37 status of rm so we know when it failed.
38 If cleaning of test dir failed before running the test, warn.
39 Output the line separator in verbose mode before the warning
40 to make clear the warning belongs to the following test.

65 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
67 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
68 input from /dev/null in awk test, so even Solaris /usr/bin/awk
69 will not wait for input with a script containing only a BEGIN

105 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
106 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
107 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
108 substitution will still be done by the special code.
109 Report by Jim Meyering.

117 * doc/autoconf.texi (Setting Output Variables): Mention that
118 all non-NUL characters are ok in substituted values.
119 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
120 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
121 carriage return for $AWK, needed for BSD awk.

131 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
133 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
134 early on the reader side, drop stderr of the input to avoid
135 `broken pipe' error output; this may happen even with shell
136 builtin `echo' of some bash versions. Reports by Ian Macdonald
137 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
139 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
141 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
142 separate items of `ac_user_opts', to avoid long lines.

151 Fix some wording problems noted by Paolo Bonzini in:
152 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
153 * doc/autoconf.texi (Signed Overflow Examples): Give more
154 discussion about the allow_superuser_privileges example,
155 and change it a bit to make things clearer.
156 (Optimization and Wraparound): Clarify whether the compiler
157 will generate an infinite loop for the example derived from
158 Autoconf's mktime test.
159 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
160 Also, clarify unsigned multiplication overflow.
162 2007-01-04 Eric Blake <ebb9@byu.net>
164 * bin/Makefile.am (RELEASE_YEAR): New macro.
165 (edit): Use it to supply correct copyright year to scripts.
166 * bin/autoconf.as (version): Use it.
167 * bin/autoheader.in ($version): Likewise.
168 * bin/autom4te.in ($version): Likewise.

174 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
176 * doc/autoconf.texi (Integer Overflow): Revised based on today's
177 feedback. The most important changes document what happens when
178 you convert an out-of-range value to a signed integer type, and
179 say that (sum < a) != (b < 0) reliably detects overflow when sum =
182 * doc/autoconf.texi (Integer Overflow): Greatly expand and
183 rewrite, taking notions from the recent discussion on the gcc and
184 autoconf mailing lists; please see
185 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
186 and follow the many links.
187 (Integer Overflow Basics, Signed Overflow Examples):
188 (Optimization and Wraparound, Signed Overflow Advice):
189 (Signed Integer Division): New sections.
191 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
193 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
194 preprocessor macro arguments in traced name.
195 * doc/autoconf.texi (Defining symbols): Document longstanding
196 support for AC_DEFINE-ing macros with arguments, and document
197 behavior when the same variable has multiple AC_DEFINEs.
198 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
199 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
200 macros directly, giving much shorter and simpler code.
202 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
204 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
205 space before "$ac_configure_args" to prevent a 'config.status
206 --recheck' failure if ac_configure_args doesn't contain a leading
207 space. This works around a problem with the XEmacs configure.ac,
208 which uses the (undocumented) ac_configure_args variable
209 inconsistently with Autoconf.
211 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
213 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
214 Include <limits.h>, and use its INT_MAX to rewrite the
215 j loop so that it does not overflow 'int'. Problem reported by
217 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
218 Play it safe by shifting left by 1 rather than multiplying by 2,
219 as GCC is less likely to optimize this away when the value
220 is signed (when it assumes overflow leads to undefined behavior).
221 Also, don't assume time_t uses two's complement.
223 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
225 * tests/torture.at (Substitute a 2000-byte string): Avoid using
226 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
227 dumps core on it. Report by Tim Rice.
229 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
231 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
232 --disable-option-checking to --help output even when
233 AC_PRESERVE_HELP_ORDER is not used.
234 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
235 --with argument, rather than argument with [-.] replaced by
237 * NEWS: Fix typo in previous change; the news was in the
240 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
242 * NEWS: Warnings are now generated by default for unknown
243 --enable-* and --with-* options.
244 * doc/autoconf.texi (Option Checking): Renamed from
245 (Configure Option Checking). Tighten up the wording a bit.
246 (External Software, Package Options): Cross-reference to Option
247 Checking, and use this to shorten our section.
248 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
249 "$x" to test "x$foo" != x.
250 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
251 Don't warn if $enable_option_checking is "no".
252 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
253 ac_unrecognized_opts to the empty string.
254 Don't echo the unrecognized opts, as this might mishandle
255 backslashes or leading -.
256 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
257 usage next to the other --disable-FEATURE options in the
260 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
262 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
263 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
264 Print warning for unrecognized --with and --enable options
265 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
266 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
267 Disable option checking when subdirs are configured.
268 (AC_OUTPUT): If warnings are enabled, print warning about
269 unrecognized --with and --enable options at the end of
270 the configure output (as well as at the beginning).
271 * doc/autoconf.texi (Option Checking): New node.
272 Document new option warning functionality.
274 2006-12-16 Eric Blake <ebb9@byu.net>
276 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
277 * NEWS: Start news for current version.
279 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
281 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
282 Define HAVE_GETMNTENT to 1, not to the empty string.
283 Problem originally reported by Jochen Friedrich in
284 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
286 This change prompted by a problem report by Andrey Simonenko in
287 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
288 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
289 object-like macros only, in the traditional portable character
291 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
292 Warn about attempts to define things that are not identifiers.
293 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
294 awful hack that AC_DEFINEd macro names containing parentheses.
296 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
298 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
299 too drastic, even if Texinfo in theory requires it for info mode.
301 (config.status Invocation): Renamed back from Recreating a
303 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
304 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
306 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
308 * NEWS: Version 2.61a.
310 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
311 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
313 * NEWS: Document changes with echo and printf, and the lack
314 of limits on the total size of multi-line values of substituted
315 variables, and the AC_FUNC_FSEEKO fix.
317 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
319 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
320 Writing configure.ac.
321 (Autoconf Input Layout): Renamed from configure.ac Layout.
322 (Recreating a Configuration): Renamed from config.status Invocation.
323 (Obsolete Recreation): Renamed from Obsolete config.status Use.
324 (acconfig Header): Renamed from acconfig.h.
325 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
326 (Writing Testsuites): Renamed from Writing testsuite.at.
327 (Autom4te Cache): Renamed from autom4te.cache.
329 * BUGS: Remove mention of VPATH problem, since it's now documented
330 not to be a bug in the Autoconf build procedure itself, but rather
331 a problem with the proprietary `make' programs.
333 * doc/autoconf.texi (Build Directories): Add a cross reference
336 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
337 * doc/standards.texi: Sync from gnulib.
339 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
340 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
341 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
342 generated automatically.
344 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
346 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
347 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
348 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
350 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
352 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
353 `CEOF$ac_eof' special marker, the awk script cannot contain a
354 line matching `^CEOF', so this is not needed any more.
355 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
356 special marker in the test.
358 2006-12-06 Stepan Kasal <kasal@ucw.cz>
360 * tests/tools.at (autom4te preselections): Use `find -newer';
361 remove one of the sleeps.
363 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
364 more readable, using ...
365 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
367 * doc/autoconf.texi (autoheader Invocation): Do not double-
368 quote the parameter of `AH_BOTTOM' in the example.
370 2006-12-05 Stepan Kasal <kasal@ucw.cz>
372 * doc/autoconf.texi (Configuration Headers): Remove the
373 example with multiple input files.
374 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
375 multiple input files.
377 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
379 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
380 creating the awk substitution script, handle one input line at a
381 time, so that the maximum length of a substituted (multi-line)
382 value is not limited by the size of the sed pattern space.
383 The trade-off is a slightly repetitive sed script.
384 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
385 can only have up to 7 characters, due to Solaris 10 /bin/sed.
386 * tests/torture.at (Substitute a 2000-byte string): Increase the
387 test with several long lines, they should not be caught by sed
390 * tests/tools.at (autom4te preselections): New test, to flag
391 entries missing from autom4te.cfg.
392 Report by David Byron <dbyron@hheld.com>.
394 * tests/torture.at (Substitute a 2000-byte string): Actually use
395 AC_PROG_AWK, so the last change works as intended.
396 (Substitute and define special characters): Likewise.
397 (Substitute a newline): Likewise.
399 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
400 instead of `awk' consistently.
401 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
402 * tests/torture.at (Torturing config.status): Test both the
403 result of AC_PROG_AWK and plain awk.
404 (Substitute a 2000-byte string): Likewise.
405 (Substitute and define special characters): Likewise.
406 (Substitute a newline): Likewise.
408 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
410 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
411 can be assigned to a function pointer. Problem reported by
412 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
413 part of a patch by Ralf Wildenhues in that same bug report.
415 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
417 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
418 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
420 2006-12-01 Eric Blake <ebb9@byu.net>
422 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
423 cross-compiling from cygwin to mingw.
424 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
425 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
426 to lib/autoconf/c.m4.
428 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
430 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
431 string for more reliable failure. Wrap the entire test that
432 causes the broken Solaris printf to dump core, in a subshell,
433 so the segmentation fault message is reliably suppressed.
434 Fix shell expansion errors by using /usr/ucb/echo always;
435 avoid an error on systems without it by another subshell.
436 Avoid m4 expansion of `$1'. Set the zeroth argument of the
437 subshell-$as_echo to `as_echo', for better error message.
439 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
441 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
442 `BASH_SOURCE' contain a newline, set them to empty, as they may
445 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
447 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
448 years and is too hard to maintain now. The last straw was
449 reported by Jerker Baeck in
450 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
451 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
452 * doc/autoconf.texi (Particular Functions): Move
453 AC_FUNC_SETVBUF_REVERSED from here...
454 (Obsolete Macros): ... to here. Say that it does nothing now.
455 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
456 Turn into (almost) a no-op.
458 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
460 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
461 These macros are obsolescent and new applications shouldn't need them.

476 * Makefile.am: Put only a single '#' into the copyright notice,
477 so that it's also present in the output file. Standardize wording
478 in makefile copyright notices to match GNU coding standards.

494 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
495 in the sed script that mangles the awk script: delete up to the
496 first exclamation mark only.
497 * tests/torture.at (Substitute and define special characters):
500 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
502 Rewrite config files generation: avoid quadratic growth in
503 the number of substituted variables by using awk instead of sed
504 for the bulk of the substitutions.
505 * NEWS: Mention this.
506 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
507 forbidden in the output (and thus input) file.
508 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
509 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
510 generate just one large awk script for substitutions,
511 eliminating much of the earlier complexity, while adding some
512 new complexity. Only expand the substitution templates at
513 configure time, for smaller configure script size. If
514 _AC_SUBST_FILES are used, test 'awk' for working getline support
515 at config.status time. If absent, interpolate through the
516 shell. The awk script was written with much help
517 from Paolo Bonzini and Paul Eggert.
518 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
519 (_AC_SED_FRAG_NUM): Likewise.
520 (_AC_SUBST_CMDS): Renamed from...
521 (_AC_SED_CMDS): ...this.
522 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
523 * tests/torture.at (Substitute a 2000-byte string): Also
524 substitute a line with 1000 words, and a variable with several
526 (Substitute and define special characters): Test awk special
527 characters, and put substitution input strings `@foo@' in the
528 output, to test that no recursion happens; test several other
529 combinations from Paolo Bonzini.
531 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
533 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
534 that replaced echo with AS_ECHO where this wasn't necessary.
535 Problem reportd by Ralf Wildenhues.
536 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
537 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
538 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
540 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
542 * lib/freeze.mk (GREP): Removed, no need to initialize this.
544 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
546 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
547 that traditional Awk lacks 3-arg "split". It has it.
548 Mention that FS must be a single character, and a few other
549 99-byte limits of traditional Awk.
550 Mention that if (i in a) doesn't work with traditional Awk.

556 (Newline-CODE-BS-newline in command):
557 (Single-quote-BS-newline in command):
558 (Single-quote-newline-BS-newline in command):
559 Use printf '%s\n' instead of echo, for portability to hosts
560 where echo interprets backslashes. This will break on hosts
561 that lack printf, but for now let's assume all such hosts
562 are dead (if not, we should get reports of test failures).
564 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
566 'echo' has some portability problems, when given a first argument
567 with a leading '-', or when given any argument containing '\'.
568 Avoid using 'echo' in these cases.

597 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
598 Don't use ECHO_T, since ECHO_N is now reliable.
599 * lib/autotest/general.m4 (AT_INIT): Likewise.
600 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
601 rather than using a here-document to put the script into a file.
602 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
604 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
605 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
606 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
607 bug, but we might as well stop using ECHO_N and ECHO_C internally.
608 * lib/autotest/general.m4 (AT_SETUP): Likewise.

610 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
611 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
612 operand, as AS_ECHO requires. Avoid double file name expansion.
613 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
614 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
615 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
616 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
617 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
618 Double-quote strings that would otherwise contain M4 comments.
619 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
621 * configure.ac (AC_INIT): Bump to 2.61a.
624 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
628 * configure.ac (AC_INIT): Bump to 2.61.
631 * tests/autotest.at (Macro with backslash in a test title):
632 Comment out for now, as this tests neither fails nor passes
633 reliably. Problem reported by Ralf Wildenhues.
635 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
637 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
638 in previous change, which caused test failures.

707 first argument may also contain dots.
709 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
711 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
712 benefit of platforms like Solaris+GCC where it is common to have a
713 non-working g++ installation.
715 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

750 Handle special characters in test case titles correctly.
751 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
753 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
754 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST

756 ./micro-suite -l and the title in micro-suite.log.
757 (Backquote in a test title,
758 Single-quote in a test title,
759 Double-quote in a test title): Don't expect failure anymore.
760 (Backslash in a test title): Put a non-whitespace character after the
761 backslash so that Bourne shells might actually see it as an escape
763 (Brackets in a test title,
764 Pound in a test title,
765 Comma in a test title,

769 (Macro with backquote in a test title,
770 Macro with double-quote in a test title,
771 Macro with backslash in a test title): New tests expected to fail.
772 * tests/torture.at (#define header templates): M4-quote this title in
773 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
774 The visible effect was a stray [] in the testsuite output.
776 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
778 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
779 `trap ... 0' inside a function, for AIX sh.
781 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
783 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
784 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
785 5363) simply issues a warning when dividing by zero at compile
786 time. Problem reported by Elias Pipping.
788 2006-10-26 Eric Blake <ebb9@byu.net>
791 * doc/autoconf.texi (Evaluation Macros): Improve the example to
792 show effect on macros that expand with commas.

819 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
820 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
821 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
822 reported by Nelson H. F. Beebe for Coreutils 6.4.
824 * tests/tools.at (autoconf --trace: user macros): Remove test
825 for tracing multiline macros, since m4 1.4.7a uses a different
826 way to number lines. Problem reported by Ralf Wildenhues.
828 2006-10-24 Stepan Kasal <kasal@ucw.cz>
830 * bin/autom4te.in (handle_m4): Do not redirect stdin to
831 /dev/null since the heuristics for interactive behaviour was

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

902 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
904 (Imported from Automake.)
905 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
906 which incorrectly sets the mode of an existing destination
907 directory. In some cases the unpatched install-sh could do the
908 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
909 system. We hope this is rare in practice, but it's clearly worth
910 fixing. Problem reported by Alex Unleashed in
911 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
912 Also, don't bother to check for -m bugs unless we're using -m;

984 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
985 the NonStop platform.
986 * doc/autoconf.texi (Posix Variants): Likewise.
987 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
989 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
990 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
991 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
992 Use a better substitute, by inspecting the output of "ls"
993 rather than just using ":".
994 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
995 rather than AS_EXECUTABLE_P, since we needn't worry about
996 non-regular files here.
998 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
999 due to configuration hassles with this. See Tonya Underwood's report
1000 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1001 * doc/autoconf.texi (Special Shell Variables): Likewise.
1003 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1004 Stepan Kasal <kasal@ucw.cz>
1006 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
1007 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1009 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1011 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1012 initialization which is not inherited through the environment
1013 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1014 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1016 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1018 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1019 problems with mkdir -p -m.
1021 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1023 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1024 comment about ac_cpp_err; it was incorrect, and anyway
1025 ac_cpp_err is being removed below.
1026 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1027 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1028 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1030 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1031 with werror_flag and conftest.err and so forth. This is more
1032 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1033 and anyway the user shouldn't normally want to see this gorp logged.
1034 Problem reported by Ralf Wildenhues.
1035 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1036 empty, not 'no', since the rest of the code uses 'test -z'.
1038 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1040 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1041 Use a single call to AC_DO_TOKENS rather than multiple, for
1043 (_AC_LINK_IFELSE): Test that resulting file is executable.
1044 Problem reported by mwoehlke in
1045 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1047 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1048 than creating a file to use with test -x; this is much faster.
1050 2006-10-02 Bruno Haible <bruno@clisp.org>
1052 * lib/autom4te.in (Automake-preselections): Add
1053 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1055 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1057 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1058 standard error, `experr' should be used, not `expout'.
1060 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1062 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1063 fseeko testing program twice; just use the earlier result.
1064 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1065 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1066 still doesn't let the program compile.
1067 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1070 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1071 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1072 include it, without including anything else.
1073 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1075 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1077 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1079 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1080 `error.h', and include it, for a `error_at_line' prototype.
1081 Use a nonempty format string in the link test.
1082 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1083 for a declaration of wait3.
1085 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1087 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1088 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1089 can apply to constants too, and that it checks for macro defns.
1090 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1091 and simply cast the identifier to void. This handles structure
1092 values. Problem reported by Ralf Wildenhues.
1093 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1095 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1112 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1114 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): Avoid `gcc -Wall'
1115 warnings (uninitialized value).

1125 (_AC_ARG_VAR_LIBS): New macro: let LIBS be precious.
1126 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Call _AC_ARG_VAR_LIBS.
1127 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.

1148 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
1149 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed

1181 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1182 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1183 for the existence of the directory at configure-time. That's
1184 too late, anyway. Problem reported by Stefan Seefeld.
1186 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1187 7.1.4 /usr/bin/posix/sh described by Tim Rice in

1203 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1204 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1205 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now

1303 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1305 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1306 didn't work if some values were cached but not others. Test for
1307 broken lex libraries like native ia64-hp-hpux11.22; see
1308 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1309 work around the problem by preferring an empty LEXLIB to -lfl or
1310 -ll. Let the user set LEXLIB='' to indicate no library needed.
1312 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1314 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1432 longer supported by Sun.
1434 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
1436 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
1437 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1438 -Wundef -Werror". Problem reported by David Fang in
1439 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

1459 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1461 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1462 problems with arg script text that doesn't end in newline, and
1463 with '-e a...'. Problems reported by Ralf Wildenhues.
1465 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1467 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1468 check for libXt by a check for libX11.

1475 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1477 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1478 --help' should mention that `--version' outputs configuration
1479 settings. Report by Bruno Haible.
1481 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1483 Fix test suite failures reported by Pierre in
1484 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1485 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1486 the compiler created a file "b.out" when it didn't create anything
1488 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1489 Discard stderr too, when invoking the test script.

1499 less skeptical about "volatile", after discussion with
1500 Bruno Haible on bug-gnulib.
1501 (Limitations of Usual Tools): Warn about sed stripping
1502 leading white space from text. From Bruno Haible.
1504 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1506 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1507 compiler complains about it, even if things works after the
1508 complaint. Problem reported by Peter O'Gorman.
1510 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1511 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1512 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1514 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1516 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1517 after -R regardless of host. Patrick Welche reports that this
1518 fixes things on NetBSD 3.99.

1528 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1529 under AC_C_VOLATILE.
1530 (Volatile Objects): Be a little less skeptical about what
1531 "volatile" means. Derived from thoughts by Ben Pfaff in
1532 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1534 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1536 * doc/autoconf.texi: Fix some typos.
1538 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1540 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1541 more globally, since the 2006-06-30 patch didn't suffice. Problem
1542 reported by Keith Marshall. Also, don't bother with builddir2,
1543 since it shouldn't be needed any more.
1545 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1547 * doc/autoconf.texi (Generic compiler characteristics):
1548 Document AC_COMPUTE_INT. Fix wrong statements on Default

1562 * NEWS: Document previous change.
1564 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1566 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1567 Require that long long int be at least 64 bits wide. C99 requires
1568 this and enough programs depend on it so we should check for it.
1569 Bruno Haible reports in
1570 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1571 that long long int is 32 bits wide with some nonstandard compilers.
1572 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1574 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1576 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1577 to a nonexistent file, so that we don't have to worry about
1578 a local site configuration that doesn't use /usr/local.
1579 Problem reported by Keith Marshall in
1580 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1582 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1584 * doc/autoconf.texi: Be more consistent about using @acronym with
1585 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1586 quite right (it talked about "OSF/Tru64", even though the
1587 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1588 and it even mentioned "OSF 4"!) and at this point there's little
1589 reason to talk about OSF any more, since it died in 1994.
1590 (Specific Compiler Characteristics): Simplify example of
1591 negative-size array.
1592 (File Descriptors): Reorder to make the text flow better.
1593 Remove joke about "appreciate the various levels"; I didn't get it.
1594 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1595 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1596 (File Descriptors, Limitations of Usual Tools):
1597 Tone down the advice against renaming or removing open files.
1598 (Limitations of Usual Tools): Add a new section, on 'rm'.
1600 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1602 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1603 -lXt in LIBS, idea from Karsten Hopp; this was due since
1606 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1607 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1608 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1609 (which belong to Xt, not X itself). See Debian bug 327655.
1611 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1613 * configure.ac (AC_INIT): Bump to 2.60a.
1616 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1620 * configure.ac, NEWS: Update.
1622 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1624 * config/texinfo.tex: Sync from upstream.
1626 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1627 quadrigraph correctly in traces.

1633 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1635 * doc/autoconf.texi (Changed Directory Variables): New node,
1636 to document the whole `datarootdir' business a bit better.
1638 * tests/torture.at (datarootdir workaround): Extend test.
1639 Prompted by report by Alexandre Julliard.
1641 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1643 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1644 when using default mode of IBM C 6 for AIX. Problem and two-line
1645 fix reported by Larry Jones.
1647 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1649 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1650 about literal '${datarootdir}' if a definition is found in the
1653 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1655 * NEWS: Use "M4" rather than "m4" when appropriate.
1656 Problem reported by Eric Blake.
1657 * doc/autoconf.texi: Likewise.
1658 Use @acronym around BSD, GCC, and GNU when appropriate.
1659 (Why GNU M4): Renamed from "Why GNU m4".
1660 (Redefined M4 Macros): Mention that Posix
1661 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1662 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1665 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1667 * bin/autom4te.in (handle_output): Do not forbid the empty
1669 * tests/tools.at (autoconf: the empty token): New test.
1671 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1673 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1674 calls, so that we do not care whether they are LIFO or FIFO;
1675 in the m4_wrap, do not check which diversion is the topmost
1676 one, just check that the stack is balanced at the end.
1677 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1678 base diversion forever--pop the previous diversion before
1679 opening the new one; consequently, remove the m4_wrap call.
1680 * lib/autotest/general.m4 (AT_INIT): Likewise.
1681 * tests/m4sugar.at: Do not use
1682 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1684 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1685 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1687 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1688 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1689 Rework example of m4wrap token-pasting trouble so that it doesn't
1690 care whether it's LIFO or FIFO.
1691 Fix some "contrary to"s that are awkward in English.
1693 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1695 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1696 to `yes' instead of `int$1_t' if the type is found, for more
1697 consistent configure output (where $1 is the number of bits).
1698 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1699 Suggested by Bruno Haible.
1701 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1702 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1703 with system headers. Report by Bruno Haible.
1705 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1707 * config/config.guess, config/config.sub: Sync from upstream.
1709 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1710 in order to avoid picking up an older installed frozen m4sh.m4f.
1711 Besides an outdated shell startup, this could have been created
1712 by an earlier M4 version with incompatible frozen file format.
1714 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1716 * README: Recommend m4 1.4.4 instead of 1.4.3..
1717 * doc/autoconf.texi: Likewise.
1718 (Special Chars in Names): Say that $(.FOO) is portable, as
1719 suggested by Stepan Kasal.
1720 (Installation Directory Variables, Build Directories):
1721 (Automatic Remaking, Subdirectories, Fortran Compiler):
1722 (Making testsuite Scripts, Defining Directories):
1723 Quote variable usages better.
1724 (Making testsuite Scripts): Add clean-local rule to makefile
1725 snippet, by Eric Blake.
1726 (Installation Directory Variables): Fix table item font.
1727 Reword slightly to clarify. Generalize advice about
1728 not using special characters to include all file-related
1729 vars, not just VPATH.
1730 (Special Chars in Variables): Warn about special characters in
1732 (Assignments): Clarify default-value example as suggested by
1734 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1735 (Special Shell Variables): Note leading ./ or ../, as suggested
1737 (Limitations of Builtins): Under cd, warn about CDPATH.
1738 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1741 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1743 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1744 `@var', for texi2html.
1745 (Systemology): Some more word wrapping, for DVI output.
1746 (autom4te Invocation): The short option for `--melt' is `-M',
1749 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1751 * doc/autoconf.texi: More formatting and English tweaks,
1752 many suggested by Ralf Wildenhues.
1753 Reword to avoid "@code{...}'s" and the like, since it's ugly
1754 with Emacs info mode. discontents -> woes.
1755 Put a few "will"s back. time stamp -> timestamp.
1756 side-effect -> side effect.
1758 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1760 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1761 Warn about $@ not persisting. Problem reported by Julien Danjou in
1762 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1763 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1764 Mention other special chars, too.
1766 2006-06-14 Eric Blake <ebb9@byu.net>
1768 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1770 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1772 * doc/autoconf.texi: Some systematic minor improvements, as
1773 follows. Use "makefile" when talking about makefiles
1774 generally (which might be named "makefile" or "Makefile" or even
1775 "foo.mk"), "Makefile" when talking about a specific makefile
1776 called "Makefile". This unclutters the text from weird quotes
1777 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1778 values" rather than "@var{foo}s" and similar constructs containing
1779 "}s". Use "Make rules" rather than "Makefile rules". Minor
1780 English-language improvements. Change the prefix "sub-" to "sub"
1782 Put blank lines around examples more consistently.
1783 Avoid "rather" and "very" as intensifiers.
1784 Avoid "will" as an auxiliary.
1785 (Limitations of Make): Split this node into....
1786 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1787 (Leading _ in Macro Names, Backslash-Newline-Newline):
1788 (Backslash-Newline Comments, Long Lines in Makefiles):
1789 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1790 (obj/ and Make, make -k Status, VPATH and Make):
1791 (VPATH and Double-colon, $< in Explicit Rules):
1792 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1793 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1794 New nodes, resulting from splitup of Limitations of Make.
1795 All cross-references changed. Raise the top node from
1796 a section to a chapter, and all subnodes accordingly.
1797 Redo the introductory wording to match the new organization.
1798 (Installation Directory Variables): Use an example that is
1799 closer to what Autoconf actually does. Mention that VPATH's
1800 value should not contain metacharacters or white space.
1801 (Fortran Compiler): Fix a VPATH bug in an example.
1802 (Leading _ in Macro Names): Mention that this problem is no longer
1803 of practical concern.
1804 (VPATH and Make): Reword the advice to make it clearer
1805 that Autoconf and Automake support VPATH in non-GNU make, but
1806 many packages have bugs in this area.
1807 ($< in Explicit Rules): Refer to Build Directories rather
1808 than using a (non-VPATH-safe) example.
1809 (Automatic Rule Rewriting): Mention the sort of disaster that
1810 can ensue with Solaris-style rule rewriting with VPATH.
1812 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1814 * doc/install.texi (Compilers and Options): Weaken the
1815 suggestion to use GNU make for VPATH builds.
1817 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1818 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1820 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1821 in regular expression.
1823 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1825 * doc/autoconf.texi (Installation Directory Variables):
1826 Drop extra @samp from `@table @samp' item.
1827 (Limitations of Usual Tools): Comment fix.
1828 Do not nest @samp just to point to other table items.
1829 (Writing testsuite.at) <AT_CHECK>: The second argument to
1830 `@dvar' is already @samp'ed.
1831 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1832 do not use @var in the second argument.
1834 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1836 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1837 $as_shell.exe too. Problem reported by Andreas Buening in
1838 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1840 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1842 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1843 `unused variable' compiler warning, for `-Wall -Werror'.
1844 Reported by Jaap Haitsma in
1845 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1847 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1849 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1850 case the compiler dumps core. Problem reported for
1851 OpenServer 5.0.7 by Tim Rice in
1852 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1853 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1856 2006-06-06 Tim Rice <tim@multitalents.net>.
1858 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1859 "ERROR" only shows up in "make check" output if there is an

1864 * tests/tools.at (automatically allowed tokens): Fix typo.
1866 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1868 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1870 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1

1883 * config/texinfo.tex: Sync from upstream.
1885 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1886 seen, invoke libtoolize with `--ltdl' argument.
1887 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1889 Suggested by Eric Blake.
1891 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1893 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

1909 * tests/m4sugar.at: Check m4_require's error message.
1910 * tests/base.at: Check AC_REQUIRE's error message.
1911 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1913 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1915 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1916 `expout' as the last parameter.
1917 * tests/tools.at: Adapt to the above change.
1919 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1921 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1922 information about race-free implementations of mkdir.
1924 2006-06-04 Eric Blake <ebb9@byu.net>
1926 * bin/autoreconf.in (help): Document M4 environment variable.
1927 * bin/autoconf.as (Usage): Likewise.
1928 * bin/autom4te.in (help): Likewise.
1929 * doc/autoconf.texi (autom4te Invocation): Likewise.
1931 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1933 * NEWS: GNU make now recommended for VPATH builds.
1934 Mention that some macros are now documented to be obsolescent.
1935 * doc/autoconf.texi:
1936 Prefer "current" to "modern" to describe
1937 currently-used (albeit perhaps old-fashioned) hosts.
1938 Mention which ancient features no longer need to be worried about.
1939 setgid -> set-group-ID
1940 setuid -> set-user-ID (these are the Posix terms)
1941 Fix some misuses of "only".
1942 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1943 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1944 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1945 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1946 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1947 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1948 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1949 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1950 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1951 Mention that these macros are obsolescent.
1952 (Installation Directory Variables): shall -> should
1953 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1954 Mention that it's now safe to use 3 and 4.
1955 (Limitations of Usual Tools): cp -r is now specified by Posix.
1956 Omit longwinded and obsolescent discussion of cp -f.
1957 Modernize discussion of expr, ls.
1958 (Limitations of Make): Modernize discussion of VPATH builds.
1959 Mention $? as a workaround in some cases.
1960 * doc/install.texi (Basic Installation):
1961 Mention "./configure; make; make install" first. Be more
1962 specific about why this file is generic. Remove unnecessary
1963 parens. Remove misleading "only". Remove obsolete advice
1964 about csh. Don't say "configure" takes awhile; say it
1965 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1966 and CC=c99 rather than CC=c89, as these are blessed by current
1967 Posix. Recommend GNU make if doing a VPATH build.
1969 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1971 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1972 examples involving shell prompts.
1974 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1975 and Paul Eggert <eggert@cs.ucla.edu>
1977 * doc/autoconf.texi (Here-Documents): Add details about the
1978 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1979 use "here-documents" instead of "here documents".
1981 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1983 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1985 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1987 * doc/autoconf.texi (File System Conventions): Warn about ":"
1988 anywhere in directory names.
1990 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1992 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1993 about quoting the case statement, just in case.
1994 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1995 was fixed in ksh93g; reported by Ralf Wildenhues.
1997 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1999 * doc/autoconf.texi (System Services): Do not document
2000 overriding EXEEXT via ac_cv_exeext=ext.
2001 (Particular Programs) <AC_PROG_MKDIR_P>:
2002 Document that ${MKDIR_P} understands --.
2003 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2006 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2008 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2009 argument with leading hyphen. Problem reported by Paul Eggert.
2011 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2013 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2014 about quoting ac_try: quote all of it, if any of it seems suspicious.
2015 This means we don't have to worry about ${ or sed any more.
2016 Also, double-quote the case statement, to work around misuses via
2017 underquoting as reported by Ralf Wildenhues in
2018 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2019 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2020 undocumented and dangerous macro.
2021 Problem reported by Ralf Wildenhues in
2022 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2024 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2026 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2027 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2028 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2030 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2032 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2033 since evidently some packages rely on the old, broken behavior.
2034 Problem reported by Ralf Wildenhues in
2035 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2036 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2037 pre-2006-05-26 definitions, but leave in the comments that
2038 these macros are dangerous and should not be used.
2039 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2040 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2041 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2042 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2043 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2045 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2047 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2048 the use of 'tr', since this is our only use of 'tr'.
2050 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2051 and Paul Eggert <eggert@cs.ucla.edu>
2053 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2054 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2056 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2058 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2059 the output file in the `${datarootdir}' test.
2061 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2062 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2064 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2065 mention of `datarootdir' in the input file(s), but literal
2066 `${datarootdir}' in the output file, and we haven't warned yet,
2067 then warn as well: the user may have (erroneously) used
2068 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2069 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2070 * tests/torture.at (datarootdir workaround): Extend this test.
2073 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2074 and Paul Eggert <eggert@cs.ucla.edu>
2076 * doc/autoconf.texi (autoheader Invocation): The first argument to
2077 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2078 alternatives and clear up the language a bit.
2080 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2082 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2083 ac_config_guess, ac_config_sub, ac_configure.
2084 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2085 Fix typo that prevented an unnecessary space from being removed.
2086 Problems reported by Ralf Wildenhues in:
2087 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2089 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2091 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2092 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2093 Don't use the term "thread-safe" to talk about mkdir race
2094 conditions, since the problem is more a process than a thread
2095 issue. Problem reported by Stepan Kasal in:
2096 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2097 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2098 the test for 'install' more closely. Look at MKDIR_P first.
2099 Look in the PATH, and at /opt/sfw/bin.
2100 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2101 Don't bother to try mkdir -p, since we already check mkdir --version;
2102 just look at the version number. (There's no easy way to check
2103 for race-free implementations.)
2104 * tests/tools.at (autoconf: subdirectories): Adjust to above
2105 changes, since MKDIR_P now might end in "/mkdir -p".
2107 * doc/autoconf.texi (autoheader Invocation): Mention that the
2108 first arg of AC_DEFINE_UNQUOTED must be a literal.
2109 Problem reported by Ben Pfaff in
2110 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2112 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2113 * doc/autoconf.texi (Special Chars in Variables): New section.
2114 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2115 (Installation Directory Variables): Quote $(datadir) better.
2116 (Limitations of Builtins): Describe some of eval's trickiness.
2118 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2119 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2120 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2121 in front of every arg, not just trailing args. Quote apostrophes.
2122 (_AC_EVAL_ECHO): New macro.
2123 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2124 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2126 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2127 exposed by quoting of eval argument. Put the command on line line
2129 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2130 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2131 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2132 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2133 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2134 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2135 Use eval more safely.
2136 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2137 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2139 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2140 lines, exposed by quoting of eval argument.
2142 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2143 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2145 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2146 initialization of `ac_cv_exeext', do not override it if it was
2147 already set, unless it was set to `no', for compatibility with
2148 Autoconf-2.13, and comment this.
2149 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2150 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2151 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2152 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2153 Document that this test may be overridden by setting
2156 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2158 Revert these two patches:
2160 2006-04-06 Eric Blake <ebb9@byu.net>
2161 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2162 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2165 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2166 Clean up _AC_COMPILER_EXEEXT* macros.
2167 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2168 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2169 ac_file to the name of the default output file and call
2170 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2171 initial `rm' of the candidate files...
2172 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2173 the same list in subsequent `rm' calls, and for the temporary
2174 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2175 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2176 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2177 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2178 no longer needed) by libtool. Make it a cache check.
2179 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2180 copied here by mistake.
2181 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2182 _AC_COMPILER_EXEEXT.
2183 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2184 _AC_COMPILER_OBJEXT directly.
2185 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2187 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2189 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2190 Fix description of how the buggy `sed' works.
2192 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2196 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2197 ENOLCK. Only mention `make -j' when applicable. Only raise
2198 fatal errors when `make -j' is involved. Improve error message.
2200 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2202 * doc/autoconf.texi (Here-Documents): We now know more about
2203 the variable expansion in here documents bug.
2204 Thanks to Tim Rice and Stepan Kasal.
2206 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2207 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2209 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2211 * tests/autotest.at (Multiline command from M4 expansion):
2212 No failure to be expected if the shell quotes newlines in
2213 commands in the `set -x' output. Report by Tim Rice.
2216 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2218 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2219 expansion in the here-documents used by config.status, as that
2220 runs afoul of the Korn shell version M-12/28/93d bug described in
2221 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2222 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2223 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2225 2006-05-23 Jim Meyering <jim@meyering.net>
2227 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2228 Fix typo introduced with 2006-04-02 change. It reversed the sense
2231 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2233 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2234 ac_dB slightly, to save bytes in the script.
2235 Max out at 50 lines, rather than 96; this is more likely
2236 (though not guaranteed) to avoid obscure 'sed' failures.
2238 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2240 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2241 `tr -d -' as bad option argument. Work around this by deleting
2242 an unrelated character.
2243 Report by Tim Rice <tim@multitalents.net>.
2245 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2246 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2247 Stepan Kasal <kasal@ucw.cz>
2249 * doc/autoconf.texi (Particular Programs): Do not promise that
2250 we always prefer the GNU version of the program, and that we
2251 search according to PATH; both rules can have exceptions.
2252 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2253 AC_PROG_SED. Move descriptions of limitations
2254 to the Limitations of Usual Tools section.
2255 (Limitations of Usual Tools) <sed>: Mention script length
2256 limitations with Solaris /usr/ucb/sed.
2257 <grep>: Fix wording for empty alternative. Mention that -c and
2258 -l should not be combined, and that -E and -F should not be
2261 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2262 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2264 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2265 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2267 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2269 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2270 AC_DEFINE is now passed to m4_pattern_allow.
2271 * NEWS: Mention that; likewise for AC_SUBST.
2272 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2273 the parameter to m4_pattern_allow.
2274 * tests/tools.at: Add a check for that.
2276 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2278 * lib/autoconf/status.m4: Fix typos.
2280 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2282 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2283 only the files that this macro generates.
2285 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2287 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2288 the HP-UX sed limitation of 99 commands, labels do not count.
2289 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2291 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2293 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2295 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2296 Import the following fix from coreutils:
2298 2006-01-13 Jim Meyering <jim@meyering.net>
2300 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2301 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2302 not double-quote uses of that variable, to accommodate the rare
2303 case in which getmntent is available in none of the libraries
2304 checked. This happens at least on FreeBSD 5.0.
2306 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2308 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2309 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2310 some other programs unwisely rely on these undocumented vars.
2311 But put in warning comments about them.
2312 Problem reported by Ralf Wildenhues in
2313 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2314 * NEWS: Document that these variables are intended to go away.
2316 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2318 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2319 and set the language to C++ (analogous to the equivalent Fortran
2322 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2323 * doc/autoconf.texi (C++ Compiler): Document it.
2324 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2327 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2329 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2330 that caused config.status to generate 100-command sed scripts; the
2331 portable limit is 99.
2333 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2335 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2336 variable `ac_d' instead of `d' to avoid infringing namespace.
2337 Report by Ralf Menzel.
2339 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2341 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2342 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2343 * tests/tools.at (autoconf: subdirectories): New test, taken from
2344 the corresponding problem report by Ralf Wildenhues in:
2345 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2347 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2348 Quote some uses of shell variables if they might suffer unexpected
2349 globbing. This doesn't fix all instances of quoting problems that
2350 I found, just the easy ones that look safe.
2351 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2352 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2353 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2354 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2355 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

2357 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2359 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2360 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2362 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2364 * bin/autoreconf.in ($help): Reword according to the manual.
2365 Suggested by Olly Betts.
2367 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2368 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2370 * bin/autoreconf.in: Pass the directory argument to
2371 `require_configure_ac'. Fix comment.
2372 * tests/torture.at (Configuring subdirectories): Expose this.
2373 Reported by Olly Betts.
2375 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2377 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2378 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2379 Automake as follows:
2381 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2382 `$configure_in' instead of `configure.in', to preserve
2383 directory component.
2385 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2387 * config/config.guess, config/config.sub, config/texinfo.tex,
2388 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2390 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2392 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2393 test for C99 conformance; (bool) 0.5 is an integer constant
2394 expression, but (bool) -0.5 is not. Problem reported by Fedor
2395 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2397 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2399 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2400 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2401 Warn about obsolete install-sh files. Remove stray sentence
2402 fragment and fix cross reference.
2403 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2404 install -d; this undoes the 2006-05-10 change.
2405 (MKDIR_P): Mark with AN_MAKEVAR.
2406 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2407 that we don't require $INSTALL to be thread-safe. Move comments
2408 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2409 of AC_PROG_INSTALL. Output a message saying that we're checking
2410 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2411 MKDIR_P instead of AC_SUBST.
2412 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2413 Special magic for MKDIR_P, too.
2414 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2416 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2418 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2420 Sync from Automake, as follows:
2422 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2423 * config/install-sh: Initialize IFS, so field splitting isn't
2425 * config/mkinstalldirs: Likewise.
2426 * config/missing: Remove superfluous quotes. Replace all uses of
2427 `[' by `test', for consistency, and for..
2428 * config/missing (sed_minuso, sed_output): New variables.
2429 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2430 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2431 Fixes `missing' to detect `--output' for help2man. Fixes
2432 PR automake/483. Report by Dennis J. Linse.
2433 (autom4te): Document in `missing --help'.
2435 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2437 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2438 * config/install-sh: Don't use 'path' to talk about file names,
2439 as per GNU coding standards. Close a race condition reported by Ralf
2440 Wildenhues and Stepan Kasal. There is still a race condition
2441 on hosts that predate Posix 1003.1-1992, but we can't help this.
2442 Don't mishandle weird characters like space on pre-Posix hosts.
2443 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2444 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2445 AC_PROG_MKDIR_P from AS_MKDIR_P.
2446 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2447 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2448 earlier editions are not (including Automake 1.8.3).
2449 Do not suggest mkinstalldirs for thread-safety.
2450 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2451 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2452 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2453 presence of special characters and race conditions.
2454 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2455 in Autoconf's name space.
2457 2006-05-10 Bruno Haible <bruno@clisp.org>
2458 and Paul Eggert <eggert@cs.ucla.edu>
2460 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2461 from Automake with minor changes.
2462 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2464 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2466 * config/install-sh: Update to Automake CVS version, as follows:
2467 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2468 * lib/install-sh: Simplify the expr implementation of dirname.
2469 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2470 * lib/install-sh: Handle --, and diagnose unknown options.
2472 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2474 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2475 `./autom4te' to create `./testsuite', since the `all' target
2476 will ensure its presence, but `installcheck' should not create
2477 the uninstalled wrappers.
2479 * tests/torture.at (Unusual Automake input files): Skip if we
2480 detect automake < 1.8.
2482 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2484 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2485 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2486 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2489 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2491 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2492 munge (multiple) white space and other oddities.
2493 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2494 single quotes in variable assignment.
2495 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2496 and similar failures by adding multiple spaces, tabs, and other
2498 Report and different test suggested by Francesco Romani
2499 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2501 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2502 single quotes, we only need to search for single quotes; this
2503 both simplifies the search pattern, and makes us less
2504 susceptible to `echo' variations for arguments not containing
2506 (_AC_ARG_VAR_VALIDATE): Likewise.
2508 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2510 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2511 `$*' and IFS concatenation issue with traditional shells and
2512 bash-2.04. Report by Seanster@Seanster.com.
2514 2006-05-03 Bruno Haible <bruno@clisp.org>
2516 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2517 precisely which Mac OS X versions have the od problem.
2519 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2521 * doc/autoconf.texi: Use @option systematically.
2523 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2524 and Bruno Haible <bruno@clisp.org>
2526 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2528 (Integer Overflow): Mention the special case of integer division
2531 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2533 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2534 traditional shells like the Solaris one that do not use the
2535 first IFS character for assembling `$*'.
2536 Prompted by a related report from autoconf_bug@nro.ca.
2538 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2539 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2541 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2542 Mention more problems with the -e option.
2544 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2547 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2549 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2550 in URLs to improve DVI formatted output (requires texinfo 4.6).
2551 (System Services, Systemology, Shellology): Likewise.
2552 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2555 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2557 (Runtime): Fix macro argument names to match description:
2558 `action-if-found' -> `action-if-true' and similarly.
2559 (Obsolete Macros): Likewise.
2560 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2561 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2562 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2564 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2566 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2569 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2572 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2574 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2575 /bin/sh set unsorted output.

2582 (Integer Overflow, Null Pointers, Buffer Overruns):
2583 (Floating Point Portability, Exiting Portably): New sections.
2584 (Writing Test Programs): Fix some langauge. Recommend exiting
2585 with status 1, not merely nonzero. Clarify exit declaration.
2586 (Run Time): Move C exit status stuff to new Exiting Portably section.
2587 (Systemology): Mention Posix and levenez. Update v7 reference.
2588 (Portable Shell): Mention the Posix shell.
2590 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2592 * bin/autoconf.as (me): Replace by as_me.
2594 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2596 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2597 since as_me isn't set yet.
2599 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2601 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2602 a few minor bugs in this area.
2604 * doc/autoconf.texi (Programming in M4sh): Comment out the
2605 documentation of AS_BASENAME, for now.
2606 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2607 (Limitations of Builtins) <basename>: Do not refer to
2609 * bin/autoconf.as (me): Don't use AS_BASENAME.
2610 (dir): Remove the unused variable.
2611 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2612 AS_DETECT_REQUIRED. All uses changed.
2613 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.

2619 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2620 (_AS_DIRNAME_PREPARE): Likewise.
2621 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2622 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2623 (AS_DIRNAME): Use "dirname --".
2625 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2627 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2628 of "run time" and "run-time" changed to "runtime", for consistency.
2629 * lib/autoconf/fortran.m4: Likewise (in comment).

2631 * lib/autoconf/general.m4: Likewise.
2632 * lib/autoconf/headers.m4: Likewise.
2634 * doc/autoconf.texi (Run Time): Document the exit status situation
2635 with more accuracy and detail.
2637 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2639 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2640 Archive is not officially `GNU' any more. Update URL.
2641 (Defining Directories): Likewise
2642 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2644 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2646 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2647 newline from the `trap' code to finish `config.log'; the NetBSD
2648 /bin/sh resets the exit status after an empty command, as
2649 documented in doc/autoconf.texi.
2650 Reported by Dalibor Topic <robilad@kaffe.org>.
2652 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2654 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2655 Suggested by Bruno Haible.
2657 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2659 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2660 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2661 Instead, just list the shells that we know work.
2662 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2663 changed. Be more cautious about the _cv_ variable.
2664 * tests/tools.at (Syntax of the shell scripts): Check the
2665 _cv_ variable once, at first, to avoid an internal autoconf error
2666 when sh -n does not work.
2668 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2670 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2672 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2674 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2675 use ">&-" since we're only 99.999% sure that this is portable,
2676 and since the MinGW bug is fixed in a different way.
2677 * lib/autotest/general.m4 (AT_INIT): Likewise.
2679 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2681 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2682 before opening config.log, to avoid hitting a bug on MinGW.
2684 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2686 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2687 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2688 This works around a MinGW bug reported by Eric Paire.
2689 Make sure that all writes to the log file append to it,
2690 rather than possibly losing data.
2691 * lib/autotest/general.m4 (AT_INIT): Likewise.
2693 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2695 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2698 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2702 * configure.ac (AC_INIT): Bump to 2.59d.
2704 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2708 * Makefile.maint (news-date-check): Do not require a leading `*'
2709 before the release date in NEWS.
2711 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2712 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2714 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2715 the instantiated file do not contain the string 'datarootdir'
2716 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2717 @mandir@, replace the reference '${datarootdir}' by the value.
2718 * tests/torture.at (datarootdir workaround): New test.
2719 * NEWS: Advertise this temporary fixup.
2720 Based on a patch by Bruno Haible, reported and analyzed by
2721 Paul Eggert and Noah Misch.
2723 2006-04-12 Eric Blake <ebb9@byu.net>
2725 * tests/autotest.at (Debugging a failed test): Fix comment.
2727 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2729 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2730 all the changes since 2006-04-07.
2732 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2734 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2735 succeeded, but `ln -s file dir' failed, take care to remove the
2736 leftover target before the next test, to prevent its spurious
2737 failure; also make sure `ln file dir' works before selecting it.
2738 Thanks to Keith Marshall for pointing this out.
2741 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2742 assignments in `at_debug_args', so that we put them correctly
2743 in the `run' script.
2744 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2745 Reported by Eric Blake.
2747 2006-04-11 Eric Blake <ebb9@byu.net>
2749 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2750 top-level tests after micro-suite has been run. Used in...
2751 (Debugging a successful test, Debugging script and environment),
2752 (Debugging a failed test): ...these new tests. The first of these
2754 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2755 macro, split out from...
2756 (AT_INIT): ...here, so that using -d also generates a run script.
2757 Document that -d inhibits top-level logging.
2758 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2759 inhibits top-level logging; debug scripts are created.
2761 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2763 * tests/autotest.at (Empty test, Empty check): New test to check it.
2765 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2768 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2770 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2771 the files if a problem appears. Make the empty *.at files
2772 read-only, too. Proposed by Ralf Wildenhues.
2774 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2776 * config/Makefile.am: Add comment to force updated Makefile.in.
2778 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2779 space only patch to this file, this patch causes the Makefile.in
2780 files that include freeze.mk to be updated, and thus have a
2781 newer time stamp again, which in turn makes a pristine CVS
2782 checkout have correct time stamps.
2784 * Makefile.maint (cvs-sv): New macro, to be used..
2785 (config.guess-url_prefix, config.sub-url_prefix)
2786 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2787 point to CVS text checkout of Gnulib files.
2788 (copyright-check): Bump current year.
2789 (announcement): Do not hard-wire `./announce-gen'.
2790 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2792 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2794 (wget_files): Update config.guess, config.sub, texinfo.tex by
2795 `wget-update', now that their URLs work again.
2797 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2799 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2800 Problem noted by Paul D. Smith.
2802 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2804 * doc/autoconf.texi: Remove unused words from word list.

2814 with a target directory; it's internally implemented as `cp'
2815 anyway, but since Autoconf advertises the possibility to use
2816 a target directory when LN_S is `ln -s', we need to find out.
2817 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2818 analyzed by Keith Marshall <keith.marshall@total.com>.

2840 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2841 apostrophe within a single-quoted string, as this is the usual
2842 tradition and is easier to read than '"'"'. Don't rely on the
2843 shell treating "$/" like '$/'. Use a more-consistent indenting

2933 _AS_DETECT_BETTER_SHELL:
2935 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2936 skip nonexistent directories.
2937 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2938 only shell candidates which exist.
2939 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2940 * lib/autotest/general.m4 (AT_INIT): No need to give three

2964 AS_MKDIR_P exits the script on failure.
2965 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2967 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2986 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2988 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2989 whether `set' quotes correctly: redirect stderr of the tested
2990 `set', and use a subshell, for Ultrix; use `sed' instead of
2991 `grep' for zsh `set' which may write binary output; match only
2992 at the beginning of a line, to avoid false positives.
2993 In order to avoid false positives by unrelated variables with
2994 multiline content, put the dump algorithm in a subshell and
2995 unset all variables containing newlines (except some which are
2996 special to the shell). Warn about cache variables that are

3042 ac_config_<foo>s again, sometimes normalized, sometimes not.
3043 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

3045 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3046 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3047 2005-07-25 rewrite. Noticed by Noah Misch.
3049 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3050 _AC_PRESERVE_HELP_ORDER, ...

3057 for --help from Cygnus `configure.'
3059 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3111 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3112 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

3115 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3116 (exclude_list): Exclude empty macros.
3117 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

3200 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3201 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3202 ac_file to the name of the default output file and call
3203 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3204 initial `rm' of the candidate files...
3205 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3206 the same list in subsequent `rm' calls, and for the temporary

3209 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3210 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3211 no longer needed) by libtool. Make it a cache check.

3213 copied here by mistake.

3991 by the function rather than ignoring it.
3992 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3993 comparing its address. Intel's interprocedural optimization was

4029 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4031 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4032 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4033 (which belong to Xt, not X itself). See Debian bug 327655.
4034 * NEWS: Mention this.

4045 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4047 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4048 calls, so that the final expansion of this macro is shorter.
4049 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4050 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4051 the cleanup there. Use AS_VAR_* macros, to be more general.
4052 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4054 * lib/autoconf/general.m4: Use AS_IF where appropriate.

4081 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4082 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

4102 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4103 Update limitations about when to call AC_CONFIG_HEADERS.
4104 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4105 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4106 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4107 ``Configuration Actions''; fix their index entries.
4109 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4110 options correctly. Process N-M as M-N if M is smaller than N.
4111 Process ranges correctly so that N-N will run only N.
4112 Sort and uniquify the tests that will be run. If there is more
4113 than one test, reinsert the banners for the tests.

4119 before passing the macro name to AH_TEMPLATE.

4142 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4144 When building in place, set srcdir="."; suggested by Tim Van Holder.
4146 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4147 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4148 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4149 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4150 does not mean "no --srcdir option".
4152 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4166 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4168 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4169 was pushdef'ed twice while popped only once. Push it only once.
4170 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.

4184 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4186 Rewrite substantial part of lib/autoconf/status.m4.
4187 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4188 and CONFIG_COMMANDS are not processed in four separate loops.
4189 Instead, there is one main loop. This alows that the common code
4190 is expanded only once, thus config.status (and configure) is smaller.
4192 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4193 the AC_LIST_FILES and cousins macros are no longer used.
4195 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4196 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4197 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4198 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4199 contain the initialization, nor the for loop, nor the associated
4200 commands; all these go to ...
4201 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4202 _AC_OUTPUT_CONFIG_STATUS.
4203 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4204 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.

4246 parameter to AC_DIAGNOSE.
4247 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.

4250 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4252 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

4349 configure_input, top_builddir, srcdir, etc.
4350 * lib/autotest/general.m4 (AT_INIT): Likewise, for

4361 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

4414 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4415 the directory specific variables; but don't call it for configure_input.

4419 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4422 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

4442 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4443 variable into diagnostic. Make the diagnostic an error, not a warning,
4444 because we really don't support spaces and suchlike in dir names.
4445 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4446 Don't worry about backslashes in srcdir; it can't happen now.

4475 (Special Shell Variables): Fix sed code this in the example.
4476 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4477 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

4490 * doc/autoconf.texi:
4491 Don't mention Solaris versions so much, if a
4492 problem is common to all extant versions of Solaris. Say "SunOS
4493 4" instead of "SunOS" for SunOS 4.
4494 (awk): Mention more of the limitations of traditional Awk.

4537 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4538 -u, since it outputs chatter if the input files are the same.
4539 Problem reported by Ralf Menzel.
4541 2005-06-08 Derek Price <derek@ximbiot.com>
4543 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4544 renaming them since they are about to be redefined anyhow.
4546 2005-06-08 Derek Price <derek@ximbiot.com>
4548 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4549 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4550 Move m4_undefine to alphabetical order.

4555 * doc/autoconf.texi (Introduction): Likewise.
4556 Reword to avoid some formatting glitches.
4557 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

4559 Redo example output tp match current CVS snapshot.
4560 Use @example.org in email addresses when the examples
4561 might get inadvertently cut-and-pasted into user code.
4562 Remove example of autom4te usage that doesn't seem to work now.
4563 Use modern AC_INIT (except when the example is meant to be
4564 shown with Autoconf 2.13).
4565 Update ksh info for Solaris 9 and later.
4567 Modernize description of Automake versions a bit.

4578 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4579 Tru64 ksh pattern matching bug. Reported against Libtool by
4580 Albert Chin <libtool@mlists.thewrittenword.com> and
4581 Nicolas Joly <njoly@pasteur.fr>.
4583 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4585 m4_cdr of one-member list was [[]] (one-member list containing an
4586 empty string) instead of [] (an empty list. Callers were skewed to
4587 match this misbehaviour. As a consequence of this:
4588 - m4_foreach([x], [], [foo]) expanded to `foo', while
4589 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4590 This bug has been fixed:
4592 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4593 expand to an empty string; print error msg if called without
4595 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4596 misbehaviour; handle [] and [[]] correctly.

4606 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4607 swallow records with more than 99 fields.
4608 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4609 parse the long line.
4611 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4613 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4614 swallow literals longer than 399. Reported by Ralf Wildenhues.
4615 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

4620 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition

4648 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4649 now contain newlines, and substituted files must be referenced on
4650 a line alone; the sed scripts to substitute them are now very

4653 commands can be put in a sed script portably.
4654 * doc/autoconf.texi (Setting Output Variables): Document above

4666 * tests/local.at: Don't attempt to check for negated character
4667 classes in shell scripts. The test was too brittle.
4669 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4671 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4672 * doc/autoconf.texi (Limitations of Builtins): Document this
4675 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4677 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4678 common code; used in many places in the tree.
4679 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4680 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4682 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4684 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4685 messages when ac_unique_file is not found.
4686 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4687 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4688 commands, for consistency with AC_MSG_ERROR and such.
4690 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4692 * bin/Makefile.am: Merge the two rules for creating scripts.
4694 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4696 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
4697 obsolete; it was never documented.
4698 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4700 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4702 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4703 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4704 (ac_top_builddir): ... this ...
4705 (ac_top_build_prefix): ... to this; the old name is also kept, for
4706 backward compatibility.
4707 (ac_top_builddir_sub): New variable, without the trailing slash,
4709 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4710 * doc/autoconf.texi (Configuration Actions): Rename
4711 ac_top_builddir to ac_top_build_prefix.
4712 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4713 at_top_builddir to at_top_build_prefix.
4714 * lib/autotest/general.m4 (AT_INIT): Likewise.
4716 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4718 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4721 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4723 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4724 argument to m4_foreach. I guess it was necessary in the past,
4725 but I think it's a no-op now.
4727 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4729 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4730 ``cat <<_ACEOF'' commands to one.
4731 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4732 * lib/autoconf/status.m4: On various places, use expr instead of
4734 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4735 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4736 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4738 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4739 the wrong patterns between ``case'' and ``esac.'' The previous
4740 code had false positives.
4742 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4744 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4746 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

4787 2005-05-13 Stepan Kasal <kasal@ucw.cz>
4789 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4791 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4792 enough arguments, similarly as in m4_bpatsubsts.
4794 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4796 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
4799 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4801 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4802 for absolute directory names in one loop.
4803 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4804 abbreviations of --version and --debug.
4806 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4808 * doc/autoconf.texi (Autoconf Language): Be more precise about
4809 quoting rules. Problems noted by Stepan Kasal.
4810 Also, throughout this document, be more careful about white space.
4811 "blank", "white space", and "space" all have different meanings
4812 and we should be careful to say what we mean.
4814 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4816 Fix C++ related problems reported by Werner Lemberg.
4817 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4818 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4819 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4820 avoid problems with C++ and throw.
4821 * tests/compile.at: .cpp, not .cc.
4823 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4825 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4827 * doc/autoconf.texi (Generic Functions): Typos.
4829 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4831 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4832 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4833 set by latest automake.
4835 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4837 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4838 outputs 0 on GNU/Linux these days.
4840 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4842 * doc/autoconf.texi (Autoconf Language): Add more description
4843 about quoting heuristics.
4844 (Limitations of Builtins): Describe "set -" problems.
4846 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4848 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4851 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4852 by AC_DEFINE; it was a mistake.
4853 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4855 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4857 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4859 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4861 * doc/autoconf.texi (External Software): Quadrigraphs are not
4862 processed correctly in AS_HELP_STRING; avoid this in the examples.
4863 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4864 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4865 comment and reduce m4_default([foo], []) to [foo].
4866 (m4_strip): Update the explanation.
4868 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4870 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4871 Remove core.conftest.* too; it's generated by Tru64 5.1.
4872 Problem reported by Jennis Pruett.
4873 * lib/autoconf/functions.m4
4874 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4875 Don't bother to remove core files; AC_RUN_IFELSE should do that
4878 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4880 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4882 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4884 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
4885 Report from Horst Wente.
4887 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4889 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4892 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4894 * doc/autoconf.texi (External Software, Package Options): Add
4895 examples showing how to implement --with-* and --enable-* options.
4897 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4899 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4900 as well as configure.in. Problem reported by Gregorio Guidi.
4902 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4904 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4905 pattern for alloca snippet.
4907 2005-04-04 Stepan Kasal <kasal@ucw.cz>
4909 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

4915 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4917 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4918 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4920 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4922 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4923 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4924 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4925 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4926 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4928 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4930 * NEWS: The configure command now warns you if you attempt to use
4931 a directory whose name contains a special character like space,
4933 * doc/autoconf.texi (Installation Directory Variables): Allow
4934 "," in file names. Do not use \@; it's not a portable regexp.
4935 * bin/Makefile.am (edit): Likewise.
4936 * lib/Makefile.am (edit): Likewise.
4937 * tests/Makefile.am (edit): Likewise.
4938 * tests/semantics.at: Likewise.
4939 * tests/torture.at: Likewise.
4940 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4941 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4942 * doc/autoconf.texi (File System Conventions): Warn about
4943 unportable file names.
4944 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4946 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4947 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4948 ac_pwd, and quote srcdir.
4949 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4951 * doc/autoconf.texi: Fix some systematic formatting problems.
4952 ".)" needs a following @: if not at the end of a sentence, and
4953 similarly for "!)". "etc." should be preceded by a comma.
4954 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4956 2005-03-22 Bruno Haible <bruno@clisp.org>
4958 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4959 argument is often called 'build-aux'.
4961 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4963 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4964 macro AC_TRY_LINK is obsolete.
4965 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4968 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4970 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4971 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4972 from a Common Lisp's `cl'.
4973 (AC_PROG_CXX): Behave according to the documentation: don't
4974 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4975 make the variable CCC precious; use `cl.exe', not `cl'.
4977 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4978 Alexandre Duret-Lutz <adl@gnu.org>
4980 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4981 /dev/null, as "configure" shouldn't read stdin, and this insulates
4982 us from problems (e.g., when testing for "cl"). Also, do this
4983 redirection before invoking "hostname" or "uname", and keep the
4984 original input stream available via...
4985 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4986 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4987 bother with "</dev/null" since it's now done at the top of
4989 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4990 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4991 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4992 * doc/autoconf.texi (File Descriptor Macros): New section.
4993 (Printing Messages): Mention it.
4994 * tests/base.at (Input/Output): New test.
4996 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4998 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4999 newline if neither \c nor -n work, as that would output two
5000 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5002 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5004 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5005 This causes that any required macros inside will get before the if.
5006 * doc/autoconf.texi (autom4te.cache): A typo.
5008 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5010 Undo previous change, except keep the change to
5011 lib/autoconf/programs.m4 that replaced grep with shell
5012 pattern-matching. This is because net-snmp configure reads stdin.
5013 Reported by Noah Misch.
5015 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5017 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5018 from /dev/null, as "configure" shouldn't read stdin, and this
5019 insulates us from problems (e.g., when testing for "cl").
5020 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5021 before invoking "hostname" or "uname".
5022 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5023 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5024 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5025 "</dev/null" since it's now done at the top of 'configure'.
5026 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5027 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5028 Also, replace grep with shell pattern-matching, to save a process.
5030 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5032 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5033 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5034 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5037 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5039 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5040 grep -q isn't portable. Improve grep -s explanation.
5041 Problem reported by Dan Manthey.
5043 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5045 * doc/autoconf.texi (Special Shell Variables): Clarify
5046 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5048 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5050 * doc/autoconf.texi: Use @acronym for DJGPP.
5051 Fix some @code's that should have been @env's, and vice versa.
5052 Sort environment variable names.
5053 Mention that shells no longer inherit IFS.
5054 Don't recommend PATH_SEPARATOR=';' so strongly.
5055 Mention that $RANDOM might expand to the empty string.
5056 "symlink" and "soft link" -> "symbolic link".
5057 Improve mktemp description (reported by Bruno Haible).
5059 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5061 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5062 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5064 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5067 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5069 * NEWS: Mention AT_COPYRIGHT.
5071 * tests/local.at (AT_CMP): Use diff directly on input files rather
5074 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5075 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5077 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5078 and Paul Eggert <eggert@cs.ucla.edu>
5080 * tests/autotest.at (Empty test suite): New test.
5081 * tests/torture.at (Substitute and define special characters)
5082 (Substitute a 2000-byte string, Define to a 2000-byte string)
5083 (Substitute a newline, Define a newline): New tests.
5085 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5087 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5088 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5089 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5090 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5091 (Standard regular expressions): New test.
5092 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5093 excess test name quoting.
5094 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5095 CPPFLAGS to `configure' instead of setting it in `configure'.
5097 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5098 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5101 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5102 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5104 * tests/local.at (AT_CMP): New macro.
5105 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5106 (AC_SAVE_STATE): Move environment grep...
5107 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5108 (AT_CONFIG_CMP): New macro.
5109 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.

5196 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5197 Update the long comment explaining it.
5199 m4_require no longer writes an ``is required by'' line to the
5200 execution stack. It contains only one bit of non-redundant
5201 information: that the macro was required, not called. And even
5202 this bit is useless in most situations: have you ever met a macro
5203 which both calls and requires the same macro?
5205 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5206 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5214 * tests/m4sugar.at (m4_require): Expect output without the
5215 ``is required by'' messages.

5253 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5254 Warn about newline stripping in `` and $(). Update Solaris
5256 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5257 X insulates us from future changes to Posix.

5311 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5312 stored in _m4_divert_diversion or _m4_divert_dump.
5313 (m4_divert_pop): When the parameter is given, compare the symbolic
5314 name with the last diversion pushed on the stack. Previously, the
5315 current diversion was compared with the numeric value of the
5316 diversion given as the parameter.
5317 (m4_require): If the macro hasn't been expanded yet, call ...
5318 (_m4_require_call): this new macro.

5578 (MAINTAINERCLEANFILES): Delete wrapper.in.
5579 (CLEANFILES): Add wrapper.in.
5580 * tests/wrapper.as: Move AS_INIT to very top, preserving copyright in
5581 the output. Replace each $as_me with a @wrap_program@.
5582 * tests/wrapper.in: Delete it; we always build it.
5584 * bin/Makefile.am (autoconf.in): Generate it in the build directory.
5585 (EXTRA_DIST): Remove autoconf.in.
5586 (CLEANFILES): Add autoconf.in.
5587 (autoconf): Find autoconf.in in the build directory.
5588 * bin/autoconf.in: Delete it; we always build it.
5590 2004-12-08 Noah Misch <noah@cs.caltech.edu>
5592 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
5593 PATH members so as to not prepend an empty element. Move a comment.
5594 * Makefile.am (SUBDIRS): Build in `tests' last.
5595 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
5597 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5599 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5600 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5601 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5602 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
5604 2004-12-07 Stepan Kasal <kasal@ucw.cz>
5606 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

5617 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
5618 out the common code to ...
5619 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
5620 value of the #define--default to 1, iff the macro was called
5621 with exactly one parameter.
5623 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5625 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5626 "char c = '\200';" rather than "char c = 0x80;" as the
5627 latter doesn't conform to the strict C standard due to
5628 overflow on signed char hosts.
5630 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5631 to -qlanglvl=ansi. We don't want to disable extensions.
5633 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5635 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

5683 * doc/autoconf.texi (Autoconf Language): Explain that
5684 ``descriptions'' may not be double quotes.
5685 (Quotation Rule Of Thumb): Likewise.
5686 (Pretty Help Strings): Likewise; remove the wrong comment;
5687 simplify the examples and improve their quoting.
5689 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5691 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5692 the $1_found variable, don't test whether the file is executable;
5693 Both things are checked ...
5694 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5695 the former ``test -f''.

5706 limitations. Reorder paragraphs for clarity.
5708 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
5710 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
5711 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
5712 variants", "Unix", and some related minor wording fixups.
5714 (Shellology, Special Shell Variables): Document that the Zsh
5715 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
5716 to Alexandre Duret-Lutz for this info.

5725 of putenv. Problem reported by Michael Wardle.
5727 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
5729 * doc/autoconf.texi (auindex): New macro.
5730 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5731 Problem reported by Stepan Kasal.
5733 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5735 Fix problems reported by Andreas Buening in:

5737 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5739 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5740 readable; it's not true in OS/2-emx.
5742 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5744 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5745 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5746 (trivial change). Problem and patch reported by Andrew Church in:
5747 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5749 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5751 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

5770 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
5774 * README: Add advice about m4 1.4.2.
5776 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5777 texinfo.tex for now (done by hand now).
5778 * Makefile.maint (wget_files, cvs_files):
5779 Remove ansi2knr.c; nobody uses it.
5780 (ansi2knr.c-url_prefix): Remove.
5781 (cvs-update): Fix test for failure. I don't know why it ever
5784 * doc/autoconf.texi: Update URLs, some of which went stale.
5785 Use @uref rather than @href.
5787 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5788 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5790 * config/config.guess, config/config.sub, config/elisp-comp,
5791 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5792 doc/fdl.texi, doc/standards.texi: Sync with master copy.

5801 tests/tools.at, tests/torture.at:
5802 Use "file name" rather than "filename" or "path",
5803 to be consistent with the terminology of the GNU coding standards.
5805 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5807 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5808 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5809 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5810 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5812 More fixes to support spaces in the name of the build directory.
5813 This isn't a complete fix but it's an improvement.
5815 * bin/autoconf.as (autom4te_options): New var.
5816 Use it instead of appending to AUTOM4TE, so that we can allow
5817 spaces in the build directory's absolute name.
5818 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5819 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5820 AT_CHECK_NOESCAPE): Likewise.
5821 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5822 main program): Likewise.
5824 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>

5832 * doc/autoconf.texi (Function Portability): Document isinf and
5833 and isnan. From a suggestion by Kevin Ryde.
5835 * lib/Autom4te/General.pm (END): Return correct exit status even
5836 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5838 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5840 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5841 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5842 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5844 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5846 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5847 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5848 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5849 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5850 * lib/autom4te.in (Automake-preselections): Preselect
5851 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5853 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5855 * lib/autom4te.in (Automake-preselections): Preselect
5856 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5859 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

5866 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5868 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5869 with pdksh, too. Problem reported by Patrick Welche via
5871 * doc/autoconf.texi (Shellology): Note that set -o posix is
5872 useful for pkdsh, too.
5874 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5876 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5877 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5878 Don't fail if ENV or BASH_ENV is readonly.
5879 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5880 etc. are read only. Problem reported by Ludovic Courtes.
5882 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5884 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5885 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5888 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5890 * doc/autoconf.texi (File System Conventions): Warn about
5891 names like "aux". Problem reported by Eric Blake.
5893 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5894 by zero instead of array size, so that we can use any arithmetic
5895 constant expression (instead of requiring an integer constant
5896 expression). This allows us to test expressions like DBL_MAX <
5897 LDBL_MAX, which didn't conform to the C standard using the old
5899 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5900 now that we can do floating-point tests at compile time.
5902 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5904 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5905 and LDBL_EPSILON, as the resulting expression isn't an
5906 integer constant expression and violates the C standard.
5907 Problem reported by Nelson H. F. Beebe. Also, check
5908 for "L" suffix, and check that long double doesn't have
5909 worse range or precision than double, that mixed-mode
5910 arithmetic doesn't generate a diagnostic, that double
5911 constants fit in long double.
5913 2004-06-03 Kevin Ryde <user42@zip.com.au>
5915 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5916 malloc(0) and realloc(NULL,size).
5918 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5921 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5923 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5924 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5927 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5929 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5930 can be rewritten using if-then-else. Suggested by Bruno Haible.
5932 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5934 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5935 Problem reported by Stepan Kasal.
5937 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5939 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5940 change). Patch reported by Ralf Wildenhues in
5941 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5943 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5944 function F exists if the compiler and linker let you compile an
5945 expression like (F != 0). Recent versions of GCC optimize away
5946 the reference to F in that case, since every function address must
5947 be nonzero, so the link succeeds even if F does not exist.
5948 Problem reported by Manu in
5949 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5951 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5952 "Unix". Many uses changed.
5953 (Limitations of Builtins): Explain better why the ! command isn't
5956 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>

5959 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5961 2004-05-19 Kevin Ryde <user42@zip.com.au>
5963 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5964 referencing AC_FUNC_STRERROR_R.
5966 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5967 note pessimistic assumption when cross compiling.
5969 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5971 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5972 (until 2004) invoked subcommands with sh -e, contra POSIX.
5973 Reported by Kevin Ryde.
5975 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5977 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5978 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5979 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5980 `test -f " /usr/bin/grep"', which _always_ failed.
5981 (AC_PROG_SED): Ditto bogus PATH fix.
5982 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5983 requires that grep correctly supports _multiple_ `-e' options, rather
5984 than stating only that grep should accept `-e'.
5986 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5988 Port to C99, which requires that 'exit' be declared.
5990 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5991 to ensure that stdlib.h is included.
5992 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5993 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5994 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5995 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5996 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5997 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5998 when using 'exit' in a test; C99 requires that 'exit' be declared.
6000 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6002 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6003 now prefers 'grep' implementations that accept -e.
6004 (Limitations of Usual Tools): Describe problems of traditional
6005 egrep and fgrep with long input lines, and of traditional grep
6007 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6008 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6009 All callers changed. Append /usr/xpg4/bin to the PATH, for
6011 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6012 the user with complaints about multiple -e options.
6013 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6014 Define it with AC_PROG_GREP.
6015 * configure.ac (AC_PROG_GREP): Add.
6016 * lib/freeze.mk (GREP): New macro.
6018 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6020 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6021 a possible candidate only after all others fail, rather than
6022 consulting it first. This improves backward compatibility by
6023 better reflecting the way shell selection occurred in previous
6024 versions of Autoconf, and should help to avoid triggering latent
6025 problems in other packages, such as the one in Automake where zsh
6026 is not handled robustly:
6027 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6028 Although it is not Autoconf's responsibility to work around
6029 problems in Automake, it nevertheless makes sense to avoid
6030 introducing unnecessary incompatibilites.
6032 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6033 Gary V. Vaughan <gary@gnu.org>
6035 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6036 how deeply nested we are when a suitable tool is found, set the
6037 ac_path_TOOL_found flag.

6049 * doc/autoconf.texi (Limitations of Make): Update documentation
6050 for `$<'. New entry `Long lines', based on a report from Simon
6051 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6052 paragraph about DJGPP, based on a mail from Richard Dawe.
6054 2004-04-20 Paul Eggert <eggert@twinsun.com>
6056 * tests/c.at (C keywords): Don't assume that GCC supports
6057 "restrict" and "inline", as sufficiently-old GCC versions do not
6058 (also, GCC configured to be in pedantic C89 mode does not).

6081 the length check on a previous tool.
6083 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6084 match expression argument, as different greps have different

6191 Problem reported by Anthony N. Frasso in
6192 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

6221 AC_SUBST provides no portable way to escape literal newlines.
6223 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6224 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6225 Darwin uses -lcrt2.o and there's little point to cataloging all
6226 the system variants. Partial fix reported by Andreas Waechter in:

6302 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6303 2003 (except 1997) to the list of copyright years. This undoes
6304 the 2003-05-22 change, which removed the older years from the list.
6305 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

6351 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6352 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6353 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6354 not <inttypes.h>. Problem reported by Tim Mooney in
6355 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6356 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6359 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6360 otherwise "make check" fails because it forbids cmp (I guess
6361 because cmp treats files as binary on DOS-like systems).

6376 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6377 -std1 disables some useful extensions on Tru64. Problem reported

6381 2004-01-14 Paul Eggert <eggert@twinsun.com>
6383 * doc/autoconf.texi (Programming in M4sh): Document that
6384 AS_MKDIR_P succeeds if the destination is a symbolic link
6385 to an existing directory.
6386 (Limitations of Usual Tools): Note that mkdir -p might not
6387 succeed on symlinks to directories.

6407 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6408 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6409 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6410 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6411 AC_COMPILE_IFELSE, since we now assume our caller invokes
6412 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6413 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6414 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6415 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6417 2004-01-07 Paul Eggert <eggert@twinsun.com>
6419 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6420 `"'...'"`, as it's confusing (and I suspect it may not work on
6421 some platforms). The code was incorrect anyway, as it assumed
6422 that \$ evaluated to itself in that context. Reported by
6423 Alexandre Duret-Lutz.
6425 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

6457 Bug reported by David Relson in
6458 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6460 * Makefile.am (autom4te-update):
6461 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

6477 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6478 -c -o might not work. From a suggestion by Kevin Ryde.
6479 (C Compiler, Generating Sources, Limitations
6480 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6481 Don't put '-o' after non-options, as POSIX doesn't allow this.

6783 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6784 -mGLOB_options_string stuff for Intel ifc, which can cause
6785 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

6808 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6809 cache variable instead of $G77 to decide whether to include -O2,
6810 since $G77 is specific to Fortran 77.
6812 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6814 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6815 free" flag. Re-order flags tested into rough order of popularity.
6817 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6819 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6820 arguments so that it can be used with syntax identical to

6894 2003-09-26 Akim Demaille <akim@epita.fr>
6896 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6897 directory for AC_CONFIG_COMMANDS' first argument exists.
6898 This makes valid the invocation of _AC_SRCPATH that follows.
6899 Reported by Eric Sunshine.
6900 * doc/autoconf.texi (Configuration Commands): Adjust.
6902 2003-09-26 Akim Demaille <akim@epita.fr>

6923 The test suite are sometimes assigning timings incorrectly.
6924 Reported by Henk Krus.
6925 Diagnosed by Nicolas Joly.
6927 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6929 Instead of making AT_help a sequence of assignments to grow

6933 (at_times_skip): Flip the meaning and rename as...

6943 * bin/Makefile.am (edit): Handle '@configure_input@'.
6944 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6945 (ifnames): chmod -w.
6946 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6947 executables, not bin/ executables! Otherwise all the magic needed
6948 to find non installed files is turned off. This caused a failure
6949 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6950 as found in its environment (sent by tests/autoreconf): pointing
6951 to bin/autom4te that could not find its files.
6952 * tests/mktests.sh: Force the replacement of generated files, for
6953 the sake of "mv" program that are interactive when overwriting a

7048 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7050 Add support for newer Fortran dialects. The F77 interface is
7051 unchanged, and continues to support Fortran 77. New FC macros
7052 correspond to all the old F77 macros, with output variables FC,
7053 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7054 available dialect, but older dialects can be specified. There are
7055 new macros AC_FC_SRCEXT to set the source extension, and
7056 AC_FC_FREEFORM to accept free-form source files.

7178 ($help): Use Autom4te::ChannelDefs::usage.
7179 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7180 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7182 2003-08-21 Akim Demaille <akim@epita.fr>
7184 First stab at preserving warnings between calls to autom4te,
7185 including when the cache is used.
7187 There are still several issues: (i) there are too many runs of m4
7188 (one for include, one for warnings, and some more), (ii) warnings
7189 spreading on several lines are not handled gracefully, (iii) the
7190 code meant to have the call stack display for errors does not work
7191 (its handling should move from m4 to autom4te).
7193 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7195 (@preselect): Add m4_warn.
7196 ($exit_status): Remove, use $exit_code.
7197 ($help): Use Autom4te::ChannelDefs::usage.
7198 (&handle_m4): No longer define the m4_warnings.
7199 At each run, extract and report the warnings.
7200 Always cache the result, including if the exit status is on
7201 failure, since if nothing changes, we should result in the same
7202 failure, hence we can use the cache.
7203 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7204 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7206 (m4_warn): Redefine as a do-nothing: it is its invocation that
7207 matters, as warnings are now reported via traces.
7208 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7209 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7210 the latter reveals calls to the former.
7214 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7216 2003-08-21 Akim Demaille <akim@epita.fr>
7218 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

7233 (&require_configure_ac): Accept an optional directory argument.
7234 ($configure_ac): Remove.
7235 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7237 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7238 * bin/autoscan.in: Adjust.
7240 2003-08-20 Akim Demaille <akim@epita.fr>
7242 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7243 Reported by Alexandre Duret-Lutz.
7245 2003-08-20 Akim Demaille <akim@epita.fr>
7247 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7248 * bin/autom4te: Adjust.
7249 In particular, be Autoconf tools are really silent when properly
7250 working, bind the verbosity of the 'note' channel to $verbose.
7251 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7252 (&xsystem, &contents): Remove, since they are exported by...
7253 * lib/Autom4te/FileUtils.pm: this.

7314 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7315 shorter column three. Add DESCRIPTION to log file content.
7317 2003-08-13 Derek Price <derek@ximbiot.com>
7319 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

7375 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7376 not all of them. This fixes 1. the fact that when testing
7377 Autoconf there are many many config.log, 2. the incorrect use of
7378 top_srcdir to find config.log.
7379 Don't mix the detailed output of failed test with the summary of
7380 failures. Rather, append detailed log afterwards.

7509 as that's closer to how it'll be used.
7511 2003-05-23 Akim Demaille <akim@epita.fr>
7513 * doc/autoconf.texi (Header Portability): ucred.h.
7516 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7518 Overhaul Autotest's logging: generate separate log files
7519 in testsuite.dir/NNN/testsuite.log, and append them to
7520 testsuite.log instead of re-running the test verbosely.
7522 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7523 file descriptor, write 0 to at_status_file instead of setting
7524 at_status=0, initialize some new variables (at_status_file,
7525 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7526 to rerun the tests, instead append the at_group_log to the
7527 at_suite_log when a test fails.
7528 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7529 with the AS_MESSAGE_LOG_FD redirected to stdout.
7530 (AT_CLEANUP): save the output status in $at_status_file
7531 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7533 (AT_CHECK): since tests are run with a redirected stdout,
7534 and used to be re-run in verbose mode, turn some $at_verbose
7535 into echo, and don't redirect the output of testing stdout
7538 * lib/autotest/autoconf.texi (testsuite Scripts): Update

7659 2003-05-06 Akim Demaille <akim@epita.fr>
7661 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7662 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7663 by aclocal.m4 is changed it might require the importing of another
7664 m4 extension file, i.e., aclocal must be run.
7666 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7667 (&parse_args): Use --force with aclocal if required and supported.

7685 (AT_CLEANUP): Add `;' to end of at_help_all.
7686 (AT_INIT): Allow --keywords to be specified more than once. When
7687 grepping $at_help_all for keywords, use the field and keyword
7688 seperators to ensure a complete keyword match. Alter at_prev handling
7689 to support the new --keywords behavior.
7691 2003-04-27 Karl Berry <karl@freefriends.org>
7693 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7694 align better with others. I also made some of the individual

7916 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7917 innocuous variant befor including <limits.h> or <assert.h>. This

7934 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7936 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7937 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7938 defined, to support freestanding compilers. This should fix the
7939 bug reported by Momchil Velkov in
7940 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7942 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7943 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7978 * Makefile.maint: Sync with Bison, i.e.:
7979 (po-check): Scan .l and .y files instead of the
7980 .c and the .h files that they generate. This fixes the bug
7981 reported by Tim Van Holder in:

8042 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8044 We _have_ to stop using the old compatibility scheme that tried to
8045 avoid useless backslashes because Libtool 1.4.3 contains a
8046 AC_DEFINE([error_t], [int],
8047 [Define to a type to use for \`error_t' if it is not
8048 otherwise available.])
8049 We _have_ to quote the single quote and backslashes with \. The
8050 old compatibility scheme saw that ` was backslashed, and therefore
8051 did not quote the single quote. Hence before this patch, Autoconf
8052 was not compatible with Libtool.

8506 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8507 aclocal invocation, as Gettext macros might not be visible to

8543 * tests/torture.at (Configuring subdirectories): Be robust to
8544 users who use config.site to require for a cache: in this case,
8545 the two last configure runs, using two different sets of
8546 arguments, trigger a legitimate error.
8548 2002-09-28 Akim Demaille <akim@epita.fr>
8550 * tests/m4sh.at (Functions Support, Functions and return Support):
8553 2002-09-28 Akim Demaille <akim@epita.fr>
8555 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
8556 autoheader are Perl programs.

8578 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8579 that were listed in the original autoscan.list.
8580 * lib/autoconf/headers.m4: Similarly with headers.
8581 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8582 (.m4.m4f): Don't pass --prepend-include, since that's done by
8583 tests/autom4te itself.
8584 * lib/autoscan/Makefile.am: Include freeze.mk.
8585 (autoscan.list): New target --this file is no longer a source.
8586 (autoscan.pre): New file.
8588 2002-09-28 Akim Demaille <akim@epita.fr>
8590 * bin/autoscan.in (@kinds): Make them singular.
8592 (&init_tables): When --debug, report the list of rules to ease
8593 tracking changes in autoscan.list.
8594 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8596 2002-09-28 Akim Demaille <akim@epita.fr>
8598 * lib/autoscan/functions, lib/autoscan/headers,
8599 * lib/autoscan/identifiers, lib/autoscan/makevars,
8600 * lib/autoscan/programs: Merge into...
8601 * lib/autoscan/autoscan.list: this.
8602 * bin/autoscan.in (&init_tables): Adjust.
8604 2002-09-28 Akim Demaille <akim@epita.fr>
8606 * lib/autoscan/functions, lib/autoscan/headers,
8607 * lib/autoscan/identifiers, lib/autoscan/makevars,
8608 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8609 `functions' line is now prefixed with `function:'.
8610 * bin/autoscan.in (&init_tables): Adjust.
8612 2002-09-28 Akim Demaille <akim@epita.fr>
8614 From now on, autoscan files must always map a macro name to a
8615 word: there is no `default' macro for autoscan.
8617 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8619 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8622 2002-09-28 Akim Demaille <akim@epita.fr>
8624 * bin/autoscan.in (%c_keywords): Remove.
8625 (&used): Keep only track of the words we might be interested in.
8626 (&output_kind): It is no longer needed to look for non active
8629 2002-09-27 Akim Demaille <akim@epita.fr>

8632 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
8633 * lib/autoscan/functions: Adjust.
8634 * doc/autoconf.texi (Particular Functions): Adjust.
8636 2002-09-27 Akim Demaille <akim@epita.fr>
8638 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8640 Thanks to Bill Moseley and Paul Eggert.
8641 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8642 the tmpdir must be created.
8643 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8644 dir be in the build tree, instead of $TMPDIR.
8646 2002-09-27 Akim Demaille <akim@epita.fr>
8648 * bin/autoscan.in: Improve the comments.
8649 (&parse_args): Drop obsolete undocumented options.
8650 (&output_kind): Output warnings.
8651 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8652 (getwd): Trigger a warning.
8654 2002-09-26 Akim Demaille <akim@epita.fr>
8656 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8657 Reported by Ralf Corsepius.
8658 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8660 2002-09-26 Akim Demaille <akim@epita.fr>
8662 Single suffix rules and seperated dependencies are not portable.
8664 * doc/autoconf.texi (Installation Directory Variables): Update.
8665 (Limitations of Make): Some about `Single Suffix Rules and
8666 Separated Dependencies'.
8667 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8668 (ifnames, autoscan, autom4te): Un-factor into several rules.
8670 2002-09-25 Paul Eggert <eggert@twinsun.com>
8672 * BUGS (Interoperability bugs): New section. Mention libtool
8673 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8675 2002-09-24 Paul Eggert <eggert@twinsun.com>
8677 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8678 make handles suffix-rules differently from GNU make.
8680 * bin/Makefile.am (SUFFIXES, .in): Remove.
8681 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8682 Move the body of the old .in rule here.
8684 2002-09-16 Akim Demaille <akim@epita.fr>
8686 i960 compilers create `b.out' files by default.
8687 Reported by Ralf Corsepius.
8689 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8690 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8692 2002-09-13 Paul Eggert <eggert@twinsun.com>
8694 * doc/autoconf.texi (Particular Headers): Remove obsolete
8695 reference to `struct timezone' in the description of
8698 2002-09-13 Akim Demaille <akim@epita.fr>
8702 * config/config.sub, config/config.guess: Update.
8703 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8704 * Makefile.am: Adjust.
8706 2002-09-13 Akim Demaille <akim@epita.fr>
8708 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8709 reading config.log when the compiler is rejected.
8710 Suggested by Guido Draheim.
8712 2002-09-13 Akim Demaille <akim@epita.fr>
8714 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8715 (chdir_init) might hang when stat'ing mounted directories.
8716 Reported by Vance Shipley.
8718 2002-09-12 Akim Demaille <akim@epita.fr>
8720 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8723 2002-09-12 Akim Demaille <akim@epita.fr>
8725 * doc/autoconf.texi (Defining Symbols): Present two different
8726 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8727 difference between 1 argument calls, and 2-3 argument calls.
8729 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8731 * doc/autoconf.texi: Review grammar and punctuation.
8733 2002-09-11 Paul Eggert <eggert@twinsun.com>
8735 * doc/autoconf.texi: Fix minor formatting, spelling, and
8737 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8738 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8741 2002-09-11 Akim Demaille <akim@epita.fr>
8743 * doc/autoconf.texi (Questions): Rename as...
8745 (Defining Directories): New.
8747 2002-09-09 Akim Demaille <akim@epita.fr>
8749 * doc/autoconf.texi (Making testsuite Scripts): Update.
8750 Suggested by Nishio Futoshi.
8752 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8754 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8755 plain `@' is wanted.
8757 2002-09-09 Akim Demaille <akim@epita.fr>
8759 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8760 `duplicates', since the algorithm was too naive and could keep
8761 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8762 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8763 Reported by Ralf Corsepius.
8764 * tests/torture.at (Configuring subdirectories): Exercise these
8767 2002-09-09 Akim Demaille <akim@epita.fr>
8769 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8770 looking for a replacement file.
8771 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8772 directory is relative.
8773 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8774 directory definition.
8775 Reported by Andreas Schwab and Jim Meyering.
8777 2002-09-06 Akim Demaille <akim@epita.fr>
8779 * doc/autoconf.texi (Setting Output Variables): Clarify what
8780 precious variables are.
8781 Suggested by Pontus Skoeld.
8783 2002-09-05 Akim Demaille <akim@epita.fr>
8785 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8786 (ifnames, autoscan, autom4te): Since we don't only depend on
8787 configure.ac variables (such as VERSION etc.), but also on prefix
8788 and so forth, depend on Makefile, not configure.ac.
8789 Reported by Alexandre Duret-Lutz.
8790 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8792 2002-09-05 Kevin Ryde <user42@zip.com.au>
8794 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8795 doesn't seem to be confined to ia64, just say "some versions".
8797 2002-09-04 Akim Demaille <akim@epita.fr>
8799 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8801 * Makefile.am (maintainer-clean-local): Remove.
8802 (MAINTAINERCLEANFILES): Remove COPYING.
8804 2002-09-03 Paul Eggert <eggert@twinsun.com>
8806 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8807 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8810 2002-09-03 Akim Demaille <akim@epita.fr>
8812 * configure.ac: Bump to 2.53d.
8813 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8814 as of today, on Automake's team suggestion.
8816 2002-09-03 Akim Demaille <akim@epita.fr>
8820 2002-09-02 Akim Demaille <akim@epita.fr>
8822 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8824 * configure.ac: Disable SITE_MACRO_DIR.
8826 2002-09-02 Jim Meyering <meyering@lucent.com>
8828 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8829 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8830 Also, tweak grammar: s/make sure to/be sure to/.
8832 2002-09-02 Paul Eggert <eggert@twinsun.com>
8834 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8835 directory names are generally preferable to physical names.
8837 2002-09-02 Akim Demaille <akim@epita.fr>
8839 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8840 Reported by Raja R. Harinath.
8841 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8842 * bin/autoupdate.in: Use error instead of die.
8844 2002-09-01 Paul Eggert <eggert@twinsun.com>
8846 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8847 ordinary shell concatenation rather than echo+tr+sed command that
8848 runs afoul of a long-line-related sed bug in Solaris 8.
8850 * bin/autoheader.in (parse_args): --warning -> --warnings.
8852 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8853 stdout, as traditional "ls" does.
8854 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8855 _AC_COMPILER_EXEEXT_O): Likewise.
8856 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8858 * bin/autoconf.as: Add --prepend-include option. This patch was
8859 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8860 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8862 * bin/autoconf.in, configure: Regenerate.
8864 * doc/autoconf.texi (Special Shell Variables): Mention
8865 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8867 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8868 MAILPATH and set PS1, PS2, PS4 to default values, to work
8869 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8870 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8871 the Autoconf documentation specifies; fall back to "unset" only if
8872 this fails. Use a shell for-loop for this rather than an m4 loop,
8873 to shorten the output script.
8875 2002-08-30 Paul Eggert <eggert@twinsun.com>
8877 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8878 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8879 for the CDPATH problem. Document PWD.
8880 (Limitations of Builtins): Document the problem that "cd $foo" and
8881 "ls $foo" may refer to different directories in shells conforming
8882 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8883 example, since the old example is now out of date.
8885 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8886 FOO" and "ls FOO" talk about different directories; this catches
8887 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8890 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8891 of rolling our own unset.
8892 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8893 in practice we needn't worry about CDPATH if unset doesn't work.
8895 * Makefile.in, aclocal.m4, bin/Makefile.in,
8896 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8897 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8898 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8899 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8900 tests/Makefile.in: Regenerate with Automake 1.6.3.
8902 * config/config.guess, config/config.sub, config/mkinstalldirs:
8905 * configure: Regenerate with self.
8907 2002-08-30 Kevin Ryde <user42@zip.com.au>
8909 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8912 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8914 * bin/autom4te.in (Request::load): Correctly test for "do" read
8917 2002-08-29 Akim Demaille <akim@epita.fr>
8919 * lib/Autom4te/General.pm (&xqx): New.
8920 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8921 hand, which is not portable.
8923 * bin/autom4te.in: Use them.
8924 Use &error instead of die.
8925 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8928 2002-08-17 Paul Eggert <eggert@twinsun.com>
8930 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8931 default list of compilers to try, since it was long ago superseded
8932 by the ksh fc builtin. Suggested by Steven G. Johnson.
8934 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8936 * doc/autoconf.texi (Invoking autom4te): End the option table,
8937 fixing a bug introduced by the previous patch.
8938 (Limitations of Make): Add a 'target lookup' subentry in the
8939 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8941 2002-07-29 Mark D. Roth <roth@feep.net>
8943 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8944 options and use $AUTOM4TE_PATH.
8945 * doc/autoconf.texi: Remove documentation of autom4te
8946 --include-envvar and --site-macro-subdir options and document
8947 use of $AUTOM4TE_PATH.
8948 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8949 arguments from each language section.
8951 2002-07-29 Paul Eggert <eggert@twinsun.com>
8953 * doc/install.texi: Include copyright symbol in copyright notice.
8955 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8957 (AM_MAKEINFOFLAGS): New macro.
8958 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8959 * Makefile.am (INSTALL): Use the new macros.
8960 Use -o rather than --output, since "missing" does not grok --output.
8962 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8964 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8965 comments do not always work. Never trust the exit status of
8968 2002-07-24 Kevin Ryde <user42@zip.com.au>
8970 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8971 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8973 2002-07-23 Paul Eggert <eggert@twinsun.com>
8975 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8976 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8977 apparently treats PATH="nonexistent" as if it contained ".".
8978 Bug reported by Stefan `Sec' Zehl.
8980 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8982 * doc/autoconf.texi (Limitations of Make): Mention the special
8983 handling of the obj/ directory by BSD make.
8985 2002-07-20 Kevin Ryde <user42@zip.com.au>
8987 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8990 2002-07-19 Akim Demaille <akim@epita.fr>
8992 * doc/autoconf.texi (Function Portability): `exit'.
8993 (Programming in M4sh): Ethymology of M4sh.

9007 2002-07-18 Akim Demaille <akim@epita.fr>
9009 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

9014 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
9016 2002-07-18 Akim Demaille <akim@epita.fr>,
9017 Alexandre Duret-Lutz <duret_g@epita.fr>
9019 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
9020 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
9022 2002-07-17 Russ Allbery <rra@stanford.edu>
9024 * doc/autoconf.texi (Initializing configure): Clarify the
9025 description of the tarname default.
9027 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>

9036 the order they are given.
9038 2002-07-17 Akim Demaille <akim@epita.fr>
9040 * tests/wrapsh.as, tests/wrappl.as: Merge into...
9041 * tests/wrapper.as: this.

9250 2002-05-16 Paul Eggert <eggert@twinsun.com>
9252 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9253 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9254 Both macros now accept an optional source-dir arg.
9255 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9257 * NEWS: Document this.
9258 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9260 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9261 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9262 not for GNU extensions; this undoes part of the 2000-11-03 change,

9271 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9272 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9273 and it causes a 'test' syntax error if it fails.
9274 Bug reported by Stephen Gildea.
9276 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9277 If prototypes are supported, use them to check this at compile-time,
9278 instead of trying to check it at run-time. If we must do a run-time
9279 check, assume that setvbuf is standard when cross-compiling, as
9280 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9281 Bug reported by Paul D. Smith.
9283 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9284 argument specifying location of getloadavg.c. This removes a
9285 FIXME. This idea was taken from Jim Meyering's implementation in
9287 * doc/autoconf.texi (Particular Functions): Document this.
9288 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9289 that's what the code does; this fixes a bug reported by

9294 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9295 autopoint instead of gettextize.
9296 ($uses_alocal): Rename as...
9297 ($uses_aclocal): this.
9298 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9299 Suggested by Bruno Haible.

9303 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9305 2002-04-29 Paul Eggert <eggert@twinsun.com>
9307 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9308 files to be 1 second older; just set them to be the same time.
9309 Also, sleep 1 second after the first aclocal, to work around
9310 problems with sub-second time stamps on the input files.
9312 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9314 * doc/autoconf.texi: Mention "set -e -x" lossage

9321 From Christian Cornelssen.
9323 2002-04-29 Akim Demaille <akim@epita.fr>
9325 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9326 of lack of $LINENO support, then the test will compare the $LINENO
9327 in testsuite vs. the lineno in the test file. This is wrong, of
9329 Be sure to protect it.
9330 Reported by Patrick Welche.
9332 2002-04-25 Akim Demaille <akim@epita.fr>
9334 * doc/autoconf.texi (Obsolete Macros): Typo.
9335 Reported by Vladimir Volovich.
9337 2002-04-25 Akim Demaille <akim@epita.fr>
9339 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9340 than some of the input files, hence, on the second run of aclocal,
9341 if some of its input are younger, make them older.
9342 Suggested by Paul Eggert.
9344 2002-04-25 Akim Demaille <akim@epita.fr>
9346 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

9352 and ac_subst_vars be sh variables containing the list of
9353 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9355 (_AC_INIT_PREPARE): Use them to log them.
9356 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9357 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9358 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9359 _AC_SUBST_FILES and _AC_SUBST_VARS.
9360 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9362 2002-04-24 Akim Demaille <akim@epita.fr>
9364 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9365 autoheader, so that automake does not complain about a missing
9366 config.h.in that was to be created.
9368 2002-04-23 Akim Demaille <akim@epita.fr>

9558 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9560 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9562 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9563 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9564 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9565 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9567 (AC_C_INLINE): Same.

9576 _AS_MKDIR_P_PREPARE.
9578 2002-03-28 Kevin Ryde <user42@zip.com.au>
9580 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9581 to avoid versions of HP C which don't allow that.
9583 2002-03-27 Paul Eggert <eggert@twinsun.com>
9585 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9586 (AS_SHELL_SANITIZE): Invoke it.
9587 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

9597 2002-03-25 Paul Eggert <eggert@twinsun.com>
9599 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9600 as POSIX requires, as it doesn't work with Zsh.
9601 * doc/autoconf.texi (Assignments): Document the problem.
9603 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9605 * doc/autoconf.texi (Limitations of Make): Mention more issue
9606 about VPATH, overriding of macros in sub-makes, and handling of
9609 2002-03-21 Paul Eggert <eggert@twinsun.com>
9611 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9612 problem with here-document buffer boundaries.
9614 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9615 when reinvoking the shell, to work around problems with installers
9616 who put strange things like "cd" commands in their environments.

9636 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

9640 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9641 (Limitations of Usual Tools): Add mkdir section.
9643 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9644 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9645 back on AS_DIRNAME to compute prefixes otherwise; this is
9646 roughly what mkinstalldirs does. That way, we need not have
9647 our own filename disassembler. The old disassembler did not
9648 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9650 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9651 Create at_test_all by a series of assignments,
9652 not by a single assignment of a long string. The latter causes ksh
9653 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9654 presumably because of a buffer overrun.
9656 2002-03-14 Paul Eggert <eggert@twinsun.com>
9658 * lib/autotest/general.m4 (at_times_skip):
9659 Renamed from at_times. Now a boolean.
9660 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9661 says 'times: not found'.

9665 * bin/autoreconf.in (&study_gettextize): New.
9666 (&autoreconf): Handle newest gettextize.

9706 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9708 2002-03-08 Akim Demaille <akim@epita.fr>
9710 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9711 aliases the actual variables, and modifications of the former
9714 2002-03-08 Akim Demaille <akim@epita.fr>
9716 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9717 because of C-c: have m4 output in tmp files, then mv them.
9719 2002-03-08 Akim Demaille <akim@epita.fr>
9721 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

9746 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9749 2002-03-04 Akim Demaille <akim@epita.fr>
9751 * doc/autoconf.texi (Transforming Names): Equality between target
9752 and host is irrelevant.
9753 (Specifying Names, Canonicalizing): Remove all references to the
9754 backward compatibility hooks. Rather, collect them all into...
9755 (Hosts and Cross-Compilation): this new section.
9756 * doc/install.texi (System Type): Ditto.
9757 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9758 that `--host' implies cross-compilation.
9760 2002-03-04 Akim Demaille <akim@epita.fr>
9762 * doc/autoconf.texi (Evaluation Macros): New.
9763 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9765 (_m4_foreach): Define the variant with immediate evaluation so
9766 that it contains exactly the items, not an expression which
9767 evaluation is the current item.
9768 (m4_re_string, m4_re_word): Don't over quote them.
9770 2002-03-04 Akim Demaille <akim@epita.fr>
9772 Instead of having stacking `shift's evaluated at the end, let
9773 `foreach' loops immediately evaluate them.
9775 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9776 $*. This is the n-th time I change my mind, but hopefully this is
9779 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9781 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9782 it was only a hack for m4_text_wrap.
9783 (m4_car2): Remove, replaced by...
9785 (_m4_foreach): Adjust.
9786 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9787 m4_bpatsubst for clarification.
9789 2002-03-04 Akim Demaille <akim@epita.fr>

9839 AC_PREFIX_PROGRAM fails with dashed program names
9841 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9842 variable when looking for the prefix program.
9843 Now it also works for shell variables.

9875 cross-compilers, too. This undoes some of the most recent change
9878 2002-02-05 Akim Demaille <akim@epita.fr>
9880 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

9906 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9907 (M4sh): Rely on M4sugar.

9945 2002-01-28 Akim Demaille <akim@epita.fr>
9947 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9948 AUTOTEST_PATH *after* it was set.
9949 Don't put `.' in the PATH: the user should be precise and `./' if
9950 needed. In addition, given that the test suite does some `cd', if
9951 `.' is in the path, the `tested programs' sections will report
9952 programs found in the test suite's directory, while during the
9953 tests (performed in their own directory), these programs are no
9954 longer visible. In other words, the results is confusing and
9956 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

10088 C/Fortran linking on HP/UX, by extracting the Fortran library
10089 search path from the LPATH line in the $F77 -v output.
10091 2001-12-12 Kevin Ryde <user42@zip.com.au>
10093 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10094 forbidden file descriptors table.
10096 2001-11-26 Akim Demaille <akim@epita.fr>
10098 * bin/autoscan.in (%c_keywords): Build it at top level.
10099 Map to 1 in order to simplify its uses.
10101 2001-11-26 Akim Demaille <akim@epita.fr>
10103 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10104 Remove $filepath, useless.
10105 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10106 variables, they are really part of the tokens.
10107 Split the input line on spaces and then look for tokens.
10108 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10109 because of `lex$U.$(OBJEXT)'.
10110 (&scan_files): Use "@list" instead of join.
10111 * doc/Makefile.am (CLEANFILES): Add *.fns.
10113 2001-11-26 Akim Demaille <akim@epita.fr>
10115 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10116 Remove, replaced by...
10117 * tests/wrappl.in: Be common for all the Perl executables.
10118 In particular autoscan and autoheader want -I.
10119 * configure.ac: Adjust.
10120 * lib/autoscan/headers: errno.h is portable.
10122 2001-11-26 Akim Demaille <akim@epita.fr>
10124 * bin/autoscan.in (used): New.
10127 2001-11-26 Akim Demaille <akim@epita.fr>
10129 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10131 (&scan_sh_file): Remove a duplicate pattern.
10132 (&check_configure_ac): Use long options.
10133 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10135 2001-11-26 Akim Demaille <akim@epita.fr>
10137 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10138 Before, having a line containing the opening of a multi line
10139 comment made the whole line be ignored.
10141 2001-11-26 Akim Demaille <akim@epita.fr>
10143 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10144 (testsuite Scripts): Be one of its subsection.
10145 (Autotest Logs): New.
10147 2001-11-26 Akim Demaille <akim@epita.fr>
10149 Test groups are now run two directories deeper.
10151 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10152 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10154 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10155 top_srcdir, builddir and top_builddir.
10156 Use `at_*dir' relatively to the directory containing the
10157 suite, use `*dir' when relatively to the current group dir.
10159 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10161 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10162 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10163 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10166 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10168 * doc/autoconf.texi (Using System Type): Add an example of `case
10169 $host' usage so people quit using `case $target' everywhere.
10171 2001-11-22 Akim Demaille <akim@epita.fr>
10173 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10174 spotted by Jim Meyering.
10176 2001-11-16 Paul Eggert <eggert@twinsun.com>
10178 This patch implements a `long double' suggestion by Oliver Kiddle.
10180 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10181 static, to catch errors if the value isn't known at compile-time
10182 and the compiler supports dynamic arrays. Change its name from
10183 `_array_' to `test_array' to avoid potential name clashes.
10184 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10185 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10186 better than double. Catch a bug in GCC 2.95.2 x86.
10187 * doc/autoconf.texi (C Compiler): Document the above.
10190 2001-11-13 Akim Demaille <akim@epita.fr>
10192 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10194 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10196 2001-11-13 Akim Demaille <akim@epita.fr>
10198 * lib/autotest/general.m4 (AT_INIT): After having run the test
10199 group, go back to the initial directory, not to at_suite_dir.
10201 2001-11-13 Akim Demaille <akim@epita.fr>
10203 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10204 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10205 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10207 (AT_CHECK_CONFIGURE): Use absolute paths.
10208 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10209 The problem is still the old one: there is no means in M4 (that I
10210 know about) to create a defining macro, because there is no means
10211 to create `$1' etc., therefore, the defining macro ``swallows''
10212 all the arguments meant to the defined macro.
10214 2001-11-13 Akim Demaille <akim@epita.fr>
10216 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10217 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10219 * tests/aclocal.m4: Remove, as it is no longer used.
10221 2001-11-13 Akim Demaille <akim@epita.fr>
10223 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10224 variable names when referring to a single test group, or to
10225 `suite' when referring to the whole test suite.
10226 `at_last_test' is removed: m4 compute at_format itself.
10227 (at_stdout, at_stder1, at_stderr): New variables.
10228 (AT_CHECK): Use them.
10230 2001-11-13 Akim Demaille <akim@epita.fr>
10232 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10234 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10235 Do it as soon as a test fails, don't wait till the end of the test
10237 Don't remove $as_me.[0-9]*, since these files no longer exist.
10239 2001-11-13 Akim Demaille <akim@epita.fr>
10241 * tests/tools.at: Use absolute paths, since we are no longer run
10244 2001-11-13 Akim Demaille <akim@epita.fr>
10246 Now that tests are running in their own private dir, there is no
10247 need to list the files to remove at the end of tests groups.
10249 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10250 (AT_data_files, at_data_files): Remove.
10251 (AT_CLEANUP, AT_DATA): Simplify.
10253 Remove the group dir if !debug && !failed.
10254 * tests/atspecific.m4: Adjust.
10256 2001-11-13 Akim Demaille <akim@epita.fr>
10258 Start a new layout for Autotest: `testsuite' creates
10259 `testsuite.dir' in which the at-check-line etc. files are to be
10260 found, and `testsuite.dir/003' where the test group 3 is run.
10262 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10263 at_check_line_file, at_format, at_test_normalized, at_group_dir
10265 Create the directories.
10266 Use absolute paths for at- files.
10267 (AT_CHECK): Adjust.
10269 2001-11-11 Michael Matz <matz@kde.org>
10271 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10273 (m4_car): Properly quote arguments.
10275 2001-11-13 Akim Demaille <akim@epita.fr>
10277 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10278 with stricter rules on LIBOBJS.
10280 2001-11-12 Paul Eggert <eggert@twinsun.com>
10282 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10283 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10286 2001-11-12 Akim Demaille <akim@epita.fr>
10288 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10290 2001-11-12 Akim Demaille <akim@epita.fr>
10292 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10293 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10294 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10295 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10296 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10297 specify to what the macro should be defined (typically to 1).
10299 2001-11-12 Akim Demaille <akim@epita.fr>
10301 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10304 2001-11-12 Akim Demaille <akim@epita.fr>
10306 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10307 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10308 definition used by Automake where LEX is +/- "${missing} lex" and
10309 `missing' itself contains variables.
10311 2001-11-12 Akim Demaille <akim@epita.fr>
10313 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10314 Now that M4sh pushes BODY, the comments were output at the end of
10317 2001-11-08 Akim Demaille <akim@epita.fr>
10319 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10320 that we can trace macros from aclocal.m4.
10321 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10322 obsoleted, and redirect to the former anyway.
10323 Reported by Ralf Corsepius.
10325 2001-11-08 Akim Demaille <akim@epita.fr>
10327 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10328 processed only if present.
10329 * tests/torture.at (Configuring subdirectories): Use autoreconf
10330 instead of successive calls to autoconf.
10331 Add a nonexistent subdirectory to exercise the patch above.
10332 Reported by Ralf Corsepius.
10334 2001-11-08 Kevin Ryde <user42@zip.com.au>
10336 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10337 doesn't accept .S files.
10339 2001-11-07 Akim Demaille <akim@epita.fr>
10341 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10342 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10343 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10344 * bin/autom4te.in (warn_forbidden): New.
10345 (handle_output): Use it.
10346 Read m4_pattern_forbid with messages.
10348 2001-11-05 Akim Demaille <akim@epita.fr>
10350 * bin/autom4te.in (--normalize): Remove.
10351 * lib/autom4te.in: Adjust.
10353 2001-11-05 Akim Demaille <akim@epita.fr>
10355 * tests/Makefile.am (testsuite): Rename this target as...
10356 ($(TESTSUITE)): this.
10359 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10361 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10362 the --prefix option, also remove it's argument.
10364 2001-11-05 Akim Demaille <akim@epita.fr>
10366 * doc/autoconf.texi (testsuite Invocation): Update.
10367 (Writing testsuite.at): Update.
10369 2001-11-03 Akim Demaille <akim@epita.fr>
10371 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10373 2001-11-03 Akim Demaille <akim@epita.fr>
10375 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10376 (&file_name_is_absolute): New, wrappers around routines from
10378 Use and export them.
10379 (&find_configure_ac): Optionally take a directory where to look at.
10380 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10382 Default @ARGV to `.', not find_configure_ac.
10383 (&autoreconf): Argument is a directory.
10384 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10385 * doc/autoconf.texi (autoreconf Invocation): Update.
10387 2001-11-03 Akim Demaille <akim@epita.fr>
10389 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10390 (@export_forward_subs): New.
10391 Add basename, dirname, and fileparse.
10393 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10394 Don't look for aclocal flags if we already know aclocal is not
10396 Move aclocal.m4t only if it exists.
10397 Reported by Ezra Peisach.
10399 2001-11-03 Akim Demaille <akim@epita.fr>
10401 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10402 passed on command line, defaulting to ./configure.ac if present.
10403 (&maybe_autoreconf, File::Find): Remove, unused.
10404 (&autoreconf): If autoconf is not used, don't try to trace.
10406 2001-11-02 Akim Demaille <akim@epita.fr>
10408 * configure.ac: Bump to 2.52g.
10410 2001-11-02 Akim Demaille <akim@epita.fr>
10414 2001-11-02 Akim Demaille <akim@epita.fr>
10416 * config/config.guess, config/config.sub, doc/standards.texi:
10417 * config/lispdir.m4: Update from masters.
10418 * configure.ac: Bump to 2.52f.
10420 2001-11-02 Akim Demaille <akim@epita.fr>
10422 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10423 Don't run aclocal when aclocal.m4 is not from aclocal.
10425 Don't run libtoolize and gettextize if --install is not given.
10427 2001-11-01 Paul Eggert <eggert@twinsun.com>
10429 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10430 be invoked before _AS_LINENO_PREPARE.
10431 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10432 than character ranges.
10434 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10435 invoking AS_BASENAME. Set the locale variables to 'C' if
10436 possible, as POSIX requires this to get the traditional
10438 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10440 2001-10-31 Paul Eggert <eggert@twinsun.com>
10442 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10443 with {}, as that triggers a bug in Bash 2.05.
10445 (_AS_LINENO_PREPARE): Use Sed rather than
10446 Awk. Fix the sed prepass to work even if there are multiple
10447 instances of $LINENO on the same line. Do not substitute for
10448 other variables like $LINENOT. Do not check file dates; such a
10449 check is unreliable on sufficiently fast machines, and removing
10450 the check makes the code simpler and more reliable. Check for
10451 output and chmod failures.
10453 * doc/autoconf.texi (Special Shell Variables): Document
10456 2001-10-31 Akim Demaille <akim@epita.fr>
10458 * tests/Makefile.am (atconfig): Remove this target, Automake
10461 2001-10-31 Akim Demaille <akim@epita.fr>
10463 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10464 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10465 provided, while it is optional.
10466 * configure.ac: Adjust.
10468 2001-10-26 Paul Eggert <eggert@twinsun.com>
10470 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10471 lib/Autom4te/Struct.pm:
10472 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10475 * doc/autoconf.texi (Special Shell Variables): Document some
10476 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10478 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10479 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10480 eval $LINENO is not portable in practice.
10482 2001-10-24 Akim Demaille <akim@epita.fr>
10484 * lib/Autom4te/General.pm (backname): New.
10486 2001-10-24 Akim Demaille <akim@epita.fr>
10488 * m4/: Remove, merged into...
10491 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10493 * doc/autoconf.texi (Shellology): Mention the problems with bash
10494 2.05's use of ANSI quoting in its `set' builtin.
10496 2001-10-22 Paul Eggert <eggert@twinsun.com>
10498 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10499 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10500 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10501 POSIX decided to standardize on the int flavor of strerror_r.
10502 Always do char* test, as there's no reason not to.
10503 Assign to a char* var, to catch strerror_r that returns int*.
10505 * doc/autoconf.texi (Particular Functions):
10506 Document the above changes. Also, document the fact that
10507 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10509 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10511 2001-10-20 Akim Demaille <akim@epita.fr>
10513 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10514 the executable was missing from the log.
10516 2001-10-20 Akim Demaille <akim@epita.fr>
10518 * lib/Autom4te/General.pm (&update_file): If destination is
10519 unchanged, remove the source.
10520 (&up_to_date_p): Don't be verbose, be debug.
10521 * bin/autoreconf.in: No longer support --m4dir.
10522 (&autoreconf): Display the full path of the configure.ac we are
10524 Trace it only once.
10525 Be sure to honor --force with gettextize.
10526 Always run aclocal.
10527 * doc/autoconf.texi: Adjust.
10529 2001-10-20 Akim Demaille <akim@epita.fr>
10531 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10533 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10534 `intl' is already present, as it refuses unless --force.
10535 (&parse_args): Use -I, --include instead of the old Autoconf
10537 ($localdir, $autoconf_dir): Remove.
10539 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10541 2001-10-19 Jens Petersen <petersen@redhat.com>
10543 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
10544 * doc/autoconf.texi (Particular Programs): Likewise.
10546 2001-10-19 Akim Demaille <akim@epita.fr>
10548 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
10549 file in @configure_input@.
10550 Don't mention `automatically' in addition to `generated'.
10551 * tests/torture.at (#define header templates): Adjust.
10553 2001-10-19 Akim Demaille <akim@epita.fr>
10555 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10556 comment, explain how to install automatic mode selection.
10559 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10561 * bin/autoreconf.in (autoreconf): Display the path to the
10562 configure.ac being studied.
10564 2001-10-18 Paul Eggert <eggert@twinsun.com>
10566 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10567 long, to work around a bug in the HP C compiler version HP92453-01
10570 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10571 (AS_BASENAME_EXPR): New macro.
10572 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10573 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10574 and fall back on 'sed' only if the other two fail. This makes
10575 AS_BASENAME act more like AS_DIRNAME.
10576 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10577 contains white space.

11041 * lib/autoconf/c.m4:
11042 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11044 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11045 Do not pass a first argument with leading '-'
11046 to expr, by parenthesizing initial integers that might be negative.
11048 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11049 now merely checks whether it is an error to pass an argument
11052 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11053 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11054 whether it is a (compile-time) error to pass an argument to
11055 getpgrp. This simpler test supports the revised documentation,
11056 and is all that AC_FUNC_GETPGRP's users really need.
11058 2001-09-18 Akim Demaille <akim@epita.fr>
11060 * doc/autoconf.texi (Limitations of Make) <$<>: New.

11070 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11072 Add test for AS_BASENAME.
11073 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11074 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11075 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11076 * tests/base.at: Fixed the expected responses. The old ones were
11078 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11079 the documentation claims it should (and how it behaved in 2.13).
11081 2001-09-18 Akim Demaille <akim@epita.fr>
11083 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11084 the AC_CONFIG_COMMANDS invocation.
11085 This also solves the name clash problems.
11086 Don't set the package's ID.
11087 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11088 No longer to be shipped.
11089 (version.in): Remove.

11091 * lib/autoconf/status.m4: Adjust.
11092 Use `m4_PACKAGE_STRING'.
11093 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11094 the only optional argument is the name of the test suite.
11095 Expect `package.m4' to define the package signature.
11096 * lib/autom4te.in (Autotest): Add `package.m4?'.
11097 * tests/Makefile.am (package.m4): New.
11098 * tests/suite.at: ifnames is a victim.
11100 2001-09-18 Akim Demaille <akim@epita.fr>
11102 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11103 AC_LIBSOURCE, AC_CONFIG_FILES.
11104 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11105 program version string doesn't match the package's.
11106 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11109 2001-09-17 Paul Eggert <eggert@twinsun.com>
11111 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11112 Allow expression to return any value that can fit into unsigned long
11113 (not int, as before). Check for output errors.
11115 2001-09-17 Bruno Haible <haible@ilog.fr>
11117 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11118 Always include <stdio.h> and <stdlib.h>. Evaluate
11119 the expression in an extra function before these includes. Call
11120 fprintf "%d" only after ensuring the argument is of type 'int'.
11121 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11123 2001-09-17 Paul Eggert <eggert@twinsun.com>
11125 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11126 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11127 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11128 when they don't exist.
11130 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11131 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11134 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11135 version with the version used by fileutils 4.1, except use
11136 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11139 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11141 2001-09-13 Akim Demaille <akim@epita.fr>

11181 * lib/autotest/general.m4 (AT_INIT): Create and remove
11182 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11183 test suites can cohabit.
11185 2001-09-13 Akim Demaille <akim@epita.fr>
11187 * tests/mktests.sh: Don't output banners for empty test files.

11242 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

11286 to avoid GCC warnings.
11289 2001-09-05 Akim Demaille <akim@epita.fr>

11293 2001-09-05 Akim Demaille <akim@epita.fr>
11295 Be ready to handle filenames as stupid as `dnl.at', for if even
11296 the maintainer is dumb enough to do that...
11298 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11299 excellence in M4 quotation: consider `__file__' is active.
11301 And BTW, when invoking m4, pass the --include in the right order:
11304 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

11332 New, extracted from main.
11333 Use IO::File wherever possible.
11334 (input.m4): Be constant, use -I instead of hard coding $tmp.

11336 Don't invoke `_au_disable', since ac was not loaded, but just

11364 2001-08-31 Akim Demaille <akim@epita.fr>
11366 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11367 (testsuite Scripts): There is no such thing as `atconfig.in'.
11368 And actually one diagram is missing: test suite runtime.
11370 2001-08-31 Akim Demaille <akim@epita.fr>
11372 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11375 2001-08-31 Akim Demaille <akim@epita.fr>
11377 * bin/autoupdate.in (@include): `installcheck' revealed the path
11378 to m4sugar was lacking!
11380 2001-08-31 Akim Demaille <akim@epita.fr>
11382 * man/Makefile.am (.x.1): We really have to pass
11383 autom4te_perllibdir.
11385 2001-08-31 Akim Demaille <akim@epita.fr>
11387 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11388 debug scripts, in particular passing explicitly listed tests to

11393 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11394 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11395 Use directly autom4te, not autoconf.

11436 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11437 Drop AC_MACRODIR dead for real.
11438 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11439 `autoheader: `config.hin' is created'.
11440 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11442 2001-08-31 Akim Demaille <akim@epita.fr>
11444 * bin/autoheader.in: Rewrite in Perl.
11445 * tests/autoheader: Adjust.
11447 2001-08-31 Akim Demaille <akim@epita.fr>
11449 * bin/autoconf.in (--include, -I): New option.
11450 Map --localdir, --autoconf-dir onto it.
11451 Forward autom4te's options instead of interpreting them.
11452 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11453 There is no such envvar since the inception of autom4te.cfg.
11454 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11455 * bin/autoupdate.in: Adjust, and perform more control.

11457 * tests/autoconf: Dittowise.
11459 2001-08-31 Akim Demaille <akim@epita.fr>

11465 (&parse_args): Adjust.
11466 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11468 2001-08-31 Akim Demaille <akim@epita.fr>

11473 installed peer executables, only PATH is allowed to resolve it.
11474 Pass `autoconf_dir' via options, not via invisible envvars.
11475 * lib/Autom4te/General.pm (&find_peer): Remove.
11476 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11477 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11478 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11479 find the executables for it.
11480 * tests/Makefile.am: Major cleanup. Too lazy to document...
11481 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11483 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11484 indeed related to running the test suite, while passing
11485 --autoconf-dir and others is related to running non installed
11486 Autoconf executables. So don't do that, leave it to...
11487 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11488 * tests/autoscan: New.
11489 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11490 refer to library files: rely on --language.
11492 2001-08-29 Akim Demaille <akim@epita.fr>
11494 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11495 s/--set/--language/.
11497 2001-08-29 Akim Demaille <akim@epita.fr>
11499 * doc/autoconf.texi: Strip the @nodes.
11500 Suggested by Paul Eggert.
11501 (Initializing configure): Typo.
11503 2001-08-29 Akim Demaille <akim@epita.fr>
11505 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.

11975 autom4te.cache (it's a directory, not a file.
11976 * Makefile.am: Ditto (but maintainer-clean-local).
11978 2001-08-15 Akim Demaille <akim@epita.fr>
11980 * bin/autom4te.in (@m4_warning): New.
11981 (&handle_m4): Use it.
11982 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11983 warnings are issued at each run.
11984 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11985 is in the src tree.
11987 2001-08-15 Akim Demaille <akim@epita.fr>

12052 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12054 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12055 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12056 * doc/autoconf.texi (C Compiler Characteristics): Update
12057 documentation for AC_C_BIGENDIAN.
12059 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12061 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12062 magic values from an object file when cross-compiling.
12063 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12065 2001-08-10 Akim Demaille <akim@epita.fr>
12067 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12069 Suggested by Russ Allbery.
12071 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12073 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12074 current $prefix to the sub-configures.
12076 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12078 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12079 extension (needed on BeOS). Reported by Guido van Rossum.
12081 2001-08-09 Akim Demaille <akim@epita.fr>
12083 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12085 2001-08-07 Akim Demaille <akim@epita.fr>
12087 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12089 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12090 No need to remove the files before and after the each test, before
12091 each test and at the end of the suite is enough.
12092 Display only the children `times', not the shell's.
12093 If the test failed or was skipped, at-times is not available.
12095 2001-08-07 Akim Demaille <akim@epita.fr>
12097 Always produce testsuite.log, including when there are no
12098 failures. This helps getting information on skipped tests, and
12099 duration of the tests. Err, implement the latter btw.
12101 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12102 Dump information on the first run of each test.
12103 (AT_CLEANUP): Create `at-times' containing the duration of the
12106 2001-08-07 Akim Demaille <akim@epita.fr>
12108 The use of `dumpstat' revealed that `len' was used although it
12109 should not. m4_text_wrap was using it, but in the Autoconf world
12110 where it is legal. Hence (i) test M4sh in its own world, not
12111 Autoconf's, and (ii), ahem, fix the bug :)
12113 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12114 does not like `' instead of [].
12115 (AT_INIT): Forbid `^_?AT_'.
12116 And don't output such tokens.
12117 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12118 `script.as', and `autom4te.cache'.
12119 Remove `empty' and `macro' which are no longer used.
12120 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12121 * tests/m4sugar.at: Use it.
12122 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12124 2001-08-07 Akim Demaille <akim@epita.fr>
12126 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12128 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12130 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12132 2001-08-04 Akim Demaille <akim@epita.fr>
12134 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12135 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12137 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12138 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12139 (AC_F77_MAIN): Likewise.
12141 2001-08-04 Akim Demaille <akim@epita.fr>
12143 Don't rely on M4sugar outputting the patterns in files, since we
12144 might process the output _without_ running m4, hence without these
12147 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12148 * bin/autom4te.in (@Request::includes): Remove, unused.
12149 (@Request::source): Rename as...
12150 (@Request::input): this.
12151 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12152 (&handle_output): Fetch the patterns from the traces.
12153 `$forbidden' and `$allowed' are constant: use m//o.
12154 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12155 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12157 2001-08-04 Akim Demaille <akim@epita.fr>
12159 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12160 autoconf', i.e., in addition to caching traces, cache the output.
12162 * bin/autom4te.in (Request::cache): Rename as...
12163 (Request::id): this.
12164 ($cache, $icache, $tcache, $ocache): New.
12165 (&handle_m4): Save M4 output in the cache instead of $tmp.
12166 (&handle_output): Adjust.
12167 (&up_to_date_p): Check that the output cache is up to date too.
12168 (top level): Run `&handle_m4' iff force or the cache is invalid.
12169 Run `&handle_output' if the output cache is more recent.
12171 2001-08-04 Akim Demaille <akim@epita.fr>
12173 * bin/autom4te.in ($force): New.
12174 (&parse_args, &print_usage): -f, --force is a new option.
12175 (&handle_output): CPP directives might have spaces after `#'.
12176 (&parse_args): The first file only can be frozen.
12178 2001-08-04 Akim Demaille <akim@epita.fr>
12180 Don't let autom4te compute the `include' traces several times:
12181 first check that the trace cache file is up to date, and then
12182 compare its timestamp with that of the output.
12184 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12185 the preamble. Don't require 5.005 as Autom4te::General does it,
12186 and better yet (use `use', not `require'!).
12187 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12188 Class::Struct as Autom4te::Struct.
12189 * lib/Autom4te/General.pm (File::stat): Use it.
12190 (&mtime): New, export it.
12191 * bin/autom4te.in: Use it.
12192 Declare `$req' is invalid if it is outdated.
12193 Don't declare it valid before saving it if something went wrong.
12195 2001-08-04 Akim Demaille <akim@epita.fr>
12197 Autom4te shall not encode Autoconf data, and preselecting traces
12198 must be proposed to the users.
12200 * bin/autom4te.in (@required_trace): Remove.
12202 (&parse_args, &print_usage): -p, --preselect is a new option.
12203 (&up_to_date_p): Adjust.

12206 2001-08-04 Akim Demaille <akim@epita.fr>
12208 * tests/tools.at (autoconf --trace: user macros): Check traces on
12209 macros invoked without arguments, and macros invoked with multiple
12212 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

12217 2001-08-03 Akim Demaille <akim@epita.fr>
12219 * bin/autoconf.in ($@): Work around the usual sh bug.
12222 2001-08-03 Akim Demaille <akim@epita.fr>
12224 Clean up the handling of the M4 builtins tracing exception.
12226 * bin/autom4te.in (Request::request): Don't complete M4 builtins

12229 (@m4_builtin): this.
12230 (%m4_builtin_alternate_name): New.
12231 (&parse_args): Complete the trace requests with alternate names.

12243 (m4_divert_pop): Dump the whole diversion stack when a diversion
12245 * bin/autom4te.in (&handle_output): Remember of the first
12246 occurrence of a possibly undefined macro, not the last.

12248 the appear in the output.

12250 * tests/tools.at (autoconf: forbidden tokens, basic)
12251 (autoconf: forbidden tokens, exceptions): No longer sort
12252 autoconf's stderr, as it is now deterministic.
12253 Check that `dnl' is caught.

12274 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12275 `END', as `Autom4te::General::END' will be triggered.
12276 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12277 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
12278 system to run `mv', `rm', and `cmp'.
