9 (Limitations of Usual Tools): Also list \< and \>, and mention that
10 HP-UX's grep, like the one from Solaris, does not support that syntax.
12 2007-03-09 Stepan Kasal <kasal@ucw.cz>
14 * doc/autoconf.texi (Specifying Names): `--host' does not
15 change the build type.
17 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

31 universal binaries. Problem reported by Elias Pipping.
33 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
35 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
36 * doc/autoconf.texi (C Compiler): Document this. There is a new
37 extra argument ACTION-IF-UNIVERSAL.
38 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
39 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.

52 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
53 status of rm so we know when it failed.
54 If cleaning of test dir failed before running the test, warn.
55 Output the line separator in verbose mode before the warning
56 to make clear the warning belongs to the following test.
58 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
60 * doc/autoconf.texi (Parentheses): Mention problem with (( in
61 shells.
63 2007-02-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
64 and Paul Eggert <eggert@cs.ucla.edu>

83 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
84 input from /dev/null in awk test, so even Solaris /usr/bin/awk
85 will not wait for input with a script containing only a BEGIN
86 rule.
88 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>

106 2007-01-31 Eric Blake <ebb9@byu.net>
108 * THANKS (people): Update.
110 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
112 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
113 latest version.
114 (Shell Substitutions): Note problems with @{var:=value} etc.
115 Add a new section for problems with @{#var} etc. Problem noted
116 by Ralf Wildenhues. See:

119 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
121 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
122 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
123 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
124 substitution will still be done by the special code.
125 Report by Jim Meyering.
127 * doc/autoconf.texi (File System Conventions): Mention that
128 $PATH_SEPARATOR is for the build system only.
129 Report by Keith Marshall.
131 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
133 * doc/autoconf.texi (Setting Output Variables): Mention that
134 all non-NUL characters are ok in substituted values.
135 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
136 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
137 carriage return for $AWK, needed for BSD awk.
138 * tests/torture.at (Substitute and define special characters):
139 Test all 8 bit non-NUL characters.
140 Report against Automake by Patrick Welche.
142 2007-01-15 Stepan Kasal <kasal@ucw.cz>
144 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
146 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
148 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
149 early on the reader side, drop stderr of the input to avoid
150 `broken pipe' error output; this may happen even with shell
151 builtin `echo' of some bash versions. Reports by Ian Macdonald
152 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
154 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
156 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
157 separate items of `ac_user_opts', to avoid long lines.
158 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
160 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
162 * doc/autoconf.texi: Fix some typos.
164 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
166 Fix some wording problems noted by Paolo Bonzini in:
167 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
168 * doc/autoconf.texi (Signed Overflow Examples): Give more
169 discussion about the allow_superuser_privileges example,
170 and change it a bit to make things clearer.
171 (Optimization and Wraparound): Clarify whether the compiler
172 will generate an infinite loop for the example derived from
173 Autoconf's mktime test.
174 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
175 Also, clarify unsigned multiplication overflow.
177 2007-01-04 Eric Blake <ebb9@byu.net>
179 * bin/Makefile.am (RELEASE_YEAR): New macro.
180 (edit): Use it to supply correct copyright year to scripts.
181 * bin/autoconf.as (version): Use it.
182 * bin/autoheader.in ($version): Likewise.
183 * bin/autom4te.in ($version): Likewise.
184 * bin/autoreconf.in ($version): Likewise.
185 * bin/autoscan.in ($version): Likewise.
186 * bin/autoupdate.in ($version): Likewise.
187 * bin/ifnames.in ($version): Likewise.
189 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
191 * doc/autoconf.texi (Integer Overflow): Revised based on today's
192 feedback. The most important changes document what happens when
193 you convert an out-of-range value to a signed integer type, and
194 say that (sum < a) != (b < 0) reliably detects overflow when sum =
195 a + b.
197 * doc/autoconf.texi (Integer Overflow): Greatly expand and
198 rewrite, taking notions from the recent discussion on the gcc and
199 autoconf mailing lists; please see
200 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
201 and follow the many links.
202 (Integer Overflow Basics, Signed Overflow Examples):
203 (Optimization and Wraparound, Signed Overflow Advice):
204 (Signed Integer Division): New sections.
206 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
208 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
209 preprocessor macro arguments in traced name.
210 * doc/autoconf.texi (Defining symbols): Document longstanding
211 support for AC_DEFINE-ing macros with arguments, and document
212 behavior when the same variable has multiple AC_DEFINEs.
213 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
214 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
215 macros directly, giving much shorter and simpler code.
217 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
219 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
220 space before "$ac_configure_args" to prevent a 'config.status
221 --recheck' failure if ac_configure_args doesn't contain a leading
222 space. This works around a problem with the XEmacs configure.ac,
223 which uses the (undocumented) ac_configure_args variable
224 inconsistently with Autoconf.
226 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
228 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
229 Include <limits.h>, and use its INT_MAX to rewrite the
230 j loop so that it does not overflow 'int'. Problem reported by
231 Ralf Wildenhues in
232 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
233 Play it safe by shifting left by 1 rather than multiplying by 2,
234 as GCC is less likely to optimize this away when the value
235 is signed (when it assumes overflow leads to undefined behavior).
236 Also, don't assume time_t uses two's complement.
238 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
240 * tests/torture.at (Substitute a 2000-byte string): Avoid using
241 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
242 dumps core on it. Report by Tim Rice.
244 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
246 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
247 --disable-option-checking to --help output even when
248 AC_PRESERVE_HELP_ORDER is not used.
249 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
250 --with argument, rather than argument with [-.] replaced by
251 underscores.
252 * NEWS: Fix typo in previous change; the news was in the
253 wrong section.
255 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
257 * NEWS: Warnings are now generated by default for unknown
258 --enable-* and --with-* options.
259 * doc/autoconf.texi (Option Checking): Renamed from
260 (Configure Option Checking). Tighten up the wording a bit.
261 (External Software, Package Options): Cross-reference to Option
262 Checking, and use this to shorten our section.
263 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
264 "$x" to test "x$foo" != x.
265 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
266 Don't warn if $enable_option_checking is "no".
267 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
268 ac_unrecognized_opts to the empty string.
269 Don't echo the unrecognized opts, as this might mishandle
270 backslashes or leading -.
271 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
272 usage next to the other --disable-FEATURE options in the
273 help string.
275 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
277 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
278 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
279 Print warning for unrecognized --with and --enable options
280 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
281 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
282 Disable option checking when subdirs are configured.
283 (AC_OUTPUT): If warnings are enabled, print warning about
284 unrecognized --with and --enable options at the end of
285 the configure output (as well as at the beginning).
286 * doc/autoconf.texi (Option Checking): New node.
287 Document new option warning functionality.
289 2006-12-16 Eric Blake <ebb9@byu.net>
291 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
292 * NEWS: Start news for current version.
294 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
296 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
297 Define HAVE_GETMNTENT to 1, not to the empty string.
298 Problem originally reported by Jochen Friedrich in
299 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
301 This change prompted by a problem report by Andrey Simonenko in
302 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
303 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
304 object-like macros only, in the traditional portable character
305 set.
306 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
307 Warn about attempts to define things that are not identifiers.
308 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
309 awful hack that AC_DEFINEd macro names containing parentheses.
311 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
313 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
314 too drastic, even if Texinfo in theory requires it for info mode.
316 (config.status Invocation): Renamed back from Recreating a
317 Configuration).
318 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
319 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
321 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
323 * NEWS: Version 2.61a.
325 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
326 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
328 * NEWS: Document changes with echo and printf, and the lack
329 of limits on the total size of multi-line values of substituted
330 variables, and the AC_FUNC_FSEEKO fix.
332 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
334 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
335 Writing configure.ac.
336 (Autoconf Input Layout): Renamed from configure.ac Layout.
337 (Recreating a Configuration): Renamed from config.status Invocation.
338 (Obsolete Recreation): Renamed from Obsolete config.status Use.
339 (acconfig Header): Renamed from acconfig.h.
340 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
341 (Writing Testsuites): Renamed from Writing testsuite.at.
342 (Autom4te Cache): Renamed from autom4te.cache.
344 * BUGS: Remove mention of VPATH problem, since it's now documented
345 not to be a bug in the Autoconf build procedure itself, but rather
346 a problem with the proprietary `make' programs.
348 * doc/autoconf.texi (Build Directories): Add a cross reference
349 to VPATH and Make.
351 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
352 * doc/standards.texi: Sync from gnulib.
354 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
355 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
356 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
357 generated automatically.
359 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
361 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
362 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
363 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
365 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
367 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
368 `CEOF$ac_eof' special marker, the awk script cannot contain a
369 line matching `^CEOF', so this is not needed any more.
370 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
371 special marker in the test.
373 2006-12-06 Stepan Kasal <kasal@ucw.cz>
375 * tests/tools.at (autom4te preselections): Use `find -newer';
376 remove one of the sleeps.
378 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
379 more readable, using ...
380 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
382 * doc/autoconf.texi (autoheader Invocation): Do not double-
383 quote the parameter of `AH_BOTTOM' in the example.
385 2006-12-05 Stepan Kasal <kasal@ucw.cz>
387 * doc/autoconf.texi (Configuration Headers): Remove the
388 example with multiple input files.
389 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
390 multiple input files.
392 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
394 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
395 creating the awk substitution script, handle one input line at a
396 time, so that the maximum length of a substituted (multi-line)
397 value is not limited by the size of the sed pattern space.
398 The trade-off is a slightly repetitive sed script.
399 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
400 can only have up to 7 characters, due to Solaris 10 /bin/sed.
401 * tests/torture.at (Substitute a 2000-byte string): Increase the
402 test with several long lines, they should not be caught by sed
403 limits any more.
405 * tests/tools.at (autom4te preselections): New test, to flag
406 entries missing from autom4te.cfg.
407 Report by David Byron <dbyron@hheld.com>.
409 * tests/torture.at (Substitute a 2000-byte string): Actually use
410 AC_PROG_AWK, so the last change works as intended.
411 (Substitute and define special characters): Likewise.
412 (Substitute a newline): Likewise.
414 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
415 instead of `awk' consistently.
416 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
417 * tests/torture.at (Torturing config.status): Test both the
418 result of AC_PROG_AWK and plain awk.
419 (Substitute a 2000-byte string): Likewise.
420 (Substitute and define special characters): Likewise.
421 (Substitute a newline): Likewise.
423 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
425 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
426 can be assigned to a function pointer. Problem reported by
427 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
428 part of a patch by Ralf Wildenhues in that same bug report.
430 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
432 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
433 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
435 2006-12-01 Eric Blake <ebb9@byu.net>
437 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
438 cross-compiling from cygwin to mingw.
439 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
440 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
441 to lib/autoconf/c.m4.
443 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
445 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
446 string for more reliable failure. Wrap the entire test that
447 causes the broken Solaris printf to dump core, in a subshell,
448 so the segmentation fault message is reliably suppressed.
449 Fix shell expansion errors by using /usr/ucb/echo always;
450 avoid an error on systems without it by another subshell.
451 Avoid m4 expansion of `$1'. Set the zeroth argument of the
452 subshell-$as_echo to `as_echo', for better error message.
454 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
456 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
457 `BASH_SOURCE' contain a newline, set them to empty, as they may
458 not be unset.
460 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
462 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
463 years and is too hard to maintain now. The last straw was
464 reported by Jerker Baeck in
465 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
466 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
467 * doc/autoconf.texi (Particular Functions): Move
468 AC_FUNC_SETVBUF_REVERSED from here...
469 (Obsolete Macros): ... to here. Say that it does nothing now.
470 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
471 Turn into (almost) a no-op.
473 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
474 (AC_C_VOLATILE):
475 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
476 These macros are obsolescent and new applications shouldn't need them.
477 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):

488 Ralf Wildenhues.

507 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
509 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
510 in the sed script that mangles the awk script: delete up to the
511 first exclamation mark only.
512 * tests/torture.at (Substitute and define special characters):
513 Test '!' too.
515 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
517 Rewrite config files generation: avoid quadratic growth in
518 the number of substituted variables by using awk instead of sed
519 for the bulk of the substitutions.
520 * NEWS: Mention this.
521 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
522 forbidden in the output (and thus input) file.
523 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
524 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
525 generate just one large awk script for substitutions,
526 eliminating much of the earlier complexity, while adding some
527 new complexity. Only expand the substitution templates at
528 configure time, for smaller configure script size. If
529 _AC_SUBST_FILES are used, test 'awk' for working getline support
530 at config.status time. If absent, interpolate through the
531 shell. The awk script was written with much help
532 from Paolo Bonzini and Paul Eggert.
533 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.

539 substitute a line with 1000 words, and a variable with several
540 long lines.
541 (Substitute and define special characters): Test awk special
542 characters, and put substitution input strings `@foo@' in the
543 output, to test that no recursion happens; test several other
544 combinations from Paolo Bonzini.
546 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
548 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
549 that replaced echo with AS_ECHO where this wasn't necessary.
550 Problem reportd by Ralf Wildenhues.
551 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
552 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
553 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
555 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
557 * lib/freeze.mk (GREP): Removed, no need to initialize this.
559 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
561 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
562 that traditional Awk lacks 3-arg "split". It has it.
563 Mention that FS must be a single character, and a few other
564 99-byte limits of traditional Awk.
565 Mention that if (i in a) doesn't work with traditional Awk.

571 (Newline-CODE-BS-newline in command):
572 (Single-quote-BS-newline in command):
573 (Single-quote-newline-BS-newline in command):
574 Use printf '%s\n' instead of echo, for portability to hosts
575 where echo interprets backslashes. This will break on hosts
576 that lack printf, but for now let's assume all such hosts
577 are dead (if not, we should get reports of test failures).
579 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
581 'echo' has some portability problems, when given a first argument
582 with a leading '-', or when given any argument containing '\'.
583 Avoid using 'echo' in these cases.

615 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"

618 use AS_ECHO.
619 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
620 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use

735 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
736 ./micro-suite.
738 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
740 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
741 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
742 Imported from a similar patch to gnulib by Bruno Haible.
744 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

762 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
763 and Stepan Kasal <kasal@ucw.cz>
765 Handle special characters in test case titles correctly.
766 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
767 properly.
768 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
769 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
770 argument. Extend to check titles printed by ./micro-suite and
771 ./micro-suite -l and the title in micro-suite.log.
772 (Backquote in a test title,
773 Single-quote in a test title,
774 Double-quote in a test title): Don't expect failure anymore.
775 (Backslash in a test title): Put a non-whitespace character after the
776 backslash so that Bourne shells might actually see it as an escape
777 sequence.
778 (Brackets in a test title,
779 Pound in a test title,
780 Comma in a test title,
781 Quoted Macro in a test title,

786 Macro with backslash in a test title): New tests expected to fail.
787 * tests/torture.at (#define header templates): M4-quote this title in
788 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
789 The visible effect was a stray [] in the testsuite output.
791 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
793 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
794 `trap ... 0' inside a function, for AIX sh.
796 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
798 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
799 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
800 5363) simply issues a warning when dividing by zero at compile
801 time. Problem reported by Elias Pipping.
803 2006-10-26 Eric Blake <ebb9@byu.net>
805 * THANKS: Update.
806 * doc/autoconf.texi (Evaluation Macros): Improve the example to
807 show effect on macros that expand with commas.
808 Reported by Joel E. Denny.

834 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
835 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
836 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
837 reported by Nelson H. F. Beebe for Coreutils 6.4.
839 * tests/tools.at (autoconf --trace: user macros): Remove test
840 for tracing multiline macros, since m4 1.4.7a uses a different
841 way to number lines. Problem reported by Ralf Wildenhues.
843 2006-10-24 Stepan Kasal <kasal@ucw.cz>
845 * bin/autom4te.in (handle_m4): Do not redirect stdin to
846 /dev/null since the heuristics for interactive behaviour was
847 fixed in CVS m4.
849 * bin/autom4te.in: With --force, always refresh the output
850 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

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

903 looking for special shell characters.
904 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
905 macro defined by AS_VAR_PUSHDEF before passing it as a

917 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
919 (Imported from Automake.)
920 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
921 which incorrectly sets the mode of an existing destination
922 directory. In some cases the unpatched install-sh could do the
923 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
924 system. We hope this is rare in practice, but it's clearly worth
925 fixing. Problem reported by Alex Unleashed in
926 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
927 Also, don't bother to check for -m bugs unless we're using -m;
928 suggested by Stepan Kasal.

989 by Ralf Wildenhues.
991 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
993 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
994 AC_PROG_CC.
995 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
997 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
999 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1000 the NonStop platform.
1001 * doc/autoconf.texi (Posix Variants): Likewise.
1002 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1004 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1005 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1006 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1007 Use a better substitute, by inspecting the output of "ls"
1008 rather than just using ":".
1009 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1010 rather than AS_EXECUTABLE_P, since we needn't worry about
1011 non-regular files here.
1013 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1014 due to configuration hassles with this. See Tonya Underwood's report
1015 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1016 * doc/autoconf.texi (Special Shell Variables): Likewise.
1018 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1019 Stepan Kasal <kasal@ucw.cz>
1021 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
1022 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1024 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1026 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1027 initialization which is not inherited through the environment
1028 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1029 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1031 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1033 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1034 problems with mkdir -p -m.
1036 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1038 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1039 comment about ac_cpp_err; it was incorrect, and anyway
1040 ac_cpp_err is being removed below.
1041 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1042 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1043 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1044 nobody uses it.
1045 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1046 with werror_flag and conftest.err and so forth. This is more
1047 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1048 and anyway the user shouldn't normally want to see this gorp logged.
1049 Problem reported by Ralf Wildenhues.
1050 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1051 empty, not 'no', since the rest of the code uses 'test -z'.
1053 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1055 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1056 Use a single call to AC_DO_TOKENS rather than multiple, for
1057 efficiency.
1058 (_AC_LINK_IFELSE): Test that resulting file is executable.
1059 Problem reported by mwoehlke in
1060 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1062 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1063 than creating a file to use with test -x; this is much faster.
1065 2006-10-02 Bruno Haible <bruno@clisp.org>
1067 * lib/autom4te.in (Automake-preselections): Add
1068 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1070 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1072 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1073 standard error, `experr' should be used, not `expout'.
1075 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1077 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1078 fseeko testing program twice; just use the earlier result.
1079 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1080 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1081 still doesn't let the program compile.
1082 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1083 failed.
1085 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1086 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1087 include it, without including anything else.
1088 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1089 expressions.
1090 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1092 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1094 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1095 `error.h', and include it, for a `error_at_line' prototype.
1096 Use a nonempty format string in the link test.
1097 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1098 for a declaration of wait3.
1100 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1102 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1103 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1104 can apply to constants too, and that it checks for macro defns.
1105 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1106 and simply cast the identifier to void. This handles structure
1107 values. Problem reported by Ralf Wildenhues.
1108 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1110 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1112 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
1113 structure, and function symbols.
1115 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1117 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
1118 member.
1120 2006-09-25 Paul Eggert <eggert@cs.ucla.edu>
1122 * NEWS: Recommend M4 1.4.7 instead of 1.4.6.

1126 2006-09-25 Paul Eggert <eggert@cs.ucla.edu>
1127 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1129 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
1130 warnings (uninitialized value).
1131 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
1132 present.
1133 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Likewise, add

1142 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.
1143 Report by Olly Betts.
1145 2006-09-19 Eric Blake <ebb9@byu.net>

1163 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
1164 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
1165 --error-output, to avoid warnings with M4 2.0.
1167 2006-09-19 Stepan Kasal <kasal@ucw.cz>
1169 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
1170 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
1171 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
1173 2006-09-15 Stepan Kasal <kasal@ucw.cz>
1175 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Eliminate the
1176 expansion of AC_CHECK_FUNCS.
1178 2006-09-14 Stepan Kasal <kasal@ucw.cz>
1180 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
1181 mistaken comment: the path has to be relative; do not use
1182 the path at runtime.
1184 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1186 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the
1187 argument to `--prefix' for sub-configure scripts.
1188 Pass `--silent' to sub-configure scripts.
1189 * tests/torture.at (Configuring subdirectories): Add tests
1190 for both changes.
1191 * doc/autoconf.texi (Setting Output Variables): Fix example to
1192 not show `--silent' being passed to a `configure' re-run.
1194 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
1196 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1197 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1198 for the existence of the directory at configure-time. That's
1199 too late, anyway. Problem reported by Stefan Seefeld.
1201 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1202 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1203 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1205 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1207 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1208 works with GNU M4 1.4.3 again; make the normalized form
1209 match the current m4 message; fix the description.
1210 * test/tools.at (autom4te cache): Adapt to the change.
1212 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1214 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1215 to catch glibc bug 2821
1216 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1218 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1219 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1220 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1221 assume C89.

1241 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1243 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1244 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1245 accept files with extension `.f'. For consistency, also prefer
1246 xlf over f77.
1247 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1248 from last patch.
1250 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

1269 except the first two arguments are reversed.
1270 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1271 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1272 caches nor outputs a diagnostic. Suggested by Bruno Haible.

1274 equivalent to the old AC_COMPUTE_INT.
1275 (AC_COMPUTE_INT): No longer caches or reports. New signature.

1280 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
1282 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1283 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1284 programs should use their Gnulib counterparts.
1285 * doc/autoconf.texi (Particular Functions): Likewise.
1286 (Macro Names, testsuite Invocation): Replace uses of these
1287 obsolete macros with uses of non-obsolete macros.

1315 Fix Lex library problem reported to us by Julio Garvia.
1316 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1317 for the default, which the user can override.
1318 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1319 deal with LEXLIB.
1320 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1321 didn't work if some values were cached but not others. Test for
1322 broken lex libraries like native ia64-hp-hpux11.22; see
1323 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1324 work around the problem by preferring an empty LEXLIB to -lfl or
1325 -ll. Let the user set LEXLIB='' to indicate no library needed.
1327 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1328 * README: Likewise.
1329 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1390 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
1391 Also check for -Wpointer-arith.
1392 (WGET, WGETFLAGS, tgz-md5, tgz-sha1, bz2-md5, bz2-sha1):
1393 (xdelta-md5, xdelta-sha1, tgz-size, bz2-size, xd-size, rel-check):
1394 Remove.

1424 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
1425 64-bit preprocessor ints. Check for static initialization of
1426 long long. Remove unnecessary casts.
1428 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1430 * doc/autoconf.texi (Particular Programs): Mention that
1431 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1432 Reported by Alexandre Duret-Lutz.
1434 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1436 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1437 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1438 Bill Northcott in
1439 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
1441 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
1443 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
1444 pacify insanely picky compilers. Problem reported by Eric Blake.
1446 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
1447 longer supported by Sun.
1449 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
1451 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
1452 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1453 -Wundef -Werror". Problem reported by David Fang in
1454 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1455 * doc/autoconf.texi (Header Templates, Default Includes):

1457 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1458 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):
1459 (Present But Cannot Be Compiled, Preprocessor Symbol Index):
1460 Prefer #ifdef to #if.
1461 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prefer #ifdef to #if.
1462 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, _AC_FUNC_MALLOC_IF):
1463 (AC_FUNC_MKTIME, AC_FUNC_MMAP, _AC_FUNC_REALLOC_IF):

1470 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1471 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1472 this.
1474 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1476 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1477 problems with arg script text that doesn't end in newline, and
1478 with '-e a...'. Problems reported by Ralf Wildenhues.
1480 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1482 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1483 check for libXt by a check for libX11.
1485 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1487 * doc/autoconf.texi (config.status Invocation): Adjust according
1488 to last change.
1490 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1492 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1493 --help' should mention that `--version' outputs configuration
1494 settings. Report by Bruno Haible.
1496 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1498 Fix test suite failures reported by Pierre in
1499 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1500 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1501 the compiler created a file "b.out" when it didn't create anything
1502 at all.
1503 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1504 Discard stderr too, when invoking the test script.
1506 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1508 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1509 in the restoring of the werror flag.
1511 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1513 * doc/autoconf.texi (Volatile Objects): Be even a little
1514 less skeptical about "volatile", after discussion with
1515 Bruno Haible on bug-gnulib.
1516 (Limitations of Usual Tools): Warn about sed stripping
1517 leading white space from text. From Bruno Haible.
1519 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1521 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1522 compiler complains about it, even if things works after the
1523 complaint. Problem reported by Peter O'Gorman.
1525 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1526 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1527 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1529 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1531 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1532 after -R regardless of host. Patrick Welche reports that this
1533 fixes things on NetBSD 3.99.
1535 * NEWS: Recommend M4 1.4.5.
1536 * README: Likewise.
1537 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1538 * tests/tools.at (autom4te cache): Update wording of diagnostic
1539 to match M4 1.4.5.
1541 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1543 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1544 under AC_C_VOLATILE.
1545 (Volatile Objects): Be a little less skeptical about what
1546 "volatile" means. Derived from thoughts by Ben Pfaff in
1547 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1549 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1551 * doc/autoconf.texi: Fix some typos.
1553 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1555 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1556 more globally, since the 2006-06-30 patch didn't suffice. Problem
1557 reported by Keith Marshall. Also, don't bother with builddir2,
1558 since it shouldn't be needed any more.
1560 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1562 * doc/autoconf.texi (Generic compiler characteristics):
1563 Document AC_COMPUTE_INT. Fix wrong statements on Default
1564 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1566 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1567 (_AC_COMPUTE_INT): Add obsoletion warnings.
1568 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1569 AC_COMPUTE_INT.
1571 * NEWS: Document change.
1573 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1575 * doc/autoconf.texi (Volatile Objects): New section.
1577 * NEWS: Document previous change.
1579 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1581 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1582 Require that long long int be at least 64 bits wide. C99 requires
1583 this and enough programs depend on it so we should check for it.
1584 Bruno Haible reports in
1585 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1586 that long long int is 32 bits wide with some nonstandard compilers.
1587 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1589 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1591 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1592 to a nonexistent file, so that we don't have to worry about
1593 a local site configuration that doesn't use /usr/local.
1594 Problem reported by Keith Marshall in
1595 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1597 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1599 * doc/autoconf.texi: Be more consistent about using @acronym with
1600 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1601 quite right (it talked about "OSF/Tru64", even though the
1602 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1603 and it even mentioned "OSF 4"!) and at this point there's little
1604 reason to talk about OSF any more, since it died in 1994.
1605 (Specific Compiler Characteristics): Simplify example of
1606 negative-size array.
1607 (File Descriptors): Reorder to make the text flow better.
1608 Remove joke about "appreciate the various levels"; I didn't get it.
1609 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1610 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1611 (File Descriptors, Limitations of Usual Tools):
1612 Tone down the advice against renaming or removing open files.
1613 (Limitations of Usual Tools): Add a new section, on 'rm'.
1615 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1617 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1618 -lXt in LIBS, idea from Karsten Hopp; this was due since
1619 this change:
1621 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1622 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1623 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1624 (which belong to Xt, not X itself). See Debian bug 327655.
1626 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1628 * configure.ac (AC_INIT): Bump to 2.60a.
1629 * NEWS: Update.
1631 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1633 Version 2.60.
1635 * configure.ac, NEWS: Update.
1637 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1639 * config/texinfo.tex: Sync from upstream.
1641 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1642 quadrigraph correctly in traces.
1644 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1645 Fix typos.
1647 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1648 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1649 not defined.
1650 * doc/autoconf.texi (Changed Directory Variables): New node,
1651 to document the whole `datarootdir' business a bit better.
1652 * NEWS: Update.
1653 * tests/torture.at (datarootdir workaround): Extend test.
1654 Prompted by report by Alexandre Julliard.
1656 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1658 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1659 when using default mode of IBM C 6 for AIX. Problem and two-line
1660 fix reported by Larry Jones.
1662 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1664 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1665 about literal '${datarootdir}' if a definition is found in the
1666 output file.
1668 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1670 * NEWS: Use "M4" rather than "m4" when appropriate.
1671 Problem reported by Eric Blake.
1672 * doc/autoconf.texi: Likewise.
1673 Use @acronym around BSD, GCC, and GNU when appropriate.
1674 (Why GNU M4): Renamed from "Why GNU m4".
1675 (Redefined M4 Macros): Mention that Posix
1676 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1677 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1678 to int.
1680 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1682 * bin/autom4te.in (handle_output): Do not forbid the empty
1683 pattern.
1684 * tests/tools.at (autoconf: the empty token): New test.
1686 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1688 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1689 calls, so that we do not care whether they are LIFO or FIFO;
1690 in the m4_wrap, do not check which diversion is the topmost
1691 one, just check that the stack is balanced at the end.
1692 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1693 base diversion forever--pop the previous diversion before
1694 opening the new one; consequently, remove the m4_wrap call.
1695 * lib/autotest/general.m4 (AT_INIT): Likewise.
1696 * tests/m4sugar.at: Do not use
1697 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1699 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1700 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1702 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1703 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1704 Rework example of m4wrap token-pasting trouble so that it doesn't
1705 care whether it's LIFO or FIFO.
1706 Fix some "contrary to"s that are awkward in English.
1708 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1710 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1711 to `yes' instead of `int$1_t' if the type is found, for more
1712 consistent configure output (where $1 is the number of bits).
1713 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1714 Suggested by Bruno Haible.
1716 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1717 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1718 with system headers. Report by Bruno Haible.
1720 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1722 * config/config.guess, config/config.sub: Sync from upstream.
1724 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1725 in order to avoid picking up an older installed frozen m4sh.m4f.
1726 Besides an outdated shell startup, this could have been created
1727 by an earlier M4 version with incompatible frozen file format.
1729 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1731 * README: Recommend m4 1.4.4 instead of 1.4.3..
1732 * doc/autoconf.texi: Likewise.
1733 (Special Chars in Names): Say that $(.FOO) is portable, as
1734 suggested by Stepan Kasal.
1735 (Installation Directory Variables, Build Directories):
1736 (Automatic Remaking, Subdirectories, Fortran Compiler):
1737 (Making testsuite Scripts, Defining Directories):
1738 Quote variable usages better.
1739 (Making testsuite Scripts): Add clean-local rule to makefile
1740 snippet, by Eric Blake.
1741 (Installation Directory Variables): Fix table item font.
1742 Reword slightly to clarify. Generalize advice about
1743 not using special characters to include all file-related
1744 vars, not just VPATH.
1745 (Special Chars in Variables): Warn about special characters in
1746 $(srcdir) too.
1747 (Assignments): Clarify default-value example as suggested by
1748 Ralf Wildenhues in
1749 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1750 (Special Shell Variables): Note leading ./ or ../, as suggested
1751 by Eric Blake.
1752 (Limitations of Builtins): Under cd, warn about CDPATH.
1753 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1754 Ralf Wildenhues.
1756 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1758 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1759 `@var', for texi2html.
1760 (Systemology): Some more word wrapping, for DVI output.
1761 (autom4te Invocation): The short option for `--melt' is `-M',
1762 not `-m'.
1764 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1766 * doc/autoconf.texi: More formatting and English tweaks,
1767 many suggested by Ralf Wildenhues.
1768 Reword to avoid "@code{...}'s" and the like, since it's ugly
1769 with Emacs info mode. discontents -> woes.
1770 Put a few "will"s back. time stamp -> timestamp.
1771 side-effect -> side effect.
1773 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1775 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1776 Warn about $@ not persisting. Problem reported by Julien Danjou in
1777 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1778 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1779 Mention other special chars, too.
1781 2006-06-14 Eric Blake <ebb9@byu.net>
1783 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1785 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1787 * doc/autoconf.texi: Some systematic minor improvements, as
1788 follows. Use "makefile" when talking about makefiles
1789 generally (which might be named "makefile" or "Makefile" or even
1790 "foo.mk"), "Makefile" when talking about a specific makefile
1791 called "Makefile". This unclutters the text from weird quotes
1792 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1793 values" rather than "@var{foo}s" and similar constructs containing
1794 "}s". Use "Make rules" rather than "Makefile rules". Minor
1795 English-language improvements. Change the prefix "sub-" to "sub"
1796 and "re-" to "re".
1797 Put blank lines around examples more consistently.
1798 Avoid "rather" and "very" as intensifiers.
1799 Avoid "will" as an auxiliary.
1800 (Limitations of Make): Split this node into....
1801 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1802 (Leading _ in Macro Names, Backslash-Newline-Newline):
1803 (Backslash-Newline Comments, Long Lines in Makefiles):
1804 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1805 (obj/ and Make, make -k Status, VPATH and Make):
1806 (VPATH and Double-colon, $< in Explicit Rules):
1807 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1808 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1809 New nodes, resulting from splitup of Limitations of Make.
1810 All cross-references changed. Raise the top node from
1811 a section to a chapter, and all subnodes accordingly.
1812 Redo the introductory wording to match the new organization.
1813 (Installation Directory Variables): Use an example that is
1814 closer to what Autoconf actually does. Mention that VPATH's
1815 value should not contain metacharacters or white space.
1816 (Fortran Compiler): Fix a VPATH bug in an example.
1817 (Leading _ in Macro Names): Mention that this problem is no longer
1818 of practical concern.
1819 (VPATH and Make): Reword the advice to make it clearer
1820 that Autoconf and Automake support VPATH in non-GNU make, but
1821 many packages have bugs in this area.
1822 ($< in Explicit Rules): Refer to Build Directories rather
1823 than using a (non-VPATH-safe) example.
1824 (Automatic Rule Rewriting): Mention the sort of disaster that
1825 can ensue with Solaris-style rule rewriting with VPATH.
1827 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1829 * doc/install.texi (Compilers and Options): Weaken the
1830 suggestion to use GNU make for VPATH builds.
1832 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1833 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1835 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1836 in regular expression.
1838 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1840 * doc/autoconf.texi (Installation Directory Variables):
1841 Drop extra @samp from `@table @samp' item.
1842 (Limitations of Usual Tools): Comment fix.
1843 Do not nest @samp just to point to other table items.
1844 (Writing testsuite.at) <AT_CHECK>: The second argument to
1845 `@dvar' is already @samp'ed.
1846 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1847 do not use @var in the second argument.
1849 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1851 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1852 $as_shell.exe too. Problem reported by Andreas Buening in
1853 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1855 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1857 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1858 `unused variable' compiler warning, for `-Wall -Werror'.
1859 Reported by Jaap Haitsma in
1860 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1862 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1864 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1865 case the compiler dumps core. Problem reported for
1866 OpenServer 5.0.7 by Tim Rice in
1867 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1868 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1869 Likewise.
1871 2006-06-06 Tim Rice <tim@multitalents.net>.
1873 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1874 "ERROR" only shows up in "make check" output if there is an
1875 error.
1877 2006-06-06 Eric Blake <ebb9@byu.net>
1879 * tests/tools.at (automatically allowed tokens): Fix typo.
1881 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1883 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1885 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1886 typically overflows on x86 CPUs, even though the C standard
1887 requires otherwise.
1889 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1891 * configure.ac (AC_INIT): Bump to 2.59e.
1892 * NEWS: Update.
1894 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1896 Version 2.59d.
1898 * config/texinfo.tex: Sync from upstream.
1900 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1901 seen, invoke libtoolize with `--ltdl' argument.
1902 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1903 * NEWS: Update.
1904 Suggested by Eric Blake.
1906 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1908 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1909 reported by Ralf Wildenhues.
1910 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1912 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1914 * THANKS: Update.
1916 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1918 * doc/autoconf.texi: Modernize some of the references to Solaris.
1920 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1922 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1923 message issued by AC_REQUIRE.
1924 * tests/m4sugar.at: Check m4_require's error message.
1925 * tests/base.at: Check AC_REQUIRE's error message.
1926 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1927 to...
1928 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1929 AT_CHECK_M4.
1930 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1931 `expout' as the last parameter.
1932 * tests/tools.at: Adapt to the above change.
1934 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1936 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1937 information about race-free implementations of mkdir.

1941 * bin/autoreconf.in (help): Document M4 environment variable.
1942 * bin/autoconf.as (Usage): Likewise.
1943 * bin/autom4te.in (help): Likewise.
1944 * doc/autoconf.texi (autom4te Invocation): Likewise.
1946 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1948 * NEWS: GNU make now recommended for VPATH builds.
1949 Mention that some macros are now documented to be obsolescent.
1950 * doc/autoconf.texi:
1951 Prefer "current" to "modern" to describe
1952 currently-used (albeit perhaps old-fashioned) hosts.
1953 Mention which ancient features no longer need to be worried about.
1954 setgid -> set-group-ID
1955 setuid -> set-user-ID (these are the Posix terms)
1956 Fix some misuses of "only".
1957 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1958 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1959 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1960 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1961 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1962 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1963 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1964 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1965 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1966 Mention that these macros are obsolescent.
1967 (Installation Directory Variables): shall -> should
1968 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1969 Mention that it's now safe to use 3 and 4.
1970 (Limitations of Usual Tools): cp -r is now specified by Posix.
1971 Omit longwinded and obsolescent discussion of cp -f.
1972 Modernize discussion of expr, ls.
1973 (Limitations of Make): Modernize discussion of VPATH builds.
1974 Mention $? as a workaround in some cases.
1975 * doc/install.texi (Basic Installation):
1976 Mention "./configure; make; make install" first. Be more
1977 specific about why this file is generic. Remove unnecessary
1978 parens. Remove misleading "only". Remove obsolete advice
1979 about csh. Don't say "configure" takes awhile; say it
1980 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1981 and CC=c99 rather than CC=c89, as these are blessed by current
1982 Posix. Recommend GNU make if doing a VPATH build.
1984 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1986 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1987 examples involving shell prompts.
1989 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1990 and Paul Eggert <eggert@cs.ucla.edu>
1992 * doc/autoconf.texi (Here-Documents): Add details about the
1993 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1994 use "here-documents" instead of "here documents".
1996 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1998 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2000 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2002 * doc/autoconf.texi (File System Conventions): Warn about ":"
2003 anywhere in directory names.
2005 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2007 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2008 about quoting the case statement, just in case.
2009 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2010 was fixed in ksh93g; reported by Ralf Wildenhues.
2012 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2014 * doc/autoconf.texi (System Services): Do not document
2015 overriding EXEEXT via ac_cv_exeext=ext.
2016 (Particular Programs) <AC_PROG_MKDIR_P>:
2017 Document that ${MKDIR_P} understands --.
2018 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2019 comment.
2021 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2023 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2024 argument with leading hyphen. Problem reported by Paul Eggert.
2026 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2028 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2029 about quoting ac_try: quote all of it, if any of it seems suspicious.
2030 This means we don't have to worry about ${ or sed any more.
2031 Also, double-quote the case statement, to work around misuses via
2032 underquoting as reported by Ralf Wildenhues in
2033 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2034 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2035 undocumented and dangerous macro.
2036 Problem reported by Ralf Wildenhues in
2037 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2039 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2041 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2042 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2043 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2045 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2047 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2048 since evidently some packages rely on the old, broken behavior.
2049 Problem reported by Ralf Wildenhues in
2050 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2051 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2052 pre-2006-05-26 definitions, but leave in the comments that
2053 these macros are dangerous and should not be used.
2054 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2055 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2056 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2057 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2058 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2060 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2062 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2063 the use of 'tr', since this is our only use of 'tr'.
2065 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2066 and Paul Eggert <eggert@cs.ucla.edu>
2068 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2069 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2071 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2073 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2074 the output file in the `${datarootdir}' test.
2076 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2077 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2079 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2080 mention of `datarootdir' in the input file(s), but literal
2081 `${datarootdir}' in the output file, and we haven't warned yet,
2082 then warn as well: the user may have (erroneously) used
2083 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2084 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2085 * tests/torture.at (datarootdir workaround): Extend this test.
2086 * NEWS: Update.
2088 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2089 and Paul Eggert <eggert@cs.ucla.edu>
2091 * doc/autoconf.texi (autoheader Invocation): The first argument to
2092 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2093 alternatives and clear up the language a bit.
2095 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2097 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2098 ac_config_guess, ac_config_sub, ac_configure.
2099 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2100 Fix typo that prevented an unnecessary space from being removed.
2101 Problems reported by Ralf Wildenhues in:
2102 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2104 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2106 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2107 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2108 Don't use the term "thread-safe" to talk about mkdir race
2109 conditions, since the problem is more a process than a thread
2110 issue. Problem reported by Stepan Kasal in:
2111 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2112 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2113 the test for 'install' more closely. Look at MKDIR_P first.
2114 Look in the PATH, and at /opt/sfw/bin.
2115 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2116 Don't bother to try mkdir -p, since we already check mkdir --version;
2117 just look at the version number. (There's no easy way to check
2118 for race-free implementations.)
2119 * tests/tools.at (autoconf: subdirectories): Adjust to above
2120 changes, since MKDIR_P now might end in "/mkdir -p".
2122 * doc/autoconf.texi (autoheader Invocation): Mention that the
2123 first arg of AC_DEFINE_UNQUOTED must be a literal.
2124 Problem reported by Ben Pfaff in
2125 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2127 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2128 * doc/autoconf.texi (Special Chars in Variables): New section.
2129 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2130 (Installation Directory Variables): Quote $(datadir) better.
2131 (Limitations of Builtins): Describe some of eval's trickiness.
2133 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2134 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2135 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2136 in front of every arg, not just trailing args. Quote apostrophes.
2137 (_AC_EVAL_ECHO): New macro.
2138 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2139 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2140 removed.
2141 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2142 exposed by quoting of eval argument. Put the command on line line
2143 so it logs better.
2144 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2145 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2146 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2147 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2148 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2149 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2150 Use eval more safely.
2151 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2152 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2153 to be replaced.
2154 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2155 lines, exposed by quoting of eval argument.
2157 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2158 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2160 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2161 initialization of `ac_cv_exeext', do not override it if it was
2162 already set, unless it was set to `no', for compatibility with
2163 Autoconf-2.13, and comment this.
2164 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2165 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2166 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2167 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2168 Document that this test may be overridden by setting
2169 `ac_cv_exeext'.
2171 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2173 Revert these two patches:
2175 2006-04-06 Eric Blake <ebb9@byu.net>
2176 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2177 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2178 2006-04-01.
2180 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2181 Clean up _AC_COMPILER_EXEEXT* macros.
2182 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2183 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2184 ac_file to the name of the default output file and call
2185 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2186 initial `rm' of the candidate files...
2187 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2188 the same list in subsequent `rm' calls, and for the temporary
2189 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2190 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2191 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2192 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2193 no longer needed) by libtool. Make it a cache check.
2194 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2195 copied here by mistake.
2196 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2197 _AC_COMPILER_EXEEXT.
2198 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2199 _AC_COMPILER_OBJEXT directly.
2200 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2202 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2204 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2205 Fix description of how the buggy `sed' works.
2207 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2209 Sync from Automake:
2211 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2212 ENOLCK. Only mention `make -j' when applicable. Only raise
2213 fatal errors when `make -j' is involved. Improve error message.
2215 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2217 * doc/autoconf.texi (Here-Documents): We now know more about
2218 the variable expansion in here documents bug.
2219 Thanks to Tim Rice and Stepan Kasal.
2221 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2222 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2224 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2226 * tests/autotest.at (Multiline command from M4 expansion):
2227 No failure to be expected if the shell quotes newlines in
2228 commands in the `set -x' output. Report by Tim Rice.
2229 * THANKS: Update.
2231 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2233 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2234 expansion in the here-documents used by config.status, as that
2235 runs afoul of the Korn shell version M-12/28/93d bug described in
2236 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2237 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2238 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2240 2006-05-23 Jim Meyering <jim@meyering.net>
2242 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2243 Fix typo introduced with 2006-04-02 change. It reversed the sense
2244 of the test.
2246 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2248 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2249 ac_dB slightly, to save bytes in the script.
2250 Max out at 50 lines, rather than 96; this is more likely
2251 (though not guaranteed) to avoid obscure 'sed' failures.
2253 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2255 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2256 `tr -d -' as bad option argument. Work around this by deleting
2257 an unrelated character.
2258 Report by Tim Rice <tim@multitalents.net>.
2260 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2261 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2262 Stepan Kasal <kasal@ucw.cz>
2264 * doc/autoconf.texi (Particular Programs): Do not promise that
2265 we always prefer the GNU version of the program, and that we
2266 search according to PATH; both rules can have exceptions.
2267 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2268 AC_PROG_SED. Move descriptions of limitations
2269 to the Limitations of Usual Tools section.
2270 (Limitations of Usual Tools) <sed>: Mention script length
2271 limitations with Solaris /usr/ucb/sed.
2272 <grep>: Fix wording for empty alternative. Mention that -c and
2273 -l should not be combined, and that -E and -F should not be
2274 combined.
2276 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2277 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2279 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2280 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2282 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2284 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2285 AC_DEFINE is now passed to m4_pattern_allow.
2286 * NEWS: Mention that; likewise for AC_SUBST.
2287 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2288 the parameter to m4_pattern_allow.
2289 * tests/tools.at: Add a check for that.
2291 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2293 * lib/autoconf/status.m4: Fix typos.
2295 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2297 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2298 only the files that this macro generates.
2300 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2302 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2303 the HP-UX sed limitation of 99 commands, labels do not count.
2304 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2305 in the comment.
2306 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2308 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2310 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2311 Import the following fix from coreutils:
2313 2006-01-13 Jim Meyering <jim@meyering.net>
2315 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2316 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2317 not double-quote uses of that variable, to accommodate the rare
2318 case in which getmntent is available in none of the libraries
2319 checked. This happens at least on FreeBSD 5.0.
2321 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2323 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2324 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2325 some other programs unwisely rely on these undocumented vars.
2326 But put in warning comments about them.
2327 Problem reported by Ralf Wildenhues in
2328 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2329 * NEWS: Document that these variables are intended to go away.
2331 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2333 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2334 and set the language to C++ (analogous to the equivalent Fortran
2335 tests).
2337 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2338 * doc/autoconf.texi (C++ Compiler): Document it.
2339 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2340 * NEWS: Update.
2342 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2344 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2345 that caused config.status to generate 100-command sed scripts; the
2346 portable limit is 99.
2348 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2350 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2351 variable `ac_d' instead of `d' to avoid infringing namespace.
2352 Report by Ralf Menzel.
2354 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2356 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2357 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2358 * tests/tools.at (autoconf: subdirectories): New test, taken from
2359 the corresponding problem report by Ralf Wildenhues in:
2360 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2362 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2363 Quote some uses of shell variables if they might suffer unexpected
2364 globbing. This doesn't fix all instances of quoting problems that
2365 I found, just the easy ones that look safe.
2366 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2367 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2368 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2369 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2370 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2371 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2372 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2373 Likewise.
2374 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2375 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2377 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2379 * bin/autoreconf.in ($help): Reword according to the manual.
2380 Suggested by Olly Betts.
2382 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2383 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2385 * bin/autoreconf.in: Pass the directory argument to
2386 `require_configure_ac'. Fix comment.
2387 * tests/torture.at (Configuring subdirectories): Expose this.
2388 Reported by Olly Betts.
2390 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2392 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2393 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2394 Automake as follows:
2396 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2397 `$configure_in' instead of `configure.in', to preserve
2398 directory component.
2400 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2402 * config/config.guess, config/config.sub, config/texinfo.tex,
2403 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2405 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2407 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2408 test for C99 conformance; (bool) 0.5 is an integer constant
2409 expression, but (bool) -0.5 is not. Problem reported by Fedor
2410 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2412 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2414 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2415 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2416 Warn about obsolete install-sh files. Remove stray sentence
2417 fragment and fix cross reference.
2418 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2419 install -d; this undoes the 2006-05-10 change.
2420 (MKDIR_P): Mark with AN_MAKEVAR.
2421 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2422 that we don't require $INSTALL to be thread-safe. Move comments
2423 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2424 of AC_PROG_INSTALL. Output a message saying that we're checking
2425 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2426 MKDIR_P instead of AC_SUBST.
2427 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2428 Special magic for MKDIR_P, too.
2429 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2430 a dnl.
2431 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2433 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2435 Sync from Automake, as follows:
2437 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2438 * config/install-sh: Initialize IFS, so field splitting isn't
2439 turned off later.
2440 * config/mkinstalldirs: Likewise.
2441 * config/missing: Remove superfluous quotes. Replace all uses of
2442 `[' by `test', for consistency, and for..
2443 * config/missing (sed_minuso, sed_output): New variables.
2444 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2445 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2446 Fixes `missing' to detect `--output' for help2man. Fixes
2447 PR automake/483. Report by Dennis J. Linse.
2448 (autom4te): Document in `missing --help'.
2450 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2452 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2453 * config/install-sh: Don't use 'path' to talk about file names,
2454 as per GNU coding standards. Close a race condition reported by Ralf
2455 Wildenhues and Stepan Kasal. There is still a race condition
2456 on hosts that predate Posix 1003.1-1992, but we can't help this.
2457 Don't mishandle weird characters like space on pre-Posix hosts.
2458 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2459 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2460 AC_PROG_MKDIR_P from AS_MKDIR_P.
2461 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2462 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2463 earlier editions are not (including Automake 1.8.3).
2464 Do not suggest mkinstalldirs for thread-safety.
2465 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2466 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2467 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2468 presence of special characters and race conditions.
2469 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2470 in Autoconf's name space.
2472 2006-05-10 Bruno Haible <bruno@clisp.org>
2473 and Paul Eggert <eggert@cs.ucla.edu>
2475 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2476 from Automake with minor changes.
2477 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2479 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2481 * config/install-sh: Update to Automake CVS version, as follows:
2482 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2483 * lib/install-sh: Simplify the expr implementation of dirname.
2484 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2485 * lib/install-sh: Handle --, and diagnose unknown options.
2487 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2489 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2490 `./autom4te' to create `./testsuite', since the `all' target
2491 will ensure its presence, but `installcheck' should not create
2492 the uninstalled wrappers.
2494 * tests/torture.at (Unusual Automake input files): Skip if we
2495 detect automake < 1.8.
2497 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2499 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2500 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2501 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2502 * NEWS: Update.
2504 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2506 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2507 munge (multiple) white space and other oddities.
2508 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2509 single quotes in variable assignment.
2510 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2511 and similar failures by adding multiple spaces, tabs, and other
2512 special characters.
2513 Report and different test suggested by Francesco Romani
2514 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2516 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2517 single quotes, we only need to search for single quotes; this
2518 both simplifies the search pattern, and makes us less
2519 susceptible to `echo' variations for arguments not containing
2520 single quotes.
2521 (_AC_ARG_VAR_VALIDATE): Likewise.
2523 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2525 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2526 `$*' and IFS concatenation issue with traditional shells and
2527 bash-2.04. Report by Seanster@Seanster.com.
2529 2006-05-03 Bruno Haible <bruno@clisp.org>
2531 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2532 precisely which Mac OS X versions have the od problem.
2534 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2536 * doc/autoconf.texi: Use @option systematically.
2538 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2539 and Bruno Haible <bruno@clisp.org>
2541 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2542 about 'od'.
2543 (Integer Overflow): Mention the special case of integer division
2544 overflow.
2546 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2548 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2549 traditional shells like the Solaris one that do not use the
2550 first IFS character for assembling `$*'.
2551 Prompted by a related report from autoconf_bug@nro.ca.
2553 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2554 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2556 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2557 Mention more problems with the -e option.
2559 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2561 * NEWS: Typo.
2562 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2564 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2565 in URLs to improve DVI formatted output (requires texinfo 4.6).
2566 (System Services, Systemology, Shellology): Likewise.
2567 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2568 output.
2570 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2571 continuous text.
2572 (Runtime): Fix macro argument names to match description:
2573 `action-if-found' -> `action-if-true' and similarly.
2574 (Obsolete Macros): Likewise.
2575 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2576 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2577 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2579 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2581 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2583 * ChangeLog: Typo.
2584 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2585 DVI output.
2587 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2590 /bin/sh set unsorted output.
2591 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2592 * tests/local.at: Likewise.
2594 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2596 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2597 (Integer Overflow, Null Pointers, Buffer Overruns):
2598 (Floating Point Portability, Exiting Portably): New sections.
2599 (Writing Test Programs): Fix some langauge. Recommend exiting
2600 with status 1, not merely nonzero. Clarify exit declaration.
2601 (Run Time): Move C exit status stuff to new Exiting Portably section.
2602 (Systemology): Mention Posix and levenez. Update v7 reference.
2603 (Portable Shell): Mention the Posix shell.
2605 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2607 * bin/autoconf.as (me): Replace by as_me.
2609 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2611 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2612 since as_me isn't set yet.
2614 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2616 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2617 a few minor bugs in this area.
2619 * doc/autoconf.texi (Programming in M4sh): Comment out the
2620 documentation of AS_BASENAME, for now.
2621 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2622 (Limitations of Builtins) <basename>: Do not refer to
2623 AS_BASENAME.
2624 * bin/autoconf.as (me): Don't use AS_BASENAME.
2625 (dir): Remove the unused variable.
2626 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2627 AS_DETECT_REQUIRED. All uses changed.

2629 All uses changed.
2630 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

2632 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2633 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2634 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2635 (_AS_DIRNAME_PREPARE): Likewise.
2636 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2637 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2638 (AS_DIRNAME): Use "dirname --".
2640 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2642 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2643 of "run time" and "run-time" changed to "runtime", for consistency.

2646 * lib/autoconf/general.m4: Likewise.
2647 * lib/autoconf/headers.m4: Likewise.
2649 * doc/autoconf.texi (Run Time): Document the exit status situation
2650 with more accuracy and detail.
2652 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2654 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2655 Archive is not officially `GNU' any more. Update URL.
2656 (Defining Directories): Likewise
2657 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2659 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2661 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2662 newline from the `trap' code to finish `config.log'; the NetBSD
2663 /bin/sh resets the exit status after an empty command, as
2664 documented in doc/autoconf.texi.
2665 Reported by Dalibor Topic <robilad@kaffe.org>.
2667 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2669 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2670 Suggested by Bruno Haible.
2672 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2674 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2675 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2676 Instead, just list the shells that we know work.
2677 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2678 changed. Be more cautious about the _cv_ variable.
2679 * tests/tools.at (Syntax of the shell scripts): Check the
2680 _cv_ variable once, at first, to avoid an internal autoconf error
2681 when sh -n does not work.
2683 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2685 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2687 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2689 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2690 use ">&-" since we're only 99.999% sure that this is portable,
2691 and since the MinGW bug is fixed in a different way.
2692 * lib/autotest/general.m4 (AT_INIT): Likewise.
2694 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2696 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2697 before opening config.log, to avoid hitting a bug on MinGW.
2699 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2701 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2702 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2703 This works around a MinGW bug reported by Eric Paire.
2704 Make sure that all writes to the log file append to it,
2705 rather than possibly losing data.
2706 * lib/autotest/general.m4 (AT_INIT): Likewise.
2708 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2710 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2711 description.
2713 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2715 * NEWS: Update.
2717 * configure.ac (AC_INIT): Bump to 2.59d.
2719 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2721 Version 2.59c.
2723 * Makefile.maint (news-date-check): Do not require a leading `*'
2724 before the release date in NEWS.
2726 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2727 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2729 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2730 the instantiated file do not contain the string 'datarootdir'
2731 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2732 @mandir@, replace the reference '${datarootdir}' by the value.
2733 * tests/torture.at (datarootdir workaround): New test.
2734 * NEWS: Advertise this temporary fixup.
2735 Based on a patch by Bruno Haible, reported and analyzed by
2736 Paul Eggert and Noah Misch.
2738 2006-04-12 Eric Blake <ebb9@byu.net>
2740 * tests/autotest.at (Debugging a failed test): Fix comment.
2742 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2744 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2745 all the changes since 2006-04-07.
2747 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2749 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2750 succeeded, but `ln -s file dir' failed, take care to remove the
2751 leftover target before the next test, to prevent its spurious
2752 failure; also make sure `ln file dir' works before selecting it.
2753 Thanks to Keith Marshall for pointing this out.
2754 * THANKS: Update.
2756 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2757 assignments in `at_debug_args', so that we put them correctly
2758 in the `run' script.
2759 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2760 Reported by Eric Blake.
2762 2006-04-11 Eric Blake <ebb9@byu.net>
2764 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2765 top-level tests after micro-suite has been run. Used in...
2766 (Debugging a successful test, Debugging script and environment),
2767 (Debugging a failed test): ...these new tests. The first of these
2768 is fixed by...
2769 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2770 macro, split out from...
2771 (AT_INIT): ...here, so that using -d also generates a run script.
2772 Document that -d inhibits top-level logging.
2773 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2774 inhibits top-level logging; debug scripts are created.
2776 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2777 check.
2778 * tests/autotest.at (Empty test, Empty check): New test to check it.
2780 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2781 from gcc.
2783 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2785 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2786 the files if a problem appears. Make the empty *.at files
2787 read-only, too. Proposed by Ralf Wildenhues.
2789 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2791 * config/Makefile.am: Add comment to force updated Makefile.in.
2793 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2794 space only patch to this file, this patch causes the Makefile.in
2795 files that include freeze.mk to be updated, and thus have a
2796 newer time stamp again, which in turn makes a pristine CVS
2797 checkout have correct time stamps.
2799 * Makefile.maint (cvs-sv): New macro, to be used..
2800 (config.guess-url_prefix, config.sub-url_prefix)
2801 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2802 point to CVS text checkout of Gnulib files.
2803 (copyright-check): Bump current year.
2804 (announcement): Do not hard-wire `./announce-gen'.
2805 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2806 correctly.
2807 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2808 `chmod +x'.
2809 (wget_files): Update config.guess, config.sub, texinfo.tex by
2810 `wget-update', now that their URLs work again.
2812 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2814 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2815 Problem noted by Paul D. Smith.
2817 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2819 * doc/autoconf.texi: Remove unused words from word list.
2820 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2821 .x-sc_trailing_space: New files.
2823 * doc/standards.texi: Sync from gnulib.
2825 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2826 `LIBOBJDIR' as experimental.
2828 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2829 with a target directory; it's internally implemented as `cp'
2830 anyway, but since Autoconf advertises the possibility to use
2831 a target directory when LN_S is `ln -s', we need to find out.
2832 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2833 analyzed by Keith Marshall <keith.marshall@total.com>.
2835 * THANKS: Update.
2837 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2839 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2840 confdefs.h as-is. In general, if it has backslash-newline or the
2841 like, then it doesn't work either to sort or to remove empty
2842 lines.
2844 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2846 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2848 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2850 * lib/autom4te.in (Automake-preselections): Preselect
2851 _AM_SUBST_NOTMAKE.
2853 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2855 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2856 apostrophe within a single-quoted string, as this is the usual
2857 tradition and is easier to read than '"'"'. Don't rely on the
2858 shell treating "$/" like '$/'. Use a more-consistent indenting
2859 style for the trap.
2861 2006-04-09 Eric Blake <ebb9@byu.net>
2863 * tests/autotest.at (Backquote command substitution),
2864 (Multiline backquote command substitution): Remove mistaken
2865 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2866 applied...
2867 (Parenthetical command substitution, Multiline parenthetical
2868 command substitution): here.
2870 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2872 Import macros from gnulib (often changing their name).

2886 (Pointers): Add Gnulib URL.
2887 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2888 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2889 Gnulib section.
2890 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

2894 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2895 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

2900 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2901 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2902 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2903 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2904 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2905 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2906 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2907 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2908 (Coding Style). Don't mention m4_expand_once.
2909 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2910 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2911 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

2919 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2920 Catch a bug in an HP-UX C compiler.
2921 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2922 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

2926 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2927 New macros.
2929 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2930 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2932 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2934 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2935 of the warning introduced by the 2001-08-28 change.
2937 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

2940 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2941 variables shall be overriden by the cache.

2943 that contains braces.
2945 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2947 Revert the patch from 2006-04-01 and only improve
2948 _AS_DETECT_BETTER_SHELL:
2950 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2951 skip nonexistent directories.
2952 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2953 only shell candidates which exist.
2954 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2955 * lib/autotest/general.m4 (AT_INIT): No need to give three
2956 parameters to _AS_PATH_WALK.
2958 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2959 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2961 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2962 distinguish m4sugar macros.
2963 * tests/tools.at (autoupdating with aclocal and m4_include):
2964 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2965 test case by Noah Misch <noah@cs.caltech.edu>.
2967 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2969 Revert my change from 2006-03-17, in other words:
2970 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2971 and DUALCASE=1.
2972 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2973 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2974 it is set.
2976 2006-04-07 Eric Blake <ebb9@byu.net>
2978 * doc/autoconf.texi (Programming in M4sh): Document that
2979 AS_MKDIR_P exits the script on failure.
2980 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2982 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2984 * config/elisp-comp, config/install-sh, config/mdate-sh,
2985 config/missing, config/mkinstalldirs: Sync from Automake.
2987 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2988 from Automake.
2990 * doc/make-stds.texi: Sync from gnulib.

2994 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2995 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2996 2006-04-01.
2998 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2999 Eric Blake <ebb9@byu.net>,
3000 Paul Eggert <eggert@cs.ucla.edu>,
3001 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3003 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3004 whether `set' quotes correctly: redirect stderr of the tested
3005 `set', and use a subshell, for Ultrix; use `sed' instead of
3006 `grep' for zsh `set' which may write binary output; match only
3007 at the beginning of a line, to avoid false positives.
3008 In order to avoid false positives by unrelated variables with
3009 multiline content, put the dump algorithm in a subshell and
3010 unset all variables containing newlines (except some which are
3011 special to the shell). Warn about cache variables that are
3012 unset.
3014 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3016 * config/config.guess, config/config.sub, config/texinfo.tex:
3017 Sync from upstream.
3019 * tests/mktests.sh: Reword comments.
3021 * tests/mktests.sh: Only skip internal macros starting with
3022 `_AC_' or `__AC_'. Noted by Stepan Kasal.

3025 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3026 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3027 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3028 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3030 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3031 shell issue with double-quoted command substitutions of native
3032 commands.
3033 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
3034 Marshall.
3036 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

3042 (m4-check): Likewise.
3043 (sc_system_h_headers): Do not print rule on execution.
3044 (sc_tight_scope): Do not fail for non-existing `src' directory.
3045 (sc_changelog): Skip the Copyright footer.
3046 * lib/autoconf/lang.m4: Remove trailing space.
3048 * lib/autoconf/status.m4: More replacements to
3049 <tab><space> where this makes sense.
3051 2006-04-06 Stepan Kasal <kasal@ucw.cz>
3053 * tests/Makefile.am (maintainer-check-posix):
3054 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3056 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3057 ac_config_<foo>s again, sometimes normalized, sometimes not.
3058 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3059 (AC_CONFIG_COMMANDS): Do not do so here.
3060 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3061 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3062 2005-07-25 rewrite. Noticed by Noah Misch.
3064 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3065 _AC_PRESERVE_HELP_ORDER, ...
3066 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3068 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3069 inside m4_expand_once; it is redundant.
3071 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3072 for --help from Cygnus `configure.'
3074 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
3076 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
3077 on a patch proposed by Ralf Wildenhues.
3079 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3081 * lib/autoconf/status.m4: Replace <space>''<tab> with
3082 <tab><space> where this makes sense.
3084 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3085 Noah Misch <noah@cs.caltech.edu>
3087 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3088 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3089 * doc/autoconf.texi (Help Formatting): New node.
3090 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3092 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3094 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3095 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3096 lib/autoconf/types.m4, lib/autotest/general.m4,
3097 tests/mktests.sh, tests/torture.at: White space cleanup:
3098 remove some SPACE before TAB, or add quoting ('' or @&t@).
3100 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3102 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3104 2006-04-05 Eric Blake <ebb9@byu.net>
3106 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3107 empty test suite works.
3108 * tests/autotest.at (Empty test suite): Remove xfail.
3110 2006-04-05 Noah Misch <noah@cs.caltech.edu>
3112 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
3113 TAGS to ac_config_<foo>s.
3114 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3115 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3116 normalizing it, consistent it with previous releases.
3117 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3119 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3121 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3122 Use simplified args that Eric Blake originally suggested.
3124 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3126 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3127 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3128 Use 'comm' rather than N instances of grep; this also fixes a bug
3129 whereby substrings were incorrectly matched, causing us to not
3130 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3131 (exclude_list): Exclude empty macros.
3132 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3134 Use awk rather than grep -E or egrep, to avoid
3135 portability problems with regular expressions containing newlines.
3136 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
3137 Switch from grep to awk syntax.
3138 (ac_exclude_script): Renamed from ac_exclude_egrep.
3139 (au_exclude_script): Renamed from au_exclude_egrep.
3141 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3143 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3144 a subdirectory subject to Cygnus `configure'.
3145 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3147 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3148 report request when we have no AC_PACKAGE_BUGREPORT.
3150 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3152 * THANKS: Update.
3154 * tests/mktests.sh: Update copyright year in the header of the
3155 generated files.
3157 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3158 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
3159 typedef'ed restricted pointer, to catch a compiler bug on

3218 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3219 initial `rm' of the candidate files...
3220 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3221 the same list in subsequent `rm' calls, and for the temporary
3222 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3223 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3224 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3225 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

3305 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3306 switch all of them on and of when necessary. Fixes the bug when
3307 m4sugar macros (e.g., m4_define) were expanded after the first
3308 automatic update (e.g., after AC_PREREQ or AC_INIT).
3310 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3543 the obsolescent AC_HEADER_STDC.
3544 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

3562 HP-UX sed is 99 commands, not 100.
3563 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
3564 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
3565 newline for portability.
3566 * tests/torture.at (Torturing config.status): Also test 100

4005 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
4006 by the function rather than ignoring it.
4007 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
4008 comparing its address. Intel's interprocedural optimization was

4026 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4027 Stepan Kasal <kasal@ucw.cz>
4029 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4030 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4031 make its content writable before removing it. Remove an errorneous
4032 comment from the end, where the logs of the failed tests are copied
4033 to the main log file.
4035 2005-09-27 Stepan Kasal <kasal@ucw.cz>

4042 problems if the testsuite were running too fast.
4044 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4046 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

4058 suggested by Ben Elliston. Handle weird characters correctly.
4060 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4062 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4063 calls, so that the final expansion of this macro is shorter.
4064 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4065 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4066 the cleanup there. Use AS_VAR_* macros, to be more general.
4067 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4069 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4071 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

4089 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4091 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4092 in the example. Reported by Bruno Haible.
4093 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4094 "if $undefined_var;" succeeds with my shell.
4096 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4097 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4098 but change the m4_divert_text to m4_divert_once.
4100 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4102 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4103 Work around bug in Solaris /usr/xpg4/bin/awk.
4104 The bug is present in at least Solaris 8 through 10.
4106 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4108 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4109 some evil values and relying on the fact that $* concatenates the
4110 parameters by the first character from IFS.
4112 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4113 Stepan Kasal <kasal@ucw.cz>

4118 Update limitations about when to call AC_CONFIG_HEADERS.
4119 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4120 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4121 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4122 ``Configuration Actions''; fix their index entries.
4124 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4125 options correctly. Process N-M as M-N if M is smaller than N.
4126 Process ranges correctly so that N-N will run only N.
4127 Sort and uniquify the tests that will be run. If there is more
4128 than one test, reinsert the banners for the tests.
4129 * tests/autotest.at (Keywords): Unmark XFAIL.
4131 2005-08-23 Stepan Kasal <kasal@ucw.cz>

4134 before passing the macro name to AH_TEMPLATE.
4136 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4137 now opens log after option processing; in particular, --version
4138 and --help do not touch config.log.
4140 * Makefile.maint: Revert the change from 2005-08-12.
4142 2005-08-22 Stepan Kasal <kasal@ucw.cz>

4157 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4159 When building in place, set srcdir="."; suggested by Tim Van Holder.
4161 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4162 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4163 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4164 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

4181 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4183 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

4196 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4197 "<tab>" in comment, so that the point is understandable.
4199 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4201 Rewrite substantial part of lib/autoconf/status.m4.
4202 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4203 and CONFIG_COMMANDS are not processed in four separate loops.
4204 Instead, there is one main loop. This alows that the common code
4205 is expanded only once, thus config.status (and configure) is smaller.
4207 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4208 the AC_LIST_FILES and cousins macros are no longer used.
4210 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4211 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4212 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4213 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4214 contain the initialization, nor the for loop, nor the associated
4215 commands; all these go to ...
4216 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4217 _AC_OUTPUT_CONFIG_STATUS.
4218 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4219 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4220 (_AC_OUTPUT_FILE): The creation of the sed script ...
4221 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4222 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4223 _AC_OUTPUT_MAIN_LOOP.
4224 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4225 _AC_CONFIG_COMMANDS): Use ...
4226 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4227 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4228 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4229 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4230 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4231 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4232 ... new macros.
4233 (_AC_CONFIG_UNIQUE): Update.
4234 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4235 Replaced by this ...
4236 (_AC_LIST_TAGS): ... new common macro.
4237 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4238 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4239 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4240 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4241 this didn't belong to the `config commands' section.
4242 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4243 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4244 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4245 to the `config commands' section either.
4246 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4247 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4249 ... and many changes to the comments nearby.
4251 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4252 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4253 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4254 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4255 (#define header templates): The comment at the top of the generated
4256 header now includes the name(s) of the source file(s).
4258 Several unrelated small changes:
4260 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4261 parameter to AC_DIAGNOSE.
4262 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4263 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4264 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4265 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4266 with AU::AC_OUTPUT.
4267 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4268 in AC_OUTPUT doesn't double-quote it either.
4269 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4270 parameters.
4272 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4274 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4275 versions of Portland Group compiler produce single- and double-quoted
4276 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4277 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4279 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4281 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4282 This is a corrected version of yesterday's patch.
4284 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4286 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4287 path, too; insert a "===" to emphasize the line.
4289 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4290 ac_cv_build_alias to ac_build_alias.
4291 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4293 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4294 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4295 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4296 (AC_ARG_VAR): ... here.
4297 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4298 target_alias.
4300 Keep a list of all precious variables and process them with one simple
4301 for loop, instead of expanding all commands, or, OTOH, complicated
4302 processing of output of "set".
4303 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4304 variable names in new macro...
4305 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4306 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4307 a loop to assign all ac_env_* and ac_cv_env_* variables.
4308 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4309 to INIT_PREPARE.
4310 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4311 its value to shell variable ac_precious_vars and call
4312 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4313 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4314 _AC_ARG_VAR_VALIDATE.
4316 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4317 and the AC_SUBSTs ...
4318 (AC_INIT): ... here.
4320 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4321 the ac_subst_files section in config.log.
4323 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4325 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

4332 Fix problems reported by Nicolas Joly.
4333 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4334 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4335 They are generated by the Tru64 v5.1B shell.
4337 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4339 Fix my changes from 2005-07-01; reported by Noah Misch.
4340 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4341 description, the macro now accepts only a single tag.
4342 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4344 Fix cases when the varsions of Autoconf and Autotest don't match.
4345 Reported by Noah Misch.
4346 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4347 at_top_builddir, for compatibility with older autotest.
4348 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4349 is not set, use at_top_builddir, for compatibility with older
4350 versions of autoconf.
4352 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4354 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4355 Problem reported by Patrick Welche.
4357 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4359 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4360 sed substitution command, so that we allow | in program prefixes
4361 and program suffixes. (& is a problem anyway; we're not fixing
4362 that here.)
4363 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4364 configure_input, top_builddir, srcdir, etc.
4365 * lib/autotest/general.m4 (AT_INIT): Likewise, for

4368 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4370 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4371 for loop over config.site files using `set', to allow
4372 directory names containing IFS characters.
4374 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4376 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4377 directories with weird names. Apparently some people like living
4378 on the edge. However, improve the test that "pwd" actually does
4379 report a name for the working directory.
4380 * NEWS: Remove the claim that we test for funny chars in dir names.
4382 2005-07-01 Stepan Kasal <kasal@ucw.cz>

4395 (Generic Functions): Mention the Gnulib project.
4396 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4398 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4399 document to output the default config_* lists to config.status.
4400 Don't recognize option --file, if the functionality is not there.
4401 Likewise for --header; moreover, recognize --he and --h as shortcuts
4402 for --help in that case.
4404 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4405 matches the order of execution. No code changed.

4426 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4427 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4428 (AC_SUBST): Call it.
4429 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4430 the directory specific variables; but don't call it for configure_input.
4432 2005-06-28 Derek Price <derek@ximbiot.com>
4434 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4435 addition.
4437 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4439 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4440 directory have inherent problems with special characters like spaces,
4441 due to limitations in Make syntax. Problem reported by Alexandre
4442 Duret-Lutz.
4443 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4456 from Justace Clutter.
4457 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4458 variable into diagnostic. Make the diagnostic an error, not a warning,
4459 because we really don't support spaces and suchlike in dir names.
4460 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4461 Don't worry about backslashes in srcdir; it can't happen now.

4463 Simplify ac_optarg handling.
4464 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4472 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4474 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4475 that '\|' is not allowed in BREs; recommend using newline separated
4476 list of patterns instead of multiple -e options.
4478 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4480 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4488 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4489 b, t, r, w commands require single space, while : cannot have any.
4490 (Special Shell Variables): Fix sed code this in the example.
4491 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4492 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4494 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4495 expand to the empty list. Don't use two pairs of m4_changequote,
4496 it's not necessary.
4498 2005-06-20 Derek Price <derek@ximbiot.com>
4500 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4502 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4504 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4505 * doc/autoconf.texi:
4506 Don't mention Solaris versions so much, if a
4507 problem is common to all extant versions of Solaris. Say "SunOS
4508 4" instead of "SunOS" for SunOS 4.
4509 (awk): Mention more of the limitations of traditional Awk.
4510 (cat): Don't talk about cat -v.
4512 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4514 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4515 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4516 but the implementation is entirely different and is designed
4517 to be compatible with glibc strverscmp.
4518 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4520 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4521 on Mac OS X 10.4 reported by Peter O'Gorman in:
4522 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4523 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4524 Use shell builtins rather than 'expr', to work around expr bug.
4526 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4528 * doc/autoconf.texi: "filesystem" -> "file system".
4529 "behaviour" -> "behavior".

4534 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4535 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4537 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4538 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4539 to update the man page. That way, we don't have to check in new
4540 man pages every month.
4542 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4543 quotes and backslashes. Patch from Derek Price.

4552 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4553 -u, since it outputs chatter if the input files are the same.
4554 Problem reported by Ralf Menzel.
4556 2005-06-08 Derek Price <derek@ximbiot.com>
4558 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4559 renaming them since they are about to be redefined anyhow.
4561 2005-06-08 Derek Price <derek@ximbiot.com>
4563 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4564 redefined M4 macros to this node. Document m4_include & m4_sinclude.

4576 might get inadvertently cut-and-pasted into user code.
4577 Remove example of autom4te usage that doesn't seem to work now.

4589 follows its own advice about quoting better.
4590 Reword to avoid some formatting glitches.
4591 * doc/installt.exi: Reword to avoid some formatting glitches.
4593 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4594 Tru64 ksh pattern matching bug. Reported against Libtool by
4595 Albert Chin <libtool@mlists.thewrittenword.com> and
4596 Nicolas Joly <njoly@pasteur.fr>.
4598 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4600 m4_cdr of one-member list was [[]] (one-member list containing an
4601 empty string) instead of [] (an empty list. Callers were skewed to
4602 match this misbehaviour. As a consequence of this:
4603 - m4_foreach([x], [], [foo]) expanded to `foo', while
4604 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4605 This bug has been fixed:
4607 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4608 expand to an empty string; print error msg if called without
4609 an argument list.
4610 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4611 misbehaviour; handle [] and [[]] correctly.
4613 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4615 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4617 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4619 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4621 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4622 swallow records with more than 99 fields.
4623 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4624 parse the long line.
4626 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4628 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4629 swallow literals longer than 399. Reported by Ralf Wildenhues.
4630 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4631 to workaround this limitation.
4633 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4635 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4636 to gfortran, and make these the first two compiler names
4637 checked (following the general autoconf preference for gcc).
4639 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4641 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4642 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4643 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4645 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4647 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4648 expression of unbounded size when processing the --list
4649 option. This runs afoul of a limit of 399 bytes per regular
4650 expression on AIX. Problem reported by Ralf Wildenhues.
4652 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

4655 * doc/autoconf.texi (Particular Headers): Reword example
4656 for multiline stdbool replacement.
4657 (Setting Output Variables): Reword text a bit. Don't
4658 give all the details about |#_!!_#|.
4659 Reword description of line replacement.
4661 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4663 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4664 now contain newlines, and substituted files must be referenced on
4665 a line alone; the sed scripts to substitute them are now very
4666 different.
4667 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4668 commands can be put in a sed script portably.
4669 * doc/autoconf.texi (Setting Output Variables): Document above
4670 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4671 use of multiline substitution.

4681 * tests/local.at: Don't attempt to check for negated character
4682 classes in shell scripts. The test was too brittle.
4684 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4686 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4687 * doc/autoconf.texi (Limitations of Builtins): Document this
4688 limitation.
4690 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4692 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4693 common code; used in many places in the tree.
4694 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4695 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4697 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4699 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4700 messages when ac_unique_file is not found.
4701 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4702 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4703 commands, for consistency with AC_MSG_ERROR and such.
4705 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4707 * bin/Makefile.am: Merge the two rules for creating scripts.

4715 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4717 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4718 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4719 (ac_top_builddir): ... this ...
4720 (ac_top_build_prefix): ... to this; the old name is also kept, for
4721 backward compatibility.
4722 (ac_top_builddir_sub): New variable, without the trailing slash,
4723 always nonempty.
4724 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4725 * doc/autoconf.texi (Configuration Actions): Rename
4726 ac_top_builddir to ac_top_build_prefix.
4727 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4728 at_top_builddir to at_top_build_prefix.

4733 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4734 of confdefs.h .
4736 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4738 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4739 argument to m4_foreach. I guess it was necessary in the past,
4740 but I think it's a no-op now.
4742 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4744 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4745 ``cat <<_ACEOF'' commands to one.
4746 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4747 * lib/autoconf/status.m4: On various places, use expr instead of
4748 ``echo|sed.''
4749 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4750 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4751 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4752 a range.
4753 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

4759 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4760 as on 2005-05-02.
4761 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4762 Mention LIBOBJDIR.

4821 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4823 * doc/autoconf.texi (Autoconf Language): Be more precise about
4824 quoting rules. Problems noted by Stepan Kasal.
4825 Also, throughout this document, be more careful about white space.
4826 "blank", "white space", and "space" all have different meanings
4827 and we should be careful to say what we mean.
4829 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4831 Fix C++ related problems reported by Werner Lemberg.
4832 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

4878 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4879 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4880 comment and reduce m4_default([foo], []) to [foo].
4881 (m4_strip): Update the explanation.
4883 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4885 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4886 Remove core.conftest.* too; it's generated by Tru64 5.1.
4887 Problem reported by Jennis Pruett.
4888 * lib/autoconf/functions.m4
4889 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4890 Don't bother to remove core files; AC_RUN_IFELSE should do that
4891 for you.
4893 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4895 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

4941 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4943 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4945 * NEWS: The configure command now warns you if you attempt to use
4946 a directory whose name contains a special character like space,
4947 newline, or "\".

4963 ac_pwd, and quote srcdir.
4964 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4966 * doc/autoconf.texi: Fix some systematic formatting problems.
4967 ".)" needs a following @: if not at the end of a sentence, and
4968 similarly for "!)". "etc." should be preceded by a comma.
4969 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4971 2005-03-22 Bruno Haible <bruno@clisp.org>
4973 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4974 argument is often called 'build-aux'.

4978 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4979 macro AC_TRY_LINK is obsolete.
4980 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4981 `AC_CONFIG_FILES'.
4983 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4985 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4986 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4987 from a Common Lisp's `cl'.
4988 (AC_PROG_CXX): Behave according to the documentation: don't
4989 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4990 make the variable CCC precious; use `cl.exe', not `cl'.
4992 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4993 Alexandre Duret-Lutz <adl@gnu.org>
4995 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4996 /dev/null, as "configure" shouldn't read stdin, and this insulates
4997 us from problems (e.g., when testing for "cl"). Also, do this
4998 redirection before invoking "hostname" or "uname", and keep the
4999 original input stream available via...
5000 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5001 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5002 bother with "</dev/null" since it's now done at the top of
5003 'configure'.
5004 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5005 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5006 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

5011 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5013 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5014 newline if neither \c nor -n work, as that would output two
5015 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5017 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5019 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5020 This causes that any required macros inside will get before the if.
5021 * doc/autoconf.texi (autom4te.cache): A typo.
5023 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5025 Undo previous change, except keep the change to
5026 lib/autoconf/programs.m4 that replaced grep with shell
5027 pattern-matching. This is because net-snmp configure reads stdin.
5028 Reported by Noah Misch.
5030 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5032 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5033 from /dev/null, as "configure" shouldn't read stdin, and this
5034 insulates us from problems (e.g., when testing for "cl").
5035 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5036 before invoking "hostname" or "uname".
5037 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5038 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5039 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5040 "</dev/null" since it's now done at the top of 'configure'.
5041 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5042 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5043 Also, replace grep with shell pattern-matching, to save a process.
5045 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5047 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5048 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5049 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5050 compiler.
5052 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5054 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5055 grep -q isn't portable. Improve grep -s explanation.
5056 Problem reported by Dan Manthey.
5058 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5060 * doc/autoconf.texi (Special Shell Variables): Clarify
5061 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5063 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5065 * doc/autoconf.texi: Use @acronym for DJGPP.
5066 Fix some @code's that should have been @env's, and vice versa.
5067 Sort environment variable names.
5068 Mention that shells no longer inherit IFS.
5069 Don't recommend PATH_SEPARATOR=';' so strongly.
5070 Mention that $RANDOM might expand to the empty string.
5071 "symlink" and "soft link" -> "symbolic link".
5072 Improve mktemp description (reported by Bruno Haible).
5074 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5076 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5077 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5078 Likewise.
5079 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5080 Likewise.
5082 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5084 * NEWS: Mention AT_COPYRIGHT.
5086 * tests/local.at (AT_CMP): Use diff directly on input files rather
5087 than copying them.
5089 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5090 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5092 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5093 and Paul Eggert <eggert@cs.ucla.edu>
5095 * tests/autotest.at (Empty test suite): New test.

5102 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5103 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5104 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5105 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5106 (Standard regular expressions): New test.
5107 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5108 excess test name quoting.
5109 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5110 CPPFLAGS to `configure' instead of setting it in `configure'.
5112 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5113 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5114 on some platforms.
5116 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5117 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

5125 * tests/c.at (Extensions): Do not exit early.

5145 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5147 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5148 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5150 Try not to generated lines of unlimited length, as POSIX places a
5151 2047-byte limit on line length of portable text files.
5152 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5153 Use newline as a separator, not space.
5154 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
5155 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5156 space.
5158 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5160 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5161 as_func_*. Add test to check whether positional parameters
5162 are restored after function return.
5164 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5166 * doc/autoconf.texi (Special Shell Variables): Mention _,
5167 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5168 if they contain a lower-case letter. The DUALCASE problem was
5169 reported by Ralf Wildenhues.
5171 * bin/autoconf.as: Don't exit with status 0 after write failure
5172 with --help or --version.
5173 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

5179 Unicos 9 sed limitations.
5180 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

5184 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5186 * man/Makefile.am (.x.1): Go back to the simple solution, but take
5187 care to echo the commands, so the user knows what's going on.
5188 Modified from a suggestion by Stepan Kasal.
5190 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

5198 Based on a proposed patch by Ralf Wildenhues.
5200 * man/Makefile.am (.x.1): Make sure the required generated files
5201 are up to date. Problem and original solution proposed by Stepan Kasal.
5202 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
5203 implicit-man-prerequisites): New rules, used by the above.

5209 2005-01-29 Stepan Kasal <kasal@ucw.cz>
5211 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5212 Update the long comment explaining it.
5214 m4_require no longer writes an ``is required by'' line to the
5215 execution stack. It contains only one bit of non-redundant
5216 information: that the macro was required, not called. And even
5217 this bit is useless in most situations: have you ever met a macro
5218 which both calls and requires the same macro?
5220 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5221 (_m4_defun_pro_outer): ... only via this macro, for the outermost
5222 macro.
5223 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
5224 (m4_expansion_stack_pop): Remove the misplaced comment.
5225 (m4_require): Don't put the ``is required by'' line to the
5226 execution stack; slightly improve the out-of-a-defun error message.
5227 (_m4_divert_grow): New macro, counter for the temporary diversions.
5228 (_m4_require_call): Use it.
5229 * tests/m4sugar.at (m4_require): Expect output without the
5230 ``is required by'' messages.
5232 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5234 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5235 rather than x for expr.
5237 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5238 this is safe.
5239 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
5240 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

5250 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
5251 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
5252 from masters, so that FileUtils.pm's update_file provide --force
5253 support.
5254 * bin/autoheader.in: Pass $force to update_file so that
5255 config.h.in is always recreated when --force.
5257 2005-01-24 Stepan Kasal <kasal@ucw.cz>
5259 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
5261 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5263 * doc/autoconf.texi (Limitations of Builtins): Clarify that
5264 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
5266 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5268 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5269 Warn about newline stripping in `` and $(). Update Solaris
5270 version to 9.
5271 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5272 X insulates us from future changes to Posix.
5273 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5274 stripping.
5276 2005-01-19 Stepan Kasal <kasal@ucw.cz>
5278 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
5279 you cannot use AC_DEFINE to define macros containing `[' or `]'.
5281 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
5283 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
5284 in Solaris 8 join. Problem reported by Tomohiro Suzuki on

5294 ulongval to be static, to avoid unwanted GCC warning. Problem
5295 reported by Michael Jennings via Daniel Reed; see
5296 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
5298 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5300 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
5301 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
5302 datadir, infodir, and mandir. Adjust argument parsing code.
5303 (_AC_INIT_HELP): Update help text.
5304 * doc/autoconf.texi (Installation Directory Variables): Document
5305 new variables.
5307 2005-01-04 Noah Misch <noah@cs.caltech.edu>
5309 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
5310 not seem to work, assume it does set $(MAKE).
5311 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
5313 2005-01-03 Stepan Kasal <kasal@ucw.cz>
5315 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

5321 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
5322 (_m4_divert_n_stack): New macro; the expansion is
5323 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5324 otherwise.
5325 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5326 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5327 stored in _m4_divert_diversion or _m4_divert_dump.
5328 (m4_divert_pop): When the parameter is given, compare the symbolic
5329 name with the last diversion pushed on the stack. Previously, the
5330 current diversion was compared with the numeric value of the
5331 diversion given as the parameter.
5332 (m4_require): If the macro hasn't been expanded yet, call ...
5333 (_m4_require_call): this new macro.
5335 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5337 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

5366 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
5367 signals that the package uses Automake; a `Makefile.am' is typical but
5368 not essential. Reported by Magnus Therning.
5369 * tests/torture.at (autoreconf.): New banner.
5370 (autoreconf and non-AC configure): Rename to `Non-Autoconf
5371 AC_CONFIG_SUBDIRS'.

5388 If the variable to set is already set, set ac_cv_path_$1
5389 to the preset value so caller can assume ac_cv_path_$1
5390 is available. (trivial change)
5392 2004-12-27 Noah Misch <noah@cs.caltech.edu>

5409 <read>: New entry. Mention non-availability of -r.
5411 2004-12-21 Akim Demaille <akim@epita.fr>
5413 * lib/autotest/general.m4 (AT_LINE): Don't add srcdir here, to
5414 avoid cluttering displayed messages. Rather, prepend srcdir where

5640 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

5759 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

5881 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5883 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5884 with pdksh, too. Problem reported by Patrick Welche via
5885 Gary V. Vaughan.
5886 * doc/autoconf.texi (Shellology): Note that set -o posix is
5887 useful for pkdsh, too.
5889 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5891 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5892 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5893 Don't fail if ENV or BASH_ENV is readonly.
5894 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5895 etc. are read only. Problem reported by Ludovic Courtes.
5897 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5899 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5900 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5901 (trivial change)
5903 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5905 * doc/autoconf.texi (File System Conventions): Warn about
5906 names like "aux". Problem reported by Eric Blake.
5908 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5909 by zero instead of array size, so that we can use any arithmetic
5910 constant expression (instead of requiring an integer constant
5911 expression). This allows us to test expressions like DBL_MAX <
5912 LDBL_MAX, which didn't conform to the C standard using the old
5913 method.
5914 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5915 now that we can do floating-point tests at compile time.
5917 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5919 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5920 and LDBL_EPSILON, as the resulting expression isn't an
5921 integer constant expression and violates the C standard.
5922 Problem reported by Nelson H. F. Beebe. Also, check
5923 for "L" suffix, and check that long double doesn't have
5924 worse range or precision than double, that mixed-mode
5925 arithmetic doesn't generate a diagnostic, that double
5926 constants fit in long double.
5928 2004-06-03 Kevin Ryde <user42@zip.com.au>
5930 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5931 malloc(0) and realloc(NULL,size).
5933 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5934 Bob Proulx.
5936 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5938 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5939 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5940 by Jim Meyering.
5942 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5944 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5945 can be rewritten using if-then-else. Suggested by Bruno Haible.
5947 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5949 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5950 Problem reported by Stepan Kasal.
5952 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5954 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5955 change). Patch reported by Ralf Wildenhues in
5956 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5958 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5959 function F exists if the compiler and linker let you compile an
5960 expression like (F != 0). Recent versions of GCC optimize away
5961 the reference to F in that case, since every function address must
5962 be nonzero, so the link succeeds even if F does not exist.
5963 Problem reported by Manu in
5964 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5966 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5967 "Unix". Many uses changed.
5968 (Limitations of Builtins): Explain better why the ! command isn't
5969 portable.
5971 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5973 * lib/autom4te.in (Automake-preselections): Preselect
5974 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5976 2004-05-19 Kevin Ryde <user42@zip.com.au>
5978 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5979 referencing AC_FUNC_STRERROR_R.
5981 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5982 note pessimistic assumption when cross compiling.
5984 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5986 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5987 (until 2004) invoked subcommands with sh -e, contra POSIX.
5988 Reported by Kevin Ryde.
5990 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5992 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5993 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5994 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5995 `test -f " /usr/bin/grep"', which _always_ failed.
5996 (AC_PROG_SED): Ditto bogus PATH fix.
5997 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5998 requires that grep correctly supports _multiple_ `-e' options, rather
5999 than stating only that grep should accept `-e'.
6001 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6003 Port to C99, which requires that 'exit' be declared.
6005 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6006 to ensure that stdlib.h is included.
6007 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6008 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6009 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6010 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6011 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6012 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6013 when using 'exit' in a test; C99 requires that 'exit' be declared.
6015 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6017 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6018 now prefers 'grep' implementations that accept -e.
6019 (Limitations of Usual Tools): Describe problems of traditional
6020 egrep and fgrep with long input lines, and of traditional grep
6021 with -e.
6022 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6023 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6024 All callers changed. Append /usr/xpg4/bin to the PATH, for
6025 Solaris.
6026 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6027 the user with complaints about multiple -e options.
6028 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6029 Define it with AC_PROG_GREP.
6030 * configure.ac (AC_PROG_GREP): Add.
6031 * lib/freeze.mk (GREP): New macro.
6033 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6035 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6036 a possible candidate only after all others fail, rather than
6037 consulting it first. This improves backward compatibility by
6038 better reflecting the way shell selection occurred in previous
6039 versions of Autoconf, and should help to avoid triggering latent
6040 problems in other packages, such as the one in Automake where zsh
6041 is not handled robustly:
6042 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6043 Although it is not Autoconf's responsibility to work around
6044 problems in Automake, it nevertheless makes sense to avoid
6045 introducing unnecessary incompatibilites.
6047 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6048 Gary V. Vaughan <gary@gnu.org>
6050 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6051 how deeply nested we are when a suitable tool is found, set the
6052 ac_path_TOOL_found flag.
6053 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6054 nested we are in this macro. Break out of all 3 nested loops if
6055 ac_path_TOOL_found is set.
6057 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6059 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6060 of the _AS_PATH_WALK loop too if GNU flavor is found.
6062 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6064 * doc/autoconf.texi (Limitations of Make): Update documentation
6065 for `$<'. New entry `Long lines', based on a report from Simon
6066 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6067 paragraph about DJGPP, based on a mail from Richard Dawe.
6069 2004-04-20 Paul Eggert <eggert@twinsun.com>
6071 * tests/c.at (C keywords): Don't assume that GCC supports
6072 "restrict" and "inline", as sufficiently-old GCC versions do not
6073 (also, GCC configured to be in pedantic C89 mode does not).
6074 Problem reported by Sumit Pandya in:
6075 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6077 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6078 consider -g to work if it generates warnings when plain compiles
6079 don't. Problem reported by Braden McDaniel in:
6080 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6082 * doc/autoconf.texi (Slashes): New section, to document a problem
6083 reported by Jim Meyering in:
6084 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6086 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6087 linker output files before linking, to work around IRIX 6 linker bug.
6088 Problem reported by Rainer Orth in:
6089 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6091 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6093 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6094 best tool so far counter rely on the tool path variable name to
6095 avoid checks for one tool being affected by the results of running
6096 the length check on a previous tool.
6098 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6099 match expression argument, as different greps have different
6100 regular expression flavours.
6101 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6102 literals.
6103 (AC_PROG_EGREP): Pass 'EGREP$'.
6104 (AC_PROG_GREP): Pass 'GREP$'.
6106 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6108 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6109 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6111 2004-03-29 Paul Eggert <eggert@twinsun.com>
6113 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6114 Types, Specific Compiler Characteristics, System Services,
6115 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6116 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6117 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6118 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6119 Likewise.
6120 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6121 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6122 AC_TYPE_OFF_T): Likewise.
6123 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6124 Likewise.
6126 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
6127 pacify libtool 1.5.2. Fix quoting problems in sed command.
6129 2004-03-28 Paul Eggert <eggert@twinsun.com>
6131 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6132 now defines HAVE_DECL_TZNAME if it is declared, when
6133 HAVE_STRUCT_TM_TM_ZONE is not defined.
6134 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6135 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6136 for HAVE_TZNAME.
6138 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6140 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6141 superfluous backslashing of quotes (") in sed expressions;
6142 thanks to Paul Eggert.
6144 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6146 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6147 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6148 H. F. Beebe for the bug report.
6150 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6152 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6153 quoted -cmdline argument in Portland Group compiler (bug
6154 reported by Jeffrey J. Barteet).
6156 2004-03-25 Kevin Ryde <user42@zip.com.au>
6158 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6159 (Run Time): ... here, where it's now mentioned.
6161 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
6163 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
6164 inherits from language Autoconf-without-aclocal-m4.
6165 (Customizing autom4te): Adjust example; the cache must now be
6166 disabled for language Autoconf-without-aclocal-m4.
6168 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
6169 Nathanael Nerode <neroden@twcny.rr.com>

6180 AC_CHECK_TOOLS.
6181 (Specifying Names): Document the reason for these future
6182 behavioral changes.
6183 * tests/mktests.sh: Do not generate tests for the
6184 new macros.
6185 * NEWS: Document these changes.
6187 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6188 they make TeX hang up.
6190 2004-03-15 Paul Eggert <eggert@bogus.example.com>
6192 * NEWS: New macro AC_CHECK_ALIGNOF.
6193 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6194 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6195 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6196 vowel.
6197 (AC_CHECK_ALIGNOF): New macro.
6198 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6199 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
6200 those for sizeof.
6202 2004-03-03 Paul Eggert <eggert@twinsun.com>
6204 * bin/Makefile.am (edit): Don't use $< in a context where
6205 POSIX doesn't require support for it. Use $@.in instead.
6206 Problem reported by Anthony N. Frasso in
6207 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6208 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6210 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6212 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6213 from the next generation of Libtool.

6236 AC_SUBST provides no portable way to escape literal newlines.
6238 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6239 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6240 Darwin uses -lcrt2.o and there's little point to cataloging all
6241 the system variants. Partial fix reported by Andreas Waechter in:
6242 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6243 for bug reported by Nelson H. F. Beebe in:

6255 * bin/autoupdate.in: Define __file__ so that warnings
6256 refer to the correct file.
6257 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
6258 the behavior of the third argument.
6259 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6260 correctly the behavior of the third argument. Document
6261 what the three macros that AU_DEFUN defines do. Fix
6262 warning message when the third argument includes $0
6263 (reported by Alexandre Duret-Lutz).
6265 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6266 Eric Sunshine <sunshine@sunshineco.com>
6267 Paul Eggert <eggert@twinsun.com>
6269 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6270 (AS_INIT): Output shell initialization there. Removed optional
6271 parameter. Expand _AS_SHELL_FN_SPY.
6272 (AS_INIT_WITH_SHELL_FN): Removed.
6273 (_AS_SHELL_FN_SPY): New macro.
6274 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6275 macros.
6276 (AS_SHELL_SANITIZE): Remove loop to find better shell
6277 and documentation for the parameter.
6278 (_AS_DETECT_BETTER_SHELL): Move it here.
6279 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
6280 (_AS_RUN): Move it here, support testing with eval.
6281 (AS_REQUIRE_SHELL_FN): Require shell functions when
6282 it is used.
6283 (_AS_LINENO_WORKS): Put around braces, we do not
6284 trigger the bash bug anymore.
6285 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6286 use AS_INIT_WITH_SHELL_FN.
6287 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6289 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6291 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
6292 * doc/autoconf.texi: Don't say that the third parameter
6293 is broken.
6294 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
6295 (AU_DEFUN): Honor the third parameter, create autoupdate
6296 macros with AU_DEFINE.

6311 of autoupdate.
6313 2004-01-28 Paul Eggert <eggert@twinsun.com>

6316 copyright years.
6317 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6318 2003 (except 1997) to the list of copyright years. This undoes
6319 the 2003-05-22 change, which removed the older years from the list.

6322 2004-01-27 Gary V. Vaughan <gary@gnu.org>
6323 Albert Chin-A-Young <china@thewrittenword.com>
6325 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
6326 grep or ggrep program in PATH that accepts as long lines as
6327 possible.
6328 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6329 AC_PROG_GREP.
6330 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6331 egrep and fgrep respectively if $GREP -E/-F don't work.
6332 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6333 _AC_PROG_GREP, and AC_PROG_SED.
6334 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6335 longest input length accepted by a command.
6336 (AC_PROG_SED): Use it.
6337 * doc/autoconf.texi (Particular Programs): Document the changes.
6338 * NEWS: Updated.
6340 2004-01-27 Paul Eggert <eggert@twinsun.com>
6342 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
6343 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6344 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
6345 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6347 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6348 bin/autoconf.in, config/Makefile.in, config/config.guess,
6349 config/config.sub, config/install-sh, config/mdate-sh,
6350 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,

6362 sources.
6364 2004-01-26 Paul Eggert <eggert@twinsun.com>
6366 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6367 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6368 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6369 not <inttypes.h>. Problem reported by Tim Mooney in
6370 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6371 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6372 Likewise.
6374 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6375 otherwise "make check" fails because it forbids cmp (I guess
6376 because cmp treats files as binary on DOS-like systems).
6378 * tests/mktests.sh: Update copyright date to 2004, since some tests
6379 have changed in 2004.
6381 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6383 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6384 non-truncating sed or gsed program in PATH.
6385 * tests/acprograms.at: Add it.
6386 * doc/autoconf.texi (Particular Programs): Document it.
6387 * NEWS: Updated.
6389 2004-01-15 Paul Eggert <eggert@twinsun.com>
6391 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6392 -std1 disables some useful extensions on Tru64. Problem reported
6393 by N. Lichtmaier in
6394 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6396 2004-01-14 Paul Eggert <eggert@twinsun.com>
6398 * doc/autoconf.texi (Programming in M4sh): Document that
6399 AS_MKDIR_P succeeds if the destination is a symbolic link
6400 to an existing directory.
6401 (Limitations of Usual Tools): Note that mkdir -p might not
6402 succeed on symlinks to directories.
6404 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6406 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6407 * bin/autoheader.in: Grammar fix in message.
6408 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6409 Test for dir before calling mkdir -p. (trivial changes)
6411 2004-01-13 Eric Blake <ebb9@byu.net>
6413 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6414 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6416 2004-01-10 Jim Meyering <jim@meyering.net>
6418 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6420 2004-01-09 Paul Eggert <eggert@twinsun.com>
6422 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6423 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6424 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6425 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6426 AC_COMPILE_IFELSE, since we now assume our caller invokes
6427 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6428 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6429 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6430 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6432 2004-01-07 Paul Eggert <eggert@twinsun.com>
6434 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6435 `"'...'"`, as it's confusing (and I suspect it may not work on
6436 some platforms). The code was incorrect anyway, as it assumed
6437 that \$ evaluated to itself in that context. Reported by
6438 Alexandre Duret-Lutz.
6440 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6442 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6443 and _LT_AC_TAGCONFIG.
6445 2004-01-06 Paul Eggert <eggert@twinsun.com>
6447 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6448 example, and add more examples. Reported by Eric Sunshine.
6450 2004-01-05 Paul Eggert <eggert@twinsun.com>
6452 * doc/autoconf.texi (Limitations of Usual Tools):
6453 Remove warning against "rm -fr" introduced yesterday; it
6454 was a false alarm.
6456 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6457 autoscan, autoupdate, ifnames): Don't use chmod -w.
6458 * lib/Makefile.am (autom4te.cfg): Likewise.
6459 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6460 "chmod -w".
6462 2004-01-04 Paul Eggert <eggert@twinsun.com>
6463 Paolo Bonzini <bonzini@gnu.org>
6465 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6466 by doing lineno substitution only on lines containing "$LINENO".
6468 2004-01-04 Paul Eggert <eggert@twinsun.com>
6470 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6471 Use "rm -f" to remove conftest.sed, not plain "rm".
6472 Bug reported by David Relson in
6473 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6475 * Makefile.am (autom4te-update):
6476 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6477 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6478 * doc/autoconf.texi (Guidelines): Likewise.
6479 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
6480 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.
6481 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6482 * lib/autotest/general.m4 (AT_INIT): Likewise.
6483 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
6484 * tests/Makefile.am (clean-local): Likewise.
6485 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6486 srcdir): Likewise.
6487 * doc/autoconf.texi (Limitations of Usual Tools):
6488 Warn against "rm -fr".
6490 2004-01-03 Paul Eggert <eggert@twinsun.com>
6492 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6493 -c -o might not work. From a suggestion by Kevin Ryde.
6494 (C Compiler, Generating Sources, Limitations
6495 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6496 Don't put '-o' after non-options, as POSIX doesn't allow this.
6497 Mention that cc's name might be gcc or c89 or whatever.
6499 2004-01-04 Kevin Ryde <user42@zip.com.au>
6501 * doc/autoconf.texi: Add various further index entries.
6503 2003-12-29 Paul Eggert <eggert@twinsun.com>
6505 * bin/autoreconf.in (autoreconf_current_directory):
6506 Fix typo: mkdir without umask arg.
6508 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6510 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6511 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6512 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6513 explanation clearer.
6515 2003-12-24 Andreas Schwab <schwab@suse.de>
6517 * doc/autoconf.texi (Default Includes): Fix misspelling of
6518 AC_INCLUDES_DEFAULT.
6520 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6522 * configure.ac: Test if sh -n works.
6523 * configure: Regenerate.
6524 * tests/atlocal.in: Store the result here.
6525 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6526 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6527 of explicitly testing.
6528 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6529 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6530 * tests/tools.at (Syntax of the shell scripts): Simplify
6531 using AT_CHECK_SHELL_SYNTAX.

6533 AT_CHECK_PERL_SYNTAX.

6538 stderr to /dev/null.
6539 * bin/autoconf.in: Regenerate.
6540 * bin/wrapper.in: Regenerate.

6544 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6545 Extracted from AS_SHELL_SANITIZE.
6546 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6547 macros.
6548 (AS_SHELL_SANITIZE): Move reinvocation code from
6549 _AS_LINENO_WORKS, use it to find out if shell
6550 functions work.
6551 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6552 does not work.
6553 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6554 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

6565 (&sizes): New.
6566 Use them.

6568 them on the fly.
6570 2003-11-24 Akim Demaille <akim@epita.fr>
6572 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6605 the expanded body, consistently with other macros such as AC_USG.

6609 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes

6611 patch 3 reported by Eric Sunshine.
6613 2003-11-15 Kevin Ryde <user42@zip.com.au>
6615 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6616 than $target since the latter is not usual, add guidelines on when to
6617 use or not use the system type.
6619 2003-11-12 Derek Price <derek@ximbiot.com>
6621 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

6695 than `\n\n', so that `\n\n\n' is valid in warnings.
6696 Reported by Steve Huston.
6698 2003-10-28 Akim Demaille <akim@epita.fr>
6700 * Makefile.cfg (local_updates, executable-update): Tweak to be

6729 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_COMPILE_IFELSE):

6788 * bin/ifnames.in: Likewise.
6790 2003-10-09 Paul Eggert <eggert@twinsun.com>
6792 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
6793 Issue a more-informative diagnostic.
6794 Problems reported by Eric Sunshine.
6796 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6798 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6799 -mGLOB_options_string stuff for Intel ifc, which can cause
6800 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
6801 pattern-matching instead of grep.
6803 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6805 * doc/autoconf.texi: Document new FC Fortran macros.
6807 2003-10-08 Gary V. Vaughan <gary@gnu.org>
6809 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6810 that future autopoint/aclocal/automake/autoreconf will be able
6811 to trace to find where to install local m4 macros.
6812 * doc/autoconf.texi (Input): Document it.
6813 * NEWS: Updated.
6815 2003-10-06 Gary V. Vaughan <gary@gnu.org>
6817 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
6818 -lcrtbegin.o to list of ignored flags and fix underquoting of
6819 -lcrt[01].o.
6821 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6823 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6824 cache variable instead of $G77 to decide whether to include -O2,
6825 since $G77 is specific to Fortran 77.
6827 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6829 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6830 free" flag. Re-order flags tested into rough order of popularity.
6832 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6834 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6835 arguments so that it can be used with syntax identical to
6836 AC_PROG_F77, and so that we can more easily decide to
6837 remove/deprecate the DIALECT optional argument in the future if it
6838 proves troublesome.
6839 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6840 non-freeform-supporting compilers. Document freeform flags.
6842 2003-10-03 Akim Demaille <akim@epita.fr>
6844 * configure.ac: Look for emacs, not macs.
6845 Reported by Eric Sunshine.
6847 2003-10-03 Akim Demaille <akim@epita.fr>
6849 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6850 * bin/autoreconf.in (autoreconf_current_directory): Create the
6851 AUX_DIR if needed, for sake of automake --add-missing etc.
6852 Suggested by Alexandre Duret-Lutz.
6854 2003-10-03 Akim Demaille <akim@epita.fr>
6856 * configure.ac: Quotation and formatting changes.
6857 (EMACS): Don't set it if it is not recent enough to support
6858 autoconf-mode.el.
6859 From Eric Sunshine.
6861 2003-10-02 Akim Demaille <akim@epita.fr>
6863 * bin/ifnames.in (&scan_file): Skip C++ comments.

6873 Version 2.57f.
6875 2003-09-30 Paul Eggert <eggert@twinsun.com>
6877 * lib/Autom4te/XFile.pm: Use Errno.
6878 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6879 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6881 2003-09-30 Akim Demaille <akim@epita.fr>
6883 * config/announce-gen (&print_news_deltas): Extracted from...
6884 (&print_changelog_deltas): here.
6885 (&news_file): Rename as...
6886 (@news_file): this.
6888 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
6890 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
6891 have been created when invoking the compiler.
6892 * tests/fortran.at (GNU Fortran 77): Quote $G77.
6894 2003-09-29 Akim Demaille <akim@epita.fr>
6896 Version 2.57e.
6898 * config/mkinstalldirs: Upgrade.
6900 2003-09-28 Paul Eggert <eggert@twinsun.com>
6902 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
6903 Problem reported by Lars J. Aas in
6904 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6905 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6906 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6907 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6909 2003-09-26 Akim Demaille <akim@epita.fr>
6911 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6912 directory for AC_CONFIG_COMMANDS' first argument exists.
6913 This makes valid the invocation of _AC_SRCPATH that follows.
6914 Reported by Eric Sunshine.
6915 * doc/autoconf.texi (Configuration Commands): Adjust.
6917 2003-09-26 Akim Demaille <akim@epita.fr>
6919 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6920 Reported by Ralf Corsepius.
6922 2003-09-26 Akim Demaille <akim@epita.fr>
6924 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6925 arguments.
6926 Actually, use AU_ALIAS.
6927 From Bruno Haible.
6929 2003-09-26 Paul Eggert <eggert@twinsun.com>
6931 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6932 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6933 Problem reported by Eric Sunshine in:
6934 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
6936 2003-09-26 Akim Demaille <akim@epita.fr>
6938 The test suite are sometimes assigning timings incorrectly.
6939 Reported by Henk Krus.
6940 Diagnosed by Nicolas Joly.
6942 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6943 AT_help_all.
6944 Instead of making AT_help a sequence of assignments to grow
6945 $at_help_all, just make AT_help_all be the growing contents of
6946 $at_help_all, and make a single assignment in...
6947 (AT_INIT): here.
6948 (at_times_skip): Flip the meaning and rename as...
6949 (at_times_p): this.
6950 (AT_INIT): When summarizing the test that ran, remove
6951 $at_times_file after use, and check it is present before trying to
6952 use it.
6954 2003-09-25 Akim Demaille <akim@epita.fr>
6956 Version 2.57d.
6958 * bin/Makefile.am (edit): Handle '@configure_input@'.
6959 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6960 (ifnames): chmod -w.
6961 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6962 executables, not bin/ executables! Otherwise all the magic needed
6963 to find non installed files is turned off. This caused a failure
6964 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6965 as found in its environment (sent by tests/autoreconf): pointing
6966 to bin/autom4te that could not find its files.
6967 * tests/mktests.sh: Force the replacement of generated files, for
6968 the sake of "mv" program that are interactive when overwriting a
6969 -w file.
6970 * config/install-sh: Upgrade from CVS Automake.
6972 2003-09-23 Paul Eggert <eggert@twinsun.com>
6974 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6975 versus test -L issues.
6977 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6978 Paul Eggert <eggert@twinsun.com>
6980 Trivial change to support GCC's configuration procedure.
6981 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6982 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6983 about inconsistency if the preprocessor is set to give errors for
6984 any warning.
6985 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6987 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6989 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6990 and XFile.pm from Automake.
6991 * lib/Autom4te/XFile.pm: Update from Automake.
6993 2003-09-12 Akim Demaille <akim@epita.fr>
6995 Version 2.57c.
6997 2003-09-12 Akim Demaille <akim@epita.fr>
6999 * config/config.guess, config/config.sub, config/missing,
7000 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
7001 from masters.
7003 2003-09-12 Akim Demaille <akim@epita.fr>
7005 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7006 not asm/types.h.
7008 2003-09-11 Akim Demaille <akim@epita.fr>
7010 * doc/autoconf.texi (Header Portability): linux/random.h.
7011 From Peter Hendrickson.
7013 2003-09-10 Akim Demaille <akim@epita.fr>
7015 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7016 willing to edit the output files.
7018 2003-09-10 Akim Demaille <akim@epita.fr>
7020 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7021 and AC_FC_FREEFORM.
7022 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7023 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
7025 2003-09-09 Akim Demaille <akim@epita.fr>
7027 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.

7034 trailing files.
7036 2003-09-07 Paul Eggert <eggert@twinsun.com>
7038 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
7039 Improve the accuracy of the wording about obsolescence.
7040 From a suggestion by Ian Lance Taylor in
7041 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7043 2003-09-05 Paul Eggert <eggert@twinsun.com>
7045 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7046 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7048 2003-09-04 Akim Demaille <akim@epita.fr>
7050 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7051 AC_FUNC_WAIT3.
7053 2003-09-04 Akim Demaille <akim@epita.fr>
7055 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7056 (freeze): When exiting, use $exit_code.
7057 * lib/autoconf/fortran.m4: Comment changes.
7059 2003-09-04 Akim Demaille <akim@epita.fr>
7061 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7063 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7065 Add support for newer Fortran dialects. The F77 interface is
7066 unchanged, and continues to support Fortran 77. New FC macros
7067 correspond to all the old F77 macros, with output variables FC,
7068 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7069 available dialect, but older dialects can be specified. There are
7070 new macros AC_FC_SRCEXT to set the source extension, and
7071 AC_FC_FREEFORM to accept free-form source files.
7073 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7074 New macros.
7075 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
7076 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
7077 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
7078 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

7085 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
7086 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
7087 AC_FC_SRCEXT, AC_FC_FREEFORM):
7088 New macros.
7089 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
7090 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
7091 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7092 Rewrite in terms of the above.
7093 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7094 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
7095 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
7096 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
7098 2003-09-02 Paul Eggert <eggert@twinsun.com>
7100 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7101 Document problems with timestamp resolution that 'make', 'cp -p', and
7102 'touch -r' have.
7104 2003-08-27 Akim Demaille <akim@epita.fr>
7106 * tests/m4sugar.at (cross_warning): Make sure to enable the
7107 output, so that we can track spurious m4sugar output.
7108 * tests/local.at: Require 2.57.
7109 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7110 are defaulted by AT_CHECK anyway.
7111 Use AT_CHECK_AUTOM4TE.
7112 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7113 missing dnl.
7115 2003-08-27 Akim Demaille <akim@epita.fr>
7117 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7118 when -Wobsolete is set.
7119 Set it on by default.
7120 Suggested by Klee Dienes.
7122 2003-08-27 Akim Demaille <akim@epita.fr>
7124 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
7125 documentation.
7126 From Guido Draheim.
7128 2003-08-26 Akim Demaille <akim@epita.fr>
7130 * doc/autoconf.texi (Output): Make clear that one can run code
7131 after AC_OUTPUT.
7133 2003-08-25 Akim Demaille <akim@epita.fr>
7135 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
7136 CVS Bison.
7138 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
7140 * bin/autoreconf.in (parse_args): Do not pass --no-force to

7152 2003-08-22 Akim Demaille <akim@epita.fr>
7154 Version 2.57b.
7156 * Makefile.cfg (local-checks-to-skip): New.
7157 * Makefile.maint (local-check): Rename as...
7158 (local-checks-available): this.
7159 (local-check): New.
7161 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
7162 * configure.ac: Require Automake 1.7.6.
7164 2003-08-22 Akim Demaille <akim@epita.fr>
7166 Output stack traces in warnings.
7168 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7169 Replace the former...
7170 (m4_warn): Pass the call stack to _m4_warn.
7171 * bin/autom4te.in: Adjust to output the call stack.
7172 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7174 2003-08-22 Akim Demaille <akim@epita.fr>
7176 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7177 * bin/autom4te.in: Adjust.
7179 2003-08-21 Akim Demaille <akim@epita.fr>
7181 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7182 (&verbose): Remove.
7183 (&getopt): Adjust the note and verb channels, depending upon
7184 --verbose.
7185 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7186 * bin/autoupdate.in: Adjust.
7187 Use &verb, not &verbose.
7189 2003-08-21 Akim Demaille <akim@epita.fr>
7191 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7192 &parse_WARNINGS.
7193 ($help): Use Autom4te::ChannelDefs::usage.
7194 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7195 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7197 2003-08-21 Akim Demaille <akim@epita.fr>
7199 First stab at preserving warnings between calls to autom4te,
7200 including when the cache is used.
7202 There are still several issues: (i) there are too many runs of m4
7203 (one for include, one for warnings, and some more), (ii) warnings
7204 spreading on several lines are not handled gracefully, (iii) the
7205 code meant to have the call stack display for errors does not work
7206 (its handling should move from m4 to autom4te).
7208 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7209 Use them.
7210 (@preselect): Add m4_warn.
7211 ($exit_status): Remove, use $exit_code.
7212 ($help): Use Autom4te::ChannelDefs::usage.
7213 (&handle_m4): No longer define the m4_warnings.
7214 At each run, extract and report the warnings.
7215 Always cache the result, including if the exit status is on
7216 failure, since if nothing changes, we should result in the same
7217 failure, hence we can use the cache.
7218 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7219 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7220 Remove.
7221 (m4_warn): Redefine as a do-nothing: it is its invocation that
7222 matters, as warnings are now reported via traces.
7223 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7224 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7225 the latter reveals calls to the former.
7227 Adjust the tests.
7229 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7231 2003-08-21 Akim Demaille <akim@epita.fr>
7233 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7234 Use them.
7236 2003-08-21 Akim Demaille <akim@epita.fr>
7238 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7239 forward order.
7240 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7241 (&parse_warnings): Accept a list of warning requests.
7242 (&usage): Return a string, not a side effect.
7243 (cross): New warning category.
7245 2003-08-21 Akim Demaille <akim@epita.fr>
7247 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7248 (&require_configure_ac): Accept an optional directory argument.
7249 ($configure_ac): Remove.
7250 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7251 (&catfile): Remove.
7252 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7253 * bin/autoscan.in: Adjust.
7255 2003-08-20 Akim Demaille <akim@epita.fr>
7257 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7258 Reported by Alexandre Duret-Lutz.
7260 2003-08-20 Akim Demaille <akim@epita.fr>
7262 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7263 * bin/autom4te: Adjust.
7264 In particular, be Autoconf tools are really silent when properly
7265 working, bind the verbosity of the 'note' channel to $verbose.
7266 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7267 (&xsystem, &contents): Remove, since they are exported by...
7268 * lib/Autom4te/FileUtils.pm: this.
7269 More perldoc.
7270 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7271 * lib/Autom4te/FileUtils.pm: here.

7315 RUN-IF-PASS optional arguments.

7329 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7330 shorter column three. Add DESCRIPTION to log file content.
7332 2003-08-13 Derek Price <derek@ximbiot.com>
7334 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7335 output.
7337 2003-08-12 Derek Price <derek@ximbiot.com>
7339 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7340 (AT_CHECK_NOESCAPE): Move core functionality to...
7341 (_AT_CHECK): ...this new macro.
7343 2003-08-07 Derek Price <derek@ximbiot.com>
7345 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7346 (AT_CHECK_NOESCAPE): ...to this new macro.
7348 2003-07-31 Paul Eggert <eggert@twinsun.com>
7350 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7351 in Bash 2.01. Problem reported by Brian Gough in
7352 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7354 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7356 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7357 -lcrt1.o, for OS X. (trivial change)
7359 2003-07-07 Paul Eggert <eggert@twinsun.com>
7361 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7362 inside '#ifndef __cplusplus'. Problem reported by
7363 Bob Friesenhahn.
7365 2003-07-06 Bill Clarke <llib@computer.org>
7367 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7368 'long', not 'int', for benefit of Sun's recent C++ compilers
7369 (trivial change). See:
7370 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7371 (This really should be 'intptr_t', not 'long', but that would
7372 take more work.)
7374 2003-06-25 Akim Demaille <akim@epita.fr>
7376 * lib/Makefile.am (autom4te.cfg): Make it read only.
7377 Depend on Makefile since it contains substitutions.
7378 From Paolo Bonzini.
7379 * lib/autom4te.in (args): Add local.at? for Autotest args.
7380 This change was made on autom4te.cfg which is generated.
7381 Reported by Raja R. Harinath.
7383 2003-06-25 Akim Demaille <akim@epita.fr>
7385 * doc/autoconf.texi (Header Portability): sys/mount.h.
7386 From Gareth McCaughan.
7388 2003-06-23 Akim Demaille <akim@epita.fr>
7390 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7391 not all of them. This fixes 1. the fact that when testing
7392 Autoconf there are many many config.log, 2. the incorrect use of
7393 top_srcdir to find config.log.
7394 Don't mix the detailed output of failed test with the summary of
7395 failures. Rather, append detailed log afterwards.
7397 2003-06-23 Akim Demaille <akim@epita.fr>
7399 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7400 always run: output config.log on $at_group_log.
7402 2003-06-23 Akim Demaille <akim@epita.fr>
7404 * tests/torture.at (#define header templates): Don't use quotes in
7405 C++ comments as it puzzles Emacs' sh font-lock-mode.
7407 2003-06-23 Akim Demaille <akim@epita.fr>
7409 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7410 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7411 * tests/atspecific.m4: Rename as...
7412 * tests/local.at: This.
7413 * tests/suite.at: Move the globals into...
7414 * tests/local.at: here.
7415 * tests/Makefile.am: Adjust.
7416 * doc/autoconf.texi (testsuite Scripts): Adjust.
7418 2003-06-21 Kevin Ryde <user42@zip.com.au>
7420 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7421 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7422 ensuring we add -std1 for full-ANSI.
7424 * doc/autoconf.texi (hdrindex): New macro.
7425 Add index entries for portability of various standard header files.
7427 2003-06-20 Akim Demaille <akim@epita.fr>
7429 * configure.ac: Bump to 2.57b.
7431 2003-06-20 Akim Demaille <akim@epita.fr>
7433 Version 2.57a.
7435 2003-06-20 Akim Demaille <akim@epita.fr>
7437 * bin/autom4te.in: Don't rely on $HOME being defined.
7438 Reported by Marc Espie as PR/233.
7440 2003-06-20 Akim Demaille <akim@epita.fr>
7442 * lib/autotest/general.m4: Use at_times_file only if used.
7443 From Nicolas Joly.
7445 2003-06-20 Akim Demaille <akim@epita.fr>
7447 * config/config.guess, config/config.sub, config/elisp-comp,
7448 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7449 Update from masters.
7451 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7453 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7454 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7455 (TEST_SCRIPT): New diversion.
7456 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7457 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7458 (AT_INIT): Support for expected failures.
7460 2003-06-02 Akim Demaille <akim@epita.fr>
7462 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7463 changes.
7464 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7465 Autoconf nor Automake.
7466 (&contents): New, from Automake.
7467 PODify.
7469 2003-05-28 Paul Eggert <eggert@twinsun.com>
7471 * NEWS, doc/autoconf.texi (Particular Functions),
7472 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7473 is the inverse of localtime.
7475 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7477 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7478 (handle_exec_errors): New function. Work around $! being
7479 altered by WEXITSTATUS.
7480 (xqx, xsystem): Use handle_exec_errors.
7482 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7484 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7485 Do not call `_exit()', simply modify `$?'.
7486 (xsystem): Reset $! before running system, and check it afterward.
7487 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7488 63 for version mismatches.
7490 2003-05-23 Akim Demaille <akim@epita.fr>
7492 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7493 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7494 the middle of a line).
7495 * lib/m4sugar/m4sugar.m4: Likewise.
7496 Remove useless spaces in comments.
7498 2003-05-23 Akim Demaille <akim@epita.fr>
7500 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7501 exit 63, so that we (or Automake's "missing") can tell the
7502 difference with a plain failure.
7503 * doc/autoconf.texi (Notices): Adjust.
7505 2003-05-23 Akim Demaille <akim@epita.fr>
7507 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7508 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7509 White spaces cleanup.
7511 2003-05-22 Jim Meyering <jim@meyering.net>
7512 Paul Eggert <eggert@twinsun.com>
7514 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7515 Remove `#include <stdlib.h>' from the list; we should never
7516 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7517 resulting namespace pollution would cause other tests to fail.
7518 Configure scripts run with some older versions of g++ and HP's
7519 aCC would fail due to such an #include. Problems reported by
7520 Matthew Mueller in <http://bugs.debian.org/120704> and by
7521 Keith Bostic in
7522 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7523 In the test, use the test declaration before including <stdlib.h>,
7524 as that's closer to how it'll be used.
7526 2003-05-23 Akim Demaille <akim@epita.fr>
7528 * doc/autoconf.texi (Header Portability): ucred.h.
7529 From Ian Redfern.
7531 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7533 Overhaul Autotest's logging: generate separate log files
7534 in testsuite.dir/NNN/testsuite.log, and append them to
7535 testsuite.log instead of re-running the test verbosely.
7537 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7538 file descriptor, write 0 to at_status_file instead of setting
7539 at_status=0, initialize some new variables (at_status_file,
7540 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7541 to rerun the tests, instead append the at_group_log to the
7542 at_suite_log when a test fails.
7543 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7544 with the AS_MESSAGE_LOG_FD redirected to stdout.
7545 (AT_CLEANUP): save the output status in $at_status_file
7546 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7547 its original place.
7548 (AT_CHECK): since tests are run with a redirected stdout,
7549 and used to be re-run in verbose mode, turn some $at_verbose
7550 into echo, and don't redirect the output of testing stdout
7551 and stderr.
7553 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7554 the name of the debugging directory and information about
7555 its contents.
7557 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7559 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7560 parameter.
7562 2003-05-22 Akim Demaille <akim@epita.fr>
7564 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
7565 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
7566 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

7582 Whitespace clean up.
7583 Suggested by Jim Meyering.
7585 2003-05-22 Akim Demaille <akim@epita.fr>
7587 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
7588 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
7589 Reported by Jim Meyering.
7591 2003-05-22 Akim Demaille <akim@epita.fr>
7593 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
7594 Add AC_HELP_STRING to the obsolete macros section.
7595 Typos.
7596 Use '@.' for sentences that ended in a capital letter.
7597 From Art Haas.

7608 it to eval.
7610 2003-05-21 Akim Demaille <akim@epita.fr>
7612 * bin/autoupdate.in ($m4): Fix quotation.
7613 Reported by Martin Mokrejs.
7615 2003-05-19 Paul Eggert <eggert@twinsun.com>
7617 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

7624 AC_CHECK_HEADERS_NEW): New tests.
7626 2003-05-17 Akim Demaille <akim@epita.fr>
7628 * lib/autoconf/functions.m4: Use the default includes so that
7629 memcmp be declared before being tested.
7630 Reported by Sander Niemeijer.
7631 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7632 * doc/autoconf.texi (Default Includes): Document
7633 AC_INCLUDES_DEFAULT.
7635 2003-05-17 Akim Demaille <akim@epita.fr>
7637 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7638 * doc/autoconf.texi (Obsolete Macros): Adjust.
7639 Reported by Werner LEMBERG and Debian Bug 190886.
7641 2003-05-16 Akim Demaille <akim@epita.fr>
7643 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
7644 user name space clashes.
7645 Reported by Bruno Haible.
7647 2003-05-16 Akim Demaille <akim@epita.fr>
7649 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7650 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
7651 them uniform, and more robust to Perl special characters.
7652 Reported by Martin Mokrejs.
7654 2003-05-14 Akim Demaille <akim@epita.fr>
7656 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
7658 2003-05-14 Akim Demaille <akim@epita.fr>
7660 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

7665 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
7666 message.
7667 From Matthias Andree.
7669 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
7671 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
7672 and truncate.
7674 2003-05-06 Akim Demaille <akim@epita.fr>
7676 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7677 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7678 by aclocal.m4 is changed it might require the importing of another
7679 m4 extension file, i.e., aclocal must be run.
7681 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7682 (&parse_args): Use --force with aclocal if required and supported.
7683 (&autoreconf_current_directory): Use &run_aclocal.
7685 2003-05-06 Akim Demaille <akim@epita.fr>
7687 Lock autom4te's cache.
7689 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7690 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7691 argument instead of a file name, so that the request file remains
7692 open during the whole autom4te run.
7693 ($icache_file): New.
7694 (&freeze): Lock the $icache_file.
7696 2003-04-29 Derek Price <derek@ximbiot.com>
7698 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7699 seperator with m4_append_uniq(). It doesn't work.
7700 (AT_CLEANUP): Add `;' to end of at_help_all.
7701 (AT_INIT): Allow --keywords to be specified more than once. When
7702 grepping $at_help_all for keywords, use the field and keyword
7703 seperators to ensure a complete keyword match. Alter at_prev handling
7704 to support the new --keywords behavior.
7706 2003-04-27 Karl Berry <karl@freefriends.org>
7708 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7709 align better with others. I also made some of the individual
7710 entries on one line, for brevity and to make it easier for me to
7711 sort my dir-example file in the Texinfo distribution :).
7713 2003-04-12 Jim Meyering <jim@meyering.net>
7715 * NEWS: Mention the new macro.
7716 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

7733 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,

7778 header causes problems.
7780 2003-03-28 Akim Demaille <akim@epita.fr>
7782 * tests/torture.at (Configuring subdirectories): Require aclocal
7783 1.4, otherwise the test fails, as it does support configure.ac.

7806 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
7807 obsolete AC_HELP_STRING.
7808 (AC_HELP_STRING): AU_DEFUN to...
7809 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
7810 * tests/m4sh.at (AS_HELP_STRING): New test.
7812 * tests/acgeneral.at: Regenerated.
7814 2003-03-26 Derek Price <derek@ximbiot.com>
7816 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7817 sense. Verbosify the diversion definitions comment.

7857 (Automake): Automake 1.5+ no longer requires special tools to be
7858 present on the developer's host.
7860 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7862 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
7863 to a shell that can handle redirection or quoting correctly.

7865 Use of $^O suggested by Tim van Holder.
7866 * bin/autom4te.in (BEGIN): Likewise.
7867 * bin/autoreconf.in (BEGIN): Likewise.
7868 * bin/autoscan.in (BEGIN): Likewise.
7869 * bin/autoupdate.in (BEGIN): Likewise.

7872 * bin/ifnames.in: Add final newline to help and version messages.
7874 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7875 to cope with DOS-style absolute paths, when constructing
7876 ${ac_make}.
7878 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7879 When constructing paths with IFS=:, quote the path. If we're
7880 constructing a DOS-style absolute path, we don't want to split it
7881 on the colon.
7883 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7884 in description.
7886 2003-02-25 Pavel Roskin <proski@gnu.org>

7898 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7899 to fix a mismatch between example and discussion.
7901 2003-02-24 Kevin Ryde <user42@zip.com.au>
7903 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7904 format starting with "-".
7906 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7908 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7909 is not portable inside Makefile.
7911 2003-02-20 Akim Demaille <akim@epita.fr>
7913 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7914 compiler says yeah, but preproc says nope, compiler is right.
7915 Conversely, prompt the reader to send a bug report to the
7916 maintainers of the package, not of Autoconf.
7918 2003-02-20 Klee Dienes <kdienes@apple.com>
7920 * bin/autoreconf.in (autoreconf_current_directory): Properly
7921 handle an empty aclocal.m4.

7926 $ac_prefix_program.
7927 From Larry Jones.
7929 2002-12-23 Paul Eggert <eggert@twinsun.com>
7931 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7932 innocuous variant befor including <limits.h> or <assert.h>. This
7933 works around a bug reported by Albert Chin: HP-UX 11i
7934 (and earlier versions) have a <limits.h> that declares
7935 gettimeofday and many other functions.
7937 2002-12-03 Paul Eggert <eggert@twinsun.com>
7939 Version 2.57.
7941 * NEWS, configure.ac: Update version.
7943 * doc/fdl.texi: Upgrade to FDL version 1.2.
7945 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7946 nontrivially in main's body, so that f's external declaration is
7947 not optimized away in AIX. This should fix the bug reported by
7948 Martin Frydl in
7949 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7951 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7952 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7953 defined, to support freestanding compilers. This should fix the
7954 bug reported by Momchil Velkov in
7955 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7957 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7958 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7963 * Makefile.maint (www-gnu): New macro.
7964 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7965 the location has moved.
7967 2002-12-02 Martin Frydl <martin@systinet.com>
7969 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7970 \(.*\) match is too long and there is something more to be checked.
7971 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7973 2002-11-15 Akim Demaille <akim@epita.fr>

7979 * config/move-if-change: Indenting changes.
7980 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7981 * configure.ac (AM_INIT_AUTOMAKE): here.
7982 Require 1.7.1.
7984 2002-11-14 Akim Demaille <akim@epita.fr>
7986 Version 2.55.
7988 * config/config.guess, config/config.sub, config/install-sh:
7989 Update from masters.
7991 2002-11-14 Akim Demaille <akim@epita.fr>
7993 * Makefile.maint: Sync with Bison, i.e.:
7994 (po-check): Scan .l and .y files instead of the
7995 .c and the .h files that they generate. This fixes the bug
7996 reported by Tim Van Holder in:
7997 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7998 Look for N_ as well as for _. Try to avoid matching #define for
7999 N_ and _.
8000 From Paul Eggert.
8002 2002-11-14 Akim Demaille <akim@epita.fr>
8004 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8005 From Paul Eggert and Albert Chin-A-Young.
8007 2002-11-14 Akim Demaille <akim@epita.fr>
8009 * doc/autoconf.texi (C Compiler): Solitary backslashes.
8010 From Paul Eggert and Albert Chin-A-Young.
8012 2002-11-14 Kevin Ryde <user42@zip.com.au>
8014 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8015 than assigning in main, to avoid HP cc +O3 optimizing it away.
8017 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8019 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8020 option. Process --recheck after parsing all options. Pass -q
8021 option to configure on --recheck.
8022 (AC_OUTPUT): Pass -q from configure to config.status.
8023 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8024 arguments to record.
8025 * doc/autoconf.texi (config.status Invocation): Document
8026 config.status -q option.
8028 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8031 Makefile.in if Makefile.am exists.
8032 (output): Strip `.am' from Makefiles. Don't
8033 output AC_CONFIG_FILES if no Makefiles were found.
8035 2002-11-07 Akim Demaille <akim@epita.fr>

8042 2002-11-06 Akim Demaille <akim@epita.fr>
8044 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
8045 declaration in extern "C" too.

8050 * tests/torture.at (Configuring subdirectories): Don't use grep
8051 -w.
8052 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
8053 Reported by Ezra Peisach.
8055 2002-11-05 Akim Demaille <akim@epita.fr>
8057 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8058 Remove.
8059 We _have_ to stop using the old compatibility scheme that tried to
8060 avoid useless backslashes because Libtool 1.4.3 contains a
8061 AC_DEFINE([error_t], [int],
8062 [Define to a type to use for \`error_t' if it is not
8063 otherwise available.])
8064 We _have_ to quote the single quote and backslashes with \. The
8065 old compatibility scheme saw that ` was backslashed, and therefore
8066 did not quote the single quote. Hence before this patch, Autoconf
8067 was not compatible with Libtool.
8069 2002-11-04 Paul Eggert <eggert@twinsun.com>
8071 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8076 2002-11-04 Akim Demaille <akim@epita.fr>
8078 Version 2.54c.
8080 * Makefile.maint (update, cvs-update, po-update, do-po-update):
8081 New.
8082 * config/texinfo.tex: Update.
8084 2002-11-03 Akim Demaille <akim@epita.fr>
8086 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
8087 from...
8088 (&autoreconf): here.
8089 ($help, $make, &parse_args, &autoreconf_current_directory):
8090 Support -m/--make.
8091 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8093 2002-10-31 Bruno Haible <bruno@clisp.org>

8107 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
8109 2002-10-31 Akim Demaille <akim@epita.fr>
8111 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8112 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8113 Make variable, not a shell variable.
8114 Suggested by Bruno Haible.
8116 2002-10-31 Akim Demaille <akim@epita.fr>
8118 * bin/autom4te.in (load_configuration): Reject #args out of any
8119 language.
8121 2002-10-31 Akim Demaille <akim@epita.fr>
8123 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
8124 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

8126 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
8127 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

8129 inline it.

8135 Suggested by Tim van Holder.
8137 2002-10-29 Paul Eggert <eggert@twinsun.com>
8139 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8140 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8141 Problem reported by Bruno Haible.
8143 2002-10-29 Akim Demaille <akim@epita.fr>
8145 * doc/autoconf.texi (Header Templates): Put also in words what the
8146 pictures says to assist free style readers.
8147 (Customizing autom4te): s/--cache=/--cache /.
8149 2002-10-29 Akim Demaille <akim@epita.fr>
8151 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8152 sys/wait.h.
8153 sparc_address_test returns void.
8154 Use it with an argument, as prototyped.
8155 From Bruno Haible.
8157 2002-10-29 Akim Demaille <akim@epita.fr>
8159 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

8172 * doc/autoconf.texi (Invoking autom4te): Rename as...
8173 (autom4te Invocation): this, for consistency with the other nodes.

8399 2002-10-22 Akim Demaille <akim@epita.fr>
8401 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8404 Quote for Perl '' strings, not "".
8405 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8406 strings.
8408 2002-10-22 Akim Demaille <akim@epita.fr>
8410 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8457 longer required can still cause errors.
8458 Reported by Alexandre Duret-Lutz.
8460 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8461 to frozen files in @ARGV, as @ARGV must remain being a list of

8463 (&files_to_options): New function.
8464 (&freeze): Use &error.
8465 (&up_to_date): If a file that was included according to the cache
8466 is no longer there, then the output is out dated.

8468 --force is given.
8469 * tests/tools.at (autom4te cache): New.

8478 that error messages can be easily located, and use GNU Make
8479 format, so that Emacs' compile mode understands us.
8480 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8481 if some file was changed instead of `print'.
8482 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8516 file name to enable parallel executions.
8517 From Sam Varshavchik.
8519 2002-10-08 Akim Demaille <akim@epita.fr>
8521 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8522 aclocal invocation, as Gettext macros might not be visible to
8523 aclocal.
8524 Instead of blindly running autopoint, scan configure.ac (not the
8525 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8526 Reported by Paul D. Smith.
8528 2002-10-08 Paul Eggert <eggert@twinsun.com>
8530 Work around problems found when POSIXLY_CORRECT=1 is set.
8531 None of this seems to have anything to do with POSIX, really,
8532 but it's how Perl getopt works.
8533 * bin/autom4te.in (parse_args): Configure GetOpt with
8534 "permute", too.
8535 * doc/autoconf.texi (Invoking autom4te):

8558 * tests/torture.at (Configuring subdirectories): Be robust to
8559 users who use config.site to require for a cache: in this case,
8560 the two last configure runs, using two different sets of
8561 arguments, trigger a legitimate error.
8563 2002-09-28 Akim Demaille <akim@epita.fr>

8580 * lib/autoconf/types.m4: here, using AN_ macros.
8581 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8582 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8583 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

8598 tests/autom4te itself.
8599 * lib/autoscan/Makefile.am: Include freeze.mk.
8600 (autoscan.list): New target --this file is no longer a source.
8601 (autoscan.pre): New file.

8625 * bin/autoscan.in (&init_tables): Adjust.
8627 2002-09-28 Akim Demaille <akim@epita.fr>
8629 From now on, autoscan files must always map a macro name to a

8632 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8633 all.
8634 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8635 explicit.
8637 2002-09-28 Akim Demaille <akim@epita.fr>
8639 * bin/autoscan.in (%c_keywords): Remove.

8673 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8675 2002-09-26 Akim Demaille <akim@epita.fr>
8677 Single suffix rules and seperated dependencies are not portable.

8727 2002-09-13 Akim Demaille <akim@epita.fr>

8744 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8746 * doc/autoconf.texi: Review grammar and punctuation.
8748 2002-09-11 Paul Eggert <eggert@twinsun.com>
8750 * doc/autoconf.texi: Fix minor formatting, spelling, and
8751 grammatical typos.
8752 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8753 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8754 is obsolescent.
8756 2002-09-11 Akim Demaille <akim@epita.fr>
8758 * doc/autoconf.texi (Questions): Rename as...
8759 (FAQ): this.
8760 (Defining Directories): New.
8762 2002-09-09 Akim Demaille <akim@epita.fr>
8764 * doc/autoconf.texi (Making testsuite Scripts): Update.
8765 Suggested by Nishio Futoshi.
8767 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8769 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8770 plain `@' is wanted.
8772 2002-09-09 Akim Demaille <akim@epita.fr>
8774 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8775 `duplicates', since the algorithm was too naive and could keep
8776 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8777 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8778 Reported by Ralf Corsepius.
8779 * tests/torture.at (Configuring subdirectories): Exercise these
8780 cases.
8782 2002-09-09 Akim Demaille <akim@epita.fr>
8784 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8785 looking for a replacement file.
8786 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8787 directory is relative.
8788 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8789 directory definition.
8790 Reported by Andreas Schwab and Jim Meyering.
8792 2002-09-06 Akim Demaille <akim@epita.fr>
8794 * doc/autoconf.texi (Setting Output Variables): Clarify what
8795 precious variables are.
8796 Suggested by Pontus Skoeld.
8798 2002-09-05 Akim Demaille <akim@epita.fr>
8800 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8801 (ifnames, autoscan, autom4te): Since we don't only depend on
8802 configure.ac variables (such as VERSION etc.), but also on prefix
8803 and so forth, depend on Makefile, not configure.ac.
8804 Reported by Alexandre Duret-Lutz.
8805 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8807 2002-09-05 Kevin Ryde <user42@zip.com.au>
8809 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8810 doesn't seem to be confined to ia64, just say "some versions".
8812 2002-09-04 Akim Demaille <akim@epita.fr>
8814 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8815 Automake 1.6c.
8816 * Makefile.am (maintainer-clean-local): Remove.
8817 (MAINTAINERCLEANFILES): Remove COPYING.
8819 2002-09-03 Paul Eggert <eggert@twinsun.com>
8821 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8822 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8823 Brinkmann.
8825 2002-09-03 Akim Demaille <akim@epita.fr>
8827 * configure.ac: Bump to 2.53d.
8828 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8829 as of today, on Automake's team suggestion.
8831 2002-09-03 Akim Demaille <akim@epita.fr>
8833 Version 2.53c.
8835 2002-09-02 Akim Demaille <akim@epita.fr>
8837 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8838 SITE_MACRO_DIR.
8839 * configure.ac: Disable SITE_MACRO_DIR.
8841 2002-09-02 Jim Meyering <meyering@lucent.com>
8843 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8844 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8845 Also, tweak grammar: s/make sure to/be sure to/.
8847 2002-09-02 Paul Eggert <eggert@twinsun.com>
8849 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8850 directory names are generally preferable to physical names.
8852 2002-09-02 Akim Demaille <akim@epita.fr>
8854 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8855 Reported by Raja R. Harinath.
8856 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8857 * bin/autoupdate.in: Use error instead of die.
8859 2002-09-01 Paul Eggert <eggert@twinsun.com>
8861 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8862 ordinary shell concatenation rather than echo+tr+sed command that
8863 runs afoul of a long-line-related sed bug in Solaris 8.
8865 * bin/autoheader.in (parse_args): --warning -> --warnings.
8867 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8868 stdout, as traditional "ls" does.
8869 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8870 _AC_COMPILER_EXEEXT_O): Likewise.
8871 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8873 * bin/autoconf.as: Add --prepend-include option. This patch was
8874 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8875 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8877 * bin/autoconf.in, configure: Regenerate.
8879 * doc/autoconf.texi (Special Shell Variables): Mention
8880 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8882 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8883 MAILPATH and set PS1, PS2, PS4 to default values, to work
8884 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8885 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8886 the Autoconf documentation specifies; fall back to "unset" only if
8887 this fails. Use a shell for-loop for this rather than an m4 loop,
8888 to shorten the output script.
8890 2002-08-30 Paul Eggert <eggert@twinsun.com>
8892 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8893 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8894 for the CDPATH problem. Document PWD.
8895 (Limitations of Builtins): Document the problem that "cd $foo" and
8896 "ls $foo" may refer to different directories in shells conforming
8897 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8898 example, since the old example is now out of date.
8900 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8901 FOO" and "ls FOO" talk about different directories; this catches
8902 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8903 spaghetti.
8905 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8906 of rolling our own unset.
8907 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8908 in practice we needn't worry about CDPATH if unset doesn't work.
8910 * Makefile.in, aclocal.m4, bin/Makefile.in,
8911 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8912 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8913 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8914 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8915 tests/Makefile.in: Regenerate with Automake 1.6.3.
8917 * config/config.guess, config/config.sub, config/mkinstalldirs:
8918 Update.
8920 * configure: Regenerate with self.
8922 2002-08-30 Kevin Ryde <user42@zip.com.au>
8924 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8925 default output.
8927 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8929 * bin/autom4te.in (Request::load): Correctly test for "do" read
8930 failure.
8932 2002-08-29 Akim Demaille <akim@epita.fr>
8934 * lib/Autom4te/General.pm (&xqx): New.
8935 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8936 hand, which is not portable.
8937 (&error): New.
8938 * bin/autom4te.in: Use them.
8939 Use &error instead of die.
8940 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8941 Adjust.
8943 2002-08-17 Paul Eggert <eggert@twinsun.com>
8945 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8946 default list of compilers to try, since it was long ago superseded
8947 by the ksh fc builtin. Suggested by Steven G. Johnson.
8949 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8951 * doc/autoconf.texi (Invoking autom4te): End the option table,
8952 fixing a bug introduced by the previous patch.
8953 (Limitations of Make): Add a 'target lookup' subentry in the
8954 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8956 2002-07-29 Mark D. Roth <roth@feep.net>
8958 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8959 options and use $AUTOM4TE_PATH.
8960 * doc/autoconf.texi: Remove documentation of autom4te
8961 --include-envvar and --site-macro-subdir options and document
8962 use of $AUTOM4TE_PATH.
8963 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8964 arguments from each language section.
8966 2002-07-29 Paul Eggert <eggert@twinsun.com>
8968 * doc/install.texi: Include copyright symbol in copyright notice.
8970 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8971 Replace with:
8972 (AM_MAKEINFOFLAGS): New macro.
8973 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8974 * Makefile.am (INSTALL): Use the new macros.
8975 Use -o rather than --output, since "missing" does not grok --output.
8977 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8979 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8980 comments do not always work. Never trust the exit status of
8981 `make -k'.
8983 2002-07-24 Kevin Ryde <user42@zip.com.au>
8985 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8986 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8988 2002-07-23 Paul Eggert <eggert@twinsun.com>
8990 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8991 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8992 apparently treats PATH="nonexistent" as if it contained ".".
8993 Bug reported by Stefan `Sec' Zehl.
8995 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8997 * doc/autoconf.texi (Limitations of Make): Mention the special
8998 handling of the obj/ directory by BSD make.

9014 2002-07-18 Akim Demaille <akim@epita.fr>
9016 Version 2.53b.
9018 2002-07-18 Akim Demaille <akim@epita.fr>
9020 * config/config.guess, config/config.sub: Update.
9022 2002-07-18 Akim Demaille <akim@epita.fr>

9032 Alexandre Duret-Lutz <duret_g@epita.fr>
9034 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

9044 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
9045 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the

9050 * lib/Autom4te/General.pm (find_file): Browse the directories in

9146 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9147 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9148 on Solaris 2.5.1.
9150 2002-06-11 Andreas Schwab <schwab@suse.de>
9152 * doc/autoconf.texi: Add more dir entries.
9154 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9156 * bin/autom4te.in ($cache): Don't define using `$me', the name
9157 of the cache should not depend on the name under which autom4te
9158 was installed.
9160 2002-06-07 Akim Demaille <akim@epita.fr>
9162 * tests/tools.at (autoconf: forbidden tokens, basic)

9234 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
9235 * doc/autoconf.texi (Particular Programs): Document them.
9236 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
9237 * NEWS: Likewise.
9239 2002-05-27 Paul Eggert <eggert@twinsun.com>
9241 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
9242 * NEWS, doc/autoconf.texi (Particular Types): Document it.
9243 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
9244 instead of AC_MBSTATE_T, which never existed.
9246 2002-05-23 Akim Demaille <akim@epita.fr>
9248 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
9249 version of Autoconf that is discussed.
9251 2002-05-22 Paul Eggert <eggert@twinsun.com>
9253 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9254 from the default list of compilers to try. Suggested by
9255 Kate Hedstrom.
9256 * NEWS: Document the above.
9257 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9259 2002-05-17 Paul Eggert <eggert@twinsun.com>
9261 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9262 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9263 This improves on an earlier suggestion by H. Peter Anvin.
9265 2002-05-16 Paul Eggert <eggert@twinsun.com>
9267 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9268 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9269 Both macros now accept an optional source-dir arg.
9270 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9272 * NEWS: Document this.
9273 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9275 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9276 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9277 not for GNU extensions; this undoes part of the 2000-11-03 change,
9278 reverting to 2.13-compatible behavior.
9279 Add new optional argument DIR.
9280 (AC_FUNC_FNMATCH_GNU): New macro.
9282 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9284 2002-05-08 Paul Eggert <eggert@twinsun.com>
9286 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9287 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9288 and it causes a 'test' syntax error if it fails.
9289 Bug reported by Stephen Gildea.
9291 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9292 If prototypes are supported, use them to check this at compile-time,
9293 instead of trying to check it at run-time. If we must do a run-time
9294 check, assume that setvbuf is standard when cross-compiling, as
9295 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9296 Bug reported by Paul D. Smith.
9298 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9299 argument specifying location of getloadavg.c. This removes a
9300 FIXME. This idea was taken from Jim Meyering's implementation in
9301 textutils.
9302 * doc/autoconf.texi (Particular Functions): Document this.
9303 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9304 that's what the code does; this fixes a bug reported by
9305 Paul D. Smith.
9307 2002-05-03 Akim Demaille <akim@epita.fr>
9309 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9310 autopoint instead of gettextize.
9311 ($uses_alocal): Rename as...
9312 ($uses_aclocal): this.
9313 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9314 Suggested by Bruno Haible.
9316 2002-05-03 Akim Demaille <akim@epita.fr>
9318 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9320 2002-04-29 Paul Eggert <eggert@twinsun.com>
9322 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9323 files to be 1 second older; just set them to be the same time.
9324 Also, sleep 1 second after the first aclocal, to work around
9325 problems with sub-second time stamps on the input files.
9327 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9329 * doc/autoconf.texi: Mention "set -e -x" lossage
9330 under node "Limitations of Builtins".
9332 2002-04-29 Akim Demaille <akim@epita.fr>
9334 * doc/install.texi: Better wording for setting variables when
9335 running configure.
9336 From Christian Cornelssen.
9338 2002-04-29 Akim Demaille <akim@epita.fr>
9340 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9341 of lack of $LINENO support, then the test will compare the $LINENO
9342 in testsuite vs. the lineno in the test file. This is wrong, of
9343 course.
9344 Be sure to protect it.
9345 Reported by Patrick Welche.
9347 2002-04-25 Akim Demaille <akim@epita.fr>
9349 * doc/autoconf.texi (Obsolete Macros): Typo.
9350 Reported by Vladimir Volovich.
9352 2002-04-25 Akim Demaille <akim@epita.fr>
9354 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9355 than some of the input files, hence, on the second run of aclocal,
9356 if some of its input are younger, make them older.
9357 Suggested by Paul Eggert.
9359 2002-04-25 Akim Demaille <akim@epita.fr>
9361 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9362 Thanks to Paul Eggert.
9364 2002-04-25 Akim Demaille <akim@epita.fr>
9366 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9367 and ac_subst_vars be sh variables containing the list of
9368 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9369 DEFAULT diversion.
9370 (_AC_INIT_PREPARE): Use them to log them.
9371 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9372 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9373 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9374 _AC_SUBST_FILES and _AC_SUBST_VARS.
9375 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9377 2002-04-24 Akim Demaille <akim@epita.fr>
9379 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9380 autoheader, so that automake does not complain about a missing
9381 config.h.in that was to be created.
9383 2002-04-23 Akim Demaille <akim@epita.fr>
9385 * bin/autoheader.in (parse_args): --warning takes an argument.
9386 Fixes PR/220.
9388 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9390 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
9391 and bb.out when cleaning up.
9393 2002-04-22 Akim Demaille <akim@epita.fr>
9395 Version 2.53a.
9397 2002-04-22 Akim Demaille <akim@epita.fr>
9399 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
9401 2002-04-22 Akim Demaille <akim@epita.fr>
9403 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9404 comma.
9405 Reported by Gregory Giannoni.
9407 2002-04-22 Akim Demaille <akim@epita.fr>
9409 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9410 Fixes false failures on Darwin.

9416 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9435 Minor spelling and grammar fixes.
9437 * doc/autoconf.texi: Follow the outline suggested in the GNU
9438 Sample Texts sections of the Texinfo 4.2 manual. Most
9439 importantly, this makes sure that the copyright notices appear in
9440 all output formats. You probably need Texinfo 4.2 to generate
9441 the manual now.
9443 Fix some bugs when using "$@" when there might be zero positional
9444 arguments in cases where this matters.

9464 * tests/c.at: We can't have zero arguments, so remove workaround
9465 that is not portable to Zsh.
9467 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9469 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9470 from aclocal.m4 too.
9472 2002-04-12 Akim Demaille <akim@epita.fr>
9474 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9476 2002-04-10 Akim Demaille <akim@epita.fr>
9478 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9479 workaround for ${1+"$@"}.
9480 * doc/autoconf.texi (Shell Substitutions): Explain it.
9481 From Oliver Kiddle and Peter Stephenson.
9483 Have M4sh perform minimal shell sanitizing.
9485 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9486 part into...
9487 (_AS_PREPARE): this new macro.
9488 (AS_PREPARE): New.
9489 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9490 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9492 Adjust Autoconf and Autotest.
9494 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9495 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9496 * lib/autotest/general.m4 (AT_INIT): Likewise.
9497 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9498 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9499 AS_SHELL_SANITIZE.
9501 Use this M4sh to generate Autoconf's shell scripts.
9503 * tests/wrapsh.as: New, precursor of wrapsh.in.
9504 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9505 on Autotest and M4sh.
9506 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9507 (wrapsh.in): New target.
9508 * bin/autoconf.as: New, precursor of autoconf.in.
9509 (autoconf.in): New target.

9514 with indented comments in rules.
9516 2002-04-09 Andreas Schwab <schwab@suse.de>
9518 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9519 ac_top_builddir when setting ac_abs_top_builddir.
9521 2002-04-06 Kevin Ryde <user42@zip.com.au>
9523 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9524 (Portable Shell): Cross reference to Systemology.
9526 2002-04-05 Akim Demaille <akim@epita.fr>
9528 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9529 directories when descending in a SUBDIRS.
9530 Reported by Ezra Peisach.
9532 2002-04-04 Andreas Schwab <schwab@suse.de>
9534 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9535 contains no literal separators.
9537 2002-04-03 Akim Demaille <akim@epita.fr>
9539 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9540 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9541 Use dnl, not the KILL diversion.
9542 Extracted from...
9543 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9544 (AC_CONFIG_LINKS): here.
9545 Adjust.
9546 Don't use the KILL diversion, as it kills spurious output, which
9547 results in failures being hidden.
9548 Use m4_defn where appropriate.
9549 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9550 after the second argument.
9551 Use m4_defn.
9552 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9553 syntax, as it is provided by M4sugar.
9554 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9556 2002-04-03 Andreas Schwab <schwab@suse.de>
9558 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

9562 aclocal.
9564 2002-04-03 Akim Demaille <akim@epita.fr>

9569 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9570 (_AC_COMPILER_OBJEXT): Use them.
9571 Fixes Debian #138666.
9573 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9575 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9577 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9578 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9579 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9580 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9581 (AC_C_CONST): Same.

9591 _AS_MKDIR_P_PREPARE.
9593 2002-03-28 Kevin Ryde <user42@zip.com.au>
9595 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9596 to avoid versions of HP C which don't allow that.
9598 2002-03-27 Paul Eggert <eggert@twinsun.com>
9600 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9601 (AS_SHELL_SANITIZE): Invoke it.
9602 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

9612 2002-03-25 Paul Eggert <eggert@twinsun.com>
9614 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9615 as POSIX requires, as it doesn't work with Zsh.
9616 * doc/autoconf.texi (Assignments): Document the problem.
9618 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9620 * doc/autoconf.texi (Limitations of Make): Mention more issue
9621 about VPATH, overriding of macros in sub-makes, and handling of
9622 SHELL.
9624 2002-03-21 Paul Eggert <eggert@twinsun.com>
9626 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9627 problem with here-document buffer boundaries.
9629 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9630 when reinvoking the shell, to work around problems with installers
9631 who put strange things like "cd" commands in their environments.
9633 2002-03-19 Akim Demaille <akim@epita.fr>
9635 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9636 From Aaron Ucko.
9638 2002-03-19 Akim Demaille <akim@epita.fr>

9647 From Nishio Futoshi.
9649 2002-03-19 Akim Demaille <akim@epita.fr>
9651 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9653 2002-03-18 Paul Eggert <eggert@twinsun.com>
9655 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9656 (Limitations of Usual Tools): Add mkdir section.
9658 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9659 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9660 back on AS_DIRNAME to compute prefixes otherwise; this is
9661 roughly what mkinstalldirs does. That way, we need not have
9662 our own filename disassembler. The old disassembler did not
9663 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9665 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9666 Create at_test_all by a series of assignments,
9667 not by a single assignment of a long string. The latter causes ksh
9668 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9669 presumably because of a buffer overrun.
9671 2002-03-14 Paul Eggert <eggert@twinsun.com>
9673 * lib/autotest/general.m4 (at_times_skip):
9674 Renamed from at_times. Now a boolean.
9675 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9676 says 'times: not found'.
9678 2002-03-14 Akim Demaille <akim@epita.fr>
9680 * bin/autoreconf.in (&study_gettextize): New.
9681 (&autoreconf): Handle newest gettextize.

9689 2002-03-13 Akim Demaille <akim@epita.fr>
9691 * doc/autoconf.texi (Header Portability): New.
9692 Add information about stdint.h and inttypes.h from Paul Eggert.
9694 2002-03-13 Akim Demaille <akim@epita.fr>
9696 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9697 -p'.
9698 From Bob Proulx.
9700 2002-03-12 Akim Demaille <akim@epita.fr>
9702 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9703 m4_require.
9705 2002-03-11 Andreas Schwab <schwab@suse.de>
9707 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9708 does not do it if --with-lispdir is given.
9710 2002-03-08 Akim Demaille <akim@epita.fr>
9712 Version 2.53.
9714 2002-03-08 Akim Demaille <akim@epita.fr>
9716 * doc/autoconf.texi (Subdirectories): Clarify that the
9717 subdirectory should exist.

9721 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9723 2002-03-08 Akim Demaille <akim@epita.fr>
9725 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9726 aliases the actual variables, and modifications of the former
9727 affect the latter.
9729 2002-03-08 Akim Demaille <akim@epita.fr>
9731 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9732 because of C-c: have m4 output in tmp files, then mv them.

9762 parallel builds.
9764 2002-03-04 Akim Demaille <akim@epita.fr>
9766 * doc/autoconf.texi (Transforming Names): Equality between target
9767 and host is irrelevant.
9768 (Specifying Names, Canonicalizing): Remove all references to the
9769 backward compatibility hooks. Rather, collect them all into...
9770 (Hosts and Cross-Compilation): this new section.
9771 * doc/install.texi (System Type): Ditto.
9772 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9773 that `--host' implies cross-compilation.
9775 2002-03-04 Akim Demaille <akim@epita.fr>
9777 * doc/autoconf.texi (Evaluation Macros): New.
9778 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9779 useless.
9780 (_m4_foreach): Define the variant with immediate evaluation so
9781 that it contains exactly the items, not an expression which
9782 evaluation is the current item.
9783 (m4_re_string, m4_re_word): Don't over quote them.
9785 2002-03-04 Akim Demaille <akim@epita.fr>
9787 Instead of having stacking `shift's evaluated at the end, let
9788 `foreach' loops immediately evaluate them.
9790 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9791 $*. This is the n-th time I change my mind, but hopefully this is
9792 the last...
9793 (m4_lquote): New.
9794 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9795 efficient.
9796 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9797 it was only a hack for m4_text_wrap.
9798 (m4_car2): Remove, replaced by...
9799 (m4_cdr): New.
9800 (_m4_foreach): Adjust.
9801 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9802 m4_bpatsubst for clarification.
9804 2002-03-04 Akim Demaille <akim@epita.fr>

9830 2002-02-25 Akim Demaille <akim@epita.fr>
9832 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9833 From Akinori Musha.
9835 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9837 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9838 translate \r\n to \n.

9851 2002-02-07 Akim Demaille <akim@epita.fr>
9853 Fix Autoconf PR/207:
9854 AC_PREFIX_PROGRAM fails with dashed program names
9856 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9857 variable when looking for the prefix program.
9858 Now it also works for shell variables.

9872 2002-02-06 Akim Demaille <akim@epita.fr>
9874 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9875 sure not to introduce newlines in at_groups.

9878 2002-02-06 Akim Demaille <akim@epita.fr>
9880 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9881 is not available.
9883 2002-02-05 Paul Eggert <eggert@twinsun.com>

9886 Describe HP-UX cc bug workaround more accurately.

9888 not unsigned long.
9889 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9890 cross-compilers, too. This undoes some of the most recent change
9891 to this file.
9893 2002-02-05 Akim Demaille <akim@epita.fr>
9895 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9896 to make sure they are up to date when `check' is run.

9912 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9913 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9915 2002-02-05 Akim Demaille <akim@epita.fr>
9917 * bin/autom4te.in (&parse_args): Implement `frozen files are
9918 optional are the sum of the previous files on the command line'.
9919 Also, pass `--reload-state=' on them, so...
9920 (handle_m4): don't.
9921 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9922 (M4sh): Rely on M4sugar.
9923 (Autotest, M4sh, M4sugar): Use frozen files.
9925 2002-01-31 Akim Demaille <akim@epita.fr>
9927 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

9932 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non

9935 2002-01-30 Akim Demaille <akim@epita.fr>
9937 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9938 for plain code, the other for cross-compilation code. The latter
9939 is now run with GCC only.

9945 values.

9947 change AC_INIT default values.
9949 2002-01-29 Akim Demaille <akim@epita.fr>
9951 * tests/torture.at (Configuring subdirectories): Use configure.in,
9952 so that aclocal 1.4 works.
9953 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9955 2002-01-28 Akim Demaille <akim@epita.fr>
9957 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9958 needs an argument.
9960 2002-01-28 Akim Demaille <akim@epita.fr>
9962 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9963 AUTOTEST_PATH *after* it was set.
9964 Don't put `.' in the PATH: the user should be precise and `./' if
9965 needed. In addition, given that the test suite does some `cd', if
9966 `.' is in the path, the `tested programs' sections will report
9967 programs found in the test suite's directory, while during the
9968 tests (performed in their own directory), these programs are no
9969 longer visible. In other words, the results is confusing and
9970 useless.
9971 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9973 2002-01-24 Akim Demaille <akim@epita.fr>
9975 Version 2.52g.

9984 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9985 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9986 Bourne. Use /bin/sh.
9987 From Andreas Buening.
9989 2002-01-24 Akim Demaille <akim@epita.fr>
9991 * config/config.guess, config/config.sub, config/texinfo.tex:

10007 Reported by Geir Ove Myhr.
10009 2002-01-21 Akim Demaille <akim@epita.fr>

10013 2002-01-21 Akim Demaille <akim@epita.fr>
10015 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10016 message on invalid options.
10017 * bin/autom4te.in (parse_args): Don't use
10018 Autoconf::General::getopt with non valid options.
10020 2002-01-17 Jim Meyering <meyering@lucent.com>
10022 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10023 $ac_cv_exeext so we don't use an old, invalid, cached value.
10025 2002-01-11 Akim Demaille <akim@epita.fr>
10027 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
10028 Meyering.

10030 limitation.

10036 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10037 package.m4, since is really depends upon configure.ac, not
10038 configure.
10039 * doc/autoconf.texi (testsuite Scripts): Adjust.
10040 * tests/Makefile.am (package.m4): New.
10041 EXTRA_DIST it since its a source.
10043 2002-01-06 Akim Demaille <akim@epita.fr>
10045 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10046 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10047 and PACKAGE_BUGREPORT from here...
10048 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10049 arguments.
10050 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10051 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
10052 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
10053 * tests/tools.at (autoheader): Adjust.
10054 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

10075 2001-12-14 Akim Demaille <akim@epita.fr>
10077 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10078 trailing files, don't apply `-rf' to files which might not be
10079 created by configure (core, core.*, and *.core), but just `rm -f'.
10080 Suggested by Jonathan Kamens.
10082 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10084 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10086 2001-12-14 Akim Demaille <akim@epita.fr>
10088 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.

10114 Map to 1 in order to simplify its uses.
10116 2001-11-26 Akim Demaille <akim@epita.fr>
10118 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10119 Remove $filepath, useless.
10120 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10121 variables, they are really part of the tokens.
10122 Split the input line on spaces and then look for tokens.
10123 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10124 because of `lex$U.$(OBJEXT)'.
10125 (&scan_files): Use "@list" instead of join.
10126 * doc/Makefile.am (CLEANFILES): Add *.fns.
10128 2001-11-26 Akim Demaille <akim@epita.fr>
10130 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10131 Remove, replaced by...
10132 * tests/wrappl.in: Be common for all the Perl executables.
10133 In particular autoscan and autoheader want -I.
10134 * configure.ac: Adjust.

10170 top_srcdir, builddir and top_builddir.

10176 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,

10179 spelling errors.
10181 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10183 * doc/autoconf.texi (Using System Type): Add an example of `case
10184 $host' usage so people quit using `case $target' everywhere.
10186 2001-11-22 Akim Demaille <akim@epita.fr>
10188 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10189 spotted by Jim Meyering.
10191 2001-11-16 Paul Eggert <eggert@twinsun.com>
10193 This patch implements a `long double' suggestion by Oliver Kiddle.
10195 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10196 static, to catch errors if the value isn't known at compile-time
10197 and the compiler supports dynamic arrays. Change its name from
10198 `_array_' to `test_array' to avoid potential name clashes.
10199 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10200 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10201 better than double. Catch a bug in GCC 2.95.2 x86.
10202 * doc/autoconf.texi (C Compiler): Document the above.
10203 * NEWS: Likewise.
10205 2001-11-13 Akim Demaille <akim@epita.fr>
10207 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10208 hand.
10209 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10211 2001-11-13 Akim Demaille <akim@epita.fr>
10213 * lib/autotest/general.m4 (AT_INIT): After having run the test
10214 group, go back to the initial directory, not to at_suite_dir.
10216 2001-11-13 Akim Demaille <akim@epita.fr>
10218 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10219 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10220 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10221 option.
10222 (AT_CHECK_CONFIGURE): Use absolute paths.
10223 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10224 The problem is still the old one: there is no means in M4 (that I
10225 know about) to create a defining macro, because there is no means
10226 to create `$1' etc., therefore, the defining macro ``swallows''
10227 all the arguments meant to the defined macro.
10229 2001-11-13 Akim Demaille <akim@epita.fr>
10231 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10232 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10233 configure.ac.
10234 * tests/aclocal.m4: Remove, as it is no longer used.
10236 2001-11-13 Akim Demaille <akim@epita.fr>
10238 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10239 variable names when referring to a single test group, or to
10240 `suite' when referring to the whole test suite.
10241 `at_last_test' is removed: m4 compute at_format itself.
10242 (at_stdout, at_stder1, at_stderr): New variables.
10243 (AT_CHECK): Use them.
10245 2001-11-13 Akim Demaille <akim@epita.fr>
10247 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10248 in PATH.
10249 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10250 Do it as soon as a test fails, don't wait till the end of the test
10251 suite.
10252 Don't remove $as_me.[0-9]*, since these files no longer exist.
10254 2001-11-13 Akim Demaille <akim@epita.fr>
10256 * tests/tools.at: Use absolute paths, since we are no longer run
10257 in place.
10259 2001-11-13 Akim Demaille <akim@epita.fr>
10261 Now that tests are running in their own private dir, there is no
10262 need to list the files to remove at the end of tests groups.
10264 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10265 (AT_data_files, at_data_files): Remove.
10266 (AT_CLEANUP, AT_DATA): Simplify.
10267 (AT_INIT): Adjust.
10268 Remove the group dir if !debug && !failed.
10269 * tests/atspecific.m4: Adjust.
10271 2001-11-13 Akim Demaille <akim@epita.fr>
10273 Start a new layout for Autotest: `testsuite' creates
10274 `testsuite.dir' in which the at-check-line etc. files are to be
10275 found, and `testsuite.dir/003' where the test group 3 is run.
10277 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10278 at_check_line_file, at_format, at_test_normalized, at_group_dir
10279 are new variables.
10280 Create the directories.
10281 Use absolute paths for at- files.
10282 (AT_CHECK): Adjust.
10284 2001-11-11 Michael Matz <matz@kde.org>
10286 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10287 (m4_car2): New.
10288 (m4_car): Properly quote arguments.
10290 2001-11-13 Akim Demaille <akim@epita.fr>
10292 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10293 with stricter rules on LIBOBJS.
10295 2001-11-12 Paul Eggert <eggert@twinsun.com>
10297 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10298 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10299 __PROTOTYPES too.
10301 2001-11-12 Akim Demaille <akim@epita.fr>
10303 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10305 2001-11-12 Akim Demaille <akim@epita.fr>
10307 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10308 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10309 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10310 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10311 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10312 specify to what the macro should be defined (typically to 1).
10314 2001-11-12 Akim Demaille <akim@epita.fr>
10316 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10317 From Jim Meyering.
10319 2001-11-12 Akim Demaille <akim@epita.fr>
10321 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10322 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10323 definition used by Automake where LEX is +/- "${missing} lex" and
10324 `missing' itself contains variables.
10326 2001-11-12 Akim Demaille <akim@epita.fr>
10328 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10329 Now that M4sh pushes BODY, the comments were output at the end of
10330 the test suites.
10332 2001-11-08 Akim Demaille <akim@epita.fr>
10334 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10335 that we can trace macros from aclocal.m4.
10336 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10337 obsoleted, and redirect to the former anyway.
10338 Reported by Ralf Corsepius.
10340 2001-11-08 Akim Demaille <akim@epita.fr>
10342 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10343 processed only if present.
10344 * tests/torture.at (Configuring subdirectories): Use autoreconf
10345 instead of successive calls to autoconf.
10346 Add a nonexistent subdirectory to exercise the patch above.
10347 Reported by Ralf Corsepius.
10349 2001-11-08 Kevin Ryde <user42@zip.com.au>
10351 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10352 doesn't accept .S files.
10354 2001-11-07 Akim Demaille <akim@epita.fr>
10356 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10357 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10358 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10359 * bin/autom4te.in (warn_forbidden): New.
10360 (handle_output): Use it.
10361 Read m4_pattern_forbid with messages.
10363 2001-11-05 Akim Demaille <akim@epita.fr>
10365 * bin/autom4te.in (--normalize): Remove.
10366 * lib/autom4te.in: Adjust.
10368 2001-11-05 Akim Demaille <akim@epita.fr>
10370 * tests/Makefile.am (testsuite): Rename this target as...
10371 ($(TESTSUITE)): this.
10372 From Nicolas Joly.
10374 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10376 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10377 the --prefix option, also remove it's argument.
10379 2001-11-05 Akim Demaille <akim@epita.fr>
10381 * doc/autoconf.texi (testsuite Invocation): Update.
10382 (Writing testsuite.at): Update.
10384 2001-11-03 Akim Demaille <akim@epita.fr>
10386 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10388 2001-11-03 Akim Demaille <akim@epita.fr>
10390 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10391 (&file_name_is_absolute): New, wrappers around routines from
10392 File::Spec.
10393 Use and export them.
10394 (&find_configure_ac): Optionally take a directory where to look at.
10395 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10396 the arguments.
10397 Default @ARGV to `.', not find_configure_ac.
10398 (&autoreconf): Argument is a directory.
10399 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10400 * doc/autoconf.texi (autoreconf Invocation): Update.
10402 2001-11-03 Akim Demaille <akim@epita.fr>
10404 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10405 (@export_forward_subs): New.
10406 Add basename, dirname, and fileparse.
10407 (@EXPORT): Adjust.
10408 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10409 Don't look for aclocal flags if we already know aclocal is not
10410 used.
10411 Move aclocal.m4t only if it exists.
10412 Reported by Ezra Peisach.
10414 2001-11-03 Akim Demaille <akim@epita.fr>
10416 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10417 passed on command line, defaulting to ./configure.ac if present.
10418 (&maybe_autoreconf, File::Find): Remove, unused.
10419 (&autoreconf): If autoconf is not used, don't try to trace.
10421 2001-11-02 Akim Demaille <akim@epita.fr>
10423 * configure.ac: Bump to 2.52g.
10425 2001-11-02 Akim Demaille <akim@epita.fr>
10427 Version 2.52f.
10429 2001-11-02 Akim Demaille <akim@epita.fr>
10431 * config/config.guess, config/config.sub, doc/standards.texi:
10432 * config/lispdir.m4: Update from masters.
10433 * configure.ac: Bump to 2.52f.
10435 2001-11-02 Akim Demaille <akim@epita.fr>
10437 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10438 Don't run aclocal when aclocal.m4 is not from aclocal.
10439 From Ezra Peisach.
10440 Don't run libtoolize and gettextize if --install is not given.
10442 2001-11-01 Paul Eggert <eggert@twinsun.com>
10444 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10445 be invoked before _AS_LINENO_PREPARE.
10446 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10447 than character ranges.
10449 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10450 invoking AS_BASENAME. Set the locale variables to 'C' if
10451 possible, as POSIX requires this to get the traditional
10452 behavior.
10453 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10455 2001-10-31 Paul Eggert <eggert@twinsun.com>
10457 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10458 with {}, as that triggers a bug in Bash 2.05.
10460 (_AS_LINENO_PREPARE): Use Sed rather than
10461 Awk. Fix the sed prepass to work even if there are multiple
10462 instances of $LINENO on the same line. Do not substitute for
10463 other variables like $LINENOT. Do not check file dates; such a
10464 check is unreliable on sufficiently fast machines, and removing
10465 the check makes the code simpler and more reliable. Check for
10466 output and chmod failures.
10468 * doc/autoconf.texi (Special Shell Variables): Document
10469 the above.
10471 2001-10-31 Akim Demaille <akim@epita.fr>
10473 * tests/Makefile.am (atconfig): Remove this target, Automake
10474 handles it now.
10476 2001-10-31 Akim Demaille <akim@epita.fr>
10478 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10479 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10480 provided, while it is optional.
10481 * configure.ac: Adjust.
10483 2001-10-26 Paul Eggert <eggert@twinsun.com>
10485 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10486 lib/Autom4te/Struct.pm:
10487 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10488 with 5.005_02.
10490 * doc/autoconf.texi (Special Shell Variables): Document some
10491 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10493 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10494 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10495 eval $LINENO is not portable in practice.
10497 2001-10-24 Akim Demaille <akim@epita.fr>
10499 * lib/Autom4te/General.pm (backname): New.
10501 2001-10-24 Akim Demaille <akim@epita.fr>
10503 * m4/: Remove, merged into...
10504 * config/: here.
10506 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10508 * doc/autoconf.texi (Shellology): Mention the problems with bash
10509 2.05's use of ANSI quoting in its `set' builtin.
10511 2001-10-22 Paul Eggert <eggert@twinsun.com>
10513 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10514 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10515 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10516 POSIX decided to standardize on the int flavor of strerror_r.
10517 Always do char* test, as there's no reason not to.
10518 Assign to a char* var, to catch strerror_r that returns int*.
10520 * doc/autoconf.texi (Particular Functions):
10521 Document the above changes. Also, document the fact that
10522 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10524 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10526 2001-10-20 Akim Demaille <akim@epita.fr>
10528 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10529 the executable was missing from the log.

10533 * lib/Autom4te/General.pm (&update_file): If destination is
10534 unchanged, remove the source.
10535 (&up_to_date_p): Don't be verbose, be debug.
10536 * bin/autoreconf.in: No longer support --m4dir.
10537 (&autoreconf): Display the full path of the configure.ac we are
10538 studying.
10539 Trace it only once.
10540 Be sure to honor --force with gettextize.
10541 Always run aclocal.
10542 * doc/autoconf.texi: Adjust.
10544 2001-10-20 Akim Demaille <akim@epita.fr>
10546 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10547 Remove, dead.
10548 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10549 `intl' is already present, as it refuses unless --force.
10550 (&parse_args): Use -I, --include instead of the old Autoconf
10551 options.
10552 ($localdir, $autoconf_dir): Remove.
10553 (@include): New.
10554 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10556 2001-10-19 Jens Petersen <petersen@redhat.com>
10558 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

10563 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
10564 file in @configure_input@.
10565 Don't mention `automatically' in addition to `generated'.
10566 * tests/torture.at (#define header templates): Adjust.
10568 2001-10-19 Akim Demaille <akim@epita.fr>
10570 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10571 comment, explain how to install automatic mode selection.
10572 From Russ Allbery.
10574 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10576 * bin/autoreconf.in (autoreconf): Display the path to the
10577 configure.ac being studied.
10579 2001-10-18 Paul Eggert <eggert@twinsun.com>
10581 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10582 long, to work around a bug in the HP C compiler version HP92453-01
10583 B.11.11.23709.GP.
10585 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10586 (AS_BASENAME_EXPR): New macro.
10587 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10588 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10589 and fall back on 'sed' only if the other two fail. This makes
10590 AS_BASENAME act more like AS_DIRNAME.
10591 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10592 contains white space.
10593 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10594 Use AS_DIRNAME, since I think it's now DOS-friendly.
10595 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10596 Allow "dirname //FOO" to return either / or //, as POSIX allows
10597 either behavior.
10599 2001-10-10 Akim Demaille <akim@epita.fr>
10601 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10602 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10603 From Eric Sharkey.
10605 2001-10-10 Akim Demaille <akim@epita.fr>
10607 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10608 m4_define, since...

10623 transition code.
10625 2001-10-08 Akim Demaille <akim@epita.fr>
10627 * bin/autoreconf.in (&autoreconf): Remove debugging code.
10628 (&parse_args): Pass verbosity/debugging options to subtools when
10629 --debug, not when --verbose.
10630 * lib/autom4te.in (Autoreconf-preselections): New.
10631 (Autoconf): Use it.
10633 2001-10-08 Akim Demaille <akim@epita.fr>

10647 bother with $force since...
10648 * lib/Autom4te/General.pm: does.

10653 * configure.ac: Adjust.

10672 * lib/m4sugar/m4sh.m4, lib/m4sugar/m4sugar.m4, tests/atspecific.m4,
10673 * tests/torture.at: Rename m4_regexp, m4_patsubst, and m4_match to

10739 ourselves with CONFIG_SHELL.
10741 2001-10-05 Paul Eggert <eggert@twinsun.com>
10743 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10744 doesn't exist. Remove *.tmp, as a .tmp file is created during the

10786 compatibility with POSIX shells.

10828 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10860 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10861 (AC_PROG_CPP requires AC_PROG_CC): here and...
10862 * tests/fortran.at (GNU Fortran 77): there.
10863 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10864 AC_TRY_RUN is about compilation, not shell commands.

10869 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10870 Raja R Harinath:
10871 Be sure to detect when $LINENO always returns the same value.
10872 Look for the original script, basename($0) is certainly not
10873 enough.
10874 Pass the CLI arguments to `$as_me.lineno'.

10895 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10896 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10897 builddir, buildpath, top_builddir, and top_buildpath.
10898 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10899 the current directory.

10924 * doc/autoconf.texi (Common Shell Constructs): Rename as...

10971 2001-09-22 Akim Demaille <akim@epita.fr>

10976 `$LINENO' support replacement when not supported.
10977 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

10988 character (u: -> ue) in a code comment.
10989 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know

11016 * lib/autotest/general.m4: Replace occurrences of ':' in
11017 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
11019 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

11024 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
11026 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

11042 CR issues on DOSish systems).
11044 2001-09-19 Akim Demaille <akim@epita.fr>
11046 * lib/autotest/general.m4: Englishoes.
11047 From Tim Van Holder and Alexey Mahotkin.
11049 2001-09-18 Paul Eggert <eggert@twinsun.com>
11051 * doc/autoconf.texi (Common Shell Constructs): New node,
11052 documenting AS_DIRNAME.
11053 (Limitations of Usual Tools): Refer to it when discussing dirname.
11054 Also, update discussion of POSIX standard to reflect latest draft.
11056 * lib/autoconf/c.m4:
11057 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11059 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11060 Do not pass a first argument with leading '-'
11061 to expr, by parenthesizing initial integers that might be negative.
11063 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11064 now merely checks whether it is an error to pass an argument
11065 to getpgrp.
11067 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11068 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11069 whether it is a (compile-time) error to pass an argument to
11070 getpgrp. This simpler test supports the revised documentation,
11071 and is all that AC_FUNC_GETPGRP's users really need.
11073 2001-09-18 Akim Demaille <akim@epita.fr>

11086 correctly.
11087 Add test for AS_BASENAME.
11088 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11089 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11090 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11091 * tests/base.at: Fixed the expected responses. The old ones were
11092 one line out...
11093 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11094 the documentation claims it should (and how it behaved in 2.13).
11096 2001-09-18 Akim Demaille <akim@epita.fr>
11098 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

11107 Use `m4_PACKAGE_STRING'.
11108 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11109 the only optional argument is the name of the test suite.
11110 Expect `package.m4' to define the package signature.
11111 * lib/autom4te.in (Autotest): Add `package.m4?'.
11112 * tests/Makefile.am (package.m4): New.
11113 * tests/suite.at: ifnames is a victim.
11115 2001-09-18 Akim Demaille <akim@epita.fr>
11117 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11118 AC_LIBSOURCE, AC_CONFIG_FILES.
11119 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11120 program version string doesn't match the package's.

11132 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):

11134 the expression in an extra function before these includes. Call
11135 fprintf "%d" only after ensuring the argument is of type 'int'.

11140 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11141 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11142 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11143 when they don't exist.
11145 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11146 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11147 need it.
11149 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11150 version with the version used by fileutils 4.1, except use
11151 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11152 we don't need it.
11154 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11156 2001-09-13 Akim Demaille <akim@epita.fr>

11196 * lib/autotest/general.m4 (AT_INIT): Create and remove
11197 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

11287 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

11308 2001-09-05 Akim Demaille <akim@epita.fr>
11310 Be ready to handle filenames as stupid as `dnl.at', for if even
11311 the maintainer is dumb enough to do that...
11313 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11314 excellence in M4 quotation: consider `__file__' is active.
11316 And BTW, when invoking m4, pass the --include in the right order:
11317 the wrong one.
11319 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11320 4m.

11344 CVS GNU M4 doesn't like `undefine(undefined)'.
11346 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11347 New, extracted from main.
11348 Use IO::File wherever possible.
11349 (input.m4): Be constant, use -I instead of hard coding $tmp.
11350 Therefore be a quoted heredoc.
11351 Don't invoke `_au_disable', since ac was not loaded, but just
11352 `unm4.m4'.
11354 2001-08-31 Akim Demaille <akim@epita.fr>
11356 Version 2.52d.

11379 2001-08-31 Akim Demaille <akim@epita.fr>
11381 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11382 (testsuite Scripts): There is no such thing as `atconfig.in'.
11383 And actually one diagram is missing: test suite runtime.
11385 2001-08-31 Akim Demaille <akim@epita.fr>
11387 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11388 inverse order.
11390 2001-08-31 Akim Demaille <akim@epita.fr>
11392 * bin/autoupdate.in (@include): `installcheck' revealed the path
11393 to m4sugar was lacking!
11395 2001-08-31 Akim Demaille <akim@epita.fr>
11397 * man/Makefile.am (.x.1): We really have to pass
11398 autom4te_perllibdir.
11400 2001-08-31 Akim Demaille <akim@epita.fr>
11402 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11403 debug scripts, in particular passing explicitly listed tests to
11404 run is stupid.
11406 2001-08-31 Akim Demaille <akim@epita.fr>
11408 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11409 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11410 Use directly autom4te, not autoconf.

11413 2001-08-31 Akim Demaille <akim@epita.fr>
11415 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

11424 * bin/autom4te.in (&parse_args): Die on unknown languages.
11425 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11426 need for autoconf.
11427 Promote --include over --macrodir and other obsolete options.
11429 2001-08-31 Akim Demaille <akim@epita.fr>
11431 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

11434 `print $out' doesn't print `$_' but `$out'.
11435 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11436 (autoheader): Pass --force since the test suite goes too fast for
11437 the time stamps.
11438 Adjust to the new autoheader messages.
11440 2001-08-31 Akim Demaille <akim@epita.fr>
11442 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

11452 Drop AC_MACRODIR dead for real.
11453 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11454 `autoheader: `config.hin' is created'.
11455 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11457 2001-08-31 Akim Demaille <akim@epita.fr>
11459 * bin/autoheader.in: Rewrite in Perl.

11462 2001-08-31 Akim Demaille <akim@epita.fr>
11464 * bin/autoconf.in (--include, -I): New option.
11465 Map --localdir, --autoconf-dir onto it.
11466 Forward autom4te's options instead of interpreting them.
11467 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11468 There is no such envvar since the inception of autom4te.cfg.
11469 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11470 * bin/autoupdate.in: Adjust, and perform more control.
11471 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.

11474 2001-08-31 Akim Demaille <akim@epita.fr>
11476 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11477 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11478 optionally `FILE'.
11479 Use -e, not -f, since /dev/null for instance is OK.
11480 (&parse_args): Adjust.
11481 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11483 2001-08-31 Akim Demaille <akim@epita.fr>
11485 * configure.ac: Also find tested executables in bin.
11486 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11487 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11488 installed peer executables, only PATH is allowed to resolve it.
11489 Pass `autoconf_dir' via options, not via invisible envvars.
11490 * lib/Autom4te/General.pm (&find_peer): Remove.
11491 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11492 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11493 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11494 find the executables for it.
11495 * tests/Makefile.am: Major cleanup. Too lazy to document...
11496 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11497 We only need PERL.
11498 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11499 indeed related to running the test suite, while passing
11500 --autoconf-dir and others is related to running non installed
11501 Autoconf executables. So don't do that, leave it to...
11502 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11503 * tests/autoscan: New.
11504 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11505 refer to library files: rely on --language.
11507 2001-08-29 Akim Demaille <akim@epita.fr>
11509 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

11512 2001-08-29 Akim Demaille <akim@epita.fr>
11514 * doc/autoconf.texi: Strip the @nodes.
11515 Suggested by Paul Eggert.

11518 2001-08-29 Akim Demaille <akim@epita.fr>
11520 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11521 Suggested by Paul Eggert.
11523 2001-08-29 Akim Demaille <akim@epita.fr>
11525 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11526 download in a tmp dir.
11528 2001-08-29 Akim Demaille <akim@epita.fr>
11530 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11542 * bin/autoconf.in: Simplify and adjust.
11543 * tests/Makefile.am (AUTOMAKE): Use --set.
11544 * tests/atlocal.in: Adjust.
11545 * BUGS: distcheck and check are weak.
11547 2001-08-29 Akim Demaille <akim@epita.fr>
11549 * lib/autotest/general.m4: Use
11550 foo=`(command) 2>/dev/null`
11551 not
11552 foo=`command` 2>/dev/null
11553 (at-devnull): Rename as...
11554 (AT-devnull): this.
11555 (--clean): Remove AT-* files too.
11556 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11557 Reported by Nicolas Joly.

11572 (AT_INIT): Check for the `times' builtin before using it.
11573 Support test ranges as arguments to the testsuite.
11574 Have -e imply -d as the help text suggested.
11576 2001-08-27 Akim Demaille <akim@epita.fr>

12031 2001-08-11 Paul Eggert <eggert@twinsun.com>
12033 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

12067 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12069 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12070 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12071 * doc/autoconf.texi (C Compiler Characteristics): Update
12072 documentation for AC_C_BIGENDIAN.
12074 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12076 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12077 magic values from an object file when cross-compiling.
12078 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12080 2001-08-10 Akim Demaille <akim@epita.fr>
12082 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12083 effects.
12084 Suggested by Russ Allbery.
12086 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12088 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12089 current $prefix to the sub-configures.
12091 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12093 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12094 extension (needed on BeOS). Reported by Guido van Rossum.
12096 2001-08-09 Akim Demaille <akim@epita.fr>
12098 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12100 2001-08-07 Akim Demaille <akim@epita.fr>
12102 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12103 removed.
12104 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12105 No need to remove the files before and after the each test, before
12106 each test and at the end of the suite is enough.
12107 Display only the children `times', not the shell's.
12108 If the test failed or was skipped, at-times is not available.
12110 2001-08-07 Akim Demaille <akim@epita.fr>
12112 Always produce testsuite.log, including when there are no
12113 failures. This helps getting information on skipped tests, and
12114 duration of the tests. Err, implement the latter btw.
12116 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12117 Dump information on the first run of each test.
12118 (AT_CLEANUP): Create `at-times' containing the duration of the
12119 test group.
12121 2001-08-07 Akim Demaille <akim@epita.fr>
12123 The use of `dumpstat' revealed that `len' was used although it
12124 should not. m4_text_wrap was using it, but in the Autoconf world
12125 where it is legal. Hence (i) test M4sh in its own world, not
12126 Autoconf's, and (ii), ahem, fix the bug :)
12128 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12129 does not like `' instead of [].
12130 (AT_INIT): Forbid `^_?AT_'.
12131 And don't output such tokens.
12132 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12133 `script.as', and `autom4te.cache'.
12134 Remove `empty' and `macro' which are no longer used.
12135 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12136 * tests/m4sugar.at: Use it.
12137 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12139 2001-08-07 Akim Demaille <akim@epita.fr>
12141 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12143 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12145 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12147 2001-08-04 Akim Demaille <akim@epita.fr>
12149 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12150 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12151 AC_TRY_LINK.
12152 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12153 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12154 (AC_F77_MAIN): Likewise.
12156 2001-08-04 Akim Demaille <akim@epita.fr>
12158 Don't rely on M4sugar outputting the patterns in files, since we
12159 might process the output _without_ running m4, hence without these
12160 files.
12162 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12163 * bin/autom4te.in (@Request::includes): Remove, unused.
12164 (@Request::source): Rename as...
12165 (@Request::input): this.
12166 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12167 (&handle_output): Fetch the patterns from the traces.
12168 `$forbidden' and `$allowed' are constant: use m//o.
12169 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12170 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12172 2001-08-04 Akim Demaille <akim@epita.fr>
12174 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12175 autoconf', i.e., in addition to caching traces, cache the output.
12177 * bin/autom4te.in (Request::cache): Rename as...
12178 (Request::id): this.
12179 ($cache, $icache, $tcache, $ocache): New.
12180 (&handle_m4): Save M4 output in the cache instead of $tmp.
12181 (&handle_output): Adjust.
12182 (&up_to_date_p): Check that the output cache is up to date too.
12183 (top level): Run `&handle_m4' iff force or the cache is invalid.
12184 Run `&handle_output' if the output cache is more recent.
12186 2001-08-04 Akim Demaille <akim@epita.fr>
12188 * bin/autom4te.in ($force): New.
12189 (&parse_args, &print_usage): -f, --force is a new option.
12190 (&handle_output): CPP directives might have spaces after `#'.
12191 (&parse_args): The first file only can be frozen.
12193 2001-08-04 Akim Demaille <akim@epita.fr>
12195 Don't let autom4te compute the `include' traces several times:
12196 first check that the trace cache file is up to date, and then
12197 compare its timestamp with that of the output.
12199 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12200 the preamble. Don't require 5.005 as Autom4te::General does it,
12201 and better yet (use `use', not `require'!).
12202 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12203 Class::Struct as Autom4te::Struct.
12204 * lib/Autom4te/General.pm (File::stat): Use it.
12205 (&mtime): New, export it.
12206 * bin/autom4te.in: Use it.
12207 Declare `$req' is invalid if it is outdated.
12208 Don't declare it valid before saving it if something went wrong.
12210 2001-08-04 Akim Demaille <akim@epita.fr>
12212 Autom4te shall not encode Autoconf data, and preselecting traces
12213 must be proposed to the users.
12215 * bin/autom4te.in (@required_trace): Remove.
12216 (@preselect): New.
12217 (&parse_args, &print_usage): -p, --preselect is a new option.
12218 (&up_to_date_p): Adjust.
12219 * bin/autoconf.in: Preselect some Autoconf macros.
12221 2001-08-04 Akim Demaille <akim@epita.fr>
12223 * tests/tools.at (autoconf --trace: user macros): Check traces on
12224 macros invoked without arguments, and macros invoked with multiple
12225 lines arguments.
12227 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12229 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12230 arguments.
12232 2001-08-03 Akim Demaille <akim@epita.fr>
12234 * bin/autoconf.in ($@): Work around the usual sh bug.
12235 From Nicolas Joly.
12237 2001-08-03 Akim Demaille <akim@epita.fr>
12239 Clean up the handling of the M4 builtins tracing exception.
12241 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12242 trace requests.
12243 (@m4_builtins): Rename as...
12244 (@m4_builtin): this.
12245 (%m4_builtin_alternate_name): New.
12246 (&parse_args): Complete the trace requests with alternate names.
12247 (&handle_traces): Hence no longer do it here.
12248 (&trace_requests): Remove, unused.
12250 2001-08-03 Akim Demaille <akim@epita.fr>
12252 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12253 m4_if, and m4_wrap.
12255 2001-08-03 Akim Demaille <akim@epita.fr>
12257 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12258 (m4_divert_pop): Dump the whole diversion stack when a diversion
12259 mismatch happens.
12260 * bin/autom4te.in (&handle_output): Remember of the first
12261 occurrence of a possibly undefined macro, not the last.
12262 Complain about the possibly undefined macros in the same order as
12263 the appear in the output.
12264 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12265 * tests/tools.at (autoconf: forbidden tokens, basic)
12266 (autoconf: forbidden tokens, exceptions): No longer sort
12267 autoconf's stderr, as it is now deterministic.
12268 Check that `dnl' is caught.
12270 2001-08-01 Akim Demaille <akim@epita.fr>
12272 * configure.ac: Bump to 2.52c.
12274 2001-08-01 Akim Demaille <akim@epita.fr>

12284 2001-08-01 Akim Demaille <akim@epita.fr>

12287 `die'.
12288 (&END): New.
12289 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12290 `END', as `Autom4te::General::END' will be triggered.
12291 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12292 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12727 cross-language link tests can be performed successfully.
12728 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12729 after $LIBS, for consistency; this should be the general rule since
