1 2007-12-12 Eric Blake <ebb9@byu.net>
4 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6 (m4_require): Avoid extra macro calls.
8 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10 * tests/torture.at (srcdir): Fix quoting.
12 Do not pass top_srcdir to configure scripts in testsuite.
13 * tests/autotest.at (srcdir propagation): Copy install-sh to
15 (my only test): Drop setting of `top_srcdir'.
16 * tests/base.at (Input/Output): Likewise.
17 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
18 config.guess, and config.sub to test source tree.
19 Drop AC_CONFIG_AUX_DIR setting.
20 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
21 * tests/torture.at (Substitute a 2000-byte string): Drop
22 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
23 (Substitute a newline, datarootdir workaround): Likewise.
24 (Define a newline): Adjust for linenumber changes in configure.ac.
25 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
27 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
28 if `pwd` contains whitespace.
30 Quote $abs_top_srcdir in tests.
31 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
32 * tests/tools.at (Syntax of the shell scripts): Likewise.
34 * tests/m4sh.at (LINENO): Quote $0.
36 Fix testsuite program wrapper for whitespace in `pwd`.
37 The problem here is that the usual mantra is that command
38 variables can contain arguments, thus we cannot just escape
39 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
40 $top_builddir/tests directory early in $PATH, so that the
41 wrappers are found by their plain name.
42 * tests/wrapper.as: Put $testdir early in $PATH.
43 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
45 Proper config.status --file/--header and $srcdir escaping.
46 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
47 characters in $ac_file_inputs.
48 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
50 * tests/torture.at (datarootdir workaround): Adjust.
51 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
53 Fix Autotest for whitespace in `pwd`.
54 * lib/autotest/general.m4 (AT_INIT)
55 <at_func_create_debugging_script, Driver Loop>:
57 * tests/autotest.at (whitespace in absolute testdir): New test.
59 * lib/autom4te.in: Quote @datadir@.
61 Proper file name escaping in Autoconf programs and Perl modules.
62 This includes escaping of characters special to the shell
63 as well as special to Perl, e.g., leading `<' or `>'.
64 For example, when $file starts with `>', `open ">$file"'
65 wrongly tries to append to a different file.
66 * bin/autoconf.as: Fix quoting for autom4te options.
67 * lib/Autom4te/General.pm (shell_quote): New function, taken
68 from coreutils, written by Jim Meyering.
70 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
72 * bin/autoreconf.in (parse_args): Likewise.
73 * bin/autoscan.in (main): Likewise.
74 * bin/autoupdate.in (main): Likewise.
75 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
76 * bin/ifnames.in: Likewise, XFile usage fixes.
77 * tests/tools.at (autom4te and whitespace in file names): Extend
78 test. Test twice, with special characters allowed on w32, and the
79 rest. Test leading and trailing whitespace, for `open_quote'.
80 (autotools and whitespace in file names): New, analogous test.
81 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
82 by Russ Allbery and Eric Blake.
85 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
86 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
87 * lib/Autom4te/FileUtils.pm (open_quote): New function.
88 (update_file, contents): Use it.
90 * Makefile.am (autom4te-update): Rewrite for git.
92 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
94 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
97 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
98 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
100 2007-12-04 Eric Blake <ebb9@byu.net>
102 Manually resync with gnulib, since 'make cvs-update' no longer works.
103 * build-aux/config.guess: New upstream version.
104 * build-aux/config.sub: Likewise.
106 When using older automake, don't downgrade build-aux/texinfo.tex.
107 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
108 * doc/Makefile.am (TEXINFO_TEX): Add.
110 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
112 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
113 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
114 #undef as this runs afoul of our new way of creating config.h.
115 Problem reported by Jim Meyering in
116 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
118 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
120 Fix autom4te for unusual characters in input file names.
121 * bin/autom4te.in (files_to_options): Quote active characters
123 * tests/tools.at (autom4te and white space in file names):
126 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
127 Document that Tru64 awk always splits $0.
129 2007-11-24 Stepan Kasal <kasal@ucw.cz>
131 * lib/autotest/general.m4 (AT_INIT): Do not extract the
132 `#AT_STOP_...' line at the end of each test.
134 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
136 * lib/autotest/general.m4 (AT_INIT): For awk line number
137 extraction script, ensure `$at_group' has a defined value
138 even for the empty set, and properly quote its usage inside
141 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
143 * doc/autoconf.texi (Shell Functions): New chapter. Document
144 IRIX sh $0 issue in functions, move content from ...
145 (Portable Shell): ... here.
146 (Shell Script Compiler): Note that shell functions are not
147 totally unportable any more.
149 2007-11-22 Stepan Kasal <kasal@ucw.cz>
150 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
152 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
153 extracting the line numbers of the last needed test.
155 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
157 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
160 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
162 Fix IRIX testsuite debugging failures: $0 in functions.
163 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
164 Do not use $0 inside a function, as IRIX sh will set that to the
165 function name rather than the script invocation name.
167 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
168 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
170 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
171 to extract test scripts.
172 (AT_INIT): Extract and cache test script line numbers.
174 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
176 * lib/autotest/general.m4: Revert 2007-11-15 patch and
177 subsequent fixups; the awk -> here-document conversion trashes
178 performance too much with AIX sh.
180 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
182 * tests/local.at: Do not test m4, perl with AT_TESTED.
184 Diagnose and guard against write errors dealing with config.status.
185 The general idea is this: all write failures from `configure'
186 writing `config.status' are indicated by $ac_write_error, which
187 is only checked at the end. This is safe because config.status
188 code is not executed before the file is complete. Other write
189 failures, be they inside config.status, or in sub shell/awk
190 scripts spawned from configure or config.status, typically need
191 earlier checking, as their results are used right afterwards.
192 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
193 before writing config.status, check afterwards.
194 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
195 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
196 Set `ac_write_error' for write failures to config.status. Barf
197 upon write failures to temporary files.
198 Adjust note about closing and reopening the here-document.
199 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
200 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
201 reopening the here-document.
202 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
203 Ensure `ac_write_error' does not escape into config.status.
204 Also, add a couple of code paths not yet exercised in the test
205 suite: a config file with input from stdin, and a config header
207 Suggestion for catching write errors by Bruno Haible.
209 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
211 Avoid error with Tru64 awk and testsuite lines with many words.
212 * lib/autotest/general.m4 (AT_INIT): In the awk script that
213 reads the testsuite, set the field separator to an unusual value,
214 in order to not run over the limit of 199 fields. Tru64 4.0D awk
215 even splits the input if $i, i>0, was never accessed in the script.
217 Revert 2007-10-17 change.
218 * TODO: Multiline args in config files and headers mean something
219 different and are not fixed, see
220 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
221 Report by Stepan Kasal.
223 * doc/autoconf.texi (Generic Programs): Fix typo.
225 2007-11-16 Stepan Kasal <kasal@ucw.cz>
227 AC_*_TOOL does not canonicalize the prefix
228 * doc/autoconf.texi (Generic Programs): Do not say that
229 the *_TOOL macros canonicalize, they simply use the `host_alias'.
231 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
233 Diagnose write errors in config.status instantiations.
234 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
235 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
237 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
238 Extend test to also check for some write error failures, using...
239 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
240 Report by Bruno Haible.
243 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
245 (_AT_CHECK): Use less indentation, to save space.
247 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
249 Add witness macro for @top_build_prefix@ substitution.
250 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
251 (_AC_OUTPUT_FILE): Mention it here.
253 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
254 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
256 * lib/autotest/general.m4 (at_func_test): Remove.
257 (AT_INIT): Pre-extract test groups into separate files.
258 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
259 Remove at-test-source files together with the $at_group_dir.
260 * tests/autotest.at (Long test source lines): New test.
262 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
264 Shell functions and variables may share a namespace.
265 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
268 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
270 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
273 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
275 * lib/autoconf/status.m4: Fix a couple of comment typos.
277 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
279 2007-11-13 Jim Meyering <meyering@redhat.com>
281 Clean up the rule to create "expr".
282 * tests/Makefile.am (expr): Don't redirect directly to target.
283 Redirect just once, not for each echo statement.
284 Use $@, not literal "expr".
286 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
288 Don't worry about preprocessor when testing long long.
289 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
290 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
291 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
292 These no longer check for preprocessor flaws.
293 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
294 Do not check for preprocessor flaws.
296 2007-11-13 Jim Meyering <meyering@redhat.com>
298 Adapt dependencies, now that a version change doesn't modify configure.ac
299 * GNUmakefile: Remove "make clean" kludge.
300 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
302 Don't redirect directly to target.
303 Use $@, not literal "version.m4".
305 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
307 * doc/autoconf.texi (Making testsuite Scripts): Document
308 ":;{" shorthand as in previous patch.
310 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
312 * doc/autoconf.texi (Limitations of Builtins): Document problem
313 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
315 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
317 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
319 2007-11-12 Jim Meyering <meyering@redhat.com>
321 Add more non-srcdir build support.
322 * GNUmakefile (dummy): Split a long line.
323 Add -v option to autoreconf invocation.
325 Remove the autoreconf-provided INSTALL, so that we regenerate it.
326 * GNUmakefile (dummy): Remove INSTALL.
328 Remove racy commands to build scripts in bin/ and tests/.
329 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
330 are guaranteed to be built, remove the rules that tried to build
331 them. Before, with a parallel build, these rules could lead to
332 two processes writing tests/wrapper.in concurrently.
334 Build in man/ only *after* building in bin/ and tests/.
335 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
336 in both bin/ and tests/.
338 Accommodate non-srcdir build-from-checkout.
339 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
340 Use git's --git-dir=$srcdir/.git option.
341 Add quotes, in case tarball_version_file contains shell meta-characters.
342 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
343 * configure.ac: Pass "." to git-version-gen.
345 Avoid spurious test failures due to version skew.
346 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
348 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
350 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
351 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
352 Remove conftest.dSYM directory.
353 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
354 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
355 Remove `conftest.*' recursively.

357 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
359 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.

363 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
365 Fix typos in variable names.
366 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
368 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
370 Document that $((expression)) is not portable.
371 * doc/autoconf.texi (Shell Substitutions): Here.
373 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
375 Ignore configure --help* errors due to LINENO-impaired shells.
376 * tests/torture.at (Configuring subdirectories, Deep Package):
377 In the --help* tests in read-only trees, make `.' temporarily
378 writable again for the `stderr' file, and ignore errors due to
379 the attempt to write configure.lineno.
380 Report by Patrick Welche.
382 2007-11-10 Jim Meyering <meyering@redhat.com>
384 Generate package.m4 in build-dir, not srcdir.
385 * tests/Makefile.am (package.m4): Adjust target.
386 Don't redirect directly to $@.
387 (CLEANFILES): Add package.m4.
388 ($(TESTSUITE)): Depend on just-built package.m4, not the one
390 When running $(AUTOTEST), search "." before searching $(srcdir).
392 Avoid a race condition that would make parallel "distclean" fail.
393 * tests/Makefile.am (distclean-generic): Replace the default,
394 automake-provided rule with an identical one, but with an additional
395 dependency on distclean-local. Simply adding the dependency would
396 cause automake not to emit the rule at all.
397 * BUGS: Building with -jN works, now.
399 Distribute git-version-gen.
400 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
401 since GNUmakefile is distributed, and requires it for dist* rules.
403 Remove two more generated files from version control.
404 * INSTALL: Remove generated file.
405 * lib/autoscan/autoscan.list: Remove generated file.
407 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
409 * GNUmakefile (PATH): Remove stray apostrophes; they become
410 part of PATH, which isn't wanted here.
412 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
414 New config files output variable `top_build_prefix'.
415 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
417 * doc/autoconf.texi (Preset Output Variables): Document it.
419 Report by Bob Friesenhahn.
421 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
422 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
423 function, to parametrize arithmetic with expr vs. the shell.
424 Use it where possible.
425 Suggestion by Benoit Sigoure.
427 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
429 Adjust the documentation of autotest WRT atlocal.
430 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
431 when using Automake, to write a rule to produce atlocal, since it's
432 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
433 distributed, not atconfig.in.
435 2007-11-04 Eric Blake <ebb9@byu.net>
437 Update list information.
438 * README: Mention new autoconf-commit list.

453 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556

456 Adjust the build procedure so "make check" works reliably.
457 * README-hacking: Include an extra step between "make" and
458 "make check" to ensure that the latter passes.
460 Use just-built tools, when possible.
461 * GNUmakefile (PATH): Set and export here, ...
462 (dummy): ... rather than here.

518 Suggested by Paul Eggert.
520 2007-10-28 Jim Meyering <meyering@redhat.com>
522 * README-hacking: Autoconf, Automake, and Perl are required to build.

530 Suggestions from Ralf Wildenhues.
532 2007-10-28 Jim Meyering <meyering@redhat.com>
534 Make inter-release --version output more useful.
536 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
537 which indicates that it is built using the 19th change set
538 (in _some_ repository) following the "v2.61a" tag, and that 58dd
539 is a prefix of the commit SHA1.
540 * build-aux/git-version-gen: New file.
541 * configure.ac: Run it to set the version.
542 (AM_INIT_AUTOMAKE): Don't check NEWS here.
543 * Makefile.am (dist-hook): Arrange so that .version appears only
544 in distribution tarballs, never in a checked-out repository.
545 * .gitignore: Add .version here, too. Just in case.
546 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
547 not configure.ac, now that the version number changes automatically.
549 Ensure that $(VERSION) is up to date for dist-related targets.
550 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
551 git-version-gen doesn't match $(VERSION), but only for dist targets.

1849 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
1850 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former

1854 (AC_CHECK_SIZEOF): Allow argument to be a variable.
1855 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

2027 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
2028 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
2029 substitution will still be done by the special code.
2030 Report by Jim Meyering.
2032 * doc/autoconf.texi (File System Conventions): Mention that
2033 $PATH_SEPARATOR is for the build system only.
2034 Report by Keith Marshall.
2036 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2038 * doc/autoconf.texi (Setting Output Variables): Mention that
2039 all non-NUL characters are ok in substituted values.
2040 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
2041 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
2042 carriage return for $AWK, needed for BSD awk.
2043 * tests/torture.at (Substitute and define special characters):
2044 Test all 8 bit non-NUL characters.
2045 Report against Automake by Patrick Welche.
2047 2007-01-15 Stepan Kasal <kasal@ucw.cz>
2049 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
2051 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2053 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
2054 early on the reader side, drop stderr of the input to avoid
2055 `broken pipe' error output; this may happen even with shell
2056 builtin `echo' of some bash versions. Reports by Ian Macdonald
2057 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
2059 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2061 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
2062 separate items of `ac_user_opts', to avoid long lines.
2063 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
2065 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2067 * doc/autoconf.texi: Fix some typos.
2069 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
2071 Fix some wording problems noted by Paolo Bonzini in:
2072 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
2073 * doc/autoconf.texi (Signed Overflow Examples): Give more
2074 discussion about the allow_superuser_privileges example,
2075 and change it a bit to make things clearer.
2076 (Optimization and Wraparound): Clarify whether the compiler
2077 will generate an infinite loop for the example derived from
2078 Autoconf's mktime test.
2079 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
2080 Also, clarify unsigned multiplication overflow.
2082 2007-01-04 Eric Blake <ebb9@byu.net>
2084 * bin/Makefile.am (RELEASE_YEAR): New macro.
2085 (edit): Use it to supply correct copyright year to scripts.
2086 * bin/autoconf.as (version): Use it.
2087 * bin/autoheader.in ($version): Likewise.
2088 * bin/autom4te.in ($version): Likewise.
2089 * bin/autoreconf.in ($version): Likewise.
2090 * bin/autoscan.in ($version): Likewise.
2091 * bin/autoupdate.in ($version): Likewise.
2092 * bin/ifnames.in ($version): Likewise.
2094 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
2096 * doc/autoconf.texi (Integer Overflow): Revised based on today's
2097 feedback. The most important changes document what happens when
2098 you convert an out-of-range value to a signed integer type, and
2099 say that (sum < a) != (b < 0) reliably detects overflow when sum =
2102 * doc/autoconf.texi (Integer Overflow): Greatly expand and
2103 rewrite, taking notions from the recent discussion on the gcc and
2104 autoconf mailing lists; please see
2105 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
2106 and follow the many links.
2107 (Integer Overflow Basics, Signed Overflow Examples):
2108 (Optimization and Wraparound, Signed Overflow Advice):
2109 (Signed Integer Division): New sections.
2111 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
2113 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
2114 preprocessor macro arguments in traced name.
2115 * doc/autoconf.texi (Defining symbols): Document longstanding
2116 support for AC_DEFINE-ing macros with arguments, and document
2117 behavior when the same variable has multiple AC_DEFINEs.
2118 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
2119 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
2120 macros directly, giving much shorter and simpler code.
2122 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
2124 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
2125 space before "$ac_configure_args" to prevent a 'config.status
2126 --recheck' failure if ac_configure_args doesn't contain a leading
2127 space. This works around a problem with the XEmacs configure.ac,
2128 which uses the (undocumented) ac_configure_args variable
2129 inconsistently with Autoconf.
2131 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
2133 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
2134 Include <limits.h>, and use its INT_MAX to rewrite the
2135 j loop so that it does not overflow 'int'. Problem reported by
2137 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
2138 Play it safe by shifting left by 1 rather than multiplying by 2,
2139 as GCC is less likely to optimize this away when the value
2140 is signed (when it assumes overflow leads to undefined behavior).
2141 Also, don't assume time_t uses two's complement.
2143 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2145 * tests/torture.at (Substitute a 2000-byte string): Avoid using
2146 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
2147 dumps core on it. Report by Tim Rice.
2149 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2151 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
2152 --disable-option-checking to --help output even when
2153 AC_PRESERVE_HELP_ORDER is not used.
2154 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
2155 --with argument, rather than argument with [-.] replaced by
2157 * NEWS: Fix typo in previous change; the news was in the
2160 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
2162 * NEWS: Warnings are now generated by default for unknown
2163 --enable-* and --with-* options.
2164 * doc/autoconf.texi (Option Checking): Renamed from
2165 (Configure Option Checking). Tighten up the wording a bit.
2166 (External Software, Package Options): Cross-reference to Option
2167 Checking, and use this to shorten our section.
2168 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
2169 "$x" to test "x$foo" != x.
2170 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
2171 Don't warn if $enable_option_checking is "no".
2172 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
2173 ac_unrecognized_opts to the empty string.
2174 Don't echo the unrecognized opts, as this might mishandle
2175 backslashes or leading -.
2176 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
2177 usage next to the other --disable-FEATURE options in the
2180 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
2182 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
2183 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
2184 Print warning for unrecognized --with and --enable options
2185 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
2186 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
2187 Disable option checking when subdirs are configured.
2188 (AC_OUTPUT): If warnings are enabled, print warning about
2189 unrecognized --with and --enable options at the end of
2190 the configure output (as well as at the beginning).
2191 * doc/autoconf.texi (Option Checking): New node.
2192 Document new option warning functionality.
2194 2006-12-16 Eric Blake <ebb9@byu.net>
2196 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
2197 * NEWS: Start news for current version.
2199 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
2201 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2202 Define HAVE_GETMNTENT to 1, not to the empty string.
2203 Problem originally reported by Jochen Friedrich in
2204 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
2206 This change prompted by a problem report by Andrey Simonenko in
2207 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
2208 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
2209 object-like macros only, in the traditional portable character
2211 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
2212 Warn about attempts to define things that are not identifiers.
2213 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
2214 awful hack that AC_DEFINEd macro names containing parentheses.
2216 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
2218 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
2219 too drastic, even if Texinfo in theory requires it for info mode.
2221 (config.status Invocation): Renamed back from Recreating a
2223 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
2224 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
2226 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2228 * NEWS: Version 2.61a.
2230 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
2231 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2233 * NEWS: Document changes with echo and printf, and the lack
2234 of limits on the total size of multi-line values of substituted
2235 variables, and the AC_FUNC_FSEEKO fix.
2237 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
2239 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
2240 Writing configure.ac.
2241 (Autoconf Input Layout): Renamed from configure.ac Layout.
2242 (Recreating a Configuration): Renamed from config.status Invocation.
2243 (Obsolete Recreation): Renamed from Obsolete config.status Use.
2244 (acconfig Header): Renamed from acconfig.h.
2245 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
2246 (Writing Testsuites): Renamed from Writing testsuite.at.
2247 (Autom4te Cache): Renamed from autom4te.cache.
2249 * BUGS: Remove mention of VPATH problem, since it's now documented
2250 not to be a bug in the Autoconf build procedure itself, but rather
2251 a problem with the proprietary `make' programs.
2253 * doc/autoconf.texi (Build Directories): Add a cross reference
2256 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
2257 * doc/standards.texi: Sync from gnulib.
2259 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
2260 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
2261 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
2262 generated automatically.
2264 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
2266 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
2267 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
2268 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
2270 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2272 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
2273 `CEOF$ac_eof' special marker, the awk script cannot contain a
2274 line matching `^CEOF', so this is not needed any more.
2275 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
2276 special marker in the test.
2278 2006-12-06 Stepan Kasal <kasal@ucw.cz>
2280 * tests/tools.at (autom4te preselections): Use `find -newer';
2281 remove one of the sleeps.
2283 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
2284 more readable, using ...
2285 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
2287 * doc/autoconf.texi (autoheader Invocation): Do not double-
2288 quote the parameter of `AH_BOTTOM' in the example.
2290 2006-12-05 Stepan Kasal <kasal@ucw.cz>
2292 * doc/autoconf.texi (Configuration Headers): Remove the
2293 example with multiple input files.
2294 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
2295 multiple input files.
2297 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2299 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
2300 creating the awk substitution script, handle one input line at a
2301 time, so that the maximum length of a substituted (multi-line)
2302 value is not limited by the size of the sed pattern space.
2303 The trade-off is a slightly repetitive sed script.
2304 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
2305 can only have up to 7 characters, due to Solaris 10 /bin/sed.
2306 * tests/torture.at (Substitute a 2000-byte string): Increase the
2307 test with several long lines, they should not be caught by sed
2310 * tests/tools.at (autom4te preselections): New test, to flag
2311 entries missing from autom4te.cfg.
2312 Report by David Byron <dbyron@hheld.com>.
2314 * tests/torture.at (Substitute a 2000-byte string): Actually use
2315 AC_PROG_AWK, so the last change works as intended.
2316 (Substitute and define special characters): Likewise.
2317 (Substitute a newline): Likewise.
2319 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
2320 instead of `awk' consistently.
2321 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
2322 * tests/torture.at (Torturing config.status): Test both the
2323 result of AC_PROG_AWK and plain awk.
2324 (Substitute a 2000-byte string): Likewise.
2325 (Substitute and define special characters): Likewise.
2326 (Substitute a newline): Likewise.
2328 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
2330 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
2331 can be assigned to a function pointer. Problem reported by
2332 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
2333 part of a patch by Ralf Wildenhues in that same bug report.
2335 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
2337 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
2338 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
2340 2006-12-01 Eric Blake <ebb9@byu.net>
2342 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
2343 cross-compiling from cygwin to mingw.
2344 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
2345 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
2346 to lib/autoconf/c.m4.
2348 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2350 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
2351 string for more reliable failure. Wrap the entire test that
2352 causes the broken Solaris printf to dump core, in a subshell,
2353 so the segmentation fault message is reliably suppressed.
2354 Fix shell expansion errors by using /usr/ucb/echo always;
2355 avoid an error on systems without it by another subshell.
2356 Avoid m4 expansion of `$1'. Set the zeroth argument of the
2357 subshell-$as_echo to `as_echo', for better error message.
2359 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2361 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
2362 `BASH_SOURCE' contain a newline, set them to empty, as they may
2365 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
2367 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
2368 years and is too hard to maintain now. The last straw was
2369 reported by Jerker Baeck in
2370 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
2371 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
2372 * doc/autoconf.texi (Particular Functions): Move
2373 AC_FUNC_SETVBUF_REVERSED from here...
2374 (Obsolete Macros): ... to here. Say that it does nothing now.
2375 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
2376 Turn into (almost) a no-op.
2378 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
2380 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
2381 These macros are obsolescent and new applications shouldn't need them.
2382 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
2383 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
2384 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
2385 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2386 (AC_FUNC_VPRINTF): Likewise.
2387 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
2388 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
2389 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
2391 * doc/autoconf.texi (Setting Output Variables): Mention that
2392 @VAR1@VAR2 has unspecified behavior. Problem reported by
2394 * NEWS: Mention this.
2396 * Makefile.am: Put only a single '#' into the copyright notice,
2397 so that it's also present in the output file. Standardize wording
2398 in makefile copyright notices to match GNU coding standards.
2399 * bin/Makefile.am: Likewise.
2400 * doc/Makefile.am: Likewise.
2401 * lib/Makefile.am: Likewise.

2407 * man/Makefile.am: Likewise.
2408 * tests/Makefile.am: Likewise.
2409 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
2412 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2414 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
2415 in the sed script that mangles the awk script: delete up to the
2416 first exclamation mark only.
2417 * tests/torture.at (Substitute and define special characters):
2420 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2422 Rewrite config files generation: avoid quadratic growth in
2423 the number of substituted variables by using awk instead of sed
2424 for the bulk of the substitutions.
2425 * NEWS: Mention this.
2426 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
2427 forbidden in the output (and thus input) file.
2428 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
2429 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
2430 generate just one large awk script for substitutions,
2431 eliminating much of the earlier complexity, while adding some
2432 new complexity. Only expand the substitution templates at
2433 configure time, for smaller configure script size. If
2434 _AC_SUBST_FILES are used, test 'awk' for working getline support
2435 at config.status time. If absent, interpolate through the
2436 shell. The awk script was written with much help
2437 from Paolo Bonzini and Paul Eggert.
2438 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
2439 (_AC_SED_FRAG_NUM): Likewise.
2440 (_AC_SUBST_CMDS): Renamed from...
2441 (_AC_SED_CMDS): ...this.
2442 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
2443 * tests/torture.at (Substitute a 2000-byte string): Also
2444 substitute a line with 1000 words, and a variable with several
2446 (Substitute and define special characters): Test awk special
2447 characters, and put substitution input strings `@foo@' in the
2448 output, to test that no recursion happens; test several other
2449 combinations from Paolo Bonzini.
2451 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
2453 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
2454 that replaced echo with AS_ECHO where this wasn't necessary.
2455 Problem reportd by Ralf Wildenhues.
2456 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
2457 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
2458 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
2460 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2462 * lib/freeze.mk (GREP): Removed, no need to initialize this.
2464 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
2466 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
2467 that traditional Awk lacks 3-arg "split". It has it.
2468 Mention that FS must be a single character, and a few other
2469 99-byte limits of traditional Awk.
2470 Mention that if (i in a) doesn't work with traditional Awk.
2472 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
2474 * tests/autotest.at (BSx641-newline in command):
2475 (BS-BS-newline in command, BSx640-newline in command):
2476 (Newline-CODE-BS-newline in command):
2477 (Single-quote-BS-newline in command):
2478 (Single-quote-newline-BS-newline in command):
2479 Use printf '%s\n' instead of echo, for portability to hosts
2480 where echo interprets backslashes. This will break on hosts
2481 that lack printf, but for now let's assume all such hosts
2482 are dead (if not, we should get reports of test failures).
2484 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2486 'echo' has some portability problems, when given a first argument
2487 with a leading '-', or when given any argument containing '\'.
2488 Avoid using 'echo' in these cases.

2517 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

2539 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
2541 * configure.ac (AC_INIT): Bump to 2.61a.
2544 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
2548 * configure.ac (AC_INIT): Bump to 2.61.

2640 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
2643 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
2645 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
2646 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
2647 Imported from a similar patch to gnulib by Bruno Haible.

2668 and Stepan Kasal <kasal@ucw.cz>
2670 Handle special characters in test case titles correctly.

2673 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
2674 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
2675 argument. Extend to check titles printed by ./micro-suite and

2678 Single-quote in a test title,
2679 Double-quote in a test title): Don't expect failure anymore.
2680 (Backslash in a test title): Put a non-whitespace character after the
2681 backslash so that Bourne shells might actually see it as an escape
2683 (Brackets in a test title,
2684 Pound in a test title,

2691 Macro with backslash in a test title): New tests expected to fail.
2692 * tests/torture.at (#define header templates): M4-quote this title in
2693 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
2694 The visible effect was a stray [] in the testsuite output.
2696 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2698 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
2699 `trap ... 0' inside a function, for AIX sh.
2701 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
2703 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
2704 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
2705 5363) simply issues a warning when dividing by zero at compile
2706 time. Problem reported by Elias Pipping.
2708 2006-10-26 Eric Blake <ebb9@byu.net>
2711 * doc/autoconf.texi (Evaluation Macros): Improve the example to

2740 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
2741 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
2742 reported by Nelson H. F. Beebe for Coreutils 6.4.
2744 * tests/tools.at (autoconf --trace: user macros): Remove test
2745 for tracing multiline macros, since m4 1.4.7a uses a different
2746 way to number lines. Problem reported by Ralf Wildenhues.

2776 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
2777 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

2822 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
2824 (Imported from Automake.)
2825 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
2826 which incorrectly sets the mode of an existing destination
2827 directory. In some cases the unpatched install-sh could do the
2828 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
2829 system. We hope this is rare in practice, but it's clearly worth
2830 fixing. Problem reported by Alex Unleashed in
2831 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
2832 Also, don't bother to check for -m bugs unless we're using -m;

2879 2006-10-13 Stepan Kasal <kasal@ucw.cz>
2881 * doc/autoconf.texi (Autoheader Macros): Warn that the text
2882 added to the template can get mangled.
2884 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2886 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
2887 include the default headers, and redefine obstack_chunk_alloc

2912 Use a better substitute, by inspecting the output of "ls"
2913 rather than just using ":".
2914 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
2915 rather than AS_EXECUTABLE_P, since we needn't worry about
2916 non-regular files here.
2918 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
2919 due to configuration hassles with this. See Tonya Underwood's report

2947 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2948 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2950 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2951 with werror_flag and conftest.err and so forth. This is more
2952 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2953 and anyway the user shouldn't normally want to see this gorp logged.
2954 Problem reported by Ralf Wildenhues.
2955 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2956 empty, not 'no', since the rest of the code uses 'test -z'.

2964 Problem reported by mwoehlke in
2965 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2967 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2968 than creating a file to use with test -x; this is much faster.

3227 broken lex libraries like native ia64-hp-hpux11.22; see
3228 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

3395 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3397 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
3398 --help' should mention that `--version' outputs configuration
3399 settings. Report by Bruno Haible.
3401 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
3403 Fix test suite failures reported by Pierre in
3404 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
3405 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
3406 the compiler created a file "b.out" when it didn't create anything
3408 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
3409 Discard stderr too, when invoking the test script.
3411 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
3413 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
3414 in the restoring of the werror flag.
3416 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
3418 * doc/autoconf.texi (Volatile Objects): Be even a little
3419 less skeptical about "volatile", after discussion with
3420 Bruno Haible on bug-gnulib.
3421 (Limitations of Usual Tools): Warn about sed stripping
3422 leading white space from text. From Bruno Haible.
3424 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
3426 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
3427 compiler complains about it, even if things works after the
3428 complaint. Problem reported by Peter O'Gorman.
3430 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
3431 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
3432 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
3434 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3436 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
3437 after -R regardless of host. Patrick Welche reports that this
3438 fixes things on NetBSD 3.99.
3440 * NEWS: Recommend M4 1.4.5.
3442 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
3443 * tests/tools.at (autom4te cache): Update wording of diagnostic
3446 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3448 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
3449 under AC_C_VOLATILE.
3450 (Volatile Objects): Be a little less skeptical about what
3451 "volatile" means. Derived from thoughts by Ben Pfaff in
3452 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
3454 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3456 * doc/autoconf.texi: Fix some typos.
3458 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3460 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3461 more globally, since the 2006-06-30 patch didn't suffice. Problem
3462 reported by Keith Marshall. Also, don't bother with builddir2,
3463 since it shouldn't be needed any more.
3465 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
3467 * doc/autoconf.texi (Generic compiler characteristics):
3468 Document AC_COMPUTE_INT. Fix wrong statements on Default
3469 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
3471 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
3472 (_AC_COMPUTE_INT): Add obsoletion warnings.
3473 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
3476 * NEWS: Document change.
3478 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
3480 * doc/autoconf.texi (Volatile Objects): New section.
3482 * NEWS: Document previous change.
3484 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
3486 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
3487 Require that long long int be at least 64 bits wide. C99 requires
3488 this and enough programs depend on it so we should check for it.
3489 Bruno Haible reports in
3490 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
3491 that long long int is 32 bits wide with some nonstandard compilers.
3492 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
3494 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
3496 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
3497 to a nonexistent file, so that we don't have to worry about
3498 a local site configuration that doesn't use /usr/local.
3499 Problem reported by Keith Marshall in
3500 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
3502 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
3504 * doc/autoconf.texi: Be more consistent about using @acronym with
3505 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
3506 quite right (it talked about "OSF/Tru64", even though the
3507 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
3508 and it even mentioned "OSF 4"!) and at this point there's little
3509 reason to talk about OSF any more, since it died in 1994.
3510 (Specific Compiler Characteristics): Simplify example of
3511 negative-size array.
3512 (File Descriptors): Reorder to make the text flow better.
3513 Remove joke about "appreciate the various levels"; I didn't get it.
3514 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
3515 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
3516 (File Descriptors, Limitations of Usual Tools):
3517 Tone down the advice against renaming or removing open files.
3518 (Limitations of Usual Tools): Add a new section, on 'rm'.
3520 2006-06-26 Stepan Kasal <kasal@ucw.cz>
3522 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
3523 -lXt in LIBS, idea from Karsten Hopp; this was due since
3526 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3527 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3528 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3529 (which belong to Xt, not X itself). See Debian bug 327655.
3531 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3533 * configure.ac (AC_INIT): Bump to 2.60a.
3536 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3540 * configure.ac, NEWS: Update.
3542 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3544 * config/texinfo.tex: Sync from upstream.
3546 * bin/autom4te.in (handle_traces): Transform the `@S|@'
3547 quadrigraph correctly in traces.
3549 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
3552 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
3553 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
3555 * doc/autoconf.texi (Changed Directory Variables): New node,
3556 to document the whole `datarootdir' business a bit better.
3558 * tests/torture.at (datarootdir workaround): Extend test.
3559 Prompted by report by Alexandre Julliard.
3561 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
3563 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
3564 when using default mode of IBM C 6 for AIX. Problem and two-line
3565 fix reported by Larry Jones.
3567 2006-06-22 Alexandre Julliard <julliard@winehq.org>
3569 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
3570 about literal '${datarootdir}' if a definition is found in the
3573 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
3575 * NEWS: Use "M4" rather than "m4" when appropriate.
3576 Problem reported by Eric Blake.
3577 * doc/autoconf.texi: Likewise.
3578 Use @acronym around BSD, GCC, and GNU when appropriate.
3579 (Why GNU M4): Renamed from "Why GNU m4".
3580 (Redefined M4 Macros): Mention that Posix
3581 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
3582 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
3585 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3587 * bin/autom4te.in (handle_output): Do not forbid the empty
3589 * tests/tools.at (autoconf: the empty token): New test.
3591 2006-06-20 Stepan Kasal <kasal@ucw.cz>
3593 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
3594 calls, so that we do not care whether they are LIFO or FIFO;
3595 in the m4_wrap, do not check which diversion is the topmost
3596 one, just check that the stack is balanced at the end.
3597 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
3598 base diversion forever--pop the previous diversion before
3599 opening the new one; consequently, remove the m4_wrap call.
3600 * lib/autotest/general.m4 (AT_INIT): Likewise.
3601 * tests/m4sugar.at: Do not use
3602 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
3604 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
3605 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3607 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
3608 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
3609 Rework example of m4wrap token-pasting trouble so that it doesn't
3610 care whether it's LIFO or FIFO.
3611 Fix some "contrary to"s that are awkward in English.
3613 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3615 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
3616 to `yes' instead of `int$1_t' if the type is found, for more
3617 consistent configure output (where $1 is the number of bits).
3618 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
3619 Suggested by Bruno Haible.
3621 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
3622 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
3623 with system headers. Report by Bruno Haible.
3625 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3627 * config/config.guess, config/config.sub: Sync from upstream.
3629 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
3630 in order to avoid picking up an older installed frozen m4sh.m4f.
3631 Besides an outdated shell startup, this could have been created
3632 by an earlier M4 version with incompatible frozen file format.
3634 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
3636 * README: Recommend m4 1.4.4 instead of 1.4.3..
3637 * doc/autoconf.texi: Likewise.
3638 (Special Chars in Names): Say that $(.FOO) is portable, as
3639 suggested by Stepan Kasal.
3640 (Installation Directory Variables, Build Directories):
3641 (Automatic Remaking, Subdirectories, Fortran Compiler):
3642 (Making testsuite Scripts, Defining Directories):
3643 Quote variable usages better.
3644 (Making testsuite Scripts): Add clean-local rule to makefile
3645 snippet, by Eric Blake.
3646 (Installation Directory Variables): Fix table item font.
3647 Reword slightly to clarify. Generalize advice about
3648 not using special characters to include all file-related
3649 vars, not just VPATH.
3650 (Special Chars in Variables): Warn about special characters in
3652 (Assignments): Clarify default-value example as suggested by
3654 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
3655 (Special Shell Variables): Note leading ./ or ../, as suggested
3657 (Limitations of Builtins): Under cd, warn about CDPATH.
3658 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
3661 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3663 * doc/autoconf.texi (Configuration Actions): Remove duplicate
3664 `@var', for texi2html.
3665 (Systemology): Some more word wrapping, for DVI output.
3666 (autom4te Invocation): The short option for `--melt' is `-M',
3669 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
3671 * doc/autoconf.texi: More formatting and English tweaks,
3672 many suggested by Ralf Wildenhues.
3673 Reword to avoid "@code{...}'s" and the like, since it's ugly
3674 with Emacs info mode. discontents -> woes.
3675 Put a few "will"s back. time stamp -> timestamp.
3676 side-effect -> side effect.
3678 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
3680 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
3681 Warn about $@ not persisting. Problem reported by Julien Danjou in
3682 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
3683 (Special Chars in Names): Renamed from Leading _ in Macro Names.
3684 Mention other special chars, too.
3686 2006-06-14 Eric Blake <ebb9@byu.net>
3688 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
3690 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
3692 * doc/autoconf.texi: Some systematic minor improvements, as
3693 follows. Use "makefile" when talking about makefiles
3694 generally (which might be named "makefile" or "Makefile" or even
3695 "foo.mk"), "Makefile" when talking about a specific makefile
3696 called "Makefile". This unclutters the text from weird quotes
3697 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
3698 values" rather than "@var{foo}s" and similar constructs containing
3699 "}s". Use "Make rules" rather than "Makefile rules". Minor
3700 English-language improvements. Change the prefix "sub-" to "sub"
3702 Put blank lines around examples more consistently.
3703 Avoid "rather" and "very" as intensifiers.
3704 Avoid "will" as an auxiliary.
3705 (Limitations of Make): Split this node into....
3706 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
3707 (Leading _ in Macro Names, Backslash-Newline-Newline):
3708 (Backslash-Newline Comments, Long Lines in Makefiles):
3709 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
3710 (obj/ and Make, make -k Status, VPATH and Make):
3711 (VPATH and Double-colon, $< in Explicit Rules):
3712 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
3713 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
3714 New nodes, resulting from splitup of Limitations of Make.
3715 All cross-references changed. Raise the top node from
3716 a section to a chapter, and all subnodes accordingly.
3717 Redo the introductory wording to match the new organization.
3718 (Installation Directory Variables): Use an example that is
3719 closer to what Autoconf actually does. Mention that VPATH's
3720 value should not contain metacharacters or white space.
3721 (Fortran Compiler): Fix a VPATH bug in an example.
3722 (Leading _ in Macro Names): Mention that this problem is no longer
3723 of practical concern.
3724 (VPATH and Make): Reword the advice to make it clearer
3725 that Autoconf and Automake support VPATH in non-GNU make, but
3726 many packages have bugs in this area.
3727 ($< in Explicit Rules): Refer to Build Directories rather
3728 than using a (non-VPATH-safe) example.
3729 (Automatic Rule Rewriting): Mention the sort of disaster that
3730 can ensue with Solaris-style rule rewriting with VPATH.
3732 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3734 * doc/install.texi (Compilers and Options): Weaken the
3735 suggestion to use GNU make for VPATH builds.
3737 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
3738 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
3740 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
3741 in regular expression.
3743 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3745 * doc/autoconf.texi (Installation Directory Variables):
3746 Drop extra @samp from `@table @samp' item.
3747 (Limitations of Usual Tools): Comment fix.
3748 Do not nest @samp just to point to other table items.
3749 (Writing testsuite.at) <AT_CHECK>: The second argument to
3750 `@dvar' is already @samp'ed.
3751 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
3752 do not use @var in the second argument.
3754 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
3756 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
3757 $as_shell.exe too. Problem reported by Andreas Buening in
3758 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
3760 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3762 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
3763 `unused variable' compiler warning, for `-Wall -Werror'.
3764 Reported by Jaap Haitsma in
3765 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
3767 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
3769 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
3770 case the compiler dumps core. Problem reported for
3771 OpenServer 5.0.7 by Tim Rice in
3772 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
3773 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
3776 2006-06-06 Tim Rice <tim@multitalents.net>.
3778 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
3779 "ERROR" only shows up in "make check" output if there is an
3782 2006-06-06 Eric Blake <ebb9@byu.net>
3784 * tests/tools.at (automatically allowed tokens): Fix typo.

3788 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
3790 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1

3796 * configure.ac (AC_INIT): Bump to 2.59e.
3799 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3803 * config/texinfo.tex: Sync from upstream.
3805 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
3806 seen, invoke libtoolize with `--ltdl' argument.
3807 * lib/autom4te.in (Autoreconf-preselections): Adjust.
3809 Suggested by Eric Blake.
3811 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
3813 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

3853 * NEWS: GNU make now recommended for VPATH builds.
3854 Mention that some macros are now documented to be obsolescent.
3855 * doc/autoconf.texi:
3856 Prefer "current" to "modern" to describe
3857 currently-used (albeit perhaps old-fashioned) hosts.
3858 Mention which ancient features no longer need to be worried about.
3859 setgid -> set-group-ID
3860 setuid -> set-user-ID (these are the Posix terms)
3861 Fix some misuses of "only".

3874 Mention that it's now safe to use 3 and 4.
3875 (Limitations of Usual Tools): cp -r is now specified by Posix.
3876 Omit longwinded and obsolescent discussion of cp -f.
3877 Modernize discussion of expr, ls.
3878 (Limitations of Make): Modernize discussion of VPATH builds.
3879 Mention $? as a workaround in some cases.
3880 * doc/install.texi (Basic Installation):
3881 Mention "./configure; make; make install" first. Be more
3882 specific about why this file is generic. Remove unnecessary
3883 parens. Remove misleading "only". Remove obsolete advice
3884 about csh. Don't say "configure" takes awhile; say it
3885 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
3886 and CC=c99 rather than CC=c89, as these are blessed by current
3887 Posix. Recommend GNU make if doing a VPATH build.
3889 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
3891 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
3892 examples involving shell prompts.
3894 2006-06-02 Stepan Kasal <kasal@ucw.cz>
3895 and Paul Eggert <eggert@cs.ucla.edu>
3897 * doc/autoconf.texi (Here-Documents): Add details about the
3898 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
3899 use "here-documents" instead of "here documents".
3901 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3903 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
3905 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
3907 * doc/autoconf.texi (File System Conventions): Warn about ":"
3908 anywhere in directory names.
3910 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
3912 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
3913 about quoting the case statement, just in case.
3914 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
3915 was fixed in ksh93g; reported by Ralf Wildenhues.
3917 2006-05-31 Stepan Kasal <kasal@ucw.cz>
3919 * doc/autoconf.texi (System Services): Do not document
3920 overriding EXEEXT via ac_cv_exeext=ext.
3921 (Particular Programs) <AC_PROG_MKDIR_P>:
3922 Document that ${MKDIR_P} understands --.
3923 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
3926 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3928 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
3929 argument with leading hyphen. Problem reported by Paul Eggert.
3931 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3933 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
3934 about quoting ac_try: quote all of it, if any of it seems suspicious.
3935 This means we don't have to worry about ${ or sed any more.
3936 Also, double-quote the case statement, to work around misuses via
3937 underquoting as reported by Ralf Wildenhues in
3938 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
3939 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
3940 undocumented and dangerous macro.
3941 Problem reported by Ralf Wildenhues in
3942 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
3944 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3946 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3947 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3948 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3950 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3952 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3953 since evidently some packages rely on the old, broken behavior.
3954 Problem reported by Ralf Wildenhues in
3955 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3956 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3957 pre-2006-05-26 definitions, but leave in the comments that
3958 these macros are dangerous and should not be used.
3959 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3960 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3961 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3962 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3963 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3965 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3967 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3968 the use of 'tr', since this is our only use of 'tr'.
3970 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3971 and Paul Eggert <eggert@cs.ucla.edu>
3973 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3974 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3976 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3978 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3979 the output file in the `${datarootdir}' test.
3981 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3982 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3984 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3985 mention of `datarootdir' in the input file(s), but literal
3986 `${datarootdir}' in the output file, and we haven't warned yet,
3987 then warn as well: the user may have (erroneously) used
3988 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3989 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3990 * tests/torture.at (datarootdir workaround): Extend this test.
3993 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3994 and Paul Eggert <eggert@cs.ucla.edu>
3996 * doc/autoconf.texi (autoheader Invocation): The first argument to
3997 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3998 alternatives and clear up the language a bit.
4000 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
4002 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
4003 ac_config_guess, ac_config_sub, ac_configure.
4004 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
4005 Fix typo that prevented an unnecessary space from being removed.
4006 Problems reported by Ralf Wildenhues in:
4007 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
4009 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
4011 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
4012 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
4013 Don't use the term "thread-safe" to talk about mkdir race
4014 conditions, since the problem is more a process than a thread
4015 issue. Problem reported by Stepan Kasal in:
4016 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
4017 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
4018 the test for 'install' more closely. Look at MKDIR_P first.
4019 Look in the PATH, and at /opt/sfw/bin.
4020 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
4021 Don't bother to try mkdir -p, since we already check mkdir --version;
4022 just look at the version number. (There's no easy way to check
4023 for race-free implementations.)
4024 * tests/tools.at (autoconf: subdirectories): Adjust to above
4025 changes, since MKDIR_P now might end in "/mkdir -p".
4027 * doc/autoconf.texi (autoheader Invocation): Mention that the
4028 first arg of AC_DEFINE_UNQUOTED must be a literal.
4029 Problem reported by Ben Pfaff in
4030 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
4032 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
4033 * doc/autoconf.texi (Special Chars in Variables): New section.
4034 (Preset Output Variables): Warn about special chars in CPPFLAGS.
4035 (Installation Directory Variables): Quote $(datadir) better.
4036 (Limitations of Builtins): Describe some of eval's trickiness.
4038 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
4039 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
4040 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
4041 in front of every arg, not just trailing args. Quote apostrophes.
4042 (_AC_EVAL_ECHO): New macro.
4043 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
4044 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
4046 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
4047 exposed by quoting of eval argument. Put the command on line line
4049 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
4050 (_AC_PATH_X, AC_PATH_X): Quote more safely.
4051 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
4052 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
4053 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
4054 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
4055 Use eval more safely.
4056 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
4057 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
4059 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
4060 lines, exposed by quoting of eval argument.
4062 2006-05-26 Stepan Kasal <kasal@ucw.cz>
4063 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4065 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
4066 initialization of `ac_cv_exeext', do not override it if it was
4067 already set, unless it was set to `no', for compatibility with
4068 Autoconf-2.13, and comment this.
4069 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
4070 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
4071 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
4072 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
4073 Document that this test may be overridden by setting
4076 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4078 Revert these two patches:
4080 2006-04-06 Eric Blake <ebb9@byu.net>
4081 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
4082 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
4085 2006-04-01 Stepan Kasal <kasal@ucw.cz>
4086 Clean up _AC_COMPILER_EXEEXT* macros.
4087 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
4088 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
4089 ac_file to the name of the default output file and call
4090 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4091 initial `rm' of the candidate files...
4092 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4093 the same list in subsequent `rm' calls, and for the temporary
4094 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4095 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4096 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4097 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
4098 no longer needed) by libtool. Make it a cache check.
4099 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
4100 copied here by mistake.
4101 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
4102 _AC_COMPILER_EXEEXT.
4103 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
4104 _AC_COMPILER_OBJEXT directly.
4105 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4107 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4109 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
4110 Fix description of how the buggy `sed' works.
4112 2006-05-25 Noah Misch <noah@cs.caltech.edu>
4116 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
4117 ENOLCK. Only mention `make -j' when applicable. Only raise
4118 fatal errors when `make -j' is involved. Improve error message.
4120 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4122 * doc/autoconf.texi (Here-Documents): We now know more about
4123 the variable expansion in here documents bug.
4124 Thanks to Tim Rice and Stepan Kasal.
4126 * doc/autoconf.texi (Making testsuite Scripts): Add an example
4127 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
4129 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4131 * tests/autotest.at (Multiline command from M4 expansion):
4132 No failure to be expected if the shell quotes newlines in
4133 commands in the `set -x' output. Report by Tim Rice.
4136 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4138 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
4139 expansion in the here-documents used by config.status, as that
4140 runs afoul of the Korn shell version M-12/28/93d bug described in
4141 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
4142 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
4143 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
4145 2006-05-23 Jim Meyering <jim@meyering.net>
4147 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
4148 Fix typo introduced with 2006-04-02 change. It reversed the sense
4151 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
4153 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
4154 ac_dB slightly, to save bytes in the script.
4155 Max out at 50 lines, rather than 96; this is more likely
4156 (though not guaranteed) to avoid obscure 'sed' failures.
4158 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4160 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
4161 `tr -d -' as bad option argument. Work around this by deleting
4162 an unrelated character.
4163 Report by Tim Rice <tim@multitalents.net>.
4165 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
4166 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4167 Stepan Kasal <kasal@ucw.cz>
4169 * doc/autoconf.texi (Particular Programs): Do not promise that
4170 we always prefer the GNU version of the program, and that we
4171 search according to PATH; both rules can have exceptions.
4172 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
4173 AC_PROG_SED. Move descriptions of limitations
4174 to the Limitations of Usual Tools section.
4175 (Limitations of Usual Tools) <sed>: Mention script length
4176 limitations with Solaris /usr/ucb/sed.
4177 <grep>: Fix wording for empty alternative. Mention that -c and
4178 -l should not be combined, and that -E and -F should not be
4181 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4182 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4184 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
4185 limits in Solaris 8 /usr/ucb/sed by testing a long script.
4187 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4189 * doc/autoconf.texi (Defining Symbols): Literal parameter of
4190 AC_DEFINE is now passed to m4_pattern_allow.
4191 * NEWS: Mention that; likewise for AC_SUBST.
4192 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
4193 the parameter to m4_pattern_allow.
4194 * tests/tools.at: Add a check for that.
4196 2006-05-22 Stepan Kasal <kasal@ucw.cz>
4198 * lib/autoconf/status.m4: Fix typos.
4200 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4202 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
4203 only the files that this macro generates.
4205 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4207 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
4208 the HP-UX sed limitation of 99 commands, labels do not count.
4209 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
4211 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
4213 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
4215 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
4216 Import the following fix from coreutils:
4218 2006-01-13 Jim Meyering <jim@meyering.net>
4220 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
4221 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
4222 not double-quote uses of that variable, to accommodate the rare
4223 case in which getmntent is available in none of the libraries
4224 checked. This happens at least on FreeBSD 5.0.
4226 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
4228 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4229 ac_config_guess, ac_config_sub, and ac_configure, since evidently
4230 some other programs unwisely rely on these undocumented vars.
4231 But put in warning comments about them.
4232 Problem reported by Ralf Wildenhues in
4233 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
4234 * NEWS: Document that these variables are intended to go away.
4236 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4238 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
4239 and set the language to C++ (analogous to the equivalent Fortran
4242 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
4243 * doc/autoconf.texi (C++ Compiler): Document it.
4244 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
4247 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
4249 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
4250 that caused config.status to generate 100-command sed scripts; the
4251 portable limit is 99.
4253 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4255 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
4256 variable `ac_d' instead of `d' to avoid infringing namespace.
4257 Report by Ralf Menzel.
4259 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
4261 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
4262 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
4263 * tests/tools.at (autoconf: subdirectories): New test, taken from
4264 the corresponding problem report by Ralf Wildenhues in:
4265 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
4267 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
4268 Quote some uses of shell variables if they might suffer unexpected
4269 globbing. This doesn't fix all instances of quoting problems that
4270 I found, just the easy ones that look safe.
4271 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
4272 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
4273 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
4274 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
4275 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
4276 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
4277 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
4279 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
4280 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
4282 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4284 * bin/autoreconf.in ($help): Reword according to the manual.
4285 Suggested by Olly Betts.
4287 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
4288 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4290 * bin/autoreconf.in: Pass the directory argument to
4291 `require_configure_ac'. Fix comment.
4292 * tests/torture.at (Configuring subdirectories): Expose this.
4293 Reported by Olly Betts.
4295 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4297 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
4298 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
4299 Automake as follows:
4301 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
4302 `$configure_in' instead of `configure.in', to preserve
4303 directory component.
4305 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4307 * config/config.guess, config/config.sub, config/texinfo.tex,
4308 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
4310 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
4312 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
4313 test for C99 conformance; (bool) 0.5 is an integer constant
4314 expression, but (bool) -0.5 is not. Problem reported by Fedor
4315 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
4317 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
4319 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
4320 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
4321 Warn about obsolete install-sh files. Remove stray sentence
4322 fragment and fix cross reference.
4323 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
4324 install -d; this undoes the 2006-05-10 change.
4325 (MKDIR_P): Mark with AN_MAKEVAR.
4326 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
4327 that we don't require $INSTALL to be thread-safe. Move comments
4328 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
4329 of AC_PROG_INSTALL. Output a message saying that we're checking
4330 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
4331 MKDIR_P instead of AC_SUBST.
4332 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
4333 Special magic for MKDIR_P, too.
4334 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
4336 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
4338 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
4340 Sync from Automake, as follows:
4342 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4343 * config/install-sh: Initialize IFS, so field splitting isn't
4345 * config/mkinstalldirs: Likewise.
4346 * config/missing: Remove superfluous quotes. Replace all uses of
4347 `[' by `test', for consistency, and for..
4348 * config/missing (sed_minuso, sed_output): New variables.
4349 (autom4te, help2man, makeinfo): Use them. Unifies detection of
4350 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
4351 Fixes `missing' to detect `--output' for help2man. Fixes
4352 PR automake/483. Report by Dennis J. Linse.
4353 (autom4te): Document in `missing --help'.
4355 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4357 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
4358 * config/install-sh: Don't use 'path' to talk about file names,
4359 as per GNU coding standards. Close a race condition reported by Ralf
4360 Wildenhues and Stepan Kasal. There is still a race condition
4361 on hosts that predate Posix 1003.1-1992, but we can't help this.
4362 Don't mishandle weird characters like space on pre-Posix hosts.
4363 Invoke mkdir at most once per dir arg on pre-Posix hosts.
4364 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
4365 AC_PROG_MKDIR_P from AS_MKDIR_P.
4366 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
4367 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
4368 earlier editions are not (including Automake 1.8.3).
4369 Do not suggest mkinstalldirs for thread-safety.
4370 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
4371 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
4372 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
4373 presence of special characters and race conditions.
4374 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
4375 in Autoconf's name space.
4377 2006-05-10 Bruno Haible <bruno@clisp.org>
4378 and Paul Eggert <eggert@cs.ucla.edu>
4380 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
4381 from Automake with minor changes.
4382 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
4384 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
4386 * config/install-sh: Update to Automake CVS version, as follows:
4387 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4388 * lib/install-sh: Simplify the expr implementation of dirname.
4389 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
4390 * lib/install-sh: Handle --, and diagnose unknown options.
4392 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4394 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
4395 `./autom4te' to create `./testsuite', since the `all' target
4396 will ensure its presence, but `installcheck' should not create
4397 the uninstalled wrappers.
4399 * tests/torture.at (Unusual Automake input files): Skip if we
4400 detect automake < 1.8.
4402 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4404 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
4405 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
4406 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
4409 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4411 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
4412 munge (multiple) white space and other oddities.
4413 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
4414 single quotes in variable assignment.
4415 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
4416 and similar failures by adding multiple spaces, tabs, and other
4418 Report and different test suggested by Francesco Romani
4419 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
4421 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
4422 single quotes, we only need to search for single quotes; this
4423 both simplifies the search pattern, and makes us less
4424 susceptible to `echo' variations for arguments not containing
4426 (_AC_ARG_VAR_VALIDATE): Likewise.
4428 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4430 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
4431 `$*' and IFS concatenation issue with traditional shells and
4432 bash-2.04. Report by Seanster@Seanster.com.
4434 2006-05-03 Bruno Haible <bruno@clisp.org>
4436 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
4437 precisely which Mac OS X versions have the od problem.
4439 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4441 * doc/autoconf.texi: Use @option systematically.
4443 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
4444 and Bruno Haible <bruno@clisp.org>
4446 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
4448 (Integer Overflow): Mention the special case of integer division
4451 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4453 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
4454 traditional shells like the Solaris one that do not use the
4455 first IFS character for assembling `$*'.
4456 Prompted by a related report from autoconf_bug@nro.ca.
4458 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
4459 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4461 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
4462 Mention more problems with the -e option.
4464 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4467 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
4469 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
4470 in URLs to improve DVI formatted output (requires texinfo 4.6).
4471 (System Services, Systemology, Shellology): Likewise.
4472 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
4475 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
4477 (Runtime): Fix macro argument names to match description:
4478 `action-if-found' -> `action-if-true' and similarly.
4479 (Obsolete Macros): Likewise.
4480 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
4481 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
4482 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
4484 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4486 * doc/autoconf.texi (Limitations of Make): Clean up markup.
4489 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
4492 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4494 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
4495 /bin/sh set unsorted output.
4496 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
4497 * tests/local.at: Likewise.

4501 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
4502 (Integer Overflow, Null Pointers, Buffer Overruns):
4503 (Floating Point Portability, Exiting Portably): New sections.
4504 (Writing Test Programs): Fix some langauge. Recommend exiting
4505 with status 1, not merely nonzero. Clarify exit declaration.
4506 (Run Time): Move C exit status stuff to new Exiting Portably section.
4507 (Systemology): Mention Posix and levenez. Update v7 reference.
4508 (Portable Shell): Mention the Posix shell.
4510 2006-04-25 Stepan Kasal <kasal@ucw.cz>
4512 * bin/autoconf.as (me): Replace by as_me.
4514 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
4516 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
4517 since as_me isn't set yet.
4519 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4521 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
4522 a few minor bugs in this area.
4524 * doc/autoconf.texi (Programming in M4sh): Comment out the
4525 documentation of AS_BASENAME, for now.
4526 (Shell Substitutions): Do not use AS_DIRNAME in an example.
4527 (Limitations of Builtins) <basename>: Do not refer to
4529 * bin/autoconf.as (me): Don't use AS_BASENAME.
4530 (dir): Remove the unused variable.
4531 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
4532 AS_DETECT_REQUIRED. All uses changed.
4533 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
4535 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
4536 (AS_BASENAME): Use "basename --" to protect against leading "-".
4537 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
4538 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
4539 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
4540 (_AS_DIRNAME_PREPARE): Likewise.
4541 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
4542 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
4543 (AS_DIRNAME): Use "dirname --".
4545 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
4547 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
4548 of "run time" and "run-time" changed to "runtime", for consistency.
4549 * lib/autoconf/fortran.m4: Likewise (in comment).
4550 * lib/autoconf/functions.m4: Likewise.
4551 * lib/autoconf/general.m4: Likewise.
4552 * lib/autoconf/headers.m4: Likewise.
4554 * doc/autoconf.texi (Run Time): Document the exit status situation
4555 with more accuracy and detail.
4557 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4559 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
4560 Archive is not officially `GNU' any more. Update URL.
4561 (Defining Directories): Likewise
4562 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
4564 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4566 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
4567 newline from the `trap' code to finish `config.log'; the NetBSD
4568 /bin/sh resets the exit status after an empty command, as
4569 documented in doc/autoconf.texi.
4570 Reported by Dalibor Topic <robilad@kaffe.org>.
4572 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
4574 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
4575 Suggested by Bruno Haible.
4577 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
4579 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
4580 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
4581 Instead, just list the shells that we know work.
4582 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
4583 changed. Be more cautious about the _cv_ variable.
4584 * tests/tools.at (Syntax of the shell scripts): Check the
4585 _cv_ variable once, at first, to avoid an internal autoconf error
4586 when sh -n does not work.
4588 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4590 * lib/Autom4te/FileUtils.pm: Sync from Automake.
4592 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
4594 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
4595 use ">&-" since we're only 99.999% sure that this is portable,
4596 and since the MinGW bug is fixed in a different way.
4597 * lib/autotest/general.m4 (AT_INIT): Likewise.
4599 2006-04-16 Stepan Kasal <kasal@ucw.cz>
4601 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
4602 before opening config.log, to avoid hitting a bug on MinGW.
4604 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
4606 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
4607 AS_MESSAGE_LOG_FD before reopening it onto the log file.
4608 This works around a MinGW bug reported by Eric Paire.
4609 Make sure that all writes to the log file append to it,
4610 rather than possibly losing data.
4611 * lib/autotest/general.m4 (AT_INIT): Likewise.
4613 2006-04-14 Stepan Kasal <kasal@ucw.cz>
4615 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
4618 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4622 * configure.ac (AC_INIT): Bump to 2.59d.
4624 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4628 * Makefile.maint (news-date-check): Do not require a leading `*'
4629 before the release date in NEWS.
4631 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4632 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4634 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
4635 the instantiated file do not contain the string 'datarootdir'
4636 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
4637 @mandir@, replace the reference '${datarootdir}' by the value.
4638 * tests/torture.at (datarootdir workaround): New test.
4639 * NEWS: Advertise this temporary fixup.
4640 Based on a patch by Bruno Haible, reported and analyzed by
4641 Paul Eggert and Noah Misch.
4643 2006-04-12 Eric Blake <ebb9@byu.net>
4645 * tests/autotest.at (Debugging a failed test): Fix comment.
4647 2006-04-12 Stepan Kasal <kasal@ucw.cz>
4649 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
4650 all the changes since 2006-04-07.
4652 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4654 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
4655 succeeded, but `ln -s file dir' failed, take care to remove the
4656 leftover target before the next test, to prevent its spurious
4657 failure; also make sure `ln file dir' works before selecting it.
4658 Thanks to Keith Marshall for pointing this out.
4661 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4662 assignments in `at_debug_args', so that we put them correctly
4663 in the `run' script.
4664 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
4665 Reported by Eric Blake.
4667 2006-04-11 Eric Blake <ebb9@byu.net>
4669 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
4670 top-level tests after micro-suite has been run. Used in...
4671 (Debugging a successful test, Debugging script and environment),
4672 (Debugging a failed test): ...these new tests. The first of these
4674 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
4675 macro, split out from...
4676 (AT_INIT): ...here, so that using -d also generates a run script.
4677 Document that -d inhibits top-level logging.
4678 * doc/autoconf.texi (testsuite Invocation): Document that -d only
4679 inhibits top-level logging; debug scripts are created.
4681 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
4683 * tests/autotest.at (Empty test, Empty check): New test to check it.
4685 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
4688 2006-04-10 Stepan Kasal <kasal@ucw.cz>
4690 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
4691 the files if a problem appears. Make the empty *.at files
4692 read-only, too. Proposed by Ralf Wildenhues.
4694 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4696 * config/Makefile.am: Add comment to force updated Makefile.in.
4698 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
4699 space only patch to this file, this patch causes the Makefile.in
4700 files that include freeze.mk to be updated, and thus have a
4701 newer time stamp again, which in turn makes a pristine CVS
4702 checkout have correct time stamps.
4704 * Makefile.maint (cvs-sv): New macro, to be used..
4705 (config.guess-url_prefix, config.sub-url_prefix)
4706 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
4707 point to CVS text checkout of Gnulib files.
4708 (copyright-check): Bump current year.
4709 (announcement): Do not hard-wire `./announce-gen'.
4710 (cvs-update): Propagate failures of `cvs' and `move-if-change'
4712 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
4714 (wget_files): Update config.guess, config.sub, texinfo.tex by
4715 `wget-update', now that their URLs work again.
4717 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4719 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
4720 Problem noted by Paul D. Smith.
4722 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4724 * doc/autoconf.texi: Remove unused words from word list.
4725 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
4726 .x-sc_trailing_space: New files.
4728 * doc/standards.texi: Sync from gnulib.
4730 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
4731 `LIBOBJDIR' as experimental.
4733 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
4734 with a target directory; it's internally implemented as `cp'
4735 anyway, but since Autoconf advertises the possibility to use
4736 a target directory when LN_S is `ln -s', we need to find out.
4737 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
4738 analyzed by Keith Marshall <keith.marshall@total.com>.
4742 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
4744 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
4745 confdefs.h as-is. In general, if it has backslash-newline or the
4746 like, then it doesn't work either to sort or to remove empty
4749 2006-04-09 Stepan Kasal <kasal@ucw.cz>
4751 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
4753 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
4755 * lib/autom4te.in (Automake-preselections): Preselect
4758 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4760 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
4761 apostrophe within a single-quoted string, as this is the usual
4762 tradition and is easier to read than '"'"'. Don't rely on the
4763 shell treating "$/" like '$/'. Use a more-consistent indenting
4766 2006-04-09 Eric Blake <ebb9@byu.net>
4768 * tests/autotest.at (Backquote command substitution),
4769 (Multiline backquote command substitution): Remove mistaken
4770 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
4772 (Parenthetical command substitution, Multiline parenthetical
4773 command substitution): here.
4775 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
4777 Import macros from gnulib (often changing their name).
4779 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
4780 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

4884 AS_MKDIR_P exits the script on failure.
4885 * lib/autotest/general.m4: Remove redundant AS_ERROR.
4887 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4906 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4908 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
4909 whether `set' quotes correctly: redirect stderr of the tested
4910 `set', and use a subshell, for Ultrix; use `sed' instead of
4911 `grep' for zsh `set' which may write binary output; match only
4912 at the beginning of a line, to avoid false positives.
4913 In order to avoid false positives by unrelated variables with
4914 multiline content, put the dump algorithm in a subshell and
4915 unset all variables containing newlines (except some which are
4916 special to the shell). Warn about cache variables that are

4962 ac_config_<foo>s again, sometimes normalized, sometimes not.
4963 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4964 (AC_CONFIG_COMMANDS): Do not do so here.
4965 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4966 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4967 2005-07-25 rewrite. Noticed by Noah Misch.
4969 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4970 _AC_PRESERVE_HELP_ORDER, ...

4977 for --help from Cygnus `configure.'
4979 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

5027 Use simplified args that Eric Blake originally suggested.
5029 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
5031 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
5032 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

5036 (exclude_list): Exclude empty macros.
5037 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

5120 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5121 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5122 ac_file to the name of the default output file and call
5123 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5124 initial `rm' of the candidate files...
5125 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5126 the same list in subsequent `rm' calls, and for the temporary

5129 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5130 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5131 no longer needed) by libtool. Make it a cache check.

5133 copied here by mistake.

5208 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5210 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
5211 switch all of them on and of when necessary. Fixes the bug when

5909 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
5910 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
5911 by the function rather than ignoring it.
5912 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
5913 comparing its address. Intel's interprocedural optimization was
5914 outsmarting the old heuristic. Problem reported by

5932 Stepan Kasal <kasal@ucw.cz>
5934 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
5935 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
5936 make its content writable before removing it. Remove an errorneous
5937 comment from the end, where the logs of the failed tests are copied
5938 to the main log file.
5940 2005-09-27 Stepan Kasal <kasal@ucw.cz>
5942 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

5947 problems if the testsuite were running too fast.
5949 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
5951 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
5952 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
5953 (which belong to Xt, not X itself). See Debian bug 327655.
5954 * NEWS: Mention this.
5956 2005-09-07 Stepan Kasal <kasal@ucw.cz>

5963 suggested by Ben Elliston. Handle weird characters correctly.
5965 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5967 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5968 calls, so that the final expansion of this macro is shorter.
5969 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5970 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5971 the cleanup there. Use AS_VAR_* macros, to be more general.
5972 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5974 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5976 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

5994 2005-08-26 Stepan Kasal <kasal@ucw.cz>
5996 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5997 in the example. Reported by Bruno Haible.
5998 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5999 "if $undefined_var;" succeeds with my shell.
6001 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
6002 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
6003 but change the m4_divert_text to m4_divert_once.
6005 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
6007 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
6008 Work around bug in Solaris /usr/xpg4/bin/awk.
6009 The bug is present in at least Solaris 8 through 10.
6011 2005-08-24 Stepan Kasal <kasal@ucw.cz>
6013 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
6014 some evil values and relying on the fact that $* concatenates the
6015 parameters by the first character from IFS.

6021 first header appears, define AH_HEADER.
6022 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
6023 Update limitations about when to call AC_CONFIG_HEADERS.
6024 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
6025 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
6026 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
6027 ``Configuration Actions''; fix their index entries.
6029 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
6030 options correctly. Process N-M as M-N if M is smaller than N.
6031 Process ranges correctly so that N-N will run only N.
6032 Sort and uniquify the tests that will be run. If there is more
6033 than one test, reinsert the banners for the tests.

6036 2005-08-23 Stepan Kasal <kasal@ucw.cz>
6038 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
6039 before passing the macro name to AH_TEMPLATE.

6042 now opens log after option processing; in particular, --version
6043 and --help do not touch config.log.

6060 Prepend to LIBS, not append, in examples.
6062 2005-08-16 Stepan Kasal <kasal@ucw.cz>
6064 When building in place, set srcdir="."; suggested by Tim Van Holder.
6066 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
6067 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
6068 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
6069 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
6070 does not mean "no --srcdir option".
6072 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6074 * tests/autoscan.at (autoscan): New file.

6083 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
6084 add "2>&1"; gzip 1.2.4 prints help on stderr.
6086 2005-07-27 Stepan Kasal <kasal@ucw.cz>
6088 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
6089 was pushdef'ed twice while popped only once. Push it only once.
6090 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
6092 2005-07-26 Stepan Kasal <kasal@ucw.cz>
6094 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

6101 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
6102 "<tab>" in comment, so that the point is understandable.
6104 2005-07-25 Stepan Kasal <kasal@ucw.cz>
6106 Rewrite substantial part of lib/autoconf/status.m4.
6107 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
6108 and CONFIG_COMMANDS are not processed in four separate loops.
6109 Instead, there is one main loop. This alows that the common code
6110 is expanded only once, thus config.status (and configure) is smaller.
6112 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
6113 the AC_LIST_FILES and cousins macros are no longer used.
6115 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
6116 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
6117 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
6118 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
6119 contain the initialization, nor the for loop, nor the associated
6120 commands; all these go to ...
6121 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
6122 _AC_OUTPUT_CONFIG_STATUS.
6123 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
6124 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
6125 (_AC_OUTPUT_FILE): The creation of the sed script ...
6126 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
6127 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
6128 _AC_OUTPUT_MAIN_LOOP.
6129 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
6130 _AC_CONFIG_COMMANDS): Use ...
6131 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
6132 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
6133 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
6134 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
6135 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
6136 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
6138 (_AC_CONFIG_UNIQUE): Update.
6139 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
6140 Replaced by this ...
6141 (_AC_LIST_TAGS): ... new common macro.
6142 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
6143 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
6144 (_AC_LIST_TAG_COMMANDS): ... new common macro.
6145 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
6146 this didn't belong to the `config commands' section.
6147 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
6148 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
6149 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
6150 to the `config commands' section either.
6151 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
6152 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
6154 ... and many changes to the comments nearby.
6156 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
6157 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
6158 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6159 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
6160 (#define header templates): The comment at the top of the generated
6161 header now includes the name(s) of the source file(s).
6163 Several unrelated small changes:
6165 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
6166 parameter to AC_DIAGNOSE.
6167 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
6168 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages

6269 configure_input, top_builddir, srcdir, etc.
6270 * lib/autotest/general.m4 (AT_INIT): Likewise, for

6281 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

6342 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

6363 variable into diagnostic. Make the diagnostic an error, not a warning,
6364 because we really don't support spaces and suchlike in dir names.
6365 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
6366 Don't worry about backslashes in srcdir; it can't happen now.

6410 * doc/autoconf.texi:
6411 Don't mention Solaris versions so much, if a
6412 problem is common to all extant versions of Solaris. Say "SunOS
6413 4" instead of "SunOS" for SunOS 4.
6414 (awk): Mention more of the limitations of traditional Awk.

6458 -u, since it outputs chatter if the input files are the same.
6459 Problem reported by Ralf Menzel.
6461 2005-06-08 Derek Price <derek@ximbiot.com>
6463 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
6464 renaming them since they are about to be redefined anyhow.

6475 * doc/autoconf.texi (Introduction): Likewise.
6476 Reword to avoid some formatting glitches.

6481 might get inadvertently cut-and-pasted into user code.

6505 m4_cdr of one-member list was [[]] (one-member list containing an
6506 empty string) instead of [] (an empty list. Callers were skewed to
6507 match this misbehaviour. As a consequence of this:
6508 - m4_foreach([x], [], [foo]) expanded to `foo', while
6509 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
6510 This bug has been fixed:
6512 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
6513 expand to an empty string; print error msg if called without
6515 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous

6526 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
6527 swallow records with more than 99 fields.
6528 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
6529 parse the long line.
6531 2005-06-04 Stepan Kasal <kasal@ucw.cz>
6533 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

6638 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
6641 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6643 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
6644 argument to m4_foreach. I guess it was necessary in the past,
6645 but I think it's a no-op now.
6647 2005-05-17 Stepan Kasal <kasal@ucw.cz>
6649 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
6650 ``cat <<_ACEOF'' commands to one.
6651 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
6652 * lib/autoconf/status.m4: On various places, use expr instead of
6654 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
6655 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
6656 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
6658 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
6659 the wrong patterns between ``case'' and ``esac.'' The previous
6660 code had false positives.
6662 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
6664 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

6712 enough arguments, similarly as in m4_bpatsubsts.
6714 2005-05-12 Stepan Kasal <kasal@ucw.cz>
6716 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
6719 2005-05-11 Stepan Kasal <kasal@ucw.cz>
6721 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
6722 for absolute directory names in one loop.

6724 abbreviations of --version and --debug.
6726 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
6728 * doc/autoconf.texi (Autoconf Language): Be more precise about
6729 quoting rules. Problems noted by Stepan Kasal.
6730 Also, throughout this document, be more careful about white space.
6731 "blank", "white space", and "space" all have different meanings
6732 and we should be careful to say what we mean.
6734 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
6736 Fix C++ related problems reported by Werner Lemberg.
6737 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
6738 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
6739 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
6740 avoid problems with C++ and throw.
6741 * tests/compile.at: .cpp, not .cc.
6743 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
6745 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6747 * doc/autoconf.texi (Generic Functions): Typos.
6749 2005-05-02 Gary V. Vaughan <gary@gnu.org>
6751 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
6752 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
6753 set by latest automake.
6755 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
6757 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
6758 outputs 0 on GNU/Linux these days.
6760 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
6762 * doc/autoconf.texi (Autoconf Language): Add more description
6763 about quoting heuristics.
6764 (Limitations of Builtins): Describe "set -" problems.
6766 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6768 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
6771 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
6772 by AC_DEFINE; it was a mistake.
6773 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
6775 2005-04-25 Stepan Kasal <kasal@ucw.cz>
6777 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
6779 2005-04-22 Stepan Kasal <kasal@ucw.cz>
6781 * doc/autoconf.texi (External Software): Quadrigraphs are not
6782 processed correctly in AS_HELP_STRING; avoid this in the examples.
6783 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
6784 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
6785 comment and reduce m4_default([foo], []) to [foo].
6786 (m4_strip): Update the explanation.
6788 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
6790 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
6791 Remove core.conftest.* too; it's generated by Tru64 5.1.
6792 Problem reported by Jennis Pruett.
6793 * lib/autoconf/functions.m4
6794 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6795 Don't bother to remove core files; AC_RUN_IFELSE should do that
6798 2005-04-19 Stepan Kasal <kasal@ucw.cz>
6800 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
6802 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
6804 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
6805 Report from Horst Wente.
6807 2005-04-15 Stepan Kasal <kasal@ucw.cz>

6814 * doc/autoconf.texi (External Software, Package Options): Add
6815 examples showing how to implement --with-* and --enable-* options.
6817 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
6819 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
6820 as well as configure.in. Problem reported by Gregorio Guidi.
6822 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
6824 * doc/autoconf.texi (Particular Functions): Use gnulib's current
6825 pattern for alloca snippet.

6835 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
6837 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
6838 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
6840 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6842 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
6843 Merge `-z option' as well for the benefit of Solaris link flags. Pass
6844 whole-archive (-zallextract, -zdefaultextract) options in the hope of
6845 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
6846 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
6848 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
6850 * NEWS: The configure command now warns you if you attempt to use
6851 a directory whose name contains a special character like space,
6853 * doc/autoconf.texi (Installation Directory Variables): Allow
6854 "," in file names. Do not use \@; it's not a portable regexp.
6855 * bin/Makefile.am (edit): Likewise.
6856 * lib/Makefile.am (edit): Likewise.
6857 * tests/Makefile.am (edit): Likewise.
6858 * tests/semantics.at: Likewise.
6859 * tests/torture.at: Likewise.
6860 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
6861 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
6862 * doc/autoconf.texi (File System Conventions): Warn about
6863 unportable file names.
6864 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
6866 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
6867 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
6868 ac_pwd, and quote srcdir.
6869 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
6871 * doc/autoconf.texi: Fix some systematic formatting problems.
6872 ".)" needs a following @: if not at the end of a sentence, and
6873 similarly for "!)". "etc." should be preceded by a comma.
6874 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
6876 2005-03-22 Bruno Haible <bruno@clisp.org>
6878 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
6879 argument is often called 'build-aux'.
6881 2005-03-07 Stepan Kasal <kasal@ucw.cz>
6883 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
6884 macro AC_TRY_LINK is obsolete.
6885 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
6888 2005-02-24 Stepan Kasal <kasal@ucw.cz>
6890 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
6891 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
6892 from a Common Lisp's `cl'.
6893 (AC_PROG_CXX): Behave according to the documentation: don't
6894 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
6895 make the variable CCC precious; use `cl.exe', not `cl'.
6897 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6898 Alexandre Duret-Lutz <adl@gnu.org>
6900 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
6901 /dev/null, as "configure" shouldn't read stdin, and this insulates
6902 us from problems (e.g., when testing for "cl"). Also, do this
6903 redirection before invoking "hostname" or "uname", and keep the
6904 original input stream available via...
6905 (AS_ORIGINAL_STDIN_FD): ... this new macro.
6906 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
6907 bother with "</dev/null" since it's now done at the top of
6909 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
6910 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6911 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6912 * doc/autoconf.texi (File Descriptor Macros): New section.
6913 (Printing Messages): Mention it.
6914 * tests/base.at (Input/Output): New test.
6916 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
6918 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
6919 newline if neither \c nor -n work, as that would output two
6920 newlines. Prefer -n to \c. Reported by Stepan Kasal.
6922 2005-02-12 Stepan Kasal <kasal@ucw.cz>
6924 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
6925 This causes that any required macros inside will get before the if.
6926 * doc/autoconf.texi (autom4te.cache): A typo.
6928 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
6930 Undo previous change, except keep the change to
6931 lib/autoconf/programs.m4 that replaced grep with shell
6932 pattern-matching. This is because net-snmp configure reads stdin.
6933 Reported by Noah Misch.
6935 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
6937 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
6938 from /dev/null, as "configure" shouldn't read stdin, and this
6939 insulates us from problems (e.g., when testing for "cl").
6940 Suggested by Alexandre Duret-Lutz. Also, do this redirection
6941 before invoking "hostname" or "uname".
6942 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6943 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
6944 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
6945 "</dev/null" since it's now done at the top of 'configure'.
6946 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6947 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6948 Also, replace grep with shell pattern-matching, to save a process.
6950 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6952 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6953 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6954 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6957 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6959 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6960 grep -q isn't portable. Improve grep -s explanation.
6961 Problem reported by Dan Manthey.
6963 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6965 * doc/autoconf.texi (Special Shell Variables): Clarify
6966 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6968 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6970 * doc/autoconf.texi: Use @acronym for DJGPP.
6971 Fix some @code's that should have been @env's, and vice versa.
6972 Sort environment variable names.
6973 Mention that shells no longer inherit IFS.
6974 Don't recommend PATH_SEPARATOR=';' so strongly.
6975 Mention that $RANDOM might expand to the empty string.
6976 "symlink" and "soft link" -> "symbolic link".
6977 Improve mktemp description (reported by Bruno Haible).
6979 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6981 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6982 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6984 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6987 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6989 * NEWS: Mention AT_COPYRIGHT.
6991 * tests/local.at (AT_CMP): Use diff directly on input files rather
6994 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6995 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6997 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6998 and Paul Eggert <eggert@cs.ucla.edu>
7000 * tests/autotest.at (Empty test suite): New test.
7001 * tests/torture.at (Substitute and define special characters)
7002 (Substitute a 2000-byte string, Define to a 2000-byte string)
7003 (Substitute a newline, Define a newline): New tests.
7005 2005-02-04 Noah Misch <noah@cs.caltech.edu>
7007 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
7008 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
7009 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
7010 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
7011 (Standard regular expressions): New test.
7012 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
7013 excess test name quoting.
7014 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
7015 CPPFLAGS to `configure' instead of setting it in `configure'.
7017 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
7018 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
7021 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
7022 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
7024 * tests/local.at (AT_CMP): New macro.
7025 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
7026 (AC_SAVE_STATE): Move environment grep...
7027 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
7028 (AT_CONFIG_CMP): New macro.
7029 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
7030 * tests/c.at (Extensions): Do not exit early.
7031 * tests/atlocal.in: Inherit $GREP.
7033 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
7034 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
7036 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
7037 (AC_COPYRIGHT): Factor header comment portion out and move into...
7038 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
7039 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
7040 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
7042 * tests/local.at: Add Autoconf test suite copyright notice.
7043 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.

7050 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
7052 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
7053 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
7055 Try not to generated lines of unlimited length, as POSIX places a
7056 2047-byte limit on line length of portable text files.
7057 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
7058 Use newline as a separator, not space.

7060 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
7063 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7065 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
7066 as_func_*. Add test to check whether positional parameters
7067 are restored after function return.
7069 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
7071 * doc/autoconf.texi (Special Shell Variables): Mention _,
7072 BIN_SH, DUALCASE. Say that variables other than "status" are safe
7073 if they contain a lower-case letter. The DUALCASE problem was
7074 reported by Ralf Wildenhues.
7076 * bin/autoconf.as: Don't exit with status 0 after write failure
7077 with --help or --version.

7116 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
7117 Update the long comment explaining it.
7119 m4_require no longer writes an ``is required by'' line to the
7120 execution stack. It contains only one bit of non-redundant
7121 information: that the macro was required, not called. And even
7122 this bit is useless in most situations: have you ever met a macro
7123 which both calls and requires the same macro?
7125 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
7126 (_m4_defun_pro_outer): ... only via this macro, for the outermost

7133 (_m4_require_call): Use it.
7134 * tests/m4sugar.at (m4_require): Expect output without the
7135 ``is required by'' messages.
7137 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

7173 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
7174 Warn about newline stripping in `` and $(). Update Solaris
7176 (Limitations of Builtins): Use expr "X...", not expr "x...", as
7177 X insulates us from future changes to Posix.
7178 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

7203 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
7205 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

7231 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
7232 stored in _m4_divert_diversion or _m4_divert_dump.
7233 (m4_divert_pop): When the parameter is given, compare the symbolic
7234 name with the last diversion pushed on the stack. Previously, the
7235 current diversion was compared with the numeric value of the
7236 diversion given as the parameter.
7237 (m4_require): If the macro hasn't been expanded yet, call ...
7238 (_m4_require_call): this new macro.

7271 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

7545 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
7546 "char c = '\200';" rather than "char c = 0x80;" as the
7547 latter doesn't conform to the strict C standard due to
7548 overflow on signed char hosts.
7550 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
7551 to -qlanglvl=ansi. We don't want to disable extensions.
7553 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
7555 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
7556 (Using Autotest, testsuite Scripts, Writing testsuite.at):

7607 simplify the examples and improve their quoting.
7609 2004-11-13 Stepan Kasal <kasal@ucw.cz>
7611 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
7612 the $1_found variable, don't test whether the file is executable;
7613 Both things are checked ...
7614 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
7615 the former ``test -f''.

7630 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
7631 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
7632 variants", "Unix", and some related minor wording fixups.
7634 (Shellology, Special Shell Variables): Document that the Zsh
7635 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
7636 to Alexandre Duret-Lutz for this info.

7645 of putenv. Problem reported by Michael Wardle.
7647 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
7649 * doc/autoconf.texi (auindex): New macro.
7650 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
7651 Problem reported by Stepan Kasal.
7653 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
7655 Fix problems reported by Andreas Buening in:
7656 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
7657 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
7659 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
7660 readable; it's not true in OS/2-emx.
7662 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
7664 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
7665 "/usr/include", clear ac_x_includes instead of leaving it as "no"
7666 (trivial change). Problem and patch reported by Andrew Church in:
7667 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
7669 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

7696 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
7697 texinfo.tex for now (done by hand now).
7698 * Makefile.maint (wget_files, cvs_files):
7699 Remove ansi2knr.c; nobody uses it.
7700 (ansi2knr.c-url_prefix): Remove.
7701 (cvs-update): Fix test for failure. I don't know why it ever
7704 * doc/autoconf.texi: Update URLs, some of which went stale.
7705 Use @uref rather than @href.
7707 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
7708 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
7710 * config/config.guess, config/config.sub, config/elisp-comp,
7711 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
7712 doc/fdl.texi, doc/standards.texi: Sync with master copy.

7722 Use "file name" rather than "filename" or "path",
7723 to be consistent with the terminology of the GNU coding standards.
7725 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
7727 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
7728 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
7729 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
7730 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
7732 More fixes to support spaces in the name of the build directory.
7733 This isn't a complete fix but it's an improvement.
7735 * bin/autoconf.as (autom4te_options): New var.
7736 Use it instead of appending to AUTOM4TE, so that we can allow
7737 spaces in the build directory's absolute name.
7738 * bin/autoheader.in ($autoconf): Allow spaces in file names.
7739 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
7740 AT_CHECK_NOESCAPE): Likewise.
7741 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
7742 main program): Likewise.
7744 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
7746 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

7752 * doc/autoconf.texi (Function Portability): Document isinf and
7753 and isnan. From a suggestion by Kevin Ryde.
7755 * lib/Autom4te/General.pm (END): Return correct exit status even
7756 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
7758 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
7760 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
7761 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
7762 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
7764 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
7766 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
7767 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
7768 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
7769 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
7770 * lib/autom4te.in (Automake-preselections): Preselect
7771 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
7773 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
7775 * lib/autom4te.in (Automake-preselections): Preselect
7776 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
7779 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
7781 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
7783 * doc/autoconf.texi (Shellology): Mention BIN_SH.
7784 Document problem with "`""`" in pdksh POSIX mode.
7786 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
7788 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
7789 with pdksh, too. Problem reported by Patrick Welche via
7791 * doc/autoconf.texi (Shellology): Note that set -o posix is
7792 useful for pkdsh, too.
7794 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
7796 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
7797 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
7798 Don't fail if ENV or BASH_ENV is readonly.
7799 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
7800 etc. are read only. Problem reported by Ludovic Courtes.
7802 2004-06-23 Noah Misch <noah@cs.caltech.edu>
7804 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
7805 zsh, disable GLOB_SUBST to avoid backslash handling problems.
7808 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
7810 * doc/autoconf.texi (File System Conventions): Warn about
7811 names like "aux". Problem reported by Eric Blake.
7813 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
7814 by zero instead of array size, so that we can use any arithmetic
7815 constant expression (instead of requiring an integer constant
7816 expression). This allows us to test expressions like DBL_MAX <
7817 LDBL_MAX, which didn't conform to the C standard using the old
7819 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
7820 now that we can do floating-point tests at compile time.
7822 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
7824 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
7825 and LDBL_EPSILON, as the resulting expression isn't an
7826 integer constant expression and violates the C standard.
7827 Problem reported by Nelson H. F. Beebe. Also, check
7828 for "L" suffix, and check that long double doesn't have
7829 worse range or precision than double, that mixed-mode
7830 arithmetic doesn't generate a diagnostic, that double
7831 constants fit in long double.
7833 2004-06-03 Kevin Ryde <user42@zip.com.au>
7835 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
7836 malloc(0) and realloc(NULL,size).
7838 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
7841 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
7843 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
7844 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
7847 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
7849 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
7850 can be rewritten using if-then-else. Suggested by Bruno Haible.
7852 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
7854 * doc/autoconf.texi (testsuite Scripts): Fix typo.
7855 Problem reported by Stepan Kasal.
7857 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
7859 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
7860 change). Patch reported by Ralf Wildenhues in
7861 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
7863 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
7864 function F exists if the compiler and linker let you compile an
7865 expression like (F != 0). Recent versions of GCC optimize away
7866 the reference to F in that case, since every function address must
7867 be nonzero, so the link succeeds even if F does not exist.
7868 Problem reported by Manu in
7869 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
7871 * doc/autoconf.texi (Systemology): Standardize on the spelling of
7872 "Unix". Many uses changed.
7873 (Limitations of Builtins): Explain better why the ! command isn't
7876 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
7878 * lib/autom4te.in (Automake-preselections): Preselect
7879 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
7881 2004-05-19 Kevin Ryde <user42@zip.com.au>
7883 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
7884 referencing AC_FUNC_STRERROR_R.
7886 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
7887 note pessimistic assumption when cross compiling.
7889 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
7891 * doc/autoconf.texi (Limitations of Make): Note that BSD make
7892 (until 2004) invoked subcommands with sh -e, contra POSIX.
7893 Reported by Kevin Ryde.
7895 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
7897 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
7898 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
7899 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
7900 `test -f " /usr/bin/grep"', which _always_ failed.
7901 (AC_PROG_SED): Ditto bogus PATH fix.
7902 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
7903 requires that grep correctly supports _multiple_ `-e' options, rather
7904 than stating only that grep should accept `-e'.
7906 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
7908 Port to C99, which requires that 'exit' be declared.
7910 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
7911 to ensure that stdlib.h is included.
7912 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
7913 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
7914 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
7915 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
7916 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
7917 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
7918 when using 'exit' in a test; C99 requires that 'exit' be declared.
7920 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
7922 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
7923 now prefers 'grep' implementations that accept -e.
7924 (Limitations of Usual Tools): Describe problems of traditional
7925 egrep and fgrep with long input lines, and of traditional grep
7927 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
7928 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
7929 All callers changed. Append /usr/xpg4/bin to the PATH, for
7931 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
7932 the user with complaints about multiple -e options.
7933 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
7934 Define it with AC_PROG_GREP.
7935 * configure.ac (AC_PROG_GREP): Add.
7936 * lib/freeze.mk (GREP): New macro.
7938 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
7940 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
7941 a possible candidate only after all others fail, rather than
7942 consulting it first. This improves backward compatibility by
7943 better reflecting the way shell selection occurred in previous
7944 versions of Autoconf, and should help to avoid triggering latent
7945 problems in other packages, such as the one in Automake where zsh
7946 is not handled robustly:
7947 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7948 Although it is not Autoconf's responsibility to work around
7949 problems in Automake, it nevertheless makes sense to avoid
7950 introducing unnecessary incompatibilites.
7952 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7953 Gary V. Vaughan <gary@gnu.org>
7955 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7956 how deeply nested we are when a suitable tool is found, set the
7957 ac_path_TOOL_found flag.
7958 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7959 nested we are in this macro. Break out of all 3 nested loops if
7960 ac_path_TOOL_found is set.
7962 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7964 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7965 of the _AS_PATH_WALK loop too if GNU flavor is found.
7967 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7969 * doc/autoconf.texi (Limitations of Make): Update documentation
7970 for `$<'. New entry `Long lines', based on a report from Simon
7971 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7972 paragraph about DJGPP, based on a mail from Richard Dawe.
7974 2004-04-20 Paul Eggert <eggert@twinsun.com>
7976 * tests/c.at (C keywords): Don't assume that GCC supports
7977 "restrict" and "inline", as sufficiently-old GCC versions do not
7978 (also, GCC configured to be in pedantic C89 mode does not).
7979 Problem reported by Sumit Pandya in:
7980 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7982 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7983 consider -g to work if it generates warnings when plain compiles
7984 don't. Problem reported by Braden McDaniel in:
7985 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7987 * doc/autoconf.texi (Slashes): New section, to document a problem
7988 reported by Jim Meyering in:
7989 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7991 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7992 linker output files before linking, to work around IRIX 6 linker bug.
7993 Problem reported by Rainer Orth in:
7994 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7996 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7998 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7999 best tool so far counter rely on the tool path variable name to
8000 avoid checks for one tool being affected by the results of running
8001 the length check on a previous tool.
8003 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional

8141 AC_SUBST provides no portable way to escape literal newlines.
8143 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
8144 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
8145 Darwin uses -lcrt2.o and there's little point to cataloging all

8222 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
8223 2003 (except 1997) to the list of copyright years. This undoes
8224 the 2003-05-22 change, which removed the older years from the list.
8225 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

8238 _AC_PROG_GREP, and AC_PROG_SED.

8271 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
8272 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
8273 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
8274 not <inttypes.h>. Problem reported by Tim Mooney in

8276 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
8279 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
8280 otherwise "make check" fails because it forbids cmp (I guess
8281 because cmp treats files as binary on DOS-like systems).

8296 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
8297 -std1 disables some useful extensions on Tru64. Problem reported

8303 * doc/autoconf.texi (Programming in M4sh): Document that
8304 AS_MKDIR_P succeeds if the destination is a symbolic link
8305 to an existing directory.
8306 (Limitations of Usual Tools): Note that mkdir -p might not
8307 succeed on symlinks to directories.

8327 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
8328 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
8329 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
8330 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
8331 AC_COMPILE_IFELSE, since we now assume our caller invokes
8332 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
8333 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
8334 of AC_RUN_IFELSE; this avoids the warning mentioned above.
8335 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
8337 2004-01-07 Paul Eggert <eggert@twinsun.com>
8339 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
8340 `"'...'"`, as it's confusing (and I suspect it may not work on
8341 some platforms). The code was incorrect anyway, as it assumed
8342 that \$ evaluated to itself in that context. Reported by
8343 Alexandre Duret-Lutz.
8345 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
8347 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

8377 Bug reported by David Relson in
8378 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
8380 * Makefile.am (autom4te-update):
8381 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

8397 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
8398 -c -o might not work. From a suggestion by Kevin Ryde.
8399 (C Compiler, Generating Sources, Limitations
8400 of Usual Tools, Limitations of Make, Making testsuite Scripts):
8401 Don't put '-o' after non-options, as POSIX doesn't allow this.
8402 Mention that cc's name might be gcc or c89 or whatever.
8404 2004-01-04 Kevin Ryde <user42@zip.com.au>

8413 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
8415 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
8416 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
8417 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
8418 explanation clearer.

8699 Problems reported by Eric Sunshine.
8701 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
8703 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
8704 -mGLOB_options_string stuff for Intel ifc, which can cause
8705 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
8706 pattern-matching instead of grep.

8726 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
8728 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
8729 cache variable instead of $G77 to decide whether to include -O2,
8730 since $G77 is specific to Fortran 77.
8732 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8734 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
8735 free" flag. Re-order flags tested into rough order of popularity.
8737 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
8739 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
8740 arguments so that it can be used with syntax identical to
8741 AC_PROG_F77, and so that we can more easily decide to
8742 remove/deprecate the DIALECT optional argument in the future if it
8744 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
8745 non-freeform-supporting compilers. Document freeform flags.

8808 Problem reported by Lars J. Aas in
8809 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
8810 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
8811 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

8814 2003-09-26 Akim Demaille <akim@epita.fr>
8816 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
8817 directory for AC_CONFIG_COMMANDS' first argument exists.
8818 This makes valid the invocation of _AC_SRCPATH that follows.
8819 Reported by Eric Sunshine.
8820 * doc/autoconf.texi (Configuration Commands): Adjust.
8822 2003-09-26 Akim Demaille <akim@epita.fr>

8843 The test suite are sometimes assigning timings incorrectly.
8844 Reported by Henk Krus.
8845 Diagnosed by Nicolas Joly.
8847 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
8849 Instead of making AT_help a sequence of assignments to grow
8850 $at_help_all, just make AT_help_all be the growing contents of
8851 $at_help_all, and make a single assignment in...
8853 (at_times_skip): Flip the meaning and rename as...
8855 (AT_INIT): When summarizing the test that ran, remove
8856 $at_times_file after use, and check it is present before trying to

8863 * bin/Makefile.am (edit): Handle '@configure_input@'.
8864 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
8865 (ifnames): chmod -w.
8866 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
8867 executables, not bin/ executables! Otherwise all the magic needed
8868 to find non installed files is turned off. This caused a failure
8869 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
8870 as found in its environment (sent by tests/autoreconf): pointing
8871 to bin/autom4te that could not find its files.
8872 * tests/mktests.sh: Force the replacement of generated files, for
8873 the sake of "mv" program that are interactive when overwriting a
8875 * config/install-sh: Upgrade from CVS Automake.
8877 2003-09-23 Paul Eggert <eggert@twinsun.com>

8880 versus test -L issues.
8882 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and

8920 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
8921 willing to edit the output files.
8923 2003-09-10 Akim Demaille <akim@epita.fr>

8966 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8968 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8970 Add support for newer Fortran dialects. The F77 interface is
8971 unchanged, and continues to support Fortran 77. New FC macros
8972 correspond to all the old F77 macros, with output variables FC,
8973 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8974 available dialect, but older dialects can be specified. There are
8975 new macros AC_FC_SRCEXT to set the source extension, and
8976 AC_FC_FREEFORM to accept free-form source files.
8978 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

9102 2003-08-21 Akim Demaille <akim@epita.fr>
9104 First stab at preserving warnings between calls to autom4te,
9105 including when the cache is used.
9107 There are still several issues: (i) there are too many runs of m4
9108 (one for include, one for warnings, and some more), (ii) warnings
9109 spreading on several lines are not handled gracefully, (iii) the
9110 code meant to have the call stack display for errors does not work
9111 (its handling should move from m4 to autom4te).
9113 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
9115 (@preselect): Add m4_warn.
9116 ($exit_status): Remove, use $exit_code.
9117 ($help): Use Autom4te::ChannelDefs::usage.
9118 (&handle_m4): No longer define the m4_warnings.
9119 At each run, extract and report the warnings.
9120 Always cache the result, including if the exit status is on
9121 failure, since if nothing changes, we should result in the same
9122 failure, hence we can use the cache.
9123 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
9124 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
9126 (m4_warn): Redefine as a do-nothing: it is its invocation that
9127 matters, as warnings are now reported via traces.
9128 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
9129 the contents of m4_warn: make it _call_ m4_warn, so that tracing
9130 the latter reveals calls to the former.
9134 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

9163 Reported by Alexandre Duret-Lutz.
9165 2003-08-20 Akim Demaille <akim@epita.fr>
9167 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
9168 * bin/autom4te: Adjust.
9169 In particular, be Autoconf tools are really silent when properly
9170 working, bind the verbosity of the 'note' channel to $verbose.
9171 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

9235 shorter column three. Add DESCRIPTION to log file content.

9295 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
9296 not all of them. This fixes 1. the fact that when testing
9297 Autoconf there are many many config.log, 2. the incorrect use of
9298 top_srcdir to find config.log.
9299 Don't mix the detailed output of failed test with the summary of
9300 failures. Rather, append detailed log afterwards.

9419 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
9420 Remove `#include <stdlib.h>' from the list; we should never
9421 make confdefs.h include <stdlib.h> or <cstdlib>, because the
9422 resulting namespace pollution would cause other tests to fail.
9423 Configure scripts run with some older versions of g++ and HP's
9424 aCC would fail due to such an #include. Problems reported by
9425 Matthew Mueller in <http://bugs.debian.org/120704> and by
9427 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
9428 In the test, use the test declaration before including <stdlib.h>,

9438 Overhaul Autotest's logging: generate separate log files
9439 in testsuite.dir/NNN/testsuite.log, and append them to
9440 testsuite.log instead of re-running the test verbosely.
9442 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
9443 file descriptor, write 0 to at_status_file instead of setting
9444 at_status=0, initialize some new variables (at_status_file,
9445 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
9446 to rerun the tests, instead append the at_group_log to the
9447 at_suite_log when a test fails.
9448 (AT_SETUP): pipe the test case's output into at_tee_pipe,
9449 with the AS_MESSAGE_LOG_FD redirected to stdout.
9450 (AT_CLEANUP): save the output status in $at_status_file
9451 and restore it, redirect the AS_MESSAGE_LOG_FD back to
9453 (AT_CHECK): since tests are run with a redirected stdout,
9454 and used to be re-run in verbose mode, turn some $at_verbose
9455 into echo, and don't redirect the output of testing stdout
9458 * lib/autotest/autoconf.texi (testsuite Scripts): Update

9579 2003-05-06 Akim Demaille <akim@epita.fr>
9581 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
9582 longer updates aclocal.m4 if useless, (ii) if a file m4_included
9583 by aclocal.m4 is changed it might require the importing of another
9584 m4 extension file, i.e., aclocal must be run.
9586 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
9587 (&parse_args): Use --force with aclocal if required and supported.

9605 (AT_CLEANUP): Add `;' to end of at_help_all.
9606 (AT_INIT): Allow --keywords to be specified more than once. When

9704 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
9705 use new diversions in preparation for accepting new arguments and

9760 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
9761 Tru64 make in the "target lookup" section.
9762 (Automake): Automake 1.5+ no longer requires special tools to be
9763 present on the developer's host.
9765 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
9767 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
9768 to a shell that can handle redirection or quoting correctly.
9769 Override SHELL with the shell detected by configure.
9770 Use of $^O suggested by Tim van Holder.
9771 * bin/autom4te.in (BEGIN): Likewise.
9772 * bin/autoreconf.in (BEGIN): Likewise.

9803 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
9804 to fix a mismatch between example and discussion.
9806 2003-02-24 Kevin Ryde <user42@zip.com.au>
9808 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
9809 format starting with "-".
9811 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

9818 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
9819 compiler says yeah, but preproc says nope, compiler is right.
9820 Conversely, prompt the reader to send a bug report to the
9821 maintainers of the package, not of Autoconf.
9823 2003-02-20 Klee Dienes <kdienes@apple.com>
9825 * bin/autoreconf.in (autoreconf_current_directory): Properly

9834 2002-12-23 Paul Eggert <eggert@twinsun.com>
9836 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
9837 innocuous variant befor including <limits.h> or <assert.h>. This
9838 works around a bug reported by Albert Chin: HP-UX 11i
9839 (and earlier versions) have a <limits.h> that declares
9840 gettimeofday and many other functions.
9842 2002-12-03 Paul Eggert <eggert@twinsun.com>
9846 * NEWS, configure.ac: Update version.
9848 * doc/fdl.texi: Upgrade to FDL version 1.2.
9850 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
9851 nontrivially in main's body, so that f's external declaration is
9852 not optimized away in AIX. This should fix the bug reported by
9854 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
9856 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
9857 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
9858 defined, to support freestanding compilers. This should fix the
9859 bug reported by Momchil Velkov in
9860 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
9862 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
9863 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
9864 obsolete AC_CHECK_TYPE. The missing empty arg was reported
9865 by Simon Josefsson in

9894 Update from masters.
9896 2002-11-14 Akim Demaille <akim@epita.fr>
9898 * Makefile.maint: Sync with Bison, i.e.:
9899 (po-check): Scan .l and .y files instead of the
9900 .c and the .h files that they generate. This fixes the bug
9901 reported by Tim Van Holder in:
9902 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
9903 Look for N_ as well as for _. Try to avoid matching #define for
9907 2002-11-14 Akim Demaille <akim@epita.fr>
9909 * doc/autoconf.texi (C Compiler): Compiling several files at once.
9910 From Paul Eggert and Albert Chin-A-Young.
9912 2002-11-14 Akim Demaille <akim@epita.fr>
9914 * doc/autoconf.texi (C Compiler): Solitary backslashes.
9915 From Paul Eggert and Albert Chin-A-Young.
9917 2002-11-14 Kevin Ryde <user42@zip.com.au>
9919 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
9920 than assigning in main, to avoid HP cc +O3 optimizing it away.
9922 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
9924 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
9925 option. Process --recheck after parsing all options. Pass -q
9926 option to configure on --recheck.
9927 (AC_OUTPUT): Pass -q from configure to config.status.
9928 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
9929 arguments to record.
9930 * doc/autoconf.texi (config.status Invocation): Document
9931 config.status -q option.
9933 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
9935 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore

9949 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9950 declaration in extern "C" too.
9951 Reported by Roberto Bagnara.

9955 * tests/torture.at (Configuring subdirectories): Don't use grep
9957 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9958 Reported by Ezra Peisach.
9960 2002-11-05 Akim Demaille <akim@epita.fr>
9962 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9964 We _have_ to stop using the old compatibility scheme that tried to
9965 avoid useless backslashes because Libtool 1.4.3 contains a
9966 AC_DEFINE([error_t], [int],
9967 [Define to a type to use for \`error_t' if it is not
9968 otherwise available.])
9969 We _have_ to quote the single quote and backslashes with \. The
9970 old compatibility scheme saw that ` was backslashed, and therefore
9971 did not quote the single quote. Hence before this patch, Autoconf
9972 was not compatible with Libtool.
9974 2002-11-04 Paul Eggert <eggert@twinsun.com>
9976 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

9987 * config/texinfo.tex: Update.
9989 2002-11-03 Akim Demaille <akim@epita.fr>
9991 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9993 (&autoreconf): here.
9994 ($help, $make, &parse_args, &autoreconf_current_directory):

10363 Reported by Alexandre Duret-Lutz.
10365 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

10385 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
10386 if some file was changed instead of `print'.
10387 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

10421 file name to enable parallel executions.
10422 From Sam Varshavchik.
10424 2002-10-08 Akim Demaille <akim@epita.fr>
10426 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
10427 aclocal invocation, as Gettext macros might not be visible to
10429 Instead of blindly running autopoint, scan configure.ac (not the
10430 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
10431 Reported by Paul D. Smith.
10433 2002-10-08 Paul Eggert <eggert@twinsun.com>
10435 Work around problems found when POSIXLY_CORRECT=1 is set.
10436 None of this seems to have anything to do with POSIX, really,
10437 but it's how Perl getopt works.
10438 * bin/autom4te.in (parse_args): Configure GetOpt with
10440 * doc/autoconf.texi (Invoking autom4te):
10441 --warning -> --warnings.

10463 * tests/torture.at (Configuring subdirectories): Be robust to
10464 users who use config.site to require for a cache: in this case,
10465 the two last configure runs, using two different sets of
10466 arguments, trigger a legitimate error.
10468 2002-09-28 Akim Demaille <akim@epita.fr>

10501 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
10502 (.m4.m4f): Don't pass --prepend-include, since that's done by
10503 tests/autom4te itself.
10504 * lib/autoscan/Makefile.am: Include freeze.mk.
10505 (autoscan.list): New target --this file is no longer a source.
10506 (autoscan.pre): New file.
10508 2002-09-28 Akim Demaille <akim@epita.fr>
10510 * bin/autoscan.in (@kinds): Make them singular.
10512 (&init_tables): When --debug, report the list of rules to ease
10513 tracking changes in autoscan.list.
10514 * lib/autoscan/autoscan.list (function): Strip comments, sort.
10516 2002-09-28 Akim Demaille <akim@epita.fr>

10522 * bin/autoscan.in (&init_tables): Adjust.
10524 2002-09-28 Akim Demaille <akim@epita.fr>
10526 * lib/autoscan/functions, lib/autoscan/headers,
10527 * lib/autoscan/identifiers, lib/autoscan/makevars,
10528 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
10529 `functions' line is now prefixed with `function:'.
10530 * bin/autoscan.in (&init_tables): Adjust.
10532 2002-09-28 Akim Demaille <akim@epita.fr>
10534 From now on, autoscan files must always map a macro name to a
10535 word: there is no `default' macro for autoscan.
10537 * bin/autoscan.in (&init_tables): Reject entries with no macro at
10539 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
10542 2002-09-28 Akim Demaille <akim@epita.fr>
10544 * bin/autoscan.in (%c_keywords): Remove.
10545 (&used): Keep only track of the words we might be interested in.
10546 (&output_kind): It is no longer needed to look for non active

10560 Thanks to Bill Moseley and Paul Eggert.
10561 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
10562 the tmpdir must be created.
10563 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
10564 dir be in the build tree, instead of $TMPDIR.
10566 2002-09-27 Akim Demaille <akim@epita.fr>
10568 * bin/autoscan.in: Improve the comments.
10569 (&parse_args): Drop obsolete undocumented options.

10578 * doc/autoconf.texi (autoreconf Invocation): Likewise.
10580 2002-09-26 Akim Demaille <akim@epita.fr>
10582 Single suffix rules and seperated dependencies are not portable.
10584 * doc/autoconf.texi (Installation Directory Variables): Update.
10585 (Limitations of Make): Some about `Single Suffix Rules and
10586 Separated Dependencies'.
10587 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10588 (ifnames, autoscan, autom4te): Un-factor into several rules.
10590 2002-09-25 Paul Eggert <eggert@twinsun.com>
10592 * BUGS (Interoperability bugs): New section. Mention libtool
10593 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
10595 2002-09-24 Paul Eggert <eggert@twinsun.com>
10597 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
10598 make handles suffix-rules differently from GNU make.
10600 * bin/Makefile.am (SUFFIXES, .in): Remove.
10601 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
10602 Move the body of the old .in rule here.
10604 2002-09-16 Akim Demaille <akim@epita.fr>
10606 i960 compilers create `b.out' files by default.
10607 Reported by Ralf Corsepius.
10609 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
10610 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
10612 2002-09-13 Paul Eggert <eggert@twinsun.com>
10614 * doc/autoconf.texi (Particular Headers): Remove obsolete
10615 reference to `struct timezone' in the description of

10623 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
10624 * Makefile.am: Adjust.
10626 2002-09-13 Akim Demaille <akim@epita.fr>
10628 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
10629 reading config.log when the compiler is rejected.
10630 Suggested by Guido Draheim.
10632 2002-09-13 Akim Demaille <akim@epita.fr>
10634 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
10635 (chdir_init) might hang when stat'ing mounted directories.
10636 Reported by Vance Shipley.
10638 2002-09-12 Akim Demaille <akim@epita.fr>
10640 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
10643 2002-09-12 Akim Demaille <akim@epita.fr>
10645 * doc/autoconf.texi (Defining Symbols): Present two different
10646 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
10647 difference between 1 argument calls, and 2-3 argument calls.
10649 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
10651 * doc/autoconf.texi: Review grammar and punctuation.
10653 2002-09-11 Paul Eggert <eggert@twinsun.com>
10655 * doc/autoconf.texi: Fix minor formatting, spelling, and
10657 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
10658 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
10661 2002-09-11 Akim Demaille <akim@epita.fr>
10663 * doc/autoconf.texi (Questions): Rename as...
10665 (Defining Directories): New.
10667 2002-09-09 Akim Demaille <akim@epita.fr>
10669 * doc/autoconf.texi (Making testsuite Scripts): Update.
10670 Suggested by Nishio Futoshi.
10672 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
10674 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
10675 plain `@' is wanted.
10677 2002-09-09 Akim Demaille <akim@epita.fr>
10679 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
10680 `duplicates', since the algorithm was too naive and could keep
10681 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
10682 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
10683 Reported by Ralf Corsepius.
10684 * tests/torture.at (Configuring subdirectories): Exercise these
10687 2002-09-09 Akim Demaille <akim@epita.fr>
10689 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
10690 looking for a replacement file.
10691 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
10692 directory is relative.
10693 * doc/autoconf.texi (Generic Functions): Clarify the replacement
10694 directory definition.
10695 Reported by Andreas Schwab and Jim Meyering.
10697 2002-09-06 Akim Demaille <akim@epita.fr>
10699 * doc/autoconf.texi (Setting Output Variables): Clarify what
10700 precious variables are.
10701 Suggested by Pontus Skoeld.
10703 2002-09-05 Akim Demaille <akim@epita.fr>
10705 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
10706 (ifnames, autoscan, autom4te): Since we don't only depend on
10707 configure.ac variables (such as VERSION etc.), but also on prefix
10708 and so forth, depend on Makefile, not configure.ac.
10709 Reported by Alexandre Duret-Lutz.
10710 * doc/autoconf.texi (Installation Directory Variables): Adjust.
10712 2002-09-05 Kevin Ryde <user42@zip.com.au>
10714 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
10715 doesn't seem to be confined to ia64, just say "some versions".
10717 2002-09-04 Akim Demaille <akim@epita.fr>
10719 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
10721 * Makefile.am (maintainer-clean-local): Remove.
10722 (MAINTAINERCLEANFILES): Remove COPYING.
10724 2002-09-03 Paul Eggert <eggert@twinsun.com>
10726 * doc/autoconf.texi (Configuration Commands): Remove obsolete
10727 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
10730 2002-09-03 Akim Demaille <akim@epita.fr>
10732 * configure.ac: Bump to 2.53d.
10733 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
10734 as of today, on Automake's team suggestion.
10736 2002-09-03 Akim Demaille <akim@epita.fr>
10740 2002-09-02 Akim Demaille <akim@epita.fr>
10742 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
10744 * configure.ac: Disable SITE_MACRO_DIR.
10746 2002-09-02 Jim Meyering <meyering@lucent.com>
10748 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
10749 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
10750 Also, tweak grammar: s/make sure to/be sure to/.
10752 2002-09-02 Paul Eggert <eggert@twinsun.com>
10754 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
10755 directory names are generally preferable to physical names.
10757 2002-09-02 Akim Demaille <akim@epita.fr>
10759 * lib/Autom4te/General.pm (&update_file): s/die/error/.
10760 Reported by Raja R. Harinath.
10761 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
10762 * bin/autoupdate.in: Use error instead of die.
10764 2002-09-01 Paul Eggert <eggert@twinsun.com>
10766 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
10767 ordinary shell concatenation rather than echo+tr+sed command that
10768 runs afoul of a long-line-related sed bug in Solaris 8.
10770 * bin/autoheader.in (parse_args): --warning -> --warnings.
10772 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
10773 stdout, as traditional "ls" does.
10774 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
10775 _AC_COMPILER_EXEEXT_O): Likewise.
10776 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
10778 * bin/autoconf.as: Add --prepend-include option. This patch was
10779 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
10780 but bin/autoconf.in is generated automatically from bin/autoconf.as.
10782 * bin/autoconf.in, configure: Regenerate.
10784 * doc/autoconf.texi (Special Shell Variables): Mention
10785 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
10787 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
10788 MAILPATH and set PS1, PS2, PS4 to default values, to work
10789 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
10790 For LC_ALL etc, first try to set to "C" as POSIX requires and as
10791 the Autoconf documentation specifies; fall back to "unset" only if
10792 this fails. Use a shell for-loop for this rather than an m4 loop,
10793 to shorten the output script.
10795 2002-08-30 Paul Eggert <eggert@twinsun.com>
10797 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
10798 1003.1-2001's requirements for CDPATH. Give a simpler workaround
10799 for the CDPATH problem. Document PWD.
10800 (Limitations of Builtins): Document the problem that "cd $foo" and
10801 "ls $foo" may refer to different directories in shells conforming
10802 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
10803 example, since the old example is now out of date.
10805 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
10806 FOO" and "ls FOO" talk about different directories; this catches
10807 problems when POSIX 1003.1-2001 "cd" fails due to symlink
10810 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
10811 of rolling our own unset.
10812 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
10813 in practice we needn't worry about CDPATH if unset doesn't work.
10815 * Makefile.in, aclocal.m4, bin/Makefile.in,
10816 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
10817 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
10818 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
10819 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
10820 tests/Makefile.in: Regenerate with Automake 1.6.3.
10822 * config/config.guess, config/config.sub, config/mkinstalldirs:
10825 * configure: Regenerate with self.
10827 2002-08-30 Kevin Ryde <user42@zip.com.au>
10829 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
10832 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
10834 * bin/autom4te.in (Request::load): Correctly test for "do" read
10837 2002-08-29 Akim Demaille <akim@epita.fr>
10839 * lib/Autom4te/General.pm (&xqx): New.
10840 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
10841 hand, which is not portable.
10843 * bin/autom4te.in: Use them.
10844 Use &error instead of die.
10845 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
10848 2002-08-17 Paul Eggert <eggert@twinsun.com>
10850 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
10851 default list of compilers to try, since it was long ago superseded
10852 by the ksh fc builtin. Suggested by Steven G. Johnson.
10854 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
10856 * doc/autoconf.texi (Invoking autom4te): End the option table,
10857 fixing a bug introduced by the previous patch.
10858 (Limitations of Make): Add a 'target lookup' subentry in the
10859 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
10861 2002-07-29 Mark D. Roth <roth@feep.net>
10863 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
10864 options and use $AUTOM4TE_PATH.
10865 * doc/autoconf.texi: Remove documentation of autom4te
10866 --include-envvar and --site-macro-subdir options and document
10867 use of $AUTOM4TE_PATH.
10868 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
10869 arguments from each language section.
10871 2002-07-29 Paul Eggert <eggert@twinsun.com>
10873 * doc/install.texi: Include copyright symbol in copyright notice.
10875 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
10877 (AM_MAKEINFOFLAGS): New macro.
10878 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
10879 * Makefile.am (INSTALL): Use the new macros.
10880 Use -o rather than --output, since "missing" does not grok --output.
10882 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10884 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
10885 comments do not always work. Never trust the exit status of
10888 2002-07-24 Kevin Ryde <user42@zip.com.au>
10890 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
10891 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
10893 2002-07-23 Paul Eggert <eggert@twinsun.com>
10895 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
10896 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
10897 apparently treats PATH="nonexistent" as if it contained ".".
10898 Bug reported by Stefan `Sec' Zehl.
10900 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10902 * doc/autoconf.texi (Limitations of Make): Mention the special
10903 handling of the obj/ directory by BSD make.
10905 2002-07-20 Kevin Ryde <user42@zip.com.au>

10937 Alexandre Duret-Lutz <duret_g@epita.fr>
10939 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
10940 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
10942 2002-07-17 Russ Allbery <rra@stanford.edu>

10945 description of the tarname default.
10947 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
10949 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10950 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10951 latter was not run.
10953 2002-07-17 Akim Demaille <akim@epita.fr>
10955 * lib/Autom4te/General.pm (find_file): Browse the directories in
10956 the order they are given.
10958 2002-07-17 Akim Demaille <akim@epita.fr>
10960 * tests/wrapsh.as, tests/wrappl.as: Merge into...
10961 * tests/wrapper.as: this.
10962 * tests/Makefile.am, configure.ac: Adjust.
10964 2002-07-17 Mark D. Roth <roth@feep.net>
10966 * configure.ac: Add --enable-site-macro-dir option.
10967 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
10968 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
10969 --site-macro-subdir options.
10970 * bin/autoconf.in: Add --prepend-include option.
10971 * bin/autoheader.in: Add --prepend-include option.

10974 * bin/autoupdate.in: Add --prepend-include option.
10975 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
10976 macro directory, remove note that include path directories are
10977 used in reverse order, and document --prepend-include option.
10978 * lib/autom4te.in: Use --prepend-include instead of --include.
10979 * tests/wrapsh.in: Use --prepend-include instead of --include.

11024 2002-06-27 Paul Eggert <eggert@twinsun.com>

11168 This improves on an earlier suggestion by H. Peter Anvin.
11170 2002-05-16 Paul Eggert <eggert@twinsun.com>
11172 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
11173 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
11174 Both macros now accept an optional source-dir arg.
11175 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
11177 * NEWS: Document this.
11178 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
11180 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
11181 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
11182 not for GNU extensions; this undoes part of the 2000-11-03 change,
11183 reverting to 2.13-compatible behavior.
11184 Add new optional argument DIR.
11185 (AC_FUNC_FNMATCH_GNU): New macro.

11191 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
11192 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
11193 and it causes a 'test' syntax error if it fails.
11194 Bug reported by Stephen Gildea.
11196 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
11197 If prototypes are supported, use them to check this at compile-time,
11198 instead of trying to check it at run-time. If we must do a run-time
11199 check, assume that setvbuf is standard when cross-compiling, as
11200 nonstandard setvbuf occurs only on ancient and unlikely hosts.
11201 Bug reported by Paul D. Smith.
11203 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
11204 argument specifying location of getloadavg.c. This removes a
11205 FIXME. This idea was taken from Jim Meyering's implementation in
11207 * doc/autoconf.texi (Particular Functions): Document this.
11208 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
11209 that's what the code does; this fixes a bug reported by
11212 2002-05-03 Akim Demaille <akim@epita.fr>
11214 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
11215 autopoint instead of gettextize.
11216 ($uses_alocal): Rename as...
11217 ($uses_aclocal): this.
11218 * doc/autoconf.texi (autoreconf Invocation): Adjust.
11219 Suggested by Bruno Haible.
11221 2002-05-03 Akim Demaille <akim@epita.fr>
11223 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
11225 2002-04-29 Paul Eggert <eggert@twinsun.com>
11227 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
11228 files to be 1 second older; just set them to be the same time.
11229 Also, sleep 1 second after the first aclocal, to work around
11230 problems with sub-second time stamps on the input files.
11232 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
11234 * doc/autoconf.texi: Mention "set -e -x" lossage
11235 under node "Limitations of Builtins".

11241 From Christian Cornelssen.
11243 2002-04-29 Akim Demaille <akim@epita.fr>
11245 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
11246 of lack of $LINENO support, then the test will compare the $LINENO
11247 in testsuite vs. the lineno in the test file. This is wrong, of
11249 Be sure to protect it.
11250 Reported by Patrick Welche.
11252 2002-04-25 Akim Demaille <akim@epita.fr>
11254 * doc/autoconf.texi (Obsolete Macros): Typo.
11255 Reported by Vladimir Volovich.
11257 2002-04-25 Akim Demaille <akim@epita.fr>
11259 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
11260 than some of the input files, hence, on the second run of aclocal,
11261 if some of its input are younger, make them older.
11262 Suggested by Paul Eggert.
11264 2002-04-25 Akim Demaille <akim@epita.fr>
11266 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

11272 and ac_subst_vars be sh variables containing the list of
11273 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
11275 (_AC_INIT_PREPARE): Use them to log them.
11276 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
11277 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
11278 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
11279 _AC_SUBST_FILES and _AC_SUBST_VARS.
11280 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
11282 2002-04-24 Akim Demaille <akim@epita.fr>
11284 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
11285 autoheader, so that automake does not complain about a missing
11286 config.h.in that was to be created.
11288 2002-04-23 Akim Demaille <akim@epita.fr>

11344 importantly, this makes sure that the copyright notices appear in

11474 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
11475 (_AC_COMPILER_OBJEXT): Use them.
11476 Fixes Debian #138666.
11478 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
11480 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
11482 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
11483 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
11484 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
11485 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
11486 (AC_C_CONST): Same.

11498 2002-03-28 Kevin Ryde <user42@zip.com.au>
11500 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
11501 to avoid versions of HP C which don't allow that.
11503 2002-03-27 Paul Eggert <eggert@twinsun.com>
11505 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

11517 2002-03-25 Paul Eggert <eggert@twinsun.com>
11519 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
11520 as POSIX requires, as it doesn't work with Zsh.
11521 * doc/autoconf.texi (Assignments): Document the problem.
11523 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

11526 about VPATH, overriding of macros in sub-makes, and handling of

11531 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
11532 problem with here-document buffer boundaries.
11534 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
11535 when reinvoking the shell, to work around problems with installers
11536 who put strange things like "cd" commands in their environments.

11561 (Limitations of Usual Tools): Add mkdir section.
11563 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
11564 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
11565 back on AS_DIRNAME to compute prefixes otherwise; this is
11566 roughly what mkinstalldirs does. That way, we need not have
11567 our own filename disassembler. The old disassembler did not
11568 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
11570 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
11571 Create at_test_all by a series of assignments,
11572 not by a single assignment of a long string. The latter causes ksh
11573 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
11574 presumably because of a buffer overrun.
11576 2002-03-14 Paul Eggert <eggert@twinsun.com>
11578 * lib/autotest/general.m4 (at_times_skip):
11579 Renamed from at_times. Now a boolean.
11580 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
11581 says 'times: not found'.

11585 * bin/autoreconf.in (&study_gettextize): New.
11586 (&autoreconf): Handle newest gettextize.

11610 2002-03-11 Andreas Schwab <schwab@suse.de>

11613 does not do it if --with-lispdir is given.

11624 2002-03-08 Akim Demaille <akim@epita.fr>
11626 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
11628 2002-03-08 Akim Demaille <akim@epita.fr>
11630 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
11631 aliases the actual variables, and modifications of the former
11634 2002-03-08 Akim Demaille <akim@epita.fr>
11636 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
11637 because of C-c: have m4 output in tmp files, then mv them.

11660 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
11661 * lib/autoconf/general.m4 (AC_INIT): More informative error
11662 message for LIBOBJ.
11664 2002-03-04 Akim Demaille <akim@epita.fr>

11669 2002-03-04 Akim Demaille <akim@epita.fr>
11671 * doc/autoconf.texi (Transforming Names): Equality between target
11672 and host is irrelevant.
11673 (Specifying Names, Canonicalizing): Remove all references to the
11674 backward compatibility hooks. Rather, collect them all into...
11675 (Hosts and Cross-Compilation): this new section.
11676 * doc/install.texi (System Type): Ditto.
11677 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
11678 that `--host' implies cross-compilation.
11680 2002-03-04 Akim Demaille <akim@epita.fr>
11682 * doc/autoconf.texi (Evaluation Macros): New.
11683 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
11685 (_m4_foreach): Define the variant with immediate evaluation so
11686 that it contains exactly the items, not an expression which
11687 evaluation is the current item.
11688 (m4_re_string, m4_re_word): Don't over quote them.
11690 2002-03-04 Akim Demaille <akim@epita.fr>
11692 Instead of having stacking `shift's evaluated at the end, let
11693 `foreach' loops immediately evaluate them.
11695 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
11696 $*. This is the n-th time I change my mind, but hopefully this is
11699 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
11701 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
11702 it was only a hack for m4_text_wrap.
11703 (m4_car2): Remove, replaced by...
11705 (_m4_foreach): Adjust.
11706 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
11707 m4_bpatsubst for clarification.

11798 2002-02-05 Akim Demaille <akim@epita.fr>
11800 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

11823 optional are the sum of the previous files on the command line'.
11824 Also, pass `--reload-state=' on them, so...
11825 (handle_m4): don't.

11827 (M4sh): Rely on M4sugar.

11865 2002-01-28 Akim Demaille <akim@epita.fr>
11867 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
11868 AUTOTEST_PATH *after* it was set.
11869 Don't put `.' in the PATH: the user should be precise and `./' if
11870 needed. In addition, given that the test suite does some `cd', if
11871 `.' is in the path, the `tested programs' sections will report
11872 programs found in the test suite's directory, while during the
11873 tests (performed in their own directory), these programs are no
11874 longer visible. In other words, the results is confusing and

11951 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11952 and PACKAGE_BUGREPORT from here...
11953 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the

11978 * doc/autoconf.texi (New Macros): Tweak wording.
11980 2001-12-14 Akim Demaille <akim@epita.fr>
11982 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11983 trailing files, don't apply `-rf' to files which might not be
11984 created by configure (core, core.*, and *.core), but just `rm -f'.
11985 Suggested by Jonathan Kamens.
11987 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11989 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
11991 2001-12-14 Akim Demaille <akim@epita.fr>
11993 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
11995 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
11997 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
11998 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
11999 abs_srcdir, top_srcpath to abs_top_srcdir.
12000 (_AC_OUTPUT_FILES): Adjust.
12001 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
12002 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
12003 * tests/wrappl.in, tests/wrapsh.in: Adjust.
12005 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
12007 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
12008 C/Fortran linking on HP/UX, by extracting the Fortran library
12009 search path from the LPATH line in the $F77 -v output.
12011 2001-12-12 Kevin Ryde <user42@zip.com.au>
12013 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
12014 forbidden file descriptors table.
12016 2001-11-26 Akim Demaille <akim@epita.fr>
12018 * bin/autoscan.in (%c_keywords): Build it at top level.
12019 Map to 1 in order to simplify its uses.
12021 2001-11-26 Akim Demaille <akim@epita.fr>
12023 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
12024 Remove $filepath, useless.
12025 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
12026 variables, they are really part of the tokens.
12027 Split the input line on spaces and then look for tokens.
12028 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
12029 because of `lex$U.$(OBJEXT)'.
12030 (&scan_files): Use "@list" instead of join.
12031 * doc/Makefile.am (CLEANFILES): Add *.fns.
12033 2001-11-26 Akim Demaille <akim@epita.fr>
12035 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
12036 Remove, replaced by...
12037 * tests/wrappl.in: Be common for all the Perl executables.
12038 In particular autoscan and autoheader want -I.
12039 * configure.ac: Adjust.
12040 * lib/autoscan/headers: errno.h is portable.
12042 2001-11-26 Akim Demaille <akim@epita.fr>
12044 * bin/autoscan.in (used): New.
12047 2001-11-26 Akim Demaille <akim@epita.fr>
12049 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
12051 (&scan_sh_file): Remove a duplicate pattern.
12052 (&check_configure_ac): Use long options.
12053 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
12055 2001-11-26 Akim Demaille <akim@epita.fr>
12057 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
12058 Before, having a line containing the opening of a multi line
12059 comment made the whole line be ignored.
12061 2001-11-26 Akim Demaille <akim@epita.fr>
12063 * doc/autoconf.texi (Using an Autotest Test Suite): New.
12064 (testsuite Scripts): Be one of its subsection.
12065 (Autotest Logs): New.
12067 2001-11-26 Akim Demaille <akim@epita.fr>
12069 Test groups are now run two directories deeper.
12071 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
12072 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
12074 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
12075 top_srcdir, builddir and top_builddir.
12076 Use `at_*dir' relatively to the directory containing the
12077 suite, use `*dir' when relatively to the current group dir.
12079 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
12081 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
12082 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
12083 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
12086 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
12088 * doc/autoconf.texi (Using System Type): Add an example of `case
12089 $host' usage so people quit using `case $target' everywhere.
12091 2001-11-22 Akim Demaille <akim@epita.fr>
12093 * doc/autoconf.texi (Installation Directory Variables): Englishoes
12094 spotted by Jim Meyering.
12096 2001-11-16 Paul Eggert <eggert@twinsun.com>
12098 This patch implements a `long double' suggestion by Oliver Kiddle.
12100 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
12101 static, to catch errors if the value isn't known at compile-time
12102 and the compiler supports dynamic arrays. Change its name from
12103 `_array_' to `test_array' to avoid potential name clashes.
12104 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
12105 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
12106 better than double. Catch a bug in GCC 2.95.2 x86.
12107 * doc/autoconf.texi (C Compiler): Document the above.
12110 2001-11-13 Akim Demaille <akim@epita.fr>
12112 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
12114 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
12116 2001-11-13 Akim Demaille <akim@epita.fr>
12118 * lib/autotest/general.m4 (AT_INIT): After having run the test
12119 group, go back to the initial directory, not to at_suite_dir.
12121 2001-11-13 Akim Demaille <akim@epita.fr>
12123 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
12124 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
12125 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
12127 (AT_CHECK_CONFIGURE): Use absolute paths.
12128 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
12129 The problem is still the old one: there is no means in M4 (that I
12130 know about) to create a defining macro, because there is no means
12131 to create `$1' etc., therefore, the defining macro ``swallows''
12132 all the arguments meant to the defined macro.
12134 2001-11-13 Akim Demaille <akim@epita.fr>
12136 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
12137 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
12139 * tests/aclocal.m4: Remove, as it is no longer used.
12141 2001-11-13 Akim Demaille <akim@epita.fr>
12143 * lib/autotest/general.m4: Change `tests?' into `groups?' in
12144 variable names when referring to a single test group, or to
12145 `suite' when referring to the whole test suite.
12146 `at_last_test' is removed: m4 compute at_format itself.
12147 (at_stdout, at_stder1, at_stderr): New variables.
12148 (AT_CHECK): Use them.
12150 2001-11-13 Akim Demaille <akim@epita.fr>
12152 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
12154 Create `testsuite.dir/003/run' instead of `testsuite.003'.
12155 Do it as soon as a test fails, don't wait till the end of the test
12157 Don't remove $as_me.[0-9]*, since these files no longer exist.
12159 2001-11-13 Akim Demaille <akim@epita.fr>
12161 * tests/tools.at: Use absolute paths, since we are no longer run
12164 2001-11-13 Akim Demaille <akim@epita.fr>
12166 Now that tests are running in their own private dir, there is no
12167 need to list the files to remove at the end of tests groups.
12169 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
12170 (AT_data_files, at_data_files): Remove.
12171 (AT_CLEANUP, AT_DATA): Simplify.
12173 Remove the group dir if !debug && !failed.
12174 * tests/atspecific.m4: Adjust.
12176 2001-11-13 Akim Demaille <akim@epita.fr>
12178 Start a new layout for Autotest: `testsuite' creates
12179 `testsuite.dir' in which the at-check-line etc. files are to be
12180 found, and `testsuite.dir/003' where the test group 3 is run.
12182 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
12183 at_check_line_file, at_format, at_test_normalized, at_group_dir
12185 Create the directories.
12186 Use absolute paths for at- files.
12187 (AT_CHECK): Adjust.
12189 2001-11-11 Michael Matz <matz@kde.org>
12191 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
12193 (m4_car): Properly quote arguments.
12195 2001-11-13 Akim Demaille <akim@epita.fr>
12197 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
12198 with stricter rules on LIBOBJS.
12200 2001-11-12 Paul Eggert <eggert@twinsun.com>
12202 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
12203 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
12206 2001-11-12 Akim Demaille <akim@epita.fr>
12208 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
12210 2001-11-12 Akim Demaille <akim@epita.fr>
12212 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
12213 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
12214 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
12215 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
12216 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
12217 specify to what the macro should be defined (typically to 1).
12219 2001-11-12 Akim Demaille <akim@epita.fr>
12221 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
12224 2001-11-12 Akim Demaille <akim@epita.fr>
12226 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
12227 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
12228 definition used by Automake where LEX is +/- "${missing} lex" and
12229 `missing' itself contains variables.
12231 2001-11-12 Akim Demaille <akim@epita.fr>
12233 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
12234 Now that M4sh pushes BODY, the comments were output at the end of
12237 2001-11-08 Akim Demaille <akim@epita.fr>
12239 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
12240 that we can trace macros from aclocal.m4.
12241 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
12242 obsoleted, and redirect to the former anyway.
12243 Reported by Ralf Corsepius.
12245 2001-11-08 Akim Demaille <akim@epita.fr>
12247 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
12248 processed only if present.
12249 * tests/torture.at (Configuring subdirectories): Use autoreconf
12250 instead of successive calls to autoconf.
12251 Add a nonexistent subdirectory to exercise the patch above.
12252 Reported by Ralf Corsepius.
12254 2001-11-08 Kevin Ryde <user42@zip.com.au>
12256 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
12257 doesn't accept .S files.
12259 2001-11-07 Akim Demaille <akim@epita.fr>
12261 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
12262 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
12263 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
12264 * bin/autom4te.in (warn_forbidden): New.
12265 (handle_output): Use it.
12266 Read m4_pattern_forbid with messages.
12268 2001-11-05 Akim Demaille <akim@epita.fr>
12270 * bin/autom4te.in (--normalize): Remove.
12271 * lib/autom4te.in: Adjust.
12273 2001-11-05 Akim Demaille <akim@epita.fr>
12275 * tests/Makefile.am (testsuite): Rename this target as...
12276 ($(TESTSUITE)): this.
12279 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
12281 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
12282 the --prefix option, also remove it's argument.
12284 2001-11-05 Akim Demaille <akim@epita.fr>
12286 * doc/autoconf.texi (testsuite Invocation): Update.
12287 (Writing testsuite.at): Update.
12289 2001-11-03 Akim Demaille <akim@epita.fr>
12291 * doc/autoconf.texi: s/@code/@command/ where appropriate.
12293 2001-11-03 Akim Demaille <akim@epita.fr>
12295 * lib/Autom4te/General.pm: (&catfile, &canonfile)
12296 (&file_name_is_absolute): New, wrappers around routines from
12298 Use and export them.
12299 (&find_configure_ac): Optionally take a directory where to look at.
12300 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
12302 Default @ARGV to `.', not find_configure_ac.
12303 (&autoreconf): Argument is a directory.
12304 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
12305 * doc/autoconf.texi (autoreconf Invocation): Update.
12307 2001-11-03 Akim Demaille <akim@epita.fr>
12309 * lib/Autom4te/General.pm (@export_vars, @export_subs)
12310 (@export_forward_subs): New.
12311 Add basename, dirname, and fileparse.
12313 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
12314 Don't look for aclocal flags if we already know aclocal is not
12316 Move aclocal.m4t only if it exists.
12317 Reported by Ezra Peisach.
12319 2001-11-03 Akim Demaille <akim@epita.fr>
12321 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
12322 passed on command line, defaulting to ./configure.ac if present.
12323 (&maybe_autoreconf, File::Find): Remove, unused.
12324 (&autoreconf): If autoconf is not used, don't try to trace.
12326 2001-11-02 Akim Demaille <akim@epita.fr>
12328 * configure.ac: Bump to 2.52g.
12330 2001-11-02 Akim Demaille <akim@epita.fr>
12334 2001-11-02 Akim Demaille <akim@epita.fr>
12336 * config/config.guess, config/config.sub, doc/standards.texi:
12337 * config/lispdir.m4: Update from masters.
12338 * configure.ac: Bump to 2.52f.
12340 2001-11-02 Akim Demaille <akim@epita.fr>
12342 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
12343 Don't run aclocal when aclocal.m4 is not from aclocal.
12345 Don't run libtoolize and gettextize if --install is not given.
12347 2001-11-01 Paul Eggert <eggert@twinsun.com>
12349 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
12350 be invoked before _AS_LINENO_PREPARE.
12351 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
12352 than character ranges.
12354 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
12355 invoking AS_BASENAME. Set the locale variables to 'C' if
12356 possible, as POSIX requires this to get the traditional
12358 * doc/autoconf.texi (Special Shell Variables): Describe the above.
12360 2001-10-31 Paul Eggert <eggert@twinsun.com>
12362 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
12363 with {}, as that triggers a bug in Bash 2.05.
12365 (_AS_LINENO_PREPARE): Use Sed rather than
12366 Awk. Fix the sed prepass to work even if there are multiple
12367 instances of $LINENO on the same line. Do not substitute for
12368 other variables like $LINENOT. Do not check file dates; such a
12369 check is unreliable on sufficiently fast machines, and removing
12370 the check makes the code simpler and more reliable. Check for
12371 output and chmod failures.
12373 * doc/autoconf.texi (Special Shell Variables): Document
12376 2001-10-31 Akim Demaille <akim@epita.fr>
12378 * tests/Makefile.am (atconfig): Remove this target, Automake
12381 2001-10-31 Akim Demaille <akim@epita.fr>
12383 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
12384 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
12385 provided, while it is optional.
12386 * configure.ac: Adjust.
12388 2001-10-26 Paul Eggert <eggert@twinsun.com>
12390 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
12391 lib/Autom4te/Struct.pm:
12392 Require Perl 5.005_03 instead of just 5.005, as some tests fail
12395 * doc/autoconf.texi (Special Shell Variables): Document some
12396 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
12398 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
12399 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
12400 eval $LINENO is not portable in practice.
12402 2001-10-24 Akim Demaille <akim@epita.fr>
12404 * lib/Autom4te/General.pm (backname): New.
12406 2001-10-24 Akim Demaille <akim@epita.fr>
12408 * m4/: Remove, merged into...
12411 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
12413 * doc/autoconf.texi (Shellology): Mention the problems with bash
12414 2.05's use of ANSI quoting in its `set' builtin.
12416 2001-10-22 Paul Eggert <eggert@twinsun.com>
12418 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
12419 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
12420 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
12421 POSIX decided to standardize on the int flavor of strerror_r.
12422 Always do char* test, as there's no reason not to.
12423 Assign to a char* var, to catch strerror_r that returns int*.
12425 * doc/autoconf.texi (Particular Functions):
12426 Document the above changes. Also, document the fact that
12427 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
12429 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
12431 2001-10-20 Akim Demaille <akim@epita.fr>
12433 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
12434 the executable was missing from the log.
12436 2001-10-20 Akim Demaille <akim@epita.fr>
12438 * lib/Autom4te/General.pm (&update_file): If destination is
12439 unchanged, remove the source.
12440 (&up_to_date_p): Don't be verbose, be debug.
12441 * bin/autoreconf.in: No longer support --m4dir.
12442 (&autoreconf): Display the full path of the configure.ac we are
12444 Trace it only once.
12445 Be sure to honor --force with gettextize.
12446 Always run aclocal.
12447 * doc/autoconf.texi: Adjust.
12449 2001-10-20 Akim Demaille <akim@epita.fr>
12451 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
12453 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
12454 `intl' is already present, as it refuses unless --force.
12455 (&parse_args): Use -I, --include instead of the old Autoconf
12457 ($localdir, $autoconf_dir): Remove.
12459 (&maybe_autoreconf): New, to preserve $_ for File::Find.
12461 2001-10-19 Jens Petersen <petersen@redhat.com>
12463 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
12464 * doc/autoconf.texi (Particular Programs): Likewise.
12466 2001-10-19 Akim Demaille <akim@epita.fr>

12931 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
12932 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
12934 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12936 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
12937 * bin/autoupdate.in: Ditto.
12938 * bin/autoheader.in: Reworded a few comments.
12939 * bin/autoconf.in: Reworded help text for a few options.
12940 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,

12943 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
12945 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
12946 already have $file). Set output files to binary mode (helps avoid
12947 CR issues on DOSish systems).
12949 2001-09-19 Akim Demaille <akim@epita.fr>
12951 * lib/autotest/general.m4: Englishoes.
12952 From Tim Van Holder and Alexey Mahotkin.
12954 2001-09-18 Paul Eggert <eggert@twinsun.com>
12956 * doc/autoconf.texi (Common Shell Constructs): New node,
12957 documenting AS_DIRNAME.
12958 (Limitations of Usual Tools): Refer to it when discussing dirname.
12959 Also, update discussion of POSIX standard to reflect latest draft.
12961 * lib/autoconf/c.m4:
12962 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
12964 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
12965 Do not pass a first argument with leading '-'
12966 to expr, by parenthesizing initial integers that might be negative.
12968 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
12969 now merely checks whether it is an error to pass an argument
12972 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
12973 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
12974 whether it is a (compile-time) error to pass an argument to
12975 getpgrp. This simpler test supports the revised documentation,
12976 and is all that AC_FUNC_GETPGRP's users really need.
12978 2001-09-18 Akim Demaille <akim@epita.fr>
12980 * doc/autoconf.texi (Limitations of Make) <$<>: New.

12988 2001-09-18 Paul Wagland <paul@wagland.net>
12990 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12992 Add test for AS_BASENAME.
12993 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12994 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12995 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12996 * tests/base.at: Fixed the expected responses. The old ones were
12998 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12999 the documentation claims it should (and how it behaved in 2.13).
13001 2001-09-18 Akim Demaille <akim@epita.fr>
13003 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
13004 the AC_CONFIG_COMMANDS invocation.
13005 This also solves the name clash problems.
13006 Don't set the package's ID.
13007 * lib/m4sugar/Makefile.am (version.m4): Revamp.
13008 No longer to be shipped.
13009 (version.in): Remove.

13012 Use `m4_PACKAGE_STRING'.
13013 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
13014 the only optional argument is the name of the test suite.
13015 Expect `package.m4' to define the package signature.
13016 * lib/autom4te.in (Autotest): Add `package.m4?'.
13017 * tests/Makefile.am (package.m4): New.
13018 * tests/suite.at: ifnames is a victim.

13023 AC_LIBSOURCE, AC_CONFIG_FILES.
13024 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
13025 program version string doesn't match the package's.
13026 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

13031 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13032 Allow expression to return any value that can fit into unsigned long
13033 (not int, as before). Check for output errors.

13037 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
13038 Always include <stdio.h> and <stdlib.h>. Evaluate
13039 the expression in an extra function before these includes. Call
13040 fprintf "%d" only after ensuring the argument is of type 'int'.
13041 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
13043 2001-09-17 Paul Eggert <eggert@twinsun.com>
13045 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
13046 or CFLAGS=-O5. In that case, the linker has a relaxed view of
13047 fatal errors, and AC_CHECK_LIB causes it to include libraries even
13048 when they don't exist.
13050 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
13051 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
13054 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
13055 version with the version used by fileutils 4.1, except use
13056 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
13059 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
13061 2001-09-13 Akim Demaille <akim@epita.fr>

13101 * lib/autotest/general.m4 (AT_INIT): Create and remove
13102 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
13103 test suites can cohabit.

13107 * tests/mktests.sh: Don't output banners for empty test files.

13213 2001-09-05 Akim Demaille <akim@epita.fr>
13215 Be ready to handle filenames as stupid as `dnl.at', for if even
13216 the maintainer is dumb enough to do that...
13218 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
13219 excellence in M4 quotation: consider `__file__' is active.
13221 And BTW, when invoking m4, pass the --include in the right order:

13307 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

13396 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

13898 2001-08-15 Akim Demaille <akim@epita.fr>

13982 magic values from an object file when cross-compiling.
13983 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13985 2001-08-10 Akim Demaille <akim@epita.fr>
13987 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13989 Suggested by Russ Allbery.
13991 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13993 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13994 current $prefix to the sub-configures.
13996 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13998 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable

14001 2001-08-09 Akim Demaille <akim@epita.fr>
14003 * bin/autom4te.in ($icache): Load it only if older than autom4te.
14005 2001-08-07 Akim Demaille <akim@epita.fr>
14007 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
14009 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
14010 No need to remove the files before and after the each test, before
14011 each test and at the end of the suite is enough.
14012 Display only the children `times', not the shell's.
14013 If the test failed or was skipped, at-times is not available.
14015 2001-08-07 Akim Demaille <akim@epita.fr>
14017 Always produce testsuite.log, including when there are no
14018 failures. This helps getting information on skipped tests, and
14019 duration of the tests. Err, implement the latter btw.
14021 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
14022 Dump information on the first run of each test.
14023 (AT_CLEANUP): Create `at-times' containing the duration of the
14026 2001-08-07 Akim Demaille <akim@epita.fr>
14028 The use of `dumpstat' revealed that `len' was used although it
14029 should not. m4_text_wrap was using it, but in the Autoconf world
14030 where it is legal. Hence (i) test M4sh in its own world, not
14031 Autoconf's, and (ii), ahem, fix the bug :)
14033 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
14034 does not like `' instead of [].
14035 (AT_INIT): Forbid `^_?AT_'.
14036 And don't output such tokens.
14037 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
14038 `script.as', and `autom4te.cache'.
14039 Remove `empty' and `macro' which are no longer used.
14040 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
14041 * tests/m4sugar.at: Use it.
14042 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
14044 2001-08-07 Akim Demaille <akim@epita.fr>
14046 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
14048 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
14050 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
14052 2001-08-04 Akim Demaille <akim@epita.fr>
14054 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
14055 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
14057 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
14058 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
14059 (AC_F77_MAIN): Likewise.
14061 2001-08-04 Akim Demaille <akim@epita.fr>
14063 Don't rely on M4sugar outputting the patterns in files, since we
14064 might process the output _without_ running m4, hence without these
14067 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
14068 * bin/autom4te.in (@Request::includes): Remove, unused.
14069 (@Request::source): Rename as...
14070 (@Request::input): this.
14071 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
14072 (&handle_output): Fetch the patterns from the traces.
14073 `$forbidden' and `$allowed' are constant: use m//o.
14074 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
14075 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
14077 2001-08-04 Akim Demaille <akim@epita.fr>
14079 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
14080 autoconf', i.e., in addition to caching traces, cache the output.
14082 * bin/autom4te.in (Request::cache): Rename as...
14083 (Request::id): this.
14084 ($cache, $icache, $tcache, $ocache): New.
14085 (&handle_m4): Save M4 output in the cache instead of $tmp.
14086 (&handle_output): Adjust.
14087 (&up_to_date_p): Check that the output cache is up to date too.
14088 (top level): Run `&handle_m4' iff force or the cache is invalid.
14089 Run `&handle_output' if the output cache is more recent.
14091 2001-08-04 Akim Demaille <akim@epita.fr>
14093 * bin/autom4te.in ($force): New.
14094 (&parse_args, &print_usage): -f, --force is a new option.
14095 (&handle_output): CPP directives might have spaces after `#'.
14096 (&parse_args): The first file only can be frozen.
14098 2001-08-04 Akim Demaille <akim@epita.fr>
14100 Don't let autom4te compute the `include' traces several times:
14101 first check that the trace cache file is up to date, and then
14102 compare its timestamp with that of the output.
14104 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
14105 the preamble. Don't require 5.005 as Autom4te::General does it,
14106 and better yet (use `use', not `require'!).
14107 * lib/Autom4te/Struct.pm: Rename the last occurrences of
14108 Class::Struct as Autom4te::Struct.
14109 * lib/Autom4te/General.pm (File::stat): Use it.
14110 (&mtime): New, export it.
14111 * bin/autom4te.in: Use it.
14112 Declare `$req' is invalid if it is outdated.
14113 Don't declare it valid before saving it if something went wrong.
14115 2001-08-04 Akim Demaille <akim@epita.fr>
14117 Autom4te shall not encode Autoconf data, and preselecting traces
14118 must be proposed to the users.
14120 * bin/autom4te.in (@required_trace): Remove.
14122 (&parse_args, &print_usage): -p, --preselect is a new option.
14123 (&up_to_date_p): Adjust.

14128 * tests/tools.at (autoconf --trace: user macros): Check traces on
14129 macros invoked without arguments, and macros invoked with multiple
14132 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

14137 2001-08-03 Akim Demaille <akim@epita.fr>
14139 * bin/autoconf.in ($@): Work around the usual sh bug.
14142 2001-08-03 Akim Demaille <akim@epita.fr>
14144 Clean up the handling of the M4 builtins tracing exception.
14146 * bin/autom4te.in (Request::request): Don't complete M4 builtins
14148 (@m4_builtins): Rename as...
14149 (@m4_builtin): this.
14150 (%m4_builtin_alternate_name): New.
14151 (&parse_args): Complete the trace requests with alternate names.

14153 (&trace_requests): Remove, unused.

14157 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
14158 m4_if, and m4_wrap.
14160 2001-08-03 Akim Demaille <akim@epita.fr>
14162 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
14163 (m4_divert_pop): Dump the whole diversion stack when a diversion
14165 * bin/autom4te.in (&handle_output): Remember of the first
14166 occurrence of a possibly undefined macro, not the last.
14167 Complain about the possibly undefined macros in the same order as
14168 the appear in the output.
14169 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
14170 * tests/tools.at (autoconf: forbidden tokens, basic)
14171 (autoconf: forbidden tokens, exceptions): No longer sort
14172 autoconf's stderr, as it is now deterministic.
14173 Check that `dnl' is caught.
14175 2001-08-01 Akim Demaille <akim@epita.fr>
14177 * configure.ac: Bump to 2.52c.

14194 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
14195 `END', as `Autom4te::General::END' will be triggered.
14196 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
14197 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
14198 system to run `mv', `rm', and `cmp'.

14202 * lib/Autom4te/General.pm (&unique): New.
