29 status of rm so we know when it failed.
30 If cleaning of test dir failed before running the test, warn.
31 Output the line separator in verbose mode before the warning
32 to make clear the warning belongs to the following test.
34 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

51 with traditional Awk and begin.
52 * tests/torture.at (Limitations of Builtins): Document the problem
53 with Bash 2.03 printf.

57 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
59 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
60 input from /dev/null in awk test, so even Solaris /usr/bin/awk
61 will not wait for input with a script containing only a BEGIN

84 * THANKS (people): Update.
86 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
88 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
90 (Shell Substitutions): Note problems with @{var:=value} etc.
91 Add a new section for problems with @{#var} etc. Problem noted
92 by Ralf Wildenhues. See:

95 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
97 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
98 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
99 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
100 substitution will still be done by the special code.
101 Report by Jim Meyering.
103 * doc/autoconf.texi (File System Conventions): Mention that
104 $PATH_SEPARATOR is for the build system only.
105 Report by Keith Marshall.
107 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
109 * doc/autoconf.texi (Setting Output Variables): Mention that
110 all non-NUL characters are ok in substituted values.
111 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
112 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
113 carriage return for $AWK, needed for BSD awk.
114 * tests/torture.at (Substitute and define special characters):
115 Test all 8 bit non-NUL characters.
116 Report against Automake by Patrick Welche.
118 2007-01-15 Stepan Kasal <kasal@ucw.cz>
120 * doc/autoconf.texi (Specifying Names): `--host' does not
121 change the build type.
123 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
125 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
126 early on the reader side, drop stderr of the input to avoid
127 `broken pipe' error output; this may happen even with shell
128 builtin `echo' of some bash versions. Reports by Ian Macdonald
129 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
131 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
133 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
134 separate items of `ac_user_opts', to avoid long lines.
135 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
137 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
139 * doc/autoconf.texi: Fix some typos.
141 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
143 Fix some wording problems noted by Paolo Bonzini in:
144 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
145 * doc/autoconf.texi (Signed Overflow Examples): Give more
146 discussion about the allow_superuser_privileges example,
147 and change it a bit to make things clearer.
148 (Optimization and Wraparound): Clarify whether the compiler
149 will generate an infinite loop for the example derived from
150 Autoconf's mktime test.
151 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
152 Also, clarify unsigned multiplication overflow.
154 2007-01-04 Eric Blake <ebb9@byu.net>
156 * bin/Makefile.am (RELEASE_YEAR): New macro.
157 (edit): Use it to supply correct copyright year to scripts.
158 * bin/autoconf.as (version): Use it.
159 * bin/autoheader.in ($version): Likewise.
160 * bin/autom4te.in ($version): Likewise.
161 * bin/autoreconf.in ($version): Likewise.
162 * bin/autoscan.in ($version): Likewise.
163 * bin/autoupdate.in ($version): Likewise.
164 * bin/ifnames.in ($version): Likewise.
166 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
168 * doc/autoconf.texi (Integer Overflow): Revised based on today's
169 feedback. The most important changes document what happens when
170 you convert an out-of-range value to a signed integer type, and
171 say that (sum < a) != (b < 0) reliably detects overflow when sum =
174 * doc/autoconf.texi (Integer Overflow): Greatly expand and
175 rewrite, taking notions from the recent discussion on the gcc and
176 autoconf mailing lists; please see
177 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
178 and follow the many links.
179 (Integer Overflow Basics, Signed Overflow Examples):
180 (Optimization and Wraparound, Signed Overflow Advice):
181 (Signed Integer Division): New sections.
183 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
185 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
186 preprocessor macro arguments in traced name.
187 * doc/autoconf.texi (Defining symbols): Document longstanding
188 support for AC_DEFINE-ing macros with arguments, and document
189 behavior when the same variable has multiple AC_DEFINEs.
190 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
191 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
192 macros directly, giving much shorter and simpler code.
194 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
196 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
197 space before "$ac_configure_args" to prevent a 'config.status
198 --recheck' failure if ac_configure_args doesn't contain a leading
199 space. This works around a problem with the XEmacs configure.ac,
200 which uses the (undocumented) ac_configure_args variable
201 inconsistently with Autoconf.
203 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
205 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
206 Include <limits.h>, and use its INT_MAX to rewrite the
207 j loop so that it does not overflow 'int'. Problem reported by
209 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
210 Play it safe by shifting left by 1 rather than multiplying by 2,
211 as GCC is less likely to optimize this away when the value
212 is signed (when it assumes overflow leads to undefined behavior).
213 Also, don't assume time_t uses two's complement.
215 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
217 * tests/torture.at (Substitute a 2000-byte string): Avoid using
218 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
219 dumps core on it. Report by Tim Rice.
221 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
223 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
224 --disable-option-checking to --help output even when
225 AC_PRESERVE_HELP_ORDER is not used.
226 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
227 --with argument, rather than argument with [-.] replaced by
229 * NEWS: Fix typo in previous change; the news was in the
232 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
234 * NEWS: Warnings are now generated by default for unknown
235 --enable-* and --with-* options.
236 * doc/autoconf.texi (Option Checking): Renamed from
237 (Configure Option Checking). Tighten up the wording a bit.
238 (External Software, Package Options): Cross-reference to Option
239 Checking, and use this to shorten our section.
240 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
241 "$x" to test "x$foo" != x.
242 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
243 Don't warn if $enable_option_checking is "no".
244 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
245 ac_unrecognized_opts to the empty string.
246 Don't echo the unrecognized opts, as this might mishandle
247 backslashes or leading -.
248 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
249 usage next to the other --disable-FEATURE options in the
252 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
254 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
255 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
256 Print warning for unrecognized --with and --enable options
257 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
258 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
259 Disable option checking when subdirs are configured.
260 (AC_OUTPUT): If warnings are enabled, print warning about
261 unrecognized --with and --enable options at the end of
262 the configure output (as well as at the beginning).
263 * doc/autoconf.texi (Option Checking): New node.
264 Document new option warning functionality.
266 2006-12-16 Eric Blake <ebb9@byu.net>
268 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
269 * NEWS: Start news for current version.
271 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
273 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
274 Define HAVE_GETMNTENT to 1, not to the empty string.
275 Problem originally reported by Jochen Friedrich in
276 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
278 This change prompted by a problem report by Andrey Simonenko in
279 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
280 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
281 object-like macros only, in the traditional portable character
283 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
284 Warn about attempts to define things that are not identifiers.
285 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
286 awful hack that AC_DEFINEd macro names containing parentheses.
288 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
290 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
291 too drastic, even if Texinfo in theory requires it for info mode.
293 (config.status Invocation): Renamed back from Recreating a
295 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
296 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
298 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
300 * NEWS: Version 2.61a.
302 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
303 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
305 * NEWS: Document changes with echo and printf, and the lack
306 of limits on the total size of multi-line values of substituted
307 variables, and the AC_FUNC_FSEEKO fix.
309 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
311 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
312 Writing configure.ac.
313 (Autoconf Input Layout): Renamed from configure.ac Layout.
314 (Recreating a Configuration): Renamed from config.status Invocation.
315 (Obsolete Recreation): Renamed from Obsolete config.status Use.
316 (acconfig Header): Renamed from acconfig.h.
317 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
318 (Writing Testsuites): Renamed from Writing testsuite.at.
319 (Autom4te Cache): Renamed from autom4te.cache.
321 * BUGS: Remove mention of VPATH problem, since it's now documented
322 not to be a bug in the Autoconf build procedure itself, but rather
323 a problem with the proprietary `make' programs.
325 * doc/autoconf.texi (Build Directories): Add a cross reference
328 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
329 * doc/standards.texi: Sync from gnulib.
331 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
332 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
333 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
334 generated automatically.
336 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
338 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
339 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
340 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
342 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
345 `CEOF$ac_eof' special marker, the awk script cannot contain a
346 line matching `^CEOF', so this is not needed any more.
347 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
348 special marker in the test.
350 2006-12-06 Stepan Kasal <kasal@ucw.cz>
352 * tests/tools.at (autom4te preselections): Use `find -newer';
353 remove one of the sleeps.
355 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
356 more readable, using ...
357 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
359 * doc/autoconf.texi (autoheader Invocation): Do not double-
360 quote the parameter of `AH_BOTTOM' in the example.
362 2006-12-05 Stepan Kasal <kasal@ucw.cz>
364 * doc/autoconf.texi (Configuration Headers): Remove the
365 example with multiple input files.
366 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
367 multiple input files.
369 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
372 creating the awk substitution script, handle one input line at a
373 time, so that the maximum length of a substituted (multi-line)
374 value is not limited by the size of the sed pattern space.
375 The trade-off is a slightly repetitive sed script.
376 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
377 can only have up to 7 characters, due to Solaris 10 /bin/sed.
378 * tests/torture.at (Substitute a 2000-byte string): Increase the
379 test with several long lines, they should not be caught by sed
382 * tests/tools.at (autom4te preselections): New test, to flag
383 entries missing from autom4te.cfg.
384 Report by David Byron <dbyron@hheld.com>.
386 * tests/torture.at (Substitute a 2000-byte string): Actually use
387 AC_PROG_AWK, so the last change works as intended.
388 (Substitute and define special characters): Likewise.
389 (Substitute a newline): Likewise.
391 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
392 instead of `awk' consistently.
393 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
394 * tests/torture.at (Torturing config.status): Test both the
395 result of AC_PROG_AWK and plain awk.
396 (Substitute a 2000-byte string): Likewise.
397 (Substitute and define special characters): Likewise.
398 (Substitute a newline): Likewise.
400 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
402 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
403 can be assigned to a function pointer. Problem reported by
404 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
405 part of a patch by Ralf Wildenhues in that same bug report.
407 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
409 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
410 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
412 2006-12-01 Eric Blake <ebb9@byu.net>
414 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
415 cross-compiling from cygwin to mingw.
416 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
417 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
418 to lib/autoconf/c.m4.
420 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
422 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
423 string for more reliable failure. Wrap the entire test that
424 causes the broken Solaris printf to dump core, in a subshell,
425 so the segmentation fault message is reliably suppressed.
426 Fix shell expansion errors by using /usr/ucb/echo always;
427 avoid an error on systems without it by another subshell.
428 Avoid m4 expansion of `$1'. Set the zeroth argument of the
429 subshell-$as_echo to `as_echo', for better error message.
431 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
433 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
434 `BASH_SOURCE' contain a newline, set them to empty, as they may
437 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
439 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
440 years and is too hard to maintain now. The last straw was
441 reported by Jerker Baeck in
442 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
443 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
444 * doc/autoconf.texi (Particular Functions): Move
445 AC_FUNC_SETVBUF_REVERSED from here...
446 (Obsolete Macros): ... to here. Say that it does nothing now.
447 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
448 Turn into (almost) a no-op.
450 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
452 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
453 These macros are obsolescent and new applications shouldn't need them.

463 * doc/autoconf.texi (Setting Output Variables): Mention that
464 @VAR1@VAR2 has unspecified behavior. Problem reported by
466 * NEWS: Mention this.
468 * Makefile.am: Put only a single '#' into the copyright notice,
469 so that it's also present in the output file. Standardize wording
470 in makefile copyright notices to match GNU coding standards.

494 Rewrite config files generation: avoid quadratic growth in
495 the number of substituted variables by using awk instead of sed
496 for the bulk of the substitutions.
497 * NEWS: Mention this.
498 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
499 forbidden in the output (and thus input) file.
500 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
501 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
502 generate just one large awk script for substitutions,
503 eliminating much of the earlier complexity, while adding some
504 new complexity. Only expand the substitution templates at
505 configure time, for smaller configure script size. If
506 _AC_SUBST_FILES are used, test 'awk' for working getline support
507 at config.status time. If absent, interpolate through the
508 shell. The awk script was written with much help
509 from Paolo Bonzini and Paul Eggert.
510 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
511 (_AC_SED_FRAG_NUM): Likewise.
512 (_AC_SUBST_CMDS): Renamed from...
513 (_AC_SED_CMDS): ...this.
514 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
515 * tests/torture.at (Substitute a 2000-byte string): Also
516 substitute a line with 1000 words, and a variable with several
518 (Substitute and define special characters): Test awk special
519 characters, and put substitution input strings `@foo@' in the
520 output, to test that no recursion happens; test several other
521 combinations from Paolo Bonzini.
523 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
525 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
526 that replaced echo with AS_ECHO where this wasn't necessary.
527 Problem reportd by Ralf Wildenhues.
528 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
529 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
530 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
532 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
534 * lib/freeze.mk (GREP): Removed, no need to initialize this.
536 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
538 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
539 that traditional Awk lacks 3-arg "split". It has it.
540 Mention that FS must be a single character, and a few other
541 99-byte limits of traditional Awk.
542 Mention that if (i in a) doesn't work with traditional Awk.
544 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
546 * tests/autotest.at (BSx641-newline in command):

548 (Newline-CODE-BS-newline in command):
549 (Single-quote-BS-newline in command):
550 (Single-quote-newline-BS-newline in command):
551 Use printf '%s\n' instead of echo, for portability to hosts
552 where echo interprets backslashes. This will break on hosts
553 that lack printf, but for now let's assume all such hosts
554 are dead (if not, we should get reports of test failures).
556 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
558 'echo' has some portability problems, when given a first argument
559 with a leading '-', or when given any argument containing '\'.
560 Avoid using 'echo' in these cases.
561 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

585 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
586 * bin/autoconf.as: Redo verbose flag implementation, as the old
587 scheme wouldn't work with AS_ECHO.
588 * lib/autotest/general.m4 (AT_INIT): Likewise.
589 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
590 Don't use ECHO_T, since ECHO_N is now reliable.
591 * lib/autotest/general.m4 (AT_INIT): Likewise.
592 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
593 rather than using a here-document to put the script into a file.
594 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
596 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
597 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
598 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
599 bug, but we might as well stop using ECHO_N and ECHO_C internally.
600 * lib/autotest/general.m4 (AT_SETUP): Likewise.
601 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
602 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
603 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
604 operand, as AS_ECHO requires. Avoid double file name expansion.
605 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
606 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
607 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
608 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
609 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
610 Double-quote strings that would otherwise contain M4 comments.
611 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
613 * configure.ac (AC_INIT): Bump to 2.61a.
616 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
620 * configure.ac (AC_INIT): Bump to 2.61.
623 * tests/autotest.at (Macro with backslash in a test title):
624 Comment out for now, as this tests neither fails nor passes
625 reliably. Problem reported by Ralf Wildenhues.
627 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
629 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
630 in previous change, which caused test failures.

634 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
635 code for --enable, --disable, --with, and --without to...

703 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
704 benefit of platforms like Solaris+GCC where it is common to have a
705 non-working g++ installation.
707 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
708 and Joel E. Denny <jdenny@ces.clemson.edu>
709 and Paul Eggert <eggert@cs.ucla.edu>

734 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
736 * tests/torture.at (Configuring subdirectories): Do not skip
737 Automake 1.10 nor future Automake 11.1 (sic).
739 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
740 and Stepan Kasal <kasal@ucw.cz>
742 Handle special characters in test case titles correctly.
743 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
745 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
746 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST

748 ./micro-suite -l and the title in micro-suite.log.
749 (Backquote in a test title,
750 Single-quote in a test title,
751 Double-quote in a test title): Don't expect failure anymore.
752 (Backslash in a test title): Put a non-whitespace character after the
753 backslash so that Bourne shells might actually see it as an escape
755 (Brackets in a test title,
756 Pound in a test title,
757 Comma in a test title,
758 Quoted Macro in a test title,

760 Macro with single-quote in a test title): New tests.
761 (Macro with backquote in a test title,
762 Macro with double-quote in a test title,
763 Macro with backslash in a test title): New tests expected to fail.
764 * tests/torture.at (#define header templates): M4-quote this title in
765 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
766 The visible effect was a stray [] in the testsuite output.
768 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
770 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
771 `trap ... 0' inside a function, for AIX sh.
773 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
775 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
776 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
777 5363) simply issues a warning when dividing by zero at compile
778 time. Problem reported by Elias Pipping.
780 2006-10-26 Eric Blake <ebb9@byu.net>
783 * doc/autoconf.texi (Evaluation Macros): Improve the example to
784 show effect on macros that expand with commas.

809 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
811 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
812 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
813 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
814 reported by Nelson H. F. Beebe for Coreutils 6.4.
816 * tests/tools.at (autoconf --trace: user macros): Remove test
817 for tracing multiline macros, since m4 1.4.7a uses a different
818 way to number lines. Problem reported by Ralf Wildenhues.
820 2006-10-24 Stepan Kasal <kasal@ucw.cz>
822 * bin/autom4te.in (handle_m4): Do not redirect stdin to
823 /dev/null since the heuristics for interactive behaviour was

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

894 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
896 (Imported from Automake.)
897 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
898 which incorrectly sets the mode of an existing destination
899 directory. In some cases the unpatched install-sh could do the
900 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
901 system. We hope this is rare in practice, but it's clearly worth
902 fixing. Problem reported by Alex Unleashed in
903 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
904 Also, don't bother to check for -m bugs unless we're using -m;

984 Use a better substitute, by inspecting the output of "ls"
985 rather than just using ":".
986 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
987 rather than AS_EXECUTABLE_P, since we needn't worry about
988 non-regular files here.
990 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
991 due to configuration hassles with this. See Tonya Underwood's report
992 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

1018 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1019 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1020 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1022 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1023 with werror_flag and conftest.err and so forth. This is more
1024 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1025 and anyway the user shouldn't normally want to see this gorp logged.
1026 Problem reported by Ralf Wildenhues.
1027 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1028 empty, not 'no', since the rest of the code uses 'test -z'.

1036 Problem reported by mwoehlke in
1037 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1039 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1040 than creating a file to use with test -x; this is much faster.
1042 2006-10-02 Bruno Haible <bruno@clisp.org>

1062 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1063 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

1299 broken lex libraries like native ia64-hp-hpux11.22; see
1300 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

1429 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1430 -Wundef -Werror". Problem reported by David Fang in
1431 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

1447 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1448 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1451 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1453 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1454 problems with arg script text that doesn't end in newline, and
1455 with '-e a...'. Problems reported by Ralf Wildenhues.
1457 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1459 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1460 check for libXt by a check for libX11.

1467 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1469 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1470 --help' should mention that `--version' outputs configuration
1471 settings. Report by Bruno Haible.
1473 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1475 Fix test suite failures reported by Pierre in
1476 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1477 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1478 the compiler created a file "b.out" when it didn't create anything
1480 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1481 Discard stderr too, when invoking the test script.

1486 in the restoring of the werror flag.
1488 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1490 * doc/autoconf.texi (Volatile Objects): Be even a little
1491 less skeptical about "volatile", after discussion with
1492 Bruno Haible on bug-gnulib.
1493 (Limitations of Usual Tools): Warn about sed stripping
1494 leading white space from text. From Bruno Haible.
1496 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1498 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1499 compiler complains about it, even if things works after the
1500 complaint. Problem reported by Peter O'Gorman.
1502 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1503 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1504 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1506 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1508 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1509 after -R regardless of host. Patrick Welche reports that this
1510 fixes things on NetBSD 3.99.

1520 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1521 under AC_C_VOLATILE.
1522 (Volatile Objects): Be a little less skeptical about what
1523 "volatile" means. Derived from thoughts by Ben Pfaff in
1524 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1526 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1528 * doc/autoconf.texi: Fix some typos.
1530 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1532 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1533 more globally, since the 2006-06-30 patch didn't suffice. Problem
1534 reported by Keith Marshall. Also, don't bother with builddir2,
1535 since it shouldn't be needed any more.
1537 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1539 * doc/autoconf.texi (Generic compiler characteristics):
1540 Document AC_COMPUTE_INT. Fix wrong statements on Default
1541 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1543 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

1554 * NEWS: Document previous change.
1556 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1558 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1559 Require that long long int be at least 64 bits wide. C99 requires
1560 this and enough programs depend on it so we should check for it.
1561 Bruno Haible reports in
1562 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1563 that long long int is 32 bits wide with some nonstandard compilers.
1564 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1566 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1568 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1569 to a nonexistent file, so that we don't have to worry about
1570 a local site configuration that doesn't use /usr/local.
1571 Problem reported by Keith Marshall in
1572 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1574 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1576 * doc/autoconf.texi: Be more consistent about using @acronym with
1577 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1578 quite right (it talked about "OSF/Tru64", even though the
1579 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1580 and it even mentioned "OSF 4"!) and at this point there's little
1581 reason to talk about OSF any more, since it died in 1994.
1582 (Specific Compiler Characteristics): Simplify example of
1583 negative-size array.
1584 (File Descriptors): Reorder to make the text flow better.
1585 Remove joke about "appreciate the various levels"; I didn't get it.
1586 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1587 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1588 (File Descriptors, Limitations of Usual Tools):
1589 Tone down the advice against renaming or removing open files.
1590 (Limitations of Usual Tools): Add a new section, on 'rm'.
1592 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1594 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1595 -lXt in LIBS, idea from Karsten Hopp; this was due since
1598 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1599 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1600 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1601 (which belong to Xt, not X itself). See Debian bug 327655.
1603 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1605 * configure.ac (AC_INIT): Bump to 2.60a.

1625 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1627 * doc/autoconf.texi (Changed Directory Variables): New node,
1628 to document the whole `datarootdir' business a bit better.
1630 * tests/torture.at (datarootdir workaround): Extend test.
1631 Prompted by report by Alexandre Julliard.
1633 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1635 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1636 when using default mode of IBM C 6 for AIX. Problem and two-line
1637 fix reported by Larry Jones.
1639 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1641 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1642 about literal '${datarootdir}' if a definition is found in the
1645 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1647 * NEWS: Use "M4" rather than "m4" when appropriate.
1648 Problem reported by Eric Blake.
1649 * doc/autoconf.texi: Likewise.
1650 Use @acronym around BSD, GCC, and GNU when appropriate.
1651 (Why GNU M4): Renamed from "Why GNU m4".
1652 (Redefined M4 Macros): Mention that Posix
1653 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1654 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1657 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1659 * bin/autom4te.in (handle_output): Do not forbid the empty
1661 * tests/tools.at (autoconf: the empty token): New test.
1663 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1665 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1666 calls, so that we do not care whether they are LIFO or FIFO;
1667 in the m4_wrap, do not check which diversion is the topmost
1668 one, just check that the stack is balanced at the end.
1669 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1670 base diversion forever--pop the previous diversion before
1671 opening the new one; consequently, remove the m4_wrap call.
1672 * lib/autotest/general.m4 (AT_INIT): Likewise.
1673 * tests/m4sugar.at: Do not use
1674 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

1677 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1679 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1680 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1681 Rework example of m4wrap token-pasting trouble so that it doesn't
1682 care whether it's LIFO or FIFO.
1683 Fix some "contrary to"s that are awkward in English.
1685 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1687 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1688 to `yes' instead of `int$1_t' if the type is found, for more
1689 consistent configure output (where $1 is the number of bits).
1690 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1691 Suggested by Bruno Haible.
1693 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1694 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1695 with system headers. Report by Bruno Haible.
1697 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1699 * config/config.guess, config/config.sub: Sync from upstream.
1701 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1702 in order to avoid picking up an older installed frozen m4sh.m4f.
1703 Besides an outdated shell startup, this could have been created
1704 by an earlier M4 version with incompatible frozen file format.
1706 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1708 * README: Recommend m4 1.4.4 instead of 1.4.3..
1709 * doc/autoconf.texi: Likewise.
1710 (Special Chars in Names): Say that $(.FOO) is portable, as
1711 suggested by Stepan Kasal.
1712 (Installation Directory Variables, Build Directories):
1713 (Automatic Remaking, Subdirectories, Fortran Compiler):
1714 (Making testsuite Scripts, Defining Directories):
1715 Quote variable usages better.
1716 (Making testsuite Scripts): Add clean-local rule to makefile
1717 snippet, by Eric Blake.
1718 (Installation Directory Variables): Fix table item font.
1719 Reword slightly to clarify. Generalize advice about
1720 not using special characters to include all file-related
1721 vars, not just VPATH.
1722 (Special Chars in Variables): Warn about special characters in
1724 (Assignments): Clarify default-value example as suggested by
1726 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1727 (Special Shell Variables): Note leading ./ or ../, as suggested
1729 (Limitations of Builtins): Under cd, warn about CDPATH.
1730 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1733 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1735 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1736 `@var', for texi2html.
1737 (Systemology): Some more word wrapping, for DVI output.
1738 (autom4te Invocation): The short option for `--melt' is `-M',
1741 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1743 * doc/autoconf.texi: More formatting and English tweaks,
1744 many suggested by Ralf Wildenhues.
1745 Reword to avoid "@code{...}'s" and the like, since it's ugly
1746 with Emacs info mode. discontents -> woes.
1747 Put a few "will"s back. time stamp -> timestamp.
1748 side-effect -> side effect.
1750 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1752 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1753 Warn about $@ not persisting. Problem reported by Julien Danjou in
1754 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1755 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1756 Mention other special chars, too.
1758 2006-06-14 Eric Blake <ebb9@byu.net>
1760 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1762 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1764 * doc/autoconf.texi: Some systematic minor improvements, as
1765 follows. Use "makefile" when talking about makefiles
1766 generally (which might be named "makefile" or "Makefile" or even
1767 "foo.mk"), "Makefile" when talking about a specific makefile
1768 called "Makefile". This unclutters the text from weird quotes
1769 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1770 values" rather than "@var{foo}s" and similar constructs containing
1771 "}s". Use "Make rules" rather than "Makefile rules". Minor
1772 English-language improvements. Change the prefix "sub-" to "sub"
1774 Put blank lines around examples more consistently.
1775 Avoid "rather" and "very" as intensifiers.
1776 Avoid "will" as an auxiliary.
1777 (Limitations of Make): Split this node into....
1778 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1779 (Leading _ in Macro Names, Backslash-Newline-Newline):
1780 (Backslash-Newline Comments, Long Lines in Makefiles):
1781 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1782 (obj/ and Make, make -k Status, VPATH and Make):
1783 (VPATH and Double-colon, $< in Explicit Rules):
1784 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1785 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1786 New nodes, resulting from splitup of Limitations of Make.
1787 All cross-references changed. Raise the top node from
1788 a section to a chapter, and all subnodes accordingly.
1789 Redo the introductory wording to match the new organization.
1790 (Installation Directory Variables): Use an example that is
1791 closer to what Autoconf actually does. Mention that VPATH's
1792 value should not contain metacharacters or white space.
1793 (Fortran Compiler): Fix a VPATH bug in an example.
1794 (Leading _ in Macro Names): Mention that this problem is no longer
1795 of practical concern.
1796 (VPATH and Make): Reword the advice to make it clearer
1797 that Autoconf and Automake support VPATH in non-GNU make, but
1798 many packages have bugs in this area.
1799 ($< in Explicit Rules): Refer to Build Directories rather
1800 than using a (non-VPATH-safe) example.
1801 (Automatic Rule Rewriting): Mention the sort of disaster that
1802 can ensue with Solaris-style rule rewriting with VPATH.
1804 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1806 * doc/install.texi (Compilers and Options): Weaken the
1807 suggestion to use GNU make for VPATH builds.
1809 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1810 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1812 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1813 in regular expression.
1815 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1817 * doc/autoconf.texi (Installation Directory Variables):
1818 Drop extra @samp from `@table @samp' item.
1819 (Limitations of Usual Tools): Comment fix.
1820 Do not nest @samp just to point to other table items.
1821 (Writing testsuite.at) <AT_CHECK>: The second argument to
1822 `@dvar' is already @samp'ed.
1823 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1824 do not use @var in the second argument.
1826 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1828 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1829 $as_shell.exe too. Problem reported by Andreas Buening in
1830 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1832 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1834 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1835 `unused variable' compiler warning, for `-Wall -Werror'.
1836 Reported by Jaap Haitsma in
1837 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1839 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1841 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1842 case the compiler dumps core. Problem reported for
1843 OpenServer 5.0.7 by Tim Rice in
1844 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1845 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1848 2006-06-06 Tim Rice <tim@multitalents.net>.
1850 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1851 "ERROR" only shows up in "make check" output if there is an

1856 * tests/tools.at (automatically allowed tokens): Fix typo.
1858 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1860 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1862 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1863 typically overflows on x86 CPUs, even though the C standard
1866 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1868 * configure.ac (AC_INIT): Bump to 2.59e.
1871 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1875 * config/texinfo.tex: Sync from upstream.
1877 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1878 seen, invoke libtoolize with `--ltdl' argument.
1879 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1881 Suggested by Eric Blake.
1883 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1885 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1886 reported by Ralf Wildenhues.

1908 `expout' as the last parameter.
1909 * tests/tools.at: Adapt to the above change.
1911 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1913 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1914 information about race-free implementations of mkdir.
1916 2006-06-04 Eric Blake <ebb9@byu.net>
1918 * bin/autoreconf.in (help): Document M4 environment variable.
1919 * bin/autoconf.as (Usage): Likewise.
1920 * bin/autom4te.in (help): Likewise.
1921 * doc/autoconf.texi (autom4te Invocation): Likewise.
1923 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1925 * NEWS: GNU make now recommended for VPATH builds.
1926 Mention that some macros are now documented to be obsolescent.
1927 * doc/autoconf.texi:
1928 Prefer "current" to "modern" to describe
1929 currently-used (albeit perhaps old-fashioned) hosts.
1930 Mention which ancient features no longer need to be worried about.
1931 setgid -> set-group-ID
1932 setuid -> set-user-ID (these are the Posix terms)
1933 Fix some misuses of "only".
1934 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1935 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1936 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1937 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1938 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1939 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

1941 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1942 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1943 Mention that these macros are obsolescent.
1944 (Installation Directory Variables): shall -> should
1945 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1946 Mention that it's now safe to use 3 and 4.
1947 (Limitations of Usual Tools): cp -r is now specified by Posix.
1948 Omit longwinded and obsolescent discussion of cp -f.
1949 Modernize discussion of expr, ls.
1950 (Limitations of Make): Modernize discussion of VPATH builds.
1951 Mention $? as a workaround in some cases.
1952 * doc/install.texi (Basic Installation):
1953 Mention "./configure; make; make install" first. Be more
1954 specific about why this file is generic. Remove unnecessary
1955 parens. Remove misleading "only". Remove obsolete advice
1956 about csh. Don't say "configure" takes awhile; say it
1957 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1958 and CC=c99 rather than CC=c89, as these are blessed by current
1959 Posix. Recommend GNU make if doing a VPATH build.
1961 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1963 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1964 examples involving shell prompts.
1966 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1967 and Paul Eggert <eggert@cs.ucla.edu>
1969 * doc/autoconf.texi (Here-Documents): Add details about the
1970 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1971 use "here-documents" instead of "here documents".
1973 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1975 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1977 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1979 * doc/autoconf.texi (File System Conventions): Warn about ":"
1980 anywhere in directory names.
1982 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1984 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1985 about quoting the case statement, just in case.
1986 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1987 was fixed in ksh93g; reported by Ralf Wildenhues.
1989 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1991 * doc/autoconf.texi (System Services): Do not document
1992 overriding EXEEXT via ac_cv_exeext=ext.
1993 (Particular Programs) <AC_PROG_MKDIR_P>:
1994 Document that ${MKDIR_P} understands --.
1995 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1998 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2000 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2001 argument with leading hyphen. Problem reported by Paul Eggert.
2003 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2005 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2006 about quoting ac_try: quote all of it, if any of it seems suspicious.
2007 This means we don't have to worry about ${ or sed any more.
2008 Also, double-quote the case statement, to work around misuses via
2009 underquoting as reported by Ralf Wildenhues in
2010 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2011 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2012 undocumented and dangerous macro.
2013 Problem reported by Ralf Wildenhues in
2014 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2016 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2018 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2019 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2020 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2022 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2024 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2025 since evidently some packages rely on the old, broken behavior.
2026 Problem reported by Ralf Wildenhues in
2027 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2028 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2029 pre-2006-05-26 definitions, but leave in the comments that
2030 these macros are dangerous and should not be used.
2031 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2032 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2033 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2034 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2035 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2037 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2039 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2040 the use of 'tr', since this is our only use of 'tr'.
2042 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2043 and Paul Eggert <eggert@cs.ucla.edu>
2045 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2046 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2048 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2050 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2051 the output file in the `${datarootdir}' test.
2053 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2054 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2056 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2057 mention of `datarootdir' in the input file(s), but literal
2058 `${datarootdir}' in the output file, and we haven't warned yet,
2059 then warn as well: the user may have (erroneously) used
2060 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2061 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2062 * tests/torture.at (datarootdir workaround): Extend this test.
2065 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2066 and Paul Eggert <eggert@cs.ucla.edu>
2068 * doc/autoconf.texi (autoheader Invocation): The first argument to
2069 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2070 alternatives and clear up the language a bit.
2072 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2074 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2075 ac_config_guess, ac_config_sub, ac_configure.
2076 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2077 Fix typo that prevented an unnecessary space from being removed.
2078 Problems reported by Ralf Wildenhues in:
2079 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2081 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2083 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2084 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2085 Don't use the term "thread-safe" to talk about mkdir race
2086 conditions, since the problem is more a process than a thread
2087 issue. Problem reported by Stepan Kasal in:
2088 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2089 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2090 the test for 'install' more closely. Look at MKDIR_P first.
2091 Look in the PATH, and at /opt/sfw/bin.
2092 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2093 Don't bother to try mkdir -p, since we already check mkdir --version;
2094 just look at the version number. (There's no easy way to check
2095 for race-free implementations.)
2096 * tests/tools.at (autoconf: subdirectories): Adjust to above
2097 changes, since MKDIR_P now might end in "/mkdir -p".
2099 * doc/autoconf.texi (autoheader Invocation): Mention that the
2100 first arg of AC_DEFINE_UNQUOTED must be a literal.
2101 Problem reported by Ben Pfaff in
2102 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2104 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2105 * doc/autoconf.texi (Special Chars in Variables): New section.
2106 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2107 (Installation Directory Variables): Quote $(datadir) better.
2108 (Limitations of Builtins): Describe some of eval's trickiness.
2110 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2111 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2112 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2113 in front of every arg, not just trailing args. Quote apostrophes.
2114 (_AC_EVAL_ECHO): New macro.
2115 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2116 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2118 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2119 exposed by quoting of eval argument. Put the command on line line
2121 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2122 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2123 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2124 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2125 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2126 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2127 Use eval more safely.
2128 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2129 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2131 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2132 lines, exposed by quoting of eval argument.
2134 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2135 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2137 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2138 initialization of `ac_cv_exeext', do not override it if it was
2139 already set, unless it was set to `no', for compatibility with
2140 Autoconf-2.13, and comment this.
2141 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2142 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2143 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2144 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2145 Document that this test may be overridden by setting
2148 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2150 Revert these two patches:
2152 2006-04-06 Eric Blake <ebb9@byu.net>
2153 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2154 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2157 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2158 Clean up _AC_COMPILER_EXEEXT* macros.
2159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2160 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2161 ac_file to the name of the default output file and call
2162 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2163 initial `rm' of the candidate files...
2164 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2165 the same list in subsequent `rm' calls, and for the temporary
2166 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2167 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2168 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2169 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2170 no longer needed) by libtool. Make it a cache check.
2171 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2172 copied here by mistake.
2173 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2174 _AC_COMPILER_EXEEXT.
2175 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2176 _AC_COMPILER_OBJEXT directly.
2177 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2179 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2181 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2182 Fix description of how the buggy `sed' works.
2184 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2188 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2189 ENOLCK. Only mention `make -j' when applicable. Only raise
2190 fatal errors when `make -j' is involved. Improve error message.
2192 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2194 * doc/autoconf.texi (Here-Documents): We now know more about
2195 the variable expansion in here documents bug.
2196 Thanks to Tim Rice and Stepan Kasal.
2198 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2199 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2201 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2203 * tests/autotest.at (Multiline command from M4 expansion):
2204 No failure to be expected if the shell quotes newlines in
2205 commands in the `set -x' output. Report by Tim Rice.
2208 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2210 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2211 expansion in the here-documents used by config.status, as that
2212 runs afoul of the Korn shell version M-12/28/93d bug described in
2213 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2214 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2215 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2217 2006-05-23 Jim Meyering <jim@meyering.net>
2219 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2220 Fix typo introduced with 2006-04-02 change. It reversed the sense
2223 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2225 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2226 ac_dB slightly, to save bytes in the script.
2227 Max out at 50 lines, rather than 96; this is more likely
2228 (though not guaranteed) to avoid obscure 'sed' failures.
2230 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2232 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2233 `tr -d -' as bad option argument. Work around this by deleting
2234 an unrelated character.
2235 Report by Tim Rice <tim@multitalents.net>.
2237 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2238 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2239 Stepan Kasal <kasal@ucw.cz>
2241 * doc/autoconf.texi (Particular Programs): Do not promise that
2242 we always prefer the GNU version of the program, and that we
2243 search according to PATH; both rules can have exceptions.
2244 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2245 AC_PROG_SED. Move descriptions of limitations
2246 to the Limitations of Usual Tools section.
2247 (Limitations of Usual Tools) <sed>: Mention script length
2248 limitations with Solaris /usr/ucb/sed.
2249 <grep>: Fix wording for empty alternative. Mention that -c and
2250 -l should not be combined, and that -E and -F should not be
2253 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2254 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2256 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2257 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2259 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2261 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2262 AC_DEFINE is now passed to m4_pattern_allow.
2263 * NEWS: Mention that; likewise for AC_SUBST.
2264 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2265 the parameter to m4_pattern_allow.
2266 * tests/tools.at: Add a check for that.
2268 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2270 * lib/autoconf/status.m4: Fix typos.
2272 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2274 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2275 only the files that this macro generates.
2277 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2279 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2280 the HP-UX sed limitation of 99 commands, labels do not count.
2281 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2283 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2285 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2287 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2288 Import the following fix from coreutils:
2290 2006-01-13 Jim Meyering <jim@meyering.net>
2292 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2293 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2294 not double-quote uses of that variable, to accommodate the rare
2295 case in which getmntent is available in none of the libraries
2296 checked. This happens at least on FreeBSD 5.0.
2298 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2300 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2301 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2302 some other programs unwisely rely on these undocumented vars.
2303 But put in warning comments about them.
2304 Problem reported by Ralf Wildenhues in
2305 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2306 * NEWS: Document that these variables are intended to go away.
2308 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2310 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2311 and set the language to C++ (analogous to the equivalent Fortran
2314 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2315 * doc/autoconf.texi (C++ Compiler): Document it.
2316 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2319 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2321 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2322 that caused config.status to generate 100-command sed scripts; the
2323 portable limit is 99.
2325 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2327 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2328 variable `ac_d' instead of `d' to avoid infringing namespace.
2329 Report by Ralf Menzel.
2331 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2333 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2334 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2335 * tests/tools.at (autoconf: subdirectories): New test, taken from
2336 the corresponding problem report by Ralf Wildenhues in:
2337 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2339 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2340 Quote some uses of shell variables if they might suffer unexpected
2341 globbing. This doesn't fix all instances of quoting problems that
2342 I found, just the easy ones that look safe.
2343 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2344 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2345 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2346 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2347 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

2354 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2356 * bin/autoreconf.in ($help): Reword according to the manual.
2357 Suggested by Olly Betts.
2359 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2360 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2362 * bin/autoreconf.in: Pass the directory argument to
2363 `require_configure_ac'. Fix comment.
2364 * tests/torture.at (Configuring subdirectories): Expose this.
2365 Reported by Olly Betts.
2367 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2369 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2370 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2371 Automake as follows:
2373 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2374 `$configure_in' instead of `configure.in', to preserve
2375 directory component.
2377 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2379 * config/config.guess, config/config.sub, config/texinfo.tex,
2380 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2382 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2384 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2385 test for C99 conformance; (bool) 0.5 is an integer constant
2386 expression, but (bool) -0.5 is not. Problem reported by Fedor
2387 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2389 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2391 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2392 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2393 Warn about obsolete install-sh files. Remove stray sentence
2394 fragment and fix cross reference.
2395 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2396 install -d; this undoes the 2006-05-10 change.
2397 (MKDIR_P): Mark with AN_MAKEVAR.
2398 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2399 that we don't require $INSTALL to be thread-safe. Move comments
2400 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2401 of AC_PROG_INSTALL. Output a message saying that we're checking
2402 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2403 MKDIR_P instead of AC_SUBST.
2404 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2405 Special magic for MKDIR_P, too.
2406 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2408 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2410 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2412 Sync from Automake, as follows:
2414 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2415 * config/install-sh: Initialize IFS, so field splitting isn't
2417 * config/mkinstalldirs: Likewise.
2418 * config/missing: Remove superfluous quotes. Replace all uses of
2419 `[' by `test', for consistency, and for..
2420 * config/missing (sed_minuso, sed_output): New variables.
2421 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2422 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2423 Fixes `missing' to detect `--output' for help2man. Fixes
2424 PR automake/483. Report by Dennis J. Linse.
2425 (autom4te): Document in `missing --help'.
2427 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2429 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2430 * config/install-sh: Don't use 'path' to talk about file names,
2431 as per GNU coding standards. Close a race condition reported by Ralf
2432 Wildenhues and Stepan Kasal. There is still a race condition
2433 on hosts that predate Posix 1003.1-1992, but we can't help this.
2434 Don't mishandle weird characters like space on pre-Posix hosts.
2435 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2436 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2437 AC_PROG_MKDIR_P from AS_MKDIR_P.
2438 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2439 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2440 earlier editions are not (including Automake 1.8.3).
2441 Do not suggest mkinstalldirs for thread-safety.
2442 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2443 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2444 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2445 presence of special characters and race conditions.
2446 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2447 in Autoconf's name space.
2449 2006-05-10 Bruno Haible <bruno@clisp.org>
2450 and Paul Eggert <eggert@cs.ucla.edu>
2452 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2453 from Automake with minor changes.
2454 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2456 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2458 * config/install-sh: Update to Automake CVS version, as follows:
2459 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2460 * lib/install-sh: Simplify the expr implementation of dirname.
2461 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2462 * lib/install-sh: Handle --, and diagnose unknown options.
2464 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2466 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2467 `./autom4te' to create `./testsuite', since the `all' target
2468 will ensure its presence, but `installcheck' should not create
2469 the uninstalled wrappers.
2471 * tests/torture.at (Unusual Automake input files): Skip if we
2472 detect automake < 1.8.
2474 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2476 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2477 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2478 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2481 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2483 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2484 munge (multiple) white space and other oddities.
2485 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2486 single quotes in variable assignment.
2487 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2488 and similar failures by adding multiple spaces, tabs, and other
2490 Report and different test suggested by Francesco Romani
2491 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2493 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2494 single quotes, we only need to search for single quotes; this
2495 both simplifies the search pattern, and makes us less
2496 susceptible to `echo' variations for arguments not containing
2498 (_AC_ARG_VAR_VALIDATE): Likewise.
2500 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2502 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2503 `$*' and IFS concatenation issue with traditional shells and
2504 bash-2.04. Report by Seanster@Seanster.com.
2506 2006-05-03 Bruno Haible <bruno@clisp.org>
2508 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2509 precisely which Mac OS X versions have the od problem.
2511 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2513 * doc/autoconf.texi: Use @option systematically.
2515 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2516 and Bruno Haible <bruno@clisp.org>
2518 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2520 (Integer Overflow): Mention the special case of integer division
2523 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2525 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2526 traditional shells like the Solaris one that do not use the
2527 first IFS character for assembling `$*'.
2528 Prompted by a related report from autoconf_bug@nro.ca.
2530 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2531 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2533 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2534 Mention more problems with the -e option.
2536 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2539 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2541 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2542 in URLs to improve DVI formatted output (requires texinfo 4.6).
2543 (System Services, Systemology, Shellology): Likewise.
2544 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2547 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2549 (Runtime): Fix macro argument names to match description:
2550 `action-if-found' -> `action-if-true' and similarly.
2551 (Obsolete Macros): Likewise.
2552 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2553 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2554 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2556 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2558 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2561 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2564 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2566 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2567 /bin/sh set unsorted output.

2574 (Integer Overflow, Null Pointers, Buffer Overruns):
2575 (Floating Point Portability, Exiting Portably): New sections.
2576 (Writing Test Programs): Fix some langauge. Recommend exiting
2577 with status 1, not merely nonzero. Clarify exit declaration.
2578 (Run Time): Move C exit status stuff to new Exiting Portably section.
2579 (Systemology): Mention Posix and levenez. Update v7 reference.
2580 (Portable Shell): Mention the Posix shell.
2582 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2584 * bin/autoconf.as (me): Replace by as_me.
2586 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2588 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2589 since as_me isn't set yet.
2591 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2593 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2594 a few minor bugs in this area.
2596 * doc/autoconf.texi (Programming in M4sh): Comment out the
2597 documentation of AS_BASENAME, for now.
2598 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2599 (Limitations of Builtins) <basename>: Do not refer to
2601 * bin/autoconf.as (me): Don't use AS_BASENAME.
2602 (dir): Remove the unused variable.
2603 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2604 AS_DETECT_REQUIRED. All uses changed.
2605 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.

2611 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2612 (_AS_DIRNAME_PREPARE): Likewise.
2613 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2614 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2615 (AS_DIRNAME): Use "dirname --".
2617 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2619 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2620 of "run time" and "run-time" changed to "runtime", for consistency.
2621 * lib/autoconf/fortran.m4: Likewise (in comment).
2622 * lib/autoconf/functions.m4: Likewise.
2623 * lib/autoconf/general.m4: Likewise.
2624 * lib/autoconf/headers.m4: Likewise.
2626 * doc/autoconf.texi (Run Time): Document the exit status situation
2627 with more accuracy and detail.
2629 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2631 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2632 Archive is not officially `GNU' any more. Update URL.
2633 (Defining Directories): Likewise
2634 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2636 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2638 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2639 newline from the `trap' code to finish `config.log'; the NetBSD
2640 /bin/sh resets the exit status after an empty command, as
2641 documented in doc/autoconf.texi.
2642 Reported by Dalibor Topic <robilad@kaffe.org>.
2644 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2646 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2647 Suggested by Bruno Haible.
2649 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2651 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2652 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2653 Instead, just list the shells that we know work.
2654 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2655 changed. Be more cautious about the _cv_ variable.
2656 * tests/tools.at (Syntax of the shell scripts): Check the
2657 _cv_ variable once, at first, to avoid an internal autoconf error
2658 when sh -n does not work.
2660 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2662 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2664 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2666 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2667 use ">&-" since we're only 99.999% sure that this is portable,
2668 and since the MinGW bug is fixed in a different way.
2669 * lib/autotest/general.m4 (AT_INIT): Likewise.
2671 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2673 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2674 before opening config.log, to avoid hitting a bug on MinGW.
2676 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2678 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2679 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2680 This works around a MinGW bug reported by Eric Paire.
2681 Make sure that all writes to the log file append to it,
2682 rather than possibly losing data.
2683 * lib/autotest/general.m4 (AT_INIT): Likewise.
2685 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2687 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2690 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2694 * configure.ac (AC_INIT): Bump to 2.59d.
2696 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2700 * Makefile.maint (news-date-check): Do not require a leading `*'
2701 before the release date in NEWS.
2703 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2704 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2706 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2707 the instantiated file do not contain the string 'datarootdir'
2708 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2709 @mandir@, replace the reference '${datarootdir}' by the value.
2710 * tests/torture.at (datarootdir workaround): New test.
2711 * NEWS: Advertise this temporary fixup.
2712 Based on a patch by Bruno Haible, reported and analyzed by
2713 Paul Eggert and Noah Misch.
2715 2006-04-12 Eric Blake <ebb9@byu.net>
2717 * tests/autotest.at (Debugging a failed test): Fix comment.
2719 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2721 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2722 all the changes since 2006-04-07.
2724 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2726 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2727 succeeded, but `ln -s file dir' failed, take care to remove the
2728 leftover target before the next test, to prevent its spurious
2729 failure; also make sure `ln file dir' works before selecting it.
2730 Thanks to Keith Marshall for pointing this out.
2733 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2734 assignments in `at_debug_args', so that we put them correctly
2735 in the `run' script.
2736 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2737 Reported by Eric Blake.
2739 2006-04-11 Eric Blake <ebb9@byu.net>
2741 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2742 top-level tests after micro-suite has been run. Used in...
2743 (Debugging a successful test, Debugging script and environment),
2744 (Debugging a failed test): ...these new tests. The first of these
2746 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2747 macro, split out from...
2748 (AT_INIT): ...here, so that using -d also generates a run script.
2749 Document that -d inhibits top-level logging.
2750 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2751 inhibits top-level logging; debug scripts are created.
2753 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2755 * tests/autotest.at (Empty test, Empty check): New test to check it.
2757 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2760 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2762 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2763 the files if a problem appears. Make the empty *.at files
2764 read-only, too. Proposed by Ralf Wildenhues.
2766 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2768 * config/Makefile.am: Add comment to force updated Makefile.in.
2770 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2771 space only patch to this file, this patch causes the Makefile.in
2772 files that include freeze.mk to be updated, and thus have a
2773 newer time stamp again, which in turn makes a pristine CVS
2774 checkout have correct time stamps.
2776 * Makefile.maint (cvs-sv): New macro, to be used..
2777 (config.guess-url_prefix, config.sub-url_prefix)
2778 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2779 point to CVS text checkout of Gnulib files.
2780 (copyright-check): Bump current year.
2781 (announcement): Do not hard-wire `./announce-gen'.
2782 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2784 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2786 (wget_files): Update config.guess, config.sub, texinfo.tex by
2787 `wget-update', now that their URLs work again.
2789 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2791 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2792 Problem noted by Paul D. Smith.
2794 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2796 * doc/autoconf.texi: Remove unused words from word list.
2797 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2798 .x-sc_trailing_space: New files.
2800 * doc/standards.texi: Sync from gnulib.
2802 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2803 `LIBOBJDIR' as experimental.
2805 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2806 with a target directory; it's internally implemented as `cp'
2807 anyway, but since Autoconf advertises the possibility to use
2808 a target directory when LN_S is `ln -s', we need to find out.

2925 _AS_DETECT_BETTER_SHELL:
2927 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

2978 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2980 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2981 whether `set' quotes correctly: redirect stderr of the tested
2982 `set', and use a subshell, for Ultrix; use `sed' instead of
2983 `grep' for zsh `set' which may write binary output; match only
2984 at the beginning of a line, to avoid false positives.
2985 In order to avoid false positives by unrelated variables with
2986 multiline content, put the dump algorithm in a subshell and
2987 unset all variables containing newlines (except some which are
2988 special to the shell). Warn about cache variables that are

3037 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3038 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3039 2005-07-25 rewrite. Noticed by Noah Misch.
3041 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3042 _AC_PRESERVE_HELP_ORDER, ...

3049 for --help from Cygnus `configure.'
3051 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3192 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3193 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

3195 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3196 initial `rm' of the candidate files...
3197 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3198 the same list in subsequent `rm' calls, and for the temporary

3203 no longer needed) by libtool. Make it a cache check.

4040 calls, so that the final expansion of this macro is shorter.
4041 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4042 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4043 the cleanup there. Use AS_VAR_* macros, to be more general.

4095 Update limitations about when to call AC_CONFIG_HEADERS.
4096 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4097 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4098 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4099 ``Configuration Actions''; fix their index entries.
4101 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4102 options correctly. Process N-M as M-N if M is smaller than N.
4103 Process ranges correctly so that N-N will run only N.

4105 than one test, reinsert the banners for the tests.

4136 When building in place, set srcdir="."; suggested by Tim Van Holder.
4138 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4139 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...

4141 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

4158 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4160 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

4176 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4178 Rewrite substantial part of lib/autoconf/status.m4.
4179 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4180 and CONFIG_COMMANDS are not processed in four separate loops.
4181 Instead, there is one main loop. This alows that the common code
4182 is expanded only once, thus config.status (and configure) is smaller.
4184 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4185 the AC_LIST_FILES and cousins macros are no longer used.
4187 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4188 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4189 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4190 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4191 contain the initialization, nor the for loop, nor the associated
4192 commands; all these go to ...
4193 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4194 _AC_OUTPUT_CONFIG_STATUS.
4195 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4196 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4197 (_AC_OUTPUT_FILE): The creation of the sed script ...
4198 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4199 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4200 _AC_OUTPUT_MAIN_LOOP.
4201 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4202 _AC_CONFIG_COMMANDS): Use ...
4203 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...

4216 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4217 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4218 this didn't belong to the `config commands' section.
4219 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4220 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,

4238 parameter to AC_DIAGNOSE.
4239 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4240 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4241 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4242 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4244 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

4273 (AC_ARG_VAR): ... here.
4274 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and

4337 sed substitution command, so that we allow | in program prefixes
4338 and program suffixes. (& is a problem anyway; we're not fixing
4340 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4341 configure_input, top_builddir, srcdir, etc.
4342 * lib/autotest/general.m4 (AT_INIT): Likewise, for

4353 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

4404 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4405 (AC_SUBST): Call it.
4406 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4407 the directory specific variables; but don't call it for configure_input.
4409 2005-06-28 Derek Price <derek@ximbiot.com>
4411 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4414 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4416 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

4433 from Justace Clutter.
4434 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4435 variable into diagnostic. Make the diagnostic an error, not a warning,
4436 because we really don't support spaces and suchlike in dir names.
4437 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4438 Don't worry about backslashes in srcdir; it can't happen now.

4467 (Special Shell Variables): Fix sed code this in the example.
4468 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4469 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

4482 * doc/autoconf.texi:
4483 Don't mention Solaris versions so much, if a
4484 problem is common to all extant versions of Solaris. Say "SunOS
4485 4" instead of "SunOS" for SunOS 4.
4486 (awk): Mention more of the limitations of traditional Awk.
4487 (cat): Don't talk about cat -v.

4529 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4530 -u, since it outputs chatter if the input files are the same.
4531 Problem reported by Ralf Menzel.
4533 2005-06-08 Derek Price <derek@ximbiot.com>
4535 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4536 renaming them since they are about to be redefined anyhow.
4538 2005-06-08 Derek Price <derek@ximbiot.com>
4540 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4541 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4542 Move m4_undefine to alphabetical order.

4547 * doc/autoconf.texi (Introduction): Likewise.
4548 Reword to avoid some formatting glitches.
4549 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4550 Clarify explanation of HP compiler bug.
4551 Redo example output tp match current CVS snapshot.
4552 Use @example.org in email addresses when the examples
4553 might get inadvertently cut-and-pasted into user code.
4554 Remove example of autom4te usage that doesn't seem to work now.
4555 Use modern AC_INIT (except when the example is meant to be
4556 shown with Autoconf 2.13).
4557 Update ksh info for Solaris 9 and later.
4559 Modernize description of Automake versions a bit.
4560 Don't claim a future version of Autoconf is near.

4570 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4571 Tru64 ksh pattern matching bug. Reported against Libtool by
4572 Albert Chin <libtool@mlists.thewrittenword.com> and
4573 Nicolas Joly <njoly@pasteur.fr>.
4575 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4577 m4_cdr of one-member list was [[]] (one-member list containing an
4578 empty string) instead of [] (an empty list. Callers were skewed to
4579 match this misbehaviour. As a consequence of this:
4580 - m4_foreach([x], [], [foo]) expanded to `foo', while
4581 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4582 This bug has been fixed:
4584 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4585 expand to an empty string; print error msg if called without
4587 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4588 misbehaviour; handle [] and [[]] correctly.

4598 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4599 swallow records with more than 99 fields.
4600 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4601 parse the long line.
4603 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4605 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4606 swallow literals longer than 399. Reported by Ralf Wildenhues.
4607 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

4612 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition

4640 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4641 now contain newlines, and substituted files must be referenced on
4642 a line alone; the sed scripts to substitute them are now very
4644 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4645 commands can be put in a sed script portably.
4646 * doc/autoconf.texi (Setting Output Variables): Document above

4667 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4669 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4670 common code; used in many places in the tree.
4671 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4672 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4674 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4676 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4677 messages when ac_unique_file is not found.
4678 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4679 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4680 commands, for consistency with AC_MSG_ERROR and such.

4689 obsolete; it was never documented.
4690 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4692 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4694 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4695 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4696 (ac_top_builddir): ... this ...
4697 (ac_top_build_prefix): ... to this; the old name is also kept, for
4698 backward compatibility.
4699 (ac_top_builddir_sub): New variable, without the trailing slash,
4701 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

4715 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4716 argument to m4_foreach. I guess it was necessary in the past,
4717 but I think it's a no-op now.
4719 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4721 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4722 ``cat <<_ACEOF'' commands to one.
4723 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''

4791 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4793 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4794 for absolute directory names in one loop.
4795 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4796 abbreviations of --version and --debug.
4798 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4800 * doc/autoconf.texi (Autoconf Language): Be more precise about
4801 quoting rules. Problems noted by Stepan Kasal.
4802 Also, throughout this document, be more careful about white space.
4803 "blank", "white space", and "space" all have different meanings
4804 and we should be careful to say what we mean.
4806 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4808 Fix C++ related problems reported by Werner Lemberg.
4809 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4810 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4811 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4812 avoid problems with C++ and throw.
4813 * tests/compile.at: .cpp, not .cc.
4815 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4817 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4819 * doc/autoconf.texi (Generic Functions): Typos.
4821 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4823 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4824 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4825 set by latest automake.
4827 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4829 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4830 outputs 0 on GNU/Linux these days.
4832 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4834 * doc/autoconf.texi (Autoconf Language): Add more description
4835 about quoting heuristics.
4836 (Limitations of Builtins): Describe "set -" problems.
4838 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4840 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4843 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4844 by AC_DEFINE; it was a mistake.
4845 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4847 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4849 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4851 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4853 * doc/autoconf.texi (External Software): Quadrigraphs are not
4854 processed correctly in AS_HELP_STRING; avoid this in the examples.
4855 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4856 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4857 comment and reduce m4_default([foo], []) to [foo].
4858 (m4_strip): Update the explanation.
4860 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4862 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4863 Remove core.conftest.* too; it's generated by Tru64 5.1.
4864 Problem reported by Jennis Pruett.
4865 * lib/autoconf/functions.m4
4866 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4867 Don't bother to remove core files; AC_RUN_IFELSE should do that
4870 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4872 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

4876 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
4877 Report from Horst Wente.
4879 2005-04-15 Stepan Kasal <kasal@ucw.cz>

4886 * doc/autoconf.texi (External Software, Package Options): Add
4887 examples showing how to implement --with-* and --enable-* options.
4889 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4891 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4892 as well as configure.in. Problem reported by Gregorio Guidi.
4894 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4896 * doc/autoconf.texi (Particular Functions): Use gnulib's current

4909 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4910 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4912 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4914 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4915 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4916 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4917 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4918 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4920 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4922 * NEWS: The configure command now warns you if you attempt to use
4923 a directory whose name contains a special character like space,
4925 * doc/autoconf.texi (Installation Directory Variables): Allow
4926 "," in file names. Do not use \@; it's not a portable regexp.
4927 * bin/Makefile.am (edit): Likewise.
4928 * lib/Makefile.am (edit): Likewise.
4929 * tests/Makefile.am (edit): Likewise.
4930 * tests/semantics.at: Likewise.
4931 * tests/torture.at: Likewise.
4932 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4933 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4934 * doc/autoconf.texi (File System Conventions): Warn about
4935 unportable file names.
4936 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4938 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4939 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4940 ac_pwd, and quote srcdir.
4941 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4943 * doc/autoconf.texi: Fix some systematic formatting problems.
4944 ".)" needs a following @: if not at the end of a sentence, and
4945 similarly for "!)". "etc." should be preceded by a comma.
4946 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4948 2005-03-22 Bruno Haible <bruno@clisp.org>
4950 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4951 argument is often called 'build-aux'.
4953 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4955 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4956 macro AC_TRY_LINK is obsolete.
4957 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4960 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4962 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4963 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4964 from a Common Lisp's `cl'.
4965 (AC_PROG_CXX): Behave according to the documentation: don't
4966 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4967 make the variable CCC precious; use `cl.exe', not `cl'.
4969 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4970 Alexandre Duret-Lutz <adl@gnu.org>
4972 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4973 /dev/null, as "configure" shouldn't read stdin, and this insulates
4974 us from problems (e.g., when testing for "cl"). Also, do this
4975 redirection before invoking "hostname" or "uname", and keep the
4976 original input stream available via...
4977 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4978 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4979 bother with "</dev/null" since it's now done at the top of
4981 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4982 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4983 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

4988 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4990 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4991 newline if neither \c nor -n work, as that would output two
4992 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4994 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4996 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4997 This causes that any required macros inside will get before the if.
4998 * doc/autoconf.texi (autom4te.cache): A typo.
5000 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5002 Undo previous change, except keep the change to
5003 lib/autoconf/programs.m4 that replaced grep with shell
5004 pattern-matching. This is because net-snmp configure reads stdin.
5005 Reported by Noah Misch.
5007 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5009 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5010 from /dev/null, as "configure" shouldn't read stdin, and this
5011 insulates us from problems (e.g., when testing for "cl").
5012 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5013 before invoking "hostname" or "uname".
5014 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5015 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5016 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5017 "</dev/null" since it's now done at the top of 'configure'.
5018 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5019 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5020 Also, replace grep with shell pattern-matching, to save a process.
5022 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5024 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5025 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5026 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5029 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5031 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5032 grep -q isn't portable. Improve grep -s explanation.
5033 Problem reported by Dan Manthey.
5035 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5037 * doc/autoconf.texi (Special Shell Variables): Clarify
5038 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5040 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5042 * doc/autoconf.texi: Use @acronym for DJGPP.
5043 Fix some @code's that should have been @env's, and vice versa.
5044 Sort environment variable names.
5045 Mention that shells no longer inherit IFS.
5046 Don't recommend PATH_SEPARATOR=';' so strongly.
5047 Mention that $RANDOM might expand to the empty string.
5048 "symlink" and "soft link" -> "symbolic link".
5049 Improve mktemp description (reported by Bruno Haible).
5051 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5053 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5054 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5056 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5059 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5061 * NEWS: Mention AT_COPYRIGHT.
5063 * tests/local.at (AT_CMP): Use diff directly on input files rather
5066 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5067 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5069 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5070 and Paul Eggert <eggert@cs.ucla.edu>
5072 * tests/autotest.at (Empty test suite): New test.
5073 * tests/torture.at (Substitute and define special characters)
5074 (Substitute a 2000-byte string, Define to a 2000-byte string)
5075 (Substitute a newline, Define a newline): New tests.
5077 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5079 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5080 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5081 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5082 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5083 (Standard regular expressions): New test.
5084 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5085 excess test name quoting.
5086 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5087 CPPFLAGS to `configure' instead of setting it in `configure'.
5089 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5090 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5093 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5094 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5096 * tests/local.at (AT_CMP): New macro.
5097 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

5099 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5100 (AT_CONFIG_CMP): New macro.
5101 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5102 * tests/c.at (Extensions): Do not exit early.
5103 * tests/atlocal.in: Inherit $GREP.
5105 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5106 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5108 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5109 (AC_COPYRIGHT): Factor header comment portion out and move into...

5125 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5127 Try not to generated lines of unlimited length, as POSIX places a
5128 2047-byte limit on line length of portable text files.
5129 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):

5188 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5189 Update the long comment explaining it.
5191 m4_require no longer writes an ``is required by'' line to the
5192 execution stack. It contains only one bit of non-redundant
5193 information: that the macro was required, not called. And even
5194 this bit is useless in most situations: have you ever met a macro
5195 which both calls and requires the same macro?
5197 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5198 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5205 (_m4_require_call): Use it.
5206 * tests/m4sugar.at (m4_require): Expect output without the
5207 ``is required by'' messages.

5245 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5246 Warn about newline stripping in `` and $(). Update Solaris
5248 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5249 X insulates us from future changes to Posix.
5250 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

5277 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5303 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5304 stored in _m4_divert_diversion or _m4_divert_dump.
5305 (m4_divert_pop): When the parameter is given, compare the symbolic
5306 name with the last diversion pushed on the stack. Previously, the
5307 current diversion was compared with the numeric value of the
5308 diversion given as the parameter.
5309 (m4_require): If the macro hasn't been expanded yet, call ...
5310 (_m4_require_call): this new macro.

5579 (autoconf): Find autoconf.in in the build directory.
5580 * bin/autoconf.in: Delete it; we always build it.
5582 2004-12-08 Noah Misch <noah@cs.caltech.edu>
5584 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
5585 PATH members so as to not prepend an empty element. Move a comment.
5586 * Makefile.am (SUBDIRS): Build in `tests' last.
5587 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
5589 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5591 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5592 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5593 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5594 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
5596 2004-12-07 Stepan Kasal <kasal@ucw.cz>
5598 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

5609 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
5610 out the common code to ...
5611 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
5612 value of the #define--default to 1, iff the macro was called
5613 with exactly one parameter.
5615 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5617 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5618 "char c = '\200';" rather than "char c = 0x80;" as the
5619 latter doesn't conform to the strict C standard due to
5620 overflow on signed char hosts.
5622 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5623 to -qlanglvl=ansi. We don't want to disable extensions.
5625 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5627 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

5643 Automake (not without Autoconf).
5644 (Introduction): Mention lists.gnu.org.
5645 * BUGS: Don't mention bugs.gnu.org.
5646 Remove mention of ancient libtool compatibility problem.
5647 * NEWS: Mention that bugs.gnu.org is kaput.

5675 * doc/autoconf.texi (Autoconf Language): Explain that
5676 ``descriptions'' may not be double quotes.
5677 (Quotation Rule Of Thumb): Likewise.
5678 (Pretty Help Strings): Likewise; remove the wrong comment;
5679 simplify the examples and improve their quoting.
5681 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5683 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5684 the $1_found variable, don't test whether the file is executable;
5685 Both things are checked ...
5686 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5687 the former ``test -f''.
5688 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5690 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

5698 limitations. Reorder paragraphs for clarity.
5700 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
5702 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
5703 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
5704 variants", "Unix", and some related minor wording fixups.
5706 (Shellology, Special Shell Variables): Document that the Zsh
5707 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
5708 to Alexandre Duret-Lutz for this info.
5710 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>

5716 * doc/autoconf.texi (Function Portability): Fix misdescription
5717 of putenv. Problem reported by Michael Wardle.
5719 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
5721 * doc/autoconf.texi (auindex): New macro.
5722 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5723 Problem reported by Stepan Kasal.
5725 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5727 Fix problems reported by Andreas Buening in:
5728 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5729 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5731 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5732 readable; it's not true in OS/2-emx.
5734 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5736 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5737 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5738 (trivial change). Problem and patch reported by Andrew Church in:
5739 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5741 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5743 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
5744 three args in examples. Problem reported by Frederik Fouvry in:

5762 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
5766 * README: Add advice about m4 1.4.2.
5768 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5769 texinfo.tex for now (done by hand now).
5770 * Makefile.maint (wget_files, cvs_files):
5771 Remove ansi2knr.c; nobody uses it.
5772 (ansi2knr.c-url_prefix): Remove.
5773 (cvs-update): Fix test for failure. I don't know why it ever
5776 * doc/autoconf.texi: Update URLs, some of which went stale.
5777 Use @uref rather than @href.
5779 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5780 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5782 * config/config.guess, config/config.sub, config/elisp-comp,
5783 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5784 doc/fdl.texi, doc/standards.texi: Sync with master copy.

5792 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5793 tests/tools.at, tests/torture.at:
5794 Use "file name" rather than "filename" or "path",
5795 to be consistent with the terminology of the GNU coding standards.
5797 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5799 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5800 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5801 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5802 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5804 More fixes to support spaces in the name of the build directory.
5805 This isn't a complete fix but it's an improvement.
5807 * bin/autoconf.as (autom4te_options): New var.
5808 Use it instead of appending to AUTOM4TE, so that we can allow
5809 spaces in the build directory's absolute name.
5810 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5811 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5812 AT_CHECK_NOESCAPE): Likewise.
5813 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5814 main program): Likewise.
5816 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5818 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

5824 * doc/autoconf.texi (Function Portability): Document isinf and
5825 and isnan. From a suggestion by Kevin Ryde.
5827 * lib/Autom4te/General.pm (END): Return correct exit status even
5828 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5830 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5832 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5833 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5834 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5836 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5838 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5839 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5840 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5841 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5842 * lib/autom4te.in (Automake-preselections): Preselect
5843 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5845 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5847 * lib/autom4te.in (Automake-preselections): Preselect
5848 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5851 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5853 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5855 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5856 Document problem with "`""`" in pdksh POSIX mode.
5858 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5860 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5861 with pdksh, too. Problem reported by Patrick Welche via
5863 * doc/autoconf.texi (Shellology): Note that set -o posix is
5864 useful for pkdsh, too.
5866 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5868 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5869 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5870 Don't fail if ENV or BASH_ENV is readonly.
5871 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5872 etc. are read only. Problem reported by Ludovic Courtes.
5874 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5876 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5877 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5880 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5882 * doc/autoconf.texi (File System Conventions): Warn about
5883 names like "aux". Problem reported by Eric Blake.
5885 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5886 by zero instead of array size, so that we can use any arithmetic
5887 constant expression (instead of requiring an integer constant
5888 expression). This allows us to test expressions like DBL_MAX <
5889 LDBL_MAX, which didn't conform to the C standard using the old
5891 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5892 now that we can do floating-point tests at compile time.
5894 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5896 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5897 and LDBL_EPSILON, as the resulting expression isn't an
5898 integer constant expression and violates the C standard.
5899 Problem reported by Nelson H. F. Beebe. Also, check
5900 for "L" suffix, and check that long double doesn't have
5901 worse range or precision than double, that mixed-mode
5902 arithmetic doesn't generate a diagnostic, that double
5903 constants fit in long double.
5905 2004-06-03 Kevin Ryde <user42@zip.com.au>
5907 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5908 malloc(0) and realloc(NULL,size).
5910 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5913 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5915 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5916 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5919 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5921 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5922 can be rewritten using if-then-else. Suggested by Bruno Haible.
5924 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5926 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5927 Problem reported by Stepan Kasal.
5929 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5931 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5932 change). Patch reported by Ralf Wildenhues in
5933 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5935 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5936 function F exists if the compiler and linker let you compile an
5937 expression like (F != 0). Recent versions of GCC optimize away
5938 the reference to F in that case, since every function address must
5939 be nonzero, so the link succeeds even if F does not exist.
5940 Problem reported by Manu in
5941 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5943 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5944 "Unix". Many uses changed.
5945 (Limitations of Builtins): Explain better why the ! command isn't
5948 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>

5951 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5953 2004-05-19 Kevin Ryde <user42@zip.com.au>
5955 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5956 referencing AC_FUNC_STRERROR_R.
5958 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5959 note pessimistic assumption when cross compiling.
5961 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5963 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5964 (until 2004) invoked subcommands with sh -e, contra POSIX.
5965 Reported by Kevin Ryde.
5967 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5969 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5970 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5971 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5972 `test -f " /usr/bin/grep"', which _always_ failed.
5973 (AC_PROG_SED): Ditto bogus PATH fix.
5974 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5975 requires that grep correctly supports _multiple_ `-e' options, rather
5976 than stating only that grep should accept `-e'.
5978 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5980 Port to C99, which requires that 'exit' be declared.
5982 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5983 to ensure that stdlib.h is included.
5984 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5985 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5986 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5987 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5988 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5989 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5990 when using 'exit' in a test; C99 requires that 'exit' be declared.
5992 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5994 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5995 now prefers 'grep' implementations that accept -e.
5996 (Limitations of Usual Tools): Describe problems of traditional
5997 egrep and fgrep with long input lines, and of traditional grep
5999 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6000 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6001 All callers changed. Append /usr/xpg4/bin to the PATH, for
6003 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6004 the user with complaints about multiple -e options.
6005 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6006 Define it with AC_PROG_GREP.
6007 * configure.ac (AC_PROG_GREP): Add.
6008 * lib/freeze.mk (GREP): New macro.
6010 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6012 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6013 a possible candidate only after all others fail, rather than
6014 consulting it first. This improves backward compatibility by
6015 better reflecting the way shell selection occurred in previous
6016 versions of Autoconf, and should help to avoid triggering latent
6017 problems in other packages, such as the one in Automake where zsh
6018 is not handled robustly:
6019 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6020 Although it is not Autoconf's responsibility to work around
6021 problems in Automake, it nevertheless makes sense to avoid
6022 introducing unnecessary incompatibilites.
6024 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6025 Gary V. Vaughan <gary@gnu.org>
6027 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6028 how deeply nested we are when a suitable tool is found, set the
6029 ac_path_TOOL_found flag.
6030 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6031 nested we are in this macro. Break out of all 3 nested loops if
6032 ac_path_TOOL_found is set.
6034 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6036 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6037 of the _AS_PATH_WALK loop too if GNU flavor is found.

6041 * doc/autoconf.texi (Limitations of Make): Update documentation
6042 for `$<'. New entry `Long lines', based on a report from Simon

6046 2004-04-20 Paul Eggert <eggert@twinsun.com>
6048 * tests/c.at (C keywords): Don't assume that GCC supports
6049 "restrict" and "inline", as sufficiently-old GCC versions do not
6050 (also, GCC configured to be in pedantic C89 mode does not).

6071 best tool so far counter rely on the tool path variable name to
6072 avoid checks for one tool being affected by the results of running
6073 the length check on a previous tool.
6075 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6076 match expression argument, as different greps have different

6213 AC_SUBST provides no portable way to escape literal newlines.
6215 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6216 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6217 Darwin uses -lcrt2.o and there's little point to cataloging all
6218 the system variants. Partial fix reported by Andreas Waechter in:

6294 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

6343 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6344 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6345 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6346 not <inttypes.h>. Problem reported by Tim Mooney in

6348 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6351 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6352 otherwise "make check" fails because it forbids cmp (I guess
6353 because cmp treats files as binary on DOS-like systems).

6368 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6369 -std1 disables some useful extensions on Tru64. Problem reported

6376 AS_MKDIR_P succeeds if the destination is a symbolic link
6377 to an existing directory.
6378 (Limitations of Usual Tools): Note that mkdir -p might not
6379 succeed on symlinks to directories.

6399 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6400 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6401 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6402 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6403 AC_COMPILE_IFELSE, since we now assume our caller invokes
6404 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6405 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6406 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6407 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6409 2004-01-07 Paul Eggert <eggert@twinsun.com>
6411 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6412 `"'...'"`, as it's confusing (and I suspect it may not work on
6413 some platforms). The code was incorrect anyway, as it assumed
6414 that \$ evaluated to itself in that context. Reported by
6415 Alexandre Duret-Lutz.
6417 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

6449 Bug reported by David Relson in
6450 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6452 * Makefile.am (autom4te-update):

6470 -c -o might not work. From a suggestion by Kevin Ryde.
6471 (C Compiler, Generating Sources, Limitations
6472 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6473 Don't put '-o' after non-options, as POSIX doesn't allow this.

6771 Problems reported by Eric Sunshine.
6773 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6775 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6776 -mGLOB_options_string stuff for Intel ifc, which can cause
6777 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

6800 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6801 cache variable instead of $G77 to decide whether to include -O2,
6802 since $G77 is specific to Fortran 77.
6804 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6806 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6807 free" flag. Re-order flags tested into rough order of popularity.
6809 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6811 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6812 arguments so that it can be used with syntax identical to

6888 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6889 directory for AC_CONFIG_COMMANDS' first argument exists.
6890 This makes valid the invocation of _AC_SRCPATH that follows.
6891 Reported by Eric Sunshine.
6892 * doc/autoconf.texi (Configuration Commands): Adjust.

6915 The test suite are sometimes assigning timings incorrectly.
6916 Reported by Henk Krus.
6917 Diagnosed by Nicolas Joly.
6919 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6921 Instead of making AT_help a sequence of assignments to grow

6925 (at_times_skip): Flip the meaning and rename as...

6935 * bin/Makefile.am (edit): Handle '@configure_input@'.
6936 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6937 (ifnames): chmod -w.
6938 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6939 executables, not bin/ executables! Otherwise all the magic needed
6940 to find non installed files is turned off. This caused a failure
6941 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6942 as found in its environment (sent by tests/autoreconf): pointing
6943 to bin/autom4te that could not find its files.
6944 * tests/mktests.sh: Force the replacement of generated files, for
6945 the sake of "mv" program that are interactive when overwriting a

7016 Improve the accuracy of the wording about obsolescence.
7017 From a suggestion by Ian Lance Taylor in
7018 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7020 2003-09-05 Paul Eggert <eggert@twinsun.com>
7022 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7023 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7025 2003-09-04 Akim Demaille <akim@epita.fr>
7027 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7030 2003-09-04 Akim Demaille <akim@epita.fr>
7032 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7033 (freeze): When exiting, use $exit_code.
7034 * lib/autoconf/fortran.m4: Comment changes.
7036 2003-09-04 Akim Demaille <akim@epita.fr>
7038 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7040 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7042 Add support for newer Fortran dialects. The F77 interface is
7043 unchanged, and continues to support Fortran 77. New FC macros
7044 correspond to all the old F77 macros, with output variables FC,
7045 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7046 available dialect, but older dialects can be specified. There are
7047 new macros AC_FC_SRCEXT to set the source extension, and
7048 AC_FC_FREEFORM to accept free-form source files.
7050 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7052 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

7063 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
7064 AC_FC_SRCEXT, AC_FC_FREEFORM):
7066 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
7067 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
7068 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7069 Rewrite in terms of the above.
7070 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7071 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
7072 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
7073 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
7075 2003-09-02 Paul Eggert <eggert@twinsun.com>
7077 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7078 Document problems with timestamp resolution that 'make', 'cp -p', and
7081 2003-08-27 Akim Demaille <akim@epita.fr>
7083 * tests/m4sugar.at (cross_warning): Make sure to enable the
7084 output, so that we can track spurious m4sugar output.
7085 * tests/local.at: Require 2.57.
7086 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7087 are defaulted by AT_CHECK anyway.
7088 Use AT_CHECK_AUTOM4TE.
7089 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7092 2003-08-27 Akim Demaille <akim@epita.fr>
7094 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7095 when -Wobsolete is set.
7096 Set it on by default.
7097 Suggested by Klee Dienes.
7099 2003-08-27 Akim Demaille <akim@epita.fr>

7112 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
7115 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
7117 * bin/autoreconf.in (parse_args): Do not pass --no-force to
7118 Automake versions prior to 1.8.
7120 2003-08-25 Akim Demaille <akim@epita.fr>
7122 * doc/autoconf.texi (Header Portability): netinet/if_ether.h.
7125 2003-08-24 Akim Demaille <akim@epita.fr>

7135 (local-checks-available): this.
7138 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
7139 * configure.ac: Require Automake 1.7.6.
7141 2003-08-22 Akim Demaille <akim@epita.fr>
7143 Output stack traces in warnings.
7145 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7146 Replace the former...
7147 (m4_warn): Pass the call stack to _m4_warn.
7148 * bin/autom4te.in: Adjust to output the call stack.
7149 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7151 2003-08-22 Akim Demaille <akim@epita.fr>
7153 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7154 * bin/autom4te.in: Adjust.
7156 2003-08-21 Akim Demaille <akim@epita.fr>
7158 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7160 (&getopt): Adjust the note and verb channels, depending upon
7162 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7163 * bin/autoupdate.in: Adjust.
7164 Use &verb, not &verbose.
7166 2003-08-21 Akim Demaille <akim@epita.fr>
7168 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7170 ($help): Use Autom4te::ChannelDefs::usage.
7171 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7172 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7174 2003-08-21 Akim Demaille <akim@epita.fr>
7176 First stab at preserving warnings between calls to autom4te,
7177 including when the cache is used.
7179 There are still several issues: (i) there are too many runs of m4
7180 (one for include, one for warnings, and some more), (ii) warnings
7181 spreading on several lines are not handled gracefully, (iii) the
7182 code meant to have the call stack display for errors does not work
7183 (its handling should move from m4 to autom4te).
7185 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7187 (@preselect): Add m4_warn.
7188 ($exit_status): Remove, use $exit_code.
7189 ($help): Use Autom4te::ChannelDefs::usage.
7190 (&handle_m4): No longer define the m4_warnings.
7191 At each run, extract and report the warnings.
7192 Always cache the result, including if the exit status is on
7193 failure, since if nothing changes, we should result in the same
7194 failure, hence we can use the cache.
7195 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7196 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7198 (m4_warn): Redefine as a do-nothing: it is its invocation that
7199 matters, as warnings are now reported via traces.
7200 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7201 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7202 the latter reveals calls to the former.
7206 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7208 2003-08-21 Akim Demaille <akim@epita.fr>
7210 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7213 2003-08-21 Akim Demaille <akim@epita.fr>
7215 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7217 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7218 (&parse_warnings): Accept a list of warning requests.
7219 (&usage): Return a string, not a side effect.
7220 (cross): New warning category.
7222 2003-08-21 Akim Demaille <akim@epita.fr>
7224 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7225 (&require_configure_ac): Accept an optional directory argument.
7226 ($configure_ac): Remove.
7227 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7229 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7230 * bin/autoscan.in: Adjust.
7232 2003-08-20 Akim Demaille <akim@epita.fr>
7234 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7235 Reported by Alexandre Duret-Lutz.
7237 2003-08-20 Akim Demaille <akim@epita.fr>
7239 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7240 * bin/autom4te: Adjust.
7241 In particular, be Autoconf tools are really silent when properly
7242 working, bind the verbosity of the 'note' channel to $verbose.
7243 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7244 (&xsystem, &contents): Remove, since they are exported by...
7245 * lib/Autom4te/FileUtils.pm: this.
7247 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7248 * lib/Autom4te/FileUtils.pm: here.
7250 2003-08-20 Akim Demaille <akim@epita.fr>
7252 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7253 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

7259 (autom4te-update): New.
7260 * Makefile.cfg (update): Bind autom4te-update.
7262 2003-08-19 Derek Price <derek@ximbiot.com>

7276 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7278 * lib/autom4te.in (Automake-preselections): Preselect
7279 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
7282 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7284 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
7285 (Autoconf-without-aclocal-m4): ... this new language.
7286 * doc/autoconf.texi (autom4te Invocation): Mention

7298 2003-08-16 Derek Price <derek@ximbiot.com>
7300 * doc/autoconf.texi (Writing testsuite.at): Document defaults for
7301 STDOUT & STDERR arguments.
7303 2003-08-14 Derek Price <derek@ximbiot.com>
7305 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7306 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7307 shorter column three. Add DESCRIPTION to log file content.
7309 2003-08-13 Derek Price <derek@ximbiot.com>
7311 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7314 2003-08-12 Derek Price <derek@ximbiot.com>
7316 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7317 (AT_CHECK_NOESCAPE): Move core functionality to...
7318 (_AT_CHECK): ...this new macro.
7320 2003-08-07 Derek Price <derek@ximbiot.com>
7322 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7323 (AT_CHECK_NOESCAPE): ...to this new macro.
7325 2003-07-31 Paul Eggert <eggert@twinsun.com>
7327 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7328 in Bash 2.01. Problem reported by Brian Gough in
7329 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7331 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7333 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7334 -lcrt1.o, for OS X. (trivial change)
7336 2003-07-07 Paul Eggert <eggert@twinsun.com>
7338 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7339 inside '#ifndef __cplusplus'. Problem reported by
7342 2003-07-06 Bill Clarke <llib@computer.org>
7344 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7345 'long', not 'int', for benefit of Sun's recent C++ compilers
7346 (trivial change). See:
7347 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

7353 * lib/Makefile.am (autom4te.cfg): Make it read only.
7354 Depend on Makefile since it contains substitutions.
7356 * lib/autom4te.in (args): Add local.at? for Autotest args.
7357 This change was made on autom4te.cfg which is generated.
7358 Reported by Raja R. Harinath.
7360 2003-06-25 Akim Demaille <akim@epita.fr>
7362 * doc/autoconf.texi (Header Portability): sys/mount.h.
7363 From Gareth McCaughan.
7365 2003-06-23 Akim Demaille <akim@epita.fr>
7367 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7368 not all of them. This fixes 1. the fact that when testing
7369 Autoconf there are many many config.log, 2. the incorrect use of
7370 top_srcdir to find config.log.
7371 Don't mix the detailed output of failed test with the summary of
7372 failures. Rather, append detailed log afterwards.
7374 2003-06-23 Akim Demaille <akim@epita.fr>
7376 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7377 always run: output config.log on $at_group_log.
7379 2003-06-23 Akim Demaille <akim@epita.fr>
7381 * tests/torture.at (#define header templates): Don't use quotes in
7382 C++ comments as it puzzles Emacs' sh font-lock-mode.
7384 2003-06-23 Akim Demaille <akim@epita.fr>
7386 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7387 * lib/autom4te.cfg (args): Add local.at? for Autotest args.

7397 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7398 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7399 ensuring we add -std1 for full-ANSI.
7401 * doc/autoconf.texi (hdrindex): New macro.
7402 Add index entries for portability of various standard header files.
7404 2003-06-20 Akim Demaille <akim@epita.fr>

7432 (TEST_SCRIPT): New diversion.
7433 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7434 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7435 (AT_INIT): Support for expected failures.
7437 2003-06-02 Akim Demaille <akim@epita.fr>
7439 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7441 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7442 Autoconf nor Automake.
7443 (&contents): New, from Automake.
7446 2003-05-28 Paul Eggert <eggert@twinsun.com>
7448 * NEWS, doc/autoconf.texi (Particular Functions),
7449 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7450 is the inverse of localtime.

7454 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7455 (handle_exec_errors): New function. Work around $! being
7456 altered by WEXITSTATUS.
7457 (xqx, xsystem): Use handle_exec_errors.
7459 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7461 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7462 Do not call `_exit()', simply modify `$?'.
7463 (xsystem): Reset $! before running system, and check it afterward.
7464 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7465 63 for version mismatches.
7467 2003-05-23 Akim Demaille <akim@epita.fr>
7469 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7470 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7471 the middle of a line).
7472 * lib/m4sugar/m4sugar.m4: Likewise.
7473 Remove useless spaces in comments.

7477 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

7479 difference with a plain failure.
7480 * doc/autoconf.texi (Notices): Adjust.

7489 Paul Eggert <eggert@twinsun.com>
7491 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7492 Remove `#include <stdlib.h>' from the list; we should never
7493 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7494 resulting namespace pollution would cause other tests to fail.
7495 Configure scripts run with some older versions of g++ and HP's
7496 aCC would fail due to such an #include. Problems reported by
7497 Matthew Mueller in <http://bugs.debian.org/120704> and by
7499 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7500 In the test, use the test declaration before including <stdlib.h>,
7501 as that's closer to how it'll be used.
7503 2003-05-23 Akim Demaille <akim@epita.fr>
7505 * doc/autoconf.texi (Header Portability): ucred.h.
7508 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7510 Overhaul Autotest's logging: generate separate log files
7511 in testsuite.dir/NNN/testsuite.log, and append them to

7514 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7515 file descriptor, write 0 to at_status_file instead of setting
7516 at_status=0, initialize some new variables (at_status_file,
7517 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7518 to rerun the tests, instead append the at_group_log to the
7519 at_suite_log when a test fails.
7520 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7521 with the AS_MESSAGE_LOG_FD redirected to stdout.
7522 (AT_CLEANUP): save the output status in $at_status_file
7523 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7525 (AT_CHECK): since tests are run with a redirected stdout,
7526 and used to be re-run in verbose mode, turn some $at_verbose
7527 into echo, and don't redirect the output of testing stdout
7530 * lib/autotest/autoconf.texi (testsuite Scripts): Update

7651 2003-05-06 Akim Demaille <akim@epita.fr>
7653 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7654 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7655 by aclocal.m4 is changed it might require the importing of another
7656 m4 extension file, i.e., aclocal must be run.
7658 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.

7677 (AT_CLEANUP): Add `;' to end of at_help_all.
7678 (AT_INIT): Allow --keywords to be specified more than once. When

7929 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7930 defined, to support freestanding compilers. This should fix the
7931 bug reported by Momchil Velkov in
7932 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7934 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

7970 * Makefile.maint: Sync with Bison, i.e.:
7971 (po-check): Scan .l and .y files instead of the
7972 .c and the .h files that they generate. This fixes the bug
7973 reported by Tim Van Holder in:

8034 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8036 We _have_ to stop using the old compatibility scheme that tried to
8037 avoid useless backslashes because Libtool 1.4.3 contains a
8038 AC_DEFINE([error_t], [int],
8039 [Define to a type to use for \`error_t' if it is not
8040 otherwise available.])
8041 We _have_ to quote the single quote and backslashes with \. The
8042 old compatibility scheme saw that ` was backslashed, and therefore
8043 did not quote the single quote. Hence before this patch, Autoconf
8044 was not compatible with Libtool.

8498 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8499 aclocal invocation, as Gettext macros might not be visible to
8501 Instead of blindly running autopoint, scan configure.ac (not the

8535 * tests/torture.at (Configuring subdirectories): Be robust to

8573 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8574 (.m4.m4f): Don't pass --prepend-include, since that's done by
8575 tests/autom4te itself.
8576 * lib/autoscan/Makefile.am: Include freeze.mk.
8577 (autoscan.list): New target --this file is no longer a source.
8578 (autoscan.pre): New file.
8580 2002-09-28 Akim Demaille <akim@epita.fr>
8582 * bin/autoscan.in (@kinds): Make them singular.

8593 * lib/autoscan/autoscan.list: this.
8594 * bin/autoscan.in (&init_tables): Adjust.
8596 2002-09-28 Akim Demaille <akim@epita.fr>
8598 * lib/autoscan/functions, lib/autoscan/headers,
8599 * lib/autoscan/identifiers, lib/autoscan/makevars,

8601 `functions' line is now prefixed with `function:'.
8602 * bin/autoscan.in (&init_tables): Adjust.
8604 2002-09-28 Akim Demaille <akim@epita.fr>
8606 From now on, autoscan files must always map a macro name to a
8607 word: there is no `default' macro for autoscan.
8609 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8611 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8614 2002-09-28 Akim Demaille <akim@epita.fr>

8617 (&used): Keep only track of the words we might be interested in.

8628 2002-09-27 Akim Demaille <akim@epita.fr>
8630 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8632 Thanks to Bill Moseley and Paul Eggert.
8633 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8634 the tmpdir must be created.
8635 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8636 dir be in the build tree, instead of $TMPDIR.

8641 (&parse_args): Drop obsolete undocumented options.

8652 2002-09-26 Akim Demaille <akim@epita.fr>
8654 Single suffix rules and seperated dependencies are not portable.
8656 * doc/autoconf.texi (Installation Directory Variables): Update.
8657 (Limitations of Make): Some about `Single Suffix Rules and
8658 Separated Dependencies'.
8659 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8660 (ifnames, autoscan, autom4te): Un-factor into several rules.
8662 2002-09-25 Paul Eggert <eggert@twinsun.com>
8664 * BUGS (Interoperability bugs): New section. Mention libtool
8665 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8667 2002-09-24 Paul Eggert <eggert@twinsun.com>
8669 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8670 make handles suffix-rules differently from GNU make.
8672 * bin/Makefile.am (SUFFIXES, .in): Remove.
8673 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8674 Move the body of the old .in rule here.
8676 2002-09-16 Akim Demaille <akim@epita.fr>
8678 i960 compilers create `b.out' files by default.
8679 Reported by Ralf Corsepius.
8681 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8682 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8684 2002-09-13 Paul Eggert <eggert@twinsun.com>

8687 reference to `struct timezone' in the description of
8690 2002-09-13 Akim Demaille <akim@epita.fr>
8694 * config/config.sub, config/config.guess: Update.
8695 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8696 * Makefile.am: Adjust.
8698 2002-09-13 Akim Demaille <akim@epita.fr>
8700 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8701 reading config.log when the compiler is rejected.
8702 Suggested by Guido Draheim.
8704 2002-09-13 Akim Demaille <akim@epita.fr>
8706 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8707 (chdir_init) might hang when stat'ing mounted directories.
8708 Reported by Vance Shipley.
8710 2002-09-12 Akim Demaille <akim@epita.fr>
8712 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8715 2002-09-12 Akim Demaille <akim@epita.fr>
8717 * doc/autoconf.texi (Defining Symbols): Present two different
8718 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8719 difference between 1 argument calls, and 2-3 argument calls.
8721 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8723 * doc/autoconf.texi: Review grammar and punctuation.
8725 2002-09-11 Paul Eggert <eggert@twinsun.com>
8727 * doc/autoconf.texi: Fix minor formatting, spelling, and
8729 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8730 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8733 2002-09-11 Akim Demaille <akim@epita.fr>
8735 * doc/autoconf.texi (Questions): Rename as...
8737 (Defining Directories): New.
8739 2002-09-09 Akim Demaille <akim@epita.fr>
8741 * doc/autoconf.texi (Making testsuite Scripts): Update.
8742 Suggested by Nishio Futoshi.
8744 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8746 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8747 plain `@' is wanted.
8749 2002-09-09 Akim Demaille <akim@epita.fr>
8751 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8752 `duplicates', since the algorithm was too naive and could keep
8753 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8754 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8755 Reported by Ralf Corsepius.
8756 * tests/torture.at (Configuring subdirectories): Exercise these
8759 2002-09-09 Akim Demaille <akim@epita.fr>
8761 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8762 looking for a replacement file.
8763 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8764 directory is relative.
8765 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8766 directory definition.
8767 Reported by Andreas Schwab and Jim Meyering.
8769 2002-09-06 Akim Demaille <akim@epita.fr>
8771 * doc/autoconf.texi (Setting Output Variables): Clarify what
8772 precious variables are.
8773 Suggested by Pontus Skoeld.
8775 2002-09-05 Akim Demaille <akim@epita.fr>
8777 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8778 (ifnames, autoscan, autom4te): Since we don't only depend on
8779 configure.ac variables (such as VERSION etc.), but also on prefix
8780 and so forth, depend on Makefile, not configure.ac.
8781 Reported by Alexandre Duret-Lutz.
8782 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8784 2002-09-05 Kevin Ryde <user42@zip.com.au>
8786 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8787 doesn't seem to be confined to ia64, just say "some versions".
8789 2002-09-04 Akim Demaille <akim@epita.fr>
8791 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8793 * Makefile.am (maintainer-clean-local): Remove.
8794 (MAINTAINERCLEANFILES): Remove COPYING.
8796 2002-09-03 Paul Eggert <eggert@twinsun.com>
8798 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8799 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8802 2002-09-03 Akim Demaille <akim@epita.fr>
8804 * configure.ac: Bump to 2.53d.
8805 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8806 as of today, on Automake's team suggestion.
8808 2002-09-03 Akim Demaille <akim@epita.fr>
8812 2002-09-02 Akim Demaille <akim@epita.fr>
8814 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8816 * configure.ac: Disable SITE_MACRO_DIR.
8818 2002-09-02 Jim Meyering <meyering@lucent.com>
8820 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8821 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8822 Also, tweak grammar: s/make sure to/be sure to/.
8824 2002-09-02 Paul Eggert <eggert@twinsun.com>
8826 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8827 directory names are generally preferable to physical names.
8829 2002-09-02 Akim Demaille <akim@epita.fr>
8831 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8832 Reported by Raja R. Harinath.
8833 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8834 * bin/autoupdate.in: Use error instead of die.
8836 2002-09-01 Paul Eggert <eggert@twinsun.com>
8838 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8839 ordinary shell concatenation rather than echo+tr+sed command that
8840 runs afoul of a long-line-related sed bug in Solaris 8.
8842 * bin/autoheader.in (parse_args): --warning -> --warnings.
8844 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8845 stdout, as traditional "ls" does.
8846 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8847 _AC_COMPILER_EXEEXT_O): Likewise.
8848 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8850 * bin/autoconf.as: Add --prepend-include option. This patch was
8851 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8852 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8854 * bin/autoconf.in, configure: Regenerate.
8856 * doc/autoconf.texi (Special Shell Variables): Mention
8857 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8859 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8860 MAILPATH and set PS1, PS2, PS4 to default values, to work
8861 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8862 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8863 the Autoconf documentation specifies; fall back to "unset" only if
8864 this fails. Use a shell for-loop for this rather than an m4 loop,
8865 to shorten the output script.
8867 2002-08-30 Paul Eggert <eggert@twinsun.com>
8869 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8870 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8871 for the CDPATH problem. Document PWD.
8872 (Limitations of Builtins): Document the problem that "cd $foo" and
8873 "ls $foo" may refer to different directories in shells conforming
8874 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8875 example, since the old example is now out of date.
8877 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8878 FOO" and "ls FOO" talk about different directories; this catches
8879 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8882 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8883 of rolling our own unset.
8884 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8885 in practice we needn't worry about CDPATH if unset doesn't work.
8887 * Makefile.in, aclocal.m4, bin/Makefile.in,
8888 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8889 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8890 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8891 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8892 tests/Makefile.in: Regenerate with Automake 1.6.3.
8894 * config/config.guess, config/config.sub, config/mkinstalldirs:
8897 * configure: Regenerate with self.
8899 2002-08-30 Kevin Ryde <user42@zip.com.au>
8901 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8904 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8906 * bin/autom4te.in (Request::load): Correctly test for "do" read
8909 2002-08-29 Akim Demaille <akim@epita.fr>
8911 * lib/Autom4te/General.pm (&xqx): New.
8912 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8913 hand, which is not portable.
8915 * bin/autom4te.in: Use them.
8916 Use &error instead of die.
8917 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8920 2002-08-17 Paul Eggert <eggert@twinsun.com>
8922 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8923 default list of compilers to try, since it was long ago superseded
8924 by the ksh fc builtin. Suggested by Steven G. Johnson.
8926 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8928 * doc/autoconf.texi (Invoking autom4te): End the option table,
8929 fixing a bug introduced by the previous patch.
8930 (Limitations of Make): Add a 'target lookup' subentry in the
8931 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8933 2002-07-29 Mark D. Roth <roth@feep.net>
8935 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8936 options and use $AUTOM4TE_PATH.
8937 * doc/autoconf.texi: Remove documentation of autom4te
8938 --include-envvar and --site-macro-subdir options and document
8939 use of $AUTOM4TE_PATH.
8940 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8941 arguments from each language section.
8943 2002-07-29 Paul Eggert <eggert@twinsun.com>
8945 * doc/install.texi: Include copyright symbol in copyright notice.
8947 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8949 (AM_MAKEINFOFLAGS): New macro.
8950 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8951 * Makefile.am (INSTALL): Use the new macros.
8952 Use -o rather than --output, since "missing" does not grok --output.
8954 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8956 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8957 comments do not always work. Never trust the exit status of
8960 2002-07-24 Kevin Ryde <user42@zip.com.au>
8962 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8963 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8965 2002-07-23 Paul Eggert <eggert@twinsun.com>
8967 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8968 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8969 apparently treats PATH="nonexistent" as if it contained ".".
8970 Bug reported by Stefan `Sec' Zehl.
8972 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8974 * doc/autoconf.texi (Limitations of Make): Mention the special
8975 handling of the obj/ directory by BSD make.
8977 2002-07-20 Kevin Ryde <user42@zip.com.au>
8979 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8982 2002-07-19 Akim Demaille <akim@epita.fr>
8984 * doc/autoconf.texi (Function Portability): `exit'.

9011 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
9012 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
9014 2002-07-17 Russ Allbery <rra@stanford.edu>
9016 * doc/autoconf.texi (Initializing configure): Clarify the
9017 description of the tarname default.

9046 * bin/autoupdate.in: Add --prepend-include option.
9047 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
9048 macro directory, remove note that include path directories are
9049 used in reverse order, and document --prepend-include option.
9050 * lib/autom4te.in: Use --prepend-include instead of --include.
9051 * tests/wrapsh.in: Use --prepend-include instead of --include.
9053 2002-07-17 Akim Demaille <akim@epita.fr>

9240 This improves on an earlier suggestion by H. Peter Anvin.
9242 2002-05-16 Paul Eggert <eggert@twinsun.com>
9244 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9245 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9246 Both macros now accept an optional source-dir arg.
9247 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9249 * NEWS: Document this.
9250 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9252 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9253 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

9263 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9264 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9265 and it causes a 'test' syntax error if it fails.
9266 Bug reported by Stephen Gildea.
9268 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9269 If prototypes are supported, use them to check this at compile-time,
9270 instead of trying to check it at run-time. If we must do a run-time
9271 check, assume that setvbuf is standard when cross-compiling, as
9272 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9273 Bug reported by Paul D. Smith.
9275 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9276 argument specifying location of getloadavg.c. This removes a
9277 FIXME. This idea was taken from Jim Meyering's implementation in
9279 * doc/autoconf.texi (Particular Functions): Document this.
9280 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9281 that's what the code does; this fixes a bug reported by

9286 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9287 autopoint instead of gettextize.
9288 ($uses_alocal): Rename as...
9289 ($uses_aclocal): this.
9290 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9291 Suggested by Bruno Haible.

9295 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9297 2002-04-29 Paul Eggert <eggert@twinsun.com>
9299 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9300 files to be 1 second older; just set them to be the same time.
9301 Also, sleep 1 second after the first aclocal, to work around
9302 problems with sub-second time stamps on the input files.
9304 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9306 * doc/autoconf.texi: Mention "set -e -x" lossage

9313 From Christian Cornelssen.
9315 2002-04-29 Akim Demaille <akim@epita.fr>
9317 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9318 of lack of $LINENO support, then the test will compare the $LINENO
9319 in testsuite vs. the lineno in the test file. This is wrong, of
9321 Be sure to protect it.
9322 Reported by Patrick Welche.
9324 2002-04-25 Akim Demaille <akim@epita.fr>
9326 * doc/autoconf.texi (Obsolete Macros): Typo.
9327 Reported by Vladimir Volovich.
9329 2002-04-25 Akim Demaille <akim@epita.fr>
9331 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9332 than some of the input files, hence, on the second run of aclocal,
9333 if some of its input are younger, make them older.
9334 Suggested by Paul Eggert.
9336 2002-04-25 Akim Demaille <akim@epita.fr>
9338 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

9343 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9344 and ac_subst_vars be sh variables containing the list of
9345 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9347 (_AC_INIT_PREPARE): Use them to log them.
9348 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9349 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9350 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9351 _AC_SUBST_FILES and _AC_SUBST_VARS.

9354 2002-04-24 Akim Demaille <akim@epita.fr>
9356 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9357 autoheader, so that automake does not complain about a missing
9358 config.h.in that was to be created.
9360 2002-04-23 Akim Demaille <akim@epita.fr>

9570 2002-03-28 Kevin Ryde <user42@zip.com.au>
9572 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9573 to avoid versions of HP C which don't allow that.
9575 2002-03-27 Paul Eggert <eggert@twinsun.com>
9577 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9578 (AS_SHELL_SANITIZE): Invoke it.

9589 2002-03-25 Paul Eggert <eggert@twinsun.com>
9591 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9592 as POSIX requires, as it doesn't work with Zsh.
9593 * doc/autoconf.texi (Assignments): Document the problem.
9595 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9597 * doc/autoconf.texi (Limitations of Make): Mention more issue
9598 about VPATH, overriding of macros in sub-makes, and handling of
9601 2002-03-21 Paul Eggert <eggert@twinsun.com>
9603 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9604 problem with here-document buffer boundaries.
9606 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9607 when reinvoking the shell, to work around problems with installers
9608 who put strange things like "cd" commands in their environments.

9624 From Nishio Futoshi.
9626 2002-03-19 Akim Demaille <akim@epita.fr>
9628 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

9632 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9633 (Limitations of Usual Tools): Add mkdir section.
9635 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9636 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9637 back on AS_DIRNAME to compute prefixes otherwise; this is
9638 roughly what mkinstalldirs does. That way, we need not have
9639 our own filename disassembler. The old disassembler did not
9640 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9642 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9643 Create at_test_all by a series of assignments,
9644 not by a single assignment of a long string. The latter causes ksh
9645 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9646 presumably because of a buffer overrun.
9648 2002-03-14 Paul Eggert <eggert@twinsun.com>
9650 * lib/autotest/general.m4 (at_times_skip):
9651 Renamed from at_times. Now a boolean.
9652 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9653 says 'times: not found'.

9700 2002-03-08 Akim Demaille <akim@epita.fr>
9702 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9703 aliases the actual variables, and modifications of the former
9706 2002-03-08 Akim Demaille <akim@epita.fr>
9708 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9709 because of C-c: have m4 output in tmp files, then mv them.

9741 2002-03-04 Akim Demaille <akim@epita.fr>
9743 * doc/autoconf.texi (Transforming Names): Equality between target
9744 and host is irrelevant.
9745 (Specifying Names, Canonicalizing): Remove all references to the
9746 backward compatibility hooks. Rather, collect them all into...
9747 (Hosts and Cross-Compilation): this new section.
9748 * doc/install.texi (System Type): Ditto.
9749 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9750 that `--host' implies cross-compilation.
9752 2002-03-04 Akim Demaille <akim@epita.fr>
9754 * doc/autoconf.texi (Evaluation Macros): New.
9755 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9757 (_m4_foreach): Define the variant with immediate evaluation so
9758 that it contains exactly the items, not an expression which
9759 evaluation is the current item.
9760 (m4_re_string, m4_re_word): Don't over quote them.
9762 2002-03-04 Akim Demaille <akim@epita.fr>
9764 Instead of having stacking `shift's evaluated at the end, let
9765 `foreach' loops immediately evaluate them.
9767 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9768 $*. This is the n-th time I change my mind, but hopefully this is
9771 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9773 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9774 it was only a hack for m4_text_wrap.
9775 (m4_car2): Remove, replaced by...
9777 (_m4_foreach): Adjust.
9778 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9779 m4_bpatsubst for clarification.
9781 2002-03-04 Akim Demaille <akim@epita.fr>

9831 AC_PREFIX_PROGRAM fails with dashed program names
9833 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9834 variable when looking for the prefix program.

9870 2002-02-05 Akim Demaille <akim@epita.fr>
9872 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

9937 2002-01-28 Akim Demaille <akim@epita.fr>
9939 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9940 AUTOTEST_PATH *after* it was set.
9941 Don't put `.' in the PATH: the user should be precise and `./' if
9942 needed. In addition, given that the test suite does some `cd', if
9943 `.' is in the path, the `tested programs' sections will report
9944 programs found in the test suite's directory, while during the
9945 tests (performed in their own directory), these programs are no
9946 longer visible. In other words, the results is confusing and

10095 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10096 Remove $filepath, useless.
10097 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10098 variables, they are really part of the tokens.
10099 Split the input line on spaces and then look for tokens.
10100 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10101 because of `lex$U.$(OBJEXT)'.
10102 (&scan_files): Use "@list" instead of join.
10103 * doc/Makefile.am (CLEANFILES): Add *.fns.
10105 2001-11-26 Akim Demaille <akim@epita.fr>
10107 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10108 Remove, replaced by...
10109 * tests/wrappl.in: Be common for all the Perl executables.
10110 In particular autoscan and autoheader want -I.
10111 * configure.ac: Adjust.
10112 * lib/autoscan/headers: errno.h is portable.
10114 2001-11-26 Akim Demaille <akim@epita.fr>
10116 * bin/autoscan.in (used): New.
10119 2001-11-26 Akim Demaille <akim@epita.fr>
10121 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10123 (&scan_sh_file): Remove a duplicate pattern.
10124 (&check_configure_ac): Use long options.
10125 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10127 2001-11-26 Akim Demaille <akim@epita.fr>
10129 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10130 Before, having a line containing the opening of a multi line
10131 comment made the whole line be ignored.
10133 2001-11-26 Akim Demaille <akim@epita.fr>
10135 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10136 (testsuite Scripts): Be one of its subsection.
10137 (Autotest Logs): New.
10139 2001-11-26 Akim Demaille <akim@epita.fr>
10141 Test groups are now run two directories deeper.
10143 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10144 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10146 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10147 top_srcdir, builddir and top_builddir.
10148 Use `at_*dir' relatively to the directory containing the
10149 suite, use `*dir' when relatively to the current group dir.
10151 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10153 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10154 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10155 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10158 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10160 * doc/autoconf.texi (Using System Type): Add an example of `case
10161 $host' usage so people quit using `case $target' everywhere.
10163 2001-11-22 Akim Demaille <akim@epita.fr>
10165 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10166 spotted by Jim Meyering.
10168 2001-11-16 Paul Eggert <eggert@twinsun.com>
10170 This patch implements a `long double' suggestion by Oliver Kiddle.
10172 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10173 static, to catch errors if the value isn't known at compile-time
10174 and the compiler supports dynamic arrays. Change its name from
10175 `_array_' to `test_array' to avoid potential name clashes.
10176 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10177 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10178 better than double. Catch a bug in GCC 2.95.2 x86.
10179 * doc/autoconf.texi (C Compiler): Document the above.
10182 2001-11-13 Akim Demaille <akim@epita.fr>
10184 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10186 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10188 2001-11-13 Akim Demaille <akim@epita.fr>
10190 * lib/autotest/general.m4 (AT_INIT): After having run the test
10191 group, go back to the initial directory, not to at_suite_dir.
10193 2001-11-13 Akim Demaille <akim@epita.fr>
10195 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10196 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10197 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10199 (AT_CHECK_CONFIGURE): Use absolute paths.
10200 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10201 The problem is still the old one: there is no means in M4 (that I
10202 know about) to create a defining macro, because there is no means
10203 to create `$1' etc., therefore, the defining macro ``swallows''
10204 all the arguments meant to the defined macro.
10206 2001-11-13 Akim Demaille <akim@epita.fr>
10208 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10209 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10211 * tests/aclocal.m4: Remove, as it is no longer used.
10213 2001-11-13 Akim Demaille <akim@epita.fr>
10215 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10216 variable names when referring to a single test group, or to
10217 `suite' when referring to the whole test suite.
10218 `at_last_test' is removed: m4 compute at_format itself.
10219 (at_stdout, at_stder1, at_stderr): New variables.
10220 (AT_CHECK): Use them.
10222 2001-11-13 Akim Demaille <akim@epita.fr>
10224 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10226 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10227 Do it as soon as a test fails, don't wait till the end of the test
10229 Don't remove $as_me.[0-9]*, since these files no longer exist.
10231 2001-11-13 Akim Demaille <akim@epita.fr>
10233 * tests/tools.at: Use absolute paths, since we are no longer run
10236 2001-11-13 Akim Demaille <akim@epita.fr>
10238 Now that tests are running in their own private dir, there is no
10239 need to list the files to remove at the end of tests groups.
10241 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10242 (AT_data_files, at_data_files): Remove.
10243 (AT_CLEANUP, AT_DATA): Simplify.
10245 Remove the group dir if !debug && !failed.
10246 * tests/atspecific.m4: Adjust.
10248 2001-11-13 Akim Demaille <akim@epita.fr>
10250 Start a new layout for Autotest: `testsuite' creates
10251 `testsuite.dir' in which the at-check-line etc. files are to be
10252 found, and `testsuite.dir/003' where the test group 3 is run.
10254 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10255 at_check_line_file, at_format, at_test_normalized, at_group_dir
10257 Create the directories.
10258 Use absolute paths for at- files.
10259 (AT_CHECK): Adjust.
10261 2001-11-11 Michael Matz <matz@kde.org>
10263 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10265 (m4_car): Properly quote arguments.
10267 2001-11-13 Akim Demaille <akim@epita.fr>
10269 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10270 with stricter rules on LIBOBJS.
10272 2001-11-12 Paul Eggert <eggert@twinsun.com>
10274 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10275 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10278 2001-11-12 Akim Demaille <akim@epita.fr>
10280 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10282 2001-11-12 Akim Demaille <akim@epita.fr>
10284 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10285 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10286 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10287 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10288 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10289 specify to what the macro should be defined (typically to 1).
10291 2001-11-12 Akim Demaille <akim@epita.fr>
10293 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10296 2001-11-12 Akim Demaille <akim@epita.fr>
10298 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10299 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10300 definition used by Automake where LEX is +/- "${missing} lex" and
10301 `missing' itself contains variables.
10303 2001-11-12 Akim Demaille <akim@epita.fr>
10305 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10306 Now that M4sh pushes BODY, the comments were output at the end of
10309 2001-11-08 Akim Demaille <akim@epita.fr>
10311 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10312 that we can trace macros from aclocal.m4.
10313 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10314 obsoleted, and redirect to the former anyway.
10315 Reported by Ralf Corsepius.
10317 2001-11-08 Akim Demaille <akim@epita.fr>
10319 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10320 processed only if present.
10321 * tests/torture.at (Configuring subdirectories): Use autoreconf
10322 instead of successive calls to autoconf.
10323 Add a nonexistent subdirectory to exercise the patch above.
10324 Reported by Ralf Corsepius.
10326 2001-11-08 Kevin Ryde <user42@zip.com.au>
10328 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10329 doesn't accept .S files.
10331 2001-11-07 Akim Demaille <akim@epita.fr>
10333 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10334 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10335 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10336 * bin/autom4te.in (warn_forbidden): New.
10337 (handle_output): Use it.
10338 Read m4_pattern_forbid with messages.
10340 2001-11-05 Akim Demaille <akim@epita.fr>
10342 * bin/autom4te.in (--normalize): Remove.
10343 * lib/autom4te.in: Adjust.
10345 2001-11-05 Akim Demaille <akim@epita.fr>
10347 * tests/Makefile.am (testsuite): Rename this target as...
10348 ($(TESTSUITE)): this.
10351 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10353 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10354 the --prefix option, also remove it's argument.
10356 2001-11-05 Akim Demaille <akim@epita.fr>
10358 * doc/autoconf.texi (testsuite Invocation): Update.
10359 (Writing testsuite.at): Update.
10361 2001-11-03 Akim Demaille <akim@epita.fr>
10363 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10365 2001-11-03 Akim Demaille <akim@epita.fr>
10367 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10368 (&file_name_is_absolute): New, wrappers around routines from
10370 Use and export them.
10371 (&find_configure_ac): Optionally take a directory where to look at.
10372 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10374 Default @ARGV to `.', not find_configure_ac.
10375 (&autoreconf): Argument is a directory.
10376 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10377 * doc/autoconf.texi (autoreconf Invocation): Update.
10379 2001-11-03 Akim Demaille <akim@epita.fr>
10381 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10382 (@export_forward_subs): New.
10383 Add basename, dirname, and fileparse.
10385 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10386 Don't look for aclocal flags if we already know aclocal is not
10388 Move aclocal.m4t only if it exists.
10389 Reported by Ezra Peisach.
10391 2001-11-03 Akim Demaille <akim@epita.fr>
10393 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10394 passed on command line, defaulting to ./configure.ac if present.
10395 (&maybe_autoreconf, File::Find): Remove, unused.
10396 (&autoreconf): If autoconf is not used, don't try to trace.
10398 2001-11-02 Akim Demaille <akim@epita.fr>
10400 * configure.ac: Bump to 2.52g.
10402 2001-11-02 Akim Demaille <akim@epita.fr>
10406 2001-11-02 Akim Demaille <akim@epita.fr>
10408 * config/config.guess, config/config.sub, doc/standards.texi:
10409 * config/lispdir.m4: Update from masters.
10410 * configure.ac: Bump to 2.52f.
10412 2001-11-02 Akim Demaille <akim@epita.fr>
10414 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10415 Don't run aclocal when aclocal.m4 is not from aclocal.
10417 Don't run libtoolize and gettextize if --install is not given.
10419 2001-11-01 Paul Eggert <eggert@twinsun.com>
10421 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10422 be invoked before _AS_LINENO_PREPARE.
10423 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10424 than character ranges.
10426 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10427 invoking AS_BASENAME. Set the locale variables to 'C' if
10428 possible, as POSIX requires this to get the traditional
10430 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10432 2001-10-31 Paul Eggert <eggert@twinsun.com>
10434 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10435 with {}, as that triggers a bug in Bash 2.05.
10437 (_AS_LINENO_PREPARE): Use Sed rather than
10438 Awk. Fix the sed prepass to work even if there are multiple
10439 instances of $LINENO on the same line. Do not substitute for
10440 other variables like $LINENOT. Do not check file dates; such a
10441 check is unreliable on sufficiently fast machines, and removing
10442 the check makes the code simpler and more reliable. Check for
10443 output and chmod failures.
10445 * doc/autoconf.texi (Special Shell Variables): Document
10448 2001-10-31 Akim Demaille <akim@epita.fr>
10450 * tests/Makefile.am (atconfig): Remove this target, Automake
10453 2001-10-31 Akim Demaille <akim@epita.fr>
10455 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10456 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10457 provided, while it is optional.
10458 * configure.ac: Adjust.
10460 2001-10-26 Paul Eggert <eggert@twinsun.com>
10462 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10463 lib/Autom4te/Struct.pm:
10464 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10467 * doc/autoconf.texi (Special Shell Variables): Document some
10468 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10470 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10471 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10472 eval $LINENO is not portable in practice.
10474 2001-10-24 Akim Demaille <akim@epita.fr>
10476 * lib/Autom4te/General.pm (backname): New.
10478 2001-10-24 Akim Demaille <akim@epita.fr>
10480 * m4/: Remove, merged into...
10483 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10485 * doc/autoconf.texi (Shellology): Mention the problems with bash
10486 2.05's use of ANSI quoting in its `set' builtin.
10488 2001-10-22 Paul Eggert <eggert@twinsun.com>
10490 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10491 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10492 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10493 POSIX decided to standardize on the int flavor of strerror_r.
10494 Always do char* test, as there's no reason not to.
10495 Assign to a char* var, to catch strerror_r that returns int*.
10497 * doc/autoconf.texi (Particular Functions):
10498 Document the above changes. Also, document the fact that
10499 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10501 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10503 2001-10-20 Akim Demaille <akim@epita.fr>
10505 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10506 the executable was missing from the log.
10508 2001-10-20 Akim Demaille <akim@epita.fr>
10510 * lib/Autom4te/General.pm (&update_file): If destination is
10511 unchanged, remove the source.
10512 (&up_to_date_p): Don't be verbose, be debug.
10513 * bin/autoreconf.in: No longer support --m4dir.
10514 (&autoreconf): Display the full path of the configure.ac we are
10516 Trace it only once.
10517 Be sure to honor --force with gettextize.
10518 Always run aclocal.
10519 * doc/autoconf.texi: Adjust.
10521 2001-10-20 Akim Demaille <akim@epita.fr>
10523 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10525 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10526 `intl' is already present, as it refuses unless --force.
10527 (&parse_args): Use -I, --include instead of the old Autoconf
10529 ($localdir, $autoconf_dir): Remove.
10531 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10533 2001-10-19 Jens Petersen <petersen@redhat.com>
10535 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
10536 * doc/autoconf.texi (Particular Programs): Likewise.
10538 2001-10-19 Akim Demaille <akim@epita.fr>
10540 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
10541 file in @configure_input@.
10542 Don't mention `automatically' in addition to `generated'.
10543 * tests/torture.at (#define header templates): Adjust.
10545 2001-10-19 Akim Demaille <akim@epita.fr>
10547 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10548 comment, explain how to install automatic mode selection.
10551 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10553 * bin/autoreconf.in (autoreconf): Display the path to the
10554 configure.ac being studied.
10556 2001-10-18 Paul Eggert <eggert@twinsun.com>
10558 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10559 long, to work around a bug in the HP C compiler version HP92453-01
10562 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10563 (AS_BASENAME_EXPR): New macro.
10564 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10565 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10566 and fall back on 'sed' only if the other two fail. This makes
10567 AS_BASENAME act more like AS_DIRNAME.
10568 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10569 contains white space.
10570 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10571 Use AS_DIRNAME, since I think it's now DOS-friendly.
10572 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10573 Allow "dirname //FOO" to return either / or //, as POSIX allows
10576 2001-10-10 Akim Demaille <akim@epita.fr>
10578 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10579 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10582 2001-10-10 Akim Demaille <akim@epita.fr>
10584 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

11048 and is all that AC_FUNC_GETPGRP's users really need.
11050 2001-09-18 Akim Demaille <akim@epita.fr>
11052 * doc/autoconf.texi (Limitations of Make) <$<>: New.

11060 2001-09-18 Paul Wagland <paul@wagland.net>
11062 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11064 Add test for AS_BASENAME.
11065 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11066 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11067 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11068 * tests/base.at: Fixed the expected responses. The old ones were
11070 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11071 the documentation claims it should (and how it behaved in 2.13).
11073 2001-09-18 Akim Demaille <akim@epita.fr>
11075 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11076 the AC_CONFIG_COMMANDS invocation.
11077 This also solves the name clash problems.
11078 Don't set the package's ID.
11079 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11080 No longer to be shipped.
11081 (version.in): Remove.
11082 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11083 * lib/autoconf/status.m4: Adjust.
11084 Use `m4_PACKAGE_STRING'.
11085 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11086 the only optional argument is the name of the test suite.
11087 Expect `package.m4' to define the package signature.
11088 * lib/autom4te.in (Autotest): Add `package.m4?'.
11089 * tests/Makefile.am (package.m4): New.
11090 * tests/suite.at: ifnames is a victim.
11092 2001-09-18 Akim Demaille <akim@epita.fr>
11094 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11095 AC_LIBSOURCE, AC_CONFIG_FILES.

11103 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11104 Allow expression to return any value that can fit into unsigned long
11105 (not int, as before). Check for output errors.

11109 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11110 Always include <stdio.h> and <stdlib.h>. Evaluate
11111 the expression in an extra function before these includes. Call
11112 fprintf "%d" only after ensuring the argument is of type 'int'.
11113 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11115 2001-09-17 Paul Eggert <eggert@twinsun.com>
11117 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11118 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11119 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11120 when they don't exist.
11122 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11123 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11126 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11127 version with the version used by fileutils 4.1, except use
11128 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

11173 * lib/autotest/general.m4 (AT_INIT): Create and remove
11174 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11175 test suites can cohabit.
11177 2001-09-13 Akim Demaille <akim@epita.fr>
11179 * tests/mktests.sh: Don't output banners for empty test files.

11231 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11234 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

11278 to avoid GCC warnings.
11281 2001-09-05 Akim Demaille <akim@epita.fr>

11285 2001-09-05 Akim Demaille <akim@epita.fr>
11287 Be ready to handle filenames as stupid as `dnl.at', for if even
11288 the maintainer is dumb enough to do that...
11290 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11291 excellence in M4 quotation: consider `__file__' is active.
11293 And BTW, when invoking m4, pass the --include in the right order:
11296 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

11324 New, extracted from main.
11325 Use IO::File wherever possible.
11326 (input.m4): Be constant, use -I instead of hard coding $tmp.
11327 Therefore be a quoted heredoc.
11328 Don't invoke `_au_disable', since ac was not loaded, but just

11356 2001-08-31 Akim Demaille <akim@epita.fr>
11358 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11359 (testsuite Scripts): There is no such thing as `atconfig.in'.
11360 And actually one diagram is missing: test suite runtime.
11362 2001-08-31 Akim Demaille <akim@epita.fr>
11364 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11367 2001-08-31 Akim Demaille <akim@epita.fr>
11369 * bin/autoupdate.in (@include): `installcheck' revealed the path
11370 to m4sugar was lacking!
11372 2001-08-31 Akim Demaille <akim@epita.fr>
11374 * man/Makefile.am (.x.1): We really have to pass
11375 autom4te_perllibdir.

11379 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11380 debug scripts, in particular passing explicitly listed tests to

11385 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11386 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11387 Use directly autom4te, not autoconf.

11428 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11429 Drop AC_MACRODIR dead for real.
11430 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11431 `autoheader: `config.hin' is created'.
11432 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11434 2001-08-31 Akim Demaille <akim@epita.fr>
11436 * bin/autoheader.in: Rewrite in Perl.

11439 2001-08-31 Akim Demaille <akim@epita.fr>
11441 * bin/autoconf.in (--include, -I): New option.
11442 Map --localdir, --autoconf-dir onto it.
11443 Forward autom4te's options instead of interpreting them.
11444 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11445 There is no such envvar since the inception of autom4te.cfg.
11446 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11447 * bin/autoupdate.in: Adjust, and perform more control.

11449 * tests/autoconf: Dittowise.
11451 2001-08-31 Akim Demaille <akim@epita.fr>

11458 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11460 2001-08-31 Akim Demaille <akim@epita.fr>

11463 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11464 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11465 installed peer executables, only PATH is allowed to resolve it.
11466 Pass `autoconf_dir' via options, not via invisible envvars.
11467 * lib/Autom4te/General.pm (&find_peer): Remove.
11468 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11469 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11470 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11471 find the executables for it.
11472 * tests/Makefile.am: Major cleanup. Too lazy to document...
11473 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11475 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11476 indeed related to running the test suite, while passing
11477 --autoconf-dir and others is related to running non installed
11478 Autoconf executables. So don't do that, leave it to...
11479 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11480 * tests/autoscan: New.
11481 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

11495 2001-08-29 Akim Demaille <akim@epita.fr>
11497 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11498 Suggested by Paul Eggert.
11500 2001-08-29 Akim Demaille <akim@epita.fr>
11502 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11503 download in a tmp dir.
11505 2001-08-29 Akim Demaille <akim@epita.fr>
11507 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11508 case insensitive OSes out there :(

11513 * lib/autom4te.in: New.
11514 * lib/Makefile.am (edit, autom4te.cfg): New.
11515 * bin/autom4te.in (BEGIN): Simplify.

11972 * bin/autom4te.in (@m4_warning): New.
11973 (&handle_m4): Use it.
11974 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11975 warnings are issued at each run.
11976 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11977 is in the src tree.
11979 2001-08-15 Akim Demaille <akim@epita.fr>
11981 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11982 don't waste time running `autoupdate --version' works.
11983 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11985 2001-08-13 Akim Demaille <akim@epita.fr>

12001 duration of the test suite.
12003 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
12005 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
12006 endianness for comparison instead of relying on AT_CHECK_ENV.
12008 2001-08-11 Paul Eggert <eggert@twinsun.com>
12010 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
12011 to the INSTALL file.

12044 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12046 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12047 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12048 * doc/autoconf.texi (C Compiler Characteristics): Update
12049 documentation for AC_C_BIGENDIAN.
12051 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12053 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12054 magic values from an object file when cross-compiling.
12055 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12057 2001-08-10 Akim Demaille <akim@epita.fr>
12059 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12061 Suggested by Russ Allbery.
12063 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12065 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12066 current $prefix to the sub-configures.
12068 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12070 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12071 extension (needed on BeOS). Reported by Guido van Rossum.
12073 2001-08-09 Akim Demaille <akim@epita.fr>
12075 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12077 2001-08-07 Akim Demaille <akim@epita.fr>
12079 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12081 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12082 No need to remove the files before and after the each test, before
12083 each test and at the end of the suite is enough.
12084 Display only the children `times', not the shell's.
12085 If the test failed or was skipped, at-times is not available.
12087 2001-08-07 Akim Demaille <akim@epita.fr>
12089 Always produce testsuite.log, including when there are no
12090 failures. This helps getting information on skipped tests, and
12091 duration of the tests. Err, implement the latter btw.
12093 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12094 Dump information on the first run of each test.
12095 (AT_CLEANUP): Create `at-times' containing the duration of the
12098 2001-08-07 Akim Demaille <akim@epita.fr>
12100 The use of `dumpstat' revealed that `len' was used although it
12101 should not. m4_text_wrap was using it, but in the Autoconf world
12102 where it is legal. Hence (i) test M4sh in its own world, not
12103 Autoconf's, and (ii), ahem, fix the bug :)
12105 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12106 does not like `' instead of [].
12107 (AT_INIT): Forbid `^_?AT_'.
12108 And don't output such tokens.
12109 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12110 `script.as', and `autom4te.cache'.
12111 Remove `empty' and `macro' which are no longer used.
12112 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12113 * tests/m4sugar.at: Use it.
12114 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12116 2001-08-07 Akim Demaille <akim@epita.fr>
12118 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12120 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12122 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12124 2001-08-04 Akim Demaille <akim@epita.fr>
12126 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12127 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12129 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12130 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12131 (AC_F77_MAIN): Likewise.
12133 2001-08-04 Akim Demaille <akim@epita.fr>
12135 Don't rely on M4sugar outputting the patterns in files, since we
12136 might process the output _without_ running m4, hence without these
12139 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12140 * bin/autom4te.in (@Request::includes): Remove, unused.
12141 (@Request::source): Rename as...
12142 (@Request::input): this.
12143 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12144 (&handle_output): Fetch the patterns from the traces.
12145 `$forbidden' and `$allowed' are constant: use m//o.
12146 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12147 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12149 2001-08-04 Akim Demaille <akim@epita.fr>
12151 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12152 autoconf', i.e., in addition to caching traces, cache the output.
12154 * bin/autom4te.in (Request::cache): Rename as...
12155 (Request::id): this.
12156 ($cache, $icache, $tcache, $ocache): New.
12157 (&handle_m4): Save M4 output in the cache instead of $tmp.
12158 (&handle_output): Adjust.
12159 (&up_to_date_p): Check that the output cache is up to date too.
12160 (top level): Run `&handle_m4' iff force or the cache is invalid.
12161 Run `&handle_output' if the output cache is more recent.
12163 2001-08-04 Akim Demaille <akim@epita.fr>
12165 * bin/autom4te.in ($force): New.
12166 (&parse_args, &print_usage): -f, --force is a new option.
12167 (&handle_output): CPP directives might have spaces after `#'.
12168 (&parse_args): The first file only can be frozen.
12170 2001-08-04 Akim Demaille <akim@epita.fr>
12172 Don't let autom4te compute the `include' traces several times:
12173 first check that the trace cache file is up to date, and then
12174 compare its timestamp with that of the output.
12176 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12177 the preamble. Don't require 5.005 as Autom4te::General does it,
12178 and better yet (use `use', not `require'!).
12179 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12180 Class::Struct as Autom4te::Struct.
12181 * lib/Autom4te/General.pm (File::stat): Use it.
12182 (&mtime): New, export it.
12183 * bin/autom4te.in: Use it.
12184 Declare `$req' is invalid if it is outdated.
12185 Don't declare it valid before saving it if something went wrong.
12187 2001-08-04 Akim Demaille <akim@epita.fr>
12189 Autom4te shall not encode Autoconf data, and preselecting traces
12190 must be proposed to the users.
12192 * bin/autom4te.in (@required_trace): Remove.
12194 (&parse_args, &print_usage): -p, --preselect is a new option.
12195 (&up_to_date_p): Adjust.
12196 * bin/autoconf.in: Preselect some Autoconf macros.
12198 2001-08-04 Akim Demaille <akim@epita.fr>
12200 * tests/tools.at (autoconf --trace: user macros): Check traces on
12201 macros invoked without arguments, and macros invoked with multiple
12204 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12206 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12209 2001-08-03 Akim Demaille <akim@epita.fr>
12211 * bin/autoconf.in ($@): Work around the usual sh bug.
12214 2001-08-03 Akim Demaille <akim@epita.fr>
12216 Clean up the handling of the M4 builtins tracing exception.
12218 * bin/autom4te.in (Request::request): Don't complete M4 builtins

12221 (@m4_builtin): this.
12222 (%m4_builtin_alternate_name): New.
12223 (&parse_args): Complete the trace requests with alternate names.

12230 m4_if, and m4_wrap.

12234 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12235 (m4_divert_pop): Dump the whole diversion stack when a diversion
12237 * bin/autom4te.in (&handle_output): Remember of the first
12238 occurrence of a possibly undefined macro, not the last.
12239 Complain about the possibly undefined macros in the same order as
12240 the appear in the output.
12241 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12242 * tests/tools.at (autoconf: forbidden tokens, basic)
12243 (autoconf: forbidden tokens, exceptions): No longer sort
12244 autoconf's stderr, as it is now deterministic.
12245 Check that `dnl' is caught.
12247 2001-08-01 Akim Demaille <akim@epita.fr>
12249 * configure.ac: Bump to 2.52c.

12266 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12267 `END', as `Autom4te::General::END' will be triggered.
12268 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12269 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
12270 system to run `mv', `rm', and `cmp'.
12272 2001-08-01 Akim Demaille <akim@epita.fr>
12274 * lib/Autom4te/General.pm (&unique): New.
12275 * bin/autoscan.in (&output): Use it to issue trace requests once.
