice with file systems that don't handle unusual characters.
7069 * tests/atlocal.in (func_sanitize_file_name)
7070 (func_sanitize_dir_name): New shell functions.
7071 * tests/tools.at (autom4te and whitespace in file names)
7072 (autotools and whitespace in file names): Use them.
7073 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7074 Cover more potentially problemtic file names. Use the new
7077 Properly handle funny file names for headers in config.status.
7078 The test suite did not cover this bug because the code was not
7079 quoting properly the arguments of `rm -f' (which "fails" silently)
7080 as well as the arguments of `diff' (whose output was redirected to
7081 /dev/null so we couldn't see its error message).
7082 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
7083 file names passed to `rm' and `diff'.
7084 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7085 Add a regression test.

7100 Ignore stderr for `./run' which fails to remove the
7101 busy test directory on w32.

7176 Fix regression in handling VAR=VALUE arguments to testsuite.
7177 * lib/autotest/general.m4 (AT_INIT) <PARSE_ARGS_END>: Detect

7193 forks when sanitizing PATH. Always output machine information,
7194 not just when atconfig was located.
7196 Add 'testsuite -C dir'.
7197 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
7199 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
7201 <DEFAULTS>: Delay computation of variables based on $at_dir...
7202 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
7203 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
7204 <PARSE_ARGS>: Parse new option.
7205 <HELP_TUNING>: Document it.
7206 * tests/autotest.at (Choosing where testsuite is run): New test
7208 (Keywords and ranges): Add test for missing -k argument.
7209 * NEWS: Document this.
7210 * doc/autoconf.texi (testsuite Invocation): Likewise.
7212 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7214 * build-aux/config.guess, build-aux/config.sub,
7215 build-aux/texinfo.tex: Sync from gnulib.
7216 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
7219 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7221 * doc/autoconf.texi (Particular Programs): Do not mention the
7222 Autoconf version in which the AC_PROG_INSTALL change was done.
7223 Suggested by Paul Eggert.
7225 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7227 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
7228 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
7229 mode, we change to the source directory, also set $ac_pwd so we
7230 do not go back to the build tree for the next config subdir.
7231 * tests/torture.at (Deep Package): Extend test to contain two
7232 config subdirs on the top level.
7234 Fix parallel `maintainer-check'.
7235 * Makefile.am (maintainer-check-tests): Depend on `all'.
7236 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
7237 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
7239 (maintainer-check): Serialize the testsuite runs.

7263 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7265 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
7266 check_SCRIPTS. Building the wrappers for `all' allows help2man
7267 to use them for the manpages.
7268 Report by Benoit Sigoure.
7270 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
7272 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7285 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7286 (m4_require): Use m4_do, not m4_join.
7288 Fix some whitespace tests on cygwin.
7289 * tests/tools.at (autom4te and whitespace in file names): Restore
7290 font-lock. Create $TMPDIR before it might be used.
7292 Fix spurious testsuite failure with M4 1.4.11.
7293 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
7295 Optimize AC_REQUIRE.
7296 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
7297 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7298 (m4_require): Avoid extra macro calls.
7300 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7302 * tests/torture.at (srcdir): Fix quoting.
7304 Do not pass top_srcdir to configure scripts in testsuite.
7305 * tests/autotest.at (srcdir propagation): Copy install-sh to
7307 (my only test): Drop setting of `top_srcdir'.
7308 * tests/base.at (Input/Output): Likewise.
7309 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
7310 config.guess, and config.sub to test source tree.
7311 Drop AC_CONFIG_AUX_DIR setting.
7312 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
7313 * tests/torture.at (Substitute a 2000-byte string): Drop
7314 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
7315 (Substitute a newline, datarootdir workaround): Likewise.
7316 (Define a newline): Adjust for linenumber changes in configure.ac.
7317 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
7319 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
7320 if `pwd` contains whitespace.
7322 Quote $abs_top_srcdir in tests.
7323 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
7324 * tests/tools.at (Syntax of the shell scripts): Likewise.
7326 * tests/m4sh.at (LINENO): Quote $0.
7328 Fix testsuite program wrapper for whitespace in `pwd`.
7329 The problem here is that the usual mantra is that command
7330 variables can contain arguments, thus we cannot just escape
7331 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
7332 $top_builddir/tests directory early in $PATH, so that the
7333 wrappers are found by their plain name.
7334 * tests/wrapper.as: Put $testdir early in $PATH.
7335 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
7337 Proper config.status --file/--header and $srcdir escaping.
7338 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
7339 characters in $ac_file_inputs.
7340 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs

7343 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
7345 Fix Autotest for whitespace in `pwd`.
7346 * lib/autotest/general.m4 (AT_INIT)
7347 <at_func_create_debugging_script, Driver Loop>:
7348 Quote $at_group_dir.
7349 * tests/autotest.at (whitespace in absolute testdir): New test.
7351 * lib/autom4te.in: Quote @datadir@.
7353 Proper file name escaping in Autoconf programs and Perl modules.
7354 This includes escaping of characters special to the shell
7355 as well as special to Perl, e.g., leading `<' or `>'.
7356 For example, when $file starts with `>', `open ">$file"'
7357 wrongly tries to append to a different file.
7358 * bin/autoconf.as: Fix quoting for autom4te options.
7359 * lib/Autom4te/General.pm (shell_quote): New function, taken
7360 from coreutils, written by Jim Meyering.
7362 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
7364 * bin/autoreconf.in (parse_args): Likewise.
7365 * bin/autoscan.in (main): Likewise.
7366 * bin/autoupdate.in (main): Likewise.
7367 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
7368 * bin/ifnames.in: Likewise, XFile usage fixes.
7369 * tests/tools.at (autom4te and whitespace in file names): Extend
7370 test. Test twice, with special characters allowed on w32, and the
7371 rest. Test leading and trailing whitespace, for `open_quote'.
7372 (autotools and whitespace in file names): New, analogous test.
7373 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
7374 by Russ Allbery and Eric Blake.
7377 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
7378 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
7379 * lib/Autom4te/FileUtils.pm (open_quote): New function.
7380 (update_file, contents): Use it.
7382 * Makefile.am (autom4te-update): Rewrite for git.
7384 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7386 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
7388 Fix copyright years.
7389 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
7390 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
7392 2007-12-04 Eric Blake <ebb9@byu.net>
7394 Manually resync with gnulib, since 'make cvs-update' no longer works.
7395 * build-aux/config.guess: New upstream version.
7396 * build-aux/config.sub: Likewise.
7398 When using older automake, don't downgrade build-aux/texinfo.tex.
7399 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
7400 * doc/Makefile.am (TEXINFO_TEX): Add.
7402 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
7404 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
7405 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
7406 #undef as this runs afoul of our new way of creating config.h.
7407 Problem reported by Jim Meyering in
7408 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
7410 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7412 Fix autom4te for unusual characters in input file names.
7413 * bin/autom4te.in (files_to_options): Quote active characters
7415 * tests/tools.at (autom4te and white space in file names):
7418 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
7419 Document that Tru64 awk always splits $0.
7421 2007-11-24 Stepan Kasal <kasal@ucw.cz>
7423 * lib/autotest/general.m4 (AT_INIT): Do not extract the
7424 `#AT_STOP_...' line at the end of each test.
7426 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7428 * lib/autotest/general.m4 (AT_INIT): For awk line number
7429 extraction script, ensure `$at_group' has a defined value
7430 even for the empty set, and properly quote its usage inside
7433 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7435 * doc/autoconf.texi (Shell Functions): New chapter. Document
7436 IRIX sh $0 issue in functions, move content from ...
7437 (Portable Shell): ... here.
7438 (Shell Script Compiler): Note that shell functions are not
7439 totally unportable any more.
7441 2007-11-22 Stepan Kasal <kasal@ucw.cz>
7442 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7444 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
7445 extracting the line numbers of the last needed test.
7447 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7449 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7452 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7454 Fix IRIX testsuite debugging failures: $0 in functions.
7455 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7456 Do not use $0 inside a function, as IRIX sh will set that to the
7457 function name rather than the script invocation name.
7459 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
7460 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7462 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
7463 to extract test scripts.
7464 (AT_INIT): Extract and cache test script line numbers.
7466 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7468 * lib/autotest/general.m4: Revert 2007-11-15 patch and
7469 subsequent fixups; the awk -> here-document conversion trashes
7470 performance too much with AIX sh.
7472 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7474 * tests/local.at: Do not test m4, perl with AT_TESTED.
7476 Diagnose and guard against write errors dealing with config.status.
7477 The general idea is this: all write failures from `configure'
7478 writing `config.status' are indicated by $ac_write_error, which
7479 is only checked at the end. This is safe because config.status
7480 code is not executed before the file is complete. Other write
7481 failures, be they inside config.status, or in sub shell/awk
7482 scripts spawned from configure or config.status, typically need
7483 earlier checking, as their results are used right afterwards.
7484 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7485 before writing config.status, check afterwards.
7486 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7487 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7488 Set `ac_write_error' for write failures to config.status. Barf
7489 upon write failures to temporary files.
7490 Adjust note about closing and reopening the here-document.
7491 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7492 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7493 reopening the here-document.
7494 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7495 Ensure `ac_write_error' does not escape into config.status.
7496 Also, add a couple of code paths not yet exercised in the test
7497 suite: a config file with input from stdin, and a config header

7501 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7503 Avoid error with Tru64 awk and testsuite lines with many words.
7504 * lib/autotest/general.m4 (AT_INIT): In the awk script that
7505 reads the testsuite, set the field separator to an unusual value,
7506 in order to not run over the limit of 199 fields. Tru64 4.0D awk
7507 even splits the input if $i, i>0, was never accessed in the script.

7545 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
7546 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7548 * lib/autotest/general.m4 (at_func_test): Remove.
7549 (AT_INIT): Pre-extract test groups into separate files.
7550 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
7551 Remove at-test-source files together with the $at_group_dir.

7562 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
7565 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7567 * lib/autoconf/status.m4: Fix a couple of comment typos.
7569 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
7571 2007-11-13 Jim Meyering <meyering@redhat.com>
7573 Clean up the rule to create "expr".
7574 * tests/Makefile.am (expr): Don't redirect directly to target.
7575 Redirect just once, not for each echo statement.
7576 Use $@, not literal "expr".
7578 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>

7581 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7582 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7583 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7584 These no longer check for preprocessor flaws.
7585 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7586 Do not check for preprocessor flaws.
7588 2007-11-13 Jim Meyering <meyering@redhat.com>
7590 Adapt dependencies, now that a version change doesn't modify configure.ac
7591 * GNUmakefile: Remove "make clean" kludge.
7592 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not

7604 * doc/autoconf.texi (Limitations of Builtins): Document problem
7605 with { ... } a bit more clearly. Suggest ":;{" as a shorthand

7608 Use ":;{" shorthand.
7609 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7611 2007-11-12 Jim Meyering <meyering@redhat.com>
7613 Add more non-srcdir build support.
7614 * GNUmakefile (dummy): Split a long line.
7615 Add -v option to autoreconf invocation.
7617 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7618 * GNUmakefile (dummy): Remove INSTALL.
7620 Remove racy commands to build scripts in bin/ and tests/.
7621 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7622 are guaranteed to be built, remove the rules that tried to build
7623 them. Before, with a parallel build, these rules could lead to
7624 two processes writing tests/wrapper.in concurrently.
7626 Build in man/ only *after* building in bin/ and tests/.
7627 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7628 in both bin/ and tests/.
7630 Accommodate non-srcdir build-from-checkout.
7631 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7632 Use git's --git-dir=$srcdir/.git option.
7633 Add quotes, in case tarball_version_file contains shell meta-characters.
7634 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7635 * configure.ac: Pass "." to git-version-gen.
7637 Avoid spurious test failures due to version skew.
7638 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7640 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7642 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.

7660 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7662 Document that $((expression)) is not portable.
7663 * doc/autoconf.texi (Shell Substitutions): Here.
7665 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7667 Ignore configure --help* errors due to LINENO-impaired shells.
7668 * tests/torture.at (Configuring subdirectories, Deep Package):
7669 In the --help* tests in read-only trees, make `.' temporarily
7670 writable again for the `stderr' file, and ignore errors due to
7671 the attempt to write configure.lineno.
7672 Report by Patrick Welche.
7674 2007-11-10 Jim Meyering <meyering@redhat.com>
7676 Generate package.m4 in build-dir, not srcdir.
7677 * tests/Makefile.am (package.m4): Adjust target.
7678 Don't redirect directly to $@.
7679 (CLEANFILES): Add package.m4.
7680 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7682 When running $(AUTOTEST), search "." before searching $(srcdir).
7684 Avoid a race condition that would make parallel "distclean" fail.
7685 * tests/Makefile.am (distclean-generic): Replace the default,
7686 automake-provided rule with an identical one, but with an additional
7687 dependency on distclean-local. Simply adding the dependency would
7688 cause automake not to emit the rule at all.
7689 * BUGS: Building with -jN works, now.
7691 Distribute git-version-gen.
7692 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7693 since GNUmakefile is distributed, and requires it for dist* rules.
7695 Remove two more generated files from version control.
7696 * INSTALL: Remove generated file.
7697 * lib/autoscan/autoscan.list: Remove generated file.
7699 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7701 * GNUmakefile (PATH): Remove stray apostrophes; they become
7702 part of PATH, which isn't wanted here.
7704 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7706 New config files output variable `top_build_prefix'.
7707 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7709 * doc/autoconf.texi (Preset Output Variables): Document it.
7711 Report by Bob Friesenhahn.
7713 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7714 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7715 function, to parametrize arithmetic with expr vs. the shell.
7716 Use it where possible.
7717 Suggestion by Benoit Sigoure.
7719 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7721 Adjust the documentation of autotest WRT atlocal.
7722 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7723 when using Automake, to write a rule to produce atlocal, since it's
7724 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7725 distributed, not atconfig.in.
7727 2007-11-04 Eric Blake <ebb9@byu.net>
7729 Update list information.
7730 * README: Mention new autoconf-commit list.

7737 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7739 * build-aux/.gitignore: Ignore mkinstalldirs.
7741 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7743 2007-11-03 Jim Meyering <meyering@redhat.com>
7745 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7746 * build-aux/git-version-gen: This syncs from coreutils.
7748 Adjust the build procedure so "make check" works reliably.
7749 * README-hacking: Include an extra step between "make" and
7750 "make check" to ensure that the latter passes.
7752 Use just-built tools, when possible.
7753 * GNUmakefile (PATH): Set and export here, ...
7754 (dummy): ... rather than here.

7762 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7764 * configure.ac (AC_PREREQ): Require version 2.60, for
7765 AC_PROG_SED, AC_PROG_GREP.

7790 * build-aux/mdate-sh: Remove file.
7791 * build-aux/.gitignore: New file.
7792 Suggestion from Ralf Wildenhues.
7794 2007-11-03 Eric Blake <ebb9@byu.net>
7796 Adjust version comparison to account for git snapshot numbers.

7800 <m4_version_compare>: Document this change.
7801 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7803 2007-10-30 Bruno Haible <bruno@clisp.org>
7805 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7806 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7807 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7808 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7809 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7810 Suggested by Paul Eggert.
7812 2007-10-28 Jim Meyering <meyering@redhat.com>
7814 * README-hacking: Autoconf, Automake, and Perl are required to build.
7815 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7817 2007-10-28 Jim Meyering <meyering@redhat.com>
7819 README-hacking: Recommend running autoreconf -vi.
7820 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7821 so that we use just-built tools when they're available.
7822 Suggestions from Ralf Wildenhues.
7824 2007-10-28 Jim Meyering <meyering@redhat.com>
7826 Make inter-release --version output more useful.
7828 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7829 which indicates that it is built using the 19th change set
7830 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7831 is a prefix of the commit SHA1.
7832 * build-aux/git-version-gen: New file.
7833 * configure.ac: Run it to set the version.
7834 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7835 * Makefile.am (dist-hook): Arrange so that .version appears only
7836 in distribution tarballs, never in a checked-out repository.
7837 * .gitignore: Add .version here, too. Just in case.
7838 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7839 not configure.ac, now that the version number changes automatically.
7841 Ensure that $(VERSION) is up to date for dist-related targets.
7842 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7843 git-version-gen doesn't match $(VERSION), but only for dist targets.
7845 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9113 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
9114 AC_CHECK_TYPE, AC_CHECK_TYPES.
9115 * doc/autoconf.texi (Generic types): C types must be type-names
9116 (the C terminology), not type-ids (the C++ term). C++ types
9117 must not be anonymous.
9118 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
9119 for C++; this drops support for anonymous struct and union types,
9120 which were problematic anyway.

9139 with objects too. Document the restrictions on its use.
9140 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
9141 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
9142 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
9143 works but the latter doesn't, then it's a valid type.
9144 This lets people use function types and so forth.
9145 For C++ there doesn't seem to be a simple solution, so leave it alone.
9146 (AC_CHECK_SIZEOF): Allow argument to be a variable.
9147 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
9148 AC_CHECK_TYPE; that wasn't documented or necessary.
9150 2007-04-11 Stepan Kasal <kasal@ucw.cz>
9152 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

9205 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
9206 (Limitations of Usual Tools): Also list \< and \>, and mention that

9318 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
9319 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
9320 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
9321 substitution will still be done by the special code.

9366 discussion about the allow_superuser_privileges example,
9367 and change it a bit to make things clearer.
9368 (Optimization and Wraparound): Clarify whether the compiler
9369 will generate an infinite loop for the example derived from
9370 Autoconf's mktime test.
9371 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
9372 Also, clarify unsigned multiplication overflow.
9374 2007-01-04 Eric Blake <ebb9@byu.net>
9376 * bin/Makefile.am (RELEASE_YEAR): New macro.

9386 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
9388 * doc/autoconf.texi (Integer Overflow): Revised based on today's
9389 feedback. The most important changes document what happens when
9390 you convert an out-of-range value to a signed integer type, and
9391 say that (sum < a) != (b < 0) reliably detects overflow when sum =
9394 * doc/autoconf.texi (Integer Overflow): Greatly expand and
9395 rewrite, taking notions from the recent discussion on the gcc and
9396 autoconf mailing lists; please see
9397 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
9398 and follow the many links.
9399 (Integer Overflow Basics, Signed Overflow Examples):

9401 (Signed Integer Division): New sections.
9403 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
9405 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
9406 preprocessor macro arguments in traced name.
9407 * doc/autoconf.texi (Defining symbols): Document longstanding
9408 support for AC_DEFINE-ing macros with arguments, and document
9409 behavior when the same variable has multiple AC_DEFINEs.
9410 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
9411 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
9412 macros directly, giving much shorter and simpler code.
9414 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
9416 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
9417 space before "$ac_configure_args" to prevent a 'config.status
9418 --recheck' failure if ac_configure_args doesn't contain a leading
9419 space. This works around a problem with the XEmacs configure.ac,
9420 which uses the (undocumented) ac_configure_args variable
9421 inconsistently with Autoconf.
9423 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
9425 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
9426 Include <limits.h>, and use its INT_MAX to rewrite the
9427 j loop so that it does not overflow 'int'. Problem reported by
9429 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
9430 Play it safe by shifting left by 1 rather than multiplying by 2,
9431 as GCC is less likely to optimize this away when the value
9432 is signed (when it assumes overflow leads to undefined behavior).
9433 Also, don't assume time_t uses two's complement.
9435 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9437 * tests/torture.at (Substitute a 2000-byte string): Avoid using
9438 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
9439 dumps core on it. Report by Tim Rice.

9445 AC_PRESERVE_HELP_ORDER is not used.
9446 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
9447 --with argument, rather than argument with [-.] replaced by
9449 * NEWS: Fix typo in previous change; the news was in the
9452 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
9454 * NEWS: Warnings are now generated by default for unknown
9455 --enable-* and --with-* options.
9456 * doc/autoconf.texi (Option Checking): Renamed from
9457 (Configure Option Checking). Tighten up the wording a bit.
9458 (External Software, Package Options): Cross-reference to Option
9459 Checking, and use this to shorten our section.
9460 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
9461 "$x" to test "x$foo" != x.
9462 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
9463 Don't warn if $enable_option_checking is "no".
9464 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
9465 ac_unrecognized_opts to the empty string.
9466 Don't echo the unrecognized opts, as this might mishandle
9467 backslashes or leading -.
9468 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
9469 usage next to the other --disable-FEATURE options in the
9472 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9474 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
9475 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
9476 Print warning for unrecognized --with and --enable options
9477 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
9478 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
9479 Disable option checking when subdirs are configured.
9480 (AC_OUTPUT): If warnings are enabled, print warning about
9481 unrecognized --with and --enable options at the end of
9482 the configure output (as well as at the beginning).
9483 * doc/autoconf.texi (Option Checking): New node.
9484 Document new option warning functionality.
9486 2006-12-16 Eric Blake <ebb9@byu.net>
9488 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9489 * NEWS: Start news for current version.
9491 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9493 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9494 Define HAVE_GETMNTENT to 1, not to the empty string.
9495 Problem originally reported by Jochen Friedrich in
9496 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9498 This change prompted by a problem report by Andrey Simonenko in
9499 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9500 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9501 object-like macros only, in the traditional portable character
9503 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9504 Warn about attempts to define things that are not identifiers.
9505 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9506 awful hack that AC_DEFINEd macro names containing parentheses.
9508 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9510 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9511 too drastic, even if Texinfo in theory requires it for info mode.
9513 (config.status Invocation): Renamed back from Recreating a
9515 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9516 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9518 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9520 * NEWS: Version 2.61a.
9522 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9523 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9525 * NEWS: Document changes with echo and printf, and the lack
9526 of limits on the total size of multi-line values of substituted
9527 variables, and the AC_FUNC_FSEEKO fix.
9529 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9531 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9532 Writing configure.ac.
9533 (Autoconf Input Layout): Renamed from configure.ac Layout.
9534 (Recreating a Configuration): Renamed from config.status Invocation.
9535 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9536 (acconfig Header): Renamed from acconfig.h.
9537 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9538 (Writing Testsuites): Renamed from Writing testsuite.at.
9539 (Autom4te Cache): Renamed from autom4te.cache.
9541 * BUGS: Remove mention of VPATH problem, since it's now documented
9542 not to be a bug in the Autoconf build procedure itself, but rather
9543 a problem with the proprietary `make' programs.
9545 * doc/autoconf.texi (Build Directories): Add a cross reference
9548 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9549 * doc/standards.texi: Sync from gnulib.
9551 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9552 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9553 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9554 generated automatically.
9556 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9558 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9559 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9560 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9562 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9564 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9565 `CEOF$ac_eof' special marker, the awk script cannot contain a
9566 line matching `^CEOF', so this is not needed any more.
9567 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9568 special marker in the test.
9570 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9572 * tests/tools.at (autom4te preselections): Use `find -newer';
9573 remove one of the sleeps.
9575 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9576 more readable, using ...
9577 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9579 * doc/autoconf.texi (autoheader Invocation): Do not double-
9580 quote the parameter of `AH_BOTTOM' in the example.
9582 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9584 * doc/autoconf.texi (Configuration Headers): Remove the
9585 example with multiple input files.
9586 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9587 multiple input files.
9589 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9592 creating the awk substitution script, handle one input line at a
9593 time, so that the maximum length of a substituted (multi-line)
9594 value is not limited by the size of the sed pattern space.
9595 The trade-off is a slightly repetitive sed script.
9596 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9597 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9598 * tests/torture.at (Substitute a 2000-byte string): Increase the
9599 test with several long lines, they should not be caught by sed
9602 * tests/tools.at (autom4te preselections): New test, to flag
9603 entries missing from autom4te.cfg.
9604 Report by David Byron <dbyron@hheld.com>.
9606 * tests/torture.at (Substitute a 2000-byte string): Actually use
9607 AC_PROG_AWK, so the last change works as intended.
9608 (Substitute and define special characters): Likewise.
9609 (Substitute a newline): Likewise.
9611 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9612 instead of `awk' consistently.
9613 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9614 * tests/torture.at (Torturing config.status): Test both the
9615 result of AC_PROG_AWK and plain awk.
9616 (Substitute a 2000-byte string): Likewise.
9617 (Substitute and define special characters): Likewise.
9618 (Substitute a newline): Likewise.
9620 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9622 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9623 can be assigned to a function pointer. Problem reported by
9624 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9625 part of a patch by Ralf Wildenhues in that same bug report.
9627 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9629 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9630 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9632 2006-12-01 Eric Blake <ebb9@byu.net>
9634 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9635 cross-compiling from cygwin to mingw.
9636 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9637 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9638 to lib/autoconf/c.m4.
9640 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9642 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9643 string for more reliable failure. Wrap the entire test that
9644 causes the broken Solaris printf to dump core, in a subshell,
9645 so the segmentation fault message is reliably suppressed.
9646 Fix shell expansion errors by using /usr/ucb/echo always;
9647 avoid an error on systems without it by another subshell.
9648 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9649 subshell-$as_echo to `as_echo', for better error message.
9651 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9653 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9654 `BASH_SOURCE' contain a newline, set them to empty, as they may
9657 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9659 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9660 years and is too hard to maintain now. The last straw was
9661 reported by Jerker Baeck in
9662 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9663 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9664 * doc/autoconf.texi (Particular Functions): Move
9665 AC_FUNC_SETVBUF_REVERSED from here...
9666 (Obsolete Macros): ... to here. Say that it does nothing now.
9667 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9668 Turn into (almost) a no-op.
9670 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9672 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9673 These macros are obsolescent and new applications shouldn't need them.
9674 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9675 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

9681 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9683 * doc/autoconf.texi (Setting Output Variables): Mention that
9684 @VAR1@VAR2 has unspecified behavior. Problem reported by
9686 * NEWS: Mention this.
9688 * Makefile.am: Put only a single '#' into the copyright notice,
9689 so that it's also present in the output file. Standardize wording
9690 in makefile copyright notices to match GNU coding standards.
9691 * bin/Makefile.am: Likewise.

9704 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9706 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9707 in the sed script that mangles the awk script: delete up to the
9708 first exclamation mark only.
9709 * tests/torture.at (Substitute and define special characters):
9712 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9714 Rewrite config files generation: avoid quadratic growth in
9715 the number of substituted variables by using awk instead of sed
9716 for the bulk of the substitutions.
9717 * NEWS: Mention this.
9718 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9719 forbidden in the output (and thus input) file.
9720 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9721 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9722 generate just one large awk script for substitutions,
9723 eliminating much of the earlier complexity, while adding some
9724 new complexity. Only expand the substitution templates at
9725 configure time, for smaller configure script size. If
9726 _AC_SUBST_FILES are used, test 'awk' for working getline support
9727 at config.status time. If absent, interpolate through the
9728 shell. The awk script was written with much help
9729 from Paolo Bonzini and Paul Eggert.
9730 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9731 (_AC_SED_FRAG_NUM): Likewise.
9732 (_AC_SUBST_CMDS): Renamed from...
9733 (_AC_SED_CMDS): ...this.
9734 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9735 * tests/torture.at (Substitute a 2000-byte string): Also
9736 substitute a line with 1000 words, and a variable with several
9738 (Substitute and define special characters): Test awk special
9739 characters, and put substitution input strings `@foo@' in the
9740 output, to test that no recursion happens; test several other
9741 combinations from Paolo Bonzini.
9743 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9745 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9746 that replaced echo with AS_ECHO where this wasn't necessary.
9747 Problem reportd by Ralf Wildenhues.
9748 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9749 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9750 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9752 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9754 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9756 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9758 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9759 that traditional Awk lacks 3-arg "split". It has it.
9760 Mention that FS must be a single character, and a few other
9761 99-byte limits of traditional Awk.
9762 Mention that if (i in a) doesn't work with traditional Awk.
9764 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9766 * tests/autotest.at (BSx641-newline in command):

9768 (Newline-CODE-BS-newline in command):
9769 (Single-quote-BS-newline in command):
9770 (Single-quote-newline-BS-newline in command):
9771 Use printf '%s\n' instead of echo, for portability to hosts
9772 where echo interprets backslashes. This will break on hosts
9773 that lack printf, but for now let's assume all such hosts
9774 are dead (if not, we should get reports of test failures).
9776 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9778 'echo' has some portability problems, when given a first argument
9779 with a leading '-', or when given any argument containing '\'.
9780 Avoid using 'echo' in these cases.
9781 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9784 * lib/autotest/general.m4 (AT_INIT): Likewise.
9785 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
9786 argument might be unportable.

9805 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9806 * bin/autoconf.as: Redo verbose flag implementation, as the old
9807 scheme wouldn't work with AS_ECHO.
9808 * lib/autotest/general.m4 (AT_INIT): Likewise.
9809 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9810 Don't use ECHO_T, since ECHO_N is now reliable.
9811 * lib/autotest/general.m4 (AT_INIT): Likewise.
9812 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9813 rather than using a here-document to put the script into a file.
9814 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9816 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9817 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9818 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9819 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9820 * lib/autotest/general.m4 (AT_SETUP): Likewise.

9822 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9823 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9824 operand, as AS_ECHO requires. Avoid double file name expansion.
9825 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9826 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9827 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9828 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9829 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9830 Double-quote strings that would otherwise contain M4 comments.
9831 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9833 * configure.ac (AC_INIT): Bump to 2.61a.
9836 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9840 * configure.ac (AC_INIT): Bump to 2.61.
9843 * tests/autotest.at (Macro with backslash in a test title):
9844 Comment out for now, as this tests neither fails nor passes
9845 reliably. Problem reported by Ralf Wildenhues.
9847 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9849 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9850 in previous change, which caused test failures.

9938 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9939 Imported from a similar patch to gnulib by Bruno Haible.
9941 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

9968 ./micro-suite -l and the title in micro-suite.log.
9969 (Backquote in a test title,
9970 Single-quote in a test title,
9971 Double-quote in a test title): Don't expect failure anymore.
9972 (Backslash in a test title): Put a non-whitespace character after the
9973 backslash so that Bourne shells might actually see it as an escape
9975 (Brackets in a test title,

9985 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9986 The visible effect was a stray [] in the testsuite output.

9993 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9995 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9996 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9997 5363) simply issues a warning when dividing by zero at compile
9998 time. Problem reported by Elias Pipping.
10000 2006-10-26 Eric Blake <ebb9@byu.net>
10003 * doc/autoconf.texi (Evaluation Macros): Improve the example to
10004 show effect on macros that expand with commas.

10032 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
10033 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
10034 reported by Nelson H. F. Beebe for Coreutils 6.4.
10036 * tests/tools.at (autoconf --trace: user macros): Remove test
10037 for tracing multiline macros, since m4 1.4.7a uses a different
10038 way to number lines. Problem reported by Ralf Wildenhues.
10040 2006-10-24 Stepan Kasal <kasal@ucw.cz>
10042 * bin/autom4te.in (handle_m4): Do not redirect stdin to
10043 /dev/null since the heuristics for interactive behaviour was

10047 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

10100 looking for special shell characters.

10114 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
10116 (Imported from Automake.)
10117 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
10118 which incorrectly sets the mode of an existing destination
10119 directory. In some cases the unpatched install-sh could do the
10120 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
10121 system. We hope this is rare in practice, but it's clearly worth
10122 fixing. Problem reported by Alex Unleashed in
10123 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
10124 Also, don't bother to check for -m bugs unless we're using -m;
10125 suggested by Stepan Kasal.

10201 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
10202 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
10203 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
10204 Use a better substitute, by inspecting the output of "ls"
10205 rather than just using ":".
10206 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
10207 rather than AS_EXECUTABLE_P, since we needn't worry about
10208 non-regular files here.
10210 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
10211 due to configuration hassles with this. See Tonya Underwood's report

10235 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
10236 comment about ac_cpp_err; it was incorrect, and anyway
10237 ac_cpp_err is being removed below.
10238 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
10239 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
10240 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
10242 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
10243 with werror_flag and conftest.err and so forth. This is more
10244 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
10245 and anyway the user shouldn't normally want to see this gorp logged.
10246 Problem reported by Ralf Wildenhues.
10247 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
10248 empty, not 'no', since the rest of the code uses 'test -z'.

10252 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10253 Use a single call to AC_DO_TOKENS rather than multiple, for
10255 (_AC_LINK_IFELSE): Test that resulting file is executable.
10256 Problem reported by mwoehlke in
10257 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
10259 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
10260 than creating a file to use with test -x; this is much faster.
10262 2006-10-02 Bruno Haible <bruno@clisp.org>
10264 * lib/autom4te.in (Automake-preselections): Add

10274 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
10275 fseeko testing program twice; just use the earlier result.
10276 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
10277 Set cache var to 'unknown' (not 'no') if leaving the macro unset
10278 still doesn't let the program compile.

10282 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.

10786 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
10788 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10789 to a nonexistent file, so that we don't have to worry about
10790 a local site configuration that doesn't use /usr/local.
10791 Problem reported by Keith Marshall in
10792 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10794 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10796 * doc/autoconf.texi: Be more consistent about using @acronym with
10797 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10798 quite right (it talked about "OSF/Tru64", even though the
10799 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10800 and it even mentioned "OSF 4"!) and at this point there's little
10801 reason to talk about OSF any more, since it died in 1994.
10802 (Specific Compiler Characteristics): Simplify example of
10803 negative-size array.
10804 (File Descriptors): Reorder to make the text flow better.
10805 Remove joke about "appreciate the various levels"; I didn't get it.
10806 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10807 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10808 (File Descriptors, Limitations of Usual Tools):
10809 Tone down the advice against renaming or removing open files.
10810 (Limitations of Usual Tools): Add a new section, on 'rm'.
10812 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10814 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10815 -lXt in LIBS, idea from Karsten Hopp; this was due since
10818 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10819 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10820 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10821 (which belong to Xt, not X itself). See Debian bug 327655.
10823 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10825 * configure.ac (AC_INIT): Bump to 2.60a.
10828 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10832 * configure.ac, NEWS: Update.
10834 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10836 * config/texinfo.tex: Sync from upstream.
10838 * bin/autom4te.in (handle_traces): Transform the `@S|@'
10839 quadrigraph correctly in traces.
10841 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10844 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10845 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10847 * doc/autoconf.texi (Changed Directory Variables): New node,
10848 to document the whole `datarootdir' business a bit better.
10850 * tests/torture.at (datarootdir workaround): Extend test.
10851 Prompted by report by Alexandre Julliard.
10853 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10855 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10856 when using default mode of IBM C 6 for AIX. Problem and two-line
10857 fix reported by Larry Jones.
10859 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10861 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10862 about literal '${datarootdir}' if a definition is found in the
10865 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10867 * NEWS: Use "M4" rather than "m4" when appropriate.
10868 Problem reported by Eric Blake.
10869 * doc/autoconf.texi: Likewise.
10870 Use @acronym around BSD, GCC, and GNU when appropriate.
10871 (Why GNU M4): Renamed from "Why GNU m4".
10872 (Redefined M4 Macros): Mention that Posix
10873 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10874 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10877 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10879 * bin/autom4te.in (handle_output): Do not forbid the empty
10881 * tests/tools.at (autoconf: the empty token): New test.
10883 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10885 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10886 calls, so that we do not care whether they are LIFO or FIFO;
10887 in the m4_wrap, do not check which diversion is the topmost
10888 one, just check that the stack is balanced at the end.
10889 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10890 base diversion forever--pop the previous diversion before
10891 opening the new one; consequently, remove the m4_wrap call.
10892 * lib/autotest/general.m4 (AT_INIT): Likewise.
10893 * tests/m4sugar.at: Do not use
10894 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10896 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10897 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10899 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10900 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10901 Rework example of m4wrap token-pasting trouble so that it doesn't
10902 care whether it's LIFO or FIFO.
10903 Fix some "contrary to"s that are awkward in English.
10905 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10907 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10908 to `yes' instead of `int$1_t' if the type is found, for more
10909 consistent configure output (where $1 is the number of bits).
10910 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10911 Suggested by Bruno Haible.
10913 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10914 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10915 with system headers. Report by Bruno Haible.
10917 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10919 * config/config.guess, config/config.sub: Sync from upstream.
10921 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10922 in order to avoid picking up an older installed frozen m4sh.m4f.
10923 Besides an outdated shell startup, this could have been created
10924 by an earlier M4 version with incompatible frozen file format.
10926 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10928 * README: Recommend m4 1.4.4 instead of 1.4.3..
10929 * doc/autoconf.texi: Likewise.
10930 (Special Chars in Names): Say that $(.FOO) is portable, as
10931 suggested by Stepan Kasal.
10932 (Installation Directory Variables, Build Directories):
10933 (Automatic Remaking, Subdirectories, Fortran Compiler):
10934 (Making testsuite Scripts, Defining Directories):
10935 Quote variable usages better.
10936 (Making testsuite Scripts): Add clean-local rule to makefile
10937 snippet, by Eric Blake.
10938 (Installation Directory Variables): Fix table item font.
10939 Reword slightly to clarify. Generalize advice about
10940 not using special characters to include all file-related
10941 vars, not just VPATH.
10942 (Special Chars in Variables): Warn about special characters in
10944 (Assignments): Clarify default-value example as suggested by
10946 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10947 (Special Shell Variables): Note leading ./ or ../, as suggested
10949 (Limitations of Builtins): Under cd, warn about CDPATH.
10950 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10953 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10955 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10956 `@var', for texi2html.
10957 (Systemology): Some more word wrapping, for DVI output.
10958 (autom4te Invocation): The short option for `--melt' is `-M',
10961 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10963 * doc/autoconf.texi: More formatting and English tweaks,
10964 many suggested by Ralf Wildenhues.
10965 Reword to avoid "@code{...}'s" and the like, since it's ugly
10966 with Emacs info mode. discontents -> woes.
10967 Put a few "will"s back. time stamp -> timestamp.
10968 side-effect -> side effect.
10970 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10972 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10973 Warn about $@ not persisting. Problem reported by Julien Danjou in
10974 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10975 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10976 Mention other special chars, too.
10978 2006-06-14 Eric Blake <ebb9@byu.net>
10980 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10982 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10984 * doc/autoconf.texi: Some systematic minor improvements, as
10985 follows. Use "makefile" when talking about makefiles
10986 generally (which might be named "makefile" or "Makefile" or even
10987 "foo.mk"), "Makefile" when talking about a specific makefile
10988 called "Makefile". This unclutters the text from weird quotes
10989 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10990 values" rather than "@var{foo}s" and similar constructs containing
10991 "}s". Use "Make rules" rather than "Makefile rules". Minor
10992 English-language improvements. Change the prefix "sub-" to "sub"
10994 Put blank lines around examples more consistently.
10995 Avoid "rather" and "very" as intensifiers.
10996 Avoid "will" as an auxiliary.
10997 (Limitations of Make): Split this node into....
10998 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10999 (Leading _ in Macro Names, Backslash-Newline-Newline):
11000 (Backslash-Newline Comments, Long Lines in Makefiles):
11001 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
11002 (obj/ and Make, make -k Status, VPATH and Make):
11003 (VPATH and Double-colon, $< in Explicit Rules):
11004 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
11005 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
11006 New nodes, resulting from splitup of Limitations of Make.
11007 All cross-references changed. Raise the top node from
11008 a section to a chapter, and all subnodes accordingly.
11009 Redo the introductory wording to match the new organization.
11010 (Installation Directory Variables): Use an example that is
11011 closer to what Autoconf actually does. Mention that VPATH's
11012 value should not contain metacharacters or white space.
11013 (Fortran Compiler): Fix a VPATH bug in an example.
11014 (Leading _ in Macro Names): Mention that this problem is no longer
11015 of practical concern.
11016 (VPATH and Make): Reword the advice to make it clearer
11017 that Autoconf and Automake support VPATH in non-GNU make, but
11018 many packages have bugs in this area.
11019 ($< in Explicit Rules): Refer to Build Directories rather
11020 than using a (non-VPATH-safe) example.
11021 (Automatic Rule Rewriting): Mention the sort of disaster that
11022 can ensue with Solaris-style rule rewriting with VPATH.
11024 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11026 * doc/install.texi (Compilers and Options): Weaken the
11027 suggestion to use GNU make for VPATH builds.
11029 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
11030 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
11032 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
11033 in regular expression.
11035 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11037 * doc/autoconf.texi (Installation Directory Variables):
11038 Drop extra @samp from `@table @samp' item.
11039 (Limitations of Usual Tools): Comment fix.
11040 Do not nest @samp just to point to other table items.
11041 (Writing testsuite.at) <AT_CHECK>: The second argument to
11042 `@dvar' is already @samp'ed.
11043 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
11044 do not use @var in the second argument.
11046 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
11048 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
11049 $as_shell.exe too. Problem reported by Andreas Buening in
11050 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
11052 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11054 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
11055 `unused variable' compiler warning, for `-Wall -Werror'.
11056 Reported by Jaap Haitsma in
11057 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
11059 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
11061 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
11062 case the compiler dumps core. Problem reported for
11063 OpenServer 5.0.7 by Tim Rice in
11064 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

11068 2006-06-06 Tim Rice <tim@multitalents.net>.
11070 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
11071 "ERROR" only shows up in "make check" output if there is an

11080 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
11082 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
11083 typically overflows on x86 CPUs, even though the C standard
11084 requires otherwise.
11086 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11088 * configure.ac (AC_INIT): Bump to 2.59e.
11091 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11095 * config/texinfo.tex: Sync from upstream.
11097 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
11098 seen, invoke libtoolize with `--ltdl' argument.
11099 * lib/autom4te.in (Autoreconf-preselections): Adjust.
11101 Suggested by Eric Blake.
11103 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
11105 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
11106 reported by Ralf Wildenhues.

11117 2006-06-05 Stepan Kasal <kasal@ucw.cz>
11119 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
11120 message issued by AC_REQUIRE.
11121 * tests/m4sugar.at: Check m4_require's error message.
11122 * tests/base.at: Check AC_REQUIRE's error message.
11123 * tests/local.at (AT_CHECK_M4): New macro, almost identical
11125 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
11127 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
11128 `expout' as the last parameter.
11129 * tests/tools.at: Adapt to the above change.
11131 2006-06-04 Stepan Kasal <kasal@ucw.cz>
11133 * doc/autoconf.texi (Limitations of Usual Tools): Correct
11134 information about race-free implementations of mkdir.
11136 2006-06-04 Eric Blake <ebb9@byu.net>

11143 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
11145 * NEWS: GNU make now recommended for VPATH builds.
11146 Mention that some macros are now documented to be obsolescent.
11147 * doc/autoconf.texi:
11148 Prefer "current" to "modern" to describe
11149 currently-used (albeit perhaps old-fashioned) hosts.
11150 Mention which ancient features no longer need to be worried about.
11151 setgid -> set-group-ID
11152 setuid -> set-user-ID (these are the Posix terms)
11153 Fix some misuses of "only".
11154 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
11155 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
11156 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

11163 Mention that these macros are obsolescent.
11164 (Installation Directory Variables): shall -> should
11165 (File Descriptors): Mention that 0, 1, 2 might get reopened.
11166 Mention that it's now safe to use 3 and 4.
11167 (Limitations of Usual Tools): cp -r is now specified by Posix.
11168 Omit longwinded and obsolescent discussion of cp -f.
11169 Modernize discussion of expr, ls.
11170 (Limitations of Make): Modernize discussion of VPATH builds.
11171 Mention $? as a workaround in some cases.
11172 * doc/install.texi (Basic Installation):
11173 Mention "./configure; make; make install" first. Be more
11174 specific about why this file is generic. Remove unnecessary
11175 parens. Remove misleading "only". Remove obsolete advice
11176 about csh. Don't say "configure" takes awhile; say it
11177 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
11178 and CC=c99 rather than CC=c89, as these are blessed by current
11179 Posix. Recommend GNU make if doing a VPATH build.
11181 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
11183 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for

11187 and Paul Eggert <eggert@cs.ucla.edu>
11189 * doc/autoconf.texi (Here-Documents): Add details about the
11190 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
11191 use "here-documents" instead of "here documents".
11193 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

11204 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
11205 about quoting the case statement, just in case.

11221 argument with leading hyphen. Problem reported by Paul Eggert.
11223 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11225 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
11226 about quoting ac_try: quote all of it, if any of it seems suspicious.
11227 This means we don't have to worry about ${ or sed any more.
11228 Also, double-quote the case statement, to work around misuses via
11229 underquoting as reported by Ralf Wildenhues in
11230 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
11231 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
11232 undocumented and dangerous macro.

11239 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
11240 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
11242 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11244 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
11245 since evidently some packages rely on the old, broken behavior.
11246 Problem reported by Ralf Wildenhues in
11247 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
11248 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
11249 pre-2006-05-26 definitions, but leave in the comments that
11250 these macros are dangerous and should not be used.
11251 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
11252 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
11253 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
11254 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
11255 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
11257 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
11259 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
11260 the use of 'tr', since this is our only use of 'tr'.
11262 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11263 and Paul Eggert <eggert@cs.ucla.edu>
11265 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
11266 Don't assume 'grep' works on long lines, since AIX grep doesn't.
11268 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11270 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
11271 the output file in the `${datarootdir}' test.
11273 2005-05-28 Stepan Kasal <kasal@ucw.cz>
11274 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11276 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
11277 mention of `datarootdir' in the input file(s), but literal
11278 `${datarootdir}' in the output file, and we haven't warned yet,
11279 then warn as well: the user may have (erroneously) used
11280 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
11281 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
11282 * tests/torture.at (datarootdir workaround): Extend this test.
11285 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11286 and Paul Eggert <eggert@cs.ucla.edu>
11288 * doc/autoconf.texi (autoheader Invocation): The first argument to
11289 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
11290 alternatives and clear up the language a bit.
11292 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
11294 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
11295 ac_config_guess, ac_config_sub, ac_configure.
11296 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11297 Fix typo that prevented an unnecessary space from being removed.
11298 Problems reported by Ralf Wildenhues in:
11299 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
11301 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
11303 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
11304 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
11305 Don't use the term "thread-safe" to talk about mkdir race
11306 conditions, since the problem is more a process than a thread
11307 issue. Problem reported by Stepan Kasal in:
11308 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
11309 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
11310 the test for 'install' more closely. Look at MKDIR_P first.
11311 Look in the PATH, and at /opt/sfw/bin.
11312 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
11313 Don't bother to try mkdir -p, since we already check mkdir --version;
11314 just look at the version number. (There's no easy way to check
11315 for race-free implementations.)
11316 * tests/tools.at (autoconf: subdirectories): Adjust to above
11317 changes, since MKDIR_P now might end in "/mkdir -p".
11319 * doc/autoconf.texi (autoheader Invocation): Mention that the
11320 first arg of AC_DEFINE_UNQUOTED must be a literal.
11321 Problem reported by Ben Pfaff in
11322 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
11324 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
11325 * doc/autoconf.texi (Special Chars in Variables): New section.
11326 (Preset Output Variables): Warn about special chars in CPPFLAGS.
11327 (Installation Directory Variables): Quote $(datadir) better.
11328 (Limitations of Builtins): Describe some of eval's trickiness.
11330 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
11331 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
11332 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
11333 in front of every arg, not just trailing args. Quote apostrophes.
11334 (_AC_EVAL_ECHO): New macro.
11335 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
11336 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
11338 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
11339 exposed by quoting of eval argument. Put the command on line line
11341 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
11342 (_AC_PATH_X, AC_PATH_X): Quote more safely.
11343 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
11344 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
11345 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
11346 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
11347 Use eval more safely.
11348 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
11349 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
11351 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
11352 lines, exposed by quoting of eval argument.
11354 2006-05-26 Stepan Kasal <kasal@ucw.cz>
11355 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11357 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
11358 initialization of `ac_cv_exeext', do not override it if it was
11359 already set, unless it was set to `no', for compatibility with
11360 Autoconf-2.13, and comment this.
11361 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
11362 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
11363 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
11364 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
11365 Document that this test may be overridden by setting
11368 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11370 Revert these two patches:
11372 2006-04-06 Eric Blake <ebb9@byu.net>
11373 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
11374 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11377 2006-04-01 Stepan Kasal <kasal@ucw.cz>
11378 Clean up _AC_COMPILER_EXEEXT* macros.
11379 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11380 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
11381 ac_file to the name of the default output file and call
11382 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
11383 initial `rm' of the candidate files...
11384 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11385 the same list in subsequent `rm' calls, and for the temporary
11386 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11387 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11388 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11389 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11390 no longer needed) by libtool. Make it a cache check.
11391 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11392 copied here by mistake.
11393 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
11394 _AC_COMPILER_EXEEXT.
11395 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
11396 _AC_COMPILER_OBJEXT directly.
11397 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11399 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11401 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
11402 Fix description of how the buggy `sed' works.
11404 2006-05-25 Noah Misch <noah@cs.caltech.edu>
11406 Sync from Automake:
11408 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
11409 ENOLCK. Only mention `make -j' when applicable. Only raise
11410 fatal errors when `make -j' is involved. Improve error message.
11412 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11414 * doc/autoconf.texi (Here-Documents): We now know more about
11415 the variable expansion in here documents bug.
11416 Thanks to Tim Rice and Stepan Kasal.
11418 * doc/autoconf.texi (Making testsuite Scripts): Add an example
11419 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
11421 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11423 * tests/autotest.at (Multiline command from M4 expansion):
11424 No failure to be expected if the shell quotes newlines in
11425 commands in the `set -x' output. Report by Tim Rice.
11428 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11430 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
11431 expansion in the here-documents used by config.status, as that
11432 runs afoul of the Korn shell version M-12/28/93d bug described in
11433 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
11434 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
11435 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
11437 2006-05-23 Jim Meyering <jim@meyering.net>
11439 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
11440 Fix typo introduced with 2006-04-02 change. It reversed the sense
11443 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11445 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
11446 ac_dB slightly, to save bytes in the script.
11447 Max out at 50 lines, rather than 96; this is more likely
11448 (though not guaranteed) to avoid obscure 'sed' failures.
11450 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11452 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
11453 `tr -d -' as bad option argument. Work around this by deleting
11454 an unrelated character.
11455 Report by Tim Rice <tim@multitalents.net>.
11457 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
11458 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11459 Stepan Kasal <kasal@ucw.cz>
11461 * doc/autoconf.texi (Particular Programs): Do not promise that
11462 we always prefer the GNU version of the program, and that we
11463 search according to PATH; both rules can have exceptions.
11464 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
11465 AC_PROG_SED. Move descriptions of limitations
11466 to the Limitations of Usual Tools section.
11467 (Limitations of Usual Tools) <sed>: Mention script length
11468 limitations with Solaris /usr/ucb/sed.
11469 <grep>: Fix wording for empty alternative. Mention that -c and
11470 -l should not be combined, and that -E and -F should not be
11473 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11474 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11476 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
11477 limits in Solaris 8 /usr/ucb/sed by testing a long script.
11479 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11481 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11482 AC_DEFINE is now passed to m4_pattern_allow.
11483 * NEWS: Mention that; likewise for AC_SUBST.
11484 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11485 the parameter to m4_pattern_allow.
11486 * tests/tools.at: Add a check for that.
11488 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11490 * lib/autoconf/status.m4: Fix typos.
11492 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11494 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11495 only the files that this macro generates.
11497 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11499 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11500 the HP-UX sed limitation of 99 commands, labels do not count.
11501 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11503 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11505 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11507 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11508 Import the following fix from coreutils:
11510 2006-01-13 Jim Meyering <jim@meyering.net>
11512 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11513 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11514 not double-quote uses of that variable, to accommodate the rare
11515 case in which getmntent is available in none of the libraries
11516 checked. This happens at least on FreeBSD 5.0.
11518 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11520 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11521 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11522 some other programs unwisely rely on these undocumented vars.
11523 But put in warning comments about them.
11524 Problem reported by Ralf Wildenhues in
11525 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11526 * NEWS: Document that these variables are intended to go away.
11528 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11530 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11531 and set the language to C++ (analogous to the equivalent Fortran
11534 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11535 * doc/autoconf.texi (C++ Compiler): Document it.
11536 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11539 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11541 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11542 that caused config.status to generate 100-command sed scripts; the
11543 portable limit is 99.
11545 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11547 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11548 variable `ac_d' instead of `d' to avoid infringing namespace.
11549 Report by Ralf Menzel.
11551 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11553 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11554 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11555 * tests/tools.at (autoconf: subdirectories): New test, taken from
11556 the corresponding problem report by Ralf Wildenhues in:
11557 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11559 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11560 Quote some uses of shell variables if they might suffer unexpected
11561 globbing. This doesn't fix all instances of quoting problems that
11562 I found, just the easy ones that look safe.
11563 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11564 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11565 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
11566 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
11567 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
11568 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
11569 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
11571 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
11572 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
11574 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11576 * bin/autoreconf.in ($help): Reword according to the manual.
11577 Suggested by Olly Betts.
11579 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11580 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11582 * bin/autoreconf.in: Pass the directory argument to
11583 `require_configure_ac'. Fix comment.
11584 * tests/torture.at (Configuring subdirectories): Expose this.
11585 Reported by Olly Betts.
11587 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11589 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11590 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11591 Automake as follows:
11593 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11594 `$configure_in' instead of `configure.in', to preserve
11595 directory component.
11597 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11599 * config/config.guess, config/config.sub, config/texinfo.tex,
11600 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11602 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11604 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11605 test for C99 conformance; (bool) 0.5 is an integer constant
11606 expression, but (bool) -0.5 is not. Problem reported by Fedor
11607 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11609 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11611 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11612 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11613 Warn about obsolete install-sh files. Remove stray sentence
11614 fragment and fix cross reference.
11615 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11616 install -d; this undoes the 2006-05-10 change.
11617 (MKDIR_P): Mark with AN_MAKEVAR.
11618 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11619 that we don't require $INSTALL to be thread-safe. Move comments
11620 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11621 of AC_PROG_INSTALL. Output a message saying that we're checking
11622 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11623 MKDIR_P instead of AC_SUBST.
11624 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11625 Special magic for MKDIR_P, too.
11626 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11628 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11630 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11632 Sync from Automake, as follows:
11634 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11635 * config/install-sh: Initialize IFS, so field splitting isn't
11637 * config/mkinstalldirs: Likewise.
11638 * config/missing: Remove superfluous quotes. Replace all uses of
11639 `[' by `test', for consistency, and for..
11640 * config/missing (sed_minuso, sed_output): New variables.
11641 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11642 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11643 Fixes `missing' to detect `--output' for help2man. Fixes
11644 PR automake/483. Report by Dennis J. Linse.
11645 (autom4te): Document in `missing --help'.

11649 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11650 * config/install-sh: Don't use 'path' to talk about file names,
11651 as per GNU coding standards. Close a race condition reported by Ralf
11652 Wildenhues and Stepan Kasal. There is still a race condition
11653 on hosts that predate Posix 1003.1-1992, but we can't help this.
11654 Don't mishandle weird characters like space on pre-Posix hosts.
11655 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11656 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11657 AC_PROG_MKDIR_P from AS_MKDIR_P.
11658 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11659 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11660 earlier editions are not (including Automake 1.8.3).
11661 Do not suggest mkinstalldirs for thread-safety.
11662 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11663 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11664 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11665 presence of special characters and race conditions.
11666 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11667 in Autoconf's name space.
11669 2006-05-10 Bruno Haible <bruno@clisp.org>
11670 and Paul Eggert <eggert@cs.ucla.edu>
11672 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11673 from Automake with minor changes.
11674 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11676 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11678 * config/install-sh: Update to Automake CVS version, as follows:
11679 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11680 * lib/install-sh: Simplify the expr implementation of dirname.
11681 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11682 * lib/install-sh: Handle --, and diagnose unknown options.
11684 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11686 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11687 `./autom4te' to create `./testsuite', since the `all' target
11688 will ensure its presence, but `installcheck' should not create
11689 the uninstalled wrappers.
11691 * tests/torture.at (Unusual Automake input files): Skip if we
11692 detect automake < 1.8.
11694 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11696 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11697 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11698 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11701 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11703 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11704 munge (multiple) white space and other oddities.
11705 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11706 single quotes in variable assignment.
11707 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11708 and similar failures by adding multiple spaces, tabs, and other
11709 special characters.
11710 Report and different test suggested by Francesco Romani
11711 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11713 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11714 single quotes, we only need to search for single quotes; this
11715 both simplifies the search pattern, and makes us less
11716 susceptible to `echo' variations for arguments not containing
11718 (_AC_ARG_VAR_VALIDATE): Likewise.
11720 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11722 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11723 `$*' and IFS concatenation issue with traditional shells and
11724 bash-2.04. Report by Seanster@Seanster.com.
11726 2006-05-03 Bruno Haible <bruno@clisp.org>
11728 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11729 precisely which Mac OS X versions have the od problem.
11731 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11733 * doc/autoconf.texi: Use @option systematically.
11735 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11736 and Bruno Haible <bruno@clisp.org>
11738 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11740 (Integer Overflow): Mention the special case of integer division
11743 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11745 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11746 traditional shells like the Solaris one that do not use the
11747 first IFS character for assembling `$*'.
11748 Prompted by a related report from autoconf_bug@nro.ca.
11750 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11751 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11753 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11754 Mention more problems with the -e option.
11756 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11759 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11761 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11762 in URLs to improve DVI formatted output (requires texinfo 4.6).
11763 (System Services, Systemology, Shellology): Likewise.
11764 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11767 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11769 (Runtime): Fix macro argument names to match description:
11770 `action-if-found' -> `action-if-true' and similarly.
11771 (Obsolete Macros): Likewise.
11772 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11773 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11774 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11776 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11778 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11781 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
11784 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11786 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
11787 /bin/sh set unsorted output.
11788 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
11789 * tests/local.at: Likewise.
11791 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
11793 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11794 (Integer Overflow, Null Pointers, Buffer Overruns):
11795 (Floating Point Portability, Exiting Portably): New sections.
11796 (Writing Test Programs): Fix some langauge. Recommend exiting
11797 with status 1, not merely nonzero. Clarify exit declaration.
11798 (Run Time): Move C exit status stuff to new Exiting Portably section.
11799 (Systemology): Mention Posix and levenez. Update v7 reference.
11800 (Portable Shell): Mention the Posix shell.
11802 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11804 * bin/autoconf.as (me): Replace by as_me.
11806 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11808 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11809 since as_me isn't set yet.
11811 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11813 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11814 a few minor bugs in this area.
11816 * doc/autoconf.texi (Programming in M4sh): Comment out the
11817 documentation of AS_BASENAME, for now.
11818 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11819 (Limitations of Builtins) <basename>: Do not refer to
11821 * bin/autoconf.as (me): Don't use AS_BASENAME.
11822 (dir): Remove the unused variable.
11823 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11824 AS_DETECT_REQUIRED. All uses changed.
11825 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11827 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
11828 (AS_BASENAME): Use "basename --" to protect against leading "-".
11829 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
11830 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
11831 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
11832 (_AS_DIRNAME_PREPARE): Likewise.
11833 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
11834 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11835 (AS_DIRNAME): Use "dirname --".
11837 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11839 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11840 of "run time" and "run-time" changed to "runtime", for consistency.
11841 * lib/autoconf/fortran.m4: Likewise (in comment).
11842 * lib/autoconf/functions.m4: Likewise.
11843 * lib/autoconf/general.m4: Likewise.
11844 * lib/autoconf/headers.m4: Likewise.
11846 * doc/autoconf.texi (Run Time): Document the exit status situation
11847 with more accuracy and detail.
11849 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11851 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11852 Archive is not officially `GNU' any more. Update URL.
11853 (Defining Directories): Likewise
11854 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11856 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11858 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11859 newline from the `trap' code to finish `config.log'; the NetBSD
11860 /bin/sh resets the exit status after an empty command, as
11861 documented in doc/autoconf.texi.
11862 Reported by Dalibor Topic <robilad@kaffe.org>.
11864 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11866 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11867 Suggested by Bruno Haible.
11869 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11871 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11872 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11873 Instead, just list the shells that we know work.
11874 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11875 changed. Be more cautious about the _cv_ variable.
11876 * tests/tools.at (Syntax of the shell scripts): Check the
11877 _cv_ variable once, at first, to avoid an internal autoconf error
11878 when sh -n does not work.
11880 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11882 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11884 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11886 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11887 use ">&-" since we're only 99.999% sure that this is portable,
11888 and since the MinGW bug is fixed in a different way.
11889 * lib/autotest/general.m4 (AT_INIT): Likewise.
11891 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11893 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11894 before opening config.log, to avoid hitting a bug on MinGW.
11896 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11898 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11899 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11900 This works around a MinGW bug reported by Eric Paire.
11901 Make sure that all writes to the log file append to it,
11902 rather than possibly losing data.
11903 * lib/autotest/general.m4 (AT_INIT): Likewise.
11905 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11907 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11910 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11914 * configure.ac (AC_INIT): Bump to 2.59d.
11916 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11920 * Makefile.maint (news-date-check): Do not require a leading `*'
11921 before the release date in NEWS.
11923 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11924 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11926 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11927 the instantiated file do not contain the string 'datarootdir'
11928 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11929 @mandir@, replace the reference '${datarootdir}' by the value.
11930 * tests/torture.at (datarootdir workaround): New test.
11931 * NEWS: Advertise this temporary fixup.
11932 Based on a patch by Bruno Haible, reported and analyzed by
11933 Paul Eggert and Noah Misch.
11935 2006-04-12 Eric Blake <ebb9@byu.net>
11937 * tests/autotest.at (Debugging a failed test): Fix comment.
11939 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11941 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11942 all the changes since 2006-04-07.
11944 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11946 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11947 succeeded, but `ln -s file dir' failed, take care to remove the
11948 leftover target before the next test, to prevent its spurious
11949 failure; also make sure `ln file dir' works before selecting it.
11950 Thanks to Keith Marshall for pointing this out.
11953 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11954 assignments in `at_debug_args', so that we put them correctly
11955 in the `run' script.
11956 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11957 Reported by Eric Blake.
11959 2006-04-11 Eric Blake <ebb9@byu.net>
11961 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11962 top-level tests after micro-suite has been run. Used in...
11963 (Debugging a successful test, Debugging script and environment),
11964 (Debugging a failed test): ...these new tests. The first of these
11966 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11967 macro, split out from...
11968 (AT_INIT): ...here, so that using -d also generates a run script.
11969 Document that -d inhibits top-level logging.
11970 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11971 inhibits top-level logging; debug scripts are created.
11973 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11975 * tests/autotest.at (Empty test, Empty check): New test to check it.
11977 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11980 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11982 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11983 the files if a problem appears. Make the empty *.at files
11984 read-only, too. Proposed by Ralf Wildenhues.
11986 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11988 * config/Makefile.am: Add comment to force updated Makefile.in.
11990 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11991 space only patch to this file, this patch causes the Makefile.in
11992 files that include freeze.mk to be updated, and thus have a
11993 newer time stamp again, which in turn makes a pristine CVS
11994 checkout have correct time stamps.
11996 * Makefile.maint (cvs-sv): New macro, to be used..
11997 (config.guess-url_prefix, config.sub-url_prefix)
11998 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11999 point to CVS text checkout of Gnulib files.
12000 (copyright-check): Bump current year.
12001 (announcement): Do not hard-wire `./announce-gen'.
12002 (cvs-update): Propagate failures of `cvs' and `move-if-change'
12004 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
12006 (wget_files): Update config.guess, config.sub, texinfo.tex by
12007 `wget-update', now that their URLs work again.
12009 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
12011 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
12012 Problem noted by Paul D. Smith.
12014 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12016 * doc/autoconf.texi: Remove unused words from word list.
12017 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
12018 .x-sc_trailing_space: New files.
12020 * doc/standards.texi: Sync from gnulib.
12022 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
12023 `LIBOBJDIR' as experimental.
12025 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
12026 with a target directory; it's internally implemented as `cp'
12027 anyway, but since Autoconf advertises the possibility to use
12028 a target directory when LN_S is `ln -s', we need to find out.
12029 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
12030 analyzed by Keith Marshall <keith.marshall@total.com>.
12034 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
12036 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
12037 confdefs.h as-is. In general, if it has backslash-newline or the
12038 like, then it doesn't work either to sort or to remove empty
12041 2006-04-09 Stepan Kasal <kasal@ucw.cz>
12043 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
12045 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
12047 * lib/autom4te.in (Automake-preselections): Preselect
12050 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
12052 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
12053 apostrophe within a single-quoted string, as this is the usual
12054 tradition and is easier to read than '"'"'. Don't rely on the
12055 shell treating "$/" like '$/'. Use a more-consistent indenting
12056 style for the trap.
12058 2006-04-09 Eric Blake <ebb9@byu.net>
12060 * tests/autotest.at (Backquote command substitution),
12061 (Multiline backquote command substitution): Remove mistaken
12062 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
12064 (Parenthetical command substitution, Multiline parenthetical
12065 command substitution): here.
12067 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
12069 Import macros from gnulib (often changing their name).
12071 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
12072 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
12073 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
12074 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
12075 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
12076 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
12077 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
12078 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
12079 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
12080 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
12081 The manual mentions Gnulib more prominently.
12082 * doc/autoconf.texi (Gnulib): New node.
12083 (Pointers): Add Gnulib URL.
12084 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
12085 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
12087 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
12088 suggest a #define rather than a typedef for _Bool, and mention
12089 Gnulib rather than trying to substitute stdbool code.
12090 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
12091 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
12092 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
12093 AC_STRUCT_DIRENT_D_TYPE.
12094 (Particular Types): Mention stdint.h and inttypes.h as standard
12096 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
12097 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,

12151 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
12152 * lib/autotest/general.m4 (AT_INIT): No need to give three

12200 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
12201 whether `set' quotes correctly: redirect stderr of the tested
12202 `set', and use a subshell, for Ultrix; use `sed' instead of
12203 `grep' for zsh `set' which may write binary output; match only
12204 at the beginning of a line, to avoid false positives.
12205 In order to avoid false positives by unrelated variables with
12206 multiline content, put the dump algorithm in a subshell and
12207 unset all variables containing newlines (except some which are
12208 special to the shell). Warn about cache variables that are

12255 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
12256 (AC_CONFIG_COMMANDS): Do not do so here.
12257 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
12258 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

12265 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

12324 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
12325 Use 'comm' rather than N instances of grep; this also fixes a bug

12421 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
12422 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
12423 no longer needed) by libtool. Make it a cache check.

12425 copied here by mistake.

13198 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
13199 AC_LANG_PROGRAM, fixing a typo. Don't give details about
13200 the inner workings of AC_LANG_FUNC_LINK_TRY.
13201 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
13202 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
13203 by the function rather than ignoring it.
13204 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
13205 comparing its address. Intel's interprocedural optimization was
13206 outsmarting the old heuristic. Problem reported by

13218 2005-10-04 Stepan Kasal <kasal@ucw.cz>
13220 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable

13224 Stepan Kasal <kasal@ucw.cz>
13226 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
13227 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
13228 make its content writable before removing it. Remove an errorneous
13229 comment from the end, where the logs of the failed tests are copied
13230 to the main log file.
13232 2005-09-27 Stepan Kasal <kasal@ucw.cz>
13234 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
13235 in case the computer is too quick. Double quote the configure.ac
13238 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
13239 problems if the testsuite were running too fast.
13241 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
13243 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
13244 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
13245 (which belong to Xt, not X itself). See Debian bug 327655.
13246 * NEWS: Mention this.
13248 2005-09-07 Stepan Kasal <kasal@ucw.cz>
13250 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
13252 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
13254 * config/move-if-change: Don't output "$2 is unchanged";
13255 suggested by Ben Elliston. Handle weird characters correctly.
13257 2005-09-06 Stepan Kasal <kasal@ucw.cz>
13259 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
13260 calls, so that the final expansion of this macro is shorter.
13261 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
13262 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
13263 the cleanup there. Use AS_VAR_* macros, to be more general.
13264 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
13266 * lib/autoconf/general.m4: Use AS_IF where appropriate.
13268 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

13283 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13284 The previous patch didn't work, so try a better one.
13286 2005-08-26 Stepan Kasal <kasal@ucw.cz>
13288 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
13289 in the example. Reported by Bruno Haible.
13290 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
13291 "if $undefined_var;" succeeds with my shell.
13293 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
13294 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
13295 but change the m4_divert_text to m4_divert_once.
13297 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
13299 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13300 Work around bug in Solaris /usr/xpg4/bin/awk.
13301 The bug is present in at least Solaris 8 through 10.
13303 2005-08-24 Stepan Kasal <kasal@ucw.cz>
13305 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
13306 some evil values and relying on the fact that $* concatenates the
13307 parameters by the first character from IFS.
13309 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
13310 Stepan Kasal <kasal@ucw.cz>
13312 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
13313 first header appears, define AH_HEADER.
13314 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
13315 Update limitations about when to call AC_CONFIG_HEADERS.
13316 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
13317 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
13318 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
13319 ``Configuration Actions''; fix their index entries.
13321 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
13322 options correctly. Process N-M as M-N if M is smaller than N.
13323 Process ranges correctly so that N-N will run only N.
13324 Sort and uniquify the tests that will be run. If there is more
13325 than one test, reinsert the banners for the tests.
13326 * tests/autotest.at (Keywords): Unmark XFAIL.
13328 2005-08-23 Stepan Kasal <kasal@ucw.cz>
13330 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
13331 before passing the macro name to AH_TEMPLATE.
13333 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
13334 now opens log after option processing; in particular, --version
13335 and --help do not touch config.log.

13348 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
13351 * doc/autoconf.texi (Defining Symbols, Changed Results):
13352 Prepend to LIBS, not append, in examples.
13354 2005-08-16 Stepan Kasal <kasal@ucw.cz>
13356 When building in place, set srcdir="."; suggested by Tim Van Holder.
13358 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
13359 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
13360 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
13361 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
13362 does not mean "no --srcdir option".
13364 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13366 * tests/autoscan.at (autoscan): New file.
13367 * tests/suite.at: Use it.
13368 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
13369 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
13371 * tests/autotest.at (Keywords): Test keywords combinations.
13373 2005-08-12 Stepan Kasal <kasal@ucw.cz>
13375 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
13376 add "2>&1"; gzip 1.2.4 prints help on stderr.
13378 2005-07-27 Stepan Kasal <kasal@ucw.cz>
13380 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
13381 was pushdef'ed twice while popped only once. Push it only once.
13382 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
13384 2005-07-26 Stepan Kasal <kasal@ucw.cz>
13386 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

13391 * Makefile.maint: Update from Bison.
13393 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
13394 "<tab>" in comment, so that the point is understandable.
13396 2005-07-25 Stepan Kasal <kasal@ucw.cz>
13398 Rewrite substantial part of lib/autoconf/status.m4.
13399 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
13400 and CONFIG_COMMANDS are not processed in four separate loops.
13401 Instead, there is one main loop. This alows that the common code
13402 is expanded only once, thus config.status (and configure) is smaller.
13404 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
13405 the AC_LIST_FILES and cousins macros are no longer used.
13407 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
13408 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
13409 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
13410 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
13411 contain the initialization, nor the for loop, nor the associated
13412 commands; all these go to ...
13413 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
13414 _AC_OUTPUT_CONFIG_STATUS.
13415 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
13416 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
13417 (_AC_OUTPUT_FILE): The creation of the sed script ...
13418 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
13419 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
13420 _AC_OUTPUT_MAIN_LOOP.
13421 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
13422 _AC_CONFIG_COMMANDS): Use ...
13423 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
13424 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
13425 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
13426 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
13427 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
13428 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
13430 (_AC_CONFIG_UNIQUE): Update.
13431 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
13432 Replaced by this ...
13433 (_AC_LIST_TAGS): ... new common macro.
13434 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
13435 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
13436 (_AC_LIST_TAG_COMMANDS): ... new common macro.
13437 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
13438 this didn't belong to the `config commands' section.
13439 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
13440 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
13441 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
13442 to the `config commands' section either.
13443 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
13444 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
13446 ... and many changes to the comments nearby.

13451 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
13452 (#define header templates): The comment at the top of the generated
13453 header now includes the name(s) of the source file(s).
13455 Several unrelated small changes:
13457 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
13458 parameter to AC_DIAGNOSE.
13459 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
13460 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
13461 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
13462 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
13463 with AU::AC_OUTPUT.
13464 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
13465 in AC_OUTPUT doesn't double-quote it either.
13466 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the

13487 ac_cv_build_alias to ac_build_alias.
13488 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
13490 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
13491 change eliminates it. Problem reported by Alexandre Duret-Lutz.
13492 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
13493 (AC_ARG_VAR): ... here.
13494 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13497 Keep a list of all precious variables and process them with one simple
13498 for loop, instead of expanding all commands, or, OTOH, complicated
13499 processing of output of "set".

13507 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13508 its value to shell variable ac_precious_vars and call
13509 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
13510 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
13511 _AC_ARG_VAR_VALIDATE.

13532 They are generated by the Tru64 v5.1B shell.
13534 2005-07-05 Stepan Kasal <kasal@ucw.cz>
13536 Fix my changes from 2005-07-01; reported by Noah Misch.
13537 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
13538 description, the macro now accepts only a single tag.
13539 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
13541 Fix cases when the varsions of Autoconf and Autotest don't match.
13542 Reported by Noah Misch.
13543 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
13544 at_top_builddir, for compatibility with older autotest.
13545 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix

13551 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
13552 Problem reported by Patrick Welche.

13556 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13557 sed substitution command, so that we allow | in program prefixes
13558 and program suffixes. (& is a problem anyway; we're not fixing
13560 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
13561 configure_input, top_builddir, srcdir, etc.
13562 * lib/autotest/general.m4 (AT_INIT): Likewise, for

13565 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
13567 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13568 for loop over config.site files using `set', to allow
13569 directory names containing IFS characters.
13571 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13573 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13574 directories with weird names. Apparently some people like living
13575 on the edge. However, improve the test that "pwd" actually does
13576 report a name for the working directory.

13595 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13596 document to output the default config_* lists to config.status.
13597 Don't recognize option --file, if the functionality is not there.
13598 Likewise for --header; moreover, recognize --he and --h as shortcuts
13599 for --help in that case.
13601 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13602 matches the order of execution. No code changed.

13621 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
13623 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13624 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13625 (AC_SUBST): Call it.
13626 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13627 the directory specific variables; but don't call it for configure_input.
13629 2005-06-28 Derek Price <derek@ximbiot.com>
13631 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13634 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13636 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13637 directory have inherent problems with special characters like spaces,
13638 due to limitations in Make syntax. Problem reported by Alexandre
13640 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13641 Also, fix Tru64 porting problem with shell patterns,

13653 from Justace Clutter.
13654 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13655 variable into diagnostic. Make the diagnostic an error, not a warning,
13656 because we really don't support spaces and suchlike in dir names.
13657 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13658 Don't worry about backslashes in srcdir; it can't happen now.

13660 Simplify ac_optarg handling.
13661 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

13669 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13671 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13672 that '\|' is not allowed in BREs; recommend using newline separated
13673 list of patterns instead of multiple -e options.
13675 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13677 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13683 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13685 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13686 b, t, r, w commands require single space, while : cannot have any.
13687 (Special Shell Variables): Fix sed code this in the example.
13688 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13689 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13691 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13692 expand to the empty list. Don't use two pairs of m4_changequote,
13693 it's not necessary.
13695 2005-06-20 Derek Price <derek@ximbiot.com>
13697 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13699 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13701 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13702 * doc/autoconf.texi:
13703 Don't mention Solaris versions so much, if a
13704 problem is common to all extant versions of Solaris. Say "SunOS
13705 4" instead of "SunOS" for SunOS 4.
13706 (awk): Mention more of the limitations of traditional Awk.
13707 (cat): Don't talk about cat -v.
13709 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
13711 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
13712 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

13714 to be compatible with glibc strverscmp.
13715 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13717 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

13720 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13721 Use shell builtins rather than 'expr', to work around expr bug.
13723 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13725 * doc/autoconf.texi: "filesystem" -> "file system".
13726 "behaviour" -> "behavior".
13727 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13728 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13730 * lib/m4sugar/m4sh.m4: Likewise.
13731 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13732 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

13735 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13736 to update the man page. That way, we don't have to check in new
13737 man pages every month.
13739 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13740 quotes and backslashes. Patch from Derek Price.

13749 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13750 -u, since it outputs chatter if the input files are the same.
13751 Problem reported by Ralf Menzel.
13753 2005-06-08 Derek Price <derek@ximbiot.com>
13755 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13756 renaming them since they are about to be redefined anyhow.
13758 2005-06-08 Derek Price <derek@ximbiot.com>
13760 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13761 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13762 Move m4_undefine to alphabetical order.
13764 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13766 * README: Recommend GNU M4 1.4.3 or later.
13767 * doc/autoconf.texi (Introduction): Likewise.
13768 Reword to avoid some formatting glitches.
13769 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13770 Clarify explanation of HP compiler bug.
13771 Redo example output tp match current CVS snapshot.
13772 Use @example.org in email addresses when the examples
13773 might get inadvertently cut-and-pasted into user code.
13774 Remove example of autom4te usage that doesn't seem to work now.
13775 Use modern AC_INIT (except when the example is meant to be
13776 shown with Autoconf 2.13).
13777 Update ksh info for Solaris 9 and later.
13779 Modernize description of Automake versions a bit.
13780 Don't claim a future version of Autoconf is near.

13786 follows its own advice about quoting better.
13787 Reword to avoid some formatting glitches.
13788 * doc/installt.exi: Reword to avoid some formatting glitches.
13790 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13791 Tru64 ksh pattern matching bug. Reported against Libtool by
13792 Albert Chin <libtool@mlists.thewrittenword.com> and
13793 Nicolas Joly <njoly@pasteur.fr>.
13795 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13797 m4_cdr of one-member list was [[]] (one-member list containing an
13798 empty string) instead of [] (an empty list. Callers were skewed to
13799 match this misbehaviour. As a consequence of this:
13800 - m4_foreach([x], [], [foo]) expanded to `foo', while
13801 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13802 This bug has been fixed:
13804 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13805 expand to an empty string; print error msg if called without
13807 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13808 misbehaviour; handle [] and [[]] correctly.
13810 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13812 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13813 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13814 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13816 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13818 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13819 swallow records with more than 99 fields.
13820 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13821 parse the long line.
13823 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13825 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13826 swallow literals longer than 399. Reported by Ralf Wildenhues.
13827 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13828 to workaround this limitation.
13830 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13832 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13833 to gfortran, and make these the first two compiler names
13834 checked (following the general autoconf preference for gcc).
13836 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13838 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13839 (DISTCLEANFILES): Remove $(check_SCRIPTS).

13844 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13845 expression of unbounded size when processing the --list
13846 option. This runs afoul of a limit of 399 bytes per regular
13847 expression on AIX. Problem reported by Ralf Wildenhues.

13856 Reword description of line replacement.
13858 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13860 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13861 now contain newlines, and substituted files must be referenced on
13862 a line alone; the sed scripts to substitute them are now very
13864 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13865 commands can be put in a sed script portably.
13866 * doc/autoconf.texi (Setting Output Variables): Document above
13867 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

13874 From Ralf Menzel (trivial change).
13876 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13878 * tests/local.at: Don't attempt to check for negated character
13879 classes in shell scripts. The test was too brittle.
13881 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13883 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13884 * doc/autoconf.texi (Limitations of Builtins): Document this
13887 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13889 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13890 common code; used in many places in the tree.
13891 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13892 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13894 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13896 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13897 messages when ac_unique_file is not found.
13898 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13899 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13900 commands, for consistency with AC_MSG_ERROR and such.
13902 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13904 * bin/Makefile.am: Merge the two rules for creating scripts.
13906 2005-05-23 Stepan Kasal <kasal@ucw.cz>
13908 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
13909 obsolete; it was never documented.
13910 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13912 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13914 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13915 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13916 (ac_top_builddir): ... this ...
13917 (ac_top_build_prefix): ... to this; the old name is also kept, for
13918 backward compatibility.
13919 (ac_top_builddir_sub): New variable, without the trailing slash,
13921 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13922 * doc/autoconf.texi (Configuration Actions): Rename
13923 ac_top_builddir to ac_top_build_prefix.
13924 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
13925 at_top_builddir to at_top_build_prefix.
13926 * lib/autotest/general.m4 (AT_INIT): Likewise.
13928 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13930 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
13933 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13935 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13936 argument to m4_foreach. I guess it was necessary in the past,
13937 but I think it's a no-op now.
13939 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13941 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13942 ``cat <<_ACEOF'' commands to one.
13943 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13944 * lib/autoconf/status.m4: On various places, use expr instead of
13946 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13947 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13948 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13950 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13951 the wrong patterns between ``case'' and ``esac.'' The previous
13952 code had false positives.
13954 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13956 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13999 2005-05-13 Stepan Kasal <kasal@ucw.cz>
14001 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
14003 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
14004 enough arguments, similarly as in m4_bpatsubsts.
14006 2005-05-12 Stepan Kasal <kasal@ucw.cz>
14008 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
14011 2005-05-11 Stepan Kasal <kasal@ucw.cz>
14013 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
14014 for absolute directory names in one loop.
14015 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
14016 abbreviations of --version and --debug.
14018 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
14020 * doc/autoconf.texi (Autoconf Language): Be more precise about
14021 quoting rules. Problems noted by Stepan Kasal.
14022 Also, throughout this document, be more careful about white space.
14023 "blank", "white space", and "space" all have different meanings
14024 and we should be careful to say what we mean.
14026 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
14028 Fix C++ related problems reported by Werner Lemberg.
14029 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
14030 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
14031 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
14032 avoid problems with C++ and throw.
14033 * tests/compile.at: .cpp, not .cc.
14035 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
14037 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14039 * doc/autoconf.texi (Generic Functions): Typos.
14041 2005-05-02 Gary V. Vaughan <gary@gnu.org>
14043 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
14044 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
14045 set by latest automake.
14047 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
14049 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
14050 outputs 0 on GNU/Linux these days.
14052 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
14054 * doc/autoconf.texi (Autoconf Language): Add more description
14055 about quoting heuristics.
14056 (Limitations of Builtins): Describe "set -" problems.
14058 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14060 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
14063 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
14064 by AC_DEFINE; it was a mistake.
14065 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
14067 2005-04-25 Stepan Kasal <kasal@ucw.cz>
14069 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
14071 2005-04-22 Stepan Kasal <kasal@ucw.cz>
14073 * doc/autoconf.texi (External Software): Quadrigraphs are not
14074 processed correctly in AS_HELP_STRING; avoid this in the examples.
14075 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
14076 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
14077 comment and reduce m4_default([foo], []) to [foo].
14078 (m4_strip): Update the explanation.
14080 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
14082 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
14083 Remove core.conftest.* too; it's generated by Tru64 5.1.
14084 Problem reported by Jennis Pruett.
14085 * lib/autoconf/functions.m4
14086 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
14087 Don't bother to remove core files; AC_RUN_IFELSE should do that
14090 2005-04-19 Stepan Kasal <kasal@ucw.cz>
14092 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
14094 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
14096 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
14097 Report from Horst Wente.
14099 2005-04-15 Stepan Kasal <kasal@ucw.cz>
14101 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
14104 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
14106 * doc/autoconf.texi (External Software, Package Options): Add
14107 examples showing how to implement --with-* and --enable-* options.
14109 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
14111 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
14112 as well as configure.in. Problem reported by Gregorio Guidi.
14114 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
14116 * doc/autoconf.texi (Particular Functions): Use gnulib's current
14117 pattern for alloca snippet.
14119 2005-04-04 Stepan Kasal <kasal@ucw.cz>
14121 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
14123 2005-04-01 Stepan Kasal <kasal@ucw.cz>
14125 * doc/autoconf.texi (Generic Programs): Fix a typo.
14127 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
14129 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
14130 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
14132 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14134 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
14135 Merge `-z option' as well for the benefit of Solaris link flags. Pass
14136 whole-archive (-zallextract, -zdefaultextract) options in the hope of
14137 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
14138 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
14140 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
14142 * NEWS: The configure command now warns you if you attempt to use
14143 a directory whose name contains a special character like space,
14145 * doc/autoconf.texi (Installation Directory Variables): Allow
14146 "," in file names. Do not use \@; it's not a portable regexp.
14147 * bin/Makefile.am (edit): Likewise.
14148 * lib/Makefile.am (edit): Likewise.
14149 * tests/Makefile.am (edit): Likewise.
14150 * tests/semantics.at: Likewise.
14151 * tests/torture.at: Likewise.
14152 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
14153 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
14154 * doc/autoconf.texi (File System Conventions): Warn about
14155 unportable file names.
14156 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
14158 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
14159 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
14160 ac_pwd, and quote srcdir.
14161 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
14163 * doc/autoconf.texi: Fix some systematic formatting problems.
14164 ".)" needs a following @: if not at the end of a sentence, and
14165 similarly for "!)". "etc." should be preceded by a comma.
14166 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
14168 2005-03-22 Bruno Haible <bruno@clisp.org>
14170 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
14171 argument is often called 'build-aux'.
14173 2005-03-07 Stepan Kasal <kasal@ucw.cz>
14175 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
14176 macro AC_TRY_LINK is obsolete.
14177 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
14180 2005-02-24 Stepan Kasal <kasal@ucw.cz>
14182 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
14183 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
14184 from a Common Lisp's `cl'.
14185 (AC_PROG_CXX): Behave according to the documentation: don't
14186 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
14187 make the variable CCC precious; use `cl.exe', not `cl'.
14189 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
14190 Alexandre Duret-Lutz <adl@gnu.org>
14192 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
14193 /dev/null, as "configure" shouldn't read stdin, and this insulates
14194 us from problems (e.g., when testing for "cl"). Also, do this
14195 redirection before invoking "hostname" or "uname", and keep the
14196 original input stream available via...
14197 (AS_ORIGINAL_STDIN_FD): ... this new macro.
14198 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
14199 bother with "</dev/null" since it's now done at the top of
14201 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
14202 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
14203 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
14204 * doc/autoconf.texi (File Descriptor Macros): New section.
14205 (Printing Messages): Mention it.
14206 * tests/base.at (Input/Output): New test.
14208 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
14210 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
14211 newline if neither \c nor -n work, as that would output two
14212 newlines. Prefer -n to \c. Reported by Stepan Kasal.
14214 2005-02-12 Stepan Kasal <kasal@ucw.cz>
14216 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
14217 This causes that any required macros inside will get before the if.
14218 * doc/autoconf.texi (autom4te.cache): A typo.
14220 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
14222 Undo previous change, except keep the change to
14223 lib/autoconf/programs.m4 that replaced grep with shell
14224 pattern-matching. This is because net-snmp configure reads stdin.
14225 Reported by Noah Misch.
14227 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
14229 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
14230 from /dev/null, as "configure" shouldn't read stdin, and this
14231 insulates us from problems (e.g., when testing for "cl").
14232 Suggested by Alexandre Duret-Lutz. Also, do this redirection
14233 before invoking "hostname" or "uname".
14234 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14235 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
14236 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
14237 "</dev/null" since it's now done at the top of 'configure'.
14238 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
14239 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
14240 Also, replace grep with shell pattern-matching, to save a process.
14242 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
14244 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14245 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
14246 avoid thinking that Allegro Common Lisp's "cl" command is a C++
14249 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
14251 * doc/autoconf.texi (Limitations of Usual Tools): Document that
14252 grep -q isn't portable. Improve grep -s explanation.
14253 Problem reported by Dan Manthey.
14255 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
14257 * doc/autoconf.texi (Special Shell Variables): Clarify
14258 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
14260 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
14262 * doc/autoconf.texi: Use @acronym for DJGPP.
14263 Fix some @code's that should have been @env's, and vice versa.
14264 Sort environment variable names.
14265 Mention that shells no longer inherit IFS.
14266 Don't recommend PATH_SEPARATOR=';' so strongly.
14267 Mention that $RANDOM might expand to the empty string.
14268 "symlink" and "soft link" -> "symbolic link".
14269 Improve mktemp description (reported by Bruno Haible).
14271 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
14273 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
14274 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
14276 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
14279 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
14281 * NEWS: Mention AT_COPYRIGHT.
14283 * tests/local.at (AT_CMP): Use diff directly on input files rather
14286 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
14287 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
14289 2005-02-04 Noah Misch <noah@cs.caltech.edu>
14290 and Paul Eggert <eggert@cs.ucla.edu>
14292 * tests/autotest.at (Empty test suite): New test.
14293 * tests/torture.at (Substitute and define special characters)
14294 (Substitute a 2000-byte string, Define to a 2000-byte string)
14295 (Substitute a newline, Define a newline): New tests.
14297 2005-02-04 Noah Misch <noah@cs.caltech.edu>
14299 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
14300 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
14301 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
14302 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
14303 (Standard regular expressions): New test.
14304 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
14305 excess test name quoting.
14306 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
14307 CPPFLAGS to `configure' instead of setting it in `configure'.
14309 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
14310 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

14408 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
14409 Update the long comment explaining it.
14411 m4_require no longer writes an ``is required by'' line to the
14412 execution stack. It contains only one bit of non-redundant
14413 information: that the macro was required, not called. And even
14414 this bit is useless in most situations: have you ever met a macro
14415 which both calls and requires the same macro?
14417 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
14418 (_m4_defun_pro_outer): ... only via this macro, for the outermost

14425 (_m4_require_call): Use it.
14426 * tests/m4sugar.at (m4_require): Expect output without the
14427 ``is required by'' messages.
14429 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

14463 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
14465 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
14466 Warn about newline stripping in `` and $(). Update Solaris
14468 (Limitations of Builtins): Use expr "X...", not expr "x...", as

14520 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
14522 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
14523 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
14524 stored in _m4_divert_diversion or _m4_divert_dump.
14525 (m4_divert_pop): When the parameter is given, compare the symbolic
14526 name with the last diversion pushed on the stack. Previously, the
14527 current diversion was compared with the numeric value of the
14528 diversion given as the parameter.
14529 (m4_require): If the macro hasn't been expanded yet, call ...
14530 (_m4_require_call): this new macro.

14563 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

14793 the output. Replace each $as_me with a @wrap_program@.
14794 * tests/wrapper.in: Delete it; we always build it.

14809 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
14811 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
14812 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
14813 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
14814 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
14816 2004-12-07 Stepan Kasal <kasal@ucw.cz>
14818 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

14833 with exactly one parameter.
14835 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
14837 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14838 "char c = '\200';" rather than "char c = 0x80;" as the
14839 latter doesn't conform to the strict C standard due to
14840 overflow on signed char hosts.
14842 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
14843 to -qlanglvl=ansi. We don't want to disable extensions.

14949 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
14951 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

14954 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
14956 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14957 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14958 (trivial change). Problem and patch reported by Andrew Church in:
14959 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
14961 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

14991 Remove ansi2knr.c; nobody uses it.
14992 (ansi2knr.c-url_prefix): Remove.
14993 (cvs-update): Fix test for failure. I don't know why it ever
14996 * doc/autoconf.texi: Update URLs, some of which went stale.
14997 Use @uref rather than @href.
14999 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
15000 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
15002 * config/config.guess, config/config.sub, config/elisp-comp,

15014 Use "file name" rather than "filename" or "path",
15015 to be consistent with the terminology of the GNU coding standards.
15017 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
15019 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
15020 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
15021 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
15022 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
15024 More fixes to support spaces in the name of the build directory.
15025 This isn't a complete fix but it's an improvement.
15027 * bin/autoconf.as (autom4te_options): New var.
15028 Use it instead of appending to AUTOM4TE, so that we can allow
15029 spaces in the build directory's absolute name.
15030 * bin/autoheader.in ($autoconf): Allow spaces in file names.
15031 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
15032 AT_CHECK_NOESCAPE): Likewise.

15044 * doc/autoconf.texi (Function Portability): Document isinf and
15045 and isnan. From a suggestion by Kevin Ryde.
15047 * lib/Autom4te/General.pm (END): Return correct exit status even
15048 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
15050 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
15052 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
15053 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
15054 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
15056 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
15058 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.

15065 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
15067 * lib/autom4te.in (Automake-preselections): Preselect
15068 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
15071 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
15073 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
15075 * doc/autoconf.texi (Shellology): Mention BIN_SH.
15076 Document problem with "`""`" in pdksh POSIX mode.
15078 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
15080 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
15081 with pdksh, too. Problem reported by Patrick Welche via
15083 * doc/autoconf.texi (Shellology): Note that set -o posix is
15084 useful for pkdsh, too.
15086 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
15088 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
15089 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
15090 Don't fail if ENV or BASH_ENV is readonly.
15091 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
15092 etc. are read only. Problem reported by Ludovic Courtes.
15094 2004-06-23 Noah Misch <noah@cs.caltech.edu>
15096 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
15097 zsh, disable GLOB_SUBST to avoid backslash handling problems.
15100 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
15102 * doc/autoconf.texi (File System Conventions): Warn about
15103 names like "aux". Problem reported by Eric Blake.
15105 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
15106 by zero instead of array size, so that we can use any arithmetic
15107 constant expression (instead of requiring an integer constant
15108 expression). This allows us to test expressions like DBL_MAX <
15109 LDBL_MAX, which didn't conform to the C standard using the old
15111 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
15112 now that we can do floating-point tests at compile time.
15114 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
15116 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
15117 and LDBL_EPSILON, as the resulting expression isn't an
15118 integer constant expression and violates the C standard.
15119 Problem reported by Nelson H. F. Beebe. Also, check
15120 for "L" suffix, and check that long double doesn't have
15121 worse range or precision than double, that mixed-mode
15122 arithmetic doesn't generate a diagnostic, that double
15123 constants fit in long double.
15125 2004-06-03 Kevin Ryde <user42@zip.com.au>
15127 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
15128 malloc(0) and realloc(NULL,size).
15130 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
15133 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
15135 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
15136 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
15139 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
15141 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
15142 can be rewritten using if-then-else. Suggested by Bruno Haible.
15144 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
15146 * doc/autoconf.texi (testsuite Scripts): Fix typo.
15147 Problem reported by Stepan Kasal.
15149 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
15151 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
15152 change). Patch reported by Ralf Wildenhues in
15153 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
15155 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
15156 function F exists if the compiler and linker let you compile an
15157 expression like (F != 0). Recent versions of GCC optimize away
15158 the reference to F in that case, since every function address must
15159 be nonzero, so the link succeeds even if F does not exist.
15160 Problem reported by Manu in
15161 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
15163 * doc/autoconf.texi (Systemology): Standardize on the spelling of
15164 "Unix". Many uses changed.
15165 (Limitations of Builtins): Explain better why the ! command isn't
15168 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
15170 * lib/autom4te.in (Automake-preselections): Preselect
15171 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
15173 2004-05-19 Kevin Ryde <user42@zip.com.au>
15175 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
15176 referencing AC_FUNC_STRERROR_R.
15178 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
15179 note pessimistic assumption when cross compiling.
15181 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
15183 * doc/autoconf.texi (Limitations of Make): Note that BSD make
15184 (until 2004) invoked subcommands with sh -e, contra POSIX.
15185 Reported by Kevin Ryde.
15187 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
15189 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
15190 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
15191 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
15192 `test -f " /usr/bin/grep"', which _always_ failed.
15193 (AC_PROG_SED): Ditto bogus PATH fix.
15194 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
15195 requires that grep correctly supports _multiple_ `-e' options, rather
15196 than stating only that grep should accept `-e'.
15198 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
15200 Port to C99, which requires that 'exit' be declared.
15202 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
15203 to ensure that stdlib.h is included.
15204 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
15205 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
15206 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
15207 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
15208 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
15209 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
15210 when using 'exit' in a test; C99 requires that 'exit' be declared.
15212 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
15214 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
15215 now prefers 'grep' implementations that accept -e.
15216 (Limitations of Usual Tools): Describe problems of traditional
15217 egrep and fgrep with long input lines, and of traditional grep
15219 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
15220 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
15221 All callers changed. Append /usr/xpg4/bin to the PATH, for
15223 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
15224 the user with complaints about multiple -e options.
15225 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
15226 Define it with AC_PROG_GREP.
15227 * configure.ac (AC_PROG_GREP): Add.
15228 * lib/freeze.mk (GREP): New macro.
15230 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
15232 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
15233 a possible candidate only after all others fail, rather than
15234 consulting it first. This improves backward compatibility by
15235 better reflecting the way shell selection occurred in previous
15236 versions of Autoconf, and should help to avoid triggering latent
15237 problems in other packages, such as the one in Automake where zsh
15238 is not handled robustly:
15239 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
15240 Although it is not Autoconf's responsibility to work around
15241 problems in Automake, it nevertheless makes sense to avoid
15242 introducing unnecessary incompatibilites.
15244 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
15245 Gary V. Vaughan <gary@gnu.org>
15247 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
15248 how deeply nested we are when a suitable tool is found, set the
15249 ac_path_TOOL_found flag.
15250 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
15251 nested we are in this macro. Break out of all 3 nested loops if
15252 ac_path_TOOL_found is set.
15254 2004-04-21 Gary V. Vaughan <gary@gnu.org>
15256 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
15257 of the _AS_PATH_WALK loop too if GNU flavor is found.

15261 * doc/autoconf.texi (Limitations of Make): Update documentation
15262 for `$<'. New entry `Long lines', based on a report from Simon
15263 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
15264 paragraph about DJGPP, based on a mail from Richard Dawe.
15266 2004-04-20 Paul Eggert <eggert@twinsun.com>
15268 * tests/c.at (C keywords): Don't assume that GCC supports
15269 "restrict" and "inline", as sufficiently-old GCC versions do not
15270 (also, GCC configured to be in pedantic C89 mode does not).
15271 Problem reported by Sumit Pandya in:

15274 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
15275 consider -g to work if it generates warnings when plain compiles
15276 don't. Problem reported by Braden McDaniel in:
15277 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

15283 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
15284 linker output files before linking, to work around IRIX 6 linker bug.

15288 2004-04-20 Gary V. Vaughan <gary@gnu.org>
15290 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
15291 best tool so far counter rely on the tool path variable name to

15293 the length check on a previous tool.
15295 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
15296 match expression argument, as different greps have different
15297 regular expression flavours.

15310 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
15311 Types, Specific Compiler Characteristics, System Services,
15312 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
15313 etc. consistently instead of 'long', 'short', 'unsigned' etc.

15426 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
15427 (MAINTAINERCLEANFILES): Split into pieces,
15428 one per related section. Add $(srcdir)/wrapper.in.

15433 AC_SUBST provides no portable way to escape literal newlines.
15435 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
15436 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
15437 Darwin uses -lcrt2.o and there's little point to cataloging all
15438 the system variants. Partial fix reported by Andreas Waechter in:

15467 (AS_INIT): Output shell initialization there. Removed optional
15468 parameter. Expand _AS_SHELL_FN_SPY.

15516 the 2003-05-22 change, which removed the older years from the list.
15517 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

15525 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

15528 egrep and fgrep respectively if $GREP -E/-F don't work.
15529 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
15530 _AC_PROG_GREP, and AC_PROG_SED.
15531 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the

15561 2004-01-26 Paul Eggert <eggert@twinsun.com>
15563 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15564 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15565 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15566 not <inttypes.h>. Problem reported by Tim Mooney in
15567 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15568 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15571 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15572 otherwise "make check" fails because it forbids cmp (I guess
15573 because cmp treats files as binary on DOS-like systems).
15575 * tests/mktests.sh: Update copyright date to 2004, since some tests
15576 have changed in 2004.
15578 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15580 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15581 non-truncating sed or gsed program in PATH.
15582 * tests/acprograms.at: Add it.
15583 * doc/autoconf.texi (Particular Programs): Document it.
15586 2004-01-15 Paul Eggert <eggert@twinsun.com>
15588 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
15589 -std1 disables some useful extensions on Tru64. Problem reported
15590 by N. Lichtmaier in

15595 * doc/autoconf.texi (Programming in M4sh): Document that
15596 AS_MKDIR_P succeeds if the destination is a symbolic link
15597 to an existing directory.
15598 (Limitations of Usual Tools): Note that mkdir -p might not
15599 succeed on symlinks to directories.
15601 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15603 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

15617 2004-01-09 Paul Eggert <eggert@twinsun.com>
15619 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15620 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15621 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15622 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15623 AC_COMPILE_IFELSE, since we now assume our caller invokes
15624 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15625 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead

16116 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
16117 Reported by Ralf Corsepius.
16119 2003-09-26 Akim Demaille <akim@epita.fr>
16121 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
16123 Actually, use AU_ALIAS.
16126 2003-09-26 Paul Eggert <eggert@twinsun.com>
16128 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
16129 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
16130 Problem reported by Eric Sunshine in:

16135 The test suite are sometimes assigning timings incorrectly.
16136 Reported by Henk Krus.
16137 Diagnosed by Nicolas Joly.
16139 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
16141 Instead of making AT_help a sequence of assignments to grow
16142 $at_help_all, just make AT_help_all be the growing contents of
16143 $at_help_all, and make a single assignment in...
16145 (at_times_skip): Flip the meaning and rename as...
16146 (at_times_p): this.
16147 (AT_INIT): When summarizing the test that ran, remove
16148 $at_times_file after use, and check it is present before trying to

16155 * bin/Makefile.am (edit): Handle '@configure_input@'.
16156 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
16157 (ifnames): chmod -w.
16158 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
16159 executables, not bin/ executables! Otherwise all the magic needed
16160 to find non installed files is turned off. This caused a failure
16161 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
16162 as found in its environment (sent by tests/autoreconf): pointing
16163 to bin/autom4te that could not find its files.
16164 * tests/mktests.sh: Force the replacement of generated files, for
16165 the sake of "mv" program that are interactive when overwriting a
16167 * config/install-sh: Upgrade from CVS Automake.
16169 2003-09-23 Paul Eggert <eggert@twinsun.com>

16172 versus test -L issues.
16174 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
16175 Paul Eggert <eggert@twinsun.com>
16177 Trivial change to support GCC's configuration procedure.
16178 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

16215 2003-09-10 Akim Demaille <akim@epita.fr>
16217 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
16218 and AC_FC_FREEFORM.
16219 * tests/mktests.sh: Skip AC_FC_SRCEXT.
16220 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

16245 2003-09-04 Akim Demaille <akim@epita.fr>

16256 2003-09-04 Akim Demaille <akim@epita.fr>
16258 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
16260 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
16262 Add support for newer Fortran dialects. The F77 interface is
16263 unchanged, and continues to support Fortran 77. New FC macros
16264 correspond to all the old F77 macros, with output variables FC,
16265 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
16266 available dialect, but older dialects can be specified. There are
16267 new macros AC_FC_SRCEXT to set the source extension, and
16268 AC_FC_FREEFORM to accept free-form source files.
16270 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
16272 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

16306 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
16307 are defaulted by AT_CHECK anyway.
16308 Use AT_CHECK_AUTOM4TE.

16392 * lib/Autom4te/General.pm: Don't export error: you don't own it.
16394 2003-08-21 Akim Demaille <akim@epita.fr>
16396 First stab at preserving warnings between calls to autom4te,
16397 including when the cache is used.
16399 There are still several issues: (i) there are too many runs of m4
16400 (one for include, one for warnings, and some more), (ii) warnings
16401 spreading on several lines are not handled gracefully, (iii) the
16402 code meant to have the call stack display for errors does not work
16403 (its handling should move from m4 to autom4te).
16405 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
16407 (@preselect): Add m4_warn.
16408 ($exit_status): Remove, use $exit_code.
16409 ($help): Use Autom4te::ChannelDefs::usage.
16410 (&handle_m4): No longer define the m4_warnings.
16411 At each run, extract and report the warnings.
16412 Always cache the result, including if the exit status is on
16413 failure, since if nothing changes, we should result in the same
16414 failure, hence we can use the cache.
16415 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
16416 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
16418 (m4_warn): Redefine as a do-nothing: it is its invocation that
16419 matters, as warnings are now reported via traces.
16420 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
16421 the contents of m4_warn: make it _call_ m4_warn, so that tracing
16422 the latter reveals calls to the former.
16426 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

16448 (&catfile): Remove.
16449 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
16450 * bin/autoscan.in: Adjust.
16452 2003-08-20 Akim Demaille <akim@epita.fr>
16454 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
16455 Reported by Alexandre Duret-Lutz.
16457 2003-08-20 Akim Demaille <akim@epita.fr>
16459 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
16460 * bin/autom4te: Adjust.
16461 In particular, be Autoconf tools are really silent when properly
16462 working, bind the verbosity of the 'note' channel to $verbose.
16463 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
16464 (&xsystem, &contents): Remove, since they are exported by...
16465 * lib/Autom4te/FileUtils.pm: this.

16468 * lib/Autom4te/FileUtils.pm: here.

16526 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
16527 shorter column three. Add DESCRIPTION to log file content.
16529 2003-08-13 Derek Price <derek@ximbiot.com>

16585 2003-06-23 Akim Demaille <akim@epita.fr>
16587 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16588 not all of them. This fixes 1. the fact that when testing
16589 Autoconf there are many many config.log, 2. the incorrect use of
16590 top_srcdir to find config.log.
16591 Don't mix the detailed output of failed test with the summary of
16592 failures. Rather, append detailed log afterwards.

16599 2003-06-23 Akim Demaille <akim@epita.fr>
16601 * tests/torture.at (#define header templates): Don't use quotes in
16602 C++ comments as it puzzles Emacs' sh font-lock-mode.

16615 2003-06-21 Kevin Ryde <user42@zip.com.au>
16617 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
16618 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
16619 ensuring we add -std1 for full-ANSI.
16621 * doc/autoconf.texi (hdrindex): New macro.

16674 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.

16676 altered by WEXITSTATUS.
16677 (xqx, xsystem): Use handle_exec_errors.
16679 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
16681 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
16682 Do not call `_exit()', simply modify `$?'.

16684 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16685 63 for version mismatches.
16687 2003-05-23 Akim Demaille <akim@epita.fr>
16689 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16690 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16691 the middle of a line).
16692 * lib/m4sugar/m4sugar.m4: Likewise.
16693 Remove useless spaces in comments.
16695 2003-05-23 Akim Demaille <akim@epita.fr>
16697 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
16698 exit 63, so that we (or Automake's "missing") can tell the
16699 difference with a plain failure.
16700 * doc/autoconf.texi (Notices): Adjust.

16709 Paul Eggert <eggert@twinsun.com>
16711 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16712 Remove `#include <stdlib.h>' from the list; we should never
16713 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16714 resulting namespace pollution would cause other tests to fail.
16715 Configure scripts run with some older versions of g++ and HP's
16716 aCC would fail due to such an #include. Problems reported by
16717 Matthew Mueller in <http://bugs.debian.org/120704> and by
16719 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16720 In the test, use the test declaration before including <stdlib.h>,
16721 as that's closer to how it'll be used.
16723 2003-05-23 Akim Demaille <akim@epita.fr>
16725 * doc/autoconf.texi (Header Portability): ucred.h.
16728 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16730 Overhaul Autotest's logging: generate separate log files
16731 in testsuite.dir/NNN/testsuite.log, and append them to
16732 testsuite.log instead of re-running the test verbosely.
16734 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16735 file descriptor, write 0 to at_status_file instead of setting
16736 at_status=0, initialize some new variables (at_status_file,
16737 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16738 to rerun the tests, instead append the at_group_log to the
16739 at_suite_log when a test fails.
16740 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16741 with the AS_MESSAGE_LOG_FD redirected to stdout.
16742 (AT_CLEANUP): save the output status in $at_status_file
16743 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16744 its original place.
16745 (AT_CHECK): since tests are run with a redirected stdout,
16746 and used to be re-run in verbose mode, turn some $at_verbose
16747 into echo, and don't redirect the output of testing stdout
16750 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16751 the name of the debugging directory and information about
16754 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

16871 2003-05-06 Akim Demaille <akim@epita.fr>
16873 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16874 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16875 by aclocal.m4 is changed it might require the importing of another
16876 m4 extension file, i.e., aclocal must be run.
16878 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16879 (&parse_args): Use --force with aclocal if required and supported.

16889 open during the whole autom4te run.
16890 ($icache_file): New.

16893 2003-04-29 Derek Price <derek@ximbiot.com>
16895 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16896 seperator with m4_append_uniq(). It doesn't work.
16897 (AT_CLEANUP): Add `;' to end of at_help_all.
16898 (AT_INIT): Allow --keywords to be specified more than once. When
16899 grepping $at_help_all for keywords, use the field and keyword

16901 to support the new --keywords behavior.
16903 2003-04-27 Karl Berry <karl@freefriends.org>
16905 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16906 align better with others. I also made some of the individual
16907 entries on one line, for brevity and to make it easier for me to
16908 sort my dir-example file in the Texinfo distribution :).

16979 * tests/torture.at (Configuring subdirectories): Require aclocal
16980 1.4, otherwise the test fails, as it does support configure.ac.

17054 (Automake): Automake 1.5+ no longer requires special tools to be
17055 present on the developer's host.

17100 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
17101 format starting with "-".
17103 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
17105 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
17106 is not portable inside Makefile.
17108 2003-02-20 Akim Demaille <akim@epita.fr>
17110 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

17123 $ac_prefix_program.
17126 2002-12-23 Paul Eggert <eggert@twinsun.com>
17128 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
17129 innocuous variant befor including <limits.h> or <assert.h>. This
17130 works around a bug reported by Albert Chin: HP-UX 11i
17131 (and earlier versions) have a <limits.h> that declares
17132 gettimeofday and many other functions.
17134 2002-12-03 Paul Eggert <eggert@twinsun.com>
17138 * NEWS, configure.ac: Update version.
17140 * doc/fdl.texi: Upgrade to FDL version 1.2.
17142 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
17143 nontrivially in main's body, so that f's external declaration is
17144 not optimized away in AIX. This should fix the bug reported by
17146 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
17148 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
17149 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
17150 defined, to support freestanding compilers. This should fix the
17151 bug reported by Momchil Velkov in
17152 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
17154 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

17186 Update from masters.
17188 2002-11-14 Akim Demaille <akim@epita.fr>
17190 * Makefile.maint: Sync with Bison, i.e.:
17191 (po-check): Scan .l and .y files instead of the
17192 .c and the .h files that they generate. This fixes the bug
17193 reported by Tim Van Holder in:
17194 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
17195 Look for N_ as well as for _. Try to avoid matching #define for

17211 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
17212 than assigning in main, to avoid HP cc +O3 optimizing it away.

17216 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
17217 option. Process --recheck after parsing all options. Pass -q
17218 option to configure on --recheck.
17219 (AC_OUTPUT): Pass -q from configure to config.status.
17220 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from

17222 * doc/autoconf.texi (config.status Invocation): Document
17223 config.status -q option.
17225 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
17227 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
17228 Makefile.in if Makefile.am exists.
17229 (output): Strip `.am' from Makefiles. Don't
17230 output AC_CONFIG_FILES if no Makefiles were found.

17250 Reported by Ezra Peisach.
17252 2002-11-05 Akim Demaille <akim@epita.fr>
17254 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
17256 We _have_ to stop using the old compatibility scheme that tried to
17257 avoid useless backslashes because Libtool 1.4.3 contains a
17258 AC_DEFINE([error_t], [int],
17259 [Define to a type to use for \`error_t' if it is not
17260 otherwise available.])
17261 We _have_ to quote the single quote and backslashes with \. The
17262 old compatibility scheme saw that ` was backslashed, and therefore
17263 did not quote the single quote. Hence before this patch, Autoconf
17264 was not compatible with Libtool.
17266 2002-11-04 Paul Eggert <eggert@twinsun.com>
17268 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

17309 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
17310 Make variable, not a shell variable.
17311 Suggested by Bruno Haible.
17313 2002-10-31 Akim Demaille <akim@epita.fr>
17315 * bin/autom4te.in (load_configuration): Reject #args out of any

17342 * doc/autoconf.texi (Header Templates): Put also in words what the

17344 (Customizing autom4te): s/--cache=/--cache /.
17346 2002-10-29 Akim Demaille <akim@epita.fr>

17596 2002-10-22 Akim Demaille <akim@epita.fr>
17598 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
17599 are a few warnings.
17600 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
17601 Quote for Perl '' strings, not "".

17610 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

17615 `@', to tickle Perl's lists.
17616 Reported by Carlos Velasco.
17618 2002-10-18 Akim Demaille <akim@epita.fr>

17622 Thanks to Alexandre Duret-Lutz.

17651 2002-10-16 Akim Demaille <akim@epita.fr>
17653 Because of caching, some files that no longer exist and are no
17654 longer required can still cause errors.
17655 Reported by Alexandre Duret-Lutz.
17657 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
17658 to frozen files in @ARGV, as @ARGV must remain being a list of

17661 (&freeze): Use &error.
17662 (&up_to_date): If a file that was included according to the cache
17663 is no longer there, then the output is out dated.

17666 * tests/tools.at (autom4te cache): New.
17668 2002-10-16 Akim Demaille <akim@epita.fr>

17671 * bin/autoupdate.in (&parse_args): Kill old options.
17672 * bin/autoreconf.in (&parse_args): Remove dead options.
17674 (&autoreconf): Report the directories we enter *and leave*, so
17675 that error messages can be easily located, and use GNU Make
17676 format, so that Emacs' compile mode understands us.
17677 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
17678 if some file was changed instead of `print'.
17679 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

17713 file name to enable parallel executions.
17714 From Sam Varshavchik.
17716 2002-10-08 Akim Demaille <akim@epita.fr>
17718 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17719 aclocal invocation, as Gettext macros might not be visible to
17721 Instead of blindly running autopoint, scan configure.ac (not the
17722 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17723 Reported by Paul D. Smith.
17725 2002-10-08 Paul Eggert <eggert@twinsun.com>
17727 Work around problems found when POSIXLY_CORRECT=1 is set.
17728 None of this seems to have anything to do with POSIX, really,
17729 but it's how Perl getopt works.
17730 * bin/autom4te.in (parse_args): Configure GetOpt with
17732 * doc/autoconf.texi (Invoking autom4te):
17733 --warning -> --warnings.

17755 * tests/torture.at (Configuring subdirectories): Be robust to
17756 users who use config.site to require for a cache: in this case,
17757 the two last configure runs, using two different sets of
17758 arguments, trigger a legitimate error.
17760 2002-09-28 Akim Demaille <akim@epita.fr>

17795 tests/autom4te itself.

17797 (autoscan.list): New target --this file is no longer a source.

17822 * bin/autoscan.in (&init_tables): Adjust.
17824 2002-09-28 Akim Demaille <akim@epita.fr>
17826 From now on, autoscan files must always map a macro name to a

17829 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17831 * lib/autoscan/functions, lib/autoscan/headers: Make the macro

17922 Suggested by Guido Draheim.
17924 2002-09-13 Akim Demaille <akim@epita.fr>
17926 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17927 (chdir_init) might hang when stat'ing mounted directories.

17992 precious variables are.
17993 Suggested by Pontus Skoeld.

17997 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17998 (ifnames, autoscan, autom4te): Since we don't only depend on
17999 configure.ac variables (such as VERSION etc.), but also on prefix

18001 Reported by Alexandre Duret-Lutz.
18002 * doc/autoconf.texi (Installation Directory Variables): Adjust.
18004 2002-09-05 Kevin Ryde <user42@zip.com.au>

18054 * bin/autoupdate.in: Use error instead of die.
18056 2002-09-01 Paul Eggert <eggert@twinsun.com>
18058 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
18059 ordinary shell concatenation rather than echo+tr+sed command that
18060 runs afoul of a long-line-related sed bug in Solaris 8.
18062 * bin/autoheader.in (parse_args): --warning -> --warnings.
18064 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to

18071 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,

18074 * bin/autoconf.in, configure: Regenerate.
18076 * doc/autoconf.texi (Special Shell Variables): Mention
18077 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
18079 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
18080 MAILPATH and set PS1, PS2, PS4 to default values, to work
18081 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
18082 For LC_ALL etc, first try to set to "C" as POSIX requires and as
18083 the Autoconf documentation specifies; fall back to "unset" only if
18084 this fails. Use a shell for-loop for this rather than an m4 loop,
18085 to shorten the output script.
18087 2002-08-30 Paul Eggert <eggert@twinsun.com>
18089 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
18090 1003.1-2001's requirements for CDPATH. Give a simpler workaround
18091 for the CDPATH problem. Document PWD.
18092 (Limitations of Builtins): Document the problem that "cd $foo" and
18093 "ls $foo" may refer to different directories in shells conforming
18094 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
18095 example, since the old example is now out of date.
18097 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
18098 FOO" and "ls FOO" talk about different directories; this catches
18099 problems when POSIX 1003.1-2001 "cd" fails due to symlink
18102 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
18103 of rolling our own unset.
18104 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
18105 in practice we needn't worry about CDPATH if unset doesn't work.
18107 * Makefile.in, aclocal.m4, bin/Makefile.in,
18108 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
18109 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

18112 tests/Makefile.in: Regenerate with Automake 1.6.3.
18114 * config/config.guess, config/config.sub, config/mkinstalldirs:
18117 * configure: Regenerate with self.

18129 2002-08-29 Akim Demaille <akim@epita.fr>
18131 * lib/Autom4te/General.pm (&xqx): New.
18132 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
18133 hand, which is not portable.
18135 * bin/autom4te.in: Use them.
18136 Use &error instead of die.
18137 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
18140 2002-08-17 Paul Eggert <eggert@twinsun.com>
18142 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
18143 default list of compilers to try, since it was long ago superseded
18144 by the ksh fc builtin. Suggested by Steven G. Johnson.
18146 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
18148 * doc/autoconf.texi (Invoking autom4te): End the option table,
18149 fixing a bug introduced by the previous patch.
18150 (Limitations of Make): Add a 'target lookup' subentry in the
18151 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
18153 2002-07-29 Mark D. Roth <roth@feep.net>
18155 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
18156 options and use $AUTOM4TE_PATH.
18157 * doc/autoconf.texi: Remove documentation of autom4te
18158 --include-envvar and --site-macro-subdir options and document
18159 use of $AUTOM4TE_PATH.
18160 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
18161 arguments from each language section.
18163 2002-07-29 Paul Eggert <eggert@twinsun.com>
18165 * doc/install.texi: Include copyright symbol in copyright notice.
18167 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
18169 (AM_MAKEINFOFLAGS): New macro.
18170 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
18171 * Makefile.am (INSTALL): Use the new macros.
18172 Use -o rather than --output, since "missing" does not grok --output.
18174 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18176 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
18177 comments do not always work. Never trust the exit status of
18180 2002-07-24 Kevin Ryde <user42@zip.com.au>
18182 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
18183 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
18185 2002-07-23 Paul Eggert <eggert@twinsun.com>
18187 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
18188 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
18189 apparently treats PATH="nonexistent" as if it contained ".".
18190 Bug reported by Stefan `Sec' Zehl.

18316 2002-06-27 Paul Eggert <eggert@twinsun.com>
18318 * config/install-sh: Quote $src. Prefer || to test's -o option,
18319 as per "Limitations of Builtins".
18320 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
18321 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

18347 2002-06-11 Andreas Schwab <schwab@suse.de>
18349 * doc/autoconf.texi: Add more dir entries.
18351 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
18353 * bin/autom4te.in ($cache): Don't define using `$me', the name
18354 of the cache should not depend on the name under which autom4te

18448 2002-05-22 Paul Eggert <eggert@twinsun.com>
18450 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
18451 from the default list of compilers to try. Suggested by
18453 * NEWS: Document the above.
18454 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
18456 2002-05-17 Paul Eggert <eggert@twinsun.com>
18458 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
18459 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
18460 This improves on an earlier suggestion by H. Peter Anvin.
18462 2002-05-16 Paul Eggert <eggert@twinsun.com>
18464 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
18465 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
18466 Both macros now accept an optional source-dir arg.
18467 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
18469 * NEWS: Document this.
18470 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
18472 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
18473 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
18474 not for GNU extensions; this undoes part of the 2000-11-03 change,
18475 reverting to 2.13-compatible behavior.
18476 Add new optional argument DIR.
18477 (AC_FUNC_FNMATCH_GNU): New macro.
18479 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
18481 2002-05-08 Paul Eggert <eggert@twinsun.com>
18483 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18484 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18485 and it causes a 'test' syntax error if it fails.
18486 Bug reported by Stephen Gildea.
18488 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18489 If prototypes are supported, use them to check this at compile-time,
18490 instead of trying to check it at run-time. If we must do a run-time
18491 check, assume that setvbuf is standard when cross-compiling, as
18492 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18493 Bug reported by Paul D. Smith.
18495 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18496 argument specifying location of getloadavg.c. This removes a
18497 FIXME. This idea was taken from Jim Meyering's implementation in
18499 * doc/autoconf.texi (Particular Functions): Document this.
18500 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18501 that's what the code does; this fixes a bug reported by
18504 2002-05-03 Akim Demaille <akim@epita.fr>
18506 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18507 autopoint instead of gettextize.
18508 ($uses_alocal): Rename as...
18509 ($uses_aclocal): this.
18510 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18511 Suggested by Bruno Haible.
18513 2002-05-03 Akim Demaille <akim@epita.fr>
18515 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18517 2002-04-29 Paul Eggert <eggert@twinsun.com>
18519 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18520 files to be 1 second older; just set them to be the same time.
18521 Also, sleep 1 second after the first aclocal, to work around
18522 problems with sub-second time stamps on the input files.
18524 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18526 * doc/autoconf.texi: Mention "set -e -x" lossage
18527 under node "Limitations of Builtins".

18533 From Christian Cornelssen.
18535 2002-04-29 Akim Demaille <akim@epita.fr>
18537 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18538 of lack of $LINENO support, then the test will compare the $LINENO
18539 in testsuite vs. the lineno in the test file. This is wrong, of
18541 Be sure to protect it.
18542 Reported by Patrick Welche.
18544 2002-04-25 Akim Demaille <akim@epita.fr>
18546 * doc/autoconf.texi (Obsolete Macros): Typo.
18547 Reported by Vladimir Volovich.

18551 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18552 than some of the input files, hence, on the second run of aclocal,
18553 if some of its input are younger, make them older.
18554 Suggested by Paul Eggert.
18556 2002-04-25 Akim Demaille <akim@epita.fr>
18558 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

18564 and ac_subst_vars be sh variables containing the list of
18565 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
18567 (_AC_INIT_PREPARE): Use them to log them.
18568 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18569 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18570 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18571 _AC_SUBST_FILES and _AC_SUBST_VARS.
18572 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18574 2002-04-24 Akim Demaille <akim@epita.fr>
18576 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18577 autoheader, so that automake does not complain about a missing
18578 config.h.in that was to be created.
18580 2002-04-23 Akim Demaille <akim@epita.fr>
18582 * bin/autoheader.in (parse_args): --warning takes an argument.

18632 Minor spelling and grammar fixes.
18634 * doc/autoconf.texi: Follow the outline suggested in the GNU
18635 Sample Texts sections of the Texinfo 4.2 manual. Most
18636 importantly, this makes sure that the copyright notices appear in
18637 all output formats. You probably need Texinfo 4.2 to generate

18641 arguments in cases where this matters.

18664 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
18666 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
18667 from aclocal.m4 too.
18669 2002-04-12 Akim Demaille <akim@epita.fr>

18673 2002-04-10 Akim Demaille <akim@epita.fr>
18675 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
18676 workaround for ${1+"$@"}.
18677 * doc/autoconf.texi (Shell Substitutions): Explain it.
18678 From Oliver Kiddle and Peter Stephenson.
18680 Have M4sh perform minimal shell sanitizing.
18682 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18684 (_AS_PREPARE): this new macro.
18686 (AS_INIT): Invoke AS_SHELL_SANITIZE.
18687 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
18689 Adjust Autoconf and Autotest.
18691 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18692 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18693 * lib/autotest/general.m4 (AT_INIT): Likewise.
18694 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
18695 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
18698 Use this M4sh to generate Autoconf's shell scripts.
18700 * tests/wrapsh.as: New, precursor of wrapsh.in.
18701 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18702 on Autotest and M4sh.
18703 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18704 (wrapsh.in): New target.
18705 * bin/autoconf.as: New, precursor of autoconf.in.
18706 (autoconf.in): New target.
18708 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

18711 with indented comments in rules.
18713 2002-04-09 Andreas Schwab <schwab@suse.de>
18715 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
18716 ac_top_builddir when setting ac_abs_top_builddir.

18720 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
18721 (Portable Shell): Cross reference to Systemology.
18723 2002-04-05 Akim Demaille <akim@epita.fr>
18725 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
18726 directories when descending in a SUBDIRS.
18727 Reported by Ezra Peisach.
18729 2002-04-04 Andreas Schwab <schwab@suse.de>
18731 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18732 contains no literal separators.
18734 2002-04-03 Akim Demaille <akim@epita.fr>
18736 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18737 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18738 Use dnl, not the KILL diversion.
18740 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18741 (AC_CONFIG_LINKS): here.
18743 Don't use the KILL diversion, as it kills spurious output, which
18744 results in failures being hidden.
18745 Use m4_defn where appropriate.
18746 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18747 after the second argument.
18749 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18750 syntax, as it is provided by M4sugar.

18753 2002-04-03 Andreas Schwab <schwab@suse.de>

18756 expanded if $# <= 2.

18772 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
18774 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
18775 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18776 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

18778 (AC_C_CONST): Same.
18779 (AC_C_INLINE): Same.

18788 _AS_MKDIR_P_PREPARE.
18790 2002-03-28 Kevin Ryde <user42@zip.com.au>
18792 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18793 to avoid versions of HP C which don't allow that.
18795 2002-03-27 Paul Eggert <eggert@twinsun.com>
18797 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
18798 (AS_SHELL_SANITIZE): Invoke it.
18799 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

18809 2002-03-25 Paul Eggert <eggert@twinsun.com>
18811 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18812 as POSIX requires, as it doesn't work with Zsh.
18813 * doc/autoconf.texi (Assignments): Document the problem.
18815 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18817 * doc/autoconf.texi (Limitations of Make): Mention more issue
18818 about VPATH, overriding of macros in sub-makes, and handling of
18821 2002-03-21 Paul Eggert <eggert@twinsun.com>
18823 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18824 problem with here-document buffer boundaries.
18826 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18827 when reinvoking the shell, to work around problems with installers
18828 who put strange things like "cd" commands in their environments.
18830 2002-03-19 Akim Demaille <akim@epita.fr>

18848 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

18852 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18853 (Limitations of Usual Tools): Add mkdir section.
18855 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18856 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18857 back on AS_DIRNAME to compute prefixes otherwise; this is
18858 roughly what mkinstalldirs does. That way, we need not have
18859 our own filename disassembler. The old disassembler did not
18860 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18862 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18863 Create at_test_all by a series of assignments,
18864 not by a single assignment of a long string. The latter causes ksh
18865 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18866 presumably because of a buffer overrun.
18868 2002-03-14 Paul Eggert <eggert@twinsun.com>
18870 * lib/autotest/general.m4 (at_times_skip):
18871 Renamed from at_times. Now a boolean.
18872 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18873 says 'times: not found'.
18875 2002-03-14 Akim Demaille <akim@epita.fr>
18877 * bin/autoreconf.in (&study_gettextize): New.
18878 (&autoreconf): Handle newest gettextize.

18888 * doc/autoconf.texi (Header Portability): New.
18889 Add information about stdint.h and inttypes.h from Paul Eggert.
18891 2002-03-13 Akim Demaille <akim@epita.fr>

18902 2002-03-11 Andreas Schwab <schwab@suse.de>
18904 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
18905 does not do it if --with-lispdir is given.

18911 2002-03-08 Akim Demaille <akim@epita.fr>

18914 subdirectory should exist.
18916 2002-03-08 Akim Demaille <akim@epita.fr>
18918 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18920 2002-03-08 Akim Demaille <akim@epita.fr>
18922 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18923 aliases the actual variables, and modifications of the former
18926 2002-03-08 Akim Demaille <akim@epita.fr>
18928 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18929 because of C-c: have m4 output in tmp files, then mv them.
18931 2002-03-08 Akim Demaille <akim@epita.fr>

18950 2002-03-04 Akim Demaille <akim@epita.fr>
18952 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18953 * lib/autoconf/general.m4 (AC_INIT): More informative error
18954 message for LIBOBJ.
18956 2002-03-04 Akim Demaille <akim@epita.fr>

18961 2002-03-04 Akim Demaille <akim@epita.fr>
18963 * doc/autoconf.texi (Transforming Names): Equality between target
18964 and host is irrelevant.
18965 (Specifying Names, Canonicalizing): Remove all references to the
18966 backward compatibility hooks. Rather, collect them all into...
18967 (Hosts and Cross-Compilation): this new section.
18968 * doc/install.texi (System Type): Ditto.
18969 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18970 that `--host' implies cross-compilation.
18972 2002-03-04 Akim Demaille <akim@epita.fr>
18974 * doc/autoconf.texi (Evaluation Macros): New.
18975 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18977 (_m4_foreach): Define the variant with immediate evaluation so
18978 that it contains exactly the items, not an expression which
18979 evaluation is the current item.
18980 (m4_re_string, m4_re_word): Don't over quote them.
18982 2002-03-04 Akim Demaille <akim@epita.fr>
18984 Instead of having stacking `shift's evaluated at the end, let
18985 `foreach' loops immediately evaluate them.
18987 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18988 $*. This is the n-th time I change my mind, but hopefully this is
18991 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18993 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18994 it was only a hack for m4_text_wrap.
18995 (m4_car2): Remove, replaced by...
18997 (_m4_foreach): Adjust.
18998 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18999 m4_bpatsubst for clarification.

19065 case/esac, some shells don't support it.
19066 Reported by Zack Weinberg.

19069 2002-02-06 Akim Demaille <akim@epita.fr>
19071 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
19072 sure not to introduce newlines in at_groups.
19073 * lib/autotest/Makefile.am (autotest.m4f): Typo.
19075 2002-02-06 Akim Demaille <akim@epita.fr>
19077 * tests/torture.at (Configuring subdirectories): Skip if aclocal
19080 2002-02-05 Paul Eggert <eggert@twinsun.com>
19082 * doc/autoconf.texi (Specific Compiler Characteristics):
19083 Describe HP-UX cc bug workaround more accurately.
19084 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
19086 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
19087 cross-compilers, too. This undoes some of the most recent change
19090 2002-02-05 Akim Demaille <akim@epita.fr>
19092 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
19093 to make sure they are up to date when `check' is run.
19095 2002-02-05 Akim Demaille <akim@epita.fr>
19097 * doc/autoconf.texi (Making testsuite Scripts): Document
19100 2002-02-05 Akim Demaille <akim@epita.fr>
19102 * lib/freeze.mk: New.
19104 2002-02-05 Akim Demaille <akim@epita.fr>
19106 Implement `autom4te --freeze'.
19108 * bin/autom4te.in (&freeze): New.
19109 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
19110 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
19112 2002-02-05 Akim Demaille <akim@epita.fr>
19114 * bin/autom4te.in (&parse_args): Implement `frozen files are
19115 optional are the sum of the previous files on the command line'.
19116 Also, pass `--reload-state=' on them, so...
19117 (handle_m4): don't.
19118 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
19119 (M4sh): Rely on M4sugar.
19120 (Autotest, M4sh, M4sugar): Use frozen files.
19122 2002-01-31 Akim Demaille <akim@epita.fr>
19124 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
19125 * doc/autoconf.texi (Initializing configure): Adjust.
19127 2002-01-30 Akim Demaille <akim@epita.fr>
19129 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
19130 alphanumeric to `-' instead of `_'.
19132 2002-01-30 Akim Demaille <akim@epita.fr>
19134 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
19135 for plain code, the other for cross-compilation code. The latter
19136 is now run with GCC only.

19144 change AC_INIT default values.
19146 2002-01-29 Akim Demaille <akim@epita.fr>
19148 * tests/torture.at (Configuring subdirectories): Use configure.in,
19149 so that aclocal 1.4 works.
19150 Reported by Alexandre Duret-Lutz and Larry Schmitt.
19152 2002-01-28 Akim Demaille <akim@epita.fr>
19154 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
19157 2002-01-28 Akim Demaille <akim@epita.fr>
19159 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
19160 AUTOTEST_PATH *after* it was set.
19161 Don't put `.' in the PATH: the user should be precise and `./' if
19162 needed. In addition, given that the test suite does some `cd', if
19163 `.' is in the path, the `tested programs' sections will report
19164 programs found in the test suite's directory, while during the
19165 tests (performed in their own directory), these programs are no
19166 longer visible. In other words, the results is confusing and
19168 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

19181 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
19182 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
19183 Bourne. Use /bin/sh.
19184 From Andreas Buening.
19186 2002-01-24 Akim Demaille <akim@epita.fr>
19188 * config/config.guess, config/config.sub, config/texinfo.tex:

19212 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
19213 message on invalid options.
19214 * bin/autom4te.in (parse_args): Don't use
19215 Autoconf::General::getopt with non valid options.
19217 2002-01-17 Jim Meyering <meyering@lucent.com>
19219 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
19220 $ac_cv_exeext so we don't use an old, invalid, cached value.
19222 2002-01-11 Akim Demaille <akim@epita.fr>

19234 package.m4, since is really depends upon configure.ac, not
19236 * doc/autoconf.texi (testsuite Scripts): Adjust.
19237 * tests/Makefile.am (package.m4): New.
19238 EXTRA_DIST it since its a source.
19240 2002-01-06 Akim Demaille <akim@epita.fr>
19242 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
19243 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
19244 and PACKAGE_BUGREPORT from here...
19245 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
19247 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
19248 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
19249 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
19250 * tests/tools.at (autoheader): Adjust.
19251 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
19253 2002-01-06 Akim Demaille <akim@epita.fr>

19270 * doc/autoconf.texi (New Macros): Tweak wording.
19272 2001-12-14 Akim Demaille <akim@epita.fr>
19274 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
19275 trailing files, don't apply `-rf' to files which might not be
19276 created by configure (core, core.*, and *.core), but just `rm -f'.
19277 Suggested by Jonathan Kamens.
19279 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
19281 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
19283 2001-12-14 Akim Demaille <akim@epita.fr>
19285 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
19287 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
19289 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
19290 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
19291 abs_srcdir, top_srcpath to abs_top_srcdir.
19292 (_AC_OUTPUT_FILES): Adjust.
19293 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
19294 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,

19303 2001-12-12 Kevin Ryde <user42@zip.com.au>
19305 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
19306 forbidden file descriptors table.
19308 2001-11-26 Akim Demaille <akim@epita.fr>
19310 * bin/autoscan.in (%c_keywords): Build it at top level.
19311 Map to 1 in order to simplify its uses.
19313 2001-11-26 Akim Demaille <akim@epita.fr>
19315 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
19316 Remove $filepath, useless.
19317 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
19318 variables, they are really part of the tokens.
19319 Split the input line on spaces and then look for tokens.
19320 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
19321 because of `lex$U.$(OBJEXT)'.
19322 (&scan_files): Use "@list" instead of join.
19323 * doc/Makefile.am (CLEANFILES): Add *.fns.
19325 2001-11-26 Akim Demaille <akim@epita.fr>

19328 Remove, replaced by...
19329 * tests/wrappl.in: Be common for all the Perl executables.
19330 In particular autoscan and autoheader want -I.
19331 * configure.ac: Adjust.
19332 * lib/autoscan/headers: errno.h is portable.
19334 2001-11-26 Akim Demaille <akim@epita.fr>
19336 * bin/autoscan.in (used): New.
19339 2001-11-26 Akim Demaille <akim@epita.fr>
19341 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
19343 (&scan_sh_file): Remove a duplicate pattern.
19344 (&check_configure_ac): Use long options.
19345 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

19350 Before, having a line containing the opening of a multi line
19351 comment made the whole line be ignored.
19353 2001-11-26 Akim Demaille <akim@epita.fr>
19355 * doc/autoconf.texi (Using an Autotest Test Suite): New.

19361 Test groups are now run two directories deeper.
19363 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
19364 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
19366 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
19367 top_srcdir, builddir and top_builddir.
19368 Use `at_*dir' relatively to the directory containing the
19369 suite, use `*dir' when relatively to the current group dir.
19371 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
19373 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
19374 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
19375 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
19378 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
19380 * doc/autoconf.texi (Using System Type): Add an example of `case
19381 $host' usage so people quit using `case $target' everywhere.
19383 2001-11-22 Akim Demaille <akim@epita.fr>
19385 * doc/autoconf.texi (Installation Directory Variables): Englishoes
19386 spotted by Jim Meyering.
19388 2001-11-16 Paul Eggert <eggert@twinsun.com>
19390 This patch implements a `long double' suggestion by Oliver Kiddle.
19392 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
19393 static, to catch errors if the value isn't known at compile-time
19394 and the compiler supports dynamic arrays. Change its name from
19395 `_array_' to `test_array' to avoid potential name clashes.
19396 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
19397 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
19398 better than double. Catch a bug in GCC 2.95.2 x86.
19399 * doc/autoconf.texi (C Compiler): Document the above.
19402 2001-11-13 Akim Demaille <akim@epita.fr>
19404 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
19406 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
19408 2001-11-13 Akim Demaille <akim@epita.fr>
19410 * lib/autotest/general.m4 (AT_INIT): After having run the test
19411 group, go back to the initial directory, not to at_suite_dir.
19413 2001-11-13 Akim Demaille <akim@epita.fr>
19415 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
19416 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
19417 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
19419 (AT_CHECK_CONFIGURE): Use absolute paths.
19420 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
19421 The problem is still the old one: there is no means in M4 (that I
19422 know about) to create a defining macro, because there is no means
19423 to create `$1' etc., therefore, the defining macro ``swallows''
19424 all the arguments meant to the defined macro.
19426 2001-11-13 Akim Demaille <akim@epita.fr>
19428 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
19429 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
19431 * tests/aclocal.m4: Remove, as it is no longer used.
19433 2001-11-13 Akim Demaille <akim@epita.fr>
19435 * lib/autotest/general.m4: Change `tests?' into `groups?' in
19436 variable names when referring to a single test group, or to
19437 `suite' when referring to the whole test suite.
19438 `at_last_test' is removed: m4 compute at_format itself.
19439 (at_stdout, at_stder1, at_stderr): New variables.
19440 (AT_CHECK): Use them.
19442 2001-11-13 Akim Demaille <akim@epita.fr>
19444 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
19446 Create `testsuite.dir/003/run' instead of `testsuite.003'.
19447 Do it as soon as a test fails, don't wait till the end of the test
19449 Don't remove $as_me.[0-9]*, since these files no longer exist.
19451 2001-11-13 Akim Demaille <akim@epita.fr>
19453 * tests/tools.at: Use absolute paths, since we are no longer run
19456 2001-11-13 Akim Demaille <akim@epita.fr>
19458 Now that tests are running in their own private dir, there is no
19459 need to list the files to remove at the end of tests groups.
19461 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
19462 (AT_data_files, at_data_files): Remove.
19463 (AT_CLEANUP, AT_DATA): Simplify.
19465 Remove the group dir if !debug && !failed.
19466 * tests/atspecific.m4: Adjust.
19468 2001-11-13 Akim Demaille <akim@epita.fr>
19470 Start a new layout for Autotest: `testsuite' creates
19471 `testsuite.dir' in which the at-check-line etc. files are to be
19472 found, and `testsuite.dir/003' where the test group 3 is run.
19474 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
19475 at_check_line_file, at_format, at_test_normalized, at_group_dir
19477 Create the directories.
19478 Use absolute paths for at- files.
19479 (AT_CHECK): Adjust.
19481 2001-11-11 Michael Matz <matz@kde.org>
19483 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
19485 (m4_car): Properly quote arguments.
19487 2001-11-13 Akim Demaille <akim@epita.fr>
19489 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
19490 with stricter rules on LIBOBJS.
19492 2001-11-12 Paul Eggert <eggert@twinsun.com>
19494 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
19495 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
19498 2001-11-12 Akim Demaille <akim@epita.fr>
19500 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
19502 2001-11-12 Akim Demaille <akim@epita.fr>
19504 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
19505 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
19506 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
19507 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
19508 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
19509 specify to what the macro should be defined (typically to 1).
19511 2001-11-12 Akim Demaille <akim@epita.fr>
19513 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
19516 2001-11-12 Akim Demaille <akim@epita.fr>
19518 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19519 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19520 definition used by Automake where LEX is +/- "${missing} lex" and
19521 `missing' itself contains variables.
19523 2001-11-12 Akim Demaille <akim@epita.fr>
19525 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19526 Now that M4sh pushes BODY, the comments were output at the end of
19529 2001-11-08 Akim Demaille <akim@epita.fr>
19531 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19532 that we can trace macros from aclocal.m4.
19533 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19534 obsoleted, and redirect to the former anyway.
19535 Reported by Ralf Corsepius.
19537 2001-11-08 Akim Demaille <akim@epita.fr>
19539 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
19540 processed only if present.
19541 * tests/torture.at (Configuring subdirectories): Use autoreconf
19542 instead of successive calls to autoconf.
19543 Add a nonexistent subdirectory to exercise the patch above.
19544 Reported by Ralf Corsepius.
19546 2001-11-08 Kevin Ryde <user42@zip.com.au>

19613 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19614 passed on command line, defaulting to ./configure.ac if present.
19615 (&maybe_autoreconf, File::Find): Remove, unused.

19639 2001-11-01 Paul Eggert <eggert@twinsun.com>
19641 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19642 be invoked before _AS_LINENO_PREPARE.
19643 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19644 than character ranges.
19646 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19647 invoking AS_BASENAME. Set the locale variables to 'C' if
19648 possible, as POSIX requires this to get the traditional
19650 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19652 2001-10-31 Paul Eggert <eggert@twinsun.com>
19654 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19655 with {}, as that triggers a bug in Bash 2.05.
19657 (_AS_LINENO_PREPARE): Use Sed rather than
19658 Awk. Fix the sed prepass to work even if there are multiple
19659 instances of $LINENO on the same line. Do not substitute for
19660 other variables like $LINENOT. Do not check file dates; such a
19661 check is unreliable on sufficiently fast machines, and removing
19662 the check makes the code simpler and more reliable. Check for
19663 output and chmod failures.
19665 * doc/autoconf.texi (Special Shell Variables): Document
19668 2001-10-31 Akim Demaille <akim@epita.fr>

19675 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
19676 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
19677 provided, while it is optional.
19678 * configure.ac: Adjust.
19680 2001-10-26 Paul Eggert <eggert@twinsun.com>
19682 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19683 lib/Autom4te/Struct.pm:
19684 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19687 * doc/autoconf.texi (Special Shell Variables): Document some
19688 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19690 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19691 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19692 eval $LINENO is not portable in practice.
19694 2001-10-24 Akim Demaille <akim@epita.fr>
19696 * lib/Autom4te/General.pm (backname): New.
19698 2001-10-24 Akim Demaille <akim@epita.fr>

19708 2001-10-22 Paul Eggert <eggert@twinsun.com>
19710 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19711 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19712 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19713 POSIX decided to standardize on the int flavor of strerror_r.
19714 Always do char* test, as there's no reason not to.
19715 Assign to a char* var, to catch strerror_r that returns int*.
19717 * doc/autoconf.texi (Particular Functions):
19718 Document the above changes. Also, document the fact that
19719 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19721 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19723 2001-10-20 Akim Demaille <akim@epita.fr>

19734 (&autoreconf): Display the full path of the configure.ac we are
19736 Trace it only once.
19737 Be sure to honor --force with gettextize.
19738 Always run aclocal.
19739 * doc/autoconf.texi: Adjust.
19741 2001-10-20 Akim Demaille <akim@epita.fr>
19743 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19745 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19746 `intl' is already present, as it refuses unless --force.
19747 (&parse_args): Use -I, --include instead of the old Autoconf
19749 ($localdir, $autoconf_dir): Remove.
19751 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19753 2001-10-19 Jens Petersen <petersen@redhat.com>
19755 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

19774 configure.ac being studied.
19776 2001-10-18 Paul Eggert <eggert@twinsun.com>
19778 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19779 long, to work around a bug in the HP C compiler version HP92453-01
19782 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19783 (AS_BASENAME_EXPR): New macro.
19784 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19785 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19786 and fall back on 'sed' only if the other two fail. This makes
19787 AS_BASENAME act more like AS_DIRNAME.
19788 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19789 contains white space.
19790 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19791 Use AS_DIRNAME, since I think it's now DOS-friendly.

19844 bother with $force since...
19845 * lib/Autom4te/General.pm: does.
19847 2001-10-08 Akim Demaille <akim@epita.fr>
19849 * bin/autoreconf.in: Rewrite in Perl.
19850 * configure.ac: Adjust.

19933 shell does not support LINENO, and if CONFIG_SHELL is unset or
19934 empty, and if we can find a shell that does support LINENO,
19935 then set CONFIG_SHELL to that shell and then re-execute
19936 ourselves with CONFIG_SHELL.
19938 2001-10-05 Paul Eggert <eggert@twinsun.com>
19940 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
19941 doesn't exist. Remove *.tmp, as a .tmp file is created during the

20011 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
20012 Don't use nested parenthesization. This patch was originally
20013 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
20014 but somehow it didn't get incorporated then.
20015 * doc/autoconf.texi (Limitations of Usual Tools):

20018 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
20019 Report an error if the size cannot be determined even though
20021 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
20022 Check for `expr' arithmetic overflow, and for compilation failure,

20256 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
20257 Do not pass a first argument with leading '-'
20258 to expr, by parenthesizing initial integers that might be negative.
20260 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP

20264 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
20265 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check

20284 Add test for AS_BASENAME.

20286 added test. It now correctly handles /1/2/3/, returning '3' not ''.
20287 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
20288 * tests/base.at: Fixed the expected responses. The old ones were
20290 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
20291 the documentation claims it should (and how it behaved in 2.13).
20293 2001-09-18 Akim Demaille <akim@epita.fr>
20295 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

20306 the only optional argument is the name of the test suite.
20307 Expect `package.m4' to define the package signature.

20332 fprintf "%d" only after ensuring the argument is of type 'int'.
20333 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
20335 2001-09-17 Paul Eggert <eggert@twinsun.com>
20337 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
20338 or CFLAGS=-O5. In that case, the linker has a relaxed view of
20339 fatal errors, and AC_CHECK_LIB causes it to include libraries even
20340 when they don't exist.
20342 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
20343 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
20346 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
20347 version with the version used by fileutils 4.1, except use

20498 to avoid GCC warnings.
20501 2001-09-05 Akim Demaille <akim@epita.fr>
20503 * bin/autom4te.in: --language is -l, not -s.
20505 2001-09-05 Akim Demaille <akim@epita.fr>
20507 Be ready to handle filenames as stupid as `dnl.at', for if even
20508 the maintainer is dumb enough to do that...
20510 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
20511 excellence in M4 quotation: consider `__file__' is active.
20513 And BTW, when invoking m4, pass the --include in the right order:
20516 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

20539 2001-09-05 Akim Demaille <akim@epita.fr>
20541 CVS GNU M4 doesn't like `undefine(undefined)'.
20543 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
20544 New, extracted from main.
20545 Use IO::File wherever possible.
20546 (input.m4): Be constant, use -I instead of hard coding $tmp.
20547 Therefore be a quoted heredoc.
20548 Don't invoke `_au_disable', since ac was not loaded, but just

20574 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
20576 2001-08-31 Akim Demaille <akim@epita.fr>
20578 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
20579 (testsuite Scripts): There is no such thing as `atconfig.in'.
20580 And actually one diagram is missing: test suite runtime.
20582 2001-08-31 Akim Demaille <akim@epita.fr>
20584 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
20587 2001-08-31 Akim Demaille <akim@epita.fr>
20589 * bin/autoupdate.in (@include): `installcheck' revealed the path
20590 to m4sugar was lacking!
20592 2001-08-31 Akim Demaille <akim@epita.fr>
20594 * man/Makefile.am (.x.1): We really have to pass
20595 autom4te_perllibdir.

20605 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
20606 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
20607 Use directly autom4te, not autoconf.

20633 (autoheader): Pass --force since the test suite goes too fast for
20635 Adjust to the new autoheader messages.

20650 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
20651 `autoheader: `config.hin' is created'.
20652 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
20654 2001-08-31 Akim Demaille <akim@epita.fr>

20662 Map --localdir, --autoconf-dir onto it.
20663 Forward autom4te's options instead of interpreting them.

20665 There is no such envvar since the inception of autom4te.cfg.
20666 * bin/autom4te.in (&parse_args): Uniquify `@include'.
20667 * bin/autoupdate.in: Adjust, and perform more control.

20669 * tests/autoconf: Dittowise.
20671 2001-08-31 Akim Demaille <akim@epita.fr>

20687 * lib/Autom4te/General.pm (&find_peer): Remove.
20688 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
20689 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
20690 * man/Makefile.am: Let help2man rely on PATH instead of trying to
20691 find the executables for it.
20692 * tests/Makefile.am: Major cleanup. Too lazy to document...
20693 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20695 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20696 indeed related to running the test suite, while passing
20697 --autoconf-dir and others is related to running non installed
20698 Autoconf executables. So don't do that, leave it to...
20699 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
20700 * tests/autoscan: New.
20701 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20718 Suggested by Paul Eggert.
20720 2001-08-29 Akim Demaille <akim@epita.fr>
20722 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
20723 download in a tmp dir.
20725 2001-08-29 Akim Demaille <akim@epita.fr>
20727 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

20747 foo=`(command) 2>/dev/null`

20751 (AT-devnull): this.

20898 the name of the directory they're in, instead of the filename,

20987 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
20988 * NEWS, README, README-alpha, TODO, tests/README: This package is
20989 `Autoconf', not `autoconf' (the executable).
20991 2001-08-20 Akim Demaille <akim@epita.fr>
20993 Info readers seem to need `Index' in the index node title :(
20995 * doc/autoconf.texi: Reverse the 2001-08-15 change which

21040 2001-08-20 Akim Demaille <akim@epita.fr>
21042 Huh!?!?! There are still some user EOF tags used, which prevents

21045 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
21046 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

21109 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

21127 * doc/autoconf.texi: Work around Texinfo buglets.
21128 (Transformation Rules): One example is enough, users are expected
21129 to have their brains on. And BTW, use DESTDIR.
21130 (dvar): New macro. Use it.
21132 2001-08-17 Akim Demaille <akim@epita.fr>
21134 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

21187 autom4te.cache (it's a directory, not a file.
21188 * Makefile.am: Ditto (but maintainer-clean-local).
21190 2001-08-15 Akim Demaille <akim@epita.fr>
21192 * bin/autom4te.in (@m4_warning): New.
21193 (&handle_m4): Use it.
21194 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
21195 warnings are issued at each run.
21196 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
21197 is in the src tree.
21199 2001-08-15 Akim Demaille <akim@epita.fr>
21201 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
21202 don't waste time running `autoupdate --version' works.
21203 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
21205 2001-08-13 Akim Demaille <akim@epita.fr>

21264 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
21266 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
21267 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
21268 * doc/autoconf.texi (C Compiler Characteristics): Update
21269 documentation for AC_C_BIGENDIAN.
21271 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

21274 magic values from an object file when cross-compiling.
21275 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
21277 2001-08-10 Akim Demaille <akim@epita.fr>
21279 * bin/autom4te.in (&handle_output): Don't use `grep' with side
21281 Suggested by Russ Allbery.
21283 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
21285 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
21286 current $prefix to the sub-configures.
21288 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
21290 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
21291 extension (needed on BeOS). Reported by Guido van Rossum.
21293 2001-08-09 Akim Demaille <akim@epita.fr>
21295 * bin/autom4te.in ($icache): Load it only if older than autom4te.
21297 2001-08-07 Akim Demaille <akim@epita.fr>
21299 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
21301 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
21302 No need to remove the files before and after the each test, before
21303 each test and at the end of the suite is enough.
21304 Display only the children `times', not the shell's.
21305 If the test failed or was skipped, at-times is not available.
21307 2001-08-07 Akim Demaille <akim@epita.fr>
21309 Always produce testsuite.log, including when there are no
21310 failures. This helps getting information on skipped tests, and
21311 duration of the tests. Err, implement the latter btw.
21313 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
21314 Dump information on the first run of each test.
21315 (AT_CLEANUP): Create `at-times' containing the duration of the
21318 2001-08-07 Akim Demaille <akim@epita.fr>
21320 The use of `dumpstat' revealed that `len' was used although it
21321 should not. m4_text_wrap was using it, but in the Autoconf world
21322 where it is legal. Hence (i) test M4sh in its own world, not
21323 Autoconf's, and (ii), ahem, fix the bug :)
21325 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
21326 does not like `' instead of [].
21327 (AT_INIT): Forbid `^_?AT_'.
21328 And don't output such tokens.
21329 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
21330 `script.as', and `autom4te.cache'.
21331 Remove `empty' and `macro' which are no longer used.
21332 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
21333 * tests/m4sugar.at: Use it.
21334 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
21336 2001-08-07 Akim Demaille <akim@epita.fr>
21338 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
21340 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
21342 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
21344 2001-08-04 Akim Demaille <akim@epita.fr>
21346 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
21347 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
21349 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
21350 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
21351 (AC_F77_MAIN): Likewise.
21353 2001-08-04 Akim Demaille <akim@epita.fr>
21355 Don't rely on M4sugar outputting the patterns in files, since we
21356 might process the output _without_ running m4, hence without these
21359 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
21360 * bin/autom4te.in (@Request::includes): Remove, unused.
21361 (@Request::source): Rename as...
21362 (@Request::input): this.
21363 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
21364 (&handle_output): Fetch the patterns from the traces.
21365 `$forbidden' and `$allowed' are constant: use m//o.
21366 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
21367 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
21369 2001-08-04 Akim Demaille <akim@epita.fr>
21371 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
21372 autoconf', i.e., in addition to caching traces, cache the output.
21374 * bin/autom4te.in (Request::cache): Rename as...
21375 (Request::id): this.
21376 ($cache, $icache, $tcache, $ocache): New.
21377 (&handle_m4): Save M4 output in the cache instead of $tmp.
21378 (&handle_output): Adjust.
21379 (&up_to_date_p): Check that the output cache is up to date too.
21380 (top level): Run `&handle_m4' iff force or the cache is invalid.
21381 Run `&handle_output' if the output cache is more recent.
21383 2001-08-04 Akim Demaille <akim@epita.fr>
21385 * bin/autom4te.in ($force): New.
21386 (&parse_args, &print_usage): -f, --force is a new option.
21387 (&handle_output): CPP directives might have spaces after `#'.
21388 (&parse_args): The first file only can be frozen.
21390 2001-08-04 Akim Demaille <akim@epita.fr>
21392 Don't let autom4te compute the `include' traces several times:
21393 first check that the trace cache file is up to date, and then
21394 compare its timestamp with that of the output.
21396 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
21397 the preamble. Don't require 5.005 as Autom4te::General does it,
21398 and better yet (use `use', not `require'!).
21399 * lib/Autom4te/Struct.pm: Rename the last occurrences of
21400 Class::Struct as Autom4te::Struct.
21401 * lib/Autom4te/General.pm (File::stat): Use it.
21402 (&mtime): New, export it.
21403 * bin/autom4te.in: Use it.
21404 Declare `$req' is invalid if it is outdated.
21405 Don't declare it valid before saving it if something went wrong.
21407 2001-08-04 Akim Demaille <akim@epita.fr>
21409 Autom4te shall not encode Autoconf data, and preselecting traces
21410 must be proposed to the users.
