3 Fix some whitespace tests on cygwin.
4 * tests/tools.at (autom4te and whitespace in file names): Restore
5 font-lock. Create $TMPDIR before it might be used.
7 Fix spurious testsuite failure with M4 1.4.11.
8 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
11 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
12 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
13 (m4_require): Avoid extra macro calls.
15 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
17 * tests/torture.at (srcdir): Fix quoting.
19 Do not pass top_srcdir to configure scripts in testsuite.
20 * tests/autotest.at (srcdir propagation): Copy install-sh to
22 (my only test): Drop setting of `top_srcdir'.
23 * tests/base.at (Input/Output): Likewise.
24 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
25 config.guess, and config.sub to test source tree.
26 Drop AC_CONFIG_AUX_DIR setting.
27 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
28 * tests/torture.at (Substitute a 2000-byte string): Drop
29 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
30 (Substitute a newline, datarootdir workaround): Likewise.
31 (Define a newline): Adjust for linenumber changes in configure.ac.
32 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
34 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
35 if `pwd` contains whitespace.
37 Quote $abs_top_srcdir in tests.
38 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
39 * tests/tools.at (Syntax of the shell scripts): Likewise.
41 * tests/m4sh.at (LINENO): Quote $0.
43 Fix testsuite program wrapper for whitespace in `pwd`.
44 The problem here is that the usual mantra is that command
45 variables can contain arguments, thus we cannot just escape
46 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
47 $top_builddir/tests directory early in $PATH, so that the
48 wrappers are found by their plain name.
49 * tests/wrapper.as: Put $testdir early in $PATH.
50 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
52 Proper config.status --file/--header and $srcdir escaping.
53 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
54 characters in $ac_file_inputs.
55 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
57 * tests/torture.at (datarootdir workaround): Adjust.
58 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
60 Fix Autotest for whitespace in `pwd`.
61 * lib/autotest/general.m4 (AT_INIT)
62 <at_func_create_debugging_script, Driver Loop>:
64 * tests/autotest.at (whitespace in absolute testdir): New test.
66 * lib/autom4te.in: Quote @datadir@.
68 Proper file name escaping in Autoconf programs and Perl modules.
69 This includes escaping of characters special to the shell
70 as well as special to Perl, e.g., leading `<' or `>'.
71 For example, when $file starts with `>', `open ">$file"'
72 wrongly tries to append to a different file.
73 * bin/autoconf.as: Fix quoting for autom4te options.
74 * lib/Autom4te/General.pm (shell_quote): New function, taken
75 from coreutils, written by Jim Meyering.
77 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
79 * bin/autoreconf.in (parse_args): Likewise.
80 * bin/autoscan.in (main): Likewise.
81 * bin/autoupdate.in (main): Likewise.
82 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
83 * bin/ifnames.in: Likewise, XFile usage fixes.
84 * tests/tools.at (autom4te and whitespace in file names): Extend
85 test. Test twice, with special characters allowed on w32, and the
86 rest. Test leading and trailing whitespace, for `open_quote'.
87 (autotools and whitespace in file names): New, analogous test.
88 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
89 by Russ Allbery and Eric Blake.
92 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
93 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
94 * lib/Autom4te/FileUtils.pm (open_quote): New function.
95 (update_file, contents): Use it.
97 * Makefile.am (autom4te-update): Rewrite for git.
99 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
101 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
104 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
105 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
107 2007-12-04 Eric Blake <ebb9@byu.net>
109 Manually resync with gnulib, since 'make cvs-update' no longer works.
110 * build-aux/config.guess: New upstream version.
111 * build-aux/config.sub: Likewise.
113 When using older automake, don't downgrade build-aux/texinfo.tex.
114 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
115 * doc/Makefile.am (TEXINFO_TEX): Add.
117 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
119 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
120 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
121 #undef as this runs afoul of our new way of creating config.h.
122 Problem reported by Jim Meyering in
123 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
125 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
127 Fix autom4te for unusual characters in input file names.
128 * bin/autom4te.in (files_to_options): Quote active characters
130 * tests/tools.at (autom4te and white space in file names):
133 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
134 Document that Tru64 awk always splits $0.
136 2007-11-24 Stepan Kasal <kasal@ucw.cz>
138 * lib/autotest/general.m4 (AT_INIT): Do not extract the
139 `#AT_STOP_...' line at the end of each test.
141 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
143 * lib/autotest/general.m4 (AT_INIT): For awk line number
144 extraction script, ensure `$at_group' has a defined value
145 even for the empty set, and properly quote its usage inside
148 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
150 * doc/autoconf.texi (Shell Functions): New chapter. Document
151 IRIX sh $0 issue in functions, move content from ...
152 (Portable Shell): ... here.
153 (Shell Script Compiler): Note that shell functions are not
154 totally unportable any more.
156 2007-11-22 Stepan Kasal <kasal@ucw.cz>
157 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
159 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
160 extracting the line numbers of the last needed test.
162 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
164 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
167 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
169 Fix IRIX testsuite debugging failures: $0 in functions.
170 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
171 Do not use $0 inside a function, as IRIX sh will set that to the
172 function name rather than the script invocation name.
174 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
175 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
177 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
178 to extract test scripts.
179 (AT_INIT): Extract and cache test script line numbers.
181 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
183 * lib/autotest/general.m4: Revert 2007-11-15 patch and
184 subsequent fixups; the awk -> here-document conversion trashes
185 performance too much with AIX sh.
187 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
189 * tests/local.at: Do not test m4, perl with AT_TESTED.
191 Diagnose and guard against write errors dealing with config.status.
192 The general idea is this: all write failures from `configure'
193 writing `config.status' are indicated by $ac_write_error, which
194 is only checked at the end. This is safe because config.status
195 code is not executed before the file is complete. Other write
196 failures, be they inside config.status, or in sub shell/awk
197 scripts spawned from configure or config.status, typically need
198 earlier checking, as their results are used right afterwards.
199 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
200 before writing config.status, check afterwards.
201 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
202 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
203 Set `ac_write_error' for write failures to config.status. Barf
204 upon write failures to temporary files.
205 Adjust note about closing and reopening the here-document.
206 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
207 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
208 reopening the here-document.
209 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
210 Ensure `ac_write_error' does not escape into config.status.
211 Also, add a couple of code paths not yet exercised in the test
212 suite: a config file with input from stdin, and a config header
214 Suggestion for catching write errors by Bruno Haible.
216 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
218 Avoid error with Tru64 awk and testsuite lines with many words.
219 * lib/autotest/general.m4 (AT_INIT): In the awk script that
220 reads the testsuite, set the field separator to an unusual value,
221 in order to not run over the limit of 199 fields. Tru64 4.0D awk
222 even splits the input if $i, i>0, was never accessed in the script.
224 Revert 2007-10-17 change.
225 * TODO: Multiline args in config files and headers mean something
226 different and are not fixed, see
227 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
228 Report by Stepan Kasal.
230 * doc/autoconf.texi (Generic Programs): Fix typo.
232 2007-11-16 Stepan Kasal <kasal@ucw.cz>
234 AC_*_TOOL does not canonicalize the prefix
235 * doc/autoconf.texi (Generic Programs): Do not say that
236 the *_TOOL macros canonicalize, they simply use the `host_alias'.
238 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
240 Diagnose write errors in config.status instantiations.
241 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
242 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
244 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
245 Extend test to also check for some write error failures, using...
246 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
247 Report by Bruno Haible.
250 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
252 (_AT_CHECK): Use less indentation, to save space.
254 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
256 Add witness macro for @top_build_prefix@ substitution.
257 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
258 (_AC_OUTPUT_FILE): Mention it here.
260 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
261 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
263 * lib/autotest/general.m4 (at_func_test): Remove.
264 (AT_INIT): Pre-extract test groups into separate files.
265 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
266 Remove at-test-source files together with the $at_group_dir.
267 * tests/autotest.at (Long test source lines): New test.
269 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
271 Shell functions and variables may share a namespace.
272 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
275 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
277 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
280 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
282 * lib/autoconf/status.m4: Fix a couple of comment typos.
284 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
286 2007-11-13 Jim Meyering <meyering@redhat.com>
288 Clean up the rule to create "expr".
289 * tests/Makefile.am (expr): Don't redirect directly to target.
290 Redirect just once, not for each echo statement.
291 Use $@, not literal "expr".
293 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
295 Don't worry about preprocessor when testing long long.
296 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
297 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
298 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
299 These no longer check for preprocessor flaws.
300 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
301 Do not check for preprocessor flaws.
303 2007-11-13 Jim Meyering <meyering@redhat.com>
305 Adapt dependencies, now that a version change doesn't modify configure.ac
306 * GNUmakefile: Remove "make clean" kludge.
307 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
309 Don't redirect directly to target.
310 Use $@, not literal "version.m4".
312 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
314 * doc/autoconf.texi (Making testsuite Scripts): Document
315 ":;{" shorthand as in previous patch.
317 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
319 * doc/autoconf.texi (Limitations of Builtins): Document problem
320 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
322 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
324 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
326 2007-11-12 Jim Meyering <meyering@redhat.com>
328 Add more non-srcdir build support.
329 * GNUmakefile (dummy): Split a long line.
330 Add -v option to autoreconf invocation.
332 Remove the autoreconf-provided INSTALL, so that we regenerate it.
333 * GNUmakefile (dummy): Remove INSTALL.
335 Remove racy commands to build scripts in bin/ and tests/.
336 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
337 are guaranteed to be built, remove the rules that tried to build
338 them. Before, with a parallel build, these rules could lead to
339 two processes writing tests/wrapper.in concurrently.
341 Build in man/ only *after* building in bin/ and tests/.
342 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
343 in both bin/ and tests/.
345 Accommodate non-srcdir build-from-checkout.
346 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
347 Use git's --git-dir=$srcdir/.git option.
348 Add quotes, in case tarball_version_file contains shell meta-characters.
349 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
350 * configure.ac: Pass "." to git-version-gen.
352 Avoid spurious test failures due to version skew.
353 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
355 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
357 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
358 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
359 Remove conftest.dSYM directory.
360 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
361 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
362 Remove `conftest.*' recursively.
363 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
364 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
366 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
368 Report and analysis by Jeff Squyres and Peter O'Gorman.
370 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
372 Fix typos in variable names.
373 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
375 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
377 Document that $((expression)) is not portable.
378 * doc/autoconf.texi (Shell Substitutions): Here.
380 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
382 Ignore configure --help* errors due to LINENO-impaired shells.
383 * tests/torture.at (Configuring subdirectories, Deep Package):
384 In the --help* tests in read-only trees, make `.' temporarily
385 writable again for the `stderr' file, and ignore errors due to
386 the attempt to write configure.lineno.
387 Report by Patrick Welche.
389 2007-11-10 Jim Meyering <meyering@redhat.com>
391 Generate package.m4 in build-dir, not srcdir.
392 * tests/Makefile.am (package.m4): Adjust target.
393 Don't redirect directly to $@.
394 (CLEANFILES): Add package.m4.
395 ($(TESTSUITE)): Depend on just-built package.m4, not the one
397 When running $(AUTOTEST), search "." before searching $(srcdir).
399 Avoid a race condition that would make parallel "distclean" fail.
400 * tests/Makefile.am (distclean-generic): Replace the default,
401 automake-provided rule with an identical one, but with an additional
402 dependency on distclean-local. Simply adding the dependency would
403 cause automake not to emit the rule at all.
404 * BUGS: Building with -jN works, now.
406 Distribute git-version-gen.
407 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
408 since GNUmakefile is distributed, and requires it for dist* rules.
410 Remove two more generated files from version control.
411 * INSTALL: Remove generated file.
412 * lib/autoscan/autoscan.list: Remove generated file.
414 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
416 * GNUmakefile (PATH): Remove stray apostrophes; they become
417 part of PATH, which isn't wanted here.
419 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
421 New config files output variable `top_build_prefix'.
422 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
424 * doc/autoconf.texi (Preset Output Variables): Document it.
426 Report by Bob Friesenhahn.
428 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
429 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
430 function, to parametrize arithmetic with expr vs. the shell.
431 Use it where possible.
432 Suggestion by Benoit Sigoure.
434 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
436 Adjust the documentation of autotest WRT atlocal.
437 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
438 when using Automake, to write a rule to produce atlocal, since it's
439 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
440 distributed, not atconfig.in.
442 2007-11-04 Eric Blake <ebb9@byu.net>
444 Update list information.
445 * README: Mention new autoconf-commit list.
446 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
448 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
450 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
452 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
454 * build-aux/.gitignore: Ignore mkinstalldirs.
456 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.

460 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
461 * build-aux/git-version-gen: This syncs from coreutils.
463 Adjust the build procedure so "make check" works reliably.
464 * README-hacking: Include an extra step between "make" and
465 "make check" to ensure that the latter passes.
467 Use just-built tools, when possible.
468 * GNUmakefile (PATH): Set and export here, ...
469 (dummy): ... rather than here.

504 * build-aux/missing: Remove file.
505 * build-aux/mdate-sh: Remove file.
506 * build-aux/.gitignore: New file.
507 Suggestion from Ralf Wildenhues.
509 2007-11-03 Eric Blake <ebb9@byu.net>
511 Adjust version comparison to account for git snapshot numbers.

518 2007-10-30 Bruno Haible <bruno@clisp.org>
520 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
521 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
522 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
523 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in

536 so that we use just-built tools when they're available.
537 Suggestions from Ralf Wildenhues.
539 2007-10-28 Jim Meyering <meyering@redhat.com>
541 Make inter-release --version output more useful.
543 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
544 which indicates that it is built using the 19th change set
545 (in _some_ repository) following the "v2.61a" tag, and that 58dd
546 is a prefix of the commit SHA1.
547 * build-aux/git-version-gen: New file.
548 * configure.ac: Run it to set the version.
549 (AM_INIT_AUTOMAKE): Don't check NEWS here.
550 * Makefile.am (dist-hook): Arrange so that .version appears only
551 in distribution tarballs, never in a checked-out repository.
552 * .gitignore: Add .version here, too. Just in case.
553 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
554 not configure.ac, now that the version number changes automatically.
556 Ensure that $(VERSION) is up to date for dist-related targets.
557 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
558 git-version-gen doesn't match $(VERSION), but only for dist targets.

1861 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1862 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

2029 http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00157.html
2031 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2033 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
2034 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2035 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2036 substitution will still be done by the special code.
2037 Report by Jim Meyering.
2039 * doc/autoconf.texi (File System Conventions): Mention that
2040 $PATH_SEPARATOR is for the build system only.
2041 Report by Keith Marshall.
2043 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2045 * doc/autoconf.texi (Setting Output Variables): Mention that
2046 all non-NUL characters are ok in substituted values.
2047 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
2048 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
2049 carriage return for $AWK, needed for BSD awk.
2050 * tests/torture.at (Substitute and define special characters):
2051 Test all 8 bit non-NUL characters.
2052 Report against Automake by Patrick Welche.
2054 2007-01-15 Stepan Kasal <kasal@ucw.cz>
2056 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
2058 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2060 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2061 early on the reader side, drop stderr of the input to avoid
2062 `broken pipe' error output; this may happen even with shell
2063 builtin `echo' of some bash versions. Reports by Ian Macdonald
2064 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2066 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2068 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
2069 separate items of `ac_user_opts', to avoid long lines.
2070 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
2072 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2074 * doc/autoconf.texi: Fix some typos.
2076 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
2078 Fix some wording problems noted by Paolo Bonzini in:
2079 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2080 * doc/autoconf.texi (Signed Overflow Examples): Give more
2081 discussion about the allow_superuser_privileges example,
2082 and change it a bit to make things clearer.
2083 (Optimization and Wraparound): Clarify whether the compiler
2084 will generate an infinite loop for the example derived from
2085 Autoconf's mktime test.
2086 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2087 Also, clarify unsigned multiplication overflow.
2089 2007-01-04 Eric Blake <ebb9@byu.net>
2091 * bin/Makefile.am (RELEASE_YEAR): New macro.
2092 (edit): Use it to supply correct copyright year to scripts.
2093 * bin/autoconf.as (version): Use it.
2094 * bin/autoheader.in ($version): Likewise.
2095 * bin/autom4te.in ($version): Likewise.
2096 * bin/autoreconf.in ($version): Likewise.
2097 * bin/autoscan.in ($version): Likewise.
2098 * bin/autoupdate.in ($version): Likewise.
2099 * bin/ifnames.in ($version): Likewise.
2101 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2103 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2104 feedback. The most important changes document what happens when
2105 you convert an out-of-range value to a signed integer type, and
2106 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2109 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2110 rewrite, taking notions from the recent discussion on the gcc and
2111 autoconf mailing lists; please see
2112 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2113 and follow the many links.
2114 (Integer Overflow Basics, Signed Overflow Examples):
2115 (Optimization and Wraparound, Signed Overflow Advice):
2116 (Signed Integer Division): New sections.
2118 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2120 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2121 preprocessor macro arguments in traced name.
2122 * doc/autoconf.texi (Defining symbols): Document longstanding
2123 support for AC_DEFINE-ing macros with arguments, and document
2124 behavior when the same variable has multiple AC_DEFINEs.
2125 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2126 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2127 macros directly, giving much shorter and simpler code.
2129 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2131 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2132 space before "$ac_configure_args" to prevent a 'config.status
2133 --recheck' failure if ac_configure_args doesn't contain a leading
2134 space. This works around a problem with the XEmacs configure.ac,
2135 which uses the (undocumented) ac_configure_args variable
2136 inconsistently with Autoconf.
2138 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2140 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2141 Include <limits.h>, and use its INT_MAX to rewrite the
2142 j loop so that it does not overflow 'int'. Problem reported by
2144 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2145 Play it safe by shifting left by 1 rather than multiplying by 2,
2146 as GCC is less likely to optimize this away when the value
2147 is signed (when it assumes overflow leads to undefined behavior).
2148 Also, don't assume time_t uses two's complement.
2150 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2152 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2153 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2154 dumps core on it. Report by Tim Rice.
2156 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2158 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2159 --disable-option-checking to --help output even when
2160 AC_PRESERVE_HELP_ORDER is not used.
2161 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2162 --with argument, rather than argument with [-.] replaced by
2164 * NEWS: Fix typo in previous change; the news was in the
2167 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2169 * NEWS: Warnings are now generated by default for unknown
2170 --enable-* and --with-* options.
2171 * doc/autoconf.texi (Option Checking): Renamed from
2172 (Configure Option Checking). Tighten up the wording a bit.
2173 (External Software, Package Options): Cross-reference to Option
2174 Checking, and use this to shorten our section.
2175 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2176 "$x" to test "x$foo" != x.
2177 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2178 Don't warn if $enable_option_checking is "no".
2179 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2180 ac_unrecognized_opts to the empty string.
2181 Don't echo the unrecognized opts, as this might mishandle
2182 backslashes or leading -.
2183 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2184 usage next to the other --disable-FEATURE options in the
2187 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2189 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2190 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2191 Print warning for unrecognized --with and --enable options
2192 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2193 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2194 Disable option checking when subdirs are configured.
2195 (AC_OUTPUT): If warnings are enabled, print warning about
2196 unrecognized --with and --enable options at the end of
2197 the configure output (as well as at the beginning).
2198 * doc/autoconf.texi (Option Checking): New node.
2199 Document new option warning functionality.
2201 2006-12-16 Eric Blake <ebb9@byu.net>
2203 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2204 * NEWS: Start news for current version.
2206 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2208 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2209 Define HAVE_GETMNTENT to 1, not to the empty string.
2210 Problem originally reported by Jochen Friedrich in
2211 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2213 This change prompted by a problem report by Andrey Simonenko in
2214 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2215 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2216 object-like macros only, in the traditional portable character
2218 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2219 Warn about attempts to define things that are not identifiers.
2220 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2221 awful hack that AC_DEFINEd macro names containing parentheses.
2223 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2225 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2226 too drastic, even if Texinfo in theory requires it for info mode.
2228 (config.status Invocation): Renamed back from Recreating a
2230 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2231 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2233 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2235 * NEWS: Version 2.61a.
2237 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2238 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2240 * NEWS: Document changes with echo and printf, and the lack
2241 of limits on the total size of multi-line values of substituted
2242 variables, and the AC_FUNC_FSEEKO fix.
2244 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2246 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2247 Writing configure.ac.
2248 (Autoconf Input Layout): Renamed from configure.ac Layout.
2249 (Recreating a Configuration): Renamed from config.status Invocation.
2250 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2251 (acconfig Header): Renamed from acconfig.h.
2252 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2253 (Writing Testsuites): Renamed from Writing testsuite.at.
2254 (Autom4te Cache): Renamed from autom4te.cache.
2256 * BUGS: Remove mention of VPATH problem, since it's now documented
2257 not to be a bug in the Autoconf build procedure itself, but rather
2258 a problem with the proprietary `make' programs.
2260 * doc/autoconf.texi (Build Directories): Add a cross reference
2263 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2264 * doc/standards.texi: Sync from gnulib.
2266 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2267 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2268 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2269 generated automatically.
2271 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2273 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2274 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2275 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2277 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2279 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2280 `CEOF$ac_eof' special marker, the awk script cannot contain a
2281 line matching `^CEOF', so this is not needed any more.
2282 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2283 special marker in the test.
2285 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2287 * tests/tools.at (autom4te preselections): Use `find -newer';
2288 remove one of the sleeps.
2290 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2291 more readable, using ...
2292 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2294 * doc/autoconf.texi (autoheader Invocation): Do not double-
2295 quote the parameter of `AH_BOTTOM' in the example.
2297 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2299 * doc/autoconf.texi (Configuration Headers): Remove the
2300 example with multiple input files.
2301 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2302 multiple input files.
2304 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2307 creating the awk substitution script, handle one input line at a
2308 time, so that the maximum length of a substituted (multi-line)
2309 value is not limited by the size of the sed pattern space.
2310 The trade-off is a slightly repetitive sed script.
2311 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2312 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2313 * tests/torture.at (Substitute a 2000-byte string): Increase the
2314 test with several long lines, they should not be caught by sed
2317 * tests/tools.at (autom4te preselections): New test, to flag
2318 entries missing from autom4te.cfg.
2319 Report by David Byron <dbyron@hheld.com>.
2321 * tests/torture.at (Substitute a 2000-byte string): Actually use
2322 AC_PROG_AWK, so the last change works as intended.
2323 (Substitute and define special characters): Likewise.
2324 (Substitute a newline): Likewise.
2326 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2327 instead of `awk' consistently.
2328 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2329 * tests/torture.at (Torturing config.status): Test both the
2330 result of AC_PROG_AWK and plain awk.
2331 (Substitute a 2000-byte string): Likewise.
2332 (Substitute and define special characters): Likewise.
2333 (Substitute a newline): Likewise.
2335 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2337 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2338 can be assigned to a function pointer. Problem reported by
2339 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2340 part of a patch by Ralf Wildenhues in that same bug report.
2342 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2344 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2345 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2347 2006-12-01 Eric Blake <ebb9@byu.net>
2349 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2350 cross-compiling from cygwin to mingw.
2351 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2352 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2353 to lib/autoconf/c.m4.
2355 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2357 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
2358 string for more reliable failure. Wrap the entire test that
2359 causes the broken Solaris printf to dump core, in a subshell,
2360 so the segmentation fault message is reliably suppressed.
2361 Fix shell expansion errors by using /usr/ucb/echo always;
2362 avoid an error on systems without it by another subshell.
2363 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2364 subshell-$as_echo to `as_echo', for better error message.
2366 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2368 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2369 `BASH_SOURCE' contain a newline, set them to empty, as they may
2372 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2374 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2375 years and is too hard to maintain now. The last straw was
2376 reported by Jerker Baeck in
2377 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2378 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2379 * doc/autoconf.texi (Particular Functions): Move
2380 AC_FUNC_SETVBUF_REVERSED from here...
2381 (Obsolete Macros): ... to here. Say that it does nothing now.
2382 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2383 Turn into (almost) a no-op.
2385 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2387 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2388 These macros are obsolescent and new applications shouldn't need them.
2389 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2390 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
2391 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
2392 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2393 (AC_FUNC_VPRINTF): Likewise.
2394 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
2395 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
2396 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2398 * doc/autoconf.texi (Setting Output Variables): Mention that
2399 @VAR1@VAR2 has unspecified behavior. Problem reported by
2401 * NEWS: Mention this.
2403 * Makefile.am: Put only a single '#' into the copyright notice,
2404 so that it's also present in the output file. Standardize wording
2405 in makefile copyright notices to match GNU coding standards.
2406 * bin/Makefile.am: Likewise.
2407 * doc/Makefile.am: Likewise.
2408 * lib/Makefile.am: Likewise.
2409 * lib/freeze.mk: Likewise.
2410 * lib/autoconf/Makefile.am: Likewise.
2411 * lib/autoscan/Makefile.am: Likewise.
2412 * lib/autotest/Makefile.am: Likewise.
2413 * lib/m4sugar/Makefile.am: Likewise.
2414 * man/Makefile.am: Likewise.
2415 * tests/Makefile.am: Likewise.
2416 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
2419 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2421 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2422 in the sed script that mangles the awk script: delete up to the
2423 first exclamation mark only.
2424 * tests/torture.at (Substitute and define special characters):
2427 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2429 Rewrite config files generation: avoid quadratic growth in
2430 the number of substituted variables by using awk instead of sed
2431 for the bulk of the substitutions.
2432 * NEWS: Mention this.
2433 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2434 forbidden in the output (and thus input) file.
2435 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2436 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2437 generate just one large awk script for substitutions,
2438 eliminating much of the earlier complexity, while adding some
2439 new complexity. Only expand the substitution templates at
2440 configure time, for smaller configure script size. If
2441 _AC_SUBST_FILES are used, test 'awk' for working getline support
2442 at config.status time. If absent, interpolate through the
2443 shell. The awk script was written with much help
2444 from Paolo Bonzini and Paul Eggert.
2445 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2446 (_AC_SED_FRAG_NUM): Likewise.
2447 (_AC_SUBST_CMDS): Renamed from...
2448 (_AC_SED_CMDS): ...this.
2449 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2450 * tests/torture.at (Substitute a 2000-byte string): Also
2451 substitute a line with 1000 words, and a variable with several
2453 (Substitute and define special characters): Test awk special
2454 characters, and put substitution input strings `@foo@' in the
2455 output, to test that no recursion happens; test several other
2456 combinations from Paolo Bonzini.
2458 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2460 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2461 that replaced echo with AS_ECHO where this wasn't necessary.
2462 Problem reportd by Ralf Wildenhues.
2463 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2464 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2465 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2467 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2469 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2471 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2473 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2474 that traditional Awk lacks 3-arg "split". It has it.
2475 Mention that FS must be a single character, and a few other
2476 99-byte limits of traditional Awk.
2477 Mention that if (i in a) doesn't work with traditional Awk.
2479 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2481 * tests/autotest.at (BSx641-newline in command):

2486 Use printf '%s\n' instead of echo, for portability to hosts
2487 where echo interprets backslashes. This will break on hosts
2488 that lack printf, but for now let's assume all such hosts
2489 are dead (if not, we should get reports of test failures).
2491 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2493 'echo' has some portability problems, when given a first argument
2494 with a leading '-', or when given any argument containing '\'.
2495 Avoid using 'echo' in these cases.

2647 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
2650 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2652 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2653 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2654 Imported from a similar patch to gnulib by Bruno Haible.

2680 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.

2685 Single-quote in a test title,
2686 Double-quote in a test title): Don't expect failure anymore.

2699 * tests/torture.at (#define header templates): M4-quote this title in
2700 AT_SETUP call so that no M4 code is commented inadvertently somewhere.

2703 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2705 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
2706 `trap ... 0' inside a function, for AIX sh.
2708 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2710 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2711 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2712 5363) simply issues a warning when dividing by zero at compile
2713 time. Problem reported by Elias Pipping.
2715 2006-10-26 Eric Blake <ebb9@byu.net>
2718 * doc/autoconf.texi (Evaluation Macros): Improve the example to

2747 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2748 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2749 reported by Nelson H. F. Beebe for Coreutils 6.4.
2751 * tests/tools.at (autoconf --trace: user macros): Remove test
2752 for tracing multiline macros, since m4 1.4.7a uses a different
2753 way to number lines. Problem reported by Ralf Wildenhues.

2829 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2831 (Imported from Automake.)
2832 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2833 which incorrectly sets the mode of an existing destination
2834 directory. In some cases the unpatched install-sh could do the
2835 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2836 system. We hope this is rare in practice, but it's clearly worth
2837 fixing. Problem reported by Alex Unleashed in
2838 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2839 Also, don't bother to check for -m bugs unless we're using -m;

2919 Use a better substitute, by inspecting the output of "ls"
2920 rather than just using ":".
2921 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2922 rather than AS_EXECUTABLE_P, since we needn't worry about
2923 non-regular files here.
2925 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,

2953 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2954 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2955 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2957 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2958 with werror_flag and conftest.err and so forth. This is more
2959 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2960 and anyway the user shouldn't normally want to see this gorp logged.
2961 Problem reported by Ralf Wildenhues.
2962 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2963 empty, not 'no', since the rest of the code uses 'test -z'.

2967 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

2971 Problem reported by mwoehlke in
2972 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2974 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2975 than creating a file to use with test -x; this is much faster.

3234 broken lex libraries like native ia64-hp-hpux11.22; see
3235 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

3399 * doc/autoconf.texi (config.status Invocation): Adjust according
3402 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3404 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
3405 --help' should mention that `--version' outputs configuration
3406 settings. Report by Bruno Haible.
3408 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
3410 Fix test suite failures reported by Pierre in
3411 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
3412 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
3413 the compiler created a file "b.out" when it didn't create anything
3415 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
3416 Discard stderr too, when invoking the test script.
3418 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
3420 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
3421 in the restoring of the werror flag.
3423 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
3425 * doc/autoconf.texi (Volatile Objects): Be even a little
3426 less skeptical about "volatile", after discussion with
3427 Bruno Haible on bug-gnulib.
3428 (Limitations of Usual Tools): Warn about sed stripping
3429 leading white space from text. From Bruno Haible.
3431 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3433 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
3434 compiler complains about it, even if things works after the
3435 complaint. Problem reported by Peter O'Gorman.
3437 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
3438 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3439 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3441 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3443 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
3444 after -R regardless of host. Patrick Welche reports that this
3445 fixes things on NetBSD 3.99.
3447 * NEWS: Recommend M4 1.4.5.
3449 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
3450 * tests/tools.at (autom4te cache): Update wording of diagnostic
3453 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3455 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3456 under AC_C_VOLATILE.
3457 (Volatile Objects): Be a little less skeptical about what
3458 "volatile" means. Derived from thoughts by Ben Pfaff in
3459 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3461 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3463 * doc/autoconf.texi: Fix some typos.
3465 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3467 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3468 more globally, since the 2006-06-30 patch didn't suffice. Problem
3469 reported by Keith Marshall. Also, don't bother with builddir2,
3470 since it shouldn't be needed any more.
3472 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3474 * doc/autoconf.texi (Generic compiler characteristics):
3475 Document AC_COMPUTE_INT. Fix wrong statements on Default
3476 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
3478 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
3479 (_AC_COMPUTE_INT): Add obsoletion warnings.
3480 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
3483 * NEWS: Document change.
3485 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
3487 * doc/autoconf.texi (Volatile Objects): New section.
3489 * NEWS: Document previous change.
3491 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3493 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3494 Require that long long int be at least 64 bits wide. C99 requires
3495 this and enough programs depend on it so we should check for it.
3496 Bruno Haible reports in
3497 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3498 that long long int is 32 bits wide with some nonstandard compilers.
3499 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3501 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3503 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3504 to a nonexistent file, so that we don't have to worry about
3505 a local site configuration that doesn't use /usr/local.
3506 Problem reported by Keith Marshall in
3507 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3509 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3511 * doc/autoconf.texi: Be more consistent about using @acronym with
3512 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3513 quite right (it talked about "OSF/Tru64", even though the
3514 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3515 and it even mentioned "OSF 4"!) and at this point there's little
3516 reason to talk about OSF any more, since it died in 1994.
3517 (Specific Compiler Characteristics): Simplify example of
3518 negative-size array.
3519 (File Descriptors): Reorder to make the text flow better.
3520 Remove joke about "appreciate the various levels"; I didn't get it.
3521 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3522 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3523 (File Descriptors, Limitations of Usual Tools):
3524 Tone down the advice against renaming or removing open files.
3525 (Limitations of Usual Tools): Add a new section, on 'rm'.
3527 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3529 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3530 -lXt in LIBS, idea from Karsten Hopp; this was due since
3533 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3534 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3535 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3536 (which belong to Xt, not X itself). See Debian bug 327655.
3538 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3540 * configure.ac (AC_INIT): Bump to 2.60a.
3543 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3547 * configure.ac, NEWS: Update.
3549 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3551 * config/texinfo.tex: Sync from upstream.
3553 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3554 quadrigraph correctly in traces.
3556 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3559 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3560 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3562 * doc/autoconf.texi (Changed Directory Variables): New node,
3563 to document the whole `datarootdir' business a bit better.
3565 * tests/torture.at (datarootdir workaround): Extend test.
3566 Prompted by report by Alexandre Julliard.
3568 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3570 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3571 when using default mode of IBM C 6 for AIX. Problem and two-line
3572 fix reported by Larry Jones.
3574 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3576 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3577 about literal '${datarootdir}' if a definition is found in the
3580 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3582 * NEWS: Use "M4" rather than "m4" when appropriate.
3583 Problem reported by Eric Blake.
3584 * doc/autoconf.texi: Likewise.
3585 Use @acronym around BSD, GCC, and GNU when appropriate.
3586 (Why GNU M4): Renamed from "Why GNU m4".
3587 (Redefined M4 Macros): Mention that Posix
3588 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3589 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3592 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3594 * bin/autom4te.in (handle_output): Do not forbid the empty
3596 * tests/tools.at (autoconf: the empty token): New test.
3598 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3600 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3601 calls, so that we do not care whether they are LIFO or FIFO;
3602 in the m4_wrap, do not check which diversion is the topmost
3603 one, just check that the stack is balanced at the end.
3604 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3605 base diversion forever--pop the previous diversion before
3606 opening the new one; consequently, remove the m4_wrap call.
3607 * lib/autotest/general.m4 (AT_INIT): Likewise.
3608 * tests/m4sugar.at: Do not use
3609 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3611 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3612 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3614 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3615 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3616 Rework example of m4wrap token-pasting trouble so that it doesn't
3617 care whether it's LIFO or FIFO.
3618 Fix some "contrary to"s that are awkward in English.
3620 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3622 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3623 to `yes' instead of `int$1_t' if the type is found, for more
3624 consistent configure output (where $1 is the number of bits).
3625 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3626 Suggested by Bruno Haible.
3628 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3629 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3630 with system headers. Report by Bruno Haible.
3632 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3634 * config/config.guess, config/config.sub: Sync from upstream.
3636 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3637 in order to avoid picking up an older installed frozen m4sh.m4f.
3638 Besides an outdated shell startup, this could have been created
3639 by an earlier M4 version with incompatible frozen file format.
3641 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3643 * README: Recommend m4 1.4.4 instead of 1.4.3..
3644 * doc/autoconf.texi: Likewise.
3645 (Special Chars in Names): Say that $(.FOO) is portable, as
3646 suggested by Stepan Kasal.
3647 (Installation Directory Variables, Build Directories):
3648 (Automatic Remaking, Subdirectories, Fortran Compiler):
3649 (Making testsuite Scripts, Defining Directories):
3650 Quote variable usages better.
3651 (Making testsuite Scripts): Add clean-local rule to makefile
3652 snippet, by Eric Blake.
3653 (Installation Directory Variables): Fix table item font.
3654 Reword slightly to clarify. Generalize advice about
3655 not using special characters to include all file-related
3656 vars, not just VPATH.
3657 (Special Chars in Variables): Warn about special characters in
3659 (Assignments): Clarify default-value example as suggested by
3661 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3662 (Special Shell Variables): Note leading ./ or ../, as suggested
3664 (Limitations of Builtins): Under cd, warn about CDPATH.
3665 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3668 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3670 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3671 `@var', for texi2html.
3672 (Systemology): Some more word wrapping, for DVI output.
3673 (autom4te Invocation): The short option for `--melt' is `-M',
3676 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3678 * doc/autoconf.texi: More formatting and English tweaks,
3679 many suggested by Ralf Wildenhues.
3680 Reword to avoid "@code{...}'s" and the like, since it's ugly
3681 with Emacs info mode. discontents -> woes.
3682 Put a few "will"s back. time stamp -> timestamp.
3683 side-effect -> side effect.
3685 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3687 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3688 Warn about $@ not persisting. Problem reported by Julien Danjou in
3689 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3690 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3691 Mention other special chars, too.
3693 2006-06-14 Eric Blake <ebb9@byu.net>
3695 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3697 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3699 * doc/autoconf.texi: Some systematic minor improvements, as
3700 follows. Use "makefile" when talking about makefiles
3701 generally (which might be named "makefile" or "Makefile" or even
3702 "foo.mk"), "Makefile" when talking about a specific makefile
3703 called "Makefile". This unclutters the text from weird quotes
3704 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3705 values" rather than "@var{foo}s" and similar constructs containing
3706 "}s". Use "Make rules" rather than "Makefile rules". Minor
3707 English-language improvements. Change the prefix "sub-" to "sub"
3709 Put blank lines around examples more consistently.
3710 Avoid "rather" and "very" as intensifiers.
3711 Avoid "will" as an auxiliary.
3712 (Limitations of Make): Split this node into....
3713 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3714 (Leading _ in Macro Names, Backslash-Newline-Newline):
3715 (Backslash-Newline Comments, Long Lines in Makefiles):
3716 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3717 (obj/ and Make, make -k Status, VPATH and Make):
3718 (VPATH and Double-colon, $< in Explicit Rules):
3719 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3720 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3721 New nodes, resulting from splitup of Limitations of Make.
3722 All cross-references changed. Raise the top node from
3723 a section to a chapter, and all subnodes accordingly.
3724 Redo the introductory wording to match the new organization.
3725 (Installation Directory Variables): Use an example that is
3726 closer to what Autoconf actually does. Mention that VPATH's
3727 value should not contain metacharacters or white space.
3728 (Fortran Compiler): Fix a VPATH bug in an example.
3729 (Leading _ in Macro Names): Mention that this problem is no longer
3730 of practical concern.
3731 (VPATH and Make): Reword the advice to make it clearer
3732 that Autoconf and Automake support VPATH in non-GNU make, but
3733 many packages have bugs in this area.
3734 ($< in Explicit Rules): Refer to Build Directories rather
3735 than using a (non-VPATH-safe) example.
3736 (Automatic Rule Rewriting): Mention the sort of disaster that
3737 can ensue with Solaris-style rule rewriting with VPATH.
3739 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3741 * doc/install.texi (Compilers and Options): Weaken the
3742 suggestion to use GNU make for VPATH builds.
3744 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3745 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3747 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3748 in regular expression.
3750 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3752 * doc/autoconf.texi (Installation Directory Variables):
3753 Drop extra @samp from `@table @samp' item.
3754 (Limitations of Usual Tools): Comment fix.
3755 Do not nest @samp just to point to other table items.
3756 (Writing testsuite.at) <AT_CHECK>: The second argument to
3757 `@dvar' is already @samp'ed.
3758 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3759 do not use @var in the second argument.
3761 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3763 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3764 $as_shell.exe too. Problem reported by Andreas Buening in
3765 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3767 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3769 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3770 `unused variable' compiler warning, for `-Wall -Werror'.
3771 Reported by Jaap Haitsma in
3772 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3774 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3776 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3777 case the compiler dumps core. Problem reported for
3778 OpenServer 5.0.7 by Tim Rice in
3779 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3780 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3783 2006-06-06 Tim Rice <tim@multitalents.net>.
3785 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3786 "ERROR" only shows up in "make check" output if there is an

3810 * config/texinfo.tex: Sync from upstream.
3812 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3813 seen, invoke libtoolize with `--ltdl' argument.
3814 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3816 Suggested by Eric Blake.
3818 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

3863 Prefer "current" to "modern" to describe
3864 currently-used (albeit perhaps old-fashioned) hosts.
3865 Mention which ancient features no longer need to be worried about.
3866 setgid -> set-group-ID
3867 setuid -> set-user-ID (these are the Posix terms)

3879 (Installation Directory Variables): shall -> should
3880 (File Descriptors): Mention that 0, 1, 2 might get reopened.
3881 Mention that it's now safe to use 3 and 4.
3882 (Limitations of Usual Tools): cp -r is now specified by Posix.
3883 Omit longwinded and obsolescent discussion of cp -f.
3884 Modernize discussion of expr, ls.
3885 (Limitations of Make): Modernize discussion of VPATH builds.
3886 Mention $? as a workaround in some cases.
3887 * doc/install.texi (Basic Installation):
3888 Mention "./configure; make; make install" first. Be more
3889 specific about why this file is generic. Remove unnecessary
3890 parens. Remove misleading "only". Remove obsolete advice
3891 about csh. Don't say "configure" takes awhile; say it
3892 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3893 and CC=c99 rather than CC=c89, as these are blessed by current
3894 Posix. Recommend GNU make if doing a VPATH build.
3896 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3898 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3899 examples involving shell prompts.
3901 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3902 and Paul Eggert <eggert@cs.ucla.edu>
3904 * doc/autoconf.texi (Here-Documents): Add details about the
3905 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3906 use "here-documents" instead of "here documents".
3908 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3910 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3912 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3914 * doc/autoconf.texi (File System Conventions): Warn about ":"
3915 anywhere in directory names.
3917 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3919 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3920 about quoting the case statement, just in case.
3921 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3922 was fixed in ksh93g; reported by Ralf Wildenhues.
3924 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3926 * doc/autoconf.texi (System Services): Do not document
3927 overriding EXEEXT via ac_cv_exeext=ext.
3928 (Particular Programs) <AC_PROG_MKDIR_P>:
3929 Document that ${MKDIR_P} understands --.
3930 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3933 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3935 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3936 argument with leading hyphen. Problem reported by Paul Eggert.
3938 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3940 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3941 about quoting ac_try: quote all of it, if any of it seems suspicious.
3942 This means we don't have to worry about ${ or sed any more.
3943 Also, double-quote the case statement, to work around misuses via
3944 underquoting as reported by Ralf Wildenhues in
3945 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3946 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3947 undocumented and dangerous macro.
3948 Problem reported by Ralf Wildenhues in
3949 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3951 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3953 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3954 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3955 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3957 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3959 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3960 since evidently some packages rely on the old, broken behavior.
3961 Problem reported by Ralf Wildenhues in
3962 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3963 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3964 pre-2006-05-26 definitions, but leave in the comments that
3965 these macros are dangerous and should not be used.
3966 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3967 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3968 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3969 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3970 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3972 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3974 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3975 the use of 'tr', since this is our only use of 'tr'.
3977 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3978 and Paul Eggert <eggert@cs.ucla.edu>
3980 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3981 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3983 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3985 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3986 the output file in the `${datarootdir}' test.
3988 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3989 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3991 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3992 mention of `datarootdir' in the input file(s), but literal
3993 `${datarootdir}' in the output file, and we haven't warned yet,
3994 then warn as well: the user may have (erroneously) used
3995 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3996 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3997 * tests/torture.at (datarootdir workaround): Extend this test.
4000 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4001 and Paul Eggert <eggert@cs.ucla.edu>
4003 * doc/autoconf.texi (autoheader Invocation): The first argument to
4004 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
4005 alternatives and clear up the language a bit.
4007 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4009 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4010 ac_config_guess, ac_config_sub, ac_configure.
4011 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4012 Fix typo that prevented an unnecessary space from being removed.
4013 Problems reported by Ralf Wildenhues in:
4014 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4016 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4018 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4019 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4020 Don't use the term "thread-safe" to talk about mkdir race
4021 conditions, since the problem is more a process than a thread
4022 issue. Problem reported by Stepan Kasal in:
4023 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4024 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4025 the test for 'install' more closely. Look at MKDIR_P first.
4026 Look in the PATH, and at /opt/sfw/bin.
4027 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4028 Don't bother to try mkdir -p, since we already check mkdir --version;
4029 just look at the version number. (There's no easy way to check
4030 for race-free implementations.)
4031 * tests/tools.at (autoconf: subdirectories): Adjust to above
4032 changes, since MKDIR_P now might end in "/mkdir -p".
4034 * doc/autoconf.texi (autoheader Invocation): Mention that the
4035 first arg of AC_DEFINE_UNQUOTED must be a literal.
4036 Problem reported by Ben Pfaff in
4037 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4039 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4040 * doc/autoconf.texi (Special Chars in Variables): New section.
4041 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4042 (Installation Directory Variables): Quote $(datadir) better.
4043 (Limitations of Builtins): Describe some of eval's trickiness.
4045 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4046 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4047 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4048 in front of every arg, not just trailing args. Quote apostrophes.
4049 (_AC_EVAL_ECHO): New macro.
4050 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4051 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4053 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4054 exposed by quoting of eval argument. Put the command on line line
4056 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4057 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4058 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4059 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4060 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4061 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4062 Use eval more safely.
4063 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4064 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4066 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4067 lines, exposed by quoting of eval argument.
4069 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4070 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4072 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4073 initialization of `ac_cv_exeext', do not override it if it was
4074 already set, unless it was set to `no', for compatibility with
4075 Autoconf-2.13, and comment this.
4076 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4077 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4078 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4079 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4080 Document that this test may be overridden by setting
4083 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4085 Revert these two patches:
4087 2006-04-06 Eric Blake <ebb9@byu.net>
4088 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4089 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4092 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4093 Clean up _AC_COMPILER_EXEEXT* macros.
4094 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4095 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4096 ac_file to the name of the default output file and call
4097 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4098 initial `rm' of the candidate files...
4099 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4100 the same list in subsequent `rm' calls, and for the temporary
4101 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4102 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4103 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4104 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4105 no longer needed) by libtool. Make it a cache check.
4106 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4107 copied here by mistake.
4108 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4109 _AC_COMPILER_EXEEXT.
4110 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4111 _AC_COMPILER_OBJEXT directly.
4112 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4114 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4116 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4117 Fix description of how the buggy `sed' works.
4119 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4123 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4124 ENOLCK. Only mention `make -j' when applicable. Only raise
4125 fatal errors when `make -j' is involved. Improve error message.
4127 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4129 * doc/autoconf.texi (Here-Documents): We now know more about
4130 the variable expansion in here documents bug.
4131 Thanks to Tim Rice and Stepan Kasal.
4133 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4134 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4136 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4138 * tests/autotest.at (Multiline command from M4 expansion):
4139 No failure to be expected if the shell quotes newlines in
4140 commands in the `set -x' output. Report by Tim Rice.
4143 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4145 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4146 expansion in the here-documents used by config.status, as that
4147 runs afoul of the Korn shell version M-12/28/93d bug described in
4148 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4149 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4150 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4152 2006-05-23 Jim Meyering <jim@meyering.net>
4154 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4155 Fix typo introduced with 2006-04-02 change. It reversed the sense
4158 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4160 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4161 ac_dB slightly, to save bytes in the script.
4162 Max out at 50 lines, rather than 96; this is more likely
4163 (though not guaranteed) to avoid obscure 'sed' failures.
4165 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4167 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4168 `tr -d -' as bad option argument. Work around this by deleting
4169 an unrelated character.
4170 Report by Tim Rice <tim@multitalents.net>.
4172 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4173 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4174 Stepan Kasal <kasal@ucw.cz>
4176 * doc/autoconf.texi (Particular Programs): Do not promise that
4177 we always prefer the GNU version of the program, and that we
4178 search according to PATH; both rules can have exceptions.
4179 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4180 AC_PROG_SED. Move descriptions of limitations
4181 to the Limitations of Usual Tools section.
4182 (Limitations of Usual Tools) <sed>: Mention script length
4183 limitations with Solaris /usr/ucb/sed.
4184 <grep>: Fix wording for empty alternative. Mention that -c and
4185 -l should not be combined, and that -E and -F should not be
4188 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4189 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4191 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4192 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4194 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4196 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4197 AC_DEFINE is now passed to m4_pattern_allow.
4198 * NEWS: Mention that; likewise for AC_SUBST.
4199 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4200 the parameter to m4_pattern_allow.
4201 * tests/tools.at: Add a check for that.
4203 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4205 * lib/autoconf/status.m4: Fix typos.
4207 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4209 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4210 only the files that this macro generates.
4212 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4214 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4215 the HP-UX sed limitation of 99 commands, labels do not count.
4216 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4218 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4220 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4222 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4223 Import the following fix from coreutils:
4225 2006-01-13 Jim Meyering <jim@meyering.net>
4227 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4228 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4229 not double-quote uses of that variable, to accommodate the rare
4230 case in which getmntent is available in none of the libraries
4231 checked. This happens at least on FreeBSD 5.0.
4233 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4235 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4236 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4237 some other programs unwisely rely on these undocumented vars.
4238 But put in warning comments about them.
4239 Problem reported by Ralf Wildenhues in
4240 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4241 * NEWS: Document that these variables are intended to go away.
4243 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4245 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4246 and set the language to C++ (analogous to the equivalent Fortran
4249 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4250 * doc/autoconf.texi (C++ Compiler): Document it.
4251 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4254 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4256 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4257 that caused config.status to generate 100-command sed scripts; the
4258 portable limit is 99.
4260 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4262 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4263 variable `ac_d' instead of `d' to avoid infringing namespace.
4264 Report by Ralf Menzel.
4266 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4268 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4269 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4270 * tests/tools.at (autoconf: subdirectories): New test, taken from
4271 the corresponding problem report by Ralf Wildenhues in:
4272 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4274 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4275 Quote some uses of shell variables if they might suffer unexpected
4276 globbing. This doesn't fix all instances of quoting problems that
4277 I found, just the easy ones that look safe.
4278 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4279 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4280 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4281 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4282 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
4283 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4284 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
4286 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.

4289 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4291 * bin/autoreconf.in ($help): Reword according to the manual.
4292 Suggested by Olly Betts.
4294 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4295 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4297 * bin/autoreconf.in: Pass the directory argument to
4298 `require_configure_ac'. Fix comment.
4299 * tests/torture.at (Configuring subdirectories): Expose this.
4300 Reported by Olly Betts.
4302 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4304 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4305 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4306 Automake as follows:
4308 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4309 `$configure_in' instead of `configure.in', to preserve
4310 directory component.
4312 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4314 * config/config.guess, config/config.sub, config/texinfo.tex,
4315 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4317 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4319 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4320 test for C99 conformance; (bool) 0.5 is an integer constant
4321 expression, but (bool) -0.5 is not. Problem reported by Fedor
4322 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4324 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4326 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4327 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4328 Warn about obsolete install-sh files. Remove stray sentence
4329 fragment and fix cross reference.
4330 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4331 install -d; this undoes the 2006-05-10 change.
4332 (MKDIR_P): Mark with AN_MAKEVAR.
4333 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4334 that we don't require $INSTALL to be thread-safe. Move comments
4335 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4336 of AC_PROG_INSTALL. Output a message saying that we're checking
4337 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4338 MKDIR_P instead of AC_SUBST.
4339 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4340 Special magic for MKDIR_P, too.
4341 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4343 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4345 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4347 Sync from Automake, as follows:
4349 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4350 * config/install-sh: Initialize IFS, so field splitting isn't
4352 * config/mkinstalldirs: Likewise.
4353 * config/missing: Remove superfluous quotes. Replace all uses of
4354 `[' by `test', for consistency, and for..
4355 * config/missing (sed_minuso, sed_output): New variables.
4356 (autom4te, help2man, makeinfo): Use them. Unifies detection of
4357 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
4358 Fixes `missing' to detect `--output' for help2man. Fixes
4359 PR automake/483. Report by Dennis J. Linse.
4360 (autom4te): Document in `missing --help'.
4362 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4364 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4365 * config/install-sh: Don't use 'path' to talk about file names,
4366 as per GNU coding standards. Close a race condition reported by Ralf
4367 Wildenhues and Stepan Kasal. There is still a race condition
4368 on hosts that predate Posix 1003.1-1992, but we can't help this.
4369 Don't mishandle weird characters like space on pre-Posix hosts.
4370 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4371 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4372 AC_PROG_MKDIR_P from AS_MKDIR_P.
4373 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4374 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4375 earlier editions are not (including Automake 1.8.3).
4376 Do not suggest mkinstalldirs for thread-safety.
4377 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4378 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4379 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4380 presence of special characters and race conditions.
4381 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4382 in Autoconf's name space.
4384 2006-05-10 Bruno Haible <bruno@clisp.org>
4385 and Paul Eggert <eggert@cs.ucla.edu>
4387 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4388 from Automake with minor changes.
4389 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4391 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4393 * config/install-sh: Update to Automake CVS version, as follows:
4394 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4395 * lib/install-sh: Simplify the expr implementation of dirname.
4396 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4397 * lib/install-sh: Handle --, and diagnose unknown options.
4399 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4401 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4402 `./autom4te' to create `./testsuite', since the `all' target
4403 will ensure its presence, but `installcheck' should not create
4404 the uninstalled wrappers.
4406 * tests/torture.at (Unusual Automake input files): Skip if we
4407 detect automake < 1.8.
4409 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4411 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4412 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4413 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4416 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4418 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4419 munge (multiple) white space and other oddities.
4420 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4421 single quotes in variable assignment.
4422 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4423 and similar failures by adding multiple spaces, tabs, and other
4425 Report and different test suggested by Francesco Romani
4426 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4428 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4429 single quotes, we only need to search for single quotes; this
4430 both simplifies the search pattern, and makes us less
4431 susceptible to `echo' variations for arguments not containing
4433 (_AC_ARG_VAR_VALIDATE): Likewise.
4435 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4437 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4438 `$*' and IFS concatenation issue with traditional shells and
4439 bash-2.04. Report by Seanster@Seanster.com.
4441 2006-05-03 Bruno Haible <bruno@clisp.org>
4443 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4444 precisely which Mac OS X versions have the od problem.
4446 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4448 * doc/autoconf.texi: Use @option systematically.
4450 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4451 and Bruno Haible <bruno@clisp.org>
4453 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4455 (Integer Overflow): Mention the special case of integer division
4458 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4460 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4461 traditional shells like the Solaris one that do not use the
4462 first IFS character for assembling `$*'.
4463 Prompted by a related report from autoconf_bug@nro.ca.
4465 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4466 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4468 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4469 Mention more problems with the -e option.
4471 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4474 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4476 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4477 in URLs to improve DVI formatted output (requires texinfo 4.6).
4478 (System Services, Systemology, Shellology): Likewise.
4479 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4482 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4484 (Runtime): Fix macro argument names to match description:
4485 `action-if-found' -> `action-if-true' and similarly.
4486 (Obsolete Macros): Likewise.
4487 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4488 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4489 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4491 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4493 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4496 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
4499 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4501 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
4502 /bin/sh set unsorted output.
4503 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

4508 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
4509 (Integer Overflow, Null Pointers, Buffer Overruns):
4510 (Floating Point Portability, Exiting Portably): New sections.
4511 (Writing Test Programs): Fix some langauge. Recommend exiting
4512 with status 1, not merely nonzero. Clarify exit declaration.
4513 (Run Time): Move C exit status stuff to new Exiting Portably section.
4514 (Systemology): Mention Posix and levenez. Update v7 reference.
4515 (Portable Shell): Mention the Posix shell.
4517 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4519 * bin/autoconf.as (me): Replace by as_me.
4521 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4523 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4524 since as_me isn't set yet.
4526 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4528 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4529 a few minor bugs in this area.
4531 * doc/autoconf.texi (Programming in M4sh): Comment out the
4532 documentation of AS_BASENAME, for now.
4533 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4534 (Limitations of Builtins) <basename>: Do not refer to
4536 * bin/autoconf.as (me): Don't use AS_BASENAME.
4537 (dir): Remove the unused variable.
4538 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
4539 AS_DETECT_REQUIRED. All uses changed.
4540 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
4542 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
4543 (AS_BASENAME): Use "basename --" to protect against leading "-".
4544 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
4545 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
4546 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
4547 (_AS_DIRNAME_PREPARE): Likewise.
4548 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
4549 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
4550 (AS_DIRNAME): Use "dirname --".
4552 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4554 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4555 of "run time" and "run-time" changed to "runtime", for consistency.
4556 * lib/autoconf/fortran.m4: Likewise (in comment).
4557 * lib/autoconf/functions.m4: Likewise.
4558 * lib/autoconf/general.m4: Likewise.
4559 * lib/autoconf/headers.m4: Likewise.
4561 * doc/autoconf.texi (Run Time): Document the exit status situation
4562 with more accuracy and detail.
4564 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4566 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4567 Archive is not officially `GNU' any more. Update URL.
4568 (Defining Directories): Likewise
4569 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4571 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4573 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4574 newline from the `trap' code to finish `config.log'; the NetBSD
4575 /bin/sh resets the exit status after an empty command, as
4576 documented in doc/autoconf.texi.
4577 Reported by Dalibor Topic <robilad@kaffe.org>.
4579 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4581 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4582 Suggested by Bruno Haible.
4584 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4586 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4587 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4588 Instead, just list the shells that we know work.
4589 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4590 changed. Be more cautious about the _cv_ variable.
4591 * tests/tools.at (Syntax of the shell scripts): Check the
4592 _cv_ variable once, at first, to avoid an internal autoconf error
4593 when sh -n does not work.
4595 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4597 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4599 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4601 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4602 use ">&-" since we're only 99.999% sure that this is portable,
4603 and since the MinGW bug is fixed in a different way.
4604 * lib/autotest/general.m4 (AT_INIT): Likewise.
4606 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4608 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4609 before opening config.log, to avoid hitting a bug on MinGW.
4611 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4613 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4614 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4615 This works around a MinGW bug reported by Eric Paire.
4616 Make sure that all writes to the log file append to it,
4617 rather than possibly losing data.
4618 * lib/autotest/general.m4 (AT_INIT): Likewise.
4620 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4622 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4625 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4629 * configure.ac (AC_INIT): Bump to 2.59d.
4631 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4635 * Makefile.maint (news-date-check): Do not require a leading `*'
4636 before the release date in NEWS.
4638 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4639 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4641 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4642 the instantiated file do not contain the string 'datarootdir'
4643 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4644 @mandir@, replace the reference '${datarootdir}' by the value.
4645 * tests/torture.at (datarootdir workaround): New test.
4646 * NEWS: Advertise this temporary fixup.
4647 Based on a patch by Bruno Haible, reported and analyzed by
4648 Paul Eggert and Noah Misch.
4650 2006-04-12 Eric Blake <ebb9@byu.net>
4652 * tests/autotest.at (Debugging a failed test): Fix comment.
4654 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4656 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4657 all the changes since 2006-04-07.
4659 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4661 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4662 succeeded, but `ln -s file dir' failed, take care to remove the
4663 leftover target before the next test, to prevent its spurious
4664 failure; also make sure `ln file dir' works before selecting it.
4665 Thanks to Keith Marshall for pointing this out.
4668 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4669 assignments in `at_debug_args', so that we put them correctly
4670 in the `run' script.
4671 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4672 Reported by Eric Blake.
4674 2006-04-11 Eric Blake <ebb9@byu.net>
4676 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4677 top-level tests after micro-suite has been run. Used in...
4678 (Debugging a successful test, Debugging script and environment),
4679 (Debugging a failed test): ...these new tests. The first of these
4681 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4682 macro, split out from...
4683 (AT_INIT): ...here, so that using -d also generates a run script.
4684 Document that -d inhibits top-level logging.
4685 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4686 inhibits top-level logging; debug scripts are created.
4688 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4690 * tests/autotest.at (Empty test, Empty check): New test to check it.
4692 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4695 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4697 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4698 the files if a problem appears. Make the empty *.at files
4699 read-only, too. Proposed by Ralf Wildenhues.
4701 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4703 * config/Makefile.am: Add comment to force updated Makefile.in.
4705 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4706 space only patch to this file, this patch causes the Makefile.in
4707 files that include freeze.mk to be updated, and thus have a
4708 newer time stamp again, which in turn makes a pristine CVS
4709 checkout have correct time stamps.
4711 * Makefile.maint (cvs-sv): New macro, to be used..
4712 (config.guess-url_prefix, config.sub-url_prefix)
4713 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4714 point to CVS text checkout of Gnulib files.
4715 (copyright-check): Bump current year.
4716 (announcement): Do not hard-wire `./announce-gen'.
4717 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4719 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4721 (wget_files): Update config.guess, config.sub, texinfo.tex by
4722 `wget-update', now that their URLs work again.
4724 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4726 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4727 Problem noted by Paul D. Smith.
4729 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4731 * doc/autoconf.texi: Remove unused words from word list.
4732 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4733 .x-sc_trailing_space: New files.
4735 * doc/standards.texi: Sync from gnulib.
4737 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4738 `LIBOBJDIR' as experimental.
4740 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4741 with a target directory; it's internally implemented as `cp'
4742 anyway, but since Autoconf advertises the possibility to use
4743 a target directory when LN_S is `ln -s', we need to find out.
4744 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4745 analyzed by Keith Marshall <keith.marshall@total.com>.
4749 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4751 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4752 confdefs.h as-is. In general, if it has backslash-newline or the
4753 like, then it doesn't work either to sort or to remove empty
4756 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4758 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4760 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4762 * lib/autom4te.in (Automake-preselections): Preselect
4765 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4767 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4768 apostrophe within a single-quoted string, as this is the usual
4769 tradition and is easier to read than '"'"'. Don't rely on the
4770 shell treating "$/" like '$/'. Use a more-consistent indenting
4773 2006-04-09 Eric Blake <ebb9@byu.net>
4775 * tests/autotest.at (Backquote command substitution),
4776 (Multiline backquote command substitution): Remove mistaken
4777 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4779 (Parenthetical command substitution, Multiline parenthetical
4780 command substitution): here.
4782 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4784 Import macros from gnulib (often changing their name).
4786 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
4787 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

4860 _AS_DETECT_BETTER_SHELL:
4862 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

4891 AS_MKDIR_P exits the script on failure.
4892 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4894 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4913 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4915 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4916 whether `set' quotes correctly: redirect stderr of the tested
4917 `set', and use a subshell, for Ultrix; use `sed' instead of
4918 `grep' for zsh `set' which may write binary output; match only
4919 at the beginning of a line, to avoid false positives.
4920 In order to avoid false positives by unrelated variables with
4921 multiline content, put the dump algorithm in a subshell and
4922 unset all variables containing newlines (except some which are
4923 special to the shell). Warn about cache variables that are

4969 ac_config_<foo>s again, sometimes normalized, sometimes not.
4970 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4971 (AC_CONFIG_COMMANDS): Do not do so here.
4972 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4973 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4974 2005-07-25 rewrite. Noticed by Noah Misch.
4976 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4977 _AC_PRESERVE_HELP_ORDER, ...

4984 for --help from Cygnus `configure.'
4986 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5038 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5039 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

5043 (exclude_list): Exclude empty macros.
5044 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

5127 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5128 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5129 ac_file to the name of the default output file and call
5130 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5131 initial `rm' of the candidate files...
5132 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5133 the same list in subsequent `rm' calls, and for the temporary

5138 no longer needed) by libtool. Make it a cache check.

5215 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5217 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
5218 switch all of them on and of when necessary. Fixes the bug when

5916 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
5917 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5918 by the function rather than ignoring it.
5919 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5920 comparing its address. Intel's interprocedural optimization was
5921 outsmarting the old heuristic. Problem reported by

5939 Stepan Kasal <kasal@ucw.cz>
5941 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5942 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5943 make its content writable before removing it. Remove an errorneous
5944 comment from the end, where the logs of the failed tests are copied
5945 to the main log file.
5947 2005-09-27 Stepan Kasal <kasal@ucw.cz>
5949 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

5954 problems if the testsuite were running too fast.
5956 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5958 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5959 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5960 (which belong to Xt, not X itself). See Debian bug 327655.
5961 * NEWS: Mention this.
5963 2005-09-07 Stepan Kasal <kasal@ucw.cz>

5970 suggested by Ben Elliston. Handle weird characters correctly.
5972 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5974 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5975 calls, so that the final expansion of this macro is shorter.
5976 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5977 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5978 the cleanup there. Use AS_VAR_* macros, to be more general.
5979 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5981 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5983 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

6001 2005-08-26 Stepan Kasal <kasal@ucw.cz>
6003 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
6004 in the example. Reported by Bruno Haible.
6005 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
6006 "if $undefined_var;" succeeds with my shell.
6008 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6009 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6010 but change the m4_divert_text to m4_divert_once.
6012 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6014 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6015 Work around bug in Solaris /usr/xpg4/bin/awk.
6016 The bug is present in at least Solaris 8 through 10.
6018 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6020 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6021 some evil values and relying on the fact that $* concatenates the
6022 parameters by the first character from IFS.

6028 first header appears, define AH_HEADER.
6029 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6030 Update limitations about when to call AC_CONFIG_HEADERS.
6031 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6032 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6033 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6034 ``Configuration Actions''; fix their index entries.
6036 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6037 options correctly. Process N-M as M-N if M is smaller than N.
6038 Process ranges correctly so that N-N will run only N.
6039 Sort and uniquify the tests that will be run. If there is more
6040 than one test, reinsert the banners for the tests.

6043 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6045 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6046 before passing the macro name to AH_TEMPLATE.
6048 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
6049 now opens log after option processing; in particular, --version
6050 and --help do not touch config.log.

6067 Prepend to LIBS, not append, in examples.
6069 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6071 When building in place, set srcdir="."; suggested by Tim Van Holder.
6073 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6074 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6075 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6076 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6077 does not mean "no --srcdir option".
6079 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6081 * tests/autoscan.at (autoscan): New file.
6082 * tests/suite.at: Use it.

6090 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6091 add "2>&1"; gzip 1.2.4 prints help on stderr.
6093 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6095 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6096 was pushdef'ed twice while popped only once. Push it only once.
6097 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
6099 2005-07-26 Stepan Kasal <kasal@ucw.cz>
6101 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

6108 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6109 "<tab>" in comment, so that the point is understandable.
6111 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6113 Rewrite substantial part of lib/autoconf/status.m4.
6114 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6115 and CONFIG_COMMANDS are not processed in four separate loops.
6116 Instead, there is one main loop. This alows that the common code
6117 is expanded only once, thus config.status (and configure) is smaller.
6119 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6120 the AC_LIST_FILES and cousins macros are no longer used.
6122 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6123 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6124 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6125 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6126 contain the initialization, nor the for loop, nor the associated
6127 commands; all these go to ...
6128 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6129 _AC_OUTPUT_CONFIG_STATUS.
6130 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6131 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6132 (_AC_OUTPUT_FILE): The creation of the sed script ...
6133 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6134 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6135 _AC_OUTPUT_MAIN_LOOP.
6136 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6137 _AC_CONFIG_COMMANDS): Use ...
6138 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6139 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6140 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6141 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6142 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6143 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6145 (_AC_CONFIG_UNIQUE): Update.
6146 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6147 Replaced by this ...
6148 (_AC_LIST_TAGS): ... new common macro.
6149 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6150 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6151 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6152 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6153 this didn't belong to the `config commands' section.
6154 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6155 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6156 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6157 to the `config commands' section either.
6158 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6159 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6161 ... and many changes to the comments nearby.
6163 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6164 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6165 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6166 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6167 (#define header templates): The comment at the top of the generated
6168 header now includes the name(s) of the source file(s).
6170 Several unrelated small changes:
6172 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6173 parameter to AC_DIAGNOSE.
6174 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6175 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages

6276 configure_input, top_builddir, srcdir, etc.
6277 * lib/autotest/general.m4 (AT_INIT): Likewise, for

6288 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

6349 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

6370 variable into diagnostic. Make the diagnostic an error, not a warning,
6371 because we really don't support spaces and suchlike in dir names.
6372 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6373 Don't worry about backslashes in srcdir; it can't happen now.

6417 * doc/autoconf.texi:
6418 Don't mention Solaris versions so much, if a
6419 problem is common to all extant versions of Solaris. Say "SunOS
6420 4" instead of "SunOS" for SunOS 4.
6421 (awk): Mention more of the limitations of traditional Awk.

6465 -u, since it outputs chatter if the input files are the same.
6466 Problem reported by Ralf Menzel.
6468 2005-06-08 Derek Price <derek@ximbiot.com>
6470 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6471 renaming them since they are about to be redefined anyhow.

6512 m4_cdr of one-member list was [[]] (one-member list containing an
6513 empty string) instead of [] (an empty list. Callers were skewed to
6514 match this misbehaviour. As a consequence of this:
6515 - m4_foreach([x], [], [foo]) expanded to `foo', while
6516 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6517 This bug has been fixed:
6519 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6520 expand to an empty string; print error msg if called without
6522 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous

6533 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6534 swallow records with more than 99 fields.
6535 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6536 parse the long line.
6538 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6540 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

6645 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
6648 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6650 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6651 argument to m4_foreach. I guess it was necessary in the past,
6652 but I think it's a no-op now.
6654 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6656 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6657 ``cat <<_ACEOF'' commands to one.
6658 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6659 * lib/autoconf/status.m4: On various places, use expr instead of
6661 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6662 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6663 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6665 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6666 the wrong patterns between ``case'' and ``esac.'' The previous
6667 code had false positives.
6669 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6671 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

6726 2005-05-11 Stepan Kasal <kasal@ucw.cz>
6728 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
6729 for absolute directory names in one loop.

6731 abbreviations of --version and --debug.
6733 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
6735 * doc/autoconf.texi (Autoconf Language): Be more precise about
6736 quoting rules. Problems noted by Stepan Kasal.
6737 Also, throughout this document, be more careful about white space.
6738 "blank", "white space", and "space" all have different meanings
6739 and we should be careful to say what we mean.
6741 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6743 Fix C++ related problems reported by Werner Lemberg.
6744 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

6746 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
6747 avoid problems with C++ and throw.
6748 * tests/compile.at: .cpp, not .cc.
6750 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
6752 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6754 * doc/autoconf.texi (Generic Functions): Typos.
6756 2005-05-02 Gary V. Vaughan <gary@gnu.org>
6758 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
6759 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
6760 set by latest automake.
6762 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6764 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6765 outputs 0 on GNU/Linux these days.
6767 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6769 * doc/autoconf.texi (Autoconf Language): Add more description
6770 about quoting heuristics.
6771 (Limitations of Builtins): Describe "set -" problems.
6773 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6775 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6778 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6779 by AC_DEFINE; it was a mistake.
6780 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6782 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6784 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6786 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6788 * doc/autoconf.texi (External Software): Quadrigraphs are not
6789 processed correctly in AS_HELP_STRING; avoid this in the examples.
6790 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6791 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6792 comment and reduce m4_default([foo], []) to [foo].
6793 (m4_strip): Update the explanation.
6795 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6797 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6798 Remove core.conftest.* too; it's generated by Tru64 5.1.
6799 Problem reported by Jennis Pruett.
6800 * lib/autoconf/functions.m4
6801 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6802 Don't bother to remove core files; AC_RUN_IFELSE should do that
6805 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6807 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
6809 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
6811 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
6812 Report from Horst Wente.
6814 2005-04-15 Stepan Kasal <kasal@ucw.cz>

6821 * doc/autoconf.texi (External Software, Package Options): Add
6822 examples showing how to implement --with-* and --enable-* options.
6824 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6826 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6827 as well as configure.in. Problem reported by Gregorio Guidi.
6829 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6831 * doc/autoconf.texi (Particular Functions): Use gnulib's current

6844 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6845 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6847 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6849 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6850 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6851 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6852 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6853 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6855 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6857 * NEWS: The configure command now warns you if you attempt to use
6858 a directory whose name contains a special character like space,
6860 * doc/autoconf.texi (Installation Directory Variables): Allow
6861 "," in file names. Do not use \@; it's not a portable regexp.
6862 * bin/Makefile.am (edit): Likewise.
6863 * lib/Makefile.am (edit): Likewise.
6864 * tests/Makefile.am (edit): Likewise.
6865 * tests/semantics.at: Likewise.
6866 * tests/torture.at: Likewise.
6867 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
6868 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6869 * doc/autoconf.texi (File System Conventions): Warn about
6870 unportable file names.
6871 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6873 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6874 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6875 ac_pwd, and quote srcdir.
6876 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6878 * doc/autoconf.texi: Fix some systematic formatting problems.
6879 ".)" needs a following @: if not at the end of a sentence, and
6880 similarly for "!)". "etc." should be preceded by a comma.
6881 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6883 2005-03-22 Bruno Haible <bruno@clisp.org>
6885 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6886 argument is often called 'build-aux'.
6888 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6890 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6891 macro AC_TRY_LINK is obsolete.
6892 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6895 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6897 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6898 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6899 from a Common Lisp's `cl'.
6900 (AC_PROG_CXX): Behave according to the documentation: don't
6901 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6902 make the variable CCC precious; use `cl.exe', not `cl'.
6904 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6905 Alexandre Duret-Lutz <adl@gnu.org>
6907 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6908 /dev/null, as "configure" shouldn't read stdin, and this insulates
6909 us from problems (e.g., when testing for "cl"). Also, do this
6910 redirection before invoking "hostname" or "uname", and keep the
6911 original input stream available via...
6912 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6913 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6914 bother with "</dev/null" since it's now done at the top of
6916 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6917 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6918 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6919 * doc/autoconf.texi (File Descriptor Macros): New section.
6920 (Printing Messages): Mention it.
6921 * tests/base.at (Input/Output): New test.
6923 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6925 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6926 newline if neither \c nor -n work, as that would output two
6927 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6929 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6931 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6932 This causes that any required macros inside will get before the if.
6933 * doc/autoconf.texi (autom4te.cache): A typo.
6935 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6937 Undo previous change, except keep the change to
6938 lib/autoconf/programs.m4 that replaced grep with shell
6939 pattern-matching. This is because net-snmp configure reads stdin.
6940 Reported by Noah Misch.
6942 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6944 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6945 from /dev/null, as "configure" shouldn't read stdin, and this
6946 insulates us from problems (e.g., when testing for "cl").
6947 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6948 before invoking "hostname" or "uname".
6949 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6950 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6951 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6952 "</dev/null" since it's now done at the top of 'configure'.
6953 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6954 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6955 Also, replace grep with shell pattern-matching, to save a process.
6957 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6959 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6960 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6961 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6964 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6966 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6967 grep -q isn't portable. Improve grep -s explanation.
6968 Problem reported by Dan Manthey.
6970 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6972 * doc/autoconf.texi (Special Shell Variables): Clarify
6973 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6975 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6977 * doc/autoconf.texi: Use @acronym for DJGPP.
6978 Fix some @code's that should have been @env's, and vice versa.
6979 Sort environment variable names.
6980 Mention that shells no longer inherit IFS.
6981 Don't recommend PATH_SEPARATOR=';' so strongly.
6982 Mention that $RANDOM might expand to the empty string.
6983 "symlink" and "soft link" -> "symbolic link".
6984 Improve mktemp description (reported by Bruno Haible).
6986 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6988 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6989 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6991 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6994 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6996 * NEWS: Mention AT_COPYRIGHT.
6998 * tests/local.at (AT_CMP): Use diff directly on input files rather
7001 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
7002 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
7004 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7005 and Paul Eggert <eggert@cs.ucla.edu>
7007 * tests/autotest.at (Empty test suite): New test.
7008 * tests/torture.at (Substitute and define special characters)
7009 (Substitute a 2000-byte string, Define to a 2000-byte string)
7010 (Substitute a newline, Define a newline): New tests.
7012 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7014 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
7015 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
7016 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
7017 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
7018 (Standard regular expressions): New test.
7019 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
7020 excess test name quoting.
7021 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
7022 CPPFLAGS to `configure' instead of setting it in `configure'.
7024 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
7025 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
7028 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
7029 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
7031 * tests/local.at (AT_CMP): New macro.
7032 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
7033 (AC_SAVE_STATE): Move environment grep...
7034 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
7035 (AT_CONFIG_CMP): New macro.
7036 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
7037 * tests/c.at (Extensions): Do not exit early.
7038 * tests/atlocal.in: Inherit $GREP.
7040 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
7041 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
7043 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
7044 (AC_COPYRIGHT): Factor header comment portion out and move into...
7045 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
7046 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
7047 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
7049 * tests/local.at: Add Autoconf test suite copyright notice.
7050 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.

7057 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
7059 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
7060 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
7062 Try not to generated lines of unlimited length, as POSIX places a
7063 2047-byte limit on line length of portable text files.
7064 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7065 Use newline as a separator, not space.

7067 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
7070 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7072 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
7073 as_func_*. Add test to check whether positional parameters
7074 are restored after function return.
7076 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
7078 * doc/autoconf.texi (Special Shell Variables): Mention _,
7079 BIN_SH, DUALCASE. Say that variables other than "status" are safe
7080 if they contain a lower-case letter. The DUALCASE problem was
7081 reported by Ralf Wildenhues.
7083 * bin/autoconf.as: Don't exit with status 0 after write failure
7084 with --help or --version.

7123 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7124 Update the long comment explaining it.
7126 m4_require no longer writes an ``is required by'' line to the
7127 execution stack. It contains only one bit of non-redundant
7128 information: that the macro was required, not called. And even
7129 this bit is useless in most situations: have you ever met a macro
7130 which both calls and requires the same macro?
7132 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7133 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7141 * tests/m4sugar.at (m4_require): Expect output without the
7142 ``is required by'' messages.
7144 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

7181 Warn about newline stripping in `` and $(). Update Solaris
7183 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7184 X insulates us from future changes to Posix.

7212 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

7238 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7239 stored in _m4_divert_diversion or _m4_divert_dump.
7240 (m4_divert_pop): When the parameter is given, compare the symbolic
7241 name with the last diversion pushed on the stack. Previously, the
7242 current diversion was compared with the numeric value of the
7243 diversion given as the parameter.
7244 (m4_require): If the macro hasn't been expanded yet, call ...
7245 (_m4_require_call): this new macro.

7552 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7553 "char c = '\200';" rather than "char c = 0x80;" as the
7554 latter doesn't conform to the strict C standard due to
7555 overflow on signed char hosts.
7557 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
7558 to -qlanglvl=ansi. We don't want to disable extensions.
7560 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
7562 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
7563 (Using Autotest, testsuite Scripts, Writing testsuite.at):

7614 simplify the examples and improve their quoting.
7616 2004-11-13 Stepan Kasal <kasal@ucw.cz>
7618 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
7619 the $1_found variable, don't test whether the file is executable;
7620 Both things are checked ...
7621 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
7622 the former ``test -f''.
7623 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
7625 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

7635 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
7637 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
7638 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
7639 variants", "Unix", and some related minor wording fixups.
7641 (Shellology, Special Shell Variables): Document that the Zsh
7642 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
7643 to Alexandre Duret-Lutz for this info.

7652 of putenv. Problem reported by Michael Wardle.
7654 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
7656 * doc/autoconf.texi (auindex): New macro.
7657 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
7658 Problem reported by Stepan Kasal.
7660 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
7662 Fix problems reported by Andreas Buening in:
7663 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
7664 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
7666 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
7667 readable; it's not true in OS/2-emx.
7669 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
7671 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7672 "/usr/include", clear ac_x_includes instead of leaving it as "no"
7673 (trivial change). Problem and patch reported by Andrew Church in:
7674 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7676 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
7678 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

7703 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
7704 texinfo.tex for now (done by hand now).
7705 * Makefile.maint (wget_files, cvs_files):
7706 Remove ansi2knr.c; nobody uses it.
7707 (ansi2knr.c-url_prefix): Remove.
7708 (cvs-update): Fix test for failure. I don't know why it ever
7711 * doc/autoconf.texi: Update URLs, some of which went stale.
7712 Use @uref rather than @href.
7714 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
7715 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
7717 * config/config.guess, config/config.sub, config/elisp-comp,
7718 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7719 doc/fdl.texi, doc/standards.texi: Sync with master copy.
7721 * NEWS, TODO, configure.ac, bin/autoscan.in,

7727 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
7728 tests/tools.at, tests/torture.at:
7729 Use "file name" rather than "filename" or "path",
7730 to be consistent with the terminology of the GNU coding standards.
7732 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7734 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7735 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7736 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7737 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7739 More fixes to support spaces in the name of the build directory.
7740 This isn't a complete fix but it's an improvement.
7742 * bin/autoconf.as (autom4te_options): New var.
7743 Use it instead of appending to AUTOM4TE, so that we can allow
7744 spaces in the build directory's absolute name.
7745 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7746 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
7747 AT_CHECK_NOESCAPE): Likewise.
7748 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
7749 main program): Likewise.
7751 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
7753 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

7759 * doc/autoconf.texi (Function Portability): Document isinf and
7760 and isnan. From a suggestion by Kevin Ryde.
7762 * lib/Autom4te/General.pm (END): Return correct exit status even
7763 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7765 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7767 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7768 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7769 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7771 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7773 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7774 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7775 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7776 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7777 * lib/autom4te.in (Automake-preselections): Preselect
7778 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7780 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7782 * lib/autom4te.in (Automake-preselections): Preselect
7783 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7786 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7788 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7790 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7791 Document problem with "`""`" in pdksh POSIX mode.
7793 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7795 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7796 with pdksh, too. Problem reported by Patrick Welche via
7798 * doc/autoconf.texi (Shellology): Note that set -o posix is
7799 useful for pkdsh, too.
7801 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7803 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7804 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7805 Don't fail if ENV or BASH_ENV is readonly.
7806 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7807 etc. are read only. Problem reported by Ludovic Courtes.
7809 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7811 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7812 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7815 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7817 * doc/autoconf.texi (File System Conventions): Warn about
7818 names like "aux". Problem reported by Eric Blake.
7820 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7821 by zero instead of array size, so that we can use any arithmetic
7822 constant expression (instead of requiring an integer constant
7823 expression). This allows us to test expressions like DBL_MAX <
7824 LDBL_MAX, which didn't conform to the C standard using the old
7826 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7827 now that we can do floating-point tests at compile time.
7829 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7831 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7832 and LDBL_EPSILON, as the resulting expression isn't an
7833 integer constant expression and violates the C standard.
7834 Problem reported by Nelson H. F. Beebe. Also, check
7835 for "L" suffix, and check that long double doesn't have
7836 worse range or precision than double, that mixed-mode
7837 arithmetic doesn't generate a diagnostic, that double
7838 constants fit in long double.
7840 2004-06-03 Kevin Ryde <user42@zip.com.au>
7842 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7843 malloc(0) and realloc(NULL,size).
7845 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7848 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7850 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7851 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7854 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7856 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7857 can be rewritten using if-then-else. Suggested by Bruno Haible.
7859 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7861 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7862 Problem reported by Stepan Kasal.
7864 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7866 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7867 change). Patch reported by Ralf Wildenhues in
7868 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7870 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7871 function F exists if the compiler and linker let you compile an
7872 expression like (F != 0). Recent versions of GCC optimize away
7873 the reference to F in that case, since every function address must
7874 be nonzero, so the link succeeds even if F does not exist.
7875 Problem reported by Manu in
7876 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7878 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7879 "Unix". Many uses changed.
7880 (Limitations of Builtins): Explain better why the ! command isn't
7883 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7885 * lib/autom4te.in (Automake-preselections): Preselect
7886 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7888 2004-05-19 Kevin Ryde <user42@zip.com.au>
7890 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7891 referencing AC_FUNC_STRERROR_R.
7893 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7894 note pessimistic assumption when cross compiling.
7896 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7898 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7899 (until 2004) invoked subcommands with sh -e, contra POSIX.
7900 Reported by Kevin Ryde.
7902 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7904 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7905 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7906 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7907 `test -f " /usr/bin/grep"', which _always_ failed.
7908 (AC_PROG_SED): Ditto bogus PATH fix.
7909 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7910 requires that grep correctly supports _multiple_ `-e' options, rather
7911 than stating only that grep should accept `-e'.
7913 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7915 Port to C99, which requires that 'exit' be declared.
7917 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7918 to ensure that stdlib.h is included.
7919 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7920 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7921 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7922 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7923 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7924 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7925 when using 'exit' in a test; C99 requires that 'exit' be declared.
7927 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7929 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7930 now prefers 'grep' implementations that accept -e.
7931 (Limitations of Usual Tools): Describe problems of traditional
7932 egrep and fgrep with long input lines, and of traditional grep
7934 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7935 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7936 All callers changed. Append /usr/xpg4/bin to the PATH, for
7938 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7939 the user with complaints about multiple -e options.
7940 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7941 Define it with AC_PROG_GREP.
7942 * configure.ac (AC_PROG_GREP): Add.
7943 * lib/freeze.mk (GREP): New macro.
7945 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7947 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7948 a possible candidate only after all others fail, rather than
7949 consulting it first. This improves backward compatibility by
7950 better reflecting the way shell selection occurred in previous
7951 versions of Autoconf, and should help to avoid triggering latent
7952 problems in other packages, such as the one in Automake where zsh
7953 is not handled robustly:
7954 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7955 Although it is not Autoconf's responsibility to work around
7956 problems in Automake, it nevertheless makes sense to avoid
7957 introducing unnecessary incompatibilites.
7959 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7960 Gary V. Vaughan <gary@gnu.org>
7962 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7963 how deeply nested we are when a suitable tool is found, set the
7964 ac_path_TOOL_found flag.
7965 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7966 nested we are in this macro. Break out of all 3 nested loops if
7967 ac_path_TOOL_found is set.
7969 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7971 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7972 of the _AS_PATH_WALK loop too if GNU flavor is found.
7974 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7976 * doc/autoconf.texi (Limitations of Make): Update documentation
7977 for `$<'. New entry `Long lines', based on a report from Simon
7978 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7979 paragraph about DJGPP, based on a mail from Richard Dawe.
7981 2004-04-20 Paul Eggert <eggert@twinsun.com>
7983 * tests/c.at (C keywords): Don't assume that GCC supports
7984 "restrict" and "inline", as sufficiently-old GCC versions do not
7985 (also, GCC configured to be in pedantic C89 mode does not).
7986 Problem reported by Sumit Pandya in:
7987 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7989 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7990 consider -g to work if it generates warnings when plain compiles
7991 don't. Problem reported by Braden McDaniel in:
7992 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7994 * doc/autoconf.texi (Slashes): New section, to document a problem
7995 reported by Jim Meyering in:
7996 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7998 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7999 linker output files before linking, to work around IRIX 6 linker bug.
8000 Problem reported by Rainer Orth in:
8001 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
8003 2004-04-20 Gary V. Vaughan <gary@gnu.org>
8005 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
8006 best tool so far counter rely on the tool path variable name to
8007 avoid checks for one tool being affected by the results of running
8008 the length check on a previous tool.
8010 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional

8148 AC_SUBST provides no portable way to escape literal newlines.
8150 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8151 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8152 Darwin uses -lcrt2.o and there's little point to cataloging all

8229 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8230 2003 (except 1997) to the list of copyright years. This undoes
8231 the 2003-05-22 change, which removed the older years from the list.
8232 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

8245 _AC_PROG_GREP, and AC_PROG_SED.

8278 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8279 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8280 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8281 not <inttypes.h>. Problem reported by Tim Mooney in

8283 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8286 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8287 otherwise "make check" fails because it forbids cmp (I guess
8288 because cmp treats files as binary on DOS-like systems).

8303 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8304 -std1 disables some useful extensions on Tru64. Problem reported

8310 * doc/autoconf.texi (Programming in M4sh): Document that
8311 AS_MKDIR_P succeeds if the destination is a symbolic link
8312 to an existing directory.
8313 (Limitations of Usual Tools): Note that mkdir -p might not
8314 succeed on symlinks to directories.

8334 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
8335 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
8336 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
8337 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
8338 AC_COMPILE_IFELSE, since we now assume our caller invokes
8339 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
8340 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
8341 of AC_RUN_IFELSE; this avoids the warning mentioned above.
8342 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
8344 2004-01-07 Paul Eggert <eggert@twinsun.com>
8346 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
8347 `"'...'"`, as it's confusing (and I suspect it may not work on
8348 some platforms). The code was incorrect anyway, as it assumed
8349 that \$ evaluated to itself in that context. Reported by
8350 Alexandre Duret-Lutz.
8352 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
8354 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

8384 Bug reported by David Relson in
8385 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
8387 * Makefile.am (autom4te-update):
8388 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

8404 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
8405 -c -o might not work. From a suggestion by Kevin Ryde.
8406 (C Compiler, Generating Sources, Limitations
8407 of Usual Tools, Limitations of Make, Making testsuite Scripts):
8408 Don't put '-o' after non-options, as POSIX doesn't allow this.
8409 Mention that cc's name might be gcc or c89 or whatever.
8411 2004-01-04 Kevin Ryde <user42@zip.com.au>

8420 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
8422 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
8423 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
8424 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
8425 explanation clearer.

8436 * tests/atlocal.in: Store the result here.

8706 Problems reported by Eric Sunshine.
8708 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8710 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
8711 -mGLOB_options_string stuff for Intel ifc, which can cause
8712 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
8713 pattern-matching instead of grep.

8733 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
8735 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8736 cache variable instead of $G77 to decide whether to include -O2,
8737 since $G77 is specific to Fortran 77.
8739 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8741 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
8742 free" flag. Re-order flags tested into rough order of popularity.
8744 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8746 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
8747 arguments so that it can be used with syntax identical to
8748 AC_PROG_F77, and so that we can more easily decide to
8749 remove/deprecate the DIALECT optional argument in the future if it
8751 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
8752 non-freeform-supporting compilers. Document freeform flags.

8815 Problem reported by Lars J. Aas in
8816 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
8817 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8818 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

8821 2003-09-26 Akim Demaille <akim@epita.fr>
8823 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8824 directory for AC_CONFIG_COMMANDS' first argument exists.
8825 This makes valid the invocation of _AC_SRCPATH that follows.
8826 Reported by Eric Sunshine.
8827 * doc/autoconf.texi (Configuration Commands): Adjust.
8829 2003-09-26 Akim Demaille <akim@epita.fr>

8850 The test suite are sometimes assigning timings incorrectly.
8851 Reported by Henk Krus.
8852 Diagnosed by Nicolas Joly.
8854 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8856 Instead of making AT_help a sequence of assignments to grow
8857 $at_help_all, just make AT_help_all be the growing contents of
8858 $at_help_all, and make a single assignment in...
8860 (at_times_skip): Flip the meaning and rename as...
8862 (AT_INIT): When summarizing the test that ran, remove
8863 $at_times_file after use, and check it is present before trying to

8870 * bin/Makefile.am (edit): Handle '@configure_input@'.
8871 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8872 (ifnames): chmod -w.
8873 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8874 executables, not bin/ executables! Otherwise all the magic needed
8875 to find non installed files is turned off. This caused a failure
8876 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8877 as found in its environment (sent by tests/autoreconf): pointing
8878 to bin/autom4te that could not find its files.
8879 * tests/mktests.sh: Force the replacement of generated files, for
8880 the sake of "mv" program that are interactive when overwriting a
8882 * config/install-sh: Upgrade from CVS Automake.
8884 2003-09-23 Paul Eggert <eggert@twinsun.com>

8927 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8928 willing to edit the output files.
8930 2003-09-10 Akim Demaille <akim@epita.fr>

8973 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8975 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8977 Add support for newer Fortran dialects. The F77 interface is
8978 unchanged, and continues to support Fortran 77. New FC macros
8979 correspond to all the old F77 macros, with output variables FC,
8980 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8981 available dialect, but older dialects can be specified. There are
8982 new macros AC_FC_SRCEXT to set the source extension, and
8983 AC_FC_FREEFORM to accept free-form source files.
8985 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8987 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

9109 2003-08-21 Akim Demaille <akim@epita.fr>
9111 First stab at preserving warnings between calls to autom4te,
9112 including when the cache is used.
9114 There are still several issues: (i) there are too many runs of m4
9115 (one for include, one for warnings, and some more), (ii) warnings
9116 spreading on several lines are not handled gracefully, (iii) the
9117 code meant to have the call stack display for errors does not work
9118 (its handling should move from m4 to autom4te).
9120 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9122 (@preselect): Add m4_warn.
9123 ($exit_status): Remove, use $exit_code.
9124 ($help): Use Autom4te::ChannelDefs::usage.
9125 (&handle_m4): No longer define the m4_warnings.
9126 At each run, extract and report the warnings.
9127 Always cache the result, including if the exit status is on
9128 failure, since if nothing changes, we should result in the same
9129 failure, hence we can use the cache.

9131 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9133 (m4_warn): Redefine as a do-nothing: it is its invocation that
9134 matters, as warnings are now reported via traces.
9135 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9136 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9137 the latter reveals calls to the former.
9141 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

9174 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9175 * bin/autom4te: Adjust.
9176 In particular, be Autoconf tools are really silent when properly
9177 working, bind the verbosity of the 'note' channel to $verbose.
9178 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

9242 shorter column three. Add DESCRIPTION to log file content.

9300 2003-06-23 Akim Demaille <akim@epita.fr>
9302 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9303 not all of them. This fixes 1. the fact that when testing
9304 Autoconf there are many many config.log, 2. the incorrect use of
9305 top_srcdir to find config.log.
9306 Don't mix the detailed output of failed test with the summary of
9307 failures. Rather, append detailed log afterwards.

9426 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9427 Remove `#include <stdlib.h>' from the list; we should never
9428 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9429 resulting namespace pollution would cause other tests to fail.
9430 Configure scripts run with some older versions of g++ and HP's
9431 aCC would fail due to such an #include. Problems reported by
9432 Matthew Mueller in <http://bugs.debian.org/120704> and by
9434 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9435 In the test, use the test declaration before including <stdlib.h>,

9445 Overhaul Autotest's logging: generate separate log files
9446 in testsuite.dir/NNN/testsuite.log, and append them to
9447 testsuite.log instead of re-running the test verbosely.
9449 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9450 file descriptor, write 0 to at_status_file instead of setting
9451 at_status=0, initialize some new variables (at_status_file,
9452 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9453 to rerun the tests, instead append the at_group_log to the
9454 at_suite_log when a test fails.
9455 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9456 with the AS_MESSAGE_LOG_FD redirected to stdout.
9457 (AT_CLEANUP): save the output status in $at_status_file
9458 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9460 (AT_CHECK): since tests are run with a redirected stdout,
9461 and used to be re-run in verbose mode, turn some $at_verbose
9462 into echo, and don't redirect the output of testing stdout

9583 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
9586 2003-05-06 Akim Demaille <akim@epita.fr>
9588 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9589 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9590 by aclocal.m4 is changed it might require the importing of another
9591 m4 extension file, i.e., aclocal must be run.
9593 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9594 (&parse_args): Use --force with aclocal if required and supported.
9595 (&autoreconf_current_directory): Use &run_aclocal.

9612 (AT_CLEANUP): Add `;' to end of at_help_all.
9613 (AT_INIT): Allow --keywords to be specified more than once. When
9614 grepping $at_help_all for keywords, use the field and keyword

9711 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
9712 use new diversions in preparation for accepting new arguments and
9713 allowing scripting around tests.
9714 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
9716 2003-03-26 Derek Price <derek@ximbiot.com>
9718 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of

9766 about `$<' in inference rules, it was a bogus interpretation of
9767 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
9768 Tru64 make in the "target lookup" section.
9769 (Automake): Automake 1.5+ no longer requires special tools to be
9770 present on the developer's host.
9772 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
9774 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
9775 to a shell that can handle redirection or quoting correctly.
9776 Override SHELL with the shell detected by configure.
9777 Use of $^O suggested by Tim van Holder.
9778 * bin/autom4te.in (BEGIN): Likewise.
9779 * bin/autoreconf.in (BEGIN): Likewise.
9780 * bin/autoscan.in (BEGIN): Likewise.

9810 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
9811 to fix a mismatch between example and discussion.
9813 2003-02-24 Kevin Ryde <user42@zip.com.au>
9815 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
9816 format starting with "-".
9818 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

9825 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9826 compiler says yeah, but preproc says nope, compiler is right.
9827 Conversely, prompt the reader to send a bug report to the
9828 maintainers of the package, not of Autoconf.
9830 2003-02-20 Klee Dienes <kdienes@apple.com>
9832 * bin/autoreconf.in (autoreconf_current_directory): Properly
9833 handle an empty aclocal.m4.

9841 2002-12-23 Paul Eggert <eggert@twinsun.com>
9843 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9844 innocuous variant befor including <limits.h> or <assert.h>. This
9845 works around a bug reported by Albert Chin: HP-UX 11i
9846 (and earlier versions) have a <limits.h> that declares
9847 gettimeofday and many other functions.
9849 2002-12-03 Paul Eggert <eggert@twinsun.com>
9853 * NEWS, configure.ac: Update version.
9855 * doc/fdl.texi: Upgrade to FDL version 1.2.
9857 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9858 nontrivially in main's body, so that f's external declaration is
9859 not optimized away in AIX. This should fix the bug reported by
9861 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9863 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9864 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9865 defined, to support freestanding compilers. This should fix the
9866 bug reported by Momchil Velkov in
9867 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9869 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9870 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
9871 obsolete AC_CHECK_TYPE. The missing empty arg was reported
9872 by Simon Josefsson in
9873 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
9875 * Makefile.maint (www-gnu): New macro.

9877 the location has moved.
9879 2002-12-02 Martin Frydl <martin@systinet.com>
9881 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
9882 \(.*\) match is too long and there is something more to be checked.
9883 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

9901 Update from masters.
9903 2002-11-14 Akim Demaille <akim@epita.fr>
9905 * Makefile.maint: Sync with Bison, i.e.:
9906 (po-check): Scan .l and .y files instead of the
9907 .c and the .h files that they generate. This fixes the bug
9908 reported by Tim Van Holder in:
9909 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9910 Look for N_ as well as for _. Try to avoid matching #define for
9914 2002-11-14 Akim Demaille <akim@epita.fr>
9916 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9917 From Paul Eggert and Albert Chin-A-Young.
9919 2002-11-14 Akim Demaille <akim@epita.fr>
9921 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9922 From Paul Eggert and Albert Chin-A-Young.
9924 2002-11-14 Kevin Ryde <user42@zip.com.au>
9926 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9927 than assigning in main, to avoid HP cc +O3 optimizing it away.
9929 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9931 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9932 option. Process --recheck after parsing all options. Pass -q
9933 option to configure on --recheck.
9934 (AC_OUTPUT): Pass -q from configure to config.status.
9935 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9936 arguments to record.
9937 * doc/autoconf.texi (config.status Invocation): Document
9938 config.status -q option.
9940 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9942 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
9943 Makefile.in if Makefile.am exists.

9956 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9957 declaration in extern "C" too.
9958 Reported by Roberto Bagnara.
9960 2002-11-06 Akim Demaille <akim@epita.fr>
9962 * tests/torture.at (Configuring subdirectories): Don't use grep
9964 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9965 Reported by Ezra Peisach.
9967 2002-11-05 Akim Demaille <akim@epita.fr>
9969 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9971 We _have_ to stop using the old compatibility scheme that tried to
9972 avoid useless backslashes because Libtool 1.4.3 contains a
9973 AC_DEFINE([error_t], [int],
9974 [Define to a type to use for \`error_t' if it is not
9975 otherwise available.])
9976 We _have_ to quote the single quote and backslashes with \. The
9977 old compatibility scheme saw that ` was backslashed, and therefore
9978 did not quote the single quote. Hence before this patch, Autoconf
9979 was not compatible with Libtool.
9981 2002-11-04 Paul Eggert <eggert@twinsun.com>
9983 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

9994 * config/texinfo.tex: Update.
9996 2002-11-03 Akim Demaille <akim@epita.fr>
9998 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
10000 (&autoreconf): here.
10001 ($help, $make, &parse_args, &autoreconf_current_directory):

10370 Reported by Alexandre Duret-Lutz.
10372 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

10377 (&up_to_date): If a file that was included according to the cache

10392 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
10393 if some file was changed instead of `print'.
10394 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

10428 file name to enable parallel executions.
10429 From Sam Varshavchik.
10431 2002-10-08 Akim Demaille <akim@epita.fr>
10433 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10434 aclocal invocation, as Gettext macros might not be visible to
10436 Instead of blindly running autopoint, scan configure.ac (not the
10437 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10438 Reported by Paul D. Smith.
10440 2002-10-08 Paul Eggert <eggert@twinsun.com>
10442 Work around problems found when POSIXLY_CORRECT=1 is set.
10443 None of this seems to have anything to do with POSIX, really,
10444 but it's how Perl getopt works.
10445 * bin/autom4te.in (parse_args): Configure GetOpt with
10447 * doc/autoconf.texi (Invoking autom4te):
10448 --warning -> --warnings.

10470 * tests/torture.at (Configuring subdirectories): Be robust to
10471 users who use config.site to require for a cache: in this case,
10472 the two last configure runs, using two different sets of
10473 arguments, trigger a legitimate error.
10475 2002-09-28 Akim Demaille <akim@epita.fr>

10508 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10509 (.m4.m4f): Don't pass --prepend-include, since that's done by
10510 tests/autom4te itself.
10511 * lib/autoscan/Makefile.am: Include freeze.mk.
10512 (autoscan.list): New target --this file is no longer a source.
10513 (autoscan.pre): New file.
10515 2002-09-28 Akim Demaille <akim@epita.fr>
10517 * bin/autoscan.in (@kinds): Make them singular.
10519 (&init_tables): When --debug, report the list of rules to ease
10520 tracking changes in autoscan.list.
10521 * lib/autoscan/autoscan.list (function): Strip comments, sort.
10523 2002-09-28 Akim Demaille <akim@epita.fr>

10529 * bin/autoscan.in (&init_tables): Adjust.
10531 2002-09-28 Akim Demaille <akim@epita.fr>
10533 * lib/autoscan/functions, lib/autoscan/headers,
10534 * lib/autoscan/identifiers, lib/autoscan/makevars,
10535 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10536 `functions' line is now prefixed with `function:'.
10537 * bin/autoscan.in (&init_tables): Adjust.
10539 2002-09-28 Akim Demaille <akim@epita.fr>
10541 From now on, autoscan files must always map a macro name to a
10542 word: there is no `default' macro for autoscan.
10544 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10546 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10549 2002-09-28 Akim Demaille <akim@epita.fr>
10551 * bin/autoscan.in (%c_keywords): Remove.
10552 (&used): Keep only track of the words we might be interested in.
10553 (&output_kind): It is no longer needed to look for non active

10567 Thanks to Bill Moseley and Paul Eggert.
10568 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
10569 the tmpdir must be created.
10570 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
10571 dir be in the build tree, instead of $TMPDIR.
10573 2002-09-27 Akim Demaille <akim@epita.fr>
10575 * bin/autoscan.in: Improve the comments.
10576 (&parse_args): Drop obsolete undocumented options.

10584 Reported by Ralf Corsepius.
10585 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10587 2002-09-26 Akim Demaille <akim@epita.fr>
10589 Single suffix rules and seperated dependencies are not portable.
10591 * doc/autoconf.texi (Installation Directory Variables): Update.
10592 (Limitations of Make): Some about `Single Suffix Rules and
10593 Separated Dependencies'.
10594 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)

10597 2002-09-25 Paul Eggert <eggert@twinsun.com>
10599 * BUGS (Interoperability bugs): New section. Mention libtool
10600 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10602 2002-09-24 Paul Eggert <eggert@twinsun.com>
10604 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10605 make handles suffix-rules differently from GNU make.
10607 * bin/Makefile.am (SUFFIXES, .in): Remove.
10608 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
10609 Move the body of the old .in rule here.
10611 2002-09-16 Akim Demaille <akim@epita.fr>
10613 i960 compilers create `b.out' files by default.
10614 Reported by Ralf Corsepius.
10616 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10617 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10619 2002-09-13 Paul Eggert <eggert@twinsun.com>
10621 * doc/autoconf.texi (Particular Headers): Remove obsolete
10622 reference to `struct timezone' in the description of

10630 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10631 * Makefile.am: Adjust.
10633 2002-09-13 Akim Demaille <akim@epita.fr>
10635 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10636 reading config.log when the compiler is rejected.
10637 Suggested by Guido Draheim.
10639 2002-09-13 Akim Demaille <akim@epita.fr>
10641 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10642 (chdir_init) might hang when stat'ing mounted directories.
10643 Reported by Vance Shipley.
10645 2002-09-12 Akim Demaille <akim@epita.fr>
10647 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10650 2002-09-12 Akim Demaille <akim@epita.fr>
10652 * doc/autoconf.texi (Defining Symbols): Present two different
10653 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10654 difference between 1 argument calls, and 2-3 argument calls.
10656 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10658 * doc/autoconf.texi: Review grammar and punctuation.
10660 2002-09-11 Paul Eggert <eggert@twinsun.com>
10662 * doc/autoconf.texi: Fix minor formatting, spelling, and
10664 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10665 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10668 2002-09-11 Akim Demaille <akim@epita.fr>
10670 * doc/autoconf.texi (Questions): Rename as...
10672 (Defining Directories): New.
10674 2002-09-09 Akim Demaille <akim@epita.fr>
10676 * doc/autoconf.texi (Making testsuite Scripts): Update.
10677 Suggested by Nishio Futoshi.
10679 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10681 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10682 plain `@' is wanted.
10684 2002-09-09 Akim Demaille <akim@epita.fr>
10686 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10687 `duplicates', since the algorithm was too naive and could keep
10688 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10689 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10690 Reported by Ralf Corsepius.
10691 * tests/torture.at (Configuring subdirectories): Exercise these
10694 2002-09-09 Akim Demaille <akim@epita.fr>
10696 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10697 looking for a replacement file.
10698 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10699 directory is relative.
10700 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10701 directory definition.
10702 Reported by Andreas Schwab and Jim Meyering.
10704 2002-09-06 Akim Demaille <akim@epita.fr>
10706 * doc/autoconf.texi (Setting Output Variables): Clarify what
10707 precious variables are.
10708 Suggested by Pontus Skoeld.
10710 2002-09-05 Akim Demaille <akim@epita.fr>
10712 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10713 (ifnames, autoscan, autom4te): Since we don't only depend on
10714 configure.ac variables (such as VERSION etc.), but also on prefix
10715 and so forth, depend on Makefile, not configure.ac.
10716 Reported by Alexandre Duret-Lutz.
10717 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10719 2002-09-05 Kevin Ryde <user42@zip.com.au>
10721 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10722 doesn't seem to be confined to ia64, just say "some versions".
10724 2002-09-04 Akim Demaille <akim@epita.fr>
10726 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10728 * Makefile.am (maintainer-clean-local): Remove.
10729 (MAINTAINERCLEANFILES): Remove COPYING.
10731 2002-09-03 Paul Eggert <eggert@twinsun.com>
10733 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10734 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10737 2002-09-03 Akim Demaille <akim@epita.fr>
10739 * configure.ac: Bump to 2.53d.
10740 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10741 as of today, on Automake's team suggestion.
10743 2002-09-03 Akim Demaille <akim@epita.fr>
10747 2002-09-02 Akim Demaille <akim@epita.fr>
10749 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10751 * configure.ac: Disable SITE_MACRO_DIR.
10753 2002-09-02 Jim Meyering <meyering@lucent.com>
10755 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10756 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10757 Also, tweak grammar: s/make sure to/be sure to/.
10759 2002-09-02 Paul Eggert <eggert@twinsun.com>
10761 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10762 directory names are generally preferable to physical names.
10764 2002-09-02 Akim Demaille <akim@epita.fr>
10766 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10767 Reported by Raja R. Harinath.
10768 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10769 * bin/autoupdate.in: Use error instead of die.
10771 2002-09-01 Paul Eggert <eggert@twinsun.com>
10773 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10774 ordinary shell concatenation rather than echo+tr+sed command that
10775 runs afoul of a long-line-related sed bug in Solaris 8.
10777 * bin/autoheader.in (parse_args): --warning -> --warnings.
10779 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10780 stdout, as traditional "ls" does.
10781 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10782 _AC_COMPILER_EXEEXT_O): Likewise.
10783 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10785 * bin/autoconf.as: Add --prepend-include option. This patch was
10786 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10787 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10789 * bin/autoconf.in, configure: Regenerate.
10791 * doc/autoconf.texi (Special Shell Variables): Mention
10792 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10794 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10795 MAILPATH and set PS1, PS2, PS4 to default values, to work
10796 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10797 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10798 the Autoconf documentation specifies; fall back to "unset" only if
10799 this fails. Use a shell for-loop for this rather than an m4 loop,
10800 to shorten the output script.
10802 2002-08-30 Paul Eggert <eggert@twinsun.com>
10804 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10805 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10806 for the CDPATH problem. Document PWD.
10807 (Limitations of Builtins): Document the problem that "cd $foo" and
10808 "ls $foo" may refer to different directories in shells conforming
10809 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10810 example, since the old example is now out of date.
10812 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10813 FOO" and "ls FOO" talk about different directories; this catches
10814 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10817 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10818 of rolling our own unset.
10819 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10820 in practice we needn't worry about CDPATH if unset doesn't work.
10822 * Makefile.in, aclocal.m4, bin/Makefile.in,
10823 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10824 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10825 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10826 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10827 tests/Makefile.in: Regenerate with Automake 1.6.3.
10829 * config/config.guess, config/config.sub, config/mkinstalldirs:
10832 * configure: Regenerate with self.
10834 2002-08-30 Kevin Ryde <user42@zip.com.au>
10836 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10839 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10841 * bin/autom4te.in (Request::load): Correctly test for "do" read
10844 2002-08-29 Akim Demaille <akim@epita.fr>
10846 * lib/Autom4te/General.pm (&xqx): New.
10847 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10848 hand, which is not portable.
10850 * bin/autom4te.in: Use them.
10851 Use &error instead of die.
10852 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10855 2002-08-17 Paul Eggert <eggert@twinsun.com>
10857 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10858 default list of compilers to try, since it was long ago superseded
10859 by the ksh fc builtin. Suggested by Steven G. Johnson.
10861 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10863 * doc/autoconf.texi (Invoking autom4te): End the option table,
10864 fixing a bug introduced by the previous patch.
10865 (Limitations of Make): Add a 'target lookup' subentry in the
10866 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10868 2002-07-29 Mark D. Roth <roth@feep.net>
10870 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10871 options and use $AUTOM4TE_PATH.
10872 * doc/autoconf.texi: Remove documentation of autom4te
10873 --include-envvar and --site-macro-subdir options and document
10874 use of $AUTOM4TE_PATH.
10875 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10876 arguments from each language section.
10878 2002-07-29 Paul Eggert <eggert@twinsun.com>
10880 * doc/install.texi: Include copyright symbol in copyright notice.
10882 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10884 (AM_MAKEINFOFLAGS): New macro.
10885 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10886 * Makefile.am (INSTALL): Use the new macros.
10887 Use -o rather than --output, since "missing" does not grok --output.
10889 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10891 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10892 comments do not always work. Never trust the exit status of
10895 2002-07-24 Kevin Ryde <user42@zip.com.au>
10897 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10898 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10900 2002-07-23 Paul Eggert <eggert@twinsun.com>
10902 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10903 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10904 apparently treats PATH="nonexistent" as if it contained ".".
10905 Bug reported by Stefan `Sec' Zehl.
10907 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10909 * doc/autoconf.texi (Limitations of Make): Mention the special
10910 handling of the obj/ directory by BSD make.
10912 2002-07-20 Kevin Ryde <user42@zip.com.au>

10943 2002-07-18 Akim Demaille <akim@epita.fr>,
10944 Alexandre Duret-Lutz <duret_g@epita.fr>
10946 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
10947 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

10952 description of the tarname default.
10954 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
10956 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10957 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10958 latter was not run.
10960 2002-07-17 Akim Demaille <akim@epita.fr>
10962 * lib/Autom4te/General.pm (find_file): Browse the directories in
10963 the order they are given.
10965 2002-07-17 Akim Demaille <akim@epita.fr>
10967 * tests/wrapsh.as, tests/wrappl.as: Merge into...
10968 * tests/wrapper.as: this.
10969 * tests/Makefile.am, configure.ac: Adjust.
10971 2002-07-17 Mark D. Roth <roth@feep.net>
10973 * configure.ac: Add --enable-site-macro-dir option.
10974 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
10975 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
10976 --site-macro-subdir options.
10977 * bin/autoconf.in: Add --prepend-include option.
10978 * bin/autoheader.in: Add --prepend-include option.

10981 * bin/autoupdate.in: Add --prepend-include option.
10982 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
10983 macro directory, remove note that include path directories are
10984 used in reverse order, and document --prepend-include option.
10985 * lib/autom4te.in: Use --prepend-include instead of --include.
10986 * tests/wrapsh.in: Use --prepend-include instead of --include.

11175 This improves on an earlier suggestion by H. Peter Anvin.
11177 2002-05-16 Paul Eggert <eggert@twinsun.com>
11179 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11180 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11181 Both macros now accept an optional source-dir arg.
11182 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11184 * NEWS: Document this.
11185 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11187 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11188 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11189 not for GNU extensions; this undoes part of the 2000-11-03 change,
11190 reverting to 2.13-compatible behavior.

11196 2002-05-08 Paul Eggert <eggert@twinsun.com>
11198 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11199 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11200 and it causes a 'test' syntax error if it fails.
11201 Bug reported by Stephen Gildea.
11203 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11204 If prototypes are supported, use them to check this at compile-time,
11205 instead of trying to check it at run-time. If we must do a run-time
11206 check, assume that setvbuf is standard when cross-compiling, as
11207 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11208 Bug reported by Paul D. Smith.
11210 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11211 argument specifying location of getloadavg.c. This removes a
11212 FIXME. This idea was taken from Jim Meyering's implementation in
11214 * doc/autoconf.texi (Particular Functions): Document this.
11215 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11216 that's what the code does; this fixes a bug reported by

11221 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11222 autopoint instead of gettextize.
11223 ($uses_alocal): Rename as...
11224 ($uses_aclocal): this.
11225 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11226 Suggested by Bruno Haible.
11228 2002-05-03 Akim Demaille <akim@epita.fr>
11230 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
11232 2002-04-29 Paul Eggert <eggert@twinsun.com>
11234 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11235 files to be 1 second older; just set them to be the same time.
11236 Also, sleep 1 second after the first aclocal, to work around
11237 problems with sub-second time stamps on the input files.
11239 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11241 * doc/autoconf.texi: Mention "set -e -x" lossage
11242 under node "Limitations of Builtins".

11248 From Christian Cornelssen.
11250 2002-04-29 Akim Demaille <akim@epita.fr>
11252 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11253 of lack of $LINENO support, then the test will compare the $LINENO
11254 in testsuite vs. the lineno in the test file. This is wrong, of
11256 Be sure to protect it.
11257 Reported by Patrick Welche.
11259 2002-04-25 Akim Demaille <akim@epita.fr>
11261 * doc/autoconf.texi (Obsolete Macros): Typo.
11262 Reported by Vladimir Volovich.
11264 2002-04-25 Akim Demaille <akim@epita.fr>
11266 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11267 than some of the input files, hence, on the second run of aclocal,
11268 if some of its input are younger, make them older.
11269 Suggested by Paul Eggert.
11271 2002-04-25 Akim Demaille <akim@epita.fr>
11273 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

11279 and ac_subst_vars be sh variables containing the list of
11280 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11282 (_AC_INIT_PREPARE): Use them to log them.
11283 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11284 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11285 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11286 _AC_SUBST_FILES and _AC_SUBST_VARS.
11287 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11289 2002-04-24 Akim Demaille <akim@epita.fr>
11291 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11292 autoheader, so that automake does not complain about a missing
11293 config.h.in that was to be created.
11295 2002-04-23 Akim Demaille <akim@epita.fr>

11351 importantly, this makes sure that the copyright notices appear in

11481 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
11482 (_AC_COMPILER_OBJEXT): Use them.
11483 Fixes Debian #138666.
11485 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
11487 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
11489 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
11490 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
11491 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
11492 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
11493 (AC_C_CONST): Same.

11507 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11508 to avoid versions of HP C which don't allow that.
11510 2002-03-27 Paul Eggert <eggert@twinsun.com>

11524 2002-03-25 Paul Eggert <eggert@twinsun.com>
11526 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11527 as POSIX requires, as it doesn't work with Zsh.
11528 * doc/autoconf.texi (Assignments): Document the problem.
11530 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

11541 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11542 when reinvoking the shell, to work around problems with installers
11543 who put strange things like "cd" commands in their environments.

11568 (Limitations of Usual Tools): Add mkdir section.
11570 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11571 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11572 back on AS_DIRNAME to compute prefixes otherwise; this is
11573 roughly what mkinstalldirs does. That way, we need not have
11574 our own filename disassembler. The old disassembler did not
11575 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11577 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11578 Create at_test_all by a series of assignments,
11579 not by a single assignment of a long string. The latter causes ksh
11580 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11581 presumably because of a buffer overrun.
11583 2002-03-14 Paul Eggert <eggert@twinsun.com>
11585 * lib/autotest/general.m4 (at_times_skip):
11586 Renamed from at_times. Now a boolean.
11587 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11588 says 'times: not found'.

11592 * bin/autoreconf.in (&study_gettextize): New.
11593 (&autoreconf): Handle newest gettextize.

11617 2002-03-11 Andreas Schwab <schwab@suse.de>

11620 does not do it if --with-lispdir is given.

11631 2002-03-08 Akim Demaille <akim@epita.fr>
11633 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11635 2002-03-08 Akim Demaille <akim@epita.fr>
11637 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11638 aliases the actual variables, and modifications of the former
11641 2002-03-08 Akim Demaille <akim@epita.fr>
11643 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11644 because of C-c: have m4 output in tmp files, then mv them.

11667 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11668 * lib/autoconf/general.m4 (AC_INIT): More informative error
11669 message for LIBOBJ.
11671 2002-03-04 Akim Demaille <akim@epita.fr>

11676 2002-03-04 Akim Demaille <akim@epita.fr>
11678 * doc/autoconf.texi (Transforming Names): Equality between target
11679 and host is irrelevant.
11680 (Specifying Names, Canonicalizing): Remove all references to the
11681 backward compatibility hooks. Rather, collect them all into...
11682 (Hosts and Cross-Compilation): this new section.
11683 * doc/install.texi (System Type): Ditto.
11684 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11685 that `--host' implies cross-compilation.
11687 2002-03-04 Akim Demaille <akim@epita.fr>
11689 * doc/autoconf.texi (Evaluation Macros): New.
11690 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11692 (_m4_foreach): Define the variant with immediate evaluation so
11693 that it contains exactly the items, not an expression which
11694 evaluation is the current item.
11695 (m4_re_string, m4_re_word): Don't over quote them.
11697 2002-03-04 Akim Demaille <akim@epita.fr>
11699 Instead of having stacking `shift's evaluated at the end, let
11700 `foreach' loops immediately evaluate them.
11702 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11703 $*. This is the n-th time I change my mind, but hopefully this is
11706 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11708 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11709 it was only a hack for m4_text_wrap.
11710 (m4_car2): Remove, replaced by...
11712 (_m4_foreach): Adjust.
11713 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11714 m4_bpatsubst for clarification.

11805 2002-02-05 Akim Demaille <akim@epita.fr>
11807 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

11830 optional are the sum of the previous files on the command line'.
11831 Also, pass `--reload-state=' on them, so...
11832 (handle_m4): don't.

11834 (M4sh): Rely on M4sugar.

11872 2002-01-28 Akim Demaille <akim@epita.fr>
11874 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11875 AUTOTEST_PATH *after* it was set.
11876 Don't put `.' in the PATH: the user should be precise and `./' if
11877 needed. In addition, given that the test suite does some `cd', if
11878 `.' is in the path, the `tested programs' sections will report
11879 programs found in the test suite's directory, while during the
11880 tests (performed in their own directory), these programs are no
11881 longer visible. In other words, the results is confusing and

11958 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11959 and PACKAGE_BUGREPORT from here...
11960 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11962 (_AC_INIT_PREPARE): AC_DEFINE these symbols.

11985 * doc/autoconf.texi (New Macros): Tweak wording.
11987 2001-12-14 Akim Demaille <akim@epita.fr>
11989 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11990 trailing files, don't apply `-rf' to files which might not be
11991 created by configure (core, core.*, and *.core), but just `rm -f'.
11992 Suggested by Jonathan Kamens.
11994 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11996 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11998 2001-12-14 Akim Demaille <akim@epita.fr>
12000 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
12002 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
12004 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
12005 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
12006 abs_srcdir, top_srcpath to abs_top_srcdir.
12007 (_AC_OUTPUT_FILES): Adjust.
12008 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
12009 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
12010 * tests/wrappl.in, tests/wrapsh.in: Adjust.
12012 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
12014 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
12015 C/Fortran linking on HP/UX, by extracting the Fortran library
12016 search path from the LPATH line in the $F77 -v output.
12018 2001-12-12 Kevin Ryde <user42@zip.com.au>
12020 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12021 forbidden file descriptors table.
12023 2001-11-26 Akim Demaille <akim@epita.fr>
12025 * bin/autoscan.in (%c_keywords): Build it at top level.
12026 Map to 1 in order to simplify its uses.
12028 2001-11-26 Akim Demaille <akim@epita.fr>
12030 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12031 Remove $filepath, useless.
12032 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12033 variables, they are really part of the tokens.
12034 Split the input line on spaces and then look for tokens.
12035 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12036 because of `lex$U.$(OBJEXT)'.
12037 (&scan_files): Use "@list" instead of join.
12038 * doc/Makefile.am (CLEANFILES): Add *.fns.
12040 2001-11-26 Akim Demaille <akim@epita.fr>
12042 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
12043 Remove, replaced by...
12044 * tests/wrappl.in: Be common for all the Perl executables.
12045 In particular autoscan and autoheader want -I.
12046 * configure.ac: Adjust.
12047 * lib/autoscan/headers: errno.h is portable.
12049 2001-11-26 Akim Demaille <akim@epita.fr>
12051 * bin/autoscan.in (used): New.
12054 2001-11-26 Akim Demaille <akim@epita.fr>
12056 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12058 (&scan_sh_file): Remove a duplicate pattern.
12059 (&check_configure_ac): Use long options.
12060 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
12062 2001-11-26 Akim Demaille <akim@epita.fr>
12064 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
12065 Before, having a line containing the opening of a multi line
12066 comment made the whole line be ignored.
12068 2001-11-26 Akim Demaille <akim@epita.fr>
12070 * doc/autoconf.texi (Using an Autotest Test Suite): New.
12071 (testsuite Scripts): Be one of its subsection.
12072 (Autotest Logs): New.
12074 2001-11-26 Akim Demaille <akim@epita.fr>
12076 Test groups are now run two directories deeper.
12078 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12079 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12081 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12082 top_srcdir, builddir and top_builddir.
12083 Use `at_*dir' relatively to the directory containing the
12084 suite, use `*dir' when relatively to the current group dir.
12086 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12088 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12089 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12090 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12093 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12095 * doc/autoconf.texi (Using System Type): Add an example of `case
12096 $host' usage so people quit using `case $target' everywhere.
12098 2001-11-22 Akim Demaille <akim@epita.fr>
12100 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12101 spotted by Jim Meyering.
12103 2001-11-16 Paul Eggert <eggert@twinsun.com>
12105 This patch implements a `long double' suggestion by Oliver Kiddle.
12107 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12108 static, to catch errors if the value isn't known at compile-time
12109 and the compiler supports dynamic arrays. Change its name from
12110 `_array_' to `test_array' to avoid potential name clashes.
12111 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12112 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12113 better than double. Catch a bug in GCC 2.95.2 x86.
12114 * doc/autoconf.texi (C Compiler): Document the above.
12117 2001-11-13 Akim Demaille <akim@epita.fr>
12119 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12121 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12123 2001-11-13 Akim Demaille <akim@epita.fr>
12125 * lib/autotest/general.m4 (AT_INIT): After having run the test
12126 group, go back to the initial directory, not to at_suite_dir.
12128 2001-11-13 Akim Demaille <akim@epita.fr>
12130 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12131 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12132 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12134 (AT_CHECK_CONFIGURE): Use absolute paths.
12135 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12136 The problem is still the old one: there is no means in M4 (that I
12137 know about) to create a defining macro, because there is no means
12138 to create `$1' etc., therefore, the defining macro ``swallows''
12139 all the arguments meant to the defined macro.
12141 2001-11-13 Akim Demaille <akim@epita.fr>
12143 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12144 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12146 * tests/aclocal.m4: Remove, as it is no longer used.
12148 2001-11-13 Akim Demaille <akim@epita.fr>
12150 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12151 variable names when referring to a single test group, or to
12152 `suite' when referring to the whole test suite.
12153 `at_last_test' is removed: m4 compute at_format itself.
12154 (at_stdout, at_stder1, at_stderr): New variables.
12155 (AT_CHECK): Use them.
12157 2001-11-13 Akim Demaille <akim@epita.fr>
12159 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12161 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12162 Do it as soon as a test fails, don't wait till the end of the test
12164 Don't remove $as_me.[0-9]*, since these files no longer exist.
12166 2001-11-13 Akim Demaille <akim@epita.fr>
12168 * tests/tools.at: Use absolute paths, since we are no longer run
12171 2001-11-13 Akim Demaille <akim@epita.fr>
12173 Now that tests are running in their own private dir, there is no
12174 need to list the files to remove at the end of tests groups.
12176 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12177 (AT_data_files, at_data_files): Remove.
12178 (AT_CLEANUP, AT_DATA): Simplify.
12180 Remove the group dir if !debug && !failed.
12181 * tests/atspecific.m4: Adjust.
12183 2001-11-13 Akim Demaille <akim@epita.fr>
12185 Start a new layout for Autotest: `testsuite' creates
12186 `testsuite.dir' in which the at-check-line etc. files are to be
12187 found, and `testsuite.dir/003' where the test group 3 is run.
12189 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12190 at_check_line_file, at_format, at_test_normalized, at_group_dir
12192 Create the directories.
12193 Use absolute paths for at- files.
12194 (AT_CHECK): Adjust.
12196 2001-11-11 Michael Matz <matz@kde.org>
12198 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12200 (m4_car): Properly quote arguments.
12202 2001-11-13 Akim Demaille <akim@epita.fr>
12204 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12205 with stricter rules on LIBOBJS.
12207 2001-11-12 Paul Eggert <eggert@twinsun.com>
12209 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12210 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12213 2001-11-12 Akim Demaille <akim@epita.fr>
12215 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12217 2001-11-12 Akim Demaille <akim@epita.fr>
12219 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
12220 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12221 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12222 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12223 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12224 specify to what the macro should be defined (typically to 1).
12226 2001-11-12 Akim Demaille <akim@epita.fr>
12228 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12231 2001-11-12 Akim Demaille <akim@epita.fr>
12233 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12234 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12235 definition used by Automake where LEX is +/- "${missing} lex" and
12236 `missing' itself contains variables.
12238 2001-11-12 Akim Demaille <akim@epita.fr>
12240 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12241 Now that M4sh pushes BODY, the comments were output at the end of
12244 2001-11-08 Akim Demaille <akim@epita.fr>
12246 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12247 that we can trace macros from aclocal.m4.
12248 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12249 obsoleted, and redirect to the former anyway.
12250 Reported by Ralf Corsepius.
12252 2001-11-08 Akim Demaille <akim@epita.fr>
12254 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12255 processed only if present.
12256 * tests/torture.at (Configuring subdirectories): Use autoreconf
12257 instead of successive calls to autoconf.
12258 Add a nonexistent subdirectory to exercise the patch above.
12259 Reported by Ralf Corsepius.
12261 2001-11-08 Kevin Ryde <user42@zip.com.au>
12263 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12264 doesn't accept .S files.
12266 2001-11-07 Akim Demaille <akim@epita.fr>
12268 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
12269 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
12270 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
12271 * bin/autom4te.in (warn_forbidden): New.
12272 (handle_output): Use it.
12273 Read m4_pattern_forbid with messages.
12275 2001-11-05 Akim Demaille <akim@epita.fr>
12277 * bin/autom4te.in (--normalize): Remove.
12278 * lib/autom4te.in: Adjust.
12280 2001-11-05 Akim Demaille <akim@epita.fr>
12282 * tests/Makefile.am (testsuite): Rename this target as...
12283 ($(TESTSUITE)): this.
12286 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12288 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12289 the --prefix option, also remove it's argument.
12291 2001-11-05 Akim Demaille <akim@epita.fr>
12293 * doc/autoconf.texi (testsuite Invocation): Update.
12294 (Writing testsuite.at): Update.
12296 2001-11-03 Akim Demaille <akim@epita.fr>
12298 * doc/autoconf.texi: s/@code/@command/ where appropriate.
12300 2001-11-03 Akim Demaille <akim@epita.fr>
12302 * lib/Autom4te/General.pm: (&catfile, &canonfile)
12303 (&file_name_is_absolute): New, wrappers around routines from
12305 Use and export them.
12306 (&find_configure_ac): Optionally take a directory where to look at.
12307 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12309 Default @ARGV to `.', not find_configure_ac.
12310 (&autoreconf): Argument is a directory.
12311 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
12312 * doc/autoconf.texi (autoreconf Invocation): Update.
12314 2001-11-03 Akim Demaille <akim@epita.fr>
12316 * lib/Autom4te/General.pm (@export_vars, @export_subs)
12317 (@export_forward_subs): New.
12318 Add basename, dirname, and fileparse.
12320 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
12321 Don't look for aclocal flags if we already know aclocal is not
12323 Move aclocal.m4t only if it exists.
12324 Reported by Ezra Peisach.
12326 2001-11-03 Akim Demaille <akim@epita.fr>
12328 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12329 passed on command line, defaulting to ./configure.ac if present.
12330 (&maybe_autoreconf, File::Find): Remove, unused.
12331 (&autoreconf): If autoconf is not used, don't try to trace.
12333 2001-11-02 Akim Demaille <akim@epita.fr>
12335 * configure.ac: Bump to 2.52g.
12337 2001-11-02 Akim Demaille <akim@epita.fr>
12341 2001-11-02 Akim Demaille <akim@epita.fr>
12343 * config/config.guess, config/config.sub, doc/standards.texi:
12344 * config/lispdir.m4: Update from masters.
12345 * configure.ac: Bump to 2.52f.
12347 2001-11-02 Akim Demaille <akim@epita.fr>
12349 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
12350 Don't run aclocal when aclocal.m4 is not from aclocal.
12352 Don't run libtoolize and gettextize if --install is not given.
12354 2001-11-01 Paul Eggert <eggert@twinsun.com>
12356 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
12357 be invoked before _AS_LINENO_PREPARE.
12358 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
12359 than character ranges.
12361 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
12362 invoking AS_BASENAME. Set the locale variables to 'C' if
12363 possible, as POSIX requires this to get the traditional
12365 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12367 2001-10-31 Paul Eggert <eggert@twinsun.com>
12369 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12370 with {}, as that triggers a bug in Bash 2.05.
12372 (_AS_LINENO_PREPARE): Use Sed rather than
12373 Awk. Fix the sed prepass to work even if there are multiple
12374 instances of $LINENO on the same line. Do not substitute for
12375 other variables like $LINENOT. Do not check file dates; such a
12376 check is unreliable on sufficiently fast machines, and removing
12377 the check makes the code simpler and more reliable. Check for
12378 output and chmod failures.
12380 * doc/autoconf.texi (Special Shell Variables): Document
12383 2001-10-31 Akim Demaille <akim@epita.fr>
12385 * tests/Makefile.am (atconfig): Remove this target, Automake
12388 2001-10-31 Akim Demaille <akim@epita.fr>
12390 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12391 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
12392 provided, while it is optional.
12393 * configure.ac: Adjust.
12395 2001-10-26 Paul Eggert <eggert@twinsun.com>
12397 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12398 lib/Autom4te/Struct.pm:
12399 Require Perl 5.005_03 instead of just 5.005, as some tests fail
12402 * doc/autoconf.texi (Special Shell Variables): Document some
12403 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
12405 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
12406 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
12407 eval $LINENO is not portable in practice.
12409 2001-10-24 Akim Demaille <akim@epita.fr>
12411 * lib/Autom4te/General.pm (backname): New.
12413 2001-10-24 Akim Demaille <akim@epita.fr>
12415 * m4/: Remove, merged into...
12418 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
12420 * doc/autoconf.texi (Shellology): Mention the problems with bash
12421 2.05's use of ANSI quoting in its `set' builtin.
12423 2001-10-22 Paul Eggert <eggert@twinsun.com>
12425 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
12426 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12427 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12428 POSIX decided to standardize on the int flavor of strerror_r.
12429 Always do char* test, as there's no reason not to.
12430 Assign to a char* var, to catch strerror_r that returns int*.
12432 * doc/autoconf.texi (Particular Functions):
12433 Document the above changes. Also, document the fact that
12434 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
12436 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
12438 2001-10-20 Akim Demaille <akim@epita.fr>
12440 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
12441 the executable was missing from the log.
12443 2001-10-20 Akim Demaille <akim@epita.fr>
12445 * lib/Autom4te/General.pm (&update_file): If destination is
12446 unchanged, remove the source.
12447 (&up_to_date_p): Don't be verbose, be debug.
12448 * bin/autoreconf.in: No longer support --m4dir.
12449 (&autoreconf): Display the full path of the configure.ac we are
12451 Trace it only once.
12452 Be sure to honor --force with gettextize.
12453 Always run aclocal.
12454 * doc/autoconf.texi: Adjust.
12456 2001-10-20 Akim Demaille <akim@epita.fr>
12458 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12460 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12461 `intl' is already present, as it refuses unless --force.
12462 (&parse_args): Use -I, --include instead of the old Autoconf
12464 ($localdir, $autoconf_dir): Remove.
12466 (&maybe_autoreconf): New, to preserve $_ for File::Find.
12468 2001-10-19 Jens Petersen <petersen@redhat.com>
12470 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

12938 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12939 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12941 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12943 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12944 * bin/autoupdate.in: Ditto.
12945 * bin/autoheader.in: Reworded a few comments.
12946 * bin/autoconf.in: Reworded help text for a few options.
12947 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,

12950 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12952 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12953 already have $file). Set output files to binary mode (helps avoid
12954 CR issues on DOSish systems).
12956 2001-09-19 Akim Demaille <akim@epita.fr>
12958 * lib/autotest/general.m4: Englishoes.
12959 From Tim Van Holder and Alexey Mahotkin.
12961 2001-09-18 Paul Eggert <eggert@twinsun.com>
12963 * doc/autoconf.texi (Common Shell Constructs): New node,
12964 documenting AS_DIRNAME.
12965 (Limitations of Usual Tools): Refer to it when discussing dirname.
12966 Also, update discussion of POSIX standard to reflect latest draft.
12968 * lib/autoconf/c.m4:
12969 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12971 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12972 Do not pass a first argument with leading '-'
12973 to expr, by parenthesizing initial integers that might be negative.
12975 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12976 now merely checks whether it is an error to pass an argument
12979 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12980 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12981 whether it is a (compile-time) error to pass an argument to
12982 getpgrp. This simpler test supports the revised documentation,
12983 and is all that AC_FUNC_GETPGRP's users really need.
12985 2001-09-18 Akim Demaille <akim@epita.fr>
12987 * doc/autoconf.texi (Limitations of Make) <$<>: New.

12995 2001-09-18 Paul Wagland <paul@wagland.net>
12997 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12999 Add test for AS_BASENAME.
13000 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
13001 added test. It now correctly handles /1/2/3/, returning '3' not ''.
13002 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
13003 * tests/base.at: Fixed the expected responses. The old ones were
13005 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
13006 the documentation claims it should (and how it behaved in 2.13).
13008 2001-09-18 Akim Demaille <akim@epita.fr>
13010 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13011 the AC_CONFIG_COMMANDS invocation.
13012 This also solves the name clash problems.
13013 Don't set the package's ID.
13014 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13015 No longer to be shipped.
13016 (version.in): Remove.
13017 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
13018 * lib/autoconf/status.m4: Adjust.
13019 Use `m4_PACKAGE_STRING'.
13020 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13021 the only optional argument is the name of the test suite.
13022 Expect `package.m4' to define the package signature.
13023 * lib/autom4te.in (Autotest): Add `package.m4?'.
13024 * tests/Makefile.am (package.m4): New.
13025 * tests/suite.at: ifnames is a victim.
13027 2001-09-18 Akim Demaille <akim@epita.fr>

13030 AC_LIBSOURCE, AC_CONFIG_FILES.
13031 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13032 program version string doesn't match the package's.
13033 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
13036 2001-09-17 Paul Eggert <eggert@twinsun.com>
13038 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13039 Allow expression to return any value that can fit into unsigned long
13040 (not int, as before). Check for output errors.
13042 2001-09-17 Bruno Haible <haible@ilog.fr>
13044 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13045 Always include <stdio.h> and <stdlib.h>. Evaluate
13046 the expression in an extra function before these includes. Call
13047 fprintf "%d" only after ensuring the argument is of type 'int'.
13048 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13050 2001-09-17 Paul Eggert <eggert@twinsun.com>
13052 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13053 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13054 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13055 when they don't exist.
13057 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13058 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13061 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13062 version with the version used by fileutils 4.1, except use
13063 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13066 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13068 2001-09-13 Akim Demaille <akim@epita.fr>

13108 * lib/autotest/general.m4 (AT_INIT): Create and remove
13109 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
13110 test suites can cohabit.

13114 * tests/mktests.sh: Don't output banners for empty test files.

13220 2001-09-05 Akim Demaille <akim@epita.fr>
13222 Be ready to handle filenames as stupid as `dnl.at', for if even
13223 the maintainer is dumb enough to do that...
13225 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13226 excellence in M4 quotation: consider `__file__' is active.
13228 And BTW, when invoking m4, pass the --include in the right order:

13403 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

13905 2001-08-15 Akim Demaille <akim@epita.fr>

13908 (&handle_m4): Use it.
13909 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

13989 magic values from an object file when cross-compiling.
13990 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13992 2001-08-10 Akim Demaille <akim@epita.fr>
13994 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13996 Suggested by Russ Allbery.
13998 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
14000 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
14001 current $prefix to the sub-configures.
14003 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
14005 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
14006 extension (needed on BeOS). Reported by Guido van Rossum.
14008 2001-08-09 Akim Demaille <akim@epita.fr>
14010 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14012 2001-08-07 Akim Demaille <akim@epita.fr>
14014 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14016 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14017 No need to remove the files before and after the each test, before
14018 each test and at the end of the suite is enough.
14019 Display only the children `times', not the shell's.
14020 If the test failed or was skipped, at-times is not available.
14022 2001-08-07 Akim Demaille <akim@epita.fr>
14024 Always produce testsuite.log, including when there are no
14025 failures. This helps getting information on skipped tests, and
14026 duration of the tests. Err, implement the latter btw.
14028 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14029 Dump information on the first run of each test.
14030 (AT_CLEANUP): Create `at-times' containing the duration of the
14033 2001-08-07 Akim Demaille <akim@epita.fr>
14035 The use of `dumpstat' revealed that `len' was used although it
14036 should not. m4_text_wrap was using it, but in the Autoconf world
14037 where it is legal. Hence (i) test M4sh in its own world, not
14038 Autoconf's, and (ii), ahem, fix the bug :)
14040 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14041 does not like `' instead of [].
14042 (AT_INIT): Forbid `^_?AT_'.
14043 And don't output such tokens.
14044 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14045 `script.as', and `autom4te.cache'.
14046 Remove `empty' and `macro' which are no longer used.
14047 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14048 * tests/m4sugar.at: Use it.
14049 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14051 2001-08-07 Akim Demaille <akim@epita.fr>
14053 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
14055 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
14057 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14059 2001-08-04 Akim Demaille <akim@epita.fr>
14061 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14062 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14064 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14065 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14066 (AC_F77_MAIN): Likewise.
14068 2001-08-04 Akim Demaille <akim@epita.fr>
14070 Don't rely on M4sugar outputting the patterns in files, since we
14071 might process the output _without_ running m4, hence without these
14074 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14075 * bin/autom4te.in (@Request::includes): Remove, unused.
14076 (@Request::source): Rename as...
14077 (@Request::input): this.
14078 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
14079 (&handle_output): Fetch the patterns from the traces.
14080 `$forbidden' and `$allowed' are constant: use m//o.
14081 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
14082 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14084 2001-08-04 Akim Demaille <akim@epita.fr>
14086 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14087 autoconf', i.e., in addition to caching traces, cache the output.
14089 * bin/autom4te.in (Request::cache): Rename as...
14090 (Request::id): this.
14091 ($cache, $icache, $tcache, $ocache): New.
14092 (&handle_m4): Save M4 output in the cache instead of $tmp.
14093 (&handle_output): Adjust.
14094 (&up_to_date_p): Check that the output cache is up to date too.
14095 (top level): Run `&handle_m4' iff force or the cache is invalid.
14096 Run `&handle_output' if the output cache is more recent.
14098 2001-08-04 Akim Demaille <akim@epita.fr>
14100 * bin/autom4te.in ($force): New.
14101 (&parse_args, &print_usage): -f, --force is a new option.
14102 (&handle_output): CPP directives might have spaces after `#'.
14103 (&parse_args): The first file only can be frozen.
14105 2001-08-04 Akim Demaille <akim@epita.fr>
14107 Don't let autom4te compute the `include' traces several times:
14108 first check that the trace cache file is up to date, and then
14109 compare its timestamp with that of the output.
14111 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14112 the preamble. Don't require 5.005 as Autom4te::General does it,
14113 and better yet (use `use', not `require'!).
14114 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14115 Class::Struct as Autom4te::Struct.
14116 * lib/Autom4te/General.pm (File::stat): Use it.
14117 (&mtime): New, export it.
14118 * bin/autom4te.in: Use it.
14119 Declare `$req' is invalid if it is outdated.
14120 Don't declare it valid before saving it if something went wrong.
14122 2001-08-04 Akim Demaille <akim@epita.fr>
14124 Autom4te shall not encode Autoconf data, and preselecting traces
14125 must be proposed to the users.
14127 * bin/autom4te.in (@required_trace): Remove.
14129 (&parse_args, &print_usage): -p, --preselect is a new option.
14130 (&up_to_date_p): Adjust.
14131 * bin/autoconf.in: Preselect some Autoconf macros.
14133 2001-08-04 Akim Demaille <akim@epita.fr>
14135 * tests/tools.at (autoconf --trace: user macros): Check traces on
14136 macros invoked without arguments, and macros invoked with multiple
14139 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

14144 2001-08-03 Akim Demaille <akim@epita.fr>
14146 * bin/autoconf.in ($@): Work around the usual sh bug.
14149 2001-08-03 Akim Demaille <akim@epita.fr>
14151 Clean up the handling of the M4 builtins tracing exception.
14153 * bin/autom4te.in (Request::request): Don't complete M4 builtins
14155 (@m4_builtins): Rename as...
14156 (@m4_builtin): this.
14157 (%m4_builtin_alternate_name): New.
14158 (&parse_args): Complete the trace requests with alternate names.

14164 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
14165 m4_if, and m4_wrap.
14167 2001-08-03 Akim Demaille <akim@epita.fr>
14169 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
14170 (m4_divert_pop): Dump the whole diversion stack when a diversion
14172 * bin/autom4te.in (&handle_output): Remember of the first
14173 occurrence of a possibly undefined macro, not the last.
14174 Complain about the possibly undefined macros in the same order as
14175 the appear in the output.
14176 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
14177 * tests/tools.at (autoconf: forbidden tokens, basic)
14178 (autoconf: forbidden tokens, exceptions): No longer sort
14179 autoconf's stderr, as it is now deterministic.
14180 Check that `dnl' is caught.
14182 2001-08-01 Akim Demaille <akim@epita.fr>
14184 * configure.ac: Bump to 2.52c.
14186 2001-08-01 Akim Demaille <akim@epita.fr>

14201 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
14202 `END', as `Autom4te::General::END' will be triggered.
14203 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
14204 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
14205 system to run `mv', `rm', and `cmp'.

14209 * lib/Autom4te/General.pm (&unique): New.
