8 * doc/autoconf.texi (Installation Directory Variables):
9 Drop extra @samp from `@table @samp' item.
10 (Limitations of Usual Tools): Comment fix.
11 Do not nest @samp just to point to other table items.
12 (Writing testsuite.at) <AT_CHECK>: The second argument to
13 `@dvar' is already @samp'ed.
14 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
15 do not use @var in the second argument.
17 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
19 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
20 $as_shell.exe too. Problem reported by Andreas Buening in
21 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
23 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

32 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
33 case the compiler dumps core. Problem reported for
34 OpenServer 5.0.7 by Tim Rice in
35 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

59 * configure.ac (AC_INIT): Bump to 2.59e.
62 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
66 * config/texinfo.tex: Sync from upstream.
68 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
69 seen, invoke libtoolize with `--ltdl' argument.
70 * lib/autom4te.in (Autoreconf-preselections): Adjust.
72 Suggested by Eric Blake.
74 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
76 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
77 reported by Ralf Wildenhues.

90 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
91 message issued by AC_REQUIRE.
92 * tests/m4sugar.at: Check m4_require's error message.
93 * tests/base.at: Check AC_REQUIRE's error message.
94 * tests/local.at (AT_CHECK_M4): New macro, almost identical
96 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
98 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
99 `expout' as the last parameter.
100 * tests/tools.at: Adapt to the above change.
102 2006-06-04 Stepan Kasal <kasal@ucw.cz>
104 * doc/autoconf.texi (Limitations of Usual Tools): Correct
105 information about race-free implementations of mkdir.

114 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
116 * NEWS: GNU make now recommended for VPATH builds.
117 Mention that some macros are now documented to be obsolescent.
119 Prefer "current" to "modern" to describe
120 currently-used (albeit perhaps old-fashioned) hosts.
121 Mention which ancient features no longer need to be worried about.
122 setgid -> set-group-ID
123 setuid -> set-user-ID (these are the Posix terms)
124 Fix some misuses of "only".
125 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
126 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

132 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
133 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
134 Mention that these macros are obsolescent.
135 (Installation Directory Variables): shall -> should
136 (File Descriptors): Mention that 0, 1, 2 might get reopened.
137 Mention that it's now safe to use 3 and 4.
138 (Limitations of Usual Tools): cp -r is now specified by Posix.
139 Omit longwinded and obsolescent discussion of cp -f.
140 Modernize discussion of expr, ls.
141 (Limitations of Make): Modernize discussion of VPATH builds.
142 Mention $? as a workaround in some cases.
143 * doc/install.texi (Basic Installation):
144 Mention "./configure; make; make install" first. Be more
145 specific about why this file is generic. Remove unnecessary
146 parens. Remove misleading "only". Remove obsolete advice
147 about csh. Don't say "configure" takes awhile; say it
148 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
149 and CC=c99 rather than CC=c89, as these are blessed by current
150 Posix. Recommend GNU make if doing a VPATH build.
152 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
154 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
155 examples involving shell prompts.
157 2006-06-02 Stepan Kasal <kasal@ucw.cz>
158 and Paul Eggert <eggert@cs.ucla.edu>
160 * doc/autoconf.texi (Here-Documents): Add details about the
161 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
162 use "here-documents" instead of "here documents".
164 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
166 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

171 anywhere in directory names.
173 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
175 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
176 about quoting the case statement, just in case.
177 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
178 was fixed in ksh93g; reported by Ralf Wildenhues.
180 2006-05-31 Stepan Kasal <kasal@ucw.cz>
182 * doc/autoconf.texi (System Services): Do not document
183 overriding EXEEXT via ac_cv_exeext=ext.

192 argument with leading hyphen. Problem reported by Paul Eggert.
194 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
196 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
197 about quoting ac_try: quote all of it, if any of it seems suspicious.
198 This means we don't have to worry about ${ or sed any more.
199 Also, double-quote the case statement, to work around misuses via
200 underquoting as reported by Ralf Wildenhues in
201 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
202 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
203 undocumented and dangerous macro.
204 Problem reported by Ralf Wildenhues in

213 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
215 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
216 since evidently some packages rely on the old, broken behavior.
217 Problem reported by Ralf Wildenhues in
218 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
219 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
220 pre-2006-05-26 definitions, but leave in the comments that
221 these macros are dangerous and should not be used.
222 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
223 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
224 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
225 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
226 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
228 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
230 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
231 the use of 'tr', since this is our only use of 'tr'.
233 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
234 and Paul Eggert <eggert@cs.ucla.edu>
236 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
237 Don't assume 'grep' works on long lines, since AIX grep doesn't.
239 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
241 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
242 the output file in the `${datarootdir}' test.
244 2005-05-28 Stepan Kasal <kasal@ucw.cz>
245 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
247 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
248 mention of `datarootdir' in the input file(s), but literal
249 `${datarootdir}' in the output file, and we haven't warned yet,
250 then warn as well: the user may have (erroneously) used
251 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
252 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
253 * tests/torture.at (datarootdir workaround): Extend this test.
256 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
257 and Paul Eggert <eggert@cs.ucla.edu>
259 * doc/autoconf.texi (autoheader Invocation): The first argument to
260 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
261 alternatives and clear up the language a bit.
263 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
265 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
266 ac_config_guess, ac_config_sub, ac_configure.
267 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
268 Fix typo that prevented an unnecessary space from being removed.
269 Problems reported by Ralf Wildenhues in:
270 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
272 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
274 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
275 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
276 Don't use the term "thread-safe" to talk about mkdir race
277 conditions, since the problem is more a process than a thread
278 issue. Problem reported by Stepan Kasal in:
279 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
280 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
281 the test for 'install' more closely. Look at MKDIR_P first.
282 Look in the PATH, and at /opt/sfw/bin.
283 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
284 Don't bother to try mkdir -p, since we already check mkdir --version;
285 just look at the version number. (There's no easy way to check
286 for race-free implementations.)
287 * tests/tools.at (autoconf: subdirectories): Adjust to above
288 changes, since MKDIR_P now might end in "/mkdir -p".
290 * doc/autoconf.texi (autoheader Invocation): Mention that the
291 first arg of AC_DEFINE_UNQUOTED must be a literal.
292 Problem reported by Ben Pfaff in
293 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
295 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
296 * doc/autoconf.texi (Special Chars in Variables): New section.
297 (Preset Output Variables): Warn about special chars in CPPFLAGS.
298 (Installation Directory Variables): Quote $(datadir) better.
299 (Limitations of Builtins): Describe some of eval's trickiness.
301 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
302 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
303 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
304 in front of every arg, not just trailing args. Quote apostrophes.
305 (_AC_EVAL_ECHO): New macro.
306 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
307 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
309 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
310 exposed by quoting of eval argument. Put the command on line line
312 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
313 (_AC_PATH_X, AC_PATH_X): Quote more safely.
314 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
315 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
316 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
317 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
318 Use eval more safely.
319 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
320 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
322 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
323 lines, exposed by quoting of eval argument.
325 2006-05-26 Stepan Kasal <kasal@ucw.cz>
326 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
328 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
329 initialization of `ac_cv_exeext', do not override it if it was
330 already set, unless it was set to `no', for compatibility with
331 Autoconf-2.13, and comment this.
332 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
333 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
334 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
335 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
336 Document that this test may be overridden by setting
339 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
341 Revert these two patches:
343 2006-04-06 Eric Blake <ebb9@byu.net>
344 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
345 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
348 2006-04-01 Stepan Kasal <kasal@ucw.cz>
349 Clean up _AC_COMPILER_EXEEXT* macros.
350 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
351 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
352 ac_file to the name of the default output file and call
353 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
354 initial `rm' of the candidate files...
355 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
356 the same list in subsequent `rm' calls, and for the temporary
357 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
358 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
359 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
360 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
361 no longer needed) by libtool. Make it a cache check.
362 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
363 copied here by mistake.
364 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
366 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
367 _AC_COMPILER_OBJEXT directly.
368 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
370 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
372 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
373 Fix description of how the buggy `sed' works.
375 2006-05-25 Noah Misch <noah@cs.caltech.edu>
379 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
380 ENOLCK. Only mention `make -j' when applicable. Only raise
381 fatal errors when `make -j' is involved. Improve error message.
383 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
385 * doc/autoconf.texi (Here-Documents): We now know more about
386 the variable expansion in here documents bug.
387 Thanks to Tim Rice and Stepan Kasal.
389 * doc/autoconf.texi (Making testsuite Scripts): Add an example
390 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
392 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
394 * tests/autotest.at (Multiline command from M4 expansion):
395 No failure to be expected if the shell quotes newlines in
396 commands in the `set -x' output. Report by Tim Rice.
399 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
401 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
402 expansion in the here-documents used by config.status, as that
403 runs afoul of the Korn shell version M-12/28/93d bug described in
404 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
405 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
406 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
408 2006-05-23 Jim Meyering <jim@meyering.net>
410 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
411 Fix typo introduced with 2006-04-02 change. It reversed the sense
414 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
416 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
417 ac_dB slightly, to save bytes in the script.
418 Max out at 50 lines, rather than 96; this is more likely
419 (though not guaranteed) to avoid obscure 'sed' failures.
421 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
423 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
424 `tr -d -' as bad option argument. Work around this by deleting
425 an unrelated character.
426 Report by Tim Rice <tim@multitalents.net>.
428 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
429 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
430 Stepan Kasal <kasal@ucw.cz>
432 * doc/autoconf.texi (Particular Programs): Do not promise that
433 we always prefer the GNU version of the program, and that we
434 search according to PATH; both rules can have exceptions.
435 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
436 AC_PROG_SED. Move descriptions of limitations
437 to the Limitations of Usual Tools section.
438 (Limitations of Usual Tools) <sed>: Mention script length
439 limitations with Solaris /usr/ucb/sed.
440 <grep>: Fix wording for empty alternative. Mention that -c and
441 -l should not be combined, and that -E and -F should not be
444 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
445 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
447 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
448 limits in Solaris 8 /usr/ucb/sed by testing a long script.
450 2006-05-22 Stepan Kasal <kasal@ucw.cz>
452 * doc/autoconf.texi (Defining Symbols): Literal parameter of
453 AC_DEFINE is now passed to m4_pattern_allow.
454 * NEWS: Mention that; likewise for AC_SUBST.
455 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
456 the parameter to m4_pattern_allow.
457 * tests/tools.at: Add a check for that.
459 2006-05-22 Stepan Kasal <kasal@ucw.cz>

466 only the files that this macro generates.
468 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
470 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
471 the HP-UX sed limitation of 99 commands, labels do not count.
472 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
474 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
476 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
478 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
479 Import the following fix from coreutils:
481 2006-01-13 Jim Meyering <jim@meyering.net>
483 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
484 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
485 not double-quote uses of that variable, to accommodate the rare
486 case in which getmntent is available in none of the libraries
487 checked. This happens at least on FreeBSD 5.0.
489 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
491 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
492 ac_config_guess, ac_config_sub, and ac_configure, since evidently
493 some other programs unwisely rely on these undocumented vars.
494 But put in warning comments about them.
495 Problem reported by Ralf Wildenhues in
496 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
497 * NEWS: Document that these variables are intended to go away.

501 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
502 and set the language to C++ (analogous to the equivalent Fortran
505 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
506 * doc/autoconf.texi (C++ Compiler): Document it.
507 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
510 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
512 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
513 that caused config.status to generate 100-command sed scripts; the
514 portable limit is 99.
516 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
518 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
519 variable `ac_d' instead of `d' to avoid infringing namespace.
520 Report by Ralf Menzel.
522 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
524 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
525 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
526 * tests/tools.at (autoconf: subdirectories): New test, taken from
527 the corresponding problem report by Ralf Wildenhues in:
528 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
530 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
531 Quote some uses of shell variables if they might suffer unexpected
532 globbing. This doesn't fix all instances of quoting problems that
533 I found, just the easy ones that look safe.
534 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
535 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
536 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
537 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.

540 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
542 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
543 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
545 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
547 * bin/autoreconf.in ($help): Reword according to the manual.
548 Suggested by Olly Betts.
550 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
551 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
553 * bin/autoreconf.in: Pass the directory argument to
554 `require_configure_ac'. Fix comment.
555 * tests/torture.at (Configuring subdirectories): Expose this.
556 Reported by Olly Betts.
558 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
560 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
561 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
564 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
565 `$configure_in' instead of `configure.in', to preserve
568 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
570 * config/config.guess, config/config.sub, config/texinfo.tex,
571 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
573 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
575 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
576 test for C99 conformance; (bool) 0.5 is an integer constant
577 expression, but (bool) -0.5 is not. Problem reported by Fedor
578 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
580 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
582 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
583 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
584 Warn about obsolete install-sh files. Remove stray sentence
585 fragment and fix cross reference.
586 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
587 install -d; this undoes the 2006-05-10 change.
588 (MKDIR_P): Mark with AN_MAKEVAR.
589 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
590 that we don't require $INSTALL to be thread-safe. Move comments
591 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
592 of AC_PROG_INSTALL. Output a message saying that we're checking
593 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
594 MKDIR_P instead of AC_SUBST.
595 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
596 Special magic for MKDIR_P, too.
597 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
599 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
601 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
603 Sync from Automake, as follows:
605 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
606 * config/install-sh: Initialize IFS, so field splitting isn't
608 * config/mkinstalldirs: Likewise.
609 * config/missing: Remove superfluous quotes. Replace all uses of
610 `[' by `test', for consistency, and for..
611 * config/missing (sed_minuso, sed_output): New variables.
612 (autom4te, help2man, makeinfo): Use them. Unifies detection of
613 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
614 Fixes `missing' to detect `--output' for help2man. Fixes
615 PR automake/483. Report by Dennis J. Linse.
616 (autom4te): Document in `missing --help'.
618 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
620 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
621 * config/install-sh: Don't use 'path' to talk about file names,
622 as per GNU coding standards. Close a race condition reported by Ralf
623 Wildenhues and Stepan Kasal. There is still a race condition
624 on hosts that predate Posix 1003.1-1992, but we can't help this.
625 Don't mishandle weird characters like space on pre-Posix hosts.
626 Invoke mkdir at most once per dir arg on pre-Posix hosts.
627 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
628 AC_PROG_MKDIR_P from AS_MKDIR_P.
629 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
630 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
631 earlier editions are not (including Automake 1.8.3).
632 Do not suggest mkinstalldirs for thread-safety.
633 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
634 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
635 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
636 presence of special characters and race conditions.
637 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
638 in Autoconf's name space.
640 2006-05-10 Bruno Haible <bruno@clisp.org>
641 and Paul Eggert <eggert@cs.ucla.edu>
643 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
644 from Automake with minor changes.
645 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
647 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
649 * config/install-sh: Update to Automake CVS version, as follows:
650 2006-04-25 Stepan Kasal <kasal@ucw.cz>
651 * lib/install-sh: Simplify the expr implementation of dirname.
652 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
653 * lib/install-sh: Handle --, and diagnose unknown options.
655 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
657 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
658 `./autom4te' to create `./testsuite', since the `all' target
659 will ensure its presence, but `installcheck' should not create
660 the uninstalled wrappers.
662 * tests/torture.at (Unusual Automake input files): Skip if we
663 detect automake < 1.8.
665 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
667 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
668 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
669 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
672 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
674 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
675 munge (multiple) white space and other oddities.
676 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
677 single quotes in variable assignment.
678 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
679 and similar failures by adding multiple spaces, tabs, and other
681 Report and different test suggested by Francesco Romani
682 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
684 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
685 single quotes, we only need to search for single quotes; this
686 both simplifies the search pattern, and makes us less
687 susceptible to `echo' variations for arguments not containing
689 (_AC_ARG_VAR_VALIDATE): Likewise.
691 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
693 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
694 `$*' and IFS concatenation issue with traditional shells and
695 bash-2.04. Report by Seanster@Seanster.com.

707 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
708 and Bruno Haible <bruno@clisp.org>
710 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
712 (Integer Overflow): Mention the special case of integer division
715 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
717 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
718 traditional shells like the Solaris one that do not use the
719 first IFS character for assembling `$*'.
720 Prompted by a related report from autoconf_bug@nro.ca.
722 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
723 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

734 in URLs to improve DVI formatted output (requires texinfo 4.6).
735 (System Services, Systemology, Shellology): Likewise.
736 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
739 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
741 (Runtime): Fix macro argument names to match description:
742 `action-if-found' -> `action-if-true' and similarly.
743 (Obsolete Macros): Likewise.
744 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
745 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
746 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
748 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
750 * doc/autoconf.texi (Limitations of Make): Clean up markup.
753 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
756 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
758 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
759 /bin/sh set unsorted output.
760 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
761 * tests/local.at: Likewise.
763 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
765 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
766 (Integer Overflow, Null Pointers, Buffer Overruns):
767 (Floating Point Portability, Exiting Portably): New sections.

778 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
780 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
781 since as_me isn't set yet.
783 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
785 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
786 a few minor bugs in this area.
788 * doc/autoconf.texi (Programming in M4sh): Comment out the
789 documentation of AS_BASENAME, for now.
790 (Shell Substitutions): Do not use AS_DIRNAME in an example.
791 (Limitations of Builtins) <basename>: Do not refer to
793 * bin/autoconf.as (me): Don't use AS_BASENAME.
794 (dir): Remove the unused variable.
795 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
796 AS_DETECT_REQUIRED. All uses changed.

809 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
811 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
812 of "run time" and "run-time" changed to "runtime", for consistency.
813 * lib/autoconf/fortran.m4: Likewise (in comment).
814 * lib/autoconf/functions.m4: Likewise.
815 * lib/autoconf/general.m4: Likewise.
816 * lib/autoconf/headers.m4: Likewise.
818 * doc/autoconf.texi (Run Time): Document the exit status situation
819 with more accuracy and detail.
821 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
823 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
824 Archive is not officially `GNU' any more. Update URL.

830 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
831 newline from the `trap' code to finish `config.log'; the NetBSD
832 /bin/sh resets the exit status after an empty command, as
833 documented in doc/autoconf.texi.
834 Reported by Dalibor Topic <robilad@kaffe.org>.
836 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
838 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
839 Suggested by Bruno Haible.
841 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
843 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
844 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
845 Instead, just list the shells that we know work.
846 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
847 changed. Be more cautious about the _cv_ variable.
848 * tests/tools.at (Syntax of the shell scripts): Check the
849 _cv_ variable once, at first, to avoid an internal autoconf error
850 when sh -n does not work.
852 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
854 * lib/Autom4te/FileUtils.pm: Sync from Automake.
856 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
858 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
859 use ">&-" since we're only 99.999% sure that this is portable,
860 and since the MinGW bug is fixed in a different way.
861 * lib/autotest/general.m4 (AT_INIT): Likewise.
863 2006-04-16 Stepan Kasal <kasal@ucw.cz>
865 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
866 before opening config.log, to avoid hitting a bug on MinGW.
868 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
870 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
871 AS_MESSAGE_LOG_FD before reopening it onto the log file.
872 This works around a MinGW bug reported by Eric Paire.
873 Make sure that all writes to the log file append to it,
874 rather than possibly losing data.
875 * lib/autotest/general.m4 (AT_INIT): Likewise.
877 2006-04-14 Stepan Kasal <kasal@ucw.cz>
879 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
882 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
886 * configure.ac (AC_INIT): Bump to 2.59d.
888 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
892 * Makefile.maint (news-date-check): Do not require a leading `*'
893 before the release date in NEWS.
895 2006-04-12 Stepan Kasal <kasal@ucw.cz>
896 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
898 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
899 the instantiated file do not contain the string 'datarootdir'
900 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
901 @mandir@, replace the reference '${datarootdir}' by the value.
902 * tests/torture.at (datarootdir workaround): New test.
903 * NEWS: Advertise this temporary fixup.
904 Based on a patch by Bruno Haible, reported and analyzed by
905 Paul Eggert and Noah Misch.
907 2006-04-12 Eric Blake <ebb9@byu.net>
909 * tests/autotest.at (Debugging a failed test): Fix comment.

913 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
914 all the changes since 2006-04-07.
916 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
918 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
919 succeeded, but `ln -s file dir' failed, take care to remove the
920 leftover target before the next test, to prevent its spurious
921 failure; also make sure `ln file dir' works before selecting it.
922 Thanks to Keith Marshall for pointing this out.
925 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
926 assignments in `at_debug_args', so that we put them correctly
928 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
929 Reported by Eric Blake.
931 2006-04-11 Eric Blake <ebb9@byu.net>
933 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
934 top-level tests after micro-suite has been run. Used in...
935 (Debugging a successful test, Debugging script and environment),
936 (Debugging a failed test): ...these new tests. The first of these
938 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
939 macro, split out from...
940 (AT_INIT): ...here, so that using -d also generates a run script.
941 Document that -d inhibits top-level logging.
942 * doc/autoconf.texi (testsuite Invocation): Document that -d only
943 inhibits top-level logging; debug scripts are created.
945 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
947 * tests/autotest.at (Empty test, Empty check): New test to check it.
949 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
952 2006-04-10 Stepan Kasal <kasal@ucw.cz>
954 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
955 the files if a problem appears. Make the empty *.at files
956 read-only, too. Proposed by Ralf Wildenhues.
958 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
960 * config/Makefile.am: Add comment to force updated Makefile.in.
962 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
963 space only patch to this file, this patch causes the Makefile.in
964 files that include freeze.mk to be updated, and thus have a
965 newer time stamp again, which in turn makes a pristine CVS
966 checkout have correct time stamps.
968 * Makefile.maint (cvs-sv): New macro, to be used..
969 (config.guess-url_prefix, config.sub-url_prefix)
970 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
971 point to CVS text checkout of Gnulib files.
972 (copyright-check): Bump current year.
973 (announcement): Do not hard-wire `./announce-gen'.
974 (cvs-update): Propagate failures of `cvs' and `move-if-change'
976 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
978 (wget_files): Update config.guess, config.sub, texinfo.tex by
979 `wget-update', now that their URLs work again.
981 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
983 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
984 Problem noted by Paul D. Smith.
986 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
988 * doc/autoconf.texi: Remove unused words from word list.
989 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
990 .x-sc_trailing_space: New files.
992 * doc/standards.texi: Sync from gnulib.
994 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
995 `LIBOBJDIR' as experimental.
997 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
998 with a target directory; it's internally implemented as `cp'
999 anyway, but since Autoconf advertises the possibility to use
1000 a target directory when LN_S is `ln -s', we need to find out.
1001 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1002 analyzed by Keith Marshall <keith.marshall@total.com>.
1006 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1008 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1009 confdefs.h as-is. In general, if it has backslash-newline or the
1010 like, then it doesn't work either to sort or to remove empty
1013 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1015 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1017 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1019 * lib/autom4te.in (Automake-preselections): Preselect
1022 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1024 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1025 apostrophe within a single-quoted string, as this is the usual
1026 tradition and is easier to read than '"'"'. Don't rely on the
1027 shell treating "$/" like '$/'. Use a more-consistent indenting
1030 2006-04-09 Eric Blake <ebb9@byu.net>
1032 * tests/autotest.at (Backquote command substitution),
1033 (Multiline backquote command substitution): Remove mistaken
1034 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1036 (Parenthetical command substitution, Multiline parenthetical
1037 command substitution): here.
1039 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

1072 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1073 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1074 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

1103 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1104 of the warning introduced by the 2001-08-28 change.

1114 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1116 Revert the patch from 2006-04-01 and only improve
1117 _AS_DETECT_BETTER_SHELL:
1119 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1120 skip nonexistent directories.
1121 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1122 only shell candidates which exist.
1123 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1124 * lib/autotest/general.m4 (AT_INIT): No need to give three
1125 parameters to _AS_PATH_WALK.
1127 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1128 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1130 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1131 distinguish m4sugar macros.
1132 * tests/tools.at (autoupdating with aclocal and m4_include):
1133 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1134 test case by Noah Misch <noah@cs.caltech.edu>.
1136 2006-04-07 Stepan Kasal <kasal@ucw.cz>

1139 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1141 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

1147 * doc/autoconf.texi (Programming in M4sh): Document that
1148 AS_MKDIR_P exits the script on failure.
1149 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1151 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1153 * config/elisp-comp, config/install-sh, config/mdate-sh,

1169 Paul Eggert <eggert@cs.ucla.edu>,
1170 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1172 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1173 whether `set' quotes correctly: redirect stderr of the tested
1174 `set', and use a subshell, for Ultrix; use `sed' instead of
1175 `grep' for zsh `set' which may write binary output; match only
1176 at the beginning of a line, to avoid false positives.
1177 In order to avoid false positives by unrelated variables with
1178 multiline content, put the dump algorithm in a subshell and
1179 unset all variables containing newlines (except some which are
1180 special to the shell). Warn about cache variables that are
1183 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1225 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1226 ac_config_<foo>s again, sometimes normalized, sometimes not.
1227 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1228 (AC_CONFIG_COMMANDS): Do not do so here.
1229 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1230 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1231 2005-07-25 rewrite. Noticed by Noah Misch.
1233 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1234 _AC_PRESERVE_HELP_ORDER, ...
1235 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1237 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1238 inside m4_expand_once; it is redundant.
1240 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1241 for --help from Cygnus `configure.'
1243 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1256 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1257 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1258 * doc/autoconf.texi (Help Formatting): New node.
1259 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1261 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1263 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1264 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1265 lib/autoconf/types.m4, lib/autotest/general.m4,

1282 TAGS to ac_config_<foo>s.
1283 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1284 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1285 normalizing it, consistent it with previous releases.
1286 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1288 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1290 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1291 Use simplified args that Eric Blake originally suggested.
1293 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1295 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1296 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1297 Use 'comm' rather than N instances of grep; this also fixes a bug
1298 whereby substrings were incorrectly matched, causing us to not
1299 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1300 (exclude_list): Exclude empty macros.
1301 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

1323 * tests/mktests.sh: Update copyright year in the header of the
1326 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
1327 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
1328 typedef'ed restricted pointer, to catch a compiler bug on
1329 HP-UX 11.x, and fix warnings so it passes with -Werror.
1330 (_AC_PROG_CC_C99): Likewise.
1331 Reported by Albert Chin <china@thewrittenword.com>.

1345 2006-04-03 Eric Blake <ebb9@byu.net>

1351 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1352 to log, point to testsuite output tree.
1354 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
1356 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
1357 * doc/autoconf.texi (Function Portability): Mention that C++
1358 has trouble with 'exit'.
1359 (Guidelines): Test programs shouldn't use 'exit'.
1360 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
1361 Remove; all uses removed.
1362 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

1380 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1382 Clean up _AC_COMPILER_EXEEXT* macros.
1384 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1385 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1386 ac_file to the name of the default output file and call
1387 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1388 initial `rm' of the candidate files...
1389 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1390 the same list in subsequent `rm' calls, and for the temporary
1391 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1392 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1393 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1394 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1395 no longer needed) by libtool. Make it a cache check.
1396 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1397 copied here by mistake.
1398 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1399 _AC_COMPILER_EXEEXT.

2173 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2174 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2175 by the function rather than ignoring it.
2176 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2177 comparing its address. Intel's interprocedural optimization was

2229 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2231 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2232 calls, so that the final expansion of this macro is shorter.
2233 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2234 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2235 the cleanup there. Use AS_VAR_* macros, to be more general.
2236 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2238 * lib/autoconf/general.m4: Use AS_IF where appropriate.

2265 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2266 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

2287 Update limitations about when to call AC_CONFIG_HEADERS.
2288 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2289 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2290 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2291 ``Configuration Actions''; fix their index entries.
2293 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2294 options correctly. Process N-M as M-N if M is smaller than N.
2295 Process ranges correctly so that N-N will run only N.
2296 Sort and uniquify the tests that will be run. If there is more
2297 than one test, reinsert the banners for the tests.

2303 before passing the macro name to AH_TEMPLATE.
2305 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status

2328 When building in place, set srcdir="."; suggested by Tim Van Holder.
2330 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2331 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...

2350 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2352 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

2366 "<tab>" in comment, so that the point is understandable.
2368 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2370 Rewrite substantial part of lib/autoconf/status.m4.
2371 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2372 and CONFIG_COMMANDS are not processed in four separate loops.
2373 Instead, there is one main loop. This alows that the common code
2374 is expanded only once, thus config.status (and configure) is smaller.
2376 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2377 the AC_LIST_FILES and cousins macros are no longer used.
2379 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2380 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2381 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2382 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2383 contain the initialization, nor the for loop, nor the associated
2384 commands; all these go to ...
2385 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2386 _AC_OUTPUT_CONFIG_STATUS.
2387 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2388 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2389 (_AC_OUTPUT_FILE): The creation of the sed script ...
2390 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2391 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2392 _AC_OUTPUT_MAIN_LOOP.
2393 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2394 _AC_CONFIG_COMMANDS): Use ...
2395 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2396 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2397 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2398 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2399 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2400 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2402 (_AC_CONFIG_UNIQUE): Update.
2403 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2404 Replaced by this ...
2405 (_AC_LIST_TAGS): ... new common macro.
2406 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2407 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2408 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2409 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2410 this didn't belong to the `config commands' section.
2411 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2412 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2413 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2414 to the `config commands' section either.
2415 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2416 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2418 ... and many changes to the comments nearby.
2420 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2421 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2422 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2423 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2424 (#define header templates): The comment at the top of the generated
2425 header now includes the name(s) of the source file(s).
2427 Several unrelated small changes:
2429 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2430 parameter to AC_DIAGNOSE.
2431 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2432 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2433 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2434 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2436 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2437 in AC_OUTPUT doesn't double-quote it either.
2438 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the

2443 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2444 versions of Portland Group compiler produce single- and double-quoted
2445 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>

2448 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2450 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.

2459 ac_cv_build_alias to ac_build_alias.
2460 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2462 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2463 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2464 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2465 (AC_ARG_VAR): ... here.
2466 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2469 Keep a list of all precious variables and process them with one simple
2470 for loop, instead of expanding all commands, or, OTOH, complicated
2471 processing of output of "set".
2472 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2473 variable names in new macro...
2474 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2475 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2476 a loop to assign all ac_env_* and ac_cv_env_* variables.
2477 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2479 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2480 its value to shell variable ac_precious_vars and call
2481 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2482 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2483 _AC_ARG_VAR_VALIDATE.

2503 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2504 They are generated by the Tru64 v5.1B shell.

2513 Fix cases when the varsions of Autoconf and Autotest don't match.
2514 Reported by Noah Misch.

2516 at_top_builddir, for compatibility with older autotest.
2517 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2518 is not set, use at_top_builddir, for compatibility with older
2519 versions of autoconf.
2521 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2523 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2524 Problem reported by Patrick Welche.
2526 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2528 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2529 sed substitution command, so that we allow | in program prefixes
2530 and program suffixes. (& is a problem anyway; we're not fixing
2532 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2533 configure_input, top_builddir, srcdir, etc.
2534 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2535 PATH_SEPARATOR in AUTOTEST_PATH.
2537 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

2545 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

2570 Likewise for --header; moreover, recognize --he and --h as shortcuts
2571 for --help in that case.
2573 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2574 matches the order of execution. No code changed.

2596 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2597 (AC_SUBST): Call it.
2598 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2599 the directory specific variables; but don't call it for configure_input.
2601 2005-06-28 Derek Price <derek@ximbiot.com>
2603 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2606 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2608 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

2625 from Justace Clutter.
2626 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2627 variable into diagnostic. Make the diagnostic an error, not a warning,
2628 because we really don't support spaces and suchlike in dir names.
2629 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2630 Don't worry about backslashes in srcdir; it can't happen now.

2641 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
2643 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
2644 that '\|' is not allowed in BREs; recommend using newline separated

2657 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2658 b, t, r, w commands require single space, while : cannot have any.
2659 (Special Shell Variables): Fix sed code this in the example.
2660 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2661 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

2673 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2674 * doc/autoconf.texi:
2675 Don't mention Solaris versions so much, if a
2676 problem is common to all extant versions of Solaris. Say "SunOS
2677 4" instead of "SunOS" for SunOS 4.
2678 (awk): Mention more of the limitations of traditional Awk.
2679 (cat): Don't talk about cat -v.

2695 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2697 * doc/autoconf.texi: "filesystem" -> "file system".
2698 "behaviour" -> "behavior".

2704 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
2706 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.

2719 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2721 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2722 -u, since it outputs chatter if the input files are the same.
2723 Problem reported by Ralf Menzel.
2725 2005-06-08 Derek Price <derek@ximbiot.com>
2727 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2728 renaming them since they are about to be redefined anyhow.
2730 2005-06-08 Derek Price <derek@ximbiot.com>
2732 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2733 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2734 Move m4_undefine to alphabetical order.
2736 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2738 * README: Recommend GNU M4 1.4.3 or later.
2739 * doc/autoconf.texi (Introduction): Likewise.
2740 Reword to avoid some formatting glitches.
2741 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2742 Clarify explanation of HP compiler bug.
2743 Redo example output tp match current CVS snapshot.
2744 Use @example.org in email addresses when the examples
2745 might get inadvertently cut-and-pasted into user code.
2746 Remove example of autom4te usage that doesn't seem to work now.
2747 Use modern AC_INIT (except when the example is meant to be
2748 shown with Autoconf 2.13).
2749 Update ksh info for Solaris 9 and later.
2751 Modernize description of Automake versions a bit.
2752 Don't claim a future version of Autoconf is near.

2762 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2763 Tru64 ksh pattern matching bug. Reported against Libtool by
2764 Albert Chin <libtool@mlists.thewrittenword.com> and
2765 Nicolas Joly <njoly@pasteur.fr>.
2767 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2769 m4_cdr of one-member list was [[]] (one-member list containing an
2770 empty string) instead of [] (an empty list. Callers were skewed to
2771 match this misbehaviour. As a consequence of this:
2772 - m4_foreach([x], [], [foo]) expanded to `foo', while
2773 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2774 This bug has been fixed:
2776 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2777 expand to an empty string; print error msg if called without
2779 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2780 misbehaviour; handle [] and [[]] correctly.
2782 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2784 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
2785 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
2786 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2788 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2790 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2791 swallow records with more than 99 fields.
2792 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2793 parse the long line.
2795 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2797 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2798 swallow literals longer than 399. Reported by Ralf Wildenhues.
2799 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2800 to workaround this limitation.
2802 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2804 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2805 to gfortran, and make these the first two compiler names
2806 checked (following the general autoconf preference for gcc).
2808 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2810 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2811 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2812 (testsuite): Make sure autotest.m4f is up-to-date before using it.
2814 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
2816 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2817 expression of unbounded size when processing the --list
2818 option. This runs afoul of a limit of 399 bytes per regular
2819 expression on AIX. Problem reported by Ralf Wildenhues.
2821 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
2823 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
2824 * doc/autoconf.texi (Particular Headers): Reword example
2825 for multiline stdbool replacement.
2826 (Setting Output Variables): Reword text a bit. Don't
2827 give all the details about |#_!!_#|.
2828 Reword description of line replacement.
2830 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2832 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2833 now contain newlines, and substituted files must be referenced on
2834 a line alone; the sed scripts to substitute them are now very
2836 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2837 commands can be put in a sed script portably.
2838 * doc/autoconf.texi (Setting Output Variables): Document above
2839 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2840 use of multiline substitution.
2841 * tests/torture.at: No longer expect substitution of newline to fail.
2843 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2845 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
2846 From Ralf Menzel (trivial change).
2848 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2850 * tests/local.at: Don't attempt to check for negated character
2851 classes in shell scripts. The test was too brittle.
2853 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2855 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2856 * doc/autoconf.texi (Limitations of Builtins): Document this
2859 2005-05-24 Stepan Kasal <kasal@ucw.cz>
2861 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
2862 common code; used in many places in the tree.
2863 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
2864 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
2866 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
2868 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
2869 messages when ac_unique_file is not found.
2870 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2871 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2872 commands, for consistency with AC_MSG_ERROR and such.
2874 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2876 * bin/Makefile.am: Merge the two rules for creating scripts.
2878 2005-05-23 Stepan Kasal <kasal@ucw.cz>
2880 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
2881 obsolete; it was never documented.
2882 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
2884 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2886 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2887 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2888 (ac_top_builddir): ... this ...
2889 (ac_top_build_prefix): ... to this; the old name is also kept, for
2890 backward compatibility.
2891 (ac_top_builddir_sub): New variable, without the trailing slash,
2893 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2894 * doc/autoconf.texi (Configuration Actions): Rename
2895 ac_top_builddir to ac_top_build_prefix.
2896 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2897 at_top_builddir to at_top_build_prefix.
2898 * lib/autotest/general.m4 (AT_INIT): Likewise.
2900 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2902 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
2905 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2907 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2908 argument to m4_foreach. I guess it was necessary in the past,
2909 but I think it's a no-op now.
2911 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2913 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2914 ``cat <<_ACEOF'' commands to one.
2915 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2916 * lib/autoconf/status.m4: On various places, use expr instead of
2918 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2919 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2920 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2922 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2923 the wrong patterns between ``case'' and ``esac.'' The previous
2924 code had false positives.
2926 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2928 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

2971 2005-05-13 Stepan Kasal <kasal@ucw.cz>
2973 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
2975 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
2976 enough arguments, similarly as in m4_bpatsubsts.
2978 2005-05-12 Stepan Kasal <kasal@ucw.cz>
2980 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
2983 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2985 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2986 for absolute directory names in one loop.
2987 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
2988 abbreviations of --version and --debug.
2990 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2992 * doc/autoconf.texi (Autoconf Language): Be more precise about
2993 quoting rules. Problems noted by Stepan Kasal.
2994 Also, throughout this document, be more careful about white space.
2995 "blank", "white space", and "space" all have different meanings
2996 and we should be careful to say what we mean.
2998 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3000 Fix C++ related problems reported by Werner Lemberg.
3001 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3002 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3003 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3004 avoid problems with C++ and throw.
3005 * tests/compile.at: .cpp, not .cc.
3007 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3009 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3011 * doc/autoconf.texi (Generic Functions): Typos.
3013 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3015 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3016 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3017 set by latest automake.
3019 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3021 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3022 outputs 0 on GNU/Linux these days.
3024 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3026 * doc/autoconf.texi (Autoconf Language): Add more description
3027 about quoting heuristics.
3028 (Limitations of Builtins): Describe "set -" problems.
3030 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3032 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3035 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3036 by AC_DEFINE; it was a mistake.
3037 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3039 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3041 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3043 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3045 * doc/autoconf.texi (External Software): Quadrigraphs are not
3046 processed correctly in AS_HELP_STRING; avoid this in the examples.
3047 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3048 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3049 comment and reduce m4_default([foo], []) to [foo].
3050 (m4_strip): Update the explanation.
3052 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3054 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3055 Remove core.conftest.* too; it's generated by Tru64 5.1.
3056 Problem reported by Jennis Pruett.
3057 * lib/autoconf/functions.m4
3058 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3059 Don't bother to remove core files; AC_RUN_IFELSE should do that
3062 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3064 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

3068 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3069 Report from Horst Wente.
3071 2005-04-15 Stepan Kasal <kasal@ucw.cz>

3076 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3078 * doc/autoconf.texi (External Software, Package Options): Add
3079 examples showing how to implement --with-* and --enable-* options.
3081 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3083 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3084 as well as configure.in. Problem reported by Gregorio Guidi.
3086 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3088 * doc/autoconf.texi (Particular Functions): Use gnulib's current

3101 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3102 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3104 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3106 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3107 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3108 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3109 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3110 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3112 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3114 * NEWS: The configure command now warns you if you attempt to use
3115 a directory whose name contains a special character like space,
3117 * doc/autoconf.texi (Installation Directory Variables): Allow
3118 "," in file names. Do not use \@; it's not a portable regexp.
3119 * bin/Makefile.am (edit): Likewise.
3120 * lib/Makefile.am (edit): Likewise.
3121 * tests/Makefile.am (edit): Likewise.
3122 * tests/semantics.at: Likewise.
3123 * tests/torture.at: Likewise.
3124 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3125 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3126 * doc/autoconf.texi (File System Conventions): Warn about
3127 unportable file names.
3128 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3130 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3131 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3132 ac_pwd, and quote srcdir.
3133 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3135 * doc/autoconf.texi: Fix some systematic formatting problems.
3136 ".)" needs a following @: if not at the end of a sentence, and
3137 similarly for "!)". "etc." should be preceded by a comma.
3138 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3140 2005-03-22 Bruno Haible <bruno@clisp.org>
3142 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3143 argument is often called 'build-aux'.
3145 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3147 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3148 macro AC_TRY_LINK is obsolete.
3149 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3152 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3154 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3155 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3156 from a Common Lisp's `cl'.
3157 (AC_PROG_CXX): Behave according to the documentation: don't
3158 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3159 make the variable CCC precious; use `cl.exe', not `cl'.
3161 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3162 Alexandre Duret-Lutz <adl@gnu.org>
3164 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3165 /dev/null, as "configure" shouldn't read stdin, and this insulates
3166 us from problems (e.g., when testing for "cl"). Also, do this
3167 redirection before invoking "hostname" or "uname", and keep the
3168 original input stream available via...
3169 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3170 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3171 bother with "</dev/null" since it's now done at the top of
3173 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3174 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3175 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3176 * doc/autoconf.texi (File Descriptor Macros): New section.
3177 (Printing Messages): Mention it.
3178 * tests/base.at (Input/Output): New test.
3180 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3182 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3183 newline if neither \c nor -n work, as that would output two
3184 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3186 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3188 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3189 This causes that any required macros inside will get before the if.
3190 * doc/autoconf.texi (autom4te.cache): A typo.
3192 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3194 Undo previous change, except keep the change to
3195 lib/autoconf/programs.m4 that replaced grep with shell
3196 pattern-matching. This is because net-snmp configure reads stdin.
3197 Reported by Noah Misch.
3199 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3201 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3202 from /dev/null, as "configure" shouldn't read stdin, and this
3203 insulates us from problems (e.g., when testing for "cl").
3204 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3205 before invoking "hostname" or "uname".
3206 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3207 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3208 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3209 "</dev/null" since it's now done at the top of 'configure'.
3210 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3211 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3212 Also, replace grep with shell pattern-matching, to save a process.
3214 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3216 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3217 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3218 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3221 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3223 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3224 grep -q isn't portable. Improve grep -s explanation.
3225 Problem reported by Dan Manthey.
3227 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3229 * doc/autoconf.texi (Special Shell Variables): Clarify
3230 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3232 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3234 * doc/autoconf.texi: Use @acronym for DJGPP.
3235 Fix some @code's that should have been @env's, and vice versa.
3236 Sort environment variable names.
3237 Mention that shells no longer inherit IFS.
3238 Don't recommend PATH_SEPARATOR=';' so strongly.
3239 Mention that $RANDOM might expand to the empty string.
3240 "symlink" and "soft link" -> "symbolic link".
3241 Improve mktemp description (reported by Bruno Haible).
3243 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3245 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3246 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3248 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3251 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3253 * NEWS: Mention AT_COPYRIGHT.
3255 * tests/local.at (AT_CMP): Use diff directly on input files rather
3258 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3259 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3261 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3262 and Paul Eggert <eggert@cs.ucla.edu>
3264 * tests/autotest.at (Empty test suite): New test.
3265 * tests/torture.at (Substitute and define special characters)
3266 (Substitute a 2000-byte string, Define to a 2000-byte string)
3267 (Substitute a newline, Define a newline): New tests.
3269 2005-02-04 Noah Misch <noah@cs.caltech.edu>

3380 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3381 Update the long comment explaining it.
3383 m4_require no longer writes an ``is required by'' line to the
3384 execution stack. It contains only one bit of non-redundant
3385 information: that the macro was required, not called. And even
3386 this bit is useless in most situations: have you ever met a macro
3387 which both calls and requires the same macro?
3389 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3390 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3395 execution stack; slightly improve the out-of-a-defun error message.
3396 (_m4_divert_grow): New macro, counter for the temporary diversions.
3397 (_m4_require_call): Use it.
3398 * tests/m4sugar.at (m4_require): Expect output without the
3399 ``is required by'' messages.

3437 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3438 Warn about newline stripping in `` and $(). Update Solaris
3440 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3441 X insulates us from future changes to Posix.
3442 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

3467 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3469 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3495 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3496 stored in _m4_divert_diversion or _m4_divert_dump.
3497 (m4_divert_pop): When the parameter is given, compare the symbolic
3498 name with the last diversion pushed on the stack. Previously, the
3499 current diversion was compared with the numeric value of the
3500 diversion given as the parameter.
3501 (m4_require): If the macro hasn't been expanded yet, call ...
3502 (_m4_require_call): this new macro.
3504 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3781 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
3783 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
3784 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
3785 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
3786 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

3802 out the common code to ...
3803 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
3804 value of the #define--default to 1, iff the macro was called
3805 with exactly one parameter.
3807 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
3809 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3810 "char c = '\200';" rather than "char c = 0x80;" as the
3811 latter doesn't conform to the strict C standard due to
3812 overflow on signed char hosts.
3814 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3815 to -qlanglvl=ansi. We don't want to disable extensions.

3912 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
3914 * doc/autoconf.texi (auindex): New macro.
3915 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.

3927 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3929 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3930 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3931 (trivial change). Problem and patch reported by Andrew Church in:
3932 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

3961 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3962 texinfo.tex for now (done by hand now).
3963 * Makefile.maint (wget_files, cvs_files):
3964 Remove ansi2knr.c; nobody uses it.
3965 (ansi2knr.c-url_prefix): Remove.
3966 (cvs-update): Fix test for failure. I don't know why it ever
3969 * doc/autoconf.texi: Update URLs, some of which went stale.
3970 Use @uref rather than @href.
3972 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3973 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3975 * config/config.guess, config/config.sub, config/elisp-comp,
3976 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3977 doc/fdl.texi, doc/standards.texi: Sync with master copy.

3985 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
3986 tests/tools.at, tests/torture.at:
3987 Use "file name" rather than "filename" or "path",
3988 to be consistent with the terminology of the GNU coding standards.
3990 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3992 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3993 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with

3995 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3997 More fixes to support spaces in the name of the build directory.
3998 This isn't a complete fix but it's an improvement.
4000 * bin/autoconf.as (autom4te_options): New var.
4001 Use it instead of appending to AUTOM4TE, so that we can allow
4002 spaces in the build directory's absolute name.
4003 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4004 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4005 AT_CHECK_NOESCAPE): Likewise.

4018 and isnan. From a suggestion by Kevin Ryde.
4020 * lib/Autom4te/General.pm (END): Return correct exit status even
4021 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4023 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4025 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4026 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4027 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4029 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>

4034 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4035 * lib/autom4te.in (Automake-preselections): Preselect
4036 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4038 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4040 * lib/autom4te.in (Automake-preselections): Preselect
4041 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4044 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4046 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4048 * doc/autoconf.texi (Shellology): Mention BIN_SH.

4051 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4053 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4054 with pdksh, too. Problem reported by Patrick Welche via
4056 * doc/autoconf.texi (Shellology): Note that set -o posix is
4057 useful for pkdsh, too.
4059 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4061 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4062 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4063 Don't fail if ENV or BASH_ENV is readonly.
4064 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4065 etc. are read only. Problem reported by Ludovic Courtes.
4067 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4069 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4070 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4073 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4075 * doc/autoconf.texi (File System Conventions): Warn about
4076 names like "aux". Problem reported by Eric Blake.
4078 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4079 by zero instead of array size, so that we can use any arithmetic
4080 constant expression (instead of requiring an integer constant
4081 expression). This allows us to test expressions like DBL_MAX <
4082 LDBL_MAX, which didn't conform to the C standard using the old
4084 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4085 now that we can do floating-point tests at compile time.
4087 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4089 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4090 and LDBL_EPSILON, as the resulting expression isn't an
4091 integer constant expression and violates the C standard.
4092 Problem reported by Nelson H. F. Beebe. Also, check
4093 for "L" suffix, and check that long double doesn't have
4094 worse range or precision than double, that mixed-mode
4095 arithmetic doesn't generate a diagnostic, that double
4096 constants fit in long double.
4098 2004-06-03 Kevin Ryde <user42@zip.com.au>
4100 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4101 malloc(0) and realloc(NULL,size).
4103 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4106 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4108 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4109 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4112 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4114 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4115 can be rewritten using if-then-else. Suggested by Bruno Haible.
4117 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4119 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4120 Problem reported by Stepan Kasal.
4122 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4124 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4125 change). Patch reported by Ralf Wildenhues in
4126 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4128 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4129 function F exists if the compiler and linker let you compile an
4130 expression like (F != 0). Recent versions of GCC optimize away
4131 the reference to F in that case, since every function address must
4132 be nonzero, so the link succeeds even if F does not exist.
4133 Problem reported by Manu in
4134 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4136 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4137 "Unix". Many uses changed.
4138 (Limitations of Builtins): Explain better why the ! command isn't
4141 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4143 * lib/autom4te.in (Automake-preselections): Preselect
4144 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4146 2004-05-19 Kevin Ryde <user42@zip.com.au>
4148 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4149 referencing AC_FUNC_STRERROR_R.
4151 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4152 note pessimistic assumption when cross compiling.
4154 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4156 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4157 (until 2004) invoked subcommands with sh -e, contra POSIX.
4158 Reported by Kevin Ryde.
4160 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4162 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4163 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4164 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4165 `test -f " /usr/bin/grep"', which _always_ failed.
4166 (AC_PROG_SED): Ditto bogus PATH fix.
4167 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4168 requires that grep correctly supports _multiple_ `-e' options, rather
4169 than stating only that grep should accept `-e'.
4171 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4173 Port to C99, which requires that 'exit' be declared.
4175 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4176 to ensure that stdlib.h is included.
4177 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4178 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4179 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4180 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4181 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4182 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4183 when using 'exit' in a test; C99 requires that 'exit' be declared.
4185 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4187 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4188 now prefers 'grep' implementations that accept -e.
4189 (Limitations of Usual Tools): Describe problems of traditional
4190 egrep and fgrep with long input lines, and of traditional grep
4192 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4193 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4194 All callers changed. Append /usr/xpg4/bin to the PATH, for
4196 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4197 the user with complaints about multiple -e options.
4198 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4199 Define it with AC_PROG_GREP.
4200 * configure.ac (AC_PROG_GREP): Add.
4201 * lib/freeze.mk (GREP): New macro.
4203 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4205 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4206 a possible candidate only after all others fail, rather than
4207 consulting it first. This improves backward compatibility by
4208 better reflecting the way shell selection occurred in previous
4209 versions of Autoconf, and should help to avoid triggering latent
4210 problems in other packages, such as the one in Automake where zsh
4211 is not handled robustly:
4212 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4213 Although it is not Autoconf's responsibility to work around
4214 problems in Automake, it nevertheless makes sense to avoid
4215 introducing unnecessary incompatibilites.

4218 Gary V. Vaughan <gary@gnu.org>
4220 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess

4224 nested we are in this macro. Break out of all 3 nested loops if
4225 ac_path_TOOL_found is set.

4229 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4230 of the _AS_PATH_WALK loop too if GNU flavor is found.
4232 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4234 * doc/autoconf.texi (Limitations of Make): Update documentation
4235 for `$<'. New entry `Long lines', based on a report from Simon
4236 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4237 paragraph about DJGPP, based on a mail from Richard Dawe.
4239 2004-04-20 Paul Eggert <eggert@twinsun.com>
4241 * tests/c.at (C keywords): Don't assume that GCC supports
4242 "restrict" and "inline", as sufficiently-old GCC versions do not
4243 (also, GCC configured to be in pedantic C89 mode does not).
4244 Problem reported by Sumit Pandya in:
4245 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4247 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4248 consider -g to work if it generates warnings when plain compiles
4249 don't. Problem reported by Braden McDaniel in:
4250 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

4263 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4264 best tool so far counter rely on the tool path variable name to
4265 avoid checks for one tool being affected by the results of running
4266 the length check on a previous tool.
4268 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4269 match expression argument, as different greps have different
4270 regular expression flavours.
4271 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4273 (AC_PROG_EGREP): Pass 'EGREP$'.

4284 Types, Specific Compiler Characteristics, System Services,
4285 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4286 etc. consistently instead of 'long', 'short', 'unsigned' etc.

4299 2004-03-28 Paul Eggert <eggert@twinsun.com>
4301 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4302 now defines HAVE_DECL_TZNAME if it is declared, when
4303 HAVE_STRUCT_TM_TM_ZONE is not defined.
4304 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4305 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

4355 * NEWS: Document these changes.
4357 * doc/autoconf.texi: Avoid macros with unbraced arguments,

4374 * bin/Makefile.am (edit): Don't use $< in a context where
4375 POSIX doesn't require support for it. Use $@.in instead.
4376 Problem reported by Anthony N. Frasso in
4377 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4378 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

4382 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4383 from the next generation of Libtool.
4384 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4386 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4388 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4389 is not always thread-safe. Report from Nathanael Nerode.
4391 2004-02-18 Paul Eggert <eggert@twinsun.com>
4393 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4394 problem on QNX reported by Stephen Rasku in
4395 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4397 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4398 $(m4sh_m4f_dependencies); this removes a FIXME.
4399 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4400 (MAINTAINERCLEANFILES): Split into pieces,
4401 one per related section. Add $(srcdir)/wrapper.in.
4403 2004-02-09 Paul Eggert <eggert@twinsun.com>
4405 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4406 AC_SUBST provides no portable way to escape literal newlines.
4408 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4409 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4410 Darwin uses -lcrt2.o and there's little point to cataloging all
4411 the system variants. Partial fix reported by Andreas Waechter in:

4428 the behavior of the third argument.
4429 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4430 correctly the behavior of the third argument. Document

4439 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

4456 use AS_INIT_WITH_SHELL_FN.
4457 * bin/autoconf.in, tests/wrapper.in: Regenerated.

4485 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
4487 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4488 2003 (except 1997) to the list of copyright years. This undoes
4489 the 2003-05-22 change, which removed the older years from the list.
4490 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

4498 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4500 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4501 egrep and fgrep respectively if $GREP -E/-F don't work.
4502 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4503 _AC_PROG_GREP, and AC_PROG_SED.
4504 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4505 longest input length accepted by a command.

4534 2004-01-26 Paul Eggert <eggert@twinsun.com>
4536 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4537 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4538 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4539 not <inttypes.h>. Problem reported by Tim Mooney in
4540 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4541 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4544 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4545 otherwise "make check" fails because it forbids cmp (I guess
4546 because cmp treats files as binary on DOS-like systems).
4548 * tests/mktests.sh: Update copyright date to 2004, since some tests
4549 have changed in 2004.
4551 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4553 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4554 non-truncating sed or gsed program in PATH.
4555 * tests/acprograms.at: Add it.
4556 * doc/autoconf.texi (Particular Programs): Document it.
4559 2004-01-15 Paul Eggert <eggert@twinsun.com>
4561 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4562 -std1 disables some useful extensions on Tru64. Problem reported
4564 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4566 2004-01-14 Paul Eggert <eggert@twinsun.com>
4568 * doc/autoconf.texi (Programming in M4sh): Document that
4569 AS_MKDIR_P succeeds if the destination is a symbolic link
4570 to an existing directory.
4571 (Limitations of Usual Tools): Note that mkdir -p might not
4572 succeed on symlinks to directories.
4574 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4576 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

4586 2004-01-10 Jim Meyering <jim@meyering.net>
4588 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4590 2004-01-09 Paul Eggert <eggert@twinsun.com>
4592 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4593 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4594 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4595 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4596 AC_COMPILE_IFELSE, since we now assume our caller invokes
4597 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4598 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4599 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4600 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4602 2004-01-07 Paul Eggert <eggert@twinsun.com>
4604 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4605 `"'...'"`, as it's confusing (and I suspect it may not work on
4606 some platforms). The code was incorrect anyway, as it assumed
4607 that \$ evaluated to itself in that context. Reported by
4608 Alexandre Duret-Lutz.
4610 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4612 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

4618 example, and add more examples. Reported by Eric Sunshine.
4620 2004-01-05 Paul Eggert <eggert@twinsun.com>
4622 * doc/autoconf.texi (Limitations of Usual Tools):
4623 Remove warning against "rm -fr" introduced yesterday; it
4626 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4627 autoscan, autoupdate, ifnames): Don't use chmod -w.

4638 2004-01-04 Paul Eggert <eggert@twinsun.com>
4640 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):

4968 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

4993 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4994 cache variable instead of $G77 to decide whether to include -O2,
4995 since $G77 is specific to Fortran 77.

4999 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

5002 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5004 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the

5108 The test suite are sometimes assigning timings incorrectly.
5109 Reported by Henk Krus.
5110 Diagnosed by Nicolas Joly.
5112 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as

5130 (ifnames): chmod -w.
5131 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5132 executables, not bin/ executables! Otherwise all the magic needed
5133 to find non installed files is turned off. This caused a failure
5134 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5135 as found in its environment (sent by tests/autoreconf): pointing
5136 to bin/autom4te that could not find its files.

5138 the sake of "mv" program that are interactive when overwriting a

5235 Add support for newer Fortran dialects. The F77 interface is
5236 unchanged, and continues to support Fortran 77. New FC macros
5237 correspond to all the old F77 macros, with output variables FC,
5238 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5239 available dialect, but older dialects can be specified. There are

5367 2003-08-21 Akim Demaille <akim@epita.fr>
5369 First stab at preserving warnings between calls to autom4te,
5370 including when the cache is used.
5372 There are still several issues: (i) there are too many runs of m4
5373 (one for include, one for warnings, and some more), (ii) warnings
5374 spreading on several lines are not handled gracefully, (iii) the
5375 code meant to have the call stack display for errors does not work
5376 (its handling should move from m4 to autom4te).
5378 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5380 (@preselect): Add m4_warn.
5381 ($exit_status): Remove, use $exit_code.
5382 ($help): Use Autom4te::ChannelDefs::usage.
5383 (&handle_m4): No longer define the m4_warnings.
5384 At each run, extract and report the warnings.
5385 Always cache the result, including if the exit status is on
5386 failure, since if nothing changes, we should result in the same
5387 failure, hence we can use the cache.
5388 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5389 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5391 (m4_warn): Redefine as a do-nothing: it is its invocation that
5392 matters, as warnings are now reported via traces.
5393 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5394 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5395 the latter reveals calls to the former.
5399 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5401 2003-08-21 Akim Demaille <akim@epita.fr>
5403 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

5411 (&parse_warnings): Accept a list of warning requests.
5412 (&usage): Return a string, not a side effect.
5413 (cross): New warning category.

5418 (&require_configure_ac): Accept an optional directory argument.
5419 ($configure_ac): Remove.

5422 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5423 * bin/autoscan.in: Adjust.
5425 2003-08-20 Akim Demaille <akim@epita.fr>
5427 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5428 Reported by Alexandre Duret-Lutz.
5430 2003-08-20 Akim Demaille <akim@epita.fr>
5432 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5433 * bin/autom4te: Adjust.
5434 In particular, be Autoconf tools are really silent when properly
5435 working, bind the verbosity of the 'note' channel to $verbose.
5436 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5437 (&xsystem, &contents): Remove, since they are exported by...
5438 * lib/Autom4te/FileUtils.pm: this.

5664 the middle of a line).
5665 * lib/m4sugar/m4sugar.m4: Likewise.
5666 Remove useless spaces in comments.
5668 2003-05-23 Akim Demaille <akim@epita.fr>
5670 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5671 exit 63, so that we (or Automake's "missing") can tell the
5672 difference with a plain failure.
5673 * doc/autoconf.texi (Notices): Adjust.
5675 2003-05-23 Akim Demaille <akim@epita.fr>
5677 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5678 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5679 White spaces cleanup.
5681 2003-05-22 Jim Meyering <jim@meyering.net>
5682 Paul Eggert <eggert@twinsun.com>
5684 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5685 Remove `#include <stdlib.h>' from the list; we should never
5686 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5687 resulting namespace pollution would cause other tests to fail.
5688 Configure scripts run with some older versions of g++ and HP's
5689 aCC would fail due to such an #include. Problems reported by
5690 Matthew Mueller in <http://bugs.debian.org/120704> and by
5692 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5693 In the test, use the test declaration before including <stdlib.h>,
5694 as that's closer to how it'll be used.
5696 2003-05-23 Akim Demaille <akim@epita.fr>
5698 * doc/autoconf.texi (Header Portability): ucred.h.
5701 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5703 Overhaul Autotest's logging: generate separate log files
5704 in testsuite.dir/NNN/testsuite.log, and append them to
5705 testsuite.log instead of re-running the test verbosely.
5707 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5708 file descriptor, write 0 to at_status_file instead of setting
5709 at_status=0, initialize some new variables (at_status_file,
5710 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5711 to rerun the tests, instead append the at_group_log to the
5712 at_suite_log when a test fails.
5713 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5714 with the AS_MESSAGE_LOG_FD redirected to stdout.
5715 (AT_CLEANUP): save the output status in $at_status_file
5716 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5718 (AT_CHECK): since tests are run with a redirected stdout,
5719 and used to be re-run in verbose mode, turn some $at_verbose
5720 into echo, and don't redirect the output of testing stdout
5723 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5724 the name of the debugging directory and information about
5727 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

5839 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
5841 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
5844 2003-05-06 Akim Demaille <akim@epita.fr>
5846 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5847 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5848 by aclocal.m4 is changed it might require the importing of another
5849 m4 extension file, i.e., aclocal must be run.
5851 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5852 (&parse_args): Use --force with aclocal if required and supported.
5853 (&autoreconf_current_directory): Use &run_aclocal.
5855 2003-05-06 Akim Demaille <akim@epita.fr>
5857 Lock autom4te's cache.
5859 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
5860 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5861 argument instead of a file name, so that the request file remains
5862 open during the whole autom4te run.
5863 ($icache_file): New.
5864 (&freeze): Lock the $icache_file.
5866 2003-04-29 Derek Price <derek@ximbiot.com>
5868 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5869 seperator with m4_append_uniq(). It doesn't work.
5870 (AT_CLEANUP): Add `;' to end of at_help_all.
5871 (AT_INIT): Allow --keywords to be specified more than once. When
5872 grepping $at_help_all for keywords, use the field and keyword
5873 seperators to ensure a complete keyword match. Alter at_prev handling
5874 to support the new --keywords behavior.
5876 2003-04-27 Karl Berry <karl@freefriends.org>
5878 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5879 align better with others. I also made some of the individual
5880 entries on one line, for brevity and to make it easier for me to
5881 sort my dir-example file in the Texinfo distribution :).
5883 2003-04-12 Jim Meyering <jim@meyering.net>
5885 * NEWS: Mention the new macro.

5942 Suggested by Paul Eggert.
5944 2003-03-28 Akim Demaille <akim@epita.fr>
5946 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
5947 reading the section "Present But Cannot Be Compiled" when the
5948 header causes problems.
5950 2003-03-28 Akim Demaille <akim@epita.fr>
5952 * tests/torture.at (Configuring subdirectories): Require aclocal
5953 1.4, otherwise the test fails, as it does support configure.ac.
5954 This fixes the "test 40 failed" bug reports.
5956 2003-03-28 Akim Demaille <akim@epita.fr>
5958 * doc/autoconf.texi (C Compiler): `#line' portability.

5968 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
5969 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
5970 use new diversions in preparation for accepting new arguments and
5971 allowing scripting around tests.
5972 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
5974 2003-03-26 Derek Price <derek@ximbiot.com>
5976 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of

6023 * doc/autoconf.texi (Limitations of Make): Remove the section
6024 about `$<' in inference rules, it was a bogus interpretation of
6025 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6026 Tru64 make in the "target lookup" section.
6027 (Automake): Automake 1.5+ no longer requires special tools to be
6028 present on the developer's host.
6030 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6032 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
6033 to a shell that can handle redirection or quoting correctly.
6034 Override SHELL with the shell detected by configure.

6045 to cope with DOS-style absolute paths, when constructing
6048 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6049 When constructing paths with IFS=:, quote the path. If we're
6050 constructing a DOS-style absolute path, we don't want to split it
6053 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6056 2003-02-25 Pavel Roskin <proski@gnu.org>
6058 * bin/autoheader.in: Add missing newline when printing

6073 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6074 format starting with "-".
6076 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6078 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6079 is not portable inside Makefile.
6081 2003-02-20 Akim Demaille <akim@epita.fr>
6083 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6084 compiler says yeah, but preproc says nope, compiler is right.
6085 Conversely, prompt the reader to send a bug report to the
6086 maintainers of the package, not of Autoconf.
6088 2003-02-20 Klee Dienes <kdienes@apple.com>
6090 * bin/autoreconf.in (autoreconf_current_directory): Properly
6091 handle an empty aclocal.m4.

6101 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6102 innocuous variant befor including <limits.h> or <assert.h>. This
6103 works around a bug reported by Albert Chin: HP-UX 11i
6104 (and earlier versions) have a <limits.h> that declares
6105 gettimeofday and many other functions.
6107 2002-12-03 Paul Eggert <eggert@twinsun.com>
6111 * NEWS, configure.ac: Update version.
6113 * doc/fdl.texi: Upgrade to FDL version 1.2.
6115 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6116 nontrivially in main's body, so that f's external declaration is
6117 not optimized away in AIX. This should fix the bug reported by
6119 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6121 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6122 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6123 defined, to support freestanding compilers. This should fix the
6124 bug reported by Momchil Velkov in
6125 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6127 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6128 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6129 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6130 by Simon Josefsson in
6131 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
6133 * Makefile.maint (www-gnu): New macro.

6135 the location has moved.
6137 2002-12-02 Martin Frydl <martin@systinet.com>
6139 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6140 \(.*\) match is too long and there is something more to be checked.
6141 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

6154 2002-11-14 Akim Demaille <akim@epita.fr>
6158 * config/config.guess, config/config.sub, config/install-sh:
6159 Update from masters.
6161 2002-11-14 Akim Demaille <akim@epita.fr>
6163 * Makefile.maint: Sync with Bison, i.e.:
6164 (po-check): Scan .l and .y files instead of the
6165 .c and the .h files that they generate. This fixes the bug
6166 reported by Tim Van Holder in:
6167 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>

6189 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6190 option. Process --recheck after parsing all options. Pass -q

6225 2002-11-05 Akim Demaille <akim@epita.fr>
6227 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6229 We _have_ to stop using the old compatibility scheme that tried to
6230 avoid useless backslashes because Libtool 1.4.3 contains a
6231 AC_DEFINE([error_t], [int],
6232 [Define to a type to use for \`error_t' if it is not
6233 otherwise available.])
6234 We _have_ to quote the single quote and backslashes with \. The
6235 old compatibility scheme saw that ` was backslashed, and therefore
6236 did not quote the single quote. Hence before this patch, Autoconf
6237 was not compatible with Libtool.

6694 Instead of blindly running autopoint, scan configure.ac (not the
6695 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6696 Reported by Paul D. Smith.

6700 Work around problems found when POSIXLY_CORRECT=1 is set.
6701 None of this seems to have anything to do with POSIX, really,
6702 but it's how Perl getopt works.
6703 * bin/autom4te.in (parse_args): Configure GetOpt with
6705 * doc/autoconf.texi (Invoking autom4te):
6706 --warning -> --warnings.
6707 * lib/autom4te.in: --warning -> --warnings.
6709 2002-09-28 Akim Demaille <akim@epita.fr>
6711 * doc/autoconf.texi (autom4te.cache): New section.
6713 2002-09-28 Akim Demaille <akim@epita.fr>
6715 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
6716 (Automake-preselections): Update.
6717 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
6719 2002-09-28 Akim Demaille <akim@epita.fr>
6721 * lib/autoscan/autoscan.pre: Move all the remaining rules to...

6723 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
6724 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
6726 2002-09-28 Akim Demaille <akim@epita.fr>
6728 * tests/torture.at (Configuring subdirectories): Be robust to
6729 users who use config.site to require for a cache: in this case,
6730 the two last configure runs, using two different sets of
6731 arguments, trigger a legitimate error.
6733 2002-09-28 Akim Demaille <akim@epita.fr>
6735 * tests/m4sh.at (Functions Support, Functions and return Support):
6738 2002-09-28 Akim Demaille <akim@epita.fr>

6763 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
6764 that were listed in the original autoscan.list.
6765 * lib/autoconf/headers.m4: Similarly with headers.
6766 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6767 (.m4.m4f): Don't pass --prepend-include, since that's done by
6768 tests/autom4te itself.
6769 * lib/autoscan/Makefile.am: Include freeze.mk.
6770 (autoscan.list): New target --this file is no longer a source.
6771 (autoscan.pre): New file.
6773 2002-09-28 Akim Demaille <akim@epita.fr>
6775 * bin/autoscan.in (@kinds): Make them singular.
6777 (&init_tables): When --debug, report the list of rules to ease
6778 tracking changes in autoscan.list.
6779 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6781 2002-09-28 Akim Demaille <akim@epita.fr>
6783 * lib/autoscan/functions, lib/autoscan/headers,
6784 * lib/autoscan/identifiers, lib/autoscan/makevars,
6785 * lib/autoscan/programs: Merge into...
6786 * lib/autoscan/autoscan.list: this.
6787 * bin/autoscan.in (&init_tables): Adjust.
6789 2002-09-28 Akim Demaille <akim@epita.fr>
6791 * lib/autoscan/functions, lib/autoscan/headers,
6792 * lib/autoscan/identifiers, lib/autoscan/makevars,
6793 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6794 `functions' line is now prefixed with `function:'.
6795 * bin/autoscan.in (&init_tables): Adjust.
6797 2002-09-28 Akim Demaille <akim@epita.fr>
6799 From now on, autoscan files must always map a macro name to a
6800 word: there is no `default' macro for autoscan.
6802 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6804 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6807 2002-09-28 Akim Demaille <akim@epita.fr>
6809 * bin/autoscan.in (%c_keywords): Remove.
6810 (&used): Keep only track of the words we might be interested in.
6811 (&output_kind): It is no longer needed to look for non active
6814 2002-09-27 Akim Demaille <akim@epita.fr>

6817 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
6818 * lib/autoscan/functions: Adjust.
6819 * doc/autoconf.texi (Particular Functions): Adjust.
6821 2002-09-27 Akim Demaille <akim@epita.fr>
6823 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
6825 Thanks to Bill Moseley and Paul Eggert.
6826 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
6827 the tmpdir must be created.
6828 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
6829 dir be in the build tree, instead of $TMPDIR.
6831 2002-09-27 Akim Demaille <akim@epita.fr>
6833 * bin/autoscan.in: Improve the comments.
6834 (&parse_args): Drop obsolete undocumented options.
6835 (&output_kind): Output warnings.
6836 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
6837 (getwd): Trigger a warning.
6839 2002-09-26 Akim Demaille <akim@epita.fr>
6841 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
6842 Reported by Ralf Corsepius.
6843 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6845 2002-09-26 Akim Demaille <akim@epita.fr>
6847 Single suffix rules and seperated dependencies are not portable.
6849 * doc/autoconf.texi (Installation Directory Variables): Update.
6850 (Limitations of Make): Some about `Single Suffix Rules and
6851 Separated Dependencies'.
6852 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6853 (ifnames, autoscan, autom4te): Un-factor into several rules.
6855 2002-09-25 Paul Eggert <eggert@twinsun.com>
6857 * BUGS (Interoperability bugs): New section. Mention libtool
6858 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
6860 2002-09-24 Paul Eggert <eggert@twinsun.com>
6862 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
6863 make handles suffix-rules differently from GNU make.
6865 * bin/Makefile.am (SUFFIXES, .in): Remove.
6866 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
6867 Move the body of the old .in rule here.
6869 2002-09-16 Akim Demaille <akim@epita.fr>
6871 i960 compilers create `b.out' files by default.
6872 Reported by Ralf Corsepius.
6874 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
6875 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
6877 2002-09-13 Paul Eggert <eggert@twinsun.com>
6879 * doc/autoconf.texi (Particular Headers): Remove obsolete
6880 reference to `struct timezone' in the description of
6883 2002-09-13 Akim Demaille <akim@epita.fr>
6887 * config/config.sub, config/config.guess: Update.
6888 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6889 * Makefile.am: Adjust.
6891 2002-09-13 Akim Demaille <akim@epita.fr>
6893 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6894 reading config.log when the compiler is rejected.
6895 Suggested by Guido Draheim.
6897 2002-09-13 Akim Demaille <akim@epita.fr>
6899 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6900 (chdir_init) might hang when stat'ing mounted directories.
6901 Reported by Vance Shipley.
6903 2002-09-12 Akim Demaille <akim@epita.fr>
6905 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6908 2002-09-12 Akim Demaille <akim@epita.fr>
6910 * doc/autoconf.texi (Defining Symbols): Present two different
6911 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6912 difference between 1 argument calls, and 2-3 argument calls.
6914 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6916 * doc/autoconf.texi: Review grammar and punctuation.
6918 2002-09-11 Paul Eggert <eggert@twinsun.com>
6920 * doc/autoconf.texi: Fix minor formatting, spelling, and
6922 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6923 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6926 2002-09-11 Akim Demaille <akim@epita.fr>
6928 * doc/autoconf.texi (Questions): Rename as...
6930 (Defining Directories): New.
6932 2002-09-09 Akim Demaille <akim@epita.fr>
6934 * doc/autoconf.texi (Making testsuite Scripts): Update.
6935 Suggested by Nishio Futoshi.
6937 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6939 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6940 plain `@' is wanted.
6942 2002-09-09 Akim Demaille <akim@epita.fr>
6944 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6945 `duplicates', since the algorithm was too naive and could keep
6946 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6947 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6948 Reported by Ralf Corsepius.
6949 * tests/torture.at (Configuring subdirectories): Exercise these
6952 2002-09-09 Akim Demaille <akim@epita.fr>
6954 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6955 looking for a replacement file.
6956 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6957 directory is relative.
6958 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6959 directory definition.
6960 Reported by Andreas Schwab and Jim Meyering.
6962 2002-09-06 Akim Demaille <akim@epita.fr>
6964 * doc/autoconf.texi (Setting Output Variables): Clarify what
6965 precious variables are.
6966 Suggested by Pontus Skoeld.
6968 2002-09-05 Akim Demaille <akim@epita.fr>
6970 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6971 (ifnames, autoscan, autom4te): Since we don't only depend on
6972 configure.ac variables (such as VERSION etc.), but also on prefix
6973 and so forth, depend on Makefile, not configure.ac.
6974 Reported by Alexandre Duret-Lutz.
6975 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6977 2002-09-05 Kevin Ryde <user42@zip.com.au>
6979 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6980 doesn't seem to be confined to ia64, just say "some versions".
6982 2002-09-04 Akim Demaille <akim@epita.fr>
6984 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6986 * Makefile.am (maintainer-clean-local): Remove.
6987 (MAINTAINERCLEANFILES): Remove COPYING.
6989 2002-09-03 Paul Eggert <eggert@twinsun.com>
6991 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6992 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6995 2002-09-03 Akim Demaille <akim@epita.fr>
6997 * configure.ac: Bump to 2.53d.
6998 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6999 as of today, on Automake's team suggestion.
7001 2002-09-03 Akim Demaille <akim@epita.fr>
7005 2002-09-02 Akim Demaille <akim@epita.fr>
7007 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7009 * configure.ac: Disable SITE_MACRO_DIR.
7011 2002-09-02 Jim Meyering <meyering@lucent.com>
7013 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7014 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7015 Also, tweak grammar: s/make sure to/be sure to/.
7017 2002-09-02 Paul Eggert <eggert@twinsun.com>
7019 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7020 directory names are generally preferable to physical names.
7022 2002-09-02 Akim Demaille <akim@epita.fr>
7024 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7025 Reported by Raja R. Harinath.
7026 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7027 * bin/autoupdate.in: Use error instead of die.
7029 2002-09-01 Paul Eggert <eggert@twinsun.com>
7031 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7032 ordinary shell concatenation rather than echo+tr+sed command that
7033 runs afoul of a long-line-related sed bug in Solaris 8.
7035 * bin/autoheader.in (parse_args): --warning -> --warnings.
7037 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7038 stdout, as traditional "ls" does.
7039 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7040 _AC_COMPILER_EXEEXT_O): Likewise.
7041 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7043 * bin/autoconf.as: Add --prepend-include option. This patch was
7044 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7045 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7047 * bin/autoconf.in, configure: Regenerate.
7049 * doc/autoconf.texi (Special Shell Variables): Mention
7050 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7052 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7053 MAILPATH and set PS1, PS2, PS4 to default values, to work
7054 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7055 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7056 the Autoconf documentation specifies; fall back to "unset" only if
7057 this fails. Use a shell for-loop for this rather than an m4 loop,
7058 to shorten the output script.
7060 2002-08-30 Paul Eggert <eggert@twinsun.com>
7062 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7063 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7064 for the CDPATH problem. Document PWD.
7065 (Limitations of Builtins): Document the problem that "cd $foo" and
7066 "ls $foo" may refer to different directories in shells conforming
7067 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7068 example, since the old example is now out of date.
7070 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7071 FOO" and "ls FOO" talk about different directories; this catches
7072 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7075 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7076 of rolling our own unset.
7077 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7078 in practice we needn't worry about CDPATH if unset doesn't work.
7080 * Makefile.in, aclocal.m4, bin/Makefile.in,
7081 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7082 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7083 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7084 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7085 tests/Makefile.in: Regenerate with Automake 1.6.3.
7087 * config/config.guess, config/config.sub, config/mkinstalldirs:
7090 * configure: Regenerate with self.
7092 2002-08-30 Kevin Ryde <user42@zip.com.au>
7094 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7097 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7099 * bin/autom4te.in (Request::load): Correctly test for "do" read
7102 2002-08-29 Akim Demaille <akim@epita.fr>
7104 * lib/Autom4te/General.pm (&xqx): New.
7105 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7106 hand, which is not portable.
7108 * bin/autom4te.in: Use them.
7109 Use &error instead of die.
7110 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7113 2002-08-17 Paul Eggert <eggert@twinsun.com>
7115 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7116 default list of compilers to try, since it was long ago superseded
7117 by the ksh fc builtin. Suggested by Steven G. Johnson.
7119 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7121 * doc/autoconf.texi (Invoking autom4te): End the option table,
7122 fixing a bug introduced by the previous patch.
7123 (Limitations of Make): Add a 'target lookup' subentry in the
7124 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7126 2002-07-29 Mark D. Roth <roth@feep.net>
7128 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7129 options and use $AUTOM4TE_PATH.
7130 * doc/autoconf.texi: Remove documentation of autom4te
7131 --include-envvar and --site-macro-subdir options and document
7132 use of $AUTOM4TE_PATH.
7133 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7134 arguments from each language section.
7136 2002-07-29 Paul Eggert <eggert@twinsun.com>
7138 * doc/install.texi: Include copyright symbol in copyright notice.
7140 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7142 (AM_MAKEINFOFLAGS): New macro.
7143 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7144 * Makefile.am (INSTALL): Use the new macros.
7145 Use -o rather than --output, since "missing" does not grok --output.
7147 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7149 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7150 comments do not always work. Never trust the exit status of
7153 2002-07-24 Kevin Ryde <user42@zip.com.au>
7155 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7156 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7158 2002-07-23 Paul Eggert <eggert@twinsun.com>
7160 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7161 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7162 apparently treats PATH="nonexistent" as if it contained ".".
7163 Bug reported by Stefan `Sec' Zehl.
7165 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7167 * doc/autoconf.texi (Limitations of Make): Mention the special
7168 handling of the obj/ directory by BSD make.
7170 2002-07-20 Kevin Ryde <user42@zip.com.au>
7172 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7175 2002-07-19 Akim Demaille <akim@epita.fr>
7177 * doc/autoconf.texi (Function Portability): `exit'.
7178 (Programming in M4sh): Ethymology of M4sh.
7180 2002-07-19 Akim Demaille <akim@epita.fr>

7192 2002-07-18 Akim Demaille <akim@epita.fr>
7194 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7197 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.

7199 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7201 2002-07-18 Akim Demaille <akim@epita.fr>,
7202 Alexandre Duret-Lutz <duret_g@epita.fr>

7435 2002-05-16 Paul Eggert <eggert@twinsun.com>
7437 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7438 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7439 Both macros now accept an optional source-dir arg.
7440 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7442 * NEWS: Document this.
7443 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7445 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7446 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

7459 Bug reported by Stephen Gildea.
7461 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7462 If prototypes are supported, use them to check this at compile-time,
7463 instead of trying to check it at run-time. If we must do a run-time
7464 check, assume that setvbuf is standard when cross-compiling, as
7465 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7466 Bug reported by Paul D. Smith.
7468 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7469 argument specifying location of getloadavg.c. This removes a
7470 FIXME. This idea was taken from Jim Meyering's implementation in
7472 * doc/autoconf.texi (Particular Functions): Document this.
7473 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7474 that's what the code does; this fixes a bug reported by

7480 autopoint instead of gettextize.
7481 ($uses_alocal): Rename as...
7482 ($uses_aclocal): this.

7492 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7493 files to be 1 second older; just set them to be the same time.
7494 Also, sleep 1 second after the first aclocal, to work around
7495 problems with sub-second time stamps on the input files.
7497 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>

7510 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7511 of lack of $LINENO support, then the test will compare the $LINENO
7512 in testsuite vs. the lineno in the test file. This is wrong, of
7514 Be sure to protect it.
7515 Reported by Patrick Welche.

7519 * doc/autoconf.texi (Obsolete Macros): Typo.
7520 Reported by Vladimir Volovich.
7522 2002-04-25 Akim Demaille <akim@epita.fr>
7524 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7525 than some of the input files, hence, on the second run of aclocal,
7526 if some of its input are younger, make them older.
7527 Suggested by Paul Eggert.
7529 2002-04-25 Akim Demaille <akim@epita.fr>
7531 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

7537 and ac_subst_vars be sh variables containing the list of
7538 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the

7541 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7542 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7543 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in

7551 config.h.in that was to be created.
7553 2002-04-23 Akim Demaille <akim@epita.fr>

7704 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7705 contains no literal separators.
7707 2002-04-03 Akim Demaille <akim@epita.fr>
7709 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7710 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7711 Use dnl, not the KILL diversion.
7713 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7714 (AC_CONFIG_LINKS): here.
7716 Don't use the KILL diversion, as it kills spurious output, which
7717 results in failures being hidden.
7718 Use m4_defn where appropriate.
7719 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7720 after the second argument.
7722 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7723 syntax, as it is provided by M4sugar.
7724 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7726 2002-04-03 Andreas Schwab <schwab@suse.de>
7728 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7729 expanded if $# <= 2.

7745 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7747 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7748 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7749 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7750 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.

7763 2002-03-28 Kevin Ryde <user42@zip.com.au>
7765 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7766 to avoid versions of HP C which don't allow that.
7768 2002-03-27 Paul Eggert <eggert@twinsun.com>
7770 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7771 (AS_SHELL_SANITIZE): Invoke it.

7782 2002-03-25 Paul Eggert <eggert@twinsun.com>
7784 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7785 as POSIX requires, as it doesn't work with Zsh.
7786 * doc/autoconf.texi (Assignments): Document the problem.
7788 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7790 * doc/autoconf.texi (Limitations of Make): Mention more issue
7791 about VPATH, overriding of macros in sub-makes, and handling of

7796 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7797 problem with here-document buffer boundaries.
7799 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7800 when reinvoking the shell, to work around problems with installers
7801 who put strange things like "cd" commands in their environments.

7825 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7826 (Limitations of Usual Tools): Add mkdir section.
7828 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7829 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7830 back on AS_DIRNAME to compute prefixes otherwise; this is
7831 roughly what mkinstalldirs does. That way, we need not have
7832 our own filename disassembler. The old disassembler did not
7833 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7835 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7836 Create at_test_all by a series of assignments,
7837 not by a single assignment of a long string. The latter causes ksh
7838 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7839 presumably because of a buffer overrun.
7841 2002-03-14 Paul Eggert <eggert@twinsun.com>
7843 * lib/autotest/general.m4 (at_times_skip):
7844 Renamed from at_times. Now a boolean.
7845 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7846 says 'times: not found'.
7848 2002-03-14 Akim Demaille <akim@epita.fr>
7850 * bin/autoreconf.in (&study_gettextize): New.
7851 (&autoreconf): Handle newest gettextize.

7887 subdirectory should exist.
7889 2002-03-08 Akim Demaille <akim@epita.fr>
7891 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7893 2002-03-08 Akim Demaille <akim@epita.fr>
7895 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7896 aliases the actual variables, and modifications of the former
7899 2002-03-08 Akim Demaille <akim@epita.fr>
7901 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7902 because of C-c: have m4 output in tmp files, then mv them.
7904 2002-03-08 Akim Demaille <akim@epita.fr>

7934 2002-03-04 Akim Demaille <akim@epita.fr>
7936 * doc/autoconf.texi (Transforming Names): Equality between target
7937 and host is irrelevant.
7938 (Specifying Names, Canonicalizing): Remove all references to the
7939 backward compatibility hooks. Rather, collect them all into...
7940 (Hosts and Cross-Compilation): this new section.
7941 * doc/install.texi (System Type): Ditto.
7942 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7943 that `--host' implies cross-compilation.
7945 2002-03-04 Akim Demaille <akim@epita.fr>
7947 * doc/autoconf.texi (Evaluation Macros): New.
7948 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7950 (_m4_foreach): Define the variant with immediate evaluation so
7951 that it contains exactly the items, not an expression which
7952 evaluation is the current item.
7953 (m4_re_string, m4_re_word): Don't over quote them.
7955 2002-03-04 Akim Demaille <akim@epita.fr>
7957 Instead of having stacking `shift's evaluated at the end, let
7958 `foreach' loops immediately evaluate them.
7960 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7961 $*. This is the n-th time I change my mind, but hopefully this is
7964 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7966 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7967 it was only a hack for m4_text_wrap.
7968 (m4_car2): Remove, replaced by...
7970 (_m4_foreach): Adjust.
7971 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7972 m4_bpatsubst for clarification.

8024 AC_PREFIX_PROGRAM fails with dashed program names
8026 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

8060 cross-compilers, too. This undoes some of the most recent change
8063 2002-02-05 Akim Demaille <akim@epita.fr>
8065 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8089 Also, pass `--reload-state=' on them, so...
8091 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8092 (M4sh): Rely on M4sugar.
8093 (Autotest, M4sh, M4sugar): Use frozen files.

8130 2002-01-28 Akim Demaille <akim@epita.fr>
8132 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8133 AUTOTEST_PATH *after* it was set.
8134 Don't put `.' in the PATH: the user should be precise and `./' if
8135 needed. In addition, given that the test suite does some `cd', if
8136 `.' is in the path, the `tested programs' sections will report
8137 programs found in the test suite's directory, while during the
8138 tests (performed in their own directory), these programs are no
8139 longer visible. In other words, the results is confusing and
8141 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

8245 2001-12-14 Akim Demaille <akim@epita.fr>
8247 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8248 trailing files, don't apply `-rf' to files which might not be
8249 created by configure (core, core.*, and *.core), but just `rm -f'.
8250 Suggested by Jonathan Kamens.
8252 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8254 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8256 2001-12-14 Akim Demaille <akim@epita.fr>
8258 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8260 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8262 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8263 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8264 abs_srcdir, top_srcpath to abs_top_srcdir.
8265 (_AC_OUTPUT_FILES): Adjust.
8266 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8267 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8268 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8270 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8272 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8273 C/Fortran linking on HP/UX, by extracting the Fortran library
8274 search path from the LPATH line in the $F77 -v output.
8276 2001-12-12 Kevin Ryde <user42@zip.com.au>
8278 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8279 forbidden file descriptors table.
8281 2001-11-26 Akim Demaille <akim@epita.fr>
8283 * bin/autoscan.in (%c_keywords): Build it at top level.
8284 Map to 1 in order to simplify its uses.
8286 2001-11-26 Akim Demaille <akim@epita.fr>
8288 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8289 Remove $filepath, useless.
8290 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8291 variables, they are really part of the tokens.
8292 Split the input line on spaces and then look for tokens.
8293 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8294 because of `lex$U.$(OBJEXT)'.
8295 (&scan_files): Use "@list" instead of join.
8296 * doc/Makefile.am (CLEANFILES): Add *.fns.
8298 2001-11-26 Akim Demaille <akim@epita.fr>
8300 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8301 Remove, replaced by...
8302 * tests/wrappl.in: Be common for all the Perl executables.
8303 In particular autoscan and autoheader want -I.
8304 * configure.ac: Adjust.
8305 * lib/autoscan/headers: errno.h is portable.
8307 2001-11-26 Akim Demaille <akim@epita.fr>
8309 * bin/autoscan.in (used): New.
8312 2001-11-26 Akim Demaille <akim@epita.fr>
8314 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8316 (&scan_sh_file): Remove a duplicate pattern.
8317 (&check_configure_ac): Use long options.
8318 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8320 2001-11-26 Akim Demaille <akim@epita.fr>
8322 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8323 Before, having a line containing the opening of a multi line
8324 comment made the whole line be ignored.
8326 2001-11-26 Akim Demaille <akim@epita.fr>
8328 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8329 (testsuite Scripts): Be one of its subsection.
8330 (Autotest Logs): New.
8332 2001-11-26 Akim Demaille <akim@epita.fr>
8334 Test groups are now run two directories deeper.
8336 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8337 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8339 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8340 top_srcdir, builddir and top_builddir.
8341 Use `at_*dir' relatively to the directory containing the
8342 suite, use `*dir' when relatively to the current group dir.
8344 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8346 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8347 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8348 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8351 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8353 * doc/autoconf.texi (Using System Type): Add an example of `case
8354 $host' usage so people quit using `case $target' everywhere.
8356 2001-11-22 Akim Demaille <akim@epita.fr>
8358 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8359 spotted by Jim Meyering.
8361 2001-11-16 Paul Eggert <eggert@twinsun.com>
8363 This patch implements a `long double' suggestion by Oliver Kiddle.
8365 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8366 static, to catch errors if the value isn't known at compile-time
8367 and the compiler supports dynamic arrays. Change its name from
8368 `_array_' to `test_array' to avoid potential name clashes.
8369 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8370 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8371 better than double. Catch a bug in GCC 2.95.2 x86.
8372 * doc/autoconf.texi (C Compiler): Document the above.
8375 2001-11-13 Akim Demaille <akim@epita.fr>
8377 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8379 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8381 2001-11-13 Akim Demaille <akim@epita.fr>
8383 * lib/autotest/general.m4 (AT_INIT): After having run the test
8384 group, go back to the initial directory, not to at_suite_dir.
8386 2001-11-13 Akim Demaille <akim@epita.fr>
8388 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8389 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8390 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8392 (AT_CHECK_CONFIGURE): Use absolute paths.
8393 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8394 The problem is still the old one: there is no means in M4 (that I
8395 know about) to create a defining macro, because there is no means
8396 to create `$1' etc., therefore, the defining macro ``swallows''
8397 all the arguments meant to the defined macro.
8399 2001-11-13 Akim Demaille <akim@epita.fr>
8401 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8402 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8404 * tests/aclocal.m4: Remove, as it is no longer used.
8406 2001-11-13 Akim Demaille <akim@epita.fr>
8408 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8409 variable names when referring to a single test group, or to
8410 `suite' when referring to the whole test suite.
8411 `at_last_test' is removed: m4 compute at_format itself.
8412 (at_stdout, at_stder1, at_stderr): New variables.
8413 (AT_CHECK): Use them.
8415 2001-11-13 Akim Demaille <akim@epita.fr>
8417 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8419 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8420 Do it as soon as a test fails, don't wait till the end of the test
8422 Don't remove $as_me.[0-9]*, since these files no longer exist.
8424 2001-11-13 Akim Demaille <akim@epita.fr>
8426 * tests/tools.at: Use absolute paths, since we are no longer run
8429 2001-11-13 Akim Demaille <akim@epita.fr>
8431 Now that tests are running in their own private dir, there is no
8432 need to list the files to remove at the end of tests groups.
8434 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8435 (AT_data_files, at_data_files): Remove.
8436 (AT_CLEANUP, AT_DATA): Simplify.
8438 Remove the group dir if !debug && !failed.
8439 * tests/atspecific.m4: Adjust.
8441 2001-11-13 Akim Demaille <akim@epita.fr>
8443 Start a new layout for Autotest: `testsuite' creates
8444 `testsuite.dir' in which the at-check-line etc. files are to be
8445 found, and `testsuite.dir/003' where the test group 3 is run.
8447 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8448 at_check_line_file, at_format, at_test_normalized, at_group_dir
8450 Create the directories.
8451 Use absolute paths for at- files.
8454 2001-11-11 Michael Matz <matz@kde.org>
8456 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8458 (m4_car): Properly quote arguments.
8460 2001-11-13 Akim Demaille <akim@epita.fr>
8462 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8463 with stricter rules on LIBOBJS.
8465 2001-11-12 Paul Eggert <eggert@twinsun.com>
8467 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8468 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8471 2001-11-12 Akim Demaille <akim@epita.fr>
8473 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8475 2001-11-12 Akim Demaille <akim@epita.fr>
8477 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8478 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8479 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8480 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8481 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8482 specify to what the macro should be defined (typically to 1).
8484 2001-11-12 Akim Demaille <akim@epita.fr>
8486 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8489 2001-11-12 Akim Demaille <akim@epita.fr>
8491 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8492 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8493 definition used by Automake where LEX is +/- "${missing} lex" and
8494 `missing' itself contains variables.
8496 2001-11-12 Akim Demaille <akim@epita.fr>
8498 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8499 Now that M4sh pushes BODY, the comments were output at the end of
8502 2001-11-08 Akim Demaille <akim@epita.fr>
8504 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8505 that we can trace macros from aclocal.m4.
8506 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8507 obsoleted, and redirect to the former anyway.
8508 Reported by Ralf Corsepius.
8510 2001-11-08 Akim Demaille <akim@epita.fr>
8512 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8513 processed only if present.
8514 * tests/torture.at (Configuring subdirectories): Use autoreconf
8515 instead of successive calls to autoconf.
8516 Add a nonexistent subdirectory to exercise the patch above.
8517 Reported by Ralf Corsepius.
8519 2001-11-08 Kevin Ryde <user42@zip.com.au>
8521 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8522 doesn't accept .S files.
8524 2001-11-07 Akim Demaille <akim@epita.fr>
8526 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8527 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8528 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8529 * bin/autom4te.in (warn_forbidden): New.
8530 (handle_output): Use it.
8531 Read m4_pattern_forbid with messages.
8533 2001-11-05 Akim Demaille <akim@epita.fr>
8535 * bin/autom4te.in (--normalize): Remove.
8536 * lib/autom4te.in: Adjust.
8538 2001-11-05 Akim Demaille <akim@epita.fr>
8540 * tests/Makefile.am (testsuite): Rename this target as...
8541 ($(TESTSUITE)): this.
8544 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8546 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8547 the --prefix option, also remove it's argument.
8549 2001-11-05 Akim Demaille <akim@epita.fr>
8551 * doc/autoconf.texi (testsuite Invocation): Update.
8552 (Writing testsuite.at): Update.
8554 2001-11-03 Akim Demaille <akim@epita.fr>
8556 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8558 2001-11-03 Akim Demaille <akim@epita.fr>
8560 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8561 (&file_name_is_absolute): New, wrappers around routines from
8563 Use and export them.
8564 (&find_configure_ac): Optionally take a directory where to look at.
8565 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8567 Default @ARGV to `.', not find_configure_ac.
8568 (&autoreconf): Argument is a directory.
8569 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8570 * doc/autoconf.texi (autoreconf Invocation): Update.
8572 2001-11-03 Akim Demaille <akim@epita.fr>
8574 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8575 (@export_forward_subs): New.
8576 Add basename, dirname, and fileparse.
8578 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8579 Don't look for aclocal flags if we already know aclocal is not
8581 Move aclocal.m4t only if it exists.
8582 Reported by Ezra Peisach.
8584 2001-11-03 Akim Demaille <akim@epita.fr>
8586 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8587 passed on command line, defaulting to ./configure.ac if present.
8588 (&maybe_autoreconf, File::Find): Remove, unused.
8589 (&autoreconf): If autoconf is not used, don't try to trace.
8591 2001-11-02 Akim Demaille <akim@epita.fr>
8593 * configure.ac: Bump to 2.52g.
8595 2001-11-02 Akim Demaille <akim@epita.fr>
8599 2001-11-02 Akim Demaille <akim@epita.fr>
8601 * config/config.guess, config/config.sub, doc/standards.texi:
8602 * config/lispdir.m4: Update from masters.
8603 * configure.ac: Bump to 2.52f.
8605 2001-11-02 Akim Demaille <akim@epita.fr>
8607 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8608 Don't run aclocal when aclocal.m4 is not from aclocal.
8610 Don't run libtoolize and gettextize if --install is not given.
8612 2001-11-01 Paul Eggert <eggert@twinsun.com>
8614 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8615 be invoked before _AS_LINENO_PREPARE.
8616 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8617 than character ranges.
8619 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8620 invoking AS_BASENAME. Set the locale variables to 'C' if
8621 possible, as POSIX requires this to get the traditional
8623 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8625 2001-10-31 Paul Eggert <eggert@twinsun.com>
8627 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8628 with {}, as that triggers a bug in Bash 2.05.
8630 (_AS_LINENO_PREPARE): Use Sed rather than
8631 Awk. Fix the sed prepass to work even if there are multiple
8632 instances of $LINENO on the same line. Do not substitute for
8633 other variables like $LINENOT. Do not check file dates; such a
8634 check is unreliable on sufficiently fast machines, and removing
8635 the check makes the code simpler and more reliable. Check for
8636 output and chmod failures.
8638 * doc/autoconf.texi (Special Shell Variables): Document
8641 2001-10-31 Akim Demaille <akim@epita.fr>

8648 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8649 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8650 provided, while it is optional.
8651 * configure.ac: Adjust.
8653 2001-10-26 Paul Eggert <eggert@twinsun.com>
8655 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8656 lib/Autom4te/Struct.pm:
8657 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8660 * doc/autoconf.texi (Special Shell Variables): Document some
8661 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8663 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8664 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8665 eval $LINENO is not portable in practice.
8667 2001-10-24 Akim Demaille <akim@epita.fr>
8669 * lib/Autom4te/General.pm (backname): New.
8671 2001-10-24 Akim Demaille <akim@epita.fr>
8673 * m4/: Remove, merged into...
8676 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8678 * doc/autoconf.texi (Shellology): Mention the problems with bash
8679 2.05's use of ANSI quoting in its `set' builtin.
8681 2001-10-22 Paul Eggert <eggert@twinsun.com>
8683 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8684 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8685 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8686 POSIX decided to standardize on the int flavor of strerror_r.
8687 Always do char* test, as there's no reason not to.
8688 Assign to a char* var, to catch strerror_r that returns int*.
8690 * doc/autoconf.texi (Particular Functions):
8691 Document the above changes. Also, document the fact that
8692 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8694 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8696 2001-10-20 Akim Demaille <akim@epita.fr>
8698 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8699 the executable was missing from the log.
8701 2001-10-20 Akim Demaille <akim@epita.fr>
8703 * lib/Autom4te/General.pm (&update_file): If destination is
8704 unchanged, remove the source.
8705 (&up_to_date_p): Don't be verbose, be debug.
8706 * bin/autoreconf.in: No longer support --m4dir.
8707 (&autoreconf): Display the full path of the configure.ac we are
8710 Be sure to honor --force with gettextize.
8712 * doc/autoconf.texi: Adjust.
8714 2001-10-20 Akim Demaille <akim@epita.fr>
8716 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8718 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8719 `intl' is already present, as it refuses unless --force.
8720 (&parse_args): Use -I, --include instead of the old Autoconf
8722 ($localdir, $autoconf_dir): Remove.
8724 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8726 2001-10-19 Jens Petersen <petersen@redhat.com>
8728 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
8729 * doc/autoconf.texi (Particular Programs): Likewise.
8731 2001-10-19 Akim Demaille <akim@epita.fr>
8733 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated

8746 * bin/autoreconf.in (autoreconf): Display the path to the
8747 configure.ac being studied.
8749 2001-10-18 Paul Eggert <eggert@twinsun.com>
8751 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8752 long, to work around a bug in the HP C compiler version HP92453-01
8755 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8756 (AS_BASENAME_EXPR): New macro.

8758 (AS_BASENAME): Use 'basename' if that works; then try 'expr';

9241 and is all that AC_FUNC_GETPGRP's users really need.

9255 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9257 Add test for AS_BASENAME.
9258 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9259 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9260 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9261 * tests/base.at: Fixed the expected responses. The old ones were
9263 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9264 the documentation claims it should (and how it behaved in 2.13).
9266 2001-09-18 Akim Demaille <akim@epita.fr>
9268 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9269 the AC_CONFIG_COMMANDS invocation.
9270 This also solves the name clash problems.
9271 Don't set the package's ID.
9272 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9273 No longer to be shipped.
9274 (version.in): Remove.

9276 * lib/autoconf/status.m4: Adjust.
9277 Use `m4_PACKAGE_STRING'.
9278 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9279 the only optional argument is the name of the test suite.
9280 Expect `package.m4' to define the package signature.
9281 * lib/autom4te.in (Autotest): Add `package.m4?'.
9282 * tests/Makefile.am (package.m4): New.

9302 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9303 Always include <stdio.h> and <stdlib.h>. Evaluate
9304 the expression in an extra function before these includes. Call
9305 fprintf "%d" only after ensuring the argument is of type 'int'.
9306 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9308 2001-09-17 Paul Eggert <eggert@twinsun.com>
9310 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9311 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9312 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9313 when they don't exist.
9315 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9316 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't

9320 version with the version used by fileutils 4.1, except use

9366 * lib/autotest/general.m4 (AT_INIT): Create and remove
9367 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9368 test suites can cohabit.

9372 * tests/mktests.sh: Don't output banners for empty test files.

9478 2001-09-05 Akim Demaille <akim@epita.fr>
9480 Be ready to handle filenames as stupid as `dnl.at', for if even
9481 the maintainer is dumb enough to do that...
9483 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9484 excellence in M4 quotation: consider `__file__' is active.
9486 And BTW, when invoking m4, pass the --include in the right order:

9551 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9552 (testsuite Scripts): There is no such thing as `atconfig.in'.
9553 And actually one diagram is missing: test suite runtime.

9586 * bin/autoheader.in (%symbol): Strip arguments of macros.

9636 Forward autom4te's options instead of interpreting them.

9664 find the executables for it.
9665 * tests/Makefile.am: Major cleanup. Too lazy to document...
9666 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9668 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9669 indeed related to running the test suite, while passing
9670 --autoconf-dir and others is related to running non installed
9671 Autoconf executables. So don't do that, leave it to...

9673 * tests/autoscan: New.
9674 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

9691 Suggested by Paul Eggert.
9693 2001-08-29 Akim Demaille <akim@epita.fr>
9695 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9696 download in a tmp dir.
9698 2001-08-29 Akim Demaille <akim@epita.fr>

10237 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10239 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10240 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10241 * doc/autoconf.texi (C Compiler Characteristics): Update
10242 documentation for AC_C_BIGENDIAN.
10244 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10246 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10247 magic values from an object file when cross-compiling.
10248 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10250 2001-08-10 Akim Demaille <akim@epita.fr>
10252 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10254 Suggested by Russ Allbery.
10256 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10258 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10259 current $prefix to the sub-configures.
10261 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10263 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10264 extension (needed on BeOS). Reported by Guido van Rossum.
10266 2001-08-09 Akim Demaille <akim@epita.fr>
10268 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10270 2001-08-07 Akim Demaille <akim@epita.fr>
10272 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10274 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10275 No need to remove the files before and after the each test, before
10276 each test and at the end of the suite is enough.
10277 Display only the children `times', not the shell's.
10278 If the test failed or was skipped, at-times is not available.
10280 2001-08-07 Akim Demaille <akim@epita.fr>
10282 Always produce testsuite.log, including when there are no
10283 failures. This helps getting information on skipped tests, and
10284 duration of the tests. Err, implement the latter btw.
10286 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10287 Dump information on the first run of each test.
10288 (AT_CLEANUP): Create `at-times' containing the duration of the
10291 2001-08-07 Akim Demaille <akim@epita.fr>
10293 The use of `dumpstat' revealed that `len' was used although it
10294 should not. m4_text_wrap was using it, but in the Autoconf world
10295 where it is legal. Hence (i) test M4sh in its own world, not
10296 Autoconf's, and (ii), ahem, fix the bug :)
10298 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10299 does not like `' instead of [].
10300 (AT_INIT): Forbid `^_?AT_'.
10301 And don't output such tokens.
10302 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10303 `script.as', and `autom4te.cache'.
10304 Remove `empty' and `macro' which are no longer used.
10305 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10306 * tests/m4sugar.at: Use it.
10307 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10309 2001-08-07 Akim Demaille <akim@epita.fr>
10311 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10313 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10315 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10317 2001-08-04 Akim Demaille <akim@epita.fr>
10319 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10320 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10322 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10323 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10324 (AC_F77_MAIN): Likewise.
10326 2001-08-04 Akim Demaille <akim@epita.fr>
10328 Don't rely on M4sugar outputting the patterns in files, since we
10329 might process the output _without_ running m4, hence without these
10332 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10333 * bin/autom4te.in (@Request::includes): Remove, unused.
10334 (@Request::source): Rename as...
10335 (@Request::input): this.
10336 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10337 (&handle_output): Fetch the patterns from the traces.
10338 `$forbidden' and `$allowed' are constant: use m//o.
10339 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10340 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10342 2001-08-04 Akim Demaille <akim@epita.fr>
10344 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10345 autoconf', i.e., in addition to caching traces, cache the output.
10347 * bin/autom4te.in (Request::cache): Rename as...
10348 (Request::id): this.
10349 ($cache, $icache, $tcache, $ocache): New.
10350 (&handle_m4): Save M4 output in the cache instead of $tmp.
10351 (&handle_output): Adjust.
10352 (&up_to_date_p): Check that the output cache is up to date too.
10353 (top level): Run `&handle_m4' iff force or the cache is invalid.
10354 Run `&handle_output' if the output cache is more recent.
10356 2001-08-04 Akim Demaille <akim@epita.fr>
10358 * bin/autom4te.in ($force): New.
10359 (&parse_args, &print_usage): -f, --force is a new option.
10360 (&handle_output): CPP directives might have spaces after `#'.
10361 (&parse_args): The first file only can be frozen.
10363 2001-08-04 Akim Demaille <akim@epita.fr>
10365 Don't let autom4te compute the `include' traces several times:
10366 first check that the trace cache file is up to date, and then
10367 compare its timestamp with that of the output.
10369 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10370 the preamble. Don't require 5.005 as Autom4te::General does it,
10371 and better yet (use `use', not `require'!).
10372 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10373 Class::Struct as Autom4te::Struct.
10374 * lib/Autom4te/General.pm (File::stat): Use it.
10375 (&mtime): New, export it.
10376 * bin/autom4te.in: Use it.
10377 Declare `$req' is invalid if it is outdated.
10378 Don't declare it valid before saving it if something went wrong.
10380 2001-08-04 Akim Demaille <akim@epita.fr>
10382 Autom4te shall not encode Autoconf data, and preselecting traces
10383 must be proposed to the users.
10385 * bin/autom4te.in (@required_trace): Remove.
10387 (&parse_args, &print_usage): -p, --preselect is a new option.
10388 (&up_to_date_p): Adjust.

10391 2001-08-04 Akim Demaille <akim@epita.fr>
10393 * tests/tools.at (autoconf --trace: user macros): Check traces on
10394 macros invoked without arguments, and macros invoked with multiple
10397 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10399 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10402 2001-08-03 Akim Demaille <akim@epita.fr>
10404 * bin/autoconf.in ($@): Work around the usual sh bug.
10407 2001-08-03 Akim Demaille <akim@epita.fr>
10409 Clean up the handling of the M4 builtins tracing exception.
10411 * bin/autom4te.in (Request::request): Don't complete M4 builtins

10414 (@m4_builtin): this.
10415 (%m4_builtin_alternate_name): New.
10416 (&parse_args): Complete the trace requests with alternate names.

10422 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10423 m4_if, and m4_wrap.

10427 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10428 (m4_divert_pop): Dump the whole diversion stack when a diversion
10430 * bin/autom4te.in (&handle_output): Remember of the first
10431 occurrence of a possibly undefined macro, not the last.
10432 Complain about the possibly undefined macros in the same order as
10433 the appear in the output.
10434 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10435 * tests/tools.at (autoconf: forbidden tokens, basic)
10436 (autoconf: forbidden tokens, exceptions): No longer sort
10437 autoconf's stderr, as it is now deterministic.
10438 Check that `dnl' is caught.
10440 2001-08-01 Akim Demaille <akim@epita.fr>
10442 * configure.ac: Bump to 2.52c.

10459 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10460 `END', as `Autom4te::General::END' will be triggered.
10461 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10462 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
10463 system to run `mv', `rm', and `cmp'.

10467 * lib/Autom4te/General.pm (&unique): New.
10468 * bin/autoscan.in (&output): Use it to issue trace requests once.
