3 Minor testsuite improvements.
4 * lib/autotest/general.m4 (AT_INIT) <PREPARE_TESTS>: Use fewer
5 forks when sanitizing PATH. Always output machine information,
6 not just when atconfig was located.
8 Add 'testsuite -C dir'.
9 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
11 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
13 <DEFAULTS>: Delay computation of variables based on $at_dir...
14 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
15 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
16 <PARSE_ARGS>: Parse new option.
17 <HELP_TUNING>: Document it.
18 * tests/autotest.at (Choosing where testsuite is run): New test
20 (Keywords and ranges): Add test for missing -k argument.
21 * NEWS: Document this.
22 * doc/autoconf.texi (testsuite Invocation): Likewise.
24 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
26 * build-aux/config.guess, build-aux/config.sub,
27 build-aux/texinfo.tex: Sync from gnulib.
28 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
31 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
33 * doc/autoconf.texi (Particular Programs): Do not mention the
34 Autoconf version in which the AC_PROG_INSTALL change was done.
35 Suggested by Paul Eggert.
37 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
39 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
40 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
41 mode, we change to the source directory, also set $ac_pwd so we
42 do not go back to the build tree for the next config subdir.
43 * tests/torture.at (Deep Package): Extend test to contain two
44 config subdirs on the top level.
46 Fix parallel `maintainer-check'.
47 * Makefile.am (maintainer-check-tests): Depend on `all'.
48 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
49 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
51 (maintainer-check): Serialize the testsuite runs.
53 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
54 in feature string for --enable/--with. Convert to underscore
57 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
58 `install -c file1 file2 dir' works.
59 * doc/autoconf.texi (Particular Programs): Document this.
62 2008-01-21 Eric Blake <ebb9@byu.net>
64 Improve documentation about default include directives.
65 * doc/autoconf.texi (Generic Headers, Generic Declarations)
66 (Generic Structures, Generic Types)
67 (Generic Compiler Characteristics): Add links to
69 Reported by Reuben Thomas.
71 2008-01-15 Eric Blake <ebb9@byu.net>
73 * lib/m4sugar/m4sugar.m4 (m4_qlen): Use fewer macros.
75 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
77 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
78 check_SCRIPTS. Building the wrappers for `all' allows help2man
79 to use them for the manpages.
80 Report by Benoit Sigoure.
82 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
84 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
86 Fix some write failure cases in Autotest.
87 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
88 upon write failures for --help, --version, --list.
89 Guard against write failures for intermediate created scripts.
90 <at_func_create_debugging_script>: Do not make the debugging
91 script executable if it is not complete.
93 2007-12-12 Eric Blake <ebb9@byu.net>
95 Fix thinko in earlier patch - m4_join isn't defined yet.
96 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
97 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
98 (m4_require): Use m4_do, not m4_join.
100 Fix some whitespace tests on cygwin.
101 * tests/tools.at (autom4te and whitespace in file names): Restore
102 font-lock. Create $TMPDIR before it might be used.
104 Fix spurious testsuite failure with M4 1.4.11.
105 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
108 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
109 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
110 (m4_require): Avoid extra macro calls.
112 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
114 * tests/torture.at (srcdir): Fix quoting.
116 Do not pass top_srcdir to configure scripts in testsuite.
117 * tests/autotest.at (srcdir propagation): Copy install-sh to
119 (my only test): Drop setting of `top_srcdir'.
120 * tests/base.at (Input/Output): Likewise.
121 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
122 config.guess, and config.sub to test source tree.
123 Drop AC_CONFIG_AUX_DIR setting.
124 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
125 * tests/torture.at (Substitute a 2000-byte string): Drop
126 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
127 (Substitute a newline, datarootdir workaround): Likewise.
128 (Define a newline): Adjust for linenumber changes in configure.ac.
129 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
131 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
132 if `pwd` contains whitespace.
134 Quote $abs_top_srcdir in tests.
135 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
136 * tests/tools.at (Syntax of the shell scripts): Likewise.
138 * tests/m4sh.at (LINENO): Quote $0.
140 Fix testsuite program wrapper for whitespace in `pwd`.
141 The problem here is that the usual mantra is that command
142 variables can contain arguments, thus we cannot just escape
143 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
144 $top_builddir/tests directory early in $PATH, so that the
145 wrappers are found by their plain name.
146 * tests/wrapper.as: Put $testdir early in $PATH.
147 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
149 Proper config.status --file/--header and $srcdir escaping.
150 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
151 characters in $ac_file_inputs.
152 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
154 * tests/torture.at (datarootdir workaround): Adjust.
155 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
157 Fix Autotest for whitespace in `pwd`.
158 * lib/autotest/general.m4 (AT_INIT)
159 <at_func_create_debugging_script, Driver Loop>:
161 * tests/autotest.at (whitespace in absolute testdir): New test.
163 * lib/autom4te.in: Quote @datadir@.
165 Proper file name escaping in Autoconf programs and Perl modules.
166 This includes escaping of characters special to the shell
167 as well as special to Perl, e.g., leading `<' or `>'.
168 For example, when $file starts with `>', `open ">$file"'
169 wrongly tries to append to a different file.
170 * bin/autoconf.as: Fix quoting for autom4te options.
171 * lib/Autom4te/General.pm (shell_quote): New function, taken
172 from coreutils, written by Jim Meyering.
174 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
176 * bin/autoreconf.in (parse_args): Likewise.
177 * bin/autoscan.in (main): Likewise.
178 * bin/autoupdate.in (main): Likewise.
179 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
180 * bin/ifnames.in: Likewise, XFile usage fixes.
181 * tests/tools.at (autom4te and whitespace in file names): Extend
182 test. Test twice, with special characters allowed on w32, and the
183 rest. Test leading and trailing whitespace, for `open_quote'.
184 (autotools and whitespace in file names): New, analogous test.
185 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
186 by Russ Allbery and Eric Blake.
189 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
190 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
191 * lib/Autom4te/FileUtils.pm (open_quote): New function.
192 (update_file, contents): Use it.
194 * Makefile.am (autom4te-update): Rewrite for git.
196 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
198 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
201 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
202 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
204 2007-12-04 Eric Blake <ebb9@byu.net>
206 Manually resync with gnulib, since 'make cvs-update' no longer works.
207 * build-aux/config.guess: New upstream version.
208 * build-aux/config.sub: Likewise.
210 When using older automake, don't downgrade build-aux/texinfo.tex.
211 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
212 * doc/Makefile.am (TEXINFO_TEX): Add.
214 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
216 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
217 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
218 #undef as this runs afoul of our new way of creating config.h.
219 Problem reported by Jim Meyering in
220 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
222 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
224 Fix autom4te for unusual characters in input file names.
225 * bin/autom4te.in (files_to_options): Quote active characters
227 * tests/tools.at (autom4te and white space in file names):
230 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
231 Document that Tru64 awk always splits $0.
233 2007-11-24 Stepan Kasal <kasal@ucw.cz>
235 * lib/autotest/general.m4 (AT_INIT): Do not extract the
236 `#AT_STOP_...' line at the end of each test.
238 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
240 * lib/autotest/general.m4 (AT_INIT): For awk line number
241 extraction script, ensure `$at_group' has a defined value
242 even for the empty set, and properly quote its usage inside
245 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
247 * doc/autoconf.texi (Shell Functions): New chapter. Document
248 IRIX sh $0 issue in functions, move content from ...
249 (Portable Shell): ... here.
250 (Shell Script Compiler): Note that shell functions are not
251 totally unportable any more.
253 2007-11-22 Stepan Kasal <kasal@ucw.cz>
254 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
256 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
257 extracting the line numbers of the last needed test.
259 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
261 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
264 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
266 Fix IRIX testsuite debugging failures: $0 in functions.
267 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
268 Do not use $0 inside a function, as IRIX sh will set that to the
269 function name rather than the script invocation name.
271 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
272 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
274 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
275 to extract test scripts.
276 (AT_INIT): Extract and cache test script line numbers.
278 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
280 * lib/autotest/general.m4: Revert 2007-11-15 patch and
281 subsequent fixups; the awk -> here-document conversion trashes
282 performance too much with AIX sh.
284 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
286 * tests/local.at: Do not test m4, perl with AT_TESTED.
288 Diagnose and guard against write errors dealing with config.status.
289 The general idea is this: all write failures from `configure'
290 writing `config.status' are indicated by $ac_write_error, which
291 is only checked at the end. This is safe because config.status
292 code is not executed before the file is complete. Other write
293 failures, be they inside config.status, or in sub shell/awk
294 scripts spawned from configure or config.status, typically need
295 earlier checking, as their results are used right afterwards.
296 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
297 before writing config.status, check afterwards.
298 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
299 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
300 Set `ac_write_error' for write failures to config.status. Barf
301 upon write failures to temporary files.
302 Adjust note about closing and reopening the here-document.
303 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
304 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
305 reopening the here-document.
306 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
307 Ensure `ac_write_error' does not escape into config.status.
308 Also, add a couple of code paths not yet exercised in the test
309 suite: a config file with input from stdin, and a config header
311 Suggestion for catching write errors by Bruno Haible.
313 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
315 Avoid error with Tru64 awk and testsuite lines with many words.
316 * lib/autotest/general.m4 (AT_INIT): In the awk script that
317 reads the testsuite, set the field separator to an unusual value,
318 in order to not run over the limit of 199 fields. Tru64 4.0D awk
319 even splits the input if $i, i>0, was never accessed in the script.
321 Revert 2007-10-17 change.
322 * TODO: Multiline args in config files and headers mean something
323 different and are not fixed, see
324 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
325 Report by Stepan Kasal.
327 * doc/autoconf.texi (Generic Programs): Fix typo.
329 2007-11-16 Stepan Kasal <kasal@ucw.cz>
331 AC_*_TOOL does not canonicalize the prefix
332 * doc/autoconf.texi (Generic Programs): Do not say that
333 the *_TOOL macros canonicalize, they simply use the `host_alias'.
335 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
337 Diagnose write errors in config.status instantiations.
338 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
339 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
341 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
342 Extend test to also check for some write error failures, using...
343 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
344 Report by Bruno Haible.
347 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
349 (_AT_CHECK): Use less indentation, to save space.
351 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
353 Add witness macro for @top_build_prefix@ substitution.
354 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
355 (_AC_OUTPUT_FILE): Mention it here.
357 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
358 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
360 * lib/autotest/general.m4 (at_func_test): Remove.
361 (AT_INIT): Pre-extract test groups into separate files.
362 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
363 Remove at-test-source files together with the $at_group_dir.
364 * tests/autotest.at (Long test source lines): New test.
366 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
368 Shell functions and variables may share a namespace.
369 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
372 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
374 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
377 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
379 * lib/autoconf/status.m4: Fix a couple of comment typos.
381 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
383 2007-11-13 Jim Meyering <meyering@redhat.com>
385 Clean up the rule to create "expr".
386 * tests/Makefile.am (expr): Don't redirect directly to target.
387 Redirect just once, not for each echo statement.
388 Use $@, not literal "expr".
390 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
392 Don't worry about preprocessor when testing long long.
393 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
394 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
395 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
396 These no longer check for preprocessor flaws.
397 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
398 Do not check for preprocessor flaws.
400 2007-11-13 Jim Meyering <meyering@redhat.com>
402 Adapt dependencies, now that a version change doesn't modify configure.ac
403 * GNUmakefile: Remove "make clean" kludge.
404 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
406 Don't redirect directly to target.
407 Use $@, not literal "version.m4".
409 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
411 * doc/autoconf.texi (Making testsuite Scripts): Document
412 ":;{" shorthand as in previous patch.
414 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
416 * doc/autoconf.texi (Limitations of Builtins): Document problem
417 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
419 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
421 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
423 2007-11-12 Jim Meyering <meyering@redhat.com>
425 Add more non-srcdir build support.
426 * GNUmakefile (dummy): Split a long line.
427 Add -v option to autoreconf invocation.
429 Remove the autoreconf-provided INSTALL, so that we regenerate it.
430 * GNUmakefile (dummy): Remove INSTALL.
432 Remove racy commands to build scripts in bin/ and tests/.
433 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
434 are guaranteed to be built, remove the rules that tried to build
435 them. Before, with a parallel build, these rules could lead to
436 two processes writing tests/wrapper.in concurrently.
438 Build in man/ only *after* building in bin/ and tests/.
439 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
440 in both bin/ and tests/.
442 Accommodate non-srcdir build-from-checkout.
443 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
444 Use git's --git-dir=$srcdir/.git option.
445 Add quotes, in case tarball_version_file contains shell meta-characters.
446 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
447 * configure.ac: Pass "." to git-version-gen.
449 Avoid spurious test failures due to version skew.
450 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
452 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
454 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
455 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
456 Remove conftest.dSYM directory.
457 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
458 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
459 Remove `conftest.*' recursively.
460 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
461 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
463 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
465 Report and analysis by Jeff Squyres and Peter O'Gorman.
467 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
469 Fix typos in variable names.
470 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
472 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
474 Document that $((expression)) is not portable.
475 * doc/autoconf.texi (Shell Substitutions): Here.
477 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
479 Ignore configure --help* errors due to LINENO-impaired shells.
480 * tests/torture.at (Configuring subdirectories, Deep Package):
481 In the --help* tests in read-only trees, make `.' temporarily
482 writable again for the `stderr' file, and ignore errors due to
483 the attempt to write configure.lineno.
484 Report by Patrick Welche.
486 2007-11-10 Jim Meyering <meyering@redhat.com>
488 Generate package.m4 in build-dir, not srcdir.
489 * tests/Makefile.am (package.m4): Adjust target.
490 Don't redirect directly to $@.
491 (CLEANFILES): Add package.m4.
492 ($(TESTSUITE)): Depend on just-built package.m4, not the one
494 When running $(AUTOTEST), search "." before searching $(srcdir).
496 Avoid a race condition that would make parallel "distclean" fail.
497 * tests/Makefile.am (distclean-generic): Replace the default,
498 automake-provided rule with an identical one, but with an additional
499 dependency on distclean-local. Simply adding the dependency would
500 cause automake not to emit the rule at all.
501 * BUGS: Building with -jN works, now.
503 Distribute git-version-gen.
504 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
505 since GNUmakefile is distributed, and requires it for dist* rules.
507 Remove two more generated files from version control.
508 * INSTALL: Remove generated file.
509 * lib/autoscan/autoscan.list: Remove generated file.
511 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
513 * GNUmakefile (PATH): Remove stray apostrophes; they become
514 part of PATH, which isn't wanted here.
516 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
518 New config files output variable `top_build_prefix'.
519 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
521 * doc/autoconf.texi (Preset Output Variables): Document it.

638 Make inter-release --version output more useful.
640 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
641 which indicates that it is built using the 19th change set

1954 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
1955 works but the latter doesn't, then it's a valid type.

1958 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1959 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

2046 extra argument ACTION-IF-UNIVERSAL.
2047 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
2048 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
2049 Reindent for sanity's sake.
2051 2007-02-24 Eric Blake <ebb9@byu.net>
2053 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

2059 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2061 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
2062 status of rm so we know when it failed.
2063 If cleaning of test dir failed before running the test, warn.
2064 Output the line separator in verbose mode before the warning
2065 to make clear the warning belongs to the following test.
2067 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
2069 * doc/autoconf.texi (Parentheses): Mention problem with (( in

2076 errors introduced in last change.
2078 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2080 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to

2084 with traditional Awk and begin.
2085 * tests/torture.at (Limitations of Builtins): Document the problem
2086 with Bash 2.03 printf.

2090 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
2092 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
2093 input from /dev/null in awk test, so even Solaris /usr/bin/awk
2094 will not wait for input with a script containing only a BEGIN
2097 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2099 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version

2128 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2130 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2131 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2132 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2133 substitution will still be done by the special code.
2134 Report by Jim Meyering.
2136 * doc/autoconf.texi (File System Conventions): Mention that
2137 $PATH_SEPARATOR is for the build system only.

2147 * tests/torture.at (Substitute and define special characters):
2148 Test all 8 bit non-NUL characters.
2149 Report against Automake by Patrick Welche.
2151 2007-01-15 Stepan Kasal <kasal@ucw.cz>
2153 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
2155 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2157 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2158 early on the reader side, drop stderr of the input to avoid
2159 `broken pipe' error output; this may happen even with shell
2160 builtin `echo' of some bash versions. Reports by Ian Macdonald
2161 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2163 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2165 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
2166 separate items of `ac_user_opts', to avoid long lines.
2167 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
2169 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2173 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
2175 Fix some wording problems noted by Paolo Bonzini in:
2176 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2177 * doc/autoconf.texi (Signed Overflow Examples): Give more
2178 discussion about the allow_superuser_privileges example,
2179 and change it a bit to make things clearer.
2180 (Optimization and Wraparound): Clarify whether the compiler
2181 will generate an infinite loop for the example derived from
2182 Autoconf's mktime test.
2183 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2184 Also, clarify unsigned multiplication overflow.
2186 2007-01-04 Eric Blake <ebb9@byu.net>
2188 * bin/Makefile.am (RELEASE_YEAR): New macro.
2189 (edit): Use it to supply correct copyright year to scripts.
2190 * bin/autoconf.as (version): Use it.
2191 * bin/autoheader.in ($version): Likewise.
2192 * bin/autom4te.in ($version): Likewise.
2193 * bin/autoreconf.in ($version): Likewise.
2194 * bin/autoscan.in ($version): Likewise.
2195 * bin/autoupdate.in ($version): Likewise.
2196 * bin/ifnames.in ($version): Likewise.
2198 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2200 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2201 feedback. The most important changes document what happens when
2202 you convert an out-of-range value to a signed integer type, and
2203 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2206 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2207 rewrite, taking notions from the recent discussion on the gcc and
2208 autoconf mailing lists; please see
2209 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2210 and follow the many links.
2211 (Integer Overflow Basics, Signed Overflow Examples):
2212 (Optimization and Wraparound, Signed Overflow Advice):
2213 (Signed Integer Division): New sections.
2215 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2217 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2218 preprocessor macro arguments in traced name.
2219 * doc/autoconf.texi (Defining symbols): Document longstanding
2220 support for AC_DEFINE-ing macros with arguments, and document
2221 behavior when the same variable has multiple AC_DEFINEs.
2222 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2223 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2224 macros directly, giving much shorter and simpler code.
2226 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2228 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2229 space before "$ac_configure_args" to prevent a 'config.status
2230 --recheck' failure if ac_configure_args doesn't contain a leading
2231 space. This works around a problem with the XEmacs configure.ac,
2232 which uses the (undocumented) ac_configure_args variable
2233 inconsistently with Autoconf.
2235 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2237 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2238 Include <limits.h>, and use its INT_MAX to rewrite the
2239 j loop so that it does not overflow 'int'. Problem reported by
2241 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2242 Play it safe by shifting left by 1 rather than multiplying by 2,
2243 as GCC is less likely to optimize this away when the value
2244 is signed (when it assumes overflow leads to undefined behavior).
2245 Also, don't assume time_t uses two's complement.
2247 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2249 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2250 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2251 dumps core on it. Report by Tim Rice.
2253 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2255 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2256 --disable-option-checking to --help output even when
2257 AC_PRESERVE_HELP_ORDER is not used.
2258 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2259 --with argument, rather than argument with [-.] replaced by
2261 * NEWS: Fix typo in previous change; the news was in the
2264 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2266 * NEWS: Warnings are now generated by default for unknown
2267 --enable-* and --with-* options.
2268 * doc/autoconf.texi (Option Checking): Renamed from
2269 (Configure Option Checking). Tighten up the wording a bit.
2270 (External Software, Package Options): Cross-reference to Option
2271 Checking, and use this to shorten our section.
2272 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2273 "$x" to test "x$foo" != x.
2274 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2275 Don't warn if $enable_option_checking is "no".
2276 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2277 ac_unrecognized_opts to the empty string.
2278 Don't echo the unrecognized opts, as this might mishandle
2279 backslashes or leading -.
2280 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2281 usage next to the other --disable-FEATURE options in the
2284 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2286 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2287 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2288 Print warning for unrecognized --with and --enable options
2289 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2290 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2291 Disable option checking when subdirs are configured.
2292 (AC_OUTPUT): If warnings are enabled, print warning about
2293 unrecognized --with and --enable options at the end of
2294 the configure output (as well as at the beginning).
2295 * doc/autoconf.texi (Option Checking): New node.
2296 Document new option warning functionality.
2298 2006-12-16 Eric Blake <ebb9@byu.net>
2300 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2301 * NEWS: Start news for current version.
2303 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2305 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2306 Define HAVE_GETMNTENT to 1, not to the empty string.
2307 Problem originally reported by Jochen Friedrich in
2308 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2310 This change prompted by a problem report by Andrey Simonenko in
2311 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2312 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2313 object-like macros only, in the traditional portable character
2315 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2316 Warn about attempts to define things that are not identifiers.
2317 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2318 awful hack that AC_DEFINEd macro names containing parentheses.
2320 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2322 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2323 too drastic, even if Texinfo in theory requires it for info mode.
2325 (config.status Invocation): Renamed back from Recreating a
2327 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2328 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2330 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2332 * NEWS: Version 2.61a.
2334 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2335 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2337 * NEWS: Document changes with echo and printf, and the lack
2338 of limits on the total size of multi-line values of substituted
2339 variables, and the AC_FUNC_FSEEKO fix.
2341 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2343 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2344 Writing configure.ac.
2345 (Autoconf Input Layout): Renamed from configure.ac Layout.
2346 (Recreating a Configuration): Renamed from config.status Invocation.
2347 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2348 (acconfig Header): Renamed from acconfig.h.
2349 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2350 (Writing Testsuites): Renamed from Writing testsuite.at.
2351 (Autom4te Cache): Renamed from autom4te.cache.
2353 * BUGS: Remove mention of VPATH problem, since it's now documented
2354 not to be a bug in the Autoconf build procedure itself, but rather
2355 a problem with the proprietary `make' programs.
2357 * doc/autoconf.texi (Build Directories): Add a cross reference
2360 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2361 * doc/standards.texi: Sync from gnulib.
2363 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2364 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2365 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2366 generated automatically.
2368 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2370 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2371 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2372 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2374 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2376 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2377 `CEOF$ac_eof' special marker, the awk script cannot contain a
2378 line matching `^CEOF', so this is not needed any more.
2379 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2380 special marker in the test.
2382 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2384 * tests/tools.at (autom4te preselections): Use `find -newer';
2385 remove one of the sleeps.
2387 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2388 more readable, using ...
2389 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2391 * doc/autoconf.texi (autoheader Invocation): Do not double-
2392 quote the parameter of `AH_BOTTOM' in the example.
2394 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2396 * doc/autoconf.texi (Configuration Headers): Remove the
2397 example with multiple input files.
2398 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2399 multiple input files.
2401 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2403 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2404 creating the awk substitution script, handle one input line at a
2405 time, so that the maximum length of a substituted (multi-line)
2406 value is not limited by the size of the sed pattern space.
2407 The trade-off is a slightly repetitive sed script.
2408 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2409 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2410 * tests/torture.at (Substitute a 2000-byte string): Increase the
2411 test with several long lines, they should not be caught by sed
2414 * tests/tools.at (autom4te preselections): New test, to flag
2415 entries missing from autom4te.cfg.
2416 Report by David Byron <dbyron@hheld.com>.
2418 * tests/torture.at (Substitute a 2000-byte string): Actually use
2419 AC_PROG_AWK, so the last change works as intended.
2420 (Substitute and define special characters): Likewise.
2421 (Substitute a newline): Likewise.
2423 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2424 instead of `awk' consistently.
2425 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2426 * tests/torture.at (Torturing config.status): Test both the
2427 result of AC_PROG_AWK and plain awk.
2428 (Substitute a 2000-byte string): Likewise.
2429 (Substitute and define special characters): Likewise.
2430 (Substitute a newline): Likewise.
2432 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2434 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2435 can be assigned to a function pointer. Problem reported by
2436 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2437 part of a patch by Ralf Wildenhues in that same bug report.
2439 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2441 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2442 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2444 2006-12-01 Eric Blake <ebb9@byu.net>
2446 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2447 cross-compiling from cygwin to mingw.
2448 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2449 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2450 to lib/autoconf/c.m4.
2452 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2454 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
2455 string for more reliable failure. Wrap the entire test that
2456 causes the broken Solaris printf to dump core, in a subshell,
2457 so the segmentation fault message is reliably suppressed.
2458 Fix shell expansion errors by using /usr/ucb/echo always;
2459 avoid an error on systems without it by another subshell.
2460 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2461 subshell-$as_echo to `as_echo', for better error message.
2463 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2465 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2466 `BASH_SOURCE' contain a newline, set them to empty, as they may
2469 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2471 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2472 years and is too hard to maintain now. The last straw was
2473 reported by Jerker Baeck in
2474 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2475 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2476 * doc/autoconf.texi (Particular Functions): Move
2477 AC_FUNC_SETVBUF_REVERSED from here...
2478 (Obsolete Macros): ... to here. Say that it does nothing now.
2479 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2480 Turn into (almost) a no-op.
2482 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2484 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2485 These macros are obsolescent and new applications shouldn't need them.
2486 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2487 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
2488 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):

2518 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2519 in the sed script that mangles the awk script: delete up to the
2520 first exclamation mark only.
2521 * tests/torture.at (Substitute and define special characters):
2524 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2526 Rewrite config files generation: avoid quadratic growth in
2527 the number of substituted variables by using awk instead of sed
2528 for the bulk of the substitutions.
2529 * NEWS: Mention this.
2530 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2531 forbidden in the output (and thus input) file.
2532 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2533 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2534 generate just one large awk script for substitutions,
2535 eliminating much of the earlier complexity, while adding some
2536 new complexity. Only expand the substitution templates at
2537 configure time, for smaller configure script size. If
2538 _AC_SUBST_FILES are used, test 'awk' for working getline support
2539 at config.status time. If absent, interpolate through the
2540 shell. The awk script was written with much help
2541 from Paolo Bonzini and Paul Eggert.

2548 substitute a line with 1000 words, and a variable with several
2550 (Substitute and define special characters): Test awk special
2551 characters, and put substitution input strings `@foo@' in the
2552 output, to test that no recursion happens; test several other
2553 combinations from Paolo Bonzini.
2555 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2557 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2558 that replaced echo with AS_ECHO where this wasn't necessary.
2559 Problem reportd by Ralf Wildenhues.
2560 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2561 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2562 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2564 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2570 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2571 that traditional Awk lacks 3-arg "split". It has it.
2572 Mention that FS must be a single character, and a few other
2573 99-byte limits of traditional Awk.
2574 Mention that if (i in a) doesn't work with traditional Awk.

2582 (Single-quote-newline-BS-newline in command):
2583 Use printf '%s\n' instead of echo, for portability to hosts
2584 where echo interprets backslashes. This will break on hosts
2585 that lack printf, but for now let's assume all such hosts
2586 are dead (if not, we should get reports of test failures).
2588 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2590 'echo' has some portability problems, when given a first argument
2591 with a leading '-', or when given any argument containing '\'.

2744 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
2747 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2749 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2750 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2751 Imported from a similar patch to gnulib by Bruno Haible.

2772 and Stepan Kasal <kasal@ucw.cz>
2774 Handle special characters in test case titles correctly.
2775 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
2777 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
2778 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
2779 argument. Extend to check titles printed by ./micro-suite and
2780 ./micro-suite -l and the title in micro-suite.log.
2781 (Backquote in a test title,
2782 Single-quote in a test title,
2783 Double-quote in a test title): Don't expect failure anymore.
2784 (Backslash in a test title): Put a non-whitespace character after the
2785 backslash so that Bourne shells might actually see it as an escape
2787 (Brackets in a test title,

2796 * tests/torture.at (#define header templates): M4-quote this title in
2797 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2798 The visible effect was a stray [] in the testsuite output.
2800 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2802 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

2805 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2807 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2808 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2809 5363) simply issues a warning when dividing by zero at compile
2810 time. Problem reported by Elias Pipping.
2812 2006-10-26 Eric Blake <ebb9@byu.net>
2815 * doc/autoconf.texi (Evaluation Macros): Improve the example to
2816 show effect on macros that expand with commas.

2843 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2844 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2845 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2846 reported by Nelson H. F. Beebe for Coreutils 6.4.
2848 * tests/tools.at (autoconf --trace: user macros): Remove test
2849 for tracing multiline macros, since m4 1.4.7a uses a different
2850 way to number lines. Problem reported by Ralf Wildenhues.
2852 2006-10-24 Stepan Kasal <kasal@ucw.cz>

2926 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2928 (Imported from Automake.)
2929 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2930 which incorrectly sets the mode of an existing destination
2931 directory. In some cases the unpatched install-sh could do the
2932 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2933 system. We hope this is rare in practice, but it's clearly worth
2934 fixing. Problem reported by Alex Unleashed in
2935 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2936 Also, don't bother to check for -m bugs unless we're using -m;
2937 suggested by Stepan Kasal.

2996 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

3009 the NonStop platform.
3010 * doc/autoconf.texi (Posix Variants): Likewise.
3011 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
3013 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
3014 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
3015 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
3016 Use a better substitute, by inspecting the output of "ls"
3017 rather than just using ":".
3018 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3019 rather than AS_EXECUTABLE_P, since we needn't worry about
3020 non-regular files here.
3022 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3023 due to configuration hassles with this. See Tonya Underwood's report
3024 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

3048 comment about ac_cpp_err; it was incorrect, and anyway
3049 ac_cpp_err is being removed below.
3050 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3051 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3052 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3054 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3055 with werror_flag and conftest.err and so forth. This is more
3056 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3057 and anyway the user shouldn't normally want to see this gorp logged.
3058 Problem reported by Ralf Wildenhues.
3059 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3060 empty, not 'no', since the rest of the code uses 'test -z'.
3062 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
3064 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3065 Use a single call to AC_DO_TOKENS rather than multiple, for
3067 (_AC_LINK_IFELSE): Test that resulting file is executable.
3068 Problem reported by mwoehlke in
3069 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
3071 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
3072 than creating a file to use with test -x; this is much faster.
3074 2006-10-02 Bruno Haible <bruno@clisp.org>
3076 * lib/autom4te.in (Automake-preselections): Add
3077 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

3086 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

3088 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
3089 Set cache var to 'unknown' (not 'no') if leaving the macro unset
3090 still doesn't let the program compile.

3094 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
3095 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
3096 include it, without including anything else.

3104 `error.h', and include it, for a `error_at_line' prototype.
3105 Use a nonempty format string in the link test.
3106 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
3107 for a declaration of wait3.

3112 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
3113 can apply to constants too, and that it checks for macro defns.
3114 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
3115 and simply cast the identifier to void. This handles structure
3116 values. Problem reported by Ralf Wildenhues.

3206 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

3210 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
3211 7.1.4 /usr/bin/posix/sh described by Tim Rice in
3212 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.

3331 broken lex libraries like native ia64-hp-hpux11.22; see
3332 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

3460 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
3461 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
3462 -Wundef -Werror". Problem reported by David Fang in
3463 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

3486 problems with arg script text that doesn't end in newline, and
3487 with '-e a...'. Problems reported by Ralf Wildenhues.
3489 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
3491 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
3492 check for libXt by a check for libX11.
3494 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3499 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3501 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status

3505 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
3507 Fix test suite failures reported by Pierre in
3508 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.

3510 the compiler created a file "b.out" when it didn't create anything
3512 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
3513 Discard stderr too, when invoking the test script.

3518 in the restoring of the werror flag.
3520 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
3522 * doc/autoconf.texi (Volatile Objects): Be even a little
3523 less skeptical about "volatile", after discussion with
3524 Bruno Haible on bug-gnulib.
3525 (Limitations of Usual Tools): Warn about sed stripping
3526 leading white space from text. From Bruno Haible.
3528 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3530 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
3531 compiler complains about it, even if things works after the
3532 complaint. Problem reported by Peter O'Gorman.
3534 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
3535 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3536 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3538 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3540 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
3541 after -R regardless of host. Patrick Welche reports that this

3552 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3553 under AC_C_VOLATILE.
3554 (Volatile Objects): Be a little less skeptical about what
3555 "volatile" means. Derived from thoughts by Ben Pfaff in
3556 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3558 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3560 * doc/autoconf.texi: Fix some typos.
3562 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3564 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3565 more globally, since the 2006-06-30 patch didn't suffice. Problem
3566 reported by Keith Marshall. Also, don't bother with builddir2,
3567 since it shouldn't be needed any more.
3569 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3571 * doc/autoconf.texi (Generic compiler characteristics):
3572 Document AC_COMPUTE_INT. Fix wrong statements on Default

3586 * NEWS: Document previous change.
3588 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3590 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3591 Require that long long int be at least 64 bits wide. C99 requires
3592 this and enough programs depend on it so we should check for it.
3593 Bruno Haible reports in
3594 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3595 that long long int is 32 bits wide with some nonstandard compilers.
3596 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3598 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3600 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3601 to a nonexistent file, so that we don't have to worry about
3602 a local site configuration that doesn't use /usr/local.
3603 Problem reported by Keith Marshall in
3604 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3606 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3608 * doc/autoconf.texi: Be more consistent about using @acronym with
3609 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3610 quite right (it talked about "OSF/Tru64", even though the
3611 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3612 and it even mentioned "OSF 4"!) and at this point there's little
3613 reason to talk about OSF any more, since it died in 1994.
3614 (Specific Compiler Characteristics): Simplify example of
3615 negative-size array.
3616 (File Descriptors): Reorder to make the text flow better.
3617 Remove joke about "appreciate the various levels"; I didn't get it.
3618 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3619 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3620 (File Descriptors, Limitations of Usual Tools):
3621 Tone down the advice against renaming or removing open files.
3622 (Limitations of Usual Tools): Add a new section, on 'rm'.
3624 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3626 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3627 -lXt in LIBS, idea from Karsten Hopp; this was due since
3630 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3631 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3632 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3633 (which belong to Xt, not X itself). See Debian bug 327655.
3635 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3637 * configure.ac (AC_INIT): Bump to 2.60a.
3640 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3644 * configure.ac, NEWS: Update.
3646 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3648 * config/texinfo.tex: Sync from upstream.
3650 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3651 quadrigraph correctly in traces.
3653 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3656 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3657 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3659 * doc/autoconf.texi (Changed Directory Variables): New node,
3660 to document the whole `datarootdir' business a bit better.
3662 * tests/torture.at (datarootdir workaround): Extend test.
3663 Prompted by report by Alexandre Julliard.
3665 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3667 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3668 when using default mode of IBM C 6 for AIX. Problem and two-line
3669 fix reported by Larry Jones.
3671 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3673 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3674 about literal '${datarootdir}' if a definition is found in the
3677 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3679 * NEWS: Use "M4" rather than "m4" when appropriate.
3680 Problem reported by Eric Blake.
3681 * doc/autoconf.texi: Likewise.
3682 Use @acronym around BSD, GCC, and GNU when appropriate.
3683 (Why GNU M4): Renamed from "Why GNU m4".
3684 (Redefined M4 Macros): Mention that Posix
3685 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3686 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3689 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3691 * bin/autom4te.in (handle_output): Do not forbid the empty
3693 * tests/tools.at (autoconf: the empty token): New test.
3695 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3697 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3698 calls, so that we do not care whether they are LIFO or FIFO;
3699 in the m4_wrap, do not check which diversion is the topmost
3700 one, just check that the stack is balanced at the end.
3701 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3702 base diversion forever--pop the previous diversion before
3703 opening the new one; consequently, remove the m4_wrap call.
3704 * lib/autotest/general.m4 (AT_INIT): Likewise.
3705 * tests/m4sugar.at: Do not use
3706 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3708 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3709 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3711 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3712 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3713 Rework example of m4wrap token-pasting trouble so that it doesn't
3714 care whether it's LIFO or FIFO.
3715 Fix some "contrary to"s that are awkward in English.
3717 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3719 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3720 to `yes' instead of `int$1_t' if the type is found, for more
3721 consistent configure output (where $1 is the number of bits).
3722 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3723 Suggested by Bruno Haible.
3725 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3726 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3727 with system headers. Report by Bruno Haible.
3729 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3731 * config/config.guess, config/config.sub: Sync from upstream.
3733 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3734 in order to avoid picking up an older installed frozen m4sh.m4f.
3735 Besides an outdated shell startup, this could have been created
3736 by an earlier M4 version with incompatible frozen file format.
3738 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3740 * README: Recommend m4 1.4.4 instead of 1.4.3..
3741 * doc/autoconf.texi: Likewise.
3742 (Special Chars in Names): Say that $(.FOO) is portable, as
3743 suggested by Stepan Kasal.
3744 (Installation Directory Variables, Build Directories):
3745 (Automatic Remaking, Subdirectories, Fortran Compiler):
3746 (Making testsuite Scripts, Defining Directories):
3747 Quote variable usages better.
3748 (Making testsuite Scripts): Add clean-local rule to makefile
3749 snippet, by Eric Blake.
3750 (Installation Directory Variables): Fix table item font.
3751 Reword slightly to clarify. Generalize advice about
3752 not using special characters to include all file-related
3753 vars, not just VPATH.
3754 (Special Chars in Variables): Warn about special characters in
3756 (Assignments): Clarify default-value example as suggested by
3758 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3759 (Special Shell Variables): Note leading ./ or ../, as suggested
3761 (Limitations of Builtins): Under cd, warn about CDPATH.
3762 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3765 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3767 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3768 `@var', for texi2html.
3769 (Systemology): Some more word wrapping, for DVI output.
3770 (autom4te Invocation): The short option for `--melt' is `-M',
3773 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3775 * doc/autoconf.texi: More formatting and English tweaks,
3776 many suggested by Ralf Wildenhues.
3777 Reword to avoid "@code{...}'s" and the like, since it's ugly
3778 with Emacs info mode. discontents -> woes.
3779 Put a few "will"s back. time stamp -> timestamp.
3780 side-effect -> side effect.
3782 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3784 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3785 Warn about $@ not persisting. Problem reported by Julien Danjou in
3786 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3787 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3788 Mention other special chars, too.
3790 2006-06-14 Eric Blake <ebb9@byu.net>
3792 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3794 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3796 * doc/autoconf.texi: Some systematic minor improvements, as
3797 follows. Use "makefile" when talking about makefiles
3798 generally (which might be named "makefile" or "Makefile" or even
3799 "foo.mk"), "Makefile" when talking about a specific makefile
3800 called "Makefile". This unclutters the text from weird quotes
3801 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3802 values" rather than "@var{foo}s" and similar constructs containing
3803 "}s". Use "Make rules" rather than "Makefile rules". Minor
3804 English-language improvements. Change the prefix "sub-" to "sub"
3806 Put blank lines around examples more consistently.
3807 Avoid "rather" and "very" as intensifiers.
3808 Avoid "will" as an auxiliary.
3809 (Limitations of Make): Split this node into....
3810 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3811 (Leading _ in Macro Names, Backslash-Newline-Newline):
3812 (Backslash-Newline Comments, Long Lines in Makefiles):
3813 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3814 (obj/ and Make, make -k Status, VPATH and Make):
3815 (VPATH and Double-colon, $< in Explicit Rules):
3816 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3817 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3818 New nodes, resulting from splitup of Limitations of Make.
3819 All cross-references changed. Raise the top node from
3820 a section to a chapter, and all subnodes accordingly.
3821 Redo the introductory wording to match the new organization.
3822 (Installation Directory Variables): Use an example that is
3823 closer to what Autoconf actually does. Mention that VPATH's
3824 value should not contain metacharacters or white space.
3825 (Fortran Compiler): Fix a VPATH bug in an example.
3826 (Leading _ in Macro Names): Mention that this problem is no longer
3827 of practical concern.
3828 (VPATH and Make): Reword the advice to make it clearer
3829 that Autoconf and Automake support VPATH in non-GNU make, but
3830 many packages have bugs in this area.
3831 ($< in Explicit Rules): Refer to Build Directories rather
3832 than using a (non-VPATH-safe) example.
3833 (Automatic Rule Rewriting): Mention the sort of disaster that
3834 can ensue with Solaris-style rule rewriting with VPATH.
3836 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3838 * doc/install.texi (Compilers and Options): Weaken the
3839 suggestion to use GNU make for VPATH builds.
3841 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3842 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3844 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3845 in regular expression.
3847 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3849 * doc/autoconf.texi (Installation Directory Variables):
3850 Drop extra @samp from `@table @samp' item.
3851 (Limitations of Usual Tools): Comment fix.
3852 Do not nest @samp just to point to other table items.
3853 (Writing testsuite.at) <AT_CHECK>: The second argument to
3854 `@dvar' is already @samp'ed.
3855 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3856 do not use @var in the second argument.
3858 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3860 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3861 $as_shell.exe too. Problem reported by Andreas Buening in
3862 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3864 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3866 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3867 `unused variable' compiler warning, for `-Wall -Werror'.
3868 Reported by Jaap Haitsma in
3869 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3871 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3873 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in

3880 2006-06-06 Tim Rice <tim@multitalents.net>.
3882 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3883 "ERROR" only shows up in "make check" output if there is an

3907 * config/texinfo.tex: Sync from upstream.
3909 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3910 seen, invoke libtoolize with `--ltdl' argument.
3911 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3913 Suggested by Eric Blake.
3915 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3917 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
3918 reported by Ralf Wildenhues.

3925 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3927 * doc/autoconf.texi: Modernize some of the references to Solaris.
3929 2006-06-05 Stepan Kasal <kasal@ucw.cz>
3931 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
3932 message issued by AC_REQUIRE.
3933 * tests/m4sugar.at: Check m4_require's error message.
3934 * tests/base.at: Check AC_REQUIRE's error message.
3935 * tests/local.at (AT_CHECK_M4): New macro, almost identical
3937 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
3939 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
3940 `expout' as the last parameter.
3941 * tests/tools.at: Adapt to the above change.
3943 2006-06-04 Stepan Kasal <kasal@ucw.cz>
3945 * doc/autoconf.texi (Limitations of Usual Tools): Correct
3946 information about race-free implementations of mkdir.

3957 * NEWS: GNU make now recommended for VPATH builds.
3958 Mention that some macros are now documented to be obsolescent.
3959 * doc/autoconf.texi:
3960 Prefer "current" to "modern" to describe
3961 currently-used (albeit perhaps old-fashioned) hosts.
3962 Mention which ancient features no longer need to be worried about.
3963 setgid -> set-group-ID
3964 setuid -> set-user-ID (these are the Posix terms)
3965 Fix some misuses of "only".
3966 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
3967 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
3968 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

3975 Mention that these macros are obsolescent.
3976 (Installation Directory Variables): shall -> should
3977 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3978 Mention that it's now safe to use 3 and 4.
3979 (Limitations of Usual Tools): cp -r is now specified by Posix.
3980 Omit longwinded and obsolescent discussion of cp -f.
3981 Modernize discussion of expr, ls.
3982 (Limitations of Make): Modernize discussion of VPATH builds.
3983 Mention $? as a workaround in some cases.
3984 * doc/install.texi (Basic Installation):
3985 Mention "./configure; make; make install" first. Be more
3986 specific about why this file is generic. Remove unnecessary
3987 parens. Remove misleading "only". Remove obsolete advice
3988 about csh. Don't say "configure" takes awhile; say it
3989 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3990 and CC=c99 rather than CC=c89, as these are blessed by current
3991 Posix. Recommend GNU make if doing a VPATH build.
3993 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3995 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3996 examples involving shell prompts.

3999 and Paul Eggert <eggert@cs.ucla.edu>
4001 * doc/autoconf.texi (Here-Documents): Add details about the
4002 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4003 use "here-documents" instead of "here documents".
4005 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4012 anywhere in directory names.
4014 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4016 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4017 about quoting the case statement, just in case.
4018 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4019 was fixed in ksh93g; reported by Ralf Wildenhues.
4021 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4023 * doc/autoconf.texi (System Services): Do not document

4030 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4032 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4033 argument with leading hyphen. Problem reported by Paul Eggert.
4035 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4037 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4038 about quoting ac_try: quote all of it, if any of it seems suspicious.
4039 This means we don't have to worry about ${ or sed any more.
4040 Also, double-quote the case statement, to work around misuses via
4041 underquoting as reported by Ralf Wildenhues in
4042 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4043 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4044 undocumented and dangerous macro.

4056 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4057 since evidently some packages rely on the old, broken behavior.
4058 Problem reported by Ralf Wildenhues in
4059 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4060 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4061 pre-2006-05-26 definitions, but leave in the comments that
4062 these macros are dangerous and should not be used.
4063 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4064 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4065 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4066 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4067 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
4069 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
4071 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
4072 the use of 'tr', since this is our only use of 'tr'.
4074 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4075 and Paul Eggert <eggert@cs.ucla.edu>
4077 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
4078 Don't assume 'grep' works on long lines, since AIX grep doesn't.
4080 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4082 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
4083 the output file in the `${datarootdir}' test.
4085 2005-05-28 Stepan Kasal <kasal@ucw.cz>
4086 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4088 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
4089 mention of `datarootdir' in the input file(s), but literal
4090 `${datarootdir}' in the output file, and we haven't warned yet,
4091 then warn as well: the user may have (erroneously) used
4092 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
4093 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
4094 * tests/torture.at (datarootdir workaround): Extend this test.
4097 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4098 and Paul Eggert <eggert@cs.ucla.edu>
4100 * doc/autoconf.texi (autoheader Invocation): The first argument to
4101 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4102 alternatives and clear up the language a bit.
4104 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4106 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4107 ac_config_guess, ac_config_sub, ac_configure.
4108 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4109 Fix typo that prevented an unnecessary space from being removed.
4110 Problems reported by Ralf Wildenhues in:
4111 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4113 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4115 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4116 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4117 Don't use the term "thread-safe" to talk about mkdir race
4118 conditions, since the problem is more a process than a thread
4119 issue. Problem reported by Stepan Kasal in:
4120 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4121 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4122 the test for 'install' more closely. Look at MKDIR_P first.
4123 Look in the PATH, and at /opt/sfw/bin.
4124 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4125 Don't bother to try mkdir -p, since we already check mkdir --version;
4126 just look at the version number. (There's no easy way to check
4127 for race-free implementations.)
4128 * tests/tools.at (autoconf: subdirectories): Adjust to above
4129 changes, since MKDIR_P now might end in "/mkdir -p".
4131 * doc/autoconf.texi (autoheader Invocation): Mention that the
4132 first arg of AC_DEFINE_UNQUOTED must be a literal.
4133 Problem reported by Ben Pfaff in
4134 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4136 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4137 * doc/autoconf.texi (Special Chars in Variables): New section.
4138 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4139 (Installation Directory Variables): Quote $(datadir) better.
4140 (Limitations of Builtins): Describe some of eval's trickiness.
4142 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4143 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4144 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4145 in front of every arg, not just trailing args. Quote apostrophes.
4146 (_AC_EVAL_ECHO): New macro.
4147 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4148 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4150 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4151 exposed by quoting of eval argument. Put the command on line line
4153 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4154 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4155 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4156 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4157 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4158 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4159 Use eval more safely.
4160 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4161 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4163 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4164 lines, exposed by quoting of eval argument.
4166 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4167 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4169 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4170 initialization of `ac_cv_exeext', do not override it if it was
4171 already set, unless it was set to `no', for compatibility with
4172 Autoconf-2.13, and comment this.
4173 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4174 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4175 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4176 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4177 Document that this test may be overridden by setting
4180 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4182 Revert these two patches:
4184 2006-04-06 Eric Blake <ebb9@byu.net>
4185 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4186 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4189 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4190 Clean up _AC_COMPILER_EXEEXT* macros.
4191 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4192 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4193 ac_file to the name of the default output file and call
4194 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4195 initial `rm' of the candidate files...
4196 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4197 the same list in subsequent `rm' calls, and for the temporary
4198 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4199 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4200 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4201 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4202 no longer needed) by libtool. Make it a cache check.
4203 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4204 copied here by mistake.
4205 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4206 _AC_COMPILER_EXEEXT.
4207 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4208 _AC_COMPILER_OBJEXT directly.
4209 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4211 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4213 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4214 Fix description of how the buggy `sed' works.
4216 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4220 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4221 ENOLCK. Only mention `make -j' when applicable. Only raise
4222 fatal errors when `make -j' is involved. Improve error message.
4224 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4226 * doc/autoconf.texi (Here-Documents): We now know more about
4227 the variable expansion in here documents bug.
4228 Thanks to Tim Rice and Stepan Kasal.
4230 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4231 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4233 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4235 * tests/autotest.at (Multiline command from M4 expansion):
4236 No failure to be expected if the shell quotes newlines in
4237 commands in the `set -x' output. Report by Tim Rice.
4240 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4242 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4243 expansion in the here-documents used by config.status, as that
4244 runs afoul of the Korn shell version M-12/28/93d bug described in
4245 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4246 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4247 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4249 2006-05-23 Jim Meyering <jim@meyering.net>
4251 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4252 Fix typo introduced with 2006-04-02 change. It reversed the sense
4255 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4257 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4258 ac_dB slightly, to save bytes in the script.
4259 Max out at 50 lines, rather than 96; this is more likely
4260 (though not guaranteed) to avoid obscure 'sed' failures.
4262 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4264 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4265 `tr -d -' as bad option argument. Work around this by deleting
4266 an unrelated character.
4267 Report by Tim Rice <tim@multitalents.net>.
4269 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4270 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4271 Stepan Kasal <kasal@ucw.cz>
4273 * doc/autoconf.texi (Particular Programs): Do not promise that
4274 we always prefer the GNU version of the program, and that we
4275 search according to PATH; both rules can have exceptions.
4276 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4277 AC_PROG_SED. Move descriptions of limitations
4278 to the Limitations of Usual Tools section.
4279 (Limitations of Usual Tools) <sed>: Mention script length
4280 limitations with Solaris /usr/ucb/sed.
4281 <grep>: Fix wording for empty alternative. Mention that -c and
4282 -l should not be combined, and that -E and -F should not be
4285 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4286 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4288 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4289 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4291 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4293 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4294 AC_DEFINE is now passed to m4_pattern_allow.
4295 * NEWS: Mention that; likewise for AC_SUBST.
4296 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4297 the parameter to m4_pattern_allow.
4298 * tests/tools.at: Add a check for that.
4300 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4302 * lib/autoconf/status.m4: Fix typos.
4304 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4306 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4307 only the files that this macro generates.
4309 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4311 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4312 the HP-UX sed limitation of 99 commands, labels do not count.
4313 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4315 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4317 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4319 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4320 Import the following fix from coreutils:
4322 2006-01-13 Jim Meyering <jim@meyering.net>
4324 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4325 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4326 not double-quote uses of that variable, to accommodate the rare
4327 case in which getmntent is available in none of the libraries
4328 checked. This happens at least on FreeBSD 5.0.
4330 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4332 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4333 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4334 some other programs unwisely rely on these undocumented vars.
4335 But put in warning comments about them.
4336 Problem reported by Ralf Wildenhues in
4337 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4338 * NEWS: Document that these variables are intended to go away.
4340 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4342 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,

4346 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4347 * doc/autoconf.texi (C++ Compiler): Document it.
4348 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4351 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4353 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4354 that caused config.status to generate 100-command sed scripts; the
4355 portable limit is 99.
4357 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4359 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4360 variable `ac_d' instead of `d' to avoid infringing namespace.
4361 Report by Ralf Menzel.
4363 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4365 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4366 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4367 * tests/tools.at (autoconf: subdirectories): New test, taken from
4368 the corresponding problem report by Ralf Wildenhues in:
4369 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4371 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4372 Quote some uses of shell variables if they might suffer unexpected
4373 globbing. This doesn't fix all instances of quoting problems that
4374 I found, just the easy ones that look safe.
4375 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4376 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4377 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4378 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4379 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

4386 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4388 * bin/autoreconf.in ($help): Reword according to the manual.
4389 Suggested by Olly Betts.
4391 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4392 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4394 * bin/autoreconf.in: Pass the directory argument to
4395 `require_configure_ac'. Fix comment.
4396 * tests/torture.at (Configuring subdirectories): Expose this.
4397 Reported by Olly Betts.
4399 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4401 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4402 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4403 Automake as follows:
4405 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4406 `$configure_in' instead of `configure.in', to preserve
4407 directory component.
4409 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4411 * config/config.guess, config/config.sub, config/texinfo.tex,
4412 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4414 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4416 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4417 test for C99 conformance; (bool) 0.5 is an integer constant
4418 expression, but (bool) -0.5 is not. Problem reported by Fedor
4419 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4421 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4423 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4424 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4425 Warn about obsolete install-sh files. Remove stray sentence
4426 fragment and fix cross reference.
4427 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4428 install -d; this undoes the 2006-05-10 change.
4429 (MKDIR_P): Mark with AN_MAKEVAR.
4430 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4431 that we don't require $INSTALL to be thread-safe. Move comments
4432 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4433 of AC_PROG_INSTALL. Output a message saying that we're checking
4434 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4435 MKDIR_P instead of AC_SUBST.
4436 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4437 Special magic for MKDIR_P, too.
4438 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4440 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4442 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4444 Sync from Automake, as follows:
4446 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4447 * config/install-sh: Initialize IFS, so field splitting isn't
4449 * config/mkinstalldirs: Likewise.
4450 * config/missing: Remove superfluous quotes. Replace all uses of
4451 `[' by `test', for consistency, and for..
4452 * config/missing (sed_minuso, sed_output): New variables.
4453 (autom4te, help2man, makeinfo): Use them. Unifies detection of
4454 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
4455 Fixes `missing' to detect `--output' for help2man. Fixes
4456 PR automake/483. Report by Dennis J. Linse.
4457 (autom4te): Document in `missing --help'.
4459 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4461 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4462 * config/install-sh: Don't use 'path' to talk about file names,
4463 as per GNU coding standards. Close a race condition reported by Ralf
4464 Wildenhues and Stepan Kasal. There is still a race condition
4465 on hosts that predate Posix 1003.1-1992, but we can't help this.
4466 Don't mishandle weird characters like space on pre-Posix hosts.
4467 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4468 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4469 AC_PROG_MKDIR_P from AS_MKDIR_P.
4470 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4471 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4472 earlier editions are not (including Automake 1.8.3).
4473 Do not suggest mkinstalldirs for thread-safety.
4474 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4475 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4476 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4477 presence of special characters and race conditions.
4478 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4479 in Autoconf's name space.
4481 2006-05-10 Bruno Haible <bruno@clisp.org>
4482 and Paul Eggert <eggert@cs.ucla.edu>
4484 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4485 from Automake with minor changes.
4486 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4488 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4490 * config/install-sh: Update to Automake CVS version, as follows:
4491 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4492 * lib/install-sh: Simplify the expr implementation of dirname.
4493 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4494 * lib/install-sh: Handle --, and diagnose unknown options.
4496 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4498 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4499 `./autom4te' to create `./testsuite', since the `all' target
4500 will ensure its presence, but `installcheck' should not create
4501 the uninstalled wrappers.
4503 * tests/torture.at (Unusual Automake input files): Skip if we
4504 detect automake < 1.8.
4506 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4508 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4509 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4510 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4513 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4515 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4516 munge (multiple) white space and other oddities.
4517 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4518 single quotes in variable assignment.
4519 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4520 and similar failures by adding multiple spaces, tabs, and other
4522 Report and different test suggested by Francesco Romani
4523 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4525 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4526 single quotes, we only need to search for single quotes; this
4527 both simplifies the search pattern, and makes us less
4528 susceptible to `echo' variations for arguments not containing
4530 (_AC_ARG_VAR_VALIDATE): Likewise.
4532 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4534 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4535 `$*' and IFS concatenation issue with traditional shells and
4536 bash-2.04. Report by Seanster@Seanster.com.
4538 2006-05-03 Bruno Haible <bruno@clisp.org>
4540 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4541 precisely which Mac OS X versions have the od problem.
4543 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4545 * doc/autoconf.texi: Use @option systematically.
4547 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4548 and Bruno Haible <bruno@clisp.org>
4550 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4552 (Integer Overflow): Mention the special case of integer division
4555 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4557 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4558 traditional shells like the Solaris one that do not use the
4559 first IFS character for assembling `$*'.
4560 Prompted by a related report from autoconf_bug@nro.ca.
4562 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4563 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4565 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4566 Mention more problems with the -e option.
4568 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4571 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4573 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4574 in URLs to improve DVI formatted output (requires texinfo 4.6).
4575 (System Services, Systemology, Shellology): Likewise.
4576 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4579 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4581 (Runtime): Fix macro argument names to match description:
4582 `action-if-found' -> `action-if-true' and similarly.
4583 (Obsolete Macros): Likewise.
4584 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4585 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4586 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4588 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4590 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4593 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

4598 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
4599 /bin/sh set unsorted output.

4620 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4621 since as_me isn't set yet.
4623 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4625 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4626 a few minor bugs in this area.
4628 * doc/autoconf.texi (Programming in M4sh): Comment out the
4629 documentation of AS_BASENAME, for now.
4630 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4631 (Limitations of Builtins) <basename>: Do not refer to
4633 * bin/autoconf.as (me): Don't use AS_BASENAME.
4634 (dir): Remove the unused variable.
4635 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
4636 AS_DETECT_REQUIRED. All uses changed.

4649 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4651 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4652 of "run time" and "run-time" changed to "runtime", for consistency.

4655 * lib/autoconf/general.m4: Likewise.
4656 * lib/autoconf/headers.m4: Likewise.
4658 * doc/autoconf.texi (Run Time): Document the exit status situation
4659 with more accuracy and detail.
4661 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4663 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4664 Archive is not officially `GNU' any more. Update URL.
4665 (Defining Directories): Likewise
4666 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4668 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4670 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4671 newline from the `trap' code to finish `config.log'; the NetBSD
4672 /bin/sh resets the exit status after an empty command, as
4673 documented in doc/autoconf.texi.
4674 Reported by Dalibor Topic <robilad@kaffe.org>.
4676 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4678 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4679 Suggested by Bruno Haible.
4681 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4683 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4684 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4685 Instead, just list the shells that we know work.
4686 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4687 changed. Be more cautious about the _cv_ variable.
4688 * tests/tools.at (Syntax of the shell scripts): Check the
4689 _cv_ variable once, at first, to avoid an internal autoconf error
4690 when sh -n does not work.
4692 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4694 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4696 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4698 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4699 use ">&-" since we're only 99.999% sure that this is portable,
4700 and since the MinGW bug is fixed in a different way.
4701 * lib/autotest/general.m4 (AT_INIT): Likewise.
4703 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4705 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4706 before opening config.log, to avoid hitting a bug on MinGW.
4708 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4710 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4711 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4712 This works around a MinGW bug reported by Eric Paire.
4713 Make sure that all writes to the log file append to it,
4714 rather than possibly losing data.
4715 * lib/autotest/general.m4 (AT_INIT): Likewise.
4717 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4719 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4722 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4726 * configure.ac (AC_INIT): Bump to 2.59d.
4728 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4732 * Makefile.maint (news-date-check): Do not require a leading `*'
4733 before the release date in NEWS.
4735 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4736 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4738 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4739 the instantiated file do not contain the string 'datarootdir'
4740 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4741 @mandir@, replace the reference '${datarootdir}' by the value.
4742 * tests/torture.at (datarootdir workaround): New test.
4743 * NEWS: Advertise this temporary fixup.
4744 Based on a patch by Bruno Haible, reported and analyzed by
4745 Paul Eggert and Noah Misch.
4747 2006-04-12 Eric Blake <ebb9@byu.net>
4749 * tests/autotest.at (Debugging a failed test): Fix comment.
4751 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4753 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4754 all the changes since 2006-04-07.
4756 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4758 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4759 succeeded, but `ln -s file dir' failed, take care to remove the
4760 leftover target before the next test, to prevent its spurious
4761 failure; also make sure `ln file dir' works before selecting it.
4762 Thanks to Keith Marshall for pointing this out.
4765 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4766 assignments in `at_debug_args', so that we put them correctly
4767 in the `run' script.
4768 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4769 Reported by Eric Blake.
4771 2006-04-11 Eric Blake <ebb9@byu.net>
4773 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4774 top-level tests after micro-suite has been run. Used in...
4775 (Debugging a successful test, Debugging script and environment),
4776 (Debugging a failed test): ...these new tests. The first of these
4778 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4779 macro, split out from...
4780 (AT_INIT): ...here, so that using -d also generates a run script.
4781 Document that -d inhibits top-level logging.
4782 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4783 inhibits top-level logging; debug scripts are created.
4785 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4787 * tests/autotest.at (Empty test, Empty check): New test to check it.
4789 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4792 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4794 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4795 the files if a problem appears. Make the empty *.at files
4796 read-only, too. Proposed by Ralf Wildenhues.
4798 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4800 * config/Makefile.am: Add comment to force updated Makefile.in.
4802 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4803 space only patch to this file, this patch causes the Makefile.in
4804 files that include freeze.mk to be updated, and thus have a
4805 newer time stamp again, which in turn makes a pristine CVS
4806 checkout have correct time stamps.
4808 * Makefile.maint (cvs-sv): New macro, to be used..
4809 (config.guess-url_prefix, config.sub-url_prefix)
4810 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4811 point to CVS text checkout of Gnulib files.
4812 (copyright-check): Bump current year.
4813 (announcement): Do not hard-wire `./announce-gen'.
4814 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4816 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4818 (wget_files): Update config.guess, config.sub, texinfo.tex by
4819 `wget-update', now that their URLs work again.
4821 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4823 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4824 Problem noted by Paul D. Smith.
4826 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4828 * doc/autoconf.texi: Remove unused words from word list.
4829 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4830 .x-sc_trailing_space: New files.
4832 * doc/standards.texi: Sync from gnulib.
4834 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4835 `LIBOBJDIR' as experimental.
4837 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4838 with a target directory; it's internally implemented as `cp'
4839 anyway, but since Autoconf advertises the possibility to use
4840 a target directory when LN_S is `ln -s', we need to find out.
4841 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4842 analyzed by Keith Marshall <keith.marshall@total.com>.
4846 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4848 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4849 confdefs.h as-is. In general, if it has backslash-newline or the
4850 like, then it doesn't work either to sort or to remove empty
4853 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4855 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4857 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4859 * lib/autom4te.in (Automake-preselections): Preselect
4862 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4864 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4865 apostrophe within a single-quoted string, as this is the usual
4866 tradition and is easier to read than '"'"'. Don't rely on the
4867 shell treating "$/" like '$/'. Use a more-consistent indenting
4870 2006-04-09 Eric Blake <ebb9@byu.net>
4872 * tests/autotest.at (Backquote command substitution),
4873 (Multiline backquote command substitution): Remove mistaken
4874 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4876 (Parenthetical command substitution, Multiline parenthetical
4877 command substitution): here.
4879 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

4912 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
4913 (C Compiler): Move AC_C_LONG_DOUBLE to ...
4914 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

4943 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
4944 of the warning introduced by the 2001-08-28 change.

4954 2006-04-07 Stepan Kasal <kasal@ucw.cz>
4956 Revert the patch from 2006-04-01 and only improve
4957 _AS_DETECT_BETTER_SHELL:
4959 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
4960 skip nonexistent directories.
4961 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
4962 only shell candidates which exist.
4963 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
4964 * lib/autotest/general.m4 (AT_INIT): No need to give three
4965 parameters to _AS_PATH_WALK.
4967 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
4968 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4970 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
4971 distinguish m4sugar macros.
4972 * tests/tools.at (autoupdating with aclocal and m4_include):
4973 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
4974 test case by Noah Misch <noah@cs.caltech.edu>.
4976 2006-04-07 Stepan Kasal <kasal@ucw.cz>

4987 * doc/autoconf.texi (Programming in M4sh): Document that
4988 AS_MKDIR_P exits the script on failure.
4989 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4991 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4993 * config/elisp-comp, config/install-sh, config/mdate-sh,

5010 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5012 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5013 whether `set' quotes correctly: redirect stderr of the tested
5014 `set', and use a subshell, for Ultrix; use `sed' instead of
5015 `grep' for zsh `set' which may write binary output; match only
5016 at the beginning of a line, to avoid false positives.
5017 In order to avoid false positives by unrelated variables with
5018 multiline content, put the dump algorithm in a subshell and
5019 unset all variables containing newlines (except some which are
5020 special to the shell). Warn about cache variables that are
5023 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5066 ac_config_<foo>s again, sometimes normalized, sometimes not.
5067 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
5068 (AC_CONFIG_COMMANDS): Do not do so here.
5069 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
5070 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
5071 2005-07-25 rewrite. Noticed by Noah Misch.
5073 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
5074 _AC_PRESERVE_HELP_ORDER, ...
5075 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
5077 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

5080 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
5081 for --help from Cygnus `configure.'
5083 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5097 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
5098 * doc/autoconf.texi (Help Formatting): New node.
5099 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
5101 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5103 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,

5125 normalizing it, consistent it with previous releases.
5126 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
5128 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
5130 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
5131 Use simplified args that Eric Blake originally suggested.
5133 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
5135 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5136 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
5137 Use 'comm' rather than N instances of grep; this also fixes a bug
5138 whereby substrings were incorrectly matched, causing us to not
5139 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
5140 (exclude_list): Exclude empty macros.
5141 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
5143 Use awk rather than grep -E or egrep, to avoid

5191 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
5192 to log, point to testsuite output tree.
5194 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

5222 Clean up _AC_COMPILER_EXEEXT* macros.
5224 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5225 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5226 ac_file to the name of the default output file and call
5227 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5228 initial `rm' of the candidate files...
5229 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use

6013 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6014 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6015 by the function rather than ignoring it.
6016 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6017 comparing its address. Intel's interprocedural optimization was
6018 outsmarting the old heuristic. Problem reported by

6036 Stepan Kasal <kasal@ucw.cz>
6038 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
6039 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
6040 make its content writable before removing it. Remove an errorneous

6067 suggested by Ben Elliston. Handle weird characters correctly.
6069 2005-09-06 Stepan Kasal <kasal@ucw.cz>
6071 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
6072 calls, so that the final expansion of this macro is shorter.
6073 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
6074 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
6075 the cleanup there. Use AS_VAR_* macros, to be more general.
6076 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
6078 * lib/autoconf/general.m4: Use AS_IF where appropriate.
6080 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

6102 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6103 "if $undefined_var;" succeeds with my shell.
6105 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6106 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6107 but change the m4_divert_text to m4_divert_once.

6126 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6127 Update limitations about when to call AC_CONFIG_HEADERS.
6128 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6129 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6130 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6131 ``Configuration Actions''; fix their index entries.
6133 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6134 options correctly. Process N-M as M-N if M is smaller than N.
6135 Process ranges correctly so that N-N will run only N.
6136 Sort and uniquify the tests that will be run. If there is more
6137 than one test, reinsert the banners for the tests.

6143 before passing the macro name to AH_TEMPLATE.
6145 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6146 now opens log after option processing; in particular, --version
6147 and --help do not touch config.log.

6164 Prepend to LIBS, not append, in examples.
6166 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6168 When building in place, set srcdir="."; suggested by Tim Van Holder.
6170 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6171 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6172 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6173 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

6192 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6193 was pushdef'ed twice while popped only once. Push it only once.

6199 prefixed by mere "===", not "configure: === ".
6201 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
6203 * Makefile.maint: Update from Bison.
6205 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6206 "<tab>" in comment, so that the point is understandable.
6208 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6210 Rewrite substantial part of lib/autoconf/status.m4.
6211 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6212 and CONFIG_COMMANDS are not processed in four separate loops.
6213 Instead, there is one main loop. This alows that the common code
6214 is expanded only once, thus config.status (and configure) is smaller.
6216 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6217 the AC_LIST_FILES and cousins macros are no longer used.
6219 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6220 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6221 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6222 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6223 contain the initialization, nor the for loop, nor the associated
6224 commands; all these go to ...
6225 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6226 _AC_OUTPUT_CONFIG_STATUS.
6227 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6228 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6229 (_AC_OUTPUT_FILE): The creation of the sed script ...
6230 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6231 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6232 _AC_OUTPUT_MAIN_LOOP.
6233 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6234 _AC_CONFIG_COMMANDS): Use ...
6235 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6236 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6237 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6238 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6239 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6240 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6242 (_AC_CONFIG_UNIQUE): Update.
6243 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6244 Replaced by this ...
6245 (_AC_LIST_TAGS): ... new common macro.
6246 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6247 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6248 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6249 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6250 this didn't belong to the `config commands' section.
6251 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6252 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6253 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6254 to the `config commands' section either.
6255 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6256 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6258 ... and many changes to the comments nearby.
6260 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6261 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6262 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6263 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6264 (#define header templates): The comment at the top of the generated
6265 header now includes the name(s) of the source file(s).
6267 Several unrelated small changes:
6269 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6270 parameter to AC_DIAGNOSE.
6271 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6272 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
6273 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
6274 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
6276 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
6277 in AC_OUTPUT doesn't double-quote it either.
6278 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the

6299 ac_cv_build_alias to ac_build_alias.
6300 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
6302 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
6303 change eliminates it. Problem reported by Alexandre Duret-Lutz.
6304 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
6305 (AC_ARG_VAR): ... here.
6306 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
6309 Keep a list of all precious variables and process them with one simple
6310 for loop, instead of expanding all commands, or, OTOH, complicated
6311 processing of output of "set".
6312 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
6313 variable names in new macro...
6314 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
6315 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
6316 a loop to assign all ac_env_* and ac_cv_env_* variables.
6317 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
6319 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
6320 its value to shell variable ac_precious_vars and call
6321 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
6322 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
6323 _AC_ARG_VAR_VALIDATE.

6356 at_top_builddir, for compatibility with older autotest.
6357 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
6358 is not set, use at_top_builddir, for compatibility with older
6359 versions of autoconf.
6361 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
6363 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
6364 Problem reported by Patrick Welche.
6366 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
6368 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
6369 sed substitution command, so that we allow | in program prefixes
6370 and program suffixes. (& is a problem anyway; we're not fixing
6372 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
6373 configure_input, top_builddir, srcdir, etc.
6374 * lib/autotest/general.m4 (AT_INIT): Likewise, for
6375 PATH_SEPARATOR in AUTOTEST_PATH.
6377 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

6385 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
6386 directories with weird names. Apparently some people like living

6410 Likewise for --header; moreover, recognize --he and --h as shortcuts
6411 for --help in that case.
6413 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
6414 matches the order of execution. No code changed.

6436 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
6437 (AC_SUBST): Call it.
6438 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
6439 the directory specific variables; but don't call it for configure_input.
6441 2005-06-28 Derek Price <derek@ximbiot.com>
6443 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
6446 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
6448 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
6449 directory have inherent problems with special characters like spaces,
6450 due to limitations in Make syntax. Problem reported by Alexandre
6452 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

6465 from Justace Clutter.
6466 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
6467 variable into diagnostic. Make the diagnostic an error, not a warning,
6468 because we really don't support spaces and suchlike in dir names.
6469 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6470 Don't worry about backslashes in srcdir; it can't happen now.
6471 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
6472 Simplify ac_optarg handling.

6497 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
6498 b, t, r, w commands require single space, while : cannot have any.
6499 (Special Shell Variables): Fix sed code this in the example.
6500 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
6501 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

6514 * doc/autoconf.texi:
6515 Don't mention Solaris versions so much, if a
6516 problem is common to all extant versions of Solaris. Say "SunOS
6517 4" instead of "SunOS" for SunOS 4.
6518 (awk): Mention more of the limitations of traditional Awk.
6519 (cat): Don't talk about cat -v.

6559 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
6561 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
6562 -u, since it outputs chatter if the input files are the same.
6563 Problem reported by Ralf Menzel.
6565 2005-06-08 Derek Price <derek@ximbiot.com>
6567 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6568 renaming them since they are about to be redefined anyhow.
6570 2005-06-08 Derek Price <derek@ximbiot.com>
6572 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
6573 redefined M4 macros to this node. Document m4_include & m4_sinclude.
6574 Move m4_undefine to alphabetical order.

6579 * doc/autoconf.texi (Introduction): Likewise.
6580 Reword to avoid some formatting glitches.
6581 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
6582 Clarify explanation of HP compiler bug.
6583 Redo example output tp match current CVS snapshot.
6584 Use @example.org in email addresses when the examples
6585 might get inadvertently cut-and-pasted into user code.
6586 Remove example of autom4te usage that doesn't seem to work now.
6587 Use modern AC_INIT (except when the example is meant to be
6588 shown with Autoconf 2.13).
6589 Update ksh info for Solaris 9 and later.
6591 Modernize description of Automake versions a bit.
6592 Don't claim a future version of Autoconf is near.

6602 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
6603 Tru64 ksh pattern matching bug. Reported against Libtool by
6604 Albert Chin <libtool@mlists.thewrittenword.com> and
6605 Nicolas Joly <njoly@pasteur.fr>.
6607 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6609 m4_cdr of one-member list was [[]] (one-member list containing an
6610 empty string) instead of [] (an empty list. Callers were skewed to
6611 match this misbehaviour. As a consequence of this:
6612 - m4_foreach([x], [], [foo]) expanded to `foo', while
6613 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6614 This bug has been fixed:
6616 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6617 expand to an empty string; print error msg if called without
6619 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
6620 misbehaviour; handle [] and [[]] correctly.
6622 2005-06-06 Stepan Kasal <kasal@ucw.cz>
6624 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

6626 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
6628 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
6630 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6631 swallow records with more than 99 fields.
6632 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6633 parse the long line.
6635 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6637 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
6638 swallow literals longer than 399. Reported by Ralf Wildenhues.
6639 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
6640 to workaround this limitation.
6642 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
6644 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
6645 to gfortran, and make these the first two compiler names
6646 checked (following the general autoconf preference for gcc).
6648 2005-06-03 Stepan Kasal <kasal@ucw.cz>
6650 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
6651 (DISTCLEANFILES): Remove $(check_SCRIPTS).
6652 (testsuite): Make sure autotest.m4f is up-to-date before using it.
6654 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
6656 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
6657 expression of unbounded size when processing the --list
6658 option. This runs afoul of a limit of 399 bytes per regular
6659 expression on AIX. Problem reported by Ralf Wildenhues.
6661 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
6663 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
6664 * doc/autoconf.texi (Particular Headers): Reword example
6665 for multiline stdbool replacement.
6666 (Setting Output Variables): Reword text a bit. Don't
6667 give all the details about |#_!!_#|.
6668 Reword description of line replacement.
6670 2005-05-31 Dan Manthey <dan_manthey@partech.com>
6672 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
6673 now contain newlines, and substituted files must be referenced on
6674 a line alone; the sed scripts to substitute them are now very
6676 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
6677 commands can be put in a sed script portably.
6678 * doc/autoconf.texi (Setting Output Variables): Document above
6679 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
6680 use of multiline substitution.
6681 * tests/torture.at: No longer expect substitution of newline to fail.
6683 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
6685 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
6686 From Ralf Menzel (trivial change).
6688 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
6690 * tests/local.at: Don't attempt to check for negated character
6691 classes in shell scripts. The test was too brittle.
6693 2005-05-25 Stepan Kasal <kasal@ucw.cz>
6695 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
6696 * doc/autoconf.texi (Limitations of Builtins): Document this
6699 2005-05-24 Stepan Kasal <kasal@ucw.cz>
6701 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
6702 common code; used in many places in the tree.
6703 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
6704 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
6706 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
6708 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
6709 messages when ac_unique_file is not found.
6710 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
6711 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
6712 commands, for consistency with AC_MSG_ERROR and such.
6714 * bin/autoconf.as: Make more use of "shift 2" in option processing.
6716 * bin/Makefile.am: Merge the two rules for creating scripts.
6718 2005-05-23 Stepan Kasal <kasal@ucw.cz>
6720 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
6721 obsolete; it was never documented.
6722 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
6724 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6726 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
6727 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
6728 (ac_top_builddir): ... this ...
6729 (ac_top_build_prefix): ... to this; the old name is also kept, for
6730 backward compatibility.
6731 (ac_top_builddir_sub): New variable, without the trailing slash,
6733 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
6734 * doc/autoconf.texi (Configuration Actions): Rename
6735 ac_top_builddir to ac_top_build_prefix.
6736 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
6737 at_top_builddir to at_top_build_prefix.
6738 * lib/autotest/general.m4 (AT_INIT): Likewise.
6740 2005-05-20 Stepan Kasal <kasal@ucw.cz>
6742 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
6745 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6747 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6748 argument to m4_foreach. I guess it was necessary in the past,
6749 but I think it's a no-op now.
6751 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6753 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6754 ``cat <<_ACEOF'' commands to one.
6755 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6756 * lib/autoconf/status.m4: On various places, use expr instead of
6758 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6759 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6760 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6762 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6763 the wrong patterns between ``case'' and ``esac.'' The previous
6764 code had false positives.
6766 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6768 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

6811 2005-05-13 Stepan Kasal <kasal@ucw.cz>
6813 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
6815 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
6816 enough arguments, similarly as in m4_bpatsubsts.
6818 2005-05-12 Stepan Kasal <kasal@ucw.cz>
6820 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
6823 2005-05-11 Stepan Kasal <kasal@ucw.cz>
6825 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
6826 for absolute directory names in one loop.
6827 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
6828 abbreviations of --version and --debug.
6830 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
6832 * doc/autoconf.texi (Autoconf Language): Be more precise about
6833 quoting rules. Problems noted by Stepan Kasal.
6834 Also, throughout this document, be more careful about white space.
6835 "blank", "white space", and "space" all have different meanings
6836 and we should be careful to say what we mean.
6838 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6840 Fix C++ related problems reported by Werner Lemberg.
6841 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
6842 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
6843 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
6844 avoid problems with C++ and throw.
6845 * tests/compile.at: .cpp, not .cc.
6847 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
6849 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6851 * doc/autoconf.texi (Generic Functions): Typos.
6853 2005-05-02 Gary V. Vaughan <gary@gnu.org>
6855 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
6856 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
6857 set by latest automake.
6859 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6861 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6862 outputs 0 on GNU/Linux these days.
6864 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6866 * doc/autoconf.texi (Autoconf Language): Add more description
6867 about quoting heuristics.
6868 (Limitations of Builtins): Describe "set -" problems.
6870 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6872 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6875 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6876 by AC_DEFINE; it was a mistake.
6877 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6879 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6881 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6883 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6885 * doc/autoconf.texi (External Software): Quadrigraphs are not
6886 processed correctly in AS_HELP_STRING; avoid this in the examples.
6887 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6888 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6889 comment and reduce m4_default([foo], []) to [foo].
6890 (m4_strip): Update the explanation.
6892 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6894 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6895 Remove core.conftest.* too; it's generated by Tru64 5.1.
6896 Problem reported by Jennis Pruett.
6897 * lib/autoconf/functions.m4
6898 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6899 Don't bother to remove core files; AC_RUN_IFELSE should do that
6902 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6904 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
6906 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
6908 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
6909 Report from Horst Wente.
6911 2005-04-15 Stepan Kasal <kasal@ucw.cz>
6913 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
6916 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
6918 * doc/autoconf.texi (External Software, Package Options): Add
6919 examples showing how to implement --with-* and --enable-* options.
6921 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6923 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6924 as well as configure.in. Problem reported by Gregorio Guidi.
6926 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6928 * doc/autoconf.texi (Particular Functions): Use gnulib's current
6929 pattern for alloca snippet.
6931 2005-04-04 Stepan Kasal <kasal@ucw.cz>
6933 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

6941 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6942 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6944 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6946 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6947 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6948 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6949 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6950 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6952 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6954 * NEWS: The configure command now warns you if you attempt to use
6955 a directory whose name contains a special character like space,
6957 * doc/autoconf.texi (Installation Directory Variables): Allow
6958 "," in file names. Do not use \@; it's not a portable regexp.
6959 * bin/Makefile.am (edit): Likewise.
6960 * lib/Makefile.am (edit): Likewise.
6961 * tests/Makefile.am (edit): Likewise.
6962 * tests/semantics.at: Likewise.
6963 * tests/torture.at: Likewise.
6964 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
6965 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6966 * doc/autoconf.texi (File System Conventions): Warn about
6967 unportable file names.
6968 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6970 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6971 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6972 ac_pwd, and quote srcdir.
6973 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6975 * doc/autoconf.texi: Fix some systematic formatting problems.
6976 ".)" needs a following @: if not at the end of a sentence, and
6977 similarly for "!)". "etc." should be preceded by a comma.
6978 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6980 2005-03-22 Bruno Haible <bruno@clisp.org>
6982 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6983 argument is often called 'build-aux'.
6985 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6987 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6988 macro AC_TRY_LINK is obsolete.
6989 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6992 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6994 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6995 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6996 from a Common Lisp's `cl'.
6997 (AC_PROG_CXX): Behave according to the documentation: don't
6998 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6999 make the variable CCC precious; use `cl.exe', not `cl'.
7001 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7002 Alexandre Duret-Lutz <adl@gnu.org>
7004 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7005 /dev/null, as "configure" shouldn't read stdin, and this insulates
7006 us from problems (e.g., when testing for "cl"). Also, do this
7007 redirection before invoking "hostname" or "uname", and keep the
7008 original input stream available via...
7009 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7010 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7011 bother with "</dev/null" since it's now done at the top of
7013 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7014 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7015 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7016 * doc/autoconf.texi (File Descriptor Macros): New section.
7017 (Printing Messages): Mention it.
7018 * tests/base.at (Input/Output): New test.
7020 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7022 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7023 newline if neither \c nor -n work, as that would output two
7024 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7026 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7028 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7029 This causes that any required macros inside will get before the if.
7030 * doc/autoconf.texi (autom4te.cache): A typo.
7032 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7034 Undo previous change, except keep the change to
7035 lib/autoconf/programs.m4 that replaced grep with shell
7036 pattern-matching. This is because net-snmp configure reads stdin.
7037 Reported by Noah Misch.
7039 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7041 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7042 from /dev/null, as "configure" shouldn't read stdin, and this
7043 insulates us from problems (e.g., when testing for "cl").
7044 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7045 before invoking "hostname" or "uname".
7046 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7047 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7048 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7049 "</dev/null" since it's now done at the top of 'configure'.
7050 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7051 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7052 Also, replace grep with shell pattern-matching, to save a process.
7054 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7056 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7057 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7058 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7061 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7063 * doc/autoconf.texi (Limitations of Usual Tools): Document that
7064 grep -q isn't portable. Improve grep -s explanation.
7065 Problem reported by Dan Manthey.
7067 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
7069 * doc/autoconf.texi (Special Shell Variables): Clarify
7070 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
7072 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
7074 * doc/autoconf.texi: Use @acronym for DJGPP.
7075 Fix some @code's that should have been @env's, and vice versa.
7076 Sort environment variable names.
7077 Mention that shells no longer inherit IFS.
7078 Don't recommend PATH_SEPARATOR=';' so strongly.
7079 Mention that $RANDOM might expand to the empty string.
7080 "symlink" and "soft link" -> "symbolic link".
7081 Improve mktemp description (reported by Bruno Haible).
7083 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
7085 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
7086 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
7088 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
7091 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
7093 * NEWS: Mention AT_COPYRIGHT.
7095 * tests/local.at (AT_CMP): Use diff directly on input files rather

7157 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

7220 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7221 Update the long comment explaining it.
7223 m4_require no longer writes an ``is required by'' line to the
7224 execution stack. It contains only one bit of non-redundant
7225 information: that the macro was required, not called. And even
7226 this bit is useless in most situations: have you ever met a macro
7227 which both calls and requires the same macro?
7229 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7230 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7238 * tests/m4sugar.at (m4_require): Expect output without the
7239 ``is required by'' messages.

7277 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7278 Warn about newline stripping in `` and $(). Update Solaris
7280 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7281 X insulates us from future changes to Posix.

7335 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7336 stored in _m4_divert_diversion or _m4_divert_dump.
7337 (m4_divert_pop): When the parameter is given, compare the symbolic
7338 name with the last diversion pushed on the stack. Previously, the
7339 current diversion was compared with the numeric value of the
7340 diversion given as the parameter.
7341 (m4_require): If the macro hasn't been expanded yet, call ...
7342 (_m4_require_call): this new macro.

7557 Don't depend on .x file explicitly, since "make" does that for us.
7558 Suggested by Stepan Kasal.

7562 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate,

7591 * doc/autoconf.texi (Libraries): Clarify problems with AC_CHECK_LIB
7592 and suggest AC_SEARCH_LIBS. Suggested by Noah Misch and Stepan Kasal.
7594 2004-12-08 Noah Misch <noah@cs.caltech.edu>
7596 * configure.ac (test suite): Cease to generate wrapper scripts.
7597 * configure: Regenerate.

7602 (MAINTAINERCLEANFILES): Delete wrapper.in.
7603 (CLEANFILES): Add wrapper.in.
7604 * tests/wrapper.as: Move AS_INIT to very top, preserving copyright in
7605 the output. Replace each $as_me with a @wrap_program@.
7606 * tests/wrapper.in: Delete it; we always build it.
7608 * bin/Makefile.am (autoconf.in): Generate it in the build directory.

7621 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
7623 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
7624 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
7625 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
7626 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
7628 2004-12-07 Stepan Kasal <kasal@ucw.cz>
7630 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

7642 out the common code to ...
7643 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
7644 value of the #define--default to 1, iff the macro was called
7645 with exactly one parameter.
7647 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
7649 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7650 "char c = '\200';" rather than "char c = 0x80;" as the
7651 latter doesn't conform to the strict C standard due to
7652 overflow on signed char hosts.
7654 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
7655 to -qlanglvl=ansi. We don't want to disable extensions.
7657 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
7659 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

7707 * doc/autoconf.texi (Autoconf Language): Explain that
7708 ``descriptions'' may not be double quotes.
7709 (Quotation Rule Of Thumb): Likewise.
7710 (Pretty Help Strings): Likewise; remove the wrong comment;
7711 simplify the examples and improve their quoting.
7713 2004-11-13 Stepan Kasal <kasal@ucw.cz>
7715 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
7716 the $1_found variable, don't test whether the file is executable;
7717 Both things are checked ...
7718 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
7719 the former ``test -f''.

7730 limitations. Reorder paragraphs for clarity.
7732 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
7734 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
7735 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
7736 variants", "Unix", and some related minor wording fixups.
7738 (Shellology, Special Shell Variables): Document that the Zsh
7739 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

7751 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
7753 * doc/autoconf.texi (auindex): New macro.
7754 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
7755 Problem reported by Stepan Kasal.
7757 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

7766 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
7768 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7769 "/usr/include", clear ac_x_includes instead of leaving it as "no"
7770 (trivial change). Problem and patch reported by Andrew Church in:
7771 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7773 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

7800 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
7801 texinfo.tex for now (done by hand now).
7802 * Makefile.maint (wget_files, cvs_files):
7803 Remove ansi2knr.c; nobody uses it.
7804 (ansi2knr.c-url_prefix): Remove.
7805 (cvs-update): Fix test for failure. I don't know why it ever
7808 * doc/autoconf.texi: Update URLs, some of which went stale.
7809 Use @uref rather than @href.
7811 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
7812 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
7814 * config/config.guess, config/config.sub, config/elisp-comp,
7815 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7816 doc/fdl.texi, doc/standards.texi: Sync with master copy.

7824 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
7825 tests/tools.at, tests/torture.at:
7826 Use "file name" rather than "filename" or "path",
7827 to be consistent with the terminology of the GNU coding standards.
7829 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7831 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7832 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7833 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7834 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7836 More fixes to support spaces in the name of the build directory.
7837 This isn't a complete fix but it's an improvement.
7839 * bin/autoconf.as (autom4te_options): New var.
7840 Use it instead of appending to AUTOM4TE, so that we can allow
7841 spaces in the build directory's absolute name.
7842 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7843 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
7844 AT_CHECK_NOESCAPE): Likewise.

7856 * doc/autoconf.texi (Function Portability): Document isinf and
7857 and isnan. From a suggestion by Kevin Ryde.
7859 * lib/Autom4te/General.pm (END): Return correct exit status even
7860 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7862 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7864 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7865 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7866 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7868 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7870 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7871 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7872 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7873 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7874 * lib/autom4te.in (Automake-preselections): Preselect
7875 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7877 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7879 * lib/autom4te.in (Automake-preselections): Preselect
7880 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7883 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7885 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7887 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7888 Document problem with "`""`" in pdksh POSIX mode.
7890 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7892 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7893 with pdksh, too. Problem reported by Patrick Welche via
7895 * doc/autoconf.texi (Shellology): Note that set -o posix is
7896 useful for pkdsh, too.
7898 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7900 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7901 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7902 Don't fail if ENV or BASH_ENV is readonly.
7903 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7904 etc. are read only. Problem reported by Ludovic Courtes.
7906 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7908 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7909 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7912 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7914 * doc/autoconf.texi (File System Conventions): Warn about
7915 names like "aux". Problem reported by Eric Blake.
7917 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7918 by zero instead of array size, so that we can use any arithmetic
7919 constant expression (instead of requiring an integer constant
7920 expression). This allows us to test expressions like DBL_MAX <
7921 LDBL_MAX, which didn't conform to the C standard using the old
7923 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7924 now that we can do floating-point tests at compile time.
7926 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7928 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7929 and LDBL_EPSILON, as the resulting expression isn't an
7930 integer constant expression and violates the C standard.
7931 Problem reported by Nelson H. F. Beebe. Also, check
7932 for "L" suffix, and check that long double doesn't have
7933 worse range or precision than double, that mixed-mode
7934 arithmetic doesn't generate a diagnostic, that double
7935 constants fit in long double.
7937 2004-06-03 Kevin Ryde <user42@zip.com.au>
7939 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7940 malloc(0) and realloc(NULL,size).
7942 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7945 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7947 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7948 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7951 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7953 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7954 can be rewritten using if-then-else. Suggested by Bruno Haible.
7956 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7958 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7959 Problem reported by Stepan Kasal.
7961 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7963 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7964 change). Patch reported by Ralf Wildenhues in
7965 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7967 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7968 function F exists if the compiler and linker let you compile an
7969 expression like (F != 0). Recent versions of GCC optimize away
7970 the reference to F in that case, since every function address must
7971 be nonzero, so the link succeeds even if F does not exist.
7972 Problem reported by Manu in
7973 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7975 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7976 "Unix". Many uses changed.
7977 (Limitations of Builtins): Explain better why the ! command isn't
7980 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7982 * lib/autom4te.in (Automake-preselections): Preselect
7983 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7985 2004-05-19 Kevin Ryde <user42@zip.com.au>
7987 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7988 referencing AC_FUNC_STRERROR_R.
7990 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7991 note pessimistic assumption when cross compiling.
7993 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7995 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7996 (until 2004) invoked subcommands with sh -e, contra POSIX.
7997 Reported by Kevin Ryde.
7999 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8001 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8002 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8003 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8004 `test -f " /usr/bin/grep"', which _always_ failed.
8005 (AC_PROG_SED): Ditto bogus PATH fix.
8006 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8007 requires that grep correctly supports _multiple_ `-e' options, rather
8008 than stating only that grep should accept `-e'.
8010 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8012 Port to C99, which requires that 'exit' be declared.
8014 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8015 to ensure that stdlib.h is included.
8016 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8017 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8018 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8019 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8020 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8021 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8022 when using 'exit' in a test; C99 requires that 'exit' be declared.
8024 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8026 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8027 now prefers 'grep' implementations that accept -e.
8028 (Limitations of Usual Tools): Describe problems of traditional
8029 egrep and fgrep with long input lines, and of traditional grep
8031 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8032 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8033 All callers changed. Append /usr/xpg4/bin to the PATH, for
8035 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8036 the user with complaints about multiple -e options.
8037 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8038 Define it with AC_PROG_GREP.
8039 * configure.ac (AC_PROG_GREP): Add.
8040 * lib/freeze.mk (GREP): New macro.
8042 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8044 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8045 a possible candidate only after all others fail, rather than
8046 consulting it first. This improves backward compatibility by
8047 better reflecting the way shell selection occurred in previous
8048 versions of Autoconf, and should help to avoid triggering latent
8049 problems in other packages, such as the one in Automake where zsh
8050 is not handled robustly:
8051 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8052 Although it is not Autoconf's responsibility to work around
8053 problems in Automake, it nevertheless makes sense to avoid
8054 introducing unnecessary incompatibilites.
8056 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8057 Gary V. Vaughan <gary@gnu.org>
8059 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess

8063 nested we are in this macro. Break out of all 3 nested loops if
8064 ac_path_TOOL_found is set.
8066 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8068 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
8069 of the _AS_PATH_WALK loop too if GNU flavor is found.
8071 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
8073 * doc/autoconf.texi (Limitations of Make): Update documentation
8074 for `$<'. New entry `Long lines', based on a report from Simon
8075 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
8076 paragraph about DJGPP, based on a mail from Richard Dawe.
8078 2004-04-20 Paul Eggert <eggert@twinsun.com>
8080 * tests/c.at (C keywords): Don't assume that GCC supports
8081 "restrict" and "inline", as sufficiently-old GCC versions do not
8082 (also, GCC configured to be in pedantic C89 mode does not).
8083 Problem reported by Sumit Pandya in:
8084 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
8086 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
8087 consider -g to work if it generates warnings when plain compiles
8088 don't. Problem reported by Braden McDaniel in:
8089 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
8091 * doc/autoconf.texi (Slashes): New section, to document a problem

8100 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8102 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8103 best tool so far counter rely on the tool path variable name to
8104 avoid checks for one tool being affected by the results of running
8105 the length check on a previous tool.
8107 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
8108 match expression argument, as different greps have different
8109 regular expression flavours.
8110 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
8112 (AC_PROG_EGREP): Pass 'EGREP$'.

8122 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
8123 Types, Specific Compiler Characteristics, System Services,
8124 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
8125 etc. consistently instead of 'long', 'short', 'unsigned' etc.
8126 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
8127 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

8138 2004-03-28 Paul Eggert <eggert@twinsun.com>
8140 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
8141 now defines HAVE_DECL_TZNAME if it is declared, when
8142 HAVE_STRUCT_TM_TM_ZONE is not defined.
8143 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
8144 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

8153 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
8155 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
8156 Fortran compiler is ifort, also added pghpf; thanks to Nelson
8157 H. F. Beebe for the bug report.

8192 * tests/mktests.sh: Do not generate tests for the
8194 * NEWS: Document these changes.
8196 * doc/autoconf.texi: Avoid macros with unbraced arguments,
8197 they make TeX hang up.

8213 * bin/Makefile.am (edit): Don't use $< in a context where
8214 POSIX doesn't require support for it. Use $@.in instead.
8215 Problem reported by Anthony N. Frasso in
8216 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
8217 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

8221 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
8222 from the next generation of Libtool.
8223 * lib/autom4te.in (Autoreconf-preselections): Ditto.
8225 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8227 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
8228 is not always thread-safe. Report from Nathanael Nerode.
8230 2004-02-18 Paul Eggert <eggert@twinsun.com>
8232 Fix a dependencies problem, stemming from a Autoconf 2.59 build
8233 problem on QNX reported by Stephen Rasku in
8234 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
8236 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
8237 $(m4sh_m4f_dependencies); this removes a FIXME.
8238 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
8239 (MAINTAINERCLEANFILES): Split into pieces,
8240 one per related section. Add $(srcdir)/wrapper.in.
8242 2004-02-09 Paul Eggert <eggert@twinsun.com>
8244 * doc/autoconf.texi (Setting Output Variables): Emphasize that
8245 AC_SUBST provides no portable way to escape literal newlines.
8247 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8248 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8249 Darwin uses -lcrt2.o and there's little point to cataloging all
8250 the system variants. Partial fix reported by Andreas Waechter in:
8251 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

8267 the behavior of the third argument.
8268 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
8269 correctly the behavior of the third argument. Document
8270 what the three macros that AU_DEFUN defines do. Fix
8271 warning message when the third argument includes $0

8278 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

8295 use AS_INIT_WITH_SHELL_FN.
8296 * bin/autoconf.in, tests/wrapper.in: Regenerated.

8324 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
8326 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8327 2003 (except 1997) to the list of copyright years. This undoes
8328 the 2003-05-22 change, which removed the older years from the list.
8329 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

8335 grep or ggrep program in PATH that accepts as long lines as
8337 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
8339 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
8340 egrep and fgrep respectively if $GREP -E/-F don't work.
8341 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
8342 _AC_PROG_GREP, and AC_PROG_SED.
8343 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
8344 longest input length accepted by a command.

8373 2004-01-26 Paul Eggert <eggert@twinsun.com>
8375 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8376 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8377 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8378 not <inttypes.h>. Problem reported by Tim Mooney in
8379 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
8380 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8383 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8384 otherwise "make check" fails because it forbids cmp (I guess
8385 because cmp treats files as binary on DOS-like systems).
8387 * tests/mktests.sh: Update copyright date to 2004, since some tests
8388 have changed in 2004.
8390 2004-01-23 Gary V. Vaughan <gary@gnu.org>
8392 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
8393 non-truncating sed or gsed program in PATH.
8394 * tests/acprograms.at: Add it.
8395 * doc/autoconf.texi (Particular Programs): Document it.
8398 2004-01-15 Paul Eggert <eggert@twinsun.com>
8400 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8401 -std1 disables some useful extensions on Tru64. Problem reported
8403 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
8405 2004-01-14 Paul Eggert <eggert@twinsun.com>
8407 * doc/autoconf.texi (Programming in M4sh): Document that
8408 AS_MKDIR_P succeeds if the destination is a symbolic link
8409 to an existing directory.
8410 (Limitations of Usual Tools): Note that mkdir -p might not
8411 succeed on symlinks to directories.
8413 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
8415 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
8416 * bin/autoheader.in: Grammar fix in message.
8417 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

8425 2004-01-10 Jim Meyering <jim@meyering.net>
8427 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
8429 2004-01-09 Paul Eggert <eggert@twinsun.com>
8431 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
8432 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
8433 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
8434 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
8435 AC_COMPILE_IFELSE, since we now assume our caller invokes
8436 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
8437 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
8438 of AC_RUN_IFELSE; this avoids the warning mentioned above.
8439 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
8441 2004-01-07 Paul Eggert <eggert@twinsun.com>
8443 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
8444 `"'...'"`, as it's confusing (and I suspect it may not work on
8445 some platforms). The code was incorrect anyway, as it assumed
8446 that \$ evaluated to itself in that context. Reported by
8447 Alexandre Duret-Lutz.
8449 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

8457 example, and add more examples. Reported by Eric Sunshine.
8459 2004-01-05 Paul Eggert <eggert@twinsun.com>
8461 * doc/autoconf.texi (Limitations of Usual Tools):
8462 Remove warning against "rm -fr" introduced yesterday; it
8465 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
8466 autoscan, autoupdate, ifnames): Don't use chmod -w.

8805 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8807 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
8808 -mGLOB_options_string stuff for Intel ifc, which can cause
8809 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

8832 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8833 cache variable instead of $G77 to decide whether to include -O2,
8834 since $G77 is specific to Fortran 77.
8836 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8838 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
8839 free" flag. Re-order flags tested into rough order of popularity.

8843 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the

8914 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8915 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

8920 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8921 directory for AC_CONFIG_COMMANDS' first argument exists.
8922 This makes valid the invocation of _AC_SRCPATH that follows.
8923 Reported by Eric Sunshine.
8924 * doc/autoconf.texi (Configuration Commands): Adjust.
8926 2003-09-26 Akim Demaille <akim@epita.fr>

8947 The test suite are sometimes assigning timings incorrectly.
8948 Reported by Henk Krus.
8949 Diagnosed by Nicolas Joly.
8951 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8953 Instead of making AT_help a sequence of assignments to grow

8957 (at_times_skip): Flip the meaning and rename as...

8968 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8969 (ifnames): chmod -w.
8970 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8971 executables, not bin/ executables! Otherwise all the magic needed
8972 to find non installed files is turned off. This caused a failure
8973 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8974 as found in its environment (sent by tests/autoreconf): pointing
8975 to bin/autom4te that could not find its files.
8976 * tests/mktests.sh: Force the replacement of generated files, for
8977 the sake of "mv" program that are interactive when overwriting a

9074 Add support for newer Fortran dialects. The F77 interface is
9075 unchanged, and continues to support Fortran 77. New FC macros
9076 correspond to all the old F77 macros, with output variables FC,
9077 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest

9206 2003-08-21 Akim Demaille <akim@epita.fr>
9208 First stab at preserving warnings between calls to autom4te,
9209 including when the cache is used.
9211 There are still several issues: (i) there are too many runs of m4
9212 (one for include, one for warnings, and some more), (ii) warnings
9213 spreading on several lines are not handled gracefully, (iii) the
9214 code meant to have the call stack display for errors does not work
9215 (its handling should move from m4 to autom4te).
9217 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9219 (@preselect): Add m4_warn.
9220 ($exit_status): Remove, use $exit_code.
9221 ($help): Use Autom4te::ChannelDefs::usage.
9222 (&handle_m4): No longer define the m4_warnings.
9223 At each run, extract and report the warnings.
9224 Always cache the result, including if the exit status is on
9225 failure, since if nothing changes, we should result in the same
9226 failure, hence we can use the cache.
9227 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9228 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9230 (m4_warn): Redefine as a do-nothing: it is its invocation that
9231 matters, as warnings are now reported via traces.
9232 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9233 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9234 the latter reveals calls to the former.
9238 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
9240 2003-08-21 Akim Demaille <akim@epita.fr>
9242 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

9250 (&parse_warnings): Accept a list of warning requests.
9251 (&usage): Return a string, not a side effect.
9252 (cross): New warning category.

9257 (&require_configure_ac): Accept an optional directory argument.
9258 ($configure_ac): Remove.

9261 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
9262 * bin/autoscan.in: Adjust.
9264 2003-08-20 Akim Demaille <akim@epita.fr>
9266 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
9267 Reported by Alexandre Duret-Lutz.
9269 2003-08-20 Akim Demaille <akim@epita.fr>
9271 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9272 * bin/autom4te: Adjust.
9273 In particular, be Autoconf tools are really silent when properly
9274 working, bind the verbosity of the 'note' channel to $verbose.
9275 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
9276 (&xsystem, &contents): Remove, since they are exported by...
9277 * lib/Autom4te/FileUtils.pm: this.

9280 * lib/Autom4te/FileUtils.pm: here.

9400 not all of them. This fixes 1. the fact that when testing
9401 Autoconf there are many many config.log, 2. the incorrect use of
9402 top_srcdir to find config.log.
9403 Don't mix the detailed output of failed test with the summary of
9404 failures. Rather, append detailed log afterwards.

9491 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
9493 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
9494 Do not call `_exit()', simply modify `$?'.
9495 (xsystem): Reset $! before running system, and check it afterward.
9496 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
9497 63 for version mismatches.
9499 2003-05-23 Akim Demaille <akim@epita.fr>
9501 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
9502 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
9503 the middle of a line).
9504 * lib/m4sugar/m4sugar.m4: Likewise.
9505 Remove useless spaces in comments.
9507 2003-05-23 Akim Demaille <akim@epita.fr>
9509 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
9510 exit 63, so that we (or Automake's "missing") can tell the
9511 difference with a plain failure.
9512 * doc/autoconf.texi (Notices): Adjust.
9514 2003-05-23 Akim Demaille <akim@epita.fr>
9516 * Makefile.am, bin/Makefile.am, config/Makefile.am,
9517 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
9518 White spaces cleanup.
9520 2003-05-22 Jim Meyering <jim@meyering.net>
9521 Paul Eggert <eggert@twinsun.com>
9523 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9524 Remove `#include <stdlib.h>' from the list; we should never
9525 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9526 resulting namespace pollution would cause other tests to fail.
9527 Configure scripts run with some older versions of g++ and HP's
9528 aCC would fail due to such an #include. Problems reported by
9529 Matthew Mueller in <http://bugs.debian.org/120704> and by
9531 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9532 In the test, use the test declaration before including <stdlib.h>,
9533 as that's closer to how it'll be used.
9535 2003-05-23 Akim Demaille <akim@epita.fr>
9537 * doc/autoconf.texi (Header Portability): ucred.h.
9540 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
9542 Overhaul Autotest's logging: generate separate log files
9543 in testsuite.dir/NNN/testsuite.log, and append them to
9544 testsuite.log instead of re-running the test verbosely.
9546 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9547 file descriptor, write 0 to at_status_file instead of setting
9548 at_status=0, initialize some new variables (at_status_file,
9549 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9550 to rerun the tests, instead append the at_group_log to the
9551 at_suite_log when a test fails.
9552 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9553 with the AS_MESSAGE_LOG_FD redirected to stdout.
9554 (AT_CLEANUP): save the output status in $at_status_file
9555 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9557 (AT_CHECK): since tests are run with a redirected stdout,
9558 and used to be re-run in verbose mode, turn some $at_verbose
9559 into echo, and don't redirect the output of testing stdout
9562 * lib/autotest/autoconf.texi (testsuite Scripts): Update
9563 the name of the debugging directory and information about
9566 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

9676 From Matthias Andree.
9678 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
9680 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
9683 2003-05-06 Akim Demaille <akim@epita.fr>
9685 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9686 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9687 by aclocal.m4 is changed it might require the importing of another
9688 m4 extension file, i.e., aclocal must be run.
9690 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9691 (&parse_args): Use --force with aclocal if required and supported.
9692 (&autoreconf_current_directory): Use &run_aclocal.
9694 2003-05-06 Akim Demaille <akim@epita.fr>
9696 Lock autom4te's cache.
9698 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
9699 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
9700 argument instead of a file name, so that the request file remains
9701 open during the whole autom4te run.
9702 ($icache_file): New.
9703 (&freeze): Lock the $icache_file.
9705 2003-04-29 Derek Price <derek@ximbiot.com>
9707 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
9708 seperator with m4_append_uniq(). It doesn't work.
9709 (AT_CLEANUP): Add `;' to end of at_help_all.
9710 (AT_INIT): Allow --keywords to be specified more than once. When
9711 grepping $at_help_all for keywords, use the field and keyword
9712 seperators to ensure a complete keyword match. Alter at_prev handling
9713 to support the new --keywords behavior.
9715 2003-04-27 Karl Berry <karl@freefriends.org>
9717 * doc/autoconf.texi: Make the dir entries in the autoconf manual
9718 align better with others. I also made some of the individual
9719 entries on one line, for brevity and to make it easier for me to
9720 sort my dir-example file in the Texinfo distribution :).
9722 2003-04-12 Jim Meyering <jim@meyering.net>

9781 Suggested by Paul Eggert.
9783 2003-03-28 Akim Demaille <akim@epita.fr>
9785 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

9787 header causes problems.
9789 2003-03-28 Akim Demaille <akim@epita.fr>
9791 * tests/torture.at (Configuring subdirectories): Require aclocal
9792 1.4, otherwise the test fails, as it does support configure.ac.
9793 This fixes the "test 40 failed" bug reports.
9795 2003-03-28 Akim Demaille <akim@epita.fr>
9797 * doc/autoconf.texi (C Compiler): `#line' portability.

9808 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
9809 use new diversions in preparation for accepting new arguments and
9810 allowing scripting around tests.

9863 about `$<' in inference rules, it was a bogus interpretation of
9864 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
9865 Tru64 make in the "target lookup" section.
9866 (Automake): Automake 1.5+ no longer requires special tools to be
9867 present on the developer's host.

9888 When constructing paths with IFS=:, quote the path. If we're
9889 constructing a DOS-style absolute path, we don't want to split it
9892 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
9895 2003-02-25 Pavel Roskin <proski@gnu.org>
9897 * bin/autoheader.in: Add missing newline when printing

9913 format starting with "-".
9915 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9917 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
9918 is not portable inside Makefile.
9920 2003-02-20 Akim Demaille <akim@epita.fr>
9922 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9923 compiler says yeah, but preproc says nope, compiler is right.
9924 Conversely, prompt the reader to send a bug report to the
9925 maintainers of the package, not of Autoconf.
9927 2003-02-20 Klee Dienes <kdienes@apple.com>
9929 * bin/autoreconf.in (autoreconf_current_directory): Properly

9940 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9941 innocuous variant befor including <limits.h> or <assert.h>. This
9942 works around a bug reported by Albert Chin: HP-UX 11i
9943 (and earlier versions) have a <limits.h> that declares
9944 gettimeofday and many other functions.
9946 2002-12-03 Paul Eggert <eggert@twinsun.com>
9950 * NEWS, configure.ac: Update version.
9952 * doc/fdl.texi: Upgrade to FDL version 1.2.
9954 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9955 nontrivially in main's body, so that f's external declaration is
9956 not optimized away in AIX. This should fix the bug reported by
9958 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9960 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9961 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9962 defined, to support freestanding compilers. This should fix the
9963 bug reported by Momchil Velkov in
9964 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9966 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9967 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
9968 obsolete AC_CHECK_TYPE. The missing empty arg was reported
9969 by Simon Josefsson in
9970 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.

9979 \(.*\) match is too long and there is something more to be checked.
9980 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

10000 2002-11-14 Akim Demaille <akim@epita.fr>
10002 * Makefile.maint: Sync with Bison, i.e.:
10003 (po-check): Scan .l and .y files instead of the
10004 .c and the .h files that they generate. This fixes the bug
10005 reported by Tim Van Holder in:
10006 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10007 Look for N_ as well as for _. Try to avoid matching #define for

10028 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
10029 option. Process --recheck after parsing all options. Pass -q
10030 option to configure on --recheck.
10031 (AC_OUTPUT): Pass -q from configure to config.status.

10066 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10068 We _have_ to stop using the old compatibility scheme that tried to
10069 avoid useless backslashes because Libtool 1.4.3 contains a
10070 AC_DEFINE([error_t], [int],
10071 [Define to a type to use for \`error_t' if it is not
10072 otherwise available.])
10073 We _have_ to quote the single quote and backslashes with \. The
10074 old compatibility scheme saw that ` was backslashed, and therefore
10075 did not quote the single quote. Hence before this patch, Autoconf
10076 was not compatible with Libtool.

10467 Reported by Alexandre Duret-Lutz.
10469 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

10496 * tests/tools.at (autoupdate): Adjust.
10497 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
10499 2002-10-11 Akim Demaille <akim@epita.fr>
10501 No longer use CPP to check for the existing of headers: use CC to
10502 check for compilability.
10504 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
10505 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
10506 (_AC_CHECK_HEADER_NEW): Rename as...
10507 (AC_CHECK_HEADER): this.
10509 * lib/autotest/general.m4 (AT_INIT): Include the failed test
10510 numbers in the Subject suggestion.
10512 2002-10-11 Akim Demaille <akim@epita.fr>
10514 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
10515 Suggest using AC_CHECK_DECLS instead.
10517 2002-10-11 Akim Demaille <akim@epita.fr>
10519 * tests/torture.at (AC_ARG_VAR): Have configure report the value
10522 2002-10-11 Akim Demaille <akim@epita.fr>
10524 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
10525 file name to enable parallel executions.
10526 From Sam Varshavchik.
10528 2002-10-08 Akim Demaille <akim@epita.fr>
10530 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10531 aclocal invocation, as Gettext macros might not be visible to
10533 Instead of blindly running autopoint, scan configure.ac (not the
10534 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10535 Reported by Paul D. Smith.
10537 2002-10-08 Paul Eggert <eggert@twinsun.com>
10539 Work around problems found when POSIXLY_CORRECT=1 is set.
10540 None of this seems to have anything to do with POSIX, really,
10541 but it's how Perl getopt works.
10542 * bin/autom4te.in (parse_args): Configure GetOpt with
10544 * doc/autoconf.texi (Invoking autom4te):
10545 --warning -> --warnings.
10546 * lib/autom4te.in: --warning -> --warnings.
10548 2002-09-28 Akim Demaille <akim@epita.fr>
10550 * doc/autoconf.texi (autom4te.cache): New section.
10552 2002-09-28 Akim Demaille <akim@epita.fr>
10554 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
10555 (Automake-preselections): Update.

10558 2002-09-28 Akim Demaille <akim@epita.fr>

10561 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
10562 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10563 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
10565 2002-09-28 Akim Demaille <akim@epita.fr>
10567 * tests/torture.at (Configuring subdirectories): Be robust to
10568 users who use config.site to require for a cache: in this case,
10569 the two last configure runs, using two different sets of
10570 arguments, trigger a legitimate error.
10572 2002-09-28 Akim Demaille <akim@epita.fr>
10574 * tests/m4sh.at (Functions Support, Functions and return Support):
10577 2002-09-28 Akim Demaille <akim@epita.fr>
10579 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
10580 autoheader are Perl programs.
10581 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
10582 (autom4te): Specify that the sources are in the $srcdir.

10591 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
10592 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

10605 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10606 (.m4.m4f): Don't pass --prepend-include, since that's done by
10607 tests/autom4te itself.
10608 * lib/autoscan/Makefile.am: Include freeze.mk.
10609 (autoscan.list): New target --this file is no longer a source.
10610 (autoscan.pre): New file.
10612 2002-09-28 Akim Demaille <akim@epita.fr>
10614 * bin/autoscan.in (@kinds): Make them singular.
10616 (&init_tables): When --debug, report the list of rules to ease
10617 tracking changes in autoscan.list.
10618 * lib/autoscan/autoscan.list (function): Strip comments, sort.
10620 2002-09-28 Akim Demaille <akim@epita.fr>
10622 * lib/autoscan/functions, lib/autoscan/headers,
10623 * lib/autoscan/identifiers, lib/autoscan/makevars,
10624 * lib/autoscan/programs: Merge into...

10626 * bin/autoscan.in (&init_tables): Adjust.
10628 2002-09-28 Akim Demaille <akim@epita.fr>
10630 * lib/autoscan/functions, lib/autoscan/headers,
10631 * lib/autoscan/identifiers, lib/autoscan/makevars,
10632 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10633 `functions' line is now prefixed with `function:'.
10634 * bin/autoscan.in (&init_tables): Adjust.
10636 2002-09-28 Akim Demaille <akim@epita.fr>
10638 From now on, autoscan files must always map a macro name to a
10639 word: there is no `default' macro for autoscan.
10641 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10643 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10646 2002-09-28 Akim Demaille <akim@epita.fr>
10648 * bin/autoscan.in (%c_keywords): Remove.
10649 (&used): Keep only track of the words we might be interested in.
10650 (&output_kind): It is no longer needed to look for non active
10653 2002-09-27 Akim Demaille <akim@epita.fr>
10655 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

10657 * lib/autoscan/functions: Adjust.
10658 * doc/autoconf.texi (Particular Functions): Adjust.
10660 2002-09-27 Akim Demaille <akim@epita.fr>

10664 Thanks to Bill Moseley and Paul Eggert.
10665 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
10666 the tmpdir must be created.
10667 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
10668 dir be in the build tree, instead of $TMPDIR.
10670 2002-09-27 Akim Demaille <akim@epita.fr>
10672 * bin/autoscan.in: Improve the comments.
10673 (&parse_args): Drop obsolete undocumented options.
10674 (&output_kind): Output warnings.
10675 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

10680 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
10681 Reported by Ralf Corsepius.
10682 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10684 2002-09-26 Akim Demaille <akim@epita.fr>
10686 Single suffix rules and seperated dependencies are not portable.
10688 * doc/autoconf.texi (Installation Directory Variables): Update.
10689 (Limitations of Make): Some about `Single Suffix Rules and
10690 Separated Dependencies'.
10691 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10692 (ifnames, autoscan, autom4te): Un-factor into several rules.
10694 2002-09-25 Paul Eggert <eggert@twinsun.com>
10696 * BUGS (Interoperability bugs): New section. Mention libtool
10697 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10699 2002-09-24 Paul Eggert <eggert@twinsun.com>
10701 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10702 make handles suffix-rules differently from GNU make.
10704 * bin/Makefile.am (SUFFIXES, .in): Remove.
10705 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
10706 Move the body of the old .in rule here.
10708 2002-09-16 Akim Demaille <akim@epita.fr>
10710 i960 compilers create `b.out' files by default.
10711 Reported by Ralf Corsepius.
10713 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10714 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10716 2002-09-13 Paul Eggert <eggert@twinsun.com>
10718 * doc/autoconf.texi (Particular Headers): Remove obsolete
10719 reference to `struct timezone' in the description of
10722 2002-09-13 Akim Demaille <akim@epita.fr>
10726 * config/config.sub, config/config.guess: Update.
10727 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10728 * Makefile.am: Adjust.
10730 2002-09-13 Akim Demaille <akim@epita.fr>
10732 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10733 reading config.log when the compiler is rejected.
10734 Suggested by Guido Draheim.
10736 2002-09-13 Akim Demaille <akim@epita.fr>
10738 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10739 (chdir_init) might hang when stat'ing mounted directories.
10740 Reported by Vance Shipley.
10742 2002-09-12 Akim Demaille <akim@epita.fr>
10744 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10747 2002-09-12 Akim Demaille <akim@epita.fr>
10749 * doc/autoconf.texi (Defining Symbols): Present two different
10750 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10751 difference between 1 argument calls, and 2-3 argument calls.
10753 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10755 * doc/autoconf.texi: Review grammar and punctuation.
10757 2002-09-11 Paul Eggert <eggert@twinsun.com>
10759 * doc/autoconf.texi: Fix minor formatting, spelling, and
10761 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10762 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10765 2002-09-11 Akim Demaille <akim@epita.fr>
10767 * doc/autoconf.texi (Questions): Rename as...
10769 (Defining Directories): New.
10771 2002-09-09 Akim Demaille <akim@epita.fr>
10773 * doc/autoconf.texi (Making testsuite Scripts): Update.
10774 Suggested by Nishio Futoshi.
10776 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10778 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10779 plain `@' is wanted.
10781 2002-09-09 Akim Demaille <akim@epita.fr>
10783 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10784 `duplicates', since the algorithm was too naive and could keep
10785 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10786 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10787 Reported by Ralf Corsepius.
10788 * tests/torture.at (Configuring subdirectories): Exercise these
10791 2002-09-09 Akim Demaille <akim@epita.fr>
10793 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10794 looking for a replacement file.
10795 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10796 directory is relative.
10797 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10798 directory definition.
10799 Reported by Andreas Schwab and Jim Meyering.
10801 2002-09-06 Akim Demaille <akim@epita.fr>
10803 * doc/autoconf.texi (Setting Output Variables): Clarify what
10804 precious variables are.
10805 Suggested by Pontus Skoeld.
10807 2002-09-05 Akim Demaille <akim@epita.fr>
10809 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10810 (ifnames, autoscan, autom4te): Since we don't only depend on
10811 configure.ac variables (such as VERSION etc.), but also on prefix
10812 and so forth, depend on Makefile, not configure.ac.
10813 Reported by Alexandre Duret-Lutz.
10814 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10816 2002-09-05 Kevin Ryde <user42@zip.com.au>
10818 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10819 doesn't seem to be confined to ia64, just say "some versions".
10821 2002-09-04 Akim Demaille <akim@epita.fr>
10823 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10825 * Makefile.am (maintainer-clean-local): Remove.
10826 (MAINTAINERCLEANFILES): Remove COPYING.
10828 2002-09-03 Paul Eggert <eggert@twinsun.com>
10830 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10831 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10834 2002-09-03 Akim Demaille <akim@epita.fr>
10836 * configure.ac: Bump to 2.53d.
10837 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10838 as of today, on Automake's team suggestion.
10840 2002-09-03 Akim Demaille <akim@epita.fr>
10844 2002-09-02 Akim Demaille <akim@epita.fr>
10846 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10848 * configure.ac: Disable SITE_MACRO_DIR.
10850 2002-09-02 Jim Meyering <meyering@lucent.com>
10852 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10853 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10854 Also, tweak grammar: s/make sure to/be sure to/.
10856 2002-09-02 Paul Eggert <eggert@twinsun.com>
10858 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10859 directory names are generally preferable to physical names.
10861 2002-09-02 Akim Demaille <akim@epita.fr>
10863 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10864 Reported by Raja R. Harinath.
10865 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10866 * bin/autoupdate.in: Use error instead of die.
10868 2002-09-01 Paul Eggert <eggert@twinsun.com>
10870 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10871 ordinary shell concatenation rather than echo+tr+sed command that
10872 runs afoul of a long-line-related sed bug in Solaris 8.
10874 * bin/autoheader.in (parse_args): --warning -> --warnings.
10876 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10877 stdout, as traditional "ls" does.
10878 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10879 _AC_COMPILER_EXEEXT_O): Likewise.
10880 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10882 * bin/autoconf.as: Add --prepend-include option. This patch was
10883 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10884 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10886 * bin/autoconf.in, configure: Regenerate.
10888 * doc/autoconf.texi (Special Shell Variables): Mention
10889 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10891 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10892 MAILPATH and set PS1, PS2, PS4 to default values, to work
10893 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10894 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10895 the Autoconf documentation specifies; fall back to "unset" only if
10896 this fails. Use a shell for-loop for this rather than an m4 loop,
10897 to shorten the output script.
10899 2002-08-30 Paul Eggert <eggert@twinsun.com>
10901 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10902 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10903 for the CDPATH problem. Document PWD.
10904 (Limitations of Builtins): Document the problem that "cd $foo" and
10905 "ls $foo" may refer to different directories in shells conforming
10906 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10907 example, since the old example is now out of date.
10909 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10910 FOO" and "ls FOO" talk about different directories; this catches
10911 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10914 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10915 of rolling our own unset.
10916 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10917 in practice we needn't worry about CDPATH if unset doesn't work.
10919 * Makefile.in, aclocal.m4, bin/Makefile.in,
10920 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10921 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10922 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10923 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10924 tests/Makefile.in: Regenerate with Automake 1.6.3.
10926 * config/config.guess, config/config.sub, config/mkinstalldirs:
10929 * configure: Regenerate with self.
10931 2002-08-30 Kevin Ryde <user42@zip.com.au>
10933 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10936 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10938 * bin/autom4te.in (Request::load): Correctly test for "do" read
10941 2002-08-29 Akim Demaille <akim@epita.fr>
10943 * lib/Autom4te/General.pm (&xqx): New.
10944 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10945 hand, which is not portable.
10947 * bin/autom4te.in: Use them.
10948 Use &error instead of die.
10949 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10952 2002-08-17 Paul Eggert <eggert@twinsun.com>
10954 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10955 default list of compilers to try, since it was long ago superseded
10956 by the ksh fc builtin. Suggested by Steven G. Johnson.
10958 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10960 * doc/autoconf.texi (Invoking autom4te): End the option table,
10961 fixing a bug introduced by the previous patch.
10962 (Limitations of Make): Add a 'target lookup' subentry in the
10963 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10965 2002-07-29 Mark D. Roth <roth@feep.net>
10967 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10968 options and use $AUTOM4TE_PATH.
10969 * doc/autoconf.texi: Remove documentation of autom4te
10970 --include-envvar and --site-macro-subdir options and document
10971 use of $AUTOM4TE_PATH.
10972 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10973 arguments from each language section.
10975 2002-07-29 Paul Eggert <eggert@twinsun.com>
10977 * doc/install.texi: Include copyright symbol in copyright notice.
10979 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10981 (AM_MAKEINFOFLAGS): New macro.
10982 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10983 * Makefile.am (INSTALL): Use the new macros.

11272 This improves on an earlier suggestion by H. Peter Anvin.
11274 2002-05-16 Paul Eggert <eggert@twinsun.com>
11276 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11277 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11278 Both macros now accept an optional source-dir arg.
11279 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11281 * NEWS: Document this.
11282 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11284 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11285 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11286 not for GNU extensions; this undoes part of the 2000-11-03 change,
11287 reverting to 2.13-compatible behavior.
11288 Add new optional argument DIR.
11289 (AC_FUNC_FNMATCH_GNU): New macro.

11295 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11296 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11297 and it causes a 'test' syntax error if it fails.
11298 Bug reported by Stephen Gildea.
11300 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11301 If prototypes are supported, use them to check this at compile-time,
11302 instead of trying to check it at run-time. If we must do a run-time
11303 check, assume that setvbuf is standard when cross-compiling, as
11304 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11305 Bug reported by Paul D. Smith.
11307 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11308 argument specifying location of getloadavg.c. This removes a
11309 FIXME. This idea was taken from Jim Meyering's implementation in
11311 * doc/autoconf.texi (Particular Functions): Document this.
11312 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11313 that's what the code does; this fixes a bug reported by

11319 autopoint instead of gettextize.
11320 ($uses_alocal): Rename as...
11321 ($uses_aclocal): this.
11322 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11323 Suggested by Bruno Haible.

11329 2002-04-29 Paul Eggert <eggert@twinsun.com>
11331 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11332 files to be 1 second older; just set them to be the same time.
11333 Also, sleep 1 second after the first aclocal, to work around
11334 problems with sub-second time stamps on the input files.
11336 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11338 * doc/autoconf.texi: Mention "set -e -x" lossage

11345 From Christian Cornelssen.
11347 2002-04-29 Akim Demaille <akim@epita.fr>
11349 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11350 of lack of $LINENO support, then the test will compare the $LINENO
11351 in testsuite vs. the lineno in the test file. This is wrong, of
11353 Be sure to protect it.
11354 Reported by Patrick Welche.
11356 2002-04-25 Akim Demaille <akim@epita.fr>
11358 * doc/autoconf.texi (Obsolete Macros): Typo.
11359 Reported by Vladimir Volovich.
11361 2002-04-25 Akim Demaille <akim@epita.fr>
11363 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11364 than some of the input files, hence, on the second run of aclocal,
11365 if some of its input are younger, make them older.
11366 Suggested by Paul Eggert.
11368 2002-04-25 Akim Demaille <akim@epita.fr>
11370 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

11377 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11379 (_AC_INIT_PREPARE): Use them to log them.
11380 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11381 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11382 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11383 _AC_SUBST_FILES and _AC_SUBST_VARS.
11384 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11386 2002-04-24 Akim Demaille <akim@epita.fr>
11388 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11389 autoheader, so that automake does not complain about a missing
11390 config.h.in that was to be created.
11392 2002-04-23 Akim Demaille <akim@epita.fr>

11474 that is not portable to Zsh.
11476 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
11478 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
11479 from aclocal.m4 too.
11481 2002-04-12 Akim Demaille <akim@epita.fr>
11483 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
11485 2002-04-10 Akim Demaille <akim@epita.fr>
11487 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
11488 workaround for ${1+"$@"}.
11489 * doc/autoconf.texi (Shell Substitutions): Explain it.
11490 From Oliver Kiddle and Peter Stephenson.
11492 Have M4sh perform minimal shell sanitizing.
11494 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
11496 (_AS_PREPARE): this new macro.
11498 (AS_INIT): Invoke AS_SHELL_SANITIZE.
11499 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
11501 Adjust Autoconf and Autotest.
11503 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
11504 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
11505 * lib/autotest/general.m4 (AT_INIT): Likewise.
11506 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11507 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
11510 Use this M4sh to generate Autoconf's shell scripts.
11512 * tests/wrapsh.as: New, precursor of wrapsh.in.
11513 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
11514 on Autotest and M4sh.
11515 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
11516 (wrapsh.in): New target.
11517 * bin/autoconf.as: New, precursor of autoconf.in.
11518 (autoconf.in): New target.
11520 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

11523 with indented comments in rules.

11538 directories when descending in a SUBDIRS.
11539 Reported by Ezra Peisach.
11541 2002-04-04 Andreas Schwab <schwab@suse.de>
11543 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
11544 contains no literal separators.
11546 2002-04-03 Akim Demaille <akim@epita.fr>
11548 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
11549 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
11550 Use dnl, not the KILL diversion.
11552 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
11553 (AC_CONFIG_LINKS): here.
11555 Don't use the KILL diversion, as it kills spurious output, which
11556 results in failures being hidden.
11557 Use m4_defn where appropriate.
11558 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
11559 after the second argument.
11561 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
11562 syntax, as it is provided by M4sugar.
11563 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
11565 2002-04-03 Andreas Schwab <schwab@suse.de>

11568 expanded if $# <= 2.

11579 (_AC_COMPILER_OBJEXT): Use them.
11580 Fixes Debian #138666.
11582 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
11584 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
11586 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
11587 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
11588 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
11589 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
11590 (AC_C_CONST): Same.
11591 (AC_C_INLINE): Same.

11600 _AS_MKDIR_P_PREPARE.
11602 2002-03-28 Kevin Ryde <user42@zip.com.au>
11604 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11605 to avoid versions of HP C which don't allow that.
11607 2002-03-27 Paul Eggert <eggert@twinsun.com>
11609 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
11610 (AS_SHELL_SANITIZE): Invoke it.
11611 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

11615 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
11617 2002-03-26 Akim Demaille <akim@epita.fr>
11619 * doc/autoconf.texi (Introduction): The GNATS base moved.
11621 2002-03-25 Paul Eggert <eggert@twinsun.com>
11623 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11624 as POSIX requires, as it doesn't work with Zsh.
11625 * doc/autoconf.texi (Assignments): Document the problem.
11627 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11629 * doc/autoconf.texi (Limitations of Make): Mention more issue
11630 about VPATH, overriding of macros in sub-makes, and handling of
11633 2002-03-21 Paul Eggert <eggert@twinsun.com>
11635 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11636 problem with here-document buffer boundaries.
11638 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11639 when reinvoking the shell, to work around problems with installers
11640 who put strange things like "cd" commands in their environments.
11642 2002-03-19 Akim Demaille <akim@epita.fr>

11656 From Nishio Futoshi.
11658 2002-03-19 Akim Demaille <akim@epita.fr>
11660 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

11664 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
11665 (Limitations of Usual Tools): Add mkdir section.
11667 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11668 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11669 back on AS_DIRNAME to compute prefixes otherwise; this is
11670 roughly what mkinstalldirs does. That way, we need not have
11671 our own filename disassembler. The old disassembler did not
11672 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11674 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11675 Create at_test_all by a series of assignments,
11676 not by a single assignment of a long string. The latter causes ksh
11677 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11678 presumably because of a buffer overrun.
11680 2002-03-14 Paul Eggert <eggert@twinsun.com>
11682 * lib/autotest/general.m4 (at_times_skip):
11683 Renamed from at_times. Now a boolean.
11684 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11685 says 'times: not found'.
11687 2002-03-14 Akim Demaille <akim@epita.fr>
11689 * bin/autoreconf.in (&study_gettextize): New.
11690 (&autoreconf): Handle newest gettextize.

11714 2002-03-11 Andreas Schwab <schwab@suse.de>
11716 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
11717 does not do it if --with-lispdir is given.

11726 subdirectory should exist.
11728 2002-03-08 Akim Demaille <akim@epita.fr>
11730 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11732 2002-03-08 Akim Demaille <akim@epita.fr>
11734 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11735 aliases the actual variables, and modifications of the former
11738 2002-03-08 Akim Demaille <akim@epita.fr>
11740 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11741 because of C-c: have m4 output in tmp files, then mv them.
11743 2002-03-08 Akim Demaille <akim@epita.fr>

11764 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11765 * lib/autoconf/general.m4 (AC_INIT): More informative error
11766 message for LIBOBJ.
11768 2002-03-04 Akim Demaille <akim@epita.fr>
11770 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
11773 2002-03-04 Akim Demaille <akim@epita.fr>
11775 * doc/autoconf.texi (Transforming Names): Equality between target
11776 and host is irrelevant.
11777 (Specifying Names, Canonicalizing): Remove all references to the
11778 backward compatibility hooks. Rather, collect them all into...
11779 (Hosts and Cross-Compilation): this new section.
11780 * doc/install.texi (System Type): Ditto.
11781 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11782 that `--host' implies cross-compilation.
11784 2002-03-04 Akim Demaille <akim@epita.fr>
11786 * doc/autoconf.texi (Evaluation Macros): New.
11787 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11789 (_m4_foreach): Define the variant with immediate evaluation so
11790 that it contains exactly the items, not an expression which
11791 evaluation is the current item.
11792 (m4_re_string, m4_re_word): Don't over quote them.
11794 2002-03-04 Akim Demaille <akim@epita.fr>
11796 Instead of having stacking `shift's evaluated at the end, let
11797 `foreach' loops immediately evaluate them.
11799 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11800 $*. This is the n-th time I change my mind, but hopefully this is
11803 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11805 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11806 it was only a hack for m4_text_wrap.
11807 (m4_car2): Remove, replaced by...
11809 (_m4_foreach): Adjust.
11810 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11811 m4_bpatsubst for clarification.

11860 2002-02-07 Akim Demaille <akim@epita.fr>
11862 Fix Autoconf PR/207:
11863 AC_PREFIX_PROGRAM fails with dashed program names
11865 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
11866 variable when looking for the prefix program.
11867 Now it also works for shell variables.

11902 2002-02-05 Akim Demaille <akim@epita.fr>
11904 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

11921 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

11924 2002-02-05 Akim Demaille <akim@epita.fr>
11926 * bin/autom4te.in (&parse_args): Implement `frozen files are
11927 optional are the sum of the previous files on the command line'.
11928 Also, pass `--reload-state=' on them, so...
11929 (handle_m4): don't.
11930 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
11931 (M4sh): Rely on M4sugar.
11932 (Autotest, M4sh, M4sugar): Use frozen files.
11934 2002-01-31 Akim Demaille <akim@epita.fr>
11936 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

11944 2002-01-30 Akim Demaille <akim@epita.fr>
11946 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one

11948 is now run with GCC only.
11949 * doc/autoconf.texi (Compilers and Preprocessors): New.

11958 2002-01-29 Akim Demaille <akim@epita.fr>
11960 * tests/torture.at (Configuring subdirectories): Use configure.in,
11961 so that aclocal 1.4 works.
11962 Reported by Alexandre Duret-Lutz and Larry Schmitt.
11964 2002-01-28 Akim Demaille <akim@epita.fr>
11966 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
11969 2002-01-28 Akim Demaille <akim@epita.fr>
11971 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11972 AUTOTEST_PATH *after* it was set.
11973 Don't put `.' in the PATH: the user should be precise and `./' if
11974 needed. In addition, given that the test suite does some `cd', if
11975 `.' is in the path, the `tested programs' sections will report
11976 programs found in the test suite's directory, while during the
11977 tests (performed in their own directory), these programs are no

12046 package.m4, since is really depends upon configure.ac, not
12048 * doc/autoconf.texi (testsuite Scripts): Adjust.
12049 * tests/Makefile.am (package.m4): New.
12050 EXTRA_DIST it since its a source.
12052 2002-01-06 Akim Demaille <akim@epita.fr>
12054 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12055 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12056 and PACKAGE_BUGREPORT from here...
12057 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12059 (_AC_INIT_PREPARE): AC_DEFINE these symbols.

12084 2001-12-14 Akim Demaille <akim@epita.fr>
12086 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
12087 trailing files, don't apply `-rf' to files which might not be
12088 created by configure (core, core.*, and *.core), but just `rm -f'.
12089 Suggested by Jonathan Kamens.
12091 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
12093 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

12102 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
12103 abs_srcdir, top_srcpath to abs_top_srcdir.
12104 (_AC_OUTPUT_FILES): Adjust.

12115 2001-12-12 Kevin Ryde <user42@zip.com.au>
12117 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12118 forbidden file descriptors table.
12120 2001-11-26 Akim Demaille <akim@epita.fr>
12122 * bin/autoscan.in (%c_keywords): Build it at top level.

12127 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12128 Remove $filepath, useless.
12129 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12130 variables, they are really part of the tokens.
12131 Split the input line on spaces and then look for tokens.
12132 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12133 because of `lex$U.$(OBJEXT)'.
12134 (&scan_files): Use "@list" instead of join.
12135 * doc/Makefile.am (CLEANFILES): Add *.fns.

12140 Remove, replaced by...
12141 * tests/wrappl.in: Be common for all the Perl executables.
12142 In particular autoscan and autoheader want -I.
12143 * configure.ac: Adjust.
12144 * lib/autoscan/headers: errno.h is portable.
12146 2001-11-26 Akim Demaille <akim@epita.fr>
12148 * bin/autoscan.in (used): New.
12151 2001-11-26 Akim Demaille <akim@epita.fr>
12153 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12155 (&scan_sh_file): Remove a duplicate pattern.

12162 Before, having a line containing the opening of a multi line
12163 comment made the whole line be ignored.
12165 2001-11-26 Akim Demaille <akim@epita.fr>
12167 * doc/autoconf.texi (Using an Autotest Test Suite): New.

12175 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12176 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12178 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12179 top_srcdir, builddir and top_builddir.
12180 Use `at_*dir' relatively to the directory containing the
12181 suite, use `*dir' when relatively to the current group dir.
12183 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12185 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12186 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12187 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12190 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12192 * doc/autoconf.texi (Using System Type): Add an example of `case
12193 $host' usage so people quit using `case $target' everywhere.
12195 2001-11-22 Akim Demaille <akim@epita.fr>
12197 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12198 spotted by Jim Meyering.
12200 2001-11-16 Paul Eggert <eggert@twinsun.com>
12202 This patch implements a `long double' suggestion by Oliver Kiddle.
12204 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12205 static, to catch errors if the value isn't known at compile-time
12206 and the compiler supports dynamic arrays. Change its name from
12207 `_array_' to `test_array' to avoid potential name clashes.
12208 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12209 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12210 better than double. Catch a bug in GCC 2.95.2 x86.
12211 * doc/autoconf.texi (C Compiler): Document the above.
12214 2001-11-13 Akim Demaille <akim@epita.fr>
12216 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12218 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12220 2001-11-13 Akim Demaille <akim@epita.fr>
12222 * lib/autotest/general.m4 (AT_INIT): After having run the test
12223 group, go back to the initial directory, not to at_suite_dir.
12225 2001-11-13 Akim Demaille <akim@epita.fr>
12227 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12228 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12229 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12231 (AT_CHECK_CONFIGURE): Use absolute paths.
12232 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12233 The problem is still the old one: there is no means in M4 (that I
12234 know about) to create a defining macro, because there is no means
12235 to create `$1' etc., therefore, the defining macro ``swallows''
12236 all the arguments meant to the defined macro.
12238 2001-11-13 Akim Demaille <akim@epita.fr>
12240 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12241 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12243 * tests/aclocal.m4: Remove, as it is no longer used.
12245 2001-11-13 Akim Demaille <akim@epita.fr>
12247 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12248 variable names when referring to a single test group, or to
12249 `suite' when referring to the whole test suite.
12250 `at_last_test' is removed: m4 compute at_format itself.
12251 (at_stdout, at_stder1, at_stderr): New variables.
12252 (AT_CHECK): Use them.
12254 2001-11-13 Akim Demaille <akim@epita.fr>
12256 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12258 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12259 Do it as soon as a test fails, don't wait till the end of the test
12261 Don't remove $as_me.[0-9]*, since these files no longer exist.
12263 2001-11-13 Akim Demaille <akim@epita.fr>
12265 * tests/tools.at: Use absolute paths, since we are no longer run
12268 2001-11-13 Akim Demaille <akim@epita.fr>
12270 Now that tests are running in their own private dir, there is no
12271 need to list the files to remove at the end of tests groups.
12273 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12274 (AT_data_files, at_data_files): Remove.
12275 (AT_CLEANUP, AT_DATA): Simplify.
12277 Remove the group dir if !debug && !failed.
12278 * tests/atspecific.m4: Adjust.
12280 2001-11-13 Akim Demaille <akim@epita.fr>
12282 Start a new layout for Autotest: `testsuite' creates
12283 `testsuite.dir' in which the at-check-line etc. files are to be
12284 found, and `testsuite.dir/003' where the test group 3 is run.
12286 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12287 at_check_line_file, at_format, at_test_normalized, at_group_dir
12289 Create the directories.
12290 Use absolute paths for at- files.
12291 (AT_CHECK): Adjust.
12293 2001-11-11 Michael Matz <matz@kde.org>
12295 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12297 (m4_car): Properly quote arguments.
12299 2001-11-13 Akim Demaille <akim@epita.fr>
12301 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12302 with stricter rules on LIBOBJS.
12304 2001-11-12 Paul Eggert <eggert@twinsun.com>
12306 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12307 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12310 2001-11-12 Akim Demaille <akim@epita.fr>
12312 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12314 2001-11-12 Akim Demaille <akim@epita.fr>

12317 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12318 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12319 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12320 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12321 specify to what the macro should be defined (typically to 1).
12323 2001-11-12 Akim Demaille <akim@epita.fr>
12325 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12328 2001-11-12 Akim Demaille <akim@epita.fr>
12330 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12331 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12332 definition used by Automake where LEX is +/- "${missing} lex" and
12333 `missing' itself contains variables.
12335 2001-11-12 Akim Demaille <akim@epita.fr>
12337 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12338 Now that M4sh pushes BODY, the comments were output at the end of
12341 2001-11-08 Akim Demaille <akim@epita.fr>
12343 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12344 that we can trace macros from aclocal.m4.
12345 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12346 obsoleted, and redirect to the former anyway.
12347 Reported by Ralf Corsepius.
12349 2001-11-08 Akim Demaille <akim@epita.fr>
12351 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12352 processed only if present.
12353 * tests/torture.at (Configuring subdirectories): Use autoreconf
12354 instead of successive calls to autoconf.
12355 Add a nonexistent subdirectory to exercise the patch above.
12356 Reported by Ralf Corsepius.
12358 2001-11-08 Kevin Ryde <user42@zip.com.au>
12360 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12361 doesn't accept .S files.

12368 * bin/autom4te.in (warn_forbidden): New.
12369 (handle_output): Use it.
12370 Read m4_pattern_forbid with messages.

12374 * bin/autom4te.in (--normalize): Remove.
12375 * lib/autom4te.in: Adjust.
12377 2001-11-05 Akim Demaille <akim@epita.fr>
12379 * tests/Makefile.am (testsuite): Rename this target as...
12380 ($(TESTSUITE)): this.
12383 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12385 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12386 the --prefix option, also remove it's argument.
12388 2001-11-05 Akim Demaille <akim@epita.fr>
12390 * doc/autoconf.texi (testsuite Invocation): Update.
12391 (Writing testsuite.at): Update.

12400 (&file_name_is_absolute): New, wrappers around routines from
12402 Use and export them.
12403 (&find_configure_ac): Optionally take a directory where to look at.
12404 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12406 Default @ARGV to `.', not find_configure_ac.
12407 (&autoreconf): Argument is a directory.
12408 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
12409 * doc/autoconf.texi (autoreconf Invocation): Update.
12411 2001-11-03 Akim Demaille <akim@epita.fr>

12418 Don't look for aclocal flags if we already know aclocal is not
12420 Move aclocal.m4t only if it exists.
12421 Reported by Ezra Peisach.
12423 2001-11-03 Akim Demaille <akim@epita.fr>
12425 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12426 passed on command line, defaulting to ./configure.ac if present.
12427 (&maybe_autoreconf, File::Find): Remove, unused.
12428 (&autoreconf): If autoconf is not used, don't try to trace.
12430 2001-11-02 Akim Demaille <akim@epita.fr>

12447 Don't run aclocal when aclocal.m4 is not from aclocal.
12449 Don't run libtoolize and gettextize if --install is not given.
12451 2001-11-01 Paul Eggert <eggert@twinsun.com>
12453 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
12454 be invoked before _AS_LINENO_PREPARE.
12455 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
12456 than character ranges.
12458 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
12459 invoking AS_BASENAME. Set the locale variables to 'C' if
12460 possible, as POSIX requires this to get the traditional
12462 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12464 2001-10-31 Paul Eggert <eggert@twinsun.com>
12466 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12467 with {}, as that triggers a bug in Bash 2.05.
12469 (_AS_LINENO_PREPARE): Use Sed rather than
12470 Awk. Fix the sed prepass to work even if there are multiple
12471 instances of $LINENO on the same line. Do not substitute for
12472 other variables like $LINENOT. Do not check file dates; such a
12473 check is unreliable on sufficiently fast machines, and removing
12474 the check makes the code simpler and more reliable. Check for
12475 output and chmod failures.
12477 * doc/autoconf.texi (Special Shell Variables): Document
12480 2001-10-31 Akim Demaille <akim@epita.fr>

12492 2001-10-26 Paul Eggert <eggert@twinsun.com>
12494 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12495 lib/Autom4te/Struct.pm:
12496 Require Perl 5.005_03 instead of just 5.005, as some tests fail
12499 * doc/autoconf.texi (Special Shell Variables): Document some
12500 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
12502 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
12503 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

12522 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
12523 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12524 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12525 POSIX decided to standardize on the int flavor of strerror_r.
12526 Always do char* test, as there's no reason not to.
12527 Assign to a char* var, to catch strerror_r that returns int*.
12529 * doc/autoconf.texi (Particular Functions):
12530 Document the above changes. Also, document the fact that
12531 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

12555 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12557 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12558 `intl' is already present, as it refuses unless --force.
12559 (&parse_args): Use -I, --include instead of the old Autoconf
12561 ($localdir, $autoconf_dir): Remove.
12563 (&maybe_autoreconf): New, to preserve $_ for File::Find.
12565 2001-10-19 Jens Petersen <petersen@redhat.com>

12586 configure.ac being studied.
12588 2001-10-18 Paul Eggert <eggert@twinsun.com>
12590 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

12595 (AS_BASENAME_EXPR): New macro.
12596 (AS_BASENAME_SED): Do not assume GNU sed semantics.
12597 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
12598 and fall back on 'sed' only if the other two fail. This makes
12599 AS_BASENAME act more like AS_DIRNAME.
12600 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
12601 contains white space.
12602 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
12603 Use AS_DIRNAME, since I think it's now DOS-friendly.

12657 * lib/Autom4te/General.pm: does.
12659 2001-10-08 Akim Demaille <akim@epita.fr>

12752 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

12837 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

12978 * tests/Makefile.am (package.m4): Remove.
12980 2001-09-22 Akim Demaille <akim@epita.fr>
12982 Rely on `$LINENO' when possible instead of `__oline__'.

12985 `$LINENO' support replacement when not supported.
12986 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

13031 arguments. Fixed a typo.
13033 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13035 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
13036 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.

13053 2001-09-19 Akim Demaille <akim@epita.fr>
13055 * lib/autotest/general.m4: Englishoes.
13056 From Tim Van Holder and Alexey Mahotkin.
13058 2001-09-18 Paul Eggert <eggert@twinsun.com>
13060 * doc/autoconf.texi (Common Shell Constructs): New node,
13061 documenting AS_DIRNAME.
13062 (Limitations of Usual Tools): Refer to it when discussing dirname.
13063 Also, update discussion of POSIX standard to reflect latest draft.
13065 * lib/autoconf/c.m4:
13066 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13068 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13069 Do not pass a first argument with leading '-'
13070 to expr, by parenthesizing initial integers that might be negative.
13072 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
13073 now merely checks whether it is an error to pass an argument
13076 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
13077 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
13078 whether it is a (compile-time) error to pass an argument to
13079 getpgrp. This simpler test supports the revised documentation,
13080 and is all that AC_FUNC_GETPGRP's users really need.
13082 2001-09-18 Akim Demaille <akim@epita.fr>
13084 * doc/autoconf.texi (Limitations of Make) <$<>: New.

13094 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
13096 Add test for AS_BASENAME.
13097 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13098 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13099 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13100 * tests/base.at: Fixed the expected responses. The old ones were
13102 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13103 the documentation claims it should (and how it behaved in 2.13).
13105 2001-09-18 Akim Demaille <akim@epita.fr>
13107 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13108 the AC_CONFIG_COMMANDS invocation.
13109 This also solves the name clash problems.
13110 Don't set the package's ID.
13111 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13112 No longer to be shipped.
13113 (version.in): Remove.

13115 * lib/autoconf/status.m4: Adjust.
13116 Use `m4_PACKAGE_STRING'.
13117 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13118 the only optional argument is the name of the test suite.
13119 Expect `package.m4' to define the package signature.
13120 * lib/autom4te.in (Autotest): Add `package.m4?'.
13121 * tests/Makefile.am (package.m4): New.
13122 * tests/suite.at: ifnames is a victim.
13124 2001-09-18 Akim Demaille <akim@epita.fr>
13126 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
13127 AC_LIBSOURCE, AC_CONFIG_FILES.
13128 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13129 program version string doesn't match the package's.
13130 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

13141 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13142 Always include <stdio.h> and <stdlib.h>. Evaluate
13143 the expression in an extra function before these includes. Call
13144 fprintf "%d" only after ensuring the argument is of type 'int'.
13145 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13147 2001-09-17 Paul Eggert <eggert@twinsun.com>
13149 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13150 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13151 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13152 when they don't exist.
13154 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13155 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13158 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13159 version with the version used by fileutils 4.1, except use
13160 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13163 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13165 2001-09-13 Akim Demaille <akim@epita.fr>

13205 * lib/autotest/general.m4 (AT_INIT): Create and remove
13206 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
13207 test suites can cohabit.
13209 2001-09-13 Akim Demaille <akim@epita.fr>
13211 * tests/mktests.sh: Don't output banners for empty test files.

13263 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

13266 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

13317 2001-09-05 Akim Demaille <akim@epita.fr>
13319 Be ready to handle filenames as stupid as `dnl.at', for if even
13320 the maintainer is dumb enough to do that...
13322 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13323 excellence in M4 quotation: consider `__file__' is active.
13325 And BTW, when invoking m4, pass the --include in the right order:
13328 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

13356 New, extracted from main.
13357 Use IO::File wherever possible.

13402 to m4sugar was lacking!
13404 2001-08-31 Akim Demaille <akim@epita.fr>
13406 * man/Makefile.am (.x.1): We really have to pass
13407 autom4te_perllibdir.
13409 2001-08-31 Akim Demaille <akim@epita.fr>
13411 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

13418 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.

13462 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
13463 `autoheader: `config.hin' is created'.
13464 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
13466 2001-08-31 Akim Demaille <akim@epita.fr>

13474 Map --localdir, --autoconf-dir onto it.
13475 Forward autom4te's options instead of interpreting them.

13477 There is no such envvar since the inception of autom4te.cfg.

13500 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

13505 * tests/atlocal.in: Remove all the obscure envvar manipulations.
13507 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
13508 indeed related to running the test suite, while passing
13509 --autoconf-dir and others is related to running non installed
13510 Autoconf executables. So don't do that, leave it to...

13512 * tests/autoscan: New.
13513 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

13530 Suggested by Paul Eggert.
13532 2001-08-29 Akim Demaille <akim@epita.fr>

13537 2001-08-29 Akim Demaille <akim@epita.fr>

13559 foo=`(command) 2>/dev/null`

13799 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
13800 * NEWS, README, README-alpha, TODO, tests/README: This package is
13801 `Autoconf', not `autoconf' (the executable).

13857 * lib/autoconf/general.m4, lib/autoconf/specific.m4,

14009 is in the src tree.

14076 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
14078 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
14079 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
14080 * doc/autoconf.texi (C Compiler Characteristics): Update

14086 magic values from an object file when cross-compiling.
14087 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
14089 2001-08-10 Akim Demaille <akim@epita.fr>
14091 * bin/autom4te.in (&handle_output): Don't use `grep' with side
14093 Suggested by Russ Allbery.
14095 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14097 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14098 current $prefix to the sub-configures.
14100 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14102 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14103 extension (needed on BeOS). Reported by Guido van Rossum.
14105 2001-08-09 Akim Demaille <akim@epita.fr>
14107 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14109 2001-08-07 Akim Demaille <akim@epita.fr>
14111 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14113 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14114 No need to remove the files before and after the each test, before
14115 each test and at the end of the suite is enough.
14116 Display only the children `times', not the shell's.
14117 If the test failed or was skipped, at-times is not available.
14119 2001-08-07 Akim Demaille <akim@epita.fr>
14121 Always produce testsuite.log, including when there are no
14122 failures. This helps getting information on skipped tests, and
14123 duration of the tests. Err, implement the latter btw.
14125 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14126 Dump information on the first run of each test.
14127 (AT_CLEANUP): Create `at-times' containing the duration of the
14130 2001-08-07 Akim Demaille <akim@epita.fr>
14132 The use of `dumpstat' revealed that `len' was used although it
14133 should not. m4_text_wrap was using it, but in the Autoconf world
14134 where it is legal. Hence (i) test M4sh in its own world, not
14135 Autoconf's, and (ii), ahem, fix the bug :)
14137 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14138 does not like `' instead of [].
14139 (AT_INIT): Forbid `^_?AT_'.
14140 And don't output such tokens.
14141 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14142 `script.as', and `autom4te.cache'.
14143 Remove `empty' and `macro' which are no longer used.
14144 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14145 * tests/m4sugar.at: Use it.
14146 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14148 2001-08-07 Akim Demaille <akim@epita.fr>

14154 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14156 2001-08-04 Akim Demaille <akim@epita.fr>
14158 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14159 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14161 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14162 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14163 (AC_F77_MAIN): Likewise.
14165 2001-08-04 Akim Demaille <akim@epita.fr>
14167 Don't rely on M4sugar outputting the patterns in files, since we
14168 might process the output _without_ running m4, hence without these
14171 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14172 * bin/autom4te.in (@Request::includes): Remove, unused.
14173 (@Request::source): Rename as...
14174 (@Request::input): this.

14179 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14181 2001-08-04 Akim Demaille <akim@epita.fr>
14183 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14184 autoconf', i.e., in addition to caching traces, cache the output.
14186 * bin/autom4te.in (Request::cache): Rename as...
14187 (Request::id): this.
14188 ($cache, $icache, $tcache, $ocache): New.
14189 (&handle_m4): Save M4 output in the cache instead of $tmp.

14195 2001-08-04 Akim Demaille <akim@epita.fr>
14197 * bin/autom4te.in ($force): New.
14198 (&parse_args, &print_usage): -f, --force is a new option.
14199 (&handle_output): CPP directives might have spaces after `#'.
14200 (&parse_args): The first file only can be frozen.
14202 2001-08-04 Akim Demaille <akim@epita.fr>
14204 Don't let autom4te compute the `include' traces several times:
14205 first check that the trace cache file is up to date, and then
14206 compare its timestamp with that of the output.
14208 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14209 the preamble. Don't require 5.005 as Autom4te::General does it,
14210 and better yet (use `use', not `require'!).
14211 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14212 Class::Struct as Autom4te::Struct.
14213 * lib/Autom4te/General.pm (File::stat): Use it.
14214 (&mtime): New, export it.
14215 * bin/autom4te.in: Use it.
14216 Declare `$req' is invalid if it is outdated.
14217 Don't declare it valid before saving it if something went wrong.
14219 2001-08-04 Akim Demaille <akim@epita.fr>

14222 must be proposed to the users.

14267 (m4_divert_pop): Dump the whole diversion stack when a diversion
14269 * bin/autom4te.in (&handle_output): Remember of the first
14270 occurrence of a possibly undefined macro, not the last.

14272 the appear in the output.
14273 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
14274 * tests/tools.at (autoconf: forbidden tokens, basic)
14275 (autoconf: forbidden tokens, exceptions): No longer sort
14276 autoconf's stderr, as it is now deterministic.
14277 Check that `dnl' is caught.

14299 `END', as `Autom4te::General::END' will be triggered.
14300 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
14301 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
